Objectives The purpose of this study is aimed at diagnosing and suggesting treatment plans for commonly seen clinical manifestation of heat symptom in the upper body and coldness in the lower body, also known as hot above, cold below syndrome. Methods Various reasons attribute to the presence of hot above, cold below syndrome, but mainly contributed by blockage of normal Qi flow by abnormality of heart-kidney root, spleen-stomach axis, and liver-lung axis. Diagnosing these abnormalities and timely alleviation to the healthy state is presented in the study. Results 1For heat in the upper body, Huang Lian Jie Du Tang(黃連解毒湯), CF, or JsD pharmacopuctures are injected on GB21, GB20. Qi stagnation in the thoracic area is treated with BUM injection on CV17. For impairment of transportation and transformation in the middle energizer, BUM pharmacopuncture is injected on CV12. Coldness in the lower energizer was relieved by bee venom or Sweet BV(Bee Venom free from enzymes) on CV6. Conclusion Above proposed methods of regulating water-fire were effective in treating hot above, cold below syndrome in clinical manifestations. But once the symptom subsides, treatment focused on eliminating innate cause should be rendered to achieve more successful results.

The successful restoration program requires a comprehensive understanding of variables influencing seedling efficiency. Below-ground is hypothesized to have a major impact on seedling performance of species when planted in agriculture, and degraded areas with different types of mulching. This study investigated on Sg. Terla Forest Reserve in Cameron Highlands Pahang, Malaysia. In this study randomized complete block design (RCBD) was used. The excavation method was applied to study the root system development, above, and below ground biomass distributions under different types of mulching: coconut mulching (CM), oil palm mulching (OM), plastic mulching (PM) and control (CK). The root diameter, main root length, lateral root length, root coiling, and root direction toward to sun were recorded. The results in this study indicate that mulching had significant effect on root diameter, main root length, and root distributions among treatments while for lateral root length, root: shoot ratio, dry biomass distributions, and above and below ground biomass did not showed significant effect among treatments. The highest values for root diameter, lateral root length, main root length, root distributions, dry biomass distributions and above and below ground biomass were showed in CM treatments. However 75% of root coiling was observed in seedlings between treatments.

Open heart surgery begun at 1959 in Korea. From that time to 1979, the surgery was performed below 100 cases in a year. However,that was performed above, 1,000 cases in a year from 1981. During the recent three years, i.e., 1985, 1986, and 1987, the annual operative cases were 3614,4503, and 4906, and then the mortality rates were progressively decreased to 6.2%, 5.3 %, and 5.0 %. In these time, overall mortality rate above 1 year old was 5.0 % versus that below 1 year old 17.9 9o in congenital heart diseases. These results are statistically different between two groups. Of the valvular heart disease cases, which occupied 97 % of total acquired heart disease, individual incidence was in mitral 68 %, and aortic 28%. The operative method was mainly valve replacement. Operative mortality for valve surgery in total was 4.4 %. Until 1985, bioprosthetic valve was frequently implanted but mechanical valve has been done more frequently in these days. Coronary artery bypass graft was large portion [67 * 75 %] of open heart surgery in western, but was below 1 % in Korea. However our diet patterns have been changed. Therefore we think the incidence of coronary artery disease will be increased. So we will be familiar to this field.

In this paper, theoretical basis of stereoscopic display is investigated and programmed to shaw the application which could be used in the Virtual Reality (VR), especially for ship design. Stereoscopic is based on the seperated view point of left and right eyes on the screen and making 3 dimensional image. There different stereoscopic methods such are red-blue, interlacing, side-by-side and above-below are imvestigated and implemente to shaw the simple ship model and inside of ship. To shaw the 3 dimensional view, OpenGL is used to make program by implementing the logic of stereoscopic. Simple models and ship design are implemented to survey the applicability of stereoscopic for ship design. The best way is to use two projectors to emit interlaced shape. It is expected to imply this technique in the VR application for ship design.

Al/a-Si:H/Mo 구조의 MIM(Metal-Insulator-Metal) antifuse를 제작하여 antifuse의 I-V 특서을 조사하고, 온저항의 분포를 구하였다. 제작된 antifuse의 누설전류는 1pA/$\mu\textrm{m}^2$이하였고, 프로그래밍 전압은 10~11V 내에 분포하였다. 프로그램 후 온저항은 대부분 10~20 Ω이었고, 20%정도는 100$\Omega$이상의 분포도를 보였다. 이러한 온저항 분포의 편차와 저항값을 줄이기 위해 이미 프로그램된 antifuse에 다시 전류를 주입하는 재 프로그래밍 방법을 시도 하였다. 이 방법을 통하여 100$\Omega$이상의 온저항을 가지는 antifulse를 다시 50$\Omega$이하로 낮출 수 있었다. 재 프로그래밍 방법을 사용한 antifuse는 한번만 프로그래밍 했을 때 보다 더욱 더 균일하고 낮은 온저항 분포를 가졌다.

Nitrogen(N) and phosphorus(P) in surface streams mainly lead to euthrophication. It aggravates water quality and consequently increases the purification costs. As a resolution of water contamination caused by household drainage through irrigation route by 70% of the 1,300 community residents in Eum-Am Myun, Seo-San city, was implemented biological self-purification method by growing Oenanthe Javanica along the polluted water tunnel. The contaminated water was efficiently purified after passing the dropwort field; DO conc. of effluent water was increased 8.3∼61.9% after through the drop wort field. HRT of experiment system was changed 0.05∼1.50/day. 50% of BOD was eliminated at the range above 12 mg/l of Influent BOD conc. Also, 50% of COD was eliminated at the range above 30 mg/l of Influent COD conc. Finnally, the influent T-N loading at range below 1.5 g/m$^3$/d reduced 50% of Influent T-N conc., and so did influent T-P loading at the range below 0.03 g/m$^3$/dwas reduced 50% of Influent T-P conc.

