  • 상호운용성과 협력은 디지털 도서관에 있어서 필수요소가 되고 있다. 이의 대표적인 사례인 유럽 도서관(TEL)은 유럽 34개 국가 도서관의 통합 서비스를 목적으로 개발된 범 유럽 도서관 서비스로서, 이를 구축하기 위한 프로젝트의 이름이기도 하다. TEL은 각각의 국가 도서관이 가지는 장서의 방대함, 소장본의 문화유산적 가치, 국가기관으로서의 신뢰성, 디지털화를 통한 부가가치 창출에 우선권을 가짐으로써 유럽 각국의 문화적 이질성을 공유할 수 있는 기반을 마련하였다. 기술적인 면에서 유럽 도서관은 이질적인 장서 및 도서관 간의 상호운용성을 보장하는 발전된 방안을 개척하였다. 이 연구는 유럽 도서관 실현을 위해 진행되었던 출판사와의 관계, 메타데이터, 검색, 운영현황을 고찰함으로써 국가 도서관 간 통합 서비스 구축의 사례를 제시하고자 한다.

  • 인터넷 트래픽이 증가하면서 이들을 기존 음성망에 효율적으로 수용해야 하는 문제는 기존 통신사업자들에게는 중요한 현안문제이다. 차세대 교환망의 모습은 인터넷 서비스 등의 데이터 트래픽을 기존 음성망과 연계하는 통합망의 형태로 이루어질 것이며, 망의 구성 시기나 사업의 성격에 따라 너무나 다양한 모습들로 제시될 수 있다. 기존 회선기반 통신망을 패킷기반 통신망으로 진화하는 전략은 그 적용 위치에 따라서 크게 두 가지로 구분할 수 있는데, 먼저 액세스망을 먼저 패킷화하는 기술로서 VoDSL을 적용하는 방법과 중계망을 먼저 패킷화한 후 액세스망으로 패킷화를 확대하는 SoftSwitch 기술 적용 방법이 있다. 본 논문은 음성 서비스와 DSL 인터넷 접속 서비스를 제공하는 현재의 통신망 환경에서 음성 서비스를 액세스망에서 패킷화하는 기술인 VoDSL을 적용하여 패킷기반의 차세대 통신망 구축에 바람직한 기술을 도출하고, 또한 현재를 기준으로 기존 음성통신사업자의 관점에서 차세대 교환망을 실현하고자 할 때, 현실적인 해결책들을 위주로 필요한 핵심 기술인 VoDSL 서비스를 제공하기 위한 방안에 대해 연구를 수행한다.

  • 범용 그래픽 처리 장치(General Purpose Graphics Processing Unit, GPGPU)는 최근 고성능 컴퓨팅에서 중요한 역할을 함으로써, 여러 클라우드 서비스 공급업체들은 GPU 서비스를 제공하기 시작했다. 컨테이너를 사용하는 클라우드 환경에서 대부분의 클러스터 오케스트레이션 플랫폼은 정수 개의 GPU를 작업에 할당하고 다른 작업과 이를 공유하는 것을 허용하지 않는다. 이 경우 작업이 GPU에서 코어 및 메모리 등 자원이 집중적으로 필요하지 않다면 GPU 노드의 리소스 사용률이 저하될 수 있다. GPU 가상화는 응용의 동시 수행을 가능하게 하며 자원을 공유할 수 있는 기회를 제공한다. 하지만 응용의 동시 수행 성능은 동시 수행되는 응용의 특성과 노드 안에서 자원 경쟁으로 인한 간섭에 따라 달라질 수 있다. 본 논문은 컨테이너 오케스트레이션 플랫폼인 쿠버네티스(Kubernetes)를 기반으로 다중 서버 생성 및 실행을 통하여 GPU를 공유함으로써 발생할 수 있는 간섭을 측정하기 위한 프레임워크를 제안한다. 본 프레임워크를 통해 다양한 스케줄링 방법으로 GPU에서 여러 작업을 실행함으로써 이에 따른 성능 변화를 조사하였으며, 이를 통해 GPU 메모리 사용량 및 컴퓨팅 리소스만 고려해서는 최적의 스케줄링을 할 수 없음을 보인다. 마지막으로 해당 프레임워크를 사용하여 응용들의 동시 실행에 따라 발생한 간섭을 측정한다.

