Relationship Between Individuals’Epidemic Risk Perception Within Living Space and Subjective Well-Being:Empirical Evidence from China after the First Wave of COVID-19

It is common to observe the epidemic risk perception(ERP)and a decline in subjective well-being(SWB)in the context of public health events,such as Corona Virus Disease 2019(COVID-19).However,there have been few studies exploring the impact of individuals’ERP within living space on their SWB,especially from a geographical and daily activity perspective after the resumption of work and other activities following a wave of the pandemic.In this paper,we conducted a study with 789 participants in urban China,measuring their ERP within living space and examining its influence on their SWB using path analysis.The results indicated that individuals’ERP within their living space had a significant negative effect on their SWB.The density of certain types of facilities within their living space,such as bus stops,subway stations,restaurants,fast food shops,convenience shops,hospitals,and public toilets,had a significantly negative impact on their SWB,mediated by their ERP within living space.Additionally,participation in out-of-home work and other activities not only increased individuals’ERP within living space,but also strengthened its negative effect on their SWB.

The Effects of Childhood Trauma on College Students’Depressive Symptoms:The Mediation Role of Subjective Well-Being and the Moderation Role of Resilience

Background:The enduring and detrimental impact of childhood trauma on later health and well-being is now well established.However,research on the relationship between childhood trauma and depressive symptoms,along with the potential risk and protective factors,is insufficient in the context of Chinese college student population.Methods:Data on childhood trauma,depressive symptoms,resilience,and subjective well-being were collected through surveys conducted with 367 Chinese university students.The data collected in this study were analyzed using SPSS 26.0 and PROCESS 3.5.Results:The results revealed that subjective well-being mediated the relationship between childhood trauma and depressive symptoms among college students,with direct and indirect effects accounting for 59.46%and 40.54%of the total effect,respectively.The pathway process between subjective well-being and depressive symptoms was moderated by resilience,whereby an increase in resilience levels corresponded to a gradual escalation in the predictive power of subjective well-being on depressive symptoms.Conclusion:The study indicates that childhood trauma significantly and positively predicts depressive symptoms among college students,and it can also directly predict depressive symptoms through the mediating effect of subjective well-being.Elevating levels of psychological resilience and subjective well-being among college students can mitigate depression and promote psychological well-being.From the perspective of positive psychology,the present study provides a new perspective for the prevention and intervention of depressive symptoms among college students.

Objective and subjective measures for sleep disorders

Subjective and objective measures of sleep structure or quality could help to characterize the chronic sleep disturbances, with relation to patients＇ risk factor profiles and co-morbidities. Studies have shown that discrepancies can occur between subjective data regarding sleep disturbances and the impact of insomnia and objective assays, and surrogate markers of sleep and sleep disturbances. Both objective and subjective measures should be incorporated into clinic studies. It seems likely that sleep quality is represented by a combination of more than one subjective sleep parameter. Objective and subjective assessments of sleep quality may relate to different parameters. Future studies incorporated both subjective and objective measures could help to address the sleep disorders.

On the Limitary Subjectivity of the Translator——from the perspective of an inter-subjective system

Throughout the past years, the important role of translators has always been overlooked. The invisibility was even taken as one of the standards of a good translator. However, great change happens, especially after the"culture turn"in translation study and the role of the translators has been laid emphasis on. This kind of sharp change has led to two extreme thoughts on this issue: scholars choose either total invisibility or complete subjectivity. This paper puts forward an inter-subjective system, in which the subjectivity should be emphasized only with constraints. The other subjects in the inter-subjective system contribute to the restriction of the subjectivity of the translator during the translation process.By writing this paper, the author wishes to present a comprehensive and balanced way of understanding translators' subjectivity. Therefore, no matter analyzing the translation process or evaluating translation products, people will be more objective towards the role of translators.

