This study is to investigate how the expenditures for hypertension is affected by socioeconomic, health care resources, and health behavior factors with a special emphasis on geographic variations and to provide the data about regional management for hypertension. To analyze, we combined a unique data set including key indicators from Medical Service Usage Statistics 2012 by Region by National Health Insurance Corporation, Annual Community Health Survey 2012 by Korea Centers for Disease Control and Prevention and other government organizations at the 247 small administrative districts. We found that the average expenditures of hypertension in 249 small districts is 62,000 won and coefficient of variation is 30.0. Major factors of differences in hypertension expenditure is population density, marital status, household income, number of hospital per 100 thousand, medical expenses outside the jurisdiction, drinking rate, moderate and over-intensity physical activity, and hypertension diagnosis rate. The results of decision tree was that there were significant differences between regions in hypertension diagnosis rate, household income, marital status, number of hospital per 100 thousand, obesity rate, drinking rate. This study concluded that determinants of geographic variations in hypertension spending are not only health resources and socioepidemic characteristics but health behaviors.

The purpose of the research was to analyze the characteristics and the process elements which appeared to the process of designing experiment for biologists and gifted students in science. Four biologists and thirty-two gifted students were participated in this study. The findings indicated that (a) the researcher figured out the process elements could constructed in fifteen elements such as confirming questions, arrange materials, consideration for experimental subjects, searching variables, eliminating variables, selecting variables, planning operation of variables, planning control environmental variables, planning control biological variables, planning the methods of observation and assessment, planning the methods of collecting data, planning the interpretation of data, planning the repetition of experiments, planning the repetition of assessment, safety regulations as well. The biologists concentrated in the particular process elements related with variables, since the science-gifted students concerned the performance whole process elements themselves without deeper consideration, (b) the characteristics of biologists and science-gifted students in the process of designing experiment were as follows; 1) biologists and students showed the process elements which include the domain specific process skills as well, 2) biologists accurately conducted the designing experiments processes with repetition of specific process, since students designed experiments conventionally, and 3) biologists possessed the domain specific skills and know-how about their experiments, but students did not. The results show that the programs of designing experiment activity should be constructed with the process elements which were concentrated by biologists, should provide feedbacks to design experiment more accurately, and should be developed with concern of the process skills and know-hows of biologists.

While periodic marketing systems have lasted for more than hundreds of years in Korea, the weekly (periodic) markets have emerged since the latter half of the 1990s in the densely populated urban areas. In Jinju, weekly markets are opened on eight densely populated area: Ehyeon Wellga Apt.(Monday market), Gumsan Apt.(Tuesday market), Juyak Hanbo Apt.(Wednesday market), Chojeon Apt.(Thursday market), Manggyeong Hanbo Apt.(Thursday market), Pyeonggeo Dulmalhanbo Apt.(Friday market), Gajoa Jugonggreenville Apt.(Saturday market), and Gaho Apt.(Saturday). The merchants of Jinju's weekly markets can be classified into three groups as follows: the migrating specialized(full-time) merchants, who sell fruits, fish, and other daily necessities: the farmer part-time women merchants in the sixties or in the seventies, who sell the agricultural products that they themselves have grown around the rural areas; and the vendor merchants, who sell mostly dduk-bok-ki, eo-mug(odeng), and other fast food. The origin and persistence of periodic markets are explained in terms of the concepts of central place theory, the economic/comparative advantage of periodic markets, and the traditional organization of time and inertia.

In this research, the distribution of Platinum Group Elements (PGEs) at roadside dust in Daejeon, Korea was examined using an ICP-MS (Inductively Coupled Plasma-Mass Spectrometry) technique. For the quality assurance of the determination, method validation based on its accuracy and precision was conducted using SRM (Standard Reference Material). It was found that the relative errors of Pt, Pd, and Rh against each SRM value were -0.7%, -10.0%, and -20.4%, respectively, while relative standard deviations for three elements were less than 10%. The concentrations of Pt, Pd and Rh in roadside dust averaged as $17.4{\pm}9.2{\mu}g/kg$, $283.6{\pm}20.5{\mu}g/kg$, and $7.3{\pm}2.8{\mu}g/kg$, respectively. The concentrations of Pt and Rh have significantly higher distribution patterns in the dust at roadside and underground parking lot than those in soil of the background or other urban area. The correlation analysis between concentrations of PGEs in roadside dust indicates that the distribution of Pt and Rh concentration were strongly affected by automobile sources.

