Purpose : This study aimed to compare the effect of two conditions (visual and kinesthetic) of motor imagery training on static and dynamic balance. Methods : Fifteen patients with post-stroke hemiparesis volunteered to participate in this study. Two motor imagery training conditions, for 10minute trials, employed with audiotape instructions. Measurements were performed at pretest, posttest and 1-hour follow up in both static and dynamic balance. Results : Measures were significantly different both static and dynamic balance tests between treatment conditions (kinesthetic imagery more than visual imagery) at the pretest, post test, and 1-hour follow-up (p<.05). Measures of both static and dynamic balance tests, for both conditions, improved significantly from pretest to posttest (p<.05), and was maintained at 1-hour follow up. Conclusion : This study showed that both imagery training applications were effective treatment strategies for both static and dynamic balance. When comparing the two treatment conditions, kinesthetic motor imagery training was more effective than the visual motor imagery training in static and dynamic balance.

Purpose: This study compared the effects of the elastic resistance and general training for college Taekwondo athletes, and investigated the biomechanical ability and lower extremity function according to the movement speed of the knee joint. Methods: Twenty university student Taekwondo athletes participated voluntarily in this study. The subjects performed general resistance training for four weeks, followed by elastic resistance training for another four weeks. The biomechanical parameters during the fast and slow isokinetic conditions, Y-balance ability, and vertical jump ability were measured three times: before training, after general resistance training, and after elastic resistance training. Statistical analysis was performed under isokinetic conditions and the intervention effect. Results: The biomechanical ability differed significantly between fast and slow isokinetic conditions (p<0.05). An analysis of the training method revealed a significant difference in the maximum knee extension speed and the posterior-lateral direction of the Y-balance test (p<0.05). Conclusion: Elastic resistance training had a more positive effect on the functional task performance than biomechanical factors related to muscular strength compared to general resistance training. In addition, speed-related knee biomechanical information of subjects with strong physical abilities could be utilized in sports physiotherapy.

Purpose: The purpose of the study was to investigate the effects of HMD (head mounted display)-based virtual reality balance training on static balance in young adults, and whether appropriate balance training can help healthy adults to improve balance ability in daily living. Methods: The study subjects were 14 healthy adults. Subjects received 20 minutes of HMD-based virtual reality balance training 3 times per week for 4 weeks. Static balance was measured before, during, and after training and after one month. Static balance was measured in a total of 8 conditions, and the results were classified as visual (F1), somatosensory (F5-6), vestibular (F2-4), and central nervous system (F7-8). Results: The test results showed no significant difference in pre-training, post-training, and follow-up results under all conditions at Fourier index F1, F5-6, and F7-8 frequencies. For the F2-4 frequency, there was a significant difference before and after training under NC (neutral head position, eyes closed, firm surface) and PC (neutral head position, eyes closed, elastic surface) conditions. The NC condition returned a significant decrease of F2-4 frequency in post-training testing as compared to pre-training, and the PC condition showed a significant decrease of F2-4 frequency between the pre-training and mid-training tests, and between the pre-training and post-training tests. Conclusion: These results indicate that HMD-based balance training can improve balance ability, even in normal adults, and seems especially effective for vestibular function training.

본 논문은 민간직업훈련기관장 87명을 대상으로 조사한 실태조사 결과를 활용하여 선행연구들이 제시한 이론적인 직업훈련 민간위탁 성공조건에 대하여 직업훈련기관장들이 어느 정도나 동의하는가를 분석하였다. 분석 결과 이론모형에서 제시된 직업훈련 민간위탁 성공조건에 대하여 직업훈련기관장들의 대부분이 동의하는 것으로 나타났다. 직업훈련기관장들은 훈련의 질을 높이기 위해 민간위탁훈련기관을 대형화 전문화의 방향으로 구조조정할 필요가 있으며, 훈련비 지원액 중 성과보너스 비중을 높일 필요가 있고, 훈련기관별 훈련생 규모를 대폭 확대하여 규모의 경제를 통한 평균훈련비 인하가 필요하며, 훈련기관 평가 및 모니터링 과정에서의 거래비용을 낮추어야 한다는데 동의하는 것으로 나타났다. 다만 훈련생 모집방식에서는 직업훈련기관이 훈련생을 직접 모집하는 종전의 방식을 선호하는 것으로 나타나 이론모형과 반대의 결과가 나왔다. 이러한 결과는 현행 실업자훈련의 민간위탁사업이 위탁훈련의 성공조건의 대부분을 충족하지 못하고 있는 점을 민간직업훈련기관장도 동의하고 있다는 것으로서 정부가 직업훈련 민간위탁 성공조건에 부합하도록 직업훈련 민간위탁정책을 전환하더라도 대부분의 훈련기관이 동의할 것임을 시사하고 있다.

