The aim of this study was to investigate the growth performance between two different crossbred strains of Korean native chickens denoted as 1E and 2E with a white semibroiler (LL) from hatch to d-84 post-hatch. A total of 450 one-day-old chicks were randomly distributed into cages which included 15 replicate cages each for 1E and 2E with 9 replicate cages for LL. A three phase feeding program was used as a starter (Day 1 - 35; crude protein [CP] 20.3%; metabolizable energy [ME] 3,059 kcal·kg^-1), grower (Day 36 - 56; CP 18.6%; ME 3,123 kcal·kg^-1) and finisher (Day 57 - 84; CP 16.7%; ME 3,187 kcal·kg^-1). The results revealed that LL had a higher (p < 0.05) BW during d-8 to d-84 compared with the other two cross breed groups. A higher (p < 0.05) ADG was observed from the LL during the entire period except from d-1 to d-14 and d-71 to d-84 when compared with 1E and 2E. Shank length did not vary (p > 0.05) between the strains, despite LL having a SL that was 2.86% higher (p < 0.05) when compared with the other strains from d-15 to d-21 post-hatch, and 1E had a SL that was 2.28% (p < 0.05) higher when compared with the other strains during the first week of the experiment.

I have studied life of Yoon-Dong-Li(尹東里), who applied Un-Ki(運氣) theory to medicine during Suk-Jong(肅宗) to Joong-Jo(正祖) in Yi-Dynasty and also studied his existing writings named ${\ll}$Cho-Chang-kyeol${\gg}$ (草窓訣). The referenced original work prints were based on 1980's print of Chung-Ku oriental medical society and National Central Library and The academy a korean studies possessed print. Studied with these books, I have concluded as follows. 1. Yoon-Dong-Li(尹東里) courtesy name is Ja-Mi(子美), pen name is Cho-Chang(草窓). He was born in 1705, Suk-Jong(肅宗) 31yrs, and died in 1784, Jeong-Jo(正祖) 8yrs in Yi-Dynasty. He had lineage of third-generationed-doctor and learned medicine from his uncle, Yoon-Woo-Kyo(尹雨敎). His father Yoon-Yi-Kyo(尹이敎) gaved him second influence. 2. Confucianal physician in Ming Dynasty You-Bu(劉溥) respected Ju-Ryeom-Kye(周溓溪), confucianist in Song-Dynasty and You-Bu(劉溥) does not removed grass in front of window (because in chinese, Cho-Charig(草窓) means grass in front of window), and named himself Cho-Chang(草窓). Yoon-Dong-Li(尹東里) followed this suit so called himself Cho-Chang (草窓). 3. The main contents of ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣), (運氣衍論) was written in 1725, when Yoon-Dong-Li(尹東里) was 21yrs old and printed in 1736. The other part of ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣), (用藥篇) was written in 1746. These two parts were not written in the satre time. The (運氣衍論) was written llyears earlier than (用藥). Two parts were combined another day and named (草窓訣). 4. Existing ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣) is transcribed printing with the con tent of "Five elements motion and the six kind of natural factors theory" (五運六氣設). Each edition is generally similar in content, but also has different points each other so naw we hardly finds a complete set of works. 5. ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣) is a first technical book which treats of Un-Ki(運氣) theory in korea. 6. The contents of (運氣衍論) of ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣) is mechanism of diease according to excess and insuffciency of five elements motion and six kinds of nalural faclors.and symploms and priscriptions, includes variated priscriptions. 7. Two parts in (運氣衍論) of ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣), 'Sang-tong' (相通) and 'Kak-Tong' (各通), threats of mochanisim of the disease according to five elements. with the principle of inter-promoting and inter-acting, in the change of ten heavenly stems and five elements motion. 8. In the (用藥篇) of ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣) describes priscription for clinical application according to Un-Ki(運氣) and also records about misuse of medicine. 9. In the ${\ll}$Cho-Chang-Kyeol${\gg}$ (草窓訣), most of priscription are common using one, which also found in ${\ll}$Dong-$\breve{U}$i-Bo-Garm${\gg}$ (東醫寶鑑) and there are few of priscriptions hy Yoon-Dong-Li(尹東里).