The aim in this study was to obtain the basic data for estimation of optimal mating time and ovulation time by finding out the relationship between vaginal cytology and reproductive hormone profiles during the estrous cycle in 36 Korea Jin-do bitches. A characteristic features of vaginal cytology during the estorous cycle were the high proportion of superficial cell, anuclear cell and erythrocyte in proestrus, superficial cell, anuclear cell and erythroucyte in estrus, parabasal cell, small and large intermediate cell and leukocytes in diestrus, and parabasal cell and small intermediate cell in anestrus, respectively. Cornification index(CI) was the high proportion in proestrus and estrus, then it was decreaed in diestrus and anestrus. It indicated that the CI was significantly high proportion in proestrus and estrus in comparison with the other phases. Plasma progesterone concentration was below 1.0ng/ml at the first day of vulval bleeding in pregnant and non-pregnat bitches, and then it was increaed slowly. When Day 0 was timed from the day that plasma progesterone concentration was first increased above 4.0ng/ml, plasma progesterone concentrations at Day 0 in pregnant and non-pregnant above 4.0 ng/ml, plasma progesterone concentrations at Day 0 in pregnant and non-pregnant bitches were $5.2{\pm}0.3ng/ml and 5.7{\pm}0.5ng/ml$$46.5{\pm}3.3 ng/ml$ in pregnant bitches and at Day 20 with $39.8{\pm}0.1ng/ml$ in nonpregnant bitches. It indicated that plasma progesterone concentration was higher in pregnant bitches than in non-pregnant bitches. Hereafter plasma progesterone concentration was decreased steadily. At Day 63 which is parturition day, plasma progesterone concentration was decreased below 1.0ng/ml with $0.8{\pm}0.2ng/ml$ in pregnant bitches whereas in the non-pregnant bitches at Day 75 were decreased below 1.0ng/ml with 40.5{\pm}0.4ng/ml$. Plasma progesterone concentrations was maintained below 1.0ng/ml during anestrus in all of them. The plasma estradiol-17 $\beta$ concentration was increased above 1.0 pg/ml at the first day of vulval bleeding and it showed a peak Day-1 with 38.2 pg/ml. Thereafter it was sharply decreased after Day 0, which was the day that plasma progesterone concentration was first increase above 4.0ng/ml, and was maintained below basal levels. In relationship between CI and reproductive hormones, plasma estradiol-17 $\beta$concentration showed a peak at Day-3 and CI showed a peak at Day-1 which was the second day after plasma estradiol-17 $\beta$ peak, and plasma progesterone concentration was first increased above 4.0ng/ml at Day 0 which was the first day after CI peak. CI was first increased above 80% at Day-6 which was the third day before plasma estradio-17 $\beta$ peak and it was maintained above 80% between Days-6 and Day 3 during 10 days, and showed above 90% at Day-3 which was the day that plasma estradiol-17 $\beta$peak and was maintained above 90% between Day-3 and Day 3 during 7 days. In conclusion, ovulation in Koran Jin-do bitches occurred at the first day after CI peak, at the third day after plasma estradiol-17 $\beta$peak and the day when plasma progesterone concentration was first increased above 4.0 ng/ml. And it was estimated that the optimal mating time was the day when the CI was maintained above 90% and plasma progesterone concentration was between 3.0~8.0ng/ml. Therefore plasma progesterone concentration measurement was used for determination of an accurate ovulation time and the optimal mating time but also vaginal cytology, which is low-priced with equipment and is the simple examination method, was reliable method for estimating estrous cycle, optimal breeding time and ovulation time in Korea Jin-do bitches.

The ride comfort is more important in the train speedup. Generally, it is defined as the vehicle vibration. There are many studies on evaluation method of ride comfort for railway. But the ride comfort for Korean high speed train(HSR 350x) has been assessed by statistical method according to UIC 513R. It is very difficult for HSR 350x to run at constant speeds above 310 km/h during 5 minutes required in UIC 513R because of the same operational condition as KTX and the infrastructures. In this paper, the ride index at high speed above 310 km/h has been predicted by using those obtained below 310 km/h and the comfort for HSR 350x has been reviewed in these speeds.

The present study was conducted to investigate the isolation frequency, biochemical prop erties and antimicrobial susceptibility of B. bronchiseptica isolated from slaughtered pigs during the period from March to December, 1992. In Kyeonggi province. A serological survey for antibody of B. bronchiseptica in 200 slaughtered pigs was carried out by agglutination and tetrazolium reduction methods. The results were summarized as follows ; 1. From 80 slaughtered pigs, 27(33.8%) case were isolated and all isolate strains were resistant to Penicillin, Streptomycin, Chloramphenicol, Tetracycline and Ampicllin, while the majority of them were susceptible to Gentamicin, Cloxacin, Colistin, Neomycin, and Kanamycin. 2. Incidence of B. bronchiseptica antibody in 200 slaughtered pigs were measured by agglutination and tetrazolium reduction methods. Agglutination method was shown 38 (19%) of 200 with a titer of below 1：20 and 20(10%) of 200 with a titer of above 1：640. Tetrazolium reduction method was observed 33(16.5%) of 200 with a titer of below 1 : 20 and 32(15%) of 200 with a titer of above 1：640. 3. LSD analysis indicated that the difference of the responses between agglutination test and tetrazolium reduction test was not significant.
