  • 종간 유연관계 및 속의 이해를 돕기 위하여 Ocotea속의 과실 해부형태의 연구가 14종에 대하여 수행되었다. 조사된 종들간의 과실해부형태는 거의 비슷했으나 종들간 차이는 중과피내에 후벽세포의 유무에 있었고, 만일 중과피내에 후벽세포가 존재한다면 어느부위에, 또는 어떠한 형태로 존재하는가에 달려있다. 조사된 종들을 가지고 비교한 결과, Ocotea속은 적어도 5개의 group으로 나눌 수 있었다. 즉, 1) 후벽세포가 발달하지 않은 종 O. atrriensis, O. cujumari, O. helicterifolia, O. rubra and O. schomburgkiana; 2) 후벽세포가 외하피에만 발달한 종 O. aciphylla, O. javitensis, and O. sp. [Werff et al. 12676]; 3) 후벽세포가 내하피에만 발달한 종 O. tonuzii; 4) 후벽세포가 외하피와 내하피에 모두 발달한 종 O. foerens, O. quixos, and O. veraguensis; 과 5) 후벽세포가 중과피의 여기저기에 발달한 종 O. floribunda and O. nitida으로 나눌 수 있었다. 아울러, Ocotea속에 있어서 과피 해부형태의 다양성이 논의되었으며, 속에 대한 분류학적 재인식이 요구되었다. 한편, 과실의 해부형태 형질의 진화경향은 중과피내에 후벽세포가 발달하지 않은 종으로부터 후벽세포가 발달한 종으로 진화했을거스로 추정되었다.

  • 본 연구에서는 CO2 고정화 탈황석고(CFBG)의 건조온도에 따른 기초 물성 및 슬래그 시멘트의 자극재로 활용 가능성을 검토하였으며, 콘크리트 배합 시험을 통한 성능평가를 진행하였다. CFBG의 주요 성분은 CaO 및 SO3로 나타났으며 건조온도가 증가함에 따라 CaO 및 SO3가 증가하였다. 미건조 CFBG는 함수율이 15.7 %로 나타났으며 건조온도 85 ℃는 1.7 %, 105℃ 는 0.03 %로 나타났다. CFBG를 사용한 모르타르는 건조온도 증가에 따라 플로값이 저하하는 경향이었으며 압축강도는 FGB 사용 배합과 동등 수준을 나타냈다. CFBG SC를 사용 콘크리트 실험 결과 슬럼프 및 공기량은 60분 경과 후 모두 목표 범위를 만족하였으며, 압축강도는 일반 3성분계 배합 대비 전반적으로 증가하는 경향이었다.

  • In order to investigate the offshore wind resources, the "QuikSCAT Level 3" data by the QuikSCAT satellite was analyzed from Jan 2000 to Dec 2008. QuikSCAT satellite is a specialized device for a microwave scatterometer that measures near-surface wind speed and direction under all weather and cloud conditions. Wind speed measured at 10 m above from the sea surface as extrapolated to the hub height by using the power law model. It has been found that the high wind energy prevailing in the south sea and the east sea of the Korean peninsula. From the limitation of seawater depth for piling the tower and archipelagic environment around the south sea, the west and the south-west sea are favorable to construct the large scale wind farm. Wind map and monthly variation of wind speed are investigate at the positions.

  • UNESCO is an international specialized agency based on the United Nations (UN) located in the Paris. The United Nations Educational, Scientific and Cultural Organization abbreviated as UNESCO. The mission and goal of UNESCO are to maintain the peace and security throughout the globe by encouraging international collaborations through educational, scientific, and cultural heritage in order to increase respect for principals of justice, international rules of law, and international human rights. Recently, the UNESCO published a new set of 17 goals for the nation's sustainable society. The Organization ensures to actively participate in UN activities to improve harmony and planning within the United Nations system. The 2030 agenda is primarily about shifting the world on to a sustainable and most in-depth. Currently, UNESCO launched broad goals and objectives for the international community including the Millennium Development Goals (MDGs). Among these sustainable goals, climate change, water security is more significant. In this paper, we briefly reviewed the seventeen goals by UNESCO.

  • The objectives of this study are to provide advices and methods for cultivating labor in the digital cultural contents industry in the Chung-Nam Province. For the purpose of this study, review of theoretical and practical literature, identifying the present status of affairs, and three times FGI and surveys were executed. The results of research show a lack of professional labor in the digital cultural contents industry; even so most of laborers want to get a job in or around the Seoul region. To activate digital cultural contents in the local area, a development model for the Chung-Nam digital cultural contents industry was introduced and four strategies were also suggested. The nurture of a professional skilled labor force through a strategically designed joint relationship between university and companies in the digital cultural contents industry was found to be quite necessary. In this way, the need for specialized training and education in the university classroom can be supported.

  • Recently, local studies looking at the 'local(region) as a whole' are gradually increasing. The study of local architectural history is important in that it provides specific information that encompasses the local and the entire and clues to three-dimensionalize the time and space in the local. To infer the 'presentness' of each era, reliable data in various fields are needed. Recently, as many databases (DB) and archives, from the 'National Archives of Korea' to other local archives, have been established and publicized, research resources in the local are growing rapidly in quantity and quality. Nevertheless, it is difficult to comprehensively check the data necessary to study the local architectural history(local architectural history research resources). Against this background, this study confirmed the trend of changes in the archive construction environment and the status and problems of local architectural history research resources in places that currently disclose local history research resources among generalized web-archives. Next, the relationship between the actual research on local architectural history was confirmed through the analysis of existing studies and the data used for Jeju. As a result, local studies, local archives, and local architectural history research agree with recent changes in local research trends, and the degree of archival construction has reached the same level as the available research resources except core data in local architectural history research. However, there is a problem that the density of information that can be used is low because the local architectural history research resources that can be obtained are fragmented because there are no archives and construction entities specialized in local architecture. As each archive has entered the stabilization and upgrading stage, the construction of new archives needs to be reconsidered, but it is time to find a detailed way to link related information quickly and accurately, such as private records, to reduce the gap in information needed in terms of research on local architecture and architecture history.

  • The feeding habits of juvenile Chaenogobius annularis were examined based on gut content analysis of 281 individuals, collected from May to June 2011 in the coastal water of Geoje, Korea. Copepods were the main source of food for C. annularis, which constituted 61.6% in IRI. Barnacle larvae was the second largest dietary component. Graphical analysis of the diet composition showed that C. annularis was a specialized predator characterized by strong individual feeding specialization. Both small and large size class of C. annularis mainly consumed harpacticoida and cirripedia cypris.

  • Magnaporthe oryzae, the causal agent of rice blast, forms a specialized infection structure, called an appressorium, which is crucial for penetration and infection of the host plant. Pharmacological data suggest that calcium/calmodulindependent signaling is involved in appressorium formation in this fungus. To understand the role of the calcium/calmodulin-activated protein phosphatase on appressorium formation at the molecular level, MCNA, a gene encoding the catalytic subunit of calcineurin, was functionally characterized in M. oryzae. Transformants expressing sense/antisense RNA of MCNA exhibited significant reductions in mycelial growth, conidiation, appressorium formation, and pathogenicity. cDNA of MCNA functionally complemented a calcineurin disruptant strain (cmp1::LEU2 cmp2::HIS3) of Saccharomyces cerevisiae. These data suggest that calcineurin A plays important roles in signal transduction pathways involved in the infection-related morphogenesis and pathogenicity of M. oryzae.
