최근까지의 관습적인 예측으로보면 인간의 동력사용은 앞으로 수십년에 걸쳐 현재와 같은 비율로 지수함수적으로 증가할 것이며 이로 인해 당연히 전세계의 한정된 화석연료자원이 급속히 고갈되지 않을까 하는 우려가 제기된다. 그러므로 인간의 실수요에 대해 타당한 예측을 하는것이 우선적 문제인데, 이것은 세계인구수와 1년 1인당의 예상수요의 산출로 분류할 수 있다. 인구수에 관해서는 다음과 같은 낙관적인 견해가 있다. 즉 인구는 2,000년까지 현재의 비율(년간 2%)로 계속 증가하여 현 3.5*$10^{9}$에서 6.6*$10^{9}$ 이 될 것이나, 21세기중에는 일정한 수에 머무를 것이다. 동력의 1인당 실수요 평가에 있어서는 여러가지 요인을 고려해야 한다.

In order to investigate reproductive capacity of genus Lespedeza 5 spp,; L. bicolor, L. maximowiczii, L. japonica var. intermedia, L. angustifolioides, and L, cyrtobotrya, their hights, diameter at the ground level, and the number of sprouts were compared with each other at the end of October during investigating years from 1970 to 1972. For measuring of invested items, 6 stocks which the one-year aged stem were cut above ground were randomly planted per square meter with six replications at the spring of 1970. After hights, diameter, and the number of sprouts were measured at the end of October every year, the stem were cut above ground at the end of November from 1970 to 1972. The results are as follows: 1. The reproductive of the stems showed statistically significant differences at 1% level by species and stock ages. L. bicolor showed the best reproductive capacity of them. 2. The sprouting ability was revealed that L. maximowiczii showed the best of them. 3. The reproductive capacity of stem, diameter, and number of sprouts increased with aging of stock up to 4 years on the investigated 5 species.

Since 1972, Remote Sensing has been consistently developed and reached today's technology of gaining high resolution images from space, Images from some high resolution satellites have a spatial resolution better than 1m, for example, one by Space Imaging EOSAT which will be in operation by 1998. These Images can be used in various applicable areas such as map makings, surveyings, water resource management, agriculture, by many different users, for example, central and local governments, utility companies of gas, electricity, telecommunication, and so on. Specially, availability of 1m space images will bring revolutionary changes in map making methods that has been mostly adapted for air photos, In this paper, we review trends of this new technology and discuss how to use these images.

The present research is to study a variation of skirt length in the time series, from 1955 to 1986. The results are summarized as follows; 1. The most important event is the acceptance of Mini skirts during this period. This phenomenon will play an important role in later skirt length. 2. The year of the shortest skirt length is 1972, while the year of the longest skirt length is 1983. 3. Based upon the year of the shortest skirt length, the periods of the same skirt length are as follows; 1956-1975. 1964-1978. 1959, 1960-1980, 1981. 1961-1982. This phenomenon is irregularly appeared in this study, but shows the change of recurring skirt length. 4. The skirt length has been changed slowly and continuously during the long period of time. In particular, to reach the shortest skirt length takes longer time than that of the longest skirt length. 5. It has taken 6-8 years to reach the top period of Mini skirts (1971-1973) since shorts are introduced. Comparing this phenomenon in Korea with that in Japan, the time difference is about two years. 6. The periods of various skirts length are the year of 1970-1971 and the year of 1972-1973; This result is assumed that individual persons accept sooner or later the changed skirt length. 7. It is belived that Mini skirts are appeared and popularized by external factors. Once Mini skirts are accepted, we can expect that they will be continuosly changed in the course of recurring skirt length.

이 대담 시리즈는 학교도서관에 대한 도서관계 안팎의 관심을 높이고 현단계 학교도서관 운동이 나아갈 길을 모색해보려는 취지에서 시도된 것이다. 과거 학교도서관 운동을 주도하였거나 오랫동안 학교도서관 현장을 지켜온 인물들을 찾아 그들의 경험과 의식 속에 쌓여 있는 역사를 끌어내어 오늘을 비추어 보고 내일을 전망하는 계기로 삼을 것이다. 이번 대담에서 만난 사람은 우리 나라 학교도서관 운동의 초창기에 많은 활동을 한 조재후 선생이다. 선생은 부산중, 경남여고, 부산고 등에서 10년간 (1953-1963) 사서교사로 활동하면서 학교도서관 운동의 지평을 넓히는데 크게 기여하였으며 부산시 교육위원회 연구사 및 장학사(1963-1972), 문교부 중앙 시청 각교육원 연구관(1972-1973), 문교부 장학관 (1973-1975), 서울시 동부 교육구청장(1980-1982) 등으로 활동하셨다. 또한 영등포중, 혜화여고, 용산공고, 경기상고 등에서 교장으로 재직하시고 정년퇴임후 현재 서울 정화여자상업고등학교 교장으로 재직하고 계신다. 대담 일시 : 1998년 5월 2일 오전9시 30분 - 오전 11시 30분 대담 장소 : 서울 정화여상 교장실

The ever unsatisfied demand for more channel and bandwidth to the limited installalion of existing communication facilities, and explosively increasing expanses for the cable installation fee force us to revive once patented but unused idea of multlplexign in time, that is, PCM in telephony. The authors designed, artworked and prototyped PCM 24 since 1972 and tested the first PCM chaulel Hank between Noryang Jin and yang see stations to prove that the resust of their PCM 24 Channel Bank implementation is viable and promissing.

New malting barley variety" Doosan #8" is a short culm, lodging registance, high tillering, good quality and high yielding variety. This variety was developed from the cross 'Tai Chung 2 rowed barley #1 \times Deba abed' made in 1972 at Sacheon Malting Barley Experiment station, Doo San Fann's Co. This variety was determined to recommend to the all malting barley production areas in southern part of Korea from 1981. of Korea from 1981.

Fertilization and early development of turbo cornutus was studied based on the samples which were collected in Yeosu area. Particular emphasis was paid on induction of artificial spawing, fertilization rate, preembryonic development, the growth of the early larva and larval survival to various salinity. Among the various methods for induction of artificial spawning which have been tested for the present study, drying by exposure to air is the. most efficient, and percentage fertilization rate was $83.8-96.4\%$. The diameter of fertilized eggs was $0.182{\pm}0.0028mm$; and the diameter of egg membrane was $0.245{\pm}0.093mm$. Under the temperature range of $20.6-25.4^{\circ}C$ the larvae hatched out after 11:05-11:15 hours of fertilization. After 3.0-3.5 days of fertilization the planktonic larvae begand to settle, and the settlement terminated within 5 days. During the period of 150 days of early culturing the diameter growth of shell(M) and the diameter of shell aperture(A) was formulated as follows: $$1972\;M=0.33e^{0.02070D}$$ $$A=0.19e^{0.02282D}$$ $$1973\;M=0.32e^{0.02282D}$$ $$A=0.16e^{0.02596D}$$ During the same period of early culturing the relative growth of shell diameter and the diameter of shell aperture was formulated as follows : 1972 A=0.6478 S-0.1575 1973 A=0.5897 S-0.0515 After 11 days of larval hatching $0.02-0.18\%$ of planktonic larvae settled. After 150 days of settlement the survival rate of the early shells was $7.4-21.6\%$. Under the temperature range of $21.0-22.7^{\circ}C$ the optimum salinity range for the development of egg and the planktonic larvae was $30-35\%_{\circ}$.
