The International Chamber of Commerce has been the world's leading organization in the field of international commercial dispute resolution. Established in 1923 as the arbitration body of ICC, the International Court of Arbitration has pioneered international commercial arbitration as it is known today. The ICC International Court of Arbitration is the world's foremost institution in the resolution of international business disputes. While most arbitration institutions are regional or national in scope, the ICC Court is truly international. The purpose of this paper is to examine their advantages and to introduce main contents provided in ICC Rules of Arbitration as follows; First, before the actual merits of the case can be addressed, the Arbitral Tribunal must first draw up the Terms of Reference. The Terms of Reference should include the particulars listed in the ICC Rules. Apart from the full names and description of the parties and arbitrators, the place of arbitration and a summary of the parties' respective claims, they contain particulars concerning the applicable procedural rules and any other provisions required to make the Award enforceable at law Second, the Scrutiny is a fundamental feature of ICC arbitration and is one that distinguishes it from the other major international arbitration rules. The scrutiny system has two aspects ; the first is to identify or modify the defects of form, while the second is to draw the arbitrators' attention to points of substance. Third, as soon as practicable, the Court fixes an advance on costs intended to cover the estimated fees and expenses of the arbitrators, as well as the administrative expenses of ICC. Specially, the advance on costs fixed by the Court shall be payable in equal shares by the Claimant and Respondent. Finally, the parties are also free to select the arbitrator or arbitrators of their choice. The Court or the Secretary General confirms arbitrators nominated by the parties. Taking a step forward, to upgrade the quality of the award of KCAB, it is desirable to consider how to incorporate the main contents of the ICC Arbitration into Korea Commercial Arbitration Rules.

This study proposed a revision of standard sizing system for infant clothing to provide exact information for consumers and manufacturers. The size designation was set up by compensating the defect of existing system. Basic body measurement and reference body measurement were analysed according to size designation. The ages of the infants ranged from 0 to 36 month in accordance with safety standard of KC Self-Regularity Safety Confirmation. The results are as follows: Size designation for infant clothing was based on height that was basic body measurement. Chest girth, waist girth, head girth, arm length, foot length and weight were also analysed according to age of the month. It was proposed that height could be written alone and height with age of month did together for size designation. Size intervals of basic and reference body measurements were fixed as follows: size intervals are 5 cm in height, 2 cm in chest girth, 2 cm in waist girth, 1 cm in head girth, 2 cm in arm length, 0.5 cm in foot length and 2 kg in weight. The distributions of height and chest girth showed normal distributions. As height was taller, chest girth was also bigger. But the distribution of waist girth didn't show remarkable change with age of month. The distributions of arm length and weight showed remarkable difference with growth in 0~9 months, but the amount of growth variation got less in 12~18 months.

전공서적 이용실태조사에 따르면, 대학생들은 한 학기당 평균적으로 6.4권의 전공서적을 구매하고 이를 위해 9.4만원을 지출한다. 그러나 이렇게 구입한 전공서적의 절반 가까이는 사용되지 않고 방치되고 있다. 그래서 많은 학생들이 정가를 주고 새 책을 구입하기 보다는 중고책 거래를 통해 전공서적을 구하고 있다. 기존의 중고 전공서적 거래를 지원하는 플랫폼들은 판매를 위한 기본 기능들은 제공하고 있지만, 전공별 교재 추천, 참고도서 추천 기능 등이 제공되지 못하고 있다. 본 연구에서 지역성을 반영한 전공별 교재 추천, 참고도서 추천, 위탁 거래 기능 등이 제공되는 중고 전공서적 거래 플랫폼 BookCue를 개발하였다. 본 플랫폼을 이용함으로써 방치된 전공서적들의 거래 활성화를 통한 대학생들의 교재구매비 경감과 환경보전에 기여할 수 있을 것으로 기대된다. 향후 본 플랫폼은 전공서적뿐만 아니라 대학생들을 위한 지역 내 다양한 물품을 거래하는 플랫폼으로 확대될 수 있을 것이다.

