Objective: I carried out this study for research on thermographic change of DITI by Sugi Therapy. Methods: This study was conducted on 22 normal cases (M : F =4:18) with no past history to observe the effect of Sugi Therapy. 22 cases were divided into 2 groups. One group is a control group treated by only Acupuncture Therapy. The other group is a treatment group treated by Acupuncture Therapy and Sugi Therapy. I measured temperature of abdomen and palm by DITI (Digital Infrared Thermographic Imaging) before and after treatment Result: 1. Overall the temperature difference of the treatment group was bigger than that of the control group. 2. On the palm, the average value of the treatment group was -0.56±0.70, which is lower 10 times than -0.06±0.91 of the control group. 3. On Chung-wan(CV12), the average value of the treatment group was 1.20±0.49, which is 2.15 times higher than 0.56±0.44 of the control group. 4. On Kwanwon(CV4), the average value of the treatment group was 0.77±0.73, which is 1.38 times higher than 0.55±0.39 of the control group. 5. To compare the temperature difference on the palm, Chung-wan(CV12) and Kwanwon(CV4) before and after treatment, the order is like this :Chung-wan(CV12) > Kwanwon(CV4) > palm of all treatment group and control group. Conclusion: I came to a conclusion that Sugi Theraphy is likely to work better with Acupuncture Therapy better than only Acupuncture Therapy, especially on Chung-wan(CV12).

We investigated if Chlorella vulgaris (CV) has protective effects on cadmium (Cd) induced liver damage in male Sprague-Dawley (SD) rats. Forty rats, aged 5 weeks old and weighed 90-110g, were divided into a control (with Cd free water), 50 ppm of $CdCl_2$ in drinking water treated groups (Chlorella 0% diet group (Cd/CV0%), Chlorella 5% diet group (Cd/CV5%) or Chlorella 10% diet group (Cd/CV10%). All the rats had freely access to water and diet for 8 weeks. The results show that body weight gain and relative liver weight had significantly lower in Cd/CV0%-treated group than in Cd/CV-treated groups. Hepatic Cd contents showed significantly less by feeding CV (P<0.05). Cd/CV0%-treated rats had significantly (P<0.05) higher hepatic T-MTs, and Cd-MTs concentrations, compared to Cd/CV5% or Cd/CV10% treated rats. The MT I/II mRNA was expressed in the liver of all experimental rats. Its expression was more increased in Cd/CV5%- or Cd/CV10%-treated rats, compared to control and Cd-treated rats. Thus, this study suggested that CV would have a protective effect on Cd-treated liver injury by the reduction of Cd concentrations and stimulation of Cd-MT binds in the liver. However, more studies are needed to identify the proper mechanism of CV and liver toxicity.

The effect of Chlorella vulgaris (CV) on the urinary excretion of di-ortho PCB congeners (PCB-138, -153) was investigated. Sprague-Dawley rats (6-weeks-old, n=10 rats/group) were randomly divided into one control (0CV) or 2% CV (2CV) or 5% CV (5CV) or 10% CV (10CV) groups, respectively. Composition of normal and chlorella meal-based diet were made up of 30% casein, 15% cornstarch, 50% sucrose, 5% cellulose, 5% coconut oil, 3.5% mineral mixture, 1 % vitamin mixture. All rats had free access to water and diet for 4 weeks. A significant increase in both PCB 138 and 153 in urinary level was detected in CV fed groups, 540% and 167% for 2CV, 155% and 89% for 5CV, 114% and 144% for 10CV group, respectively, when compared with their controls. These findings suggest that CV may have potential to eliminate body burden levels of dioxin-like PCB compounds.

"Chamgreen" was a domestically developed rye (Secale cereal L.) cultivar in South Korea, known for its quick heading, cold resistance, and abundant yield of forage. The heading date of cv. 'Chamgreen' averaged April 17th, which was 4 days earlier than the standard cv. 'Gogu'. In the early harvesting stage, the plant height reached an average of 119 cm, 7 cm taller than the standard cv. 'Gogu', and the number of spikes per m² was 865, slightly less than cv. 'Gogu's 897. Resistance to cold and powdery mildow remained consistent across four regions nationwide over three years, with an average rating of 0, matching cv. 'Gogu'. Lodging resistance was also rated at 2, equivalent to cv. 'Gogu'. The dry matter yield of cv. 'Chamgreen' was 9.1 tons per hectare, 15% higher than cv. 'Gogu's 7.9 tons. Although the protein content in cv. 'Chamgreen' was 13.5%, 1.6% lower than cv. 'Gogu', the total digestible nutrients (TDN) content was 5.81 tons per hectare, 20% higher than cv. 'Gogu'. Due to its strong cold resistance, cv. 'Chamgreen' allows for winter cultivation through double cropping and rotation systems in various regions across the country.

