The purpose of this study was to investigate the role expectation of Clinical Nurse Specialist(CNS) in A tertiary-affiliated hospital in Seoul. Data were surveyed from Jul. 8, to Jul. 20, 1996. 74 medical doctors and 119 nurses participated in this survey. For data analysis, SPSS/PC+ program was used: ${\chi}2-test$, t-test, ANOVA. The difference was analyzed by the subjects' position and department. The results of this study were summarized as follows: 1. The perception about the CNS system : Most of the subjects of study perceived that the introduction of CNS system was needed. And the introduction time of CNS system was demanded as fast as possible, or after special preparation. 2. The comparison of the need for the subroles of the CNS in A tertiary-affiliated hospital : The need for the subroles(0=not known, 1=not needed to 4=absolutely essential) was significantly different between medical doctors and nurses. The total mean scores for degree of need for each subole were as follows: Education 3.37, Consultant 3.34, Researcher 3.29, Direct care provider 2.86. 3. The comparison of the percent of time spent in A tertiary-affiliated hospital : The percent of time spent was significantly different between medical doctors and nurses. The total mean percent of time spent in the five subroles was as follows: Direct care provider 34.9%, Educator 23.9%, Researcher 18.9%, Consultant 12.8%, and Management/Change agent 9.5% According to the study results, suggestions were made: 1. Further study for the need of the CNS role as direct care provider is needed, after correcting the items within the narrow scope in some clinical department. 2. Development of the detail roles for the extent of autonomy is needed, and validity should be tested. And then they will be used for the basic data of the role development of the CNS.

본 논문에서는 IDC를 기반으로 한 FLV 동영상 솔루션을 Mini IPTV에 적용한 시스템 설계 및 구현을 제안한다. IDC의 에너지를 최소화하고, 자원 활용을 극대화시키는 Green Data Center로 설계하며, Mini IPTV의 다양한 콘텐츠를 서비스 공급자 및 네트워크 공급자가 네트워크를 통해 Mini IPTV 가입자에게 제공한다. 이때 FLV 솔루션 파일 포맷과 압축 기술을 이용해 동영상의 화질과 압축률을 개선하도록 구현함으로써, 트래픽 비용의 절감 및 보안 문제를 해결하고, 특히 웹에서 급속히 팽창하고 있는 e-Learning 분야에 활용하고자 한다.

In this paper, we place the focus on suggesting a method of forecasting demand for PCS resale service with survey data in Korea. It is important for the service provider to forecast the diffusion process when designing marketing strategies and analyzing the costs and benefits. For the reason, we conduct a survey of three groups composed of non-subscribers, cellular subscribers, and PCS subscribers in order to forecast the demand according to several possible scenarios and business strategies. We consider the survey item that is measured by multiple point scales in response to a question if he would subscribe to the mobile telephone service in the future. We propose a method to forecast the size of market potential by classifying each individual into the two extreme groups, that is, yes or no. Then, by integrating survey data and historical data, we forecast the demand for PCS resale service that varies according to scenarios and strategies. From the results, we can find several implications for the provider of PCS resale service.

크라우드센싱 시스템을 현실화하기 위해서는 서비스 제공자 서버와 사용자간의 신뢰도 구축이 선행되어야 한다. 서비스 제공자 서버는 지급하는 보상을 최소화하기 위해 센싱 데이터에 대한 평가를 조작할 수 있다. 또한 사용자는 부정한 보상을 얻기 위해 거짓 데이터를 제공할 수 있다. 본 논문에서는 크라우드센싱 시스템에 프라이빗 블록체인을 도입함으로써 서버가 제공한 보상과 사용자가 제공한 데이터를 불가변적으로 기록해 서버와 사용자가 서로의 감시자 역할을 하도록 한다. 또한 스마트 컨트랙트를 통해 센싱 데이터에 대한 평가를 자동화하고 그 과정을 사용자에게 공개하여 서버 신뢰도를 구축하는 방법을 제시한다. 성능 평가 및 타 시스템 비교를 통해 제안된 크라우드센싱 보상 시스템의 실현 가능성을 보인다.

