  • The purpose of this study is to clarify the concept and construct of the problem recognition stage in consumer decision making process of apparel Purchase. This study was supplemented by the theoretical study and field interviews. 40 women were interviewed on their apparel purchase situation to identify problem recognition process. As a result, the concept of problem recognition in apparel purchase is the perceived difference between the ideal state of apparel affairs and the actual situation sufficient to arouse and activate the decision making process. And the problem recognition stage in apparel purchase is constituted of the following steps: gestation, categorization, problem definition, and purchase intention formation. In most cases, these four steps existed, but in some cases several steps were deleted or condensed.

  • The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.

  • Purpose: This study was carried out to identify the effects of classroom lectures on adolescent nursing education in distance education. Method: The design of this study was a quasi-experimental research with nonequivalent control group, pretest-posttest design. The subjects of this study were 434 nurses in K open university. Data were collected from April to June, 2009 by the adolescent delinquency measurement scale and questionnaire for awareness of the issue in adolescent health education. Result: The both groups perceived the biggest problem as the lack of assigned education time in adolescent health education. After receiving education, the experimental group improved significantly more than the control group in recognition of adolescent problem behavior which is in interpersonal, intermaterial, order, drug, sex, position, alcohol/smoking delinquency and psychiatric problem. Conclusion: This adolescent nursing education is an effective education for nurses and could improve their recognition of adolescent problem behavior.

  • Environmental pollution induced by food wastes is considered as one of very serious problems in the world, and it is the most important to reduce the production of food wastes. In this study, environmental campaign for reducing food waste was conducted by applying various campaign methods using such as a bulletin board, intra-network, slogans & posters and news letters, as well as some systems such as penalty and prize in a business & industry foodservice. We investigated customers' recognition and execution degree before and after environmental campaign for the purpose of analyzing the changes of customers' attitude by the campaign. The subjects of this study had generally high level of recognition of environmental problem(3.09 point) compared to the execution degree(1.88 point)(Max. 5 points), implying necessity for the induction of actual execution of food wastes reduction by continuous environmental campaign. After environmental campaign, the recognition of environmental problem related to food wastes was significantly increased from 3.09 point to 3.29 point (p<0.001), and the execution degree for food wastes reduction was also greatly increased from 1.88 to 2.70 point (p<0.001). These changes indicated that campaign for food wastes reduction has raised customers' recognition and execution for environmental protection.

  • 영상 기기의 기계적인 문제로 인해 실험 데이터에 발생한 잡음으로 인한 인식 오류를 최소화하기 위해서 영상복원 과정을 거친다. 영상 복원 방법은 실험 데이터를 구성하는 각각의 픽셀에 대해 Direct Neighbor와 Indirect Neighbor의 개수와 위치를 조사해서 잡음을 해결한다. 결과적으로, 영상 복원 과정을 통해 실험 데이터에 발생한 잡음을 최대한 제거하고, 영역 단위로 학습 데이터와 실험 데이터의 차이를 계산해서 잡음에 의한 인식 오류 가능성을 낮춤으로써 만족할만한 인식 결과를 얻을 수 있다.

  • In this syudy, the researches classifying the artificial and natural flaws in welding parts are performed using the smart pattern recognition technology. For this purpose the smart signal pattern recognition package including the user defined function was developed and the total procedure including the digital signal processing,feature extraction , feature selection and classifier selection is treated by bulk. Specially it is composed with and discussed using the statistical classifier such as the linear disciminant function classifier, the empirical Bayesian classifier. Also, the smart pattern recognition technology is applied to classification problem of natural flaw(i.e multiple classification problem-crack,lack of penetration,lack of fusion,porosity,and slag inclusion, the planar and volumetric flaw classification problem). According to this results, if appropriately learned the neural network classifier is better than ststistical classifier in the classification problem of natural flaw. And it is possible to acquire the recognition rate of 80% above through it is different a little according to domain extracting the feature and the classifier.

  • Emotion recognition is an important component of affective computing, and is significant in the implementation of natural and friendly human-computer interaction. An effective approach to recognizing emotion from text is based on a machine learning technique, which deals with emotion recognition as a classification problem. However, in emotion recognition, the texts involved are usually very short, leaving a very large, sparse feature space, which decreases the performance of emotion classification. This paper proposes to resolve the problem of feature sparseness, and largely improve the emotion recognition performance from short texts by doing the following: representing short texts with word cluster features, offering a novel word clustering algorithm, and using a new feature weighting scheme. Emotion classification experiments were performed with different features and weighting schemes on a publicly available dataset. The experimental results suggest that the word cluster features and the proposed weighting scheme can partly resolve problems with feature sparseness and emotion recognition performance.

  • 본 연구는 유아의 문제행동에 대한 부모와 교사의 인식차이 연구로 유아의 문제행동에 대해 부모와 교사 간 인식차이 분석 결과 유아의 모든 문제행동 유형에 대하여 부모와 교사 간의 인식 차이가 뚜렷한 것으로 나타나고 특히 부모보다 교사들이 문제행동에 대해서 비교적 문제가 있다고 인식하고 있는 것으로 나타났다. 그리고 유아 지도전략에 대한 부모와 교사의 인식 차이에 있어서도 유아의 지도전략에 대해 부모와 교사의 인식에 있어, 반응적 상호작용과 교육기관에서의 예방실제가 선호되는 것으로 나타나 이는 부모보다 교사가 통계적으로 유의미하게 높은 것으로 나타난 반면 사회정서 전략에 있어서는 유의미한 차이가 없는 것으로 나타났다. 이 같은 결과는 원래 유아들의 다양한 문제행동을 통제관리 해야 하는 교사의 입장에서 편중된 지도전략보다 사회 정서적으로 인식되고 있는 공통적 지도전략에 바탕을 두되 교사 유아 간 발생되는 문제행동 유형과 대상유아에 따라 반응적 상호작용하는 지도전략이 선호되고 특히 돌출문제 행동이 많이 발생하는 유아의 행동 특성을 고려할 때 돌출문제 유아의 행동억제와 예방에 중점을 둔 반응적 상호작용 전략과 예방실제 지도전략이 선호되고 있음을 시사한 것으로 평가 할 수 있다.

  • Purpose: The purpose of this study was to explore the influence in a planned pregnancy of alcohol related family variables, knowledge and recognition of the effects of alcohol use during pregnancy on actual alcohol use during pregnancy. Methods: The participants were 284 women who had experienced a pregnancy at some time in their lives. The data were collected from December 2011 to January 2012 and the method of data collection was self-report questionnaires. The instruments for this study were AUDIT-K, Knowledge of alcohol use during pregnancy, and Recognition of alcohol use during pregnancy. Results: There were higher incidences of alcohol use during pregnancy when alcohol consumption was a problem, when there was a family member with an alcohol problem, or after having had an artificial abortion. There was no correlation in alcohol use during pregnancy with knowledge, but a correlation with recognition was found. Conclusion: The results of this study suggest that the main factor in alcohol use during pregnancy is recognition of the effects of alcohol use during pregnancy.
