This paper studies economic growth convergence conditioning on various characteristics of East Asian countries. Our findings suggest that when trade openness is conditioned in addition to human capital and investment, the economic growth rates for East Asian countries converge faster than when human capital and investment alone are considered. In particular, while Northeast Asian countries exhibit absolute economic growth convergence as well as economic growth convergence conditioned on trade openness, Southeast Asian countries show only economic growth convergence conditioned on trade openness. Analysis of policy implications based on the results of the first East Asian countries' high dependence on foreign trade, trade openness in the convergence of economic growth has had a significant positive effect. Second, in order to establish a regional economic integration in East Asia, Northeast Asia and Southeast Asia, the country's economic growth is necessary to reduce the gap.

Satellite images can be integrated into a crop model to strengthen the advantages of each technique for crop monitoring and to compensate for weaknesses of each other, which can be systematically applied for monitoring inaccessible croplands. The objective of this study was to outline the productivity of paddy rice based on simulation of the yield of all paddy fields in North Korea, using a grid crop model combined with optical satellite imagery. The grid GRAMI-rice model was used to simulate paddy rice yields for inaccessible North Korea based on the bidirectional reflectance distribution function-adjusted vegetation indices (VIs) and the solar insolation. VIs and solar insolation for the model simulation were obtained from the Geostationary Ocean Color Imager (GOCI) and the Meteorological Imager (MI) sensors of the Communication Ocean and Meteorological Satellite (COMS). Reanalysis data of air temperature were achieved from the Korea Local Analysis and Prediction System (KLAPS). Study results showed that the yields of paddy rice were reproduced with a statistically significant range of accuracy. The regional characteristics of crops for all of the sites in North Korea were successfully defined into four clusters through a spatial analysis using the K-means clustering approach. The current study has demonstrated the potential effectiveness of characterization of crop productivity based on incorporation of a crop model with satellite images, which is a proven consistent technique for monitoring of crop productivity in inaccessible regions.

The purpose of this study is to analyze the problems facing the youth soccer league(i-league) and present their development directions. The study method used focus group interviews. The results of the study are summarized into three: First, promotion and regional league operation were highlighted as problems of i-League and the solution was the unification system of the Korean Olympic Committee(KOC) and the Korea Football Association(KFA), and the operation of each region by itself. Second, issues resulting from the integration of youth club league and i-league were revealed as level differences by teams and leak of the motivation for winning. Operation of the elevating system was proposed as a solution, and such as fare play team award, voluntary activity team award will derive important virtues for youth. Third, KOC and KFA need additional support for various environments and administrative areas such as facility security, training for leaders and officials, and registration of players.

Southeast Asia witnessed a paradox of political stagnation and economic development in 2017. The 'dual order' of security dependence on America and economic dependence on China was sustained in East Asia. In this regard, Southeast Asia of two faces was quite similar to broader East Asia. On one hand, the old socialist group with totalitarian nostalgia lurked in the buffer zone between totalitarianism and authoritarianism, while the original capitalist group under democratic disguise roamed in the gray zone between authoritarianism and democracy. On the other, the old socialist group with the legacy of the planned economy succumbed to the temptation of the Beijing Consensus on state capitalism, while the original capitalist group with the myth of the market economy was exposed to the pressure of the Washington Consensus on liberal capitalism. The ASEAN Community representing the regional integration of Southeast Asia was caught in the strategic predicament of a looming 'new cold war' between the continental and maritime powers.

This study aimed to maximize the potential of fluorescence 3D excitation-emission matrix (EEM) for predicting the trihalomethane formation potential (THMFP) of DOM with various sources. Fluorescence spectroscopy is a useful tool for characterizing dissolved organic matter (DOM). In this study, differential spectroscopy was applied to EEM for the prediction of THMFP, in which the difference between the EEM before and after chlorination was taken into account to obtain the differential EEM (DEEM). For characterization of the original EEM or the DEEM, the maximum intensities of several different fluorescence regions in EEM, fluorescence EEM regional integration (FRI), and humification index (HIX) were calculated and used for the surrogates for THMFP prediction. After chlorination, the fluorescence intensity decreased by 77% to 93%. In leaf-derived and effluent DOM, there was a significant decrease in the protein-like peak, while a more pronounced decrease was observed in the humic-like peak of river DOM. In general, leaf-derived and effluent DOM exhibited a relatively lower THMFP than the river DOM. Our results were consistent with the high correlations between humic-like fluorescence and THMFP previously reported. In this study, HIX (r= 0.815, p<0.001), FRI region V (r=0.727, p<0.001), humic-like peak (r= 0.827, p<0.001) from DEEM presented very high correlations with THMF P. When the humic-like peak intensity was converted to a logarithmic scale, a higher correlation was obtained (r= 0.928, p<0.001). This finding suggests that the humic-like peak in DEEM can serve as a universal predictor for THM formation of DOM with various origins.

