Coworking space is the ideal concept of small companies, freelancers, startups, and entrepreneurs operating out of a shared office space while working independently of one another. The coworkers share the core values of coworking: collaboration, openness, accessibility, sustainability, and community. Little academic research has been completed on the composition of coworking spaces and the businesses that use them. The purpose of this study is to examine the organization and characteristic of coworking space based on domestic and international cases for providing basic data on the coworking space plan. This study examined existing academic literature, media, online sources to assess the environmental background of worldwide coworking space, the current status, conceptualization, and membership plan that can be appled coworking spaces. The case study for coworking space is limited to the space where there is web site that is showed floor plan. Coworking spaces are designed to be environmentally friendly, offering common area with many facilities to encouraging community and collaboration. For creating ideal coworking space, the concept of coworking space must be recognized as a community space for interaction and creativity between people and space. Based on the result of this study, the appropriate zoning, circulation and specific floor plan of coworking space is needed for the next research.

The aim of this systematic review was to evaluate the effectiveness and complications of corticotomy and piezocision in canine retraction. Five electronic databases (PubMed, SCOPUS, Web of Science, Embase, and CENTRAL) were searched for articles published up to July 2017. The databases were searched for randomized control trials (RCTs), with a split-mouth design, using either corticotomy or piezocision. The primary outcome reported for canine retraction was either the amount of tooth movement, rate of tooth movement, or treatment time. The secondary outcome was complications. The selection process was based on the PRISMA guidelines. A risk of bias assessment was also performed. Our search retrieved 530 abstracts. However, only five RCTs were finally included. Corticotomy showed a more significant (i.e., 2 to 4 times faster) increase in the rate of tooth movement than did the conventional method. For piezocision, both accumulative tooth movement and rate of tooth movement were twice faster than those of the conventional method. Corticotomy (with a flap design avoiding marginal bone incision) or flapless piezocision procedures were not detrimental to periodontal health. Nevertheless, piezocision resulted in higher levels of patient satisfaction. The main limitation of this study was the limited number of primary research publications on both techniques. For canine retraction into the immediate premolar extraction site, the rate of canine movement after piezocision was almost comparable to that of corticotomy with only buccal flap elevation.

These days, it is getting important to have more chances to visit natural environment for the wellbeing life. The advancement of digital technologies allows us to get useful information regardless of time and location. In this paper, we investigate a way of improving user experience in the natural green environment using the digital technologies. This paper proposes a system called Green-UX-Story which supports users to create and share their story through the online and offline green experience. The system consists of two main systems: the "Story-Field" and the "Story-Tree". The Story-Field consists of a certain number of the Story-Trees allocated to a certain green site. In the Story-Field, users can see the Story-Trees that are owned by other users and share their stories. The Story-Tree contains the user-story in each branch and green information that are captured by the user on the web. The Story-Tree is generated using the L-system algorithm as the user adds stories. The main purpose of the system is to enable users to write their green stories from the both online and offline experiences. This paper describes the system configuration and the user scenario of the Green-UX-story.
