  • Among lots of sabermetric statistics for baseball batters' ability, the wins above replacement (WAR) is the most popular statistic in MLB. However, there exists a difficulty applying WAR to KBO, since KBO data do not have position adjustment, league adjustment and park factor which are essential in calculating WAR. In this paper, using five statistics for both KBO and MLB qualified batters, we propose hitting ability index (HAI), an alternative sabermetric indices to represent batters' ability. Comparing HAI with WAR of MLB batters, we evaluate the validity of HAI and then applied HAI to 2015 KBO data in which HAI is analyzed statistically with respect to different teams, ages, and positions. Moreover, the linear relationship between KBO batter's HAI and their annual salary is discussed. Grouping 46 KBO batters based on confidence region of the regression model for annual salary, we also statistically investigate batter's annual salary in these groups with respect to several factors.

  • This article examines the cases of archive development by research institutions for overseas Korean studies from the perspective of documenting the locality and explores development plans. The study investigates the impact of the solidarity between overseas Korean studies institutions and Korea-related communities in the region on the expansion of archives and the practice of locality documentation, using the case of the Korean War Archive Collection at the University of Hawai'i at Mānoa Library. For this, it reexamines the implications of locality and locality documentation. In addition, it discusses the methods of Korean studies locality documentation emerging abroad, such as the locality where the two geographical areas of Korea and Hawaii are fused. Since 2023, the University of Hawai'i at Mānoa Library has been forming a network with the Korean War Veterans Association Hawaii Chapter 1 (KWVA) to collect and archive materials related to the Korean War. This is a case where the relationship between the archivists and the donor community has been developed to practice documenting the locality regarding Korean studies abroad. It proposes locality documentation as a way to expand archives in overseas Korean studies institutions that inevitably rely on the collection of records and discusses the importance of solidarity with Korea-related local communities. Finally, it shares the role of the record management subject and the implications found through the case.

  • This article will analyze and forecast important variables and dynamics in global power politics after the war in Ukraine. It tries to use several perspectives to analyze international relations, particularly liberal internationalism and structural realism. In short, core variables are as follows; First, how is the US-led liberal international order and globalization being adjusted? Second, how will the U.S.-China strategic competition, which is the biggest and structural variable, cause changes in the international order in the future? The third variable, how stable are Sino-Russia relations in the context of a structuring U.S.-China-Russia strategic new triangle? Fourth, to what extent will third middle hedging states outside the U.S. and China be able to exercise strategic autonomy in the face of multipolarization? To summarize, the first of these four variables is the largest basic variable at the global political and economic level in terms of its impact on the international community, and it has been led by the United States. The second variable, in terms of actors, seems to be the most influential structural variable in global competition, and the US-China strategic competition is likely to be a long game. Thus the world will not be able to escape the influence of the competition between the two global powers. For South Korea, this second variable is probably the biggest external variable and dilemma. The third variable, the stability of Sino-Russia relations, determines balance of global power in the 21st century. The U.S.-China-Russia strategic new triangle, as seen in the current war in Ukraine, will operate as the greatest power variable in not only global power competition but also changes in the international order. Just as the U.S. is eager for a Sino-Russia fragmentation strategy, such as a Tito-style wedge policy to manage balance of power in the early years of the Cold War, it needs a reverse Kissinger strategy to reset the U.S.-Russia relationship, in order to push for a Sino-Russia splitting in the 21st century. But with the war in Ukraine, it seems that this fragmentation strategy has already been broken. In the context of Northeast Asia, whether or not the stability of Sino-Russia relations depends not only on the United States, but also on the Korean Peninsula. Finally, the fourth variable is a dependent variable that emerged as a result of the interaction of the above three variables, but simultaneously it remains to be seen that this variable is likely to act as the most dynamic and independent variable that can promote multilateralism, multipolarization, and pan-regionalism of the global international community in the future. Taking into account these four variables together, we can make an outlook on the change in the international order.

  • Type 1 diabetes mellitus (T1DM) is a pathological condition associated with osteopenia. $WNT/{\beta}$-catenin signaling is implicated in this process. Trabecular and cortical bone respond differently to $WNT/{\beta}$-catenin signaling in healthy mice. We investigated whether this signaling has different effects on trabecular and cortical bone in T1DM. We first established a streptozotocin-induced T1DM mouse model and then constitutively activated ${\beta}$-catenin in osteoblasts in the setting of T1DM (T1-CA). The extent of bone loss was greater in trabecular bone than that in cortical bone in T1DM mice, and this difference was consistent with the reduction in the expression of ${\beta}$-catenin signaling in the two bone compartments. Further experiments demonstrated that in T1DM mice, trabecular bone showed lower levels of insulin-like growth factor-1 receptor (IGF-1R) than the levels in cortical bone, leading to lower $WNT/{\beta}$-catenin signaling activity through the inhibition of the IGF-1R/Akt/glycogen synthase kinase $3{\beta}$ ($GSK3{\beta}$) pathway. After ${\beta}$-catenin was activated in T1-CA mice, the bone mass and bone strength increased to substantially greater extents in trabecular bone than those in cortical bone. In addition, the cortical bone of the T1-CA mice displayed an unexpected increase in bone porosity, with increased bone resorption. The downregulated expression of WNT16 might be responsible for these cortical bone changes. In conclusion, we found that although the activation of $WNT/{\beta}$-catenin signaling increased the trabecular bone mass and bone strength in T1DM mice, it also increased the cortical bone porosity, impairing the bone strength. These findings should be considered in the future treatment of T1DM-related osteopenia.

