  • The followings are concluded from the treatment of headache in Hyungsang medicine, focussed on 11 kinds of headaches in Donguibogam. Headache is classified into overall headache and migraine according to the affected region. The causes are divided into exogenous affection and internal injury; The former brings on headache due to Wind-Cold and headache due to Damp-Heat. The latter, reversal headache, headache due to adverse rising of phlegm, headache due to regurgitation of Gi, headache due to excessive Heat, headache due to excessive Damp, true headache, and alcoholic headache. Headache due to internal injury generally tends to show deficiency syndrome with external affection. Headache due to exogenous affections is common to those who have big head or white skin and to Bangkwang type, and woman. The primary causes are Wind-Cold and Wind-Heat. When the body is observed in the perspective of eight phases, Damp-Heat is to be produced in the front, and Dry-Damp, in the back. Headache due to Damp-Heat is susceptible to Yangmyeong meridian type whose body develops more in the front and to woman. In the perspective of the upper and the lower, Yangdu(that is, head) is related to Eumdu(that is, glans of penis). Headache is also caused by the problems of Eumdu ,such as deficiency of Essence in man, pathologic change of uterus in women, and San syndrome in lower abdomen. In the case of man, headache is frequently severe and difficult to treat because head is a root for man. Disharmony of Gi and blood between the right and the left brings out migraine and headache due to regurgitation of Gi. Migraine is usually accompanied by symptoms of exogenous affection and often afflicts Gi-type, Shin-type, Soyang meridian type, deer type, and Dam-type. Headache due to regurgitation of Gi is brought by Gi deficiency or blood deficiency so that symptoms of exogenous affection do not show. It is mainly common with old people and those who have sunken eyes induced by deficiency of stomach Gi. In the perspective of the upper, the middle, and the lower, the pathologic change of head, chest and abdomen also bring about headache. The pathologic cause of head is Wind-Heat ,which triggers overall headache, migraine, headache due to Wind-Cold, headache due to excessive Heat, The pathogen of chest is phlegm-Fire and brings out headache due to Damp-Heat and headache due to adverse rising of phlegm. The pathologic factor in abdomen is Cold-Damp and produces headache due to adverse rising of phlegm and headache due to excessive Damp. In case of women, headache is generally caused by phlegm-Fire and retention of undigested food.

  • Recently, as a plan to improve the particulate matter and thermal environment in the city, urban forests acting as wind ventilation corridor(wind ventilation forest) are promoted nationwide. This study analyzed the conditions for the creation of wind ventilation forest(vulnerable areas of the particulate matter and thermal environment, distribution of wind ventilation forest, characteristics of ventilation corridor) of in Pyeongtae-si, one of the target cities of wind ventilation forest project. Based on the results, the direction of developing on the wind ventilation forest in Pyeongtaek-si was suggested. As a result of deriving areas vulnerable to particulate matter and thermal environment, it was most vulnerable in urban areas in the eastern area of Pyeongtaek-si. Especially, emissions were high from industrial complexes and roads such as the Pyeongtaek-si thermal power plant, ports, and the national road no. 1. The wind ventilation forest in Pyeongtaek-si was distributed with small-scale windgenerating forests, wind-spreading forests, and wind-connection forests fragmented and disconnected. The characteristic of the overall wind ventilation corridor in Pyeongtaek-si is that the cold air generated from Mt.Mubong, etc., strongly flowed into Pyeongtaek-si and flowed in the northwest direction. Therefore, it is necessary to preserve and expand the wind-generating forests in Pyeongtaek-si in the long term, and it was important to create wind-spreading forests and wind-connection forests so that cold air could flow into the vulnerable area. In addition, in industrial complexes and roads where particulate matter is generated, planting techniques should be applied to prevent the spread of particulate matte to surrounding areas by creating wind-spreading forests considering the particulate matter blocking. This study can be used not only as the basis data for wind ventilation forest project in Pyeongtaek-si, but also as the basis data for urban forest creation and management.

