In this study, the observational environment for sunshine duration at Seoul and Daegu Automated Synoptic Observing Systems (ASOSs) was analyzed using a numerical model. In order to analyze the effects of topography and buildings on observational environment for sunshine duration, the model domains including the elevated building and mountainous areas around Seoul and Daegu ASOSs were considered. Three dimensional topography and buildings used as input data for the numerical model were constructed using a geographic information system (GIS) data. Solar azimuth and altitude angles calculated for the analysis period (one-week for each season in 2008) in this study were validated against those by Korea Astronomy and Space Science Institute (KASI). The starting and ending times of sunshine duration observed at ASOSs largely differed from the respective sunrise and sunset times simply calculated using solar angles and information of ASOSs' latitude and longitude, because uneven topography and elevated buildings around ASOSs cut off sunshine duration right after the sunrise and right before the sunset. The model produced the sunshine indices for Seoul and Daegu ASOSs with the time interval of one minute and the period of one week for each season and we compared the hourly averaged indices with those observed at the ASOSs. One week of which the cloudiness is lowest for each season is selected for analysis. Not only the adjacent buildings but also distant buildings and mountain cut off sunshine duration right after the sunrise and right before the sunset. The buildings and topography cutting off sunshine duration were found for each analyzing date. It was suggested that, in order to evaluate the observational environment for sunshine duration, we need to consider even the information of topography and/or building far away from ASOSs. This study also showed that the analyzing method considering the GIS data is very useful for evaluation of observational environment for sunshine duration.

Due to recent urban maintenance project for the aged towns, the reconstruction of apartments into super-high-rise and high-rise apartment structures has been approved for concentrated use of land, and accordingly the infringement on sunshine for nearby residential area is rising as a social issue. Especially the educational environment conditions according to infringement on sunshine in educational facilities are posing many problems. Accordingly in this study, for such sunshine analysis of educational environment, Auto $CAD^{(R)}$ software has been used to construct the 3D model for the educational facility structures. And with the simulation technique, the windows and the schoolyard of the education facility were set to be the lighting standard surface to take measurements for the sunshine environment of the educational facilities by the minute from 8:00AM until 4:00PM for the sunshine amount by true solar time according to the movement of the sun. Also, the sunshine environment of the education facility according to the damage before/after new construction of apartments was charted, and through comparison with the video produced by sun shadow projection method, the sunshine amount of the educational environment could be verified. In future, it is expected to be efficiently used in the sunshine analysis of education environment utilizing such simulation techniques.

This paper presents the results of a case study of a dispute for the damage of the right to sunshine between B and W Apartment Complex in the N city. Recently a number of disputes for the right to sunshine increase in urban areas because the residents' demand for pleasant residential environment is getting stronger. In particular, problems related to sunshine, which were not recognized during the construction, have come up to the surface over time as people's concern over residential environment is growing. According to a recent interpretation of the right to sunshine in urban areas, moreover, there have been a series of legal decisions starting that damage of the right to sunshine to neighboring apartments must be indemnified for even if the violating apartment was designed and constructed legitimately according to relevant construction laws applied when the building was constructed. Thus this study examined the effects and the scope of damage on the right to sunshine through a case study in order to provide basic materials necessary to rope with related civil affairs.

