Along with IT development, customers are getting more easily to express their opinions using various IT channels. In this situation, complaint management is a pressing issue for companies to acquire and maintain loyal customers with low cost. Most of previous studies have investigated customer complaint information by quantitative variables such as demographic information, transaction information, or complaint frequency, but studies focusing on qualitative aspects of complaint information are limited. Therefore, this paper considers the possibility for customers to leave even when they complain occasionally or briefly. This paper analyzes the quantitive aspects as well as the qualitative aspects using sentiment analysis with Exit-voice theory. The dataset contains 268,364 inquiries of 46,235 customers obtained from a contact center of a private security company in Korea. This paper carries out logistic regression and the results imply that the customers's explicit response and their implicit sentiment have different effect on customers leave. This study is expected to provide useful suggestions for the effective complaint management.

최근 전력공급의 질적인 향상 요청으로 전력 설비의 안정성에 대한 요구가 날로 증대되고 있으며, 특히 변압기의 신뢰성 향상과 사고의 미연방지를 위한 예방 또는 예측진단기술의 중요성이 크게 인식 되고 있는 실정이다. 변압기는 운전중에 각부가 열화등으로 전기, 기계적인 성는이 저하되어 이상이 발생되는 겅우가 있는데, 그 이상을 사전에 검지하여 적절한 조치를 취하지 않으면 중대한 사고를 일으키는 수가 있다. 이러한 사고를 미연에 방지하기 위해서는 이상의 징후를 초기단계에 검출하여 이상의 내용을 정확히 파악하고 대책을 수립할 필요가 있다. 이러한 이상유무를 진단하는 많은 방법들이 실용화 되어 있는데, 변압기와 같은 유입기기의 이상진단 방법중 가장 효과적인 보수관리법으로서 유중가스 분석에 의한 방법을 들 수 있으며, 국내외의 여러 전력회상서 채용하여 사고예방에 크게 기여하고 있는 것으로 조사되어 있다. 따라서 본 란에서는 유중 용존가스 분석에 의한 변압기의 일반적인 내부이상 수소가스에 의한 진단법에 대해서 그 진단기술의 이론적 근거와 진단장치의 구성 등을 중심으로 기술하고자 한다.

본 연구는 연기전공 대학생들의 움직임훈련을 통해 자신의 신체를 인식하고 표현변화 과정를 알아보는 것이다. 참여자는 연기전공하는 남녀 대학생 25명으로 연구자가 제안한 주 1회 8주 프로그램을 시행하였으며, 자료분석은 심층면담과 설문지를 토대로 귀납적 내용분석을 실시하였다. 분석결과 참여자들은 자신의 신체를 인지하고 정렬하게 되었으며, 표현력의 인식과 범위에 제한을 두지 않게 되었음을 인지하는 것으로 나타났다. 따라서 본 신체훈련 프로그램은 참여자들의 움직임 인식변화에 영향을 미치는 것으로 나타났으며 본 연구결과는 연기전공 대학생들의 움직임 인식변화와 신체표현 확장에 연계하여 논의하였다.

This study is focusing on teenagers who are needed a correction program called "Gillwe School". This program has a companion who is called a guide and the guide leads them correction program while walking with teenagers. This report has represented 131 semantic units, 7 sub-constituencies and 4components through analysis of 46 cases of the companion participants stories since 2014 and clearly, defined as the final four regions ("Understanding of protection youth", "Positive change of companion's gaze", "Doubts the walking program", "Program's effectiveness and Companion's importance,".) Through a series of studies, I look forward to finding ways to develop programs for the protection of juvenile correctional professionals, such as trarining professional counselors for protection youth, duration and number of correction programs, and expanding the number of participants.

