Social distance toward schizophrenia among parents of adolescents
Social distance toward schizophrenia is a reason for delays in receiving early treatment for the disorder. This study attempted to identify the factors underlying social distance. The participants were 2690 parents of adolescents. Factor analysis using a social distance scale identified two factors: private relationship and social relationship. Regression analysis revealed that gender, age, and participation in welfare activities for people with mental illnesses had independent effects on the factor private relationship (p < 0.05). These results suggest that women aged 40 - 49 years should be targeted for activities that attempt to counteract social distance and that they would benefit from taking part in public welfare activities for individuals with mental illnesses.journal articl

Irrigation system operations and effective rainfall- Case study on low land paddy irrigation area -
Rainfall over irrigated paddy fields can save irrigation water volume which could be stored reservoirs. The estimation of saved w ater volum e (effective rainfall) and its relation with rainfall has been the m ajor issues in w ater system planning. Irrigation system m anagement which activates the effective rainfall created on the paddy plots has been neglected. Case study on irrigation system managements for effective rainfall was exam ined. Irrigation water discharge after rainfall, the timing of irrigation w ater operations, the duration of restricted irrigation w ater, the volum e of effective rainfall, the contribution of irrigation system operation for flood mitigation was surveyed.
A half of rainfall events cause irrigation w ater decrease. The decrease of irrigation discharge after rainfall is not large. Only a few rainfall events which are in the ripening stage or over 90mm cause com plete irrigation stop. Irrigation w ater decreases quickly after rainfall and continues long. About 30% of operations are implem ented before peak rainfall. Irrigation decrease continues at least 15 hours and durations of 30% of irrigation decrease are m ore than 3 days. Effective rainfall on project level water requirem ent is estimated by hourly irrigation w ater discharge. Effective rainfall divided by rainfall is sm all as com pared w ith other surveys. The irrigation w ater decrease effects m uch on shortening of inundation duration and little on reduction of maximum flood discharge.articl
