목적 : 본 연구의 목적은 뇌졸중 환자의 손기능에 대한 근전도 바이오피드백 훈련의 효과를 조사하는 것이다. 연구 방법 : 발병 6개월 이상인 뇌졸중 환자 10명을 무작위로 실험군과 대조군으로 각각 5명씩 배정하였다. 실험군은 근전도 바이오피드백 훈련을 1일 1회, 주 5일, 6주 동안 수행하도록 하였다. 훈련의 1회기는 15초의 휴식기와 5초간의 추적과제를 수행하는 활동기로 구성되며 1회 훈련동안 추적과제를 총 40번 시행하였다. 반면, 대조군의 모든 치료 상황은 바이오피드백 훈련을 제외하고는 실험군과 같았다. 손기능을 검사하기 위하여 훈련 전·후에 개정된 Ashworth 척도, Fugl-Meyer 평가, 상자와 나무토막 검사, 뇌졸중 상지기능 검사를 실험군과 대조군 모두에게 실시하였다. 결과 : 실험군은 개정된 Ashworth 척도를 제외한 모든 검사에서 훈련 후의 결과가 훈련 전의 결과와 비교하여 통계적으로 유의한 차이를 보였다(p<.05). 대조군은 모든 검사에서 유의한 차이를 보이지 않았다(p>.05). 또한 집단간 비교에서 실험군의 훈련 후 손기능 향상이 모든 검사에서 대조군에 비하여 통계적으로 유의하게 높았다(p<.05). 결론 : 본 연구는 실시된 근전도 바이오피드백 훈련이 뇌졸중 환자의 손기능 향상에 효과적임을 지지한다.

본 연구는 레지오 에밀리아 접근법에 코칭기법을 도입한 레지오 에밀리아 코칭프로그램을 통해 영아의 문제해결력과 주도성에 어떠한 변화가 있는지 검증하는데 목적이 있다. 어린이집에 다니는 만 2세 원아 34명을 선정하여 관찰하였다. 남아 16명, 여아 18명으로 구성되어 있으며 교사 대 아동 비율은 1 : 7 보육하고 있다. 만 2세가 발달의 전조가 나타나는 중요한 시점일뿐만 아니라 신체적, 인지적, 사회적, 정서적, 언어적 기능들이 영아의 행동과 경험을 통해 구성되는 결정적인 시기이기 때문에 만 2세를 연구의 대상으로 선정하였다. 연구결과 레지오 에밀리아 코칭 프로그램을 통해 영아기 아동의 문제해결력과 주도성이 향상되었다. 레지오 에밀리아 코칭 프로그램은 영아기 아동들이 활동을 반복적으로 수행하도록 하였고, 또한 또래들과의 상호작용을 통해 협동을 자극하여 문제해결에 능력을 증진시켰다고 볼 수 있으며, 아동 스스로 자기를 발견하고 경청하기, 질문하기, 공감, 중립적 언어 등의 코칭 스킬을 통해 자신감을 키워 내적 자원을 강점으로 이끌어 낸 결과라 볼 수 있다.

The Railroad Safety Act was implemented in 2005 due to the increased concerns regarding railroad safety since the Daegu subway fire in 2003. In line with this, the Act became a standard to build the total railroad safety systems which has been overlooked compared to the quantitative growth of the railroad business. The minister of the ministry of Land, Transportation and Maritime Affairs lays down the Act for railroad Companies to conduct emergency programs in response to the emergency occurring on the railroad such as fire, explosion, derailment, etc. By enacting the Safety Act, the nation's construction of the contingency management system for railroad emergency increased", and it made the railroad company prepare the Emergency SOP by establishing 'The guideline on the Establishment of the railroad Emergency Plan' in order to support the efficiency of the Act. In line with this, I would like to analyze a matter of system development and the main function of the "railroad Emergency Training Program" for activation improvement of standardized operation procedure developed through the 'Total capitalize Safety Technology development'.

