Purpose : Pneumococcal protein vaccine based on pneumococcal surface protein A (PspA) is in development with the potential to offer a broad range of protection against different strains. PspA elicits protection in mice against fatal sepsis as well as carriage and lung infection. This study was performed to investigate the frequency of PspA families among Streptococcus pneumoniae recovered from Korean children and adults. Methods : A total of 89 pneumococcal isolates was included in the study. They were capsule serotyped by the slide agglutination assay with commercial antisera. PspA families were determined with polymerase chain reaction using the pair of primers for family 1 and family 2. Results : Seventeen pneumococcal serotypes were found in a total of 89 isolates. PspA typing was able to ascertain 79 of the 89 isolates (88.8 percent). Among these, 20 (22.5 percent) isolates were family 1 PspA, 59 (66.3 percent) were family 2. Moreover, because 9 (10.1 percent) isolates were of positive reactions for both, families 1 and 2 primers, the potential coverage of PspA vaccine was 98.9 percent. PspA families were not associated with age group, source of isolates, or penicillin susceptibility. However, the relative distribution of family 1 isolates to family 2 isolates was significantly different over capsular serotypes. Conclusion : The finding that 98.9 percent of Korean isolates belonging to PspA families 1 and 2 support the hypothesis that a human PspA vaccine covering a few PspA families could be broadly effective. The monitoring of the PspA families derived from large population-based isolates will be necessary in the context of vaccine development.

This study was performed to identify the effects of the improvement of brain function by CST on the elderly with the 2nd or 3rd grade of long-term care insurance service. A quasi-experimental design using a nonequivalent control group, pre-post test was used. A total of 12 elders (6 in the experimental group and 6 in the control group) were recruited. Upledger CST(10-Step Protocol) was performed on each subject for 50 minutes per session, once a week, for a total of 8 treatments over an 8 week period from Jan to Feb 2015. The brain function quotient was measured before the 1st CST and after the last CST by portable EEG measurement device using a 2 Channel neuro-feedback system. The data was analyzed by SPSS (Ver. 18.0) program. After CST intervention, the attention quotient (AQ), level of tension, anti-stress quotient (ASQ), emotion quotient (EQ) and brain quotient (BQ) of the experimental group was significantly better than that of the control group. These results showed that the CST was effective in reducing the level of fatigue by the AQ, increasing the physical and psychological stress relief by the ASQ, emotional balance by the EQ, and improving the total brain function by the BQ. Therefore, CST can be used as an effective intervention for improving the health and brain function of the elderly in health facilities.

Background: Dental hygienists emphasize the ethics of healthcare workers. To effectively cope with various ethical conflicts, it is necessary to establish a reasonable ethical value system. Therefore, this study intends to use basic data to develop ethics education programs and ethical value evaluation tools. Methods: We conducted a questionnaire survey targeting dental hygienists between January 1 and 15, 2023. A total of 251 people's responses were analyzed with SPSS Win 25.0, to perform frequency, t-test, one-way ANOVA, and multiple regression analysis. Results: The idealistic propensity (3.82 points) was higher than the relativistic propensity (3.42 points), and the absolutists showed a deontological position in the partnership area and dental hygiene work relationship area(P < 0.001). Regression analysis of factors affecting ethical values revealed that idealism (β=,444, p=0.000), marital status (β=-0.123, P = 0.035), and position (β=-0.154, P = 0.009) were significantly related to ethical propensity. Conclusion: It is necessary to develop an ethics education program that considers the ethical propensity of dental hygienists and establish firm ethical values by implementing situation-oriented ethics education that can respond to many changes and conflicts.

International relations in the 21st century is featured by boundless competition among nations to secure sufficient energy resources for achieving economic development. Resource diplomacy, therefore, is competitive in its nature, which is derived from the fact that resources of the globe are limited. Chinese recent economic growth has been possible mainly due to its success in resource diplomacy. The Chinese resource diplomacy has shown two different patterns according to target regions. On the one hand, China has pursued multilateral approach to Central Asia region, by which China aimed to secure energy with joint exploration method in the region. Chinese resource diplomacy toward Africa, on the other hand, has been based on bilateral approach combined with unit-centered economic aid to African nations. This difference in Chinese foreign policy pattern seems to be derived from three factors: namely, Chinese strategic considerations on geopolitical condition, regional security sensitivity, and legacies of Chinese long-time non-alignment diplomacy since the 1950s. Whether China is able to maintain the current pattern of resource diplomacy will be depended on how wisely China pursue its relations with two other global powers: Russia in the Central Asia and the U.S. in Africa. In this regard, the Chinese resource diplomacy is expected to work as determining factor of shaping a pattern of tri-lateral strategic relations among the U.S., Russia, and China. Chinese resource diplomacy thus will determine the future direction of the global politics in terms of strategic arrangement.

Background: The elderly population aged 65 or older in Korea is expected to continue to increase to 18.4% in 2023, and to enter a super-aged society at 20.6% in 2025. In clinical practice, the elderly discrimination of dental hygienists may experience difficulties during dental hygiene treatment due to an increase in the number of elderly patients due to aging, which can lead to maladjustment to work and turnover, so education on the understanding of the elderly is essential for students in the Department of Dentistry, who are prospective dental hygienists. Accordingly, a study was conducted to prepare for a super-aged society by studying the relationship between elderly discrimination and the knowledge and attitudes of the elderly, and to change the curriculum of universities and develop programs related to the elderly. Method: 204 students enrolled in the Department of Dentistry in D area were analyzed using the SPSS/WIN 25.0 program. The subject's geriatric discrimination, knowledge about the elderly, and attitude toward the elderly were calculated as the mean and standard deviation. T-test and one-way ANOVA were performed to verify the difference in geriatric discrimination according to the general characteristics of the subject, with a Scheffe' test applied for post-hoc analysis. Correlation analysis was conducted on the subject's geriatric discrimination, knowledge about the elderly, and attitudes toward the elderly. Results: Geriatrics scored 2.03±0.36 out of 4. Knowledge about the elderly was categorized as follows: physical domain 0.57±0.15; social domain 0.36±0.17; and psychological domain 0.35±0.20. The attitude toward the elderly was 3.86±0.27. Knowledge of the elderly averaged 11.27±3.30 points out of 25. The question with the highest percentage of correct answers to knowledge about the elderly was 'physical strength tends to decrease with age', which was 93.1%. The attitude toward the elderly according to the general characteristics of the study subjects showed significant differences in gender (p=0.040), age (p=0.026), and life experience with grandparents (p=0.001). The elderly discrimination of the study subjects showed a negative correlation in both attitude and knowledge toward the elderly, and among the elderly discrimination, there was a high positive correlation with regard to emotional avoidance (r=.892, p<0.001). Conclusion: College students are the leading players in caring for the elderly and are directly affected by aging social problems. Therefore, it is considered necessary to apply various programs in the state, society, and educational institutions to avoid negative prejudices that lead to positive thinking and discrimination against the elderly.
