Objective : Hyperlipidemia and hypertension are well recognized risk factors of cerebrovascular disease. So it's very important to evaluate blood pressure and s-cholesterol in adolescence. Material and Methods : April 1999, we were requested health examinaion for high school students of a boys high school and a girls high school in Jeonbuk, Korea. The subjects were 360 students, boys were 317 and girls were 343. They were checked their height, body weight, blood pressure, and s-cholesterol. Results and Conclusion : The mean of systolic blood pressure of study subjects was $111.89{\pm}12.43mmHg$. In boys, it was $116.25{\pm}11.78mmHg$, and in girls, it was $107.87{\pm}11.64mmHg$. The mean of diastolic blood pressure of study subjects was $68.45{\pm}9.40mmHg$. In boys, it was $66.92{\pm}10.00mmHg$, and in girls it was $69.85{\pm}9.40mmHg$. Hypertensives were 18(5.68%) in boys, 10(2.92%) in girls. The mean of s-cholesterol of study subjects was $174.95{\pm}32.28mg/dL$. In boys, it was $178.91{\pm}34.51mg/dL$, and in girls, it was $171.29{\pm}29.66mg/dL$. Hypercholesterolemias were 91(28.71%) in boys, 39(11.37%) in girls. The mean of BMI of study subjects was $21.12{\pm}3.27kg/m2$. In boys, it was $21.05{\pm}3.26kg/m2$, and in girls, it was $21.18{\pm}3.29kg/m2$. Obese boys were 18(5.68%), obese girls were 13(3.79%). The mean of diastolic blood pressure in obese boys was significantly higher than that of normal boys(p=0.001, Mann-Whitney test). The mean of s-cholesterol in obese boys($BMI{\ge}274$) was significantly higher than that of normal boys.(P=0.26, Mann-Whitney test).

실체뷰는 질의 처리의 성능 향상을 위한 수단으로 널리 연구되어 왔다. 실체뷰는 하부 데이타가 변경되었을 경우 일관성을 유지해야 하는데, 그 기법으로는 뷰를 하부 데이타로부터 재생성하는 방법과 변경 내용 중 뷰와 관련 있는 것만 반영하는 점진적 갱신이 있다. 최근 XML이 웹 데이타 교환의 표준으로 대두되면서 XML 문서를 효율적으로 저장하고 검색하는 기법에 관한 연구가 활발히 수행되고 있다. 본 논문은 XML 문서를 기존의 관계 DBMS에 저장할 경우, 자주 제기되는 질의의 결과를 XML 실체뷰로 지원하고 그것을 점진적으로 갱신하는 기법의 성능 평가에 관한 것이다. XML 실체뷰 및 그것의 점진적 갱신을 지원하는 XML 저장 시스템의 구현에 대해 기술하고, XML 실체뷰의 점진적 갱신 기법의 성능을 실험을 통해 평가하였다. 실험 결과, 자주 제기되는 질의에 대해 매번 그 결과를 재생성하는 것보다 그 결과를 실체뷰로 유지하면서 뷰의 하부 데이타에 대한 변경 중 뷰와 연관성이 있는 것만을 점진적으로 반영하여 일관성을 유지하는 실체뷰 기법이 XML 데이타의 검색에도 효율적이라는 것을 확인하였다. Materialized views have received much attention for query performance improvement. They need to be refreshed whenever their underlying data sources are updated. They could be recomputed from scratch or they could be incrementally refreshed by reflecting only those portions of updates that affect them. With emergence of XML as the standard for data exchange on the Web, active research is under way on effectively storing and retrieving XML documents. In this paper, we describe a performance study on the incremental refresh of XML materialized views for the case where XML documents are stored in a relational DBMS, and XML materialized views are maintained with incremental refresh. We describe implementation of a prototype XML storage system that supports XML materialized views and their incremental refresh, and report the performance results obtained with the implemented system through a detailed set of experiments on the incremental refresh of XML materialized views. The results show that the XML view maintenance with incremental refresh outperforms the ordinary view recomputation.

Duodenal cancer is a kind of rare disease and it's incidence is about 0.035% out of 500,000 autopsies (Kleinerman). Malignant lymphoma primarily originated in duodenum is reported more rarely and Allen Good reported only one case of 341 cases of small bowel rnalignancies. Recently, the authors diagnosed one case of primary duodenal lymphoma confirmed by gastrofi- broscopic biopsy, performed pancreaticoduodenectomy radically and postoperative course is relative- ly good. Chemotherapy (C.H.O.P) is given to him. So, we reported here with review of literatures.

