The purpose of this study was to investigate the effects of serratus anterior strengthening exercises on scapular position and Visual Analog Scale (VAS) pain measurements taken at the resting position in young adults with adducted scapular. The exercise program included stretching of the scapular retractor and strengthening of the serratus anterior muscle. We measured the distance from the midline of the thorax to the vertebral border of the scapular with a tape line (Superior Kibler), and the distance from the 7th cervical spinous process to the acromial angle with 3-dimension motion analysis system, to compare the resting scapular position before and after exercise. Fifteen subjects with adducted scapular were recruited to compare the resting scapular position and VAS. The distance from 7th cervical spine process to acromial angle of the scapular and VAS decreased significantly (p<.01) after exercise, while the distance from the midline of the thorax to vertebral border of the scapular increased (p<.05). The conclusion is that the serratus anterior exercise program altered the resting scapular position and decreased VAS.

This study aims at first reviewing the international principles and domestic law and rules for juvenile inmates' contact with their family members. The convention on the rights of the child and the U.N. rules for the protection of juveniles deprived of their liberty stress the role of family contact and family strengthening strategies in achieving successful reentry and reintegration of inmates. And the Correction law and the Regulation for treatment of juvenile inmates define family strengthening program such as letter sending, visitation in person, family reunion events, telephone service but do not give more detailed directions for juvenile inmates. Based on the notion that the role of family contact and family solidarity is more significant meaning in psychological, mental development of youthful offenders, more active family involvement is inevitable for juvenile inmate's reentry. This article also shows current status of family contact of juvenile inmates with a small survey results. Most of them appear to maintain family contact via letter, telephone, and in-person visitation but, as expected, the frequency decreases as prior criminal records and the sentencing length increase. However, regardless of frequency of family contact, juvenile inmates expect that their family helps them in reintegrating into society. In that point, we need to think offender's family as necessary resources for successful reentry of inmates.

The limited walking ability after a stroke restricts a patient's independent mobility at home and in the community. It also brings about significant social handicaps. Therefore, it is necessary to improve walking ability in community-dwelling persons with stroke. The purpose of this study was to evaluate the effectiveness of gait training and muscle strengthening exercise of lower extremities in persons with chronic stroke. Nineteen community-dwelling individuals with stroke participated in this program. The exercise program lasted for seven weeks, with a 1-hour program twice per week, and it consisted of balance training, gait training, and strengthening of lower extremities. The outcome of the program was assessed by the gait speed, Wisconsin Gait Scale (WGS), Berg Balance Scale (BBS), and Stroke Impact Scale (SIS). Significant effects were found for the WGS, BBS, and mobility and hand function domain of the SIS (p<.05). It was found that short-term gait training exercise could improve quality of gait, balance, and mobility. Therefore, a more effective exercise program is required for community-based persons with stroke.

The purpose of this study was to determine the consequence of resistance strengthening exercise on the hip flexor and extensor performed to improve functional mobility in stroke patients more than six months post stroke. Seventeen patients were randomized into two groups. Both groups received conventional physical therapy for six weeks. In addition, the experimental group performed eccentric resistance strengthening exercise in the hip flexor and extensor using an isokinetic dynamometer. The hip flexor and extensor strength, stair up and down mobility, timed get up and go (TUG), 10 m gait velocity, and functional reach were repeatedly measured at baseline, three weeks, and six weeks after treatment. The results were as follows: 1. The experimental group improved more remarkably in the hip flexor and extensor strength, stair up and down mobility, and the 10 m gait velocity after three weeks and six weeks of treatment (p<.05), 2. The control group improved significantly in the hip flexor and extensor strength, and 10 m gait velocity after three weeks of treatment (p<.05), 3. At each three and six week point, the experimental group made greater gains in hip flexor and extensor strength, stair up and down mobility, and 10 m gait velocity than the control group (p<.05). In conclusion, it is desirable to perform resistance strengthening exercises combined with conventional physical therapy to improve functional mobility in chronic stroke patients.

Muscle weakness in the hemiplegia following stroke is an important factor which determines the quality of life in the future. Therefore, muscle strengthening exercise is essential for functional recovery in hemiplegic patients. Even though the popular conception is that muscle strengthening exercise causes spasticity and associated reaction that hemiplegia patients don't want, and that it disturbs functional recovery, recently there have been many new reports against that opinion. Therefore, the effects of strengthening exercise programs on functional recovery in hemiplegic patients are still controversial. The purpose of this study was to determine the effects of strengthening exercise programs for the knee joint using isokinetic exercise on the associated reaction of the upper extremities. Comparing the muscle activities of biceps brachii and triceps brachii during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise, we examined the increase and decrease of associated reaction. Twenty stroke inpatients participated in this study. Surface electromyography was used to get muscle activity data from biceps brachii and triceps brachii. The major findings of this study were as follows: 1. The flexor and extensor peak torque were significantly higher on the sound side than the affected side (p<.05). 2. Before and after strengthening exercise, there was no significant difference in muscle activities (surface electromyographic root mean square values) between the sound and affected side. 3. Muscle activities were examined during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise. There were significant differences in muscle activities between, before and during the exercises, during exercise and 5 minutes after exercise in the biceps brachii (p<.05), and during exercise and 5 minutes after exercise in the triceps brachii (p<.05). In conclusion, there was no relation between strengthening exercise and associated reaction in the upper extremities. Rather, muscle activities after exercise had a tendency to decrease relative to before the exercise. Thus, it is considered that intensive strengthening exercise contributes to improvement of functional recovery without increase in associated reaction in hemiparetic patients.

