지능화된 안드로이드 악성코드는 안티바이러스가 탐지하기 어렵도록 악성행위를 숨기기 위하여 다양한 분석 회피 기법을 적용하고 있다. 악성코드는 악성행위를 숨기기 위하여 백그라운드에서 동작하는 컴포넌트를 주로 활용하고, 자동화된 스크립트로 악성 앱을 실행할 수 없도록 activity-alias 기능으로 실행을 방해하고, 악성행위가 발견되는 것을 막기 위해 logcat의 로그를 삭제하는 등 지능화되어간다. 악성코드의 숨겨진 컴포넌트는 기존 정적 분석 도구로 추출하기 어려우며, 기존 동적 분석을 통한 연구는 컴포넌트를 일부만 실행하기 때문에 분석 결과를 충분히 제공하지 못한다는 문제점을 지닌다. 본 논문에서는 이러한 지능화된 악성코드의 동적 분석 성공률을 증가시키기 위한 시스템을 설계하고 구현하였다. 제안하는 분석 시스템은 악성코드에서 숨겨진 컴포넌트를 추출하고, 서비스와 같은 백그라운드 컴포넌트인 실행시키며, 앱의 모든 인텐트 이벤트를 브로드캐스트한다. 또한, 분석 시스템의 로그를 앱이 삭제할 수 없도록 logcat을 수정하고 이를 이용한 로깅 시스템을 구현하였다. 실험 결과 본 논문에서 제안한 시스템을 기존의 컨테이너 기반 동적 분석 플랫폼과 비교하였을 때, 악성코드 구동률이 70.9%에서 89.6%로 향상된 기능을 보였다.

The purpose of this study is to present the use of traditional culture and the direction of various fashion designs by developing and producing contemporary fashion designs on the Muslim costumes of the Chinese Hui minority. Based on research methods, the cultural background was investigated and the design characteristics were summarized. Based on the results of this survey, 4 sets of women's fashion were designed. The design intent was to feature Muslim traditional costumes and to adopt a functional contemporary design. The conclusions of this study are as follows. First, simple and indecisive clothing shows the innocent and good side of the congregation. In this study, traditional dresses were used to make use of the simple silhouette and color, and to create a contemporary atmosphere, various materials, such as wool, glossy industrial complex, lace, and fur were used to create a modern sense design by adding diversity to the simple silhouette. Second, the biggest feature of the regimented Muslim costume focuses on a head cover and suggests a contemporary sense of hood improvement, and a design that can be used with two sides. These hooded head covers can provide fashion and diversity and can be proposed as functional. Third, contemporary Muslim fashion is gaining global attention and it is possible to develop various fashion designs based on traditional motifs. This study was able to increase the feminine image by changing the solemnity of the communal dress without discarding the foundation of the traditional religious culture based on the daily dress of the people.

One of the most considerate phenomena of the era of the Fourth Industrial Revolution is the use of digital devices. Digitalization is rapidly advancing through all areas of industry and life. Customer journey with digitalization is looking totally different from previous customer journey. The research targets were users of fashion, automobiles, cosmetics and online shopping malls. We analyzed 300 people for each valid questionnaire. The results of the study are as follows. First, it has been proven that digital experience affects positive (+) impact on purchasing intention and positive (+) impact on recommending intention and negative impact (-) on switching intent and subsequently affects positive impact (+) to purchase and incase of switching intent, negative impact (-) to purchase. Unlike traditional methods such as SPC(Service Profit Chain), the Digital experience to Purchase process Chain (DPC) has been identified to be suitable in the digital age. Second, the digital satisfied group (5 score-very satisfaction) has shown same result as above. However the digital neutral group (even though 4 score- satisfaction in five-point scale), specially in a highly competitive industry, has different from the satisfied group and 3 score-normal is same as dissatisfied group. It means that this group is that If there is a high level of attractiveness of substitute goods, there is a high possibility of switching them. It has supported Jones and Sasser [1995] that there have been two types of loyalty of true long-term loyalty and what we call false loyalty in the highly competitive industry zone which is commoditization or low differentiation, many substitutes, low cost of switching. Identifying true loyalty and false loyalty is crucial to establishing a customer experience strategy. it is necessary to actively utilize long-term digital experiences strategy to increase the total satisfaction of digital experience through all of customer purchasing journey in order to enhance the digital customer experience. It is difficult to see the effect as a one-time event. It should be scaled over the entire customer purchase process over a long period of time, which can positively affect purchase intention, recommendation intention, and conversion intention. This is also why it is difficult for second-runners to overtake first-runners in a short period.

