  • This study was conducted to test the effect of a self regulation education program as a nursing intervention with chronically ill patients. A quasi experimental research(non equivalent control group pretest-posttest design) was used in this study. The subjects were 30 non insulin dependent diabetic patients(experimental group : 14 patients, control group : 16 patients). The study was carried out from May, 1995 to February, 1996. Data were collected before the education program, immediately after & 2 menths later and were analyzed with repeated measure ANCOVA, paired t-test and t-test. The results are as follows : 1. There was a significant difference in self efficacy between the two groups(F=27.61, P=0.000). There was a significant difference according to experimental stages(F=33.09, P=0.000) and interaction between education and experimental stages(F=30.21, P=0.000). 2. There was a significant difference in self care behavior between the two groups(F=27.05, P=0. 000). There was a significant difference according to experimental stages(F=31.14, P=0.000) and interaction between education and experimental stages(F=28.88, P=0.000). 3. There was a significant difference in glycemic control between before the education program and 2 months iater in the experimental group (t=2.88, P=0.013). But there was no significant difference between before the education program and 2 months later in the control group. These results suggest that a self regulation education program is effective in promoting & maintaining self care behavior and in improving glycemic control.. Thus this program can be recommended as an effective nursing intervention for chronically ill patients including diabetic patients.

  • The purpose of this study is to investigate whether the appropriateness of gustatory features in product design affect product evaluation and accompanied response by using functional magnetic resonance imaging(fMRI). Through the pilot survey, we categorized the product designs into two groups based on the level of the appropriateness. The total of 40 product designs were selected as the experimental stimuli. 15 right-handed participants(mean age = 23.33, SD = 1.7) were scanned with 3T MRI machine(ISOL Tech, Oxford OR63). The experimental stimuli were passively presented inside the scanner. In post scanning session, participants were asked to measure their preference and buying intention to the product designs. The results show that both the preference and buying intention were significantly higher for the high appropriateness condition compared to those of low appropriateness designs. Caudate nucleus and putamen, areas related to the positive reward such as monetary acquisition showed greater activation in response to the designs of high appropriateness condition, compared to the low appropriateness designs.

  • Purpose: The study was performed to identify the process of change, decisional balance and self-efficacy corresponding to the stage of smoking cessation behavior based on Transtheoretical Model in industrial workers. Method: A convenience sample of 146 industrial workers except for the never smokers, were recruited at a H industry in Ulsan. Data were collected from February 1 to 28, 2002. The research instruments were Stages of Change of Smoking Cessation Measure(DiClemente et al, 1991), Process of change(Prochaska, 1988), Smoking Abstinence Self Efficacy (SASE: DiClemente et al, 1985) and Decisional balance(SDB; Kim, 1999). Result: The results of this study were as follows; 1. The subjects were distributed in each stage of smoking cessation change: There were 64 subjects (43.0%) in the precontemplation stage, 35 subjects(23.5%) in the contemplation stage, 28 subjects(18.8%) in the preparation stage, 14 subjects(10.1%) in the action stage and 7 subjects(4.7%) in the maintenance stage. 2. Analysis of variance showed that experiental process(F=2.808, p=.042), behavioral process (F=4.567, p=.004) self-efficacy(F=9.809, p=.000), pros(F=11.107, p=.000), cons(F=6.686, p=.000), pros- cons(F=3.446, p=.018) were significantly associated with the stages of smoking cessation change. 3. Through discriminant analysis, it was found that 'PROS' was the most influential variable in discriminating the four stages of change. Conclusion: This study can provide the basis of staged matching smoking cessation program using TTM for more effective and useful intervention.

  • Purpose: The purpose of this study was to measure home health resource utilization using a Case-Mix Adjustor Model developed in the U.S. Method: The subjects of this study were 484 patients who had received home health care more than 4 visits during a 60-day episode at 31 home health care institutions. Data on the 484 patients had to be merged onto a. 60-day payment segment. Based on the results, the researcher classified home health resource groups (HHRG). Result: The subjects were classified into 34 HHRGs in Korea. Home health resource utilization according to clinical severity was in order of Minimum (C0) < 'Low (Cl) < 'Moderate (C2) < 'High (C3), according to dependency in daily activities was in order of Minimum (F0) < 'High (F3) < 'Medium (F2) < 'Low (Fl) < 'Maximum (F4). Resource utilization by HHRGs was the highest 564,735 won in group C0F0S2 (clinical severity minimum, dependency in daily activity minimum, service utilization moderate), and the lowest 97,000 won in group C2F3S1, so the former was 5.82 times higher than the latter. Conclusion: Resource utilization in home health care has become an issue of concern due to rising costs for home health care. The results suggest the need for more analytical attention on the utilization and expenditures for home care using a Case-Mix Adjustor Model.

