Recently, the importance of big data has been increased, and demand for data analysis for the big data is also increased. R language is developed for data analysis, and users are analyzing data by using algorithms of various statistics, machine learning and data mining packages in R language. However, it is difficult to develop an application using R. Early study proposed a method to call R script through another language such as PHP, Java, and so on. However, it is troublesome to write such a development method in addition to R in combination with other languages. In this study, we introduce how to write API using only R language without using another language by using Plumber package. We also propose a solution for security issues related with R API. If we use propose technology for developing web application, we can expect high productivity, easy of use, and easy of maintenance.

전력기술 연구개발 과정에서 R&D 소프트웨어 개발이 연구의 목적으로써 또는 수단으로써 상당한 역할과 비중을 차지하고 있으며 이러한 경향은 더욱 강화되고 있다. 또한, 전력기술 분야와 특성 및 기능에 따라 개발되는 R&D 소프트웨어가 다양하고 이에 적용되는 S/W 개발언어도 여러 종류가 사용되고 있다. 그러나, 이제까지 전력기술 연구개발과 관련하여 수많은 R&D 소프트웨어가 개발되고 있으나 연구개발 분야와 특성에 따라 적용된 S/W 개발언어에 대한 연구가 없었다. 본 논문에서는 주요 프로그래밍 언어별 특징을 알아하고, 전력기술 연구개발 과정에서 개발된 R&D 소프트웨어 현황 및 S/W 개발에 사용된 프로그래밍 언어를 파악하고자 한다. 또한, 전력기술 분야 및 기능에 따라 적용된 R&D 소프트웨어 개발언어의 특성을 분석하고, 향후 전력기술의 분야 및 기능에 따라 개발되는 소프트웨어의 프로그래밍 언어 선택 방안을 제시하고자 한다.

통계 소프트웨어 R은 여러 가지 특징을 가진 도구이다. S라는 전산언어를 기반으로 하고 이에 수학함수와 통계함수, 그리고 그래픽함수들이 결합되어 편리한 계산 작업 환경을 제공하고 있다. R이 기반으로 하고 있는 S언어에는 문법적, 의미론적 특징이 잘 어울려 있다. S언어의 주요 특징 중 하나는 객체지향성이다. 본 연구에서는 R의 특징인 객체지향성과 그 의미에 대하여 살펴보게 된다.

최근 IPTV 상용화와 디지털 방송 본격화는 사용자에게 다양한 방송 프로그램을 제공한다는 장점도 있지만, 동시에 수많은 프로그램을 탐색하여 선별해야 하는 부담을 주고 있다. 이러한 불편함을 해소하고자 최근에는 사용자 선호도와 방송 프로그램 정보를 이용하여 사용자 취향에 맞는 프로그램을 자동으로 추천하는 서비스의 요구가 증대되고 있다. 또한 궁극적으로 방송 서비스가 '개인화'와 '개방화'의 형태로 진행되고 있다는 점을 감안하면, 추천 서비스는 TV 프로그램 뿐만 아니라 광고도 포함해야 하며, 다중 언어를 지원하는 형태로 발전되어야 한다. 본 논문에서는 다중 언어를 지원하는 개인화된 TV 프로그램 및 광고 추천 서비스를 위한 하나의 시스템을 제안한다. 우리는 먼저 사용자 시나리오를 작성하고, 기능 요구사항들을 분석하여 시스템 구조를 설계한다. 그리고 다중 언어를 지원하는 시스템에서의 한글 처리 방법도 간단히 설명한다. 본 연구는 현재 유럽 공동기술 개발 사업 과제의 일환으로 진행되고 있어, 여기에서는 현 시점의 결과물인 시나리오, 시스템 구조 설계, 한글 처리까지 소개하고 있다.

