In the last few years, there has been a significant growth of interest in how the philosophy of science can be related to science education. Adequate understanding of the philosophy and history of science can promote understanding of the nature of science in teacher and student. The 6th curriculum in Korea has also placed emphasis upon understanding of the nature of science. From this point of view, to ensure effective school science education it is necessary to investigate how teachers and students are understanding the nature of science. To do this 45 secondary science teachers and 191 students of 7 schools in Seoul are administered Nott and Wellington's questionaire(1993). This questionaire is consisted of 24 Likert Scale statements and asks questions on 5 subscales of philosophy of science :Relativism-Positivism, Inductivism-Deductivism, Contextualism-Decontextualism, Instrumentalism-Realism, Thinking science education as a Process or a Content. The results of this study are as follows : 1. Teachers' view of the nature of science was relativism, deductivism, decontextualism and instrumentalism. And they thought process is more important than content in science education. 2. There was no difference in teachers' conceptions on the nature of science according to experience and gender. 3. Students' view of the nature of science was relativism, deductivism, decontextualism and instrumentalism. And they thought process is more important than content in science education. 4. There was no difference in students' conceptions on the nature of science according to schools level(middle vs high) and gender. But, female students exhibited higher score than male students on deductivism(p<.05). 5. Teachers' and students' conception of the nature of science was in agreement with each other.

Alberti's De re aedificatoria is the earliest case in the history of Italian Renaissance architectural treatises dealing with recovery of antiquity through textual and archaeological pursuits. The key source of the Renaissance theoreticians was Vitruvius' De architectura. However, Alberti was keenly aware of inaccuracy and Hellenization of Latinity in this classical text, and tried to compensate them in his own treatise. Furthermore he claimed a reformed discipline of the architects as well as the patrons, and prescribed how future buildings and cities should be built, based on the proper authority of ancient architecture in proper and intelligible Latin. Such an adaptation of classical usage in order to reestablish a modern norm preceded in his earlier work Momus, a satire on the contemporary Italian society of his own by following the model of Lucian. Alberti's suggestion of proper government in Momus's phrase was expanded in De re aedificatoria, for he consider the buildings are subject to the rules of morality and public interests. He proclaimed that the nature of beauty is the reasoned harmony of every part within a body, and architectural beauty also lies on the harmonized arrangement of all the elements within an individual building and of all individual buildings and facilities within a city. For the architects to execute this task, he formulated the concept of lineanenta, the form derived from the mind in order to prescribe the proper place, numbers, scale, and orders for whole building structure. It is the future oriented city-plans and building designs to serve the public interest and the good of all the individual citizens who make up the City-State that Alberti pursued in his treatise.

The Punggi (風旗) is one of the meteorological instruments made in the Joseon Dynasty (朝鮮王朝). Its purpose was to observe the direction of the wind. It is estimated that it started its operation in the $16^{th}$ century at least. But it does not remain in a perfect form, like the Chugugi (測雨器) and the Supyo (水標). The Punggi (風旗) can only be found at old document data, while the stone used to build the Punggi still remains. Since the stone had been named as the Punggi-dae (風旗臺) by 和田雄治 (1917), the name has not been changed until now. The Punggi is currently located in the Gyeongbok-gung (景福宮) and the Changgyeong-gung (昌慶宮). Meantime, there have been several transfers of its position. However, 和田雄治 (1917)'s paper and the "每日新報" (Maeil-Sinbo, 1929) articles have provided new clues. Also, the word 'Hupungso (候風所)' was found in the "朝鮮王朝實錄" (The annals of the Joseon Dynasty) and the "承政院日記" (Daily records of royal secretariat of Joseon dynasty). A designed harbor where the ship was staying was usually considered a special section for wind observations. It is assumed that the Hupungso was in most of the harbors at that time. This paper assumes the Punggi and the Hupungso had a lot of interest in wind observations in the Joseon Dynasty. In this study, we'll look for contained information about the Punggi and the viewpoints about wind during the Joseon Dynasty.

