To stress the importance of privacy in social networking, I presented an analysis on how information control and information management vulnerability influence trust and privacy concerns in social networking, and how trust and privacy concerns influence the sustainable usage intention of social network services. I also analyzed the factors affecting privacy concerns to present the method to alleviate social network users' concerns about privacy. Information collection control, information processing control and information management vulnerability were chosen and analyzed as the factors affecting privacy concerns. The results showed that information collection control and information management vulnerability significantly affected trust and privacy concerns; and information processing control did not significantly affect privacy concerns. The relationship between trust and privacy concerns, and sustainable usage intention was statistically significant; and the relationship between trust and expansion of communication channels was also statistically significant.

Objective : The purpose of this study was to investigate differences in anxiety and depression symptoms, comorbidity according to the patterns of temperament and character in patients with posttraumatic stress disorder (PTSD). Methods : The temperament and character inventory (TCI), beck depression inventory (BDI) and beck anxiety inventory (BAI) were administered to 151 PTSD patients classified into four groups of adaptation, vulnerable temperament, immature personality and composite vulnerability according to the results of the Temperament and Character Inventory (TCI). MANOVA and Chi-square tests were conducted to analyze differences in BDI, BAI, temperament and character scores and rate of comorbid disorders between the four groups. Results : The immature character and complex vulnerability group showed the higher rate of comorbid depression disorder. Anxiety and depression severity were significantly different among groups, especially depression severity had higher scores in the immature character and complex vulnerability groups and anxiety severity had higher scores in the complex vulnerability group than adaptive group. The immature character and complex vulnerability groups showed significantly lower score on the temperament scale of reward dependence and persistent. Conclusion : The results demonstrate the significance of adaptive characteristics on anxiety and depression symptoms regardless of vulnerable temperaments, and its consequent role in the management of character factors relative to intervention regarding PTSD.

There are less studies on the elderly suicide even though it's steep increase. The purpose of the present study was to investigate factors that influence on the elderly suicide and to categorize them. For these purpose, A total of 23 cases were analyzed through qualitative contents analysis. Specifically, on the basis of the stress-vulnerability model, we scrutinized vulnerability factors(classified personal, family-environment factors) and precipitating events(classified interpersonal events) influencing on the elderly suicide. Personal factor was to be classified into personal mental health, physical health and problematic behavior. Family-environment factor was divided family relationship problem and economic problem. Interpersonal events belonging to the precipitating events was to be classified into interpersonal loss and interpersonal conflict. As the results of this study, elderly suicide classified into 3 types, that is, 'risk type suicide', 'event-response type suicide', 'complex type'. And then we discussed the characteristics of the suicidal types and suggestions for reduction of elderly suicide.

There are less studies on the adult suicide even though it's steep increase and negative effect on person itself, family and society. The purpose of the present study was to investigate factors that influence on the adult suicide and to categorize it. Using a case-study approach, a total of 61 cases were analyzed. Specifically, on the basis of the stress-vulnerability model, I scrutinized vulnerability factors(classified personal, family-environment, and social-environment factors) and precipitating events(classified personal, interpersonal events) influencing on the adult suicide. As the results of this study, adult suicide classified into 3 types, that is, 'risk type suicide', 'event-response type suicide', 'complex type'. And then I discussed the characteristics of the suicidal types and the method for reduction of adult suicide.

A methodology to evaluate fatigue vulnerability of steel bridge members affected by corrosion and truck traffic variation is proposed. A fatigue limit state function including corrosion and traffic variation effects is established to make the criterion whether the steel bridge member is damaged by fatigue. Corrosion effects are expressed as increase of the average corrosion depth, and the traffic variation effects are modeled as the accumulated number of stress cycles. Reliability analysis is carried out by Monte-Carlo simulation method for the fatigue limit state function. The methodology Proposed is verified by comparing reference study and applying for the steel bridge in service.