본 연구는 의료서비스제공자의 언어·비언어커뮤니케이션이 라포를 매개하여 고객만족에 미치는 영향을 파악하고, 지각된 서비스진정성을 조절 효과로 하여 라포에 미치는 영향 정도를 알아보기 위해 자가 보고식 설문 조사법을 이용한 서술적 조사 연구이다. 자료수집 기간은 2021년4월5일부터 4월30일까지 였다. 편의표본추출법을 사용하여 부산광역시 및 경상남도에 소재하고 있는 의료기관을 이용한 이용객을 대상으로 하여 자료를 수집하였으며 총 306부의 유효설문지를 통계분석 자료로 이용하였다. 수집된 자료는 코딩 과정을 거쳐 IBM SPSS statistics version 25.0 및 AMOS 20.0 프로그램을 이용하여 분석하였다. 본 연구결과에서 의료서비스제공자의 언어·비언어커뮤니케이션이 라포를 매개하여 고객만족에 영향을 주고, 각 변수 간 관계에서 지각된 서비스진정성이 조절효과로써 작용 작용한다는 것을 알 수 있었다. 의료서비스제공자와 병원이용객 간의 상호작용에서 의료서비스제공자의 언어·비언어적 요소가 중요하고 이러한 요소가 라포와 고객만족에 영향을 미친다는 점을 고려해 볼 때 의료서비스제공자는 병원이용객에게 서비스를 할 때 언어·비언어적 요소를 충분히 고려하여 진정성 있는 태도로 임해야 하며, 의료기관에서도 종사자와 병원이용객이 의사소통을 원활히 하여 상호만족 할 수 있도록 관련 직무교육을 통해 돕도록 해야 할 것으로 판단된다.

This paper analyzes the main factors affecting user selection of a small-sum electronic payment system using survey data of 396 users. Several findings emerge. First, users consider three pillars and eight factors in adopting a new system : system features(stability, security, and flexibility), transaction cost(payment commission and settlement period), and financial capability of provider(stability of financial structure, risk management capability, and funding capability). Second, the stability of the financial structure of the system provider is the most important factor to user acceptance of a new e-payment system. Users tend to consider uncertainty risk more seriously than transaction cost. This reflects the reality that electronic payment system service industry has not fully fledged yet. Third, some moderating effects exist according to payment methods and business usages. As for payment methods, speedy settlement cycle for wired/wireless phone payment, system stability for credit card and account transfer payment, and security for advance payment means are crucial factors. As for business usages, the stability of financial structure for online game content, system stability for music and video content, proxy payment commission for e-learning content, flexibility of the payment system for digital adult content, and security for public services are decisive ones.

Objectives : The purpose of this study is to investigate the knowledge and attitude toward cardiopulmonary resuscitation(CPR) in some dental hygienists. Methods : A self-reported questionnaire was filled out by 207 dental hygienists in Gwangju from February to March, 2014. The questionnaire consisted of knowledge and attitude toward CPR dental hygienists. The data were analyzed using IBM SPSS 19.0 program for chi-square test, independent t-test, one-way ANOVA and multiple regression analysis. Results : Dental hygienists having basic life support(BLS) provider accounted for 16.9%. CPR knowledge was 8.40 and attitude was 3.59 points. There were positive correlations between CPR knowledge and attitude including education, performance, and confidence(r=.231, r=.207, r=.377). In the regression analysis, attitude toward CPR confidence were positively associated with BLS provider certificate within two years. Conclusions : Dental hygienists had low level of knowledge and confidence toward CPR. It is important to educate BLS provider course to the dental hygienists.

This paper was tried to show the improvement model for software industry structure in Korea regarding to have the global level of competence in Korean software firms. To suggest the improvement model for software industry structure, the detailed status about software industry which as in the supply and demand perspectives and comparativeness dimension were analysed. Also to this model the special survey results from the 35 professionalists in the software industry were included. This improvement model suggests the big software firms have to consider the economy of the scale, and to enter global IT market, the other SMEs have to pursuit themselves as a specified technology firms. So it is good for the oversea project collaboration with the solution provider firms and IT service firms. And it is desirable to make a the economy of scale regarding as the solution venture startup, M&A, networking the software firms as supply chain. Also the development of new business model for new market and firms with the high-tech business competency will be required.

Windows 운영체제는 응용프로그램이 쉽고 편리하게 다양한 암호화 알고리즘을 사용할 수 있도록 CSPs(Cryptographic Service Providers)를 제공하고 있으며, 이 응용프로그램은 CryptoAPI(Cryptographic Application Program Interface)를 통하여 선택적으로 다양한 CSP 모듈을 이용할 수 있다. 이 때 CryptoAPI와 CSP 모듈 사이에서 함수로 전달되는 파라미터의 분석을 방지하기 위해 핸들을 이용한 안전한 데이터 접근 방식을 사용하고 있다. 본 논문에서는 새롭게 제시한 메모리 역추적 기법을 통해 위와 같은 보안기법에서도 개인키/비밀키와 같은 중요한 데이터가 노출되는 취약점이 존재한다는 것을 실험을 통해 증명하였다.
