Engineering phase of dairy housing systems has close connection with the milk produc- tivity of dairy cattle, the quality of milk, extension of dairy production systems, labor- saving in management of dairy cattle and the like. Moreover, the rate of investment of dairy housing facilities is of relatively high level, However, there has been almost no research effort for the improvement of engineering aspects of dairy housing systems in Korea. The purpose of this study is to find out general engineering problems and to recomm- end the improvement in dairy housing systems in Korea. Field survey by means of questionaire, direct measurements, taking pictures and sketching was conducted to get necessary information for the study. Kyung-ki Do region was firstly chosen for sampling area since it has included more than half of the number of dairy farms of the whole country. The results obtained are summarized as follows: 1. In overall dairy farm layout, the dwellings of workers were ignored in the light of sanitary environment 2. The layout of stalls in a dairy barn belongs mostly to the type of double-row face-out, which is compatible with the emphasis of manure disposal activities. 3. While the width and length of stalls were sufficiently close to the standard dimension, the width of mangers was much less than the standard dimension. 4. The width and depth of manure gutters and the width of working alleys were much. less than the standard dimension. 5. The mooring equipment was mostly in the classes of chain or rope. The watering equipment was not facilitated independantly except the one cese of using watercup. 6. The bucket milkers with one or two bucket milkers with the capacity of two cattles. each were used as milking equipment in most dairy farms. 7. There were only few milk rooms independently spaced from other space, in which the arrangement of milking equipment was much less than the standard condition. 8. The lounging ground area was averaged to be sufficient for the activity of dairy herd. 9. Silos for silage used during winter consisted of mostly bunker silos, trench silos and underground vertical silos. Ordinary vertical silos were considered for the farmers to be inconvenient for the labor saving. 10. From the view point of heat conservation and moisture removal within the dairy barns, windows were not flexible for the easy ventilation and ceiling part was not adequate for temperatur maintenance. 11. Waste treatment and disposal systems were not provided with most dairy farms, therefore the livestock waste pollution problems would be serious in the near future.

This paper describes Monte Carlo Simulation(MCS) to assess the uncertainty of dynamic pressure calibrator and the expanded uncertainty results that were compared by GUM approximation and MCS. MCS uncertainties were computed using defining a domain of possible inputs, generating inputs randomly using probability distribution, performing a deterministic computation repeatedly and aggregating the results. It was revealed that the expanded uncertainty between GUM and MCS was different from each other. the expanded uncertainties were 0.5366%, 0.4856%, respectively. MCS is a suitable method for determining the uncertainty of simple and complex measurement systems. It should be more widely used and studied in measurement uncertainty calculations.

The purpose of this study was to analyze the magnitude and mode of the stress distribution induced in the supporting alveolar bone and periodontal ligament and, to determine the displacement of abutment teeth and telescope denture base by applying chewing force to the telescope denture quantitatively and qualitatively. Two finite element models of telescope denture that were restored the missing mandibular second molar with two abutment teeth which were constructed. In two different models, parallel and tapering type telescope crowns were constructed. These finite element models of two cases used for these experiment were a two-dimensional mesiodistal section of the mandibular second bicuspid and first molar. Chewing force of 25Kg that was devided in the ratio of 45/155 (29%) in bicuspid and 55/155 (35.5%) in molars was applied to telescope denture and abutment teeth respectively. The displacement of the telescope denture base and abutment teeth and the stress distribution in the periodontal ligament and alveolar bone were analized to investigate the influence of chewing force acting on the telescope denture and abutment teeth. The results were as follows: 1. Abutment teeth displaced mesially and the magnitude of displacement of abutment teeth in vertical direction were more than that of horizontal direction in two cases. The displacement of abutment teeth on the telescope denture treated with tapering type telescope crown were less than that of the parallel type crown. 2. The displacement of the telescope denture base that were treated with parallel type telescope crown were less than that of treated with tapering type telescope crown. 3. The stress induced in the alveolar bone and periodontal ligament on abutment teeth that treated with parallel type telescope crown were more than that of treated with tapering type telescope crown and more stress induced in the alveolar bone than in the periodontal ligament. 4. In the telescope denture, the magnitude of displacement of abutment teeth and stress induced in the periodontal ligament and alveolar bone were within physiologic limit.

