The purpose of this study was to suggest the applicable factors for making safe campus focused on the CPTED. In order to do that, the questionnaire survey and the observation survey were conducted in the 3 universities in Jin-Ju. This study was processed as follows : first, the analyses of the relations among the variables such as satisfactory and important rate about the physical factors for crime prevention, fear of crime, and crime experienced rate. ; second, comparing analyses the questionnaire survey and the observation survey results among the universities. Followings are the results. : 1) the crime experienced rate was 25%, and the theft and breakage were happened frequently. The hotspots were lecture rooms, dormitories and parking lots. 2) as the fear of crime was higher, the satisfaction of crime prevention was lower. The unsafe places were promoted the fear of crime were basement floors, toilets, green zones, sidewalks and parking lots, etc. 3) the factors caused the fear of crime were insufficient lightings and CCTV, and blind spots among the buildings. 4) the important things for the making crime-free campus were the natural surveillance and access control focused on the CPTED. Especially, it was founded that the access control methods were more effective at indoor spaces and individual buildings, and the natural surveillance methods were more important outdoor spaces.

Hye Yun Gwon,나동규,노병주,Wooyul Paik,윤소진,최수정,신동록 대한영상의학회 2020 Korean Journal of Radiology Vol.21 No.5

Objective: To determine the malignancy risk of isolated macrocalcifications (a calcified nodule with complete posterior acoustic shadowing) detected on ultrasonography (US) and to evaluate the postoperative American Thyroid Association (ATA) risk stratification of malignant tumors manifesting as isolated macrocalcifications. Materials and Methods: A total of 3852 thyroid nodules (≥ 1 cm) of 3061 consecutive patients who had undergone biopsy between January 2011 and June 2018 were included in this study. We assessed the prevalence, malignancy rate, and size distribution of isolated macrocalcifications and evaluated the histopathologic features and postoperative ATA risk stratification of malignant tumors manifesting as isolated macrocalcifications. Results: Isolated macrocalcifications were found in 38 (1.2%) of the 3061 patients. Final diagnosis was established in 30 (78.9%) nodules; seven malignant tumors were diagnosed as papillary thyroid carcinomas (PTCs). The malignancy rate of the isolated macrocalcifications was 23.3% in the 30 nodules with final diagnoses and 18.4% in all nodules. Among the six surgically-treated malignant tumors, five (83.3%) had an extrathyroidal extension (ETE) (minor ETE 1, gross ETE 4), and two (33.3%) had macroscopic lymph node metastasis. Four (66.7%) malignant tumors were categorized as high-risk tumors, one as an intermediate-risk tumor, and one as a low-risk tumor using the ATA risk stratification. Histopathologically, out of the six malignant tumors, ossifications were noted in four (66.7%) and predominant calcifications in two (33.3%). Conclusion: The US pattern of isolated macrocalcifications (≥ 1 cm) showed an intermediate malignancy risk (at least 18.4%). All malignant tumors were PTCs, and most showed an aggressive behavior and a high or intermediate postoperative ATA risk.

