대한협회의 『대한민보』(1909~1910) 발간과 시사만화 연재의 성격

박지훈(Park, Ji-Hoon) 한국역사민속학회 2014 역사민속학 Vol.0 No.44

1909년 6월 2일 대한협회가 창간한 『대한민보』는 초대 사장 오세창의 주도아래 정통화가 출신인 이도영이 삽화라는 이름으로 시사만화를 연재하였다. 『대한민보』의 구성 중 삽화라는 이름의 시사만화를 구성하여 딱딱한 형식에서 벗어난 실험적인 구성으로 당대에 영향력 있는 신문으로 자리잡았다. 시사만화를 통해 계몽에 대한 의지를 적극적으로 표현하였고 특히 시각적 흥미를 유발하여 독자들이 신문을 접하도록 유도하였다. 이러한 시사만화는 독자를 끌어들이는 역할에 그치지 않고 시사만화의 시각적 효과를 통해 지나치기 쉬운 사건을 그림으로 표현하여 사회문제에 관심을 더 가질 수 있도록 유도하는 촉매제가 되었다. 그러나 이 시기의 시사만화는 한국 최초의 시사만화라는 점만 강조되고 기념될 뿐 연구적 가치로는 주목을 받지 못하고 있는 실정이다. 따라서 이 글에서는 『대한민보』시사만화의 주제와 작가의 의도를 정확히 파악하는 것을 목적으로 시작되었다. 『대한민보』의 시사만화는 크게 네 가지 유형으로 분류 할 수 있는데 첫 번째는 계몽을 요구하는 만화, 두 번째는 사회문제를 주제로 한 만화, 세 번째는 대한제국 정부와 열강들과의 문제들을 주제로 한 만화, 넷째는 친일 인사와 단체 그리고 언론을 비판한 만화이다. 이와 같은 분석을 통해 한일강제병합 직전의 사회상을 이해하고, 당시 대중들의 사회인식의 변화를 파악하려 한다. Daehan Association published the first edition of 『Daehanminbo』, a daily, on June 2nd, 1909. 『Daehanminbo』 became an influential journal as it added cartoon into typical newspaper forms. The efforts to enlighten people were strongly expressed through cartoon and these cartoon attracted people’s attention with visual factors. That is, cartoon led people to have more interests in social issues by expressing important events with pictures. Cartoon in 『Daehanminbo』 can be classified roughly into four types. The first type of cartoon aimed at enlightenment of the public. These types of cartoon were published in the early days of 『Daehanminbo』 and explained the purpose of Daehan Association properly. The second type dealt with social issues. 『Daehanminbo』 tried to let the public recognize reality by using cartoon that were familiar to people because of their sequence of drawings and words combined. The third type of cartoon mainly dealt with issues between the Daehan Empire and the powers. Gojong of the Korean Empire wanted to protect Korea against a Japanese invasion diplomatically, so he tried to weaken Japanese influence over Korea by dividing economic advantages and alienating them to Western powers. However, Gojong and the government of the Daehan Empire knew little of the international situation, so they were deprived of their economic rights by Japan. 『Daehanminbo』 put an effort into letting people know the Japanese invasion as well as social issues. The fourth type of cartoon criticized pro-Japanese Koreans, groups, and press. Pro-Japanese politicians and groups’ anti-national activities reached an extreme when Japanese annexation of Korea came to the finish. Their activities were good subjects for cartoon and 『Daehanminbo』 criticized those anti-national activities.

유리피판 및 자가골 이식을 이용한 복합 관골-상악결손 재건의 치험례

박지훈,장정우,최소영,김진수,권대근,Park, Ji-Hoon,Jang, Jung-Woo,Choi, So-Young,Kim, Chin-Soo,Kwon, Tae-Geon 대한악안면성형재건외과학회 2011 Maxillofacial Plastic Reconstructive Surgery Vol.33 No.1

Maxillary defects are inherently complex because they generally involve more than one midfacial component. In addition, most maxillary defects are composite in nature, and often require bony support, as well as a mucosal lining for reconstruction. Therefore, midfacial bone and soft tissue defects present a unique challenge because they require a complex arrangement of tissues in a relatively limited space. This might be difficult to achieve only with free osteocutaneous flaps. The use of bone grafts allows greater flexibility in a reconstruction but is limited by graft resorption. We report a case of a patient reconstructed with a lateral arm free flap, iliac bone graft, sagital split ramus osteotomy for the reconstruction of a right maxillary defect zygomatico-maxillary defect caused by a zygomatico-maxillary malignant tumor resection.

