한국의 광고시장은 2012년 기준 10조원 규모로 성장하고 있으나 대부분이 광고주들에 의한 일방향적인 소통형태의 광고이다. 최근 Facebook이나 Youtube등에 의한 간접광고가 늘어나고, 이들이 소비자들의 흥미를 끄는 시점에서 본 논문에서는 모션인식 컨트롤러인 Kinect를 이용하여 소비자와 소통할 수 있는 광고 플랫폼을 제안한다. 제안하는 플랫폼에서는 단순한 게임을 즐김으로써 거부감 없이 광고를 받아들일 수 있고 간접적으로 스쳐지나가는 광고들보다 더욱 효율적으로 내용을 전달할 수 있다. 기존의 윈도우폼에서 발생하였던 드로잉 문제는 XNA 게임엔진을 사용함으로써 해결하였고 Facebook API를 사용하여 SNS와 연동할 수 있도록 제작하였다. 또한 랭킹 시스템의 도입으로 사용자의 흥미를 끄는 요소를 넣었고 사용자의 얼굴 이미지를 추출하여 스토리 라인에 추가하여 몰입 도를 높였다.

With the advancement of mobile web environments, identification and analysis of the user behavior play a significant role and remains a challenging task to implement with variations observed in the model. This paper presents an efficient method for mining optimized user behavior prediction model using genetic algorithm on mobile web structure. The framework of optimized user behavior prediction model integrates the temporary and permanent register information and is stored immediately in the form of integrated logs which have higher precision and minimize the time for determining user behavior. Then by applying the temporal characteristics, suitable time interval table is obtained by segmenting the logs. The suitable time interval table that split the huge data logs is obtained using genetic algorithm. Existing cluster based temporal mobile sequential arrangement provide efficiency without bringing down the accuracy but compromise precision during the prediction of user behavior. To efficiently discover the mobile users' behavior, prediction model is associated with region and requested services, a method called optimized user behavior Prediction Model using Genetic Algorithm (PM-GA) on mobile web structure is introduced. This paper also provides a technique called MAA during the increase in the number of models related to the region and requested services are observed. Based on our analysis, we content that PM-GA provides improved performance in terms of precision, number of mobile models generated, execution time and increasing the prediction accuracy. Experiments are conducted with different parameter on real dataset in mobile web environment. Analytical and empirical result offers an efficient and effective mining and prediction of user behavior prediction model on mobile web structure.

This paper discusses an optimization-based approach for the design of a product platform for industrial three-axis linear-type robots, which are widely used for handling objects in manufacturing lines. Since the operational specifications of these robots, such as operation speed, working distance and orientation, weight and shape of loads, etc., will vary for different applications, robotic system vendors must provide various types of robots efficiently and effectively to meet a range of market needs. A promising step toward this goal is the concept of a product platform, in which several key elements are commonly used across a series of products, which can then be customized for individual requirements. However the design of a product platform is more complicated than that of each product, due to the need to optimize the design across many products. This paper proposes an optimization-based fundamental framework toward the design of a product platform for industrial three-axis linear-type robots; this framework allows the solution of a complicated design problem and builds an optimal design method of fundamental features of robot frames that are commonly used for a wide range of robots. In this formulation, some key performance metrics of the robot are estimated by a reducedorder model which is configured with beam theory. A multi-objective optimization problem is formulated to represent the trade-offs among key design parameters using a weighted-sum form for a single product. This formulation is integrated into a mini-max type optimization problem across a series of robots as an optimal design formulation for the product platform. Some case studies of optimal platform design for industrial three-axis linear-type robots are presented to demonstrate the applications of a genetic algorithm to such mathematical models.

