Objectives: The purposes of this study were (1) to determine the reliability of the Korean version of the Scale of Parental Involvement and Self-efficacy-Revised (SPISE-R-K), (2) to examine whether rehabilitation experience and residual hearing level have an impact on parental self-efficacy and their involvement in rehabilitation processes, and (3) to describe the early intervention for young children with hearing loss (CHL) and their caregivers in Korea by analyzing the items in the SPISE-R-K. Methods: We collected 61 SPISE-R-K questionnaires from the caregivers of CHL (mean age= 20.85 months, SD= 7.85; male= 33, female= 28). All children used hearing devices (hearing aid (s) users= 36; cochlear implant (s) users= 25). The reliability of the questionnaire was assessed, and the effects of rehabilitation experience, and children’s residual hearing were examined for the sub-sections of ‘Knowledge’, ‘Confidence’ and ‘Action’. Moreover, the item scores from each section were compared. Results: Cronbach’s α analyses indicated that the SPISE-R-K was reliable in measuring the self-efficacy and involvement of caregivers of CHL. We found that the rehabilitation experience did not show a significant effect on each section’s score whereas residual hearing level had a significant effect on the ‘Knowledge’ section scores. Overall, parents showed higher self-efficacy in items related to auditory access than in items related to language development. Conclusion: The SPISE-R-K is a reliable tool for measuring the self-efficacy and involvement of Korean caregivers of young CHL. We hope that professionals utilize SPISE-R-K to identify the information that needs to be provided to caregivers of young Korean children with hearing loss, making it a valuable tool for early intervention.

본 논문에서는 무인 항공기의 자동 착륙 제어를 위한 카메라 기반의 착륙 지점 인식 알고리즘을 제안한다. 제안하는 알고리즘은 무인 항공기에 탑재된 카메라를 이용하여 착륙 지점을 검출하는 것을 목표로 하기 때문에 적은 계산량이 보장되어야 한다. 제안하는 알고리즘은 마커를 이용하며, 마커 인식을 위하여 이진화 기법, 레이블링 기법, 검증 과정으로 이루어져 있다. 마커를 검출한 후, 안전한 착륙을 위하여 카메라 내부 파라미터를 이용하여 마커 중심과 카메라 간의 실제 거리를 추정하며, 마커와 카메라간의 기울어진 각도를 추정한다. 실제 무인 항공기에 카메라를 탑재하여 제안한 알고리즘의 성능을 확인하였으며, Vicon 센서와 비교를 통하여 제안한 알고리즘의 우수성을 검증하였다. In this paper, the camera based landing site recognition algorithm is proposed for UAV to land autonomously onto landing position. Since this paper focuses on detecting landing site using the camera mounted on the UAV, the proposed algorithm has to guarantee the realtime. The proposed algorithm uses an predefined marker and consists of binarization, labeling and qualification process. After detecting the marker, both the 3-axis distances and slant angle between camera and the marker are estimated using the camera intrinsic parameter for autonomous landing of the UAV. The performance of the proposed algorithm is confirmed through several experiments and the experimental results through comparison of the Vicon sensor demonstrate that the proposed algorithm has superiority.

Recently, studies on mitochondrial DNA (mtDNA) have increased rapidly. Conventional parameters, such as diversity index, pairwise comparison, are used tointerpret and validate data on autosomal DNA; however, the use of these parametersto validate data from mitochondrial DNA databases (mtDNA DBs) needs to be verifiedbecause of the different transmission patterns of mtDNA. This study was done to verifythe use of these conventional parameters and to test the“ coverage concept”for anew parameter. The mtDNA DB is not very big; however, it is necessary to check howthe change in parameters corresponds to the DB size. For this, we artificiallyrearranged a Korean DB into several small sub-DBs of variable sizes. The resultsshow that the diversity in nucleotide variations and the different haplotype numbers donot vary as the size of DB increases. However, the “coverage”changed a lot. Thecoverage increased from 0.113 in a DB of 100 people to 0.260 in a DB of 653 people. Additionally, using the“ coverage concept”, we predicted how the total number of haplotypeschanged with variations in the sub-DB size and compared the predicted resultwith final result. In conclusion,“ coverage”, in addition to conventional statistical parameters,can be used to check the usability of an mtDNA DB. Finally, we tried to predictthe size of the whole mtDNA number in Korea using“ saturation concept”.

This paper examines how rural people understand, tolerate and respond to the COVID-19 socio-medical disaster as an affective event. Through an analysis of affect theory and the concept of affective-discursive practice, it explores how locals express affect tht cannot be observed or defined in the language in daily encounters with the local infection of COVID-19 without being easily grasped by the state, media, or capital. By focusing on the case of H local region, it demonstrates how the locals cross over rumors, memories, and emotions entangled with hatred and social atmosphere towards a person or group that has been suspected of spreading the virus and therefore breaking the ethical codes of the community. Through embodied practices of caring for the moral community as a shared common, it highlights how these local people become affective commoners. Moreover, it provides insights on the situational and relational dimensions of everyday politics as affective social, historical, material entanglements in local communities, suggesting a new study of affective politics in regional politics.

