The emergence of antibiotic resistance in Acinetobacter spp. is a rising public health concern worldwide. The objective of this study was to investigate the prevalence of antibiotic-resistance genes and the virulence of Acinetobacter spp. isolated from soil and crops obtained from agricultural fields in South Korea. Eight Acinetobacter spp. isolates carried various antibiotic resistance genes, such as emrAB (100%), cat/craA (100%), and aadA gene (87.5%). Minimum inhibitory concentration (MIC) analysis revealed that strains harboring antibiotic resistance genes exhibited high resistance to the respective antibiotics, such as colistin, chloramphenicol, and streptomycin. Interestingly, most of these isolates had high capability of biofilm formation and swarming motility, along with faster growth rates. Taken together, our study demonstrated that antibiotic-resistant Acinetobacter isolated from agricultural settings in South Korea not only frequently carries antibiotic resistance genes but also has virulence-related traits.

손수민,서동조,남대현,백성현 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1

Metal Organic Framework(MOF)는 금속 이온과 유기 리간드의 결합으로 형성된 결정성 화합물로서, 비표면적이 넓고 기공성이 뛰어난 특성으로 인해 흡착/분리 공정 및 촉매 제조 등의 많은 분야에 활용되고 있다. 이러한 MOF의 응용에 있어 새롭게 연구되는 방법으로, MOF를 고온에서 장시간 처리하여 doped-nanocarbon의 형태로 변화시킨 후 이를 다양한 분야에 적용하려는 사례들이 선보이고 있다. 본 연구에서는 보편적인 MOF 중 하나인 ZIF-8을 기반으로 제조된 Nanocarbon의 물성 및 전기화학적 성능을 평가하였다. 합성된 ZIF-8에 함침법을 이용하여 thiourea를 담지한 후 carbonization 실험을 진행하였다. Carbonization 과정 후 X선 회절분석(XRD)을 진행하여 결정성을 확인하였고, N2 adsorption isotherm 분석을 통해 비표면적 및 세공 구조를 확인하였다. 주사전자현미경(SEM) 및 투과전자현미경(TEM), 광전자분광기(XPS)를 이용하여 시료의 표면 형상과 성분 변화를 관찰하였다. 전기화학적 성능 평가는 RDE(Rotating Disk Electrode)를 이용하여 carbonization 및 N, S doping에 의한 ORR(Oxygen Reduction Reaction) 활성 변화를 비교하였다.

Belsey Mark IV 위바닥주름술은 이전의 역류 방지 수술이 실패하여 재수술을 해야 하는 경우 혹은 식도 열공 탈장이 오래 되어 유착이 있는 경우에 적응증이 된다. 본 증례는 식도 열공 탈장과 GERD로 진단되어 Nissen 위바닥 주름술을 시행하였으나 실패하였고 재수술을 시도하였지만 수술 부위의 유착이 심하여 수술적 접근이 불가능하였다. 저자들은 흉강을 통하여 Belsey Mark IV 위바닥주름술을 실시하였고, 수술 후 증상과 영양상태의 호전을 보인 1예를 문헌 고찰과 함께 보고하는 바이다. Antireflux surgery has been indicated in gastroesophageal reflux disease (GERD) that does not respond to medical treatments. Although the most commonly performed operation is Nissen fundoplication, Belsey Mark IV fundoplication is indicated for more complicated cases, such as, in cases of a failed Nissen operation or a long lasting hiatal hernia. Here, we report a case of Belsey Mark IV fundoplication for a failed Nissen fundoplication. The infant developed frequent times of aspiration pneumonia after initial Nissen for a hiatal hernia with GERD during the newborn period. At 15 months of age, a $2^{nd}$ Nissen operation was attempted, but fundoplication was not available because of excessive mesenteric adherence to the liver and cardia. Therefore, Belsey Mark IV fundoplication was performed via trans-thoracic approach, which can provide full esophageal mobilization and better visualization of the herniated fundus and the surrounding tissues. Subsequently, she has shown an improved general condition without GERD.

Disruption of the Corticoreticular Tract in Pediatric Patients With Trunk Instability: A Diffusion Tensor Tractography Study

손수민,신소민 대한재활의학회 2017 Annals of Rehabilitation Medicine Vol.41 No.6

The authors report the diffusion tensor tractography (DTT) findings of three pediatric patients with gait dysfunction and corticoreticular tract (CRT) disruption. All three patients showed unilateral trunk instability, but they did not show any spasticity or weakness of the distal extremities. Clinical evaluation of trunk instability using a Trunk Control Measurement Scale (TCMS) revealed that the more affected side had a lower score than the contralateral side. DTT showed disrupted CRTs in hemispheres contralateral to the hemiparetic sides, which were associated with unilateral proximal instability, although conventional MRI showed no abnormal lesion explaining the hemiplegic symptom. Compared to the results in age-matched controls, these three patients had decreased values of fractional anisotropy (FA) and tract volumes (TV) of the affected CRTs, and these values were also decreased compared to those in the contralateral side. On the other hand, values of FA and TV of the corticospinal tracts on the ipsilateral and contralateral sides were only marginally different. In conclusion, diffusion tensor imaging can be helpful for investigating the state of the CRT in pediatric patients with trunk instability and gait dysfunction.

