Many e-learning systems adopts SCORM as an e-learning standard. E-learning systems evaluate and apply the learning difficulty in order to improve the studying efficiency. But, it is hard to change the learning difficulty and provide the customized learning contents during studying in SCORM. Because it is difficult to provide the customized contents to learners by changing the learners' level at runtime and to control optional learning. In this paper, we designed and implemented SCORM-based Contents Organization System on learners' level(SCOS) for complementing the SCORM's weakness. SCOS re-evaluates a learner's level whenever the learner's level is changed during learning, and provides customized contents on the learner's level.

This study examined the factors affecting the emergency nursing performance of nursing students during a simulation. The variables related to the simulation were the objective and subjective emergency nursing performance, critical thinking, program outcome, simulation satisfaction, simulation confidence, and simulation immersion. The participants were 92 senior students who provided informed consent with an explanation about attending the study. The general characteristics and simulation-related data were obtained from the students before and after the simulation. An assessor evaluated the objective emergency nursing performance during the simulation and program outcome through a report reviewed after the simulation. Data analysis was performed using the number, percentage, mean, standard deviation, X²-test, one-way ANOVA, Pearson correlation, and progressive regression through the SPSS/WIN 22.0 program. Emergency nursing performance by the assessor was negatively associated with the satisfaction of clinical practice (r=-.31, p=.005) and positively related to the subjective clinical performance (r=.23, p=.036). The affecting rate was just 12%, which was low for explaining the objective emergency nursing performance during the simulation. Further studies will be needed to explore other factors affecting the emergency nursing performance.

The relocation policy of public Institutions throughout provincial areas that implemented for the purpose of "balanced national development" finished in 2019 with the last relocation of the Korea Institute of Science & Technology Evaluation and Planning, which moved to Chungbuk Innovation City. Electric power public corporations also completed relocation program over eight regions across the nation. This study was conducted empirically to identify the structural relationship between the public service motivation and job attitude. In this, the relationship of organizational change, particularly occurred by the regional relocation, with the psychological state of these organization members (experienced direct changes and got substantial impacts in various aspects such as psychological, economic and living environment, etc.,) was studied. This study aims to seek early organizational stabilization ideas for electric power public corporations after relocation, and to present some implications that can contribute to the secondary relocation of public institutions to local areas. This study shows the statistically significant relationship between the psychological state occurred by relocation and organizational commitment. The result shows that the higher the expectation levels, the higher the degree of organizational commitment, while anxious psychological state has no relation with that. Additionally, expectation level has no significant functional relation with turnover intention. Followings are the major conclusions revealed in this study; The stronger the anxious psychological state, the higher the turnover inducement goes up. The higher the expectation levels, the higher the public service motivation grows, and the higher the anxiety psychological state, the public service motivation lowers. The organizational commitment grows according to the public service motivation proportionally, but the turnover inducement intention is weak. The moderating effect of public service motivation between the expectation of organizational change and turnover intention was not significant, but it was analyzed that the moderating effect of public service motivation formed a significant relationship with other anxiety psychology. The expectation levels of employees of electric power public corporations has grown up after moving to provincial areas. Relationship between the expectation mind and the turnover inducement has decreased after local relocation.

This study aimed to evaluate the relative status using Analytic Hierarchy Process(AHP) on the spiritual factors of the security martial arts for the guards to perform the best security service. There were 540 participants who were students majored in security martial arts, workers for security and specialists of practical and theoretical security martial arts for this study. The exploratory and confirmatory factor analysis were carried out using the selecting data through literature reviews in the level of the factor-extraction about the spiritual characteristics. The specialists' survey was conducted on the relative status among factors using the spiritual concept structure based on the studied above. Selected data was calculated with SPSS 18.0 for windows, AMOS 5.0, and Expert Choice 2000 software. The conclusion can be made through those process above. First, 4 general factors and 20 detailed factors were found as the result of the factor exploration related to the spiritual characteristics of the security martial arts. The result which was verified on Construction validity of searched factors had stable figures on every standard. In other words, the participants for survey on this study "Spiritual characteristic concepts of the security martial arts" can be evaluated it is valid. The general factors of security martial arts' spirit were conceptualized with Psychological spirit, ethical spirit, martial art spirit, practical spirit through the naming process on the general factors of the security martial arts' spiritual characteristic concepts. The detailed factors of security martial arts' spirit were concentration, self-confidence, self-management, immersion, self-esteem in psychological spirit and sacrifice, justice, royalty, peace, sense of duty in ethical spirit and courtesy, toughness, defense, balance of mind and body, bravery in martial arts and responsibility, cooperation, modesty, determination, professionalism in practical spirit of security martial arts. That is, the conceptualization of security martial arts' spirit was verified that it had validity. Second, the hierarchical model of the security martial arts was composed with 4 superordinate concepts and 20 subordinate concepts. As the result of evaluating relative status based on Spiritual characteristics-hierarchy model, the impotance was proven in order of ethical spirit(.482), martial art spirit(.248), practical spirit(.188), psychological spirit(.083). Also the importance related to spiritual characteristics of security martial arts on subordinate concepts was proven in order of sacrifice(.252), courtesy(.110), sense of duty(.108), responsibility(. 073), royalty(.053), toughness(.052), justice(.049), defense(.038), professionalism(.038), determination(.035), cooperation(.029), self-confidence (.026), bravery(.025), self-esteem(.024), balance of mind and body(.023), peace(.019), concentration(.014), modesty(.013), self-management(.011), flow (.007). To sum up, the spiritual factor related to ethics such as sacrifice, justice, royalty, peace, sense of duty was the most important for the security martial arts.

