Recently, a Game Shut-down policy, partially limiting the time for the use of online game service, has been implemented in order to protect the youth from the excessive use of games by limiting their access to games in the late hours, based on the serious side effects of online games on the youth. However, the effectiveness of a Game Shut-down policy becomes a social issue. Thus, this study aims to investigate the alternative policies through the levels of the communications suggested by the theory of excellence, for the successful implementation of the policy. As a result of the study, the government and students, the recipient of those policies, need to strengthen their two-way communication in respect of the Game Shut-down policy, breaking from the existing views on the perception. The problem is that the current government's way of the communication for the Game Shut-down policy is one-way and it is aiming at achieving the objectives only. Thus, the communication in this manner will cause the side effect. 'the opportunistic violation of the system in the future', even if the students seemingly accept the system. Two-way communication will enhance the motivation for the voluntary acceptance of the system and lower the motivation for the opportunistic violation of the system. Thus, the government needs to strengthen two-way communication in the future.

Recurrent event data occurs when a subject experience the event of interest several times and has been found in biomedical studies, sociology and engineering. Several diverse approaches have been applied to analyze the recurrent events (Cook and Lawless, 2007). In this study, we analyzed the YTOP(Young Traffic Offenders Program) dataset which consists of 192 drivers with conviction dates by speeding violation and traffic rule violation. We consider a subject-specific effect, frailty, to reflect the individual's driving behavior and extend to time-varying frailty effect. Another feature of this study is about the redefinition of risk set. During the study, subject may be under suspension and this period is regarded as non-risk period. Thus the risk variables are reformatted according to suspension and termination time.

In this paper, we propose an analytic method for dimensioning of traffic descriptors at the leaky bucket-based UPC for VBR MPEG video traffic on ATM networks. We analytically derive cell violation probabilities at the UPC by using the proposed scene-based video traffic model, and then we show that it is possible to select sets of traffic descriptors that have the same required violation probability. For two example video traces, numerical results show that our proposed traffic descriptors dimensioning method can approximate well the simulation-based traffic control results of the real video traces. When the effective bandwidth allocation method of an ON/OFF model is used for the call admission control in the networks, we present an efficient traffic descriptor selection method by studying the allocated bandwidth to each possible traffic descriptor set.

"The prohibition of careless or reckless flight" is the regulation specified not only in the national air law but ICAO ANNEX and FAR. This article(item) has not been categorized properly unlike other items and the question such as why this is described as a fundamental and essential act can be answered only by the party subjected to administrative measures in case of Korea and this kind of violation is so rare that it is not easy to understand the legal meaning and the function of the term, "The prohibition of careless or reckless flight" In case of U.S where aviation cases are common, the distinction between the term "careless" or "reckless" operation depends on whether to recognize the given situation. Some incidents happened by failing to aware NOTAM, violating ATC, or T/W landing where a pilot did not recognize the violation itself are considered to be "Careless" flight. Others such as low altitude high speed flight, approximate flight, Rejecting ATC instruction where a pilot intends to or is remiss in safety are regarded as "Reckless" flight. For pilots who are required to take the highest level of care from preparing for flight to stopping engines or completely disembarking passengers from a plane, the clear understanding of the most basic concept of "careless" or "reckless" flight should be emphasized for the safe flight and it is the time for the authorities to set a standard for proper measures by definite legal interpretations.

Purpose: This paper examines the theoretical grounds for the disclosure of the Korea Fair Trade Commission. Three central measures of the disclosure are scrutinized: The interconnected status of affiliate companies, the important matters of private affiliates, and the large internal transactions. Contemplating on three measures, respectively, we review the rationale and derive policy implications. Research design, data, and methodology: Collecting the data of violation rates and remedial measures, we analyze the intensity of the disclosure enforcement. These statistics are critically reviewed by the economic literature of mandatory disclosure. Results: Statistics evince that the Korea Fair Trade Commission has enforced the regulatory disclosure quite successfully. Violation rates of the disclosure has declined from the outset. It demonstrates that the Korea Fair Trade Commission has enforced those measures satisfactorily for about a decade. But we cannot ascertain empirically whether the regulatory disclosures are socially and economically beneficial. To evaluate the effect of the regulatory disclosures precisely, we need a further empirical investigation. Conclusions: Despite the lack of policy evaluation, this study suggests complementary measures for current disclosures. First, disclosure of executive compensation in privately held subsidiaries must be introduced. Second, the controlling shareholder/manager should be responsible for information disclosure on foreign subsidiaries.

