  • The military vehicles are necessary to perform various war battle missions but in reality they are not as convenient as the civil vehicles. Thus, it is problematic regarding the satisfaction about convenience, operation, and performances of military vehicles. Since most of military vehicles used in Korea were made by bench-marking the models of United States developed in the latter half of 1970's. It is question whether the current military vehicles can provide the functions and expected performance fully or not if we do not study what the user friendly military vehicles are. This article report soldiers' user satisfaction survey on military vehicles and provide arguments on the priority decision based on users' requirements. Future direction for the development of military vehicles is discussed.

  • Recently it has become a common belief that ascorbic acid comes to break up in the process of making its color after peeling it. In this study the writer has attempted to observe whethier ascorbc acid really breaks up or not, what percentage of salt is needed in water to keep ascorbic acid in the best condition. Ascorbic acid was quantified by the spectrophotometric method. The results were obtained as follows; It seems that ascorbic acid does not break up considerably in mixing by the imxer for two minutes and if the mixing lasts longer ascorbic acid breaks up by heat and presumably by enzyme and oxidation. Generally at our home the breaking of ascorbic acid usually does not appear so much as only two minutes, mixing gives us the desirable result.

  • This research explores the intension of repeatable guests through on the wedding facilities, employees' service ability, and banquet menu. First, wedding facilities include transportation, parking lots, subsidiary facilities, reception desks, Paebaek Rooms, and waiting rooms for brides. Secondly, according to the analysis for service quality of hotel wedding feasts, respondence and sympathy were not be fully considered while good effects showed through materiality, reliability and conviction. Thirdly, hotels will be expected to have re-visiting guests when the guests have good experience on the hotel facilities and satisfying menu. Alternatively, menu would have a negative result if there's not satisfying service. Employees should be aware of the list of menu and can be able to offer a suggestion. In other words, a banquet has to be prepared not only with fresh or seasoned ingredients but with good service to make the guests revisit. Therefore, we should be aware of what our guests want and how to prepare for their satisfaction.

  • There are many position fixing systems in the world from ancient times. But the principles are to compare the position to want to know with the known position already. The position finding system which is not restricted by weather condition and/or electronic apparatus has been sought. The best system is the GPS as far. But the system has the fatal faults as follows; 1. to depend on satellite's accuracy, 2. not to use underwater. This paper is to investigate theoretically position fixing and north finding by using free gyroscope. This paper introduce a position fixing and north finding method by measuring inclination of 2 free gyroscopes. And this system does not depend on the weather condition and underwater condition. What is more, it could use on the planets, if the gravity exits.

  • This study aims to select eight books to see if "potential complement" is sufficiently acquired and properly used in Chinese conversation textbooks, explore the reasons and problems of learners' errors through analysis, and briefly suggest textbook compilation and teaching. Twelve criteria were established and analyzed, including the concept and format of "potential complement", layout order, location of objects, three types of forms, distinction from auxiliary verb "能" and distinction between "能+V+結果補語". Some of the results of the study are simply as follows. All eight textbooks focus only on "possibility," missing an important part of "the impact of objective conditions" that the term "potential complement" does not contain. This is certainly enough to cause confusion for learners. A poor understanding of the concept of "potential complement" results in identifying it with the possible auxiliary verb "能", and incorrect mixing because it does not know exactly what the difference is. Most of the textbooks compiled in China place a high importance on "potential complement". This means that Chinese people often use "potential complement" in real life. on the other hand relatively Korean textbooks do not deal with "potential complement" relatively importantly.

