신나영,공예진,김수인,이충환,백금문,김호성 (사)한국방사선산업학회 2020 방사선산업학회지 Vol.14 No.4

Since MLC used in VMAT is a stepped shield, leakage dose may occur between theleaves. In this study, we compared the skin doses of VMAT treatment plan with Jaw Trackingapplied to CT image obtained using phantom and VMAT treatment technology plan withoutJaw Tracking, and confirmed the usefulness of Jaw Tracking method. We intend to present adirection that can reduce patient exposure due to leakage dose of MLC. As a result, when the JawTracking method was used, the skin dose was reduced by 2.00 cGy on average, and the skin dosewas reduced by 3% compared to the Fixed Jaw method. As a result, when using the Jaw Trackingmethod with VMAT, the leakage and transmission radiation generated between the MLCleaves are reduced, and radiation treatment with a protective effect on the skin is possible whencompared with the case using Fixed Jaw.

범죄청소년과 일반청소년의 심리적 및환경적 특성의 차이:메타분석 연구

신나영 아시아교정포럼 2023 교정담론 Vol.17 No.2

This study conducted a meta-analysis comparing psychological and environmental characteristics of juvenile offenders and non-offenders. Of the 84 papers extracted from the DBPia, Kiss, and Riss search databases, 53 papers met the inclusion criteria of the study. It was found that aggression and antisocial traits showed the large magnitude of effect size and self-control, parent-child communication, impulsiveness and parental conflicts showed moderate effect size. There was no significant difference in effect size between groups in self-esteem, sociability, borderline personality traits, and stress in school. These results suggest that high level of aggression and antisocial traits may be the psychological characteristics that differentiate delinquent from non-delinquent youth. 비행청소년의 심리적 특성에 대한 이해는 범죄 예방을 위한 개입 전략의 수립에 중요하다. 본 연구는 보호처분이나 형사처벌을 받은 범죄청소년과 일반청소년의 특성(가정요인, 학교 및 친구요인, 개인요인)을 비교 조사한 선행연구들의 결과를 통합하여 메타분석을 통해 두 집단 간 특성의 차이에 대한 효과크기를 조사하였다. DBPia, Kiss, Riss 검색 데이터베이스에서 2023년 1월까지 국내 학술지에 발표된 논문 84편을 추출하여 기준을 충족하는 53개 연구에 대해 메타분석을 실시하였다. 분석 결과, 범죄청소년과 일반청소년 간 차이의 효과크기가 가장 큰 변인은 공격성(.94), 반사회적 성향(.91), 자기통제력(-.75) 이었고, 부모-자녀 의사소통(-.66), 충동성(.60), 부모간 불화(.58) 등이 중간 수준의 효과크기로 나타났다. 반면, 자아존중감, 사회성, 경계성 성격 성향, 부모로 인한 스트레스 수준, 학교 스트레스 등은 집단 간 차이가 유의하지 않았다. 이러한 결과는 공격성과 반사회적 성향, 자기통제능력, 부모-자녀 소통의 어려움, 부모간 갈등 등이 일반청소년과 범죄청소년 간에 두드러진 차이를 보이는 심리적 및 환경적 특성이며, 재비행 예방을 위해 이들 요인을 타겟으로 하는 개입이 효과적일 수 있음을 시사한다.

관계적 겸손 척도의 한국어판 타당화 연구

신나영,임영진 한국재활심리학회 2019 재활심리연구 Vol.26 No.1

This study examined the factor structure, test-retest reliability, internal consistency, and concurrent validity of the Korean version of the Relational Humility Scale (K-RHS) in a sample of 361 married participants. Exploratory factor analysis indicated that the K-RHS had a four-factor structure including global humility, accurate view of self, absence of grandiosity, and absence of entitlement. The test-retest reliabilities of the K-RHS subscales ranged from .63 to .93. Internal consistencies of K-RHS subscales ranged from .71 to .92. The K-RHS total score correlated .56 with a measure of forgiveness, .50 with a measure of helping behavior, and .52 with a measure of marital satisfaction. The results of the current study suggest that the K-RHS is a psychometrically sound tool for assessing four subscales of relational humility.

