한말 신문광고를 유심히 살펴보면 최최의 전문적인 서적상이라 할 '대동서시'가 문을 연 1896년 이후부터 한일합방 때까지의 15년간, 경향 각지에 무려 70여곳의 서점이 있었던 것으로 확인된다. 이는 경술국치를 전후한 시기에 고작 10여개의 서점이 서울에서 영업을 하고 있었다는 지금까지의 통설을 크게 수정한다는 점에서 눈길을 끈다.

결혼하여 가정을 갖는다는 것은 사회적으로는 한 구성단위를 이루는 것이며 나아가서는 종족을 이어가는 것이다. 따라서 결혼은 인생에서 가장 중요한 일 중 하나이다. 나라마다 결혼 풍속은 다르다. 하지만 모든 사람이 신랑과 신부에게 축하하는 마음은 똑같고 두 사람이 사랑과 행복으로 가득한 가정을 이루기를 기원한다. 그동안 90개국을 두루 다니며 여행을 하는 동안에 지구촌의 흥미로운 결혼 모습을 여러 번 보았다. 경험했던 흥미로운 결혼 풍습을 소개한다.

고급단백질원인 축산물의 섭취가 경제성장과 더불어 삶의 여유가 생기면서 그 비중은 나날이 늘어가고 있다. 최근 well-being이란 말이 이제는 하나의 단어로 인식되고 있으며 삶의 양적인 측면 보다는 삶의 질을 우선시하는 풍속도가 널리 퍼지고 있어 특히 식생활에서 맛과 안전을 생각하는 경향이 뚜렷해지고 있다.(중략)

The long-span bridges such as Incheon Bridge and Seohae Grand Bridge are located on the coastal region effected frequently by strong wind of typhoons. In order to ensure the wind-resistant performance of the structure, estimation of the proper design wind speed is very important. In this study, stochastic estimation of design wind speed incurred by typhoons is carried out. For this purpose, we first established probability distribution of climatological parameters such as central pressure depth, distance of closest approach, translation speed and heading to build statistical model of typhoons, which are employed in Monte Carlo simulation for hypothetical typhoons. Once a typhoon is generated with statistically justified parameters, wind speeds are estimated along its path using wind field model. Thousands of typhoons are generated and their peak wind speeds are utilized to establish the extreme wind speeds for different return period. The results are compared with design basic wind speeds in Korean Highway Bridge Design Code, showing that the present results agree well with similar studies while the existing code suggests higher design wind speed.

In this study, detailed air flow characteristics in an urban areas were analyzed using GIS data and a Computational Fluid Dynamics (CFD) model. For this, a building construction algorithm optimized for Geographic Information System (GIS) data with a vector format (Los Angeles region imagery acquisition consortium 2 geographic information system, LARIAC2 GIS) was used. In the LARIAC2 GIS data, building vertices were expressed as latitude and longitude. Using the model buildings constructed by the algorithm as the surface boundary data in the CFD model, we performed numerical simulations for two building-congested areas in Los Angeles using inflow information provided by California Air Resources Board. Comparing with the inflow, there was a marked difference in wind speed and direction within the target areas, which was mainly caused by the secondarily induced local circulations such as street-canyon vortices, horse-shoe vortices, and recirculation zones. In street canyons parallel to the inflow direction, wind speed increased due to a channeling effect and, in street canyons perpendicular to the inflow direction, vertically well developed vortices were induced. In front of a building, a horse-shoe vortex was developed near the surface and, behind a building, a recirculation zone was developed. Near the surface in the areas where the secondarily induced local circulations, wind speed remarkably increased. Overall, wind direction little (largely) changed at the areas where wind speed largely increased (decreased).

In order to provide an information as input data of possible storm surges in advance, the typhoon center and maximum wind position analysis scheme must be developed for the initialization of pressure and wind field.This study proposes a semi-automatical and objective analysis method and a procedure on a real time basis using the satellite TBB data of the GMS IR1, NOAA satellite CH4 and CH5, and shows the result of an experimental analysis. It includes a simple method of determining the parameters of the typhoon using minimum top temperature of the convective cloud near the inner eyewall. The method analyzing the isotropic cross sectional variation of TBB gradient from center to environment was developed to determine the center of Rmax of typhoon. This position of intense eyewall from typhoon center can be considered as the position of maximum wind. The results of estimation of typhoon center show very good agreement to the results of synoptic analysis. It is found that the Rmax is approximately 50-200km. From the comparison of the GMS and NOAA IR TBB data, it is found that the Rmax from NOAA data tends to be longer than those from GMS data.

The amount of evapotranspiration (water absorption) according to wind speed showed the same trend in gold mound (Spiraea × bumalda), Japanese spurge (Pachysandra terminalis), and ivy (Hedera japonica Tobler). All the three plants showed maximum water absorption at 4 m·s-1; water absorption tended to decrease as wind speed decreased. The control group without wind speed treatment had the most amount of water absorption compared with the groups that were subjected to wind exposure. However, the plant growth of all three plants increased to the maximum value when wind speeds were 2 and 1 m·s-1. When comparing the relationship among water absorption, air temperature, and relative humidity, the water absorption of plants tended to be low from May 20 to 26, when air temperature and relative humidity were the lowest. The results of this study will help establish an urban wall-planting system taking building wind into consideration. Further, this study may help in the selection of plant types for ecological parks in windy islands.

This study investigated the effects of the urban forest and street trees on flow and temperature distribution in the Daegu National Debt Redemption Movement Memorial Park. For this, we implemented tree-drag and tree-cooling parameterization schemes in a computational fluid dynamics (CFD) model and validated the simulated wind speeds, wind directions, and air temperatures against the measured ones. We used the wind speeds, wind directions, air temperatures predicted by the local data assimilation and prediction system (LDAPS) as the inflow boundary conditions. To investigate the flow and thermal characteristics in the presence of trees in the target area, we conducted numerical experiments in the absence and presence of trees. In the absence of trees, strong winds and monotonous flows were formed inside the park, because there were no obstacles inducing friction. The temperature was inversely proportional to the wind speed. In the presence of trees, the wind speeds(temperatures) were reduced by more than 40 (5)% inside the park with a high planting density due to the tree drag (cooling) effect, and those also affected the wind speeds and temperatures outside the park. Even near the roadside, the wind speeds and temperatures were generally reduced by the trees, but the wind speeds and air temperatures increased partly due to the change in the flow pattern caused by tree drag.
