Dynamic ultrasonography of the shoulder

박진아,채지원,김동현,차승우 대한초음파의학회 2018 ULTRASONOGRAPHY Vol.37 No.3

Ultrasonography (US) is a useful diagnostic method that can be easily applied to identify the cause of shoulder pain. Its low cost, excellent diagnostic accuracy, and capability for dynamic evaluation are also advantages. To assess all possible causes of shoulder pain, it is better to follow a standardized protocol and to perform a comprehensive evaluation of the shoulder than to conduct a focused examination. Moreover, a proper dynamic study can enhance the diagnostic quality of US, especially when the pathology is not revealed by a static evaluation. The purpose of this article is to review the common indications for dynamic US of the shoulder, and to present the basic techniques and characteristic US findings.

간호대학생의 시뮬레이션 기반 실습교육 후 성찰일지에 대한 내용분석

박진아,홍지연 한국간호시뮬레이션학회 2019 한국간호시뮬레이션학회지 Vol.7 No.1

Purpose: The purpose of this study is to provide basic data for developing strategies to improve the learning effect of simulation by analyzing the reflective journaling after the simulation based learning on the nursing of patients with upper gastrointestinal (UGI) bleeding. Method: From September 19–29, 2016, we conducted a simulation of UGI bleeding patient nursing with fourth-year students in the nursing department of University B in City A, and analyzed the data using content analysis. Results: In this study, reflective journaling can be an effective educational method to strengthen nursing competence, such as the self-reflection of nursing students, evidence-based nursing practice, teamwork, and communication ability. Conclusion: Reflective journaling after practice in simulation-based education is an important process in training critical thinking, situational judgment, and reflection of nursing practice content, and needs to be extended to both on-campus practice and clinical practice.

최근 ITU-R에서는 전파혼신과 밀접한 관계가 있는 무선기기의 RF 항목(주파수허용편차, 점유주파수대역폭, 불요발사 등)에 대한 권고안 SM.1045, SM.328, SM.853, SM.329, SM.1539 등을 제정하거나 개정하였다. 이와 관련하여 본 논문에서는 국내 무선설비규칙의 전파 질 허용치 및 측정방법과 연계하여 ITU-R RF 성능 권고(안)의 핵심내용에 대한 분석결과를 제시하였다. 본 논문의 내용은 무선기기의 인증 및 무선국 검사에 적용되는 국내 무선설비 기술기준치를 이해하는 데 참고자료로 활용될 것으로 기대된다.

사이버공동체와 법

박진아 서강대학교 법학연구소 2022 서강법률논총 Vol.11 No.3

인터넷으로 촉발된 정보혁명은 모바일시대를 거쳐 4차산업혁명으로 새로운 전환점을 맞이하고 있다. 4차산업혁명으로 촉발된 새로운 사회는 한편으로는 인간에게 편리성을 도모하면서 인간을 힘든 노동에서 해방시켜주는 반면에 다른 한편으로는 인간 노동이 AI로 대체되고 인간의 일자리는 줄어들 수밖에 없어 우리에게 새로운 사회문제를 제기하고 있다. 더욱이 코로나 19 팬데믹으로 교육, 직장, 문화 등 각 영역에서 언택트의 팬데믹 경제 체제로 재편되면서 폐업등이 속출하고 양극화가 점점 심화되는 추세에 있다. 이러한 사회적 불안과 모순이 커지고 있는 시점이자 변혁의 길목에서 새로이 사이버공동체가 등장하고 그 사회적 역할이 강화되고 있다. 사이버공동체는 정보사회에서 소외되어 가는 인간들을 구원할 수 있는 유력한 수단인 동시에 위기의 시대에 새로운 사회안전망과 복지의 역할을 수행하는 신주체가 될 수 있다는 관점에서 사이버공동체가 진정한 공동체일 수 있는지, 의사공동체에 머무는지 사이버공동체의 결성과 변화 동향을 살펴보면서, 그 사회적 역할과 그에 따른 법적 의미와 과제를 짚어보고자 한다. 논의 순서는 메타버스(Metaverse)와 블록체인을 활용한 메타버스공동체를 포함한 사이버공동체의 개념 및 유형, 사이버공동체규범, 사이버공동체의 법률관계, 사이버공동체와 그에 관한 법적 도전과 대응의 순으로 살펴보고자 한다.

