It is aimed to survey the housewive's interest and understanding on the Korean traditional dishes in relation to the importance and the significance of those dishes in the Korean traditional folk ceremony. Questionnaires were distributed to and answered by 667 housewives ranging from the the mother of kindergarden children to the mother of seniors in the university. Some of the significant findings and speculations derived from the analysis of data are summarized as follows: 1. About 90% of subjects have taken the knowledge on cooking the traditional dishes from their mothers and their grandmothers. And they have had many opportunities to known about traditional dishes through the home life education. 2. The kinds of the Korean traditional dishes which are used often at the folk ceremony are Tto k(Korean rice cake), Shikhae (fermented rice fruits punch), Sujong Kwa (persimmon fruits punch), Whachae(flower, fruits punch) etc. 3. About two thirds of the subjects have a little knowledge about Korean traditional special menu for the Korean folk ceremony, however, most of them observe New York's Day, Chusuk (The Korean Tranks giving Day), Dongji (The winter solstice), and Deborum (The 15th of the January on lunar Calender). 4. About 74% of the subjects use Korean traditional foods when they have Korean traditional folk ceremony. But there is a tendency to use nontraditional dishes among young housewives. 5. More than 73% of the housewives agree to the idea that Korean traditional dishes have to be succeeded and developed. 6. Most of the housewives think the Korean traditional folk ceremony is important and they are willing to make Korean traditional foods on the occasions, but they also think the ceremony must be rather simplified.

This study was surveyed the preference for the regional food and food choices according to Region, Age, Sex. The subjects were 943 residing in Seoul and Cheon Nam region. The summarized result are as follows; The survey about the preference for the regional food showed that subjects in Cheon Nam has higher preference for the Cheon Nam food and subjects in Seoul for the Seoul food respectively. The most subjects marked very high preference scores about familiar food. The preference for the regional food and food choices were effected by main growth region. Subjects brought up in Cheon Nam like Cheon Nam food especially fresh raw fishes(WHOI) and fermented fishes(CHOT GAL) more than those brought up in Seoul, although both of them reside in Seoul now. But they were brought up in Cheon Nam, subjects residing in Cheon Nam or Seoul now showed no difference in preference for Cheon Nam food. Subjects in Cheon Nam showed higher preperence for fresh raw fishes(WHOI), fermented fishes(CHOT GAL), especially in older men.

The survey was carried out to obtain some fundmental data to improve the dietary life and to establish the nutritonal education and policy on inhabitants lived in isle area near by demilitarized zone in Korea. For this, 33 families in the area of Kyodong island located at Kanghwa-Gun, Kyungki province were randomly selected. Trained surveyors visited each house to survey the food and nutritional status in summer during 3 days in August, 1987. The results are summarized as follows; The number of foods they were taking totalled 17 categories and 134 kinds of which 104 kinds were vegetable foods. The average amount of food intake was 1465.3g per person per day, animal food occupied 9.6% only. The intake amount of fruit among vegetable foods, and fishes, shells, milk and eggs among animal foods was lower than the national average. Each proportion of carbohydrate, fat and protein to the total energy intake was 70.4%, 9.7% and 19.9%. The foods they used to take a lot were rice, potatoes, cucumbers, cabbage KIMCHIE and YULMOO KIMCHIE in order of their intake amount. The energy intake was 3064㎉ which is higher than nutritional requirements, and the energy ratio of cereals to the total energy in take is 76%. If the amount of fat intake is fixed to 20% of total energy intake, the amount of fat intake is 68g, but the actual amount of fat intake was only 33g. With an increase of total energy intake, supply of calcium and vitamin A should be increased much more.

The physical properties of sedimentary rocks in the coal fields were studied. Sandstones and shales are major samples among the core samples from Samchuck and Boeun coal fields. The measured properties were seismic velocities (P and S-wave), electrical resistivity, density and porosity. The relationships between physical properties were analyzed by using the cross plots. Summarized results are as follows : 1. Compressional wave velocity is approximately linearly related to shear wave velocity and the velocity ratio Vp/Vs of shales has slightly larger value than that of sandstone. And with increasing Vp, the velocity ratio Vp/Vs decreases because the effect of porosity and clay content on Vs is larger than on Vp. 2. In the case of sandstones, as porosity increases, P-wave velocity decreases slowly, but effect on the density is not apparent. In the case of shales, as porosity increases, both P-wave velocity and density decrease. 3. The values and variation range of density of sandstones are relatively small as compared to those of shales. But the range of elastic wave velocities of both rocks are appeared to be similar. 4. Seismic velocity is power-functionally related to electrical resistivity, and the value of the power is appeared to be larger for sandstones than for shales. 5. Because samples from Boeun field are slightly metamorphosed, the values of electrical resistivity are larger than those of samples from Samchuk field.