This article focuses on the period from the beginning of Twentieth, the period commonly regarded as the Enlightenment Period in Korea. Questioning Daehan-Sin-Gygi( 問答大韓新地誌) textbook consists of contents of physical geography aimed at rational and objective perception of the nature, within the frame of Sirak(實學) and Progressive Thoughts. In terms of contents organization, there are too wide range of facts and knowledge covered, with mechanical imitation of statement style of systematic and regional approach. Particularly, Geography textbook in this period attached greater importance to contents of physical geography than any other times. It is possible to conclude that real outcomes of geography education at the time contributed significantly to enlightenment of people and integration of the society. I consider that statement style of question-response used at the time is very worth-while.

In this paper, we design and implement the Walking Life Festival application, which is based on the Android platform and provides information about domestic travel destinations and regional festivals in South Korea. This application utilizes various sensors found in smartphones, including the Step Counter sensor, Step Detector sensor, Acceleration sensor, and GPS sensor. Additionally, it makes use of Google Map API and Public Open API to offer information about domestic travel destinations and local festivals. The application also incorporates an automatic login feature using the Shared Preference API. When storing login information in the database, it encrypts the input plaintext data using a hash algorithm. For Google Maps integration, it creates objects using the Google.maps.LatLngBounds() method and extends the location information through the extends method. Furthermore, this application contributes to the activation of the domestic tourism industry by notifying users about the timing of local festivals related to domestic travel destinations, thus increasing their opportunities to participate in these festivals.

A prerequisite for a lasting ceasefire is the emergence of a prevailing view in Moscow and Kyiv that the fighting has reached a hurting stalemate. In sum, they both lose more through continuing warfare than by a ceasefire. This study applies social identity dynamics of nationalism to this escalatory conflict. It generates findings that imply that China as a third-party great power intervening mediator can potentially play a pivotal role. Shifting the respective prevailing views in Moscow and Kyiv of their interaction from a zero-sum foundation requires proffering powerful economic and political third-party incentives. Effective inducement would facilitate national defense, development and prestige for Moscow as well as Kyiv. China arguably has the underutilized potential power capabilities necessary to alter the respective prevailing views of strategic relationships among the great powers within Moscow, Brussels and Washington. A prerequisite for success in striving effectively towards this strategic goal is cooperation with the Beijing despite skepticism from Washington. This study utilizes a process tracing methodological approach. It highlights that the foundations of the Russo-Ukraine war lie in the institutionalization within Euro-Atlantic integration of the Cold War assumption that the USSR was an imperialist revisionist actor. Russia is the USSR's successor state. Moscow's prevailing view is that Russian national self-determination was unjustly circumscribed in the multinational Soviet totalitarian Communist system. The Euro-Atlantic community is perceived as a neocolonial imperial threat by allying with post-1991 Ukrainian nationalism at Russia's expense. The study finds that acknowledging Eurasian regional multipolarity is necessary, if not sufficient, to coopt Beijing into a global political stabilization strategy. It functionally aims to promote international balancing to lessen potentials for horizontal as well as vertical escalation of the Russo-Ukrainian conflict.

While in high-income countries the development of digital technology began in the 1970s, in low- and middle-income countries it began in the 1990s and even after 2005, due to the political regime that constrained economic development and innovation. At the same time, there are no studies of the relationship between technological development and structural changes through innovation in low- and middle-income countries. The article aims to quantify the relationship of the introduction of digital technologies on innovation, structural transformation of low- and middle-income economies. The industrial-agrarian economy of Uzbekistan with an authoritarian regime is in a state of transition to a market economy, while in Ukraine, there are active processes of Europeanization and integration into the EU. Ukraine's economy is commodity-based (the export of raw materials of industries and the agricultural sector in developed countries predominates) and industrial-agrarian. Digital technologies and the service sector are little developed in Uzbekistan. On the other hand, Ukraine has a more developed ICT sector. Uzbekistan is gradually undergoing an innovative and structural transformation of the economy: the productivity of the agricultural, industrial, and service sectors is growing, but the ICT sector is virtually undeveloped. In comparison, in Ukraine, there are no significant structural transformations due to a significant drop in productivity of the industrial sector, with stable growth of productivity of the agricultural sector due to technology and a slight increase in productivity of the service sector. It is revealed that Ukraine and Uzbekistan have undergone structural transformations of the economy in favor of the service sector, while the agricultural and industrial sectors produce less and less. If Uzbekistan remains the industrial-agrarian country with an aggregate share of the added value of these sectors 59% in 2019, Ukraine transits to the post-industrial type of economy where the added value of the service sector in GDP grows (55% compared to agrarian and industrial sectors at 42%).
