일반적으로 가정 내에서 발생하는 안전 사고의 비율은 비장애인에 비해 청각장애인이 높다. 이는 외부인에게 도움을 받을 수 없는 상황에서 청각장애인 스스로 위험상황에 대한 소리를 인지하지 못하기 때문이다[1]. 본 연구에서는 이러한 문제를 해결하기 위해 시각적 효과 또는 진동 신호를 통해 청각장애인들에게 사고 상황 인지를 돕는 시스템을 제안한다. 현재 상용 제품의 경우는 청각장애인이 스마트기기를 소지하고 있을 때만 알림을 인지할 수 있기 때문에 긴급 상황에서 효과가 떨어질 수 있다. 따라서 제안 시스템에서는 어플리케이션 알림과 함께 건물내 전등 색상에 변화를 주는 서비스를 개발하여 스마트 기기를 소지하지 않는 상황에서도 위험상황에 대한 즉각적인 인지를 통해 위험에 대처할 수 있도록 한다. 소리를 시각화하는 것이 본 연구의 핵심 방법론이며 이를 위해 Convolutional Neural Network 모델과 라즈베리파이를 활용하였다.

부패 시신의 신원확인을 위한 DNA 분석 조직의 비교 및 검증: 발톱 부위별 조직과 늑연골 조직 비교를 중심으로

정종근(Jung Jong Keun),임상범(Lim Sang Beom),조우철(Cho Woo-Cheol),손현지(Son Hyun Ji),이민호(Lee Min Ho),이진명(Lee Jin Myung),신상철(Shin Sang Cheul) 경찰대학 경찰학연구편집위원회 2021 경찰학연구 Vol.21 No.3

변사사건에서 변사자의 신원확인은 수사에 중요한 요소이나 부패로 외형적 확인이 불가능한 경우 다양한 방법을 통해 신원확인이 이루어진다. 하지만 다른 조직에 비해 부패가 느리게 진행되는 대퇴골, 골편, 치아와 같은 조직들은 전처리 과정을 거쳐야 하므로 신원확인이 다소 지연된다. 본 연구에서는 2021년 1월에서 6월까지 부검의뢰 된 부패된 시신 12구의 발톱 부위별 조직과 늑연골 조직의 DNA 농도, 분해지수, DNA형 검출 빈도를 비교하였다. DNA 정제에 사용한 조직 무게는 0.05g ~ 0.33g이며, DNA를 추출 후 정량하였을 때 12구 중 11구의 발톱 부위별의 모든 조직에서 DNA가 추출되었다. DNA 분해지수를 비교 시 발톱 부위별 조직과 늑연골 조직의 평균값이 2 이하로 검출되었으며 DNA형 분석에서도 발톱의 조체 조직 11개와 늑연골 조직이 동일한 값으로 검출되었다. 부패된 시신의 부검 후 신원확인에 의뢰되는 조직 중 전처리가 필요한 뼈 조직은 신원확인용 감정물 중 상당 부분을 차지하고 DNA 분석의 전처리 과정에 많은 시간이 소요되는데, 이를 전처리 과정이 필요 없는 발톱의 조체 조직으로 대체 가능성을 확인하였다. 또한 늑연골 조직에 비해 간단히 채취할 수 있는 발톱 조직을 사용한다면 변사 사건 중 부검하지 않는 부패된 시신의 신원확인을 위해 유용하게 사용할 수 있을 것이다. Identification of unknown dead bodies is an essential element for investigation of death cases. In particular, there are a lot of cases with corpses visually(physically) unidentifiable due to decomposition, thus several different kinds of methods are being used for identification of decomposed dead bodies. However, tissues such as femurs, bone fragments, and teeth, which decay more slowly than other tissues, have to undergo a pre-treatment process, which delays the identification. In this study, the DNA concentration, degradation index, and detection frequency of DNA profiles were compared in the toenail tissues (nail-root, nail-bed, and nail-free-edge) and the costal cartilage tissues of 12 decomposed corpses requested for autopsy from January to June 2021. The weight of the tissue used for DNA purification was 0.05 g ~ 0.33 g. After DNA extraction and quantification, DNA was successfully extracted from all the tissues except for one toenail tissue. Most of the DNA degradation index values of toenail tissues and costal cartilage tissues were measured to be 2 or less, and the DNA profiles showed the concordant results between the 11 nail-bed tissues and the 11 costal cartilage tissues. After autopsy of decomposed bodies, a large portion of the tissues requested for identification requires pre-treatment process, which leads to take a lot of time for DNA analysis. Here we have confirmed the possibility of replacing those tissues with nail-bed tissues that does not require a pre-treatment process. Furthermore, if toenail tissues, which can be easily collected compared to costal cartilages, are used, it will be useful for identification of decomposed bodies from death cases that are not autopsied.

PURPOSE: The purpose of this study was to compare and analyze the effects of Taekwondo training including 8-week inspiratory muscle training on physical fitness, CRP, pulmonary function and isokinetic muscle function of middle-aged male smokers. METHODS: 21 middle-aged male smokers were divided into 3 groups: inspiratory muscle training+Taekwondo training group (n=7), Taekwondo training group (n=7) and control group (n=7). Measurement variables were physical fitness (Body composition, muscular strength, muscular endurance, flexibility, cardiorespiratory function, balance), CRP, pulmonary function (FVC, FEV1, FEV1/FVC), and isokinetic muscle function (peak torque %BW, average power %BW). The repeated measure ANOVA was conducted to analyze the differences and interactions between groups and periods. In the case of any difference, t-test was conducted to perform post hoc test between pre and post treatment and the contrast was conducted to perform post hoc test between groups. One-way analysis of variance (ANOVA) was used between groups, and repeated measures t-test was used between groups. All significance levels were verified at .05. RESULTS: As a result, the combined exercise group also showed statistically significant changes in the physical fitness (Body composition, muscular strength, muscular endurance, flexibility, cardiorespiratory function), pulmonary function (FEV1, FEV1/FVC), and isokinetic muscle function (peak torque %BW). CONCLUSIONS: Consequently, it shows that 8 weeks Taekwondo training including inspiratory muscle training made a positive effect on fat content, muscular strength, muscular endurance, cardio respiratory fitness, R-extension in peak torque %BW in middle-aged male smokers.
