A lot of localization algorithms have been developed in order to achieve autonomous navigation. However, most of localization algorithms are restricted to certain conditions. In this paper, Monte Carlo localization scheme with a map-matching algorithm is suggested as a robust localization method for the Public Service Robot to accomplish its tasks autonomously. Monte Carlo localization can be applied to local, global and kidnapping localization problems. A range image based measure function and a geometric pattern matching measure function are applied for map matching algorithm. This map matching method can be applied to both polygonal environments and un-polygonal environments and achieves...

It is widely known that optimal control techniques are useful to measure the performance of macroeconomic policy. This paper examines how the method could be applies them to the evaluation of the public investment expenditures conducted by the local government of Choongbook Province in Korea. The numerical example illustrates the usefulness of the methods for the evaluation of the regional economic policies suggesting the main findings as follows: (1) If the local government of Choongbook Province had increased the public investment expenditures allowing the budget deficits for the first three to four years during the period between 1985 and 1990, its GRDP would have early risen to the ratio of more than three percent of Korea's total GDP. (2) The additonal welfare losses incurred by not following the optimal policy were 0.191 in 1986, 0.607 in 1987, 1.585 in 1988, and 0.132 in 1989, indicating that the public investment policy proves to be the best in 1989 and the worst in 1988.

This study focused on individual health education for people with hypertension who were being seen in public health centers. The program was an adjusted intervention program that considered the characteristics of each individual and reflected the individual's will to change. Each individual had a different lifestyle with different characteristics and habits so the study considered these individual's characteristics. A comparison was done of knowledge related to hypertension, self-efficacy, and self-care in these individuals. In order to determine the effectiveness of education given by the nurses the variables were measured before and after the individual health education program. The participants in this study were 85 people with hypertension who were seen at a public health center in G city. They were assigned to an experimental group (43) and a control group (42). A tool developed by Park Young-Im (1994) was used to measure knowledge related to hypertension and self-efficacy. A tool developed by Lee Young-Whee (1994) was used for self-care. Data collection was done for 10 weeks from March 24 to May 31, 2003 using interviews with questionnaires. The following is a summary of the results of the study. Hypothesis 1, 'the experimental group which had the individual health education will have higher knowledge scores on hypertension than the control group that did not have the individual health education' was supported (t=4.17, P=0.00). Hypothesis 2, 'the experimental group which had the individual health education will have higher self-efficacy scores than the control group that did not have the individual health education' was supported (t=4.06, P=0.00). Hypothesis 3, 'the experimental group which had the individual health education will have better self-care ability than the control group that did not have the individual health education' was supported (t=4.94, P=0.00). Based on the results of this study, the public health centers should develop an educational program that uses a variety of visual aids and assess the effects of the education on patients with different chronic diseases. After the development of an inclusive education program which will standardize health education effectively and provide a variety of teaching methods, study is needed to measure changes in lifestyle after education and to determine how much knowledge related to hypertension, self-efficacy, and self-care increase

Objectives: At the beginning of the coronavirus disease 2019 (COVID-19) pandemic, some countries imposed entry bans against Chinese visitors. We sought to identify the effects of border shutdowns on the spread of the COVID-19 outbreak. Methods: We used the synthetic control method to measure the effects of entry bans against Chinese visitors on the cumulative number of confirmed cases using World Health Organization situation reports as the data source. The synthetic control method constructs a synthetic country that did not shut down its borders, but is similar in all other aspects. Results: Six countries that shut down their borders were evaluated. For Australia, the effects of the policy began to appear 4 days after implementation, and the number of COVID-19 cases dropped by 94.4%. The border shutdown policy took around 13.2 days to show positive effects and lowered COVID-19 cases by 91.7% on average by the end of February. Conclusions: The border shutdowns in early February significantly reduced the spread of the virus. Our findings are informative for future planning of public health policies.

Background: The elevated risk of occupational infection such as tuberculosis among health workers in many countries raises the question of whether the quality of occupational health and safety (OHS) and infection prevention and control (IPC) can be improved by auditing. The objectives of this study were to measure (1) audited compliance of primary health-care facilities in South Africa with national standards for OHS and IPC, (2) change in compliance at reaudit three years after baseline, and (3) the inter-rater reliability of the audit. Methods: The study analyzed audits of 60 primary health-care facilities in the Western Cape Province of South Africa. Baseline external audits in the time period 2011-2012 were compared with follow-up internal audits in 2014-2015. Audits at 25 facilities that had both internal and external audits conducted in 2014/2015 were used to measure reliability. Results: At baseline, 25% of 60 facilities were "noncompliant" (audit score<50%), 48% "conditionally compliant" (score >50 < 80%), and only 27% "compliant" (score >80%). Overall, there was no significant improvement in compliance three years after baseline. Percentage agreement on specific items between internal and external audits ranged from 28% to 92% and kappa from -0.8 to 0.41 (poor to moderate). Conclusion: Low baseline compliance with OHS-IPC measures and lack of improvement over three years reflect the difficulties of quality improvement in these domains. Low inter-rater reliability of the audit instrument undermines the audit process. Evidence-based investment of effort is required if repeat auditing is to contribute to occupational risk reduction for health workers.

