Recently, the cameras which used for observation are installed in children protection area and local crime prevention area in order to protect life and property and by its work being recognized and are installed more. Normal cameras have cost problem to observe multiple area and detail, because they can observe only one place. PTZ camera can observe multiple area by moving focus by schedule or remote control, but it can't automatically move the focus of it to the place where event occurred, because it can't recognize the place. In this study, we can monitor multiple area effectively, by installing a wireless sensor node equipped with temperature, lighting, gas and human detection sensor to each area, to monitor many place low-price and actively and to move the focus of PTZ camera to preset position, and send recorded video to the user, when the various sensor data received from wireless sensors in observation area are to be determined abnormal by analyzing. In addition, at night we can record a scene using infrared, but to reduce power consumption of lighting system which are installed to improve resolution, it supplies power to the lighting system when event occurred. So we were able to implement low power green monitoring system.

Cordyceps and its allies fungi has been described as a secret medicine that gives eternal youth and a long life. Some species of Cordyceps are sources of biochemicals, such ascordycepin, with interesting biological and pharmacological properties. Hence, it has been studied to uncover its pharmacological effect. We attempted to study the formation of fruiting bodies and to develop means of mass production Korean isolate of Paecilomyces tenuipes has been inoculated into silkworms, where it reproduced using culture container, mini-kit successfully. Culture container, mini-kit is composed of a cylinder-shaped body and lid. The container is made of translucent polyethylene terephthalate. The size of the container is $82{\times}75mm$, reduced by 10 times as compared with the conventional culture kit. The mini kit has many advantages - high culture amount, ability of maintaining optimal humidity, parasite-free cultivation and high-end appearance. With the kit, the optimal cultivation condition is under $22^{\circ}C$, culture period of 53 days. And synnemata of P. tenuipes could be kept fresh for 14 days at the temperature of under $10^{\circ}C$. Therefore, the Min-kit can be used in both ways as a culture container and a packing kit for end-user customers.

In the era of the rapid development of a tremendous number of new technologies and products, the emotional communication between products and users has become an important research topic. However, the user's emotional measurement methods have not been widely used in the field of product design. Besides, as an important space that can improve people's life quality and urban entertainment at the emotional level, seaside space also creates an atmosphere of frequent emotional communication among tourists, landscape and environmental facilities. To deduce the applicability and advantages and disadvantages of the experiential emotional measurement method in product design, this paper took the seaside seat users of Haeundae as the object and carried out the Self-report of the experiential emotional measurement method. Specifically, the experiment of Self-report was divided into two stages: prior survey and subsequent main investigation. Then the hypothesis was verified by using Bivariate Regression and Multiple Regression through SPSS. Furthermore, through the experiment of the Self-report, the applicability and advantages and disadvantages of experiential emotional measurement method in product design were derived. In the future, based on the applicability, advantages and disadvantages of the experiential emotional measurement method derived in this study, it is expected to become the fundamental and reliable data for the development of emotional measurement methods that can be suitable for product design.

Point of interest (POI) of the city is a special place that has what importance to the user. For example, it is such landmark, restaurants, museums, hotels, and theaters. Because of its role in the social and economic life of us, these have attracted a lot of interest in location-based applications such as social networks and online map. However, while it can easily be obtained through the Web, the basic information of POI such as geographic location, another effort is required to obtain detailed information such as Wi-Fi, accepting credit cards, opening hours, romper room and the assessment and evaluation of other users. To solve these problems, a new method for correcting position error is required to link location-based social network service (LBSNS) data and POIs. This paper attempts to propose a position error correction method of POI and LBSNS data to enrich POI information from the vast information that is accumulated in LBSNS. Through this study, we can overcome the limitation of individual POI information via the information fusion method of LBSNS and POI, and we have discovered the possibility to be able to provide additional information which users need. As a result, we expect to be able to collect a variety of POI information quickly.

