고추역병에효과가 있는 새로운 침투성 살균제인 Metalaxyl-Mz와 Aliette-F를 실내 및 온실시험으로 수행(遂行)하였으며 그 얻어진 결과는 다음과 같다. 1. 실내 시험에서 약제에 의한 균사신전억제는 전 공시농도에서 Metalaxyl-Mz가 Aliette-F 보다 높은 억제효과 경향을 보였다. 2. 약제에 의한 유주자낭의 형성은 500mg/l 수준에서는 Aliette-F가 Metalaxyl-Mz보다 약간 억제력이 컸으나 그 이상의 농도에서는 두 약제간 큰 차이가 없었으며 무처리보다는 높은 억제경향을 보였다. 그리고 유자낭의 발아억제력은 Aliette-F가 전 농도에서 Metalaxyl-Mz보다 높은 경향이었다. 3. 약제처리한 고추잎에서 추출한 추출물과 혼합한 Corn meal agar 배지상에서 균사신전 억제효과는 무처리에 비해 뚜렷하였으나, 400배와 600배의 두 농도간 균사신전 억제효과는 큰 차이가 없었다. 그리고 약제별 농도의 지속효과는 14일 이상 지속되는 경향이었다. 4. 온실에서 Aliette-F와 Metalaxyl-Mz의 예방효과가 치료효과보다 높은 경향이었으나 공시약제간 뚜렷한 차이가 없었다.

2차원 MT모델링을 수행하여 지자기 수직탐사(GDS)에서의 차이 지시자의 유용성을 조사하였다. 해양과 육지에 위치하는 전도체의 전자기적인 상호 결합 정도는 차이 지시자의 유용성을 판단하는 기준으로서 본 연구에서는 해양과 전도체의 공간적인 위치와 주기에 따른 상호 결합을 조사하였다. 전도체가 지표에 존재하는 경우 해양에서 충분히 떨어져 있거나 사용된 주기가 장주기일 때 차이 지시자가 유용하였고, 전도체가 심부에 매몰된 경우에는 상호 결합이 약해 전 주기에서 차이 지시자가 물리적인 의미를 가졌다. 그러나 전도체가 지표로부터 심부까지 확장되어 있는 경우 상호 결합이 장주기까지 강하게 영향을 미쳐 차이 지시자의 유용성을 확신할 수 없다. 따라서 획득된 유도 지시자로 부터 해양처럼 이미 알고 있는 전도체의 효과를 제거하기 위해서는 수치 모델링을 통한 전도체 간의 상호 결합에 대한 정보가 요구되며 상호 결합이 큰 경우 차이 지시자의 해석은 정확하지 않으므로 주의해야한다.

본 연구는 브랜드 애착이 제품의 내형 변형 행동과 사용상황 확장행동에 미치는 영향에 있어 제품 속성 정렬가능성(attribute alignability)의 조절적 역할을 파악하는 연구이다. 실험을 통한 연구 결과 브랜드 애착이 높을수록 제품 내형변형행동과 제품 사용상황 확장행동이 더 크게 나타났으며, 브랜드애착이 높은 소비자는 브랜드 애착이 낮은 소비자에 비해 상대적으로 속성 정렬 가능 차별점이 높을수록 제품의 내형변형행동이 크고, 속성 정렬 불가능한 차별점이 클수록 사용상황 확장행동에 미치는 영향이 크게 나타났다. 이는 기업에서 소비자의 제품 내형변형행동에 있어, 제품에 대한 속성정렬 가능 차별점을 높임으로써, 브랜드 애착을 강화하고 충성고객을 확보할 수 있을 것이다. 또한 제품 사용상황 확장행동에 있어서는 제품에 대한 속성정렬 불가능 차별점을 통해 경쟁제품 속성과 차별화하여 브랜드 애착을 강화하고, 자사 제품에 있어 차별적 경쟁우위로 활용할 수 있다.

The purpose of this study was to investigate the difference of visual evaluation about silhouette image. The specific objective were; 1) to construct of silhouette image evaluation instrument using semantic differential scale for the purpose of measuring the width and length; 2) to identify the factor structure of the silhouette; 3) to test the difference of visual perception to the silhouette as the variation of width; 4) to test the difference of visual perception to the silhouette as the variation of length; 5) to test interaction effect between width and length. The major finding were; For the visual evaluation of silhouette as shoulder width variatiorl, there were significant difference in hardness and softness factor. For the hard and soft image, we should express by variation of the shoulder width. For the visual evaluation of silhouette as skirt width variation, there were significant difference in attention factor. For the attensive image, we should express by variation of the skirt width. For the visual evaluation of silhouette as skirt length variation, there were significant difference in activity factor. For the active image, we should express by variation of the skirt length.

