金光一,裵相俊 慶一大學校 1992 論文集 Vol.8 No.1

The cricuit of QRI(Quasi-Resonant Inverter) which is able to regulate frequency in the output voltage by the ZVS(Zero Volt Switching) was investigated. We found parameters in the circuit of QRI so that they have application to the HID(High Intensity Discharge) Lamp drive. Then we simulated that by personal computer and summarized the result of simulation.

곽민석(Kwag Min Seok),곽현규(Kwag Hyun Gyu) 학습자중심교과교육학회 2017 학습자중심교과교육연구 Vol.17 No.18

본 연구는 초등교원양성대학의 교육서비스품질과 학생만족도 및 충성도의 구조적관계를 분석하는데 그 목적이 있다. 모집단으로는 현재 전국교육대학교에 재학 중인 학생들을 선정하였고, 이 중 서울과 강원도, 충청도에 소재한 A대학교, B대학교, C 대학교 학생들을 2017년 6월 5일부터 23일까지 약 3주간 표본 집단으로 설정하여 연구를 진행하였다. 연구의 수행을 위해 설문지를 측정도구로써 사용하였으며, 총 234명의 자료를 분석하여 가설을 검증하였다. 자료 처리에는 Windows용 PASW 18.0과 AMOS 20.0 프로그램을 이용하였으며, 빈도분석, 신뢰도 분석, 확인적 요인분석, 상관관계분석, 구조방정식 모형분석을 통해 자료를 분석하였다. 본 연구의 결과는 다음과 같다. 첫째, 교육서비스품질은 학생만족도에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 교육서비스품질은 학생충성도에 영향을 미치지 않는 것으로 나타났다. 셋째, 학생만족도는 학생충성도에 긍정적인 영향을 미치는 것으로 나타났다. 마지막으로 교육서비스품질과 학생충성도 사이에서 학생만족도는 매개하는 것으로 나타났다. The current study was aimed to investigate the structural relationships among educational service quality, satisfaction, and loyalty. Data were drawn from 234 students in three different universities. PASW 18.0 for windows and AMOS 20.0 program were used for data processing. Data were analyzed using frequency analysis, reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling techniques. The results were as follows. First, educational service quality had a positive effect on satisfaction. Second, educational service quality did not affect loyalty. Third, satisfaction had a positive effect on loyalty. Lastly, satisfaction fully mediated the relationship between educational service quality and loyalty.

Bow Wave Breaking and Viscous Interaction of Stern Wave

Kwag, Seung-Hyun The Korean Society of Mechanical Engineers 2000 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.14 No.4

The bow wave breaking and the viscous interaction of stern wave are studied by simulating the free-surface flows. The Navier-Stokes equation is solved by a finite difference method in which the body-fitted coordinate system, the wall function and the triple-grid system are invoked. After validation, the calculations are extended to turbulent flows. The wave elevation at the Reynolds number of $10^4$ is much less than that at $10^6$ although the Froude number is the same. The numerical appearance of the sub-breaking waves is qualitatively supported by experimental observation. They are also applied to study the stern flow of S-103 for which extensive experimental data are available. Although the interaction between separation and the stern wave generation are not yet clear, the effects of the bow wave on the development of the boundary layer flows are concluded to be significant.

Incorporation and Production of Glucose in Lake Soyang

Kwag, No-Tae,Choi, Seung-lk,Ahnl, Te-Young,Ahn, Tae-Seok 江原大學校 附設 環境硏究所 1996 環境硏究 Vol.13 No.-

Kinetics of heterotrophic activity (glucose uptake) and extracellular enzyme activity (f-glucosidase,cellobiohydrolase) and cell numbers were measured in Lake Soyang during phytoplankton bloomdevelopment and after its breakdown Vmax for glucose was lower during Diatom bloom and that was higher after its breakdown. But the increase in f-glucosidase activity was detected in late of Diatom bloom, Glucose uptake did not associated with fglucosidase activity. The tight relation-ship between f-glucosidase and the incorporation of glucose by bacteria was not shown and significance of depolyrmerization on the incorporation of glucose in lake water are discussed.

