A more accurate method of feature point extraction and matching for three-dimensional reconstruction using low-resolution images of crops is proposed herein. This method is important in basic computer vision. In addition to three-dimensional reconstruction from exact matching, map-making and camera location information such as simultaneous localization and mapping can be calculated. The results of this study suggest applicable methods for low-resolution images that produce accurate results. This is expected to contribute to a system that measures crop growth condition.

오늘날 정보통신기술의 발달로 스마트폰을 활용한 스마트러닝의 관심이 높아지고 있다. 하지만 부정적인 시각도 높아 긍정적인 학습효과를 제시하기 위해 많은 연구가 시도되고 있지만 대부분의 기존 연구에서는 이론적인 학습효과만을 제시하고 있어 긍정적인 학습효과를 증명하기에는 많은 부족함이 있다. 따라서 본 연구에서는 뇌파를 이용한 과학적인 근거를 제시하기 위하여 Mindset 장비를 이용하여 학습자의 Attention과 Meditation에 관한 뇌파를 분석하였다. 실험은 스마트폰을 활용한 학습과 기존의 종이를 활용한 학습으로 두 집단 간의 뇌파를 비교 분석 하였다. 실험 결과 스마트폰을 활용한 집단이 기존의 종이를 활용한 집단 보다 Meditation 뇌파가 지속적으로 높게 나타났으며 학습 시간이 지남에 따라 스마트폰을 활용한 집단의 Attention 뇌파가 높게 나타나 스마트폰을 활용한 학습이 학습자를 더욱 집중하게 만든다고 볼 수 있었다.

스마트폰의 잠금을 해제하기 위해 초기에 사용자를 인증하는 과정을 한 번 통과하면 스마트폰의 모든 정보에 접근 가능하다. 현재 스마트폰을 사용하고 있는 사용자가 초기 인증된 사용자인지 아닌지 여부를 판단하지 않기 때문에 인증된 스마트폰에 타인이 접근한다면 모든 정보가 유출될 수 있다. 본 논문에서는 스마트폰 기반 continuous authentication 기술에 대한 연구 동향에 대해 소개하고 현재까지 연구된 기술들을 상용 스마트폰에 적용할 수 없는 한계점에 대해 분석한다.

The study is to investigate research trends and knowledge structures in the Smart Farm field. To achieve the research purpose, keywords and the relationship among keywords were analyzed targeting 104 Korean academic journals related to the Smart Farm in KCI(Korea Citation Index), and topics were analyzed using the LDA Topic Modeling technique. As a result of the analysis, the main keywords in the Korean Smart Farm-related research field were 'environment', 'system', 'use', 'technology', 'cultivation', etc. The results of Degree, Betweenness, and Eigenvector Centrality were presented. There were 7 topics, such as 'Introduction analysis of Smart Farm', 'Eco-friendly Smart Farm and economic efficiency of Smart Farm', 'Smart Farm platform design', 'Smart Farm production optimization', 'Smart Farm ecosystem', 'Smart Farm system implementation', and 'Government policy for Smart Farm' in the results of Topic Modeling. This study will be expected to serve as basic data for policy development necessary to advance Korean Smart Farm research in the future by examining research trends related to Korean Smart Farm.

This study confirms the impact relationship between the president and employee competency related to smart factory construction of manufacturing SMEs, the acceptance intention and management performance in smart factory construction. The 310 data collected through a questionnaire were tested for research hypotheses through SEM. As a result, the president and employee competency affects the smart factory acceptance intention and the employee competency affects the management performance. Acceptance intention has a positive impact on management performance. Regional characteristics have a moderating effect on the relationship between president competency, acceptance intention, and management performance. Through this study, it was confirmed that the president and employee competency was an important factor in smart factory built.

The aim of this study was to determine how to improve smart working in South Korea. Smart working has recently become a key issue in e-government and flexible working studies. Smart working can improve public servants' quality of life and job performance. However, institutional, managerial, and infrastructural conditions that support smart working must be implemented for smart working arrangements to be successful. Therefore, this study analyzed the impact of institutions, management, and infrastructure on the effectiveness of public servants working in smart working conditions. The results showed that institutional, managerial, and infrastructural factors have a significant impact on the effectiveness of civil servants working in smart working conditions. Institutional and infrastructural factors also influenced organizational effectiveness. These findings have implications for how to manage smart working in the public sector in South Korea.
