In the forensic sciences, they form the basis for craniofacial reconstruction and identification methods. Since there are few FSTT data in the Slovak population, this study aims to enrich the data in well-defined age categories, taking into account differences between sexes and body mass index (BMI). The sample consisted of 127 participants aged 17 to 86 years from Slovakia. In addition to biological sex and age information, stature and body weight were recorded to calculate BMI. Subsequently, 17 facial anthropometric landmarks were used to measure FSTT using a noninvasive General Electric LOGIQe R7 ultrasound device. The mean values of FSTT were greater in the mouth region in males and in the zygomatic and eye regions in females. Differences between males and females, regardless of sex and BMI, were significant only at two landmarks. When BMI and age were taken into account, there were differences in 12 of 17 landmarks. Linear regression results showed the strongest correlation of most landmarks with BMI, followed by age and sex. When the FSTT was estimated in association with sex/age/BMI, landmarks in the zygomatic, mandibular, and frontal regions were the best regressors. The results of the present study demonstrate that B-mode ultrasound measurements of FSTT can be used in facial reconstruction as a function of BMI, age, and sex of the subject. Furthermore, the present regression equations can help practitioners in the forensic/medical field to calculate individual tissue thickness.</p>","PeriodicalId":18484,"journal":{"name":"Medicine, Science and the Law","volume":" ","pages":"23-31"},"PeriodicalIF":1.5,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9717856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study was to use deep learning in determining sex from clavicles within the Thai population and obtain the accuracies for the validation set using a convolutional neural network (GoogLeNet). A total of 200 pairs of clavicles were obtained from 200 Thai persons (100 males and 100 females) as part of a training group. For the deep learning approach, the clavicle was photographed, and each clavicle image was submitted to the training model for sex determination. Training groups of 200 samples were made. Images of the same size were input into the training model. The percentage of the validation set accuracy was calculated from the MATLAB program. GoogLeNet was the best training model and get the result of validation set accuracy. The results of this study found accuracies for a validation set with the highest overall right lateral view of the clavicle with an accuracy of 95%.

The latest/fourth version of the General Principles of Suicide Prevention (ver. 4) was approved by the Cabinet in October 2022. Suicide by women and young people has increased in recent years, and the fourth version of the General Principles proposes enhanced measures to prevent suicide among those populations. We have also cited the need to promote efforts measures to prevent suicide among people who live alone. All four versions of the General Principles of Suicide Prevention include a suggestion describing the need for \"research to elucidate the circumstances of suicide. Since version 3, the category “promoting research to help promote general principles of suicide prevention” has included “in conjunction with a system to determine the cause of death.” The first Plan to Promote Determination of the Cause of Death was approved by the Cabinet in June 2014, and the latest version of this Plan was approved in June 2021. In order to promote the determination of causes of death, accurate cause-of-death statistics must be obtained. Several years have passed since the suggestionwasmade to ascertain the circumstances of suicide in conjunction with a system to determine causes of death; however, sufficient preparations are yet to be made, and apparently more time is necessary until such a system is definitively implemented. In order to implement preventive measures in accordance with the circumstances of suicide, studies of suicide prevention measures that are based on motives for suicide are necessary, as such motives would be closely associated with the determination of the circumstances of suicide. Two sets of suicide statistics are published in Japan: statistics reported by the National Police Agency (NPA), and the Vital Statistics reported by the Ministry of Health, Labour and Welfare. Only the statistics reported by the NPA list the motive for suicide. Prior to 2006, the NPA statistics provided a presumed motive for each suicide based on a suicide note or other corroborating documents, and since 2007 the NPA has provided up to three motives for suicide. The current statistics better reflect the reasons for suicide compared to the previous statistics, but the main motive for many suicides cannot be ascertained. It would thus be helpful to refer to both the currently reported statistics on suicide motives and previous statistics indicating the main motive in order to devise effective measures for the prevention of suicide. Urgently needed measures to prevent suicide could be devised by compiling a statistical report on the motives for suicide as reported by the NPA, and this compilation could be done promptly.