TAS-20K 잠재프로파일분석을 활용한 감정표현불능증 하위 집단 도출 및 심리적 특성 분석

신재은(Jaeeun Shin),윤소진(Sojin Yun),이태헌(Taehun Lee) 대한스트레스학회 2022 스트레스硏究 Vol.30 No.1

본 연구에서는 Toronto 20항목 감정표현불능증 척도(TAS-20)를 사용하여 감정표현불능증의 하위유형이 감정 인식의 어려움(difficulties identifying feelings, DIF), 감정 표현의 어려움(difficulties in describing feelings, DDF), 외부 지향적 사고(externally oriented thinking, EOT) 수준에 따라 몇 개의 잠재집단으로 분류되는지 잠재프로파일분석을 통해 확인하여 각 잠재집단에 속한 개인의 감정표현불능증 특성을 파악하고자 하였다. 분석 결과 총 5개의 잠재 집단이 확인되었으며, DIF, DDF 점수에 따라 집단 구분이 이루어졌다. EOT의 경우 집단 구분에 있어 결정적인 역할을 하지 못했다. DIF, DDF의 점수가 높을수록 우울과 불안 수준이 높았다. DDF 수준은 평균이나 DIF의 수준이 특히 높은 집단(유형2)에서도 우울과 불안 수준이 높아 DIF 요인이 심리적 부적응에 결정적인 역할을 할 수 있음을 제시하였다. Background: The present study aimed to investigate the number of latent groups that can be identified on the basis on the level of difficulties identifying feelings (DIF), difficulties in describing feelings (DDF), and externally oriented thinking (EOT). Methods: DIF, DDF, and EOT are the sub-factors of the 20-item Toronto Alexithymia Scale. Latent profile analysis was performed to identify the subgroups and investigate their properties. A total of 237 Korean university and graduate students were included in the study, and alexithymia subtypes were classified into 5 latent groups. Results: The groups were classified according to the DIF and DDF scores. Furthermore, it was observed that the EOT did not play a role in classifying the groups. The higher the DIF and DDF scores, the higher were the levels of depression and anxiety. The type 2 latent group, which had a unique profile with the highest DIF level and an average DDF level, showed high levels of depression and anxiety. Conclusions: These results suggest that the DIF significantly affects psychological adaptation, thus warranting the consideration of this parameter in counseling and psychotherapy.

Bifactor 모형을 적용한 CES-D 척도의 요인구조 검증

신재은(Jaeeun Shin),이태헌(Taehun Lee),윤소진(So Jin Yun) 대한스트레스학회 2017 스트레스硏究 Vol.25 No.4

본 연구는 기존 연구에서 요인 수와 구조의 불일치 문제가 제기되어 온 Radloff의 CES-D 척도의 요인구조에 대해 Bifactor 모형을 적용하여 검증하고자 하였다. 연구 1에서는 한국복지패널조사에서 축약형 CES-D 척도에 응답한 12,309명을 분석 대상으로 요인구조를 확인하였으며, 연구 2에서는 223명의 대학생 및 대학원생을 대상으로 CES-D-K척도의 요인구조 및 준거 타당도를 분석하였다. 요인구조 분석 시 Bifactor 모형에서 도출 가능한 모형 기반 신뢰도와 일차원 검정 지수 등을 활용해 CES-D 척도의 측정적 속성과 요인구조를 보다 정확하게 평가하고자 하였다. 그 결과 CES-D 척도는 강력한 일반요인을 가지는 단일차원으로서 전체점수(총점)를 사용하는 것이 타당하다는 결론을 제시하였다. Background: The purpose of this study was to examine the factor structure of the Korean version of CES-D scale by applying the bifactor model. Many studies for validating the CES-D scale have supported the four-factor structure. But some studies found that the three factor structure provided a more appropriate solution. Such inconsistency in the number and structure of factors led us to conduct two studies to clarify the structure of dimensionality of the CES-D-K scale. Methods: In study 1, we factor-analyzed the response patterns to the abbreviated CES-D-K scale (11-item, N=12,309) included the Korean Welfare Panel Study. In study 2, we factor-analyzed the data obtained from 223 college and graduate students who responded to the 20-item CES-D-K scale. Correlational analyses were also conducted to investigate criterion validity of the CES-D-K scale with external variables that are theoretically related to depression. The fit indexes of a single-factor model, a four-factors model, and a bifactor model were compared. The Omega coefficients and Explained Common Variance (ECV) were also computed to evaluate the psychometric properties of the CES–D-K scale more accurately. Results: The results showed that the CES-D-K scale has a high value of Omega-Hierarchical for the total score, low values of Omega-Hierarchical for the subscale scores, and a high ECV value. Conclusions: Therefore, we concluded that, as the scale with a strong general factor, the use of the scale score can accomplish the goal of measuring individual differences on the target construct of depression with little to no gain from constructing subscale scores.
