대면적 개벌의 대안으로서, 대상 개벌은 생산림지의 생태 조건 보전과 임분 재생을 모두 고려하는 작업법이다. 그러나 우리나라에서는 대상 벌채 기법의 적용 및 효율성에 대한 연구를 찾아보기 어렵다. 본 연구는 강원도 삼척에서 2012년부터 2014년까지 소나무림 대상 벌채 (10m, 20m 및 40m) 처리 전･후의 하층식생 반응 및 소나무 재생과 임분 환경 변화와의 상관성을 방형구법을 적용하여 조사 및 분석하였다. 하층식생 피도 및 종다양성은 대상 벌채 넓이에 상관없이 교목 종 및 광선호 종의 확장에 의해 증가하는 경향이었고, 신갈나무, 맑은대쑥 및 산딸기 등의 벌채 후 잔존 교목 및 광선호 종들의 활발한 증가가 관찰되었다. 대상 벌채 구역의 소나무 정착은 수관층 환경 (광량 및 수관열림 도) 및 토양나출도와는 정의 상관, 그리고 하층식생 및 임상 목질잔해물의 피도와는 음의 상관을 나타내었다.

본 연구는 산림 내에서 수종갱신 및 천연갱신 등의 산림시업을 실시한 이후 딱정벌레류 곤충분포상의 변화 양상을 군집수준으로 조사 · 분석하여 종다양성이 증대되는 시업방법의 구명을 통해 산림생물다양성 보전을 위한 효과적인 관리기법을 제시하는데 필요한 기초자료를 확보하고자 수행되었다. 이를 위해 2012년, 강원도 삼척군 하장면 일대의 소나무림 갱신임지 내에서 5개의 임업시업 방법별로 처리한 후 동일지점에서 2013년 7월부터 10월까지 딱정벌레류 곤충상 조사를 실시하였다. 조사 목적상 갱신임지 유형별로 딱정벌레류를 정량조사하기 위해 45일 간격으로 린드그렌퍼넬트랩을 이용하여 채집조사를 실시하였으며, 조사대상인 딱정벌레류의 분류군별 다양도 및 풍부도를 중심으로 분석을 실시하였다. 연구 결과, 딱정벌레류는 총 40과 156종 1,112개체가 조사되었다. 조사 초기 단계에서 각 처리방법별 뚜렷한 밀도차이는 나타나지 않았으나, 전 처리구들이 대조구에 비해 다양도 및 풍부도가 증가하는 경향을 보였고, 이 중 대상개벌을 실시한 구간에서 비교적 높은 밀도를 보이는 것으로 확인되었다.

This research aims at a critical discourse on the relation between the concepts of the uncanny and posthistoire , on the basis of descriptions in The Architectural Uncanny (1992) by Anthony Vidler. For the purpose, Histories of the Immediate Present (2008), another book by Vidler that discusses posthistoire philosophy to which he is not positive, is also investigated along with the former thesis; and various publications related to the themes by the influential writers such as Freud, Lyotard, Vattimo, and Habermas are referred to, too. Firstly, this paper will illustrate an essential understanding of the uncanny, an outgrowth of the sublime, and the history of posthistoire respectively; and then analyse contexts where the posthistoire was mentioned in The Architectural Uncanny. In the 'Introduction' and 'Losing Face' chapters of the book, this paper argues, the two concepts are connected by the notions of 'repetition' and 'losing the classical facade' as well as the uncanny as 'a metaphor for a fundamentally unlivable modern condition'. Though Vidler's recognition of posthistoire in the two chapters are differently interpreted, each as 'the emptiness of capitalism' and 'the decomposition of representation', both can be understood in terms of 'modernity' that is 'still open'. If modernity is 'an unfinished project' as maintained by Habermas, who Vidler relies on, we need to continue innovative experiments and internal investigations in architectural creation beyond the categories of modernism and postmodernism.

This paper aims at researching the cave concept of the Japanese architect Terunobu Fujimori and the result could be summarised as follows. First, a cave is Fujimori's only theme related to the interior space. He set some design guidelines for practice concerning openings of the wall and finishing materials of the interior, following the two major characteristics of a cave: 'comfortability' and 'homogeneity in material'. And 'fire' was also the premise in the cave as a 'spirit' of the space. Second, Fujimori applied the concrete guidelines to Tanpopo House (1994~95), which had in fact borne the ideas. Yakisugi House (2005~07) that took the cave as its design theme showed the transition of his cave concept, from closedness to openness. Third, though his cave concept might deserve the criticism that it is inclined to 'image' rather than 'essence', it illustrates that he seeks after an archetype of human dwelling before the purity of the original space was tarnished with rationality and abstraction. And the cave idea allows the seemingly contradictory 'sachlich' and 'surrealistic' features to coexist. Summing up, Fujimori's cave concept proves that his architecture is a rejection of the Cartesian modernist ideal and the contemporary architects' desire for dematerialisation. In a fundamental level, however, it is a result of his strategic choice induced by his own primary principle that his building must not be similar to any styles in history or any other architects' works in the world.

