Although pandemic community-associated (CA-) methicillin-resistant Staphylococcus aureus (MRSA) ST30 clone has successfully spread into many Asian countries, there has been no case in Korea. We report the first imported case of infection caused by this clone in a Korean traveler returning from the Philippines. A previously healthy 30-yr-old Korean woman developed a buttock carbuncle while traveling in the Philippines. After coming back to Korea, oral cephalosporin was given by a primary physician without any improvement. Abscess was drained and MRSA strain isolated from her carbuncle was molecularly characterized and it was confirmed as ST30-MRSA-IV. She was successfully treated with vancomycin and surgery. Frequent international travel and migration have increased the risk of international spread of CA-MRSA clones. The efforts to understand the changing epidemiology of CA-MRSA should be continued, and we should raise suspicion of CA-MRSA infection in travelers with skin infections returning from CA-MRSAendemic countries.

Tuberculosis is one of the most common opportunistic diseases in human immunodeficiency virus (HIV)-infected patients in Korea and extra-pulmonary infections are frequently observed in those patients. Cutaneous miliary tuberculosis is a rare form of tuberculosis presented by a papulopustular eruption and hematogenous dissemination of Mycobacterium tuberculosis to multiple organs, which was previously reported among progressed HIV-infected patients. We report the first case of cutaneous miliary tuberculosis which developed as a manifestation of immune reconstitution inflammatory syndrome (IRIS) after initiating antiretroviral therapy (ART).

We implemented a carbapenem-saving strategy in hemato-oncology patients from 2013, using an empirical combination of piperacillin-tazobactam and amikacin for high-risk hemato-oncology patients with febrile neutropenia, who remain hemodynamically unstable > 72 hours despite initial cefepime treatment. All-cause mortality was not different between the two periods (6.54 and 6.57 deaths per 1,000 person-day, P = 0.926). Group 2 carbapenem use significantly decreased after strategy implementation (78.43 vs. 67.43 monthly days of therapy, P = 0.018), while carbapenem-resistant gram-negative bacilli did not show meaningful changes during the study period. Our carbapenem-saving strategy could effectively suppress carbapenem use without an increase of overall mortality.
CACB를 적용한 다중 반송파 CDMA전송방식에 관한 연구
고재훈,홍인기 경희-다반 ASIC 설계교육센터 2005 경희-다반 ASIC센터 논문집 Vol.6 No.-
차세대 무선통신에서 수백 Mbps의 다양한 전송률을 갖는 멀티미디어 서비스를 지원하기 위하여 다중 부호 전송 방식을 적용한 다중 반송파 시스템(Multi-Code Multi-Carrier CDMA : MC- MC- CDMA)이 제안되었다. 본 논문에서는 MC-MC-CDMA가 갖는 단점 중 하나인 높은 PAPR(Peak to Average Power Ratio)문제를 해결하기 위하여 다중 부호 방식 대신 CACB(Constant Amplitude Coding for Bi-orthogonal)를 적용하였다. 또한 CACB가 가지는 파형부호화(waveform coding)효과로 인한 성능향상과 다중 경로 페이딩환경에서 MC-COMA와의 성능비교를 통하여 CACB MC-CDMA가 가지는 주파수 다이버시티 이득을 BER로 분석하였으며 그 수율 (throughput)을 비교, 분석하였다.
이주자의 개인적 연결망과 시티즌십: 여성 결혼이민자의 개인적 연결망의 유형과 결정 요인 분석
고재훈 전북대학교 사회과학연구소 2022 지역과 세계 Vol.46 No.2
본 연구는 전라북도 여성 결혼이민자의 개인적 연결망을 유형별로 구분하고 그 특성을 확인하는 것이 연구의 목적이다. 이를 위하여 여성 결혼이민자의 개인적 연결망의 구조적 특성과 상호작용적 특성을 중심으로 유형화를 시도하였다. 본 연구에서는 ‘2015년 전북다문화가족 실태조사’ 자료에 포함된 여성 결혼이민자 5,347명을 대상으로 개인적 연결망의 내용과 구조를 분석하고 그 결정 요인들을 규명하였으며 유형화를 시도해보았다. 분석 결과 집락분석을 통하여 여성 결혼이민자의 개인적 연결망은 한국가족형, 동족가족형, 동족타인형, 비동족타인형, 지원기관중심형의 다섯 개 유형으로 분류되었으며, 거주기간, 학력, 한국어 실력, 남편 학력, 가족결정권, 가구소득, 부부불화, 자녀 유무, 시부모 동거 여부, 도시 거주 여부, 출신국에 따라 연결망의 유형에 차이가 있었다. 이러한 결과는 여성 결혼이민자의 개인적 연결망 유형이 향후 여성 결혼이민자를 설명하는 패턴 중심 접근법(pattern centered approach) 변수이자 소속되기(belonging) 실천의 변수로서 여타 피설명변수에 대한 적용에 활용될 것으로 기대한다. This study aims to identify the social network types of female marriage immigrants and to identify differences among types by social network. the current study examines the composition and structure of personal networks of female marriage immigrants and their determinants and then cluster-analyze the female marriage immigrants' personal networks. Data from 'A Survey on Multicultural Families in Jeollabuk-do 2015' was used for analyzing 5,347 female marriage immigrants in Jeollabuk-do, Korea. The results showed that social network type of female marriage immigrants were divided into five groups which were ‘Korean Family’, ‘Original Family’, ‘Ethnic Alters’, ‘Alters’, ‘Civil Society Actors’ focused type. There were differ in social network type by female marriage immigrants' general characteristics. These results are expected to be utilized in the application to explanatory variables as a variable for the pattern centered approach to explain female marriage immigrants and a variable of the practice of belonging.
Cyanuric Chloride 잔기를 갖는 ${\beta}-Cyclodextrin$ 유도체의 합성과 섬유 방향가공에의 응용
고재훈,박윤철,김진우,김영호,Ko, Jae-Hoon,Park, Yoon-Cheol,Kim, Jin-Woo,Kim, Young-Ho 한국섬유공학회 2007 한국섬유공학회지 Vol.44 No.4
[ ${\beta}$ ]-Cyclodextrin derivative containing cyanuric chloride moiety (${\beta}CD-CC$) was synthesized by a reaction of ${\beta}-cyclodextrin\;({\beta}CD-CC)$ with cyanuric chloride in alkaline condition. FT-IR and UV spectra along with the results of elemental analysis indicated that cyanuric chloride was bound to ${\beta}CD$. Remaining monochlorotriazine group in ${\beta}CD-CC$ was expected to be used as a reactive site for cellulosic fibers. The ${\beta}CD-CC$ could be used as a host material for inclusion complex of various guest molecules. As an example, vanillin, a flavoring agent in foods and others, was included in the ${\beta}CD-CC$ to make a perfume inclusion complex. UV analysis showed that the vanillin-included complex of ${\beta}CD-CC$ released vanillin more slowly than vanillin itself, which reveals that it can be used as a feasible fragrant finishing agent for textiles.
