The development of food poisoning prevention guidelines aims to prevent food poisoning in advance and improve the safety of children's meals through hygiene management of children's feeding facilities, especially infants' facilities. Therefore, the composition of the content should be designed so that it can be fully understood from the point of view of the layperson. In terms of meal service management, various standards must be fully reflected and reviewed to increase utilization in the field. Daycare centers and kindergartens have different administrative agencies, similar application laws and guidelines, but different parts exist and various types of facilities, so management standards are often ambiguous. Therefore, such management requires easy guidance, not special guidance, and it should be universally applicable to any facility. Prior studies have shown that the management of meal facilities is the most efficient, but it is difficult to hire and deploy specialists due to the operation of children's meal facilities, so guidance, facilities managers and workers need to voluntarily practice them. It is time to prepare hygiene guidelines that reflect the characteristics of these children's cafeterias, and it is necessary to prepare and utilize guidance suitable for reality until it is institutionalized for the deployment of manpower exclusively for meals.

This study was developed to investigate the effects of privately owned public space (POPS) on urban streetscape and to find ways to prevent the discontinuation of street continuity on urban landscape when creating POPS in urban space and the surrounding streets. Several case studies and policies and laws related to POPS were reviewed to identify the practical problems as well as current state. An additional analysis was conducted on the different types of POPS to examine spatial connections between them and streetscapes and to find ways to improve POPS on urban streetscape. Our results show that POPS surrounding a building (i.e. frontage space and adjacent sidewalks) should be considered as one space in the integrated perspective. In addition, the type of facilities installed on POPS would be decided according to whether POPS is recognized as the part of public rest area or treated as the part of street. The results of the study will serve as useful data to solve the current problems with city's POPS, which destroys spatial continuity by focusing on increasing the number of POPS and creates high-rise buildings isolated from existing spaces. This study will also contribute to improve the quality of future POPS.

The Philippines is a naturally water-rich archipelago capable of sustaining its ecological goods and providing services and needs of its people. Several waterbodies have been declared as natural wetlands in the country supporting the needs of community like water and food. In this study, 65 natural wetlands were considered including six sites that were identified as 'Wetlands of International Importance' such as Naujan Lake National Park, Agusan Marsh Wildlife Sanctuary, Olango Island Wildlife Sanctuary, Tubbataha Reefs Natural Park, Las $Pi{\tilde{n}}as-Para{\tilde{n}}aque$ Critical Habitat and Ecotourism Area and Puerto Princesa Subterranean River National Park. There are 22 wetland types presented in this research categorizing the Philippine wetlands. Philippine wetlands are now facing tremendous challenges such as land use conversion, abuse of resources, pollution coming from domestic, industrial and agricultural activities, and climate change. This paper provides an overview of Philippine wetlands in terms of their characteristics and components, impacts in the ecosystem, and the challenges they are dealing with. Moreover, the preservation measures that the government and private agencies implements to these wetlands were discussed and assessed. The enforcement of local and national laws concerning wetlands is found to be inadequate resulting in poor quality wetlands. The preservation and utilization of these wetlands can be maximized with a voluntary participation of whole Philippine community.

Steganography is being used as a means of secret communication for crimes that threaten national security such as terrorism and espionage. With the development of computers, steganography technologies develop and criminals produce and use their own programs. However, the research for steganography is not active because detailed information on national security cases is not disclosed. The development of investigation technologies and the responses of criminal law are insufficient. Therefore, in this paper, the detection and decoding process was examined for steganography investigation, and the method was analyzed for 'the spy case of Pastor Kim', who was convicted by the Supreme Court. Multiple security devices were prepared using symmetric steganography using the pre-promised stego key. Furthermore, the three criminal legal issues: (1) the relevance issue, (2) the right to participate, and (3) the public trial issue a countermeasure were considered in national security cases. Through this paper, we hope that the investigative agency will develop analysis techniques for steganography.

