Currently, there are many subscriber access networks: PSTN, ADSL, Cellular Network, IMT200 and so on. To these service providers that provide above network service, it is important that they authenticate and authorize legal subscribers and account for their usage. At present, There exist the several protocols that Support AAA(Authentication, Authorization and Accounting) service : RADIUS, Diameter, TACACS+. Nowadays, RADIUS has used for AAA service widely. It has been extended to support other access network environment. So, we extend RADIUS to support environment of Mobile IPv6. Mobile IPv6 uses IPsec as a security mechanism, basically. But, IPsec is a heavy security technology for small, portable, mobile device. Especially, it is serious at IKE, the subset of IPsec. IKE is a key distribution protocol that distributes the key to the endpoints of IPsec. In t:lis paper, we extend RADIUS to support environment of Mobile IPv6 and simplify the IKE phase of IPsec by AAA system distributing the keys by using its security communication channel. Namely, we propose the key distribution method for IPsec SA establishment between mobile node and home agent. The suggested method was anticipated to be effective at low-power, low computing deyice. Finally, end users feel the faster authentication.

Purpose - A traditional retail market is a place that offers economic opportunity to employees and employers alike it also is a place where the community can meet. The Korean government has invested three trillion won to improve physical and non-physical aspects in traditional retail markets since 2004. However, little research on this has been conducted. We explore this research gap that could lead to theory extension. We analyze consumption behavior with respect to traditional retail markets through an empirical analysis, thus overcoming limits in previous research. We empirically analyze policy effects of traditional retail market projects supported by the Korean government. Research design, data, and methodology - We propose a traditional retail market improvement plan via the relation between cause and effect resulting from the analysis. More specifically, logit analysis was carried out with 1,754 consumers in 16 cities nationwide. In order to analyze consumer consumption behaviors nationwide, the probability was analyzed using a logit model. This research analyzes the link between support and non-support by the Korean government using binary values. The dependent variable is whether Korean government support is implemented; the binomial logistic regression is used as the statistical estimation technique. The object variables are:1 (support) or 0 (nonsupport), and the prediction value is between 1 and 0. As a result of the factor analysis of questions related to attributes of service quality, four factors were extracted: convenience, product, facilities, and service. Results - The results indicate that convenience, product, and facilities have a significant influence on consumer satisfaction in accordance with the government's traditional retail market support. Additionally, the results reveal that convenience, product, facilities, and service all have a significant influence on consumer satisfaction in a traditional retail market's service quality and consumer satisfaction. Finally, the analysis indicates that the highly satisfied traditional retail market customer has a significant influence on revisit intention. Moreover, the results reveal that the highly satisfied traditional retail market customer has a significant influence on recommendation intention. Conclusions - This research focused on consumers nationwide to measure policy effects of traditional retail markets compared to previous research that focused on one traditional retail market or a specific area. We verified the relationship of service quality and customer satisfaction and consumer behavior based on service quality theory. The results indicate that consumer satisfaction of traditional retail markets supported by service quality factors has a significant impact. In a concrete form, the results indicate that these effects are from facility modernization projects and marketing support projects of the Korean government. The results also imply that these facility and management support effects from the Korean government have been consistent. We realize that the Korean government has to selectively support traditional retail markets in major cities and small and medium-sized cities. To that end, the Korean government needs to select a concentration strategy for the revitalization of traditional retail markets.

