        瓔幼兒의 授乳 및 補充食에 對한 都市地域 어머니들의 知識 및 實踐에 關한 調査硏究

        沈在英 韓國保健敎育學會 1987 보건교육건강증진학회지 Vol.4 No.1

        The main objectives of the present study were to understand the knowledge and practice of breastfeeding mothers about the feeding and supplementary food and to analyze the factors related to it. The data for the present study collected from July 9 to July 31, 1984 for 302 mothers in Seoul. 1. The Knowledge of Breastfeeding Mothers about the feeding and Supplementary Food (1) In the knowledge of mothers on the appropriate feeding pattern before 6 month, 69.3% of total women believed that breast-fed babies are healthier. There was a significant difference in the type of feeding in order to education level, socio-economic state, and mass-media exposure. (2) In the knowledge of mothers on an appropriate duration of lactation, the mean duration of breastfeeding is 8.1 month. The duration of breastfeeding gradually decreases in order of education level, socio-economic state, mass-media exposure, and employment status. (3) In the knowledge of mothers on an appropriate time of introduction of supplementary food, the mean time of introduction of supplementary food is 4.7 month. It is gradually decrease in order of education level, socioeconomic state, mass-media exposure, and employment state. 2. The Practice of Breastfeeding Mothers about the Feeding and Supplementary Food. (1) The practice of mothers on infant-feeding before 6 month and that education level, socio-economic state and mass media exposure are the higher, the rate of breast feeding is the less. (2) The mean duration of breastfeeding is 9 month. It is 1 month longer the knowledge of mothers on an appropriate feeding pattern before 6 month. (3) The time of introduction of supplementary food is average 4.75 month. It is similar to the knowledge of mothers on an appropriate time about introduction of supplementary food. The result of this study indicate that the knowledge and practice of breast feeding is maintained comparatively high in low educated group, whereas it is noticeably decreasing among the high educated group. High educated group believed that the short duration of breastfeeding better than long, and they practiced breastfeeding so short period. And high educated group also thought early introduction of supplementary food is good for the babies health. Consequently, in this study, for the most part, elite group is found to have rather wrong opinions and practice about infant nutrition. Therefore the accurate information of infant nutrition is must be encouraged to mothers.

        대장 상피종양에서 Cathepsin B, H, L 발현의 의의

        심재영,이미자,기근홍 대한병리학회 2009 Journal of Pathology and Translational Medicine Vol.43 No.5

        Background : Cathepsin is associated with tumorigenesis, tumor invasion and metastasis through its ability to induce degradation of extracellular matrix components. Methods : To investigate the correlation between cathepsin expression and tumor progression, invasion depth or nodal metastasis, immunohistochemical staining for cathepsins B, H and L were done on 20 hyperplastic polyps, 48 adenomas, and 67 adenocarcinomas of the colon. Evaluation of the expression of cathepsins B, H and L was based on the percentage of neoplastic cells that stained positive for any given cathepsin. Results : Cathepsin B expression was significantly higher in adenocarcinomas than adenomas (29.33 vs 5.48%), but was not associated with the degree of differentiation, depth of invasion and nodal status of the tumors. Expression of cathepsins H and L was absent or low in both adenomas and adenocarcinomas. Conclusions : We suggest that cathepsin B is involved in progression of a subset of colonic adenomas, while cathepsins H and L are not.

