We compared and analyzed the factors affecting the lecture evaluation of IT subjects, which are mandatory for all students of H University. The purpose of this study is to determine whether lecture satisfaction has a significant correlation with academic achievement, attendance rate, and categories of courses. In this study, we check whether the lecture satisfaction of IT liberal arts subjects that require a lot of computer-based practice differs from that of other liberal arts subjects. We used the 2,149 evaluation data of 12 lectures submitted by 2,322 students in the first and second semesters of year 2019 at University H. As for the lecture evaluation results, in addition to the evaluation scores of the multiple choice questions, the subjective questions were also quantified by classifying the statements submitted by the students into positive and negative types to make the results of the lecture evaluation objective. Our research results show that student group who have the higher attendance rates and academic achievements have higher level of lecture satisfaction and they also use more positive words than negative words in subjective evaluation questions. Students with the lower score use the more negative words, but the ratio between positive and negative words does not differ between groups. Higher attendance rates groups in the basic programming courses and software applications courses have higher lecture satisfaction ratio. But in the intermediate programming courses, the higher attendances rate and the lecture satisfaction do not have any significant relationship. Also students in the intermediate programming courses use more negative words than those in the basic programming courses.

Objectives : The middle school students'life style were studied with focus on Body Mass Index(BMI). Information was collected during 1st June 2009 to 10th July from 397 students(both male and female) by the subjective survey centered on personal characteristic, understanding about health in general, everyday activities, eating habits, preference in food, understanding about diet and obesity, and thoughts about fitness and diet. Methods : Students were selected from six classes by convenience sampling, then the final analysis was performed on 397 self-administered questionnaires, excepting 5 questionnaires, which have insincere answers. The data collection was carried out by SPSS(V.14.0 English Version), and the data was verified by $x^2$-test, ANOVA, multiple regression analysis. Results and Conclusion : The survey subjects were in the following distribution of body weights - underweight: 63.6%, normal weight: 29.5% and 6.9% were overweight. There was significantly different between BMI and mothers' occupation and satisfaction with school life(p<0.05). As for the analysis(multiple regression analysis) on understanding about health, the factors that affect BMI are self recognition of figure and efforts to reduce weight. In terms of efforts for one's own health, 78.2% of under weight and 82.3% of normal weight were taking active initiatives. But 85.2% of the overweight students were not giving any efforts. As for the free time activities, more than half answered, 'playing with computers'(48.4 - 66.7%, 1.57 hours on average). As for TV, on average, 2.03 hours were spent in overall. And it turned out that the overweight students spent more time watching TV by 46.49 minutes(0.77 hours) on average(p<0.05). 7.4 hours was the average sleeping time. As for the eating habit,'quantity of meal, snack, meal between meals, fat reduction, and supplementary food'were shown to be related to the BMI(p<0.05). The instant food, meat and sweet food were shown to be also related to the BMI. In terms of knowledge about overweight and diet, only 8 students(2% of the total) answered all 10 questions correct. On average, 7-8 questions were correctly answered(53.9 %). When the scores were analyzed against the BMI by classifying the scores to high, middle and low categories, it showed a relationship by different weight group(p<0.02), and the overweight students had higher score by 0.82 compared to the underweight students. When thoughts and attitude on fitness and diet were analyzed in relationship to the BMI, the result was only - "I try to eat fruits more often"(fruits)(p<0.00).

The purpose of this study is to investigate the teaching methods of prediction, inference, and hypothesis. The major data source was gathered by in-depth interview of science teachers (about 50-80 minutes for each interview). The interviews were conducted using semi-structured interview protocol, which consisted of three major parts: (1) Teacher's definition of prediction, inferences, hypothesis, (2) Teaching methods of prediction, inferences, and hypothesis and (3)Reasons of teacher's inaccurate perceptions of prediction, inference, and hypothesis. All the interviews were audio-taped and transcribed. Topics in the questions were categorized. The results were as follows: Teachers recognized the importance of prediction, inferences, and hypothesis. But they didn't have an accurate conception and they have great difficulty in classifying and explaining the prediction, inferences, and hypothesis. To find out the teaching methods, researcher investigated the inquiry activities, teaching times, usage of terms, teachers' questions, and teaching difficulties. Reasons for having difficulty were lack of teaching competency, difficulties from the students, and problems in the present curriculum. Finally, we discovered that the reasons for teacher's inaccurate perceptions of prediction, inference, and hypothesis were two factors. One is internal factors, which include the lack of scientific inquiry process skills, burdens of science subject and lack of science education knowledge. The other is external factors, which include education system for evaluations and lack of teacher education. In conclusion, this study suggested establishing more elementary teacher education programs that include strengthened concepts of inquiry process skills and teaching methods.

