  • This study was intended to investigate the effect on the human body such as subcutaneous fat thickness the circumference of extremities etc. of the clothing training of putting on thin clothes periodically from the cold period. The subjects were divided into the clothing training group and the non-training group, The training group was asked to wear cool clothes in daily life and to wear the training clothes of T-shirts with half-length sleeves and pants and perform the clothing training for two hours daily three times a week in a cold environment over the period from November to February. The non-training group was asked to lead a life wearing comfortable clothes. Then a comparative experiment was conducted at 15$\pm$1$^{\circ}C$, 50$\pm$5% R, H and 0.25m/sec before and after the clothing training. After the clothing training regardless of gender subcutaneous fat thickness was more increased and total clothing weight per the surface area of the body was decreased in the training group than the non-training group. The training group showed lower skin temperature in the limbs and lower average skin temperature than the non-training group irrespective of gender which proved the effect of the clothing training. The training group was shown to have attendancy toward a greater sense of warmth and a less sense of discomfort which proved the effect of the clothing training.

  • The aim of this study was to investigate the effect of resistance training with and without whole-body vibration(WBV) on the biomechanical properties of the plantarflexor in the elderly women (>60 yrs., n=35). Thirty-five volunteers were randomly assigned to a resistance training with WBV group (RVT, n=14), a resistance training without WBV (RT, n=11), and a non-training control group (CON, n=10). The RVT and the RT groups participated in the training sessions three times a week for 8 weeks, followed by a 4-week detraining period. The CON group was instructed to refrain from any type of resistance training. To assess strength and activation of the plantarflexor muscles, maximum isometric ankle plantarflexion torque and muscle activation of the triceps surae muscles were measured using dynamometry, twitch interpolation technique and electromyography at four different ankle joint angles. Also, the lower extremity function was assessed by vertical jumping. The measurements were performed prior to, 2 and 8 weeks after the training and after a 4-week detraining period. Following the 8-week training sessions, an increase in the isometric plantarflexion strength was found to be greater for the RVT compared with the RT group (p<.05). Muscle inhibition was significantly decreased after training than before training only for the RVT (p<.05). Following the detraining period, a decrease in isometric plantarflexors strength and a increases in muscle inhibition were significantly less in the RVT compared with the RT group. In conclusion, the exercise with WBV is a feasible training modality for the elderly and seems to have a boosting effect when used with conventional resistance training.

  • The purpose of this study was to identify the superior exercise on the reduction of low back pain, between the Mckenzie exercise and the williams exercise. 24 chronic low back pain patients were randomly divided into 3 groups (Mckenzie exercise group = 8, williams exercise group = 8, control group = 8). Each group examined using the Borg scale in a reduction of low back pain, the EMG amplitude in a stationary sit-up position and in a stationary 1000 back extension position. The Results are as follow. 1. After the training period, the Mckenzie exercise group and the williams exercise group revealed reduction of low back pain, but the control group does not revealed it. 2. After the training period, there were no significant differences on the reduction of low back pain between the Mckenzie exercise group and the williams exercise group. 3. After the training period, no groups decreased on the abdominal muscle EMG amplitude. 4. After the training period, all groups revealed no significant differences on the abdominal muscle EMG amplitude. 5. After the training period, all groups decreased on the low back muscle EMG amplitude. 6. After the training period, all groups revealed no significant differences on the low back muscle EMG amplitude. Overall, the study suggested that the Mckenzie exercise and the williams exercise achieve the same effect on the reduction of low back pain, and the fact seems to be influenced by other factors without muscular adaptation.

  • Purpose : We described how the training of non-dominant hand that applicates the activity effects on dominant hand. Method : From November 6th to December 2nd 2013, We randomly selected 18 people that don't have a damage of hand function and are in college of K in Busan. (cross stitch training group 9 people, control group 9 people) All participants agreed on the research after fully being aware of training procedures and spontaneously conducted. Each training was practiced for 40 minutes in once every second day. One researcher deals with three participants at silent environment. We used the study measurement, Purdue pegboard, to investigate the sharpness of hand. To investigate the advancement of hand function caused by cross stitch training, we practiced three times estimations of primary one before training, middle one after 2 weeks training, last one after four weeks training and obtained the following results. Result : First of all, We found that the group of hand training appeared to be advanced of dominant hand's sharpness depending on the training period more than the control group. Second, We found that the group of hand training appeared to be advanced of non-dominant hand's sharpness depending on the training period more than the control group. Third, We found that the group of hand training appeared to be advanced of both hand's sharpness depending on the training period more than the control group. Fourth, We found that the group of hand training appeared to be advanced of the assembling function sharpness depending on the training period more than the control group. Conclusion : Put the results of this research together, we found that non-dominant hand training that used the activity was of help to advance the function of dominant hand. So, we thinks that hand training might help the recovery of affected hand function to the person that have a problem of hand function like hemiplegia patient. It will be required to practice the further study targeting the person that have a problem of hand function like hemiplegia patient. We hope that this research will be apply to clinical occupational therapy.

