  • Background: Despite the importance of relationships between somatic cell score (SCS) and currently selected traits (milk, fat and protein yield) of Holstein cows, there was a lack of comprehensive literature for it in Iran. Therefore we tried to examine heritabilities and relationships between these traits using a fixed-regression animal model and Bayesian inference. The data set consisted of 1,078,966 test-day observations from 146,765 primiparous daughters of 1930 sires, with calvings from 2002 to 2013. Results: Marginal posterior means of heritability estimates for SCS ($0.03{\pm}0.002$) were distinctly lower than those for milk ($0.204{\pm}0.006$), fat ($0.096{\pm}0.004$) and protein ($0.147{\pm}0.005$) yields. In the case of phenotypic correlations, the relationships between production and SCS were near zero at the beginning of lactation but become increasingly negative as days in milk increased. Although all environmental correlations between production and SCS were negative ($-0.177{\pm}0.007$, $-0.165{\pm}0.008$ and $-0.152{\pm}0.007$ between SCS and milk, fat, and protein yield, respectively), slightly antagonistic genetic correlations were found; with posterior mean of relationships ranging from $0.01{\pm}0.039$ to $0.11{\pm}0.036$. This genetic opposition was distinctly higher for protein than for fat. Conclusion: Although small, the positive genetic correlations suggest some genetic antagonism between desired increased milk production and reduced SCS (i.e., single-trait selection for increased milk production will also increase SCS).

  • Nowadays LNG has been beginning to take the place of petroleum as fuel all over the world and VLCC of LNG will take the same sea routes that had been used by VLCC tankers of petroleum in the last part of the 20th century. The transportation of LNG by a VLCC include more dangerous nature of sea peril than that of petroleum. We already know the dimensions of a disaster a LNG tanker could bring about in the case of the LNG tanker, Yuyo-Maru No. 10 in the Tokyo Bay of Japan in 1974. From the point of safety when we construct a LNG base or LNG pier in the base, the appropriate government authority and constructing company had better take sea pilots or some ships handling experts to participate in a prior consultation of the design of the project. A G/T 100,000 ton LNG base and pier were completed in November of 1996 in Inchon harbour in Korea and VLCC of LNG of G/T 100,000 ton class have been entering into the base ever since. This study was started and completed In comply with the requisition of the Sea Pilot Association of Inchon harbour in advance of the opening of the LNG base. As the entrance and exit channels leading to Inchon harbour were constructed in the years of 1930s, it was one of the most pressing works for Inchon sea pilots in 1996 to certify the method of safe passing maneuvering of a G/T 100,000 ton of LNG tanker through the Pudo narrow channel prior to commencing actual piloting of the VLCC of LNG. The authors made some mathematical models computing maneuvering of a vessel changing her course with her control surface through a narrow channel and computed maneuvering of a G/T 100,000 ton of LNG tanker and also made maneuvering simulations of the vessel by a desk-top simulator. The results of computations and simulations are well coincided with each other in qualitative aspects to assure safe passing of the VLCC of LNG.

  • Ikseon-Dong 166 is one of the traditional urban resident area developed during 1930's. The purpose of this research is to analyze the structural relationship between a conventional housing unit plans and modern block plans based on orthogonal geometry. To fully explore the selling point of the new urban development, the planner or real estate developer in private sector did not abandon or compromise the conventional house layouts, consists of single layer of rooms keeping the main room facing south. This study concludes the following factors connecting the urban and architectural plans. Oblong block plans following east-west direction did not allow the southern exposure of courtyard and main room, which was the absolute requirement for traditional house units, the longer side of block plan followed north-south direction as a result. Considering the possibility of rent, having entrance at the east or west side of individual site enables two separate household maintain their spatial privacy. In addition to the factors mentioned above, when the blocks are to be divided into individual addresses, north-south oblong block plans maintained the length to face the front road minimum while the southern exposure maximized. These factors explains why the private developers maintained their blocks elongated to north-south direction when the block plans laied out by public sectors which did not care that much of southern exposure show random orientation in the view point of solar exposure.

