The aim of this study is to clarify what influence has on elementary school children's environmental awareness in time of teaching environmental problems from an animistic viewpoint and from non-animistic viewpoint. For this purpose, this study carried out its research targeting 126 students in fourth grade at M elementary school located in U Metropolitan City. This study suggested the environmental problems by re-edifying the already suggested environmental problems from an animistic viewpoint to 62 students for two classes which were classified as an experimental group after sampling 10 cases of the representative environmental problems that might derive from the earth system, and conducted the class on 10 main topics relevant to the problematic situation of environment with an animistic viewpoint excluded targeting the remaining 64 students forming a comparison group. The results of this study were as follows: First, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. This study interprets this result to mean that elementary students' awareness of environmental problems increase because they think about the environmental problems by associating them with a problem of life when the students receive the environmental class from an animistic viewpoint. Second, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. Regarding this aspect, this study believes that the experimental group shows much higher willingness to environmental act in comparison with the comparison group because elementary school students think of inanimate objects as living things.

Objectives: This paper aimed to contribute to better oral disease prevention and practice of health behavior for immigrant women in multi-cultural families, to define missing and filled permanent teeth index of immigrant women, data from the 6th Korea National Health and Nutrition Examination Survey from the Korea Centers for Disease Control and Prevention was used. Methods: For the immigrant women to be subjects, they needed to be born overseas, had acquired Korean citizenship as a married immigrant women, and the estimate of the number of subjects was 133,093 women. For analyzing data, SPSS 21statistical program was used. We used covariance analysis (ANCOVA) andgeneral linear models for finding the relation with the missing and filled permanent teeth index. The significance level was 0.05. Results: DMFT-index of immigrant women was 7.33 points. $R^2$ was 0.416; and increased with age, and $R^2$ was 0.126 points higher (p<0.01). In household income, 'lower' was 5.933 points lower than 'upper' (p<0.05), and in toothbrushing after lunch, 'yes' was 3.598 points lower than 'no' (p<0.01). In preventive treatment, 'yes' was 4.301 points lower than 'no' (p<0.05). Conclusions: The result of this paper is as follows: for maintaining oral health of immigrant women, we think that the government needs to develop an oral health policy and a customized education system suited to immigrant women for preventive management of dental disease in immigrant women. In addition, basic data will be provided for public dental health programs based on the result of the study.

Despite its universal coverage of health insurance, the rural health insurance program(RHIP) stands at the crossroads in Korea. The RHIP has weaknesses in stability of financing, problems of inequities in the provision of health services and has suffered from high cost of running the program. The author has analyzed these problems from the perspective of health insurance policy and presented several options for improvement. First of all, this study urged the importance of a firm Governmental commitment of RHIP with the 50% subsidization of contributions as the Government had promised, instead of the current 40%. This can be justified from the 20% subsidization by the Government for the contributions of private school teachers and their dependents, who belong to richer segments of the population. Second, various cost containment measures ought to be sought curbing the rising demand for medical through strengthening health education and increasing individual responsibility, and tightening the claim review process. Third, this study requires the Government to run a demonstration project on the introduction of case payment system for primary health care. Fourth introducing an income-related cost sharing scheme is another possibility. Reforming the cost sharing formula for large medical expenditures is recommendable for a beginning. This measure can take the form of tax credit for medical expenditures of the poor. Fifth, the degree of financial adjustment among health insurance plans should be levelled up for enhancing stability of RHIP and social solidarity. Sixth, health policy should be redirected toward development of rural health resources and higher priority should be put on relieving difficulties in access to care. Seventh. the insurance plan owned-hospital needs to be developed or provision of health services in the medically underserved areas, and the need of such facilities is particularly acute for geriatric care, rehabilitation and renal dialysis, etc. Eighth, more generous insurance benefits are required of the elderly who are suffering the most : elimination of the maximum 180 days of benefit period and provision of glasses and artificial dentures, etc. Ninth. the economies of scale principle is working for the operating expenses of regional self-employed insurance plan. Thus, measures should be instituted to pursue an optimum size of health insurance plans. Lastly, excessive dependence on exclusion items is an evil so that some radical remedies are urgently required to cut them.

