Fatigue after delivery affect women's birth experience and interrupt the process of labor. Finally woman cannot have a positive birth result and will experience a postpartum fatigue. But researches about fatigue during the labor are lacked. Nurse help adapting a mother's role, bonding with new baby, recovering after birth, and improving woman's quality of life through decreasing fatigue during the labor and intercepting a continued postpartum fatigue. So it is very important that measuring a fatigue and confirming relationships between fatigue and factors affecting fatigue. The purpose of this study was measuring the level of fatigue within 4hours after delivery and identifing factors affecting fatigue. The ultimate goal was to contribute to improving a birth experience and adapting after birth through decreasing the level of fatigue and interventions. The data was collected for this study at the hospital of two universities and the third hospital in Seoul from Aug. 15. to Nov. 10. 2000. The subjects were 106 of mothers who deliveried a normal newborn and were tested within four hours after birth. The instruments were The Visual Analogue Scale for fatigue, The State Anxiety Inventory, and The Labor Support Inventory. The data were analyzed by using percentage, mean, SD, t-test, ANOVA, Pearson correlation. The results of this study were as follows; (1) The level of fatigue during the labor was 61.48point. (2) The deferences according to general and obstetric character affecting fatigue founded that there were Significant differences according to job(t=2.659, p=0.009), and the type of delivery(t=-2.035, p=0.044). (3) The deferences according to factors affecting fatigue revealed that there was significant difference according to quality of sleep(F=2.935, p=0.037). The significant fatigue and the fatigue after delivery was anxiety(r=0.343, p=0.000). The above findings indicate that the level of fatigue during the labor is higher than during pregnancy and postpartum. Woman having a job, delivering by vacuum was more fatigued. The level of fatigue according to a quality of sleep was significant difference. The poor quality of sleep, higher level of fatigue. And the more anxiety after delivery, the more fatigue. So, the variable nursing interventions for lessening the level of fatigue through appling the situation for rest, relaxation during the labor to reserve energy, and decreasing anxiety should be provided for mothers.

본 연구의 일차적 목적은 지난 40년간 일어난 초고속 경제성장의 경험에 유념하면서 한국 여성노동력의 성격변화와 그 대응양식으로서 노동(관련)정책을 해당 정권별(박정희-전두환-노태우-김영삼-김대중)로 구분하여 살펴보는 것에 있다. 60년대 초반 산업화 도입기부터 역대 정권은 각기 다른 모습으로 여성노동력을 저임금-단순-미숙련-산업인력으로 주변화시켜 왔음을 관련자료를 통해서 확인할 수 있었다. 구체적으로 60년대 산업화 초기에는 노동집약적 산업에 저임금 산업인력으로 70년대 중화학공업 육성기예는 저임금을 특징으로 하는 전통적 여성직종에 집중배치되었다. 80년대 들어서는 의류 전자 신발 등의 업종으로부터 집단해고 또는 대량감원의 대상으로 전락하였다. IMF 경제위기 전후 90년대는 비정규진 노동의 확산과 고용불안정 혹은 실업이 한국 여성노동의 현실에 충격을 주어 여전히 그 영향력에서 벗어나지 못한 상태에 놓여있다고 하겠다. 한편 정부 측의 다양한 대응양식으로서 노동(관련) 정책이 제안되고 있으나, 불합리한 노동 현실의 근본적인 대안으로 평가되기에는 역부족이라고 말할 수 있을 것이다.

We investigate the optimal consumption and investment decision problem of an agent whose time preference is time-inconsistent. Specifically, for a time-separable utility function, the agent's subjective discount factor is supposed to be changed randomly in the future. We provide closed-form solutions in the presence of income process. The method can be extended into the case with a stochastic income process.

VLM-ST process requires an additional human interaction due to the manual stacking and bonding. Hence, building time, building cost and the part quality are dependent on the skill of labor. In this present work, a novel rapid prototyping (RP) process, as an automatic VLM-ST (VLM-STA), has been proposed to improve building efficiency of VLM-ST process and reliability of products. The apparatus of VLM-STA is designed to embody the process. Several characteristics of the proposed process and the apparatus are discussed. In order to examine the efficiency and the applicability of the proposed process, various three-dimensional shapes, such as a piston and a human head shape, are fabricated on the apparatus.

