박수한,김진수 대한공업교육학회 2020 대한공업교육학회지 Vol.45 No.1

The Ministry of Education has been quick to apply National Competency Standars (NCS) to industrial sites and educational · training institutions in order to resolve discrepancies between practical affairs in industrial sites and vocational education, training & requirements. Full implementation of NCS-based curriculum in vocational education of vocational high schools has been mandatory since 2018. This research used a region-stratified sample of 350 from teachers in ‘machinery’ and ‘machine․metal’ majors in mechanical departments of vocational high schools to investigate the awareness of practical courses for metal machining among the teachers. The research results are as follows. First, a majority of the respondents indicated the availability of turning process, milling process, computer integrated manufacturing and measuring courses in mechanical departments. Second, capabilities required by the industry are considered most in selecting practical courses and competence units. Third, positive changes with the introduction of practical courses in the school education are students' practical skills improvement and satisfaction of industrial requirements. Fourth, negative changes with the introduction of practical courses in the school education are too difficult learning modules used in practical courses for students and students’ difficulty in learning because of the difference between equipment in schools and industrial equipment in learning modules. Fifth, teachers’ satisfaction with practical courses classes and overall conditions is above the average, and their satisfaction with the level of practical courses and bookbinding or purchase of rearranged textbooks of practical courses is below the average. Therefore, application conditions of above-mentioned representative 4 practical courses should be examined and taken care of for consistent improvement to stabilize NCS-based educational courses in mechanical departments. 교육부에서는 산업현장의 실무와 직업교육 및 훈련, 자격 내용의 불일치 해소를 위해 국가직무능력표준(NCS)을 활용하여 산업현장과 교육․훈련기관 등으로 빠르게 적용해 나가고 있으며, 2018년도부터 특성화고등학교의 직업교육에 NCS기반 교육과정을 전면 도입하도록 의무화하고 있다. 이 연구는 특성화고의 기계계열인 ‘기계’ 및 ‘기계․금속’전공 교사를 대상으로 350명을 지역별로 유층 표집하여 절삭가공 실무과목 적용에 대한 교사의 인식을 조사하였다. 연구 결과는 다음과 같다. 첫째, 기계관련 학 과에서 선반가공, 밀링가공, 컴퓨터활용생산, 측정과목의 적용률은 전체 응답자 중 대부분을 차지하고 있으며 둘째, 실무과목 및 능력단위 선정 시 고려사항에 대한 교사 인식은 산업체 요구능력이 가장 높다. 셋째, 실무과목 도입으로 인한 학교 교육에서의 긍정적인 변화에 대한 교사 인식은 학생의 실무 능력 향상과 산업체 요구 충족이 가장 높으며 넷째, 실무과목 도입으로 인한 학교 교육에서의 부정적인 변화에 대한 교사 인식은 실무과목 수업에 활용되는 학습모듈의 수준이 학생의 수준에 비해 너무 어렵다는 것과 학습모듈에 집필되어 있는 산업체 장비와 학교 장비가 차이가 있어 수업에 대한 어려움을 느끼고 있다. 다섯째, 실무과목 수업 및 제반 여건에 대한 교사 만족도는 보통 이상이며 실무과목의 수준, 재구성된 실무과목 교재를 제본 또는 구매하는 것에 대한 만족도는 보통 이하이다. 따라서 기계관련 학과의 NCS기반 교육과정의 안정적인 정착을 위해서는 가장 대표성을 띠는 위 4개 실무과목의 활용 실태를 점검하고 지속적으로 개선하는 데 노력해야 한다.

