This paper proposes an artificial intelligence-based robust information hiding algorithm to address the issue of confidential information being susceptible to noise attacks during transmission.The algorithm we designed aims to mitigate the impact of various noise attacks on the integrity of secret information during transmission.The method we propose involves encoding secret images into stylized encrypted images and applies adversarial transfer to both the style and content features of the original and embedded data.This process effectively enhances the concealment and imperceptibility of confidential information,thereby improving the security of such information during transmission and reducing security risks.Furthermore,we have designed a specialized attack layer to simulate real-world attacks and common noise scenarios encountered in practical environments.Through adversarial training,the algorithm is strengthened to enhance its resilience against attacks and overall robustness,ensuring better protection against potential threats.Experimental results demonstrate that our proposed algorithm successfully enhances the concealment and unknowability of secret information while maintaining embedding capacity.Additionally,it ensures the quality and fidelity of the stego image.The method we propose not only improves the security and robustness of information hiding technology but also holds practical application value in protecting sensitive data and ensuring the invisibility of confidential information. 展开更多

BACKGROUND Irritable bowel syndrome(IBS)is a common digestive system disease with a high incidence rate and is common in women.The cause of IBS remains unclear.Some studies have shown that mental and psychological diseases are independent risk factors for IBS.At present,the treatment of IBS is mainly symptomatic treatment.Clinically,doctors also use cognitive behavioral therapy to improve patients'cognitive ability to diseases and clinical symptoms.In recent years,exercise therapy has attracted more and more attention from scholars.Improving the symptoms of IBS patients through psychosomatic treatment strategy may be a good treatment method.AIM To explore the effects of an intervention of cognitive behavioral therapy combined with exercise(CBT+E)on the cognitive bias and coping styles of patients with diarrhea-predominant irritable bowel syndrome(IBS-D);and to provide a theoretical reference for the management of IBS.METHODS Sixty IBS-D patients and thirty healthy subjects were selected.The 60 IBS-D patients were randomly divided into experimental and control groups.The experimental group was treated with the CBT+E intervention,while the control group was treated with conventional drugs without any additional intervention.The cognitive bias and coping styles of the participants were evaluated at baseline and after 6 wk,12 wk and 24 wk using the Automatic Thoughts Questionnaire(ATQ),Dysfunctional Attitudes Scale(DAS)and Pain Coping Style Questionnaire(CSQ)instruments,and the intervention effect was analyzed using SPSS 17.0 statistical software.RESULTS At baseline,the scores on the various scales showed that all subjects had cognitive bias and adverse coping styles.The IBS Symptom Severity Scale(IBSSSS)scores,ATQ total scores,DAS scores and CSQ scores of the two groups were not significantly different(P>0.05).Compared with baseline,after 6 wk of the CBT+E intervention,there were significant differences in the ATQ scores,the dependence and total scores on the DAS,and the catastrophization,distraction and prayer scores on the CSQ(P<0.05).After 12 wk,there were significant differences in the scores for perfectionism on the DAS and in the scores for reinterpretation,neglect and pain behavior on the CSQ in the experimental group(P<0.05).After 24 wk,there were significant differences in the vulnerability,dependence,perfectionism,and total scores on the DAS and in the catastrophization,distraction and prayer scores on the CSQ in the experimental group(P<0.01).The IBS-SSS scores were negatively correlated with the ATQ and DAS total scores(P<0.05)but were positively correlated with the CSQ total score(P<0.05).CONCLUSION Intervention consisting of CBT+E can correct the cognitive bias of IBS-D patients and eliminate their adverse coping conditions.CBT+E should be promoted for IBS and psychosomatic diseases. 展开更多