유아기 어머니의 양육스트레스, 모·자의 심리적응 및 모-자녀관계 관련 연구

박진아 한국아동심리재활학회 2011 놀이치료연구 Vol.15 No.1

본 연구는 인구학적 특성, 어머니와 유아의 심리적응 및 어머니와 자녀의 다양한 관계측면이 어머니의 양육스트레스 고위험군에 어떠한 영향을 미치는 지를 구체적으로 살펴보고자 하였다. 연구대상은 경기 및 충청지역 소재 어린이집과 유치원의 만 2세부터 5세까지 유아 287명(남아 147명, 여아 140명)이었다. 연구도구는 어머니의 양육스트레스, 어머니와 유아의 심리적응, 부모자녀관계 척도를 사용하였다. 연구결과 첫째, 양육스트레스 고위험군과 정상군의 차이를 살펴본 결과 유아의 성별에는 차이가 나타나지 않았으나, 유아의 연령이 높아질수록 양육스트레스 고위험군 어머니가 더 많은 것으로 나타났다. 둘째, 양육스트레스 고위험군 어머니는 정상군 어머니에 비해 더 우울하고 불안하며, 유아는 문제행동을 더 많이 보이고, 모-자녀관계에서도 애착을 더 잘 맺지 못하고, 훈육적이지도 못하면서, 심리적 연류성과 부모효능감은 더 낮고, 자녀와의 관계에서 좌절감을 더 많이 경험하고 있는 것으로 나타났다. 마지막으로, 어머니의 취업유무와 유아의 연령, 어머니의 불안, 유아의 외현화 문제행동, 모-자녀간 애착, 훈육, 관계적 좌절감이 양육스트레스 고위험군에 영향을 미치는 것으로 나타났다. This study examines mental health, parent-child relationship of mothers with high-risk parenting stress and their preschoolers. The targets are 296 preschoolers, ages 3-6 and their mothers. Instruments used in this study were Korean Parenting Stress Index-Short Form, SCL-90R, Korean version of Child Behavior Checklist 1.5-5, Parenting Relationship Questionnaire. Results are follows. First, mothers with older children showed more parenting stress. Second, mothers with high-risk parenting stress were more depressive, more anxious and had more dysfunctional parent-child relationship with their children. Finally, mother's job, children's ages, children's externalizing behavior problem, attachment, disciplinary parenting, and relational frustration were the significant predictors of mother's high-risk parenting stress.

COVID-19에 따른 인식변화가 미용실 이용고객의 위생인식에 미치는 영향

박진아,노영희 한국미용학회 2022 한국미용학회지 Vol.28 No.4

This study conducted a survey of a total of 230 hair salon users in Daejeon, Chungnam, and Sejong and analyzed the results of it in order to find out the effect of changes in perception according to COVID-19 on the perception of hygiene of customers going to hair salons, and the result is the following. First, due to people's risk perception about COVID-19, hygiene to prevent COVID-19 infection has settled in society. Also, awareness of contagious diseases that may occur in hair salons has increased, and in particular, people's interest in respiratory infections has been recorded high. Second, since fears of COVID-19 infection have expanded individual's concept of hygiene from individuals to public places, it was found that more thorough hygiene standards are needed because there are many situations of close contact in hair salons, which are a type of multi-use facilities. Third, it was studied that customers, who feel greater psychological pressure such as stress and depression due to COVID-19, they require stricter hygiene standards as well as washing hands and wearing masks in hair salons. As the result, the need to change customers' perception in using hair salons safely has been raised. And in order to reduce users' concerns about COVID-19 infection and present social stability, it is considered that thorough quarantine, and nationally institutionalized rules and norms are needed, and the media and the press should provide correct information. Follow-up studies are needed to prepare for contagious diseases in various fields of the beauty service industry in the future, and considering that COVID-19 is still going around, periodical studies are required when the pandemic is over.

A Close Link between Metabolic Methionine Pathway and Methylation of Histone 3 Lysine 9 (H3K9)

박진아,김근철 한국유전학회 2008 Genes & Genomics Vol.30 No.1

Chromatin is structurally remodeled by various posttranslational modifications including acetylation, methylation, phosphorylation, and ubiquitination. Among histone modification, methylation reaction is preceded by utilizing S-adenosylmethionine (SAM) of metabolic methionine pathway as a methyl donor in the cells. To examine how dietary methionine pathway is connected with histone methylation, we have treated methionine metabolites and synthetic analogs on the culturing cells. Most of methionine metabolites had no effect on the cell growth, but synthetic analogs of S-adenosylhomocysteine (SAH) showed cell death-related inhibitory effect. Using western blot analysis, we found that dimethylation of histone 3 lysine 9 (H3K9) but not that of H3K4 or H3K36, was specifically reduced by metabolites treatment. However, methylation of H3K9 (di) was restored by withdrawal of the metabolites. When methionine was deprived from culturing condition, H3K9 (di) methylation be decreased, but restored by treatment of metabolites such as SAM or homocysteine. We also obtained specific reduction of H3K9 by metabolites treatment using the immunostaining analysis. Therefore, we suggest that there is a close link between dietary methionine pathway and methylation of H3K9.
