In the meantime, the study of traditional and contemporary house had been produced so many achievements in korea, but modern house is yet to be solved, Accordingly, It is necessary to develop and present the basic research data in order to build up an objective study for urban house in the modern age(1910-1945), Following to a study on the foreigner's house in grid-type settlement of Open Ports, in this research is to investigate and analyze modern houses of urban areas in korean inland, and then clarify types and changes of them. In the first year($1995{\sim}96$), the modern houses of Central Inland Districts(arrounding river Kumgang)-Kunsan kanggyong Puyo Kongju Pugang Chongju were investigated by the layout of room, the construction and materials, the design and style, etc. In the second year($1996{\sim}97$), the modern houses of Open Market(開市場)-Seoul Taegu Kwangju Taejon Chonju were conducted to investigate as above. The traditional house transformed by differentiation and addition of room(kan), the various types were respectively adopted for the korean reforming and western cultural house. In the layout of room, the types of plan were gradually concentrated from the single wings of korean traditional house. The korean traditional house was later improved through the introduction of entrance, corridor, and internal toilet/bathroom. But the korean under-floor heating system(andal) and a series of three rooms had been entirely maintained, composed of master bedroom/living room(daechung)/room. And the traditional town house with shop and storage, being built closely to each other and walled up both sides, it had taken gradually the extensive characteristics in itself. By the displacement of shop/dwelling/ storage. the various types were respectively adopted for the separated, multi-storied, and complex type. The type of them was gradually changed to the narrow and linear form. And so with the stockpile of fundamental datas about modern houses in korean urban areas, we expect these results contribute to the knowledge of the spatial characteristics of urban house at present which are required to the understanding of transition as well as types.

The study is to derive a typical probable rainfall intensity formula(TPRIF) by analyzing pre-issued probable rainfall intensity formulas (PPRIF) over principal rainfall observation stations, and to obtain the regional characteristics based on the rainfall patterns by evaluating probable rainfall amount. The conclusions are as follows. A TPRIF which integrates PPRIF with a single pattern is presented. In deriving probable rainfall intensity, the application of TPRIF was more excellent than that of PPRIF. The value of R24/Rl which is the dimensionless ratio for rainfall characteristics tends to be inversely proportionate to the regional coefficient n. By comparing these values, the whole country could be divided into about 5 regions. In these five regions, the short-duration rainfall intensity is dominant in inland areas but the long-duration rainfall intensity is dominant in East Sea areas.

The interannual fluctuation, trends and perio-dicties in summer rainfall of South Korea were analyzed primarily by using Mann-Kendall rank method and Power Spectrum analysis for the period from 1920 to 1985. Their relations to Indian summer monsoon rainfall have also been examined. Increasing or decreasing rainfall tendencies are not found in South Korea. In Power Spectrum alalysis, 2.5 years periods are predominent at the 95 per cent confidence level in south Korea as a whole and Pusan. Also the period of 11.0 years is found in Seou. There are another prominent spectral peaks at 2.4, 3.1, 6.2 and 7.3 years period, which are significant at 90 per cent confidence level.

대구시는 여름철을 제외하고 서북서풍내지 서풍으로 서풍계열의 바람이 우세하여 지리적으로 서쪽에 위치한 공장지대와 신흥 부도심의 영향이 도심지 내부에 크게 나타날 수밖에 없는 그런 구조를 가지고 있으므로 도심내의 녹지공원 조성과 같은 오아시스 효과로 자연형 대기 순환 구조를 구축하지 않을 경우 환경오염과 지구온난화로 인한 심각한 피해가 초래할 수 있으므로 친환경도시를 위한 준비를 소홀히 해서는 않된다고 사료된다. 아울러 대구광역시의 연평균 대기오염물질의 농도는 $PM_{10}$, $NO_2$ 제외하고 환경기준을 초과한 것은 없으며, 주로 자동차와 주변 공장에 의한 오염원이 대부분임을 알 수 있었다. 또한 $PM_{10}$의 경우 대구시에 산재한 환경측정만 대부분의 지점에서 환경기준을 초과하고 있으므로 디젤 자동차 및 비산먼지 저감 등 미세분진에 대한 저감 대책을 신속히 마련하여야 한다고 생각한다. 그리고 대구시의 $O_3$과 $PM_{10}$의 고농도 현상은 고기압이 장시간 우리나라를 지배하면서 대기가 안정되고 바람이 약하여 국지풍의 발달이 용이할 경우 도심지내에 고농도 오염을 야기하고 있으며 지형적으로 도심의 오염물이 다른 지역으로 수송되거나 확산이 용이하지 않는 지형구조를 갖고 있으므로 도심을 흐르는 신천을 바람통로 이용하고 도심에 녹지공간 형성 및 도심지의 불투수성 지표면을 잔디 이식을 통한 자연형 도로로 바꾸어 줌으로서 도심내의 열 축적 현상을 줄이고 증발산을 도울 수 있는 cold island 역할을 증대시킬 수 있을 것이다. 이와 같은 사업은 풍속이 약하고 건조한 독일을 포함한 유럽의 내륙지방에서 활발하며 최근에는 해안에 있는 대도시에 저온의 해풍 또는 강바람을 도심에 유입시켜 도시열섬을 완화하고자 하는 시도가 일본을 포함한 아시아 국가에서 많은 관심을 가지고 있다(Ichinose, 1999, 2000; 김해동 외, 2002).