  • The 1990s have seen the publication of many books devoted to Language and Ideology (cf. Joseph & Taylor 1990. for one of the early ones) even though the term 'ideology' itself has remained ill-defined (Woolard 1998). The focus of attention has usually been placed on the particular use of language and often for some kind of 'political' ends, not on linguistic or other scholarship which might have been driven by some sort of ideology, i.e., a bundle of assumptions which themselves were taken as given. At least since Edward Said's 1978 book Orientalism, it has been clear to everyone that scholars construct their conceptualization of things in line with their understanding of the cultural, social, and political world in which they live, and that this often unreflected 'pre-understanding' effects their view of cultures that are different from theirs and more often than not geographically and temporally distant from theirs. This recognition has had a sobering effect no doubt, and Said's book has long since become 'mainstream.' Much more disturbing to the scholarly profession has been the publication of Martin Bernal's Black Athena in 1987, since it went much further, going beyond accusations of colonialism and cultural bias, in suggesting that the Western representation of Classical Greece over the past two hundred years was false and that what had been accepted until now about occidental antiquity must now be seen derived from African-Asiatic cultures of the Near East, notably that of the Ancient Egyptians, and that no other than Socrates should be seen as black man. While we may understand the intellectual climate in the United States that led academics to present 'myth as history' (Lefkowitz 1996), it is obvious that lines of regular scholarly principles of investigation have been crossed (cf Lefkowitz & Rogers 1996). The present paper investigates what may be seen as the ideological underpinnings of such work. After reviewing some recent scholarship in the area of linguistic historiography that have shown that academic work has never been 'value-neutral' (as may have been assumed or has been claimed by some practitioners), it is argued that in effect one must be aware of what Clemens Knobloch has recently termed Resonanzbedarf, i.e., the desire, whether conscious or not, of scholars-and probably scientists, too-to have their work recognized by the educated public and that, in so doing, their discourses tend to pick up on contemporary popular notions. These efforts may be harmless if everyone was to recognize these allusions and adoption of certain lexical. items(buzz words) as props or what Germans call Versatzstiicke, but history tells us that this has not always been the case. Still, as Hutton (1999) has shown, not all scholarship during the Third Reich for example can simply be dismissed as worthless because it was conducted in under a prevailing political ideology. Indeed, in seemingly innocent times, linguists can be shown to frame their argument in a way that makes them appear so utterly superior to their predecessors (cf. Lawson 2001). Upon closer inspection, those discourses turn out to be much like those of scholars in nationalistic environments that have tended to select their 'facts' to prove a particular hypothesis (cf., e.g., Koerner 2001). The article argues for scholars to take a more active role in exploding myths, scientifically unfounded claims, and ideologically driven distortions, especially those that are socially and politically harmful.

  • 1. Objectives There are many studies on the ordinary symptoms based on Sasang constitution. But there. are not quite satisfactory between the types of Sasang constitution. So This study is for learning the characteristics of ordinary symptoms depending on Soyangin Soeumin and Taeyangin Taeumin of the Sasang constitution. 2. Methods One thousand and two hundred twenty nine subjects were included in Bundang Oriental Hospital of Dongguk University. We classified them into the each type of Sasang Constitutional Medicine(SCM) by the well-trained SCM specialist, and assessed their ordinary features by the questionnaire. Binary logistic regression analysis was applied to evaluate the influence of ordinary features to the diagnosis of SCM. 3. Results (1) Compared to Taeyangin Taeumin, Soyangin Soeumin do not sweat a lot. Even if Soyangin Soeumifl do sweat, one does not feel refreshed. Soyangin Soeumin do not sweat while sleeping at night nor eating meals, but discharges cold sweat if one does not feel well. (2) Compared to Taeyangin Taeumin, Soyangin Soeumin go to stool less frequently and have diarrhea when one does not feel well. Soyangin Soeumin do not feel irritated even though one is not able to go to stool for one day. (3) Compared to Taeyangin Taeumin, Soyangin Soeumin do not have foams in urine. (4) Compared to Taeyangin Taeumin, Soyangin Soeumin tend to eat slow, do not eat a lot normally, do not have a great appetite, have problems for digestion, and especially have difficulties in digestion when one is stressed. 4. Conclusions We found that Taeyangin Taeumin and Soyangin Soeumin have characteristics of ordinary symptoms, but partly there are not in accoradance with ones what Lee ]e-Ma said in his book. So in future we hope clinical studies are required steadily.

