Many bovine genetic diseases are currently unidentified in Korea because of the relatively low monitoring systems in the livestock farms. The molecular detection system using PCR-RFLP of two genetic diseases, namely Band 3 (Erythrocyte Membrane Protein Band Ⅲ) and CHS (Chediak-Higashi Syndrome), have been identified in Japan and used for screening large number of cattle whether each individual has the genetic disease or not. Using the 22 unrelated Korean cattle (Hanwoo) individuals, molecular detection system based on PCR-RFLP have been investigated, which can be distinguishable carriers for the genetic diseases. Even though we could not found the causative mutations for two genetic diseases, the PCR-RFLP techniques used in this study are very valuable for the screening the genetics diseases in Korean cattle, especially for the proven or candidate bulls.

상악 전치부 후방 견인 시의 이동 양상 및 응력 분포를 건조 두개골을 전산화 단층 촬영에 의해 3차원 영상화한 유한 요소 모델 상에서 알아보고자 하였다. 피질골 절단술의 시행 여부와 고정원, 힘의 작용점을 각기 달리 설정하여 8개의 실험군을 구성하여 비교하였다. 통상적인 T-loop을 이용하여 공간폐쇄를 하는 경우 전치부는 후하방으로 경사이동 하였으며, 구치부에서도 약간 전방 이동하였다. 피질골 절단술을 동반하여 전치부를 견인한 경우, 전치부 골편에서의 응력 분포가 전반적으로 넓게 분포되었으며, 전치부 경사의 정도가 적은 반면에 변위량은 훨씬 더 많았다. 협측에서의 견인 시 상악 협측에 식립된 미니 임플랜트와 견치 power arm간에 견인력을 가한 경우가 미니 임플랜트로 고정원이 강화된 제2소구치와 견치 브라켓 간에 견인력을 가한 경우보다 전치부의 후하방 경사 정도가 적었다. 구개측에서 power arm에 대한 견인 시 정중구개봉합 부위에 식립한 미니 임플랜트로부터 견인력을 가한 경우가 상악 제1, 2대구치 간 구개면에 식립된 미니 임플랜트로부터 견인력을 가한 경우보다 전치부의 후하방 경사 정도가 컸다. 이러한 결과로써 치아이동 시 피질골 절단술의 효과와 저항중심에 대한 교정력 벡터 조정의 의미를 확인할 수 있었다. Objective: The purpose of this study was to evaluate the displacement pattern and the stress distribution shown on a finite element model 3-D visualization of a dry human skull using CT during the retraction of upper anterior teeth. Methods: Experimental groups were differentiated into 8 groups according to corticotomy, anchorage (buccal: mini implant between the maxillary second premolar and first molar and second premolar reinforced with a mini implant, palatal: mini implant between the maxillary first molar and second molar and mini implant on the midpalatal suture) and force application point (use of a power arm or not). Results: In cases where anterior teeth were retracted by a conventional T-loop arch wire, the anterior teeth tipped more postero-inferiorly and the posterior teeth moved slightly in a mesial direction. In cases where anterior teeth were retracted with corticotomy, the stress at the anterior bone segment was distributed widely and showed a smaller degree of tipping movement of the anterior teeth, but with a greater amount of displacement. In cases where anterior teeth were retracted from the buccal side with force applied to the mini implant placed between the maxillary second premolar and the first molar to the canine power arm, it showed that a smaller degree of tipping movement was generated than when force was applied to the second premolar reinforced with a mini implant from the canine bracket. In cases where anterior teeth were retracted from the palatal side with force applied to the mini implant on the midpalatal suture, it resulted in a greater degree of tipping movement than when force was applied to the mini implant between the maxillary first and second molars. Conclusion: The results of this study verifies the effects of corticotomies and the effects of controlling orthodontic force vectors during tooth movement.

In this paper, we report some sorts of result obtained by investigating the exhibits which had been submitted for "The National Exhibition of Science"and "The Science Exhibition for the Students of Cheju-do"during the last ten years and by putting the questions to the science teacher of the teacher of the middle and high schools in Cheju-do. Up to the half number the exhibits are occupied by the field of physics and biology. Almost the exhibits (above 90%) have the contents related to those of the current curriculum. However, 30.2% of the respondents only believe that their students may put the exhibits to practical use in learning. Many respondents replied that they could have not participated in the exhibition of science because they were in heavy duty and the fiscal support were not only so limited but also not sufficient enough to make an excellent work.

