본 논문에서 온라인 쇼핑몰에 적용을 목적으로 2차원 이미지에 기반한 가상 의상 착용 알고리즘을 설계하고 개발하였다. 기존의 가상착용 시스템은 3차원 의상 및 사용자 정보에 기반하여 비용과 시간이 많이 들어가는 문제를 가지고 있다. 본 시스템은 최근 급격히 발전된 딥러닝기술과 컴퓨터 그래픽스 기술을 활용한다. 우선, 패션영상을 시멘틱 분할 네트워크를 사용하여 옷과 신체를 영상분할하고, 자세 네트워크를 사용하여 의상과 사용자의 골격정보를 확보한다. 이 두 가지 정보를 바탕으로 의상의 골격위치와 사용자의 골격위치를 일치시킴으로서 변형에 필요한 변수를 확보하고 이를 바탕으로 영상 변형을 하여 가상착용을 수행한다. 실험결과 단순한 기하형태의 옷과 선 자세를 유지하는 패션사진과 사용자사진의 경우 만족스러운 변형 결과를 얻을 수 있었으나 다양한 의상의 형태나 자세를 갖는 경우 원만한 착용결과를 얻을 수 없었다. 완벽한 시스템은 존재할 수 없으므로 현재 기술로 적용 가능한 의상의 범위와 문제 상황을 자세히 분석하여. 이를 바탕으로 추후 연구를 방향을 설정할 수 있도록 하였다.

GSA (Gaming Standards Association)’s S2S (System to System) standard provides harmonizing protocol between any gaming and non-gaming host systems in the casino back office and Casino business area. Its technical details and implementation is rarely open to the academy and public. This paper discuss our ongoing implementation of S2S protocol engine and systems, which is, to our knowledge, the first case in Korea. Our design leverages open source technologies such as Linux, Python, Django, Tornado, JQuery, and lxml. Describing the architecture and an application scenarios of ‘PlayerInfo’ class, we demonstrate how the open source technology can be utilized in the S2S system design.

The international casino game industry has adopted G2S (game to systems) protocol for the future communication standards between slot machines and gaming hosts. G2S protocol uses the internet protocols and XML message format. Not simply G2S protocol replaces the SAS protocol currently in use but with many limitations, but provides diverse application and business chances to the casino industry. In this paper, we introduce the overview of technical features of G2S system, and describe our design and implementation experience of core G2S protocol engine for slot machine devices. The G2S engine provides key protocol stack of G2S (HTTP, XML, and SOAP) and runtime services, using open source softwares and custom classes. The protocol compatibility of the implemented G2S engine is confirmed against an openG2S host software contributed by IGT. Also the measured memory size and perfroamcne is compact enough for typical slot machine hardware specification.

For the recent 5-6 years, the ratio of smart phone users in South Korea has increased to over 65% of cellular subscribers and half of all population. While smartphones have given enormous convenience to our lives, pathological use of smartphones has brought a new mental health concern among the community. Therefore, huge interest sheds on the studies on the cause analysis and treatment of smartphone addiction. However, the traditional clinic approach based survey and interview has serious drawbacks of its subjectivity and inability of continual monitoring and treatment. In this paper, SAMS (smartphone addiction management system) is presented, which monitors the application usage pattern, provides statistical analysis, and policy-based usage intervention. A trail test is performed for checking he reliability and efficacy of SAMS in smartphone addiction research, and some analysis on the collected data are done: daily use count, not daily use time, has strong influence on smartphone addiction: CC=0.62 and CC =0.00 for the correlation coefficients of counts and times with total survey score, and p = 0.047 and p = 0.507 for t-test analysis of contrast group.

Since the advent of smart phones in 2007, the population of smart phone user has been increasing at stunning rate in Korea. In spite of many benefits such as full internet access, location based service, and easy installation of new applications, many social and medical researches have been reported the concern of overuse of smart phones, especially for teenagers on game and internet addiction. However, most of studies are based on the survey research, so often questioned to be limited number of sample and subjective, which can be overcome by evident-based study. The paper presents a pilot development of Google Android app that provides the 24-hour-measured application usage pattern of smart phone users. A requirement study performed with medical doctors and phycologists are discussed and the key technical and application issues are discussed and their solutions are presented. The system is designed to be extensible so that social network and additional service can be applied based on the user. The measured data is expected to be used for study the cause and treatment of game and internet addiction for teenagers and adults.

