Objective : The purpose of this study was conducted to find scapular movement instability related with shoulder complex and provide strengthening the scapular muscles with proprioceptive neuromuscular facilitation(PNF). Methods : This is a literature study with books and articles, seminar note and book for PNF international course. Results : The scapular serve as the platform for humeral motions. The scapulothoracic articulation is stabilized and controlled, in part, by the scapular muscles. Therefore, if scapular muscle function is altered, then dysfunctional scapulothoracic kinematics may result. Strengthening exercise for scapular muscles are a common part of rehabilitation programs designed for patients with scapular instability. Conclusion : Treatment of the scapular instability is provided. It is that treatment with combination of isotonic, stabilize reversal on different patient's positions.

Until the up to day, we have known that a tight iliotibial tract has an influence on the patella, pulling it laterally and causing pain in patients with patellofemoral syndrome, so should be stretched as a part of physical therapy. But the iliotibial tract's function on the patella in subjects with PFS has not yet been proved and further questions need to be answered regarding the evlauation or treatment of a tight tract in patients with PFS.

The purpose of this study is to analysis of subjective well-being in the affects university life adaptation of department security programs in university. The subjects in this study were randomly sampled in Kyeong gi do in areas and 332 of department security programs student in university were finally selected. Analyses made by SPSS 17.0 have been applied to following outcomes. The findings of the study were as follows: First, The external situation and psychological physical which is a university life adaptation lower part variable in life satisfaction appeared with positive effects. The qualitative of education which is a university life adaptation lower part variable in life satisfaction appeared with negative effects. Second, The external situation and psychological physical which is a university life adaptation lower part variable in negative emotion appeared with positive effects. The qualitative of education which is a university life adaptation lower part variable in negative emotion appeared with negative effects. Third, The psychological physical which is a university life adaptation lower part variable in positive emotion appeared with positive effects. Fourth, The external situation and psychological physical which is a university life adaptation lower part variable in happy appeared with positive effects.

This Study was carried out to investigate the secondary cental nuclei innervating rat parotid gland. PRV-BaBlu as a neuronal tracer was injected into the left parotid gland and brains obtained through cardiac perfusion were treated by immunohistochemical staining. The results were as follows: L. The secondary central nuclei innervating rat parotid gland were paraventricular nucleus and central part of amygdaloid complex largely in diencephalon. 2. The paraventricular nucleus and central part of amygdaloid complex in diencephalon showed morphological asymmetry between PRV-BaBlu injected site and uninjected one. 3. The Ratio between total neurons and PRV-BaBlu infected neurons in paraventricular nucleus was $27.62{\pm}16.23\%$ in left and $12.78{\pm}8.69\%$ in right. 4. The Ratio between total neurons and PRV-BaBlu infected neurons in central part of amygdaloid nucleus was $14.25{\pm}9.26\%$ in left and $8.35{\pm}6.26\%$ in right.

Objective: This study was performed to evaluate the child-care teachers' job in relation to physical work. Background: Child-care teacher is directly related to the quality of child care. And their physical activity is higher than general education teachers because the proportion of day care is high. But analyzes of child-care teachers' job burdens and the work environment associated with physical activity is not well established. Method: To conduct this study, the child-care teachers' job was classified into 18 physical works. After classification, posture was evaluated by ergonomic posture evaluation schemes of OWAS, RULA, REBA and evaluated for each physical part. Next, musculoskeletal subjective symptoms were analyzed. Results: The results showed the following: The highest assessment on the posture evaluation was "helping children to ride a school bus", "feeding: meal/snack", "brushing children's teeth" and "arrangement of nap-stuff". The rank of high-risk assessment on the neck/trunk/leg part was arranged by: "feeding: meal/snack", "helping children to ride a school bus", "making nap", "arrangement nap-stuff" and "brushing children's teeth". The rank of high-risk assessment on the upper limbs part was arranged by: "helping children to ride a school bus", "the bust - group activity", "meal/snack time - preparing, feeding, arrangement", "nap time - preparing, arrangement", "brushing children's teeth", and "using the toilet". According to the results of each musculoskeletal subjective symptom, teachers ordered the pain area as follows: waist, shoulder, leg/feet, and neck, and they showed more pain on trunk than the upper limbs. Conclusion: To sum up the results from ergonomic posture evaluation and a subjective symptom, the following are high working pressures: "feeding: meal/snack", "the bust - group activity", "making nap", "brushing children's teeth" with deep bending and waist twisting, "helping children to ride a school bus", "brushing children's teeth" with lifting shoulder; "meal/snack time - preparing, arrangement", "nap time - preparing, arrangement", and "using the toilet" with moving or an up-down position in their job. Application: The results of this study might be information for improvement of the child-care teachers' job environment.

This paper surveys the physical properties of aramid and aramid/nylon hybrid air-jet textured yarns(ATY) for protective garments according to wet and dry texturing conditions. Aramid and nylon filaments were used to make two kinds of para-aramid ATY and four kinds of aramid/nylon hybrid ATY with dry and wet treatments. The analyzed physical properties of six specimens (made on the ATY machine) are as follows. The tenacity and initial modulus of aramid and aramid/nylon hybrid ATY decreased with the wetting and breaking strain; however, the yarn linear density of aramid and hybrid ATY increased with wetting treatment. The dry and wet thermal shrinkage of the hybrid ATY increased with wetting. The stability of aramid and hybrid ATY also increased with wetting. The physical properties of core/effect type hybrid ATY showed significantly more change than the core type hybrid ATY and the physical properties of nylon/aramid core/effect hybrid ATY showed significantly more change than the of aramid/nylon core/effect hybrid ATY. A higher bulky and breaking strain of hybrid ATY require ATY processing conditions of nylon on the core part with wetting and aramid on the effect part. ATY processing conditions for nylon and aramid on the core part with wetting are required for a higher tenacity and modulus. ATY processing conditions of nylon and aramid on the core with no wetting are required for a low thermal shrinkage.

This paper presents a robot system developed for medical purpose. A 6-degree-of-freedom robot was introduced for physical exercise and rehabilitation. This system was proposed for stroke patients or patients who cannot use one of their arms or legs. The robot system exercises the hemiplegic part based on the motion of normal part of a patient. Kinematic studies on the human body and robot were applied to develop the robotic rehabilitation exercise system. A clamp which acts as an end effector of the robot to hold a patient was designed and applied to the robot to guarantee the safety of patients. The proposed robotic rehabilitation system was verified by simulations and experiments on arm (elbow and shoulder) motion. Patients are expected to be able to exercise various motions by themselves with the proposed robotic rehabilitation system.

As a part of a series of previous studies, physical properties of various portions of a tire made of NR-Syn. R bloods were studied. 1. It was found, in general, most effective for tire tread when 50 parts of HAF black was blended with NR and Syn. R with a ratio of 70/30. 2. It was found that the use of SBR 1712 has an advantage in price, easy processing and physical properties than other synthetic rubber. 3. A technical compounding of various portions of a tire has to be determined for optimum cure conditions.
