The purpose of the study was to identify the living pattern and the space use in Urban Houses, Seoul, Chunju, Ulsan were selected as study sites. The space organizing form and space use was investigated by means of interviews. Through various ways of analysis, we could find that the function of Anbang, Guesil, Buauk were multipurpose. Anbang was not only for sleeping but also for entertaining and family living. Guesil(living room) is slowly gearing into family and entertainment rooms. Buauk are changing to the dining room as well as kitchen.

yongdam multipurpose is under construction to divert a part fo Geum riverlfow to Mankyung watershed and to supply the domestic water to the Chunju region and produce the hydro-electricity. Generally construction of dam by the method of inther-region water transfer affects the quantity and quality of water inthe down streams and reservoirs. The impact of operation plan of Yondgam dam on the quantity and quality of water in the Guem river and Daechung dam was investigated .It was recommended that the discharge of water transfer from one watershed to another should be minimized as much as possible.

KWON, Oh Yong (Chunju Teacher's Coll.) Partern of the amino acids influedced on nitrogen metabolism of edible bamboo sprouts. Kor. Jour. Bot. VI (4) : 5-10, 1963. It had been scarcely reported by any worker that the essential amino acids to be indispensable in our daily life contained in edible bamboo sprouts and that they had various pattern of free amino acids. For this reason, especially two species of Korean bamboo sprouts collected from the surburb of Chunju, in April, 1963 were used for researching the essential amino acids and free amino acids appeared on paper chromatography. The most suitable part for our edibles was investigated as a part of bio-chemical studies on Korean bamboo sprouts. The free amino acids contained in two species were found as 5-15 kinds and there were a few of difference according to it's growing parts. Many kinds of free amino acids were found in the end parts more than the tip parts and mid parts of bamboo sprouts. Besides, the essential amino acids in each species were found to 3-9 kinds. From the characteristics and the experiments marked above, it was suggested to the author that many kinds of free amino acids in the end part accelerated the formation of nitrogen comounds more than the other parts.

This study of children's perceptions own and desirable mothers was based on data gathered from answers to questionnaires by 46 preschoolers living in Chunju. The children listened to the stories of 3 picture books based on the interactionist, maturationist, and behaviorist theories of child development. Parenting behaviors were rated by standards of support and control dimensions. The subjects perceived their own mothers' developmental beliefs in rank order of maturationist, behaviorist and interactionist. Most parenting behaviors were perceived to be punishment. The subjects ranked the developmental beliefs of the most desirable mothers in order of maturationist, interactionist, and behaviorist. The most desirable parenting behaviors were perceived to be affectionate expression, recognition, and cooperation. There was no relationship between own and mothers' developmental belief.

During the period of June 15, 1978 to February 28, 1979 fungi were isolated from 101 public and home telephones in 6 different cities and classified. Total 203 isolates were obtained and classified into 8 genera and 6 species, however 44 of the isolates were unidentified. Penicillium spp. were frequently found. Forty isolates were derivated from coffee shops, 51 from street public telephones, 35 from stores, 26 from offices and 19 from homes. Also 27 were from Seoul, 30 from Daegu, 46 from Gunsan, 82 from Chunju and 18 from Jaeju. Twenty-seven were isolated in summer and 174 in winter. From the above observations, it is concluded that the transimitters are heavily colonized with various species of fungi and some of them are pathogens. The rates of colonization appeared to be various by locations and seasons.

Survey of the infection rate of Dirofilaria immitis in Korean dogs was made in Chunju area by means of Kume's Aectone-Concentrating method. During the period of 60 days(July August) 1cc of the blood was collected from Vena mediana antebrachii of each of 205 dogs over the age of one year regardless of its sex.(In this case 2cc syringe was used.) Time for collecting the blood was from 2 p.m. to 6 p.m. The collected blood was checked, using Kume's acetone-concentrating method.: The results were summarized as followings. Microfilaria was detected in 47 dogs(23%) out of 205. Based on the dog's age, microfilaria possitive rate is 15.5% (12 dogs out of 77) at one age; 24%(14 dogs out of 59) at the age of two; 28%(12 dogs out of 43) at the age of three; 5%(5 dogs out of 15) at the age of four.

The electronic ballasts for low pressure discharge lamps are produced and commercialized. However, the electronic ballasts for high pressure lamps are now in progress because of poor reliability and high cost. The major case of troubles with electronic ballasts are thermal destruction of semiconductor output switches due to non ideal i-v characteristics of switch. The loss converts to heat and rises the temperature of switch and it increases proportionally to switching frequency and value of current and voltage. This study shows the variable frequency ballasts which can suppress the heating of switches efficiently. It is used for the limitation the switch current and the rising temperature of switch by impedance variation of lamp inductor. As a result, initial warm-up time of the proposed ballasts was faster than that of magnetic ballasts about 90 msec. Power factor of tested ballasts follow as ; input and output average of magnetic ballasts are 93 [%] and 86 [%], respectively, And proposed ballasts are 97 [%] and 99 [%], respectively.

A theoretical and experimental study of a single link flexible arm a tip mass is presented for the translational end-point positioning. The problem of shifting the end-point from its initial position to the commanded position by the amount of W $_{d}$ is considered for the open loop control such that the base follows up the given path function. The theoretical results are obtained by applying the method of the Laplace transform to the governing equation, and the solution is calculated by the method of numerical inversion. Experimental results are obtained and compared with the theoretical ones.s.
