  • The rice field grasshopper, Oxya chinensis sinuosa (OC), has traditionally been utilized in Korea for various purposes; however, its potential benefits in the context of osteoporosis remain unclear. The results revealed that OC ethanol extract (OCE) significantly inhibited the formation and activity of tartrate-resistant acid phosphatase (TRAP)-positive cells in receptor activator of nuclear factor-κB ligand (RANKL)-stimulated RAW264.7 cells. Furthermore, OCE, at concentrations ranging from 100 to 400 ㎍/mL, demonstrated a dose-dependent reduction in the protein expression of osteoclast-specific markers, including nuclear factor of activated T cell cytoplasmic 1, c-Src, and TRAP, when compared to RANKL stimulation alone. Additionally, OCE significantly inhibited RANKL-induced activation of p38 mitogen-activated protein kinase (MAPK) and c-Jun N-terminal kinase (JNK) but not the activation of extracellular signal-regulated kinase. Collectively, these results indicate that OCE suppresses osteoclastogenesis by attenuating the phosphorylation of p38 MAPK and JNK. Consequently, these findings suggest that OCE holds promise for the prevention of osteoporosis.

  • TNF, a pleiotropic proinflammatory cytokine, is important for protective immunity and immunopathology during Mycobacterium tuberculosis (Mtb) infection, which causes tuberculosis (TB) in humans. TNF is produced primarily by phagocytes in the lungs during the early stages of Mtb infection and performs diverse physiological and pathological functions by binding to its receptors in a context-dependent manner. TNF is essential for granuloma formation, chronic infection prevention, and macrophage recruitment to and activation at the site of infection. In animal models, TNF, in cooperation with chemokines, contributes to the initiation, maintenance, and clearance of mycobacteria in granulomas. Although anti-TNF therapy is effective against immune diseases such as rheumatoid arthritis, it carries the risk of reactivating TB. Furthermore, TNF-associated inflammation contributes to cachexia in patients with TB. This review focuses on the multifaceted role of TNF in the pathogenesis and prevention of TB and underscores the importance of investigating the functions of TNF and its receptors in the establishment of protective immunity against and in the pathology of TB. Such investigations will facilitate the development of therapeutic strategies that target TNF signaling, which makes beneficial and detrimental contributions to the pathogenesis of TB.

  • The socio-economic and environmental systems of world are in turmoil. International conflicts are placed in their geographical context through the integration of maps. Changes in the world political map have often been the outcome of wars and conflicts associated with major geopolitical transitions. We identify five basic types--proto-nationalism, unification nationalism, separation nationalism, liberation nationalism and renewal nationalism. Political leaders in a wide range of contexts have been able to appeal to the nationalist doctrine to justify their actions. In recent years indigenous peoples have found a new voice in their struggle for survival. Although colonial empire's ending followed long and bloody struggles in some places. We really cannot understand the modem world as a whole if we do not understand the dynamic of that part of it which has endured and struggled against colonialism. The patterns of the international conflicting area are divided internal conflict type, mixed conflict type, international conflict type. The formation factors of the international conflicting area are divided ethnic group, religion, colonialism, resource, territory. There has recently been a resurgence of Islam's importance in world affairs. The oil crises of the 1970s gave new international leverage to several Muslim states.

  • The purpose of this study is to grasp the overall policy decision system of sex crime prevention policy and analyze the interaction and pattern of actors in policy formation process. This is a useful way to identify the causes and ways to improve the policy if the sex crime prevention policy fails. As a research method, we used a model of advocacy through case analysis and language network analysis. In the external environment, low reporting of sex offenses, technical improvement and supplement for preventive management, consciousness of victims of sexual crimes, amendment of legislation, and support of the president. The conflicts between the advocacy coalition opposed the strong regulation, the prevention of recidivism, the expansion of the range of objects to be worn, the temporary effect of the system and the retrospective of the bill. As a problem-solving strategy, it was confirmed that the opposing positions of pros and cons of lack of manpower and negligence of management through the extension of the system were acutely opposed. In the context of media reports, this tendency is more likely to be understood as the concern of prevention and management at the central government level to prevent sex crimes. Therefore, although the methods of prevention of sex crimes have been insufficient in the past, it is hoped that this study will be helpful in breaking the link of negative policy vicious cycle.

