  • The purpose of this study is to analyze scope and sequence of undergraduate curricula in the department of physical education. For this purpose, this paper has used the types of undergraduate subjects, which are based on analysis tools on the scope and the sequence of the Department of Education major curriculum by Kim and Lee(2005). The major results of this study were as follows. First, the proportion of major content knowledge is far more pedagogical content knowledge. Second, the scope of Physical Education major curriculum is too much stressed on 'the subjects of major content' and on 'the subjects of specific area' than 'the subjects of major skills' and 'comprehensive problem solving'. Third, the Physical Education major curriculum has shown the specific sequence; introduction/foundation courses and theory courses, application courses orderly. Whileas, application course and synthesis course are slim to none.

  • The objective of this study is to investigate actual conditions of terrestrial vegetation part in Environmental impact statement, and to prepare a proposal for the efficiency of Environmental Impact Assessment. 13 E.I.S.s made out during 1996.6-1997.5. have been chosen and analysed with respect to scope of survey, item of survey, method of survey, and result of survey. Actual conditioins of terrestrial vegetation part in E.I.S. are summarized as follows : 1. The mean number of total participants in drawing up E.I.S. is 26.0 persons, that of participants in terrestrial vegetation part is 2.3 persons. 2. In case of planar project, the mean of scope of survey is 16.1 times as large as area of project . In case of linear project, the scope of survey has been determined arbitrarily. 3. The most part of survey has been dependent on literature, and field survey has been practically neglected. 4. Results of survey mostly missed the point that E.I.A. pursues. And proposals are as follows : 1. Participants in terrestrial vegetation part in drawing up E.I.S should be increased. 2. It is necessary to subdivide scope of survey in view of difference between planar project and linear project. 3. As for item and method of survey, field survey should be specially reinforced. 4. Several sheets of map as results of survey should be included in E.I.S. The vegetation map, the D.G.N. map, and the planting map should be included and drawn by smaller scale as possible.

  • This study compares experienced and inexperienced consumers' patterns in cue utilisation in product evaluations in the arts market. Borrowing the notion of high- and low-scope cues introduced by the cue-diagnosticity framework, we differentiate between the two most readily discernible extrinsic cues in the fine arts market - an art gallery's brand reputation (a high-scope cue) and certificates of authenticity (a low-scope cue). These two cues are different in nature; the former is more abstract, intangible, and rich in content, so is more difficult to interpret than the latter. Given the differences in experienced and inexperienced consumers' information processing styles, we hypothesise that experienced arts consumers form perceived credibility of and purchase intentions towards artworks based on high-scope cues, whereas inexperienced consumers do so based on low-scope cues. To test our hypothesis, we conducted a consumer intercept study at Korea's two most representative art fairs. The survey participants were categorised into either experienced or inexperienced consumers based on their prior purchase experience, and their responses to a set of attribute combinations about two artworks created by the same artist were collected. The results indicate that experienced participants show higher purchase intentions when an art gallery's reputation is very high, whereas inexperienced participants show higher purchase intentions when artworks are accompanied by certificates of authenticity. This congruency effect between prior experience and cue type is mediated by the perceived credibility of the artworks. The findings suggest a correspondence between a consumer's prior experience and the types of extrinsic cues that are important in product evaluations. To the best of our knowledge, this study is the first attempt ever to investigate the role of prior experience in determining when to use high- or low-scope cues. It also provides a useful frame of reference to advise marketers on the effective sales approach based on a client's prior purchase experience.

  • 본 연구에서는 UAV (Unmanned Aerial Vehicle)와 PlanetScope 위성영상을 함께 이용한 붕괴건물 탐지를 수행하여 지표면에 위치한 특정 객체 탐지에 있어 이종 센서의 활용 가능성을 제시하였다. 이를 위해 지난해 4월 산불 피해로 붕괴된 20여 채의 건물들이 있는 곳을 실험장소로 선정하였다. 붕괴건물 탐지를 위해 1차적으로 객체기반 분할을 수행한 고해상도의 UAV 영상을 이용해 ExG (Excess Green), GLCM (Gray-Level Co-occurrence Matrix) 그리고 DSM (Digital Surface Model)과 같은 객체들의 특징(feature) 정보를 생성한 후 이를 붕괴건물 후보군 탐지에 이용하였다. 이 과정에서 탐지정확도 향상을 위해 PlanetScope를 이용한 변화탐지 결과를 함께 사용하였으며 이를 시드 화소(seed pixles)로 사용하여 붕괴건물 후보군에서 오탐지된 영역과 과탐지된 영역을 수정 및 보완하였다. 최종적인 탐지 결과는 참조 영상을 통해 그 성능을 분석하였으며 UAV 영상만을 이용한 붕괴건물 후보군 탐지 결과와 UAV 그리고 PlanetScope 영상을 함께 사용했을 때의 결과의 정확도를 비교, 분석하였다. 그 결과 UAV 영상만을 이용해 탐지한 붕괴건물의 정확도는 0.4867 F1-score를 가지며 UAV와 PlanetScope 영상을 함께 사용했을 때의 결과는 0.8064 F1-score로 그 값이 상승하였다. Kappa 지수 또한 0.3674에서 0.8225로 향상된 것을 확인할 수 있었다.

  • Why should quantifiers float\ulcorner This is the question that this paper sets out to answer. In the past, research concentrated on how the theory should account for the non-constituency of a quantificational determiner and the NP it quantifies over. Successful as they might have been, those theories have little, if anything to offer as an answer to the question why quantifiers would float. Here we sketch a theory that puts the scopal properties of FQs (already observed by Dowty and Brodie, 1984) in the center of their properties. We construct a theory in which FQs are simple scope markers and float when differential scope needs to be marked.

  • Percutaneous endoscopic gastrostomy (PEG) is a common method for providing long-term enteral nutrition to patients. PEG tube placement and removal are relatively safe; generally, a PEG tube can be removed using gentle traction, and excessive bleeding is rare. The over-the-scope clip system is a new device that can be used for gastrointestinal hemostasis and for closing gastrointestinal fistulae. In the present case, a 68-year-old male patient had to remove the PEG tube because of persistent leakage around the PEG tube. Although it was gently removed using traction, incessant bleeding continued, with a Rockall score of 5 points, even after hemocoagulation was attempted. An over-the-scope clip device was used to achieve hemostasis and fistula closure.
