High-level synthesis generates a structural design that implements the given behavior and satisfies design constraints for area, performance, power consumption, packaging, testing and other criteria. Thus, high-level synthesis generates that register-transfer(RT) level structure from algorithm level description. High-level syntehsis consist of compiling, partitioning, scheduling This paper we study the partitioning process, and analysis the min-cut algorithm and simulated annealing algorithm.

정보 보안 기법 중 접근 제어 기법(Access Control)은 네트워크 기반 어플리케이션에 기본적인 정보 보안 틀을 제공한다. 아울러 권한 기반 접근 제어 기법(RBAC)으로 다양한 권한 요구 사항을 충족하는 네트워크 기반 어플리케이션의 운용이 가능하다. 그러나 Session Scope의 권한 기반 제어 기법으로 동적 페이지들에 대한 접근 제어를 설계 배포 하기는 어렵다. 관점 지향 프로그래밍(AOP)를 이용한 동적 권한 생성으로 Session Scope의 권한과 결합, Request Scope의 권한을 생성해 디자인 레벨에서의 유연한 접근 권한 설계 방법에 대해 제안하며, 구현 후 확인했다.

본 논문에서는 Unity 3D 엔진을 심층 분석하여 게임개발 교육현장에서의 유용성을 검토하였다. Unity 엔진을 이용하면 필드의 제작, 캐릭터 애니메이션 세팅, 스크립트 작성, Asset 관리, 레벨 디자인 등 많은 작업을 하나의 통합 환경에서 수행할 수 있다. 또한 컴파일 과정을 거치지 않아도 게임을 제작하는 도중 언제라도 실행해 볼 수 있기 때문에 개발에 걸리는 시간을 단축 할 수 있다. 본 연구의 초점은 게임 앱 설계 관련 프로젝트의 수행이나 교육용 게임 개발의 학습 모형을 제시하기 위한 과정이다.

보안은 비즈니스 성능에 있어 결정적인 문제점이지만 대게 보안은 비즈니스 프로세스 정의 후에 고려된다. 많은 보안 요구사항은 비즈니스 업무 레벨에 표현될 수 있다. 비즈니스 업무 모델은 그들이 소프트웨어 디자인과 창조를 위해 필요한 요구사항을 잡아낼 수 있기 때문에 소프트웨어 개발자를 위해 중요하다. 게다가 비즈니스 업무의 모델링은 지휘와 비즈니스 운영이 어떻게 개선되는지를 위한 중심이다. 이 논문은 활동 다이어그램을 통해서 안전한 비즈니스 업무를 모델링하기 위한 UML 2.0 확장을 설명한다. 전형적인 건강관리 업무에 이 접근을 적용할 것이다.

In this paper we tried to figure out the types of real money trade of game items, and in order to study it we examined the Leveling System of MMORPG which is a perfect competitive market and how the closed structure of the game economy emits real money trade. The over production of the MMORPG's leveling system which is a perfect competitive market increases the amount of currency in circulation and then induces arbitrage due to mudfalation inside the game. In order to improve this problem, there are three methods of resolutions. The first is stabling the game economy by spontaneous order among the game users, but this is much local than the artificial order which takes a long time and evokes discrepance in MMORPG competitive characteristic. Secondly, legislational regulations from the government could improve the problem, but this method doesn't grant information or services as non-material labor in which it couldn't follow up the developing speed of the game market. Finally, delicate modulation among game items by the designer isn't possible to constrain them, and there is a limited reason that it couldn't control the increase of currency which is the main factor of arbitrage.

The traffic classification is a preliminary and essential step for stable network service provision and efficient network resource management. While a number of classification methods have been introduced in literature, the payload signature-based classification method shows the highest performance in terms of accuracy, completeness, and practicality. However, the payload signature-based method has a significant drawback in high-speed network environment that the processing speed is much slower than other classification method such as header-based and statistical methods. In this paper, We describes various design options to improve the processing speed of traffic classification in design of a payload signature based classification system and describes our selections on the development of our traffic classification system. Also the feasibility of our selection was proved through experimental evaluation on our campus traffic trace.

This study aimed to understand the effects on the improvement of hair texture by producing a hair texture improvement agent with milk thistle oil, and then applying it to the damaged hair. Each sample before and after application was measured. To understand the effects on the improvement of hair texture, the tensile strength, absorbance with the use of methylene blue, and gloss were measured. In the results of measuring the tensile strength to understand the effects on the improvement of hair texture, In the results of analyzing the absorbance with the use of methylene blue, the value after application was decreased than the value before application. In the results of measuring the gloss, none of the samples showed huge differences. In the results of this study, the milk thistle oil showed the effects on the texture improvement of damaged hair.

Since the scaling-down of IC devices has been reached to their physical limitations, several innovative packaging technologies such as 3D packaging, embedded packaging, and fan-out wafer level packaging (FOWLP) are actively studied. In this study the fabrication of organic-inorganic dielectric material was evaluated for the use of multi-structured redistribution layers (RDL) in FOWLP. Compared to current organic dielectrics such as PI or PBO an organic-inorganic hybrid dielectric called polysilsesquioxane (PSSQ) can improve mechanical, thermal, and electrical stabilities. polysilsesquioxane has also an excellent advantage of simultaneous curing and patterning through UV exposure. The polysilsesquioxane samples were fabricated by spin-coating on 6-inch Si wafer followed by pre-baking and UV exposure. With the 10 minutes of UV exposure polysilsesquioxane was fully cured and showed $2{\mu}m$ line-pattern formation. And the dielectric constant of cured polysilsesquioxane dielectrics was ranged from 2.0 to 2.4. It has been demonstrated that polysilsesquioxane dielectric can be patterned and cured by UV exposure alone without a high temperature curing process.

With the arrival of the 21th century, the management environments such as the knowledge system, information system, and technology system surrounding small and medium enterprises are being rapidly changed. These rapidly changing the environment of enterprises like the above can be thought rather profitable for the elastic and resiling medium enterprises than large enterprises. Additionally, these environments are recognized as the management circumstances which provide with the change by which medium enterprises equipped with the trustworthy creativity in the 21th century are able to become the main player of the industrial development. The position and role of medium enterprises in the national economical system are very important. The execution of the local autonomy system and the policy to activate the local economy will generally enlarge the power of medium enterprises which are based on the concerned local society more ant more. But, by the standpoint of designer, it is pointed out that there is the problem that the effective application means or the availability of the industrial design was not sufficiently recognized or understood by the manager in enterprises. Notwithstanding the above problem, a lot of domestic small and medium enterprises became to apply the industrial design as the means for improving the competitiveness of their own products in the relatively short time powered by the governmental policy, and moreover both of the concerned partners(the manager and industrial designer) had the opportunity to newly recognize the industrial design and evaluate the availability or problem of the industrial design in the actual aspect. This event means very important change. With the understanding on the above situation, the purpose of this study is to recognize whether the design is strategically applied in the management level of domestic small and medium enterprises, whether the strategical establishment of the design management is performed without any problem, whether the field designer and CEO are well recognizing the design management and what their recognition level is in order to seek the new solution for plenty of problems. Therefore, the actual proof analysis was performed for the field designer and management CEO of small and medium enterprises with the questionnaire survey and direct interview method to understand the actuality of small and medium enterprises.
