Here, we report an autopsy case of an unusual hanging that was misinterpreted asa case of homicidal strangulation, as th body was found on the scene of a house fire. A 29-year-old unmarried woman hanged herself from the gas pipe using a bath towel. Subsequently, the pipe broke and a fire broke out after an explosion. However, as theinitial postmortem investigation revealed the absence of cherry-pink lividity and as aburnt bath towel was found around her neck, this case was misunderstood as a caseof arson after homicidal strangulation. The cause and manner of death in this casewere finally determined based on the autopsy findings of ligature marks that are typicallynoted in cases of hanging and the presence of a burnt electric lock and a brodengas pipe that were noted at the suicide scene.

안효정,장지현,장원섭 한국직업교육학회 2017 職業 敎育 硏究 Vol.36 No.5

This study aimed to verify effects of the meaning of work in career orientation and career development preparation behavior. To achieve the purpose, this study analyzed the relationships between the meaning of work and career orientation, between the meaning of work and career development preparation behavior. For this study, the survey was conducted on the cabin crews who were working in an domestic airline company, K-Airline and data gathered from 326 crews were used for analyses. As a method to investigate, this study used a multiple regression analysis. The analytic results of this study indicated that the meaning of work served as the variable that has positive effects on career orientation and career development preparation behavior. When perceiving it as recognition, it appeared to be directed toward general managerial orientation, technical・functional orientation. And it was found that Life style orientation assumed the importance when perceiving the meaning of work as society contribution. Especially, career development preparation behavior showed the high level when perceiving the meaning of work as growth opportunity. Basing on these finding, the practical implications of HRD and suggestions for the future research were also discussed. 이 연구는 항공사 객실승무원이 인식하는 일의 의미가 그들의 경력지향성과 경력개발 준비행동과 어떠한 관계를 나타내는지에 대하여 실증적으로 검토하였다. 이를 위해 이 연구는 국내 K항공사에서 근무하는 객실승무원 326명의 자료를 분석하였고, 연구모형의 검증을 위한 방법으로 단계적인 다중회귀분석을 실시하였다. 분석 결과, 일의 의미는 경력지향성과 경력개발 준비행동에 유의한 효과를 나타냈다. 먼저 일을 사회적으로 인정받기 위한 것으로 의미화하는 수준이 높은 경우 관리자나 전문가 지향의 경력지향성이 높았고, 사회기여로 인식하는 수준이 높을수록 라이프스타일 지향의 경력지향성이 높았다. 그리고 일을 자신의 성장기회로 의미화하는 수준이 높을 때 경력계획수립과 경력탐색행동 등 경력개발 준비행동의 수준이 높게 나타났다. 이러한 연구의 결과를 토대로 인적자원개발 분야에서의 실무적 시사점 그리고 향후 연구에 대해 제안하였다.

Purpose: Human epidermal growth factor receptor 2 (HER2)- positive luminal B type comprises estrogen receptor (ER)-positive and HER2-positive cancers, and HER2-negative luminal B type comprises ER-positive cancers showing a Ki-67 labeling index ≥14% or progesterone receptor (PR) expression of <20% according to the St. Gallen consensus 2013. The current study aimed to classify intrinsic subtypes according to the St. Gallen consensus 2013 and determine the differences in clinicopathological parameters and survival outcomes among the molecular types, especially among the luminal types. Methods: Assessment of molecular types was performed for 267 invasive ductal carcinomas. The differences in clinicopathological parameters, disease- free survival (DFS), and overall survival (OS) among the molecular types were analyzed. Results: The luminal B type was the most prevalent, at 44.9%, followed by the luminal A, triplenegative (including basal-like type), and HER2 type, at 21.7%, 18.7%, and 14.6%, respectively. There were statistically significant differences in size (p=0.003), nodal status (p=0.046), histologic grade (p<0.001), p53 (p<0.001) and cyclooxygenase 2 (COX-2) positivity (p=0.002), recurrence (p=0.001) and death rates (p=0.036), DFS (p=0.002), and OS (p=0.039) among the molecular types. Significant differences in size (p=0.009), nodal metastasis (p=0.019), histologic grade (p<0.001), p53 positivity (p=0.001), and PR expression (p<0.001) were noted between the luminal A and B types. Among the luminal B type cancers, the distributions of ER and PR scores showed significant differences (p=0.003, p=0.003). p53 positivity in the luminal B type cancers was related to shortened DFS (p=0.034). In luminal type cancers, COX-2 positivity was related to longer DFS (p=0.026). Conclusion: Different management guidelines should be considered for the luminal A and luminal B breast cancer types. Positive p53 expression in luminal B type cancers and negative COX- 2 expression in luminal type cancers seem to be related to poor clinical outcome.

