통계학 입문을 배우는 과정에서 여러 종류의 자료와 분석방법을 접하게 된다. 현재 가장 많이 사용되고 있는 통계 소프트웨어 패키지 가운데 하나인 SAS를 사용해서 실제 입문과정에서 나오는 예제들과 그 예제에 대한 SAS 코드를 제시함으로써 이론과 병행되는 입문 과정의 교육에 도움을 주고자 하며 차후 고급 과정에서 복잡하고 많은 양의 자료를 분석할 때 보다 쉽게 SAS를 활용하는데 편리함을 제공하고자 한다. 먼저 입문과정에서 자료를 정리하는데 사용되며 여러가지 도표를 만들어 내는 PROC CHART, PROC UNIVARIATE의 예제가 소개되고, 여러가지 기술적인 (descriptive) 통계량의 값들을 계산하는 PROC MEANS, PROC SUMMARY, PROC UNIVARIATE의 예제를 제시하며, 상관계수와 공분산을 계산하는 PROC CORR, 모집단의 평균을 검정하는데 사용되는 PROC TTEST, PROC MEANS의 예제를 제시하였다는 PROC CORR, 모집단의 평균을 검정하는데 사용되는 PROC TTEST, PROC MEANS의 예제를 제시하였다.

This study was conducted to analyze new nurse satisfaction and factors of the new nurse orientation program and improve their effectiveness. The CIPP evaluation model was applied in this study to assess each module of the program systematically. The respondents of the survey were 452 of five affiliated hospitals of an educational foundation. The respondents' perceptions were 'Senior', 'Operating', 'Introduction', 'Unity', 'Usefulness', and 'Needs' (from highest to lowest). Multiple regression analysis indicated that 'Operating', 'Unity', 'Usefulness', and 'Hospital Introduction' had a significant impact on satisfaction. The results presented herein indicate that planners and operators should improve effectiveness of new nurse orientation programs by enhancing sense of unity, instilling confidence as a nurse, and increasing personal utilization of subjects.

An 'Introduction to Creative Engineering Design' course at College of Engineering at Chungnam National University is required for all freshmen. The objective of this course is to educate the freshmen with basic engineering design concepts and experiences in creative problem-solving approaches. It provides the students learning opportunities in solving engineering design problems through team efforts and creative approaches. Thus, this course emphasizes creative ideas and thinking, engineering design experiences to students over the course. This study presents the syllabus, the examples of PBL (problem based learning)-related activities as a team, and the results of the course evaluation and outcomes. Based on the results of this study, we can conclude that overall this course using PBL method had significant positive effects on the course outcomes and the creativity of the engineering freshmen in the department of environmental engineering at Chungnam National University. However, there are still efforts to be needed to improve the PBL-related activities in the course, including students' workload, financial supports, and team work.

In this paper, we introduce development process and application of a simple and effective model of a statistics laboratory using open source software R, one of leading language and environment for statistical computing and graphics. This model consists of HTML files, including Sage cells, video lectures and enough internet resources. Users do not have to install statistical softwares to run their code. Clicking 'evaluate' button in the web page displays the result that is calculated through cloud-computing environment. Hence, with any type of mobile equipment and internet, learners can freely practice statistical concepts and theorems via various examples with sample R (or Sage) codes which were given, while instructors can easily design and modify it for his/her lectures, only gathering many existing resources and editing HTML file. This will be a resonable model of laboratory for studying statistics. This model with bunch of provided materials will reduce the time and effort needed for R-beginners to be acquainted with and understand R language and also stimulate beginners' interest in statistics. We introduce this interactive statistical laboratory as an useful model for beginners to learn basic statistical concepts and R.

In this paper the author proposes a case study of a freshmen introduction to engineering design course ing LEGO Mindstorm NXT and analyzes the survey results of the course. The diffilculties are that this course should provide various aspects of design experiences to the students while not requiring the major knowledge and skills and it should attract the students to the engineering major. According to our case study LEGO mindstorm can be a good solution to this problem. The design experience with LEGO Mindstorm NXT provides students with various aspects of design experiences including defining problem, finding constraints and functions, exploring design space, and performing preliminary design, as well as fun. This paper also provides a project list that can be used for freshmen design experience including soccer game robots, line tracer, and vacuum cleaner etc.

본 논문에서는 파이썬 코딩 플랫폼에서의 LLM(Large Language Models)을 로직 및 문법 에러 확인, 디버깅 도구로 활용할 수 있는 시스템을 제안한다. 이 시스템은 사용자가 코딩 플랫폼에서 작성한 파이썬 코드와 함께 발생한 에러 문구 및 프롬프트를 LLM 모델에 입력함으로써 로직(문법) 에러를 식별하고 디버깅에 활용할 수 있다. 특히, 입문자를 고려해 프롬프트를 제한하여 사용의 편의성을 높인다. 이를 통해 파이썬 코딩 교육에서 입문자들의 학습 과정을 원활하게 진행할 수 있으며, 파이썬 코딩에 대한 진입 장벽을 낮출 수 있다.

The occurrence of thrombotic occlusion & endothelial injuries at the site of anastomosis have been considered as major problems in microvascular surgery. The purpose of this study was to ascertain whether a end-in-end(sleeve, telescope) anastomosis compared favorably with end-to-end anastomosis in healing procedures on the endothelium and to study the possibility of clinical application in end-in-end method. The microvascular anastomoses have been performed with end-in-end method in the femoral arteries of 20 rats group, also with end-to-end method on the same arteries of another 20 rats group, and then the four anastomosed vessels in subdivided groups on each group were taken after period of 1, 3, 7, 14, 21 days following by anastomoses for scanning electron microscope observation. The results were as following: 1. The patency rate was 90% in the end-in-end group and 85%in the end-to-end group and late thrombus occurred at 7, 14 days on both groups, which suggested -consistent monitoring of patency was required for two weeks at least. 2. Platelet aggregates at the site of anastomosis began to organize on post-operation 3 days and in the end-in-end group, the initially decreased lumen of inserted vessel was gradually increasing on 7 days due to atrophy of the medial layers. 3. Re-endothelialization was completed between 7 and 14 days in end-in-end group, whereas between 14 and 21 days in end-to-end group.
