This study determined the relationship between grit and self-regulated learning in South Korean teens in order to gain an understanding of grit, which is still at the beginning stage of the research, and to obtain implications for Korean learners' self-directed learning. This study also clarified the process by which learners are involved in selecting effective goals for self-directed learning and to provide cognitive efficacy for learners to encourage efforts to achieve their goals. This study was conducted over the period of 4 weeks, and was mainly targeted at the middle-school and high-school boys and girls in Daejeon, Sejong and Cheonan by using 376 collected survey questionnaires. Confirmatory factor analysis, reliability analysis, correlation analysis, structural equation, and Sobel-tests were performed using SPSS 23.0 and AMOS 23.0 for the data analysis. The hypothesis test results of this study are as follows. First, the grit of teens had a positive influence on their academic self-efficacy. Second, the grit of teens had a positive influence on their self-directed learning. Third, academic self-efficacy of teens was found to have a positive effect on their self-directed learning. Fourth, academic self-efficacy of the teens had a mediating effect in the relationship between the teens' grit and self-directed learning. 본 연구는 국내 청소년을 대상으로 그릿과 자기조절 학습 간의 영향력 관계를 규명함으로써 그릿에 대한 이해를 높이고, 학습자의 자율적 학습을 실천하기 위한 시사점을 얻고자 하였다. 또한 학업적 자기효능감의 매개효과를 검증함으로써 학습자가 스스로의 자기주도 학습을 위해 효과적인 목표 선정에 관여하고 목표 성취를 위한 노력 유발에 학습자 내적인 효능감을 제공하는 과정을 밝히고자 하였다. 본 연구는 충청도 소재 중·고등 학생을 대상으로 2019년 7월 1일부터 4주간 설문조사를 실시하여 376부의 자료를 사용하였다. 자료 분석은 SPSS와 AMOS를 활용하여 확인적 요인분석과 신뢰도 및 상관관계 분석, 구조방정식, Sobel-test를 실시하였다. 본 연구의 가설검증결과는 다음과 같다. 첫째, 청소년의 그릿은 학업적 자기효능감에 정의 영향을 미치는 것으로 나타났고, 둘째, 청소년의 그릿은 자기주도 학습에 정의 영향을 미치는 것으로 나타났다. 셋째, 청소년의 학업적 자기효능감은 자기주도 학습에 정의 영향을 미치는 것으로 나타났다. 넷째, 청소년의 그릿과 자기주도 학습 관계에서 학업적 자기효능감은 매개효과가 있는 것으로 나타났다.

Gamete intrafollopian transfer, a varient of IVF, is becoming increasingly popular as a treatment modality for infertility in women with at least one healthy follopian tube. Although GIFT has recently been poprlarized as a safe and effective treatment in selected infertile couples, little discussion of potential complications has been published. Whereas a tubal pregnancy rate of approximately 5% has been noted for IVF, early reports of GIFT have noted ectopic pregnancy to be relativiely rare. We experienced a case of combined pregnancy following GIFT with microsurgery and now present it with brief review of related literatures.

Seventy-two patients initiated intrauterine insemination between March 1989 and March 1990. Indication for the intrauterine insemination included abnormal semen, poor cervical mucus, presents of sperm antibody, unexplained, poor postcoital test and endometriosis. During this time period, 216 inseminations were performed and resulted in twenty four pregnancies in the 72 patients receiving artificial insemination by homologous donor for an overall pregnancy rate of 33.3%. Where pergonal treatment was followed by insemination, a significantly greater pregnancy per cycle was achieved. It is therefore suggested that a trial if induction of multiple follicular development be performed on coulpes with male-related or unexplained infertility before inclusion in protocols for invasive procedures, such as IVF or GIFT.

This study was aimed to investigate the effect of Ginseng on the glycogen contents in CCl_1 intoxicated rat liver. For this study, the experimental animals were divided into, 4 groups; norma| group, CCl_1 intoxicated control group. G-Ⅰ group treated with Ginseng after CCl_1 intoxication and G-Ⅱ group treated with Ginseng both before and after CCl_1 intoxication. And animals were sacrificed at the intervals of 12 hours, 1, 2, 4 and 6 days following the CCl_1 feeding. Glycogen granules in hepatic lobule were stained by method of Periodic acid-Schiff reaction. The results obtained are summarized as follow; 1 The glycogen in hepatic lobule in normal group showed strong PAS reaction, but that in CCl_1 intoxicated control group showed PAS negative reaction at 12 hours and 1 day. mild PAS reaction at 2 and 4 days and strong PAS reaction at 6 days after the CCl_1 intoxication 2, The contents of glycogen in central region of hepatic lobule in G-Ⅰ and G-Ⅱ group showed slight increase as compared with CCl_1 intoxicated control group at 4 days after the CCl_1 intoxication. 3. The contents of glycogen in peripheral region of hepatic lobule in G-Ⅰ group showed significant increse as compared with CCl_1 intoxicated control group at 4 days after the CCl_1 intoxication, and that in G-Ⅱ group showed significant increase at 12 hours 1, 2 and 4 days 4. The increase of glycogen contents in hepatic lobule was more prominent in peripheral region than in central region, especially this effect was also more prominent in G-Ⅱ group than in G-Ⅰ group. As mentioned above it has been shown that the glycogen contents of hepatic lobule was reduced by carbon tetrachloride and was rapidly increased in a Ginseng-treated liver.

