Purpose: The purpose of this study is to analyze the current status of disasters and initial first aid in the construction industry, and to suggest the deployment of emergency medical technicians and reinforcement of first aid training in the construction industry. Methods: Among industrial accidents in 2020, the accident characteristics and initial first aid that occurred at construction sites were analyzed, and the emergency dispatch of 119 paramedics was analyzed through the SPSS method. Results: The incidence of serious accidents was high at small and medium-sized construction sites with less than 50 workers, and the incidence of falls was high, and there were few first responders who could provide first aid in the beginning. Therefore, it is necessary to improve first aid response capabilities at small construction sites. Conclusion: In order to improve the ability to respond to first aid at construction sites, it is necessary to deploy first responders and strengthen first aid education.

Objective: The purpose of this retrospective study was to evaluate the appropriateness of various follicle-stimulating hormone (FSH) starting doses in expected normal responders based on the nomogram developed by La Marca et al. Methods: A total of 117 first in vitro fertilization cycles performed from 2011 to 2017 were selected. All women were expected normal responders and used a recombinant FSH and flexible gonadotropin-releasing hormone antagonist protocol. The FSH starting dose was empirically determined (150, 225, or 300 IU). The FSH starting dose indicated by La Marca's nomogram was determined using female age and serum $anti-M{\ddot{u}}llerian$ hormone or basal FSH levels. If the administered dose was exactly the same as the proposed dose, the cycle was assigned to the concordant group (34 cycles). If not, it was assigned to the discordant group (83 cycles). Optimal ovarian response was defined as a total of 8-14 oocytes, hypo-response as < 8 oocytes, and hyper-response as > 14 oocytes. Results: Between the concordant and discordant group, ovarian response (optimal, 32.4% vs. 27.7%; hypo-response, 55.9% vs. 54.2%; and hyper-response, 11.8% vs. 18.1%) and the number of total or mature oocytes were similar. Ovarian hyperstimulation syndrome was rare in both groups (0% vs. 1.2%). The implantation rate, clinical pregnancy rate, miscarriage rate, and live birth rate were all similar. Conclusion: The use of the proposed FSH starting dose determined using La Marca's nomogram did not enhance the optimal ovarian response rate or pregnancy rate in expected normal responders. Individualization of the FSH starting dose by La Marca's nomogram appears to have no distinct advantages over empiric choice of the dose in expected normal responders.

Objective: The increasing number of people living in high-rise apartments may result in a delayed response from emergency medical technicians called out for an out-of-hospital cardiac arrest, making the role of apartment managers as the first responders extremely important. This study investigated whether automated external defibrillator (AED) placement influences the willingness of apartment managers to perform cardiopulmonary resuscitation (CPR) and use an AED. Methods: A cross-sectional target population-based survey was conducted in Daegu, July 2016. Questionnaires were sent to apartment managers working in apartments with more than 500 households. The general characteristics of the respondents, status of CPR education, and knowledge about and willingness to perform CPR and use an AED were investigated. Results: Of the 1,445 respondents, 758 (52.5%) worked in apartments with AEDs, of which 77.8% and 70.8% were willing to perform CPR and use an AED, respectively, compared with 68.1% and 60.0% of respondents who worked in apartments without AEDs. After adjusting for potential confounders, AED placement was associated with the willingness to perform CPR (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04-1.71) and use an AED (OR, 1.39; 95% CI, 1.10-1.75). Prior CPR training and accurate knowledge of CPR skills were also associated with the willingness to perform CPR and use an AED. Conclusion: Placing AEDs in high-rise apartment buildings and providing refresher CPR education for maintaining CPR skills will be necessary to support apartment managers in their role as first responders.

