Purpose: The purpose of this study was to examine the effects of interactive pictorial education on community dwelling older Korean adults' self-efficacy and knowledge for safe medication. Methods: A quasi-experimental, three-group pre- and post-intervention design was used in this study. The interactive pictorial education was designed to suit the learning patterns and psychomotor skills of older adults. The education content, dealing with safe medication, was delivered over three sessions. A total of 136 older adults from local senior centers were assigned to one of the three groups: a) interactive pictorial education plus information booklet (experimental); b) education only with information booklet (conventional); or c) no intervention (control). Results: Participants receiving interactive pictorial education had significantly higher self-efficacy (F=24.32, p<.001) and knowledge (F=24.26, p<.001) scores than the information booklet or control group at post intervention. Post-hoc analyses indicated that both the interactive pictorial and the information booklet groups had significantly higher self-efficacy and knowledge scores than the control group at the post-test point (p<.05). Furthermore, the interactive pictorial group had higher self-efficacy and knowledge scores than the information booklet group at the post-test point (p<.05). Conclusion: These results suggest that the interactive pictorial education is an innovative approach that provides a means for older adults to learn appropriate medication use to improve their own health. It empowers older adults with different literacy levels to enhance their self-efficacy and knowledge for the safe use of medication.

A simulated control group pretest-posttest design was used to investigate the effects of a health promotion education program on knowledge, attitude, and self-efficacy in sexuality, drinking, and smoking among college women. The subjects included 17 women in the experimental group, and twenty in the control group. This program was carried out for a total of four sessions, two hours per session once a week. The results were as follows； 1) Knowledge on sexuality, drinking, and smoking increased significantly in the experimental group compared to the control group (U＝66.50, p＝.001 ； U＝23.50, p＝.000； U＝29.50, p＝.000). 2) For attitude, only the attitude to drinking showed a significant difference between the two groups (U＝76.00, p＝.004). 3) For self-efficacy, only self-efficacy on drinking showed a significant difference between the two groups (U＝55.00, p＝.000). In conclusion, the health promotion program for college women increased their knowledge on sexuality, drinking, and smoking. This program affected their attitude and self-efficacy towards moderation in drinking. A even more appropriate education program on sexuality, drinking, and smoking for college women could be developed using this program by addressing the limitations in this study and repeating the study with a more varied sample.

Purpose: Women's weight perception and obesity-related quality of life were analyzed according to BMI (Body Mass Index). Methods: A survey was conducted using self-report questionnaires from 178 participants. The data analysis included descriptive statistics, frequency, percentage, t-test, ANOVA, Fisher's exact test and Kendall's tau using the SPSS version 14.0. Results: There were significant differences in BMI according to age (F=8.037, p=<.001), weight perception (F=60.71, p<.001), weight control experience (F=2.504, p=.013), weight control method (F=5.839, p=.001) and weight control success (F=-2.451, p=.016). There was a significant difference in obesity-related quality of life according to weight perception in the low weight group (F=5.587, p=.021) and in the obesity group (t=3.419, p=.003). Higher correlations were found between the women's BMI group, weight perception and obesity-related quality of life. Conclusion: A program to provide appropriate information for weight perception is needed for the low weight group. There is a need for a program about weight reduction as well as weight perception for the obesity group.

Chiral recognition models for resolving π-basic N-acyl-α-(1-naphthyl)alkylamines and π-acidic N-(3,5-dinitrobenzoyl)-α-amino alkyl esters on a (S)-tyrosine-derived chiral stationary phase (CSP) containing both π-basic and π-acidic interaction site have been proposed. In the models, the CSP was supposed to interact with the analytes through the π-π interaction between the 3,5-dinitrophenyl or the 3,5-dimethylphenyl group of the CSP and the 1-naphthyl or the 3,5-dinitrophenyl group of the analyte, and through the hydrogen bonding interaction between the appropriate N-H hydrogen of the CSP and the appropriate carbonyl oxygen of the analyte. In this instance, the alkyl substituent of the pertinent enantiomer of the analyte was found to intercalate between the adjacent strands of the bonded phase and consequently control the trends of the separation factors.

The purpose of this study was to identify the effect of providing toothbrushing by professionals as part of oral hygiene education for the elderly. We randomly visited 12 centers in the metropolitan city and analyzed the data of 114 participants among 310 early registrants aged >65 years, who participated in the study at all 3 time points. The subjects were categorized into an experimental group (odd-numbered visits) and a control group (even-numbered visits). Oral hygiene practices were provided for both experimental and control groups, but professional toothbrushing was performed in a different manner in the experimental group. Differences in plaque index (PI) according to the subjects' general characteristics and oral health status were assessed using the t-test, and the effect of PI difference between the experimental and control groups was assessed by repeated measure two-way analysis of variance. A stepwise multiple regression analysis was used to analyze factors affecting the PI. At baseline, the mean overall PI was 61.82. In both experimental and control groups, the PI significantly reduced from the baseline (p<0.01). At 5 weeks, the experimental group showed a decrease of 27.16 points from the baseline, and the 10-week PI was similar to the 5-week PI. The control group showed a decrease of 14.87 points from the baseline, and the PI increased by 5.74 points at 10 weeks. PI-related factors were gender and self-xerostomia. The PI was lower in the female group and the group with self- xerostomia (p<0.01). It is important to select an appropriate method to educate elderly subjects on proper removal of dental plaque and to habituate correct behavior, which requires inclusion of a direct toothbrushing intervention by a specialist.

