Because of its more complete hydrolysis and rapid absorption, MCT is expected its usefulness in the diets of patients with malabsorption syndrom. Also, several authors reported that serum cholesterol level was lower after MCT feedings. In this study, rate of each experimental group were fed for 4weeks with 20％ MCT, 20％ corn oil, mixed diet of 10％ MCT and 10％ corn oil, mixed diet of 17％ corn oil and 3％ shortening. After experimental diet, it was measured to growth rate and serum cholesterol, triglyceride and phospholipid level. The results were as follows; 1. The body weight gain was the lowest in MCT group and others were lower than control group. 2. Serum total cholesterol level was the lowest in corn oil group and others were significantly lower than control group. Free cholesterol level was lower in all experimental groups than control group too. 3. Serum HDL-cholesterol level was significantly higher in all experimental groups than control group. 4. The ratio of VLDL, LDL-Cholesterol to HDL-Cholesterol was significantly lower in all experimental groups than control group. 5. Serum triglyceride level was higher in all experimental groups than control group. Serum phospholipid level was significantly in only mixed diet group of corn oil and shortening than control group. 6. The ratio of total cholesterol to phospholipid was significantly lower in corn oil diet group than control group.

The purpose of this study is to evaluate the performance of Housing Service Centers in terms of a new attempt made by NGOs and to then determine the implication of collaboration with lower level local governments in a housing welfare delivery system. The evaluation of the performance of the Housing Service Centers focused on three aspects: the performance outcomes for three years, comparative advantages to lower level local governments, and the vulnerability as an NGO. As a result of evaluating the outcome of Housing Service Centers and comparative advantages of Housing Service Centers to the local government, it is expected that a more effective housing welfare delivery system is able to be constructed when Housing Service Centers and lower level local governments collaborate. However, fiscal vulnerability of Housing Service Centers as NGO's will restrict the sustainability of the collaboration of both organizations. Therefore, as a conclusion, this study proposed that the governments should make use of Housing Service Centers as a public policy agency and projects should be based on a contract.

This study aimed to determine the effect of lower trapezius muscle strengthening exercises on pain, neck disability index (NDI), cervical range of motion (ROM), and lower trapezius muscle strength in patients with unilateral neck pain. Following baseline measurements, the subjects (N=40) with unilateral neck pain were randomized into one of two 5 weeks exercise intervention groups: a experimental group (EG, $n_1=20$) that received strength training of the lower trapezius muscles or a control group (CG, $n_2=20$) that received routine physical therapy program. Each group participated in the intervention for 30 minutes, 3 times a week, for 5 weeks. All participants performed 2 repetitions of each intervention per day. The numeric pain rating scale for pain, NDI, ROM, and lower trapezius strength were recorded both pre- and post-intervention for both groups. Paired t-tests were used to determine significant changes post-intervention compared with pre-intervention and independent t-tests were used to analyze differences in the dependent variables between the 2 groups. After the 5-weeks intervention, both groups experienced significantly decreased pain and disability level (p<.05) and significantly increased cervical flexion, extension, lateral flexion, and rotation ROM (p<.05). The EG that received strength training of the lower trapezius muscles showed greater improvements in pain and functional disability level, cervical rotation, and lower trapezius strength than the CG (p<.05). These results suggest that a lower trapezius strengthening exercises reduce neck pain and neck disability level and enhance cervical ROM and lower trapezius strength level in patients with unilateral neck pain.

The purposes of this study were to analyze factors of mass customization for hair salon's customers and to identify the differences among groups segmented by mass customization level. The self-administered questionnaire was used for data collection. The respondents were 423 women using hair salons. Factors of hair salon's mass customization implementation were sanitary condition & hair salon's staff, hair styling technique, communication service, tangible service, monetary support, convenience service, and visible service. Hair salon's customers were categorized into the high-level of needs group, the middle-level of needs group, and the low-level of needs group. The high-level of needs group consisted of university students or women with a higher education or higher income. This group selected beauty salons by the promotion or advertisements, preferred their own unique hair style or a little-fashionable hair style, and showed a lower level of patronage. The middle-level of needs group consisted of university students or women with a higher education or higher incomes. They selected hair salons by service prices, preferred a basic hair style, and showed a midium level of patronage. The low-level of needs group consisted of women with lower education or lower income. They selected beauty salons by career of hair dressers or the promotion or advertisement, preferred highly fashionable hair style, and showed high level of patronage.

