This study was accomplished to investigate the ultrastructure of mucous glands in dorsal skin of frog (Rana catesbeiana) by means of scanning and transmission electron microscopes. The dorsal skin of Rana catesbeiana is composed of epidermis and dermis. The cutaneous mucous glands consist of inner glandular epithelial cells and outer myoepithelial cells. Glandular epithelial cells are divided into four types by the microscopic ultrastructure; ER-rich cell, round secretory granule-containing cell, foam-like granule mass-containing cell, mitochondria-rich cell. Myoepithelial cell has a long elliptical nucleus and filled with fibrous materials in the cytoplasm. As a result of scanning microscopic observation, the surface of dorsal skin is covered with cutaneous protrusions. The opening sites of the mucous glands are irregularly distributed in dorsal skin.

Statement of problem : Use of fiber composite technology as well as development of nonmetal implant prosthesis solved many problems due to metal alloy substructure such as corrosion. toxicity, difficult casting, expensiveness and esthetic limit. After clinical and laboratory test, we could find out that fiber-reinforced composite prostheses have good mechanical properties and FRC can make metal-free implant prostheses successful. Purpose : The purpose of this study is to evaluate the flexural strength of implant fixed prosthesis using fiber reinforced composite. Material and methods : 2-implant fixture were placed in second premolar and second molar area in edentulous mandibular model, and their abutments were placed, and bridge prostheses using gold, PFG, Tescera, and Targis Vectris were fabricated. Tescera was made in 5 different designs with different supplements. Group I was composed by 3 bars with diameter 1.0mm and 5 meshes, 2 bars and 5 meshes for Group II, 1 bar and 5 meshes for Group III, and only 5 meshes were used for Group IV. And Group V is composed by only 3 bars. Resin (Tescera) facing was made to buccal part of pontic of gold bridge. All of gold and PFG bridges were made on one model, 5 Targis Vectris bridges were also made on one model, and 25 Tescera bridges were. made on 3 models. Each bridge was attached to the test model by temporary cement and shallow depression was formed near central fossa of the bridge pontic to let 5 mm metal ball not move. Flexual strength was marked in graph by INSTRON. Results : The results of the study are as follows. The initial crack strength was the highest on PFG. and in order of gold bridge Tescera I, Tescera II, Targis vectris, Tescera IV, Tescera III, and Tescera V. The maximum strength was the highest on gold bridge, and in order of PFG, Tescera I, Tescera IV Tescera II, Targis vectris, Tescera III, and Tescera V. Conculsions : The following conclusions were drawn from the results of this study. 1. Flextural strength of implant prosthesis using fiber reinforced composite was higher than average posterior occlusal force. 2. In initial crack strength, Tescera I was stronger than Tescera V, and weaker than PFG. 3. Kinds and number of auxillary components had an effect on maximum strength, and maximum strength was increased as number of auxillary components increased. 4 Maximum strength of Tescera I was higher than Targis vectris, and lower than PFG.

내러티브 사고에 기초한 스토리텔링 생물학습프로그램 개발

강경희(Kyung-hee Kang) 성신여자대학교 교육문제연구소 2011 교육연구 Vol.50 No.-

내러티브 사고가 배제된 기존의 과학교육은 학습 내용에 대한 맥락적 이해를 어렵게 했다. 따라서 이 연구의 목적은 내러티브 사고에 기초한 스토리텔링 학습프로그램을 개발하기 위한 것이다. 이 연구에서는 교육과정 분석을 바탕으로 중학교 학생들을 대상으로 하는 12종의 스토리텔링 자료가 개발되었다. 학습프로그램은 퀘스트 스토리텔링으로 구성되었다. 각 퀘스트를 해결하는 과정에서 조사, 토의, 실험 등의 다양한 학습활동이 이루어지도록 설계했다. 스토리텔링 학습프로그램의 개발과 적용은 학습자들의 내러티브 사고를 신장시키는 데 기여할 것으로 기대된다. The science education which excluded narrative thinking has restricted contextual understanding about learning contents. Therefore, the purpose of this research is to develop storytelling learning program on the basis of narrative thinking. In this study, we developed twelve kinds of storytelling materials for middle school students on the basis of curriculum analysis. The learning program was composed of quest storytelling. We designed various learning activities which included investigation, discussion, and experiment in the process of solving each quest. The development and application of storytelling learning program will contribute to expanding learners’ narrative thinking.

Streptococcus mutans의 acid stress에 따른 유전자 발현변화 분석

강경희(Kang, Kyung-Hee) 한국산학기술학회 2010 한국산학기술학회 학술대회 Vol.- No.-

본 논문에서는 한국인 아동의 우식치아로부터 S. mutans를 분리하고, acid stress하에서 분리한 S. mutans의 유전자의 발현의 변화를 분석하고자 하였다. 치아우식증의 주요한 요소로 작용하는 치태형성에 기여하는 glucan 및 fructan 합성에 관여하는 세포내 효소인 glucosyltransferase, glucosyltransferase, glucosyltransferase 및 fructosyltransferase의 발현량의 변화를 확인한 결과, lactic acid를 처리하지 않은 control의 경우보다 16배에서 3배까지 감소한 것을 확인할 수 있었다. Amino acid ABC transporter, adenylate kinase, fructokinase, 40k cell wall protein precursor에서는 모두 유전자의 발현량이 현저히 증가한 것을 볼 수 있었다. 이들 유전자는 acid stress에 관여하는 특이적 유전자로 추정된다,
