본 연구에서는 산학 연구로 제작된 게임 에디터를 (Game Editor, MakersLab)을 활용하여 실제 게임을 제작하는 학습을 통해 소프트웨어 교육에서의 학습 플랫폼의 중요도와 이에 따른 학습자들의 프로그래밍, 게임의 플레이 및 제작에 대한 인식 변화를 연구하고자 한다. 게임 플레이에는 익숙하지만 프로그래밍과 게임제작에는 경험이 없는 학습자들을 대상으로 게임 에디터를 학습 플렛폼으로 활용하여 프로그래밍 교육 및 게임제작 관련 수업을 진행 후, 학습자들을 대상으로 인터뷰 및 설문조사를 실시하였다. 학습자들은 대부분 항목에서 '만족한다'는 의견이 지배적이었고, 게임이 제작되어지는 과정에 대해 체험한 것에 대해 흥미로웠다는 의견을 주었다. 하지만, 게임 제작을 처음 경험하는 학습자들에게 게임 에디터 플랫폼은 복잡한 인터페이스 및 기능으로 인해 조작의 어려움을 호소하기도 하였다. 게임 플레이 후, 직접 게임을 기획과 제작을 수행하고, 타 학습자와 서로의 게임에 대해 논의하는 과정 등은 어렵다고만 생각되는 소프트웨어 교육의 동기 부여와 흥미 유발을 위한 좋은 학습 재료로 활용될 수 있음을 본 연구에서는 확인 하였다.

The purpose of this study is to evaluate the application of a web-based cost management competency enhancement program (Web-CMCEP) on nursing students. Medical services are limited and essential for maintenance of human basic life. In order to improve the quality of human life, cost management competency that enable efficient allocation of medical resources are essential. This study adopts a randomized controlled pre/post repeated measure design. The sample comprised 39 nursing students in the web-group and 35 in the textbook-group. Experimental group and control group learned respectively with Web- CMCEP and textbook for 4 weeks. The research variables were measured at 4 times: pre, post, after 4 weeks of intervention, and after 8 weeks of intervention. Data were analyzed using χ2 -test, t-test, paired t-test, repeated measures ANOVA, Friedman test, and Wilcoxon signed rank test. Significant differences were found in cost management knowledge. The web-group showed higher cost management knowledge than the text-group. At different measuring points, the Web-CMCEP led to significant increases in the following: cost management knowledge, cost management attitude, cost management behavior, cost management self-efficacy, and entrepreneurship. Based on the findings, we suggested utilizing the Web-CMCEP as a prototype in developing education programs to improve nursing students’ cost management competency and to support nursing start-ups.

Royal jelly (RJ) is a gelatinous substance that bees produce to feed bees and queen bees. It’s frequently sold as a dietary supplement to treat a variety of physical ailments and chronic diseases. While it has long been used in traditional medicine, its applications in Western medicine remain controversial. The inhibitory effect of royal jelly on osteoarthritis was investigated in primary cultured rat cartilage cells and monosodium-iodoacetate (MIA)-induced arthritis rat model 10-hydroxy-2-decenoic acid (10-HAD) is the main fatty acid present in RJ. Among the criteria for RJ quality analysis, 10-HAD content has been proposed as a freshness parameter. We investigated the effect of RJ on the improvement of osteoarthritis on SD rats and they were divided into five groups. In this study, we examined the effect of enzymatic royal jelly (ERJ) administration on osteoarthritis. To determine the antiinflammatory effects of RJ, tumor necrosis factor alpha (TNF-α) and Interleukin-6 (IL-6) expression were measured after lipopolysaccharide (LPS) activation in RAW 264.7 cells. In in vivo animal study, osteoarthritis was induced by intra-articular injection of MIA into knee joints of rats. As a results, ERJ showed that TNF-α and IL-6 levels were decreased by ERJ treatment in a dosedependent manner. In conclusion, ERJ extract was able to inhibit articular cartilage degeneration by preventing extracellular matrix degradation and cartilage cell damage. It was considered that ERJ extract may be a potential therapeutic treatment for degenerative osteoarthritis.

After the permanent shutdown of K1 in 2017, decommissioning processes have attracted great attention. According to the current decommissioning roadmap, the dismantling of the activated components of K1 may start in 2026, following the removal of its spent fuel. Since the reactor vessel (RV) and reactor vessel internal (RVI) of K1 contain massive components and are relatively highly activated, their decommissioning process should be conducted carefully in terms of radiological and industrial safety. For achieving maximum efficiency of nuclear waste management processes for K1, we present activation analysis of the segmentation process and waste classification of the RV and RVI components of K1. For RVI, the active fuel regions and some parts of the upper and lower active regions are classified as intermediate-level waste (ILW), while other components are classified as low-level waste (LLW). Due to the RVI’s complex structure and high activation, we suggest various underwater segmentation techniques which are expected to reduce radiation exposure and generate approximately nine ILW and nineteen very low level waste (VLLW)/LLW packages. For RV, the active fuel region and other components are classified as LLW, VLLW, and clearance waste (CW). In this case, we suggest in-situ remote segmentation in air, which is expected to generate approximately forty-two VLLW/LLW packages.

최근 선진국을 중심으로 소프트웨어(SW) 교육의 중요성에 대한 연구는 계속 쏟아져 나오고 있다. 단순히 프로그래밍 언어를 습득한다는 개념을 넘어서서 논리적 사고력, 문제 해결력 등의 향상을 목적으로 한 SW 교육은 SW 교육 플랫폼을 중심으로 다양하게 개발, 연구되어 지고 있다. 본 연구에서는 컴퓨터를 활용한 SW 학습 플랫폼을 SW 교육을 처음 접하는 학습자들에게 적용하여 SW 교육 플랫폼의 중요성과 효과적인 SW 교육 플랫폼의 요소에 대해 고찰하고 학생들의 동기부여와 참여도를 높이기 위해 게임화 된 학습의 필요성에 대해 논하고자 한다.
