Performance based design(PBD) is the method to make a fire safety design against them after predicting the factors of fire risk in a building. Therefore, predicting fire risk in a building is very important process in PBD. For predicting fire risk of a building, an engineer of PBD must consider various factors such as ignition location, ignition point, ignition source, first ignited item, second ignited item, flash over, the state of door and fire suppression system. But, it is difficult to trust fire safety capacity of the design because the process in Korea' PBD is unprofessional and unreasonable. This paper had surveyed some cases of PBD that had been made in Korea to find the problems of the process to predict fire risk. And it have proposed the improvements of process to predict fire risk of a building.

An estimation of indices for potential process capability (Cpk) and/or overall process performance (Ppk) is considered in order to gain insight into the statistical process control. The similarity and the difference of the two indices are discussed in some detail to clarify the meaning and usage of the two indices. It is demonstrated that the short term variance can be estimated within the framework of analysis of variance (ANOVA). Theoretic background is examined and followed by a simple numerical example, with a view to the implementation of the concept in the industrial fields.

The goal of this study is optimization of transparency liquid chemical coating process. At coating process in the maintenance of the coating gap is an important factor. Specially, at a small split from the substrate using the existing methods is difficult to maintain the uniformity of coating. In this study, slit coating uniformity and compare inkjet uniformity and thickness profile was analyzed using alpha-step. Also, the pencil hardness test and the color difference measurement were performed. As a result, changes of the coating process need to be made depending on the type of substrate and inkjet coating was suitable for substrate of a small split.

The purpose of this study is to introduce the limit of previously used six sigma quality process evaluation metrics, Zst and Ppk, and a solution to overcome this drawback by using a metric based on performance evaluation of Z-factor quality innovation. Case analysis on projects from national six sigma contest from 2011 to 2012 is performed and literature review on new drug development HTS (High Throughput Screening) is used to propose innovative performance evaluation metrics. This research shows that experimental study on six sigma evaluation metric, Zst and Ppk, have no significance difference between industrial type (Manufacturing, Semi-Public Institute, Public Institute) and CTQ type (Product Technology Type CTQ, Process Technology Type CTQ). Following discovery characterize this quality improvement as fixed target type project. As newly developed moving target type of quality innovation performance metric Z-Factor is used for evaluating experimental study, hypothetical analysis suggests that Zst and Ppk share different relationship or even show reciprocal relationship. Constraints of the study are relatively small sample size of only 37 projects from past 2 years and conflict on having interview and communication with six sigma quality practitioner for qualitative experimental study. Both moving target type six sigma innovation project and fixed target type improvement project or quality circle enables efficient ways for a better understanding and quality practitioner use by applying quality innovation performance metric. Downside of fixed target type quality performance evaluation metric, Zst and Ppk, is presented through experimental study. In contrast, advantage of this study is that high throughput requiring product technology, process technology and quantum leap typed innovation effect is evaluated based on precision and accuracy and Z-Factor that enables relative comparison between enterprises is proposed and implemented.

It seems most important for a manufacturing company to be well aware of its relationship with suppliers. This is why it is essential to analyze and control the structural relationship among CEO's characteristics, relations between suppliers and manufacturers and new product development performances affected by such relations. The present study may be summed up as follows: First, from the analysis of characteristics of manufacturing company's CEO and relations between suppliers and manufacturers, it could be verified that CEO's characteristics exercised influence upon sharing of product development process and upon cooperation for technical manpower, but not upon sharing of core technologies, signifying the fact that nothing could be more important than the role of CEO who has strong will to improve his or her relations with suppliers; and Second, from the analysis of relations between suppliers and manufacturers as well as relations between management and new product development performances, it became evident that both management performance and product development performance were affected by sharing of product development process. It was also known that cooperation for technical development process had influence upon the product development performance but not upon the management performance. Furthermore, the analysis showed that both management performance as well as product development performance were affected by sharing of core technologies.

In this paper, we raised the performance of heuristic algorithm to assign job to workers in parallel line inspection process without sequence. In previous research, we developed the heuristic algorithm. But the heuristic algorithm can't find optimal solution perfectly. In order to solve this problem, we proposed new method to make initial solution called FN(First Next) method and combined the new FN method and old FE method using previous heuristic algorithm. Experiments of assigning job are performed to evaluate performance of this FE+FN heuristic algorithm. The result shows that the FE+FN heuristic algorithm can find the optimal solution to assign job to workers evenly in many type of cases. Especially, in case there are optimal solutions, this heuristic algorithm can find the optimal solution perfectly.

