According to the Gyeonggi Provincial Office of Education's 2018 Education Statistics, there are 4,692 schools in Korea, and most of them were built before 1985 and the aging of facilities due to earthquake and external environment has reached a serious point and are vulnerable to safety. The Gyeonggi Provincial Office of Education designated 2,561 buildings with floor space of 1,000 square meters or more under the "Special Act on Safety and Maintenance of Facilities (2018.1.18. Full Revision)" and conducted regular safety inspections. The purpose of this study is to analyze the evaluation of school facilities according to the results of a regular safety inspection and to propose a maintenance plan for educational facilities for future defects according to the conditions of the facilities.

Emotional semantics are the highest level of semantics that can be extracted from an image. Constructing a system that can automatically recognize the emotional semantics from images will be significant for marketing, smart healthcare, and deep human-computer interaction. To understand the direction of image emotion recognition as well as the general research methods, we summarize the current development trends and shed light on potential future research. The primary contributions of this paper are as follows. We investigate the color, texture, shape and contour features used for emotional semantics extraction. We establish two models that map images into emotional space and introduce in detail the various processes in the image emotional semantic recognition framework. We also discuss important datasets and useful applications in the field such as garment image and image retrieval. We conclude with a brief discussion about future research trends.

Recent paradigm in technology shifts from object-based technology to environment-based technology. Issue here is interaction among human, machines, and environment. This requires new interpretations for the space among them. Holistic interactions based on “Mom (embodiment)” suggest a good starting point for this endeavor. The past, present, future of technology are presented in terms of technology’s fundamental virtue: “humanizing technology” or “technology serving human.” Interactive technology initiative (ITI) is an interdisciplinary research group to search for the proper technology and the proper way of implementing technology: “interactive technology” or “soft engineering.” Some experimental activities conducted by ITI are presented in this organized session, “Interactive Technology.” Metatechnology, soft engineering, “Mom (embodiment),” holistic interactions, tangible space, and ubiquitous computing are key concepts in interactive technology.

The downing of the MH17 reminds the world that the international civil aviation is not as safety and security as people expected. Such tragedy is partly due to the risk and danger of the armed conflict zones, but is more attributed to the ignorance to the international law by the responsible parties concerned. International laws applicable to the armed conflict zones shall be strictly followed, and the reparation shall be provided to the victims, otherwise such disaster could not be avoided in the future.

This paper deals with design procedure of online guidance and control law for future missiles that requires agile maneuverability. For the purpose, the missile with high powered side thruster is proposed. The guidance and control law for such missiles is discussed from a point of view of optimal control theory in this paper. Minimum time problem is solved for the approximated system. It is derived that bang- bang control is optimal input from the necessary conditions of optimal solution. Feedback guidance without iterative calculation is useful for actual systems. In this paper. multiple design point method is applied to design feedback gains and feed forward inputs of the guidance and control law. The numerical results show that the proposed guidance and control law has a high -performance for wide-ranging boundary conditions.

The amount of construction waste increased to 176,447 ton/day in 2008 from 28,400 ton/day in 2000, a 6-fold increase in just 10 years. Such dramatic increase in the waste of concrete, asphalt concrete, wood and metals was due to demolition of old buildings as well as a great number of building redevelopment projects and hurried city industrialization. Many buildings targeted for demolition today were built in line with the government policy to provide affordable housing to citizens in the shortest time possible and consequently, said buildings underwent rapid deterioration and required periodic repairs and reconstruction. Based on the above, we predict that construction waste will continue to increase for the foreseeable future. In particular, due to limited availability of suitable space to construct apartments and residential buildings in the city, old buildings are being torn down to make space for new development, further increasing construction waste. In light of that, efforts to recycle as well as reduce generated waste are urgently required.

In animated films, characters materialize narratives through acting. The narrative is an element to materialize accurate delivery of lines and emotions. The non-verbal actions should express lots of emotions and lines in scenes, and also they can be used as a way of empathy. This study analyzed the visualization factors of narrative focusing on a cat character frequently shown in animated films. For this, the visualization factors of non-verbal actions expressed in characters' personal space and dynamic space were extracted. Based on this, it aims to suggest the emotion expressing method of characters to realize effective narrative visualization. In the future, it aims to be used as reference data in case when producing non-verbal communication for 3D characters.

The era of the fourth industrial revolution, which will bring about a great wave of change in the 21st century, is the age of super-connection that links humans to humans, objects to objects, and humans to objects. In the smart city and the smart space which are evolving further, emotional engineering is a field of interdisciplinary researches that still attract attention with the development of technology. This paper proposes an emotional object prototype as a possibility of emotional interaction in the relation between human and object. By suggesting emotional objects that produce color changes and movements through the emotional interactions between humans and objects against the current social issue-loneliness of modern people, we have approached the influence of our lives in the relation with objects. It is expected that emotional objects that are approached from the fundamental view will be able to be in our lives as a viable cultural intermediary in our future living space.

Space transformation of hospital architecture happens more rapidly than other types such as school and office buildings. This requirement is caused by medical demand, service transformation, technical development and equipment changes. Grand scale extension and rapid change in hospital architecture affects whole planning; therefore, it is important to design in the macro perspective such like Life Cycle. Grand scale extension is difficult process to rebuild growth and transfer of hospital architecture and to adapt to the future change. That's why simple planning gives limits to some departments in a short-term and brings another reform such as more extension or interior renovation in a long-term. This study surveys various space transformation and grand scale extension of EB hospital extended recently, and it is to find planning condition in extension.

The major problem encountered in satellite design is EMI (Electro-Magnetic Interference) and EMC (Electro-Magnetic Compatibility). Here, our focus is on the effects of protons on the electronic system. The SEU (Single Event Upset) results from the level change of stored information due to photon radiation and temperature in the space and the nuclear power plant environment. The impact of SEU on PLD (Programmable Logic Devices) technology is most apparent in ROM/SRAM/DRAM devices wherein the state of storage cell can be upset. In this paper, a simple and powerful test techniques is suggested, and the results are presented for the analysis and future reference. The test results are compared with that of JPL test report. In our experiment, the proton radiation facility available at KIRAMS (Korea Institute of Radiological Medical Sciences) has been applied on a commercially available SRAM manufactured by Hynix Semiconductor Company.
