  • In this study, using a continuous behavior measurement technique, the short-term behavioral responses and tolerance limits of red seabream Pagrus major fingerlings to sudden exposure to low salinity in a controlled environment were observed. The activity of the fingerlings suddenly exposed to 21.4, 17.3, and 9.8 psu increased temporarily at the initial exposure to show irregular swimming behavior, but then recovered a stable activity pattern through rapid salinity adaptation. However, the organisms suddenly exposed to 7.3 and 4.3 psu could not withstand the salinity stress, and their swimming behavior was severely disturbed and all individuals died within 48 hours. The findings suggest that red seabream underwent a temporary salinity stress process at the beginning of the exposure to concentrations of 10.0 psu or higher. At these concentrations, osmotic control was possible within at least 11 hours, so stable metabolic activity was also possible. However, organisms suddenly exposed to concentrations below 5.0 psu exceeded the tolerance to low salinity and the sublethal limit. In red seabream exposed to this concentration range, severe behavioral and metabolic disturbances were observed, and death was observed due to osmotic control failure. In conclusion, a salinity range of 5.0 to 10.0 psu can be predicted to correspond to a concentration range in which the osmotic control ability of the red seabream fingerlings is lost, and sub-lethal reactions occur.

  • Objective : The purpose of this study was to investigate the relationship between the pattern of computer game play and emotional and behavioral characteristics of 5th and 6th grade elementary school children in Jeonju city. Methods : Fifth and sixth graders from two elementary schools (N=413, M=214, F=199) were chosen to participate in this study. The participants completed self-report questionnaires designed by the authors, and were also evaluated based on a computer game addiction scale, state-trait anxiety inventory for children, children's depression inventory and Piers-Harris children's self-esteem scale. The parents of the participants determined the disruptive behavior rating scale of the participants. Results : Positive links were reported between the pattern of computer game play (years of computer game experience, average length of each computer game play session, average time spent on computer game play per day, and average frequency of computer game play per week) and scores of computer game addiction scale. In addition, significant correlation was found between the internalized problems of children (trait anxiety, state anxiety, depression, and self-esteem), and computer game addiction scale score, among both sexes (p<0.01). There were significant correlations between game addiction scale score and inattention (p<0.01) as well as total attention deficit hyperactivity disorder (ADHD) score (p<0.05) in girls. Conclusion : Our findings suggest that computer game addiction is related to symptoms of internalizing, particularly to the trait anxiety. Significant positive correlations between game addiction scale score and externalized behavioral problems were found only in girls.

  • On-line consumers have some visit behavior characteristics when they visit internet-shopping mall between visit-stage and purchase-stage. Therefore, information of on-line consumers have influenced on internet-shopping mall's profitabilities at site manager's perspectives. For examples, Are any on-line consumers continuous visiting under any situations? Or are any on-line consumers purchased on any specific internet-shopping mall? Expecially in this paper, researcher tried to understand visit behavioral characteristics of on-line consumers using two-stage mixture regression analysis. Throughout this process, it could be proposed method, which could be reinforced competitiveness of internet-shopping mall by segmental decision-making method. Additionally, it is expected that visit behavioral characteristics' information could be supplied strategic implications between visit-stage and purchase-stage Throughout empirical test it could be proved two-stage decision-making process, which decision-making process of on-line consumers would be processed visit-stage and purchase-stage. In this study, researcher proposed suitable response strategy after understanding visiting behavioral characteristics of on-line consumers. This paper has some academical contributions, which visit behavioral characteristics of on-line consumers could be grasped the meaning by site stickiness and navigation pattern.

  • Stress and fatigue are general physical aspects of our daily lives. It has been shown that physical therapists have different levels of job stress and fatigue according to the type A/B behavior patterns. This study collected data from 212 physical therapists between October 28 and November 23, 2016 using an anonymous, self-administered questionnaire. The study results showed the proportion of physical therapists with the Type A behavior patterns(TABP) was 18% greater than that of physical therapists with the Type B behavior patterns(TBBP). In this study, physical therapists with TABP were compared with physical therapists with TBBP. The results indicated that physical therapists with TABP were more inclined to experience higher levels of overall job stress and fatigue from the following stress factors: physical environment, job requirement, and job autonomy. Therefore, the stronger the tendency toward TABP, the stronger the feeling of job stress and fatigue from physical environment, job requirement, and job autonomy. Those with a tendency toward TBBP showed positive correlations between job requirement and the total job stress score; thus, the stronger the tendency toward TBBP, the stronger the feeling of overall job stress and fatigue from job requirement. This study suggests that it is necessary to manage the job stress and fatigue of physical therapists with both TABP and TBBP and to manage the job stress and fatigue of physical therapists with the type A behavioral pattern.

  • This study was conducted to identify major dietary patterns of generally healthy Korean middle-aged women and to examine associations of the dietary patterns with socio-demographic, psychological, and physical characteristics. Data were drawn from the 2001 Korean National Health and Nutrition Examination Survey (KNHANES), which is an ongoing national surveillance system. Healthy female subjects aged 40-64 years and provided the health interview examination and food frequency questionnaire (FFQ) data were included. We conducted factor analysis based on daily mean intake frequency of 26 food groups and identified 3 major dietary patterns, healthy, convenient, and alcohol-animal. The healthy pattern was characterized by higher intakes of fish, seafood, poultry, mushroom, seaweed, vegetable, tomato, potato, and fruit, the convenient pattern by processed meat and fish, ramen, noodle and rice cake, sweet snack, egg, bread, and fast food, and the alcohol-animal pattern by alcohol, poultry, meat, and fish. The healthy pattern was significantly related with higher socio-economic status, more stable family structure, healthier mentality, and sounder status of anthropometric and biochemical variables. Those with higher factor scores for the convenience pattern were found to be younger and having higher socio-economic status, higher subjective levels of health, and lower subjective levels of worry on health. Several physical characteristics significantly improved as the levels of the convenience pattern increased. The alcohol-animal pattern was significantly associated with several socio-demographic characteristics including a low education level, a young age, a small family size, and blue-collar jobs. Public health policy makers can utilize the study findings to select prior target populations with higher needs and to tailor dietary behavioral messages to lower chronic disease risks among Korean middle-aged women.

  • Approximately equivalent to character disorder or character neuroses or behavioral reaction. For a discussion of the term as used currently, in the 1968 revision of psychiatric nomenclature(DSM-II). In DSM-I(1952 nomenclature), this term referred to those cases in which the personality, in its struggle for adjustment to internal and external stresses, utilized primarily a pattern of action or behavior rather than symptoms in the mental, somatic or emotional spheres. There is minimal subjective anxiety and little or no sense of distress. As thus defined, there are three main groups of personality disorder, personality pattern disturbance, personality trait disturbance and sociopathic, personality disturbance. Morton Prince asks whether a subconscious process can perform the same function as are ordinarily performed by conscious intelligence that is to say memory, perception, reasoning, imagination, volition, affectivity, etc? He cites clinical material at great length, concluding that the quality of the functions performed they frequently exhibit, that which is characteristic of intelligence.
