Emergency lights and exit signs are an indispensable part of safety precautions for effective evacuation in case of emergency in public buildings. These emergency sign indicates safe escape routes and emergency doors, using an internationally recognizable sign. However visibility of those signs drops drastically in case of emergency situations like fire smoke, etc. and loss of visibility causes serious problems for safety evacuation. This paper propose a novel emergency light and exit sign built-in with Bluetooth Low Energy (BLE) Beacon to assist the emergency self-guiding evacuation using devices for crisis and emergency management to avoid panic condition inside the buildings. In this approach, the emergency light and exit sign with the BLE beacons deployed in the indoor environments and the smart devices detect their indoor positions, direction to move, and next exit sign position from beacon messages and interact with map server in the Internet / Intranet over the available LTE and/or Wi-Fi network connectivity. The map server generate an optimal emergency exit path according to the nearest emergency exit based on a novel graph generation method for less route computation for each smart device. All emergency exit path data interfaces among three system components, the emergency exit signs, map server, and smart devices, have been defined for modular implementation of our emergency evacuation system. The proposed exit sign experimental system has been deployed and evaluated in real-time building environment thoroughly and gives a good evidence that the modular design of the proposed exit sign system and a novel approach to compute emergency exit path route based on the BLE beacon message, map server, and smart devices is competitive and viable.

Child labor is being recognized as the key issue of human rights, and the International Labor Organization and the Convention on the Rights of the Child emphasize that children are individuals with dignity and rights. Male and female child actors belong to a profession with wide public exposure and there is a potential danger of invading classes and roles not matching the developmental stage of the child. In this study, we would like to discuss international and domestic laws and future complementary measures surrounding legal and institutional issues that need to be considered for child actors. Although the basic rights for child workers are stated in the Constitution Article 32 Paragraph 5 and Labor Standards Act Articles 64 through 70, they are insufficient. Following the revised broadcasting deliberation regulations by the Korea Communication Commission and amendment of the Juvenile Protection Law, several changes are taking place in the working environment. In certain foreign places such as California, United States, the economic and educational rights of male and female child actors are being protected. Although legal and institutional frameworks for the male and female child actors are being reinforced, more consistent devices are needed. Consideration for working hours, regulations to keep up with learning while working, and preparation for physical and emotional influences are required to keep up with international changes.

This study has analyzed the characteristics of the French method of childrearing which is drawing attention recently based on the psychoanalytic theory of François Dolto, the so-called French people's godmother, the child psychoanalyst. Dolto is a psychoanalyst who represents France and is the unique character who was loved by the public and established unique frame of child psychoanalytic analysis by combining psychoanalysis and pediatrics. She cherished communication through conversation with infants and toddlers and has perceived even the babies who can not speak yet as a lingual being who understands words. This study has selected domestically published books on French method of childrearing and documentary broadcasting program which dealt with childrearing, classified the common theme and deducted four core words, which are temperance, perseverance, waiting, autonomy and rule, authority and respect and independence and self-reliance. These core themes have been explained based on Dolto's theory of communication, infans, castration, subject and others and desire etc. Also, a new direction has been proposed for the child education in households and childrearing by Korean parents through French method of childrearing.

They do the image making, color consulting, and education for individuals and business. Second, professional image consulting education is carried out not only in the 93 private companies, but also in the continuing and professional studies for adults of 10 universities. Furthermore, more then 90 universities have specific academic programs related to the image consulting such as facial management, beauty coordination, cosmetology, stylists, fashion events, broadcasting stylists, and so on. Third, a typical image consulting job is the personal shoppers who assists VIP customers in department stores. Professionals and politicians have personal fashion stylists for their image making. Today, the job has expanded to public fashion therapist. Fourth, the contents of an image consulting education have appeared in similar industries and educations. These contents include fashion styles, personal color analysis, make-up, facial expressions, gestures, perfumes, accessories, etc. This study is based on research on the current Korean image-consulting industry, and will enable follow-up details to be implemented. using the basis of this study for a strategic self-image formation system.

These days, with the advent of digital broadcasting, media environment offers users an opportunity to enjoy differentiated contents in a more aggressive fashion through user-media interactions based on computer technology. In fact, the development of contents which can induce spontaneous acts from users such as outdoor ads which use certain sensors and devices and exhibition halls has been active. With the development of low-price motion recognition devices, people have been able to enjoy diverse interaction-applied media by recognizing users' motion data without body contact. In this paper, we developed an interactive media player that can recognize the user's motion and control the video in the web service environment without installing a specific program. In addition, we set user motion recognition range and developed a user motion recognition algorithm suitable for the Leap Motion equipment installed in the kiosk. The results of this study can be experienced by various interactive media such as interactive tourism, education, and movie contents in kiosks that can be installed in public places.

Demand for spectrum resources is increasing with the development of mobile telecommunications and so is their economic value. As a way to enhance the economic efficiency of use of spectrum resources, many countries have focused on the management of public and broadcasting spectrums which have traditionally been undercharged compared to their economic values. In this paper, we discuss the economic value valuation of the frequencies for the fisheries communications. The estimated value is the average value of the total equipment cost of the mobile communication services that their service coverage is nation-wide, and the value that adjusted the auction price for the LTE service frequencies in 2011 to the characteristics of fisheries communications.