디지털 증거를 다루는 범죄 사건 수사가 증가함에 따라 초동조치를 할 수 있는 인력과 개선된 수사절차 모델의 필요성이 증가하고 있다. 최근 들어 디지털 포렌식 분류(triage)와 예비분석 등의 개념이 수사 연구기관에 각광을 받고 있다. 하지만 초동조치 대응인력 및 예비분석관들이 구체적으로 어떤 훈련을 받아야 하는지에 대한 연구는 그다지 주목받지 못했다. 오히려 많은 조직에서 초동조치 대응인력이 전문적인 디지털 포렌식 분석관과 같은 실력을 갖추어야 한다고 여기고 있다. 본 연구에서는 '이상적인' 상황에서 디지털 수사의 초동조치 대응인력과 예비분석관들이 어떤 능력을 갖추어야 하며, 하드웨어 및 소프트웨어 측면에서의 필요사항과, 어쩌면 가장 중요하다 할 수 있는 교육훈련 조건에 대해 논하고자 한다.

Background and Purpose : Emergencies in the school setting occurs frequently. Therefore, the role of first responders is important. General teachers in elementary schools are expected by first responders in school emergencies. This study attempted to assess needs and demands assessment on the first aid education of general teachers in elementary schools. Method : The subjects of this study were 71 general teachers from 8 elementary schools. Data were collected by the questionnaire during the period from March 19 to April 13, 2007. The data were analyzed through frequency, Cronbach's ${\alpha}$, Independent Two samples t-test, paired T-test, One Way ANOVA, Pearson's Correlation by SPSS win 12.0. Result : 1. It showed that 47.9%(34 persons) of general teachers answerd that they experienced emergencies in elementary school setting. Experienced emergencies were wounds(cut, laceration, abrasion etc.) 79.4%(27 persons), bleeding(including epistaxis) 64.7%(22 person), fracture(including dislocation, sprain) 44.1%(15 person), sting or bite 29.4%(10 persons). 2. It showed that 95.8%(68 persons) of subjects answerd that first aid education are necessary. Also 91.5%(65 persons) of subjects answerd that will be educated first aid if opportunities is given. 3. The total mean showed $2.39{\pm}.40$ in necessities of first aid education and $2.17{\pm}.36$ in needs of first aid education by 3 points Likert scale. Ranking 1 in necessities and needs of first aid education was bleeding control. 4. The total mean in necessities and needs of first aid education showed statistically significant differences(t = 3.453, p = .002). 5. The necessities of first aid education showed significant positive correlations with necessities and needs of first aid education(r = .521, p = .002). Conclusion : These results suggest that education program of first aid on elementary general teachers must be developed through necessities and needs assessment of first aid education and instructors must searched methods to increase needs of first aid.

Objective: The feasibility of a gonadotropin-releasing hormone agonist (GnRHa) trigger in normal responders is still a matter of debate. The aim of this study was to compare the number of mature oocytes, the number of good-quality embryos, and the live birth rate in normal responders triggered by GnRHa alone, GnRHa and human chorionic gonadotropin (hCG; a dual trigger), and hCG alone. Methods: A retrospective cohort study was conducted at the infertility clinic of a university hospital. Data from 200 normal responders who underwent controlled ovarian hyperstimulation and intracytoplasmic sperm injection with a GnRH antagonist protocol between January 2016 and January 2017 were reviewed. The first study group consisted of patients with cycles triggered by GnRHa alone. The second study group consisted of patients with cycles triggered by both GnRHa and low-dose hCG (a dual trigger). The control group consisted of patients with cycles triggered by hCG alone. Results: The groups were comparable in terms of demographics and cycle characteristics. The numbers of total oocytes retrieved and metaphase II oocytes were similar between the groups. The total numbers of top-quality embryos were 3.2±2.9 in the GnRHa group, 4.4±3.2 in the dual-trigger group, and 2.9±2.1 in the hCG group (p=0.014). The live birth rates were 21.4%, 30.5%, and 28.2% in those groups, respectively (p=0.126). Conclusion: In normal responders, a dual-trigger approach appears superior to an hCG trigger alone with regard to the number of top-quality embryos produced. However, no clinical benefit was apparent in terms of live birth rates.
