In Danyang area, various geological structures as well as various lithology and strata are well developed, which are useful for studying paleo-environment and structural movements, and also typical karst landforms, wethering landforms and river landforms. If geologically and geomorphologically valuable resources are used in terms of geotourim perspective, it is expected that revitalization of regional economy through diversification of attracting factors and employment creation of local people. Danyang has many excellent geological resources for geological field trip, they can greatly contribute to the development of geology such as expanding the base of geology and cultivating successive generations. In this study, we have evaluated newly discovered sites and previously excavated resources based on academical and educational values. By using these geological and geomorphological resources, we suggest three geotrail courses as follows. First, Geo-trail A is mainly focused on geological structures (Route A: Jeong Hwan Route), where we can learn geological deformation and movement through various brittle and ductile deformation structures. Second, Geo-trail B is mainly focused on stratigraphic importance (Route B: Soon-Bok Route), which emphasizes on various rocks, strata and contact relationship. Third, Geo-trail C is mainly focused on geomorphological landforms and landscapes (Route C: Satgat Route), which provide information about different geomorphological landforms and the interaction between different geological agents. In order to operate these geotrail courses efficiently, installation of explanation boards and view points, cultivate local commentators, and visitor centers and experience programs should be properly prepared together.
Purpose : The purpose of this study was to analyze activities and satisfaction of volunteers for hospice care. Methods : We used 271 reports of hospice care and 20 questionnaire of activities and satisfaction of volunteers for hospice care from volunteers of in a community. Window SPSS-PC was used for the data analysis and the statistical method used were the descriptive statistics, t-test, ANOVA and Pearson's correlation coefficient. Results : 1) The highest score of activity was emotional area and the next activities was physical area. 2) The degree of emotional area (t=4.94, P<.05) and spiritual area (t=3.80, P<.05) was influence by religion of volunteers. 3) The mean score of satisfaction was 3.61. 4) There was correlation between duration of activity and death experience (r=.558, P<.05), emotional care (r=.698, P<.01), spiritual care (r=.474, P<.05), satisfaction (r=.651, P<.01), and the between physical care and family care (r=.559, P<.05), and the between spiritual cue and family care (r=.512, P<.05), and between emotional care and satisfaction (r=.536, P<.05).

Molecular markers, as an efficient selection tool, have been and is being used for practical breeding program in chili pepper (Capsicum annuum L.). Recently, a lot of researches on inheritance and genetic analysis for quantitative traits including capsaicinoids, carotenoids, and sugar content in pepper are being performed worldwide. It has been also reported that QTL mapping is a necessary tool to develop molecular markers associated with the quantitative traits. In this study, we suggested a new method to construct a pepper genetic map using SNP (HRM) markers generated from NGS resequencing of female and male parents. Plant materials were C. annuum 'NB1' (female parent), C. chinense 'Jolokia' (male parent), and their $F_2$ population consisting of 94 progenies. Sequences of 4.6 Gbp and 6.2 Gbp were obtained from NGS resequencing of 'NB1' and 'Jolokia', respectively. Totally, 4.29 million SNPs between 'NB1' and 'Jolokia' were detected and the 1.76 million SNPs were clearly identified. Among them, total 145 SNP (HRM) primer pairs covering pepper genetic map were selected, and the 116 SNP (HRM) markers of them were located on this map. Total distance of the map, which consisted of 12 linkage groups and matched with basic chromosome numbers of pepper, was 1,167.9 cM. According to the mapping result, we concluded that our mapping method was suitable to construct a pepper genetic map fast and accurately. In addition, the genetic map could be directly used for QTL analysis of traits different between both parents.
