급속도로 발전하고 있는 동북 아시아, 그 중 중국에서 배출되는 대기오염물질의 장거리 이동은 여러 나라에 영향을 주고 있으며, 이는 관련 국가의 큰 관심의 대상이 되고 있다. 장거리 이동은 국제적인 문제로 이출 해결하기 위해서는 과학적인 접근과 정책적인 접근이 동시에 이루어져야 한다. 기존의 연구들에서는 한가지에 초점을 맞춘 접근을 주로 하고 있으므로(김용표, 1999), 본 연구에서는 두 가지 접근을 모두 시도해보고자 한다. Regional Air pollution INformation and Simulation - Asia(RAINS- Asia)Modeling을 통해 중국, 한국, 일본 세 국가의 이산화황 배출에 따른 침적량을 분석해 보았고, 향후 30여년 간의 추세를 예측해 보았다. (중략)

올 1월 말 바르셀로나에서 열린 3GPP Next Generation Access Requirement AH는, 10여 년전 4G LTE가 처음 논의될 때와 비교하면 열기가 뜨겁다는 것은 여전하지만, 주역들은 많이 바뀌었음을 느낄 수 있었다. 4G 논의 때에는 유럽, 일본이 주도하고 북미, 한국은 따라가는 상황이었다면, 5G 논의는 중국이 전면에 나서고 한국, 유럽이 따라가는 패턴을 보여주고 있다. 엄청난 규모의 중국 내 TD-LTE 시장을 무기로 차세대 기술과 표준논의를 주도하고 있는 중국 사업자와 제조업체의 위상을 실감할 수 있는 자리로 보인다. 우리 나라는 LTE 기술 개발과 상용화 시점, 보급율 현황 등에서 타국의 추종을 불허하는 스피드를 보여주었고, 덕분에 우리 국민들은 세계에서 가장 앞선 모바일 서비스를 누리고 있고, 그 여세를 몰아서 5G 논의의 물꼬를 튼 것도 사실이다. 그러나 시장에서는 시작은 반이 아니고 시작일 뿐이다. 본 무대를 어떻게 연출해 가느냐에 따라 주도권을 계속 가져갈 수도, 한순간에 밀려날 수도 있는 것이 냉엄한 현실이다. 금년부터는 5G에 대한 기술 표준화가 본격화 되는데, 이와 병행해서 기술 개발, Joint Trial, 시험 주파수 할당, C-P-N-D-M 생태계 확보 등의 작업이 정신없이 진행될 것으로 예상된다. 한정된 국가적 자원을 효율적이고 효과적으로 활용하기 위한 산학연관의 지혜가 더욱 필요한 시기가 오고 있으며, 이번 5G특집이 그 고민의 계기가 되면 좋겠다.

The purpose of this study is to identify the characteristics of China's trade relationships with and dependency on the countries participating in the Belt and Road initiative and to present some implications. This study collected annual total imports, exports, and GDP data from the International Monetary Fund (IMF) on 198 countries and the National Bureau of Statistics of China (NBS) on 221 countries from 1995 to 2015. China's imports and exports have expanded considerably from the mid-1990s to the present, and China's dependence on imports and exports with the US and Japan has declined, while its dependence on the Middle East, South Africa, South America, and Southeast Asia has increased. China has a very high level of dependence on imports from and exports to the countries participating in the Belt and Road initiative, and as the Belt and Road project progresses, the mutual trade dependency between China and the other participating countries is expected to strengthen and expand.

A variety of PPP (Public-Private Partnerships) schemes including BOT, TOT (Transfer-Operate-Transfer), and divestiture has been employed in the Chinese water sector. Although the two latter emerging models have been implemented in their full applications lately, there has been no follow-up for identification of opportunities and challenges inherent in those schemes in relation to the market participation of foreign investor. This study undertakes in-depth analysis on the TOT and divestiture projects in the SWOT (Strengths, Weaknesses, Opportunities, and Threats) matrix and measures the level of agreement on each SWOT through a survey among the Chinese water market experts. The findings can be used to support foreign investors in managing the weaknesses and threats that, unless properly managed, can be evolved into potential project risks, while fully benefiting from the strengths and opportunities of the two schemes.

This study focused on relationships among leisure involvement, experience quality and behavioral intention in the urban parks. A total of 335 were collected, and during the data refinement process, 39 questionnaires were eliminated from the study due to partial and inconsistent responses. thus leading to 296 usable questionnaires out of 335. In the final result, 296 questionnaires were coded for the analysis purpose. The hypothesized conceptual model was used to analyze the Descriptive Analysis and Frequency Analysis, Exploratory Factor Analysis, and Multiple Regression Analysis using SPSS 24.0. The result indicated this: residents' experience quality in urban parks depends on more attraction and centrality of leisure involvement than on the self-experience quality of leisure involvement. The results of this study also indicate that not all experience dimensions are important for resulting in positive behavioral intentions to urban parks. The quality of education, esthetic, and escape experience showed a significant predictor of behavioral intentions, while the quality of entertainment experience did not show a significant positive relationship with behavioral intentions.

