The purpose of this study was to investigate the identified groups depend on the relationship of smartphone overdependence and adolescents' perception of smartphone overdependence itself. The study also explored gender positions in classified groups and the relationship between irrational perception of smartphone and positive emotion while smartphone usage. The participants to the study were 2,033 adolescents, aged between 10 and 19 from a smartphone overdependence survey of the National Information Society Agency. As a result of the qui-square analysis and MANOVA, four groups were classified depend on perception of smartphone overdependence and related smartphone overdependence behaviors. Second, gender did not show any differences in groups. Third, adolescents with lower perception in smartphone overdependence showed lower perception of smartphone usage compared to other adolescents in three groups. Fourth, adolescents with constructive perception in smartphone overdependence reported positive emotions. The results of this study suggest that it is necessary to understand adolescents' smartphone overdependence and look together with the irrational perception of smartphone.

This study was to examine the effects of risk characteristic and risk perception on risk severity of natural disaster. The findings showed that the risk severity of natural disaster were classified into geographical disaster, storm and flood damage, drought damage. Typhoon among storm and flood damage showed high scores on risk severity of natural disaster. Moreover participants showed high scores on unfamiliar, undiscoverable, and unknown by scientific knowledge among risk characteristic of natural disaster. Second, risk characteristic was significantly correlated to risk perception. Third, risk characteristic influenced positively on risk severity of natural disaster. Especially, risk characteristic had great effect on storm and flood damage among natural disaster. Fourth, risk perception influenced positively on risk severity of natural disaster. Especially, risk perception had great effect on storm and flood damage among natural disaster.

This study analyzes traffic accident severity of old age drivers in fourteen cities and counties of Jeonbuk Province. It is assumed that traffic accident effecting factors have two staged structure by personal and driving environment and urban characteristics. Multilevel Analysis Model is used under the assumption of hierarchical characteristics to analyze factors effecting severity. As the driver's age increases after sixty-five years old, accident damages become severe. The drunk driving is likely to make traffic accident damage more severer. The number of fatal accident by old age drivers is about three time more than by no old age drivers. Old age drivers have higher number of night traffic accidents but severer ones in daytime. Old age drivers show the higher number of traffic accidents but severer ones in fine weather. Wet road surface also influences damage severity and especially old age drivers show higher serious damage and fatal than no old drivers.

With the development of artificial intelligence(AI), the jobs of many human experts are threatened, and this also applies to the legal profession. This study attempted to investigate whether AI can actually replace humans in the legal profession, especially the role of judges making final judgments. For this purpose, from the perspective of uniqueness neglect, this study was conducted to confirm the effect of involvement and the severity on acceptance of the judgment made by the AI judge (Experiment 1) and the AI jury (Experiment 2). The involvement was manipulated as if the subject who was sentenced for committing a crime was his or her family (mother, father) or stranger, and the severity was manipulated by the extent of the damage, the perception of the crime, and the number of applied crimes. In Experiment 1, the interactive effect of involvement and severity was found. Specifically, when the involvement was low, the acceptance of AI judges was higher in high severity (vs. low severity). Conversely, when the involvement was high, the acceptance of AI judges was higher in low severity (vs. high severity). The same interactions as in Experiment 1 occurred in Experiment 2. Specifically, when the involvement was low, a larger number of AI jury members were allocated in high severity (vs. low severity). On the other hand, when the involvement was high, the number of AI juries increased in low severity (vs. high severity). This study has implications in that it is the first experimental study in Korea on artificial intelligence legal judgment and that it presents the prospects for the jobs of legal experts.

문제의 심각성은 단순한 프로그램의 수정으로 될 수 없다는 점이고, 현재까지 구축된 관련 데이타베이스를 동시에 수정하지 않으면 안 된다는 점이며, 가동중인 정보 시스템을 정지시키고 이러한 문제를 동시 다발적으로 해결할 수 있다면 문제는 간단하게 의외로 쉽게 해결될 수 있을 것이지만 현실은 이를 허용하지 않는다는 점에서 2000년 문제의 심각성을 인식하여야 한다.

문제해결을 위해서는 제일 중요한 것이 사항의 심각성을 빨리 인식해야 한다는 것과 시간 관리를 철저히 해야 한다는 것이다. 심각성을 인식하는 순간부터 2000년 이전까지의 어떤 방법으로 해결할것인가, 어떤 툴을 이용해서 해결할거라는 생각을 버리고 우리 조직이 이런 문제를 해결하기 위해서 문제를 해결하기 위한 과정에 대한 계획을 세우고, 과정을 진행하면서도 피드백을 통해서 철저하게 관리를 해야 한다는 것이다.

As the development of service marketing, research on service failure has gained more and more attention. This research aims to explore factors influencing the service failure severity perception, focus on consumers' internal propensity, ZOT(zone of tolerance) about service and comparison with other consumers in service failure situation. According to study results, it revealed that past experience satisfaction has negative effect on the zone of tolerance about service failure. Company image also has negative effect on the ZOT about service failure. While service importance has negative effect on the ZOT about service failure, it has positive effect on the perceive service failure severity. The ZOT about service failure has negative effect on perceived serviced failure severity. In contrast, social comparison perception level has no effect on perceived service failure severity, and negative affectivity also has no effect on that. In Conclusion, five hypothesis are accepted among seven hypothesis. This study gives important point to researchers and service providers in the service industry. For researchers, the result will be helpful them to further develop service failure and recovery framework. For service providers, the results will suggest specific guidelines for recovering the service failure. They can place emphasis on the serious point, so they can get a effective performance from the recovery strategy.

During clinical trials a researcher is frequently able to observe a disease symptom in a subject as well as a severity score for those who experienced a symptom after a fixed length of treatment. The traditional method to evaluate a decreasing trend in proportion, when there is an intrinsic order in the treatment groups (for example control and two or more treatment groups) is a Cochran-Armitage test, while the method to evaluate a decreasing trend in continuous non-normal data is a Jonckheere-Tersptra test. The Cochran-Armitage test emphasizes the dichotomous data of symptom occurrence and the Jonckheere-Tersptra test emphasizes the continuous non-normal data of severity symptom scores. In this paper we propose new test statistics that consider the combined evidence from a symptom occurrence and disease severity score. We illustrate these methods with example data of schizophrenic inpatients that demonstrated antipsychotic-drug induced constipation. A small-scale simulation is conducted to compare the new trend tests with other trend tests.

해상의 특수성에 따른 한계 때문에 특히 여객선의 해양 사고에서 골든타임 준수는 대형 참사를 막을 수 있는 중요한 요소이다. 본 연구에서는 여객선의 해양사고 발생 시 골든타임을 준수하기 위하여 항해사가 대피항로를 선정하는데 의사결정을 지원할 수 있는 알고리즘을 구축하고자 한다. 사고의 심각성 정도에 따라 대응할 수 있는 방법이 다르기 때문에 사고의 심각성을 3단계로 구분하였고, 운항자 11명의 인터뷰 조사를 통하여 대피항로 선정 알고리즘을 고안하였다. 또한 국내 여객선 사고 사례에 적용하여 그 실용성을 확인하고, 보완점을 도출하였다. 이러한 대피항로 선정 지원 알고리즘은 사고 발생 시 항해사가 올바른 의사결정을 할 수 있도록 지원함으로써 여객선 사고의 인명피해를 감소시키는데 기여할 수 있을 것이다.
