배철섭,한규홍,김병용 경희대학교 생명자원과학연구원 2000 硏究論文集 Vol.21 No.-

고추장을 각 저장온도에서 숙성하였을 때 환원당과 아미노태 질소는 증가하였고 점도, 색도, 전분 입자 수는 감소하였다. 높은 저장온도에서 모든 품질인자들의 증가와 감소가 빠르게 진행되었으며, 점도의 경우 저장기간이 끝난 후 온도에 따른 차이를 보이지 않았다. 점도, 색도, 전분 입자 수에 대한 반응 속도는 1차 반응을 나타내었으며, k값은 20℃보다는 35℃에서 높게 나타났다. 이러한 결과는 20℃보다는 35℃에서 숙성이 빠르게 일어남을 보여주는 결과이다. 고추장의 숙성에 있어서 단기간에 숙성을 필요로 할 경우 고온에서 숙성하는 것이 좋으나, 장기적으로 숙성을 원할 경우에는 상온에서 숙성하는 것이 좋을 것이라고 생각된다. 영상분석을 이용한 입자수 측정결과와 점도, 색도 측정간의 결정계수(r^2)가 상당히 높은 값으로 나타나 영상분석을 통한 저장 수명 예측을 가능하게 하였다. The fermentation degree of kochujang during storage at different temperature was predicted by viscosity, color and particle numbers determined by an image analyzer. Reducing sugars and ammo-nitrogen contents of kochujang were increased during storage, whereas color (lightness, redness, and yellowness) of kochujang was decreased at all storage temperatures. The difference in viscosity at each storage temperature was less as storage time was increased. Above parameters at various storage times followed the first oder reaction pattern and the rate constant (k) was mostly dependent on storage temperature. The relationship of particle number and storage time of the Kochujang was applied to a simple regression model, to be able to predict fermentation time.

A base structure which mounts positioning stages is often subjected to vibration due to the reaction force against the stage motions. This paper deals with an input shaping method for positioning stage in consideration of vibration base structures along with the stage vibration. A dynamic model is established to investigate the vibration of positioning stage and base structure. Two input shapers, a conventional input shaper and a new input shaper, are applied to eliminate both the residual vibrations in base structure as well as positioning stage. Simulations show that the input shaping methods effectively remove the residual vibrations.

This study examines the relationships beteween social strata and children's socialization in Taegu City. Taking advantage of theories of B. Bernstein(1973) and M. Kohn(1977), two researchers developed their own hypotheses as follows. (1) The upper strata are socializing their children for the purpose of cultivating one's talent in a democratic/self-determined way : (2) The middle strata demand their children to be achievementoriented people in an authoritarian/regulated way : and (3) The lower strata are socializing their children either in a laissz-faire way or in a threatening way in order to make them self-contented. The survey results did not neatly fit into the researchrs' hypotheses. Regardless of social strata, most parents want their children to be polite and courteous. It appears that there does not exist a class-specific and consistent way of socializing children.

연약 점토지반 성토시 Geotextile 효과의 실험적 연구

김수일,배규진 연세대학교 산업기술연구소 1982 논문집 Vol.14 No.1

Geotextile effects for embankments on weak clays are studied through the laboratory model experiments. The experiments are carried out in four stages; no geotextiles between clay-crushed stone boundary, geotextiles with no pretensioning, and two different geotextile pretensionings. The experimental model has dimensions of 32cm x 330cm in plan. The height for the clay container is 60cm. The 47cm height of crushed stones are laid on top of the 50cm clay layer. When geotextiles are employed, the geotextiles are laid between clay-crushed stone boundary. The time dependent deformations are measured utilizing the LED indicating lamp matrix inserted in the crushed stones and the dial gages put on top of the clay layer where the crushed stones are not laid. The measurements are carried out for 15days which is approximately equivalent to the 50% consolidation level. From the experiments, it is found that the geotextiles are more effective in horizontal displacement reduction than in vertical displacement reduction, especially when the geotextiles are pretensioned before embankments. It is also found that the time dependent settlement behavior is almost identical whether geotextiles are applied or not, and that the vertical displacements when geotextiles are employed are linearly decreased with increasing tensile stresses developed in the geotextiles.

This study was undertaken to define the effect of Crataegi Fructus on the norepinephrine-induced arterial contraction and the mechanism of Crataegi Fructus-induced relaxation. In order to investigate the effect of Crataegi Fructus on contracted rabbit carotid arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. To analyze the mechanism of Crataegi Fructus-induced relaxation, Crataegi Fructus extract infused into contracted arterial strips induced by norepinehrine after treatment of indomethacin, N_(t) nitro-_L-arginine or tetraethylammonium chloride. Crataegi Fructus relax arterial strip with endothelium contracted by norepinephrine, but in the strips without endothelium, Crataegi Fructus-induced relaxation was significantly inhibited. The endothelium-dependent relaxation induced by Crataegi Fructus was decreased by the pretreatment of N_(t) nitro-_L-arginine, but it was not observed in the strips pretreated with indomethacin or tetraethylammonium chloride. We suggest that Crataegi Fructus may influx of extra-cellular Ca^++ through the formation of nitric oxide in the vascular cells.

