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.

N,N-bis(2-salicylaldehyde)dipropylenetriamine(5-Hsaldipn), N,N-bis(5-bromosalicyl-aldehyde) dipropylenetriamine (5-Brsaldipn), N,N-bis(5-chlorosalicylaldehyde)dipropylene-triamine(5-Clsaldipn), N,N-bis(2-hydroxy-5-methoxybenzaldehyde)dipropylenetriamine(5-OCH₃saldipn) and N,N-bis (2-hydroxy-5-nitrobenzaldehyde)dipropylenetriamine (5-NO₂saldipn) were synthesized and characterized by elemental analysis, infrared spectrometry, NMR spectrometry and mass spectrometry. Their proton dissociation constants were determined in 70% dioxane/30% water solution by potentiometric. Stability constants of the complexes between these ligands and the metal ions such as Cu(Ⅱ), Ni(Ⅱ) and Zn(Ⅱ) were measured in dimethyl sulfoxide by a polarographic method. Stability constants for the ligands were in the order of 5-OCH₃> 5-H > 5-Br > 5-Cl > 5-NO₂saldipn. Enthalpy and entropy changes were obtained in negative values.

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.

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.

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.

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.

We extend the sue of the method of least square to develop a recursive algorithm for the design of adaptive transversal filters such that, given the least-square estimate of this vector of the filter at iteration n-1, we may compute the updated estimate of this vector at iteration n upon the arrival of new data. The RLS algorithm may be viewed as a special case of the Kalman filter. Indeed this special relationship between the RLS algorithm and the Kalman filter is considered. We begin the development of the RLS algorithm by reviewing some basic relations that pertain to the method of least squares. Then, by exploiting a relation in matrix algebra known as the matrix inversion lemma, we develop the RLS algorithm. An important feature of the RLS algorithm is that it utilizes information contained in the input data, extending back to the instant of time when the algorithm is initiated. The resulting rate of convergence is therefore typically an order of magnitude faster than the simple LMS algorithm. This improvement in performance, however, is achieved at the expensive of a large increase in computational complexity

This study was carried out to investigate the yield and storability of onions on top-dressing period. Top-dressing period was applied in February, March and March, April with liquid fertilizer and solid fertilizer of farmhouse practice during the onion growing season. The yields of onion in experimental station field and farmhouse field treated with conventional fertilization were 53.2 and 56.6MT, respectively. However, they were 58.2 and 60.8MT with application of liquid fertilizer in February August were lower with application of liquid fertilizer on February and March(15.8%, 28.9%, compared with application of solid fertilizer by farmhouse practice(23.%, 41.0%), and were 20.7% and 31.7% by treatment of liquid fertilizer on March and April. In conclusion, treatment of liquid fertilizer on February and March decreased the rotting rate.