보강방법으로 많이 사용되고 있는 CFRP Plate 접착 공법은 보강된 부재의 내력 증가에 아주 효과적이나 에폭시를 이용하여 표면 부착하는 특성상 충분한 성능을 발휘하지 못하고 보강 판의 탈락으로 파괴에 이르는 조기파괴(premature failure)의 파괴 특성을 보인다. 이러한 보강 실험체의 파괴 특성은 철근비, 콘크리트 강도, 보강재 종류, 보강길이, 접착제인 에폭시의 물성 등의 변수들에 의해 영향을 받는다. 본 연구에서는 CFRP Plate로 휨 보강된 RC 보의 구조적 거동 및 보강재 조기 탈락에 대한 보완으로 보강 CFRP-Rod를 이용한 표면매립공법의 휨 성능효과를 보기 위하여 수행된 실험결과를 비교 고찰한다. CFRP Plate 외부부착 공법을 적용한 RC 보강보의 주요 변수로는 보강재 길이, 보강위치(보의 인장면 및 측면), 단부 보강철물 유무 등의 실험변수로, CFRP-Rod는 보강재 길이를 변수로 하여 실험을 수행하였다.

Before incorporating the earthquake-resistance design in design code(1988), most of existing residential buildings were built without having lateral resistance capacity in addition to their structural peculiarity such as exterior stair ways, exterior elevator room. For these reasons, the retrofitting research demands for existing buildings arise recently and many retrofitting methods are proposed. These tasks are irnportant to reduce the enormous economic loss and environmental issues. The objective of this study is to predict the perforrnance increase due to various strengthen schemes and suggest adequate strengthen methods for wall type apartment buildings not designed to resist earthquake.

The polymer-ceramic hybrid, known as 'ceramer', was synthesized by a sol-gel process by incorporating different amount of alkoxide as source of silicon in resorcinol-formaldehyde in presence of basic catalyst to get different percentage of silicon in ultimate carbonized composites. FTIR of the ceramer confirms that it is a network of Si-O-Si, Si-O-CH2 and Si-OH type groups linked with benzene ring. Different amount of silicon in the ceramer exhibits varying temperature of thermal stability and lower coefficient of thermal expansion as compared to pure resorcinol-formaldehyde resin. The lower value of CTE in ceramer is due to existence of silica and resorcinol -formaldehyde in co-continuous phase. Unidirectional composites prepared with ceramer matrix and high-strength carbon fibers show lower value of flexural strength at polymer stage as compared to those prepared with resorcinol-formaldehyde resin. However, after heat treatment to 1450℃, the ceramer matrix composites show large improvement in the mechanical properties, i.e. with 7% silicon in the ceramer, the flexural strength is enhanced by 100% and flexural modulus value by 40% as compared to that of pure resorcinol-formaldehyde resin matrix composites.

Rather than focusing on the general recognition of the area and extensive preference about its native cuisine, this study carried out more practical examination on the recognition of the native cuisine by presenting the more detailed introduction of the native cuisine in Hadong area. The findings of this study can be used as basic materials to devise measures for the instillation and advertisement of Hadong area's image, the development and maintenance of its native cuisine benefiting the activation of the local economy, and the reestablishment of Hadong area's native cuisine culture. First, the overall recognition of Hadong area's native cuisine was low and more consumption needs to be boosted by merchandising its foods through the strengthening of recognition. Second, correlation between this area's native cuisine was revealed and tables need to be set and menus need to be organized with this correlation in mind. Basic materials for suggestion sale were garnered. Third, given that most outside tourists visit Hadong by word mouth of all the information sources available, it is highly likely that positive word of mouth through satisfaction with native cuisine will raise the overall recognition of the area. Fourth, precise subdivision market and target market need to be specified. Though the factors like economic costs and the time required cannot be overlooked in strengthening recognition, consistent advertisement to the middle-aged people who are over 40 and live in Kyungsang-Do area will contribute to the fast rise in the recognition of Hadong area's native cuisine, leading to the possibility of economic development in the process.

A law of Korean product liability was enforced on 1st in July for 2002 years. Although it is later than the United States in 25 years, and more later than Japan in 7 years, it have been welcomed a new chances promoting the preservation of consumer"s safety and increasing business compactability toward the small and medium size enterprises. Up to now, The a large enterprise, which have concentrated in export of an advanced country, have already the resistant power against the law of Korean product liability, but the Korean medium and small-sized enterprises were concentrated mainly a domestic market or subcontracting business of a major big company. Relatively very week positions on this Low. If They cannot supply the most safest product in the market, then Those enterprise are confronting the difficulty for surviving. Now the product safety has become more important role to the small and medium size company. Therefore, this paper offered the object and the direction how the company must carry out measures on this product design stage applying safe engineering and Ergonomic Technology for the achieving ongoing development and progress of small ann medium size industry in Korea.

The purpose of this study was to investigate the effect of functional strengthening exercise on static and dynamic standing balance in a child with cerebral palsy. The subject was a 7 year old boy with diplegia whose Gross Motor Function Measure (GMFM) score was 80% along with G1 of the lower extremities in Modified Ashworth Scale. The subject was ambulatory with some degree of limitation and demonstrated muscle weakness and strength asymmetry in the lower extremities. A changing criterion design for a single-subject research was used for this study. The functional strengthening exercise consisted of lower extremity ergometer exercise and knee exercise with grading movement in standing position, each for 20 minutes, which lasted 18 sessions for 6 weeks. A knee extensor strength test on both extremities and standing balance test were conducted after each functional strengthening exercise. Two types of standing balance were tested: one leg stance test and functional reach test. One leg stance test was to evaluate static standing balance, and functional reach test was to evaluate dynamic standing balance. The results showed that the functional strengthening exercise had some positive effects on improvement of both static and dynamic standing balance, and there was a positive correlation between the knee strength and standing balance.
