본고는 林養正(1716-1777)의 문집인 『수분와집』을 텍스트로 하여, 그의 생애와 가학을 계승하고 실천한 양상을 살피는 데 목적이 있다. 『守分窩集』은 별도의 목차 없이 그의 지향을 밝힌 문장인 ｢守分窩 序｣와 관련 기록 부분, 시편과 간찰을 모아놓은 부분, 家狀 관련 부분 등의 세 부분으로 구성되어 있다. 임양정은 남명학파의 학자였던 임진부(1586-1658)의 후손으로, 三嘉 지역의 학풍을 이끌어나가는 지역 명문가 출신이다. 어린 나이에 부친과 조부를 여의었으나 평생 충과 효를 실천하는 삶을 살았고, 가학 을 잇는 것을 본연의 임무로 받아들였다. 이는 성현이 남긴 文義를 명확히 이해하는 것으로, 이를 후학에게 자신이 터득한 문의를 정확히 전수 하는 방식으로 실현되었다. 아울러 가학의 전수는 임진부의『禮略』을 실천하여 誠禮의 정신을 체득하는 것으로 실현되었다. 이를 실질적으로 적용시켜 선조의 가훈을 誠孝와 公正이라는 정신으로 확립시켰다. 임양정의『수분와집』은 남명학파의 한 지파인 임곡 임진부의 후손이 향촌의 명문가로 자리 잡으면서 선조의 가훈을 어떻게 현실에서 구현시켰고 윤리규범으로 작용하였는가 보여주는 귀중한 자료라 할 수 있다.

본 연구에서는 Cosmic-ray 토양수분량 관측시스템 구축 시 필요한 검증 네트워크 설계 기법 개발에 목적을 두고 유전율식(dielectric constant) 장비인 Frequency Domain Reflectometry (FDR)와 연계하여 Cosmic-ray 검증시스템을 구축·운영하였다. Cosmic-ray 검증시스템 평가에 필요한 시범지역은 기존 계측 장비와의 연계성과 다양한 수문자료의 활용성을 고려하여 설마천 유역에 구축하였다. 시범지역은 Cosmic-ray 장비와 FDR 센서(10개소)로 구축하였으며 2018년 7월부터 현재까지 운영되고 있다. 본 연구에서는 검증시스템의 신뢰도를 높이기 위해 코어법(soil core sampling method)을 통해 산출한 용적수분함량(volumetric water content)을 유전율식 장비와 정기적으로 검증하였다. 연구기간 중 수행한 코어법과 FDR 센서를 검증한 결과, 두 자료의 통계량이 bias=-0.03 m3/m3과 RMSE=0.03 m3/m3의 유의한 값을 보였다. 또한 연구기간 동안 FDR 센서의 시계열 특성은 모든 강우에 정상적으로 반응하였다. 그러나 일부 지점에서는 낙엽 및 캐노피의 차단과 상부사면의 유출 등으로 인해 상이한 특성을 보였다. Cosmic-ray 영향원(influence line) 내 FDR 센서의 대표성 분석은 시간 안정성 해석법(temporal stability analysis, TSA)을 이용하여 토심별(10 cm, 20 cm, 30 cm, 40 cm)로 분석하였다. 10개소에 대한 토심별 토양 수분량의 대표성을 TSA로 분석한 결과, 토심 10 cm에서는 FDR 5, 토심 20 cm에서는 FDR 8, 토심 30 cm에서는 FDR 2, 토심 40 cm에서는 FDR 1에서 가장 우수한 대표 특성을 보였다. 본 연구의 시범지역 운영 기간이 짧다는 한계는 있지만 지금까지의 분석 결과를 토대로 하여 볼 때, Cosmic-ray 관측시스템 구축 시에는 검증 장비로는 유전율식을 활용하고, Cosmic-ray 영향원 내 토양수분량의 대표성 분석은 TSA 방법으로 수행하는 것이 바람직할 것으로 판단된다.

These finding could be used to increase high germination rate, is required to proper irrigation. We will need to proper moisture content to increase high germination rate not only bed soil but also soil.

