Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

Objective : Serum uric acid has now been identified as a marker for a number of metabolic and hemodynamic abnormalities. The aim of this study is to evaluate risk factors which influence hyperuricemia in the citizens of Asan. Method : The study design was cross-sectional and research subjects were 1086 citizens of Asan. General characteristics, cigarette smoking, alcohol consumption, and past history were obtained by interview using a structural questionnaire. Also, we measured height, weight and blood pressure, and serum uric acid of the subjects. Results : The mean serum uric acid level was 5.27 ㎎/㎗ in men and 4.01 ㎎/㎗, in women, In the multiple logistic regression analysis, statically significant risk factors of hyperuhcemia were gender, body mass index, blood lead concentration, and serum creatinine. Conclusion : Our results suggest that gender, body mass index, blood lead concentration, and serum creatinine might be the most important risk factors of hyperurcemia. Education program as well as routine check-up for serum uric acid was highly recommended for the effective prevention of hyperuricemia.

In this paper, it is proposed to improve the robustness of the Fast Recursive Least Squares (FRLS) algorithms with the exponential weighting, which is an important class of algorithms for adaptive filtering. It is well known that the FRLS algorithm is numerically unstable with exponential weighting factor λ<1. However, introducing some gains into this algorithms, numerical errors can be reduced. A proper choice of the gains then leads to a numerically stable FRLS algorithm with a complexity of 8m mulitiplications and we shown it by computer simulations.

Objectives : Recently, there has been a growing enthusiasm in biological approach to personality ; the identification of genes responsible for particular personality traits. The aim of this study was to investigate the association between the 5-HT_(1Dβ) G861C polymorphism and personality traits. Methods : We recruited 218 normal subjects. The Korean version of the Temperament and Character Inventory (TCI) was used to assess personality traits. From blood samples taken from the subjects, DNA was isolated using standard techniques and the HT_(1Dβ) G861C polymorphism was genotyped by means of polymerase chain reaction and Homogeneous MassEXTEND method. We classified the subject into the GG, CG, and GG groups according to their genotypes. The differences in the temperament factors of the TCI between homozygote group (GG+CC genotype) and heterozygote group (CG genotype) weretested. Results : The heterozygote group had significantly lower Harm avoidance (HA) scores and higher Self-directedness scores(SD) than the homozygote group. Conclusion : In conclusion, we found some associations between the 5-HT_(1Dβ) G861C polymorphism and the personality dimension HA and SD in a normal population.

Background : Bleeding after endoscopic procedure of the stomach carries an increased risk of morbidity and mortality. In case of oozing hemorrhage, not in active hemorrhage, powdered sodium alginate may play a role in control of bleeding with convenience. Therefore, we evaluated the clinical effect and efficacy of sodium alginate powder in upper G-Ⅰ bleeding. Methods : Forty-five patients who had upper G-Ⅰ bleeding after endoscopic procedure were enrolled in this study. Twenty-five patients of them were managed by the application of powder preparation of Sodium alginate(ALTO). The others were observed without treatment. The next day, we performed endoscopy in all patients to ascertain the hemostasis. Results : Of 25 patients managed with Sodium alginate, only two patients(8%) had bleeding (hemostatic rate : 92%), On the other hand, of 20 patients who did not receive any treatment, 3 patient(15%) had bleeding (hemostatic rate : 85%). There was no statistical difference between the two groups(p>0.05). Using other endoscopic procedure, We successfully treated the patient who continued to bleed. Conclusion : We evaluated the effect of the spary of sodium alginate on oozing hemorrhage. Although there was no statistical significance in our study, it seems that the spray of sodium alginate may be a useful method for the prevention of bleeding after endoscopic procedure.

A low frequency square wave driven electronic ballast for metal halide (MH) lamps is developed. The lamp current/wattage is controlled by fuzzy logic controller based on the low cost 8-bit microcontroller. This electronic ballast consists of a buck converter, a low frequency square wave full bridge inverter, a high voltage burst pulse generator using IGBT for the MH lamp ignition, an over-current protection circuit and an 8-bit microcontroller circuit. The ballast system is operated on the constant current mode during the MH lamp start-up process and the system is operated on the constant power mode during steady state. Experimental results show that the fuzzy logic control operation is carried .out successfully by the 8-bit microcontroller PIC16F877. In this electronic ballast system, in spite of the limited control bandwidth caused by low operating speed of the %bit microcontroller, the good performance in the constant lamp current characteristic is obtained. Acoustic resonance of the MH lamps can be effectively avoided because the instantaneous lamp power is fully constant due to the low frequency square wave drive.

This study aims to review the research trends concerning apartments and multi-family housings. Apartments and multi-family housings are the big rates of residence in the cities including Seoul in Korea. Since 1970s, it had happened because of overpopulation, the lack of building sites and inflated land prices. It spreaded big cities to the suburbs, starting from the 21st century. The size and the types of housings are becoming more and more various and evolved. People need variegated and efficient places to live because their lifestyle have become complicated and diverse. The requisite for improving the quality of residential environment are not only using luxury materials or enlarging spaces, but also requesting psychological, and social economical satisfaction. It profound studies are demanded about the residence. The residential environment is an area that contains personal lifestyle and directly affects tenants' behavior and expectation. The scope of review is limited to the articles listed in the Journal, Korean Institute of Landscape Architecture and the Architectural Institute of Korea. This research ranges from 1985 to 2006 June, where the studies on apartments were seriously started.

By useing hisusik-makjingi(희수식맥진기) we analysed lung-pulse of common cold patient. The result as fellow ; 1. In case of wind-cold common cold patient, It is short-avove pulse type and when cold transfer to fever it is dry-cold type pulse. 2. In a case of wind-heat, there is a pulse of above-frequent or frequent-stringed. And also we can find out that in a mild fever case there is not a frequent pulse meaning the heat. 3. In case of vutal energy shortage and yabggi deficiency, we can also notice that the pulse is so powerless. 4. The patient who have had an old complaint and a serious illness didn't show the accordance with the pulse and common cold type.
