본 연구는 스트레처블 디스플레이 기술이 적용된 모바일 기기의 화면 변화에 대응 가능한 보안 키패드 구조를 제안하였다. 이를 위해 우리는 현재의 리지드 폼 팩터 기반 스마트폰에 적용된 인증기법들을 스트레처블 디스플레이 기술의 전 단계에 해당하는 롤러블 및 벤더블 디스플레이 기술이 적용된 스마트폰에 적용된 인증기법들과 비교 분석하였다. 이 분석 결과를 바탕으로 우리는 스트레처블 디스플레이가 적용될 모바일 응용제품 규격인 스마트 월렛, 멀티태스킹, 스크린 확장 및 미디어 시청, 게임 및 엔터테인먼트용 폼팩터 구조에서 발생할 수 있는 사용자 편의성 문제와 보안 안전성 문제를 도출하였고 이에 대응하는 보안 키패드 구조를 제안하였다. 제안하는 보안 키패드 구조는 기존의 리지드 디스플레이 기반 폼 팩터 및 롤러블, 벤더블 디스플레이 기반 폼 팩터의 스마트폰 환경에 적용된 구조에 비해 더욱 향상된 사용자 편의성 및 보안 안전성을 제공한다.

The layered multi-barrier defense situation against penetrating enemy threat is analytically modeled towards minimizing the penetration probability. Each layer is characterized by probability of detection and probability of kill given detection. The two capabilities are assumed independent. Detection in a layer, however, affects detection performance in subsequent layers. The following three models were formulated and investigated: (1) 'Model A' permits increase of detection performance in only the next barrier, (2) 'Model B' permits the increase in all subsequent barriers linearly, and (3) 'Model C' expresses the increase in an asymptotic exponential way. The best and the worst barrier combinations are determined through model exercise and model performances are compared through sensitivity analysis for the 'intensification factor.'

In this paper, we proposed new solution procedure of the air defense missile allocation problem. In order to find the optimal location of missile, we formulated a simple mathematical model maximizing the kill probability of enemy air threat including aircraft and missile. To find the Kill probability, we developed a new procedure using actual experimental data in the mathematical model. Actual experimental data mean real characteristic factor, which was acquired when the missile had been developed through missile fire experiment. The result of this study can offer practical solution for missile allocation and the methodology in this study can be used to the decision making for the optimal military facility allocation.

In transportation network problems, it is often desirable to select multiple number of the shortect paths. On problems of finding these paths, algorithms have been developed to choose single shortest path, k-shortest paths and k-shortest paths via p-specified nodes in a network. These problems consider the time as the main factor. In wartime, we must consider availability as well as time to determine the shortest transportation path, since we must take into account enemy's threat. Therefore, this paper addresses the problem of finding the shortest transportation path considering both time and availability. To accomplish the objective of this study, values of k-shortest paths are computed using the algorithm for finding the k-shortest paths. Then availabilties of those paths are computed through simulation considering factors such as rates of suffering attack, damage and repair rates of the paths. An optimal path is selected using any one of the four decision rules that combine the value and availability of a path.

The damages from DDoS attacks are increasing as DDoS attacks are taking various forms. This has resulted not only in decreased reliability of organizations and corporations but also in the threat of national security. Organizations and corporations are making significant efforts in developing a system through which they can appropriately correspond to DDoS attacks. However, the studies on objective index for evaluating the performance of DDoS correspondence are lacking. The majority of the existing studies have been on the information protection & management system on a large scale. Accordingly, the scope of this thesis will be limited to DDoS correspondence to propose correspondence index for quantitatively measuring and managing them. The statistical techniques such as SMART technique and factor analysis will be utilized accordingly.

Attempts to develop drugs, specific for cancer cells, are dealt here according to the intended cell-target. While many target specific drugs were developed, they reach only moderate successes in clinics for reasons, such as, delivery problem, lack of in vivo efficacy or toxicity. However, recent efforts focusing on the diversity of tyrosine kinases, participating in cell-signal transduction, brought fruit. The first such drug, Givec, approved by the USFDA recently, is used in clinics with great success to threat CML. The drug inhibits tyrosin kinase of bcr-abl, c-abl and v-abl. Work is progressing on other tyrosin kinase inhibitors and on other type of specific cancer cell signal protein inhibitors. These efforts are hoped to yield better cures for cancer in the near future.

