Effect of Intracameral Epinephrine and Indocyanine Green Use on Corneal Endothelium during Cataract Surgery

Purpose@#To investigate the safety of single and combined use of epinephrine and indocyanine green during cataract surgery by evaluating the effects on corneal endothelial cells. @*Methods@#From January 2017 to October 2021, 121 patients (132 eyes) who underwent cataract surgery were enrolled. Patients were divided into 4 groups: epinephrine (n = 20), indocyanine green (n = 49), epinephrine and indocyanine green combination (n = 12), and control (n = 51). Retrospective medical chart findings and endothelial cell count change data were compared among study groups before and after operation. @*Results@#Endothelial cell count change (△ECC) decreased for all groups; however, a significant difference among groups was not observed (p = 0.822). Univariate linear regression showed that △ECC was associated with postoperative hexagonality, nuclear sclerosis grade, ultrasound time, and cumulative dissipated energy (beta = -0.216, 0.254, 0.368, 0.351 and p = 0.013, p = 0.003, p < 0.001, p < 0.001). Multivariate linear regression showed that △ECC was associated with postoperative hexagonality and ultrasound time (beta = -0.215, 0.367, p = 0.010, p < 0.001). @*Conclusions@#Factors closely associated with postoperative endothelial cell loss were postoperative hexagonality and ultrasound time. No significant damage to the corneal endothelium was observed when epinephrine and indocyanine green were used alone or in combination. Thus, these agents appear safe for use in this context.

Development of a Resource-based Relative Value Scale and Its Conversion Factor for Advanced Nursing Practices in the National Health Insurance

PURPOSE: The purpose of this study was to develop a resource-based relative value scale (RBRVS) and its conversion factor for advanced nursing practices carried out by critical care nurse practitioners (CCNP) in intensive care units. METHODS: The methodology was developed by calculating CCNP's RBRVS for 32 advanced nursing services based on CCNP's workload and time spent in the context of national health insurance. A cost analysis was performed to estimate the conversion factor of CCNP's RBRVS. The share of CCNP's contribution to fee-for-service in intensive care units was also analyzed. RESULTS: Calculation of the RBRVS of 32 advanced nursing practices showed a range of points from 100.0 to 1,181.4 and an average of 296.1 points. The relevant conversion factor for advanced nursing practices in CCNP were estimated at 37.3-48.4 won. The contribution rate of CCNP's advanced nursing practices in the relative value scale of the national health insurance was estimated at 0.1-31.3%. CONCLUSION: Measuring the economic value of advanced nursing services will be a basis for esta-blishing a reimbursement system for CCNP's practices and thus encourage a social demand for advanced nurse practitioners.

Evaluating the NGC(TM) Evidence Based Guideline of Prompted Voiding for Use in Korea / 성인간호학회지

PURPOSE: The purpose of this study was to evaluate the applicability of the evidence based guideline for prompted voiding by Lyons & Specht (2001) in National Guideline Clearinghouse(TM) for use in Korea based on the experts' opinions. METHOD: The target expert group consisted of 8 registered nurses, 6 physicians, and 5 nursing professors who are experts in urinary incontinence. This study used a questionnaire survey. The appropriateness, applicability, and the present application of each recommendation in the guideline were analyzed with descriptive statistics using the SPSS program, with content analysis based on the experts' opinions. RESULT: The scores on each recommendation's appropriateness showed the high degree of agreement among nurses, physicians, and nursing professors. However, the recommendation for 'use of oxybutinin' showed the lowest score as 5.89. It was notable that the most recommendations scored lower for applicability compared with appropriateness. The reasons for lower scores for applicability were the lack of clinicians' knowledge of assessment and management, and the lack of resources in clinical settings in Korea. CONCLUSION: This study will augment the understanding of the actual urinary incontinence management in Korean clinical settings and can be used as the baseline data for further study of tailoring international guidelines into local and national clinical settings.

