The numerical model simulation was conducted to evaluate complex wind flows over Pusan Metropolitan City, a typical mountainous coastal urban area of Korea. SAIMM(System Application International Mesoscale Model), a meteorological prediction model, includes surface heat budget and relatively detailed parameterizations of the atmospheric surface and planetary boundary layers. The experiment was carried out for August 17 to 18, 1995. The simulated daily variation of wind flows is well represented in the typical sea/land breeze and mountain/valley wind alternation in the model region with irregular topographic conditions. While the valley wind occurred before sea breeze by surface heating blows to the top of the mountain in summer morning, the speed of sea breeze which directs inland from the coast area grew stronger and strong convergence zones were formed at several valley areas of inland in the afternoon. The mixing height of inland reached approximately 1300m by ascending stream and prevailing heat convection during the day time. Compared the calculated results with the horizontal wind data observed from Automatic Weather System, the characteristics of local circulation in area studied were discussed.

Since Berger and Hinglais published the first account of IgA nephropathy in 1968, IgA nephropathy has been recognized as a distinct form of primary golmerular disease and is recognized as most common form of glomerulonephritis. The diagnostic features of primary IgA nephritis are measngial deposits of IgA, measanial expansion and proliferation with variable acute proliferative and sclerotic glomerular lesions in absence of systemic desease, but measangial deposits are also seen in Henoch-Schonlein purpura and systemic lupus erythematosus and in association with certain other disease such as hepatobiliary disorder. It lupus erythematosus and in association with certain other disease such as hepatobiliary disorder. It has now become clear that several different clinical conditions share this common immunopathology. Several possible immnuopathogenesis have been found and it felt that IgA nephropathy should be regared as a syndrome. IgA immune complex is the most important pathogenical role in glomerulonephritis whth mesangial IgA deposits. Several hypotheses have been proposed to explain the occurence of nephritogenic IgA class immune complexes. Increased production of IgA due to and impaired immunoregulation and physiological immune response to acute antigen exposure, and decreased clearance of IgA due to impaired macrophage function. Activation of the alternative pathway of complement cascade in IgA nephropathy can result hypocomplementemia in active cases and the deposition of complement is induced by IgG/IgM codeposits, the deposition of complement is required for glomerular injury which is responsible for the alterations in glomerular function. 41 cases of renal biopsy specimens were selected out of 133 renal biopsy cases and summerized with correlation to their light microscopic and immunofluorescence findings, which obtained the period of Sep. 1986-Oct. 1988 at the department of Pathology, Keimyung University, Dongsan Hospital, Taege, Korea. The results were as follows: 1) The incidence of IgA nephropathy was 30.8% of all rnal biopsy cases. 2) Sex distribution showed slight male preponderance with male: female ratio of 1.05:1. 3) Age distribution were 0-9 years 2.4%, 10-19 years 19.5%, 20-29 years 46.3%, 30-39 years 14.6%, 40-49 years 7.3%, 50-59 years 7.3%, 60-69 years 2.4%. The young age group of age 10-29 years was the most prevalent. 4) The clinical symptoms were hematuria 71.8%, proteinuria(below lg/day) 4.9%, the rest above lg/day, nephrotic syndrome 24.3%, edema without nephrotic syndrome 31.7%. 5) The distributions of light microscopic findings were minimal change 19.5%, mesangial proliferation 36.6%, focal/segmental proliferation 7.3%, diffuse proliferation 17.1%, sclerosis 2.2% and crescents 2.4%. 6) Immunofluorescence study significant granular mesangial deposits of IgA and IgM 100%, IgG 75.6%, C?? 80.4%, fibrinogen 63.4%.

The purpose of this study is to establish the thematic roles based on semantic features such as CONTROL, CAUSE, TELICITY, and CHANGE. In order to achieve this purpose, it is shown that aktionsart plays an important role in determining the thematic roles. In this respect, thematic roles are classified as follows: ◁그림삽입▷(원문을참조하세요) In the system, Spatial Roles consist of Goal, Source, Theme, and Location, Logical Actors consist of Agent, Actor, and Instrument, and Logical Recipients consist of Patient, Experiencer, and Recipient. This system can solve the difficulty in analysing thematic structures, such as the distinction between spatial roles and logical patients as well as various semantic properties of agent described by previous studies. In addition, the system shows the notional differentiation among thematic roles considering semantic features such as CONTROL, CAUSE, TELICITY, and CHANGE.
