본 연구에서는 초등교사가 가지고 있는 열정에 대한 인식구조를 파악하기 위해 현직 초등교사 131명을 대상으로 설문조사를 실시하였다, 연구에서는 열정, 열정의 장단점, 교사열정에 대한 인식구조를 알아보기 위해 의미연결망 분석을 활용하여 근접 중심성, 연결중심성, 매개중심성, 아이겐벡터 중심성을 위주로 살펴보았다. 연구결과 첫째, 열정에서는 ‘힘’,‘강렬’과 같은 높은 강도나 에너지를 나타내는 단어들이 중요한 역할을 하였으며 커뮤니티 분석 결과 열정의 행동, 정서, 동기 특성에 대한 주제가 분류되었다. 둘째, 열정의 장점에서는 ‘삶’,‘원동력’,‘에너지’등이, 열정의 단점에서는 ‘타인’,‘피로’,‘살피지 못함’등이 중요한 역할을 하는 것으로 보아 기존 이론에 나타난 열정의 특성을 설명하고 있었다. 셋째, 교사열정에서는 ‘학생’,‘수업’과 같은 교수활동의 실천을 나타내는 단어들이 중요한 역할을 하였으며 커뮤니티 분석 결과 교육활동 전반, 학생과 수업, 전문성 개발에 대한 주제가 분류되었다. The purpose of this study was to explore the meaning of passion perceived by elementary school teachers. In order to understand the structure of perception of passion, we surveyed 131 in-service elementary school teachers. Responses to passion, the positive and negative role of passion, and teacher passion were analyzed using a semantic network analysis. We focused on closeness centrality, degree centrality, betweenness centrality and eigenvector centrality. Results showed that first, in passion, words indicating high strength and energy such as‘power’and‘intensity’played an important role in the structure of perception. Themes on behavioral, emotional, and motivational characteristics of passion were classified as sub-factors of passion as a result of community analysis. Secondly,‘life’,‘motivation’, and‘energy’appeared in key-word analysis in the positive role of passion while‘others’,‘fatigue’, and‘not caring for’appeared in the negative role of passion, reflecting the theory on the dualistic model of harmonious and obsessive passion. Third, in teacher passion, words indicating teaching activities and their practices such as‘student’and‘instruction’played an important role in the structure of perception. Themes related to educational activities in general, students and instruction, and professional development were classified as sub-factors of teacher passion.

This experiment was carried out to determine non-destructively water content in a intact fried noodle in oil by portable near-infrared system. Water content was ranged from 0 to 14.3w/w% and the near infrared (NIR) measurements were made on 70 intact samples over the spectral range 1100-1750nm. We found the variation of absorbance band due to OH vibration of water in the noodles depending on the concentration change around 1450nm in the second derivatives spectra. Partial least squares(PLS) regression models were set up using a calibration set(42 E.A.) and a validation set(28 E.A.) between the NIR response and value from loss on dry. Various pretreatments of the spectra were examined: the smallest stnadard error of prediction(0.35%) was obtained using autoscaling spectra over 1100-1700nm. 10 factors were required for the PLS model to give a good relationship between the spectral information and the noodle water content. In order to validate the developed calibration model, routine analyses were performed using other intact noodles. Water contents from the NIR calibration model were compared with the values from loss on dry and the results showed good correlation with those of loss on dry. This study showed that the rapid and non-destructive determination of water content in a intact fried noodle in oil was successfully performed by portable NIR system.

