정우식,권영빈 중앙대학교 정보통신연구소 2000 정보통신연구소논문집 Vol.2 No.2

본 논문에서는 원고지 상에 작성된 문자들의 교정을 위한 제스쳐 인식 방법을 제안하고 있다. 원고지의 교정용으로 제시된 13개의 정의된 제스쳐를 중심으로 흘려 쓴 원고의 내용을 수정할 수 있도록 하였다. 이때, 인식을 위하여 제시된 프리미티브로는 직선, 곡선 및 원을 사용하였으며 이들은 벡터 세크먼트들의 조합에 의한 결합과정에 따라 한글 오토마타에 의해 정의되도록 하였다. 제시된 방법의 인식율은 40명의 다른 필기자가 작성한 520개의 샘플에 대하여 92%를 나타내어 실용화가 가능함을 보여주고 있다. In this paper, a method on handwriting gesture recognition for the oriental manuscript paper form is proposed. The pre-defined 13 different kinds of gestures are introduced on the boxed type manuscript paper on which the cursive handwrithing characters are already written. To detect the pre-defined gestures, primitives of line,curve, and circle are defined from the pre-calculated vector segments and its calculation using line merging process and automata. The recognition ratio of the proposed method is obtained at 92% among 520 samples with 40 different writers.

Experiments were conducted to isolate and identify substances responsible for dormancy and seed germination of dehisced seeds of ginseng (Panax ginseng C. A. Meyer). Radish cotyledon expansion bioassay revealed that the seed extract did contain a considerable amount of cytokinin-like substances and these substances were apparently decreased during the low temperature storage. GA-like activities were also found in the extract and these activities increased during the low temperature storage of dehisced seeds. TLC analysis of the purified extract exhibited several bands with none of them identical to the tested cytokinins; zeatin, zeatin riboside, kinetin and benzyladenine. The band, corresponding to Rf 0.36 in the TLC plate, showed definite cytokinin activities even after the several steps of purification.

권우성,김준수,채진욱,이근미,정승필,문용 영남대학교 의과대학 2003 Yeungnam University Journal of Medicine Vol.20 No.1

정상체중을 가진 성인 남성에서 지방과다(adiposity)와 심혈관계 질환의 위험요인과의 관련성을 알아보고자 하였다. 2001년 1월 3일부터 12월 31일까지 영남대 학교의료원에서 종합검진을 받은 만 28∼69세 성인 남성 129명을 대상으로 연령, 신체계측, 혈압, 공복 혈당, 혈청 지질대사치와 체성분 검사를 실시하였다. 체질량지수(BMI)가 18.5∼23 kg/㎡(76명)인 정상체중군과 23∼25 kg/㎡(53명)인 과체중군으로 분류하고, 체비방률, 체지방량과 위험인자들(수축기혈압, 이완기혈압, 공복시 혈당, 중성지방, 저밀도지단백, 고밀도지단백)의 상관관계를 분석하고, 정상체중군을 지방과다에 따라 3군으로 나누고, 각 군과 과체중군에서 심혈과 질환의 위험인자를 평가하였다. 정상체중의 제1군을 기준으로 제2, 3군과 과체중군의 위험인자 존재에 대한 비차비(odds ratio)를 조사하였다. 정상체중군에서 지방과다 변수들(adiposity variables: 체지방량, 체지방률)과 수축기 및 이완기 혈압, 저밀도지단백, 중성지방에서 유의한 상관관계가 있었다. (P<0.01). 나이를 보정하고 난 뒤 제1군을 기준으로 제3군(체지방율: 3.7, 체지방양: 4.7)과 과체중군(체지방율: 6.6, 체지방양 11.5)에서 위험인자에 대해 더 높은 비차비를 가졌다. 지방이 많은 정상체중의 성인남성은 적은 지방을 가진 성인 남성보다 심혈관 질환에서 더 높은 유병 위험도를 가졌다. 지방 측정은 정상체중군에서 심혈관계 질환의 위험인자외에 추가적인 정보를 제공할 수 있었다. Background: Most of all studies about the relation between the health risk and obesity are based on the European and American data. The purpose of this study is to examine the relation between adiposity and factors for cardio vacular disease (CVD) in normal weight individuals. Materials and Methods: Normal weight subjects with a body mass index (BMI) between 18.5 and 23 kg/㎡(76 subjects) and overweight subjects with a BMI between 23 and 25 kg/㎡ (53 subjects) were retained for this study. Normal weight subjects were divided into three group of each adiposity variable, then three group and the overweight group were evaluated for the presence of CVD risk factors and analyze the correlation coefficients between adiposity variables and risk factors controlled for age in normal weight, overweight groups. Using logistic regression analysis, the odds ratio (OR) for the prevalence of risk factors for each group of adiposity variables and the overweight group was estimated relative to the first group in normal weight subjects. Results: Systolic BP, diastolic BP, LDL cholestrol, HDL cholesterol, triglycerides in normal weight subjects were significantly correlated with all adiposity variables (P<0.01). Third group (3.7 for %fat and 4.7 for fat mass) of adiposity variables in the normal weight group and the overweight group (6.6 for %fat and 11.5 for fat mass) tended to have higher ORs compared to first group for risk factor variables. Conclusion: Normal weight subjects with elevated adiposity had higher prevalence of risk factors than normal weights subjects with less adiposity. Measuring of adiposity added additional information of cardiovascular disease risk factors in normal weight subjects.

