도서관의 기본적인 목적은 지식의 생산 전달 및 사회에 대한 봉사이다. 도서관은 장서 및 정보봉사를 통해 이러한 목적을 달성하는데 기여하는 것이 필수적인 구성요소이다. 이런 목표를 달성하기 위해 장서의 질을 개선함으로써 이용자서비스의 질을 한층 더 향상시키기 위해 장서폐기가 필요하다. 하지만 현재 우리 도서관계에서는 장서 폐기의 중요성을 어느 정도 인식하고 있지만 회피하는 경향이 있다. 이러한 이유로 각 도서관별 장서의 양에 따라 도서관의 순위를 매기는 정책 요인과 실무 요인, 행정 요인 등이 있다. 결국 장서폐기에 대한 필요성은 인식하고 있지만 쉽게 실천을 못하는 실정이다. 장서폐기는 부족한 서고 공간 문제에 대한 해결책이 될 수 있을 뿐 아니라 장서의 품질관리를 위해서도 필수적인 활동이다. 따라서 장서폐기에 대한 필요성과 그에 따르는 저해요인을 분석함으로써 현실적인 도서관 관리를 재조명하고자 한다.

Organizational climate and organization culture can be some of the leading factors in hindering knowledge sharing within the organization. It is generally accepted that successful knowledge management practice, including knowledge sharing, comes as a result of a conducive and knowledge sharing friendly environment. Organizations that promote and reward collective work generate a trustful and a more collaborative learning culture. The perception of fairness in an organization has been considered an important indicator of employee behavior, attitude, and motivation. This study investigates organizational justice perception and its impact on knowledge sharing practices among forensic experts in the Turkish National Police. The study findings revealed that senior officers, who are experts in the field, have the strongest organizational justice perception. Meanwhile, noncommissioned officers or technicians bear positive but comparatively weaker feelings about the existence of justice within the organization. The study argues that those who satisfy their career expectations tend to have a higher organizational justice perception.

This study investigated the current status and characteristics of strategic alliances attempted by domestic internet businesses. Specifically, this study surveyed competitive environmental characteristics of partner companies involved, alliance period, types of partner companies, motives of alliances, types of alliances, success and failure factors and satisfaction toward the alliances. Major findings were: first, alliances between portal companies and content producers; portal companies and internet services; e-commercial sites and internet services were the most frequent partnerships engaged. Second, the most important motive for and type of the strategic alliance were: 'the commercialization and marketing of new product' and 'joint distribution and marketing agreement' respectively. Third, the most important factor for the successful alliance was 'a close examination of partners' core business value and competence'; and the factor most hindering the successful alliance was 'a discrepancy on capabilities of partners' core personnel. Finally types of internet business were significantly related to perceived satisfaction toward strategic alliance.

At present, the highest operation speed of general domestic train is in the level of 140km/h and it is being improved to reach at the level of 200km/h in 2011. The improved environment of train operation speed which inevitably occurs owing to the operation of KTX on the existing line badly requires technology development such as testing and evaluating technology of factors hindering high speed of railway infrastructure including railway bridge, technology to ensure operation safety and technology to evaluate structure stability. Comparing dynamic numerical interpretation for railway truss bridge and load of design standard by using dynamic response measurement and analysis for the railway truss bridge currently in use, this study established the improvement program to ensure the lateral dynamic safety of truss bridge with the increased speed of train.

As the world is rapidly changing into a knowledge-based information society, there is surprisingly increasing a great deal of knowledge. For this reason, various information systems have been constructed and operated to manage efficiently toward educational information resources. However, many different code systems are generally used for the lack of a standard management system. These different code systems have become significant factors hindering the efficiency of information co-ownership and practicability between each system. In this study, the author designed the Standard Data Code Management System and explored an efficient management program toward educational information resources.

Luteolin, a flavonoid present in several fruits, vegetables, nuts, and herbs reportedly exhibits anti-cancer and anti-inflammatory properties. However, the effect of luteolin on endometriosis, a painful condition characterized by the ectopic growth of endometrial tissue and pelvic inflammation, remains elusive. Herein, we observed that luteolin inhibited cell growth and induced apoptosis of 12Z human endometriotic cells by activating caspase-3, -8, and -9. Additionally, luteolin significantly inhibited the expression of key chemokines, C-C motif chemokine ligand 2 (CCL2) and CCL5, required for monocyte/macrophage influx at endometriotic sites. In macrophages stimulated by endometriotic cells, luteolin treatment suppressed the intracellular expression of M2 markers and endometriosis-promoting factors. Collectively, our data suggest that luteolin exerts anti-endometriotic effects by stimulating endometriotic cell apoptosis and hindering the alternative activation of macrophages.

Academic medicine is built from a foundation of education, research, and patient care. Since good patient care results from the application of medical research and continuous education, these three components cannot be separated for medical development to occur. In Korea, many obstacles hinder the achievement of academic medicine, such as an inefficient medical delivery system, limitations of primary care, low insurance prices, and no long-term health care plan. Medical education has changed to outcome-based education, but presented temporal integration status. Governance of healthcare research is not centralized, and Korea is awarded relatively fewer grants than other countries. Medical professors have reached a burnout state due to patient care responsibilities in addition to research and education duties. Many medical systems, including the medical delivery system and insurance problems, may contribute to distrust between doctors and patients. The government is not involved in a long-term health care policy. The multitude of factors mentioned here are hindering the achievement of academic medicine in Korea.

Sign-in point of interest (POI) are extremely sparse in location-based social networks, hindering recommendation systems from capturing users' deep-level preferences. To solve this problem, we propose a content-aware POI recommendation algorithm based on a convolutional neural network. First, using convolutional neural networks to process comment text information, we model location POI and user latent factors. Subsequently, the objective function is constructed by fusing users' geographical information and obtaining the emotional category information. In addition, the objective function comprises matrix decomposition and maximisation of the probability objective function. Finally, we solve the objective function efficiently. The prediction rate and F1 value on the Instagram-NewYork dataset are 78.32% and 76.37%, respectively, and those on the Instagram-Chicago dataset are 85.16% and 83.29%, respectively. Comparative experiments show that the proposed method can obtain a higher precision rate than several other newer recommended methods.

The purpose of this paper is to find out the present status of public library management. The assumptions on which this research is based are that there are differences between th theories taught at the educational institutions for librarians and the practices actually managed at libraries, and that the differences are greater in Korea than those in the United States of America as the former has a shorter library history and is a more bureaucratic society. The data were collected were collected through the questionnaires sent to fifty-five public library managers in Taegu and Kyungpook province. Forty-two respondents replied, making the returned rate of 76.4%. The results show that there exist some differences between theories and practices, but they are not so great as expected. It was found out that there is a difference between what the theorists state and what the practicing managers accept. It was also found out that the library managers agree that the new management theories and techniques can be adopted to their libraries. The hindering factors are found out, and based on the findings, a few suggestions are provided.
