원통형 카트리지 집진 필터는 동일한 크기의 일반 백필터에 비해 2-4배 정도의 여과면적을 확보할 수 있기 때문에 동일한 처리유량에 대해서 탈진주기를 2배 이상으로 증가시킬 수 있다. 또한 여과속도를 일반 백필터와 같게 할 경우, 적용되는 필터의 수를 줄일 수 있어 집진 장치가 차지하는 공간을 절약할 수 있다는 장점을 갖고 있다. 이러한 원통형 카트리지 집진 필터의 맡은 장점에도 불구하고 카트리지 집진 필터의 집진 특성에 관한 연구는 매우 저조하며, 대부분 필터 제조업체의 경험에 의해 산업체에 적용되고 있다. (중략)

This paper tried to identify the impacts of job stress on burnout and organizational commitment in the casino industry. Prepared questionnaires were distributed to 300 sample employees working in domestic casino, then used for data analysis 283. The results of this study are as follows: Firstly, dissimilarity have a positive effect on emotional exhaustion. Secondly, role conflict and dissimilarity have a positive effect on lack of accomplishment. And role ambiguity have a negative effect on lack of accomplishment. Also role conflict and dissimilarity have a positive effect on depersonalization. And role ambiguity have a negative effect on depersonalization. Thirdly, role ambiguity have a positive effect on affective commitment. But, job stress have not effect on continuance commitment. This study will be able to contribute raising competitiveness of casino corporate and efficiency of human resource management.

The objective of this study is to analyze the correlations between the chronic illnesses and congenital diseases of the chronic elderly invalids in nursing homes, as well as to examine the impact of stress scale and the factors affecting the emotional burnout scale. This study conducted Seoul survey from March 15 to May 31, 2013, targeting 147 seniors in nursing homes who were suffering from the four most common chronic illnesses. Analyses performed in this study include frequency, correlation and simple regression analyses, t-test and one-way analysis of variance, etc. All of the empirical analyses were conducted at 5% level of significance. The result of the study shows that there is a high correlation between the chronic invalids and their congenital diseases determined by the four pillars of destiny and that, if they are found to have a chronic illness, patients experience a high level of stress. Persons who score higher on the stress scale tend to score higher in the emotional burnout scale.

The purposes of this study were to extract the effects of emotional labor, self-efficacy and burnout on customer-oriented selling behavior of salesperson by literature review and to examine the effect variables on customer-oriented selling behavior empirically. The questionnaire was administered to 400 salespersons who were selling clothes, cosmetics, shoes, leather products and accessories in department stores located in Kwang-ju city during August 18-24, 2006. Data collected from 307 salespersons were analyzed by using descriptive statistics, factor analysis, t-test, ANOVA, Duncan-test, correlation, regression analysis and path analysis. The results were as follows: First, Salesperson's emotional labor was composed of two factors; emotional labor toward the customer and emotional labor toward the organization. Second, Salesperson's emotional labor had negative significant influence on customer-oriented selling behavior. Specifically, the emotional labor toward the organization negatively influenced on customer-oriented selling behavior, but the emotional labor toward the customer positively influenced on customer-oriented selling behavior. Third, Salesperson's emotional labor positively influenced on burnout. Specifically, emotional labor toward organization significantly influenced on burnout, but emotional labor toward customer did not influenced on burnout. Fourth, Salesperson's self-efficacy positively influenced on customer-oriented selling behavior. Fifth. Salesperson's self-efficacy negatively influenced on burnout. Finally, Salesperson's burnout negatively influenced on comer-oriented selling behavior. The direct effect of salesperson's self-efficacy on customer-oriented selling behavior was large than the indirect effect of salesperson's self-efficacy mediate burnout. But the indirect effect of salesperson's emotional labor mediate burnout was large than the direct effect of salesperson's emotional labor on customer- oriented selling behavior.