Image segmentation is the process where an image is segmented into regions that are set of homogeneous pixels. The result has a ciritical effect on accuracy of image understanding. In this paper, an Markov random field (MRF) image segmentation is proposed using genetic algorithm(GA). We model an image using MRF which is resistant to noise and blurring. While MRF based methods are robust to degradation, these require accurate parameter estimation. So GA is used as a segmentation algorithm which is effective at dealing with combinatorial problems. The efficiency of the proposed method is shown by experimental results with real images and application to automatic vehicle extraction system. 영상분할은 입력된 영상을 처리하여 유사한 화소들의 집합인 영역들로 화소들을 구분하는 작업이다. 영상분할의 결과는 영상인식의 정확성에 큰 영향을 미친다. 본 논문에서는 유전자 알고리즘을 이용하여 마르코프 랜덤 필드(Markov random field)에 기반한 영상분할 방법을 제안한다. 제안한 방법에서는 잡음과 흔들림(blurring)에 강한 MRF를 이용하여 영상을 모델링 한다. HRF기반 영상분할 방법은 왜곡에 강한 반면, 정확한 파라미터의 추정이 요구된다. 그래서 , 추정방법으로 많은 파라미터를 포함하는 문제를 다루는데 효율적인 유전자 알고리즘을 사용한다. 실 영상을 가지고 수행된 실험 결과와 자동 차량 추출 시스템에의 응용결과는 제안된 방법의 효율성을 보여준다.

조경시공 관리에서 사다리 안전사고 예방을 위한 전도 안정성 평가 - 국내에서 사용되고 있는 삼각지지형 이동식 사다리를 대상으로 -

본 연구는 조경시공 및 관리분야에서 수목관리, 전지 등과 같은 고소부위 작업을 위해 주로 사용하는 삼각지지형 이동식 사다리의 전도 안정성을 평가한 것이다. 산업현장에서 사용 빈도가 높은 이동식 사다리에 포함되는 삼각지지형 이동식 사다리는 작업 특성에 따라 바닥지지 형태가 일반적인 A형의 사면지지가 아닌 삼각지지 방식이고, 작업 높이도 이동식 사다리와 비교하여 2배 이상 높기 때문에 떨어짐과 함께 작업자의 안전을 위협하는 전도 발생 가능성이 매우 높다고 할 수 있다. 따라서, 국내에서 사용되고 있는 삼각지지형 이동식 사다리를 대상으로 관련 기준인 ANSI-ASC A14.7과 EN 131-Part 7에서 규정하고 있는 전도 안정성 평가를 기반으로 하여 작업 높이에 따른 전도모멘트와 저항모멘트를 계산할 수 있는 수식을 각각 유도하여 계산한 후, 이 값을 상호 비교하여 전도에 대한 안전율 및 전도 방향에 따른 안정성을 평가하였다. 각 기준에 따른 전도 안정성 평가 결과, EN 131-Part 7의 규정을 적용하면 후면방향 8단과 측면방향으로 6단 이상의 삼각지지형 이동식 사다리는 전도에 대해서 불안정한 것으로 평가되었으나, ANSI-ASC A14.7의 규정에 의하면 방향에 상관없이 모든 단수에서 전도에 대한 안정성을 확보하고 있는 것으로 평가되었다. This study evaluated the overturning stability of portable tripod ladders used for high-altitude work such as tree management and pruning work in landscaping construction and management. Portable tripod ladders, which are included in general mobile or portable ladders frequently used in industrial sites, are supported in a triangular support structure, not a 4-point support like common A-type Ladders. In addition, since the working height is more than twice that of a mobile or portable ladder, the possibility of an overturning accident that threatens the safety of workers with a fall accident is high. Therefore, based on the overturning stability test specified in ANSI-ASC A14.7 and EN 131-Part 7, which are related standards for about 130 types of portable tripod ladders sold and used in Korea. An equation to calculate each moment according to working height was derived. Then, each calculated moment was compared to evaluate the safety factor for overturning and stability. As a result of the overturning stability evaluation according to each standard, when the provisions of EN 131-Part 7 were applied, portable tripod ladders with 8 steps in the rear direction and 6 steps or more in the side direction were evaluated as unstable against overturning, but according to ANSI-ASC A14.7 regulations. It was evaluated that the stability against overturning was secured in all directions and number of steps.
