Due to the continuous expansion of the highway, the opening of the high-speed railway(KTX), etc, the demands of domestic air transport decreasing. In the circumstances, airports and local governments are spending themselves in taking a measure to activate local airports. In this aspect, this study seeks the smooth flow of human movement through the activation of Daegu International Airport by analyzing the present condition of Daegu International Airport in relation to the appearance of the high-speed railway, deducing plans for activating airports, and presenting the roadmaps for long-, mid- and short-term roles for the development of Daegu Airport, and Presents substantial fulfilling plans to secure the competitive power of Daegu International Airport by speeding up the flow of air goods of the area for the long run. It is suggested in the study that by setting up an organization exclusively responsible for activating Daegu International Airport in the city of Daegu, supporting local travel agencies to promote consistent demands, supporting aviation companies to employ Daegu International Airport as a major air base, establishing airlines with priority for airports that open newly in local cities of Japan and establishing and expanding airlines in China areas be promoted actively. Ministry of Construction & Transportation makes it a means of main airport Policy to only support Incheon International Airport to be a hub. However not only Incheon International Airport should be an amok representing the country, but also the wide Metropolitan area should supply the demands, and airports based in the West and East Coast areas need to be developed in the future. It is suggested that since air demands of domestic local airports are based on the demands of the of gin destination in neighboring region, multiple bases need to be developed. It is suggested that by developing not 1 in mega hub (Incheon International Airport) but 1 in mega hub. 2 in regional hub (the West and East Coast) and Jeju foy the tourism hub in our developing airports system.

The present study investigated regional and sex differences in knowledge, perception, cognition and behavior of fine-dust protective masks for periods of high concentration of fine dust in Korea. A total of 2,012 adults from seven provinces responded to the questionnaire. The results (all p<.05) showed that 78% of respondents considered pollution from China to be the greatest contributor of fine dust. Seoul and Gyeonggi residents more frequently checked fine dust forecasts than other provinces and consulted their smartphone applications to do so more than other residents. Jeju, Gwangwon, and Jeonla residents had less knowledge of KF 80, 94, and 99 masks than residents of other provinces. Gwangwon and Jeju residents had less trust in the effectiveness of protective masks than other residents. Females perceived themselves as unhealthier respiratory, more frequently checked the concentration of fine dust, trusted more the effectiveness of masks, and more frequently wore masks, compared to male respondents. Those who self-identified their respiratory function as poor, more frequently checked fine dust forecasting, and had greater knowledge of masks, which resulted in greater trust in the protective function of masks, and finally had higher wear frequency of masks for days with high concentrations of fine dust.

The natives of the genus Corbicula have shown worldwide dispersion in recent times, which has caused great ecological and economic impacts on the introduced ecosystems. The species reported from the genus have been consumed as food and explored for medicine with pharmacological activity. Consequently, the demand of Corbicula sp. in the South Korean domestic market has increased and so also it's associated import to the country. However, due to the absence of identification keys of imported Corbicula, the market is facing confronting situations. We hypothesized that the mitochondrial Cytochrome Oxidase I gene (CO-I) based molecular profiling could be a necessary technique for identification of Corbicula sp. in the South Korea domestic market. The genetic analysis identified both Corbicula japonica and Corbicula fluminea from the market foods. C. japonica and C. fluminea are inhabitants in Korea, but C. fluminea production has decreased in Seomjingang river basin. Therefore, C. fluminea identified from this study, is expected to be imported from China and would have a mixed sales in Seomjingang river side basin.

Background: Due to the strong inhibitory effects of $PPAR{\gamma}$ gene on the growth of cancer cells, the role of Pro12Ala polymorphism in $PPAR{\gamma}$ gene has been extensively investigated in cancer recently. However, the results were inconsistent according to cancer type. The aim of this study was to comprehensively evaluate the $PPAR{\gamma}$ Pro12Ala polymorphism and gastric cancer susceptibility. Materials and Methods: Search strategies were conducted in Pubmed, Medline (Ovid), Chinese biomedical database (CBM), China national knowledge infrastructure (CNKI), VIP, and Wanfang database, covering all publications, with the last search up to November 01, 2014. The strength of association between $PPAR{\gamma}$ Pro12Ala polymorphism and gastric cancer risk was assessed by OR with 95%CI. Results: A total of 546 cases and 827 controls in 5 case-control studies were included in this meta-analysis. The results indicated that the variant G allele carriers (CG+GG) had a 2.31 times higher risk for gastric cancer when compared with the homozygote CC (odds ratio (OR)=2.31, 95% confidence interval (CI)=1.67-3.21 for CG+GG vs. CC). In the subgroup analysis by ethnicity, significantly elevated risks were both found in Asians (OR=2.56, 95% CI=1.42-4.64) and Caucasians (OR=2.20, 95% CI=1.48-3.25). Similarly, in the subgroup analysis by H. pylori status, a significantly increased risk was identified in H. pylori (+) populations (OR=3.68, 95%CI=2.07-6.52), but not in H. pylori(-) populations (OR=1.17, 95%CI=0.58-2.39). Conclusions: This pooled analysis suggested that the $PPAR{\gamma}$ Pro12Ala polymorphism could be an independent predictive risk factor for gastric cancer especially in H. pylori infected populations in Asians and Caucasians. Nevertheless, prospectively designed cohort studies are needed to further investigate gene-gene and gene-environment interactions to confirm the combined effects of $PPAR{\gamma}$ Pro12Ala polymorphisms and H. pylori infection on gastric cancer risk.

