The use of sensors and actuators as a form of controlling cyber-physical systems in resource networks has been integrated and referred to as the Internet of Things (IoT). However, the connectivity of many stand-alone IoT systems through the Internet introduces numerous security challenges as sensitive information is prone to be exposed to malicious users. In this paper, IoT based-security issues ontology is proposed to collect, examine, analyze, prepare, acquire and preserve evidence of IoT security issues challenges. Ontology development has consists three main steps, 1) domain, purpose and scope setting, 2) important terms acquisition, classes and class hierarchy conceptualization and 3) instances creation. Ontology congruent to this paper is method that will help to better understanding and defining terms of IoT based-security issue ontology. Our proposed IoT based-security issue ontology resulting from the protégé has a total of 44 classes and 43 subclasses.

Presently many constructions establish in underwater, but approaching to underwater constructions are difficult, for comparing with ground, underwater environment is different in media. Usually measurement methods for underwater constructions are using tapes, using depth gauges, using acoustic positioning systems. But, tapes are hard to measure the correct distance, for applying a right tension is not easy in underwater. Depth gauges have a weakness in settling, for it takes long time to do it. Acoustic positioning systems don't work well in confined spaces and cost a lot. Hence, the purpose of this study is, at first, to understand rays path in multimedia like water, glass and air. The second thing is to perform a camera calibration at the field to compare with the interior orientation parameter. And the third thing is to find out whether photogrammetry is applied for underwater object in using cube for accuracy examination. The last thing is to perform underwater photogrammetry about underwater object, which is pier model and riverbed. We came to the conclusion through this experiment that the applying underwater photogrammerty for underwater constructions and underwater ground is possible.

Fashion is a cultural element expressing general and common aesthetic awareness in a relevant region in the relevant times. On the aspect that shoes are also a part of fashion reflecting the unique aesthetic awareness of Korea, this paper aims to analyze the aesthetic awareness contained in the aesthetic features observed in the traditional boots. The aesthetic features in terms of the form were the balanced usage of each element including curves, straight lines, simple shapes, contrast colors and materials, and the application and ideological significance as the symbol of social position and status in terms of the contents. Aesthetic awareness pursues the beauty of moderation through the compromise between curves and straight lines, as both elements accept each other's features and keep balance without inclination to one element. Next, solid and void are naturally expressed by appropriately adjusting the expression on colors, materials and shapes through the harmony of composure and techniques. While traditional boots were used as the sign indicating social position and status as the unity of spirit and a thing, they pursue the value of rhythmic vitality by giving spiritual meaning to a thing.

Due to the remarkable improvement of ICT, with the popularization of mobile devices and every sector of society connected by networks, an era, in which peer to peer, peer to thing, thing to thing can be connected to one another everywhere, has begun. As all the electronic devices are connected to Internet, they have become more intellectualized and automated, making convergence and process of information through the connection of the devices possible to provide a lot better services. However, those devices communicate mutually to send information and they are exposed to various security threats. Therefore, this study analyzes ZigBee, CoAP, MQTT, XMPP, which are communication-related technology of IoT, draws security threats they have, and suggests requirements that components of IoT should have. Plus, it examines real cases about security threats in IoT, and suggests a countermeasure so as to contribute to establishment of a basis for IoT to be used much more safely in the future.

This study is a research on the etiology in Wu Youke's wenyi theory. In regard to the etiology of epidemic disease that had been spread on a very large scale at that time, Wu Youke denied the traditional theory which urged the irregular change of climate as the cause of epidemic disease, and proposed the concept of 'zaqi' which was considered by him to be something that could be the real cause of epidemic disease. And He treated the wenyi disease as something that has the same meaning with wenbing, so his concept on wenbing was basically the thing that treats 'zaqi' as the fundamental cause of wenbing and treats the concept of 'wen(溫)' as an environmental cause that could help activate the virulence of 'zaqi'. Such concept like this was the thing somewhat different from the traditional etiological theory that considers the change of climate as the principal cause of waigan(外感)-disease, and it must for the most part have been originated from the experience of Wu Youke himself. But this study, in contrast, based on the thing he denied the traditional theory on the irregular change of climate, has been done in the point of view that fundamental concept of his wenyi theory such as 'zaqi' was not only originated from his clinical experience but also from the influence of paradigm shift in the natural philosophy of that time. There had been so much change in cosmology and natural philosophy from the fundamental basis at that time, and the the most principal concept of it was that there always exists irregular faces in the change of nature. Such concept like this got into its stride from about 17th century, and it was expressed in the form of the severe criticism against the traditional natural philosophy. In regard to this, this study has outlined the academic thought of the leading scholars who made a significant progress in such a paradigm shift, and it includes the scholars like Wang Tingxiang, Wang Fuzhi, Hu Wei, Huang Zongxi, who played their role in the time of the latter period of Ming dynasty and the former period of Qing dynasty.

In Jang-Sang theory, ‘Sang’ indicates ‘Hyung Sang’. The internal organs appear it's shapes(Hyung Sang) outward. ‘Hyung Sang’ is concept that was used on 「the book of changes」(周易) and 「Nei Ching」(內經) to means a thing's shapes and conditions. ‘Hyung’ is the shape, an organization composing a thing and ‘Sang’ is the symptom, an essence(a seed) immanenting a thing. To observe Hyung Sang, it have to apply the principle that ‘the sky and man correspond each other(天人相應)’. Usually ‘Hyung’ appears as shapes and ‘Sang’ appears as colors and conditions. Diagnosis on the basis of Hyung Sang put first the external expression of the five Jang six Bu organs and Jung-Ki-Shin-Hyul(精氣神血). So a doctor has to unite shapes, colors, pulse and symptoms(形, 色, 脈, 症) when diagnosis a patient. The theory of Hyung Sang includes the basic theories of the oriental medicine, the theory for Yin-Yang and the five element(陰陽五行論), organ picture(Jang-Sang), meridians(經絡學說), the five circuit phases and the six atmospheric influences(運氣學說), physical constitution(體質學說). I think that treatment based on Hyung Sang is shown the essence of the oriental medicine well. In the future, I think, we need to study more about the theory of Hyung Sang.
