  • So far, the evaluation of machine translation has used a numerical approach, but there is evidence that it is not sufficient to reflect the characteristics or behavior of machine translation users(Hutchins, 2007; Wu et al., 2016; Park et al., 2013). Therefore, this study focused on the purpose of use and purchasing behavior of machine translation users. At this time, the indirect comparison method introduced by Morgan and Hunt(1994) was used to measure cognitive gaps and analyze the purchasing behavior of users. According to the analysis of association rules using cognitive gaps, the smaller the cognitive gap, the more positive the purchase behavior. In addition, procedural knowledge derived from language knowledge is activated in situations involving responsibility, and in routine situations, procedural knowledge trained from pragmatic knowledge works.

  • Given the gaps in the link between leadership, knowledge resource, and innovation capability, this study aims to examine the potential mediating role of knowledge sharing and moderating role of knowledge-centered culture in the relationship between transformational leadership and a firm's capability for innovation. This study applied the Structural Equation Modeling to try out proposal hypotheses in the research model through a questionnaire survey from a sample of 301 participators in 115 small and medium firms in the field of tourism and hotel. The findings disclosed that knowledge-sharing behaviors significantly mediate the transformational leadership-innovation relationship. It highlights the significant impact of explicit knowledge sharing in comparison with the influence of tacit knowledge sharing on innovation capability. The paper also reveals the crucial role of knowledge-centered culture in boosting the knowledge-sharing-innovation relationship. By exploring the mediating role of knowledge sharing and the moderator of knowledge-centered culture, the paper significantly brings insight into different mediating and moderating mechanisms to improve innovation capability. The paper significantly fills up the gaps and provides valuable initiatives on the mechanism of how transformational leadership and specific forms of knowledge-sharing behaviors positively affect innovation capability under the moderating role of knowledge-centered culture.

  • We have been examining the issue of healthcare workers' exposure to antineoplastic drugs for nearly a decade and have observed that there appears to be more publications on the subject matter originating from Europe than from North America. The concern is that findings from Europe may not be generalizable to North America because of differences in handling practices, regulatory requirements, and training. Our objective was to perform a literature review to confirm our observation and, in turn, identify gaps in knowledge that warrants addressing in North America. Using select keywords, we searched for publications in PubMed and Web of Science. All papers were initially classified according to the originating continent and then categorized into one or more subject categories (analytical methods, biological monitoring, occupational exposure, surface contamination, and probability of risk/exposure). Our review identified 16 papers originating from North America and 55 papers from Europe with surface contamination being the subject matter most often studied overall. Based on our results, we are of the opinion that North American researchers need to further conduct dermal and/or urinary drug contamination studies as well as assess the exposure risk faced by healthcare workers who handle antineoplastic drugs. Trends in exposure levels should also be explored.

  • Recently, Linked Open Data has become a large set of knowledge bases. Therefore, the need to query Linked Data using question answering (QA) techniques has attracted the attention of many researchers. A QA system translates natural language questions into structured queries, such as SPARQL queries, to be executed over Linked Data. The two main challenges in such systems are lexical and semantic gaps. A lexical gap refers to the difference between the vocabularies used in an input question and those used in the knowledge base. A semantic gap refers to the difference between expressed information needs and the representation of the knowledge base. In this paper, we present a novel method using an ontology lexicon and dependency parse trees to overcome lexical and semantic gaps. The proposed technique is evaluated on the QALD-5 benchmark and exhibits promising results.

  • Objective: The aim of this paper is to introduce a method that can measure and analyze the judgment gaps between service providers and customers. Background: It is important to understand the good service that service providers and customers are thinking. If there is judgment gap between service providers and customers, it would cause an unsatisfactory service. The judgment gap should be thoroughly investigated for a good service design. Method: Lens model is a human decision making model that was proposed by Brunswick(1952). This study indicates whether the Lens model can be applied to analyze judgment gaps between service providers and customers. As a case study, a library lending service was selected. 5 librarians and 15 customers participated in the experiment that investigates their judgments on a good service. The obtained data were analyzed by a modified lens model. Results: Cue weighting policies of consumers and service providers were similar, except that consumers gave higher weight on tangibility than service providers. Service providers and consumers had a good knowledge on the service quality, but they could not well apply the knowledge to judge it. Conclusion: The lens model may be used to analyze judgment gaps between service providers and consumers in the other service areas. The decision cues that were used in this study can be changed, depending on the characteristics of the target service. Application: The method that is proposed in this study may help to investigate and analyze both consumers' and service providers' judgments on a variety of services.

