Sam Shepard is one of the leading American playwrights who represented Off-Off Broadway in the l960s and 1970s. In his early days, he wrote many experimental plays but later he turned to realism. However, under the superficial realism in his later plays, we find that they contain experimental devices and themes. True West (1980) is the last play of ills realistic family trilogy. This play shows that the tradition of Old West, which is symbolized and replaced by desert, disappeared in the industrialized clues of modern West. The Old West is compared which the modern West through the struggle of two brothers, Lee and Austin. Their father, 'Old Man', ran out on his family and went to the desert but did not succeed there. He shows that he failed in achieving the American Dream. The family appears unusual and demolished The relationships of the characters are not based on love and belief. The family symbolizes the negative aspects of modern American society. After Austin recognizes the actual situation finding that there is no real life in the modern West, he tries to leave the city and his family. He wants to go to the desert in search of a new life. However, in the last tableau Lee blocks the exit and the two brothers square off. It implies that they are doomed to continue their struggle. The message Implies that American society today is lacking the same positive values they once had in the Old West.

This study attempts to compare the topic "approximate value" in mathematics text-books of the 2nd year of South Korean junior high schools and that of the 3rd year of North Korean high schools. In addition, a survey questionnaire was distributed to junior and senior high school students as well as to mathematics teachers in South Korea. Based on the results of the survey, this study attempts to uncover the issues within the current teaching methods of "approximate value" and proposes the directions in which the teaching of approximate value should go in order to enhance mathematical thinking power and creativity of the students. First, it Is necessary to teach students how an error applies to the real world. To accomplish this end, it may be worthwhile to consider introducing the relative errors with more seriousness. Second, it is more important to teach the way of thinking which is concealed in the background of the calculation methods of approximate values than to simply teach mere calculation methods. Third, it is necessary to teach the calculation of approximate value with more realistic examples. Fourth, It is needed to teach students what the differences are when the terminology of "approximately" and "about" is used in real life and in mathematics.

The development of Science and Technology and the social change require new paradigm in Education. In a traditional paradigm, learners have been regarded as a passive being and knowledge could be transmitted to learner. But within this paradigm, it is difficult to confront the social change and to develop problem solving skills in various context. This results in a new, alternative perspective, Constructive paradigm. As an alternative to the traditional settings, Constructive paradigm emphasizes the learner centered instruction. The reform movement in mathematics education including NCTM's standards revolves around this paradigm and the open education movement in our educational system is based on it. Open education values learner's interest, autonomy and internal motivation in learning. However, open education has been misunderstood by most of the teachers. It should be understood as the change of paradigm. In this study, as a way of helping students connect mathematics to their everyday lives and construct meaningful mathematical knowledge and concept, mathematical modelling is suggested. It consists of posing and specifying the real problem, formulation and constructing a mathematical model, analyzing and solving a mathematical problem. interpreting the solution and comparing with reality and communicating results. In this process, technology like computer can be a powerful tool. It can help students explore various problems more easily and concretely.

The purpose of this study is to develop and apply a make-a-thon program based on engineering problem solving for science high school students and to analyze the changes of participating students. Through the consultation of teachers and experts, a team-based and student-driven engineering problem-solving-oriented make-a-thon program was developed. And, the program operated using KAIST's human and material resources for 51 students. Students composed of 12 teams studied 12 topics through an engineering problem-solving process, and the overall program satisfaction was very high, on average 4.62. Through this program, students' creative leader competency have been positively changed, especially in cognitive characteristics (diffusion thinking, problem solving ability) and social characteristics (pursuit of social values). Attitudes toward engineering also changed positively, especially in terms of difficulty of engineering, interest in engineering, gender role in engineering, and engineering and occupational factors. In conclusion, it was confirmed that this program is very effective for science high school students with high demand for engineering education.

This study examined the relationship between calling, organizational commitment, and innovation behavior among 302 current teachers. The main results are as follows. First, calling had a positive effect on the organizational commitment. Second, calling did not significantly affect innovation behavior. Third, Organizational commitment had a statistically significant positive effect on innovation behavior. The result of the study suggests that in order to enhance the teacher's innovation behavior, it is necessary to clarify the calling of the teacher's own work and make him/her feel so that it can lead to the desire and willingness to actively realize the organization's goals and values.

The purpose of the current study is to investigate parents' understanding and needs for character education in early childhood and during elementary education and to suggest policy implications effective character education for young children. Using focus group interviews, we collected qualitative data from 14 mothers in Seoul, Korea. The mothers were unclear about the definition of character education for their children and about their role in teaching proper values during the early years of their children's development. Most mothers with preschoolers were satisfied with the character education their children were receiving, whereas mothers with children in elementary school were not satisfied with the character education provided by school. The mothers expressed their concerns about the reliability of the teachers and schools of their children. As policy implications, providing regular parent education, activating parent-teacher associations, and strengthening the partnership through support from the community are suggested.

The purpose of this study was to investigate foodservice management of snacks as will as to evaluate nutrient intakes of young children from the snacks serried in early childhood educational institute. Two hundred and twenty-three snack items from 14 kindergartens and daycare centers were measured sewing size and analyzed for the nutritional values in addition to the general evaluation of the snack service management practice by the trained personnel. The results were as follow: The contents of most nutrients supplied from the snacks amounted to 10-15% of RDA (recommended dietary allowances for Koreans) except iron and niacin. And there were not any significant differences in the contents of energy, protein, fat and carbohydrate between the morning and afternoon snacks. The energy and protein contents (as the % of RDA) of snacks sewed to children of 1-3 years old were turned out to be significantly higher than that sewed to the children of 4-6 years old since the portion amount of snacks per child was about the same regardless of the age and individual variation. There were significant differences in the contents of nutrient serried from the snacks among 14 kindergartens. Therefore, nutritional guidence including the standard portion amount for the kindergarten snacks considering the age, activities and individual variation should be developed for kindergarten teachers so that they can effectively manage snack service and provide good nutrition for young children.

In the computer-aided detection (CAD) system of pulmonary nodules, a high false positive rate is common because the density and the computed tomography (CT) values of the vessel and the nodule in the CT images are similar, which affects the detection accuracy of pulmonary nodules. In this paper, a method of automatic detection of pulmonary nodules based on multi-scale enhancement filters and 3D shape features is proposed. The method uses an iterative threshold and a region growing algorithm to segment lung parenchyma. Two types of multi-scale enhancement filters are constructed to enhance the images of nodules and blood vessels in 3D lung images, and most of the blood vessel images in the nodular images are removed to obtain a suspected nodule image. An 18 neighborhood region growing algorithm is then used to extract the lung nodules. A new pulmonary nodules feature descriptor is proposed, and the features of the suspected nodules are extracted. A support vector machine (SVM) classifier is used to classify the pulmonary nodules. The experimental results show that our method can effectively detect pulmonary nodules and reduce false positive rates, and the feature descriptor proposed in this paper is valid which can be used to distinguish between nodules and blood vessels.
