This study was conducted for the purpose of evaluating the impressions gained by the members of the audience who have seen contents in a dome theater, based on their seating positions. Dome Theater Gaia provided the environment where the contents for evaluation were to be presented, and enquete (survey) was used as the investigative method. The survey results showed that the presentation of wide-viewing-angle three-dimensional (3D) contents proved effective in enhancing the 3D effect and the presence in a dome theater. Moreover, the study results confirmed that in relation to the impression evaluation of the contents for different seating positions, the optimal seating position varied according to the presentation method of the 3D and 2D contents.

This study describes a method of a human sensibility evaluation using photoplethysmogram(PPG) signal and a biofeedback algorithm to enhance the sensibility For this objective, the heart rate variability(HRV) is extracted from the PPG signal and using the HRV and its FFT the human sensibility is evaluated. The biofeedback algorithm is designed with motion image player interacting with the results of sensibility evaluation. The sensibility evaluation test showed feasibility of the designed method.

This paper deals with the ways that can improve the reliability of the course evaluation system based on reformation of the system and design of user interface for the practical applications. In the reformation of the system aspect, there are the improvements of the course evaluation questionnaires and the feedback of course evaluation to the lecturers. In the design aspect, a computer screen of the graphic user interface is redesigned to reflect the reformation of the system aspect issues. The results show the effectiveness in the reliability improvement.

This paper describes a new algorithm for human sensibility evaluation using two personality-group templates of electroencephalogram (EEG) signals. EEG signals of two groups arc collected in relaxed state, comfortable state and uncomfortable state. First of all, the characteristics of EEGs in relaxed state for two groups are compared. After verification of the results, an algorithm for sensibility evaluation is developed. In comparison of the characteristics for two personality-group EEG signals. there are distinct difference between the EEG patterns of the extrovert and the introvert. Upon these findings, the algorithm for human sensibility evaluation is designed. The results of the algorithm showed 90.0% of coincidence with given tasks. This seems to be compromising results for subject independent sensibility evaluation using EEG signal.

Existing trust evaluation models for wireless sensor networks can accurately and objectively evaluate trust value of nodes, but the nodes' energy saving problem was ignored. Especially when there are a few malicious nodes in a network, the overall trust value calculation for all nodes would waste lots of energy. Beside that, the network failure caused by nodes death was also not considered. In this paper, we proposed a method for avoiding energy hole which applied trust evaluation models and a trust evaluation method based on information entropy, so as to achieve the purpose of improving nodes utilization. Simulation results show that the proposed method can effectively improve nodes utilization, and it has reasonable detection rate and lower false alert rate compared to other classical methods.

Background: Radix et Rhizoma Ginseng (thereafter called ginseng) has been used as a medicinal herb for thousands of years to maintain people's physical vitality and is also a non-organ-specific cancer preventive and therapeutic traditional medicine in several epidemiologic and preclinical studies. Owing to few toxic side effects and strong enhancement on body immunity, ginseng has admirable application potential and value in cancer chemoprevention. The study aims at investigating the chemopreventive effects of ginseng on cutaneous carcinoma and the underlying mechanisms. Methods: The mouse skin cancer model was induced by 7,12-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13-acetate. Ultraperformance liquid chromatography/mass spectrometry was used for identifying various ginsenosides, the main active ingredients of ginseng. Comprehensive approaches (including network pharmacology, bioinformatics, and experimental verification) were used to explore the potential targets of ginseng. Results: Ginseng treatment inhibited cutaneous carcinoma in terms of initiation and promotion. The content of Rb1, Rb2, Rc, and Rd ginsenosides was the highest in both mouse blood and skin tissues. Ginseng and its active components well maintained the redox homeostasis and modulated the immune response in the model. Specifically, ginseng treatment inhibited the initiation of skin cancer by enhancing T-cell-mediated immune response through upregulating HSP27 expression and inhibited the promotion of skin cancer by maintaining cellular redox homeostasis through promoting nuclear translocation of Nrf2. Conclusion: According to the study results, ginseng can be potentially used for cutaneous carcinoma as a chemopreventive agent by enhancing cell-mediated immunity and maintaining redox homeostasis with multiple components, targets, and links.

본 연구는 과정 중심 평가가 학교현장에서 자연스럽게 도입되기 위해 과정 중심 평가와 기존 수행평가와의 공통점을 찾아보고 과정 중심 평가가 수학교과 인성 함양에 효과가 있음을 알아보고자 함이 목적이다. 선행연구를 분석하여 본 연구에서는 과정 중심 평가의 의미를 다양한 수행과제 및 평가방법을 도입하여 수업 중 실시하며 즉각적인 피드백을 통해 학생들의 성장 및 수업의 질을 향상시킬 수 있는 평가로 정의하였으며, 수학교과인성이란 수학수업시간에 쉽게 발현되고 함양되기 쉬운 인성요인을 뜻한다. 이에, 기하와 벡터 과목을 중심으로 과정 중심 평가의 실현 가능성에 대해 사례를 제시하고, 과정 중심 평가를 통한 수학교과 인성 함양에 효과가 있는지 알아보고자 하였다. 수학교과인성함양을 꾀하는 4가지의 과정 중심 평가(수학실험, 논리, 증명, 의사소통)을 인문계 고등학교 3학년 101명을 대상으로 2019년 3월부터 6월까지 수행한 후 수학교과 인성검사지를 활용하여 지수를 측정하였다. 대응변인 t-검정을 사용하여 결과를 분석한 결과 본 연구에서 실시한 과정 중심 평가는 수학교과 인성함양에 유의미한 효과가 있음이 나타났다.

본 연구의 목적은 학생부종합전형의 평가 요소와 기준에 대한 고등학교 교사와 학부모의 인식을 살펴보고 이를 통해 학생 역량을 보다 공정하고 정확하게 측정할 수 있는 대입 전형 개발의 기초 자료를 제공하는 것이다. 이를 위해 전국의 고등학교 교사 102명과 고등학생 자녀를 갖고 있는 68명의 학부모를 대상으로 온라인 설문을 실시하였다. 온라인 설문지는 J대학의 학생종합전형 기준을 바탕으로 제작되었으며, 크게 '서류평가', '면접평가', '기초설문'의 3영역으로 구성하였다. 이를 통해 얻은 결과는 다음과 같다. 첫째, 교사와 학부모 모두 학생생활기록부 중심의 학생부종합전형이 2015 개정 교육과정 운영의 활성화에 기여할 수 있는 대입전형이라고 응답하였다. 둘째, 교사와 학부모 모두 인성, 적성, 잠재력 모두 서류 평가와 면접 평가에서 중요한 요소라고 응답하였다. 셋째, 2015 개정 교육과정 활성화를 위해 학생부종합전형이 계속 유지되어야 하나 해당 전형의 공정성 확보가 선행되어야 함을 지적하였다. 마지막으로 연구 결과를 토대로 대입 전형 개선을 위한 제언을 제시하였다.

In recent years, there have been a number of concerns and measures surrounding 'Traffic Safety' for children. But, actually, safety measurements of 'School Zone' lack. This research thesis was designed to quantify risk degrees of 'School Zone', in a simple way, with the development of evaluation indicators to evaluate risk degrees of 'School Zone'. This is deems to be used for a guideline necessary for devising improvements or safety measures against 'School Zone' in the future. And, this is expected to be useful for managing and controlling safety each local facility about elementary schools.
