창의 융합형 인재 양성을 위해 교육현장에서 다양한 테크놀러지를 활용한 교육이 강조되고 있다. 특히 새로 도입된 3D 프린팅 기술은 학생들이 더 진보된 과학적 개념을 배울 수 있도록 하는 큰 잠재력을 가지고 있다. 이에 본 연구에서는 학생 그룹과 성인 그룹으로 나누어 "3D 프린트의 의미와 활용 방안 그리고 캐디안을 이용한 간단한 모형설계 및 제작 수업"을 2차시 분량으로 분배하여 수업을 진행하고, 3D 프린터를 학습에 활용하기에 적절한 연령과 연령별 특성을 알아보고자 세부 항목을 과제 가치(Task Value), 자기효능감(Self-Efficacy for Learning and Performance), 테크놀러지 불안(Technology Anxiety), 수업 만족감(Satisfaction of Class)으로 한정하여 설문을 실시하고 분석하였다. 연구 결과 학생 그룹이 성인 그룹보다 더 높은 과제가치, 자기효능감, 그리고 수업에 대한 만족도를 보이면서, 성인 그룹보다는 학생 그룹에서 3D 프린터 교육의 효율성이 더 높다는 것을 알 수 있다. 두 그룹 모두 과제가치와 자기효능감이 학습만족도와 정적 상관관계가 있는 것으로 나타났다. 또한 성인 그룹의 경우, 테크놀러지 불안이 수업만족도와 부적 관계가 있는 것으로 나타나, 성인학습자를 대상으로 하는 3D 프린터 수업에서는 테크놀러지 불안에 대한 교수 학습지원이 중요함을 알 수 있었다. 향후 3D 프린터가 더 보편화되고 3D 프린터를 활용한 수업이 늘어나 더 다양한 데이터 수집이 가능하게 되면, 보다 세부적인 학습자의 연령별 학습 특성도 비교 분석할 수 있을 것이다. 또한 최근까지의 선행 연구를 분석한 결과 3D 프린터를 이용하는, 학교 현장에서 활용 가능하고 실천적인 혁신 교육 방법에 대한 연구가 다양하게 이루어질 필요가 있음을 본 연구 과정에서 확인할 수 있었다.

Interviews with 17 Korean American professionals living in Korea revealed the relationship between their status, cultural identities, social capital, and conflicts that arise between their understanding of American and Korean social norms. The findings indicate that social capital for Korean Americans in Korea largely comprises of their English community in Korea and the Seoul Global Center; and that their access to social capital in the Korean society, in general, is limited. As result of limited availability and accessibility of social capital, with a sense of superiority, they maintained their American identity. In terms of social control, their lack of motivation to adopt and follow Korean social norms, as well as them being from the U.S., limited changes occurred in their cultural identity. Extending previous research on the Theory of Intercultural Public Relations, the public's power allows them to maintain their cultural identity, which in turn, effect their communication process. Implications of these findings, as well as suggestions for future study, are discussed.

Purpose: The purpose of this study was to develop a website-based patient safety culture promotion program that could be implemented by nurses in real work scenarios. Methods: This study was a methodological study. A patient safety culture promotion program, called 'Safe Culture, Save Patients' was developed, based on structuration theory and performance engineering approaches. Results: This program was delivered in the form of a website containing contents about changes in the work environment, information about accidents and the improvement process details, as well as a program for motivation. The program was tested about the validity on contents and usability - a panel of 14 experts confirmed its validity using the contents validity index (CVI), with a resulting S-CVI of .980. Usability was evaluated by 11 nurses, which allowed finalize the program. Conclusion: The 'Safe Culture, Save Patients' program was a valid program that could be applied in clinical practice immediately. The results of this study warrant further studies to evaluate the effects of this patient safety culture promotion program.

