  • 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.

  • An assessment of typhoon intensity predictability of numerical models was conducted to develop the typhoon intensity forecast guidance comparing with the RSMC-Tokyo best track data. Root mean square error, box plot analysis and time series of wind speed comparison were performed to evaluate the each model error level. One of noticeable fact is that all models have a trend of error increase as typhoon becomes stronger and the Global Forecast System showed the best performance among the models. In the detailed analysis in two typhoon cases [Danas (1324) and Haiyan (1330)], GFS showed good performance in maximum wind speed and intensity trend in the best track, however it could not simulate well the rapid intensity increasing period. On the other hand, ECMWF and Hurricane-WRF overestimated the typhoon intensity but simulated track trend well.

  • This study began to classify the studies on 'culture' in the field of environmental design overall. The classifying process adopted not the approach to preselect the criteria but the phenomenological inductive approach and content analysis method focusing on environmental design in order to understand which place the environmental design had taken. As a result, following aspects were reviewed: what is the area in which the studies on culture is made under the environmental design; what is the trend of using the word 'culture' in terms of logical connection; what is the level of approach to culture from the viewpoint of search, correspondence or application stage. On the whole, followings were drawn as conclusions. First, the interest of the studies on culture has been increased with time especially in the field of interior design. Second, the word 'culture' has become to be used a lot as 'cultural', and was used together with traditional, enterprise and material. Lastly, culture was studied at a starting point by and large. Although the papers, the objects of this study, are confined to five kinds of journals, the analysis of them is helpful to preestimate the trend of studies on culture because they have propensity to lead the international professional academic world.

  • The way we live on our own is distinguished from those of the other countries while the society changes rapidly globalized with the flow. It is called housing culture when culture is discussed in dwelling, what contains living. With the beginning of building Mapo Apartment in 1962, apartment has become the most popular type of housing and currently is provided more than 50% of housing unit in Korea. Even though it has been criticized for a problem of standardization in its form and social issues, its provide increases in its number and its types become hilghly diversified in construction. Therefore the housing culture of apartment should be accepted as a characteristic of our society and it's time to find the identity of our housing culture and make a progress in it. Studies related to apartment are also increased in its number and diversified in its range. The purpose of this study is to go through the trend of studies related to apartment and to analyze subject and content changes according to politic, social and economic changes for the recent 10 years. The study would provide the basic research material related to apartment both to academic area and companies in the future.

  • Objectives: Analysis and understanding on the health trend of college and university students are paramount to creating healthy campus communities. We evaluated the change of health status, health behavior, and influencing factors among them in the last ten years. Methods: Using the results of the ACHA-National College Health Assessment from 2000 to 2009, we reanalyzed the trend of health condition, health behavior, and health risk factors in linear regression model. Results: In general health of college and university students, major health problem were allergy problems, back pain, and sinus infection. Academic impacts were stress, sleep difficulties, cold/flu, concern for troubled friend or family member, relationship difficulty, and internet use or computer games. Although regular exercise was decreasing among them, it were more likely to have never smoking, no sexual partner, and eating of fruits/vegetables as time passed (p<0.05, p<0.01). Obesity and sleeping difficulty were increasing, while it were less likely to have feeling very sad, feeling hopelessness, and considering attempting suicide (p<0.05, p<0.01). Conclusion: These data expand the understanding of the health needs and capacities among young adults. For Korean college and university students, it is necessary to standardize the data-collection survey to set the college health and healthy campus.

  • Purpose: This study was done to describe the research trend of nurses' job stress in Korea and abroad. Methods: A narrative literature review of nurses'job stress related literature published from 1990 to Sept. 2011 was done. A total of 691 original articles were reviewed by two independent reviewers using analysis guidelines. Finally, 261 articles (Korean 177, international 84) were selected using exclusion criteria developed by the researchers. Results: In Korea, most of the researches were in correlational survey design, using questionnaires and the tool of Kim and Gu (1984) to measure job stress. International researches were more diversified than Korean's in the research design, measurement tool, and data collection method. Especially, most of international researches focused on job related factor (number of patients, working time, etc.) and physical effects (tension, heart rate, etc.) of job stress. Conclusion: The results of the study may provide with information that can improve researches on nurses' job stress in Korea.

  • This study analyzed the Seungmu research trends published in domestic academic journals from 1978 to 2021. Seungmu, a traditional Korean dance, has been handed down for a long time and has established itself as a traditional dance representing Korea. I think that the trend analysis of Seungmu Dance can present basic data that can solidify the succession, preservation and development of Seungmu Dance, a sustainable traditional cultural heritage. I think that the trend analysis of Seungmu dance is a meaningful process that lays the foundation for the vitalization and popularization of Korean traditional dance.

  • Network management for detail analysis can cause speed decline of application in case of lack band width by traffic increase of the explosive Internet. Because a manager requests MIB value for the desired objects to an agent by management policy, and then the agent responds to the manager. Such processes are repeated, so it can cause increase of network traffic. Specially, repetitious occurrence of sending-receiving information is very inefficient for a same object when a trend analysis of traffic is performed. In this paper, an efficient SNMP is proposed to add new PDUs into the existing SNMP in order to accept time function. Utilizing this PDU, it minimizes unnecessary sending-receiving message and collects information for trend management of network efficiently. This proposed SNMP is tested for compatibility with the existing SNMP and decreases amount of network traffic largely
