OBJECTIVE: Currently, preparation for childbirth is becoming an increasingly popular addition to patient education. Because of this interest, it seems advisable to review the evidence on the effect of prepared childbirth. The objective of this study is to evaluate the effectiveness of Lamaze preparation on labor and delivery. METHODS: To investigate whether prepared-childbirth courses offer measurable physical advantages, we compared the labor and delivery characteristics of 80 primiparas who had taken Lamaze-training classes with 76 control patients who had not. We reviewed retrospectively obstetrical records of 156 pregnant women delivered in Ewha Womans University MokDong Hospital from January to December, 1997. RESULT: The length of the first stage of labor in the group that attended childbirth preparation classes was 5.70 hours and 6.93 hours in the comparison group. This difference was statistically significant (P= .040). The mean duration of the second stage of labor in attenders was 42.43 minutes and 41.16 minutes in the nonattenders(P= .719). Average duration of labor in attenders was 1.07 hours shorter than in nonattenders (P= .075). The cesarean section rate in attenders was 25% compared with 36.8% in nonattenders (P= .10920). CONCLUSION: No statistical significance was found in this study. However we need to be aware that the length of first stage of labor was shorter and the rate of cesarean section was lower in prepared group. Childbirth education should be integrated into prenatal health care to be readily available for all women.

Hand washing is an important component of hygiene program for food handlers. Hands can be a source of direct or indirect contamination of foods with pathogenic microorganisms. In this study, the effectiveness of hand washing methods and the use of 70% alcohol solution against transient skin bacteria was tested in an university foodservice facility. 70% alcohol solution is sprayed for 5 seconds automatically when hands are placed in the dispenser. Samples were taken using swab technique in meat cutting area, vegetable trimming area, and vegetable cutting area: before and after washing hands according to planned methods, and after being sprayed with 70% alcohol solution after washing hands. The bacteriological analysis of total plate counts, coliform, fecal coliform of food handlers' hands was done. Statistical data analysis was completed with Mann-Whitney U test and Kruskal-Wallis model using the SPSS program. The levels of initial contamination of workers' hand were significantly different by the work areas(chi-square=9.156, p<0.01). Workers in the vegetable trimming area had more heavily soiled hands than in the other work areas. Mean of TPC counts and coliform was 8.97x10(5) CFU/12.4cm2, 2.93x10(2) MPN/12.4cm2 respectively, but fecal coliform was not detected. Transient bacteria were removed from hands after washing and using 70% alcohol solution but were not removed completely. Mean reduction percentage in TPC varied among work areas and ranged from 93.19% to 94.99%, and in colifroms from 97.31% to 100%. A significant difference in TPC was found between before and after hand disinfection (Z=-2.714, p<.01) and between standardized hand washing procedures and un-standardized hand washing procedures(z=-2.301, p<.01). Subjects using the hand sanitizer showed a great elimination of TPC(99.45% reduction), but this effect was valid only after following proper washing procedures. Based on the results, the most effective hand washing method was recommended as the combination of the standardized hand washing procedure with warm-water and use of th 70% alcohol solution. The results can be used to develop hand hygiene programs and training strategies for enhancing hand hygiene practices for food handlers in foodservice operations.

PURPOSE: Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. METHODS: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. RESULTS: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. CONCLUSION: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

Purpose: The purpose of this study was to investigate the trends in domestic and foreign studies on the various effects of parental phubbing behavior on adolescent children. Methods: This scoping review was conducted according to the Joanna Briggs Institute (JBI) protocol. Literature published in five foreign databases and four domestic databases was searched. Two researchers independently reviewed and selected the literature, and the extracted data included the author, publication year, country of study, research methodology, study participants, independent variables and tools used, dependent variables, and influencing factors. Results: A total of 575 articles were identified, and 43 articles were finally included in the analysis. The publication years ranged from 2018 to 2022, and most studies were cross-sectional studies. The dependent variables were broadly classified into cognitive-behavioral, psychological, and social variables, with smartphone addiction and depression being the most commonly reported. Conclusion This study represents a significant attempt to investigate the trends in domestic and foreign research on the effects of parental phubbing on adolescent children, and is expected to be utilized as a foundation for developing programs to promote mental health, including interpersonal relationships for adolescents.

PURPOSE: The purpose of this study was to compare the nursing activities delineated by interview of nurses with those on nursing notes. METHOD: The participants of interview were 18 nurses working in medical and surgical units of a large hospital in Seoul. Each nurse was asked to choose one patient who demand most nursing care among her patients. The nurse was then interviewed to describe what her nursing activities for the patient was that day. The audio-taped interview was transcribed and the content was analyzed by researchers. Nursing notes of each nurses' patients were copied and the content analyzed by researchers. Finally, themes from the interview data and those from nursing notes were compared. RESULT: Activities related to emotional or psychological nursing, education for patient and families, and problem solving related to treatment or nursing procedure were most often omitted in nursing notes. Most of the documentation in nursing notes were related to physical condition of patients or physician's orders. Nurses described that they will do better recording if they were given less patient care responsibility, had better nursing knowledge, had better recording system, and received more training on nursing record. CONCLUSION: Nursing notes did not reflect nursing activities properly. Few independent nursing roles were documented in the nursing notes. Development of nursing education program and nursing record system is needed for improvement of nursing record.

Follicle stmulating hormone ( FSH ) consist of alpha and beta subunits, which are encoded by se-parate genes. Pituitary release of FSH appears to be regulated by the hypothalamic GnRH and the gonadal steroid hormones. In addition, inhibin and follistatin produced by the gonad have been known to inhibit FSH secretion selectively. However, little is known about their regulation of the biosynthesis of FSH subunits at transcriptional and posttranscriptional levels. In the pre-sent study, we studied the time course of changes in alpha and FSH beta subunit mRNA concentrati-ons after castration and the effects of ovarian steroids of changes in alpha and FSH beta subunit mRNA concentrations after castration and the effects of ovarian steroids on alpha and FSH beta subunit mRNA in ovariectomized rats in order to determine Whether FSH subunit synthesis is modulated at the pretranslational levels, and whether synthesis and secretion are differently regulated. Results are as follows : 1. The time course of the rise in the steady state alpha subunit and FSH beta subunit mRNA levels were observed after ovariectomy, which paralleled the increases in serum and pituitary FSH concentrations. The time course experiments revealed differences in the patterns of alpha and FSH beta subunit mRNA responses, the rise in FSH beta subunit mRNA levels being more pro- minent than the rise in alpha subunit mRNA. 2. FSH beta mRNA levels were negatively regulated by the single injection of progesterone but not by estradiol, suggesting that FSH beta subunit mRNA seemed to be more sensitive to ne-gative feedback by progesterone than estradiol. Similar results were obtained by the continuous treatment of ovarian steroids for 1~4 days, but inhibition was more prominent with continuous treatment. It is, therefore, concluded that estradiol and progesterone inhibit the synthesis of FSH at the pretranslational level by modulating the steady state levels of alpha and FSH beta subunit mRNA, progesterone effect being more promiment than that of estradiol and alpha and FSH beta subunit are regulated in a different manner.
