Objective: We have various ways in evaluating the level of low back pain as sequelae, general approaches such as neurologic examination, MRI, Radiologic examination and evaluating the effect of psychological stress on the low back pain. Besides We can find another approach to evaluating the sequale of low back pain in TA patients. So, I intend to analyze how much relationship the patients that got low back pain by TA have with Roland Morris Disability Scale(RMS) in 2 months after discharge. Methods: In this article, I will compare two results of TA inpatients and non-TA inpatients, which obtained with the RMS. This study was carried out about 22 TA patients and 18 non-TA patients, who had low back pain and were hospitalized between March 2002 and July 2002. Results & conclusions : 1. RMS point is related with the post-discharge term to a point of time of answering the questionnaire in both TA patients and non-TA patients. 2. In distribution of RMS point, Gr II take most possesion as 41% in TA patients while Gr I take most possesion as 56% in non-TA patients. 3. In distribution of RMS point, patients that correspond to more than Gr III take 27% in TA patients, 16% in non-TA patients. 4. TA patients show higher level of distribution than non-TA patients in RMS point in verifying them by mean value and T-test. 5. Degree of pain score change(${\Delta}$P.S), using mean value and T-test, showed lower level of distribution in TA patients than non-TA patients. 6. We can see that TA patients have more restriction in their life for low back pain.

The objective of this study was to determine the effect of drinking water containing trimethyl glycine or ascorbic acid on growth performance and blood parameter profiles of duck exposed to scorching heat stress. A total of 480 ducks were randomly assigned to the following eight experiment groups for 42 days : control group C with general water, treatment group 1 (T1) with drinking water containing 100 ppm ascorbic acid, treatment group 2 (T2) with drinking water containing 200 ppm ascorbic acid, treatment group 3 (T3) with drinking water containing 300 ppm ascorbic acid, treatment group 4 (T4) with drinking water containing 400 ppm trimethyl glycine, treatment group 5 (T5) with drinking water containing 800 ppm trimethyl glycine, treatment group 6 (T6) with drinking water containing 1,200 ppm trimethyl glycine, treatment group 7 (T7) with electrolytes of KCl (0.5%) + $NaHCO_3$ (1.0%)+NaCl (0.5%). Our results revealed that the body weights and feed intakes of treatment groups, especially T3 and T6, were increased compared to the control group, where as the feed conversion ratios of treatment groups were decreased (p<0.05). Blood levels of total cholesterol, triglyceride, LDL-C, glucose, AST, ALT and pH in treatment groups were lower compared to those in the control group (p<0.05). Blood levels of red blood cell, platelets profiles, electrolyte and gas in treatment groups were higher compared to those of the control group (p<0.05).

This review provides an overview of dietary nucleotides as an alternative to in-feed antibiotics for weaning pigs. Dietary nucleotides are composed of DNA or RNA molecules and are normally contained in protein-rich feed ingredient, brewer's yeast, yeast extract, and milk. Weaning pigs are suffering from several stresses, such as environmental challenges (i.e. crowding, transportation, and feeding). Such stressors can damage the intestinal epithelium and cause an invasion by Escherichia coli, secondary inflammatory responses, and post weaning diarrhea. To overcome weaning disorder, people often use antibiotics which reduce symptoms and boost growth performance. However, since antibiotics were banned due to concerns of antibiotic resistant bacteria, researchers are studying alternative materials to antibiotics. Dietary nucleotides are one of the alternative materials for replacing antibiotics and can be used in abnormal conditions, such as weaning diarrhea, low digestibility, and disease condition. Nucleotides have substances that have important roles in cell division and cell growth, affecting growth performance, intestinal condition, and immunological effect at the weaning stage. However, nucleotides' composition is very different between sources and this aspect makes it difficult to utilize nucleotides at the weaning stage. Therefore, this review paper focuses on i) the characteristics and functions of dietary nucleotides and ii) the effect of dietary nucleotides on the growth performance and immune system of pigs.

