  • The purpose of this study is to establish the identity of the traditional residential space in Korea and Japan as analyzing the spatial characteristics and sociocultural roles of the 'in-between space' shown in their traditional dwelling space. Although they share culture area, it is meaningful to clarify the identity of both countries with many differences as the point of localization In globalization and the point of presenting the current and future directions of residential culture in both countries. Records and field studies have been carried out for the spatial characteristics and the sociocultural role focused on Ma-dang and Dae-chung in case of the 'in-between space' in Korean traditional dwellings and Inner housing, Doma, and Engawa in Japan. According to these findings, the spatial characteristics in common between Korea and Japan are open, half-open, separation, mitigation, integration, variation, continuation, hierarchy, mediation, and expansion. The 'in-between space', built by the separate Chae and Kan, of Korean traditional dwellings shows the separation by closed walls and the exclusive use by the fixed walls. In case of Japan, the integrated in-between space built by the separation of Kan shows open and connective tendencies and the variableness of walls has the tendency making ambiguous space with spatial softness. The sociocultural role of the 'in-between space' in Korean traditional dwelling space functions as the mitigation between the interior and exterior of the house as well as the male and female. Because the conception for protecting the private life is too weak, the sociocultural role of the 'in-between space' in Japanese traditional dwelling space seldom forms the space for an individual or the specific person among family. The space to welcome a guest functions as the mitigation between residents and outsiders as it is located in the inside of the private dwelling space.

  • We study near-infrared properties of the old open cluster King 11, based on the 2MASS photometric data. We determine the location of the red giant clump(RGC) in the (K, J - K) colo-magnitude diagram and derive the distance modulus of King 11 to be $(m-M)_0$ = $12.50{\pm}0.10$ using the mean K magnitude of RGC. From the red giant branch slope - [Fe/H] relation we obtain the metallicity of this cluster, [Fe/H]=$-0.17{\pm}0.07$. The age and interstellar reddening of this cluster are estimated to be log t = $9.48{\pm}0.05$, E(B-V)=$0.90{\pm}0.03$, by applying Padova isochrone fits to the data.

  • The vast mechanical systems could be classified as closed loop system, open loop system and open & closed (switching) system. In the closed loop system, the kinematics and dynamics of 3-D mechanisms will be reviewed and closed form solutions using the direction cosine matrix method and reflection transformation method will be introduced. In the open loop system, kinematic & dynamic analysis methods regarding the redundant system which has more degrees of freedom in joint space than those of task space are reviewed and discussed. Finally, switching system which changes its phase between closed and open loop motion is investigated with the principle of dynamical balance. Among switching systems, the human gait in biomechanics and humanoid in robotics are presented.

  • Currently, to prevent the spread of COVID-19 virus infection, gathering of more than 5 people in the same space is prohibited. The purpose of this paper is to measure the distance between objects using the Yolov5 model for processing real-time images with OpenCV in order to restrict the distance between several people in the same space. Also, Utilize Euclidean distance calculation method in DeepSORT and OpenCV to minimize occlusion. In this paper, to detect the distance between people, using the open-source COCO dataset is used for learning. The technique used here is using the YoloV5 model to measure the distance, utilizing DeepSORT and Euclidean techniques to minimize occlusion, and the method of expressing through visualization with OpenCV to measure the distance between objects is used. Because of this paper, the proposed distance measurement method showed good results for an image with perspective taken from a higher position than the object in order to calculate the distance between objects by calculating the y-axis of the image.

  • Nowadays, open education is popular in Korea. Various open education methods such as open time, open space, open curriculum, team teaching, small group learning are actively introduced into mathematics education. Current 'open education in mathematics' in Korea can be characterized as the application general education reform movement (open education movement) to mathematics education. This movement is interested in teaching methods rather than contents. In this article, I discussed with the limits and the problems of this application and argued that not the method-centered open general education reform movement but the content-centered mathematics education's own reform movement is necessary for the true mathematics education reform.

  • The functions of urban open space, which embraces community revitalization, are diverse. It is the means of public healthcare, learning centers for children, hub of arts and cultural programs, as well as promoter of urban tourism. However, in-depth discourse and research on the topic of urban open spaces has been limited so far. Hence, this study aims to investigate the motivations and satisfaction of visitation based on four representative waterfront open space in Seoul; Cheongyecheon Waterfront, Seoul Forest Park, Seonyudo Park and Banpo Hangang Park. The methods of study are literature review, observation investigation, and questionnaire survey. The findings are analyzed through the Exploratory Factor Analysis, Reliability Analysis, ANOVA Analysis and Regression Analysis by SPSS 18.0. The results of the study are as follows. First, urban waterfront open spaces in Seoul has 5 factors of visitor motivation; community amenity, nature access, cultural and educational assets, aesthetic enjoyment, and lastly means of escape. Second, factors of recognizing urban waterfront open spaces as community amenity and nature access indicate meaningful differences in visitor's perception by spatial characteristics. Third, distances between the destination and the visitor's residence influence significantly their perceived motivation. Close-range visitors perceived nature access as a principal factor, whilst medium to long-range visitors perceived visitation for aesthetic purposes more importantly. Lastly, the will to escape was shown as the influential factor in visitor satisfaction. Visiting open spaces for the enjoyment of nature and aesthetic purposes were factors that also closely relate to visitor satisfaction. In addition, it was found that there are different visitor motivations that influence visitor satisfaction in accordance with the spatial characteristics of each open space. In summary, it can be said that urban waterfront open space is a hybrid space connected to various types of urban contents beyond daily experiences. It was found that several visitor motivations including community development, design aesthetics, education and culture, entertainment, enjoyment of natural landscape, and relaxation, affect the overall satisfaction of the visiting experience. It is anticipated that the results of the study will be used by the local government in setting up strategies for the creation and management of successful urban waterfront open space, and for those involved in planning and design act as a starting point for spatial programming and amenities arrangement in accordance to the city's tourism and urban marketing approach.

  • The purpose of this study is to explore the possibility of the planning method of traditional market as the urban public open space and to attempt to create the essential reformation of traditional market place. The design concepts of the Moran traditional market project are establishing module system based on function of traditional market to accomplish the practical needs of vendor and consumer and expressing the liquid and autonomic characteristics of Moran traditional market to find the new and substantial schemes of public open space. The functional design module of the market place is based on 2.1m $\times$ 2.1m grid system which is minium market unit, and it is extended to 8.4m $\times$ 8.4m basic structural module and to 50.4m $\times$ 50.4m plaza unit.