The motivation of this work is to use SAM(Self-Assembled Monolayer) for developing a rapid and flexible non-photolithographic nano-structure fabrication technique which can be utilized in micro-machining of metals as well as silicon-based materials. The fabrication technique implemented in this work consists of a two-step process, namely, mechanical scribing followed by chemical etching. From the experimental results, it was found that thiol on copper surface could be removed even under a few nN normal load. The nano-tribological characteristics of thiol-SAM on various metals were largely dependent on the native oxide layer of metals. Based on these findings, nano-patterns with sub-micrometer width and depth on metal surfaces such as Cu, Au and Ag could be obtained using a diamond-coated tip.

It has been suggested that the motivation for automation of welding processes ncludes the replacement and extension of the functions of human operators. Among these types of the welding automation, SAW(Submerged Arc Welding) was prevalently used, because it is highly suited to a wide range of application, especially for the high speed welding. A Significant portion of the total manufacturing time for a pipe fabrication process is spent on the welding following primary machining and fit-up processes. To achieve the reliable weld bead appearance, the automatic seam tracking and adaptive control to fill the groove are urgently needed. This paper proposed the mechanical functions of multi-torches welding system, flux supply and recovery system in conjunction with the complex air pulsing method and various types of methodologies. It was shown that the multi-torches welding system revealed the high welding qualities for the circular and rectangular pipes. In conclusion, the multi-torches welding system developed will contribute the advanced welding technology, welding automation and increment of the market in these areas.

Since the first oil embargo (1973), there have been developed many different types of energy-economy interaction models based upon various aspects of energy impact mechanism. We will propose to develop an integrated energy-economy interaction analysis system for less developed countries' energy policy analysis, especially for investment analysis toward constructing energy-saving industry infrastructure ; which is based on the motivation of combined energy models by John P. Weyant. This modeling system can cover the economic growth, inter-industry transactions including production features, and process analysis of energy sector in the total network scheme of general equilibrium, so that it can give many political implications as well as the modeling concept to be used for analyzing various political issues and making decisions related to national energy environment.

This study investigates a buyer-supplier supply chain, in which a buyer delegates the production process to a supplier as in many practices. The consumer's buying intention and overall supply chain performance are affected not only by the buyer's decision on sales price but also by the supplier's decision on product quality. Therefore, the buyer has a motivation to control the supplier's quality investment. Among various incentive schemes that the buyer can adopt in practice, we consider a revenue-sharing contract and investigate its unique characteristics. By comparison with a typical wholesale price contract, we reveal that the revenue-sharing contract can enhance supply chain's overall performance, including quality, demand, and profits of not only overall supply chain but also each player. We contribute to the academia and the supply chain practice by providing important guidelines in adopting incentive schemes and effectively managing product quality in a supply chain.

The function is a basic and key concept to understand mathematical problems. However, many students have difficulties to expand the knowledge to other related concepts and to transfer the knowledge to real world problems. The reasons for the problem may be that the concept of function is taught by simplified and abstracted formula without fully understanding of the reasoning process. Also, the examples for the concepts are artificial and not related to students' experiences. Situated learning theory provides great implications to solve these problems. So, this study was designed to teach the concept of function more meaningful to students by appling situated learning theory. Thirty-eight middle school students were participated in this study. Students were provided the instruction designed according to the principles of situated learning theory. Then, they were asked to complete attitude survey questionnair and a performance assessment task. The result showed that the instruction based on situated learning theory was useful to Promote students' understanding and motivation for learning. More implications of the study was provided in the paper.

With the rapid development of digital media, there has been a huge change in a way of communication, a process of information diffusion and a role of traditional media. Not like mass media, social media enables users to generate and tap into the opinions of a larger world. From that reason, social media is impacting marketing strategies. However, still social media marketing researches just focus on case study, analysis of users motivation or analysis of power user's usage pattern. Word-of-mouth has always been important especially in marketing area. In social media, word-of-mouth depends on each user that's why this research focuses on individual user's activity in SNS. I defined 4 factors (produce, diffusion, network size, activity of network size enlarge) that are effect on activity and verified hypothesis by multiple regression analysis, hierarchical regression analysis and moderated multiple regression.
