초등수학 예비교사들의 분수에 대한 표상의 분석

이대현,서관석 한국수학교육학회 2003 初等 數學敎育 Vol.7 No.1

Representation has been main topic in teaching and learning mathematics for a long time. Moreover, teachers' deficiency of representation about fraction results in teaching algorithms without conceptual understanding. So, this paper was conducted to investigate and analysize the elementary preservice mathematics teachers' representation about fraction. 38 elementary preservice mathematics teachers participated in this study. This study results showed that, the only model of a fraction that was familiar to the preservice teachers was the part of whole one. And research showed that, they solved the problems about fraction well using algorithms but seldom express the sentence which illustrates the meaning of the operation by a fraction. Specially, the division aspect of a fraction was not familiar nor readily accepted. It menas that preservice teachers are used to using algorithms without a conceptual understanding of the meaning of the operation by a fraction. This results give us some implications. Most of all, teaching programs in preservice mathematics teachers education have to devise to form a network among the concepts in relation to fraction. And we must emphasize how to teach and what to teach in preservice mathematics teachers education course. Finally, we have to invent the various materials which can be used to educate both preservice teachers and elementary school students. If we want to improve the mathematical ability of students, we will concentrate preservice teachers education.

안창범,주용석,정관식,서경란,신태선 여수대학교 1998 論文集 Vol.13 No.2

본 실험은 습사료를 대상으로 보관조건(온도별, 시간별)에 따른 지질의 산화진행 정도를 파악하여 사료의 효율적인 이용성을 구명하고자 산가(acid value, AV), 과산화물가(peroxide avlue, POV) 및 비타민 함량을 분석하였다. 생사료와 분말배합사료를 혼합하여 제조한 습사료는 혼합비가 8:2 사료에서 5:5 사료보다 높은 AV와POV를 나타내었고, 보관기간이 경과함에 따라 보관조건과는 상관없이 8:2 사료에서 빠른 산패를 보였다. 산화진행속도는 4℃ 보관조건하에서는 48시간째, -15℃ 보관조건하에서는 72시간째에서 빠르게 일어났다. 60,000 Lux이상의 직사광선 노출하에서의 AV,POV는 노출시간이 길어질수록 증가하였고, 8:2사료에서 빠르게 변화하였다. This experiment was conducted to investigate rancidity in moist pellet(MP) during various practical condition of handling and storage conditions. The experimental moist pellet diets were prepared by mixing frozen raw fish (FRF) and commercial compound meal (CCM) in ratio of 8:2 and 5:5, respectively. Immediately before and after manufacturing of MP, the MPs were stored at 4℃ and -15℃, and exposed under the sunlight(30±2℃, 60000Lux). The rancidity of each MP was determined from 1 to 96 hours after pellting. The acid value (AV) and peroxide value (POV) in the diets stored at 4 and -15℃ increased rapidly after 48 and 72 hours, respectively. For the sample exposed sunlight, AV and POV were slightly increased with the exposed time. The rancidity increased in the 8:2MP(FRF : CCM) than in the 5:5MP(ERF : CCM) at all storage condition and the amount of vitamin E in MPs decreased rapidly as AV and POV increased.

김용태,엄민식,이석영,신관희,서정원,윤석중,이상철,김원재 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.2

연구목적: 진성 복압성 요실금의 치료법으로서 복강경을 이용한 Burch 수술을 타수술법과 비교하여 그 유용성을 알아보고자 하였다. 대상 및 방법: 진성 복압성 요실금을 주소로 본원 비뇨기과에서 수술을 시행받은 44명의 환자를 수술법별로 분류하여 수술법에 따른 성공률, 수술 시간, 입원 기간 및 합병증의 빈도를 비교 분석 하였다. 결과: 전체 환자에서 수술 성공률은 86.4% 였으며 이들 중 복강경을 이용한 Burch 수술군에서는 성공률이 100% 이었다. 복강경을 이용한 Burch 수술군은 타수술군에 비하여 입원 기간이 짧았다. 복강경을 이용한 Burch 수술군은 합병증이 매우 경미하였으며 전체 환자의 31.8%에서 단기간의 배뇨곤란을 호소하였으나 장기간의 배뇨곤란은 없었으며 슬링 수술군에서는 3례(16.7%)에서 심한 절박성 요실금을 호소하였다. 결론: 복강경을 이용한 Burch 수술은 높은 치료 성공률과 낮은 합병증의 빈도를 나타내어 진성 복압성 요실금의 치료에서 매우 우수한 수술법으로 사료된다. Purpose: We performed this study to investigate the usefulness of laparoscopic Burch colposuspension as a treatment of genuine stress incontinence compare to other anti-incontinence operation. Materials and Methods : We analyzed success rate, operation time, admission day, and complication rate of various anti-incontinence operations in 44 genuine stress incontinence patients who have been received operation in our hospital. Results : Overall success rate was 86.4%, but laparoscopic Burch coposuspension showed 100% success rate. Laparoscopic Burch colposuspension required shorter admission day compared to other anti-incontinence oparations. Complication rate was lower in laparoscopic Burch colposuspension group. Short-term voiding problems were identified in 31.8% of total patients but 3 patients(16.7%) who have received sling operation complained severe urge incontinence. Conclusion : Laparoscopic Burch colposuspension is considered as an effective surgical method for genuine stress incontinence due to high success rate and low complication rate.

