Introduction: Transthoracic fine needle aspiration biopsy(TNAB) has shown to be a resonably safe, simple, and accurate procedure in diagnosis of intrathoracic lung lesions. We reviewed the results of 1,005 TNAB of chest lesions performed on 930 patients with 20 or 22-gauze needles over a period of 10 years. Methods: From November 1983 to June 1995, 1,005 cases in 930 patients with an undiagnosed lung lesion underwent TNAB at the Hanyang University Hospital: 66% were men and 34% were women. Most of the patients were 40~60 years old and the youngest patient was 3 years of age. Result: 540 patients had various malignant chest lesions and 322 patients had benign pulmonary lesions. The diagnostic accuracy of TNAB was 96.1 percent in malignant diseases with one false positive result and 90.1% in benign diseases. A definitive diagnosis was not obtained in the remaining 68 patients. The most common diagnoses among 519 malignancy chest lesions with TNAB were the following: squamous cell lung carcinoma, 31.7%; adenocarcinoma, 24.7%; small cell lung carcinoma, 16.7%; metastatic cancer, 14.2%; large cell lung carcinoma, 6.2% and so on. Complications included pneumothorax in 12.3% necessitating chest tube drainage in 0.6%. Minor hemoptysis occurred in 3.6%. There was no death directly attributable to the procedure. Conclusion: We concluded that TNAB permits a direct approach to all kinds of localized lung lesions with a high degree of accuracy and without major complications.

This study is aimed at contributing to the future development of Home Economics Education Department by suggesting basic data of TQM(Total Qualify Management) for evaluating TQM of Home Economics Education Departmeut in education colleges. A survey was conducted involving all junior(3rd year) students of Home Economics Education Department in education colleges either by making a visit to 3 different schools or by sending it in the mail to 10 different schools. Responding answer-sheets, 302 copies(88.3%) out of 342 copies in total were returned. Finally, we used 285 copies(83.3%) as data for analysis. The results of this study are as follows: In terms of Professional Qualification of Home Economics Teachers, the students had passion for their Home Economics Education and also had a great pride and mission to be future Home Economics teachers. However, their ability proved to be poor and low in presenting a vision for Home Economics, in conducting extra-curricular activities, and the computer skills. In the case of college students, their satisfaction showed an average point 3.15 on a scale of 5. Those students who entered school voluntarily or those who hoped for re-entrance showed more satisfaction than those who entered school with good academic records or those who do not hope for re-entrance into school. In terms of professors' leadership, Students are perceived to choose 'Transactional Leadership' instead of 'Transformational Leadership'. Students', who have higher satisfaction and hopes for re-entrance, perception level about their professors' leadership style showed higher satisfaction than average. The students empowerment level showed average point 3.52, which is considered relatively high. Students at the college where professors majored in Home Economics Education are employed showed higher empowerment level than students at the college with professors who did not major in Home Economics Education. The result of evaluating general demand for renovating of Home Economics Education Dept. showed that: they perceived the "Teacher Education Course" of Home Economics Education Dept. as in need of cultivating practical skills in secondary school. They also said, "Teaching Method" is in great need of renovation. In the case of teaching method, they preferred laboratory work, and practical training. In earning credits, they emphasized the importance of faithfully completing the "Study of Content". For the Subject Matter Education, they required a training course to be set up in the secondary school. Finally they claimed that the teachers and students need to take the initiative in developing a Curriculum of Home Economics Education Dept. Based on the findings mentioned above, I would like to suggest further research on how to adopt and evaluate TQM in Home Economics Education, and faculty-centered evaluation methods. I also would like to suggest to vitalize quality research through the form of narrative research.