Agrobacterium tumefaciens를 이용한 bialaphos 저항성 형질전환 벼의 개발

이효연,이춘환,김호일,한원동,최지은,김진호,임용표 충남대학교 생물공학연구소 1999 생물공학연구지 Vol.7 No.-

비선택성 제초제인 bialaphos는 고등식물에 있어서 glutamine 합성을 억제하여 식물체를 고사시킨다. Acetyltransferase에 의해 encoding된 bialaphos 저항성 유전자는 세균 Streptomyces hygroscopicus SF1239로부터 cloning된 것을 사용하였다. Bialaphose 저항성 유전자를 Agrobacterium 감염법을 이용하여 국내에서 재배되는 벼(동진)에 도입한 결과 약 30%정도의 형질전환 식물체를 얻을 수 있었다. T_1세대의 17개체는 hygromycin과 bialaphos에 대한 저항성 유전형질이 3 : 1로 분리되었다. 또한 Southern 분석을 실시한 결과 wild type의 식물체에서는 Bar 유전자의 검출을 볼 수 없었으나 형질전환 식물체의 경우 Bar 유전자의 검출이 가능하였다. T_3 세대의 형질전환 식물체와 wild type의 식물체를 포장상태에서 비선택성 제초제인 바스타를 살포하고 3주 후에 관찰한 결과 형질전환 식물체는 외형적으로 아무런 피해를 받지 않고 정상적으로 생장하였으나, wild type의 식물체와 잡초는 모두 고사하였다. 이상의 결과를 종합해보면 hygromycin과 bialaphos 저항성 유전자는 Agrobacterium 감염법을 이용하여 단자엽 식물인 벼에 도입할 수 있다는 것을 보여준 것이며, 또한 bialaphos 저항성 유전자가 식물에 도입됨으로써 비선택성 제초제에 대한 저항성 식물을 개발 할 수 있다는 것을 보여 주었다. The bialaphos is a potent inhibitor of glutamine synthease in higher plants and is used as a non-selective herbicide. We have used the bialaphos resistant gene (Bar) encoding for an acetyltransferase isloated from Streptomyces hygroscopicus SF1293. Callus derived from mature seeds of rice (Oryza sativa L. cv. Dong Jin) were co-cultivated with Agrobacterium tumefacieus EHA101 carring a plasmid pGPTV-HB containing genes for hygromycin resistance (HygR) and Bar. Transgenic plants showing in vitro resistance to 50 mg/L hygromycin and 10 mg/L bialaphos were obtained by using a two-step selection/regeneration procedure. Transformation efficiency of rice was about 30% which was as high as reported in other dicotyledons. Progenies (T_1 generation) derived from primary transformant of 17 lines were segreagated with a 3 resistant:1 sensitive ratio in medium containing hygromycin and bialaphos. Stable integration of Bar gene into chromosomal DNA was proven by Southern blot analysis of genomic DNA isolated from T_2 progenies. Transgenic plants (T_3) grown in the field were resistant to bialaphos (Basta) at a dosage lethal to wild type plants.

As sports infiltrates each field of modern society and becomes familiar, sports wear was changed functionally and was introduced and enveloped into everyday dress. Modern sports wear has been the settled in everyday life deeply and become the clothes of life which are worn regardless of place, time and age. The aim of this paper was to clarify what kind of fashion of sports style would be given to the modern people. In this study, sports wear which has become everyday dress was classified from a gender point of view. It was divided into masculine image, feminine image, and neutral image. Sports wear of masculine image generated a silhouette which emphasized the shoulder with the aspiration for youth and health. Wide shoulder was considered as the symbol of masculine beauty and the expression of healthy beauty. It was reflected well in body conscious look. And owing to the development of up-to-date materials, innovation of design, and the study of human body technology, the functional character was settled in the sports wear which showed masculine image. Sports wear of feminine image was represented fashion of body exposure, body feet with body conscious look, and romantic mode. This image was expressed fashion as comforts, pleasant, active design, materials, color, and romantic feminine beauty. Sports wear of neutral image was expressed into unisex clothes. This cloths have no difference in gender, age, and class. It was used as casual sports wear. In the 1960s, young generation participated in such street sports as street basketball and skate. They usually wore the sports wears of neutral image such as cycling, skating, and ski. In the materials of sports, the development of up-to-date material like lycra made the sayings lifelike, "up-to-date material is the second skin" It show that glamorous feminine image and strong masculine image coexisted. The contemporary concept of sportswear is no longer limited to those clothes for sports found in such places like tennis court or swimming pool. Now, the sports wear become more like casual activity wear all classes of people can enjoy in their life regardless of where they are, when they wear, and even how old they are.

We have investigated the effects of hypha-water extracts (HWE), fruit body-water extracts (FWE) and cordycepin from Cordyceps militaris on serotonin release out of human platelets and human platelet aggregation. HWE and FWE inhibited the release of [^(3)H]-serotonin from human platelet stimulated by thrombin (2 U/ml) or collagen (20 ㎍/ml) in a dose-dependent manner. Furthermore, cordycepin, a major component of Cordyceps militaris, inhibited the human platelet aggregation induced by collagen (10 ㎍/ml) in a dose-dependent manner. These results suggest that cordycepin containing in HWE and FWE may inhibit the serotonin release by suppressing the collagen-induced human platelet aggregation. Accordingly, our data demonstrate that HWE and FWE containing much cordycepin might have antithrombotic and antimigrainous functions.

Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.
