This study explores changes of industrial scales and building activities in the semi-industrial area of Seoul's Seong-su, responding to the shifts of industrial structures and policies in the Korean society. The purpose of this study is to investigate patterns of construction activities of factory buildings in the Seong-su semi-industrial area by analyzing changes in industrial facilities. As a result of the analysis, the change of the factory building area come out from the recent survey implies the possibility of entrepreneurial inflow as much and the new constructions and some remodeling cases which are characterized by complexity seem to correspond to the industrial structure. However, it is unreasonable to believe that this phenomenon is a mainstream movement involving small-scale factory buildings and companies. This is because there are aspects that are not included in this movement, such as changing the use of buildings without accompanying physical changes. On the other hand, compared to various movements of individual companies in response to the industrial structure, the physical plan suggests a limited alternative centering on the floor area ratio and the building area ratio. This means that the efforts to attract and grow the power of knowledge based-industry through the designation of the Industrial Development Promotion District in part of the case sites, overlook the natural change through remodeling and reuse of existing buildings. In addition, considering the fact that the production space of industrial use can be greatly influenced by the behavior of users compared to general buildings such as residential and commercial, it is necessary to pay attention to various phenomena occurring in the area more locally than the uniform supply policy. Based on these findings, this study contributes to illuminate the legal system related to building act in the Seong-su semi-industrial area and the potential direction of architectural suggestions in related policies and researches.

The concept of smart city is understood as an indispensable component of urban regeneration projects in small cities in terms of providing a better urban environment and efficient living systems with a limited budget. Recently, the Korean government revised the law that related to the construction of the smart city and started to implement the smart city concept not only to new-large urban development but also to small-existed regeneration projects. However, it is difficult for small and medium-sized cities that are suffering from the insufficient professional workforce; knowledge supports for high-tech and lack of professional networks to proceed smart city planning and project that containing regional characteristics. This paper aims to examine the effective way of urban regeneration for small and medium-sized cities through smart city planning and strategy. As an important case, this paper looks at the 'Smart City Challenge' competition that was hosted by the US Department of Transportation in 2015. It examines the background and operation process of the smart city challenge competition, and then analyses each city's strategy and characteristics of seven finalists. This paper highlights the several key lessons to Korean cities: 1) the importance of national government's support in financial and professional resources; 2) the cooperation with local governments and IT corporations which provides realistic and detailed technical solutions; 3) the holistic and integrated approach to urban regeneration starting from transportation issues; 4) the necessity of the government's clear visions and guidelines toward the smart city.

장현광(張顯光)은 조선시대 자연학자 가운데 대표적인 인물 가운데 한 사람이다. 이 글은 그의 우주론 속에 함축된 상수학적 요소의 의의와 한계를 검토하는 데 목표를 둔다. 역학에서 상과 수는 만물의 분별과 그 상호관계, 그리고 그것들의 시간적 질서를 표현하는 개념 도구이다. 그것들은 음양을 결합함으로써 내부 운동인을 확보하고, 우주 만물에 대한 상수학적 해석과 설명의 틀을 구성하였다. 상수학적 우주론의 핵심적인 주장은 우주가 시 공간적으로 유한하며, 그것과 반대로 리(태극)는 무한하다고 하는 것이다. 리가 시 공간적 무한하다는 것은 도덕원리가 절대적이고 항상적임을 의미한다. 이를 통해 장현광은 자신의 우주론이 주자학의 도덕형이상학과 순조롭게 결합될 수 있도록 하였다. 장현광은 역서(易書)를 자연 이해의 준거 또는 범형(範形)으로 강조하는 경향을 보였다. 이는 불완전하나마 소옹에게서 나타났던 법칙 객관주의를 질곡하고, 그의 법칙 개념으로 하여금 경험이나 지식의 확장과 더불어 스스로를 갱신해 가기 어렵게 만들었다. 이러한 이론적 한계에도 불구하고 그의 상수학적 우주론은 당시 성리학의 자연학적 근거를 마련했다는 점에서 긍정적으로 평가할 수 있다.

최근 인공지능 기술의 비약적인 발전에 따라 전천후 로봇 판매원이 실현될 가능성이 부각 되고 있다. 그러나 소비자가 로봇의 설득 메시지를 어떻게 평가하고 반응하는지를 실증적으로 탐구한 연구는 부족하다. 본 연구는 로봇이 제품을 판매하려는 설득 의도를 현저하게 드러내고 로봇과의 물리적 거리가 가까워질 때 소비자의 로봇에 대한 평가와 로봇이 광고하는 제품에 대한 구매 의도에 어떻게 영향을 미칠지를 탐색했다. 이를 위해 2(로봇의 설득의도: 낮음 vs. 높음) × 2(로봇과의 물리적 거리: 보통 vs. 매우 가까움)의 총 4개 집단 간 요인 설계 실험을 진행하였다. 연구결과, 로봇이 드러내는 설득 의도가 높다고 인식할수록 참가자들은 로봇의 전문성과 신뢰성을 낮게 평가하고 로봇이 광고한 제품인 노트북을 구매할 의도도 낮게 보고하는 것으로 나타났다. 한편 참가자들은 로봇이 자신에게 다가오는 거리의 정도와 상관없이 로봇의 전문성과 신뢰성을 비슷하게 평가했지만, 로봇이 자신의 개인 공간으로 가까이 다가올 때에는 로봇에 대하여 더 부정적으로 평가했고 그 제품을 구매할 의도도 낮게 보고했다.

