Video scene segmentation is fundamental role for content based video analysis. In this paper, we propose a new region based video scene segmentation method using continuity test for each object region which is segmented by the watershed algorithm for all frames in video data. For this purpose, we first classify video data segments into classes that are the dynamic and static sections according to the object movement rate by comparing the spatial and shape similarity of each region. And then, try to segment each sections by grouping each sections by comparing the neighbor section sections by comparing the neighbor section similarity. Because, this method uses the region which represented on object as a similarity measure, it can segment video scenes efficiently without undesirable fault alarms by illumination and partial changes.

Wound healing is a complex and highly organized biological response to injury that results in the loss of tissue integrity. Our particular interest was propolis, traditional used as an antimicrobial and an anti-inflammatory agent. The purpose of this study was to see the effects of propolis on healing of the laser induced wounds and the level of collagen formation. 808 nm laser (20 J) was irradiated on the back of rats. Irradiated wounds were divided into gel control and 6 experimental groups (3 and 5% of different three kinds of propolis). Gel type of propolis (supplied by Seoul Propolis Co., Daejeon, Korea) in water based were applied on the laser wound once daily for 14 days. One fourth of rats were sacrificed on $3^{rd}$, $7^{th}$, $10^{th}$, and $14^{th}$ day and each wound was evaluated for degree of wound healing and the level of collagen formation. Healing of wound was evaluated by measuring and comparing the width and depth of the wounds. The levels of collagen were increased in 3 and 5% gel groups comparing to control on $3^{rd}$ day and the collagen level were increased more on $7^{th}$ day. Wounds of the experimental groups showed better healing in width comparing to the healing of the control. The results of this study demonstrated that propolis accelerated healing of wounds induced by laser irradiation and good collagen formation.

In the plaque formation test, the control and test group were not shown significant differences. 6. In the foot pad swelling respopnse, the control group was decreased on DTH response but test group was increased comparing to the normal group. 7. There was no change on the distribution of lymphocyte subset(CD4, CD8), grnulocyte and macrophage analyzed by flow cytometry.

The definite objects of this study are as follows; 1. The study presents the methods of the designing collar pattern and bodice pattern by each concrete object after comparing and analyzing the factors among the features which are in need of clothes designing. 2. The object of this study is to make body-suitable ready-made clothes by comparing and analyzing the methods of designing collar pattern and bodices pattern presented by each concrete objects and Bunka Pattern. The results of this study are as follows; 1 . The results of this study developed the body-suitable bodice pattern of bend-forward type, straight type and lean-back type Compared with the Bunka pattern by physical function test, this study was rated high in the aspects of the shape of neck and shoulder. 2. The collar pattern was designed according to each type. The front center rising point of straight type is 2.5cm, lean-back type is 3.0cm and bend-forward type is 1.5cm. Compared with the Bunka pattern by physical function test, this study is rated high in the aspects of the shape. To confirm the increase and change of the measure definitely, the complete examination of each subject is necessary. This developed and investigated pattern must be supplemented more by comparing and analyzing with other pattern and body types.

The objective of this study was to investigate the effects of $\alpha$-tocopherol and selenium on the boar semen characteristics. Semen volume and pH values were not different among treatments. However sperm concerntration, total number of sperm and sperm mortility were significantly(P＜0.05) increased comparing to the control group and sperm abnormality was significantly(P＜0.05) decreased comparing to the control group. Also, sperm mortility by storage day was significantly(P＜0.05) increased comparing to the control group. The results from this experiment indicate that dietary $\alpha$-tocopherol and selenium can affect boar semen characteristics.

A device far estimating the optimal artificial insemination time consisted of a computer, RS module, and six direct-reflex photo-sensors. Program was written in LabWindows CVI. In order to establish references for estimating optimal artificial insemination time, lying rate of the thirty three $Berkshire{\times}Hampshire crossbred sows (parity 5 to 6) was recorded from 2 days after moving into stalls to artificial insemination using a time lapse VCR and was measured every hour with one minute interval using the scan point sampling method. Twenty low hours in a day were divided into three comparing periods : 21:00 to 06:59, 07:00 to 13:59, and 14:00 to 20:59. If sum of the percentages of tying during a comparing period was less than the reference value, the starting hour of the comparing period was considered as onset of estrus and the optimal artificial insemination time was estimated at 20 to 24 hours after onset of estrus. The experimental device was evaluated with twenty five $Berkshire{\times}Hampshire$ crossbred sows (parity 2 to 7) and 23 of 25 sows $(92\%)$ were pregnant. This result suggests that the experimental device is excellent in performance for estimating optimal artificial insemination time.

Objectives : In order to select the key factors of formulae and to identify the relationship of formulae with comparing these factors. Methods : We selected the five key factors that the source, the name of formula, the efficacy, the constituent herbs, and the capacity of herbs. When we compared between two formulae with five key factors, there was 32 cases. So we investigated the example which is corresponded to each cases and analyzed the relationship of formulae. Results : Among the 32 cases, analyzed two formulae was same in 8 cases, altered from same formula in different ways in 14 cases, and different with each other in 20 cases. Conclusions : These five key factors play a decisive role to comparing formulae and analyzing the relationship of them. So these factors and the relationship of formulae would be considerated to construct formula ontology.

To evaluate the effect of winter intensive training on pulmonary function in high school baseball players, comparisons of various ventilatory parameters were made before and 3-3.5 months of winter intensive tranining. The subjects were 18 members of a high school baseball players with mean age and career of 6.3 and 7.3 years, respectively. The following were mainly observed by spirometry for the study ; respiratory rate, vital capacity(VC), maximum voluntary ventilation(MVV), forced vital capacity (FEV1%) and forced mid-expiratory flow (FEF25-75%). The result obtained are summarized as follow. 1) Resipratory rate, tidal volume, forced vital capacity, 1FEV%, FEF50% and FEF75% showed no significant difference between before and after. 2) MVV in after was significantly(p<0.001) increased to 166 L/min comparing with 136L/min in before. 3) 1FEV in after was significantly(p<0.05) increased to 4.46L comparing with 3.76L in before. 4) PEF in after was significantly(p<0.05) increased to 10.40 L/sec comparing with 9.18 L/sec in before.

Anionic epoxy compound was synthesized and added to asphalt aiming to prepare self-healing asphalt. Epoxy-modified asphalt showed excellent modification effect and healing effect as well. The results revealed that with 5% addition of polymer the tensile strength, impact strength and complex shear modulus of the polymer-modified asphalt increased by 65%. 64% and 35%, respectively. It seems that high interaction occurs between polymer and asphalt matrix. Self-healing efficiency of the polymer-modified asphalt based on tensile strength showed 100%, comparing to 79% of straight asphalt. In impact experiment the polymer-modified asphalt showed 99% of healing efficiency, comparing to 77% of straight asphalt. In rheological experiment the polymer-modified asphalt showed 103% of healing efficiency, comparing to 72% of straight asphalt. It appears that the ionic bonding existing in epoxy polymers contributed to high values of self-healing efficiency. The polymer which has high intermolecular force fills the crack of the asphalt, pulling the opponent side each other, and so the original properties were restored.
