Development of Integrated Device of Trace Bloodstains Imaging and Age Analysis / 法医学杂志

Objective To develop a device of trace bloodstains imaging and age analysis, so as to provide a non-destructive, simple and objective method for age estimation of bloodstains at the crime scene. Methods Based on the principle of digital imaging and color pattern analysis, the mobile terminal of the device was used to collect images of bloodstains of different ages. The time-dependent pattern of 6 parameters （R, G, B, C, Y, M） reflecting the changes of color of images of different ages was obtained by computer image analysis. A multiparameter comprehensive inference equation of bloodstains age was established and embedded into the device software to realize the intelligent inference of the bloodstains age. Then the capability and reliability of the device was verified. Results This integrated device of bloodstains imaging and age analysis could quickly collect bloodstains at the crime scene and automatically analyze and infer the age of bloodstains combined with related intelligence software. In the blind test, the detection accuracy of this device was 95% in both natural light airtight group and dark airtight group, and 80% in the natural light ventilation group. Conclusion The integrated device of trace bloodstains imaging and age analysis can be used in a simple manner, which provides a new objective method for bloodstains age estimation.

Spiritual Approach to Healthy Aging

Everyone has his/her own life story on the personal experience. C. Y. Gerkin called the story 'The Living Human Document.' Pastoral counseling is to listen to and to analyze the story, to integrate past experiences with newly-analyzed experiences, and to give the story a new meaning and to make the subject construct a hopeful world. Ultimately, pastoral counseling is to make the subject to live 'a spiritual life,' a life in which the activities of God for human beings are recognized. In general, people are anxious and afraid of 'sin' and 'death,' and the latter becomes serious when they are in their old age, the time when people have to think of their own death instead of others' death. Therefore, it is important in one's old age how one makes use of the remaining time, and whether the last chance could be applied may decide whether one can live 'a spiritual life.' The mention of death for the elderly is not 'the close of life' but 'the completion of life,' and should be considered a course in order to complete 'the remaining time' or 'the remaining life.'
