In order to obtain basic informations on establishment of culture system for Cassia tora L. in the southern part of Korea, under vinyl mulching and non mulching conditions, the characters of growth and yield following the difference of fertilization quantity were investigated. All characters, stem length, stem diameter, number of branches, number of pods per plant, pod length, and number of grains per pod, etc., were excellent under the vinyl mulching condition, and of these growth characters, stem diameter, number of pods per plant, and number of grains per pod, etc. were most excellent in the district of N-P$_2$O$_{5}$-K$_2$O=8-6-6Kg /10a. Weight of 1000 grains and seed yield were also high under the vinyl mulching condition, and starting form the district of fertilization quantity N- P$_2$O$_{5}$-K$_2$O=8-6-6Kg /10a, the districts of increasing or decreasing fertilizer tended to be less yield. Also under the vinyl mulching and non mulching, the dispersive analyses of useful characters following the difference of fertilization quantity, were acknowledged to be worth of attention.

Many nucleoside diphosphate (NDP) kinases are ubiquitous enzymes responsible for the exchange of ${\gamma}$-phosphates between tri- and diphosphonucleosides. The catalytic Many nucleoside diphosphate (NDP) kinases are ubiquitous enzymes responsible for the exchange of ${\gamma}$-phosphates between tri- and diphosphonucleosides. The catalytic reaction follows a ping-pong mechanism in which the enzyme is transiently phosphorylated on a histidine residue conserved in all nucleoside diphosphate kinases. Beside their role in nucleotide synthesis, these enzymes present additional functions, possibly independent of catalysis, in processes such as differentiation, cell growth, tumor progression, metastasis and development. To clone murine nm23-M5, several expressed sequence tags (ESTs) of the GenBank data base, selected according to their homology to nm23-H5 cDNA, reconstituted a complete open reading frame (GenBank AF222750). To test whether murine NDPKs (1, 2, 3, 4, 5, and 6) can inhibit Bax-mediated toxicity in yeast, co-transformation was performed respectively. The yeast S.cerevisiae was transformed with a copy expression plasmid containing the histidine selection marker and expressing murine Bax under the control of a galactose-inducible promoter. Several clones were selected and found to be growth inhibited when Bax expression was induced with galactose. A representative clone was transformed again with a copy expression plasmid containing the tryptophane selection marker and expressing either murine Bcl-xL or NDPK under the control of a galactose-inducible promoter. Several subclones of the double-transformants were selected and characterized. The ability of Bcl-xL and NDPKs to suppress Bax-mediated toxicity was determined by growing yeast cells overnight in galactose media and spot-testing on galactose plates starting with an equal number of yeast cells as determined by taking the OD$_{600}$. Ten-fold serial dilutions were used in the spot-test. Plates were grown at 3$0^{\circ}C$ for 2-3 days. All murine NDPKs suppressed Bax dependent apoptosis. Futher study will be peformed whether Bax-toxicity inhibition was caused by NDP kinase activity or additional function.n.

This paper presents the results of full-scale loading tests performed on 54 passive anchors and 4 group anchored footings grouted to various lengths at several sites in Korea. The test results, the failure mechanisms as well as uplift capacities of rock anchors depend mostly on rock type and quality, embedded fixed length, properties of the discontinuities, and the strength of rebar. Anchors in poor quality rocks generally fail along the grout/rock interfaces when their depths are very shallow (a fixed length of less than 1 m). However, even in such poor rocks, we can induce a more favorable mode of rock pull-up failure by increasing the fixed length of the anchors. On the other hand, anchors in good quality rocks show rock pull-up failures with high uplift resistance even when they are embedded at a shallow depth. Laboratory test results revealed that a form of progressive failure usually occurs starting near the upper surface of the grout, and then progresses downward. The ultimate tendon-grout bond strength was measured from $18{\sim}25%$ of unconfined compressive strength of grout. One of the important findings from these tests is that the measured strains along the corrosion protection sheath were so small that practically the reduction of bond strength by the presence of sheath would be negligible. Based on test results, the main parameters governing the uplift capacity of the rock anchor system were determined. By evaluation of the ultimate uplift capacity of anchor foundations in a wide range of in situ rock masses, rock classification suitable for a transmission tower foundation was developed. Finally, a very simple and economical design procedure is proposed for rock anchor foundations subjected to uplift tensile loads.

