The purpose of this study was to investigate the body composition, biochemical parameters, and consumption of convenience foods according to β-3 adrenergic receptor polymorphism in university students. A survey was conducted on a total of 486 students - 189 males and 297 females. Based on a self-reporting method, questionnaires were administered for over 20 minutes, and β-3 adrenergic receptor and blood samples were also analyzed. The genotype frequencies of β- 3 adrenergic receptor polymorphism were Trp/Trp homozygote (73.0%) and Trp/Arg heterozygote (27.0%) in male students. For the female students, the distribution of genotypes was Trp/Trp (71.0%) and Trp/Arg (29.0%). There were no differences according to biochemical parameters (ALT, cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, and hemoglobin) or body composition. Males with TT genotype frequently ate Ramyon (2.40±0.52), Cup Ramyon (2.37±0.39), Kimchi (2.23±0.61), and frozen meat (2.00±0.44), whereas males with TA genotype ate Fries (frozen food) (1.90±0.79), Smoked meat (1.67±0.81), and Canned fruit (1.64±0.81). Females with TT genotype frequently ate Frozen fries (2.21±0.35), Kimbab (2.12±0.44), and Ramyon (1.85±0.40), whereas females with TA genotype frequently ate Kimchi (1.73±0.98), Fries (frozen food) (1.46±0.26), and Cup Ramyon (1.30±0.34). When questioned about satisfaction about body shape, 22.8 and 60.8% of those with TT genotype answered that they were ``satisfied`` or needed to ``lose weight``, respectively, whereas 18.0 and 63.9% of those with TA genotype answered that they were ``satisfied`` or needed to ``lose weight``, respectively. In conclusion, this study found no significant effects in terms of β-3 adrenergic receptor polymorphism, which suggests that health-promoting education needs to be developed so that university students appropriately recognize their bodies and control their weight in desirable ways. Therefore, it is necessary to educate individuals with TT genotype how to buy reasonable foods by understanding the interrelationship between convenience foods and health care and by checking the nutrition index labels on convenience foods. Thus, it is recommended that a health-promoting program be developed for the promotion of healthy lifestyles.

본 논문에서는 고속 근거리망에 구축된 분산 데이타베이스 시스템에서 분할된 두 릴레이션 사이의 결합 연산을 최적화하기 위한 효율적인 알고리즘을 제안한다. 제안된 알고리즘은 프래그먼트(fragment)결합 할당 방법을 사용하여 응답시간을 최소화한다. 프래그먼트결합 할당 문제와 평형된 그래프 분할 문제 사이의 유사성이 식별되었다. 두 문제가 모두 Np-hard 문제이므로 그래프 분할을 위해 잘 알려진 휴리스틱 알고리즘이 결합 할당을 위해 수정되어 응용되었다. 각 프래그먼트에 관한 의미정보와 복사본을 이용하여 불필요한 처리비용을 줄이고 병렬처리 능력을 향상시킨다. 모의실험 결과 제안된 알고리즘이 기존의 알고리즘들보다 좋은 성능을 보여주며 각 사이트의 부하도 평형됨이 밝혀졌다. We propose an efficient optimization algorithm for the joins between two fragmented relations in a distributed database system on a fast local network. The algorithm uses the fragment join assignment method to minimize the response time of a join. The similarities between the fragment join assignment problem and the balanced graph partitioning problem are identified. Since both problems are NP-hard, a well known heuristic algorithm for graph partitioning is modified to solve the fragment join assignment problem. Semantic information associated with each fragment and duplicate copies are used to eliminate unnecessary processing costs and to increase parallism. Simulation results show that the proposed algorithm outperforms the existing algorithms and that the loads of sites are balanced.

현재 개발 진행 중인 하이퍼큐브형 데이타베이스 컴퓨터인 COREDB의 질의 처리 부분에 관하여 기술하였다. DBMS의 병렬화에 따라 기존의 비 병렬 DBMS에서는 발생하지 않던 새로운 문제점들이 발생하게 된다. 즉, 실제 병렬 연산을 수행하는 각 노드 컴퓨터와 이들을 제어, 관리하는 큐브매니저의 역할과 상호 작용, 질의 수행시 병렬성을 증가시켜 효율적으로 처리하기 위한 기법, 또한 단위 연산의 병렬화등의 문제점이 제기된다. 본 논문에서는 COREDB의 여러 구성요소 중에서 효율적으로 처리를 위한 여러가지 설계상의 문제점을 알아보고 구현상의 기법에 대하여 논하였다. 특히, SQL질의를 관계형대수의 기본 연산으로 변환, 분해하기 위한 두 단계 접근 방법, 즉 본래 SQL의 모든 부질의(sub-query)를 표현할 수 있는 기본 부질의로 변환한 후 최종적으로 관계형대수 기본연산으로 분해하는 방법과 이 과정에서 추가될 수 있는 질의 최적화 기법에 관하여 기술하였다. 또한, 기본 연산의 병렬화 및 효율적인 수행 전략에 대하여 설명하기로 한다. 위와 같은 일련의 과정에서 사용되는 내부 표현으로 질의 그래프 구조(query graph structure)를 사용하였으며, 릴레이션의 튜폴들을 수평 분할하여 각 노드 컴퓨터들에 분산시킴로써 병렬 처리의 효과를 증대시켰다.

