본 연구에서는 강우량이 여름에 집중되어있는 우리나라의 강우 특성을 잘 나타낼 수 있는 최적의 확률분포형을 선정하고 해석적 확률모델 (Analytical Probabilistic Model, APM)을 개발하여 유출량을 예측하고자 하였다. 국내 10개 지역인 부산, 춘천, 대구, 대전, 전주, 진주, 서울, 속초, 태백, 원주를 연구 지역으로 설정하였고, 30년 시 단위 강우자료를 지역별 interevent time definition(IETD)을 적용하여 강우 사상으로 그룹화하였다. APM 연구에 일반적으로 사용되는 일변수 지수 분포 이외의 이변수 지수, 감마, 이변수 로그정규 확률밀도함수 (Probability Density Function, PDF)를 강우사상의 특성인 강우량, 강우 지속시간, 무강우 시간의 히스토그램에 적용한 결과, 이 변수 로그정규분포가 우리나라의 강우 특성을 가장 잘 대표하였다. 로그정규분포를 이용하여 APM을 유도하고 유출량을 예측하였다. 예측한 유출량에 대한 빈도분석을 수행하여 Storm Water Management Model (SWMM)의 결과와 비교함으로써 유도한 APM의 적합성을 확인하였다. SWMM의 입력 매개변수 보정을 위해서는 서울 군자 지역에서 관측한 실제 강우량 및 유출량 자료를 사용하였다. 로그정규분포로 유도한 APM과 SWMM의 빈도분석 결과를 비교하였을 때 초과 확률과 재현주기 모두 매우 유사한 결과를 나타내었음을 확인하였다.

This study aims to provide a customized dynamic kiosk screen that considers user characteristics to cope with changes caused by increased use of kiosks. In order to optimize the screen composition according to the characteristics of the digital vulnerable group such as the visually impaired, the elderly, children, and wheelchair users, etc., users are classified into nine categories based on real-time analysis of user characteristics (wheelchair use, visual impairment, age, etc.). The kiosk screen is dynamically adjusted according to the characteristics of the user to provide efficient services. This study shows that the system communication and operation were performed in the embedded environment, and the used object detection, gait recognition, and speech recognition technologies showed accuracy of 74%, 98.9%, and 96%, respectively. The proposed technology was verified for its effectiveness by implementing a prototype, and through this, this study showed the possibility of reducing the digital gap and providing user-friendly "barrier-free kiosk" services.

This research, targeting the college students majoring in health administration science in Kwangju & Chonnam, is aimed at understanding their satisfaction with majors according to general, relationship, consciousness, and subject satisfaction, and looking into the correlation between the satisfaction and further career choices. This research set the 270 prospective graduates its study subjects based on convenience sampling. It was found that the number of students who want to choose their further major-related careers as medical records technician was greatest among the research subjects, of whom 62.4% were satisfied with their major subject while there existed a little difference in major satisfaction by further career. In addition, the students who want to choose the career of medical records filer showed higher satisfaction with their major subject than those who want to choose other-major-related careers. In general characteristics among the influential factors of major satisfaction in major-related career choices of a students of health administration science department, the 2nd year classes' major satisfaction was found to be 4.13 times as high as the 3rd year classes while the major satisfaction of the group choosing their major subject spontaneously was found to be 8.04 times as significantly high as the group choosing their major subject involuntarily. As a result of the analysis of the influence on major satisfaction among the sub-province of major satisfaction, it was found that the group having high consciousness satisfaction was 3.93 times as significantly high as the group having low consciousness satisfaction. A logistic analysis of the influence of major satisfaction on further career choices, the major satisfaction of those wishing to choose their major-related career as a medical records technician was 2.06 times as significantly high as those who didn't choose a medical records filer as their career choice while the major satisfaction of the group spontaneously choosing the career of a medical records technician was 4.51 times as significantly high as that of the group involuntarily choosing the career of a medical records technician. There should be a plan for enhancing major satisfaction by each major-related career in consideration of the characteristics of health administration science department having diverse career choices.

The purpose of this study was to investigate the PAI profile of the beauty major students. They were used through the PAI inspection result of 298 university students located in the chungcheong province in 2019. The results are summerized as follows; First, when comparing the average scale of college students majoring in beauty with those of college students majoring in general, college students majoring in beauty displayed a higher profile type in clinical scale than those of university students in general, with significant differences in SOM and ALC. Second, SOM, PAR, AGG, SUI that were significant when comparing beauty majors and general majors to navigate the PAI scale that significantly predicts beauty majors. As a result of conducting stepwise regression analysis on the four factors as a search factor, the scale of SOM is extracted, and it becomes a diversion that can predict college students in the beauty major. Therefore, beauty majors are more obsessed with physical problems than the ordinary students, and have an impulse-oriented behavior. These results will be used as materials for selecting, managing, educating or consulting a student majoring in beauty and will provide many implications for career choices after graduation.

The purpose of this study is to investigate the structural correlation between career decision making self-efficacy, major satisfaction and occupation value of beauty major students by questionnaire collection and statistical analysis. Major satisfaction was found to be statistically significant at the significance level of .05 with respect to coccupation value and career decision making self-efficacy at p<.001. Occupation value was found to be statistically significant at p<.001 for career decision and job decision of career decision making self-efficacy and significance level .05. Therefore, it has been confirmed that the major satisfaction and job value are the factors that play a significant role in the self-efficiency of career decisions, and it is believed that continuous research on various variables that affect the self-efficiency of career decisions of beauty major university students is necessary.
