PURPOSE. This study aims to assess and predict lifespan of dental prostheses using newly developed Korean Association of Prosthodontics (KAP) criteria through a large-scale, multi-institutional survey. MATERIALS AND METHODS. Survey was conducted including 16 institutions. Cox proportional hazards model and principal component analysis (PCA) were used to find out relevant factors and predict life expectancy. RESULTS. 1,703 fixed and 815 removable prostheses data were collected and evaluated. Statistically significant factors in fixed prosthesis failure were plaque index and material type, with a median survival of 10 to 18 years and 14 to 20 years each. In removable prosthesis, factors were national health insurance coverage, antagonist type, and prosthesis type (complete or partial denture), with median survival of 10 to 13 years, 11 to 14 years, and 10 to 15 years each. For still-usable prostheses, PCA analysis predicted an additional 3 years in fixed and 4.8 years in removable prosthesis. CONCLUSION. Life expectancy of a prosthesis differed significantly by factors mostly controllable either by dentist or a patient. Overall life expectancy was shown to be longer than previous research.

In recent years the life expectancy of the Korean people has been increasing appreciably because of the improvement in living conditions and public health facilities as well. However, there exist considerable constraints in the measurement of Korea's mortality rate. In elaboration, there are quite a few persons who do not submit birth and death reports, thereby lowering the reliability of statistical data. The 1978-1979 life table of the Korean people is still considered the latest one. Nevertheless, a decade has passed since its publication, and the need for a better life table reflecting realities is inc-reasingly growing. Capitalizing on the annual report of demographic statistics and demographic sample survey data m 1988, I have worked out the 1986 tentative life table of the Korean people and found out the following : 1. The male life expectancy in the 1978-1979 life table of the Korean people is 62.7 years old, and that of the female sex is 69.1 years old whereas the average life expectancy of the male sex in the 1986 life table stands at 66.3 years old, and that of the female sex is 74.5 years old. The average life expectancy is up by 3.5 years old for the male sex and also, up 5.4 years old for the female sex, res-pe ctively. 2. A gap between the male and female life expectancies in the 1978-1979 life table was 6.4 years old, while that of the 1986 life table was 8.2 years old. It means the female life expectancy has increased substantially. 3. The infant mortality rate has decreased, compared with the 1978-1979 level, yet it is still above those of Japan and Taiwan. 4. The mortality rate of the middle - aged men in the forties remains high, as was the case in the 1978-1979 period.

The health status of a population is usually measured by mortality such as crude dealth rate, cause-specific mortality rate, infant mortality rate and life expectancy. However, these indices based upon mortality (i.e., quantity of life) are increasingly unsatisfactory to assess health status, especially in an aging society. In this presentation, I will discuss the followings as regards quality of life (QOL) in health science.

Purpose: The purpose of this study was to investigate the status of internet addiction, internet expectancy, and self-efficacy in elementary school students. Method: The study was carried out during the period from June 16 to July 12, 2003. The subjects in the study were 397 elementary students attending four elementary schools in Chungcheongbuk-do and Kyunggi-do. Self-rating questionnaire included general characteristics, internet addiction scale, internet expectancy scale, and self-efficacy scale. Data was analyzed using SPSS/WIN10.0 by unpaired t-test and Pearson corelation coefficient. Result: In this study, the mean score of internet addiction was 20.7. Internet dangerous group was 12.6% and internet addicticted group was 0.3%. The score of internet addiction was significantly different according to parents' concern, aversion to school life and extracurricular lecture. The mean score of internet expectancy was 27.1. The score of Internet expectancy was significantly different according to popularity among friends and easiness of making friends. The mean score of self-efficacy was 55.8. The score of self-efficacy was significantly different according to conversation with parents, enforcement of parents on learning, aversion to school life, aversion to extracurricular lecture, existence of intimate friend, popularity among friends(p=.000), and easiness of making friends. Conclusion: This study showed that prevalence of internet addiction was much lower than expected, but the score of internet addiction and internet expectancy can be different according to parents' concern and relationship with friends. Therefore parents must be concerned about their children and their school lives to prevent internet addiction.

