        박근혜 정부의 외교안보정책 구상과 한일관계

        박영준(Young-June Park) 고려대학교 일민국제관계연구원 2013 국제관계연구 Vol.18 No.2

        박근혜 정부는 “한반도 신뢰프로세스”와 “동북아 평화협력구상”을 외교안보정책의 주요 키워드로 제시하면서 출범하였다. 이 구상은 이전의 김대중, 노무현, 이명박 정부에서 표방되었던 대북정책 및 지역질서 구상과 연속성을 갖는다. 다만 박근혜 정부의 정책구상은, 북한의 핵폐기나 역사문제에 대한 일본의 성의있는 태도 변화 등 타자의 정책변화를 전제조건으로 하는 것이어서, 한국이 수행해야 할 주도적 역할에 대한 성찰이 부족하다는 한계를 갖고 있는 것으로 보인다. 이러한 한계에 더해 아베 자민당 정부의 수정주의적 보통국가화 경향으로 인해 한일관계는 최악의 상황을 맞고 있다. 일본은 한반도 신뢰프로세스나 동북아 평화협력을 위해, 우리가 활용할 여지가 많은 상대국가이다. 박근혜 정부의 대외정책 성공을 위해서도 내셔널리즘을 극복한 전략적 대일외교정책이 필요하다. The Park Geun-hye administration proposed ‘the idea of the East Asian peace and cooperation’ as well as ‘trustpolitik on the Korean peninsula’ as its foreign policy agendas. Despite a slight change of its wording, these policies succeeds her predecessors’ policies toward North Korea and the Northeast Asian region. However, President Park Geunhye’s policies seemed to lack self-propelled initiatives which will enable neighboring countries to join a road to mutual trust and cooperation. Instead the Park administration has just asked Pyongyang for denuclearization and Tokyo for a change of attitude toward an issue of past history. In addition to Park’s passive foreign policy agendas, Prime Minister Shinjo Abe’s right-wing policies have worsened the Korea-Japan relations furthermore. Considering its potential in terms of security and economics, Japan should be considered as an important partner for the implementation of President Park’s trustpolitik as well as the idea of peace and cooperation in the Eat Asia. For the success of President Park’s foreign policy agendas, Korea-Japan relations should be re-set on a normal track overcoming the nationalistic sentiment.

      • 디스플레이 현황과 발전방향 -실감 및 스킨 기기로의 확대

        박영준,Park, Y.J. 한국전자통신연구원 2019 전자통신동향분석 Vol.34 No.2

        Since the introduction of CRT(Cathode Ray Tube) in the 1950s, display technologies have been developed continuously. Flat panel displays such as PDP(Plasma Display Panel) and LCD(Liquid Crystal Display) were commercialized in the late 1990s, and OLED(Organic Light Emitting Diodes) and Micro-LED(Micro-Light Emitting Diodes) are now being developed and are becoming widespread. In the future, we expect to develop ultra-realistic, flexible, embedded sensor displays. Ultra-realistic display can be applied to AR/VR(Augmented Reality/Virtual Reality) devices and spatial light modulators for holography. The sensor-embedded display can be applied to robots; electronic skin; and security devices, including iris recognition sensors, fingerprint recognition sensors, and tactile sensors. AR/VR technology must be developed to meet technical requirements such as viewing angle, resolution, and refresh rate. Holography requires optical modulation technology that can significantly improve resolution, viewing angle, and modulation method to enable wide-view and high-quality hologram stereoscopic images. For electronic skin, stable mass production technology, large-area arrays, and system integration technologies should be developed.

        가토의 두개골에서 티타늄 반구를 이용한 다양한 onlay bone graft시 골형성 능력

        박영준,최근호,장정록,정승곤,한만승,유민기,국민석,박홍주,유선열,오희균,Park, Young-Jun,Choi, Guen-Ho,Jang, Jung-Rok,Jung, Seung-Gon,Han, Man-Seung,Yu, Min-Gi,Kook, Min-Suk,Park, Hong-Ju,Ryu, Sun-Youl,Oh, Hee-Kyun 대한악안면성형재건외과학회 2009 Maxillofacial Plastic Reconstructive Surgery Vol.31 No.6