한국판 Beck Anxiety Inventory의 요인구조: 이중요인 탐색적 구조방정식 모형의 적용

신나영 한국청소년학회 2021 청소년학연구 Vol.28 No.8

This study was aimed to examine the factor structure of the Beck Anxiety Inventory (BAI) in Korean university students. To investigate the optimal factor structures of the BAI, 1,645 university students in Seoul and Gyeongbuk area participated in the study. Confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), bi-factor CFA, and bi-factor ESEM were used for data analysis. It was found that a bi-factor ESEM model with four specific factors and a general anxiety factor had the best model fit Among 13 factor models. The results suggest the bi-factor structure of the BAI in Korean university students and the unique value of ESEM in understanding the factor structure of the BAI. 본 연구는 한국판 Beck Anxiety Inventory(BAI)의 요인구조를 살펴봄에 있어 선행연구들에서 사용된 탐색적 요인분석(EFA) 방식과 확인적 요인분석 방식(CFA)의 약점을 극복한 탐색적 구조방정식 모형(ESEM)을 활용해 모형들의 적합도를 비교 분석하여 최적의 요인구조를 확인하고자 하였다. 또한 BAI 전체문항의 총점을 사용하는 것이 타당한지를 살펴보기 위해 이중요인(bi-factor) 모형을 분석에 포함하였다. 서울지역과 경북지역 대학생 1,645명이 연구에 참여하였다. 선행연구들의 결과에 기반해 CFA 모형, ESEM 모형, 이중요인 CFA 모형, 이중요인 ESEM 모형 등 총 13개 모형을 수립하고 적합도를 분석하였다. 분석 결과, 이중요인 ESEM 모형이 CFA 모형과 이중요인 CFA 모형, ESEM 모형에 비해 전반적으로 더 나은 적합도 지수를 보였으며, 요인들 간의 상관강도도 보다 약하였다. 이는 BAI 문항들이 특수요인과 함께 1개의 일반요인에 동시에 수렴되며, BAI 총점을 사용하는 것이 타당함을 시사한다. 본 연구는 ESEM 방식을 적용해 BAI 요인구조를 조사한 첫 번째 연구로, BAI의 요인구조를 이해하는 데 있어 ESEM 방식이 유용함을 보여주었다.

메티실린 내성 황색포도알균(Methicillin Resistant Staphylococcus aureus, MRSA)의 분자역학 연구에서 IRS-PCR (Infrequent- Restriction-Site PCR)의 응용

신나영,유진홍,박철민,이동건,최수미,권재철,김시현,박선희,최정현 대한감염학회 2011 Infection and Chemotherapy Vol.43 No.5

Background: We investigated the usefulness of infrequent-restriction-site polymerase chain reaction (IRS-PCR) compared with pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) on the molecular epidemiologic analysis of methicillin-resistant Staphylococcus aureus (MRSA). Materials and Methods: We used fifty clinical isolates of MRSA collected from 10 university hospitals located in Seoul. We performed three procedures on these isolates: PFGE using Sma I, IRS-PCR using XbaI-Hha I or Eag I-Hha I, and MLST using seven house-keeping genes. We determined the clusters of molecular types by dendrogram using the unweighted pair group method with arithmetic mean (UPGMA) and Dice coefficients Results: MLST analysis showed that isolates exhibited ST1, ST5, ST72, ST89, and ST239. In PFGE, the isolates clustered into 5 major groups with 80% similarity,which subsequently became classified into 18 subgroups with 95% similarity. In IRS-PCR using EagI-HhaI restriction enzymes, there was little resolution among the patterns of isolates. However, Xba I-Hha I IRS-PCR showed 5 groups with a 90%similarity. These groups were then classified into 9 subgroups with a 95% similarity. There were no significant differences among the isolates from different hospitals. Conclusions: The XbaI-Hha I IRS-PCR method could be a useful tool in the molecular epidemiology of MRSA. Its resolution power was good enough to analyze isolates, because the patterns of IRS-PCR were closely correlated with those of MLST and showed diverse groups.

신나영,정경미 한국재활심리학회 2009 재활심리연구 Vol.16 No.2

Children who have intellectual disability usually have difficulties in learning basic number concept. The difficulties are caused by their characters and inappropriate instruction although they are in need of special instructions. There are three recommended learning principles to children with mental retardation. such as direct instruction. CSA(Concrete-Semiconcrete-Abstract) method, emphasizing experience in number. These principles and Applied behavioral analysis were used for teaching abstract number sense by using concrete materials to a child with mild intellectual disability. 9 materials(coloring, wooden blocks, clips, fingers, magnetic fishing game, stamps, animal stickers, peg play, magnet) were used as independent variables and the abstract number task was used as dependent variable. Treatment components used in this program were prompts, positive reinforcement, DRO(differential reinforcement of zero responding), extinction, and using an AB-design, the performance rate of task was compared. The percentage of successful performance has increased to 95.6% in basic number concept task. Additionally, now he can add and subtract within 20, which he was not able to do at the beginning.

