  • In modern manufacturing practice it is sometimes necessary to send products to another country for special processing which cannot be performed inside the territory of the zone and Outward Processing(OP) covers such situation. What's more, process and Rules of Origin(RoO) of OP is implicated in Korea' Free Trade Agreement(Korea-Singapore, Korea-EFTA and Korea-Asean FTA) because of the goods to be producted in Kaesong Industrial Complex. Thus, In this paper analyse a implication of OP's process and RoO focused on the two fold : (1) provide an overview of the objectives, types, effects of Outward Processing described in customs law and FTA provisions of EU and Korea; (2) present a comparative analysis of EU and Korean rules; (3) offer an appropriate proposal to Korea-EU FTA negotiation.

  • This paper addresses the issue of time-difference-of-arrival (TDOA) estimation for complex noncircular signals. First, under the wide-sense stationary assumption, we derive the maximum likelihood (ML) estimator and the Cramer-Rao lower bound for Gaussian noncircular signals in Gaussian circular noise. The ML estimator uses the second-order statistics information of a noncircular signal more comprehensively when compared with the cross-correlation (CC) and the conjugate CC estimators. Further, we present a scheme to modify the traditional signal-selective TDOA methods for noncircular signals on the basis of the cyclostationarity of man-made signals. This scheme simultaneously exploits the information contained in both the cyclic cross-correlation (CCC) and the conjugate CCC of a noncircular signal.

  • The exhaust gas flow in the inlet collector of close coupled catalyst(CCC) adapted to the exhaust manifold is very complex flow because the exhaust gas is a pulsation flow with several port flow. The distribution of gas flow and temperature in inlet collector effect to the efficiency of catalytic converter. In this study, it measures temperatures on several point in inlet collector with two kind of inlet collector volume. And it analyzes with CFD to exhaust manifold and close coupled catalyst for temperature and flow. Comparing to measured and analyzed result, it find increasing of collector volume effects to catalyst temperature distribution and uniformity of catalytic converter

  • To decrease the bolting rate of Angelica gigas, The growth inhibitors such as MH, Pp333 (paclobutrazol) and CCC(chloroniequat or Cycocel) were treated twice with the interval of 20 days atthe forming stage of flower bud.Growth and bolting rate in plot treated inhibitors were retarded and decreased, and the yield ofroots was also decreased compared with non - treatment. The treatments of MH and Pp333 amongthree inhibitors showed the better effects in decreasing the bolting than that of CCC, but they did notshow the significant in the yield and contents of decursin among each of them.In order to improve the decreasing effects by chemicals, selection of suitable reagents, concentrationand number of treatment should be investigated.

  • Experimental studies were performed to understand the flow characteristics in the exhaust system and improve the THC emission characteristics by optimizing the flow in the exhaust manifold and CCC in a SI engine. For this purpose, the flow characteristics in the exhaust systems with two types of exhaust manifolds(STD and New Type) were measured by using LDV technique under various engine condition. It was found that the flow characteristics in the New Type exhaust manifold was more desirable in a view point of heat loss reduction from the exhaust gases. The vehicle emission tests showed that the THC emission in the New Type exhaust manifold was decreased by 12%.

  • How can a train move? While a car is driven by a driver who gets the traffic information and takes the road, a train is operated on the designated(or predetermined) track by the operator or the control center. There have been a great deal of changes and evolutions in the railroad environment. Along with these transitions, there have been also a considerable amount of changes in the control center. There has been no detailed analysis for the control center even though its importance has been recognized. It goes without saying that CCC(Central Control Center)'s importance as the core of the train driving system. Such an importance is true for the automated driving system such as the light rail system. Therefore this paper analyzes the CCC of AREX(Airport Express) from the various aspects, i.e., organization, personnel assignment, the way of working, qualification and job analysis for the operator.

  • In order to examine the effect of growth regulators on flower bud formation and anthesis, various growth regulators were applied during the initiation and growthstages of flower bud development in Camellia. The inhibitor CCC increased flowerbud formation. But gibberellin had a strong suppressing effect of flower budformation while it stimulated elongatien of shoots. On the other hand, gibberellinpromoted the growth of flower buds and hastened anthesis, while other growthregulators had no effect.

  • Guggulsterone, a hypolipidemic natural agent, is produced in resin canals of the plant Commiphora wightii. In this study, the stimulatory effects of growth retardants [ALAR (N,N-dimethylaminosuccinamic acid) and CCC (chlormequat chloride)] and fungal elicitor on guggulsterone accumulation in cell cultures of C. wightii are reported. CCC at $1\;mg\;l^{-1}$ enhanced guggulsterone content (${\sim}123\;{\mu}g\;l^{-1})$ when added on the fifth day after inoculation, while ALAR at $2.5\;{\mu}g\;l^{-1}$ increased guggulsterone content (${\sim}116\;{\mu}g\;l^{-1}$) when added on the tenth day. In a two-stage fed-batch process, combined treatment with fungal elicitor and growth retardant caused a significant increase (${\sim}353\;{\mu}g\;l^{-1}$) in guggulsterone content in cell cultures after 17 days of growth. This represents an approximately fivefold increase over the guggulsterone contents in initial cultures of this plant.

  • In the control of CNC machine tools, it is significant for precise machining to reduce the contour error. The object of servo-control is reduction of contour error and tracking error. In past studies, there were two approaches to control a servo-system. One was to eliminate axial tracking errors, and the other was to control contour errors. The Cross-coupled controller(CCC) was introduced fro ma veiwpoint of contour error model. Recently, for machining part with free form surfaces, we propose a new contour error model based on curve interpolator. It is presented here that performance of CCC using proposed model is enhanced. Therefore, we can make more precise parts with the curve interpolator and the new contour error model.
