서비스 지향 구조(SOA, Service Oriented Architecture)는 인터넷상에서 구현되는 웹 서비스의 출현으로 인하여 급속도로 발전하고 있으며 활성화 되고 있다. 인터넷환경이 발달함에 따라 분산되어 있는 자원에 쉽게 접근할 수 있고, 시맨틱 웹이란 기술로 보다 광범위하게 지식과 자원을 표현할 수 있다. 그러나 웹 서비스의 사용과 이에 따른 지식과 자원을 보호하기 위해서는 정보보안이 필수 요건이나 웹 서비스의 활성화에 비하여 웹 서비스의 보안 표준이나 웹 서비스 보안이 미비한 상태이다. 본 논문에서는 이러한 요건을 충족하기 위하여 협업적 제품거래(CPC, Collaborative Product Commerce) 서비스를 위한 분산 접근제어 프로세서를 제안한다. 각각의 CpC 서비스마다 독립적인 접근제어 프로세서를 설계하기 위하여 기본적으로 사용할 수 있는 웹 서비스 표준과 기본개념에 따라 분산되어 있는 각각의 웹 서비스를 위한 분산 접근제어 프로세서를 설계 한다.

This study aims to develop the concept of innovation models with the marketing channel construct approach, marketing innovation, product segmentation, and customer insight; as well as improvements to the theory of resource-based combined with the method of service-dominant logic. This study approach is based on quantitative descriptive conducted with three stages of testing scenarios. The first test is the mapping of the innovation model construct through testing the validity and reliability with the moderation of customer orientation variables. The second scenario examines the relationship of influence between the independent variables on the dependent variable of 29 hypothetical analysis equation modeling. The unit of analysis was conducted on 497 SMEs involved in the food and beverage sectors, with the criteria being SMEs must have a rating of 4-5 points on the Go-Food applications software. The results shown that: 1) the construct used to develop an innovative model both directly and via moderation is positive and significant; 2) Through a complicated relationship that involves all components of the variable, it outlines a positive and significant effect except for the path of analysis (μ5). The theoretical and managerial implications state that the service-dominant logic approach and resource-based view theory have extreme reliability and interrelations.

Purpose: This study exploresthe impact of e-service quality (e-SQ) on satisfaction, trust, and loyalty within Chinese online travel retail distribution agencies (OTRDAs) using the SOR (stimulus-organism-response) model. In addition, this research examines the mediating roles of satisfaction and trust in the relationship between e-SQ and loyalty. In the model, e-SQ encompasses four sub-dimensions, such as information, efficiency, reliability, and security. Research design, data, and methodology: Data were collected from 401 respondents through an online survey. The data were analyzed using SPSS 25.0 and SmartPLS 4.1 to test the relationships among the variables. Results: The findings reveal that information, efficiency, reliability, and security positively influence satisfaction and trust. Both satisfaction and trust, in turn, significantly enhance loyalty. Mediation analysisindicatesthat satisfaction and trust partially mediate the relationship between e-SQ and loyalty. Conclusions: The study highlights the direct effects of e-SQ components on satisfaction and trust, as well as their indirect effects on loyalty within the OTRDA framework. Notably, trust exerts a stronger influence on loyalty than satisfaction, underscoring the importance of trust as a mediator in the satisfaction-loyalty relationship. Consequently, customer loyalty programs for OTRDAs should prioritize trust evaluations alongside satisfaction measures.

본 연구는 교육기반 작업치료 서비스 전문가가 사용하는 중재모델, 중재장소와 중재시간, 중재모델 선택시 고려사항, 중재모델과 중재 영역 간에 상관관계를 알아보기 위해 특수교육지원센터에 근무하고 있는 작업치료사와 작업치료를 전공한 치료교사를 대상으로 설문지를 발송하고, 회수한 총 46부를 분석에 사용하였다. 연구결과 첫째, 학생의 수행 기술을 향상시키는데 초점을 둔 개별치료 모델을 자주 사용하였다. 둘째, 아동수행을 향상시키는 중재모델과 다른 팀 전문가에게 작업치료의 중요성을 인식시킬 수 있는 모델로 개별 치료를 선택하였다. 셋째, 중재모델을 선택하는 요인으로 수행구성요소의 결함과 팀 책임자의 마인드를 들었다. 넷째, 중재모델의 효과성에 대한 학교작업치료사의 의견과 적용시간, 중재 영역과 중재모델 적용시간 간에 유의한 상관관계는 나타나지 않았다. 연구결과를 종합해 보면 학교기반 작업치료사는 여전히 의료모델에 가까운 중재모델을 사용하는 것으로 나타나 학교기반에 효과적인 중재모델을 개발하고 적용하는 연구가 필요할 것이라 생각된다.