This study was conducted to determine the growth performance and carcass characteristics of fattening Hanwoo heifers slaughtered at different ages. Twenty one Hanwoo heifers were randomly allocated to three groups (32, 36 and 40 months age), with 7 steers each, respectively. In the result, initial and final body weights were 125.6 and 651.0 kg, respectively. Average daily gain was significantly low at final stage compared with other growth stages (p<0.05). Dry matter intake was the peak at the intermediate fattening stage (p<0.05). The feed conversion ratio was significantly lower at growing stage compared to other stages (p<0.05). In yield traits, carcass weight was greater in 40 months age group compared to other groups (p<0.05). Yield index was greater in 32 months group compared to 40 months of age (p<0.05). Marbling score, meat color, fat color, texture, and maturity were not different among groups (p>0.05). However, marbling score tended to be increased in 40 months age group (5.9) compared to other groups. The appearance rate (%) of meat quality grade more than 1+ was greater at 40 months old group than other groups.

This study was conducted to investigate the effects of Chromium-Methionine (Cr-Met) chelate feeding for different durations on growth and carcass characteristics in the late fattening stage of Holstein steers. Nine Holstein steers were randomly assigned to three dietary treatments (3 head per treatment) including Non Cr-Met chelate feeding (NCM, av. BW of 433.3 kg), Cr-Met chelate feeding for 2 months (2CM, av. BW of 459.6 kg), and Cr-Met chelate feeding for 4 months (4CM, av. BW of 490.0 kg), respectively. The feeding amount of Cr-Met chelate to an animal was limited to 400 ppb/day. Dry matter intake showed no differences among all the treatments (p>0.05). Average daily gain was also higher in the animals fed Cr-Met chelate diets than NCM (p<0.05). Carcass weights were also observed to be higher in Cr-Met chelate feeding treatments, especially in 4CM compared with other treatments (p<0.05). Although no significant differences were observed on back fat thickness and rib eye area(p<0.05), but 4CM showed much higher effects than NCM and 2CM. Marbling score meat color, fat color, texture, and maturity were not affected by treatments (p>0.05). The variations in meat quality were smaller in 4CM compared to other treatments. 4CM showed higher total and net income than other treatments (p<0.05). Therefore, the current study concluded that Cr-Met chelate supplementation for 4 months could increase daily gain, carcass characteristics, and profitability of Holstein steers in the late fattening stage.

본 실험은 조사료와 농후사료비율(조:농비)에 따라 low forage (LF)구 및 high forage (HF)구로 나누어 Holstein 착유소(초산) 10두를 각 5두씩 배치하여 실시하였다. LF구는조:농비가 37:63로 BIRG 사일리지와 혼합건초를 포함한조사료의 급여량을 줄인 반면 농후사료를 다량 급여하였다.HF구는 조:농비가 62:38로 농후사료 급여량을 줄인 반면BIRG 사일리지와 혼합건초를 포함한 조사료를 다량 급여하였다. 평균 조사료섭취량은 LF구 7.1및 HF구 13.0 kg으로 HF구에서, 평균 농후사료 섭취량은 LF구 12.3 및 HF구7.9 kg으로 LF구에서 유의적으로 높았다(p<0.05). 총 사료섭취량은 LF구 19.4 및 HF구 20.9 kg으로 HF구에서 높은경향을 보였으나 유의적인 차이는 없었다(p>0.05). CP,TDN 및 NEL 섭취량은 두 처리구간에 유의적인 차이는없었다(p>0.05). 실제 산유량은 LF구 26 및 HF구 23.9 kg/d으로 처리 간에 유의적인 차이는 없었으나(p>0.05) LF구에서 높은 경향을 보였다. 4% FCM은 LF구 22.8 및 HF구22.3 kg/d 으로 유의적인 차이는 없었다(p>0.05). HF구에서유지방 함량은 높고 MUN 함량은 낮았다. 우유의 C14:0,C16:0 및 C16:1n7 함량은 HF구가 LF구 보다 유의적으로높았으나(p<0.05), 그 외의 우유지방산은 두 처리구간에 차이는 없었다. 이상의 결과로부터 본 연구에서와 같이 급여사료 중 BIRG 사일리지와 수입건초와 같은 조사료를 적절하게 배합하여 다량급여 하여도 착유소(초산우)에 필요한영양소 충족이 가능하여 산유량의 감소가 없는 것으로 사료된다.

