스마트 스피커는 인공지능을 활용하여 음악, 일정, 날씨, 상품 등 다양한 정보와 콘텐츠들을 검색, 이용할 수 있는 대화형 음성 기반 서비스를 제공하는 기기이다. 인공지능 기술은 데이터가 축적될수록 이를 활용하여 더욱 정교하고 최적화된 서비스를 이용자에게 제공한다. 따라서 스마트 스피커 제조사들은 초기에 공격적인 마케팅을 통해 플랫폼 구축에 힘썼다. 하지만 스마트 스피커의 사용빈도는 월 1회 미만이 전체의 3분의 1 이상을 차지하고, 사용자 만족도도 49%에 그치는 것으로 나타났다. 이에 지속적인 이용활성화와 만족도 증진을 위해 스마트 스피커의 사용자 경험을 강화할 필요성이 대두되었다. 이에 본 연구에서는 스마트 스피커의 사용자 경험을 분석하고, 이를 바탕으로 스마트 스피커의 사용자 경험 강화 방안을 제시하고자 한다. 본 연구는 사용자가 직접 작성한 실제 리뷰 데이터를 수집하여 스마트 스피커 사용자 경험 차원을 기반으로 분석 결과를 해석했다는 점에서 의의가 있다. 또한 스마트 스피커 사용자 경험 차원을 개발하여 텍스트 마이닝 결과를 해석한 것에서 학술적 의의가 있다. 본 연구 결과를 통해 스마트 스피커 제조사에게 실무적으로 사용자 경험 강화를 위한 전략을 제안할 수 있다.

A dramatic development in the new technology of copying materials has presented us with massive problems on reconciling the conflicts between copyright owners and potential users of copyrighted materials. The adaptation to this changing condition led some countries to revise their copyright laws such as in the U. S. in 1976 and in Korea in 1984 for merging with the international or universal copyright conventions in the future. Copyright defined as exclusive rights given to copyright owners aims to secure a fair return for an author's creative labor and to stimulate artistic creativity for the general public good. The exclusive rights on copyrightable matters, generally for reproduction, preparation of derivative works, public distribution, public performance, and public display, are limited by fair use for scholarship and criticism and by library reproduction for its preservation and interlibrary loan. These limitations on the exclusive rights are concerned with all aspects of library services and cause a great burden on librarian's daily duty to provide balance between the rights of creators and the needs of library patrons. The fair use as one of the limitations on it has been coupled with enormous growth of a new technology and extended from xerography to online database systems. The implementation of the fair use and library reprography in Korean law to the local practices is examined on the basis of the new American copyright act of 1976. Under the draft revision of Korean law, librarians will face many potential problems as summarized below. 1. Because the new provision of 'life time plus 50 years' will tie up substantial bodies of material longer than the old law, until that date librarians would need permissions from the owners and should pay attention to the author's death date. 2. Because the copyright can be sold, distributed, given to the heirs, donated, as a whole or a part, librarians should chase down the heirs and other second owners. In case of a derivative work, this is a real problem. 3. Since a work has its protection from the moment of its creation, the coverage of copyrightable matter would be extended to the published or the unpublished works and librarian's work load would be heavier. Without copyright registration, no one can be certain that a work is in the public domain. Therefore, librarians will need to check with an authority. 4. For implementation of limitations on exclusive rights, fair use and library reproduction for interlibrary loan, there can be no substantial aggregate use and there can be no systematic distribution of multicopies. Therefore, librarians should not substitute reproductions for subscriptions or purchases. 5. For the interlibrary loan by photocopying, librarians should understand the procedure of royalty payment. 6. Compulsory licenses should be understood by librarians. 7. Because the draft revision of Korean law is a reciprocal treaty, librarians should take care of other countries' copyright law to protect foreign authors from Korean law. In order to solve the above problems, some suggestions are presented below. 1. That copyright clearinghouse or central agency as a centralized royalty payment mechanism be established. 2. That the Korean Library Association establish a committee on copyright. 3. That the Korean Library Association propose guidelines for each occasion, e.g. for interlibrary loan, books and periodicals and music, etc. 4. That the Korean government establish a copyright office or an official organization for copyright control other than the copyright committee already organized by the government. 5. That the Korean Library Association establish educational programs on copyright for librarians through seminars or articles written in its magazines. 6. That individual libraries provide librarian's copyright kits. 7. That school libraries distribute subject bibliographies on copyright law to teachers. However, librarians should keep in mind that limitations on exclusive rights are not for an exemption from library reprography but as a convenient access to library resources.

