  • The purpose of this paper is to research Gunnar Asplund's Woodland Chapel (1918-20) in terms of the revernacularization of classicism and to investigate into the matter of the constructional logic. The term 'revernacularization of classicism' was used by Alan Colquhoun to explain the process to return to the pure sources of classical architecture, and the case of a successful fusion of classicism and vernacular traditions was suggested by Demetri Porphyrios through Scandinavian Doricist sensibility in the early 20th century. Porphyrios's classicism, not as style but as sensibility, is premised on a constructional logic of vernacular, and is to achieve an aesthetic quality by its mythical elaboration. Woodland Chapel, a representative of the Scandinavian Doricism according to him, illustrates characteristics of the revernacularized classicism as in the fact that it thickly displays vernacular images at the same time as relying on classicism; in the return to primitive simplicity; and in the mythopoeic power. However, the constructional logic of this building was obscured in the capital of the portico columns, the interior dome, and the whole structure of the roof. Confronting this paradox, we have to remember that although Porphyrios emphasized the constructional logic he opened an aesthetic exit of the mythical elaboration, which is in accord with the concept of the tectonic as the poetics of construction. Woodland Chapel assumes atectonic features but is never anti-tectonic. Asplund intensified a poetic effect by setting the myth over construction in the chapel, and so it can be seen as a key example of the revernacularized classicism with the Doricist sensibility.

  • Molluscs from the Neolithic shell middens (Sugari, Pudjeong, Tongsamdong, Sangnodaedo, Sandeung, Yondaedo, Songdo and Kupyongri) in the southern coast, Korea, consisted of marine, fresh-water and land molluscs. Among these, intertidal species were exploited most abundantly as food resources, indicating a high dependence of intertidal shellfish collection activities. Especially oysters were the most abundant in these sites except Tongsamdong where mussels were predominant, indicating oysters were the most important food resources. Land snails from the sites consisted of woodland and open land species. Woodland species were more abundant than openland species, suggesting that there was a woodland environmint around the sites. Marine and land mollusc species from the sites are common in these rigions today, indicating no large-scale emvironmental changes have occurred since these middens formation period.

  • 우리나라는 '산림복지'를 정식으로 정책 대상에 포함시키거나 학술용어로 활용하고 있으며, 산림청은 출생부터 사망까지 각 생애주기에 적합한 산림복지서비스를 제공하기 위해 노력하고 있고, 국민들도 산림복지서비스 및 정책의 필요성을 높게 인식하고 있다. 수목장을 비롯한 자연장에 대한 관심이 증가됨에 따라 국유수목장림의 수요는 증가할 것으로 예상된다. 수목장림의 선호도가 높아짐에 따라 수요가 증가하고 있지만, 국립 수목장림은 1개소에 불과하다. 자연휴양림 등 다른 산림복지시설들은 지정 또는 조성계획 승인 전에 관련법에 따른 타당성 평가를 거치지만, 수목장림은 타당성 평가 등의 제도는 마련되어 있지 않았다. 따라서 수목장림에 대한 사회적 수요 증가에 대응하기 위한 정책을 강구할 필요가 있으며, 이에 본 연구는 수목장림 적정입지를 선정하는 과정에서 활용할 수 있도록 기초자료를 마련하기 위해서 GIS를 활용해 법적 제한지역을 분석하고, 국유림 내 수목장림 입지 가능지역 규모를 파악하였다.

  • 초지조성과 개량에서 겉뿌림은 중요한 방법 중의 하나이다. 오늘날 겉뿌림 초지조성에서 종자피복기술은 관심이 높아지고 있다. 따라서 본 시험은 산지초지에서 겉뿌림조성시 목초의 출현율과 정착율을 높이기 위해 화본과목초종자의 피복기술을 개발하기 위하여 실시하였다. 종자 펠렛팅은 피복시간을 단축하고 단위시간당 피복량을 증가시킴으로서 종자피복의 새로운 기술로 평가되었다. 펠렛종자의 건조시간을 단축하고 건조온도를 낮춤으로서 화본과 목초종자의 발아세와 발아율이 증가하였다. 임간초지에서 펠렛종자는 종자의 출현, 정착 및 초기생육을 향상시켰다. 이상의 시험결과를 볼 때 임간초지에서 종자 펠렛팅 기술은 화본과목초의 정착과 초기생육 향상을 위한 새로운 기술로 평가되었다.