Background : There are studies on the planting distance, sowing periods, and over wintering method of Saururus chinesis, but lesson the necessary soil moisture content for rhizome growth. This study examines the effects of soil moisture content on the growth of Saururus chinesis. Method and Results : The radicles of Saururus chinesis were harvested in the beginning of March and cut into three joints. The planting densities were determined as 40 ㎝ × 10 ㎝, 40 ㎝ × 20 ㎝ and 40 ㎝ × 30 ㎝, and the soil moisture content was adjusted through continuous flooding treatment, wetting (0 ~ -10 kPa), and field moisture capacity (-20 ~ -50 kPa). As a result of investigating the ground growth of Saururus chinesis, the growth through continuous flooding was best with the planting distance of 40 ㎝ × 20 ㎝ that yielded a plant height of 7.4 ㎝, stem diameter of 5.2 ㎜, and leaf number of 5.5. The growth through field capacity (-20 ~ -50 kPa) was poorest at the planting distance of 40 ㎝ ×10 ㎝. The transpiration rate, indicating the breathing of leaves, was highest at 1.4 s ㎝-1 through continuous flooding at 40 ㎝ × 30 ㎝, and decreased to 0.5 s ㎝-1 with the field capacity of (-20 ~ -50 kPa) 40 ㎝ × 20 ㎝. The investigation on the leaves showed that the leaf weight was heaviest at 23.1 g/plant through continuous flooding of 40 ㎝ × 30 ㎝ that also showed a wider leaf area and rich chlorophyll. At continuous flooding of 40 × 10 ㎝, the leaf weight was as light as 9.5 g/plant, showing no consistency among treatments. The investigation on the underground growth showed the best results through continuous flooding with a planting distance of 40 × 10 ㎝ where the root length was 50.7 ㎝, root diameter 6.7 ㎜, and fresh root weight of 45.3 g/plant, which decreased to 24.4 g/plant with field capacity (-20 ~ -50 kPa). The investigation on the polyphenol content as a functional component showed the richest content in the leaf of the plant at 752.5 ㎎/100g through continuous flooding, and lowest at 661.0 ㎎/100g with field capacity. With the field capacity (-20 ~ -50 kPa) it was the highest at 262.0 ㎎/100g. Conclusion : It was the most advantageous for mass Saururus chinensis radical production with continuous flooding treatment for soil moisture and a planting distance of 40 × 10 ㎝.

A comprehensive water budget analysis considering the water consumed for landfill gas formation was performed for Sudokwon Landfill Site 2 (LS2) from October 2000 through December 2016. The weighted average mole ratios of carbon (C), hydrogen (H), and oxygen (O) of the total disposed waste were 30.4%, 48.8%, and 20.8% respectively. The total emitted H and O as CO2 and CH4 from landfill gas was 2,812×103 Mg, of which 28.6% (803×103 Mg) was supplied from water. The total emitted water quantity consisted of landfill gas at 8.4%, leachate at 90.2%, and vapor in landfill gas at 1.4%. The total supplied water quantity to LS2 was 22.0×106 Mg, and the quantity supplied from water included in disposed waste was 62.9%. Considering the supplied and emitted water quantity, the retained quantity in LS2 was estimated to be 12×106 Mg, and the emitted and retained quantities were 43.3% and 56.7%, respectively. Considering the retained quantity, the water content in LS2 was estimated to be 26.0%, far below the optimum level for landfill site stabilization.

Vertical farming systems offer many advantages in urban spaces. They have also been proposed as an engineering solution to increase the productivity per unit area of cultivated land by extending crop production in the vertical dimension. However, soil water retention is a major constraint affecting the plant environment. This study analyzed the effects of growth environment of Tropaeolum majus and Fragaria spp., on the vertical farming system, by using four different types of cover material types including sphagnum moss (Control), a shading net (S.N.), multi-layered fabric (M.L.F.), and non-woven fabric (N.W.F.). The volumetric soil moisture contents and plant characteristics were investigated from May to September 2014. Plant materials were individually cultivated in hanging baskets measuring 30×17×17 cm, filled with a mixture of soil and perlite, and placed at 1.5m height. Each treatment was performed in quadruplicate and consisted of five plants, amounting to a total of 20 plants. The analysis indicated that different covers were associated with multiple functions and soil water retention improvements may have a positive impact on the vertical farming system. The difference in soil water retention increased in the following order: M.L.F. > Control > N.W.F. > S.N.. Furthermore, the differences in plant height and survival rate increased in the following order: M.L.F. > Control > N.W.F. > S.N. Therefore, M.L.F yielded satisfactory good response for the vertical farming system of cover materials. Our results clearly demonstrate that vertical spaces represent an attractive alternative to urban farming and suggest that further increases in yield may be achieved via different cover materials in vertical farming using hanging baskets.

