고대 천문기록을 연구하는 과정에서 기록의 사실 여부와 함께 천문기록에 영향을 미치는 요소를 확인하는 것은 중요하다. 본 연구에서는 고대의 천문기록 중에서 관측 빈도수가 높은 유성과 유성우 기록을 통해 이들의 분포와 역사적 환경 요소와의 관련성을 알아보았다. 유성과 유성우 기록을 분석한 선행연구에 의하면 한국과 중국 일본의 고대 유성과 유성우 기록은 잘 알려진 주기 유성우의 특성을 잘 보여준다. 그러나 인접한 세 나라의 관측 기록은 시대별로 일부 다른 분포를 보이는데 이러한 이유를 알아보기 위해 세 나라의 역사적 환경과 천문기록 분포와의 상관관계를 조사하였다. 본 연구에서는 1200년부터 1700년까지 500년 동안의 왕조-왕위교체, 외부침략, 내란과 같은 역사 사건을 조사하여 중요도에 따라 세 등급으로 나누고 이들을 유성과 유성우 기록 분포와 비교하였다. 연구 결과, 한국과 중국 일본의 고대 유성과 유성우의 기록 분포와 역사적 사건과는 서로 관련성이 없는 것으로 나타났다. 이것은 세 나라의 고대 천문관측 기록이 정치적 사건의 영향을 받지 않았음을 의미한다. 고대 천문기록을 분석할 경우 역사적 사건이나 왕위교체 등의 사회적 영향보다는 시대별 천문기록의 분포개수를 고려한 가중치가 중요하게 고려되어야 할 것이다.

In the present study, we collected the information of the 18 major food safety incidents and conducted a delphi survey with 10 experts to analyze the effect of difference between terms used in reporting of the major food safety incidents on risk communication. In the result of the analysis of information from the major food safety incidents, discord of terms used from government, local government, media and consumer groups had a tremendous effect on the socioeconomic losses and caused the expansion of the incidents. The survey with 10 experts showed that there was a high correlation between the difference in ripple effect of reporting terms and the difference in reporting terms. A correlation coefficient was 0.865. Therefore, ripple effect of incidents was significantly affected by reporting terms and we concluded that standardization of term is necessary in reporting of the food safety incidents. These results can be used as a basic material for successful risk communication among the government, enterprises and consumers.

This study compares the Korean and U.S. media's coverage of the No Gun Ri massacre, analyzing their usages of sources in the stories and explaining by the perspective of media sociology why they differed in them. For the comparison with the AP's report, we selected only the reports of the Korean media which dealt with the incident itself. It was found that most of the Korean media utilized a very small number of sources, and that they relied on the victims alone. In contrast, the AP's sources were much more numerous drawn from both the victims and offenders. As a result, the Korean media failed to ensure the 'diversity of sources' and to illuminate the whole picture of the incident, although they had started to report it far earlier than the AP. From the depth interviews with the reporters, through the framework of media sociology, it was found first at the personal level, that the difference was brought about by the divergent news evaluation. It seemed that the Korean journalists regarded the incident with relatively lower news value than their U.S. counterparts. Next, at the intra-organizational level, it was conceded, neither did the Korean new media have so flexible news collecting system, nor so murk man-power and resource as the AP, which were required for the coverage of such an incident. The Korean media had not established the convention to utilize various sources with conflicting interests. Last, at the extra-organizational level, the Korean news media's coverage was still influenced by the self-censorship mechanism due to the ideologies of 'pro-Americanism' and 'anti-communism', even though the democratization of Korean society itself enabled the sensitive incident to be dealt with eventually by the media.

There are three assassination and treatening cases in this thesis introduced as analysis data. They are shooting accidents of the U.S.A's President Reagun (1981,3.30), and the President Park Jeong Hee of South Korea(1974.8.15), assassination of the Prime Minister Lavin of Israel (1995.11.4) In March 30, 1981, there was an accident where criminal, Hinckley, fired ball cartridges right before the President Reagan got into the car to move to White House after completing the announcement of Hilton Hotel of Washington. As a result, the chest of president was shot and public information secretary and safeguard were wounded. In August, 15, pm 10:23, where the 29th 8.15 independent anniversay event was being celebrated by the people at the National theater in Jangchungdong, Seoul, the criminal Moon Sekwang fired ball cartridges, he failed to assassinate the President Park Jeong Hee of Korea, but shot the First lady Yuk Young Soo. She was wounded right part of head and died. In November 4, Saturday, pm 22:00 the Prime Minster Lavin had finished the supporting event of Middle Asia's Peace project and was taking on the car when he was killed by the criminal Amir's shooting, The accidents left very important lesson from the aspect of security analysis and it has been frequently used as a material for the education and training of safeguard organization. In Korea, as well as Presidential Security Service, national security departments have selected it as an important model for the subjects such as 'Security Analysis, 'Security Practice' and 'Security Methodology'. In the performance of security duty, security skill is the most important matter. Moreover, it has a close relationship with politics, society and culture. The purpose of this study is to analyze and reevaluate the case, which has been treated as a usual model from the aspect of security analysis, beyond its introduction. Attempted assassination of President Reagan was evaluated as a positive success example because of its rapid response of adjacent guards to evacuate Reagan, who is a guard target, within 10 seconds after the shot. When comparing it to President Kennedy Assassination of 1963, it was evaluated that guards were significantly specialized. In the study, however, it was possible to found many problems such as carelessness of guard, who is in charge of external area of event place, idle attitude for frequently used event place, confusion of wireless communication, risk of wireless security disclose, insufficient provision of compulsory record file, insufficient profiling of dangerous person and unsecured hospital and first-aid room.

