본 연구에서는 고령자의 자가 점유율이 높다는 점에 착안하여 주거공 간에서 사회관계망을 확대할 수 있는 방안에 대해 연구한다. 해외 사례 분석을 통해 IT를 기본으로하는 에이징테크(Aging-Tech) 산업을 활용하 여 고령자 생활편의를 제공하고 사회관계망의 확대를 통해 고령자의 삶 의 질을 향상할 수 있는 세 가지 방안을 제안하였다. 첫째, 스마트홈으로 고령자의 안전한 가정생활 실현 및 건강관리 보조가 연계된 방향으로 개발되어야 한다. 둘째, 양방향 TV 서비스의 지원이 필요하다. 이를 통해 고령자가 쉽게 사회적 관계 네트워크를 형성할 수 있도록 해야 한다. 셋째, 고령자의 신체노화로 인해 기기에 대한 활용도가 떨어진다는 점을 고려해 음성형 지원 프로그램 개발도 필요하다. 포스트코로나 이후 집단 돌봄에 대한 근본적 해결 요구와 가정 중심 서비스에 대한 관심이 더욱 더 증가할 것으로 예상되기 때문이다. 따라서 고령자의 안전한 생활을 영위하고 사회적 네트워크 형성을 통한 삶의 질을 높일 수 있는 방향으로 에이징테크(Aging-Tech) 산업을 활용하여 고령친화산업을 발전시켜야 한다.

배스(Micropterus salmoides)는 수생태계에서 최상위단계에 위치하는 생태계교란 어종으로 심각한 담수생태계의 불균형을 초래하고 있다. 배스의 퇴치 및 관리를 위한 다양한 시도를 하고 있지만 효과적인 방안은 없는 상황이므로 배스의 고유한 특성에 기반한 개체군 감소의 효율성을 극대화할 수 있는 방식을 모색하였다. 본 연구에서는 배스의 Transcriptom 분석으로 Unigene contigs는 182,887개, 그리고 정자-난자 인식 단백질인 IZUMO1과 Zona pellucida sperm-binding protein의 유전자에서 CRISPR/Cas9 system을 적용할 최종 Target sequence는 12종을 산출하였다. 각 Target sequence를 인식할 수 있는 12종의 sgRNA를 합성한 후 후속 연구에 사용할 12종의 Cas9-sgRNA ribonucleoprotein (RNP) complex를 제작하였다. 본 연구에서는 차세대염기서열 분석법으로 정자-난자 인식 단백질을 암호화하는 유전자를 탐색하였고, CRISPR/Cas9 system으로 유전자를 편집하여 번식행동은 하지만 수정란을 형성하지 못하는 생식세포를 생산하는 불임개체를 유도하기 위한 조성물 개발 과정을 확립하였다. 그리고 배스와 동일한 수계에 있는 고유 생물종의 서식에는 영향을 미치지 않는 생태교란종 관리 방안으로서의 유용성을 검증하기 위한 후속 연구의 귀중한 기초 자료를 확보하는데 기여했다고 판단된다.

In this study, actual odor conditions were investigated in restaurants, livestock facilities, and major odor discharge facilities around daily life, and an odor modeling program was performed to find ways to improve odors in odor discharge facilities. The odor modeling results of restaurants around daily life showed that the complex odor concentration of large restaurants, which are close to residential areas, is higher than the acceptable complex odor standard at the receiving point. It was judged that a plan to increase the height of the restaurant odor outlets and a plan to reduce the amount of odor discharge was necessary. As a result of modeling the life odor of livestock housing facilities, when the distance from the housing facility is far away, the actual emission concentration is much lower than the acceptable emission concentration at the receiving point. It was judged that such facilities need to be reviewed for ways to reduce the emission of odorous substances, such as sealing the livestock housing facilities or improving the livestock environment. The main odor emission business sites that show complex odor concentration as 1,000 times or greater than the outlet odor emission standard were businesses associated with surfactant preparation, compounded feed manufacturing, textile dyeing processing, and waste disposal. Due to the separation distance and high exhaust gas flow rate, it was found that odor reduction measures are necessary. In this study, it was possible to present the allowable odor emission concentration at the discharge facilities such as restaurants, livestock houses, and industrial emission facilities by performing the process of verifying the discharge concentration of the actual discharge facility and the result of living odor modeling. It is believed that suitable odor management and prevention facilities can be operated.

