기존의 상업적인 3D CG 애니메이션 제작 공정 구조는 부서간의 병목현상으로 모든 부서가 동시에 작업을 할 수 있는 효율적인 구조로 이루어지지 않고 있다. 예를 들어, 애니메이팅 작업을 하기 위해선 선행되어야 할 모델링과 Set-Up 단계가 끝나기 전에는 애니메이팅 작업을 할 수가 없다. 그 결과, 제작 일정의 지연, 제작비의 손실을 발생시키게 되고, 또한 선행된 작업에 수정을 가할 경우 수정이 끝날 때 까지 애니메이팅 작업은 중단된다는 결과를 야기 시킨다. 이런 문제는 표준으로 정해 놓은 "마스터 캐릭터"의 적용으로 도움을 줄 수가 있는데, 프로젝트의 시작과 동시에 모델링과 set-up 그리고 다른 어떤 작업과도 독립적으로 애니메이팅 작업을 시작 할 수 있고 수정 작업도 독립적으로 수행이 가능해서 애니메이션 제작공정을 효율적으로 관리할 수 있다.

In this study, I analyzed how wives experience their husbands' sudden loss of jobs. In-depth interviews were conducted with six married women whose husbands lost jobs. Each person was interviewed for 3 to 4 hours, between June and August 2003. The wives tended to see the husband as someone who gave them a hard time, yet whom they still had to rely on. In addition, the husband was another difficult problem that they had to deal with, because they had to watch the husband struggle to adjust following the distressing event. Some wives blamed themselves for the unemployment of their husbands and were pained for their husbands' adversity. The wives also had the challenge of taking up a job to support the family. Their marital life became tougher and more conflicts emerged. The wives often alienated their husbands from the rest of the family unintentionally, or attempted to break away from their husbands by leaving home. Yet, they returned home in the end, and tried to find hope, by taking a different perspective and looking at the bright side of life, by finding the value of her existence, through faith, and by reaffirming love for the husband and children.

There are few studies on the characteristics of debtors in individual rehabilitation procedures, though research in this field is needed. The scarcity of research means that public policy and perception are being made with inadequate information and, to a certain extent, based on personal prejudices and misconceptions. The purpose of this study was to find out demographic, economic and psychological characteristics of debtors in individual rehabilitation procedures. For this study, an in-depth interview was used. The major findings were as follows : The focus of this study is debtors in individual rehabilitation procedures. They were all under 40 and received relatively high educations. Interestingly, they showed a high tendency to use debt and an inability to manage their money. They had short time horizons and imperfect self-control in consumption and borrowing decisions. Monthly income, expenditures, asset and debt of the debtors, and monthly payment to creditors were reported. There were a lot of reasons for their bankruptcy : business failure, job loss, the cost of raising children, and expenditures for entertainment causing them to file for individual rehabilitation procedures. One of the major conclusions of this study was the discovery that their psychological characteristics were nearly the same. The implications of the study suggest that financial education and counseling must consider psychological characteristics.

이 연구에서는 고연령층이 경험하는 은퇴과정의 다양성과 긴장 정도를 파악하고 있다. 은퇴 과정의 다양성을 규정 짓는 주요 요인으로서 중장년기의 종사상 지위에 초점을 둔다. 비정규직 종사자의 취업 불안정과 빈곤 위기는 취업시점에서뿐 아니라, 이후의 노동이동 과정과 고연령기 은퇴에 이르기까지 장기적으로 그 영향을 미칠 것으로 가정한다. 1998년과 1999년 한국노동 연구원에서 실시한 1~2차 한국노동패널 조사를 이용하여 중장년기에서 고연령기에 이르기까지의 노동이동 및 은퇴 과정을 유형화하고, 주요 유형별 소득수준을 비교하고 있다.

Until now, the transmission of data for VOD(Video on Demenad) was based on a real time modelling of video data. Markow Modulated Fluid Sources(MMFS) and Markow Modulated Poisson Sources(MMPS) are the most widely used modelling methods. But the charactersitics of the VBR(Variable Bit Rate) signal prevents modelling from actually being "real-time". Also these methods call for the use of large buffers for the abolishment of cell loss. These modelling methods are, of course, useful i case of teleconferences where a real time modelling of video traffic is inevitable, but they are insufficient in cases where the characteristic infomation of video traffic can be obtained beforehand-cases such as VOD. Video data is speial in that if one file is preprocessed all other products can simply be copied from that onepreprocessed file. This characteristic helps reduce the overhead arising from the job of drawing out characteristic information to almost zero. But still, compared to the existing real time modelling method data transmission using characteristic information succeeds in raising the efficiency of data transmission. In tis paper we will outline a method of dta transmission which use the characteristic information of each video stream, and evaluate this method through some experiments.periments.

