일반적으로 가상 스피커 구현을 위한 음상정위 방법으로 HRTF(Head Related Transfer Function) DB를 원음에 convolution하는 기법을 사용하게 된다. 그러나 비개인화된 HRTF는 가상 스피커 구현에 있어 사용자에 따라 상/하 또는 앞/뒤 방향에 대해서 혼돈을 가져올 수 있어 정위감을 저하시킬 수 있다. 본 논문에서는 상/하, 앞/뒤 정위감을 개선하기 위해 가상 스피커 주변의 HRTF를 그룹화하여 만들어진 새로운 HRTF를 사용한 가상 스피커에 대하여 연구한다. 효과적인 HRTF 그룹화를 위해 필요한 HRTF 개수, 위치 등을 실험을 통해 결정하며, 청감 평가를 수행한다. 생성된 HRTF를 사용한 가상 스피커의 성능 평가 결과, 상/하, 앞/뒤 정위감이 개선됨을 실험을 통해 확인하였다.

For the last half-century, interprofessional education (IPE) has been identified and discussed as a critical educational process to facilitate collaboration in order to improve healthcare outcomes for healthcare participants. While the concept is not new, outcome-based research has provided few valid and reliable explanations of whether and how IPE can be effective in healthcare quality improvement. This challenge stems from the struggle to understand the epistemological meaning of IPE. The purpose of this literature review paper is to provide a synthesized understanding of IPE, its meaning, and to provide practical guidance for medical educators. The paper reviewed several key aspects of IPE. Professionalility was discussed to understand the historical background of IPE, followed by an explanation of the international trend of embracing the complexity of health care practice and the need for interprofessional collaboration. Additionally, several theoretical perspectives, such as general systems theory, social identity theory, and community of practice were reviewed to pinpoint what constitutes IPE. Several existing definitions were discussed with similar concepts (i.e., disciplinary vs. professional, and multi-, inter-, vs. trans-) to clarify the nature of knowledge and collaboration in IPE. Three concepts, including practice, authenticity of context, and socialization were proposed as key constructs of IPE, followed by appropriate timing of IPE, outcome research, directions for future research, and guidance for implementation. Community-based medical education practice, professional socialization within a community, and longitudinal system-based outcome research are recommended as future directions for research and practice.

Purpose: In our country, the aged population accounted for about 13% of the total population in 2018. In addition, it is expected to exceed 20% in 2026, entering an super-aged society. However, the senior welfare housing in Korea currently accommodates only 0.08% of the elderly population, and the increasing amount of the elderly population is very small. Accordingly, this study aims to analyze the causes of supply shortages and to propose directions for revitalizing the supply of welfare housing for the elderly in the private sector. Methods: First, the causes and problems of the poor supply of welfare housing for the elderly were analyzed. Next, the direction was proposed through institutional and case-by-case surveys and expert interviews. Results: It suggested directions such as legal and institutional improvement, inducing the use of REITs, preparing policies to support consumers, allocating a certain percentage of senior welfare housing for the elderly in the reconstruction project, improving awareness of monthly living expenses, and re-discussing sales permits. Implications: Experts said that the direction proposed in this study can have a positive effect on supply activation. However, there were many opinions that re-discussion on permission for sales was necessary due to the excessive impact of the inability to sell. In addition, further research is needed for specific application of the proposed direction.

Drought forecasting is crucial to minimize the damage to food security and water resources caused by drought. Satellite-based drought research has been conducted since 1980s, which includes drought monitoring, assessment, and prediction. Unlike numerous studies on drought monitoring and assessment for the past few decades, satellite-based drought forecasting has gained popularity in recent years. For successful drought forecasting, it is necessary to carefully identify the relationships between drought factors and drought conditions by drought type and lead time. This paper aims to provide an overview of recent research trends and challenges for satellite-based drought forecasts focusing on lead times. Based on the recent literature survey during the past decade, the satellite-based drought forecasting studies were divided into three groups by lead time (i.e., short-term, sub-seasonal, and seasonal) and reviewed with the characteristics of the predictors (i.e., drought factors) and predictands (i.e., drought indices). Then, three major challenges-difficulty in model generalization, model resolution and feature selection, and saturation of forecasting skill improvement-were discussed, which led to provide several future research directions of satellite-based drought forecasting.

