The excessive initial corrosion rate of Mg is a critical limitation in the clinical application of biodegradable Mg implantsbecause the device loses its fi xation strength before the fractured bone heals. This study suggests a new approach to overcomethis hurdle by accelerating tissue regeneration instead of delaying the implant biodegradation. As angiogenesis is anessential process in early bone regeneration, a Mg implant coated with electrospun nanofi bers containing nitric oxide (NO),which physiologically promotes angiogenesis, is designed. The integrated device enables adjustable amounts of NO to bestored on the NO donor-conjugated nanofi ber coating, stably delivered, and released to the fractured bone tissue near theimplanted sites. An in vitro corrosion test reveals no adverse eff ect of the released NO on the corrosion behavior of the Mgimplant. Simultaneously, the optimal concentration level of NO released from the implant signifi cantly enhances tube networkformation of human umbilical vein endothelial cells without any cytotoxicity problem. This indicates that angiogenesis canbe accelerated by combining NO-releasing nanofi bers with a Mg implant. With its proven feasibility, the proposed approachcould be a novel solution for the initial stability problem of biodegradable Mg implants, leading to successful bone fi xation.

This research with 40 hearing impaired children was performed to find out the characteristics of the phonological processes for each age, hearing loss degree and aided threshold degree through the transcriptions. The phonological processes. of hearing impaired children are similar to those of normal children with a peculiar type of patterns in phonological processes. The results show that: (1) Between 5 and 6 year old groups the phonological processes were significantly different in palatal backing, glottal replacement and frication; between 6 and 7 year old groups the phonological processes were significantly different in velar fronting, labialization, alveolization and labial assimilation; between 7 and 8 year old groups the phonological processes, labialization, alveolization and alveolar assimilation, however 8 year old group showed more phonological processes than 7 year old group. (2) Between moderately-severe and severe hearing impaired groups, phonological processes were significantly different in the omissions of postvocalic, nasal and velar, stopping and stop assimilation. The differences of severe and profound groups were not found at all. (3) Aided hearing thresholds did not show any significant difference.

서영진,이민웅,한영환 동국대학교 경주대학 1999 東國論集 Vol.18 No.-

목질진흙버섯(Phellinus linteus) 배양시 높은 빈도로 오염되는 진균을 분리하여 형태적 특징에 따라 Monilia sitophila로 동정하였고, Monilia sitophila DGUM 7000으로 명명하였다. M. sitophila DGUM 7000의 균사생장을 위한 최적 온도 및 pH는 각각 37℃와 7.0이었다. MCA배지를 기본배지로 탄소원 이용성 실험에서 단당류, 이당류 및 다당류로 xylose, lactose, CMC를 사용하였을 때 가장 우수한 균사생장을 나타내었다. 유기산으로 gluconic acid를 MCA배지에 첨가시 균사생장이 촉진되었으나, oxalic acid를 첨가하였을 때 생장이 억제되었다. Yeast extract가 포함된 배지에서 우수한 균사생장을 보여주었다. 유기질소원으로 tyrosine 및 leucine이 균사생장에 가장 우수한 아미노산이었다. 무기질소원으로 sodium nitrate가 가장 우수하였으나, ammonium molybdate 사용시 생육이 억제되었다. 사용된 모든 인산원에서 우수한 균사 생장을 나타내었다. 항진균제 thiabendazole, benomyl을 각각 1.0 및 0.2 ㎎/L 농도로 첨가하였을 때 목질진흙버섯의 균사생장에 큰 영향은 없었으나, M. sitophila DGUM 7000 오염균의 균사생장은 현저하게 억제되었다. 이 결과는 thiabendazole 과 benomyl이 목질진흙버섯 배양시 M. sitophila 오염균 방제를 위한 항진균제로의 사용 가능성을 제시하였다. The red fungus was isolated from the contaminated culture bottle of Phellinus linteus. It was identified as Monilia sitophila based on morphological characteristics and named as Monilia sitophila DGUM 7000. The optimal temperature and pH for the mycelial growth of M. sitophila DGUM 7000 were 37℃ and 7.0, respectively. When xylose, lactose and CMC were supplemented in MCA media as a mono-, di- and polysaccharide, mycelial growth of M. sitophila were most effective. As a organic acid, gluconic acid enhanced the mycelial growth. However oxalic acid inhibited the mycelial growth. The mycelial growth of M. sitophila DGUM 7000 was enhanced by addition of yeast extract. As a organic nitrogen source, tyrosine and leucine were very effective amino acids. As a source of inorganic nitrogen, sodium nitrate was the best. However, ammonium molybdate inhibited the mycelial growth. All the sources of phosphate tested showed good mycelial growth. The addition of 1.0 ㎎/L of thiabendazole or 0.2 ㎎/L of benomyl inhibited the mycelial growth of M. sitophila DGUM 7000, but did not those of P. linteus. This result suggests that thiabendazole and benomyl control the growth of contaminant M. sitophila and could be used as a antifungal agent for the cultivation of P. linteus.

