This paper deals with the question of the origin of polo. Although it is a sport that has been mainly active in the West since the nineteenthcentury, it is well known that British troops in the northern part of Pakistan learned about the sport from the local people there. Most agree that the origin of polo is Iran. However, in this paper, rather than specifying a specific area as the birthplace of polo, it is argued that polo was a cultural phenomenon commonly found on the Silk Road. This is based on the fact that polo has been known for centuries in China, the Korean Peninsula, and Japan, as well as throughout Iran, northern India, Tibet, Central Asia, and the Uighur Autonomous Region. Yet, the transmission of polo cannot be traced chronologically according to the supposed propagation route. This cultural phenomenon has changed over a long period of time according to the local environment, and the change was caused by mutual exchanges, not by one party. Therefore, there are limitations to interpreting cultural phenomena linearly. Thus, the origin of polo could also be identified with another area, namely Baltistan in modern day Pakistan, instead of Iran. These results support the argument that to understand Silk Road civilization, a process-centric approach based on 'exchanges', not a method of exploring archetypes to find 'the place of origin', should be utilized. Polo is undoubtedly an important cultural artifact with which to read the Silk Road as a cultural belt complex, as well as an example of the common culture created by the whole Silk Road.

송대는 정치 경제 그리고 문화를 통틀어 중국 역사상의 중요한 전환기이며, 정치제도와 경제체제, 사상의식과 문화특징 등 모든 면에서 중요한 변혁이 있었다. 이러한 변화는 대부분 당대(唐代) 후기에 시작되어 북송시기에 완성되었다. 물론 그 발전이 비교적 긴 과정을 거쳤지만, 그 변화는 거대하고도 본질적인 것이었다. 때문에 각 분야의 제도에 비교적 강력하게 나타났으며, 그 가운데 도성의 조직체계와 특징에서 더욱 뚜렷하게 드러난다. 송대 정치제도 변화의 핵심은 동한(東漢) 이래 형성된 사족문벌제도(士族門閥制度)가 철저하게 붕괴되고 황제를 중심으로 긴밀하고 완벽한 관료체제가 형성되었다는 것으로, 송대는 고도로 집중된 중앙집권체제를 이루었다. 이는 대략 재상(宰相)집단의 형성, 중앙정권의 권력분화, 황제의 지방통제 강화, 관리선출과 과거제도의 개선 등의 내용을 포괄한다. 이로부터 황제는 전 분야에 뻗치는 막강한 권력을 쥐게 되었으며, 각종 제도의 제정은 황제의 권력과 지위 강화라는 목적으로 직결되지 않는 것이 없었다. 동시에 송대는 경제가 고도로 발전한 시기로, 농촌에서는 조전제(租田制)를 핵심으로 하는 생산구조가 형성되어 농업발전이 극대화되었고, 만당(晩唐) 시기부터 농업과 수공업 기술의 발전에 힘입어 상품경제의 발전이 가속화되기 시작하여, 송대에 이르러서는 상업의 사회경제적 위상이 크게 향상되고 나아가 도시경제체계를 형성하게 되었다. 정치제도의 변화와 경제적 발전이 각종 도시제도의 형성에 영향을 미친 것이다. 이 글에서는 1980년대 초기 이후로 북송 동경 변량성(東京 지금의 河南省 開封市)에 대해 진행된 고고학적 작업을 정리하고, 또한 그 성과에 근거하여 북송 동경 변량성의 특징을 간략하게 종합해 보고자 한다.

Drought is a recurrent natural hazard in Bangladesh. It has significant impacts on agriculture, environment, and society. Well-timed information on the onset, extent, intensity, duration, and impacts of drought can mitigate the potential drought-related losses. Thus, drought characteristics need to be explained in terms of frequency, severity, and duration. This paper aims to characterize the spatial and temporal pattern of meteorological drought using EDI and illustrated drought severity over Bangladesh. Twenty-seven (27) station-based daily rainfall data for the study period of 1981-2015 were used to calculate the EDI values over Bangladesh. The evaluation of EDI is conducted for 4 sub-regions over the country to confirm the historical drought record-developed at the regional scale. The finding shows that on average, the frequency of severe to extreme drought is approximately 0.7 events per year. As a result of the regional analysis, most of the recorded historical drought events were successfully detected during the study period. Additionally, the seasonal analysis showed that the extreme droughts were frequently hit in northwestern, middle portion of the eastern and small portion of central parts of Bangladesh during the Kharif(wet) and Rabi(dry) seasons. The severe drought was affected recurrently in the central and northern regions of the country during all cropping seasons. The study also points out that the northern, south-western and central regions in Bangladesh are comparatively vulnerable to both extreme and severe drought event. The study showed that EDI would be a useful tool to identify the drought-prone area and time and potentially applicable to the climate change-induced drought evolution monitoring at regional to the national level in Bangladesh. The outcome of the present study can be used in taking anticipatory strategies to mitigate the drought damages on agricultural production as well as human sufferings in drought-prone areas of Bangladesh.

The Okdong Fault is situated in Okdong-Hamchang area, the central part of Korea. The area consists of Precambrian gneisses and granitoids, Paleozoic clastic and carbonate rocks, and Mesozoic clastic rocks and igneous intrusives. The Okdong Fault is situated along contact boundary between the lowermost Cambrian Basal Quartzite and Precambrian basements. Mylonites occur as narrow zone which is extended over 100km and is restricted to within 10m-30m along the Okdong Fault. The main features of mylonites are quartz mylonite derived from Cambrian Basal Quartzite and mylonitic granitoids from Precambrian granitoids. Movement sense is deduced as a sinistral strike-slip movement with evidence of rotation of sheared porphyroclasts, rotation of fragments and S/C-bands. The mylonite zone has been reactivated as fault which reveals oblique-slip movement. The fault resurges as faults which reveals normal(to the NW) and reverse(to the SE) dip-slip movement. Normal faults are dominant in the northern and southern part and reverse or thrust faults are dominant in the central part of the Okdong Fault. The thrust movement can be correlated with the Daebo Orogeny of Jurassic Period. Granites and dyke rocks intruded into Paleozoic and Precambrian rocks during Cretaceous Period.

