Permanent rental housing, the construction of which was strongly financed by the central government, is regarded as a social housing for those who fall within the lowest income bracket. Differing from "public rental housing", offered to tenants for sale after a five year rental period, this type of housing is intended for rental use on a long-tenn basis. At present, about 190,000 permanent rental housing units exist in Korea. According to a statistics, 15.6% of its residents did not pay their management fee and rental payment in 4 or more months in 2005, which places stress on the housing management. Based on the "eviction condition" stipulated in the tenancy agreement for permanent rental housing, a householder owning assets or a vehicle which is not used as his means of living, who is overdue with his management fee and rental payment for a long time, may be evicted from the house. However, there are many conflicts and problems between administrators/housing managers and residents in the process of enforcing this regulation. The purpose of this study is to explore the key issues associated with the present situation and the reasons why so many management fee and rental payment for permanent rental housing are overdue. For the purpose of research, data were collected from 10,990 permanent rental housing residents nationwide via a questionnaire survey in February 2007. One third of the respondents had an experience of more than 2 months overdue since they have moved in current residence. For further analysis, the respondents were divided into three groups, based on their working ability. The major finding showed that the group of respondents who have working ability required a more practical plan, such as employment, to have a sustainable life, while the other group of no labor force indicated a need for more housing allowance from the government. To suggest more specific alternatives for the subject of housing payment overdue, further comparison study should be performed between the residents of permanent rental housing and other low income tenants in private housing sector.

IETF mip6 WG에서 MN의 위치를 나타내는 '바인딩정보'를 안전하게 CN에게 송신하여 위치정보를 수정하는 RR프로토콜이 2004년 6월에 RFC 3775로 표준화되었다. 표준화된 RR프로토콜은 시작주체 및 시점이 MN에 의해 이루어짐으로서 위치정보수정 지연에 따른 홈네트워크의 부담 및 통신지연 증가를 문제점으로 지적할 수 있다. 또한 보안측면에서 CN과 HA간에 위치하는 공격자에게 취약성을 내포하고 있다. 본 논문에서는 MN의 위치정보 수정권한을 HA로 위임시키는 새로운 위치정보수정 방안을 제안한다. 즉, MN의 위치정보를 HA에 등록시 MN의 개인키로 서명된 위치정보 인증서를 사용하여 등록하고 이 인증서를 HA가 CN에 MN의 위치정보 수정시 사용하는 방안이다. 이를 통해서 위치정보수정에 소요되는 시간을 단축하고 교환되는 메시지 수를 감소시켜 통신부담을 경감시키는 효과를 얻을 수 있다. 또한 CN과 HA간에 위치한 공격자에 대한 보안 취약성을 제거하였다.

이동 노드가 홈 망을 벗어나 이동하는 경우 현재 위치 정보를 홈 에이전트로 등록해야 한다, 그러나 이동 노드의 홈 에이전트가 홈 망의 VPN 게이트웨이에 의해 보호되고 외부로부터의 비 인가된 엑세스가 차단되는 경우 이동 노드는 등록 절차를 성공적으로 실행할 수 없는데 이는 이동 노드가 외부 망으로부터 얻은 임시 주소(CoA)와 홈 망의 보안 정책간의 보안 협약(SA)의 부재로 인해 바인딩 등록 메시지는 VPN(Virtual Private Network) 게이트웨이에 의해 차단되기 때문이다. 이 논문은 인터넷에 존재하는 Mobile IPv4 사용자가 VPN 게이트웨이에 의해 보호되는 인트라넷을 엑세스할 수 있도록 AAA 인프라 구조를 사용한 인증 및 키 교환 방법을 제시한다. 각 에이전트나 릴레이 엔티티를 위한 인증 및 터널 처리를 정의함으로써 이동 중인 노드가 안전한 방법으로 VPN 내부의 홈 에이전트로의 바인딩 등록 절차를 하였고, 이동 및 트래픽 특성에 따른 인증 비용 항목에 대해 일반적인 방식과 제안 방식을 비교하였는데 최대 40% 성능향상을 보였다.

Technological innovation depends on the quality of workers, whose ability is the key component to raise business competitiveness. Our study evaluates how satisfactory is the training of workers at small and medium sized firms, and suggest how to improve upon it. We show the theoretical framework for the relation between customer satisfaction and their behavioral intent on the one side, and factors of training service quality. Our result show: (1) Factors affecting customer satisfaction are, in descending order of importance, expertise, policy, follow-up service, attitude and behavior, and convenience. (2) Contrary to established views on the service quality, satisfaction for training would not be the prerequisite variable for intent to act, in case of training service quality. (3) Satisfaction level for training depends on the type of organization in charge of training (government, university, or private sector.) It also varied among different types of business (L-type, A-type, and J-type.) Small and medium sized firms find it difficult to commit to training education due to lack of money and manpower. The recent expansion of free training service would address part of this problem. On the other hand, the outfit in charge of training could boost service quality by customizing their training program to the type of business they cater to.

