Background A high incidence of breast animation deformity (BAD) has been reported following immediate breast reconstruction with subpectorally placed implants. The aim of this study was to assess and compare the incidence of BAD in women who underwent either subpectoral or prepectoral immediate breast reconstruction. Therefore, we developed a grading tool and tested its reproducibility in a clinical setting. Methods Video recordings of 37 women who had undergone unilateral or bilateral immediate breast reconstruction were evaluated by two consultant plastic surgeons. The degree of BAD was assessed by our grading tool, named the Nipple, Surrounding Skin, Entire Breast (NSE) grading scale, which evaluates the degree of tissue distortion in three areas of the breast. Blinded assessments were performed twice by each observer. Results Eighteen patients were reconstructed with subpectoral implant placement and 19 with prepectoral implant placement. Using the NSE grading scale, we found a significant difference in the degree of BAD between the groups, in favor of patients who underwent prepectoral immediate breast reconstruction (0.2 vs. 4, P=0.000). Inter- and intraobserver agreement was moderate (74%) to strong (88%). Conclusions The incidence and severity of BAD was significantly lower in women reconstructed with a prepectorally placed implant than in those who underwent subpectoral immediate breast reconstruction. All patients reconstructed using the subpectoral technique had some degree of BAD. The inter- and intraobserver agreements were high when using the NSE grading scale, suggesting it is an easy-to-use, reproducible scale for assessing BAD in women who undergo immediate breast reconstruction.

Korea and China are neighboring countries with close contacts in many areas from long time ago, and have shared interests in maintaining peace and stability on the Korean Peninsula, and in deepening economic relationship which has been mutually complementary in their nature. Therefore their bilateral relations has been developed at a remarkable pace to the extent that it can't be better than now. However, the differences in their responses to North Korean nuclear test and ensuing long-range ballistic missile test-fire and the Chinese strong concern on the possible deployment of THAAD (Terminal High Altitude Air Defence) anti-missile system in Korea show that there are some weaknesses in their relations. For example, Korea is not still confident that China would fully implement the sanction measures contained in the UNSC resolution and I argue that Chinese proposal of parallel negotiation of the denuclearization and the replacement of Korean armistice with the Peace Agreement is not much persuasive. In THAAD issue, if Korea comes to conclusion in the future that THAAD is the most effective way to counter North Korean threats, Korea should make every efforts to assure China that Korea-US alliance is not targeting China, and the THAAD is a defensive system, not damaging Chinese security. In the longer-term, deepening strategic distrust and competition between the US and China in this part of East Asia, changing nature of economic cooperation between Korea and China, and the revival of 'great country mentality' by Chinese people together with the rising nationalism in both Korea and China would cast shadow on Korea-China relation in the years ahead, unless properly handled. In this regard, I suggest that the security communications between the two countries be further strengthened, and the tri-lateral dialogue channel be established among the three countries of Korea, the US and China, particularly on North Korean issues. I also suggest the new pattern of economic cooperation be sought, considering the changing economic environment in China, while strengthening the efforts to understand each other through more interactions between the two peoples.