박필숙,강진순,정승용,박재옥,김행자 慶尙大學校 1987 論文集 Vol.26 No.1

체중 60~65㎏의 wistar계 숫쥐에게 cholesterol 무첨가식이에 물과 kale 녹즙을 각각 급여하여 혈청중 총 cholesterol 농도, HDL-cholesterol 농도, 간장중의 총 cholesterol 농도, 혈청 및 간장중의 TG와 PL의 농도 그리고 과산화지질 농도를 측정하여 다음과 같은 결과를 얻었다. 1) 혈청중 총 cholesterol 농도는 cholesterol 무첨가식이군인 1,2군산 cholesterol 첨가이식군인 3,4, 5군간에서 각각 유의성이 없었다. HDL-cholesterol 농도는 cholesterol 무첨가식이군인 1,2군과cholesterol 첨가이식이군인 3,4,5군에서 kale 녹즙을 급여한 군이 유의적으로 높았다. 2)혈청의 중성지방농도는 전 군간에 유의성은 없으나 물ㅇㄹ 급여한 군보다 kale 녹즙을급여한 군에 있어 약간 낮은 경향이었다. 혈청의 인지질 농도는 cholesterol 무첨가식이군 및 cholesterol 첨가이식군 모두 물을 급여한 군보다 kale 녹즙을 급여한 군이 유의적으로 높았다. 3)간장의 총 cholesterol 농도는 cholesterol 첨가식이군에 있어 물을 급여한 군이 약간 낮은 경향이었다. 4)간장의 중성지방농도는 cholesterol 무첨가식이군에 비해 cholesterol 첨가이식군인 3,4,5군이 유의적으로 높았으며, 이들 군간에 있어서는 kale 녹즙혼액군이 비교적 낮았다. 간장 인지질농도는 cholesterol 첨가식이군인 3,4,5군간에 있어 kale 녹즙과 녹즙혼액을 급여한 3,4,군이 비교적 낮았다. 5)혈청 및 간장의 과산화지질농도는 cholesterol 첨가이식군인 3,4,5군이 무첨가식이군에 비해 대체로 낮았으며 또한 kale녹즙과 녹즙혼액을 급여한 군에 있어 유의적으로 낮았다. 이상의 결과로 보아 kale 녹즙의 섭취는 혈청 HDL-cholesterol 농도의 상승효과가 있고 간장 중 cholesterol 및 인지질의 농도를 다소나마 저하시키며 또한 혈청및 간장의 과산화지질농도의 지하작요이 있으므로서 혈청 및 간장의 지질개선효과가 있는 것으로 사료된다. The effect of kale juice, Brassica oleracea, on lpid components in serum and liver were investigated by feeding male rats of wistar for four weeks. And the concentrations of T-cholesterol,phospholipid, triglyceride and lipid peroxide in serum and liver were analysed along with the HDL-cholesterol concentration of serum . The results were as follows: 1)There was not found ny significant influence on the concentration of T-cholesterol in serum, butsome of relatively higher inluence but some of relatively higher influence on the HDL-cholesterol concentration. 2)For the group fed with 100% kale juice the concentration of triglyceride was shown lower than for any other groups, while that of phospholipid was shown higher. 3)The concentration T-cholesterol in liver was shown a little lower for the kale juice groups. 4)The concentration of triglyceride in liver was remarkably decreased in the 100% kale juice group in comparison with other groups, whiel the phospholipid concentraion was not. 5)Lipid peroxide values in serum and liver were relatively decreased in the kale juice groups compared to other group.