The purpose of this study was to propose HACCP system implementation properly and to secure the food safety of school foodservices in Pohang city since the proper facilities and equipment should be key factors in food safety and production. So this study was designed to evaluate existing equipment in food production area, receiving and dining area, and employee facilities. Questionnaire was mailed to 107 school foodservice dietitians in Pohang area and 97 were responded (90.7% response rate). Approximately sixty percent of foodservices were not available separate receiving or polluted area, fifty one percent were installed screen door for insecticidal and temperature and humidity control, and these environmental conditions were hard to keep kitchen dry and sanitary condition. Usually public schools were better equipped than private schools. Forty three percent of school foodservice had initial use of non-foodservice, opened before 1994, and thirty three percent of elementary school foodservice. Among employee facilities, hand washing sanitation stand was prepared seventy nine percent (78.9%) of school foodservices. Dietitians chose outworn equipment and facilities (30.9%), difficulties of maintaining standard temperature and humidity for foodservice (20.6%), lacking separate receiving or polluted area (13.4%), indirect contamination of water hoss (10.3%), and lacking employee facilities (10.3%) as critical points to correct in school foodservice. Therefore governmental regulating agencies must review and approval of plans prior to new construction or extensive remodeling of school foodservice facilities. In addition to these requirement, plan must be set-up step by step to implement HACCP system properly.

본 연구는 유자녀가구를 가구주의 성별에 따라 남성한부모가구, 여성한부모가구, 양부모가구로 분류한 다음 가구유형별 경제적 빈곤실태를 비교하여 분석하였다. 그 결과, 한부모가구라 할지라도 가구주 성에 따라 이질적인 사회인구학적 특성이 발견되었다. 또한 여성한부모가구주들은 대졸 이상의 학력을 가진 경우에도 상대적 빈곤층에 속할 확률이 높았다. 이는 단순히 인적자본의 확충만으로는 이들 가구를 상대적 빈곤에서 벗어나게 하는 데 많은 제약이 있음을 의미한다. 다음으론 경제적으로 취약한 한부모가구들에서 이전소득보다는 가구주 근로소득의 절대적 비중이 크게 나타났다. 한부모가구의 빈곤탈출을 위한 제언은 다음과 같다. 첫째, 최저생계비 기준의 단순한 상향조정보다는 어린 자녀를 가진 한부모가족을 위한 직접적인 양육 및 주거비절감 대책이 요구된다. 둘째, 남성한부모가구의 경우에도 공적이전소득의 빈곤감소효과가 매우 적기 때문에 이에 대한 제도적 보완이 시급하다. 최저생계비 결정 및 집행과정에 있어서도 현재는 가구원 총수만이 고려되고 있으나, 사적이전소득의 격차와 기타 사회인구학적 특성의 차이를 고려하여 가구주의 성별, 자녀수, 자녀의 연령 등에 따라 차등화된 세부 기준에 따라 시행되는 편이 보다 합리적이다. 셋째, 저소득층 한부모가구주들을 대상으로 보다 나은 근로조건과 경제적 인센티브를 주는 근로연계형 복지제도와 대상자의 특성별 맞춤형 직업훈련 프로그램이 시행되어야 한다.

The main objectives of this research are to compile all the researches published in the registered academic journals to study the trends of researches and analyze the relationships between research contents and the social factors so that the accomplishments of community related researches and future tasks can be identified. For this purpose, 97 papers published between 1973 and July 2011 were chronologically organized and analyzed in terms of research methods, main contents, and their relationship with social factors. The key findings are as follows; 1) Researches on multi-family-housing community started in 1973 mainly focusing on the social factors of neighbors in a complex; since 2000, however, the researches on physical factors were increased the most followed by psychological and social factors accordingly. 2) The research findings were not fully developed to give a guidance for appropriate space programs or an analysis of residents' preference on facilities. The cause of this shortfall is due to the fact that there was a lack of studies on residents' usage of community facilities based on quantified database. 3) More comprehensive researches should be conducted in the future for vitalizations of community through facility supply system and design guidelines, development and operation of community programs and measures to enhance community awareness targeted on public housing and more diverse types of housing being apart from typical multi-family-houisng provide by private sector.

Broadcasting telecommunication convergence service means a service where broadcasting and telecommunication converge. Recently with the advancement of technology, broadcasting telecommunication convergence service has been evolving to provide multimedia contents through various devices including wired and wireless network environment. Up to now, IPTV and smartphone-based convergence services have been dominant, but more developed and evolved technology and media will appear in the future. In order to derive the next generation broadcasting telecommunication convergence service supporting model, this study derives an evaluation model of broadcasting telecommunication convergence service and presents a case of evaluation of 30 demonstration projects supported by the Korean government from 2010 to 2014. In this study, we derive an evaluation model and evaluate the demonstration projects by reflecting the position of the main stake holders of service such as users, experts, and related organizational institutions, away from the existing simple service evaluation method. Expert questionnaire used AHP (Analytic Hierarchy Process) method, and the evaluation results were divided into upper and lower groups to provide key implications by a gap analysis. From this analysis this study suggests guidelines for next generation broadcasting telecommunication service support projects. The next generation broadcasting convergence service business should be based on open platform type in terms of service type. In terms of service media, it should be centered on open devices such as smart phones and smart TVs. In terms of types of business responsibilities, it should be led by public organizations and it is necessary to increase the fund matching ratio by at least 62% when the private sector participates.