Cretaceous plutonic rocks distributed in Yuga and Seongsan.myeon are of quartz monzodiorite,granodiorite and monzogranite(granite B) in rock types. The modal composition changes systematically and each plutons are divided into the two rock types convenienly, ie. intermediate and acidic rock types:The intermediate rock is composed of quartz monzodiorite mainly and granodiorite, whereas the acidic rock is composed of monzogranite mainly and quartz monzonite. Zirocons are prominently included in plagioclase of the rock forming minerals in the intermediate rock, whereas in the acidic rock, in hornblende and biotite of the rock forming minerals prominently, The amounts of the included zircons are related to the relative amounts of plagioclase or hornblende and biotite in the two rock types. In the ratio of the included zircons of the main rock forming minerals, those of plagioclase are narrowly constant, whereas those of hornblende and biotite are broadly change in the two rock types and the latters in the acidic rock are higher than those in the intermediate rock. The size of zircon grains gradationally decrease from the intermediate rock parts to the acidic rock. From the frequency distribution of lenghth and breadth, those of the intermediate rock are bimodal or polymodal, and those of the acidic rock are unimodal shape. From these fact, it is suggested that the two rock types are comagmatic origin, but zircon concentrates of each rock type may have been crystallized under some different magmatic environment in the physico-chemical condition.

The principal consisting rocks of study area are Precambrian metasedimentary bedrocks, Cambro-ordovician sedimentary rocks and Samhwa granite which have intruded these metasedimentary and sedimentary rocks. The reddish K-feldspar bearing Samhwa granite presettts miarolitic texture and graphic intergrowth between quartz and K-feldspar. The granite, homogeneous in chemical composition of major elements, belongs to Calc-alkali rocks of subalkali series. According to AMF diagram, the granite was crystallized at the latest stage of the differentiation of magma. The Samhwa granite belongs to I-type granitoids and magnetite-series granitoids. Especially, this granite is thought to be crystallized in the epicrust with high oxygen fugacity. The Samhwa granite has similar characteristics to masanite of cretaceous granitic rocks of Gyeongsang basin in the petrological and petrochemical properties. The biotite age of the granite by K-Ar age dating is 50.1±1.5. Finally, contact metamorphic zone of limestone by granite intrusion contains distinct minerals such as diopside, brucite, tremolite and muscovite, which indicate low temperature metamorphic grade.

보은군 회남면 조곡리에는 옥천계 누층군내에 감람암의 노두가 발견되며 이 암석의 밀도는 2.9∼3.1 g/㎤로서 주변암석 보다 0.3g/㎤ 이상 크기 때문에 중력 탐사에 의한 감람암의 지하연장 규모를 추정할 만 하다. 본 지역과 주변지역에서 정밀측정을 실시한 결과 중력 이상치는 서측에서 18mgal, 동측에서는 8mgal 정도로 지역적 경향을 보이며 이로부터 분리한 국지적 중력이상은 감람암 노두지역 부근에서 4,3mgal 정도이다. 이를 분석 연구하여 감람암체가 약 3㎞ 이내의 뿌리를 갖고 있으며 지하로 들어갈수록 서측으로 경사되어 있음을 알 수 있었다. 따라서 감람암체는 현 위치에서 맨틀로부터 상승 분출했다기 보다 이미 분출된 후에 지각변동을 받아 이동된 듯하다.