權宇生,姜忠吉,李政明 경희대학교 부설 식량자원개발연구소 1978 硏究論文集 Vol.1 No.-

The present experiment was conducted to investigate the effect of several growth regulators on the growth and branching habit of pinched and nonpinched tomato plants (Lycopersicum esculentum Mill cv. Daehyung-boksoo). The results are as follows. 1. Spray of NAA decreased the number and fresh weight of axillary shoots of intact seedlings without influencing the main shoot growth. 2. TIBA decreased apical dominance of intact seedlings with little or no influence on the whole plant growth. In the pinched plants, however, TIBA caused severe growth inhibition as well as the decrease in apical dominance. 3. SADH treatment caused growth inhibition and increased apical dominance. SADH may be used only to obtain compact seedlings prior to transplanting. 4. GA promoted early growth and increased plant fresh weight On the contrary, the apical dominance of GA-treated plants was decreased as compared to the control 5. Ethephon at 500 ppm caused severe chlorosis and leaf abscission. The ethephon effect persisted for about 2 weeks after spraying

The aim of this study is to find out appropriate solutions to various problems created by wrong applied assumption of population. And these solutions are to be applied to establishment of urban planning. Besides assuming the population of urban planning is the most important yardstick of deciding the size of future urban and physical environment. Therefore to develop the plan more efficiently, I suggest these as followings. First of all, the mathematical methods which is proper to the characteristics of urban must be applied and produced through the outlook based on analysis of natural population, such as birth, death, transference in the past. Secondly, the moving in population of society must be limited on the target year. Thirdly, the population division plan by regional groups must be proceeded. The last but not least, the examination and evaluation on population plan must be performed.

권태봉,이정선,우영국,이명헌,정철원,주진순 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.1

위암발증의 원인을 밝히기 위하여 설문조사를 통하여 강원도 화천군에 거주하는 주민들의 일반사항, 생활습관 및 영양섭취실태와, ELISA법으로 Helicobacter pylori 감염률을 조사하였다. 조사 대상자는 40∼69세까지의 지역주민 169명으로 남자 79명, 여자 90명이었으며 그 결과는 다음과 같다. 조사 대상자의 학력은 65.7%가 초등학교 이하였으며, 월수입은 60%가 50만원 이하였다. 대상자의 62.7%가 농업에 종사하였고 자녀수는 64.3%가 3∼5명이었으며 대상자의 34.5%가 흡연을 하고 있었고 68.4%가 음주를 한다고 대답하였다. 대상자의 전체 평균신장은 156.7㎝로 여자는 150.1㎝, 남자는 164.4㎝ 이었다. 평균체중은 61.1㎏으로 여자의 체중은 57㎏, 남자는 65.7㎏이었으며 BMI는 전체 평균 25.5%로 여자는 24.8%, 남자는 20.1%이었다. Helicobacter pylori의 감염률은 전체 조사대상자의 66.3%이었으며, 여자의 67.7%, 남자의 64.6%가 감염되었고 연령별로는 40대의 70%, 50대의 62.2%, 60대의 69.4%가 각각 감염된 것으로 나타났다. 일상 생활 요인에 따른 Helicobacter pylori의 감염률은 흡연의 정도가 심하고 학력이 낮으며 월수입이 낮을수록 높은 경향을 보였다. Helicobacter pylori의 감염여부에 따라 감염자와 비감염자의 영양섭취량을 조사해 본 결과 비감염자는 감염자와 비교해서 에너지, 총단백질, 동물성 단백질, 칼슘, 비타민 C 섭취량이 높은 경향을 보였으며 철분과 niacin의 섭취량은 낮은 경향을 보였다. To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status, we surveyed 169 persons, 90 females and 79 males, aged 40∼69 years from June 7 to June 14, 1997, in Whachon area, Kang-Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation, life-style and food intake on Helicobacter pylori infection. Helicobacter pylori status was evaluated using an enzyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 66.3% of total subjects, namely, 67.7% of female and 64.6% of male and its prevalence increased with smoking, low education level and low monthly income. Energy, total protein, calcium and vitamin C intakes in the negative Helicobacter pylori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the Helicobacter pylori negative group than in the positive group.
