Asymmetrical posture during static stance has been identified as a common problem in persons with hemiplegia. This study examined the effect of a purposeful exercise training program on symmetrical weight bearing in three adult persons with hemiplegia. Multiple baseline design was used. The intervention program, including ball throwing and catching, rolling ball catching and throwing, and Swiss ball pulling and stopping was introduced for 15 minutes each day during each intervention phase. Quantitative measurement of the weight distribution was taken with the Limloader. Visual inspection and mean of data revealed a significant improvement in symmetrical weight distribution. This result suggests that a purposeful exercise training program can be effective in helping persons with hemiplegia achieve symmetric stances.

Generative Adversarial Networks (GANs) models have developed rapidly due to the emergence of various variation models and their wide applications. Despite many recent developments in GANs, mode collapse, and instability are still unresolved issues. To address these problems, we focused on the fact that a single GANs model itself cannot realize local failure during the training phase without external standards. This paper introduces a novel training process involving multiple GANs, inspired by auction mechanisms. During the training, auxiliary performance metrics for each GANs are determined by the others through the process of various auction methods.

직원교육은 직원들의 직무 수행도를 높여 줄 뿐만 아니라, 직원 스스로 자기개발을 하도록 도와주며 기업에서는 장기적인 수익을 위한 투자가 될 수 있다. 따라서, 직원교육을 받은 직원들의 훈련동기요인은 무엇이며 교육만족도에 어떠한 영향을 미치고 교육만족도는 직무만족도에 어떤 영향이 있는지에 대한 실증적 연구가 필요하다. 따라서 본 연구는 외식업 종사자들의 인구통계학적인 특성에 따른 교육만족도의 차이를 알아보고, 훈련동기요인을 규명하며 교육만족도와 직무만족도 간의 관계를 규명하고자 수행되었다. 미 동남부 지역 15개의 레스토랑의 종사자들을 대상으로 설문조사를 실시하여, 192개의 유효한 데이터를 분석한 결과 훈련동기요인으로는 두 개의 'Intrinsic Motivation' 과 'Extrinsic Motivation'으로 추출되었으며, 이 두 개의 요인 모두 훈련만족도에 유의한 영향을 끼치며, 특히 Extrinsic Motivation이 교육만족도에 더 큰 영향을 끼침을 알 수 있었다. 이어 실시한 단순회귀분석 결과, 직원들의 교육만족도는 직무만족도에 긍정적 영향을 끼치고 있음을 알 수 있었다. 따라서 본 연구는 직원교육에 있어서 다양한 측면의 훈련 동기를 고려하고 직원 교육에 대한 만족이 직원들의 직무 만족에도 영향을 끼침을 고려하여 설계해야 함을 제안하였다.

In this paper, we investigate an individual channel estimation problem for multiple-input multiple-output (MIMO) two-way amplify-and-forward (AF) relay networks. To avoid self-interference during the estimation of the individual MIMO channels, a novel blind interference cancellation (BIC) approach is proposed based on an orthogonal preceding framework, where a pair of orthogonal precoding matrices is utilized at the source nodes. By designing an optimal decoding scheme, we propose to decompose the bidirectional transmission into a pair of unidirectional transmissions. Unlike most existing approaches, we make the practical assumption that the nonreciprocal MIMO channel and the mutual interference of multiple antennas are both taken into consideration. Under the precoding framework, we employ an orthogonal superimposed training strategy to obtain the individual MIMO channels. However, the AF strategy causes the noise at the terminal to be the sum of the local noise and the relay-propagated noise. To remove the relay-propagated noise during the estimation of the second-hop channel, a partial noise-nulling method is designed. We also derive a closed-form expression for the total mean square error (MSE) of the MIMO channel from which we compute the optimal power allocation. The simulation results demonstrate that the analytical and simulated curves match fully.