본고는 일본 현대연극이 가타리모노 셋교부시를 수용하여 어떻게 현대화했는가에 주목하여 작품을 분석하였다. 아울러 이를 통하여 '셋교부시에 의한 미세모노(見せ物)오페라' 장르로 탄생하는 과정을 밝히고자 하였다. 이와 관련해서는 중세의 스토리텔링 셋교부시를 현대적 '미세모노 오페라'로 재탄생시켰다는 점에서, 데라야마가 언그라 1세대들과 확연히 다른 점에 대해 논했던 종래의 평가들과는 또 다른 시각을 제시하고자 한다. 60년대 일본 언그라운동 1세대 데라야마 슈지(寺山修司)의 <신토쿠마루(身毒丸)>(1978년)는 서사적 이야기에 가락을 붙여 음송하는 가타리모노(語り物) 셋교부시(說經節) <신토쿠마루(俊德丸)>를 소재로 한 작품으로서, 동아시아 스토리텔링의 현대적 유산이라고 할 수 있다. 셋교 <신토쿠마루>는 계모의 저주로 나병에 걸린 신토쿠마루가 텐노지(天王寺)에서 약혼자 오토히메(乙姬)라는 여성의 헌신적인 사랑과 관음(?音)의 영력(?力)에 의해 구원되는 이야기이다. 데라야마 슈지는 셋교부시의 서사적 형식에 J.A.시저(シ?ザ?본명 寺原孝明)의 주술적인 락(rock)음악을 결합시키고 부제를 '셋교부시에 의한 미세모노 오페라(說敎節による見世物オペラ)'라고 하였다. 근원소재인 모자신 신앙(母子神信仰)의 원리로 보이는 '모도리(もどり; 회귀)' 본능의 중세적 종교 세계를 데라야마 슈지는 모자상간의 세계로 변화시킨다. 그리고 셋교부시에서 나타나는 보편적인 복수장면은 신토쿠마루가 계모인 나데시코(撫子)의 복장과 가면을 쓴 드래그 퀸(drag queen: 여장)의 모습으로 이복동생 센사쿠(せんさく)를 근친상간하는 것으로 복수한다. 이 작품은 셋교부시의 전형적인 인과 구조를 따르고 있고, 작품 전반에 개입하여 전체적 서사를 진행시키는 이야기꾼(語り手, 카타리테)과 야나기타 구니오(柳田國男)박사의 등장은 서사 장치인 자기소개 기법과 코러스의 현대적 활용을 보여준다. 특히 코러스 가사에서 데라야마 슈지의 불행한 어린 시절의 기억, 즉 아버지의 부재, 아오모리현(?森?)의 대공습 경험이 자동기술법처럼 묘사되어 내용을 심층화하고 있다. 이후 니나가와 유키오(?川幸雄)의 연출 버전은 초연 때부터의 공동 극작가였던 기시다 리오(岸田理生)가 데라야마의 사후 17년을 경과해 다시 쓴 개정판으로 데라야마 슈지의 원작 <신토쿠마루>를 널리 알렸다. 그러나 그의 연출 버전에서는 데라야마가 이 작품에 붙인 부제의 요소가 전부 삭제됨으로써 극단 연극실험실 '덴조사지키(天井?敷)'가 시도한 다양한 실험연극의 줄기와 본질로부터 벗어나 있다. <신토쿠 마루>는 현대연극의 서사구조를 갖고 있지만 각 단락이 독립적인 이야기를 구성하면서도 서로 유기적인 결합이 가능하도록 한 구조를 갖고 있다.

Today's public libraries in communities are on the processes of changes to integrate information and communication technology into traditional library system in order to support current users' demands for the new digital era. The purpose of this study is to examine the changing characters on space design and space uses of community based public libraries by conducting case studies of three branch libraries which were built after 2004 in Ann Arbor, Michigan in the United States. As the conclusion of this research, the findings of the case studies are utilized as basic data for planning and design guidelines for public libraries as community resources. The study summarizes the characteristics of space design and space uses in public libraries as follow; first, the floor plans of small-scale public libraries are open visually as well as spatially. The space organization of the libraries is arranged by potential noise levels, as placing noisy spaces near the entrance halls and quiet spaces at the back. Main book shelves are located in the middle of the library buildings, while seats are arranged along the window sides. By placing various kinds of furniture in open reading areas, library users can select different types of seats and tables for their comforts. Second. the survey of observation also finds that a large number of users often use library computers and personal computers to connect the internet at the libraries. These personal computer users who are new user group in community based libraries preferred to sit in casual study areas and individual tables with one or two seats only. Third, the libraries, in addition, develop and provide various programs and events for people in communities. Especially, the programs for children, the elderly and new comers from the abroad are well prepared, thus provide opportunities for them to visit the libraries in regular bases. The survey finds that family entertainment and leisure activities are the important parts of the program as well as renting music CD and movie DVD are also important reasons for people to come. Thus, the libraries prepare high quality children's space and CD shelves near the entrance hall.

