RDF 생산 기술은 국내 실정에 맞는 제조 설비로 자체 생산할 수 있는 단계이지만, 사업장 가연성 폐기물에 대한 연료화 설비가 구축된 사례는 드물다. 본 연구에서는 사업장 가연성 폐기물을 대상으로 한 RPF(Refuse Plastic Fuel) 제조 공정의 고형연료 제조 가능성에 대해 검토하였다. 고형연료는 폐합성수지, 폐지 및 폐목재의 지역별 폐기물 발생비율 기준으로 제조되었으며, 제조된 RPF의 물리적 특성을 조사하였다. 대경(대구, 경북)지역을 기준으로 제조된 RPF의 발열량이 가장 높게 나타났으며, 폐지와 폐목재의 첨가량이 늘어날수록 발열량은 감소하였다. The level manufacturing technique for refuse derived fuel (RDF) is possible to produce them itself by a domestic process which is appropriate in Korea. However, very few facilities were used for industrial combustible waste. The objective of this research is to develop the technique for refuse plastic fuel (RPF) of industrial waste. RPFs were prepared by mixing of plastic, paper and wood based on amount of regional waste. The physical properties of the RPFs prepared were investigated. RPFs prepared at mixing ratio(plastic : paper : wood) of 87.55% : 8.15% : 4.3% show the highest lower heating values in wet-base (LHVW) and the LHVW decreases as the mixing ratio of paper and wood increases.

GNSS 수신기는 자율주행 자동차에 장착되어 항법 장치를 이루는 필수 요소이다. 하지만 의도적인 재밍 신호가 발생하였을 경우, GNSS 수신기 추정 위치 값의 성능 저하로 인해 사고 위험에 노출될 우려가 있다. 이를 방지하기 위한 연구가 필요하며, 그에 따라 재밍 발생 장치가 구비되어야 한다. 그러나 재밍에 관련한 법 조항에 따라 이를 불법으로 규정하고 있다. 본 논문에서는 법 조항을 준수하고, 주위 GNSS 센서에 영향을 주지 않는 차량 내 재밍 발생 장치를 구현한다. GNSS 알고리즘의 성능 평가를 위해 드라이빙 시뮬레이션을 활용하며, 간섭 환경에서 발생하는 자율주행 차량의 오작동 및 GNSS 센서에서 출력된 데이터 오차를 분석한다. A GNSS receiver installed in autonomous vehicles is the most essential device for its navigation. However, if an intentional jamming signal is generated, there is a risk of exposure to an accident risk due to deterioration of the GNSS sensor's performance. Research is required to prevent this, and accordingly, a jamming generating device must be provided. However, according to the provisions of the law related to jamming, this is illegal. In this paper, we implement an in-vehicle jamming device that complies with the provisions of the law and does not affect the surrounding GNSS sensors. Driving simulation is used to evaluate the performance of the GNSS algorithm, and the malfunction of autonomous vehicles occurring in the interference environment and data errors output from the GNSS sensor are analyzed.

Objectives The purpose of this study is to investigate the effect of Jihwangbaekho-tang on chest discomfort of unknown cause in a 52-year-old male patient diagnosed with Soyangin. Methods Patient had chest discomfort. But, the cause of this symptom was not identified by various cardiac examinations. The patient was treated with Soyangin Jihwangbaekho-tang for 2 weeks on the basis of Sasang Constitutional Medicine and the symptoms were evaluated by GAS(Global Assessment Scale). Results After using Jihwangbaekho-tang, GAS score has been decreased from 7 to 3. Conclusions This case study suggests that chest discomfort, whose cause is unknown, can be treated when using Sasang Constitutional Medicine.

폐기물을 이용한 고형연료의 제조는 온실가스 저감과 대체연료로써의 이윤 창출 목적으로 많은 연구가 진행 되었고, 이로 인해 상용화가 이루어 질 정도로 기술적인 발전을 거듭 하였다. 하지만, 단일폐기물에 대한 고형연료의 제조는 성분 변화가 별로 없지만 여러 가지 폐기물을 혼합하여 고형연료를 만들 경우에는 주의가 필요하다. 본 연구 에서는 다양한 폐기물을 이용하여 제조한 고형연료의 특성 분석을 하였다. 특성분석 결과 성형 전 폐기물과 성형 후 고형연료는 발열량 차이가 크게 나타났으며, 그 원인으로는 폐기물의 성상, 수분, 혼합정도에 기인되었다. 균일 혼합 후 폐기물 고형연료는 발열량이 6,000kcal/kg을 넘었다. The manufacturing of the solid fuel using wastes has been studied on the purpose of the reduction of green house gases and the profit-making as alternative fuel, and thus, it has become as technically improved as to be used as business. However, the production of solid fuel with multi-wastes combination needs a caution while the solid fuel with one-waste has not a significant component change. This study analyzes the solid fuel components through the practical plant experiment to the various wastes. The resulted data shows a different pattern than the theoretical one in the component analysis, and it can be concluded that the adequate uniform mixing has a great influence on the manufacturing of the solid soil.

The demand for red ginseng (RS) products made by processing ginseng has increased with an interest for health of consumer, and hence it is required to evaluate the safety for residual pesticides in the RS products. However, there are no authorized analysis methods of pesticides for RS products. In this study, a multiresidue analysis method of 43 pesticides in RS products such as pure extract and concentrated extract was developed using a liquid chromatography-tandem mass spectrometry. Small amounts of sample were used in the analysis, and the pesticides were extracted with acetonitrile. The clean-up of samples was conducted using dispersive solid phase extraction with the primary secondary amine and anhydrous magnesium sulfate. The analytical method developed in this study was amenable to 37 (pure extract) and 34 (concentrated extract) of 43 tested pesticides. Using the developed method, the limits of quantification of the amenable pesticides in the RS products were between 3 and 70 ng mL-1, and the linearities of their matrix-matched standard calibration curves were acceptable with high correlation coefficients of >0.98. In addition, recoveries of amenable pesticides in the RS products ranged from 70.0 to 118.0%, with relative standard deviations of 0.5∼19.5%. Therefore, the analytical method developed in this study could be used as an efficient analysis method of pesticides for pure extract and concentrated extract products of RS.

In this paper, single phase boost converter with low current harmonic components and high power factor are proposed. A single-phase half-bridge rectifier based on a neutral point switch clamped scheme is proposed to draw a nearly unity power factor and regulate the DC link voltage. Three power switches are employed in the proposed rectifier. This rectifier is controlled to generate a bipolar or unipolar PWM voltage waveform on the AC side. The proposed converter is implemented by a digital signal processor.
