다국어 입력기에서 한글 입력의 최적화를 위하여 문자별 보편성과 개별성을 밝혀내어서 어떤 문자의 개별성이 다른 문자의 보편성을 헤치지 않도록 충돌 요인을 최대한 낮추어야 한다. 특히 한글은 표음 문자로서 음절 및 음소문자의 특성을 가지고 있고, 한글전용을 하고 있다. 반면에 일본어와 중국어는 음절문자에 해당하며 가나 또는 병음을 입력하여 마지막에는 한자로 바꾸어야 한다. 여기서 훈민정음창제원리를 기본으로 삼아 최적화에 적용하고자 한다.

개별 대수층에 냉수와 온수를 저장하여 수자원과 냉난방 열원으로 활용하는 방안에 대한 평가를 지열-지하수 부정류 모델링을 통해 수행하였다. 저장 및 회수 가동 시간이 증가함에 따라서 각각의 대수층 내에 온열과 냉열이 축열되는 현상이 확인되었으며, 지하수 유동에 의해 축열된 수체가 지하수 흐름방향으로 이동하는 현상을 확인 하여 지하수 유동이 축열 정도를 결정하는 요인이 될 수 있음을 확인하였다. 설정된 모델에 대하여, 두 개의 개별 대수층 사이의 열 간섭은 거의 없는 것으로 나타났다. 주입과 양수의 가동 횟수가 증가되면, 대수층 축열 효과는 증대되는 것으로 나타났다. 열-지하수 모델링을 통한 온도 예측은 실제 냉난방의 효율성을 결정짓는 수온을 정량적으로 계산할 수 있는 유용한 기술로 평가됨과 더불어, 수자원의 지하 저장을 통해 효율적으로 물을 확보하고 관리할 수 있는 방안이 될 수 있을 것으로 기대된다.

This paper aims to derive success factors that successfully lead an artificial intelligence (AI) project and prioritize importance. To this end, we first reviewed prior related studies to select success factors and finally derived 17 factors through expert interviews. Then, we developed a hierarchical model based on the TOE framework. With a hierarchical model, a survey was conducted on experts from AI-using companies and experts from supplier companies that support AI advice and technologies, platforms, and applications and analyzed using AHP methods. As a result of the analysis, organizational and technical factors are more important than environmental factors, but organizational factors are a little more critical. Among the organizational factors, strategic/clear business needs, AI implementation/utilization capabilities, and collaboration/communication between departments were the most important. Among the technical factors, sufficient amount and quality of data for AI learning were derived as the most important factors, followed by IT infrastructure/compatibility. Regarding environmental factors, customer preparation and support for the direct use of AI were essential. Looking at the importance of each 17 individual factors, data availability and quality (0.2245) were the most important, followed by strategy/clear business needs (0.1076) and customer readiness/support (0.0763). These results can guide successful implementation and development for companies considering or implementing AI adoption, service providers supporting AI adoption, and government policymakers seeking to foster the AI industry. In addition, they are expected to contribute to researchers who aim to study AI success models.

This paper is concerned with analyzing the images of Korean automobiles using, so called, sensory engineering, which adapts the sensory and subjective assessment of human beings in evaluating the quality of product. The methodology of analysis is suggested in this paper according to the following steps. First, 14 pairs of adjectives, which describe the image of object cars in view of the semantic differential method, are derived from consulting with several expert panels. Nextly, factor analysis is performed in order to obtain the axises, by which the images space of the object automobiles are specified, and then the images of the object automobiles are measured by the coordinate of all the object automobiles in the image space. In this paper, a sensory estimation experiment is performed to a panel consisting with In undergraduate students residing in the region of Daegu. From the result of analysis of this paper, target images, which the automobile manufacturers are intended, are achieved by and large except one company.

Chinese consumers get more interests in the brands which show the consumers with th trust rather than the those which provide consumers with excessive information on brand. Accordingly, this study aimed to find out that the antecedents of brand authenticity such as brand consistency, continuity, individuality, authority, ethics affect the brand aura through brand authenticity and surveyed data from a total 400 Chinese consumers for the analysis. As a result, this article is summarized as followings. First, brand continuity, individuality, authority affected brand authenticity but brand consistency and ethics did not have a direct effect on brand authenticity. Second, brand authenticity had positive effect on brand aura. This study provides information on the antecedents of brand authenticity of Chinese consumers. Further, it will provide meaning suggestion point of the importance of brand authenticity in establishing of brand aura.

