This study compared the temperament and character of problematic internet users (PIU) with that of problematic drug users (PDU) among Korean adolescents and aimed to examine the personality characteristics of adolescents with internet use problems. Method: We enrolled participants from high schools (n = 487), internet cafés (n = 89), and an adolescent-substance abuse consultation office (n = 45). All subjects were assessed using the Korean Internet Addiction Scale (KIAS), the Korean Adolescent Drug Addiction Screening Test-2 (KOADAST-2), and the Korean version of the Temperament and Character Inventory (K-TCI). Subjects were classified into the following four groups based on the KIAS and KOADAST-2 results: normal controls, pure PIUs, pure PDUs, and dual problematic users. Differences in the subscale scores on the K-TCI were analyzed by group. Results: Scores for Reward dependence (RD) were significantly lower in pure PIUs than in pure PDUs (13.85 ± 4.07 versus 15.44 ± 3.56, p < 0.05). Scores for Self-Directedness (SD) were lower in pure PIUs (18.21 ± 6.90) and pure PDUs (18.22 ± 6.03) than in normal controls (20.88 ± 6.60), although the scores did not differ significantly between pure PIUs and pure PDUs. Scores for Cooperativeness (C) were lower in pure PIUs than in normal controls (23.97 ± 7.02 versus 26.57 ± 6.67, p < 0.05). Conclusions: The results of this study suggest that PIUs are more socially insensitive and that they may experience more inter-personal problems than PDUs.展开更多

By adopting the im-proved real-coded accelerating genetic algorithm (RAGA), the projection direction is optimized and multi-dimensional indexes are converted into low-dimensional space. Classification of wetland soils and evaluationof wetland soil quality variations are realized by pursuing optimum projection direction and projection func-tion value. Therefore, by adopting this new method, any possible human interference can be avoided andsound results can be achieved in researching quality changes and classification of wetland soils.展开更多

In this study, we reexamined their relationships with seven speeds by a simple character discrimination task using an infrared eye tracker. Our results found that the pursuit velocity and accuracy were non-linearly related with the target velocity. Besides, the perceptual sensitivity was not linearly related with the pursuit velocity either. A significant difference existed between lower (less than 20 deg/s) and higher speeds (greater than 20 deg/s). In addition, we found there was no position bias of visual sensitivity between ahead of and behind the pursuit target, but there was a significant perceptual dissymmetry between horizontal and vertical directions at lower pursuit speeds.展开更多

Motor activity in childhood and mental vitality, sociability and positive emotionality in adolescence were associated with apoE. Two research groups have attempted to replicate these findings but no associations have been found. Purpose: The purpose of the present study was to confirm the original findings with new and more reliable genotyping from a larger sample derived from the same Young Finns Study as the original finding.Methods: The study included 2808 participants aged 3 - 18 years in 1980. The same methods in assessing temperament were used as in the original study. Temperament was operationalized as motor activity, cooperativeness, negative emotionality, mental vitality, sociability and positive emotionality. Temperament was assessed by participants’ mothers in 1980 and 1983 and self-rated in 1983 by adolescent participants. Results: Motor activity was not associated with apoE polymerphisms. All other previous results were replicated. Adolescents’ positive emotionality, mental vitality and sociability were associated with apoE. Conclusions: The results indicated that there is an association between temperament and apoE. The previous absence of association between temperament and apoE in the replication studies may be due to the fact that researchers used different dimensions of temperament and thus probably studied different phenomena. Cultural differences in personality assessment might also explain the contradictory findings.展开更多

Methods: 40 RA patients who had undergone operations on their MP joints were investigated in a one-year fol- low-up. Objective measurement to assess grip strength and active range of motion—Paper- pencil-tests to assess pain during activity and at rest performance, QoL, and personality. Results: Significant improvement was observed in func- tion and pain related scores except for the pain related VAS and in several QoL facets and do- mains. Patients who experienced improvement reported higher scores on the activities of daily living facet of the WHO QoL questionnaire. Those with lower pain showed more independ- ence. The variance of the QoL domain scores, other than social and physical domains, could substantially and meaningfully be explained by variance of objective measures combined with personality scores. Conclusions: Most RA pa- tients’ QoL can be improved by MP arthroplasty despite remaining substantial level of pain. NS and HA seem to play an important role in the adaptation process during the long term, chronic illness;whereas SD represents a tool of coping with the burden of pain and disability. Personal- ity characteristics are highly predictive for QoL suggesting their important mediating role be- tween experienced pain and disability and HR QoL.展开更多

文摘Invisible Man is a representative work of black literature in America.In this novel,the writer Ralph Ellison depicts the hero’s growth experience in the white dominated society with his unique narrative techniques.As an individual in a society,the hero in this novel gradually realizes that he is an invisible man in the white dominated society and he doesn’t have the social sta tus which can be recognized by the white at all.To change this situation,the hero in this novel suffers many difficulties and hard ships with an attempt to prove his existence in front of the white and the numerous black fellows and obtain his own identity as a black man which will be recognized by others.This paper tries to explore African American’s pursuit of identity in Invisible Man by interpreting Ellison’s Invisible Man.
