The incidence of double primary cancer is about 10% in all kinds of cancers. Double primary cancer is usually accompanied by gastrointestinal cancer. Esophageal cancer is supposed to be frequently accompanied by squamous cell carcinoma of the head and neck or the upper respiratory tract, because of such common carcinogens as smoking and alcohol ingestion. Esophageal cancer and hypopharyngeal cancer are usually diagnosed by esophagogastric endoscopy with biopsy. We performed endoscopic ultrasound-guided Trucut biopsy(EUS-TCB) to diagnose a mediastinal mass in a 49 year-old patient, who visited our hospital because of voice change. During procedure, we accidently found enlarged celiac lymph node, and obtained tissue from the mediastinal lymph node and the celiac lymph node. We confirmed double primary cancer of squamous cell carcinoma in the esophagus and the hypopharynx via esophagogastric endoscopy.

토양으로부터 CGTase와 CDase를 함께 분비·생산하는 내열성 세균을 분리하였으며, 동정결과 Bacillus stearothermophilus로 판명되어 KJ16으로 명명하였다. Bacillus stearothermophilus KJ16 균주는 회분배양할 경우 2단계 성장을 하며 일차증식기에 CGTase를 생산하고 이차증식기에 CDase를 생산하는 양상을 보였다. 배치 pH를 7.0으로 조절하면서 배양할 경우, CGTase는 균의 증식에 따라 증가하고 CDase는 CGTase보다 뒤에 생산되었다. 그 생산양은 pH 비조절 배양에 비해 CGTase는 최대 12배(1300 mU/ml)까지, CDase는 2배(225 mU/ml)정도 증가되었다. 분리균주가 생산하는 CGTase는 분자량이 65,000 dalton으로 pH 6.0, 60℃에서 최적활성을 보이며 HPLC 분석을 통해 α-, β-, γ-CD를 42: 46: 12의 비율로 생산하는 α/β 혼합형 CGTase였다. 또한 CDase는 분자량이 68,000 dalton으로 pH 6.0, 55℃에서 최적활성을 보이며 최적기질은 γ-CD였다. A bacterium named as Bacillus stearothermophilus KJ16. The growth of the isolated strain occurred in two steps, and syntheses of CGTase and CDase were dependent on the growth cycle of the cell. CGTase was constitutively synthesized during the 1st growing phase, while CDase was synthesized inducibly during the 2nd growing phase. When the medium pH was controlled at 7.0, the maximun enzyme activities of CGTase and CDase were increased by 12-fold(1300 mU/ml) and 2-fold (225 mU/ml), respectively, compared with the pH-uncontrolled batch culture. The CGTase of the isolate converted soluble starch to CDs with the ratio of α-CD: β-CD: γ-CD=42:46:12 at 55℃. The optimal pH and temperature of CGTase were 6.0 and 60℃, respectively and the optimal pH and temperature of CDase were 6.0 and 55℃. The molecular weights of the purified CGTase and CDase were estimated to be 65,000 and 68,000 dalton, respectively. Among serveral substrates, γ-CD was most rapidly hydrolyzed by the purified CDase.

부산에 소재한 3개 초등학교 청소년단체 소속의 초등하교 3학년부터 6학년까지 구성된 172명을 대상으로 청소년단체 지도자, 초등학교교사, 자원봉사자, 의사와 영양사가 1박 2일간의 해양스포츠 체험활동 을 통한 건강교실을 시행하였다. 대상자의 체질량지수, 체지방량을 측정하여 비만정도를 평가하였으며, 칼로리 섭취에 대한 강의를 시행하였고, 설문지 조사를 통해 대상자의 식이 섭취 습관에 대한 조사를 시행하였고, 본 건강교실에 대한 만족도를 측정하였다. 대상자중 남자에서는 40%, 여자에서는 25.69%에서 비만 경향을 보였다. 대상자의 대부분에서 시행된 건강교실에 긍정적 반응을 보였으며, 향후 체계적인 구성과 철저한 사전계획이 병행되어 본 증례 보고와 같은 건강교실을 시행한다면, 비만아동에서 거부감 없이 비만에 대한 교육을 실시할 수 있으며, 정상 체중 아동군에서도 비만에 대한 예방교육을 시행할 수 있는 프로그램이 될 것이다. 172 elementary school students involved this health program. This subjects were learened about obesity that affect health problem, ideal eating habits, calories that contained in the children's favorite foods by doctors and nutritionist. And this stubjects were checked heights, weight, body fat percent. Obesity is 40% in the boys and 25.69% in the girls. Most subjects were satisfactory with this health program. So we will effectively educate obese children without resistance and prevent normal weight children from obesity through structured and well-designed health program that similar to this program.