This paper aimed at investigating into the origin and meaning of the Japanese architect Terunobu Fujimori's 'piercing column', and drew a conclusion as follows. First, the piercing column that made its first appearance in his architect debut work Jinchokan Moriya Historical Museum (1991) was conceived unexpectedly from pencil lines on a sketch that went through over the building's roof. And the tree-like natural treatment of the column's surface was influenced by Takamasa Yoshizaka's description of a Mongolian mud-house. Second, most of piercing columns in his later works have nothing to do with a structural role as in Jinchokan, but were designed for a visual effect and as a symbolic gesture. Again, they allude to a tree in nature through a roughly peeling treatment of the surface. Third, considering his ideas in History of Humankind and Architecture (2005), his column could be related to a universal origin of architecture and a symbol of the sun-god faith, and in particular to independent columns of Japanese Shito shrines, such as 'Onbashira' in Suwa and 'Iwanebashira' in Izumo. That is to say, the Fujimori column is a medium that implies the animistic nature-faith of Japan. Nevertheless, Fujimori's naturalism hints at a disquieting quality through an intentional artificiality and a provocative conflict between structure and finish of a building, which might be one aspect of the modern condition, 'uncanny'.

The purpose of this paper is to trace the architectural origin of the Bosung College Library (1935~37), which is currently used as Graduate School Building of Korea University. So far, numerous books have repeatedly described that the library was modelled on a Duke University library, but without any serious consideration. Through literature review, field-trip and archives investigation, this research discovered new critical facts concerning the origin of the building. First, Dong-Jin Park, the architect for Bosung College, saw a photograph of the Duke library in a Duke University catalog possessed by Chun Suk Auh, Professor of the college at that time. Second, the Duke library that he saw in the catalog, which might possibly be Bulletin of Duke University (Feb. 1931), is certainly the present Perkins Library (1930) in Duke University West Campus. Third, the architect probably referred not only to the library but also to other Duke buildings such as School of Medicine and The Union, of which photographs were also published impressively in the Bulletin. Although the Bosung College Library was inspired by the Duke buildings, however, it is undoubtedly a creative design work by the architect Park. Arguably, these findings broaden our view of Korean architectural history in the modernization period, and it is more than a confirmation of just one building's origin.

This study was carried out to investigate the effect of muscle part and aging period on free amino acids and aroma compounds of Hanwoo (Korean cattle) cow beef. The M. longissimus (ML) and M. semitendinosus (MS) from 101 mon-old-cows were aged at 2℃ for 14 d. The free amino acids concentration increased in both ML and MS on 14 d of aging. In ML, asparagine, glutamine, histidine, glycine, threonine, arginine, tyrosine, phenylalanine, isoleucine, leucine and lysine were significantly (p<0.05) higher than those in MS. Varieties of aldehydes, ketones, alcohols, hydrocarbons, nitrogen and sulfur compounds were detected in both ML and MS and majority of these compounds showed increasing trend on aging. The ML had higher 14 aldehydes (acetaldehyde, 2-methylpropanal, 3-methylbutanal, 2- methylbutanal, pentanal, hexanal, heptanal, E-2-heptanal, octanal, 2-octenal, 2-nonenal, E-2-decenal, E,E-2,4-decadienal and 2-undecenal), 5 ketones (2-propanone, 2,3-butanedione, 2-butanone, 2-heptanone and 2,3-octanedione), 4 alcohols (ethanol, 1-pentanol, 1-hexanol and 1-octanol), 3 hydrocarbons (3-ethyl-2-methyl-1,3-hexadiene, 3- methyldecane and 2,2-dimethyloctane) significantly (p<0.05) compared with MS. However, the MS had higher 5 nitrogen and sulfur compounds (methanethiol, dimethyldisulfide, fufural, 2,5-dimethylpyrazine and 2-octylfuran) significantly (p<0.05) compared with ML.

We investigated the effect of glutathione supplementation on feed intake, body weight loss, behavior change and economic analysis of elk bull in breeding season. Sixteen elk bulls (5-year-old, average weight; 330 kg) after antler cutting were divided into 2 groups. Eight bulls in each group (control and glutathione group) were fed experimental diet at a level of 0.85 percent of body weight and 6 mg glutathione per kg body weight. As a result, weight-loss of control animal during experimental study (from September to November) was 42.6±19.2 kg while that of glutathione-supplemented group was 20.6 ±19.9 kg. Compared to control group, glutathione-fed group had prevented the body weight loss by 5.2% (p<0.05). Although the feed intake of elk voluntarily decreases during breeding season, daily DM intake per head was 5.59 and 5.80kg in control and glutathione-fed group, respectively. While the statistical difference in feed intake between two groups was not observed, feed intake tended to increase in glutathione-fed group. In economic analysis, additional cost of 99,000 KRW per head was spent due to the cost of glutathione because of its import. Changes in behavior such as crying, deer whistles, whistling intensity and frequency of accident were lower in glutathione-fed group compared to control. During breeding season, use of glutathione as feed supplement could suppress body weight loss and accidents in deer farm.

