The purpose of the research is to investigate the effects of a portfolio system on students' socio-psychological classroom environments in elementary science class. Two schools were selected from a metropolitan area, a city, and one school from a rural area in central Korea. Two fifth-grade classes were sampled from each school selected, and one class is assigned to experimental group and the other to control group, respectively. The total number of participants of the study is 399. Portfolio system was administered to experimental group, and conventional teaching to control group for two and half month. WIHIC, an inventory to measure socio-psychological classroom environment, was administered as a pre- and post-test. Experimental group gained statistically higher scores on WIHIC after administering portfolio system. They showed more positive perceptions on sub-areas of WIHIC such as teacher support, task orientation, and equity. There is interaction between region and group: the effects of the portfolio system is highest in rural area, lowest in metropolitan area, and the city in between. Portfolio system have positive effects on students' socio-psychological classroom environments. Enhanced socio-psychological classroom environments is expected to contribute to positive self-concept, higher science achievements, and self-directed learning.

Purpose: Healthcare is on the whole a personal and critical service that consumer's use, whereas hospitalization is as a rule painful, because nature nurtures and Sun Light Luminosity for healthcare settings is considered healing. The performance and design of climate responsive buildings such as AKU requires a detailed study of attributes of climate both at micro as well as macro level. The therapeutic value of contact with nature through window view, greenery and landscape is calculated there. Method: A two prong strategy is been devised for this article, at micro level three typical morphologies are analysed by creating same environment of neighboring building on sun shading chart, radiation and temperature range. Since the analysis of local climate helps to determine the design strategies for hospital Healing Environment which is suitable for Karachi climate; in order to track the macro climatic behaviour, a considerable analysis of psychometrics chart for AKU Karachi are designed on Climate Consultant (CC) and analysed by Machine Learning. Climate Consultant proposes different design strategies suitable for Karachi. And on the other hand time wise illumination sources for clinical area which are then measured on psychrometric chart- according to singular space: multi patient admission, secondly: acute ambulatory ward, and tertiary: multi windowed space according to the mushrabiyah and sky light pattern. Result: Our findings support the hypothesis that windowed wall is 75-80% more healing wall; an accelerated evidence was found for healing at macro level if the form of the hospital is designed according to the climatologically preferences, whereas at micro level: the light resource becomes the staff attentiveness determinant. In Conclusion evidence was provided that the actual form of luminosity results consequently in satisfaction while light entering from several set of windows and other sources might be valued if design according to the healing environment. The data added on the sun shading chart to calculate rays entraining into space in patient room equal to 124416.21 Watts/ meter $m^2$ is calculated as precise healing rate-and is confirmed by questionnaire from patients belonging from each clinical stage having different illnesses.

Many reported methods assume that the faces in an image or an image sequence have been identified and localization. Face detection from image is a challenging task because of the variability in scale, location, orientation and pose. The difficulties in visual detection and recognition are caused by the variations in viewpoint, viewing distance, illumination. In this paper, we present an efficient linear discriminant for multi-view face detection and face location. We define the training data by using the Fisher`s linear discriminant in an efficient learning method. Face detection is very difficult because it is influenced by the poses of the human face and changes in illumination. This idea can solve the multi-view and scale face detection problems. In this paper, we extract the face using the Fisher`s linear discriminant that has hierarchical models invariant size and background. The purpose of this paper is to classify face and non-face for efficient Fisher`s linear discriminant.

Visual features of a mushroom(Lentinus Edodes, L.) are critical in grading and sorting as most agricultural products are. Because of its complex and various visual features, grading and sorting of mushrooms have been done manually by the human expert. To realize the automatic handling and grading of mushrooms in real time, the computer vision system should be utilized and the efficient and robust processing of the camera captured visual information be provided. Since visual features of a mushroom are distributed over the front and back sides, recognizing sides and states of the stalk including the stalk orientation from the captured image is a prime process in the automatic task processing. In this paper, the efficient and robust recognition process identifying the front and back side and the state of the stalk was developed and its performance was compared with other recognition trials. First, recognition was tried based on the rule set up with some experimental heuristics using the quantitative features such as geometry and texture extracted from the segmented mushroom image. And the neural net based learning recognition was done without extracting quantitative features. For network inputs the segmented binary image obtained from the combined type automatic thresholding was tested first. And then the gray valued raw camera image was directly utilized. The state of the stalk seriously affects the measured size of the mushroom cap. When its effect is serious, the stalk should be excluded in mushroom cap sizing. In this paper, the stalk removal process followed by the boundary regeneration of the cap image was also presented. The neural net based gray valued raw image processing showed the successful results for our recognition task. The developed technology through this research may open the new way of the quality inspection and sorting especially for the agricultural products whose visual features are fuzzy and not uniquely defined.

Recently, the interest in artificial environment made by mankind as well as natural environment has been increased. This interest in the environment began to be reflected in the physical education, which environmental problems affect modern people's living quality as a crucial factor affecting directly or indirectly our life. Furthermore, since we entered the era of mass sports the physical education subject has dealt with destruction of natural environment by constructing golf courses, ski slopes, etc., destruction of ecosystem by water sports, mountaineering sports, aero sports, etc., and noise pollution near the sport facilities. Therefore, the purpose of this paper is to examine the means to reinforce environmental education in many ways in the physical education concerning environmental problems. For this purpose this paper analyzed the contents of the 7th curriculum for physical education which can be thought to be teaching materials for environmental education, and described the contents in detail. Also, this paper established the orientation and goals of environmental education in the physical education subject and examined some important teaching and learning methods. In addition, this paper suggested some considerations concerning environmental education and a textbook model for the development of physical education textbooks connecting with the 7th curriculum for physical education, which is to suggest a means to connect physical education with environmental education smoothly. The physical education has an attribute that its activities like swimming, climbing mountains, and camping are performed outdoor. The physical activities in the physical education are, of course, performed in the environment, so we had better implement the environmental education including such physical activities at the same time with physical education. Also, there should be efforts so that the education through environment, the education about environment, and the education in the environment can be implemented along with the physical education.