Unlike the case of $Ir(ppy)_3$, various aggregates of PtOEP including dimer are formed in PtOEP-doped films and neat film. Such a difference is due to difference of competition among solid state solvation effect, dipole-dipole interactions between dopant molecules, and intermolecular covalent bonding.

Body position is known to have an effect on vital capacity(VC). The purpose of this study was to examine effect on VC of posture, sex and smoking, and the difference between predicted and measured values of VC. VC was measured in the standing and the $30^{\circ}$ head-down position in 40 healthy subjects (20 men and 20 women) in a random order of testing. When subjects changed from standing to head-down position, this VC decreased by 19.9%. In both positions, VC changes in men were significantly larger than in women. No statistically significant difference was found in men who smoked. There was no difference between the predicted and measured values in men. But measured values were larger than predicted values in women. Because VC can decrease by 19.9% in the head-down position due to the effect of gravity, attention should be paid especially to patients who are placed in the head-down position for postural drainage since they already have a decreased VC.

In order to study the tenderizing effect of the proteolytic enzyme, ficin, from fig fruit (Ficus carica L), the enzyme was purified from fig latex by precipitation and chromatography. The ficin separated from Bongraesi showed single band on SDS-PAGE. However, the ficin from Masui showed tow bands. The specific activity of ficin purified from Bongraesi species was 2.8 unit/mg protein and that from Masui species was 6.5 unit / mg protein. The amounts of ficin purified from 50 mL of crude latex of Bongraesi and Masui were 1,760 mg and 657 mg, respectively. the water holding capacity of beef decreased to the large extent, when sugar Bongraesi latex and Masui latex were added. The hardness of beef showed decreasing tendency with the time, however, after 60 min, it decreased and thereafter increased a little after 120 min. the hardness of beef decreased sharply with addition of the latex of Bongraesi and Masui. The Masui has more tenderizing effect than the Bongraesi. When meat was mixed with tenderizing agent(ficin) and not heated, the change of color showed significant difference (p＜0.01). when meat was mixed with tenderizing agent(ficin) and heated, the toughness showed significant difference (p＜0.01) and the softness showed significant difference (p＜0.001).

The present study was undertaken to examine the effect of butylhydroxyanisole (BHA) on the lead poisoning in Wister female rats. All experimental rats except normal group were fed with diets formulated by adding BHA in a range of 0.1% to 3.2% and aqueous solution of 1% lead acetate ad libitum through the experimental period. The results obtained are summarized as follows: 1) Lead sedimentation in kidney tissue was decreased with increasing experimental period and BHA level of lead plus BHA-treated groups in comparison with that of lead-treated control group. 2) The weights of lung, spleen and left/right (L/R) kidney were significantly decreased in comparison with those of lead-treated control group after 2 weeks of experimental period, but no difference was shown with those of normal group. 3) The weights of lung, spleen and L/R kidney were increased in lead-treated control group as compared with normal group after 2 weeks of experimental period, but no difference was shown with increasing experimental period. 4) Water intake was remarkably decreased in lead-treated control group as compared with normal group, but water intake by increasing BHA level of lead plus BHA-treated groups showed no significant difference from that of normal group. 5) These results suggest that BHA is effective for reducing the toxic effect of lead in rats.

The purpose of this study was to compare acupuncture-like transcutaneous electrical nerve stimulation(ALTENS) with conventional transcutaneous electrical nerve stimulation(C-TENS) for crossover effect in healthy subjects. Forty subjects recieved ALTENS(20 persons), C-TENS(20 persons) to one upper extremity. Each technic was applied to the motor point of the wrist extensor muscle group for twenty-minutes. With the subject placed in supine the technics were applied at 80 Hz, 2-10 mA(ALTENS) and 10 Hz, 4-12 mA(C-TENS). Results revealed: (1) a significant difference between the pretreatment and posttreatment in each group(p<.05) (2) no significant difference between ALTENS and C-TENS(p>.05). In conclusion, there was no difference between ALTENS and C-TENS for crossover effect.

This research presents a laboratory study about difference of subjective response between with and without pictures. A main source is impulsive sound caused by leisure shooting. The sources are sampled from outdoor noise and their levels range from 40 to 75 dB at the interval of 5dB. The noise unit is based on A-weighted sound exposure level (ASEL; $L_{AE}$). To make equal ASEL of outdoor noise, finite impulse response (FIR) filter is applied to the originally sampled source to include the effect of distance attenuation. The evaluation method of the jury test adopted a Semantic Difference(SD) Method. The intersection point which two lines crossed was used as reference point. The intersecting point of mean response rating between with and without pictures was approximately 44ASEL and that of %HA was about 60ASEL. In the result of the test, the negative effect of pictures was given at a lower levels than intersection point while the positive effect was given at a higher levels than that.