1990년대 중반을 넘어서면서 성장둔화에 직면한 한국경제의 애로요인으로 인건비, 토지가격, 금리 등 생산요소 가격의 상승, 기술개발의 부족 및 물류애로에 따른 과다한 물류비의 부담 등이 지적되고 있다. 이 세 가지 요인 중에서 생산요소가격의 문제는 거시경제정책의 변수의 성향을 가지고 있으며, 기술개발에 대한 투자와 결실은 단기(Short-Run)에 해결되기는 곤란하므로 개별기업은 물론 정부를 포함하는 제 경제주체의 노력에 따라서 물류비용을 획기적으로 절감하고 그를 통해 국가경쟁력의 회복 또는 강화의 계기를 발견하고자 하는 노력이 다각적으로 펼쳐지고 있다.

The main objective of the research is to analyse the efficiency of bus route operation system which is comprised of Individual Operation System and Joint Operation System. While the reformation of bus route operation system has been usually considered as a service upgrade strategy for inner-city bus operation, it is comparatively difficult to have background information for policy establishment due to shortage of analytical research output. This study adopts Data Envelopment Analysis technique to estimate efficiency of 101 bus routes in Ulsan Metropolitan City which operates two types of operation systems at the same time as of 2009. The analysis results tells that the reason of inefficiency lies on pure technical factor for J.O.G., and scale factor for I.O.G.. It is also confirmed that there is bus route which inefficiently operated in I.O.G and city government needs to prepare the specific plan to upgrade pure technique efficiency before reformation of bus route operation system for successful installation.

The purpose of this study is to subdivide responsive teaching types proposed in the previous study in order to observe the change in the responsive teaching types in teacher educational programs, and to identify factors that impede changes in responsive teaching types. To this end, an educational program including introduction of responsive teaching, case analysis of responsive teaching, individual assignments and group discussions on facilitator type educational scenarios is provided for chemistry teachers who participated in a chemistry education course established in a graduate school of education. Based on previous research, when the teacher's teaching method was analyzed as evaluator, transfer, guide and facilitatore, a type that could not be classified was observed. In this study, responsive teaching types were added by adding two types: explorer and interpreter. In addition, through individual assignments and group discussion data, we could observe the factors that hinder teachers' responsive teaching changes. The obstacles that impede the change to responsive teaching were classified into teacher factors, student factors, and environmental factors. Among the obstacles, teacher factors include a belief in teacher-led instruction, a belief in the role of a teacher as a transfer of knowledge, a belief that the curriculum should be followed, a lack of understanding of the teacher about students, and a lack of the teacher's ability to lead student-led expansion. The student factor was distrust of the student's competence. Also, as an environmental factor, there was an educational environment such as multi-students class. Effective teacher education on responsive teaching can be achieved only when the perception related to these obstacles can be removed.

This study was aimed at identifying the influence of Creative Thinking Filtering Mode program in international gifted program: how much it influences to improve the cognitive domains of creativity (fluency, flexibility, originality) and affective domains of creativity (independence, curiosity, diversity, sensitivity, sense of humor, individuality. To analyze data, ANCOVA(Analysis of Covariance)test was conducted, and the results are as belows. Firstly, the group applied in CTFM program was higher than controlled group on the domains of cognitive and affective. Specifically, in the factors of fluency, flexibility and originality among three cognitive domains and factors of individuality.In affective domains of creativity, independence, curiosity, diversity, a sense of humor among the five factors except of sensitivity were higher. Secondly, the result of analyzing the difference between before and after applying CTFM program was that three elements in cognitive domains : fluency, flexibility and originality improved, especially, the fluency was the most improved. Thirdly, the result of analyzing the difference of affective factor between before and after applying CTFM program was that the originality, diversity, a sense of humor and individuality among the 6 elements of affective domain improved, especially the individuality was the most improved.
