This study is the stone relics of the SukSusa temple site. Located in Young-ju, Kyungsangbuk Province, the Suksusa temple site is not well-known as the Silla Period Temple because of the Sosu-Seowon was built on the site and few historical records on the temple. Examination results of the stone relics, Suksusa temple was founded in the 7th century and was reestablished in the 9th century. Especially the shape and patterns of the stone Danggan prop and pedestals of Buddha Figures are similar to them of Birosa temple and Buseoksa temple that were sponsored mainly by royal family in the 9th century. Since ancient times, Sun-Heung province is very important place that was a cultural hub of transportation passage. In Sun-Heung province, the influences of the Hwaeom-jong around Buseoksa temple seems to have stimulated the growth of Buddhist arts in the 9th century. Also Suksusa temple was reflected on belong to the same buddhist culture such as relics. Its style of stone relics will be explained within the category of other stone relics in Sun-Heung province overall relics in same century. In addition to stone relics through the architectural member, also Suksusa temple was sponsored mainly by royal family in the 9th century. Therefore it is considered that Suksusa temple is high status which representative of the Unified Silla Period.

The purpose of this study was to identify population subgroups with similar patterns of diet quality, physical activity, alcohol consumption and cigarette smoking of Korean. The cluster analysis was conducted using the data from Korea National Health Survey(KNHS) in 1995, which consisted of 5,805 persons. We identified six health behavior typologies : 32.9% of the sample had a good diet but sedentary activity level(good diet lifestyle), 7.2% had high activity level but less diet quality(fitness lifestyle). Individuals in the passive lifestyle cluster(39.1%) had no active health promoting activities but tended to avoid risk taking health behavior such as cigarette smoking and alcohol drinking. 1.1% of the sample were in a drinking cluster, 17.2% in a smoking cluster and 2.5% had a hedonic lifestyle characterized by heavy drinking and smoking. The other characteristics of these lifestyle clusters could be presented by demographic and socioeconomic factors.

이순영,이경호,노홍석,정태성,김신,Lee, Soon-Young,Lee, Kyung-Ho,Noh, Hong-Seok,Jeong, Tae-Sung,Kim, Shin 대한소아치과학회 2011 大韓小兒齒科學會誌 Vol.38 No.4

침식 법랑질의 표층은 건전 법랑질과는 물리화학적 성상이 다르므로 침식 법랑질면에 대한 복합레진의 결합력을 증가시키기 위한 대안으로, 법랑질 내층으로의 침투력이 탁월한 infiltrant resin을 응용하는 방법을 생각하게 되었다. 본 연구는 다양한 정도로 인공 침식이 유발된 법랑질면을 대상으로, infiltrant resin과/또는 기존의 접착제를 적용한 경우의 복합레진 결합강도를 비교 분석할 목적으로 시도되었다. 건전한 순면을 가진 발거된 상악 유전치를 대상으로, 인공침식 유발 횟수 및 infiltrant resin과/또는 기존의 접착제를 적용한 방법에 따라 각 20개씩의 시료를 제작하였으며, 각 군의 미세인장 결합강도를 측정하고, 파절면의 파절 양상을 평가하여 다음과 같은 결과를 얻었다. 법랑질 표면의 침식 유발 횟수가 늘어날수록 결합강도가 낮았다(p<0.05). 기존의 접착제 상부에 infiltrant resin을 추가 적용한 군, infiltrant resin만 적용한 군, 접착제만 적용한 군의 순으로 미세인장결합강도가 높게 나타났다(p<0.05). 파절 양상의 관찰에서는 인공 침식 유발 횟수가 적은 군 및 infiltrant resin을 적용한 군에서 응집파절의 비율이 높게 나타났다. 결론적으로, 법랑질의 침식도가 클수록 복합레진 수복물과의 결합 강도는 감소하였으며, infiltrant resin으로 기존의 적찹제를 대체하거나 첨가함으로써 결합강도를 보완시킬 수 있을 것으로 판단되었다. Composite resin has been widely used for eroded enamel. But, as there have been many reports about the differences in physicochemical characteristics of eroded enamel compared with sound enamel, an additional effort was thought necessary to obtain the optimal bond strength. As a possible answer, we came to think about the application of infiltrant resin which is known to have an excellent penetration capacity into enamel. This study was performed for the purpose of comparing the bond strength of composite restoration with or without infiltrant resin under adhesives on the artificially eroded enamel. 60 extracted sound maxillary primary incisors were selected and divided into group 1, 2, 3 according to the number of artificial erosion cycling for 5 minute duration in 1% citric acid of pH 3.2 at $37^{\circ}C$. And the labial surfaces were divided into 3 areas; group A, only resin adhesive was used, group I, only infiltrant resin, group IA, infiltrant resin followed by resin adhesive. Afterwards, every specimen was restored with composite resin. Microtensile bond strength was measured and failure modes were observed. The obtained results were as follows: 1. In comparing the bond strength by the degree of enamel erosion, it was revealed the highest bond strength in group 1, followed by group 2 and 3, showing the lowest bond strength in most eroded group(p<0.05). 2. In comparing the bond strength by surface treatment methods, group IA and I showed higher value than group A(p<0.05), with unsignificant difference between group I and IA(p>0.05). 3. In observation of failure mode, it was shown higher frequency of cohesive failure in order of 1-2-3 and IA-I-A. Conclusively, it was shown decreasing tendency of bond strength as the enamel is more eroded, and infiltrant resin was thought helpful to replace or add to the resin adhesive for optimal bonding with eroded enamel.

