본 연구의 목적은 효과적인 국제적 지식이전에 영향을 미치는 요인들을 국제적 기술연수 사업을 경우를 통하여 분석하는 것이다. 국제적 기술이전에 관한 기존연구에서는 본사와 자회사, 합작투자 파트너들, 인수기업과 피인수기업 등과 같은 기업들을 분석대상으로 해 온 것에 반해 본 연구에서는 지금까지 거의 다루어지지 않았던 국제적기술연수 사업을 분석대상으로 하였다. 본 연구에서는 지식이전에 영향을 미치는 요인으로서 기업간 관계, 개인 및 조직차원의 흡수역량, 지식유형, 그리고 기술이전 성과로서는 연수생 개인 및 연수파견기업의 기술역량 성과와 경영관리역량 성과를 설정하였다. 실증분석에서는 한국 중소중견기업 기술자들이 일본기업 현장에서 연수를 받은 경우를 분석대상으로 하였다. 분석결과, 자본관계는 조직의 기술역량 성과에 영향을 미쳤다. 흡수역량의 경우는, 연수생의 커뮤니케이션 능력이 모든 성과에 유의한 영향을 미칠 정도로 중요했고, 연수생의 높은 기술수준은 아마도 연수에 대한 높은 기대수준을 가지게 함으로써 오히려 연수생의 기술역량 성과에 음의 영향을 미치는 것으로 나타났다. 또 연수파견기업의 흡수역량인 연구개발 투자정도는 개인차원의 기술역량 및 경영관리역량 성과에 유의한 영향을 미치는 것으로 나타났다. 그리고 연수대상 지식이 명시적 특성을 지닐수록 개인의 기술역량 및 경영관리역량 그리고 조직의 기술역량 성과에 긍정적인 영향을 미치는 것으로 나타났다. 또한 개인차원 성과는 지식이전 영향요인 일부와 조직차원 성과 사이에 매개효과를 가지는 것으로 나타났다. 마지막으로, 본 연구는 이러한 분석결과에 근거하여 국제적 기술연수 사업의 효과적인 실행과 관련한 시사점을 제시하였다.

The objective of this study was to determine the duration of maintained calf muscle flexibility gained in young adults with calf muscle tightness, as measured by increases in ankle active and passive dorsiflexion range of motion (DFROM) after three stretching interventions. Twenty subjects (5 men and 15 women) with calf muscle tightness received the following three stretching interventions in one leg (assigned at random): static stretching (SS), eccentric training on stable surface (ETS), and eccentric training on unstable surfaces (ETU). The subjects received all three interventions to the same leg, applied in a random order. Each intervention had a break of at least 24 h in-between, in order to minimize any carryover effect. Each intervention used two types of stretching: with the calf muscle stretched and both knees straight, and with the knee slightly bent in order to maximize the activation of the soleus muscle. All three interventions were performed for 200 seconds. We measured the duration of maintained calf muscle flexibility through active and passive ankle DFROM before intervention, immediately after intervention (time 0), and then 3, 6, 9, 15, and 30 min after intervention. We found a difference in the duration of maintained calf muscle flexibility between the three interventions. In the ETS and ETU interventions, a significant improvement in calf muscle flexibility, both ankle active and passive dorsiflexion ranges of motion (ADFROM and PDFROM), was maintained for 30 min. In the SS intervention, however, ADFROM before 9 min and PDFROM before 6 min were statistically different from the baseline. Our results suggest that ETS and ETU may be more effective than SS for maintaining calfmuscle flexibility in young adults.

The purpose of this study was to examine the effects of dual-task training (cognitive and exercise tasks) on the balance and gait performance of chronic stroke patients. Eighteen subjects with chronic stroke were divided equally into two groups, an experimental group and a control group. Subjects in both groups participated in an exercise program, performing the same tasks, for 45 minutes per day, three times per week for four weeks. The experimental group also performed additional cognitive task. The experimental group showed a more significant improvement than the control group on the Berg Balance Scale, the Timed Up and Go Test, the Korean Activities-Specific Balance Confidence Scale, and the Functional Gait Assessment (p<.05). The cognitive task error rates in the final week were significantly less than in the first week in the experimental group (p<.01). These results suggest that dual-task training for chronic stroke patients is effective in improving balance, gait, and cognitive abilities.

