  • 본 연구는 2단계 학습자 개별 적응 평가시스템을 설계하고 구현한 것이다. 2단계 학습자 개별 적응 평가시스템이란 학습자의 학습 상태에 따라 필요한 문제지를 추출하여 동적으로 제공할 수 있도록 단원별 진단평가를 시행하고 학습된 결과를 저장하였다가 그 결과에 따라 기본, 보통, 심화 문제지군(群)을 구성하여 제공하는 단계형 학습자 개별적응 평가(CAT)를 설계하여 구현한 평가 시스템을 말한다. 본 학습자 개별 적응 평가시스템은 웹을 기반으로 하였으므로 지역적으로 흩어져 있는 교사들이 공동으로 문항을 제작함으로써 문항제작에 필요한 노력을 줄일 수 있고 학습자는 이를 이용해 개별학습의 효과를 얻을 수 있다.

  • A new mixed-effects model was developed that predicts individual-tree total height for Pinus densiflora trees in Gangwon province as a function of individual-tree diameter (cm). The mixed-effects model contains two random-effects parameters. Maximum likelihood estimation was used to fit the model to 560 height-diameter observations of individual trees measured throughout Gwangwon province in 2007 as part of the National Forest Inventory Program in Korea. The new model is an improvement over fixed-effects models because it can be calibrated to a local area, such as an inventory plot or individual stand. The new model also appears to be an improvement over the Forest Resources Evaluation and Prediction Program for the ten calibration trees used in this study. An example is provided that describes how to estimate the random-effects parameters using ten calibration trees.

  • Purpose: The purpose of this study was to review and identify factors relevant to workplace bullying in nursing. Methods: Twenty-three studies that met the criteria were selected from a sample of twenty-six studies. These articles were retrieved from a central literature databases (N=13,241). The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. A funnel plot inspection (similar to scatter plot) with a trim-and-fill method was used to assess the publication bias of the meta-analyzed studies. Results: From the systematic review, fifty-one factors were identified as having an influencing effect. Fourteen factors (five individual and nine organizational factors) were eligible for meta-analysis. The individual factors included, self-esteem (ESr=-.31), psychological capital (ESr=-.26), and marital status (ESr=-.06) which were significantly correlated with workplace bullying. Organizational factors included, organizational tolerance (ESr=.48), supervisor incivility (ESr=.47), job stress (ESr=.46), group morale (ESr=-.36), group support (ESr=-.35), supervisor leadership (ESr=-.35), group identity (ESr=-.33), and structural empowerment (ESr=-.27). These factors were significantly correlated with workplace bullying. There were no publication biases except for both individual and organizational factors. Conclusion: Organizational factors have more of an greater impact than individual factors on workplace bullying. The results of this study support the need for intervention at the organizational level.

  • This study proposed that a relationship exists between individual emotions and knowledge sharing (KS) intentions in competitive online advice communities. Through statistical analysis of 220 valid questionnaires collected from qualified community members, we found that individuals' intentions to contribute knowledge were enhanced by playfulness and reciprocity, while their intention to seek knowledge from others was facilitated significantly by needs fulfillment, sense of competition, and playfulness. In addition, we found that playfulness was a common factor that affected the intention to seek, as well as to contribute, knowledge. Specifically, playfulness was a highly significant individual emotion that affected both individuals' intention to contribute and seek knowledge, while reciprocity was significant primarily in individuals' intentions to contribute knowledge. Needs fulfillment and sense of competition were significant emotions that affected primarily individuals' intentions to seek knowledge. Interestingly, the factors that affected the intention to seek knowledge were consistent both in all participants and in the high-level fear group. However, in the low-level fear group, playfulness influenced KS intentions.

  • 정보통신기술의 발달로 인터넷을 이용하는 패션/코디 쇼핑몰은 그 시장이 매년 큰 폭으로 증가하고 있다. 하지만, 자신의 신체나 패션스타일에 맞는 의류를 온라인 쇼핑몰에서 검색하는 것은 쉽지 않다. 본 논문은 여성 의류의 패션/코디 추천시스템에 대하여 특히, 개인의 신체적 특성에 가장 잘 맞추어진 의류 추천기능에 대하여 논한다. 또한, 계절별 유행에 대한 전문가의 추천도 고려할 수 있고, 자신의 좋아하는 의류스타일도 미리 등록해 둔 후에, 다양한 방법의 선택을 통하여 등록된 상품 중 자신이 원하는 최적의 상품을 추천받을 수 있도록 패션/코디 쇼핑몰에서의 추천방법을 제안하였다.

  • This paper aims at estimating consumer surplus for recreational sea fishing in Tongyeong coastal area using individual travel cost method. A Poisson model (PM), a negative binomial model (NBM), a truncated Poisson model (TPM), and a truncated negative binomial model (TNBM) are applied for individual travel cost method in order to account characteristics of count data (non-negative discrete data.) The survey was conducted for 462 inshore anglers using personal interview method in Tongyeong during July and October 2007. Respondents were asked about how often they do fishing, travel costs, catch, income, and so on. Because of over-dispersion problem in PM and TPM, NBM and TNBM were considered to be more appropriate statistically. All parameters estimated are statistically significant and theoretically valid. As the results based on TNBM, consumer surplus per trip was estimated to be 183,486 won, total consumer surplus per person and per year 3,399,658 won, and the marginal effect of consumer surplus on % changes in catch rate is 185,372 won.

  • This study attempted to determine the effects of a cooperative and cognitive group therapy compared to individual therapy in 24 aphasic subjects. Two dependent variables were measured overall language performance, functional communication skills. 18 subjects with different types and severity of aphasia participated in the group therapy. 6 aphasic subjects participated in the individual therapy and they functioned as a control group. The subjects were ranged from 27 to 59 years in age. The group therapy using the cooperative learning utilized the following procedures. First, 6 aphasics constituted 1 group where each subject peformed a task and they monitored one another. Second, 2 aphasics consisted 1 group and they cooperated to perform a task. Third, 3 groups with 2 aphasics in a group competed one another in a task where the 2 aphasics had to cooperated. Finally, the investigator gave the feedback to the group and she and the subjects discussed the overall procedures of the therapy. The above mentioned 2 tests were administered pre- and post-treatment. A repeated two-way ANOVA was performed for analysis. The results showed that the group therapy was more effective in improving overall language performance as compared to the individual therapy. And, the group therapy was more effective in increasing functional communication skills as compared to the individual therapy.

  • This study examines the role of perceived feedback and motivations on the use for contribution in Knowledge Management Systems (KMS). An individual expects responses from others when he or she posts the knowledge or questions of soliciting knowledge in KMS. If an individual posts a message and there are many responses, motivation to use KMS will develop. Prior research has considered feedback a potential factor that would affect an individual's motivation, such as self-efficacy, but there is few prior works that have tested empirically on how feedback can influence an individual's motivations as well as the use for contribution in KMS. Perceived feedback can be categorized into feedback on posted knowledge and feedback on knowledge request postings. The results of the study show that motivations such as organizational reward, knowledge self-efficacy, and enjoyment of helping, except for social reward, are associated with the use for contribution. Our results also show that among perceived feedback, feedback on posted knowledge affects motivation and use for contribution while feedback on knowledge request postings directly influences the use for contribution.