  • The purpose of this study was to evaluate the effects of heat treatment on mechanical properties in $0.016^{{\prime}{\prime}}{\times}0.022^{{\prime}{\prime}}$ blue Elgiloy wires and to measure the amounts of nickel and chromium released from the wires in artificial saliva. Ultimate tensile strength, yield strength and elongation were measured with universal testing machine (Instron). and the amounts of nickel and chromium released from the sample were measured with atomic absorption spectrophotometer after one week immersion in the artificial saliva. Ultimate tensile strength and yield strength were progressively increased below $1000^{\circ}F$, but elongation was decreased. And the results were reversed above $1100^{\circ}F$. After heat treatment of the sample for 9 minutes at $1000^{\circ}F$, the maximum tensile strength and yield strength were $213.6kg/mm^2$, $140.1kg/mm^2$, respectively. Both tensile strength and yield strength were decreased progressively above $1100^{\circ}F$. Elongation was appeared the minimum value (8.6%) after heat treatment for 9 minutes and 12 minutes at $1000^{\circ}F$. There was a pronounced increase in nickel and chromium liberation with increasing time and temperature. The maximum amounts of nickel and chromium released form the sample were $4.947{\mu}m/cm^2$, $3.088{\mu}g/cm^2$, respectively after heat treatment for 12 minutes at $1300^{\circ}F$. Heat treatment is applied to orthodontic wires, especially cobalt-chromium alloys, for the purpose of stress-relievning and hardening. When the heat-treatment of orthodontic wires, the heating procedure should be well controlled in order to have no effect on corrosion resistance and mechanical properties.

  • Synthesis of n-perfluorooctanesulfonyl fluoride(n-PFOSF), which is valuable precursor perfluoro-chemicals, was studied by electrochemical fluorination(ECF). Of prime concern was to investigate the cyclic voltamograms of Ni electrode in anhydrous hydrogen fluoride(AHF) with and without the reactants and to measure fluorine evolution potential. In a batch cell, chronoampherometric electrolysis and various chemical analysis such as GC, GC/MS and IR were used to understand the amphere change of electrode and the reaction paths. Fluorine equilibrium potential was found to be about 2.8V(vs. $Cu/CuF_2$) from the cyclic voltammograms and decay curves of anode potential in AHF. In batch processes, the ECF proceeded in two distinguished steps. The first step proceeded electrochemically and the second one chemically. Under 7V(vs. $Cu/CuF_2$), amount of crude products was proportional to the applied anode potential. Above 7V(vs. $Cu/CuF_2$), it had a hundred percentage with weight ratio of reactants and productivity of PFOSF was almost constant.

  • Purpose: This study was done to examine good death awareness, attitudes toward advance directives (ADs), and preference for care near the end-of-life (PCEOL) of hospitalized elders in long-term care hospitals. Relevant characteristics were investigated as well as correlation of the variables. Methods: This descriptive research study involved 161 hospitalized elderly patients in long-term care hospitals. A self-report questionnaire was used to measure Good Death Scale, ADs Survey, PCEOL Scale, and general characteristics. Collected data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation with SPSS/WIN 23.0. Results: In terms of good death awareness, a significant difference was observed; in according to age (F=3.35, p=.037), payer of treatment costs (F=3.98, p=.021), mobility (F=3.97, p=.021), heard discussion about ADs (t=-3.89, p<.001), and willing to complete ADs (t=2.12, p=.036). As far as attitudes toward ADs, the participants presented significant difference depending on religion (t=2.38, p=.018), average monthly income (F=3.91, p=.022), duration of hospital admission (F=5.33, p=.006), person to discuss ADs (t=-2.76, p=.006). On PCEOL, there was a significant difference, depending on religion (t=-3.59, p<.001) and perceived health status (F=3.93, p=.022). Finally, as for how the variables were related to each other, good death awareness and attitudes toward ADs had a weak positive correlation with PCEOL. Conclusion: To help seniors staying in nursing homes face a good death and enjoy autonomy, there should be educational and support systems that reflect each individual's sociodemographic characteristics so that the seniors can choose what kind of care they want to receive near the end-of-life.
