박은아,문명진,Park, Eun-Ah,Moon, Myung-Jin 한국현미경학회 2009 Applied microscopy Vol.39 No.2

체판이 있는 자갈거미과 (Titanoecidae)의 거미를 실험재료로 체판류가 지닌 방적장치와 토사관의 미세구조적 특성을 고배율의 주사전자현미경(FESEM)으로 관찰하였다. 살깃자갈거미(Nurscia albofasciata)의 실크 방적장치는 복부의 방적돌기 위쪽에 있는 체판과 3쌍의 방적돌기로 이루어져 있었다. 체판은 정중면을 중심으로 분리된 두 개의 타원형 구조로, 표면에는 유연한 구조를 지닌 큐티클성 토사관들이 조밀하게 분포되어 있었고, 체판에서 생성된 수백가닥의 미세한 북슬털은 피식자의 보행을 방해하는 포획사의 기능을 수행할 것으로 추정되었다. 한편 방적돌기에서는 병상선, 이상선, 포도상선 등 3종류의 실크 분비선이 모든 성별에서 관찰되었는데, 병상선은 전 및 후방적돌기를 통해 연결되어 있었고, 이상선은 전방적돌기를 통해, 그리고 포도상선은 중 및 후방적돌기의 표면을 통해 토사관이 형성되어 있었으며, 성별에 따른 토사관의 다형현상은 확인되지 않았다. 특징적으로 이 종류의 거미에서는 두 종류의 포도상선이 관찰되었는데, 이 중에서 B형 포도상선은 후방적돌기에서만 관찰되었고, 체판의 토사관과 유사한 미세구조적 특성을 지니고 있음이 확인되었다. Here we demonstrate the fine structural characteristics of the spigots on the cribellum and its peculiar sieve-like structure at the aspects of the functional significance. The surface of the cribellum is covered by hundred of tiny spigots which producing numerous cribellate silk fibrils. It has been known that the cribellar silk is considered as a quite different sort of catching silk with dry-adhesive properties. By our fine structural observation using the field emission scanning electron microscopy (FESEM), the titanoecid spiders have a specialized sieve-like plate just in front of the anterior spinnerets. The other types of the silk spigots were identified as follows: ampullate, pyriform and aciniform glands. Two pairs of major ampullate glands send secretory ductules to the anterior spinnerets, and another 1~2 pairs of minor ampullate glands supply the median spinnerets. In addition, the pyriform glands send ductules to the anterior spinnerets, and the aciniform glands feed silk into the median and the posterior spinnerets, respectively. Characteristically, 2 distinct types (A & B types) of the aciniform spigots were identified in this spider, and the spigots of the aciniform B type are always detected at the posterior spinneret, however sexual dimorphism for spigot is unlikely to be exhibited in this species of spider.

1. Objective This research looks into the facial characteristics of Sasang constitution. 2. Methods It assigns and measures the length of nine areas of the face using a picture, and calculates the proportions and gives statistical data of these items. It also references the proportion of the items using the contents of "Sanghakjinjeon" ("相學眞傳") Ten face-types as a basis, divides the face into seven types, looks into the similarities between constitutions, and also compares it to clinically and frequently used constitutional facial characteristics. 3. Results and Conclusion After comparing the analytical items between Taeumins, Soyangins, and Soeumins, Soeumins had an oval face due to the fact that the length and width that their lower faces took up was small compared to the entire face. After dividing the facial characteristics of the test subjects using 十字相, there were significantly more Taeumins in Dong(同)_face-type, and Soeumins in Won(圓)_face-type. There weren't any significant group that Soyangins showed up in. After comparing these facial characteristics with that of previous facial characteristics found in books and used clinically, we were able to find corresponding items.

The purpose of this study was to investigate the differences in non-cognitive factors, specifically achievement goal orientation (AGO) and self-regulated learning (SRL), influencing the academic achievement (AC) of medical and nursing students. 186 students, including 110 medical students and 76 nursing students, completed a survey, which addressed the factors of AGO and SRL. There were significant differences in the factors that affected the academic achievement of medical and nursing students. Multiple regression revealed that the AC of medical students was significantly more affected by mastery-approach AGO (p<0.05), seeking information (p<0.001), and rehearsing/memorizing SRL (p<0.01), while the AC of nursing students was affected by performance-approach AGO, self-efficacy (p<0.001), and time-management SRL. Analysis of variance revealed that significant differences in the sub-factors of AGO and SRL between the medical and nursing students. Thus, it was found that the academic achievement of medical and nursing students was influenced by non-cognitive factors, but there were significant differences in the sub-factors by group. It is suggested that comparative studies with other student groups and a longitudinal study of medical and nursing students need to be conducted, and a personalized counseling and learning intervention focusing on non-cognitive factors should be provided to medical and nursing students.