The following study was undertaken in order to seek the acupuncture operation method of $\ll$Sang Han Lun(傷寒論)$\gg$ Liu-Jing-Bian-Zheng(六經辯證). Based on the documents quoted in $\ll$Sang Hang Za Bing Lun Xu Wen(傷寒雜病論 序文)$\gg$ of "Zhang, Zhong-Jing(張仲景)", the relativity of the theory of Jing-Mai(經脈) and Liu-Jing-Bian-Zheng of convalescence, and from the Liu-Jing-Bing(六經病), the origin and implication that caused Tai- Yin-Bing(太陰病) to form was studied on the basis of acupuncture medicine publications and the commentary writing of $\ll$Sang Han Lun$\gg$. As a result of the foregoing study, the author has written the following acupuncture operation on the basis of a summarized Tai-Yin-Bing for $\ll$Sang Han Lun$\gg$ Liu-Jing-Bian-Zheng. Results : $\ll$Sang Han Lun$\gg$ Liu-Jing-Bian-Zheng has succeeded and was developed based on Liu-Jing-Fen-Zheng(六經分證) of $\ll$Su Wen Re Lun(素問 熱論)$\gg$. In addition, the summary of Liu-Jing-Bing became the general principle of Fen-Jing(分經) and Ding-Zheng(定證) that may be applicable to Fenghan(風寒), Wenre(溫熱), Lili(疫려) and Zabing(雜病). 2. Most commentators of $\ll$Sang Han Lun$\gg$ in the Song, Ming and Ching Dynasties of $\ll$Sang Han Lun$\gg$ interpreted the Tai-Yang-Bing in physiological and pathological aspects of Rong-Wei(榮衛) as the disease of the spleen meridian. 3. From the Liu-Jing-Bing of $\ll$Sang Han Lun$\gg$, the region of acupuncture treatment of Tai-Yang-Bing is treated with the needle from the point of view of Bing-Zheng-Lun-Zhi(辨證論治) with the basis of the important region of acupuncture of the spleen meridian.

Strengthening mechanisms in an ordered intermetallic compound containing coherent precipitates of lower antiphase boundary energy than the matrix were investigated on the basis of the interaction between the deformation induced dislocations and the disordered precipitates in an $Ll_2$ ordered $Ni_3Al$-based alloy. Extra work was needed to pull out the dislocations from the precipitate, which was dependent on the difference in the antiphase boundary energy between the matrix and the precipitate, as well as the size and volume fraction of the precipitate. The strength of the $Ll_2$ ordered ${\gamma}^{\prime}$ phase containing fine precipitates of the disordered ${\gamma}$ phase was examined using the proposed model. The model can explain almost quantitatively the age hardening behavior of the $Ll_2$ ordered ${\gamma}^{\prime}$ phase.

Although various raw plant materials have been demonstrated to exert anti-obesity effects to a greater or lesser extent in both humans and animals when they are used to supplement the diet, it has not been shown extensively that they influence adipocyte cell differentiation involving lipid metabolic gene expressions. Using a well-established 3T3-L1 preadipocyte differentiation system, we decided to look into molecular and cellular event occurring during adipocyte differentiation when raw plant materials aye included in the process, in an effort to demonstrate the potential use of a screening system to define the functions of traditionally well-known materials. To these ends, the effects of ethanol (EtOH) or EtOH/distilled water (DW) extracts of Wax Gourd were examined using cytochemical and molecular analyses to determine whether components of the extracts modulate adipocyte differentiation of 3T3-Ll preadipocytes in vitro. The cytochemical results demonstrated that EtOH or EtOH/DW extracts did not affect lipid accumulation and cell proliferation, although the degree of lipid accumulation was influenced slightly depending on the extract. EtOH extract was highly effective in apoptotic induction during differentiation of 3T3-Ll preadipocytes (p<0.05). Reverse transcription-polymerase chain reaction (RT-PCR) analysis of lipoprotein lipase (LPL), Uncoupling protein (Ucp) 2, 3 and 4 also showed that while LPL expression was not influenced, Ucp2, 3 and 4 were up regulated in the EtOH extract-treated group and down regulated in the EtOH/DW extract-treated group. These changes in gene expressions suggest that the components in different fractions of Wax Gourd extracts may modulate lipid metabolism by either direct or indirect action. Taking these results together, it was concluded that molecular and cellular analyses of adipocyte differentiation involving lipid metabolic genes should facilitate understanding of cellular events occurring during adipocyte differentiation. Furthermore, the experimental scheme and analytical methods used in this study should provide a screening system for the functional study of raw plant materials in obesity research.

