The purpose of this study is to interpret a house as material into culture. Main method is an ethnographic interview with dwellers as a part of a participant observation, a kind qualitative study. Significantly two different types of folk housing are discovered in East and West areas of the Cheju Island. In the East, kitchen itself forms a separated building, Jeongji-gori, whereas in the West, kitchen is within a main building, An-gori. Different type of kitchen is formed by the different family system. While independent family system of son and father selects a separate kitchen building as a general rule of Cheju Island, an extended family system between father and son selects same kitchen, Jeongji-gori, in the east area. Natural environment of infertile soil of east area makes family work together and eat together. Inner space of the kitchen building is utilized not only in cooking but also in eating, working, and sleeping. In order to explain folk house type, a 'culture area' concept is suggested. The interrelated 'cultural type' of architecture behind a physical surface 'type' is suggested as a new typology.

1996년 여름 제주도 서쪽 해안에서 전에 볼 수 없을 정도로 유용 대형저서동물이 대량으로 죽어, 전복, 오분자기, 소라, 해삼, 말똥성게에 큰 피해를 주었다. 제주도 해안에서 식물플랑크톤 대발생은 없었고, 대량폐사가 일어나기 전에 해안에서 표층 저염수가 나타났기 때문에 저염분 스트레스가 대량폐사에 결정적인 영향을 미쳤을 것으로 여겨진다. 같은 기간 관측된 강수량이 적어, 강수량으로 저염화를 설명하지 못한다. 국립수산진흥원(1997)이 관측한 자료는 1

This paper is second part on the auditory thresholds and fish behaviors to the underwater sounds for luring of target species at the set-net in the coast of Cheju. In order to obtain the critical ratio of yellow tails(Seriola quinqueradiata) and the emission level of underwater sound for luring of them, we make experiments to measure the auditory threshold of them using conditioning with electric shock. In state that the white noise with 10dB higher sound pressure level than ambient noise is emitted, the auditory thresholds of yellow tails are measured with 100~116.5dB and they are higher than those in state of no emission of white noise by the masking effects of it. Although sound pressure level of background noise go down, the auditory thresholds go up with frequency above than 300Hz.The critical ratio of yellow-tails in frequency of 80Hz, 100Hz, 200Hz, 500Hz, 800Hz are 46dB, 40dB, 50dB, 52dB, 60dB, 70dB respectively. The sound pressure level of which the signal sound is recognized by yellow tails under the ambient noise is above 100dB and the critical ratio of them is above 40dB.

꽃양배추와 녹색 꽃양배추를 가지고 제주지역의 기후를 이용하여 합리적이고 양질의 생산기술을 개발하기 위해 적품종선발. 정식적기 판정, 무가온하우스 효과 등을 시험하였다. 꽃양배추 중에 Snow king과 Snow crown품종은 조생종으로서 초기 영양생장이 활발했지만, 화구의 형질이나 비타민 A와 C의 함량은 Snow dress가 많았다. 푸른꽃양배추와 비타민 분석결과 New green품종이 높게 나왔지만 초기 생육이나 상품성에서는 Green beauty가 제주지방에서 재배 가능한 품종임을 알 수 있었다. 꽃양배추와 녹색 꽃양배추 전 품종에서 10월 1일 정식한 구보다 9월 3일과 17일에 정식한 구가 정식일로부터 수확일까지의 소요기간이 짧았다. 수확물비교에서 꽃양배추는 정식기별로 유의차가 거의 없었고, 녹색 꽃양배추에서는 10월 1일 정식한 구가 상품성이 높았다. 꽃양배추의 경우 만생종인 Snow dress를 무가온 하우스에서 재배하면 생육기간을 대폭 줄일 수 있었고 녹색 꽃양배추는 비교적 노지와 무가온 하우스 재배가 비슷하였다. 꽃양배추와 녹색 꽃양배추 모든 품종에서 비타민 A와 C 함량은 노지와 무가온 하우스 재배간에 유의차를 보이지 않았다. 꽃양배추와 녹색 꽃양배추를 무가온 하우스에서 재배하면 화구중은 감소하고 화구폭은 증가하는 경향을 나타냈다

현재 제주도 서귀포시 제주감귤연구소에서 개발중인 내풍형 2중 아치 비닐하우스에 풍하중을 재하하여 탄성수치해석을 시도한 결과, 풍동실험에 의하면 파풍망의 효과는 풍속이 5∼25m/s 일 때 파풍망을 통과한 유출속도가 86∼98%까지 감소하여 매우 효과적임을 알 수 있었다. 본 연구에서는 일반적으로 사용하고 있는 파이프를 지반에 고정시키는 경계조건을 주지 않고 설치한 피라미드형 콘크리트 지지대의 사하중을 지점에 재하하여 경계조건을 준 결과, 하우스가 풍하중의 양력에 의하여 위로 들리는 거동을 나타내고 있었다. 이러한 거동은 현장에서 목격되는 파괴형상이 기초 전체가 인발되고 파이프가 콘크리트 기초로부터 인발됨으로써 야기되는 파괴요인이 된다. 본 연구에서 재하한 45m/s의 풍하중은 재현기간이 100년에 대한 값으로 반영구적인 구조물에 기준으로 비닐하우스의 내구수명이 상대적으로 짧으므로 이 풍하중을 감소시켜서 설계할 수 있었다. 또한 본 연구에서는 지붕아치가 연결되는 Y-형 접속장치를 내부힌지로 모델링한 것을 제외하고는 모든 연결을 고정연결로 보아 해석하였다.