Background: Several recent studies have explored associations between pre-mir-218 polymorphism (rs11134527) and cancer risk. However, published data are still inconclusive. To obtain a more precise estimation of the relationship in the Chinese population, we carried out a meta-analysis for the first time. Materials and Methods: Through retrieval from the PubMed, Medline, Embase, Web of Science databases, China National Knowledge Infrastructure and the Chinese BioMedical Literature Database, a total of four studies were analyzed with 3,561 cases and 3,628 controls for SNP pre-mir-218 rs11134527. We calculated odds ratios (ORs) and 95% confidence intervals (95%CIs) to explore the strength of associations. Results: The results showed that the rs11134527 polymorphism was associated with decreased cancer risk in GG versus AA and GG versus AA+AG models tested ( GG vs AA: OR=0.82, 95%CI: 0.71-0.94; GG vs AA+AG: OR=0.84, 95%CI: 0.74-0.96), and significantly decreased cervical cancer risk was observed in GG versus AA and GG versus AA+AG models (GG vs AA: OR=0.79, 95%CI: 0.66-0.94; GG vs AA+AG: OR=0.80, 95%CI: 0.68-0.94). However, no significant association between the rs11134527polymorphism and hepatocellular carcinoma risk was observed in all comparison models tested (AG vs AA: OR=0.94, 95%CI: 0.79-1.11; GG vs AA: OR=0.88, 95%CI: 0.70-1.10; GG+AG vs AA: OR=0.92, 95%CI: 0.79-1.08; GG vs AA+AG: OR=0.91, 95%CI: 0.75-1.11). Conclusion: The findings suggest that pre-miR-218 rs11134527 polymorphism may have some relation to cancer development in Chinese. However, well-designed studies with larger sample size and more detailed data are needed to confirm these conclusions.

Introduction: Although most prostate cancers initially respond to castration with luteinizing hormonereleasing analogues or bilateral orchiectomy, progression eventually occurs. Based on the exciting results of several randomized controlled trials (RCTs), it seems that patients with metastatic castration-resistant prostate cancer (mCRPC) might benefit more from treatment withabiraterone. Therefore we conducted a systematic review to evaluate the efficacy and toxicity of abiraterone in the treatment of mCRPC. Methods: Literature was searched from Embase, PubMed, Web of Science, and Cochrane Library up to July, 2013. Quality of the study was evaluated according to the Cochrane's risk of bias of randomized controlled trial (RCT) tool, then the Grading of Recommendations Assessment, Development and Evaluation (GRADE) System was used to rate the level of evidence. Stata 12.0 was used for statistical analysis. Summary data from RCTs comparing abiraterone plus prednisone versus placebo plus prednisone for mCRPC were meta-analyzed. Pooled hazard ratios (HRs) for overall survival (OS), radiographic progression-free survival (RPFS) and time to PSA progression (TTPP); Pooled risk ratios (RR) for PSA response rate, objective response rate and adverse event were calculated. Results: Ten trials were included in the systematic review; Data of 2,283 patients (1,343 abiraterone; 940 placebo) from two phase 3 trials: COU-AA-301 and COU-AA-302 were meta-analyzed. Compared with placebo, abiraterone significantly prolonged OS (HR, 0.74; 95% confidence interval [CI], 0.66 to 0.84), RPFS (HR, 0.59; 95% CI, 0.48 to 0.74) and time to PSA progression (HR, 0.55; 95% CI, 0.43 to 0.70); it also significantly increased PSA response rate (RR, 3.63; 95% CI, 1.72 to 7.65) and objective response rate (RR, 3.05; 95% CI, 1.51 to 6.15). This meta-analysis suggested that the adverse events caused by abiraterone are acceptable and can be controlled. Conclutios: Abiraterone significantly prolonged OS, RPFS and time to progression patients with mCRPC, regardless of prior chemotherapy or whether chemotherapy-na$\ddot{i}$ve, and no unexpected toxicity was evident. Abiraterone can serve as a new standard therapy for mCRPC.

