장우석,호요성,Jang, Woo-Seok,Ho, Yo-Sung 한국스마트미디어학회 2012 스마트미디어저널 Vol.1 No.3

깊이 정보의 획득은 다양한 3차원 콘텐츠 제작을 위해서 필수적이다. 깊이 획득은 깊이 정보를 어떻게 획득하느냐에 따라서 크게 두 가지 방식(능동적, 수동적 깊이 센서 방식)으로 나뉜다. 본 논문에서는 몇 가지 측면에서 깊이 정보를 획득하는 방법을 살펴보고, 이들 방식을 통해 깊이를 획득하는 방법뿐 아니라, 각 방식의 약점을 보완하기 위해 두 가지 접근 방법을 혼합하여 깊이 정보를 획득하는 방법도 제시한다. 또한 3차원 비디오에서 매 화면마다 독립적으로 깊이 정보를 추정하여 생기는 깜빡거림 현상과 시각적 피로도를 줄이기 위해서 시간적 상관도를 고려하여 정합 에너지 함수를 정의하는 방법과 후처리하는 방법도 제시한다. Depth information is necessary for various three dimensional contents generation. Depth acquisition techniques can be categorized broadly into two approaches: active, passive depth sensors depending on how to obtain depth information. In this paper, we take a look at several ways of depth acquirement. We present not only depth acquisition methods using discussed ways, but also hybrid methods which combine both approaches to compensate for drawbacks of each approach. Furthermore, we introduce several matching cost functions and post-processing techniques to enhance the temporal consistency and reduce flickering artifacts and discomforts of users caused by inaccurate depth estimation in 3D video.

This study was to evaluate a case of foot drop treated with placenta pharmacopuncure. After thirteen times of treatment, I evaluated this case by the angle of dorsiflexion, the total sum of gaiting points, the time of heel standing. As a result of evaluation, the angle of dorsiflexion, total sum of gaiting points, time of heel standing were improved. The placenta pharmacopuncture can be used for foot drop and other peripheral nerve palsy.

Background: The present study aimed to investigate the immediate effects of Soft Tissue Mobilization (STM) before Mobilization with Movement (MWM) on ankle ROM, pennation angle, balance in stroke patients. Methods: A total of 22 subjects were randomly assigned to one of two groups: the experimental group and the control group. The experimental group received intervention STM before MWM. STM was applied for one minute, MWM was applied one set of six times, in a total 3 sets. The passive ankle joint range of motion (ROM) was measured using a goniometer, the pennation angle was measured using RUSI, and the balance was measured using Timed Up & Go Test. Results: The ROM of the ankle dorsi-flexion, muscle tissue (pennation angle) and balance were significantly increased. Conclusion: In this study, it was confirmed that the ankle dorsi-flexion ROM, pennation angle of the medial gastrocnemius muscle, and balance were significantly improved in the group where STM was performed before the MWM intervention. Therefore, the physiotherapists should consider these results in their intervention. If MWM is applied to stroke patients, applying STM first is a better intervention.

Constipation is a common symptom, but stroke patients are especially susceptible to constipation due to colon ineutia as a result of prolonged bed rest. In these two cases, patients diagnosed as Gieumliangheu had bowel complaints and defecated a small quantity of loose form. Therefore the patients were treated with Boemyikgijeon. Patients showed improvement in this symptom, so Boemyikgijeon is cited for the better treatment.

Objective: This study was designed to analyze the fatigability of workers in the automobile company by Heart Rate Variability (HRV), Method: The subjects consisted of 32,049 workers who had answered about questionnaires of a job position, age, the state of drinking, smoking, exercise and sex, The fatigability was examined by SA3000P, We analyzed the differences of fatigability according to job positions, ages, the state of smoking, drinking, exercise and sex by T-test or ANOVA with SPSS ver17.0, Results Regarding the differences of fatigability among job classes, the fatigability was highest in engineers, lowest in others. Among ages, the fatigability was highest in 20s, lowest in 50s. In smoking, the fatigability was higher in smoking group. In drinking, the fatigability was higher in drinking group. In exercise, the fatigability was higher in non-exercising group. In sex, there was no significant difference. Conclusion: According to these results, we should establish the methods of controlling fatigue from the perspective of Korean traditional medicine.