  • The Altai Humanities Belt connecting Siberia to Central Asia is very important to the history of civilization. It had a huge influence on the formation of an ancient civilization in the Korean Peninsula. Therefore, a variety of studies have been carried out in the field of folklore and anthropology as well as archeology. One of these studies is about the oral epic. The oral epic remains in the form of a unique transmission in Korea, but it wasn't that long ago when it was noted as the component of the Altai Humanities Belt. In that context, some epics from Central Asia, Mongolia, and Siberia were introduced to Korea. This preliminary investigation is conducted to introduce the oral epic Olonkho from Yakutia in Siberia to Korean academia. Although it was revealed recently, Olonkho is highly valued. The epic study has been buried from the Western point of view, but Olonkho is expected to provide a global perspective to the field of epic study. Above all, it contains a very significant clue to a new study because the content and the style of performance are considerably different from those of the West. Additionally, the original form is relatively well preserved. In particular, it explains how human thinking and behaviors have changed in the transition from the mythical age to the heroic age. This change appears in the ethnic history of Yakutia, as well as in the formation process for all Altai countries around the 10th century. Therefore, this preliminary investigation will be a foundation to facilitate the translation of the voluminous Olonkho into Korean, and to conduct full-fledged research on it. In particular, it can motivate a study on the differences and similarities in comparison to the tradition of oral epics between Central Asia and the Korean Peninsula. Furthermore, it will serve as a foundation for the formation of the Altai Humanities Belt.

  • This study adopts the concept of social innovation cluster in which social economy organizations as one of the emerging axes of economic systems operate in collaboration with government agencies, investment institutions, intermediate supporting organizations and non-profit organizations, and investigates how the clusters of this kind grow in the context of the Korean socio-economic situation for the cases of Seongdong-gu and Eunpyeong-gu in Seoul, Korea. For this purpose, it has identified the actors of the clusters and their internal relations, and analyzed the process of cluster formation. A social network analysis of the partnerships between the actors has shown that Seongdong-gu has more diversified types of the network participation of universities, global networks and investment institutions than Eunpyeong-gu. It is interpreted that this pattern has resulted from the domination of private organizations in the former area, which is also confirmed by in-depth interviews with persons involved in the clusters. Although the facets of social innovation clusters are manifested in both areas, even in their initial stage, such factors as linkages between industrial actors and convergence with other clusters, which appear in the maturing stage of cluster formation, has yet to be found. It is suggested that the sustainable growth of social innovation clusters should be accompanied by information sharing and cooperation between the two areas on the future orientation of development.

  • This article not only theoretically explores the necessity and effect of constructive minilateralism and subregionalism in Northeast Asia, but also delves into a series of practical solutions from viewpoint of seeking common ground while reserving differences in this region. The main contents are as follows: First, the various obstacles that hinder the formation of regionalism, subregionalism and minilateralism in the Northeast Asia are discussed. That is to say, geopolitical realism, My Country First ideology, exclusive nationalism in the socio-historical context, and North Korea's latest provocations, etc. Second, this article explores the philosophy and basic principles of realizing Northeast Asia regionalism and minilateralism. Third, in the 21st century, Northeast Asia becomes the center of the world. It examines the core points, controversial focus and platform for building sub regionalism in the region. Finally, based on the institutional platform such as minilateralism and sub regionalism, the various ideas and practical plans of cross-border cooperation among major countries in Northeast Asia were discussed. Because there are a lot of obstacles, so first of all it is more appropriate to promote economic or functional minilateralism or sub regionalism than multilateral cooperation. In order to promote the formation of regionalism and minilateralism in Northeast Asia, the issues to be considered are as follows: First, for the sake of leading regional solidarity and minilateral economic cooperation, it is advisable for China, as a regional economic power, to implement a stable and responsible diplomacy. Secondly, regional solidarity based on credible politics and security should be promoted for a long time beyond the level of economic cooperation. Third, the primary prerequisite for the realization of Northeast Asian regionalism is that in the process of denuclearization of North Korea, the stability and peace mechanism of the Korean Peninsula should be established. Fourth, with the continued hegemonic competition between the United States and China in Northeast Asia, under the circumstance that countries in the region are pushed into so-called "East Asian Paradox", it is profoundly important for them to consider transition from the hostile relationship as the "Thucydides trap" to the order of "coexistence" in which competition and cooperation run side by side, and the two countries should explore a conversion plan for the foreign policy line. This mutual cooperation and peaceful coexistence of the US-China relationship will create a friendly atmosphere for the formation of regionalism in Northeast Asia. In the future, the cooperation of minilateralism in Northeast Asia will break the existing conflict between the maritime forces and the continental forces in order to promote peace. And along with the philosophy that "peace is economy", recent policies of common prosperity as the framework, such as China's "Belt and Road Initiative", North Korea's "Special Zone and Development Zone Policy", Russia's "New Eastern Policy", Japan's participation in the Belt and Road Initiative and South Korea's The "Korean Peninsula New Economy Map" are organically linked and it should promote the so-called "networked regionalism".