The purpose of this study is to find the tracking of blood pressure in primary school-age children. A follow-up study was conducted from 1986 to 1990 on 330 first grade children attending primary schools in Kangwha County, Kyungki-Do. Basically we employed a linear regression model with random coefficients to figure out the relation between blood pressure changes and initial blood pressure. We obtained the following results ; 1. The mean blood pressures were increased grade went up in both sexs and were generally higher in female than male except for the systolic blood pressure at first grade. The size of difference was about 0.8 mmHg in mean systolic blood pressure and 1.5 mmHg in mean diastolic blood pressure. 2. The average annual increasing rates of systolic blood pressure were 2.5 mmHg in male and 3.1 mmHg in female respectively. For the diastolic blood pressure IV the average annual increasing rates were observed to be 3.0 mmHg in male and 2.9 mmHg in female respectively. Increasing rate of systolic blood pressure was significantly higher in female than male. 3. The adjusted regression coefficient of systolic blood pressure change on initial value was -0.11 in male and -0.13 in female and that coefficient of diastolic blood pressure change on initial value was -0.01 in male and -0.11 in female. This result shows that children with higher initial blood pressure do not pick up their blood pressure faster than others with lower initial blood pressure. There is no evidence of tracking of blood pressure in children. It is essential to find the earliest age having the tracking of blood pressure and we leave it for the further study.

The purpose of this study was to determine the relationships among the health concern, health practice and health status of Koreans. This study utilized the data from Korean National Health Survey (KNHS) in 1992. The data consisted of random sample of 2,799 individuals (1,304 male and 1,495 females) whose ages were between 20 and 59. The data were analyzed using SAS version 6.04 and LISREL version 7.13. The analytic methods for the study were chi-square analysis and covariance structural analysis. The results of the study were as follows. (1) There were significant positive relationships between health concern level and health practice index, and between health practice index and self-perceived health status. (2) There were negative relationships between practice index and chronic illness, and between health practice index and acute illness only in female. (3) Based on the findings, the structural model of the health concern, health practice, health status and socioeconomic variables was established and then the covariance structural analysis was used. The higher educational level and economic status were, the higher the health concern was. And urban residents were much more concerned with their health than rural residents. The more persons were concerned with health, the more they did health practices. And the more the health practice was, the higher the health status was. The younger the persons were and the higher the health status of one's family was, the higher the health status was. In female, the higher the economic status was, the higher the health status was.

