In this study, core technologies applied to the beauty industry (hair, makeup, skin care, nail) in the era of the 4th industrial revolution and the transition of industrial paradigm of literature review was performed. Based on this, analysis and prediction of future trends were performed through case analysis of ICT convergence applied to the beauty industry. As a result, it could be confirmed that these core technologies are progressing in the direction of improving the value of the services provided in the past through convergence. Therefore, it was possible to confirm through case analysis that the direction of the beauty industry was changing from the existing function-oriented professional service concept to customer-centered personalization, prediction, prevention, and participation. This study expands the scope of research on convergence with core technologies of the 4th industrial revolution at the conventional corporate level and expands it to the beauty industry to analyze the future through convergence with core technologies from the beauty business perspective. There are implications for predicting the direction of In addition, by categorizing the beauty industry into four types (hair, makeup, skin care, and nail), specific future directions for each sub-area are presented, thereby presenting practical implications that can be immediately applied to the workplace.

이 연구의 목적은 대장균 분자 샤페론 GroEL의 시험관 내 단백질 접힘에 있어서 반응온도의 영향과 보조샤페론의 필요 여부를 자발적 재접힘이 가능한 온도와 그렇지 않은 온도조건에서 조사하는 것이다. 여러 조건하에서 GroEL에 의한 두 가지 기질 단백질의 재접힘을 반응속도론적으로 조사하기 위하여 GroEL에 의한 단백질 침전생성억제와 변성된 단백질의 재접힘을 광범위하게 조사하였다. 자발적 재접힘이 가능하지 않은 $37^{\circ}C$에서는 ATP와 완전한 GroEL 시스템이 변성된 폴리펩티드의 재접힘을 위하여 필요하다는 것을 확인하였다. 하지만, 자발적 재접힘이 가능한 낮은 온도에서는 자발적 재접힘과 샤페론 의존적 단백질 재접힘이 서로 경쟁하는 것을 알 수 있었다. 따라서 GroEL은 변성된 폴리펩티드의 자발적 접힘 경로를 더 효율적인 단백질 재접힘 경로인 샤페론 의존적 단백질 재접힘 경로로 유도하는 것으로 보인다. The goal of this study is to investigate effects of temperature and co-chaperonin requirement for in vitro protein refolding assisted by E. coli chaperone GroEL under permissive and nonpermissive temperature conditions. In vitro protein refolding of two denatured proteins was kinetically investigated under several conditions in the presence of GroEL. Effects of temperature and GroES-requirement on the process of prevention of protein aggregation and refolding of denatured protein were extensively monitored. We have found that E. coli GroEL chaperone system along with ATP is required for invitro refolding of unfolded polypeptide under nonpermissive temperature of $37^{\circ}C$. However, under permissive condition spontaneous refolding can occur due to lower temperature, which can competes with chaperone-mediated protein refolding via GroEL chaperone system. Thus, GroEL seemed to divert spontaneous refolding pathway of unfolded polypeptide toward chaperone-assisted refolding pathway, which is more efficient protein refolding pathway.

본 연구에서는 춘천 지역에서 재배되고 있는 메밀의 부위별(종피, 종자, 줄기) 추출물을 이용하여 MTT assay 항산화 효능(수퍼옥사이드 라디칼, 하이드록실 라디칼 소거능), rutin과 phytic acid에 대한 함량 측정, 대표적인 중금속 중의 하나인 카드뮴에 대한 세포 수준에서 방어 효능을 평가하였고, 이들 자료를 토대로 주된 식품재료로 쓰이고 있는 메밀을 기능성 화장품의 소재로써 개발할 수 있는 가능성을 조사하여 보았다. HaCaT 세포와 B16F10 세포를 이용한 세포 독성 실험에서는 각 추출물 100 ㎍/mL의 농도 범위에서는 독성이 없는 것으로 나타났다. 수퍼옥사이드 라디칼에 대한 소거능은 종피>줄기>종자 추출물 순이었으며, 종피나 줄기는 거의 비슷한 수준의 효능을 보여 주었으며, 항산화 효능에 관여하는 주요 물질중의 하나인 rutin은 줄기 부위에 가장 많이 함유하고 있었다. 하이드록실 라디칼에 대한 소거능은 각 추출물 모두 거의 없는 것을 확인할 수 있었다. 중금속에 대한 chelate 물질로 알려진 phytic acid는 rutin처럼 줄기 부위에 높은 농도로 함유되어 있었다. 카드뮴에 대한 독성은 HaCaT 세포에서 50 μM의 농도일 때 50% 정도의 치사율을 보였으며, 카드뮴을 추출물과 같이 처리하였을 때는 카드뮴의 독성에 대해 약 10% 정도 방어 효과를 나타냈다. Confocal laser scanning microscope를 이용하여 카드뮴에 의한 세포내 활성산소종의 생성을 확인하였고. 생성된 활성 산소 종에 대한 방어 효능은 줄기추출물에서 가장 우수한 것을 확인하였다. In the present study, the Chuncheon buckwheat extracts prepared from its seed coats, seeds and stems were used to determine anti-oxidative effects, the content of rutin and phytic acid, and the protective role against cadmium at the cellular level. futhermore, it was evaluated whether the buckwheat, mainly known as a healthy food source, might be applicable to functional cosmetics. Up to 100 ㎍/mL of the extract was not toxic in HaCaT and B16F10 cell lines using MTT assay. The anti-oxidative capacity of superoxide radicals was shown in seed coats extracts > stem extracts=seed extracts. Although its content of rutin, known as one of effective anti-oxidants, mainly exists in the stem, any extract did not eliminate hydroxyl radicals. Phytic acid, known as a heavy metal-chelate agent, was highly concentrated in the stem. The Chuncheon buckwheat extract had 10% protective effect against the treatment of 50 μM cadmium at which 50% of HaCaT cells survived. Confocal laser scanning microscope revealed the intracellular generation of reactive oxygen species (ROS) by cadmium treatment. Finally, we identified that the stem extract had the most protective effect on the elimination of ROS.

