Most of Korean survey institutions adopt quota sampling for telephone surveys based on region, gender and age-band. In weekdays, it is well blown that there exist substantial differences in day time in-house rate by individual's socio-demographic attributes. So, quota sampling may induce systematic respondent selection bias. To solve the problem, we propose "time-balanced quota sampling" in which interviewer's call time-band is added as an quota variable. Furthermore, we propose "time-balanced quasi-quota sampling" which is derived by partially relaxing evening time quotas in time-balanced quota sampling. We compare the conventional and the newly proposed quota sampling schemes by drawing Monte Carlo samples from the hypothetical population for which the Korea 2004 time use survey data is assumed.

In this study, a conjoint analysis was conducted to derive a combination of fishing quota management system by fish species preferred by fishermen. In the analysis, detailed levels were set according to each attribute of the system. For analysis, this study conducted a design question survey for conjoint analysis on 303 fishermen engaged in fishing activities in the offshore and coastal sea. The Conjoint analysis was conducted on all fishermen, offshore fishermen and coastal fishermen. In addition, an analysis was conducted on TAC system participants and non-TAC system participants, and the targets were classified for comparison according to the characteristics of fishermen. Fishermen's preference for the system confirmed for six attribute ("catching fish even if there is no fishing quota", "how to allocate fishing quota", "fishing quota management agency", "upper limit of fishing quota," "Possibility of Trading in the Fishing Quota", and "Application of Other Regulations.") and the detailed level of each attribute. As a result of the analysis of the importance of attributes, fishermen thought that "fishing quota management agency (24.1%)" was very important, and "catching fish even if there is no fishing quota (23.9%)" and "how to allocate fishing quotas (22.9%)" were also given some importance.

This paper studies the introduction of flood quota system for efficient flood prevention. In the present system where local governments decide its flood prevention independently, the optimal flood prevention in a river basin can not be achieved. Thus, the flood quota system is necessary. In deciding the flood quota for each local government in a river basin, its social and economic characteristics as well as geographical feature of the area should be considered. In order to promote the cooperation among local governments in a river basin, the flood quota is necessary to be accompanied with the trading system of the quota.

Recently our government intended to change the present fisheries management system into the allocated catch quota system, which is to increase the income of fishermen and to recover the depleted resources up to a desirable level. This paper is to find out the difficulties of introducing the allocated catch quota system into our fisheries mangement system and to reduce the possible errors for the enforcement of this system. The allocated catch quota system can be devided by two kinds, the one is to allocate among industries or fisheries with total allowable catch(TAC) and the other is to allocate among fishermen or individual vessels with individual fish quota(ITQ). The latter is a much advanced control system compared with the former and is what this study treats. This paper reviewed the case of Newzealand and Canada where the ITQ system is introduced earlier and classified the problems by two parts for successful introduction into Korea as follows : (1) allocation method problems, (2) enforcement problems. For the first part the problems to be considered are 1) a scientific oath qouta calculation system is necessary, 2) the quota must be opened, 3) by-catch problems. 4) interactions with adjoining countries. For the second part the problems to be considered are 1) monitoring system, 2) quota transferability, 3) quota flexibility, 4) the enforcement of the system must be connected with the reduction of fishing power, 5) a mass communication and decision making system between government and fishermen is essential.

Using a trade policy, government can shift profits from foreign firms to domestic firms. This paper will reexamine how asymmetric information can affect the equivalence of tariff and quota in a duopoly, where one domestic firm competes with one foreign firm. It can happen that the domestic firm has informational advantage against the government. Within this framework, the domestic firm has private information about own marginal cost as well as the foreign firm's. The domestic firm would exploit the advantage to draw a favorable policy from the government. When the government is misled, social welfare would decline. This paper will guide how the government can extract information from the domestic firm by offering a menu of tariff or quota. Previous studies showed that quota demands information more than tariff. With the principle of revealed information, the domestic firm chooses tariff (quota) if the marginal cost of foreign firm is low (high). The quota level will be high (low) if the marginal cost of domestic firm is high (low). To prevent misrepresentation, the domestic firm should be charged when quota is implemented. When the quota level is low, the domestic firm is charged additionally. This paper can contribute to the literature of trade policy and information.

