오늘날의 미디어는 디지털 방송이 본격적으로 발전하고 또 우리의 삶에 녹아들고 있다. 특히 인터랙티브 미디어는 컴퓨터를 기반으로, 기존처럼 시간에 맞춰 주어진 미디어를 눈으로만 시청하기보다, 미디어를 직접 따라 하거나 미디어의 선택지를 고르는 등 사용자와 미디어의 상호 작용을 통해 차별화된 콘텐츠를 체험할 수 있는 형태로 확장된 미디어이다. 최근에는 이를 활용해, 특정 센서 및 디바이스가 부착된 옥외 광고나 전시관 등에 사용자의 자연스러운 참여를 유도할 수 있는 콘텐츠 개발이 활발히 진행되고 있다. 그리고 저가의 모션 인식 디바이스가 개발되어, 신체에 접촉하지 않으면서 사용자의 모션 정보를 인식하여 다양한 인터랙션을 적용한 미디어를 체험할 수 있게 되었다. 본 논문은 특정 프로그램 설치가 없이 웹서비스 환경에서 사용자의 동작을 인식하고 영상을 제어할 수 있는 인터랙티브 미디어 플레이어를 개발하였다. 그리고 키오스크 형태에서 탑재된 립모션(Leap Motion) 장비에 맞는 다양한 사용자 동작 인식 범위를 설정하고 사용자 동작 인식 알고리즘을 개발하였다. 이러한 연구 결과는 인터랙티브 관광·교육·영화 콘텐츠등 다양한 인터랙티브 미디어를 공공의 장소에 설치 가능한 키오스크에 탑재하여 체험할 수 있다.

In recent years, deep learning techniques have achieved tremendous successes in natural language processing, speech recognition and image processing. Collaborative filtering(CF) recommendation is one of widely used methods and has significant effects in implementing the new recommendation function, but it also has limitations in dealing with the problem of poor scalability, cold start and data sparsity, etc. Combining the traditional recommendation algorithm with the deep learning model has brought great opportunity for the construction of a new recommender system. In this paper, we propose a novel collaborative recommendation model based on auxiliary stacked denoising autoencoder(ASDAE), the model learns effective the preferences of users from auxiliary information. Firstly, we integrate auxiliary information with rating information. Then, we design a stacked denoising autoencoder based collaborative recommendation model to learn the preferences of users from auxiliary information and rating information. Finally, we conduct comprehensive experiments on three real datasets to compare our proposed model with state-of-the-art methods. Experimental results demonstrate that our proposed model is superior to other recommendation methods.

The relatively recent emphasis on a total allowable catch(TAC) system is placing new demands on fisheries management. Korean fisheries law has provided recently for implementation of the TAC based on fishery management system, in order to conserve and manage fisheries resources rationally in its exclusive economic zone(EEZ). In 1998, the TAC system was first applied to Korean fisheries. This TAC system is currently undergoing a second trial period, having been put under the system for 20012002 and continuous trial basis until the complete settlement of EEZ system agreement among three countries, Korea, China and Japan. The TAC system implementation needs are sophisticated information collection, analysis and modeling that will continue to increase and require the high management resources. In addition, data on social and economic impacts on TAC system is sometimes inadequate. The implementation of the TAC system provides a unique opportunity to examine the limits of management information and resources, and to solve the problems in Korean fisheries management system, These limits and problems are complicated by an inadequate biologically and economically information and insufficient management resources. Government and fisheries cooperatives must be cooperated in the management process in order to minimize its conflicts and maximize commitment to sustain fishery development. Recognition of the ineffectiveness and its potential consequences leads to the adoption of the cooperative-based co-management approach in implementation of TAC system. In 1998, the TAC system was first applied to Korean fisheries, where traditional fishery management has consisted mainly of technical measures and input controls. The QMS of TAC system has been implemented in the form of cooperative-based co-management framework. This QMS framework was chosen to overcome many difficulties and limits that a competitive TAC system would impose on Korean traditional fisheries management. The implementation of the QMS of TAC system provides a unique opportunity to examine the limits of management information and resources, and to solve the problems in Korean fisheries management system.

