Objectives: The aim of this study was to describe the clinical characteristics of enuretic children and to evaluate the efficacy of treatments. Methods: Our study subjects enrolled were 52 children with nocturnal enuresis, who visited outpatient clinic of pediatrics in Seoul Paik Hospital and Ilsan Paik Hospital, during the period from October 1998 to August 2004. The data of gender, age, family history, symptom, clinical type of enuresis and drug therapy were collected and analyzed retrospectively. Results: The male : female ratio was 2.25 : 1. The mean age at diagnosis was 6.8 years with an age range from 4.3 years to 12.5 years. Fourty five cases(86.5%) were diagnosed as primary enuresis and 7 cases(13.5%) were diagnosed as secondary enuresis. A family history of enuresis was noted in 5 cases(9.6%) including 4 cases with parental enuresis history. The accompanying urinary symptoms were urgency(11.5%), frequency (7.7%), and dysuria(2.0%). Conclusion: We found frequent occurrences of enuresis in boys and primary type and an occasional association with a family history of enuresis. The two main treatment modalities were behavior control with an alarm system and drug therapy with imipramine, desmopressin, or oxybutynin. We recommend continuous drug medications to control nocturnal enuresis along with encouragement.

To investigate the effects of short-term administration of DDB(Biphenyl Dimethyl Dicarboxylate) for decreasing elevated serum aminotransferase levels in chronic liver diseases, authors applied 3 capsules of DDB per day at each meal time for 35 patients and compared with 35 patients treated with other conservative management. The following results were obtained. 1. Serum alanine aminotransferase (ALT) levels significantly decreased from 247.1± 180.0 IU/L of pretreatment level to 96.6±126.0 IU/L, 61.1±62.7 IU/L and 38.0±26.8 IU/L after 1, 3 and 6 months of treatment(p<0.05) and effective rates were observed in 60.0%, 71.4% and 88.6% of patients after 1, 3 and 6 months of treatment. 2. Serum aspartate aminotransferase (AST) levels decreased also significantly from 167.8±96.9 IU/L of pretreatment levels to 124.4±155.0 IU/L, 77.9±49.6 IU/L, 60.6± 46.9 IU/L after 1, 3 and 6 months of treatment(p<0.05), but decreasing pattern of serum AST was less significant than that of serum ALT. 3. No significant difference were observed in the serum ALT and AST changes according to the cause and duration of hepatitis. 4. No significant adverse effects were observed in whole patients treated with DDB. It is suggested that small dose administration of DDB is effective for decreasing serum aminotrans ferase levels in chronic liver disease in which other conservative management was not effective.

조영숙,김병진,황대용,강경하 한국농업교육학회 2008 농업교육과 인적자원개발 Vol.40 No.3

이 연구는 농촌사회 속에서 살아가는 성인들의 삶의 현장 속에서 직업을 갖고 살아가는데 주어진 과제를 성공적으로 수행하기 위해 펼요한 핵심역량 수준을 진단하고 개인 특성에 따른 핵심역량 보유수준의 차이를 분석함으로써 핵심역량 향상을 위한 시사점을 탐색하고 제언하는 데 목적이 있다. 이를 위해 선행연구를 바탕으로 개발한 농촌주민의 핵심역량 설문지를 가지고 층화무작위추출(One-Staged Stratified Random Sampling)과 체계적 표집방법을 사용하여 선정된 600명의 장수군 농촌주민을 대상으로 핵심역량을 측정하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, 장수군 농촌주민의 핵심역량은 전반적으로 직업기초능력이 가장 높았고, 그 다음으로 시민의식 능력, 기초문해능력, 직업전환능력, 전문직업능력, 여가문화능력 순으로서 전문직업능력과 여가문화능력이 낮게 나타났다. 따라서 농업기술센터 등 교육기관에서는 전문직업능력과 여가문화능력에 대한 교육 기회 확대나 강화가 펼요하다. 둘째, 6개 핵심역량 보유수준은 직업교육 경험이 없는 층보다 경험있는 층이, 비농가보다 농가가, 여자보다 남자가, 40대 이하와 60대 이상보다 50대에서, 저학력층보다 고학력층, 주부, 무직보다는 농업과 직장인 층에서, 소농보다는 대농과 중농에서 더 높은 것으로 나타났다. 따라서 농촌지역 성인의 현재 직업기초능력 수준을 정확히 진단하고 대상층의 특성과 요구를 명확히 파악하여, 그 결과를 토대로 교육프로그램을 개발하고 제공하는 노력이 필요하다. 이상의 연구결과를 바탕으로 몇 가지 제언을 하였다. 국어 및 컴퓨터 활용 교육 등 기초문해능력 향상을 위한 교육프로그램 개발 및 운영 강화, 자기주도적 학습능력, 문제해결능력 등 핵심역량 향상을 위한 교육프로그램의 개발·운영 등이 필요하다. The purpose of this study was to find core competencies necessary for successful performance of tasks given to rural resident in the age of human resource development and to determine whether the level of core competencies were different according to individual background. For these purpose, we analyzed domestic and foreign literature, and derived core competencies required to rural adult. We surveyed rural resident's perception about their level of vocational competencies. We conducted a questionnaire survey of 600 rural residents living in Jangsu gun sampled by One-Staged Stratified Random Sampling and systematic sampling. The result of this study was summarized as follows. First, rural residents' level of core competencies were generally low. Out of core competencies, basic vocational competency is high, professional competency and leisure culture competency is low. Second the level of core competencies was perceived highly by experienced vocational education, farm house, male, 50's, high educated, farmer and worker, large and middle size farm house. Thus the opportunity for developing the core competencies for these the vulnerable have to be enlarged. Based on the results of this study, we proposed several tasks to be promoted as a part of regional human resources development in Jangsu Gun: 'develop and strengthen education program for basic literacy competency such as literacy and computer', 'expand the opportunity to develop professional competency and leisure culture competency'.

