With developments in science and technology and improvement in living standards, human life expectancy is steadily increasing worldwide. For effective healthcare, it is necessary to check health conditions according to individuals' behavior and acquire prior knowledge on possible diseases. In this study, we classified the diseases that are major causes of death in Korea by referring to data provided by the Korea National Health and Nutrition Examination Survey. We selected indexes that could be used as indicators of major diseases and created the LCBB-SC. In the LCBB-SC, the data are systematically subdivided into related fields to provide integrated data related to each disease and to provide an infrastructure that can be used by researchers. In addition, by developing a web interface allowing for self-symptom assessments, this resource will be beneficial to people who want to check their own health condition using a list of diseases that might be caused by their behaviors.

This study is a study on the satisfaction of the living conditions of the residents of Chungcheongnam-do, and the analysis data was based on the results of the Chungcheongnam-do social survey conducted in 2020 by Statistics Korea. The results of the analysis on the satisfaction of the living conditions of the residents of Chungnam Province are summarized as follows. The level of satisfaction with the quality of life of the living environment, which is a personal characteristic, was 5.92 out of 10 for the degree of satisfaction with one's life, and 6.28 out of 10 for the overall value of the work one is doing. The overall life satisfaction of the region (city and gun) was analyzed as 5.81 out of 10, indicating that the satisfaction of Chungnam residents was more than average. In addition, satisfaction with the residential housing environment was analyzed with the highest frequency and ratio of 43.5%, with 226 people being slightly satisfied. Satisfaction with facility use was also slightly higher in 231 people, showing 44.5% response rate, and slightly higher in women than in men. This study is meaningful in that it provides basic data such as policy implications for improving the quality of life by grasping the social interests related to the quality of life and the subjective consciousness of the people of Chungnam.

A Ubiquitous City (U-city, Smart City) is one that ties information communications technologies (ICT) into many facets of city construction, thereby implicitly intending to function as a smart city that aims to be efficiently managed as well as provide an enhanced standard of living for its residents. Laws related to the construction of such ubiquitous cities point to integrated city management centers, intelligent facilities, and U-City infrastructure, among others, as central components of U-Cities, but do not provide a standard for these structures. Consequently, building of U-Cities by local governments are based on arbitrary judgments constrained the myriad of practical limitations that they face. Such ambiguity brings to light the need to find ways to improve the quality of these efforts. The first and second stages of this research examine the status of the components of a U-City -ubiquitous planning, technology, infrastructure, and services - and undertakes a comprehensive review thereof, with evaluation criteria formulated on the characteristics of stability, connectivity, goal-orientation, and development potential. In the research's third stage, a realistic and detailed evaluation index by which U-Cities can be renewed, demonstrated, and applied (???) is introduced in a step-by-step fashion, which will allow for local governments to properly assess the standard of their U-City in relation to the realities of the locality. Through the research result, it is expected that the index will become a part of the continued development and advancement of the "smart" character of an autonomous U-City at the local scale, and contribute to the overall revitalization of the U-City.

This study analyzed the relationship between spatial characteristics and heat waves in the distribution area of the elderly population in Changwon, Gyeongsangnam-do. For analysis, the Statistics Census data, the Ministry of Environment land cover, Landsat 8 surface temperature, and the Meteorological Agency's heat wave days data were used. The spatial characteristics of the distribution of the elderly population was classified into 5 types through K-mean cluster analysis considering the land use types. The characteristics of the elderly population by spatial type were higher in the urbanized type(cluster-3), but the proportion of the elderly population was higher in the agricultural and forest area types(cluster-1, cluster-2). In the characteristics of the surface temperature and the heat wave days, the surface temperature was the highest in the urban area, but heat wave days were the highest in the rural area. As a result of analyzing the heat wave characteristics according to the spatial type of the distribution area of elderly population, cluster-2 with the largest area in agricultural areas was highest at 15.95 days, and cluster-3 with a large area in urbanized types was the lowest at 9.41 days and 9.18 days. In other words, the elderly population living in rural areas is more exposed to heat waves than the elderly population living in urban areas, and the damage is expected to increase. The results of this study could be used as basic data to prepare various policy measures for effective management and prevention of vulnerable areas in summer.

Purpose: This descriptive study investigated the relationship between death awareness and life ethics awareness, according to life stress, among students in the department of paramedics. Methods: General characteristics were identified using means and frequency, and the differences between the two military models were analyzed using the χ²-test and t-test by dividing them into lower and higher groups based on the mean life stress score (99.76 points). Results: Those with high life stress had higher death awareness than those with low life stress at 114.11 points. In contrast, those with low life ethics experienced more severe life stress with a score of 145.61 points (t=-2.609, p=.010)(t=-2.953, p=.003). The death recognition attitude and bioethics according to the degree of living stress-showed a significant correlation between the low and high groups (r=.188, p=.043) (r=.201, p=.042). Conclusion: Paramedic students require education on how to cope with life stress. However, access to education is limited to people living in modern times. As a potential solution to this problem, observing videos on the Internet is recommended. Moreover, we suggest accessing Internet and smart phone applications for advertising/educational purposes.

The aim of this study is to reinterpret the image on a Korean tradition known as Bang-wee-shin-sang (an image of direction deity), and to revive the image into Jikimee (the guardian). In particular, this research re-analyzed the image and the symbol of Bang-wee-shin-sang and effectively designed the tradition to fit the modern living space. The theoretical study is to explore why it is necessary to redesign Bang-wee-shin-sang to accommodate modern living after examining the background and origin of typical Korean traditions such as Four Deity painting, Chinese Zodiac, and Four Kings' Painting. As a previous study, we examined the procedures of making Jikimee which was based on artists' works that utilized historical artifacts. The study indicated that Bang-wee-shin-sang is a vital resource to disseminate the unique characteristics of Korea and its tradition which played a role in linking the past and the present. Consequently, it is discussed that the utilization of modernized Jikimee in smart environment must be supported by foundation of academic system, the effort of academic and research link, and government funding policy.
