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.

In investigating missing persons cases, the focus is on strengthening the efficiency of detectives' work in investigating missing persons cases. Disappearance cases are seen as a problem that directly affects social safety and individual well-being. The research has the following structure. The introduction presents the necessity, scope, and methodology of the study. Next, we analyze the definition, causes, types and actual conditions of disappearance cases. In terms of problems in the process of handling missing persons cases, the initial response process, problems in the response of related agencies after reporting, problems due to the prolongation of the case, and problems due to legal restrictions are analyzed. In the plan to improve the work efficiency of detectives for disappearance cases, the revitalization of public interest investigation networks, strengthening of capacity related to disappearance case investigation, professional public interest detective certification system, and establishment of exception provisions for detective activities are discussed. In the conclusion, we present what is necessary for the activities of public interest detectives specializing in missing persons cases.

The purpose of this study is to propose a different classification method for keeping a record of cases. After proving that criminal case files should be counted as one type of case files, based on their characteristics and characteristics, this research analyzes the current process of criminal case filling at Public Prosecutor's Office to point out some problems. This study suggests a new classification system: at first, each case gets classified based on a case: secondary, the data gets further assorted by the chronological procedures. The classification approach, which is adopted from MoReq 2's Workflow method, is more adjustable to the new electronic filing system.

People observe lots of events around the environment and we can easily recognize the nature of an event from the resulting optic flow. The questions are how do people recognize events and what is the information in the optic flow that enables observers to recognize events. Motor theorists claim that human observers exhibit special sensitivity when perceiving events like speech or biological motion, because we both produce and perceive those events. However, direct perception theorists suggested that speech or biological motion is not special from the perception of all other kinds of event. The purpose of this review article is to address this controversy to critique the motor theory and to describe a direct realist approach to event perception. It is important to understand the fundamental information of how human perceive event perception for the convergence on robotics.

Recurrent event data occurs when a subject experiences same type of event repeatedly and is found in various areas such as the social sciences, Economics, medicine and public health. To analyze recurrent event data either a total time or a gap time is adopted according to research interest. In this paper, we analyze recurrent event data with incomplete observation gap using a gap time scale. That is, some subjects leave temporarily from a study and return after a while. But it is not available when the observation gaps terminate. We adopt an interval censoring mechanism for estimating the termination time. Furthermore, to model the association among gap times of a subject, a frailty effect is incorporated into a model. Programs included in Survival package of R program are implemented to estimate the covariate effect as well as the variance of frailty effect. YTOP (Young Traffic Offenders Program) data is analyzed with both proportional hazard model and a weibull regression model.

This study analyzed characteristics of which a teacher asked questions in an instruction on the probability that event A and event B occur. The aim of this study based on the analysis was to deduce implications in terms of the various means which would enhance middle school students' understanding about the probability and assist teachers in designing instructions on the mathematics contents. To achieve this goal, this research firstly reviewed Morgan & Saxon(2006) which offers one classification of questioning that identifies a general intention for each category. Secondly, this study examined previous literature on teaching and learning the probability that event A and event B occur in order to identify didactical issues to teach the mathematics contents. Therefore, this study probed the questions of the instruction in the light of the framework descriptors from Morgan & Saxon(2006) and the issues to teach the probability that event A and event B occur. This research inspires the elaboration of what features have with regard to effective questioning in teaching mathematics through the analyzing process and additionally the elucidation of essential matters related to mathematics education on the basis of the analyzed results.

The sinking of the Sewol ferry has not only induced an intense conflict in Korean society but also been developed into a sociopolitical issue. This paper divides this accident into five stages and examines the records produced at each stage. The Sewolho Citizen Archive Network and the Ansan Citizen Record Committee began the archiving of Sewol and created the 416 Archives. The records of Sewol are social and political records that hold envidencial and historical value. They can be used to rebuild and recover the wounded community as well as to investigate the truth behind the case. Accident archiving collects materials different to the ones which public archiving does, allowing people to view the incident from a different standpoint. It is also characterized as an archiving of the current issue, social movement and regional community. Accident archiving is a method which ensures credibility and impartiality in memory. In light of Sewol archives, accident archiving can contribute to form mature democracy.

