In this study, (3,4-epoxycyclohexane)methyl 3,4-epoxycyclohexylcarboxylate acrylate was synthesized by reacting (3,4-epoxycyclohexane)methyl 3,4-epoxycyclohexylcarboxylate with acrylic acid to minimize hardening shrinkage and to improve heat resistance, which are known as disadvantages of photopolymers for 3D printing application. Urethane acrylate was synthesized by reacting 1,3,5-triazine-2,4,6-triamino alcohol, 2-hexylethyl acrylate, and isophorone diisocyanate in order to improve the mechanical properties without deteriorating the heat resistance. The physical properties before and after the synthesis of the acrylate and the mechanical properties when the urethane acrylate was applied were investigated. The reaction progress of the composite was examined by FTIR and $^{13}C$ NMR. The heat deflection temperature, flexural strength, and surface hardness of the molding were measured. The curing behavior by Photo-DSC ultraviolet irradiation was also examined.

이 논문은 관찰학습에서 나타나고 있는 반두라의 대리강화에 대한 이론과 효과들을 살펴보고, 그 개념을 기독교교육에서 행해지고 있는 영적 롤 모델링 전략에 적용한 연구이다. 이를 위해 먼저 반두라가 소개하고 있는 대리강화란 무엇이며, 관찰학습에서 대리강화가 어떻게 발생하는가 그리고 대리강화가 관찰자의 행동 변화에 어떠한 영향을 미치는가에 대하여 살펴보았다. 특별히 반두라는 관찰학습과 모방 혹은 반모방 행동 안에서 일어나는 학습과정에 대하여 개념화하였다. 이를 바탕으로 하여 반두라는 관찰학습에서 일어나는 대리강화의 과정을 4단계(집중, 기억, 행동재생, 그리고 동기화)로 분류하여 설명한다. 그뿐만이 아니라. 대리강화의 효과에 대해 3가지(관찰학습효과, 억제-탈억제효과, 유발효과)를 제시하였다. 이러한 반두라의 대리강화 이론과 그 효과를 바탕으로 하여 기독교교육에서 논의되고 있는 예수님 닮아가기 혹은 제자훈련 안에서의 영적 롤 모델링 전략을 재평가했다. 특별히 성경에서 사용하고 있는 모방에 대한 개념을 반두라의 대리강화 이론과 비교하면서 재해석하였고, 사도 바울이 제시하고 있는 영적 롤 모델의 역할을 대리강화의 효과라는 차원에서 재점검했다. 그 결과 2가지 차원에서의 영적 롤 모델 전략을 발견하였다. 즉 바울의 영적 롤 모델 역할은 긍정적인 차원에서 대리강화로써 신자로 하여금 기대되는 행동을 실행할 수 있도록 도와주는 하나의 본보기가 된다. 반면에 바울의 명령은 신자들에게 명확한 탈억제 효과를 불러일으키는 부정적인 차원에서의 대리강화로 사용되고 있음을 발견하였다. 그리고 마지막으로 관찰학습에 대한 연구들과 성경적 영적 롤 모델링 전략을 서로 연관시킴으로써 반두라의 대리강화가 기독교교육에 미칠 가능성을 함의하였다. This study reviews Bandura's vicarious reinforcement in observational learning process and implies this concept into Christian education in terms of spiritual role modeling. The first part of this study answers three questions: "what is vicarious reinforcement?" "how does vicarious reinforcement take place in observational learning?" and "how does vicarious reinforcement affect observer's behavior change?" Bandura conceptualizes the learning process with observational learning and imitative or non-imitative performance. Based on this concept, Bandura define the roles of vicarious reinforcement in the four steps of observational learning process: attention, retention, motor reproduction, and motivational process. Also, the three effects of vicarious reinforcements are explained in the following categories: the observational learning effect, inhibitory or disinhibitory effects, and eliciting effect. Adapting the structure of observational learning theory in terms of the effect of vicarious reinforcement and the function of role models, the second part of this study examines the biblical concept of imitation of Christ and the modeling strategy of discipleship. Especially Paul's spiritual role model serves as positive vicarious reinforcement for the Christian believers to perform the desired behaviors. Also, Paul's condemnation serves as explicit negative vicarious reinforcement. Then, the last part of this study covers the implication of these findings from observational learning and empirical studies in terms of spiritual role modeling to Christian education.