The purpose of this study is to analyze precedents related with child abuse for protection of the rights of the child. There should be the law related with 'punishment for child abuse,' which is the grounds of punishment, to make a precedent in the law punishing for 'child abuse,' but there is the concept only for 'child abuse' in the Child Welfare Law, the fundamental law; therefore, for a direct judgment for punishment, only precedents of 'child abuse' related with loss of parental rights and judgements for criminal cases, civil cases and laws covering special cases have been made. For that reason, 'the special law related with punishment for child abuse cases' is desperately required (On last December 23, 2013, the special law related with punishment for child abuse cases passed the National Assembly). Hence, precedent analysis had performed by grouping precedent from 2000 to 2013 which were not judged as child abuse in trial but can be regarded as child abuse. When analyzing each precedent according to the contents of analysis and judgment by fact relevance in this study, problems which the current legislative system has were deducted through an implication of each case by diagnosing using diagraming after classifying lower instance terminated cases, which precedents of the Supreme Court and judgments sent to the Supreme Court were excluded, while excluding cases settled in the civil level and classifying analysis of civil case precedents which did not become a criminal case and completed as a civil case, analysis of criminal case precedents, classification of precedents of loss of the parental rights (regarding child abuse) and precedents of any other special laws. And compensatory tasks for special laws regarding punishment of child abuse were presented while suggesting compensatory tasks for the legislation regarding deducted problems.

The purpose of this study is to analyze endangered species laws and systems in China from the viewpoint of the importance of protecting biodiversity and to propose suggestions for existing wildlife protection laws in China to improve efficacy. Since the People's Republic of China Wildlife Protection Act was promulgated and enforced in 1988, China has found that urgent amendments are necessary because of neglected management of the act. The content of the Wildlife Protection Act of China is not only monotonous and unsystematic, but also needs modification and supplementation because it is pre-modern and does not meet current demands. In comparison with other countries, the purpose of China's legislation, supervision system, scope of protection and public participation system differ. China's Wildlife Protection Act is also hindered by confusion in the legislative protection system, lack of an administrative compensation system, difficulties in implementation, deterioration of legal efficiency, lack of content and operations, and lack of a list of species that should be is protected. This paper proposes measures for improvement to solve this confusion in the legislative system for the endangered species protection law to establish a legal system suitable for the current situation in China.

Uncoupled, quasi-static and linear thermoviscoelastic problems are analyzed in time domain by the finite element approximation which is developed using the principle of virtual work and viscoelasticity matrices instead of shear and bulk relaxation functions as in usual formulations. The material is assumed to be isotropic, homegeneous and thermorheologically simple, which means that the temperature-time equivalence postulate is effective. The stress-strain laws are expressed by relaxation-type hereditary integrals. In spatial and time discritizations, isoparametric quadratic quadrilateral finite elements and linear time variations are adopted. For explicit derivations, the viscoelastic material is assumed to behave standard linear solid in shear and elastically in dilatation. Two-dimensional examples are solved under general temperature distributions T = T(x, t), and compared with other opproximate solutions to show the versatility of the presented analysis.

The bottom of dikes must be kept impermeable to control hazardous chemicals spilled from storage tanks. Currently, insufficient related chemical control laws lead to a possibility to spread through the bottom. Generally, due to the high cost of installation and periodical maintenance, many businesses prefer to install the bottom with general concrete. But, since the impermeability of concrete is dependent on the kind of materials and chemical reaction, all concrete cannot be considered as impermeable material. Thus, it is necessary to make the installation standards of the dike bottom clear in order to avoid the argument over the impermeability and prevent the chemical accident. This study has suggested the standards of impermeable concrete by conducting 7-day exposure test to crude oil with the pilot dikes. The results have showed that the standards have the better impermeable performance compared with the germany standard, which have been penetrated at the maximum penetration depth of 1.9 cm. This study is expected to contribute to both the risk reduction of penetrating into the bottom and the cost reduction of spending to make the bottom of dikes impermeable.

The present work suggests a numerical approach using a thermoacoustic network model for the eigenvalue calculation of thermoacoustic instability problems in an aero gas turbine combustor. The model is developed based on the conservation laws for mass, momentum, and energy between acoustic network elements with an area change. Acoustic field in a practical aero gas turbine combustor which has a complicated flow path is analyzed using the current model. The predictive capabilities of the current modeling approach are compared with the acoustic characteristics calculated using Helmholtz solver based on 3D finite element method(FEM).
