Objective: The purposes of this study are to investigate ergonomic problems and to propose their improving measures in office environment of big general hospitals. Background: Office tasks have varying risk factors of work-related musculoskeletal disorders (WMSDs). The first symptom resulted from the office work was recognized as an occupational disease in Korea in 1986. Although the symptoms have increased since its first recognition, there has been few study on the effect of office work environment settings. Method: First, the author took pictures of working scenes performed in three big university hospitals. Next, the pictures were analyzed in view point of ergonomics. Based on the analysis, their improving measures were proposed for reducing work stress. Results: The results showed that most physical office environment settings such as dimensions of tables/desks and chairs, leg room, thigh, knee and foot clearances, and chairs used did not satisfy the ergonomically recommended design guidelines. In addition, some clerks placed personal belongings under their desks, put monitors in high position and did not lean against the backrest of chairs in seated tasks, which resulted in poor working postures of leg, back, neck etc. It is recommended that the hospital management should provide their clerks with ergonomically designed office furniture and continuously perform ergonomics training program for raising clerks' recognition for office ergonomics. Conclusion: Most office environment settings investigated in this study were not in good condition in view point of ergonomic design for the settings. Application: It would be useful as basic data for establishing ergonomically good office environment in hospitals.

The interior noise reduction of construction equipment is concerned for improving the driver comfort in this study. From the baseline test, the exhaust noise gives a big contribution to the interior noise of construction equipment. And the detail noise contribution analysis of the exhaust system, the tail pipe, which is for ventilation an engine room hot air to outside, amplify the exhaust noise around operating engine RPM associated with tail pipe structural and cavity resonances. To remove the noise amplifying effects, the tail pipe has to be shorted its length. Even the noise can be attenuated the ventilation flux when using the redesigned tail pipe is reduced than the original one. Thus, a shape change of the tail pipe is additionally needed for increasing the ventilation flux and attenuating the exhaust noise using CFD technique. The CFD results of the tail pipe give a meaning full information what obstructs the ventilation flex in the current design and how changes the tail pipe.

The global demand for Liquefied Natural Gas(LNG) continues to increase and is facing a big cycle. To keep pace with the increase in international demand for LNG, the demand for LNG fueled ships is also increasing. Since LNG fuel tanks are operated in a cryogenic environment, insulation technology is very important, and although there are various types of insulation applied to Type C tanks, multi-layer insulation and vacuum insulation are typically applied. Powder insulation materials are widely used for storage and transportation of cryogenic liquids in tanks with such a complex insulation structure. In this study, compression tests at room and cryogenic temperature were performed on closed perlite, glass bubble, and fumed silica, which are representative powder insulation material candidates. Finally, the applicability to the Type C fuel tank was reviewed by analyzing the experimental results of this study.

본 연구의 목적은 대학교 급식의 외부 음식점 도입에 대한 필요성을 제시하기 위한 기초 자료 확보를 목적으로 하고 있으며, 이를 위해 대학생의 학교 급식 이용 행태 및 욕구를 파악하여 제시하여 시장에 필요한 상품과 학교 급식의 경영의 합리화를 위한 기초 자료를 확보하고자 한다. 학교 급식의 혁신적인 이미지 전략의 일환으로 외부 음식점 도입을 선택할 수 있는데 학생들이 패스트푸드를 선호 하는 이유는 음식이 빠르게 서빙된다는 잇점과 가격이 저렴하다는 잇점을 들고 있다. 즉, 현재 시행되고 있는 학교 급식에 대한 불만으로 도출되는 것은 맛의 저하와 가격의 상승, 서비스의 저하 현상을 이유로 살펴볼 수 있다. 학교 급식의 질은 외부 음식점에 비해 학교 급식의 가격대의 만족도를 평가한 결과 학교 급식의 질은 낮게 평가되었으며, 외부 음식점의 가격이 높다고 평가되었다. 외부 음식점 도입시 선호하는 음식의 조율에 따라 평균값을 분석한 결과, 한식류나 햄버거를 희망하는 집단이 학교 급식의 질적인 수준을 낮게 평가하고 있는 것으로 나타나 학교 급식의 질적인 향상이 시급히 요구되고 있다. 따라서 학교 급식의 발전 방안으로 외부 음식점의 도입의 필요성도 제기되며, 학교 급식 이미지의 강화와 질적인 향상이 필요하리라 보며, 가격 수준의 적절한 배치도 함께 이루어져야 한다.

This paper aims to identify the characteristics and the current situation of the architectural characteristics, children's characters using facilities, and status of management and utilization by surveying 'Day Service for Children' in Tokyo-do. First, About the status of management and utilization, 'Day Service for Children' is operated by a local government, NPO corporate group and social welfare corporate. There are not big differences of the care program or running hours depending on operating principals but there are differences depending on staff organization, number of children and space constitution. Also, infants ratio at 'Day Service for Children' is high for the purpose of detecting disability early and supporting their development early. They have diverse disabilities but developmental disabilities' ratios high and most children are using both this facility and normal nursery centers together. Samples for proper child care based on status of space constitutions were installing lock, raising door knobs and using softer floor materials which are for children's safety. For the problem of space utilization, most comments were about lack of space which is not enough for teaching and training materials. Therefore, as an example, observation rooms for parents and teachers were sometimes used as storages and it changes teachers' moving direction, staying area and behavior zone. The programs of 'Day Service for Children' are divided to group teaching and private one. It will be the best if they have separate spaces such as group class room, private class room and play room. When they were operated by NPO corporate group or Social welfare corporate, there are many cases that their space was not properly zoned for each activity.
