The purpose of this study is to illuminate the influence happened by the process of acquirement of professional cooking skills related to satisfaction with duty of hotel cooks according to the development and expansion of the food service industry. First, interaction with colleagues, working environment, accomplishment of duty, satisfaction of duty etc. have a big effect on improvement of cooking skills, that is, acquirement and accumulation of cooking skill. Therefore, it's confirmed that improvement of skill can be promoted if we focus on this kind of factors and meet more positively. Second, field education training should be operated professionally with systematic education training. Third, duty rotation has an effect on skill advancement. It can be interpreted that oppressive feelings caused by ability, skill, knowledge, human relations etc. which is required in new business related to frequent change of the business in one's charge can have an effect on duty satisfaction. It's considered that comprehensive and in-depth study should be accomplished in future concerning duty rotation, field training.

This paper aims to investigate how and to what extent FDI impacts the relative demand for skilled labor within firms in the case of developing countries. The analysis uses a sizeable micro-level dataset for Malaysian manufacturing industries using the System-GMM estimators to control the estimations' endogeneity problems. For this purpose, the study uses foreign equity share at the firm level to investigate foreign ownership effects at the firm level and the Horizontal FDI index by Smarzynska Javorcik (2004) to analyze FDI intra-industry linkages influence on the structure of labor demand for Malaysian domestic firms. Our findings indicate that foreign ownership increases the skilled demand within Malaysian manufacturing through the learning process, exclusively for small- and medium-sized firms (SMEs). Conversely for foreign-owned firms, changes in their skilled-labor share do not associate with changes in firm-level foreign equity share. We conclude that foreign ownership per se is not the major contributing factor for skill upgrading in Malaysian manufacturing firms. Furthermore, the competitive pressures caused by foreign firms' presence within the same industry - namely horizontal FDI - has a significant negative spillover effect on the level of skilled-labor share for domestic firms in the Malaysian manufacturing sector within periods of the understudies.

Air spring for railway rolling-stock is a part of secondary suspension system which play the role of supporting load, damping vibration. Recently, air springs are actively applied to railway rolling-stock to substitute coil spring with upgrading the manufacturing skill. This study is started to get the fundamental datum related to air spring for the purpose of developing the test draft for air spring. To analyze the performance of air spring, we conducted the simulation for railway rolling-stock applied air spring and tested train in convention lines. Thus, we have obtained useful datum to develop the test draft for air spring. Here, we describe some results.

Air spring for railway rolling stock is a part of secondary suspension system, which is supporting load, damping vibration. Recently, air springs are actively applied to railway rolling stock to substitute the coil spring by upgrading the manufacturing skill. This study is started to develop draft for the testing methods of air spring for railway rolling stock. We have tested several items on testing methods to guarantee the performance of air spring. Thus, we have developed the test draft for air spring.

"Ubiquitous sensor network" definition is this-Someone attaches electro-magnetic tag everything which needs communication between man to man, man to material and material to material(Ubiquitous). By using attached every electro-magnetic tag, someone detects it's native information as well as environmental information such as temperature, humidity, pollution and infiltration information(Sensor). someone connects it realtime network and manage generated information(Network). 21st century's war is joint combined operation connecting with ground, sea and air smoothly in digitalized war field, and is systematic war provided realtime information from sensor to shooter. So, it needs dramatic development on watch reconnaissance, command and control, pinpoint strike etc. Ubiquitous computing and network technologies are essential in national defense to operate 21st century style war. It is possible to use many parts such as USN combined smart dust and sensor network to protect friend unit as well as to watch enemy's deep area by unmanned reconnaissance, wearable computer upgrading soldier's operational ability and combat power dramatically, RFID which can be used material management as well as on time support. Especially, unmanned watch system using USN is core part to transit network centric military service and to get national defense efficiency which overcome the dilemma of national defense person resource reducing, and upgrade guard quality level, and improve combat power by normalizing guardian's bio rhythm. According to the test result of sensor network unmanned watch system, it needs more effort and time to stabilize because of low USN technology maturity and using maturity. In the future, USN unmanned watch system project must be decided the application scope such as application area and starting point by evaluating technology maturity and using maturity. And when you decide application scope, you must consider not only short period goal as cost reduction, soldier decrease and guard power upgrade but also long period goal as advanced defense ability strength. You must build basic infra in advance such as light cable network, frequency allocation and power facility etc. First of all, it must get budget guarantee and driving force for USN unmanned watch system project related to defense policy. You must forwarded the USN project assuming posses of operation skill as procedure, system, standard, training in advance. Operational skill posses is come from step by step application strategy such as test phase, introduction phase, spread phase, stabilization phase and also repeated test application taking example project.

