저자들은 임신중반기에 3차례의 태아수종으로 자궁내 태아사망을 경험한 임부의 4번째 임신에서 IgG anti-M이 이 임부의 연속적인 태아수종의 원인임을 알게되어 이를 문헌고찰과 함께 보고하는 바이다. Erythroblastosis fetalis resulting from anti-M antibody seems to be and extremly rare phenomenon. Generally, anti-M is regarded as a naturally occurring cold agglutinin. However, there have been several reports of the presence of anti-M, which was of IgG class and caused incompatibility between mother and child. Cases of neonatal anemia and intrauterine death have also been reported. We have experienced a case of anti-M antibody as a cause of intrauterine death and reported that with a brief review of related literatures.

배동한,정한국,김민관,서수형,신영우,조태승 대한부인종양 콜포스코피학회 1993 Journal of Gynecologic Oncology Vol.4 No.3

It has been reported that there are some differances between malignant and benign tumor in the wave form of the intratumoral or surface arterial blood flow. Transvaginal Doppler ultrasound with color flow imaging was used in 24 women with ovarian tumor before explorative laparotomy. The impedence of wave forms were analysed using values nf pulsatility index (PI). Transvaginal sonographic (TUS) scoring system and CA 125 were also checked before operation. The sensi tivity of Pl was 100%, compared with those of TVS scoring system (75%) and CA 125 (63%) even though the specificity of PI (81.3%) was less than those of TVS scoring system (87.5%) and CA 125 (93.8%). But, in the early stage of cancer the sensitivity of PI (100% ) is quite higher than those of TVS scoring system (60%) and CA 125 (40%). Based on the results transvanginal Doppler color flow imaging may he a useful clinical tool in the differential diagnosis of malignant, ovarian tumor.

Eu3+이 첨가된 Gd2O3 구형 형광체의 제조 및 광학적 특성

배동현,장기완,이호섭,서효진,조신호 한국물리학회 2013 새물리 Vol.63 No.8

Catalyst free Gd2O3:Eu3+sphere phosphors were prepared by using hydrolysis method, and their structural & optical properties were investigated. Their structural and morphological features were analyzed by using X-ray diffraction (XRD) and Field-emission scanning electron microscopy (FESEM). The photoluminescence properties of the Eu3+-doped Gd2O3 spheres were studied by using a spectrophotometer to measure their excitation and emission spectra. The X-ray diffraction profiles showed that all peaks could be attributed to the cubic phase which is in good agreement with the standard JCPDS (86-2477) card. FE-SEM indicated that the morphology of the phosphor sphere had with an outer diameter of about 500 nm. We also observed a strong charge transfer band in the excitation spectrum of Eu3+-doped Gd2O3-sphere phosphors, which quenched at Eu3+ concentrations over 7 mol%. We also recorded the emission spectra of Eu3+-doped Gd2O3-sphere phosphors at excitation wavelength of 254 nm. The results showed all the characteristic transitions of the Eu3+ dopant ion, along with a high-intensity peak at 613 nm which corresponded to the 5D0-7F2 transition. 가수분해법을 응용하여 별다른 촉매없이 Gd2O3:Eu3+구형형광체를 제조하고 결정구조와 광학적 특성에 대하여 연구하였다. 제조된시료의 결정구조 및 형상은 XRD, FE-SEM을 이용하여 분석하였으며,광활성제로 첨가된 Eu3+의 광학적 특성은 여기 및 발광스펙트럼등의 측정을 통하여 분석하였다. XRD 분석을 통하여 Gd2O3결정에대한 표준 JCPDS와 제조된 시료에 대한 주요 피크들이 잘 일치함을관찰할 수 있었고, 이들로부터 Eu3+가 첨가된 Gd2O3:Eu3+ 시료는입방 구조임을 확인하였다. FE-SEM을 이용해 측정한 결과, 직경이 약 500nm 정도인 구형모양이었다. 전하이동밴드에 의한 여기효율은 구형의Gd2O3 모체에 첨가된 Eu3+의 농도가 7%일 때에 가장 좋았다. 또한 254 nm의 여기파장으로 시료를 여기하여 Eu3+에 기인한발광스펙트럼을 측정한 결과, 전형적인 Eu3+에 기인한 발광특성을보였으며, 모든 천이들 가운데에 5D0-7F2 천이에 해당하는613 nm 에서 발광세기가 가장 강하였다.