박은아(Euna Park),송해덕(Hae-Deok Song) 중앙대학교 한국교육문제연구소 2014 한국교육문제연구 Vol.32 No.4

본 연구의 목적은 대학생의 핵심 역량 중 하나인 의사소통 역량 향상에 영향을 미치는 학습자 요인을 탐색하는 것이다. 의사소통 역량이 실제 교수·학습 상황에서 길러지는 역량임에도 불구하고 그동안 의사소통 역량과 관련된 연구들은 주로 교수법 개발이나, 일반적인 학습자 특성 등을 중심으로 이루어져 교수학습 맥락을 고려하는 데 미흡한 부분이 있었다. 따라서 본 연구에서는 교수·학습 맥락에서 의사소통 역량과 관련한 학습자 요인으로 의사소통 관련 수강 과목 수, 의사소통 중심 수업활동, ICT 활용 수업에 대한 유용성 인식을 설정하고, 각 요인이 의사소통 역량 향상에 미치는 영향을 다중회귀분석을 통해 검증하였다. 그 결과 의사소통 역량 향상에 가장 큰 영향을 주는 요인은 ICT 활용 수업에 대한 유용성 인식으로 나타났다. 끝으로 연구결과에 근거하여 대학생 의사소통 역량향상에 대한 시사점들이 제시되었다. The purpose of this study is to explore factors influencing the communication competence that draws attention as the key competency of the university learner. Many studies examined the factors affecting the improvement of learners’ communicative competence but are limited in the aspect of ignoring the learning environment and learner characteristics; that is, ICT utilization and the consideration for the attitude and awareness of the learner. The influence of three factors were examined: the numbers of communication courses that were taken, interaction between instructors and students, and perceived usefulness of ICT utilization class as independent variables. Factors that most influenced the improvement of communication competency were analyzed through multiple regression analysis of 4,030 university students. Findings shows that the more students thought that ICT utilization class was useful, the more they felt that their communication competences were improved. Through these results, this study found that the utilization of ICT in class helped learners improve communication competency, and suggested implications for communication teaching and studies.

Purpose: The purpose of this study is to review acute confusion of aged. Method: Review article. Rusult: Acute confusion is a common problem seen by health professionals who work in a variety of care settings and the incidence in older hospitalized patients is about 24% to 80%. Acute confusion have definitions that is abrupt onset of a cluster of global, transient changes and disturbances in attention, cognition, psychomotor activity level of consciousness, and sleep-wake cycle. The causes of acute confusion are multifactorial; risk factors include high age, cognitive impairment and severity of illness. The consequences of acute confusion include high morbidity and mortality, lengthened hospital stay. Acute confusion develops in a short period and symptoms fluctuate, therefore nurses are in a key position to recognize symptoms. Conclusion: Acute confusion is often overlooked or misdiagnosed due to lack of knowledge and awareness in nurses and health professionals. To improve early recognition of acute confusion, emphasis should be given to terminology, vision and knowledge regarding health in aging and acute confusion as a potential medical emergency, and to instruments for systemic screening of symptoms.

