In this paper, synthesize MoO₃ particles with various particle properties by control growth influence factors was mainly studied. The experimental conditions were established in molar ratio of Mo:urea and pH levels. The plate-type of MoO₃ particles were formed without proceeding any established conditions, but the rod-shape particles were formed by adjusting molar ratio of Mo:urea. Also, different ranges of the particle size were formed by adjusting experimental conditions. Through the results, it was confirmed that particles with a size in the range of 300 ~ 400 nm were obtained by adjusting precursor concentration and the micrometer size of particles were formed by increase pH levels. The properties of the particles formed accordingly by setting various factors that can affect the growth process of MoO₃ particle was analyzed as variables and the particle growth behavior was also observed.

Primary breast lesions diagnosed by fine needle aspiration cytology, confirmed by histologic examination were analyzed by morphometry to evaluate the difference between benign and malignant lesions, and the methods obtaining the sample. four size factors and 5 form factors were evaluated in 22 fibroadenomas and 20 carcinomas by image analyzer(Zeiss Ibas 2000) using the H-E stained slides. Nuclear size was significantly larger in the carcinoma cells than fibroadenoma cells both in the cytology and biopsy specimens, but the form factors were not significantly different. Both fibroadencma and carcinoma cells were significantly larger in cytologic smear than histologic section. The cells in the cytology were more regular and round than those in histology, but not statistically significant. Fibroadenomas having cellular proliferation and atypism exhibited larger size and more irregular nuclei than non-proliferative fibroadenoma, but not statistically significant. Therefore nuclear morphometric analysis can be a helpful method to diagnose the questionable breast lesions and is a method appropriate for use as a quality control procedure in the fine needle aspiration cytology.

쐐기인자는 중심축선상의 어느 특정 깊이에서 측정한 흡수선량으로써 쐐기가 제거된 선량과 쐐기가 부착된 선량의 비로써 정의된다. 본 연구에서는 조사야의 크기별 쐐기인자의 의존성을 살펴보았다. 쐐기인자들은 Varian Clinac1800의 6MV와 15MV 광자선과 Philips SL75/5 의 5MV광자선의 쐐기에 대하여 여러 조사야에 따라 구하였다. 특정 조사야 (10cmx10cm) 에서 구한 단일 쐐기인자를 모든 조사야에 적용시키는 것은 타당치가 않다. 두꺼운 쐐기일 경우 특히 SL75/5 의 5MV 광자선에서 autowedge 의 30cmx30cm 조사야 일 때 오차가 중요하였다(6.6%). 따라서 이러한 쐐기의 치료선량을 계산할 때는 조사야 크기에 따른 쐐기인자를 적용하여야 한다.

The purpose of this study is to examine a potential association between community factors and the establishment of Local Healthy Family Support Centers (LHFSCs). Community factors were population size, community size, local finance independency, number of workplaces per 1,000 people, number of colleges, political party affiliation of mayor, and political party affiliation of congressman. Data of this study were collected from the census indicators of 222 communities from 2004 to 2014 and analyzed by frequency, mean, geographical information system mapping, and the binary logit analysis. The results of this study are as follows. First, LHFSCs are less likely to be established in communities in the provinces of Gangwon, Chungbuk, and Gyeongbuk. Second, the population size was positively related to the establishment of LHFSCs. Third, finance independency was positively associated with the establishment of LHFSCs. Forth, a mayor was more likely to establish LHFSCs if they were affiliated with the ruling conservative political party. However, the establishment of LHFSCs was not affected by other factors such as community scale, number of workplaces per 1,000 people, the number of colleges, and party affiliation of congressman. Thus, the conclusion suggests family policy implications to improve the geographical imbalance of LHFSCs based on the analysis results.

This paper investigates the effects of operating conditions of an air classifier mill (ACM) on the particle sizes of PVC and rice hull. Based on the Box-Behnken matrix, the pulverization experiments were performed considering three operating factors: the air flow rate, the classifier speed and the mill speed. The response surface methodology was applied to identify the effects of the operating factors on the particle size. Results show that the particle sizes are governed by the linear variations of the operating factors. As less air is supplied and the mill rotates more slowly, the powder of both PVC and rice hull becomes finer. Furthermore, the classifier speed has a significant effect on the PVC powder but almost no effect on the rice hull powder. Thus, it is found that strong interactions exist between the material characteristics of a particle and the operating conditions of the ACM.

Purpose - The current study aims to examine the effect of social network factors on travel agency employees' occupational outcomes such as job performance and job satisfaction through innovation behavior in a comprehensive model. Research design, data, and methodology - Based on a theory of social network, the concept of social network was assessed by three factors: a) network size, b) network range, and c) tie strength. To test the proposed hypotheses, structural equation modeling (SEM) was employed based on data from 197 travel agency employees in Korea. Result - The results showed that the associational activity of network size had a positive effect on innovation behavior, while the network range of network size had a significant negative effect on innovation behavior. Subsequently, innovation behavior positively influenced on job performance and job satisfaction, respectively. Conclusions - The results offer some insights into the extended model and have important managerial implications for Korean travel agencies. More specifically, considering diverse domains of social network and organizational research, this study advances critical utility of social network factors in a high facilitating level of innovation behavior, which can help travel agency employees promote their job performance and job satisfaction.
