This survey was accomplished to know the characteristics on the variation of water quality around Daechung-dam regulating reservoir. The algae bloom occurres near the chungju and Taejon intake station in autumn every year. It is possible to cause the taste and odor problems in the water supply if this reservoir will be a intake station. The comparsions of water quality data between within main dam and around regulating reservoir during past about 5 years were investigated. The water quality of this reservoir was the raw water supply II class, but its quality was the raw water phosphorus concentration as compared with past 5 years is increasing to be about two times. When the algae bloom occurred, dominant algae species was Aulacoseira glanulata having no correlation with taste and odor.

The purposes of this study were (1) to reexamine what were found by the survey on KNU Teachers College Students after the Pilot School Project (Ⅰ) in order to assess the possibility of .generalizing results of the survey across different groups of students who enter Teachers College after the Pilot School Project was implemented, (2) and to examine students' opinion toward the current procedures of assingning freshemen to departments or majors of the Teachers College. The subjects were freshmen of KNU Teachers' College from 1975 to 1777 academic year. However, the data pertaining to the students from 1975 to 1976 had been gathered while the survey on Teachers College Students after the Pilot School (Ⅰ) was being carried out. In order to collect the data with regard to the students entered the Teachers College in 1977, four different questionnaives were employed. The data were statistically tested by means of chi-technique only when it seemed necessary and appropriate. Major findings of this study are as following: (1) After the Pilot School Project was employed, there were general tendency in students' reason applying for admission to KNU Teachers College: Each academic year, approximately 40% of freshmen decided to enter the college to be secondary school teachers in the future. (2) Students' attitude toward the new procedures of screening college applicants, which was employed after the Pilot School Project, were negative in general. Furthermore, their negative attitude became stronger year by year. (3) The degree of students' satisfaction with their majors were relatively higher than that expressed by the students who entered the college before the Pilot School Project was employed. (4) Both students' criteria for selecting their majors and then reasons for changing their majors which they had been interested in applying were varied across time subjects and time. (5) The obtained contingency coefficient between departments and GPA students of each department earned during thir freshmen year was 0.831. It seems to indicate that majority of freshment tends to choose their majors according to their GPA rather than their interest or aptitude. (6) Approximately 67.73% of freshmen of the 1977 academic year accepted the end of the academic year as the most appropriate time for assigning them to departments they desire to enter. 7) Approximately 52.10% of freshment supported the idea of assigningas many students to the departments as they wish to enter, as far as it is possible, by adjusting the capacity of department, which is regulated by MOE. (8) Approximately 61.08% of freshmen claimed not to deduct their GPA when their first choice of department became impossible and turned down to the second or the third one.

Chitin has a hard crystalline structure originated from intermolecular force with aminoacetyl group. So it is insoluble in the general organic solvent and very limited to choose the proper organic solvents. Chitosan, deactylated product of chitin, is made by heating of chitin in conc. alkalline solution. It is, however, precipitated in neutral or alkalline region. It has been studied the water soluble chitin and chitosan for application in the fields of food, cosmetic, agriculture and medicine. In this paper, the applications and developments of watersoluble chitin and chitosan is introduced

Background:There are many global assessment scales for Alzheimer's disease. The clinical Dementia Rating Scale (CDR), the Global Deterioration scale (GDS) and the Blessed Dementia Rating scale have been widely used for evaluating the severity of dementia and might be useful for measuring the change of a patient's status. the CDR has been regarded as the golden standard for the severity of dementia. However, this interview-based scale takes up to 30 min for the clinician to complete, which is impractical in many clinical settings. Furthermore it is not so much sensitive for detecting the change of disease progression in each cognitive domain. We developed a brief and reliable questionnaire for evaluating the severity of dementia, called Cognitive-Clinical Dementia Rating Scale (CCDR). Methods:The CCDR consists of 15 questions that allow to assess the orientation to time, the orientation to place, the orientation to person, memory, attention, language, visuospatial function, frontal executive function, physical self maintenance, home and hobbies, community affair, the duration of dementia, mental alertness, walking ability, onset of abnormal behavior and character change. Ninety-eight probable and possible AD patients received the Clinical Dementia Rating Scale (CDR), Korean version of Mini-Mental State Examination (K-MMSE) and Cognitive-Clinical Dementia Rating Scale (CCDR). We tested validity and reliability. Results:The CCDR was significantly correlated with CDR (r=0.86, p<0.01) and K-MMSE (r=-0.88, p<0.01) and internal consistency was 0.96. Conclusion:The CCDR may be an easy and brief rating scale for the global assessment of Alzheimer's disease with excellent validity and reliability.

Background: Confrontational naming test is useful in evaluating the language function. It reveals memory and cognitive processing dysfunctions in many neurologic diseases including dementia. Although the Korean version of the Boston Naming Test (K-BNT) has been a popular and useful test, it takes much time and effort in dementia patients of moderate to severe stage of disease or in elderly individual with low educational level. So we developed the Korean Naming Test (KNT). Methods: KNT consists of relatively easy 40 items. Each item was familar materials around us and simplified figures with black thick line. Ninety two of probable Alzheimer's patients received the Korean version of Mini-Mental State Examination (K-MMSE), the Korean version of expanded Clinical Dementia Rating Scale (CDR), K-BNT and KNT. We tested reliability and validity of KNT and also evaluated scores of the KNT along with CDR. Results: The KNT correlated with K-BNT [0.75(p;0.01)], CDR [-0.49(p;0.01)], K-MMSE [0.55(p;0.01)]. The internal consistency was 0.91 (Cronbach's alpha). The KNT score decreased as the disease progressed. Conclusions: The KNT is a brief and good test for evaluating language function of moderate to severe dementia patients with low educational level. Also it is sensitive to mild stage of disease and has a excellent reliability and validity.

통신시스템 유지보수를 위한 최적 예비 회로팩 수량 결정에 관한 연구

이태훈,임건우,윤홍상 광주대학교 1997 産業技術硏究 Vol.8 No.-

교환 및 통신시스템을 운용할 때, 서비스 지속시간을 만족하면서 경제성 측면에서 최적 예비 회로팩의 수량을 산정하는 것은 중요한 문제가 된다. 본 연구에서는 각 회로팩에 대해 고장율과 실장 개수, 서비스 지속율 등에 따라 예비 회로팩 수량을 결정하는 모델을 제시하였고 프로그램을 위한 설계방안을 제시하고 있다. In an environment operating switching and transmission systems, it is a critical factor for the operation to decide the quantity of optimum reserved PBA (Printed Board Assembly) considering the economic factors while satisfying the service continuity time. The paper suggests a model which can decide the number of spare PBA's depending on the failure rate, the quantity of the installed elements, and the rate of service continuity for each PBA. It also delivers a design method for actual computer programming covering the subject.
