Antimicrobial activity and bactericidal activity of Caesalpinia sappan L. extracts were investigated against five food-borne pathogens, E. coli, S. aureus, S. typhimurium, B. cereus and L. monocytogenes. Methanol extract of Caesalpinia sappan L. revealed antimicrobial activities against five pathogens. In particular, by paper disc diffusion the highest activity was shown against L. monocytogenes. Antimicrobial activities of methanol extracts showed the most potent activities, but hexane fraction had no activity. Fractions of ethyl acetate and butanol turned out to have higher antimicrobial activities against Gram(+) bacteria than Gram(-) bacteria. The minimum inhibitory concentration against five food-borne pathogens was 1.563 mg/ml on Gram(+) bacteria and 3.125 mg/ml on Gram(-) bacteria. The result of antimicrobial activity in a shaking flask method showed that bacterial growth rate fell by more than 99.999% at 3.125 mg/ml of methanol extract. The highest rate of viable reduction (99.998%) was shown at 0.781 mg/ml of methanol extract against L. monocytogenes. After five minutes of reaction between test strains and methanol extracts, the growth rates of five kinds of bacteria were reduced by more than 99.999% at a concentration of 100 mg/ml. Therefore, it is suggested that methanol extracts of Caesalpinia sappan L. can be developed as a natural sanitizer or disinfectant.

The crude polysaccharides(C-CPF, C-CPM, C-CPB) derived from fruiting body, mycelia and mycelia free broth of cordyceps militaris were obtained by ethanol precipitation of hot water extracts. After a batch fermentation of C. militaris was carried out in a 5 L jar vessel, endo-polysaccharide and exo-polysaccharide were obtained. They were demonstrated as the hetero polysaccharides which were composed of glucsose, galactose and mannose by performed with HPAEC(high pH anion exchange chromatography) and conformation of random coil by its complex forming ability with congo red reagent. They were purified by ion exchange (DEAE-cellulose) and gel filtration chromatography. They were monitered by phenol-sulfuric acid method and Bradford method. The NO induction activities of crude polysaccharides and purified polysaccharides derived from mycelia free broth were enhanced rather than LPS(lipo polysaccharide) which was used as a general NO inducer. These effects presumably contibute to the antitumor activities. The homogenieties and molecular weights of polysaccharides were determined by using Sepharose CL-6B. The yield, molecular weights and NO induction activities of C-CPFN Fr.III, C-CPMN Fr.III, C-CPBN Fr.II were 0.387, 0.408 and 0.153, 127 K 210 K and 36 K, 40.79%, 88.72%, and 104.17%, respectively.

The purpose of this paper is to provide the basic information concerning school health nursing activities in schools lacking in a school nurse, and the degree of satisfaction of trainess to the training course of school health nursing. The data for this study were collected by means of questionnaire from 150 teachers(100 of primary school and 50 of middle school)who attended the training course superintended by the Board of Education of Kyeong Nam Province from July 27 to August 6 in 1987. The main results of this study can be summarized as following; 1. General characteristics of the trainees: The majority of the trainees (71.3%) were in the age of twenties, 86.5% graduated from four-year teachers' college, 63.5% had less than five-year experience as a teacher. 2. 60.5% of the trainees were actually offering school health nursing services. 67.8% decided voluntarily to participate in the training course, and 62.7% attended the course for the purpose of obtaining health knowledge. 3. Only 4.2% of schools established appropriate health organization, and 34.5% were equipped with nursing clinic. But the main reason school health nursing activities were not performed very well was the insufficient supply of needed medicines and related materials. 4. School health nursing services in schools lacking in a school nurse were offered mainly by the teacher holding additional job of school health. class teacher and atheletic teacher. But the sanitary management for school meal services and community health activities were not carried out at all in many schools. 5. As a whole, trainees were satisfied with training program. But some subjects of the course did not satisfy them because those ones were so theoretical without any practice. 6. Many trainees wished the training course to be more concentrated on case studies which are helpful to solve actual problems. 7. 75% of trainees answered to have decided to perform school health nursing activities more actively than before. 8. Any significant relationship can not be found between trainees' general characteristics and their attitude to school health nursing activities after the training course. Only one factor-motivation to attend the training course-had the statistical significance of 8.7%.

