  • Leaf and petiole explants of Pulsatilla koreana NAKAI were cultured on MS medium supplemented with various concentrations of zeatin, kinetin or BAP combined with 0.05 mg/L IAA. After 6 weeks of culture, effects of cytokinin on adventitious shoot formation from explants were investigated. The highest frequency of shoot formation was obtained when petiole explants were cultured on medium with 0.5 mg/L zeatin and 0.05 mg/L IAA. Regenerated shoot were transferred on to root induction medium. The best root formation was observed at 1/2 MS medium with 1.5 mg/L NAA. Rooted plantlets were transplanted to a mixture of perlit and soil (1:3), where they were successfully acclimatized.

  • 본 연구는 대구시에 거주하고 있으며 경제적 사회적으로 안정된 지위에 있는 저명인사의 거주지를 지표로 하여 사회지역 분석을 시도하였다. 이 들 저명인사 거주지역의 변화특성은 저명인사의 기존밀집지역인 중구와 남구는 감소하고, 수성구에 현저한 증가를 보인다. 이것은 이 기간동안 이 지역에서 꾸준히 추진된 택지개발과 학교 등 공공용지의 이전에 따른 고급아파트 지역의 형성의 영향이 크다. 그리고 교통, 생활 편익 시설의 상태외에 주거입지결정인자로서 주요한 위치를 차지하는 소위 교육여건이 유리한 학군이 저명인사의 분포에도 상당한 영향을 미친 것으로 판단된다. 이들 지역중에도 시간이 경과함에 따라 기존건축물의 노후화와 시가지의 외곽확대, 전원주택의 선호 경향 등의 변화에 따라 저명인사의 밀집현상은 다소 완화될 것으로 전망된다.

  • Background: Artesunate, extracted from Artemisia annua, has been proven to have anti-cancer potential. Allicin, diallyl thiosulfinate, the main biologically active compound derived from garlic, is also of interest in cancer treatment research. This object of this report was to document synergistic effects of artesunate combined with allicin on osteosarcoma cell lines in vitro and in vivo. Methods: After treatment with artesunate and allicin at various concentrations, the viability of osteosarcoma cells was analyzed by MTT method, with assessment of invasion and motility, colony formation and apoptosis. Western Blotting was performed to determine the expression of caspase-3/9, and activity was also detected after drug treatment. Moreover, in a nude mouse model established with orthotopic xenograft tumors, tumor weight and volume were monitored after drug administration via the intraperitoneal (i.p.) route. Results: The viability of osteosarcoma cells in the combination group was significantly decreased in a concentration and time dependent manner; moreover, invasion, motility and colony formation ability were significantly suppressed and the apoptotic rate was significantly increased through caspase-3/9 expression and activity enhancement in the combination group. Furthermore, suppression of tumor growth was evident in vivo. Conclusion: Our results indicated that artesunate and allicin in combination exert synergistic effects on osteosarcoma cell proliferation and apoptosis.

  • At the present stage of the world economic development, a new economic system is being formed, in which non-economic values, in particular environmental and social parameters, have become widespread. A new vision of economic activity is being formed, which acquires the qualities of Smart-economy. The purpose of this paper is reveal the features of managing the development of smart cities as specific entities of the Smart-economy. New functions of economic entities are formed within the framework of the Smart-economy concept, while their role and weight in the localities' activity or formation have changed. Determining that the key trends in the Smart-economy development are such as digitalization, greening, socialization, institutionalization, and urbanization, this is necessary to note that all these trends are most active in the formation of urban ecosystems. These trends are determined by the general population growth and the urban population growth, which requires considerable attention to planning each city's development itself. Such planning could ensure the comfort of living for all its inhabitants, quality, safe, and modern life. The Smart-city's key elements and the intellectualized approach implementation planes to the decision of these or those tasks are definedIt is determined that a new ecosystem of governance is being formed.

  • 본 연구의 목적은 최근의 경제 환경 변화 속에서 도시성장을 설명하는 새로운 모형으로 대두된 네트워크 도시를 심층적으로 이해하는 것이다. 이를 위하여 1990년대 중반 Batten(l995)의 시론적인 네트워크 도시 연구로부터 출발하여 현재에 이르기까지 관련 연구들을 정리하고 궁극적으로 네트워크 도시이론의 다양한 측면, 즉 형성과정, 공간구조, 관리 및 도시계획에의 응용, 성장에 대한 전망 등을 고찰해 봄으로써 네트워크 도시이론이 21세기의 도시현상을 설명하는데 적절한 이론인지에 대한 판단을 위해 필요한 포괄적인 지식을 제공하고자 한다. 관련연구들을 분석해본 결과 네트워크 도시는 경제의 세계화와 교통 및 정보통신기술의 발전과 함께 수반된 도시현상의 변화를 적절히 설명해 주는 이론일 뿐만 아니라 유럽을 중심으로 여러 도시정부들이 도시계획원리로 적극적으로 수용해 나가는 추세에 있는 유용한 개념으로 판단된다.

  • 본 연구는 인천시 도시구조의 특성을 제시하고, 도시구조의 재편과 효율적 운영을 위한 전략을 제시하는 것을 목적으로 하고 있다. 인천시는 인구증가와 함께 지속적인 외곽으로의 평면적 확산이 진행되고 있다. 대규모 개발사업에 따른 새로운 주거지로의 인구이동이 활발해짐으로써 기존 시가지의 쇠퇴가 두드러지는데 반해 시 외곽지역에 많은 인구가 집중하고 있는 추세이다. 인천이 추구해야 할 표시구조 재연의 기본 방향으로 네트워크형 도시구조 창출, 개발지정구역의 설정, 도심재활성화를 위한 발전축 조성, 생활권 중심지 개발을 제시하였다. 인천시의 도시구조 운영전략으로는 국제지향적 단지개발, 새로운 거점과 발전축 조성, 전문테마거리 조성을 통한 특화지향적 개발, 세계도시형 표시로의 성장을 위한 네트워크형 개발, 지역생활권 중심개발을 제안하였다. 이를 통해 인천의 안정적인 발전과 주민의 삶의 질 향상을 위한 마스터플랜을 수립하고 효율적인 도시구조 음영전략을 수립하는데 기본적인 틀이 마련될 수 있도록 하였다.

  • This thesis is a study to Haengnang(行廊, a series of buildings) of Sijeon(市廛, licensed markets), which was built along with palaces, Jongmyo(宗廟) and roads in order to establish Hanyang(漢陽) as the capital of Joseon (朝鮮). Sijeon, built on Jongno and Namdaemun-ro, the main roads in Hanyang, created two-row lands on both sides of the road, and formed Pimat-gil as an inner road between the Jeonbang and Doga. The formation of the city proceeded along with the maintenance of the water path, and the situation of the water path parallel to the flow of Sijeon was achieved. The Sijeon building was a spatial structure managed by independent rooms as a result of reflecting the unique operation method of Sijeon. The Sijeon of Hanyang had an impact on the formation of land, architecture, roads, and waterways, and acted as a major factor in determining the urban spatial structure of Hanyang City.
