The role of the financial institution to promote corporate sustainability may be reviewed in two angles, as a commercial lender and an investor. As a commercial lender, financial institutions should minimize the legal risks and the political risks. Financial institutions began to recognize environmental risks as legal risks that directly affect their lending practices since the legislation of the Comprehensive Environmental Response, Compensation, and Liability Act("Superfund") of the U.S.A. The so-called lender liability rule has a detailed guideline where the financial institutions may be exempted from the Superfund Liability. Similar attempts are noticed in the recent EU White Paper on Environmental Liability. In Korea, comprehensive environmental liability laws are yet to be developed. The Soil Environment Preservation Act now includes a far-reaching environmental liability provisions, where the owners and operators as well as receivers of the facility bear responsibility. However, whether the financial institutions may be captured as a potential responsible party is not very clear. Until the relevant legislation is developed and court decisions accumulate, Korean financial institutions are well advised to raise awareness on this issue, to develop environmental policies and to train personnels.

Stress adversely affects the wellbeing of commercial chickens, and comes with an economic cost to the industry that cannot be ignored. In this paper, we first develop an inexpensive and non-invasive, automatic online-monitoring prototype that uses sound data to notify producers of a stressful situation in a commercial poultry facility. The proposed system is structured hierarchically with three binary-classifier support vector machines. First, it selects an optimal acoustic feature subset from the sound emitted by the laying hens. The detection and classification module detects the stress from changes in the sound and classifies it into subsidiary sound types, such as physical stress from changes in temperature, and mental stress from fear. Finally, an experimental evaluation was performed using real sound data from an audio-surveillance system. The accuracy in detecting stress approached 96.2%, and the classification model was validated, confirming that the average classification accuracy was 96.7%, and that its recall and precision measures were satisfactory.

Many studies are undertaken into nuclear power plants (NPPs) in preparation for accidents exceeding design standards. In this paper, we analyze the applicability of various wireless communication technologies as accident countermeasures in different NPP environments. In particular, a commercial wireless communication module (WCM) is investigated by measuring leakage current and packet error rate (PER), which vary depending on the intensity of incident radiation on the module, by testing at a Co-60 gamma-ray irradiation facility. The experimental results show that the WCMs continued to operate after total doses of 940 and 1097 Gy, with PERs of 3.6% and 0.8%, when exposed to irradiation dose rates of 185 and 486 Gy/h, respectively. In short, the lower irradiation dose rate decreased the performance of WCMs more than the higher dose rate. In experiments comparing the two communication protocols of request/response and one-way, the WCMs survived up to 997 and 1177 Gy, with PERs of 2% and 0%, respectively. Since the request/response protocol uses both the transmitter and the receiver, while the one-way protocol uses only the transmitter, then the electronic system on the side of the receiver is more vulnerable to radiation effects. From our experiments, the tested module is expected to be used for design-based accidents (DBAs) of "Category A" type, and has confirmed the possibility of using wireless communication systems in NPPs.

This research analyzed the effect of a basic environmental facility siting on the difference in land prices using a case study of Jisan sewage disposal plant in Daegu metropolitan city. To do so, two buffer zones were generated around Jisan sewage disposal plant to 400m at an interval of 200m as a setback distance and 822 officially announced individual land prices were acquired from Korea Ministry of Land, Infrastructure and Transport(MOLIT). Paired samples t-test was performed to compare the mean difference in land prices before and after Jisan sewage disposal plant siting. Results show that the mean land price from each buffer zone was slightly increased after the siting and the difference was statistically significant. Also, the results indicate that the mean land price within 200m was lower than that between 200m and 400m before the siting while there was not different in the mean land price for both buffer zones after the siting. Because Jisan sewage disposal plant did not have a stench and a larger capacity and its surrounding areas were blended by commercial and residential uses, a sewage disposal plant siting had little effect on the fall in land prices unlike previous studies. The findings from this research will provide new reference data for local government and local people with conflicting views on the siting of a basic environmental facility.

This study was conducted to verify the effect of chlorine dioxide ($ClO_2$) on odor reduction at a commercial swine facility consisting of a compost ficility. Compost facility in $NH_3$ concentration was around 550 ppm and less than 78 ppm before and after the $ClO_2$ spraying, respectively, which was over 86% reduction. There was no H2S detection. $NH_3$ concentration was around 420 ppm and less than 35 ppm before and after the $ClO_2$ spraying, respectively, which was over 83% reduction. $H_2S$ concentration was around 210 ppb and less than 32 ppb before and after the $ClO_2$ spraying, respectively, which was over 85% reduction. Hence, $ClO_2$ spraying at windowless barns was compost facility decreased malodor such as $NH_3$.

In recent years, fast growing cities in Korea are showing signs of being vulnerable to more disasters as their population and facilities increase and intensify. In particular, fire is one of the most common disasters in Korea's cities, along with traffic accidents. Therefore, in this study, we analyze what type of factors affect the fire that threatens urban people. Fire data were acquired for 10 years, from 2007 to 2017, in Jinju, Korea. Spatial distribution pattern of fire occurrence in Jinju was assessed through the spatial autocorrelation analysis. First, spatial autocorrelation analysis was carried out to grasp the spatial distribution pattern of fire occurrence in Jinju city. In addition, correlation and multiple regression analysis were used to confirm spatial dependency and abnormality among factors. Based on this, OLS (Ordinary Least Square) regression analysis was performed using space weighting considering fire location and spatial location of each facility. As a result, First, LISA (Local Indicator of Spatial Association) analysis of the occurrence of fire in Jinju shows that the most central commercial area are fire department, industrial area, and residential area. Second, the OLS regression model was analyzed by applying spatial weighting, focusing on the most derived factors of multiple regression analysis, by integrating population and social variables and physical variables. As a result, the second kind of neighborhood living facility showed the highest correlation with the fire occurrence, followed by the following in the order of single house, sales facility, first type of neighborhood living facility, and number of households. The results of this study are expected to be useful for analyzing the fire occurrence factors of each facility in urban areas and establishing fire safety measures.

In commercial facilities, it is very difficult in real to promote specific products among various products because various products are displayed and sold. Therefore, in order to promote information on most display products, there is a great tendency to rely on printed matter or salesperson. So, it is focused to display advertising or promotional video based on interactive user information by utilizing the diplay used in the store, and to implement technology considering energy saving. Also it is very utilized for a specific product sold or displayed at a commercial facility to be sent to manufacturer or advertiser who wants to promote specific products and content at customer contacts. In this study, we implemented that maximized advertisement effect through the advertisement video and combination of product using transparent display. we implemented User-oriented image display technology to provide an interactive service according to whether there is a user or not. Through this study, we proposed a new direction to maximize advertising/public relations effect in various commercial facilities.
