This study in to know the development transition of juveniles age(10∼17 of ages) about the relationship of natural developmental, patterns, according to sexes, ages and regions by vertical and crossing methods. To analyze the degree developed through intended training and its related meaning, the objects are chosen from 4 regions(urban, farming and mining community etc). The objects for vertical study are 2000 persons : crossing study, 6400 : experimental study, 320 The results through analyzing statistical date by electronic computer, based on the materials investigation, measurement and experiment, from July 1 to Nov. 30 1987, are following 1. The aspect of the form This report was represented that the body measurement value of the height, the weight, the chst-girth, and the sitting height was continuously increased the growth development till 10∼17 age, according to increased with age, and the cross-sectional change have a tendency both for male and female to excess crossing change. 2. The aspect of the function (in the viewpoint of action fitness element) 1) This report was showed that the fitness of the male continuously in creased till 17 ages, and that of the female in distinctly decreased or maintained after 14 ages. 2) The exercise items prevailed the crossing change were the speed (100M sprint), the power (throwing) and endurance of total body (longtime running (female)) And the exercise items prevailed the vertical change were the power (long jump), endurance (muscle endurance : chinning, chin hanging, sit-ups, endurance of total body : 800M and 1,000M lony-time running) 3. The results through experiments 1) Grip strength (1) Maximal strength The development of strength is almost parallel to the development of body and it shows rapid development speed, especially, in the adolescent juveniles. (2) Muscle Endurance There are outstanding development in both sexes. Because the development speed become slow after being 15 of ages, applying muscle endurance training from being 14 of ages is effective. 2) Long-time running In both sexes the rate of increase is high after they are 15 years old (or after being of 15 ages). To anticipate the good effect of training of long-time running, therefore, it is effective to apply the training after they are 15 years old (or after being 15 ages)

홍성수,이환홍,노재성,조헌영 忠南大學校 産業技術硏究所 1991 산업기술연구논문집 Vol.6 No.2

Aluminum isoproxide was synthesized by aluminum and isoproplyl alcohol and hydrolyzed to make alumina sol. The collodial stability of alumina sol was evaluated by measuring zeta potential. A high purity aluminum isoproxide(>99%) was obtained from aluminum powder, foil and flake. The particle size of aluminum powder was smaller than 250㎛ to obtain 80% yield and up within 6 hours reaction time. The alumina sol was highly stabilized in the presence of acid medium at a hydrolysis condition of pH 3 and water/alkoxide=150 at 65℃. The particle size of alumina powder was mostly under l㎛ after sintering at 1200℃ for 1 hours.

가연성 화학약품 분진(Salicylic acid, terphtalic acid, phenolic resin 및 무수 phtalic acid)의 폭발특성에 관한 연구 : salicylic acid, terphtalic acid, phenolic resin and anhydridephtalic acid

홍성수,노재성 충남대학교 공업교육연구소 1993 論文集 Vol.16 No.1

The explosion characteristics of combustible chemical powders, such as salicylic acid, terphtalic acid, anhydridephtalic acid, phenolic resin, was investigated. The combustible chemical powders have a little difference in explosion characteristics with those of gases. These chemical powders need a special care at industry because the minimum ignition energy of the examined chemical powders was very low. In the presence of inert dust(talcum), the explosion pressure was decreased with the increasing of the added amount of talcum except phenolic resin. The maximum rate of explosion pressure of four chemicals was effectively decreased by inert dust.

Objectives : The purpose of this study was to investigate the prevalence of erectile dysfunction (ED) in a rural area of Korea and to examine the relationship between the prevalence and correlates of subjects. Method : This study was done as a part of the chronic disease survey of rural area by the Asan Foundation. Among 30 years or older population from Jung Eup, a rural area of Korea, 711 male subjects were sampled using a cluster probability sampling method. Trained interviewers visited and interviewed subjects aged 30 years or older with a structured interview. ED was categorized as 'none', 'mild', 'moderate', or 'severe' according to the ability to 'attain and/or maintain an erection satisfactory for sexual intercourse'. Response rate was 54.3% (N=386). Results : The age weighted prevalence of ED was 27.2% (minimal 14.1%, moderate 7.6%, severe 5.5%). Prevalence and severity increased with age. Liver disease and underweight were significantly (p<0.05) associated with ED. Smoking seemed to be correlated with ED, but did not reach statistically significant level. Conclusion : ED was highly prevalent in the rural community of Korea. Medical, sociodemographic, and lifestyle variables associated with ED may alert physicians to patients at risk for ED and offer insight to its etiology.