  • The purpose of this research is to seek for efficient method of health improvement program for the old and to offer basic material for the development of community's public health service. This study investigated into the yangseng life level of the old and the factors which affect their yangseng life, and was to offer basic materials for oriental medicine-based health improvement plan which is appropriate for each community. The 818 surveys were conducted upon the old who are above 65 and who live in Jeollabukdo, and the results from the survey are as follows ; 1. The rural area showed more percentage of old people, the old who live alone and who have job compared to urban area. More people in rural area were found to live at their own expense. Additionally, there were more people who had high education in urban area and who have disease in rural area. 2. The total yangseng level of recipients was 94.20, and the average was 3.25. The average of urbanite was 3.26 and it was 3.23 for who live in rustic area, but there found no significant difference. All the old live in both urban area and rural area showed the highest score in morality yangseng and lowest in sex-life yangseng. 3. There found no difference upon regions, but the recipients show high yangseng level when they are male, have spouse, live with them, have factors including high education background, job, religion and hobby, or have confidence in their health. They also show high yangseng level when they do not have any disease in progress. 4. According to the results of general traits and yangseng level of each category, the old who live in urban area show higher exercise yangseng level than the one in rural area, and there is no significant difference upon the region in other categories. There were some cases which general traits and regional characteristics mutually affected each other. In conclusion, the yangseng level of the old is affected by individual traits and habits rather than the regions in which they live. The old who live in rural area are required to focus on exercise more, since the exercise yangseng level of them were lower than the ones of urban area. Moreover, there were some cases which general traits and regional characteristics mutually affected each other, so it requires further in-depth study about the correlation.

  • Reaching up the present from the past, the design was reflected in our life, thereby having brought about great development in the aesthetic harmony or functional part. In the present era, it is advancing in order to seek for the better direction without being satisfied with formativeness. What comes to represent it is UX design, namely, user-experience design. If a user has confusion in using product or environmental facilities, or if a user needs to utilize by analyzing function, this cannot help being inconvenient. Only what a user's behavior is caused by which the cognitive and sensitive attributes interact without inconvenience can be said to be design for a user. Given explaining easily, UX implies to design and develop the designed product or space from the position of a client who uses. Also, it also implies to offer service of being satisfied. For one example, a work can be said that distributes logo to the upper part of web site. That is because of allowing client to be much confused if logo is distributed to the different position. The designed web site in consideration of user's position is developed much now. However, it is the real situation of being still much insufficient in the public facilities that have UX characteristics amid the living environment. There is great interest in UX of the public facilities. However, there are many cases of facing mostly for the first time. The understanding level is thought to be much different. This study examines about a concept of UX design, and about UX design, which considered from the user's position, and analyzes a case. Thus, the aim is to suggest good directivity in designing by efficiently approaching UX that can be difficult theoretically.

  • The purpose of this study was to investigate use and purchase behavior of sleeping wear for summer. Subjects in this study were composed of 591 males and females aged from twenties to fifties, living in Taejon and Chongju. For data analysis, descriptive analysis, $\chi$$^2$-test, t-test, ANOVA, and factor analysis were used. The results are as follows. First, subjects used sleeping wear(a night gown and pajamas), and home wear(T-shirts and sweat suit with zippered top) with similar rates. The subjects, who are females, married, older and have professional jobs, owned sleeping wear such as a night gown and pajamas more than home wear. Also, the mean of using pajamas was the highest, and they were satisfied with them more than others who didn't wear them. Second, one-third of consumers purchased sleeping wear once a year in a specialty store. Consumers mainly searched for information regarding sleeping wear in the display section. Most consumers weren't influenced by others when they made their purchases. When consumers decided to purchase a product, they considered six criteria such as fabric/management, wearing/fitness, esthetic, service, symbolic status, and economic for evaluating. Among them, the factor wearing/fitness was considered the most important. These results imply that consumers would be conscious of sleeping wear even though sleeping wear and home wear are used interchangeably. In addition, consumer behavior concerning sleeping wear is different from their characteristics such as sex, age, occupation, the level of education, and marital state. Therefore, the markets with sleeping wear would be able to be segmented based on consumers’characteristics. Also, marketers should focus on distribution channels to reform the markets of sleeping wear, that is, they may offer products in specialty stores. Additionally, market managers would be able to concentrate on visual merchandising in stores in order to increase brand awareness and market share.

