질소원으로서 계분을 이용하는 균주를 선별하고 계분배지에서 균체의 생육속도가 다른 균주에 비하여 우수한 균주를 분리하였다. 형태·생리학적 특성을 기초로 하여 yeast의 분류 기준과 비교하여 본 균주를 Candida sp.로 동정하였으며 본 균주를 Candida sp. D116으로 명명하였다. Poultry feces extract medium에서 4% 농도의 glucose 첨가가 균체 생육에 효과적이었다. D116 균주를 액체 발효하여 균체생산능, 요산 그리고 가용성 단백질의 변화를 조사하였다. 그 결과 약 60시간이 경과하면 액체 발효 배지내의 거의 모든 가용성 단백질 및 요산의 감소를 보였으며 균체생육은 약 36시간 배양하였을 때 최고조에 도달하였고 그 후에는 점차 감소하는 경향을 보였다. SCP의 대량생산의 결과 50%의 계분혼합 배지와 30℃의 배양 온도에서 36시간 배양하여 균주의 생육수준이 3.8×10^9 CFU/ml 농도의 균체를 생산하였고 200 L의 배양액중 약 870 g-dw의 균체를 얻었으며 생산된 군체의 조단백질 함량은 67%이었다.

流通情報化時代에 대응한 마아케팅情報시스템의 構築에 관한 硏究

宋均錫 건국대학교 1989 論文集 Vol.28 No.1

Information is one of the most powerful weapons in business. Companies rove to know what products their competitors are developing. But today, information is more than knowledge of what other companies are doing. An increasing number of firms are using the documents their companies deal with on a day-to-day basis as strategic weapons in the battle to hold customers and gain new market share. They're accomplishing those goals by using electronic data interchange. Today, information technology must be conceived of broadly to encompass the information that businesses create and use as well as a wide specturm of increasingly convergent and linked technologies that process the information. Most of enterprises have had a great effort to increase sales through competitions in buyer's market. The POS system, SA, VAN, CATV and so on are phenomena of distribution revolution. Especially, the introduction of POS system has soft merits and hand merits. However, the question how we can make the most of these merits depends on how we practically could harmonize the method with measures. The iformation revolution is affecting competition in three vital ways. ① It changes industry structure and, in so doing, alters the rule of competition. ② It creates competitive advantage by giving companies new ways to outperform their riyals. ③ It spawns whole new businesses, often from within a company's existing operation. In any company, information technology has a powerful effect on competitive advantage in either cost or differentiation. A marketing information system is a continuing and interacting structure of people, equipment, and procedures to gather, sort, analyze, and distribute pertinent, timely, and accurate information for use by marketing decision makers to improve their marketing planning, · implementation, and control. Following are the steps to take to design a marketing information system ; ① collect data from the various sources, ② computer the data from these sources into meaningful categories. ③ develop statistical and computers capabilities to analyze the data. ④ develop models capable of forecasting sales and predicting consumer and environmental change. ⑤ prepare ongoing repots in areas requiring continuous information. ⑥ prepare special reports for nonrecurring tasks. ⑦ make sure use right information is transmitted to the right decision centers within the organization. Well-run companies take additional steps to improve the quality and quantity of marketing intelligence. First, they train and motivate the sales force to spot and report new developments. Second, the company motivates distributors, retailers, and other middlemen to pass along important intelligence. Third, the company purchases information from outside suppliers. Fourth, some companies have established an internal marketing information center to collect and circulate marketing intelligence. In conclusion, information systems are a means to an end-decision making which leads to more profitable results. The concepts and developments for strategic infrmation systems discussed in this article are designed to help organizations make more profitable strategic decision.

效率的인 마아케팅 戰略樹立을 위한 家族購買意思決定에 관한 理論的 硏究

宋均錫 건국대학교 1988 論文集 Vol.27 No.1

The family is the basic purchasing and consuming unit and is therefore of great importance to marketing managers of most products. Families are also the primary mechanism whereby cultural and social values and behavior patterns are passed on to the next generation, thus performing the child socialization (unction. In view of this point, this thesis reviewed the buying decision making in family for marketing strategy and extracted some propositions from many existing studios as follows. ① Joint participation in decision making is more likely as the importance of the purchase increases. ② Decision making is more likely to be either joint or autonomic when the relative positions of the husband and wife are approximately egual. And decision making is more likely to by husband dominant when his states on these variables is higher than his wife's. Decision Making is more likely to be wife dominant when her status on these variables is higher than her husband's. ③ When children have only information from an advertisement about a product, their decision - making time will be greater than when they can combine advertisement information with information about how their parents regard the product. ④ When an advertisement is highly attrative, children will choose their preferred product regardless of their parents' strategy. ⑤ When an advertisement is moderately attractive, children will follow the surgestions if their parents use a reasoning strategy, but will react against their parents' suggestions if their parents use a power - assertive strategy. And while much remains to be learned about family decision making, I can offer five general conclusions. ① Different family members may be involved at different stages of the decision process. ② Different family members may evaluate different attributes of a product or brand. ③ The direct involvement of family members in each stage of the decision process represents only a small part of the picture. The taking Into account of the desires of other family members is also important. ④ Who participates at each stage of decision process and the method by which conflict are resolved are primarily a function of the product category and secondarily a function of the characteristics of individual family members and the characteristics of family. The product category is important because it is closely related to who uses the product. ⑤ Overt conflicts in decision mating are less common than agreement. Conflicts are frequently resolved through problem solving From the above conclusions, we can establish marketing strategy efficiently in content of advertising messages, media, product development, pricing, distribution.