청경채의 엽 형질에 대한 유전분석 : Brassica campestris L. ssp. chinensis Jusl

김영호,이병군,강대성 한경대학교 2005 論文集 Vol.37 No.-

In order to obtain the genetic information on some leaf characters in pak-choi(Brassica campestris L. ssp. chinensis Jusl), diallel cross was conducted using 9 cultivars, and F1, F2 and BC1F1 hybrid lines were developed. Qualitative and quantitative genetic characters related to the three cropping patterns, spring at field, spring in polyethylene film house, and fall at field, were investigated. The results are as follows: 1. A major element related to the expression of leaf green color, and the complementary gene affecting the leaf color at the stage of pigment development were supposed to exist. 2. Heredity of leaf shape was controlled by one major gene that partially dominant, and the oval type was expressed as a dominant at crossing of oval(CR-Cheongdo) with round(Bangjucheong), oval(CR-Cheongdo) with round(Choseonghwakyeong). 3. Inheritance of plant types, erect, semi-erect, and spread, was affected by single gene and the expression of dominant effects increased in order of erect>semi-erect>spread. 4. Heterosis of leaf length, leaf width, midrib length, midrib width and midrib thickness was highly expressed in all cropping patterns. Some characters such as leaf length, number of leaves, midrib length, midrib width, midrib thickness and fresh weight per plant showed significantly positive heterosis at the spring field cropping. The same effect was observed in leaf length, leaf width, midrib length and midrib thickness at the spring in polyethylene film house cropping, and in leaf length, leaf width, leaf shape index, midrib length, midrib width, midrib thickness and fresh weigth per plant at the field cropping in fall. 5. Estimated as a mean heterosis and a heterobeltiosis effects(%), an increase in fresh weigth per plant was attributed to the increase of midrib thickness, midrib width, midrib length, leaf length and leaf width characters. These effects were more significant at the field cropping in fall than spring cropping. Also, hybrid lines showed more late bolting character compared to their parents.

SCM415강의 침탄 표면처리 공정과 기계적 성질

김대욱,김문진,임병수 成均館大學校 科學技術硏究所 1998 論文集 Vol.49 No.2

The influence of plasma carburizing process on the surface hardness of SCM415 low-alloy steel (0.15% C) was investigated under the various process conditions of gas composition, gas pressure, plasma current density, temperature and time. The effective case depth was found to depend on the amount of methan gas containing carbon, thus the deepest case depth and the uniformity of hardeness were obtained under the 100% methan gas condition. The case depth increased with the higher plasma current density which could be increased in the higher gas pressure, because the surface carbon content depends on plasma current density. The effective plasma carburizing temperature of SCM415 steel was found to be higher than 850℃, and the case depth was proportional to the square root of carburizing time under the same current density. The bending fatigue strength of plasma carburized specimen is higher than those of as-received specimen and reheat-quenched specimen. High cycle fatigue and dry wear characteristics of vacuum carburized low alloy steel, SCM415(0.15% C), were evaluated after various heat treatments including direct quenching, single reheat quenching and sub-zero treatment. Comparing the fatigue and wear characteristics of carburized specimens to those of hot annealed or reheat quenched specimens, the wear resistant property as well as bending fatigue limits of vacuum carburized steels were substantially superior to other heat treated steels. Test results indicated that the carburized and reheat treated specimens have higher fatigue limits than the carburized and direct-quenched specimens and the specimens followed by sub-zero treatment. The wear volumes of sub-zero treated specimens with higher surface hardness show slightly lower values than those of non sub-zero treated specimens. This is attributed to the reduction of retained austenite amount of the surface and an increase of surface hardness by the sub-zero treatment effect.

