  • 전통적인 방법에 의한 PER는 단순히 그 지표의 일반적인 높고 낮음에 따라 소위 '저평가 종목'이라는 이름으로 투자자들에게 추천되고 있다. 그러나 이런 방법은 개별기업의 구체적 내용을 정확하고 종합적으로 고려하지 못하고 있다. 본 연구는 전통적인 방법으로 사용되는 PER지표의 문제점을 개선코자 배당평가 모형으로부터 도출한 PER지표의 구성요소들을 독립변수로 활용 회귀분석을 했다. 그리고 이를 근거로 이론 지표를 만든 후, 그 이론 지표를 투자의사결정에 적용하였을 때의 유효성을 검증했다. PER지표를 구성하는 독립변수는 Kisor & Whitbeck(1963), Malkiel & Cragg(1970), A. Damodaran(1996)에 의해 연구된 것을 원용, PER지표의 구성요소들로 기업의 배당성향, 이익 성장을, 그리고 위험변수로서의 베타계수를 선정했다. 투자성과는 포트폴리오 투자가 일반적인 현실을 감안해 가치가중수익률을 사용한 포트폴리오의 투자성과를 측정했고, 표본은 국내 거래소 시장에 1991년부터 2001년까지 계속 상장된 금융업종을 제외한 전종목을 대상으로 했다. 실증분석에 사용된 기간은 1997년부터 2001년까지 5년 동안의 자료이며, 투자성과를 검증하기 위한 검증모형으로 위험 프리미엄 모형을 사용했다. 먼저 동 분석기간 중 전통적인 방법에 의한 PER효과는 나타나지 않았고, 아울러 기업규모 효과도 찾을 수 없었다. 그러나 회귀분석을 통해 구해진 이론 지표를 활용할 경우, 이론 지표에 비해 시장 지표가 과소 평가된 그룹이 과대 평가된 그룹과 비교할 때 투자성과가 더 우수한 것으로 나타났다. 또한 이론 지표를 통해 PER수준이 낮아짐에 따라 투자성과가 더 높아지는 PER효과도 발견됐다. 이와 같이 이론 지표에 의해 나타나는 PER효과는 기업규모 효과와는 독립적인 것으로 보인다. 외환위기 이후 우리시장에 나타난 차별화 장세 속에 아직도 PER효과나 기업규모 효과와 같은 시장이례 현상이 존재하는지는 관심의 대상이 됐다고 본다. 본 연구에 의하면 기업규모 효과와는 별개의 PER효과가 여전히 존재하며, 다만 이 PER 효과는 전통적 의미의 일반적으로 낮은 PER종목이 초과수익률을 내는 것이 아니라, 기업규모가 크더라도 그 기업의 개별특성을 고려했을 때 이와 비교해 상대적으로 PER가 낮은 종목에 투자하면 초과수익을 낼 수 있음을 의미한다.

  • In the era of the Fourth Industrial Revolution, talents should not be subordinated to a particular discipline, but must be able to converge a variety of disciplines. It is important to have a fused thinking because elementary school students are likely to make various changes. Therefore, when selecting elementary gifted students, they are selecting students for fusion gifted students. This study examines the effects of creative problem solving ability, document evaluation, and interview factors on student selection when selecting students for gifted students. The results show that creative problem solving ability has the most influence on selection. In the case of the fifth graders, the creative problem solving ability and the document evaluation influence the selection. In fourth graders, the creative problem solving ability and interview affect the selection. In the case of female students, it was found that creative problem solving ability and document evaluation influenced selection. In addition, there was a gender difference in the evaluation of documents in the gender difference analysis. There is no significant difference between the three groups in the grade-by-grade difference analysis.

  • This research, which is quite different from previous studies, has tried to understand the relationships among aesthetic dimensions, on the basis of product aesthetic and how these consumer preferences change according to changes of these dimensions. For this research, the factors of simplicity/complexity and balance among many aesthetic elements were chosen through experiment, and products which are on the market were divided into 4 categories with the FCB Grid. Two products of each respective category were selected and a typical model was chosen for each other. These models were changed only with the factors of simplicity/complexity and balance, in order to make a show-card. The relationships between simplicity/complexity, balance, and consumer preferences has been proven with the show-card. The measured value change of consumer preferences will be provided for design development as basic data. The relationship among the various aesthetic dimensions will improve through consistent research.

