The Mekong which is one of the world's most significant rivers plays an extremely important role to South East Asia. Lying across six riparian countries including China, Myanmar, Thailand, Laos, Cambodia and Vietnam and being a greatly biological and ecological diversity of fishes, the river supports a huge population who living along Mekong Basin River. Therefore, much attention has been focused on the giant Mekong Basin River, particularly, the soil erosion and sedimentation problems which rise critical impacts on irrigation, agriculture, navigation, fisheries and aquatic ecosystem. In fact, there have been many methods to calculate these problems; however, in the case of Mekong, the available data have significant limitations because of large area (about 795 00 km2) and a failure by management agencies to analyze and publish of developing countries in Mekong Basin River. As a result, the Universal Soil Loss Equation (USLE) model in a GIS (Geographic Information System) framework was applied in this study. The USLE factors contain the rainfall erosivity, soil erodibility, slope length, steepness, crop management and conservation practices which are represented by raster layers in GIS environment. In the final step, these factors were multiplied together to estimate the soil erosion rate in the study area by using spatial analyst tool in the ArcGIS 10.2 software. The spatial distribution of soil loss result will be used to support river basin management to find the subtainable management practices by showing the position and amount of soil erosion and sediment load in the dangerous areas during the selected 56- year period from 1952 to 2007.

Objective: <千金方(Qianjinfang)> which documents a great amount of prescription of Acupuncture and moxibustion bikes an important role during the development of acupuncture and moxibustion. Thus, it have given rise us to the research-situation of Tang Dynasty China of previous period. This study was to outline the rules of choosing acupoints as well as the prescriptions of contemporary times in reference with <千金方(Qianjinfang)>, and to discuss the conception of acupuncture and moxibustion in <千金方(Qianjinfang)>. Method: Based on <千金方(Qianjinfang)>, the parameters were categorized to a certain scope, syndromes in different type were classified. Also numbers of acupoints, route of meridians locations, utilities of special acupoints even prescription methods were statistically analyzed in reference with <千金方(Qianjinfang)>. Results & Conclusion: Acupuncture prescription in <千金方(Qianjinfang)> was mostly presented by single acupoint and this was basic prescription of its rule of choosing acupoints. Choosing acupoint for the majority of various diseases started from choosing meridians with the disorder, but no rules for choosing acupoints was clear. There was basically various methods in choosing acupoints, but little were used by Biao-Ii meridian choosing method (表裏經配穴.) In the high frequency of use, wu-shu acupoints was higher used than other specific acupoints (特定穴). While wu-shu acupoints treated the major parts of the diseases, shu-mo acupoints were strictly used on system. Consequently : The theoretical basis originating the choosing rules of the acupoints and prescriptions was shown in <千金方(Qianjinfang)> as representative clinical reference, through which it was valuable to analyze the prescription rule and specificity of the acupoints.

Due to a mistranslation of Sanskrit to Chinese, East Asian Buddhist community misunderstands the original meaning of the fundamental word, 'sachal(寺刹)'. Sanskrit chattra, a parasol on top of a venerated Indian stupa buried with Buddha's sarira, became the symbol of majesty. The Indian stupa was transformed into a pagoda in China, and the highlighted parasol on the summit was transliterated into chaldara(刹多羅), an abbreviation for chal (刹), and finally designated the whole pagoda(塔). Sachal consists with lying low monastery and high-rise pagoda. Tapsa(塔寺), an archaic word of temple, is exactly the same as sachal, because chal means tap, pagoda. However, during the 7th century a Buddhist monk erroneously double-transliterated the Sanskrit 'kshetra,' meaning of land, into the same word as chal, even despite phonetic disaccord. Thereafter, sutra translators followed and copied the error for long centuries. It was the Japanese pioneer scholars that worsen the situation 100 years ago, to publish Sanskrit dictionaries with the errors insisting on phonetic transliteration, though pronunciation of 'kshe-' which is quite different from 'cha-.' Thereafter, upcoming scholars followed their fallacy without any verification. Fallacy of chal, meaning of land, dominates Buddhist community broadly, falling into conviction of collective fixed dogma in East Asia up to now. In the Buddhist community, it is the most important matter to recognize that the same language has become to refer completely different objects due to translation errors. As a research method, searching for corresponding Sanskrit words in translated sutras and dictionaries of Buddhism is predominant. Then, after analyzing the authenticity, the fallacy toward the truth will be corrected.

