송인규,Song, In-Gyu 에너지절약전문기업협회 2008 esco Vol.55 No.-
에너지원의 대부분을 수입하고 있는 우리나라는 현재 에너지원의 수입비용 상승에 따라 기업의 에너지비용 또한 급상승하고 있는 상황이다. 이러한 에너지 비용의 급상승은 기업의 생산원가상승의 주요 원인이 되며 이는 지금 기업 경쟁력의 약화를 초래하고 있다. 이러한 상황에서 에너지 절감을 통한 생산원가의 절감은 곧 기업의 성패와도 직결되어 있다고 해도 과언이 아니다. 그렇다면 기업 입장에서 에너지 절감을 위해 할 수 있는 최선의 방법은 무엇인가? 바로 ESCO를 활용하여 기술적, 경제적 부담없이 에너지절약시설을 설치하는 것이다.

This study was conducted to investigate the effects of cultural soil textures on growth and quality of Glycyrrhiza uralensis Fischer from 2009 to 2010. The obtained results from this study were summarized as follows; The growth of stem and leaf were superior to one year old G. uralensis, and surface runner and root growth tended to be better in 2 years old G. uralensis. The weight of stem and leaf were heavy in sandy loam, and plant height, branches, stem diameter in sandy clay loam were better than other soil texture. The growth characteristics, such as length, number and weight of surface runner, was better in order of sandy clay loam > sandy loam > loamy sand. The length of main and lateral root was longer in loamy sand soil than other treatments, and the diameter of main and lateral root was more thicker in sandy loam than others. The number of lateral root was higher in the sandy loam than other treatments. The yield of main and lateral root was in order of sandy loam > sandy clay loam > loamy sand soil. Marketable root yield of one year old and two year old G. uralensis were increased 57% and 71% in sandy loam compare to a loamy sand as 204 kg/10 a, respectively. The content of glycyrrhizinic acid was the hightest as 1.62% in sandy clay loam soil in one year old, and as 1.58% in sandy loam soil in two years old of G. uralensis, respectively.

노지 고추재배시 경운 깊이에 따른 유기물 함량을 구명하여 지속적 안전생산에 활용하고자 경운 깊이는 10, 30 및 50 cm로 하고 퇴비의 양을 1, 3 및 5 톤 10a<SUP>-1</SUP>으로 처리하여 고추를 재배한 결과 다음과 같다. (1) 시험후 토양의 pH는 모든 처리에서 시험전 토양보다 낮아졌으며 EC를 비롯한 Av. P2O5, K, Ca, Mg,Na는 시험전보다 높았다. 퇴비 시용량 별로는 퇴비 1 톤 10a<SUP>-1</SUP> 및 3 톤 10a<SUP>-1</SUP> 처리에 비해 퇴비 5 톤 10a<SUP>-1</SUP>에서 높았다. (2) 고추 생육은 퇴비 1 톤 10a<SUP>-1</SUP>처리에 비하여 퇴비 3톤 및 5 톤 10a<SUP>-1</SUP>에서 좋았으며, 경운깊이 10 cm 및 30 cm에 비해 경운깊이 50 cm에서 좋았다. (3) 고추 수량은 경운깊이 10 cm에서는 퇴비 3 톤 10a<SUP>-1</SUP>처리에서 5,880 kg ha<SUP>-1</SUP>으로 가장 좋았고, 경운 깊이 30 cm 에서는 퇴비 5 톤 10a<SUP>-1</SUP> 처리에서 5,610 kg ha<SUP>-1</SUP>으로 가장 좋았다. (4) 고추식물체의 T-N 함량 및 흡수량은 퇴비 3 톤 10a<SUP>-1</SUP> 및 5 톤 10a<SUP>-1 </SUP>처리에서 1 톤 10a<SUP>-1</SUP>처리에 비해 높았다. Experiments were conducted to find out the optimum amount of compost and tillage depths in pepper cultivation. Red pepper was grown in different plots with 10 cm, 30 cm, and 50 cm in tillage depth, and was applied with 1 ton, 3 ton, and 5 ton 10a<SUP>-1</SUP>, respectively. The pH value in soil showed lower level after experiment than before experiment, however, the contents of the EC, Av. P2O5, K, Ca, Mg, and Na were increased after experiment. The chemical contents in soil after experiment showed higher level in compost 5 ton 10a<SUP>-1</SUP>. The growth of red pepper in field was enhanced in the compost treatment of 3 ton, 5 ton 10a<SUP>-1</SUP>, and tillage 50 cm plot. In tillage 10 cm plot, yields of red pepper showed the highest amount as 5,880 kg ha<SUP>-1</SUP> with compost 3 ton 10a<SUP>-1</SUP>. In tillage 30 cm plot, the yields of red pepper showed the highest as 5,610 kg ha<SUP>-1</SUP> with compost 5 ton 10a<SUP>-1</SUP>. The T-N contents and uptake in the red pepper plant increased in the compost in 3 ton 10a<SUP>-1</SUP> and 5 ton 10a<SUP>-1</SUP> compared to 1 ton 10a<SUP>-1</SUP>. These results suggest that different amounts of compost should be applied when we cultivate crops with different tillage depth.