冷冻胚胎主体性证成及认定规则的建构

体外受精-胚胎移植技术不断完善,给不孕不育家庭带来了福音,然而由于立法的不完善,冷冻胚胎的法律属性尚未明确规定,实践中极易产生纠纷。以人类辅助生殖技术获取的冷冻胚胎,承载着不孕夫妻的情感寄托,基于法律天理人情,应当具有“准主体”和“准客体”的双重法律属性。在对冷冻胚胎的主体性权益受到损害进行认定时,应当以胚胎移植时间作为其权利能力的赋予依据,可以有效地解决“冷冻胚胎究竟是偏物多一点,还是偏人多一点”的问题,不仅有利于统一司法决策,也有助于限制法官的自由裁量权。

Validation of nutritional risk index method against patientgenerated subjective global assessment in screening malnutrition in colorectal cancer patients

Objective：To validate malnutrition screening tool of nutrition risk index （NRI） against patent-generated subjective global assessment （PG-SGA） as a gold standard tool in colorectal cancer patients before radiotherapy.Methods：Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA （gold standard method） and NRI.Serum albumin levels of patients were determined by colorimetric method.A contingency table was used to determine the sensitivity,specificity,and predictive value of the NRI in screening patients at risk of malnutrition,in comparison with the PG-SGA in patients before radiotherapy.Results：The findings of PG-SGA and NRI showed that 52％ and 45％ of patients in our study were moderately or severely malnourished respectively.The NRI had a sensitivity of 66％ and a specificity of 60％ against PG-SGA.The positive predictive value was 64％ and the negative predicative value was 62％.The agreement between NRI and PG-SGA was statistically insignificant （kappa =0.267; P＞0.05）.Conclusions：The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer.Moreover,NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer.It seems that the combination of anthropometric,laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients.

Non-cycloplegic spherical equivalent refraction in adults:comparison of the double-pass system,retinoscopy,subjective refraction and a table-mounted autorefractor

AIM:To evaluate the accuracy of spherical equivalent(SE) estimates of a double-pass system and to compare it with retinoscopy,subjective refraction and a table mounted autorefractor.METHODS:Non-cycloplegic refraction was performed on 125 eyes of 65 healthy adults(age 23.5±3.0 years) from October 2010 to January 2011 using retinoscopy,subjective refraction,autorefraction(Auto kerato refractometer TOPCON KR-8100,Japan) and a double pass system(Optical Quality Analysis System,OQAS,Visiometrics S.L.,Spain).Nine consecutive measurements with the double-pass system were performed on a subgroup of 22 eyes to assess repeatability.To evaluate the trueness of the OQAS instrument,the SE laboratory bias between the double pass system and the other techniques was calculated.RESULTS:The SE mean coefficient of repeatability obtained was 0.22D.Significant correlations could be established between the OQAS and the SE obtained with retinoscopy(r=0.956,P【0.001),subjective refraction(r=0.955,P【0.001) and autorefraction(r=0.957,P【0.001).The differences in SE between the double-pass system and the other techniques were significant(P【0.001),but lacked clinical relevance except for retinoscopy;Retinoscopy gave more hyperopic values than the double-pass system-0.51±0.50D as well as the subjective refraction-0.23±0.50D;More myopic values were achieved by means of autorefraction 0.24±0.49D. CONCLUSION:The double-pass system provides accurate and reliable estimates of the SE that can be used for clinical studies.This technique can determine the correct focus position to assess the ocular optical quality.However,it has a relatively small measuring range in comparison with autorefractors(-8.00 to +5.00D),and requires prior information on the refractive state of the patient.

Clinical application of subjective global assessment in Chinese patients with gastrointestinal cancer

AIM： To investigate the role of subjective global assessment （SGA） in nutritional assessment and outcome prediction of Chinese patients with gastrointestinal cancer. METHODS： A total of 751 patients diagnosed with gastrointestinal cancer between August 2004 and August 2006 were enrolled in this study. Within 72 h after admission, SGA, anthropometric parameters, and laboratory tests were used to assess the nutritional status of each patient. The outcome variables including hospital stay, complications, and in-hospital medical expenditure were also obtained.RESULTS： Based on the results of SGA, 389 （51.8%）, 332 （44.2%）, and 30 （4.0%） patients were classified into well nourished group （SGA-A）, mildly to moderately malnourished group （SGA-B）, and severely malnourished group （SGA-C）, respectively. The prevalence of malnutrition classified by SGA, triceps skinfold thickness （TSF）, mid-upper arm muscle circumference （MAMC）, albumin （ALB）, prealbumin （PA）, and body mass index （BMI） was 48.2%, 39.4%, 37.7%, 31.3%, 21.7%, and 9.6%, respectively. In addition, ANOVA tests revealed significant differences in body mass index （BMI）, TSF, PA, and ALB of patients in different SGA groups. The more severely malnourished the patient was, the lower the levels of BMI, TSF, PA, and ALB were （P 〈 0.05）. x^2 tests showed a significant difference in SGA classification between patients receiving different types of treatment （surgery vs chemotherapy/radiotherapy）. As the nutritional status classified by SGA deteriorated, the patients stayed longer in hospital and their medical expenditures increased significantly. Furthermore, multiple regression analysis showed that SGA and serum ALB could help predict the medical expenditures and hospital stay of patients undergoing surgery. The occurrence of complications increased in parallel with the increasing grade of SGA, and was the highest in the SGA-C group （23.3%） and the lowest in the SGA-A group （16.8%）. CONCLUSION： SGA is a reliable assessment too and helps to predict the hospital stay and medica expenditures of Chinese surgical gastrointestina cancer patients.