장경진 韓國舞踊敎育學會 2002 韓國舞踊敎育學會誌 Vol.13 No.1

The purpose of this study is to examine the influence of dance sports on children's subjective mood change. For this study, 64 primary students were selected at random and were allocated to the experiment group and the control group by 32 each. For 40 minutes, the experiment group performed dance sports whereas the control group played with table tennis balls and rakets. The pretest and post-test were conducted by using the Profile of Mood States. According to the results of repetition measurement and dispersion analysis, it was found that there was a significant difference in the experiment group and the control group. The dance sports group showed lower values than the other group in tension (P<.015), depression (P<.021), anger (P<.032), and confusion (P<.008). On the other hand, the dance sports group showed a higher value in energy (P<.002) and for fatigue, both groups showed higher values. These results proved that dance sports have positive effects on children's subjective mood change.

Under the current dance educational system, it is difficult to expect a dance from to emerge which would satisfy the educational needs of the future society in its seeking for creativity. In order to establish the necessary position for a dance education fromat which it aimed at the 2000's, current training courses, dance instructors, associated educational system and facilities have been analyzed, and the following conciusions derived. Dance, with respect to training course, must be an independently taught and marked subject in primary, middle and high schools and, to improve the quality of dance instruction dance instructors must be properly qualified and certified, and through the appontment of teachers in charge of dance to positions as dance choreographers, the entire system surrounding and driving dance must improve. In addition, school dance facilities must be expanded by providing more dance practice and performance rooms and y installing such facilities as T.V and VTR equipment. Only when such conditions are satisfied, future dance education be expected to receive due recognition for its importance within the realm of true higher education.

이사도라 던컨의 무용사상과 그 현대적 의의

As the 20th century sets in, beauty of dance was becoming more formalized and excessively specialized. Attempts to get not of dissatisfaction with this tendency brought about the birth of modern dance which tried to express the stream of movements by using all parts of body, fully free from forms techniques, music, shoes and dresses. Thanks to its unique characteristic of making dance part of a human life for children, adults, laymen and professional dancers, modern dance has had immense effects on the field of dance as an education-purposed dance. The root of the so-called modern dance must be found in the history of American modern dance, and the origin of modern dance must be attributed to Isadora Duncan's ideology on dance. To understand Duncan's ideology on dance, this study tried to investigate her true character based on her autobiography entitled "MY LIFE". In addition, this study tried to explore the origin of her dance and its meaning by understanding Duncan herself and her ideology In order to illuminate her marvelous traces and brilliant lessons for today's dance development, this study drew the following conclusion from its findings about her life and ideology. Duncan suggested possibility of dance to develop into an independent art free from music, literature, or fine art by discovering the intrinsic meaning of physical movements. She also expanded the scape of expression abilities of dance by discovering the world of mind. Since Duncan's dance is characterized as expression of human emotions, she should be seen as the pioneer of our today's 'modern dance'. In addition, she was not only the founder of modern dance having systematic techniques but also a great revolutionary who awoke the then dance world by introducing a new choreography. From the perspective of dance history, Duncan's ideology on dance provided the basis to construct the underlying principle of 'modern dance'. Based on this conclusion, this study made the following suggestions, first, under the lifetime education philosophy, dance education should be restructured, escaping from the current technique-based education for fostering professional dancers, to introduce a new concept that dance is part of routine human life, second, since Duncan's spirit of dance based on soul expression through natural movements, not on techniques, casts a great meaning to modern dance education, the mission of modern dancers, choreographers, and educators is to inherit Duncan's spirit by keeping and developing a living dance.