박지훈,이중서,이홍석,Park, Ji Hoon,Yi, Jung Seo,Lee, Hong Seock 대한불안의학회 2013 대한불안의학회지 Vol.9 No.2

Objectives : The aim of this study was to investigate clinical meaning of hallucination among patients with posttraumatic stress disorder (PTSD). Methods : PTSD patients with hallucination (n=50) were selected and matched with the PTSD patients without hallucination (n=50) by age and sex. The patients were evaluated in two different aspects, pathologic aspects which can develop after traumatic event, and positive/adaptive aspects which are concerned in positive psychology. In addition to these, temperament and character features between two groups were also evaluated using the Temperament and Character Inventory (TCI). Results : Except for the total score of DES (Dissociative Experience Scale) and the score of re-experience subscale of CAPS (Clinician Administered PTSD Scale), clinical characteristics did not show any significant difference between the two groups. Among the comparison of seven higher dimensions in TCI profiles, only Self-transcendence showed significant difference between the two groups. Conclusion : The two groups did not show significant differences in pathologic aspects except for factors that may contribute to development of hallucination. Furthermore, authors could not find any differences in positive/adaptive aspects.

합성곱 신경망의 Channel Attention 모듈 및 제한적인 각도 다양성 조건에서의 SAR 표적영상 식별로의 적용

박지훈,서승모,유지희,Park, Ji-Hoon,Seo, Seung-Mo,Yoo, Ji Hee 한국군사과학기술학회 2021 한국군사과학기술학회지 Vol.24 No.2

In the field of automatic target recognition(ATR) with synthetic aperture radar(SAR) imagery, it is usually impractical to obtain SAR target images covering a full range of aspect views. When the database consists of SAR target images with limited angular diversity, it can lead to performance degradation of the SAR-ATR system. To address this problem, this paper proposes a deep learning-based method where channel attention modules(CAMs) are inserted to a convolutional neural network(CNN). Motivated by the idea of the squeeze-and-excitation(SE) network, the CAM is considered to help improve recognition performance by selectively emphasizing discriminative features and suppressing ones with less information. After testing various CAM types included in the ResNet18-type base network, the SE CAM and its modified forms are applied to SAR target recognition using MSTAR dataset with different reduction ratios in order to validate recognition performance improvement under the limited angular diversity condition.

본 논문에서는 상용코드인 ANSYS CFX를 통한 해양레저 스포츠 및 야외 활동 시 사용 가능한 휴대용 수평축 수차의 유입유속(U) 및 주속비(TSR, Tip Speed Ratio) 변화에 따른 성능해석을 수행하였으며, 해석결과 및 유동장 분석을 통해 설계에 대한 검토 및 장치의 성능을 확인하였다. 또한, 추가적으로 블레이드의 피치각도(α_pitch) 변화에 따른 성능해석을 통해 수차의 성능개선에 필요한 데이터를 획득하고자 하였다. 본 논문의 연구 결과 수치해석 케이스 중 주속비 4인 경우, 모든 유입속도 및 블레이드 피치 각도에서 가장 높은 성능을 보였으며, 설계 유속 이하의 일부 조건에서도 설계 출력인 30 W 이상의 출력을 보였다. 그리고 수치해석 케이스 중 가장 높은 출력과 출력계수는 유입유속 1.5 m/s, 블레이드 피치 각도 3°, 주속비 4에서 보였으며, 출력 약 85 W, 출력계수 약 0.30이었다. A performance analysis was conducted according to changes in inflow velocity and the tip speed ratio of a portable horizontal-axis hydro turbine that can be used for marine leisure sports and outdoor activities by using the commercial computational fluid dynamics software ANSYS CFX. By using the analysis result and flow field analysis, the design was reviewed and the performance of the device was confirmed. In addition, data necessary to improve the performance of the hydro turbine were acquired by performing an additional performance analysis according to the variable blade pitch angle. The results among the numerical analysis cases show that the highest performance at all inflow velocities and blade pitch angles if achieved at a tip speed ratio of 4. The output power was found to be 30 W even under some conditions below the design flow rate. Among the numerical analysis cases, the highest output power (~ 85 W) and power coefficient (~ 0.30) were observed at an inlet flow rate of 1.5 m/s, a blade pitch angle of 3°, and a tip speed ratio of 4.

차원축소 없는 채널집중 네트워크를 이용한 SAR 변형표적 식별

박지훈,최여름,채대영,임호,Park, Ji-Hoon,Choi, Yeo-Reum,Chae, Dae-Young,Lim, Ho 한국군사과학기술학회 2022 한국군사과학기술학회지 Vol.25 No.3

In implementing a robust automatic target recognition(ATR) system with synthetic aperture radar(SAR) imagery, one of the most important issues is accurate classification of target variants, which are the same targets with different serial numbers, configurations and versions, etc. In this paper, a deep learning network with channel attention modules is proposed to cope with the recognition problem for target variants based on the previous research findings that the channel attention mechanism selectively emphasizes the useful features for target recognition. Different from other existing attention methods, this paper employs the channel attention modules without dimensionality reduction along the channel direction from which direct correspondence between feature map channels can be preserved and the features valuable for recognizing SAR target variants can be effectively derived. Experiments with the public benchmark dataset demonstrate that the proposed scheme is superior to the network with other existing channel attention modules.