In this paper, the heat transfer performance of nanofluids is predicted by numerical analysis methods. The nanoparticles used in this study is SiO2, with concentrations of 1, 2, 3vol.%, and the base fluid is water. Reynolds number of nanofluids ranges from 10,000 to 50,000. A numerical study on the heat transfer characteristics of nanofluid was conducted using a single-phase model. The temperature of the fluid entering from the inlet of the tube is 293.15K. A constant heat flux of 31,650W/m2 was applied at the wall, and the thickness of the wall was ignored. Heat transfer coefficients, thermal conductivity and Nusselt number were selected as indicators for comparing heat transfer performance of nanofluids. As the nanofluid concentration increases, the temperature and velocity distribution by the cross section of the coil tube and straight tube increased. As the Reynolds number increases, temperature difference between inner direction and outer direction reduced in coil tube. For straight tube, the temperature difference between the wall and the center of the tube also decreased.

In this study, real-time monitoring of air quality using a real-time mobile monitoring system was conducted to identify the emission characteristics and current status of air pollutants and odorous substances that are mainly generated in domestic dyeing industrial areas and to trace the pollutant sources. The concentration of toluene in the industrial area was detected up to 926.4 ppb, which was 3 to 4 times higher than that of other industrial areas. The concentration of methylethylketone was 124.7 ppb and the concentration of dichloromethane was 129.5 ppb. Acrolein concentration was highest at E point at 521.6 ppb, methanol concentration was highest at D point at 208.8 ppb, and acetone concentration was highest at M and N points at 549.3 ppb. The most frequently detected concentration of pollutants in the air quality monitoring results in the industrial area was, in descending order, toluene > methanol > acrolein > dichloromethane > acetone, which was similar to the chemical emissions used in the industrial area by the Pollutant Release and Transfer Register data. The concentration of odorous substances measured in real time was compared with the concentration of minimum detection, and the concentration of hydrogen sulfide was about 10 times higher than the concentration of minimum detection at A point, which was judged to be the main odorous cause of A point. In the future, if the real-time mobile measurement system is constructed to automatically connect wind direction/wind speed, PRTR (Pollutant Release and Transfer Register) data and SEMS (Stack Emission Management System) data, etc., it was judged that more accurate monitoring could be performed.

In this study, the grid field olfactory odor method was supplemented to the domestic situation in the surrounding areas of a domestic science industrial complex. The actual condition of the occurrence of odor frequency in the field was then investigated over the first period of late spring to summer and the second period of autumn in 2017. The frequency of odor occurrence in the area around the science industrial complex was increased as odor discharge facilities in the nearby area were concentrated. The odor occurrence frequency of the total period was 0.09~0.28, that of the first period was 0.08~0.32, and that of the second period was 0.05~0.25. The odor occurrence frequency in summer was higher than in autumn. The frequency by which the measurement of odor occurrence by smell type was most dominant was mainly smell of chemicals, plastics, and livestock houses during the first period, and the smell of chemicals, burning gases, and plastics during the second period. And the frequency of each smell type was judged to be different according to season. The odor occurrence frequency was measured as higher than 0.15, which is the standard of Germany's odor frequency in an industrial area, and it was judged that measures for odor management in the region were necessary. Since most of the odor discharge facilities are non-continuous systems and the odor generation frequency is more important than the concentration of the minimum detection concentration, it was judged that the German grid method can reflect the odor occurrence characteristics of the odor complaints or receptors for a certain period of time compared to the domestic measurement method. In the future, it was judged that the field olfactory odor method would be able to replace the evaluation method of odor assessment in Korea with the survey method of odor assessment under actual conditions in areas where it is difficult to access the odor discharge source or the receptor where odor complaints occur.
