The reconstruction of the suborbital area followed by resection of skin cancer has been used many methods including skin graft, local flaps, free flaps, and skin expansion. The radial forearm free flap has become a workhorse flap in this area because of its lack of bulk, ease of dissection, malleability, and hairlessness. When the suborbital defect especially including full-thickness defect of lower lid was reconstructed with many free flaps, the ectropion and the deformity of medial and lateral canthal area were common problems encountered as late complication due to gravitational descent. To improve the final aesthetic result in patients with suborbital defect, the radial forearm free flap was elevated as a composite radial forearm - palmaris longus free flap, in which the vascularized palmaris longus london was included and anchored to the periorbital bone with $mitek^{(R)}$ as sling, to suspend the flap against gravity and inferior descent, and thereby creating a more natural cheek contour. Two clinical cases were presented as an example of this procedure. Postoperative results emphasize the importance of suspension sling with palmaris longus tendon using $mitek^{(R)}$ in reconstruction of the suborbital defect with radial forearm free flap.

This study deals with the degree of enclosure on the Court Space in 'Suh-Won' that has warious perceptual composition elements. 1. The size of Court Space in which we can read the complexion of others and easily understand every behavior of them is similar to that of the 'Madang' in the Korean traditional houses. 2. The angles of elevation are within the range of suitable enclosure as going from the center of the court Space to 'Kang-Dang' and the space -from the center of the Court Space to 'Kang-Dang'- is restricted and surrounded. It is also within the range of the least enclosure as going from the center of the Court Space to the 'Mun-Ru'. 3. The degrees of enclosure based on the horizontal angle are within the degree we can perceive the objects of structure easily. 4. The degree of enclosure based on the ratio D/H is increased as approaching from 'Mun-Ru' to 'Kang-Dang'. The distance as approaching from 'Mun-Ru' to 'Kang-Dang' is changed from social distance to personal distance. To conclude this the Court Space in 'Suh-Won' represents the hierarchical system with variety and the degree of enclosure and the size of space are within the range of human scale.

Fabrication of Micro/Nanostructures is come into the spotlight because of its potential at healthcare, electronic device and military related applications. However, existing fabrication processes contains limits in terms of rapid prototyping, due to its complicate manufacturing process, difficulties in achieving complex structure and limit of available materials. Herein, we developed novel nanoscale 3D printing system by integrating nanoparticle deposition system and focused ion beam.
Regulation of “Environmentally Harmful Subsidies” in the WTO

어자원 고갈로 인해 세계 어업이 심각한 위기에 처해있다. 어자원 고갈의 직접적인 원인은 과도능력 (overcapacity)과 남획(overfishing)이라고 할 수 있겠는데, 과도능력과 남획을 부추기는 것은 세계 각국 정부가 자국 어업에 지급하는 보조금이다. 따라서, 지속가능한 어자원의 활용을 위해 이러한 어업보조금 규제가 절실하다고 하겠으나, 현 WTO 보조금 협정의 규정으로는 어업보조금을 규제하기 어려운 실정이다. 그 이유는, WTO 보조금 협정이, 보조금의 무역왜곡 효과를 막기 위한 목적으로 체결되어, 그 구체적인 규정들을 어업보조금에 적용하기는 어렵기 때문이다. 즉, 어업보조금으로 인한 어자원의 고갈 및 환경적 피해를 보조금 협정 하의 수출보조금 금지규정이나 조치가능 보조금 규정으로 다룰 수 없는 것이다. WTO 회원국들도 이러한 사실을 인식하고, 어업보조금에 대한 WTO 규제를 명확히하고 개선하기 위한 목적으로 협상을 개시하였으며, 아직 확정적인 결과를 내놓지는 못하였지만, 많은 부분에 있어서 논의의 진전이 있었으며, 이는 Chair’s Text에 상당부분 나타나 있다. 어업보조금은 소위 “환경적으로 유해한 보조금”의 대표적인 예로 볼 수 있는데, 어업보조금 규제에 대한 WTO 회원국들 간의 논의 과정은 미래의 다른 “환경적으로 유해한 보조금” 규제에 있어서 많은 시사점을 던져주고 있다. 예를 들어, 조치가능 보조금 개념의 부적합성, S&D 조항의 필요성, 통상-환경 간의 협력의 중요성 등이 그것이다. The magnitude of global fisheries crisis is staggering. According to the UNEP report, 80% of commercially valuable fish stocks are now at various stages of depletion. It is generally agreed that the cause of global fisheries crisis is “overcapacity” and “overfishing” and that the fisheries subsidiesis the main cause of such overcapacity and overfishing. However, the current ASCM proved to be inadequate to regulate fisheries subsidies because the objective of the ASCM is to counter the trade-distorting effects of the subsidy, not those kinds of harm that fisheries subsidies normally bring about, i.e. environmental harm. As a result, fisheries subsidies do not fit into the language and the structure of the ASCM. WTO Members have recognized this problem, and in Doha, they agreed to launch negotiations with the aim to “clarify and improve WTO disciplines on fisheries subsidies taking into account the importance of this sector to developing countries.” Fisheries subsidy is a good example of so called “environmentally harmful subsidies” and discussions on fisheries subsidies offer us an useful lessons and insights for future regulation of other environmentally harmful subsidies, namely, inadequacy of actionable subsidy concept and the importance of regime interaction.

Background: Quality and quantity of Cheongung (Cnidium officinale Makinoi) is reduced by plant viral infections. Therefore, it is necessary to develop effective detection methods for diagnosis of problematic viruses in Cheongung farms. This study aimed to develop lateral flow reverse transcription recombinase polymerase amplification (LF-RT-RPA) assay for the detection of cucumber mosaic virus (CMV) in C. officinale. Methods and Results: Total RNA was extracted from CMV-infected Cheongung plant and subjected to RT-RPA reaction with RPA_CMV-CP-F1/R1 primers targeting the CMV RNA3 sequence. When specificity was examined using lateral flow Immunostrip, experimental and control lines were generated only in the sample from the CMV-infected plant, while control lines were observed in samples from cnidium vein yellowing virus-1, cnidium vein yellowing virus-2, and apple stem grooving virus-infected Cheongung plants. The optimal temperature and reaction time for LF-RT-RPA assay were determined to be 37℃ and 15 min. On-site diagnosis carried out to detect CMV in 7 Cheongung plants showing viral-infection symptoms, confirmed six of the plants infected with CMV. Conclusion: CMV, one of the prevalent plant viruses, was effectively detected using LF-RT-RPA assay without the need of any equipment on farms. Detection limit for CMV in C. officinale Makinoi was up to 100 fg of total RNA, suggesting that the LF-RT-RPA assay developed in this study is suitable for on-site detection of CMV in Cheongung farms.
