Nosema sp. infection in the Indian tasar silkworm, Antheraea mylitta exerts a complex of influences on its host. The instar duration was extended significantly (P<0.001) except in $1^{st}$ instar. The infected larvae took about 48 days to reach the spinning stage against 40 days in the uninfected ones. The final weight attained by the larva at the end of each instar of development declined significantly following infection, as did weight gain and relative growth rate (RGR). The growth recorded/ day declined in infected larvae compared to uninfected ones from 8.2% during $1^{st}$ instar to 43.3% during $5^{th}$ instar. Food ingestion and digestion increased with advancement of the instar significantly irrespective of the status of the larvae but the relative consumption rate (RCR) declined. These parameters significantly declined in infected larvae (except food digested during $2^{nd}$ instar). The decline was more during $3^{rd}$ instar. In contrast, the approximate digestibility (AD %) was significantly higher in infected larvae than uninfected ones leaving the $1^{st}$ instar larvae unaffected. The efficiency of conversion of ingested food (ECI) and efficiency of conversion of digested food (ECD) did not change in a patterned way following the microsporidia (Nosema sp.) infection. The values of ECI significantly changed during $2^{nd}$, $3^{rd}$ and $5^{th}$ instars; while the change in ECD during $2^{nd}$, $4^{th}$ and $5^{th}$ were significant. During the entire larval life all the parameters tends to decline significantly following microsporidia infection but AD registered a significant increase. Nosema sp. spore concentration has increased 270.7 times during larval development in the course of experimentation.

Food consumption and conversion efficiency of new bivoltine hybrids (CSR2$\times$CSR4 and CSR2$\times$CSR5) were studied under restricted feeding levels (10, 20 and 30% less quantity of mulberry leaves). The data were compared with a control fed with standard quantum of feed as per the recommendation. The nutritional indices parameters i. e. ingests, digesta, approximate digestibility (%) and reference ratio were recorded higher in control batches compared to less feed batches while nutritional efficiency parameters i. e., ECI and ECD to cocoon and shell were recorded significantly higher in restricted feeding level batches. This increase is attributed due to the physiological adaptation under nutritional stress condition.

The general commercial printing meets the customer's diverse demand by using spot color besides process four color. Especially, by using spot color for printing the enterprise's logo or specific color, we can see the effect of printing is getting better. The objective of this study was to examine the quality of spot color reproduction with Inkjet for 2 types of paper and Dye sublimation in ICC-based color management system. ICC profiles were generated for each device using ECI 2002 visual target and evaluated for the accuracy of each printer's color profile. The test chart consisting of Pantone color 1140 was selected to test the quality of spot color reproduction.

Extrapolation off the boundaries of scattered data is an intrinsic feature of interpolation. However, extrapolation causes serious problems in stereo-vision and mapping, which has not been investigated carefully. In this paper, we present novel schemes to eliminate the extrapolation effects for the generation of a digital elevation model (DEM). As a first step, we devise point distribution criteria, namely COG (Center of Gravity) and ECI (Empty Center Index), and apply rigorous and robust elimination based on the criteria. Compared with other methods, the proposed schemes are computationally fast and applicable to a wide range of interpolation techniques.

This study investigated the relationships of care- and justice-oriented morality by gender and sex role identity among adolescents, and young and middle-aged adults. The subjects were 115 males and 125 females between 16 and 59 years of age. Instruments were the Ethic of Care Interview(ECI), the Korean Defining Issues Test(DIT), and the Korean Sex Role Inventory(KSRI). Age was found to be a significant factor in both care-and justice-oriented morality; that is, young and middle-aged adults demonstrated higher care-oriented morality than adolescents. While, adolescents and young adults demonstrated higher justice-oriented morality than middle-aged adults. Females exhibited higher levels of care- and justice-oriented morality. A significant interaction effect was found between gender and age for justice-oriented morality.

This study investigated the relationships of care-oriented morality and justice-oriented morality to gender and sex role identity in young adults. The subjects of this study were 42 males and 46 females, the age of 30 to 39 years old. Care-oriented morality was assessed by the Ethic of Care Interview(ECI) and justice-oriented morality was assessed by the Korean Defining Issues Test(DIT) while sex role identity was assessed by the Korean Sex Role Inventory(KSRI). Care-oriented morality of most of the subjects was on level 2. The P(%) score of justice-oriented morality of most of the subjects was found to be pretty high. Sex differences were found both in the levels of care-oriented morality and justice-oriented morality. That is, women were higherthan men both in care-oriented morality and justice-oriented morality. However, no significant difference in sex role identity types was found both in the levels of care-oriented morality and justice-oriented morality.

This Study investigated the relationships of care-oriented morality to gender and sex role identity in young adults. Care-oriented morality was assessed by the Ethic of Care Interview(ECI) while sex role identity was assessed by the Korean Sex Role Inventory(KSRI) with a sample of 48 men and 42 women between 20 and 35 years of age. The level of care-oriented morality of most of the subjects was Level 2. There was a significant difference between men and women in level of care-oriented morality by both x2 and ANOVA. That is, women averaged and levels 2.5 and 3 while men averaged levels 1 and 1.5. The ANOVA reveled difference in sex role identity types by levels of care-oriented morality on the ANOVA test.

The objective of this study is to investigate learning factors (stability, attention and activation) in school by electroencephalogram (theta, alpha and beta waves) analysis during relaxed or concentrated. In order to measure electroencephalograms, MP 150 by Biopac and ECI Electro-Cap are employed. Three types of color temperatures (3000K, 5000K, 7000K) are used and 13 undergraduate and 12 graduate students are selected as experimental subjects. When subjects are relaxed during contemplation or concentrated during mental arithmetic, we compare with stability, attention and activation indices. The test results show that subjects were stable when color temperature is 5000K. Subjects gave best attention when color temperature is 7000K. Subjects activated well when color temperature is 3000K during relaxed attention. However, subjects activated rigorous when color temperature is 7000K during constrained attention.

Feeding is an important aspect of insect nutrition which in turn supports growth, development, reproduction and survival. The impact of quantitative feeding on nutritional parameters of fifth instar Antheraea mylitta larvae was studied by providing fresh leaves of Terminalia tomentosa for 1 to 4 times a day. All the parameters improved upon providing fresh diets more times over the single diet (1FD). The absolute body weight increased with increase in number of feeds/day significantly (P<0.001). While the maximum weight recorded was 29.61 g in 1FD, the respective weights for two feeds/day (2FD), three feeds/day (3FD) and four feeds/day (4FD) were 39.41 g, 40.63 g and 42.66 g respectively. Feeding period and instar duration were declined (P<0.001) and survival increased significantly (P<0.001) upon increase in the number of diets. Nutritional indices like ingestion, digestion, relative consumption rate (RCR), relative growth rate (RGR) and gain in body weight increased significantly with the increase in number of feeds/day, but approximate digestibility (AD) and efficiency of conversion of ingested food (ECI) declined, while efficiency of conversion of digested food (ECD) did not change.
