본 연구는 인삼저온숙성비누의 세안효과를 연구하기 위하여 진행하였다. 피부상태에 영향을 줄 수 있는 외부적 환경인자를 배제하기 위하여 동일한 환경에서 동일한 물과 타월을 사용하였으며, 세안 전과 세안 직후 10분의 피부변화를 조사하였다. 대조군으로는 세안제를 사용하지 않고 물세안만 한 경우와 시중에서 일반적으로 사용되고 있는 폼클렌저 타입의 세안제를 사용한 경우를 설정하였다. 물세안, F/C세안, 인삼cp비누 세안의 세 가지 케이스를 비교 분석하였으며 물세안의 경우 모공과 색소침착을 유의성있게 감소시켰으나 F/C세안과 인삼cp비누에 비하여는 유의성이 크지는 않았다. F/C세안의 경우 모공과 색소침착을 유의성이 크게 감소시켰으나 세안 후 급격한 수분감소가 나타났다. 인삼cp비누를 이용한 세안의 경우 모공과 색소침착을 유의성 크게 감소시키면서도 수분의 손실은 크게 나타나지 않았다. 그러므로 인삼cp비누는 피부관리를 함에 있어서 가장 적합한 세안제의 형태라고 사료된다.

Objectives : Cleanser is the most basic tools used in daily skin care. I made a cold process soap using Castanea crenata inner shell (CCIS). I'd like to study the effect of face wash using CCIS cold process (CP) soap on the skin. Methods : The same water and towel were used at the same place in order to examine the skin change state immediately before and after washing face. The skin test was performed before and after 10 minutes washing the face in order to remove these external environmental factors, such as lifestyle, alcohol, tobacco, and stress etc. As a control group, the cases of washing with water and foam cleanser (F/C), which is a popular commercial product, were set. Three cases were compared and analyzed. Results : In the case of water washing, there was a significant decrease in oil (U-zone) but that was not good effect. In the case of F/C and CCIS washing, there were significant decrease in oil (T-zone), pores and pigmentation, but the significance was bigger in CCIS washing. In the case of pores, there was a significant decrease in all three cases. Conclusion : In the case of F/C and CCIS washing, it showed the effect of reducing T-zone oil, pores and pigmentation. But the significance was greater in CCIS case than in F/C case. CCIS cp soap is considered as a form of face wash that is suitable for skin care.

Objectives : In previous studies, I presented various effects of Seosiokyongsan (SSOOS) cp soap on facial skin. However, in the case of skin clinical trials, various factors such as lifestyle, alcohol, tobacco, and stress could not be excluded. The purpose of this study was to investigate the effect of face wash using SSOOS cp soap on the skin without environmental factors. Methods : The same water and towel were used at the same place in order to examine the skin change state immediately before and after washing face with SSOOS cp soap. The skin test was performed before washing the face and after 10 minutes washing the face to compare the changes. As a control group, the case of washing with water without using cleanser and the case of washing with S-K cleanser, which is a popular commercial product, were set. Three cases were compared and analyzed. Results : In the case of water washing, the decrease in moisture was similar to that of the S-K cleanser and the amount of oil and pores decreased, but it was weaker than that of the S-K cleanser. The SSOOS cp soap showed a decrease in oil, pores, and pigments, but it was not significant, the moisture showed a significant decrease, but it was mild compared to S-K cleanser and water wash. Conclusion : In the case of SSOOS cp soap, the stimulation caused by facial cleansing was the least, showing a gentle change.

Objectives : The researcher had investigated the efficacy of ginseng using Microneedle Therapy System (MTS) and confirmed the effect of ginseng Cold Process (CP) soap just before and after washing face. The purpose of this study was to find out what kind of effect appeared through a period of 6 weeks when environmental factors were involved using ginseng CP soap. Methods : The researcher selected 47 subjects, 37 as the experimental group and 10 as the control group. The researcher asked participants to wash their face twice a day in the morning and evening using ginseng CP soap, and the period was set for 6 weeks. The researcher had the people who selected as the control group use a commercially available foam cleanser. They performed a skin test before the start of the test, and the change status was continuously investigated 2 weeks, 4 weeks, and 6 weeks after using the soap. Results : In the case of T-zone oil, there was a significant decrease in the use of foam cleansing and ginseng CP soap, and in the case of pores and pigmentation, a significant decrease was observed only in the use of ginseng CP soap. In skin tone change, there was a significant effect in both the experimental group and the control group, but the significance was greatly increased in the case of ginseng CP soap compared to foam cleansing. Conclusions : Ginseng CP soap is considered to be a more suitable cleanser for skin care compared to foam cleansing.

