This paper covers the development process of multimedia evaluation system, especially focused on customer satisfactory factors while customers navigating net-based Interactive multimedia system. Customers usually experience new level of interaction cased by newly developed web-based technology In ordinary multimedia system. However, if it gives customers satisfactory experience is a matter of question. To find out the relationship between customer satisfaction and interactivity factors exposed by multimedia system, a model has been developed which describes the structure of web-based multimedia system and its relation to customer satisfactory factors. Five different experiments, including 'semantic differential', 'focus group interview', and 'expert review', has been conducted and four customer satisfactory factors were identified. Those are 'customery value', 'structural perfectness', 'visual perfectness', and 'contemporaneity'. With these factors and newly delveoped evaluation system, 7 different web-site has been evaluated and analyzed at the end of this report.

형태소를 공유하고 있는 어휘가 심성 어휘집(mental lexicon)에 어떻게 저장되어 있고 어떻게 어휘 접근되는지에 관하여 여러 설명이 제기되었다 첫 번째 가설은 형태소 공유 어휘는 심성 어휘집에 모두 같은 어근 혹은 어간을 중심으로 저장되어 있다는 것이다. 두 번째 가설은 어간이나 어근으로의 분석을 통해 활용된 단어를 이해하는 것이 아니라 일단 활용된 형태의 어휘를 심성 어휘집에서 찾고, 만일 해당되는 것이 발견되면, 그 활용된 어절의 이해가 끝나게 되고, 만일에 해당되는 것이 심성 어휘집에 존재하지 않는 경우에만 부수적인 과정으로 구성 형태소로의 분석이 이루어진다는 것이다. 세 번째 가설은 어휘의 품사, 어휘의 빈도, 형태소 활용의 규칙성 등에 따라 구성 형태소로의 분석을 통해 활용된 단어를 이해하거나 아니면 활용된 어휘의 직접적인 접근을 통해 활용된 단어를 이해한다는 것이다. 본 연구에서는 이 세 종류의 가설 중에 어느 가설이 옳은 것인지를 조사하기 위해, "먹은" 흑은 "쥐어"와 같은 한국어 어절을 이용하여 형태소 표상 양식과 이해 과정을 다루었다. 본 연구의 목적을 위해 점화 어휘 판단 과제(primed-lexical decision task)를 사용하였다. 실험 1은 "먹은"처럼 동사 "먹다"로도 해석이 가능하고 명사 "먹"으로도 가능한 중의적 어절을 점화 문자열로 제시하고 이 문자열이 두 의미와 관련된 목표 단어 재인에 어떤 영향을 끼치는지를 조사하였다. 만일에 "먹"이라는 어근 혹은 어간으로의 분석을 통해 이 어절을 이해한다면 두 종류의 의미와 관련된 조건 모두에서 촉진적 점화 효과(facilitatory priming effect)가 나타날 것이고, 어절 전체로의 어휘 접근 과정이 일어난다면 사용빈도에서 높은 동사 뜻과 관련된 조건에서만 촉진적 점화 효과가 나타날 것이다. 실험 1의 결과는 두 종류의 의미가 모두 활성화되는 것을 보여 주었다. 즉, "먹은"과 간은 어절 이해는 구성 형태소로의 분석과 구성 형태소 어휘 접근을 통해 어절 이해가 이루어진다는 가설을 지지하고 있다. 실험 2에서는 실험 1과 다르게 한 뜻으로만 안일 수밖에 없는 "쥐어"와 같은 어절을 사용하여 이런 경우에도(즉, 어절의 문맥이 특정 뜻으로 한정하는 경우) 구성 형태소로의 분석 과정이 일어나는지를 조사하였다. 실험 2의 결과는 실험 1의 결과와는 다르게 어간의 한가지 의미와 관련된 조건만 촉진적 점화 효과가 나타나는 것을 보여주었다. 특히, 실험 2에서 SOA가 1000msec일 경우, 두 의미의 활성화가 나타나는 것을 보여주었는데, 이 같은 결과는 어절 문맥이 특정한 의미로 한정시킬 경우는 심성어휘집에 활용형태로 들어있다는 것이다. 또한 명칭성 실어증 환자의 경우에는 즉시적 점화과제에서는 일반인과 같은 형태소 처리과정을 보였으나, 그이후의 처리과정이 일반인과 다른 형태를 보였다. 실험 1과 실험 2의 결과는 한국어 어절 분석이 구문분석 또는 활용형태를 통해 어휘 접근되는 가설을 지지하고 있다. 또 명칭성 실어증 환자의 경우에는 지연된 점화과제에서 형태소 처리가 일반인과 다르다는 것이 밝혀졌다. 이 결과가 옳다면 한국의 심성 어휘집은 어절 문맥에 따라서 어간이나 어근 또는 활용형 그 자체로 이루어져 있을 것이다.

