Using the full potential linearized augmented plane wave (FLAPW) method, the influences of uniform and tetragonal strains on the magnetic state have been explored for chemically ordered bulk $L1_2$ $FePt_3$. The ordered state displays antiferromagnetic $Q_1$ (AFM-$Q_1$) state but it transitions into antiferromagnetic $Q_2$ (AFM-$Q_2$) state at about 10% uniform strain. The ferromagnetic (FM) state is observed at 11% uniform strain. For tetragonal strain, it is also seen that the transition from AFM-$Q_1$ to AFM-$Q_2$ depends on the strength and direction of the applied strain. The FM state does not appear in this case. Magnetocrystalline anisotropy (MCA) calculations for tetragonal distortion reveal that the spin reorientation transition occurs. In addition, we find that the direction of magnetization and the magnitude of magnetic anisotropy energy strongly depend on the c/a ratio.

This research started from the premise that East Asia - China, Korea and Japan - played a remarkable role in the development of modern architecture. In this study, attention is paid to the lack of a synthetic research about the influence of East Asia on European modernism as a counterpart to its influence on American modernism. Thus, the intention of this paper is to construct an integrated discourse on the East Asian contribution to European modern architecture. By analyzing recently published/presented articles on the related subjects, this study suggests how European modernists encountered the East, what attracted them to the East, and how they applied East Asian aesthetics in their designs. While a number of architects adopted East Asian formal elements directly, at times superficially, others extracted the underlying principles. As a whole, this analysis offers insights at several levels. First, it provides a balance to the view of the East Asian influence on modern architecture by providing an investigation into its influence on European modernism as a counterpart to its influence on American modernism. Second, the multi-faceted nature of modern architecture is further illuminated in this study. Third, an important example of "positive-Orientalism" is provided, which contrasts with the rather negative image implied by E. Said's 'Orientalism'. In conclusion, this paper provides a critical assessment of the fundamental motive of European modernists' adoption of East Asian aesthetics.

The latest innovation in the field of fashion comes in the form of 3D-printed clothing. This study explores the composition and characteristics of the shapes in the architecture of Zaha Hadid, a representative architectural designer who expresses space in three dimensions. Hadid applies his aesthetic to fashion design using these distinctive geometric shapes to create design motifs as well as develop new clothing material with 3D printing technology. The research was conducted as follows. First, the lines and arrangement of the geometric shapes in Zaha Hadid's architecture were analyzed so that his design principles could be used as a theoretical basis for this study. The study also reviewed geometric fashion designs using 3D printing technology over the last ten years. Second, we developed triangular modules with rods and tongs that could be fashioned into clothing using fused deposition modeling (FDM) 3D printers. Lastly, the 3D printing fashion design was developed to explore new silhouettes, textures, and a novel way of producing clothing. This study hopes to serve as a stepping-stone for further research on innovations that combine fashion with technology.

The purpose of this study is to investigate what influences students' preferences on empirical and deductive proofs and find their relations. Although empirical and deductive proofs have been seen as a significant aspect of school mathematics, literatures have indicated that students tend to have a preference for empirical proof when they are convinced a mathematical statement. Several studies highlighted students'views about empirical and deductive proof. However, there are few attempts to find the relations of their views about these two proofs. The study was conducted to 47 students in 7~9 grades in the transition from empirical proof to deductive proof according to their mathematics curriculum. The data was collected on the written questionnaire asking students to choose one between empirical and deductive proofs in verifying that the sum of angles in any triangles is $180^{\circ}$. Further, they were asked to provide explanations for their preferences. Students' responses were coded and these codes were categorized to find the relations. As a result, students' responses could be categorized by 3 factors; accuracy of measurement, representative of triangles, and mathematics principles. First, the preferences on empirical proof were derived from considering the measurement as an accurate method, while conceiving the possibility of errors in measurement derived the preferences on deductive proof. Second, a number of students thought that verifying the statement for three different types of triangles -acute, right, obtuse triangles - in empirical proof was enough to convince the statement, while other students regarded these different types of triangles merely as partial examples of triangles and so they preferred deductive proof. Finally, students preferring empirical proof thought that using mathematical principles such as the properties of alternate or corresponding angles made proof more difficult to understand. Students preferring deductive proof, on the other hand, explained roles of these mathematical principles as verification, explanation, and application to other problems. The results indicated that students' preferences were due to their different perceptions of these common factors.