This paper presents a knowledge based system to solve reactive power/voltage control problem in a power system. A need is recognized for new methods to alleviate a bus voltage limit violation more quickly when a power system becomes an emergency state due to contingency. To cope with this object, a set of indices concept which is used to make bus order list of reactive power injection priority is introduced. A set of indices, based on the overall system conditions, consists of steady state stability index, reactive power transmittance indes, voltage severity index and generator fuel cost index. This scheme and empirical rules of the knowledge on the basis of the human expert result in fast decision-making of the reactive power compensation devices since only the amount of devices is determined by the inference in the knowledge based system when the voltage violation is detected. In this approach, control devices such as shunt capacitor (reactor), transformer tap settings and generator voltages are utilized. Also the developed system herein can be used to minimize control action taken or generator fuel cost according to the user's option on the weighting factor. The results of a case study are also presented.

The third sex implying a mismatch between sex and gender has been regarded as an extreme socio-cultural violation. In its earlier version, such a violation was expressed by cross-dressing; Women's cross-dressing was thought to invoke eroticism, while men's cross-dressing was considered comic or delinquent. However, as feminism developed more with the homosexual identity expressed openly, the third sex began to be visual. Thus, in 1990's, some homosexual monies began to develop to be pluralized enough to suggest the third sex and thereby, change the negative sex into a positive one. In this study, such a pluralization is discussed in terms of invisibility, dichotomy and androgyny. The cross-dressing movies show females in male attire or males in female attire to reflect the third sex. The cross-dressing may be divided into men's playful cross-dressing, women's political cross-dressing and homosexuals'cross-dressing or 'drag'. Gender identity is not an attribute fixed by some physical characteristics, but it tends to be changed or expanded by some social factors over time. In short, it may be a flexible, plural, individual and self-introspective attribute. Movies present diverse types of gender identities, and in particular, the movie costumes specify them. In other words, the costumes may be model means expressing the gender identities, and the gender identities shown in the movies tend to be imitated, re-created or assumed by the audience.

This study compares the SGA and CISG to find out the difference of the criteria for calculating damages. and it intends to give some important points in trade practice. The damages is intended to compensate the victim for the breach of contract but there are differences between SGA and CISG as follow. First, the SGA and CISG have the same purpose of claiming damages. Both laws and regulations are subject to a full indemnification to compensate for the breach of the contract by the amount equivalent to the loss suffered by the victim. Second, in the general principle related to the calculation of damages, both law enforcement officials are required to be able to predict damages caused by breach of contract. In the case of SGA, however, a foreseeability test or remoteness of damages is required for the relationship between the contract violation and the loss. In other words, it can be said that the causal relation between the contract violation and the damage is strictly applied rather than the CISG. Finally, both laws and regulations of SGA and CISG have a big difference in criteria for calculating damages. In the CISG, after the contract is canceled, it is classified according to the existence of the alternative transaction and the damage amount is calculated based on the contract price. On the other hand, the SGA estimates the loss based on the market price at the delivery of the goods, reflecting the change in the market price instead of the contract price of the goods.

Present study examines L1 transfer effect and UG involvement in the acquisition of binding properties of Korean as second language (L2). The study especially investigates i) whether knowledge from different L1s (English and Chinese) affect the interpretation of binding in Korean as L2 and ii) whether L2 learners of Korean differentiate two Korean anaphors like Korean monolinguals do, based on their knowledge of universal form-function correlation of anaphors. 53 post-puberty L2 learners of Korean with English or Chinese L1, together with 30 Korean monolinguals, were tested over Truth Value Judgment Task with stories, composed of Korean sentences representing various types of binding with two Korean reflexives - caki and caki-casin. The results showed some effect of L1 transfer, though not always. Overall, late L2 learners of Korean seem to know the difference between the two anaphors in their properties related to form-function correlation, though their performance level was lower compared to Korean monolinguals. Detailed pattern of the results and the role of UG in the interpretations of Korean reflexives are also discussed.

In order to determine the violation of right of light impact at adjacent residential area by high-rise building, analysis on the right of light for high-rise residential commercial complex building block at Gahngnam-ku, Seoul, Korea was carried out using Google Sketchup Pro. After the analysis th sunshine duration of B apartment decreased from 5 hours 16 minutes 3 hours 48 minutes by I hour 42 minutes after construction. It shows that the total sunshine duration is less than the Seoul City Government Standard which is more than 4 hours a day, or more than 2 consecutive hours. Lowering the heights of apartments by 54m would increase the total sunshine duration which would meet the Seoul City Government Standard by four hours seven minutes. Problems that rna lead to the violation on the right of light in the adjacent area should be discussed in advance and minimized by analyzing the right of light among buildings and structures which are scheduled to be constructed on the site during construction penni! process when high-rise building is proposed.
