Starvation, diabetes, alcoholism and hypothermia cause ketoacidosis in the human body; therefore, the cause of death can be determined by analyzing ketone bodies in the blood of the deceased. In the case of decomposition of the cadaver, however, since collecting intact blood is impossible, ketone body analysis is performed using the spleen. However, the index for diagnosing ketoacidosis is based on blood concentration, and its correlation with ketone bodies present in the spleen remains unknown. In particular, since decomposition proceeds rapidly during summer, when temperature and humidity are high, understanding the correlation between ketone bodies in the blood and spleen is important to estimate the state at the time of death from a decaying body. Therefore, in the present study, the correlation between ketone bodies in the blood and spleen of the deceased was explored. Ketone bodies (beta-hydroxybutyric acid [BHB] and acetone) in the blood and spleen were analyzed and compared from autopsies (>100 mg·L^-1 BHB, blood basis) conducted at the Daejeon Forensic Research Institute from June to December 2021. Moreover, the concentration of ketone bodies in the spleen juice and tissues was compared assuming the scenario of extreme decomposition. Ketone retention concentration in the blood and spleen was positively correlated, and the ratio of BHB concentration in the spleen to BHB concentration in the blood ranged from 0.52 to 1.08 (mean = 0.85 ± 0.12), although the ratio may vary depending on the degree of decomposition of the corpse.

Purpose: In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al. Materials and Methods: In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points. Results: Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders. Conclusion: The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

Progressive muscular dystrophy (PMD) is a primary muscle disease characterized by progressive muscle weakness and wasting, which is inherited by an X-linked recessive pattern and occurs mainly in males. There are several types of muscular dystrophies classified according to the distribution of predominant muscle weakness including Duchenne and Becker, Emery-Dreifuss, facioscapulohumeral, oculopharyngeal, and limb-girdle type. Clinical manifestations of PMD are clumsy, unsteady gait, pneumonia, heart failure, pulmonary edema, hydropericardium, hydrothorax, aspiration, syncopal attacks, and sudden cardiac death. The deceased was a 34-year-old man, and the onset of the first clinical symptom, gait disturbance, was in his late teens. His elder brother had the same disease and experienced brain death after a head trauma and died after mechanical ventilation was discontinued. After an autopsy, we found contracture of the joints, pseudohypertrophy of the calf, wasting and fat replacement of the thigh muscle, pericardial effusion (80 mL), fibrosis and fat replacement of the cardiac ventricular wall, pulmonary edema, and froth in the bronchus. The cause of death was heart failure and dyspnea due to muscular dystrophy. There was no sign or suspicion of foul play in his death.

Purpose: The objective of this study was to determine the minimum number of teeth in the anterior dental arch that would yield accurate results for individual identification in forensic contexts. Materials and Methods: The study involved the analysis of 28 sets of 3-dimensional (3D) point cloud data, focused on the labial surface of the anterior teeth. These datasets were superimposed within each group in both genuine and imposter pairs. Group A incorporated data from the right to the left central incisor, group B from the right to the left lateral incisor, and group C from the right to the left canine. A comprehensive analysis was conducted, including the evaluation of root mean square error (RMSE) values and the distances resulting from the superimposition of dental arch segments. All analyses were conducted using CloudCompare version 2.12.4 (Telecom ParisTech and R&D, Kyiv, Ukraine). Results: The distances between genuine pairs in groups A, B, and C displayed an average range of 0.153 to 0.184mm. In contrast, distances for imposter pairs ranged from 0.338 to 0.522 mm. RMSE values for genuine pairs showed an average range of 0.166 to 0.177, whereas those for imposter pairs ranged from 0.424 to 0.638. A statistically significant difference was observed between the distances of genuine and imposter pairs(P<0.05). Conclusion: The exceptional performance observed for the labial surfaces of anterior teeth underscores their potential as a dependable criterion for accurate 3D dental identification. This was achieved by assessing a minimum of 4 teeth.