Diffuse Interstitial Infi ltrative Lung Metastasis of Malignant Melanoma: a Case Report

신나영,홍유진,김아현,심효섭,남지은,이혜정,김명준 대한영상의학회 2011 Korean Journal of Radiology Vol.12 No.2

A diffuse interstitial infi ltrative pattern of lung metastasis in a patient with malignant melanoma is rare and can be confused with benign conditions such as pulmonary edema or drug-induced pneumonitis. We experienced a case of diffuse interstitial infi ltrative lung metastasis in malignant melanoma in a 37-year-old man. This case was confi rmed by a transbronchial lung biopsy. We herein describe the fi ndings on CT and positron emission tomography scan.

The Differential Imaging Features of Fat-Containing Tumors in the Peritoneal Cavity and Retroperitoneum: the Radiologic-Pathologic Correlation

신나영,김명진,정재준,정용은,최진영,박영년 대한영상의학회 2010 Korean Journal of Radiology Vol.11 No.3

There are a variety of fat-containing lesions that can arise in the intraperitoneal cavity and retroperitoneal space. Some of these fat-containing lesions, such as liposarcoma and retroperitoneal teratoma, have to be resected, although resection can be deferred for others, such as adrenal adenoma, myelolipoma, angiomyolipoma, ovarian teratoma, and lipoma, until the lesions become large or symptomatic. The third group tumors (i.e., mesenteric panniculitis and pseudolipoma of Glisson’s capsule) require medical treatment or no treatment at all. Identifying factors such as whether the fat is macroscopic or microscopic within the lesion, the origin of the lesions, and the presence of combined calcification is important for narrowing the differential diagnosis. The development and widespread use of modern imaging modalities make identification of these factors easier so narrowing the differential diagnosis is possible. At the same time, lesions that do not require immediate treatment are being incidentally found at an increasing rate with these same imaging techniques. Thus, the questions about the treatment methods have become increasingly important. Classifying lesions in terms of the necessity of performing surgical treatment can provide important information to clinicians, and this is the one of a radiologist’s key responsibilities.

비행청소년에 대한 심리학적 개입 프로그램의 효과 : 메타분석 연구

신나영 아시아교정포럼 2021 교정담론 Vol.15 No.1

비행청소년에 대한 개입은 청소년 개인의 웰빙과 재범 및 성 인기 범죄 예방을 위해 중요하다. 본 연구는 우리나라 학술지에 발표된 비행청소년에 대한 심리학적 개입 연구들을 통합해 메타 분석을 수행함으로써 개입의 효과를 체계적으로 분석하고자 하 였다. DBPia, KISS, RISS 검색 데이터베이스를 통해 2020년 9 월까지 국내 학술지에 발표된 논문을 검색하였다. 검색된 62편 의 논문들 중 36편이 포함기준을 충족하였다. 각 연구로부터 참 여자 특성, 개입유형, 측정변인, 상담절차 등에 대한 자료를 추출 하였다. 메타분석 결과, 모든 연구들은 집단상담의 형태로 진행 되었으며, 개입의 전반적인 효과크기는 큰 수준이었다(1.10). 예 술치료와 인지행동치료에 기반한 개입이 가장 빈번하게 활용되 었으며, 효과크기는 각각 1.52와 0.87로 예술치료의 효과가 보 다 큰 것으로 나타났다. 자기지각, 공격성, 분노, 사회적 적응, 자 기통제, 우울, 품행문제, 정서조절 등에 대한 개입의 효과크기는 중간에서 큰 수준(0.66-1.91)으로 나타났다. 이러한 결과는 우리나라 비행청소년에 대한 심리학적 개입이 청소년의 내현적 문제 와 외현적 문제 완화에 효과적임을 시사한다. 비행청소년에게 효 과적으로 알려진 다양한 개입들이 우리나라 청소년들에게도 효 과적인지를 살펴보는 향후 연구들이 필요할 것으로 보인다. Psychological intervention for delinquent youth is important both individually and socially. This study was aimed to conduct a meta-analysis of psychological intervention studies on delinquent youth published in Korean journals. Using the DBPia, KISS, and RISS search databases, articles were searched until September 2020. A total of 62 studies were identified, of which 36 studies met inclusion criteria. The results showed that the overall effect size of the intervention was large (g=1.10). Art therapy and cognitive behavioral therapy have been used most frequently, and the effect sizes of these interventions were 1.52 and 0.79 respectively with the greater effect in art therapy. The effect sizes of intervention on self-perception, aggression, anger, social adaptation, self-control, depression, and behavioral problems of delinquent youth were found to be moderate to large (0.66-1.91). These results suggest that psychological interventions are effective to reduce internal and external problems of Korean juvenile offenders.
