This study investigated the changes of hair cuticle shape by means of scanning Electron Microscope(SEM) after permanent waving and bleaching, according to different types of chemicals(perm, bleach)and of temperatures(25℃, 50℃). The subjects were Korean students in their twenties who did not go on a diet, took no drugs, and had virgin hair. Virgin hair remained dense without being splayed off the scale, overlapped in a regular basis, and clear of the boundary between scales. But, the scale of hair cuticle had been splayed, separated, and lost by permanent waving and bleaching with hair chemicals. The hair cuticle that was permanent waved at 25℃ once and three times showed almost virgin hair, and the cuticle of hair permanent waved at 50℃ once was just a little splayed, so it seemed that perm treatment frequency and the permanent wave lotion with low pH were not major factors at low temperature. However, repeating the performance of bleaching, though at low temperature, was more major harmful factor than high temperature. This result reveals that a chemical of pH 11.0 for bleach damages hair severely leaving splayed and cracked in the whole hair, and maker\s column wrinkled scales regardless of temperature.

The purpose of this study was to investigate the positional changes of the mandibular condyles after orthognathic surgery in patients with severe skeletal Class Ⅲ malocclusion. This study was based on 21 patients who had received bilateral sagittal split osteotomy for mandibular setback. Among them 14 were fixated non-rigidly(W group), and 7 were fixated rigidly(R group). After submental vertex view analysis, each subject was given the T.M.J Tomogram in both centric occlusion and centric relation immediate before. 4~6 weeks after and more than 6 months after surgery. The anteroposterior and vertical changes between each time interval were measured and analyzed statistically. Following results were obtained. 1. There was no signifficant difference between right and left condyles in their anteroposterior and vertical changes of the condylar position. 2. In anteroposterior changes of condylar position of the wire fixation group, the condyles were moved anteriorly 4-6 weeks after surgery, and then the pattern of reestablishment to their preoperative position was observed more than 6 months after surgery. In the rigid fixation group, there was no signifficant difference in any observation periods of centric occlusion and centric relation. 3. In vertical changes of condylar position of the wire fixation group, the condyles were moved inferiorly 4-6 weeks after surgery, and then the pattern of reestablishment to their preoperative position was observed more than 6 months after surgery. In the rigid fixation group, the condyles were moved inferiorly 4-6 weeks after surgery, and then the pattern of reestablishment to their preoperative position was observed more than 6 months after surgery in centric occlusion only.

