South Korea's advertising market in 2012, growing at a standard 10 trillion, but most advertising is in the form of one-way communication by advertisers. In this paper, at the time they are attracting the interest of consumers, more recent placement by Facebook or Youtube propose an advertising platform using the Kinect motion-sensitive controller that can communicate with consumers. In the proposed platform, by the simple enjoyment of the game accept ads without resistance, and can deliver content more effectively than advertising indirectly passing. Had occurred in the existing Windows forms drawing problem was solved by using the XNA game engine using the Facebook API was designed so that it can be integrated with SNS.The scored elements to attract the interest of the users with the introduction of the ranking system and the user's face image to extract added to the story line, and increased immersive.

Purpose : To assess the width of the labial alveolar bone of the incisive canal and the width of the incisive canal on spiral computed tomographic images of the anterior portion of the maxilla. Materials and Methods : Study materials included 38 CT scans taken for preoperative planning of implant placement. Axial cross-sectioned image entirely showing the incisive canal was selected and scanned with 600 DPI resolution. The width of the labial alveolar bone of the incisive canal at an orifice to the oral cavity, middle portion, and an orifice to the nasal cavity and the diameter of the incisive canal at the middle portion were determined by two specialist using Digora for Windows 2.1 The statistical analyses were carried out using SPSS 12.0.1. Results : When the maxillary central incisors remained, the mean labial alveolar bone width were $6.81{\pm}1.41mm,\;6.46{\pm}1.33mm$, and $7.91{\pm}1.33mm$. When the maxillary central incisors were missed the mean width were $5.42{\pm}2.20mm,\;6.23{\pm}2.29mm$, and $7.89{\pm}2.13mm$. Conclusions : The labial alveolar bone width at middle portion and an orifice to the nasal cavity were of no statistical significant difference according to presence of the maxillary central incisors (P>0.05). The width between oral cavity and nasal cavity, middle portion and to nasal cavity revealed statistically significant difference (P<0.05).

Broadcaster and production studio inevitably take the risk in Korea because the outsourced drama is contracted before produced. However, it is important for both parties to share risk and reward. This study seeks to assess the fairness of the copyright contract between broadcaster and production studio by examining whether they both have the balanced risk and reward structure. For the study, revenue and cost elements with their amounts are identified, which come from TV commercials, oversea sales, the secondary windows, sponsorship, and product placement. Next, the revenue and COGS (Cost of goods sold) of broadcaster and studio are estimated for both cases of when drama becomes successful or not. The analysis reveals that the current copyright agreement allows broadcaster hold low risk but high reward whilst production studio takes high risk low reward. However, the result doesn't imply that government intervention is justified because demand and supply determine the negotiation power in a free economy.

Purpose: The purpose of this study is to suggest a systematic improvement plan for strengthening fire fighting ability of domestic rack- type warehouse buildings. Method: A fire case of small warehouse with sandwich panel structure and four design review of large warehouse with fire endurance structure were analyzed. Also, interviewed a group of 11 fire fighters who had 20 years field experience. Results: A provision of mobile equipment for initial fire fighting, accessibility of more than three sides, installation of internal entrance windows, proper placement of outdoor fire fighting equipment, image processing of fire site informations, and provide more incentives on the field commander are main factors of improvement plan. Conclusion: Effective standard operation procedures (SOP) and safety standards should be established and applied for each stage of the dispatch and on-site response considering the fire characteristics and risk factors of each warehouse by scale.

Purpose. The purpose of this study was to compare the effects of various surface treatments by measuring resonance frequency and histomorphometric analyses. Material and methods. In 5 adult dogs, the mandibular premolar were extracted. Six months later, 30 screw titanium implants (Dentium Co., Seoul, Korea) 6mm in length and 3.4mm in diameter, were placed in the mandibles of 5 dogs. Implants were divided into five groups following to surface treatment methods ; Group 1 is machined controls, Group 2 is sandblasted with large grit and acid-etched (SLA), Group 3 is anodized (Autoelectric Co., Korea, 660Hz, Duty10), Group 4 is hydroxyapatite(HA) coated by ion beam assisted deposition(E-beam), Group 5 is hydroxyapatite(HA) coated with Sol-gel coating process. Resonance frequency was measured implant placement immediately, and 3, 6 weeks and 10 weeks of healing perods. With the animal subject's sacrifice 10 weeks after implantation, implants were removed on bloc and histologic and computer-based histomorphometric analyses were performed. Histomorphometric analysis involved quantification of the entire bone to metal contact around the implants. Statistical analyses were performed using the SPSS for Windows (ver. 9.0 SPSS Inc.) Statistical differences were considered significant at P<0.05. Results. The results were as follows : 1) In five groups, mean value of resonance frequency analysis(RFA) were highest in group 5 (Sol-gel implant) at implantation and those of group 4 (E-beam)was highest at 10 weeks . but there was no correlation between surface treatments and RFA. 2) In all surface treatment groups, the RFA values of implants decreased until 3 weeks and increased to 10 weeks. 3) The percentage of direct bone-to-implant contact (BIC) had statistical significance between five groups in cancellous bone, (P<0.05) the percentage of bone density inside the thread had no statistical significance between five groups. (P>0.05) 4) There was a significant difference between cortical bone and cancellous bone in BIC. (P<0.05) and bone density. (P<0.05) 5) There was a correlation between the RFA value of implants at 10 weeks and BIC in cancellous bone, and between the RFA value of implants at 10 weeks and bone density in cortical bone. (P<0.05). Conclusions. These results indicate that surface treatment does not affect the implant stability in case of good bone quality.

Various customizing services are also being introduced in the fashion industry in line with the diversification of consumer tastes and the demand for small production of multiple varieties. However, barriers to entry are high for consumers who are not customized, and various functions are rather complicated. This study selected the three platforms that provide the most similar services to Marple, the No. 1 fashion platform sales, as comparative models and used them as a basic study for web-based fashion customization platform design through case analysis. As a research method, theoretical examinations were conducted through literature surveys, followed by web analysis based on layout, menu, color, icon, and interaction. The study found that the placement of options, the composition of menu windows, the number of point colors, and the use of icons without functions of metaphores hindered the use of customizing platforms. This work proposes a solution, and aims to contribute to increasing the usability of future customizing web by comprehensively analyzing the visual shaping elements of web platform design.