This study was conducted to determine how analytic-holistic thinking style, one of the cultural characteristics, affects intentionality judgment and what role the crime typicality plays in the process. To this end, the psychological mechanism of intentionality judgment was confirmed in cases where the criminal typicality was manipulated by the moral characteristics of the crime perpetrator and victim. As a result, higher the criminal typicality lead to higher intentionality judgement. In addition, it was found that people with relatively holistic thinking style (with high causality and perception of change) judge less of the perpetrator intentionality. In particular, it was confirmed that the analytic-holistic thinking style interacts with criminal typicality and affects the intentionality judgment. Specifically, people with a holistic thinking style (high causality) judged the perpetrator to have high intentionality in typical cases, but judged in a reverse way in atypical cases. It means that, holistic thinkers, compared to analytic thinkers, strongly judge intentionality based on criminal typicality considering the moral characteristics of not only the perpetrators but also the victims. Along with the significance of this study, the relationships among analytic-holistic thinking style, criminal typicality and intentionality judgment were discussed.

Recurrent event data occurs when a subject experience the event of interest several times and has been found in biomedical studies, sociology and engineering. Several diverse approaches have been applied to analyze the recurrent events (Cook and Lawless, 2007). In this study, we analyzed the YTOP(Young Traffic Offenders Program) dataset which consists of 192 drivers with conviction dates by speeding violation and traffic rule violation. We consider a subject-specific effect, frailty, to reflect the individual's driving behavior and extend to time-varying frailty effect. Another feature of this study is about the redefinition of risk set. During the study, subject may be under suspension and this period is regarded as non-risk period. Thus the risk variables are reformatted according to suspension and termination time.

Since a homing torpedo system consists of various subsystems, organic interactions of which dictate the performance of the torpedo system, it is necessary to estimate the effects of individual subsystems in order to obtain an optimized design of the overall system. This paper attempts to gain some insight into the detection mechanism of a torpedo run, and analyze the relative importance of various parameters of a torpedo system. A database for the analysis was generated using a simulation model based on the combined discrete event and discrete time architecture. Multiple search schemes, including the snake-search method, were applied to the torpedo model, and some parameters of the torpedo were found to be stochastic. We then analyzed the effectiveness of torpedo’s detection capability according to the torpedo speed, the target speed, and the maximum detection range.

This study explored the change in keywords and topics in newspaper articles related to schizophrenia after the Gangnam murder case. The study examined newspaper articles related to schizophrenia for five years before and after the Gangnam murder case. A semantic network analysis was conducted using the NetMiner 4.4.1 program. 610 articles between 2013 and 2018 were retrieved from 8 national newsletters. The most frequent core keyword was 'treatment' before the murder case, but 'incidents' after the case. Four topics were identified: 'becoming chronic if missing the time of treatment due to prejudice', 'being curable with early treatment', 'living an ordinary life with medication', 'being indicted as a murderer while impaired by a mental disorder' before the murder case. After the case, four topics were identified: 'committing murder for delusions, not misogyny', 'medication non-adherence leads to more impulsive behavior', 'claiming leniency for criminals due to the mental impairment', 'killing the police who were mobilized to stop stabbing rampage'. These findings suggest that newspaper articles should provide accurate information about schizophrenia to reduce prejudice and stigma toward patients with schizophrenia and other forms of mental illness.

This study investigates relation of food safety incidents with climate. Therefore food safety incidents and climate data during 1999 to 2009 have been analyzed. In situ observations of monthly mean temperature, maximum temperature, minimum temperature, precipitation, and relative humidity in 60 observation stations of Korean Meteorological Administration (KMA) have been used in this study. Food safety incidents data have been constructed by searching media reports following Park's method (2009) during the same period. According to the Park's method, 729 events were collected. To analyze its relations, food safety incidents data have been classified into chemical, biological, and physical hazards. Pearson product-moment correlation coefficients have been applied to analyze the relations. The correlation of food safety incidents has negative one with precipitation (-0.48), and positive one with minimum temperature(0.45). Precipitation has been correlated with biological and physical hazards more than chemical hazard. Temperatures (mean temperature, maximum temperature, and minimum temperature) have been correlated closely with chemical hazard than others. Food safety incidents data has been interblended with human behavior factor through decision-making processes in food manufacturing, processing, and consumption phases of "farm-totable" food processing. Act in the preventing damage will be obvious if the hazard were apparent. Therefore abnormal condition could be more dangerous than that of apparent extreme events because apparent events or extreme events become one of alarm over hazards. Therefore, human behavior should be considered as one of the important factors for analysis of food safety incidents. The result of this study can be used as a better case study for food safety researches related to climate change.
