Recently graphic hardwares have been developed remarkably, and domestic and foreign game users have demanded realistic and spectacular game graphics. Graphic special effects are one of methods to satisfy these requests, but we have not known any cases where graphic special effects are general and thus reusable. Based on the implementation of our graphic special effect engine and its application cases, this paper describes how to easily exploit graphic special effects in developing games. We define a standard file format in which special effect data can be saved and loaded, and thus those data can be reused easily. We also show that developers can test or preview special effects by exploiting our graphic special effect tool even before producing games.

In general universal service in telecommunications means a regulatory tool to secure the availability of basic communication services like fixed telephony at an affordable price throughout a country. A re-evaluation of the scope of existing universal service, however, is becoming a core issue as the penetration and usage of broadband and mobile communications matures and a new ICT ecosystem emerges. This study examined whether the universal service polices in Korea need adapting and updating to include broadband and mobile telephony in the universal service, which is based on the necessary and sufficient conditions derived from previous research and foreign countries' experiences : geographical ubiquity of a certain service and the market's ability to provide the service. The result shows the nationwide ubiquity of broadband and mobile communications exists but the ultimate goal pursued by universal service polices trying to make them available and affordable for all is being fulfilled by market dynamics in Korea. Thus, the inclusion of both services in the scope of universal service is regarded as an unnecessary regulation at present time and the expansion of universal service could be addressed as a long-term issue depending on market conditions in the future.

According to the price-decline effect, the art auction prices are known to decrease with the order of auction sale. Our empirical study investigates the presence for the price-decline effect using the data for Korean antique art hosted by the Seoul Auction in September, 2015. We apply the Hedonic price model to the data and examine the relation between the sale order and auction price. Our empirical evidences show that the well-known price decline effect is not present for the case of Korean antique auction in 2015. We confirm our results by estimating the ordered probit model. From the view of the price-decline effect, our results suggest that the Korean antique auction data exhibits different characteristics from most of the foreign art auction data.

최근 카자흐스탄이 러시아나 서구제국들이 아닌 중국과의 에너지 외교에 큰 진전을 보이고 있듯이, 중국은 미국이나 러시아를 자극하지 않은 채로 중앙아시아제국들과의 경제협력을 확대하고 이를 통한 성공적인 에너지안보체제를 구축하고자 한다. 그러나 역사적으로 일정지역에 중국인들의 진출이 늘어나거나 중국인들의 경제적 영향력이 제고되면, 중국정부의 대상지역에 대한 영향력도 제고되었다는 사실로 미루어, 중국의 해외투자 또는 해외이주와 연관된 중국정부의 연계전략에 대한 주의가 요구된다. 중국정부는 해외투자 또는 해외이주지원이라는 명목으로 제주도의 해군기지 주변 강정마을에 대한 부동산 구매를 시도하고 있으며, 그 밖의 한국 내 미군기지 주변에도 중국인타운을 형성하는데 보이지 않는 정부차원의 지원을 확대하고 있다. 이와 같은 현상은 일본 내 미군기지, 특히 오키나와 미군기지 주변과 사스마섬의 일본 자위대 기지 주변에서도 동일하게 전개되고 있다. 이런 중국정부의 의도는 한국과 일본에 주둔하고 있는 미군기지에 대한 견제장치인 동시에 해당지역 주민들에 대한 중국의 영향력 제고를 목적적 결과물로 노정하고 있는 것이다. 중국자본과 중국인들의 한국과 일본 현지진출은 경제적 이해를 넘어서는 외교적, 군사적 문제까지도 야기할 수 있고 이로 인한 국가간 갈등요인이 제고될 수 있는 만큼, 중국의 해외투자 연계전략에 대한 보다 철저한 관리 감독이 필요하다.

In recent, as Republic of Korea has been interested in environmental problem increasingly and became a member of many organizations or institutions related to environmental preservation such as a Ramsar convention, fundamental and completed methods to prevent ground water's drying up and leakage in tunnel excavation are requested. In this paper, we have studied the anticipated problems by tunnel excavation under the wetland and described the effective designed method to maintain the wetland's ecosystem environment. To accomplish this purpose, firstly, we investigated the wetland's ecosystem, ground's hydraulic properties and analysed the foreign similar case for tunnel excavation near the wetland. And by numerical analysis, we analyzed the runoff and infiltration quantity of water and hydraulic behaviour properties by saturation and unsaturation concept in rock mass and wetland. Finally, we established the effective countermeasure to minimize the ecosystem's bad influence by tunnel excavation.

Human cysticercosis is an infestation with C. cellulosae, the larval stage of the tapeworm T. solium. It prevails in regions of poverty and where personal hygiene is poor. They can lodge in almost any tissue, but cysticerci are most frequently found in brain, skeletal muscle, subcutaneous tissues. We experienced a 41-year old male with $5{\times}12cm$ sized movable non tender brownish hard mass at lateral abdominal wall. The laboratory study didn't show any specific symptoms except peripheral blood eosinophilia and positive parasite ELISA screen for cysticercosis. The ultrasonogram revealed multiple ill-defined mixed echoic inflamatory lesion. Excisied cyst showed multiple severe foul-odor gelatinous subcutaneous mass. Microscopic examination disclosed necrotic body with foreign body reaction, massive eosinophilia and dead parasitic organism, compatible with cysticercosis. There was no evidence of recurrence during 12 months follow-up.

The significant increase in international trade over the last few decades has been accompanied by an increase in the number of commercial disputes between Korea and India. Understanding the Indian dispute resolution system, including arbitration, is necessary for successful business operation with Indian companies. This article investigates characteristics of India's Arbitration and Conciliation Act in order to help then traders who enter into business with Indian companies to settle their disputes efficiently. The Arbitration and Conciliation Act(1996) based on the 1985 UNCITRAL Model Law on International Commercial Arbitration and the UNCITRAL Arbitration Rules 1976, has a number of characteristics including the following: (i) this act covers ad hoc arbitration and institutional arbitration (ii) parties to the arbitration agreement have no option except arbitration in case of any dispute (iii) the parties can choose their own laws, places, procedures, and arbitrators (iv) the decision of the arbitrators is final and binding (v)role of the court has been minimized and (vi) enforcement of foreign awards is recognized. However, there have been some court decisions that have not been in tune with the spirit and provisions of the Act. Therefore, Korean companies insert the KCAB's standard arbitration clause into their contracts and use India's ADR(Alternative Dispute Resolution) Methods to strategically resolve their disputes. Additionally, Korean companies investigate Indian companies' credit standing before entering into business relations with them.

Recently, in accordance with the commercialization of novel radio frequency utilization technologies, the radiated power must be rigorously limited for the purpose of protection of wireless facilities against frequency jamming or interference and for maintaining the quality of communication service. At present, the output power is measured from the conducted power for the domestic measurement criterion but is not a real radiated power and inaccurate. So, it is peformed to survey the more precisely accurate measurement scheme and analyze its criterion and methodology in comparison with foreign one. As a result of surveying and analyzing, it is concluded that the U.S. and E.U. is actually using the measurement method in consideration of terms of the Equivalent Isotropic Radiated Power(EIRP) and Effective Radiated power(ERP). In case of the frequency below 1 GHz, the half wave-length dipole antenna is used to measure the ERP and above 1 GHz the horn antenna as a reference antenna is used to measure the EIRP. Therefore, for the domestic purpose it is also necessary to take EIRP and ERP into consideration as a measurement criterion in order to make an accurate measurement and regulation.
