In this paper, we present the virtual dancing studio for distributed virtual environment. In this system, geographically distributed user shares the virtual dancing hall and interacts with each other. The participating object can be a graphical avatar or a live video stream. It allows the coexistence of graphic objects and real images in the shared virtual space. One of the main technical challenges in developing the distributed virtual environment is to handle excessive network traffic. In an effort to effectively reduce the network traffic, we propose a scheme to adjust the QoS of each object with respect to the distance from the observer in the virtual space. The server maintains the QoS vector for each client's shared space and controls the packet traffic to individual clients based on its QoS vectors. We develop a proto-type virtual dancing environment. Java based development enables the client to be platform independent. The result of experiment shows that the adoption of hierarchical QoS management significantly reduces the overall network traffic.

Brand Extension is a leading marketing strategy that makes use of brand assets, and it aims to see the success of a new product of a brand by utilizing the level of consumers' brand awareness, loyalty, resemblance, and image. However, the review of previous studies revealed that there were cases of fashion brands extending into coffee brands, but not vice versa. The study aims to suggest a new proposal to extend the coffee brand, the most preferred brand by consumers, to an effective office space service. It proposes making a napping and working area for the working Starbucks lovers who often go business trips and like to work in a private space. The researcher expects that the study will inform about the efficient manner to use office spaces including shared service and area.

Recently, the importance of non-face-to-face has been emphasized due to COVID-19, and the use of sharing spaces is also expanding. The use of uncontact check-in technology for access control of sharing spaces reduces waiting time and optimizes workers' efficiency, resulting in operational cost savings. In this paper, we propose a sharing space access management system based on a mobile key and RCU (Room Control Unit), access to the facility using a mobile key, and monitor the facility using an RCU. Proposal system is for shared accommodation, rental field (residence, sale-selling hotel), shared office, etc. when there is a one-time visitor on a specific day and time, the corresponding password is delivered to the mobile platform to expose and key the existing password. It is supported by a field-adaptive system that can reduce discomfort such as delivery. In order to test the operation of the proposed integrated system, tests were conducted according to scenarios to understand the overall status of the user's reservation, check-in, and check-out, and a 100% success rate was derived for each item by setting performance indicators to prove test reliability.

Since the late 19th Century, modern architecture of definite figure and form shared similar concepts on space and from with the abstract art, pursuing the geometric purity and the abstraction. So the reductive approach had been taken in modern architecture as well as on modern art. The 1960 minimal art had experimented an extreme reduction with the cubic forms and the plane canvases, embodying so called minimal-art content, it was just another version of modernism art interpreted by the extreme reduction. The reduction is a characteristics of modernism adopted in every art field, including architecture. Not from the apparent, but from the essential quality of architectural form, figure and space resulting from the reductive approach, a building in this trend schould be judged and appreciated. In many aspects, Korean traditional architecture has been shown the characteristics of Minimal Architecture. With these points of view, this study analyzes characteristics of Korean traditional architecture with above contents through the form and space.

This paper proposes a simple encryption technology for space-time block coding algorithm. Space-time block coding algorithm uses two antennas in transmitting data which consists of original data and transformed data for the purpose of combining in the receiver. This kind of two transmission antenna data could be exchanged and transmitted on each other's antenna individually, which can be used as a simple encryption algorithm. Encryption timing control informations should be shared between transmitter and receiver beforehand. It is shown that the proposed architecture can give performance enhancement compared with no encryption cases.

This paper presents a streetscape design for the 'Gaeksa-gil', located in Gosa-dong and Jungang-dong, Jeonju City, which length is about 830m and width is about $8\sim10m$. The goals of the design are to make a street on which people want to walk and rest both safely and pleasantly. To achieve these goals; concepts of identity, history, placeness, commercial vitality, environmentally-friendliness, safety, amenity , and democracy have been developed. For the pedestrian safety; shared street concepts, such as crank, salalom, fort, mini-rotary etc. are adopted. For design method, community participatory design is adapted. For the design theme; the axes of Time and Space are developed and streets are divided into 3 thematic spaces, such as 'History Street,' 'Nature Street,' and 'Culture Street.' The History Street, which belongs to Time axis, is a space for experiencing past, present, and future history of Jeonju city. Nature Street, which belongs to Space axis, is a space for feeling and loaming the nature of the city. The Culture Street, which also belongs to Space axis, is a space for experiencing the culture of the city. The community participated in the whole design process through the workshop, the internet website, the street events, etc.

Purpose: For the dignity of patients nearing the end of their lives, it is essential to provide end-of-life (EoL) care in a separate, dedicated space. This study investigated the utilization of specialized rooms for dying patients within a hospice unit. Methods: This retrospective study examined patients who died in a single hospice unit between January 1, 2017, and December 31, 2021. Utilizing medical records, we analyzed the circumstances surrounding death, the employment of specialized rooms for terminally ill patients, and the characteristics of those who received EoL care in a shared room. Results: During the 1,825-day survey period, deaths occurred on 632 days, and 799 patients died. Of these patients, 496 (62.1%) received EoL care in a dedicated room. The average duration of using this dedicated space was 1.08 days. Meanwhile, 188 patients (23.5%) died in a shared room. Logistic regression analysis revealed that a longer stay in the hospice unit was associated with a lower risk of receiving EoL care in a shared room (odds ratio [OR]=0.98, 95% confidence interval [CI] 0.97~0.99; P=0.002). Furthermore, a higher number of deaths on the day a patient died was associated with a greater risk of receiving EoL care in a shared room (OR=1.66, 95% CI 1.33~2.08; P<0.001). Conclusion: To ensure that more patients receive EoL care for an adequate duration in a private setting, additional research is necessary to increase the number of dedicated rooms and incorporate them into the hospice unit at an early stage.