  • 폴 푸아레 (1879-1944)가 패션 역사상 혁명적이라고 할 수 있는 여성의 코르셋을 제거시켰다는 것은 익히 알려진 사실이다. 그리고 그러한 결과로 인해 발생된 새로운 직선형의 실루엣에 화려한 색채와 장식을 하여 이전 시대와는 전혀 다른 현대패션의 근원이 되었다. 본 연구는 푸아레의 새로운 직선 실루엣과 화려한 색채와 경이적 장식의 근원이 다름아닌 동양이라는데 중점을 두었다. 이미 국내의 몇편의 논문에서 이러한 논의가 지적되어 왔으나 다른 논제를 다루는 중에 언급이 되었고 당시의 작품이나 동시대의 자료를 분석한 것이 아닌 근래의 출판물에 의존한 연구가 대부분이었다. 따라서 본 연구에서는 그의 동양풍 디자인의 근원을 밝히는데 있어 가능한한 1 차적 자료의 접근을 시도하였다. 1912년 작품인 이브닝 드레스, 터번, 숄, 구두 각 1점과 그의 작품 의도와 생애의 추구를 말해주는 자서전(1930년 불어본 및 1931년 영어본)과 보그(Vogue)지의 기사(1920년 2월호, 9월호) 등을 통하여 그의 동양에 대한 관심을 살펴보았다. 그 결과 푸아레의 동양 영향의 근원은 19세기 말 유럽에서 절정을 이룬 'Sino-Japonism'(중국-일본주의)의 심취, 러시아 발레단의 의상과 색채, 천일야화의 영향에 의한 중동(페르시아)에 대한 열망, 그리고 인도 토민병의 복식에서 비롯된 터번에의 매료 등이었음을 알 수 있었다. 이러한 근원에서 탄생된 디자인으로는 직선형의 튜닉, 기모노 소매(처음엔 푸아레 자신도 중국의 것으로 혼동을 하기도 했지만), 하렘팬츠, 비대칭적인 카프탄식의 코트, 원색의 사용, 극동지역의 직물과 문양, 술장식, 터번 등으로 나타내었다. 따라서 폴 푸아레의 동양적인 관심은 단지 개인적 '취향 혹은 취미(taste)'가 아니라 한 시대양식으로 자리잡은 '동양주의(Orientalism)'라 할 수 있으며 이러한 푸아레의 동양주의는 당시의 패션에 있어 신체의 선을 부정하여 코르셋을 제거 시키게한 그의 모더니즘의 근거가 된다. 본연구의 제한점으로 1차적 자료를 수집하는데에 있어 보다 폭넓지 못했던 점을 밝혀둔다.

  • Since the late 1930s, acrylic resins have been the materials of choice for the fabrication of complete denture bases. It has excellent esthetic properties, adequate strength, low water sorption, and low solubility. But acrylic resin has disadvantage of processing shrinkage that reduces denture retention and accuracy of denture occlusion. Metals also have been used in denture base material. Metals used in denture bases display excellent strength and dimensional stability. The major disadvantages associated with metal denture bases include increased cost, difficulty in fabrication, compromised esthetic qualities, and inability to re-base. The purpose of this study is to compare the artificial tooth movements of complete dentures with resin bases and metal bases after curing, deflasking, polishing immersion in water for 1 week and 4 weeks. Twenty-four maxillary complete resin denture bases with artificial teeth were fabricated. Twelve of them were resin based and other twelve of them were metal based. Fine crosses were marked on the incisal edges of right central incisors and distobuccal cusps of be second molars. Measurements were done for the changes of distances of reference points at the time of wax denture, after deflasking after decasting after polishing after immersion in water for 1 week and 4 weeks Meaurements were done to the accuracy of 0.001mm with a measuring microscope. The results were as follows : 1. Metal base showed significantly less tooth movement than resin base after curing and decasting (p<0.01). 2. Metal base showed significantly less tooth movement than resin base after polishing (p<0.01). 3. After immersion in water for 1 week and 4 weeks, metal base showed less movement than resin base. Difference was significant for anterior-posterior distances (p<0.01), but not significant for molar-to-molar distance (p>0.01). 4. 1 week and 4 weeks of immersion failed to compensate the initial processing shrinkage of metal and resin bases (p>0.01).

