If the evidence required to attest to the injuries of victims of accidents and violent crimes is properly managed by emergency department medical staff, it is more likely that judicial institutions will accept the evidence as legally effective.
In this study, we developed a simulation training program so that nurses, who are usually the first medical professionals that patients encounter in an emergency department, can perform forensic nursing interventions, such as recognition of forensic patients and collection of evidence. Following this, we evaluated the effectiveness of this program. The program was developed in three parts by applying the ADDIE design model based on forensic nursing competency. Section 1 was designed to conduct traffic accident simulation without prior knowledge of forensic nursing; Section 2 comprised theoretical lectures and traffic accident simulation through real-time feedback from instructors for acquiring forensic nursing competency; Section 3 evaluated the efficacy of the simulation program by applying it in the domain of child abuse, where forensic nursing is required.
To verify its effectiveness, a control group pretest-posttest design was used. A total of 47 emergency department nurses, each with more than six months of work experience, participated in this research. The experimental and control groups comprised 23 and 24 nurses, respectively. The homogeneity of the experimental group and the control group was confirmed through a preliminary survey on forensic nursing competency, and the training program was implemented for the experimental group. The results showed a statistically significant increase in forensic nursing competency (t=-11.40, p=.000) and performance (Z=-2.521, p=.012) of the experimental group compared to pre-training. Additionally, the results of evaluating the developed training program revealed that the lecture on theory scored 4.79ยฑ0.27, simulation education had a score of 4.78ยฑ0.29, simulation design scored 4.42ยฑ0.45, and satisfaction with the training program had a score of 4.82ยฑ0.28, with 5 being the maximum possible score.
The results demonstrated that the forensic nursing competency -based simulation training program developed in this study improved forensic nursing competency and the performance of emergency department nurses. This program can also contribute to defending the legal rights of emergency department patients.๊ตญ๋ฌธ์ด๋ก โ

ํ ๋ฒ : 2008-221331. Objectives
Composite resins (CRs) and flowable resins (FRs) have been widely used in dentistry, with increasing requirements of tooth-colored restorations. It is hard to recognize color differences between CRs/FRs and teeth after the esthetic restoration, though the color of CRs/FRs do not perfectly match the color of teeth. The visual perception of reduced color differences is called 'blending effect (BE)' and plays an important role to success the esthetic restoration under a limited number of colors of restorative material. According to previous studies, BE increased when two types of color were attached. Furthermore, BE increased under various conditions such as the smaller size of restoration, the less color differences, and the more transparency.
There have been few researches on color adjustment capacity of layered CRs. However, clinical importance of the color adjustment capacity for non-layered CRs has grown while therere no surrounding tooth structures such as class III, IV cavities and diastema closures.
In the previous study of layered CRs, BE increased with the higher transparency. However, non-esthetics results are drown from excessive transparency in non-layered CR restorations cases. Therefore, BE is important in this clinical conditions. In this study, BE is measured with various adjacent material of CRs/FRs under above-mentioned clinical conditions using CIEL*a*b* color system. The CIEa* parameter is selected as measurement parameter.
2. Methods
5 manufacturers were selected with 3 shades(A2, A3, A3.5) CRs and FRs. 10mm X 5mm X 2mm resin composite blocks, attaching tightly red and white tiles on each side, were produced customized. The color of the samples was measured using Spectroradiometer. The measurement was started from red tile side toward white tile with 40 times intervals moving as 0.25mm. 3 samples were conducted on each experimental group.
XYZ coordinates from the Spectroradiometer were transformed into CIE(1976)L*a*b* color system. Among CIE(1976)L*a*b* parameters, CIEa* values were analyzed for BE measurement. CIEa* values showed exponential decay such as f(x)=a ร expโก(-bรx)+c. The CIEa* values converged to 'c' with moving to red tile, which means that the influence of red tile was extinct. In this case, BE is defined as the value of (mm) at the point of CIEa*, c+1.
For statistical analysis, two-way ANOVA with Tukey HSD and Duncan were performed using PASW.
3. Results
The value of BE(mm) of CRs was greater than that of FR's. Among the 5 CRs, Estelite Sigma Quick showed the largest value with 3.321mm, which means the BE of red tile substantially reaches up to 3.321mm. Gradia > Charisma > Premisa > Metafil CX were followed. Among the 5 FRs, Charisma Flow showed the largest value with 2.692mm. Estelite Quick Flow > Premisa Flow > Metafil Flo > Unifil Flow were followed.
After statistical analysis with ANOVA, statistically meaningful differences between CRs and FRs(p0.05) were observed. Furthermore, 3 homogeneous sub-groups, which are (Premisa/Premisa Flow), (Charisma/Charisma Flow, Estelite/Estelite Flow), (Metafil/Metafil CX, Gradia/Unifil Flow), were classified after execution of Tukey HSD and Duncan.