사회양극화에 따른 유아교육 양극화 현상에 대한 고찰

손수민 한국생태유아교육학회 2013 생태유아교육연구 Vol.12 No.2

본 연구의 목적은 오늘날 우리 사회에서 문제시 되고 있는 사회양극화와 교육양극화 현상에 대한 이해를 기초로 하여 유아교육의 양극화 현상을 해소하기 위한 방안을 모색하는데 있다. 사회양극화로부터 파급된 교육양극화 현상은 부모의 사회경제적 지위에 따라 유아기 교육에 있어서 극명하게 다른 양상을 드러내고 있다. 유아기 교육에 있어서 사교육의 무분별한 팽창, 과도한 교육비 지출, 교육기회의 지나친 지역 편중화로 인해 교육 기회의 불균등성, 교육격차, 교육비 부담 등의 문제를 파생시켰다. 반면 우리 사회에서 빈곤 유아들은 계속적으로 증가하고 있고 이들은 적절한 교육과 교육환경의 부재로 인해 사회적 위화감과 상대적 빈곤감 등을 경험할 수 있다. 사회양극화로 인한 경제적 불평등이 교육에 있어서의 양극화 현상을 초래하고, 교육양극화는 경제적 불평등을 공고히 하면서 불평등의 구조가 악순환 되는 현상이 나타나고 있다. 그러므로 공교육 강화를 통한 교육기회의 균등성을 제공하고 양극화 현상을 완화시키고 계층이동의 가능성을 열어주는 사다리 역할을 할 수 있는 사회의 개입이 시급한 실정이다. The purpose of this study is to investigate solutions for relieving early childhood educational polarization based on understanding of social polarization as well as educational polarization which are on-going issues in our society. According to the parents’ socioeconomic status(SES), educational polarization addressed different aspects in early childhood education, especially for private education. First, as private education market in early childhood education was outrageously growing, parents’ educational expenses became higher and regional bias to have educational opportunities was obvious. Therefore, inequity and gap in education and parents’ burden on educational expenses have been issues in early childhood eduction. Furthermore, as child poverty has been increasing in our society, children in poverty suffer from lack of educational opportunities, environments, and appropriate care. They also experience atmosphere of social disharmony and relative poverty. Since social polarization and educational polarization were caught in vicious circle, social intervention, which reinforces public education and guarantees equity in education, was needed in early childhood education.

손수민,유진선,박인식 대한재활의학회 2015 Annals of Rehabilitation Medicine Vol.39 No.1

Objective To evaluate the therapeutic effect of botulinum toxin A (BTX-A) injection on spastic gastrocnemius (GCM) and tibialis posterior muscles (TPo) by using the foot pressure measurement system (FPMS).Methods Eighteen ambulatory CP patients were recruited in this study. BTX-A was injected into the GCM at a dose of 6–12 units/kg and TPo at a dose of 4–9 units/kg according to the severity of equinus and varus deformity. Foot contact pattern, pressure time integral (PTI), coronal index using the FPMS and Modified Ashworth Scale (MAS), and visual inspection of gait pattern were used for evaluation of the therapeutic effect of BTX-A injection. Clinical and FPMS data were statistically analyzed according to the muscle group.Results A significant decrease in the MAS score of the GCM and TPo was observed, and spastic equinovarus pattern during gait showed improvement after injection. The GCM+TPo injection group showed a significant decrease in forefoot, lateral forefoot pad, and lateral column PTI, and a significant increase in hindfoot PTI and coronal index. In the GCM only injection group, forefoot PTI and lateral column PTI were significantly decreased and hindfoot PTI was significantly increased. The TPo only injection group showed a significant decrease in lateral column PTI and a significant increase in the coronal index. Change in PTI in the hindfoot showed a significant correlation with the change in MAS score of the GCM. Change in PTI of the lateral column and coronal index showed a significant correlation with the change in MAS score of the TPo. Conclusion The FPMS demonstrated the quantitative therapeutic effect of BTX-A on abnormal pressure distribution in equinovarus foot in detail. The FPMS can be a useful additional tool for evaluation of the effect of BTX-A injection.
