Purpose : This study is aimed to develop and validate the clinical practice education program and clinical competence scale of occupational therapy student. Methods : The development of the clinical practice education program used the delphi technique method, which had a total of five steps. Based on the occupational therapist's job analysis, the first stage assessed the importance of 21 experts, and the second stage examined the importance of 19 new specialists to derive constitutive factors. In the third stage, in-depth interviews were conducted with three experts based on the derived factors, and in the fourth stage, the final clinical practice education program was derived. In the final stage, the details of the clinical training program were drawn up based on the themes and were reviewed by two experts. Structured and unstructured interviews were conducted with 43 job experts. Results : The expert survey through the delphi technique was conducted three times, and content analysis and descriptive statistics were conducted to examine the distribution of responses. The final 11 educational program topics and contents were derived. Topics are confirmation of client information, evaluation and intervention, cognitive therapy, spinal cord injury, brain injury, musculoskeletal disorders, pediatric occupational therapy, interventions in activities of daily living, driving rehabilitation, vocational rehabilitation, occupational therapy assessment tool, safety training and management. Conclusion : The clinical practice education program reduce the difference between school education and clinical education of occupational therapy student. Occupational therapy helps college student understand occupational therapy practices and improve the quality of clinical education. Through more research and supplementation of clinical practice education programs in the future, it is suggested that clinical practice education be successfully operated in various practice institutions and used as basic data for designing and evaluating useful educational models.

The purpose of this study was (a) to develop carbon nanotube-based shock absorbers for reducing potentially harmful impact forces and excessive foot pronation, and (b) to briefly determine how the effects of carbon nanotube-based shock absorbers on biomechanical variance during drop landing. A university student(age: 24.0 yrs, height: 176.2 cm, weight: 679.5 N) who has no musculoskeletal disorder was recruited as the subject. Hardness, specific gravity, tensile strength, elongation, 100% modulus, tear strength, split tear strength, compression set, resilience, vertical GRF, and loading rate were determined for each material. For each dependent variable, a descriptive statistics was used for different conditions. The property test results showed that tensile strength, tear strength, split tear strength, compression set, and resilience in carbon nanotube-based shock absorbers were greater than general Ethylene Vinyl Acetate(EVA). These indicated that resistance against variable strength in developed carbon nanotube-based shock absorbers were greater than general EVA. In vertical GRF of CNTC was less than those of EVA during drop landing and loading rate of CNTC was greater than EVA. It seems that the use of CNT can be a effective way of reducing and controlling shock from impact.

Purpose: In Korea, the proportion of female workers among occupational injury is steadily increasing. The purpose of this study was to identify the workplace risk factors that threaten the safety and health of the female workers. Methods: Qualitative study was conducted, using focus group interview. Data were collected from five focus groups of eighteen female workers who were working in the manufacturing, health service, and educational service industries. Results: The seven themes of occupational safety and health risks of women workers are as follows: 1) Workplace with various risks; 2) Sliding, falling, burning, and cutting accidents; 3) Chronically lasting musculoskeletal symptoms; 4) Chemicals that may be harmful to workers; 5) Unprotected infectious disease; 6) Psychological safety accidents(Relationship conflict and emotional labor); 7) Loud, hot, stuffy, scary, and tired. Conclusion: The Occupational Safety & Health (OSH) Act should be rearranged gender sensitively and women's participation in the OSH decision-making process should be guaranteed. OSH education should be properly implemented in the field, and support should be provided for women workers in small businesses. A supportive organizational culture for marriage, pregnancy and childbirth should be established, and the working environment should be provided safely, taking into account gender differences.

The purpose of this study was to evaluate the biomechanical effect of sports taping on the lower limb during drop landing. Twelve male university students who have no musculoskeletal disorder were recruited as the subjects. Principal strain, median frequency, vertical GRF, loading rate, angular velocity and resultant joint moment were determined for each trial. For each dependent variable, paired t-test was performed to test if significant difference existed between taped and untaped conditions(p<.05). The results showed that principal strain of the thigh and the shank in taping group were significantly less than those found in control group. These indicated that sports taping may prevent excessive mechanical strain caused by impact force during the deceleration phase. Flexion(-)-extension(+) and varus(-)-valgus(+) resultant joint moment of the knee joint in taping group were greater than corresponding value for control group. It seems that extensor muscle of the knee joint were not only supported by sports taping during knee flexion but also sports taping is effective for minimizing the possibility of injury.

