This study attempted to verify the effect of SBAR-based simulation practice on reporting confidence, communicative competence, nursing competence and debriefing satisfaction of nursing students. This study included 46 students who took the simulation practice course for third-year nursing students at one universities located in one region, The data were collected from October 30 to December 22, 2023 using a self-report questionnaire before and after simulation practice, and is a one group pretest-posttest design study. Data analysis was performed using SPSS/WIN version 26.0 program using frequency analysis, descriptive statistics, Shapiro-Wilk test, and Paired t-test. As a result of the study, the average of the reporting confidence was 5.79±1.47 before the training and 7.13±1.56 after the training, the communicative competence was 3.62±0.44 before the training and the average after the training was 4.34±0.67, the nursing competence was 2.64±0.39 before the training and 3.26±0.51 after the training, and the debriefing satisfaction was 3.57±0.51 before the training and 4.18±0.58 after the training. There was a statistically significant difference in reporting confidence(t=2.84, p=.006), communicative competence(t=-3.28, p=.001), nursing competence(t=-8.16, p<.001), debriefing satisfaction(t=2.72, p<.001) before and after SBAR-based simulation practice. Based on the results of this study, it is thought that communication education using SBAR to nursing students should be systematically carried out from the lower grade curriculum, and it is necessary to strengthen and expand reporting education using SBAR communication in various practice situations as well as simulation practical education to improve nursing competency.

A total of 193 children between three and six years of age were given tests by using the PRES, REVT, KOSECT, and APAC. A specificity between referred and non-referred cases was not high. In the current study, the sensitivity of formal tests was insufficient. But combining of parental report with formal language tests could provide good criteria for identifying language impairment. The CCC-2 may provide an effective means to identify language difficulties using a standardized approach.

우울증은 동기, 의욕, 관심, 주의력, 정신기능 및 식욕의 감소를 특징으로 하는 일종의 기분 장애이다. 우울증은 유전적, 내분비 및 환경적 스트레스를 포함한 다양한 원인에 의해 발생하지만 가벼운 우울증은 식이요법으로 개선되는 것으로 보고되었다. 따라서 우울증 환자를 치료하기 위해서는 기능성 및 영양 보충제를 포함한 다양한 식품 공급원이 필요하다. 치즈에는 숙주 건강에 유익한 영향을 미치는 생리 활성 펩타이드가 포함되어 있다. 특히 저지(Jersey) 우유는 홀스타인(Holstein) 우유보다 고형분 함량이 높은 것으로 보고되었다. 이 연구는 저지(Jersey) 와 홀스타인(Holstein) 우유의 가우다 치즈(Gouda cheese)가 만성 스트레스(CUMS, chronic unpredictable mild stress)에 미치는 영향을 조사했다. 치즈를 먹인 만성 스트레스 마우스 모델의 개선적 변화는 젖소 종에 관계없이 통계적으로 유의미하게 효과적으로 나타났다. 흥미롭게도 PCR을 통한 분변 미생물 균총 분석에서 저지 치즈를 섭취함으로써 Bacteroidetes가 증가하고 Firmicutes가 유의적으로 감소하는 것으로 나타났다. 종합하면, 본 연구는 치즈 섭취가 스트레스 개선 작용이 있음을 제시하며, 특히 장내 미생물 균총의 유익한 방향으로의 변화가 관찰되는데, 치즈의 생리활성물질 혹은 장내미생물 균총의 대사물질들이 이러한 행동·정신학적 개선 작용과의 연관성이 있음을 시사한다.

