황재연(Jae yeon Hwang),안관수(Kwan Su An) 한국홀리스틱융합교육학회 2022 홀리스틱융합교육연구 Vol.26 No.4

이 연구는 청소년을 대상으로 개발된 마음그램 에비척도(2021)의 타당도를 재검증하는 것이다. 안관수(2021)가 개발한 마음그램 예비척도는 7개의 요인 가운데 일부 문항에 오류가 발견되었다. 이 연구는 이러한 점을 보완하기 위해 개발된 마음그램 예비척도의 요인구조와 문항의 구성을 분석하고 신뢰도와 타당도를 재검증하는 데에 목적이 있다. 탐색적 요인분석과 확인적 요인분석에서 사용한 표본은 선행연구에서 수집한 중ㆍ고등학생 280명의 자료를 토대로 검증하였으며, 준거타당도에서는 충남, 전북 지역 중ㆍ고등학생 312명을 대상으로 설문 후 공인타당도를 실시하였다. 그 결과 요인구조는 7요인(인간존중/용서/자기통제/의지력/자율성/수용/이타행동)으로 31문항이며, 요인모형의 적합도는 수용 가능한 것으로 나타났다. 공인타당도 결과 마음그램 척도는 무조건적 자기수용척도, 단축형 자기통제척도, 심리적 안녕감척도, 관용성척도와 유의미한 상관이 있는 것으로 나타났다. This study retests the validity of the preliminary Maumgram scale developed for adolescents. Errors were found from a few of items among seven factor of preliminary Maumgram scale developed by An Gwansu(2021). To correct errors, it aims to retest the reliability and the validity of the scale, by analyzing the factorial structure and the composition of items in it. It examined the sample used for both exploratory and confirmatory factor analysis based on the data of 280 junior high and high school students, collected by a previous study, and tested the concurrent validity, among criteria-related validity, by administering questionnaires to 312 junior high and high school students in Chun-gnam and Jeong-buk. The findings show that the factor structure consists of seven factors (31 items) such as respect for persons, forgiveness, self-control, willpower, autonomy, acceptance and altruism, and the validity of the factor model is acceptable. The concurrent validity was tested to show that the Maumgram scale has significant correlations with the scales of Unconditional self-acceptance, Brief self-control, Psychological well-being, and Tolerance.

The purpose of this study was to develop a self-regulation program for middle school students based on the 'Maumgram' and test the effects of the program. Maumgram is a four-type mind position that usually stays when the basic needs is expressed in a negative way, depending on the state of the mind. This study is to regulates the over-indulge mind type among the four types of Maungram’s. The goal of this program was to improve willpower, a key factor in middle school students' self regulation ability. This program was implemented once a week and consisted of 6 sessions with main themes such as goal setting, self-evaluation, self-strengthening, feedback, and relationship with others. After the preliminary program, pre- and post-tests of self regulation were performed to verify the effectiveness of the program. The results showed that the self-regulation ability improved significantly.

Microstructure Refinement of Pulsed Laser Deposited La0.6Sr0.4CoO3-δ Thin-film Cathodes for Solid Oxide Fuel Cell

황재연,이헌,윤경중,이해원,이종호,송휴섭,손지원 대한금속·재료학회 2013 METALS AND MATERIALS International Vol.19 No.6

In this study, the microstructural modification of pulsed laser deposited La0.6Sr0.4CoO3-δ (LSC64) thin-film cathodes for solid oxide fuel cells (SOFCs) to improve the lateral conduction and to reduce the surface composition degradation is investigated. A high-temperature deposited 100 nm-thick denser LSC64 layer is added over 2.4 μm-thick porous cathode to cover and bridge the cathode domains. According to the cell performance analyses using current-voltage-power measurements, the performance of the cell modified with an additional denser layer is increased compared with the cell without the denser layer in all operating temperature range. The degree of improvement of peak power density is bigger than 10% at 650- 550 °C and is about 6% at 500 °C. This performance enhancement can be attributed to the electrochemical property improvement, especially oxygen surface exchange property, rather than to the conduction improvement, based on the electrochemical impedance analysis. Improved crystallinity and composition integrity of the denser LSC64 layer is considered to enhance the surface exchange property of the cathode.