배동한,장경택,선우재근,최규연,도효신 대한산부인과학회 1998 Obstetrics & Gynecology Science Vol.41 No.1

Forty five women with symptomatic uterine myomas, who had already been treated with GnRH agonist as outpatietns in Obstetrics and Gynecology of Chunan Hospital, S.C.H University from March 1995 to February 1997, were retrospected and analyzed about effect and side-effects of GnRH agonist with the results over statistical method of the pelvic ultras onography and the hormone check level in blood. The clinical study was aslo examined and studied alleviation maintenance of symptoms, degree of regrowth, and its final future for treatment. Used GnRH agonist types were Decapepty1, Leuprolide and Nafarelin, and the results of the study is as follows. 1. Size of uterine myomas of forty two(93.3%) among forty five women treated with hormone for six months showed reduction of volume as 42.8 ± 4.4% of the first-size except three(p < 0.0005). Twenty seven(60%) among forty five women could undergo easy operation and had less complications like bleeding. And the rest fifteen(33.3%) among eiteen women(40%) could get satisfactory effects only with GnRH agonist therapy. We changed GnRH agonist type for the rest three women(6.7%) after six months and it was decided the case that treatment effect was low. 2. There were no significant regression in serum LH and FSH(p > 0.05), but serum Estradiol levels fell significantly 4 weeks after first therapy(148.7 ± 20.5pg/ml to 29.7 ± 19.5pg/ml) till 24 weeks (to 17.9 ± 0.9 pg/ml)(p < 0.005). 3. Clinical symptoms due to uterine myomas decreased or disappeared 4∼8weeks after first therapy. 4. From 4 weeks after the last GnRH agonist treatment, Estradiol level was 25 ± 14.8pg/ml and showed gradual increase, and volume of the reduced myoma uteri increased gradually from 42.8 ± 4.4% at the last therapy to 49.6 ± 2.7% 8 weeks after last therapy(p < 0.005). 5. The most common side effect was hot flush(82.2%) and the others included vaginal dryness(37.8%), fatigue and interest decline(46.7%), headache and insomnia(33.3%). However, symptoms like general weakness weight loss and osterporosis were rare, and there was no case to stop treatment due to these symptoms. And these symptoms were disappeared with resumption of menstruation after the therapy. 6. There were potential advantages of GnRH agonist therapy before myomectomy or total abdominal hysterectomy such as; (1) easier and safer to isolate the myomas; (2) less intraoperative blood loss; (3) less complications after myomectomy or total abdominal hysterectomy. 7. GnRH agonist used in this study includes Decapeptyl, Leuprolide and Nafarelin, and there was no difference for effect and side-effects of each type. Considering the above results, GnRH agonist treatment for myoma uteri is regarded to be effective, but more further study and report is desirable for new hormone replacement therapy to prevent regrowth of myoma uteri after treatment stop and estrogen dependent side-effect in treatment.

Clinical Outcome of Paraclinoid Internal Carotid Artery Aneurysms After Microsurgical Neck Clipping in Comparison with Endovascular Embolization

배동현,김재민,원유덕,최규선,정진환,이형중,김충현 대한뇌혈관외과학회 2014 Journal of Cerebrovascular and Endovascular Neuros Vol.16 No.3

Objective : Because of the complex anatomical association among vascular,dural, and bony structures, paraclinoid internal carotid artery (ICA)aneurysms remain a major challenge for vascular neurosurgeons. Westudied the clinical outcomes of 61 paraclinoid ICA aneurysms after microsurgicalclipping in comparison with endovascular coiling. Materials and Methods : Between January 2008 and December 2012, wetreated 61 paraclinoid ICA aneurysms created by surgical clipping or endovascularcoiling. Preoperative neurologic status and postoperative outcomewere evaluated using the Glasgow coma scale (GCS) and themodified Rankin scale (mRS). Postoperative hydrocephalus and vasospasmwere reviewed using the patients' medical charts. Results : Most patients were in good clinical condition before the operationsand had good treatment outcomes. Clinical vasospasm was observedafter the operation in five patients, and hydrocephalus occurred insix patients. No statistically significant difference regarding aneurysm size,sex, GCS score, H-H grade, and mRS was observed between the surgicalclipping group and the endovascular coiling group. In addition, the treatmentresults and complications did not show statistically significant differencein either group. Conclusion : Surgical occlusion of paraclinoid ICA aneurysms is difficult;however, no significant differences were observed in the treatment resultsor complications when compared with coil embolization. In particular, useof an adequate surgical technique may lead to better outcomes thanthose for coil embolization in the treatment of large and/or wide-neckparaclinoid ICA aneurysms.

