Objective : This study was carried out to analyze the trends of Acne related articles that have been published in the Journal of Korean Medicine Ophthalmology, Otolaryngology & Dermatology(JKOOD). Method : We studied 29 research papers relevant to Acne that published in JKOOD from 1998 to 2013. All the paper were classified into three categories; original article, review article and case report. We sub-classified the original articles into three categories; descriptive study, analytic study and experimental study. We analyzed the case report according to various types of treatment. Results : 1. The number of searched journals is 29 papers; 17 original ordicles, 4 review articles, 8 case reports. 2. Classification of 17 original articles into three categories; 10 experimental studies, 7 descriptive studies, 0 analytic study. 3. Method of Evaluation; Korean Acne Grading System(KAGS) is used frequently in descriptive studies and experimental studies. 4. Treatment in Case reports; 7 Case reports used External medical treatments. Conclusions : It is needed to develop the methods of grading system in acne related to Oriental medicine to obtain objectivity of studies. The number of analytic study, clinical trial and experimental study is need to increase.

The Internet of Things (IoT) shopping environment can provide benefits and risks to consumers, including shopping convenience and invasion of consumer rights, respectively. We experimentally tested whether exposure to information regarding the benefits and risks of IoT shopping would elicit changes to consumer perceptions of the importance of shopping convenience and rights to information, as well as shopping intention among young online shopping consumers. The participants (N=218) were randomly assigned into one of two experimental conditions. The control group was exposed to a news article and a video emphasizing the shopping convenience of the Amazon Dash Button service, while the experimental group was exposed to the same news article and video provided to the control group, along with a news article about the judgment of the Munich court that the Dash Button violates German consumer law. We found an interaction effect of experimental condition and time on changes to the perceived importance of shopping convenience and shopping intention. The changes to the perceived relative importance of shopping convenience to consumer rights to information from pre- to post-manipulation differed significantly between the two experimental groups. The results of this study emphasize the importance of providing information on both the benefits and risks of IoT shopping. This was the first experimental study to examine the possibility of the invasion of consumer rights to information in the IoT shopping environment. This study urges researchers, marketers, and policy makers to focus more on consumer rights to information in the newly coming IoT shopping environment.

The purpose of this article is to present the environmental enrichment(EE) method used to improve the functional recovery and change of brain plastic in animal experimental models of stroke. In animal experimental models of stroke, the environmental enrichment is effective in altering the morphological, biochemical and behavioral characteristics of the brain and thereby improving the functional outcomes. In this review article, we address the effects of EE in achieving a functional recovery in animal experimental models of stroke, thus attempting to describe them in patients with stroke from both occupational and rehabilitation perspectives.

As a result of the study on a number of the works, published in Russia, the methodical aspects of experimental improvement on working capacity of LRE (Liquid Rocket Engine) are reviewed. In the article, on the basis of the experience of Russia and USA, the special features of experimental improvement on working capacity of LRE and the methods of its rational implementation formulated. The organizational and technical solutions of experimental improvement on working capacity of LRE for achieving the required level of the reliability and decreasing the material expenditures are presented in the article. These suggested solutions can be used for the development of LRE.

Wikipedia infoboxes have emerged as an important structured information source on the web. To compose infobox for an article, considerable amount of manual effort is required from an author. Due to this manual involvement, infobox suffers from inconsistency, data heterogeneity, incompleteness, schema drift etc. Prior works attempted to solve those problems by generating infobox automatically based on the corresponding article text. However, there are many articles in Wikipedia that do not have enough text content to generate infobox. In this paper, we present an automated approach to generate infobox for movie domain of Wikipedia by extracting information from several sources of the web instead of relying on article text only. The proposed methodology has been developed using semantic relations of article content and available semi-structured information of the web. It processes the article text through some classification processes to identify the template from the large pool of template list. Finally, it extracts the information for the corresponding template attributes from web and thus generates infobox. Through a comprehensive experimental evaluation the proposed scheme was demonstrated as an effective and efficient approach to generate Wikipedia infobox.

This study is to verify effects of banner advertising by context effect in web contents. For this, it analyzed the effects of banner advertising by association of internet article's contents, emotion, difficulty of article and the level of involvement. According to the result of experimental design, banner advertising effects by context effects of web contents were high in the following cases; in the case when the contents were highly associated with banner advertising; in the case when the positive emotions were formed by the internet article; in the case when the difficultly of article was low; and in the case when consumer's involvement was high. And also, when the contents were highly associated with the advertising, the content effects of web contents were high even in the case when the negative emotions were formed; in the case when the difficulty of article was high; and consumer's involvement was low.

Sinusitis is a common medical problem in children. The prevalence of penicillin-resistant S. pneumoniae infection has been increased during the last decade. The medical management is based on the choice of antimicrobial agents. This article reviews current literatures on the management of acute bacterial sinusitis and chronic sinusitis, with an emphasis on penicillin-resistant S. pneumoniae infection. This article also explores the potential pathophysiologic mechanisms of chronic sinusitis.

The increasing use of nano-positioners in a wide variety of laboratory and industrial applications has created a need for nano-mechatronics education in all engineering disciplines. The subject of nano-mechatronics is broad and interdisciplinary. This article focuses on the way nano-mechatronics is taught in department of mechanical engineering at Korea Advanced Institute of Science and Technology (KAIST). As one model of nano-positioning systems, design and experimental methodology is presented in this article. For design phase, the stiffness and resonant frequencies are found analytically and verified by using a commercial finite element analysis program. Next, for experimental phase, various tests are performed to access the performances of the designed nano-positioner, for example, sine-tracking, multi-step response and travel-range check etc. Finally, the definition of 'separation frequency' is described and some comments are discussed.

A significant new technique in the dsvelopment of micro-wave circuits is the process of untilization of coupled lines in the transverse electro-magnetic field. The bases for this technique are the application of even-and odd-mode characteristic impedances of the transmission line. This article describes the properties of directional couplers and explains a prccfdure usrd to design micro-strip directional couplers with the aid of the computer. The article also describes the experimental results obtained from seven microstrip couplers, which were built to verify the computer program and the approximate solutions. It can be seen that in cases at X-band where couplings of 10 to 20dB are required, the computer program and approximate solutions will produce good results.
