  • Purpose: The objective of this study was to provide a trend analysis of the prevalence of diabetes relative to the socioeconomic, lifestyle, and physiologic risk factors among Korean adults aged over 30 years for a 10-year period using data from the Korean National Health and Nutrition Examination Survey. Methods: Prevalence difference and the slope index of inequality were calculated for each risk factors using binomial regression by considering the repeated cross-sectional features of the data. The prevalence ratio and the relative index of inequality were calculated using log-binomial regression. Linear trend tests were performed using SAS 9.2. Results: Crude prevalence of diabetes increased over the 10-year period, and was higher for men than for women. It was very high for adults 60 years or over, consistently increasing over time. The prevalence among unemployed men, women with higher level of stress, women with hypertension, and adults with serum triglyceride levels over 135 mg/dL increased over the 10-year period in comparison with the respective control group. Conclusion: Considering the rapid economic development and associated lifestyle changes in Korea, action should be taken to control the prevalence of diabetes by both preventing and consistently monitoring these identified risk factors using a public-health approach.

  • Since the 1980's, telephone surveys have been widely used in the world due to a rapid spread of fixed telephones and the development of a variety of sampling techniques. Telecommunications technology has rapidly developed since the early 1990's, and the number of mobile phones grew rapidly in most countries. Also, it has dramatically increased over the last few years. With the growth of households that abandon fixed telephones and move to a mobile only status, fixed telephone household coverage rates are currently decreased in many countries. In this paper, we take a look at the changes and trends in fixed telephone households coverage rates in the European Union, Asia including South Korea, and North America, and deal with the coverage problems in telephone surveys to be faced even in Korea.

  • Recently, the assisted living facilities for the elderly are increasing due to the facts, such as rapid increasing ratio of old people, rising incomes and the changing concepts towards family relationship. For the elderly, there is a need to re-examine how environment can incorporate design concepts which enhance accessibility and adaptability. For this survey each seven cases in Korean & American facilities were examined and also 120 copies of a questionnaire for the elderly who are above 60 were analysed. This survey revealed that; 1. The consciousness of the majority elderly was favorably aware of the assisted living facilities for the elderly by a social phenomenon. 2. At a response of the scale for the living unit, majority subjects preferred to live in size of 16${\sim}$20 pyung. 3. Subjects preferred not only clean and modern atmosphere, but also medical area and fitness room, design considerations for these points are needed. 4. Enough spaces for their hobbies and social activities, which are important factors for smooth understanding, communication and psychological remedy effect for the elderly should be provided in the facilities for the elderly. 5.Korean facilities were lack of accessibility, safety and adaptability, thus it is very important to select the suitable materials for the safety and lighting plans with regard to their physical and mental qualities.

  • Recently, DMB service markets experience a rapid change with terrestrial DMB test-broadcasting for the nation-wide coverage and paid interactive data broadcasting being offered utilizing TPEG and BIFS technologies. This warrants a reexamination of a consumers' adoption intentions for DMB service. This paper uses a survey data set to analyze DMB adoption intentions and the choice between terrestrial DMB and satellite DMB services according to preferred contents and other media usage characteristics. Empirical results show that consumer who prefer TV, music, and movie contents are more likely to adopt DMB service, whereas consumers with high intentions for HSDPA subscription are less likely to adopt DMB service. This implies that continuing development of killer application and the analysis of substitutes or complements of other media are crucial for the increase of DMB adoption intentions. It is found that the more consumers prefer sports, movies and entertainment/game and put higher values in the quality of the contents, the more likely they adopt satellite DMB service. Meanwhile, the more consumers prefer TV, drama and news contents, and are sensitive to the subscription fees, they are more likely to adopt terrestrial DMB service. Therefore, it seem that consumers' DMB adoption between terrestrial and satellite services is crucially related with types and characteristics of contents offered.