우리나라는 수자원장기종합계획과 유역종합치수계획의 수립을 통해 수자원의 개발, 안정적인 공급과 효율적인 배분, 홍수재해방지 등을 위한 많은 노력을 해왔다. 최근에는 수자원의 관리효율화, 체계적 통합적으로 시행하고자 수자원법을 제정하여 수자원 관리의 체계를 개편하였으며, 향후 지자체 중심의 정량적인 물수급평가를 통해 현실적인 결과와 대안을 마련하는 것이 필요하다. 기존의 용수공급능력 평가와 물수급계획은 시 군 중심의 용수수요량을 바탕으로 중권역 단위로 확장하고, K-WEAP(Korea-Water Evaluation And Planing System) 모형을 활용하여 용수수급전망을 제시하고 있다. 이에 본 연구에서는 한강 권역을 중심으로 기존 계획에서 활용한 K-WEAP과 국내 외 활용도가 높은 MODSIM(Modified SIMYLD)을 활용하여 각 모형에 대한 입력자료, 내부 계산 알고리즘 및 분석방법 등 모형의 적용성을 검토하여 중권역 기반의 물수급 분석 결과를 비교 하였으며, 향후 모형 적용 시 고려사항 및 발생 가능한 오류를 최소화 할 수 있도록 하고자 하였다. 분석 결과, 기존 수자원장기종합계획에서 활용한 K-WEAP모형은 생 공 농업용수가 모두 동일우선순위이나, MODSIM모형에서는 수요지별 우선순위를 고려해야 하므로 상 하류간, 생활 공업, 농업으로 우선순위를 부여할 경우 물 부족량의 차이가 발생하였다. 우선순위 적용시 K-WEAP과 형과 MODSIM을 비교할 경우, 유사한 물부족량과 시점을 제공하고 있어 적용성과 분석결과의 일관성을 확인할 수 있었다. 또한 같은 물부족 결과를 제공하는 조건의 검토 수행 시간 측면과 모형구동 결과의 안정성에서 MODSIM이 더 우수한 것으로 분석되어 향후 지자체 중심의 세부적인 물수급평가를 위해서는 빠른 의사결정을 도울 수 있을 것으로 판단된다.

Promoting job growth and quality has been central to developing countries to reduce poverty for decades. In this regard, Nepal is not unique in its need to develop effective TVET programme as it is considered showing positive association with workforce development and productivity. While the copious academic literature has highlighted upon staff training programme in general education, it encounters lack of adequate attention in the field of TVET education. The purpose of the study is to identity and prioritise the professional development needs for the teachers of TVET sector in Nepal. A sample(N=317) of Nepalese teachers from seven provinces were asked to answer the scale. The Borich needs assessment model was employed to assess the perceived level of importance and present preferred training modules among 29 teaching subjects. Moreover, a quadrant analysis using 2×2 matrix was used as a diagnostic tool to denote overriding training topics. The result shows that following competence skills constructs were perceived to be in high need of enhancement as well as in existence of discrepancies: 'occupational characteristics of TVET trainer', 'training needs analysis and curriculum development', 'curriculum development based on national competence standard(NCS)', and 'Institution management evaluation'.

This study compared the characteristics of the optimization technique and the water supply and demand forecast using K-WEAP (Korea-Water Evaluation and Planning System) model and MODSIM (Modified SIMYLD) model considering wtaer supply priority. Currently, The national water resources plan applied same priority for municipal, industrial and agricultural demand. the K-WEAP model performs the ratio allocation to satisfy the maximum satisfaction rate, whereas the MODSIM model should be applied to the water supply priority of demands. As a result of applying the priority, water shortage decreased by an average of $1,035,000m^3$ than same prioritized results. It is due to the increase of the return flow rate as the distribution of Municipal and industrial water increases. Comparing the analysis results of K-WEAP and MODSIM applying the priorities, the relative error was within 5.3% and the coefficient of determination ($R^2$) was 0.9999. In addition, if both models provide reasonable water balance analysis results, K-WEAP is superior to GUI convenience for model construction and data processing. However, MODSIM is more effective in simulation time efficiency. It is expected that it will be able to carry out analysis according to various scenarios using the model.
