Purpose: The purpose of this study is to evaluate the costs and benefits of individual home visiting health care using secondary data and literature review. Methods: The total number of subjects was 1,008,837. A specific program was classified into disease management, care of infant, child and women, or elderly care. The costs and effects of a program were identified from a societal perspective, and the effects were converted into monetary terms or benefits. The total cost was calculated in the way that medical expenses, travel costs and productivity losses were offset by the decrease in benefits and thus only the program budget was included in the total cost. Results: The total program cost was 47.6 billion won per year and the total annual benefit was estimated at 435.6 billion won. The benefits of arthritis management were the biggest among disease management programs. The net benefit was 388.0 billion won per year and the benefit/cost ratio was 9.16. Conclusion: Home visiting health care was validated to be economically effective. It made a positive contribution to improving the health status of vulnerable populations and reducing medical expenses. These results suggest that home visiting care should be extended more broadly to vulnerable populations.

The monetary model suggests that nominal exchange rates between two countries will be determined by important macroeconomic variables. The existence of a cointegrating relationship among these fundamental variables is the backbone of the monetary model. In a recent paper, Rapach and Wohar (2002, Journal of International Economics) advance the literature by testing for linear cointegration in the monetary model using a century of data to increase power. They find evidence of cointegration in five or six of ten countries. We extend their work to the nonlinear framework by performing threshold cointegration tests that allow for asymmetric adjustments in two regimes. Asymmetric adjustments in exchange rates can occur, for example, if transactions costs are present or if policy makers react asymmetrically to changing fundamentals. Moreover, whereas Rapach and Wohar (2002) found it necessary to exclude the relative output variable in some cases to maintain the validity of their cointegration tests, we can include this variable as a stationary covariate to increase power. Overall, using their same long-span data, we find more support for cointegration in a nonlinear framework.

Objectives: Photodynamic therapy has been proven to promote additional clinical and microbiological benefits in the treatment of chronic periodontitis and aggressive periodontitis. The purpose of this study is to assess the effectiveness of the photodynamic therapy for patient with periodontitis. Methods: We searched the eight Korean databases and Ovid-MEDLINE, Ovid-EMBASE, Cochrane Library. Total 300 studies were searched and 13 studies were included in the final assessment. Each of the stages from literature search and extraction of data were carried out independently by 2 researchers. We used tools of Scottish Intercollegiate Guidelines Networks for assessment of the quality of studies. Results: The safety of the photodynamic therapy was assessed by bleeding. The effectiveness of the photodynamic therapy was assessed by the reduction of Probing pocket depth (PPD) and the gain of Clinical attachment level (CAL). The mean difference of PPD was 0.46(95% CI 0.09~0.82), (p=.01).). The mean difference of CAL was ?0.49(95% CI ?1.12~0.14), (p=.13). Conclusion: The additional use of $^{\circ}{\infty}$Antimicrobial Photodynamic Therapy for Periodontitis$^{\circ}{\pm}$ caused hemorrhage to similar extents to conventional treatment modalities, where scaling and root planing are solely performed, in patients with periodontitis who are expected to have a lower degree of treatment response to non-surgical or surgical periodontal therapies (implant or refractory periodontitis) and those where there is a concern for the possible occurrence of antimicrobial side effects or resistance. This indicates that there are no problems with its safety. But there were no consistent reports about the effects of the additional use of photodynamic therapy. This led to a decision that the safety and efficacy of the current technology deserve further studies (Recommendation rating of A, Classification of technology II-a).

This paper compares the monetary policy problem in open economies with that in closed economies. It is found that the monetary policy problems in open and closed economies are isomorphic even in the presence of distortions in a steady state and hence the optimal monetary policies have similar properties. On the other hand, the monetary policy maker in open economies has a distorted incentive to manipulate the terms-of-trade. Because of the additional distortion in open economies, there exist gains from international monetary policy cooperation even in the case of a unit intertemporal elasticity of substitution, in contrast to the literature that abstracts from distortions in a steady state. Also, it is found that in the presence of distortions inflation bias is decreasing in openness, which is line with empirical evidence. In addition, this paper presents a simple transformation so that methods in closed-economy models are easily applicable to open-economy models.