  • Seo Sang-cheon (1903-1950) was a sports leader and administrator who contributed greatly to the development of Korean sports after Japanese colonial era and liberation. And to us, he is known as the first person to introduce weightlifting to Korea. In this paper, through the main contents of the books of the 1930s related to this research topic, including the Modern Physical Fitness Promotion Act (1931) and the Modern Iron Stick Movement Act (1934), the main contents of Seo Sang-cheon's books related to physical training during this period, I would like to illuminate the characteristics such as infinite affirmation of the 'body training' and the exposure of disciplined upper body photographs in Seo Sang-cheon's writings related to physical training during this period. On the one hand, contrary to this, I tried to mention the regrets of his writings and political moves emphasizing the 'spirit' after the 1940s. We found that Seo Sang-cheon's early writings were focused on individual physical training, beyond the boundaries of nation and ethnicity. In contrast, his later writings reflect a shift towards thinking of personal physical training in alignment with the development of the state. We believe that this change in his writings demonstrates that Seo Sang-cheon's interests extended beyond physical education into political and social spheres, while also symbolizing a transformation in his perception of the body.

  • Purpose: The discovery of mirror neuron system may positively affect functional recovery; therefore, rehabilitation is needed that is practical for use in clinical settings. The purpose of this study was to examine the effect of action observation training on upper motor function in people who had suffered strokes. Methods: Three elderly patients with stroke, aged to years, were recruited from a stroke rehabilitation center. A nonconcurrent, multiple baseline subject approach was taken, with an A-B-A treatment single-subject experimental design, and the experiment was conducted for 3 weeks. The action observation training was repeated 5 times in 5 days during the intervention period. The arm function, including WMFT, BBT, and grip and pinch strength, was evaluated in each subject 5 times during the baseline period, the intervention period, and the baseline regression period. Results: The results of the evaluation for each subject were presented as mean values and video graphs. The WMFT scores of 2 subjects were improved during the intervention period in comparison with the baseline period, and this improvement was maintained even during the regression baseline period. The BBT and the grip and pinch strength were not improved. Conclusion: Based on these results, we suggest that the action observation training for 5 sessions was effective in improving upper limb function of stroke patients but was not effective in improving hand dexterity or grip and pinch strength.

  • 풍력 자원의 단기 예측 가능성은 풍력 발전 단지의 경제적 타당성을 평가하는 중요한 요소이다. 본 연구에서는 풍력 자원의 단기 예측 가능성을 향상시키는 방법의 하나로 베이지안 칼만 필터를 후처리 과정으로 적용하였다. 이때 추정된 모델과 관측 데이터의 상관관계를 평가하기 위하여 일정 시간 동안 베이지안 칼만 훈련 기간이 요구된다. 본 연구는 여러 훈련 기간에 따라 예측 특성을 정량적으로 분석하였다. 태백 지역에서는 3일 단기 베이지안 칼만 훈련으로 기온과 풍속을 예측하는 것이 다른 훈련 기간을 적용할 때보다 우수한 예측 성능을 보였다. 반면 이어도는 6일 이상의 베이지안 칼만 필터의 훈련 기간을 적용한 경우 가장 좋은 예측 성능을 나타낸다. WRF 예측 성능이 떨어지는 사례에서 베이지안 칼만 필터의 예측 성능향상이 뚜렷하게 나타나며, 반대로 WRF 예측이 정확한 지점에서는 필터적용에 따른 성능향상 정도가 약한 경향을 가진다.

  • This study evaluated and compared the effectiveness on upper motor extremity function between proprioceptive neuromuscular facilitation which has been frequently used in clinical practice, and action observation training in terms of improving upper motor extremity function. A study with a single-subject design (A-B-C-A') was conducted with a patient who was diagnosed with left hemiplegia. A repeated-measure analysis was conducted to assess results of the Wolf Motor Function Test (WMFT), Box and Block Test (BBT), and grip and pinch strength test performed daily in the study for 4 weeks. The results of the analysis indicated that the WMFT score, BBT score, grip strength, and pinch strength were improved from 29.60 to 39 (24.10%), from 1.67 to 4.93 each (EA) (66.22%), from 2.06 to 2.66 libras (lbs) (22.61%), and from 1.57 to 1.93 lbs (18.94%), respectively, from the baseline period to treatment period B. The values were improved from 29.60 to 42.20 (29.86%), from 1.67 to 7 EA (76.21%), from 2.06 to 3.47 lbs (40.57%), and from 1.57 to 1.67 lbs (6.12%), respectively, from the baseline period to treatment period C. From treatment period B to treatment period C, the WMFT score, BBT score, and grip strength were improved from 39 to 42.20 (7.58%), from 4.93 to 7 EA (29.56%), and from 2.66 to 3.47 lbs (23.20%), respectively, but pinch strength was decreased from 1.93 to 1.67 lbs (15.83%). In conclusion, proprioceptive neuromuscular facilitation and action observation training both have positive effects on upper extremity motor function. However, we suggest that the posttreatment effect of action observation training was better than that of proprioceptive neuromuscular facilitation.
