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.

Recently, in the field of open domain natural language question answering, multi-task, multi-hop question answering has been studied extensively. In this paper, we propose a novel deep neural network model using hierarchical graphs to answer effectively such multi-task, multi-hop questions. The proposed model extracts different levels of contextual information from multiple paragraphs using hierarchical graphs and graph neural networks, and then utilize them to predict answer type, supporting sentences and answer spans simultaneously. Conducting experiments with the HotpotQA benchmark dataset, we show high performance and positive effects of the proposed model.

Recently fast innovation of Internet technology causes lot of application to change into web application and requirement for the inter-operable communication among various systems are increased rapidly. These trends are part of changes which is caused by ubiquitous world and it is just beginning of huge waves that is required to fit and change under the ubiquitous environments. This thesis is focused on the Design and Implementation of Layer Structured Components which can be interfaced effectively for the Material Management System under the Heterogeneous Client Server Environments. The key points to do that kinds of affairs are using XML web services that can communicate thru systems and also using independent layered components for the enforcement of reusability and inter-operability. For the various type of testing of implementation, we used RFID System, PDA, Desktop Systems and confirmed the normal operation without concerning the type of client system and platforms. The Components proposed in this thesis could be reused effectively in case of developing similar applications.

Terms collected from theological dictionaries in English and the Scripture are used in order to construct conceptual relationships of theological thesaurus. Using the terms, equivalence relationships, hierarchical relationships, and associative relationships as the basic relationships in thesaurus are constructed. In equivalence relationships, Hebrew, Greek, and Latin terms are included as descriptors and in hierarchical relationships, generic, instance, whole-part, and polyhierarchical relationships are constructed. Also, there is no big difference in the kinds of conceptual relationships between this theological thesaurus and the thesauri of other subjects. Examples of Biblical Theology are showed. Because Biblical Theology has a strong point to view the Scripture and Protestantism on comprehensive perspective. In this context, one of the main feature in the theological thesaurus is that there are a lot of the allegorical terms. Typology, which is the core structure causes this result.

The purpose of this study is to identify determinants for preferred funeral methods depending on socio-economic characteristics. In South Korea, the Act on Funeral Services, Etc. categorizes funeral methods into burial, inurnment, and natural burial. This study empirically analyzes how and what socio-economic characteristics affect choices among these three categories. Data is collected from Social Survey 2017 and funeral facilities in the country. The data to be analyzed is developed in terms of a hierarchy which puts the burial and cremation methods in an upper class and the inurnment and natural burial methods in a lower class. Based on this data, a nested logit model is employed to conduct empirical analysis. The analysis indicates that those characteristics that have a statistically significant influence on preferred methods include gender, age, householder, marriage, satisfaction with life, class awareness, monthly income, housing type, housing tenure type, and living in city area. Each variable's modulus of calculated direct and cross elasticity need to be used to analyze the outcome of a nested logit model. In this study, the modulus of direct and cross elasticity are determined for the significant variables. The calculated direct elasticity is applied to analyze the likelihood of choosing each funeral method when there are changes in the significant variables. When a particular method has been selected, on the other hand, the cross elasticity is utilized to analyze changes to the likelihood of choosing the other methods. One of the most notable results is related to natural burial. In order to meet the demand for natural burial, it is necessary to provide more burial sites and raise awareness of natural burial. This will facilitate the efficient use of national territorial space.

Within twenty years, Permanent Affordable Housing provided for people's security of housing in late 1980's yields the principles of equity with tenant's in new one supplied, thus being confronted by the requirements that existing welfare service for tenants should be improved. Reflecting on these, this study means to prepare the basic data for the welfare policy as applying welfare service types on basis of housing locational characteristics, tenants tier compared with welfare service needs of permanent affordable housing tenants. For achieving this aim, the range and mixed use mechanism of welfare service are investigated as reviewing the related research and findings. Based on this investigation, 7 types of welfare service(Independence, Half-support, Child care, Juvenile, Self-support, Social-mix, and Single household) are established. On the analysis of survey, the welfare service needs are investigated as grouping with locational characteristics and survey target. In addition, the welfare service types are reorganized by analysis of tenant's demographic and locational characteristic on each housing and are compared with tenants needs. Although, the demographic of permanent affordable housing generally shows that the tenants are constituted with aged people, the housing with high ratio of children and juvenile can be applied with Child Care type and Juvenile type. As a result of comparison, the ratio of independence type, juvenile type, and single household type are more on the large housing and housing on metropolitan area, and the ratio of half-support type and child care type are more on the small housing and housing on small city area.

주택부족 문제의 효율적 해결방안의 하나로 보급되기 시작한 아파트는 다양한 문제의 표출에도 불구하고 '좁은 땅에 많은 주택 공급'이라는 한국 현실에 가장 적합한 주거유형으로 정착되고 있다. 본 연구는 아파트를 비롯한 여러 유형의 집합주거가 어떤 계층의 가족에 의해 선호되고, 나아가 이상적인 주거유형 규범으로 인식되고 있는지 규명하기 위한 것이다. 모델에 포함된 변인중 가장의 연령과 학력은 현재 거주하는 주거유형 및 집합주거 선호에 유의적인 영향을 미치는 것으로 나타났다. 또한 현재 집합주거에 거주하는 가정일수록 높은 집합주거 선호를 보였다. 집합주거 규범에 관한 분석에서는 집합주거 선호 변인만 유의적인 영향을 주어, 집합주거를 선호하는 가정일수록 이를 한국 사회의 주거유형규범으로 생각하는 경향이 많은 것으로 해석할 수 있다.