Extension of Subjective Logic for Time-Related Trust

To describe the dynamic propcrty of trust relationship, wt propose atime-related trust model and extend Joang's subjective logic to fit for time-related trust model.The extension includes prepositional conjunction, disjunction and negation for traditional logic anddiscounting and consensus operators that are evidential operators specially designed for thepropagation and computation of trust relationships. With the extension of subjective logic fortime-related trust, our time-related trust modelis suitable to model the dynamic trust relationshipin practice. Finally an example of reputation assessment is offered to demonstrate the usage of ourtrust model.

Factors Influencing Subjective Orthodontic Treatment Need and Culture-related Differences among Chinese Natives and Foreign Inhabitants

Aim The aim of this survey was to compare Chinese natives and foreign inhabitants in Chengdu, China, with respect to： （1） attitudes towards dental appearance, （2） subjective orthodontic treatment need, and （3） the main factors influencing orthodontic treatment need. Methodology A total of 522 subjects, including 227 foreign inhabitants and 295 Chinese natives in Chengdu participated in the survey. A simple random sampling method was adopted and a face-to-face interview was conducted at some public sites using a questionnaire. Data was entered by two persons synchronously using Epidata 3.0, and SPSS 13.0 was used to analyze these data. Results 89.0% of foreign inhabitants were satisfied with their teeth compared to only 46.8% of Chinese natives. Females were more dissatisfied with their teeth than males. Chinese natives put improving appearance as the top priority （55.9%） for seeking orthodontic treatment; however, in foreign inhabitants, the main reason for seeking treatment was to improve masticatory function（44.1%）, followed by ＂to be pretty＂ （35.2%）. The importance of well-aligned teeth and self-perception of psychosocial impact of malocclusion were the same two main factors influencing subjective orthodontic treatment need （P〈0.05） in foreign inhabitants and Chinese natives. Sub- jective orthodontic treatment need between the two target groups was significantly different （P〈0.05）. Conclusion （1） It was very common that Chinese natives were dissatisfied with their dental appearance, and their subjective orthodontic treatment needs were high. （2） There were some differences in orthodontic treatment motives between the two target groups. （3） There were differences in subjective orthodontic treatment needs between foreign inhabitants and Chinese natives. However, the prominent influential factors were almost the same. There may be benefit to understanding subjective orthodontic needs of different races.

TRUST MODEL BASED ON THE MULTINOMIAL SUBJECTIVE LOGIC AND RISK MECHANISM FOR P2P NETWORK OF FILE SHARING

In order to deal with the problems in P2P systems of file sharing such as unreliability of the service,security risk and attacks caused by malicious peers,a novel Trust Model based on Multinomial subjective logic and Risk mechanism(MR-TM) is proposed.According to the multinomial subjective logic theory,the model introduces the risk mechanism.It assesses and quantifies the peers' risk,through computing the resource value,vulnerability,threat level,and finally gets the trust value by the risk value and the reputation value.The introduction of the risk value can reflect the recent behaviors of the peers better and make the system more sensitive to malicious acts.Finally,the effectiveness and feasibility of the model is illustrated by the simulation experiment designed with Peersim.

