Purpose: The aim of the research was to define the effects of body image, career identity, and family health on depression in college students. Method: This descriptive research was conducted from the 1st to the 16th of July, 2018. The data was collected through convenience sampling of 222 college students. To draw conclusions from the data, we used statistical analysis of Pearson's correlation coefficients and stepwise multiple regression using SPSS WIN 21.0. Results: Depression showed negative correlations with body image, career identity and family health. Multiple regression revealed that the factors significantly influencing depression were body image, career identity, and gender. The total explanation of depression by these variables was 29.9%.

An electron microscopic study of the changes in chloroplast structure and chlorophyll contents as affected by the stress of nutrient deficiency is described. Each deficiency produces characteristic changes in the ultrastructure of the chloroplast. In nitrogen deficiency the compartments of grana are swollen and reduced in number. And then the grana break down. Therefore, the contents of chlorophyll are very decreased. Many osmiophilic globuli appeare in the plastid and also in the cytoplasm after the plastid are destoried. In potassium deficiency the changes of plastic are very different from the plastid of nitrogen deficience; The grana lamella are apparent, but swollen. There are many electron-dense masses in the fret-system and also in the cytoplam. And then the plastid break down into diffuse. But starch grains and osmiophilic glohuli are not observed in the plastid and cytoplasm of potassium deficience.