이순영,Lee, Soon-Young 대한예방의학회 1996 Journal of Preventive Medicine and Public Health Vol.29 No.2

Exploring the epidemiological trend of HIV/AIDS is required for making the national AIDS policy. In this study, the trend of HIV/AIDS incidence, rout of transmission and some characteristics of AIDS for the past 11 years in Korea using the reported cases from the national STD screening scheme were reviewed. Based on the results, the trend of main route of transmission according to the year was established by stage and the HIV/AIDS cases in this year was estimated and that to the year 2000 was projected by 'Epimodel' programme. The results were as follows : 1. Of the total infected persons, 76% were in their twenties and thirties, socioeconomically and sexually active age groups. While the transmission by sexual contact overseas was decreasing, the infection through domestic heterosexual and homosexual contact was increasing. 2. In the middle of the 1980's, the infected persons were mainly prostitutes infected through heterosexual contact with the HIV positive foreigner in this county(stage 1). And in the late of the 1980's the main source of infection was the sexual contact overseas and the domestic heterosexual contact(stage 2). Since the early of the 1990's, the infection through the heterosexual contact with non-regular sexual partner in this country has increased rapidly(stage 3), which was the evidence of the possibility of HIV epidemics. After that, it was expected that the infection through the homosexual contacts, the heterosexual contacts with commercial sex workers outside and the non-regular sexual contact inside of this country would increase continuously. In the result, the occurrence of neonatal infection by vertical transmission was expected(stage4). 3. The number of HIV/AIDS was estimated at 572 to 2,313 and the projected number of HIV/AIDS to the you 2000 was around 5,800 including 627 AIDS patients. For the further study on the estimation and projection of HIV/AIDS, it was suggested that the sampling survey on the HIV infection rate in the high risk groups and the sentinel hospital surveillance system should be conducted.

이순영,Lee, Soon-Young 한국전기전자학회 2009 전기전자학회논문지 Vol.13 No.1

시간지연 시스템 제어에서 시스템 모델과 외란에 대한 정보를 정확히 구할 수 있으면 스미스 예측제어기를 이용하여 이상적인 출력 특성을 얻을 수 있다. 따라서 본 논문에서는 모델링 오차 및 외란이 존재하는 시간지연 시스템을 효과적으로 제어할 수 있는 적응제어 알고리즘을 제시하였다. 이를 위하여 시스템 모델과 외란을 검출 할 수 있는 적응관측자 및 적응 알고리즘을 제안하였으며 이 신호들을 이용한 스미스 예측제어기를 구성하였다. 그 결과 모델링 오차 및 외란의 영향을 소거할 수 있는 제어기를 설계 할 수 있었다. 이렇게 구성된 제어기에 대하여 컴퓨터 시뮬레이션을 행하여 제안된 시스템의 효용성 및 우수성을 입증하였다. In control of time delay systems, if the informations about the system model and the disturbance can be estimated exactly, the ideal response can be achieved by using Smith predictor controller. Therefore, in this paper, an adaptive algorithm is proposed to control time delay systems existing modelling errors and disturbance. An adaptive observer to estimate disturbance and system model is designed and adaptive laws adjusting the observer are proposed. The new Smith predictor controller is designed using the proposed adaptive observer. As a result, the proposed controller can eliminate the effects of the disturbance and the modelling error. The effectiveness and the improved performance of the proposed system are verified by computer simulation.

This study analyzed the previous studies and utilization cases on library big data, and based on this, analyzed the collection/circulation data of the library big data platform and tried to derive meaningful analysis results. And five analysis indicators were selected: the increase rate of collections by annual, the composition of collections by subject, the composition of unborrowed collections by subject, the rate of borrowed collections, and use factor by subject. The analysis data is 6,722,603 cases of collection/circulation data from 33 public libraries in Busan. The main analysis results are as follows. First, it was found that the gap in the number of circulation was larger than the number of collection in the 33 public libraries. Second, the annual increase rate of collections also showed a clear decline. Third, each library showed a similar pattern in the composition of both the collections and the unborrowed collections by subject. Fourth, it was found that users' circulation were very different by subject and library. Fifth, in most libraries, the rate of circulation of collections and use factor in the natural science field were the highest.
