This study was performed to investigate the effect of change of body posture on the rest position and the rotational torque movement of the mandible. Thirty dental students without any signs and symptoms of temporomandibular disorders and with natural dentition were selected for this study. Cervical inclination and the amount of the mandibular movement on protrusion, on left and right excursion, and on tapping in three body postures such as sitting position, supine position without pillow, and supine position with pillow were measured by goniometer, Cervical-Range-of-$Motion^{(R)}$, and mandibular tracking device, $BioEGN^{(R)}$ with $Rotate!^{(R)}$ program. The data obtained were classified and processed according to body posture and type of lateral guidance with SPSS windows program and the results were as follows: 1. There was significant difference among the three cervical inclinations by body postures. 2. Comparison of mandibular rest positions among body postures showed significant difference only for lateral distance in frontal plane, but comparison between before and after swallowing showed significant difference except for the lateral distance, vice versa. 3. Distance and amount of the rotational torque movement on protrusion and/or lateral excursions didn't show any difference by body posture. But by both body posture and lateral guidance type, there were slightly significant difference for some items. 4. A significant difference was shown for the rotational torque movement in frontal plane on tapping by body postures, for the lateral distance in frontal plane on sitting position by lateral guidance type, and for the rotational torque movement in frontal plane by both body posture and lateral guidance type.

본 연구는 두 가지 유형의 3차원 실내 공간 내에서 화재 발생시 연기거동에 미치는 복사영향을 알아보기 위해 자체개발한 SMEP(Smoke Movement Estimating Program) Seld 모델을 사용하여 수치해석하였다. PISO 알고리즘과 부력항을 포함한 수정 k - e 난류모델을 사용한 SMEP은 연속, 운동, 에너지, 농도 그리고 복사 열 전달 방정식을 풀었으며, 복사 열 전달 방정식의 해석을 위하여 S-N 구분종좌표법을 채택하여 사용하였다. 수치해석 결과 연기의 온도분포는 복사를 고려하지 않고 대류만을 고려했을 경우 실험치와 많은 오차를 보였으나 복사를 함께 고려했을 경우는 실험치와 작은 오차범위로 비슷한 경향을 나타내었다. 이것은 연기속에 포함되어 있는 연소생성물 중 H2O와 CO2 가스의 복사 영향 때문이며, 따라서 좀더 실제적인 화재해석에 있어서 복사는 반드시 고려되어야만 한다.

The direction of eye movement in Pleuronectiformes is species-specific. In farmed flounder, deviations in eye direction can reduce marketability. Therefore, we explored the effects of genetic and environmental factors on the direction of eye movements in the starry flounder Platichthys stellatus to address this economic challenge. Four pairs of female and male starry flounder broodstock, with eyes positioned to the right or left, were used in a mating experiment. The experimental groups were established with breeding seawater temperatures set at 10, 14, and 18℃ for the water temperature experiment. Whole-body samples of juveniles were collected to analyze the expression of genes related to eye movement and direction. The mating experiment results showed no significant differences in abnormal eye movement. In the water temperature experiment, the rate of abnormal eye movement was significantly higher at 32.19±1.33% in the 18℃ group than in the 10 and 14℃ groups. Genetic analysis of eye movement related to water temperature revealed that the expression of eye migration genes was significantly higher at 10℃. Moreover, no significant differences were observed in mating experiments. In conclusion, water temperature and not mating affected the eye movement of starry flounder.

The purpose of this study was to identify the effect of the craniocervical posture on swallowing and hyoid bone movement with sitting posture in wheelchair, and to provide basic data for developing a treatment program for dysphagia. A total of sixty healthy adults without a history of dysphagia who were guardians or care assistants of inpatients at Hospital K underwent video fluoroscopy performed by physiatrists from April to July 2009. The results of the fluoroscopy were analyzed based on the measurement of hyoid bone movements. The hyoid bone movement(horizontal, vertical, and diagonal) was significantly high in the neutral craniocervical, chin-tuck, and sixty degrees extension postures, in descending order(p<.05). It was found that the neutral craniocervical posture is the most effective posture for hyoid bone movement with sitting posture in wheelchair.

