This study was undertaken the effect of high temperature and high humidity on protein expression and especially plasma membrane (PM) $H^{+}ATPase$ of umbel with flowers of early cultivar 'Shinsunhwang' and intermediate cultivar 'Maebsihwang' of onion (Allium cepa L.). There were no visible any difference on the protein pattern from before flowering stage to full flowering stage of two onion cultivars, however, seed set stages were revealed induced/deduced protein patterns. At day 18, protein expression pattern of the high temperature and high humidity treatments of two cultivars was significantly reduced compared to controls. Furthermore, various protein expression of the high temperature treatment was more reduced compared to high humidity treatment. PM $H^{+}ATPase$ expression of the control plants of two onion cultivars was clearly shown, but was not detectable under high temperature treatment of the two onion cultivars using western blot analysis. PM $H^{+}ATPase$ expression of the high humidity treatment was faintly detected intermediate cultivar 'Maebsihwang', not early cultivar 'Shinsunhwang'. These results indicate that protein expression pattern and PM $H^{+}ATPase$ under high temperature treatment was considered to be more damaged compared to high humidity.

기존 도로시설을 최대로 이용하고 교통의 흐름을 질적으로 향상시키기 위해서는 과포화 상태를 고려한 교통시설운영방법을 개선할 필요가 있다. 속도-교통량관계는 교통시설운영의 평가와 서비스수준 산정을 위한 주요 판단기준이 된다. 본 논문에서는 경부고속도로 종점부 구간의 현장조사를 통해 과포화상태의 속도-교통량 관계를 조사 분석하였고 그 결과 다음 몇 가지 결론을 얻을 수 있었다. 첫째, 한국도로용량편람을 비롯한 우리 나라 연구결과는 일반적으로 50km/hr 일 때 용량상태가 나타난다고 알려져 있으나 본 조사결과에 의하면 약 85km/hr 정도에서 용량상태가 발생함을 관측할 수 있었다. 둘째, 과포화구간에서 속도에 따른 통과교통량 증감추이는 대기행렬 증가시 급격한 속도-교통량의 감소가 있는 반면에 대기행렬해소시 속도-교통량의 증가는 완만하게 회복됨을 보였다. 셋째, Ontario 고속도로의 경우와 본 조사연구결과는 비교해본 결과 과포화시 한국의 경우 미국과 동일한 통행속도에서 더 많은 교통량이 통행하는 것으로 확인되었다.

The Chisulryoung Volcanic Formation comprises a thick sequence of pyroclastic flow deposits. Six members are distinguished, each representing separate flow units, comprising weakly to intensely welded acidic tuffs. A stock of welded acidic tuff, 1 km in diameter, intrudes hornblende granodiorite and sediments of Late Cretaceous age and the lower part of the Chisulryoung Volcanic Tuff Formation and may represent the vent through which the upper flows of the Chisulryoug Volcanic Formation were erupted.

We studied the detailed bathymetry and the geophysical characteristics of the summit of the Dokdo volcano using mutibeam echosounding and geophysical survey data. The bathymetry around the main east and west islets of the Dokdo volcano shows very shallow within about 10 m water depth. From near islets to about 30 m b.s.l., the shallow water area has very steep slope and many irregular sunken rocks. The area from about 30 m to about 80 m b.s.l. shows gentle rises and falls, and less steep slope. The area from 80 m b.s.l. has gradually flat undulation and smooth slope seabaed and is extended to offshore. The main islets of the Dokdo volcano and the rocky sea bottom elongated from the islets might be the residual part of the eroded and collapsed main crater of the Dokdo volcano. The bathymetry and the seafloor image(from backscattering) data show small craters, assumed to be formed by the eruption of later volcanism. The seafloor images propose that, except some areas with shallow sand sedimentary deposits, there are typical rocky bottom such as rocky protrusions and lack of sediments in the main morphology of the survey area. The stepped slopes of the seabed are deduced to be submarine terraces. The several prominent submarine terraces are found at the summit of the Dokdo volcano, suggesting repetition of sea level changes(transgressions and regressions) in the Quaternary. The results of the magnetic anomaly and the analytic signal have a good coherence with other geophysical consequences regarding to the location of the residual crater.