Soil-Geotextile System의 이론 및 실험적 연구

김수일,배규진 연세대학교 산업기술연구소 1984 논문집 Vol.16 No.1

The effects of geotextile for embankments on weak clays are studied through the laboratory model experiments and the theoretical analysis based on "load-decrease effect" caused by geotextile. The experiments are carried out in four stages; no woven fabrics between clay-crushed stone boundary, fabrics between boundary with no initial pretensioning of fabrics, and fabrics, and fabrics between boundary with two different initial pretensionings of fabrics. In all stages, vertical drains utilizing non-woven fabrics are installed in the clay layer in grid pattern to accelerate the consolidation. The experimental model has dimension of 32㎝x330㎝ in plane. The height for the container is 60㎝. The 47㎝ height of crushed stone embankment is constructed over the 50㎝ deep clay layer. When geotextiles are employed, the geotextiles are laid between clay-crushed stone boundary. The measurements are carried out for 10 days which is equivalent to the time required for the primary consolidation. Theoretical analysis of soil-geotextile system is carried out by applying "load-decrease effect" caused by geotextile to the theoretical analysis of plane strain consolidation without geotextile. For the analysis of plane strain consolidation without geotextile, the computer program developed by A. verruijt is used. The program is based upon a sub-division of the problem field into triangular elements, with the displacement components and the pore stress defined in each node, and linear interpolation in the elements. The predictions of deformations at the base of model embankment show relatively good agreement with the measured values. Especially, the predictions of heaving deformations with geotextile show fairly good agreement with the measured values.

손규목,김광호,성태수,김종현,신동주,정지영,배영일 한국식품영양학회 2002 韓國食品營養學會誌 Vol.15 No.2

단감의 기능성 소재 및 기호성이 우수한 부원료로서의 이용 가능성을 확인하기 위하여 단감새옥를 전처리별 즉, 열처리 온도 (25℃, 75℃ 및 95℃) 에서 NaCl (0, 1, 3%) 농도별로 침적 (1, 5분) 하여 동결건조한 시료구를 대상으로 탄닌, 비타민 C, 색도 및 조직감 등을 분석한 결과는 다음과 같다. 탄닌 성분은 열처리 온도, NaCl 농도 및 침적시간이 증가할수록 탄닌함량이 감소하는 경향을 나타내었으며, 특히, 대조구 (420 mg%) 에 비해 95℃에서 1% 및 3% NaCl 농도에 5분간 침적시 각각 228 및 198 mg%로 감소하였다. 비타민 C 함량은 대조구 (122.4 mg%)에 비해 95℃에서 3% NaCl 농도에 5분간 침적시 75.8 mg% 로 감소하였고, 색도는 열처리 온도, NaCl 농도 및 침적시간이 증가할수록 L(명도) 및 b(황색)값이 뚜렷하게 증가한 반면, a(적색도) 값은 감소하였고, ??E 값은 증가하여 처리조건이 가중될수록 색의 변화가 진행됨을 알 수 있었다. 단감껍질과 전처리한 시료 (95℃, 1% NaCl, 5 분)의 flavonol 함량은 껍질에 myricetin(2.0 ㎍/g), quercetin (34. 5 ㎍/g) 및 kaemferol (1.1 ㎍/g) 성분이 검출되었고, 전처리한 시료는 myricetin (9.5 ㎍/g), quercetin (5.5 ㎍/g)이 검출되었다. 조직감은 대조구에 비해 전처리 (95℃, 1% NaCl, 5분) 한 시료에서 부서짐성, 응집성, 점성 및 씹힘성이 우수하였다. 관능검사는 95℃에서 1% NaCl에 5분 및 3% NaCl 농도에 1부간 침지한 시료가 좋은 평가를 받았다. Sweet persimmon were tested in order to identify their use as secondary material which is excellent in function and taste as food. Samples were soaked for 1 and 5 min with NaCl concentration (0, 1 and 3%) at a certain heating temperature (25, 75 and 9r℃), and then tannin, vitamin C, flavonol, color intensity, sensory test and textural properties were analyzed. The results of the analyses were as follows. Tannins were decreased as heating temperature, NaCl concentration and soaking time were increased, especially, that the control was 420 mg% but decreased 228 and 198 mg% at 95℃ (1 and 3% NaCl concentration) for 5 min, soaked in each. Vitamin C content also decreased more in higher temperature and NaCl concentration than control (122.4 mg%). Color intensity showed higher value in L and b than in heating temperature, NaCl concentration and soaked time longer remarkably, but a value decreased. The peel of sweet persimmons was analyzed myricetin (2.0 ㎍/g), quercetin (34.5 ㎍/g) and kaemperaol (1.1 ㎍/g), but in pre-treatment sample ( 95℃, 1% NaCl concentration and 5 min, soaked ) was showed higher myricetin (9.5 ㎍/g) and quercetin (5.5 ㎍/g). Textural properties were good in pre-treatment sample ( 95℃, 1% NaCl concentration and 5 min, soaked) such as brittleness, cohesiveness, gumminess and chewiness. In sensory analysis, the pre-treatment samples (95℃, 1% NaCl concentration and 5 min, soaked and 95℃, 3% NaCl concentration and 1 min, soaked) were showed higher point than others.
