This thesis discussed the status of women workers as wage laborers and home laborers and the valid of a documentary movie for representing women laborers through a documentary movie, Weabak that revolved around Home-ever occupation strike leaded E-Land labor union at 30th June, 2007. Jobs for women labors got covered by the flow of flexibility with the policy of labor flexibility in South Korea during 1990s. The reasons that justify this trend are their position in the households, and their roles in working places are not very important because there are not required difficult skills. The mass dismissal which caused the E-Land strike also shared these ideologies. In Weabak, since women laborers were always expected to care for their family, they were need strikes in their home as well as their working place. However, a household is a basement for them to get the identity as a women laborer. It has two ambivalent meanings, as a protected area and disorder for them to pursue their life at the same time. Identity of Women laborers, domestic laborers as well as wage laborers, are very difficult to identify as a general noun, a laborer. Weabak is an important example to show us the possibility of a documentary as searching new realism for representing women laborers' story using their own perspective.

교육인적자원부에서는 학교급식의 안전성 확보를 위하여 1999년에 특별정책 연구를 실시하여 학교급식 HACCP 일반모델을 개발 보급하고 2001년부터는 규모가 큰 학교에서 조리실이 설치된 모든 급식학교로 점진적으로 적용을 확대하였다. 그럼에도 불구하고 학교급식에서 식중독 사고는 증가 추세에 있으므로 학교급식에서의 HACCP 시스템을 재진단하고 수행도가 낮은 중점관리점의 문제점을 짚어내는 것이 필요하다. 따라서 본 연구에서는 대전지역의 초, 중, 고등학교 영양사 153명을 대상으로 위생관리 직무 수행도와 HACCP의 일부 CCP (중점관리점)수행도, HACCP에 대한 인지도, 급식시설현황 등에 대하여 조사하고 변인간의 관련성을 분석하였다. 조사 대상자는 초등학교 영양사 56.5%, 중학교 영양사 25.5%, 고등학교 영양사 17.6%이었으며 4년제 대학 졸업자가 51.0%로 가장 많았고 연령은 30-34세가 36.6%, 35-40세가 21.6%로 30대가 대부분이었다. 근무경력은 평균 5.8년이었으며 영양사 1인당 담당하는 평균 학생수는 1,163명, 조리종사원 1인당 배식 아동수는 평균 124명이었다. 배식방법은 교실배식이 56.2%, 식당배식 34.6%, 교실과 식당의 혼합형태가 9.2%로 교실배식이 차지하는 비율이 많았고 직영급식이 90.2%로 대부분을 차지하였다. 위생관리 영역의 수행도는 개인위생관리 부문이 가장 높았고 기기설비 위생관리, 저장관리, 교차오염관리, 시간관리, 온도관리 순으로 나타났으며, 특히 온도관리 수행도는 낮은 것으로 나타났다. 식당배식을 실시하는 학교의 온도관리 수행도가 다른 그룹에 비해 높았고 직영급식의 시간관리수행도가 위탁급식 보다 높았다. 영양사의 연령과 근무경력이 증가할수록 모든 위생관리영역에서 수행도가 높아지는 경향을 보였다. CCP별 수행정도 평가에서는 ‘운반 및 배식과정(CCP7)’이 가장 높은 수행도를 나타냈고 그 다음으로는 ‘검수’, ‘식품취급 및 조리과정’, ‘식품접촉 표면 세척 및 소독과정’, ‘식단의 구성’, ‘생채소 및 과일의 소독’, ‘잠재적으로 위험한 식단의 관리’ 순으로 나타났다. ‘운반 및 배식과정의 수행도’는 식당배식이 유의적으로 높은 점수를 보였고 CCP8(식품접촉표면의 세척 및 소독)를 제외한 모든 영역에서 직영급식이 위탁급식에 비해 높은 유의성을 나타내었다. 또한 근무경력과 연령이 많을수록 모든 CCP영역에서 높은 수행도를 보였다. CCP1과 CCP2의 수행도가 낮은 주된 이유로 ‘CCP1과 CCP2의 관리기준이 이해하기 어렵다’이었다. 학교 급식관리 영양사의 HACCP시스템에 대한 지식 및 이해 정도를 조사한 결과 HACCP 인지도 점수의 평균은 총 100점 만점에 전체 평균 점수는 74.9점이었다 CCP별 점수분포는 CCP7의 인지도 점수가 가장 높았고 CCP6, CCP1, CCP5, CCP3, CCP8, CCP2의 순으로 절차 낮아졌다. 정규직의 HACCP인지도 점수가 위탁직 보다 높았으며 근무경력에서도 경력이 3년 미만인 경우가 가장 낮고 8년 이상인 경우가 가장 높은 점수를 보였다. 급식시설면은 보온보냉시설을 갖춘 학교가 온도관리 부문에서 갖추지 않은 학교보다 높은 수행도를 나타냈고, 전처리실과 손 소독기가 있는 학교는 교차오염관리 부문에서 높은 수행도를 보였다.