This study explored elementary school teachers' perspectives on science inquiry teaching. First, an open-ended questionnaire was administered to elicit teachers' experiences of their approach to inquiry teaching. These self-reported approaches revealed three conceptions of teaching for inquiry learning in science: 'science process skills-centered' category focused on observing, classifying, measuring, and fair testing; 'generating scientific questions' category focused on students' question-generating; and 'illustrate concept and/or content' category focused on science content demonstration by making use of experimental procedures to obtain expected results. Second, teachers were asked to place 18 activity cards either close to or further from an 'inquiry-based science classroom' card. The relative distances from the activity card to the central classroom card were measured. The teachers perceived that students' activity of 'designing and implementing appropriate procedures' was the most important in supporting an inquiry-based science classroom. Understanding teachers' views has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development.

This study, through the cases occurred in mathematics pencil-paper test, after analyzing the types and the factors of misunderstanding, was to seek to pursue the alternatives to diminish the misunderstanding caused in paper test. When classifying misunderstanding shown in pencil-paper test, four types are found - unsuitable edit, unsuitable organization, formal/typical habits, and unsuitable question situation. One Way, considering accomplishment rate based on existence and nonexistence of misunderstanding factors, the testing paper, that is, type A with misunderstanding factors, showed that the accomplishment rate is 10 percent below the testing paper, type B excluding misunderstanding factors. Also, after distinguishing only items including misunderstanding factors, in comparison with the accomplishment rate, the results showed about 22% difference. And in the type of misunderstanding factor, when system was unsuitable, the degree of misunderstanding appeared seriously. The more complicated many types were, the higher the number of misunderstanding cases appeared. Based on these study results, the conclusions are the followings : First, teachers should try to develop examination papers for exact evaluation. Second, teachers, while students are solving the questions, misunderstanding recognize what are the misunderstanding factors they feel. Third, in the pencil-paper evaluation, the work that teachers should consider importantly, is to analyze students' thought process. Fourth, teachers should try for smooth communications with students.

In this study, on the basis of the seventh national mathematics curriculum, the achievement standards were developed to specify the objectives and contents of teaching-learning and the assessment standards were also developed to differentiate students' levels of achievement at school mathematics. The achievement standards were developed on the following guidelines; 1) to present the minimum standards based on the national curriculum, 2) to develop the standards based on the order of curriculum, 3) to suggest the minimum but ultimate achievement target, 4) to comprise not only of the intellectual but also of psychological spheres such as knowledge, function, attitude, aptitude, etc., and 5) to suggest the standards comprehensively and concretely. The standards were developed on the basis of the middle areas of contents of the curriculum in order not to be too comprehensive, nor to be too detailed. Learning activities, on the other hand, were provided for the assistance of instructions with emphasis on creativity rather than on the routine instruction. The assessment standards were established based on the following principles; 1) to establish the assessment methods, contents, and situations which are to be used for assessment, 2) to establish the criteria of classifying the assessed into the upper, intermediate and lower levels, 3) to develop the assessment standards in a proportionate balance to achievement standards, 4) to establish the intermediate level as a standard, and 5) to establish the minimum level in the contents, concepts, values and attitudes of basic learning. This study also suggested the exemplary test items including short-answer and open-ended questions while putting emphasis on students' real performance to increase their ability in solving problems rather than in calculating. In addition to the test items, it introduced the grading system developed to grade the items with concrete guidelines and to report students' achievement on doing mathematics.

The problem addressed by this study was to reveal what people of Korean rural villages think about the cause, treatment and prevention of illness. The purpose was to contribute to the building of a concept of health toward the development of Korean Nursing Theory. Subjects were residents of five districts among four counties in a farming area of Chonbuk province recommended by health workers as appropriate informants. They were interviewed in their homes, using ethnoscientific methods developed in anthropology. The research tool consisted of open questions developed through the literature and preliminary exploratory interviews. Data were analyzed by classifying each concepts of cause, treatment and prevention of illness or illness symptoms collated by frequency and percentage. The causes of illness are conceived as primarily concrete physical and natural, for examples, overeating, lack of energy, changes in the season and extreme temperatures. Compared to others studies, few supernatural causes related to traditional view of illness were identified. Concepts of the treatment of illness included formal treatments used by modern western or oriental physicians and traditional therapists. But folk medicine used by traditional healers or by the family in the home was most prevalent. The concept of illness prevention originated in the concept of the cause of illness, thus primarily physical and natural, for examples, nutritious food, limiting the amount of food, avoiding becoming cold. When the concept of illness of rural Korean is researched from a sociocultural aspect, the traditional views of an evil cause of ill health and treatment by supernatural methods is not found to be prevalent but folk medicine still occupies a large place in treatment which si often a complex mixture from many mysterious sources. The significance of this study lies in the fact that ethnonursing research can contribute basic data toward the development of Korean nursing theories. Modern western medical concepts have not been accepted unconditionally: traditional concepts are alive and dynamic in Korea and must be recognized in Korean nursing.

