  • The control of the chronic degenerative diseases becomes a challenge in Korea as the aging of the population progresses. Accordingly, the importance of the control of the hypertension, one of the major chronic degenerative diseases, in the primary health care settings increases. However, such control activities are still minimal. This study gives brief description of how the rural residents who are currently registered for the control of the hypertension feel about the activities of the health centers, subcenters and the CHP posts, in relation to the control of the hypertension. We also describe the knowledge and practice of the registered hypertensive. In general, the knowledge, the acceptance and the satisfaction of the respondents about the hypertension control activities were not very high. Respondents being managed by the health center showed the highest knowledge, acceptance and satisfaction, and those being managed by the subcenters ranked lowest. The knowledge about the hypertension was not satisfactory. There were great variations among the items in terms of the proportion answered correctly. As many as 60% of the respondents take medication regularly but only 4.5% were practicing weight control regularly. Despite some limitations of the study, the results can be very useful for those planning hypertension control programs. The educational materials and the dietary protocols need to be developed in accordance with the regional social and food pattern, so that they can be utilized with minimal modification for each beneficiary. We also suggest to minimize the area a health personnel covers. In other word, running several small health posts at village level would be more effective than running a subcenter at the township level, in terms of the hypertension control.

  • The purpose of this study was to develope the Complete Airway Obstruction Maneuver Training Program and identify its effects on learning motivation, knowledge and skill of choking management in the primary school students. The subjects for the experimental group of 38 students and the control group of 39 students, all of whom are primary school students in Gwangju, the Republic of Korea. A non-equivalent control group pretest-posttest design was used and data were collected from November to December, 2003. During about 2 weeks, 2 times for a week with 80 minutes at a time, the complete airway obstruction maneuver training program was conducted in the experimental group. Experimental data were analyzed through SPSS/win 11.0 PC+, and the tests examining general characteristics between the experimental group and the control group were conducted through $x^2$-test. Fisher's exact probability test and t-test, and identifying the effect of the complete airway obstruction Maneuver training program was analysed through t-test and ANCOVA. The results of the study were as follows: 1. After intervention on the complete airway obstruction maneuver training program, Learning motivation in the experimental group was significantly higher than that of the control group. 2. After intervention on the complete airway obstruction maneuver training program, knowledge of choking management the experimental group was significantly higher than that of the control group(F=223.637, p=.000). 3. After intervention on the complete airway obstruction maneuver training program, skill of choking management the experimental group was significantly higher than that of the control group(t=46.800, p=.014). These findings suggest that the complete airway obstruction maneuver training program can facilitate learning motivation, knowledge and skill of choking management in the primary school students. Therefore it is considered that the complete airway obstruction maneuver training program can be utilized as a effective way to implement the 7th national curriculum for creative extra-activities.

  • Purpose : This was aimed to investigate the effects of empirical smoking prevention program on the knowledge of the harmfulness of smoking, attitude to smoking, smoking temptation among female high school students. Methods : This study used nonequivalent control group pre and post test design. The subjects were recruited from the first and second grade at the two girls' high schools located in Ulsan city, and randomly assigned to two groups(113 in the experimental group and 117 in the control). The intervention was both the events such as nonsmoking promulgation and experiential learning programs and student-oriented educational sessions(once a week for six weeks). Data was analyzed with X2 test, t-test and ANCOVA. Results : The mean knowledge was 12.5 for pretest and 13.7 for posttest in the experimental group, and 12.7 and 13.4 in the control group, retrospectively. The mean attitude was 71.0 for pretest and 72.2 for posttest in the experimental group, and 72.3 and 72.6 in the control group, retrospectively. The mean temptation was 15.0 for pretest and 14.7 for posttest in the experimental group, and 13.9 and 14.0 in the control group, retrospectively. There's no difference in the change of the knowledge of the harmfulness of smoking, attitude to smoking, smoking temptation between experimental and control groups. Conclusion : As the possible reasons, the subjects already had sufficient knowledge on the harmfulness of smoking, the research questionnaires were too plain to get any difference, the effect of intervention was too small to show a difference in such as short-term, and finally, there were many external factors. Hence, we recommend further studies with appropriate questionnaire for longer time.
