PPC(Percent Plan Complete)는 계획 작업량 대비 수행 작업량을 의미하며 PPC 측정을 통해 협력업체의 계획 신뢰도를 향상시키며 프로젝트 관리자의 공정계획 능력을 향상시킴으로써 후속 공정의 생산성 향상과 자재 절감 및 시간 버퍼의 단축이 가능하다. 기존 성과지표인 공기, 비용은 실제 문제가 발생하는 작업을 판단하는 데 오류가 발생하나 PPC는 실제 문제가 있는 작업을 말해주므로 측정 결과에 따라 즉각적인 대책수립이 가능하다. 이러한 PPC는 측정과정이 간단하여 현장 적용성이 매우 높다. 때문에 최근 PPC를 측정하여 작업의 성과를 측정하는 사례가 증가하고 그 유용성은 검증되었지만, 작업을 수행한 내력에는 차이가 있음에도 불구하고 기존 PPC 평가는 단순히 추이 분석 또는 평균치와의 비교로 작업을 분석 평가 하고 있다. 따라서 본 연구에서는 측정된 PPC를 중앙경향치 평가뿐만 아니라 변이를 고려하여 PPC를 평가하는 절차 및 평가차트를 제안하고자 한다.

Mass customization (MC) is a business practice that aims to provide customers with customized products and services at near mass production efficiency. To achieve the aim, a number of methods to implementing MC are proposed. However, most of them require changes in entire process of the company, which make companies hesitate to implement MC even if it is essential to survive. In this paper, we proposed alternatives to partially implement MC for quick adaptation of MC. The base line assumption is not to change the production lines. The pros and cons of alternatives are given by qualitative and quantitative evaluation. Especially, by giving radar chart analysis of the quantitative measures, we give insight on the changes in the business performance measures, such as time to market and cost. Proposed alternatives are based on sub-processes such as purchasing raw materials, production process changes and packaging for efficient logistics. In this way, companies are able to provide customized products with small changing of the current manufacturing system. The process and benefit of the proposed strategy is verified by real world cases of a Korean health food company.

The purpose of this study is to develop an excellent bodice prototype that is adapted to the body shape of middle-aged women using 3D measurement data. In the evaluation of appearance, S pattern 4.00, B pattern 2.80, E pattern 2.40, L pattern 1.40 were shown in order, and the best fit of S pattern was evaluated as excellent. As a result of looking at the color distribution chart to find out the amount, E pattern and S pattern were not space in the front bust, armhole, and the back waist line. The B pattern and the L pattern were marked in blue because of insufficiency space in the back neck. As a result of evaluation the amount of air gap in the clothing, the air gap of the bust was 0.12, which is the largest pattern of B. Next, the L pattern appears as a tight circle with smallest air gap in the order of the S pattern 0.096, the E pattern 0.08, and the L pattern 0.003. The S pattern was evaluated to be the most appropriate for the body shape of middle-aged women. But the waist and back were slightly tight. Middle-aged women have larger shoulder-related items and larger waist circumference. Therefore, when you set the perimeter item, you should add 1-2cm of space amount and give extra space to the circumference area.

석재는 주로 장식용 및 조각용으로 사용되며 따라서 우수한 물성도 골고루 지녀야 한다. 다양한 물성 중에서 공극계수가 석재의 유용성을 지배하므로 공극의 성질과 연관하여 석재의 품질구분 설정을 시도하였다. 이 연구에서는 화강암질암류 및 화강암질편마암의 심도별 시추코아 시료가 사용되었다. 공극률과 흡수율의 상관도에서 문경 화강암질편마암($Gn_1$)의 측정치 범위가 가장 넓은 분포상을 보이며, 포천화강암($Gr_2$), 문경화강암($Gr_1$)의 순으로 그 범위는 감소한다. 각 암체의 강도는 변질도에 따라 변화한다. 또한 압축강도와 인장강도와의 상관성에서도 측정치의 범위는 $Gn_1$, $Gr_2$ 그리고 $Gr_1$의 순으로 감소한다. 석재의 품질구분 설정에 있어 공극률이 대표적인 물성으로 채택되어 여러 물성에 대한 상대적인 평가가 이루어졌다. 공극률(n)-비중(G), 흡수율(Ab), 압축강도(${\sigma}_c$), 인장강도(${\sigma}_t$), 쇼아경도(Hs) 그리고 탄성계수($E_{t}$)와의 상관도에서 각 등급별 기준이 설정된다.

It has been increasingly difficult to predict the amounts of Acer mono sap to be collected due to droughts and cold waves caused by recent climate changes with few studies conducted on the prediction of its collection volume. This study thus set out to propose a Big Data prediction system based on meteorological information for the collection of Acer mono sap. The proposed system would analyze collected data and provide managers with a statistical chart of prediction values regarding climate factors to affect the amounts of Acer mono sap to be collected, thus enabling efficient work. It was designed based on Hadoop for data collection, treatment and analysis. The study also analyzed and proposed an optimal prediction model for climate conditions to influence the volume of Acer mono sap to be collected by applying a multiple regression analysis model based on Hadoop and Mahout.

In order to evaluate landslide susceptibility in Yanbian region, this study analyzed 7 factors related to landslide occurrence, such as soil, geology, land use, slope, slope aspect, fault and river by Analytic Hierarchy Process (AHP), and calculated the weights of these 7 hazard-induced factors, determined the internal weights and the relative weights between various factors. According to these weights, combining the Remote Sensing technology (RS) with Geographic Information System technology (GIS), the selected area was evaluated by using GIS raster data analysis function, then landslide susceptibility chart was mapped out. The comprehensive analysis of AHP and GIS showed that there has unstable area with the potential risk of sliding in the research area. The result of landslide susceptibility agrees well with the historical landslides, which proves the accuracy of adopted methods and hazard-induced factors.

The intent of this study is to propose a method for appraisal of the indoor thermal environment of apartment housing by measuring physical factors and residents' response to questionnaire survey. The experiments were performed on eight houses each in summer (August 18 through 31,1995) and winer (february 16 through 20,1996). It included measurements of indoor air temperature, globe temperature, relative humidity, and CO2 concentration. The questionnaire surveys were performed each in summer (July 16 through 20, 1996) and winer (February 13 through 16, 1996). And 248 cases in summer and 297 cases in winter were used in analysis. These questionnaire surveys asked residents' response about thermal sensation, humidity sensation, sense of air freshness regarding the indoor thermal environment. data acquired through the experiments and questionnaire surveys were then transferred to scales that allowed relative comparison, and measured to an appraisal standard chart. Appraisal tools included appraisal charts and radar charts. Indoor thermal environment was judged to be positive according to experiments, but residents appraised the thermal environment to be average. This difference between the two can be found in the strict standards by which residents judge the thermal environment of their apartments.
