차세대 웹 환경을 위한 시맨틱 웹에 대한 관심이 날로 증대되고 있다. 이와 더불어 시맨틱 웹에서 자원의 의미적인 관계를 표현하기 위한 언어들에 대한 연구가 활발히 진행중이다. 특히 이러한 연구의 시작점으로 RDF, DAML+OIL 같은 여러 온톨로지 언어들이 등장하였지만 자원의 특성에 대한 기술이나 그들간의 관계에 대한 정의를 명확하게 표현하기에는 미흡한 점이 많다. 그러나 최근에 제안된 OWL은 RDF나 RDF 스키마를 확장하여 보다 의미 있는 자원의 관계를 정의할 수 있다. 본 논문에서는 OWL로 표현된 문서를 저장하기 위한 구조를 관계형 데이터베이스를 기반으로 제안한다. 본 논문에서 제안한 저장 구조는 기존의 RDF와 RDF 스키마를 위한 저장 구조를 확장하여, OWL을 통해 제공되는 클래스나 속성간의 동일성, 또는 이질성, 여러 클래스의 집합 관계 등의 추가적 기능을 지원하는데 목적을 두고 있다. 또한 제안한 저장구조를 이용한 OWL 문서의 질의 형태를 분석하고 이를 기존 RQL을 이용하여 표현하기 위해 OWL의 특성을 반영하도록 RQL을 확장했다.

In this study, we analyzed national mining investment security and country risk, and suggested a new index for exploration and development investment for mining projects in abroad by an analysis of relationship between these grades and mineral resource development investment. For this, potential risks for mining in mineral-rich countries are assessed, and the risk of the exploration and development investment for mining projects is relatively evaluated by OECD country risk. It is noted that countries of the lower ranks in OECD are consistently good agreement with the high grade in Behre Dolbear Group Inc. for favorable mineral exploitation, whereas the higher ranks have shown diverse and high risks for the mining investigation and development. Consequently, it is necessary that assessment of the relationship between mineral resource index and country risk for mining projects to be investigated and developed in future should be applied before business decision of mineral investigation projects in abroad.

A value creation is understood as important business strategy these days in both academics and industry. But this phenomenon is not fully understood based on systematized framework. In this paper, we summarized value research trend based on exploratory research and inductive reasoning by exploring both international and domestic journals. And we built a research framework that can analyze value creation between supplier and customer. Value research prior to 2004 is primarily divided into values of goods or services and relationship values. After 2004, service-dominant (SD) logic has been outlined. There are other research trends to see the relationship value in terms of relationship benefits and relationship in the network or supply chain. 4 critical resource types (financial resource, knowledge resource, efficiency resource, and intellectual resource) and 5 competence types (relational capability, collaboration capability, innovation capability, managing capability) are constructed as principal factors for value creation from inductive reasoning based upon a resource-based view (RBV) and a competence-based view (CBV). The research framework was built based on 4 resources and 4 competences.

Current studies have shown academic and practical interests in effects of various factors on fundraising effectiveness in social service organizations. However, they hardly suggested what factors affect fundraising effectiveness in a clear way. This study intended to suggest a structural relations between factors, such as professional leadership, environmental competitiveness, market orientation, and fundraising effectiveness. The results of the structural equation modelling analysis showed that there were not significant direct effects of professional leadership and environmental competitiveness on fundraising effectiveness, but their indirect effects and mediating effect of market orientation toward donors. Although the study has a limitation to generalize the results for all kinds of nonprofit social service organizations, it has both academic and practical implications to introduce the concept of market orientation for an explanation of fundraising effectiveness, and also to indicate the importance of organizational efforts to keep strong and sound relationships with donors.

