본 연구는 한국장학재단 일반상환 학자금 대출 연체자를 대상으로 연체 미회수 그룹으로 분류될 수 있는 위험요인들을 파악하고, 학자금 대출 연체 회수 예측모형을 개발하였다. 또한 개발된 예측모형을 활용하여 그에 따른 신용위험 평점표를 작성하였다. 예측모형 개발은 연체기간에 따라 총 3가지 모형 (Model 1: 연체 1개월 모형, Model 2: 연체 2개월 모형, Model 3: 연체 3개월 이상 모형)으로 로지스틱 회귀분석 분석을 적용하였다. 연체기간 구분은 금융권에서 일반적으로 사용하고 있는 연체회수모형의 단위를 준용하여 1개월 단위를 기준으로 연체 1개월, 연체 2개월, 연체 3개월 이상으로 구분하였다. 연체 1개월 모형 (Model 1)에서는 연체계좌수, 이체일자, 연체잔액, 소득분위가 영향력이 큰 것으로 나타났으며, 연체 2개월 모형 (Model 2)에서는 연체 일수, 연체잔액, 이체일자, 연체금액이 중요한 것으로 나타났다. 마지막으로 연체 3개월 이상 모형 (Model 3)에서는 최근 3개월 이내 연체 횟수, 이체일자, 연체계좌수, 연체액의 영향력이 큰 것으로 나타났다. 본 연구에서 개발된 연체회수 모형이나 평점표를 바탕으로 연체 채권관리를 함에 있어 좀더 세분화된 관리서비스를 제공하고, 상담센터의 상담원이 연체자의 평점에 따라 상담전략을 세울 수 있는 기초자료가 될 수 있을 것으로 사료된다.

This work was conducted to find the operating characteristics of an efficient wet grinding system designed to obtain fine rice husk ash powder. Once the rice husk was combusted and the thermal energy was recovered from the furnace, the ash was fed and pulverized in the grinding system resulting a fine powder to be used as a supplementary adding material to the portland cement. Grinding time (15, 30, 45 min), impeller speed (250, 500, 750 rpm), and mixed ratio (6.7, 8.4, 11.l, 20.9) were three operating factors examined for the performance of a wet-type stirred ball mill grinding system. For the operating conditions employed, mean diameter of fine ash powder, specific energy input, and grinding energy efficiency were in the range of $2.83{\sim}9.58{\mu}m,\;0.5{\sim}6.73kWh/kg,\;and\;0.51{\sim}3.27m^2/Wh$, respectively. With the wet-type stirred ball mill grinding system used in this study, the grinding energy efficiency decreased with the increase in total grinding time, impeller speed, and mixed ratio. The difference in specific surface area of powder linearly increased with logarithm in total number of impeller revolution and the grinding energy efficiency linearly decreased. Grinding time of 45 min, impeller speed of 500 rpm, and mixed ratio of 6.7 were chosen as the best operating condition. At this condition, mean particle diameter of the fine ash, grinding energy efficiency, grinding throughput, and specific energy input were $2.84{\mu}m,\;2.28m^2/Wh,\;0.17kg/h$, and 2.03kWh/kg, respectively. Wet fine grinding which generates no fly dust causing pollution and makes continuous operation easy, is appeared to be a promising solution to the automatization of rice husk ash grinding process.

S 대학교 교양필수 과목인 영어회화는 영어교육을 강화하기 위해 블렌디드 학습으로 설계되었다. 이 블렌디드 학습이 학습자의 학업성취도에 어떤 영향을 미치는지 알아보기 위해 학업성취도의 변인에 대한 연구가 진행되었다. 연구결과로 성별, 전공, 군복무, 해외거주 경험, 면대면 출석, 퀴즈, 온라인 출석이 학업성취도에 영향을 미치고 온라인 학습방식(학습장소, 학습시간, 학습빈도)은 학업성취도와 상관이 없는 것으로 나타났다. 온라인 학습만족도는 강사 만족도, 학습내용 만족도, 시스템 만족도로 나누어 조사했는데, 그 결과 단지 시스템 만족도만 학업성취도에 영향을 미친 것으로 나타났다.