Daecheong Reservoir has suffered eutrophication and water-blooms by blue-green algae from initial impoundment, and algae alert system (AAS) was introduced in 1997. The purpose of this study was to investigate the effect of rainfall and hydrological factors in increase or decrease variability of green-tide and prolonged AAS, studied and analyzed the current situation of AAS has been operating for 19 years (1997~2015) in Daecheong Reservoir. The total issued number of AAS was 46 times, the most frequent period in August and September were 22 times (752 days) and 16 times (431 days), respectively, it accounted for 82.6%. Many number and frequency during this period were significantly associated with rainfall, various discharge and water level. Rainfall and hydrological events are associated with the rainy season of monsoon-Changma and the typhoon, it was concentrated in June~September, total rainfall in this period accounted for 69.9% of the annual rainfall. An increase in inflows was dependent on the intensity, frequency and the amount of rainfall. Accounted for 68.4% of the total annual inflow, it was a time when the most rapidly changing hydrological variability in the reservoir. The total outflow was closely related to rainfall, and compared the distinctive characteristics of hydropower generation and watergate-spillway discharge. In addition, the upreservoir zone of Daecheong Reservoir could be vulnerable to green-tide by regulating discharge of the upstream dam. The issue of AAS was strongly related to the with and without of watergate-spillway discharge. The watergate-spillway discharge had a total of 25 times, it was maximum 17 days from July to September in the year. And the opening times and each duration of the watergate were 1~4 times and the range of 3~37 days, respectively. When the watergate opened, the issue of AAS was maintained to 13 years and the movement of water bodies and green-tide was great about five times than that of non-open, had a profound effect on prolonged AAS within reservoir. In Daecheong Reservoir, Chusori (CHU) area of the So-ok Stream was still showing serious symptoms green-tide levels in the summer, but Janggye (JAN) waters of the main reservoir was pointed out that more important. AAS will be operated by an absolutely consider the rainfall and hydrological effects around the watergate-spillway discharge. The measures of green-tide will be included in the limnological studies more suited to the characteristics of the watershed and reservoir of the our country. Finally, from now on, we will prepare the systematic management and guidelines for vulnerable zone water-blooms that are the source within the reservoir before the monsoon rather than waiting for the arrival of green-tide on the operating stations of AAS.
Applying livestock manure compost to soil can enhance soil fertility and crop productivity. However, little information is available on the effect of continuous application of manure compost on crop growth in Korea. The object of this study was to investigate the residual and continuous application effect of chicken manure compost on chinese cabbage yield and soil chemical properties. The experiment was conducted in the pot ($0.5\;m^2$) without bottom buried in the soil and set up in a completely randomized design with three replication. The treatment consists of chemical fertilizer with nitrogen (NPK, $N-P_{2}O_{5}-K_{2}O$ 320-78-198 kg/ha) and without nitrogen (PK, $N-P_{2}O_{5}-K_{2}O$ 0-78-198 kg/ha), and chicken manure compost at a rate corresponding to 320 (COM1) and 640 (COM2) kg N/ha. This experiment was carried out for three cropping seasons with chinese cabbage. Chemical fertilizer, NPK and PK, was applied every cropping season. In the first cropping season, compost was applied in nine pots (COM-A). In the second cropping season, compost was applied in the six pots of COM-A (COM-AA) and in three pots of COM-A compost was not applied (COM-AN). In next cropping season, compost was applied in the three pots of COM-AA (COM-AAA) and in the other three pots of COM-AA compost was not applied (COM-AAN). COM-AN pots remained without compost application in the third cropping season (COM-ANN). Yields of chinese cabbage of COM1-AAA and COM2-AAA were reached 78 and 96% as compared with NPK, and nitrogen utilization rate was about 85% (COM1-AAA) and 97% (COM2-AAA) as compared with NPK Residual N uptake rates during the second and third cropping season after compost application at the first cropping season were 49.7 (COM1-AN) and 35.6% (COM1-ANN) in COM1, and 56.9 (COM2-AN) and 37.4% (COM2-ANN) in COM2 compared with NPK treatment After three cropping seasons, soil pH and contents of available phosphorus, exchangeable potassium and soil organic matter were increased with continuous application of chicken manure compost.

This study was carried out to classify the streams at rural watersheds by characteristics of water quality. The water quality data of 319 steams at rural watersheds in Korea were selected. Multivariate analysis was used for this purpose. The cases were divided into 5 types, and then factor analysis and cluster analysis were done. The characteristics of water quality of rural watersheds can be showed more than 40% of total water quality by first factor(organic matters and nutrients). The cluster analysis of extracted factors using factor analysis was carried out. The results showed that the Case 1 and Case 2 were classified 4 communities, Case 3 was classified 5 communities and Case 4 and 5 were classified 3 communities. Among 5 types cases, to classified the steams of rural watersheds, Case 4 - 7 water quality items - was selected as a desirable case. Many kinds of statistical analysis can be used to classify the streams of rural watersheds. Our results showed a good example to evaluate the water quality properties in Korean rural watershed.
