Leading Lights and Sector Lights provide a navigable channel, heading reference and a visual indication. Mariners can take easily a reference bearing or line of position. The Busan North Port needed to install a sector light to resolve blind sections because of Busan Port Redevelopment Project D-1 Block Construction Plan. And also the busan new port needed to install a sector light to give safety indication because navigation conditions will be changed due to removal of the to-island. For this reason, design development was made for installation of sector lights. In addition, the results of design development were compared with the AtoN simulation and verified. This paper is expected to be very useful for installing Sector Lights to guide the vessel to port safely in Korea.

This study attempts to shed some lights on an effect of consumer education by using the formal education as a proxy variable and measuring the effect of the formal education on consumer behavior. This study utilizes economic theories and develops a theory to analyze the effect. Within the conceptual framework employed in this study, it is hypothesized that education raises productivity in the nonmarket sector and thereby affects consumer behavior in the same manner as money income affects behavior. the data are taken from the self-administered questionnaires among 553 housewives in July 1987. the procedure used is to fit separate engel curves for the expenditures on various goods by the weighted regression technique. The empirical results support the hpothesis. Therefore, this study shows positive effects of education on the productivity of household production functions. This result implies that consumer education would enhance efficiency in consumer behavior significantly.

The study on Electrostatics represents the first scientific interest of human being on electrical phenomena, and it led to enormous progress of electrical and electronic science and engineering up to the current levels. Electrostatics, however, has been long forgotten in the stream of this history as a tribial minor field. Interesting enough, this minor sector has regained recently its new life, in particular in the area of high-technologies, and Electrostatics is going to become one of the most important field in the future of electrical and electronics engineerings. It is impossible to cover the entire trend of this emerging field in a limited space, so that spot lights shall be focused on several important topics in this paper.

Due to the development of technology, the modern people became to require not only more convenient life but also more comfortable and emotional environment, and individually suitable living environment is applied to residents in a residential space. Recently, while the LED lighting was variously attempted in every sector in society, it is needed to express differentiated lighting according to the resident's individual lifestyle in a residential space. In this paper, we analyze the role of LED lighting suitable for the digitalized lifestyle of the modern people through the relevant literature survey and case studies. The following results are obtained in summary of the rapidly changed recent trends of LED lighting. First, LED light replace existing light sources due to the advanced new technology in LED industry, and take the spotlight as a new lighting solution with the development of variable color LED bulb and the control technology by the wired and wireless communications. Second, LED lighting can be structurally applicable to every lighting device because of its compact and lightweight units, can produce abundant light environment by expression of variable colors and moods with the easy coloring and dimming control, can be reborn as emotional lighting design. Third, as recently practices are constantly appeared that integrate LED lights in the interior elements, such as object and furniture, and combine advanced LED lighting technology to new materials, the portion of illumination on the indoor environment is further increased after integrating the LED lighting and interior elements make boundaries of lighting and product architecture become blurred. LED lighting is confirmed that is being changed from the external functionality including material, shape, color, and etc. into the contextual emotion design including the lights expression, variable color, brightness control, making image, and etc. as the light source in current smart lighting era.

This paper examines the use of semiotics for analyzing fashion advertisements in the fast fashion industry. While previous studies have explored the use of semiotics in various industries, the application of this theory in the fashion sector-especially regarding fast fashion's commercial videos related to sustainability-remains underexplored. The paper adopts Roland Barthes' Semiotics Theory to analyze the advertising videos related to the sustainability of major fast fashion brands such as H&M, MANGO, and ZARA. The research approach involved reviewing all commercial videos related to sustainability on these brands' official YouTube accounts and conducting comprehensive analyses of advertisements using the binary opposition analysis framework. The paper's findings indicate that these commercial videos serve as a platform to mold a brand's sustainability image and promote the notion that fast fashion brands are leading the charge toward sustainability, preparing for an unpredictable future, guiding people toward hope, and offering ultimate freedom. This research high-lights the necessity for a critical examination of advertising videos related to sustainability in the fast fashion industry to guarantee accountability and transparency.
