Purpose: This study was conducted to examine the effects of solution-focused group counseling on the general stress, stress response and coping in the delinquent juveniles. Method: The subjects consisted of a convenience samlple of 60 delinquent juveniles who had been placed under probation in Kwang-ju, and recruited from Oct., 2000 to Dec., 2000. Solution-focused group counseling was conducted for the experimental group once a week for 120 to 180 minutes for 6 week. The control group received no group session. For both groups the level of general stress, stress response and coping were measured before and after the experiment. Result: General stress significantly decreased in the experimental group and increased in the control group, but showed no significant difference between the two groups. Stress response decreased significantly in the experimental group and increased in the control group, but showed no significant difference between the two groups. The problem-focused coping significantly increased in the experimental group and decreased in the control group, and showed a significant difference between the two groups. The emotion-focused coping significantly decreased in the experimental group and increased in the control group, and showed no significant difference between the two groups. Conclusion: This study showed that solution-focused group-counselling has a positive effect on variables like the general stress, stress response, emotion-focused coping and problem-focused coping. Further study needs to be conducted to verify results.

Purpose: Among patients with multiple traumatic fractures, a tendency to form more callus exists in groups with multiple fractures combined with traumatic brain injury. This retrospective study evaluated the hematologic factors that might be useful to predict callus formation by comparing serologic tests and clinical and radiologic results in two groups. Methods: From January 2000 to December 2010, patients with femur shaft fractures were divided in two groups: one without traumatic brain injury (control group: 32 cases), and the other with traumatic brain injury (study group: 44 cases). We evaluated routine serologic exams and the amount of callus formation during the follow-up period. Results: Only the alkaline phosphatase level was statistically different between the two groups, not the White blood cell count, C-reactive protein, total calcium, and lactate dehydrogenase level. The amount of callus formation on the antero-posterior radiograph at the last follow up period was 74.9% in the study group and 42.1% in the control group. Then lateral radiograph showed 73.2% callus formation rate in the study group and 31.8% in the control group. Conclusion: In routine serologic exams, the two groups had no significant differences, except for the alkaline phosphatase level. The group with traumatic brain injury had much more callus formation, but there was no reliable factor to predict callus formation on the routine serologic exam.

Purpose: This study examined the effects of local vibration using a massage gun on the triceps surae flexibility by measuring the ankle dorsiflexion range of motion (ROM) compared to static stretching in healthy adults. Methods: Twenty healthy subjects were instructed in this study. They were allocated randomly to two groups: local vibration (LV) and static stretching (SS). The ankle dorsiflexion ROM was measured before and after the intervention in supine (open kinetic chain, OKC) and standing (closed kinetic chain, CKC). The LV group received local vibration using a massage gun for five minutes on their triceps surae, and the SS group stood on the Q board with a dorsiflexed ankle for five minutes. The ROM between pre- and post-intervention and the change in ROM between two groups were analyzed. A paired t-test was used to compare the ROM between pre- and post-intervention, while an independent t-test was used to compare the change in ROM between the two groups. Results: Both groups showed a significant difference between pre- and post-intervention in the position of both the OKC and CKC. The change in ROM, however, was not significantly different between the two groups. Conclusion: The application of local vibration using a massage gun for five minutes on the triceps surae could improve its flexibility as much as the application of static stretching. A massage gun for the application of a local vibration stimulus may be effective, simple, portable, and comfortable.

Differential item functioning (DIF) based on Rasch model can be used to examine whether the items function similarly across different groups and identify items that appear to be too easy or difficult after controlling for the ability levels of the compared groups. The Oswestry low back pain disability (Oswestry) has traditionally been proved as an effective instrument measuring disability resulting from low back pain (LBP). In this study, DIF method was used to explore whether items on the Oswestry perform similarly across two different groups (participants with LBP and no LBP). A series of Rasch analyses on the 10 items of the Oswestry were performed using Winsteps$^{(R)}$ software. Forty-two participants with back pain were recruited from 3 rehabilitation hospitals in Gainesville, Florida. Another 42 participants with no LBP were recruited from several public places in the rehabilitation hospitals. Based on the DIF analysis across the two groups, several items were found to have an uniform DIF. Participants with no LBP had more difficulty on lifting and personal care items and participants with LBP had more difficulty on sleeping and social life items. For non-LBP group, a high ceiling effects (83% of participants with non-LBP) was detected, which was not be able to be effectively measured with the Oswestry items. Although 4 items of the Oswestry function differently across the two groups, all items of the Oswestry were well targeted the LBP group.

The purpose of this study was to investigate lower-limb joint torque of the two groups as it changed by somatosensory stimulation during the descent down three stairs of different heights and to describe the difference between the two groups, which are young people group and elderly people group. Subjects of each groups climbed down a stair at four stimulation conditions, which are non-stimulation, tibialis anterior tendon stimulation, achilles tendon stimulation, tibialis anterior - achilles tendon stimulation. Motion capture data were collected using 3D optoelectric motion tracking system that utilizes active infrared LEDs, near infrared sensor and force plate. The obtained motion capture data was used to build 3D computer simulation model. The results show that lower-limb joint torque of the two groups changed with somatosensory stimulation as they descended the stairs and the joint torque of the two groups differed from each other.

