  • Construction industry has a relatively higher industrial accident rate than other domestic industries. Thus, to reduce the accident rate, researches on the methodology of worker's safety education combined with new technologies like IT technology have increased. In the light of workers' safety information provision, this study develops a VR(Virtual Reality)-based construction site using the BIM(Building Information Modeling) data. The target structures and geographical features are included in the VR-based construction site where the construction machinery model and worker model are also created using a game engine. For highly effective provision of safety information, video clips with suitable captions corresponding to working processes were made with proper screen directing. They should be appropriately connected to correct worker's operations to improve the work commitment level, sense of reality and inducement of interest. From this scenario, the 3D VR-based construction site, which can be experienced through a VR equipment, was created and in the same platform, the safety information was provided by the video clip combined with the suitable captions. Although the real construction site involves various requirements depending on field situation and the expertness and experience of workers are not consistent, the developed safety information provision based on the VR construction site is expected to effectively reduce the incomplete factors leading to construction accidents by improving the worker's perception of workplace safety.

  • An ecological learning center is defined as a place which can establish the correct relationship between human and environment. Human can learn ecosystem and importance of environment throughout observation of nature and participation in program of ecological learning center. The most important aspects of ecological learning center planning are to reflect on user's demand and preservation of ecosystem. The prime goals of this study is to analyze user's characteristics in the Young Wheol Mulmurigol Ecological Learning Center. The second goal of this study is to find out the satisfaction model based on user's perceived performance of each program and facility in the center. For this study, questionnaire survey with 204 individuals was completed. The data from the questionnaire were analyzed statistical method by SPSS. There are several significant results from the study as following First, this ecological learning center as a newly operating facility is used not for educational purpose but for resting and relaxation purpose. It is due to that the most of users in this center are package tourists with historic scenes. Second, user's perceived performance evaluated by 23 attributions of programs and facilities, and these attributions could be classified by 5 factors such as environment friendly design, educational function, preservation of environment, provision of various bio-top and provision of resting area. Third, the user satisfaction model indicates that user satisfaction is depended on various factors such as preservation of environment, provision of various bio-top, provision of resting area. Among these factor affecting the satisfaction, provision of various bio-top is the most influence on user satisfaction.

  • Provision of higher throughput without sacrificing consistency guarantees in replication systems is a critical problem. In this paper, we propose a novel approach called Bidirectional Chain Replication (BCR) to improve throughput in traditional Chain Replication (CR) through better utilization of computing and communication resources of the chain. Unlike CR where the whole replicated data store is treated as a single unit, in BCR the replicated shared data at each server in the chain is split into two disjoint Logical Partitions ($LP_1$, $LP_2$). This forms two chains running concurrently on the same hardware in two opposite directions; the first chain ($CR_1$) exclusively manipulates data objects in $LP_1$, while the second chain ($CR_2$) exclusively manipulates data objects in $LP_2$, therefore, conflict is avoided and concurrency is guaranteed. The simultaneous employment of these two chains results in better utilization of hardware in the sense that the two chains can evenly share the workload, hence, throughput can be improved without sacrificing consistency. Experimental results showed an improvement of approximately 85% in throughput of BCR over CR.

  • Considering the need for quality health information and resultant health care services in any society, this study was carried out to look into the status of library and information resources and services provided by medical libraries in Enugu State, Nigeria. The main objective of the study was to find out the information resources and services available for medical library users towards quality health care provision. Five (5) medical libraries of major teaching hospitals were used for the study with 980 registered users as the study population from where 245 users were sampled. Observation checklist was used to collect data on resources while questionnaire was used to collect data from the respondents on the services provided. The Medical Library Association Standard guided the analysis of data from observation while frequency counts and mean scores were used to analyze data from the questionnaire. Major findings showed that even though some of the required resources and services are available and provided the medical libraries, most of the required resources and services are not adequately provided by these libraries.

  • Increasing affectability of high-speed Internet and convenient access devices has made the Internet a major source of information search and sharing. As the provision of information has rapidly becomes an important and viable business model, the objective utility and marketability of information contents have become a focus of interest among many academicians and managers. Researchers have traditionally focused on the design of the interface, availability of resources, network accessibility, the format of web sites and their underlying systems. However, the usefulness of contents has been left as a little explored issue. To correctly diagnose and pursue the viability of contents provision business a shift of perspective is required : a shift from technology-oriented perspective toward user-oriented perspective, and a shift from form and design focus toward content focus. This research attempted to analyze consumer-oriented information quality in a more systematic way by focusing on a limited domain travel-related information contents. We proposed a relationship among consumers'behavior, characteristics of information, and the values of information measured by users. An empirical examination of the model was performed using a survey on Internet users in Korea. Implications are drawn for managers responsible for creating marketable contents.

