Multiplexed 수열을 이용한 선형복잡도

김선옥,최재승 한라대학교 2006 論文集 Vol.9 No.-

In this paper, we studied linear complexity, minimum polynomials, and a period of binary sequence that are created when multiple shift registers are combined using multiplexed sequence Due to security reasons, using a large-sized shift register has substantial difficulties Hence, to make up for the weakness of this kind of linear shift register, the stream password system must be nonlinear It is necessary to have more than two linear shift registers in a way to adapt nonlinearity, and it uses a multiplexer to combine the two linear shift registers

한국인 독일어 학습자의 어휘오류분석

Heute geh¨ort die Wortschatzarbeit zu den elementaren Aufgaben des Fremdsprachenunterrichts. Denn die Kenntnis und Beherrschung von W¨ortern und die F¨ahigkeit zur situationsangemessenen Anwendung des erlernten Vokabulars sind die Voraussetzungen zu fremdsprach- licher Kommunlkation generell. Aber erst in den letzten 15 Jahren hat man sich intensiv mit der Frage der Wortschatzarbeit und ihrer Wichtigkeit beim Fremdsprachenlernen auseinandergesetzt. Zwar hat man schon in den 70er und 80er Jahren die Wichtigkeit der Wortschatzarbeit erkannt, aber sie beschr¨ankte sich auf Lese- und H¨or¨ubungen. Erst in den 90er Jahren begann man mit der systematischen und gezielten Wortschatzarbeit im Fremdsprachen- unterricht. Wenn ein Lerner anfangt, eine Fremdsprache zu lernen, wird er in erster Linie mit fremden W¨ortern konfrontiert. Gerade in einem kommunikativen Unterricht lernt der Lerner anhand des vorgegebenen Wortes die Aussprache, die Bedeutung und die Anwendungsm¨oglichkeiten(Grammatik). Je l¨anger sich nun der Lerner mit der Fremdsprache besch¨aftigt, desto gr¨oβer wird die Schwierigkeit bei der Erschlieβung der Wortbedeutung, w¨ahrend der Schwierigkeitsgrad bei der Aussprache und der Grammatik abnimmt. Aber nicht nur die schwierige Bew¨altigung der Lexik verlangt eine Schl¨usselfunktion f¨ur die Wortschatzarbeit, sondern auch die Erkenntnis, dass der falsche Gebrauch der W¨orter einen direkten negativen Einfluss auf die Kommunikation aus¨ubt. Ein falsch gebrauchtes Wort kann, im Gegensatz zu einem Grammatik- oder Aussprachefehler (der von den meisten Muttersprachlern als Kommunikation nicht st¨oerend toleriert wird), eine ¨uberraschende, von der beabsichtigten abweichenden Reaktion beim H¨orer hervorrufen. In der vorliegenden Arbeit wurden Aufs¨atze von Lernern in den fortgeschrittenen Kursen am Goethe-Institut auf lexikalischer Ebene untersucht. Bei der Analyse der lexikalischen Fehler in den Aufs¨atzen wurden die vier Kriterien, deren sich Marilyn Martin bedient, herangezogen. Die Analyse l¨asst den Schluss zu, dass die Fehler auf lexikalischer Ebene einerseits auf interlinguale bzw. Interferenzfehler zur¨uckf¨uhren lasen. Andererseits entstehen die Fehler auch dadurch, dass die Bedeutungsschattierungen eines Wortes nicht voll erfasst werden. Im Rahmen der Arbeit konnte aus Platzgr¨unden nicht auf die Didaktik und Methodik der Wortschatzarbeit eingegangen werden. Die Verfasser werden aber dies bei einer anderen Gelegenheit nachholen.

The purpose of this study is to analyze the general component and food additives in sausage, ham, bacon and fish paste. The qualities of these products were compared based upon the Food Law of Korea. The results of the general component analysis were as follow: In sausages, the percentages of starch, phosphate, added moisture contend and fat content were very high, but those of protein content were low. The qualities of the pork-sausage were relatively better than those of the fish-meat mixed sausage. In hams, the percentage of fat, starch and added moisture content were low, whereas those of protein content were high. In fish paste, the percentages of the total and added moisture content were the highest and those of starch content were relatively high. But those of fat content were very low. The results of food additives analysis were as following: 1) Concentration of nitrite as the precursors of nitrosamine in hams was 14.7ppm/㎏, bacons 10.42ppm/㎏, sausages 1028ppm/㎏. Nitrite content of fish paste was of the least amount among them. 2) Concentration of nitrate in bacons was 220.2ppm/㎏, hams 206.7ppm/㎏ and fish paste 18.0ppm/㎏. Nitrate content of bacon was the highest amount. 3) Concentration of sorbic acid as the preservatives in bacons was 1.79g/㎏, hams 1.50g/㎏ and sausages 1.27g/㎏. 4) By the qualitative analysis of phosphate, the monophosphate was in hams, sausages and fish paste. The addition of up to 70ppm of nitrite in edible meat products, 50ppm of nitrite in fish products and 2g/㎏ of sorbic and in all products are permissible in the food hygienic Law of Korea. Food additives of all the products analyzed were within the limitation.