The purpose of this study is to elicit influential factors on accepting IPTV services and define the casual relationship between the factors, and "user satisfaction", "re-use intention", "stranger recommendation intention", in an attempt to provide useful guidelines to IPTV carriers, contents providers and equipment makers for their forming IPTV service models and marketing strategies. For this end, the theoretical background of this study has been brought from relevant literature, and theoretical study models have been established by logical reasoning of the interrelation among diverse components. Then, the established models have been analyzed by using statistical packages "SPSS(12.0), LISREL(8.72)". Finally theoretical and practical significance and future study direction have been suggested. To make sure of effective validity of IPTV service adoption models above, empirical studies should be made continuously. And then vertical and horizontal studies at a specific point would show ever-changing causal relationship, helping to promote financial outcome of relevant companies and organizations.

Customer value is the source for competitive advantage of online businesses such as Internet shopping malls and portal service. It is important to analyze the relationship between customer value and repurchase in order to provide a guideline of successful online business. The purpose of this paper is to get answers for the following questions. First, what are key components of customer value in online business? Second, What difference exists in the importance or expectance of customer value and its current service level of online business? Finally, what influence relationships exist in customer value and repurchase intentions? Data were collected from 615 respondents who experienced purchase on the Internet shopping malls. This paper developed and empirically tested a model representing the relationships between customer value factors and repurchase intentions as well as difference between the importance of customer value and its service level. The findings here suggested that the service level of customer value was significantly lower than its importance, and customer value factors positively affected the repurchase intentions. Specifically, economy and trust/responsiveness value factors directly affected the repurchase intentions while other factors such as convenience, speed, personalization, community, and emotion value indirectly affected it through trust/responsiveness.

최근 인터넷 서비스의 활용은 다양한 정보와 동시에 개인에 적합한 서비스를 제공하기위한 노력들로 이루어지고 있다. 이에 본 논문에서는 인터넷 멀티미디어 서브시스템을 기반으로 서비스 통합 과 개인화를 제공하는 웹서비스 활용 모델을 제시하고자 한다. 이러한 서비스 통합과 개인화를 위해 서비스 사용자 정보 분석 및 개인화 서비스 구성요소 추출과정이 요구되며 이를 위해 개인 서비스 제공 정책 수립이 필요하다. 이러한 과정을 통해 기존 서비스와 외부 서비스들 간의 효율적인 통합을 제공할 수 있으며 신규서비스 모델을 구축하여 서비스 이용자에 대한 보다 세밀한 서비스 제공이 가능할 것이다.

This study introduces the system dynamics model that simulate total operational availability when 10 equipments made of 3 major components are serviced under the constrains of the maintenance capacity level and the number of spare parts. This simulation is designed on the base of reliability engineering concept so failures of components happens with the rule of engineering factors like the mean time between failure(MTBF) of component and the next failure time of one component is effected by the conditions of other components. We analysed availability of 10 equipments under 121 constrains and executed multiple regression analysis with the simulation result. The analysis provide the managerial insight in the service fields with operation many equipments.

The standard of the allowed stress in designing components such as shafts used in machinery and aircraft should be determined. It is very important to estimate fatigue strength of a component analytically, because service stress of the components is usually under the level of its fatigue limit. Improving the fatigue strength of each component in machinery is essential for high performance, lightness, and endurance. Surface treatment of components is widely used for these purpose. In this research, the fatigue behaviors of SCM415 steel and carbonitried SCM415 steel are examined. In the analysis of the fatigue behaviors of the carbonitrided SCM 415 steel, we propose a modified fatigue strength evaluation model and modified formulae.

교통사고 예방과 교통난 완화를 목적으로 도입된 지능형교통체계(ITS; Intelligent Transport System)는 민간영역의 다양한 서비스들과 결합하여 새로운 생활양식을 창출하는 종합 서비스의 개념으로 발전하고 있다. ITS 서비스에 이용되는 여행자단말장치도 별도의 장치라기 보다는 기존의 이동전화기, PDA, PC, KIOSK 등을 통해 구현되고 있으므로, 이러한 단말장치들이 갖춰야 할 ITS적인 요소들을 검토할 필요가 있다. 이에 본 연구는 민간사업자들이 ITS서비스를 고려하여 단말장치를 개발할 수 있도록 국가 ITS아키텍쳐를 근간으로 여행자장치형 구성요소를 구현하기 위한 구축단위들의 프레임워크를 UML로 모델링하였다. 모델링과정은 소속서브시스템파악 구축단위/기능명세 일반화, 정보/기능관점 참조모델작성, 참조모델의 UML모델링 등의 4단계를 따른다.