  • When simulating large crowds, it is inevitable that the models and motions of many characters will be cloned. McDonnell et al. analyzed user's perception to find cloned characters. They established that clones of appearance are far easier to detect than motion clones. In this paper, we expand McDonnell's research[1], with the focus on multiple clones and the appearance variety in real-time game environment. Introducing the perceptual organization, we show the appearance variety of crowd clones by using game items and texture modulation. Other factors that influence the ability to detect clones were examined, such as the moving direction and distance between character clones. Our results provide novel insights and useful thresholds that will assist in creating more realistic crowds of game environments.

  • As increasing interests in charitable giving, there is also a growing need to examine the factors which influences on consumer's giving behavior. Whereas past research focused mainly on one-time donation, this study examined how gender affects giving behaviors related to social connection with a donee. In Study 1, we found that compared to men, women showed more favorable attitudes toward the relationship based giving. Results from Study 2 revealed that, compared to male-primed women, female-primed women reported more positive giving intention. They are also more interested in interaction with donee. The current research demonstrates that gender differences leads to different responses towards the relationship based giving. Implications of this research for charity solicitation methods are discussed.

  • In this paper, we propose an effective method for the distinction between machine-printed and handwritten Korean address images. It is important to know whether an input image is handwritten or machine-printed, because methods for handwritten image are quite different from those of machine-printed image in such applications as address reading, form processing, FAX routing, and so on. Our method consists of three blocks: valid connected components grouping, feature extraction, and classification. Features related to width and position of groups of valid connected components are used for the classification based on a neural network. The experiment done with live Korean address images has demonstrated the superiority of the proposed method. The correct classification rate for 3,147 testing images was about 98.85%.

  • In this study, the risk factors which derive from the ground condition of typical construction sites are put forward. In order to prioritize the risk elements, the analytical method of AHP was used. The result of using a weighting factor for each risk analysis showed that if the constituency index is less than 0.1, then reliable results and priorities for each of the risk elements can be calculated using the AHP method. From now on, if the range of measured value can be established, the risk or safety value of concrete structures for power lines can be applicable.

  • 본 연구에서는 해부학강의에 있어 혼합강의의 적용가능성을 평가하였다. 2007~2009년 매 1학기동안 강원대학교 의과대학 간호학과 학생(n=143)을 대상으로 해부학강의를 가상강의 9회, 면대면 강의 3회, 사체해부실습 2회로 구성된 혼합강의로 실시한 후 설문을 통해 자기평가요인(만족도, 난이도, 흥미도, 유용성, 평가의 적절성, 학업성취도, 운영의 적절성, 이론실습연계성), 학업성취별 자기평가요인, 자기평가요인간의 상관관계를 분석하였다. 자기평가요인의 난이도는 평균$2.96{\pm}0.63$점으로 전반적인 강의수준은 적절했던 것으로 나타났고 나머지 모든 요소들은 평균 3.82~4.21점 사이로 평가되어 간호학과에서 해부학강의를 위한 혼합강의의 적용이 매우 긍정적인 것으로 나타났다. 학기종료 후 화보한 최종성적을 기준으로 세 그룹(상위, 중위, 하위)으로 나누어 자기평가요인과의 관계를 분석한 결과, 모든 요소에서 통계적으로 유의하지 않았다(p>0.05). 자기평가요인 간의 상관관계는 난이도와 전공연계성의 유용성(r=0.300, p<0.0003),혼합강의의 유용성(r=0.210, p<0.0137), 평가의 적절성(r=0.323, p<0.0001), 이론실습연계성(r=0.216 0.0097)이 높을수록 상관성을 보였다, 만족도, 전공연계성의 유용성, 혼합강의의 유용성, 이론실습연계성에서는 학업성취도를 제외한 모든 요소에서, 흥미도는 난이도와 학업성취도를 제외한 모든 요소에서 유의성 있게 높은 상관성을 보였다. 하지만 학업성취도에서는 평가의 적절성을 제외한 다른 요소에서는 연관성을 보이지 않아 성적과 관련해 영향을 미치는 요소가 없다는 것으로 판단되어지며 본 연구를 위해 도입된 강의구성이 해부학의 균형 있는 학업성취를 유도할 수 있는 수업방식이라 판단되었다. 결론적으로 본 연구를 통해 해부학강의에 있어 혼합강의의 우수한 교육효과를 알 수 있었고, 간호학과만이 아닌 최근 급증하고 있는 의료-보건계열의 다양한 전공자를 위한 적용, 확대로 해부학지식의 질적 향상과 강의수요에 비해 부족한 해부학 전공 교수진들의 교육 부담을 경감할 수 있는 효과적인 교수법으로 활용가치가 있다고 사료된다.