본 연구는 대학생의 자기 주장성과 폭음 수준이 성폭력 피해를 예측하는지 알아보았고, 폭음 수준이 자기 주장성과 성폭력 피해 여부 간에 조절 역할을 하는지 탐색해 보았다. 대학생 405명이 연구에 참여하였고 익명성 보장을 위해 모바일 기반 설문 응답을 사용하였다. 설문지에 응답하지 않은 12명의 참여자를 제외한 393명(남: 161명, 여: 232명)의 자료를 분석하였다. 로지스틱 회귀분석을 통하여 자기 주장성, 폭음 수준, 자기 주장성과 폭음의 상호작용을 예측 변인으로, 성폭력 피해여부를 기준 변인으로 설정하여 분석하였다. 분석 결과 자기 주장성과 폭음 수준이 성폭력 피해 확률을 유의하게 예측하는 것으로 나타났다. 즉, 자기 주장성 수준이 낮을수록, 폭음 수준이 높을수록 성폭력 피해 확률이 유의함을 나타냈다. 또한 자기 주장성과 폭음의 상호작용이 성폭력 피해 확률을 유의하게 예측하였다. 상호작용에 대한 단순 주 효과 분석을 실시한 결과 폭음 수준이 낮은 집단의 경우 자기 주장성이 성폭력 피해 확률을 유의하게 예측한 반면, 폭음 수준이 높은 집단의 경우 자기 주장성이 성폭력 피해 확률을 유의하게 예측하지 않는 것으로 나타났다. 이러한 결과를 통하여 대학생의 성폭력 피해 예방을 위한 프로그램 적용 시 자기 주장성 훈련만이 아니라 건전한 음주 교육이 병행되어야 할 것을 제안하였다.

As the age of the sex crime perpetrators and victims is going down, the importance of Sex Assault Prevention Education (SAPE) is on the rise. In order to see how many students are aware of the SAPE which are currently being conducted in the local schools. A total of 600 students from five different primary schools in Kyongsan City area were questioned with the questionnaire. On the whole, the level of acknowledgement on the sexual assault is estimated as 20.52 out of total point 53.00. The point in each question is shown as low as follows; The notion of Sexual Assault (9.88 out of 19), recognition of Sexual Assault (5.45 out 11), way to cope with the sexual assault (6.60 out of 11), and knowledge on the symptom induced by the sexual assault (4.04 out of 12). The SAPE should be taught to the student from the young age frequently. The efficiency of SAPE will be increased by the health-care teachers who have the professional knowledge with the case studies and teaching materials like CD-ROMs. The health-care teachers as the SAPE lecturers require continuous training.

In this paper, the finite element analysis using ADINA has performed to investigate an accident that a man's head was damaged by the falling object. The simulation condition has defined by the point of forensic medicine view and the CCTV image analysis. From the CCTV image analysis, we expected that the sphere diameter of object is 15cm and object color is white. Assuming the falling mass is the ice mass, the results of the ADINA simulation show that a man's head can be broken by the falling ice mass.

Background: Published data regarding associations between the P275A polymorphism in the macrophage scavenger receptor 1 (MSR1) gene and prostate cancer (PCa) risk are inconclusive. The aim of this study was to comprehensively evaluate the genetic risk of P275A polymorphism in MSR1 gene for PCa. Materials and Methods: A systematic literature search was carried out in Pubmed, Medline (Ovid), Embase, CBM, CNKI, Weipu, and Wanfang databases, covering all available publications (last search was performed on Apr 27, 2015). Statistical analysis was performed using Revman 5.2 and STATA 10.1 software. Results: A total of 5,017 cases and 4,869 controls in 12 case-control studies were included in this meta-analysis. When all groups were pooled, there was no evidence that the P275A polymorphism had a significant association with PCa under dominant (OR=0.93, 95%CI=0.81-1.06, and p=0.28), co-dominant (homogeneous OR=0.97, 95%CI=0.56-1.68, and p=0.92; heterogeneous OR=0.93, 95%CI=0.74-1.15, and p=0.49), recessive (OR=1.10, 95%CI=0.65-1.87, and p=0.73), over-dominant (OR=0.93, 95%CI=0.75-1.15, and p=0.50), and allelic (OR=0.95, 95%CI=0.77-1.16, and p=0.61) genetic models. For stratified analyses by ethnicity and study design, no significant associations were found in the white race, the yellow race, the black race and mixed ethnicity, and the population-based case-control (PCC) and hospital-based case-control (HCC) studies under all genetic models. Conclusions: Based on our meta-analysis, the P275A polymorphism in the MSR1 gene is unlikely to be a risk factor for PCa.