The author compared indices of thyroid function in 76 patients with panic attack and 80 control subjects. And SCL-90-R was performed to evaluate the relationship between the psychiatric symptoms and thyroid indices in the patients with panic attack The results were as follows: 1). No siginificant differences in T3, T4 or TSH were found between the two groups. But T3 level was significantly lower in male panic patients than male controls(p<0.005). 2) The T3 level was significantly lower in male panic patients who had higher depression socre than average in SCL-90-R(p<0.025). 3) The TSH level was significantly lower in patients with higher anxiety(p<0.001) and phobia(p<0.05) score and in female panic patients(p<0.001) with higher anxiety and phobia score than average in SCL-90-R. 4) The phobic symptom(p<0.001) was siginificantly higher and the T3 level(p<0.005) was lower in the male than the female patients with panic attack.

The purpose of this study was to analyze the muscle fatigue for lower limbs during the level and downhill running. The subjects were 6 males of twenties who have no experience to get the injury in the lower limbs and required to run on the level and downhill which was -7% grade treadmill at 8.3km/h. EMG signal was gained by ME3000P8 Measurement Unit and computed the Median Frequency(MF) with the power spectrum analysis in the Megawin software. Rectus femoris(RF), Vastus lateralis(VL), Gluteus medius(GLU), Biceps Femoris(BF), gastrocnemius medial head(GM), gastrocnemius lateral head(GL), Tibialis anterior(TA) were selected. The result of this study were as follows: The MF of RF decreased in the downhill running than level running in length of time but, the MF of VL was opposite. The MF of BF decreased in the level and downhill running, but, the MF of BF decreased much in the level than downhill running. The MF of GLU decreased much in the downhill running but, almost no change in the level running. The MF of TA decreased in the level running than downhill running. The MF of GL decreased in the level running but, the MF of GM decreased in the downhill running in length of time. This study analyzed the muscle fatigue of the lower limbs with the median frequency on the basis of an assumption that the impact force for the flexion and extension of the joint and the body mass may be much in the eccentric contraction such as the downhill running than level running. RF and GM showed the muscle fatigue in the downhill running than level running. BF and GL showed the muscle fatigue in the level running than downhill running.

The purpose of this study was to estimate the mineral intakes and serum mineral levels of pregnant and lactating women. The subjects consisted of 34 non-pregnant, 56 pregnant and 20 lactating women. Nutrients intakes were investigated by the 24-hr recall method, and serum major and trace minerals were analyzed by the ICP-spectrometry. Calcium (Ca) and zinc (Zn) intakes were observed lower than RDA especially for both pregnant and lactating women. Iron (Fe) intake of pregnant women was $85 - 139\%$ RDA through Fe supplementation, and that of lactating women was lower than RDA. Compared with non-pregnant women, the pregnant women had similar Ca intake and higher magnesium (Mg) intake. Comparing with the non-pregnant women, serum Ca level in pregnancy was lower, and that of lactating women was not significantly different. Serum phosphorus and Mg levels were not significantly different among the groups. Serum Fe level of pregnant and lactating women was lower than that of the non-pregnant women. Serum Zn level of pregnant women was lower than those in the lactating and non-pregnant women. Serum copper level decreased as the pregnancy progressed. Serum sodium (Na) level was higher in 2nd- and 3rd trimester and potassium (K) level was higher in 3rd trimester and lactating period than other groups. Na/K ratio was not significantly different among the groups. During all periods, there was no correlation between dietary intakes and serum levels in each minerals. Serum Ca level positively corrleated with serum Mg level, especially in 3rd trimester and lactating women. In general, serum mineral levels in pregnancy were changed compared to the levels in non-pregnancy and restored in lactation to the levels for non-pregnancy.

The purpose of this study was to examine the effects of adolescents' school adjustment on depression in their transitional period and to find the moderating effects of parental support, parental monitoring, and peer support on the relationship between school adjustment and depression. The participants were 550 first graders in three middle schools in Incheon Metropolitan City and Kyung-gi Province. The major findings of this study were as follows: First, adolescents' school adjustment had significant effects on depression. The lower the level of school adjustment was, the higher the level of depression was. Second, parental support, parental monitoring, and peer support had moderating effects on the relationship between school adjustment and depression. Parental support decreased the depression of adolescents who were at a lower level of adjustment to peer relationship or school class. Parental monitoring decreased the depression of adolescents who were at a lower level of adjustment to school adjustment. On the contrary, parental monitoring increased the depression of adolescents who were at a higher level of adjustment to school adjustment. Peer support decreased the depression of adolescents who were at a lower level of adjustment to school class.