The Real Nature of "Chomskyan Revolution" ("촘스키혁명"의 실상)

  • Quite a few historiographers of language science have measured the applicability of the term 'revolution' toward the line of work initiated by Chomsky, with the conclusion to the positive or negative effect as the case may be. This paper starts out with a brief review of this issue, with an interim conclusion that, while Chomskyan linguistics may be regarded as revolutionary in certain aspects, terms like 'revolution' and 'paradigm' are hardly applicable here in the way they were originally intended by Thomas Kuhn. It can be said, nontechnically, that the model of theory under discussion is at once 'revolutionary' and 'evolutionary' - in the sense that revolutions in linguistics have not resulted in abrupt loss of continuity with past 'paradigms', if there were any such. Chomsky's theory of language plays the same role of consolidation and refinement of structuralism that, say, the neogrmmarians played in their day. It has continued some fundamental traits of its predecessor, recovered others, and unwittingly rediscovered still others. But this is not the main thrust of the present paper. For, even if Chomskyan theory were to be looked upon as straightforwardly 'revolutionary', that revolution has not been a felicitous one. Some critic (Pieter A. M. Seuren, to be specific) goes as far as to say that "largely as a result of Chomsky's actions, linguistics is now sociologically in a very unhealthy state $\cdots$ to the point even of threatening to make that whole school of linguistics intellectually irrelevant." Besides, under the present state of language science that strikes one as typical of what Kuhn has characterized as "pre-paradigmatic" insecurity and disharmony, an unhealthy situation might take place if we were to think of the theoretical disagreements as conflicts between 'incommensurable' viewpoints-between 'rival paradigms' as it were-thereby avoiding or evading rational discussion. Another danger concerns the bandwagon effect, with linguists prematurely boarding each novel theory seemingly destined for popularity, for fear of being left clinging to an outdated 'paradigm.' Here lies another reason why the notion of 'revolution', Kuhnian or not, might as well be put aside, in the historiography of linguistics at the least.

In Search of an Efficient Market Mechanism for a Digital Economy: Virtual Field Experiments on Posted-price Markets and Auctions (디지털 경제에서의 효율적 시장 메커니즘에 대한 연구: 가격부착 시장과 경매에 대한 가상 실험)

  • In recent years, many retail businesses jumped on the Internet auction bandwagon and paid substantially high fees to learn and develop proper business strategies for this new environment. Unlike what most businesses in the real world presume, this research shows that discriminatory-price ascending-bid auctions in a digital economy might be not very beneficial for the sellers on the Internet, if sellers sell the identical digital products through both a typical posted-price market and an auction. Using an extensive technology infrastructure along with suitable incentives and rules for market agents, we found that a discriminatory-price ascending-bid auction, which is the most popular auction mechanism on the Internet, serves consumers better than it does the sellers or producers in the digital economy. That is, the average prices for digital goods in these auctions are substantially lower than the prices in a posted-price market. This shows that it is not so wise for sellers to jump on the bandwagon of Internet auctions, if there is a market place with posted-price mechanisms which sells comparable items, or if a seller does not have special advantages or strategies in this new market institution. Electronic market mechanisms provide powerful means of understanding and measuring consumer characteristics including willingness-to-pay and other demographics for sellers or producers. Many concern that sellers may extract the entire surplus from the market by using customization on the Internet, thus consumers will be worse off in this digital economy. We found that these sellers who can customize their products and prices fail to capture the whole consumers surplus and cannot exercise a monopoly. One major explanation for this phenomenon is that the competition among the sellers prohibits them from charging prices according to customers demand for each product, where switching from one seller to another is not so difficult for the customers, and reselling products among the buyers are prohibited.

  • Many teachers at vocational high schools have had difficulties overcoming the gap between what students know and what students have to achieve in many topics. Mathematics is toughest of all, since most of textbooks in electronics are assuming student's basic knowledge in math. Considering that many students with very low achievements are entering vocational high schools, reality is far from such assumption. Inevitably, we have to face two difficult questions; do we have enough time to teach these kids all the math that they need in two years? If not, what alternatives we should adopt? We just do not have enough time and therefore find out a way to cope with harsh reality. According to our preliminary study, we suggest that multimedia-based CAI may be the best way to attack this problem. From hardware point of view, fortunately, many of vocational high schools are reasonably equipped for multimedia-based education. However there have been hardly any effort to develop courseware for vocational education in Korea. In this paper, a CAI title for learning basic characteristics of alternating current has been designed and implemented. The developed multimedia-based CAI title has been applied with respect to first grade students at local vocational high schools. A survey after classes shows that CAI could help student feel much comfortable with Basic Electricity course and grasp physical understanding much easily. Accordingly we conclude that classes adopting CAI would be of great help to put education in vocational high schools on the right track.
