사교육의 발달과 교육환경의 변화로 인하여 학원홍보와 학생과의 커뮤니티 및 모바일 환경에서 학원관리의 다양한 업무 사항에 대하여 학원관리시스템의 필요성이 대두되고 있다. 하지만 학생들의 등하교에 따른 출석관리와 후원자에게 공지사항 전달 및 강사 관리 등, 기존의 학원 업무를 위해 개발된 솔루션들은 대형학원 위주로 특화되고 전문화되어 있어 중소규모의 학원에는 사용이 어렵고, 비용이 고가이기 때문에 대부분의 학원에는 적합하지 못하고 학원들의 다양한 요구사항을 반영할 수 없는 문제점이 존재한다. 따라서, 본 논문은 학원의 일반적인 업무에 대한 요구사항을 추출하고, 추출된 요구사항을 분석 및 정의하여 학사행정 및 매니저관리, 출결관리, 학생관리 등 학원업무 최적화된 기능을 기반으로 신속 정확한 정보처리와 신뢰도 향상 및 업무 처리 비용을 절감할 수 있는 B2M 기반의 학원관리시스템을 설계하였다. Due to the development of private education and changes in the educational environment, the need for an academy management system is emerging for various tasks of academy management in the community and mobile environment with students. However, solutions developed for existing academy tasks, such as attendance management for students, announcement, and instructor management to sponsors, are specialized and specialized in large academy, making it difficult to use in small and medium-sized academy. Also, there are problems that are not suitable for most academy and cannot reflect various requirements of institutes because of the high cost. In order to solve these problems, this paper designed a B2M-based academy management system that can quickly improve information processing, improve credibility, and reduce the cost of processing tasks based on optimized functions such as academic administration and manager management, attendance management, and student management.

초등수학영재의 분수 나눗셈의 이해에 관한 연구

김영아,김동화,노지화,Kim, Young A,Kim, Dong Hwa,Noh, Ji Hwa 영남수학회 2016 East Asian mathematical journal Vol.32 No.4

The purpose of this study was to analyze the understanding of the meaning of fraction division and fraction division algorithm of elementary mathematical gifted students through the process of problem posing and solving activities. For this goal, students were asked to pose more than two real-world problems with respect to the fraction division of ${\frac{3}{4}}{\div}{\frac{2}{3}}$, and to explain the validity of the operation ${\frac{3}{4}}{\div}{\frac{2}{3}}={\frac{3}{4}}{\times}{\frac{3}{2}}$ in the process of solving the posed problems. As the results, although the gifted students posed more word problems in the 'inverse of multiplication' and 'inverse of a cartesian product' situations compared to the general students and pre-service elementary teachers in the previous researches, most of them also preferred to understanding the meaning of fractional division in the 'measurement division' situation. Handling the fractional division by converting it into the division of natural numbers through reduction to a common denominator in the 'measurement division', they showed the poor understanding of the meaning of multiplication by the reciprocal of divisor in the fraction division algorithm. So we suggest following: First, instruction on fraction division based on various problem situations is necessary. Second, eliciting fractional division algorithm in partitive division situation is strongly recommended for helping students understand the meaning of the reciprocal of divisor. Third, it is necessary to incorporate real-world problem posing tasks into elementary mathematics classroom for fostering mathematical creativity as well as problem solving ability.

Young A Kim. 2014. English Hedge Expressions and Korean Endings: Grammar Explanation for English-Speaking Leaners of Korean. Journal of Korean Language Education 25-1: 1-27. This study investigates how common English hedge expressions such as ``I think`` and ``I guess`` appear in Korean, with the aim of providing explicit explanation for English-speaking leaners of Korean. Based on a contrastive analysis of spoken English and Korean corpus, this study argues three points: Firstly, ``I guess`` appears with a wider variety of modalities in Korean than ``I think``. Secondly, this study has found that Korean textbooks contain inappropriate use of registers regarding the English translations of ``-geot -gat-``: although these markers are used in spoken Korean, they were translated into written English. Therefore, this study suggests that ``-geot -gat-`` be translated into ``I think`` in spoken English, and into ``it seems`` in the case of written English and narratives. Lastly, the contrastive analysis has shown that when ``I think`` is used with deontic modalities such as ``I think I have to``, Korean use ``-a-ya-get-``: the use of hedge marker ``I think`` with ``I have to``, which shows obligation or speaker``s volition turns the deontic modalities into expressions of speaker``s opinion.(Monash University)