Helicopter-borne aeromagnetic surveys at two different times separated by three years were conducted to better understand the shallow subsurface structure of the Vulcano and Lipari volcanic complex, Aeolian Islands, southern Italy, and also to monitor the volcanic activity of the area. As there was no meaningful difference between the two magnetic datasets to imply an apparent change of the volcanic activity, the datasets were merged to produce an aeromagnetic map with wider coverage than was given by a single dataset. Apparent magnetisation intensity mapping was applied to terrain-corrected magnetic anomalies, and showed local magnetisation highs in and around Fossa Cone, suggesting heterogeneity of the cone. Magnetic modelling was conducted for three of those magnetisation highs. Each model implied the presence of concealed volcanic products overlain by pyroclastic rocks from the Fossa crater. The model for the Fossa crater area suggests a buried trachytic lava flow on the southern edge of the present crater. The magnetic model at Forgia Vecchia suggests that phreatic cones can be interpreted as resulting from a concealed eruptive centre, with thick latitic lavas that fill up Fossa Caldera. However, the distribution of lavas seems to be limited to a smaller area than was expected from drilling results. This can be explained partly by alteration of the lavas by intense hydrothermal activity, as seen at geothermal areas close to Porto Levante. The magnetic model at the north-eastern Fossa Cone implies that thick lavas accumulated as another eruption centre in the early stage of the activity of Fossa. Recent geoelectric surveys showed high-resistivity zones in the areas of the last two magnetic models.

Topography and soil characteristics of earth hummocks are examined in the summit crater of Mt. Halla in order to evaluate their morphoclimatic significance as an indicator of a periglacial environment. The hummocks are generally oval in outline, and they have a diameter of 42 to 200 cm and a height of 9 to 27 cm Seventeen hummocks are distributed In a 5$\times$5 m quadrat at an interval of 20 to 40 cm Excavation reveals the cryoturbated soil profiles which consist of upper dark brown layer and lower brown layer. The dark brown layer has 61.8% total clay and silt content, implying Its high frost susceptibility Earth hummocks have the dry density of 0.761 to 1.009 g/㎤ the void ratio of 1420 to 2.008, and the moisture content of 24.2 to 68.8% by weight, respectively. The hummocky soils become compacted and desiccated downward. Earth hummocks are frozen as a hard solid mass during winter and early spring, and freezing fronts reach about 45 cm below their apices. The layer with high lute content appears in the upper horizon of dark brown soil. but Ice lenses are not so much segregated The moisture content of hummocky soils generally increases up to 73.9 to 118.80% for dark brown layer and 49.9 to 82.8% for brown layer during thins period Because the cohesive soil of earth hummocks indicates 72.8% of the moisture content as a liquid limit, the dark brown layer is highly fluid and consequently subject to cryoturbation processes.

A total of 95 broccoli (Brassica oleracea L. var. italica) accessions were evaluated for the identification of desulfo-glucosinolates and their content variation in the flower head using ultra performance liquid chromatography, to select the potentially functional broccoli breeding lines. The six individual desulfo-glucosinolates, including progoitrin, glucoraphanin, sinigrin, gluconapin, glucobrassicanapin, and glucobrassicin, were commonly identified, based on the chromatogram peak comparison with those of the nine individual glucosinolate standards. The total glucosinolate contents varied from 4.2 to $29.0{\mu}mol{\cdot}g^{-1}$ DW and the glucoraphanin (1.6 to $13.9{\mu}mol{\cdot}g^{-1}$ DW) was confirmed as a major constituent in the total glucosinolate profile among the six identified individual glucosinolate species, whereas the progoitrin, which was only detected in 13 accessions, showed accession-specific variation and negative correlation with glucoraphanin content. It was also revealed that the four major glucosinolates, such as glucobrassicanapin, glucoraphanin, glucobrassicin, and gluconapin, affected major content variation and showed higher positive inter-correlation. These results might be used for the selection of potential breeding materials as functional broccoli germplasm through the further evaluation on the stability and reproducibility of glucosinolate profile depending on environmental factors or cultural managements using the selected accessions.
