Purpose: Oral lichen planus (OLP) has generated many discussions and been associated with much controversy for a long time. A reliable diagnosis of OLP has proven challenging and significant disagreements concerning its diagnosis has continued. Therefore, the aim of this study was to apprehend newly proposed diagnostic criteria of OLP and oral lichenoid lesion (OLL) and to evaluate difference of final diagnosis of OLP and OLL in accordance with type of diagnostic criteria. Also, direct immunofluorescence (DIF) was compared to evaluate the value of DIF between two groups. Methods: Fifty-two patients with DIF result were retrospectively reviewed. The selected patients were classified by the modified World Health Organization (WHO) diagnostic criteria of OLP and OLL and by criteria proposed by American Academy of Oral and Maxillofacial Pathology (AAOMP). Results of DIF in OLP and OLL were classified by deposition intensity or pattern of fibrinogen. The classification of fluorescence pattern in each specimen was graded as positive, possibly positive or negative. Results: Patients diagnosed as OLP were a few more when the modified WHO diagnostic criteria were used than when criteria proposed by AAOMP were used. There was no statistical difference of DIF between OLP and OLL by applying the WHO modification criteria or criteria proposed by AAOMP. Conclusions: The final diagnosis of OLP could be changed in accordance with type of diagnostic criteria and difference of DIF between OLP and OLL was not found.

An emphasized analysis and reviews on the progress of pesticide managements for the past 10 years through the statistics in Korea are summarized in this continued studies in connection with the fundmental aspects and direction of advanced pesticide industry and improved plantprotection policies for 1980's. Remarkable development and changes are observed in the plant species and varieties, plantation practices and production techniques as well as pest infestations and controls in the last decade, but no normal achievement and operations are recognised on the pesticide management and marketing system especially. Realistic plant protection adminstration and pesticide regulations in accordance to the industrial modernization and pest management advancement must be adjusted in accordance with national economic progress and desirable agricultural structure for 1980's. Special considerations are stated on the strengthening of research and inspection program for the quality products and control with the efficacy and safety use of pesticides. More serious attentions are noted on the over production and flooded stocks under struggled market demands and sales competitions with lethal financial difficulties by producers. Through the status analyzed for the last decade, the integrated past management and cooperative basic control pattern under positive self-forecasting system by farmers are also urged for the effective and economic pest control measures. The problems and solutions discussed here ell the advanced pesticide management as well as the cooperation on the self-ordered quality control and market managing systems in 1980's as it is a desired projection for the further improvement. Most of outstanding and necessary statistics and data in the past decade are also summarized here for references in connection with the previous report.

Soilcrete has been the traditional material for the paving and soft ground improvement techniques. But because the durability is not excellent and the quality is not homogeneous, it has not been used for the various purposes up to date. And because the quality of soilcrete is apt to be changed by the content of water and soil stabilizer, and the kind of soil and soil stabilizer, it is not free of cares. But with the increase of naturally oriented needs for the light traffic road such as pedestrian roads of the garden, golf courses and sidewalks, the cases of soilcrete paving has been increased recently. This study aims at making the reference table of the mix design in accordance with the required design specifications for the soilcrete admixtures by the FGC soil stabilizer by using the statistical experiment method. The treated soil is the clay which are widely spreaded in Korea. As the results of this study we can derive the effective reference mix design table for the clay soil treated by the FGC soil stabilizer in accordance with the compressive strength of 50∼200kg/$\textrm{cm}^2$ soilcrete with respect to the contents of water, soil stabilizer and fine sand.

This study investigated characteristics of buckling load and effective buckling length by member rigidity of dome-typed space frame which was sensitive to initial conditions. A critical point and a buckling load were computed by analyzing the eigenvalues and determinants of the tangential stiffness matrix. The hexagonal pyramid model and star dome were selected for the case study in order to examine the nodal buckling and member buckling in accordance with member rigidity. From the numerical results, an effective buckling length factor of adopted models was bigger than that of Euler buckling for the case of fixed boundary. These numerical models indicated that the influence of nodal buckling was greater than that of member buckling as member rigidity was higher. Besides, there was a tendency that the bifurcation appeared on the equilibrium path before limit point in the member buckling model.