The purpose of this study was to test that motor skill training enhance motor function and cerebellar development. Using an animal model of fetal alcohol syndrome-which equates peak blood alcohol concentrations across developmental period-critifical periods for the effect of alcohol on body and cerebellar weigh was examined. The effect of motor skill training on motor function and cerebellar development of rat exposed alcohol on postnatal days 4 through 10 were studied. Newborn rats were assigned to one of two groups: (1) Control group (CG), via artificial rearing to milk formula and (2) experimental groups (EG), via 4.5g/kg/day of ethanol in a milk solution. After completion of the treatments, the pups were fostered back to lactating dams, and wearing they were raised in standard caged until they were postnatal 48 days. Rats from experimental group of postnatal treatment then spent 10 days in one of two groups: Experimental group II (EGII) was had got motor skill training (training traverse a set of 6 elevated obstacles) for 4 weeks. Experimental group I (EGI) was not trained. Before sacrificing, the rat got examined two behavioral test, body weigh and cerebellar weigh, then coronal sections were processed. The section was investigated the Purkije cell in the cerebellum using light microscope. The results of this study were as follows. 1. In body weight test, the outcome of alcohol groups were significantly lower than the normal group. 2. In cerebellar weight test, the outcome of EGI were significantly lower than CG and EGII. 3. In motor behavioral test, the outcome of EGI was significantly lower than NG and EGII. 4. In Purkinje cells counting test, the outcome of EGI was significantly lower than the NG and EGII. These result suggest that improved motor function induced by motor skill training after postnatal exposure is associated with dynamically altered expression of Purkinje cells and that is related with cerebellar function. Also, these data can potentially serve as a model for therapeutic intervention.

Prostaglandin () can facilitate release of epinephrine from the adrenal gland. The objective was to extend these findings and determine the effects of on sexual activity and semen collection training in sexually inexperienced boars. Boars (n=32; days of age) were moved individually once weekly to a semen collection room equipped with an artificial sow. Before entering the semen collection room, boar received i.m. treatments of at doses of 5 (n=8), 10 (n=8), or 20 (n=8), and control boar (n=8) were not treated. Reaction time (elapsed time after entering collection pen until the start of mounting) for boars receiving 5mg (), 10mg () was shorter (p<0.05) than for controls (). Duration of ejaculation (min) per session was longer (p<0.05) for (10 mg, 20 mg)-treated boars (, ), compared to control (). The number of training session per boars was less (p=0.056) for 10mg-treated boars (), compared to control (). Semen characteristic such as volume, concentration, the number of total ejaculated sperm, were similar for -treated and controls. There was no apparent difference on sperm movement characteristics (Mot: motility, VCL : curve linear velocity, VSL : straight line velocity, VAP : average path velocity, LIN : linearity) after semen preservation by collected with or without treatment. In summary, administration of in boars increased the sexual activity and facilitated the training boars to mount an artificial sow for semen collection, but did not affect semen characteristic.

The purpose of this study was to investigate the effects of the task-oriented training according to the application time with the change of motor and cognition function. Focal ischemic brain injury was produced in Sprague-Dawley rats (20 rats, 250±50 g) through middle cerebral artery occlusion (MCAo). Before MCAo induction, all rats were trained in treadmill training and Morris water maze training for 1 week. Then they were randomly divided into groups: Group I : MCAo induction (n1=5), Grop II: the application for simple treadmill task training after. MCAo induction (n2=5). Group III: the application for Morris water maze cognitive task training after MCAo induction (n3=5). Group IV: the application for progressive treadmill task training and Morris water maze cognitive task training after MCAo induction (n4=5). Modified limb placing tests (MLPTs) and motor tests (MTs) were performed to test motor function and then Morris water maze acquisition test (MWMAT) and Morris water maze retention test (MWMRT) were performed to test cognitive function. For MTs, there were significant interactions among the groups with the time (p<.001). Group IV showed the steeper increasing pattern than those in other Groups on the 7th and 14th day. For MLPTs, there were significant interactions among the groups with the time (p<.001). The scores in Group III. IV had showed the more decreasing pattern than those in Group I, II since the 7th day and 14th day. For MWMAT, there were significant interactions among the groups with the time (p<.001). Group II found the Quadrant circular platform showed the steeper decreasing pattern than that in Group I on the 9th, 10th, 11th and 12th day. Group III. IV found the quadrant circular platform showed the slower decreasing pattern than that in Group I, II, For MWMRT, there were significant differences among the four groups (p<.001). The time to dwell on quadrant circular platform in Group IV on the 13th day was the longest compared with other groups. These results suggested that the combined task training was very effective to improve the motor and cognition function for the rats affected on their focal ischemic brain injury.

The purpose of this study was to investigate the changes of the center of pressure (COP) trajectory in healthy elderly subjects while crossing an obstacle before and after participation in Tai Chi training. Forty healthy elderly subjects participated either in a 12-week intervention of Tai Chi training or in a health education program. The participants were divided into two groups (the experimental group and the control group). Subsequently, the participants were pre- and post-tested on crossing over an obstacle from a quiet stance. Participants in the experimental group received Tai Chi training that emphasized the smooth integration of trunk rotation, a shift in weight bearing from bilateral to unilateral support and coordination and a gradual narrowing of the lower-extremity stance three times weekly. The participants in the control group attended a health education program one hour weekly and heard lectures about general information to promote health. Performance was assessed by recording the changes in the displacement of the COP in the anteroposterior (A-P) and mediolateral (M-L) directions using a force platform. Participants in the Tai Chi group significantly increased the A-P and M-L displacement of the COP after Tai Chi training (p<.05). No significant differences in the A-P and the M-L displacement of the COP between pre-testing and post-testing in the control group were found. This study has shown that participation in Tai Chi exercise increased the magnitude of the A-P and M-L displacement of the COP, thereby improving the ability of healthy elderly participation to generate momentum to initiate gait. These findings support the use of Tai Chi training as an effective fall-prevention program for the elderly.