  • Early 20th century Singapore was faced with the problem of overcrowding. The attendant problems of a rapid increase in population density, namely the lack of proper housing and sanitation, resulted in the issue of an appropriate residential environment emerging as an important task in urban planning. It was necessary to construct housing estates in order to solve this issue. At that time, the British colonial government attempted to transplant modern technology into the construction process of a residential complex system. However, Singapore's climate and traditional lifestyle made it impossible to apply the British modern system in a straightforward manner, and in the process, a number of transformations emerged. With a specific focus on the Tiong Bahru estate, one of Singapore's representative public housing projects, from the 1930s through the 1950s, this study intends to look at the way in which such residential estates were assimilated into local surroundings, and the effect of the transplantation of British concepts of modern housing theory. Therefore, the study is divided into an examination of the estate both before and after the turning point of World War II. This study confirms that the difference between the pre-war and post-war planning strategies for the Tiong Bahru estate were made according to the concept of 'open space.'

  • Objectives: This study investigated the prevalence and characteristics of comorbid conditions in patients exposed to ionizing radiation and those who were involved in the Soviet-Afghan war. Methods: This study analyzed the frequency and spectrum of morbidity and comorbidity in patients over a long-term period (30-35 years) following exposure to ionizing radiation at the Semipalatinsk nuclear test site or the Chornobyl nuclear power plant, and among participants of the Soviet-Afghan war. A cohort study, both prospective and retrospective, was conducted on 675 patients who underwent comprehensive examinations. Results: Numerical data were analyzed using the Statistica 6 program. The results are presented as the mean±standard deviation, median, and interquartile range (25-75th percentiles). The statistical significance of between-group differences was assessed using the Student t-test and Pearson chi-square test. A p-value of less than 0.05 was considered statistically significant. We found a high prevalence of cardiovascular diseases, including hypertension (55.0%) and cardiac ischemia (32.9%); these rates exceeded the average for this age group in the general population. Conclusions: The cumulative impact of causal occupational, environmental, and ultra-high stress factors in the combat zone in participants of the Soviet-Afghan war, along with common conventional factors, contributed to the formation of a specific comorbidity structure. This necessitates a rational approach to identifying early predictors of cardiovascular events and central nervous system disorders, as well as pathognomonic clinical symptoms in this patient cohort. It also underscores the importance of selecting suitable methods and strategies for implementing treatment and prevention measures.

  • Purpose of the War history's study is getting instruction by analyzing victory and defeat factor. This study is studied by qualitative form in war study mainly. In case recording literature is full, victory and defeat factor analysis is easy, but occasionally definite analysis that recording literature is feeble is difficult. Also, when it is battle result that escape common sense, about victory and defeat factor, various estimations are brought. As such example, there is Myeong-Ryang sea-battle at Japanese Invasion of Korea in 1592 and Korea(Cho-Sun) naval forces did big victory in 13 vs. 133 numerical inferiorities. This study presented method of study that using agent based simulation model for quantitative analysis of these victory and defeat factor.

  • This study aimed to analyze the commemoration characteristics of the national war memorials made by the United States, the Union of Soviet Socialist Republics(the Soviet Union), and Germany that participated in World War II(WW II). The results of the study are summarized as follows. First, the creation of the WW II memorials of the United States, the Soviet Union, and Germany aimed to commemorate the dead and victims. By country, the United States promoted unity and victory with representing the just and great cause for freedom, and the communist Soviet Union emphasized the Great Patriotic War that defeated fascist Nazi Germany. On the other hand, Germany, which had difficulty in national commemoration, cherish the victims of the war and aimed for peace. Second, WW II memorials were located in places of national significance such as national representative places and battlefields, and in Germany they were built in church cemeteries and public cemeteries. In addition, it showed concise and moderate aesthetic characteristics with a symmetrical and formal form centered on the axis of space in memorials. Third, the United States and the Soviet Union commonly visualized the appearance of war on the memorial wall. By country, the United States engraved sacrifice and dedication for freedom, and differently the Soviet Union and East Germany engraved messages promoting communist ideology as memorial texts. As for landscape details and sculpture, the United States emphasized national unity through eagles symbolizing the country and a colonnade representing each state and territory, and the Soviet Union set up a communist-style soldier sculpture. The United States and the Soviet Union, both countries used sculptures and laurels that symbolize victory, but in Germany, the statues of a fallen soldiers were installed in the memorial. Politically, the United States commemorated the victory of the war and also promoted unity, and the Soviet Union emphasized the Great Patriotic War and promoted communism. As the United States, the Soviet Union, and the Germans believed in Christianity universally, Christian symbols such as the crucifixion, the church, and the statue of Evita were often used. Further study will be required to establish national identity at memorials and advanced commemorative culture in Korea.
