This study investigated the center of mass and lower extremity kinematic patterns between carved and basic paralell turn during alpine skiing. Six experienced skiers (age: $20.67{\pm}4.72yrs$, body mass: $72.67{\pm}7.15kg$, height: $171.00{\pm}5.51cm$) participated in this study. Each skier were asked to perform carved and basic paralell turn on a $22.95^{\circ}$ groomed slope. Each turn was divided into the initiation phase, steering phase 1 and 2. The results of this study show that the carved turn spent significantly less running time than basic paralell turn at all three phases (p<.05). Also vertical displacement of the center of mass was significantly greater in carved turn at all three phases, whereas inward leaning angle of the center of mass was significantly greater in carved turn at the steering phase 1 and 2 (p<.05). Bilateral knee and hip joint angle were significantly greater in basic paralell turn at the initiation phase and the steering phase 2 (p<.05). On the other hand, left knee and hip joint angle were significantly greater in basic paralell turn at the steering phase 1 (p<.05). In order to perform successful carved turn, we suggest that skiers should coordinate bilateral knee and hip joint angles to adjust the center of mass, depending on three ski turn phases.

The author surveyed overall obesity indicies and factors concerned with obesity such as dietary intake, physical activity, stress and life style with the subject of doctors. The number of subjects was total 508 with 396 men and 112 women. They were subgrouped into surgical part, medical part and service and basic part by speciality. And also subgrouped into intern and resident, pay doctor, and practitioner by working type. The results were as follows. 1) Obesity indices: BMI of total doctor was $23.1{\pm}2.8$, and WHR was $0.87{\pm}0.08$ and overweight prevalence(BMI>25.0) was 23.6%. It was within normal limit but slightly over the Korean standard. The degree of obesity indices of subgroups by speciality was 'surgical part > medical part > service and basic part', and by working type was 'practitioner > pay doctor > intern and resident'. 2) Dietary intake and Physical activity: Average dietary intake was $2148{\pm}451kcal/day$. The degree of dietary intake by speciality was 'surgical part > medical part > service and basic part'. By working type it was 'practitioner > pay doctor > intern and resident'. Average physical activity was $29{\pm}5$ METs/day. The degree of physical activity also showed similiar pattern. But there was no significant difference among each groups. 3) Comparision between over-weight and non-over-weight group: The items that showed significant difference between two groups were dietary intake, skip breakfast, regular exercise, smoking, heavy drinking, chronic disease etc.

Objectives : The purpose of this study is to evaluate the feasibility of massive clinical research and to make a basic analysis on the effectiveness and safety of moxibustion treatment on knee osteoarthritis compared to usual care. Methods and Results : This study is a protocol for a pilot randomized controlled trial. Forty participants are assigned to the moxibustion group (n=20) and usual care group (n=20). Participants assigned to the moxibustion group receive moxibustion treatment on the affected knee(s) at six standard acupuncture points (ST36, ST35, ST34, SP9, Ex-LE04 and SP10) three times per week for four weeks (total of 12 sessions). Participants in the usual care group don't receive moxibustion treatment during the study period and follow-up are made on the 5th, 9th and 13th weeks after random allocation. Both groups are allowed to use any kind of treatment, including surgery, conventional medication, physical treatment, acupuncture, herbal medicine, over-the-counter drugs and other active treatments. Education material that explains knee osteoarthritis and current management options and self-exercise is provided for each group. The pain scale of the Korean Western Ontario and McMaster Universities Questionnaire (K-WOMAC) is the primary outcome measurement used in this study. Other subscales of the K-WOMAC, the Short-Form 36 Health Survey (SF-36), Beck Depression Inventory (BDI), Physical Function test, Patient Global Assessment, and Pain Numeric Rating Scale (NRS) are used as outcome variables to evaluate the effectiveness of acupuncture. Safety is assessed at every visit. Conclusions : The result of this trial will provide a basis for the effectiveness and safety of acupuncture treatment for knee osteoarthritis.

Background: A forward head posture (FHP) is one of the most common types of poor head posture in patients with neck disorder. A prolonged FHP might increase pressure on the posterior cranio-cervical structure and exhibit reduced performance on a cranio-cervical flexion test (CCFT). CCFT is included to activate deep cervical flexor muscles and inhibit excessive activation of superficial cervical flexor muscles. Therefore, the selective activation of deep cervical flexors is needed for effective exercise for FHP. Objects: The purpose of this study was to compare muscle thickness between longus colli (Lco) and sternocleidomastoid (SCM) using ultrasonography in subjects with FHP depending on head support. Methods: This was a cross-sectional, case-control research design study. The ultrasonographic images of Lco and SCM were taken in 17 subjects with FHP during the 5 phases of the CCFT with and without a head support. Towel was used for supporting head to make the neutral head position in supine. Changes in muscle thickness during the test were calculated to infer muscle activation. Data were analyzed using repeated measures of two-way analysis of variance with the significance level of .05. Results: When subjects performed the CCFT with head support, there was a significant difference in muscle thickness of Lco and SCM (p<.05). According to a post hoc paired t-test, change of thickness of Lco was greater at all phases, and change of thickness of SCM muscle was less at phase 4 and 5 in condition with head support (p<.01) compared to condition without head support (p<.01). Conclusion: The result of this study suggest that applying head support for neutral head position during CCFT could be a useful method for activating Lco muscle without excessive activation of SCM muscle.

