Purpose: The purpose of this study was to develop a play education program to reduce children's fear of needle insertion to the implanted port, and to assess the effect of this program. Method: The play education program was composed of play education before needle insertion, encouragement during needle insertion, and a present to reward then after needle insertion. Measurement instruments were the Procedure Behavior Check List(PBCL) and Faces Rating Scale(FRS). Results: The first hypothesis, "the PBCL point of children with malignant disease would decrease after play education program", was rejected(before insertion : Z=-0.189, p= .850, during insertion : Z=-0.350. p= .727, after insertion : Z=-0.590, p= .555). The second hypothesis, "the FRS point of children with malignant disease would decrease after play education program education", was rejected(observer 1 : Z=-0.245, p= .806, observer 2 : Z=-0.912, p= .362, self-report : Z=-0.181, p= .856). The third hypothesis, "the Time of needle insertion would decrease after play education program", was rejected(Z=-0.464, p= .642). Conclusion: The effect on fear-reduction of play education program for children with malignant disease inserted implanted port was not significant but continuous education is needed for parents and children.

Purpose The study focuses on the physical activity behavior change effect of smart wristband, which is the most popular type of fitness tracker nowadays. The purpose of the research is to investigate how people's workout behavior may change after wearing a smart band and examine what kind of role persuasive design plays in behavior change. Design/Methodology/Approach This research employed an experimental study to examine whether the user's workout behaviors changed after using wristband from the "Behavior Wizard" perspective. A representative smart wristband from a major vendor was selected as the objects of experimental study. In the experiment, by comparing users' workout behavior before and after using the wristband, behavior changes of all the experiment participants were classified into one of the 15 behavior change types. Users perceived persuasive design characteristics were measured and group differences were tested among different behavior change groups. Findings This research found that nearly half of the participants changed their workout behavior while half retained their workout status or no exercise status. Half of the participants who did not do exercise in their spare time started walking in the experiment. Results also showed that participants who started working out perceived higher levels of persuasive design devised into the smart band than participants who preserved no exercise status, except for facilitation and reward strategies. Participants who retained workout and those who increased workout frequency perceived no difference in smart band persuasive design.

Learning portfolio is a collection of evidence that learning has taken place. It has gained its reputation as a useful assessment tool in the education of health professionals. The purpose of this study is to describe the pharmacy students' experiences and perceptions upon the introduction of a learning portfolio into the Introductory Pharmacy Practice Experience course. Methods: Fifty five students from one pharmacy school who used a learning portfolio to document their progress in the IPPE course participated in 16-item questionnaire exploring opinions and experiences of learning portfolio preparation, assessment, and personal and professional development and reflection. Results: Most students agree that a learning portfolio is a valuable tool in promoting self-directed and reflective learning. However most of them (46/55) also feel developing a portfolio is time-consuming, and when compared to their effort, an appropriate reward has not been given. Conclusion: To make the use of learning portfolios successful students should receive clear guidelines on their purpose, content and structure. Also the assessment criteria should be provided before the introduction of learning portfolio and their effort in developing learning portfolio should be rewarded.

Human resource theories of becoming entrepreneurs or self-employed rather than finding employment are compared as applied to fit the occupational data of technological entrepreneurs and technology jobs. The human capital theory posits that technological entrepreneurs are prepared to become a jack-of-all-trades with a variety of fields of education. Hobo theory of entrepreneurship assumes that entrepreneurs have strong taste against concentrating on a few activities, which tend to drive entrepreneurs away from employed jobs depressing their expected income. Another theory assumes that entrepreneurs have some unobserved productive qualities and abilities over employed people. Immigrant entrepreneurs could presumably be pressured out of employment under racial discrimination. Since technology jobs are mostly filled by those educated in the science and technology fields, and they presumably offer great reward to professional concentration, technological entrepreneurs may not benefit from becoming jacks-of-all-trades compared to finding employment in technological jobs income-wise. Asian immigrants in the 2000 US Census data are compared to white immigrants in technological jobs to test alternative human resource theories of entrepreneurship. Using English language ability as a proxy for the variety of education, I find in the white immigrant technological entrepreneurs support for the jack-of-all-trades theory, while in the Asian immigrant technological entrepreneurs hobo theory is supported. In the Asian technological workers only there appears the significant self-selection or comparative advantage component, while at the same time discriminatory components are significant.

