Recently, interest in ChatGPT has been increasing. This study investigated the factors influencing the satisfaction of users using ChatGPT service, a chatbot system based on artificial intelligence technology. This paper empirically analyzed causality between the four major factors of service quality, system quality, information quality, and security as independent variables and user satisfaction of ChatGPT as dependent variable. In addition, the mediating effect of reliability between the independent variables and user's satisfaction was analyzed. As a result of this research, except for information quality, among the quality factors, security and reliability had a positive causality with use satisfaction. Reliability played a mediating role between quality factors, security, and user satisfaction. However, among quality factors, the mediating effect of reliability between service quality and user's satisfaction was not significant. In conclusion, in order to increase user satisfaction with new technology-based services, it is important to create trust among users. The research results sought to emphasize the importance of user trust in establishing development and operation strategies for artificial intelligence systems, including ChatGPT.

이 연구는 중학생의 생명현상 관찰활동에서 과학적 흥미가 발생하는 요인을 추출하고, 추출한 요인이 과학적 흥미의 발생에 영향을 주는 정도를 검증한 것이다. 흥미발생요인을 추출하기 위해 중학교 3학년을 대상으로 4차시 분량의 관찰활동 프로그램을 투입하였고, 관찰활동에 참여한 학생 중 과학적 흥미가 높았던 학생을 대상으로 면담을 실시하였다. 면담 결과를 응답 유형별로 분류하여 21가지의 흥미발생요인을 추출하였다. 추출한 흥미발생요인은 크게 관찰대상의 특성, 관찰활동의 특성, 관찰결과의 특성, 관찰자의 특성, 외적 요인의 특성 등 5가지로 범주화하였다. 이렇게 추출한 흥미발생요인이 관찰활동에서 과학적 흥미의 발생에 영향을 주는지 검증해 보았다. 우선, 추출한 흥미발생요인이 관찰활동에서 흥미의 발생에 영향을 준 정도를 확인하기 위하여 흥미발생요인 조사지를 작성하였다. 중학교 3학년을 대상으로 4차시 분량의 관찰활동 프로그램을 실시한 후 흥미발생요인 조사지를 투입하였다. 흥미발생요인 조사지의 응답 결과를 분석하여 각각의 요인이 흥미의 발생에 영향을 준 정도의 차이를 확인해 보았다. 그 결과, 추출한 21개의 요인은 과학적 흥미의 발생에 유의미한 영향을 주는 것을 확인하였다. 이 연구의 결과는 흥미롭지 않은 관찰활동에 대한 원인 분석이 가능하며 흥미로운 관찰활동 프로그램을 개발하는데 매우 중요한 역할을 할 것이다.

본 연구에서는 PISA 검사결과를 토대로 온실효과에 대하여 우리나라의 만 15세 학생들이 지니고 있는 전형적인 학생개념의 유형을 분석하였다. 온실효과에 대한 기존 선행연구에서 밝혀진 학생들의 대안적인 개념에 비추어 볼 때, 현재 우리나라의 만15세 학생들의 온실효과에 대한 이해 수준을 온실효과의 자연적 요인과 인위적 요인으로 나누어 분석하고, 온실 효과를 초래한 원인에 대한 학생들의 오개념 유형을 살펴보았다. 이산화탄소 이외에 지구의 온도 상승에 기여하는 요인들 우리나라 학생들은 프레온 가스, 매연, 수증기, 메탄 등을 지적하였다. 또한 많은 학생들이 온실효과와 오존층 파괴가 인과관계를 지니고 있는 것으로 파악하고 있음을 알 수 있었다. 과학과 교수 학습에 얻을 수 있는 시사점을 도출하였다.

This study attempted to investigate the effect of foodservice quality perception on residence satisfaction of silver town residents. Through an extensive literature review, the questionnaire was developed and distributed to senior residents in 'A' silver town located in Gyeonggi-Do. Out of 254 questionnaires administered, a total of 212 completed questionnaires were returned, yielding a response rate of 83.5%. The results showed that there was a meaningful correlation between perception on foodservice quality and residence satisfaction. Among foodservice quality factors, reliability and comfort were the most important factors affecting residence satisfaction. Considering the effect of reliability and comfort factors on residence satisfaction, it is important to make a strategy to build up these factors in foodservice operation of silver town.