This study had collected 275 dental hygienists working in Busan, Ulsan, and Gyungnam area, in order to investigate burnout, job satisfaction and turnover of dental hygienists and find relationship between these. The obtained results were as follows; 1. The average burnout points are 2.61, and we could gain each point as follows; emotional burnout 2.76, physical burnout 3.41, and declination of job efficiency 2.77. 2. The job satisfaction was under the greatest influence of the emotional burnout, followed by declination of job efficiency, physical burnout. All the factors had a negative impact on their job satisfaction. 3. The turnover intention was under the greatest influence of the communication, followed by workload, freedom factor, rationality of organization, and possibilities of workplace. All the factors had a negative impact on their turnover intention. Those who were less satisfied sought new employment more often.

This paper tried to identify the impacts of emotional labor on burnout and job satisfaction in the casino industry. Prepared questionnaires were distributed to 300 sample employees working in domestic casino, then used for data analysis 300. The results of this study are as follows: Firstly, surface acting have a positive effect on emotional exhaustion, lack of accomplishment and depersonalization. But deep acting have a negative effect on emotional exhaustion. And deep acting, emotion control have a negative effect on lack of accomplishment and depersonalization. Secondly, surface acting have a positive effect on job environment. Also deep acting, emotion control have a positive effect on rewards and value sharing. And emotion control have a positive effect on work environment. Thirdly, deep acting have a negative effect on job environment. Also, surface acting have a negative effect on rewards and value sharing.

A study is to predict the effective pulsing distance following to the pulsing pressure, nozzle diameter, filtration velocity using numercial analysis techniques and use it as an efficient operation condition and economic data for on-line type pulse air jet bag filter. Filtration area 6 m² condition, calculate filter resistance coefficient for simulation through the primary experiments using coke dust. For CFD simulation, analysis pulsing characteristics about nozzle diameter, filtration velocity and pulsing pressure. The maximum pulsing length of on-line type pulse air jet bag filter, in 10mm nozzle, filtration velocity 1.5m/min and pulsing pressure 5 bar conditions, is 2,285 mm, maximum length is 76.2% of the total filter bag, which is sufficient to pulsing. In 12mm nozzle, pulsing pressure 5 bar and filtration area 1.22 m² conditions, the maximum pulsing length of on-line type pulse air jet bag filter is 1,744~2,952 mm, and the maximum length is 2,952 mm indicates pulsing air can be reached to the bottom of filter bag. When the nozzle diameter is increased 8mm to 10mm, maximum pulsing length is extended 40~47%, and increased 10mm to 12 mm, maximum pulsing length is extended 10~17%. For effective pulsing, over the 5bar of pulsing pressure and larger than 10 mm of nozzle diameter are required.

최근, 고효율 집진장치로 새롭게 부각되고 있는 hybrid 집진 시스템은 2가지 이상의 집진 메카니즘을 1기의 단일 시스템에 결합시킴으로써, 시스템의 고성능화와 장치의 규모 및 설치비를 줄일 수 있는 중요한 장점을 지니고 있다. 본 연구에서는 전기력, 원심력 및 impaction 메카니즘(시스템 내부에 임팩션 효과를 유발시키는 impaction porous plate의 설치)을 결합하여 99% 이상의 집진효율을 기대할 수 있는 hybrid 집진 시스템의 특성을 연구하였다. 이는 99%의 고효율을 유지하는 기존 여과집진장치의 문제점인 낮은 여과속도(즉, 장치의 대형화), filter의 유지ㆍ관리 및 탈진 공정에 의한 연속 조업의 어려움 등을 동시에 해결할 수 있는 집진 시스템으로 이에 대한 연구가 수행되면 기존 가장 광범위하게 사용되지만, 많은 문제점을 지니고 있는 여과집진기를 대체할 수 있는 새로운 개념의 집진 시스템이 개발될 수 있을 것으로 생각된다.

This study aimed to evaluate the validity of an exhausted injector design for filtration system and the performance characteristics thereof. The evaluation was intended through computational fluid dynamics(CFD) analysis based on computer simulation rather than through prototype fabrication and testing. Furthermore, the design of experiment was used to create an experimental design table by which the reaction characteristics of response factors were analyzed for design parameters. All experiments were substituted with computer simulations. Lastly, an optimal design model for the injection tubes was determined based on response surface method algorithms.