        육안적 검사결과 실험군과 대조군 모두에서 특별한 염증 소견이나 창상 이개 없이 반원 모양의 골형성이 관찰되었다. 조직학적으로 3주째에 대조군, 실험 1군, 실험2군, 실험 3군 모두 이식골 주위 및 티타늄 반구 내면을 따라 신생 골형성이 관찰되었다. 조직학적으로 6주째에 모든 군에서 3주째에 비하여 신생골 면적의 증가 및 성숙 소견이 관찰되었고, 실험2군에서는 부분적으로 이식골이 흡수되면서 신생골이 형성되는 것이 관찰된 반면, 실험 3군에서는 이식골의 흡수 소견이 관찰되지 않았다. 조직형태계측학적으로 3주, 6주 모두 자가골에서 가장 많은 신생골 형성이 나타났고, 신생골 면적 비교시 자가골, 이종골, 합성골 순으로 크게 나타났고, 각 군간의 통계학적으로 유의한 차이는 없었다(p>0.05). 본 연구결과 골유도 재생술시 골형성 능력은 자가골이 가장 좋지만, 자가골 채취가 불가능할 경우, 적절한 차폐막을 사용한 합성골과 이종골 복합 이식방식도 좋은 대체제가 될 것으로 생각된다. Purpose: This study was performed to evaluate the effect of various graft materials used with a titanium cap on the ability of new bone formation in the rabbit calvarium. Materials and Methods: A total of 32 sites of artificial bony defects were prepared on the calvaria of sixteen rabbits by using a trephine bur 8 mm in diameter. Each rabbit had two defect sites. 0.2 mm deep grooves were formed on the calvaria of sixteen rabbits by using a trephine bur 8 mm in diameter for the fixation of a titanium cap. The treatments were performed respectively as follows: without any graft for the control group (n=8), autogenous iliac bone graft for experimental group 1 (n=8), alloplastic bone graft ($SynthoGraft^{(R)}$, USA) for experimental group 2 (n=8), and xenogenic bone graft ($NuOss^{(R)}$, USA) for experimental group 3 (n=8). After the treatments, a titanium cap (8 mm in diameter, 4 mm high, and 0.2 mm thick) was fixed into the groove. At the third and sixth postoperative weeks, rabbits in each group were sacrificed for histological analysis. Results: 1. In gross examination, the surgical sites showed no signs of inflammation or wound dehiscence, and semicircular-shaped bone remodeling was shown both in the experimental and control groups. 2. In histological analysis, the control group at the third week showed bone remodeling along the inner surface of the cap and at the contact region of the calvarium without any specific infiltration of inflammation tissue. Also, there was no soft tissue infiltration. Bone remodeling was observed around the grafted bone and along the inner surface of the titanium cap in experimental group 1, 2, and 3. 3. Histologically, all groups at the sixth week showed the increased area of bone remodeling and maturation compared to those at the third week. In experimental group 2, the grafted bone was partially absorbed by multi nucleated giant cells and new bone was formed by osteoblasts. In group 3, however, resorption of the grafted bone was not observed. 4. Autogenous bone at the third and sixth week showed the most powerful ability of new bone formation. The size of newly formed bone was in decreasing order by autogenous, alloplastic, and heterogenous bone graft. There was no statistically significant difference among autogenous, alloplastic, and heterogenous bones(p>0.05). Summary: This result suggests that autogenous bone is the best choice for new bone formation, but when autogenous bone graft is in limited availability, alloplastic and xenogenic bone graft also can be an alternative bone graft material to use with a suitably guided membrane.

        접적지역 대피소 방호수준 설정에 관한 연구

        박영준,박상진,엄홍섭,손기영,Park, Young Jun,Park, Sangjin,Eom, Hong Seob,Son, Kiyoung 한국군사과학기술학회 2015 한국군사과학기술학회지 Vol.18 No.4

        Protection against direct projectiles has been adapted just to the main command posts in the existing protective facility standards. However, protective capacity for the shelters against direct projectiles is also required because the initial survivability as well as the operation sustainment of the shelters is critical during a couple of days from outbreak of war. In this study, the Russian artillery is used to determine the existing and future threat of the North Korean Armed Forces indirectly. And then, required protective capacity of military shelters in the contact areas is calculated along with UFC 3-340-02 and it is verified using modeling and simulation. Based on the assessed capacity, actual inspect of military facilities with contact areas on spot is performed whether military shelters have enough protection capacity against determined threats. According to the field study, it is verified that proper earth bermed shelter has enough protection capacity. The results in this study could be used how to retrofit the current shelters in the contact areas.