시큐리티 종사자는 많은 고객의 욕구에 대한 전문적 지식을 갖고 있어야 하며, 갖고 있는 전문지식도 고객의 욕구에 따라 적절히 활용되어야 한다. 특히, 현대사회는 안전보호에 대한 욕구의 급상승에 따른 치안 수요가 급격히 증가되고, 또 고객이 요구하는 업무들도 다양해지고 있는 실정에서, 이제 시큐리티 종사자는 업무처리에 능동적으로 대처하는 자질과 능력이 요구된다고 하겠다. 이러한 관점에서 본 연구는 시큐리티 종사자의 조직학습과 조직성과간의 관계를 규명하는데 목적을 두고 있다. 첫째, 사회인구통계학적 특성에 따라 연구변수인 조직학습과 조직성과에 대한 구성원의 인식비율이 다르게 나타났다는 것을 알 수 있었다. 둘째, 시큐리티 종사자들의 조직학습과 조직성과와의 관계에서 조직학습수준이 높을수록 조직만족의 수준이 높은 것으로 나타났다. 셋째, 시큐리티 종사자들의 조직학습과 조직몰입의 관계에서도 조직에서의 조직학습문화의 수준이 높을수록 조직몰입의 수준이 높은 것으로 나타났다. 이러한 결과는 조직학습은 조직성과에 직접적인 영향을 미치고 있는 것으로 분석되었다. 본 연구의 결과를 바탕으로 시큐리티 종사자들의 조직학습과 조직성과의 제고를 위한 시큐리티 조직 발전과 쇄신이 필요하다.

Purpose: To evaluate the utility of implanted surgical clips for detecting interfractional errors in the treatment of hepatobiliary and pancreatic cancer with postoperative radiotherapy (PORT). Methods and Materials: Twenty patients had been treated with PORT for locally advanced hepatobiliary or pancreatic cancer, from November 2014 to April 2016. Patients underwent computed tomography simulation and were treated in expiratory breathing phase. During treatment, orthogonal kilovoltage (kV) imaging was taken twice a week, and isocenter shifts were made to match bony anatomy. The difference in position of clips between kV images and digitally reconstructed radiographs was determined. Clips were consist of 3 proximal clips (clip_p, ${\leq}2cm$) and 3 distal clips (clip_d, >2 cm), which were classified according to distance from treatment center. The interfractional displacements of clips were measured in the superior-inferior (SI), anterior-posterior (AP), and right-left (RL) directions. Results: The translocation of clip was well correlated with diaphragm movement in 90.4% (190/210) of all images. The clip position errors greater than 5 mm were observed in 26.0% in SI, 1.8% in AP, and 5.4% in RL directions, respectively. Moreover, the clip position errors greater than 10 mm were observed in 1.9% in SI, 0.2% in AP, and 0.2% in RL directions, despite respiratory control. Conclusion: Quantitative analysis of surgical clip displacement reflect respiratory motion, setup errors and postoperative change of intraabdominal organ position. Furthermore, position of clips is distinguished easily in verification images. The identification of the surgical clip position may lead to a significant improvement in the accuracy of upper abdominal radiation therapy.

This study is aimed at finding policy directions for Korean fisheries and fishing villages by using Delphi method for fisheries experts. Fisheries experts have highly evaluated the achievements of fostering aquaculture industry, seafood export support measures, and natural disasters relief and recovery arrangements among the policies promoted as so far. And it was recognized that policies such as fishery resources management, creation and recovery of fishery resources, improvement hygiene and seafood safety, and provision young fishermen with training and capacity building will be important. Future megatrends, for example changes in food consumption pattern, climate change, and demographic structure changes are expected to have a significant impact on fisheries and fishing villages. The Delphi survey indicates that the most important policy objective is to secure a stable fisheries production. In other words, fisheries policy in the future should be aimed at suppling sustainable seafood for popular consumption. Finding strategies and action plans that can achieve this goal will be an important policy issue. In conclusion, it is necessary that a number of fundamental researches carry out in Korea, which can lead to finding out a multifunctionality of fisheries and fishing village. In addition, it is important to expand the scope of fisheries policy, which can consider not only the fisheries producers but also seafood consumer's and young fishermen perspectives. Furthermore, it recommends that fishery policy needs to include fishery related industry as well as application of 4th industrial revolution technology to fishery.
