The current housing performance rating system displays the performance rating of the houses supplied by the housing construction company, approved by the Housing Law. This system is intended to provide accurate information to the consumers in the announcement of the tenant recruitment, thereby improving the quality of the housing. This system was revised in January 2005 and implemented from January 2006. It is obligatory for companies with a scale of more than 1,000 households (energy performance rating is over 300 households), but there is currently no content on the waterproofing field. Therefore, this study suggests the revision plan proposes the necessity of the inclusion of the performance grade for the waterproofing field which is not currently implemented in the apartment house performance rating system, and to understand how to secure an adequate living environment. As a result, according to survey results, the performance score based on the difficulty of the maintenance method according to future leaks was selected and the revised system was prepared. Based on this, the performance grade for the virtual apartment was evaluated, and the results show that the performance of various grades is presented accordingly.

As data management and analysis technology advances, there is active discussion on how to utilize data generated in construction projects. Among them, the materials produced during the supervision work are highly useful because their generation cycle and format are regulated according to relevant laws. In this study, we analyzed whether the data produced during the supervision work in the construction phase of apartment housing can be utilized for project performance management. First, this study identified key data necessary for performance management through FGI with experts in the field of apartment housing. Next, we collected supervisory data from the case project and identified whether the data was generated, its cycle, and storage format. As a result of the analysis, the supervisory data contained various information that could measure the performance of construction projects and had the advantage of standardized data. In the future, utilizing supervisory data is expected to enable effective performance management of apartment housing construction projects.

국내에서는 최근 빈번한 사고를 유발하는 지하시설물의 안전확보 및 효율적 유지관리를 위해 공동구를 포함한 지하시설물을 중점관리 대상 시설로 선정하고 「시설물의 안전 및 유지관리에 관한 특별법」을 개정하여 성능중심의 유지관리체계를 도입하였다. 성능 중심의 유지관리체계는 사용 중인 시설물의 기능을 유지하기 위하여 요구되는 시설물의 안전·내구·사용성능을 종합적으로 평가하고 그에 따라 유지관리계획을 수립하는 것이다. 그러나 현행 공동구 유지관리체계는 안전성 위주의 평가방식으로 관리되고 있어 내구·사용성능이 고려된 종합성능평가를 실시하는 데에는 한계가 있다. 이에 본 연구에서는 델파이 기법을 활용하여 공동구에 대한 안전·내구·사용성능 항목을 선정하고 엔트로피 가중치 기법을 통해 각 항목들에 대한 가중치를 산정하였다. 향후 공동구 성능평가 시 본 연구에서 도출된 연구결과를 활용한다면 유지관리계획 수립 시 합리적인 의사결정을 지원할 수 있을 것으로 기대된다.

Different housing systems have considerable influence on performance in poultry production. Therefore, the present study was undertaken to investigate the impact of different housing systems on the performance, bone mineral density and egg yolk fatty acid composition in laying hen. Hy-line brown pullets (n=450) of 12 weeks age were randomly divided into 3 housing systems with 6 replicates of 25 birds in each room. A diet with 2,750 kcal/kg ME and 16.5% CP was assigned to all birds. The pullets provided free access to feed and water. Significantly (P<0.05) higher values for egg production, egg mass and feed conversion efficiency were found in battery cages, however egg weight, egg shell color and breaking strength was remarkably (P<0.05) higher in floor system. The albumin height and Haugh unit were significantly higher (P<0.05) in battery cages which was statistically similar to aviary housing system. The egg yolk fatty acids concentration of linoleic acid and linolenic acids were significantly higher in aviary and in floor system, respectively, however both values were lower in battery cages. Saturated and unsaturated fatty acid content (%) in egg yolk did not influence by any housing systems. Bone mineral density was significantly higher (P<0.05) in floor and aviary housing system than that of battery cage system. It was concluded that in battery cages the egg production and composition maximized, however higher bone mineral density and yolk fatty acids content can be improved in the laying hen reared on floor and aviary housing systems.

The purpose of this study is to suggest basic data for elderly housing design to be considered elder's characteristics. A survey carried out for 110 respondents with face to face interview visiting each house between May and June, 1999 with modified and drawn questionnaire from analysis of preparatory investigation data. The questionnaire was composed of the general characteristics of respondents, general characteristics of housing, residents' satisfaction with the use of housing space, performance degree of the elder's daily activities. To analyze the data of 106 cases, frequency, percentage, mean, standard deviations, one-way ANOVA, reliability analysis and Scheffe test were used by running SPSSWIN program. The results on the housing satisfaction and performance of activities in daily life of elderly in the detached house were as follows.: In this survey, the elderly had high value in satisfaction with the size of current house as the mean 3.14 points, but they were dissatisfied with the rising of house as the mean 2.82 points. The satisfaction with living room space was the highest but the satisfaction with toilet space was lower than others. Among the activities of daily life in housing space, housing related activity was the hardest to perform as the mean of 3.15 points. In consequence, consideration on and interest in the planning of residential spaces are needed so that the elderly can perform the action of housing life effectively and efficiently.

This paper investigated how Fine Fly Ash (FFA) with $14,000\;cm^2/g$ of Fineness affects the micro structure and material properties of High-Performance Concrete (HPC) before and after hardening from Material Test of HPC and Cement Paste. FFA is applied as a substitute of Silica Fume which is used necessarily in producing HPC. As a Material Test results, 5% FFA series specimen shows the lower fluidity than SF series specimen. When, however, the Fluidity of 10% FFA series specimen is increased reversely to the similar value of SF series specimen. The Porosity of FFA series specimen of 3 day age is displayed to $21{\sim}24%$, which is higher than $19{\sim}20%$ porosity of SF series specimen, while that of 28 day age is reached to $8{\sim}9%$, which is improved compared with 10% fo SF series specimen. It can be thought that FFA has better influence on the porosity of HPC in case of long term age. The Compressive strength of FFA series specimen shows the similar result with the property of porosity. The compressive strength of 28 day age FFA series specimen is $98{\sim}106%$ of SF series specimen and 107% of plain specimen to reveal better strength development.
