The purpose of this study was to identify the relationship between problem solving ability, critical thinking disposition, creativity and nursing process competence of nursing students. The participants in the study were 246 nursing students enrolled in 2nd year of a BSN program in S city, Korea. Data were collected from June 10 to June 20, 2015 using a structured questionnaire. Relationship between general characteristics and solving ability, critical thinking disposition, creativity and nursing process competence was analyzed by t-test, ANOVA and Kruskal-wallis. Correlation among problem solving ability, critical thinking disposition, creativity and nursing process competence was analyzed by pearson correlation coefficient. There was a statistically significant difference in problem solving with the reason for application, major satisfaction. There was a significant positive correlation between problem solving ability, critical thinking disposition, creativity and self efficacy. Nursing process competence was't a significant between problem solving ability, critical thinking disposition, creativity and self efficacy. These findings show that there is a need to develop strategies to improve self efficacy and nursing process competence for student nurses.

The purpose of this study was to verify the effects of growth orientation, life satisfaction, perceived stress, positive psychological capital and interpersonal relationships in the group coaching program for the promotion of growth orientation for university students based on the model of the social-cognitive approach to motivation. The program consisted of eight topics: growth orientation, growth mindset and brain plasticity, self-directed goal setting, talent which is a product of ongoing effort, failure attitude and perspective change, positive emotion, thinking and behavior, value of growth orientation and self-coaching, respectively. The program comprised a total of eight sessions, 120 minutes each, and the final program was completed through a preliminary experiment with three university students. In order to verify the effectiveness of the program, 48 university students were divided into 16 in the experimental group, 16 in the comparative group, and 16 in the control group. The experimental group participated in the group coaching program to enhance the growth orientation based on the model of the social-cognitive approach to motivation developed in this study, the comparative group participated in a learning goal orientation improvement program based on an incremental implicit theory, and the control group did not carry out any program. Three groups were tested in pre, post, follow-up1(after 1 month) and follow-up2(after 3 months) in order to growth orientation, life satisfaction, perceived stress, positive psychological capital and interpersonal relationships. We performed analysis to confirm the homogeneity to the data of the three groups and to verify the interaction effects between times and groups. As a result, it was confirmed that the group coaching program to promote growth orientation, life satisfaction, perceived stress, positive psychological capital and interpersonal relationships had statistically significant effect and was more effective than the comparative program due to the larger effective size. Also, we confirmed that the coaching effect was sustained after the program was finished and more effectively maintained than the comparative program. Based on the results of this study, this study has academic implications because it verify the effectiveness of the group coaching for the promotion of the growth orientation by scient ic method.

데이터 통합은 기업의 각 조직과 주요 업무, 핵심 애플리케이션에서 발생하는 물리적인 데이터 소스들을 표준 규칙과 메타데이터에 여과시켜 중복성을 제거하고. 오직 데이터 통합 및 단일 뷰를 정확하게 제공하기에 어려움이 따른다. 특히, 이기종 시스템이나 다양한 애플리케이션에서 나오는 대량의 데이터를 종류와 형식에 관계없이 호환이 가능하도록 지속적으로 통합하여, 정확한 정보를 실시간으로 동기화하여 제공할 수 있는 자동화된 정보의 통합이 관건이다. 따라서 본 논문에서는 레거시 시스템간의 데이터를 협업할 때 실시간으로 변화는 데이터를 일관성 있게 유지하기 위해서 데이터 협업 메커니즘을 제안한다. 또한 XMDR을 이용하여 협업에 의한 데이터 통합에서 발생하는 의미적 상호 운용성의 문제점을 해결하는 XMDR 기반의 데이터 허브 시스템을 구축한다.

최근 무선 통신 기술과 전자 기술의 진보로 지능형 센서(Smart Sensor)를 이용한 무선 센서 네트워크 구축이 가능해졌고, 이러한 센서 네트워크는 최근 유비쿼터스 컴퓨팅과 Ad-Hoc 네트워크에서 많이 연구되고 있는 새로운 이슈이다. 최근 센서관련 논문에서는 각 센서 노드의 제한된 에너지를 효율적으로 사용하기 위해 데이터 전송이 없을 경우 노드의 통신 모듈을 Sleep 시킴으로써 에너지를 절약 한다. 이를 위해서 모든 센서 노드들은 동기화를 맞추어 listen과 sleep를 주기적으로 반복해야 한다. 이러한 프로토콜들에서 발생하는 가장 큰 문제는 에너지 효율성과 데이터 전송 지연간의 반비례 관계이다. 에너지의 효율성을 위해 Sleep 시간을 길게 할수록, Sleep 시간에서 발생한 데이터의 지연 시간도 길어지게 되므로, 데이터의 지연을 고려하여 sleep 시간을 적당히 조정해야 필요가 있다. 본 논문에서는 에너지 효율성을 위해 listen/sleep 주기를 사용하면서도 데이터 지연을 최소화 할 수 있는 효율적 sleep 시간에 대해 논의 해 보려 한다.