PURPOSE: The purpose of this study was to investigate gender role identity and health behavior and to explore the relationship between gender role identity and health behavior among university student. METHOD: Participants were 245 university students who lived in Daegu. Each participant was administered the KGRII (Korean Gender Role Identity Inventory), and Healthy Life Style: A self-test provided by ODDHP National Health Information Center. The collected data was analyzed using descriptive statistics, t-test, ANOVA, chi2-test with SPSS 11.0 PC Program. RESULT: 1. As a result of health behavior level, male students had more health risk behavior problems than female students in smoking(p=.00) and drinking (p=.03). Female students had more health risk behavior problems than male students in exercise and physical activity(p=.00). 2. For female students, feminity type (29.3%) was most common, subjects of undifferentiated type was 26.4%. For male students, masculinity type(32.4%) was most prevalent, and androgenic type was 31.4%. 3. Androginy typed group had more healthy behavior compared with other gender role identity typed group. In contrast, undifferentiated typed group had more high risk behavior compared with other typed group for all of health behavior. CONCLUSION: These results suggest that gender role identity is a stronger predictor of heath related variable than is sex of subject. Therefore effect methods to develop health promotion program should consider not only sex difference but gender role identity.

Female students were inclined to oppose traditional sex-role rather than male students. And the over 23 years old group tended to resist traditional sex-roles rather than other aged group. 3. The Androginy typed group had more progressive sex-role compared with undifferentiated typed group. CONCLUSION: These results suggest that gender role identity and sex stereotype were difference in sex and age. And the androgyny typed group had more progressive sex-role compared with other gender role identity typed group.

Needs Assessment for Information and Support of Parents of Children with Epilepsy / 기본간호학회지

PURPOSE: This study investigated the need for information and social support in parents of children with epilepsy. METHODS: A total of 119 parents of children with epilepsy were recruited and asked to fill out questionnaires. RESULTS: Of 119 parents, two-third reported that they received full and sufficient information about their child's disease and its management but one-third felt the information was insufficient and incomplete. Most parents (62.2%) felt at loss when their child had a seizure, either at home or at school. They wanted information on the causes of seizures, adequate steps deal with seizure and steps they should take to become adequate and supportive parents for their children. However, most parents were reluctant to disclose the disease or to receive support from outsiders. CONCLUSION: Regardless of the fact that most parents received sufficient information about the management of epilepsy, they felt at a loss when their child had a seizure attack. Therefore nurses should give specific instruction on seizure management and assess the needs of parents on a regular basis.

Changes in Student Nurses' Perception between Initial and Final Clinical Practice / 기본간호학회지

PURPOSE: The purpose of this study was to explore perception of clinical experience between the initial and final practice and to explore changes in the perception of clinical experience. METHODS: The study used a Q-method to measure perception of clinical practice. Thirty-six statements made up the finalized Q-sample. The P sample used thirty three nursing college students from K university. The initial collection was done in the first semester of their junior year and second collection was done in the last semester of their senior year. The Q-sorts by each student were coded and analysed with the Quanl PC program. RESULTS: Many students classified as having the perception type 'alienation of ideal and reality' or 'perception of limitation of ability' in the initial clinical practice changed to the type, 'active participation' by the final clinical practice. Further, in the initial clinical practice, part of 'active participation' and 'perception of limitation of ability' changed to 'alienation of ideal and reality'. CONCLUSION: This study shows that perception of their clinical practice by student nurses changed in a positive direction through clinical experience and that this fact was related to the level of satisfaction with nursing. The knowledge and understanding obtained in this research provide insights for nursing faculty and students involved in nursing education.

