본 연구는 유형별 공공임대주택의 주거환경을 최저주거기준과 세부 기준을 중심으로 ANOVA, 다항로지스틱모형을 활용하여 미시적으로 살펴보았다. 주요 실증분석의 결과는 다음과 같다. 첫 번째, 입주자뿐만 아니라 최저주거기준과 세부 기준은 공공임대주택 유형별로 특성의 차이를 확인할 수 있었다. 두 번째, 행복주택은 최저주거기준 미달비율과 설비기준을 제외한 나머지 세부 기준의 미달비율이 높아, 전반적인 주거환경이 가장 열악한 것으로 나타났다. 세 번째, 영구임대, 국민임대, 매입/전세임대 중 영구임대의 최저주거기준과 면적·방기준이 취약하였으며, 매입/전세임대는 구조·성능·환경기준의 미달비율이 높게 나타났다. 네 번째, 매입/전세임대가 다른 공공임대 유형보다 임대 불안감이 높았고, 특히 임대료상승과 보증금 미반환에 대한 불안이 높다는 것을 확인하였다. 이러한 결과를 바탕으로 공공임대주택 유형에 따른 맞춤형 지원을 통해 주거환경 개선을 위한 노력이 필요하다는 것을 확인하였다.

This paper deal with technique of tension length calculation for 350km/h high speed catenary system. Tension length affects in facility investment. Possibility of overlap increasing a tension length and the equipment investor decreases in order to decrease. Considers the parameter which specifies and the grudge which is possible long the fact that decides a tension length is the aim which is important plans overhead contact line. The element which decides a tension length with next following; (i) Operating range of tension device, (ii) Change of the horizontal tension which affects possibility of the effect which operates to the line and span, (iii) Tension of wire material the tensile force which is relation, (iv) Wire thermal expantion which relates with a standard temperature, (v) Curve radius, (vi) Wind velocity, (vii) Thermal range of overhead contact wire and mechanical design of tension mechanism etc.

This study is to suggest the proper standards of the pediatric facilities. We need to have the medical treatment standard focusing to the architectural concept because the living and medical treatment level and the demand of citizen is increasing. The way of research is mainly referring to USA's hospitals and the patients. This study is for the psychological stability of child. We found the form decisive elements and the basic form characteristic with analysing cases. This elements are emerging to the sociality, privacy, control, recognition and territoriality. We have to improve the satisfaction of the patient through this element. In the future, the role of the improved medical environment will have to be emphasized.

As a clean fuel, LNG or LPG is widely used in large restaurants or plants instead of coal. These fuels are easy to use and cheap. However, they are inflammable very much and easily exploded at the worst. So there are many laws and regulations legislated for the handling and usage of the gas facilities. Nevertheless, very harsh explosions occurred in several domestic or foreign places. In this paper a gas detection and alarm system was developed for large facilities. A new concept for connecting many gas detectors was proposed and based upon that a system including hardware and software have been developed and tested. Although up to 16 gas detectors apart 1 km from main controller can be connected currently, this system can be easily expanded for more detectors because each gas detector receiver communicates with main controller using industrial standard RS-485 multi drop technique. Furthermore several additive functions was included for the installation and maintenance convenience.

본 논문에서는 아파트에 시설띈 승강기의 운전실태블 분석하여 승강기 수용률을 설정하였다. 승강기 운전실태를 분석한 결과 승강기 동시운행률은 1년중 9월에 최대값을 나타내었으며 아파트(계단식,20층 기준)에서의 승강기 1일 평균 운행횟수눈 약 800회, 동시운행률의 최대값은 약 40-45%인 것으로 나타냈다. 송강기의 대수별 수용률은 현행 기준치보다 약 10%정도 낮은 것으로 분석되었다.

This study has performed the static loading tests for the composite train body of Korean tilting train. The structural tests based on the JIS E7105 standard were carried out in the test facility designed for the train carbody. The vertical, compressive and torsional loads were imposed on the underframe and the end structure of the carbody. the structural behavior of the carbody under the 3-point supporting and the natural frequency were evaluated as well. In addition, the test results were compared with the numerical one. From the tests. the structural strength of the hybrid composite carbody was assessed.

The objective of this study is to propose activation ways through an analysis on processing actual conditions and quality of farm food. For the analysis we have surveyed the actual condition of farms and conducted sensory test on farm food. Difficulties of farm business are in order to 'preparation of papers', 'facility standard', 'improvement of quality' and 'labeling'. Overall, products from major food companies achieved better results than farm foods in all sensory test. It is necessary to educate the 'Food Sanitation Act' and prepare a manual for the development of farm food.

It has been known that eater-side corrosion of fuel rods in nuclear reactor is accompanied with the metallic loss of wall thickness and hydrogen pickup in the fuel dadding tube. The fuel dad corrosion is one of the major factors to be controlled to maintain the fuel integrity during reactor operation. An oxide later thickness measuring device equipped with ECT probe system was developed by KAERI, and whose performance test was carried out in NDT(Non-destructive Test) hot-cell or PIE(Post Irradiation Examination) Facility. At first, the calibration/performance test was executed for the unirradiated standard specimen rod fabricated with several kinds of plastic thin films whose thickness ore predetermined, and the result of which showed a good precision within 10% of discrepancy. And then, hot test us peformed for the irradiated fuel rod selectively extracted from J44 fuel assembly discharged from Kori Unit-2. The data obtained with this device were compared with the metallographic result obtained from destructive examination in PIEF hot-cell on the same fuel rod to verify the validity of the measurement data.

Recently, many enterprises are introducing a workflow management system for the successful implementation of BPR(Business Process Reengineering). Proposed in this study is the workflow management system which has a light-weight component structure and an XPDL(XML Process Definition Language) file interpretation facility. The XPDL is the standard process definition exchange format developed by WfMC(Workflow Management Coalition). The major causes of inefficiency at current implementations of workflow management systems are the centralized workflow engine structure and the use of proprietary workflow definition format among most solutions. The proposed light-weight component structure in this study is the intermediate structure that takes the strength of both centralized and distributed workflow engines. And a prototype workflow system which uses an XPDL process definition file as input is developed through the thorough analysis of functional requirements.

The effects of the moments of the retrial time to the system performance measures such as blocking probability, mean and standard deviation of the number of customers in service facility and orbit are numerically investigated. The results reveal some performance measures related with the number of customers in orbit can be severely affected by the fourth or higher moments of retrial time.