The 4th Industrial Revolution and the continuous development of Science and Technology have also required a speedy business promotion method in the defense industry. Advanced countries including the United States are already boldly innovating the existing high-cost and long-term acquisition system with the highest priority in weapons development to cope with the military rise of Russia and China. The Ministry of National Defense and the Defense Acquisition Program Administration have also recently introduced a quick acquisition system and are applying it to business promotion. In addition, some small-scale projects and weapons systems are being reorganized so that they can be managed by the units demanding them. After an organizational diagnosis of the Project Acquisition Group by the Ministry of National Defense in 2020, it has been reassigned as a subordinate unit of the Army Logistics Command from a direct unit managed by the Army HQ. As a result, problems such as work conflict or redundancy have been identified. In addition, a system has been implemented to shorten the acquisition period by applying a rapid acquisition program in the field of weapons systems by benchmarking the rapid acquisition program of advanced countries. The force support system project process will also need to introduce such a quick acquisition system. In addition, the Ministry of National Defense is considering ways to delegate some weapon systems to each military, which will then carry out tasks ranging from requirements determination to project management. Accordingly, it is now time to expand the organization for the management of the Army's weapons system acquisition project. Therefore, in this paper, the Army Project Acquisition Group was analyzed on its organization, acquisition procedures, and cooperation systems, with presentations of development plans for each field.

광저우(廣州)를 성도(省都)로 하는 광둥성 주변 남쪽지방은 기원전 221년 진(秦)나라가 통일하기 전까지 지형적으로 교통의 장애를 초래한 오령(五嶺; 다섯 산맥)의 남쪽에 있다하여 '영남(嶺南)'이라 불렸다. 영남의 광둥성 일대는 행정적 독립단위의 남월국(南越國)이라 하였다. 이 지역을 대표하는 '월'이란 한자의 기원은 여기서 비롯되며 월어(광둥어), 월채(광둥요리), 월극(광둥 연극) 등 용어는 지금도 사용된다. 남월국 시대에 번우(番禹)라 불렸던 광저우는 주강(珠江) 삼각주 북부에 일찍이 자리를 잡았다. 이후 청대(淸代)에 이르러 서구 열강에 문호를 개방하게 된 최초의 개항장이 되었다. 오늘날에는 후발 주자인 상하이(上海)에 뒤쳐지기도 했으나 여전히 베이징, 상하이에 이은 세 번째 영향력을 지닌 연해 개방 도시이다. 광저우는 오늘날 세계적인 면방직 공업의 중심일 뿐 아니라 여러 업종의 공업 발달에 박차를 가하고 있는 도시이다. 주변의 홍콩, 마카오, 선전 등과 함께 주강 삼각 경제권 구축에 중요한 역할을 담당하고 있다. 일찍이 화남 최대의 중심도시로 자리 잡은 광저우는 이 지역 정치 경제 문화 등 다방면의 허브인 동시에 북방 정치권에 도전하려는 혁명저항 세력의 중심도시였다. 광저우는 항만으로서 성쇠의 역사를 거쳐 왔지만 지속적인 노력으로 발전하면서 영향력을 지니게 되었다. 그렇지만, 오늘날 역동적으로 발전하는 광저우의 모습 이면에 환경과 질서 등 개선되어야 할 여러 과제를 안고 있다.