국제자유무역주의가 지속적으로 확대됨에 따라 국가 간의 항공협정에서 민감한 문제로 제한하고 있던 운항에 관한 제반 조건을 항공사가 시장상황에 따라 자유롭게 결정할 수 있도록 하는 항공자유화(Open Skies policy)정책이 세계적으로 확산되고 있다. 범세계적으로 이해당사국간, 다자간 협정방식으로 항공자유화가 추진되고 중국항공시장에도 도입됨에 따라 항공사간 무한 경쟁이 예고되며 항공사의 경쟁력, 국제공항의 허브화, 항공수요의 변화가 주목되고 있다. 최근 중국은 대외무역의 급격한 성장과 함께 세계 제2위의 항공시장으로 성장하였다. 또한 다른 나라들과의 양자간 항공자유화 협정이 체결됨에 따라 중국의 항공시장구조와 항공사의 시장지배력에 큰 영향을 미치고 있다. 따라서 중국항공시장을 이해하기 위해서는 중국의 항공자유화정책과 항공운송시장의 특징에 대한 분석이 필요하다. 본 논문은 먼저 중국의 민간항공산업에 있어서 정부와 시장의 역할에 초점을 두고 중국의 항공자유화정책의 진척상황을 조망하였다. 둘째로 시장규모, 경쟁구조, 시장집중도 및 진입장벽 등 4개 측면에서 중국항공산업구조를 분석하였다. 본 논문에서 이용한 허핀달-허쉬만지수를 통한 실증분석 결과, 중국의 항공시장은 과점시장구조를 보이고 있는 것으로 나타났다. 끝으로 중국항공운송시장에 참여하는 항공사는 항공동맹체 가입을 적극적으로 모색하거나 여타 항공사와는 차별화된 상용고객우대프로그램(FFP) 개발 등 경쟁력 강화를 위한 조치가 필요하다는 정책적 시사점을 도출하였다.

Leaving the legacies of the Cold War and other difficulties behind them, South Korea and China are building up their successful strategic cooperative partnership, moving forward toward through the development of new economic exchanges and diplomatic cooperation between the two countries, and this process is expected to gain momentum during 2015. 2015 is the third year since President Park of South Korea and President Xi of China came into office, and also the first year they have begun to implement the many declarations and promises which they have made within the context of the strategic cooperative partnership. The two nations share a common cultural heritage, and their governments should take this opportunity to leverage their partnership to enhance their economies and to improve their people's quality of life, especially for the younger generation. At a summit held in July 2014, the two leaders agreed to launch a working-level group on maritime boundary delimitation. The first meeting took place on January 29, 2015, and addressed issues of Exclusive Economic Zones (EEZs) and continental shelves in the Yellow Sea, which has an area of about 380,000 ㎢. It is greatly to be hoped that the 2015 maritime boundary delimitation meeting between South Korea and China will not impair the future of bilateral relations, but rather will improve their prospects. South Korea and China must take the opportunity to secure a definitive delimitation of their maritime boundary; their strategic cooperative partnership is in good order and China is currently taking a somewhat more flexible stance on the ECS and the SCS, so an agreement on boundaries will serve as a useful model for regional maritime cooperation.

The Three Mile Island Unit 2 (TMI-2) accident has been studied extensively, as part of both post-accident technical assessment and follow-up computer code calculations. The models used in computer codes for severe accidents have improved significantly over the years due to better understanding. It was decided to reanalyze the severe accident scenario using current state of the art codes and methodologies. This reanalysis was adopted as a part of the joint standard problem exercise for the Atomic Energy Regulatory Board (AERB) - United States Regulatory Commission (USNRC) bilateral safety meet. The accident scenario was divided into four phases for analysis viz., Phase 1 covers from the accident initiation to the shutdown of the last Reactor Coolant Pumps (RCPs) (0 to 100 min), Phase 2 covers initial fuel heat up and core degradation (100 to 174 min), Phase 3 is the period of recovery of the core water level by operating the reactor coolant pump, and the core reheat that followed (174 to 200 min) and Phase 4 covers refilling of the core by high pressure injection (200 to 300 min). The base case analysis was carried out for all four phases. The majority of the predicted parameters are in good agreement with the observed data. However, some parameters have significant deviations compared to the observed data. These discrepancies have arisen from uncertainties in boundary conditions, such as makeup flow, flow during the RCP 2B transient (Phase 3), models used in the code, the adopted nodalisation schemes, etc. In view of this, uncertainty and sensitivity analyses are carried out using simulation based techniques. The paper deals with uncertainty and sensitivity analyses carried out for the first three phases of the accident scenario.