  • This study has developed an Enhanced Remote-Sensing (ERS) scale to improve the accuracy and efficiency of using remote-sensing images of residential building to predict their damage conditions. The new scale, by incorporating multiple damage states observable on remote-sensing imagery, substantially reduces measurement errors and increases the amount of information retained. A ground damage survey was conducted six days after the Joplin EF 5 tornado in 2011. A total of 1,400 one- and two-family residences (FR12) were selected and their damage states were evaluated based on Degree of Damage (DOD) in the Enhanced Fujita (EF) scale. A subsequent remote-sensing survey was performed to rate damages with the ERS scale using high-resolution aerial imagery. Results from Ordinary Least Square regression indicate that ERS-derived damage states could reliably predict the ground level damage with 94% of variance in DOD explained by ERS. The superior performance is mainly because ERS extracts more information. The regression model developed can be used for future rapid assessment of tornado damages. In addition, this study provides strong empirical evidence for the effectiveness of the ERS scale and remote-sensing technology for assessment of damages from tornadoes and other wind events.

  • As a part of acoustical design, it is often necessary to quantify aspects of an existing environment and to predict the result of adding an acoustical treatment. The most common sources of exterior noise, also termed as environmental noise,(or community noise) are traffic noise, air craft noise, industrial noise, etc. Transportation(air, road, and rail)noise is the dominant and most common source of noise exposure in residential neighborhoods, and the annoyance is its most consequential effect. The road traffic noise becomes aggravated due to the rapid increase of vehicles. It has a great effect on the dwelling environment. Therefore we investigate the characteristics and sources of the road traffic noise through grasping the status of the road traffic noise. In the present study, preceding studies investigated the noise level of urban areas in Seoul were reviewed and the noise level of urban areas in Seoul was measured at first, fifth, tenth, and nineteenth floor for two days of weekdays and two days of weekend.

  • HVDC(High Voltage Direct Current) is an underwater cable between Jeju Island and Haenam in main land and supplies approximately $50\%$ of electrical usage in Jeju Island. If there is any power failure due to HVDC, it will cost approximately 50,000 US dollars per day including Thermal Electrical Generation. Therefore it is absolutely necessary to recover the problem in rapid timely basis. Present survey method in Korea is done by scuba diver with air cylinder resulting very poor visual inspection. Other option is by only visual camera attached on miniature ROV for solely suey Purpose. This method does not includeburial depth of cable, cable position, cable condition & etc??‥‥.??? In result, current method does not generate any scientific or sophisticated data which does not allow any intelligent management decision. In conclusion, new method and new systems are needed urgently to upgrade current HVDC underwater cable survey technique in Korea to minimize the cost and time factors.

  • The research was conducted to quantify farm and household characteristics of sheep farmers, evaluate farmer access to and the effectiveness of livestock services in sheep farming areas, and examine regional constraints to improving sheep productivity and profitability in Nepal. A rapid diagnostic socioeconomic survey of 200 sheep farmers was carried out in 1996 and all four ecological regions (Trans-Himalayan, Mountains, Hills and Terai), each with a distinct local sheep breed, were represented in the survey. Six major constraints were identified: (a) poor performance of local sheep breeds, (b) a serious seasonal deficit of pasture and other feed, (c) the lack of an organized market for wool and meat, (d) poor access to agricultural credit, (e) primitive shearing equipment, and (f) an inadequate supply of drinking water for sheep. Strategies to assist farmers develop their sheep management skills, improve access and quality of support services, improved technology adaptable to local conditions and effective linkages with local carpet and meat industry are likely to overcome the constraints and alleviate persistent poverty faced by sheep farmers in Nepal.

  • BACKGROUND: The present study is an exploratory research to establish national biosafety regulation systems through a survey on the recognition of safety regulation systems for the living modified organism(LMO). METHODS AND RESULTS: We have conducted a survey on an awareness of LMO safety regulation systems in scientific working groups. The data of 235 respondents were analyzed using various statistical methods. As a result, 72.8% of the respondents were male; 27.2% were female, and 43.4% of them work in the university. A total of 33.2% of the respondents majored in general biology, and their most common job position was the laboratory safety manager. The difference of an awareness on LMO law and regulatory system was not statistically significant by either work places or job positions. CONCLUSION: For the rapid settlement and the efficient implementation of LMO safety management policy, we conclude that it is required to reduce the gap between the recognition and fulfillment of safety management. Furthermore, the mutual exchanges of information among researchers are needed with the settlement of the safety management system and the harmony of policy with improvement of the absurd regulations. The ongoing and specialized training, inspections, and the strengthening of public relations are also required along with the efforts to improve the absurd regulations.
