우리나라 국가서지는 1963년에 제정된 도서관법에 따라 국립중앙도서관에서 매년 발행하여 공개하고 있다. 국가서지의 지속적 발전과 서비스의 혁신을 도모하고 있는 세계 각국의 움직임과 달리, 우리나라 국가서지는 그동안 거의 방치되다시피했던 서비스의 노후화 및 데이터의 구조적인 문제로 인해 사실상 거의 이용되지 않고 있다. 그럼에도 불구하고 국가서지는 한 국가에서 발행된 출판물에 대한 총체적 기록으로써 자국의 지식문화와 역사를 반영하는 상징이라는 큰 의미를 가진다. 본 연구는 우리나라 국가서지의 발전적 운영 방안을 제안하는데 목적을 가지고 있다. 이를 위해 (1) 국가서지에 관한 국제적 권고를 검토하고, (2) 현 시점에서 국가서지 서비스를 지속해야 하는 당위성을 검토한 다음, (3) 국가서지의 품질과 서비스 제고를 위한 세부 운영전략을 제안하였다. 세부 운영전략을 제안하기 위해 (1) 국가서지의 수록범위, (2) 데이터의 구축 방식, (3) 국가서지 서비스로 구분하여 현황과 문제점을 분석하였으며, 이에 근거하여 전략적 방향을 도출하였다. 논의에 필요한 데이터는 사례조사와 실무진 면담, 각종 문헌연구를 통해 수집하여 활용하였다.

Stress concentration mainly occurs near holes and notches. Then local stress is larger than nominal stress. It is necessary that stress concentration phenomena are studied because it can act as a cause of fracture of material. In order to analyze fracture of material including holes, stress concentration factor and stress distribution must be studied more carefully. In this paper the stress concentration and distribution of a slotted plate is examined. Hardened 7:3 brass plate with 4 different slots including a circular hole is used. And ratios of slot length to its root radius are 1, 2, 3, 24, 4. The stress distribution is measured by using strain gages attached to the plate with variable width. And obtained experimental data are adjusted by using calibrated gage factor.

People can differently act online than in real-life. Their virtual identities may allow them to express themselves more freely. In this perspective, there is a self-discrepancy between virtual- and real-life. Due to the anonymity, people can feel free to express who actually they are online without considering social pressure. Especially, for those people who live in a repressed society, virtual-selves can play a significant role to achieve their well-being. For this reason, a self-discrepancy between actual- and virtual-self related to well-being was studied. With 183 survey responses, political freedom, extraversion and neuroticism are identified as significant influencers of subjective well-being (SWB). In addition, an increase in self-discrepancy between virtual- and real-life for 'unhappy' people leads to an increased online well-being, which is contradictory to Higgins' self-discrepancy theory.

The Korean nationwide differential global positioning system (NDGPS) reference station transmits a global positioning system (GPS) enhancement signal using minimum shift keying modulation with a 200 bps data rate. The ocean-based DGPS covers the service area of 100 NM with 300 W output power; on the other hand, the land-based DGPS transmits the output power of 500 W, which covers the service area of 100 km. The DGPS reference stations with high output power can radiate spurious signals, which may act as interference sources affecting the other DGPS reference stations or the wireless ground stations that utilize the medium frequency band. In this paper, the radiation spectrums of the DGPS reference stations are measured and analyzed in the spurious domain. The DGPS radiation spectrums are evaluated from the perspective of the interference effect.

Objectives: This study explored the perception and practice of privacy protection of some dental hygiene students. Methods: On the basis of survey data from 126 respondents, the correlation between the perception and the practice was analyzed. Also the multiple regression analysis was performed on the variables that affect the practice. Cronbach's ${\alpha}$ of the questionnaire was more than 0.6. The items were scored on 5 points scale or true-false type. Results: The perception of privacy protection was 3.23 points, the law is 0.88 points, and the practice is 3.47 points. The educated students were more perceive than those who did not(p<0.05). The higher the perception, the higher the practice(r=0.230, p<0.01). The practice was influenced by the perception(p<0.05). Conclusions: Dental hygiene students should be educated to perceive and protect the personal and medical information of a patient. Also, an educational institutions need a efforts to protect personal information.

The effects of longitudinal heat conduction on the performance of heat transfer surfaces are investigated by using a single-blow method. In the transient testing method for determining the heat transfer characteristics, exponential inlet temperature variations are made by using screen-mesh heater with small time constant and low frontal velocities of the test section, and the experimentally determined inlet temperature profile is used as the inlet fluid temperature condition. The effects of longitudinal heat conduction are negligible only if $\gamma^\act<0.05\;and \;N_{tu}\le3$ and should be considered if $N_{tu}\le3$ The test results ate compared with the existing theoretical and experimental data and the validity of this technique is confirmed by the good agreement.