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.

본 연구는 허브 부식토를 이용하여 첨가 수준별 in vitro 반추위 발효특성 평가와 젖소를 이용하여 급여시 유생산성에 미치는 영향을 조사하기 위하여 본 연구를 수행하였다. 시험 1에서는 티머시 건초를 기질로 하여 허브부식토(herbaceous peat)를 0,1 및 5%를 3반복으로 각각 첨가하여 in vitro 반추위내 pH, 가스발생량, VFA (volatile fatty acid), ammonia-N 및 건물분해율을 조사하여 반추위내 발효성상의

The study was conducted to investigate the differences in the compounds responsible for volatile flavors in Hanwoo and imported fresh beef from Australia, United States and New Zealand. Different imported beef samples were prepared as Angus beef from Australia, United States and New Zealand and the cross beef from the United States. Significant differences (p<0.05) in hexanal, benzaldehyde, octanal, nonanal, nonenal, decanal, E-2-decenal, hexadecyloxirane, tetradecanal, 2,2-dideutero octadecanal, octadecanal, pentadecane, 2,5-dimethyl pyrazine, 4-methyl-2-propyl-furan, 2-hexylfuran, 2-butylfuran, 2- pentylfuran, 2-heptyl furan were observed between loin and eye of round from Hanwoo and imported beef (p<0.05). In loin muscles, various volatile compounds such as hexanal, heptanal, octanal, E-2-octenal, nonenal, E-2-decenal, E,E,2,4-decadienal, 2-undecenal, heptane, 2-butyl furan were found to be significantly higher in Hanwoo beef as compared to imported beef. However, in the round muscles of Hawnoo eye compounds that were observed to be significantly higher were pentanal, hexanal, heptanal, benzaldehyde, octanal, nonanal, E-2 -decenal, octadecanal, 2-furan methanol and 2-pentyl furan. Further study need to be determined if those volatile compounds can be used as a bio-marker to identify origins of beef.

This study is conducted to screen compounds affecting ruminal fermentation under in vitro incubation. Saponin, chitosan, metformin, zinc acetate, zinc chloride, zinc oxide, zinc sulfate, ascorbic acid, oil-coated ascorbic acid, nicotinic acid, eastern herb cocktail, charcoal extract and garlic sources (lyophilized and extract) were added to rumen culture fluid at 1.25% of substrate (100% timothy) volume at 24 h incubation. pH, total gas, ammonia, VFAs were measured. Ascorbic acid increased total gas production indicating fermentation level. All zinc compounds significantly decreased (p<0.05) although zinc sulfate increased propionate of volatile fatty acid (p<0.05). In following experiment, ascorbic acid, oil-coated ascorbic acid, garlic lyophilized, herb cocktail and zinc sulfate were added to rumen culture fluid at 2.5% of substrate with 3, 6, 12 and 24 h incubation. Zinc sulfate decreased both ruminal fermentation and VFAs production but ascorbic acid enhanced total gas production. Ascorbic acid increased fermentation regardless of supplement concentration although excessive zinc sulfate decreased fermentation. These results suggest that optimal level of trace compounds might affect ruminal fermentation in ruminant.

We investigated the effect of glutathione supplementation on body weight gain, feed intake, velvet antler yield and economic analysis in elk bulls. A total 14, 2-year old male elks were divided into 2 groups with control or glutathione treatment. Elks were fed concentrate feed at the level of 1.5% relative to body weight (3.1 kg). and allowed to consumed hay as roughage ad libitum. Glutathione was supplemented at the level of 6 mg/kg. Average daily gains (ADG) for 2-years old elks were 234.1± 7 and 247.6±22 kg in control and glutathione fed groups, respectively. Treated group had higher ADG than control (p<0.05). Individual daily DM intakes were 5.34±0.70 and 5.64±0.71 kg in control and glutathione supplemented groups, respectively. Glutathione-fed group showed an additional intake of 298 g on an average. Production of velvet antlers for elk yearlings was 4,229±720 g and 4,653±960 g in control and glutathione supplemented groups respectively. Analysis of economics efficiency revealed 8% higher revenue index in glutathione supplemented groups. In conclusion, glutathione supplementation showed increase of DM intake and ADG in elk bulls, and could also increase velvet antler production.