Objective : To investigate the efficacy of high infusion frequency of liquid nitrogen on pregnancy in human embryo after freezing and thawing. Materials and Methods: 150 infertile patients underwent 162 consecutive thawing-ET cycles. In the high infusion frequency group (Group A), 47 patients (50 cycles) underwent cryopreservation with high infusion frequency of liquid nitrogen. In the low infusion frequency group (Group B), 103 patients (112 cycles) underwent cryopreservation with low infusion frequency of liquid nitrogen. We analyzed the clinical characteristics, fertilization rates, development of embryo, good quality embryo ratio, implantation rates, and pregnancy rates between these two groups. Results: There was no difference between the groups with regard to clinical characteristics (mean age, infertility duration, infertility factors, hormone profile), mean number of oocyte retrieval, fertilization rates, and mean embryo number of transfers. The survival rates in group A was 64.9% (228 of 350 embryos), and among the 228 embryos 190 embryos (83.3%) which progressed to the two- to eight-cell stage. After thawing, the embryo numbers were 65 (34.2%), 29 (15.3%), 35 (18.4%), and 37 (19.5%) of grades 1, 2, 3, and above 4, respectively. The survival rates in group B was 63.8% (482 of 755 embryos), and among the 482 embryos 465 embryos (96.5%) which progressed to the two- to eight-cell stage. After thawing, the embryo numbers were 106 (22.8%), 94 (20.2%), 89 (19.1%), and 112 (24.1%) of grades 1, 2, 3, and above 4, respectively. There was no difference in embryo quality change after the freezing-thawing procedure between the groups. Implantation rates (31.1% vs. 34.3%) were not significant. However hCG positive rates in group A (40%) were higher than group B, but not statistically significant. Clinical pregnancy rate (26% vs. 25.9%), on going pregnancy rates (>20 weeks) were not significant (26% vs. 25%). Conclusion: We compared embryo quality change, survival rates, and pregnancy rates between high infusion frequency group and low infusion frequency group and the results were similar between the two groups. Therefore, high infusion frequency of liquid nitrogen for cryopreservation is a worthy method to preserve in human embryos.

$3^{3}$ 요인배치법에 의하여, 농도 저장시간 저장온도의 차이에 따를 도토리묵의 물리적 특성 변화를, Instron Universal Testing Machine을 사용하여 측정 비교하였다. 도토리묵의TPA curve는 첫 번째 압착에서 두개의 peak를 보이고, negative peak는 나타나지 않았다. 견고성과 절단성은 농도 저장시간 저장온도의 세 인자들의 변화에 대해 매우 유의적인 차이를 보이고, 두 peak의 높이 차이는 농도와 저장온도의 변화에 의해 특히 영향을 받으며 저장시간의 효과도 무시할 수 없었다. Bend는 농도의 변화에 대해서는 민감하게 대응하나 저장온도의 영향은 다소 약하게 작용하며 저장시간에 따른 변화는 무시할 수 있었다. 탄성은 농도의 변화에 대해서만 유의적인 차이를 보였다. The textural properties of acorn flour gels were investigated with the variations in the concentraction, storage time and storage temperature by the use of Instron Universal Testing Machine. The experimental design was $3^3$ factorial experiment. TPA curves of acorn flour gels showed two sharp peaks in the first bite and no negative peak. The hardness and brittleness of acorn flour gels were very significantly affected by concentration, storage time and storage temperature. For the height difference between first peak and second peals, the main effects for concentration and storage temperature were very significant and the main effect for storage time was not negligible. For bend, the effect of concentration was more significant than the effect of storage temperature, and storage time effect was negligible. Springiness was affected only by the concentration.