Attachment theory suggests that anxious attachment is associated with hypervigilance to threatening social stimuli, and avoidant attachment with avoidance or suppression of processing such stimuli. Twenty-five students viewed angry, fearful and neutral female faces in four visual oddball tasks, and completed the Attachment Style Questionnaire, the Autonomy-Connectedness Scale, and Anxiety and Depression subscales of the Symptom Checklist-90. When the oddballs were angry faces in a background of neutral frequents, we found higher levels of autonomy and secure attachment to be related to larger N100 and smaller P300 amplitudes;higher levels of anxious attachment were, on the contrary, associated with smaller N100 and larger P300 amplitudes. Variation in attachment is related to approaching, or withdrawing from threatening stimuli, and ERP-techniques add to our understanding of how the attachment system actually works. 展开更多

In this study, the relationship between social anxiety, coping style and loneliness amongst left-behind children was investigated. The participants were 773 left-behind children recruited from 8 junior middle schools in rural areas of Zhejiang Province in China who completed the Social Anxiety Scale for Children, Simplified Coping Style Questionnaire and Children’s Loneliness Scale. Results show that there was a moderate correlation between social anxiety and loneliness, and these variables had a significant negative relationship with positive coping style and a significant positive relationship with negative coping style. Furthermore, the left-behind children’s social anxiety, coping style and loneliness were different within specific demographic groups, such as gender, only child status and different type of parental work. Also negative coping style moderated the association between loneliness and social anxiety, so that children who were more likely to use negative coping strategies showed a stronger relationship between social anxiety and loneliness. Finally, the left-behind children’s social anxiety not only directly predicted their loneliness, but also had an indirect effect mediated by their copying style. 展开更多

The West Junggar region, located in the loci of the Central Asian Orogenic Belt, is a highly endowed metallogenic province with 〉100 tonnes Au, 〉0.7 Mt Cu, 〉0.3 Mt Mo, and 〉2.3 Mt chromite as well as significant amounts of Be and U. The West Junggar region has three metallogenic belts distributed systematically from north to south: (1) late Paleozoic Saur Au-Cu belt; (2) early Paleozoic Xiemisitai- Sharburt Be-U-Cu-Zn belt; (3) late Paleozoic Barluk-Kelamay Au-Cu-Mo-Cr belt. These belts host a number of deposits belonging to at least eight economically important styles, including epithermal Au, granite-related Be-U, volcanogenic massive sulfide (VMS) Cu-Zn, podiform chromite, porphyry Cu, hydrothermal quartz vein Au, porphyry-greisen Mo(-W), and orogenic Au. These deposit styles are associated with the tectonics prevalent during their formation. Five tectonic-mineralized epochs can be recognized: (1) Ordovician subduction-related VMS Cu-Zn deposit; (2) Devonian ophiolite-related podiform chromite deposit; (3) early Carboniferous subductionrelated epithermal Au and porphyry Cu deposits; (4) late Carboniferous subduction-related granite-related Be-U, porphyry Cu, and hydrothermal quartz vein Au deposits; and (5) late Carboniferous to early Permian subduction-related por- phyry-greisen Mo(-W) and orogenic Au deposits. 展开更多

We used data of 3,238 men (39.3 ± 10.5 years) and 5,111 women (37.1 ± 10.9 years), aged 20 - 59 years, by cross-sectional clinical investigation study. Work style i.e. day work and shift work, cigarette smoking, status of stress and stress coping were obtained by questionnaires by well-trained medical staff. A total of 227 men (7.0%) and 339 women (6.6%) were shift workers, and 1346 men (41.6%) and 649 women (12.7%) were current smokers. Work style was significantly linked to cigarette smoking, stress and stress coping after adjusting for age in women. In addition, the level of stress coping in subjects with cigarette smoking was significantly lower than that in subjects without cigarette smoking even after adjusting for age in women. However, these associations were not noted in men. Work style was critically associated with cigarette smoking in Japanese female workers. 展开更多