The purpose of this paper is to analyze media companies' editorial viewpoints regarding environmental issues. Not only do newspaper editorials provide a variety of environmental information, but also they make it possible for the public to form an opinion and to establish communication channels regarding environmental issues. With this in mind, this paper analyzes the changes in environmental reporting over the past two decades. The newspaper companies started writing more frequently about the environment from early 1980s. To show this, I analyzed environmental articles written in the six main news-paper companies: Chosun, Donga, Hangerae, Kyunghyang, Hankook, and Munwha from 1999 to 2004. For this study, the articles have been complied by using the Korean Integrated News Database System (KINDS). Also the data has been sorted according to year, subject, and ty the company of origin. The total number of the environmental articles posted on these six daily newspapers from 1999 to 2004 is 729 and these represent 2.59% of the total articles. Hankook-Ilbo was the company that handled the most of environmental articles followed by Hangerae, Munwha, Kyunghwang, Chosun, and Donga. The major topics of discussion were environmental development and water quality issues. The number of the environmental related articles increased in 1999 and 2000, but then decreased from 2001 to 2003. Again the number increased in 2004. Interestingly while the number of articles covering the environment increased from the 1980s and into the 1990s, the number of articles decreased from 1999 to 2004 as the post-IMF period seems to have suppressed interest in the ecological issues despite the economic growth that followed. With the change in media coverage people have begun to recognize environmental issues as having social impact. As a result the people have begun to take such issues more seriously and take more active role in effecting environmental policy. Thus it is important that the media presents it's stories in an object manner to insure that the public is properly informed.

Objectives: This research aimed to investigate Chinese clinical studies on the treatment of central post-stroke pain (CPSP) and thalamic syndrome after stroke with traditional herbal medicine (THM). Methods: Randomized controlled trials verifying the effects of herbal medicine on treating CPSP and thalamic syndrome after stroke were included in the study. Electrical and hand search were conducted in the China National Knowledge Infrastructure (CNKI), National Discovery for Science Leaders (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (Oasis) for CPSP and thalamic syndrome after stroke. A literature search was performed in the Chinese and Korean databases for papers published from January 1, 2010 to October 1, 2018. The selected literature was assessed by Cochrane's risk of bias. Results: Twelve reports on randomized controlled trials met the inclusion criteria from the 227 identified reports. Effective rate, comparison of visual analogy scale, present pain intensity, pain grading index, recurrence rate, follow-up, and a 36-item short form survey instrument were used to evaluate the treatments. The effective rate of the treatment group was significantly higher than that of the control group in all papers. Side effects occurred less frequently in the treatment group than in the western medicine control group. Conclusions: The treatment of CPSP and thalamic syndrome after stroke with THM was shown to be highly effective. Additional well-designed clinical trials are needed. This study can be used as a basis for further research on the treatment of CPSP and thalamic syndrome after stroke.

Objectives Osteoarthritis is hard to manage with both conventional and Korean medicine treatment. The core outcome set (COS) to demonstrate the effectiveness of Korean medicine treatment has not been established yet. We aimed to present preliminary data of COS by performing a literature review on the evaluation indices used in existing clinical research. Methods We examined the literature from 2000 to 2017 in two Korean electronic databases (Korea citation index and oriental medicine advanced searching integrated system) by searching for the following 3 terms 'total knee replacement (Korean)', 'total knee replacement,' and 'knee surgery.' We found 333 articles; among them, 50 duplicates were removed. Finally, we selected 160 articles after complete screening. We then extracted measured indices and clinical outcomes from the selected articles and categorized the relevant criteria. Results According to this study, the hospital for special surgery and knee society, range of movement angle, cross leg, Berg balance scale and balance ability, muscle strength, 6 minutes walking test, visual analogue scale, self-efficacy, the 12-item and 36-item short form survey and self-rated health status are the most commonly used outcomes of knee. Conclusions This study found that the several categories after total knee replacement (TKR) are being evaluated in the literature, and we were able to verify the most frequently used evaluation indices in these categories. The results of this study will be used to establish evaluation indices for the treatment of TKR in the future using Korean medicine.