General drug prices involve three stages: shipment stage, wholesaler stage and retail stage. Policies on drug price differ from country to country. Shipment stage prices are tightly regulated in countries like France and Netherlands. They are free in only a minority of advanced countries, even if these include some major players such as the US, Germany and, in a very limited sense, Japan. The situation in the UK is very complex with a semi-free system, where drug companies are free to set their own prices but cannot exceed a predetermined profit ceiling. Mark-up at both wholesaler and retail stages is formally admitted in most countries observed. Apart from the general drug prices, reimbursement price of insured drugs has been major policy concerns. Most countries reviewed in this study has exerted some control over reimbursement prices, but differ both in the way how and in the extent to which prices are admitted or fixed. Price fixing has been used in France and Japan. Some countries have transformed their system over time, particularly to move to reference pricing in the last decade. This mechanism has empowered the customer, and improved price competition on the market. Referring to the drug price policies in the advanced countries, this study makes some suggestions for the redirection of Korean price policy for reimbursement drug in health insurance as follows: to match appropriate policy tools to each policy goal; to maximize market mechanism through effective reimbursement price fixing which admits mark-ups in wholesaler and retail prices; to introduce reference pricing system in order to redirect patient's demand with a financial incentive to choose the best-priced drugs and to save the finance of health insurance; and to strengthen surveillance and monitoring mechanism in the drug market.

This paper presents an architecture for wireless sensor networks (WSNs) with blind source separation (BSS) applied to retrieve the received mixing signals of the sink nodes first. The little-to-no need of prior knowledge about the source signals of the sink nodes in the BSS method is obviously advantageous for WSNs. The optimization problem of the BSS of multiple independent source signals with complex and noncircular distributions from observed sensor nodes is considered and addressed. This paper applies Castella's reference-based scheme to Novey's negentropy-based algorithms, and then proposes a novel fast fixed-point (FastICA) algorithm, defined as the reference-signal negentropy complex FastICA (RSNT-cFastICA) for complex-valued noncircular-distribution source signals. The proposed method for the sink nodes is substantially more efficient than Novey's quasi-Newton algorithm in terms of computational speed under large numbers of samples, can effectively improve the power consumption effeciency of the sink nodes, and is significantly beneficial for WSNs and wireless communication networks (WCNs). The effectiveness and performance of the proposed method are validated and compared with three related BSS algorithms through theoretical analysis and simulations.

Purpose: The aim of this study was to compare the coordinates of anatomical landmarks on cone-beam computed tomographic (CBCT) images in varied head positions before and after reorientation using image analysis software. Materials and Methods: CBCT images were taken in a normal position and four varied head positions using a dry skull marked with 3 points where gutta percha was fixed. In each of the five radiographic images, reference points were set, 20 anatomical landmarks were identified, and each set of coordinates was calculated. Coordinates in the images from the normally positioned head were compared with those in the images obtained from varied head positions using statistical methods. Post-reorientation coordinates calculated using a three-dimensional image analysis program were also compared to the reference coordinates. Results: In the original images, statistically significant differences were found between coordinates in the normal-position and varied-position images. However, post-reorientation, no statistically significant differences were found between coordinates in the normal-position and varied-position images. Conclusion: The changes in head position impacted the coordinates of the anatomical landmarks in three-dimensional images. However, reorientation using image analysis software allowed accurate superimposition onto the reference positions.