최근 무선 통신 기술과 초소형화 기술의 진보로 지능형 센서(Smart Sensor)를 이용한 무선 센서 네트워크 구축이 가능해졌고, 이러한 센서 네트워크는 유비쿼터스 컴퓨팅와 Ad-Hoc 네트워크에서 많이 연구되고 있는 새로운 분야이다. 각 센서 노드는 건전지를 통해 전원을 공급받기 때문에. 제한된 에너지를 어떻게 효율적으로 사용하느냐가 센서 네트워크에서의 중요한 이슈이다. 일반적으로 센서네트워크에서 데이터 송수신에 참여하지 않는 노드는 일정 시간 Sleep함으로써 에너지를 절약한다. sleep 기술과 관계된 기존의 논문(S-MAC [1])에서는 동기화 및 NAV 설정을 위해 컨트롤 패킷(SYNC, RTS, CTS)을 사용하고, 컨트롤 패킷 전송 시간만큼은 최소한 모든 노드들이 깨어서 컨트롤 패킷의 송수신을 확인해야 한다. 본 논문에서는 컨트롤 패킷 전송 시간 동안 불필요하게 모든 노드들이 깨어있는 문제를 해결하기 위해, 새로운 센서 MAC 프로토콜(ESMAC: Efficient Sensor MAC)을 제시한다. ESMAC에서는 컨트롤 패킷 전송 시간동안 꼭 필요한 노드들만 컨트롤 패킷을 송수신하고, 나머지 노드들은 Sleep 함으로써, 모든 노드가 깨어있는 시간을 효율적으로 줄였다. 위와 같은 방법을 사용하여 ESMAC에서는 기존의 MAC(SMAC, TIPS [2]) 프로토콜들보다 컨트롤 패킷 전송 시간을 최대 62.8% 절약시켰다.

Based on theoretical background of Situational Theory of Problem Solving(STOPS), we have examined the role of STOPS variables on a group of online public in their issue recognition and communicative behavior on Korea's nationwide civil boycott movement of Japanese goods. Results from 524 survey cases from a Korea's major online community show that two independent variables(Problem Recognition, Referent Criterion) revealed positive in their effect on mediating variable(Situational Motivation in Problem Solving). Situational Motivation also revealed positive in its effect on six dependent variables(Information Forefending, Information Permitting, Information Forwarding, Information Sharing, Information Seeking, Information Attending) of Communicative Behavior. Involvement Recognition and Constraint Recognition revealed positive without proper statistical significance. As a result, study on the case of online public in Korea supports STOPS theory as high-level of Problem Recognition and Referent Criterion effects on Communicative Behavior in positive way via Situational Motivation. Implications from the findings have discussed and proposed suggestions for government public relations and further studies.

The personality types has been emphasized as one of the influential factors for the program selection by viewers in the multi-channel and multimedia era. However, there have been few empirical studies on this issue. The current study investigated how the audience personality influence the program preference. Specifically, this study focused on both need for cognition and sensation seeking which are related to the television viewing motivation. To examine the influence of personality on program preference, four types of drama and five types of entertainment programs were used. The results of the web survey showed that viewers personality type seem to have effect on their program preference. Indeed, it appeared that there was positive relationship between need for cognition and sensation seeking. The implications of this study's findings were discussed.

The study demonstrably begins with the franchise system that found management of member store for office, the satisfaction that the relation between main office and member store and the difference with renewal of the contract. According to the result of the study that analyzed the difference in the rate of satisfaction that depended on individual peculiarities, the study found the statistical difference in a part of a category of business, a school career, a business career, a floor area, a selling level and presence of experience. The floor area and the selling level are distributed into 3 groups and the category of business, the school career, the business career and presence of experience are distributed into 2 groups. In addition, the result that analyzed the difference in the rate of satisfaction that depended on the motive found that improvements were distributed into 2 groups and there was the difference between the rate of satisfaction that depended on renewal of the contract intent.
