Recently interest in civic engagement and civic service is increasing. However, in Korea, few studies have focused on civic service. This might be on account of general awareness that civic service is fundamentally different from the basic spirit of voluntary work, while interest in paid volunteer work is on the rise. Thus, it is necessary to examine whether civic service is the real antipode of volunteer work. Under this kind of critical viewpoint, this study aims to analyze civic service based on the attributes of voluntary work and civic service. The major findings are as follows. Firstly, contrary to common belief, civic service has not been established to go beyond the principle of voluntary and unpaid characteristics of volunteer work. Rather, some voluntary work has broken out of principle of voluntary activities. Secondly, civic service and volunteer work might be characterized as different not due to spontaneity and unpaid service but the structural characteristics of the goal, continuity and formality. Furthermore, the reason for the soft landing of civic service in the United States is not because they have supported the reimbursement of expenses and the provision of stipends. Rather, it is because their long-term activities have promoted real community development for the purpose of finding solutions to social problems, and they have derived a sense of pride and satisfaction from social recognition and rewards for their contributions.

The purpose of this study is to analyze the cases related to the multi-dimensional urban planning and its related systems that can contribute to the urban regeneration as the policies and projects for stereoscopic city increase. Through the case analysis, urban regeneration function and role of multi-dimensional urban planning are identified as connection of places, activation of local economy, expansion of infrastructure and supply of housing. In the institutional sector, private participation is hindered due to the ban on the establishment of the right to hold state property. In addition, it is difficult to utilize the three-dimensional urban space without land securing at a certain rate based on uniform installation standards of the two-dimensional land use plan, and the problem of insufficient interconnection between law and institution is derived. In conclusion, it should actively support and promote the promotion of the three-dimensional facility with the aim of diversifying the regional infrastructure structure and strengthening the urban function. In addition, development of stereoscopic and compound development should be promoted for old urban areas, and parking lots, underground shopping malls, parking lots, etc. should be installed using the subspaces of parks, schools, roads and traditional markets of old residential areas. Finally, cooperation between the central government, the municipalities and the private sector is necessary for the realization of these urban regeneration projects.

South Korea has recently emerged as one of the leading countries conducting clinical trials. Seoul, for instance, is now ranked at the top of the list among the cities in the world. This paper examines the rapid growth of research involving human subjects in Korea, not just from the economic perspective (e.g., the growth of global pharmaceutical markets and the subsequent increase in the demand for clinical trials), but from the policy perspective (e.g., the government?s drive to support and promote this field as a new industry). The industrialization of clinical trials in Korea has manifested itself in the rise of international Contract Research Organizations (CRO) doing their business in Korea. They are, figuratively speaking, invited to Korea by the government. This paper intends to uncover and discuss the bioethical issues concerning research on human subjects, the issues that tend to be set aside merely as procedural ones like ??workable documents??. To this end, it investigates the practice of clinical trials by collecting hitherto unherad voices from patient-volunteers, physician-researchers, CRO employees, and government officials. This paper also explores the themes of ??ethical variability?? and ??biocapital?? in order to compare and constrast the case in Korea with those in other countries.

In the remodeling projects, clients without architectural expertise have limitations in presenting requirements accurately. In some cases, designers and contractors may not recognize their demands exactly, and deliver final products that are different from the clients' intentions. 3D modeling visualizing final products in previous has been regarded as a solution to enhance understanding and communication. However, this approach has the limitation that the final results are presented as a virtual outputs. In the remodeling project, an alternative, mixed-reality, is likely to reinforce the reality as it enables to present remain structure and the parts to be built together. This paper examines the mixed reality as a solution to support decision making of clients and practitioners in remodeling projects. The examinations is conducted in high-rise office remodeling projects by means of action-research. Clients and practitioners, overview product models presented in the format of 2D drawings, BIM and mixed reality asked to evaluate the effectiveness of each methods in 12 standards. The results have shown that mixed reality has improved the sense of reality, making it easier to predict results, but recognizing patterns is difficult in some areas such as the floor, and it caused dizziness.

The strengthening of multilateral international sanctions against North Korea has raised questions as to how effective they are in exerting pressure on the country's economy. In this paper, we address this question by examining their impact on the country's integration into regional and global apparel production networks. North Korea has in the past decade become an increasingly competitive exporter of apparel on the basis of consignment-based processing arrangements. Official trade data shows a sharp drop in North Korean exports of clothing since the sectoral ban in 2017. There is evidence to suggest, however, that exports have continued on a more informal and clandestine basis. North Korea's integration into apparel production networks has also taken the form of the dispatch of workers to factories in China's northeastern border regions. Yet there is evidence that the recent sanctions imposed on such practices has similarly led to illicit practices such as working on visitors' visas, often with the help of Chinese enterprises and local government. The resilience of North Korea's integration into apparel production networks follows a capitalist logic and is result of the highly profitable nature of apparel production for all actors concerned and a correspondingly strong desire to evade sanctions. As such, the analysis contributes to the literature on sanctions that suggests that the measures may contribute to emergence of growing informal and illicit practices and to the role of the clandestine economy.