Objective: The Australian Pharmaceutical Benefits Scheme (PBS) is a national drug subsidy program. Given the similarity and comprehensiveness of the Australian PBS and the Korean National Health Insurance (NHI) data, these data are increasingly used for pharmacoepidemiological investigations, as well as international comparative studies. This study aims to introduce the various sources of publicly available PBS data and provide a practical guide to researchers conducting drug utilization studies. Methods: We searched literature and websites to detail and compare the collection, structure, components, and characteristics of each PBS data format. We identified different characteristics of the PBS data from the Korean NHI claims data which are mainly owing to their unique co-payment policies and data collection processes. In addition, the utilization and expenditure of atorvastatin, a widely used treatment for hyperlipidemia, were analyzed using two different sources of PBS data and the different results were interpreted. Results: There exist differences in when data were collected or non-subsidized uses of medicine were included among sources of PBS data. Additionally, two countries have different cost sharing methods inmedicine subsidy scheme; co-payment in Australia and co-insurance in Korea. Therefore, it should be noted that prescriptions under co-payment are not included in some data sources in Australia. Conclusion: Despite several analytical challenges, open access and easy data management are the strengths of the PBS data sources. A detailed knowledge of the PBS data can ensure robust methodology and interpretation of pharmacoepidemiological investigations or international comparative studies.

The trend of increasing consumption of less nutritious foods makes the college years a critical period to enlighten young adults regarding healthy living, nutrition knowledge, and physical activity. This current study aims (a) to examine the influence of confidence in nutrition knowledge on college students' health-related behavioral intentions, and (b) to investigate the moderating effect of gender on relationship between confidence in nutrition knowledge and college students' health-related behavioral intentions. The results provide empirical evidence of college students' health behaviors showing that confidence in nutrition knowledge leads to an increase in behavioral intention to eat healthy food and to involve in physical activities. Also, the greater influence of confidence in nutrition knowledge on behavioral intention to eat healthy food is found among females students than male students. This study contributes to university foodservice literature and operators by providing useful information.

Tooth wear is a multifactorial condition, leading to the loss of dental hard tissues. While for many years, tooth wear was a condition of little interest in daily clinical practice, nowadays this is changed. Tooth wear is becoming increasingly significant in maintaining the long-term health of the dentition. This becomes especially important when the dentition is kept relatively intact in the contemporary ageing population, and edentulism is decreasing. There is also evidence that the prevalence of tooth wear is growing. It is a natural consequence of the unidirectionality of tooth wear that it is frequently used as a means of individual age estimation. Tooth wear was very serious in ancient populations up to the medieval period. Tooth wear is thus studied in a wide variety of areas. The purpose of this paper is to summarize and analyze the many issues surrounding tooth wear through recent studies in various fields and to search for future research direction.

Purpose: The purpose of this study was to develop and validate a Nursing Competency Scale in Simulation (NCSS) for nursing students. Methods: A preliminary version of the NCSS of 14 items was derived from the literature. A panel of seven experts reviewed the preliminary version for content validation and developed 15 items scale. A convenient sample of 195 nursing students completed the survey and two evaluators measured the performances of nine teams in a simulation scenario with NCSS. The data were analyzed using exploratory factor analysis, descriptive statistics, independent t-test and Cronbach's alpha. Intraclass correlation coefficient (ICC) was used in order to estimate the degree of inter-rater reliability. Results: An exploratory factor analysis demonstrated that two factor structures of the NCSS explained 51.1% of the total variance. Two factors were named psychosocial skills and cognitive and psychomotor skills. The mean scores of NCSS between third and 4th grade were significantly different providing support for its known-group validity. Cronbach's alpha was .90 and ranged from .79 to .88. The overall ICC for inter-rater agreement was 0.89 (95% CI 0.03 to 0.98). Conclusion: This scale shows preliminary evidence for validity and reliability. It could be a useful instrument for measuring learning outcome in simulation for nursing students' clinical competency.

Cemento-osseous dysplasia occurs in the tooth bearing areas of the jaws and is probably the most common fibro-osseous manifestation. They are usually classified into three main groups according to their extent and radiographic appearance: periapical (surrounds the periapical region of teeth and are bilateral), focal (single lesion) and florid (scleroticsymmetrical masses) cemental-osseous dysplasias. Florid cemento-osseous dysplasia clearly appears to be a form of bone and cemental dysplasia that is limited to the jaws. Patients do not have laboratory or radiologic evidence of bone disease in other parts of the skeleton. For asymptomatic patients, the best management consists of regular recall examinations with prophylaxis and the reinforcement of good home hygiene care to control periodontal disease and prevent tooth loss. The treatment of symptomatic patients is more difficult. At this stage, there is an inflammatory component caused by the disease and the process is basically a chronic osteomyelitis involving dysplastic bone and cementum. Antibiotics might be suggested, but are not always effective. Two cases of florid cemento-osseous dysplasia diagnosed in two Korean females are reported with a review of the relevant literature.
