  • The main objective of this study was to investigate the pattern of glucosinolates, in terms of 3-butenyl isothiocyanate, and total glucosinolates, in different parts of young seedlings and seeds in Korean Chinese cabbages. For determination of glucosinolates, 55 days and Winter pride cultivars of Korean Chinese cabbages seeds and different parts of 1, 3, 5, and 7-day-old seedlings were used for analytical sample preparation provided with an anion exchanges column, and measured by GC and UV-visible Spectrophotometer. The concentration of 3-butenyl ITC was higher in the cotyledon and the hypocotyl parts of 55 days cultivar seedling than those of Winter Pride cultivar. In the cotyledon parts of Winter pride cultivar seedling, 3-butenyl ITC amount was increase to 3-day-old seedling and then reduced. The cotyledon of 55 days cultivar contained the highest concentration of total glucosinolates while those were increased in the hypocotyl and decreased in the root. The level of total glucosinolates was increased to 5-day-old seedling and then decreased in the cotyledon and the hypocotyl parts of seedling in Winter pride cultivar. There was no significant difference of total glucosinolates in the root part. In the seeds, 55 days cultivar concentration was higher than Winter pride cultivar both of 3-butenyl ITC and total glucosinolates. In our study, the levels of 3-butenyl ITC and total glucosinolates depended on cultivars, growth stages, and parts in Korean Chinese cabbage.

  • As a new type of healthy public space, greenway users carry out leisure activities, exercise, sightseeing and necessary transportation in greenway. However, at present, there is little research on greenway users' evaluation and perception of greenway, and there is no comprehensive exploration of Greenway environment from a humanistic perspective. Combined with the research and actual situation of the existing representative greenways in Chinese cities, this paper refers to a large number of documents, applies the semantic difference method and multiple regression analysis method, analyzes the current situation of the Dongfengqu greenway, explores the influencing factors and impact evaluation of the greenway environment from the perspective of greenway users' perception, and puts forward suggestions on the optimization of the greenway environment in Zhengzhou from multiple levels. The main conclusion of this paper comes from the data conclusion obtained by semantic difference method, which is feasible in the resident evaluation of greenway use. The feedback results of post use evaluation can provide a reliable reference for the planning and design of similar greenways in the future.

About a Wind-chime excavated from WolnamSaji(月南寺址) in GangJin (강진 월남사지(月南寺址) 출토 금동풍탁(金銅風鐸)에 대하여)

  • The Gangjin WolnamSaji(月南寺址) is a small site where three-story pagodas and a destroyed tombstone remained. In 1973, it was discovered that the destroyed tombstone was that of the second master of Susunsa, Hye shim(慧諶), who had a special relationship with the military regime in Goryeo, and it once again attracted attention as a result of the recent excavation of the Rooftile of Yeonhwamun(蓮花文). In particular, the Windchime excavated in 2012 is a large-sized one group with a length of 23cm, and a relatively large Sanskrit character was decorated on four sides of the body. In addition, it was also confirmed in preservation process that the word 'gaecheon(盖天)' was engraved. The Sanskrit characters(梵字) om( , oṃ), a( , a), hum( , hūṃ), brum( , bhrūṃ) were decorated on the body of the Wind-chime excavated in WolnamSaji. Om( , oṃ), a( , a), hum( , hūṃ) are known as the Sammiljineon(三密眞言) and brum( , bhrūṃ) has the meaning of having the highest honor. In addition, the Sammiljineon(三密眞言) allows us to understand the truth by responding to the principle of universe, which is the Vairocana Buddha(毘盧遮那佛), and brum( , bhrūṃ) has the meaning of unity. In the end, the meaning of the Sanskrit decorating the four sides of the Wind-chime, of WolnamSaji(月南寺址), can be interpreted as the expression of the Buddha's doctrine, or the willingness to be combined with Buddha, the highest existence in itself. It is possible that the word 'gaecheon(盖天)' carved on the body can be regarded as the name of the master craftsman related to the making of the Wind-chime, but it is unlikely that it is the name of the master craftsman, considering that it is a place where the location is not easily seen. If so, you can think of the original function that the Wind-chime has. In other words, it can be interpreted symbolically and implicitly that the wish of the sound of the airwaves symbolized by the words of the Buddha covers the sky and spreads all over the place. It is thought that the Wind-chime excavated in WolnamSaji(月南寺址) was made in the mid to late 13th century considering the comparisons with another wind-chime excavated from the temple site, the historical situation in the late Goryeo, the publication date of the scriptures(經典) of Esoteric Buddhism(密敎).

  • Due to the temporal and spatial variability of the warming at and near the Antarctic Peninsular, it is required to better understand local climate at the issued region. The purpose of the study are to characterize surface radiation, air temperature and wind direction and investigate their relations at the King Sejong Station near the Antarctic Peninsular during last three and half years. While the study site was a weak radiative energy sink (positive net radiation) with annual mean of 15-20 Wm-2, it played a role as a strong sink in summer (December to January) with mean of 85 Wm-2, a magnitude that was significantly larger than those at other surface covered with snow or ice in Antarctica. Monthly averaged air temperature ranged from -7.7-2.8oC and the variations of monthly averaged air temperature showed the distinct differences with year. Northwesterly, westerly and easterly were dominant and the variability of air temperature could be explained by the variability of the frequency of wind direction with cold easterly and warm northwesterly/northerly to some degree, which in turn influenced radiation budget through albedo in summer.

  • In this study, the observation environment of surface wind at an automatic weather station (AWS 288) located at Naei-dong, Mirang-si was analyzed using a computational fluid dynamics (CFD) model and geographic information system (GIS). The 16 cases with different inflow directions were considered before and after construction of an apartment complex around the AWS 288. For three inflow directions (south-south-westerly, south-south-easterly, and north-north-westerly), flow characteristics around the AWS 288 were investigated in detail, focusing on the changes in wind speed and direction at the AWS location. There was marked difference in wind speed between before and after construction of the apartment complex in the south-south-westerly case. In the south-south-easterly and north-north-westerly cases which were frequently observed at the AWS 288, the construction of the apartment complex had no marked influence on the observation of surface wind.

  • Heavy snowfall events frequently occur in the Gangwon province, and the snowfall amount significantly varies in space due to the complex terrain and topographical modulation of precipitation. Understanding the spatial characteristics of heavy snowfall and its prediction is particularly challenging during snowfall events in the easterly winds. The easterly wind produces a significantly different atmospheric condition. Hence, it brings different precipitation characteristics. In this study, we have investigated the microphysical characteristics of snowfall in the windward and leeward sides of the Taebaek mountain range in the easterly condition. The two snowfall events are selected in the easterly, and the snow particles size distributions (SSD) are observed in the four sites (two windward and two leeward sites) by the PARSIVEL distrometers. We compared the characteristic parameters of SSDs that come from leeward sites to that of windward sites. The results show that SSDs of windward sites have a relatively wide distribution with many small snow particles compared to those of leeward sites. This characteristic is clearly shown by the larger characteristic number concentration and characteristic diameter in the windward sites. Snowfall rate and ice water content of windward also are larger than those of leeward sites. The results indicate that a new generation of snowfall particles is dominant in the windward sites which is likely due to the orographic lifting. In addition, the windward sites show heavy aggregation particles by nearby zero ground temperature that is likely driven by the wet and warm condition near the ocean.