본 논문에서는 비 선형 단상부하에 의해 발생하는 전류 고조파를 보상하기 위한 단상능동전력필터의 새로운 제어방법을 제안한다. 부하전류에 시간지연을 주어 임의의 두 번째 상을 생성한 후 단상시스템을 두 상을 갖는 시스템으로 만들어 복소계산을 가능하게 한다. 기존의 방법은 부하전류를 1/4 T(T는 기본파의 주기) 만큼 지연시켜서 가상의 상을 만들었지만, 본 논문에서 제안하는 방법은 저역통과필터가 상 지연의 특성을 가지는 것을 이용하여 필터를 통과한 지연된 위상을 가진 새로운 신호를 두 번째 상으로 이용하였다. 두 개의 위상이 다른 상이 존재하므로 고조파 전류의 순시계산이 가능하게 된다. 기존의 고정좌표계를 이용하여 순시무효전력이론을 적용하지 않고, 본문에서는 전원주파수에 동기하는 회전좌표계를 사용하여 순시계산을 하였고, 보상전류 지령치를 구하였다. 전류원으로 사용되는 RL부하에 대하여 시뮬레이션과 실험을 수행하였고, 제안된 제어법의 유효성을 입증하였다.

Purpose: Proton therapy has different relative biological effectiveness (RBE) compared with X-ray treatment, which is the standard in radiation therapy, and the fixed RBE value of 1.1 is widely used. However, RBE depends on a charged particle's linear energy transfer (LET); therefore, measuring LET is important. We have developed a LET measurement method using the inefficiency characteristic of an EBT3 film on a proton beam's Bragg peak (BP) region. Methods: A Gafchromic EBT3 film was used to measure the proton beam LET. It measured the dose at a 10-cm pristine BP proton beam in water to determine the quenching factor of the EBT3 film as a reference beam condition. Monte Carlo (MC) calculations of dose-averaged LET (LET_d) were used to determine the quenching factor and validation. The dose-averaged LETs at the 12-, 16-, and 20-cm pristine BP proton beam in water were calculated with the quenching factor. Results: Using the passive scattering proton beam nozzle of the National Cancer Center in Korea, the LET_d was measured for each beam range. The quenching factor was determined to be 26.15 with 0.3% uncertainty under the reference beam condition. The dose-averaged LETs were measured for each test beam condition. Conclusions: We developed a method for measuring the proton beam LET using an EBT3 film. This study showed that the magnitude of the quenching effect can be estimated using only one beam range, and the quenching factor determined under the reference condition can be applied to any therapeutic proton beam range.

표면영상유속계를 이용한 유속 측정 시 하천의 넓은 영역을 경사지게 촬영하기 때문에 필연적으로 영상 왜곡이 발생하게 된다. 이와 같이 경사영상을 정사영상으로 변환하는 방법으로 수표면과 동일한 평면상의 참조점 좌표를 이용하는 2차원 투영 좌표 변환법을 사용할 경우 홍수 시 수위가 변할 경우 대응이 어렵다는 한계가 있다. 이에 본 연구에서는 수위가 변하더라도 참조점을 재설정할 필요가 없는 경사영상 왜곡 보정 방법을 개발하였다. 본 연구에서 개발한 기법은 높은 위치에 설정한 참조점의 좌표와 카메라의 좌표, 그리고 카메라의 수표면 사이의 연직거리 간의 기하학적인 관계를 이용해 수위 변화에도 대응할 수 있는 경사영상 보정 기법이다. 본 연구에서 개발한 영상 왜곡 보정 방법의 검증을 위해 실규모 하천 실험을 수행하였으며, 참조점 변환식에 대한 검증과 표면유속 측정 결과에 대한 검증을 수행하였다. 검증 결과 개발 기술의 경사영상 보정 정확도는 97% 이상을 나타냈고, 유속 검증 결과 개발 기술을 적용하여 산정한 유속을 비교한 결과 약 4% 이내의 차이를 보이는 것으로 나타나 높은 정확도 확보가 가능한 것으로 나타났다. 따라서 개발 기술을 영상 기반의 고정형 자동유량계측 시스템에 적용한다면 수위가 급변하는 홍수 시 유량측정의 정확도를 개선할 수 있을 것으로 기대한다.