Purpose - The competitiveness of logistics in the 21st century rests on ensuring the efficiency and effectiveness of its local hub. While considering entry into a niche market in local logistics, it is pertinent to note that Budapest is emerging as a hub in EU enlargement in Eastern Europe. Big, small, and medium-sized businesses in Korea entered Hungary in the early 1990s since then, there has been a significant increase in Korean presence, of approximately 130 times. This study aimed to identify the key distribution issues that have emerged in relation to Eastern Europe. Research design, data, and methodology - This study indicates that 33 major Korean companies were located in Hungary, which serves as an out post to enter the European marketplace. However, Korea's exports to Hungary have declined (-32.0% in 2012) because of a loss of competitiveness against multinational corporations, due to factors such as the rise in current local distribution costs and wages. Hungary, on the other hand, through diversification and expansion of foreign trade with the non-EU markets, including Korea, is increasing its exports. Strategies of emerging countries are compared and reviewed in this study, by examining the vicissitudes of Hungary's distribution methods. Results - There are issues regarding Hungary's innovative ability. Hungary has a history of low wages and high skilled labor. However, the outflow of high-quality human resources for high-wages has become more extensive, and this underlines concerns that the CEE's trade hub is moving to neighboring countries. After the European financial crisis in 2010, the Hungarian economy is now developing, because of the IMF's measures, and it is being transformed into a trade surplus nation, while regaining distribution volumes rapidly. However, if there is continued lack of investment, the supply chain is weakened and exports decline amidst competition with TNCs or with China's distribution networks. Conclusions - It is necessary to create a new logistics approach for increasing trade between Korea and Hungary. First, Korean small and medium enterprises (SMEs) should build trust by working with advanced Hungarian talent, and they should expand into state-of-the-art fields instead of being confined to traditional sectors. Second, this study focuses on limiting and lowering their high expectations for success according to foreign direct investment (FDI) inflows and the role in the CEE distribution hub Korea should try to strengthen the distribution hub with its centralized population, using better, more highly educated human resources, thereby sustaining more innovative ability. Further, the positive effects of these measures are manifested in enhanced business on both sides of Hungary, namely, the EU and non-EU nations such as Turkey and emerging markets around Europe, and a better engagement in the core placement of culture and industry. For this, Korea can contribute to, and benefit from, a Hungarian logistics center, for adopting the high-tech cluster systems and commercializing distribution technology such as RFID·USN.

To evaluate the safety status of deteriorated segments in a submarine shield tunnel during its service life, a seepage model was established based on a cross-sea shield tunnel project. This model was used to study the migration patterns of erosive ions within the shield segments. Based on these laws, the degree of deterioration of the segments was determined. Using the derived analytical solution, the internal forces within the segments were calculated. Lastly, by applying the formula for calculating safety factors, the variation trends in the safety factors of segments with different degrees of deterioration were obtained. The findings demonstrate that corrosive seawater presents the evolution characteristics of continuous seepage from the outside to the inside of the tunnel. The nearby seepage field shows locally concentrated characteristics when there is leakage at the joint, which causes the seepage field's depth and scope to significantly increase. The chlorine ion content decreases gradually with the increase of the distance from the outer surface of the tunnel. The penetration of erosion ions in the segment is facilitated by the presence of water pressure. The ion content of the entire ring segment lining structure is related in the following order: vault < haunch < springing. The difference in the segment's rate of increase in chlorine ion content decreases as service time increases. Based on the analytical solution calculation, the segment's safety factor drops more when the joint leaks than when its intact, and the change rate between the two states exhibits a general downward trend. The safety factor shows a similar change rule at different water depths and continuously decreases at the same segment position as the water depth increases. The three phases of "sudden drop-rise-stability" are represented by a "spoon-shaped" change rule on the safety factor's change curve. The issue of the poor applicability of indicators in earlier studies is resolved by the analytical solution, which only requires determining the loss degree of the segment lining's effective bearing thickness to calculate the safety factor of any cross-section of the shield tunnel. The analytical solution's computation results, however, have some safety margins and are cautious. The process of establishing the evaluation model indicates that the secondary lining made of molded concrete can also have its safety status assessed using the analytical solution. It is very important for the safe operation of the tunnel and the safety of people's property and has a wide range of applications.