This survey was conducted to investigate the relation of children's obesity index to their mothers' food habit during the October in 1995. The survey covered a total of 492 mothers whose children were in the fifth grade of elementary schools in Cheju City area. The results are summarized as follows: 1.The surveyed children's average WLI(Weight-Length Index) is 107.08. WLI shows that 16.1% of them are overweight, 16.1% obese and 49.8% ideally weighted. The mothers' average BMI(Body Mass Index) is 22.4. 21.8% of them are underweight and 69.4% normal. The children's obesity index is significantly correlated to their fathers', but not significant to their mothers'. 2.As to the food habit I (balance of nutrients intake), 58.4% of the mothers have 'excellent' or 'good' food habit and the mean score is 14.95 out of maximum possible score 24.0. Concerning to the food habit II (intake of sugar, fat and salt etc.), 87.4% of mothers have 'good' or 'fair' food habit and the mean score of is 13.34 out of maximum (possible score) 20.0. The mothers' food habit I and II, as a whole, have no significant effect on the children's obesity index, but in some items the significant relations are founded. The children's chesty index is significantly related to the intake of eggs (P<0.05) and pan-broiled or fried foods (P<0.05). The amount of mothers' food intake is significantly relevant to their obesity index (P<0.001), but not significantly to their children's. The food habit of mothers who have taken midnight snack almost every day are significantly related to their children's chesty index (P<0.05). The findings of the study emphasize the importance of the nutrition education to ensure health and better physical fitness for children and their mothers.

The study on the Assembling Mechanism of the Hairtail, Trichiurus lenpturus, at the Fishing Grounds of the Cheju Strait had been investigated by analyzing the relationship of the oceanographic conditions and the fishing ground of the Hairtail in the Cheju Strait. 1. The fishing grounds of the hairtail at the Cheju Strait are formed at the bottom of a high temperature of the tidal front at the coast. area of northern Cheju Island, the tip of the linguiform is high in salinity at the eastern and western entrances of Cheju Island, low salinity eddy on the surface and its surrounding front, various water masses in the Strait and coastal waters of the South Sea in Korea. 2. The fishing grounds of the Hairtail at the Cheju Strait begins with the sea surface temperature higher than 15℃ and the incoming of low salinity water now from the East China Sea. 3. Estimation of optimum temperature and salinity per season based upon analysis for relationship between temperature of water and salinity of the bottom layer and the catch is : 15.2~16.4℃, 34.20~34.40‰ in spring(June); 14.4~ 17.0℃, 33.70~34.30‰ in summer(July~September); and 15.7~ 18.6℃, 33.70~34.50‰ in autumn(October~December). Hairtail are mostly caught at the Yellow Sea Warm Current and Tsushima Current with temperature over 14.5℃ and salinity over 33.70‰ at the bottom layers of the Cheju Strait. 4. Considering the relationship between the amount of hairtail catch and the water temperature of bottom layer, when the bottom water being above 14.0℃ flowed into Cheju Strait through the western entrance of the strait in summer, the ca-h appears to have been abundant. In contrast, the catch has been poor when the temperature of such water was recorded to be below 13℃ Therefore, distribution patterns of water at the bottom layer can be used as a forecast index whether the catch of a certain year will be good or poor.

The distribution and abundance of fish in the Cheju southeastern area was studied by the combined hydroacoustic and bottom trawl surveys in April 1994 and in July 1995, respectively. The main purpose of these investigations was to provide the basic data for this management and the biomass estimation of commercially important demersal fish stocks in this area. The hydroacoustic surveys were performed by using a 50 kHz scientific echo sounder system with a microcomputer-based echo integrator. Acoustical measurements of fish abundance and distribution were conducted along the cruise tracks of research vessel and during all trawl hauls by continuous echo sounding. The average weight-normalized target strength for demersal fish aggregations was derived from the relationship between the mean volume backscattering strength for the depth strata of trawl hauls and the weight per cubic meter of trawl catches. The geographical distribution of fish stocks in the 1994 survey area was investigated in relation to oceanographic conditions. The results obtained can be summarized as follows: 1. From the 1994 and 1995 survey data, the relationship between the mean volume backscattering strength (〈SV〉, dB) for the depth strata of trawl hauls and the weight (W, kg/m3) per cubic meter of trawl catches was expressed by the following equation 〈SV〉 = - 32.8+ lOlog(W) The average weighted-target strength value at 50 kHz derived from this equation was .. 32.8 dB/kg. 2. In 1994 and 1995, both surveys showed a trend of decreasing fish abundance toward the southern area of the Cheju Island with high densities offish along the west coast ofth.e Tsushima Island. The highest demersal concentrations in the southern area of the CheJu Island appeared in bottom waters colder than 12℃.. . 3. From the results of combined bottom trawl and hydroacoustic surveys, the estunated fish densities in the southeastern area of the Cheju Island were 1.5488 x 10-4kg/m3 in the 1994 surveyand 1.9498 x 10-4kg/m3 in the 1995 survey, respectively.

