After the COVID-19 pandemic, a global economic downturn and a recession in the shipping market are expected, it is important for domestic shipping companies to establish appropriate strategy in response to the recession. Accordingly, domestic shipping companies should grow into integrated logistics companies that combine shipping and logistics in the future. And for this purpose, it is necessary to actively promote logistics integration with external shipping and logistics companies. This paper presents the direction of logistics integration for domestic shipping companies to develop as integrated logistics operators with competitiveness in the global shipping market, and presents detailed alternatives. Domestic shipping companies lack the infrastructure such as ships, port terminals, and warehouses, so they have a weak capacity to independently promote logistics integration. At the shipping company level, a logistics integration promotion strategy should be established, and accordingly, logistics infrastructure, service network, and logistics integration operating system should be established. The government should provide tax benefits for logistics integration, financial support for M&As led by domestic shipping companies, a standardized information sharing system, and preparation of educational courses for nurturing digital manpower.

Recently BIM technology has been expanded for using in construction project. Due to the high-cost of BIM infrastructure development, lack of regulations, lack of process and so forth, usage of BIM has been delayed than initial expectations. In design phase, especially, collaboration based on BIM system has been a key factor for successful next generation building project. Through the analysis of current research trends about IT technologies, virtualization and BIM service, data exchange such as drawings, 3D model, object data, properties using cloud computing and virtual server system is defined as a most successful solution. The purpose of this study is to enable the cloud computing BIM server to provide several main functions such as editing models, 3D model viewing and checking, mark-up and snapshot in high-performance quality by proper design of VDI system. Concurrent client connection performance is a main technical index of VDI. Through testing of test-bed server client, developed VDI system's multi-connect control is evaluated. Performance-test result of BIM server VDI effect to development direction of cloud computing BIM service for commercialization.

This study aim to figure out the limitation of existing ICT SMEs technology support programs conducted by Government Funded Research Institute. To investigate the limitations of SMEs programs, we conducted Focus Group Interview(FGI) with staff in charge of R&D department of beneficiaries(ICT SMEs). The results of FGI show that SMEs have troubles with the lack of R&D manpower, R&D infrastructure and non-R&D activities. Then, we conducted Delphi survey(derived from FGI) with related field experts to ask the problems and limitations of SMEs programs. The Results of Delphi show that SMEs programs has limitations with avoiding of SMEs support staff, lack of public R&D infrastructure sharing center, incompleteness of policies. Based on the results of FGI and Delphi, we suggest the several ways to improving SMEs programs.

The purpose of this study was to review the government's policy on the enhancement of sports facilities for community residents regarding the lack of knowledge surrounding the infrastructure of sports facilities. The government has invested approximately 2.4 trillion won to establish 220 community sports centers, 385 billion won for 194 multi-purpose indoor centers, and 1.3 trillion won for rebuilding 1,870 school outdoor fields. On the other hand, there are problems with the link between the crumb rubber infill on sports fields and cancer, a lack of availability of indoor sports centers, and an increased federal budget deficit. It is the responsibility of government to plan and construct outdoor fields that are large enough to accommodate all people and allow them to play activities. In addition, the guidelines should ensure that the indoor space required for physical activities at each teaching station is large enough to accommodate all students in the class and handle two classes. The government should suggest the federal government guidelines based on a good understanding of the concept of infrastructure in sports facilities. The government also should make efforts to reduce the regulatory powers and provide the community with an autonomous right to plan and construct sports facilities.

Accident analysis models were developed to improve the construction site safety and case studies was conducted. In 2016, 86% of fatality accidents occurred due to simple unsafe acts. Structure related accidents are less frequent than the non structure related causes, but the number of casualties per accident is two times higher than non structure one. In the view of risk perception, efforts should be given to reduce accidents caused by low frequency - high consequence structure related causes. In case of structure related accident, structural safety inspection and management (including quality), ground condition management / inspection technology, and provision of risk information delivery system in case of non structure related accident were proposed as a solution. In analysis of relationship between safety related stakeholder, the main problem were the lack of knowledge of controller and player, loss of control due to duplicated controls, lack of communication system of risk information, and relative position error of controller and player.

In recent years, several problems occur due to irrational development in rural areas. The first, disorderly development and Encroachment of farmland, Small factory built in rural areas leads to a lack of infrastructure. it is the damage factors of good scenery in the rural areas. Water pollution and environmental pollution from the accommodations and restaurants in the good scenery area is serious. To solve this problems, we should establish the systematic land use plan and landscape plan, and integrated spatial and business plan in rural areas. In order to increase the effectiveness of land use planning in rural projects, We should establish the land use plan in rural areas of the city, state, and national levels of regional plan. We need to prescribe in "National Land Use Planning Law" the facilities, can install it according to the characteristics of rural land programming. we can prescribe the detail regulations by "Rural Maintenance Law". In order to solve the problems the lack of professionalism of the current agricultural policies of the Review Committee, We need to consider a new "rural planning committee" consisting.

The media is an effective means of preventing crime. It can be known to members of the media presiding over the most widely and rapidly. Because of this, the mass media is a good way to prevent such crime. Related to general crime, marine crime will have unique characteristics and about Crimes reported by the media, it is also true. The results of this study are as follows. Firstly, it is required that the more accurate present article must be published and reported. Secondly, for more accurate presentation of measure, there is a need to enhance professional training for reporters. Thirdly, the marine weather report is the most important political purpose of considering marine crime prevention. Forthly, marine crime is likely to be a lack of evidence. Therefore, in order to supplement the lack of evidence maritime security agency should be utilized for a news source.qualification Fifthly, the need for regular inspection of the articles is requested. Sixthly, for judicial control maintenance of the media related laws should be strengthened. Finally, the arbitration institution for media rights should be established under the Korea Ministry of Land Infrastructure and Transport. This is practical action for marine crime prevention.

Because of lack of accurate understanding of the mechanism of urban heat island (UHI) phenomenon and lack of scientific discussion, it is hard to come up with effective measures to mitigate UHI phenomenon. This study systematically described the UHI and suggested the solutions using green-infrastructure (green-infra). The factors that control UHI are very diverse: radiant heat flux, latent heat flux, storage heat flux, and artificial heat flux, and the air temperature is formed by the combination effect of radiation, conduction and convection. Green-infra strategies can improve thermal environment by reducing radiant heat flux (the albedo effect, the shade effect), increasing latent heat flux (the evapotranspiration effect), and creating a wind path (cooling air flow). As a result of measurement, green-infra could reduce radiant heat flux as $270W/m^2$ due to shadow effect and produce $170W/m^2$ latent heat flux due to evaporation. Finally, green-infra can be applied differently on the macro(urban) scale and micro scale, therefore, we should plan and design green-infra after the target objects of structures are set.