Mulberry silkworm is classified into uni, bi and multivoltine based on the frequency of diapause incidence. The variation in the incidence of diapause in bivoltine silkworm provides a unique opportunity to study the process of evolution of adaptive plasticity towards seasonal variations. The diapause expression in bivoltine silkworm is highly variable and is determined by environmental factors experienced by the maternal generation. Diapause in natural populations is functionally associated with the overwintering mechanism that facilitates survival in harsh winter conditions. In contrast, under standard commercial rearing conditions, the domesticated bivoltine silkworm is known to enter diapause in every generation. This paper presents a short review of the literature dealing with the role of temperature, photoperiod, diapause hormone and its receptor in diapause induction. Also, we briefly review the incidence of non-diapause eggs in bivoltine silkworm under controlled conditions.

Objectives: The aim of this study was to propose a standardized guideline for clinical training courses among dental hygiene departments of colleges in Korea. This study comparatively evaluated periods and durations of the curricula and specific domains, credits and hours of clinical training classes, and institutions providing practical lessons, and calculated the total credits and hours. Methods: From August 15 to September 15, 2017, a literature review was conducted in dental hygiene departments of 82 schools around the country in order to investigate the current conditions of clinical training in each educational system. Furthermore, 5 colleges were selected from each type of educational system, and their credits and hours for clinical training were analyzed in subjects of practical training for clinical dental hygiene, practical training for dental clinic, practical training for local community dental health, clinical training, and pre-clinical level practical training. The total credits and hours were calculated on the basis of analysis results. Results: The findings revealed that the hours of clinical training classes and hours per credit for practical training in the dental hygiene departments as well as the practical training institutions varied between the colleges. In some cases, the hours of practical training were not indicated. Standardized clinical training in the dental hygiene department was allotted 675 hours, whereas practical training in local community dental health studies was allotted 105 hours, which totaled to 780 allotted hours. Conclusions: There was a significant difference among the colleges in terms of the current conditions of clinical training in the dental hygiene department. The literature review revealed that a total of 780 hours was allotted to clinical training, and this was significantly more than the standard (500 hours) set by the. Moreover, these clinical training hours were lower than in advanced countries or other health and medical treatment occupations. Therefore, efficient improvement is required in order to provide a timely guideline for clinical training.

The aim of this study was to determine the effect of action observational physical training (AOPT) on manual dexterity and corticomotor facilitation in stroke patients. Ten hemiparetic patients participated in this study. Each subject was asked to participate the three conditions; base condition (Base), physical training (PT), AOPT. Participants were asked to observe the action in the video that a therapist moved the blocks during the AOPT conditions. Corticomotor facilitation was determined in three conditions by monitoring changes in the amplitude of motor-evoked potentials (MEPs) elicited in hand muscles by transcranial magnetic stimulation. MEP responses were measured from the first dorsal interosseous after participants attended to three conditions. For the manual dexterity, Box and Block test (BBT) was used. The results of present study were summarized as follows: MEPs amplitude significantly tended to be larger than PT and Base condition. The scores of BBT in the AOPT condition were also significantly larger than other conditions. In conclusion, this finding of present study indicates that physical training for observation of an action is beneficial for enhancing a dexterity of paretic arm in stroke patients.
