According to the results from the recent research in Business field, the correlation between customer satisfaction and customer loyalty is not strong. Based on this understanding, the first purpose of this study was to investigate the correlation between public library service user satisfaction and public library service user loyalty. To achieve this purpose, the study conducted a survey of 240 public library users. The findings of this study are 1) the correlation between 'public library service user satisfaction' and 'public library service user loyalty' exists. However the strength of the correlation is moderate, 2) the correlation between 'public library service user satisfaction' and 'public library service users' intention to use new library services' is the weakest among the variables of 'public library service user loyalty', and 3) the correlation between 'public library service user satisfaction' and 'public library service users' intention to recommend library services to others is the strongest among the variables of 'public library service user loyalty'. The second purpose of this study was to find the moderator variables between public library service user satisfaction and public library service user loyalty. According to the study results, the following moderate variables are found: 1) physical accessibility, 2) lack of diversity in library service, 3) car-parking issues, 4) lack of diversity and recency in collections, and 5) lack of convenience in facilities.

Objective: This study was conducted to estimate the temperature and microbial changes of corn silages during aerobic exposure. Methods: Kwangpyeongok (KW) and Pioneer 1543 (PI) corn hybrids were harvested at 29.7% of dry matter and chopped to 3 to 5 cm lengths. Homo (Lactobacillus plantarum; LP) or hetero (Lactobacillus buchneri; LB) fermentative inoculants at 1.2×105 colony forming unit/g of fresh forage was applied to the chopped corn forage which was then ensiled in quadruplicate with a 2×2 (hybrid×inoculant) treatment arrangement for 100 days. After the silo was opened, silage was sub-sampled for analysis of chemical compositions, in vitro digestibility, and fermentation indices. The fresh silage was continued to determine aerobic exposure qualities by recorded temperature and microbial changes. Results: The KW silages had higher (p<0.01) in vitro digestibilities of dry matter and neutral detergent fiber than those of PI silages. Silages applied with LB had higher (p<0.001) acetate concentration, but lower (p<0.01) lactate concentration and lactate to acetate ratio than those of LP silages. The interaction effect among hybrid and inoculant was detected in acetate production (p = 0.008), aerobic stability (p = 0.006), and lactic acid bacteria count (p = 0.048). The yeast was lower (p = 0.018) in LB silages than that in LP silages. During the aerobic exposure, PI silages showed higher (p<0.05) temperature and mold than KW silages, while LP silages had higher (p<0.05) lactic acid bacteria and yeast than LB silages. Conclusion: The results indicated that the changes of silage temperature during aerobic exposure seems mainly affected by mold growth, while applied LB only enhanced aerobic stability of PI silages.

본 연구의 목적은 IPA분석 기법을 기본으로 이를 확장 적용하여 공공도서관 사서의 직무를 심도 있게 이해하는 데 있다. 연구 목적 달성을 위해 사서들을 대상으로 설문조사를 실시하였으며 그 결과를 토대로 수행직무에 대한 중요도, 전문성, 난이도, 노동강도, 직무비중 등을 교차 분석했다. 분석결과 ‘문헌정보조직’, ‘독서문화프로그램 계획 수립’, ‘도서관 사업 운영 관리’ 직무는 중요도, 난이도, 전문성, 노동강도가 모두 높은 직무로 인식되고 있었으며, ‘문헌정보 서비스 마케팅’, ‘문헌정보 수집 정책 개발’은 노동강도는 낮지만 중요도, 난이도, 전문성이 높은 직무로 인식되고 있었다. 이러한 직무는 사서의 전문지식과 역량이 요구되는 중요한 직무라는 의미로 이해할 수 있다. 한편, ‘문헌정보 시스템 구축’, ‘문헌정보 시스템 운영’, ‘도서관 정보센터 경영 관리’, ‘도서관 유관기관 협력’, ‘전자문서 정보관리’, ‘이용자 교육’은 중요도, 난이도, 전문성, 노동강도가 모두 낮은 직무로 나타났다. 이러한 직무분석 결과는 사서들을 위한 직무설계와 교육 및 훈련 계획을 마련하는 데 기초자료 역할을 할 수 있을 것으로 기대한다. The purpose of this study is to gain an in-depth understanding of the duties of public librarians by expanding and applying IPA analysis. A survey of librarians was conducted to achieve this research goal. The survey results were used to conduct a cross-analysis of the importance, profession, difficulty, labor intensity, and job weight of performed tasks. The analysis revealed that the tasks of “Library Materials Organization,” “Planning of Reading and Cultural Library Programs,” and “Library Operations Management” were perceived as having high importance, difficulty, profession, and labor intensity. “Library Services Marketing” and “Developing Library Collection Policies” were perceived as having low labor intensity but high importance, difficulty, and profession. These tasks require the librarians’ specialized knowledge and skills, highlighting their importance. On the other hand, tasks such as “Building Library Systems,” “Operating Library Systems,” “Managing Library Information Centers,” “Cooperation with Related Library Organizations,” “Electronic Information Management,” and “User Education” were identified as having low importance, difficulty, profession, and labor intensity. The results of this job analysis are expected to serve as a foundation for designing job roles, planning education, and training for librarians.

This study aims to analyze the Big Data-related research trends in thefield of public library by using the social network analytical method. One hundred seventeen articles published in the journal ‘Public Library Quarterly’ were analyzed with author keywords and the frequency, degree centrality, while the betweenness centrality of the keywords were examined. The keywords “programs” and “community development” demonstrated the highest degree of centrality. The keywords “programs”, “strategic planning”, “community development”, “future of libraries”, “outreach”, and “evaluation” posted a high degree of centrality and betweenness centrality. The keywords “measurement”, “survey”, “community partnerships”, and “community engagement” demonstrated a high degree of centrality but not a high betweenness centrality. Meanwhile, the keywords “planning”, “marketing”, “community needs”, and “community building” demonstrated a high betweenness centrality but not a high degree centrality. Based on the results of this study, public libraries should focus on the following directions of research when focusing on the Big Data. First, as mentioned in the above, a more in-depth discussion is needed regarding COVID-19 and social media. Second, the academic interest in the Big Data related education and training for the public librarians and educational contents is needed. Third, public libraries should think about the ways to efficiently perform their roles as a local data center, including their cooperation with other organizations in their local community.