Purpose: This study was conducted to investigate and compare the growth, blood pressure, and s-cholesterol of urban and rural students in Korea. Methods: April 1999, We examined the students' health of a boys high school and a girls high school in a urban area - Jeonju, Korea.(boys were 317, girls were 343). And we also examined the students' health of a high school in a rural area - Gimje, Korea.(boys were 33, girls wee 36). Height, body-weight, Body Mass Index(BMI)I, blood pressure, and s-cholesterole were checked and compared between two groups. Results and Conclusion: The mean of height in urban students was $165.25{\pm}7.79cm$, and that in rural students was $163.77{\pm}8.72cm$. There was no significant difference stastically between two groups. The mean of body-weight in urban students $(57.78{\pm}10.51kg)$ was significantly higher than that in rural students $(54.71{\pm}10.11kg)$)(p<0.05). The mean of body mass index(BMI) in urban students $(21.12{\pm}3.27kg/m2)$ was significantly higher than that in rural students $(20.30{\pm}2.69kg/m2)$(p<0.05). Obese students $(BMI{\geq}27)$ were 31(4.70%) in urban students, 3(4.35%) in rural students. The mean of systolic blood pressure in rural students $(114.99{\pm}9.50mmHg)$ was significantly higher than that in urban students $(111.89{\pm}12.42mmHg)$(p<0.05) The mean of diastolic blood pressure in rural students$(75.72{\pm}9.90mmHg)$ was very significantly higher than that of urban students $(68.45{\pm}9.40mmHg)$(p<0.001). Hypertensives (${\geq}138/86mmHg\;in\;boys,\;{\geq}130/83mmHg$ in girls) were 28(4.24%) in urban students, 13(18.84%) in rural students. The mean of s-cholesterol in urban students was $174.95{\pm}32.28mg/dL$, and that in rural students was $176.81{\pm}33.18mg/dL$. There was no significant difference stastically between two groups. Hypercholesterolemias (${\geq}198mg/dL$ in boys, ${\geq}212mg/dL$ in girls) were 130(19.70%) in urban students, 14(20.89%) in rural students. These results suggest that there are differences in body weight, BMI, and diastolic blood pressure between urban and rural students and that it is necessary to consider these differences in health examination.

도시리질리언스 관점에서 본 지방정부의 코로나19 정책진단 및 함의 - 부산광역시 사례를 중심으로 -

본 연구에서는 지방정부차원에서 코로나19와 같은 감염병 대응정책의 역할정립을 위해 현재 지방정부에서 추진 중인 코로나19 관련 정책을 도시리질리언스 관점에서 진단하여 이를 토대로 정책적 함의를 제시하였다. 이를 위해 도시리질리언스 관련 선행연구를 조사하여 연구의 분석 틀 근거로 활용하였다. 도시리질리언스 관점에서 진단한 결과는 다음과 같다. 첫째, 부산광역시는 대·내외적인 거버넌스 구축을 통해 다양한 조직을 운영하고 있지만, 실질적으로 시민이 추진주체가 되어 의사결정에 반영되는 체계가 부재하다는 점이다. 코로나19 팬데믹이라는 전례 없는 전국가적인 상황에서 시민의 참여는 제한될 수밖에 없지만 그럼에도 불구하고 시민이 참여할 수 있는 사업의 구체적인 내용은 제시되지 못하고 있다. 둘째, 현 시점에서 코로나19의 종식을 언제쯤 확신할 수 있는지, 종식을 위해 취할 방법이 사회적 거리두기와 같은 방역정책인지 아니면 백신예방접종을 통한 집단면역인지에 대해서도 아직 명확한 대안이 없는 상황이다. 다만 명확한 것은 방역과 집단면역이 단계별로 같이 이루어져야 장기적으로 종식을 선언할 가능성이 높다는 점이다. 이러한 관점에서 부산광역시가 추진 중인 코로나19 대응 정책은 사실상 단기적 리질리언스, 즉 ‘회복력’에 중점을 두고 있다고 할 수 있다. 마지막으로 코로나 19의 확산세가 여전히 꺾이지 않고 있는 현 시점에서 리질리언스 차원의 부산광역시만의 코로나19 대응과 관련된 기본구상 정립이 필요하다. 이에 따라 현재 추진 중인 정책 및 다양한 특화 사례를 검토하여 종합적인 계획수립을 통해 장기적인 리질리언스 차원의 정책으로 확장해 나아갈 수 있다. In this study, in order to establish the role of policies to respond to infectious diseases such as Corona 19 at the local government level, policies related to Corona 19 currently being promoted by local governments were diagnosed from the perspective of urban resilience, and policy implications were suggested. To this end, previous studies related to urban resilience were investigated and used as the basis for the analysis framework of the study. The results of the diagnosis from the perspective of urban resilience are as follows. First, In the unprecedented nationwide situation of the Corona 19 pandemic, citizens" participation is bound to be limited, but nonetheless, specific details of projects that citizens can participate in have not been presented. Second, From this point of view, it can be said that Busan Metropolitan City"s policy to respond to Corona 19 is in fact focusing on short-term resilience. Finally, at the present time when the spread of Corona 19 is still not declining, it is necessary to establish a basic concept related to the response to Corona 19 only in Busan at the level of resilience. Accordingly, it is necessary to expand the policy at the level of long-term resilience through comprehensive planning by reviewing current policies and various specialized cases.

N/A To investigate the distribution of hepatitis B surface antigen (HBsAg) in the Pohang city and its neighbourhood area, surveyed 1334 persons who visited hospital general health screening center for check up. The study was performed by RPHA (693 cases) and EIA method (641 cases) with sera obtained. 1) EIBsAg was detected in 108 persons with the positive rate of 8.1% 2) The positive rate among females (10.55%) was greater than that of males (6.22% ) (p<0.005). 3) The age distribution of occurrence rate was found between 20 and 79 years of age ancl the highest rate was 70 to 79 age group(p<0.01).