The successful implementation of green supply chain management(GSCM) practices requires a level of cooperation that can be difficult to conduct. Despite this challenge, limited scholarly attention has been paid to exploring how the implementation of GSCM practices can be effectively facilitated and enhanced through accumulated social capital with suppliers. Based on social capital theory, this study postulates that supplier network characteristics derived from social capital with key suppliers can be critical antecedents of GSCM, which in turn enhances the firm's environmental performance. To test hypotheses, data were collected from 330 firms in 15 countries, and structural equation modeling was employed. Results show that GSCM improves environmental performance, and structural and cognitive social capitals of the supplier network act as antecedents and lead to GSCM implementation.

This pilot study was performed to produce data of the Children's Dietary Life Safety (CDLS) Index which is required by the Special Act on Safety Management of Children's Dietary Life and to evaluate the CDLS Index for 7 metropolitan cities and 9 provinces in Korea. To calculate the CDLS Index score, data regarding the evaluation indicators in the children's food safety domain and children's nutrition safety domain were collected from the local governments in 2009. For data regarding the indicators in the children's perception & practice domain, a survey was conducted on 2,400 5th grade children selected by stratified sampling in 16 local areas. Relative scores of indicators in each domain were calculated using the data provided by local governments and the survey, the weights are applied on relative scores, and then the CDLS Index scores of local governments were produced by adding scores of the 3 domains. The national average scores of the food safety domain, the nutrition safety domain and the perception and practice domain were 23.74 (14.67-26.50 on a 40-point scale), 16.65 (12.25-19.60 on a 40-point scale), and 14.88 (14.16-15.30 on a 20-point scale), respectively. The national average score of the CDLS Index which was produced by adding the scores of the three domains was 55.27 ranging 46.44-58.94 among local governments. The CDLS Index scores produced in this study may provide the motivation for comparing relative accomplishment and for actively achieving the goals through establishment of the target value by local governments. Also, it can be used as useful data for the establishment and improvement of children's dietary life safety policy at the national level.

오늘날까지 정보주체의 개인정보들은 많은 기업이나 기관에 중앙 집중화되어 있는 구조였다. 하지만, 최근에는 점차적으로 정보주체가 자신의 개인정보를 통제하고 소유권을 찾는 방향으로 패러다임이 변화하고 있다. 해외는 일찍부터 EU의 일반 개인정보보호법(General Data Protection Regulation)이나 미국의 소비자 프라이버시 권리장전(California Consumer Privacy Act) 등으로 개인의 데이터 소유권을 강화하고 있다. 국내도 여러 기업들이 모인 연합체들에 의해 분산 ID 서비스 모델에 대한 기술 연구와 서비스 적용 사례들을 만들어 가고 있다. 본 논문에서는 현재 연구되고 있는 분산 ID 서비스 모델과 그 한계점에 대해 알아보고 해결할 수 있는 보다 개선된 분산 ID 서비스 모델을 제안하고자 한다. 제안 모델은 분산 ID를 제3의 기관인 보관자에게 안전하게 수탁하는 기능과 서로 다른 분산 ID 서비스가 생기더라도 상호 연동될 수 있는 연계 기능을 가진다. 아울러, 제안 모델의 보안 위협을 식별하고 보안 요구사항을 도출하여 보다 안전하고 편리한 모델을 제시한다. 분산 ID 기술은 사람에 대한 증명뿐아니라 향후 사물인터넷의 디바이스 ID 인증 관리에도 확장되어 적용될 것으로 기대된다.

Landscape zones have been designated as aesthetic old town districts across a wide range of Nakakyo-Ku and Shimokyo-Ku, city center of Kyoto, Japan. In these districts in which traditional structures and new buildings coexist, regulations of restriction on acts such as new building's heights, shapes, materials, and colors are carried out according to local governmental landscape ordinance based on Scenic Conservation Act. And yet, minimal fulfillment of the regulations according to different designer's subjective interpretation and principle of economy is rather creating abnormal shapes not harmonized with the traditional landscape. Thus, this study aims to extract combinations between form elements of middle and high rise apartment facade that affects 'harmony' and 'mismatch' in the districts by clarifying the social rules commonly implied based on intuitive judgments (sensibility evaluation) in which human experiential knowledge is involved. As research methods, the study first analyzes the form elements of the facade through a field survey, sets up a standard model through tasks of classification and segmentation and draws computer graphic images with 99 different patterns based on it. Based on these images, this study carries out sensibility evaluation and analyzes experimental data applying the rough set theory. As a result of the analysis, the combinations of form elements that affect harmony or mismatch act greatly when the colors and shapes of the pillars, positions and the patterns of the use of the first floor are combined.
