Pycnogenol extracted from pine bark is a component with great antibacterial activity and antioxidant effect. It is applied as a natural anti-inflammatory agent with various medical effects including anti-inflammatory effects, regulation of blood pressure, regulation of the immune system, and inhibition of cancer cell growth. However, research related to cosmetics is limited. Therefore, in this study, the effect of Pycnogenol on the skin was studied through a clinical approach. Changes in skin condition were observed after using cosmetics with Pycnogenol and without Pycnogenol for 6 weeks for 10 clinicians in each group. We observed the effect of pore reduction, wrinkle reduction around eyes, a decrease of the number and angle of loose pores, and reduction of pigmentation. Therefore, cosmetics containing Pycnogenol have the effect of improving skin problems of aging skin.

인삼 유래 나노 엑소좀 화장품 성분이 30~50대 여성의 피부 상태 개선에 미치는 효과

세포외소체 엑소좀은 다양한 세포 유래 물질들이 포함되어 있어 다른 세포에 정보 전달을 통해 세포 대사에 영향을 주는 독특한 효능이 있어 질병 진단 및 치료제로써 가능성을 제시하였다. 최근에는 엑소좀이 생명공학과 제약 외에 화장품 소재로서 활용되고 있으며 다양한 종류의 식물유래 엑소좀에 대한 연구가 진행되고 있다. 하지만 화장품 원료서의 엑소좀 연구가 주로 세포실험을 통해 이뤄지고 화장품 임상실험을 통한 효능 효과 연구는 미미한 실정이다. 그러므로 본 연구에서는 인삼 엑소좀 성분을 화장품 임상실험을 통해 피부에 미치는 효과를 연구하고자 하였다. 화장품 임상실험에는 실험군 11명, 대조군 11명 22명의 연구대상자 참여하였으며, 실험군은 엑소좀 0.1% 함유한 화장품 3종을 대조군은 엑소좀 무첨가 화장품 3종을 매일 아침과 저녁 6주 동안 사용하게 한 후 피부 상태변화를 분석하였다. 대조군에서는 유의미한 피부 상태 변화가 나타나지 않았다. 반면에 엑소좀을 함유하는 화장품을 사용한 실험군은 모공, 주름, 피부거칠기가 감소하였으며 피부 수분과 밝기가 증가하였다. 반면에 UV색소침착과 홍조에서는 변화가 나타나지 않았다. 그러므로 엑소좀 화장품 성분은 피부의 주름 감소와 모공 감소 등 노화 피부 상태개선에 도움을 주며, 피부의 수분증가와 피부결을 개선하고 피부를 밝아지게 하는 효과가 있어 화장품 성분으로 활용가치가 있다고 생각된다. Exosomes, extracellular vesicles, contain a variety substances derived from cells. They influence cell metabolism by delivering information to other cells. Hence, this study proposes their potential for use in diagnosing or treating diseases. Recently, the bio-vesicles have been utilized not only as cosmetic ingredients but also in pharmaceutical and bioengineering applications. Concurrently, studies have focused on exosomes derived from diverse types of plants. However, it has proven challenging to find studies that specifically investigate the effects of exosomes as cosmetic materials through clinical trials. Under these circumstances, this study sought to examine the impact of ginseng-derived exosomes on human skin through clinical trials. A total of 22 individuals participated in the research study, with 11 participants assigned to each control and experimental group, respectively. The experimental group received three different cosmetics containing 0.1% exosomes, while the control group was provided with three cosmetics devoid of any exosomes. These were administered in the morning and evening daily over a period of 6 weeks. Subsequently, changes in skin conditions were analyzed, and the results revealed the following findings: In the control group, no significant skin changes were observed. Conversely, in the experimental group, improvements were noted in pore conditions, wrinkles, and skin coarseness. Additionally, enhancements were observed in skin moisture and brightness. In contrast, no changes were found in UV-induced pigmentation and skin redness. Consequently, it appears that exosomes are valuable as cosmetic ingredients, as they have demonstrated effectiveness in reducing wrinkles, tightening pores, improving skin moisture and texture, and brightening the skin.

