When retrieving music with folksonomy tags, internal use of numeric tags (AV tags: tags consisting of Arousal and Valence values ) instead of word tags can partially solve the problem posed by synonyms. However, the two predecessor tasks should be done correctly; the first task is to map word tags to their numeric tags; the second is to get numeric tags of the music pieces to be retrieved. The first task is verified through our prior study and thus, in this paper, its significance is seen for the second task. To this end, we propose the music mapping table defining the relation between AV values and music and ANOVA tests are performed for analysis. The result shows that the arousal values and valence values of music have different distributions for 12 mood tags with or without synonymy and that their type I error values are P<0.001. Consequently, it is checked that the distribution of AV values is different according to music mood.

The authors reviewed research related to nursing organizational culture in order to determine the direction for future research, as well as the current status of nursing organizational culture. Research that analyzed nursing organizational culture were selected from journal articles in Korea and were reviewed. A total of 30 articles were collected. The number of studies on nursing organizational culture has shown a rapid increase since the late 1990s. Most research studies used a non-experimental design. The most frequently used organizational culture model and instrument was the competing values model defining culture pattern, which consists of relation-oriented, innovation-oriented, hierarch-oriented, and task-oriented culture. Other factors showing correlation with nursing organizational culture included job satisfaction, effectiveness, and so on. These results will be used to provide basic data for nursing leaders. In Korea, the next phase of research on organizational culture will require use of various approaches and research methods.

As the growth of database volume, it has required a need and an opportunity of data analysis and extracting knowledge from database. Data mining method is the representative example. The size of most minable data set is huge, and stored in a database. To implement effective mining function, we must extract minable data set to be analyzed from existing relational database, and it must be managed with its generalized information. In this paper, the new mining operator is defined in a similar manner to the existing SQL operators and SQL is extended to extract data subset from relations and to generalize it using domain-oriented method. The background knowledge includes attribute values, which will be mind and generalized information, and it is managed as the same structure with a relation in relational database. These functions are implemented by defining some SQL - like operators and aggregated functions, and we describe the expressive powers of these new operators and functions through examples.

In the fast growing digital environment, assuring continued authenticity is an essential and intransigent preservation consideration for digital data and records. Several key issues need to be addressed, including: What are electronic records and data?; Which intellectual and technical elements of data and records are essential for assuring authenticity in electronic format?; How should these be maintained and preserved over time?; How are authentic data and records used in various systems of practice?; and What are the best strategies of preserving authentic electronic records and data?. There have been many research projects to answer these questions to date. This paper discusses the characteristics of electronic records in light of preservation consideration and reports the activities and findings of some of the research projects in brief. This paper focuses on explaining the InterPARES (International Research on Permanent Authentic Records in Electronic Systems) Project, which is defining requirements for authenticity that can help develop strategies for long-term preservation in electronic records. To identify those requirements, more than thirty case studies have been conducted with government agencies, academic institutions, and various organizations in America, Canada, Europe, Asia and Australia and models developed for appraisal, preservation, and strategies in relation to the management of electronic records. The paper also suggests research questions and implications for preserving authentic electronic records as well as the encouragement for Korean research on digital preservation.

Recently, IoT technology is rapidly developing with the keyword "Anytime, Anywhere, Convenient". In addition, security problems in IoT systems are exploding and the damage is increasing as well. In this paper, we propose a method to develop IoT system safely by using internationally recognized CC evaluation in ICT by identifying the standardization and security technology development status defining IoT system security requirements. For this purpose, IoT system and service security aspects are analyzed. Based on this, it is possible to design the security functional requirements and to demonstrate the rationale of the security objective through the correspondence relation, and it is possible to design the protection profile for the IoT system. This is a sufficient basis for the development methodology to be presented in this paper because it is used as a means of referring to the set of security requirements of administrators, developers, and users.

Korea Digital Copyright Exchange of Korea Copyright Commission runs and manages copyrighted works and copyright license agreement, as well as assigns Integrated Copyright Number(ICN) to copyrighted works, also offers copyrighted works searching service. Keyword-based searching method based on ICN metadata provides results depending on the inclusion of metadata keyword. However, keyword-based searching method has limitations that cannot provide exact results that users need. Therefore, the essential method of offering exact result is needed. In this paper, we propose the semantic-based searching method about copyrighted works to increase the accuracy of searching results by extending ICN matadata to ontology, and implement the ontology of copyrighted works by defining relation and semantics about metadata elements. In order to compare semantic-based searching based on the ontology of copyrighted works with keyword-based searching method, the search results of each method according to 5 scenarios are presented and the accuracy of each method is compared.