The purposes of this study were to investigate the factors related to conspicuous consumption and the effect of materialism and reference group on the conspicuous consumption. The data used in this study included 287 homemakers living in Mokpo and Kwangju,. Statistics used for data analysis were Means Frequencies One-Way Anova and Multiple Regression Analysis. The findings were as follows: 1) The factors related to conspicuous consumption were educational level of wife educational level of husband job of husband and subjective level of living 2) The factors related to materialism were age of wife and subjective level of living 3) The factors related to reference group were age of wife educational level of husband job of husband and subjective level of living 4) Materialism and reference group had positive effects on conspicuous consumption 5) The effect of reference group was the most influencial factor.

This study was focused to find how each factors effect on the biological nitrification in wastewater treatment under high ammonia nitrogen concentration. Batch reactors in aerobic conditions were used to test the treatment efficiency of mixed liquor, nightsoil and piggery wastewater. The results are summeried as follows; Initial ammonia nitrogen concentration and pH were the direct influencing factors of nitrite build-up. More than 250 mg NH$_{4}$$^{+}$ - N/L in initial concentration built up nitrite and then the inhibition rate to Nitrobacter was above 70 percentage. And maximum nitritation rate was showed at pH 8.3 and nitrification could be completely achieved by pH control. Temperature and dissolved oxygen were the indirect influencing factors of nitrite build-up. These were a great effect on the activity of nitrifying microbes and ammonia nitrogen removal. Maximum nitritation rate was showed at 30 $\circ $C. The effect of DO concentration was negligible at more than 3 mg/L.

Finding the factors to affect the success of the business web sites is critical to enhance their competitiveness. This paper categorizes these factors into 4 quality measures: system, information, service and entertainment. The success is measured via user's satisfaction and loyalty. It surveys 474 Internet users to explore the effect of the quality measures on web site success. We confirm the causal effect of quality factors on users' satisfaction and loyalty. Furthermore, a comparative study is performed for web site types, such as finance, e-commerce(shopping mall), and entertainment. We note that the effect differs in web site types.

Two-level fractional factorial designs are widely used when many factors are considered. When two-level fractional factorial designs are used, some effects are confounded with each other. To break the confounding between effects, we can use fractional factorial designs, called fold-over designs, in which certain signs in the design generators are switched. In this paper, optimal fold-over designs with four-level quantitative and two-level factors are presented for (1) the initial designs without curvature effect and (2) those with curvature effect. Optimal fold-over design tables are provided for 8-run, 16-run, and 32-run experiments.

본 연구는 다문화청소년의 개인·정서·부모·사회·환경적 요인이 진로미결정에 미치는 영향 요인을 파악하는 것을 목적으로 한다. 조사대상자는 현재 고등학교에 재학 중이며 아버지가 한국인인 다문화청소년 1,146명을 다문화청소년패널(MAPS) 7차 자료에서 추출해 다중회귀분석으로 검증했다. 연구결과는 첫째, 다문화청소년의 개인 요인인 자아존중감과 사회·환경적 요인인 학교생활적응 및 다문화 수용이 진로미결정에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 정서적 요인으로 우울증과 부모요인인 방임이 진로미결정에 부적인 영향을 미치는 것을 확인하였다. 하지만 부모-자녀 의사소통은 진로미결정에 영향을 미치지 않는 것으로 확인되었다. 이와같은 연구결과를 토대로 다문화청소년의 진로 미결정을 사전에 예방하고 진로미결정을 위한 기초자료를 제공했다는 점에서 의의가 있다.

The safety of the ship manoeuver is dependent not only on the inherent characteristics of the ship itself and environmental conditions, but also on the skill and experience of the ship operator. As the ship operator's judgement is related to his experience and skill, based on outside information, piloted controllability also depends upon the effectiveness, accuracy and reliability of various information which is obtainable from navigational equipments and aids to navigation that are available to the ship ope-rator. Although these factors, human factors and informational factors, have been pointed out as major factors which affect the controllability of a ship, there was no a comprehensive examination on the effect of these two factors. In this thesis, therefore, an attempt was made to examine whether or not there is clear indication that these two factors affect the controllability of a ship in reality. Experiments were conducted using the port design simulator of the Korea Maritime University.
