본 연구는 숲해설가의 직무만족 향상과 효율적인 조직운영을 위한 기초자료제공을 목적으로 숲해설가의 직무만족도와 관련변인에 따른 직무만족도 차이를 분석하였다. 첫째, 전체직무만족도는 평균 3.41점(5점 만점)으로 직무자체에 대한 만족도는 중위수보다 높은 것으로 나타났으나 복리후생에 관한 만족도는 상대적으로 낮은 것으로 조사되었다. 둘째, 직무만족도 요인분석결과 조직분위기, 보상수준, 직무갈등, 근무여건 네 개의 요인으로 분류되었고 조직분위기와 근무여건 요인에 대한 만족도는 높고 보상수준의 만족도는 낮은 것으로 나타났다. 셋째, 전체직무만족도는 소속기관, 활동현장, 근무경력에 따라 차이가 있는 것으로 나타났고, 직무만족도 하위요인의 경우 조직분위기는 근무경력과 소속기관에 따라 차이가 있었고 보상수준은 소속기관, 근무여건은 소속기관과 활동현장에 따라 유의한 차이가 있었다.

This study aims to improve the uniform functionality of the workers who work in Electric Technology Division, Korea Railroad Corporation. Former study of questionnaire survey was taken to examine the current state of wearing working clothes for the workers. Based on the results of the former study, an experimental clothes, the functionality of which has improved in terms of design, materials, and patterns, was created, and existing working clothes and the treated experimental clothes were compared through simulation wearing evaluation comprising appearance, activity adaptability, quantitativeness, and on-site adaptability evaluation comprising appearance and activity adaptability. The followings are the results of the study: Simulation wearing evaluation is composed of 5subjects and 11experts specializing in costume, and as a result of evaluation the experimental clothes were evaluated superior to the existing working clothes in all items. On-site adaptability evaluation was conducted by workers in the Electric Technology Division, who are the subjects in this study. In that evaluation, the experimental clothes were also evaluated superior to the existing working clothes in all items. While the five subjects who participated in the simulation wearing evaluation move, the quantitative evaluation measured the distance of location transfer of the back length in the jacket and the distance of location transfer of the back waist in the trousers. As the distances in the experimental clothes were measured shorter than the distances in the existing working clothes, the subjective evaluation results are objectively supported.

In recently, a growing concern for the health of urban residents increased interests in a variety of outdoor activities simply be done in terms of cost and time. They are specially interested in low-impact and safe exercises around residential or working area. Walking is the one of easily doing exercise in daytime or nighttime near residential area. The sidewalks of boulevard near the residential area is the best place for exercise because of easy access and the green space with roadside trees. However, if the nighttime is not guaranteed the proper lighting condition, the possibility of exposure to crime and the threat to pedestrian safety can be increased. Because roadside trees are one of the potential obstacle for lighting condition, supplementary lightings are important to mitigate interruption for safety. To meet such a need, the purpose of this study is to propose a simulation approach which improves lighting condition on sidewalks of boulevard with variety of roadside trees. To do so, the simulation approach is applied for analyzing the interrupted condition by classified five standard types of roadside trees considering the growth of them and finding optimal layout of supplementary luminaires by lighting types. The results of this approach shows that it is useful for assessing the safety of pedestrian in nighttime.

우리나라 요식업소의 작업 환경 및 급식되는 음식의 위생 상태를 위생 점검표 및 미생물 검사 결과를 기초로 분석, 평가한 결과는 다음과 같다. 1) 주방 및 객실의 위생 상태와 음식점 종사자의 위생 습관은 잠재적 위험성이 존재하는 불량 상태로 평가되어 요식업소 경영자와 종업원의 위생 개념에 대한 교육이 절실히 요구된다. 2) 음식에 대한 미생물 분석 결과, 요식업소의 업종 및 규모에 관계없이 탕류와 같은 높은 온도에서 조리되는 음식의 미생물적 품질은 비교적 좋았으나, 여러 단계의 생산 과정을 거치거나 실온에서 장시간 방치되는 음식 및 차게 급식되는 음식은 미생물적 품질이 낮게 나타났다. 3) 음식의 준비와 조리 과정에서 사용되는 기구 및 용기, 배선시 사용되는 식기의 위생 상태는 미생물 검사 결과, 매우 심각한 상태로 즉각적인 시정이 요구된다. 4) 식품 취급습관 및 주방의 위생환경, 음식의 조리 온도 등은 급식되는 음식의 위생 상태와 유의적인 상관 관계가 있는 것으로 나타났다.

Especially because of the distinctiveness that new experiments and research provoke coexistence of various risk factors, the researchers in university laboratory are being exposed to incidents that are difficult to predict. Due to the fact that the numbers of accidents that occur at the university laboratory are increasing, the necessity for laboratory safety management is on the rise. Most laboratory accidents are caused by the ability that can detect risk factors such as unsafe behavior or unsafe condition but is not working perfectly. In order to prevent researchers in advance from unsafe behavior or unsafe condition, effective safety education, systematic safety management, safe research environment, continuous safety check and proper measures after accident are the most important factors. In this study, survey was conducted in university laboratory to identify the factors that affect on safety management and to measure the safety management level. As a result, effective measures are proposed for the improvement of the safety management level.

Nowaday it is trend to be one cooling radiator and cooling fan from separate engine radiator and air condition radiator in cars. For the cooling fan is developed a electrical motor which is limited in size. The motor should be working in silence and have no electromagnetic Problem and high efficiency. In this paper will be proposed some parameters for improvement of the efficiency of a BLDC motor which is developed for the cooling system after theoretical and experimental investigation.

TDR(Tear Down & Redesign)means that renounce the past resolutely, from a white paper condition, let's change directions. That is, let's redesign from the basic of the establishment of the construction process. Through the switchover the conception, innovate totally the whole existing processes. TDR is the best core innovation activity. The ultimate aim of the TDR activity induces the employees to do more productive business and obtain excellent results in the future by solving the problems, which are the nonproductive business in the business process on the objective view, the business that customers don't recognize the value, the same old practice of business, and the unsettled business from the restriction of resources. By organizing the related to workers of those business, they can solve the problems for 3-4months by full time working This paper inquires what are the obstruction factors on the process of executing TDR activity. Through the search of the reformation plan for the improvement of immersion degree, it presents some methods to be successful business.

This study is to investigate the effects of cold forming method with steel sheet of SCP3C to improve continuous productivity. Experiments were carried out in various working conditions, such as the number of stamping and the punch temperature. The effects of the punch temperature and the number of stamping on drawability of steel sheet of SCP3C as well as clearance and draw-in in the number of stamping were examined and discussed. More improvement of continuous productivity in case of cold stamping rather than by conventional stamping at room temperature is obtained. The optimum forming condition for drawing trunk floor panel of SCP3C is shown as the punch is cooled by coolant of $-5^{\circ}C$ and at the same time both the die and the blankholder are heated by stamping and frictional heat.

Currently, there are two major problems in professional engineer(PE) licensure system in Korea to be accredited internationally. One is a incompleteness of system connecting the licensure and the accredited engineering education program and the other one is a insufficient working experience condition required for achieving PE license. Therefore, these two problems are setbacks hindering Korea's PE license accredited internationally. In this study, international tendency stream on mutual accreditation of PE license are reviewed first, and the PE licensure system of the major countries are compared and analyzed. Based on the results, requirements improvement plan are suggested and the gradual implementation method are suggested also.
