This paper is mainly interested in customer's(fan's) royalty to professional sports in sports industry. The royalty is studied with the royalty to several products and a service, so that we can obtain the comparison between both the former and the latter royalty. Interested professional sports, products and service are baseball, basketball, soccer, beer, cu, cola/cider, etc, and we will call each of them 'item'. The seven related hypotheses are considered. In hypotheses the dependent variable is royalty to nine items, and the independent variables are rune items, and customer's sex and major. For testing hypotheses, a questionaire is used, and reliability is checked with Cronbach's Alpha and correlation coefficients. For some items the royalty is significantly strong. Rather, even if some item has bad quality, it is found that customers can be royal to that item. We can identify some of those items through the results of this study. The strong significant results will be useful for the customer management. Additional studies are required for nonsignificant results which seems to be useful, and they are noted in the final part of the paper.

The purpose of this study was to investigate consumer shopping orientation toward foreign brands in the context of clothing involvement, ethnocentrism, country-of-orion effects and demograpic variables. But in this paper, to begin with, shopping orientation was studyed in connection with ethnocentrism and country-of-orion effects. The questionnaire was distributed to 300 female consumers over twenties living in pusan area and finally 213 data sets were used for statistical analysis.8y factor analysis,5 shopping orientation factors were identified: following to foreign brands, desire for flaunt, preference to domestics, favor to foreign brands and country-of-orion consciousness. By univariate analysis, consumer's disposition of ethnocentrism was studyed and consumers were divided into 3 groups according to disposition of ethnocentrism through fast cluster analysis. Resurts reveled that Korean consumers have strong ethnocenterism. And country-of-orion effects were studyed. Consumers are favorable toward foreign brands and products, especially toward Italy and France goods, except Hongkong and China goods nevertheless strong ethnocentrisuL As a result of canonical correlation analysis about shopping orientation factors and ethnocenterism revealed that ethnocenterism correlated negatively with one factor (following to foreign brands) and positively with another (preference to domestics).

We present the properties of globular cluster systems for 10 early-type galaxies in low density environments obtained using deep images from the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST). Using the ACS Virgo Cluster Survey as a counterpart in high-density environments, we investigate the role of environment in determining the properties of their globular cluster systems. We detect a strong colour bimodality of globular cluster systems in half of our galaxy sample. It is found that there is a strong correlation between the colour and richness of globular cluster populations and their host galaxy luminosities: the less bright galaxies possess bluer and fewer globular clusters as also seen in rich cluster environments. However, the mean colour of globular clusters in our field sample are slightly bluer than those in cluster environments at a given galaxy luminosity, and the colour of the red population has a steeper slope with absolute luminosity. By employing the YEPS simple stellar population model, the colour offset corresponds to metallicity difference of $\Delta$[F e/H ] ~ 0.15 - 1.20 or an age difference of $\Delta$age ~ 2 Gyr on average, implying that GCs in field galaxies appear to be either less metal-rich or younger than those in cluster galaxies. Although we have found that galaxy environment has a subtle effect on the formation and metal enrichment of GC systems, host galaxy mass is the primary factor that determines the stellar populations of GCs and the galaxy itself.

Although corporate social responsibility (CSR) is an extensively studied topic, its determinants in the field of Islamic banking are scarce. In Bangladesh, CSR plays a vital role in gaining customer loyalty and confidence. Therefore, this research aims to identify and analyze the influence of the Shariah Supervisory Board (SSB) and the Shariah Audit Committee (SAC) on CSR adoption in Islamic banks in Bangladesh. The study population is managers and second managers of 160 Islamic bank branches of different commercial banks in Dhaka, Bangladesh. The sampling technique used is convenience sampling where the first available primary data source was used for the research without additional requirements. The study developed a survey questionnaire from examining previous related studies in Islamic banking and CSR context. The final sample size in this research was n = 309, indicating the survey response rate was about 97%. The study used SPSS 23.0 software to interpret the statistical findings, and the findings revealed that support from the SSB and the presence of a strong and effective SAC has a strong correlation with CSR adoption and significantly influence CSR adoption in Islamic banks in Bangladesh. Finally, the study proposes several significant and crucial policy guidelines for Islamic bank branches to adopt CSR activities.