The international and domestic revenue keep growing constantly, and nowadays the international casino game industry is getting upgraded utilizing IT technology. In contrast, due to many constraints and limitations, Korean IT society has not paid attention to the casino IT area. Slot machine is one of popular gaming systems in the casino. In this paper, we present our design and implementation of protocol analysis system for SAS 6.0 protocol. Slot machine accounting system (SAS) is an international standards protocol and provides auditing, management, and additional service for slot machines. Our protocol analysis system design experience provide in-depth understanding on slot machine and its accounting requirement than a simple conceptual introduction of protocol. Also, the key difficulties of SAS protocol implementation and performance requirement is examined. Our system successfully works in small portable embedded system and showed its benefits, showing benefits for debugging and reverse-engineer a real work problem with commercial system. The engine of the analysis software will be the base of real SMIB (slot machine interface board) system for commercial use.

Frying is the most popular cooking style used in food service institutions in Korea because fried dishes are well accepted by students. However, trans fat contents reduction have recently been required in many foods for health reasons Therefore, alternatives to frying such as oven baking or roasting are being used in many institutions. Steam convection ovens provide dry heat as well as steam so that they can be used to make a wide variety of Korean dishes. In this study, a menu acceptance test was conducted over 2 weeks. Pork, chicken, fish and potato dishes cooked by conventional cooking methods were served for 4 successive days, after which the same dishes were prepared using the oven. Overall, 322 junior high school students evaluated the traditionally cooked foods, while 316 evaluated the oven cooked foods. Comparison of the foods prepared using both methods only revealed a significant difference in the acceptability of foods on the fish menu (p<0.05). Specifically, the acceptance of fried fish was higher than that of the oven baked fish. Additionally, overall acceptance of the menu by males was higher than the acceptance by girls. Furthermore, students who had the preference for special ingredients showed a higher menu acceptance for the menu cooked with those ingredients. On average, approximately 25% of the meal was not consumed and left as plate waste. The portion of the fried fish not consumed was smaller than that of the oven cooked fish, but the portion not consumed did not vary based on cooking method for any other foods evaluated. Overall, it is expected that the oven cooking method will be a good substitute for frying or other cooking method for traditional Korean dishes.

Background: Leonurine is a the aerial part of Leonurus japonicus Houttuyn, which has been used as a traditional medicines and is registered in the Korean Pharmacopoeia.Methods and Results:In the present study we performed a heavy metals and thin layer chromatography and measured loss on drying, as well as the contents of total ash, acid-insoluble ash, ethanol soluble compounds, and leonurine, using 15 domestically collected L. japonicus samples. The methods were performed according to the ‘crude drugs test of the general test, processes and apparatus’, published by MFDS, Korea (2014). The purity test (heavy metals) indicated that levels of Pb and Hg were 0.35 - 3.64, and 0.001 ppm, respectively, whereas the levels of As and Cd were undetectable, and stachydrine was identified by thin layer chromatography (Rf : 0.15). We found that 5.93 - 10.62% (average: 8.58 ± 1.8%) of the sample mass was lost during drying, and the contents of total ash, acid-insoluble ash, ethanol soluble compounds, and leonurine were 7.87 - 10.84% (average: 9.62 ± 0.82%), 0.99 - 1.76% (average: 1.38 ± 0.24%), 16.70 - 23.11% (average: 19.49 ± 2.14%) and 0.04 - 0.17% (average: 0.11 ± 0.04%) respectively. In addition, HPLC profiling detected leonurine (5.94 min), rutin (16.43 min) and myricetin (26.78 min).Conclusions:We hope that this the rusult of the present study will contribute to the standardization and quality control of Korean herbal medicines.