Biogenic opal crash at about 6.7 Ma was identified at both IODP Site U1447 and NGHP Site 17 in the Andaman Sea. The different biogenic opal content and general variation pattern between two sites may be attributed to the different concentration of analytical reagent and sedimentation rate estimated by the different chronological approaches. Nevertheless, this study suggests that the biogenic opal crash in the Andaman Sea is closely related to the restriction of Indonesian Throughflow and to the decreasing strength of Indian summer monsoon during the late Miocene, both of which resulted in the reduction of nutrient supply.

Korea has continuously increased investment on R&D to improve global technology competitiveness through technology innovation. Korea's R&D expenditure as a percent of GDP is world's No. 1 as 4.15 and it accomplished 1 trillion won trade volume for 4 consecutive years. However, despite these efforts, technology balance of payment, which is an important factor that can measure nation's technology competitiveness is in a state of chronic deficit and the lowest level among OECD countries. In this paper, we studied methods to improve Korea's technology balance of payment We figured out concept and current state of technology trade and examined the importance of technology trade through making a comparison between commodity trade and technology trade. There have been studies regarding technology trade, but there was no study which tried to figure out cognition on technology trade from the point of view of companies which plays an important role in technology trade. For this, this study distinguished companies with experience in technology trade and which have not and conducted a survey to figure out cognition and current state of companies. The survey result showed noticeable difference on cognition of top decision makers between companies with experience in technology trade and which have not and there are serious shortage in department and staff which is exclusively responsible for technology trade. Also, despite their needs for education regarding technology trade, the ratio of employees who received education is below 10 % of the total respondents. This study suggested improvement methods such as reforming survey methods of technology trade statistics, enhancing social cognition, supporting to vitalize technology export, building infrastructure regarding technology trade, and opening education programs for cultivating experts based on preceding research and industry survey.

Backfire for the spark ignition hydrogen engine was possible to control by retard of the intake valve opening timing(IVO). However, for the HCCI(Homogeneous Charge Compression Ignition) H2 engine, backfire occurred due to the excessive pressure rising by high compression ratio even when same method was used. In this study, in-cylinder pressure and intake pressure were analyzed with the intake valve opening timing and the compression ratio, for grasp of transient process and characteristics of backfire occurred in the HCCI H₂ engine. As the results, it was shown that backfire was occurred always after knock and was not significantly affected by retard of the intake valve opening timing under given experimental conditions. In addition, the higher compression ratio or the more retarding of intake valve opening timing, the more advanced backfire occurrence timing.

IVI system has recently adopted the USB 3.1 Gen1 interface for playing high quality media and high speed data communication. Because data rate of USB3.1 Gen1 interface is up to 5Gbps, when designing a physical layer, SI characteristics should be considered at system level. This paper analyzes and improves the SI characteristic of USB3.1 Gen1 interface with the IVI system to satisfy the USB 3.1 Gen1 Tx compliance test specification required for USB product certification. This paper also proposes a configuration of IVI system for USB certification.

디지털 시대에서 스마트폰과 같은 개인 소형 디바이스의 중요성이 커지고 있다. 개인 소형 디바이스는 생활양식과 정보 접근에 영향을 미치며, 이에 따라 소형 디바이스 중 하나인 스마트폰 재인식 기술은 보안, 개인화 서비스, 사용자 행동 분석 등 다양한 분야에서 중요한 역할을 할 수 있다. 인공지능과 머신러닝의 발전은 이 기술의 정확도와 효율성을 향상하고 있지만, 충분한 데이터셋 부족과 다양한 환경에서의 정확도 유지는 주요 도전 과제다. 본 논문에서는 스마트폰에 초점을 맞춘 새로운 소형 디바이스에 대한 데이터셋(SMPReID-37) 구축 방법에 대해 제안하고 해당 데이터셋을 활용한 재인식 모델을 제안였다.
