이동에이전트를 위한 이동객체(mobile agent)와 이를 지원해주는 이동객체서버(mobile object system)를 설계하고 이러한 요소들을 제어하고 관리하는 이동객체 시스템(mobile object system)을 Java로 구현한다. 또, 시스템 내의 이동객체를 비롯한 모든 객체들간의 객체 요청(object request)을 유연하게 중계하고 이들간의 통신을 담당하는 ORB (Object Request Broker)를 TCP/IC상에서 Java 로 구현하고 이동 에이젼트 시스템을 쉽게 구측할수 있는 앱스트랙션(abstraction)과 API를 제공한다. 이 시스템은 네이밍 서비스(naning service)와 푸쉬형 이벤트 서비스(push-event service)등을 기본적으로 지원한다.

최근 스마트폰 확산과 함께 모바일 시장이 개방적인 PC진영으로 편입되면서 ICT 산업구조가 복잡한 개방적 생태계로 재편성되고 있다. 이에 본고에서는 가치 네트워크(Value Network) 관점에서 타 산업 사업자간 상생적 협력관계 구축을 통한 수익배분 모델 등 주요 글로벌 ICT 리더들의 사업전략을 분석하고, 단말 및 서비스 플랫폼을 중심으로 하는 새로운 ICT 생태계의 진화방향을 전망하고자 한다. 특히 앱스 토어를 기반으로 하여 단말 플랫폼을 확장하는 애플의 전략 과 웹을 기반으로 하는 서비스 플랫폼을 통해 이용자의 접점을 확장하는 구글의 사업전략을 비교 분석하여 향후 글로벌 ICT 산업의 전망과 시사점을 제시하고자 한다.

최근 다양한 기능을 수행할 수 있는 모바일 단말 개발이 확산됨과 함께 모바일 단말기를 이용해 회사 업무를 처리 할 수 있는 모바일 오피스를 구축하는 기업이 빠르게 증가 하고 있다. 모바일 오피스에 사용되는 단말기에는 회사 업무 처리가 가능한 업무 시스템 및 업무 기능을 포함하는 앱스(Apps)가 설치 되어있으며, 이를 통해 외부에서 네트워크를 통해 업무를 수행하게 된다. 다양한 단말을 통한 내부 시스템의 접속 및 외부에서부터 기업 내부 망으로 접속하는 것을 허용하게 됨에 따라 내부정보유출 시스템의 적용 범위를 모바일 단말 사용자에게 확대할 필요가 생겼다. 효율적인 업무 운영이 가능하면서, 안전하게 수행 가능한 모바일 오피스 운영을 위해 직원의 프라이버시 보호가 가능하면서 내부 정보 유출을 방지할 수 있는 방안에 대해 연구 해 보고자 한다.

This paper presented a mobile application program to help eye movement with mobile devices. It helps to strengthen ocular muscles and improve visual acuity. Users can easily access the program of eye movement type of app program in mobile devices. There were some papers which studied on the eye movement and showed efficient eye movement method for improvement of visual acuity. So here presents programming codes to help eye movement with some specific patterns from some papers and it was implemented by HTML, CSS and javascript. To convert web code to app code, appspresso tool was used.

Statistics are often used to test two samples if they have been drawn from the same underlying distribution. In this paper, we introduce several well-known distribution-free tests to compare distributions and conduct an extensive Monte-Carlo simulation to specify their behaviors. We consider various circumstances of when two distributions vary in (1) location, (2) scale, (3) symmetry, (4) kurtosis, (5) tail weight. A practical guideline for two-sample goodness-of-fit test is presented based on the simulation result.

This thesis attempts to investigate and analyse the architectural characteristics of catholic churches in Gangwon province built in the 1950s. Catholic churches built at that time in Korea had many similarities basically since they were supported by UN forces after the Korean War and were established by priests connected to the Missionary Society of St. Columban. The results of study are as follows. In location, Except one catholic church, the catholic churches preferred low and gentle hill. In layout axis, catholic churches at Youngseo area preferred the north-south layout axis, whereas those at Youngdong favor the east-west layout axis. In approach, most of catholic churches around the Youngseo and Youngdong areas preferred entering the front entrance with a bell tower, whereas three of them at Youngdong did entering the front entrance with a bell tower around the rear corner. In floor plan, catholic churches at Youngseo preferred symmetry, whereas those at Youngdong preferred asymmetry. And every floor plan of catholic churches is rectangular type with transepts except one semicircular type. In apse shape, catholic churches in the Youngseo area preferred non-extruded types like a straight wall, whereas those in Youngdong have extruded types. Every catholic churches have no crypt under ground except one at Gangreung. Except one at Sokcho, every catholic church in this study has choir space in half story.

Today, Software as a Service(SaaS) is being recognized as a key means to enable the innovation of software distribution. Despite the increase in the interest in SaaS, individuals as well as businesses are not yet making an extensive use of it. This research is aimed at identifying and analyzing the antecedents of intentions to use SaaS. We proposed a research model to predict an individual's intention to use SaaS based on the Technology Acceptance Model(TAM). To this end, we conducted a questionnaire survey in which actual software users participated. An empirical analysis has been performed to test the reliability and validity and the hypotheses using SPSS and AMOS software packages. The results of the analysis revealed that functionality, interoperability and economic benefits have positive effects on the intention to use SaaS, while system quality has no significant effect on the behavioral intention. We discussed practical as well as academic implications, and provided research directions.