This study aimed at evaluating current sanitation management performances in Korean-Food restaurants by their operation types and to develop sanitary training posters based on the risk factors, in an attempt to improve the level of sanitation management in Korean food service facilities. Eighteen Korean-food restaurants that are managed by franchisor, franchisees as well as self-managed with large-scale and small-scale restaurants in Seoul and Gyeonggi-Do, were evaluated by on-the-spot inspectors with an auditing tool consisting of three dimensions, nine categories and thirty four items. Data were analyzed using SPSS. The total score of each group showed that restaurants managed by franchisees ranked the highest (59 out of 100 points), while self-managed, small-scale restaurants ranked the lowest (44 out of 100 points). In the categorization of sanitation management compliance, the dimensions of food hygiene during production recorded the lowest compliance rate of 47.7% (22.89/48.0 points) followed by the dimension of environmental hygiene 59.3% (20.17/34.0 points) and personal hygiene 60.5% (10.89/18.0 points). This indicated the need for urgent improvement. The items which showed the lowest compliance rates were 'proper thawing of frozen foods' (0%), 'notifying and observing heating/reheating temperature' (6%), 'using of hand-washing facility and proper hand-washing' (33%), 'monitoring temperature of frozen-foods and cold-foods' (35%), and 'prevention of cross-contamination' (36%) among thirty four items. Self-managed, small-scale restaurants, in particular, needed to improve sanitary practices such as 'sanitation education for employee', 'verifying the employee health inspection reports', 'storing food on the shelves 15 cm distance away from the wall', 'suitability of ventilation capacity of hoods' and 'cleanliness of drainage'. On the basis of the findings of this study, we developed sanitary training posters, especially for small-scale restaurant operators. This could be an effective tool to educate food service employees on sanitary knowledge and principles and could be used to improve the existing sanitary conditions in Korean food service facilities.

개발도상국을 중심으로 우리나라의 경제개발과 성장의 기반이 되는 인적자원개발과 교육시스템에 대해 지식과 경험의 공유 및 교류에 대한 요구가 점차 증가하고 있다. 우리나라는 교육 분야에서 이러한 요구에 적절히 대응하고 우리 교육 · 문화와 e- 러닝 산업의 해외진출 등의 기회로 활용하기 위해 국제교육협력을 위한 휴먼네트워크를 보완하고 강화할 필요가 있다. 그리고 이러한 요구들을 반영하기 위해 한국과의 교류협력에 영향력을 행사할 수 있는 해외 고위공무원 기업인 등을 대상으로 하는 초청연수 사업이적절한 대안으로서 추진되어 왔다. 그러나 공급자 중심의 사고방식， 민간의 참여부족， 사업성과 측정 미비， 사업추진 주제간 협력 부재 등으로 성과창출이 제한적이었다. 이러한 문제점에 대한 대안을 마련하고자 관련 선행연구를 기초로 본 블랜디드 러닝 기반 문제중심 국제연수과정의 개발과 함께 평가연구를 진행하였다. 평가연구는 크게 반응도 평가， 이해도 평가， 현업적용도 평가로 실시되었다. 그 결과 블랜디드러닝 기반 문제중심 국제연수과정이 교육생들의 이해도 향상은 물론 실제 각자가 가지고 있는 문제해결에 도웅을 주었음을 확인할 수 있었다. 그리고 이러한 결과를 바탕으로 국제연수과정개발에 있어서 고려점과 시사점을 논의하였다.

The objective of this study was to determine the effect of administration of Prostaglandin F2α (PGF2α) on semen collection training and semen characteristics in sexually inexperienced boars. Boars were moved individually to a semen collection pen and were trained to mount dummy sow. During the first and second semen collection secessions, 4 out of 17 boars and 4 out of remaining 13 boars allowed collection of semen. The 9 boars that failed semen collection from first 2 attempts received immediately 15 mg of PGF2α i.m. (intramuscular injection) upon entering the collection pen for semen collection resulted in successful semen collection from all 9 boars. Total numbers of spermatozoa were higher in PGF2α treated boars but there was no significant difference in % motility kinematics characteristics between control and PGF2α treated groups during 72 hr period. Overall, administration of PGF2α in sexually inexperienced boars increased the sex drive and facilitated the mounting activity to the dummy sow for semen collection.