The major purpose of this study is to investigate the impact of environmental uncertainties and logistics resources capabilities mediated by relational norms and logistics services on logistics performance in the industrial products. The 272 data were collected from the key informants who were working at the logistics-related departments in the H Heavy Industries & Construction and HSD Engine. The following results were verified using structural equation modeling. First, environmental uncertainties such as dynamism and heterogeneity unexpectedly had insignificant effects on relational norms such as information exchange and flexibility and logistics services such as product availability and on-time delivery. Second, logistics resource capabilities showed unique effects based upon its component's characteristics. For example, Logistics Information Systems did not have direct impact on logistics services but had indirect effect on logistics services via relational norms. On the other hand, logistics resources such as logistics specific assets and transportation service competencies had direct impact on logistics services but not on relational norms. Third, relational norms between transaction partners significantly affected logistics services but had insignificant effects on logistics performance such as logistics costs reduction and delivery qualities. Fourth, consistent with several studies, excellent logistics services between industrial purchaser and suppliers based upon relational norms did have significant effect on logistics performance such as delivery consistency and delivery qualities. Finally, the empirical results in this study could be strategic logistics management guidelines based upon the theoretical relationships among the environmental uncertainties, logistics information systems, logistics resources, relational norms, logistics services, and logistics performance.

주요 현물유가(WTI, Brent, Oman, Dubai)와 선물유가간의 동태적 관계를 시계열 분석 방법을 이용하여 살펴보았다. 현물유가 및 선물유가들은 1차 적분된 시계열(I(1))로 보여진다. 현물유가들사이 및 현물유가와 선물유가사이에도 공적분관계(cointegration relation)가 있는 것으로 보여진다. 한편, 선물유가는 현물 유가를 인과(Granger-cause)하지만, 현물유가는 선물유가를 인과하지 않는 것으로 나타났다. 이러한 공적분관계 및 인과관계의 결과는 합리적 기대가설(rational expectations hypothesis)에 의한 효율적 석유시장(efficient oil markets)과 일치하는 것으로 보여진다. 수정오차모형(error correction model)에 의해 3/4분기 및 4/4분기의 유가들을 예측해 보았다.

Grit is a person's passion and perseverance that drive them to achieve long-term and meaningful goals. The purpose of this study was to identify practical resources that can affect single parents' grit. Using the fourth-year panel data from the Korean Children and Youth Panel Survey 2018 (KCYPS 2018), descriptive statistics were produced and a correlation analysis was conducted for 284 single parents. Hierarchical regression analysis was also performed to explore the demographic factors, personal resources(psychological, lifestyle/health), and family resources(family relationships/child, economic) that affect single parents' grit. First, the correlation analysis revealed that single parents' grit had a significant correlation with age, education status, life satisfaction, happiness, self-esteem, smartphone dependency, physical activity time, frequency of breakfast consumption, household size, parent's satisfaction with child's school achievement and school adjustment, subjective family economic status, and private education expenses. Second, the hierarchical regression analysis revealed that education status, self-esteem, employment status, smartphone dependency, physical activity time, household size, parent's satisfaction with child's school achievement, and subjective family economic status were significant factors affecting single parents' grit. Based on the research results, this study suggests directions for programs and policies to provide a stable environment for single-parent families to raise their children.

For semantic retrieval in semantic web environment, it is an important factor to manage and manipulate distributed resources. Ontology is essential for efficient search in distributed resources, but it is almost impossible to construct an unified ontology for all distributed resources in the web. In this paper, we assumed that most information in the web environment exist in the form of RDBMS, and propose a matching method between domain ontology and the existing RDBMS tables for semantic retrieval. Most previous studies about matching between RDBMS tables and domain ontology have extracted a local ontology from RDBMS tables at first, and conducted the matching between the local ontology and domain ontology. However in the processing of extracting a local ontology, some problems such as losing domain information can be occurred since its correlation with domain ontology has not been considered at all. In this paper, we propose a methods to prevent the loss of domain information through the similarity measure between instances of RDBMS tables and instances of ontology. And using the relational information between RDBMS tables and the relational information between classes in domain ontology, more efficient instance-based matching becomes possible.