Objectives : Nocturnal enuresis is common disorder in children and has important negative effects on the self-image and performance of children. Thus Successful treatment needed to increase self-esteem. Many studies of this symptoms were reported. But electro-acupuncture treatment not reported in Korea. Methods : We treated three cases enuretic children with different types. Their diagnosis were non-monosymptomatic primary, monosymptomatic primary, monosymptomatic secondary nocturnal enuresis. We used electro-acupuncture on Zhongji(CV3), Guanyuan(CV4) for 20 min. To investigate relapse. at least for 4 months after the end of the therapy we followed-up by telephone. Results : After treatment, diurnal urinary symptoms, such as increased frequency of urination, urgency, incontinence were dramatically improved. And the number of wet night decreased with nocturia and delayed wetting time. Compared to pre-treatment, findings, the number of wet nights decreased 80% or more. Conclusion : All of them tolerated electro-acupuncture well and kept reduction at least for 4 months follow-up. Further study is needed with more cases.

분류층 가스화기에서 슬래그의 점도 변화는 가스화기 운전 온도을 결정하는 중요한 요소이다. 본 논문에서는 국내 가스화 대상탄 중 결정슬래그의 거동을 보여주는 5개 탄 슬래그의 $T_{cv}$를 문헌의 경험식과 Factsage를 이용한 평형계산으로 예측하고, 각 방법의 실용성을 조사하였다. 경험식으로는 두개의 모델이 사용되었는데 각각 회분용융시험의 $T_h$와 슬래그의 5개 주성분 농도를 이용하였다. $T_h$를 이용한 모델은 $20{\sim}100^{\circ}C$ 높은 $T_{cv}$를, 5개 주성분을 이용한 모델은 $80{\sim}120^{\circ}C$ 낮은 $T_{cv}$를 예측하였다. 평형계산에서는 액상선 온도로 $T_{cv}$를 구하였다. 평형계산에 주 4 성분만을 사용하였을 경우 측정된 $T_{cv}$보다 높은 온도가 예측되었다. 액상선 온도는 부 성분의 농도에 매우 민감하여 MgO와 $Na_2O$의 추가는 액상선 온도를 낮추어 주었다. 평형계산에서 석탄의 주성분뿐만 아니라 부성분을 모두 포함시켰을 때 측정된 $T_{cv}$에 가장 근접한 결과를 얻을 수 있었다. 또한 $Cr_2O_3$ 계열의 내화재가 사용되었을 경우, $T_{cv}$의 좀 더 정확한 예측을 위하여 용해 내화재의 농도도 평형계산에 포함시켜야함이 확인되었다.

Correction factors based on the catch ratios of egg and larval densities in the southern waters of Korea were estimated for anchovy Engraulis japonica. This was undertaken in order to adjust ichthyoplankton data from different sampling methods, gear types and time. Samples were collected during ichthyop1ankton surveys in Korean waters from 1983 to 1994. The ratios for egg densities obtained in vertical tows with a NORPAC net (ring $\Phi$, 45 cm) compared to those obtained in oblique tows with a KOB net (ring $\Phi$, 80 cm) were 0.86 (CV = 0.65), 1.22 (CV = 0.36), and 0.93 (CV = 0.42) for early, middle, and later developmental stages, respectively. The ratios for larval densities for vertical and oblique tows varied depending on size. For yolk-sac and small larvae (< 4 mm), the ratios were 3.08 (CV = 0.45) and 1.98 (CV = 1.34), while those of 4-6 mm, 6-8 mm, and 8-10 mm larvae were 0.44 (CV = 1.31), 0.45 (CV = 1.70), and 0.56 (CV = 2.50), respectively. Ratios of day/night densities for larvae of 4-10 mm lengths were lower (0.01-0.06) in offshore catches than values obtained in coastal areas (0.440.46) and similar values (0.16-0.04) for vertical and oblique tows. Our results indicated that vertical towing is more efficient for sampling early life stages (from eggs to larvae less than 4 mm long), while oblique towing is more efficient for larvae longer than 4 mm due to depth preferences for each developmental stage (e.g., changes in egg buoyancy and vertical migration oflarvae).
