While sustainability is seen in terms of social, economic and environmental dimensions, securing longterm financial costs and planning long-term strategic perspective among policy-makers are needed to maintain a healthcare system sustainability. Thus, the networking and cooperation between policy makers and health care workers should be tightened and strengthened in order to keep and enhance the healthcare system sustainability.

This study looked into the current conditions in Korean and Japanese care management for the elderly, cases of consumer counseling in these countries, and the supporting institutions for Japanese users regarding the use of care management for the elderly. The number of recipients of care management for the elderly in both Korea and Japan is growing every year, and more Japanese users receive various services compared to Korean users. The results of an analysis on consumer counseling regarding the use of Korean and Japanese care management revealed, two types of complaints: counseling for the improvement of the institution and complaints related to the procurement of service. Regarding the insurance system, the complaints were mostly related to affirmation of a rating and the burden incurred by cost-sharing. Regarding the use of service, such key impairment cases were related to in-service medical accidents, illegal acts including caregiver contract violations and forced retirement, careless service by workers, and human rights violations of the elderly. Japan has developed governmental and, related-administrative and business services as well as a local governmental system to redress customer impairment issues as this pertains to service for better quality care management. In addition, they have enlarged the locally closed service, provided exact information about the services offered, and improved service appraisal techniques. The Japanese cases will serve as a good reference to improve the Korean system. In particular, the construction of a system that reduces customer losses and the availability of more counseling information are urgently required to improve the system in terms of customer experiences when they seek care management.

In this study, the existence of possible deterministic longterm trend of precipitation amount, monthly maximum precipitation, rain day, the number of rain day greater than 20mm, 30mm, and 80mm was analyzed using the Mann-Kendall rank test and the data from 62 stations between 1905 and 2004 in South Korea. Results indicate that the annual and monthly rainfall amount increases and the number of rain days which have more than 80mm rainfall a day, increases. However the number of rain days decreases. Also, monthly trend analysis of precipitation amount and monthly maximum precipitation increases in Jan., May, Jun., Jul., Aug., and Sep. and they decrease in Mar., Apr., Oct., Nov., and Dec. Monthly trend of the number of rain day greater than 20mm, 30mm, and 80mm increases in Jun., Jul., Aug., and Sep. However results of Mann-Kedall test demonstrated that the ratio of stations, which have meaningful longterm trend in the significance level of 90% and 95%, is very low. It means that the random variability of the analyzed precipitation related data is much greater than their linear increment.

The purposes of this study were to measure the solubility of the stannous fluoride experimentally, to find a method for improving the solubility of the stannous fluoride, and to observe the effect of longterm storage on the variation of the concentration of fluoride in the stannous fluoride solutions. By adding such materials as antiseptics, dye, flavor, and tastes to solution, the variation of the fluoride concentration was also observed. Ten groups of 0.4% stannous fluoride solutions to which glycerine, sodium chloride, chlorhexidine, dye, flavor, xylitol, and sorbitol were added were prepared. The measurements were carried out by direct calibration. The obtained results were as follows. 1. Effect of adding glycerine as solvent. : The solubility of stannous fluoride increased in the case of adding glycerine. By increasing the glycerine concentration, the fluoride level in stannous fluoride solution also increased. 2. Effect of adding sodium chloride and chlorhexidine. : Comparing to the case of pure water, low fluoride level was measured in case of adding sodium chloride and high fluoride level was measured in case of adding chlorhexidine. 3. Effect of adding erythrosin as dye and banna essence as flavor. : Adding erythrosin and banna essence didn't affect fluoride level. 4. Effect of adding xylitol and sorbitol. : The effects of xylitol and sorbitol were nearly the same as the effect of adding erythrosin and banna essence.

In this study, we investigated the effects of longterm exposure to ionic liquid (IL) on Shewanella oneidensis MR-1 (MR-1). MR1 was acclimated through repeated exposure to IL. The acclimated strain was named as S. oneidensis SH-1 (SH-1) and compared with MR-1 in various aspects including morphology, cell surface hydrophobicity (CSH), motility, and fatty acid. Compared to the MR-1, SH-1 showed elongated cell shape on scanning electron microscopy. Upon exposure to IL, hydrophobicity of SH-1 (28.2%) was higher that of MR-1 (3.3%). In contrast, motility of SH-1 (7 mm) was lower than that also of MR-1 (22 mm), and branched chain fatty acid of SH-1 was lower than that of MR-1, 27.6% and 41.1%, respectively.

Background: Bronchiectasis is characterized by chronic sputum production and complications such as hemoptysis and repeated infections. Even though some patients are cured by surgical resection of bronchiectatic lesions, most bronchiectasis patients can not be treated surgically because of multiple site involvement, and they are treated by medical measures such as postura1 drainage and antibiotics when indicated. Recently there have been some reports that low-dose longterm erythromycin treatment is effective on bronchiectsis, and it is well known that low-dose longterm erythromycin treatment is the treatment of choice in diffuse panbronchiolitis which is characterized by chronic sputum production and dyspnea. To evaluate the efficacy of erythromycin, we tried erythromycin on twenty five stable bronchiectasis patients for more than six months. Methods: We tried erythromycin 250 mg b.i.d. for more than 6 months. We checked respiratory symptoms, chest PA, spirometry, and side effects before treatment and after 3 and 6 months of treatment. Results: 1) 32% of the patients showed marked improvement of symptoms and PFT. 32% showed slight improvement of symptoms with little change of PFT, and 36% showed no change of symptoms and signs. 2) Analysis of the patients showing marked improvement revealed that most of them had diffuse bronchiectasis and paranasal sinus involvement. Conclusion: These results suggest that low-dose longterm erythromycin treatment can be tried on diffuse bronchiectasis patients with sinus involvement. And further studies will be followed on the mechanism of erythromycin in bronchiectasis.

This study compared parents' and teachers' feeding practices with young children. Parents and teachers of children aged 0-3 years were recruited at 24 child care centers to complete surveys regarding their demographic characteristics, parenting styles, and feeding practices with young children. Respondents included 106 parents and 102 teachers. Participants' feeding beliefs and values were found to be related to their parenting style classifications (i.e., Authoritative, Authoritarian, or Permissive), ethnicity, income, and other demographic characteristics. Findings indicate the need for teachers and parents to begin communicating about their longterm goals for a child's development as soon as the child enters care. Understanding the goals and variation of feeding practices used at home and at school can help teachers and parents begin to construct a shared vision for care.

The coverage of the National Health Insurance for the elderly is expanding to denture and implants. Although the National Long-Term Care Insurance was just being settled, Oral health service was not provided to the Elderly in Long-Term Care Facilities. The long-term care facilities had part-time facility doctors. However, there is no dentist in the long-term care facility because of lack of long-term care insurance-related legislations. The amendments of long-term care insurance-related legislations for the introduction of part-time facility dentists are needed because the elderly in long-term care facility are vulnerable to oral health. For the substantial management of the National Long-Term Care Insurance, the development of oral health service model for the elderly and education materials for the dental team will be needed. Also, adequate dental service fee of the National longterm care insurance will be needed.
