The effects of dietary fiber on true digestibility of amino acids by growing pigs were studied, using semi-purified diets formulated from alfalfa meal, cassava leaf meal, rubber seed meal and leucacna meal at 20% level. A protein-free diet including 5% cellulose was formulated for correcting the endogenous amino acid loss. Across all the diets, arginine was the most digestible while the least at ileal level was threonine; methionine and/or histidine at fecal level respectively. The true digestibility value of amino acids at ileal level were higher than at fecal level except control diet (cellulose). The true digestibility values at ileal level were similar for all diets but differed at fecal level in different magnitude. These results indicate that undigestible compound in individual feedstuff might confound. True digestibility should be studied together for accurate diet formulation as apparent digestibility decreased when their amino acid concentration in the diet was reduced.

This paper for the method that automatically extracts moving object of the video image is presented. In order to extract moving object, it is that velocity vectors correspond to each frame of the video image. Using the estimated velocity vector, the position of the object are determined. the value of the coordination of the object is initialized to the seed, and in the image plane, the moving object is automatically segmented by the region growing method and tracked by the range of intensity and information about Position. As the result of an application in sequential images, it is available to extract a moving object.

영상 분할은 임상에서의 진단과 분석 및 3차원 가시화하는데 있어 선행되어야 할 필수적인 과정이다. 본 논문에서는 심혈관계 영상의 분할을 위한 Wave-front SRG방법을 제안한다. 제안된 방법은 2차원 슬라이스 영상에서 사용자에 의한 씨앗점(seed front)을 입력으로 받아 그 이웃한 슬라이스들에 wave-front를 만들어 영역 성장법에 의해 3차원 volume을 확장시킨다. 이때 다음으로 성장할 wave-front voxel의 mean gradient 값을 사용하여 밝기값의 변화가 심한 심혈관계 영상을 분할하였으며, Wave-front voxel의 size를 계산하여 혈관분할 시 발생할 수 있는 작은 채널에서의 새나감을 방지하였다. 제안된 방법을 컴퓨터 단층촬영으로 얻은 심혈 관계 영상의 분할에 적용한 결과, 밝기값의 변화가 심한 심혈관계 영상을 성공적으로 분할했으며, 작의 채널의 새나감이 없이 분할을 수행하였다.

The interest of oligomeric proanthocyanidins(OPCs) as therapeutic agents against diseases involving radical damage is growing. Proanthocyanidins are a class of polyphenolic compounds in several plant species and are oligomers of flavan-3-ol monomer units. Polyphenols in green and black tea, grape seeds, grapes and wine have raised much attention but mountain grape seed has not been investigated intensively up to now This study investigated the total OPCs contents and the total antioxidant activity of mountain grape seeds. Total antioxidant activity using DPPH method was employed and OPCs contents were determined by means of the UV-VIS spectrophotometer. The total OPCs yield of mountain grape seeds was about 1.45 % and total antioxidant activity was 15.8 ${\mu}g/m{\ell}$.

Bambusa arundinacea family Graminae, is one of the precious plant resources of the earth. It has played a significant role in human civilization since ancient times. It is tall sized tree growing throughout India, moist parts of India. It also occurs in Sri Lanka, Malaya, Peru and Myanmar. The different parts of this plant contain silica, cholin, betain, cynogenetic glycosides, albuminoids, oxalic acid, reducing sugar, resins, waxes, benzoic acid, arginine, cysteine, histidine, niacin, riboflavin, thiamine, protein, gluteline, contains lysine, methionine, betain, cholin, proteolytic enzyme, nuclease, urease. Various parts of this plant such as leaf, root, shoot and seed possess anti-inflammatory, antiulcer, anti-diabetic, anti-oxidant, anthelmintic, antifertility, antibacterial, insectisidal, antiarthritic, vessele protection etc. This review mainly focuses on the traditional, phytochemical and pharmacological information of Bambusa arundinacea.

This experiment was conducted to evaluate the effect on evapotranspiration and yield of soybean according to different soil water conditions, and to find the optimum time and amount for irrigation in soybean cultivation. The difference between potential evapotranspiration (PET) and maximum evapotranspiration (MET) during growing season of soybean planted in lysimeter was higher during reproductive stage than during vegetative one. The maximum crop coefficient was obtained at beginning seed stage of soybean. Soil water coefficient of irrigation treatment was higher than that of non-irrigation treatment during soybean growth stage in field experiment. Grain yield was highest in lysimeter due to its high water use efficiency and evapotranspiration rate.

Defect region segmentation of TFT-LCD images is performed by combining defect pixels detected by a defect detection method into defect region, or by using morphological operations to segment defect region. Therefore, the result of segmentation of the defect region is highly dependent on the defect detection result. In this paper, we propose a method which segments defect regions sequentially according to the possibility of being included in defect regions in TFT-LCD images. The proposed method repeats the process of detecting a seed using the median value and the median absolute deviation of the image, and segments the defect region using the seeded region growing method. We confirmed the superiority of the proposed method to segment defect regions using pseudo-images and real TFT-LCD images.

To cultivate Dystaenia takesimana as a fodder crop, Its problems and solutions are summarized follows : 1. There are a wax layer and wings on the out side of seed coat of D. takesimana seeds, which seems to inhibit imbibition and cause delayed germination. 2. The root and shoot growth of D. takesimana are very poor in the early stage and weed control is quite troublesome. 3 The growth of D. takesimana is very poor the soil of low fertility and much depressed in summer. 4 . The percent germination could be increased by removing wings, soaking, high temperature treatment or by chemical scarification. 5. Compost is most effective for the growth of D. takesimana and lime dressing is desired in the soil of low pH. 6 . The seedling growth could be improved selecting and breeding the strains with better germination and root growth, at the germination and growth characteristics of D. takesimana are variable.

A grafting method, cleft grafting of ordinary dormant scion into an inverted radicle of a germinated seed was tested with good success for chestnut as well as for walnut trees. It was seen that verticilate roots which were produced from the cut and of radicle after grafting made a complete union with scion and made healthy development to produce a successful graft. The radicle before secondary rootlets emerged from its rooting zone was proved to be best stock for inverted radicle grafting. The dormant but was also used for grafting scion with success in this method. Though green house grafting gives higher survival, field grafting was also feasible by this method. Those early growing geason after grafting, the later development of root system and the shoot of the graft were to be studied in the future.

Bowlesia incana Ruiz & Pav., a new invasive alien plant in Korea, was found in Ulju-gun, Ulsan Metropolitan City. This species is characterized as being similar to the genera Hydrocotyle Tourn. ex L. and Centella L. However, it differs morphologically from these two genera in leaves, flowers, and fruits, as well as stellate pubescence growing on the whole plant. In Korea, Bowlesia incana Ruiz & Pav. is recorded for the first time in this study. A morphological description, distribution map, and illustrations based on the Korean materials collected are presented.