Some climatological features of summer precipitation in Korea were studyed using the precipitation data of 15 stations of Korea Meteorological Administration where more than 30 years data since 1961 are available. The study included statistical analysis of precipitation by climatological normal values, and comparison of inter-annual variation of annual precipitation, summer precipitation and precipitation during the Changma. The relationships between them were also analyzed. It was revealed that, in Korea, more than half of annual precipitation was concentrated in summer season (June to August), and it was usually influenced by the Changma. The ratio of summer and Changma precipitation to the annual precipitation showed that effect of Changma was bigger in the central inland area, while comparatively smaller in the east coastal area and Cheju Island due to topographical effects. It was also shown that the fluctuation of the annual precipitation was less variable than those of summer and Changma precipitations. Thus, it was suggested that understanding the variation features of summer precipitation associated with monsoon activities was very important to figure out the change of annual precipitation for the national water resources planning.

Using the meteorological data, surface weather map, and oceanographic data for 5 years(1984-1988). I investigated the characteristics of the fog occurrence and the role of the inshore in Pusan about the fog occurrence. And the meteorological data and sea surface temperature(SST), which were observed in July, 1989 in Suyoung Bay, were compared with those in Pusan. The fogs in Pusan concentrate in May, June and July. And at fog occurrence time the principal wind directions are Southwest(SW) winds, which easily supply with water vapor, and a series of Northeast(NE) wind. At the fog days pressure patterns are pattern 7 in spring time (March, April, and May) and pattern 10 and pattern 13 in summer time (June, July, and August). Also the advection fog(sea fog) is closely related with the relationship between warm and cold advection in 850~700mb and cold and warm SST rather than the increase of the instability of atmosphere in 850~500mb. The fogs in Taegu, which is the inland region, mainly occur at dawn in fall time due to the strong night radiation fog. On the other hand in Pusan the coastal region, the fogs occur from late spring time to summer time (May, June, and July). Because there is the abundant supply of the water vapor from the ocean owing to a series of South(S) wind at this time. Then the atmosphere, which has high relative humidity, reaches easily the supersaturation by the radiation cooling. In Suyoung Bay and Pusan the meteorological observation data, SST and fog days are almost similar. And I think that the mechanism of the fog occurrence nearly accords with both regions.

The applicability to Korea is examined of a pond system which treats and recycles wastewaters. Air temperature and solar radiation of the pond systems at Corinne, Utah, and Eudora, Kansas, which are located in temperate regions of the U.S., are compared with those of Kimpo lying in the mid-western part of Korea. Analyzed are also $BOD_5$ and SS concentrations, algal concentrations, pH levels, and water temperature of the two systems. Air temperature of Kimpo is quite similar to that of the two systems, and solar radiation of Kimpo is more conducive than that of the systems to the growth of algae during summer. Analysis of $BOD_5$ and SS concentrations in the final effluent of the systems shows that they meet the secondary treatment standards. The study demonstrates that wastewater treatment pond system which is similar in design to the systems can be reliably utilized at Kimpo, Korea. A model is proposed which can integrate a pond system with aquaculture and agriculture.

This study aimed to analyze the characteristic of the distribution of minimum temperature during January in the central region of South Korea and to investigate causes for the occurrence of extreme minimum temperature in Cheorwon. January temperature distribution data which were collected from 25 weather stations in central area from 1991 to 2010 were investigated, and the difference of temperature between Cheorwon and the other stations in central region, such as Chuncheon, Hongcheon, Bonghwa, Daegwallyoung, Wonju and Jecheon were analyzed by the type of atmospheric pressure system. Daily mean temperature and mean of daily minimum temperature appear to be low at Cheorwon and at the sites in high altitudes, but the frequency of extreme cold wave such as below $-15^{\circ}C$ is also noticeable in Cheorwon. When the Siberian High has expanded and migratory anticyclone has moved onto the north of the Korean Peninsula, the temperature at Cheorwon is relatively low. Furthermore it shows a lesser difference between Cheorwon and the compared stations when the migratory anticyclone affected the area, even at basin like Bonghwa, Jecheon more lower than Cheorwon.

This study was conducted to estimate genetic variation of Pinus densiflora in Kyungpook province which shows morphological variation between northern and southern types. Six isozymes sueh as IDH, ME, PGI, ADH, GOT and LAP was analyzed using megagametophyte tissue of seeds by electrophoresis and 16 populations of Pinus densiflora and 5 of Pinus thunbergii were tested. The results obtained were as follows ; 1. In P. densiflora, 13 Loci were found in 6 isozymes and 8 loci of them were polymorphic, having 24 alleles, while in Pinus thunbergii, there were 18 alleles detected from 6 loci among the same number of loci as in Pinus densiflora. 2. The genotypic frequency in Pinus densiflora vary slightly among populations for some isozymes, but most of them satisfied the law of Hardy-Weinherg equilibrium, while some populations such as Youngil for ADH and LAY, Youngyang for ADH and Bonghwa for LAY did not follow the law and showed high fixation index values and homozygosities higher than expected. 3. The variation among populations based on the genetic distance was small except populations of Youngju, Baegam, Gyungju and Sangju, however they could be clustered by three groups : northern Kyungpook group including Mt. Taebak, inland Kyungpook group represented by Sungju, Eusung and Kumleung population and coastal Kyungpook group represented by Baegam and Gyungju population. 4. No significant difference was found in 6 isozymes between northern and southern types of Pinus densiflora which was morphologically different. 5. The frequency of heterozygous loci per tree was higher in Pinus densiflora especially for ME-A and A DH-B, while that of homozygous loci was higher in Pinus thunbergii except for ADH-B, LAY-B and PGI-B locus.