This study was conducted to investigate experiences, convergent responses and expected negative impacts of verbal abuse of 253 paramedic students when they were doing clinical training practice. The results were as follows. First, 34%(86 people) experienced verbal abuse, the most frequently verbal abuse was done by Patients and Patient's family. Second, the most frequently contents of verbal abuse by Patient and Patient's family, Paramedic, Doctor and Nurse was 'Talking down or rude talk to me'. Third, the most frequently emotional responses of the students was 'Angry' and coping was 'Tolerate'. Fourth, the most frequently expected negative impacts was 'Practice productivity will be compromised'. Fifth, when experiencing verbal abuse by Paramedic was correlated with emotional responses(r=.458 p=.000), emotional responses was correlated with stress and expected negative impacts(r=.553 p=.000, r=.540 p=.000). In conclusion, it will be necessary to provide preventive education on verbal abuse before clinical training practice and to take active measures that have been protocolized.

The purpose of this study was to evaluate the relationship among verbal violence experience, verbal violence impact and burnout of operating room nurses. The data were collected by structured self-reporting questionnaires from 202 operating room nurses and were analyzed with descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and multiple regression. The level of verbal violence experience and verbal violence impact was 1.96 and 1.67. The level of burnout was 3.08. Verbal violence impact and burnout have a significant positive association with verbal violence experience(r=.39, p<.001; r=.41, p<.001). Verbal violence impact was positively associated with burnout(r=.29, p<.001). Factors influencing burnout were verbal violence experience, verbal violence impact and position(staff nurse) which explained 30% of the variance(F=9.15, p<.001). These findings indicate that verbal violence experiences of operating room nurses have influence on stability and productivity in personal, social aspect and suggest developing the verbal violence prevention program in hospital.

소비자들이 원하는 제품의 감성을 언어로 표현하여 줄 때, 이를 퍼지추론하여 칼라를 선택해주는 시스템을 개발하였다. 시스템은 감성언어입력, 감성언어퍼지화, 칼라추론, 추론규칙, 출력 등 모두 5개 의 모듈로 구성되어 있다. 시스템은 감성언어를 색상, 채도, 명도로 변환시킨 후 이를 다시 R, G, B 값으로 변환시키게 된다. 이때, 색상, 채도, 명도로의 변환에는 퍼지화규칙이 사용되게 되며, R,G,B 값으로의 변환 에는 칼라추론규칙이 사용되게 된다. 퍼지화규칙을 만들기 위해 S.D.(의미미분)법에 의한 감성언어의 요인 분석을 실시하였으며, 동시에 문헌조사를 통해 얻은 칼라와 관련한 감성정보를 if-then 규칙 형태로 시스템에 구현하였다.

Objectives: This study was conducted to investigate the degree of verbal abuse, emotional response, nursing professionalism, clinical practice stress during clinical practicim of nursing students. Methods: A sample of convenience was 106 nursing students, and a questionnaire was used to measure their verbal abuse, emotional response, nursing professionalism, clinical practice stress. Data were analyzed by descriptive statistics, t-test, one-way ANOVA, and multiple linear regression. Results: A significant positive correlation was found among verbal abuse, emotional response, clinical practice stress(r=.683, r=.573). Grade of which the participant was in, verbal abuse(𝛽=.487), emotional response(𝛽=.240) were significant predictive variables of which accounted for 49% of the variance in clinical practice stress. Conclusions: The results from this study can provide basic data on the development of strategies for nursing college students to cope with verbal abuse and to manage stress under clinical practice

It is required for nurses to have a high quality nursing knowledge and an excellent nursing performance ability to provide high quality nursing. It is natural for nurses to be exposed on verbal abuse due to the relations among various experts, patients and their families. Verbal abuse is one of the major factors that has affect on not only takig care of patients but also nursing performance. Nurses exposed by verbal abuse tended to respond negatively and undergo a lot of stress. The purpose of this study was to identify relations among nurses verbal abuse, psychosocial stress, and nursing performance. This study shows that verbal abuse was not related to nursing performance(r=-.099, p=.146). The performance of nurses has positive correlation with verbal abuse and psychosocial stress(r=.234, p<.001) and negative correlation with psychosocial stress and nursing performance(r=-.254, p<.001). It is requested for the study of the development and validation of a program reducing psychosocial stress to improve nursing performance.