Objective: The purpose of this study is to review the hazards of whole body vibration(WBV) and prevent human injuries due to WBV. Background: Vibrations that shake the whole body in vehicles and vessels is WBV. Vibration at a specific frequency, and intensity in the human body can act as a hazard. But, it has not yet done enough research about effects of WBV. Method: We analyzed and reviewed occupational or ergonomic papers published past 30 years. Results: Exposure to whole body vibration can cause permanent physical injury or damage of the nervous system. In addition, it may cause problem in the cardiovascular system, digestive system, musculoskeletal system, endocrine system, reproductive system, and psychological system. The effect of vibration depends on its acceleration, duration, frequency, and direction. Conclusion: WBV-exposed human body experience a high risk of some illnesses such as lumbar spinal disorders. Some workers(bus drivers, truck drivers and heavy equipment operators) are the high risk population exposed to WBV. Application: The results of this study might help to judge and prevent occupational disease caused by WBV.

Background: Social status might be a determinant of occupational health inequalities. This study analyzed the effects of social status on both work environments and health outcomes. Methods: The study sample consisted of 27,598 wage employees aged 15 years and older from among the Korean Working Condition Survey participants in 2011. Work environments included atypical work, physical risks, ergonomic risks, work demands, work autonomy, social supports, and job rewards. Health outcomes comprised general health, health and safety at risk because of work, the World Health Organization-5 Well-being Index, work-related musculoskeletal disease, and work-related injury. Multivariable logistic-regression models were used to identify the associations between social status and work environments and health outcomes. Results: Employees in the demographically vulnerable group had lower occupational status compared with their counterparts. Low social status was largely related to adverse work environments. Especially, precarious employment and manual labor occupation were associated with both adverse work environments and poor health outcomes. Conclusion: Precarious and manual workers should take precedence in occupational health equity policies and interventions. Their cumulative vulnerability, which is connected to demographics, occupational status, adverse work environments, or poor health outcomes, can be improved through a multilevel approach such as labor market, organizations, and individual goals.

수영은 육상과 더불어 대표적인 기초 종목으로 손, 발을 사용하여 물속에서 헤엄치는 종목이기 때문에 기술적 훈련과 더불어 물의 압력에 따른 신체적 적응이 매우 중요하게 고려된다. 수영은 지상의 운동과는 다르게 물속에서 손과 발을 이용해 나아가고, 물의 저항으로 인해 근육을 움직이는 전신운동으로 높게 평가되고 있으며, 비만의 예방과 혈관질환의 치료에 많이 사용되는 운동 중 하나이다. 비교적 안전한 종목에 속하지만 다른 스포츠 종목들과 비슷하게 크고 적은 스포츠 상해가 발생 한다. 하지만 현재까지 수영 종목에서 유발되는 상해와 재활에 관한 연구 자료는 부족한 상황이다. 수영 선수의 상해는 일반적으로 고강도의 훈련, 많은 훈련 량 등으로 인해 발생하며, 수영 선수들에게 가장 많이 발생하는 상해와 질환으로는 극상근건염(supraspinatus tendinitis), 이두근건염(biceps tendinitis), 슬관절의 내측 활액막염(synovitis), 발등의 신근 건염(extensor tendinitis), 요통(low back pain)을 동반하는 척추분리증(spondylolysis), 척주전방전위증(spondylolisthesis) 등이 있다고 보고되고 있다. 또한 수영 경영 선수의 스포츠상해 부위 및 빈도조사 연구분석에 의하면 상해부위는 어깨관절(50%), 허리(23%), 하지(22%) 등의 순으로 높게 나타났으며, 상해종류로는 근육 손상과 인대손상이 대부분을 차지한다. 본 연구결과 수영 종목의 상해 부위는 상지(목, 어깨, 팔, 손목), 하지상해(무릎, 발목), 및 허리상해 순으로 나타났다. 그리고 영법별 상해분석으로 자유형, 배영, 접영 영법에서는 어깨 부위 상해가 많이 발생하였고 회전근개손상, 충돌증후군, SLAP (superior labral tear from anterior to posterior) 병변 순으로 나타났다. 평영 영법은 하지손상인 무릎손상, 평영과 접영은 척수상해, 접영은 허리상해 순서로 나타났다. 따라서 지도자는 선수들이 부상을 당하지 않도록 충분한 준비운동과 정리운동을 실시하도록 하고, 응급처치를 숙지하여 부상 발생 시 빠른 응급처치로 2차 손상을 예방할 수 있도록 해야 한다. 아울러 코치 및 지도자는 선수들에게 알맞는 재활 방법들을 처치하고, 선수들의 상해 예방과 처치에 대한 이해와 교육이 수반되어야 할 것이다. 추후 수영 영법 별 상해 예방과 상해 처치 그리고 재활방법에 관한 구체적인 기전적 연구들이 수행 되어져야 할 것으로 사료된다.