In this paper the prevailing geography of the information sector, fousing on its occupatonal dimension, is examined. The purposes of this paper are to analyze the labor force share of information occupation workers at each special city and region, to compare the inter-regional distribution of information workforce and to analyze regional share of information occupations in manufacturing industry. Spatial pattern of size and occupational composition of information sector shows a core-periphery disparity. There is a clear evidence of Seoul's dominance of the information economy, particularly such as scientific and technical, consultative services, management and process control function. Also the distribution of information workers in manufacturing industry over space was polarized than is the case for total manufacturing employment and noninformation workers. Therefore Korean information economy is marked by a highly articulated spatial division of labor within individual industry, which can be attributed to the locational characteristics of information intensive industries and industrial composition of regional economy. From the results of this study, information employment prospects among regions of Korea would reinforce the unequal geography of job opportunity. In this light, regional policy efforts should be given to the improvement of information infrastructure to facilitate new computer-based service products and process in peripheral regions.

Consumption of chicken feet has been increasing recently, thus it was necessary to produce good quality of bone less chicken feet. In the process of bone removal during chicken feet production, feeding, conveying, cutting and bone removing process takes about 90% of overall labor. Therefore, the development of a chicken feet-bone remover was necessary to reduce the cost of labor. There has been few research on the chicken feet bone removers so far in Korea as well as worldwide. So the main objective of this study was to develop a chicken feet-bone remover which is suitable for domestic circumstances. The average length of chicken feet was 113.3 mm with maximum and minimum lengths of 135.8 mm and 92.2 mm, and the average diameter of chicken leg was 12.5 mm, average width of the toe was 56.2 mm and the average weight of chicken feet was 26.4 g with maximum and minimum weight of 39.3 g and 16.9 g, respectively. Also, the average moisture content was 64.7% (w.b). The average cutting force of little toes was 15.6 N for the size ranges of less than 3.5 mm, 22.5 N, 3.5~6.0 mm and 30.3 N for larger than 6.0 mm in diameter, respectively.

본 연구는 고용보험 DB(2000~2007)를 사용하여 이직사유별로 일자리 이행 경로 및 성과를 비교하고, 미취업탈출 및 취업탈출 확률의 결정요인에 대한 회귀분석을 수행하였다. 주요 분석 결과는 다음과 같다. 비자발적 이직의 경우 자발적 이직에 비해 새로운 일자리에서 일자리 기간이 크게 감소하고 실질임금 증가율도 매우 낮다. 이러한 일자리 이행성과의 차이는 체계적인 직장탐색 부족에 따른 우수한 일자리 매칭 확보의 어려움, 노동시장에서의 부정적 신호효과, 이전 일자리에서 축적된 인적자본의 활용 가능성 저하 등 비자발적 이직의 특성을 반영하는 것으로 풀이된다. 실업급여 수급 여부는 미취업탈출 확률을 줄이는 효과를 가지지만 동시에 실업급여 수급 후 진입한 새로운 일자리에서는 취업탈출 확률을 낮추는 긍정적 효과를 가지는 것으로 나타났다.

The laboratory animal group separation is dividing animal population into subgroups, which have similar average and standard deviation values among the subgroups, based on the biological characteristics such as body weight, glucose level in blood, etc. Although group separation is very important and initial step in experimental design, it needs a labor intensive process for researchers because of making similar average and standard deviation values among the subgroups using the raw biological characteristics. To reduce the labor cost and increase the efficiency of animal grouping, we developed a web program named as laboratory animal group separation (LAGS) program. This LAGS uses biological characteristics of population, number of group, and the number of elements per each subgroup as input data. The LAGS automatically separates the population into each subgroup that has similar statistical data such as average and standard deviation values among subgroups. It also provides researchers with the extraordinary data generated in the process of grouping and the final grouping results by graphical display. Through our LAGS, researchers can validate and confirm results of laboratory animal group separation by just a few mouse clicks.
