고재훈,문송미 대한의학회 2018 Journal of Korean medical science Vol.33 No.39

To evaluate methicillin-resistance (MR) rates among community-associated (CA) Staphylococcus aureus infections in the Korean military, we screened electronic medical records of 223 patients with S. aureus infection in a military referral hospital from 2012 to 2017. During the study period, MR rates did not change annually, and were not different between officers and conscripted personnel. Among conscripted personnel, MR rates in CA S. aureus infections did not increase with longer duration of military service, both in trend analysis and multivariate analysis. In conclusion, MR rates among CA S. aureus infections did not increase during military service in Korea.

Shielding Analysis of Dual Purpose Casks for Spent Nuclear Fuel Under Normal Storage Conditions

고재훈,박제호,이강욱,백창열,김태만 한국원자력학회 2014 Nuclear Engineering and Technology Vol.46 No.4

Korea expects a shortage in storage capacity for spent fuels at reactor sites. Therefore, a need for more metal and/orconcrete casks for storage systems is anticipated for either the reactor site or away from the reactor for interim storage. Forthe purpose of interim storage and transportation, a dual purpose metal cask that can load 21 spent fuel assemblies is beingdeveloped by Korea Radioactive Waste Management Corporation (KRMC) in Korea. At first the gamma and neutron flux for the design basis fuel were determined assuming in-core environment (the temperature,pressure, etc. of the moderator, boron, cladding, UO2 pellets) in which the design basis fuel is loaded, as inputdata. The evaluation simulated burnup up to 45,000 MWD/MTU and decay during ten years of cooling using the SAS2H/OGIGEN-S module of the SCALE5.1 system. The results from the source term evaluation were used as input data for thefinal shielding evaluation utilizing the MCNP Code, which yielded the effective dose rate. The design of the cask is based on the safety requirements for normal storage conditions under 10 CFR Part 72. A radiationshielding analysis of the metal storage cask optimized for loading 21 design basis fuels was performed for two cases;one for a single cask and the other for a 2x10 cask array. For the single cask, dose rates at the external surface of the metalcask, 1m and 2m away from the cask surface, were evaluated. For the 2x10 cask array, dose rates at the center point of thearray and at the center of the casks’ height were evaluated. The results of the shielding analysis for the single cask show thatdose rates were considerably higher at the lower side (from the bottom of the cask to the bottom of the neutron shielding) ofthe cask, at over 2mSv/hr at the external surface of the cask. However, this is not considered to be a significant issue sinceadditional shielding will be installed at the storage facility. The shielding analysis results for the 2x10 cask array showedexponential decrease with distance off the sources. The controlled area boundary was calculated to be approximately 280mfrom the array, with a dose rate of 25mrem/yr. Actual dose rates within the controlled area boundary will be lower than25mrem/yr, due to the decay of radioactivity of spent fuel in storage.

여성 결혼이민자의 한국 이름 짓기의 결정 요인 분석: 사회활동참여와 차별과의관계를 중심으로

고재훈 전북대학교 사회과학연구소 2021 지역과 세계 Vol.45 No.3

Name is one of important factors of her/his social identity. It is also a representative form of practice that reproduces conscious connections to cultural backgrounds or groups. For this reason, names of certain cultural styles are subject to discrimination and exclusion. Sometimes, multiple names can be used according to relationships or situations. In the case of immigrants, the specificity of going through various cultures is added, and even for an individual, the use of names in various cultural style is not rare. So then, the use new names of migrants can be viewed as a process of transnationalism called selective use of multiple names, not a process of assimilation such as rename, name change or giving up name. Therefore, this study analyzes the determinants by presenting variables of civic engagement and discrimination as the main factors of immigrants’ use of the new name in the country of residence. In addition, the relationship between civic engagement and discrimination is identified to verify the mediation effect and to calculate the indirect effect to find out the degree of mediation. It is also tested whether civic engagement moderates the effect between discrimination and the use of the new name in the country of residence. As a result of the analysis, this study finds that civic engagement and discrimination increases the possibility of the use of the new name in the country of residence and that civic engagement increases the risk of discrimination. Furthermore, the partial mediating effect is verified by showing significant indirect effects through the discrimination experience of civic engagement. However, civic engagement does not have the moderating effect on the effect between discrimination and the use of the new name in the country of residence. 이름은 개인의 정체성을 구성하는 중요한 부분이다. 이는 또한 문화적 배경이나 집단에 대한 의식적 연결을 재현하는 관행의 대표적인 형태이다. 이 때문에 특정 문화권 양식의 이름이 차별과 배제의 대상이 되기도 하고, 때로는 관계나 상황에 맞춰 여러 이름을 사용하는 것도 볼 수 있다. 이민자의 경우에는 여러 문화권을 거치는 특수성이 더해져, 한 개인이라 하더라도 여러 문화권 양식의 이름 사용이 흔하게 이루어진다. 이때 이민자의 새로운 이름 사용을 포기나 교체와 같은 동화 과정이 아닌, 여러 이름의 선택적 사용이라는 초국적주의의 과정으로 볼 수 있다. 따라서 이 연구에서는 이민자의 거주국 이름 사용의 주요 요인으로서 사회활동참여와 차별의 변수를 제시하고 그 효과를 검증하여 결정 요인을 분석하고자 하였다. 또한 사회활동참여와 차별 사이의 관계를 밝혀 그 매개 여부를 검증하고 간접효과를 계산하여 매개의 정도를 알아보고자 하였다. 그리고 차별과 거주국 이름 사용 사이의 관계를 사회활동참여가 조절하는지를 검증하고자 하였다. 연구 결과 차별 경험과 사회활동참여 경험이 각각 거주국 이름 사용의 가능성을 높일 뿐 아니라, 사회활동참여 경험이 차별 경험의 위험을 높임을 알 수 있었다. 또한 사회활동참여 경험의 차별 경험을 통한 간접효과가 유의미하게 나타남으로써 부분매개효과가 검증되었다. 그러나 차별과 거주국 이름 사용 사이의 관계를 사회활동참여가 조절하는 효과는 없었다.

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).

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.

Evaluation of a Carbapenem-Saving Strategy Using Empirical Combination Regimen of Piperacillin-Tazobactam and Amikacin in Hemato-Oncology Patients

고재훈,김시호,강철인,조선영,이남용,정두련,백경란,송재훈 대한의학회 2019 Journal of Korean medical science Vol.34 No.2

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.
