본 연구의 목적은 사회복지조직의 공개 채용공고가 실제채용기준을 얼마나 반영하고 있는지 파악하여 채용공고의 변화가능성을 탐색하기 위함이다. 이러한 목적을 달성하기 위해 2008년 한국사회복지사협회의 채용공고 중 210건의 조직을 표집하여 기초분석을 통해 정보내용을 파악하였고, 서울과 대전의 23개 조직의 기관장을 대상으로 1:1면접을 통해 사례연구를 진행하였다. 분석결과, 실제채용기준은 자원봉사와 실습을 통한 현장경험, 사회복지사 1급 자격증, 지원자와 조직의 비전 일치, 사회복지 마인드, 대인관계 등으로 드러났다. 그러나 이는 채용공고에 제시되지 않거나 질적인 차이를 보였다. The purpose of this study is to understand how an open employment notice has reflected the actual criterions of the recruitment, and to discover a potential for any changes. To achieve this purpose, a systematic random sample of 210 open employment notices was selected from Korea Association of Social Workers in 2008, and a descriptive analysis was conducted. The qualitative research was carried out for the case study with 23 interviewees from social welfare organizations in Seoul and Daejeon. Consequently, the actual criterions of the recruitment included the following elements: social work field practicum and volunteer work, the level one social welfare license, degree of harmony with the vision of the organization, dept of social welfare-oriented mind, and human networks. However, these criterions may not be presented in open employment notices or show that there are qualitative differences between open employment notices and the actual employment criterions.

國民學校 兒童의 姿勢에 관한 硏究 : 脊柱의 彎曲과 側彎을 中心으로 Spinal Curvature and Side Curvature

姜信和 진주여자전문대학 1984 論文集 Vol.6 No.-

Taking account a posture (especially the spinal column) is on the basis of one s body, having a poor figure- spinal curvature, side curvature, etc-is considerable a main cause which check one s growth, injure one s health, and decrease operation efficiency. At the result of survey primary school children's (age 6, age 10 ) spinal curvature and side curvature, 1) I found that spinal curvature of Children is more in the younger than older-children and front spinal curvature of children is more than backward spinal curvature. 2) I found that side spinal curvature of children is more in the schoolboys than the schoolgirls, and right-sided curvature is more left-sided, and the younger has more than older. It is desirable that the first- line educators discover earlier the wrong curvature and side curvature etc. and all we must endeavor to educate keeping a straight posture from the early little, with filling up various implements which are suitable for children's growth.

This study aimed to compare analgegic efficacy, satisfaction score and side effect of nalbuphine-ketorolac and butorphanol-ketorolac by using intravenous patient controlled analgesia(IV-PCA) for postoperative anlgesia following a gastrectomy for stomach cancer. Ninety patients who had undergone gastrectomy for stomach cancer under general anesthesia were randomly divided into two groups. Each group recieived nalbuphine 50mg with ketorolac 150mg(Group 1, n=45) and butorphanol 5mg with ketorolac 150mg(Group 2, n=45) by using IV-PCA during postoperative 48hrs. Assessments for pain with numerical rating scale(NRS), and side effects were evaluated at 2hr, 6hr, 12hr, 24hr, 36hr and 48hr after the operation. There were no significant difference in NRS for pain during rest, but Group 2 requested significantly greater amount of supplementary diclofenac during first 24 hours. Side effects were higher Group 1 in pruritus, nausea and vomiting and Group 2 in sedation, nausea and vomiting. This study suggests that adding ketorolac with intravenous nalbuphine or butrophanol in using an intravenous PCA can decrease analgesics requirement and improve analgesic property without the major morbidity like respiratory depression, but needs for the careful observation and treatment on the side effects like nausea. vomiting, pruritis and sedation...

잠재적으로 기능을 갖는 마우스 칼리크레인 유전자(mGK-21) 클로닝과 그 특성에 관한 연구

김화선,이희섭,김원신 원광대학교 생명공학연구소 1996 생명공학연구소보 Vol.4 No.1

Mouse glandular kallikreins are a highly homologous subfamily of serine proteases encoded by 25 genes, all located on chromosome 7^((8)). By protein and cDNA sequence analysis, it was demonstrated that prorenin converting enzyme(PRECE) in the ICR mouse submandibular gland is identical to the epidermal growth factor-binding protein(EGF-BP) type B, the mouse Grandular Kallikrein-13(mGK-13) gene product identified Balb/c^((10, 11)). To examine whether the mGK-21 which cleaves the mouse pro-mouse glandular kallikrein-21(mGK-21) to its mature form is involved in the processing of prorenin, We have cloned the cDNAs of the mGK-21 from a library of male ICR mouse submandibular gland(SMG) and determined the sequences of the cDNA of mGK-21. And then Chinese Hamster Ovary(CHO) cells were transfected with the mGK-21 expression plasmids, and stable cell lines expressing a high level of the mGK-21 precursor were obtained. The conditioned medium from CHO/GK21 cells was then treated with trypsin, since trypsin is known to activate prokallikrein. Therefore, We treated the conditioned medium of CHO/GK21 cells with trypsin, which has been demonstrated to effectively convert the pro mGK-21 to enzymematically active form. Then, the radiolabeled-conditioned medium of CHO/MRB cells, which stablely express mature Ren-2 prorenin, was incubated with the trypsin-treated CHO/GK21. In vitro translation, the product of mGK-21 cDNA was detected and in the northern blotting, mGK-21 were expressed in submandibular gland. In the present study, even though the recombinant mGK-21 do not show a prorenin converting activity, it is apparent that they may possess a serine protease activity.

정상화,이규태,장완식,류신호 朝鮮大學校 機械技術硏究所 2001 機械技術硏究 Vol.4 No.2

실제 운동조건과 같은 환경을 제공하는 다축 제어용 시뮬레이터는 설계나 평가에 있어 대단히 편리하면서도 경제적인 이점을 제공하여 준다. 일반적으로 완성차의 경우 설계에서부터 개발, 실험에 이르기까지 시간과 개발과정에 막대한 비용이 소모되고 있다. 그리고 자동차 부품업체에서는 완성차업체의 부품 검사서의 요구에 의해 시뮬레이터를 구비하고자 노력하고 있으나, 재현소프트웨어의 미비로 어려움을 겪고 있는 실정이다. 본 논문은 개발된 프로그램을 이용하여 기아자동차의 내구로(belgian road), 대우자동차의 도시로(city road), 고속도로(highway), 자갈로(gravel road)등의 신호를 입력하여 실제 실험을 수행함으로서 로드 프로파일 재현 소프트웨어의 타당성을 검증하였다. 이 과정에서 실험차량의 현가장치와 타이어가 비선형이기 때문에 초기 구동화일에 대한 응답신호는 요구되는 신호와 차이가 발생하였는데 이 오차는 반복 개선작업을 통하여 최소화시키면서 응답신호가 요구신호에 일치하도록 반복작업을 되풀이하였다. Full scale durability test in the laboratory is an essential of any fatigue life evaluation of components or structures of the automotive vehicle. Component testing is particularly important in today's highly competitive industries where the design to reduce weight and production costs must be balanced with the necessity to avoid expensive service failure. Generally, Hydraulic road simulator is used to carry out the fatigue test and the vibration test. In this paper, the algorithm and software to realize the real road profile are developed. The operation software for simultaneously controlled 3-axial simulator is developed and the input and output data are displayed window based PC controller in the real time. Futhermore, the software to generate the real road profile are developed. The validity of the software are verified by applying the belgian road, the city road the highway, and the gravel road. The results of the above experiment show that the real road profiles are realized well after 10th iteration. .