Financial soundness in the household sector matters for financial stability and for the real economy. The level of household debt in Korea raises concern about the financial soundness of the household sector due to its size, growth rate and quality. Against this backdrop, we assess the financial vulnerability of borrowers based on an analysis of credit bureau (CB) data, in which the actual credit activities of most individuals are recorded at a high frequency in Korea. We construct over-indebtedness indicators from the CB data and then assess the predictability of forthcoming defaults. Based on the over-indebtedness indicators, we show how borrowers are distributed in terms of over-indebtedness and how the over-indebted differ from average borrowers in terms of their characteristics. Furthermore, we show how the aggregate credit risk in the household sector would change under macroeconomic distress by analyzing how each borrower's credit quality would be affected by adverse shocks. The findings of this paper may contribute to assessing household debt vulnerability and to enhancing regulatory and supervisory practices for financial stability.

For the purpose of examining the relationship between smoking, perceived stress and vulnerability factors, and furthermore suggesting interventions to reduce excessive smoking and prevent nicotine dependency effectively, the questionnaires of perceived stress(stressful experiences), ways of stress coping(passive and active copings), smoking motives, social influence, age, amounts of smoking, and nicotine dependency were administered to smokers among medical students in Chosun university(n=186). 1) As a result of classifying smokers by the types of smoking, the most was a type of smokers to reduce negative emotions and the next in order were addictive smokers, smoker for stimulation, smoker for pleasure, etc. 2) The effects of motive, age, and active coping style were significant, but the effects of perceived stress, passive coping style, and social influence were not significant in average amount of daily smoking. 3) The effects of motive, social influence, and age were significant, but the effects of perceived stress, passive and active coping styles were not significant in the degree of nicotine dependency. To summarize, it is concluded that there were a lot of people who smoke to solve negative emotions, but the direct effects of perceived stress and passive coping style on both average amounts of daily smoking and the degree of nicotine dependency were not significant. On the other hand, motive, age, active coping style, and social influence were proved to be more important variables than the others in explaining college students' smoking.

This study examined the effects of response-facilitating factors(Food-related Knowledge, Response-Efficacy, and Self-Efficacy) and response-inhibiting factors(Severity, Vulnerability, and Consumer Stress) on the consumer' behavior intention based on protection motivation theory, which explains the behavioral change to protect oneself. This study was conducted to reduce the customers' concerns regarding food safety accidents and introduce ways to make them more interested in food safety. A sample of 225 adults over 19 years of age was collected in February 2018 through a self-administered questionnaire. The results of the cognitive mediation process of protective motivation theory showed that the consumers' knowledge and self-efficacy which are response-facilitating factors, positively influence the behavioral intention. Severity and consumer stress were response-inhibiting factors. On the other hand, response-efficacy, which is a response-facilitating factor, and vulnerability, which is a response-inhibiting factor, did not influence the behavioral intention. Therefore, severity and consumer stress are response-inhibiting factors. The results were analyzed as a result of a behavioral change to protect oneself from food safety accidents. The applicability of the theory of protection motivation on the topic of food safety was also confirmed.

Obesity could cause immune-physiological disorders in fish. Yet, little is known about the impact of obesity on stress and histological responses. This study aimed to determine histological and physiological changes in and vulnerability of overfeeding-induced obese rainbow trout Oncorhynchus mykiss exposed to stress condition. Control, intermediate and overfed groups were fed at 1.5, 2.5 and 3.09% of their body weight per day, respectively, for eight weeks. Weight gain, body mass index, hepatosomatic index and serological parameters, and histology of liver were measured in five fish from each group at week 0, 2, 4, and 8. At week 8, 20 fish from each group were exposed to heat stress by increasing water temperature at a rate of 3℃ per day from 15 to 25℃ and maintaining the final temperature for 10 days. Overall, overfed fish showed significantly higher weight gain, body mass index, and serological parameters than those of fish in the other groups. Fish in the overfed and intermediate groups displayed multifocal infiltration of inflammatory cells in hepatic parenchyma. Mortality rate and serological parameters of fish in the overfed group exposed to heat stress were significantly higher than those of fish in the other groups, indicating increased vulnerability to environmental stress.
