This study aims to provide a real-time information to the driver by effectively operating the advanced safety device attached to the freight vehicle, thereby minimizing insecure behavior of the driver such as speeding, rapid acceleration, sudden braking, And improve driving habits to prevent accidents and save energy. Advanced safety equipment is a device that warns the driver that the vehicle leaves the driving lane regardless of the intention of the driver and reduces the risk of traffic accidents by mitigating or avoiding collision by detecting a frontal collision during driving.The main contents of this report are as follows: In case of installing a warning device on a lane departing vehicle (excluding a light vehicle) and a lorry or special vehicle with a total weight exceeding 3.5 tonnes, the driver must continue to operate unless the driver releases the function.In addition, when the automatic emergency braking system is installed, the structure should be such that the braking device is operated automatically after warning the driver when the risk of collision with the running or stopped vehicle in the same direction is detected in front of the driving lane.

This study conducted an empirical analysis of the effects of job characteristics on work-family conflict relation and quality of life, as well as moderating effects in accordance with operation type, by targeting 245 dietitian/cooks working for contract foodservice companies. The results of this study are as follows. First, the autonomy and feedback had negative (−) effects on work-family conflict while functional diversity had positive (+) effects on work-family conflict. Job identity and job importance had no relation with work-family conflict. Second, work-family conflict had negative (−) effects on job satisfaction, work-family relation, job support, general happiness, and job environment while having positive (+) effects on job stress. Third, in all paths except for the path with effects of work-family conflict on job stress, there were no differences between the group of shops operating 365 days and the group of shops operating 5 days a week. It would be helpful to the effective operation of human resources by emphasizing the necessity of differentiated management for companies with shops operating 365 days and shops operating 5 days a week, as well as managing employees’ job characteristic factors, work-family conflict, and even quality of life.

Recently, interest in the development of alternative water resources has been increasing rapidly due to environmental pollution and depletion of water resources. In particular, seawater desalination has been attracting the most attention as alternative water resources. As seawater desalination consumes a large amount of energy due to high operating pressure, many researches have been conducted to improve energy efficiency such as energy recovery device (ERD). Consequently, this study aims to compare the energy efficiency of RO process according to ERD of isobaric type which is applied in scientific control pilot plant process of each 100 m3/day scale based on actual RO product water. As a result, it was confirmed that efficiency, mixing rate, and permeate conductivity were different depending on the size of the apparatus even though the same principle of the ERD was applied. It is believed that this is caused by the difference in cross-sectional area of the contacted portion for pressure transfer inside the ERD. Therefore, further study is needed to confirm the optimum conditions what is applicable to the actual process considering the correlation with other factors as well as the factors obtained from the previous experiments.

Membrane filtration process is an advanced water treatment technology that has excellently removes turbidity and microorganisms. However, it is known that it has problems such as low economic efficiency and the operating stability. Therefore, this study was to evaluate on the economical feasibility and operational stability comparison of membrane and sand filtration process in Im-sil drinking water treatment plant. For the economic analysis of each process, the electricity cost and chemical consumption were compared. In the case of electric power consumption, electricity cost is 68.67KRW/㎥ for sand filtration and 79.98KRW/㎥ for membrane filtration, respectively. Therefore, membrane filtration process was about 16% higher than sand filtration process of electricity cost. While, the coagulant usage in the membrane filtration process was 43% lower than the sand filtration process. Thus, comparing the operation costs of the two processes, there is no significant difference in the operating cost of the membrane filtration process and the sand filtration process as 85.94KRW/m3 and 79.71KRW/m3 respectively (the sum of electricity and chemical cost). As a result of operating the membrane filtration process for 3 years including the winter season and the high turbidity period, the filtrated water turbidity was stable to less than 0.025 NTU irrespective of changes in the turbidity of raw water. And the CIP(Clean In Place) cycle turned out to be more than 1 year. Based on the results of this study, the membrane filtration process showed high performance of water quality, and it was also determined to have the economics and operation stability.

기념관은 특정 역사적 사건이나 인물, 시대, 현장을 기억하기 위한 곳이며, 잊고 있던 기억과 만나 현재의 자신을 생각해 볼 수 있는 공간이다. 기념관에서는 사람들이 자발적으로 추모의 경험을 할 수 있도록 특정 역사적 대상을 설명할 수 있는 기반을 마련하는 데 주력한다. 그러한 맥락에서 기념관에서의 교육기능은 더욱 중시된다. 기념관에서 이루어지는 교육은 크게 전시관을 안내하고 관람을 지원하는 교육서비스부터 대상과 주제 등에 따라 강의, 체험활동, 답사 등으로 운영되는 다양한 프로그램, 기념관이라는 물리적으로 벗어나 기념 대상의 학습기회를 제공할 수 있는 아웃리치(outreach) 프로그램으로 구분될 수 있다. 현재 대표적인 역사 교육기관으로 활성화되고 있는 독립기념관, 백범김구기념관, 경상북도독립운동기념관은 방문자 유형 및 내‧외부 환경을 고려하여 기관의 특성에 맞게 교육기능을 수행하고 있다. 이사부기념관은 해양인물 이사부를 통해 우리나라의 동해 개척과 독도수호의 역사를 알리고, 국민들의 영토의식 함양을 위해 강원도 삼척에 만들어질 공간이다. 이사부기념관이 국민이 즐겨 찾는 역사학습공간으로 성장하기 위해서는 우선 기관의 설립목적에 따라 관람객이 기억하고 학습해야 하는 목표와 내용을 명확히 정해야 한다. 더불어 이사부기념관을 방문할 관람객 유형과 수, 즉 수요를 예측하 고 이에 맞춘 이사부기념관만의 교육서비스와 프로그램을 기획할 필요가 있다. 이를 위해서는 현재 활성화되고 있는 기념관들의 현황을 참고하여 중장기적인 차원 에서 운영 전략이 마련되어야 하며 전시 및 교육시설과 전문 인력, 예산이 수반되어야 한다. 그래야만 이사부기념관이 영토 수호의식을 함양할 수 있는 대표적인 역사교육기관이자 관람객이 즐겨 찾는 에듀테인먼트(edutainment) 기관으로 자리 매김할 수 있을 것이다.

Domestic fishing villages' net profit has consistently dropped down in recently, and currently it is down to 16.4%.This paper develop and increase fishing profit as this project will decrease 20% of the operation cost and eventually vitalize the fishing villages' economy. Especially, it could be an alternative solution to the constant requests of WTO (World Trade Organization) and UN ECOSOC (UN Economic and Social Council) to stop cross subsidization of marine products. IMO (International Maritime Organization) is concerned about air pollution caused by carbon dioxide production, and it strongly suggests on decreasing carbon dioxide discharge level. This paper will help protect ocean ecology as it will not only decrease various types of oil usage but also promote alternative technology solution. Also Increase business' profit by selling ocean and other related business parts and factors. Low speed electric car applies high performance level of motor and motor control devices. Among those, about 20% is the original cost of motor and motor control devices. Therefor entering low speed electric car market, parts sales and sales will increase.