Background: Limitation of hamstring extensibility is often associated with various musculoskeletal problems such as alterations in posture and walking patterns. Thus, certain appropriate strategies need to be established for its management. Objects: The aim of this study was to compare the effects of the neural mobilization technique and static stretching exercises on popliteal angle and hamstring compliance in young women with short hamstring syndrome (SHS). Methods: Thirty-three women with SHS were randomly assigned to either group-1 ($n_1=17$) that underwent the neural mobilization technique or group-2 ($n_2=16$) that underwent the static stretching exercises. Outcome measures included the active popliteal angle (APA) and a hamstring's electromyographic (EMG) activity at a maximum popliteal angle of the baseline. Intervention for each group was performed for a total time of 3-min (6 sets of a 30-sec application). Results: There were significant interactions between time and group in the APA [group-1 (pre-test to post-test): $69.70{\pm}8.14^{\circ}$ to $74.14{\pm}8.07^{\circ}$ and group-2: $68.66{\pm}7.42^{\circ}$ to $70.52{\pm}7.92^{\circ}$] (F1,31=6.678, p=.015) and the EMG activity of the hamstring (group-1: $1.12{\pm}.30{\mu}N$ to $.69{\pm}.31{\mu}V$ and group-2: $1.19{\pm}.49{\mu}V$ to $1.13{\pm}.47{\mu}V$)(F1,31=6.678, p=.015). Between-group comparison revealed that the EMG activity of the hamstring was significantly different at post-test between the groups (p<.05). Furthermore, in within-group comparison, group-1 appeared to be significantly different for both variables between pre- and post-test (p<.05); however, group-2 showed significant difference in only the APA between pre- and post-test (p<.05). Conclusion: These findings suggest that the neural mobilization technique and static stretching exercises may be advantageous to improve hamstring compliance in young women with SHS, resulting in a more favorable outcome in the neural mobilization technique.

Despite the fact that it is not a fatal symptom. the lower back pain of human species is considered a health problem of modern society: 80% of world population experience it and the distress and dysfunction caused by interferes daily life as well as the general productivity. This study was performed to investigate the general tendency of lower back Pain on nurses: influence of nursing activities, working condition and the physical characteristics of nurses on the pain in order to provide data for prevention and treatment. 386 nurses working at 16 general hospitals throughout the country were sampled. Questionaries developed by the researcher was used for data gathering. Results are as follows : 1. Lower back pain was experienced by most(72.3%) of the nurses: the highest rate of -Pain experience was revealed to be the a9e group of 35-39 (80.8%) followed by 25-29 group (74.2%). 2. In almost all instances (91.4%), the first pain attack occurred before the age of 29, and in 73.1%. the attack occurred between the age of 15-24. 3. In 10.1%, the pain was almost persistent or occurred every other day frequency. In 9%, the pain was relieved by the administration of analgesics or "unable to move". 4. More than 6 days′sick leave due to the pain revealed to be in 2.2%. No significant difference was revealed between specialities of service. 5. Pain experience and the over or under weight revealed not to have significant relations. (X$^2$=0.55224, p〉0.7587) 6. The length of working hour of I. C. U. and O. R, revealed to be longer than that of nurses general ward, however. no significant difference on the rate of pain occurrence apparent. (X$^2$=0.4952, p〉0.8239) No significant difference on the rate of pain occurrence between nurses working over 46 hours/week and under 45 hours/week. (X$^2$=3.86241, p〉0.078318) 7. The most frequent Pain related movement revealed to be "lifting patient or heavy object" (24. 7%, N=68) followed by "the sameness of position, either standing or sitting"(16.8%) 8. Regular physical exercise revealed to have no significant influence on the rate of Pain occurrence. 9. Higher raft of pain experience was revealed in the group of nurses wearing eye glasses. Uncomfortable shoes revealed to have influenced the pain. 10. The most frequent pain relieving treatment revealed to be "rest" (54.2%, N= 151) followed by "analgesics" (12.6%, N=35) and "hot compress/fomentation"(10.5%, N=29). In 13.7% (N=38) no special care was given.
