지방산을 이용한 살충비누의 제조와 이를 이용한 해충의 환경친화적 방제연구를 수행하였고 그 내용을 요약하면 다음과 같다. 1. 각 지방산의 중화가(Acid value)를 기준으로 비누화에 필요한 수산화칼륨의 투입량을 결정할 수 있었으며, 야자지방산의 경우 중화가가 266.3mg KOH/g으로 지방산 1kg당 수산화칼륨 266g이 필요한 것으로 나타났다. 2. 25%의 비누 함량이 되게 제조하기 위해서 지방산별 반응식을 조사하였고, 이에 따라 물의 첨가량을 결정할 수 있었으며, 야자지방산을 이용한 25% 살충비누의 제조에는 지방산 1kg에 수산화칼륨 266g과 물 3.459 ${\ell}$ 가 소요되고 제조된 비누액은 4.644 ${\ell}$인 것으로 나타났다. 또한 사용하는 물은 연수를 이용하여야 하였다. 3. 25% 제조된 살충비누의 물성을 조사한 결과 젤리상의 올레인산 비누를 제외하고는 점도가 낮은 액상이었으며, 산도는 알카리성으로 25% 야자지방산의 경우 pH 9이상으로 나타났다. 또한 50% 이상 고농도의 살충비누를 제조하면 냉각 후 젤리상태가 되어 희석하여 이용하는데 불편하였다. 4. 살충비누 제조공정의 요인으로 반응온도는 중탕방식으로 90$^{\circ}C$이상, 교반속도는 60 ${\sim}$ 120 rpm. 반응시간은 30분 이상이 양호한 것으로 나타났다. 5. 살충비누제조 공정은 중탕, 교반 가능한 반응기를 활용하여 (1) 수산화칼륨 수용액 제조 및 가온(90$^{\circ}C$) (2) 지방산 투입 (3) 30분이상 교반 반응 (4) 냉각을 통해 제조할 수 있었다. 6. 고추진딧물의 포장 방제가 조사시험결과 모든 지방산에서 살충효과를 나타냈으며, 지방산의 탄소수가 낮을수록, 살포 농도가 높을수록, 살포회수가 증가할수록 방제가가 높은 경향이었다. 7. 25% 야자지방산의 경우 50배에서 5일간격 2회처리 후부터 고추에 발생하는 진딧물에 대한 방제가가 92%이상이 되었으며, 100배액에서는 5일간격 3회처리 후부터 94%의 방제가를 나타내었다. 8. 양배추의 복숭아진딧물에 대한 25% 야자지방산 살충비누 50배액의 살포결과 1회 처리후 95%이상, 2회 처리후 100%에 가까운 방제가를 나타냈다. 9. 강낭콩의 점박이응애에 대한 25% 야자지방산 살충비누 50배액, 100배액 살포결과 2회처리 후부터 거의 100%에 가까운 방제효과를 보였으며, 알에 대한 부화억제효과도 인정되었다. 10. 효과증진제 첨가 실험결과 이소프로필알콜 0.1%이상 첨가 살포에서 2회처리시에 약간의 살충력 증진 효과를 보였으며, 규조토 첨가는 효과가 없는 것으로 나타났다. 11. 노지재배 고추의 약해검정결과 25%카프릴산비누 50배액을 제외하고는 약해가 발생하지 않았으며, 25% 카프론산 비누의 100배액은 고추 유묘기에 약해를 나타내었다. 양배추에서는 25% 카프릴산 비누 100배액에서 약해를 보였으나, 25% 야자지방산의 경우 50 ${\sim}$ 100배액 어디에서도 액해를 보이지 않았다. 별도로 적용한 시험에서, 토마토의 경우에도 25% 야자지방산 비누 50 ${\sim}$ 100배액 모두 약해를 발생하지 않았으나, 오이에서는 25% 야자지방산 비누 100배액에도 약해를 나타내었다. 12. 이상의 결과, 천연지방산을 이용하여 유기농업에 허용되는 각종의 살충비누를 제조할 수 있었으며, 방제가 조사결과 진딧물, 응애 등 껍질이 연약한 곤충의 방제에 효과적인 것으로 나타났다. 따라서 제조된 살충비누를 활용하면 환경친화적인 해충방제가 가능하다고 판단되었다.

This study was conducted to investigate the optimum shading material of rain shelter in Panax ginseng C.A. Meyer. Results obtained from our experiment can be summarized as follows. From photosynthetically active radiation (PAR) as shade materials on sunny day, temperature under rain shelter was low in comparison with that under polyethylene net. It was ranged from 3 to $5^{\circ}C$ Survival rate of 3,4, and 5 year-old ginsengs under shade materials of rain shelter was lower than that under polyethylene net. Root fresh weight in ginseng grown under rain shelter was increased into about 5.0g in 3 year-old, 10g in 4 year-old and 8g in 5 year-old ginsengs. From investigating root grade of 3, 4, and 5 year-old ginsengs, we confirmed that rain shelter was more effective than the other as shading materials. Root size of 3, 4, 5 year-old ginsengs grown under rain shelter is distributed in bigger size than that grown under polyethylene net. Also, in the case of saponin contents, the ginseng grown under the shade material of rain shelter was higher than that under polyethylene net.