The combined hydroacoustic and bottom trawl surveys were conducted in the Cheju southeastern area by the training ship "KAYA" belong to Pukyong National University in July 1995 and the traning ship "NAGASAKI MARl]" belong to Nagasaki University in April 1994, respectively. The main purpose of the investigations was to provide the basic data for the management and the biomass estimation of commercially important demersal fish stocks in this area. Fish samples were collected by bottom trawling from 10 trawl stations randomly selected in the survey area, and the species and length compositions of trawl catches were examined. The fish school target strength for demersal fish aggregations was related to the catchability of trawl net with a 90 mm mesh codend. The most abundant species in the 1995 trawl stations were Japanese flying squid, sword tip squid and red horsehead and that of the 1994 trawl stations Japanese flying squid and blackmouth goosefish. The average weight per cubic meter of trawl catches collected by bottom trawling in the Cheju southeastern area were 1.0791×lO-4kg/m3 in the 1994 survey area and 1.3636×lO-4kg/m3 in the 1995 survey area, respectively. The catch data by cover net suggest that the efficiency of trawl net could affect the weight normalized target strength values for demersal fish aggregations. That is, the average target strength per unit of weight dropped from - 33.1 dB/kg using the total catch by codend and cover net to - 30.5 dB/kg using only the catch data by codend, and a change of2.6 dB/kg was observed.ange of2.6 dB/kg was observed.

Plasma progesterone concentrations were measured by using radjoimmunoassay for early diagnosis of pregnancy in Cheju-native mares. A total of 226 pony mares were examined for pregnancy during breeding and non breeding seasons. Plasma progesterone levels 20~23 days after the onset of oestrus were 4.67+O.67ng /rnl and O.55+O.O4ng /ml for mares becornrning pregnant and not pregnant after the estrus, respectively, and there was a significant differences (p<0.01) between the two groups. Progesterone concentration of pregnant mares gradually increased in 30 days andreached a peak (10.3ng /ml) during the third month of gestation. However, the concentration decresed to the base line (1.llng /rnl) at 7 months and gradually increased again as foaling approached (2.lng /ml). Early diagnosis for pregnancy of Cheju mares by progesterone level at 20~23 days after onset of oestrus was 88% accurate when 4.6ng /ml was used to classify mares as pregnancy and below 1.3ng /rnl was used to determine nonpregnant mares. However, the accuracy of the diagnosis was improved to 96% when a progesterone level of above 2ng /mi was used to classify mares for pregnancy. Diagnosis for pregnancy was 69.6% accurate when mares were classified as pregnancy by horse owners during breeding season. The progesterone levels of pregnant and non-pregnant mares during non-breeding season varied greatly between individual animals, Plasma progesterone levels of pregnant animals ranged from 3.5ng /mi to above 6.2ng /mi whereas similar values were observed in non-pregnant animals. Radioirnrnunoassay technicjues can be applied for the early pregnant diagnosis of Cheju native mares when progesterone levels are measured during the early gestation period (18~23 days after onset of oestrus). However, progesterone concentration of mares in non-breeding season is conisidered unsuitable as a indicator of pregnant diagnosis.

This study aims at exploring the nature of the traditional Korean wines brewed throughout the Southern Region of Korea-Chulla-do, Kyungsang-do and Cheju-do describing their varieties and brewing methods and also comparing the similarities and differences of their features. When compared with the wines produced in the Central Region, the Southern varieties are very fastidious and complex in their brewing methods, which in turn show a wide range of diversity. First of all, all the 29 kinds of wines investigated, not a single one shows any resemblance to any one of the remaining, each exhibiting peculiar and particular characteristic features of its own. Especially, the distilling methods demonstrate very complex processes. Secondly, the majority of the Southern spirits are made from grains, added with fragrant flavor of pine tree, wormwood, chrysanthemum leaves and other medicine herbs such as Chinese matrimony vine and tankui. Thirdly, they are brewed with yeast made from wheat into kodupap(steamed rice) type of spirits, emerging as in the form of blended liquor. Fourthly, in brewing, different fermenting temperature and duration are required. Typewise, the temperature required for the basic spirit is 15~20℃ or 25~30℃ : in the case of blended secondarily fermented liquor, from the minimum of 0~5℃ to the maximum of 75~80℃. The brewing duration is 3~5 days for the basic spirits. In some cases, from the minimum of 3 days to the maximum of 100 days are consumed for fermenting. Fifthly, the wine extraction gadgets are yongsu (wine strainer), the sieve, filter paper, Korean traditional paper, the utilization of which implies that the brewers endeavor to observe and preserve the traditional and indigenous methods of wine making.
