In this paper we introduce mathematical modellings in teaching and learning differential equations which were adopted by 2009 revised curriculum. The textbook of 'Advanced Mathematics II' published in 2014 with one publisher includes the content of the second order differential equation y"+y=0 by the power series method. This paper discusses the issue of the power series and gives an alternative method to explain problems of differential equation. Also, we found that the textbook of 'Advanced Mathematics II' used the mechanical system not electrical system in solving differential equation problems. Thus this paper suggests a method using an electric circuit in teaching and learning the first order differential equation. Finally we suggest some terminologies in the teaching and learning of differential equations.

Purpose: The purpose of this study was to identify the effect of interpersonal relation and job stress on nursing performance among male nurses. Methods: This study was cross-sectional descriptive one. The data were collected from self-administered questionnaires by 110 male nurses members affiliated with the Korean Man Nurses Association. The data were analyzed using descriptive statistics, independent t-test, one way ANOVA with Duncan test, Pearson correlation, and stepwise multiple regression with the SPSS/WIN 21.0. Results: The average scores of interpersonal relation, job stress, and nursing performance were respectively 3.64, 3.10, 3.63. Nursing performance was high in married, good health condition, manager, and high salary among male nurses. Nursing performance showed significant positive correlation with interpersonal relation (p<.001), and a significant negative correlation with job stress (p=.010). Influencing factors of nursing performance among male nurses were interpersonal relation, health status, total duration of career, position, and the adjusted $R^2$ of the regression model was 42%. Conclusion: The results suggest that we need to develop a training program to improve the nursing performance of the male nurses.

This paper proposes the design of a novel distributed message management scheme using a message-oriented management and analysis tool (MOMAT) for naval combat system (NCS) middle-ware. If a message is not guaranteed real-time of the NCS with each node, it causes the loss of data and decreases the reliability of systems. To solve these problems, improved message management schemes are proposed. Message management schemes are considering a real-time user management scheme and a real-time traffic management scheme. The proposed schemes are simulated with a developed simulation tool, data publisher, and subscriber connected through nodes in middle-ware. The simulation results show improved results in terms of message round-trip time (RTT), End-to-End delay, and throughput.

Authors, editors and reviewers, publishers, and subscribers all play their role in scientific journals. These 5 stakeholders are essential to journals. In this paper, firstly, I briefly summarize the role of each journal stakeholder and their respective goals. Secondly, the status of each participant in the Archives of Plastic Surgery is described. Finally, I propose an appropriate role and plan for each of them. Specific roles and responsibilities include the following: subscribers should welcome and submit the critiques of published papers in letters to the editor. Publishers should trust editors and provide them with adequate financial support for ongoing quality improvement of the journal. The editor-in-chief should be given a sufficient period of time-several years-to build up journal quality and train the incoming editor. The editors, including section editors, are also responsible for increasing the author pool. One editor might be designated a 'devil's referee', that is, a kind of devil's advocate with the responsibility of examining the originality of the manuscript, taking a skeptical view of the manuscript, and looking for holes in the methods and results of reported experiments. Authors' responsibilities include submitting manuscripts with scientific integrity and being ready to take responsibility for their articles even long after publication. Finally, reviewers' responsibilities include identifying similar articles not cited. Reviewers are also welcome to write a discussion on the article they review.

This research focuses on the cadastre and cartographic tradition regarding the representation of Rome that had lasted until the middle of 18th Century. Since the early period of Roman Republic until the early 18th Century, map was considered as a effective medium to record the status of urban facts and also a manifestation of changing perception of reality. These facts allow to diagnose social and conventional changes that had occurred in the field of representation techniques and methodologies derived from diverse intention and objective in elaboration of each map. Cartography also has affinity to architectural drawing as many categories of individuals are involved, clients, researchers, craftsmen, publisher and collectors. Fundamental task of documenting the contemporary physical reality was given to the map, however, as architects had practiced through the drawings, cartographers also reconstruct in subjective way specific buildings and urban aspects according to various needs and demands. As such, philology and imagination play important role as two constitute extreme poles in the evolution of the cadastre. Through analysis of paradigmatic examples in the genealogy of cartography of Rome, it was possible to understand the changing episteme that testify the mentality and custom in the field of visual representation.

Fashion reflects various cultures, including the spirit and the lifestyle of the period. South Korea has experienced rapid social changes, including the Korean War, industrial development, and the inflow of Western influence. Modern Korean fashion has developed along with these changes. Acceptance of suits and the reformism of the Hanbok are the two notable changes in Korean fashion. Gyungja Choi, and her fashion show, is known for combining modern fashion and traditional beauty by entwining traditional Korean fashion design elements into modern fashion. This research investigated Gyungja Choi as a fashion designer, a fashion education executive who cultivated fashion designers through the education business, and a fashion publisher who published the first professional costume magazine. This research classified the Korean-style design elements in Gyungja Choi's fashion show by analyzing the clothes exhibited in her fashion shows. In conclusion, Choi's design utilized Korean-style fashion design elements, such as line, colors, patterns, and materials. Which can be said to be the introduction period that expressed Korean style image in fashion considering the period.

To enhance network efficiency, CCN allow intermediate network nodes between a content consumer and a content publisher to temporarily cache transmitted contents. Then the network nodes immediately return back the cached contents to another consumers when the nodes receives relevant contents request messages from the consumers. For that, CCN utilizes hierarchical content names to forward a request message as well as a response message. However, such content names semantically contain much information about domain/user as well as content itself. So it is possible to invade users' privacy. In this paper, we first review both the problem of CCN name in the view point of privacy and proposed schemes. Then we propose an improved name management scheme for users' privacy preservation.