The development of collaboration among information systems in accordance with changes in enterprises' business environment brings about the problems of duplication of the existing business services and increase in costs of maintenance. Accordingly, Web service has been suggested as the standard of distributed computing to prevent the duplication of services within the same business domain and to attain the services that are already being utilized. But since the data needed for Web services are not standardized, it is difficult for the users to find services that meet diverse business purposes. In this paper, we construct an ontology-based collaboration system for service interoperability. The ontology can support fusion service by finding services which are existed interdependently under the distributed environment for collaboration processing. The role of the collaborative system includes development, registration and call of services based on ontology. A local systems request collaboration support through the service profile. Collaborative system supports the development of service using the service profiles, represents the semantic association between real data through system ontology, and infers relationship between instances contained in the services. Based on this, we applied the travel booking services for collaboration system. As a result, service can be managed effectively preventing collision in collaborative system, and we verify that the mapping between system is reduced.

RDF is the base ontology model which is used in Semantic Web defined by W3C. OWL expands the RDF base model by providing various vocabularies for defining much more ontology relationships. Recently Jain and Farkas have suggested an RDF access control model based on RDF triple. Their research point is to introduce an authorization conflict problem by RDF inference which must be considered in RDF ontology data. Due to the problem, we cannot adopt XML access control model for RDF, although RDF is represented by XML. However, Jain and Farkas did not define the authorization propagation over the RDF upper/lower ontology concepts when an RDF authorization is specified. The reason why the authorization specification should be defined clearly is that finally, the authorizatin conflict is the problem between the authorization propagation in specifying an authorization and the authorization propagation in inferencing authorizations. In this article, first we define an RDF access authorization specification based on RDF triple in detail. Next, based on the definition, we analyze the authoriztion conflict problem by RDF inference in detail. Next, we briefly introduce a method which can quickly find an authorization conflict by using graph labeling techniques. This method is especially related with the subsumption relationship based inference. Finally, we present a comparison analysis with Jain and Farkas' study, and some experimental results showing the efficiency of the suggested conflict detection method.

This study was conducted to explore the experience and its meaning of the elderly residents in long-term care facilities(LTCFs). It is aimed to find the role of family and society for the qualitative care of elderly living in LTCF and to seek social welfare measures. For this purpose, qualitative research data was collected by conducting in-depth interviews and participation observations on 8 elderly residents at 4 LTCFs in Seoul, Incheon, and Gyeonggi Province. The collected data were analyzed using Giorgi's phenomenological research method. The analysis results show that 33 semantic units, 14 subcomponents, and 4 upper components. The 4 upper components showed up as 「Crumbling my existence」, 「The life thrown into an unfamiliar environment」, 「New relationship where discomfort and gratitude coexist」 and 「My life I want to find」. Among them, 「My life I want to find」 was the essence of the living experiences of elderly residents in LTCF. Through this study, it was suggested creating an environment to provide facilities access preparation program for the elderly, developing and activating various family participation programs, providing conditions of Aging in place for the elderly, and developing and activating community resource linkage programs.

In this article, the narrative strategy of Ryusuke Hamaguchi's is researched focusing on multi-layered intertextuality. is framed in the form of a 'story in a story that embraces a story', and the recognition of intertextuality has an important meaning in examining the storytelling strategy of . Because this movie was adapted from the short stories from Haruki's , the various stories included in the film overlap to form the overall narrative. Therefore, in order to understand properly, it is important to understand the organic semantic relationship between the texts in the movie. Understanding the narrative of is also the process of interconnecting textual content of multiple texts included in the film. In , the dream story told by Otto, Gafuku's wife, the main character, and in the play are elaborately linked to the narrative of the entire film in layers and three dimensions with text in a frame. Hamaguchi reinforces the need for the audience through the intertextual narrative strategy of . In addition, the metaphor and personalized space of contributes to the effective delivering the narrative of healing to the audience.

