The Korean domestic construction management at risk (CMAR) market is in the process of completing the pilot project execution under the leadership of the Ministry of Land, Infrastructure and Transport as of December 2019. The government starts practicing CMAR an alternative delivery method widely in order to diversify delivery methods and enhance construction technology. The CMAR market is thus expected to grow. This study was conducted to improve CMAR firms' capability by developing self-assessment tools for them to evaluate current capability more effectively. As a result of defining standard core capability and additional elements categorized by project execution phase and management area, and performing evaluation from the CMAR project participants, it was found that the general project management capability in the pre-design and procurement phase and quality management area was lower compared to the construction phase and other areas. In addition, the capability of cost management area was lower in spite of its high importance. Communication and coordination, process optimization, and target values achievement were at the initial level of capability and continuous improvement was required.

Due to urban growth and increasing population density, many large cities contain building forests. Moreover, due to increasing demands for pleasant residential environments, there is growing concern over the encroachment of sunshine. Although research on related laws and other related fields is emerging, there is a limit to the extent to which the public can easily determine the amount of sunshine per building without referral to specialized agencies. Therefore, in this study, the duration of sunshine per building object was calculated via a simulation of urban shaded area using a spatial information open platform application programming interface. The study area was the'L'apartment complex located in the new city, Haeundae, Busan, China. To perform the duration of sunshine simulation for three-dimensional urban spatial objects, the building height was extracted from pre-built three-dimensional spatial information data, and the position of the sun was determined from calculations of the altitude and azimuth of the sun. This study provides a more precise and easier method of judging whether sunshine is impeded from reaching buildings by quantitatively analyzing sunshine and classifying the total duration of sunshine and the continuous duration of sunshine on each object.

Intercountry adoption, one type of forced migration, has increased significantly in recent decades. The adoption of Korea-born children by Americans has been the strongest intercountry adoption linkage in the world. The intercountry adoption stream was strongly influenced by intercountry adoption policies, and socio-cultural settings in both South Korea and the United States. Socio-cultural factors in South Korea made local adoption undesirable and helped for abandoned children to be adopted by Americans, while socio-cultural factors in the United States had reduced the number of locally available infants for adoption, and increased the demand for infants from abroad. Distribution of Korea-born adoptees shows concentration in the Pacific Northwest, Upper Midwest and Northeast areas which have not attracted Korean immigrants so generally. The trend of concentration shows some increased importances in the outlying states in the northern United States. The location and activity of agencies shaped the spatial distribution of Korea-born adoptees in the United States.

Up until recently, Korea has ranked the first place in UN e-Government Survey for three consecutive years. In keeping with such accomplishment, the size of budget execution has been consistently growing in accordance with Korea's Government 3.0 policy and vision, leading to increase in big-sized informatization projects in the business. Especially in mission critical public sector's infrastructure where it affects many people, growing demand for establishing high-quality information system with new technologies being brought to attention in order to meet the complex needs of citizens. National defense information system, being one of representative domains examples in the concerned area, established high military competency by applying breakthrough technology. Network-oriented national defense knowledge informatization was set as the vision in order to implement core roles in making efficient national defense management; and effort has been made to materialize the vision by making advancement in national defense's information system and its informatization implementation system. This research studies new quality index relevant to test and evaluation (T&E)of informatization business in national defense which is the representative example of mission critical public sector's infrastructure. We studied international standards and guidelines, analyzed actual T&E cases, and applied them to the inspection items that are currently in use, complying with the e-government law (Act No. 12346, Official Announcement Date 2014. 1.28., Enforcement Date 2014. 7.29.) As a result of productivity analysis, based on hypothesis in which suggested model was applied to T&E of the national defense informatization business, we confirmed the possibility of enhancement in the T&E productivity by assessing reliability, expertise, and safety as evaluation factors.

In urban areas, underground tunnel construction sites have spread widely to accommodate rapidly increasing traffic volume along with a high-degree economic growth. Earth tunneling might be adapted frequently for the underground space securing, and various tunneling methods have been developed to stabilize the tunnel face and crown. Among them, the DSM (divided shield method) is gaining popularity for its enhanced stability and construction efficiency. This method has its foundation from the Messer Shield method, which is one of the trenchless special tunneling methods. This study examined the effects of face reinforcement on construction the sequence through a large scale soil chamber test and numerical analyses. The chamber has a size of a 1/2 scale of the real tunnel. Surface settlements were measured according the tunneling process. Commercially available software, MIDAS GTS, was used for numerical analysis and its result was compared with the values obtained from the chamber test. The results of the study show that both settlements of the embanked soils and the stress of the tunnel girder are located within the safe criteria. Overall, this study provides basic data and the potential of using a reinforced tunnel face to enhance DSM applications.

Our society nowadays sees the increase in damage from crime on lives and properties by leaps and bounds in line with the economic take-off, and as a result, the raise of individual income. When considering such a hike in crime, it is desirable that the police framework be enhanced. However, thanks to the failure to correspond to this, it could be safely said that a good portion of accountability was shifted to the private security industry in regard to security for the people. Accordingly, the request for escort security business is on the increase regarding expansion and improvement about this industrial sector. As such, it is necessary to get the related system rearranged for authority on the part of escort guards, who are directly exposed to numerous crimes. On top of this, dispersion is required for the escort security businesses centralized in the metropolitan area. It is also necessary for the security guard system to be strengthened and disintegrated into details so that the escort security services are available to people in more safe and easily manners than ever before. When the qualification regime is operated based on this refreshed system, the efficient escort security work would be realized. The dichotomy into act on Special Security Guard and act on Security Business should be dealt with once again for integration as an issue on the front burner in the academic area, and through which the escort security market could be fit for the globalization as well. This paper would provide the solution that leads to more professional and efficient results from comprehension of progress situations in reality by starting from the concept on private security to the analysis of the conditions in this industrial sector.

As the entrepreneurial ecosystem turns out to be a leading factor in improving nation's entrepreneurship, many studies are underway in the country to develop the start-up ecosystem. Although the entrepreneurial ecosystem is receiving attention as an essential factor for the nation's economic growth as well as entrepreneurship due to its inter-relationship with start-ups, government agencies and investors, criticism of measurement indicators has been increasing due to the different institutional and political contexts of each country, including the various definition of start-up ecosystem. In this study, we develop indicators that are suitable for domestic conditions in Korea and that can measure the level of start-up ecosystems in each regional level. FGI and Delphi surveys by scholarly experts in each field of start-ups & entrepreneurship were conducted to verify how well existing indicators fit the domestic situation and to develop indicators that can measure the local entrepreneurial ecosystem in Korea through close examination. As a result, the local entrepreneurial ecosystem consisted of three to four sub-components and 38 sub-components, each consisting of seven indicators, including Policy, Investment, Culture, Market, Human Capital, Support and Knowledge. It is expected that this research will be used to diagnose local start-up ecosystems and to propose discriminatory policies that can complement regional strengths and weaknesses.