The purpose of this study was to investigate the effect of balance training with upper extremity exercise on the improvement of balance performance in people who have had a stroke. Eighteen candidates who have all experienced a stroke, were living in Dong-Gu, Ulsan and were participating in a community based rehabilitation program, have been included in this study. The program was conducted three times weekly, 1 hour per session, for 7 consecutive weeks. Subjects were tested with 7 m and 100 m Timed Gait Test (sec), Timed Get Up and Go Test (sec), Functional Reach Test (cm) and 5 items of Berg's Balance Test at pre-training and post-training. Total balance index and balance ratios were measured by K.A.T. 3000. The balance training program performed by sitting on a chair and gymnastic ball and standing on stable and unstable surfaces during upper extremity exercises such as Proprioceptive Neuromuscular Facilitation (PNF) upper extremity pattern, picking a ball up from floor, throwing and catching it. After seven weekends of balance training, subjects showed a significant difference in balance test results. The exceptions were three items of Berg's Balance Test (p<.05). Balance index score and affected and unaffected side balance ratio had a larger improvement than pre-training (p<.05). The result of this study showed that intervention of this balance training program could improve the balance performance in people who have had a stroke.

본 연구는 협동학습에서 소집단 경쟁을 유도하는 집단보상과 소집단 구성원의 결속을 강조하는 협동기술 훈련의 효과를 비교하기 위하여 시도되었다. 이를 위하여 초등학교 6학년 3개 학급을 대상으로 문제중심 협동학습을 실시하였고 2개 학급에서는 각각 집단보상과 협동기술 훈련을 실시하였다. 학업성취도 면에서 이질적으로 구성된 소집단별로 진행된 협동학습 후에 세 집단의 과학성취도와 학습동기 점수를 성취도 수준별로 비교 분석하였다. 본 연구의 결과, 첫째, 집단보상과 협동기술 훈련이 과학성취도에 영향을 미쳤으며 학습자의 학업성취 수준에 따른 차이가 나타났다. 즉 성취 수준 상위인 학습자에게는 집단보상이 협동기술 훈련보다 효과적인 반면 하위인 학습자에게는 협동기술 훈련이 집단보상보다 효과적이었으며 중위인 학습자는 집단보상과 협동기술 훈련이 모두 효과적인 것으로 나타났다. 둘째, 집단보상과 협동기술 훈련이 학습동기에 영향을 미쳤으나 학습자의 학업성취 수준과는 관련이 없었다. 학습동기의 하위요소별로는 주의력 요소에는 효과가 없었으나 자신감과 만족감 요소에는 효과가 나타났다.

The present study investigates the effect of pronunciation training on Korean adult learners’ perception and production of English vowels, /i/, /I/, /u/, and /Ω/. The study examines 1) the effect of pronunciation training on perception and production and 2) the maintenance of the effect over a one-month period. The subjects were 10 Korean graduate students who took a 4-week long English pronunciation training course. They were tested before and after pronunciation training and tested again one month after the training. In each test, both perception and production of the vowels were tested to see if the subjects were able to distinguish tense and lax vowels. In the perception part, subjects listened for words and checked the vowel (either tense or lax) sound they heard. For the production part, subjects read the selected words which contained the target vowels. The results show that pronunciation training has an effect, which supports the teachability of phonology in adulthood; however, the maintenance of the effect demonstrated a difference between perception and production, in which the effect was maintained in production but not in perception. Based on the results of the study, implications are discussed.

The purpose of this study is to examine the effects of English oral presentation strategy training (OPST) in EFL contexts. For this study, eight university students of 4 high and 4 low proficiency level are selected. The participants were provided with an OPST over 5 weeks including 8 times of training. During the OPST, the participants learned 25 strategy, 17 verbal and 8 non-verbal strategies. The verbal strategies were again divided into two parts: general verbal strategies and genre specific strategies. For the validity of the present study a “triangulation” was achieved through the use of video recording, classroom observation, questionnaire, in-depth interview, and the native English speaker’s evaluation. The results of the study demonstrated that the participants showed some improvement in the use of presentation strategies, especially organizational and verbal components of the strategies rather than nonlinguistic components. The proficiency level of the participants had an effect on the frequency of use of strategies after the OPST. Overall, the OPST was found to have positive effects on the participants’ attitude toward English oral presentations. On the basis of the results of the study, some teaching implications for improving presentation skills in university EAP contexts are provided.
