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.

이 연구는 한국전쟁(6 25전쟁) 기간 북한이 남한에서 시행한 언론정책과 그에 따른 주요 언론활동을 고찰했다. 또한 언론활동의 구체적인 내용과 특성을 이해하기 위해 북한이 남한에서 발행한 대표적인 두 신문 $\ulcorner$조선인민보$\lrcorner$와 $\ulcorner$해방일보$\lrcorner$에 대해 분석했다. 북한은 서울을 점령한 그날부터 방송을 운영했고 바로 신문을 창간했다. 이어 북한과 소련의 신문과 정기간행물을 보급하기 시작했고 영화를 상영했으며, 주간지를 창간하는 등 적극적으로 언론활동을 전개했다. 이와 같이 여러 매체들이 출현했으나 그 목표는 모두 같았다. 성공적인 전쟁수행과 점령한 남한지역에 북한식 제도와 법을 도입하여 공산주의체제로 만들고자하는 김일성의 계획을 지원하는 것이었다. 두 신문은 권력의 대행자로서 비현실적 낙관주의를 바탕으로 선동적 거짓말을 과장해서 보도한 수단적 존재였다. 그리하여 당시 남한의 독자들을 사상적으로 동원하고, 그들의 시각과 행동을 주조하려 한 것이다. 그러나 두 신문을 비롯한 한국전쟁 기간 북한이 남한에서 운영한 언론매체들은 수용자인 남한 주민들로부터 신뢰와 호응을 받지 못했다. 대부분의 남한주민들은 북한 언론매체의 일방적이며 진실성이 결여된 끊임없는 선전과 선동, 이데올로기적 교화에 피곤해했다. 따라서 한국전쟁 개시 이후 북한이 남한에서 전개한 언론활동은 그들이 목표로 한 남한 주민들을 사상적으로 조직하고 동원하는 데 많은 한계가 있었다고 평가할 수 있을 것이다.

This study analyzes the combat case involving military drones during the Azerbaijan-Armenian War, which erupted on September 27, 2020. The background of the war revealed that Azerbaijan extensively and aggressively employed offensive drones, which played a decisive role in reshaping the dynamics of the battlefield. Despite Azerbaijan's GDP of $4.639, which corresponds to the level of a developing country, and its 64th rank in global military strength, the country boldly allocated a significant portion of its budget to develop its drone capabilities in preparation for the war. As a result, Azerbaijan effectively utilized offensive drones acquired from Turkey and Israel to neutralize hundreds of tanks, armored vehicles, artillery units, and air defense systems. The purpose of this study is to examine this context and explore how our Korean military organization can enhance its combat capabilities by developing a drone combat system, thereby enabling an effective response posture against multifaceted threats.
