Objectives: The purpose of this study was to prevent health problems and environmental contamination resulting from inappropriate management of dental wastes and to provide reference data for revision and supplementation of dental clinic waste management guidelines. Methods: From 640 total of dental clinics registered in 16 cities and counties in Gyeongsangnam-do, 100 (60 in Changwon (Masan, Changwon), 29 in Gimhae, and 11 in Jinju) were included in this study. From July 2010 to September 2010, investigators visited the 100 dental clinics and conducted survey interviews using a structured survey questionnaire regarding disposal methods for liquid wastes (suction pump, spittoon container waste, used liquid disinfectants, and X-ray developer), and disposal methods for solid waste (suction pump, spittoon container waste, and general medical waste). Results: All the 100 dental clinics were found to treat liquid waste from suction pumps and spittoon containers in the same manner as general waste water. Nineteen percent of the clinics treated solid waste that was not filtered through the filter of a suction pump as general waste. Fifty or more percent of the clinics treated solid waste in spittoon containers as general waste. Seventy percent of the clinics used disinfectant solution, although most of them treated used disinfectants in the same manner as general waste water. Some clinics treated used X-ray developer and X-ray fixer in the same manner as general waste water. In most of the clinics, used drapes were washed within the clinic. Conclusions: It was found that waste water and dental wastes at some dental clinics were treated in inappropriately. Thus, in conclusion, the development of guidelines regarding proper management of liquid and solid dental waste at dental clinics is required, and hygiene and environmental training for workers at dental clinics is necessary.

This paper is focused on the sustainability of public rental housing policy. We have analyzed the general fiscal conditions of central government, the public welfare fiscal conditions, the public expenditure on rental housing, and the Korea Land & Housing Corporation (LH) financial structure. Central government fiscal conditions is controlled by the midium-term fiscal operation plan(2010~2014) and fiscal rules. And the fiscal mandatory expenditures on welfare is increased rapidly by the expansion of beneficiaries, but the fiscal discretionary expenditures particularly on public rental housing can be gradually cut down. LH, the dominant agency responsible for affordable housing, is now confronted with financial distress accruing to excessive burden for public rental housing construction. As a result this paper, we find the discrepancy between the fiscal conditons and public rental housing policies. We suggest the fiscally sustainable rental housing policy. Firstly, the construction plan should be realized reflecting the market and fiscal conditions. Secondly, the provsion and financing system of rental housing should be rebuild within the government fiscal condtions and financial ability of LH.

The purpose of the study is to provide basic data on the public health management in the industrial work places, and some implications on the public health education related to workers self care capacity of their own health. To achieve this purpose a questionnaire was provided to 332 workers during February 11-28, 1993. This was do in Changwon-shi Geojeoi-kun, Chungmoo-shi, Jinjoo-shi, of Kyeongnam province. Through the analysis of the survey results, a relationship was deduced between worker's general characteristics and basic elements of health management in the work place. The main results of this study can be summarized as follows : 1. In the knowledge area special health screening received the highest score 3.18. While the educational program scored the lowest .85. In the Attitude area the highest score was achieved in the affirmative attitude to the time consumed by health checks (3.28). The lowest by the management of health checks(1.53). In the Practice area, participation in health checking is the most active (3.44) , and public health education is the least active (0.95). 2. The differences of knowledge by workers' general characteristics is statistically significant in the work sector (P<.05), age (P<.05), sex (p<.001), marital status (P<.001), and prior career(P<.01). But in Attitude general characteristics are not significant factors. In the Practice area, did have a statistical significance, work sector (p<.001), age (p<.001), sex (P<.05), marital status (p<.001) and work career (P<.001). 3. The total difference by workers' general characteristics has a statistical significance only in the case of marital status (P>05). The note of married workers is higher than that of single workers. 4. The correlation between any two of Knowledge, Attitude, and Practice do have a statistical significance (p<.001).

Background: When cells are damaged by nicotine, cellular senescence due to oxidative stress accelerates. In addition, stress-induced inflammatory response and cellular senescence cause the accumulation of damaged organelles in cells, and autophagy appears to remove them. Conversely, when autophagy is reduced, harmful cell components accumulate, and aging is accelerated. This study aimed to determine the association between nicotine-induced cellular senescence and autophagy expression patterns in human gingival fibroblasts. Methods: Cells were treated with various concentrations of nicotine (0, 0.1, 0.5, 1, 2, and 5 mM) and 10 nM rapamycin was added to 1 mM nicotine to investigate the relationship between autophagy and cellular senescence. Cell viability was confirmed using WST-8 and the degree of cellular senescence was measured by SA-β-gal staining. The expression of the inflammatory proteins (COX-2 and iNOS) and autophagy markers (LC3-II, p62, and Beclin-1) was analyzed by western blotting. Results: The cell viability tended to decrease in a concentration-dependent manner. COX-2 showed no concentration-dependent expression and iNOS increased in the 0.5 mM nicotine treated group. The degree of cellular senescence was the highest in the 1 mM nicotine treatment group. In the group treated with rapamycin and nicotine, the conversion ratio of LC3-II to LC3-I was the highest, that of p62 was the lowest, and the level of Beclin-1 proteins was significantly increased. Furthermore, the degree of cellular senescence was reduced in the group in which rapamycin was added to nicotine compared to that in the group treated with nicotine alone. Conclusion: This study provides evidence that autophagy activated in an aging environment reduces cellular senescence to a certain some extent.

