Currently, online means of replacing resident registration numbers(RRN) include I-Pin, mobile phone, credit card, MyPin, and general-purpose certificate. In order to issue alternative means based on the RRN, it must be designated through the designation review by the Korea Communications Commission(KCC) through a designation review by personal proofing agency and be subject to annual management. However, the criteria for designation and follow-up of the designation of the personal proofing agency carried out by KCC have been used in 2010 without revision, and there are problems that do not conform to the evaluation standards of various alternative means. Therefore, in this paper, we propose a method for improving the designation criteria and management system of the personal proofing service agency. The proposed method analyzes the characteristics of the alternative identification-based personal proofing service and proposes a follow-up management standard that can appropriately evaluate the analyzed characteristics and improves the designation criteria according to the emergence of new alternatives. Through the proposed method, it can be seen that it is possible to strengthen the safety of the personal proofing service based on the alternative means of RRN provided online and face-to-face and to protect the user's personal information.

When a building is planned and designed, the design should be able to minimize the cost during the whole life cycle of the building. This study has begun to analyze LCC about the alternative design which is applicable to renewable energy facility construction. It is reviewed domestic and foreign papers about the trend of LCC technology and it is determined the analytical method to analyze the LCC of renewable energy. Regarding the review of alternatives, it is chosen the three alternatives which are able to designed combing the renewable energy facilities and it is performed the LCC analysis about each alternative. Alternative 1 is Photovoltaic + Solar Thermal + Photovoltaic /Wind Power, Alternative 2 is Geothermal + Photovoltaic, and Alternative 3 is Photovoltaic + Solar Thermal. The LCC analysis is present value method, its analytical period is 40 years and it is applied 3.2% of real discount rate. As a result, it is proved that Alternative 1 and Alternative 3 are not able to collectible the early investment cost during the analytical period and Alternative 2 is analyzed that its pay-back period of early investment cost is about 31 years. As the final outcome of this study on case analysis, it is more advantageous to use the combination of Geothermal and Photovoltaic energy than to use the other combination in LCC aspect.

This study investigates market barriers in increasing the market share of Alternative Fuel Vehicles (AFVs). In particular, this study first conceptualizes the AFVs market model with the aid of generic system archetypes suggested by Wolstenholme. Among four generic system archetypes suggested by Wolstenholme, the market structure of AFVs can be explained by the 'relative achievement' archetype. Starting from the generic system archetype, this study extends the model boundary step by step to take account of various model assumptions necessary to simulate the model numerically. If there is a significant network effect on vehicle operating costs, it is difficult to achieve the shift to AFVs even in the long term without a policy intervention because the car market is locked into the current structure. There are several possible policy options to break the 'locked-in' structure of the car market, such as subsidies on vehicles, subsidies on fuels, and a niche management policy.

1. Outline of the Study A boom of baby hotels is taking place in Japan. Baby hotel means day care centers that renders services day and night for babies of working mothers. These baby hotels are thriving because many mothers welcome the system because of their needs. However, accidents occurred in a row recently and therefore baby hotel has suddenly become a social issue. According to the ministry of health welfare, there are 587 baby hotels in Japan accommodating about 10,000 children and they are mostly located around amusement centers. The reasons that these baby hotels thrive in spite of the fact that there are 22,000 day care centers in Japan are : (1) shortage of day care centers compared to the needs (2) most centers do not take in babies below 1 year. This study aims to describe the present status of the baby hotels and the background of the phenomena that made it possible for them to thrive with no permission from the government. This study mostly deals with the phenomena in Tokyo. 2. Day Care Policy in Japan and the Problems of Baby Hotels The present review deals with the problems from the following 6 dementions. (1) the shortage of day care centers (2) inadequate system for the care of babies (3) inadequate daily hours of day care centers (4) Unflexable enrollment system of day care centers (5) imperfect enfollment process & guidelines (6) lack of alternative institutions 3. Result The Ministry of Health & Welfare affered the following ways to cape with the problems of baby hotels : (1) restraint of the baby hotels (2) utilization of existing day care centers for the care of babies. In my opinion, these suggestions seem too superficial in solving the problems. I would rather suggest that the Japanese government review the whole system of child welfare administration. The Child welfare Law of Japan made a clear statement in its article 24 that, "if day care centers are not available, alternative institution for proper care of children must be sought for." My suggestions for the alternative care are : (1) public nursing rooms (2) family day care (3) extention of kindergarten hours (4) foster family care.

It is time to prepare the phaseout of R134a, the current refrigerant, in automotive air conditioning system because the EC deadline has been coming with new platform vehicles in 2011 and all vehicles by 2017. Until now a high-pressure carbon dioxide($CO_2$) system is the leading replacement of R134a in European auto-makers but there is no firm agreement in the world automotive market. Recently three new fluids have been announced as the possibilities from Honeywell, DuPont and INEOS Fluor. The new alternative refrigerant should meet the requirements like non flammable, non toxic, no ozone depletion effect and low GWP(under 150 to meet EC regulation). The objectives of this paper are to review the fluid H from Honeywell, the more possible alternative refrigerant in 3 new fluids, compare the properties of R134a & fluid H and see the possibility as a replacement of R134a. In this experimental paper we ran and reviewed the cooling performance data in the bench system, the vehicle and the field test. We found the possibility of fluid H system to meet the R134a system performance with some hardware modifications but agreed that it is still needed to study about the long term safety, environmental effects, material compatibilities and so on.

Traditional Manufacturing method is push system by plan made in advance and Japanese manufacturing method represented by JUST-IN-TIME is pull system which respond's to the demand flexibly. Both have their pros and cons. In general, it is well understood that push system is faster than pull system in the sense of manufacturing speed. However, pull system such as JIT excelles dramatically in the sense of work in process. Therefore, this paper is trying to put together to get alternative which has the advantage of both system. The objective of the paper is to enhance the effect of built-in manufacturing system without paying extra cost by way of introducing the alternative of the pull-push manufacturing strategic operational method.

In the approaching 21th century, the outstanding development in international sports has established arbitration as the preferred form of dispute resolution. Because the form of sports dispute becomes more complicated and varied with the quantitative increase of them, the reasonable and rapid settlement of them must be the important problem. The Alternative Dispute Resolution(ADR) as the settlement of sports dispute is regarded as the one of effective dispute resolution method and merits notice. The Korean Sports Arbitration Committee has been established for dispute resolution between athletes and the clubs or alike. Now, We must review and complements the rules of the Korean Sports Arbitration Committee in order to be a representative system of domestic sports dispute arbitration that settle the sports dispute practically and efficiently.
