Foreign body aspiration is a cause of the accidental death at home. Therefore, early intervention and proper management is important. A bronchoscopy is indicated whenever there is a suggestive history and medical opinion. Occasionally, foreign body removal with bronchoscopy may be fail. But, on the situation, there is no definite recommended standard management. We experienced two cases of bronchial foreign body could not be removed with bronchoscopy at first intervention. The one was diagnosed too late. Endobronchial granulation tissue and edema made it impossible to find the foreign body at first bronchoscopy. After steroid and antibiotic therapy, foreign body could be removed with secondary bronchoscopy. Another was bronchial foreign body jammed tightly bronchus intermedius. Even after medical therapy, patient got aggravated. So foreign body was removed with bronchotomy.

협력치안을 통한 4대 사회악 근절방안에 관한 연구- 익산시와 익산경찰서의 사례를 중심으로 -
김연수,Kim. Yeon Soo 한국범죄심리학회 2015 한국범죄심리연구 Vol.11 No.1
이 연구는 현 정부의 가장 큰 관심사인 4대 사회악 근절방안으로 협력치안을 통한 접근을 제안하며, 협력치안의 모델을 가장 잘 보여주고 있는 익산시와 익산경찰서의 사례를 중심으로 4대 사회악 근절방안을 검토하였다. 전국적으로 4대 사회악을 근절하기 위한 다양한 노력이 시도되고 있지만, 근본적인 문제해결을 위해서는 지역사회경찰활동, 치안서비스 공동생산이론, 제3자 경찰활동 등에서 제안하는 바와 같은 지역사회 내 자원의 적극적인 협력과 지원을 토대로 하는 협력치안의 형태가 바람직하다. 특히, 4대 사회악이 비록 중앙정부의 의제설정에 따른 것이라는 특수성이 있으나, 성폭력, 가정폭력, 학교폭력, 불량식품이라고 하는 사회문제가 경찰이나 정부기관의 노력으로만 해소될 수 있는 문제가 아니라는 점에서 시민의 적극적인 관심과 지원이 필수적이다. 이 연구는 4대 사회악 근절을 위해 익산시가 ‘4대 사회악 근절 추진본부’를 설립하였고, 익산경찰서가 ‘맞춤형 통합지원 네트워크’를 구축하였지만, 일정부분 한계가 있다고 본다. 연구를 통해 확인된 한계를 극복하기 위해 다음과 같이 개선방안을 제안하였다. ① 지역자원 활용 강화, ② 지역자원의 추가발굴, ③ 4대 사회악 유형세분화와 대응정책 개발, ④ 정보공유를 통한 범죄예방전략 수립 등을 제안한다. This study proposes an approach to cooperative policing in the best interest of the countermeasures of the current government to eradicate four social evils. It was investigated a model of cooperative policing in the case of Iksan city and Iksan police department. Various efforts have been attempts to eradicate four social evils. However, in order to solve the fundamental problems in the form of cooperative policing, such as that proposed a community policing, police service co-production theory, and third party policing, that is based on the active cooperation of the resource in the community is desirable. Active interest in social issues(sexual violence, domestic violence, school violence, and food violations) is essential for the support of the citizens in that is not a problem that can be solved only by the police or government agency efforts. This study looks that build of ‘Promotion Headquarters for the Eradication of 4 Social Evils in Iksan city’ and ‘Integration Support Network of Iksan Police Department’ is a certain part of the limits for the eradication of 4 social evils. To overcome the limitations identified through the study suggest improvements as follows: ① strengthen local resource utilization, ② additional excavation of local resources, ③ 4 evils’ type specification and response policy development, ④ crime prevention strategies through information sharing.

SV40 Replication core origin에 존재하는 early palindrome의 구조와 기능에 대해 알아보기 위해 SV40 origin을 포함하는 0.8kb DNA fragment를 filamentous phage M13 DNA에 cloning시킨 후 oligonucleotide-directed site-specific mutagenesis에 의해 early palindrome이 이룰 수 있는 hairpin 구조 중 stem 부분이 파괴된 mutant들과 base의 치환은 있으나 stem 부분은 다시 회복된 mutant들을 만들었다 in vivo replication assay를 위해 mutation이 일어난 origin 부위를 pAT153 vector로 subcloning하여 COS-1 cell에 transfection함으로써 replication level을 측정하였다. 그 결과 early domain의 inverted repeats는 fuctional cruciform structure를 형성함으로써 SV40 replication에 관여하는 것은 아니라는 것을 알 수 있었다. To define the roles of the early palindrome domain within the SV40 replication origin region involved in initiation of DNA synthesis, 800-bp DNA fragment containing the simian virus 40(SV40) origin of replication was inserted into filamentous phage M13 DNA. Four kinds of mutants were introduced into this recombinant phage DNA, M13SV-2, by oligonucleotide-directed site-specific mutagenesis. Then, the origin fragments containing one or two base substitutions were subcloned into pAT153 vector, a derivative of pBR322. In two mutants (pATSV-A,-B) the stems were destroyed by single base substitutions. In the other two mutants(pATSV-C,-D) the normal stems were restored by additional base substitutions which complements the bases altered initially. While pATSV-A and pATSV-C could tolerate base substitutions, pATSV-B and pATSV-D showed dramatic decrease in DNA replication.