Purposes: The purpose of this study is to identify and analyze the factors that affect patients reusing non-face-to-face treatments at tertiary general hospitals. Methodology: We retrospectively analyzed a patient's reuse of non-face-to-face treatment from February 1, 2020, to December 31, 2021, at a tertiary general hospital in Seoul within one year of the first non-face-to-face treatment. A frequency analysis was conducted to identify the study subjects' demographic characteristics, treatment type characteristics, disease characteristics, and hospital use type characteristics. Also, across-analysis was conducted to verify the difference in non-face-to-face treatment reuse according to the characteristics a multiple logistic regression analysis was conducted to identify the factors affecting the reuse of non-face-to-face treatment by non-face-to-face treatment patients. Findings: The results of this study can be interpreted as indicating that the following groups are more likely tore use the non-face-to-face treatment: women, children, the elderly, Patients living far from the hospital, psychiatric patients, pediatric patients, medical benefits recipients, chronic patients, patients with mobility difficulties, and patients with high loyalty to hospitals. Practical Implications: When developing a non-face-to-face treatment system in the future, based on the results of this study, it is possible to target patients who prefer non-face-to-face treatment. And this study will be research material for vitalizing non-face-to-face treatment. In addition, the activation of the non-face-to-face treatment system will be an effective means for improving the quality of medical services and generating profits in hospitals in the future.

The level of cultural enjoyment in Korea has improved every year, but the culture that the general public possesses artworks has not developed so much. Most artwork trading systems, from traditional ones to the latest blockchain-based ones, are designed for expensive artwork trading and are hardly accessible to the general public. In this paper, we propose a blockchain-based artwork trading system that can improve the culture of the general public's art collection and contribute to the popularization of fine art. The proposed system consists of three interacted blockchains for identification, artwork registration and smart contract. The proposed system utilizes the advantages of the blockchain system for users to provide trust to each other, and introduces the concept of art notebook for artists to build trust in their own artwork. Since the proposed system builds a trust system through participants rather than experts or external organizations, it can reduce the cost of trading and deal with artworks that can be owned by the general public.

According to the results of the management evaluation of the nation's public firms over the past seven years, the rating of the port corporation is generally insufficient. According to the results of the seven-year study 2011-2017, the average debt ratio of the port corporation was 34.5%, two to three times lower than that of the general public company, the operating profit ratio of sales was three times higher, and the value added per person was 1.6-1.9 times better. However, the aggregate score and grade were generally low, with 4.1% of the total number of employees of the general public corporation, 10% of the average total assets, and 1% of the average sales volume. The distributed analysis results and panel return analysis results show that the size significantly impacts the overall score and grade. Additionally, major business standards such as port volume, not controlled by the port corporation, appear to have a decisive influence on the low grade of the port corporation. Thus, it appears that improvement and supplementation of key business indicators of port construction are urgently needed in the management evaluation system, which can be properly controlled.

The purpose of the study was to investigate the attitudes towards mathematics of high school students by comparing students of a general public school and a foreign language high school. The researchers were interested in how the two groups, middle or middle lower achievers and high achievers, showed their attitudes toward mathematics and where their attitudes were derived from. For the investigation, the researchers surveyed 121 students of general public high school and 64 students of a foreign language high school. Reliability, mean difference with t-test and frequency were analyzed. The results showed that many students from both groups had negative attitudes toward mathematics. However, the causes of the attitudes were different between the two groups. This implies that we need to reform the instructional methods and curricula of mathematics cources.

The drug trade among the general public via the Internet and sns have been increasing, which is becoming a social problem. The general public believe that even if they do the drug trade via the Internet and sns the probability of detection is low. so they will conduct drug trade via the Internet and sns. Therefore, if the general public recognize that there is a high likelihood of disclosure, drug trade via the Internet and sns are likely to decline. If the possibility of punishment increases through specification of controlled delivery techniques and Introduction of entrapment investigator, it seems that the general public can not easily deal with drug trade via the Internet and sns. Also by further subdividing the penalties for drug offenses, for simple drug buyers through cure-oriented treatment rather than punishment drug demand be suppressed and penalties for drug suppliers should be strengthened.

The Affordable Care Act (ACA) was signed into law on March 23, 2010 and will fundamentally alter health care in the United States for years to come. The US is currently one of the only industrialized countries without universal health insurance. The new law expands existing public insurance for the poor. It also provides financial credits to low income individuals and some small businesses to purchase health insurance. By government estimates, the law will bring insurance to 30 million people. The law also provides for a significant new investment in prevention and wellness. It appropriates an unprecedented $15 billion in a prevention and public health fund, to be disbursed over 10 years, as well as creates a national prevention council to oversee the government's prevention efforts. This paper discusses 3 major prevention provisions in the legislation: 1) the waiving of cost-sharing for clinical preventive services, 2) new funding for community preventive services, and 3) new funding for workplace wellness programs. The paper examines the scientific evidence behind these provisions as well as provides examples of some model programs. Taken together, these provisions represent a significant advancement for prevention in the US health care system, including a shift towards healthier environments. However, in this turbulent economic and political environment, there is a real threat that much of the law, including the prevention provisions, will not receive adequate funding.