Purpose - This study aims to investigate the success factors pertaining to K-POPs from an analysis of the internal business environment. Much research has investigated Korean Moves or how to popularize them. The research mainly focused on aspects of Korean Moves. However, few studies have attempted to examine Korean Moves or K-POPs from a managerial viewpoint. The current research tries to investigate the success factors of K-POP from strategic perspectives, specifically utilizing internal resource based view perspectives. It differentiates itself by looking at the competitiveness of K-POP from the internal resources. Research design, data, and methodology - In the entertainment industry, where creativity is heavily stressed, competitiveness is often regarded within the organization as a form of intangible asset, knowledge, or technology that is often related with the organization's personnel. Some research has tried to reveal the competitiveness of K-POP using Porter's competitiveness of nations framework. Others utilize the adapted model of Porter's structure. However, these models only look at the outside environment, and not inside a firm's resource, knowledge, or capabilities. This research utilizes the VRIO model to examine the internal resources and capabilities of K-POP producers. The model measures whether a firm's internal resources and capabilities are valuable, rare, difficult to imitate by competitors, or organizable. The research covered businesses whose yearly revenue exceeds $10 Million in music planning and recording in South Korea. There were only thirteen such companies (one percent of the total population). Of these, companies for whom 20 percent or more of the sales revenue comes from the abroad are targeted. Only seven are selected and these participated in the research. In order to find a firm's internal resources, we conducted qualitative research methodology. Their business names and persons who participated in this research are not revealed due to case sensitive issues. Instead, we use unrelated initials for their names and their statements. Results - From the in-depth interview with top-tier K-POP producers and managers, the current research tried to identify resources and capabilities that helped to strengthen their competitiveness. These resources and capabilities are sought from the scope of the VRIO model, which looks at the internal resources and capabilities from the scope of value, rarity, imitability, and organization. Interviews with the top tier producers and managers reveal the internal success factors of K-POPs. We conclude that these resources and capabilities are from internally accumulated producing know-how, unique managing (training) system, and outstanding all-round entertainment capabilities of the performers. Conclusions - These results indicate that the core resources and capabilities of K-POP are robust. It will take a significant amount of time and money to imitate for followers, because these resources and capabilities are the result of time investment and are embedded into producers' and performers' know-how. Taking Luo (2000)'s argument, K-POP is in the second stage of the globalization process, which is configuring and allocation resource capabilities to a global scope.

Purpose - This research examined the effect of hedonic and utilitarian eating-out motivations on the evaluation of restaurant selection attributes in a fashion premium outlet. Additionally, the influence of experimental and functional attributes on customers' preference for hedonic eating-out motives and utilitarian eating-out motives, and variation of moderating effects through the gender was examined. Research design, data, and methodology - A survey was conducted to verify the established research hypothesis. The questionnaire items for the research were modified to fit the situation of the present study. In order to elaborate the questionnaire, the literature of the previous researchers was reviewed and supplemented. The survey conducted 207 online questionnaires for consumers who have visited domestic fashion premium outlets from July 4, 2017 to July 27, 2017. A total of 207 questionnaires were collected, and a total of 206 questionnaires were used for the empirical analysis after excluding one inappropriate response. In order to verify the reliability and validity of the measured variables, exploratory factor analysis and reliability analysis were performed using SPSS 20.0. Next, the structural equation model (SEM) statistical method was used to test the hypotheses of the study. Results - Hedonic motivation had more influence on experimental attribute importance than the functional attribute importance of the restaurant. However, this result was different depending on the gender. The effects of hedonic motives on empirical attributes were more influenced by female groups, and when influencing functional attributes, male groups were more influenced. However, it was statistically significant (p <0.05) in the female group only when the hedonic eating out motives influenced empirical attributes. Conclusions - This study analyzed the effect of eating-out motivation on the restaurant preference attributes and suggested practical implications. First, customers with hedonic eating-out motivations were evaluating experiential attributes to be more important than functional attributes. Second, for customers who are motivated to use practical eating-out habits, companies should provide services that meet practical and economic needs. In particular, female customers visiting restaurants need differentiated marketing strategies that make them feel new experiences rather than practical ones. In addition, it is necessary to study more complex and integrated studies which will influence restaurant selection attributes of premium outlets customers by adding various eating out motives and selection attributes.
