Greenhouse gas (GHG) emissions from dye wastewater treatment processes were estimated by analysing their mass and energy balances, which were then used as baseline information for environmental assessment. The total GHG emissions from dye wastewater treatment plants were divided into direct emissions from the treatment processes and indirect ones from electricity usage. The amounts of $CO_2$, $CH_4$ and $N_2O$ emissions were calculated according to the Intergovernmental Panel on Clime Change (IPCC) guideline for the GHG target management system. For 3 years between 2011 and 2013, direct and indirect emissions were on average 8,742.7 and 7,892.0 Ton.$CO_2eq/year$, respectively, with the former exhibiting 52.6 %. Also, compared to 2012, in 2013, the eco-efficiency indicator by the GHG emissions was found to be more than 1, suggesting that environmental quality was effectively improved.

In Korea, the guideline for the bridge safety inspection requests to assess surface degradation, including crack, efflorescence, spalling, and so on, for the rating of concrete bridges. Currently, the assessment of efflorescence is performed based on the visual inspection of expertized engineers, which may result in subjective inspection result. In this study, a novel method using a hyperspectral camera is proposed for objective and accurate assessment of concrete efflorescence. The hyperspectral camera acquires the light intensity for a number of continuous spectral bands of light for each pixel in an image, which makes the hyperspectral imaging technique provides more detailed information than a color camera that collects intensity for only three bands corresponding to RGB (red, green, and blue) colors. A stepwise assessment algorithm is proposed based on the spectral features to decompose efflorescence area from the inspected concrete area. The algorithm is tested in the laboratory test using two concrete specimens, one of which is dark colored with efflorescence on a surface while the other is bright concrete without efflorescence. The test shows high accuracy and applicability of the proposed efflorescence assessment using a hyperspectral camera.

This study was jointly conducted by the department of nursing science in a college of natural sciences and the furniture design department in the art and physical education to research the critical factors for the furniture development for the Elderly in consideration of the surging number of senior citizens not only in Korea but also globally. On the basis of the Elderly's physical and mental characteristics investigated by the department of nursing science, the furniture design guideline for the Elderly was presented. The following points should be considered at designing the furniture for the Elderly. First, multiple functions like chair with removable toilet bowl and part lighting in bed are advantageous. Second, the dimension of furniture such as chair, bed and sofa should be ergonomically thought in terms of structure for the Elderly's convenience. Third, the bright and vivid color of furniture should be chosen from the aspect of the design, while the different kinds of blue should be avoided. Small patterns and high glossy are not recommendable, but various kinds of feelings in different shapes are suggested. Forth, the material should contribute to the fracture prevention and for that sponge, fabric and leather smoothing the surface of furniture are recommendable as the finishing treatment in a wide variety of colors.

According to the rapid change in the era of Korea, there have been significant changes in the buildings and facilities in the rural area of the country, and thus in the landscape of the agricultural and fishing villages due to the painting of colors that are not in harmony with the surrounding natural environment. Recently, the value recognition on the rural landscape has greatly changed and studies are actively performed on rural colors. To keep up with this trend this study is intended to propose coloring plan of Byutgari and Eumpo area for their entire landscape including the facilities to harmonize with their natural and cultural characteristics and surrounding environments. This plan was related to the establishment of the landscape planning of the region in Taean-gun, Chungcheongnam-do, based on the already prepared rural environmental coloring guideline. This study has its significance in that it provided a coloring process that can be applied to the targeted are as well as other area, continuing the context of the precedent studies. It is greatly expected that the regional characteristics will be strengthened owing to the establishment of coloring guidelines.

We experimented on AGV driving test with color CCD camera which is setup on it. This paper can be divided into two parts. One is image processing part to measure the condition of the guideline and AGV. The other is part that obtains the reference steering angle through using the image processing parts. First, 2 dimension image information derived from vision sensor is interpreted to the 3 dimension information by the angle and position of the CCD camera. Through these processes, AGV knows the driving conditions of AGV. After then using of those information, AGV calculates the reference steering angle changed by the speed of AGV. In the case of low speed, it focuses on the left/right error values of the guide line. As increasing of the speed of AGV, it focuses on the slop of guide line. Lastly, we are to model the above descriptions as the type of PID controller and regulate the coefficient value of it the speed of AGV.

The purpose of this study is to produce an essential guideline for making costumes for traditional Korean mask plays by doing a comparative analysis between traditional Korean mask plays and Italian 'Commedia dell'arte'. The results of this study are as follow. The costumes of Korea's mask plays were mainly used to show difference in social status. Analysis showed that costume features, such as color, fabric, and silhouette, were not important to the traits of the character. On the other hand, the costumes in the Italian 'Commedia dell'arte' were used to express the characters' traits. The colors, fabric and silhouettes were exaggerated compared to everyday wear. This enhanced the looks of the character, and it kept on developing with the demands of the culture consumer. This study was performed to support further development and success of traditional Korean mask plays.

This paper analyzes qualitatively the stereo 3D content factors causing viewer's discomfort. For this, we perform a subjective test that each subject strokes a specific key whenever he (she) feels discomfort during watching a stereo 3D contents. Also we extract the data for the factors in the 3D contents to obtain their quantitative values and the amounts of the temporal changes. Those two sets of data are used to analyze the contents to find the factors which cause viewer's discomfort. The factors to be considered are the amount and the frequency of the disparity changes, story of the contents, situation or environments of a scene, movement and the position of the camera, color and luminance information as well as disparities themselves. We analyse the various strong and weak factors and their composites to find how much discomfort each factor or composite causes. We also show the situations and their related factors that causes less discomfort than the amount of their disparities.

In comparison with some other light sources, LED has merits such as increased life expectancy, fast response, pollution free, and high energy efficiency. Lately, due to development of LED with high brightness and capacity, LED has widely used in many industrial fields such as automotive, aviation, display, transportation and special lighting applications. Since the high heat generation of LED chips can cause a reduction in lifetime, degradation of luminous efficiency, and variation of color temperature, studies have been carried out on the optimization of LED packaging and heat sinks. In this study, experiments on measuring the heat generation rate of LED and the cooling performance of a heat sink were carried for analyzing the thermal characteristics of LED lighting system in free convection. From the results, dimensionless correlation on the cooling performance of heat sink in natural convection was proposed with Nusselt number and Rayleigh number as a guideline for designing cooling device of LED lightings.

Purpose : The purpose of this study was to identify minimum data sets for oral mucous integrity-related documentation and to analyze nursing records for oral care. Methods: To identify minimum data sets for oral status, the authors reviewed 26 assessment tools and a practical guideline for oral care. The content validity of the minimum data sets was assessed by three nurse specialists. To map the minimum data sets to nursing records, the authors examined 107 nursing records derived from 44 patients who received chemotherapy or hematopoietic stem cell transplantation in one tertiary hospital. Results: The minimum data sets were 10 elements such as location, mucositis grade, pain, hygiene, dysphagia, exudate, inflammation, difficulty speaking, and moisture. Inflammation contained two value sets: type and color. Mucositis grade, pain, dysphagia and inflammation were recorded well, accounting for a complete mapping rate of 100%. Hygiene (100%) was incompletely mapped, and there were no records for exudate (83.2%), difficulty speaking (99.1%), or moisture (88.8%). Conclusion: This study found that nursing records on oral mucous integrity were not sufficient and could be improved by adopting minimum data sets as identified in this study.