배선향,윤수홍,이도영 한국위생과학회 2002 한국위생과학회지 Vol.8 No.2

펌 및 탈색 시 모발 손상을 줄이기 위한 기초자료를 제공하기 위해 20대 여대생의 건강한 모발을 펌 및 탈색을 하면서 전자 현미경으로 그 형태적 변화를 조사한 결과는 다음과 같았다. 자연 모발은 굵기가 60~80 ㎛인 비교적 가는 건강한 직모로 나타났다. 모표피(hair cuticle)의 비늘은 벌어지거나 벗겨짐이 서로 밀착되어 있었으며, 비늘의 겹쳐진 폭이 규칙적이었다. 또한 비늘 사이의 경계가 뚜렷하였고, 비늘의 표면은 매끈하였다. 25 ℃에서 1회 펌을 한 모발의 경우 한 부위에서만 비늘의 가장자리가 벌어졌을 뿐 다른 부위에서는 비늘의 벌어짐이 없이 밀착된 상태로 나타났다. 25 ℃에서 3회 펌을 한 모발의 경우에는 네 부위에서 비늘의 가장자리가 약간 더 벌어졌으나 25 ℃에서 1회 펌을 한 모방의 손상 정도와 큰 차이가 없었다. 50 ℃에서 1회 펌을 한 모발은 전체부위에서 비늘이 약간씩 벌어졌다. 25 ℃에서 3회 펌을 한 모발에 비해 비늘의 형태가 더 손상된 형태로 나타났다. 50 ℃에서 3회 펌을 시술한 모발은 심하게 손상되었다. 약 40 %의 비늘 가장자리가 벌어졌고, 약 10 %의 비늘은 미세한 주름이 생겼으며, 모발의 한 부위에는 구멍이 생겼다. 25 ℃에서 1회 탈색한 모발의 경우 전체에서 비늘이 벌어졌으며, 두 부위에서는 비늘이 탈락되어 비늘의 간격이 불규칙하였고, 전체 모발 중에서 약 15 %의 비늘에 세로 주름이 나타났다. 25 ℃에서 3회 탈색한 경우에는 모발 전체에서 비늘이 용해되어 두꺼워졌고, 모표피의 문리가 일정하지 않았으며, 모발의 몇몇 부위에 구멍이 생겼다. 50 ℃에서 1회 탈색한 경우 90 % 이상의 비늘이 벌어졌고, 약 25 %의 비늘에 뚜렷한 세로 주름이 생겼으며, 한 장의 비늘에 작은 구멍이 나타났다. 50 ℃에서 3회 탈색한 경우에는 모발 전체에서 모표피의 문리가 없어졌고, 용해된 비늘이 뭉쳐 있었으며, 또한 작은 구멍들이 여러 부위에 생겼다. 펌을 한 경우보다 탈색한 경우 모방의 손상 정도가 큰 것으로 나타났으며, 가장 손상의 정도가 큰 것은 50 ℃에서 3회 탈색한 경우로 나타났다. The morphological changes were investigated for the purpose of suggest the basic information to lesson hair damages by perm and decoloration. Women hairs were permed and decolored one time and three times at different temperature(25 ℃, 50 ℃), respectively. Then, the hairs were photographed with scanning electron microscope. The virgin hairs, which were not permed and not decolored, were morphologically healthy. Hair cuticle scales were not splayed and overlapped regularly. Perm hairs, which were treated one time at 25 ℃, were relatively healthy though one scale of hair cuticle was splayed. and, on the occasion of perm hairs treated three times at 25 ℃, four scales of hair cuticle were splayed. Hairs, which were permed at 50 ℃, were more damaged than those which permed at 25 ℃. Hair scales, which were permed at 50 ℃, were almost splayed. On the occasion of perm hairs treated three times at 50 ℃, 10 percentages of hair scales were wrinkled, and one scale was holed. Hair scales, which were decolored one time at 25 ℃ were almost splayed, and 15 percentages of hair scales were wrinkled. Hair scales, which were decolored three times at 25 ℃, were almost melted and thickened. 90 percentages of hair scales, which were decolored one time at 50 ℃, were splayed, and 25 percentages of hair scales were wrinkled. On the occasion of decoloration hairs treated three times at 50 ℃, the boundaries between scales were almost disappeared, and hair scales were melted and were agglomerated. Hairs, which were decolored, were more morphologically damaged than those which premed.

본 연구는 검은비늘버섯((CBPM-6호)의 선도유지 효과를 알아보기 위해 포장재(Wrap, PE, PP, AF) 및 저장온도(1℃, 3℃, 6℃)을 달리하여 18일간 결과를 다음과 같다. 저장기간 중 포장재별 중량 감모율은 랩 포장시 1℃에서 18일 후 3.17%이었으나, AF필름에서는 1.08%의 낮은 중량 감모율을 나타내었다. 색도는 저장기간이 연장될수록 명도와 황색도는 약간 증가하는 반면 랩 표장에서는 감소하는 경향을 나타내었다. 버섯 저장 전 색깔은 랩 포장에서는 3일, PE, PP, AF포장지에서는 18일까지 유지되었다. 경도는 저장온도가 높을수록 낮아지는 경향이었으며 1℃에서 저장할 때 AF 밀봉 저장이 경도의 변화가 가장 적은 것으로 나타났다. 신선도는 1℃ 저장시 신선도 8을 기준으로 랩 포장은 3일, PE 밀봉은 6일, PP 밀봉은 9일, AF 밀봉으로 15일간 저장시 상품성을 유지할 수 있다. This study was carried out to develop storage method for the keeping freshness with various packing film(Wrap, PE, PP and AF and storage temperature(1, 3 and 6℃) of Pholiota adiposa(CBPM-no6) mushroom. The rate of weight loss packed with Wrap film was 3.17%, but AF film was 1.08% after 18days. As the storage periods, lightness and yellowness of mushroom packed with PE, PP and AF were slighty increased, while Wrap film was decreased. The color of original raw mushroom preserved 3days using Wrap film and 18 dyas using PE, PP and AF. As storage temperature high, the rigidity of mushroom decreased. Rigidity of mushroom packed with AF film was less change compared with the other film. Freshness degree of mushroom(refer to Minamide method) could preserve for 3days using Wrap, 6 days using PE, 9 days using PP and 15days using AF film at 1℃.