As a research for the effect of aesthetic meridian massage to mood state, the purpose of this study is to present scientific proof of its effect and to provide basic material that aids in utilizing aesthetic meridian massage as a management method of health maintenance and health improvement. From September 8th to September 12th 2008, a random sample of female students from the Cosmetics Departments of S College were selected for the research; 20 people were placed in a test group and 20 people were placed in a control group, and a study was carried out through a nonequivalent control-group pretest-post test design. To measure stress relief level, 65 items of the Profiles of Mood States(POMS) were used. For the test, participants in the test wrote down the POMS on the paper, and they were given aesthetic meridian massage for 20 minutes while they were sitting on the chairs. The control group was allowed to rest for the same period of time with the same posture. Ten minutes later, they wrote the POMS again, and the results from the analysis are as follows. After comparing pre-test and post-test levels in Total Mood Disturbance(TMD) of the test group and control group using POMS, the test group showed a decline by 74.47%(3.901) and the control group showed a decline by 7.698%(0.387). The test groups showed a significantly larger decline statistically(t=-12,375, p=0.000). In comparison between the pre-test and post-test POMS by specific questions within the test group, the value p was smaller than 0.05, showing that they significantly decreased statistically. In comparison between the pre-test and post-test POMS by specific questions within the control group, unlike the test group, significant difference appeared only in the items of tension and fatigue. For the items of depression, anger and confusion, the value p was bigger than 0.05, showing no significant difference between the pre-test and post-test. The results from the test show that aesthetic meridian massage relieves stress created in daily life and has a positive effect in altering overall mood conditions. Therefore, it can be concluded that the aesthetic meridian massage can be used as an effective massage method for the health management of modern people.

The purpose of the study is to identify the relationship among the variables related the high school students` achievement goal orientation, the use of cognitive strategies and their perceived understanding of mathematics, and verify the path model of causal relationship among those variables by applying the resources from the Korea Education Longitudinal Study 2005(Ⅳ) (KELS:2005(Ⅳ)) conducted by the Korean Educational Development Institute. Based on the theoretical rationale, the researchers hypothesized that the two achievement goal orientation and the three cognitive strategies directly influence upon the perceived understanding as well as that mastery goal influences on the perceived understanding via the rehearsal which is one of the cognitive strategies and performance goal influences on the perceived understanding by way of coding which is also one of the cognitive strategies. The researchers also hypothesized a path model including the metacognition as a intermediate variable for rehearsal and coding strategies. 5,910 samples of the high school students` data were analyzed using EQS version 6.0 and the main results of the path analysis are as follows; Firstly, it was shown that the two achievement goal orientation, the three cognitive strategies and the perceived understanding were significantly correlated each other in whole pairs. Secondly, an appropriate path model was found with the addition of a path on the hypothetical path model through the LM test. Thirdly and the last, it was shown that there were significant effects and related power value on each path toward rehearsal, coding, metacognition and the perceived understanding of mathematics.

Im Prozess der Uberlieferung sind gewisse Transformationen unvermeidlich. Auch bei der schriftlichen Uberlieferung der Marchen. In dieser Arbeit handelt sich hauptsachlich um die Sammlung und Bearbeitung der deutschen Marchen von Bruder Grimm, dessen <Kinder- und Hausmarchen> als “eine Schnittstelle fur vielerlei Entwicklungen im volksliterarischen und literarhistorischen Bereich, in denen viele vorgangige Tendenzen und Probleme kulminieren und die durch ihre Prioritat und ihren unbestrittenen Vorbildcharakter die literarische Volkskunde bis heute in hohem Maße beinflussen”(Rolleke) geschatzt werden. Sie willen deutsche Marchen sammeln, weil sie denken, dass in Volksmarchen “lauter urdeutscher Mythus, den man fur verloren gehalten” liegt, und beim Sammeln halten sie “Treue und Wahrheit” fur wichtig. Aber viele Forschungen uber Grimms KHM diskutieren die Sache der Volkstumlichkeit und Treue der KHM. Trotzdem machen Grimms’ bestandige asthetische Bearbeitungen bis zur letzte Ausgabe die KHM zum Vorbild bei der Sammlung und Bearbeitung der Marchen als Buchmarchen. In Korea werden einige ihre Marchen schon in der 1910er Jahre in der Form der Adaptation vorgestellt, wo in anderer Weise zeigt, dass “sich die Marchen in dem Fortgange der Zeit bestandig neu erzeugt”, wie Grimms sagen.
