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.

한국판 자기자비척도의 요인구조: 대학생을 대상으로

신나영 서강대학교 학생생활상담연구소 2018 人間理解 Vol.39 No.2

The Self-Compassion Scale (SCS) is the most frequently used questionnaire to assess self-compassion. Previous studies investigating the factor structure of the SCS yielded inconsistent results. The present study was aimed to examine the factor structure of the SCS comparing 8 different factor structures—the unidimensional, six-factor, higher-order factor, two-factor, four-factor and 3 types of bi-factor models—in a sample of Korean college students (N=1,294). The results showed that the bi-factor model comprised of 6 specific factors (i.e., self-kindness, common humanity, mindfulness, self-judgment, isolation, over-identification) and general factor (i.e., self-coldness) demonstrated the best fit to the data. All other models did not satisfy goodness-of-fit. Our findings suggest that the factor structure of the SCS may differ across cultures. 이 연구의 목적은 우리나라 대학생을 대상으로 한국판 자기자비척도의 요인구조를 검토하는 것이다. 경북지역 대학생 1,294명을 대상으로 한국인에게 적합한 자기자비척도의 요인구조를 탐색하기 위해 선행연구들에서 제안되거나 도출되었던 8가지의 대안모형에 대해 확인적 요인분석을 실시하였다. 연구 결과, 국외 연구에서 보고된 것과는 다른 이중요인 모형만이 적합도 기준에 부합하였다. 26개 자기자비척도 문항들은 자기자비의 6개 구성요소인 자기친절, 보편적 인간성, 마음챙김, 자기비판, 고립, 과잉동일시 요인에 각각 수렴되었다. 동시에 26개 문항 중 자기비판, 고립, 과잉동일시 관련 문항들은 ‘자기냉담’이라는 일반요인에도 수렴되었다. 이 연구결과는 우리나라 대학생에게서 나타나는 자기자비척도의 요인구조가 다른 나라 사람의 요인구조와 다름을 시사하며, 우리나라 대학생에게 자기자비척도를 실시할 때 주의할 필요가 있음을 보여준다.

신나영,임영진 한국청소년학회 2019 청소년학연구 Vol.26 No.6

This study was aimed to test the fit of the bi-factor models of the Korean version of the Mental Health Continuum-Short Form (MHC-SF) in Korean university students. To investigate the optimal factor structures of MHC-SF, 3,001 university students in Gyeongbuk area participated in the study. We analyzed 7 factor models including bi-factor models which have been suggested or derived in previous studies. The results showed that the bi-factor model showed the best fit in comparison with the 1, 2, and 3 factor structures. It was found that the bi-factor model comprised of 3 specific factors – emotional well-being, psychological well-beling, social well-being– and 1 general factor (only including the items of psychological and social well-being subscales) - eudaimonia - demonstrated the best fit to the data. All other models did not satisfy the goodness-of-fit. Our results were inconsistent with those reported in other countries, suggesting that the factor structure of MHC-SF may be different for Korean college students and that caution is needed in using the total score of MHC-SF. 이 연구의 목적은 대학생을 대상으로 한국판 정신적 웰빙척도의 이중요인모형의 적합도를 검증하는 것이다. 대학생 3,001명을 대상으로 정신적 웰빙척도의 최적의 요인구조를 탐색하기 위해 이중요인모형을 포함해 선행연구들에서 제안되거나 도출되었던 7가지 대안모형에 대해 확인적 요인분석을 실시하였다. 분석 결과, 국외 연구결과와 유사하게 1, 2, 3요인구조에 비해 이중요인모형의 적합도가 가장 우수하게 나타났다. 14개 문항으로 구성된 정신적 웰빙척도의 문항들은 정신적 웰빙을 평가하는 3개 소척도인 정서적 웰빙, 사회적 웰빙, 심리적 웰빙 요인에 각각 수렴되는 동시에, 사회적 웰빙과 심리적 웰빙 관련 문항들은 ‘유대모니아’라는 일반요인에도 수렴되었다. 이는 국외에서 보고된 이중요인모형과는 다른 것으로, 정신적 웰빙척도의 요인구조가 우리나라 대학생에게서 다르게 나타날 수 있으며 정신적 웰빙척도의 총점을 활용함에 있어 주의가 필요함을 시사한다.

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.

Acupuncture, herbal medication, herbal fumigation and washing, herbal integration, herbal external application, and manual therapy were performed for the treatment of plantar fasciitis in China. In particular, studies on acupuncture, herbal fumigation and washing, and manual therapy were actively conducted and all of these treatment methods were effective. Conclusions Various Chinese medical interventions are being studied in China for the treatment of plantar fasciitis. However, in order to reinforce evidence for effectiveness of treatment, additional high-level clinical studies are required. It is considered that additional research related to the Korean medicine treatment for plantar fasciitis is needed in the future in Korea.

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.

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.

Psychometric Properties of the Bergen Social Media Addiction Scale in Korean Young Adults

신나영 대한신경정신의학회 2022 PSYCHIATRY INVESTIGATION Vol.19 No.5

Objective The aim of this study was to examine the psychometric properties of the Bergen Social Media Addiction Scale (BSMAS) in Korean young adults.Methods A total of 401 Korean university students (mean age±SD, 21.9±1.8 years; female, 72.8%) participated in the study. They completed the Korean version of BSMAS, the Social Network Site Addiction Proneness Scale (SAPS), and the Social Network Site Use Motives Scale. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted in half-split samples to assess the construct validity of the BSMAS. Internal consistency, test-retest reliability, and convergent validity were examined.Results Both EFA and CFA supported a unidimensional model of the BSMAS. Indices of test-retest reliability at a 3-week interval (r=0.75) and internal consistency (Cronbach’s alpha=0.86) of the BSMAS were acceptable and convergent validity between the BSMAS and the SAPS (r=0.86) was satisfactory.Conclusion The results of this study suggest that the BSMAS is an effective tool for screening social network site (SNS) addiction in Korean young adults and is a psychometrically sound measure that can be used in future Korean research on SNS addiction.
