When we discuss the literature of traditional era in view of ecological mode, Saseol sijo and its common writers were not objects of interests because they were thought only as having the view of the world or nature the same as the noble class and their normal sijo writings had. Also the living things in Saseol sijo were not paid attention to. They were ignored and degraded because they were unfittable and unnatural poetic diction, or they were nonpoetic results of objects. Any critics could not recognize the breathing things as 'the living ones' or 'the subjective things' in the text. In Saseol sijo, the appearance of experienced, substantial and usual animals attract our interest, which is a clue to compare the noble class' sijo with having the ideal and imaginary living things. This study discussed the writer's view and recognition of 'the living things' in Saseol sijo. In this essay 'the living things' mean living and moving creatures. First 'the living things' in Saseol sijo were the creatures of daily life and experience. They were not ideal or dreamy creatures any longer to the writers of Saseol sijo. In Saseol sijo it's possible for creatures which ecological symbiosis cannot be made to appear together. On the contrary there are texts which had outstanding recognition of 'the living things' that were accustomed to the human life. The writers of Saseol sijo understood 'the living things' as creatures familiar to human beings. Their warm and affectionate eyes toward the creatures made 'the living things' the objects of identification and sympathy. There are some works which were complicated with love and hatred toward 'the living things'. In conclusion, the life of Saseol sijo writers were the same as the symbiosis with the living creatures.

Recently, new devices have been developed for the Internet of Things concept. The devices commonly use RF (Radio Frequency) based wireless communication. With the increase in the number of devices, the space allocated for the radio frequency band in wireless communication fills rapidly. Visible Light Communication (VLC) is an alternative, secure and economical communication technology that uses light instead of radio frequencies. While Web of Things (WoT) is the adaptation of the experience and knowledge acquired from the web into the internet of things ecosystems. By combining these two technologies, the development of the Visible Light Communication for Web of Things (VLC4WoT) system, which can use VLC and WoT technologies, has been our motivation. In our study, microcontroller control circuit was created for VLC4WoT system. Control of the circuits over the internet was performed. VLC based receiver and transmitter units have been developed for wireless communication. Web based interface was created for control. The test apparatus consisting of four objects with four outputs and a transfer unit was carried out. In this test, communication was achieved successfully. It was presented in the study that VLC can be used in the web of things architecture. In the future, it is envisaged to use this system as a safe and economical system in indoor environments.

This study aims to apply the concept of Internet of things to library and interpret a library as ecological space where human, thing and data are communicating and organically networking through internet. First, we defined various things existing in physical spaces of the real world and internet spaces as elements of Internet of Things. Then we proposed to apply a semantic web platform to integrate different meta-data formats and communication protocols from things. Finally, we provide the model of Internet of Things based on Semantic web to utilize a variety of information from things for library management and user service.

Internet of Things(IoT) is electronic devices and household appliances use wireless sensor network in environment of high speed wireless network and LTE mobile service. The combination of the development of Internet and wireless network led to development of new forms of service such as electronic devices and household appliances can connect to the Internet through various sensors and online servers such as a Home Network. Even though Internet of Things is useful, there are problems in Internet of Things. In environment of Internet of Things, information leakage could happens by illegal eavesdropping and spoofing. Also illegal devices of wireless communication interference can cause interfere in Internet of things service, physical damage and denial of service by modulation of data and sensor. In this thesis, it will analyze security threats and security vulnerability in environment of mobile services and smart household appliances, then it will suggest plan. To solve security issues, it is important that IT and RFID sensor related companies realize importance of security environment rather than focus on making profit. It is important to develop the standardized security model that applies to the Internet of Things by security-related packages, standard certification system and strong encrypted authentication.

Recently, Internet of Things (IoT) have become popular for research and development in many areas. IoT makes a new intelligent network between things, between things and persons, and between persons themselves. Social network service technology is in its infancy, but, it has many benefits. Adjacent users in a social network tend to trust each other more than random pairs of users in the network. In this paper, we propose recommendation technique using social network in Internet of Things environment. We study previous researches about information recommendation, IoT, and social IoT. We proposed SIoT_P(Social IoT Prediction) using social relationships and item-based collaborative filtering. Also, we proposed SR(Social Relationship) using four social relationships (Ownership Object Relationship, Co-Location Object Relationship, Social Object Relationship, Parental Object Relationship). We describe a recommendation scenario using our proposed method.