"ICT 활용능력"과 "사회과 학습 자기효능감"이 컴퓨터 기반 사회과 평가 결과에 미치는 영향

박은아 ( Eun Ah Park ),성경희 ( Kyung Hee Sung ) 한국사회과교육학회 2014 시민교육연구 Vol.46 No.1

최근 "컴퓨터 기반 평가(Computer Based Assessment)"가 전통적인 지필평가의 한계를 극복하는 혁신적인 평가 방법으로 주목받고 있다. 컴퓨터 기반 평가 시스템을 도입하고자 할때, 우려되는 문제는 학업성취와 상관없이 컴퓨터 활용능력이 평가 결과에 영향을 미칠 수 있다는 점이다. 이에 본 연구에서는 배경특성(성별, 지역)을 통제변인으로 하여, ICT 활용능력과 사회과 학습 자기효능감이 컴퓨터 기반 사회과 평가 결과에 미치는 영향력을 검증하였다. 그 결과를 요약하면 다음과 같다. 첫째, ICT 활용능력은 CBA 결과에 유의미한 영향력을 지니지 못한 반면, 사회과 학습 자기효능감은 평가 결과를 예측하는 중요 요인임이 밝혀졌다. 둘째, CBA 결과에 대한 성차와 지역 차이의 통계적 유의성을 확인할 수 있었는데, 여학생과 대도시 지역의 학생들의 성적이 더 높았다. 셋째, 평가 관련 내용에 대한 학습 여부, 즉 사전지식 소유 여부는 CBA 결과에 유의미한 영향력을 미치지 못하였다. 요컨대, 컴퓨터 기반 평가 시스템을 교육 현장에 도입하고자 할 때 우려되었던 ICT 활용 능력의 영향력 문제는 나타나지 않았고, 사회과 학습 자기효능감이 높은 학생들의 점수가 더 높게 나타난다는 점에서 CBA가 학업성취를 판단하는데 유용한 평가도구라고 할 수 있다. 다만 성별과 지역에 따라 학생들의 CBA 결과가 달리 나타난다는 점은 CBA 설계 및 실행에 있어 유념해야할 부분으로, 컴퓨터라는 매체 특성이 집단별로 상이한 영향력을 지니는지에 대한 후속 연구가 필요하다고 하겠다. Recently, Computer Based Assessment (CBA) has been receiving attention as a innovative assessment to overcome the limits of conventional test. One of the major concerns regarding the introduction of CBA is that computer test form might affect test scores depending on students` computer skills regardless of academic achievement. Thus, the current research aims to explore the effects of ICT literacy and self-efficacy for learning on students` CBA results with control variables of students` characteristics (gender, region). The results can be summarized as follows. First, while ICT literacy has no significant effect on CBT scores, self-efficacy of social studies learning has statistically significant effect on it. Second, statistical significance of regional and gender difference on CBA scores was verified, that is, scores of students who were female and resided in large cities were higher than those not. Third, previous knowledge related contents has no meaningful influence on CBA scores. In short, the problem of the disparity of CBA results depending on ICT literacy did not appear largely, and the scores of students who has high self-efficacy for social studies learning appear high. Therefore, CBA could be useful assessment means. Nevertheless, when designing and implementing CBA system, it should be paid attention to the facts that students` CBA scores depends on gender and region. It is necessary to conduct follow-up studies about that computer media traits could have differential effects on each group.

사회.문화 내용에 대한 중학교 학생의 성취수준

박은아(Park, Eunah) 한국열린교육학회 2010 열린교육연구 Vol.18 No.4

The purpose of this article is to analyze the achievement level of socio-cultural content of middle school students by using the 2004-2008 National Assesment of Social Studies Educational Achievement. The results showed that advanced level students within middle school have the ability to understand socio-cultural basic concepts and proficient level students can identify the social problem or social change content. The ability to grasp the meaning of materials is dependant on the academic achievement level. The advanced level students can infer the hidden meaning from several text materials and can correlate all the information needed for solving given problems. The proficient level students can explain the meaning from the text material and read the graphs. We can seek to improve students' achievement levels in socio-cultural education by changing the method of learning. 본 연구는 2004~2008년 학업성취도 평가의 사회.문화 문항을 분석하여 사회.문화 내용 이해에 대한 성취수준의 특성과 그에 적합한 학습 방안을 마련하는 것이다. 성취수준의 특성은 개념 이해와 자료 분석 능력 정도에서 두드러지게 나타났다. 관료제, 지위 등 기본 개념 이해도는 우수학력, 사회문제나 사회변화 관련 내용 이해도는 보통학력, 공식집단과 비공식집단의 특징 이해는 기초학력 수준이었다. 자료 분석에서는 우수학력은 하나 혹은 여러 개의 자료의 숨겨진 의미를 유추하여 문제를 해결하기 위해 정보를 종합하는 능력을 가지고 있었으며, 보통학력은 자료에 제시된 의미를 배경지식과 관련하여 설명하고 그래프를 읽어 낼 수 있었다. 따라서 보통학력 학생들에게는 기본 개념 이해도, 기초학력 학생들에게는 친숙한 생활 사례를 통해 사회문제나 사회변화의 기본 내용 이해에 초점을 맞춘 학습 방법이 요구된다.
