In this paper, a two-stage group sampling plan based on the time truncated life test is proposed for the Weibull distribution. The design parameters such as the number of groups and the acceptance number in each stage are determined by satisfying the producer's and consumer's risks simultaneously when the group size and the test duration are specified. The acceptable reliability level is expressed by the ratio of the true mean life to the specified life. It was demonstrated from the comparison with single-stage group sampling plans that the proposed plan can reduce the average sample number or improve the operating characteristics.

In case of earth-covered storage, the condensation occurs on surface of wall and stores in summer with high humidity because of low temperature of constructional mass. Therefore, the preventive plans should be considered to protect stores from the damage by corrosion in earth-covered storages. This study aims to suggest the methods of forced ventilation by the air, to solve the problems of construction's surface condensation at the Magazine of igloo type which is similar to earth-covered storages. A fan was installed at the air outlet for exhaust gas to conduct forced ventilation. The surface and indoor temperature were measured, and then the influence of those on condensation was analyzed. The results of this research are follows; 1) Forced ventilation by a fan affects the rise in surface temperature of walls and stores. 2) The condensation on surface of walls and stores was reduced after operating a fan.

Seoul Metro is celebrating 32 anniversary this year and through developments over the years it is being evaluated as the 3rd in the world in operational sizes, the 4th in the world in facility sizes, it transports about 4 million passengers per day and it is now a vital public transportation means. However, the track maintenance organization and manpower structures along with technology cooperative office were led by unions that do not like changes and overshadows the trends of changes by expanding organizations and recruiting personnels and it is going against the current of times. Thus, it is time when a break point is required for breaking away from labor-intensive methods of the past that rely on hand works and vertical organizational structures. Therefore, this study investigates the states of national.international track maintenance operations and examines and analyzes the problems so that it can be utilized as base data for efficiently operating the organizations and maintenance works on track fields.

Fuel cell with high electric efficiency has many probabilities of commercial use. Especially, polymer electrolyte or proton exchange membrane fuel cell (PEMFC) which is a low operating temperature and has less influence on $CO_2$ concentration is considered the power generation system of small building and household. We calculated the optimal operational plans of 1 kW household PEMFC power system based on daily electric and heat demand patterns of various size of apartments. Calculated results show that the economic feasibility of PEMFC power system is very sensitive to the cost policy of electricity and natural gas.

Generally, there are laser operating equipments( aligner, stepper) and electronic microscope( SEM, TEM) as a high precision manufacturing and inspection equipment in semiconductor production companies, precision examination and measuring laboratories. Mostly, these equipments are characterized by projection and target part. The relative displacements between projection and target part are dominant roles in vibrational problem in these precision equipments. These relative displacements are determined by the position of incoming vibration and the difference of vibration response in projection and target part. In this study, the allowable vibrational limits are suggested and the vibrational reduction plans are proposed by measurement and analysis of vibration phenomenon in the Clean Room in PDP(plasma display panel) production building. The vibration performance is evaluated by comparison relative displacements between projection and target part before/after the vibration isolation plan.

Purpose The purpose of this study is to introduce U-CAAM(University-Competence Assessment & Accreditation Management) system which is designed to effectively manage extracurricular education programs in a university. Extracurricular education is known to be very important to increase core competences of students who have different levels of knowledge and skills as well as career plans. Design/methodology/approach In this study, U-CAAM system which is designed and developed to tackle the problems related to university extracurricular education is introduced. The case will give meaningful insights to those universities which consider to have similar environment. The survey is conducted to show the need to a systematic management environment to effectively manage the problems with operating extracurricular education programs. Findings The survey result shows that universities understand the need to manage extracurricular education programs effectively. Implementation of U-CAAM provides the practical insights related to this issue.

There are a lot of different types of noise from construction site and it depends on construction stage, equipment type and number of operating equipments. The problem is almost noise from construction site is high level and some kinds of noise levels are over 100dB. In addition, if construction site is located in downtown, there are a few options to reduce noise level. Therefore several site mitigation plans are developed to reduce different types of construction noises and it is applied in site and evaluated noise reduction performance in this study.

Periodic safety review on Kori Unit 1 has been successfully done for the first time in Korea. 11 safety factors of the review were fully evaluated in accordance with the domestic legal system. Although it is the oldest nuclear power plant in Korea, Kori Unit 1 was found to have maintained good operating conditions and continuously enhanced its safety by implementing post-TMI action plans and other safety issues, such as replacing steam generators and process/control system. It can be therefore confirmed that safe operation of Kori Unit 1 is guaranteed until next periodic safety review. Nevertheless, some corrective action items were recommended to enhance further its safety level, such as equipment qualification, additional ageing management program, strengthening of some procedures related to administration and human factor. The results of PSR can be utilized for the continued operation beyond the design life as long as the plant safety is maintained and improved. Experiences of the PSR on Kori Unit 1 can be also applied to PSR on other plants.