This study attempts to analyze the factors affecting the intention of transferring to another hospitals among radiology technologists. 344 cases were reviewed in 5 university hospitals and 1 general hospital. Self-administered questionaire were given to study the socioeconomic characteristics, working conditions, job satisfaction level, and the reasons for transfer among the technologists. The major findings were as follows : 1. Job position and hospital characteristics had a statistically significant relationship with the intention of transferring to another hospital. 2. Those who were not satisfied with their salaries and promotional opportunity showed a higher tendency towards to transfer. 3. Those who were less satisfied with the opportunity for developing the personal ability and had the negative attitude on their job showed a higher tendency to transfer. 4. Those who did not sustain good relationship with their superiors and co-workers scored high on the tendency to transfer. 5. In the result of mutiple regression, recognition of radiation hazard, job satisfaction, satisfaction with salary levels, job attitude were significantly related to transfer. The above indicate that besides economic incentives, job satisfaction and organizational culture to promote their ability and form a good relationship with organization members were very important to decrease the intention of transfer. Since these results represent only 6 hospitals from a limited area, more hospitals nationwide, especially small and medium-sized institutions where there is a high turnover rate of employment, need to be examined in order to investigate the various factors that affect the intention of transferring.

The purpose of this study is to examine public health nurses for their morale, test the effect of each factor on the morale, determine the variables affecting the morale, and thereby, provide for some basic data useful to the development of personnel affair administration for nurses. The survey on the nurses for public health centers was conducted for 10 days from April 23 to May 2, 2001; 96 nurses from Pusan, 101 from Kyonggi-do and 108 from Kangwon-do. The results of the study are as follows; 1. For the demographic variables, those aged between 31 and 39 accounted for the majority $(50.2\%)$ of the sample. $90.8\%$ was married, and $67.9\%$ of the sample graduated from junior colleges. $29.6\%$ of them had worked for 10-14 years and $62.5\%$ was of the seventh rank. $62.3\%$ of the nurses was recruited, and $59.4\%$ had chosen the public job for its guaranteed status. Half the nurses were working for the county population of which was more than 260 thousands, and $53\%$ of the nurses was serving the public health centers with 11-15 members. $47.3\%$ of them perceived that their living standard is middle or lower. 2. The degree of the moral was found as mean score. 2.65, which is interpreted as low. It has 11 factors. The rank of mean score of the factors is job satisfaction (3.36), sense of belonging (3.36), sense of recognition (3.30), stress due to supervision (3.13), degree of participation (3.05) and self-achievement (3.04), while those scoring lower points were assurance of status (2.58), pay level (2.53), working conditions (2.35) and promotion opportunity (2.31). 3. The degree of moral depending on the demographic variables was significantly affected by such variables as age. academic background, career, rank, employment method, motive for the job, size of the population served and living standards. 4. The result of the Stepwise multiple regression analysis for the morale factors, it was found that self-achievement accounted for $61\%$ of the total variance of the degree of morale, followed by stable status $(18\%)$, working conditions $(8\%)$, job requirements $(4\%)$ and promotion opportunities $(2\%)$; these five factors explained about $94.6\%$ of total variance of the degree of nurses' morale. On the other hand. age $(8\%)$ and academic background $(2\%)$ accounted for $10\%$ of the total variance of the degree of morale. 5. The factors affecting nurses' job life was economic need $(26.7\%)$, personnel management $(17.5\%)$, sense of recognition $(13.2\%)$, human relationship $(11.0\%)$, stable status and personal development in rank. On the other hand, the factors influencing on their possible resignation were children's bringing-up $(27.8\%)$, poor personnel management and promotion $(13.3\%)$, workload $(11.1\%)$ and little personal development $(8.9\%)$, Since such morale factors as promotion opportunity, working condition. pay level and stable status scored lower, it is required to reconsider those factors to improve nurses' morale.