The data wiping is a technique which perfectly deletes data in a storage to prevent data recovery. Currently, management of stored data is important because of increasing an accident of personal information leakage. Especially, if you need to discard data contained personal information, using a wiping tool which permanently deletes data to prevent unnecessary personal information leakage. The data wiping is also used for data security and privacy protection. However the data wiping can be used intentionally destruction of evidence. This intentionally destruction of evidence is important clues of forensic investigation. This paper demonstrates the methods for detecting the usage of wiping tools in digital forensic investigation. 완전삭제 기술은 저장장치 내 데이터를 복구가 불가능하도록 흔적 없이 완벽하게 삭제하는 기술이다. 최근 개인정보 유출 사고가 급증함에 따라 저장된 데이터의 관리가 중요해지고 있다. 특히 개인정보가 포함된 데이터를 폐기해야 하는 경우, 데이터를 영구적으로 삭제하는 완전삭제 도구를 사용함으로써 개인정보에 대한 불필요한 유출을 막을 수 있다. 또한 완전삭제 기술은 데이터 보안 및 프라이버시 보호 측면으로 활용 가능하다. 그러나 완전삭제 기술은 의도적으로 사건과 관련된 증거를 인멸하기 위해 사용될 수도 있다. 이러한 의도적인 증거 인멸은 사건 수사에 있어서 중요한 실마리가 될 수 있다. 본 논문에서는 디지털 포렌식 수사 과정에서 완전삭제 도구의 사용 흔적을 확인할 수 있는 방안을 제시한다.

김연수,김상균,황의경,Kim, Yeon-soo,Kim, Sang-kyun,Hwang, Eui-kyung 대한수의학회 2001 大韓獸醫學會誌 Vol.41 No.2
Amplified fragment length polymorphism(AFLP) technique is based on the polymorphism detection through selective PCR amplification of restriction fragments from digested genomic DNA and thus includes the procedures of the total DNA digestion by endonucleases, ligation of adapters to the ends of the fragments, and following the selective amplification of the restricted DNA fragments. This study were aimed to : (1) determine the genetic variability of S aureus strains, (2) estimate genetic diversity within and among these strains, (3) compare phylogenetic relationships among these strains as genetic markers using AFLP techniques. Genomic DNA was digested with a particular combination of three restriction enzymes with specific recognition sites and the DNA fragments were ligated to restriction specific adapters and amplified using the selective primer combinations. In the S aureus strain, the number of scorable AFLP bands detected per each primer combination varied from 29 to 102, with an average of 61.59 using 27 primer combinations. A total of 1,663 markers were generated, 904 bands of which were polymorphic, showing a 33.48% level of polymorphism with these primer combinations. Among the primer combinations, E02/T02, E02/T03, E04/H02, E02/T01 and E04/H03 primer combinations showed a high level of polymorphism with 0.78, 0.76, 0.74, 0.71 and 0.70, respectively. But T03/H01, E01/T02 and E01/T03 primer combinations showed a low level of polymorphism with 0.38, 0.37 and 0.15, respectively, Therefore, the former primer combinations will be the most effective for AFLP analysis of S aureus. In SA1 sub-types the level of polymorphism of S aureus KCTC 1927 was similar to that of S aureus CU 01(0.825) and higher than those of other strains such as S aureus CU 02 (0.715), S aureus KCTC 2199(0.625), S aureus KCTC 1916(0.607) and S aureus KCTC 1621 (0.553). In SA2 sub-types the level of polymorphism of S aureus CU 07 was similar to that of S aureus CU 08(0.935) and higher than those of both S aureus CU 04(0.883) and S aureus CU 05(0.883) and lower than those of S aureus CU 03(0.583). In SA3 subtypes the level of polymorphism of S aureus CU 11 was similar to that of S aureus CU 12(0.913) and lower than that of S aureus CU 15(0.623). The results proved that AFLP marker analysis of S aureus strain could be used to study the epidemiology of mastitis and in addition, common genotype in geographic region could be useful for the development of an effective vaccine or DNA marker for easy diagnosis of mastitis caused by S aureus infection.

A field survey of fascioliasis of Korean native cattle raising and raised in specialized commercial breeding farms and local farms in Kangwon province using both intradermal test and sedimentation technique for feces was carried out from November to December, 1996. Fecal samples were taken from fascioliasis positive cattle by the intradermal test for the fecal examination. Liver tissues were randomly collected from an abattoir for histopathological examination of liver fluke infection in cattle. The results are as follows. 1. By the intradermal test for a total of 211 cattle raising in both Wonju and Wheongsung, Kangwon province, 60 heads(28.4%) showed positive reaction. Among 60 positive cattle, eggs of Fasciola hepatica were found from 51 heads(85.0%) by sedimentation technique. 2. According to the cattle raising areas, the positive rates by the intradermal test were 26.7%(20 out of 75 heads) in Wonju and 29.4%(40 out of 136 heads) in Wheongsung. 3. According to the age of cattle examined, the positive rates by the intradermal test in 1~3, 4~6 and 7~10 years old were 11.7%(7 out of 100 heads), 68.3%(41 out of 93 heads) and 20.0%(12 out of 18 heads), respectively. 4. The overall infection rates of fluke larvae from the slaughtered cattle at an abattoir in Wonju was 24.7%(37 out of 150 heads). In histopathology, liver lesions were observed such as inflammation with infiltration of eosinophils, polymorphonuclear cells, mononuclear cells and multinucleated giant cells, proliferation of connective tissues, calcification and abscess formation.

Nerogenic tumor of various histologic types may arise in the posterior mediastinum. Mediastinal schwannoma is a frequent paraspinal neurogenic tumor, but malignant mediastinal schwannoma is rare tumor which is derived from Schwann cells. Although there are some reports dealing with approach for screening patients with symptoms suggesting malignancy and the imaging criteria for distinguishing malignant from benign schwannoma but the results are not clearly defined. We present a case of hugh mediastinal schwannoma which was taken for malignancy in imaging studies because of its invasiveness.
