우리나라는 좁은 국토에 비하여 인구밀도가 높아 광복 이후 도시에는 아파트에 많은 인구가 살아 왔고, 최근 재개발 및 재건축으로 도시를 재정비함에 있어서도 아파트가 주된 건설 형식으로 진행 중이다. 그러나 도시화와 산업화로 이웃 간에 온정이 사라지고, 개인주의와 사생활 보호, 익명성 등으로 아파트 거주민들은 이미 범죄에 노출되어 있고, 이러한 현상이 사회적으로 큰 문제시 되었다. 미국과 영국에서는 1960년대 말부터 도시의 환경에 대한 연구를 시작하여 방어공간(Defensible Space)이론, 환경설계를 통한 범죄예방이론(CPTED)을 통하여 환경과 범죄간의 연구를 발전시켜 왔다. 우리나라에서도 최근 판교신도시 건설 및 부천시의 도시개발 계획 등에서 환경과 범죄의 관계를 반영하여 범죄가 발생하기 어려운 도시환경을 만들고자 민(民), 관(官), 학(學), 경찰(警察) 등 여러 분야에서 머리를 맞대고 연구하고 있다. 이번 연구에서는 기존의 연구와는 다른 시각으로 아파트의 형태별 범죄유형을 분석하였다. 아파트의 분류 방법 중 평면의 형식에 따른 분류로 계단실형 아파트와 편복도형 아파트를 기준으로 하고, 거주민들이 발생면(發生面)이나 빈도면(頻度面)에서 가장 많이 체감(體感)한다고 볼 수 있는 절도사건의 유형별로 비교 분석하였다. 창원시내에서 발생하여 경찰에 신고된 절도사건을 중심으로 주거침입절도, 오토바이 및 차량 등 절도, 노상에서 발생하는 날치기, 기타 등으로 분류를 하였고 창원시내 아파트 중 서로 인접하여 비슷한 지역에 위치하고 있는 비교대상 아파트 12개를 선정하여 계단실형 아파트와 편복도형 아파트를 분류하여 서로 비교, 분석하였다. 주거침입절도는 계단실형과 편복도형 아파트에서 비슷한 비율로 발생하였고, 오토바이 및 차량 등 절도는 편복 도형에서, 날치기는 계단실형 아파트에서 높은 비율로 나타났다. 특히, 다양한 여러 세대가 함께 거주하는 아파트에서는 다른 지역과 달리 오토바이 및 차량 등 절도가 많이 발생하고 있어 지상 및 지하 주차장에 대한 방범대책이 요구된다.

Strontium (Sr) commonly exists in rock, groundwater, soil, plants, and animals. The Sr isotope ratio offers important information as a tracer on nature because the Sr isotopic composition is not fractionated by any biological process in these ecosystems. Hence, Sr isotope ratio has been used in several studies on tracing the Sr source for contaminated sites and human migration. In this study, we developed a separation method for Sr content, and then improved Sr isotope analysis using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). A powdered rock standard (NIST 2710a) was used to determine the removal of interference elements (Rb and Ca) and the recovery rate of Sr content. The results ranged from 98% to 106%. Additionally, three standard samples (NBS 987, IAPSO and NIST 1486) were analyzed to evaluate the precision and accuracy of the results. The measured $^{87}Sr/^{86}Sr$ ratio for all the samples were consistent with the reported values, within an error. These results indicate that our established Sr separation and Sr isotope measurement methods are reliable and can hence be useful in the fields of environmental and forensic sciences.

Purpose: Education provided in many Korean medical colleges still isn't free from the contents of the "2+4 year program." Korean medical colleges especially holds onto the belief that humanities must be taught to the lower grades. Methods: I introduced the six-year integrated program and reversed the order of the existing education program. The new program assigned anatomy, physiology, and biochemistry to the 1st years, and humanities subjects such as forensic medicine and medical ethics to the 4th, 5th, and 6th years. Results: Increased participation and interests among students. Conclusion: Occupational and Environmental Medicine (OEM) at the level of pre-medicine brings harm rather than good.

Gastric cancer (GC) is the fifth most common cancer in the world, with a wide variation in incidence rates across different geographical areas. In Iran GC is the most common cancer in males and it is reported to be the third most prevalent after breast and colorectal in females. A geographical information system (GIS) allows investigation of the geographical distribution of diseases. The purpose of the present study was to explore the relationship between gastric cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. Of all cases, 672 (73.8%) were in males with a sex ratio of 3 to1. The highest incidence by cities was seen in Namin with 137.5 per 100,000. The results of this study showed that the distribution of GC around the Sabalan volcanic mountain was significantly higher than other places in the same province. These results can be considered as a window to future comprehensive research on gastric cancer.

This study was performed to summarize application of ${\delta}^{13}C$, ${\delta}^{37}Cl$ and ${\delta}D$ of trichloroethylene (TCE) to studies on environmental forensic field regarding identification of TCE sources and evaluation of contribution of TCE to groundwater using data collected from literatures. ${\delta}^{13}C$, ${\delta}^{37}Cl$ and ${\delta}D$ of TCE give some information regarding sources of TCE because they show specific value according to manufacturing method. Also, TCE do not show a significant isotopic fractionation owing to adsorption and dilution. The isotopic fractionation mainly occurs by biodegradation. In addition, isotopic fractionation factor for TCE is different according to a kind of microorganism participated in biodegradation. However, the isotopic data of TCE have to be applied with chemical compositions of TCE and other hydrogeologic factors because isotopic fractionation of TCE is influenced by various factors.