While many countries are implementing various policies regarding the logistics network in Eurasia, China has presented "the Belt and Road" Initiative, a development strategy that focuses on connectivity and close cooperation between China and Eurasia. With more than 60 countries participating in the project, China is expected to have a major influence on logistical infrastructure development in Eurasia. This study analyzed the railway stations network using social network analysis (SNA) methodology. We collected data from major railway lines in Eurasia (TAR, TEN-T, TRACECA, GMS) and established a network of 994 railway stations in 65 countries. This study presented the general characteristics of major railway stations from the perspective of SNA and compared the Chinese network with Eurasian networks. To review the railway networks in China and Eurasia, the top 30 stations were selected based on degree centrality and betweenness centrality. Top "degree centrality" stations included Bangkok (Thailand), Tbilisi (Georgia), Baku (Azerbaijan), Kunming (China), and Bucharest (Romania). Top "betweenness centrality" stations were Baku and Alyat (Azerbaijan), Baoji and Turpan (China), Qarshi (Uzbekistan), and Kas (Turkey). In China, Kunming, Nanning, and Gejiu stations have higher degree centrality while betweenness centrality was higher in Baoji, Kunming, and Lanzhou stations. "The Belt and Road" project advocated by China envisions expansion of transportation infrastructure connections throughout Eurasia, but more emphasis is likely to be placed on connectivity that benefits China. In this regard, studies on key bases of international logistics need to consider relative significance within the Chinese network.

전보에서 외국산에 의해 기록된 한반도산 날개응애류 26종과 필자가 채집한 미기록종 29종 도합 65종의 목록을 발표한 바 있다. 그 후의 채집품을 조사결과 다수의 미기록종이 발견되었기에 전보를 증보하여 발표한다. 이로서 한반도산 날개응애류는 29상과, 59과, 99속, 158종이 되었다. 이밖에 미정리분중에도 약 50중의 미기록종이 포함되어 있으므로 한국산 날개응애류는 200여종이 되는 셈이지만 한국에 실재하고 있는 종수는 그 $2\~3$배가 될 것으로 추측된다. 또한 분포를 논할 단계는 아니지만 일본과의 공통종은 69종, 구주와의 공통종은 51종, 3자공통종은 55종이 되어 한반도 고유종은 34종이 된다. 그러나 우리나라와 인접해 있는 중국대륙의 날개응애상이 밝혀지면 고유종은 줄어들고 중국과의 공통종이 많아질 것이다.

이미 작고한 중국의 자도자 등소평이 복용하여 장소를 누렸다고 하는 동충하초. 1992년 일본 히로시마에서 개최된 국제육상경기대회에서 마준렌이 이끄는 중국의 육상선수들이 신기록을 양산한 비결로 알려지면서 더욱 유명해진 버섯이다(1). 그런데 최근 국내에서 동충하초가 건강식품으로 인지도가 높아지면서 이의 판매를 둘러싸고 이해가 대립된 기관 또는 농민 집단 사이에 마찰이 발생하고, 일반 소비자는 동충하초에 관한 정확한 지식이나 정보가 없는 가운데 상인들의 상술에 농락당할 우려가 있어 자칫 건강에 유익한 새로운 식품소재에 대한 불신이 높아질 수 있는 문제가 발생하고 있다. 따라서 저자는 동충하초에 대한 모든 사람들의 이해를돕고자 그 동안 진행되어 온 상황을 설명하고 (1999년 9월까지), 여기에 내포된 문제점을 지적하였으며, 끝으로 동충하초를 국내 산업에 국한할 문제가 아니라 전세계적으로 동충하초 시장을 석권할 수 있는 발전방향과 규제완화 필요성을 제기하였다. 동충하초에 관한 일반 사항과 효능에 관하여는 저자들이 식품과학과 산업에 투고한 총설에 관련 문헌을 종합하여 요약한 바있다.

In this study, we conducted an analysis on the actual field materials and the ancient text of January 2017. First, Yuyin ShanFang is one of the famous garden in the Lingnan Region, and its total area is $1598m^2$. Wobin called the name 'Yuyin(餘蔭)' meaning the virtues of his ancestors. Second, if we analyze the poem written by Wobin, we can classify it as a phrase expressing the world beyond the future, a poem expressing the ideas of family and romantic ideas. Third, the space spread to the south around the shrine building in the middle of the site was largely a residential space, according to the analysis of the site's layout and spatial composition. Fourth, the spatial component of the hydronic acid is analyzed. The pavilion area is the Hanchwi-Pavilion, which is designated in the Wongrim, and Gyesang-Pavilion, which is a unique range that describes the peak of the garden. Fifth, Yuyin ShanFang has five ponds that are very diverse in shape. It is characteristic of us to stand on a technical boundary. Sixth, Seokgasan was referred to as Gyeongbansan, which was named after The builder Wobin and his descendants who passed it. Seventh, Hwachang is characterized by a wooden bull window and a compound glass. Eighth, the alumni style is not as diverse as the alumni style of the Suzhou traditional garden, but it features various forms and colorful pictures on the front of the alumni. Ninth, the one-piece sculptures of the interior of a building are expressed themes such as Gilsang, Sukjeong, Daoism, Palseom, and others. Finally, Trees planted in Yuyin ShanFang are mostly tropical plants, and some of them have symbolic meaning. Because the weather here is good for growing fruit, so planted a lot of fruit trees.