In recent years, many Internet giants have begun providing their own content services, which attract online users by offering personalized services based on artificial intelligence technologies. This study investigates the role of two firms' content services within the firms' online service network. We examine the role of Naver Webtoon, which can be characterized as a professional-generated content, within Naver's service portfolio, and that of Google YouTube, which can be characterized as a user-generated content, within Google's service portfolio. Using survey data on viewers' use of the two services, we analyze a valued directed service network, where a node denotes an online service and a relationship between two nodes denotes a sequential use of two services. We found that both Webtoon and YouTube show higher out-degree centrality than in-degree centrality, which implies these content services are more likely to be starting services rather than arriving services within the firms' interactive network. The gap between the out-degree and in-degree centrality of YouTube is much smaller than that of Webtoon. The high centrality of YouTube, a user-generated content service, within the Google service network shows that YouTube's initial role of providing specific-content videos (e.g., entertainment) has expanded into a general search service for users.

This study reviews international discussions about the trade-labor linkage and examines the labor chapters of FTAs enforced by the US and the EU from a comparative perspective. Since early 1990s, starting from the NAFTA, the US has included forceable labor provisions in its FTAs and this trend continues to the TPP which was concluded in October 2015. On the other hand, the EU's labor provisions in its FTAs have been composed of promotional elements on labor rights based on cooperations and dialogues. These different features of labor provisions in the US and European FTAs are mainly due to the motives of the FTAs of the US and the EU respectively as well as their domestic situations with regards to domestic law and institutional set-ups. The coordination of labor provisions involves a long-term institutional as well as regulatory convergence which triggers not only economic but also social changes, compared to a relatively short-term effect of tariff elimination. For Korea which has been a FTA partner country both with the US and the EU, it is significant to keep the different characteristics in the labor provisions in mind, particularly in the process of its implementation. Concerning the implementation of Korea-US FTA, it might be problematic if Korean law and its regulatory practice on labor-management relations do not comply with that of the US. The Korea-EU FTA case can also have an indirect impact on Korea's labor laws since it stipulates in its provisions that both parties should have discussions not only within each government but also with the civil communities including NGOs. Thus, Korea should pay more attention to the true meaning in labor provisions of both FTAs in order to promote its firms to be equipped with the right labor-management system in their operations abroad.

Customer engagement refers to the physical and emotional connection between customers and brands. If the customer's degree of engagement is high, they purchase more, promote more, and show more loyalty. This study suggests the following implications, starting from the assumption that engagement with various service activities in universities can increase loyalty to departments and Universities. In university services, customer engagement plays a important role in strengthening college loyalty after college students are satisfied with university. Although it has an effect on university satisfaction, it can play a big role in increasing the loyalty of marketing goals at a higher level after satisfaction. Among the central factors of university service engagement, it was found that students could increase their department and university loyalty through capacity building and job-related activities for future employment, and among the surrounding factors, friendship activities were a very important factor in department or school loyalty. It can be said that it is of paramount importance to establish a system that can strengthen loyalty through various programs that can build friendships with students. Further research did not verify the moderating effect of service engagement among student groups, but the high-credit group was found to have a very high degree of engagement not only in the central cues but also in the peripheral cues, which is thought to reverse the common sense that high-credit students will be relatively less immersed in the peripheral elements.

This study observed elderly women's adaptation process on separation by death in rural areas through grounded theory approach and developed its entity theory. Participants for this study were 14 elderly women who have lost their husbands in the last 12 months. The study was conducted for 8 months starting January 2010. Each interview per session took 40 to 90 minutes, study notes were taken on site, and recorded contents were transcribed by the researcher which was myself. The research data were collected by in-depth interview and with help of local community's nurses who were in charge of taking care of the participants. The collected data were analyzed by applying Strauss & Corbin's grounded theory (1998). As a result of study, 80 concepts, 28 subcategories, and 12 categories were deducted during open coding process. Adaptation process on separation by death was process of 'finding a way to live alone' which used strategy of 'attempting a make changes in life', and 'embracing the situation' which were influenced by conciliatory conditions of 'degree on economic condition', 'change in health', and 'supporting system' which focuses on phenomenon of 'bearing life alone' which is influenced by context condition of 'marital chemistry of couples during lifetime', and 'the couple's leadership during lifetime' together with casual conditions of 'the fall of wall'. The adaptation process accordance to time flow were divided into 4 steps which were step of 'shock and release of emotions', step of 'longing and resentment', step of 'resignation and acceptance', and step of 'life's restructure'. Above results suggest right directions for welfare for the aged and process of 'finding a way to live alone' for participants by controlling several factors and using intervention strategy, and provided basic data required for developing and applying practical welfare mediation.

