본 연구는 게이미피케이션을 적용한 수업의 학습효과를 분석하여 학생들의 학업적 자기효능감과 학습 몰입 척도의 변화를 분석하고자 하는 것이다. 이를 위해 게이미피케이션 요소를 교수학습모델을 설계하고 실험집단과 게이미피케이션을 적용하지 않고 수업을 진행한 비교집단 간의 학업적 자기효능감과 학습 몰입 척도의 변화의 차이를 밝히려는데 목적이 있다. 또한 실험집단은 D전문대학에서 실시하고 있는 NCS 직업기초교양 과목인 의사소통능력에 게이미피케이션을 적용하기 위해 다양한 교수학습모델을 적용하였다. 전체적으로 게이미피케이션 요소를 적용한 수업은 `수동적 자기효능감의 경우 학습자가 자신의 의사를 표현하는 상황을 두려워하지 않고 표현하는 부분이 비교집단에 비해 높은 결과를 나타내었다. 하위분류인 학습몰입에서의 학습태도에 대한 분석의 경우 유의미한 차이가 있었다. 학습태도는 수업에 참여하는 실험집단의 차이를 보여주기 때문에 실험 결과가 높게 나타난 것이다. 본 연구는 게이미피케이션을 적용한 학습효과를 통해 학생들의 학습효과를 상승하는데 보탬이 되고자 한다. The purpose of this study is to analyze the learning effects of classes that are applied with gamification to analyze students" academic self-efficacy and changes in their learning flow scales. To this end, the purpose of the program is to design a teaching learning model and explain the difference between the academic effectiveness and the change in the learning flow scale between the experimental group and the comparative group that conducted the class without the application of the gamification. In addition, a variety of teaching learning models were applied to the communication skills of NCS vocational basic training subjects conducted by D colleges. The class that applied the gamification element as a whole showed a higher result than the comparison group, in the case of passive self-efficacy, where the learner expressed his or her opinion and did not fear the situation. There were meaningful differences in the analysis of learning behaviors in subclasses. The study results are high because the study attitude shows the difference between the groups participating in the class. The study aims to help students increase their learning effectiveness through the use of camouflage.

Objectives This study examined the level of depression and anxiety and the related factors, especially the knowledge and attitudes towards dementia, of people caring for a family member with dementia. Methods Data on the demographics, care burdens, and clinical characteristics of dementia patients and their family caregivers were collected. The Center for Epidemiologic Studies Depression Scale (CES-D) and Korean Screening Tool for Anxiety disorders (K-ANX), Dementia Knowledge Scale (DKS), and Dementia Attitudes Scale (DAS) were performed. This study investigated whether depression and anxiety of caregivers differed according to the caregivers, patients, and the burden of caregivers. Multiple regression analysis was performed to investigate the potential factors that may influence the psychological symptoms in family caregivers. Results There were 135 respondents. The scores of CES-D and K-ANX were 19.18±12.05 (probable depression) and 11.48±8.88 (mild anxiety), respectively. There was a significant difference in the degree of depression according to the level of education (F=4.14, p<0.05), the severity of dementia (F=3.63, p<0.05), and cohabitation with patients with dementia (t=2.07, p<0.05). On the other hand, the difference in the degree of anxiety was not significant depending on the stratified potential factors. The degree of depression in caregivers was positively associated with severe dementia (β=0.252, p<0.01) and negatively associated with the DAS score (β= -0.392, p<0.001). Anxiety was only inversely affected by the DAS score (β=-0.369, p<0.001). Conclusion This study shows that family caregivers of people with dementia experience high levels of depression and anxiety, which are influenced by the patient’s severity of dementia and the caregiver’s attitude toward dementia.

홍수미,배상윤 한국디지털정책학회 2018 디지털융복합연구 Vol.16 No.7

This study investigates convergent influence on test anxiety and its association with job seeking stress, academic burnout, self efficacy among health college students in TOEIC class. Data collection was carried out using a self-administered questionnaire from April 3 to April 14, 2017 and the target was randomly selected 291 Health College Students in TOEIC class from 1 college located in J city. Test anxiety was positively correlated with job seeking stress and academic burnout, and it was negatively correlated with self efficacy. With the analysis of covariance structure, we could confirm relationship among job seeking stress, academic burnout, self efficacy and test anxiety. Job seeking stress was more influential on test anxiety than academic burnout and self efficacy. The results of the study indicate that the efforts, to manage these factors, are required to decrease the test anxiety of health college students in TOEIC class. The results are expected to be useful for the development of TOEIC learning curriculum decrease the test anxiety of TOEIC study among health college students in TOEIC class. In the following study, the survey about additional factors of influence on test anxiety will be needed.

