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.

유한요소법(有限要素法)에 의(依)한 Telescope Denture의 지대치(支臺齒) 및 지지조직(支持組織)의 역학적(力學的) 반응(反應)에 관(關)한 연구(硏究)
김문기,최부병,Kim, Moon-Ki,Choi, Boo-Byung 대한치과보철학회 1984 대한치과보철학회지 Vol.22 No.1
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.

케이블로 지지(支持)하는 공기팽창식(空氣膨脹式) 플라스틱 온실(溫室)의 구조상(構造上)의 분석(分析)
김문기 ( Moon Ki Kim ) 한국농공학회 1972 韓國農工學會誌 : 전원과 자원 Vol.14 No.4
공기 팽창식 이중 플라스틱 온실이 집약 농업 생산에 있어서 그 이용도가 증가되고 있다. 낮은 압력 (0.25인치 H<sub>2</sub>O)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.

김문기(Moon Ki Kim),최정수(Jung Su Choi),김삼주(Sam Ju Kim),김현구(Hyun Gu Kim) 大韓環境工學會 2013 대한환경공학회지 Vol.35 No.7
본 연구의 목적은 도심지역 중소하천의 효율적인 수질정화를 위해 물리화학적, 생물학적 처리공정을 결합한 장치형하천수질정화공법의 적용성을 평가하는데 있다. 본 연구의 하천정화시설은 TSS 및 TP 제거를 위한 가압부상(Micro Bubble Process, MBP)공정과, BOD 제거를 위한 관로형 미생물 부착(Attached Microbial Pipe System, AMPS)공정으로 구성하였다. 각장치의 실험 조건은 MBP 공정의 부상조 체류시간 및 초미세기포 주입량 변화와 AMPS 공정의 체류시간의 변화를 설정하였다. 또한 계절 변화에 따른 각 공정의 오염원 제거효율을 평가하였다. 각 공정의 연속운전 결과 MBP 공정에서는 최대 TSS 83.69%, TP 95.15%의 처리효율을 나타냈으며, AMPS 공정의 TBOD5 제거효율은 최대 53.0%를 나타냈다. 또한 각 공정의 순환운전 결과 MBP 공정에 의해 최대 TSS 69.75%, TP 70.17%의 처리효율을 나타냈으며, AMPS 공정에 의해 TBOD5 제거효율은 최대 68.58%를 나타냈다. 따라서 본 하천정화시설은 도심지역 내 오염된 하천의 수질을 개선하는데 효과적이라고 사료된다. The purpose of this study is to assess the applicability of device-type stream coagulation process which combines physiochemical, biological processing for efficient improvement of water quality in small, middle-sized urban streams. The stream purification facility of this study is compose of pressure flotation type Micro Bubble Process(MBP) to remove TSS and TP and conduit line type Attached Microbial Pipe System(AMPS) to remove BOD. Test conditions of each device were set by floating stay time and change of ultra fine bubble injection amount of MBP, and change of AMPS stay time. Also, removal efficiency of pollution sources of each process were assess by change of season. As result of continuous operation of each process, MBP showed a maximum of TSS 83.69%, TP 95.15% process efficiency and AMPS showed a maximum of 52.95% TBOD5 removal efficiency. Also as result of circular operation of each process, MBP showed a maximum of TSS 69.75%, TP 70.17% process efficiency and AMPS showed a maximum of 68.58% TBOD5 removal efficiency. Therefore, it is considered that this stream coagulation process is effective in improving the water quality of streams in urban areas.