  • 본 연구는 서부 호주의 Durokkopin 자연 보호 구역에 서식하고 있는 흰개미의 개미집과 서식밀도를 조사하기 위해 수행되었다. 조사결과 Woodland에서의 흰개미 집의 분포와 서식밀도가 Shrubland보다 월등히 높았으며, 일부 흰개미집의 경우 조사기간인 14개월 동안 크기가 감소한 것으로 조사되었으나, 일반적으로 조사기간 중 흰개미 집의 크기 변화는 거의 없었으며, 계급별 구성비율 또한 거의 변화가 없는 것으로 조사되었다. 그러나, 흰개미 개체수는 개미집이 작을수록 증가율이 높은 것으로 조사되었다. 본 연구결과를 토대로 종합해 보면, 두 조사지역 중 Wooldland가 Shurubland보다 공시 흰개미인 Drepanotermes tomminensis (Hill)에 보다 나은 서식처를 제공하는 것으로 사료된다.

  • Although economically viable, the livestock industry is currently facing a number of challenging environmental problems and highly complex social issues, many of which are related to its size and geographically concentrated nature. Increased emphasis on environmental quality has also placed new demands on livestock producers to ensure that their production practices are in harmony with natural environment. In terms of sustainable agricultural systems, ruminants have served and will continue to serve a valuable role. They are particularly useful in converting vast renewable resources from rangeland, pasture, and crop residues or other by-product into food edible for human. With ruminants, land that is too poor or too erodable to cultivate becomes productive. Also, nutrients in by-products are utilized and do not become a waste-disposal problem. In Korea, however, native and dairy cattle production is not consistent with the advantageous roles of ruminant livestock in sustainable agricultural system because imported feed grains become the main basis for cattle raising. At present the ruminant livestock producers are heavily concentrated in and around the urban areas. About 75% of all the nation's cattle herds are kept on the outskirts of urban areas. As a result, the amount of pasture and forage land available per head of cattle is generally small. Furthermore, animals are raised in a cattle shed with high density. This situation is rather unfavorable for the national economic and environmental points of view As nation income increased, the demand for livestock products grew at an unforeseeable pace. But the pasture area involving in current utilization is tended to decrease during recent years. Based on the above figures more than 250,000 ha of pasture ought to be available for the present herd of cattle. It is obvious that these needs can scarcely be met with arable lands. Lands area for the establishment of new grassland have to be found in the hills and mountains which have not yet been used for crop framing or livestock. The development of extensive grasslands in the hill and woodland areas is now a declared aim. The starting point of the present work is the lack of knowledge of forage production and utilization in hill pasture and woodland in spite of indispensable necessity for livestock production in Korea. The importance of pastoral system in hill region and woodland is particularly emphasized in a standpoint of sustainable livestock production. Main chapter comprises the principle and techniques applicable for improving the utilization of hill pasture and woodland. We finally discussed the problems to solve and future works for a successful livestock production in hill and mountainous area in Korea.

  • For last 150 years, blackbirds have moved from their ancestral habitat, the woodland edge, to man-made habitats such as farmland, parks and gardens. These alternative habitats have become one of main blackbird habitats. I compared density of nests and blackbirds in parks, woodland and campus of University of East Anglia to investigate habitat preference. Blackbirds preferred the area covered by $10\sim50%$ of tree or bush patches for their foraging and nesting sites. Blackbirds were more frequently found near buildings rather than far from buildings. Nest characteristics did not affect predation rate and nest preference. This study suggests that man-made habitats may be important for avoiding predation.

  • In Ethiopia, dry land vegetation including the fairly intact lowland and western escarpment woodlands occupy the largest vegetation resource of the country. These forests play a central role in environmental regulation and socio-economic assets, yet they received less scientific attention than the moist forests. This study evaluated the woody plant species composition, population structure and carbon sequestration potential of the A. senegal woodland across three distance gradients from the settlements. A total of 45 sample quadrants were laid along a systematically established nine parallel transect lines to collect vegetation and soil data across distance gradients from settlement. Mature tree dry biomass with DBH>2.5 cm was estimated using allometric equations. A total of 41 woody plant species that belong to 20 families were recorded and A. senegal was the dominant species with 56.4 IVI value. Woody plant species diversity, density and richness were significantly higher in the distant plots compared to the nearest plots to settlement (p<0.05). The cumulative DBH class distribution of all individuals had showed an interrupted inverted J-shape population pattern. There were 19 species without seedlings, 15 species without saplings and 14 species without both seedlings and saplings. A significant above ground carbon (5.3 to 12.7 ton ha-1), root carbon (1.6 to 3.6 ton ha-1), soil organic carbon (35.6 to 44.5 ton ha-1), total carbon stock (42.5 to 60.7 ton ha-1) and total carbon dioxide equivalent (157.7 to 222.8 ton ha-1) was observed consistently with an increasing of distance from settlement (p<0.05). Distance from settlement had significant and positive correlation with species diversity and carbon stock at 0.64⁎⁎ and 0.78⁎⁎. Disturbance intensity may directly influence the variation of species composition, richness and density along the A. senegal woodland. The sustainability of the A. senegal woodland needs urgent protection, conservation and restoration.
