목적 : 본 연구는 소아, 청소년의 강박 증상을 평가하기 위한 도구인 아동용 예일-브라운 강박척도(Childen's Yale-Brown Obsessive Compulsive Scale : Y-BOCS)의 한국판을 제작하여 그 신뢰도와 타당도를 검증하고자 시행되었다. 방법 : 강박장애로 진단된 42명의 아동과 청소년들을 대상으로 CY-BOCS를 시행하였다. 평가자간 신뢰도를 측정하기 위하여 20명의 환자를 2명의 평가자가 동시에 면담하였다. 수렴타당도와 변별타당도의 검증을 위해 총괄적인 임상 인상척도-강박장애(Clinical Global Impression-Obsessive Com-pulsive Disorder : CGI-OCD). 아동용 Leyton 강박 척도(Lryton Obsessional Inventory-Child Version : LOI-CV), 소아우울척도(Child Depression Inventory : CDI), 소아 상태-특성 불안척도(State-Trait Anxiety Inventory for Children : STAI-C)를 시행한다. 결과 : Cronbach's α값으로 평가한 내적 일치도는 0.86으로 높게 나타났다. CY-BOCS 전체 점수 강박사고, 강박행동 소척도 점수에 대한 군내 내적일치도는 각각 0.94. 0.94. 0.84로 우수한 평가자간 일치도를 보였다. CY-BOCS 전체 점수와 CGI-OCD 점수간의 상관관계는 매우 높게 나타났고(r-0.88), LOI-CY 총점과도 통계적으로 유의한 상관관계(r=0.51)가 관찰되었다. CY-BOCS 전체 점수와 STA-I-C의 상태불안 점수간에는 상관관계가 나타나지 않았고(r=0.25), 특성불안 점수(r=0.43) 및 CDI 점수(r=0.49)와는 유의한 상관관계를 나타냈다. 결론 : 본 연구결과, 한국판 CY-BOCS의 높은 타당도 및 신뢰도가 입증되었으며, 향후 강박 증상의 객관적인 평가 및 정량화를 위해 유용하게 사용될 수 있을 것이다. Objective : This study was carried out to evaluate the reliability and validity of the Korean form of the Children's Yale-Brown Obsessive Compulsive Scale(CY-BOCS). Method : Forty-two children with obsessive-compulsive disorder(OCD)(31 boys and 11 girls, aged 7 to 18 years) were assessed with CY-BOCS. Interrater agreement was assessed by two raters in subsample(n=20). discriminant and convergent validity were assessed by comparing CY-BOCS scores to Clinical Global Impression-OCD(CGI-OCD), Leyton Obsessional Inven-tory-Child Version(LOI-CV), State-Trait Anxiety Inventory for Children(STAI-C), and Child Depression Inventory( CDI ). Results : Internal consistency was high, measuring 0.86 for the 10 items and total score. The intraclass correlations for the CY-BOCS total, obsession, and compulsion scores were 0.94, 0.94, 0.84, suggesting excellent interrater agreement for subscale and total scores. The CY-BOCS total score showed highest correlation with CGI-OCD(r=0.88), and significant correlation with LOI-CV(r=0.51), Trait Anxiety score(r=0.43), and CDI scores(r=0.49), but it was not correlated with State-Anxiety score(r=0.25). Conclusion : The results of this study indicate that the Korean form of CY-BOCS is a reliable and valid scale for rating obsessive-compulsive symptom severity. KEY WORDS : Development · Rating scale · Obsessive-compulsive disorder · Reliability Validity.

This study was focused on developing and obtaining a kimchi starter for use in commercial kimchi production. Kimchi varieties made with selected starters are of high quality, have high levels of mannitol, and extended shelf life. The starters were screened for properties such as mannitol production, low gas/acid production, and acid resistance. Finally, kimchi fermentation testing was performed using selected LAB starters. Kimchi samples were prepared with lactic acid bacteria (LAB) starters, including Leuconostoc mesenteroides PBio03 and Leuconostoc mesenteroides PBio104. The LAB starters are isolated from kimchi and can grow under pH 3.0 and low temperature conditions of 5℃. Four kimchi samples were fermented and stored for 28 days at 5℃. The kimchi samples made with starters (PBio03 and PBio104) had better quality (production of mannitol and maintenance of heterofermentative LAB dominance) than the non-starter kimchi samples. In the starter kimchi, Leu. mesenteroides was the dominant LAB, comprising 80% and 70% of total LAB counts at 7 and 21 days, respectively. Mannitol content of the kimchi with Leu. mesenteroides PBio03 was 1,423 ± 19.1 mg/ 100 g at 28 days, which was higher than that of the non-starter kimchi sample (1,027 ± 12.2 mg/100 g). These results show the possibility of producing kimchi with improved qualities using Leu. mesenteroides PBio03 and PBio104 as starters.

