Purpose: Apartment housing should conduct a cyclic repair to keep and maintain the building performance since they are constructed. Therefore, the repair plan would be provided for long term period which explains the repair time, items and repair cost. Residents of apartment housing are responsible to pay for the repair activities. For repair cost, residents would reserve the money for repair little by little continuously until the required repair time because the repair cost takes a big burden for residents and lots of money a time. But, there is no systematic approach to provide the long term repair cost because it is no proper forecast of the repair cost to the upcoming repair time. In this study, it aimed at providing the monthly accumulation of the long term repair cost with the survey data in Seoul. Method: For these, the surveyed data are classified into 6 categories and number of data are 1,918. In addition, it developed the repair cost model for the 24 repair works and the cumulation function which is reflected with the each cost model. Result: This study are shown as follows : First, among the various estimation for the repair cost, the power function has a goodness of fit in statistics. Second, the monthly accumulation would be 12,840 won/household in size of $100,000m^2$ management area and $81.7won/m^2$ in size of the 1,000 household number during 40 years.

In a recent survey conducted among Seoul citizens, the demand for crime prevention in addition to settlement of environmental problem and traffic system improvement turned out to be the highest. In particular, the demand for prevention of crimes in residential areas was higher than any other items. The crime rates are especially high in deteriorated residential districts, which indicates the relation between crimes and physical environmental factors. In other words, proper measures for surroundings can prevent crimes. While there may be various ways to keep the residents from crimes safely, CPTED, a crime preventive method in a way of improving the physical surroundings is one of the most noteworthy solutions. The principles of CPTED involves the basic principles such as Natural Surveillance, access control, and securing of territoriality and additional principles of strengthening of Activity Support and Maintenance & Management.

This is a basic study of the remaining armors and helmets of the Joseon period for our better understanding and better maintenance of them. For the purpose, this paper shall try to show the present situations of the remaining armor and helmets of the period in Korea, and their typical classification for periodization, and the nomenclature about them. First, to oversee the present situations of the remaining armor and helmets of the period, study was done about the kinds of armors and helmets, their users, and their possessors today. It was found that the exact dates and users were unclear for many cases of the armors and helmets under our consideration. It is understandable when we consider many of them were exported to foreign countries, instead of being well-preserved in Korea upon excavations. Secondly, for their typical classifications for periodization, types were delineated from the pictures and drawings in reference to the periodical changes of them from Korean historical records. The result was that we can find out 4 types of armors, and 3 types of helmets, with their combinations. This shall be usefully applied for the better periodization of the remaining items. Thirdly, we come to the problem of naming of the remaining armors and helmets. For better nomenclature of the remains all the names of the armors and helmets for the Joseon period are collected from historical literature, to figure out some principles of nomenclature for them. I found some discrepancies with the present names of them, and my propositions are suggested to replace them.

With the emergence of indirect procurement, it has become a global trend for companies to outsource their maintenance, repair, and operating (MRO) supplies to procurement service providers (PSPs). Due to the variety of MRO items, evaluation of numerous suppliers in various industries is a particularly complex task for PSPs. Due to this complexity, many PSPs still evaluate and select suppliers based on the sourcing managers' subjective knowledge. Through the case of adopting a supplier evaluation system, this research is to find the managerial issues organizations should consider when they transform sourcing managers' knowledge into the system. We interpret the issues based on the Technology-Organization-Environment (TOE) framework. This case conclusively shows the importance of positive feedback loop between the users and the information system for the performance improvement of the system.

Energy use has been recognized worldwide as a main cause of global warming and it is at the center of climate change. In this study, problems and measures of zero-energy building construction are investigated and analyzed. Based on the results, evaluation criteria of the zero-energy building are suggested. Performance related factors(Q) representing the environmental grade were divided into three categories as outdoor, indoor environment and maintenance. Energy related factors(LR) representing the energy load were divided into an energy, materials & resources, water cycle management, land use and transportation. Detailed fifty three items are listed for the evaluation under the consideration of energy, water cycle management sections gave weight. Upon receiving the first in the environment friendly certification system, Seoul Central Post Office and Seoul Metropolitan Water Supply Center evaluated. The reason why this score difference is due to lack of use of new generation energy building construction is required expensive costs so need expansion of governmental support. This effort is successful zero energy building construction and copes with global warming and climate change.

Tributary is a part of life space for people and a very important place that accommodates rest recreation and other daily activities. absolutely insufficient basic data about water quality and flow rate are available for basin management. Efficient water and basin management systems, which are also supported by local residents can be established by securing such basic data of major tributaries in the Nakdong river system. In this study, the fluctuation characteristics of upstream and downstream water pollution levels were compared using the measurement results of the water environment measurement network and the tributary monitoring project for the gyeseong-stream and Hwapo-stream in the Nakdong-miryang watershed. In 2017, when water pollution is the highest, it was confirmed that the annual average rainfall was the lowest. Although the upstream and downstream water quality tendencies of the Gyeseong-stream are similar, the water quality concentrations of the Gyeseong-stream are relatively different. But although the Hwapo stream has various causes of pollution, there was not much difference in the level of pollution between the upper and lower streams. In addition, both rivers need the ability to purify rivers by securing sufficient water for river maintenance, and if the correlation between water quality items can be inferred through continuous monitoring of tributaries where the aspect of water quality change is unclear, water quality management Determined to be efficient operation.
