微生物에 의한 n-alkanes의 資化와 乳化

마상조,김동필,조덕봉,최옥범 광주보건대학 1996 論文集 Vol.21 No.-

A long-chain n-alkane-using microorganism was isolated from a soil sample, and was identified to belong to genus Acinetobactor. This strain Ma-1 grew on n-alkanes ranging in carbon length from C_(13) to C_(44) as a sole carbon source. This strain could grow on the solid hydrocarbons without addition of any detergents. The growth and the hydrocarbon use were enhanced by the addition of a surface active agent, Plysurf A210G. A strain Ma-I culture isolated in our laboratory has been shown to produce an extracellular biopolymer with emulsifying properties when grown on a mixture of linear hydrocarbons. The substrates supporting good growth gave good polymer production. The polymers recovered from the substrates were found to be complex molecules or mixtures with a protein, a lipid, and a carbohydrate moiety.

As a result of research on the present condition of the department relating to food at the junior college as of 1987 in our country, the number of the departments are 23 cases and the full-time professors are 132 persons and the number of students are 3,760 persons. This study can see that our country has attached importance to food science education as fourfold in the number of students comparing with that of 1971. The character of the curriculum is different according to its systems, but it has the subject that need to train the major technicians and graduating students advance into each field. Because of great many of students who are trained in a field of food science, it can be said that further the food industry and the development of food science have good prospects. Food science is recognized as important thing to everyone due to a serious problem of food in accordance with the population growth and gradual scientific propulsion of the national dietary life. With the basis of the analytical about the curriculum of the department relating to the food of university and junior college in internal and external and the result that is analyzed students and teachers' replies by the questionaire, this study makes out a model plan of te curriculum in junior college like table 14. Though the curriculum is ideal and perfective, as if it is not governed well nothing can be obtained, the other way also even though the curriculum is not perfect, if the mystery of management is praciced, a good results can be getting. Especially modern creative way of field practice makes students themselves set up purpose to learn and look for its meaning, and as experimenting and confirming their own thought and ability through solution of problem it helps to get developed and made up theirs own self. Therefore constitution of course of the field pratice is established centering around the experence of students to set studying purpose. It is continuously managed to do the ideal studying by change of a time and demand of society, and also should be recognized to build up ability that judge and decide as theorizing a lot of knowledge on the conceptional and theorical basis. In the way that the department of food processing at a junior college should improve, improvement of educational equipment is urgent, then the cost of equipment should be secured and the curriculum should be improved. Finally, thank for every junior college who cooperate with this study and such study for more better fixed curriculum will be continued after this report. So there will be sufficient results.

AMC/TDM/CDM 다중접속방식에서의 Best Effort 순방향 서비스를 위한 Water-filling Based 채널 스케줄러

마동철,기영민,김동구 한국항행학회 2003 韓國航行學會論文誌 Vol.7 No.1

제한된 무선 채널을 여러 사용자들에게 공정성과 수율을 보장하면서 서비스하고자 제안된 무선 자원 관리 기법이 채널 스케쥴러이다. 비례 공정 스케쥴링 알고리즘은 AMC (Adaptivct Modulation and Coding)/TDM시스템에서 사용되고 있는 채널 스케쥴러로서, 이 알고리즘은 사용자들의 시간적인 공정성을 고려한 상황에서 수율을 높인 것이다. 본 논문에서는 CDM방식이 결합된 AMS/TDM/CDM 시스템에서 사용 가능한 채널 스케쥴러를 제안하였다. CDM 방식을 사용하기 때문에 TDM만을 사용하는 시스템에서처럼 매 시간 슬롯에 한 사용자만을 서비스하는 것이 아니라, 다중 코드 채널을 사용하여 여러 사용자들을 서비스할 수 있다. 따라서 매 순간 다중 채널의 사용자들에게 제한된 송신 전력을 할당하는 문제가 발생한다. 이것을 해결하기 위해서 본 논문에서는 water-filling 알고리즘은 water-filling스케쥴링 알고리즘에 사용자들의 평균 신호 대 간섭 전력비를 고려하여 사용자간의 공정성을 부여한 알고리즘이다. 본 논문에서는 레일레이 페이딩과 음영 및 경로 손실을 고려한 시스템 레벨 모의 실험을 통해 WF2 스케쥴링 알고리즘의 성능을 분석하였다. The channel scheduler is suggested the radio resource management method in order to provide service with guaranteeing fairness and throughput to the users who use limited wireless channel. Proportional fairness scheduling algorithm is the channel scheduler used in the AMC(Adaptive Modulation and Coding)/TDM system, and this algorithm increases the throughput considering the user's time fairness. In this paper is suggested the channel scheduler combining CDM scheme available in AMC/TDM/CDM system. Unlike the system which only uses TDM which provide the only one user at the same slot, this scheduler can service a lot of users since this uses the CDM scheme with multi-cord channel. At every moment, allocation of transmission power to multi-channel users is problematic because of CDM scheme. In this paper, we propose a water-filling scheduling algorithm to solve the problem. Water-filling fairness(WF2) scheduling algorithm watches the average channel environment. So, this modified method guarantees fairness for each user in terms of power and service time.

