Salivary research is at a critical crossroads regarding the clinical application of the basic knowledge. The purpose of this article is to introduce the current progress on salivary research to Korean dental scientists. The accumulated results based on advance technologies such as protein chemistry, molecular biology, and structural biology have showed that salivary macromolecules need structural requirements for proper function. Currently, several concepts or principles, which can be applied to salivary macromolecules, have been suggested. These include the role of molecules' conformation on biological activity, their multifunctional nature, their redundancy of function, their amphifunctional properties, and the potential importance of complexing between molecules. These concepts and the information available will help the development of saliva substitutes, the design of drug carriers and chimera molecules with enhanced function and the development of gene therapy protocols. These approaches will alleviate or restore lost salivary function and can be used to treat various kinds of oral and systemic diseases.

The concept of frame in semantics has implications for our understanding of such problematic terms as "meaning" and "concept". It is conventional to say that a particular word corresponds to a particular "concept" and to assume that concepts are essentially identical across speakers. In contrast, the notion of frame accepts that the frame for a particular word can vary across speakers as a function of their particular life experience. To say, instead of thinking in terms of words as expressing "concepts", we should think of them as tools, like frames, that cause listeners to activate certain areas of their knowledge base, with different areas activated to different degrees in different contexts of use. This notion is Fillmore's most crucial contribution to current cognitive linguistic theories, and his frame semantics is built on such a notion. This paper discusses the basic assumptions and goals of frame semantics, and examines the notion of frame and illustrates various framing words of English and Korean under such a notion.

The ultimate purpose of this study is as follows: The current primary concern in the defense sector revolves around how to strategically utilize Fourth Industrial Revolution technologies in combat. The Fourth Industrial Revolution denotes a shift towards an environment where automation and connectivity are maximized, driven by technologies such as artificial intelligence. Coined by Klaus Schwab in the 2015 Davos Forum, this term highlights the significant role of machine learning and artificial intelligence. Particularly, the military application of Fourth Industrial Revolution technologies is expected to be actively researched and implemented. Combat involves military actions between units, typically conducted as part of a larger war, with units striving to achieve one or more objectives. The concept of combat refers to the fundamental ideas of how units should engage with the enemy, both presently and in future scenarios, to achieve assigned objectives.

This study focuses on seeking a desirable direction for the discussions about identity issue of the current Traditional Korean Medicine(TKM). The identity issue of the current TKM is about asking what exactly the current TKM is, what sets the TKM apart from the other medical systems, and what value the TKM has in the contemporary settings, and seeking suitable answers to all these questions. The most important factor that affects these answers is what kind of the concept of identity we have. Current discussions of the identity issue of the TKM take narrow and inflexible concepts of identity such as "Numerical Identity," or "Qualitative Identity", not suitable for TKM, which is always changing and open to other academic fields. This study suggests that Hannah Arendt's concept of identity is more desirable for the TKM, which highlights pluralism and relations, as well as defining identity as a creative, positive, and open-ended process. In addition, this study also suggests that taking a closer look at the "field", which has previously been hidden behind the discourse on the "modernization", will help in figuring out what exactly the identity of the current TKM is. Lastly, the current discussions about "unification of Eastern and Western medical system", and "Integrative Medicine" in Korea will affect the identity issue of TKM.

We review here research and development progress achieved in US Plasma Chamber technology roughly over the last decade. In particular, we focus on two major programs carried out in the US: the APEX project (1998-2003) and the US ITER TBM activities (2003-present). The APEX project grew out of the US fusion program emphasis in the late 1990s on more fundamental science and innovation. APEX was commissioned to investigate novel technology concepts for achieving high power density and high temperature reactor coolants. In particular, the idea of liquid walls and the related research is described here, with some detailed examples of liquid metal and molten salt magnetohydrodynamic and free surface effects on flow control and heat transfer. The ongoing US ITER Test Blanket Module (TBM) program is also described, where the current first wall/blanket concepts being considered are the dual coolant lead lithium concept and the solid breeder helium cooled concepts, both using ferritic steel structures. The research described for these concepts includes both thermofluid MHD issues for the liquid metal coolant in the DCLL, and thermomechanical issues for ceramic breeder packed pebble beds in the solid breeder concept. Finally, future directions for ongoing research in these areas are described.

Objectives : The acupuncture has been in the classic arsenal of Oriental medicine over inflammatory diseases. Its physiological mechanism is not fully understood but being known better everyday. We reviewed several papers to describe current concepts over anti-inflammatory mechanism of acupuncture. Methods : Some computerized literature searches were done using the key words of 'acupuncture' AND 'Anti-inflammatory' in Medline via Pubmed between March 2007 and December 2007. Only rationally-designed studies were picked among practically associated materials. A well-known hypothesis on acupunctural physiology was adapted for integration. Result : 18 studies were selected. 17 studies were laboratory experiment and 1 was a clinical study. Data was classified into some comprehensive categories. Author's opinion was added at the end of each category. Study results supported the hypotheses on acupunctural physiology; Acupuncture has some influences on autonomic nerve system(ANS). And it stimulates several receptors from target cells like macrophage, and finally inhbits cytokines like TNF-${\alpha}$, IL-1${\beta}$ andIL-10 which are inflammation-mediated. Acupuncture increases the opioid releasing therefore relieves inflammation. And acupuncture inhibits cyclooxgenase(COX) but its mechanism is controversial until now. Conclusion : Current concepts over anti-inflammatory mechanism of acupuncture are as follows. Acupucture suppresses inflammation by stimulation of ANS, increasing of opioid releasing and inhibition of COX. But more studies are needed to fully describe the anti-inflammatory effect of acupuncture.

In order to apply SFCLs into electric power systems, the urgent issues to be settled are as follows, such as initial installation price, operation and maintenance cost due to ac loss of superconductor and the life of cryostat, and high voltage and high current problems. We designed novel hybrid SFCLs which combine superconductor and conventional electric equipments including a vacuum interrupter, an electro-magnetic contactor and a current limiting reactor. The main purpose of the hybrid SFCL is to drastically reduce total usage of superconductor by adopting current commutation method by use of the superconductor and the fast switch. According to protective coordination and performance, we investigated two concepts of Hybrid SFCLs. First is a half cycle fault current limitation type and second is a non-half cycle fault current limitation type. We concluded that the non-half cycle fault current limitation type is batter than the other.

The purpose of the study was to investigate middle school students' comprehension about analogies for explaining conceps related to electric current. For the study, 14 seventh grade students and 14 eighth grade students were sampled, and they were divided into two group, one group for implementing pictorial analogies, the other for analogies in words. The subjects are academically high achievers. The conclusion of this study is that the middle school students' comprehension about analogies of electric current is low. So the author of this study suggests that conditions as analog and context of analogy usage should be considered for the use of the analogies.