With the management environment of business turning into a knowledge-intensive environment, the evaluation categories of intangible assets, such as, the knowledge of employees, customers and supplies, innovation of management environment, and so forth have become more important over the evaluation of corporate competitiveness through tangible assets. Such an intellectual capital is deemed to be the basis of success and influence on value creation and management performance of companies that it is important to engage in systematic and efficient intellectual capital in a way of contributing to the management performance. Accordingly, the purpose of this study is to contemplate human capital, structural capital and customer capital that comprise the intellectual capital of hotel enterprises and study on influence of intellectual capital on the non-financial performance as its major performance. This study is aimed at formulating the key factors that perceived by the employees regarding the intellectual capital of hotel enterprises and measuring the noticeable influence on non-financial performance. Based on the document studies, the empirical study has been administered with the targets in employees who are engaged in intellectual capital related affairs in hotel enterprises. The intellectual capital of hotel enterprises are presented in structural capital, customer capital and human capital, and it is demonstrated that the intellectual capital of hotel enterprises has made positive (+) influence on non-financial performance

Porous Al metal was produced by batch type casting process. In this foaming process, the viscosity and surface tension of molten Al as two most important factors have been investigated in the temperature range of 680-95$0^{\circ}C$ by the ring method and rotational method respectively. The experimental results showed that both the surface tension and viscosity of the melt decreased linearly with increasing temperature. Addition of Ca decreased surface tension, but increased viscosity significantly.

The purpose of this study is to investigate the liquid- and vapor-phase spray characteristics, such as spray tip penetration and spray angle using gasoline direct injection (GDI) injector with multi-hole. The vapor-phase spray was captured by the Schlieren visualization system, which consists of high-speed camera, LED lamp, concave mirrors, and knife-edge. The liquid-phase spray was visualized by Mie-scattering techniques. Both spray images of vapor- and liquid-phase were visualized under 373 K of ambient temperature, 1 bar of ambient pressure, and 100/200 bar of injection pressure. The energizing duration was fixed at 1.5 ms. From the analysis of experimental results, it revealed that the increased injection pressure induced an early vaporization due to the improvement of droplet atomization. The spray tip penetration and spray angle in vapor-phase were higher than those in liquid-phase. The difference in the spray tip penetration between vapor- and liquid-spray gradually increased with the time elapsed after the injection. Even with the spray angle characteristics, it was found that the difference between the spray angle of liquid and vapor spray gradually grew after they entered steady-state conditions.

In this report, we present a scalp defect reconstruction with lateral arm free flap. We highlight the difficulty in obtaining a recipient vein and the venous drainage managed through an open end of the donor vein. A 52-year-old woman presented with a pressure sore on the left scalp. A lateral arm free flap was transferred to cover this 8×6 cm defect. The arterial anastomosis was successful, but no recipient vein could be identified within the wound bed. Instead, we used a donor venous end for the direct open venous drainage. In order to keep this exposed venous end patent, we applied heparin-soaked gauze dressing to the wound. Also, the vein end was mechanically dilated and irrigated with heparin solution at two hour intervals. Along with fluid management and blood transfusion, this management was continued for the five days after the operation. The flap survived well without any complication. Through this case, we were able to demonstrate that venous congestion can be avoided by drainage of the venous blood through an open vessel without the use of leeches.

우리나라에서 도시지역의 주차문제는 자동차의 급격한 증가와 함께 심각해지기 시작했다. 문제점을 인식하고 주차수요에 대한 대책을 내놓고는 있지만, 지속적인 차량의 증가로 인하여 주차난은 더더욱 심해지고 있다. 이에 따라 주차시설 및 공간의 부족으로, 운전자 및 보행자의 안전 위험, 거주지 접근의 문제, 상업지역 하역 공간 부족, 간선도로 교통혼잡 등을 야기함으로써 사회적 문제가 되고 있다. 이에 차량의 주차공간을 효율적으로 활용하고자, 사물(지자기센서) IoT를 기반으로 차량을 감지하고 주차공간을 알려주는 주차관리시스템을 설계하고자 한다. 본 시스템은 차량의 감지를 위하여 지자기센서 및 IR센서, MCU, 그리고 정보를 전송하기 위한 IoT 통신기술 등이 구성되어 있으며, 사용자에게 정보를 전달하기 위한 프로그램 등이 고안되어 있다.
