In this study, genus Cosmarium, 3 species, 2 varieties, 1 forma were sampled at 14 stations from August 1987 to July 1988. The character variations in populations were studied from the cultured plants. As a result, 1 species, 1 variety and 1 forma were treated as synonyms according to the polymorphism found at the same colony. C. angulosum f. rotundatum was different from C. angulosum by the front view, but C. angulosum type and C. angulosum f. rotundatum type occurred simultaneously in the same colony. C. angulosum f. rotundatum was included in C. angulosum which is type species. c. auriculatum, C. subauriculatum and C. subauriculatum var. truncatum have been sorted by the shape of cell and the number of granules at the lower sides of semicell. For three types occurred at the same colony, those species and variety treated as synonym of C. auriculatum which was named first.

Cosmarium candianum and C. obtusatum were sampled at 11 stations in Korea from October 1987 to June 1988. The samplings were cultured for study of the character variations in colonies. As a result, C. candianum var. candianum f. minutum, C. candianum var. depressum and C. candianum var. latius need not be separated from C. candianum, because 4 types in C. candianum complex occurred simultaneously in the same colony. It was changed the species reported as C. circulare Reinsch in Korea presently into C. candianum Delponte according to Compere's review. Because 2 types of C. obtusatum complex occurred at the same colony, C. obtusatum var. beanlandii need not separated from C. obtusatum.

It has been considered that genus Cosmarium including Staurastrum had the problems in grouping by morphological characters. Sequence data for the Cytochrome Oxidase subunit III (coxIII) were employed to compare with taxa of two divisions of this genus, with sections in each, for evaluating the taxonomic stability of these morphological characters. The division and section systems were not coincided with the phylogeny inferred from coxIII sequences, as the previous reports from us using nuclear rDNA ITS and chloroplast rbcL sequence comparisons in this genus. Two taxa of Staurastrum were not placed within a same clade each other, and one taxon of these was grouped in Arthrodesmus clade. Two genera, Cosmarium and Staurastrum, cannot be regarded as monophyletic from this result. Mitochondrial coxIII gene was considered as a useful phylogenetic tool to evaluate evolutionary relationships of desmids as in the case of land plants.

경기도 김포시의 변화가 예사롭지 않다. 한강신도시가 들어서면서 신흥 주거지로 명성을 높이더니, 이제 경인아라뱃 사업이 본격화됨에 따라 산업계의 시선 역시 집중시키고 있다. 경인아라뱃길 사업이 산업계의 주목을 받는 가장 큰 이유는 김포터미널(김포 고촌읍 전호리 일대)에 조성될 '김포물류단지' 때문이다. '김포물류단지'의 북측에는 마리나를 중심으로 관광, 레저 및 수변상업시설이 배치된다. 또 남측에는 컨테이너 부두와 연계한 장고 집송시설 등 물류시설이 들어선다. 가히 문화와 산업이 어우러진 수도권 서부지역 최대의 물류소통 전진기지가 등장하는 것이다. 이 전진기지의 중심에는 삼성에버랜드가 시공하고 있는 '수도권 통합물류센터' 가 있다. 이 센터는 연면적 $63,571m^2$의 물류창고로, 김포물류단지 내에서는 최대 규모를 자랑한다. 즉 김포물류단지를 대표하는 건축물인 셈이다. 때문에 삼성에버랜드는 큰 책임감과 자긍심을 갖고 시공에 임하고 있다. '철저한 안전관리' 로 김포물류단지의 랜드마크를 선보이겠다는 이곳 현장을 찾아가 봤다.

A natural ventilating type store was designed for the economic and effective storage of citrus fruits in Jejudo. The material used for the wall is scoria, widely distributed in Jejudo and known for high strength and insulation. Design condition was chosen for the period till March of a year and the dry bulb temperature was taken from TAC $5\%$ base. The temperature of the store can be maintained below the limiting temperature of $8^{\circ}C$ for the time length of $7\frac{1}{2}$ hours under the condition of the atmospheric temp, $15.3^{\circ}C$ and the solar insolation. The limiting temperature can he recovered to the initial temperature $(7^{\circ}C)$ by the natural ventilation for 8 hours in the night.

