  • 본 총설에서는 산림생태계의 생태수문시스템을 복잡계의 관점에서 바라 보았을 때, (1) 생태수문계의 구성 요소들이 상호작용을 통해 망을 형성하고 집단적인 반응을 하며, (2) 복잡정교한 정보 처리를 수행하고, (3) 자기-조직화 과정을 통해 적응해 가는 복잡계의 특징들을 볼 수 있을 것이라고 가정하였다. 제시된 과정망 그리기의 결과는 생태수문계에 관여하는 다양한 시공간 규모의 과정들이 실제로 관련 변수들 간의 되먹임과 정보 흐름의 망을 형성하고 있음을 명확히 보여준다. 또한 구성 변수들이 독특한 형태(즉, 차별화된 결합 형태, 방향성 및 시간 지연 규모)로 정보를 교환함으로써, 망 안에 또 다른 망을 형성하며 일관되게 조직화되어 특정한 하부계들을 구성하는 계층적(hierarchical) 구조를 잘 나타낸다. 이러한 하부계들이 종관 하부계(SS), 대기경계층 하부계(ABLS), 생물리 하부계(BPS), 생물리화학 하부계(BPCS) 등으로 다양하게 나타남을 보여준다. 주목할 점은, 이러한 하부계들이 서로 되먹임 고리들을 맺거나 끊음으로써 지역하부계(RS)와 같은 새로운 하부계의 집합체를 생성하거나, 또는 분리시킨다는 것이다. 이러한 과정은 바로 복잡계의 특성인 자기-조직화 과정의 증거로서, 생태계가 계층적으로 조직화되어 성장하고 발전하면서, 자연적/인위적 교란 속에서도 자기-조직화를 통해 동적 평형을 유지하며, 환경 변화에 적응하고 진화해 나감을 함축적으로 의미한다. 생태계의 건전성은 시스템의 자기-조직화 과정들이 유지될 때에 비로소 보존되는 것이기 때문에, 이러한 관점에서 과정망 연구방법은 의미있고 이치에 닿는다.

  • 본 연구는 노인생활시설 사회복지사들의 직무 및 조직특성과 직무만족도의 관계에 있어서 전문직업적 정체성의 매개효과를 보고자 하였다. 연구를 위해 대구시 전체 노인생활시설 24개소에 근무하는 사회복지사 180명을 대상으로 자료를 수집하였다. 매개효과 검증을 위한 통계적 분석은 위계적 회귀분석 (Window SPSS 12.0)을 이용하였다. 연구 결과, 직무 및 조직특성, 전문직업적 정체성, 직무만족에 대한 대상자들의 인식은 직무만족(3.28±.63)이 가장 높았으며 전문직업적 정체성(3.23±.50), 직무특성(3.17±.49), 조직특성(3.17±.58)의 순으로 나타났다. 그리고 직무특성(β=.699, p<.001)과 조직특성(β=.871, p<.001)은 직무만족에 유의적인 영향을 미치는 변수로 확인되었다. 뿐만 아니라 전문직업적 정체성을 매개변수로 사용한 경우 직무만족에 대한 직무특성(β=.543, p<.001)과 조직특성(β=.773, p<.001)의 영향력이 감소되어 전문직업적 정체성의 부분적 매개효과를 확인할 수 있었다.

  • A multitude of protein-coding sequence variations (CVs) in the human genome have been revealed as a result of major initiatives, including the Human Variome Project, the 1000 Genomes Project, and the International Cancer Genome Consortium. This naturally has led to debate over how to accurately assess the functional consequences of CVs, because predicting the functional effects of CVs and their relevance to disease phenotypes is becoming increasingly important. This article surveys and compares variation databases and in silico prediction programs that assess the effects of CVs on protein function. We also introduce a combinatorial approach that uses machine learning algorithms to improve prediction performance.

  • Although the concept of viewing knowledge as a critical resource has been widely accepted in prior studies, it is not fully understood how to acquire available knowledge in order to improve organizational effectiveness. However, it si sure that organizational knowledge management should pursuit the achievement of the business goal by delivering relevant and useful information to the right person at the right time. Group Support System (GSS) can play an important role to transfer scatter information into meaningful business knowledge for supporting strategic corporate decision-making. This study proposes a fuzzy GSS framework for acquiring workgroup knowledge from individual memory and aggregating workgroup knowledge to organizational knowledge. This study also proposes an architecture to support the fuzzy GSS framework. The architecture consists of user agents, information management agents, and a fuzzy model manager. To illustrate how the fuzzy GSS framework can be used to support the whole process of organization knowledge acquisition, an Internet-based GSS was developed and applied in a marketing decision process. It showed that the framework was effective for acquiring organizational knowledge.

  • Rural enterprise clusters in India have often been characterized by low-end products, poor income earning options and a near-absence of innovativeness. This has implied limited market access, inadequate organization of production and distancing from sources of formal knowledge. Policy neglect of rural industrialization notwithstanding this paper explores the nature of institutional constraints to innovation through intensive case studies of five rural artisan clusters (handlooms and handicrafts) in as many Indian states. Whether it relates to access to loan finance or technology support or linking to markets, the formal institutions (public or private) have been distanced by informality that typifies most rural enterprise clusters. An obsession with a sectoral approach to cluster development has negated addressing infirmities of the space of enterprise, even as scope for learning from some Asian economies in rural enterprise promotion exists. The paper also enquires if the innovation systems have been inclusive and pro-poor.

  • SCM system is required inter-industrial cooperation as well as inter-organizational cooperation. It means not only standardization of inter-organization but also standardization of inter-industry. SCM makes possible one circulation from fiber to retail industry in the respects of information and product flows. QR is the SCM of textile apparel industry, which satisfy customer need with least cost and maximum profit. Customer-oriented supply chain system focused on information sharing, cost reduction, inventory control, lead time reduction, quick response on customer demand. How we can measure the performance of successful SCM is issued on the approach of Balanced Scorecard which evaluates 4 perspectives such as customer perspective, internal business perspective, financial perspective, and innovation and learning perspective. This can project the blueprint of textile fashion business to right direction with vision.

  • With the success of the genome-wide association studies (GWASs), many candidate loci for complex human diseases have been reported in the GWAS catalog. Recently, many disease prediction models based on penalized regression or statistical learning methods were proposed using candidate causal variants from significant single-nucleotide polymorphisms of GWASs. However, there have been only a few systematic studies comparing existing methods. In this study, we first constructed risk prediction models, such as stepwise linear regression (SLR), least absolute shrinkage and selection operator (LASSO), and Elastic-Net (EN), using a GWAS chip and GWAS catalog. We then compared the prediction accuracy by calculating the mean square error (MSE) value on data from the Korea Association Resource (KARE) with body mass index. Our results show that SLR provides a smaller MSE value than the other methods, while the numbers of selected variables in each model were similar.

  • In previous nuclear genomic association studies, Random Forests (RF), one of several up-to-date machine learning methods, has been used successfully to generate evidence of association of genetic polymorphisms with diseases or other phenotypes. Compared with traditional statistical analytic methods, such as chi-square tests or logistic regression models, the RF method has advantages in handling large numbers of predictor variables and examining gene-gene interactions without a specific model. Here, we applied the RF method to find the association between mitochondrial single nucleotide polymorphisms (mtSNPs) and diabetes risk. The results from a chi-square test validated the usage of RF for association studies using mtDNA. Indexes of important variables such as the Gini index and mean decrease in accuracy index performed well compared with chi-square tests in favor of finding mtSNPs associated with a real disease example, type 2 diabetes.