Objectives: The aims of this study were to quantify tug-back by measuring the pulling force and investigate the correlation of clinical tug-back pulling force with in vitro gutta-percha (GP) cone adaptation score using micro-computed tomography (${\mu}CT$). Materials and Methods: Twenty-eight roots from human single-rooted teeth were divided into 2 groups. In the ProTaper Next (PTN) group, root canals were prepared with PTN, and in the ProFile (PF) group, root canals were prepared using PF (n = 14). The degree of tug-back was scored after selecting taper-matched GP cones. A novel method using a spring balance was designed to quantify the tug-back by measuring the pulling force. The correlation between tug-back scores, pulling force, and percentage of the gutta-percha occupied area (pGPOA) within apical 3 mm was investigated using ${\mu}CT$. The data were analyzed using Pearson's correlation analysis, one-way analysis of variance (ANOVA) and Tukey's test. Results: Specimens with a strong tug-back had a mean pulling force of 1.24 N (range, 0.15-1.70 N). This study showed a positive correlation between tug-back score, pulling force, and pGPOA. However, there was no significant difference in these factors between the PTN and PF groups. Regardless of the groups, pGPOA and pulling force were significantly higher in the specimens with a higher tug-back score (p < 0.05). Conclusions: The degree of subjective tug-back was a definitive determinant for master cone adaptation in the root canal. The use of the tug-back scoring system and pulling force allows the interpretation of subjective tug-back in a more objective and quantitative manner.

본 연구에서는 최근 자주 거론되는 녹조발생의 주요 원인을 찾아보고자 하였다. 지난 십년이상의 기상자료 및 수질에 대한 실측자료를 이용하여 녹조원인에 대한 통계적 접근을 시도하였다. 팔당호를 대상으로 한 연구에서 조류예보일수에 일정한 추세를 발견할 수는 없지만 발생년도에는 10일 이상씩 나타나는 특징을 보여 주고 있으며 최근 5년간은 발령일수가 증가하고 있어 주의해야 할 것으로 판단되었다. 유속의 자료 대신 사용된 방류량을 보면 조사기간 중 세 배 정도의 차이가 나는 해도 관찰되었다. 클로로필a에 대한 다른 지표들의 상관계수를 보면 뚜렷한 한 가지 지표로 나타나지 않아서 상관계수 0.4를 넘는 요인은 없었다. 그 중 중요한 요인으로 나타나는 것은 일조시간, BOD, 그리고 방류량이며 일조시간과 BOD는 양의 상관 그리고 강수량과 방류량은 음의 상관을 나타내고 있어서 광합성미생물에 의한 현상으로서 타당한 결과로 보였다. 수온과 총인농도는 중요한 요인이 될 것으로 예상되었으나 결과는 낮은 상관성을 보였다. 이상의 결과로 판단할 때 조류발생에는 여러 가지 요인이 복합적으로 작용하며 그중 일조시간, BOD, 그리고 유속 또는 방류량은 중요한 요인으로 판단된다. 방류량과 다른 요소와의 상관관계도 조사하였다. 강수량과 수온이 양의 상관을 보이는 것은 계절적인 효과로 타당해 보였다.

A good understanding of normal modal variability of civil structures due to varying environmental conditions such as temperature and wind is important for reliable performance of vibration-based damage detection methods. This paper addresses the quantification of wind-induced modal variability of a cable-stayed bridge making use of one-year monitoring data. In order to discriminate the wind-induced modal variability from the temperature-induced modal variability, the one-year monitoring data are divided into two sets: the first set includes the data obtained under weak wind conditions (hourly-average wind speed less than 2 m/s) during all four seasons, and the second set includes the data obtained under both weak and strong (typhoon) wind conditions during the summer only. The measured modal frequencies and temperatures of the bridge obtained from the first set of data are used to formulate temperature-frequency correlation models by means of artificial neural network technique. Before the second set of data is utilized to quantify the wind-induced modal variability, the effect of temperature on the measured modal frequencies is first eliminated by normalizing these modal frequencies to a reference temperature with the use of the temperature-frequency correlation models. Then the wind-induced modal variability is quantitatively evaluated by correlating the normalized modal frequencies for each mode with the wind speed measurement data. It is revealed that in contrast to the dependence of modal frequencies on temperature, there is no explicit correlation between the modal frequencies and wind intensity. For most of the measured modes, the modal frequencies exhibit a slightly increasing trend with the increase of wind speed in statistical sense. The relative variation of the modal frequencies arising from wind effect (with the maximum hourly-average wind speed up to 17.6 m/s) is estimated to range from 1.61% to 7.87% for the measured 8 modes of the bridge, being notably less than the modal variability caused by temperature effect.