There have been always some difficulties in target setting and conditioning of acoustic performances of the Korean traditional music hall due mainly to the lack of the information on the sound radiation characteristics of Korean musical sources. In this study, the radiation characteristics of four typical Korean traditional musical sources were investigated in precision and their usage was demonstrated: The selected musical sources were Gayageum (string), Daegeum (woodwind), Jango (drum), and Pansori Chang (vocal performance). Each sound source was located at the center of a semi-anechoic chamber and the directivity was determined by the measured sound pressure levels in every 10° angular position, for both vertical and horizontal directions. The directivity pattern of Gayageum varies from a uniform to a complex pattern having many side lobes with the increase of frequency. The main radiation of Daegeum is toward the upward direction. The directivity pattern of Jango is clearly a side-oriented one and the left direction intensity is sharper than its right side at low frequencies. For the Chang, the directivity pattern change from a uniform pattern to a frontally directed one as the frequency goes high. Measured directional and spectral characteristics of traditional Korean music sources were implemented into the computation of architectural acoustic measures for the Busan National Korean Traditional Music Hall which is under construction. Parameters such as RT, SPL, C80, IE, STI were calculated at two receiver positions by using a ray tracing technique. Significant differences in the acoustic measures at receiver positions were observed between the results in using the omni-directional source and the directional one. It is thought that the suggested source data and design method can be used as a basic reference in the future acoustic design of performance halls for the Korean traditional music.

This study was conducted to investigate the effects of End-coating (CO) treatment and Vapor-dam (V) treatment on the air circulating oven drying characteristics of green stock (Paulownia tomentosa) for drum. The reduction of the weight of specimens was greatly displayed in order of control (C-NC) treatment, End-coating (C-CO) treatment, Vapor-dam (V-NC) treatment and Vapor-dam/End-coating (V-CO) treatment after the beginning of drying. The V-CO treated specimen showed smoother temperature gradient compared with the V-NC treated specimen throughout whole drying stage and there was little temperature gradient between the inner and outer part of the cylindrical stock. The C-CO treated specimen showed higher value of vapor pressure in both the inner and outer part of the cylindrical stock until the middle stage of drying, while after the middle stage of drying only the inner part of the cylindrical stock presented higher value compared with the C-NC treated specimen. The distribution of the absolute vapor pressure of the V-CO treated specimen was similar to that of the V-NC treated specimen during the initial stage of drying. However, the former showed a large distribution in order of the hollow, the outer part, the inner part of the cylindrical stock after the initial stage of drying, which was entirely different model of distribution from that of the V-NC treated specimen. Surface checks and ring failures were not observed for all of the specimens, while end checks were severely occurred for the C-NC treated specimen and the V-NC treated specimen.

This paper studies the restoration of Jeongeup notated in Daeakhubo to a singable song. Firstly, the melody of Jeongeup was restored by finding the rhythm of Jeongeup. Secondly, Jeongeup lyric written in Akhakgwebeom was added to the restored melody. Lastly, the musical style of restored Jeongeup song was investigated. The rhythm of Jeongeup was found to be the same as Jinjak's rhythm whose measure consists of four ternary subdivided beats. It is because the Jangdan of Jeongeup contains that of Jinjak. The Jangdan of Jeongeup is played one touch in a measure. Such ternary subdivided beat and one Janggo's touch in a measure were transmitted to today's Sujecheon. The lyric of Jeongeup was added to the restored melody of Jeongeup by following the lyric rules of Jinjak1,2 and Hoengsalmun. The lyric rules of Jinjak 1,2 and Hoengsalmun are as follows. One syllable is sung in two measures, Eodanseongjang 語短聲長 appears, long lasting tunes are mostly applied to Jang of Eodanseongjang 語短聲長, and syllables begin at the first beat in a measure. The musical style of Jeongeup is basically similar to that of Jinjak1, but there are some differences. They are similar in the sense that the melody is very long compared to the lyric and Eodanseongjang 語短聲長 appears. They are different in the sense that Jeongeup uses grace notes rather than Sigimsae when one tune lasts long. Jeongeup in Daeakhubo seems to have undergone changes, and its rhythm is likely to have been expanded two to four times in order to match Mugo dance after being used as an accompaniment to Mugo dance.
