A Hangul character, composed of consonants and vowels, has a very systematic structure. And it may be classified into 6 types according to the form of vowels and the existence of final-consonants. To reduce the complexity of classified character, this thesis adopts the approach of separating each alphabet of a character and identifying the separated alphabets independently. For separating alphabets, this thesis devised background-thinning technique and utilized positional information of typed vowels - vertical vowel and horizontal vowel - obtained in type-classification stage as well as a priori knowledge on branch positions of vowels. In a test case with the most frequently used 917 printed Hanguls, the suggested approach achieved 97.71% of alphabet separation rate. While it still has a room for improvement, the promise of our approach was demonstrated.

Personality traits come to be associated with a brand in a direct way by the people associated with the brand-such as the brand's user imagery, which is defined here as "the set of human characteristics associated with the typical user of a brand". In this research, the authors develops the relationship between self-image and brand personality. This research have focused on how the personality of a brand enables a consumer to express his or her own self, an ideal self, and specific dimensions of the self through the use of a brand.

In hierarchical pattern classification, the use of a decision tree is an important approach. In the design of tree, a clustering algorithm is needed to be applied at each terminal node of the tree. The performance of this algorithm is very important since it is employed many times in the design of decision trees. In this paper, we reviews clustering algorithms that miniminzing entropy, minimzing overlap between pattern class groups, and keeping balance between these groups are considered.

肝組織에서의 Glucagon의 Cholesterol合成 抑制機轉에 對한 硏究

李根培,車鐘希,朴悅,高光三 朝鮮大學校 附設 醫學硏究所 1983 The Medical Journal of Chosun University Vol.8 No.1

The inhibitory mechanism of glucagon on hepatic cholesterol biosynthesis in rat was studied by the measurement of incorporation of tritium from ^(3)H₂O into cholesterol, and intermediary metabolite of lipids. But the rate of cholesterol synthesis was not affected. The hepatic acetyl-CoA carboxylase activity and malonyl-CoA concentration were decreased to 25~35% of control value during the same period after glucagon injection. These data indicates that one site of action of glucagon in regulating fat biosynthesis is at the acetyl-CoA carboxylase reaction.

Although the Working Formulation is commonly used to classify NHL in Korea, it has been recognized as imperfect for primary extranodal lymphoma, expecially for patients with nasal, paranasal disease because of their histological characteristics. Angiocentric T/NK cell lymphoma remains rare clinical presentation in North America and Europe but is more common in Asia and Latin America. The optimal mode of treatment has also not been decided on, probably because of their rarity and limited understanding of its natural course. The aim of this study was to analyze our experience with 14 patients with angiocentric lymphoma seen at the Chungnam Natioanl University Hospital over the last 5 years. We reviewed the records of 14 patients who were treated at the Chungnam National University Hospital between January, 1996 and December, 2000. The angiocentric T/NK cell lymphoma accounted for about 8.2% of NHL. The median age was 52.5 (range 36-71) years. Sex ratio was equal. According to the Ann Arbor staging system, disease was classified as stage Ⅰin 3 patients, stage Ⅱ in 8 patients and stage Ⅳ in 3 patients. Systemic B symptoms were present in only four patients in only four patients. All patients has extranodal involvement. The most frequently involved extranodal sites were nasal cavity followed by paranasal sinuses and orpharynx. The most common presenting symptoms were nasal obstruction with purupent rhinorrhea followed by dysphagia. According to the International prognostic index (IPI), most patients was in low-risk group (11 patients). Nine patients responded completely. Seven patients were received combination chemotherapy and 2 patients had radiation therapy as a initial treatment. Five patients were relapsed. After a median follow-up of 660.5 days, the overall survival and disease-free survival rates at 3 years was 56.8% and 42.9% respectively. The median survival time was not yet reached. The median overall survival time was 1338.5 (range 1212-1564) days for non-relapsed and 733.4 (range 302-1008) days for relapsed patients. The median time from CR to relapse was 100.5 (range, 39-159) days. There were limitations to know enough about the characteristics of angiocentric T/NK cell lymphoma because of a small number of patients. In the future, multicenter trials will be neccesary to identify clinical characteristics, optimal treatment mordalities and their responses, and prognostic factors.