A bacterium producing Cyclodextrin Glucanotransferase (CGTase) and Cyclodextrinase (CDase) was isolated from soil, and named as Bacillus stearothermophilus KJ16 . The growth of the isolated strain occurred in two steps, and syntheses of CGTase and CDase were dependent on the growth cycle of the cell. CGTase was constitutively synthesized during the 1st growing phase. while CDase was synthesized inducibly during the 2nd growing phase.

This paper presents the future direction of the development and maintenance of the urban park of the Kumi city. The direction was obtained by analyzing the evaluation results on the satisfaction level of park use and the park image of the park users. The analysis results are as follows. 1) It turns out that the rest and accommodation facilities are the major facilities that uplifts the total image of the park. 2) Among the park images, the image on the pleasantness was the major image, related with the satisfaction on the park equipments. 3) The social class, who gave a bad score on the above equipments and images, is a low-aged class, who is a white class with high income as well. Therefore, it is suggested that the park maintenance plan, with emphasis on the class, is an important task.

Objectives : This study was conducted to estimate the comorbidity rate of ADHD in a group of patients with alcohol dependency and to find out the characteristics of alcoholic patients with ADHD using the diverse clinical and genetic variables. Methods : Eighty five patients with alcohol dependency were recruited from 4 mental hospitals in Kyoung-Nam and Kyoung-Ki province. For the evaluation of ADHD symptoms in both childhood and adulthood, the highly structured Diagnostic Interview Schedule for Children-IV (DISC-FV)-ADHD module was used. The various standardized scales and questionnaires were also applied to evaluate the comorbid conditions and psychopathological status. All the subjects' blood was collected and genetic study for the polymorphism of DRD2, TH, 5-HTTLPR, COMT, ALDH2 was performed. Results : 1) The comorbid rate of definite ADHD in alcoholic patients was 38% (28/85). 2) The frequency of unmarried status was significantly higher in ADHD group compared non-ADHD group. 3) The onset of pathologic drinking and auditory hallucination was significantly earlier in ADHD group than non-ADHD alcholic group. 4) In ADHD alcoholic group, antisocial behavior was more frequently reported, and the score of co-dependency scale, depression/anxiety, aggression and obsessive compulsive drinking scales were significantly higher compared to non-ADHD alcoholic group. 5) No signficant difference was found in the frequency of polymorphic alleles in COMT, DRD2, 5-HTTLPR, ALDH2, TH between ADHD and non-ADHD alcoholic group. Conclusion : In alcoholic patients, the rate of adult type ADHD was higher than expected rate in general population. The alcoholic patients with ADHD suffered from more sever degree of alcohol dependency and earlier alcohol related problems. ADHD-alcoholic group showed higher diverse comorbid psychopathology and lower marital status compared to non-ADHD-alcoholic group. No difference, however, was found in genetic data between two groups.

Purposes : To investigate the viral etiology of community-acquired pneumonia in Korean adults, we have detected respiratory viruses (Respiatory syncytial virus, adenovirus, influenza virus and parainfluenza virus) in the way of prospective, multi-center study. Methods : From July 1997 to April 2000, nasal aspirates or sputum were obtained from adults patients with community pneumonia admitted to the participating hospitals and transferred immediately to the central laboratory at the Seoul National University Children's Hospital. The specimens were divided into three parts. One part was used for indirect immunofluorescent test for respiratory viruses, the other part for the culture of RSV and adenovirus in HEp-2 cell monolayer. The other part was used for the culture of influenza virus and parainfluenza virus in MDCK or LLC-MK2 cell monolayers. Results : Of 317 samples, 32 (10.1%) specimens were positive for viral agent by indirect IF staining or culture, including one dual-infected specimen (adenovirus and parainfluenza virus). Influenza virus was most commonly detected (16 specimens). Parainfluenza virus, adenovirus and RSV were detected in 10, 4 and 3 patients, respectively. All isolated influenza viruses were type A (H3N2 in 9 patients, HIN1 in 2 and unspecified in 5), and 8 out of 10 parainfluenza virus isolates were type 3. Conclusion : Similar to previous reports from other countries, a significant portion of community-acquired pneumonia in Korean adult is caused by respiratory viruses.