In western clothing, woman's body was port-rayed sexually as the distinction of sex was appeared, and the parts of body contain some kind of symbol of sex. Woman's body was diversly accentuated according to the divers ideal beauty concepts pursuits in the different periods. Today, in a Post-industrial Society whose social structure is very divers and complicated, the interpretation of woman's body reveals so various as the complex social structure. The purpose of this study is to comprehend the various interpretations of woman's body in the contemporary clothing. The concrete purposes of this study is as follows. First, this study is to define the concept of natural body and built body by differentiating the parts of body and searching for the sexual symbols accentuated in the western clothing. Second this study aims to review, the histori-cal process of prejudged distinction of sex in the western clothing, and to analyse the con-temporary sociocultural which forced to change this prejudged distinction of sex. Third, on the bases of this analses, this study also aims to present various interpretation on divers aspects of woman's body portrayed in the contemporary clothing. The interpretation of woman's body in the contemporary clothing were as follow. First, it is a body interpreted as a natural and neutral body which is based not so much on prejudged division of sex as on the expression of the body structure. And, it is a decomposed and recomposed body which is based on plastic principles. This body is portrayed by a layer-ing and wrapping which interrogated such traditional symbols of western clothing as collar, sleeve or trousers, skirt, etc. Second, it is a sexually symbolized body. This body is display-ed by exposure or sexual accentuation in the clothing. To conclude, a body interpreted in the contemporary clothing is no more a body accentuated by division of sex, but a body which per-mits indefinite hypotheses and interpretations under synthetic imagination.

This study is to describe the principles and outcome of the development for a classification scheme of presidential records to manage efficiently and provide them as archival information service productively. First, this scheme accommodates a management aspect, taking consideration into the aspect of archival records as the results of government administrative duties. Additionally, governance aspects are embraced into this scheme since presidential records can be seen as the results of governing purpose. We are considering the functional aspects of the public records too. As a result, this scheme adopts both management and governance aspect. Focusing on reflecting both functional and governance aspects, first analyzes existing classification systems in domestic and abroad. Finally, this study proposes 24 first-level, 114 second-level, and 179 third-level classification categories. Archivists and classification experts examined the classification scheme for verification by advisory meetings.

Lee Jae Won is a scholar who wrote the most in Euirim, a representative Oriental Medical magazine after the liberation of Korea, on the Sa-am Acupuncture Method. In order to understand the principles of this method, he proposed rather distinctive theories called the Comparative Pulse Diagnosis and the Five Constitutions. Lee Jae Won distinguished the deficiency and exuberance of the Five Phases through the Comparative Pulse Diagnosis, and set harmonizing the Five Phases by tonifying the deficient and purging the exuberant as the object of the Sa-am Acupuncture Method. He took pulses from both the patient's hands and distinguished the deficiency and exuberance of the five viscera. Then, he balanced the Five Phases by tonifying the weakest viscus and purging the strongest viscus. Lee Jae Won argued that because the Five Constitutions are something that one has innately, people suffer from differnet diseases according to their constitutions. Therefore, he argued, when treating a patient, one should first decide the constitution of the patient and then treat the patient according to his/her deficiency or exuberance. From the late 50's to early 60's, Lee Jae Won wrote Acupuncture and Moxibustion According to Yin-Yang and the Five Phases, explaining the principles of the Sa-am Acupuncture Method and its applications. Seen from this, Lee Jae Won is a person from whom we can confirm the historical lineage of the Sa-am Acupuncture Method after the liberation of Korea.