  • 이 논문은 정보커뮤니케이션 기술을 통하여 정보교류가 활발히 이루어지는 조직내의 지식창출에 있어서 웹블로그 장르분석의 유용성을 밝히는데 그 목적이 있다. 오늘날 지식창출은 지식 중심 업무환경에서 경쟁력 우위를 확보하는데 필수적인 요소이다. 이를 위해 기업들은 지식관리시스템에 막대한 투자를 하고 있다. 그러나 분산지식관리시스템의 하위 정보시스템이 배치된 부서들의 서로 다른 사회문화적 환경으로 인하여 전체 지식관리시스템은 기대했던 성과를 거두지 못하는 경우가 많다. 보다 나은 경쟁력 확보를 위해서는 하위부서간의 사회문화적 차이를 조절하는 것이 중요하다. 웹블로그 사용자들이 사회적 규범을 공유하는 점을 고려한다면 웹블로그가 이러한 사회문화적 차이를 줄이는데 긍정적인 역할을 할 수 있을 것이다. 이 논문은 웹블로그의 장르분석이 조직내의 하위부서들 간의 사회문화적 차이를 줄일 수 있는 중요한 단서를 제공한다고 주장한다. 따라서 이러한 분류 행위가 지식관리시스템의 높은 실패율 문제를 해결하는 하나의 방법이 될 수 있을 것이다. 이 논문은 조직 지식창출이론과 기술의 사회구성론적 관점을 복합적으로 이용하여 사회화가 적용된 분산정보시스템과 그렇지 못한 시스템을 비교하여 보다 나은 지식관리를 구현하는데 유용한 프레임워크를 제공하는데 그 의의가 있다.

  • There are two main artifacts in reconstructed images from in-beam positron emission tomography (PET). Unlike generic PET, in-beam PET uses the annihilation photons that occur during heavy ion therapy. Therefore, the geometry of in-beam PET is not a full ring, but a partial ring that has one or two openings around the rings in order for the hadrons to arrive at the tumor without prevention of detector blocks. This causes truncation in the projection data due to an absence of detector modules in the openings. The other is a ring artifact caused by the gaps between detector modules also found in generic PET. To sum up, in-beam PET has two kinds of gap: openings for hadrons, and gaps between the modules. We acquired three types of simulation results from a PET system: full-ring, C-ring and dual head. In this study, we aim to compensate for the artifacts that come from the two types of gap. In the case of truncation, we propose a method that uses prior knowledge of the location where annihilations occur, and we applied the discrete-cosine transform (DCT) gap-filling method proposed by Tuna et al. for inter-detector gap.

  • Pharmaceuticals in the aquatic environment are trace contaminants of growing importance in environmental health due to their physiologically active nature. Pharmaceuticals could affect non-target species and might eventually damage sustainability of susceptible populations in the ecosystem. Potentials for health consequences among susceptible human population cannot be ruled out since long-term exposure to cocktails of pharmaceuticals, which might be present in drinking water, is possible. Selection of antibiotic resistant microorganisms is of another concern. In order to understand, and if needed, to properly address the environmental health issues of pharmaceutical residues, knowledge gaps need to be filled. Knowledge gaps exist in many important areas such as prioritization of target pharmaceuticals for further risk studies, occurrence patterns in different environments, chronic toxicities, and toxicities of pharmaceutical mixtures. Appropriate treatment technologies for drinking water and wastewater could be developed when they are deemed necessary. One of the simplest, yet most efficient measures that could be undertaken is to implement a return program for unused or expired drugs. In addition, implementation of environmental risk assessment frameworks for pharmaceuticals would make it possible to efficiently manage potential environmental health problems associated with pharmaceutical residues in the environment.