창의성 관점에서 본 제 7차 초등 수학과 교육과정 : 규칙성과 함수를 중심으로 Focusing on Patterns and Functions

서경혜,유솔아,정진영 한국수학교육학회 2003 初等 數學敎育 Vol.7 No.1

The present study examined the 7th national elementary school mathematics curriculum from a perspective of mathematical creativity. The study investigated to what extent the activities in the Pattern and Function lessons in the national elementary school mathematics textbooks promoted the development of mathematical creativity. The results indicated that the current elementary school mathematics curriculum was limited in many ways to promote the development of mathematical creativity. Regarding the activities in Pattern lessons, for example, most activities presented closed tasks involving finding and extending patterns. The lesson provided little opportunities to explore the relationships among various patterns, apply patterns to different situations, or create ones own patterns. In regard to the Function lessons, the majority of activities were about computing the rate. This showed that the function was taught from an operational perspective, not a relational perspective. It was unlikely that students would develop the basic understanding of function through the activities involving the computing the rate. Further, the lessons had students use exclusively the numbers in representing the function. Students were provided little opportunities to use various representation methods involving pictures or graphs, explore the strengths and limitations of various representation methods, or to choose more effective representation methods in particular contexts. In conclusion, the lesson activities in the current elementary school mathematics textbooks were unlikely to promote the development of mathematical creativity.

문제: 조직병리검사의 처방이 복잡하고 전문화됨에 따라 오류처방이 빈번하게 발생되고 이를 해결하기위한 프로세스가 복잡하여 부서간의 갈등과 업무의 가중, 또한 병원 수입 감소가 초래되었다. 목적: 발생된 오류처방의 유형과 발생율, 오류처방을 해결하기 위한 프로세스를 파악하여 이에 대한 문제점을 개선하여 업무의 효율성과 관련부서간의 부가업무 감소와 갈등해소, 더불어 병원수익을 향상시키는 것에 목표를 두고 활동하였다. 의료기관: 서울시에 소재한 종합병원 질 향상 활동: 조직병리검사 처방의 오류처방 발생 원인과 유형, 발생율을 조사하여 원인을 파악하고 개선을 위한 프로세스를 구축하여 질 향상을 도모하였다. 개선효과: 수술실에서 의뢰한 외과 입원환자의 일반조직병리검사 오류율은 개선 전 7.8%에서 개선 후 3.5%, 동결절편조직검사 오류율은 개선 전 28.6%에서 개선 후 0%로 이전보다 모두 개선되었다. 또한 수술실 간호사의 업무 만족도는 일반조직병리검사의 처방시 95%, 동결절편조직검사 처방시 90%로 높은 만족도를 보였다. 단 병리과의 경우 업무가 증가됨에 따라 초과근무시간이 증가하였다.

In external image of person, face image is given a great deal of weight on the total personal appearance. Especially hairstyle have immediate connection with face image. The purpose of this paper was to analyze the face image by the types of hairstyle and the shapes of face. Three factors(facial shape, hair length, curl) were considered. Facial images were evaluated by the twenty adjective words on a Likert scale. Two subjects(a oblong face, a round face) were selected as female students of Wonkwang University. The results are as follows; 1. Five factors on the face image were extracted from twenty items ; femininity, urbanity, individuality, cuteness, intelligence. 2. In the face type, round face was explained by the softness, feminine, innocent image than oblong. 3. In the hair length, long hair was explained by the softness, natural, lovely image than short hair. 4. In the curl or straight, straight was explained by the vigorous, activity, youthful image than curl.

Seo-Yeong Park,Min Ju Kim,Siwon Yoo,Jin Woo Song,Jong Min Choi,Seo Hee Lee,In Hwan Kim,Ginnae Ahn 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

In this study, we prepared two enzymatic extracts by using trypsin and pepsin from Hermetia Illucens (THI and PHI), and evaluated their effects on photodamages in ultraviolet B (UVB)-irradiated human keratinocytes. The result showed PHI led to the higher extraction yield than THI, whereas the protein content of PHI was lower. Also both THI and PHI decreased the generation of intracellular reactive oxygen species (ROS) without the cytotoxicity at the used all concentrations in UVB-irradiated human keratinocytes. In particular, THI reduced the formation of apoptosis and the sub-G1 DNA content. In conclusion, we demonstrate that Hermetia Illucens enzymatic extracts suppress photo damages by inhibiting the oxidative stress of UVB-irradiated human keratinocytes.
