김관덕 空軍士官學校 1998 論文集 Vol.42 No.-
THIS THESIS IS CONCERNED WITH THE DESIGN OF RESIDUAL CONTROL CHARTS WITH RUNS RULES FOR AUTOCORRELATED DATA WHICH ARE FREQUENTLY TAKEN FROM CONTINUOUS FLOW PROCESSES AND LEADS TO INCREASE THE NUMBER OF FALSE ALARMS WHEN TRA-DITIONAL CONTROL CHARTS ARE APPLIED IN PROCESS MONITORING. THE ANALYSIS OF RE-SIDUAL'S BEHAVIOR MAKES CLEAR THAT SINCE THE EXPECTATION OF A RESIDUAL AFTER THE SHIFT OCCURS IS A DECREASING FUNCTION OF THE TIME AFTER THE SHIFT, THE PROBABILITY OF A SIGNAL BY A RESIDUAL CONTROL CHART CONTINUALLY DECREASES OVER TIME AS THE FORECAST ADAPTS TO THE SHIFT. THERE ARE PROPOSED RUNS RULES DESIGNED TO DETECT THE NONRANDOM RESIDUAL'S BEHAVIOR AS QUICKLY AS POSSIBLE. SIMULATION STUDIES SHOW THAT THE APPROPRIATE RUNS RULES EXIST ACCORDING THE RESIDUAL'S BEHAVIOR THAN TIME-SERIES MODES.

고품질 우량인삼 생산을 위한 해가림자재별 인삼의 생육 상황과 해가림 아래의 미기상 변화를 조사하였고, 각각의 해가림자재에서 생산된 수삼의 유효성분들을 조사 분석한 결과, 6~8월까지의 해가림자재별로 온도는 차광지>차광판> 차광지 순이었고, 투광량도 차광지가 8월에 381.7 μmol/s/m2 로 인삼포내 온도가 가장 높은 원인이었다. 2~3년 인삼의 지상부 생육은 차광망>차광판>차광지 순이었으며, 4년근은 차광판=차광지>차광망 순으로 좋았다. 4년근 인삼의 진세 노사이드 총함량은 차광판>차광지>차광망 순으로 많았으 며, 수삼의 색도는 차광망>차광판>차광지 순으로 높았다 This research investigated growth of ginseng regard to sunshade materials and micro metrological phenomena under the sunshade material to product high quality ginseng. Followings are results of investigation of active ingredient from raw ginseng producted under the sunshade materials. The highest temperature under the sunshade material from June to August was measured from a Three-layered blue and one-layered black polyethylene net (TBOBFN) followed by a aluminium-coated polyethylene sheet (ACPS) and blue polyethylene sheet (BPS). The highest light penetration of 381.7μmol/s/m2 was obtained from the BPS at August, also the temperature was highest at the ginseng field. Growth of above ground part of 2~3 year old ginseng under the ACPS was the highest, followed by the ACPS and the BPS. In case of 4 year old ginseng, the ACPS and the BPS was the same, followed by the TBOBPN. Root length and diameter of 2~3 year old ginseng showed difference among treatments, but 4 year old ginseng was not showed difference. Meanwhile, the highest amount of root of 4 year old ginseng of 896 g/m2 was obtained from ACPS. The total amount of ginsenocide of 4 year old ginseng under the ACPS was highest, followed by the BPS and the TBOBPN. Chromaticity of ginseng root under the TBOBPN was highest, followed by the ACPS and the BPS.

This study investigated ginseng growth andginsenoside contents after control a reserved ginseng cultivationland using various green manure crops for stable ginsengcultivation. Followings are results obtained from this research. After cultivate the green manure crops, microbial flora insoil was diversified, organic matter and total-N contentincreased, but salt content decreased. The highest outputobtained from the wheat cultivated area among variousgreen manure corps. Growth of shoot and root of two yearsold ginseng increased significantly at the green manure cropcultivated area. Specially, the wheat cultivated area was themost effective in growth. Also, the rate of the leaf discolorationat the aerial part and the rusty root at the root was the leastat the wheat cultivation area. Meanwhile, the ginsenosidecontent was the most at the wheat cultivation area. Thus,the reserved ginseng cultivation land could be managed bycultivating wheat for effective ginseng growth

대수층에 이산화탄소를 주입하여 저장하는 것은 대기 중 이산화탄소 농도를 저감하는데 중요한 역할을 한다. 하지만 이산화탄소 주입 시 대수층의 압력증가로 단층 재활성화가 발생할 수 있다. 이러한 문제를 예방하기 위해 이산화탄소 주입에 따른 대수층 압력변화를 분석하는 것이 필요하다. 본 연구에서는 포항영일만 지질모델의 이산화탄소 주입정에서 450 m 떨어진 EF1 단층과 530 m 떨어진 EF2 단층에 대해 안정성 분석을 수행하였다. 약 2년 동안 이산화탄소의 주입과 중단을 반복하는 두 가지 시나리오에서 대수층 압력변화가 단층에 영향을 주는지 일일주입량(20 tons, 40 tons, 100 tons)에 따라 분석하였다. 또한 각 일일주입량 별로 계획 주입량과 예측 주입량을 비교하였다. 이산화탄소 일일주입량이 20 tons인 경우 단층에서의 최대압력이 단충 재활성압의 65% 수준으로 단층의 재활성화 가능성이 낮았다. 일일주입량이 40 tons과 100 tons으로 증가해도 단층에서의 최대 압력이 단층 재활성압의 각각 71%와 80% 정도이다. 또한 일일주입량이 20 tons인 경우와 40 tons인 경우 계획 주입량과 예측 주입량이 거의 일치하였지만 100 tons인 경우 주입정의 공저압력 허용한계로 인해 시뮬레이션 예측 주입량이 계획 주입량에 미치지 못하였다. It is imperative to inject carbon dioxide(CO<sub>2</sub>) into an aquifer for alleviating the emission of CO<sub>2</sub>. However, faults in the aquifer can be reactivated due to pressure increasement. Analyses of pressure change of the aquifer is necessary to prevent the fault reactivation. In this research, we assess the stability of an aquifer in Pohang Yeongil bay by investigating the pressure variation of faults EF1 and EF2. Two scenarios, which repeat CO<sub>2</sub> injection and suspension during two years, are simulated. Each scenario includes cases of injection rates of 20, 40, and 100 tons/day. In addition, we analyze planned and predicted injection rates for each case. In case of 20 tons/day, the maximum pressure of faults is 65% of the reactivation pressure. Even if daily injection rates are increased to 40 and 100 tons/day, the maximum pressures are 71% and 80% of the reactivation pressures, respectively. For 20 and 40 tons/day cases, planned injection rates almost accord with predicted injection rates during whole simulation period. On the other hand, predicted injection rates are smaller than planned injection rates for the 100 tons/day case due to bottom-hole pressure limit of the injection well.