This study includes services that require six professional guides - health care, exhibition performance, restaurant, shopping, business and daily life - as well as a trip-based tour, along with solving existing problems that may occur on domestic and overseas trips, and proposes services that connect users with proven professional guides. As a result of previous research, the most needed services among overseas travel were air tickets, accommodation, transportation, and guides, but as Korea enters an aging society, professional guide services are expected to increase daily demand. Based on this, the service technology, user scenarios and brand development were presented. This Service Proposal provides users with a personalized guide to knowledge or experience that they have not previously known, providing them with a wealth of experience. In addition, guides can help develop new fields of expertise and help improve professional guides' capabilities. Finally, the platform service is meaningful in that it enables the creation of jobs by enabling everyone to engage in economic activities, as it allows users to provide services through their own capabilities while at the same time being convenient for them.

Broadcasting and audiovisuals are the easiest audiovisuals to access in everyday life and are shared through the media by recording the times. Overseas, independent broadcasting and audiovisual archives are already in operation under the legal system. As the domestic broadcasting and audiovisual industries continue to grow in size and are drawing global attention, the establishment and operation of public broadcasting and audiovisual archives need to be discussed in more detail. In particular, it is clear that the legal device is a task that must be preceded as the basis for the establishment of public broadcasting and audiovisual archives. To this end, this study first looked at the Digital Archive Center, which was operated in the 2000s. In addition, the cause of the dismantling of the Digital Archive Center was considered as the absence of a legal device, and the case of the Institut national de l'audiovisuel(INA), which has been operating on a legal basis for a long time, was investigated. INA is a representative example of implementing a lead-based system in the broadcasting and audiovisual fields, and has been introduced several times through previous studies, but tends to be focused on user services. Therefore, in this study, the analysis was focused on legal factors supporting the operation of INA. Finally, in order to realize the Public Broadcasting and Audiovisual Archive discussed in the previous study, I would like to suggest a legal device for the establishment of Public Broadcasting and Audiovisual Archive in Korea.

The protection of fundamental rights of people is a natural duty of a state. Since Constitutional Law declare that a state is obliged to protect the fundamental rights of people obviously, it is reasonable to postulate that a state has a duty to protect every person's right much more positively. Of course, it is true that whereas right of freedom is much more important in modern states, the social right becomes more important currently. Nevertheless, we have no choice but to put an emphasis on the importance of the right of freedom like modern states. Thus states are still bound to try to protect the right of people, specific duty of behavior for the sake of right of freedom belongs to states. In particular, due to the fact that lifts are essential to our comfortable life and the demage from the accident concerning with the lifts is fatal, the strategy for securing the safety of using the lifts is significant to some extent. And because it is true that the experience of UK that put an emphasis on the role of civil actors is meaningful to us, there seems implications for us. Accordingly, it is possible to consider the material components such as the check of safety before installation for the sake of safety enhancement, quality control for lifts parts, specification of check criterion and variation of check cycle etc. and personal ones such as specification of qualification of competent persons, guarantee of competent person's independence, variation of obligator's duty and variation of user's obligation etc. However, as the situation of UK is one thing and that of Korea is another, we don't have to adhere to the policy and the experience of UK strictly. Rather, we had better apply the policy and experience of UK to ours appropriately.

Based on the Everyday Information Seeking Behavior Theory, this study investigates information activities and library experience of 66 elderly or people with disabilities in Autonomous District A. In addition, this study analyzes contextual circumstances of daily information activities through in-depth interviews with a subset of 11 people. Although community welfare centers provide basic welfare, the elderly and people with disabilities seek to learn and socialize in cultural welfare centers, particularly in libraries. This study shows that libraries can fulfill their top three of Maslow's hierarchy of needs: Self-Actualization, Esteem, and Love and Belonging. Specifically, digital literacy education has been identified to be highly demanded. They seek to distinguish correct online information and to socialize using digital technologies in this contactless society. This study proposes a detailed plan for public libraries to offer cultural and information welfare in order to reduce the information gap within the local communities.
