In this study aims to provide operational guidelines based on risk assessment and safety evaluation in the operation of non-traditional oil production plants, serving as alternative resources in comparison to conventional oils within the construction sector. Presently, operational facilities within these plants are active. However, integrating comprehensive management through sectional and device-specific diagnostic and evaluation systems in similar platform-based operational management systems proves to be a challenging reality. Consequently, this research introduces an evaluation methodology tailored for an operation-centric management system using an integrated management approach, and evaluates its practical applicability within the construction field.

This paper critically examines the existing discourses about 'relationship', a key element of social work practice and questingly examines Lao-tzu's work of Tao Te Ching, the book of way and virtue, as an alternative theoretical framework for social work relationship. Compared to current discourses of relationship beleaguered by either modernism or postmodernism, both of which are in the deadlock of binary perspective, the insights and vision in Tao Te Ching are successfully able to overcome the limits of them and provide new and profound way of thinking about human, society and their relationship. Especially core cannons crystallized by natural humanistic concepts for cosmos coupled with innate critical power against artificial manipulations of world can extend the horizon of understanding concerning the relationship between client and social workers and therefore provide a new and attractive roles in professional relationship. Moreover, opposed to usual images of Lao-tzu's ideas such as nihilism and passivity, alternative relationship of social work can play an important role of caring the disordered reality where Dao disappered and criticise the selfish desires of individuals and comport the broken-hearted minds in modern society. In addition, results of this paper implies that more extended study articulating ideas of Tao Te Ching with the social work practice would have lots of potentials to promote later researches in quest of 'Korean' social work practice.

At present, in the case of small and medium window manufacturers in South Korea, glazing and window frame manufacturers are divided into separate businesses. However, in the fenestration energy consumption efficiency rating system and the energy-saving design criteria for buildings, the coefficient of overall heat transmission standard for windows is defined by window sets, which integrate glazing and window frames. At most construction sites, windows are constructed by installing separately supplied glass and frames. Research that can integrate the reality and the system is therefore necessary. The present study first investigated and analyzed the on-site situation of the fenestration energy consumption efficiency rating system. According to the results, while overall understanding of the fenestration energy consumption efficiency rating system was high, satisfaction with it was low, and the general practice at construction sites was to use windows assembled on site rather than integrated window systems manufactured at factories, thus making it difficult to confirm that the current rating system was well applied on site. Consequently, the reality of industrial sites must be reviewed and a realistic alternative to the fenestration energy consumption efficiency rating system must be presented instead of focusing on theory.

This paper is to consider trends and issues of regional research in major sub-fields of human geography in Korea, following the previous one which dealt with contexts and general trends of new regional geography in Korea since the 2000s. They include historical and cultural geography on place and landscape, economic geography on industrial districts or agglomerated regions (i.e. clusters) and urban (and social) geography on urban networks and differentiation. Even though researchers in sub-fields have used different terms and concepts to identify region, they are in common to relate specificities of region to general processes such as (de)modernization, (de)industrialization, and globalization, to understand region as social and discursive constitution as well as substantive reality, and to give more attention to socio-spatial networks and relationality than territoriality of regions. These common points seem to reflect the emerging trend of new regional geography, and to get rid of existing traditional concept of region. It is suggested that major tasks for conceptualization of region in future research are to overcome dichotomy of speciality and generality, of substantive reality and discursive constitution, and of territoriality and relationality, and that important issues for empirical research on region include regional synthesis from new perspectives, uneven regional development as relational process in and between regions, and producing practice for alternative regions.

COVID-19 is putting the entire performance industry in a dire situation. One of the approaches to overcome this crisis is contactless performance business using video media. But, these contactless performance videos are now found to have their own issues. First, with the increasing demands for these videos, the need for higher-quality video products is also increasing. However, there are many organizations that cannot afford such an investment. Second, it is not possible to have the same unique experience of a live performance with the videos. 360-degree VR performance videos are now gaining attention as an alternative to cope with this issue. As such, the researcher reviewed the production of 360 VR performance videos in general based on the cases of the play and a children's story concert As a result, the researcher could confirm the three benefits of simulated 'live experience through a sense of reality', 'convenience of filming' and 'continuity of acting'. Also, the issues related to this approach including 'Lack of professional filming companies', 'Expensive viewing equipment', 'Absence of Platform' and 'Limitations of Camera Technology', among others have been identified, etc. Based on these findings, the researcher could propose strategies for improvement in order to utilize 360-degree VR performance videos.

