Shadow mask is one of the key components which decide the quality of CRT screen. Therefore, the inspection of the exactness of shadow mask forming is important. However, current contact type coordinate measuring machine can only confirm individual measured points. Analysis software for new non-contact shadow mask inspection system which can reduce inspection time and inspection errors rather than current contact type coordinate measuring machine is developed. The developed software can confirm not only individual measured points but also the whole surface profile of the measured shadow mask.

In this paper, an numerical approach is performed to investigate the effects of smear zone, occurred by penetrating vertical drains, on consolidation behavior of soft clay deposits. Such a numerical analysis is applied to the field condition to confirm its applicability. Parametric numerical analyses is carried out to study influencing factors such as permeability in smear zone, boundary of smear zone and discharge capacity of vertical drains on the consolidation of soil. As results of analyses, for the given conditions of soil, degree of consolidation is getting faster with increase of permeability of vertical drain. Degree of consolidation is delayed with decrease of permeability of smear zone. As the ratio of drain width to smear zone increases, the degree of consolidation decreases. Proposed values of influencing factors by previous researchers is found to be reliable from results of numerical analyses with Cam-clay model.

Presented in this paper is a DNC verification and editing system architecture for embroidery manufacturing. Embroidery machines are numerically controlled machines with multi head, but they have not standard RS-232C communication port in general. So embroidery machines receive NC data from reels of 1 in . wide tape containing holes. But punched tape as an input media has many defects. In this paper, we present DNC(Direct Numerical Control) verification system eliminating punched tape. With the proposed system, NC data editing algorithm are also presented.

Clinical studies were carried out 105 cases of patients with stomach cancer treated by Hangamdan(抗癌丹) from January 1th 1998 to September 30th 2000. The results were summarized as follows; 1. Distribution of those attached by stomach cancer, by sex, showed that Male is more then Female, by age, showed that the number of forties, fifties, sixties are majority. 2. Distribution of diagnostic stage, in descending order; stage Ⅲ(45.1%, top), stage Ⅳ(40.2%). 3. The effects of maintenance and improvement in the symptoms with traditional oriental therapy(77.8%) and combined treatment of western and oriental therapy(92.3%) were observed. The effects of the symptoms were as follows; abdominal pain (16.3%), general body weakness(10.5%), nausea&vomiting (8.6%), diarrhea(6.7%) and etc, in orders. 4. Analysis of hematology attached by stomach cancer, maintenance and increasing of WBC(89.4%), RBC(63.6%), Hgb(62.3%), Platelet(95.6%) were observed. After taken Hangamdan, the safety of the liver and kidney were as follows; maintenance and decreasing of AST(85.3%), ALT(91.6%), BUN(84.8%), Creatinine(92.4%) were observed. 5. Analysis of IL-12 and IFN-γ attached by stomach cancer, increasing of IL-12(39.1%), IFN-γ(69.6%) were observed. 6. Analysis of QOL attached by stomach cancer, maintenance and improvement of combined treatment of western and oriental therapy(91%), traditional oriental therapy(85.2%) were observed. 7. Analysis of survival in patients with Ⅳ stage of stomach cancer, above 6 months(17.1%), 12 months(85.2%) were observed. 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(81.5%) and maintenance and improvement of combined treatment of western and oriental therapy(89.7%) were observed. Analysis of tumor marker attached by stomach cancer, maintenance of CEA(85.7%) were observed. 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(77.7%), combined treatment of western and oriental therapy(82.1%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for stomach cancer patients by combination with western therapy or alone.

To investigate the effects of hyperstimulation on the reproductive function, such as number of ovulated oocytes, fertilization rate, rate of blastocyst formation, number of survived implanted fetus, and effect on tubal transfer of embryos, ICR mice were injected intraperitoneally with PMSG, 5 IU and HCG, 5 IU and the comparative study with the control group was undertaken. In addition, mouse embryos, i.e., morulas or blastocysts were transferred to pseudopregnant recipient to investigate whether the embryo stge could effect on implantation rate. The results were as follows: 1. The number of ovulated oocytes after hyperstimulation was significantly increased, compared to the control group. The number of degenerated oocytes was also significantly increased. 2. The fertilization rate after hyperstimulation was not significantly different, compared with the control group. 3. The rate of blastocyst formation after hyperstimulation was significantly decreased, compared to the control group. 4. The number of survived implanted fetus was not significantly different with control group. 5. The speed of embryos’ movement in tube was significantly increased after hyperstimulation. 6. The significant loss of embryos was noticed just before implantation in hyperstimulation group. 7. After embryo transfer to recipient mothers, pregnancy rte with blastocysts was significantly increased, compared to pregnancy rate with morulas. This study suggests that hyperstimulation treatment on mice brings about significant loss of embryos just before implantation and its cause seems to be originated from developmental delay of the embryos.

The purpose of this study is to examine the effect of golf performance that are Driving Accuracy, Greens in Regulation, Putting on Green and score to using Virtual Reality Golf Program for 8weeks. For this study, 8 golf players, control group 4 and non-control group 4, of the H. University are selected, and they have played 18 hole rounding test t0 measurement golf performance at pre and after 8weeks. The collected data was used t-test For data analysis, and the results of this study was as follows; 1) Statistically, Contra[ group was significant incresed the driving accuracy and greens in regulation(p<.05), and decreased the scan on golf simulation rouding between pre and past(p<.05). 2) Statistically, non-control group was not significant changed driving accuracy, green in regulation, putting, and score on 18 hole rounding between pre and post. 3) Statistically, control group was significant increased the driving accuracy and greens in regulation(p<.05), and decreased the score on 18 hole rouding between pre and past(p<.05).