VE aims at reduction in a budget, improvement of function, structural safety and quality security for public construction projects. However, there is possibility for the structural safety and quality security review to be insufficient because related regulations are mostly composed of analysis on economic efficiency of design. In addition, due to the misconception about VE as a cost saving methodology, an alternative is being presented which still focuses mainly on cost saving, but with no objective evaluation of function related to cost. In order to improve this, the government adopted the reduction of life cycle cost and proposal of value improvement, and let people specify the cost and function of the original plan versus the alternative plan, and the value changes between them. However, it is written mainly into practical convenience rather than theoretical basis since a specific way is not suggested. The current method sets a different starting point by applying the attributional difference of function and cost. Furthermore, an evaluation standard for correlating is an important element in rational decision making for assessing and choosing an alternative. This paper analyzes the process and method of function & cost scoring when performing VE and suggests a mathematical normalization model in order to support rational decision making when selecting an optimum plan.

Since Diffusion tensor from Diffusion Tensor Magnetic Resonance Imaging(DT-MRI) is so sensitive to noise, the principle eigenvector(PEV) calculated from Diffusion tensor could be erroneous. Tractography obtained from PEV could be deviated from the real fiber tract. Therefore regularization process is needed to eliminate noise. In this paper, to reduce noise in DT-MRI measurements, the Dyadic Sorting(DS) method as regularization of the eigenvalue and the eigenvector is applied in the tractography. To resort the eigenvalues and the eignevectors, the DS method uses the intervoxel overlap function which can measure the overlap between eigenvalue-eigenvector pairs in the $3\times3$ pixel. In this paper, we applied the DS method to the three-dimensional volume. We discuss the error analysis and numerical study to the synthetic and the experimental data. As a result, we have shown that the DS method is more efficient than the median filtering methods as much as 79.97%~83.64%, 85.62%~87.76% in AAE, AFA respectively for the corticospinal tract of the experimental data.

In this paper, we proposed a watermarking algorithm by using difference matrix between successive blocks in the transform domain. In the preprocessing, original image is decomposed with 1-level sub-bands by DWT. Then, all sub-bands which are excepted the low-frequency bands are set to normalize and make a reference image after transforming inverse DWT. The statistic variance of successive blocks between the original image and the reference image are calculated and finally, watermark is embedded considering the local characteristic with respect to the high-frequence components. Experimental results showed that the proposed approach is robust and better invisible in such attacks as filtering, JPEG and noise addition.

The purpose of this study is to propose the human resource management strategies of non-standard workers that can contribute to accomplishing both corporate social responsibility and business purpose in efficient and effective ways. For the purpose, this researcher investigated circumstances under which Korean companies are using non-standard workers and systems related to those workers. In Korea, the Non-Standard Workers Protection Act was enacted and revised, and became effective on July 1, 2007. The main provisions of the act are as follows. First, the systems of discriminatory treatment prohibition was legally stipulated, Second, restrictions on overwork for fixed-term and part-time employees and the written statement of working conditions were compelled. Third, only 26 kinds of jobs were permitted for worker dispatch in accordance with positive list system. To achieve their business purpose, companies often use standard workers, but sometimes non-standard workers unavoidably in accordance with their business strategy. This study propose main human resource management strategies of non-standard workers such as determining the scope of jobs, strengthening legal and systematic human resource management, improving human relations, extending the grievance procedure and converting non-standard workers into standard ones.

This paper examines what determines the use of contingent workers in Korean Department Stores. Drawing on internal labor market, transaction cost & agency, and bureaucracy theories, I hypothesize that four factors affect the use of contingent workers: job characteristics, HRM, occupation, and organizational characteristics. Data from a sample of employers surveyed by the author in 1997 were used to test the hypotheses, and analyses showed the following results. First, consistent with job-based perspective, we find that such job characteristics as firm-specific skill and the level of skill significantly affect the use of contingent workers. But job standardization and outcome measurability have no effects of its use. Second, also we find significant effects on the use of contingent workers of such HRM as scrutiny on employee selection and promotion system. The promotion system has expected effect on its use, but scrutiny on employee selection has opposite effect. Third, we find that occupation significantly affects the use of contingent workers, especially the extent of use of contingent workers of sales service is as five hundred times as that of managerial occupation. Fourth, also consistent with organizational-based perspective, we find that the firm's size significantly has positive effects, and affiliate company and labor union have negative effects. That is, the larger firm's size is, the more possibility of use of contingent workers exists, and the possibilities of its use reduce in case of affiliate company and in front of labor union. Finally, we discuss the implications and limits of theses findings.

In this study, a series of FEM numerical analyses was conducted to compare the resistance performance of concrete drainage protection facility to blast vibration. Two different types of ㅁ-shaped protection facility, which are suggested in the study, were compared to the traditional ㄷ-shaped one. In the analyses, the vibration resistances of the three protection facilities were evaluated under the varying conditions of the standoff distance from the explosion and charge weight per delay. As a result, it was found that the two proposed types of drainage protection facilities are superior to the traditional one in the vibration reduction performance.