A Study on the Influence of Choice Properties of Food Carving Decoration Lecture on Recommended Intention and Revisiting Intention

Kwag, Myung Sug,Kim, Jin Soo Kyung Hee University Management Research Institute 2020 Asia pacific journal of business review Vol.5 No.1

This paper examines the effect of the choice properties of food carving decoration lectures on the recommendation and revisiting intention. As the culinary industry grows, consumers seek not only the value of satiety through food but also the value of aesthetics. They perceived satisfaction from the taste and appearance of the food as well as the interior of the restaurant and the service. Food carving is an important means of fulfilling consumer satisfaction value which is ever-changing. This study attempts to analyze the relationship between the choice properties of food carving lectures and the course recommendation and revisiting intention. This study hypothesis was formulated and the survey was conducted on 125 respondents who had experienced food carving lectures. The reliability and validity of measurement items were verified through Cronbach's Alpha and factor analysis. As a result, all measurement items showed no abnormality. The results of the analyses are as follows. The education satisfaction, education commitment, and brand image, the choice properties of food carving decoration lecture, were found to have a positive effect on the recommendation intention. The results also showed that the education commitment and brand image of food carving decoration lectures were positively associated with revisiting intention. Lastly, the implications of these findings were suggested and for future research were discussed.

The Impact of Nudging on Retirement Savings : A Comprehensive Review and Non-Parametric Tests

Kwag, Seung Woog 한국상업교육학회 2019 상업교육연구 Vol.33 No.4

급속한 노령인구 및 기대수명의 증가는 은퇴 후 삶의 위기라는 전대미문의 사회적, 경제적 난제를 탄생시켰다. 개인들뿐만 아니라 정부도 새로운 위기에 대한 이해와 준 비가 절대 부족하다. 풍요로운 은퇴 후 삶을 위한 연금이나 저축은 최적치와는 거리 가 멀다. 대부분의 사람들은 막연히 젊은 세대, 기술발전, 복지정책에 의지하며 위로 를 삼는다. 추상적인 기대, 희망, 퍼주기식 복지로는 위기를 해결할 수 없다. 개인이나 정부나 위기의식을 가지고 위기를 극복하려는 적극적인 노력과 개입을 해야 한다. 너 지식 접근법은 이미 수많은 연구와 정책적 실행을 통해서 그 효율성과 효과성을 입증 해 왔다. 퇴직연금 자동가입이나 연금저축의 중요성을 알려 주는 간단한 이메일 메시 지를 회람시키는 너지식 접근법만으로도 연금가입율과 연금저축률 획기적으로 개선할 수 있다. 본 연구는 너지식 접근법이 연금가입율이나 연금저축률을 부지불식간에 늘 릴 수 있는 가능성을 포괄적 선행연구 검토와 비모수검증을 통해 보여 준다. 기존의 경제적 접근법과 병행되어 사용된다면 그 효과는 배가될 것이고 새로운 위기는 새로 운 기회가 될 수 있다. The rapid growth in aged population and life expectancy exacerbated by the substantial decline in birth rate have created a new type of crisis: retirement crisis. People and governments are not familiar with this new problem and more seriously, they are not well prepared for it. The retirement saving rate is far from an optimal level and the majority of people passively rely on hopeful growth in production population, development in technology, and aggressive spending in welfare policy. We need a more active and effective cure to circumvent the rising crisis. Nudging is a great candidate with excellent history of success for such task. The present paper aims at comprehensively reviewing prior studies on the impact of various nudges on the rates of retirement participation and contribution and providing an analytical summary of non-parametric tests in which nudging activities at the corporate and governmental levels can significantly alter the retirement savings behavior and eventually the quality of post-retirement life. Specifically, a variety of nudging skills such as automatic enrollment and informative email improve the employee participation and additional savings in retirement plans at the corporate and public levels. Nudging might be a key to turn the new crisis into a new opportunity.
