Domestic IOP (intensive observing period) has mostly been represented by the KEOP (Korea Enhanced Observing Period), which started the 5-yr second phase in 2006 after the first phase (2001-2005). During the first phase, the KEOP had focused on special observations (e.g., frontal systems, typhoons, etc.) around the Haenam supersite, while extended observations have been attempted from the second phase, e.g., mountain and downstream meteorology in 2006 and heavy rainfall in the mid-central region and marine meteorology in 2007. So far the KEOP has collected some useful data for severe weather systems in Korea, which are very important in understanding the development mechanisms of disastrous weather systems moving into or developing in Korea. In the future, intensive observations should be made for all characteristic weather systems in Korea including the easterly in the central-eastern coastal areas, the orographically-developed systems around mountains, the heavy snowfall in the western coastal areas, the upstream/downstream effect around major mountain ranges, and the heavy rainfall in the mid-central region. Enhancing observations over the seas around the Korean Peninsula is utmost important to improve forecast accuracy on the weather systems moving into Korea through the seas. Observations of sand dust storm in the domestic and the source regions are also essential. Such various IOPs should serve as important components of international field campaign such as THORPEX (THe Observing system Research and Predictability EXperiment) through active international collaborations.

본 연구의 목적은 마오쩌둥 이후 중국 지역 발전 정책의 진화와 공간 불균등과의 관계를 분석하고자 하는 것이다. 이를 위해 본 논문은 1인당 GRDP 변동계수와 지니계수를 적용하여 중국 31개 시·성·자치구 간 지역 경제력 격차와 지역 발전 정책과의 관계를 분석하였다. 중국의 지역 간 경제력 격차는 1979년 이후 심화되었다가 제10차 5개년 계획(2001~2005년) 이후 중부, 서부, 동북부 지역의 지속적인 정부 주도의 대규모 경제성장 정책에 따라 완화되는 것으로 분석되었다. 그러나 이는 31개 시·성·자치구 전체를 대상으로 분석한 결과이며, 동부, 중부, 서부, 동북부 4대 지역을 대상으로 GDP 변동계수를 각각 분석했을 때 상이한 결과가 나타났다. 예를 들어, 제10차 5개년 계획 이후 중부 지역 내 격차는 지속적으로 심화되었지만 서부와 동북부의 지역 내 경제력 격차는 지속적으로 완화되었다. 이는 중국의 지역 간 경제력 격차를 완화시키는데 큰 역할을 한 것으로 분석되었다. 특히 동부 지역 내 격차는 제12차 5개년 규획(2010~2015년) 이후에도 지속적으로 심화되어 중국 지역 경제력의 수렴 현상이 둔화되는 결과를 가져왔다. 이는 제11차 5개년 규획(2006~2010년) 시기에 본격적으로 시행되었던 중부 권역 발전 정책의 한계에 기인한 것으로 볼 수 있다.

In this paper we have introduced some results of study on stand growth pattern and stand structure of larch forest which are located in selected forest sites of Khangai and Gobi-Altai mountain ranges of Mongolia. Our investigations showed that growth intensity and stand structure in western Mongolia are very specific from the other forest vegetation zones of Mongolia. Studies on the stand structure and growth trend indicate that tree types of stand structure and different types of growth of Larix sibrica are very common in Western Mongolia. These peculiarities of stand structure and growth of larch stands in Western Monolia could be used for inventory work and an improvement of the forest management in Western Mongolian region. The larch tree is the dominant tree species in Western Mogolia. Forest cover of the region is about 15%, which is two times higher than the country's average. In this region forest area is divided into 4 forest sub-regions: the Central Khangai, Western Khangai, North Eastern Khangai and South Easterun Khangai sub-regions including taiga, pseudo taiga, sub taiga, sub-alpine and forest steppe belts. Silviculture practices and forest research management request to study forest growth trends in local and general conditions, which means to indicate a change of taxonomic characteristics of stand from time to time including diameter, height, basal area, growth stock etc. The forest management practice mostly uses tables of forest growth and yield based on the results of long term research on forest growth. Forest yield tables and other relevant forest standards of Russia are used for the forest inventory and forest management. They are not able to determine forest structure and growth peculiatities of Mongolian forests. Studies on forest resource assessment in Mongolia indicate that after logging operations and forest fires the natural regeneration of desired species such as pine and larch often does not succeed. This situation forces to take a different approach of forest management and silviculture practice depending on the stand structure and growth rate of the forest stands. According to our investigation in last years, forest growth pattern of larch forest depends mostly on stand structure, stand age and growth condition including forest soil, climate and location in different slopes. Due to improve environmental function of forest ecosystem in the region, it is needed to conduct very comprehensive study of high mountain forest ecosystem in selected sub-regions.

Matting made of wools has a history which gose back even before B.C.7000, the time which is believed to be the starting point of the fabrication, production and usage of wools by the nomads in the Western and Central Asia who had made the living by breeding sheeps. The purpose of this thesis is to investigate the function of wool matting in Asia. The research period limited to 9C A.D. When classified by the method of production of wool matting, the pile method and felt method have been widely used by the nomads in Western Asia and the cattle breeding nomads in Central Asia consecutively. From ancient times, wool matting has been considered to be one of the necessities by the nomads for living in the wilderness, and even at present, continued to be used by the people both for the purpose of everyday use and decoration. Other than fore-mentioned purposes, wool matting have function that is expressed the incantation, authorization and hierarchy, emotion and desire, and cultural exchange between nations. In addition, wool matting had also been used as a mark to show ownership and for military purposes. Even a simple wool matting had a different symbolism and function by different region and people throughout Asia. However, by finding and studying further abut what wool matting had symbolized and how it had been used, the tradition and history of wool matting could continue to attract the interests which will make the tradition to continue. And also, in order for the tradition to continue, the utmost efforts to innovate and produce better quality and design wool matting to fulfil the needs of modern times are truly required.