DiffServ 방식의 Assured Service 에서 플로별 관리 없이 Fairness향상을 위한 Aggregate Fairness Marker

박지훈,허경,엄두섭,Park, Ji-Hoon,Hur, Kyeong,Eom, Doo-Seop 한국통신학회 2004 韓國通信學會論文誌 Vol.29 No.7B

본 논문은 DiffServ 방식에서 Assured Service를 이용하는 각 사용자 플로간에 수율의 공평성을 향상시키기 위하여 도메인 입구 라우터에서 Aggregate Fairness Marker (AFM)를 제안한다. 각 사용자별 플로의 패킷 표기 방법은 본 논문에서 제안하는 방법인 user flow Three Color Marker (uf-TCM)에 따라서 각각 green 패킷과 yellow 패킷, 그리고 red 패킷으로 구분되어 나온다. yellow 패킷은 uf-TCM에서 손실된 토큰을 소비하는 패킷 및 AFM에서 집합 트래픽에 대한 계약률을 준수하지 못하여 demotion 된 green 패킷에 대한 표기 방법이다. 제안하는 AFM은 플로별 관리 없이 공평한 방법으로 yellow 패킷을 green 패킷으로 promotion 하거나 green 패킷을 yellow 패킷으로 demotion 하여 사용자별 수율의 공평성 및 링크 이용률을 향상시킨다. DiffServ 내부 라우터에서는 yellow 패킷과 red패킷의 패킷 폐기 우선순위를 동일하게 하여 RIO 버퍼 관리 방식을 사용할 수 있게 한다. 성능 평가는 제안하는 AFM과 플로별 관리 없이 수율 공평성 향상을 위해 제안되었던 REDP Marker를 비교하였으며, 시뮬레이션 결과는 본 논문에서 제안하는 방식이 잉여 대역폭이 있는 경우와 최소대역폭이 있는 경우, 그리고 대역폭이 부족한 상황에서 각 사용자 플로간의 수율 공평성 및 링크 이용률 향상에 효과가 있음을 단일 도메인뿐만 아니라 다중 도메인 환경에서도 보인다. In this paper, we propose an Aggregate Fairness Maker (ARM) required for an Edge router to improve fairness of throughput among the flows of Assured Service in DiffServ with different round trip time (RTT) and we propose a user flow Three Color Marker (uf-TCM) as a flow marker that marks packets from the flow as green, yellow, or red. A yellow packet is the packet that consumes loss token in uf-TCM as well as that is demoted green packet in AM due to disobey the aggregate traffic profile. The proposed AFH promotes yellow packet to green packet or demotes green packet to yellow packet through the fair method without per-flow management, and it improves the feirness of throughput among the flows as well as link utilization. A yellow packet and a red packet have the same drop precedence at Core Router in our scheme. So we can use the RIO buffer management scheme. We evaluated the performance of our proposed AFM and the REDP Marker that was proposed to improve fairness without per-flow management. Simulation results show that, compared with the REDP marker, proposed AFM can improve performance of throughput fairness among the flows with different RTT and link utilization under the over-provisioning, exact-provisioning, and under-provisioning network environments at Multiple DiffServ domains as well as at Single DiffServ domain.

박지훈,김형진,오병훈,최건,정광윤,최종욱,Park, Ji-Hoon,Kim, Hyung-Jin,Oh, Byung-Hoon,Choi, Geon,Jung, Kwang-Yoon,Choi, Jong-Ouck 대한기관식도과학회 2000 大韓氣管食道科學會誌 Vol.6 No.1

Background : Stomal recurrence that occasionally follows total laryngectomy is associated with very poor prognosis regardless of treatment modality, so it is very important to identify high risk patients to prevent stomal recurrence. Objectives : We attempted to select an optimal management method to prevent stomal recurrence by analyzing risk factors in each patient who was found to have stomal recurrence following total laryngectomy. Materials and Methods : Risk factors in each of eleven patients who had stomal recurrence out of 159 patients who underwent total laryngectomy in the last ten years were analyzed retrospectively. Data were gathered on risk factors such as the presence of subglottic extension, extralaryngeal extension, thyroid gland invasion, lymph node metastasis, timing of tracheotomy, tumor stage, postoperative radiotherapy, and inclusion of the stoma in the radiotherapy field. Results : There were eight cases of subglottic extension, six cases of extralaryngeal invasion, one case of pharyngocutaneous fistula that occurred as a postoperative complication, and one case who was taken completion laryngectomy following conservation surgery. With the exception of one case who was taken tracheotomy prior to total laryngectomy, all tracheotomies were performed intra-operatively after endotracheal intubation. There was no evidence of paratracheal lymph node or prelaryngeal lymph node metastasis on preoperative neck CT scan. There were six cases of T4 tumors, four cases of T3 tumors, and one case of T2 tumor. Salvage surgery was performed following radiotherapy in three cases, and aside from one case who was not taken post-operative radiotherapy, postoperative radiotherapy including the stoma was performed in the remaining seven cases within one month after surgery. Conclusion : Total laryngectomy with wide paratracheal lymph node dissection, thyroidectomy, and tracheotomy should be performed for patients who have high risk factors such as subglottic extension and advanced stage. We believe that tracheotomy should be precede endotracheal intubation. Efforts should be made to prevent stomal recurrence by utilizing postoperative radiotherapy and by minimizing postoperative complications such as infection and fistula.
