Recently, there have been active researches about the VPCS (Virtual Parallel Computing System) based on multiple agents. The PVCS uses personal computers or workstations that are dispersed all over the internet, rather than a high-cost supercomputer, to solve complex problems that require a huge number of calculations. It can be made up with either homogeneous or heterogeneous computers, depending on resources available on the internet. In this paper, we propose a new method in order to distribute worker agents and work packages efficiently on the VPCS based on the IBM Aglets. The previous methods use mainly the master-slave pattern for distributing worker agents and work packages. However, in these methods the workload increases dramatically at the central master as the number of agents increases. As a solution to this problem, our method appoints worker agents to distribute worker agents and workload packages. The proposed method is evaluated in several ways on the VPCS, and its results are improved to be worthy of close attention as compared with the previous ones.

It is a necessity to localize various elements when one tries to introduce any games developed from foreign cultures and languages. This whole process is called "localization (l10n)" which inevitably includes translation tasks. In this process, one should convert multiple unique elements into the required cultural and linguistic environments. This paper provides actual localization cases of "puns" appear in an adventure game, which is especially difficult; also it presents several typical types of translations for the puns that professional translators try. By this observation, this paper discusses some characteristics of game, as a medium, which are different from those of traditional media and proper approaches to translate "puns."

다수의 사용자가 동시에 가상머신을 사용하는 클라우드 환경은 자원 사용량을 예측하기 힘들기 때문에 사용자의 자원 요구량과 성능을 만족시키기 위해 지속적으로 마이그레이션, 오토스케일링과 같은 가상머신 관리 작업을 수행한다. 가상머신 관리 시 참조되는 가장 중요한 정보는 가상머신과 물리머신의 자원 모니터링 정보이다. 클라우드 센터에서 자원 모니터링 작업은 가상머신 관리 시 필수적이지만 모니터링 정보 수집 시 사용하는 자원은 물리머신의 자원을 사용하기 때문에 모니터링 주기가 짧으면 모니터링 작업을 위한 자원 사용으로 인해 가상머신과 자원 경쟁이 발생할 수 있다. 본 논문에서는 물리머신에서 실행 중인 가상머신의 작업의 유형에 따른 최적의 모니터링 주기를 도출하기 위해 자원 모니터링 주기가 가상머신의 성능에 미치는 영향을 분석하고 모니터링 작업으로 인해 발생하는 가상머신의 성능 저하를 최소화 할 수 있는 최적의 모니터링 주기를 도출한다.

In this study, we research for characteristics of exportation of Korean TV dramas during 10 years. During this decade, media environment has been changed significantly : platforms have been increased and viewing attitude have been also changed. We will find out these changes in TV exportation : types of TV rights, price per countries, frequency of trade per countries, etc. For this, export records of 2 Korean TV stations from 2005 to 2014 have been obtained. As a result, export countries have been diversed, price have been increased and types of TV rights also have been various.

This study proposed a field-applicable natural regeneration method using natural seeding to afforest a secondary growth forest after felling in Larix kaempferi plantations. In 2016, an experimental site was established usingseed-tree and clear-cutting methods in Gapyeong, Gyeonggi-do, South Korea. Characteristics of seed fructification and inflow in the natural regeneration site were analyzed along with an experimental site in Bonghwa, Gyeongsangbuk-do, which was established in 2014. As a result, the number of seeds per individual tree of V age class L. kaempferi was 690,340 seeds in a good year, with an estimated 13.8 million seeds per ha fruited in natural regeneration sites of L. kaempferi with 25 seed-trees per ha. Seed dispersal began in September and germination rates of seeds dispersed until November were greater than 40%. Reserved seed-tree sites showed the highest amount of seed inflow, followed by the seed-tree site and clear-cut site in descending order. The reserved seed-tree method performed better than other methods for evenly scattering seeds. Therefore, the timing of logging and seedbed generation for natural regeneration of L. kaempferi is estimated to be most effective before September when seeds are purposefully scattered using the reserved seed-tree method as an effective method for uniform seed supply.

The purpose of this study is to analyze the effect to financial outcome and workers' outcome, using the manufacturing industry database of Human Capital corporate Panel from Korea Research Institute for Vocational Education & Training. Especially, this study used the typology of Lean production and Autonomous team production, that are the typical form of alternative work organization, to analyze. In the case of domestic manufacturing industry, individual participation practices, that have the main characteristics such as QC or suggestion system, is expanded. Therefore, with the reference of Lean production, Autonomous Team Production and the Taylor system are compared and analyzed, considering the characteristics of Socio-technical System. As a result, it is showed that the Lean production and Autonomous Team Production as a alternative work organization are more positive about the organizational performance and workers' outcome than the taylor system. However, when Lean production and Autonomous Team Production are compared, it is showed unsignificant distinction to the effect of organizational performance. Meanwhile, Lean production showed more negative effect on the every dependent variables such as working hours, income, job satisfaction, and organizational commitment as workers' performance than the Autonomous Team Production. Although the common ideas and belief is that the Lean Production is superior for the quality and organizational performance improvement, it is implied the possibility that there is some damaged workers' performance on the hidden side of that mechanism.

본 논문은 2D 실사 기반 가상 헤어스타일의 자연스런 착용감을 제공하기 위한 것으로, 가상 헤어스타일러의 모발 블렌딩 방법에 관한 것이다. 제안된 방법을 2D 실사 영상에서 추출한 헤어스타일을 임의의 인물 영상의 두상에 정렬시킨 상타에서 원래의 헤어스타일에서 추출한 헤어스타일로 변해가는 반자동 필드 모핑을 수행할 시에 머리모양의 변형을 따라 단계적으로 변하는 가변 모핑 마스크를 사용하여 가상 헤어스타일을 생성하고 이렇게 생성된 헤어스타일을 가변 모핑 마스크의 경계 영역에서 시그모이드 함수에 기반한 모발 블렌딩을 수행함으로써 이중 노출 현상이 제거됨과 동시에 자연스러운 착용감을 제공하는 여러 유형의 헤어스타일을 자동으로 생성할 수 있다. 통상 이러한 작업은 사용자의 수작업에 전적으로 의존하는 반면에 제안된 방법은 반자동 필드 모핑에 기반한 편리한 사용자 인터페이스를 제공할 수 있기 때문에 반자동화를 통해 작업 피로도와 작업 시간을 경감시킬 수 있고 비숙련자도 간단한 사용자 입력을 통해 이중 노출 현상이 제거됨과 동시에 자연스런 착용감을 제공하는 가상 헤어스타일을 생성할 수 있는 이점이 있다.

This study is a subjective study on consumer's perception of drive-through as part of one method of service business to drive the drive-through service to understand how the user's perspective is more effective than the company's management position. In order to analyze the consumer's subjective viewpoint on the use of through companies, an exploratory study was conducted by selecting the Q-methodology. To this end, the analysis work was conducted in a way that the respondents classified the statement cards, and the Q population was selected and composed. Through this, the P-sample was selected and the Q-sort obtained through the classification process was used for the PC QUANL program. Was analyzed through Q factor analysis. customers divide into 3 types. Firstly, type 1 (N=14) is the people who pursue the convenience on value for time. Secondly, type 2 customers (N=4) prefer efficiency on value for time. finally, type 3 ones (N=2) put a great value on quickness. Each subjective opinion detected through this analysis will be the basis for various studies in the future, and may be used as a reference in the future direction of establishing drive-through marketing and improving the lacking parts.
