  • The laboratory astrophysics is a new emerging field of basic sciences, and has tremendous discovery potentials. The laboratory astrophysics investigates the basic physical phenomena in the astrophysical objects in controlled and reproducible manners, which has become possible only recently due to the newly-established intense photon and ion beam facilities worldwide. In this presentation, we will introduce several promising ideas for laboratory astrophysics programs that might be readily incorporated in the Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL). For example, precise spectroscopic measurements using Electron Beam Ion Trap (EBIT) and intense X-ray photons from the PAL-XFEL can be performed to explore the fundamental processes in high energy X-ray phenomena in the visible universe. Besides, in many violent astrophysical events, the energy density of matter becomes so high that the traditional plasma physics description becomes inapplicable. Generation of such high-energy density states can be also be achieved by using the intense photon beams available from the PAL-XFEL.

  • To educate students to adjust and lead their future society oriented on technologies and information communications, most of the countries in the world try to reform their traditional mathematics education. Contemporary Mathematics in Context (CMIC) developed by Core-Plus Mathematics Project in WMU has been developed in order to assist school districts in reforming their high schools mathematics programs in the United States, and $7^{th}$ Korean National Mathematics Curriculum was developed to guide reforming Korean mathematics program in 1997. In this presentation, by analyzing essential differences between the two curricula according to Korean Mathematics Curriculum, we may find some implications of CMIC for Korean mathematics education.

  • We present an overview of the Extensional Object Model (ExOM) and describe in detail the learning and classification components which integrate concepts from machine learning and object-oriented databases. The ExOM emphasizes flexibility in information acquisition, learning, and classification which are useful to support tasks such as diagnosis, planning, design, and database mining. As a vehicle to integrate machine learning and databases, the ExOM supports a broad range of learning and classification methods and integrates the learning and classification components with traditional database functions. To ensure the integrity of ExOM databases, a subsumption testing rule is developed that encompasses categories defined by type expressions as well as concept definitions generated by machine learning algorithms. A prototype of the learning and classification components of the ExOM is implemented in Smalltalk/V Windows.

  • The present investigation was under taken to study whether the tumor-associated macrophages (TAM) of Daltons lymphoma (DL), a spontaneous transplantable murine T cell lymphoma can be activated to tumoricidal state by crude thymus extract. Intraperitoneal administration of thymus extract to DL-bearing mice resulted in activation of TAM with an enhanced IL-1, TNF and antigen presenting ability. It was found that treatment with thymus extract could also enhance the phagocytic and cytotoxic activity of TAM. However, only a marginal increase in arginase activity was observed. Till date to the best of our knowledge the effect of crude thymus extract on the activation of tumor associated macrophages has not been investigated, this study provides a new piece of information in the area of thymus therapy.

  • Background: Bilateral Tessier number 3 clefts are extremely rare, and their surgical treatments have not been well established. Case presentation: The authors describe the case of a patient with a right Tessier number 3, 11 facial cleft with microphthalmia, a left Tessier number 3 facial cleft with anophthalmia, and cleft palate. We repaired simultaneously the bilateral soft tissue clefts by premaxillary repositioning, cleft lip repair, facial cleft repair by nasal lengthening, midfacial advancement, and an upper eyelid transposition flap with repositioning both the medial canthi. Postoperatively, the patient showed an esthetically acceptable face without unnatural scars. Conclusions: We achieved good results functionally and esthetically by midfacial advancement with facial muscle reposition instead of traditional interdigitating Z-plasties. The surgical modality of our anatomical repair and 3 months follow-up results are presented.

  • Korean Costume has long history and functional aesthetic value compared with the traditional costume of other contries. But nowadays korean Costume is becoming more and more distant from the people in the world wide current. To domiciliate and spread out the Practical Korean Costume which the goverment selected as CI symbol representing Korean culture in the trend of times. We investigated and analysed systemically the consciousness of customers and the details of design. This study consist of theoritical study and positive study. Theoritical study has the esthetic characteristic(structure characteristics formative characteristic and the characteristic of color) As the conciousness of people change in modern life which everything change in high speed the esthetic characteristics of Korean Costume have changed in structure.

  • Purpose: The aim of this study is to review and analyze the status on the obstetric and gynecologic RCTs with acupuncture. Methods: Searching were performed in $7{\sim}14$ July, 2008. Search term used was "acupuncture" only. And we classified all the searched articles as diseases and related health problems. Then we also classified OBGY diseases and analyzed the trends of those parts. Results: We could search 666 articles, RCTs with acupuncture. Of them, we found 88 OBGY articles about nausea and vomiting in pregnancy, labor and postpartum. OBGY surgery, hot flashes and climacteric, ART, Disease with Pregnancy women and menstruation, fetal breech presentation, and breast disease etc. Conclusion: To improve traditional Korean OBGY research, it is needed activation of RCT research, study of meta analysis, development of clinical practice guidelines, variation of research subject, and co-works with conventional medicine.

Between Orientalism and Ornamentalism: Colonial Perceptions of Southeast Asian Rulers: 1850-1914

  • Finding distinguishing characteristics of Southeast Asia has proven to be a significant challenge: by focusing on the encounters which primarily colonial British writers had with the region's state rulers, it becomes possible to recover the early conceptualizations of regional governance. The writings of Henry Yule, Anna Leonowens, Sir George Scott, and Hugh Clifford all document the "orientalist" features of Western discourses because these writers at once were affected by it as they contributed to it. The discourse about royalty and rulers was central to many of the tropes associated with orientalism, but also with 'ornamentalism'. David Cannadine has shown that ornamentalism (in which British conceptualized many imperial practices in relation to their own hierarchical conceptions of society) was as critical a feature of imperial outlook as was orientalism. The need to understand ruling elites was at the heart of the imperialist project. Tracing the ways in which colonizing powers represented the region's ruling elite offers a new avenue for recognizing the affinities of the regional experience. Beyond orientalism, the paper explores questions about the representation and presentation of authority. Understanding the conceptualizations of rulers is connected to the comprehension of social organization-including representations of "traditional society."
