N/A Background: Magnetocardiogram (MCG), which records the changes of magnetic fields generated by the heart`s electrical activity, theoritically can provide unique data for clinical application. To date, MCG has been investigated only at a single time point after myocardial infarction (MI) with severe left ventricular dysfunction in rats. The purpose of the present study was to investigate sequential changes of MCG after MI and to evaluate effects of infarct size on MCG. Methods: Acute MI were induced by the permanent ligation of left coronary artery in 22 rats. Magnetic fields were recorded just above a rat with Nb Superconducting Quantum Interference Device (SQUID) gradiometer inside a magnetically shielded room. MCG was measured before and immediately after surgery and it was subsequently recorded at the time points of 1, 4 and 6 hours post operatively. MCG was also measured at 1, 3, 7 and 21 days after surgery. Results: Elevation of ST segment and appearance of pathological Q wave on the MCG were evident immediately after the ligation of coronary artery and persisted to 6 hours after MI. On MCG, ST segment was depressed and T wave was inverted from 1 day after MI. In rats with small-and moderate- sized MI (infarct size〈30%), ST depression returned to near the isoelectric level and Q wave disappeared from 7 days after MI. However, ST depression and Q wave were still present in rats with larger infarct (infarct size≥30%). Conclusion: Evolutional changes of MCG were well-recognized up to 21 days after MI. Furthermore, the infarct size can be expressed by the extent of Q wave and ST segment depression on MCG. Taken together, these data indicate that MCG is a helpful modality for the diagnosis, evaluation of infarct size and follow up after MI.(Korean J Med 62:42-48, 2002)

This study attempted to provide a spectrum analysis for quantitative evaluation of singing voice quality of singing students rather than the presence or absence of the singer's formant. The regression analysis was used to analyse the relationship between ringing quality, SPR, and SPP of singing voice of college student subjects majoring in music. This study measured singing power ratio (SPR) in 41 singing students. Digital audio recordings were made in sung vowels for acoustic analyses. Each sample was judged by 1 experienced singing teacher and 4 voice pathologists on one semantic bipolar 7-point scales (ringing-dull). The results showed that the SPR and SPP had significant correlations with ringing Quality. The SPR had a significant relationship with ringing quality on singing voice in singing students. The SPR can be an important quantitative measurement for evaluating singing voice quality.

Background and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

Purpose: The Purpose of this study was to explain the effects of aromatherapy massage on the preoperative anxiety of hemorrhoidectomy patients, and to provide the effective and holistic nursing care to them. Method: The research design was a nonequivalent control group non-synchronized design. The data were collected during the period from November 1 to November 30, 2003 at K-Hospital in Seoul. The subjects were fifty patients who were to have a hemorrhoidectomy under general anesthesia. They were assigned to two groups, 25 subjects to the experimental group and 25 subjects to the control group. The State Anxiety Inventory tool was used to measure state-anxiety on all patients the day before surgery. Systolic and diastolic blood pressure, and pulse rate were measured on the day before surgery and the preoperative period. The experimental group received aromatherapy massage on the hand with lavender oil. Data were analyzed by x^(2) test, independent t-test, paired t-test. Result: 1. Hypothesis 1, that the level of preoperative state-anxiety of the experimental group who received aromatherapy massage would be lower than that of the control group who did not received aromatherapy was supported(p=.047). 2. Hypothesis 2was that the Physiological index of the preoperative anxiety of the experimental group who received aromatherapy would be lower than that of the control group who did not received aromatherapy. The 1st subhypothesis that "the level of the preoperative systolic and diastolic blood pressure of the experimental group would be less than that of the control group" was not supported. Conclusion: Aromatherapy massage can be regarded as a partially effective nursing intervention that relives the preoperative anxiety of surgical patients and stabilizes vital signs.