Purpose: The evaluation of a lecture by students is one of the good way to improve a lecture. In one medical school, we started one-year-integrated-lecture curriculum for sophomore. And we evaluated lectures using formal lecture evaluation sheet after completion of each integrated lectures. The results were fed back to lecturers. But lecturers were indifferent to the results. So we performed this study to evaluate the current lecture evaluation method. Methods: Answering patterns of evaluation sheets were reviewed. 50 students entitled to integrated lectures were given structured questions. 44 of them recovered. And randomly selected 10 students were interviewed. Results: Analysis of evaluation sheets showed that some students checked the items just for fun. More than half of the students answered that they did not check the questions seriously. Reasons why the evaluation of lectures were not going well were; students were not trained to evaluate something; evaluation sheet was not designed to evaluate individual lecturer; listed items were too many in number and inappropriate; some students were suspicious about the impact of evaluation of lectures. In addition to this, it was revealed that students thought the timing of evaluation of lecture was important, too. Conclusion: Indifference of lecturers to the results is one form of resistance to the evaluation of lectures by students. To make evaluation of lectures effective, numbers and contents of evaluation items must be selected carefully, students need to be trained, and adequate evaluation timing should be determined with frequent feed backs.

Review on Evaluation of Rare Earth Metals and Rare Valuable Metals Contained in Coal Ash of Coal-fired Power Plants in Korea

Park, Seok-Un,Kim, Jae-Kwan,Seo, Yeon-Seok,Hong, Jun-Seok,Lee, Hyoung-Beom,Lee, Hyun-Dong Korea Electric Power Corporation 2015 KEPCO Journal on electric power and energy Vol.1 No.1

Distribution of rare earth metals (REMs) and rare valuable metals (RVMs) contents in coal ashes (fly ash, bottom ash, and pond ash) and leachate from 11 coal-fired power plants in Korea were investigated. Coal ashes and leachates were found to contain important REMs and RVMs such as Yttrium (Y) and Neodymium (Nd), which was in the range of 23~75 mg/kg. However, it still requires developing effective recovery and separation methods in order to utilize REMs and RVMs in ash and leachate. Recovery of valuable elements (Y and Nd) from various and extensive ash sources (8.21 million tons/year in 2013) can provide the existing power plants with additional profit; therefore, it can significantly improve economics of the power plants.

서기석,임희관,김종성,임정식 圓光大學校 醫科學硏究所 1996 圓光醫科學 Vol.14 No.2

Background: Ever since Pereyra described needle suspension of the bladder neck as a form of surgical therapy for the treatment of urinary stress incontinence in women numerous modifications have been presented. Each of these modifications has helped to found healthy anatomical and surgical principles that ensure patient safety, decrease morbidity and improve effectiveness. A late modifications has been described by Raz. But the long-term success rate of Raz approach was not defined. Therefore we evaluated our result with a special interest in the long-term follow-up. Methods: The 34 women with genuine stress urinary incontinence underwent Raz bladder neck suspension from May 1994 to May 1997. All patients were assessed of their age, preoperative beeded chain cystourethrography, preoperative M-M test and Q-tip test, operative time, complication, and success rate. Results: Mean age of patients was 49.1(35-72) years. Severity of incontinence were grade Ⅰ in 2, grade Ⅱ in 29 and grade Ⅲ in 3 patients. The success rate were 85.3%(29/34) after 3 months, 80%(24/30) after 6 months, 75%(15/20) after 12months and 60%(6/10) after 24 months. The overall success rate was 73.5% at mean 17.3 months of follow-up. Complications included prolonged suprapubic pain(23.5%), weak urinary stream (11.8%), vaginitis(2.9%), prolonged retention(2.9%) and prolonged hematuria(2.9%). Conclusions: The Raz bladder neck suspension for correction of stress urinary incontinence has been successful, but the success rate decreased in this results according to follow up duration. Longer term results within this data will be reported in the future.

지각된 최고경영자 윤리의식과 조직몰입도의 관계

서균석,박동진,박찬관 안동대학교 경영연구소 1998 경영연구 Vol.2 No.1

본 연구는 최고경영자 윤리의식과 구성원의 조직에 대한 몰입도의 관계를 실증분석 하였다. 분석결과에 따르면, 구성원 조직몰입도를 높이기 위해서 최고경영자는 기업조직을 대표하는 입장에서 대외적 윤리의식이 매우 높다는 점을 구성원들이 지각할 수 있도록 행동해야 한다. 반면에 최고경영자가 조직을 관리하는 주체적 입장에서의 대내적 윤리의식의 유형에서는 직원의 실수나 과오를 묵인하면 조직몰입도를 저하시키는 것으로 나타났다. 그러나 구성원들에게 정직과 성실을 강조하고, 공용물품을 개인용으로 유용하는 것을 방지하는 노력 같은 것은 몰입정도에 별다를 영향력이 없는 것으로 분석되었다.