Objectives: This study was aimed to figure out the effect of Onkyung-tang (OKT) on cold hypersensitivity on feet in female patients. Methods: This study was designed to implement multi-center randomized clinical trial in three korean medical hospitals. The female patients who were enrolled in this study were 112 women who suffered from cold hypersensitivity on feet. They were randomly allocated into OKT group or control group in 1:1 ratio. The primary outcome was change in score of visual analogue scale of hypersensitivity on feet, and the secondary outcomes were thermometer of LU4, PC8, ST32, LR3, visual analogue scale of hypersensitivity on hands, result of cold stress test, and score of World Health Organization Quality of Life-BREF. Results: In both group, the VAS of hypersensitivity on feet and hands was decreased while taking the medicine, and the effect of decreasing the VAS continues for the 4 weeks after the end of medication (p<0.001, 0.003, 0.001). In OKT group, the body temperature difference in lower extremity (ST32-LR3) was steadily decreased at every visit and it was statistically significant(p=0.003, <0.001). On the other hand, in control group, the body temperature difference in lower extremity was decreased only while taking the medicine (p<0.001). Conclusions: OKT significantly reduced discomfort coldness on feet in patients, and the effect of treatment was maintained at least for four weeks after medication.

리쿠퍼레이터 사이클을 적용하는 경우 단순사이클에 비하여 이론적으로 상당한 효율 증가를 가져올 수 있는 것으로 알려져 있으나 기기 내부의 압력손실, 열응력, 지나친 무게 증가 불리한 요소도 많이 있다. 그러므로 리쿠퍼레이터를 발전용 가스터빈에 적용하고자 하는 경우 리쿠퍼레이터가 가지는 여러 장단점을 고려하여 전체 수명 기간 중 경제적 타당성 측면에서 신중히 검토되어 져야 할 것으로 판단된다. 아직까지 산업 분야에서는 $20\sim300kW$급까지의 마이크로 터빈에서만 리쿠퍼레이터가 적용되고 있으며 그 이상 급의 가스터빈의 경우 지난 $40\sim60년대$ 해군에 잠시 시도된 외에 발전용으로는 거의 적용된 바가 없다. 본 논문에서는 이러한 발전용 리쿠퍼레이터 사이클의 적용성을 압력 손실, 부분부하 제어 등의 측면에서 검토하였다.

Cerebral ischemia results from a transient or permanent reduction in cerebral blood flow that decreases oxygen and glucose supply. When the cellular oxygen supply is reduced to critical level, damage to cells and induction of cell death are occurred by excitotoxicity, oxidative stress and inflammation. Ischemia remains one of the leading causes of death, but there is no effective treatment that might protect neurons gainst ischemia by interrupting the cascade of cell death. In this study, human neuroblastoma SH-SY5Y cells are exposed to oxygen and glucose deprivation (OGD) followed by reoxgenation. OGD can mimic the acute restriction of metabolite and oxygen supply caused by ischemia and is widely used as a model of ischemic conditions. SH-SY5Y cells are treated samples at the commencement of OGD to achieve different final concentrations, and cell viabilities were quantified using the measurement of flow cytometry analysis. Of those tested, the extracts of Polygala tenuifolia (roots), Dictamnus dasycarpus (barks), Polygala tenuifolia (roots), Eucommia ulmoides (branches), Eucommia ulmoides (barks), Poria cocos (whole), Sophora flavescens (roots) showed neuroprotective effects, with $EC_{50}$ values of $4.5{\pm}0.6$, $7.9{\pm}1.5$, $10.5{\pm}0.7$, $18.4{\pm}1.9$, $19.6{\pm}0.3$, $21.6{\pm}1.9$, and $30.7{\pm}3.9{\mu}g/m{\ell}$, respectively.

The purpose of this study is first to examine the tendency in what kinds of activities are carried out as family rituals; what kinds of obstacles there are; and why any problems, if any, tend to arise. Second, the study seeks to discern the relationship between family rituals and wives' marital satisfaction. For this purpose, the study surveyed 251 wives who had fourth, fifth, or sixth grade children and resided in Busan, and then analyzed the data obtained from the survey. The major findings of this study can be summarized as follows: (1) Regarding the dinner ritual, it turned out that a majority of subjects had a difficult time establishing a regular ritual due to 'their busy schedule at work' and 'children's studying at academies'. For the weekend leisure ritual, in the case of difficulty in spending this kind of time it tended to be because of the wives' 'busy schedules at work' and 'lack of mutually available time for all family members'. In birthday rituals, when wives reported having trouble with her family members regarding birthdays, they explained that this was most often' because family members forget their birthday'. Finally, when the subjects reported problems related to tradition rituals, it was mainly because of 'stress from the burden of housework (2) In every dimensions including occurrence, routine, deliberateness, attendance, affect, and symbolic significance, the top-ranked group showed a high degree of satisfaction in their marriage.