Although this site is designed with a non-vibration excavation method for a section of 265 m, there are concerns about decline of constructability and economic feasibility. For this reason, the low-vibration electronic detonator blasting method was suggested. To evaluate the applicability of the low-vibration electronic detonator blasting method, the damage range of blasting vibration of low-vibration electronic detonator blasting applied just before the site (suggestion I) and low-vibration electronic detonator blasting constructed close range the subway like this site (suggestion II) was analyzed. As a result of comparing the blasting vibration damage ranges of the two suggestions, the damage range of suggestion II was calculated more conservatively. Considering the specificity of the close range of this site, suggestion II was selected for design change for safer construction. As a result, it is predicted that there will be no damage to the structure even if the 72 m section out of the non-vibration excavation 265 m section is changed to the Low-vibration electronic detonator blasting. And it is evaluated that high economic benefits can be obtained because the total expected excavation period can be reduced by 144 days from 662.5 days.

The conventional single-core PBDs have been widely used in order to accelerate consolidation settlement of soft grounds. When using the single-core PBD in a thick clay deposit, a delay of consolidation may occur due to high confining pressure in the thick deposit and necking of drains. This study is to compare the performances of soil improvement by the single-core and double-core PBD installed at a site in Busan New Port which exhibits approximately a 40m-thick clay layer. An in-situ test program was performed at the test site where a set of the double-core PBDs and single-core PBDs were installed to compare the efficiency of each drain. In addition, the discharge capacity of each PBD has been measured using the modified Delft Test. A series of laboratory tests for estimating in-situ soil properties have also been performed in order to obtain input parameters for a numerical program ILLICON. The discharge capacity of the double-core PBD is higher than that of the single-core PBD in the modified Delft Test. However it is observed from the comparative in-situ test and numerical analysis that there is no difference in the performance of ground improvement between the two drain systems. This discrepancy comes from the fact that the amount of water released during consolidation in most common field conditions is much smaller than the capacity of even the single core PBD. And thus, considering actual field conditions, it can be concluded that the single-core PBD has enough discharge capacity even in the thick clay deposit such as this test site.

As COVID-19 has led to a surge in e-commerce Buy Now Pay Later(BNPL) has become preferred choice among millennials. In Korea Coupang followed by Naver Pay offers a deferred payment, aiming to create customer lock-in effect, save credit card processing fee and lay the groundwork for entering into new financial services. However the literature related to the influential factors of customers' usage intention toward a deferred payment is scarce. For the study, a multi-group analysis was carried out to find differences between Naver shopping and Coupang. The results revealed that the important factors that affect a deferred payment adoption were compatibility, impulsive buying tendency in Naver shopping, whereas compatibility, relative advantage, additional value in Coupang(listed in order of most important). In addition, impulsive buying tendency had a positive effect on adoption intention in Naver shopping and on perceived risk in Coupang. The results imply that Naver shopping need to focus on managing delinquency while Coupang should provide sufficient information on how late fees and credit rating downgrade work and try not to make a deferred payment option stand out. In order to increase adoption rate it is recommendable to narrow down target segment of a deferred payment and expand it to a specialized vertical such as travel.

Cementitious matrix based composites are vulnerable to the drying shrinkage crack during the curing process. In this study, the drying shrinkage induced fracture behavior of the fiber reinforced concrete is simulated and the effects of the fiber reinforcement conditions on the fracture characteristics are analysed. The numerical model is composed of conduit elements and rigid-body-spring elements on the identical irregular lattice topology, where the drying shrinkage is presented by the coupling of nonmechanical-mechanical behaviors handled by those respective element types. Semi-discrete fiber elements are applied within the rigid-body-spring network to model the fiber reinforcement. The shrinkage parameters are calibrated through the KS F 2424 free drying shrinkage test simulation and comparison of the time-shrinkage strain curves. Next, the KS F 2595 restrained drying shrinkage test is simulated for various fiber volume fractions and the numerical model is verified by comparison of the crack initiating time with the previous experimental results. In addition, the drying shrinkage cracking phenomenon is analysed with change in the length and the surface shape of the fibers, the measurement of the maximum crack width in the numerical experiment indicates the judgement of the crack controlling effect.

Objectives: Nuclear security and atomic energy industry have always been the domain of political and economical diplomatic affairs. The issue of nuclear proliferation must be resolved politically or militarily given the importance of the problem, the impact it has on global security, the influence of major powers, and non-proliferation regimes. Considering scope of the budget, manpower, and scale of the project, the atomic energy issue was also viewed from an economic perspective. Therefore, the goal of this study is to depart from the conventional viewpoint and investigate if public diplomacy may be extended to a new issue domain of nuclear security and atomic energy. Methods: In order to determine whether there are any areas that overlap, the uniqueness of Korea's position in the nuclear security and atomic power domains is evaluated and compared with the traits of public diplomacy. Results: It seems plausible to broaden the scope and function of public diplomacy in that field given Korea's uniqueness in nuclear security and atomic energy issue and overlap with public diplomacy. This is especially true given that the state must take the leading role and that ongoing policy demands are made in light of Korea's security and economic structure. In reality, it is assessed that the Summer Fellows Program, run by the KAIST Nuclear Nonproliferation Education and Research Center (KAIST NEREC), has had a considerable impact on public diplomacy in the area of nuclear security and atomic energy. Conclusions: Nuclear security and atomic energy issues have traditionally been handled from the perspectives of political diplomacy, summit diplomacy, and economic diplomacy. However, this paper evaluate that the possibility of enhancing the role of public diplomacy in this issue area is high and underscore that the budget support, programs, and manpower for similar public diplomacy activities are needed. Through this, South Korea's nuclear security policy and atomic energy industry could be supported from international community and it will advance national interest.
