In the social information facilities with physical stacks, it is critical to arrange categories of knowledge since there should be conventional methods by which users and visitors can browse index of all sorts of media relating to their topics. The classical index system of knowledge has been developed with primitive libraries and museums and therefore the system can be addressed by analyzing typical cases of precedents. As the forth industrial revolution has emerged, there will be quite innovative approach to provide information to the public as well as the private. The coalition between knowledge and space has always been considered as essential characteristics that remind scholars of hierarchical layout of knowledge resources such as maps, books, documents and diverse specimens. This research assumes that the spatial layout of knowledge can be classified in terms of physical attributes, symbolic entities, and information media and it defines what coalition between knowledge and space is creative in order to enacting interactive dialogue among information navigators. The spaces in between the knowledges function as trasition areas where the index system informs and stimulates, where the interface between the different knowledges is optimized and therefore the library as the public facilities no longer dedicated to the text, but as an information space in which all sorts of media are distributed equally.

Purpose: This study was undertaken to identify the mediating effect of family strengths in the relationship between e-learning readiness and learning management system-based online education learning outcomes. Our results provide basic data for proposing strategies to increase online education learning outcomes of nursing students. Methods: A self-report questionnaire was surveyed by 133 nursing students who took online education using a learning management system at three nursing colleges in Daejeon, Jeonbuk, and Gyeongbuk. The mediating effect of family strengths in the relationship between the e-learning readiness of the subject and online education learning outcomes, were analyzed by hierarchical multiple regression. Sobel test was performed to verify effectiveness of the pathway. Results: In the relationship between e-learning readiness and online education learning outcomes of nursing students, family strengths were determined to exert absolute mediating effect. Conclusions: Our results indicate that in order to improve e-learning readiness, the basic curriculum for nursing students should include web-based communication, cooperation, and the use of information technology, including interaction for online education. Improvements in family strengths can be achieved through home study activities, such as frequent conversations with members, monitoring achievements of the students, and sharing family leisure activities.

Broadcast encryption is a cryptographical primitive which is designed for a content provider to distribute contents to only privileged qualifying users through an insecure channel. Anyone who knows public keys can distribute contents by means of public key broadcast encryption whose technique can also be applicable to many other applications. In order to design public key broadcast encryption scheme, it should devise some methods that convert a broadcast encryption scheme based on symmetric key cryptosystem to a public key broadcast encryption. Up to this point, broadcast encryption scheme on trial for converting from symmetric key setting to asymmetric public key setting has been attempted by employing the Hierarchical Identity Based Encryption (HIBE) technique. However, this converting method is not optimal because some of the properties of HIBE are not quite fitting for public key broadcast schemes. In this paper, we proposed new converting method and an efficient public key broadcast encryption scheme Pub-PI which is obtained by adapting the new converting method to the PI scheme [10]. The transmission overhead of the Pub-PI is approximately 3r, where r is the number of revoked users. The storage size of Pub-PI is O($c^2$), where c is a system parameter of PI and the computation cost is 2 pairing computations.

A new statistical model needs additional variables in order to re-evaluate the undecided inference. Then the MNAR assumption is required, since the probabilities for the positivity of the indeterminant and the determinant is calculated differently. In this study, since two statistical models have a hierarchical relationship, we determine the undecided inference under the MNAR assumption using the confidence interval of the difference between two AUCs. Among many methods of estimating the confidence interval of the AUC difference, it is found that four kinds of methods show excellent performance through simulations. And based on these methods, we propose a variable selection method that are useful for the undecided inference using logistic regression models.

It is necessary to implement a wide range of housing welfare policies that citizens can experience in order to improve residents' the quality of life, as it emphasizes the balance of supply and management of public housing. The purpose of this study is to analyze the factors affecting residential satisfaction considering the three hierarchical levels of individual, household, and area. In the background of the study, the individuals' quality-of-life satisfaction determined not only by the individual but also by the various influencing environmental factors. This study targets 1,736 households, 3,239 persons in 464 areas in Seoul. The main research results are as follows. At the level one, there were influencing factors such as age(-), education level and income, and housing area per person, recipient of basic living(-), period(-) and RIR (at the level two). At the level three, west-south region(-) and social mix affect the complex of public housing. In consideration of living infrastructure, the closer to public transportation, public facilities, and medical facilities, the higher the satisfaction of public housing. The results of this analysis suggest that public support needs to focus on individual household members, but there is a need for ways to link it with the complex and the region.

We study confirmed the factors influencing the organizational culture(collective culture, development culture, rational culture, hierarchical culture) perceived by members of the organization and the manager's authentic leadership(self-awareness, balanced information processing, relational transparency, internalized moral perspective) on job crafting. In addition, the relationship between organizational culture and authentic leadership was empirically analyzed. In order to verify the hypothesis of the research model, the survey results of 269 parts were verified as follows using the statistical program of SPSS 24.0. First, the organizational cultures perceived by members of the organization, development culture and rational culture, showed positive (+) influence on job crafting. In other words, Hypothesis 1 established by the research model was partially adopted. Second, the group culture, development culture, and rational culture of organizational culture were statistically significant in the relationship between the hypothesis 2 organizational culture and authentic leadership. In other words, Hypothesis 2 was partially adopted. Third, the three hypotheses of authentic leadership (self-awareness, balanced information processing, relational transparency, and an internalized moral perspective) all showed positive (+) effects on job crafting. As a result of this study, it was possible to confirm the importance of the organizational culture that improves the job-crafting of the members of the organization and the strategic activation plan for authentic leadership. Therefore, the necessity of strategic human resource development for the development and application of programs to revitalize organizational culture and improve the manager's authentic leadership has emerged.

Purpose: The purpose of this study was to find out the suicidal ideation rate of the elderly including individual and regional factors by sex. Methods: This is secondary analysis study that combines the data of the 2017 Community Health Survey with the e-indicator data set of the National Statistical Office, and a descriptive correlation study. Statistical analysis used hierarchical logistic regression by SAS 9.4. Results: The 11.5% of the elderly had suicidal ideation within the last year, and 18.4% in Chungnam is the highest. Individual characteristics include females, older people, lower education levels, no job or housewife, no spouse, less than seven hours of sleep per day on the average, low subjective health, high subjective stress, and the worse their economic conditions, the more they had suicide ideation. Considering regional characteristics, suicidal ideation tended to increase significantly as the number of hospital beds per 1,000 people and the rate of obesity was lower, the rate of stress perception was higher, and the odds value was small. When both individual and regional factors were considered, the model conformity of the suicidal ideation improved (ICC=0.0814). Conclusion: In order to lower the suicidal rate of the elderly, it seems that both individual and community factors need to be comprehensively approached from the stage of suicidal ideation in the community.

This study examined the effect of regulatory focus on adaptative performance for pilots and co-pilots engaged in domestic civil airlines, and verified the moderating effect of organizational commitment in the process of regulatory focus on adaptative performance. For study, the scale developed by Lockwood Penelope and others validated and developed to measure the regulatory focus was adapted to suit the aviation scene and examined through this. As a result of the study, among the sub-variables of the regulatory focus scale, the promotion focus had a statistically significant and positive effect on the adaptative performance. and derived that the prevention focus had a statistically significant negative effect on the adaptative performance. In order to examine the moderating effect of organizational commitment in the relationship between regulatory focus and adaptative performance, the results of hierarchical regression analysis were conducted after controlling the rank, background, and career. Organizational commitment showed a statistically significant positive moderating effect in the relationship of adaptative performance. In addition, as a result of the verification according to the level of organizational commitment, prevention focus and adaptative performance showed statistically significant negative effects when organizational commitment was high.