발효 원리에 의한 젓갈 담금법은 크게 젓과 식해로 구분된다. 젓은 9가지로 (1) 소금, (2) 소금 고추가루, (3) 소금 익힌 곡류, (4) 소금 고추가루 곡류, (5) 소금 메주가루, (6) 소금 누룩가루 콩가루, (7) 간장, (8) 젓갈, (9) 소금물 등에 담그는 것이다. 식해는 14가지로 (1) 쌀밥 소금 엿기름, (2) 쌀밥 소금 엿기름 밀가루, (3) 쌀밥 소금 고추가루 엿기름, (4) 조밥 소금 고추가루 향신료, (5) 쌀밥 소금 고추가루 엿기름 향신료, (6) 조밥 소금 고추가루 엿기름 무우채 향신료, (7) 조밥 소금 고추가루 무우채 향신료, (8) 쌀밥 소금 밀가루 고추가루 엿기름(설탕) (향신료), (9) 쌀밥 소금 고추가루 무우채 향신료 엿기름(설탕), (10) 찰밥 소금 고추가루 향신료, (11) 소금 무우채 고추가루 향신료, (12) 찰밥 소금 고추가루 엿기름 향신료, (13) 찰밥 소금 고추가루 엿기름 무우채 향신료, (14) 밀가루죽 소금 고추가루 엿기름(무우채) 향신료 등으로 담그는 것이다. 젓 담금법의 지역적 특색은 관서지방에서는 갑각류 중 게를 소금물에 담그는 가정이 많았고, 중부지방에서는 부족류 및 복족류 중 굴을 소금 고추가루, 소금 고추가루 익힌 곡류로 어리굴젓을 담그며 남부지방에서는 갑각류 중 민물새우를 소금, 소금 고추가루, 소금 익힌곡류, 소금 고추가루 익힌 곡류로 담그며, 관북지방에서는 어류를 소금 고추가루로 담그는 것을 알 수 있다. 식해 담금법의 지역적 특색은 우리나라의 동부지역에서 담근다. 이것은 동해에서는 사계절 생선을 잡을 수 있으므로 구태여 오래 보존해 둘 필요가 없기 때문이며, 또한 동해안은 소금 생산량이 적기 때문에 소금이 풍부한 서해안에서는 젓이 발달하고, 소금이 부족한 동해안에서는 식해가 발달하게 된 것임을 알 수 있다. 식해 담금법 중 엿기름을 넣어 담그는 곳은 남부지역이고, 무우채를 넣어 담그는 곳은 관북지역이며, 관북지방보다 남부지방에서는 익힌 곡류의 양을 많이 넣는다. 고추가루는 관북 남부 모두 넣으나, 남부지방에서는 제찬용 식해에는 넣지 않는다. 식해에 넣는 곡류의 종류는 그 지역에서 생산이 많이 되는 곡류를 사용한다.

In 1985 and 1986, silage productivity of 8 Korean improved and 7 US introduced corn hybrids and their resistance to rice black-streaked dwarf virus (RBSDV) were tested in the southern part of Korea where RBSDV is prevalent. The results obtained are summar

북한산지역의 삼림군집구조를 분석하기 위하여 식생상관 및 식생층별 nested quadrat method에 의하여 설치된 20개 조사구의 식생조사를 하였다. 교목상층의 우점종에 의한 삼림군집의 유형은 소나무와 신갈나무의 순림 또는 혼효림을 주로 하는 자연식생군집, 자연식생과 인공식생이 혼효하고 있는 반인공식생군집, 인공식생이 순림 또는 혼효림을 이루고 있는 인공식생군집으로 구분할 수 있었으며, 북한산지역 전체에 대한 면적구성비는 각각 82.64, 7.03, 5.71%이었다. 소나무와 신갈나무의 순림 또는 혼효림은 면적구성비가 전체면적의 70.8%로서 대표적인 식생이었다. 인공식생의 주수종은 아까시나무, 리기다소나무, 물오리나무 등이었으며 주로 토양침식이 비교적 심한 남사면과 도로 등 시가지와의 경계부에 식재되어 있었다. 녹지자연도 8, 7, 6의 면적구성비는 각각 82.6, 0, 12.7%이었다. 임분구조는 국소적으로 분포하고 있는 소나무, 상수리나무 장령림, 아까시나무림을 제외할 때 대체로 교목상층의 평균흉고직경, 임관고가 각각 20cm, l0m 이하로써 유령림상태이었다. 북한산지역의 대표적인 자연식생군집인 소나무와 신갈나무의 순림 또는 혼효림의 종다양도는 1.085~l.242의 범위를 보였다. 주요 수종의 직경분포에 의한 동태 분석 결과 기존 신갈나무군집과 아까시나무군집은 현재의 천이단계가 지속될것으로 추정되었으며, 타군집의 경우 전반적으로 신갈나무군집으로 천이가 진행되고 있었고, 국소적으로 아까시나무가 침입하고 있는 군집과 갈참나무-상수리나무군집의 경우 각각 아까시나무군집, 갈참나무군집으로 진행되고 있는 경향을 보였다. ordination 방법중 DCA 방법이 본 연구에서는 가장 효과적이었으며, DCA에 의해 추정된 천이과정은 교목층인 상층은 소나무→졸참나무, 산벚나무, 팔배나무→신갈나무, 들메나무, 물푸레나무의 순이었고, 중층은 산초, 참싸리→개옻나무, 옻나무, 생강나무, 진달래, 철쭉→당단풍, 함박꽃나무, 참빗살나무의 순이었다.

