주관식 평가는 객관식보다 높은 수준의 인지 능력을 측정할 수 있으나 채점의 객관성과 신뢰성의 문제, 그리고 한국어 처리의 어려움으로 기피하여 왔다. 본 논문은 이와 같은 문제를 해결하기 위해 한국어의 구문정보와 격의미 정보를 이용하여 주관식 문제의 답안을 채점하는 시스템을 설계, 구현하였다. 이 시스템은 채점의 시간과 노력을 덜고 채점의 객관성을 획득할 수 있다. 시스템의 실험 결과 75%에 달하는 성공률을 얻을 수 있었고 본 시스템을 이용하여 학생의 답지 가운데 정답에 해당하는 답지를 찾는 정보검색의 관점에서 시스템을 평가한 결과 단어추출방법을 이용한 시스템보다 재현율과 정확률의 개선을 얻을 수 있었다. 이 시스템은 앞으로 주관식 채점 방법의 기초가 될 것으로 기대된다.

Purpose: This study investigates dental health and chewing ability of patients hospitalized in geriatric hospital, and compares the chewing ability for each factor that can be used as data for dental healthcare of senior citizens and basic data for denture insurance for the elderly. Methods: The 101 subjects of this study were selected from 178 patients hospitalized in a geriatric hospital located in Daegu Metropolitan City, excluding 77 patients who were being treated in the intensive care unit and who were unable to communicate. The chewing ability of the patients were measured using an evaluation scale based on foods consisting of 10 different hardnesses. Results: Patients with less than 21 teeth, those with dentures and patients who were less than satisfied with their dental conditions had difficulties in chewing hard food such as dried squid and radish kimchi, and the Chewing ability increased proportionally to the number of remaining teeth(p<0.001), appropriateness of the maxillary and mandibular dentures(p<0.005) and the level of dental satisfaction(p<0.001). Conclusion: This study is limited as the subjects were selected from a single hospital and the authors estimate that various studies will be necessary to investigate the Chewing ability of patients hospitalized in long-term hospitals. The subjects of this study did not receive any dental treatment while staying in the hospital and many of the subjects had bad fit denture or didn't have dentures or did not use dentures, although they have dentures, which calls for denture construction and prosthetics through dental treatment.

A functional ability and adequate nutritional status are the major determinants of health status, Self-rated health (SRH) is a worldwide method to assess health status and it is recognized as a predictor of morbidity and mortality in the elderly, This study was designed to evaluate the functional ability and nutritional risk according to SRH in the elderly. Four hundred nine free-living elderly people (118 male, 291 female), aged $\geq$ 65 years were interviewed by trained interviewers using structured questionnaires including demographic information, SRH, anthropometric measurements, functional ability, general health status, and nutritional risk. SRH was divided into three status such as “Good”, “Moderate” and “Poor” status. And all the data were analyzed by oneway ANOVA, spearman correlation, and x$^2$ analysis using SPSS 9.0 version at p 〈 0.05. Of all the subjects, 48.9％ perceived their health status as “poor”, and their functional abilities (activities of daily living, instrumental activities of daily living) were more impaired than their counterparts (“good” and “moderate”). Poor self-rated health was also related to: a higher prevalence of illnesses (p 〈 0,001) especially in hypertension, arthritis. Self-rated health was significantly related to food security (p 〈 0.001), food enjoyment (p 〈 0.001) ,and nutritional knowledge (p = 0.0 13). Also NSI checklist total score was the highest in “poor” health status (p 〈 0.001). Better self-rated health was related to better food security, and better food enjoyment. However, smoking, alcoholic intake, exercise, eating behaviors, and demographic characteristics were not significantly different among the three SRH status. SRH was closely related to chronic diseases, functional ability, and nutritional risk in the elderly. Therefore, public health strategies for the elderly should be focused on the elderly who are “poor” in SRH, to improve nutritional status and functional ability, and to reduce risk factors of chronic diseases.

Background: Korea has shown a rapid pace of aging and has become an aged society in a shorter period than Western countries. Therefore, it is important that middle-aged workers maintain their ability to work in the industrial field at the maximum level while maintaining their health. The purpose of this study was to analyze the factors affecting work ability and to use this data to maintain the working ability of middle-aged workers in the future. Methods: From 2015 to 2017, we surveyed 371 street cleaners who visited a health center for health promotion in a metropolitan city. The relationship between the general characteristics of the survey subjects and the Work Ability Index (WAI) was confirmed by a univariate analysis. Statistically significant (p<0.2) factors were selected and a multiple linear regression analysis was conducted with WAI scores as a dependent variable. Results: Age, body mass index, body fat percentage, the Alcohol Use Disorders Identification Test-Korea (AUDIT-K) scores, the Psychosocial Well-Being Index-Short Form (PWI-SF) scores, maximal oxygen consumption ($VO_{2max}$), and hypertension showed statistically significant correlations with the WAI in the univariate analysis. In the multivariate analysis, the $VO_{2max}$, AUDIT-K scores, and PWI-SF scores were included in the regression equation. $VO_{2max}$ had the greatest effect on the standardization coefficient indicating the relative contribution of independent variables, followed by the AUDIT-K scores and the PWI-SF scores. Conclusion: Programs to increase workers' physical work ability and alleviate psychosocial stress and drinking habits should be developed and implemented in the future.