Objectives: Among many new drugs that are under investigation with intent to treat cancer, oral kinase inhibitors are proven to be effective in numerous clinical trials and easy to administer. Due to these advantages the use of oral kinase inhibitors is increasing. Oral kinase inhibitors are metabolized by CYP450 which can result either increase of adverse effect or decrease of drug effect by drug interaction when used concurrently with other agents. In this research, the medication records of patients on oral kinase inhibitors from Oct. 2010 to Nov. 2011 were reviewed to investigate potential drug interactions. Methods: From Oct. 2010 to Nov. 2011, cancer patients in Inha University Hospital who took oral kinase inhibitors more than once were included. The patients' medication records were reviewed to list out concurrent medications that have interaction potential with oral kinase inhibitors, the frequency of concurrent use, and the severity of interaction result using Micromedex$^{(R)}$ and Lexicomp-online$^{(R)}$ as references. Results: As a result, 90 cases of drug with interaction potential were prescribed by Micromedex$^{(R)}$ and 179 cases by Lexicomp-online$^{(R)}$ data. In case of severity, 33.3% by Micromedex$^{(R)}$ and 26.3% by Lexicomp-online$^{(R)}$ were categorized as Major and 65.6% by Micromedex$^{(R)}$ and 72.6% by Lexicomp-online$^{(R)}$ as Moderate. The number of adverse events was 92 cases which 58.7% were on skin and 19.6% on Gastro-intestinal tract. Conclusions: Considerable number of drug with interaction potential was used though each oral kinase inhibitors showed differences in extent. Hence there exists the risk of drug interaction in patients taking oral kinase inhibitors with other drugs.

The use of agent paradigm in today's applications is hampered by the security concerns of agents and hosts alike. The agents require the presence of a secure and trusted execution environment; while hosts aim at preventing the execution of potentially malicious code. In general, hosts support the migration of agents through the provision of an agent server and managing the activities of arriving agents on the host. Numerous studies have been conducted to address the security concerns present in the mobile agent paradigm with a strong focus on the theoretical aspect of the problem. Various proposals in Intrusion Detection Systems aim at securing hosts in traditional client-server execution environments. The use of such proposals to address the security of agent hosts is not desirable since migrating agents typically execute on hosts as a separate thread of the agent server process. Agent servers are open to the execution of virtually any migrating agent; thus the intent or tasks of such agents cannot be known a priori. It is also conceivable that migrating agents may wish to hide their intentions from agent servers. In light of these observations, this work attempts to bridge the gap from theory to practice by analyzing the security mechanisms available in Aglet. We lay the foundation for implementation of application specific protocols dotted with access control, secured communication and ability to detect tampering of agent data. As agents exists in a distributed environment, our proposal also introduces a novel security framework to address the security concerns of hosts through collaboration and pattern matching even in the presence of differing views of the system. The introduced framework has been implemented on the Aglet platform and evaluated in terms of accuracy, false positive, and false negative rates along with its performance strain on the system.

Background and objective: This study was conducted to obtain empirical data for deriving necessary items for the creation and management of gardens in urban agricultural parks while maintaining the publicness of the place by examining the difference in perception among park visitors about the gardens in the public parks. Methods: A survey was conducted on users of urban agricultural parks in 6 locations and 113 copies of the questionnaire were collected. After understanding the demographic characteristics and the current use of the garden, we identified the importance of the necessary items for the public gardens. Results: 108 subjects(95.6%) responded that gardens are needed in urban parks, for psychological and emotional health (26.2%) and for interaction and friendship with family and neighbors(23.2%). For use of garden crops, most were private sales(96 subjects, 64.4%), and both sales preferred to partially donate their crops. Most used communal gardens operated by public institutions(30.1%). It was found that 96.4% of the respondents were satisfied with gardening activities, and 107(94.7%) of them showed their intention to participate in the gardening in the future. The Kaiser Meyer Olkin value was .848 and the significance level was .001, proving the validity of factor analysis. The factors were named composition elements(Factor 1), management items(Factor 2), convenience elements(Factor 3), and operational facilities(Factor 4). In the survey on the creation and management of gardens in urban agricultural parks, there were no statistically significant differences, but all items had correlations. Conclusion: The results have reflected the needs of actual users in establishing the plans to operate urban gardens, thereby having great utility value as the basic data for continuous garden management. Further research can be conducted to derive detailed elements that can guarantee sustainability of urban gardens and suggest high-quality data for management of gardens in urban agricultural parks.
