This essay attempts to evaluate the pessimistic induction within the case of the historical development of space-time theories, which are claimed to undergo a radical ontological change providing evidence for the pessimistic induction. In my view, this claim misleads us to see the discontinuity of the structure of classical and relativistic space-time by means of a doubtful interpretation of space-time theories, which holds that space-time causally explains the phenomena of motions.

Asbestos have been used around the world by physical and chemical characteristics that are a reliable and cost-effective. But asbestos, once called the miracle of mineral, is now a quiet time bomb. Asbestos hazards have been studied and the government has pursued 'Comprehensive Measures for Asbestos Management' jointly with related departments. As a part of plan, Ministry of Environment is to introduce legislation 'Asbestos Safety Management Act' through Environment Announcement No. 2010-108. The same Act. 24 shows as follows. Minister of Environment or governor should do survey on the actual condition targeting rural buildings with slates and partly or fully fund to dissolve, remove asbestos slate which was used in each building. However, the local survey was only conducted by each municipality regionally. And there is no actual condition data by area, application and year, and there was no data on disposal costs concerning asbestos slate buildings In this study, discharge of asbestos slate was calculated per unit area and formula was developed with regression analysis. In addition, Demolition, dismantling, disposal costs were computed via a phone survey to disposal companies and then this study proposed standards for this.

Korea mountain ginseng known as oriental miracle drug is an important medicinal plant. The effect of mountain ginseng adventitious roots extract has been described. The valuable root of mountain ginseng contained several kinds of ginsenosides that have been confirmed to have many active functions for the human body. However, the study of mountain ginseng has a limit because the price of wild ginseng is very expensive and rare. The mountain ginseng adventitious roots were derived from mountain ginseng callus that were induced from mountain ginseng roots. Adventitious roots were separated from callus and grown in solid media(Murachige and stoog media). It was cultured in a 20L bioreactor. After culturing for 40days, adventitious roots were harvested. Afterwards the harvested mountain ginseng adventitious roots were dryed and extracted. We examined the effect on melanogenesis of mountain ginseng adventitious roots extrac. Here, we report the inhibitory effect of melanin biosynthesis on the adventitious roots extract of In vitro test. Also, we assessed the safety of adventitious roots extract. In vitro, cytotoxicity of adventitious roots extract was assessed in mouse fibroblast using two method: The neutral red uptake assay and the MTT assay. In vivo, the allergic and irritant were patch tested in 30 patients. Consequently, extract of mountain ginseng adventitious roots have inhibitory effect on melanin biosynnthesis in B-16 melanoma cell test, tyrosinase inhibitory test and DOPA auto-oxidation test. There were decreased 86%(0.5% concentration), 45%(1% concentration) and 61%(1% concentration), respectively

As small-scale libraries such as Children Library, Small Library, Miracle Library, have recently increased in number, it is required to establish the library consulting system in order to provide them with special knowledges and experiences necessary for library construction and operation. The result of the survey about public librarian's opinions confirms that the latent demand for library consulting is very high. In case of our country where the social experience in library consulting service is insufficient, it is desirable that the library consulting service be executed by the government offices as public service.

Background: This study investigated the influence of religious beliefs on the health of cancer patients and identified the factors contributing to the influence. Materials and Methods: A questionnaire survey was conducted using a convenient sampling method. A structured questionnaire was used to the samplings, and the data of 200 cancer patients were collected. Results: The effects of religion on the health of cancer patients achieved an average score of 3.58. The top five effects are presented as follows: (a) Religion provides me with mental support and strength, (b) religion enables me to gain confidence in health recovery, (c) religion motivates me to cope with disease-related stress positively and optimistically, (d) religion helps me reduce anxiety, and (e) religion gives me courage to face uncertainties regarding disease progression. Moreover, among the demographic variables, gender, type of religion, and experience of religious miracles contributed to the significantly different effects of religion on patients. Specifically, the effect of religion on the health of patients who were female and Christian and had miracle experiences was significantly (p< .01) higher than that on other patients. Conclusions: These results are helpful in understanding the influence of religious beliefs on the health of cancer patients and identified the factors contributing to the influence. The result can serve as a reference for nursing education and clinical nursing practice.

The purpose of this study was to introduce a new in vitro method for evaluating the antimicrobial activity of toothpaste, reflecting the actual toothbrushing time and the dilution of toothpaste by salivation. We designed three experimental groups and one negative control group. The experimental groups were (1) 90 μL of toothpaste + 10 μL 1X phosphate-buffered saline (PBS, 9/10 dilution group), (2) 50 μL of toothpaste + 40 μL 1X PBS (1/2 dilution group), and (3) 25 μL of toothpaste + 65 μL 1X PBS (1/4 dilution group). During toothbrushing, saliva is continuously secreted into the oral cavity and the toothpaste concentration is diluted over time during toothbrushing. Therefore, the 1/2 and 1/4 dilution experimental groups were added. The negative control group was toothpaste diluted 20,000-fold with 1X PBS. Miracle Fresh Doctor toothpaste and Streptococcus mitis KCOM 1350, Prevotella intermedia KCOM 1107, Fusobacterium nucleatum subsp. polymorphum KCOM 1322, and Aggregatibacter actinomycetemcomitans KCOM 1306 were used as the toothpaste and target bacterial strains, respectively. The number of bacterial cells plated on agar plates in the negative control group was 1,000 CFU. If the number of colonies on the experimental group plate was less than one, the treatment was considered to have > 99.9% bactericidal activity. These results suggest that this new in vitro method for antimicrobial evaluation could be used as the standard method for testing the antimicrobial activity of toothpaste.