본 연구는 간호학과 학생들의 전공만족도와 교수-학생 상호작용이 대학생활적응에 미치는 영향을 규명하기 위한 서술적 조사연구이다. 본 연구의 자료 수집 기간은 2017년 7월 22일부터 8월 15일까지 실시하였으며, 본 연구를 위한 자료수집은 B광역시, U광역시, G시 소재 8개 대학의 간호학과 1, 2학년 학생 중 연구목적을 이해하고 자발적으로 연구 참여에 동의한 학생 중 부적절한 응답을 제외한 205명의 설문지를 분석하였다. 연구결과로 대상자의 일반적 특성에 따른 대학생활적응 정도는 학년, 건강상태, 대인관계. 희망진로, 학교성적, 가정생활정도에 따라 유의한 차이가 있었고, 전공만족도가 높고, 교수-학생 상호작용이 높을수록 대학생활적응이 높음을 알 수 있었다. 회귀분석 결과 전공만족도가 대학생활적응에 가장 높은 영향을 미치는 것으로 나타났다. 따라서 저학년들이 간호대학생으로의 전공에 대한 만족을 향상시킬 수 있는 교과내외의 프로그램을 지속적으로 적용하고, 입학시부터 지도교수나 교과담당교수진과의 다양한 의사소통이나 상담의 기회를 제공하도록 하여야 할 것이다.

Medical students' career choices hold significant importance at both individual and national levels. Therefore, Chungnam National University College of Medicine aimed to systematize its revised career fair in 2022, basing its efforts on a career planning process model. Chungnam National University College of Medicine sought to formalize the design process by utilizing the ADDIE model (analysis design, development, implementation, evaluation model) in developing programs for the career fair program. Throughout the entire process, the student support center and student council actively collaborated, striving to incorporate students' requests and opinions. They designed and developed a program for all stages of the career planning process. However, a new stage ("review & ref lection") was added to the existing 4-phase model, creating a transformed framework where this stage interacts with the original 4 phases. Each stage involved portfolios, career aptitude tests, career-related lectures, posters with introductory information about majors, and booths for each major. The revised career fair attracted double the expected participants (N=589). The program evaluation survey showed overall positive responses (N=135). Additionally, some factors in the Specialty Indecision Scale showed significant differences between before and after the career fair. The success of the newly developed career fair at Chungnam National University College of Medicine can be attributed to its systematic framework and the active involvement of students throughout the process. However, for aspects with long-term implications, such as "understand yourself " and "choose your specialty," there may be a need for supplementary programs.

In recent years, the relationship of language maintenance to culture and identity has received increased attention in the language acquisition and education fields. Korean immigrants in the U.S. form one of the biggest Asian groups and their language and cultural maintenance has been a major issue for both parents and ESL teachers. The present research is designed to investigate the cultural and social identities as well as the psychological investment factors that contribute to heritage language maintenance. Three Korean immigrant families in a small Midwest university town in the U.S. were surveyed and later interviewed. Issues and strategies concerning their children's Korean education in the U.S., coupled with the competing goal for the children to learn English were documented through parent interviews and interviews with school-aged focal children. Strategies and stances that facilitate or hinder both heritage and target language maintenance goals are presented along with participants' major reasons for heritage language maintenance in their homes and via Saturday schools. This work will assist ESL teachers and sociolinguists in situating both Korean student and parent goals in the context of shifting cultural and linguistic identities in countries where they have immigrated.

This research is designed for a consumer, not a supplier when it was designed. And the purpose is to present the reference data which is in order to improve the curriculum by analyzing the present subject of the curriculum. The research collected the curriculum for Dental Technology from a total of 20 schools --3-year colleges and 4-year colleges-- all in Korea. And we analyzed the average credits of subjects from students. As a result of this analysis, we get the conclusion below: 1. In a distribution which students answered about each subjects; Dental esthetic, Dental morphology I II, Dental morphology practice I II, and Seminar don't have many credits and mostly have a converged tendency in high points, according to the arithmetic mean of the major basis subjects. 2. In an analysis of the correlation which is based on the distinction of sex; Dental ceramics practice III, Medical terminology, Seminar, and The major basis subjects have a meaningful difference. (${\rho}$ < 0.05) 3. In an analysis of the correlation which is based on an age; The major basis subjects, and the application subjects have meaningful difference. (${\rho}$ < 0.05) 4. In a correlation coefficient between subjects; The correlation coefficient of the major application subjects is higher than the major basis subjects. According to the student ? t, we found that the level of significance is ${\rho}$ < 0.001, which is meaningful. We feel that Department of Dental Technology also highly need to design, and conduct focusing on a consumer who is working at the society, not a supplier. And we need to increase or decrease credits which have a meaningful difference.