朴煥奎,金鍾一,金鎭興,李茂錫,朴吉文,鄭洛奎,李行男,李東起 조선대학교 동력자원연구소 1984 動力資源硏究所誌 Vol.6 No.2

Separation, pressure and velocity distributions were studied fully developed two dimensinonal, incompressible flow over a flat airfoil in subsonic wind tunnel. Velocity and turbulence were measured with a two channel constant temperature hot wire anemometer and pressure with a pitot tube and pressure tranducer system. The experimental results were obtained as follow: (1) Turbulent intensity of shear layer just outside the separation point is considered to affect the size of separation bubble. (2) Static pressure coefficient is separated into three regions according to its value change. (3) Separation point is varied with the change of attack angle. (4) Velocity distributions and boundary layers normal to airfoil surface are changed as variation of attack angle of airfoil.

( Jin Seok Park ),( Hyun Jung Chung ),( Jin Woo Lee ),( Young Joo Jin ),( Byung Wook Bang ),( Seok Jeong ),( Kye Sook Kwon ),( Don Haeng Lee ),( Hyung Kil Kim ),( Yong Woon Shin ),( Young Soo Kim ) 대한간학회 2013 춘·추계 학술대회 (KASL) Vol.2013 No.1

Background/Aims: We aimed to determine the factors affecting the prevalence of hepatitis A(HAV) antibody and also tried to investigate the current prevalence of HAV antibodies in Korean their twenties. Methods: Blood samples of 298 subjects from solitary hospital in Pohang, the subjects were military soldiers in their twenties. They were assayed for anti-HAV-IgG. And economical and environmental data were obtained using a questionnaire and we performed an analysis to find affecting factors. Results: Overall anti-HAV prevalence was 24.79% in their twenties, this result had a huge change compared with the result of reports in 1970s. And also, HAV infection was associated with a variety of environmental and behavioral factors. Such as, rural resident (adjusted odds ratio [OR] = 10.7 P=0.00), presence of flies in the kitchen (OR=31.51 P=0.00), and the size of house (OR=1.002 P=0.00) were independently associated with higher prevalence of anti-HAV-IgG. And the educational pattern of father (OR=0.41 P=0.01), and hand washing after defecation (OR=0.47 P=0.00) were indepen dently associated with lower prevalence of anti-HAV-IgG. Conclusions: Even though, this study did not show the defi- nite risk factors, but we found several suspicious relating factors. Also, the differences in socioeconomic status could be considered as a risk factor for hepatitis A infection. To decrease spreading HAV, improvements in educational programs are needed.

Chung, Lana,Chung, Seo-Jin,Kim, Jin-Young,Kim, Kwang-Ok,O’Mahony, Michael,Vickers, Zata,Cha, Sung-Mi,Ishii, Rie,Baures, Katie,Kim, Haeng-Ran Elsevier 2012 Food quality and preference Vol.26 No.1

<P><B>Highlights</B></P><P>► Acceptance of Korean foods among US and Koreans were investigated. ► Stronger cultural differences were observed in the beverage than salad dressing. ► Familiarity and perceived context (traditional vs. ethnic) were both important. ► Labeling effect was relatively small compared to other factors. ► Food/flavor scales may partly predict the acceptance of Korean foods.</P> <P><B>Abstract</B></P><P>The effects of sensory and non-sensory factors on the liking of Korean style salad dressings and beverages among US subjects in two locations (California and Minnesota) and Korean subjects were investigated. Four types of dressing and five types of beverage samples were evaluated. Approximately, half of the subjects evaluated the samples under blind-labeled conditions while the other half evaluated the samples labeled with their corresponding names and flavor descriptions. The liking of each sample was rated and the reasons for liking and disliking each sample were surveyed. Various food attitudes were measured on the food neophobic scale, VARSEEK scale, and flavor attitude scales. Soy sauce & vinegar dressing was the most preferred sample among the US subjects, whereas sesame seed dressing was preferred as much as the soy sauce & vinegar dressing among Koreans. Cinnamon-ginger flavored beverage was preferred the most among the US subjects, whereas rice punch was preferred the most among Koreans. Sample labeling effect was relatively small compared to other factors. VARSEEK and food neophobia scale showed stronger effect on beverage than salad dressing. Preference attitudes for hot & spicy and roasted carbohydrate flavors affected the acceptance of salad dressing among consumers in California whereas preference attitude for garlic flavor affected the acceptance of dressing among consumers in Minnesota.</P>