Background: Prostate cancer (PC) is one of the leading causes of death, especially in developed countries. The human development index (HDI) and its dimensions seem correlated with incidence and mortality rates of PC. This study aimed to assess the association of the specific components of HDI (life expectancy at birth, education, gross national income per 1000 capita, health, and living standards) with burden indicators of PC worldwide. Materials and Methods: Information of the incidence and mortality rates of PC was obtained from the GLOBOCAN cancer project in year 2012 and data about the HDI 2013 were obtained from the World Bank database. The correlation between incidence, mortality rates, and the HDI parameters were assessed using STATA software. Results: A significant inequality of PC incidence rates was observed according to concentration indexes=0.25 with 95% CI (0.22, 0.34) and a negative mortality concentration index of -0.04 with 95% CI (-0.09, 0.01) was observed. Conclusions: A positive significant correlation was detected between the incidence rates of PC and the HDI and its dimensions including life expectancy at birth, education, income, urbanization level and obesity. However, there was a negative significant correlation between the standardized mortality rates and the life expectancy, income and HDI.

We measured the concentrations of air pollutants at several residential sites, roadside sites and industrial sites in Iwate Prefecture, Japan. And the concentration distributions of air pollutants were estimated by atmospheric dispersion model using air emissions data. Based on those results, we calculated environmental risk of air pollutants emitted in Iwate Prefecture. As a result, it was found that the surround of factories with high emissions and highly toxic chemicals and the roadsides were high risk area, benzo(a)pyrene, formaldehyde and ozone exceeded the $10^{-5}$ risk level. Moreover, we tried to use "Loss of life expectancy: LLE" for an index to explain those risk to general public intelligibly. The total LLE of the carcinogenic chemicals was about 8.6 hours. Moreover, LLE of ozone was about 9.2 hours. Ozone has a big influence compared with the carcinogenic chemicals.

Masonry arch bridges present a large segment of Iranian railway bridge stock. The ever increasing trend in traffic requires constant health monitoring of such structures to determine their load carrying capacity and life expectancy. In this respect, the performance of one of the oldest masonry arch bridges of Iranian railway network is assessed through field tests. Having a total of 11 sensors mounted on the bridge, dynamic tests are carried out on the bridge to study the response of bridge to test train, which is consist of two 6-axle locomotives and two 4-axle freight wagons. Finite element model of the bridge is developed and calibrated by comparing experimental and analytical mid-span deflection, and verified by comparing experimental and analytical natural frequencies. Analytical model is then used to assess the possibility of increasing the allowable axle load of the bridge to 25 tons. Fatigue life expectancy of the bridge is also assessed in permissible limit state. Results of F.E. model suggest an adequacy factor of 3.57 for an axle load of 25 tons. Remaining fatigue life of Veresk is also calculated and shown that a 0.2% decrease will be experienced, if the axle load is increased from 20 tons to 25 tons.

Noncommunicable diseases (NCDs) are the most important causes of premature mortality and disability-adjusted life years in Korea. NCDs are also the main contributor to socioeconomic inequalities in mortality and life expectancy. Reduction of NCDs and NCD inequalities would result in significant improvement in healthy life expectancy and health equity in Korea. Major NCD risk factors such as dietary risks (including salt intake), alcohol consumption, cigarette smoking, and high blood pressure were found to be the leading modifiable risk factors of disability-adjusted life years in Korea, based on the 2010 Global Burden of Disease Study. Several Korean studies have shown that these risk factors play an important role in creating socioeconomic inequalities in NCD mortality and total mortality. Current international discussions on NCD policies in the United Nations and the World Health Organization would provide better opportunities for developing aggressive population-wide policy measures in Korea. Considering the paucity of population-wide policies to control major NCD risk factors in Korea, rigorous population approaches such as taxation and regulation of unhealthy commodities as well as public education and mass campaigns should be further developed in Korea.
