This study intended to discover the communicative characteristics of libraries, such as locality, communality, interactivity, and organic vitality, and measure as to whether the components constituting them were appropriate, and based on the research results, it was intended to establish the role of public libraries based on communicative characteristics. As a result of the study, it finally turned out that the libraries had the four communicative characteristics of 'locality', 'communality', 'interactivity', and 'organic vitality'. The four communicative characteristics may be classified into 16 factors and 63 detailed factors accordingly. Examining the characteristics of library communication, first, locality means that local residents create and maintain the identity of a social, historical, and cultural locality while sharing the space of a library. In the library, the users can receive local life information or create a cultural identity of the locality through communication between the users. Second, communality is a fundamental factor in forming a community of local residents and represents the characteristics of a group formed based on place and geographical characteristics, culture and belief system, and interests. Third, interactivity refers to a kind of behavior in which users interact with other users, information providers, and books and information in the library to give and receive influence. The actions in which two or more objects share knowledge, thoughts, emotions, and opinions may be seen as being accomplished through interaction. Lastly, organic vitality means seeking the continuous maintenance and development of the community, and creating a lasting characteristic even in the changing environment of the library.

In the case of public buildings, fast communication and transparency in the administration and the public, as well as ensuring visibility and lighting performance using a glass curtain wall is symbolically expressed through the transparent glass skin. This study is a simulation in order to derive the basic data for the establishment of the improvement of the heating and cooling load analysis according to the window area ratio changes with respect to the high effectiveness of the government's large public building energy consumption analysis and green building certification system of guidelines was analyzed by a change in the energy load. Glass curtain wall is light and visibility, the symbolic meaning of communication, etc., but is widely used in a variety of characteristics, in terms of energy consumption being disadvantaged sheath plan should have been. Design, including the Atrium, is much less energy than energy consumption by the window area ratio. Thus, while compliance with design guide lines, the atrium and I like the burden of a large space ratio and energy load consists of only glass suggest that require more research on that given in the guidelines.

English is the accepted common working language of the maritime world and being competent in its use is essential to the safety of ships, their crews and the marine environment. This paper is a response to the urgent need to find a suitable solution to the problem of providing maritime students with quality instruction in Maritime English. This paper will show what type of English instructor is best suited to help cadets have at least a basic grasp of Maritime English communication, with a view to possessing the level required by STCW 95 within the shortest time. It presents ways that maritime institutes can develop their own qualified or 'marinated' English Instructors and what qualifications should be required. It is concluded that by further essential research, interviews and questionnaires etc., the language needs of the university and shipping industry in Korea as a whole can be clearly verified. By examining such data, the present language education systems can be evaluated as to efficacy and relevance, allowing the establishment and implementation of 'best practice' within the training institute. This will result in making excellent informed decisions and choices about how best to improve the language competencies of graduating cadets, thereby creating the catalyst for the success of future seafarers whilst raising the image of the institute and Korean shipping worldwide.

Conventional underwater cameras used in fish farms can only shoot limited areas and are vulnerable to underwater contamination. There is also a problem with contaminated farms as surplus residues are deposited as a result of feed supply to farms' nets. This paper proposes underwater drones for underwater monitoring of fish farms and cleaning nets. If underwater drones are used for management of fish farms, underwater imaging, monitoring and cleaning of fish farms' nets can be possible. By using this technology, data can be collected by detecting changes in the environment of a fish farm and responding to changes that occur within a fish farm based on the data. In addition, the establishment of an integrated control system will enable to build efficient and stable smart farms.

Accurate and rapid establishment of mobile communication is important in mobile communication system. Currently, the base station parameters to establish a network are determined by cell planning tool. However, it is necessary to perform new cell planning for each new installation of the base station, and there may be a problem that parameters are not suitable for the actual environment are set, such as obstacle information that is not applied in the cell planning tool. In this paper, we proposed methods for path loss prediction using DNN and topographical division using CNN in SON server. After topography classification, a SON server configures the base station parameters according to topography, and update parameters for each topography. The proposed methods can configure the base station parameters automatically that are considered topography information and environmental changes.

Ubiquitous sensor network is to manage and collect information autonomously by communicating user around device. Security requirements in Ubiquitous based on sensor network are as follows: a location of sensor, a restriction of performance by low electric power, communication by broadcasting, etc. We propose new mutual authentication protocol using a low power of sensor node. This protocol solved a low power problem by reducing calculation overload of sensor node using two steps, RM(Register Manager) and AM(Authentication Manager). Many operations performing the sensor node itself have a big overload in low power node. Our protocol reduces the operation number from sensor node. Also it is mutual authentication protocol in Ubiquitous network, which satisfies mutual authentication, session key establishment, user and device authentication, MITM attack, confidentiality, integrity, and is safe the security enemy with solving low electric power problem.

The required standards for environmental tests for communication and electronic equipment used currently in the army are not standards into which the Korean climate and use environment are taken into consideration. But the environmental testing standards of the U.S. army at the time of its establishment(MIL-STD-810) “A” version has been used without taking into consideration the Korean domestic situation and conditions by simply translating the US standards. Adherence to these standards may limit the ability to supply materials in case of emergency since the increase in the manufacturing costs according to excessively strict standards induces an increase in the acquisition cost of military equipment, unnecessarily high maintenance and repair expenses are consumed, and stocks of parts for the military use have to be retained at all times.
