We have successfully demonstrated the inkjet printing process to fabricate $Al_2O_3$ thick films without a high temperature sintering process. A single solvent system had a coffee ring pattern after printing of $Al_2O_3$ dot, line and area. In order to fabricate the smooth surface of $Al_2O_3$ thick film, we have introduced a co-solvent system which has nano-sized $Al_2O_3$ powders in the mixture of Ethylene glycol monomethyl ester and Di propylene glycol methyl ether. This co-solvent system approached a uniform and dense deposition of $Al_2O_3$ powders on the substrate. The packing density of inkjet-printed $Al_2O_3$ films is more than 70% which is very high compared to the value obtained from the films synthesized by other conventional methods such as casting processes. The characterization of the inkjet-printed $Al_2O_3$ films has been implemented to investigate its thickness and roughness. Also the dielectric loss of the films has been measured to understand the feasibility of its application to 3D integration package substrate.

This study aims to predict uncertain future scenarios that may unfold in South Korea in the near future, utilizing the theory of extreme events(X-events). A group of 32 experts, consisting of government emergency planning officers, was selected as the focus group to achieve this objective. Using the Focus Group Interview (FGI) technique, opinions were gathered from this focus group regarding potential X-events that may occur within the advanced science and technology domains over the next 10 years. The analysis of these opinions revealed that government emergency planning officers regarded the "Obsolescence of current technology and systems," particularly in the context of cyber network paralysis as the most plausible X-event within science and technology. They also put forth challenging and intricate opinions, including the emergence of new weapon systems and ethical concerns associated with artificial intelligence (AI). Given that X-events are more likely to emerge in unanticipated areas rather than those that are widely predicted, the results obtained from this study carry significant importance. However, it's important to note that this study is grounded in a limited group of experts, highlighting the necessity for subsequent research involving a more extensive group of experts. This research seeks to stimulate studies on extreme events at a national level and contribute to the preparation for future X-event predictions and strategies for addressing them.

Stimulation of epidermal growth factor receptor (EGFR) is essential in signaling pathway of tumor cells. Thus, EGFR has intensely studied as an anticancer target. We developed hologram quantitative structure activity relationship (HQSAR) models for data set which consists of tricyclic azepine derivatives showing inhibitory activities for EGFR. The optimal HQSAR model was generated with fragment size of 6 to 7 while differentiating fragments having different atom and connectivity. The model showed cross-validated $q^2$ value of 0.61 and non-cross-validated $r^2$ value of 0.93. When the model was validated with an external set excluding one outlier, it gave predictive $r^2$ value of 0.43. The contribution maps generated from this model were used to interpret the atomic contribution of each atom to the overall inhibition activity. This can be used to find more efficient EGFR inhibitors.

기존 주경로 연구는 과거 핵심기술의 진화를 구조화하는데 적합하나, 패러다임 전환기의 잠재적 후보기술 파악과 주류기술 교체를 예측하기는 어렵다. 본 연구는 링크 중요도, 성장 속도 지표, 핵심 루트 방법을 복합해 특허 인용 네트워크로부터 주경로상의 기술을 대체할 잠재적 후보기술들을 파악하는 방법을 제시한다. 링크 중요도에 기반해 주경로를 도출하고, 성장 속도 지표를 활용해 주경로 대비 고성장하는 잠재적 후보기술 경로들을 도출한다. 성장 속도 지표는 상대적 성장성 평가에 활용되고, 이를 통해 주경로를 교체할 가능성이 높은 잠재적 후보기술을 파악할 수 있다. 차세대 기술 후보들이 다수 등장해 경쟁하고 있는 바이오 연료기술에 적용한 결과 실제 차년도에 주경로상의 기술을 교체하는 후보기술들을 파악할 수 있었다. 기술 패러다임 전환기 후보기술에 대한 정량적 분석을 가능하게 하고, 주경로 기법의 활용범위를 미래기술 예측으로 확대한 측면에서 학문적 의의가 있다. 실무에서는 차세대 후보기술 파악의 정확도 제고에 기여할 수 있다.

The study focused on setting priority among the future core technologies that were derived by Delphi in agricultural management ＆ information using analytic hierarchy process(AHP). Items for setting priority were decided as ‘technology’, ‘market’, and ‘public concerns’by council. The future core technologies were divided into four parts by importance and R＆D level. Technologies which consisted of upper two parts having higher importance were considered in the study. Questionnaires were given to 9 specialists in biosystems engineering. As the results, ‘market’ was decided as a most important item. The most important technologies were ‘Developing technology and system of post harvest processing for higher quality rice’ in group I, and ‘Developing sensor technology to evaluate quality and safety for agricultural products’ in group II.

The effects of addition of $D_2$ to conventional gases on the discharge characteristics were investigated in this work with the aim of improving the voltage margin, the wall charge and the jitter. The addition of an extremely small gas-inlet amounts of $D_2$ increased the number of electrons which improves the $Xe^{\ast}$ density and $Xe_2^{\ast}$ density. As a result, the voltage margin, the jitter and the wall charge increased.

과학기술의 발전으로 세계 각국의 경쟁은 지상을 넘어 우주로 나아가고 있다. 현재 미국을 비롯한 세계 우주기술 선진국들은 달 및 행성탐사 우주선 개발과 같은 유인 우주기술 개발에 박차를 가하고 있다. 따라서 미국, 러시아, 유럽연합(독일, 프랑스 등 11개국), 캐나다, 일본을 중심으로 운영되고 있는 우주정거장은 유인 우주행성탐사 시 생명체 유지에 필요한 시스템 개발과 검증을 위한 기초/응용과학 실험실로 활용되고 있다. 특히 우주환경에서 화재의 발생과 감지/소화의 메카니즘을 이해하고자 다양한 연소실험이 이루어지고 있다. 본 논문에서는 가장 기본적인 우주환경인 미세중력환경에서의 화염의 점화 및 형상특성을 고찰해보고 우주환경 화재안전에 관한 일반적인 내용을 기술하였다.

Korea has pursued economic development based on ICT through R&D policy incorporating CDMA. However, the future society of the Fourth Industrial Revolution is expected to include a new type of industrial development that combines ICT with the non-ICT industry, making it impossible to secure national competitiveness without the source technology of the ICT industry. Therefore, in this thesis, we examine the ICT industry and ICT R&D policy from the point of view of the current ICT as a future source technology source of Korea, and identify strategies to determine ICT as a future technology source through a SWOT analysis.

In the early 20th century, Walter Benjamin analyzed the changes in the value of traditional art forms under the industrial era and the changes in the aesthetic attitude of the masses. A century later, in the contemporary multi-art world, the traditional medium of shelf painting is once again experiencing a similar situation as the last century. Emerging technology display modes such as digital virtual reality and digital immersive experience can achieve digital reproduction of paintings on shelves and reach a certain level of performance, which once again shocks the public's aesthetic perception. This paper attempts to illustrate the outstanding characteristics of the new art form after digital reconstruction by exploring the transformation and sublimation of digital technology to shelf painting. We predict that art research on future reality and augmented reality according to the artificial intelligence era will be conducted in depth in the future.