전자선을 이용한 수술중 방사선치료를 위해서는 수술중에 드러내 놓은 종양에 고선량의 방사선을 조사하되 주변 정상 조직을 보존하기 위하여 cone 장치를 개발할 필요가 있으며, 임상에 필요한 자료를 얻는 것 뿐만아니라 콜리메이터에 의한 적정 X-선 창 크기도 정할 필요가 있다. holder와 cone으로 이루어진 알루미늄제 결합형 cone장치를 개발하였다. 광자선의 SSD 100cm에서 조사면 크기가 직경 4~9cm이면서 lcm씩 차이가 있는 28cm 길이의 원통형 cone을 만들였으며, holder는 cone의 직경이 7cm이상인 것과 미만인을 것을 접속시키기 위해 따로 두 개를 만들었다. holder의 측면에는 조사부위를 관찰하기 위한 거울과 조명등을 삽입할 수 있는 개구부를 두었다. cone에 의한 조사면 크기와 콜리메이터에 의한 X선 창의 크기의 여러 가지 결합에 대하여 수중의 전자선의 깊이선량분포독선 및 측방선량분포곡선, 선량분포를 1차원 물팬톰 장치로 조종하는 p-형 실리콘 검출기로 측정하였다. 출력계수도 p-형 실리콘 검출기로 수중에서 측정하였다. 전자선의 에너지와 cone의 크기의 결합이 일정할지라도 콜리메이터에 의한 X-선 창의 크기는 표면선량 및 최대신량점의 깊이, 80% 선량점의 깊이, 측방선량분포, 출력계수에 영향을 미쳤다. 그중, 출력계수의 변화가 가장 현저하였다. 예로서 9 MeV 전자선의 출력계수는 0.637과 1.549의 범위에 있었다. 콜리메이터에 의한 X-선 창의 크기는 수술중 전자선치료용 cone 장치의 벽으로 향하는 산란 전자의 양에 영향을 미치고, cone장치에서 다시 산란된 전자는 출력계수 뿐만 아니라 선량분포도 바꿀 것으로 생각된다. 따라서 수술중 전자선치료용 cone장치에 대한 선량분포 측정은 임상에서 선량의 불확정도를 최소화하기 위해 필수적이다.능적으로 평가되어야 하므로 앞으로 이에 대한 연구가 요구된다.수 있었다. 즉, $a^{*}$ / $b^{*}$ 의 비값이 1이상 흑은 1에 가까울 때는 미숙기, 0.8 부근 일때는 적숙기, 0.8보다 작아 질수록 적숙기에서 과숙기로 점차 옮아감을 알 수 있었다.지해줄 수 있는 문헌들이 충분히 고찰되지 못하였고, 이론적배경 또한 횡문화 이론과의 관련성이 적었다. 또한 횡 문화 연구에 기초가 되는 연구대상자의 사회 인구학적 특성과 역사적 배경은 잘 나타났으나, 이론적 연구와 경험적 연구 간에 괴리가 있었다. 3. 표본추출방법은 문화에 기반을 둔 대상자를 선정한다는 점에서 한계성 이 있었다. 4. 방법론적 이유로는 대상자와의 면담시간이 구체적으로 기술되지 않았으며, 고유한 언어를 통역하는 과정에서 의미론적 문제에 대한 고려가 부족하였다. 면접과 기록과정에서 보면 자료의 기록과정과 분류 및 분석과정이 명시되어 있지 않았다. 참여관찰과 면접방법을 사용시 이에 대한 자세한 기술이 되어 있지 않았다. 5. 연구결과의 적용 및 이에 대한 논의는 상당히 제한되어 있었는데, 수편의 연구만이 방법론 문제점과 앞으로의 연구분야에 대한 전망을 제시하였으며, 특이한 것은 어 떤 연구자도 이른 개발을 위한 적용 및 임상실무적 차원에서 간호에 대한 제언을 하지 않았다.유모델변수들은 유입-유출 자료들로부터 평가할 수 있으며, 이를 위해서 본 논문에서는 Gauss-Newton 방법을 이용한 Bard 알고리즘을 사용하였다. 서울 구로구 시흥동 산사태 발생 지역의 산사면에 대하여 개발된 모델을 적용하여 예제 해석을 수행함으로써, 지하수 흐름 모델이 산사태 For intraoperative radiation therapy using electron beams, a cone system to deliver a large dose to the tumor during surgical operation and to save the surrounding normal tissue should be developed and dosimetry for the cone system is necessary to find proper X-ray collimator setting as well as to get useful data for clinical use. We developed a docking type of a cone system consisting of two parts made of aluminum: holder and cone. The cones which range from 4cm to 9cm with 1cm step at 100cm SSD of photon beam are 28cm long circular tubular cylinders. The system has two 26cm long holders: one for the cones larger than or equal to 7cm diamter and another for the smaller ones than 7cm. On the side of the holder is an aperture for insertion of a lamp and mirror to observe treatment field. Depth dose curve. dose profile and output factor at dept of