  • 본고는 학교도서관에서 사서교사가 실시하는 협동수업의 효과적인 수행을 위한 연구에 초점이 있다. 협동수업은 학교도서관을 활용하여 일반 교과 (국어, 영어. 사회, 과학, 국사 등)의 수업을 교과 교사와 사서교사가 협동으로 실시하는 수업이다. 본고는 학교 교육의 중심축인 교육 과정과 교과 수업을 위한 기반 이론인 교수설계 이론 등을 바탕으로 한 협동수업의 모형 개발과 실천 방법을 이론-모형-지원에 의한 3단계로 제시한다.

  • In this paper, we propose a constrained alternating least squares nonnegative matrix factorization algorithm (cALSNMF) to detect active brain regions from single subject's task-related fMRI data. In cALSNMF, we define a new cost function which considers the uncorrelation and noisy problems of fMRI data by adding decorrelation and smoothing constraints in original Euclidean distance cost function. We also generate a novel training procedure by modifying the update rules and combining with optimal brain surgeon (OBS) algorithm. The experimental results on visuomotor task fMRI data show that our cALSNMF fits fMRI data better than original ALSNMF in detecting task-related brain activation from single subject's fMRI data.

  • High unemployment rates repeatedly cause recurring social problems such as fewer employment opportunities and employment insecurity. Following this trend, various programs related to employment have been provided through various government and institutions. However, they have established overlapping policies and programs and there is no one stop gateway to find effective and efficient way to find relevant information. For this purpose, this study aims to provide employment and job search subject gateway development. The study has carried out case studies, literature reviews, and user survey. Based on this study, it suggested a linked metadata model to organize and link scattered information together, and a digital gateway operating diverse information services. It is expected to provide a basis to develop comprehensive information service model for employment.

  • The study presents a global research scenario in the domain of quantum sensing in quantitative and qualitative terms. The study is based on an analysis of 588 global publications in the field, sourced from the Scopus database for the period 1991-2020. The study identified key countries, organizations and authors, network collaborative linkages at national, institutional, and author level. In addition, it identified broad subject areas intersecting quantum sensing research, key journals for research communications, and broad characteristics of highly-cited papers. The study finds that the USA and Germany lead the world ranking in quantum sensing research with a combined share of 50% to the global output. The USA, Germany, and Italy are the home countries to 13 of the top 15 most productive organizations, and also the home countries to 14 of the top 15 most productive authors in the subject. The top journals publishing most research publications are Physical Review A, Physical Review Letters and New Journal of Physics. However, in the most cited journals list in the subject, Agriculture & Forest Meterology, Science and Physical Review A tops the list.

  • The purpose of this study was to identified the level of the exposure to the PC Pornography and what's their post-exposure reactions to the PC pornography. The subjects were 423 middle school boys in Pusan. The survey was executed from July 12 through October 30, 1999. The collected data were analyzed by SPSS WIN using the %, mean, ANOVA. The results of this study were as follows: 1. 79.4%(336 boys) were exposed to the PC pornography. 46.3%(196 boys) answered that they experienced the published pornography prior to the PC pornography. 2. 78.5%(333 boys) answered that they had their PC in their homes. This ratio revealed the higher level of possession. 67.6% said that their PC were set in their own rooms. 57.9% of the subject answered they experienced the Internet Communications. 68.6% of the subject said that they tried PC communications once or twice in a week. 38.5% of the subject expressed that they used their own PC for 1-2 hours in a day. Most of them(82.7%) enjoyed the PC games or entertainment programs. 81.3% of the subject answered that their school performance didn't show the progress after the use of their own PC. 78.3% of the subject answered that they acquired information. 45.2% of the subject answered that they made their friend through the Internet communications. 78.7% of the subject answered that the time of family dialogue decreased. 70.7% of the subject answered that the time of their TV watching decreased. 3. As for their post-exposure reactions the subject who were exposed to the PC Pornography showed the point 2.93 in the item 'pleasure'. The point of 'sexual impulses' was 2.81. But the point of 'anxiety' was 2.75, the point of 'dislike or disgust' was 2.62, the point of 'guilty' was 2.59. 4. According to the frequency, the motivation and the companionship on the exposure to PC Pornography, their post-exposure reaction scores showed differences significantly. Finally, the post-exposure reaction had relation to the frequency, the motivation, the companionship and the place (F=3.28 ~ 8.40, p=.012 ~ .000).

