Based on Perceptions about Mathematics Teachers (PMT) perceived by high school students, measured by 2189 students from Seoul Educational Longitudinal Study 2014 (SELS 2014), latent profile analysis (LPA) identified five distinct types of student groups (positive, partial positive, middle, negative, extreme negative). These student of positive, middle, and negative groups are positive, moderate and negative perceptions about math teachers. Partial positive group generally had a positive perception about mathematics teachers, extremely negative group was very negative about mathematics teachers. Both of these groups had peculiarly inconsistent trends and several anomalies. The Multinomial logistic regression analyses also indicated that individual factors (gender, major, self-concept, resilience, self-assessment, career maturity), school factors (friendship, relationship with school teachers) and parental factors (academic-relationship, emotional-relationship) were significant predictors of PMT profile groups. The Analysis of variance also indicated that mathematics class (attitude, satisfaction and atmosphere), Mathematics achievement were significant predictors of PMT profile groups. The profiling of perceptions about mathematics teachers resulted in enhanced understanding of the complex range of processes students employed. During mathematics class, implementation of smooth interactions and communications between students and teachers added in the teaching and learning of mathematics.

There was a difference in recognition of chemical substances according to cognitive level of GHS, knowledge level of organic solvents and each department of workers. they were showed higher recognition of chemical substances by research group, partially group and good group. To identify the relationship between types of job classification(group of department, group of GHS cognitive level and group of organic solvents knowledge level) and the levels of recognition of chemical substances, a total of 153 workers in a small and medium business workplace. Descriptive statistics(SAS ver 9.2)was performed. the results of recognition of chemical substances were analyzed the mean and standard deviation by t-test, and anova, (P=0.05). These results In general, small- and medium-sized workplaces have low levels of GHS awareness and organic solvents knowledge. The perception of chemical substances according to the departments. In general, the demand for chemical substances education was highly suggested regardless of the job type. There was a significant difference in the perception of health, safety and practice according to the level of GHS cognitive, and a high perception in the incomplete group. There was not much difference in average awareness of health, safety and practice according to organic solvents knowledge level, but there was a high perception in good group. It is very important to regularly check the worker's perception of the workplace and identify problems with the work environment and improve the work environment. In addition, each department presents appropriate safety and health education such as chemical process safety, toxicity of chemical substances and human exposure. We also propose a chemical substances assessment and management plan that integrates safety and health.

환경영향평가 실무자들은 환경영향평가 정책을 수립하는데 매우 중추적인 역할을 하며, 환경영향평가 시행 시에는 이해관계자와의 정보공유, 의견조율 등을 통하여 환경 갈등을 예방하고 해소할 수 있다. 따라서 환경영향평가 정책 및 시행 등 시스템 전반에 대하여 실무자를 포함한 이해관계자의 인식을 파악하는 것은 환경영향평가의 개선 방향 및 정책 방향 설정에 도움이 될 수 있다. 그러나 현재 한국에서 시행되고 있는 환경영향평가 제도 및 운영에 대한 이해관계자의 인식 및 이해에 대한 정보는 부족한 상황이다. 그러므로 본 연구는 의사결정 수단이며, 환경 정보 분석기법을 통해 악영향을 최소화할 수 있는 사전예방적 기법인 환경영향평가 제도에 대해서 운영 및 절차상의 문제점들을 진단하고, 향후 환경영향평가 제도의 개선점과 시스템의 보완점을 모색하고자 하였다. 37개의 질문의 온라인 설문조사를 통해 환경영향평가 이해관계자 95명의 응답을 정리하였다. 이해관계자들은 현행 제도의 운영과 평가서 작성의 문제점 등에 대해 인식하고 있었으며, 이를 반영하여 나타났다. 부정 응답률(불만족 및 매우 불만족)이 높게 나타난 평가서 작성 기간 및 비용(49%), 새로운 방법의 도입(46%), 주민의견수렴 및 갈등관리의 항목(41%)은 추후 우리가 더 보완해야 할 부분이라 판단된다. 사회가 빠르게 발전하면서 제도도 그에 맞추어 보완이 필요하며, 조사결과 부정 응답이 높은 항목들에 대해 정책적인 개선 노력이 필요하다.