Purpose - This paper aims to investigate the mediating effects of relationship fairness factors between franchisor's support services and performance(re-contract intention) in food service franchise. More specifically, fairness was measured into distributive, procedure, interaction, and information, franchisor's support service was divided into pre-start support services (initial support services) and post-start support services (continued support services), and performance (re-contract intent) was measured using 3 items such as re-contract, contract extension, and recommendation. Research design, data, and methodology - The population for the survey is the head of franchises in the metropolitan area (Seoul/Gyeonggi), which operates a restaurant franchise, and samples included a wide range of overseas/domestic brands and regions. The survey was conducted from August 1 to September 30, 2018 through the survey agency. The survey was conducted together with a telephone interview and a direct visit by the investigator. A total of 205 questionnaires were collected and retrieved, 4 questionaires containing missing information were excluded and 201 responses were used for analysis. Results - The results shows that franchisor's initial support services have significant positive effects on procedural, interpersonal, and informational relationship fairness, and continuous support services have significant positive effects on distributive, procedural, interpersonal, and informational relationship fairness. This study also shows that informational and procedural fairness have significant positive effects on performance(re-contract intention). Finally, continuous services a significant positive effect on performance(re-contract intention). Conclusions - The results show that franchisor make a manual, and should improve fairness through regular investigation whether support services was executed as promised in the manual after franchisee operation. In addition, information fairness and procedural fairness have been shown to increase performance(re-contract intention). These results mean that the franchisor's headquarters should provide product and service support for the merchant in accordance with the manual and management policy to reduce asymmetry in information and improve procedural fairness to enhance performance(re-contract intention).

Korea is worldwide top manufacturer of offshore plant industry, while shown weakness in high-valued offshore plant service industry (OPSI). The governmental support policies and studies for fostering programs are centered on shipbuilding and engineering sector. On the other hand, offshore logistics service sector among the programs is neither included as governmental fostering support sectors nor ever-studied. Domestic shipping and logistics companies have many experience of handling various project, heavy-lift cargo and even super blocks on shipbuilding industry. However they are faced with lack of appropriate heavy carrier and others. So for their successful entering into offshore plant logistics market, systematic preparation, studies and supporting policies are highly recommended.

Background: To improve the support low-income individuals' medical expenses, it is necessary to think about ways to enhance the Catastrophic Health Expenditure Support Program. This study proposes expanding support criteria and changing the income standard. Methods: This study conducted simulations using national data from the National Health Insurance Service. Simulations performed for people who have used health services (n=172,764) in 2022 to confirm the Catastrophic Health Expenditure Support Program's size based on changes to the subject selection criteria. Results: As a result of the simulation with expanded criteria, the expected budget was estimated to increase between Korean won (KRW) 13.2 (11.5%) and 138.6 billion (37.4%), and the number of recipients increased between 41,979 (48.9%) and 150,317 (76.1%). The results of the simulation for the change in income criteria (applied to health insurance levels below the 50th percentile) estimated the expected budget to increase between KRW -8.9 (-7.8%) and 55.6 billion (15.0%) and the number of recipients to increase between -8,704 (-10.1%) and 41,693 (21.1%) compared to the current standard. Conclusion: The 2023 Catastrophic Health Expenditure Support Program's criteria were expanded as per the 20th Presidential Office's national agenda to alleviate the burden of medical expenses on the low-income class. In addition, The Catastrophic Health Expenditure Support Program needs to be integrated with other medical expense support policies in the mid- to long-term, and a foundation must be prepared to ensure the consistency of each system.

본 논문은 현재 한국 해군 잠수함 선석할당방법을 반영하여 기존의 잠수함 선석 할당계획문제를 확장하고 해당문제를 해결하는 정수계획모형을 제안한다. 기존의 잠수함 선석 할당계획 문제는 정박 중 선석 이동과 지원업무 실패를 최소화하면서, 잠수함이 필요한 지원업무가 가능한 선석에 잠수함을 할당하는 것이다. 반면, 한국 해군에서는 선석이동과 지원업무실패 최소화뿐만 아니라 부두 가용자원을 고려하여 잠수함이 요구하는 지원업무의 일정을 최대한 보장하면서, 선석을 할당한다. 따라서 본 논문은 한국 해군의 운용상황에 맞게 기존의 잠수함 선석 할당계획 문제를 확장하고, 부두가용자원의 특징과 잠수함 지원업무 일정의 조율을 포함하는 모형을 제시한다. 제안하는 모형은 선석이동 횟수, 지원업무 지원 실패 횟수, 잠수함 지원업무 요구 일정 조율 횟수를 최소화하는 것을 목적으로 한다. 본 모형의 검증을 위해서 한국 해군의 상황을 바탕으로 고려한 가상의 데이터로 실험을 수행하여 기존의 잠수함 선석 할당계획 문제와 비교·분석한다.