In this paper a GFC protocol based on HMR(High-speed Multimedia Ring) with a dynamic quota allocation is proposed and the performance of proposed protocol is evaluated by simulation. The HMR a medium access protocol proposed for Gbit ATM-LAN, can be applied to the GFC protocol without any modification because it uses only 4 bits for medium access of several topologies such as bus, ring and stared-bus, and priority control for satisfaction of different QoS(Quality of Service) requirements. The quota allocation method of HMR called static quota allocation has a problem of excessive access delay for the traffic with high burstness. In this paper a dynamic quota allocation method which allocates quota to the nodes according to the queue length is proposed and the performance of HMR with dynamic quota allocation is evaluated by seven simulation scenarios of CCITT. The HMR with proposed method shows better shows better access delay characteristics than the HMR with static quota allocation. Also the simulation results show that access delay performance of HMR is better than that of ATMR proposed by Japan and is similar to that of DQDB proposed by Australia.

Korean telephone surveys have been based on telephone directory and thus criticized for considerable under-coverage. Now, Korean survey institutions progress to random digit dialing (RDD) very actively. But still most surveys are administered by quota sampling, prone to assign heavier weights to social classes with more hours staying indoor. As a practical remedy, time-balanced quota sampling scheme was proposed by Huh and Hwang (2006). This study compares two telephone surveys on TV audience environment in Korea: RDD with conventional quota sampling versus RDD with time-balanced quota sampling.

This study aims to clarify background and peculiarity of teacher policy in Finland. Especially we focus on the historical changes of teacher policy, the way of decision for teacher quota and the recruitment of teacher. The following two points of the teacher policies were characterized. First, municipalities have the rights of teacher selection on their own. And the universities for teacher education have strict two phases to select the pre-teacher. The teacher quota was decided by managing the pre-teacher quota in advance. Second, universities and municipalities have a high degree of autonomy in designing their curricula and teacher policy. To date, Finnish teacher policy has not faced any problems in attracting applicants and managing quota. Some suggestions were obtained about the improvement of teacher policy in our country.

This study is to analyse the impacts of screen quota in the screen industry and suggests policy implications. To achieve the purpose of this study, we reviewed the theoretical base and history of screen quota, and analyze the share ratio of domestic films and the impacts of screen quota on the actors concerned it. The screen quota was introduced for the purpose of cultural diversity and the protection of screen industry. But it constrained consumer's choice and owner's property. This study suggested policy implications bases the analytical results.

Screen Quota is very important topic at our whole society not only film industry. Moreover the opinions are sharply divided. So, journalism, at the objective and neutral position, has the responsibility to present objective field to discuss and neutral information. This script censoriously focuses that how Korean Journalism handles Screen Quota issue from the upper mentioned premises. The first point is Korean Journalism gives legitimacy to the Governmental persistence, which is fixing Screen Quota as a hurdle for the FTA settlement so that it should be reduced. Secondly, Korean Journalism has been reducing the importance of the Screen Quota issue as the problem of film industry itself own, describing it as combat between Government and Film Industry. Third, it describes the Screen Quota as a privilege granted to the Film industry only. Finally, it provides power to the point of view of the Government which insists to reduce the Screen Quota mentioning the superiority of the competitiveness of the Koran Films discriminatingly. In conclusion, I could not but define that Korean Journalism is only speaking for America and Korean Government especially about the Screen Quota issue which is divided sharply. What it means is Korean Journalism has not been providing not only objective information but also impartial dispute field to the public for the issue which has very importance socially. The news and discussions about Screen Quota shows that this issue is not free from the progress of FTA which includes the Screen Quota problem. Further on, it could be deduced that the discussion about Korean film industry has kept on focusing its topic to the choice of decreasing or maintaining Screen Quota. The cultural contents have been expanding its importance day by day. Endeavors to settle the enormous problems of film industry should be preceded to strengthen the competitiveness and to prepare against market opening. Consequently, to solve the problems of film industry, Screen Quota should be positioned as a protect policy rather than a remedy for every ill, at the same time all the possibilities should be considered especially for the problems that Screen Quota could not solve.
