Broadcast-telecommunication bundling services provide customized services and reduce household telecommunication costs, contributing to the improvement of users' welfare. However, following the recent fierce competition of broadcast-telecommunication providers, the Korea Communications Commission, an organization that regulates promotional gifts and fee-reduction benefits to attract subscribers, has imposed a series of regulations. The excessive offering of promotional gifts can distort fair market competition and damage users. Yet if all bundling services are regulated uniformly, some benefits for users may be reduced, and the autonomous marketing competition of service providers may be restricted, thereby shrinking the entire communications market. Therefore, this study attempts to investigate domestic and foreign regulations on promotional gifts and other offerings related to broadcast-telecommunication bundling services, to analyze problems with respect to the current regulations and to propose an improvement plan. The study asserts that it is necessary to improve the violation decision criteria of the Korea Communications Commission and its regulations on broadcast-telecommunication service providers' promotional gifts in order to regulate the bundling services reasonably. In addition, it proposes a proper regulation of the OTS(Olleh TV Skylife) product, a new service emerging in the evolution of the bundling service type.

The paper looks at protecting copyright owners in Nigeria: a panacea for intellectual development. A descriptive survey design was adopted in carrying out the study. The sample size for the study was 112. Three research objectives guided the study. The study utilized a self-developed questionnaire for data collection. A total of 112 copies of the questionnaire were distributed to librarian and lecturers, out of which 108 copies were duly filled and returned, representing 96.4%. The collected data was arranged in frequency and analyzed using percentage and mean score. The findings revealed that protection of copyright will encourage creators of intellectual works, and that if authors are well remunerated there is likelihood of adequate availability of various publications to meet information needs of Nigerians. The result showed that the right to intellectual properties is one of the ways to encourage intellectual development. The finding revealed that copyright protection provides security for intellectual product and does not negatively affect the availability of intellectual materials. Based on the research findings, it was recommended that owners of intellectual property deserve good earnings for their intellectual works in order to promote Knowledge proliferation and availability so as to meet the reading needs of the citizens at the various levels. The study also recommended that all cases relating to copyright violation in our courts should be summarily dealt with. The study advocated that the provision on the punishment should be reviewed such that it could deter people from infringing on authors rights.

Discrete element modeling (DEM) in concrete technology is concerned with design and use of models that constitute a schematization of reality with operational potentials. This paper discusses the material science principles governing the design of DEM systems and evaluates the consequences for their operational potentials. It surveys the two families in physical discrete element modeling in concrete technology, only touching upon probabilistic DEM concepts as alternatives. Many common DEM systems are based on random sequential addition (RSA) procedures; their operational potentials are limited to low configuration-sensitivity features of material structure, underlying material performance characteristics of low structure-sensitivity. The second family of DEM systems employs concurrent algorithms, involving particle interaction mechanisms. Static and dynamic solutions are realized to solve particle overlap. This second family offers a far more realistic schematization of reality as to particle configuration. The operational potentials of this family involve valid approaches to structure-sensitive mechanical or durability properties. Illustrative 2D examples of fresh cement particle packing and pore formation during maturation are elaborated to demonstrate this. Mainstream fields of present day and expected application of DEM are sketched. Violation of the scientific knowledge of to day underlying these operational potentials will give rise to unreliable solutions.

Purpose: The purpose of this paper is to develop a systematic weighting procedure based on process capability indices method applying weighted mean squared error minimization (WMSE) approach to dual response surface optimization. Methods: The proposed procedure consists of 5 steps. Step 1 is to prepare the alternative vectors. Step 2 is to rank the vectors based on process capability indices in a pairwise manner. Step 3 is to transform the pairwise rankings into the inequalities between the corresponding WMSE values. Step 4 is to obtain the weight value by calculating the inequalities. Or, step 5 is to obtain the weight value by minimizing the total violation amount, in case there is no weight value in step 4. Results: The typical 4 process capability indices, namely, $C_p$, $C_{pk}$, $C_{pm}$, $C_{pmk}$ are utilized for the proposed procedure. Conclusion: The proposed procedure can provide a weight value in WMSE based on the objective quality performance criteria, not on the decision maker's subjective judgments or experiences.

It is true that every country which includes the developing country has planned own economic development through government subsidies. Korea also has developed their some major industry through supporting government subsidies. Under the WTO structure, however, government's specific supports for export firms come under prohibited subsidy and subsidy supporting must be based on WTO ASCM(Agreement on Subsidies and Countervailing Measures). The purpose of this paper was to study on the WTO ASCM and to analyze cases on the shipbuilding and Hynix DRAM dispute which Korean concerned major subsidy issue. Korea has been undergoing subsidy dispute with EU and U.S.A. concerned matter of shipbuilding and Hynix DRAM respectively. From this research results were as follow : First of all, the WTO ASCM introduced a definition of subsidy and divided subsidies into three categories and was legally bound through dispute settlement mechanism and implemented by all WTO members. Also, through analyzing cases, results were indicated that Korea wins a lawsuit against the matter of shipbuilding subsidy whereas losing the lawsuit against the matter of DRAM subsidy. It means that the case of shipbuilding subsidy do not violation WTO ASCM and the case of Hynix DARAM is against WTO ASCM. Additionally, as we see the dispute cases concerned Korean industry, it is necessary that government should operate subsidies which were provided for certain governmental policy as consisted with WTO ASCM.

Clock skew scheduling is one of the essential steps to be carefully performed during the design process. This work addresses the clock skew optimization problem integrated with the consideration of the inter-dependent relation between the setup and hold times, and clock to-Q delay of flip-flops, so that the time margin is more accurately and reliably set aside over that of the previous methods, which have never taken the integrated problem into account. Precisely, based on an accurate flexible model of setup time, hold time, and clock-to-Q delay, we propose a stepwise clock skew scheduling technique in which at each iteration, the worst slack of setup and hold times is systematically and incrementally relaxed to maximally extend the time margin. The effectiveness of the proposed method is shown through experiments with benchmark circuits, demonstrating that our method relaxes the worst slack of circuits, so that the clock period ($T_{clk}$) is shortened by 4.2% on average, namely the clock speed is improved from 369 MHz~2.23 GHz to 385 MHz~2.33 GHz with no time violation. In addition, it reduces the total numbers of setup and hold time violations by 27.7%, 9.5%, and 6.7% when the clock periods are set to 95%, 90%, and 85% of the value of Tclk, respectively.

According to the current law of national health insurance, the Minister of Health and Welfare can impose a suspension of business or license, and a fine with medical institutions who violate the law. In case that medical institutions raise an action for ity with each penalty, they ask for replacing the suspension of business with a fine during the pendency of the action. But there is a long gap of time between an offense and administrative measures. One violation cause several types of administrative measures (suspension of business or fine, suspension of license etc.) and different government departments impose these penalties. It takes a lot of time to organize their opinions and they are liable to impose penalties after considerable space of time because of overwhelming tasks. Then the medical institutions can sustain a loss by getting unexpected administrative measures after their offense against the law. Thus, this article review whether extinctive prescription apply to the right of imposing fine on the law of national health insurance or not. Meanwhile, we have no regulations imposing a same fine to co-representatives of medical institution who infringe the law of national health insurance. On this point, this study review whether they have equal duty on that or not.