일반적으로 기업결합사건에서 사실확인의 단계에서 이루어지는 관련시장의 획적은 경쟁제한성이라는 위법성판단 여부를 좌우할수 있는 중요한 문제로서 다루어진다. 하지만 이러한 관련시장의 확정은 동시에 기업결합심사에 있어서 난해한 부분이기도 하다. 그런 점에서 본 고에서는 기업결합사건에서 시장획정이 문제된 비교적 최근의 사건인 1997년 연방항소법원 판결을 소개하기로 한다. 본 건은 미 법무부가 기업결합안에 대해 제소한 사건을 미 연방 제11항소법원이 기각한 판결에 관한 것이다. 이 사건에서 미 법무부는 시장내의 3사업자들 가운데 2사업자간에 이루어진 기업결합안을 클레이튼법 위반으로 문제삼았는데, 항소법원은 법무부가 관련시장을 적절히 획정하지 못했다는 이유로 본 건을 기각하였다. 법무부는 관련시장의 규모를 확인하지 못하였으며 따라서 경쟁상품들을 적절히 고려하지 못하였다는 것이 그 이유였다.

본 연구는 우리나라의 실제 일별 주식수익률 자료를 이용한 시뮬레이션을 통해 우리나라 주식시장에 가장 적합한 사건연구방법론을 도출하고자 하였다. 이를 위해, 1980년에서부터 1995년까지 우리나라 주식시장에 상장된 675개 주식을 대상으로 무작위 복원추출 방법에 의해 50개의 개별주식으로 구성된 250개 표본을 선정하였다. 이들 250개 표본을 이용하여 시뮬레이션 기법에 의해 다양한 사건연구 모형의 통계적 오류와 검정력에 미치는 영향을 종합적으로 분석하였다. 시뮬레이션 실험 결과에 의하면, 먼저 사건일을 정확히 포착할 수 있는 경우에는 산업별주가지수를 시장지수로 선택한 시장모형 혹은 시장조정모형으로 초과수익률을 측정하고, 횡단면 독립성을 가정한 검정법이 가장 우수한 사건연구방법으로 나타났다. 한편, 사건일을 정확하게 포착할 수 없는 경우에는, 동일가중지수를 시장지수로 선택한 시장모형 혹은 시장조정모형으로 초과수익률을 측정하고, 횡단면 독립성을 가정한 검정법이 가장 적합한 모형으로 나타났다. 그리고, 사건일 집중현상으로 인한 제1종 오류를 감소시키는 데에는 개별주식의 초과수익률 간의 횡단면 독립성을 가정한 검정법보다는 횡단면 중속성을 조정한 검정법을 사용하는 것이 더욱 효과적이다.

운수 회사의 사업장 소재지나 이 사건 차량의 차고지 및 원고의 주거지 관계에 비추어 원고가 이 사건 차량 이외에 청주나 송탄사료공장까지 출 퇴근하는 방법이 있었다고 보이지 않고, 그에 따라 원고의 입사 당시 사업주가 이 사건 차량을 원고의 주거지 부근에 주차한 후 이를 이용하여 청주나 송탄사료공장으로 가서 사료를 공급받아 업무를 수행하도록 용인하였던 점, 그에 따라 이 사건 차량에 대한 관리 이용권이 전적으로 원고에게 전담되어 있었고, 원고의 주된 업무가 빈 화물차량을 운전하여 사료공장으로 가서 사료를 공급받은 후 각 양계농장에 사료를 운반 배송하는 업무로 이러한 업무내용이나 근무형태 등에 비추어 원고가 화물차에 탑승하여 운전을 개시하는 때로부터는 업무수행이 시작되어 사업주의 지배 관리하에 있다고 보이는 점(원고가 자택에서 이 사건 차량에 도착할 때까지가 출근에 해당하고, 그 이후 차량에 탑승한 이후에는 바로 업무의 개시가 있었다고 할 것이다) 등에 비추어 보면, 원고가 재해 당일 새벽 청주사료공장으로 가기 위하여 이 사건 차량을 운전하다가 발생한 이 사건 재해는 업무상 재해라고 봄이 상당하다.