대학생 기초학습능력 미흡은 대학교육의 질 저하를 초래한다는 점에서 전문대학이 안고 있는 주요 이슈 중의 하나이다. 그동안 기초학습능력 향상을 위해 많은 대학에서 노력해 왔으나 해결책이나 개선방안이 뚜렷하지 못한 실정이다. 본 논문은 기초학습능력을 개선하려는 선행연구들이 시도한 노력의 연장선상에서 관련 문헌들을 고찰하고, 국내 전문대학의 기초학습능력 지원 및 운영사례를 벤치마킹하였다. 또한, D 대학을 대표사례로 선정하고 기초학습능력 수준에 대한 교수들의 인식 및 학생의 자기진단, FGI(Focus Group Interview) 등을 실시하여 기초학습능력 향상을 위한 방안을 제시하고자 하였다. 연구결과, 선행연구들과 마찬가지로 D 대학의 경우에도 기초학습능력(언어영역)에 대한 교수들의 기대 및 현재 수준 간 차이가 있었으며, 학생들의 사전 자기진단 역시 유사한 결과를 보였다(교수 기대수준 3.13, 교수 현재수준 2.14, 학생 자기진단 2.37). 본 연구수행을 통해 도출된 문제점과 시사점을 토대로, 역량기반 교육과정으로의 개편(전공교과와 기초핵심역량과의 연계, 기초핵심역량 습득을 위한 교수법 적용, 기초학습역량 교과목 운영), 기초학습 미흡 학생 지도 개선(언어능력 향상을 위한 교수-학습법 적용, 수준별 교수-학습 자료개발, 자기주도적 학습법 전파, 전공동아리 활성화) 및 기초학습능력 진단 평가 시스템 구축(타당도 높은 진단도구 개발 및 적용, 긍정적 진단문화 형성)을 개선방안으로 제안하였다.

플라스틱 사출성형제품은 금형을 제작하여 대량생산에 적합한 시스템으로서 두께가 두꺼운 자동차 핸들제품은 가스사출성형을 수행하는 것이 바람직하다. 가스사출성형은 용융된 원재료를 금형내로 충전시킨 후 질소가스를 주입하는 기술이다. 가스사출성형은 재료비절감, 품질향상 등 많은 장점을 가지고 있다. Moldflow소프트웨어를 활용하여 사출성형 공정을 해석하여 제품의 휨 변형을 최소하기 위한 게이트의 위치를 결정하였으며, 기존의 일반적인 PP재료로 가스사출 성형을 했을 경우 변형이 크게 발생되므로 미네랄이18% 함유된 PP 재료로 변경하여 사출제품의 휨 변형을 최소로 하는 것과 게이트의 위치를 변경하여 핑거링현상이 발생하는 트러블을 제거하는 것을 목적으로 하였다, 또한 가스 사출성형을 수행하였을 경우 원재료가 유입되고 난후 게이트를 기준으로 가스가 유입된 형상을 파악하기 위해 비교분석해 보았다. 본 연구를 통해 제품형상에 따른 두께의 변화와 가스사출성형을 수행하더라도 플라스틱의 재료에 따라 제품의 휨이 발생 될 수 있다는 것과 게이트의 위치가 제품의 트러블에 영향을 미친다는 것을 알 수 있었다.
