In this study, the ways to improve the processes of training, employing and retraining secondary science teachers were investigated by a survey method. Particularly, the following five aspects of the processes were questioned to three major groups of people relevant to school science. A total of 384 responses (from 156 university teachers, 168 secondary science teachers and 64 student teachers) were analyzed through the frequency-analysis and crosstab-analysis of SPSS/$PC^+$ programme. The results of this study can be summarized as follows: (1) middle-school science teachers and high-school science teachers are needed to be trained separately in different systems, (2) the proportions of the faculty members majoring science education and science studies in the departments for science education are needed to be increased, (3) the proportions of the courses related to science education and general sciences in university curriculum are need to be increased, (4) the period of teaching practice in schools during university time should be increased up to five or six weeks, (5) the proportions of science education and general sciences in the examination for science teachers' employment should be increased and the examination should have more subjective type questions, and (6) the programmes for retraining science teachers should have more contents on science education which are directly relevant to school science.

본 연구는 활동보조인의 보수교육 수준에 따른 근무환경과 직무만족에 영향을 미치는 자기효능감과 직업의식을 파악하여 사회복지행정의 중요한 역할인 조직과 개인의 발전을 위한 인적자원개발과 관련된 전략 수립을 모색하는 근거자료를 제시하는데 있다. 이러한 연구의 목적을 달성하기 위해 경기권 지역에서 활동보조 역할을 담당하는 330명의 활동보조인을 대상으로 자료를 수집하였다. 이 연구에서는 설문지의 내용의 타당도 및 신뢰도를 검증하기 위하여 탐색적 요인분석과 확인적 요인분석 그리고 공변량구조분석을 위하여 Spss Amos 20.0 프로그램을 적용하였다. 결론은 다음과 같다. 첫째, 자기효능감과 직업의식이 근무환경에, 그리고 근무환경이 직무만족에 영향을 미치는 것으로 나타났다. 둘째, 자기효능감이 근무환경에 영향을 미칠 때, 보수교육경험 수준이 조절효과가 없는 것으로 나타났다. 셋째, 직업의식이 근무환경에 영향을 미칠 때, 보수교육 경험 수준이 조절효과가 있는 것으로 나타났다. 따라서 보수교육 수준이 높은 집단이 직업의식이 더 큰 것으로 확인되었다. 이러한 연구결과는 활동보조인의 보수교육이 직업의식을 강화시키는 조절효과를 나타남으로써 전문적 보수교육의 전략수립에 대한 기초자료로 활용될 수 있다.

This study is aimed at providing an analysis on the re-training needs in for environmental sector as well as on the current status on the employment of technicians in the environmental industry. The questionnaires of 450 technicians employed in 993 environmental businesses are collected. The survey questions were composed mainly of current status on the employment of technicians in the environmental field, specialty and duty in the working place, the relations with a licence, the level of satisfactory to duties and intention to leave hls/her job, difficultles in the working coditions, experiences of training related environmental techniques during a recent year, and the needs of re-training in the environmental industry. The policies on custom-oriented retraining and technical education, on the curricula by sector, on the establishment of retraining.

The career development of information security workforce affiliated in administrative department is very different from workforce affiliated in private companies. Their career development attempts are made not by voluntary motivation but by involuntary job movement by the principle of internal relocation. So they are not directly linked to monetary compensation or advancement. Due to the nature of the organization, their work attitude is very passive and there is little intention to turnover. They do not need professionalism, but they must be retrained according to the law. In this paper, we investigate and analyze the roles and responsibilities of information security workforce of each administrative department. And we do questionnaire survey to find out current roles and responsibilities of them will not affect the demand for retraining. Through these research, we would like to discuss how to manage information security workforce affiliated in administrative departments.

Core algorithm of deep learning Convolutional Neural Network(CNN) shows better performance than other machine learning algorithms. However, if there is not sufficient data, CNN can not achieve satisfactory performance even if the classifier is excellent. In this situation, it has been proven that the use of transfer learning can have a great effect. In this paper, we apply two transition learning methods(freezing, retraining) to three CNN models(ResNet-50, Inception-V3, DenseNet-121) and compare and analyze how the classification performance of CNN changes according to the methods. As a result of statistical significance test using various evaluation indicators, ResNet-50, Inception-V3, and DenseNet-121 differed by 1.18 times, 1.09 times, and 1.17 times, respectively. Based on this, we concluded that the retraining method may be more effective than the freezing method in case of transition learning in image classification problem.

During therapy sessions, feedback is often provided concurrently by the physical therapist as the patient attempts to perform a movement and after the movement attempt. This feedback is provided to enhance the patient's balance abilities. However, recent studies in nondisabled populations have suggested that frequent feedback may be detrimental to retention or learning of motor skills. This study compared the effects of 100% relative frequency of knowledge of performance (KP) with 66% relative frequency of KP for motor learning on balance retraining in patients with hemiplegia. Twenty patients with hemiplegic were randomly assigned to one of two experimental groups. The acquisition phase consisted of 16 blocks of 5 trials for 2 days (80 total practice trials). The retention phase consisted of 2 blocks of a short-term retention test, one day after the end of the acquisition phase and a long-term retention test, one week after the end of the short-term retention test. In the 100% feedback condition, participants received feedback after every practice trial. A faded KP schedule was used in the 66% condition. No significant differences were found between the two groups during all experimental phases (acquisition and retention phases), (p>.05). However, there were significant decreases in balance index for both groups of acquisition phase (p<.05). These results suggest that 66% relative frequency of KP is not more effective than 100% relative frequency of KP with respect to retention over time when hemiparetic patients attempt to learn balance.

Purpose: This study was conducted to determine the influence of inspiratory muscle exercise using visual biofeedback and inspiratory muscle exercise with diaphragm breathing retraining in stroke patients in regard to inspiratory muscle activity and respiratory function and to provide fundamental information on intervention for improvement of pulmonary function in stroke patients. Methods: The current study measured and analyzed inspiratory muscle activity and pulmonary function of 15 randomly selected subjects in a Biofeedback inspiratory muscle exercise (BIE) group that uses visual feedback and 15 subjects in the Diaphragm breathing exercise (DBE) group that uses breathing retraining before and after intervention. Intervention was performed for 30 minutes, 5 times a week, for 8 weeks. Subjects were measured for muscle activity of upper trapezius muscle and lattisimus dorsi muscle using a surface electromyography system and maximum inspiratory pressure was measured using a respiratory measurement device. For homogeneity test of subjects, independent t-test was performed and ANCOVA was performed for comparison of inspiratory muscle activity and pulmonary function between groups. Results: In the study results, the BIE group showed more significant muscle activity than the DBE group in upper trapezius muscle and lattisimus dorsi muscle (p<0.001). In addition, the BIE group showed more pressure than the DBE group in maximum inspiratory pressure (p<0.001). Conclusion: Based on the current study, performing biofeedback respiration exercise simultaneously with breathing retraining in stroke patients can provide more efficient respiratory physical therapy. In addition, it is considered that consistent study on the effectiveness is necessary to further improve clinical availability.
