The purpose of this study was to explore the health and illness concepts of hospitalized preschoolers. The subjects were 52 hospitalized preschoolers from 3 to 6 grade in one general hospital. Data were collected through semistructured interviews by author. this study was conducted from Mar 2, 2000 to Jun. 30, 2000. Data were coded and categorized by content analysis. The results were as follows : 1. Hospitalized preschoolers's answers about health concepts were coded and then classificated to 7 categories(physical well-being, food, powerfulness, exercise, obedience to authority, cleanliness, sleep.) 2. Hospitalized preschoolers's answers about health behavior to maintenance health were coded and then classificated to 8 categories (food, obedience to authority, treatment, exercise, cleanliness, powerfulness, sleep, psychological stability). 3. Hospitalized preschoolers's answers about prevention of illness were coded and then classificated to 9 categories(food, treatment, obedience to authority, powerfulness, emotional stability, psychological stability, exercise, physical well-being, ability of social adaption). 4. Hospitalized preschoolers's answers about cause of illness were coded and then classificated to 3 categories(illness, trauma, food). 5. Hospitalized preschoolers's answers about treatments of illness were coded and then classificated to 9 categories(treatment, rest, emotional stability, sleep, psychological stability, food, obedience, exercise, powerfulness). 6. The levels of health and illness concepts in this sample were higher than those of the physical causality.

Purpose: This study aimed to explore nursing students' experiences of neonatal nursing simulations using peer tutoring. Methods: In this qualitative content analysis study, data were collected using a narrative survey and focus group interviews with 27 third-year nursing students and six fourth-year nursing students from April to May 2022. Content analysis of the collected data was conducted. Results: Four categories-"stabilizing emotionally through each other", "advancing together", "difficulties in relationships", and "hoping to continue"-and nine sub-categories were extracted. The sub-categories "reduced burden" and "gaining confidence" were grouped into the first category, "stabilizing emotionally through each other". The sub-categories "being motivated to learn," "increased learning ability", and "preparation as a process" were grouped under "advancing together", and "attitudes affecting study environment" and "depending on help" were grouped into the third category of "difficulties in relationships". The fourth category of "hoping to continue" had "wanting to supplement for development" and "wanting to participate in different roles" as sub-categories. Conclusion: Based on the results of this study, we expect pediatric nursing practicum education to improve through the active use of neonatal nursing simulation education incorporating peer tutoring.

The purpose of this study is to identify patterns of learner behaviors, conflicting and facilitating factors during collaborative work in an online learning community(OLC). This study further seeks to investigate the difference of learner behaviors between high- and low-performing groups, and conflicting and facilitating factors. The online postings from four groups(19 students) in the spring semester(study 1) and six groups(24 students) in the fall semester(study 2) were analyzed. A coding scheme was generated based on constant comparison using the qualitative data analysis tool, NVivo. The analysis identified 7 categories of learner behaviors in both studies. Among the seven categories, information seeking and co-construction were most frequently observed in both studies. One evident difference between the high- and low-performing groups was that the high-performing groups revealed more incidents of learner behaviors in both studies. In addition, six categories of conflicting factors and five categories of facilitating factors were emerged in both studies. The inefficiency of work category was one of the most frequently observed categories in both studies. Interestingly, the high-performing groups showed more incidents of conflicting factors than the low-performing groups. This study revealed two different types of conflicting factors and there is a need for different moderating strategies depending on its type. Based on the results of the study, effective design strategies for an OLC to facilitate active learning were suggested.

텍스트에 대한 사용자의 접근성을 향상시키기 위해, 이들 문서는 정해진 기준에 따라 카테고리로 분류되어 제공되고 있다. 과거에는 카테고리 분류 작업이 수작업으로 수행되었지만, 문서 작성자에게 분류를 맡기는 경우 분류 정확성을 보장할 수 없고 관리자가 모든 분류를 담당하는 경우 많은 시간과 비용이 소요된다는 어려움이 있었다. 이러한 한계를 극복하기 위해 카테고리를 자동으로 식별할 수 있는 문서 분류 기법에 대한 연구가 활발하게 수행되었다. 하지만 대부분의 문서 분류 기법은 각 문서가 하나의 카테고리에만 속하는 경우를 가정하고 있기 때문에, 하나의 문서가 다양한 주제를 갖는 실제 상황과 부합하지 않는다는 한계를 갖는다. 이를 보완하기 위해 최근 문서의 다중 카테고리 식별을 위한 연구가 일부 수행되었으나, 이들 연구는 대부분 이미 다중 카테고리가 부여되어 있는 문서에 대한 학습을 통해 분류 규칙을 생성하므로 단일 카테고리만 부여되어 있는 기존 문서의 다중 카테고리 식별에는 적용할 수 없다는 제약을 갖는다. 따라서 본 연구에서는 이러한 제약을 극복하기 위해, 카테고리, 토픽, 문서간 관계 분석을 통해 단일 카테고리를 갖는 문서로부터 추가 주제를 발굴하여 이를 다중 카테고리로 자동 확장시킬 수 있는 방법론을 제안하였다. 실험 결과 원 카테고리가 식별된 총 24,000건의 문서 중 23,089건에 대해 카테고리를 확장시킬 수 있었다. 또한 정확도 분석에서 카테고리의 특성에 따라 카테고리 분류 정확도가 상이하게 나타나는 현상을 발견하였다. 본 연구는 단일 카테고리로 분류된 문서에 대해 다중 카테고리를 추가로 식별하여 부여함으로써, 규칙 학습 과정에서 다중 카테고리가 부여된 문서를 필요로 하는 기존 다중 카테고리 문서 분류 알고리즘의 활용성을 매우 향상시킬 수 있을 것으로 기대한다.

One of organization's generic functions is the interpretation of events to carry out decision-making activities. In intelligent Data Interpretation System(IDIS), Interpreting is computationally modeled as classification of new data into categories having similar features. We define the Extensional Object Model(ExOM) as a formalism for IDIS. In ExOM, objects and categories are loosely coupled to provide flexibility for both object description and category definition in data gathering and interpretation process. Objects are classified inductively based on exemplars of categories as well as deductively based on category structures.

This study is concerned with the evaluation of predictive ability of classification models with ordered multiple categories. If categories can be ordered or ranked the spread of misclassification should be considered to evaluate the performance of the classification models using loss rate since the apparent error rate can not measure the spread of misclassification. Since loss rate is known to underestimate the true loss rate the bootstrap method were used to estimate the true loss rate. thus this study suggests the method to evaluate the predictive power of the classification models using loss rate and the bootstrap estimate of the true loss rate.

The main characteristic of the ordinal scale is that its categories have a logically or continuously ordered relationship to each other. A continuous type permits measuring degrees of differences among categories. Also, the specific amount of differences is important. In this paper we consider the scoring method using a dummy variable based on distance among categories.

Recently a construction of local cohomology functors for compactly generated triangulated categories admitting small coproducts is introduced and studied by Benson, Iyengar, Krause, Asadollahi and their coauthors. Following their idea, we introduce the depth of objects in such triangulated categories and get that when (R, m) is a graded-commutative Noetherian local ring, the depth of every cohomologically bounded and cohomologically finite object is not larger than its dimension.

In this paper we study recollements of abelian categories and balanced pairs. The main results are: recollements induce new balanced pairs from the middle category; the resolution dimensions are bounded under certain conditions. As an application, the resolution dimensions with respect to cotilting objects of abelian categories involved in recollements are recovered.
