Authors made an experiment to know the relation of surface doses and multiple factors of exposure by using grids, fields, tube voltages objects and distances and obtained the results as follows: 1. Surface doses were increased in proportion to the thickness of objects. 2. Surface doses were more influenced when irradiated fields were small and tube voltages were low. 3. Surface doses were a logarthmic proportion to the focus-object distance. 4. Multiple factors of exposure by using grid were under the control of the thickness of objects, irradiated fields and tube voltages but the relation of them were not fixed.

The administration of a regional public hospitals are expending from profit preference to publicity preference. The weight rate for a profitability and publicity of performance assessment has changed from 84:16 which was resulted by the assessment executed firstly in 1989 to 39:61 as resulted in 2004, the final assessment execution in 2005. Regional public hospitals are exerting and promoting a magnification in public sector to raise up the public-score. With comparison between publicity scores and profitability scores in original scores basis excluding weight rate, the publicity scores ranked higher than profitability scores although the latter was higher by 2002. However, for the administration performance of the regional public hospitals, the deficits increased 11 times from \92.6billion deficits with \460.3billion cost increased by 457% although income as \367.7billion increased by 394% comparing the last 2004 year to the first 1989 year for profit & loss statement of a regional public hospitals. There was analysis for the relation in yearly basis partitioning publicity and profitability for the assessment scores of the to regional public hospitals confirm the accumulated deficits of the hospitals like this attribute to the extension of public sector. The result showed that there was distinct plus relationship from 1999 although a minus relationship in general until 1997 except 1992 and there is a more plus relationship as approaching 2004. That is, it is hard to tell that the accumulated deficits increase of regional government medical center attributed to extension of public sector. On the contrary, the analysis showed the extension of public sector has a mutual relationship with uplift of profitability Meanwhile, it showed that operation cost rate and labor cost are the factors which influence a revenue & expenditure rate among the profitability index according to the results of relation analysis for the representative index of profitability and that of publicity.

A lot of local colleges are public relation(PR) using on off line media. However, to examine the effectiveness and efficiency can be maximized to promote research is still lacking. This study was presented to the utilization of the Internet media in local colleges. As a result, local college students were used more offline than online media. Add admission period, girls were higher utilization of the internet entrance site. When nonscheduled admission, vocation high school students were more internet media use. Academic high school students used the internet media, when add admission period.

Polymorphisms in miRNA binding sites have been shown to affect miRNA binding to target genes, resulting in differential mRNA and protein expression and susceptibility to common diseases. Our purpose was to predict SNPs (single nucleotide polymorphisms) within miRNA binding sites of inflammatory genes in relation to gastric cancer. A complete list of SNPs in the 3'UTR regions of all inflammatory genes associated with gastric cancer was obtained from Pubmed. miRNA target prediction databases (MirSNP, Targetscan Human 6.2, PolymiRTS 3.0, miRNASNP 2.0, and Patrocles) were used to predict miRNA target sites. There were 99 SNPs with MAF>0.05 within the miRNA binding sites of 41 genes among 72 inflammation-related genes associated with gastric cancer. NF-${\kappa}B$ and JAK-STAT are the two most important signaling pathways. 47 SNPs of 25 genes with 95 miRNAs were predicted. CCL2 and IL1F5 were found to be the shared target genes of hsa-miRNA-624-3p. Bioinformatic methods could identify a set of SNPs within miRNA binding sites of inflammatory genes, and provide data and direction for subsequent functional verification research.

In this paper, it is examined how the amount of review time per applicant to a college admission officer system is connected with the performance of the selected students after they enter the college. About five years ago, college admission officers system has been introduced to Korea as a government policy. Thus, for most Korean college, there is not enough number of admission officers, while it takes substantial time to find out whether an applicant has potential ability or not. Thus, it is required to find out some policy alternatives to solve this discrepancy. In this paper, a simulation model is built using System Dynamics theory and simulated to understand the relation between the amount of review time and the performance of the selected students. Finally, some implications and policy suggestions are derived from the simulation results.

Background: The possibility that electromagnetic fields (EMF) exposure may increase male breast cancer risk has been discussed for a long time. However, arguments have been presented that studies limited by poor quality could have led to statistically significant results by chance or bias. Moreover, data fo the last 10 years have not been systematically summarized. Methods and Results: To confirm any possible association, a meta-analysis was performed by a systematic search strategy. Totals of 7 case-control and 11 cohort studies was identified and pooled ORs with 95% CIs were used as the principal outcome measures. Data from these studies were extracted with a standard meta-analysis procedure and grouped in relation to study design, cut-off point, exposure assessment method, adjustment and exposure model. A statistical significant increased risk of male breast cancer with EMF exposure was defined (pooled ORs = 1.32, 95% CI = 1.14-1.52, P < 0.001), and subgroup analyses also showed similar results. Conclusions: This meta-analysis suggests that EMF exposure may be associated with the increase risk of male breast cancer despite the arguments raised.

This study suggests the direction to narrow down the difference between financial and tax accounting in relation to borrowing costs. Accounting for capitalization of borrowing costs under accounting standards for non-public entities should be revised to converge into KIFRS. The provision of corporate income tax law relating to capitalization of borrowing costs should be applied on the optional basis rather than compulsory application especially for non-public entities. The range of qualifying assets for capitalization under the tax law should be reviewed to comply with KIFRS.

This study is to inquire into the sexual consciousness and values of students majoring in public health-related subjects, as well as into whether there are differences between male students and female students. This study was conducted on randomly-selected students majoring in public health-related subjects at junior colleges in South Chungcheong Province. The questionnaire, used in this study, was remade on the basis of philological reviews and previous studies, and a total of 208 questionnaires were re-collected. In relation to the question about chance of sex education, 56.7% of respondents answered, '4 or more chances'. In relation to the question about the source of sex information, 37.5% of respondents referred to 'their friends.' In the case of premarital sex, 51.4% answered, 'it amounts to nothing in pairs of lovers.' In conclusion, the university authorities need to aggressively support students in order that desirable sex educations can be given to students and they can have right sexual consciousness and have the mature and responsible attitude to sex.
