Based on the land system of Joseon Dynasty and contemporary perception of land, this study analyzed the reason Yun seon-do entered Bogildo Island and a characteristic of Buyong-dong garden. According to this analysis, this study interpreted the purpose that Yun seon-do had built Buyong-dong garden at a socio-economic perspective. The land such as Sarlimchontack(山林川澤) is recognized as a commonland in the Joseon Dynasty. Except the reserved area(禁山), however, actions to make commonland private through Ib-an(立案) and protecting graves was frequent. Bogildo Island was a place difficult to build a private garden because the island had been appointed a reserved forest to protect pine trees. Right after Byungjahoran, Yun seon-do entered the island on the pretext of protecting forests, and built Buyong-dong garden. The island was easy to move to manage private farms as well as possessed abundant forest resources and resources that have economic value such as fish and salt. It indicates that, unlike his pretext, economic benefits have also been considered.

There isn't much of discussion about survey of traditional Korean garden with a perspective of Pungsu. Strictly speaking, it is difficult to list the names of gardens in which Pungsu theory is applied. But it is necessary to study in depth the Korean garden in mountain in relation with Pungsu. The reason is as follow; First, Pung-su and gardening both reflect man's responsive attitude and approach toward nature. Second, selecting a site for a garden requires aesthetic eyes to consider the harmony with the surrounding landscape and its compositions, where the perspective of Pungsu can play as an important component at work. Third, Pungsus complementary function justifies the correlation between Pungsu and Korean gardens. Gardens can be viewed as a solution to complement negative elements of Pungsu on site. This article tries to study the relationship between Pungsu and Korean garden in mountain in terms of Pungsu aesthetics. In Kosan Yoon Sun-Do's Buyong-dong garden, excavated perspectives of Pungsu aesthetics are fell into two categories; the spatial frame based on Pungsu topography and the dimension of enjoyment through visual angles between essential points. The former can be said as Pungsu topography as a mental image which was constructed by selected points and given Pungsu meanings; the latter is visual angles between those points by which make it possible to see and enjoy in comfortable sights. In such way making and enjoying Buyong-dong garden with full of Pungsu oriented meanings and aesthetics, Kosan Yoon Sun-Do enjoyed and sublimated his experience in nature into art.

When we put a construction on the space organization form of Seyeon-jong garden through a consequence of drawing analysis, we were able to certify that a certain space construction principle was applied as following. First, the arrangement and organization of space construction element embodied systematic order y clearing the character of space, and heightening the degree of cognizance with the means of functionability, scale, height, decorationability, an inclination of artificiality and nature, systemetic approchability. Second, the space construction element of Seyeon-jong garden pursued a harmony of human work and nature for creating a various atmosphere and visual quality. Third, Seyeon-jong garden constructed the space by establishing the measurement of human scale that introduced a conception of near, middle, distant view on the visual angle. Forth, Yun go san introduced the natural shape of 'The song of five friends' as a construction element, and represented the symbolism that he had seeked for throught he arrangement method, christening, composing technique of the space construction element for expressing ideal space which is described in 'The four season song of fishermen' spatially at Seyeon-jong garden. As the results of this study, that Yun go san created his own ideal space that he longed for at Seyeon-jong garden with applying fixed design system, and he realized his will that he strived to form a complete whole in perfect harmony.

부산의 대표적 큰 계곡인 성지곡수원지는 남쪽으로 부산의 최대 도심인 서면을 향해 열려 있고, 그 이외의 삼면은 높은 산지로 둘러싸여 있다. 그래서 성지곡-서면-남항 일대는 낮에는 해풍이 곡풍(남풍)의 형태로 불고, 야간에는 산풍이 육풍(북풍)의 형태로 불고 있다. 이렇게 형성된 국지풍 순환의 규모와 특성을 평가하기 위하여, 계곡 입구와 도심인 서면 부근에 자동기상관측장치를 설치하여 특별 관측을 수행하였다. 관측결과 주간에는 서면 부근의 기온이 성지곡 입구보다 낮았고, 야간에는 이와 반대로 나타났으며 그 차이는 대체로 $3^{\circ}C$ 내외였다. 이것은 주로 지표면 가열의 의한 기단변질의 결과로 판단된다. 관측 일에 확인된 도로표면온도는 낮에 약 65도까지 상승하였으며 야간에도 30도 정도의 고온이 유지되었다. 이 연구에서는 현장관측으로 확인된 기단변질과정을 이해하기 위하여 2차원 대류모델을 이용한 수치실험을 수행하였다. 수치실험의 결과 낮에는 지표로부터 약 $150W/m^2$이상의 현열이 보급됨이 확인되었다. 야간에도 $10W/m^2$ 내외의 현열이 대기 중으로 보급되어 성지곡 수원지에서 발원된 냉기류를 가열시키고 있음이 확인되었다.

