The effect of mixed onion pills on body composition, blood pressure, and concentrations of blood glucose and lipids were studied in 10 men ($38.11{\pm}2.82$ years old). The mixed onion pills was produced by mixing quercetin, onion, mulberry leaves and buckwheat. Ten volunteers (male, BMI 23.0~35.4 kg/$m^2$) were chosen for this study. The volunteers consumed 1.2 g of mixed onion pills (containing about 30 mg of quercetin) per day for 2 months. The administration of the mixed onion pills did not produce any weight and BMI changes in the subjects. The systolic blood pressure and the level of blood glucose were slightly lowered by the supplementation of the mixed onion pills. After 2 months both the concentration of plasma triglycerides and total cholesterol of the subjects were lowered by 12.4% and 5.0%, respectively (triglyceride; pre $251.67{\pm}45.63$ mg/dL vs. post $220.44{\pm}44.67$ mg/dL and total cholesterol; pre $207.25{\pm}10.39$ mg/dL vs. post $196.63{\pm}10.47$ mg/dL, p<0.05). These results suggest that the mixed onion pills may possibly lower the level of plasma lipids in overweight or obese men (BMI greater than 23 kg/$m^2$).

Objective: The purpose of this studyaimed to investigate the effects of scapular stabilization training using the different exercise prop for impingement syndrome of factory workers. Design: A randomized controlled trial Methods: Twenty shoulder impingement syndrome subjects were randomly divided into two groups of ten subjects each. Inclusion criteria was presence of positive sign in at least two of Neer test, Hawkins test, Yocum test, Jobe test and Speeds test. Andexclusion criteria, those with surgical history of rotator cuff, those with disease in upper limb other than shoulder impingement syndrome, those who took anti-inflammatory drugs over the past 12 months were excluded from the sample. One group was performed scapula stabilization exercise using elastic bands, while dumbbell group performed the exercise using dumbbell. Both groups performed the exercise after applying the general physical therapy. After applying five days a week for a total of six weeks, range of motion of shoulder joint, muscle strength and pain and function level were evaluated. Results: After the intervention, in both groups, all dependent variables at the 6-week post-test significantly improved compared with the pre-test (p<0.05). In addition, elastic band exercise group showed a significant differences in SPADI function score and SPADI total score compared to the dumbbell group(p<0.05). Conclusions: The elastic band training may be effective methodology using low-to-moderate intensity resistance for SPADI scores.

Purpose: The purpose of this study was to explore the effects of the 8-weeks back pain management program (consisted of exercise and education for back pain) in patients with chronic low back pain. Methods: A total of 20 subjects who visited the pain clinic in a university hospital were randomly assigned either to a experimental or a control group. Ten subjects in the experimental group carried out the back pain management program for 8 weeks, and 10 in the control group did not. Results: After the back pain management program, back pain and disability were significantly reduced, and back pain management behavior and back muscle strength were significantly increased in the experimental group. However, radiating pain and flexibility were not significantly changed after the back pain management program. Conclusion: Findings of this study indicated that the 8-weeks back pain management program had favorable effects on back pain, degree of disability, back pain management behavior, and back muscle strength in patients with chronic low back pain. Future research needs to examine the optimal intensity and frequency of back muscle strengthen exercise, and the lasting effects of education for back pain.

The soluble transferrin receptor(TfR) in human serum has been shown recently to be a truncated form of intact membrane bound receptor containing most of the extracellular domain. We purfied the transferin-free TfR from human serum by immounoaffinity chromatography which produced the single protein identity in high resolution gel chormatography. The monoclonal antibodies(MAb) against purifed serum TfR were produced by fusion of spleen cells o fimmunized Balb/c mice and SP2 cells. Ten hybrids producing MAb specific for serum TfR were identifed and determine their iostypes. A immunoraddiometric assay (IRMA) for serum TfR was established using two monoclonal IgG1 antibodies as the coating and indicator antibodies on the bosis of their suitability in sandwich IRMA of serum TfR. The mean serum TfR levels in the 15 normal male, 15 normal female, and 19 iron-deficient subjects were 5.4$\pm$0.98, 4.6$\pm$0/76, and 18.0$\pm$12.8mg/1, respectively, and the difference in mean values between normal and iron deficient subjects was significant(p=0.0005). There existed the inverse logarithmic relationship(r=-0.9336, p<0.0001) between the serum TfR and ferritin levels.

Living culture, which is a pattern of peoples' everyday living, is influenced by the socio-economic conditions as well as ideology of the society. South and North Korean societies have been segregated during the past 50 years with different socio-economic conditions and idelogies, resultsing different living cultures, even though those two societies share the same traditional culture. This project was developed to identify the differences in living cultures between South and North Korean societies, and to make suggestions for their successful integration. The second part of the project was concentrated on finding out the current living culture of North Korean families. Based on indepth interview with ten people who escaped from North Korea after 1990, empirical survey with 158 subjects was conducted. The subjects with various demographic backgrounds were asked about lifestyles concerning family living, child rearing, consumption, time management that they experienced when they were in North Korea. This study revealed differences in many aspects of living cultures of South and North Korea, and relationships were suggested in four lifestyles. This study was intended to provide ground for more information to the following study that will explore the cue of integration between South and North Korean societies in living culture.