Cathepsin B Inhibitor E-64 Enhances Developmental Rate and Reduces Apoptosis in Porcine Parthenotes

Seon-Hyang Kim,Ming-Hui Zhao,Jung-Woo Kwon,Shuang Liang,Chang-Eun Park,Nam-Hyung Kim,Xiang-Shun Cui 한국동물생명공학회(구 한국동물번식학회) 2014 Reproductive & Developmental Biology(Supplement) Vol.38 No.2s

Cathepsin B, a lysosomal cysteine protease of the papain family, has recently been implicated in quality and developmental competence of bovine preimplantation embryos. In this study, to determine whether inhibition of Cathepsin B activity could improve oocyte maturation and early embryo developmental competence in porcine, we added E-64, an inhibitor of Cathepsin B, into the in vitro maturation and culture media. Both mRNA and protein expression were no differences in germinal vesicle (GV) stage oocytes between good and poor quality from the morphology. Even activity of Cathepsin B is high in good quality GV stage oocytes, E-64 did not enhance in vitro maturation of porcine oocyte. However, I nM E-64 significantly (p<0.05) increased blastocyst formation and cell numbers. Inhibition of Cathepsin B activity did not alter mitochondrial membrane potential, copy numbers and ATP contents. But, E-64 significantly (p<0.05) reduced mitochondrial release of cytochrome c, finally decreased mRNA expression of Caspase 3 and Caspase 9, resulted in reduction of apoptotic index in porcine blastocysts. Collectively, these observations suggest that Inhibition of Cathepsin B activity enhanced developmental competence and reduced apoptosis through protecting against cytochrome C release from mitochondria in porcine parthenotes.

박선향(Seon-Hyang Park) 한국산학기술학회 2023 한국산학기술학회논문지 Vol.24 No.10

본 연구는 교수학습센터에서 운영하는 비교과 프로그램의 통합적 성과평가 모형을 설계하여 실증적 자료로써 검증해 보는 데 그 목적을 두었다. 이를 위해 프로그램의 성과를 객관적 · 주관적 성과로 나누어 효율성을 기준으로 객관적 성과평가를, 프로그램의 질적 만족도를 기준으로 주관적 성과평가를 실시하였다. 그리고 객관적 성과평가와 주관적 성과평가를 통합하기 위해 IPA 분석을 하였다. 이 모형을 통해 프로그램별 효율성이 높고 질적 만족도가 높아 바람직한 성과를 낸 프로그램이 확인되었으며, 반면 효율성이 낮고 질적 만족도가 낮아 우선순위가 가장 낮기에 프로그램 운영방향을 재고할 프로그램이 확인되었다. 이로써 통합적 성과평가 모형은 프로그램별 성과 비교 및 바람직한 개선의 방향에 대한 시사점을 발견할 수 있게 한다는 점에서 그 활용가치를 기대할 수 있다. The purpose of this study was to design an integrated performance evaluation model for extracurricular programs operated by the Center for Teaching and Learning and verify it with empirical data. For this purpose, the performance of each program was divided into objective and subjective performance. The objective performance evaluation was conducted based on efficiency, and the subjective performance evaluation was based on the qualitative satisfaction with the program. An importance performance analysis(IPA) was carried out to integrate the objective and subjective performance evaluation. Programs with high efficiency and high qualitative satisfaction that produced desirable outcomes were identified, while programs with low efficiency and low qualitative satisfaction were designated as having the lowest priority, requiring reconsideration of the direction of program operation. The integrated performance evaluation model would be valuable as it enables a program-wise comparison of performance and the discovery of desirable directions for improvement.
