Mountainous areas are 64% in Korea and are allowed to be used by the permission standards of the "Mountainous Districts Management Act". In the act, slope and elevation criteria are defined to regulate the use of vulnerable land parcels to disaster. However, the standards cannot represent topographical variation in a land parcel such as terrain relief. Therefore, the applicability of slope type standard as a permission standard was tested using Catena in this study. Based on the theoretical grounds, two slope types were analyzed as 'risky slope' with disaster risk. The slope types of landslides in Namwon City were analyzed that 'risky slope' types were distributed about 57%. This study analyzed the forestland parcels that could be used when applying the current permission standards and the parcels that were already used in Namwon City. The ratio of the 'risky slope' in the parcels was more than 50%. Therefore, it is necessary to prevent the mountain development in 'risky slope' by establishing permission standard related to slope types. In addition, this study suggested the ratio of 'risky slope' in the parcel for the permission standard for forestland use conversion.

The discussion of "new risks" in the field of social policy started to gain attention in the late 1990s and it is commonly argued that new risks are provoked by deindustrialization and/or globalization being more concentrated among the young, women and low skilled individuals. This study commences its inquiry with a conceptualization of labour market risk in an attempt to critically rethink the argument of new risk. A reevaluation of the concept is followed by an empirical investigation on the different types of risks and their changes by different degree. Eight-teen countries are selected in order to provide a comparative account to understand new risk. These are comparatively analyzed using the fuzzy-set ideal type approach to discover different types of social risks and to measure degrees of changes in relation to social risk. In sum, this paper aims to answer: what is new risk? and how do the characteristic of labour market risks differ in different post-industrial countries? The findings suggest that the types of risk are diverse and the speed or the directions of shift are also diverse.

This study was a comparative analysis by youth's internet addiction types. Distribution of internet addiction types, relative influence of risk and protective factors in each addiction type, and common and different risk and protective factors among the internet addiction types were investigated. And, the level of youth's mental health and the effect of internet to youth's mental health were identified. A total of 1,830 youth were surveyed, and the findings were as below: Firstly, 62.3% of the surveyed youth were addicted to internet. In detail, 15.9% had internet game addiction and 10.9% had internet sex addiction. Secondly, in all types of internet addiction, the risk factors gave severer influence than the protective factors did, and the protective factors gave compensation effect to each type of addiction. Thirdly, among the internet addiction types, the common risk factors were depression, aggression, parents' control, and friends' influence, while the protective factor was self control. Among the internet addiction types, a different risk factor was PC access, and the different protective factors included self-efficacy, teacher's support, friend's support, and parents' relationship. Fourthly, in all the three addiction pattern, the addicted adolescents had experienced more psychological symptoms than general internet users had. Finally, in the aspects of psychiatric symptoms, sex addiction gave the worst negative effect, and then game addiction, and internet addiction came in order. And the adolescents who had the higher degree of addiction were more likely to experience psychiatric symptoms.

The current study aimed to explore the suicidal behaviors and risk factors of completed suicides using psychological autopsy and use them as index variables to classify suicidal types. In addition, this study looked into the influential factors that affect each suicidal type. related to suicidal behaviors and suicidal risk factors by psychological autopsy. In addiction, the distinctions among the classes were analyzed. For this, psychological autopsies were conducted on the families and the close ones of 128 completed suicides. Then, the index variables were finally chosen for classifying suicidal types. The selected index variables for suicidal risk factors were mental disorders, suicide/self-harm, significant changes in physical appearance, marital conflict, adjustment and relationship issues at work/school, unemployment/layoff, jobless status and serious financial problems. The selected index variables for suicidal behaviors were expressing their suicidal attempts, writing suicidal notes, asking for help, the time/place/method of suicidal behavior, past suicidal/self-harm experience and the first person who witnessed the suicide. The Latent Class Analysis(LCA) and the 3-step method were used for classifying suicidal types. Then external variables(financial changes, cohabitation, existence of stressors, changes in stress level or relationships and family members with mental disorder/alchohol problems/ physical disorders, and work/school stisfaction) were applied for distinguishing classes. As a result, 5 classes(financial problems, adjustment problems, complex problems, psychiatric problems, and response to event[s]) were revealed on suicidal behaviors and 3 classes(residence- suicidal attempt- found by family, nonresidence- nonsuicidal attempt- found by acquaintances, residence- nonsuicidal attempt- found by family) were presented on suicidal risk factors. External variables such as gender, marital status, cohabitation, changes in relationships significantly differentiated among the 3 classes. Especially, class 3(residence- nonsuicidal attempt- found by family) tended to cohabit with others, were married, and had a significantly high level of interpersonal conflicts. When comparing the 5 classes of suicidal risk factors, auxiliary variables such as economic changes, cohabitation, stress, relationship changes, and family-related problems, and school/work satisfaction significantly differentiated the 5 classes. Especially class 3 (complex problems) experienced comparatively less family-related problems, but showed an aggravating level of personal stress. Suicial prevention strategies should be provided considering the characteristics of each class and the influential factors.

세계무역센터를 대상으로 발생한 9.11.테러 이후 세계 테러 동향은 하드타겟에서 경성타겟으로 점차 변화하고 있다. 경성타겟으로 목표 변화는 테러리스트의 접근성, 대상의 상징성, 미디어 집중성을 고루 갖추고 있어, 테러리스트들의 의사 전달이 용이하기 때문이다. 경성타겟으로 변화와 함께 미디어를 활용한 테러 교육으로 자생테러(외로운 늑대)도 증가하고 있다. 2022년 7월 8일, 일본의 다중이용시설인 나라현 야마토사이다이지 역에서 총기테러 사건이 발생하였다. 야마가미 데스야가 자생테러범은 개조한 사제 총기를 일본 전 총리 아베를 향해 발포하여 과다출혈로 사망에 이르게 하였다. 위 사례는 세계 테러 동향의 변화를 반영한 사건으로, 경성타겟을 목표로 한 자생테러 형태를 보여주고 있다. 본 연구에서는 국내 다중이용시설 테러 발생 시 우선적으로 고려해야하는 고위험 테러유형을 도출하고자, 우리나라와 국가 경쟁력이 비슷한 G7국가의 다중이용시설을 대상으로 발생한 테러사례를 통계적으로 분석하여 테러유형별 위험도를 도출하였으며, 다중이용시설을 대상으로 자행되는 고위혐 테러유형의 위협을 차단하기 위한 테러안전관리 대책의 개선사항을 제언하고 있다.

One of the important prudential regulations is the capital regulation. The current domestic and international capital regulation sets the minimum capital requirement according to the size of risk which is the simple sum of market risk and credit risk. However the portfolio theory suggests that, due to the effect of diversification, the total risk is less than the summation of market and credit risk. This paper investigates and does empirical test to verify the diversification effect in measuring financial firm's integrated risk. We verify the diversification effect between the market risk and credit risk. This paper's contribution is to present the empirical evidence that, considering the relationship between market and credit risk, the integrated risk is less than sum of them. This implication is that the surplus capital may be used for the other purposes, therefore enhancing capital allocation efficiency in view of society as a whole.
