기독교 청소년이 지각한 부모갈등이 진로태도성숙에 미치는 영향: 불안의 매개효과를 중심으로
최나래,신선임 한국기독교상담심리학회 2019 한국기독교상담학회지 Vol.30 No.1
The purpose of this study is to investigate whether anxiety plays a mediating role in relation to parental conflict as perceived by Christian adolescences and career attitude maturity. 240 high school students from 15 protestant churches located in the Seoul–Gyeonggi region were surveyed. The data was analyzed by Baron and Kenny(1986)’s 3 steps of mediating effect. The result of the study was revealed that anxiety exited a partial mediating effect in the relationship between parental conflict perceived by Christian adolescences and career attitude maturity. Through the results of the above study, it was verified that anxiety was one of the predictors of career attitude maturity. This suggests that parental conflict perceived by Christian adolescences and emotions of anxiety are important in the process of maturing the attitudes of Christian adolescences towards their future career path. 본 연구는 기독교 청소년들이 지각한 부모갈등과 진로태도성숙 간의 관계에서 불안감이 매개역할을 하는지 검증하는 데 그 목적이 있다. 이를 위하여 2016년 7월부 터 한 달 간 서울, 경기지역 15개 교회에 출석하는 고등학생 240명의 자료를 분석하였다. 자료분석은 Baron과 Kenny(1986)의 3단계 매개효과 절차에 따라 매개효과를 검증하였다. 그 결과, 기독교 청소년이 지각한 부모갈등과 진로태도성숙 간의 관계에서 불안은 부분매개효과를 가지는 것으로 나타났다. 이는 기독교 청소년이 지각한 부모의 갈등은 진로태도에 영향을 미칠 뿐만 아니라, 부모갈등으로 인해 불안이 증가될 수 있고 이는 진로태도성숙을 저해할 수 있음을 시사한다. 이와 같은 결과를 바탕으로 연구의 시사점, 상담을 위한 제언 및 제한점을 논의하였다.

This study attempted to test the hypothesis that Korean evaluators can score L2 speech appropriately, even when speech rate features are unavailable. Two perception experiments―preliminary and main―were conducted sequentially. The purpose of the preliminary experiment was to categorize English-as-a-foreign-language (EFL) speakers into two groups―advanced learners and lower-level learners―based on the proficiency scores given by five human raters. In the main experiment, a set of stimuli was prepared such that the speech rate of all data tokens was modified to have a uniform speech rate. Ten human evaluators were asked to score the stimulus tokens on a 5-point scale. These scores were statistically analyzed to determine whether there was a significant difference in utterance production between the two groups. The results of the preliminary experiment confirm that higher-proficiency learners speak faster than lower-proficiency learners. The results of the main experiment indicate that under controlled speech-rate conditions, human raters can appropriately assess learner proficiency, probably thanks to the linguistic features that the raters considered during the evaluation process.
DIR 영상을 이용한 피질두께 측정: GRAPPA 인자 2를 이용한 비교
최나래,남윤호,김동현 대한자기공명의과학회 2010 Investigative Magnetic Resonance Imaging Vol.14 No.1
목적 : 본 논문에서는 DIR 영상을 이용하여 두뇌의 피질두께측정 연구를 수행하는 한편 평행 영상기법 중 하나인 GRAPPA (generalized autocalibrating partially parallel acquisitions)를 이용하여 GRAPPA 인자 (reduction factor, R)가 2일 때와 평행 영상기법을 이용하지 않았을 때의 결과 비교를 통해 3D DIR 영상의 획득시간 단축 가능성을 제시하고자 한다. 대상 및 방법 : 3.0T 자기공명영상장치 (Siemens Tim Trio MRI scanner)의 3D DIR 펄스열을 이용하여 6명(남자 3명, 여자 3명, 25.33±2.25살)의 정상인 뇌에 대한 3차원 영상을 얻었다. GRAPPA 시뮬레이션은 R=2 일 때를 가정하여 수행되었고 두뇌 피질두께측정을 위해 Analyze 9.0과 Freesurfer v.4.3.0 프로그램을 사용하였다. 결과로 얻은 데이터를 T-검증을 이용하여 비교분석 하였다. 결과 : GRAPPA 기법을 통하여 복원한 영상이 잡음이 증가하는 경향을 보였으나 두뇌 피질두께 측정에는 별다른 영향을 미치지 않았다. 통계분석을 통해 비교한 결과 대부분의 두뇌 영역에서 참조영상과 GRAPPA 기법을 이용한 영상의 차이가 유의하지 않았다. 결론 : 피질두께측정 연구에 있어서 3D DIR영상의 문제점 중 하나는 긴 영상획득시간이다. 따라서 평행영상 기법 중 하나인 GRAPPA 영상기법을 적용하면 피질두께측정 연구결과의 큰 차이없이 영상 획득 시간을 단축시킬 수 있다.
Optimization of detection of black queen cell virus from Bombus terrestris via real-time PCR
최나래,정철의,이대원 한국응용곤충학회 2015 Journal of Asia-Pacific Entomology Vol.18 No.1
The bumblebee, Bombus terrestris, plays an important role as one of alternative pollinators since the outbreak of honeybee colony collapse disorder. Recently, pathogens and parasites such as viruses, bacteria and mites affecting the life span and fecundity of their host have been discovered in B. terrestris. In this study, in order to detect viral infection in B. terrestris, we collected B. terrestris adults and isolated total RNA for diagnostic PCR. The PCR primers specific for pathogenic viruses were newly designed and applied to gene amplification for cloning and detection. Capsid protein gene of black queen cell virus (BQCV) among examined viral genes was only successfully amplified from collected bumblebee adults and sequenced. To optimize the detection of capsid protein gene of BQCV, 4 regions in the capsid protein gene were selected and further analyzed in quantitative realtime PCR (qRT-PCR). The qRT-PCR analysis revealed that capsid protein gene was directly detected with below 200 ng total RNA. This result suggests that an optimized detection via qRT-PCR can be applied for the rapid and sensitive diagnosis of BQCV infection in the field population as well as risk assessment of B. terrestris.

Personal service robots, a type of social robot that has emerged with the aging population and technological advancements, are undergoing a transformation centered around technologies that can extend independent living for older adults in their homes. For older adults to accept and use social robot innovations in their daily lives on a long-term basis, it is crucial to have a deeper understanding of user perspectives, contexts, and emotions. This research aims to comprehensively understand older adults by utilizing a mixed-method approach that integrates quantitative and qualitative data. Specifically, we employ the Van Kaam phenomenological methodology to group conversations into nine categories based on emotional cues and conversation participants as key variables, using voice conversation records between older adults and social robots. We then personalize the conversations based on frequency and weight, allowing for user segmentation. Additionally, we conduct profiling analysis using demographic data and health indicators obtained from pre-survey questionnaires. Furthermore, based on the analysis of conversations, we perform K-means cluster analysis to classify older adults into three groups and examine their respective characteristics. The proposed model in this study is expected to contribute to the growth of businesses related to understanding users and deriving insights by providing a methodology for segmenting older adult s, which is essential for the future provision of social robots with caregiving functions in everyday life.

Often, abscesses in the orofacial region are of odontogenic origin. Odontogenic abscesses should be treated with caution, since they can have a severe or even fatal course. Because infratemporal space abscesses are located in the deep facial space and the clinical symptoms of this condition are similar to those of temporomandibular joint disorder (TMD), early differential diagnosis is difficult. Herein, we report a case of infratemporal space abscess that was misdiagnosed as TMD at the initial diagnosis and discuss relevant information in the literature on infratemporal space abscess.