The majority of drugs used in the treatment of superficial fungal infections has limited values due to its low efficacy or development of resistance. For the purpose of searching efficacious agent on the superficial fungal infections induced by dermatophytes which is regarded as the most malicious one, authors examined whether Chinae Rhizoma Extracts have significant on it. Extracts from Smilax china Linne used for the study are water extract (CRWE), ethanol extract (CREE) and methanol extract (CRME). In in vitro studies, the spores of the dermatophytes were inoculated on Sabouraud's glucose agar media which contained three extracts of Chinae Rhizoma in each concentration of $500\;{\mu}g/ml$, $1,000\;{\mu}g/ml$ and $5,000\;{\mu}g/ml$ respectively, and also $1,000\;{\mu}g/ml$ of salicylic acid and undecylenic acid $1,000\;{\mu}g/ml$ as comparable drugs. The growth of the dermatophytes were observed for 3 weeks. The species of the dermatophytes used in this experiment were Epidermophyton floccosum, Microsporum canis, Microsporum cookei, Microsporum gypseum, Microsporum nanum, Trichophyton mentagrophytes, Trichophyton rubrum, Trichophyton tonsurans and Trichophyton verrucosum distributed from The Institute of Tropical Medicine in Belgium. The results of the studies were as follows: 1. The growth of M. canis, M. nanum, T. mentagrophytes, T. rubrum & T. tonsurans were slightly inhibited in CRWE $1,000\;{\mu}g/ml$ and CRWE $5,000\;{\mu}g/ml$, and only slight inhibition on the growth of E. floccosum, M. canis and M. gypseum were observed in CRWE $5,000\;{\mu}g/ml$. 2. Complete inhibition of T. rubrum, moderate inhibition of M. nanum & T. tonsurans, and slight inhibition of E. floccosunl, M. canis, M. cookei & T. mentagrophytes in growth were observed in concentration of CREE $500\;{\mu}g/ml$. The growth of M. gypseum was slightly inhibited, moderate inhibition on the growth of M. canis, M. cookei & T. mentagrophytes, and complete inhibition of E. floccosum, M. nanum, T. rubrum & T. tonsurans in growth were observeed by CREE $1,000\;{\mu}g/ml$. With $5,000\;{\mu}g/ml$ of CREE, the growth of E. floccosum, M. canis, M. cookei, M. gypseum, T. mentagrophytes, T. rubrum & T. tonsurans were completely inhibited except T. verrucosum being showed slight inhibition. 3. In CRME $500\;{\mu}g/ml$, slight inhibition of T. verrucosum, moderate inhibition of M. gypseum and complete inhibition of E. floccosum, M. canis, M. cookei, T. mentagrophytes, T. rubrum & T. tonsurans in growth were observed. The growth of E. floccosum, M. canis, M. cookei, M. gypseum, M. nanum, T. mentagrophytes, T. rubrum & T. tonsurans were completely inhibited except T. verrucosum being showed moderate inhibition in both CRME $1,000\;{\mu}g/ml$ and CRME $5,000\;{\mu}g/ml$. 4. In $1,000\;{\mu}g/ml$ of undecylenic acid, slight inhibition of T. verrucosum and complete inhibition of E, floccosum, M. canis, M. cookei, M. gypseum, M. nanum, T. mentagrophytes, T. rubrum & T. tonsurans in growth were observed. From the above results, it was found that Chinas Rhizoma Alcoholic Extracts(CREE & CRME) exerted significant antifungal activity, and their effects were probably derived from the pharmacological actions of triterpenoidal saponin and steroidal saponin.

The early history of gun powder (black powder) and explosives was closely connected with the discovery of methods of preparing and purifing salpetre (potassium nitrate KNO$_3$). The Chineses apparently became acquainted with salpetre firstly on about 11th century, and they were possibly the original discoverers of salpetre for raw material of gun powder. The Egyptians called it “Chinese snow”, and it is significant that Chingis-Khan, the Mongol conqueror, took the Chinese eenginees with him in 1218 to use it for attacking the fortifications of the Persian cities. The black powder was invented by chance by Chinese alchemists during the Song dynasty (11th century) in the process of manufacturing medicine, and the powder was introduced to Europe by Mongol army. The manufacturing method of salpetre and gun powder was introduced to Korea from China in 1374, and the powder alld gunnery manufacturing project was developed by Mu Sun Choe(崔茂宣), the first Korean engineer late in Koryo dynasty. Coming in to Yi dynasty the explosive technic, extractive method of salpetre, and gunnery manufacturing process were developed greatly by Mu Sun Choe and Hai Sin Choe (崔海臣). However, confronting with the Japanes invasion at Imjin War (1597) with more powerful western style rifles which had been introduced from the Portuguese, on the contrary Korean army with the traditional guns couldn't compete with them. The Chochong(烏銃, the western rifle introduced in Japane) were much superior to the Chinese style traditional guns in the shooting power and striking efficiency. On the other hand, the Japanese battle ships armed only with the Chochong, when confronted with the Korean turtle shaped ships under the commanding of Admiral Yi Sun-Sin(李舞臣), were defeated by the Korean canons on the ships. The technical development of the modern powder industry in Korea. with the construction of four big explosive plants from 1930 to 1945, has resulted the mass-production of explosives. This study was purposed to investigate to the process with regard to the details of introduction to the explosive technology in Korea, and intended to give a help to the engineers who are engaged in study of the explosive technics by means of giving a spot light data on the early process of the designs, and making suggestion to the researchers for further study and invent a new and modern explosive.