대구와 추풍령이 겨울철(2005년 12월${\sim}$2006년 2월)과 여름철(2006년 6월${\sim}$8월) 시간대별 일 최고기온, 일 최저기온, 일 평균기온과 풍속자료를 사용하였다. 추풍력은 대구에 인접해 있으면서 도시화의 영향을 상대적으로 매우 적게 받은 지역이다. 대상일은 대구와 추풍령의 겨울철과 여름철을 대상으로 일 최고기온과 다음날의 일 최저기온간의 차이가 $10^{\circ}C$이상인 날을 선정하고, 그 중에서 운량이 30%이하인 맑은 날을 선정하였다. 그리고 선정일을 대상으로 도심과 교외지역 야간(익일 18시${\sim}$다음날 06시까지)의 기온 냉각율을 조사한 결과는 다음과 같다. 기온하강은 두 지점 모두 풍속의 영향을 받음을 알 수 있었고, 또한 도시구조물이 많은 대구(도심)의 경우는 풍속이 강하더라도 건물에 의한 축열과 복사냉각의 억제에 기인하는 것으로 판단된다. 00시까지는 풍속과 냉각율이 비례하며 현열수송으로 냉각되고, 그 이후부터 일출까지는 풍속과 냉각율이 반비례하여 현열수송에 의한 가열의 경향을 확인할 수 있었다.

Interpretation of relevance between long-wave radiation and meteorological elements is recognized as an essential element for understanding the underlying mechanism of urban thermal environment formation. In this study, we analyzed relation between three elements : long-wave radiation, temperature, and lower-middle class cloudiness. The correlation was analyzed through field observations. The results are as follows. (1) Temperatures and long-wave radiation increased from January to March. This phenomenon has been confirmed in urban and suburban areas. (2) Long-wave radiations showed a tendency to increase clearly with increasing cloudiness.

This study was performed to observe the microhardness change of the surface and the bonding strength between the porcelain and alloy specimens in order to investigate the effects of appended indium, tin and copper on interfacial properties of Au-Pd-Ag alloys. The hardness of castings was measured with a micro-Vicker's hardness tester. The interfacial shear bonding strength between alloy specimen and fused porcelain was measured with a mechanical testing system(MTS 858.20). The microhardness of Au-Pd-Ag alloy was increased by adding indium and tin, but not increased by adding copper. The shear bonding strength of Au-Pd-Ag-Sn alloy and Au-Pd-Ag-Cu alloy showed 87MPa, 57MPa. The higher concentration of adding elements showed the higher shear bonding strength.

The temporal variations of methene emission and its relation to air temperature were investigated in Upo-swamp during June 2007 through July 2008. To perform this study, the methene emission and air temperature were observed using the buoy-type chamber and automatic weather observation system(AWS), respectively. The methene emissions were much during summertime(June~August). The maximum value(about 73.4 mg/$m^2$/hr) appeared at August. The emission diminished by degrees after August. The methene emissions were fewer from September to May of the following year. The peak value(73.4 mg/$m^2$/hr) of the methene emission is very much compared to that of rice pappy field known as about 28.7 mg/$m^2$/hr.

Many people have been building HTML documents due to rapid spread and growth of web. However, HTML has limits in satisfying user's requirements, so that XML has emerged. In this paper, we design and implement student information management programs and presentation methods for maintaing the general student life archives and the analysis of results of examinations using XML and web browser. We define a XML DTD for general student life archives, and build XML documents. A private student life archive is printed from XML documents on the web using XMLDOM, DATA-BINDING, and XSL. Also, personal items and a roll book of a class can be printed and searched. In order to analyze the result of examinations we define DTD and build XML documents according to the DTD.