온라인 의견을 통한 대한민국 공군의 이미지 분석 : 감성 분석 접근

장우석 ( Jang Woo Seok ) 공군사관학교 2017 空士論文集 Vol.68 No.1

안보 위협이 급증하면서, 대한민국 공군은 국가 방위 임무를 수행하기 위해 공군의 위상을 국민에게 알려왔다. 이 과정에서 공군의 이미지를 높이기 위해, 국민의 의견에 대한 빠른 피드백의 필요성이 대두되고 있다. 과거 연구는 피드백을 위해 설문조사를 활용하였지만, 이는 국민의 의견보다 전문가 의견에 강한 영향을 받는다. 블로그나 SNS(Social Network Service) 내 온라인 의견은 국민의 생각을 온전히 담고 있으며, 광고보다 파급력이 크다는 점에서 가장 좋은 피드백 수단이 될 수 있다. 이에 본 연구는 공군과 관련하여 국민이 남긴 온라인 의견을 분석하여 국민이 1) 어떤 대상에 대해 2) 어떻게 생각하는지 확인하였다. 텍스트마이닝 기법을 활용하여 추출한 핵심 단어를 분석하여 국민이 공군의 어떤 대상이나 특성에 대해 이미지를 가졌는지 파악하였다. 또한, 온라인 의견이 긍정적으로 작성되었는지 파악하기 위해 감성 분석을 활용하였다. 본 연구는 국민이 직접 작성한 온라인 의견을 활용했다는 점에서 진솔하고 국민의 생각과 일치하는 자료로 군 조직 이미지를 분석했다는 의의가 있다. With increasing the threat of national security, ROKAF(Republic of Korea Air Force) has been informing the status of them for people, which it is a must in national defense. To raise the image of ROKAF, the importance of feedback for people is steadily increasing. Many previous studies have carried out survey to get feedback from the public, survey are likely to be created by experts' opinions more than by the public. So, various online opinions from blog and SNS can be best alternative data to get the feedback related the image of ROKAF. Because these data can reflect the writer's opinion through frank sentences, and tend to more influence other people than advertisement. This study identifies 1) what features(objects) are frequently mentioned and 2) how to evaluate these features in online opinion, by analyzing the posts from blog and SNS. To do this, we extract the keyword to identify the frequently mentioned features. And we conduct the sentiment analysis to analyze the polarity of each online opinion. Major contribution of this study is trial to use online opinion which in concordance with the people's idea, thus, this framework is expected to meet with good feedback from people.

실감형 화상 회의를 위해 깊이정보 혼합을 사용한 시선 맞춤 시스템

장우석(Woo-Seok Jang),이미숙(Mi Suk Lee),호요성(Yo-Sung Ho) 대한전자공학회 2015 전자공학회논문지 Vol.52 No.7

본 논문에서는 실감형 원격 영상회의를 위한 시스템을 제안한다. 원격 영상회의에서 카메라는 보통 디스플레이의 중앙이 아닌 측면에 설치가 된다. 이는 시선 불일치를 만들고, 사용자들의 몰입도를 떨어뜨린다. 따라서 실감형 영상회의에 있어서 시선맞춤은 중요한 부분을 차지한다. 제안하는 방법은 스테레오 카메라와 깊이 카메라를 사용하여 시선 맞춤을 시도한다. 깊이 카메라는 비교적 적은 비용으로 효율적으로 깊이 정보를 생성할 수 있는 키넥트 카메라를 선택하였다. 하지만 키넥트 카메라는 비용적인 장점에도 불구하고 단독으로 사용하기에는 내제하는 단점이 많다. 따라서 스테레오 카메라를 더하여 각 깊이 센서간의 단점을 보완하는 방법을 개발하였고, 이는 각 깊이 정보 간의 혼합 및 정제 과정을 통해서 실현된다. 시선 맞춤 영상 생성은 후처리를 통한 보완된 깊이 정보를 이용하여 3차원 워핑 기술을 이용하여 구현된다. 실험결과를 보면 제안한 시스템이 자연스러운 시선 맞춤 영상을 제공하는 것을 알 수 있다. In this paper, we propose a gaze correction method for realistic video teleconferencing. Typically, cameras used in teleconferencing are installed at the side of the display monitor, but not in the center of the monitor. This system makes it too difficult for users to contact each eyes. Therefore, eys contact is the most important in the immersive videoconferencing. In the proposed method, we use the stereo camera and the depth camera to correct the eye contact. The depth camera is the kinect camera, which is the relatively cheap price, and estimate the depth information efficiently. However, the kinect camera has some inherent disadvantages. Therefore, we fuse the kinect camera with stereo camera to compensate the disadvantages of the kinect camera. Consecutively, for the gaze-corrected image, view synthesis is performed by 3D warping according to the depth information. Experimental results verify that the proposed system is effective in generating natural gaze-corrected images.