The longitudinal integrated clerkship is an innovative approach in medical education that emphasizes continuity as a key principle to provide student-centered experiences and learning. Seoul National University College of Medicine decided to adapt longitudinal integrated clerkships to the new curriculum beginning in 2018, and therefore conducted pilot studies in 2016 and 2017. This study aimed to analyze the program evaluation results of the two pilot programs and discuss issues related to the successful implementation of longitudinal integrated clerkships in Korea. We conducted a focus group interview with nine students who participated in the 2016 pilot program and 13 students who participated in the 2017 pilot program. We also conducted a focus group interview with 11 faculty members who either participated in the pilot program or will participate in the main program. From the 2016 experience, we found that it is not appropriate to assign each patient to a single student and let the students contact their patients personally for feasibility and safety reasons. In the 2017 pilot program, we assigned each patient to a group of students, which made it more feasible for the students to follow-up with their patients. The students were satisfied with their new experience of longitudinal patient follow-up and regular meetings in the pilot program. Faculty emphasized the importance of establishing the course objectives and holding an orientation for the students and the faculty. Further study is planned to evaluate the early outcomes of the main longitudinal integrated clerkship.

Many of the universities in Korea recently is changing the school policy oriented from the supply approach to the demand as the case of business companies. Customer orientation is the key point of the customer satisfaction. But there are few studies focused on the satisfaction of students as a customer. In this paper, we studied the components of satisfaction in university life, the factors affecting on the satisfaction of students, and the relationship among them. The principal components of satisfaction in university life are services related to the activities of students, the utilization of welfare facilities, curriculum, the adminstration on students, and the department office. Factors affecting on the satisfaction of students are expectation, pride, self evaluation on learning, and special activities. Demographic variables, for example, sex, grade, colleges, and so on are also important factors. We also found the fact that the pride was the most important factor, and it gives positive drive on the satisfaction of students in university life. It gives us the important implication to the school policy.

This study examined the perception of gifted teachers toward 'conception of creativity personality education,' 'methodology of creativity personality education,' and 'support of creativity personality education' in the future gifted education. As a result, gifted teachers conceptualized creativity personality education as education to foster creative social capitals(social + moral leaders), which showed movement from gifted education focused on cognitive development into future-developmental orientation. Gifted teachers mentioned education to foster social sensitivity, creativity, and leadership as methodology of creativity personality education. More specifically, they recommended inductive curriculum in learning and teaching in order to encourage domain-specific giftedness. As pointing not to separate creativity personality education for gifted from a formal education but to deploy with conjunction with it, gifted teachers mentioned the social recognition for creativity personality education and the development of teacher's professionalism and educational programs.

My responses to Kim Kyung-Ok's Critique on my critique on the Hungerford approach can be summarized as follows; First, it was argued that possible confusions and misunderstandings around the concept of behavior in REB were mainly caused by Hungerford himself who has used the word in several different ways, from a bunch of overt actions to almost all kinds of responses including cognitive skills, without any clear operational definition of it for more than 20 years. It seems to be needed for future users of the word, 'Behavior' to Prevent unnecessary confusions by providing their operational definition of it. Second, REB is too ambiguous to be a legitimate goal of environmental education and too outcome-oriented to be a meaningful measure for environmental education research. Anyone who accept REB as a goal of EE or a measure for research should clearly suggest procedures and criteria for judging the environmental responsibility of actions under consideration. Third, the Hungerford approach has begun by realizing the limit of a linear traditional behavior change system and has been evolving toward a complex model with dynamic interactions among/between cognitive variables and affective variables. However, it still has one-way structural orientation toward 'Behavior' with no feedbacks. Addition of some feedback processes would make the model more flexible and realistic. Finally, both the Hines model and the Hungeford model were established based on a series of behavioristic studies including three doctoral dissertations equiped with a list of actions which were prejudged to be environmentally responsible by the researchers, not by the learners. What they were primarily interested in was not how mind functions during the learning processes but how learners' behavior can be effectively changed. Considering uncertainty and complexity associated with environmental problems, a great deal of efforts ought to be made toward more context-based and less normative studies applying cognitive psychology and quantitative approaches.

This article refers to the processions and the improvement of the 7th revised curriculum development for the Fisheries and Merchant Marine High School, published at Dec. 30, 1997. The general point of the 7th revised curriculum development was to cultivate creative Korean who will lead the epoch of globalization and information and to perform the learner-centered curriculum. Moreover, it defines the nature of Business High School not as completive but as continuing education. Based on this view, the improvment of 7th revised curriculum has been searched in varous sides. The group of general researchers and cooperators consisted of 12 members who were of university professors, teachers, related business men and executives in the administration branches, and the total researchers of 7th revised curriculum development were 90 members. The basic orientation of the research for the revised curriculum development was as following : The improvement of basic ability, job-analysis ability, integrity of theory and practice, acquisition of the certificate of national qualification, interrelation and cooperative role division between school and industrial fields, extension of self-decision ability of school and local society, protection of learner-selection right and maintaining close relations with the business-educational organization under life-long education system. Thus on the whole, the research for educational goals and contents, instructions, learning theory and evaluation is being processed with a high activity, based on the above mentioned plan of 7th revised curriculum development. At the same time, the methods and the models are being investigated. At last, it is to be noted that, in such as the 7th revised curriculum development research in this case, the effort should not be spared to harmonize the basic technological knowledge of the specialists in the Fisheries and Merchant Marine field and the cultural, liberal arts of personality education.