The purpose of this study is to estimate farmers' willingness to accept (WTA) of direct payment for increasing public benefit using the contingent valuation method. The double-bounded dichotomous choice and the open-ended question were used to measure WTAs for basic form and optional form, respectively. The results show that WTA for basic form was inversely proportional to the acreage. WTAs were KRW 1,694,001 with 2 ha or less, KRW 1,617,789 with over 2 ha~6 ha, and KRW 1,562,977 with over 6 ha. The results also indicate that WTAs for optional form are similar to payments of agricultural environmental conservation program except physical (chemical) control of pests and weed. The results of this study can provide useful information for the establishment of direct payment for increasing public benefit.

In recent years, prices have risen sharply, and housing has become an object of investment. Accordingly, the expansion of the supply of public rental housing with publicity and the conversion of pre-sale are emerging as an alternative to stabilize the housing market. However, the method of calculating the pre-sale price applied for each rental period has a problem that there is a large difference from the construction cost at the time of construction As an improvement measure, there is a method of applying a conversion price for 5-year public rental housing and the price control. Each has its strengths and weaknesses, and we apply the most appropriate improvement measures in consideration of present and future values.

The burden of cancer is growing globally and is one of the top leading causes of death. Information on cancer patterns are essential for effective planning of cancer control interventions. There is limited published information available on pattern of cancer for the state of Odisha, India. The present study was an attempt to explore the pattern and trend of cancer in Odisha. To fulfill the objectives retrospective data available from 2001-2011 at Acharya Harihar Regional Cancer Center (AHRCC), Cuttack, Odisha, were analyzed. Medical records of cancer patients were reviewed and relevant information on diagnosis, primary site and demographic data were retrieved. Data were entered and analyzed using SPSS 16.0 (SPSS Inc.). A total of 74,861 cancer inpatients were registered at AHRCC for the years 2001-2011. The proportion of females outnumbered males with female:male ratio 1.1:1. The number of female cases increased four folds and that of males three fold over the period studied. Malignancies such as oral cancer (16.93%), acute lymphocytic leukemia/non Hodgkins lymphoma (14.09%) and cancer of gastrointestinal tract (21.07%) are leading cancers among males and carcinomas of breast (28.94%), cervix (23.66%) and ovary (16.11%) were leading among females. Findings from this study indicate an overall increase in cancer reporting which could be regarded as proxy measure for overall cancer situation in Odisha. There is scope and need for integrating other government hospitals, existing private health service providers and research institutions across the state for better planning of cancer control program.

This paper empirically studies the effect of public procurement on small and medium-sized enterprises (SMEs) in the Republic of Korea using firm-level data. Public procurement, the purchase of goods and services from private firms by the public sector, is regarded as an important policy measure for providing support to firms, particularly SMEs. This study uses establishment-level panel data of the mining and manufacturing sectors from the Korean National Bureau of Statistics (Statistics Korea) and procurement history from the Korean Public Procurement Service to empirically estimate the effects of public procurement on firms' productivity (total factor productivity) and survivability. Using a propensity score matching estimation method, we find that participating firms showed higher productivity than non-participating ones in the control group only for the year of participation, that is, 2009. After two years, in 2011, they exhibited significantly lower productivity. In contrast, establishments that participated in public procurement for SMEs in 2009 were more likely to survive than those that did not do so in 2011. These results can be interpreted as the negative consequences of government intervention. The market's efficiency enhancement is hindered if underserving companies survive owing to government intervention but fail to improve efficiency.

Objectives: Tobacco control in Indonesia is very lenient compared to international standards. This study explored the perspectives of tobacco control stakeholders (TCSs) on the likelihood of advancing tobacco marketing regulation in Indonesia. Methods: Data were collected from TCSs who were members of the Indonesia Tobacco Control Network group in a modified Delphi study. We collected the data in 2 waves using a questionnaire that comprised a set of closed and open-ended questions. For this paper, we analysed 2 of the 3 sections of the questionnaire: (1) tobacco advertising, promotions, and sponsorship (TAPS) bans, and (2) marketing and retailing regulations. We conducted a descriptive analysis of the scores using Stata/IC.13 and summarised the comments for each item. Results: The TCSs viewed the measures/strategies across all aspects of TAPS and tobacco marketing regulation as highly desirable, but provided varied responses on their feasibility. They rated political feasibility lower than technical feasibility for most measures. Advancing TAPS measures and prohibition of selling to minors were considered more attainable by sub-national governments, while prohibition of tobacco corporate social responsibility was considered as the least feasible measure in the next 5 years. Conclusions: Despite little optimism for substantial national-level change, there is a positive expectation that sub-national governments will strengthen their tobacco control regulation. It is paramount that the government reduce tobacco industry leverage by implementing Article 5.3 of the World Health Organization Framework Convention on Tobacco Control. Extending advocacy networks beyond tobacco control groups and framing tobacco control more effectively are necessary steps.