SUBJECTIVE TINNITUS AS FIRST PRESENTATION IN A PATIENT WITH METASTATIC LUNG CANCER IN TEMPORAL BONE-A CASE REPORT

Metastasis of lung cancer to the temporal bone is a very rare disease and subjective tinnitus as the present-ing symptom in these patients is even rarer. Here we report a case in which a 42-year-old male presented with subjective tinnitus of three months, with no pulmonary disease symptoms. Pure tone audiometry indi-cated moderate conductive deafness in left ear with an air-bone gap of 21.3 dB. HRCT temporal bone scan-ning indicated high-density shadows in the left epitympanic cavity, sinus tympani and mastoid cavity. Chron-ic otitis media with cholesteatoma was suspected and surgical treatment recommended. However, preopera-tive chest x-ray revealed high-density millet lesions scattered widely in both lungs. HRCT lung scanning confirmed the lungs lesions and indicated lung cancer. In order to determine correlations between the tempo-ral bone and pulmonary lesions, a CT-guided trans-mastoid aspiration biopsy and immunohistochemical study were conducted, which confirmed that the temporal bone lesion was metastatic from the lungs. The pa-tient was given a series of chemotherapy immediately and his tinnitus significantly improved after three months of treatment, with full recovery of his hearing and complete resolution of shadows in the mastoid cavity. Unfortunately, he subsequently developed multiple bone metastases in the 9th month and cerebral metastasis in the 18th month. Multiple organ failure resulted in death in 2.5 years.

A New Kind of Subjective Trust Model

Based on the outstanding characteristics of Cloud Model on the process of transforming a qualitative concept to a set of quantitative numerical values, a formalized model of subjective trust is introduced by which we can transform between qualitative reputation and quantitative voting data. The present paper brings forward algorithms to compute direct trust and recommender trust. Further more, an effective similarity measuring method used to distinguish two users＇ reputation on knowledge level is also proposed. The given model properly settles the uncertainty and fuzziness properties of subjective trust which is always the weakness of traditional subjective trust model, and provides a step in the direction of proper understanding and definition of human trust.

A research regarding the relationship among intensive care nurses' self-esteem, job satisfaction and subjective well-being

Objective:The paper aims to explore the status of intensive care unit(ICU)nurses'self-esteem,job satisfaction,and subjective well-being and to investigate the relationship among the three elements.Methods:A cross-sectional survey of 224 nurses from five teaching hospitals in Tianjin,China,was conducted.Self-esteem scale,job satisfaction scale,and subjective well-being scale were used to explore the status of ICU nurses'self-esteem,job satisfaction,and subjective well-being.Correlation among the three elements was calculated by SPSS 17.0.Results:The scores of three scales(i.e.,ICU nurses'self-esteem,job satisfaction,and subjective well-being)were 27.67±3.41,43.57±9.04,and 69.73±11.60,respectively.The subjective well-being was significantly positively correlated with self-esteem and job satisfaction(r=0.454,P<0.01;r=0.584,P<0.01,respectively).Conclusion:The study shows that the prevalence of subjective well-being and self-esteem with ICU nurses are at a low level,and job satisfaction is at the median level.Associations among self-esteem,job satisfaction,and subjective well-being in ICUs have been confirmed.Self-esteem and job satisfaction positively correlated with nurse subjective well-being.The higher the self-esteem and job satisfaction levels are,the stronger the subjective well-being is.The working pressure in ICUs cannot be alleviated temporarily;hence,to promote a high subjective well-being,managers and ICU nurses increase their self-esteem and job satisfaction through taking strategies that strengthen psychological construction.

An Evaluation Approach of Subjective Trust Based on Cloud Model

As online trade and interactions on the internet are on the rise, a key issue is how to use simple and effective evaluation methods to accomplish trust decision-making for customers. It is well known that subjective trust holds uncertainty like randomness and fuzziness. However, existing approaches which are commonly based on probability or fuzzy set theory can not attach enough importance to uncertainty. To remedy this problem, a new quantifiable subjective trust evaluation approach is proposed based on the cloud model. Subjective trust is modeled with cloud model in the evaluation approach, and expected value and hyper-entropy of the subjective cloud is used to evaluate the reputation of trust objects. Our experimental data shows that the method can effectively support subjective trust decisions and provide a helpful exploitation for subjective trust evaluation.