The purpose of this paper is to investigate a new method for activating the metacognitive abilities that play a key role in the Mathematical Problem Solving Process (MPSP). The proposed research question is as follows: Can the MPSP activate metacognitive abilities of high school students in the pencil-and-paper environment using guidance material for metacognitive activities\ulcorner To solve this question, two case studies have been carried out. Two students for the study were selected via informal interview. They voluntarily took part in 13 experimental lectures. The activating paths of their metacognitive abilities in the MPSP were chronically described and analyzed. All the activating processes of the students focusing on the aspects of metacognitive behaviors were analyzed by means of interview, observation, self-report, and activity data. The two high school students participating in the MPSP voluntarily recognized and reflected their deficiencies in metacognitive abilities, and therefore maximized their own performance. They made quite significant progress in the course of activating their metacognitive abilities through voluntary participation and gained greater confidence in the MPSP. Hence they have become good problem solvers. They expressed not only the factors influencing their behavior but also their self-awareness during the metacognitive activities. In the long run, this experiment will increase possibilities for the internalization of the metacognitive process.

In this study the authors developed the practice-centered science camp program which was based on the review of out-of-school scientific activities and the standards of HASA (Hands, Head and Heart At Science Activity) curriculum emphasizing on hands-operated skills. After applying this science camp program we confirmed the validity of the program based on the students' responses at the camp. Using students' reports written during the camp and their essays written on the web-site after camp, we analyzed students' responses into four categories; knowledge, inquiry, hands-operated skills, and scientific attitudes. Also we evaluated the components of the science camp programs and students' perception of science and science-related attitudes using a questionnaire before and after the camp. In terms of contents and activities for the development and application of science camp, our result showed that the science camp program should be complemented to connect real life with high-tech science and include more activities related hands-operated skills and competition activities evoking constructive competitive spirits. In conclusion, we can infer that the agencies which take parts of the national policy enterprise related science education, such as Scientific Education Research Center, must develop and specialize science camp program with more competitive human resource system and economic support. Science educators should give more attention on joining school science education with out-of-school science education, which might have a positive effect on students' attitudes and participation toward science.

Purpose : This descriptive survey investigated the effects of clinical nurses' critical reflection competency, professional pride, and person-centered care practices on patient safety management activities. Methods : The participants were 183 clinical nurses working at a tertiary hospital in South Korea. The questionnaires consisted of the Critical Reflection Competency Scale for Clinical Nurses Professional Pride the Person-Centered Nursing Assessment Tool and Patient Safety Management Activities. The collected data were analyzed using descriptive statistics, t-tests, ANOVA, Tukey's HSD, Pearson's correlation coefficient, and multiple regression using SPSS 29.0. Results : The mean score for patient safety management activities was 4.65±0.34 out of 5. There were significant differences in patient safety management activities according to age (F=3.90, p =.010), education level (t=-2.56, p =.013), total work experience (F=3.87, p =.010), and the number of healthcare accreditation system experiences (F=5.22, p =.006). Patient safety management activities were positively correlated with critical reflection competency (r=.337, p <.001), professional pride (r=.271, p <.001), and person-centered care practices (r=.399, p <.001). The results indicated that person-centered care practices affected patient safety management activities (𝛽=.358, p <.001) with the explanatory power of 22.5%. Conclusion : To improve clinical nurses' patient safety management activities, it is necessary to develop participatory educational programs that can integrate skills and attitudes based on conceptual knowledge of person-centered care. Intervention studies are needed to test the effect of person-centered care on patient safety when applied in clinical practice.