Development of a Korean Sexual Satisfaction Scale / 기본간호학회지

PURPOSE: The purpose of this study was to develop an instrument to measure sexual satisfaction in Korean adults. METHOD: Development of items for the instrument was done by a collecting, reorganizing, reducing and selecting process based on the literature. A total of 19 items were selected in this process. For evaluation of the appropriateness of the 19 items, questionnaires were given to an expert group consisting of 18 professionals (7 men and 11 women). Eighteen items having a response of 70% in 'very good' item or 'good' item were included as items for the instrument. With these 18 items, a 5 point Likert scale was developed, and reliability and validity tests of the scale were done. The subjects for the test were 1,127 Korean adults living in 11 areas in Korea. Data were collected from Dec. 1, 2000 to Feb. 28, 2001 and analyzed with SPSS/PC+ 10.0 program. Item analysis and factor analysis were used to assess the reliability and validity of the scale. Chronbach alpha and corrected item-total correlation were obtained to verify internal consistency, and principal component analysis with the varimax rotation was used to identify structure validity of the developed tool. RESULT: Reliability of the scale was .9503 and corrected item-total correlations of the items were distributed from .5208 to .7899. As a result of the factor analysis, the items were categorized into three factors. The cumulative variance of the three factors was 67.1%, and all of the variances of the factors were above 5%. Because factor 1 (8 items) indicated a special feeling of psychological satisfaction with sexual activity, it was named 'psychological factor'. Factor 2 (8 items) indicated a feeling of satisfaction in the interaction with sexual partner through communication and variation, therefore it was named 'interactional factor'. Factor 3 (2 items) was about the frequency and duration of sexual intercourse and indicated physical dimensions of satisfaction, so it was named 'physical factor'. The average score for sexual satisfaction of the 1,127 subjects was 65.32 (+/-12.71), and histogram of the score showed a normal distribution with skewness -.425. CONCLUSION: Finally, a Korean Sexual Satisfaction Scale(KSSS) was accepted as a 5 point Likert scale with 18 items after the statistical test for reliability and validity. In conclusion, KSSS is a useful instrument which is valid and reliable can be used to understand the sexuality of Korean adults.

A Study on Serum Ferrum, TIBC, and Ferritin's Circadian Rhythm in Normal Adults / 기본간호학회지

PURPOSE: The purpose of this study was to identify characteristics of serum ferrum, TIBC and ferritin's circadian rhythm in normal adults and to prepare a standard to determine the examination material extraction time. METHOD: Nine women and ten men made up the convenience sample for this study. they were from the staff of D university hospital and students in D medical School located in K city who met the qualifications for inclusion in the sample. The value of serum ferrum, TIBC and circadian rhythm were calculated as follows; First, each variable's amplitude, the acrophase and average were measured for a 24 hour cycle using the cosinor method, and then each person's rhythm was analyzed. RESULTS: There were significant serum iron circadian rhythm for both men and women (p<.05). For the men, mesor was 105.91 microgram/dl, amplitude was 29.52 microgram/dl, and the acrophase was 9.76 hour. For the women, mesor was 108.17 microgram/dl, amplitude was 28.09 microgram/dl, and the acrophase was 11.42 hour. The rhythm change of TIBC was only significant for the women (p<.05), mesor was 383.39 mg/dl, amplitude was 60.29 mg/dl, and the acrophase was 14.93hour. As for the circadian rhythm of the ferritin, there are no diurnal variation in either sex, men were between 134.0 ng/ml and 137.4 ng/ml, and women, between 29.1 ng/ml and 30.1 ng/ml. CONCLUSION: To help diagnose the boundary line between normal or deficiency in iron, measurement should be carried out at a fixed time in the morning and evening, or a more proper time would be in the afternoon at the time when the width of amplitude is the least.

Development of Korean Gender Role Identity Inventory / 간호학회지

PURPOSE: This study was performed to develope a scale of gender role identity in Korean adults based on the Bem's theory of androgyny. Although there were several tools in Korea, they were revealed having some problems of cultural differences, translation biases, and methodological problems. METHODS: A list of 78 items were developed using the existing tools and descriptions from 5 married couples. The items were the typical personality characteristics which were manifested by gender, male or female. And the list contained several items which were the socially desirable personality characteristics. which would be simply used as contextual items. Validity of the 78 items were screened by 18 expert panels with 4 point Likert scale, and 57 items were judged as highly valid from 70% of the experts, which were selected as preliminary items for the tool. Using the preliminary tool which was developed as a 4 point Likert scale, data were collected from 1,127 subjects for item analysis and factor analysis. 53 items were remained, because 4 items whose item-total correlation were lower than 0.2 were excluded by the result of item analysis. Factor analysis was done with the 53 items, and 49 items whose factor loadings were same and higher than 0.4 were remained. 3 factors were identified with eigen value 2.0, and these factors were named as masculinity, femininity, and social desirability. RESULTS AND CONCLUSION: KGRII(Korean Gender Role Identity Inventory) which contained 45 items was developed, with 15 items for 3 factors. The reliability of the tool was very high. Cronbach alpha of the tool was 0.929, and alpha of the subscales were ranged from 0.841 to 0.922.