조혈모세포이식 환자에서 침습성 진균 감염에 대한 이트라코나졸 액과 플루코나졸 시럽의 예방 효과 : 전향적, 무작위, 비교 임상시험

최수미,이동건,최정현,박선희,엄기성,김유진,김희제,민창기,유진홍,김동욱,이종욱,민우성,신완식,김춘추 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

목적 : 조혈모세포이식 환자에서 호중구 감소 기간 동안 이트라코나졸 액(ITZS)과 플루코나졸 시럽(FCZS)의 진균 감염에 대한 예방 효과를 전향적으로 비교해 보고자 하였다. 재료 및 방법 : 2001년 8월부터 2002년 6월까지 가톨릭 조혈모세포이식센터에 입원하여 동종 조혈모세포이식을 받은 만 18세 이상의 환자들을 각각 ITZS와 FCZS군으로 무작위 배정하여 침습성 진균 감염 발생과 약제 관련 부작용을 전향적으로 조사하였다. 결과 : ITZS군에 40명, FCZS군에 38명이 배정되었고, FCZS군 환자의 평균 나이가 더 많았다. 시험 약제 평균투여기간은 ITZS군 16.4일, FCZS군 21.9일로 ITZS군이 더 짧았다. 이는 ITZS군에서 소화기 부작용으로 인한 약제 중단이 더 많았기 때문으로 보인다. 시험 약제 투여 후 총 빌리루빈 수치의 유의한 증가가 관찰되었으나, 약제 관련 부작용은 모든 환자에서 가역적이었다. 호중구감소 기간동안 표재성 진균 감염은 두 군에서 모두 발생하지 않았고, 침습성 진균 감염은 ITZS군 5명(12.5%), FCZS군 8명(21.1%)으로 FCZS군에서 많았으나, 통계학적으로 유의하지 않았고, 사망률에도 유의한 차이는 없었다. 결론 : 침습성 진균 감염에 대한 이트라코나졸 액과플루코라졸 시럽의 예방 효과에 유의한 차이는 없었으나, 앞으로 더 많은 환자를 대상으로 잘 짝지어진 대조군 연구가 필요할 것으로 보인다. 부작용 중 간독성과 관련하여 이식시 투여되는 여러 약제들과의 상호작용에 대한 연구도 필요할 것이다. Background : Though fluconazole is widely used for antifungal prophylaxis, it is ineffective against mould infections including Aspergillus species. Itraconazole has a broader spectrum than fluconazole but the capsule form shows erratic bioavailability in neutropenic patients. In this study, we compared itraconazole oral solution (ITZS) with fluconazole syrup (FCZS) for the prevention of invasive fungal infection (IFI) in allogeneic hematopoietic stem cell transplant recipients. Materials and Methods : Adults receiving allogeneic hematopoietic stem cell transplantation (HSCT) from september 2001 to June 2002, were randomly allocated to either the ITZS group or the FCZS group. We prospectively evaluated the safety and efficacy of each drug. Results : Out of 78 patients (40 patients in the ITZS group and 38 patients in the FCZS group) who were eligible for this study, 37 patients completed the course of prophylaxis without any evidence of IFI. The mean duration of prophylaxis was 16.4 days for the ITZS group and 21.9 days for the FCZS group (P<0.006). Drug-related adverse events occurred in 28 patients (70.0%) and 19 patients (50.0%) in the ITZS group and the FCZS group, respectively. Common adverse events of ITZS were nausea, vomiting, and diarrhea. Drug-related reversible hepatotoxicity occurred in 4 patients in the ITZS group. There was a significant elevation of total bilirubin level in the ITZS group. The incidence of suspected IFI occurred in 5 patients (12.5%) who received ITZS, compared with 8 (21.1%) who received FCZS (P=0.372). There were no proven IFIs or superficial (oral/vaginal) fungal infections in both groups. Overall mortality was not different between the two groups (2.5% in the ITZS group versus 5.3% in the FCZS group, P=0.610). Conclusion : ITZS and FCZS showed similar protection against IFI during pre-engraftment period. Poor tolerability due to gastrointestinal troubles of ITZS might limit its success as prophylactic therapy. Well matched controlled study with large number of patients will be required in the future.