        Genistein이 MG-63 조골세포의 증식과 세포외 기질형성에 미치는 영향

        심재영,김인혜,엄애선,백민경 대한암예방학회 2009 Journal of cancer prevention Vol.14 No.1

        We investigated the proliferation and extracellular matrix formation effects of genistein on MG-63 cell, human osteoblast like cell. The cells were treated with 1μM, 10μM, 100μM of genistein for 12 h, 24 h, 36 h, 48 h in order to determine the proliferation rate. The growth rate in control group increased up to 36 hours and then decreased at 48 h. Meanwhile, its rate increased rapidly up to at 24 h and then declined at 48 h by treating genistein. The effective time and concentrations of genistein for MG-63 cell was a 12 h and 10μM∼100μM, respectively. ALP and OC mRNA, initial bone proliferation marker, were strongly expressed by increasing concentration of genistein. The expression of Matrix metalloproteinase (MMP)-13, a collagenase involved in extracellular matrix degradation, and tissue inhibitor of metalloproteinase (TIMP)-1 elevated at 10μM of genistein. Based on the results, genistein may affect the proliferation of osteoblast on MG-63 cell in initial time and increased the mineral deposition in the extra cellular matrix. Thus, genistein can play role in preventing bone loss during the initial osteoblast proliferation step and in promoting bone formation by inhibiting bone resorption which resulted from stimulation of the initial osteoblast proliferation due to the increased expression of ALP, OC, MMP-13 and TIMP-1.

        Comparison of Pd, Pt and Pt/Pd as Catalysts for Hydrogen Sensor Films

        심재영,이재동,진정모,정현식,이세희 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.6

        Hydrogen has been attracting much interest recently as a source of clean and sustainable energy. However, the volatility of hydrogen, its tendency to explode at concentrations as low as 4 % in air, requires a reliable sensing technology for safe hydrogen utilization. An optical hydrogen safety sensor based on gasochromic thin films can detect a change in color of the film upon exposure to hydrogen gas in an area where a hydrogen leak is suspected. In this study, we compared the sensitivity and the durability of hydrogen sensor films of Pd/WO3, Pt/WO3, and Pt/Pd/WO3. The change in the optical transmittance of the films was measured as these films were repeatedly exposed to hydrogen and air.

        Chlorella Vulgaris May Have Protective Effects on Bioelement Metabolism in Cadmium Exposed Rats

        심재영,신혜성,김병곤,한재갑,하월규,Ae-Son Om 대한암예방학회 2009 Journal of cancer prevention Vol.14 No.2

        We investigated the effects of Chlorella vulgaris (CV) on cadmium (Cd) status and mineral (Zn, Cu, Fe, Ca and Mg) contents in Cd-administered rats for 8 weeks. Forty male rats (5 weeks old, n=10/group) were given control tap water or tap water containing 10 ppm of CdCl2 ad libitum. They were divided into a control group and 3 experimental groups consisting of a Cd (Cd/CV0%) group or a 5% of CV (Cd/CV5%) group or a 10% of CV (Cd/CV10%) group. The concentration of Cd, Ca, Fe, Mg, Cu and Zn in the serum, liver, kidney, spleen, urine and feces were measured by Inductively Coupled Plasma (ICP-MS). The results showed that body weight gain in a control and CV-treated groups were significantly higher than that in Cd/CV0% group. The relative liver and kidney weight are significantly decreased by CV treatments. Cd levels in liver and the kidney and feces were in dose-dependent manner. Cd level in CV-treated groups was decreased while Ca, Fe, Mg and Zn concentration was increased in liver and kidney. On the other hand, Cd was more excreted in CV-treated groups than in Cd/CV0% group. Thus, CV may have beneficial effects on excretion of Cd and retention of divalent metals.

        과학영재와 일반학생의 목표지향성 차이에 관한 연구

        심재영,박병기,김언주,김금희 충남대학교 인문과학연구소 2007 인문학연구 Vol.34 No.1

        <Abstract> A study of achievement goal orientation for the science gifted student Shim, Jae-young․Bak, Byung-gee․Kim, Ohn-joh․Jin, Jin-ji The purpose of this paper aimed to study achievement goal orientation that distinguishes three groups. A questionnaire examining achievement goal orientation was carried out on141 students who were admitted into a gifted high school in science(group A), 70 who were disqualified from the entrance examination of the school(group B), and 212 from a regular school(group C). The result showed that both the achievement goal orientation showed no statistical differences between group A and group B. However, the two groups both indicated a significantly higher level of achievement goal orientation than group C. Therefore, we can reach the following conclusions. Firstly, if there indeed exists no difference in achievement goal orientation between the 216 students who went through the 3rd phase of the admission procedure(group A and group B), the procedure needs to be reexamined over whether too much effort and expense is going into it comparative to the outcome. Secondly, it could have been that the two groups are both highly achievement goal orientation as to show no difference on a simple test. Lastly, one might question the validity of comparing the results from the achievement goal orientation used in the KSA admission procedure in that they are two entirely difference tools that differ in methods of approach.