Ecumenically, RPAS(Remotely Piloted Aircraft System) operation has been increased and the related accidents also have occurred. Accordingly, national authorities, organizations and industry have been striving for amendment and enactment of policy and regulation related to the RPAS(Remotely Piloted Aircraft System) operation. And ICAO had performed the joint study to make international standards through UASSG(Unmanned Aerial System Study Group). Recently this group has been switched to the panel meeting, RPASP(Remotely Piloted Aircraft System Panel). It has been discussed to make the related annex, SARPs(Standards and Recommended Practices) and etc. in RPASP. In this paper, we investigated the trend of study and development for ICAO RPAS policy and regulation. Based on these results, we suggested considerations to prepare domestic policy and regulations. 세계적으로 무인기 활용이 증가하고 이와 관련한 사고 보도도 잇따르고 있는 가운데 각국 정부 당국, 관련 기관 및 산업체 등에서는 무인기 운영 관련 정책 및 규정 제 개정을 위한 노력에 박차를 가하고 있다. 또한 이와 동시에 국제민간항공기구에서 관련 연구조직(UASSG, Unmanned Aerial System Study Group)을 통해 국제 표준 마련을 위한 공동 연구를 진행해 왔다. 최근에는 국제민간항공기구에서 무인기패널체(RPASP, Remotely Piloted Aircraft System Panel)를 조직하여 무인기의 민간공역 통합 운영을 목표로 관련 부속서, 표준 및 권고 등을 제 개정하기 위한 논의를 수행하고 있다. 본 논문에서는 국제민간항공기구의 무인기 정책 연구 및 개발 동향을 조사하고, 이를 통해 국내 무인기 정책 마련을 위해 필요한 사항을 제안하였다. 이는 국제적인 무인기 정책 및 규정 개발 동향을 파악하여 관련 산업개발 방향 설정 및 국내 규정 마련에 기초자료로 활용할 수 있을 것이다.

각국의 무인기 카테고리 분류 기준에는 차이가 있으나, 대부분의 국가에서는 중량을 기준으로 25 kg(55 lb) 이하를 소형무인기로 분류하고 있다. 소형무인기는 주로 군사용, 공공용으로 개발되어 왔으나, 최근에는 취미 및 미디어 촬영 등을 위하여 민간분야로 확산되고 있다. 하지만 이러한 무인기를 운영하기 위해서는 유인기와 같은 수준의 안전성을 확보할 필요가 있다. 이는 무인기가 유인기와의 충돌이나 추락에 의해 지상 피해를 유발할 수 있기 때문이다. 본 논문에서는 미국과 유럽의 국가들을 중심으로 소형무인기 운용을 위한 입법 및 운용 승인제도에 대해 조사하였다. 또한 소형무인기 운영을 위한 국내 제도 마련 방안에 대해서도 연구하였다. Although there are differences in the classification of category adopted by each country, small UAS is usually classified as the one less than 25 kg. UAS has been mainly used for military and public purposes, but in recent years, it has spread to the private sector for hobby, media, and so on. Especially, considering the nature of the operating region and applications, it is necessary to improve operating time, noise and vibration in small UAS to ensure the same level of safety with a manned aircraft. This is because the drone can pose health and safety hazard through collision with manned aircraft or crashing into the ground. In this paper, we investigated operational regulations in the United States and European countries. Based on the investigation, a domestic system development plan for small UAS operation is under development.

Sebaceous Carcinoma Arising in Mature Cystic Teratoma of Ovary

안효정,정수진,정용한,윤혜경 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.4

Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous- type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, measuring 22.0 cm in diameter, filled with sebaceous material and a few hairs. A luminally-protruding solid mass measuring 4.0 cm in diameter was also noted. Microscopic findings revealed lobular or diffusely arranged basophilic, atypical sebaceous cells connected to a typical mature cystic teratoma. Tumor cells demonstrated positive immunoreactivity for high molecular weight cytokeratin, cytokeratin 7, cytokeratin 19, epithelial membrane antigen, and carcinoembryonic antigen. Here, we present a case of sebaceous carcinoma arising from a mature cystic teratoma along with a review of previously published reports.

The purpose of this study was to find out the effectiveness of the nature game in environmental education at an elementary school and make suggestions for further improvement. While the nature game was applied to the experimental group, the control group was taught with the traditional teaching methods focused on a teacher's lecture. To analyze the effectiveness of nature game on environmental education, the pre- and post-test for children's knowledge, function and attitude about environment were applied to both groups. Their scores were not significantly different(p>0.05) to both groups in terms of the pre-test. However, the post-test scores of the experiment group showed higher than the control group (p<0.05). This result indicates that teaching environmental education through the nature game is more effective than a traditional teaching method with teacher's lecture. Consequently, we are urgently requested to develop systematical teaching materials in environmental education. The goal of environmental education can be achieved by providing the significance of teaching materials should be recognized.
