색소는 천연 또는 합성색소가 있으며, 식품, 화장품 및 의류염색용 등 다양한 분야에서 사용되고 있다. 합성색소는 착색률이 높고 안정하며 가격이 저렴하여 천연색소를 대신하여 광범위하게 사용되어 왔으나 발암성과 인체에 독성을 갖는 등 안전성문제가 제기됨에 따라 그 사용이 엄격히 규제되어 왔다. 이러한 합성색소의 안전상 문제와 건강지향 생활패턴으로 천연제품 지향 소비 트렌드는 더욱 더 고조되어 최근 식품 색소에 이용되고 있는 천연색소 시장이 크게 신장하고 있다. 이에 본문에서는 천연색소 일반적인 기술 및 국내 기술동향을 알아보고자 한다.

Java provides support for Web, concurrent programming, safety, portability, and GUI, so there is a steady increase in the number of Java users. Java is based on the object-oriented concepts such as classes, instances, encapsulation, inheritance, and polymorphism. However the JVM(Java Virtual Machine) hides most of the phenomena related to the concepts. This is why most of Java users have much difficulty in learning and using Java. As a solution to the problem, I have developed a tool Alpha that visualizes the phenomena occurred in the JVM from the standpoint of the concepts and will describe the design and features of the tool in this paper. For practicality and extendability Alpha has an MVC(Model-View-Controller) architecture and visualizes the phenomena such as object instantiations, method invocations, field accesses, cross-references among objects, and execution flows of threads in the various ways according to the levels and purposes of the users.

Service Oriented Architecture (SOA), which supports various features such as interoperability and reusability of IT resources, comes into the spotlight as an effective approach for adapting new business environmental changes. SOA, however, has some problems including the high realization complexity and low Return on Investment (ROI). To solve these problems, Web Oriented Architecture (WOA) has gained attention. However, it also has some drawbacks about security concerns and unstable message transmissions. In this paper, we design a novel integrated architecture that classifies services into inside and outside ones and applies SOA for the former and WOA for the latter, respectively. By converging the advantages of SOA and WOA simultaneously, the proposed architecture becomes more simple and service-oriented, and can satisfy diverse requirements of customers. The usefulness evaluation of the proposed architecture is conducted through the Analytic Hierarchy Process (AHP) scheme.

An object-oriented system is organized by a set of interacting objects and the system behavior is represented by the cooperating interaction bet ween objects. The characteristics of object-oriented software. such as inheritance and polymorphism, increase the difficulty of the object-oriented software testing. At running time of a program, one call from a member function can bind to other member functions because of the dynamic characteristics such as concurrence, dynamic binding and interaction. Therefore, there need the research about considering the characteristics of object-oriented software and concurrently testing the interaction between objects. In this paper, we propose the techniques as follows. First, we construct a flattened state chart diagram by considering the inheritance and polymorphism. Next, we model the system with CPN(Colored Petri Net) that usually is applying the system modeling and simulation. Last, we propose a test case generation techniques for testing the interaction between objects in object-oriented software by applying a Design/CPN tool.

This paper examines if China' each province.city manages its organization well after China's WTO affiliation; and on the ground, judges how much each province city needs to improve. China's each province city data from 2002 to 2006 is used to evaluate technical efficiency by using the input-oriented CCR model and the input-oriented BCC model. Analytical results show that only Shanghai gets continuously the highest efficiency score from 2002 to 2006 and so the other provinces cities need to benchmark Shanghai to elevate their efficiency. There can be regional, cultural and emotional differences among the provinces cities but Tibet, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang get low efficiency scores even after China's WTO affiliation. The Chinese government can make use of efficiency evaluation results by DEA as basic materials in making economic development schemes in order to reduce these deviations as various minority races constitutes China and there are regional deviations of degree of economic development in China.

The purpose of this research is to investigate the factors which effect the intention to reemploy after the retirement and the mediation effect of the social capitalism for retired and prospective retired baby boomers. Starting from 2010, baby boomers have been retiring at a large scale. However retirement at a large scale without securing provision for fiancial wise in later life can lead to many issues regarding social and fiancial wise such as instability of labour market and increase of spending in society welfare cost and such on. Change of individual's self prospective and institutional support to help prepare find new career for next 3decade after the retirement needs to be concretized. The results of this study suggest that the management orientation affects the social capital positively and the autonomous orientation does not affect the relationship between career orientation and social capital. In terms of the relationship between career orientation and reemployment intention, management orientation does not affect the intention of the entrepreneur but affects the reemployment intention positively, while the autonomous intention affects neither entrepreneurial intention nor reemployment intention (+), Respectively. Social capital has a positive effect on the intention of reemployment, and the mediating effect of social capital on the relationship between career orientation and reemployment. Also, while in the work force, potential retiring baby boomer workers should be systematically supported with education, training and reemployment program based on individual's career orientation and allowing them to stay for a longer period in the labour market can be the implication to the solution for the economic stability and increasing social cost such as public pensions.

This article tries to find out some regulatory facts to improve and vitalize roles of social media such as facebook, twitter, etc in the election campaign. For this goal, a theoretical approach is based on the agnostic and open aspects of the regulation system of election. Case study and in-depth interview were used as research methods in this article. The results are as follows. First, some differences are in the election regulatory system regarding the roles of social media in UK, US, Japan and Korea. The election public sphere systems of these countries categorized to the types of legal factors to control political communications in election public sphere; free-speech oriented system(UK. US), limited free-speech oriented system(Korea), normative-oriented system(Japan). Second, most respondents answered they agreed with some improvement ideas to reflect needs of netizen and academic who suggest to minimize regulatory burdens on social media in the political communication during the election campaign.

최근기업의 경쟁력 확보를 위해 기업내의 분산된 이질적인 정보 시스템을 전사적차원에서 통합을 하려는 노력이 활발히 진행되고 있다. 그 중 많은 경우에 통합 문제를 향후의 IT환경을 고려하여 객체지향 개념의 JAVA 및 CORBA를 기반으로 해결하려고 하고 있다. 하지만 실제 기업 환경에서 적용된 경우는 아직 드물다. 본 논문에서는 바이어가 전자회사에 주문한 물품의 생산 현황, 출하까지의 예상시간, 배송일 등을 실시간으로 확인할 수 있는 시스템인 주문 물품 모니터링 시스템(DW- GOMS: DasWoo -Global Ordering status Monitoring System)의 구현에 대해 설명한다. 이 시스템에 대한 사용자의 요구사항 분석은 Use Case를 이용했고 분석 및 설계는 OMT 프로세스를 도입하였고 그 결과는 UML로 표기하는 등 객체지향 개발 방법론을 적용했으며, 설계된 결과를 바탕으로 JAVA 및 CORBA를 기반으로 구현하였다. 구현된 시스템은 CORBA를 적용하여 개발 속도를 현저히 줄일 수 있으며, 시스템 분석/설계에 객체지향 개발 방법론을 적용함으로써 향후 시스템 변경에 유연하게 대응할 수 있게 된다.