Background: Breast cancer is the most common malignancy in women worldwide and its incidence is generally increasing. In 2012, it was the second most common cancer in the world. It is necessary to obtain information on incidence and mortality for health planning. This study aimed to investigate the relationship between the human development index (HDI), and the incidence and mortality rates of breast cancer in the world in 2012. Materials and Methods: This ecologic study concerns incidence rate and standardized mortality rates of the cancer from GLOBOCAN in 2012, and HDI and its components extracted from the global bank site. Data were analyzed using correlation tests and regression with SPSS software (version 15). Results: Among the six regions of WHO, the highest breast cancer incidence rate (67.6) was observed in the PAHO, and the lowest incidence rate was 27.8 for SEARO. There was a direct, strong, and meaningful correlation between the standardized incidence rate and HDI (r=0.725, $p{\leq}0.001$). Pearson correlation test showed that there was a significant correlation between age-specific incidence rate (ASIR) and components of the HDI (life expectancy at birth, mean years of schooling, and GNP). On the other, a non-significant relationship was observed between ASIR and HDI overall (r=0.091, p=0.241). In total, a significant relationship was not found between age-specific mortality rate (ASMR) and components of HDI. Conclusions: Significant positive correlations exist between ASIR and components of the HDI. Socioeconomic status is directly related to the stage of the cancer and patient's survival. With increasing the incidence rate of the cancer, mortality rate from the cancer does not necessariloy increase. This may be due to more early detection and treatment in developed that developing countries. It is necessary to increase awareness of risk factors and early detection in the latter.

Few public health researchers have paid research attention to the location of medical institutions in Korea. Previous studies were published in geography journals, and relied on limited data in terms of geographic regions and the type of medical institutions. This study utilized nationwide data covering 8 types of medical institutions. We obtained data from Health Insurance Review and Assessment Service and National Population and Housing Census. The correlation coefficients of resident, daytime, university-graduate population, and the population of different age groups (fewer than 15, 15~64, 65 or more) were compared to understand their relative association with the location of medical institutions. Medical clinic, dental clinic, oriental medical clinic, and pharmacy, all of which are almost completely operated by private sector, showed strong positive correlation with population. Hospital-level medical institutions, which are operated by both public and private sector, had moderate positive correlation. Daytime population and university-graduate population, rather than resident population, were more correlated with the location of medical clinics. The correlation coefficients of the population of 15~64 age group and the location of medical institutions were greater than that of other age groups. The results showed that daytime and university-graduate population are more important than resident population to explain the location of medicalrelated facilities. The results also suggests that the population of age groups (especially, 15~64) might be one of important influence factors in the location of medical institutions.

최근 인류가 초래한 지구의 온난화로 인하여 기온이 상승하고 이의 직접적인 반응으로 수온 증가가 감지되고 있다. 기온변화가 하천의 수질과 생태 환경에 미치는 영향을 추정하기 위해서는 수온 상승의 시기와 하천 어종에 대한 이해가 필요한데 이를 위하여 미래의 수온을 예측할 필요가 있다. 이에 하나의 사전연구로서 기온-수온 관계에 대하여 분석해 보았다. 2009년에서 2011년까지 3년 동안 환경부의 수질자동관측소에서 관측한 최소 873개에서 최대 1083개의 일 관측 자료를 바탕으로 자기상관관계와 교차상관관계를 조사해 본 결과 0.9 이상의 높은 상관관계를 보였다. 또 지체시간이 10일 미만에서는 기온의 자기 상관 계수가 수온의 가기 상관 계수보다 더 높은 것으로 나타났다. 관측자료의 이력현상을 분석하기 위하여 상승기와 하강기로 나누었는데, 관측지점에 따라서는 강한 이력현상을 보이는 지점도 발견되었다. 결국 기온-수온 관계를 구축함에 계절적인 이력현상이 고려되어야 정확도를 높일 수 있음을 유추할 수 있다.