OBJECTIVE: To explore the effects of acupoint massage combined with psychological nursing on depression and hope level and coping style in hospitalized patients with hepatocirrhosis, and to provide scientific basis for clinical treatment. METHODS: A total of 86 patients with hepatocirrhosis hospitalized in The Sixth Hospital of Handan from June 2015 to June 2018 were selected and divided into 2 groups according to the nursing method. The control group, with a total of 42 patients, were given psychological nursing intervention. The observation group, with a total of 44 patients, were given acupoint massage and psychological nursing intervention. Changes in depression levels, hope levels, and coping style scores were compared between the 2 groups. RESULTS: There was no significant difference in depression, hope level and coping style before the intervention between the 2 groups(P > 0.05). In the observation group, the self-rating depression scale(SDS) score of depression before intervention was 55.16 ± 4.17; and the positive attitude score was 8.40 ± 2.02; the positive action score was 8.33 ± 3.05; and the intimate score was 8.13 ± 2.44. The negative response score was 30.14 ± 3.31, and the positive response score was 30.49 ± 3.26. Before the intervention, the SDS score in the control group was 56.81 ± 4.39, and the positive attitude score was 8.29 ± 1.98. The positive action score was 8.04 ± 2.57, and the intimate score was 8.06 ± 2.31. The total level of hope score was 24.07 ± 3.11. The negative coping score was 30.55 ± 3.06, and the positive coping score was 30.93 ± 3.17. After intervention the SDS scores of the observation group were lower than those of the control group(P < 0.05). The SDS score of the observation group was 36.19 ± 4.19, and the SDS score of the control group was 42.95 ± 3.71. The total level of hope in the observation group was higher than that in the control group after intervention(P < 0.05). The positive attitude score of the observation group was 16.10 ± 2.15, and the score of positive action was 14.74 ± 3.11; the score of intimate relationship was 15.08 ± 5.45; and the total score of hope was 45.71 ± 5.63. The positive attitude score of the control group was 10.92 ± 2.07; the score of positive action was 11.38 ± 3.14; the score of intimate relationship was 10.92 ± 2.33; and the total score of hope was 34.09 ± 5.77. The patients in the observation group had lower response scores after intervention than the control group, and the positive response scores were higher than those in the control group(P < 0.05). The negative response score of the observation group was 20.14 ± 2.19; the positive response score was 38.92 ± 4.33; the negative response score of the control group was 26.61 ± 2.34; and the positive response score was 34.08 ± 2.69. CONCLUSION: Acupoint massage combined with psychological nursing can effectively improve depression in hospitalized patients with hepatocirrhosis, improve the patient's hope level, help patients cope with lifestyle changes from negative to positive, which is worthy of clinical promotion. 展开更多

The problem of old-age care in China is more and more serious. Under the background of continuous promotion of community old-age, the importance of research on the"family" life style of oldage residential facilities has become increasingly prominent. Through field survey of different types of oldage residential facilities and questionnaire interviews, the shortcomings of the old-age residential facilities in Xi’an were compared and summarized, and the key elements of "family" life style of the old-age residential facilities were concluded, which mainly include urban community embeddedness, family structure elements, indoor furnishings and accompanying care system. The "family" life style of the old-age residential facilities can not only maintain the "kinship" living needs, but also conform to the new direction of promoting the "community" of the old-age residential facilities in China. 展开更多

Life expectancy was well known to associate with lifestyle habits, socioeconomic condition, and three health-related dimensions (physical, mental and social health status). However, the causal effect relationship among these variables remains unclear. The purpose of this study was to determine the causal relationships among health and life conditions, socioeconomic status, dietary and lifestyle habits and three health-related dimensions in elderly urban dwellers in Tokyo, Japan. Of 16,462 eligible elderly individuals aged 65 years and older, 13,195 participants responded to the questionnaire survey conducted in September 2001 (a response rate of 80.2%). A follow-up survey was conducted in September 2004 and a total of 8162 survivors were followed until the end of August 2007 through the municipal resident's registry. Exploratory factor analysis defined five latent variables based on the 13 observed variables. From a cross-lagged effects variation model using structural equation modeling, causal relationships were analyzed using longitudinal data obtained at the 2001 and 2004 survey and the number of survival days between 2004 and 2007. After estimating a best-fit model, we discovered that health and life conditions were not determined by current dietary and lifestyle habits, which many studies showed.