Purpose: Use of inappropriate statistical methods may lead to incorrect conclusions and a waste of valuable resources. The goal of this study was to assess the frequency and the types of several common statistical errors in the published articles of the Journal of the Korean Academy of Prosthodontics (JKAP) for a 5-year period. Materials and methods: Of 336 articles in the JKAP published from 2006 to 2010, 255 articles using statistics were reviewed and classified by statistical method and year. The frequency and types of the statistical methods were examined, and the statistical errors were evaluated by the appropriateness of the experimental design, assumption check, independent outcomes, proper sample size and suitable use of statistical method. Statistical guidelines were completed based on the appropriateness. Results: Of the 255 articles using statistics, 193 articles (75.9%) used inferential statistics and 153 articles used SPSS statistical software (60.0%). Of the articles using inferential statistics, the three most frequently used statistical methods were ANOVA (41.5%), t-test (20.0%), and the nonparametric method (16.9%). The average rate of statistical errors was 61.2 percent, similar to the rate reported by several studies completed for the medical journal. Conclusion: After the whole analysis of the difference among the groups, post-hoc tests for the pairwise comparisons are required. The optimal sample size calculation is an essential part of this study protocol. To minimize the occurrence of statistical errors, statistical guidelines were developed according to each statistical test procedure and will contribute to the academic improvement in the JKAP.

Objectives: The purpose of this study was to estimate the safety and efficacy of a mandibular advancement device (MAD), 'Bioguard,' for the treatment of obstructive sleep apnea (OSA). Methods: In this 5-week prospective, multi-center, single group, and non-inferiority trial, patients who chose 'Bioguard' as their treatment option were evaluated using both questionnaires (Pittsburgh Sleep Quality Index (PSQI), Epworth sleepiness scale (ESS)) and polysomonography (PSG) (apnea hypopnea index (AHI), oxygen saturation). All patient data, including clinical records, PSG studies (both pre- and post-treatment), and adverse events (AEs), were reviewed and analyzed. Results: Results were obtained for 59 of 62 patients (95.16%). No significant difference in success rate was found between the MAD treatment and surgical treatment (95% CI). AHI, PSQI, ESS and oxygen saturation demonstrated significant improvement (p < 0.001) after MAD treatment, and 39 of 62 patients (62.9%) reported 85 AEs. 79 of the 85 AEs (91.8%) were mild cases, and there were no severe AEs related to the MAD treatment. Conclusion: The MAD 'Bioguard' should be considered as an alternative treatment option for OSA patients.

Objectives: Antidepressants are frequently associated with sexual dysfunction. Especially, there were few report of sexual dysfunction related with venlafaxine and mirtazapine in Korea. The purpose of this survey was to evaluate the frequency and nature of sexual dysfunction related with selective serotonin reuptake inhibitors(SSRIs), venlafaxine and mirtazapine by the use of specific questionaires. Methods: In one hundred twenty two patients, sexual dysfunction was investigated cross-sectionally by using The questionaires for sexual dysfunction, which includes questions about decreased libido, delayed orgasm or ejaculation, premature ejaculation or orgasm, absence of orgasm or ejaculation, erectile dysfunction in men/vaginal lubrication dysfunction in women, sexual pain and patient's tolerance of the sexual dysfunction. BDI was also measured. Sexual dysfunction was analyzed in association with the duration and the dose of medications and the severity of depression. Results: The incidence of sexual dysfunction during antidepressants use in our survey was 37.7%. There were no difference of incidence in sexes(p=.746). In comparison of paroxetine, venlafaxine and mirtazapine, there were no significant differences of the incidence(p=.065) and the severity of any type of sexual dysfunction. Conclusion: Although there were no significant differences of sexual dysfunction in our survey, sexual dysfunction may be closely associated with antidepressants. Further prospective study of sexual dysfunction should be needed.

Simultaneous equation models, increasingly used in many detailed analyses, tend to get larger and more sophisticated to describe the structure of the study area to be close to the actual situations. In setting up such a system of equations, statistical results and simulation performance of the model as a whole may be meaningless and unrepresentative of the real world due to a structural instability that is built into the model when the equations are combined and solved simultaneously. Even though the use and subsequent analysis of an unstable system are likely to mislead us, most of the studies that take the simultaneous equation approaches neglect such a serious problem. Thus it is necessary to illustrate how to check the stability problem and apply to the actual model, then investigate how such as analysis is able to provide useful information about the structural characteristics of the model from the dynamic viewpoint.