To determine the effects of guar suksolgi on blood glucose and lipids in type-ll diabetic subjects, a piece of guar suksolgi(36.3g, 54Kcal) was administered to eight patients for 3 weeks every meal. No significant differences occured indietary intakes and body weight before and after the treatment. Fasting blood glucose levels were decreased from 132.38mg/dI to 114.75mg/dI after the treatment, but not statistically significant. Blood TG levels were increased from 159.13mg/dI to 175.00mg/dI after the treatment, but not statistically significant. Excluding one patient who had extremely high TG level, blood TG levels tended to be decreased from 148.00mg/dI to 121.00mg/dI. TC LDL-c, HDL-c levels were decreased after the treatment, but not statistically significant. HbAIC concentrations were decreased from 8.54mg/kI to 7.80mg/dI after the treatment, but not statistically significant. In the case of three patients who had had normal fasting blood glucose levels, blood glucose levels tended to be decreased at postprandial 30, 60 minutes, and blood insulin levels tended to be decreased at postprandial 30, 60, 90, 120 minutes, although none of the levels were statistically significant. Therefore, if guar suksolgi is adinistered to type-ll diabetic subjects being more hyperglycemic than our patients, their blood glucose and lipids will be decreased significantly.

전통 재래식 메주 3종을 수집하여 호기성 생균수, 유산균수, 효모 및 곰팡이의 수를 측정한 결과 각각 $10^7\sim10^8$ CFU/ g, $10^6\sim10^8$ CFU/g, $10^7\sim10^8$ CFU/g의 분포를 나타내었고, 일반적으로 메주의 발효에 가장 크게 관여하고 있는 효모 및 곰팡이이 외에도 유산균 역시 메주의 발효에 깊이 관여하고 있는 주요 균주인 것으로 나타났다. 재래식 메주로부터 몇 종의 유산균을 분리한 후, 3종의 우수균주를 선별하여 동정을 실시한 결과, Leuconostoc mesenteroides, Lactobacillus plantarum, Lactococcus lactis로 밝혀졌으며, 이들을 각각 Lm-SMm, Lp-SMm, Ll-GAm로 명명하였다. 3종 유산균의 효소 활성을 측정한 결과, 모두 protease, lipase, $\alpha$-amylase 활성을 나타내었고 특히 Ll-GAm이 상대적으로 높은 효소 활성을 나타내었다. DPPH를 이용하여 항산화 효과를 측정한 결과, Lm-SMm, Lp-SMm, Ll-GAm은 각각 45%, 48%, 60%의 free radical 소거 효과를 나타내었고, MTT assay를 이용하여 HT-29 인체 결장암 세포 성장억제 효과를 측정한 결과 각각 45%, 67%, 70%의 성장억제 효과를 나타내었다. 따라서 전통메주로부터 분리한 우수한 유산균은 장류제조 산업에 있어서 적용성이 있을 것으로 생각되어지며, 메주 제조에 있어서 스타터로 사용되었을 때 장류제품의 품질을 향상시킬 수 있을 것으로 기대된다.
