  • The purpose of this study is to assess the suitability of the statistical techniques employed in papers published in the Korean Journal of Veterinary Research from March 1997 to March 1999 and it is hoped that the critical assessment may be of help to other researchers preparing their works for publication. Of the 246 original papers 94 were included in the analysis. Of 62 papers with the measure of central location and dispersion of data 34 (54.8%) used them correctly : 9 (39.1%) of 23 for t-test ; 1 (33.3%) of 3 for correlation analysis ; 7 (43.8%) of 16 for analysis of variance (ANOVA) ; 5 (62.5%) of 8 for chi-square test ; 44 (71%) of 62 for description of p-value. A number of papers employed ANOVA did not perform subsequent analysis of multiple comparison. Compared to the results of others, relatively higher proportion of papers in the present study was evaluated as appropriate analysis. The reason is that papers described insufficiently on the study design were not included, and evaluation items were restricted to the cases violated seriously inherent assumptions for each statistical technique. Statistical misuse or abuse appeared in the study is due to lack of knowledge on statistics and short of its importance for improvement the quality of paper. Because an inappropriate analysis can lead the readers to misunderstand on findings, observed statistical analyses must be valid, and correctly undertaken. It is suggested that more intensive statistical refereeing are needed, and the communication should be allowed for the controversial points.

  • This study is a cross-sectional survey study aimed at collecting basic data for the development of a program to cultivate a positive attitude toward dementia among people caring for dementia patients. For this study, data were collected from March 1 to March 7, 2022 as a structured questionnaire, and 232 study participants were in their 20s to 60s. The collected data were derived from chi-square test, t-test, and simple regression analysis using the spss 18.0 program. As a result of the analysis, women had higher treatment knowledge for dementia than men, men had higher attitudes toward dementia than women (p<0.01), and people living with dementia patients had higher attitudes than those who gave birth (p<0.01). Attitudes toward dementia were more positive in the family than those with dementia patients (p<0.01). Dementia-related knowledge consists of disease knowledge, treatment knowledge, and nursing knowledge, of which only positive dementia attitude affects dementia treatment knowledge (t=5.29, p<0.01). Based on these results, it is suggested that the provision of accurate knowledge about dementia treatment should be planned first as a nursing program for dementia patients.

  • Purpose: This study aimed to develop an educational program on nursing records especially focused on legal issues, and to test the effects of the educational program on nurses' knowledge, performance, and behavior. Methods: A textbook on legal issue-focused nursing records and an instrument with 36 items rated on a 5-point scale (1-5) for measuring the nurses' charting-related performance and behavior were developed from November 2007 through March 2008. A nonequivalent control group pretest-posttest design was employed to test the effects of the education program. Knowledge was self-reported by the Nurse Charting Knowledge Scale, while performance and behavior were measured by their nurse managers. The pretest and posttest were conducted from March through May in 2008. A total of 226 Korean nurses participated in this study. Data were analyzed with descriptive statistics, t-test, Chi-square, paired t-test, Spearman's coefficient, and multiple regression. Results: Nurses who received the intervention showed greater levels of knowledge (t=10.28, p<.001), performance (t=2.53, p=.013), and behavior scores (t=3.07, p=.002) than those of the control group. The factors influencing the improvement of knowledge were 'job attitude' (t=-3.32, p=.001) and 'career in present unit' (t=2.95, p=.004). The factor influencing the improvement of performance was 'career in present unit' (t=-3.39, p=.001). The factor influencing the improvement of behavior was 'job attitude' (t=-3.46, p=.001). Conclusion: The educational program on legal issue-focused nursing records was effective in improving nurse charting-related knowledge, performance, and behavior.

  • We have proposed BIST method and circuit for embedded 16M SDRAM with logic. It can test the AC parameter of embedded 16M SDRAM using the BIST circuit capable of detecting the address of a fail cell installed in an Merged Memory with Logic(MML). It generates the information of repair for redundancy circuit. The function and AC parameter of the embedded memory can also be tested using the proposed BIST method. It is possible to test the embedded SDRAM without external test pin. The total gate of the BIST circuit is approximately 4,500 in the case of synthesizing by 0.25μm cell library and is verified by Verilog simulation. The test time of each one AC parameter is about 200ms using 2Y-March 14n algorithm.

  • Objective: The study was planned with the purpose of examining the attitude of women who have pap-smear test for the early diagnosis of cervical cancer, factors affecting their decisions and their feelings and experiences during this period. Materials and Methods: A phenomenological method was used. Data were collected between March 2012 and April 2012 using standard and purposive samplings from 17 women. A detailed interview with women were held in their houses and recorded. The data collection tool consisted of two parts, one of which is information form with 17 questions identifying sociodemographic and cervical cancer risk factors of women and the second part is made up of semi-structured interview form with 15 alternative questions taking literature and the pap-smear test into consideration. Collected data were put into a written document. Content analysis was held by loading the documents into NVIVO 8 Statistical Programme. Results: The study comprised themes such as cervical risk factor, decision of taking pap-smear test, taking pap-smear test, knowledge about pap-smear test, relieving factors during pap-smear test, obstructive factors during pap-smear test, gynecological examination and feelings of women during and after pap-smear test while waiting for the results. Conclusions: As women perceive gynaecological examinations differently from other examinations, they have different feelings in each process of the Pap smear test. Medical staff should advise women more clearly on the nature and advantages of the Pap-smear test.