The objective of this study was to examine the effects of auditory biofeedback training and kicking training on walking times in patients with hemiplegia to determine if the effects of such training would be maintained even after stopping the intervention. Thirty hemiplegia patients were selected and randomly assigned to a control group of 10 patients to receive general exercise treatment; an auditory biofeedback training group of 10 patients to receive auditory biofeedback training, along with general exercise; and a kicking training group to receive kicking training, along with general exercise. All the patients received their respective training 12 times in total, three times per week for four weeks. In addition, all those in the control and experimental groups received the same general exercise treatment 12 times in total, three times per week for four weeks, and underwent follow-up tests thereafter. The patients’10m walking times were measured using a stopwatch. The significance was analyzed using repeated-ANOVAs. In cases where there were interactions between measuring times and groups, in each group were examined using repeated-ANOVAs. In cases where there were differences, post-hoc tests were conducted using repeated of contrast test. The 10m walking times of the control and experimental groups were significant differences in 10m walking times were shown between measurement times(p<.05), and significant differences in the interactions between measuring times and groups were shown between the groups(p <.05). However, no significant differences in 10m walking times were shown between the groups(p>.05). The auditory biofeedback training group showed significant decreases in walking times four weeks after the beginning of the intervention(p<.05) and significant increases eight weeks after the beginning of the intervention(p<.05). The kicking training group showed significant decreases in walking time four weeks after the beginning of the intervention(p<.05) and maintained the walking times without showing any significant differences eight weeks after the beginning of the intervention(p>.05). The walking speeds of only the kicking training group were maintained until eight weeks after the beginning of the intervention.

The purpose of this study was to analysis of the effect of proprioceptor training and vestibular organ training for balance ability. The subjects was consist of two different subjects group, proprioceptor training group and vestibular organ training group. Proprioceptor training group consisted of 10 subjects and vestibular organ training group consisted of 10 subjects. Training was performed 3 times per week, 30 minutes per day, for 3 weeks. Balance ability analysis was performed using Romberg's one leg standing test and BT4 when opened eyes and closed eyes. The analysis results were as follows. There was no significant differences in balance after the training in both groups when they opened their eyes(p<.05). But there was significant differences in balance after the training in both groups when they closed their eyes(p<.05). And there was no significant difference in balance after the training between the proprioceptor training group and the vestibular organ training group when they closed their eyes(p<.05). Given the above results, proprioceptor training and vestibular organ training enhanced balance but there was no significant difference between the two methods.

The purpose of this study is to investigate the problem on safety and health training system in Occupational Safety and Health Act(OSHA) and to find countermeasures to improve it in the construction industry. The questionary survey was done on aiming at tracing the legal drawbacks of safety and health training system. The questionary was prepared to target on site workers, management supervisors, and safety supervisors in various construction sites. After analyzing the answers from the survey, realistic and optimal countermeasures on derived problems were proposed. These should be included on the next revision of OSHA.

Prevention of the disasters is the best welfare to workers and it brings the growth and stability of an enterprise, finally uplifts the national competitiveness. Because small-scale businesses do not have safety and health managers, the government provides a wide range of safety and health management supports to small-scale businesses. However despite of this government's effort, the industrial accident rate of small-scale businesses does not decline, which is mainly because the projects are not differentiated according to the risk level of individual business. Therefore, this paper aims to obtain implications concerning a plan to conduct a reliable assessment of education through a safety job assessment, and to build a framework which may improve a technical area through the AHP analysis.

The purpose of this study was to investigate the effects of visual cue deprivation during sideways treadmill training in individuals with stroke. Twenty-eight stroke patients were divided into two groups, and each group participated in a sideways treadmill training session for 20 minutes, three times per week for 4 weeks. The eyes close group (15 subjects) performed this treadmill training with visual cue deprivation, while the eyes open group (13 subjects) performed it without visual cue deprivation. Gait function was measured in both groups before and after the training sessions with the Biodex Gait Trainer 2, which determined walking speed, distance, step length, and time on each foot. Balance was measured before and after each training period in both groups using the Five-Times Sit-to-Stand Test (FTSST), the Timed Up and Go test (TUG), and the seven-item Berg Balance Scale-3P (7-item BBS-3P). The eyes close group showed significantly improved gait function, walking speed, distance, step length, and time on each foot after training (p<.05). The eyes close group showed improved balance ability, FTSST, TUG, and 7-item BBS-3P test after training (p<.05). The findings indicated that sideways treadmill training with visual cue deprivation positively affects gait ability of stroke patients. Therefore, sideways treadmill training with visual cue deprivation may be useful for the recovery of gait ability of stroke patients.

The purpose of this study was to determine the effect of gait initiation training on gait and center of pressure (CoP) during gait initiation in stroke patients. Twenty-three subjects were randomly assigned to either an experimental group (EG) or a control group (CG). The EG received gait initiation training with increased CoP posterior distances the maximum the rear on gait training. The CG received general gait training. Both groups received training three times a week over a period of four consecutive weeks. The figures for CoP distances the maximum the rear, CoP distances time the mover the maximum the rear, the Tinetti Performance-Oriented Mobility Assessment (POMA), and gait velocity were recorded both before and after the training sessions for both groups. The EG’s results for CoP distances the maximum the rear, CoP distances time the mover the maximum the rear, and POMA improved after training (p<.05). In terms of the rate of change of CoP distances the maximum the rear, the EG demonstrated a significantly higher increase (p<.05) than did the CG. The results of this study suggest that increased CoP distances the maximum the rear affect the gait initiation and gait performance of stroke patients. Further studies with a larger sample size are necessary to verify the accuracy of the results of this study.