유기성폐자원의 바이오가스화는 혐기소화를 통한 메탄가스(CH4)를 생산하는 시설로 현 상황에 대응하는 방안으로 15년도 기준 전국 61 개소의 하수처리장에서 하수슬러지 소화시설을 운영 중에 있다. 생산된 바이오가스는 스팀보일러를 가동하거나 발전기를 가동하여 전기를 생산하게 된다. 최초 혐기소화조에서 생산된 바이오가스는 유입된 폐기물에 따라 메탄함량 약 55~70%이며, 황화수소(H2S) 2,500~5,000ppm, 상대습도 약 90%를 나타난다. 바이오가스를 전처리 없이 바로 사용하게 되면 황화수소가 수분과 결합하여 황산을 생산하게 된다. 황산은 기계적 마찰이 많은 발전기 내부를 마모시키고 부식시키는 원인이 되고, 배관의 부식을 유발한다. 우리나라는 급격하게 바이오가스화 시설이 추진되면서 많은 시행착오로 인한 고장과 효율이 낮은 문제점이 보여 왔다. 전국 11개 바이오가스화 시설의 각 공정 별 가스상의 수분을 측정하였고, 해외기과 발전기 운전적정 수분값을 구하여 바이오가스 이용을 위한 수분함량 가이드라인 설정을 하고자 한다. 국내 소화조 후단 바이오가스 수분측정 결과 음식물/음폐수의 경우 노점온도 26.8 ℃, 절대습도 25.7 g/m3, 상대습도 82.9%로 측정되었고, 가축분뇨는 노점온도 28.7 ℃, 절대습도 28.0 g/m3, 상대습도 82.7%이고, 하수슬러지의 경우 노점온도 24.8 ℃, 절대습도 22.6 g/m3, 상대습도 77.2%로 측정되었다. 또한 제습설비가 운영되고 유지가 잘된 시설의 경우 절대습도 25.5 g/m3에서 12.0 g/m3으로 약 51.1% 감소되었고, 상대습도도 77.2%에서 34.9%로 감소되는 것을 확인할 수 있었다. 반면 제습설비가 미흡한 시설에서는 역으로 증가하는 추세를 보였다. 따라서 국내 바이오가스화 시설에서는 제습처리가 적정수준으로 처리할 경우 노점온도 약 14 ℃를 만족하며, 절대습도 15.4 g/m3과 평균 가스온도인 31 ℃ 기준 상대습도 48%를 유지할 수 있을 것으로 판단하였다.

이산화탄소는 주요 온실가스이며 의심할 여지없이 지구 온난화의 주범이다. 대기의 이산화탄소는 대부분 전기 발전에 사용되는 화석 연료의 연소에 의해 고농도화 되는데, 기후 변화의 억제를 위해서는 대기로부터 이산화탄소를 포획 및 격리가 필수적이다. 한편, 발전소의 소각재는 전기 수요가 증가함에 따라 지속적으로 증가할 것으로 예상된다. 소각재의 증가에 따라 소각재를 활용한 폐기물 자원순환에 관한 관심이 증가하고 있다. 일반적으로 순환 유동층 연소 방법에서는 탈황반응을 위하여 석회석을 인위적으로 첨가하게 되는데, 이 경우, 탈황 반응에 관여하지 않는 잉여 성분은 소각재 중에 CaO 화합물의 형태로 존재한다. CaO와 이산화탄소의 가역적인 반응은 이산화탄소를 제거하는 매우 유망한 방법이다. 특히 상온 상압에서 이루어지기 때문에 매우 경제적이라 할 수 있다. 현재 이와 같은 반응을 토대로 소각재를 이산화탄소와 반응시켜 복합탄산염으로 제조하여 시멘트의 원료로 사용하는 연구가 많이 진행되고 있다. 그러나 대부분의 연구는 다량의 물을 사용하기 때문에 취급이 어렵고, 건조를 위해 많은 에너지가 소모 되는 문제점이 있다. 본 연구에서는 에너지 고효율 공정을 위하여 반건식 복합탄산염 제조를 연구하였으며, 정량분석을 통해 수분의 양이 발전소 소각재의 이산화탄소 포집 특성에 미치는 영향을 연구하였다.