The submerged floating tunnel (SFT) is tethered by mooring lines anchored to the seabed, therefore, the structural integrity of the anchor should be sensitively managed. Despite their importance, reaction forces cannot be simply measured by attaching sensors or load cells because of the structural and environmental characteristics of the submerged structure. Therefore, we propose an effective method for estimating the reaction forces at the seabed anchor of a submerged floating tunnel using a structural pattern model. First, a structural pattern model is established to use the correlation between tunnel motion and anchor reactions via a deep learning algorithm. Once the pattern model is established, it is directly used to estimate the reaction forces by inputting the tunnel motion data, which can be directly measured inside the tunnel. Because the sequential characteristics of responses in the time domain should be considered, the long short-term memory (LSTM) algorithm is mainly used to recognize structural behavioral patterns. Using hydrodynamics-based simulations, big data on the structural behavior of the SFT under various waves were generated, and the prepared datasets were used to validate the proposed method. The simulation-based validation results clearly show that the proposed method can precisely estimate time-series reactions using only acceleration data. In addition to real-time structural health monitoring, the proposed method can be useful for forensics when an unexpected accident or failure is related to the seabed anchors of the SFT.

Floods are among the most common natural hazards in urban areas. To mitigate the problems caused by flooding, unstructured data such as images and videos collected from closed circuit televisions (CCTVs) or unmanned aerial vehicles (UAVs) have been examined for flood management (FM). Many computer vision (CV) techniques have been widely adopted to analyze imagery data. Although some papers have reviewed recent CV approaches that utilize UAV images or remote sensing data, less effort has been devoted to studies that have focused on CCTV data. In addition, few studies have distinguished between the main research objectives of CV techniques (e.g., flood depth and flooded area) for a comprehensive understanding of the current status and trends of CV applications for each FM research topic. Thus, this paper provides a comprehensive review of the literature that proposes CV techniques for aspects of FM using ground camera (e.g., CCTV) data. Research topics are classified into four categories: flood depth, flood detection, flooded area, and surface water velocity. These application areas are subdivided into three types: urban, river and stream, and experimental. The adopted CV techniques are summarized for each research topic and application area. The primary goal of this review is to provide guidance for researchers who plan to design a CV model for specific purposes such as flood-depth estimation. Researchers should be able to draw on this review to construct an appropriate CV model for any FM purpose.

사후경과시간(PMI)을 추정하기 위하여 사용되고 있는 유효적산온도(ADD)를 계산하는데 있어서 가장 중요한 요인 중 하나는 바로 사건 현장의 대기 온도를 최대한 정확하게 추정하는 것이다. 지금까지 사건 현장의 대기 온도를 추정하는 방법으로는 사건이 일어난 현장 근처의 기상청 온도를 그대로 적용하거나, 보정 온도를 고려하여 사용하거나, 주변 기상청 온도와 사건 현장 대기 온도의 선형 회귀분석을 통해 과거 일정기간 동안의 현장 대기 온도를 추정하였다. 이 때, 온도 추정 방법에 따라 온도 추정값이 달라질 수 있으며, 측정 조건이나 온도에 영향을 줄 수 있는 풍량, 풍속, 습도, 강우량 등 환경 요인에 따라서도 추정값의 정확도가 달라질 수 있다. 따라서 본 연구에서는 국내의 환경 요인 및 측정 조건들을 대상으로 보다 다양한 온도 추정 방법들에 적용하여 과거 일정기간 동안의 현장 대기온도를 추정하고, 이렇게 추정된 온도와 실제 온도와의 비교를 통하여 국내 온도 추정에 미치는 영향을 연구하고자 한다.

Megaselia scalaris, also known as the scuttle fly, has a humpbacked morphology and was categorized as an insect undergoing complete metamorphosis. Megaselia scalaris was reported to be found in diverse environments. Recently, the scuttle fly has been a focus of studies by forensic scientists, geneticists, and developmental biologists. However, detailed research into scuttle fly development is still unclear. Therefore, the current study has been performed to elucidate the development of Megaselia scalaris. The scuttle fly undergoes four distinct stages of development: egg, larva, pupa and adult fly. After mating, the scuttle fly eggs hatch within one day and become larvae. The newly generated larvae go through 1, 2, and 3 instar stages within a period of 5~10 days. The instar stage 1 takes 1~2 days, instar stage 2 takes 1~2 days, and instar stage 3 takes 3~5 days. Depending on the environmental temperature, the pupae stage takes approximately 10~15 days to complete. The pupa stage can be divided into five sub-stages: 1~3 days, 4~6 days, 7~9 days, 10~12 days and 13~15 days. After molting, the newly formed adult scuttle fly can fly after one day. The morphological characteristics of the scuttle fly during each stage of development was detailed within this study.