뇌의 신호는 관측 대상의 상태 및 관측 위치에 따라 신호가 다양하게 변화하기 때문에 연구하기 쉽지 않다. 본 연구에서는 사람이 수면 전에 수행한 일이 수면 중에 미치는 영향을 분석하는 실험을 수행한다. 이를 위해서, EEG와 fMRI 장비로 피실험자의 뇌의 신호를 획득하고 분석한다. 시간에 따라 변화하는 뇌 신호를 분석하기 위해서 conditional random fields를 이용한다. 피실험자는 수면 전에 미로 찾기 게임과 얼굴 찾기 게임을 수행하며, 이 중 하나의 게임만 성공할 수 있다. 주어진 게임에 성공하면 이에 대한 보상을 받는다. 그리고 피실험자는 EEG와 fMRI 장비에서 수면을 취한다. 수면 중 깊은 잠으로 분류되는 N3상태에 도달하면, 얼굴 찾기를 성공한 그룹에서는 수면 전에 얼굴 찾기를 수행하는 동안 활성화 됐던 뇌의 영역이 미로 찾기를 성공한 그룹보다 상대적으로 유의미하게 활성화되는 것을 알 수가 있었다. 반대로 미로 찾기 성공 그룹에서도 같은 현상이 발생하였다.

This study examines the simultaneous impact of gender and administrative post on the research motivation of university lecturers. There are 475 selected questionnaires that are qualified for data processing and the collected data are analyzed by two-way analysis of variance (ANOVA). The results show the relationship between administration involvement and scientific research of lecturers. In general, lecturers with administrative post have higher research motivation than lecturers without administrative post. More specifically, the level of administrative post has positive correlation with research motivation of female lecturers, but has negative correlation of male lecturers. It means that a female lecturer with higher administrative post also has more motivation to conduct research. Conversely, the higher administrative post a male lecturer has, the less research motivation he is. The cause of this difference is the pressure of earning money on Asian men, including Vietnamese men, who are considered to be main breadwinners of their family. When having an administration post, the more chances male lecturers have to earn money, the less time they can spend for scientific research. This suggests that the solution for managers is to perform annual assessment, fulfill promotion process, build up motivation and reward system, and establish recruitment and promotion policies.

A smart tuned mass damper (TMD) is widely studied for seismic response reduction of various structures. Control algorithm is the most important factor for control performance of a smart TMD. This study used a Deep Deterministic Policy Gradient (DDPG) among reinforcement learning techniques to develop a control algorithm for a smart TMD. A magnetorheological (MR) damper was used to make the smart TMD. A single mass model with the smart TMD was employed to make a reinforcement learning environment. Time history analysis simulations of the example structure subject to artificial seismic load were performed in the reinforcement learning process. Critic of policy network and actor of value network for DDPG agent were constructed. The action of DDPG agent was selected as the command voltage sent to the MR damper. Reward for the DDPG action was calculated by using displacement and velocity responses of the main mass. Groundhook control algorithm was used as a comparative control algorithm. After 10,000 episode training of the DDPG agent model with proper hyper-parameters, the semi-active control algorithm for control of seismic responses of the example structure with the smart TMD was developed. The simulation results presented that the developed DDPG model can provide effective control algorithms for smart TMD for reduction of seismic responses.

The bed nucleus of the stria terminalis (BNST)-a key part of the extended amygdala-has been implicated in the regulation of diverse behavioral states, ranging from anxiety and reward processing to feeding behavior. Among the host of distinct types of neurons within the BNST, recent investigations employing cell type- and projection-specific circuit dissection techniques (such as optogenetics, chemogenetics, deep-brain calcium imaging, and the genetic and viral methods for targeting specific types of cells) have highlighted the key roles of glutamatergic and GABAergic neurons and their axonal projections. As anticipated from their primary roles in excitatory and inhibitory neurotransmission, these studies established that the glutamatergic and GABAergic subpopulations of the BNST oppositely regulate diverse behavioral states. At the same time, these studies have also revealed unexpected functional specificity and heterogeneity within each subpopulation. In this Minireview, we introduce the body of studies that investigated the function of glutamatergic and GABAergic BNST neurons and their circuits. We also discuss unresolved questions and future directions for a more complete understanding of the cellular diversity and functional heterogeneity within the BNST.

Neural Architecture Search (NAS) is cutting-edge technology in the machine learning community. NAS Without Training (NASWOT) recently has been proposed to tackle the high demand of computational resources in NAS by leveraging some indicators to predict the performance of architectures before training. The advantage of these indicators is that they do not require any training. Thus, NASWOT reduces the searching time and computational cost significantly. However, NASWOT only considers high-performing networks which does not guarantee a fast inference speed on hardware devices. In this paper, we propose a multi objectives reward function, which considers the network's latency and the predicted performance, and incorporate it into the Reinforcement Learning approach to search for the best networks with low latency. Unlike other methods, which use FLOPs to measure the latency that does not reflect the actual latency, we obtain the network's latency from the hardware NAS bench. We conduct extensive experiments on NAS-Bench-201 using CIFAR-10, CIFAR-100, and ImageNet-16-120 datasets, and show that the proposed method is capable of generating the best network under latency constrained without training subnetworks.
