인천시의 자매도시간 교류의 일환으로 일본의 기타규슈와 후쿠오카, 뱃부, 나카사키 일대를 지난 1월 19일부터 5일간의 여정으로 테마여행을 다녀왔다. 탐방단은 인천의 시민단체, 교사, 학생, 전문가, 대학교수, 공무원 등 120명으로 구성되었다. 이번 일본방문은 지방자치시대의 시민모임 활성화와 다양한 직업을 가진 각계 각층 사람들의 눈을 통해 자신과 인천 그리고 국가의 미래를 생각하게 하는 정보 및 인식공유의 계기가 되었다.

It is very important for libraries to provide their patrons with spaces that are used comfortably. In this paper, first we propose some improvement plans for space organizations of Gwacheon Public Library based on its patrons' behavioral research. It has a big meaning from the view of library marketing, which aims at improving patrons' satisfaction. Then we investigate how study tables are used based on the data taken at Kyushu University Library in Japan. Finally we put some proposals on libraries' space organization based on these investigations.

In this paper, the features and meanings of the Yocoanabo (cave tombs) excavated in the Gongju and Buyeo regions were examined. The creation of the Yocoanabo in the Korean Peninsula was related to the situation in which the powers of the Northern Kyushu (九州) and Yeongsangang (榮山江) River Basin played certain roles and maintained power in the interactions of Wa and Baekje in the late 5th century until the early 6th century. The people buried in the Yocoanabo in the Gongju and Buyeo regions are most closely related to the Buzen (豊前) area in northern Kyushu. They also interacted with the Yeongsangang River Basin communities. The Yocoanabo in Gongju and Buyeo confirms the settlement of the Wa people. There were collective settlements such as the Danjiri (丹芝里) site on the outskirts of Woongjin (熊津). However, most of them were mixed with small local groups located on the main roads connecting Woongjin and Sabi (泗?) through the Geum River and land routes. Unlike the keyhole-shaped tombs of the Youngsangang River Basin, the Yocoanabo was not built until the 7th century. This explains differences in the backgrounds of the two types of graves. The people buried in the Yocoanabo are considered to have settled in the Baekje Kingdom and to have been responsible for practical work in the political and economic negotiations between Baekje and Wa. They came to the Baekje Kingdom collectively in connection with certain historical events. However, it had been presumed that most of the people came individually and dispersed to the local communities of Gonju and Buyeo.

일본강점기에 수원고등농림학교를 졸업, 일본으로 건너가 조선인으로는 입학하기 어려웠던 규슈대학 농학부를 나온 후, 해방되던 해에 수원중앙농업시험장의 전작계장으로 부임한 인연을 시작으로 50년여 동안 우리나라 밭작물의 발전과 농학도 양성에 매달려 온 서하 조재영(西荷 趙載英) 박사(93)를 서울 서초구에 있는 한국학술원에서 만났다. 조박사는 1950년대에 보리, 밀 고구마 신품종을 개발, 농가에 보급해 '보릿고개'를 극복하게 했고 밭작물의 재배 및 육종 연구를 토대로 '재배학범' '전작'을 저술해 우리나라 작물학의 초석을 다져낸 이후, 오로지 그 일에 몰두하여 작물학 체계를 집대성해냈다. 황해도 연백 출생으로 대한민국 과학기술상 수상, 국민훈장 목련장 등을 수훈했다.

With the help of various Layer 2 triggers, Fast Handover for Mobile IPv6 (FMIPv6) considerably reduces the latency and the signaling messages incurred by the handover. Obviously, if not secured, the protocol is exposed to various security threats and attacks. In order to protect FMIPv6, several security protocols have been proposed. To our best knowledge, there is lack of analysis and comparison study on them though the security in FMIPv6 is recognized to be important. Motivated by this, we provide an overview of the security protocols for FMIPv6, followed by the comparison analysis on them. Also, the security threats and requirements are outlined before the protocols are explored. The comparison analysis result shows that the protocol presented by You, Sakurai and Hori is more secure than others while not resulting in high computation overhead. Finally, we introduce Proxy MIPv6 and its fast handover enhancements, then emphasizing the need for a proper security mechanism for them as a future work.

Saussurea taquetii reported from Jejudo Island is either treated as a synonym of S. japonica or is recognized as a distinct taxon. Saussurea japonica and S. pulchella belong to the sect. Theodorea by having peculiar outer phyllaries with pale purplish scarious apical appendages; they are closely related to each other morphologically and are known to occur widely throughout the Korean Peninsula. To assess the taxonomic status of S. taquetii, we investigated representative populations of S. taquetii from jejudo Island, Korea, and S. japonica from Kyushu in Japan. We conducted a comparative study morphologically using specimens of three species from KH, CNU, and TI. Saussurea taquetii is very similar morphologically and ecologically to S. japonica in Kyushu. Unlike previous floristic treatments, we concluded that the two taxa, S. pulchella and S. taquetii, occur on the Korean Peninsula and on jejudo Island, respectively.

본 논문에서는 먼저 영남지역의 장기적인 전력부족을 해결하기 위하여 일본의 규슈지역과 남한의 부산지역을 KVDC로 계통연계를 위한 시나리오 및 전력 조류의 분포도를 분석하는 것을 목적으로 한다. 특히 경인지역과 영남지역은 부하의 중심지라고 할 수 있으며, 영남지역은 현재의 경우에도 발전량보다 부하량이 많은 것으로 나타나 있다. 이러한 추세는 향후 계속적인 전력수요의 증가로 인해 더욱 문제가 될 것이며, 이런 증가하는 발전력의 부족을 해결할 만한 마땅한 대책이 없으리라 여겨진다. 본 논문의 시나리오에서는 영남지역에 전력을 공급할 목적으로 되어있기 때문에 일본측을 컨버터로 한국측을 인버터로 하여 일본에서 한반도 방향으로 전력을 흘려보내도록 하였다. 양국의 HVDC 전력 계통연계는 가상으로 시나리오를 작성한 후, PSS/E Tool을 사용하여 조류 계산을 시행하여 전력 분포도를 살펴보았다.

A Supersonic air intake model was designed for the high performance ramjet and dual-mode scramjet engine to operate at Mach 4 flight condition. The air intake was tested in the blowdown-type wind tunnel of Kyushu University to identify the internal flow characteristics corresponding to the flight parameters such as the back pressure, angle of attack and angle of yaw. Flow visualization was achieved by the Schlieren and oil flow visualization techniques. The intake performance was analyzed quantitatively based on the surface pressure and total Pressure measurements. The experimental results were compared with the computational fluid dynamics results. The present study exhibits the fundamental but rarely found experimental results of the high Mach number supersonic air intake.

We estimated the provenance of the obsidian artifacts from Samgeori site at Yeoncheon, one of the prehistoric sites in South Korea. Pyroxene microlites are of hedenbergite to augite compositions, and intergrown and/or overgrown with Fe-oxides showing poikilitic texture. Major oxides contents for the matrix of the obsidian artifacts exhibit a narrow compositional range, especially SiO₂ contents being 73.0~75.5 wt.% of acidic rhyolitic composition. Also, rare earth element (REE) contents are relatively constant in the obsidian artifacts, and the chondrite-normalized REE patterns show a strong Eu negative anomaly. These mineralogical and geochemical features of the Samgeori obsidian artifacts were compared with those from both the Baekdusan obsidians and Japanese Kyushu obsidians which have been thought to be two major obsidian provenances around South Korea. It is suggested that the Samgeori obsidian artifacts were possibly originated from the Baekdusan obsidians.
