전통마을숲인 당산숲 비보숲은 우리나라를 대표하는 전통문화경관(traditional cultural landscape)이며, 국가적문화자산이다. 중국의 feng-shui forest(풍수림, 風水林), 일본의 satoyama(里山), shinto shrine forest(신사림, 神祠林) 등은 '전통생태지식'(traditional ecological knowledge)으로서 국제적으로 널리 알려져 있다. 중국, 일본이 많은 연구 축적과 노력을 통해 유지 관리하고 있는 이러한 전통문화경관은 세계로부터 그 아름다움과 가치를 인정받고 있으며, 궁극적으로는 매력있는 관광자원으로 연결되고 있다. 마을주민들이 수백 년 간 대(代)를 이어 보전 관리해 온 한국의 전통마을숲 특히, 당산숲은 feng-shui forest와 satoyama에 필적하는 가치를 지니고 있다. 일반 시민들이 당산숲 비보숲이라는 이름과 그 실상을 잘 인식하고, 반드시 보전 관리 활용되어야 할 훌륭한 문화유산으로 간직한다면 중국, 일본의 예와 같이 세계적인 문화유산으로서 인정을 받을 수 있을 것이다. 완도군 서성리 당산숲은 마을 위쪽 산이 시작되는 경사면에 위치하고 있으며, 계류 옆에 위치한 수변림으로서 상록활엽수림과 서어나무 군락의 두 부분으로 이루어져 있다. 서성리 당산숲 공간의 특징은 당산제 후에 샘물, 당산나무 등 10곳에서 지내는 헌식제 공간에서 찾아볼 수 있다. 헌식제를 지내는 10곳 중 2곳은 해안가 쪽에 있는 당산나무로서, 해안 지역에 위치한 전통마을숲의 유형 측면에서 넓게 보면, 당산숲이 두 개 있는 유형에 속한다고 할 수 있다. 전통문화유산이 가치를 갖기 위해서는 새로운 축조, 파괴, 변형이 허용되어서는 안되고, 거기에 부여된 의미, 가치가 변질되지 않아야 한다는 진정성(authenticity) 측면에서 볼 때, 매년 음력 1월 8일 새벽 4시에 정확하게 시간을 맞추어 산신바위에서의 산신제 및 당집에서 당산제를 지내고, 당산제를 지낸 후 마을의 10곳을 찾아 헌식제를 지내는 완도군 서성리의 당산숲은 물활론(物活論, animism)을 철학적 기반으로 하는 우리나라 당산문화의 원형(原形)을 간직하고 있는 곳으로 판단된다. 문화유산의 보전 관리와 관련한 국제적 논의에서 중요시 하는 것이 문화유산 향유권의 지속가능성 여부이다. 그 존재가 부각되지 않은 채 방치되어 있는 실정의 서성리 당산숲 공간이 한국 고유 전통생태경관으로서의 가치가 인정되기 위해서는, 변형된 당집의 복구 등을 지원할 수 있는 사회 메커니즘과 당산숲에 대한 인식 제고가 필요하다.

The purpose of this study is to increase the use of Hwangto and examine the strength according to what it is compounded with. Hwangto-concrete containing Hwanto without cement nor organic chemical products were compared to the traditional cement concrete through some durability experiments. We expect to gain more knowledge on the potentials of Hwangto-concrete as an architectural source. 1) As Hwangto binder amount rises, the value of slump increases too. The reason is that the increase of the quantity of cement causes the increase of the amount of material and the decrease of the amount of aggregate. 2) When the mixed component into Hwangto-concrete remains at 2%, the compress strength is generally dispersed high along the per unit fission, in case the amount of which is at $400(g/m^3)$. The highest compress strength is 39MPa. It means that it can be applied to common structures and we need to conduct a basic property test to ensure the strength and fluidness. 3) Hwangto-concrete is expected to be highly used in the ocean structure and chemical industry because it has better resistance to sulfuric acid and to hydrochloric acid than the cement-concrete has. The result of this study is as follows. It is expected that Hwangto-concrete will be widely applied and further research on its durability and tests for its basic substantial characteristics based on future component added to it.

Leaf spot disease on black chokeberry (Aronia melanocarpa) was observed at several locations in Korea during 2014-2015. Leaf spots were distinct, scattered over the leaf surface and along the leaf border, subcircular to irregular and brown surrounded by a distinct dark color, and were expanded and coalesced into irregularly shaped lesions. Severely infected leaves became dry and fell off eventually. The causative agent was identified as Pseudocercospora pyricola. Morphological observations and phylogenetic analyses of multiple genes, including internal transcribed spacer, translation elongation factor 1-alpha, actin, and the large subunit ribosomal DNA were conducted. The pathogenicity test was conducted twice yielding similar results, fulfilling Koch's postulates. To our knowledge, this is the first report on P. pyricola infection of A. melanocarpa globally.