Cerebral microvessel endothelial cells that form blood-brain barrier (BBB) have tight junction for maintaining brain homeostasis. Occludin, one of tight junction protein, is crucial for BBB function. $H_2O_2$ induced occludin changes and effects in bovine brain BBB endothelial cells were examined in this study. The decrease of transendothelial electrical resistance (TEER) by $H_2O_2$ was due to disruption of occludin localization. Cytotoxicity test revealed that $H_2O_2$ did not cause cell death below 1 mM $H_2O_2$ within 4 hr. $H_2O_2$ caused intermittent disruption and loss of occludin at tight junctions and occludin disappeared with dose dependent manner from tight junction in confocal laser microscopy. But Western blot revealed that the total amounts of occludin increased by $H_2O_2$ administration. Transmission electron microscopy revealed that the ultrastructure of tight junction was not changed by $H_2O_2$. These data suggest that functional disruption of BBB by $H_2O_2$ was due to the localized loss of occludin in tight junction, but the expression of occludin increased in order to compensate the disrupted function in BBB.
Purpose : Vesicoureteral reflux (VUR), which can result in renal failure in children, is expected to resolve spontaneously in mild cases, but severe cases require surgical correction, posing dilemma in deciding the right measures in some cases. Therefore, to delineate the factors affecting spontaneous resolution of VUR and to apply them in assessing the prognosis, we reviewed the patients with VUR who had been treated medically. Patients and Methods : 32 children (49 renal units) with reflux who had been admitted during the 5-year period from Jan '92 to Dec '96 were classified into 4 groups (Resolved, Improved, Unchanged, and Worsened) and analyzed. Results : 1) 25 were boys and 7 girls. The age at diagnosis ranged from 13 days to 9 years (mean $24.6{\pm}11.4$ mo) 2) Among 49 refluxing ureters, 4 were below 1 me of age,21 between 1 me to 1 yr, 16 between 1 yr to 6 yr, 8 beyond 6 yr. Two belonged to Grade I, 16 to Crade II, 17 to Grade III, 12 to Grade IV, and 2 to Grade V. 3) Spontaneous resolution rates of reflux were 100, 81, 47, 8, 0$\%$ for each Grade, respectively. Resolution plus improvement rates in Grade III and IV were 71 and $50\%$, each. 4) Resolution rates in relation to the age at diagnosis were $100\%$ for below 1 mo, $48\%$ between 1 mo to 1 yr, $56\%$ between 1 to 6 yr, and $13\%$ beyond 6 yr. 5) Of 15 unilateral refluxing ureters, 14 ($93\%$) resulted in resolution. Of 34 bilateral refluxing ureters, 11 ($32\%$) resolved spontaneously 6) Resolution occurred within 1 year in 20 units of 24 renal units in regular follow-up. Conclusion: The lower the initial grade and the younger the patient, the sooner the reflux resolved. Resolution was better when VUR was unilateral than bilateral. Long-term regular follow-up is essential because even the cases falling in Grades III and IV have high rates of spontaneous resolution and improvement with medical treatment.

This study investigated the initial pH measured at 15 min post-mortem, ultimate pH, water holding capacity (WHC), and color of meats obtained from five lines of Korean native chicken (KNC) for the development of breed for high-quality meat. In addition, the effect of sex was examined. In total, 595 $F_1$ progeny (Black [B], Grey-Brown [G], Red-Brown [R], White [W] and Yellow-Brown [Y]) from 70 full-sib families were used. Chickens were slaughtered at 20 wk of age and the measurement traits of all breast and thigh meats from 595 chickens were analyzed. The initial pH at 15 min post-slaughter of the breast and thigh meats was affected by the line and sex of Korean native chicken (P<0.05). However, there was no line and sex effect on ultimate pH and WHC of the breast and thigh meat except that the ultimate pH of thigh meat had line effect. Except for the $L^*$ value of breast meat, the meat color was significantly affected by line and sex (P<0.05). The ultimate pH showed consistently negative correlation with the $L^*$ value and positive correlation with the $a^*$ value in breast and thigh meats. Based on the results, we concluded that the line W in male chickens and the line G and W in female chickens may be good candidates for the selection to develop breed for high-quality meat because these lines showed property of high initial pH or/and ultimate pH.