  • 우리나라 대학도서관에서 정보서비스의 수준을 높이기 위하여 필수적으로 요청되는 것이 정보서비스의 주체인 정보사서의 질을 높여야 한다는 이론을 규명하기 위하여, 우러나라 대학도서관의 정보서비스 현황과 정보사서의 현황을 통계적으로 상세히 분석하였다. 그 결과, 우리나라 정보사서들은 도서관학사학위를 소지한 20대와 30대의 인사들로 주성되어 있었으며, 주제전문사서로 볼 수 있는 비율은 7.6%에 불과했고, 즉답형 질문(42.1%)과, 지시형 질문(32.7%)을 주로 해답하여 주며, 정보서비스의 수준을 향상시키기 위하여 주제전문사서제도를 채택하는 것이 절대 바람직하다고 응답하였다. 주제전문사서가 수행하여야 할 주요 기능은 특정주제분야의 정보서비스, 서지, 안내서, 도서목록, 색인, 초록등의 작성; 정보배포와 최신정보주지 서비스; 균형있는 장서구성; 학과단위, 학생 및 교수와의 긴밀한 교량적 역할; 독장에 대한 자료 및 도서관 이용의 정규 비정규직인 강의와 안내; 및 분류편목의 순서라고 응답하였다. 주제전문사서를 양성하기 위한 가장 좋은 교육제도는 도서관학사를 하여금 대학원에 진학하여 주제전문가로서의 소양을 쌓도록 하여 도서관학석사학위를 수여 하는 것이 바람직하다고 분석되었으며, 주제전문사서제도가 확립되어야만 대학사서의 교수신분을 확보할 수 있다고 보았다.

  • In this study, the SCAMPER method which is a creative thinking method is applied in the food and beverage class of a specialized high school NCS study module to enhance creative thinking and investigate the influence on learning motivation of students. For verification, 10 sessions of 50 minutes classes were performed on 1, 2 grade students in H high school located in Gyeonggi-do Yangju City from August to November 2015 subject to 54 subjects in the experiment group and 54 subject in the control group. To look into the influence of the NCS food and beverage practice class using the SCAMPER method on learning motivation, pre post survey investigation was conducted on the students for measurements through surveys to deduct conclusions. As a result, it was verified that the NCS food and beverage practice class using the SCAMPER method had positive influence on the learning motivation of specialized high school students and positive change was also found in the awareness of SCAMPER method using classes and creative activities in the students. In this study, the influence of the NCS food and beverage practice class using the SCAMPER method on learning motivation subject to specialized high school students is investigated to have meaning as data to expand the research range of NCS food and beverage practice education.

  • This study suggests an alternative to the conventional collaborative filtering method for predicting consumer choice, using case-based reasoning. The algorithm of case-based reasoning determines the similarity between the alternative sets that each subject chooses. Case-based reasoning uses the inverse of the normalized Euclidian distance as a similarity measurement. This normalized distance is calculated by the ratio of difference between each attribute level relative to the maximum range between the lowest and highest level. The alternative case-based reasoning based on similarity predicts a target subject's choice by applying the utility values of the subjects most similar to the target subject to calculate the utility of the profiles that the target subject chooses. This approach assumes that subjects who deliberate in a similar alternative set may have similar preferences for each attribute level in decision making. The result shows the similarity between comparable alternatives the consumers consider buying is a significant factor to predict the consumer choice. Also the interaction effect has a positive influence on the predictive accuracy. This implies the consumers who looked into the same alternatives can probably pick up the same product at the end. The suggested alternative requires fewer predictors than conjoint analysis for predicting customer choices.
