  • For the inaccessible area where the field verification is unable, it is difficult to obtain the ground control points (GCPs) or the acquired GCPs may be inaccurate. In general systematic geometric correction is achieved by utilizing orbit ephemeris and three axis attitude data of the satellite. however, this method results to poor accuracy of the imagery's absolute coordinates. To improve the absolute accuracy as well as the relative accuracy, we added the accessible region into the inaccessible area. We obtained GCPs in the accessible region by the fast static GPS survey and made geometric corrections with these biased GCPs. Because the biased GCPs show a pattern of coordinate errors, we analyzed this tendency to track the estimated errors in the inaccessible area.

  • Purpose: This study aimed to investigate the status and factors associated with self-management behavior (SMB) of patients with type 2 diabetes (T2DM) in a border area of southwest China. Methods: A cross-sectional study was conducted with T2DM patients in Dali, China. The participants filled in the questionnaires including demographic and disease-related characteristics, psychosocial status, resources of DM knowledge, knowledge of DM care, competency in DM care skills, the Chinese Diabetes Management Self-Efficacy Scale (C-DMSES), and the Chinese Summary of Diabetes Self-Care Activities (C-SDSCA). All the data were analyzed with SPSS version 26. Multiple linear regression analysis examined associations between predictors and SMB. Results: A total of 470 valid questionnaires have been collected. The score for overall SMB was 50.71± 11.99; 19.6% of patients were at a good level, 48.3% were moderate, and 32.1% were poor. The significant factors that influenced SMB included self-efficacy (β= 0.37; p< .001), competency in DM care skills (β= 0.22; p< .001) and lacked in the treatment confidence (β= -0.09; p= .023). Conclusion: The level of self-management among T2DM patients in this area was medium-low state. For future studies, our findings suggest that self-efficacy, competency in DM care skills, and treatment confidence should be considered essential factors in improving the self-management behavior of T2DM patients in the border area of southwest China.

  • Purpose - This study used empirical methods to investigate the consciousness structure of vendors in the S marketing area, which is a commercial revitalization district in the country, and examined its effect on their business activities. Based on the results derived through the performance of an actual proof analysis, this study aims to facilitate the promotion of changes in the consciousness structures of traditional market vendors, with a view to allowing them to adapt to the current economic realities in the country. Further, this study aims to provide suggestions that would improve the efficiency of the commercial revitalization program of the government. Research design, data, and methodology - This study examined all the stores in the S marketing area using a questionnaire survey conducted over three weeks beginning on July 4, 2012, and involved the performance of a data analysis on 1,859 samples. The questionnaire consisted of two parts. The first part addressed the market revitalization and the second part addressed the store management strategies. Questionnaire responses were calibrated based on a Likert scale. Statistical analysis was conducted using PASW version 18.0. Results - The results of the analysis of the consciousness structure of merchants in the S marketing area have led to the discovery that they have a medium level of satisfaction with market revitalization. There was a difference in the perceptions of the concept of store management between merchants and customers. Merchants have poor strategies for store management, which do not go much beyond an imitation of the practices of large domestic discount stores. Conclusions - The appearance of big discount stores and the accompanying changes in people's consumption patterns have led to a decline in local market areas. The government has sought new ways to secure autogenic power for local markets. To create regional economies, the government enacted a revised "Law for creating traditional markets and shopping streets" in 2010 and introduced a commercial district revitalization program. This program, which originally supported only the S marketing area, has subsequently expanded into neighboring shopping districts so that the whole of the regional market can be revitalized. However, since the revitalization of the traditional market and the government support required for it were mostly limited to facilities, the result has not proved to be effective. Although there are several reasons why the government investment was characterized by poor efficiency, traditional market vendors' consciousness structure, which did not adapt well to the vagaries of time and its consequent changes, was a major cause. Only when vendors have a true merchant spirit can they have a real service focus that will enable them to clearly understand the distribution organization. This will have the effect of bring about complete customer satisfaction and will ensure the survival and development of traditional markets.

