In recent years, IT companies offer various cloud services using hardware-based technologies or software-based technologies. User can access these cloud services without the constraints of location or devices. The technologies are virtualization, provisioning, and big data processing. However, security incidents are constantly occurring even with these techniques. Thus, many companies build and operate private cloud service to prevent the leak of critical data. If virtual environment are different according to user permission, many system are needed, and user should login several virtual system to execute an program. In this paper, I suggest the access control method for application software on virtual operating system using the Open Authentication protocol in the Cloud system.

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.

Due to the increasing needs of land supply, green space has been continuously encroached and resulted considerable naturality deterioration in Korea. In order to overcome the problem, it is necessary to introduce a integrated system for managing the quantitative and qualitative aspects of green space. With this regard, this study is to derive the feasibility for the adoption of the 'no net loss of green' policy to Korea from German and Japanese experiences. In Germany, natural resources are protected and inevitable damages were compensated through the adoption of 'interference regulation'. In Japanese case, future green space and artificial green foundation should be specified on the green basic plan which pursuit the improvement of naturality. In order to introduce the 'no net loss of green' policy to Korea, not only awareness raising on integrated green management system but also amendment of related regulations are needed. In detail, restoration and recovery on the damaged nature should be clearly elucidated and indicators to evaluate the current naturality and calculation methods for the restoration should be developed. Should this integrated green management system introduced, deterioration of naturality by development activities could be minimized thorough the adoption of land development permission criteria and green space management methodologies.

In this study, the constitutional basis of public concept of land and concept of development gains are confirmed, and justification of the development charges system through the precedent of the Constitutional Court is investigated, and suggestions for improvement of fairness and reliability of development charges calculation are proposed. First, it is necessary to develop a system for estimating the development charges for securing transparency of the development charges system, preventing speculative development projects, and streamlining administrative efficiency. Second, it is necessary to prevent bad calculation by institutionalizing the responsibilities of experts to construct specification of the development cost calculation sheet submitted by taxpayers. Third, in order to precisely calculate the development cost, basic data should be specified in conditions for approval from the time of granting permission, or it should be minutely described in development charge treatment regulations.

The importance of data as a core resource of the 4th industrial revolution is emerging, and companies illegally collect and use personal data. In the financial sector, active research is conducted to safely manage personal data and provide better services using blockchain, big data, and AI technology. In this paper, we propose a system that can safely manage personal data by using blockchain technology, which can be used without changing the existing system. The composition of this system consists of a blockchain, blockchain linkages, a service provider, and a user (i.e., an app). Blockchain can be used regardless of its type and form, and services are provided by classifying blockchains and services in the blockchain linkages. Service providers can access personal data only after requesting and receiving delegated permission from users. Existent MyData services store all data in a user's mobile phone, so information may get leaked due to jailbreaks or rooting. But in the proposed system, personal data are stored in blockchain so information leakage can be prevented. In the future, we will study ways to provide customized services using personal data stored in blockchain.

This study examines the critical features of 'Library Law' introducing the public library registration system. Accordingly, we conducted a document analysis to explore the legal meaning of registration in the 'Library Law'. We also surveyed participants in the gathering of 34 regional registration authorities to gauge their perception of the registration system. The analysis revealed that the registration with 'Library Law' is a permission system in terms of procedure and method but has the effect of notarization. The estimated national registration rate is 26 percent. The perception survey of the registration authorities' officials exposed the registration-related problems such as inconsistency described in supplementary note, excessive workload, difficulties in staffing, and ambiguity in registration criteria and target. To remedy these problems, we proposed an alternative method for the government to increase the effectiveness of 'Library Law'.

A parallel importation is a non-counterfeit product imported from another country without the permission of the intellectual property owner. It is caused by price differences between countries. Therefore parallel importation are implication in issues of international trade and intellectual property rights(hereafter referred as IPR). This paper provides parallel importation issues of Korea and China under the IPR laws such as patent, trademarks, copyright and analyzes difference between two countries. In China, patent law regulates exhaustion rights which is based theory of a parallel import for the first time unlike trademark law and copyright law. On the other hands, Korea rules parallel importing under Korean customs regulations. In conclusion, two countries have no provisions that advocate a parallel import under IPR laws. This paper suggests some improvements to overcome the limitation of current regulation system and avoid trade friction between two countries. First of all, two countries should clearly make a rule about parallel import in IPR law such as definition of parallel importation, genuine goods, permission conditions, importing proses, penalty and remedy etc. Secondly, two countries should prohibit an abuse of a exclusive import agent's rights and manage a parallel importer not to cause consumer's complain about goods to expansion parallel imports. Finally, two countries should cooperate not to cause disputes about this issue with a communication channel.

For temporary excavation support in a congested urban area, the strand of ground anchor should be removed to get permission of the private land to install anchors. But the strand doesn't need to be removed in the outside city area after use. So the anchor body, tension anchor, is fabricated in-situ. The unbonded length of This anchor has several strands, which wrap only one sheath. When the anchor body is carried into job-site or installed in the bore hole, the sheath is torn easily because it is a very week material. So the grout permeate into the torn sheath. Because of that, the load doesn't transfer to the bond length of ground anchors. It may indicate that load is being transferred along the unbonded length and thus within the potential slip surface assumed for overall stability of the anchored system. The load tests were performed on seven low-pressure grouted anchors installed in weathered soil to verify its problems. Four anchors(Type A) have the unbonded length, which consist of five strands and a week sheath and three anchors(Type B) have strands, which is covered by plastic sheath filled with grease, in the unbonded length. Both anchors are compared with load tests results.

RBAC is an Access Control Mechanism for security administration of system resource and technique attracting in commercial fields because of reducing cost and complexity of security administration in large network. Many RBAC's research is progressive but several problems such as the delegation of role have been pointed out concerning the mechanism. It is necessary that a person's role delegate someone with reliability by reasons of a leave of absence, sick leave and the others. But the existing RBAC standards don't give definition of the delegation of roles. In this paper, we propose RBAC model that delegator can delegate subset of role and permission to a delegatee so that more efficient access control may be available.