  • 본 논문은 앞으로 산업의 많은 부분에 영향을 미치게 될 ITS(Intelligent Transport System)의 주요 통신 수단인 단거리 전용 통신(DSRC : Dedicated Short Range Communication) 시스템의 성능을 매체 접근 제어(MAC : Media Access Control)단에서의 전송 효율을 분석함으로써 평가하였다. 현재 DSRC는 자동요금징수(ETC : Electric Toll Control)과 버스정보시스템(BIS : Bus Information System) 등의 전송 효율이 시스템이 미치는 영향이 극히 낮은 시스템에 사용되고 있으나, 향후 첨단 운전자 정보 안내 시스템(ADIS : Advanced Driver Information Systems) 또는 첨단차량 및 도로 시스템(AVHS : Advanced Vehicle Highway System) 등과 같은 고도화된 시스템으로 진화할 경우 DSRC의 주요한 매체인 적외선(IR : Infra Red) 방식과 주파수(RF : Radio Frequency) 방식의 MAC 프레임 속성에 따른 서비스의 질은 급격히 변화될 것이다. 따라서 본 논문에서는 그 특성을 전송 속도에 따른 시간의 함수로 구성하여 분석함으로써 이후 다양한 ITS 서비스에 활용할 수 있는 지표를 제공하고자 하였다.

  • Purpose - The domestic franchise industry has made significant contributions to industry such as investment, employment, and community economy development, facilitating growth potential. The franchise industry provides management knowhow transfer between parent companies and franchisees as per contracts addressing use of business signs, franchisees' independent position, franchisor support, and royalties to be paid to the franchisors. However, many franchisors lack management knowhow and provide insufficient support because of poor control of franchisees and not having a systematic approach to support. This results in dissatisfied franchisees and failure to establish long-term relationships. Few studies have examined relational commitment and/or re-contract intention by support resources between franchisors and franchisees, despite a considerable output of theories and studies of the growth of the franchise industry. The purpose of this study, therefore, was to examine the effects of the ability to provide resources on relational commitments and re-contract intention, and to suggest causal relationships and implications. Research design, data, and methodology - The subject was domestic franchisors registered with the Association of Franchise with more than 50 franchisees. Franchisees under contract for 2 years and considering re-contract of their franchise 2 years later were used. The subjects totaled 300 franchisees in Seoul. A questionnaire survey was used to investigate the subject of franchisees' concessions during the 10 days from November 21, 2013 to November 30, 2013. After excluding 16 surveys with poor answers, 284 responses were finally used. Four areas and 44 questions were used. A nominal scale was used for four common characteristics questions including gender, ages, educational background, and franchise managing time. Questions regarding ability, relational commitment, and re-contract intention made use of a Likert 5-point scale. Data coding and data cleaning were used. SPSS 18.0 was used as follows. First, frequency analysis was done to investigate demographic characteristics. Second, exploratory factor analysis was done to verify validity of testing tools, and Cronbach's α coefficient was used to verify reliability. Third, correlation analysis and multiple regression analysis were done. An exploratory factor analysis was done to verify validity of concepts. A correlation analysis was done to test relationships between the variables, and multiple regression analysis was done to verify franchisor's ability, franchisees' relational commitment, and re-contract intention. Results - The following were the outcomes. First, store operation management, finance operation management, and human resource management affected the calculated bond. Second, store operation management and finance operation management affected the emotional bond. Third, store operation management, finance operation management, human resource management, and marketing management affected the prescriptive bond. Fourth, calculated bond and prescriptive bond had an effect on re-contract intention. Conclusions - As stated above, in franchise management, parent companies' offer and instruction of core competence to their franchisees as an information resource could improve the relational bond by helping them grow together through the resource sharing. Consequently, core competence factors were promoting factors that could improve franchisees' re-contract intention for a long time.