수작업에 의한 보전관리방식은 고장신고에 의하여 수행되는 사후 관리방식으로서 가입자 회선의 급속한 증가에 따라 필요한 보전 인력 확충이 어렵고 보전 작업량의 예측이 힘들어 정확한 보전계획 수립이 불가능하다. 또한 고도로 숙련된 운용요원을 요구하는 수동식 시험대는 교환기종마다 상이하여 획일적인 보전관리가 이루어지지 않는다. 이러한 문제점을 해결하기 위하여 가입자 시설 집중보전 시스템 (SLMOS)을 개발하였다. SLMOS구성은 일정 지역별로 지역보전 센터를설치, 여러 전화국을 수용하는 형태로서, 가입자 고장신고 접수 및 수리시험 요원을 집중시켜 인력절감을 꾀하며 각종 보전업무의 전산화로 가입자 서어비스의 질적 향상 및 능률적인 보전관리를 도모한다. 가입자 고장신고는 집중화된 접수요원이 담당하며 전화번호만 key-in시키면 고장원인 및 수리약속 시간이 CRT화면에 나타나므로 가입자에게 정화한 정보를 제공한다. 지역보전 센터의 프린터에는 접수요원이 받은 고장신고 내용 및 심야에 실시된 예방시험의 결과가 출력되므로 통제석에서 이를 분석, 해당 수리 시험석으로 분배한다. 모든 요원의 작업내용은 고장기연 data base에 저장되므로 지역보전 센터 의 관리자는 원하는 각종 통계, 분석 자료를 출력시킬 수가 있어 보전업무의 효율적 운영을 할 수 있게된다. SLMOS의 software개발에 UNIX 0S를 사용함으로써 machine independence와 시스템의 융통성 및 Portability를 추구하고있으며 신고접수, 수리에 mask기법및 한글사용으로 용이하게 시스템을 사용할 수 있도록 하였다. 자동 선로시험 장치에 $\mu$-processor를 내장시켜 예방시험 기능의 추가와 자동 고장판정으로 운용요원의 기량에 의존하는 방식의 탈피를 시도하였다. 본 연구개발은 81년에 착수하여 84년에 완료할 예정이며 82년말 중앙전화국 시험실에서 연구소 computer와 on-line 방식으로 시험 운용을실시하였다. 83연도에 시스템기능을 보완 및 추가 개발하고 84년도에 현장 및 실용화 시험을거쳐 한국전기통신공사에 공급할 계획이다.

The purpose of this research was to analyze the contents of Housing Studies in Home Economics Education of Secondary School published in master's or doctorial theses and journals since 1985. The 24 research papers were analyzed by the type and time of publication, research subjects, data collecting methods, respondents & sample size, and statistical methods. The data were presented by tables with frequencies. The results showed that the most Housing educational research has been done as a type of theses and the number of published papers on Housing has been increased in somewhat. Over time there were two main theme of Housing educational research: general perception of housing and teaching - learning plans. Research methods, respondents and sample size, and statistical methods were obviously differed by the two research theme of Housing educational studies. This research suggested to broaden the research subjects as well as research methods beside to increase the number of studies on Housing area in Home Economics Education.

Purpose: The end of one's life can be one of the most important times in human life. However, physicians, nurses and volunteer workers are not sufficiently trained to understand the end-life care with competence and confidence. The purpose of this study was to compare various education programs currently carried out for volunteer workers. Methods: Nine curricula of hospice and palliative cares for volunteer workers at hospital and palliative care settings. Results: The mean time duration of theory education at nine institutes was 21.56 hours (range; 14-30). The common curricula of hospice and palliative cares for volunteer workers included 'Understanding of hospice and palliative care', 'Understanding of life and death', and 'Understanding of psychologic problem of end-of-life'. The education method comprised lectures, off-line 8 institutes and on-line 1 instiutute. Conclusion: It is necessary to develop the standard curriculum as well as regularly updated education program for volunteer workers.

The purpose of this study was to explore perception about shared decision making of family caregivers of patients with early dementia (PWED). This study was conducted with a sample of 12 family caregivers (mean age = $71.4{\pm}10.4$) of PWED from three dementia safety centers in Seoul. In-depth interviews were done for each participant about shared decision making and data were analyzed using qualitative content analysis. Six categories and 17 sub-categories identified for participants' perception about shared decision making: means to facilitate communication with patients with dementia, means to secure autonomy of patients, opportunity to facilitate treatment, cause of increasing family caregivers' burden, cause of worsening relationship with patients, and option for choices depending on priority change. The findings of this study can provide a knowledge basis for health care professionals and policy makers to understand how family caregivers of PWED think about shared decision making. It would be of great value to develop educational programs and practical guidelines about shared decision making for PWED and their family, which may contribute to respecting PWED's self-determination right as well as reducing burden of their family.

The purpose of this study is to examine the perception of PBL hybrid curriculum of nursing students, using qualitative research conducted through focus group interviews. The data were collected from interviews with 25 nursing students of 4th grade after dividing into 4 groups. The analysis resulted in 6 major categories such as 1) inefficiency of PBL hybrid curriculum, 2) anxiety about learning, 3) dissatisfaction with PBL operation, 4) difficulty in group activity, 5) acceptance of PBL and 6) change and satisfaction. Based on the result, it is suggested that measures should be taken to minimize loss of learning contents in PBL, proportion of course evaluation should be increased to follow original intention of PBL evaluation, and detailed tutor education program should be developed and operated by PBL specialist and professional department.
