In order to answer the challenge that development gave to environment, Chinese cities are making up and putting into effect the green space system planning. The planning main keys are: set down standards and scope of green space; bring the characteristics of every types of green space in to full play and made into basic units of the system; formed powerful links of the system; make full use of the natural system of city, constituted the urban and countryside as a organic whole green space system, therefore give full play their function and ecological effect. In fact, this green space system is a complex system. It is the main body of city ecological system, a main container of the citizen activities of leisure and recreation and a leading factor for making characteristic city landscape. Therefore it is a system carrying city's environment sustainable development.

In this study, the network analysis of researchers, institutions, and research principal agent was conducted to understand structure characteristics of international cooperation research project implemented from 1997 to 2018. The network of researchers and institutions were decentralized structure. On the other hands, the network of research principal agent was centralized structure. The Soul National University is the leading organization of international cooperation research project. In terms of research principal agent, corporation is the leading principal agent. In additions, the results of the network centroid analysis of the researchers and institutions were correlated with the research funds. As a result, it was confirmed that the network centroid of research organization was linearly related to research funds.

The United Nations' Millennium Development Goals (MDG) has become a goal to create a sustainable life. The MDGs' target was to be achieved in 2015, but it missed that date. The MDGs' target has turned into a Sustainable Development Goals (SDGs) to be achieved by 2030 The SDGs require financial support from companies. Funds are one of the resources to implement the SDGs. Government and private companies need to cooperate in achieving the SDGs target. The company has a responsibility to implement corporate social responsibility. The company's corporate social responsibility is part of the implementation of sustainable development in the SDGs. One of the essential industries that have responsibility for SDGs is the financial industry. This study aims to examine the determinant of corporate social responsibility funds in financial institutions in ASEAN countries. This study uses panel data to test the determinant variables on CSF provision. This study uses 45 sustainable development reports from 2015-2019. The total number of banks in the sample came from three countries, namely, Indonesia, Malaysia, and Thailand. This study concludes that firm size, profitability, efficiency, and the age of the CEO are variables that influence the size of corporate social responsibility funds.

The relationship between sound and vision was experimentally confirmed by physicist Ernst Florens Friedrich Chladni as early as the 18th century and formally entered into systematic research. With the development of emerging media technology, sound reactive type visual content is not limited to a single visual interaction based on the vibration of sound, and its visual content shows a diversified and scalable development trend according to different purposes in many fields. This study analyzes the development and changes of sound visual art contents from early stage to modernization, and analyzes the development characteristic of sound visual art content in different fields and scene environments influence by interactive media, new media technologies and devices by means of case analysis. Through this research, it is expected that the sound reactive type visual art content can continue to develop and extend in the existing fields, while explore the scalability of the application of sound reactive type visual art content in more fields.

This narrative review describes genomic characteristic, serotyping, immunogenicity, and vaccine development of Streptococcus pneumoniae capsular polysaccharide (CPS). CPS is a primary virulence factor of S. pneumoniae. The genomic characteristics of S. pneumoniae CPS, including the role of biosynthetic gene and genetic variation within cps (capsule polysaccharide) locus which may lead to serotype replacement are still being investigated. One hundred unique serotypes of S. pneumoniae have been identified through various methods of serotyping using phenotypic and genotypic approach. The advantages and limitations of each method are various, emphasizing the need for accurate and comprehensive serotyping for effective disease surveillance and vaccine targeting. In addition, we elaborate the critical role of CPS in vaccine development by providing an overview of immunogenicity, ongoing research of pneumococcal vaccines, and the impact on disease burden.

These days international trade has been converting to e-Trade formation. At this point, Korea has been striving for the trade facilitation; reducing logistics cost and improving foreign competitiveness by computerization operations of the maritime transportation that logistics and customs clearance are involved. However, due to the substantial characteristic of logistics service, the necessity of flexible and various logistics service development using internet has been strongly suggested. In particular, the logistics service which could share documents related to international physical movement between shippers and logistics organization. In this regard, this study carried out interview to explore the problems of physical distribution service and to suggest development direction of e-logistics service. The reason why this survey carried out is that most of users want more effective e-logistic service that could diminish successively real expense decrease. After analysis of survey results, this paper presents the basic development direction and emphasis development subjects. Therefore, the basic direction is presented from four viewpoints; customer-oriented approach, service-oriented approach, total approach and step-by-step implementation. Furthermore six development subjects; web-based standard module development for small and medium forwarders, development of standard logistics ERP system, collaboration model between KTNET and KLNET, system improvement for real users, on-demand system building for SMEs and connection with legacy system have been required.

Sclerotial development of Grifola umbellata(Pers. : Fr.) Donk was investigated through microscopic examinations. The sclerotium of G. umbellata was bumpy and rugged, multi-branched, and dark-brown to black in color. The sclerotial development of G. umbellata was categorized into three stages such as sclerotial initial, development and maturation. Sclerotium development was initiated as the white fungal mass. The superficial part of white sclerotium changed into gray, light brown and then black as its development proceeded further. As a distinctive characteristic of this fungus, a large number of crystals were observed in the medulla layer of sclerotium during its maturation. For development of new sclerotium, G. umbellata formed a white sclerotial primordium on the matured sclerotium. Development of sclerotium in G. umbellata was intimately associated with rhizomorphs of Armillariella mellea and the developing sclerotia were often penetrated by rhizomorphs of A. mellea into medulla layer.

The appearance of many Glass Fiber Reinforced Plastic (GFRP) constructions look like ordinary steel construction, because GFRP has been imitated by the same way with the traditional steel's cross section as well as connection system. In terms of detachable connection, there was not enough appropriate option of GFRP connection, such as a traditional bolt connection for steel and wood structures. Most of all, from material characteristic of GFRP related to the deficient ductility, the shearstress principle of GFRP s not proper for the material property, which causes ineffective and not economic application of material. With this research problem, the innovative and detachable onnection system, which is more considered with appropriate material characteristic for FRP, is developed. Not only short time but also long time research with various connection variations is carried out.