Most of the tourist resort facilities in our country cannot be used in the winter season, and only a few spa resorts and sky resorts are available in the winter. To ameliorate this problem, various types of winter resort facilities have been constructed since 1970s and the massive development of winter resort facilities changed the resort market from a seller's market to a buyer's market. There has been however,few researches on marketing strategies for winter resorts, and there is a growing need for a rational method to maximize tourists' satisfaction and developers'profit at the same time. This research aims to develop a positining strategy to engance the marketability of winter resorts by classifying the resort market with the self-image types of users, and by analyzing the structure of the market, users' preferences, and locational factors. A survey was conducted with cases of Yong-Pyung resort, Mu-Ju resort, Alps resort, Bears resort, Back-Am spa resort, Su-An-Bo spa resort, and I-Chon spa resort. A list of questions in five categories -- similarity, characteristics, preferences, self-image, and personal characteristics of the respondents -- was constructed and tested. Among the 750 copies of questionnaire distributed, 700 were returned by only 378 were analyzed after screening missing or reckless answers. The statistical analysis of the data were conducted using techniques of correlation analysis, frequency analysis, factor analysis. Factor analysis and cluster analysis were used to group the cluster of self-image and a discriminant analysis were used to confirm this classification. The demographical characteristics were identified by frequency analysis, and resorts attributes were analyzed by oneway ANOVA analysis. Multidimensional scaling methods such as KYST, PROFIT, and PREFMAP were used for the positioning strategy.

Science curriculums for elementary schools were, traditionally, developed to be balanced in content and contain equal proportions of the four branches of science: physics, chemistry, biology, and earth science. To develop a successful science curriculum, we asked some questions about how elementary students recognize these branches and about what they think of the domains of science in the science curriculum. Our study was designed to investigate how elementary students classify the domains of science in the curriculum. Previous research (Lee et al., 2001) seemed not to be successful, because verbal expressions in that research might be inappropriate for elementary students who were unaccustomed to the technical language of science. For this reason, instead of using only words, we developed image card instruments, made of picture duplicates of the introductory covers of each unit in the 3$^{rd}$, 4$^{th}$, and 5$^{th}$ grades' science textbooks. We asked students to classify these cards into their own categories and record the reasons for classifying them. The ratio and distribution of the units was then analyzed to identify their view of the science domains. 30% of the 4$^{th}$ grade students created the following categories: 'nature,' 'observation,' 'seasons,' 'living things,' 'sounds,' 'separating,' and 'the things necessary for everyday life'. In the case of the 5$^{th}$ grade, over 30% created the categories of 'living things,' 'weight,' and 'water.' Over 30% of the 6$^{th}$ grade created the categories of 'nature,' 'light,' 'water,' 'living things,' 'solution,' 'fire,' 'properties of an object,' and 'experiment.' Upon scrutinizing the above results, we discovered that the science domains selected by students into three types of domains: academic contents and concepts; activities related to a science class; and lessons and experiences in students ' lives. The last category was a new, complex kind of domain. We concluded that students did not utilize the four branches of science when constructing their own domains of science. Instead, they created many alternative domains, which reflected students' thoughts of and their experiences. The educational needs of elementary students suggest that when organizing science curriculum as 25 % allocation of the four science branches, newly-created domains should be considered.

This study has purpose to perform leaving the hospital nursing plan during hospital treatment of patient with the knee ligament Injury on the basis of the concerns between the time of leaving the hospital after 2 weeks in hospital and the concerns through practical life after leaving the hospital systematically. This study is also tried to make exercise plan to prevent atrophy of Quardriceps muscle of the thigh caused by the limitation of activities. The subjects of study are 12 people who were in the hospital in affiliation to a university in Seoul, were operated on the knee ligament, and were discharged from the hospital within 2 weeks. Data collection time was for about 4 months from December, 94 to March, 95. Research method was performed 2 times by unorganized open questions. The collection of first data is through direct interview about the concerns before leaving the hospital, and secondary data is through direct interview about the concerns by practical life and experiences after leaving the hospital. The data was categorized by classifying several common elements among similar contents according to data by the situational analysis of Giorgi. The result of this study is as follows : 1) The concerns before leaving the hospital are like that the concerns of recovery possibility, the limitation of activities, the grim realities of life, the lack of confidence about self-nursing, the eyes of the surroundings, the burden to the others, and so on. 2) The concerns after leaving the hospital are like that the demands of the inconvenience by the limitation of self-nursing, the support about self-nursing by the difficulties of performing treatment order, the support of physical activities limitation by physical tiredness and the limitation of social activities, the support of information by the necessities of education in using crutches before leaving the hospital and continuing informational needs, psychological and mental support of normal physical recovery by the worries of physical recovery and physical change, and social support by thankfulness for his family and relatives. I suggest to make more systematic leaving the hospital nursing plan and exercise education plan for nursing plan after leaving the hospital of the patients with the knee ligament injury on the basis of this content.