It is very critical to specify certain medical personnels in defining the history of certain era. Due to the limited source of information and lack of thorough research, there still aren't enough study grounded on concrete historical investigation. Authors attempted to investigate those medicinal personnels engaged in Three Kingdoms period in terms of the activity area, relation with religion and their role in medical system and medical exchange. The sum of recorded medical personnels in Three Kingdoms period numbers 50 of which 6 belonged to Kokooryo, 18 to Baekje, 7 to Shilla and 19 to Unified Shilla. There might existed far more medical personnels who tried to alleviate the suffering of the people and were not recorded in the documents. The more earlier in times, the more medicine gets the religious tinge. This is not the exception for the period of the Three Kingdoms and those medicine men, wizard doctors and priest doctors were playing important role in healing people and processing crude drugs. The system of royal physician and medical education facility were established and doctors and pharmacists, shamanic doctor, herb collectors, Kongbong's doctor(供奉醫師), Kongbong's diviners(供奉卜師) took leads in medicine in those times. Those folkloric healers also took part in. Korea imported chinese medicine and Japan employed chinese medicine via Korea or directly from China and developed into traditional japanese medicine. In this process those who emigrated from Baekje and Kogooryo and their offsprings took an active part. Since the limited source of information of Three Kingdoms, we only can infer the me야cal environment of those times by featuring the activities of medical personnels.

The purpose of this study is searching for the problems and alternatives on teaching for repeating decimal. To accomplish the purpose, we have analyzed the fifth, sixth, and seventh Korean national curriculums, textbooks and examinations for the eighth grade about repeating decimal. W also have analyzed textbooks from USA to find for alternatives. As the results, we found followings. First, the national curriculums blocked us verifying the relation between rational number and repeating decimal. Second, definitions of terminating decimal, infinite decimal, and repeating decimal are slightly different in every textbooks. This leads seriously confusion for students examinations. The alternative on these problems is defining the terminating decimal as following; decimal which continually obtains only zeros in the quotient. That is, we have to avoid the representation of repeating decimal repeated nines under a declared system which apply an infinite decimal continually obtaining only zeros in the quotient. Then, we do not have any problems to verify the following statement. A number is a rational number if and only if it can be represented by a repeating decimal.

In this paper, we propose the role of job crafting in the relationship between leadership and organizational effectiveness in voluntarily carrying out each member's assigned tasks. This study surveyed the manufacturing, construction, service industries in Seoul and Gyeonggi province, identified the type of leadership they recognized, and empirically analyzed the organizational effectiveness of leadership. The purpose of this paper is to grasp the types of leadership acknowledged by the industry of manufacturing, construction, and service, and also to empirically analyze the organizational effectiveness of the leadership. The study measures the organizational effectiveness in terms of the job satisfaction, organizational commitment, and organizational citizenship behavior while classifying the leadership into coaching leadership, transformational leadership, and sensible leadership. In addition, the strictness of the analysis is imposed by estimating the simple least square model and ranking probit model. The results of the least square model is summarized as the following. Regardless of the different defining terms of organizational effectiveness, transformational leadership was shown to have the greatest organizational effectiveness. Sensible leadership positively effected job satisfaction whereas coaching leadership positively effected job satisfaction and organizational effectiveness. Compared to transformational leadership and coaching leadership, the impact of the sensible leadership was very much limited. The result of the ranking probit model is summarized as the following. First, sensible leadership had a positive impact on the member's job satisfaction and organizational commitment. Second, regarding the organizational citizenship behavior, coaching leadership showed greater impact than transformational leadership. This results contradicts the results from the simple least square model. If similar studies were to be conducted in the future, two models and the results must be compared. Third, as the leadership score increases by 1 point, there is greater possibility of having more than 4 points for all job satisfaction, organizational commitment, organizational citizenship behavior. Lastly, the analysis proves that job crafting has the mediation effect between the leadership and organizational effectiveness.

Background: Organizations are pursing complex and diverse aims to generate higher profits. Many workers experience high work intensity such as workload and work pressure in this organizational environment. Especially, psychological burden is a commonly used term in workplace of Republic of Korea. This study focused on defining the psychological burden from the perspective of occupational safety and health and tried to develop a scale for psychological burden. Methods: The 48 preliminary questionnaire items for psychological burden were prepared by a focus group interview with 16 workers through the Copenhagen Psychosocial Questionnaire II and Mindful Awareness Attention Scale. The preliminary items were surveyed with 572 workers, and exploratory factor analysis, confirmatory factor analysis, and correlation analysis were conducted for a new scale. Results: As a result of the exploratory factor analysis, five factors were extracted: organizational activity, human error, safety and health workload, work attitude, and negative self-management. These factors had significant correlations and reliability, and the stability of the model for validity was confirmed using confirmatory factor analysis. Conclusion: The developed scale for psychological burden can measure workers' psychological burden in relation to safety and health. Despite some limitations, this study has applicability in the workplace, given the relatively small-sized questionnaire.
