  • 무기체계 개발기간을 고려한 신뢰성 성장관리 시험기간을 설정하여 시험 시료 수를 산정하였다. 최적의 신뢰성 성장관리 시험 설계 조건은 신뢰도 80%, 신뢰수준 60%, 시험기간 6개월이었다. 이 때, 고장이 0번 발생하는 경우 시험 시료 수는 4개, 고장이 1번 발생하는 경우 시험 시료 수가 9개가 필요한 것으로 분석되었다. 본 논문에서 제시한 시료 수 결정 방안을 활용하면, 탐색개발 단계에서 체계개발 단계로 전환 시 신뢰성 성장관리 시험 시료 수 예산을 확보하는데 근거로 활용 가능하다.

  • The study examined the characteristics of internet shopping mall sites including on-line market places and integrated internet stores from a perspective of consumer protection. Specifically, the study investigated 1) whether sufficient information is provided on the internet shopping mall sites, 2) whether shopping mall sites abide by internet advertising principles, and 3) specific examples of consumer misleading potentialities from internet shopping sites. Further, on-line market places and integrated internet stores were compared based on their informativeness and potential consumer misleading factors. Total 50 shopping mall sites were analyzed for examining the types of information provided and consumer misleading factors. To verify study questions, descriptive statistics were used. For comparison between on-line market places and integrated internet stores, Chi-square test and independent-sample t-test were employed. The results of this study were as the following: First, not a few of the internet shopping mall sites did not provided important information such as safety and warrantees. Second, important disclosures were not noticeable on the web pages and distracting factors were frequently used. Third, integrated internet stores were desirable compared to on-line marketplaces based on informativeness and consumer misleading potentialities. As the result of this study, internet shopping malls need to advised to provide sufficient information and reduce potential misleading factors.

  • Purpose: The purpose of this study was to identify the degree of critical thinking disposition of nursing students and the factors influencing critical thinking disposition. Method: The subjects were 406 nursing students attending at one university who have been taught by the integrated nursing curriculum. Data was collected by a self-administered questionnaire from Nov. 11, 2007 to Nov. 30, 2007. The survey tool developed by Yoon(2004) was used. Data was analyzed by t-test, one way ANOVA and Scheffe test using SPSS Win 12.0. Result: The mean score of critical thinking disposition was 3.57. The sub scales of critical thinking disposition were statistically significant in regard to grade, age and character of subjects. Overall mean score of critical thinking disposition and its sub scales were statistically significant according to the degree of satisfactory of majoring nursing, reason of choosing nursing as a major and satisfaction on integrated nursing curriculum. Conclusion: Critical thinking ability is very important in various nursing situations. Integrated nursing curriculum was developed to improve critical thinking ability of nursing students. It is recommended that evaluation on the goal attainment of the integrated nursing curriculum needs to be monitored continuously.

  • In this paper, expandable bobbin type multiple integrated coupled-inductor applied 4-paralled switching rectifier was proposed. To design the proposed inductor easily, inductance designing formula was derived through magnetic circuit analysis of the 4-paralleled integrated coupled-inductor. Furthermore, to verify practicality of the proposed inductor, it was applied in 600W class 4-paralleled interleaved switching rectifier, and the steady-state characteristics of the proposed inductor and discrete inductors were compared. Consequently, it was showed that the proposed inductor can replace the conventional discrete inductors with alternative electrical characteristic standard, hence miniaturization of the SMPS can be achieved. From the test result, test circuit with the proposed inductor showed maximum 97.1% of power conversion efficiency and under 18W of power loss where the circuit with discrete inductors showed 96.7% and 20W respectively.

  • This paper develops and builds an Integrated Assessment System for National Competency Standard Professional Basic. The integrated evaluation system for basic job competency in the National Competency Standards is developed to conduct examination by means of computers, smartphones and tablet PCs. The system can be used for the basic job competency test, examination for online cyber universities, job competency examination for enterprises, and the listening, reading, and speaking test in the foreign language proficiency examination and is even better in terms of facility investment and saved operating costs as well as efficient use of spaces in comparison with conventional evaluation schemes. Even greater synergy effects can be achieved by providing support for the integrated evaluation system for basic job competency in connection with the NCS qualification system. The evaluation system has been tested and practiced at a specialized high school and can be applied to the NCS education evaluation of the college and four-year college and to the selection examination of new employees of the company.

  • In recent navigation system, the profitable solution is to integrate the GPS and Stapdwon INS (SDINS) system and its integration allows compensation for shortcomings of each system. This paper describes the hardware preparation and presents the test results obtained from the automobile test of the developed system. The automobile tests was conducted with two kinds of inertial sensors and GPS receivers : short range and middle range test, to verify and evaluate the performance of the integrated navigation system. The reference of position is given by the Differential GPS(DGPS) which has cm-level accuracy to compare the accuracy of system. Kalman filtering is used for integrating GPS and SDINS and this filter effectively allows the long-term stability of GPS to correct and decrease the time deviation error of SDINS.

  • 본 연구는 동작의 기본영역이 강조된 통합적 신체표현활동 프로그램을 개발, 실행하여, 본 프로그램 참여가 유아의 창의성 증진에 미치는 효과를 검증하고자 하였다. 이를 위해 충청북도소재 A 병설유치원의 단일연령으로 구성된 2개의 만4세반을 실험집단과 통제집단으로 각각 선정하였으며, 10주간 30회에 걸쳐 통합적 신체표현활동 프로그램을 실시하였다. 창의성은 프로그램 실시 전후에 Torrance의 'Torrance Test of Creative Thinking(TTCT)'를 김영채(2010)가 한국판으로 표준화한 유아 창의성 검사 중 도형검사 A형을 사용하여 측정하였다. 수집된 자료를 대응표본 t-test를 사용하여 분석한 결과, 실험집단의 경우 프로그램 참여 이후 창의성 총점과 유창성 및 개방성 점수가 유의미하게 증가한 것으로 나타났다. 반면 공분산 분석을 사용하여 분석한 결과, 창의성 하위차원 중 개방성, 제목의 추상성 및 정교성 점수에서만 실험집단과 통제집단 간의 의미 있는 수준의 차이가 나타났다. 결과적으로 통합적 신체표현활동은 유아의 전반적인 창의성 증진에 효과가 있었으나, 창의성 하위차원에 따라 그 영향은 차별화되는 것으로 밝혀졌다.

  • Purpose: The purpose of this study was to test the effectiveness of an eight session integrated case management program for improvement of medication adherence, physical function, pain, and depression among medical aid beneficiaries with osteoarthritis. Method: A nonequivalent control group pre-posttest design was employed. Participants were 55 medical aid beneficiaries who agreed to participate in this study, and were assigned to an experimental group (n=28) or control group (n=27). The framework of this research derived from Cox's Interaction Model of Client Health Behavior guided the overall intervention and the components. The program led by a case manager with a medication calendar, motivating interviewing and coaching strategies and collaboration with a pharmacist. Analysis included change in scores, ${\chi}^2$-test, and t-test. Result: The results showed significant increase in medication adherence, physical function and decrease joint pain, joint stiffness and depression in the experimental group compared to the control group. Conclusion: The eight session integrated case management program indicated an effect on medication adherence, pain, physical function, and depression. Partnership with a pharmacist is recommended for medication adherence and conduct of further studies will be needed in order to determine the long-term effect of an extended integrated program on health outcomes.