This studies were conducted to investigate the effects of rain shelter and netting on the tree growth, fruit set fruit quality of kiwifruit (Actinidia deliciosa). In rain shelter and net house, shoot falling wasn't occurred by strong wind, and fruit set, fruit weight and also fruit malformation, side flowering increased at the same time. In rain shelter house the increment temperature forced blooming date and increased shoot length, leaf number and diameter but in net house these tendencies were not observed. Relative light intensity of rain shelter house was higher than that of net house with standard of field culture (relative light intensity: 100%). Soluble solid content was higher in rain shelter house, and acid content was higher in net house. With the effect of rain sheltering the occurrence of bacterial bloom rot and canker significantly decreased in both rain shelter and net house but insect injury increased. These data showed that rain shelter house is more suitable for kiwi fruit culture.

In order to remove impurities which are pyrite particles mainly contained in pottery stone, mineralogical characteristics, particle size, pH, flotation time and the effection of collector amounts was examined. The raw minerals were analyzed by microscopy and X-ray diffraction, and the products of the flotation were analyzed by atomic absorption spectroscopy. The results obtained from these experiments are as follows; 1. Pottery stone mainly consists of quartz, montmorillonite, and pyrite. 2. Liberation effect was increased in smaller than large particle size because of ratio of surface area increasing. Suitable condition of seperated particle size was 60×100mesh. 3. The depressing effect of pottery stone was increased in acid region, but flotation effect of pyrite was much in effect at pH7. 4. Flotation rate of pyrite was over 97% at 5 min., and flotation rate was not changed over 5min.. Thus, the optimum flotation time was less than 5 min.. 5. The 96.15 percents of pyrite could be recovered with yield of pottery stone of about 90 percents by using 200g/t of KAX. Therefore, the optimum concentration of collector was appeared to be about 200g/t.

사이버 공간의 공동체와 분화 : 대학생PC통신 사용자를 중심으로

Community has been an important topic for social scientists, especially in regards to the processes of modernization and urbanization. Recently, in the context of the so-called "information revolution." on-line communities have gartered increasing interest. Despite wide and casual usage of the term "on-line community" in mass-media, little work has been done to conceptualize on-line communites and how they mimic and/or diverge from their more conventional (off-line) counterparts. This study hopes to fill this intellectual gap by re-examining the concept of community in the existing literature and by interpreting primary data collected through a survey of on-line interaction among college students. The existing literature indicates that communities in the 'real world' are not as spatially bound and homogeneous as the ideal-typical notion implies. Furthermore, our primary data shows that space and homogeneity even less significant for on-line communities, where interaction and subjective definition by participants are primary in community formation. Spatial locations(such as rural and urban)and off-line variables(such as gender or income)are not significant in the formation and types of on-line communities. This leads us to cautiously predict that on-line interaction may help construct a civil society based on solidarity other than traditional networks(such as school and regional ties).