김영아,이혜수,Kim, Young-A,Rhee, Hei-Soo 한국식품과학회 1985 한국식품과학회지 Vol.17 No.6

도토리묵의 관통검사와 Back Extrusion test를 실시하여 각각의 특징적인 force-distance curve를 구하였다. 관통검사시에 관여하는 compression force와 shear force의 기여도를 알기 위하여 $K{\acute{c}}$와 $K{\acute{s}}$를 계산하였다. 도토리묵의 관통에는 compression force가 훨씬 더 크게 기여하고, 도토리묵의 농도가 클수록 탐침의 지름이 커질수록 그 기여도가 더 증가하였다. Back Extrusion test에 의해 얻어지는 maximum Extrusion force는 시료량의 증감에는 변화가 없었지만, 도토리묵의 농도가 증가함에 따라서는 그 값이 증가하였다. The typical force-distance curves by puncture test and Back Extrusion test of acorn flour gels were investigated. Kc' and Ks' were calculated to estimate the compression and shear components of a puncture force. In this study, compression effect played a major role. The more concentration of acorn flour gel and diameter of probe increased, the more compression force contributed to the puncture force. In the Back Extrusion test, the effect of increasing the sample size was to extend the length of the plateau without affecting the maximum force. However, as the concentration of acorn flour gel increased, maximum Extrusion force became larger.

김영아,정향인,Kim, Young A,Cho Chung, Hyang-In 한국디지털정책학회 2014 디지털융복합연구 Vol.12 No.12

본 연구에서는 여대생의 미용성형 중독성향에 영향을 미치는 요인을 조사하였다. 여대생 223명을 단순무작위 표집하여 성형수술 수용성, 외모에 대한 사회문화적 척도, 신체-자아에 대한 다차원 설문지, 자아존중감을 조사하였다. 자료수집은 2014년 5월에 이루어졌고 서술적 통계, chi-square test, ANOVA, logistic regression analysis로 분석하였다. 성형중독 성향과 관련된 각각의 변수를 안정군, 긍정적기대군, 중독위험군, 중독군과 비교분석하였다. 연구결과 안정군 21.1%, 긍정적기대군 35.0%, 중독위험군 32.7%, 중독군 11.2%가 확인되었고, 전체의 45.7%는 성형수술의 개인적인 경험이 있었다. 미용성형의 경험, 높은 성형수술 수용성, 높은 외모에 대한 사회문화적 태도, 높은 신체상(외모평가)은 미용성형 중독성향을 증가시켰다. 이러한 결과를 토대로 일반인들을 위한 성형중독 예방, 조기 발견 및 치료 프로그램을 개발하고 적용할 수 있을 것이다. 미용성형 중독을 예방하기 위해 안전 가이드라인의 도입이 필요하고, 조기성형수술, 사회문화적 영향, 신체상 변형의 예방이 중요하다고 제안한다. The purpose of this study was to examine influencing factors on plastic surgery addiction tendency. The participants, 223 undergraduate women, completed the ACSS, SATAQ, and MBSRQ. Data were collected from May, 2014 and analyzed using descriptive statistics, chi-square test, ANOVA, logistic regression analysis. Each of variables related to plastic surgery were analyzed between positive expectation group, addiction risk group, or addiction group compared to stable group. The prevalences of stable, positive expectation, addiction risk, and addiction group were 21.1%, 35.0%, 32.7%, and 11.2%, respectively. 45.7% had at least one personal plastic surgery. Personal experience of plastic surgery, high levels of ACSS (Consider), high levels of SATAQ (Internalization), and high levels of MBSRQ (Appearance Evaluation) were all associated with plastic surgery addiction tendency. The results of this study suggest that prevention of early plastic surgery, sociocultural influence and body image disturbances as well as safe guidance for plastic surgery are important in preventing the plastic surgery addiction.