In this paper, an activity-oriented usability model is proposed. The usability model contains two types of characteristics: special-type characteristics of usability and sub-characteristics of usability. Workability, study-ability, and playability are, but do not exhaust, examples of special-type characteristic of usability. They correspond to working, studying, and playing using the software product, respectively. They represent the goal of using and can overlap each other. They are usability too by themselves. Navigate-ability, data-prepare-ability, data-input-ability, response-wait-ability, output-examine-ability, and output-utilize-ability are typical examples of sub-characteristics of usability. They correspond to navigating, preparing data, inputting data, waiting response, examining output, and utilizing the output data, respectively. They are not usability by themselves. They constitute usability together as a group. Assessing is the fundamental and indispensable aspect of quality. Without assessing, the concept of quality has little practical value. Satisfaction, effectiveness, and efficiency are the most typical sub-characteristics of usability in existing quality models, which correspond to the evaluation criteria of usability. In the activity-oriented usability model, however, only the user's satisfaction is included: Satisfaction is regarded as the operational definition of usability in the user's view. As the result, usability can be interpreted as the 'goodness for using, which is evaluated by the user. 'Three fundamental principles regarding software quality models are proposed too in this paper: Principles of Parsimony, Cohesiveness, and Inheritance. Discussions illustrate well that typical existing usability models violate these basic principles. Many authors have tried to define general usability models which can be applied to most kinds of software. The dream of the general and universal usability model, however, may be an illusion. The activity-oriented usability model is expected to serve as a prototype from which specialized usability models can be derived.

본 논문에서는 역량 중심의 교육 흐름에 맞추어 핵심 역량을 살펴보고, 초등학교 실과와 중학교 정보 교과의 2015 개정 교육과정을 핵심 역량으로 분석하였다. 그 결과, 초등학교 실과 교육과정에는 정보처리 활용 역량이 모든 성취기준 및 학습 목표에 잘 반영되어 있었으며, 문제해결과 창의·융합 역량을 기르기 위한 내용도 잘 반영된 것으로 나타났다. 그리고 중학교 정보 교육과정에는 초등학교와 마찬가지로 정보처리활용 역량이 거의 모든 학습요소에 나타났으며, 프로그래밍의 과정에서는 창의·융합 역량 및 협동 역량을 기를 수 있는 교수·학습방법이 주 되게 나타났다. 그러나 자기관리 역량을 기를 수 있는 학습 요소는 적게 포함되어 있는 것으로 확인되었다. 이에 따라 본 논문에서는 SW 교육과정 설계에 있어서 협동 역량, 자기 관리 역량, 의사소통 역량을 더욱 증진 시킬 수 있는 학습 요소와 교수·학습 활동 및 평가 내용이 포함될 것을 제안하였다.

디지털드로잉 과목은 최근 혁신 교육과정의 움직임에 따른 평가 요소들의 세분화 단계와 평가의 점진성이 요구 되어진다. 본 논문에서는 드로잉을 평가하기 위한 혁신기준제시와 루브릭 평가에 의한 제안을 목적으로 한다. 본문에서는 혁신평가 기준으로서 초급 평가의 기준은 기술적 솜씨인 선의 정확성과 일관성, 그림의 비율과 균형 유지이며, 중급에서의 다양한 브러시와 도구를 효과적으로 활용한 능력을 위주로 제안을 하였다. 고급 평가 부분에서는 AI 자료 수집과 창의성을 중심으로 한 새로운 시각이나 독창성 및 주어진 주제에 대한 독특한 관점이나 해석의 부분이다. 아울러 디자인 원칙 이해로서 레이아웃, 색상, 형태 등의 디자인 원칙을 통한 작품의 일관성과 조화와 표현력, 감정 전달을 통한 디지털 드로잉 소프트웨어의 다양한 기능을 적극적으로 활용한 능력을 중심으로 한 완성도에 관한 평가 부분을 도출하였다. 루브릭 평가도입의 중요성은 교수자에게는 객관적이고 일관된 평가를 가능하게 하며, 이러한 예술 과목에서의 루브릭 평가 연구의 핵심은 학습자의 강점과 약점을 명확하게 파악할 수 있도록 도와주고, 학습자는 각 항목에 대한 피드백을 통해 개선할 부분을 파악하며, 그에 따라 더 나은 혁신의 드로잉 기술을 발전시킬 수 있기에 학문적 연구가 필요한 주요 항목이라 하겠다.
