  • This paper deals with a newly developed direction indicator system of a car which displays left turn and U- turn signal differently, so that the following driver can identify the Intent of the next car ahead easily. In general, when a car want to change its direction, the driver move the blinker lever below the steering wheel up or down. However, as the left turn and U-turn signal are the same, there always be the risk of rear-end collision by misinterpreting U-turn signal as left turn signal. In this paper, a new direction indicator system which differentiates left turn and U-turn signal is developed. The left turn signal is the same as before, but when a driver want to U-turn, an additional U-turn signal blinks at the rear of the car. By identifying the direction signals clearly, the developed system is expected to alleviate the risk of car accident.

  • It is important to improve the energy performance in the industrial sector, and therefore most of the manufacturing companies need the energy performance indicators to identify the target and to verify the energy savings. However, the conventional energy performance indicators such as the total energy consumption and the energy intensity are not proper to use. The reason is that they do not consider adequate relevant variables including productions in the boundary of the manufacturing companies. Therefore, the study provides the advanced energy performance indicator using by the linear regression model according to each energy source to manage the target and to verify the energy performance properly.

  • Korean distant water trawl fisheries were sector of most important distant water fisheries with tuna long liner fisheries during the development age in Korea. Nevertheless Korean distant water trawl fisheries have suffered from catches and Income problem. It was caused to the strengthen regulation of costal countries, the rapid liberalization trend of trade on the fishing products and the shortage of cheap manpower, etc. In this situation, Korean government is inclined to convert big adjacent trawl fisheries of distant water trawl fisheries for structure adjustment In domestic fisheries. that is analyzed to incorrect method because the efficiency of management indicator in adjacent trawl fisheries was bad than distant water trawl fisheries. Then this policy of Korean government needs to convert anything else. Also it was compared with one of Japan to the efficiency of management indicator of Korean distant trawl fisheries. The result of analysis, Korea was better than Japan in some factor, especially labor cost Then if Korean government will put weighted policy on this viewpoint, Korean distant water trawl can more grow.

  • Many studies have been conducted to develop new technologies for arsenic removal and to reveal the levels of arsenic and other chemicals in rivers, lakes and ground waters. However, there are few studies dealing with such compounds in the total water system of the city, and the way of management of these compounds in the water system. Because the occurrence of these hazardous compounds, which are geological origins, is almost impossible to control, it is very important to manage these compounds in the water system. In this research, it was revealed that the risk of arsenic in the water treatment system of S city in Japan. As a results, the parameters such as Q in river and E260 in drinking water treatment plant is proposed as a new indicator with simple and rapid method for controling arsenic level.

  • The aim of this study is to develop suitability site indicator of urban-rural return to fishing and to analysis priority of the indicators. The study is based on literature review, expert survey and AHP(Analytic Hierarchy Process) methods. This study found 5 factors(natural environment, acceptance environment, social overhead capital, economy, fishing environment) and 21 detail variables. as a result of AHP, fisheries resources, acquisition convenience of fishing license, income(except fishing), attitude of local resident, one-person household income, high income fishing were showed high priority. This result indicate that economic foundation is most important factor for suitable site of the returning.

  • Objectives The aim of study was to suggest diagnostic indicator according to Exterior-Interior disease for the Sasang Constitution based on original symptom. Methods We investigated the literature(『Dongeuisusebowon sinchukbon』) and another study(Clinical Practice Guideline for Disease of Sasang Constitutional Medicine: Diagnosis and Algorithm). As a result, we developed diagnostic indicator of original symptom for Exterior-Interior disease in Sasang Constitutional Medicine. Results and Conclusions Diagnosis of Exterior-Interior disease in Sasang Constitution was decided by heat and cold of original symptom. Detailed indicators of diagnosis in Exterior-Interior disease were heat/cold sensitivity, the degree of sweating, the amount of drinking water, thirst, face color and somatalgia.

  • The purpose of this study is to develop the performance evaluation indicator of information security training program for developing the next generation of top security leaders. Through literature review and focus group interview, we derived the performance areas and indicators based on the logic model. We conducted AHP(Analytic Hierarchy Process) questionnaire to calculate the weight of the derived indicators, and developed the performance indicator based on the survey results. Performance indicators were composed of 18 indicators in four main categories.

  • There is an urgent need to identify more reliable indicator systems for human pathogenic viruses in water reuse practice. In this study, we determined the response of different bacteriophages representing various bacteriophage groups to different ultraviolet (UV) technologies in real wastewater in order to identify more reliable bacteriophage indicator systems for UV disinfection in wastewater. Bacteriophage ${\varphi}X174$ PRD1, and MS2 in two different real wastewaters were irradiated with several doses of both low pressure (LP) and medium pressure (MP) UV irradiation through bench-scale UV collimated apparatus. The inactivation rate of ${\varphi}X174$ by both LP and MP UV was rapid and reached ${\sim}4{\log}_{10}$ within a UV dose of $20mJ/cm^2$. However, the inactivation rates of bacteriophage PRD1 and MS2 were much slower than the one for ${\varphi}X174$ and only ${\sim}1{\log}_{10}$ inactivation was achieved by the same UV dose of $20mJ/cm^2$. Overall, the results of this study suggest that bacteriophage MS2 could be a reliable indicator for human pathogenic viruses for both LP and MP UV disinfection in wastewater treatment processes and water reuse practice.