The preventive effect of Lentinus edodes extract (LE) against constipation was studied in rats. Rats were pretreated with LE contained in drinking water at the concentration of 10%, 20% and 40% over 30 days. Constipation was induced by subcutaneous injection of loperamide (4 mg/kg/day) 3 days prior to sacrifice. Treatment of loperamide resulted in decreases in the number and wet weight of fecal pellets, and increase in the number of fecal pellet in the distal colon and cecocolon weight. In contrast, the number and wet weight of fecal pellets were increased, and the number of fecal pellet in the distal colon and the cecocolon weight were decreased in LE-pretreated groups compared to the loperamide-treated group. Blood parameters such as white blood cell, red blood cell, hemoglobin, hematocrit, platelet, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration, and serum alanine transaminase, aspartate aminotransferase and alkaline phosphatase activities, and blood urea nitrogen and creatinine values were not significantly different between the groups. In addition, LE (0.5 mg/mL) increased spontaneous contractile activity, which was reduced by atropine or loperamide in isolated rat ileum. Theses results suggest that the improvement of constipation symptoms in LE-pretreated rats resulted from a stimulatory effect of LE on intestine contractile activity.

Retention ponds have been dug along some of the motorways to control water flow during rainstorms and to minmize environmental pollution. A retention pond located at Les Ardilleres about 20km South of Orleans along the A-71 motorway has been selected to evaluate the effectiveness of such a pond as a trap for heavy metals. Based on the "index of geoaccumulation" and the "enrichment factor" normalized to Fe introduced by Muller in 1979 and by Helz in 1976, respectively, the degree of contamination by heavy metals for the roadside soil and the settling particles was evaluated. As expected, the contamination was very severe in the roadside soil, while it was not so great in the settling particles. Using these methods, cadmium anomaly was traced in the settling particles of the retention pond, their occurrence being attributed partly to natural and partly to anthropogenic pollution. The estimated input of heavy metals associated with settling particles to the pond was 0.9 g/day Pb, 2.1 g/day Zn and 6mg/day Cd. A tentative mass balance of Pb and Zn originated by motor vehicles suggested that only 5 to l1% of heavy metals deposited on the surface of the motorway is carried to the retention pond by runoff water ; suggestions are made to improve their efficiency.ve their efficiency.

Purpose: This study examined the clinical success rate of Mg titanate implants (M Implant system, Shinhung, Korea), which employ a Mg coating method, by evaluating the marginal bone loss and implant stability using radiographs and Osstell$^{(R)}$, over a 1 year. Materials and methods: The locations of the implants placement were divided into 4 areas; the maxillary and mandibular premolars and molars. In the maxilla, 8 and 9 implants were inserted in the premolar and molar areas, respectively. In the mandible, 11 and 51 implants were inserted in the premolar and molar areas. Marginal bone loss and ISQ of all implants (79) were measured after insertion, mounting the prosthetic appliance, and 1, 3, 6, and 12 months after loading. The marginal bone loss was measured from the radiograph using XCP bite, which was customized, and the implant stability measured using Osstell$^{(R)}$. Fisher's exact test (${\alpha}$=.05) was used to compare the success rates of each region. Results: The mean marginal bone loss for the upper and lower jaws were 1.537 mm and 1.172 mm. The mobility showed a non-significant reduction or increase according with time. The success rates were accounted for 94.12% and 98.39% in the upper and lower jaws; the premolars and molars were accounted for 100% and 96.67%. The two cases of early failure resulted from failure of primary stability during implant insertion. The late failures were not observed for 1 year after adding a loading to the implants. Conclusion: The Mg titanate implant showed good primary stability and good clinical results in both healing and function.

A total of 122 rabbits (40 males, 51 females, 25 castrated males and 6 spayed females; age range: 3 months to 11 years; weight range: 0.8-3.4 kg) were admitted to Veterinary Medical Teaching Hospital of Chungnam National University from January 2012 to February 2013. The syphilis rapid test was positive in 21.3% of rabbits, with a significant difference in the rates of positivity between male versus female rabbits and rabbits younger than 1 year versus older than 1 year of age (both p < 0.01). Skin lesions were detected around the lips (59.1%), nose (56.5%), genitalia (50.0%), anus (40.9%) and eyelids (18.2%). Coexisting skin lesions were found on the nose and lips (26.0%); anus and genitalia (21.8%); lips, anus and genitalia (17.4%) of rabbits. Twenty-two rabbits with skin lesions were subcutaneously treated with Penicillin G (48,000-84,000 IU/kg, Green cross, Korea) every 7 days for three or four weeks. All skin lesions were disappeared after Penicillin G treatment. In conclusion, a rabbits with skin lesions and serological test positive for syphilis should undergo prompt treatment and not be used for breeding.