Family care and subjective well-being of coronary heart disease patients after percutaneous coronary intervention:Mediating effects of coping strategies

Objectives To analyze the correlations between family care,coping strategies and the subject well-being(SWB)of patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods From November 2019 to October 2020,264 CHD patients who had undergone PCI were enrolled in this questionnaire survey.The research tools applied included General Information Questionnaire,the Adaptation,Partnership,Growth,Affection and Resolve,Medical Coping Modes Questionnaire,and the General Well-being Schedule.SPSS 24.0 and Amos 23.0 software packages were used for statistical analysis.Results The mean scores for family care,confrontation,avoidance,acceptance-resignation and SWB,were 7.59±2.24,20.03±3.78,16.49±2.70,10.42±2.01,and 73.31±11.63,respectively.Subgroup analysis showed that the path coefficient between family care and subjective well-being was higher in males than females.Family care was directly related to coping strategies.The coping strategies were directly related to SWB,while family care showed an indirect association with SWB via coping strategies.Conclusions Family care can improve CHD patients’SWB post-PCI,and coping strategies are important for the link between family care and SWB.Also,men received more family care than women.Based on a patient's characteristics,healthcare providers can promote patients’positive coping strategies,increase their perceived family care,and improve the patient's SWB.

Perceptual Quality Assessment of Omnidirectional Images:Subjective Experiment and Objective Model Evaluation

Virtual reality(VR) environment can provide immersive experience to viewers.Under the VR environment, providing a good quality of experience is extremely important.Therefore, in this paper, we present an image quality assessment(IQA) study on omnidirectional images. We first build an omnidirectional IQA(OIQA) database, including 16 source images with their corresponding 320 distorted images. We add four commonly encountered distortions. These distortions are JPEG compression, JPEG2000 compression, Gaussian blur, and Gaussian noise. Then we conduct a subjective quality evaluation study in the VR environment based on the OIQA database. Considering that visual attention is more important in VR environment, head and eye movement data are also tracked and collected during the quality rating experiments. The 16 raw and their corresponding distorted images,subjective quality assessment scores, and the head-orientation data and eye-gaze data together constitute the OIQA database. Based on the OIQA database, we test some state-of-the-art full-reference IQA(FR-IQA) measures on equirectangular format or cubic formatomnidirectional images. The results show that applying FR-IQA metrics on cubic format omnidirectional images could improve their performance. The performance of some FR-IQA metrics combining the saliency weight of three different types are also tested based on our database. Some new phenomena different from traditional IQA are observed.

Subjective annoyance caused by indoor low-level and low frequency noise and control method

The influence of low_level noise has not been widely noticed. This paper discovered that low_level and low frequency noise(A_weighted equivalent level L eq <45 dB) causes higher probability of subjective annoyance. The fuzzy mathematic principle was applied to deal with the threshold level of subjective annoyance from noise in this study; there is preferable relationship between the indoor noise and noise annoyance at low frequency noise level. Study indicated at the same centered noise level, the change of annoyance probability is mainly caused by the change of the frequency spectrum characteristic of the indoor noise. Under low noise level environment, without change of the medium_low frequency noise, the slight increase of medium_high frequency noise level with the help of noise sheltering effect can significantly reduce the noise annoyance. This discovery brings a new resolution on how to improve the environmental quality of working or living places. A noise control model is given in this study according to the acoustic analysis.

Assessing the severity of methamphetamine use disorder beyond the subjective craving report: the role of an attention bias test

Background Methamphetamine (MA) is one of the most commonly abused illicit psychostimulant drugs and MA use disorder constitutes a universal health concern across the world. Despite many intervention approaches to MA use disorder, the indicator of addiction severity is mainly limited to subjective craving score to drug-related cues, which is influenced by many factors such as social approval and self-masking. Aim The present study investigates whether self-reported craving for drug use in response to MA cues is a reliable indicator for addiction severity in MA users, and then tests the validity of the cue-induced attention bias test in addiction severity assessment. Methods Fifty-two male MA users completed the cueinduced craving test and attention bias task, and were required to report clinical characteristics of addiction severity. For the attention bias test, subjects were required to discriminate the letter superimposed onto MA userelated or neutral scenes. The reaction time delay during MA-use condition relative to neutral condition was used as an index of the attention bias. Results The results showed that 24 of the 52 MA users rated non-zero in cue-induced craving test, and they showed a significant attention bias to drug-related pictures. However, the other 28 users who rated zero in cue-induced craving evaluation showed a similar attention bias to drug-related cues. In addition, the attention bias to MA use-related cues was significantly and positively correlated with the clinical indexes of addiction severity, but the relationship was absent between subjective craving evaluation and the indexes of addiction severity. Conclusion These results suggest that attention bias to MA cues may be a more reliable indicator than experiential craving report, especially when subjective craving is measured in the compulsory rehabilitation centre.
