본 연구에서는 서지 정보를 확장하기 위한 방안으로 링크드 데이터를 선정하였다. 링크드 데이터는 웹 공간을 통해 공유 가능한 식별기호와 데이터 구조 및 링크 정보를 제공하기 때문이다. 특히 링크드 데이터는 서지 온톨로지와 결합하여 서지데이터를 확장시키는데 유용하다. 이에 링크드 데이터와 서지 온톨로지를 분석하고, 연계 가능한 링크드 데이터를 검토하였다. 그리고 이를 바탕으로 링크드 데이터로 구축된 기존의 전거 데이터 및 서지 데이터를 연계하였다. 이러한 실험적 연계를 통해 향후 링크드 데이터를 효과적으로 활용하기 위한 과제를 도출할 수 있었다. 즉, 1) 다양한 링크드 데이터 중에서 각 기관에서 적합한 데이터를 선정할 수 있어야 하며, 2) 선정된 링크드 데이터를 연계하기 위한 기준을 정립해야 하고, 마지막으로 3) 자관의 고유한 데이터를 개발하여 이를 다시 공유해 나가야 할 것을 제안하였다.

본 연구는 전거레코드 구축 및 공유를 위한 목적으로 진행된 'Social Networks and Archival Context' 프로젝트 사례를 통해 문화유산기관 간에 분산 소장된 역사적 정보원에 대한 통합적 접근과 기록에 대한 보다 풍부한 검색과 이해를 촉진하는 국가적 전거데이터베이스 구축의 필요성과 국내 적용 방안을 제시하였다. SNAC 프로젝트는 NARA 주도의 국제적 협력체 조직으로 전환되면서 지속가능한 운영체계를 확보하고 협력적 전거통제를 실현할 수 있었다. 또한 SNAC 전거레코드는 도서관에 비해 풍부한 생애와 역사에 관한 맥락 정보와 사회적·지적 네트워크 정보를 제공한다는 특징을 가진다. 사례분석을 통해 첫째, SNAC 처럼, 국가기록원이 주도하고 국립중앙도서관이 공동 오너쉽을 갖는 협력체가 개발을 주도하고 참여기관의 범위를 넓혀나가야 한다. 둘째, 협력의 방식에서 특장점을 가진 분야별로 분담하는 구조를 취하되, 두 기관이 참여하는 운영 주체가 주요한 의사결정을 하도록 한다. 셋째, 전거데이터 구축 시 다양한 포맷의 기술정보를 수집할 수 있는 확장가능한 오픈소스소프트웨어 개발, 기록관리 전거레코드의 구조와 요소로 설계, 전거레코드의 품질을 통제할 수 있는 기능 설계, 이용자 친화적 인터페이스 구축 및 콘텐츠적 요소가 반영된 플랫폼 설계가 필요함을 제시하였다.

This study is about the size and the number of toilets in the passenger ships. National regulations and other countries regulations were searched and analyzed. The toilets in the passenger ship, that are engaged in Busan City, Inchen City and Mokpo City were also searched and these present situation of the toilets were used with basic data of this study. Finally, we give a suggestion on the size and the number of toilets in the passenger ship.

Objectives: As the increasing of the length of the lifespan, more recent policy interest are concerned with how many years of life are lived without functional disability or activity limitation. We investigated the relationship between deprivation and activity limitation at the 251 local authority level. Methods: The data were derived from the 2010 Census 10% sample data. Crude and age-standardized activity limitation rates by gender at the ages of 50 or over and deprivation index were calculated. Mapping and multiple linear regression analysis were applied to explore relationship between area activity limitation and area deprivation. Results: There were considerable differences in activity limitation rate across the 251 local authorities. Age-standardized activity limitation rate in both male and female were strongly associated with the level of area deprivation. Especially, low social class, male unemployment, or non-apartment residents at the local level were strong positive association with local authorities' age-standardized activity limitation. Conclusion: More policy attention is needed for tackling regional inequality in activity limitation among older adults.