The Origin of Records and Archives in the United States and the Formation of Archival System: Focusing on the Period from the Early 17th Century to the Mid 20th (미국의 기록(records) 및 아카이브즈(archives)의 역사적 기원과 관리·보존의 역사 17세기 초부터 20세기 중반까지를 중심으로)

  • The National Archives and Records Administration (NARA) is a relatively quiet latecomer to the traditional archives of the Western world. Although the United States lacks a long history of organized public records·archives management, it has developed a modern system optimized for the American historical context. This system focuses on the systematic management and preservation of the vast amount of modern records produced and collected during the tumultuous 20th century. As a result, NARA has established a modern archival system that is optimized for the American historical context. The U.S. public records·archives management system is based on the principle that records·archives are the property of the American people and belong to the public. This concept originated during the British colonial era when records were used to safeguard the rights of the colonies as self-governing citizens. For Americans, records and archives have long been a symbol of the nation's identity, serving as a means of protecting individual freedoms, rights, and democracy throughout the country's history. It is natural, therefore, that American life and history should be documented, and that the recorded past should be managed and preserved for the nation's present and future. The public records·archives management system in the United States is the result of a convergence of theories, practices, lessons learned, and ideas that have been shaped by the country's history, philosophies, and values about records, and its unique experience with records management. This paper traces the origins of records and archives in the United States in a historical context to understand the organic relationship between American life and records. It examines the process of forming a modern public records management system that is both uniquely American and universal to the American context without falling into the two forms of traditions that reflect the uniqueness of American history.

  • Donghak's teaching, In-nae-cheon, means "humans are divine." It is said, "When humans were formed, God's blessing was required for their formation." Donghak's Sincerity, Respectfulness, and Faithfulness is based on believing in God, respecting God, and practicing His teachings with utmost sincerity. These are key to implementing In-nae-cheon. On the other hand, the Three Essential Attitudes in Daesoon Thought, also Sincerity, Respectfulness, and Faithfulness, appear in a religious sense. These can be distinguished from Sincerity, Respectfulness, and Faithfulness in the Donghak moral sense. Sincerity, Respectfulness, and Faithfulness in the context of the Three Essential Attitudes in Daesoon Thought goes beyond moral awareness, and calls for belief in God as the Absolute. Accordingly, Sincerity, Respectfulness, and Faithfulness in this context, that of Daesoon Thought, aims at the realization of an Earthly Paradise wherein God's will can be achieved. Humans participating in the construction of Earthly Paradise value the practice of Sincerity, Respectfulness, and Faithfulness. In Daesoon Thought, it is said that when one exerts sincerity, respect, and faith in God (Sangje), all the blessings and fortune of the Later World, even those of longevity, will be endowed through transformation via effortless action (無爲而化). Accordingly, Sincerity, Respectfulness, and Faithfulness in the context of the Three Essential Attitudes in Daesoon Thought is based on God's descent into the world and His Reordering Works of Heaven and Earth (天地公事). This is a religious faith that worships Sangje and is based on the doctrinal dimension of 'guarding against self-deception (毋自欺)' and the philosophical dimension of Sincerity, Respectfulness, and Faithfulness in the context of the Three Essential Attitudes in Daesoon Thought. Donghak's In-nae-cheon and the Three Essential Attitudes in Daesoon Thought can be compared and analyzed. Therefore, in order to clearly compare and analyze the moral significance of Donghak history and the religious meaning of Daesoon Thought, Roderick Ninian Smart's method of religious phenomenology can be actively used. In this way, the ethical and legal dimensions of Donghak's In-nae-cheon and the doctrinal and philosophical dimensions of the Three Essential Attitudes in Daesoon Thought can be compared and analyzed. From this style of research, it can be concluded that the realization of commonly shared spirituality can be an opportunity for greater human dignity.

  • The cultural values of the traditional way and the current cultural values of young people are very different, and the rejection of cross-cultural contact is greatly reduced because Korean young people easily accommodate other cultures of the US, Europe or Asia. At present, the cultural values of the traditional way and the current cultural values of young people are very different, and the youthfulness of Korean young people easily accepts other cultures of the US, Europe or Asia, so the resistance to cross - cultural contact is greatly reduced. The purpose of this study is to find out how the younger Korean youths are forming the change of the foreign culture and how the negotiation will proceed according to the formation of these cultures. The results of the analysis show that Korean young people have collectivism cultural rights and that they are consistent with the previous research that there is tendency to avoid uncertainty. On the other hand, there is a tendency of opposition as a result of the empirical analysis that the Koreans have a strong orientation, a high power interval, and strong masculinity. Also, as a result of analyzing the changes in Korean culture that belongs to the high background culture, Korean young people tend to be centered in the past and decision makers tend to decide by the chief executive. On the other hand, Korean young people were denied all the verifiable cultural attributes that cultural properties and communication that maintain openness to share space exposures and office space are non - verbal, tacit communication and time observation are very long and uncertain.