Several species classified to the genus Ulva are primarily responsible for causing green tides all over the world. For almost two decades, green tides have been resulted in numerous ecological problems along the eastern coast of Jeju Island, Korea. In order to characterize the species of Ulva responsible for causing the massive blooms on Jeju Island, we conducted DNA barcoding of tufA and rbcL sequences on 183 specimens of Ulva from eight sites on Jeju Island. The concatenated analysis identified five bloom-forming species: U. australis, U. lactuca, U. laetevirens, U. ohnoi and a novel species, U. pseudo-ohnoi sp. nov. Among them, U. australis, U. lactuca, and U. laetevirens caused to the blooms coming mainly from the substratum. U. ohnoi and U. pseudo-ohnoi sp. nov. were causative the free-floating blooms. Four species, except U. australis, are characterized by marginal teeth. A novel species, U. pseudo-ohnoi sp. nov., is clearly diverged from the U. lactuca, U. laetevirens, and U. ohnoi clade in the concatenated maximum likelihood analysis. Accurate species delimitation will contribute to a management of massive Ulva blooms based on this more comprehensive knowledge.

Recent ocean warming near the Korean peninsula and our lack of knowledge of an important vertebrate group, the sea snakes, encouraged us to clarify this part of Korea's regional fauna. We re-examined photographs that had been used to report the slender-necked sea snake (Hydrophis melanocephalus) in 1995. We discovered it was misidentified. To determine the correct identity of the sea snake, we studied 13 original photographs taken at the collecting site in Sooyoung Bay, Busan-si, in 1995 and determined the snake to be Laticauda semifasciata based on enlarged ventral scales, definitive for Laticaudinae sea snakes, and internasal scales, pale blue body color, divided rostral scale, and evident "V"-shaped stripes on the body trunk, definitive for L. semifasciata. Therefore, the snake caught 30 years ago in Korean waters should be considered the first record of a Laticaudinae sea snake in Korean waters. L. semifasciata is listed as near threatened setting the stage for urgently needed studies of sea snakes in Korea and supporting those currently underway.

Purpose: Reducing energy consumption and greenhouse gas emissions is a primary concern throughout the world, and the building sector is a particularly efficient area for making these reductions. In South Korea, the government has recently enacted policies for "Green Growth" that, among other things, enforce regulations in the building certification rating system (BCRS) and reorganize existing incentive systems. Method: In this study, we examined regulations and incentive systems used in the United Kingdom, Germany, and the United States that encourage the use of energy efficient technologies in construction and compared these policies to those used in South Korea. We also disseminated surveys to experts in the fields of architecture, planning and design, and engineering to better understand their knowledge and perception of the BCRS and its incentive systems. Additionally, we sought their recommendations for improving these incentive systems. Result: Based on our comparative case studies of regulations and incentives in other countries, alongside recommendations from experts in South Korea, we concluded that incentive systems in South Korea are limited and require improvement. We make recommendations for strengthening existing regulations and incentives and for implementing new incentive programs.

Purpose: The concept of the tectonic has researched to find out the identify of modern architecture. The meaning of traditional tectonic knowledge to emphasize structural joints and attention to detail in creativity has developed in various ways in contemporary architecture. The purpose of this study is to analyze the tectonic characteristics and architectural expressions of the light appeared in the works of Santiago Calatrava. Major features in his works could be found is to maximize structural beauties through deducing the architectural images from the nature and expressing the material properties and the kinetic structures, and thus, to ultimately create the functional space and form by connecting the light to the tectonic structure. Method: Accordingly, I tried to analyze the three works of Santiago Calatrava (the Milwaukee Art Museum, the Bodegas Ysios Winery and the City and Arts and Sciences) as following categories - the structural aesthetics, the expression of material properties, the relationship between he kinetic structures and the light. Result: According to the results of the study, Santiago Calatrava tried to create his own architectural aesthetic by combining structural tectonic with nature, material, regional place and culture. He also sought to express the tense and dynamic tectonic rather than the stable one in his works.

response to the global city. It was developed to cope with the decline of the manufacturing industry, a rise in unemployment and a welfare state system in danger. In cities of the concept, there has been much change in existing urban space and accordingly wisdoms and knowledge has been accumulated. The purpose of this research is to scrutinize urban spatial modification of a regenerated model city "Bologna". The target area of analysis was a ex-factory ailing district. Field site visit, deep interview with professionals and citizens, walk through observation, and historial literature review on the site were employed. As results, its history, retrofit process and current change were systematically described. The results showed ways of thinking, attitude toward historic preservation, technology, and creativity of using existing buildings for contemporary functions. This has a significant implication on Korean urban development which mostly, has ignored the existing value of community and buildings.

As arising concerns on environment, the social and institutional efforts have been made to establish green building in Korea. Even though the progress until now could not be underestimated, the education and information system of green architecture needs to be reconsidered. The system and the program of USGBC to cultivate green design and construction in the USA could be a good case to be explored. The results of exploration of USGBC programs are followed. First, USGBC is industry-led and consensus driven coalition and has diverse membership including building owners, architects, engineers, general contractors, government agencies and nonprofits. Second, various education programs are developed and provided not only for building industry practitioners but also for general people. Third, LEED Accredited Professionals who have detailed knowledge of LEED project certification requirements and processes are produced to make rating system go on smoothly and spread out. Forth, there are international conference and expo called "Greenbuild" and chapter events to interchange of information on green building industry. Lastly, there are incentives which are earning continuing education credits for other organizations such as AIA for attending a LEED workshop and earning a project one point towards LEED Certification. In view of above results, USGBC and its education program can be a good reference for developing ours on green building in Korea.
