This study was conducted to improve the continuous techniques for international competitiveness of ginseng industry to Korea-China FTA negotiation and conclusion, and provide the basic information for ginseng industry development of Korea. It was carried out the visiting of the northeastern three provinces (Jilin, Liaoling and Heilongjang) in China for 3-year from 2014 to 2016 and observed the farmers' fields of ginseng cultivation with soil environmental status. The types of ginseng cultivation could be observed in small scales of 0.5~3.0 ha, in middle scales of 4.0~10.0 ha and in large scales of 30~700 ha with the kinds of imhasam, Chinese ginseng, Korean ginseng and western ginseng. Also ginseng was cultivated in newly reclaimed land of forest in two types of direct seeding and transplanting of ginseng seedlings. The field beds of ginseng growing were covered with vinyl films in arch design of 100~130 cm height and vinyl was painted in spraying with blue, green and yellow colours for shading. It was investigated in status of the physico-chemical properties of soils. The physical information on the field soils were silt loam, loam and sandy loam in soil textures, and some plain in low slope, some alluvial fan or local valley in forest of land topography. Soil pH ranged within 5.0~5.2, soil EC was $0.93{\sim}3.78dS\;m^{-1}$, organic matter was $37{\sim}35g\;kg^{-1}$, nitrate nitrogen $63{\sim}490mg\;kg^{-1}$, available $P_2O_5$ $55{\sim}163mg\;kg^{-1}$, and in exchangeable cations, K was 0.30~0.98, Ca was 6.5~14.0, Mg was $1.1{\sim}5.3cmol_c\;kg^{-1}$ in ranges. Farmers used the fertilizer for ginseng cultivation in 10~11 t of compost, $200{\sim}400kg\;ha^{-1}$ of complex fertilizer and $750kg\;ha^{-1}$ of oil cakes. The northeastern three provinces of China can use the newly lands with large areas of ginseng cultivation in soil sickness by continuous cropping. and the soil basic fertility is batter than that of Korean in standard guide of ginseng cultivation soil.

A satellite tracked drifter experiment was conducted to observe thermal structure and surface circulation in the northeastern East China Sea. For this experiment, four ADOS buoys, assembled with surface float and thermister chain, were deployed on August 2007 in southern Jeju-do, where the Kuroshio Branch Current is separated from the main stream. Thermal structure in the upper layer of the northeastern East China Sea was successfully observed during the following $1{\sim}3$ months. Strong thermo-haline front in a northeast-southwest direction was observed. In the frontal zone, warm and saline Kuroshio origin water intermixes with fresher coastal water and flows toward the Korean Strait. Typhoon Nari, which passed over the East China Sea 20 days after commencement of study, caused distinct signals in the thermal structure and trajectory of buoys. During the typhoon, surface temperature abruptly dropped to about $4^{\circ}C$, while the thermocline formed at $30{\sim}50$ m depth vanished due to strong vertical mixing. Internal inertial oscillation occurred several days after the typhoon. The fortuitous occurrence of typhoon Nari showed that ADOS buoys can provide useful and accurate air-sea interaction data during typhoons.

The rapid industrializing of China has helped the development of the industrial economy since 1980. However, the problem is some environmental pollution, such as SO$_2$, TSP, HOx, Dioxin etc, generated by the industrial facilities located in Northeastern China is moving to the Korean Peninsula through the cold air stream during the Asian dust season, This kind of air pollution worsens the environmental pollution of the Korean Peninsula year by year. Therefore, NGO suggests to China that the minimization of the environmental problems linked to both Korea and China has to be discussed. In fact, I would like to suggest that the activity of EMS(ISO14000) should help the environmentally sound '||'&'||' sustainnable development of both countries,

In this parer, by means of adding nonsuperconductive phase sliver into YBCO matrix, the superconductivity of Melted Texture Growth (MTG) YBa$_2$Cu$_3$O$\_$7-x/ was improved remarkably. In order to eliminate the crack inthe YBCO and the weak linkin the grain boundary, Ag contents from 2wt% to 18Wt% were doped in the YBCO It was found that J$\_$c/ of YBCO increase with the increasing Ag content till 14 wt% over 14wt% of Ag content, the Jc tends to stable . The grain size of YBCO became fine when Ag was added in the YBCO and X-ray diffraction showed that the YBCO crystal prepared by the above technique had (001) orientation and growing plane of YBCO was a-b plane. Using Bens medel, the J$\_$c/ was calculated and the best result was J$\_$c/ 76000A$\textrm{cm}^2$(77K, 100Gs).

The purpose of this study is to analyse the characteristics of style, color and items of street fashion in Harbin. This kind of study will contribute to the understanding the preference of fashion in northeastern area, thereby, affording a fundamental resources for the strategic establishments of design and marketing in Korean brand launching into China. The results of this study are as follows. The preferred fashion style is casual one, rather than formal one. The order of preference in casual wear is character, jean and sports casual. In the view of color, preference in top color is, white, black, brown and pink. In the bottom, it is blue, white, black and brown. In one-piece, it is white, blue and brown. Throughout all items, the most frequently founded color is white, which might be ascribed to the seasonal influence of summer. The Chinese specific preference of color could not be observed. In aspect of items, the one-piece takes the proportions of more than half of the all the items. The typical details of one-piece dress are irregular hemline and asymmetrical line. While knee length takes proportion of 70%, in item of skirt, the full length is 46.8% in frequency for pants. In one-piece, knee length is 80% amounted as first rank, followed by midi and mini.

Three species of the genus Sciota Hulst, 1888 are recognized from Northeast China: Sciota cynicella (Christoph, 1881), Sciota fumella (Eversmann, 1844), and Sciota adelphella (Fischer von R$\ddot{o} $slerstamm, 1836), of which Sciota cynicella (Christoph, 1881) is reported for the first time from China. This species can be distinguished from congeners by the gray color of basal area, the straight antemedial line and the distinct postmedial line on the forewing; by the stout aedeagus in male genitalia. In this study, a key to Northeastern Chinese species of genus Sciota is presented, and the illustrations of adults and genitalia are also provided.

중국은 1970년대 후반 개방개혁정책과 더불어 급속한 경제성장을 이루어왔다. 중국 경제성장은 초기에 동남부 연해지역을 중심으로 시작되어 2000년대부터는 상대적으로 경제가 낙후된 서부 및 동북부 지역으로 확산되었다. 특히 2013년 시진핑의 '일대일로' 이니셔티브는 중국의 대외진출 전략인 동시에 이들 지역발전을 위한 중요한 계기를 마련해주고 있다. 내륙항은 내륙지역의 물류중심지로서 해양항만과 연계 및 주변 내륙국가로의 접근성을 강화시키는 데 결정적인 역할을 한다. 따라서 중국의 동북부 및 서부지역의 해외시장 진출 및 자원확보를 위해 다수의 내륙항이 개발 및 운영되고 있다. 본 연구는 일대일로 이니셔티브에서 내륙항의 역할과 발전을 전망해 보는 데 목적이 있다. 결론적으로 일대일로 이니셔티브에서 내륙항의 역할은 더욱 증대될 것이며 이에 대응하여 내륙항의 발전 역시 일대일로 이니셔티브에서 중추적 역할을 하게 될 것이다. 따라서 우리나라 기업은 중국 내륙항의 개발 및 운영에 참여할 수 있는 방안의 수립을 적극적으로 고려해야 할 것이며, 이는 중국, 러시아, 중앙아시아, 동유럽 지역으로 시장을 확대해 나가는 데 좋은 기회를 제공할 것이다.