스무 편의 사랑의 시와 한 편의 절망의 노래 : 무정부주의자의 사랑 An Anarchist's Love

우석균 이베로아메리카연구소 부산외국어대학교 2003 이베로아메리카 Vol.5 No.-

Este arti′culo intenta ubicar 20 poemas de amor y una oancio′n desesperada de Pablo Neruda en el contexto socio-cultural de los an­os 20 del siglo XX en que fue escrita; sobre todo centra su atencio′n en el "Poema 1" que se destaca por su erotismo. El erotismo de Neruda no es una actitud escapista como sen­alan varios cri′ticos literarios. Para Neruda, es un intento de ser contempora′neo con los artistas europeos. Por lo tanto, la opinio′n compartida entre muchos cnticos de que este poemario es arti′sticamente un retraso no es aceptable. Por otro lado, este articulo se interesa por el hecho de que el erotismo del "Poema 1" muestra una especie del instinto de destruccih. Este instinto procedi′o de la experiencia de la modernidad perifkrica de Neruda; concretamente, de una expenencia de la pobreza y de la falta de oportmidades. A partir de esta expenencia, Neruda senti′a una necesidad de romper el status quo de la sociedad chilena. El anarquismo de aquel entonces fue un arma para e′l; el amor destructivo tambie′n se debe a aqukl. Como el anarquismo, el amor de Neruda rechaza todas las instituciones de la sociedad.

서균석 安東大學 1984 安東大學 論文集 Vol.6 No.1

We take much interest in the education and training in business firms by gradually acknowledging more of the importance of the human resource development nowadays. In accordance with a timely demand, this is: 1. to discuss the close relation of the importance of the human resource development and the education, training in business firms. 2. to survey the theoretical background of the education and training in them. 3. to analyze our present situation. 4. to suggest the direction of improvement of it after looking for the problems. From now on, our enterprises have to change the formal, short-term and imitative attitudes on the education and training in them. Korean enterprises are immediately required to develop the education and training programs appropriate to them. Consequently, Top management should try to put the education and training programs on the business strategic level, and human resources for the enterprises. They have to take the education and training programs appropriate to the new business environment and the critical mind. At the same time, they need to improve the productivity through developing and bringing up the ability of the human resources.

The flow characteristics of impinging jet flow are affected greatly by nozzle plate to distances. An sharp edge nozzle was used to achieve uniform mean velocity at the nozzle inlet, and its diameter is 10mm(d). Therefore, the flow characteristics on the impinging jet plate can be changed largely by the control of main flow. In the parent study, we investigate the effects of main flow velocity, its variable is nozzle inlet velocity(1.5m/sec, 3m/sec, 5m/sec)

The definition of traditional 2-DS power factor current and co-ordinate did not represent clearly relation to power facter in circuit with nonlinear thyristor loads. A new simulator for performance evaluation of Active Power Filter (APF) by 3-D space current co-ordinate applicale to general power system have not been developed, because reserchers were merely interested in improvement of source current waveforms by using APF or its simulator. Moreover, There was not APF simulator with power analysis capability which was developed for the better. Current was decomposed by active, reactive, distortion, by digital correlation signal proccessing techique based on Nowomiejski theory. Therefore, A new 3-D space current co-ordinate composited by 3 current components was defined in this paper. A new 3-D space current co-ordinate was shown state and location of current vector by trajectories with 3-D co-ordinate rotation. It evidently has excellent performance not only performsance evaluation method of APF but alse evaluation method of general power system, not conventional domain but other domain. By proposed 3-D soace co-ordinate, space power factor is derived, the true state of physical meaning is proved, new distortion factor was proposed, this study was proved true state of appropriation throughout development of simulator for APF performance evaluation with power analysis capability.

대한제국기 민족지에 나타난 경제개혁론

최경숙 釜山 外國語 大學校 1995 外大論叢 Vol.13 No.1

From many publications in the Daehan Empire age we find leading editorials for the salvation of the country. In the editorials they longed for sovereign independence, and enlightened democratic rights and development of edueation. As we examine the policies and the economic reform arguments of The Independence, The Hwangseong, and The Daehanmail Newspapers, we see how they recognized and would have reformed the political, scial, and economic contradictions. The results from this study are as follows. First, the ethnographical newspapers (ENP) in the Daehan Empire age tried to find cause of underdeveloped industry in Korea in the feudal system. Second, as a specific device for development in industry the ENP suggested the establishment of capitalistic companies. Third, as the main cause of impeding the development in commerce and industry the ENP indicated that feudalism's way of thinking layed stress on ostentation rather than on substance. Fourth, though the ENP indicated the problems in feudalism's way of thinking, they did not fully recognize the weaknesses in feudalism's economic system. Fifth, as the cause of peasants' poverity, the ENP especially failed to notice the feudal landowner and land plundering system. Insteed they poverty was the result of the peasants' ignorance. Sixth, the ENP emphasized the sublation of feual value system on the one hand, but did not concern itself with changeing the feudal economic system on the other hand. Seventh, the ENP desired the capitalistic system, but did not recognize the contradiction between national capitalism and imperialism. Instead they encouraged wrongly imperialist invasion to develope the country in some aspects.