Transthyretin의 Glutathione 자동산화 촉진작용

박종근,정신,김재휴,김수한,강삼석,이제혁,안봉환 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.8

When reduced glutathione(GSH) was incubated at neutral pH and at 37°, its concentration decreased slowly with formation of oxidized glutathione(GSSG). Autooxidation of GSH was accelerated by Cu^(2+) and Hg^(2+), but not by other common mono-, di-, and tri-valent cations. Transthyretin was found to stimulate autooxidation of GSH in the presence or absence of Cu^(2+) and Hg^(2+). EDTA inhibited perfectly the autooxidation of GSH regardless of the presence of transthyretin. The stimulating activity of transthyretin was maximal at pH 7.0, declining progressively with increase or decrease of pH from 7.0. Sulfhydryl-blocking agents such as p-hydroxymercuribenzoic acid and Nethylmaleimide markedly inhibited the stimulating activity of transthyretin. Transthyretin stimulated autooxidation of other sulfhydryl compounds such as clithiothreitol and cysteine. However, it did not show a significant effect on autooxidation of sulfhydryl group of egg albumin and eye lens proteins. And transthyretin did not cause any oxidative change to thyroxine(T₄), 3, 5, 3Ltri iodo thyronine(T₃) and 3, 3: 5~triiodothpnine(rT₃) bound to it in the presence of GSH and Cu^(2+). The above results suggest that transthyretin may play a role in regulation of oxidized status of sulfhydryl groups in blood plasma and cerebrospinal fluid

본 연구는 집성 염색 무니목 개발을 위하여 사용 가능한 수종과 3종류의 염료를 사용하여 염색시간, 염색온도, 함수율 및 Flitch 제작에 대하여 연구한 결과는 다음과 같다. 실험에 사용한 4수종 중에서 선삭성이 불량한 은수원 사시나무를 제외한 3수종인 소나무와 이태리 포플러, 마티카가 사용 가능한 수종으로 밝혀졌다. Stain은 번지거나 얼룩이 지는 현상, Dylon은 침투 불균일로 부적당하였으나 Fine은 염색상태가 양호하였다. 염색시간은 5시간 이상 되어야 염색정도가 양호하였고, 염색온도는 90℃에서 가장 적당하였으며 생재와 기건재 및 포수재에 대한 영향은 큰 차이가 없었다. Flitch제작에 적당한 함수율은 9%이었다. This study was carried out to develop laminated dyeing wood, for which usable three sixties of trees and 3 kinds of dye stuffs were used to investigate dyeing time, dyeing temperature, moisture content and manufacture of flitch, the results were as follows: Out of four species of trees used in the experiment, it was found that three species, Pinus densiflora, Populus euramercana and Dyrea costulata were usable excluding Populus tomentiglandulosa whose cutting ability was bad. As to influence according to the kind of dye stuff, the Stain of low price could be used as a coloring agent but it was not proper as a dyeing agent due to spreading or staining phenomenon. As Dylon which was generally used to dye textile penetrated them uneven, dyeing only their surface, it was also found improper to be used. On the other hand, the dyed condition was good with Fine. The dyed condition was good when dyeing time was more than 5 hours and it was the most adequate when the temperature was at 90℃. There was no significant difference between their influence on green, dried and saturated wood.-In the manufacture of Flitch, the most appropriate moisture content was 9%.

鎭海灣에 出現하는 有毒鞭毛操類의 分類 II 下痢性 貝毒種-Dinophysis屬

文成基,李三根 慶星大學校 1991 論文集 Vol.12 No.3

The classification of Dinophysis, responsible for DSP(diarrheic shellfish poison)was investigated during the period from 1984 to 1990 in Chinhae Bay. Identification was carried out by light microscopy and scanning electron microscopy. We identified 4 species: Dinophysis acuminata, Dinophysis caudata, Dinophysis fortii, and Dinophysis rotundata, Among those Dinophysis acuminata and Dinophysis fortii were discovered as causative orgnisms of DSP
