The data consisted of 369 lactation records for calvings over a sixteen-year period (1972-1987) and included only cows that had normal milk records. The data were analysed using a linear model containing the fixed effects of parity, year of calving and season of calving. The least squares means${\pm}$S.E. were $1,273{\pm}58.4kg$ for milk yield, and for post-partum body weight (kg) at 2, 3 and 4 months after calving were $343.40{\pm}3.96$, $346.10{\pm}4.10$ and $352.54{\pm}4.26$, respectively. With the exception of season of calving, the effects of parity and year of calving were significant (p<0.01) on the performance of the animals. Thus, the mean-milk yields 1162, 1351 and 1350, were similar for pre-, peak- and post rainy seasons, respectively. On the other hand, as parity increased from 1 to 3, milk yield also increased, but thereafter, there was a gradual decline in milk yield. Similarly, post-partum body weight also increased with parity. However, no consistent pattern for year effect was observed which probably was a reflection of the variation in climatic conditions, or forage quality and/or availability. The phenotypic correlations between milk yield and post-partum body weights were negative and small (ranging from -0.01 to -0.08). However, high milk production in cows was associated with longer calving interval. The implications from the phenotypic correlations are suggestive of one or two possibilities. Firstly, selection for increased body weight may actually result in decreased milk yield. Also, a substantial genetic antagonism may exist between milk yield and fertility in the crossbred cows. Therefore, it is important that selection to improve milk production should take into consideration the reproductive performance of the cows.

This study is conducted to evaluate the effects of containerized landscape tree production methods on post-transplant stress. Two types of container such as plastic pot(pot), fabric growing bag(bag) were adopted to restrict tree roots. Each types of containers was divided into seven sub-types. One traditional production method was included as comparison. Two landscape woody plants species (Magnolia denudata, Albizzia julibrissin) were implanted in the 7 sub-types of container. After one or two growing season in the container, each types of container trees was transplanted. Half of the trees were transplanted in the mild spring season, and another half of trees were transplanted in the improper summer season. The data were collected on the crown wilting ratio and trunk die-back ratio. The result of the analysis based on these data were as follows; 1) The container production methods were lower than the traditional production methods by 3 times in the average wilting ratio of summer season's transplanting point. 2) Post-transplant stress was more successfully mitigated, in case the "pot" type as was the "bag" types of container. 3) The effective and economic way of mitigating post-transplant stress by container production methods was selecting container plants of vigorous and deep root systems. 4) The "pot" type of container was to restrict tree roots more successfully, But, winter chilling and low temperature attacked the "pot" type tree's twigs and suckers. These results indicated that "pot" grown container plants should managed carefully during the winter after transplanting. Based upon the results of this study, a subsequent research on the development of container material, growth type of the container trees, and other maintaining method will be required.es, and other maintaining method will be required.

New post plasma nitriding can achieve a high uniformity that have been difficult in DC nitriding and have a high productivity comparable to gas nitriding. However, it has not a enough high nitriding potential for a rapid nitriding, because surface activation or ion etching in the general plasma nitriding cannot be expected. Thus, in this study, the effects of pre-treatments with oxidation and reduction gas have been investigated to improve the nitriding kinetics of post plasma nitriding. An effective pre-treatment consisting of oxidation and reduction resulted in the increase of surface energy of STD 11. This induced the surface hardness and the effective nitriding depth of STD 11. It is thought that the increase of the surface energy and the surface area with pre-treatment promote the nucleation of nitriding layer.

The Film-making industry in Korea has significantly expanded during last decade. However, the development didn't necessarily mean there's improvement in terms of the quality of life for the film staffs. In post-production stages, especially, any workers involved in the production can get tremendous amount of mental pressure and stress due to the deadline. Thus, in this period, most labor issues are found and often ignored. In this research, compared to Hollywood, Korean domestic film industry will be analyzed with focus on labor organizations. Their role will be explored and examined in terms of improving the qualify of life as well as of the film itself.

The molecular weight of proteins and protein hydrolysis products (PHP) in the fractionated post-production marinating brines left after herring marination process was determined by the HPLC. The proteins and PHP retention was evaluated in the three-stage purification process with the usage of polypropylene bag ($25{\mu}m$) and ceramic membranes with the cut-off of 150 and 1 kDa. It was found that the process of marination contributes to high participation of compounds in the post-production marinating brines. Those are characterised by low molecular weight, formed as a result of protein hydrolysis. Each stage of the scavenging process was reducing the content of proteins and PHP. The lowest retention was observed in the stage at which a PP bag was used, while the highest in the UF process, with the usage of 150 kDa membrane. The total retention of proteins and PHP differed according to the type of post-production marinating brines and reached the level of 16-22%.

과거 값비싼 워크스테이션에서만 구현 가능했던 실시간 가상스튜디오를 이제는 하드웨어의 발달로 개인용 컴퓨터에서도 운용할 수 있게 되었다. 그럼에도 불구하고 여전히 실시간 제작의 그래픽 품질에는 한계가 있기 때문에 영화나 드라마에서는 후반 제작(post production)으로 그래픽을 합성하는 것이 일반적이다. 그러나 후반 제작을 위한 순수 영상 기반 카메라 추적은 많은 작업 시간을 요하며, 자주 불안정한 결과를 보인다. 이를 극복하기 위해 가상스튜디오와 마찬가지로 촬영 단계에서 카메라 모션 데이터를 센서로부터 수신하되, 이를 저장하여 후반제작에서 활용할 수 있는 시스템(POVIS: post virtual imaging system)을 제안하였다. 실사와 그래픽의 매끄러운 정합을 위해서는 정확한 카메라 캘리브레이션이 선행되어야 하는데, 이를 위해 두 장의 평면 패턴만을 이용하여 간단하게 수행할 수 있는 캘리브레이션 방법을 사용하였다. 또한 카메라 센서 데이터는 기계적 부정합 등으로 인해 약간의 오류를 포함하게 되는데, Kalman 필터를 이용하여 이를 줄이는 방법을 제안하였다. 개발된 POVIS는 다큐멘터리 제작에 사용되어 작업 시간을 크게 단축시키고, 특징점의 부재로 인해 기존의 방법을 적용할 수 없는 영상에서의 카메라 추적을 성공적으로 수행하였다.