This article examines the process of how Daesoon thought keeps its own identity while being practiced as a religion in Korean culture through the perspective of theological hermeneutics of E. Schillebeeckx, a representative theologian in 20th century, especially on the centering of the matter of experience. Schillebeeckx says that an experience is an occurrence of perception by encountering something different from oneself. According to him, 1) the occurrence of perception is premised on a framework or form of interpretation which prescribes experience as the experience in the perceptive dimension. 2) A framework of interpretation is subject to pre-existing system or structure which already has formed a basis to the experience. It consists of various interpretative elements such as social form, general knowledges, various experiences, theoretical models in their society, etc.. 3) The experiences take place in the reflection of contemporary situation, and it is understood by a society, thus making it a social stream. This experience is expressed historically, gains historicity in the process of being handed down from person to person, from generation to generation. In this way, an experience starts to form a tradition. 4) The tradition is a historical stream which gives rise to, admits, and integrates various experiences, religious revelation, and faith etc. In this way, the tradition as a historical stream becomes a field of religious actuality such as revelation, salvation, etc. Conclusively, a religion takes place, is formed, only when it is understood anew by the people who live in that cultural tradition through their languages. The ground Daesoon thought takes place, is formed, is in this way. Daesoon thought takes place in the core of traditional Korean culture, undergoes changes when it encounters the other stream of traditional Korean culture, and the vice versa. Because of this inevitable change, ironically enough, Daesoon thought can maintain its own identity as Daesoon thought, and Korean culture its own identity as Korean culture, avoiding falling into the tertiary which is neither Daesoon thought nor Korean culture. It is in this way that any religion can be in the faithfulness to its starting point to be enriched and transformed in its interaction with the other tradition. At here is the reason Daesoon thought has to have an openness to the changing world.

In 2023, the Cultural Heritage Administration of Korea is transforming a system that has been in existence for the past 60 years. In these circumstances, an increasing recognition of the need for such changes is intended to start the study of the historical context in the conceptual development of cultural heritage. The employment of imported concepts of heritage created the demand for understanding at least the original contexts. Many European concepts have been introduced. In this study, the French Revolution is selected as the starting point for historical research on conceptual development. France opened a new horizon to national heritage since the establishment of the Republic at the end of the 18th century. The French Revolution placed monuments denied by the collapse of the Ancien Regime back into the boundaries of protection. In this process, the Commission des Monuments and the Commission Temporaire des Arts were created. There were limits to conservation activities in the context of the revolution and war. However, it is meaningful in that they established conservation principles with instructions and created new value for looking at monuments. It was pioneering in that it demonstrated the perspective of national heritage. This is significant because the top flow of conceptual development has led to a monument historique, bien culturel, and patrimoine culturel in France. This history provides a universal essence and has great implications for Korea as a divided country

The adoption of smart factories and smart manufacturing as strategies to enhance competitiveness and stimulate growth in the manufacturing sector is vital for a country's future competitiveness and industrial transformation. The government has consistently pursued smart manufacturing innovation policies starting with the Manufacturing Innovation 3.0 strategy in the Ministry of Industry. This study aims to identify policy areas for smart factories and smart manufacturing based on technical standards. Analyzing policy areas at the current stage where the establishment and support of domestic standards aligning with international technical standards are required is crucial. By prioritizing smart manufacturing process areas within the industry, policymakers can make well-informed decisions to advance smart manufacturing without blindly following international standardization in already well-established areas. To achieve this, the study utilizes a hierarchical analysis method including expert interviews and importance-performance analysis for the five major process areas. The findings underscore the importance of proactive participation in standardization for emerging technologies, such as data and security, instead of solely focusing on areas with extensive international standardization. Additionally, policymakers need to consider carbon emissions, energy costs, and global environmental challenges to address international trends in export and digital trade effectively.