The "Tai Su(太素)" which was published by Yang Shang Shan(楊上善) during the Tang(唐) dynasty does not follow complicating hand down procedures allowing it to be preserved in a relatively satisfactory state, and the book is evaluated as a major article in the study of the "Yellow Emperor's Internal Classic(黃帝內經)" in the modern age. The book of "Tai Su explanation of channel diseases(太素 經脈病解)" offers the detailed description of disease symptoms found in the book of "Miraculous Pivot channels(靈樞 經脈)", and Yang Shang Shan(楊上善) provided relatively complete explanations from the perspective of the wane and wax of shadow and sunshine powers(陰陽消長). The present writing was projected to acknowledge the relationship between the books of "Tai Su explanation of channel diseases(太素 經脈病解)" and "Miraculous Pivot channels(靈樞 經脈)" and substantially attempted to understand the original text of the "Tai Su(太素)" by adopting the perspectives of Yang Shang Shan(楊上善) in explaining the disease symptoms as he attempted in the book of "Miraculous Pivot channels(靈樞 經脈)". Total 50 disease symptoms were explained in the book of "Tai Su explanation of channel diseases(太素 經脈病解)", and 33 of them are common to the symptoms described in the book of "Miraculous Pivot channels(靈樞 經脈)" by taking up about 66% of the book. The monthly attachment(月別配屬) of three shadow and three sunshine power(三陰三陽), which is described in the book of "Tai Su explanation of channel diseases(太素 經脈病解)" provides an important clue in understanding the exterior and interior(表裏) relationship, and the crucial perspective lies on the mutual intensity change of shadow and sunshine powers. Therefore, the monthly attachment of three shadow and three sunshine power provided by the present article helps to understand the meaning of the three shadow and three sunshine power along with the time attachment(時間配屬) described in the other chapter of the "Yellow Emperor's Internal Classic(黃帝內經)". In the method of explaining pathogenesis, the explanation was made by understanding the perspective of mutual intensity change of shadow and sunshine powers, and exterior and interior relationship along with the channel Path(經脈流注) have been used simultaneously. In the comment of the main article, Yang Shang Shan(楊上善) stated the channels of hands and feet(手足經脈) as the scope of the three shadow and three sunshine power, but the symptoms and signs are mainly focused on the channels of feet as in the book of "Miraculous Pivot channels(靈樞 經脈)".

Recently, distribution transfer velocity was extremely lowered by high supply rate of vehicle and low road rate. Therefore expansions of transfer network these were subway, road and railway to recover competitive power as a reform measure of physical distribution traffic were become preference previous subject. For reason of that, an expansion of transfer network is meeting competitive power as selected an elevated road in the ground road network that condition of location calm and get out of the existing urban than the underground road to connect oversensitive a large city and expanded small and medium satellite town. In the meantime, while elevated structures construct, they go through the civilian residential section, agriculture land, etc. The consequence is that it raises a vibration, noise, dust, an infringement of the right to a view and an infringement of the right to a sunshine. In this study, we analyzed Quantitatively sunshine quantity with building 3D simulation model of civil structure. Therefore, we present as planning data to reduce a civilian appeal for dispute of the right to sunshine and an economic and time loss between the government and construction company In addition to that, for the standard of the standard plan of usable sunshine quantity program in the practical business, the building of convenient user interface will be the project to be done.

This study was conducted to determine the time and methods of predicting tobacco yield. by analysis of climatic factors in the period of tobacco season during 8 years from 1979 to 1986 at the Daegu district, south eastern part of Korean peninsular. The results obtained are summarised as follows: 1. Climatic factors of each month which have influence on tobacco yield were the amount of rainfall in May and sunshine hours in July. Among climatic factors at tobacco growth stages, the precipitation yield. But these meteorological factors had different effect on variety. 2. Between tobacco yields and climatic factors by even values of each month, tobacco yield was estimated by equations, flue cured tobacco :Y=190.6-5.230X1+ 0.474$\times$2 + 0.142X3(Xl : Minimum temperature of April, X2: Precipitation during May, X3:Sunshine duration on July), air cured tobacco : Y= 195.3-0.447Xl + 0.363$\times$2 + 0.l12$\times$3(Xl :Maximum temperature of May, X2:Precipitation during May. X3: Sunshine duration on July). While between tobacco yield and climatic factors at different growth stage, predicting equation of yield could be derived, flue cured tobacco : Y=205.8+0.510Xl +0.289$\times$2 + 0.305$\times$3 (Xl :Average temperature during the early growth stage, X2 :Precipitation during the early and maximum growth stage, X3 : Sunshine hours during the leaf and tips maturing stage), air cured tobacco Y=194.T-0.498Xl 10.615$\times$2+0.121$\times$3(Xl ;Maximum temperature during the transplanting time, X2 : Precipitation during the maximum growth stage, X3 : Sunshine hours during the leaf and tips maturing stage).
