The methods controlling the confounding factors were discussed using the data of secondary infertility with induced abortion. Mantel-Haenszel method and logistic model were applied in the analysis to find out which factors were confounding and/or effect modificaton variables. In the logistic analysis, the main effect of induced abortion, spontaneous abortion, age and interaction effect between induced abortion and spontaneous abortion werechosen as independent variables being regressed into logistic functions. Spontaneons abortion was interpreted as a potential confounder and at the same time potential effect modifier and age wasinterpreted as potential confounder. Spontaneous abortion was shown to be more important influencing factor than age to the secondary infertility. In the course of logistic analysis, the problem of parameter estimation and hypothesis testing, assessing the fitness of a model, and selection of the best model were briegy explained. For the program of logistic model, FUNCAT Procedure of SAS package was chosen.

A study on the Aedes togoi to find out important biological and ecological factors as an efficient vector of filariasis, was carried out on Che-Ju Island for two years from 1968 though 1969. Results obtained are as followings: Geographical distribution of the mosquito breeding habitat was found to be extensive covering circular areas of about three km distance along the shore line. The main breeding sites were rockpools and smaller holes on rocks retaining tide and/or rain water with high larval density; water tanks, pots, and other artificial containers retaining only rain water around the houses located within the area with relatively low larval density. Species constitution of adult mosquitos collected in the study villages consisted largely of Aedes togoi with a range of 70-90 per cent by village. The pH of the breeding sites ranged from 5.0 to l0.0, and the chloride content from 0.01 to 28.75 (gm/l). More than fifty per cent of examined sites, however, had pH 5.6-6.5 and chloride content of less than 1.0 gm/1. The natural infection rate of A. togoi by filaria showed proportional relationships with microfilaria rates among the human population by area. Experimental infection of A. togoi by human and dog filaria demonstrated that this species is an efficient vector for both filaria species proved by natural infection as well as experimental infection. Susceptibility of both larva and adult of A. togoi to insecticide, DDT and dieldrin, showed considerable sensitivity in all villages tested.
