The Belt and Road Initiative (BRI) is designed to intensify bilateral trade between China and the BRI countries through the improvement of transportation connections. However, little research has empirically investigated the impacts of this policies on the trade patterns. This paper attempts to evaluate the impacts of BRI on the trade patterns of Tanzania. Our study extends the original gravity model of bilateral trade by adding GDP per capita, population and proximity as the explanatory variables. According to our research, we observed that the BRI significantly impacted the Tanzania's trade patterns, as it led to the increase of bilateral trade flow between Tanzania and China more importantly between Tanzania and its adjacent countries. It indicates that the Belt and Road Initiative (BRI) has boosted Tanzania's trade exclusively, hence the Tanzania's export sector earns greater trading potential with the adjacent countries.

This study was performed in order to examine the effects of one to one interactive picture book reading on infants' reading response and teachers' language teaching efficacy. A total of 50 2-year-olds from 8 child care centers in Incheon were divided into an experimental group and a control group. The interactive picture book reading activities were carried out once a week during 12 weeks. The infants in the experimental group read one-to-one with teachers, and their counterparts read the same book in a group. The change in teachers' language teaching efficacy was examined, and their subjective perception was evaluated through in-depth interview. As a result of this research, the infants in the experimental group showed significantly increased verbal response, compared to the control group, both in the total score and most sub-factors such as naming, responding, asking, demanding, spontaneous utterance, and decontextualized utterance. They also represented a significant rise, compared to the control group, in the total score of non-verbal response and factors like finger indicating, imitating, and accepting. Finally, the teachers who led the experimental group showed increased language teaching efficacy, and evaluated the effects of interactive picture book reading with infants very positively.

Wireless LANs in the 2.4 ㎓ ISM- band create a new Electromagnetic Compatibility (EMC) problem. We investigated the interference characteristics between such wireless LANs in the case of identical systems, systems with different technical parameters for modulation and demodulation, and using a Gaussian noise source as a disturbance source. Experimental results show that higher throughput is obtained when adjacent wireless LANs use different systems, and that interference characteristics can be evaluated experimentally using a Gaussian noise source. Calculated BER characteristics for the interference agree with experimental measurements, indicating that this calculation method can be used for the design of the wireless LAN network to avoid interference. It is possible to construct an efficient wireless LAN network by combining different wireless LAN systems.

Since China opened its door to the world in 1978, its economic development had been concentrated in the Eastern and Western area compared with the middle area. From 2000s, the Chinese government started to develop the middle area in terms of balanced development. With this goal, "Plan on Zhengzhou Airport Economy Zone", and "One Belt and One Road" has implemented in Zhengzhou, where is the an important traffic center in middle area. Meanwhile, the foreign trade of Zhengzhou has been increased about 10 times between 2009 and 2018. In particular, its growth is the fastest among six central cities in 2018 from the lowest in 2009. This study investigates whether the Chinese government policy has an effect on the foreign trade of Zhengzhou. We find that based on the regression analysis of the Principal Component Analysis (PCA), the government policies has a positive impact on the development of Zhengzhou's foreign trade. It is meaningful that the government policy focused on the advantage of Zhengzhou contributes its development of foreign trade.

The purpose of this study is to examine the main features of South Korea's New Northern Policy and to make some suggestions for cooperation with neighboring countries' initiatives. The New Northern Policy encompasses the whole of Eurasia, but the starting development area would be the border region of the Korean Peninsula. In this viewpoint, this study examines the Belt and Road Initiative of China, the New Eastern Policy of Russia and the Steppe Road Initiative of Mongolia, and presents the characteristics, problems and some implementation strategies of the New Northern Policy. Apart from the future possibilities of the regional cooperations that include North Korea, it would be necessary for South Korea to secure and expand the possible opportunities for "Korea-China-Mongolia-Russia" cooperation. In order to create a close cooperative environment with North Korea in the future, it would also be necessary to build a maritime route, with port development around major border regions on the Korean Peninsula, including Russia, and to develop the port-railway intermodal transportation system with neighboring countries. South Korea need to actively cooperate with neighboring countries to develop the new Eurasia logistics routes would be more favorable to the Korean Peninsula in preparation for the time when the North Korean nuclear issue will be resolved.

편집자주:대한민국 국회의사당의 신축설계를 둘러싸고 그동안 많은 물의와 논란을 야키케 하였다. 이러한 현상은 우리나라 건축계의 현실을 여실히 나타낸 것이라 보겠으며 그 진행되었던 설계과정이 어떠했던간에 지난 2월5일부터 2월8일까지 신문회관에서 일반에게 공개되었떤 이후로는 일단 문제는 우리의 권외에서 매듭이 지어졌다 하겠다. 국회의사당 신축설계야 말로 그 의의로 보나 우리 한민족의 일대 커다란 사업이니 만큼 그동안 설계를 위해서 노력을 아끼지 않으신 안영배 회원께서 그 동안의 많은 애로와 또 건축사들이 한국적인 현실에 직면하지 않으면 안되었던 상황을 오늘 본회지를 빌어서 발표하게 되었다.

This paper proposes a Near Field Communication (NFC) communication system that exchanges information of digital business cards efficiently for many to many communication to solve inconvenience of one-to-one communication when people exchanges business cards each other in meetings such as conference, forum, seminar. The proposed system can provide people to exchange contact information one-to-one as well as multiple members at once using a digital business card system that consists a server and a database based on NFC communication. The system has been developed to collect business card information from a NFC reader and to transfer it directly to a smartphone application effectively. The system can manage business card information with the application effectively and provide security in order to prevent from leakage of private information when transferring contact data.

전라남도 진도군 조도면에 위치한 섬 가사도. 이 섬마을 방문하려면 하루에 왕복 1차례 밖에 없는 배편을 이용해야 한다. 특별한 일이 아니고서야 방문할 마음조차 쉽사리 먹기 힘든 그러한 전형적인 섬마을이다. 이러한 섬마을에 일대 대변혁의 바람이 불기 시작했다. 지난 2012년 이후 정부와 한국전력공사가 추진하고 있는 마이크로그리드(MG)를 이용한 에너지 자립섬 시범단지로 자리매김했기 때문이다.