Robot assisted programming education has been highlighted because it enhances the involvement of students. Robots are combined with mechanical and program elements. However, in after school Robotics classes, almost all is education for the mechanical elements of robots. On the other hand, education for robot programming is a starting stage. It is difficult for students to programming with sensors. Therefore, in this paper, I researched the relationships between elements from sensors to output devices. And I applied it to Robotics education. As a result, the students can understand robot because they studied the relationships between data from sensors and output devices. We proved it by the survey after the relationship education.

사이버 공간이 현실 생활의 일부분으로 통합되어가고 사이버 공간에서의 대인간 의사소통이 보편적인 현상으로 나타남에 따라 사이버 공간에서의 의사소통과 경험 그리고 그것의 영향력에 대한 논의는 그 동안 많이 있어왔다. 그러나 기존의 연구들은 사용자의 행동 특성에 따라 사이버 공간에서의 활동과 영향력, 그리고 그 의미가 달라진다는 점을 간과하였다. 따라서 본 연구에서는 동일한 커뮤니케이션 공간인 싸이월드도 그것에 부여하는 가치와 의미는 사람마다 다르고 따라서 행동도 다를 것이라는 가정하에, 싸이월드에서 나타나는 다양한 이용행동과 활동들을 유형으로 분류하고 그 유형에 따라 싸이월드에서의 의사소통 패턴과 경험, 활동에서의 차이를 살펴보고자 했다. 사전 연구로 진행되었던 사용자 인터뷰를 통해 정리된 행동문항을 전체 설문을 통해 분석한 결과 싸이월드에서 보이는 개인의 행동적 특성을 의미하는 5 개 요인(적극성.몰입, 낯선 사람과의 연결과 정보 추구, 사생활 보호, 단순한 연락 수단, 폐쇄성)이 확인되었고, 이렇게 추출된 행동 요인을 토대로 싸이월드에서 나타나는 3 개의 행동 유형(적극적 활용형, 폐쇄적. 다이어리 추구형, 새로운 관계.정보 추구형)이 구분되었다. 행동 요인의 차이로 표현되는 3 개의 행동 유형에 따른 싸이월드에서의 의사소통 패턴과 싸이월드에서의 활동 그리고 싸이월드 경험에 대한 평가를 분석한 결과 행동 유형간에 유의미한 차이가 있는 것으로 나타났다. 본 연구는 동일한 싸이월드라는 공간이 사용자가 추구하는 가치와 목적에 따라 각기 다른 공간으로 기능하고 있음을 보여주었다는 데에 의의가 있으며, 가치의 차이로 나타나는 행동 유형에 따라 싸이월드에서 소통하는 대상과 방식이 달라지고 경험의 의미 또한 달라질 수 있음을 시사하고 있다.

The purpose of this study is to analyze the effects of the introduction of 'business performance evaluation program' on the changes in organizational culture and employee commitment. The data for this study were collected three times, in 2006, 2008, and 2009 from the employees at a public hospital in Korea. The main findings of this study are as follows. 1. Organizational culture has gradually changed as the 'business performance evaluation program' was introduced and implemented. Regarding the changes in the different type of culture, we can see that group culture, developmental culture and rational culture has been stronger and, on the other hand, the introduction of 'the program' did not have as much impact on the hierarchical culture as on the other types of culture. 2. The group culture has have more impact on the organizational commitment than other types of culture. In case of the hierarchical culture, however, statistically significant relationships could not be found between the organizational commitment and the introduction of business performance evaluation program.
