Korean commercial architecture is based on two distinctive characteristics of western modern architecture: grid frame structure and free facade. However, the original facade of the building disappears as numbers of commercial advertisements and signboards representing inner programs cover up the original facade. This is a unique feature of commercial architecture in Korea which I would call the surface phenomena of Korean commercial architecture. Common criticism on this type of building is that too many and too big signboards infringe upon the original pure facade of the architecture. Underlying assumption here is that signboards and commercial ads are inessential and decorative elements simply attached to the original pure facade of modern architecture. However, in this paper, I argue that commercial decorations is an essential aspect of korean commercial architecture rather than an inessential decorative element attached later to the essential facade of architecture and that it reflects the historical specificity of cultural and architectural modernity of Korea And thus, the surface phenomena of Korean commercial architecture should not be judged based upon the aesthetic paradigms of either western modern or postmodern architecture. Rather, it can be argued that surface phenomena of Korean commercial architecture is a reflection of a modernity beyond the paradigm of western modernism and postmodernism. The agenda of Korean commercial architecture is then not simply to restrict or to control signboards on the building facades with the intention to clean up facade of the building but rather to integrate the signs and commercial ads with the structure of architectural surface.

Over the past several years, sea trade have increased traffic by ships which highlighted a problem of unwanted species invading the surrounding seas through ship's ballast water discharge. Maritime trade volume has continuously increased worldwide and the problem still exists. The respective countries are spending billions of dollars in an effort to clean up the contamination and prevent pollution. As part of an effort to solve marine environmental problem, BWM(Ballast Water Management) convention was adopted at a diplomatic conference on Feb. 13 2004. In order to comply harmoniously this convention by each country. This convention will be effective after 12 months from the date which 30 countries ratified accounting for more than 35% of the world merchant shipping volume. On Sep. 8 2016, Finland ratified this convention and effective condition was satisfied as 52 states and world merchant vessel fleet 35.1441%. Thus, after Sep. 8 2017, all existing vessels shall be equipped with BWTS(Ballast Water Treatment System) in accordance with D-2 Regulation, which physically handles ballast water from ballast water exchange system(D-1 Regulation). In this study, we analyzed in detail the optimal design method using the Risk Analysis and Evaluation technique which is mainly used in the manufacturing factory or the risky work site comparing with the traditional design concept method applying various criteria. The Risk Assessment Method is a series of processes for finding the Risk Factors in the design process, analyzing a probility of the accident and size of the accident and then quantifying the Risk Incidence and finally taking measures. In this study, this method was carried out for Electrolysis treatment type on DWT 180K Bulk Carrier using "HAZOP Study" method among various methods. In the Electrolysis type, 63 hazardous elements were identified.

Objectives: This study was performed to evaluate the total dust, size-selective dust, and heavy metal concentrations generated inside and outside toll booths on an expressway and to identify the source through analysis of the components of the deposited dust. Methods: A total of 32 samples were collected from eight expressway toll booths. Each total dust sample was collected using a 37 mm PVC filter attached to a personal air sampler. Heavy metal samples were collected according to NIOSH method 7300. The size-selective dust concentrations were identified using a DustMate, and deposited dust was analyzed by WD-XRF and UHR-FE-SEM. Results: The geometric mean concentrations of the total dust inside and outside the toll booths were 337.5 ㎍/㎥ and 342.7 ㎍/㎥, respectively. The overall concentrations of TSP, PM₁₀, PM_2.5, and PM1 were higher on the outside of the toll booths, as the particle size of dust was larger, and higher in the underground passage as the dust size was smaller. The real-time analysis of the dust concentrations of TSP, PM₁₀, PM_2.5, and PM1 revealed to be higher at morning and evening times than other times because of heavy traffic. The element components of deposited dust in the toll booth were related to natural sources rather than artificial sources. Among the chemical components in the deposited dust analyzed by WD-XRF, SiO₂ was the highest. For the elements analyzed by UHR-FE-SEM, C was the highest, followed by O, and Si. Conclusions: In order to reduce the dust concentrations around toll booths on an expressway, it is necessary to periodically clean surrounding areas such as underground passages, and it is also necessary to remove deposited dust inside the toll booth from time to time.

This study deals with the fabrication and thermal characterization of planar heating elements attached to the backside of the reflector used in the electrodeless lamp of a freezer. We tried to solve the problem of the local heat generation of the linear heating element that occurs about 50℃. The homogeneous dispersion and manufacturing excellence of the planar heating element produced were confirmed through SEM and EDS. In addition, the test specimens was prepared according to the change in the ratio of carbon fiber to the basis weight of the planar heating element, and a sample having a basis weight of 50g/㎡ having a content ratio of carbon fiber of 70% was selected. That sample showed low surface resistance of 4.3Ω/sq and high temperature of about 81℃ at 6V. Durability was confirmed by performing repeated bending evaluation of 3000 cycles for the sample. Large area test specimens were prepared to be applied to the actual reflector, insulated by EVA film and analyzed for their thermal characteristics. From 13V application, the temperature of the linear heating element was higher than 50℃ and the average temperature of 68℃ was maximum at 18V.

Elementary school's physical environment is critical to lower grade students. Among the many physical conditions, Toilet, which belongs to health and sanitation category is very important to those who start school for the first time. The purpose of this study is for suggesting the guidelines of toilet design reflecting psychological and behavioral aspects of lower grade students. The research was executed as follows. Firstly, focused survey groups were carefully chosen. Five elementary schools were selected, being all open after 2005 under Seoul Gangseo District Office of Education. Secondly, field study was executed to find out toilet usage, during the period between April to June 2012, by visiting schools to see basic facilities, taking pictures and making actual measurement in each toilets. The architectural analysis was focused on location, moving line, actual size and space zoning, while the interior analysis being on finishing materials and the design of sanitary equipments. And the design elements such as color, lighting fixture, art works or signage were analysed, too. Finally, questionnaire survey was done to find out preferences of lower grade students. As a result, the guidelines of toilet design can be divided into two main parts, Physical and Psychological. For the Physical part, it is necessary for related facilities to be concentrated in order to give easy access. In addition, good ventilation, better lighting and to install sanitary equipments ergonomically are required. Furthermore, safe and clean maintenance should be considered. Psychologically, the design should be directed for making lower grade students come to toilets with comfort and more pleasantly.