The purpose of this article is to examine Fair and Equitable Treatment in International Investment Agreements. Most BITs and other investment treaties provide for FET of foreign investments. Today, this concept is the most frequently invoked standard in investment disputes. It is also the standard with the highest practical relevance: a majority of successful claims pursued in international arbitration are based on a violation of the FET standard. The concept of FET is not new but has appeared in international documents for some time. Some of these documents were nonbinding others entered into force as multilateral or bilateral treaties. Considerable debate has surrounded the question of whether the FET standard merely reflects the internationalminimum standard, as contained in customary international law, or offers an autonomous standard that is additional to general international law. As a matter of textual interpretation, it seems implausible that a treaty would refer to a well-known concept like the "minimum standard of treatment in customary international law" by using the expression "fair and equitable treatment." Broad definitions or descriptions are not the only way to gauge the meaning of an elusive concept such as FET. Another method is to identify typical factual situations to which this principle has been applied. An examination of the practice of tribunals demonstrates that several principles can be identified that are embraced by the standard of fair and equitable treatment. Some of the cases discussed clearly speak to the central roles of transparency, stability, and the investor's legitimate expectations in the current understanding of the FET standard. Other contexts in which the standard has been applied concern compliance with contractual obligations, procedural propriety and due process, action in good faith, and freedom from coercion and harassment. In short, meeting the investor's central legitimate concern of legal consistency, stability, and predictability remains a major, but not the only, ingredient of an investment-friendly climate in which the host state in turn can reasonably expect to attract foreign investment.

This study aims to make a contribution to the promotion of trade and economic development of South Korea, and, at the same time, call attention to the increasing trend of investment agreements concluded within Free Trade Agreements (FTA) by examining theoretically FTAs and dispute resolution and investigating systematically the conclusion procedure of agreements, and the system, institutions, and jurisdiction of dispute resolution, and presenting these findings to the government and investors involved. The most problematic aspect in the legal process of arbitration involving disputes over investment is that of arguments concerning the right of jurisdiction. When a dispute arises, even though an investor files for arbitration at an ICSID institution, the parties become involved in another energy-consuming argument even before proceeding to the hearing and decision of the original plan in cases in which the respondent of the dispute files an objection to the decision rights of the arbitral tribunal. As the main basis for this type of plea, the point of non-existence of jurisdiction is first raised where the applicable dispute does not fall under the range of investments defined in individual investment contracts or investment agreements such as a Bilateral Investment Treaty (BIT). To avoid an open-ended definition of investment for the range of investments, articles concerning investments in the FTA and NAFTA between Canada and the USA adopt the limited closed-list method. Article 96 of the FTA between Japan and Mexico applied the same abovementioned method of limited form of definition regarding range of investments and concluded BITs between member countries of APEC applied a similar method as well. Instead of employing the previously used inclusive definition, the BITs concluded between countries of Latin America and the USA are equipped with limited characteristics of an investment. Furthermore, to correspond with this necessary condition the three following requirements are needed : 1) fixed investment funding; 2) expected profits resulting from such investments; 3) and the existence of fixed risk bearing.

The congenital deformities of cleft lip and cleft palate have been known to afflict man since prehistoric time. Efforts to correct these abnormities have evolved over the centuries as scientific knowledge has advanced. Although there is no agreement as to when the surgery should be performed, most surgeons adhere to "rule of 10" : the infant must be 10 week old weigh 10 Ibs, have a hemoglobin value 10gm/dl and have a white blood cell count no greater than 10 $thousands/mm^3$. Consensus favors performing initial palatal surgery in the child when he is between 18 and 24 months old. The timing of cleft alveolus surgery is usually between 10 and 11 years old. In the period from 1992 to 1996, 38 patients with cleft lip and cleft palate treated at the department of oral and maxillofacial surgery, Chosun university, dental hospital were analysed clinically. The obtained results were as follows. 1. The ratio of male to female was 1.92 : 1 (25/23) 2. The ratio of cleft lip, cleft palate and cleft lip & palate was 1.5 : 1 : 2.5 (12/8/18) 3. The ratio of unilateral to bilateral cleft lip was 5 : 1 (25/5) 4. The ratio of left to right side in unilateral cleft lip was 1.5 : 1 (15/10)