Objective: To identify epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma based on ¹⁸F-fluorodeoxyglucose (FDG) PET/CT radiomics and clinical features and to distinguish EGFR exon 19 deletion (19 del) and exon 21 L858R missense (21 L858R) mutations using FDG PET/CT radiomics. Materials and Methods: We retrospectively analyzed 179 patients with lung adenocarcinoma. They were randomly assigned to training (n = 125) and testing (n = 54) cohorts in a 7:3 ratio. A total of 2632 radiomics features were extracted from the tumor region of interest from the PET (1316) and CT (1316) images. Six PET/CT radiomics features that remained after the feature selection step were used to calculate the radiomics model score (rad-score). Subsequently, a combined clinical and radiomics model was constructed based on sex, smoking history, tumor diameter, and rad-score. The performance of the combined model in identifying EGFR mutations was assessed using a receiver operating characteristic (ROC) curve. Furthermore, in a subsample of 99 patients, a PET/CT radiomics model for distinguishing 19 del and 21 L858R EGFR mutational subtypes was established, and its performance was evaluated. Results: The area under the ROC curve (AUROC) and accuracy of the combined clinical and PET/CT radiomics models were 0.882 and 81.6%, respectively, in the training cohort and 0.837 and 74.1%, respectively, in the testing cohort. The AUROC and accuracy of the radiomics model for distinguishing between 19 del and 21 L858R EGFR mutational subtypes were 0.708 and 66.7%, respectively, in the training cohort and 0.652 and 56.7%, respectively, in the testing cohort. Conclusion: The combined clinical and PET/CT radiomics model could identify the EGFR mutational status in lung adenocarcinoma with moderate accuracy. However, distinguishing between EGFR 19 del and 21 L858R mutational subtypes was more challenging using PET/CT radiomics.

This study begins by establishing the theory that paintings serve as a visual documentation of a particular era and record the ideal fashions and customs about dress behavior through the costumes represented in them and examines the close relationship between fashion and art, focusing on the influence of art on fashion, as well as that of fashion on art, for both painters and fashion designers. To attain the goal of the study, the selected objects of study are written references and dresses represented in paintings produced in the 19th century. Painters who were the subject of documentation created or popularized new fashion styles before the concept of 'fashion designer' was introduced in history. In order to capture and represent the ideal beauty of certain period, painters understood the important role of fashion. Their work not only included the designing of costumes or accessories for the sitters, but also the spreading of new fashion styles by showing the sitters wearing them. Study of the mutual relationship between fashion and art grew more vigorous among many intellectuals in a variety of fields beginning in the 19th century. The standing of fashion was elevated and the concept of the 'fashion designer' was introduced and the interest in the themes of a specific style or the background of a trend increased during this time period. Many contemporary fashion designers created dresses inspired by the costumes represented in paintings. The result of this study which focuses on the relationships between fashion, artist, fashion designer and art is that connection between fashion and art is closely and firmly formed. For several hundred years, painters were the creators as well as promulgators of fashion and fashion designers, from the 19th century until today, have obtained their creative inspiration from art.

Environmental medicine has interest in the effect of natural environment on the human health. Nature is usually understoodas' sky(天)' and 'earth(地)' which implies the harmony of humankind and nature(天地相應). As can be shown above, environment concept is the basic in Korean Medicine which originate in "Huangdi's Internal Classic" as clear medical form. According to "Huangdi's Internal Classic" man ought to abide by the nurturing 'Tao(道)' which is the way of life. This can be explained as the principle of balance, specially of yin(陰) and yang(陽) as is represented by the transformation of the energies from the universe. Life through the four seasons is also referred in the classic upon when four different climates have some effect on people, and the regional effect on health is also written there. Under the strict modem view, the achievement of the classic in the field of environmental medicine may be treated as primitive, but it was induced through long-term observation, so that once was state-of-the-art result at that time. But to solve the intrinsic weak points in traditional environmental medicine and also to harmonize with modern science to contribute to national health, the way of modem research can be applied to traditional concept on environmental medicine. Natural scientific approach is to avoid superstition and incantation. Strict method approach is to enhance accuracy and reliance in clinical observation. Overall, predictability can help develop the effectiveness and efficiency of diagnosis, treatment, recurrence, and prevention in environmental disease with holy method of Korean Medicine.