Purpose - The Visegrád Group cooperation of the past 14 years and that of V4 for the past 20 years has very important significance in the 21st century that must be maintained. This cooperation is valuable because of the trade routes that connect northern Poland to the Balkans in southern Croatia, which forman important basis for the resuscitation of Central European development. Currently, because of the European manufacturing base and industrial development, an energy supply and stable energy distribution networks have been introduced to secure cooperation and not competition within the Visegrád Group. This paper's research emphasizes the supply chain hub in neighboring countries. Although Central and Eastern European countries are small, they can provide a competitive response to Western Europe if they collaborate with the V4 group and other countries. Research design, data, and methodology - The subjects of this study in the Visegrád Group area are related to the development of Marketing and Distribution Sciences in the integrated European Union. In relation to the existing energy infrastructure, construction companies and financial institutions benefit from large-scale construction projects. Existing or new infrastructure facilities among the V4 must comply with the preconditions of regional energy markets. The network of emerging markets is changing into a European-logistics hub of new markets. This hub is closely associated with the economic development of European self-sustainment given that energy for distribution and consumption is imported from Russia. Therefore, this paper indirectly provides data on the regional distribution of energy as alternative bases in Europe for market expansion to Asia. Results - As a result, it appeared unlikely that V4 failed to implement homogeneity following the standards of Western Europe, as proposed by the EU. Throughout European history, individuals have gathered in Central Europe as an innovation hub. Currently, the region is being established independently for energy industrial development and not for tourism development, and is expected to play a central role in innovation and distribution consumption. Therefore, similar to Western and Northern Europe, V4 only appears to engage in distribution consumption on the basis of the identity that it formed for itself. This area is expected to either create a regional platform or a voice over a single economic policy. Conclusions - To this end, regarding the distribution of consumer groups within and outside the region, the V4 group is expected to be established for various policy areas and as a Eurasian outpost of trade and distribution logistics. In addition, given its purpose of engaging in the distribution of energy cooperation and trade clusters, the Visegrád Group will be in charge of the center axis of the bridge for distribution logistics trading partners from the Western Balkans to Caucasus and Eastern Europe. Thus, the Visegrád Group is entering this region as a platform for market share by enabling all or any investor can gain greater industrial benefits.

Nutritional status of macro minerals (Ca, Mg and P) in goats grazed on the native pasture was investigated for 2 years in Luzon Island, Republic of the Philippines. Three regions in Luzon Island (Los Banos; Southern area, Munoz, Nueva Ecija; Central area and Baguio; Northern area) were objected to collect the samples of forages and blood of goats on the pasture. The average values in Ca, Mg and P contents of all the forage samples were 0.29-1.32, 0.13-0.56 and 0.15-0.45% of dry matter, respectively, and these figures almost exceeded the required dietary levels for sheep. There was no obvious changes in mineral content of forages between the seasons of rainy and dry, or among regions. In blood Ca level, more than a half of goats (57.9%) without supplement showed the level below the lower limit, and the low level was not improved even when they fed with some supplemental concentrates. The plasma levels of Mg and P were satisfactory, referring to the lower limit of normal level in goats. It is, therefore, necessary to decide the requirement and to establish a most suitable technique for supplying Ca to grazing goats in Luzon Island.

A collective theory is tried in analysis on the architectural history of Temple Gowoon in Gyongbook Province. For this purpose, firstly, the chronicle of construction was composed based on the critical study of the old documents. Secondly, the drawings of existing facilities were made after the field survey. And lastly, the collective theory was be able to extracted from the relation between chronicle and physical composion of the Temple Gowoon. The whole temple is composed of two territories, northern one and southern, which are divided by the central ravine. Northern territory was enlarged from Gukrakgeon's cluster through Myongboogeon's to Yeonsoogeon's. On the other hand, southern territory was reduced its position and its size from Daewoongeon's cluster, which was one of the main cluster, to Monigeon's, sub one. These processes were the results of the architectural adjustment, that is say, the dogmatic principles adapted in the topographical environments. The collective forms of clusters are different from each other. Gukrakgeon's cluster is composed of four buildings which enclose the empty inner court. Monigeon's is similar to the small temple type, Myongboogeon's selects the straggling form, and Yoensoogeon's has the type of Confucian shrine. The various types of clusters were the physical settings to symbolize the religious heirarchy of their buildigs. In the front of temple area, Gawoonloo, which located on the ravine and has a big volume, integrates straggling clusters.

The Yangsan Fault is one of the main fault systems in the Korean peninsula. It can be divided into three segments (northern, central, and southern) by its paleoseismic and structural geologic properties. Based on the geomorphic features of the northern segment, which includes the Yugye Fault, we identified deflected streams as a geomorphic marker of strike-slip component of the fault, and knickpoints along the streams as evidence of dip-slip component of the fault. Geomorphic analyses showed that (1) the horizontal displacements of deflected streams decreased and (2) the retreat amounts of knickpoints tend to increased toward north along the lineament. We interpreted the variations caused by strain partitioning; that is, there might be some increases of the vertical component toward north, whereas the main strike-slip fault system dies out, splaying into horsetail structure toward north. Based on the response time of the landforms, these interpretations imply that (1) there were differences between horizontal slip rate and vertical slip rate along strike, and/or (2) there were different timings between horizontal and vertical deformations by fault.