The purpose of this study was to investigate the effects of Sea Dong-Il's technique on voice quality in patients with vocal nodules and phonasthenia (vocal fatigue). Ten patients (4 nodules and 6 vocal fatigue) participated in the study. Each subject was assessed acoustically (Fo, Jitter, Shimmer, NNE) in the first and last session. Dr. Speech (version 3.4, Tiger-DRS) was used to compare acoustic parameters of pre-and post-treatment. Sea Dong-Il's technique consisted of breathing exercise, relaxation exercise, and phonation exercise. The results were as follows: First, Sea Dong- Il's technique tended to be effective on improving voice quality in patients with phonasthenia and vocal nodules. Second, the nature of improvements were as follows: there was a significant difference between pre-and post-treatment in shimmer (p < .01) and NNE (p < .001), while there was no significant difference between pre-and post-treatment in Fo and Jitter. Finally, given the fact that the number of subjects was only 10, the jitter might have shown a significant difference if more subjects participated in the experiment.

This study was performed to determine the voluntary range of joint mobility for middle-aged Korean adults. One hundred and eighty-eight subjects(99 males and 89 females) at the age range of 40 to 60 participated for this study. Thirty body movements at various joints were conducted to measure the range of joint mobility. Subjects were grouped by Rohrer's into four based on 25th percentile. The data were analyzed to see the differences of range of joint mobility between sexes and Rohrer's index groups. The results of this study and previous studies were compared to see the differences of range of joint mobility due to the aging. Results of this study indicate that females are generally more flexible than males. Significant differences were found to exist in fourteen movement between sexes and in ten movements, females have larger range of joint mobility than males. There were no significant differences in range of joint mobility may have a tendency to decrease with ages. The results of this study provide important information in dynamic dimensions for middle-aged Korean and can be used to design the various and work places for the middle-aged.

Ten college women were divided into 5 groups and treated in randomized block design for 5 weeks with 1 interval between treatments and subjects serving as their own controls. The experimental diets were corn oil diet as a source of n-6 linoleic acid, perilla oil diet as a source of n-3 $\alpha$-linolenic acid, and fish oil diet as a source of n-3 EPA and DHA. Dietary fat was supplied at 30% Cal and modified to give the total amount of saturated fatty acids and monoenoic acids at constant level. There was no significant effect on serum cholesterol level by different PUFA. However, on a gram-for-gram basis, there was a trend that the decrease in serum cholesterol was proportionate to the degree of fat unsaturation. On the other hand, only fish oil diet significantly decreased TG level but no significant effect on the relative proportion of TG in VLDL. The degree of hypotriglyceridemia did not corrleate with the degree of unsaturation. The relative proportion of CE in LDL was reduced by all PUFA diets but significant only by perilla oil diet. The relative amount of apoprotein in LDL was significantly reduced by n-3 PUFA. HDL-Chol content was significantly increased only in fish oil diet but no change in the relative proportion of its chemical components of HDL.

Purpose: To determine the motor cortex dysfunction in hemiparetic patients due to deep intracerebral hematoma, authors performed proton magnetic resonance spectroscopy (lH MRS) for the evaluation of biochemical changes in the cortex on affected hemisphere according to axonal injury at the level of internal capsule. Methods: Ten control subjects and 14 patients with documentable hemiparesis of varying severity hemiparesis were included. All the hemiparesis was caused by deep intracerebral hematoma (putaminal and thalamic hemorrhage). In vivo 1H MRS study was performed on a 3T MRI/MRS system using STEAM sequence. As a single-voxel technique, Spectral parameters were: 20 ms TE, 2000 ms TR, 128 averages, 2500 Hz spectral width, and 2048 data points. Results: We found that the mean N-acetylaspartate (NAA)/phosphocreatine (Cr) and NAA/choline (Cho) ratios were significantly decreased in the motor cortex of the hemiparesis patients compared with control subjects. Conclusions: 1H MRS examinations of the motor cortex might help to differentiate distinct clinical entities of hemiparesis and to monitor pharmacological effects in therapeutic trials, providing a quantitative biological marker for motor neuron dysfunction. Acknowledgement: This study was supported by a grant of the Center for Functional and Metabolic Imaging Technology, Ministry of Health & Welfare, Republic of Korea. (02-PJ3-PG6-EV07-000).

We investigated the effects of trunk twist on postural stability during manually handling flat ties. Ten male subjects participated in this study. While handling 5kgf and 10kgf bundles of flat ties respectively, their centers of pressure (COPs) were measured under two levels of body position (twisted and fixed), two levels of direction (left and right), and three levels of object position ($30^{\circ}$, $45^{\circ}$, and $60^{\circ}$). Subjects' postural stability was quantified by calculating the sway length. Results showed that the effect of different object position was significant on postural sway length in subject's medio-lateral axis. Post-hoc multiple comparions revealed that, under the 5kgf load condition, the sway length was increased significantly as the object position increased to $45^{\circ}$. Under the 10kgf load condition, however, the sway length was increased significantly at the object position of $60^{\circ}$. Actual or potential applications of this research include guidelines for the design of working posture evaluation techniques.