Objectives : The recognition rate for issues and improving resolution for the recuperation income expense claim policy was examined. Methods : 1,135 copies of survey have been sent to the group of people who have claimed the dental recuperation income expense to dental recuperation institutions in Daejeon, Chungcheong Do that are registered to the health insurance evaluation and estimation office as of the May 2010 and 207 surveys that were regarded to be sincere for answering were analyzed. Results : Majority of respondence were belonged to the dentist institutions with more than 5 years of claim experiences as well as 10~50% of claim rate. The recognition of medical fee evaluation guideline was normal level, and negative recognition was higher to the health center with daily charge policy compare to the dental hospital and university affiliated dental center with treatment charge policy, Highest opinion for inappropriateness of dentist with significance was found (p<0.05). The openness of evaluation cases are regarded to be discharged through the transparent evaluation and most of the opinions for insurance claim evaluation adjustment are within the both 'Do not understand the evaluation guideline and program error of disease category, code and program' with significance(p<0.05). The reaction after the evaluation adjustment was high in reflection on the claim process after examining the reason for the evaluation adjustment through the evaluation and estimation office and university affiliated dental institution and dental center was regarded to be most active and deputy reclaimment was seemed to be most actively discharge the objection registration task (p<0.05). The claim error improving resolution recognition was highly prioritized to the accurate charting for the disease title and treatment description, improving the setting of claim program, and most highly recognized by the university affiliated dental hospital/dental center and comparably low by health center(p<0.05). and although the most of the responds of treatment description and browsing the medical fee was positive, 50% of dentists disagreed the idea so that this was creating a significant discrepancy with other groups(p<0.05). Conclusions : From this research, the recognition of medical fee evaluation guideline for dental (university) hospital and dentists were negative and high adjustment experience was examined as lacking of evaluation guideline understanding and error of disease name, code and programs and deputy reclaimment, university affiliated dental hospital/dental center were most actively handle the objection registration tasks and dentists have objection on the treatment description and browsing the treatment fee so that if these indexes can be referred to implement into the recuperation income claim process, this can be regarded to be a opportunity to create mutual credibility between recuperation institution, treatment pensioner and the evaluation institutions.

본 연구는 국내 창업 환경 개선 및 바람직한 창업 인식 조성방안을 모색하기 위해 2016 글로벌 기업가정신 트렌드 보고서(GETR)의 데이터(20개국 40,354명)를 활용하여 주요 국가의 기업가정신 교육 현황 및 국가별(유형별) 창업 실태, 그리고 기업가정신과 창업 의지 및 기회형 창업의 관계를 분석하였다. 연구 결과에 따르면 먼저 한국은 기업가정신교육의 확대가 시급한 것으로 분석되었다. 한국의 '초중고 기업가정신교육 경험'은 20개국 중 최하위수준(19위)이었으며, '대학' 및 '평생교육'은 중위권(15위)인 것으로 나타났다. 또한 전세계적으로 기업가정신교육은 연령대를 불문하고 활성화되고 있음에도 불구하고, 국내 중고령자에 대한 기업가정신교육은 상대적으로 미약한 수준이었다. 이는 향후 평생교육 차원의 교육 확대가 요구되며, 재직자 및 은퇴예정자 대상 기업가정신 교육 개발 및 확대가 필요함을 시사한다. 둘째로, 한국인 개인의 창업의지는 3.8점으로 중하위권(15위)이었고, 기회형 창업수준은 최하위(20위)였다. 중국(4.55) 및 미국(4.01)과 비교할 때 한국인의 개인 창업의지는 상대적으로 낮은 것을 확인할 수 있었고, 기회형 창업 수준 또한 한국은 3.43점으로 중국(4.35), 일본(4.04), 미국(4.59)에 비해 매우 낮은 것으로 확인되었다. 일반적으로 요소주도형${\rightarrow}$효율주도형${\rightarrow}$혁신주도형으로 전환될수록 기회형 창업의 비중은 높아지는데, 한국의 경우 비자발적 창업 및 소상공 중심의 창업 비중이 높아 기회형 창업 수준이 낮은 것으로 해석할 수 있다. 마지막으로, 요소주도형, 효율주도형, 혁신주도형 모든 유형에서 기업가정신교육 참여에 따른 창업의지는 매우 높은 것으로 나타났다. 특히, 혁신주도형일수록 모든 기업가정신 교육(초중고, 대학, 평생교육) 참여여부에 따라 신규창업의지는 크게 증가하고 있음을 확인하였다. 혁신주도형인 한국의 경우 기업가정신교육의 양적 확대를 기반으로 질적 제고를 이룬다면, 지금의 중하위권(15위)에 머문 국민의 창업의지를 상승시킬 주요한 원동력이 될 것으로 예상된다.