A great deal of attention has been paid to the quality of life in citizens due to the increased number of long term life expectancy. reported as effective in the health promotion of the senior citizens. In this study, the principal investigator developed an exercise program for the senior citizens, which could be educated and managed by nursing staff. This kind approach may support the need of exercise program on regular base via the social organization, which may mean the intentional change of life style. The exercise program consisted of exercise, health education, and a direct the population of the senior A regularexercise has been nursing care. A quasi -experimental study was conducted to investigate the effects of excercise program on health of the elderly in senior citizen's center. Independent variable was a 9 weeks exercise program. Dependent variables were: 1) physical health [e.g. physical fitness(cardiopulmonary endurance, back muscle strength, grip strength, muscular tolerance, flexibility and body fat proportion), physiologic parameters(blood pressure, pulse, respiration. and blood glucose), and perceived physical health status; 2) mental health measured by depression score; and 3) cognitive perception of exercise measured by usefulness and self-efficacy. A total of 37 subjects was randomly assigned into either the control group (without the exercise program: n=18) or the intervention group(with the exercise program: n=19). The results of the study analyzed using a SAS, were as follows: 1) In physical fitness of physical health, there was a significant improvement in cardiopulmonary tolerance. back muscle strength. muscular tolerance and flexibility in the intervention group, compared to the control group, while no difference in grip strength and body fat proportion. The exercise program resulted in decreases in blood pressure, pulse, respiration and blood glucose within normal range and improvement of perceived physical health status in the intervention group. 2) There was a slight increase of mental health(depression score) in the intervention group compared to the control group. but without statistical significance. 3) There was a significant improvement in cognitive perception of exercise(e.g. usefulness and self -efficacy) in the intervention group, compared to the control group. It was concluded that the exercise program employed in this study was appropriate for women senior citizens and had a positive effect on health in general.

To study the health hazards and exposure status of manganese among female manganese workers, authors conducted airborne, blood and urine manganese concentration measurements, questionnaire and neurological examinations on 80 manganese-handling productive female workers(exposed group) in a manganese manufacturing facto in Pohang city and 127 productive female workers not handling manganese(control group) in other factories in the Pohang city. The results are; 1. Geometric mean concentrations of manganese in air and urine were $0.98mg/m^3\;and\;4.12{\mu}g/l$ and arithmetic mean concentration of manganese in blood was $6.94{\mu}g/dl$ in exposed group, significantly higher than those of control group(p<0.05). However, clinical and laboratory findings in exposed group were not statistically different from those of control group. 2. As age increase, positive rates of clinical symptoms also increased in the exposed group. However, in older aged group, the positive rates of symptoms and signs were statistically different from those of control group. We observed the same tendency in the positive rates of the neurological examinations. 3. There was statistically significant correlation between airborne and urine manganese concentrations(r=0.61, p<0.01) while there was no statistically significant correlation between airborne and blood manganese concentrations(r=0.29, p>0.05). The results suggest that urine manganese concentration was the best appropriate biomarker to estimate the exposure to manganese in respect to clinical symptoms and signs. In the analysis of correlation between urine and airborne manganese concentrations, it is required to adjust the present permissible exposure level(PEL) of airborne manganese.

In an attempt to measure effects of the Programmed Resistance Exercise on the daily performance of patients with rheumatoid arthritis, a quasi-experiment ; non-synchronised control group pre-post-test, was carried out for 8 weeks : from June 3 to November 29, 1996. 25 for the experimental group and 26 for the control group were conveniently sampled among registered out-patients on rheumatoid arthritis clinic of Anam Hospital, Korea University Medical Center. The programmed experimental resistance exercises were carried out by the experimental group five times a week for eight weeks. Before and after experiments, level of functional task performance, functional disability, joint mobility, ESR, CRP, self-efficacy and family support were measured and statistically analysed. The results of the analysis of the effects on the Programmed Resistance Exercise are as follows : 1. A statistically significant post-test effects on functional task performance were revealed : 1) the experimental group climbed up and down the 10 steps of the stairs significantly faster than the control group(P=0.0001). 2) the experimental group walked 100 m significantly faster than the control group (P=0.0000). 3) After the experiment, the experimental group could sit down and get up from chairs with no armrest as low as 30cm, 40cm, 50cm on their on, with no assistance as opposed to the control group who could not sit down and get up from such low chairs (P=0.0084). 4) the experimental group lifted 0-15 kg object up to their own heights with no specific strain than the control group (P=0.0000). 2. A significant reduction in the functional disabilities was revealed in the experimental group(P=0.0017). 3. A notable incresement of the joint mobility was revealed in the experimental group. 4. A decrease in the ESR in both the experimental and the control groups was noticed, however, the difference was not statistically significant (P=0.9546). 5. The CRP of both the experimental and control groups decreased with no significant difference (P=0.6022). 6. The self-efficacy increased significantly in the experimental group(P=0.0042), however, no significant effect of self-efficacy on the actual practice of the program was noticed. 7. The family support revealed to be significantly higher in the experimental group (P=0.0013), however, the effect of the family support on actual practice of the program revealed not significant. Judging from the results of these experiments, the resistance exercise program not only improves the functional capacity of rheumatoid arthritis, but also diminishes their functional disabilities and has a great influence on increasing their joint mobility, self-efficacy, and family support. Concluding, in promoting the daily performance of rheumatoid arthritis, the resistance exercise program would be an appropriate nursing intervention.