dose maximum. and dose distribution in water for each cone size were measured with a p-type silicone detector controlled by a linear scanner for several extra opening of X-ray collimators. For a combination of electron energy and cone size, the opening of the X-ray collimator was caused to the surface dose, depths of dose maximum and 80%, dose profile and output factor. The variation of the output factor was the most remarkable. The output factors of 9MeV electron, as an example, range from 0.637 to 1.549. The opening of X-ray collimators would cause the quantity of scattered electrons coming to the IORT cone system. which in turn would change the dose distribution as well as the output factor. Dosimetry for an IORT cone system is inevitable to minimize uncertainty in the clinical use.

본 연구에서 제안된 질감특징분석 알고리즘은 뇌출혈환자의 CT영상을 이용하여 정상영상과 질환영상으로 구분하여, 고유영상(Eigen images) 및 실험영상(test images)을 생성하고 제안된 컴퓨터보조진단(computer aided diagnosis) 시스템에 적용하여 6개의 파라메타로 정량적 분석을 통해 뇌출혈 CT영상의 인식률을 도출하고 평가하였다. 결과로 뇌출혈 CT영상 40증례 중에서 각각의 질감 특징값에 대한 인식률은 평균밝기의 경우 100%, 평균대조도의 경우 100%, 평탄도의 경우 100%, 왜곡도의 경우 100%로 높게 나타났고, 균일도의 경우 95%, 엔트로피의 경우 87.5%로 다소 낮은 질환인식률을 보였다. 따라서 본 연구의 결과를 바탕으로 의료영상의 컴퓨터보조진단 시스템으로 발전된 프로그램을 구현한다면 뇌출혈 CT영상의 질환부위 자동검출 및 정량적 진단이 가능해 컴퓨터보조진단 자료로서 활용이 가능할 것으로 판단되며 최종판독에서 정확성과 판독시간 단축에 유용하게 사용 될 것으로 사료된다. In this study we proposed a texture feature analysis algorithm that distinguishes between a normal image and a diseased image using CT images of some brain hemorrhage patients, and generates both Eigen images and test images which can be applied to the proposed computer aided diagnosis system in order to perform a quantitative analysis for 6 parameters. And through the analysis, we derived and evaluated the recognition rate of CT images of brain hemorrhage. As the results of examining over 40 example CT images of brain hemorrhage, the recognition rates representing a specific texture feature-value are as follows: some appeared to be as high as 100% including average gray level, average contrast, smoothness, and Skewness while others showed a little low disease recognition rate: 95% for uniformity and 87.5% for ntropy. Consequently, based on this research result, if a software that enables a computer aided diagnosis system for medical images is developed, it will lead to the availability for the automatic detection of a diseased spot in CT images of brain hemorrhage and quantitative analysis. And they can be used as computer aided diagnosis data, resulting in the increased accuracy and the shortened time in the stage of final reading.