Q방법론을 활용한 주거복지 종사자의 주거복지 인식 차이

배동학(Bae, Dong Hak),이한나(Lee Han Na),김승희(Kim, Seung Hee) 한국주거환경학회 2021 주거환경(한국주거환경학회논문집) Vol.19 No.1

본 연구는 주거복지 종사자에게 Q 방법론을 적용하여 주거복지 종사자들의 주거복지 인식에 대한 주관적인 개념을 실증적으로 분석하였다. 주거복지 종사자의 주거복지에 대한 인식은 4개 유형으로 도출되었다. 1유형은 물리적 주거환경 개선형, 2유형은 주거복지 정책지원형, 3유형은 광의의 주거서비스 지원형, 4유형은 ‘주거권’ 보장을 위한 주거복지 실현형이다. 이러한 분류는 결국 주거복지 개념과 서비스의 범위에 대한 인식의 차이에서 도출된 것으로 보인다. 주거복지의 개념을 협의로 인식하는가(2유형), 광의로 인식하는가(4유형)에 따라 유형이 분류되었다. 또한, 주거서비스의 범위를 물리적 시설개선에 한정하는가(1유형), 주거 취약계층에 대한 상담·발굴·심리·정서적 서비스까지 포함하여 인식하는가(3유형)에 따라 분류되었다. 이는 주거복지업무 종사자의 업무에 대한 이해와 수행 정도에 따라 개인의 인식이 다르게 나타난 것으로 판단된다. 장기적인 관점에서 주거복지 업무는 주거안정과 주거수준 향상을 위한 수단임을 고려하면, 주거복지 종사자의 주거복지에 대한 인식이 넓은 의미로 확장될 필요가 있다. 주거복지 종사자는 물리적 주거서비스, 경제적 주거서비스는 포함 시키고 있으나 생활의 편리함을 유지할 수 있는 생활서비스 개념은 업무 범위에 포함 시키지 않았다. 이에 전반적인 주거복지 업무에 대한 인식의 제고가 필요하다. 또한, 인식의 차이마다 복지업무의 실천이나 문제해결이 상이 하게 나타날 수 있으므로 전문성 제고를 위한 교육 및 실천방안이 달라져야 할 것이다. This study empirically analyzed the subjective concept of residential welfare workers perception of residential welfare by applying the Q methodology to residential welfare workers. The perception of residential welfare of residential welfare workers was derived into four types. The first type is the physical housing environment improvement type, the second type is the residential welfare policy support type, the 3 type is the broader type of housing service support type, and the 4 type is the realization type of residential welfare to guarantee the right to live. This classification seems to have been derived from differences in perception of the concept of residential welfare and the scope of services. The types were classified according to whether the concept of residential welfare was recognized as a consensus (type 2) or a broad sense (type 4). In addition, it was classified according to whether the scope of residential services is limited to physical facility improvement (type 1), and whether it includes counseling, discovery, psychological, and emotional services for the vulnerable (types 3). It is judged that individuals perceptions differ depending on the degree of understanding and performance of the work of the residential welfare worker. Considering that residential welfare work is a means of improving housing stability and housing standard from a long-term perspective, it is necessary to expand the awareness of housing welfare workers in a broad sense. Residential welfare workers include physical housing services and economic housing services, but the concept of living services that can maintain the convenience of life is not included in the scope of work. Accordingly, it is necessary to raise awareness of overall residential welfare work. In addition, since the practice of welfare work or problem-solving may appear differently for each difference in perception, education and action plans for enhancing professionalism should be changed.