공기 팽창식 이중 플라스틱 온실이 집약 농업 생산에 있어서 그 이용도가 증가되고 있다. 낮은 압력 (0.25인치 H₂O)의 공기를 이용하여 이중 플라스틱 막층을 분리시키는 개념은 플라스틱 덮개를 고착시키는데 효과적인 방법을 가능케 하였다. 어떤 형태로던 온실에 있어서 구조체의 부재의 양을 줄인다든가 간소화 하는것은 온실내부에 그늘진 부분의 면적이 줄어든다는 것과 구조물의 초기 비용을 덜어준다는 점에서 이중의 효과를 얻게 된다. 최근에 개발된 시험적인 케이블 지지, 공기 팽창식 플라스틱 덮개와 여러가지 구조 요소의 하중, 응력, 변형 등의 해석을 다루었다. 첫째, 지붕을 이루고 있는 플라스틱 덮개의 처짐량을 계산하는 공식을 개발하였다. 지붕단면의 모양을 긴 원통의 단면으로 가정함으로써 단면의 기하학과 플라스틱 막응력을 추정할 수 있게 하였다. 둘째, 팽창된 이중 플라스틱막을 온실 내부에서 지지하기 위하여 사용된 케이블의 초기 인장과 팽창압력에 따른 최종 인장력 및 변형 처질을 해석하여 근사 관계식을 개발하였다. 셋째, 케이블 대용으로 개발된 3/4인치 강파이프의 사용이 제시되었고 따라서 하중과 양단 조건에 따른 응력 및 변형 처짐을 계산하여 설계에 사용할 수 있는 공식들을 제공하였다. 넷째, 풍하중이 온실 시스템 전체에 미치는 영향을 재래적인 방법에 의하여 추정하였고 그 결과가 실제적으로 경험할 수 있는 결과와는 상당한 차이가 있음을 지적하였다. 플라스틱 온실 설계에 있어서 관건이 되고 있는 플라스틱 덮개, 지지 케이블 및 지지 강파이프등의 실제 하중 조건 및에서의 변형의 일부를 측정함으로써 개발된 추정공식들이 설계 목적상 이용이 가능함을 보여주고 있다.

Schizophrenia and the Sublime

Moon Ki Kim(김문기) 한국셰익스피어학회 2000 셰익스피어 비평 Vol.36 No.3

포스트모더니즘 논쟁에서 야기된 언표성(Referentiality)의 괴리 현상은 정신분열증(schizophrenia)이나 숭고미(the sublime)를 포스트모던 시대의 대표적인 사회적ㆍ 예술적 현상으로 부각시켰다. 로버트 윌슨은 그의 독특한 형식주의적 연출법으로써 바로 이러한 포스트모더니즘의 내면적 풍경을 관객으로 하여금 연극무대에서 경험하게 했다. 이 논문은 로버트 윌슨이 연출한 『리어왕』(King Lear)을 대상으로 그의 형식주의적 연출법이 어떻게 셰익스피어의 텍스트와 대면하여 포스트모던이즘의 정서적ㆍ사회적 풍경을 효과적으로 그리고 있는지를 살펴 보았다. 로버트 윌슨은 『리어왕』에서, 일반적인 셰익스피어 공연의 역사나 관행들을 무시하고, 왕권과 도덕성에 대한 논의마저도 배제하고 다만 추상적이고도 기하학적인 낯선 공간(no man’s land)올 무대 위에 펼쳐 보였다. 그 공간에서 인간의 폭력성, 우주적 혼돈, 죽음, 실성과 같은 아주 격렬하고도 충격적인 리어왕의 주제들을 일련의 장면들로 전개하면서 환상적인 무대의 조명과 시각적 이미지, 수직선과 수평선의 교차로 이루어진 독특한 건축학적 무대구성, 정형화되고 추상화된 느린 신체 동작, 언어와 행위의 의도적 비틂 등 차갑고도 아름다우며 정제된 로버트 윌슨 특유의 형식으로 표현하였다. 로버트 윌슨은 셰익스피어의 텍스트 뿐만이 아니라 대사 동작, 음향효과 등 다양한 각각의 연극요소들로 하여금 하나의 독립적인 단위로서 서로 경쟁하고 대치하게 하였다. 이러한 무대위에서의 텍스트와 표현양식, 한 표현양식과 다른 표현양식의 충돌은 관객들에게 예상치 못했던 심미적ㆍ정서적 경험을 제공하였다.

So far today, there is a speed limit by the radius of curve based on operation regulation in domestic railway, however a study for the maximum running speed at the curved section without any derailment would be necessary. The two major factors related to the running safety of railway vehicle are classified as the railway vehicle condition and the track condition. In terms of the rail inclination among many other factors, the determination of rail inclination within the possible limit is necessary for the geometrical structure of the optimum track. The disregard of the geometrical parameter related to the rail inclination may cause a serious problem to the running safety of railway vehicle. This study is focusing on the analyzing of running safety regard to the change of rail inclination among the many other parameters to improve derailment safety, so that there is an affection analysis of the running safety regard to the change of rail inclination in the ideal and geometric track condition. Also There is an affection analysis of the running safety regard to the simultaneous change of rail inclination and the running speed at the curved section. According to analysis results of running safety, In case that the left and right rail inclination are 1/40, the running safety of this condition defined than other conditions. Also, the rail inclination of conventional lines is 1/40, Therefore, the railway vehicle passing through curve is safe when the railway vehicle runs in conventional lines.