윤대건,이헌창,함병호,조지훈,김태옥 韓國火災 ·消防學會 1998 한국화재소방학회논문지 Vol.10 No.4

나프타분해플랜트의 부탄추출공정에서 부탄증기의 연속 누출에 의한 제트화재와 플래쉬화재의 사고결과에 대한 영향을 평가하고 사고결과에 미치는 공정변수들의 영향을 해석하였다. 877 kPa과 346.75K의 공정조건에서 부탄증기가 87.8 kg/s의 속도로 8m의 높이에서 연속누출되는 경우에 표준조건으로 설정한 대기 및 환경조건에서 사고결과를 해석한 결과, 제트화재에서는 화염의 형태와 크기를 예측할 수 있었으며 누출지점으로부터 200m에서 API모델로 산출한 목사열은 약 5kW/m^2이었고 플래쉬화재가 일어날 수 있는 연소범위는 11.2~120.2m이었다. 그리고 사고결과에 미치는 조업압력의 영향은 조업온도보다 크며 압력이 증가할수록 사고결과 값이 증가하였다. 이때 플래쉬화재에서 X_UFL에 미치는 공정압력의 영향은 X_LFL에서보다 약 1/10이하를 나타내었다. The consequence analysis for jet and flash fire accidents by the continuous release of butane vapor was performed and effects of process variables on consequences were analyzed in standard conditions. For the continuous release(87.8 kg/s) of butane vapor at 8 m elevated height in the debutanizing process of the naphtha cracking plant operating at 877 kPa, 346.75 K, we found that for the jet fire accident, shape and size of the flame could be predicted and thermal radiation estimated by API model at 200 m distance from release point was 1.5 kW/m^2, and that for the flash fire accident, effect range was 11.2~120.2m. Also, simulation results showed that effects of operating pressures on consequences were large than those of operating temperatures and results of accidents were increased with increasing operating pressures. At this time, effects of operating pressures on X_UFL. were smaller

Study on Method of Sperm Aspiration and Injection into an Oocyte in Intracytoplasmic Sperm Injection(ICSI) Immobilization of spermatozoa prior to intracytoplasmic sperm iniection(ICSI) sometimes results in crooked tail and this makes it difficult to aspirate sperm into an injection pipette tail first. Head-first sperm aspiration into an injection pipette avoid this problem due to the bigger size of the sperm head. The effect of head or tail-first sperm injection into an oocyte on fertilization cleavage, percentage of grade I embryos and development to blastocyst stage in ICSI program has been studied. A single living immobilized spermatozoa from oligoasthenozoospermic patient was injected into an oocyte head-first or tail-first according to the treatment. Eighteen hours after microinjection, oocytes ware inspected for survival and fertilization Fertilized oocytes with two pronuclei were cultured in 30μl drop of mHTF supplemented with 10% heat-inactivated follicular fluid(FF) at 37℃. On day 2. embryo transfer was performed with cleaved embryos. The remaining 2-8 cell stage embryos were co-cultured with BRL cells in mHTF + 10% FF for 72 hours and the developmental stage was observed. The data were analyzed by Analysis of Variance. A total of 164 oocytes from 36 cycles were assigned to earth treatment and ICSI was performed(88 head-first, tail-first). The rates of normal fertilization were 81.8% and 76.3% for head-first and tail-first, respectively. Of the fertilized oocytes, the percentage of cleaved embryos and the percentage of grade 1 embryo among cleaved embryos were 88.9% and 68.8%, 93.1% and 74.1% for head-first and tail-first, respectively. Of the 2-8 cell embryos cultured, 44.4%(16/36) and 50.0%(10/20) for head first and tail first, respectively developed to blastocyst stage. There were no differences in fertilization, cleavage, rates of grade 1 embryos, and development to blastocyst stage. In conclusion, head-first or tail-first sperm injection into an oocyte in ICSI program does not affect fertilization and subsequent embryo development to blastocyst stage in vitro.