Preventive effect of dietary fiber to cardiovascular disease has been known for a long time. Recently, cardiovascular disease emerged as the leading cause of death in Korea. In this study. amount of dietary fiber intake and the effects of dietary fiber on serum lipid levels were investigated among cardiovascular patients. Seventy five out-patients with myocardial infarction(MI) history of more than 3 month past were selected and all subjects were gathered on July 7 for cardiac rehabilitation program. Twenty four hour recall was conducted to investigate amount of dietary fiver intake by trained interviewers. Serum lipid levels were determined on a fasting blood specimen obtained by venipuncture after an interview. Total triglyceride, total cholesterol and HDL-cholesterol levels were measure using automatic analyzer and LDL-cholesterol levels were calculated using the Friedewald's equation. The average dietary intake was 5.75/day which was about 34% of average dietary fiber intake level in rual Korea. The average age of the subjects in the present study were 63 and 66% of the subjects were more than 60 years old. Average caloric intake of the subjects were 1511.3㎉. protein intake was 58.2g Since most of the subjects were under nutitional status, the dietary fiber intake level was calculate as the amount per 1000㎉ caloric intake. The average was 3.84g/1000㎉. Total serum triglyceride level was 169.5㎎/㎗, total serum cholesterol level was 188.9㎎/㎗, serum HDL-cholesterol level was 42.1㎎/㎗ and LDL- cholesterol level was 113.0㎎/㎗ The amount of dietary fiber intake and the serum lipid levels did not show any significant correlation. This might be due to the low dietary fiber consumption. The overall food and nutrient consumption of the subjects was very low and modification of patients' poor eating patterns would play a key role to rehabilitate of MI patients.

The increase of CO2 in the atmosphere by fossil-fuel combustion has been recognized as a major cause of global warming. Thus many studies on CO2 removal from the combustion gas have been performed, and recently the techniques for biological CO2 fixation by photoautotrophs have also been developed, In this study, extensive screening was conducted to obtain micoorganism with high capability in fixing CO2, and its characteristics was investigated. As a result, a chemoautotrophs identified as a Aeromonas sp. strain JS-1 was isolated from the fresh water. The isolated strain used the molecular hydrogen and CO2 as an energy and a carbon source, respectively. Growth characteristics, which will be used in the development of a continuous culture system related in CO2 fixation, were examined in batch cultivation under conditions of various CO2 and NaCl concentrations, temperature, and pH. The results of the examination showed that the isolated strain had a good growth to high CO2 concentration(40%), indicating applicable in removing CO2 discharged from industries.

河床에 賦有되어 있는 모나자이트에 對하여 : Based on ChoongBuk Province Area 忠北을 中心으로

金相玉,趙璇衡 淸州敎育大學校 1977 論文集 Vol.14 No.-

The monazite deposits in south Korea are widely distributed as placer deposits, especially associate with gold placer deposits. The source rock of the monazite placer deposits in Korea are chiefly old aged granite gneiss, granite(chiefly schistose granite and two mica granite), mica schist and pogmatite. When these rocks which contain as much as 0.0018 percent of monazite were destroyed, the monazite bearing heavy sand were deposited mainly at the lower reaches of a river and at ragged beach(prevalently middle east cost) through sedimentation. We can assume that in Choong Bug Province the favorable environment for the monazite placer deposits lie in narrow river (less than 30m in width) and in auriferous strata above the bed rock, which are not far from the source rocks. No vein type deposits are found in Korea. Before 1958, the monazite were actively produced from many placer deposits, but during several years till 1966 a reduction in foreign market demand led to the repose of many monazite mines. Despite of the foreign market depression, from 1964 the domestic demand have increased and led to the production of several manufacturer, like a welding agent fire proof material and radiation. In Choongbuk Province, the Gamgok and Sangkeug area were covered granit gneiss, there are the ratio of Ilmenite 32.7-34.4%, Garnet 23.5-31.1%, Monazite 18.8-22.5%, Zircon 7.2-9.6% and Magnetite 59.6%, and there are included a few of accessory minerals such as epidote and ilomonite. The radio of granite area is as follow: limonite 59.6%, Magnetite 20.8%, Zilcon 8.2%, Monazite 5.6%, and Garnet 3.4%. At Jincheon and Mudbak area, there were covered with mica schist, granite gneiss and aluvium. The ratios of rock forming mineral are Garnet 34.5%, Zilcon 19.5%, Ilmenite 16.5% and Monazite 13.8%. In case of Youngduri area, there is Monazite 0.096% which contained chemical analysis of ThO₂ 5.9% and R₂O₃ 55.3%.
