청소년이 인식한 사회경제적 수준과 정신건강 : 사회적 위축의 매개효과
김은서,정슬기 알코올과 건강행동학회 2019 알코올과 건강행동연구 Vol.20 No.2
Objectives: Life satisfaction among Korean youths is the lowest among OECD countries, and the rate of perceived stress, depression, and suicidal thoughts have been increasing steadily since 2015. The general framework for the discussion of mental health problems has been psychological rather than sociological. The purpose of this study is to understand adolescent mental health from a social perspective by examining the effect of perceived socioeconomic status on depression, and examine the mediating role of social withdrawal in the relationship. Methods: The study sample included 1,671 adolescents from the 7th wave of the Korea Child and Youth Panel Survey (KCYPS). The main variables investigated were perceived socioeconomic status, social withdrawal, and depression. Results: Results showed that the lower the perceived socioeconomic status, the higher the level of depression. Lower perceived socioeconomic status increased the level of social withdrawal, and the social withdrawal was found to have a partial mediating effect on the relationship between socioeconomic status and depression. Conclusions: Findings indicates that the perceived socioeconomic status that reflects social rank and relative deprivation has influence on adolescents’ social withdrawal and depression. The study speaks to the importance of social determinants of mental health, and has implications for changing the environment in order to improve the mental health of adolescents.
Determination of Noise Threshold from Signal Histogram in the Wavelet Domain
김은서,이가민,양세정,이병욱 대한전자공학회 2014 전자공학회논문지 Vol.51 No.2
Thresholding in frequency domain is a simple and effective noise reduction technique. Determination of the threshold is critical to the image quality. The optimal threshold minimizing the Mean Square Error (MSE) is chosen adaptively in the wavelet domain; we utilize an equation of the MSE for the soft-thresholded signal and the histogram of wavelet coefficients of the original image and noisy image. The histogram of the original signal is estimated through the deconvolution assuming that the probability density functions (pdfs) of the original signal and the noise are statistically independent. The proposed method is quite general in that it does not assume any prior for the source pdf.

Objective: To report a case of a patient with a psychosomatic disorder who complained of hyperventilation and was treated with oriental medical treatments and emotional freedom techniques (EFTs). Methods: The patient was diagnosed as having a psychosomatic disorder through an interview and several psychological tests, such as the house-tree-person (HTP) and the person in the rain (PITR) tests. We treated the patient with oriental medical treatments that included herbal medications, western medications, moxibustion, cupping, and EFT. Results: After the treatments, the clinical symptoms of the patient were improved. Conclusions: Oriental medical treatments and EFT may be effective treatments for psychosomatic disorders.
공동 주택의 구조벽과 비내력벽의 일체화 효과에 따른 내진 성능 분석

This study was carried out to examine the effect of the presence of non-structural walls in apartment buildings subjected to an earthquake. It was believed that the presence of non-structural walls, which has not been considered in the structural design process, was usually built together with structural walls and this led to significant damages to the apartment buildings in Pohang earthquake, 2017. In this study, a 22-story apartment building was selected and modeled to simulate the seismic behavior due to earthquakes. The story drift, performance point, and compressive strain in the walls were the main parameters to evaluate the seismic performance with the presence of non-structural walls.
『삼국유사(三國遺事)』에 나타난 불전(佛典) 유통 내력
김은서 사단법인한국교수불자연합회 2023 한국교수불자연합학회지 Vol.29 No.2
본고에서는 『삼국유사』에 언급된 경전과 논소 등의 불전을 전수조사하여 목록화하고 불전의 언급 및 인용 방식을 분류하였다. 더불어 그 맥락과 내용을 검토하여 『삼국유사』에 나타난 불전 유통 내력을 정리하였다. 그 결과, 21가지 경전이 68번 언급되었고, 21가지 논소가 28번 언급되어, 총 42가지 불전이 96번 언급되어 있음을 확인했다. 불전의 언급 방식으로는 단순히 경명만을 언급한 경우와 경문을 인용한 경우로 구분할 수 있는데, 경문의 내용을 인용한 것은 총 10회이다. 불전 유통 방식으로는 외국의 사신이나 유학승 등에 의해 불전이 유입된 내용 총 13회, 강론 내력 총 20회, 더불어 8종의 저술이 언급되어 있으며, 또한 수학 내력과 관련하여 불전이나 그 구체적인 내용이 언급된 경우는 총 5회이다. 일연은 수많은 불전에 대한 이해를 토대로 선별한 불전 중 필요한 내용만을 요약 및 발췌하여 인용하였으며, 불전을 유입시키거나, 강론하거나, 저술, 또는 수학하는 법시(法施)의 신행 내용을 통해 보살행을 실천할 것을 권하고자 했던 것으로 보인다. 이상과 같이 『삼국유사』에 언급된 불전들을 목록화하고, 삼국 내에서의 불전의 유통 내력을 살펴보았다. 어느 시기에 어떤 불전이 삼국에 유통되었는가는 곧 고대 한국 불교의 교학 발전사와 연결된다. 그런 의미에서 본 연구는 당시 교학의 유행과 발전을 파악하는 단초가 될 수 있을 것이라 기대한다.
집단 검진에서 발견된 갑상선 우연암종에 대한 임상적 고찰

Background and Objectives: The introduction of highly sensitive imaging techniques has made it possible to detect many non-palpable nodules, or“incidentaloma”in the thyroid. Discovery of these lesions raises concerns about their malignancy, but the optimal strategy for managing these lesions has not been clearly established. This study was designed to evaluate the usefulness of ultrasonographic exam with new diagnostic criteria and presume the value of mass screening for thyroid cancer. Materials and Methods : Mass screening for thyroid cancer were carried out in conjunction with mass screening for breast cancer. The subjects were 630 women aged 30 years or over. Thyroid glands were examined with 10 MHz transducer ultrasonography by one radiologist. Needle aspiration biopsy were performed when suspicious of malignancy under the new diagnostic criteria. Results and Conclusion : The new ultrasonographic criteria to diagnose thyroid cancer provided useful information and ensured more accurate evaluation. 7 cases of thyroid cancer were discovered and successfully managed. It should be further demonstrated that there is sufficient value of mass screening for thyroid cancer to perform it independently despite early cancer detection.