Objectives : Many people use natural soap instead of commercially available bar type general soap for skin care. They tend to prefer cp (cold process) type soaps that go through a sufficient maturation process in formulation. The purpose of this study was to investigate the efficacy of PCPS (placenta cp soap). Methods : The researcher selected 36 subjects, 28 as the experimental group and 8 as the control group. I asked participants to wash their face twice a day in the morning and evening, and the period was set for 6 weeks. The researcher had the people who were selected as the control group use a commercially available foam cleanser, meanwhile the experimental group use PCPS. They performed a skin test before the start of the test, and the change status was continuously investigated after 2 weeks, 4 weeks, and 6 weeks after using the soap. Results : In the case of U zone oil and pores, there was a significant decrease and in the case of skin tone, there was a significant increase in the group of using PCPS. In T zone oil change, there was no significant effect in both the experimental group and the control group. Conclusion : In the case of PCPS, it is recommended to use it in the effect of reducing the size of pores and increasing skin tone, but it can reduce u-zone oil content.

본 연구에서는 포세린 소성과정 동안 금속하부구조물의 경도가 하강하는 문제점을 개선하기 위해 모의소성 시 산화처리 단계에서 서냉(bench cooling) 대신 급랭(ice-quenching)으로 합금을 냉각시킴으로써 나머지 소성단계 동안 경화효과를 얻을 수 있을 것으로 예측하고, 이를 확인하기 위해 실험을 진행하였다. 본 연구에서는 Pd-Ag-Sn-Au계 금속-세라믹용 합금을 사용하여 실험을 진행하여 다음과 같은 결과를 얻었다. 산화처리 후 stage 0으로 냉각한 시편과 산화처리 후 급랭한 시편을 glaze까지 모의소성한 결과, 두 시편 모두 소성 첫 단계에서 경도가 상승한 후 지속적으로 경도가 하강하였으나, 산화처리 후 급랭한 시편의 최종 경도가 더 높게 나타났다. 소성 첫 단계에서 일어난 경도의 상승은 면심입방구조의 Pd-Ag-rich 기지에서 면심정방구조의 Pd3(Sn, Ga, In)상의 석출로 인해 기지와 석출물간의 계면에 생성된 격자변형에 기인하였다. 모의소성과정에 따른 경도의 하강은 석출물이 조대화됨에 따라 석출물과 기지사이의 계면의 면적이 감소되어 격자 뒤틀림이 해소된 것에 기인하였다.

Objective : We have reported the effects of Seosiokyongsan (SSOOS) cp soap on increasing skin moisture, decreasing pore size, and reducing acne symptoms on previous studies. But in the case of SSOOS soap, many soap bases were used in the making process. So we could not determine whether the above test results were the effect of soap bases or SSOOS herb medicine. Therefore, We conducted this clinical test to find out the effect of SSOOS itself. Methods : We made two kinds of soap. One type was made of cp soap using only soap bases and gave them to 10 subjects. The other type was cp soap made by adding SSOOS to the soap base and gave them to 25 subjects. The other 10 subjects did not limit the soap. Subjects were asked to wash their face with soap in the morning and evening for six weeks. The test was conducted three times and the results were compared and analyzed. Results : In the test group using the SSOOS soap, the oil in the U zone was significantly decreased and the moisture was significantly increased compared to other two control groups. Pores size and pigmentation were decreased but not significant. There was a significant increase in moisture in the soap base group, but that was a slight increase compared to SSOOS soap. There was no significant results in the without soap control group. Conclusion : SSOOS soap was found to have a significant effect on facial skin as cleansing products.

Objectives : The pores are the openings of sebaceous glands or apocrine glands. They are enlarged by various factors such as sex, age, genetic influence, sebum secretion, acne and so on. When the pores are visually recognizable, they become aesthetically problematic. There are various methods of treating pores, but we have tried to develop a method to reduce pore size by using daily cleanser. Methods : Facial skin examination was performed on 104 students of A university. Among them, 10 persons with large pore size were selected. We surveyed 72 students to determine their subjective skin condition, lifestyle, and washing habits etc. We made herbal fermented soaps using Seosiokyongsan and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal fermented soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. After the experiment, the changes of skin were measured and analyzed through facial analysis test. Results : In our experiment, the early 20s, 9.6% of the students had slightly larger pores. For students with large pores, there was a high likelihood of side effects from using facial products. Using the fermented soap made of Seosiokyongsan, the average size of the pores and the number of large-sized pores were significantly reduced. Conclusion : Seosiokyongsan fermented soap can effectively reduce especially the large size of pores.
