This study was made to understand a hypoglycemic action of the fat soluble fraction of Panax ginseng C.A. Meyer in streptozotocin induced diabetic rats by determining the activities of several enzymes related to carbohydrate and lipid metabolism as well as several blood component levels such as glucose and ketone bodies, and non-esterified fatty acids. Albino rats (Sprague Dawley, 170-200g, 3) were injected once with 70mg streptozotocinhg body weight intraperitoneally and fed with ordinary diet for 7 days, and then the fat soluble fraction (5 mg~20 mg/day/rat) was injected intraperitoneally once a day for three days to rats having high blood glucose level over 340 mg/100ml. After a final injection of the fat soluble fraction, rats u.ere starved for 16 hours followed by the analysis of blood serum and liver enzymes. It was found that increased levels of glucose, ketone bodies and free fatty acids in streptozotocin induced rats were decreased appreciably by administration of the fat soluble fraction. However, the amount of administered fat soluble fraction did not show any significantly different hypoglycemic action. Decreased activities of glucokinase, phosphofructokinase, pyruvate kinase, 6-phosphogluconate dehydrogenase and acetyl CoA carboxylase of the liver of streptozotocin induced diabetic rats were greatly modified suggesting that a hypoglycemic action of the fat soluble fraction was also appreciable as ginseng saponin fraction. We also compared a hypoglycemic action of the fat soluble fraction prepared from American ginseng and Chinese ginseng with that of Korean pain ginseng. 핀o significant difference of the hypoglycemic activity was observed between the above ginseng fat soluble fractions, suggesting that a study of the fat soluble fraction might be one of the most interesting subjects relating to diabetic hyperglycemia in the near future.

The main objective of this study was to find participant's recognition about and meaning of stream trekking activities by analyzing their reports after visiting Gumgang, which was a kind of field experience combined with environmental education programs. In addition, this work suggested a few points that might help improve trekking programs, trail establishment and the overall field activities along the river. Eighty reports were collected from the participants who had joined in the Gumgang trekking programs organized by both Green Korea United in Daejeon and Gumgang Basin Environmental Office of Korean EPA. A database of texts in the reports was created for the preliminary analysis and then the results were further examined in a qualitative methodology. The results of qualitative analysis demonstrated that before experiencing the trekking activities in the Gumgang, many participants seemed uninterested in a river itself, objectified it, or simply recognized functional roles. It is found that most participants preferred crossing rapids to other activities. Crossing rapids has the eleven positive aspects as follows. First of all, crossing rapids is fun and scary experience at the same time. Secondly, it is painful, but makes people feel happy ironically. Third, rapids themselves make people reminisce about their childhood and feel freedom. Fourth, they make people feel comfortable. Fifth, crossing rapids is addictive. Sixth, rapids have life. Seventh, people can learn how to adapt to nature through the experience in them. Eighth, they can make people cooperate. Ninth, they can make people recollect their old friends. Tenth, people can extend their experience near rapids to rivers. Eleventh, they can make people reflect themselves. There ere three remarkable findings about experience in rapids. Crossing rapids was an activity that most participants preferred and could make the goal of trekking in the Gumgang effectively achievable. By crossing rapids participants can understand both lively and painful parts of the river. Participants think tour guide was an essential part to trekking along the Gumgang.

Die vorliegende Arbeit setzte sich zum Ziel, deutsche verbale Phraseolexeme(vPL) auf der Grundlage einer Mehrebenenbeschreibung syntaktisch sowie semantisch zu untersuchen. Dabei $st\"{u}tzten$ wir uns vor allem auf die Valenz- und Kasustheorie sowie das 6-Stufen-Modell von G. Helbig(1983) und das Mehrebenenmodell $f\"{u}r$ vPL von B. Wotjak(1992), das seinerseits vom methodischen Ansatz her in engem Zusammenhang zu dem Beschreibungsansatz steht. Aber Wir modifizierten teilweise das Modell yon B. Wotjak(1992) und stellten einige vPL exemplarisch dar. Dieser Untersuchung lag eine verbozentrische Auffassung des Satzes zugrunde: Das Verb bildet das organisierende Zentrum des Satzes und ist fur die Grundstruktur des Satzes verantwortlich. Das Verb als $Valenztr\"{a}ger\;er\"{o}ffnet$ um sich herum bestimmte Leerstellen, deren Zahl und Art letztlich von der Verbbedeutung her determiniert sind. Auch vPL kann als $Valenztr\"{a}ger$ - wie das Verb - das strukturelle Zentrum des Satzes darstellen, d.h. vPL bildet als Ganzes das $Pr\"{a}dikat$, das wendungsextern eine bestimmte Zahl von Leerstellen $er\"{o}ffnet$ und determiniert im Satz mit seinen $inh\"{a}renten$ semantischen Merkmalen seine semantische und syntaktische Umgebung. Bei der Analyse von vPL gingen wir von der Auffassung von B. Wotjak aus, $da\ss$ Modelle zur Beschreibung von Verben prinzipiell auch auf die Beschreibung von verbalen PL anwendbar sind. In dieser Untersuchung verwendeten wir - in Anlehnung an B. Wotjak(1996:4f.) - den Terminus 'Phraseologismus' als Oberbegriff, der a) Kollokationen, $b)\;Funktionsverbgef\"{u}ge\;(FVG)$, c) Wortidiome (wortwertige idiomatische Redewendungen oder Phraseolexeme), d) Satzidiome(satzwertige idiomatische Redewendungen bzw. kommunikative Formeln/ Routineformeln), e) $Sprichw\"{o}rter\;umfa{\ss}t$. Wir $beschr\"{a}nkten$ uns den Gegenstand unserer Untersuchung auf verbale Phraseolexeme(vPL), d.h. wie oben genannte Wortidiome. VPL lassen sich $prim\"{a}r$ in bezug auf das wendungsexterne ($\"{a}u{\ss}ere$) Aktantenpotential(PLe) und $sekund\"{a}r$ in bezug auf die interne Kom­ponentenstruktur des PL(PLi) klassifizieren. Unsere Studie soil nicht nur Hintergrundwissen $f\"{u}r$ Lexikonein­tragungen vertiefen helfen, sondern auch $f\"{u}r$ den Fremdsprachen­unterricht von Nutzen sein.

The chloride volatilization method for the recovery of zirconium and removal of uranium from zirconium containing metallic wastes formed in spent fuel reprocessing was studied using the simulated alloy waste, i.e. the mixture of Zr foil and UO$_2$/U$_3$O$_{8}$ powder. When the simulated waste was heated to react with chlorine gas at 350- l00$0^{\circ}C$, the zirconium metal changed to volatile ZrCl$_4$showing high volatility ratio (Vzr) of 99%. The amount of volatilized uranium increases at higher temperatures causing lowering of decontamination factor (DF) of uranium. This is thought to be caused by the chlorination of UO$_2$ with ZrCl$_4$vapor. The highest DF value of 12.5 was obtained when the reaction temperature was 35$0^{\circ}C$. Addition of 10 vol.% oxygen gas into chlorine gas was effective for suppressing the volatilization of uranium, while the volatilization ratio of zirconium was decreased to 68% with the addition of 20 vol.% oxygen. In the case of the mixture of Zr foil and U$_3$O$_{8}$, the V value of uranium showed minimum (44%) at 40$0^{\circ}C$ with chlorine gas giving the highest DF value 24.3. When the 10 vol.% oxygen was added to chlorine gas, the V value of zirconium decreased to 82% at $600^{\circ}C$, but almost all the uranium volatilized (Vu=99%), which may be caused by the formation of volatile uranium chlorides under oxidative atmosphere.ere.