1975년 5월부터 1987년 10dnjfRK지 38명의 자궁 체부암환자가 서울대학교 병원 치료방사선과에서 근치적 방사선 치료를 받았다. 이중 32명은 수술 후 방사선 치료를, 1명은 수술 전 방사선 치료를, 5명은 방사선 치료만을 받았다. 전체 환자에서의 비만, 52세 이후의 늦은 월경, 만삭 임신이 없었던 경우, 당뇨병, 고혈압 등의 빈도는 정상 한국 여성들에서의 빈도보다 높았다. 그 중 비만, 당뇨병, 늦은 월경 등의 빈도는 유의하게 높았다. 전체 환자의 5년 생존율은 75.6%였고 FIGO 병기, I, II기 및 III기에서의 생존율은 각각 90.0%, 80.0% 및 44.4%였고 조기병기(I,II기)와 진행병기(III기)의 생존율은 Cox의 다변량 분석법으로 분ㅅ헉한 결과 유의한 차이가 있었다. 자궁 체부암으로 사망한 것이 확인 된 8예 중 원발병소의 치유실패나 재발로 인한 경우가 2예, 원격전이로 인한 경우가 3예, 두 가지 동반된 경우가 3예였다. 자궁 체부암 I,II기는 방사선 치료와 수술등의 국소적 치료방법으로 중증의 부작용없이 양호한 치료 성적을 얻었으나 III기에서는 더 적극적인 치료가 필요할 것으로 생각된다. From May, 1979 to October 1987, 38 patients with endometrial carcinoma were treated with radiotherapy a Seoul National University Hospital. Of these, 32 patients received radiotherapy postoperatively, one' received radiotherapy preoperatively, and five received radiotherapy only . Relative frequencies of obesity, nulliparity, late menopause, diabetes mellitus, and hypertension were all higher than those reported In normal women in Korea, and those of obesity, diabetes mellitus, and nulliparity were significantly high. The overall five-year survival was 75. stage III(10cases) were 90.0%, 80.0% and 44.4%. respectively, and were significantly different from each other. Among various factors, stage only proved to be prognostic by multivariate analysis. There were two local failures, three local failures combined with distant metastasis,. and three distant metastasis. Stages I and II could be adequately controlled by local modalities without severe complications, stage III endometrial carcinoma might need mere aggressive treatment for better survival.

<P><B>Abstract</B></P> <P>The purpose of this study was to investigate the neural correlates of cognitive-behavioral therapy (CBT) for externalizing behavior problems in perpetrators of school bullying using assessments of brain activity and behavior. Twenty-five adolescent bullies participated in an 8-session intervention. Prior to and after participation, 24 adolescents were evaluated using the Child Behavior Checklist (CBCL) and 23 completed resting-state functional magnetic resonance imaging. Changes in the fractional amplitude of low-frequency fluctuations (fALFF) and scores on the CBCL were analyzed. We also compared the identified changes into 2 groups (low and high delinquency) differentiated by a cutoff of 65 points on the delinquency subscale of the CBCL. Following the intervention, participants exhibited improvement in the subscores of the CBCL and decreases in the fALFF of the inferior parietal lobule, lingual, interior frontal and middle occipital gyrus. A positive correlation was observed between changes in the CBCL externalizing behavior scores and fALFF of the inferior frontal gyrus. The high delinquency group showed a greater decrease in delinquency and externalizing CBCL subscores across time than did the low delinquency group. The high delinquency group had more areas that showed change in fALFF post-intervention than did the low delinquency group. A positive correlation was observed between changes in the CBCL delinquency scores and fALFF of the precentral gyrus in the high delinquency group. The results indicate that this CBT for externalizing behavior problems in bullies had more positive effects on delinquent behavior in adolescents with high levels of delinquency, and these changes were associated with functional changes in brain activity.</P> <P>Trial registration: ClinicalTrials.gov identifier: NCT02670876 </P> <P><B>Highlights</B></P> <P> <UL> <LI> School bullying is a universal phenomenon that has significant negative effects on mental health for both the perpetrator and victim. </LI> <LI> We conducted cognitive-behavioral therapy targeting cognitive distortions related to externalizing problems commonly found in bullies. </LI> <LI> The purpose of this study was to investigate the effects and neural correlates of this intervention on externalizing problems. </LI> <LI> We found a positive effect on externalizing problems and this was associated with changes in spontaneous neural activity in related brain regions. </LI> <LI> Further studies that include large homogeneous samples and well-controlled designs are warranted. </LI> </UL> </P>

A 60-year-old man presented with pain on the left cheek and lateral nose. The patient had been diagnosed with facial herpes zoster in the left V2 area 6 months previously. Medical treatment was prescribed for 6 months but it had little effect. We blocked the left infraorbital nerve under ultrasound guidance, but pain relief was short term. Therefore, we performed pulsed radiofrequency treatment on the left infraorbital nerve under ultrasound guidance. Six months after the procedure, the reduction of pain was still maintained, and there was no need for further management. (Korean J Pain 2013; 26: 84-88)