Inappropriate antibiotic use is the most important factor causing increased bacterial resistance to antibiotics, thus affecting patient outcomes. Multidrug-resistant bacteria have become a serious public health threat, causing significant morbidity and mortality worldwide. In Korea, the burden of antibiotic-resistant bacteria has become an important public health issue. There is increasing evidence of overuse and misuse of antibiotics in Korea, as observed in cohorts with large sample sizes. Antibiotic use among children should receive particular attention because of the frequency of community-associated infections among this population and the elevated risk of transmission. Recent studies from Korea have demonstrated that the use of broad-spectrum antibiotics, either for inpatient or outpatient treatment, has increased among many age groups, especially children. In this review, we aim to describe the patterns of antibiotic prescription and evaluate recent trends in antibiotic use among children. Coordinated efforts toward communication and education in order to address misunderstandings regarding antibiotic use, involving interprofessional antimicrobial stewardship programs, are required in the near future.

최근 아파트의 월패드 해킹 사건과 같이 사물인터넷의 보안이 매우 심각한 상황이다. 사물인터넷은 자동화된 데이터 수집, 분석, 의사결정으로 효율성과 생산성 향상하고, 실시간으로 모니터링이 가능하면서 저비용으로 개발이 가능하다. 그리고 현재 인공 지능, 빅 데이터 및 클라우드 컴퓨팅 등 다양한 기술과 융합이 가능해 더욱 발전할 전망을 가지고 있다. 그러나 활용 범위가 갈수록 방대해지지만 현재 기술력으론 완벽한 보안을 실현하기가 어려운 것이 현실이다. 그리고 해킹의 대부분 직접적인 피해 당사자인 소비자들은 스마트홈이 주는 편의에 대해서만 알 뿐 보안 위협요소에는 잘 알지 못한다. 스마트홈의 보급이 빨라지고 있지만 정부 및 제조사에서 아직 스마트홈 보안에 관련한 홍보 및 교육이 따라가지 못하기 때문이다. 이러한 점을 보완하기 위해 본 논문에선 스마트홈의 보안 실태와 보안 요구사항에 대해서 다양한 방안을 살펴보고자 한다.

This study reexamines a covert factor of the colonization of Myanmar kingdom, drawing on the case of Myingyun-MyingonDaing Rebellion broke out in 1866. It criticizes that existing discussions on the downfall of the Konbaung dynasty are preoccupied with post-colonialism. These researches were focus on macro level and pointed out the imperialist stratagem and many scholars concluded for the down fall of Konbaung Dynasty that the wave of Imperialism as Sunami hit from Europe to Asia so that Myanmar could not stand as feudal society and down fall Konbaung Dynasty. All of events and comments were quite true but it is necessary to examine carefully past events. There were many controversial facts about third Anglo-Myanmar war. This paper has pointed out the Kings Mindon's false political strategic due to the lack of awareness on external threat with the giving the best example of Myingun-MyingonDaing rebellion.

This study is aimed at using the grasped problems of protected areas in Korea as the basic data for management planning and system improvement of protected areas by grasping realistic problems through the interview with the persons in charge on the basis of general problems of domestic protected areas. To this end, this study deducted major problems in urgent need of improvement, and improvement direction through the survey of the persons in charge of protected areas. This study result is as follows: The major problems, which should be preferentially improved, were found to be shortages of management infrastructure, cooperation between interested parties, and threat factors in protected areas, etc. Such problems are interconnected with each other, thus coming up complexly; therefore, it's necessary to make a comprehensive approach to the problems after confirming the causal relationship of the identified problems. In addition, for the purpose of effective management of a protected area, it's necessary to implement priority management of major problems through different management intensity from the planning phase. Also, it's important to enhance the effectiveness of planning by considering a possible potential threat factor in the outside of protected areas, and referring to the contents of the development plan for the relevant area in time of management planning. Lastly, there is the need for systematic improvement of an institution through thorough status review of the actual state of management planning fulfillment in order to increase the effectiveness of planning in a follow-up study hereafter.