Background: This study aimed to investigate out the influence of drought stress on the physiological responses of Dendropanax morbifera seedlings. Methods and Results: Drought stress was induced by discontinuing water supply for 30 days. Under drought stress, photosynthetic activity was significantly reduced with decreasing soil water content (SWC), as revealed by the parameters such as Fv/Fm, maximum photosynthetic rate (PN max), stomatal conductance (gs), stomatal transpiration rate (E), and intercellular CO2 concentration (Ci). However, water use efficiency (WUE) was increased by 2.5 times because of the decrease in gs to reduce transpiration. Particularly, E and gs were remarkably decreased when water was withheld for 21 days at 6.2% of SWC. Dendropanax morbifera leaves showed osmotic adjustment of −0.30MPa at full turgor and −0.13 MPa at zero turgor. In contrast, the maximum bulk modulus of elasticity (Emax) did not change significantly. Thus, Dendropanax morbifera seedlings could tolerate drought stress via osmotic adjustment. Conclusions: Drought avoidance mechanisms of D. morbifera involve reduction in water loss from plants, through the control of stomatal transpiration, and reduction in cellular osmotic potential. Notably photosynthetic activity was remarkably reduced, to approximately 6% of the SWC.

위성자료는 광범위한 지역의 변동성을 관측하기에 매우 유리하다는 특성 때문에 최근 기후변화로 인한 자연재해 등의 연구에서 각광받고 있다. 하지만 위성자료에도 여전히 시 ․ 공간적인 해상도의 한계가 있으며, 이를 극복하기 위해 다양한 센서의 융합이나 1차 산출물들을 조합하는 방법을 사용한다. 본 연구에서는 천리안 위성의 GOCI와 MI에서 관측되는 자료를 융합함으로써 500 m 공간 해상도의 지표면 온도 자료를 생산하였고, 정규 식생지수와 함께 사용하여 TVDI를 산정하였다. 산정된 TVDI를 통해 한반도의 토양수분 상태를 모니터링 하고자 하였으며, 이를 비교하기 위해 ASCAT 지표 토양수분 자료를 통해 산정된 SSMI와 비교하였다. 그 결과 천리안 TVDI와 SSMI가 대한민국 전역에서 비슷한 공간 분포를 나타냈으며, 천리안 위성을 활용하여 토양수분을 관측할 수 있는 가능성을 제시하였다. 따라서 본 연구에서 산정 된 한반도의 TVDI가 고해상도의 토양수분을 산정하는 기반이 될 수 있고, 이를 통해 천리안 위성의 활용 범위가 보다 확장되어 다양한 연구의 기반이 될 수 있을 것으로 보인다.

Moisture content is an important factor in landfill gas production and effective landfill stabilization management at bioreactor landfills. Moisture content was experimentally estimated by applying the rainfall hydrograph theory through cover materials, such as the general and bio-solid soil, in the Sudokwon landfill site. The rainfall hydrograph theory was used to analyze the water balance, in which moisture can be strongly affected by infiltration in the water balance. Cover material characteristics, such as bulk density, porosity, specific gravity, and hydraulic conductivity, were used to estimate the water balance of the landfill site. From the results of the water balance, runoff was increased, but evaporation and infiltration were decreased with increasing rainfall rate for both general and bio-solid soil. As the bulk density increased in both general and bio-solid soil, runoff was increased, but infiltration was decreased, because hydraulic conductivity in the cover material was decreased with increasing bulk density. Finally, the moisture content of landfill waste increased linearly, with increasing infiltration through the cover materials, even though the increment in moisture content was decreased along the depth of landfill.

The purpose of this study is to corroborate hydration and porosity of cement paste by the low water-cement ratio specimen. The test results show that calcium hydroxide was increased as the moisture was supplied from the outside and the porosity was lowered with a rapid manner.

Suggestions for improvement of allowable nailing stress according for wood: more diverse nail types need to be considered, especially the types most widely used in the field; different fiber directional properties must be differentiated also, future studies need to integrate much required design factors, for example by including the wood temperature/humidity into the integrated modulus, as wood is very sensitive to changes of moisture in the air.

Effects of different soil water conditions on fruit characteristics were investigated in 5-year-old ‘Nero’ black chokeberry trees (Aronia melanocarpa). Three kinds of drought stresses, including low water deficit, severe water deficit, and very severe water deficit, due to decline of soil water decreased the fruit quality of weight of 10 berries, soluble solid content, and anthocyanin, compared with the control (consistent water supply) during the harvest period. After longer drought stress, supply of soil water could induce berry cracking because cell size of epidermis of fruits contracted, whereas cell size of sub-epidermis and flesh expanded. Thus periodic water supply using water supply facility is needed for yield and quality of ‘Nero’ black chokeberry fruits.