How does authenticity influence the process that conducts a company's CSR Strategy? Authenticity, an internal/external alignment condition that an employee feels in relation to an organization, means the decision on how true and beneficial to employees through their experiences, such as thoughts and emotions. Also, it can be understood as a process of meaning formation between the organization's strategy to conduct CSR and the perception of employees conducting CSR. To prove the relation between authenticity and CSR clearly, we used various techniques like Text Mining, Topic Modeling and Semantic network analysis about O corporation's 657 review data, from 2015 to 2021. As a result of the analysis, we find out the special issues and types. The analysis shows that the issue concerning the 'external image' is the biggest characteristic of authenticity perception in other conditions. Furthermore, the types of authenticity perception evaluations are largely divided into acceptance and rejection, in detail, five categories. This study indicates that organizations should consider both external and internal conditions when establishing CSR strategies. In addition, it is necessary to be an interactive circular relationship between the organization and employee, collecting and reflecting employee's perceptions. Finally, this study proposes ways to overcome problems related to interaction.

Although humans exist as Homo Empathicus, human society is actually constantly divided and conflicted between groups. The human empathy response is very sensitive to the justice of others, and depending on the level of others' justice, they may feel empathy or schadenfreude to the suffering of them. However, our empathy to others' suffering are not always fair, and have inherent limitations of ingroup-biased empathy. Depending on whether the suffering other persons belongs to an ingroup or an outgroup, we may feel biased empathy or biased schadenfreude to them without even realizing it. Recent advances in information and communication technology facilitate biased access to ingroup-related SNS or ingroup media, thereby deepening the establishment of a more biased semantic information network related groups. These processes, through interacting with the inherent limitation of empathy, can form a vicious cycle of more biased ingroup empathy and ingroup-related activities, and accelerate divisions and conflicts. This research investigated the properties and limitations of empathy by reviewing studies on the neural mechanism of empathy. By examining the relationship between empathy and justice from a neuroscientific point of view, this research tried to illuminate the modern society of division and conflict in a different dimension from the classical perspective of social science.

This research aims to identify startup trends by analyzing a large number of news articles through semantic network analysis. Using the BIGKinds article analysis service provided by the Korea Press Foundation, 330,628 news articles from 19 newspapers from January 2013 to December 2022 were comprehensively analyzed. The study focused on exploring the changes in key issues over the past decade, considering the impact of the social environment and global economic trends on entrepreneurship. We compared the number of news articles and changes in issues before and after the COVID-19 pandemic, and visualized entrepreneurship trends through frequency analysis, relationship analysis, and correlation analysis. The results of the study showed that the top keywords for entrepreneurship-related words are startup activation and commercialization, and the correlation between COVID-19 and entrepreneurship keywords is almost negligible in a linear sense, but the number of news articles decreased during the pandemic, which has an impact. In particular, the most frequently mentioned keywords are Ministry of SMEs and Startups, place is the United States, and person is limited. The agency was the SBA, and the entrepreneurship sector is more affected by social issues than any other sector, with the important characteristics of increased frequency of prompt access. This study supplies essential basic data for understanding and exploring issues and events related to entrepreneurship and suggests future research topics in the field.

The concept of "green infrastructure" emphasizes the close relationship between natural and urban social systems, thereby providing services that protect the ecological environment and improve the quality of human life. The Green View Index(GVI) is an important indicator for measuring the supply of urban green space and contains more 3D spatial elements concerning the green space ratio. This study focused on an area within the Third Ring Road in the city of Chengdu, Sichuan Province, China. The purposes of this study were three-fold. First, this study analyzed the spatial distribution characteristics of the GVI in urban streets and its correlation with the urban park green space system using Street View image data. Second to analyze the characteristics of low GVI streets were analyzed. Third, to analyze the connectivity between road traffic and street GVI using space syntax were analyzed. This study found that the Street GVI was higher in the southwestern part of the study area than in the northeastern part. The spatial distribution of the street GVI correlated with urban park green space. Second, the street areas with low GVI are mainly concentrated in areas with dense commercial facilities, areas with new construction, areas around elevated roads, roads below Class 4, and crossroads areas. Third, the high integration and low GVI areas were mainly concentrated within the First Ring Road in the city as judged by the concentration of vehicles and population. This study provides base material for future programs to improve the GVI of streets in Chengdu, Sichuan Province.
