Decreasing actual greenhouse gas will be difficult if it is not solved addressed in architectural fields. Zero emission building or zero energy building, maximize the efficiency of energy, which means the building can operate by their own renewable energy facility without any other supplying. To be a zero emission building, a building needs realization of high efficiency low energy consumption, construction of building its own energy production facilities and lastly a power grid connection. According to increasing of DC load about TV, LED lighting, computer, IT in building for living and business, it is expected the save of energy when the system of AC power distribution change into the system of DC power distribution. Renewable energy exists a big different rate produced by outside environment. When electrical power overproduce, it can supply for system. Otherwise, if electrical power produce less, it can receive supply from system. Send and receive power can lead to zero to annual standard. This paper shows the simulation about efficient control of power conversion which is related to DC power distribution of architecture and DC output of renewable energy by using L-type converter.

As the rapid growth of Industrial society, many enterprises are inclined to ppm management from the traditional$3\'{o}$ management method. Therefore it is need to extend process capability index for guarantee of quality assurance level to ppm unit. Thus, in this paper, using the probability of standard normal distribution from $ 3\'{o}; to; 6\'{o}$ which was developed by Song(1997), the capability index which is proposed considers the numbers of inspection facility and quality assurance level. Also, quality assurance level is determined by considering the precision of inspection when one and two sided specification limits are given for the probability which is out of the specification limit.

We need to do the supervision work is necessary to prepare detailed criteria in order to pursue the electronic power facility's quality, prevention of poor construction, electric safety, and the qualitative improvement of electronic technology. The detail standard has need of legalization for systematic and efficiently achievement at the field of construction work. In such respect, this paper will examine a lump improvement of supervision works and prevention of poor construction by arranging the necessity of constructive supervision accomplishment guide notice and the establish plan for rationalization of supervision works.

Recent year, the vibration induced fatigue and noise of piping work become critical in offshore hydrocarbon production facilities with increasing requests by major oil company. In this paper, the risk base piping vibration induced fatigue assessment of NORSOK L-002 standard and UK Energy Institute guideline have been introduced with real project application practice. Also the piping breakout noise evaluation by flow restriction devices of compressible and in-compressible flow are reviewed with its practical application on real project.

The purpose of this study was to assess the needs of education program and to analyze importance of education courses for school food service cooks. The questionnaires were developed by reviewing literatures on education programs for cooks and by interviewing with cooks who are working in school food service. A total of 150 questionnaires were surveyed at Kyonggi University and 90 of them were analyzed. The cooks in school food service wanted to take continuing education program about cooking skills and school food service operation skills. They wanted to take a culinary courses for 10 days and they wanted to take a food service operation courses for a week. The school food service cooks emphasized on courses of job analysis, laws and regulation, food sanitation, standard recipe, safety, equipment, and facility and layout. And they thought not only Korean food but also western food, Chinese food and Japanese food are important.

This study is intended to understand the architectural characteristics and trends of general hospitals in Europe. The Observations, interviewes with the staff, and analyses of related materials were executed through the study-visits of sample hospitals. Some results of the study could be summarized as follows : (1) The architectural characteristics of sample hospitals could be described as the realization of horizontal design concept, application of urban design method, specialization of service departments, intergration of facility design, and planning for the emergency & disaster. (2) The architectural trends of sample hospitals could be suggested as the decentralization of functions, promotion of building standard, enhancement of interior space, consideration of environment, and autonomous management & operation of facilities. (3) The humanistic and environmental approaches from european hospitals would be preferably applicable rather than the popular concept of automation, ultra-modernization and mega-structure in Korea. First of all, the bed-center and proper facilities for disaster should be considered.

Opening commercial service of KTX at the time of demanding more flexible train set for HONAM line and JEONLA line, it's necessary for the Korean High speed train, performing the stabilization; to modify the design in aspect of passenger and maintenance. In order to ensure the optimized interior design in Korean High speed train, it is necessary to review the major items such as disabled passenger facility, toilet, seat arrangement, compartment partition and door, access door, electrical cabinet, color and paint through the European standard and compare with other high speed train.

In this study, evaluation of physical and chemical properties of crushed sand was performed to establish optimal mix proportion standard for concrete using crushed sand afterward. Most of properties of crushed sand were satisfied with KS F 2527. Especially, chemical stabilities such as alkali-aggregate reaction were fairly good. However, considerable attention would be required in using crushed sand from lime stone judging from the result that weight loss of it was more than 23.8%. There were some differences in the properties with production region, stone type and capacity of facility, therefore it is thought that quality should be controled by optimal regulations for corresponding items.

Safety requirment or guidance have been developing for a long time in the UIC, Germany, France, and Japan etc. Also, In Korea, the Ministry Construction & Transportation make an progress about this issue, document, called 'railroad tunnel safety standards 6th draft', was developed. In this paper, we'll show standard of other country and compare with Korea draft. next, we'll show some kind of railroad safety facility and installations and explain a relationship of safety issue and standards

The energy efficiency and environment-friendly aspect of the railway system would be superior to other on-land transportation systems. In a preliminary feasibility study stage, the energy efficiency and problems related with environment are usually not considered. Selection of optimal railway line is taken into consideration include of the purpose of railway, geographical features and facility of management. The railway Alignment which could be reasons of environmental problems are focused and studied in this paper. This study performed opinions of specialists, checking of industrial environment, analysis of bid guideline to select the optimal line and executed AHP method to make quality model and choose weight factors. The investment for railway systems could be encouraged by the considering of main environmental elements evaluated with the modified noise and vibration standard for environment-friendly railway construction.
