Satellite imaging is an effective supplementary data source for detecting and verifying nuclear activity. It is also highly beneficial in regions with limited access and information, such as nuclear installations. Time series analysis, in particular, can identify the process of preparing for the conduction of a nuclear experiment, such as relocating equipment or changing facilities. Differences in the semantic segmentation findings of time series photos were employed in this work to detect changes in meaningful items connected to nuclear activity. Building, road, and small object datasets made of KOMPSAT 3/3A photos given by AIHub were used to train deep learning models such as U-Net, PSPNet, and Attention U-Net. To pick relevant models for targets, many model parameters were adjusted. The final change detection was carried out by including object information into the first change detection, which was obtained as the difference in semantic segmentation findings. The experiment findings demonstrated that the suggested approach could effectively identify altered pixels. Although the suggested approach is dependent on the accuracy of semantic segmentation findings, it is envisaged that as the dataset for the region of interest grows in the future, so will the relevant scope of the proposed method.

본 연구에서는 인간언어공학에서의 활용을 위해 세종전자사전의 의미부류와 KorLexNoun 1.5의 상위노드 간의 사상을 목표로 전문가의 수작업에 의한 세밀한 사상 방법론(fine-grained mapping method)을 제안한다. 또한 이질적인 두 이종 자원 간의 사상에 있어 각 의미체계의 이질성으로 인해 발생하는 여러 가지 문제점을 살펴보고, 그 해결방안을 제안한다. 본 연구는 세종의미부류체계가 밝히고자 했던 한국어의 의미구조와, Prinston WordNet을 참조로 하여 KorLexNoun에 여전히 영향을 미치고 있는 영어 의미구조를 비교함으로써 공통점과 차이점을 파악할 수 있고, 이를 바탕으로 언어 독립적인 개념체계를 구축하는 데 기여할 수 있다. 또한 향후 KorLex의 용언에 기술되어 있는 문형정보와 세종 전자사전의 용언의 격틀 정보를 통합 구축하여 구문분석에서 이용할 때, 세종 의미부류와 KorLexNoun의 상위노드를 통합 구축함으로써 논항의 일반화된 선택제약규칙의 기술에서 이용될 수 있다. 본 연구에서 제안된 사상방법론은 향후 이종 자원의 자동 사상 연구에서도 크게 기여할 것이다. 아울러 두 이종 자원의 사상을 통해 두 의미체계가 지닌 장점을 극대화하고, 동시에 단점을 상호 보완하여 보다 완전한 언어자원으로써 구문분석이나 의미분석에서 이용될 수 있다.

This research has studied the building awareness of Nu-Jeong that a view of nature and aesthetic consciousness to unite the nature are inherent by considering Nu-Jeong of scholars who left fame and wealth behind and retired to hermitage in the backwoods in the 16~18 Century. This is to clarify correlation with leaving nature as it is, namely, an ideal state that scholars at the time would enjoy, through landscape awareness accepted into Nu-Jeong literature. In addition, this research has tracked the ideologic flow that acts on space formation by clarifying Korean unique meanings inherent to Nu-Jeong's cultural landscape. As a suggestion for this, the interpretation through 'Pungsu location Nu-Jeong name's analysis Nu-Jeong literature analysis', etc. was tried, so its integrated conclusion is as follows. It is not a chance that scholars of Joseon have left numerous literature works singing the nature. They already had huge interest and knowledge on the nature, and achieved active poetic exchange by sublimating the praise of nature as literature. Nu-Jeong, which was a place of exchange like this, had cleanliness of the nature and ideological purity as an oppositional space on turbid political realities. The Nu-Jeong literature drew the nature into a literature space as it is, without doing abstraction or ideation on the nature. The owner of Nu-Jeong exclusively possessed such natural landscape in grim and independent postures, so it provided a clue of Nu-Jeong cultural landscape that this research aimed to discuss. Scholars who aimed to raise wide and large vigor filled in between the sky and earth got to convince that people are born from the nature, grow in the nature and finally return to the nature. What people are born from the nature and finally return to the nature is just consistent with Taoistic and Zhua-ngzi thoughts denying human work, and leaving nature as it is or nature itself remained intact which is an ideal state. The construction at the time is a vessel containing the spirit of the times of the era. This thesis has proved that the Nu-Jeong culture of scholars located on the central line of Korean landscape was the flower of Joseon's scholar culture by interpreting it semantically.

This study is about the Data which is one of Euclid's writing. It dealt with the organization of contents, formal system and mathematical meaning. First, we investigated the organization of contents of the Data. Second, on the basis of this investigation, we analyzed the formal system of the Data. It contains the analysis of described method of definition, proposition, proof and the meaning of 'given'. Third, we explored the mathematical meaning of the Data which can be classified as algebraic point of view, geometric point of view and the opposite point of view to 'The Elements'.

The work of design needs not only a lot of scientific information, but also a artistic sensitivity. Designers require abundant imagination to translate the information of the design, into the Gestaltung. Particularly, the translation of ergonomic information into the elements and grammar of the Gestaltung needs an interface. In order to consider the theoretical possibility for this, a view of fundamental notions, the function of design semantics and ergonomic problems in the design process were analyzed. The purpose of this study is the exploration and relevance of the theoretical model for human factors and design semantics, to see if they could be harmonized as a system of a new design method.

In this paper, I raise an objection to "sensitivism" about "know", according to which knowledge ascription is sensitive to contexts of utterance or subjects. While Peter Unger once proposed insensitivism about "know" in terms of insensitivism with respect to absolute terms, David Lewis provided sensitivism about "know" in terms of sensitivism with respect to absolute terms, on the common ground that "know" belongs to a class of absolute terms. On the one hand, I object to Unger-style insensitivism about 'know,' for, I claim, we have reason to opt for sensitivism rather than insensitivism with respect to absolute terms in virtue of the maxim that I call "semantic razor." On the other hand, I also object to sensitivist approaches to "know," for, on reflection, there is such a deep difference between "know" and absolute terms (or, sensitive terms altogether) that "know" cannot be taken to sensitive to contexts as opposed to absolute terms (or, sensitive terms altogether). These claims jointly indicate that "know" should be thought of as an insensitive term even though sensitivism has enjoyed wide acceptance in many other cases.

본 논문에서는 고대 양생사상을 대표하는 "도덕경"과 한의학 양생사상을 대표하는 "황제내경소문 상고천진론"을 중심으로 양생의 의의, 양생의 목표, 방법, 기본사유 등 몇 가지 방면에서 두 경전의 내용을 비교하여 다음과 같은 공통점이 있음을 알 수 있었다. 첫째, 양생은 섭생과 동일한 의미로 천지자연의 이치에 따라 인제 생명을 건강하게 유지하여 장수할 수 있도록 하는 일체의 활동을 의미한다. 둘째, "상고천진론"과 "도덕경"이 모두 육체적 정신적으로 안정상태를 유지하여 질병이 없이 오래 사는 것을 양생의 목표로 삼고 있다. 셋째, 양생의 방법은 두 방면으로 요약할 수 있다. 첫째, 염담무욕(恬淡无欲)을 양생의 핵심요소로 삼았다. 이를 실천하기 위한 구체적 방법으로 노자는 '색(啬)'과 '반박(返朴)'을 제시하였고, 이러한 관념은 "상고천진론"에도 똑같이 보인다. 둘째, 근본 이치인 도(道)에 합치하는 것을 무병장수의 요건으로 삼았으며 구체적인 방법으로 천지자연의 사시음양(四時阴阳)의 규율을 따를 것을 강조하였다. 이는 천인상응사상(天人相应思想)과도 상통한다.
