The subjects in this study were 312 dental hygienists in dental hospitals and clinics in Seoul, Gyeonggi province, metropolitan cities, Gangweon province and Gyeongsang province. After a survey was conducted in 2008, the collected data were analyzed with SPSS 11.5 program. The findings of the study were as follows: 1. In regard to perception of the credit bank system, 68.3 percent of the dental hygienists were cognizant of that. The dental hygienists from most of the geographic areas were aware of it, but all the forty three dental hygienists from Gangweon province who accounted for 13.8 percent didn't know about that. As for media by which they acquired information on that, many of the dental hygienists learned about it from their acquaintances (46.2%), but that was not the case for the dental hygienists from Seoul and Gyeonggi province. 2. As for expectations for the credit bank system, those from Gyeongsang province had the greatest expectations for that in six out of nine items, which included academic or job performance improvement, acquisition of credits, degree or certificates and access to new technology. 3. Concerning educational spending on the credit bank system, 18.9 percent and 8.7 percent from Seoul/Gyeonggi province and Gangweon province spent less than 30 thousand won, and 19.9 percent from the metropolitan cities spent 30 thousand to less than 50 thousand won. 4. As for the importance of the categories of their major in the credit bank system, those from Gangweon province attached the most importance to oral health education ($3.56{\pm}1.259$), and the dental hygienists from the metropolitan cities put the most stress on preventive treatment ($3.64{\pm}1.191$).

This study has an objective not only to be helpful to the understanding about students' career and employment preparation by investigating the present conditions which are related with vocational consciousness and job values of dental hygiene department graduating students. Study subjects were 350 female graduating students in 3-year-course College, dental hygiene department at five areas of Seoul, Gyeonggi, Gangwon and Gyeongnam. Data were analyzed using IBM SPSS Statistics ver. 19.0. Regarding job values, job prospect of dental hygienist is a little developmental (55.2%) and institution hoping to work is dental clinic (43.2%), reasons for employment in major area are good wage and working environment (24.0%). And regarding opinion about job, dental hygienist job is a measure for living income (69.7%). Regarding job selection conditions, 35.0% subjects replied good human relationship. In the questionnaires regarding professional job in vocational consciousness category, results showed high percentages in that 'the occupation is a job in charge of oral health improvement'; regarding academic area, 'scaling should be done better than dentist'; regarding human relationship, 'harmony between colleagues is closely related with job efficiency'; regarding work ethics, 'development of dental hospital (clinic) and dental hygienist is correlated.' In vocational consciousness of study subjects, higher major satisfaction showed significant differences in professional job consciousness and work ethics consciousness (p<0.05) and the correlation results in vocational consciousness areas showed all statistically significant correlations (p<0.01).

Entomopathogenic fungus Cordyceps militaris is famous for its medicinal efficacies. It has been reported to have various pharmacological activities such as anti-tumour, insecticidal, antibacterial, immunomodulatory and antioxidant. In this study, we investigated the effect of the extract of C. militaris (MPUN8501), which was identified by the analysis of the nucleotide sequences of 5.8S ribosomal RNA, on the function of liver. C. militaris powder was extracted using hot water extracts method as time, volume and temperature and using method as differential polarity of organic solvent. Each fraction was tested for the improvement of hepatic enzyme alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activity. The BuOH extracts (CME) had highest activity which was used for the test of toxicity and efficacy of C. militaris. The enhancing effect of CME on the activity of ADH and ALDH was much more than medicine, drink, natural tea etc. Thus CME promoted the resolution of alcohol and acetaldehyde in rats, inducing recovery to normal condition rapidly. Furthermore, oral administration of CME effectively protected the carbon tetrachloride-induced acute hepatic injury as revealed by the hematological parameters (levels of sGOT and sGPT) and histological observation. CME was ascertained to be safe by regulatory toxicity studies of single dose toxicity and genotoxicity. These results suggest that CME would be useful for the maintaining normal hepatic activity as a functional health food.