  • Poor dietary habits and inadequate nutrient intakes are of concern in the elderly, even it is worse in rural areas. In the present study, we conducted the anthropometric measurement and the dietary intakes including macronutrients, minerals and vitamins to assess the nutrient intakes and nutritional risk in elderly people in rural kyungpook province in South Korea. Subjects (n = 168, mean age, 67.3 yrs) were interviewed using d general questionnaire and 3 days of 24-hours recall for dietary intake. Nutrient intakes were analyzed using CAN-pro soft program and compared to Korean RDA and nutrition reference values (NRV). The anthropometric measurement showed that the weight and the height of the subjects in the rural area were below the average of the same age of Korean elderly people. The energy and protein intakes were 85% and 90% of Korean RDA, respectively. The intakes of lipid, cholesterol and dietary fiber were 62%, 40% and 22% of NRV for Korean adults. Main sources for protein and lipid intakes came from the vegetable sources and this pattern was more prominent in female elderly people. Ca intake was half of Korean RDA (56%), while P intake was 132% of Korean RDA. For the antioxidant trace mineral (Fe, Cu, Mn, Zn, and Se) intakes, Fe and Zn intakes were 78% and > 103% of Korean RDA. Cu, Mn and Se intakes were > 113%, > 275%, and > 185% of Korean NRV. Thiamin, niacin and vitamin C intakes were above Korean RDA, but the intakes of vitamin A and riboflavin were 88% and 63% of Korean RDA, respectively. On summarizing the results of the present study, the elderly people in rural area consume less lipid, cholesterol, Ca, and dietary fiber. Ca intake is lower, while P intake is higher, and this would be the potential risk for bone health. Also, Na intake was high, which can be the potential risk for the cardiovascular disease prevailance. Vitamin intakes were fairly good status, excepting riboflavin. Antioxidant mineral intakes were much higher than Korean NRV, unexpectedly. The results suggest that the elderly people in rural area have inadequate intakes of protein, lipid, dietary fiber and Ca, which mainly should be supplied from animal products. Recommendations to increase diet variety would be emphasized for this nutritionally poor-conditioned subjects, specially including animal food products and high dietary fiber food.

  • Atypical facial pain (AFP) is a type of facial pain which does not fulfill any other diagnosis. It has several features such as no objective signs, no obvious explanation of the cause and poor response to treatments. We report a case of a female patient with AFP on the left maxillary area. The pain was increased by cold innocuous stimulation and thermography showed that the temperature on the painful area was significantly decreased. The pain was successfully alleviated by stellate ganglion block (SGB). Therefore, SGB can be effectively used to treat AFP.

  • For tile hydrogeological data of the National Groundwater Monitoring Wells(NGMW), a statistical analysis is made to reveal aquifer characteristics of the country. Results of the pumping and recovery test are classified into 4~5 types by the pattern of drawdown and residual drawdown curves. The analysis of aquifer characteristics shows that the hydraulic conductivity of alluvial aquifers is greater than that of fractured-rock aquifers. The hydraulic conductivity of alluvial aquifers slightly increases as the distance to the discharge area decreases. 77.5% of the NGMWs, where the distance to the discharge area is more than 100m, shows the constant head boundary. This result suggests that the fractured and the alluvial aquifers are fairly interconnected, and water can be supplied from one aquifer to tile other where pumping tests are performed. It is analyzed that the wells showing the impermeable boundary are influenced by small scale of aquifers, poor aquifer transmissivities, and impermeable layers.

  • Electric shock is the accident caused by the current through a person or animal's body. That is characterized by the physiological effects. In this paper, we evaluate performance of protection against electric shocks for TT and TN grounding systems which are used by a low voltage consumer nowadays. The performance of protection against electric shocks for TT grounding system is very excellent in equipotential area of the third class grounding, but the performance is poor outside the equipotential area. The performance of protection against electric shocks for TN grounding system is excellent because the potential difference is less than 50V. Accordingly, the performance of protection for TN grounding system is good as compared with that for TT grounding System.

  • Since Jeju island has depended a water resource on the underground water because of a poor development of the surface flow, Jeju island is in need of the surface resource development to prevent the future shortage of the underground water due to excessive development and use of it. The study shows that the SWAT model(continuous rainfall-runoff model) is applied to estimate the outflow in the drainage watershed area, where it has been urbanized through the change of the land, such as a tourism development, cultivation, housing, and impervious layer road development. Near watershed area in Jeju island, weather and topographical SWAT input data were collected, and compared the outflow change of past and present.