N/A Sarcomatoid carcinomas are rare neoplasms that have been described using various terms, pseudosarcoma, carcinosarcoma or spindle cell carcinoma. Sarcomatoid carcinomas are epithelial tumors with sarcomatoid components and characterized by the presence of cytokeratin in pleomorphic spindle cells. These tumors of gallbladder rarely have been reported predominantly in older women with associated gallstones and their prognosis was very poor. However, the clinical and histological data are very limited. We report a case of sarcomatoid carcinoma in gallbladder confirmed by light microscopy and immunohistochemistry.(Korean J Med 57:1048-1052, 1999)

N/A Objective : Annually, the prevalence of indigenous and imported malarial infections is steadily increasing since 1993 in Korea. In order to understand the current characteristics of malarial infections and to prevent, the present research reviewed twenty-seven cases between January and September 1998. Method : In this study, all the twenty-seven (twenty- six patients) cases were obtained from admitted patients between January and September 1998. We had performed routine blood chemical studies, peripheral blood thin and thick smear, physical examination and abdominal sonography. Any patient with a previous history of a narcotic drug injection or had blood transfusion was excluded. Results : Twenty cases (74.1%) were indigenous and seven (25.9%) were imported malaria. Yeonchon-Gun (nine cases) was the most prevalent area in the indigenous cases; Cambodia (three cases) were the most one in the imported cases. Peripheral blood thin smear revealed Plasmodium vivax in all (100%) indigenous malaria, while four cases (57.1%) were P. vivax and one (14.3%) was P. falciparum and two (28.6%) were mixed infections with P. vivax and P. falciparum in the imported cases. In a 3-month period between July and September, peak prevalence (80.4%) was observed. The negative conversion of peripheral blood smear was achieved much earlier in the indigenous (3.9±1.4day) than in the imported (5.7±1.9day) after the treatment but, was not statistically signifcant. Conclusion : Plasmodium ovale was the only unique causative species in the indigenous malaria. Also Yeonchon-Gun and Cheolwon-Gun had been the most important endemic areas as previous reports. One relapse case had been occurred in the imported malaria. On the basis of our data, more efforts for control of malaria should be necessary for eradication and prevention of indigenous and imported malarial infections in Korea.

N/A With increasing life expectance and improvement of the overall health of the elderly, the understanding of geriatric disease becomes an important aspect of medical services. In the elderly, the frequencies of hypertension, DM, & anemia are increased according to aging and renal function is decreased progressively. As screening test for cervical cancer Papanicolaou smear is recommended due to its cost-effective benefits in females. In age-adjusted elderly male and female study populations, authors investigated the alterations of the above diseases, hypercholesterolemia, liver disease, obesity, & proteinuria distributions. Methods : This study included 1,181 aged 40 years (600 males, 581 females) visitors between January 1, 1997 and December 31, 1997 in National Medical Center, Seoul, South Korea. Authors divided these populations into two large groups such as group A and B. Group A was composed of 40-59 years, group B 60 years and older. Group A and B were subdivided into 4 subgroups each other, such as A-1, A-2, A-3 and A-4, B-1, B-2, B-3 and B-4 by means of age-adjusted dividing scale. We used our inclusion criteria to define each disease. Results : Hypertension was the most common disease in males of group B, but obesity was in females. The age-adjusted frequencies of hypertension, anemia, obesity & proteinuria were increased according to aging in the elderly aged 60 years and older. Though hypercholesterolemia revealed non-specific distribution in each group, increased frequency was observed in females compared to males in group B. With increasing their age, abnormal findings of Papanicolaou smear were found in females of group B. Conclusions : As the frequencies of hypertension, anemia, obestiy, proteinuria & abnormal findings of Papanicolaou smear were increased in the elderly aged 60 years and older as increasing their age. Much more attentions and follow up plans for these disease should be needed in the elderly.