Objective: The aim of this study is to develop management guidelines and a procedure for an anthropometric suitability assessment of the main control room (MCR) in nuclear power plants (NPPs). Background: The condition of the MCR should be suitable for the work crews in NPPs. The suitability of the MCR depends closely on the anthropometric dimensions and ergonomic factors of the users. In particular, the MCR workspace design in NPPs is important due to the close relationship with operating crews and their work failures. Many documents and criteria have recommended that anthropometry dimensions and their studies are one of the foremost processes of the MCR design in NPPs. If these factors are not properly considered, users can feel burdened about their work and the human errors that might occur. Method: The procedure for the anthropometric suitability assessment consists of 5 phases: 1) selection of the anthropometric suitability evaluation dimensions, 2) establishment of a measurement method according to the evaluation dimensions, 3) establishment of criteria for suitability evaluation dimensions, 4) establishment of rating scale and improvement methods according to the evaluation dimensions, and 5) assessment of the final grade for evaluation dimensions. The management guidelines for an anthropometric suitability assessment were completed using 10 factors: 1) director, 2) subject, 3) evaluation period, 4) measurement method and criteria, 5) selection of equipment, 6) measurement and evaluation, 7) suitability evaluation, 8) data sharing, 9) data storage, and 10) management according to the suitability grade. Results: We propose a set of 17 anthropometric dimensions for the size, cognition/perception action/behavior, and their relationships with human errors regarding the MCR design variables through a case study. The 17 selected dimensions are height, sitting height, eye height from floor, eye height above seat, arm length, functional reach, extended functional reach, radius reach, visual field, peripheral perception, hyperopia/myopia/astigmatism, color blindness, auditory acuity, finger dexterity, hand function, body angle, and manual muscle test. We proposed criteria on these 17 anthropometric dimensions for a suitability evaluation and suggested an improvement method according to the evaluation dimensions. Conclusion: The results of this study can improve the human performance of the crew in an MCR. These management guidelines and a procedure for an anthropometric suitability assessment will be able to prevent human errors due to inadequate anthropometric dimensions. Application: The proposed set of anthropometric dimensions can be integrated into a managerial index for the anthropometric suitability of the operating crews for more careful countermeasures to human errors in NPPs.

Background: The presence of visuospatial impairment can make patients slow functional recovery and impede the rehabilitation process in TBI patients. Objective: The aim of this study is to investigate effects of prism adaptation treatment for functional outcomes in patients following traumatic brain injury. Methods: The subject received prism adaptation treatment for 2 weeks additionally during traditional rehabilitation for 4 weeks. The Patient has prism adaptation treatment while wearing wedge prisms that shift the external environment about $12^{\circ}$ leftward. The patient received 10 sessions, 15-20min each session. Outcome measures were visuospatial deficit(line bisection, latter cancellation), Visual and spatial perception(LOTCA-visual perception and spatial perception), motor function of upper extremity(FMA U/E; Fugl-Meyer motor assessment upper extremity, ARAT; Action research arm test), balance(BBS; Berg Balance Scale), mobility(FAC; Functional ambulation classification) and functional level(FIM; Functional independent measure). All Assessments took place on study entry and post-treatment assessments were performed at discharge from the hospital. Results: After prism adaptation, the visuospatial impairment scores improved as indicated in the line bisection(-15.2 to -6.02), latter cancellation(2 to 0) and LOTCA- spatial perception scores(7 to 9). The upper motor function improved as indicated in the scores of affected FMA U/E(21 to 40) and ARAT(4 to 22). Ambulation and balance improved as indicated in the BBS scores(25 to 38) and FAC scores(0 to 4). ADL function improved as indicated in the FIM total scores 54 to 70(motor 34 to 61, cognition 20 to 29). Conclusion: Prism adaptation did improve functional level such as motor functions and ADL abilities in TBI patient. Further research is recommended.

In this work, we studied consumers' attractiveness/usefulness perceptions (CAUP) of online commerce product photos when exposed to alternative dark/light user interface (UI) modes. We analyzed time-series EEG data from 31 individuals and performed neuroscience mining (NSM) to ascertain (a) how the CAUP of products differs among UI modes; and (b) which deep learning model provides the most accurate assessment of such neuroscience mining (NSM) business difficulties. The dark UI style increased the CAUP of the products displayed and was predicted with the greatest accuracy using a unique EEG power spectra separated wave brainwave 2D-ConvLSTM model. Then, using relative importance analysis, we used this model to determine the most relevant power spectra. Our findings are considered to contribute to the discovery of objective truths about online customers' reactions to various user interface modes used by various online marketplaces that cannot be uncovered through more traditional research approaches like as surveys.