Recently, the importance of big data has been emphasized with the development of smartphone, web/SNS. As a result, MapReduce, which can efficiently process big data, is receiving worldwide attention because of its excellent scalability and stability. Since big data has a large amount, fast creation speed, and various properties, it is more efficient to process big data summary information than big data itself. Wavelet histogram, which is a typical data summary information generation technique, can generate optimal data summary information that does not cause loss of information of original data. Therefore, a system applying a wavelet histogram generation technique based on MapReduce has been actively studied. However, existing research has a disadvantage in that the generation speed is slow because the wavelet histogram is generated through one or more MapReduce Jobs. And there is a high possibility that the error of the data restored by the wavelet histogram becomes large. However, since the wavelet histogram generation system based on the MapReduce developed in this paper generates the wavelet histogram through one MapReduce Job, the generation speed can be greatly increased. In addition, since the wavelet histogram is generated by adjusting the error boundary specified by the user, the error of the restored data can be adjusted from the wavelet histogram. Finally, we verified the efficiency of the wavelet histogram generation system developed in this paper through performance evaluation.

Models of upward flame spread have been attempted in the past, but in the current work an emphasis has been placed on developing a practical model that will be useful across a broad range of materials. Some of the important aspects of the model we: the addition of external radiation to simulate a wall that is a part of an enclosure fire and has flaming walls radiating to it, the use of a correlation for flame heat feedback distribution to the sample surface based on data available in the literature, and the use of an experimentally measured mass loss rate for the sample material, In this paper, the development of the numerical model is presented along with predictions of flame spread for three materials: hardboard, a relatively homogeneous wood-based material; plywood, which is made of laminated wood bonded by adhesives; and a composite material made of fiberglass matrix embedded in epoxy. Predictions are compared with measured data at several levels of external radiation for each material. For the materials tested, the model correctly predicts trends and does a reasonable job predicting flame heights. The need for thermal property data for practical materials, which would be appropriate for flame spread models, is indicated by this work.

Background: Noise-induced hearing loss is a well-known occupational disease that affects many fish harvesters from many fisheries worldwide, whose risk factor is prolonged exposure to hazardous noise levels. To date, academic research activities and regulatory bodies have not provided any comparative analysis among the existing methods to assess noise exposure levels of fish harvesters. This paper provides a comparison of four relevant assessment methods of noise exposure, examining the results of a measurement campaign performed onboard small fishing vessels from Newfoundland and Labrador. Methods: We traveled onboard 11 vessels engaged in multiple fisheries from Newfoundland and Labrador and performed extensive noise exposure surveys using the simplified International Maritime Organization method, the full-day measurement method, and the two methods provided by ISO 9612:2009, the task-based method and job-based method (JBM). Results: The results showed that the four methods yield similar values when the noise components are dominated by the engine and auxiliaries (steady-state sources); when noise components are dominated by the fishing gear, task-based method and the simplified International Maritime Organization method estimates are less accurate than JBM, using full-day measurements as baseline. Conclusion: The JBM better assesses noise exposure in small-scale fisheries, where noise exposure has significant variance and uncertainties on the exposure levels are higher.

Construction is one of the most dangerous job sectors, which reports tens of thousands of time-loss injuries and deaths every year. These disasters incur delays and additional costs to the projects. The safety management needs to be on the top primary tasks throughout the construction to avoid fatal accidents and to foster safe working environments. One of the safety regulations that are frequently violated is the wearing of personal protection equipment (PPE). In order to facilitate monitoring of the compliance of the PPE wearing regulations, this paper proposes a vision based method that automatically identifies whether workers wear hard hats and safety vests. The method involves three modules - human body detection, identification of safety vest wearing, and hard hat detection. First, human bodies are detected in the video frames captured by real-time on-site construction cameras. The detected human bodies are classified into with/without wearing safety vests based on the color features of their upper parts. Finally, hard hats are detected on the nearby regions of the detected human bodies and the locations of the detected hard hats and human bodies are correlated to reveal their corresponding matches. In this way, the proposed method provides any appearance of the workers without wearing hard hats or safety vests. The method has been tested on onsite videos and the results signify its potential to facilitate site safety monitoring.
