PURPOSES : The objective of this study is to evaluate the effectiveness of spraying dust suppressants in relation to the condition of road pavement in South Korea and to develop an optimal management method by continuously measuring re-suspended dust concentrations using a vehicle-based measurement. METHODS : Indoor experiments were conducted to select suppressants suitable for local conditions to reduce reducing road dust, which were identified through literature review. Data collection followed the evaluation method by selecting a section sprayed with dust suppressants and a non-sprayed section within the service road. RESULTS : The BPT experiment is designed to ensure the skid resistance of the road when dust suppressants are sprayed on the road. The Environmental toxic tests for PM10, HCHO, and TVOC all met the daily indoor air quality standards recommended in Korea for determining stability. Comparison of PM10 contents before and after spraying of the test road with dust suppressants and the non-sprayed section, it was confirmed that the dust suspended by the external environment may be reduced, but the amount of dust remaining on the road may increase. After 4 hours, when the water had evaporated, the dust suppressants remained effective and lasted for two-days. CONCLUSIONS : The concentration of fine dust in South Korea varies with the average duration of highly concentrated fine dust being 26.5 h nationwide, 20.5 h in the Seoul metropolitan area, and 25.1 h in Gyeonggi-province, suggesting a duration of one to two days. Thus, the fine dust problem can be solved by using dust suppressants.

본 논문은 교회개척자의 핵심역량 및 유용한 자산을 파악하기 위하여 전문가 델파이 조사방법을 활용하여 개척자의 주요역량을 파악 하고 역량 군에 따른 세부항목을 설정하여 개척자의 자산과 역량을 세분화하고 분석하는 작업으로 이루어졌다. 한국교회의 개척현실을 살펴볼 때 다양한 관점에서 개척자에 대한 연구의 필요성이 제기되기에 이 연구를 통해 개척교회 목회자의 기본 자질과 역량을 이해하고 이에 대한 평가항목을 설정해 궁극적으로 개척 목회자의 역할을 이해하는데 기초자료를 제공할 수 있으리라 사료된다. 교회개척자 역량 평가도구 개발에 전문가 델파이 조사 방식을 활용함으로써 외적 준거나 합리적인 공식이 마련되지 않은 교회개척자에게 요구되는 역량과 이를 평가할 수 있는 의미 있는 평가도구를 개발하는 점을 목표로 하였다. 이러한 평가를 통해 교회 개척 지원자가 전문가들이 제시하는 역량과 세부항목 을 구비하고 있는지 평가할 수 있는 계기를 마련하고자 하였으며 한국교 회가 가지고 있는 제한된 선교자원과 교회개척 지원 능력이 우선순위에 따라 꼭 필요한 곳에 배분되어 교회개척 사명을 효율적으로 감당되는 일을 목표로 하였다.

Recently, wideband acoustic technology has been introduced and started to be used in fisheries acoustic surveys in various waters worldwide. Wideband acoustic data provides high vertical resolution, high signal-to-noise ratio and continuous frequency characteristics over a wide frequency range for species identification. In this study, the main characteristics of wideband acoustic systems were elaborated, and a general methodology for wideband acoustic data analysis was presented using data collected in frequency modulation mode for the first time in Republic of Korea. In particular, this study described the data recording method using the mission planner of the wideband autonomous acoustic system, wideband acoustic data signal processing, calibration and the wideband frequency response graph. Since wideband acoustic systems are currently installed on many training and research vessels, it is expected that the results of this study can be used as basic knowledge for fisheries acoustic research using the state-of-the-art system.

As coffee consumption increases, coffee extraction's by-products increase. Research on coffee by-product recycling is fundamental as social costs and environmental problems arise from the course of coffee processing, estimated to be 270,000 tons per year. This study attempted to confirm the possibility of an eco-friendly food packaging material by solvating cellulose from spent coffee grounds. For cellulose solubility, delignification and TEMPO (2,2,6,6- tetramethylpiperidin-1-oxyl) oxidation treatment were performed. An optimal plasticizer (glycerol) and a crosslinking agent (cinnamaldehyde) were added to the film-forming solution for film manufacturing, while physical treatment (high-pressure treatment, 276 MPa, 10 times) was done to improve physical properties. Then, the film was dried by a solution-casting method. Physical properties of food packaging materials such as tensile strength, elongation, water-solubility, thickness, and chromaticity were measured. In particular, the film to which 1.5% glycerol was added showed the highest value among the physical properties of the dried film. These results indicate that TEMPOSCG films have potential as eco-friendly food packaging materials in the food industry.

To solve the pathological problems of the musculoskeletal system based on evidence, a sophisticated analysis of human motion is required. Traditional optical motion capture systems with high validity and reliability have been utilized in clinical practice for a long time. However, expensive equipment and professional technicians are required to construct optical motion capture systems, hence they are used at a limited capacity in clinical settings despite their advantages. The development of information technology has overcome the existing limit and paved the way for constructing a motion capture system that can be operated at a low cost. Recently, with the development of computer vision-based technology and optical markerless tracking technology, webcam-based 3D human motion analysis has become possible, in which the intuitive interface increases the user-friendliness to non-specialists. In addition, unlike conventional optical motion capture, with this approach, it is possible to analyze motions of multiple people at simultaneously. In a non-optical motion capture system, an inertial measurement unit is typically used, which is not significantly different from a conventional optical motion capture system in terms of its validity and reliability. With the development of markerless technology and advent of non-optical motion capture systems, it is a great advantage that human motion analysis is no longer limited to laboratories.