다양한 음성을 이용한 자동화자식별 시스템 성능 확인에 관한 연구

홍수기,Hong Soo Ki 대한음성학회 2002 말소리 Vol.43 No.-

High reliability of automatic speaker recognition regardless of voice conditions is necessary for forensic application. Audio recordings in real cases are not consistent in voice conditions, such as duration, time interval of recording, given text or conversational speech, transmission channel, etc. In this study the variation of verification error rate of ASR system with the voice conditions was investigated. As a result in order to decrease both false rejection rate and false acception rate, the various voices should be used for training and the duration of train voices should be longer than the test voices.

SAR 저감을 위한 휴대폰 설계

홍수원,오학태,박천석 한국전자파학회 2001 한국전자파학회논문지 Vol.12 No.3

휴대폰을 개발할 때 설계 단계에서부터 SAR 적합성 시험을 고려할 수 있는 새로운 방법을 제안한다. 이 방법이 가능한 이유는 phantom 과 휴대폰을 실제와 거의 동일하게 모델링 한 1 mm의 고해상도 모델을 사용하여 신뢰성이 검증된 FDTD로 계산하기 때문이다. 제안한 제조공정을 이용하여 SAR 적합성 시험에서 문제가 된 휴대폰의 SAR을 저감시키는 과정을 소개한다. 본 논문에서는 사용시 인제두부로부터 휴대폰 또는 안테나가 멀어지는 형태가 되도록 하므로서 SAR을 저감시켰다. 그러므로, 새로운 모델의 휴대폰을 개발할 때 시제품을 만들어 SAR 적합성 시험을 시행착오를 반복하면서 원하는 특성의 휴대폰을 개발하는 것이 아니라 CAD 디자인, 복사 패턴, SAR 모두를 하나의 공정으로 묶어 컴퓨터 시뮬레이션으로 일괄처리함으로써 개발 효율과 비용 절감을 동시에 이룩하였다. We propose the row method that is able to consider the SAR compliance test from the very beginning step of developing the mobile phone. The reason this new method is plausible is that we adopt the certified FDTD for the reliability of calculation, utilizing 1 mm high resolution model that is to model the phantom and the mobile phone almost identically to the reality. In this paper we introduce the process that will apply the proposed method in order to reduce the SAR of the mobile phone that has been problematic in satisfying the SAR compliance test. It results in dropping in the SAR that we keep the mobile phone or its antenna while we use it. Therefore here we make a claim as fellows. When we develop the new mobile phone, we should use the computer simulation combining the CAD design and radiation pattern rather than make a prototype and then use the trial and error method. Moreover the former way leads us to boost up the developing efficiency and reduce the cost.

Background : This study is aimed to elucidate the developmental pattern of human fetal lip by histological and immunohistochemical examinations. Methods : Totally 231 normal human lip tissues obtained from autopsied fetuses were fixed with 10% buffered formalin, sectioned in cross and longitudinal directions, routinely stained for H&E and performed for immunohistochemistry with antibodies of S-100 protein, proliferating cell nuclear antigen (PCNA), transglutaminase C (TGase-C), metalloproteinase (MMP)-3, MMP-10, tenascin, KL1, K8.12, E-cadherin, tissue inhibitors of matrix metalloproteinase (TIMP)-1, TIMP-2 and total keratin (TK). Results : The lip structure first appeared as an orifice of stomodeum around the 7-8th week of gestation, and a major structure of the midface was observed by the 11-12th week. As the squamous epithelium of the lip became thick and was keratinized, the vermilion border became distinguished in the 15-16th week, and the lip structure was almost completed with the presence of orbicularis oris muscle in the lingual side of vermilion border by the 17-18th week. Immunohistochemically, the vermilion border showed strong reactions for tenascin, E-cadherin and MMP-3 and increased positivity for PCNA, cytokeratins (TK, KL1, K8.12), and TGase-C. Conclusions : With the above findings we suppose that the cytodifferentiation of vermilion border epithelium plays an important role for the development of human fetal lip.
