Objectives : To evaluate the pain improvement of the frozen shoulder patients taken the electro-acupuncture therapy using Visual Analogue Scale. Methods : The 38 frozen shoulder patients visited department of Acupuncture & Moxibustion in National Medical Center from 1st September 2004 to 28th February 2005 had taken the electroacupuncture therapy or body-acupuncture therapy more than 3 times.(Electroacupuncture group was 24 persons and body-acupuncture group was 14 persons.) We evaluated their improvement of shoulder pain using Visual Analog Scale(VAS) at each visit. Then we analyzed the pain improvement comparing with two groups. Results : Both VAS scores of electroacupuncture group and body-acupuncture group have significantly improved. VAS score at third visit of electroacupuncture group and body-acupuncture group have significantly improved. VAS score at third visit of electroacupuncture group was significantly lower than that of body-acupuncture group (p=0.0057). The decreased VAS score after first visit of electroacupuncture group was also significantly higher than that of body-acupuncture group(p=0.0225). Conclusion : The pain of electroacupuncture group decreased more than body-acupuncture group at early visit. But the total decreased VAS scores of two groups was not significantly different.

본 연구는 한우의 체형과 체중이 일령에 따라 어떻게 변화하며, 선발형질인 도체형질과의 상관 또한 체중 및 체형의 변화에 따라 어떠한 형태로 변화하는지 알아보기 위하여 실시하였다. 분석에 이용한 형질은 체중, 체형 및 도체형질을 포함하여 모두 17가지 형질이며 거세우 161두의 자료를 이용하였다. 성장곡선 추정은 logistic 모형을 이용하였고, 추정한 모수를 토대로 변곡일령 및 변곡일령에서의 특성을 다시 계산하였다. 각 형질에 대한 성장곡선 모수를 분석한 결과 좌골폭은 조숙성, 흉위는 만숙성 형질인 것으로 나타났다. 등지방두께에 대한 흉심, 흉폭 및 요각폭의 순위상관계수는 6~24개월까지 꾸준히 증가하는 반면 다른 체형형질들은 18개월령 이후에 감소하는 것으로 나타났다. 본 연구는 표현형 자료에 대한 분석만이 이뤄졌으나, 한우 성장 단계에 따른 유전적 변화를 살펴보기 위해 유전모수 추정과 같은 추가적인 연구가 이뤄진다면 체형형질을 한우개량에 충분히 이용이 가능할 것으로 생각된다.

The use of light weight magnesium alloy offers significant potential towards improvement of the automotive fuel efficiency. However, the application of formed magnesium alloy components in auto-body structures is restricted due to the low formability at room temperature and lack of knowledge for processing magnesium alloys at elevated temperatures. In this study, a warm tensile test of magnesium alloys was performed to measure tensile strength and elongation. An improvement in formability was confirmed at increased temperatures above about $250^{\circ}C$. Car body warm forming technology was conducted for forming forming reinforced dash components of the magnesium alloy AZ31B sheet at elevated temperatures.

Objective: The main goal of our current study was to improve the growth curve of meat animals by decreasing the birth weight while achieving a finishing weight that is the same as that before selection but at younger age. Methods: Random regression model was developed to derive various selection indices to achieve desired gains in body weight at target time points throughout the fattening process. We considered absolute and proportional gains at specific ages (in weeks) and for various stages (i.e., early, middle, late) during the fattening process. Results: The point gain index was particularly easy to use because breeders can assign a specific age (in weeks) as a time point and model either the actual weight gain desired or a scaled percentage gain in body weight. Conclusion: The point gain index we developed can achieve the desired weight gain at any given postnatal week of the growing process and is an easy-to-use and practical option for improving the growth curve.