The purpose of this study is to suggest a response and solution through Christian educational care to the crisis and change of the era of low birth rate faced by Korean society and the Korean church. This study proposes to find an alternative to the biblical aspect of pregnancy, childbirth, and parenthood as God's blessing for the demographic cliff and low birth rate problem that have become a reality in Korean society and churches. Being a parent in an age of low birth rate is very difficult, but on the other hand, it gives happiness and joy. Being a parent is a blessing from God, and is the most important and valuable thing in life. However, modern society emphasizes the right and necessity to choose one's own parenthood status. In the nuclear family, the decrease in the number of children, and the development of child research, parents feel more responsibility and economic burden for raising children than ever before. Therefore, it is a reality that the number of people who delay becoming parents or voluntarily do not have children is gradually increasing. To improve the perception of becoming a parent due to a decrease in responsibility for raising children, it is necessary to shed light on marriage, pregnancy, childbirth, and childrearing from a Christian educational point of view. In addition, it is necessary to understand the recognition of being a parent and the characteristics of childbirth and rearing, and to analyze past and present value changes. This study will also discuss the causes of low birthrate and try to provide Christian educational care for childcare including solving the low birthrate problem.

Background: DNA vaccination represents an anticipated approach for the control of numerous infectious diseases. Used alone, however, DNA vaccine is weak immunogen inferior to viral vectors. In recent, heterologous prime-boost vaccination leads DNA vaccines to practical reality. Methods: We assessed prime-boost immunization strategies with a DNA vaccine (minigene, $gB_{498-505}$ DNA) and recombinant vaccinia virus $(vvgB_{498-505})$ expressing epitope $gB_{498-505}$ (SSIEF ARL) of CD8+ T cells specific for glycoprotein B (gB) of herpes simplex virus (HSV). Animals were immunized primarily with $gB_{498-505}$ epitope-expressing DNA vaccine/recombinant vaccinia virus and boosted with alternative vaccine type expressing entire Ag. Results: In prime-boost protocols using vvgBw (recombinant vaccinia virus expressing entire Ag) and $vvgB_{498-505}$, CD8+ T cell-mediated immunity was induced maximally at both acute and memory stages if primed with vvgBw and boosted with $vvgB_{498-505}$ as evaluated by CTL activity, intracellular IFN-staining, and MHC class I tetramer staining. Similarly $gB_{498-505}$ DNA prime-gBw DNA (DNA vaccine expressing entire Ag) boost immunization elicited the strongest CD8+ T cell responses in protocols based on DNA vaccine. However, the level of CD8+ T cell-mediated immunity induced with prime-boost vaccination using DNA vaccine expressing epitope or entire Ag was inferior to those based on vvgBw and $vvgB_{498-505}$. Of particular interest CD8+ T cell-mediated immunity was optimally induced when $vvgB_{498-505}$ was used to prime and gB DNA was used as alternative boost. Especially CD7+ T cell responses induced by such protocol was longer lasted than other protocols. Conclusion: These facts direct to search for the effective strategy to induce optimal CD8+ T cell-mediated immunity against cancer and viral infection.

Of the numerious dispute resolution methods, Alternative Dispute Resolution(ADR) is the most highly recommended approach for the guarantee bond-related dispute. In reality, however, claims were not resolved satisfactorily through ADR because of the lack of reference materials for negotiation, thus those were frequently had to be resolved through litigation. The above fact implies that, it is required to seek an efficient way to resolve the bond-related claims prior to they progress to litigation. This research paper intensively investigated judicial precedents of 232 cases with regard to construction bond-related disputes that observed during the analysis period(2000-2004). According to the summary statistics, it turned out that litigation were time consuming and potential economic loss was tremendous; on average, it takes 1067 days(the longest case was 1965 days) for dispute resolution. It suggests that litigations should be discouraged considering the magnitude of potential loss of stake holders. Research results revealed that there are some significant differences between categories in some variables affecting to the rate of winning; i) the number of lawsuit deputies of a plaintiff (in the 1st trial), ii) dispute locations (in the 1st and 3rd trials), iii) contract price (in the 1st trial), iv) contractors' operating capability (in the 1st and 2nd trials). For the rest of variables, significance level between categories was too low for preparing efficient improvement plan. Despite the important implications drawn from the analysis, this research has limitation due to the several reasons such as data structure, the depth of Information, etc. Therefore, more systematic research should be followed in the future.

In this study, Private investigation in South Korea, while gone through so far of politics, the process of social change, a positive feature, without evolve, insufficient growth and security services of the business burden of national judicial institutions, detective industry international of the negative vicious circle, such as the acquisition of drop and expedient information of competitiveness is continuously induced it is a reality. It is, therefore, to the proposal, such as the following. First, it must be able to use the term "detective". Secondly, in order to verify the validity of this system, after introducing the first private sphere, in accordance with the stepwise its necessity, it is desirable to extend the operational range of the public area. Third, to have a country of qualification to private research workers, will be managed directly from the country is ideal. Fourth, we must also seek plan to specialize the designated educational institution as a commissioned education institution to institution with a faculty and facilities that are specialized. Fifth, the National Police Agency must manage and supervise the private investigation business. Sixth, the legislative form to amend the current security law, as a kind of private security, must be introduced by adding a private trillion business. Therefore, in order to complement the limitation of such studies, additional subsequent research has if it is not carried out.