The aim of this study was to propose a multiple linear regression (MLR) equation to predict ultimate tensile strength (UTS) of 316L stainless steel with unspecified pit corrosion. Tensile specimens with pit corrosion were prepared using a potentiostatic acceleration test method. Pit corrosion was characterized by measuring ten factors using a confocal laser microscope. Data were collected from 22 tensile tests. At 85% confidence level, total pit volume, maximum pit depth, mean ratio of surface area, and mean area were significant factors showing linear relationships with UTS. The MLR equation using these three significant factors at a 85% confidence level showed considerable prediction performance for UTS. Determination coefficient (R²) was 0.903 with training and test data sets. The yield strength ratio of 316L stainless steel was found to be around 0.85. All specimens with a pit corrosion presented a yield ratio of approximately 0.85 with R² of 0.998. Therefore, pit corrosion did not affect the yield ratio.

This study addresses the effects of treadmill training on hyperextended knee and cadence in patients with hemiplegia. A single subject research design with multiple baselines across individuals was used for the study. Two patients with hemiplegia participated in the experiment. The experiment consisted of interventions where the patients were asked to ambulate for 15 minutes at a comfortable walking speed on the treadmill with 11% slope grade and were allowed to rest for 10 minutes. Patients, then, were asked to ambulated 20 meters at walkway. The number of occurrences of knee hyperextension and the total number of steps were recorded. The results showed that the occurrence of knee hyperextension decreased by approximately 30% after the first session of the treadmill training and continued to gradually decrease during the following sets of treadmill training. Meanwhile, there was a slight increase in the cadence to a negligible extent. These results suggest that the gait training on the sloped treadmill may be helpful for correcting the knee hyperextension in patients with hemiplegia.

Information on productivity of hospital personnel is required for optimum staffing and hospital management. This study deals with the quantitative aspects of workload of medical personnel in training hospitals by their specific characteristics. Specifically this study attempted to find relevant determinants of the productivity of medical personnel using multiple stepwise regression analysis based on data obtained from 135 training hospitals. The findings of this study were as follows: 1) Daily average number of outpatients and inpatients treated by a physician were 20.4 and 10.2, respectively. 2) Daily average number of patients cared by a nurse was 8.2. Daily average number of tests performed by pathologic technician and radiologic technician were 83.2 and 21.5, respectively. 3) Productivity of medical personnel were significantly different for the three groups of factors: hospital sire (number of beds, number of medical personnel per 100 beds): institutional characteristics (medical school affiliation, training type, profit status); and environmental factors (location, number of physician and beds per 1,000 population in the region). 4) The factors a(footing the productivity varied according to the types of medical profession: the number if beds, the number of physicians per 100 beds, training type, and profit status for physicians; the number of nurses per 100 beds, the number of beds, medical school affiliation for nurses; the number of physicians per 100 beds, the number of technicians per 100 beds, and ownership for pathologic technicians; the number o( technicians, training type, and the number of physicians per 100 beds for radiologic technician.

The Nuclear Power Plant(NPP) industry in Korea has been making efforts to reduce the human errors which have largely contributed to about 150 nuclear reactor trips since 2001. Recently, the Crew Resource Management(CRM) training has risen as an alternative countermeasure against the nuclear reactor trips caused by human errors. The effectiveness of CRM training in NPP industry, however, has not been proven to be significant yet. In this study a return on investment(ROI) model is developed to measure the effectiveness of CRM training for the operators in Korean NPP. The model consists of mathematical expressions including multiple variables affecting the CRM training impacts and nuclear reactor trips. Implication of the model is discussed further in detail.

Objectives: The purpose of this study was to investigate role·activity factors, ideal·value factors stress and stress amount relationship in clinical practice of dental hygiene students. Methods: The participate in this study were 231 dental hygiene department students. the survey was conducted from August 24 to September 30, 2018, using a structured questionnaire(1040460-A-2018-036). The collected data were compared and analyzed using a ANOVA and multiple regression. Results: The factors affecting the amount of stress were investigated. Role and activity factors stress in case of too much assignment, repeat simple and funtional work, ideal and value factors stress in case of utilized as a subsidiary work practice institution rather than clinical practice, lake of awareness that the training institution is a trainee. Conclusions: School institution and departments form organic relationships with industries. Uniform training guidance for each training institution does not help with diversity or creativity and problem-solving skills. It gives some autonomy to the training guidance of training institutions, also a clear standard for the contents of the training. we need a system that can provide and evaluate basic guidelines for what students can do in clinical practice.