        정부회계기준의 이원화의 적합성에 관한 연구

        심재영 한국정부회계학회 2011 정부회계연구 Vol.9 No.1

        본 연구는 정부회계기준을 중앙정부와 지방정부로 이원화(분 리 )하여 운영하는 것이 재무보고목적에 비추어 적합한지를 구명한다. 현재 우리나라는 중앙정부와 지방자치단체의 회계기준으로 이원화하여 운영하고 있는데 일원화(통 합 )하 여 운영해야 한다는 의견이 있다.회계기준의 분리는 그 회계실체의 재무보고목적에 영향을 받고, 재무보고목적은 그 실체의 운영환경과 정보이용자와 그들의 정보욕구에 영향을 받는다. 따라서 본 연구에서는 정부의 운영환경, 정보이용자와 그들의 정보욕구, 재무보고의 목적을 지방정부, 중앙정부, 공공부문으로 구분하여 비교·분석함으로써 정부회계기준의 분리가 적합한 지를 분석하고자 한다. 분석의 자료는 지방정부, 중앙정부, 공공부문을 대표할 수 있는 대표적인 정부회계제정기관인 미국의 정부회계기준위원회, 연방정부회계기준자문위원회, 국제공공부문회계기준위원회에서 발표한 공표물들을 사용하였고, 이들 정부회계제정기관의 설립목적과 특징에 대해서도 비교·분석하였다.분석의 결과 정부의 운영환경, 정보이용자와 그들의 정보욕구, 재무보고의 목적, 정부회계제정기관의 설립목적과 특징에서 정부회계기준을 중앙정부와 지방정부로 분리하여야 할 이론적 근거를 발견하지 못했다. 따라서 정부회계기준을 원칙중심의 회계기준으로 하여 통합하는 방향으로 나갈 것을 제안하였다.

        지방자치단체 회계교육의 성과와 과제

        심재영 한국정부회계학회 2006 정부회계연구 Vol.4 No.1

        2004년부터 발생주의와 복식부기에 기준한 지방자치단체회계교육이 전문교육과 소양교육으로 나누어 본격적으로 실시되어 오고 있다. 2005년까지 4,300여명이 전문교육을 받았고, 20,000여명이 소양교육을 받았다. 전반적으로 볼 때 복식부기담당 실무자에 대한 교육은 어느 정도 표준화되어 있고 효과가 있는 것으로 보이나 회계관련 직무당담자, 중간관리층이나 최고관리층, 의회의원에 대한 교육은 취약한 것으로 보인다.개선을 위해서는 먼저 타겟그룹의 수를 세분하고, 그룹별로 적합한 교육훈련전략을 수립하여 하여야 하며, 타겟그룹별로 적합한 표준교재를 더 많이 개발해 나갈 필요가 있다. 다음으로 교육의 초점을 기록과정보다 인식·측정·보고과정과 관련하여 회계학적 사고의 틀을 형성할 수 있도록 유도할 필요가 있다. 교육과정상에서는 윤리교육, 자산관리, 회계감사, 원가관리, 기금회계, 기업회계기준 교육을 보강하여야 하고, 교육방법에서도 내부교육이나 사이버강의, 상호교차교육, 계속교육을 고려하여야 한다.전문가 풀이 매우 취약한 현상황하에서는 전문교육은 정부회계실무 전문가들을 활용하고, 소양교육은 대학교수들을 활용함으로써 교육의 효과를 높일 수 있다고 판단된다. 또한 공무원의 자발적인 학습을 유도하고 교육비용을 줄이는 방법으로 자격증제도나 각종시험에 정부회계과목의 포함이 검토되어야한다. 궁극적으로는 취약한 전문가 풀을 늘리는 방안을 적극 강구하여야 하여야 한다. 이를 위해 회계학교수들에 대한 적극적인 홍보가 필요하다.