In D. melanogaster, evidence of frequency-dependent selection has been observed at two loci Adh and α-Gpd. From the both loci the gene frequency changes were carried out between inversion free genotypes at two gene frequency levels (F alleles=20%, 80%). Allele frequency changes were recorded for a period of 11 generations. Genes at both Adh and α-Gpd loci second chromosome were scored by agarose electrophoresis. When homozygote (either FF or SS) was persent in low frequency(20%), its fitness was enhanced, but when the frequency is high(80%, its fitness was reduced. This may idea to a stable polymorism because a generation increases as its frequency decreases. The allelic frequency of Adh approached an equilibrium after 11 generations, converging toward the frequency (case A_1=76%, cage A_2=69%). However, the possibility remains that Adh alleles in nature are associated with alleles at closely linked loci. If linkage disequilbrium is present in the experiments because it exists in nature, then observed effects (frequency-dependent selection) would affect the Adh locus in nature as well. The frequency of α-Gpd approached an equilibrium, converging toward the frequency (cage B_1=40%, cage B_2=33%).

This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

Purpose: The purpose of this study was to identify and compare role conflict and job satisfaction between nurses in ICU and nurses in general ward. Method: The subjects of this study consisted of 141 nurses employed at ICU and 201 nurses employed at general ward, who were recruited from 5 university hospitals with 500 beds located in Seoul and Gyeonggido. The instruments included role conflict scale developed by Kim and Park(1995) and job satisfaction scale translated and modified by Lee(1996). The collected data were analyzed using the SPSS WIN 10.0 program for descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. Result: In the two groups, there was a inverse correlation between role conflict and job satisfaction. In ICU, nurses' role conflict levels differed significantly depending on religion(p<.05), total experience(p<.05), scheduled to work as a nurse(p<.05). And nurses' job satisfaction levels differed significantly depending on total experience(p<.05), working period in current post(p<.001), scheduled to work as a nurse(p<.001), motive of choosing the nursing science(p<.01), and job satisfaction(p<.001). In general ward, nurses' job satisfaction levels differed significantly depending on marital status(p<.05), educational 1eve1(p<.01), total experience(p<.001), motive of choosing the nursing science(p<.01), and job satisfaction(p<.001). Conclusion: Summing up, the nurses at ICU showed higher level of role conflict than the nurses ay general ward. Therefore, it is needed to decrease the level of nurse's role conflict and improve their job satisfaction in ICU.

Purpose: This study was undertaken in order to examine relations of eating disorders, health locus of control of college women, and to determine factors affecting eating disorders of college women. Method: The subjects were 282 students at a university in Busan. The instrument used for this study was a questionnaire on general characteristics, eating disorders (24 items), health locus of control (11 item) and self-esteem (10 item). Data were analyzed using means, percentages, t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression with a SPSS WIN 11.0 program. Result : Depending on BMI, there was no obese subject, 62.0% of the subjects were underweight, and 37.9% were normal. Over 40% of the subjects perceived them to be overweight while 62.1% of the women were underweight as defined by BMI. The total mean score of anorexia was higher than bulimia nervosa. There were significant differences in eating disorders according to BMI, perceived view of appearance, body satisfaction, experienced weight-control, and predictors of weight control method. Eating disorders showed a significant negative correlation with health locus of control and self-esteem. Stepwise multiple regression analysis revealed that the most powerful predictor of eating disorders was BMI. Experienced weight control, health locus of control and self-esteem and body appearance had significant effects on eating disorders. There predictive variables of eating disorders explained 27% of variance. Conclusion: The result of this study showed that eating behaviors among college women developed into eating disorders or were seriously disturbed. Therefore, to prevent eating disorders, health education should be provided to college women in relation to eating behaviors for health management.

Purpose : The purpose of this study was to identify the factor to choice hospital and image of nursing services in outpatients. Method : The subjects were 142 outpatients of the three general hospitals with more than 450 beds. The data was collected using structured questionnaires from May 14, to June 1, 2005. The data was analyzed by the SPSS(ver 1O.0)program, and it included descriptive statistics, and cross tabulation. Result : The rank of construct factors hospital choice which were thought important by subjects was the first 'convenience facilities', the second 'thrust to physician', the third 'kindness of nurse and staff'. The rank of construct factors nursing service image which were thought important by subjects was the first 'kindness', the second 'neat feature', the third 'accuracy', the fourth 'responsibility'. As for the analysis that the nursing service image affected the choice of hospital, 'It affected the choice the hospital' took 87.3%, and it was higher than the 22.7% as 'It did not affected the choice the hospital'. Conclusion : These results suggested that to recognize the merits and demerits of hospitals and to develop their original service area are very important. therefore, these findings give useful information for constructing an effective marketing strategies in hospitals.