This article critically engages with and develops mapping methods in the study of dementia from an anthropological perspective. It shows how cartographic ethnography was acknowledged, appreciated, and improved upon in the process of obtaining ethical approval and conducting an ethnographic study in an Orthodox Jewish care home in London. Cartographic ethnography is an anthropological method of mapping that synthesizes Tim Ingold’s dwelling perspective and Ferdinand Deligny’s methods of co–living through the drawing of lines to document embodiment, movement, and multisensory experience. Here I take the example of Dorona, a resident of the care home who is living with dementia, to demonstrate that cartographic ethnography allows for a description and analysis of her contingent, relational, and creative attunement and correspondence in relation to her ever–changing worldly surroundings. I thus argue that cartographic ethnography is different from other mapping methods that mainly focus on visual representation and goes beyond the procedural descriptions of bodily expression and performative movements. Based on co–inhabiting and a sharing of day–to–day life with those affected, it allows the researcher to strongly reject any pathological and causal approaches to the study of dementia, and to carry out research in descriptive, collaborative, and dialogical ways. Such a mutually reciprocal and dementia friendly cartographic ethnography offers a platform where those affected, the researcher, and their respective biosocial surroundings can dwell together, in what I call an art of co–dwelling. Moreover, employing cartographic ethnography allows for those affected to be acknowledged and recognized not as objects of the research but as potential collaborators and co–producers in the making of co–dwelling. 본 논문은 지도법을 이용한 인지증(치매) 연구방법을 인류학 관점에서 비판적으로 발전시키고자 한다. 우선 영국 런던의 오소독스 유대인 요양원 연구의 연구윤리 승인 과정을 통해지도제작적 민족지의 가치를 어떻게 발견하게 되었는지를 서술한다. 지도제작적 민족지는팀 잉골드(Tim Ingold)의 주거 관점(dwelling perspective)과 함께 페르낭 들리니(Fernand Deligny) 의 공동생활과 체현, 움직임, 그리고 감각적 경험을 선을 통해 묘사·기록·분석한 연구방법을 결합하여 만든 인류학적인 지도 그리기라 할 수 있다. 본 논문에서는 특히 도로나(Dorona) 의 아침 식사 과정을 지도제작적 민족지를 통해 살펴봄으로써 그녀가 끊임없이 변화하는 삶의 조건과 상황들에 즉각적이며, 관계적이며, 창의적인 대응을 하고 있음을 밝힌다. 시각적재현에 중심을 둔 다른 지도법과는 달리 지도제작적 민족지는 표현적이며, 수행적인 몸의움직임에 대한 과정적 묘사에 그치지 않는다. 일상의 공간과 생활의 공유를 기본으로 병리학적·인과론적 접근을 지양하며, 묘사적이며, 협력적이며, 대화적이다. 이러한 상호호혜적이며, 인지증 친화적인 지도제작적 민족지는 인지증과 사는 사람을 포함한 그들 주위에 있는사람, 사물, 환경과의 공동 주거를 위한 하나의 기술(an art of co–dwelling)임을 보여준다. 나아가 인지증과 사는 사람들이 연구의 대상이 아니라 공동주거를 만들어가는 협력자이자 공동생산자임을 밝히는 과정이기도 하다.

After financial crisis at 1997, Korea pushed ahead with policy which attracting foreign direct investment (FDI). Therefore, FDI inflow to Korea was increased rapidly and influence of FDI on Korean economy was expanded. In this history, need of research which clearing effect of FDI on Korean economy was raised. Especially, it is so important that direct effect of FDI to Korean enterprises after financial crisis at 1997. According this idea, I developed research task. I analyze the performance of enterprises which attracted FDI with manufacturing industry data. To avoid the selection bias problem, I use Propensity Score Matching method. According the result of analysis, Korean enterprises had effects on capital formation, expanding production capacity and job creation. But there are no significant effects on productivity enhancement and prompting trade. This result is due to the purpose of FDI to Korea which securing production facility and market. 외환위기를 계기로 한국은 외국인직접투자(Foreign Direct Investment; FDI)를 적극적으로 유치하는 정책을 추진했다. 이로 인해 한국의 FDI 유입액이 크게 늘어나 경제전반에 미치는 영향력이 확대되었다. 이런 상황에서 FDI가 한국 경제에 미친 영향을규명하는 작업의 필요성이 대두되었다. 특히 외환위기 이후 이루어진 FDI가 한국 기업에 미친 직접적인 효과가 무엇인지 고찰할 필요가 있다. 방법론적으로는 선택편의(Selection bias) 문제를 해결하기 위해 성향지수매칭(Propensity score matching) 방법론을 사용하였으며, 제조업을 대상으로 분석을 수행하였다. 그 결과, 한국 기업은 FDI를통해 자본형성 및 생산역량 증대, 고용에 대한 효과를 얻은 것으로 나타났다. 그러나생산성 향상, 무역에 대해선 유의미한 효과를 관찰할 수 없었다. 이는 한국에서 이루어진 FDI의 목적이 생산시설 및 시장의 확보에 있고 기술이전이나 국제 네트워크 활용과는 거리가 있었기 때문으로 판단된다.

A next generation wireless system will be converged with a number of current wireless systems that have unique and individual features. These days, researches about the integration of a 3G cellular networks and NUN are fully activated. But they are not considered subject of the virtual home environment (VHE) and global roaming environment (GRE) which are defined for personal mobility in 3G wireless system. In the GRE and the VHE, there needs an authentication among different networks as well as between user equipment and access network. In this paper we deal with an extended authentication procedure which accepts the VHE and GRE of 3G wireless system regarding an integration of authentication between 3G cellular network and Wireless LAN.