대중교통과 택시를 통한 이동성 분석 지표 개발

황재연,조신형,박신형 대한교통학회 2023 대한교통학회 학술대회지 Vol.88 No.-

대중교통은 교통 혼잡과 대기 오염, 개인 차량에 대한 의존도를 낮추는 매우 훌륭한 교통 수단으로 자리 잡아왔다. 하지만 대중교통 시설은 경제성, 효율성을 중심으로 노선을 수립하여 지역적인 서비스 수준의 격차가 심화되고 있다. 본 연구에서는 지역간 발생하고 있는 대중교통의 불균형을 평가하기 위하여 대중교통과 택시를 활용한 대중교통 수단경쟁력을 분석하는 지표를 제안하고자 한다. 분석을 위해 스마트카드 데이터와 택시 데이터를 활용하였고, 분석 지표에는 대중교통의 이동성과 운행시간, 환승시간, 운행비율을 고려하여 산출하였다. 분석 결과로 일반적인 생각과 비슷하게 대중교통의 이동성보다 택시의 이동성이 높게 나왔으며, 거리가 멀어짐에 따라 대중교통의 수단경쟁력이 택시와 비슷해졌으며 비슷해졌으며, 이러한 결과값은 택시가 장거리 운행일수록 교통량의 영향을 더 많이 받으므로 추정할 수 있다.

PURPOSES : This study proposes an index for analyzing mobility based on smartcard and taxi data to evaluate imbalances in public transit. METHODS : The proposed mobility index is calculated based on the difference between the mobility indexes of public transit and taxis using the variables of the in-vehicle time, waiting time, and driving ratio. For a more detailed analysis, the distances are divided into short distances, medium distances, and long distances. RESULTS : Public transit mobility indexes are generally evenly distributed, but the taxi mobility indexes are located in the largest legend. When comparing the respective mobilities of public transit and taxis, many areas with a high mobility of taxis (similar to the distribution) exist, especially in the outskirts such as Dobong-gu, Nowon-gu, Gangdong-gu, Guro-gu, Geumcheon-gu, and Eunpyeong-gu. On average, the mobility of public transit according to the distance is smaller in a short distance and higher in a long distance. CONCLUSIONS : The results demonstrate the use of the proposed index for analyzing the basic statuses of complementary indexes for evaluating public transit imbalances. In the future, more detailed results (including socioeconomic variables corresponding to the grid areas) should be studied to identify the impacts of the mobility index.

Retrievable Airway Stent Placement for Stoma Stricture after Anterior Mediastinal Tracheostomy: Case Report

황재연,신지훈,김용희,이연주,송호영,김진형 대한영상의학회 2013 대한영상의학회지 Vol.68 No.6

Anterior mediastinal tracheostomy (AMT) is performed to establish an airway after resection of advanced tumors in the cervicothoracic region. We report a case of successful placement of a covered retrievable self-expandable nitinol stent for a stoma stricture that developed after AMT in a patient with adenoid cystic carcinoma of the trachea. Two stent placements and removals, at two and three months after their initial placement, were performed due to loosening of the stents. Although we did not achieve long-term results as the patient died of massive hemorrhage, the stent placement was both feasible and safe, thus suggesting that temporary stent placement may be a valuable option for treating stoma stricture occurring after AMT.

황재연,윤혜경,김경모 대한소아소화기영양학회 2015 Pediatric gastroenterology, hepatology & nutrition Vol.18 No.3

Pediatric pancreatitis is not uncommon and results in considerable morbidity and mortality in the affected children. Unlike adults, pediatric pancreatitis is more frequently associated with underlying structural abnormalities, trauma, and drugs rather than an idiopathic etiology. Magnetic resonance cholangiopancreatography (MRCP) is a good imaging modality for evaluating pancreatitis and determining etiology without exposure to radiation. This article focuses on MRCP findings associated with various causes of pancreatitis in children, particularly structural abnormalities of the pancreaticobiliary system, as well as describing the feasibility, limitations, and solutions associated with pediatric MRCP.