This paper presented experimental results for circulation type UV-TiO₂ photocatalytic oxidation process. We have developed UV-TiO₂ photocatalytic oxidation process with activated carbon to control odor and VOCs in indoor and industrial applications. In this study, common indoor air pollutants, namely ammonia, formaldehyde, hydrogen disulfide, toluene were selected to investigate their efficiencies for UV-TiO₂ photocatalytic oxidation. In high concentration test, the decomposition efficiency was high in order as ammonia, toluene, formaldehyde, hydrogen disulfide. Three type of individual processes are tested for ability to increase decomposition efficiency. UV-TiO₂ photocatalytic oxidation combined process with activated carbon was excellent among the three type processes without reference to gas species. It was considered that this circulation type process will overcome short retention time for treatment for UV-TiO₂ photocatalytic oxidation. It will promise that this circulation type UV-TiO₂ photocatalytic oxidation combined process can apply indoor and industrial applications to remove odor and VOCs quickly.

And a developer is required to the technical development that aim performance is cleared. The study selected a detailed item about performance item of re-modeling element technique through the requirement which the nations (such as America, England, Japan, etc) and the agencies of foreign countries present and item selection standard, from the point of view where the interest not only the individual but also govemmental politic viewpoint is coming to be higher re-modelling than new construction.

본 연구는 압연공정을 이용하여 금속망 만을 사용하여 금속막을 제조하는 과정과 금속망과 금속분말을 사용하여 금속막을 제조하는 과정에 대해 연구했다. 금속망 압연과정에서 선택된 금속망은 각각 10%, 20% 그리고 30%의 감소율로 압연했다. 이 압연공정은 망 wire의 지름을 변화시키거나 망의 단면적의 감소를 통해 망의 공경 크기를 감소시킨다. 압연된 금속망의 여과율은 압연시키지 않은 금속망의 여과율과 거의 동일한 여과율을 보였으며 금속막의 공경크기 분포 또한 더 균일했다. 금속망 위에 금속분말 층을 제조하는데 있어 분말 접합제로서 PVA를 사용하였으며 1시간 동안 100℃에서 금속분말 층을 건조시키고 진공에서 3시간 동안 1000℃에서 소결시키는 방법이 높은 공경 밀도와 균열이 없는 금속망 위에 금속분말 층을 형성하는 최적 조건이었다. 소결 전 30%감소율을 가지는 금속망에 대해 금속분말 층 형성에 압연공정을 적용할 경우 여과율이 약 0.7 μm인 금속막이 성공적으로 제조되었다.

To improve water quality of Buji Stream and Shenzhen River, the Bujihe Wastewater Treatment Plant has been reconstructed from the original coagulkation-flocculation sedimentation system into the enhanced hybrid submerged biofilm-activated sludge (EHYBFAS)system developed by the authors. The main design parameters of the EHYBFAS system, process characteristics, operational performance, techno-economic index, and experience in design, construction and operation are described，which set up an example of the municipal wastewater treatment plants using the novel process of EHYBFAS, which has lots of advantages, such as stable and high operational performance with the final effluent quality well meeting 1A-1B standard of GB 18918-2002( Chinese national standard for pollutants of effluent from the MWWTPs), much less footprint of 1ha/(100×103m3/d)) vs 4-5ha/(100×103m3/d), much lower capital and operation costs of 700-800 Yuan(RMB)/(m3/d) and 0.5 Yuan(RMB)/m3 vs 1200-1500 Yuan/(m3/d)and 1.0-1.2 Yuan/m3 and much less sludge production of 0.3g dry solid/g removed BOD5 vs 0.7 g dry solid/removed BOD5 respectively for the MWWTP with AS process.

In this study, copper vapor chambers with built-in cooling fins, which eliminated the soldered or brazed joints in the conventional vapor chamber, were fabricated using the metal injection molding process. The results show that with optimized molding parameters, fins with an aspect ratio up to 18 could be produced. After sintering, the densities of the fin and chamber reached 96%. With only 32 cooling fins and a small fan installed, the thermal resistance of the heat sink was 1.156 ℃/W, and the power dissipation was 40W when the junction temperature was 70℃. When copper powder was sintered onto the chamber to make a vapor chamber, the thermal resistance decreased to 1.046℃/W.

PM recent developments focus on increasing this technology's competitiveness when compared to wrought materials. Warm compaction allows the replacement of a double press double sinter process with a single warm press and sintering step, thus allowing cost and time savings. Moreover there are added benefits to consider such as reducing work in process and lessening part's logistics cost. This paper presents a successful industrial trial to replace a double press-double sinter process with a warm die compaction and sintering process. The part chosen was a high performance gear containing 0,9% wt. carbon. Sintering was conducted in a belt furnace at in a nitrogen rich atmosphere with rapid cooling process in order to obtain a quasi fully martensitic structure with a minimum of 700HV0,1 and 450HV10 after annealing. The balance between properties and cost is favoured by the use of a singular lubricant developed in a Eureka frame project together with POMETON S.A. and die warm compaction. Warm compaction is only needed to be effective on the gear teeth, in order to achieve the required properties. Therefore only the die is actually heated. This simplified system avoids flow rate problems typically involved when using more elaborate warm compaction equipments.
