This study was performed to develop a children's dietary life safety index required by the Special Act on Safety Management of Children's Dietary Life enacted in 2009. An analytical hierarchy process was used to obtain initial weights of dietary life safety evaluation indicators. The Delphi method was applied to develop the weights along with 98 food and nutrition professionals. Three representative policy indicators, nine strategy indicators, 11 main evaluation indicators, and 20 detailed evaluation indicators were selected for the children's dietary life safety assessment. Three policy indicators and nine strategy indicators were the following: children's food safety indicator (support level of children' safety, safety management level of children's favorite foods, and safety management level of institutional food service), children's nutrition safety indicator (management level of missing meals and obesity, nutrition management level of children's favorite foods, and nutrition management level of institutional food service), and children's perception and practice level indicator ("Dietary Life Law" perception level, perception, and practice level for dietary life safety management, perception, and practice level for nutrition management). Weights of 40%, 40%, and 20% were given for the three representative policy indicators. The relative importance of nine strategic indicators, which were determined by the Delphi method is as follows: For children’s food safety, support level of children's safety, safety management level of children's favorite foods, and safety management level of institutional food service were given weights of 12%, 9%, and 19%, respectively. For children's nutrition safety, the missing meals and obesity management level, nutrition management level of children's favorite foods, and the nutrition management level of institutional food service were given weights of 13%, 11%, and 16%, respectively. The "Dietary Life Law" perception level, perception and practice level of dietary life safety management, and perception and practice level of nutrition management were given weights of 4%, 7%, and 9%, respectively.

The building needs of the community are met by the interrelated construction activities of maintaining, modernizing and replacing the existing stock of building and by the erection of additional new building. Studying the service lift of buildings and how it is determined can serve as an important measuring stick in making decisions on construction policy. Therefore, the purpose of this study is to provide useful information for future construction through a comparative and analytical study of building structures on disappeared buildings. It was found that most building structure had a shorter service life than the standard set by The Korea Appraisal Board. This situation may have occurred due to the sharp rise in replacement of older buildings with new buildings for the purpose of monetary profit. To increase the economic life of buildings reduce losses of the nation's capital henceforth, examination on policy md steady study needs to be done.

In order to ensure the construction of sustainable reinforced concrete structures, durability evaluation of RC structures before construction should be carried out. In this paper, a service life evaluation technique using a safety factor determined by a reliability theory for RC structures subjected to chloride attack is proposed. The life safety factor and the service life evaluation .proposed in this paper can be applied consistently for the durability evaluation of recently developed Korean standard specification for durability of concrete structures which be used effectively for the evaluation before construction and maintenance for RC structures under chloride attack.

The purpose of this study is to identify the cognitive measurement scale of residential life management of apartment residents. The questionaires were distributed to 550 housewives and 392 questionaires were analyzed in this study. For the construct validity of this residential life management, the methods of factor analysis was used. As the results, 5 factors of residential life management of apartment residents were extracted. They are 1) Residential life covenience service, 2) Residential life support service, 3) Resident's activity support and announcement of managerial works. 4) Safety and order sustaining, 5) Precaution to accident.

In urban life, an interest in safety and demands for safety information about crimes and traffic are increasing. As well, communication on the internet is so active. In this study, we analyze web sites in US, UK, and JP, which have started safety map services, and then we provide basic material for the introduction of safety map into Korea. According to the analysis result, in US and UK, the safety map web sites are administered by the government and provided to the general public. The geographical area is provided around administrative districts and statistical data. In JP, The safety map web site provide not a one sided service but the service that user can directly take a part in, and also there is an web site for crimes against vulnerable people.

The purpose of this study was to analyze the factors of residential life management of apartment house, and to examine the tendency of demands and satisfaction according to the resident's characteristics. As the result, 5 factors of residential life management of apartment house were extracted. They are I. Residential life accommodation service, II. Residential life support service, III. Resident's activety support and announcement of management works. IV. Safety and order mainteanance, V. Precaution to accident.

The special organization that our military service is conscripted by the duty of national defense purposes to the period of military service. So couple of soldiers are think as the corresponds to college, or some knowledge layer from the operating management discarding period, lifetime value. But, now a day changed of the military life, it is when the individual soldiers can have some self-development and the lifelong education in terms of a period, and can changeing the footsteps of the new life that the function as a 'bridge' to activate production of barracks life. So that it can be supported themselves need to strive for human resource development. This study is being discussed on the correlation of military human resources and qualified operating and sustainable and promising future eligibility for qualified by taking advantage of the Boston Consulting Group Matrix(Boston Consulting Group Matrix).

This research studies on the demand forecasting for service parts considering parts life cycle, that gets relatively less attentions in the field of forecasting. Our goal is to develop forecasting method robust across many situations, not necessarily optimal for a limited number of specific situations. For this purpose, we first extensively analyze the drawbacks of the existing forecasting methods, then we propose the new demand forecasting method by using these findings and reinforcement leaning technique. Using simulation experiments, we proved that the proposed forecasting method is better than the existing methods under various experimental environments.

In this paper, service life for RC(Reinforced Concrete) substructure subjective to carbonation was evaluated through deterministic and probabilistic method considering field investigation data and Design Code(KDS 14 20 40). Furthermore changes in service life with increasing COV(Coefficient of Variation) and equivalent safety index meeting the same service life were studied. From the investigation, the mean and its COV of cover depth were evaluated to 70.0 ~ 90.0 mm and 0.2, respectively. With intended failure probability of 10.0 % and 70 mm of cover depth, service life decreased to 137 years, 123 years, and 91 years with increasing COV of 0.05, 0.1, and 0.2, respectively. In the case of 80 mm of cover depth, it changes to 179 years, 161 years, and 120 years with increasing COV. The equivalent safety index meeting the same service life from deterministic method showed 1.66 ~ 3.43 for 70 mm of cover depth and 1.61 ~ 3.24 for 80 mm of cover depth, respectively. The various design parameters covering local environment and quality condition in deterministic method yields a considerable difference of service life, so that determination of design parameters are required for exposure conditions and parameter variation.