This experiment was carried out to get a basic information of yields and qualities as affected by 5 treatments including 10% cutting rate of branch-top with a view to reducing operating cost in the non-supporting cultivation system as an alternative of the staking cultivation system in Cynanchum auriculatum Royle ex Wight. The results were as followed; growth of branch-top by non-supporting culture seemed to be poor as compared to the staking one(conventional method). In non-supporting culture, lower rate of cutting of branch-top of the plants showed longer vine length, whereas higher rate of cutting resulted in thicker stem diameter and plenty of branch number. In view of leaf width in cutting rate of branch-top, the lower, the broader, but the chlorophyll content would be higher by increased rate of cutting of branch-top. Tuber growth seemed to be good in staking cultivation as compared to non-supporting cultivation. And marketable yield of no cutting of branch-top of the plants would be 559kg/10a, while 10~20% cutting rate of branch-top increased by 9~13% in non-supporting cultivation. The results obtained showed the optimal branch-top cutting ratio of non-supporting cultivation of which could be labor-saving farming technologies be 20% as an alternative of the staking cultivation system in Cynanchum auriculatum Royle ex Wight.

본 연구는 장류시장을 개척할 수 있는 속성장을 발굴하여 장류 소비확대와 장류산업 발전에 기여하고자 메밀을 이용한 속성장을 제조하였고, 그 실용화와 대량화를 위하여 메밀의 배합비, 염도 및 수분함량을 결정하고자 하였으며, 제조 후 다양한 품질특성을 조사하였다. 그 결과, 4 종류 속성장의 초기 수분함량은 52~64% 수준으로 다양하였고, 숙성기간이 길어질수록 수분함량이 조금씩 감소하여 숙성 70일째는 53~58%를 나타냄으로써 시료 상의 아주 큰 차이는 보이지 않았다. 메밀 속성장의 pH는 숙성 70일째 5.1~5.6의 값을 나타내었고, 총산의 경우 0.6~0.8%의 범위로 염 함량이 낮은 된장일수록 높은 산도를 보였다. 총 미생물 균수는 70일째까지 감소하여 전반적으로 1~3 log cycle 정도 균수가 감소하였다. 초기 발효기간엔 모든 시료에서 44~89 mg% 분포로 아미노태 질소의 함량을 보이다 숙성이 진행될수록 함량이 꾸준히 증가하여 152~213 mg% 함량을 나타내었다. 발효 70일 된 메밀 속성장의 관능검사 결과, 전체적인 기호도는 처리 간에 유의차가 있는 것으로 나타났으며, 대조구와 실험구 C가 가장 높은 값을 보였고 그 다음으로 B, D 순으로 나타났다. 따라서 현장에 적용할 수 있는 메밀 속 성장은 찐콩과 메밀을 8.5:1.5의 비율로 만든 메주를 10% 염도에서 메주의 1.5배의 수분을 첨가하여 만드는 것이 메밀의 함량을 낮추면서 관능적인 면과 다양한 생리활성 면에서 차이가 적은 상업용 메밀 속성장의 배합비라고 생각된다. This study was conduct in order to provide information on formula optimization, salinity, and water content for commercialization of traditional buckwheat Soksungjang. To do this, we determined quality characteristics such as total microbial flora counts, amino-type nitrogen content, total polyphenol content, antioxidant activity, and performed a sensory evaluation. The moisture contents showed a gradual decrease during the fermentation period. There was no significant difference in all samples. During 70 days of fermentation, the pH showed a similar trend starting at a pH of 6, and dropping sharply to 5.5, except Experiment C (15% buckwheat powder in the meju, 10% NaCl, and 130% water in the total Soksungjang). On the other hand, total acidity increased regularly, however, its ranges were various points in all samples. The microbial population was reduced by 1~3 log cycle in all samples during the fermentation period. The content of amino-type nitrogen showed a gradual increase during fermentation, ranging from 160 to 213 mg% after 70 days. No remarkable difference in total polyphenol content and antioxidant activity was observed in all samples. In sensory evaluation, Soksungjang with 30% (control) and 15% (Experiment C) buckwheat showed a significantly higher overall score.

The sintering process in alumina (Al2O3) specimens for a functional ceramic anchor was investigated and the physical and mechanical properties of the sintered samples were analyzed. MgO (from 0.25 wt% to 3.0 wt%) as an additive was added and sintered at various temperatures (1450 ℃, 1550 ℃, and 1650 ℃) using a conventional solid state sintering process. The sintered density, flexural strength and compressive strength were investigated for the mechanical strength evaluation. The 2.0 wt% MgO added Al2O3 samples (sintered at 1650 ℃) showed a maximum flexural strength of 354.82 MPa and compressive strength of 1615.2 MPa. These experimental results suggested that the sintering temperature and the amount of additives played an important role in enhancing the density and mechanical strength because of the micro-structure modification by MgO addition in the Al2O3 sintered samples. We expect to be able to produce ceramic anchors using the experimental conditions with the best mechanical and physical properties.