  • In this paper South Africa is divided into strong wind climate zones, which indicate the main sources of annual maximum wind gusts. By the analysis of wind gust data of 94 weather stations, which had continuous climate time series of 10 years or longer, six sources, or strong-wind producing mechanisms, could be identified and zoned accordingly. The two primary causes of strong wind gusts are thunderstorm activity and extratropical low pressure systems, which are associated with the passage of cold fronts over the southern African subcontinent. Over the eastern and central interior of South Africa annual maximum wind gusts are usually caused by thunderstorm gust fronts during summer, while in the western and southern interior extratropical cyclones play the most dominant role. Along the coast and adjacent interior annual extreme gusts are usually caused by extratropical cyclones. Four secondary sources of strong winds are the ridging of the quasi-stationary Atlantic and Indian Ocean high pressure systems over the subcontinent, surface troughs to the west in the interior with strong ridging from the east, convergence from the interior towards isolated low pressure systems or deep coastal low pressure systems, and deep surface troughs on the West Coast.

  • We have examined the influence of local wind on occurrence of fog at two inland areas, Chuncheon and Andong, in Korea. The surrounding topography of two inland areas shows significant difference: Chuncheon is located in the basin surrounded by ridges with north-south axis while Andong is located in the valley between the ridges with east-west axis. Occurrence of fog shows maximum in October at both sites but high occurrence of fog at Chuncheon is also noted in the winter. Occurrence of fog at Andong in October is much larger than that at Chuncheon. High occurrence of fog in October is due to favorable synoptic condition for fog formation such as weak wind, clear day and small depression of the dew-point. Fog occurrence at Chuncheon is closely related to very weak wind condition where wind speed is less than $0.5m\;s^{-1}$. The weak wind at Chuncheon in winter is due that pressure driven channeling wind (southerly) cancels out partly downslope northerly flow during nighttime. On the other hand, fog at Andong occurs well when wind is southeasterly which is thermally forced flow during nighttime. Southeasterly provides cold, moist air from the narrow valley to Andong during nighttime, leading to favorable condition for formation of fog.

  • For four calender years (1971-1974), daily observations of weather conditions (air temperature, humidity, wind speed, wind direction, cloud amount, fog, precipitation etc.) at six stations in the north western Pacific Ocean are used to calculate mean monthly values and to check extra-conditions. At Petropavlosk and Miko'skoe, where indicate the characteristics of modified continental climate, the temperature and humidity are high in summer, and Iow in winter. At A Dak and She Mya, where indicate the characteristics of warm current type maritime climate, humidity is high in all season and annual range of air temperature is nearly negligible. At Simusir and Vasi!' eva, where indicate the characteristics of cold current type maritime climate, humidity is high in all season and annual range of air temperature is $15^{\circ}C.$ As dry cooling power is relatively high in winter, working condition on deck is bad. Most of fogs are advection fog in the area of cold current type climate in summer.

  • Sea ices at the Tatarskiy Straitin the East/Japan Sea appear from November to April. Cold and fresh water, melted from the sea ices, may contain nutrients which are indispensable to spring bloom of phytoplankton and may provide a preferable condition to the spring bloom through changes in vertical structure of water column and stratification. Relation between the spring bloom along the Primorye coast and sea ices in the Tatarskiy Strait were investigated using multi-satellite multi-sensor data; ten-year SeaWiFS chlorophyll-a concentration data and PAR data, sea surface temperatures from NOAA/AVHRR, sea ice concentration and near-surface wind speed data from DMSP/SSMI, near-surface wind vectors from QuikSCAT, and others. We provided evidences of southwestward flowing cold water masses from sea ice and its relation of chlorophyll-a concentration. This study showed that year-to-year variations of chlorophyll-a concentration in spring were positively correlated with those of sea ice concentrations at the Tatarskiy Strait.

  • In the literatual studies on the suppurative osteomylitis(附骨疽), the results were as follows. Suppurative osteomylitis(附骨疽) is called 'Mudujur(無頭疽)', is concerned with Pyogenic osteomyelitis in western medicine. The pathogenic factors of Suppurative osteomylitis were caused by exposing to wind-cold-wetness evil, or body weakness, or wound a bodily injury caused by physical means. The symptoms of Suppurative osteomylitis was alternating episodes of chills and fever, pain on buttock or thigh in onset. The differential diagnosis of Suppurative osteomylitis was divided three parts. One was the stagnation of virulent fire-evil. Another was the deficiency of both vital energy & blood. The other was wind-cold-wetness evil. The treatments of Suppurative osteomylitis was clearing away heat-evil and wetness evil, removing blood stasis and promoting meridian. In the frequency of prescription, the most numerous prescription were Osintang(五神湯) and Hwangyunhaidoktang(黃連解毒湯), the next were Neitakganghwaltang(內托羌活湯), Taibangpungtang(大防風湯) etc.