Objectives : The purpose of this study is 1) to explore the general tendency of the herbs or herbal formula for acne treatment in clinical practice 2) and to provide a basis for explaining the principles of acne treatment in Korean Medicine in order to make patients understand more easily based on pharmacological mechanism by analyzing the herbs or herbal formula using for acne treatment in clinical practice. Methods : In the domestic databases (Oriental medicine Advanced Searching Integrated System-OASIS, Korean Traditional Knowledge Portal-KTKP, National Discovery for Science Leader-NDSL, Research Information Sharing Service-RISS), we selected among the papers published using search terms related to "acne". Reports related to sasang constitutional medicine were excluded and a total of 23 papers were finally selected. Results : 29 prescriptions were retrieved from 23 papers. Chungan-tang (淸顔湯) notified formulas ranked first by Cheongsangbangpung- tang (淸上防風湯), Hwangnyeonhaedok-tang (黃連解毒湯), Dangguijakyaksan (當歸芍藥散) and Bipachungpe-eum (枇杷淸肺飮). Commonly used herbs are Forsythiae Fructus (連翹), Scutellariae Radix (黃芩), Gardeniae Fructus (梔子), Ligustici Rhizoma (川芎), and Angelicae Gigantis Radix (當歸). In most patients with inflammatory lesions or excessive flushing, exterior-releasing medicinal (解表藥) and heat-clearing medicinal (淸熱藥) were mainly prescribed for acne treatment, while in patients with acne accompanied hyperkeratinization, Excess sebum secretion, Dysmenorrhea or indigestion, qi-tonifying medicinal (補氣藥) or blood-tonifying medicinal (補血藥) were mainly used. KAGS (Korean Acne Grading System) was the most commonly used method for acne severity assessment. Conclusions : These findings suggest that the herbs or herbal formula for acne treatment in Korean Medicine is prescribed differently according to the cause and symptoms of acne in a unique way for control the whole body balance. Also, our findings could provide a basis for explaining the principles of acne treatment in Korean Medicine in order to make patients understand more easily based on pharmacological mechanism in clinical practice.

It is quite true that the more Korean contractors receive overseas contracts, the more they need guarantees. The top market for them is the Middle East countries, consisting of more than the half of the total amount awarded last year and the trend is increasing as well. The problem, however, is that employers in these countries are reluctant to use international rules for guarantee such as URDG or ISP98 and easily make unfair callings. However, Korean contractors(applicants), especially small and medium sized enterprises(SMEs) tend to hurriedly enter a contract without looking into its contents as well as guarantees. They do not realize the importance of the guarantees until they receive callings from the employers(beneficiaries). Being independent from the underlying contracts, guarantee is the equivalent to cash in that it usually does not require any proof of demand when calling and the guarantor should make a payment within usually 5 business days after the request. It is often observed these days that several Korean SMEs go bankrupt due to liquidity risks after receiving unfair callings from employers in the Middle East countries. In retrospect, some cases could be obviated if contractors were a little more careful in checking the contents of a guarantee at the time of concluding a contract. For example, there is one case where the underlying contract includes a reduction clause in the Advance Payment bond and the guarantee does not have that clause. In the end, the Korean contractor had to take the whole burden of the bond amount though it had finished 81% of the project. Nobody could argue that contractors should take a full responsibility if they fail in their obligations. However, the employer's wrongful callings need to be prevented in the first place, if possible. As there shouldn't be a case where one party is at a disadvantage against the other like the case mentioned above, useful insight is being sought to minimize unfair calling risks for the benefit of the applicant. First, the applicant should carefully look into every detail of the potential guarantee before signing a contract, heeding especially that there is a reduction clause in the AP bond. Second, the governing principles for guarantee should be the ones that are internally used such as URDG758 that is objective in terms of callings given that, for example, it specifies that the requirement for a supporting statement when making a demand is a default rule. It is also recommended that the form of guarantees be the standard demand guarantee. Third, parties involved in issuing guarantees are advised to understand international rules for guarantee like URDG758 and ISP98 and to play a key role in guiding SME contractors in Korea so that they can protect themselves from possible wrongful callings, particularly from employers in the Middle East countries. I hope this study would give a wake-up call for Korean SMEs wishing to do business in the Middle East countries and remind them of the importance of guarantee itself and its governing principles.

The purpose of this study is to discuss the main principles and concepts of social constructivism, examine the literature on the application of social constructivism in medical education, and explore the meaning and limitations of the utilization of social constructivism with learning theory. A literature search was carried out in two stages, utilizing PubMed, CINAHL and Education Source databases. The first search included both fields (social constructivism AND medical education), while the second search was performed by subject (Vygotsky or ZPD or zone of proximal development or scaffolding AND medical education). A total of 96 papers were found through the first and second searches, and after reviewing the abstracts of all 96 papers, 41 papers were deemed suitable for research purposes. In medical education, social constructivism is applied in areas such as (1) social and cultural behaviors (hidden curriculum), (2) social construct of "meaning" (dialogue and discourse), (3) learner's identity transformation (expert), and (4) instructional intervention (ZPD and scaffolding). Social constructivism has provided many ideas to explore in terms of the composition of knowledge in the sociocultural context of health care, but it has not demonstrated an explicit instructional method or educational effects.