Vegetable fatty acid solid soap requires a drying process for moisture evaporation and hardness after being manufactured through saponification. Although the soap is manufactured by mixing additives mainly from natural ingredients, existing studies have focused primarily on the usability of vegetable solid soap. Consequently, research into the physical properties of vegetable fatty acid solid soap mixed with natural ingredients has been unsatisfactory. Therefore, this study attempted to compare and observe the changes in the physical properties (pH, surface tension, critical micelle concentration, and cleansing power) of solid soap in accordance with the drying period and additives (tea tree E.O and $TiO_2$) using pH paper, the Du Nouy measurement method, sedimentation method, and ultrasound washer. Regardless of the mixture with additives, vegetable fatty acid solid soap showed the same pH, and there was no change in the pH while maintaining pH 8 beginning from the $2^{nd}$ weeks to $12^{th}$ weeks of drying. In addition, as a result of measuring the surface tension and CMC, regardless of the drying period, only the soap added with $TiO_2$ showed an even value of 62.5mg/L, whereas the other soap specimens showed a decline in CMC to 25mg/L on the fourth week of drying. As a result of measuring the detergency, the removal efficiency of vegetable fatty acid solid soap mixed with tea tree E.O and $TiO_2$ and dried for four weeks was 4.50~4.65%, which was higher than that of the vegetable fatty acid solid soap without additives (3.62~3.92%).

본 연구는 Karr column을 이용한 희토류원소의 분리에 대한 기초 연구로서, 수상의 초기 pH와 유기상 중 PC-88A의 비누화도에 따른 Nd, Sm의 분리특성을 파악하였다. 실험결과 pH $0.8{\sim}2.3$ 범위에서 PH가 높아짐에 따라 Nd, Sm의 추출율 및 분리계수가 증가하였으며, PC-88A 비누화도 40%인 조건에서 추출 후 수상의 초기 PH에 관계없이 평형 pH가 약 1.5 정도로 유지되는 것을 알 수 있었다. 그리고 PC-88A 비누화도가 증가함에 따라 Nd, Sm의 추출율이 크게 증가하였으며, 비누화도 40%인 조건에서 가장 높은 분리계수(${\beta}_{Sm,\;Nd}\;=\;10.8$)를 보여 주었다.

Using the new scouring soap made from rapeseed oil, various scouring test was done souring effects of new scouring soap were estimated. In the effects of scouring soap on the degumming ratio, OS (the soap made from oleic acid) was the most excellent and the next was RS (the soap made from rapeseed oil). Both OS and RS were more excellent than MS (the soap on the market). In a buffer power of soap solution, OS and RS were good, but MS was poor. The uneven dyeing was not observed in the silk fabric degummed by OS and RS, but observed in silk fabric degummed by MS. The value of tenacity and elongation in the silk degummed by OS and RS was higher that degummed by MS. In the crease recovery, softness and whiteness, the order of value was OS, RS, MS.

The aim of this study was to investigate the effect of face wash with ginseng cold process (CP) soap. In order to remove external environmental factors, skin changes were examined immediately after 10 minutes of face wash. The same water and towel were used at the same place. As a control group, the cases of washing with water without using cleanser and with foam cleanser (F/C), which is a popular commercial product, were set. In the case of water washing, there was a significant decrease in pores and pigmentation, but the significance was small. In the case of F/C washing, there was a very significant decrease in pores and pigmentation, but the loss of moisture was rapid. In the case of ginseng cp soap, pores and pigmentation were significantly reduced, while moisture loss was negligible. Ginseng cp soap is considered as a form of face wash that is suitable for skin care.

In the saponification to manufacture plant fatty acid hard soap, the drying process is required for its water evaporation and hardness. This study mixed it with essential oil(E.O) with high volatility instead of adding synthetic flavor. And it comparatively observed the duration of flavor changing to the additive ($TiO_2$) and the drying period of the major flavor component (Linalool, Linalyl acetate) in the essential oil (Lavender E.O) contained in the soap during the soap manufacture by using GC-MS. Advanced researches have mostly dealt with the utility of plant hard soap, and those related with the volatility of flavor have been hardly conducted. Regarding the volatility of linalool contained in the soap, the soap mixed with $TiO_2$ showed a higher reduction ratio up to the 12th week; however, at the point of the 20th week, it reduced to a similar level. Although Linalyl acetate did indicate a slight difference according to the mixture of $TiO_2$, the volatility was shown similar up to the point of the 20th week. During the 20 weeks of drying, the residual rate of linalool was found to be higher than that of Linalyl acetate regardless of the mixture of $TiO_2$. It has been found that the flavor component of lavender essential oil with the duration of two or so days at the room temperature remains for 20 weeks (or 5 months) when it is manufactured through the mixture of plant fatty acid hard soap.