본 논문에서는 기존의 BTC 방법을 개선한 새로운 ABTC(adaptive block truncation coding) 방법을 제안하였다. ABTC 알고리듬은 화상데이터의 부분적인 특성에 따라 압축방식을 선택적으로 적용함으로써 높은 압축률로 우수한 화질의 재생화면을 얻을 수 있다. ABTC 화상압축방식은 압축 알고리듬이 간단하면서도 높은 압축률을 얻을 수 있는 특징이 있다. 이 알고리듬을 사용하면 칼라화상을 1.0(bit/pel)에서 2.26(bit/pel)의 데이터 부호율 범위내에서 임의로 코딩할 수 있으며 원래의 화상에 비해 화질의 큰 손상없이 높은 압축률 $1.3{\sim}1.5bit/pel$을 얻을 수 있다.

The purpose of this study was to explore the health and illness concepts of hospitalized preschoolers. The subjects were 52 hospitalized preschoolers from 3 to 6 grade in one general hospital. Data were collected through semistructured interviews by author. this study was conducted from Mar 2, 2000 to Jun. 30, 2000. Data were coded and categorized by content analysis. The results were as follows : 1. Hospitalized preschoolers's answers about health concepts were coded and then classificated to 7 categories(physical well-being, food, powerfulness, exercise, obedience to authority, cleanliness, sleep.) 2. Hospitalized preschoolers's answers about health behavior to maintenance health were coded and then classificated to 8 categories (food, obedience to authority, treatment, exercise, cleanliness, powerfulness, sleep, psychological stability). 3. Hospitalized preschoolers's answers about prevention of illness were coded and then classificated to 9 categories(food, treatment, obedience to authority, powerfulness, emotional stability, psychological stability, exercise, physical well-being, ability of social adaption). 4. Hospitalized preschoolers's answers about cause of illness were coded and then classificated to 3 categories(illness, trauma, food). 5. Hospitalized preschoolers's answers about treatments of illness were coded and then classificated to 9 categories(treatment, rest, emotional stability, sleep, psychological stability, food, obedience, exercise, powerfulness). 6. The levels of health and illness concepts in this sample were higher than those of the physical causality.

In the system of ciphertext policy attribute-based encryption (CP-ABE), only when the attributes of data user meets the access structure established by the encrypter, the data user can perform decryption operation. So CP-ABE has been widely used in personal health record system (PHR). However, the problem of key abuse consists in the CP-ABE system. The semi-trusted authority or the authorized user to access the system may disclose the key because of personal interests, resulting in illegal users accessing the system. Consequently, aiming at two kinds of existing key abuse problems: (1) semi-trusted authority redistributes keys to unauthorized users, (2) authorized users disclose keys to unauthorized users, we put forward a CP-ABE scheme that has authority accountability, user traceability and supports arbitrary monotonous access structures. Specifically, we employ an auditor to make a fair ruling on the malicious behavior of users. Besides, to solve the problem of user leaving from the system, we use an indirect revocation method based on trust tree to implement user revocation. Compared with other existing schemes, we found that our solution achieved user revocation at an acceptable time cost. In addition, our scheme is proved to be fully secure in the standard model.

This study presents an experimental work in a petrochemical company for scanning a buried pipeline using $Tc^{99m}$ radiotracer based on the measured velocity changes, in order to determine the flow reduction along a pipeline. In this work, $Tc^{99m}$ radiotracer was injected into the pipeline and monitored by sodium iodide scintillation detectors located at several positions along the pipeline. The flow velocity has been calculated between every two consecutive detectors along the pipeline. Practically, six experiments have been carried out using two different data acquisition systems, each of them being connected to four detectors. During the fifth experiment, a bypass was discovered between the scanned pipeline and another buried parallel pipeline connected after the injection point. The results indicate that the bypass had a bad effect on the volumetric flow rate in the scanned pipeline.

The objectives of this study were to research the power structure of the conjugal decision making process between husbands and wives and how to go about analyzing these processes. Furthermore, to statistically survey the similarities the differences of these between the Japanese and Korean cultures. The subjects of the study were women over the age of 20. The Korean wives resided in Taegu, the Japanese wives in Kobe. The questionnaire destributed to these subjects was bi-lingual in both Korean and Japanese. The data results are as follows : The frequency of negotiation was highest when the wife conceived an idealistic balance in the magnitude of authority arld control between she and her husband. On average, those wives who make decisions their husbands through negotiation do not have as high of a magnitude of control and authority as their husbands. These women idealistically believe that a balance of magnitude and authority exists between them and their husbands. On the other hand, in relationships where decisions are made without negotiation, the magnitude of the wife's authority increases as she idealistically perceives herself as being more powerful than her husband.