본 논문은 자활사업을 주요사례로 정부의 사회복지사업에 민간파트너로 참여하고 있는 사회운동조직이 어떻게 전문 사회복지기관과의 역학관계 속에서 자신의 자발적 정체성을 방어해나가는지 살펴보고자 한다. 군부독재가 막을 내리고 민주화와 진전되면서 과거 정부와 대립하던 사회운동단체들이 복지정책의 주요파트너로 부상했다. 저소득층의 일자리 지원사업인 자활사업도 빈민 실업운동진영과의 협력으로 도입된 복지제도이다. 그러나 사회운동에 대한 기존연구들은 사회운동조직이 제도화되면서 자발성이 훼손되고 사회복지 전문가와 기관들에게 헤게모니를 내놓게 된다고 지적해왔다. 이에 본 연구는 자활사업 관련 역사문헌, 심층면접, 참여관찰 자료에 대한 역사적 담론 분석을 통해, 자활사업의 도입시기부터 현재까지 사회운동조직의 자활사업 내 입지변화와 운동조직이 일선현장에서 사회복지진영으로부터 자신을 구별하기 위해 각 국면마다 구사해온 담론과 전략들이 있는지 추적했다. 본 논문은 사회운동과 사회복지의 갈등의 역사 속에서 사회운동진영의 생존전략들을 살펴봄으로써, 사회운동의 사회복지제도화와 전문화를 단지 사회운동의 지배체계로의 편입, 흡수, 종속으로 설명할 수 없고, 그 이면에 사회운동조직의 미시저항이 존재함을 드러내고자 했다.

Purpose: The purpose of this study was to investigate the effects of constraint-induced (CI) movement using self-efficacy on U/E function of chronic hemiplegic patients. CI movement discourages the use of the unaffected U/E, combined with intensive training of the affected U/E. Method: A non-equivalent pretest-posttest design was used. Study subjects were 40 hemiplegic patients conveniently selected from 2 different community health centers. The experimental subjects participated in the CI movement program for 6 hours daily over a period of two weeks. The exercises for affected U/E consisted of warming up, main exercise and ADL practice. To encourage the participants' behaviors self-efficacy enhancing strategies were used, which included performance accomplishment, vicarious experience, verbal persuasion and emotional arousal. Result: After 2 weeks of treatment, the grip power, pinch power, wrist flexion/extension, elbow flexion, and shoulder flexion/extension were significantly higher in the experimental subjects than in the control subjects. However, there was no significant difference in hand functions of the two groups. Conclusion: The above results show that the constraint-induced movement using self-efficacy could be an effective nursing intervention for improving U/E function of chronic hemiplegic patients. Long term studies are needed to determine the lasting effects of constraint-induced movement.

The purpose of this study was to determine the effect of Korean traditional dance movement training on balance, gait and leg strength in elderly women who are forced to remain at home. Fifteen elderly women of an experimental group between the ages 65 and 75 years who have normal vision and passed the hearing and Romberg test, participated in the 12 weeks' dance movement training. Fourteen subjects of a control group were selected. Korean traditional dance movement training was developed on the basis of Korean traditional dance and music by the authors. It took approximately 50 minutes to perform the dance movement program. The subjects of the experimental group practiced dance training for 3 times a week during 12 weeks. During the 50 minutes workout, the subjects practiced 15 minutes of a warm-up dance, 25 minutes of a conditioning dance, and 10 minutes of a cool-down dance. The intensity for the conditioning phase was between 60% and 65% of age-adjusted maximum heart rates. The balance, gait and leg strength were measured prior to and after the experimental treatment. Total balance scores of the experimental group were significantly higher than those of the control group. Scores of sternal nudge, one leg standing balance and reaching up among 13 items have significantly increased after the dance movement training. Total scores of gait of the experimental group were significantly higher than those of the control group following the korean traditional dance movement training. Scores of experimental group in step height, path deviation and turning while walking among 9 items have increased significantly following 12 weeks of dance movement training. The leg strength of experimental group was significantly higher than those of the control group following the Korean traditional dance movement training. The balance, gait and leg strength have significantly correlated in the experimental group following the Korean traditional dance movement training. The results suggest that Korean traditional dance movement training can improve balance, gait and leg strength in home bound elderly women.