  • 본 연구에서는 공동체의 삶의 기억 수집·보존·관리 체계 구축 지원이라는 정책 과제를 기반으로 지역별 역사·향토자료 콘텐츠 수집과 공유, 큐레이션 서비스를 제공하는 공동체 기억보존의 중심지로서의 도서관 구축의 필요성을 제시하고자 하였다. 이를 위해, 문화원 및 지역기록관 등 지역 기반 자료를 서비스하고 있는 기관의 자료 수집 및 관리, 운영에 관한 현황을 파악하고, 도서관의 큐레이션 서비스 사례와 현황을 조사·분석하였다. 연구 결과를 통해 제안한 논의는 다음과 같다. 첫째, 문화원에서는 축제나 문화예술 행사, 문화예술 교육사업, 지역주민의 예술 활동 사업 등과 같은 사회교육 측면에서의 외부적 요구가 증대되고 있어 향토자료 조사 연구 및 발간을 비롯한 관리 업무까지 병행되어 관리가 쉽지 않은 실정이다. 따라서, 지역주민에게 정보서비스는 물론 문화프로그램 제공, 정보공유 공간 제공, 취약주민에 대한 서비스 제공 등 상당히 다양한 역할을 수행하고 있는 공공도서관에서 지역의 다양한 자료를 수집·보존하는 역할을 수행하는 것 이 필요하다. 기존 도서관의 경우 체계적인 자료 수집 방안을 구축하고 있기 때문에, 현재 문화원 및 각종 문화기관과의 협력을 통해 자료 관리를 원활히 운영할 수 있을 것으로 파악된다. 둘째, 도서관이 자료를 구축하고, 자료 이관이 어려운 자료가 많으며, 모든 자료를 도서관으로 집중하여 구축하는 것은 사실상 어렵기 때문에, 도서관과 지역 행정기관의 자료, 기타 유관기관, 개인의 자료를 모두 온라인 데이터베이스로 구축하여 자료에 쉽게 접근할 수 있고, 언제든지 도서관에서 열람할 수 있도록 모으는 방안이 필요할 것으로 파악된다.

  • 본 연구에서는 서울시 장기전세주택(SHIFT 이하 시프트)이 주변 아파트의 전세가격에 미치는 영향을 분석했다. 시프트 공급단지 5km 이내에 위치한 아파트들의 전세 실거래가 데이터를 이용하여, 시프트로 인한 주변 아파트 전세가격의 변화를 추정했다. 주요 결과는 다음과 같다. 첫째, 시프트 공급 이후 2-3km 이내 아파트들의 전세가격은 공급 이전을 기준으로 4.4% 하락했다. 반면 그 보다 근접한 1-2km 이내 위치한 아파트의 전세가격은 유의미한 변화를 확인할 수 없었다. 그 이유는 시프트 단지의 공급으로 주변지역이 함께 개발되면서 아주 근접한 아파트들의 경우 시프트 공급으로 인한 가격하락 요인을 입지환경 개선으로 인한 가격상승 요인이 상쇄한 것으로 해석된다. 시프트 단지별 분석에서는 천왕2지구1단지와 서초네이처힐 1, 3, 6단지에서는 주변 아파트 전세가격을 하락시키는 효과가 나타났다. 그러나 양재1단지, 묵동리본타워, 신내3지구2단지에서는 유의미한 효과를 확인할 수 없었다. 단지별 효과가 상이한 이유는 해당 지역의 전세수요와 시프트 공급물량 등의 차이로 인한 결과로 판단된다.

  • The purpose of this study was to investigate the factors associated with instrumental support (i.e., economic and practical support) from parents to their adult children. We examined both parents' attitudes toward instrumental support for adult children and parents' actual provision of instrumental support. From the data of the 2010 second National Survey of Korean Families, we selected 532 mothers and 524 fathers who were married and had at least one adult child aged over 25. Multiple regression analyses by the parents' gender showed that fathers were more likely to agree with instrumental support for adult children in general when they had unmarried children, had a lower household income level, had a lower evaluation of their socio-economic class, were satisfied with their own household economic situation, had positive attitudes toward caregiving for elderly parents, and were satisfied with their couple relationships. For mothers, they were more likely to agree with instrumental support for adult children in general when they had positive attitudes toward caregiving for elderly parents, were satisfied with their couple relationships, and perceived their child as someone to rely on in times of difficulties. Our analyses of the actual provision of support indicated that fathers tended to provide more support when they perceived that they were healthy, had unmarried children, were less satisfied with their household economic situation, had negative attitudes toward child-rearing, and reported a higher quality of parent-child relationship. For mothers, they were more likely to provide actual support when they were healthy, had unmarried children, had a higher level of household income, were financially preparing for later life, and less satisfied with their couple relationships. The findings of this study imply that it is imperative to distinguish the attitudes toward support from the actual provision of support and to also consider parents' gender in the literature on instrumental support for adult children.
