Iris odaesanensis Y. N. Lee. is an important endangered and native plant belonging to the family Iridaceae in Korea. This study describes a method for rapid micropropagation of this species via from leaf, rhizome and root explants derived calli. Leaf, rhizome and root explants were cultured on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxy acetic acid (2,4-D) for callus induction. Rhizome explants yielded calli at a frequency of 72% when cultured at 1.0 mg/l 2,4-D. Calli were maintained at 1.0 mg/l 2,4-D. These calli were transferred to MS medium supplemented with 0, 0.5, 1.0, and 2.0 mg/l 2,4-D in combination with 0, 0.5, 1.0, and 3.0 mg/l BA for adventitious shoot induction. The highest number of adventitious shoot (228.9 per petri-dish) were formed at 1.0 mg/l 2,4-D and 1.0 mg/l BA. WPM medium was the best to convert calli into plantlets, where up to 98.2% of calli were regenerated into plantlets. This in vitro propagation protocol should be useful for conservation of this endangered plant.

This study was carried out in a part of conservative plans recovering natural ecosystem which will be submerged, as Hoengseong dam is being constructed around Hoengseong-Eup and Gabcheon-Myun. The submerged area was divided into 7 small areas to figure out what kinds of species of plants are and will be according to detailed geographic characteristics. In the center of the subdivided areas. Degree of Green Naturality, standing biomass, net 36production per year, and composition of plant species were investigated. The results are as following; 1. The surveyed area was classified into 8 degree by Degree of Green Naturality, and the appeared degree and the rate of occupation were 0(3.01%), 1(5.3%), 2(28.2%), 3(0.1%), 5(0.2%), 7(4.6%), 7(44.7%), 및 8(13.8%). 2. Standing biomass was 88,436.3 ton/year and net production per year was 12,960.3 ton/year. 3. The list of vascular plants identified in this study consisted of 86 families, 221genera, 1 variety, 3 formae and 306 species, totally summiting upto 310 species. 4. The 7 surveyed areas were largely occupied by Pinus community. In addition, there were Quercus mongolica, Quercus dentata, and Quercus acutissima communities.

Comparative Study on the Use of Pharmacist Advice between U.S. and Korea

( Lee,Eui-kyoung ) 한국보건사회연구원 1990 保健社會硏究 Vol.10 No.1

This study investigated the differences in the use of pharmacist advice between the U.S. and Korean university students. The variations in a person`s decision to use pharmacist advice in response to symptoms were examined based on Andersen`s model. A pre-experiment was conducted for the students taking similar courses using a self-administered questionnaire. For the 18 hypothetical symptoms, they were asked to decide how to respond to each of them for 7 days. After controlling for the symptom severity, U.S. students were apt to use pharmacist advice for less days, no matter how they perceived them. The results also showed that there were meaningful differences in the use between two countries after adjusting for differences in the predisposing, enabling, and need characteristics. A revised four stage model was successful in explaining the differences in the utilization. Application of modified version of Andersen`s model to U.S. and Korean university students yielded very unique findings, where the most predictive power was in predisposing variables. The meaning of the “country" was discussed in relation to the difference in the drug regulatory environment.

The purpose of this study is to compare overall educational belief and teachers' sense of self-efficacy of day-care teachers. The subjects of this study were 142 day-care teachers in the Cheon-Buk areas. The data were collected using questionnaires and analyzed by the statistical methods of frequencies, percentages, a Chi-Square test with SPSS program. The results of the study are as follows : 1. As the result of the investigation that what is the educational belief of the teacher according to the academic background, the personal history, and the type of day care-centers, it showed that statistically there was no significant difference. 2. Regarding the day-care teachers' sense of self-efficacy, according to the academic background was no significant difference. The teachers having 1 to 2 years of teaching experience showed the highest personal teaching efficacy and state- or public- run day-care centers teachers showed also high general teaching efficacy.

This study is intended to investigate medication compliance and polypharmacy of the diabetic patients by age group in order to determine the major factors that influence their compliance. 198 ambulatory diabetic patients were interviewed, and the sample was divided into three groups based on the age: Young age group under 75, Borderline age group between 55 - 65, Old age group over 65. According to the study results, medication compliance for the old age group was 72.6% whereas 85.1% for the young age group. Medication compliance significantly decreased as the age of the patients increased. Also the degree of polypharmacy, the rate which patients take more than 6 prescription drugs, was 45.9% for the old gruop, whereas 31.2% for the young group. As the most important factor of polypharmacy, the number of doctors was statistically significant. With regard to prescription factors related to medication compliance, the amount of prescribed medication is statistically significant between the compliance group and non-compliance group. In addition, the amount of information provided to patients by pharmacists was determined to be a very significant factor. Also the level of ease in understanding the medication instructions varied significantly between the compliance group and the non-compliance group. In light of the empirical data and results for the diabetic patients, it is necessary to develop and implement various programs to improve medication compliance and to decrease the level of polypharmacy among the elderly, or "old", diabetic patients.

The purpose of this study was to established the characteristic radiographic features in salivary gland diseases by means of sialography and scintigraphy. Sialograms and scintigrams with diseases of salivary gland were examined. In this group were 5 salivary stones, 14 sialadenitis, 17 Sjogren's syndromes and 8 benign tumors. The obtained results were as follows; 1. In the configuration of the shape of main duct, those revealed that modified curvilinear and curvilinear types were predominant in Sjogren's syndromes but reverse sigmoid and angular types were in sialolithiasis and sialadenitis combined with sialodochitis. 2. In the configuration of the course of main duct, those revealed that smooth types were predominant in sialadenitis and irregular types were predominant in Sjogren's syndromes and benign tumors and irregular types were seen in all salivary stones and sialadenitis combined with sialodochitis. 3. In the type of intraglandular pattern, those revealed that destructive changes of salivary duct system and parenchyma were severe in sialadenitis and salivary stones and predominantly severe in Sjogren's syndromes. 4. The function of salivary gland was decreased severely in Sjogren's syndrome, and also decrease in salivary stone and sialadenitis. In benign tumor, the uptake of radioisotope was not seen in lesion and the function of salivary gland decreased in its remaining normal parenchyma.(J Korean Oral Maxillofac Radiol 1999:29:175-189)
