Due to COVID-19, user instruction programs could not be conducted face-to-face, and the sessions have been moved online. The present study attempted to investigate how online user instruction influences the information literacy ability of college students. The study randomly selected college students (N=50) who completed online user instruction sessions and college college students (N=50) who did not complete them among freshment who went to to college in 2020 to measure their information literacy abilities. For this study, a tool for measuring information literacy abilities was developed by referring to several previous studies. The measurement results were analyzed by the independent samples t-test, and significant differences were found between students who completed online user instruction sessions and those who did not. The findings of the study have confirmed that it is effective in enhancing library users' information literacy abilities to provide user instruction online under the COVID-19 situation, and even in post-COVID 19 times, which helps them appropriately utilize the characteristics of digital libraries. The information literacy measurement tool used in the present study was developed to evaluate online information literacy, and thus contributed to the extension of the literature of digital information literacy and user instruction.

$\Box$ 시장개요 o 독일 자동판매기 시장은 매출이나 수입, 수출량에서 큰 성장이 없다. 그러나 기존의 주를 이루던 음료, 스낵 자판기 이외에 다양한 자판기 물품 수요가 높아지고 있어 새로운 시장 개척의 기회가 되고 있다. o 자판기 시장의 대부분을 차지하는 음료, 스낵 자판기는 주로 사내에 비치되어 있다. 쉽게 거래처를 바꾸지 않는 독이 바이어 특성상, 기존 고객 유지와 신상품 개발이 주요 성공요인이 될 수 있다. o 자동판매기 시장의 특징은 담당 업체가 자판기 판매에서부터 지속적인 제품 조달 유지, 청소까지 맡게 된다는 점이다. 급격한 수요 증가가 예상되지 않는 한, 구매후의 서비스가 재구매 여부를 결정한다고 할 수 있다. $\Box$ 경쟁 동향 o 독일 자판기 시장에는 독일 제품과 더불어 프랑스, 네덜란드와 같은 주변 유럽국가의 제품들이 시장을 지배하고 있다. 대부분 한 업체에서 물품에 상관없이 다양한 자판기를 생산하고 있다. o 최근에는 선택의 폭이 넓은 복잡하고 다양한 자판기 제품이 인기를 끌고 있다. 박람회를 통해 선보이는 신상품에 대한 관심이 높아지고 있다. o 신선한 디자인과 다양해진 제품의 양이 새로운 구매 요소로 떠오르고 있다. 자판기의 위치 또한 중요한 변수가 되면서 좋은 위치 선점이 경쟁력 향상에 도움이 될 것으로 보인다. $\Box$ 마케팅 참고사항 o 자동판매기의 경우, 사업 파트너와의 협상이나 각각 상품에 따라 가격이 매우 유동적이다. 기존 시장에서의 기업 인지도 역시 가격 협상에 영향을 미치기 때문에 시장의 정확한 가격을 알아보기가 매우 힘들다. 자사의 가격이 곧 핵심역량을 나타내기 때문에 제3자에게 공개되는 일이 적다. o 독일에서는 우리나라와 달리 온라인 광고시장이 활성화되어 있지 않다. 자동판매기도 온라인 광고보다는 전문 잡지를 통해 광고한다. 올해에도 이런 경향은 지속될 것으로 보인다. $\Box$ 수출 시 참고사항 o 자판기 관련 제품의 독일 진출 시 현재까지 특별한 제약 사항은 없다. 관세는 1.7%이며 부가세는 다른 제품과 동일하게 19%를 적용 받는다. o CE 마크의 획득은 필수적이다. 독일 내 진출을 생각한다면 GS 마크를 획득하는 것도 도움이 된다.

This research is to find a direction of development through operating status survey of public library in Busan metropolitan city. First, Normally library users visit the library to check out books or to have a private study session. Also users normally obtained information about upcoming events done in the library through using offline search methods. Second, although the usage of the website was low, however the users demanded the increase in computer numbers in the library and online database for home access. Third, the users acknowledged the importance of the public library to their local community. Library policy indicator rated high in importance to the local community(m=3.86). However the reference desk(m=2.87), checkout desk(m=2.41), computer availability(m=2.47), as well as up-to-date artifact availability(m=2.64) did not reach the average point of 3.0. Thus, revealing that the public library's management policies were not sufficient enough to satisfy the needs of the library users.

For both customers and companies, it is very important to analyze online customer reviews, which consist of small documents that include opinions or experiences about products or services, because the customers can get good informations and the companies can establish good marketing strategies. In this paper, we propose the association model for the opinion mining which can analyze customer opinions posted on web. The association model is to modify the association rules mining model in data mining in order to apply efficiently and effectively the association mining techniques to the opinion mining. We designed and implemented the opinion mining systems based on the modified association model and the grouping idea which would enable it to generate significant rules more.

Although it is about a decade since public libraries started to provide digital information services, lack of expertise for efficient service operation and restrictions related to copyrights have led to failure to obtain remarkable performances in uses. This study intends to analyze operation cases of domestic and overseas collaborative digital information services, as well as the current status of digital information services of libraries in Gyeonggido, thereby developing a collaborative digital information service model among public libraries on the level of local governments. This research then analyzed collaborative digital information service Web sites and surveys. Based on the analysis result, this study presented support of integrated search of possessed electronic information, Web database (DB), DB on original texts of regional records, online reference services, and mobile platforms as functional factors to embody a successful service model. As a system management road map, an eclectic model combining the merits of centralized and decentralized models was found to be more effective than a centralized or decentralized model in consideration of the characteristics of participating organizations.

Libraries are founded to ensure the intellectual freedom of citizens, and citizens have the right to confidentiality regarding their needs, information access, and information use. Protecting users' privacy is critical to safeguarding their freedom of speech, freedom of thought, and freedom of assembly. Libraries and librarians should seriously concern themselves with their users' privacy because protecting this privacy is part of their most important mission, and, in doing so, users can truly enjoy their intellectual freedom. This study extensively investigated and analyzed the possibility of privacy invasion that may occur in libraries. As a result, cases of potential invasion of privacy in libraries were summarized in the following three categories: violations occurring in the process of national or law agencies' enforcement operations; violations occurring in the process of routine library services such as circulation, reference, online searching etc.; and violations occurring by outsourcing library services.