This study investigates the characteristics of the Gross Moist Stability (GMS) over the tropics. The GMS summarizes the relationship between large-scale entropy forcing due to radiation and surface fluxes and the response of smaller-scale convection. The GMS is able to explain both to where moist entropy is advected by the atmospheric circulation and how deep the moisture flux convergence is in the tropical region. In the deep convective region, positive GMS appears over the warm pool region due to the strong column-integrated moisture convergence and the ensuing export of moist entropy to the environment. The vertical advection of moist entropy dominates over the horizontal advection in this region. Meanwhile, over the eastern tropical ITCZ region, which is characterized by shallow convective area, import of moist entropy by horizontal winds is dominant compared to the vertical moist entropy advection. Future changes in the GMS are also examined using the 22 CMIP5 model simulations. A decrease in the GMS appears widely across the tropics, but its increase occurs over the western-central equatorial Pacific. It is evident that the increased GMS region corresponds to an increased region of precipitation, implying that strengthened convection in the future due to increased entropy forcing exports the enhanced moist energy to stabilize the environment.

실체현미경과 전계방출형 주사전자현미경 관찰, 에너지분산형 분광분석기를 이용한 화학 분석을 통하여 황해중앙이질대에서 채취된 46개의 표층 퇴적물 시료 내에 포함되어 있는 중광물의 종류, 함량, 광물 특성 및 분포를 연구하였으며, 이 결과를 바탕으로 조립질 퇴적물의 기원지를 유추하였다. 황해중앙이질대 표층 퇴적물 내에 존재하는 중광물들은 녹렴석군 광물, 각섬석군 광물, 석류석군 광물, 저어콘, 금홍석, 스핀 순으로 산출하는데, 특히 녹렴석군 광물과 각섬석군 광물의 비율이 50% 이상으로 매우 높다. 녹렴석군 광물은 녹렴석, 각섬석군 광물은 에데나이트, 석류석군 광물은 알만딘이 대부분인 것으로 판단된다. 황해중앙이질대를 $124^{\circ}E$ 기준으로 구분할 경우, 동부지역이 서부지역에 비해 녹렴석 및 풍화에 강한 (저어콘 + 금홍석)의 함량은 높고, 풍화에 약한 각섬석의 함량은 낮게 나타난다. 이는 서부지역의 퇴적물은 기원지에 가까운 곳에, 동부지역의 퇴적물은 기원지로부터 먼 곳에 퇴적되었을 것임을 시사해준다. 추후 황해로 유입되는 강 퇴적물과 해양 퇴적물에 대한 추가적인 중광물 연구가 진행되어야만 정확한 기원지와 퇴적과정에 대한 해석을 할 수 있을 것으로 여겨진다.

NCEP reanalysis data were analyzed in order to provide distribution of global wind resource and wind speed in the surface layer for the years 2000-2009. Wind speed at 10 m above ground level (AGL) was converted to wind speed at 80 m above the ground level using the power law. The global average 80 m wind speed shows a maximum value of $13ms^{-1}$ at the storm track region. High wind speed over the land exists in Tibet, Mongolia, Central North America, South Africa, Australia, and Argentina. Wind speed over the ocean increased with a large value in the South China Sea, Southeast Asia, East Sea of the Korea. Sea surface wind in Western Europe and Scandinavia are suitable for wind farm with a value of $7-8ms^{-1}$. Areas with great potential for wind farm are also found in Eastern and Western coastal region of North America. Sea surface wind in Southern Hemisphere shows larger values in the high latitude of South America, South Africa and Australia. The distribution of low-resolution reanalysis data represents general potential areas for wind power and can be used to provide information for high-resolution wind resource mapping.

The present study was undertaken in middle altitudinal (1500 to 2500 masl) moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim of the present study was to assess the variation in species composition and diversity in different vegetation layers viz. herb, shrub and tree, at different altitudes. Shannon-Wiener diversity index ($\bar{H}$), $Nha^{-1}$, total basal cover per hectare (G), Simpson concentration of dominance, Pielou Equitability, species richness (SR), Margalef index, Menheink index of species richness and ${\beta}$-diversity were calculated to understand community composition. Tree G ranged from 84.25 to 35.08 $m^2ha^{-1}$ and total stem density varied from 990 to 1470 Nha-1. Total SR (herb, shrub and trees) among different forest types ranged between 31 and 58. Maximum G of herb and shrub layers was recorded at lower altitudes between 1500 and 1650 masl. ${\beta}$-diversity was higher in herb layers as compared to tree and shrub layers. Dominance-diversity curves were also drawn to ascertain resource apportionment among various species in different forest types. Values of species diversity, $\bar{H}$, $Nha^{-1}$ and G were higher in the study area as compared to similar forests growing in other parts of Uttarakhand Himalaya.

This study examined the essential elements of urban fishing ports in the region of Busan in terms of the hydrography, geomorphology, and urban functions of each fishing port and then estimated their development potential. The results were as follows: (1) The ports in the eastern and central parts of the Busan region, used mostly for fishing, were open or quasi-open type ports with ${\Omega}>0.8$, while those of the western part tended to show the reverse. (2) Of the 51 fishing ports, 37.3% were located on land inside the coastline, and structures such as breakwaters had been constructed on both sides of the entrance. Of the total, 47.1% were small fishing ports with water depths of 0~1 m. (3) In the Busan region, 39.2% were urban fishing ports, including Daebyeon and Dadaepo, and 60.8% were non-urban fishing ports.