This paper is a part of the regional characteristics of Korean chotkal. The kinds and materials of Korean chotkals are studied by interviewing local people living in 142 different regions which are bigger than 'myon' in size. Regions are classified according to the structural style of commoner's house. Regional characteristics of chotkal are analyzed and interpreted with natural environmental factor. The rest of my further interested subject will be followed in later issues ; the ways of preservation, period of fermentation according to the regional characteristics and uses of Korean chotkal. The results of this study can be summerized as follows, 1. There are 145 different kinds. 2. Raw materials of 145 kinds of chotkal are devided roughly into five groups ; (1) fishes in 87 kinds (2) Pelecypoda and Gastropoda in 14 kinds (3) Cephalopoda in 10 Kinds (4) Crustacea in 32 kinds and (5) Holothuroidea and Echinoidea in 2 kinds. They can also be classified according to the parts of individual material ; (1) body or flesh in 118 kinds (2) internal organs in 15 kinds and (3) eggs in 12 kinds. Regions are devided into four provinces ; 'Kwanso', 'Chungbu', 'Nambu', and 'Kwanbuk' in which the number of different kinds of chotkal are 32, 41, 99 and 34, respectively. Raw materials vary because of the distribution of marine life in different regions. Fishes and Cephalopoda are used in all four regions, Pelecypoda and Gastropoda in 'Kwanso', 'Chungbu' and western part of 'Nambu' regions. Different species of Crustacea used in each different regions ; sea crab and sea shrimp in the western coastal area, fresh water crab in the field area, fresh water shrimp in 'Chollado', mantis crab at 'Shihung-gun' in 'Kyonggi-do', Holothuroidea and Echinoidea are used in 'Nambu' regions. Chotkal are not used at all in six local districts which are located in inland areas where the transportation is inconvenient.

The deflection of the vertical and the geoid height in the southern part of the Korean peninsular were computed from gravity anomalies by the application of the Fourier and Bessel-Fourier series. The deflection of the vertical computed from free-air anomaly has highest values of 7∼8$quot; around the central part of the Taebaek and Sobaek Mountains. The general direction appears to be nearly perpendicular to the NNE-SSW direction of the general tectonic structure of the peninsular. The geoid height increases to the south-east direction and the difference on the peninsular is about 3 m. The undulation of the Bouguer geoid appears to be correlated with the crustal thickness, having highest values on the eastern and southern coasts. The geoid height computed by using the geopotential coefficients up to the 16th order obtained from the spherical harmonic analysis of the satellite data shows similar trend of increase but much higher value than that of free-air geoid.

1985년 1월 28일부터 7월 20일까지 한국어업기술훈련소(Lat. 35˚05'04N, Long, 129˚02'13E)에서 NNSS로 연속관측하여 관측시간, 위성별, 앙각, 통과방향, doppler count 수, 안테나의 높이 등이 NNSS위치의 정도에 미치는 영향을 분석.검토한 결과는 다음과 같다. 1. 위성항법에서 사용하고 있는 WGS-72 측지계를 Bessel측지계로 변환하여 계산하면, 편위오차를 평균 0.21마일 정도로 줄일 수 있음을 알 수 있었다. 2. 산정의 앙각이 높을 때 측위정도가 높았고, 위성의 앙각이 20~70도 범위에서 더욱 높았다. 3. Doppller count 수가 21번 이상일 때 측위거리의 오차도 커지는 경향을 나타내었으며, 위성의 종류에 다른 측위오차의 변동은 거의 없었다.
