A CdS single crystal was grown by using sublimation method. Lattice constants, a_o and c_o, obtained by using extrapolation were 4.1318 Å and 6.7122 Å, respectively. The carrier density was ∼10^(23) m^(-3) and the mobility was 2.93X10^(-2) ㎡/V-sec from measured Hall data at room temperature. The mobility has a increasing tendency in proportion to T^½ from 33 K to 150 K and a decreasing tendency in proportion to T^(-2) from 180 K to room temperature. The short wavelength band peak measured from photocurrent was due to intrinsic transition, and the energy value of this peak was equal to the energy band gap of CdS photoconductor.

PURPOSE. The purpose of this study was to assess the prevalence and extent of clinical attachment loss of periodontal tissue and to find out variables related to clinical attachment loss (CAL) in Korean adults older than 40 years of age. MATERIALS AND METHODS. Data were collected from 2,519 subjects who were part of a cohort study conducted in Ansan city by Korea University Medical School for Korean Genome project. Age, sex, smoking, drinking, fast glucose, blood pressure, obesity and total cholesterol levels were examined. The oral examination included probing pocket depth, gingival recession and CAL of Ramford's teeth. The severity of periodontitis was classified based on the mean value of CAL. The relationship between each risk factor and the severity of CAL was independently estimated using the chi-square test, the test or one-way ANOVA. Multiple regression analysis was used to determine the significance of each factor in the periodontal disease. RESULTS. The prevalences of clinical attachment between 1 and 3 mm, between 3 and < 5 mm, and ${\geq}$ 5 mm were 80.27%, 16.75% and < 1%, respectively. Although the univariate analysis showed age, gender, smoking, fasting glucose, blood pressure and total cholesterol levels were significantly related to the severity of CAL, multiple regression analysis indicated that age (P < .0001), gender (P < .0001) and smoking (P < .05) were only significantly related. CONCLUSION. Older age, male gender and smoking were significant risk factor for the increase of CAL, and these may be useful indicators of periodontitis high-risk groups.

The present study compared the effectiveness of virtual influencers (VIs) to human influencers through the theoretical lens of the uncanny valley and parasocial relationship using an online experiment. Specifically, we posited that highly humanlike VIs may evoke the feeling of the uncanny valley, as compared to human influencers or cartoonlike influencers, which, in turn, would act as a psychological barrier to building a parasocial relationship with the specific type of virtual influencer and decrease advertising attitude. The results indicated that people do feel the uncanniness from both highly humanlike and cartoonish influencers as compared to human influencers. This particular psychological experience negatively influenced the parasocial relationship, which, in turn, negatively affected the attitude toward a social media advertisement featuring the VIs. However, importantly, this effect was moderated by individual differences in anthropomorphism. This is one of the first studies that directly compared the effectiveness of different types of social media influencers in a rigorously designed experimental setting and expands the previous research on Vis, uncanny valley, and parasocial relationship. Both theoretical and managerial contributions of the study were discussed.