  • Objectives : Although the controversy surrounding the biomechanics of the sacroiliac joint remains unresolved at this time, the clinical importance of this joint in the cause of back pain has been established since 1930's. Recently, there has been renewed interest in the sacroiliac joint. This study was performed to evaluate the effects of pulsed electromagnetic therapy(PEMT) with acupuncture therapy for patients, who were suffering from sacroiliac joint syndrome, and to conduct more researches in the usage of acupuncture therapy for treating sacroiliac joint syndrome. Methods : 25 patients, who were diagnosed as sacroiliac joint syndrome were selected. They were treated twice a week during 3 weeks. They were measured after all the treatment and firs week and fourth week after termination of treatment by using visual analogue scale(VAS) and Roland Morris disability index(RMDI). The VAS and RMDI patterns were analyzed by using 'pared T-test' and 'Kruskal-Wallis' test. Results : 1. Each times of PEMT with acupuncture therapy, there were statistical significance in improvement of VAS(p<0.05) and each times of therapy except 1st one, there were statistical significance in improvement of RMDI(p<0.05). 2. After 4th therapy, there were most significant improvement of VAS with RMDI(p<0.001), when we compared the change in VAS and RMDI before and after the each therapy. 3. There was no statistical significance in VAS and RMDI by onset, sex and age. Conclusions : The results indicate that pulsed electromagnetic therapy and acupuncture therapy had good effect on sacroiliac joint syndrome.

  • This paper has analyzed the relation of conduction path and subthreshold swing for doping profile in channel of asymmetric double gate(DG) MOSFET. Since the channel size of asymmetric DGMOSFET is greatly small and number of impurity is few, the high doping channel is analyzed. The analytical potential distribution is derived from Possion's equation, and Gaussian distribution function is used as doping profile. The conduction path and subthreshold swing are derived from this analytical potential distribution, and those are investigated for variables of doping profile, projected range and standard projected deviation, according to the change of channel length and thickness. As a result, subthreshold swing is reduced when conduction path is approaching to top gate, and that is increased with a decrease of channel length and a increase of channel thickness due to short channel effects.

  • This article provides the base in relation to the classification system of public records of Japan and Tiwan which the original order of the classification system of public records of Government-General of Chosun is reconstructed and the efficient classification system is prepared. The classification system of public records at the period of Meiji(明治) in Japan was classified two forms, one is function-based classification, the other is organization-based classification. Each ministry(省) was fundamentally based In function-based classification and organization-based classification, adopted them in changed forms as its condition and situation had been changed. Government-General of Tiwan adopted Japan's archival management system and put its classification system and life schedule In operation. The classification system of Government-General of Tiwan adopted function-based classification of the ministry of foreign affairs in Japan, changed its forms as the organization and business activity were transformed. As a result of arrangement and analysis of examples for the classification of public records of Government-General of Chosun from 1910' to the middle area of 1930', the classification of public records of Government-General of Chosun was constructed on level order; 'organization of ministry(部) or department(局)--business activity of ministry or department--low function of business activity of ministry or department'. But this classification system had two sides, flexible and unstable in that the classification system had exeptional parts and the breadth of items was changed greatly. The classification system of Government-General of Chosun, which had adopted organization-based classification of the ministry of home affairs in Japan, result in expanding the breadth of items and causing great change of items for the organization and business activity were vast and its change was very great.