PURPOSE: This study examined the effective impact of self and resistive and ultrasound-biofeedback diaphragm breathing on the pulmonary function and diaphragm thickening ratio of young adults. METHODS: Thirty normal adults were assigned randomly to three experimental groups (self- diaphragm breathing (n=9), resistive-diaphragm breathing (n=11), ultrasound-biofeedback diaphragm breathing (n=10)). Each group participated for 15 minutes for times with a two minute rest between two sets. The subjects were assessed using the pre- and post- diaphragm thickening ratio and the pulmonary function (forced vital capacity, forced expiratory volume at one second, maximal voluntary ventilation, and respiratory rate) on the thirty subjects. A paired t-test was to determine the difference between before and after the experiment in each group of diaphragm breathing before and after the exercises. One-way ANOVA was used to determine the differences between the groups. RESULTS: The forced vital capacity and maximal voluntary ventilation measurements revealed a significant difference in the resistive-diaphragm breathing group than the other two groups. On the other hand, there was no significant difference between the self-diaphragm breathing and ultrasound-biofeedback breathing groups. CONCLUSION: The resistive-diaphragm breathing group showed greater improvement in the pulmonary function than the other two groups. Therefore, resistive-diaphragm breathing will improve the pulmonary function on normal young adults.

When segmenting consumers according to their fashion adoption behavior, it has been assumed that consumers' fashion conformity and innovativeness characteritics are negatively correlated. The purpose of this study was to examine the relationship between conformity and innovativeness and that these two attributes exist independently. The research problems of this study were to segment consumers according to the degrees of conformity and innovativeness, and to identify differences in reference groups and clothing purchasing behavior among the segments. The results of the empirical study showed that the fashion conformity and innovativeness were in and innovativeness; High conformity/High innovativeness group(HC/HI), High conformity/Low innovativeness group (HC/LI), Low conformity/High innovativeness group(LC/HI?, and Low conformity/Low innovativeness group (LC/LI). When the groups were compared in their reference groups and purchasing behavior, it was found out that HC groups were more influenced by reference groups than LC groups. When HC/LI and HC/HI groups were compared, HC/LI group was more influenced by their parents and siblings, while HC/HI group was more influenced by upper class and celebrities. Both groups were mostly influenced by friends and desirable passengers on the street. Friends and passengers were most influential to LC groups also, even though they were less influenced than HC groups. In conclusion, the fashion conformity and innovativeness were found to exist in different dimensions consisting dual structure. Thus, retailers and marketers can make their strategies more successfully if they use these two characteristics separately when segmenting consumers.

This study examines the high school girls in Inchon area dividing them into three groups according to their weight, the low-weight group, the normal weight group and the overweight group to find out their food habit and food preference. The result reveals that more students from the low-weight group have breakfast regularly than those from the other two groups, and more students from the low-weight and normal weight groups always have lunch. However, none of the students from those three groups skip their suppers. This study also shows that there are more students from the overweight group having snacks, and more students from the low-weight have the unbalanced diet problem than those from the other two groups. Next, this study examines their attitude toward breakfast. It seems that all the students from three different groups similarly regard breakfast as a very important meal. Additionally in deciding what to eat, the taste of food is considered as the most important factor for them all. In their preference of food taste, there seems to be a slight difference. The students from the low-weight and normal weight groups prefer hot food to sweet food, but those from the overweight group prefer sweet food to hot food. Also in food preference the difference among the groups is that the students from the low-weight and normal groups prefer favorite food and snacks. While those from the overweight groups prefer cereals and noodles.

The purpose of this study was to investigate the effect of protein and dietary fiber levels on the activities of ehanol metabilizing enzymes of the brain in acute and chronic ethanol-treated rats. Male Sprague-Dwley rats were fed on diets containing two levels of protein(7%, 20%)) with two levels of fiber(5%, 105) for 5 weeks. Rats were orally administered 40% (v/v) ethanol(5g/body weight) 90 min before decapitation in the acute ethanol-treated groups and 25% (v/v) ethanol (5g/kg body weight) once a day for 5 weeks in the chronic ethnol-treated groups. Cytosilic alcohol dehydrogenase (ADH) activities were higher than those of mitochondrial ADH. The ADH activities were increased by 20% protein and %% fiber levels in the diet in two fractions , but were decreased by chronic ethanol treatment. Mitochondrial aldehyde dehydrogenase (ALDH) activities did not change by ethanol treatment but were increased by the 20% protein level. However, cytosilic ALDH activities were decreased by chronic ethanol treatment at the 5% fiber level and did not change with protein levels. Both ALDH activities were higher in the 10% fiber groups than the 5% fiber groups. Cytochrome P-450 contents were significantly increased in the chronic ethanol-treated groups but xanthine oxidase (XO) activities did not change. P-450 contents and XO activities were significantly decreased in both the low protein and fiber groups.