Disease threatens plant growth and recognizing the type of disease is essential to making a remedy. In recent years, deep learning has witnessed a significant improvement for this task, however, a large volume of labeled images is one of the requirements to get decent performance. But annotated images are difficult and expensive to obtain in the agricultural field. Therefore, designing an efficient and effective strategy is one of the challenges in this area with few labeled data. Transfer learning, assuming taking knowledge from a source domain to a target domain, is borrowed to address this issue and observed comparable results. However, current transfer learning strategies can be regarded as a supervised method as it hypothesizes that there are many labeled images in a source domain. In contrast, unsupervised transfer learning, using only images in a source domain, gives more convenience as collecting images is much easier than annotating. In this paper, we leverage unsupervised transfer learning to perform plant disease recognition, by which we achieve a better performance than supervised transfer learning in many cases. Besides, a vision transformer with a bigger model capacity than convolution is utilized to have a better-pretrained feature space. With the vision transformer-based unsupervised transfer learning, we achieve better results than current works in two datasets. Especially, we obtain 97.3% accuracy with only 30 training images for each class in the Plant Village dataset. We hope that our work can encourage the community to pay attention to vision transformer-based unsupervised transfer learning in the agricultural field when with few labeled images.

The article reports the results of an investigation on the practice of providing digital scholarship services at Vietnam National University Ho Chi Minh City, Vietnam. This study is part of an ongoing research project entitled Developing a digital scholarship service framework for universities at Vietnam National University Ho Chi Minh City. It employed a qualitative research approach through in-depth interviews with 31 individuals who are university managers, library managers, lecturers, and postgraduate and undergraduate students from six member universities and Central Library of Vietnam National University Ho Chi Minh City. Research results show that some digital scholarship services have been provided at Vietnam National University Ho Chi Minh City. However, they have not been yet systematically implemented and have not met users' needs. Lack of needed resources such as space, technology infrastructure, human resources, finance, and stakeholder support are among major challenges in developing digital scholarship services. The management of existing digital scholarship services is fragmented without a clear policy for developing digital scholarship and supporting services. The study contributes to the existing knowledge by adding substantially to current understanding of the practice of providing digital scholarship services in Vietnam's universities in the transition period, from state control to autonomy, which has not been much addressed in previous research. Furthermore, this study can be a useful reference for higher education institutions in developing countries regarding implementation of digital scholarship services.

Purpose: During COVID-19, consumers prefer social distancing or contactless activities for safety, and hygienic condition has become one of the most important factors in evaluating restaurants. Therefore, this study aims to investigate whether offline/online word-of-mouth is affected by restaurant quality. Research design, data and methodology: The data were collected from 480 consumers who had experiences of visiting a restaurant in the past 90 days and analyzed with SPSS 28.0 and SmartPLS 4.0 programs. Results: Physical environment and menu had positively significant effects on brand love, while employee service and hygiene had no significance on brand love. Restaurant environment, menu, and hygiene had negatively significant effects on brand hate, but employee service had not significant impact on brand hate. Brand love had positively significant effects on offline and online word-of-mouth, and brand hate had negatively significant effects on offline and online word-of-mouth. Conclusions: First, restaurants need to develop a pleasant space where customers can have emotional experiences. Second, restaurants need to fulfill customers' desire for global food consumption. Third, restaurants should ensure hygiene and safety to prevent customers' brand hate. Lastly, restaurants need to establish offline/online word-of-mouth strategy to identify which restaurant quality attributes influence brand love/hate and offline/online word-of-mouth.

Since the concept of Manned-UnManned Teaming(MUM-T) and Unmanned Aircraft System(UAS) can efficiently respond to rapidly changing battle space, many studies are being conducted as key components of the mosaic warfare environment. In this paper, we propose a rule-based AI engagement model based on Basic Fighter Maneuver(BFM) capable of Within-Visual-Range(WVR) air-to-air combat and a simulation environment in which human pilots can participate. In order to develop a rule-based AI engagement model that can pilot a fighter with a 6-DOF dynamics model, tactical manuals and human pilot experience were configured as knowledge specifications and modeled as a behavior tree structure. Based on this, we improved the shortcomings of existing air combat models. The proposed model not only showed a 100 % winning rate in engagement with human pilots, but also visualized decision-making processes such as tactical situations and maneuvering behaviors in real time. We expect that the results of this research will serve as a basis for development of various AI-based engagement models and simulators for human pilot training and embedded software test platform for fighter.