We compared the fruit set and the quality of the ‘Niitaka’ pear (Pyrus pyrifolia Nakai) among flowers pollinated by two bee species (Apis mellifera and Bombus terrestris) and pollinated artificial. The artificial pollination rate was 1.3 to 1.9 times higher than the bee pollination rate. Moreover, the artificially pollinated flowers produced fruit that was 5 to 10% higher in weight, 2 to 3% larger in size, and had a higher fruit shape index (L/D) than fruit pollinated by the bees. On economic analysis, net profit from insect pollinator was 93.5 to 97.1% of net profit from artificial pollination. Therefore, artificial pollination is more efficient than bee pollination in ‘Niitaka’ pear. However, regarding fruit quality and net profit, these results suggest that bee pollination can be an good alternative to artificial pollination in ‘Niitaka’ pear.

폐기물의 높은 수분함량은 폐기물 에너지화에 있어 효율을 저해시키는 주된 요인이다. 기계적･생물학적 처리(Mechanical Biological Treatment, MBT)는 생분해성 폐기물의 매립량을 줄이고, 고형연료 생산을 통한 에너지회수를 위해 적용된 기술이다. 최근에는 고품질의 고형연료를 생산하고자 MBT 시설에서 생물학적 처리공정으로 Bio-drying 공정을 적용하고 있다. 본 연구에서는 현재 가동중인 기계적 선별공정 중심의 생활폐기물 고형연료화 시설에서 배출되는 선별 잔재물을 대상으로 Bio-drying이 진행되는 과정에서의 수분제거 특성을 파악하였다. 또한, 특정 범위(45~50℃)로 배출가스의 온도가 유지될 수 있도록 송풍량 자동제어 방식을 적용하였으며, 단일방향의 공기공급에서 기인되는 수분함량의 불균질 분포를 해소하기 위해 송풍방향의 전환을 실시하였다. 2주 동안의 Bio-drying을 통해 폐기물의 40.3%이 감량되었으며, 초기 수분중량 대비 79.4%의 수분이 제거(건조)되었음을 확인하였고, Bio-drying 전/후 폐기물의 수분함량은 각각 43.0 및 14.8%로 분석되었다. Bio-drying 공정에서의 water balance 수립을 통해 송풍방향 전환시점에서의 평균 수분함량이 19.8%로 추정된 반면, 폐기물 상층의 수분함량은 39.0%로 분석되었다. 송풍방향의 전환 이후 실험종료 시점에서의 폐기물 상/중/하층의 수분함량은 각각 23.1, 13.3 및 16.0%로 분석되어, 송풍방향의 전환을 통해 폐기물 상층 수분함량의 효과적인 감소와 수분함량의 균질 분포가 유도될 수 있음을 확인하였다. 또한, 송풍량 자동제어 방식의 적용을 통해 배출가스 온도의 상승 및 하강 시점에서의 송풍량 증가 및 감소에 의해 배출가스의 온도가 특정 범위 내에 존재할 수 있었음을 확인하였으며, 송풍량의 변화가 수분 제거속도를 상승시키는 요인으로 작용한 것으로 분석되었다.

The final goal of this research is to develop a miniaturized botanical biofilter using a wick-typed automatic humidifier for stabilizing soil moisture content (SMC) and purifying indoor air pollutants by the biofilter. This new biofilter equipped with wick-typed automatic humidifier was manufactured as more compacted design removing an absorption tower-typed humidifier compared with the previous big-sized biofilter made in 2015. This study was performed to compare changes of SMCs among floors depending on the number of wicks installed on the humidifier within the novel biofilter, and to compare changes of SMCs and plant growth parameters before and after planting Spathiphyllum wallisii ‘Mauna Loa’ on the biofilter. SMCs among floors depending on the number of wicks were similar, and all regression lines of SMCs showed almost horizontal lines because of long-term stability on SMCs. Comparing plant growth parameters of S. wallisii ‘Mauna Loa’ before planting and at 30 days after planting on the biofilter, all growth parameters were not statistically significant. Thus, SMCs of the biofilter were more stabilized using this humidifying appar
