The phenotypic response of a cell results from a well orchestrated web of complex interactions which propagate from the genetic architecture through the metabolic flux network. To rationally design cell factories which carry out specific functional objectives by controlling this hierarchical system is a challenge. Transcriptome analysis, the most mature high-throughput measurement technology, has been readily applied In strain improvement programs in an attempt to Identify genes involved in expressing a given phenotype. Unfortunately, while differentially expressed genes may provide targets for metabolic engineering, phenotypic responses are often not directly linked to transcriptional patterns, This limits the application of genome-wide transcriptional analysis for the design of cell factories. However, improved tools for integrating transcriptional data with other high-throughput measurements and known biological interactions are emerging. These tools hold significant promise for providing the framework to comprehensively dissect the regulatory mechanisms that identify the cellular control mechanisms and lead to more effective strategies to rewire the cellular control elements for metabolic engineering.

Recently, an ERP (Enterprise resource Planning) system has been becoming an essential S/W tool for companies to manage their business processes and manufacturing resources. As the information exchange becomes more complex, not only corporate companies but also small- and mid- sized enterprises (SMEs) are required to build an ERP system. However, for small- and middle- sized companies, the adoption of ERP systems becomes challenging due to high cost and long installation time of the system. This paper presents a novel concept of an adaptive ERP system incorporating the ontology structure of the business supply chain information. The proposed ERP installation methodology is illustrated with an example of a door-trim manufacturing company in the automotive supply chain.

RDF(Resource Description Framework)는 시맨틱 웹에서 메타 정보를 기술하는 온톨로지 언어로 많이 사용되고 있다. 온톨로지는 실세계에 대한 모델링을 기반으로 하기 때문에 끊임없이 갱신이 발생한다. 이런 갱신을 찾고 분석하는 일은 지식 관리 시스템에서 핵심이 된다. 기존의 RDF 모델에 대한 변경 탐지 기법들은 구조적 변경에 초점을 두었으나 RDFS 함의 규칙을 적용하여 좀 더 작은 크기의 변경 부분을 찾는 연구들이 소개되고 있다. 하지만 RDF 모델의 추론은 데이타 크기와 시간의 증가에 영향을 미친다. 본 논문에서는 RDFS 함의 규칙을 효율적으로 사용하는 변경 탐지 기법을 제안한다. 제안된 기법은 후방향 전진 추론 기반으로 모델 일부분에만 추론을 적용하여 변경 내용을 계산한다. 실제 사용하는 RDF 데이타들을 사용하여 기존의 변경 탐지 기법과의 비교 실험을 통해 성능을 향상시킬 수 있음을 보인다.

This study explored the conceptual framework of dieticians' intentions to recommend functional food and the mediating role of consumption frequency. A web-based survey was designed using a self-administered questionnaire. A sample of Korean dieticians (N=233) responded to the questionnaire that included response efficacy, risk perception, consumption frequency, and recommendation intention for functional foods. A structural equation model was constructed to analyze the data. We found that response efficacy was positively related to frequency of consumption of functional foods and to recommendation intention. Consumption frequency also positively influenced recommendation intention. Risk perception had no direct influence on recommendation intention; however, the relationship was mediated completely by consumption frequency. Dieticians' consumption frequency and response efficacy were the crucial factors in recommending functional foods. Dieticians may perceive risks arising from the use of functional foods in general, but the perceived risks do not affect ratings describing dieticians' intentions to recommend them. The results also indicated that when dieticians more frequently consume functional foods, the expression of an intention to recommend functional foods may be controlled by the salience of past behaviors rather than by attitudes.