Objective: gastric cancer is the fourth most common cancer worldwide. While it is one of the most common cancers in Iran, there are only limited data regarding incidence trends in the country. This study is the first of its type to investigate trends across six geographical areas during 2000-2005 using cancer registry data. Materials and methods: The registered data for gastric cancer cases in National Cancer Registry System were extracted from the Ministry of Health and Medical Education, Center for Disease Control & Management, code C16. First, according to WHO population, the sex-standardized incidence rate in both sexes and then the trends of incidence rate during 2000-2005 were investigated separately for different geographical areas of the country. Results: the incidence rates of gastric cancer in Iran and its six geographical areas during 2000-2005 were increasing albeit with differences in their slopes. The overall incidence rate increased from 2.8 in 2000 to 9.1 per 100,000 persons per year in 2005, rising from 4.1 to 13.2 in men. The average six-year incidence of gastric cancer in the central and northwestern border of Caspian Sea was 7.8 per 100,000 persons per year, while it was 0.9 per 100,000 persons per year in the border of the Persian Gulf. Generally the incidence rate in men was higher than in women. Conclusion: Iran is one of the high-risk areas for gastric cancer. Increase in incidence might continue in the future partly because of improvement in cancer registry systems as well as increase in risk of this cancer.

There has been 10 years since The Health Promotion Act was legislated. The government began to establish a health promotion fund on the basis of Health Promotion Act in 1995, and to manage and operate the fund from 1998. It is evaluated that health promotion program have had various outcomes in many aspects. First, there has been growing awareness of the impotance of health promotion through the establishment of Health Plan 2010 and the effort to actualize the Plan. Second, the importance of securing health equity and identifying health determinants have been recognized during the planning process of Health Plan 2010. Third, the health promotion program have mainly focused on improving healthy life style of the population. As a result, desirable health behavior change of the population could be expected from the result of 2005 National Health and Nutrition Survey. Fourth, public health centers began to play a crucial role in implementing health promotion programs, and began to build infrastructure for health promotion programs. Fifth, the outcomes of health promotion programs by public health centers and private health organizations have been increasing. Finally, training for health promotion personnel and their participation in the program could be the foundation for the higher level of outcome achievement from the health promotion programs. Important challenges for future health promotion would be identification of the determinants and risk factors of health in Korea, establishment of local health promotion plan, building infrastructure for health promotion, creation of specific action model by public health center, development of diverse health promotion programs and health promotion program for the elderly, conducting research for evidence concerning major factors reducing the need for health care through prevention disease activities, and establishment of evaluation and feed back system for health promotion programs.

Smartphone addiction has become more serious than internet addiction since people can download and run numerous applications with smartphones even without internet connection. However, smartphone addiction is not sufficiently dealt with in current studies. The S-scale method developed by Korea National Information Society Agency involves so many questions that respondents are likely to avoid the diagnosis itself. Moreover, since S-scale is determined by the total score of responded items without taking into account of demographic variables, it is difficult to get an accurate result. Therefore, in this paper, we have extracted important factors from all data, which affect smartphone addiction, including demographic variables. Then we classified the selected items with a neural network. The result of a comparative analysis with backpropagation learning algorithm and multiclass support vector machine shows that learning rate is slightly higher in multiclass SVM. Since multiclass SVM suggested in this paper is highly adaptable to rapid changes of data, we expect that it will lead to a more accurate self-diagnosis of smartphone addiction.

Objective: The purpose of this study was to evaluate the patterns of Over-the-Counter (OTC) drugs and their interactions with prescription drugs in adults visiting a community pharmacy. Method: The subjects were 151 adults aged over 20 years visiting a community pharmacy in Asan-si from December 16th 2011 to February 1st 2012. We used a survey questionnaire. The survey inquired about the prevalence and the details of any OTC drug use and the characteristics of the study subjects. The drug interaction classification system from Lexicomp's Lexi-interact data fields was used to identify OTC drugs likely to have clinically significant interactions with prescription drugs. Results: The patterns of OTC drug use were related to thirties (from 30 to 40 years old), female gender, higher education, non-smoking, sometimes use of alcohol, and self-perceived normal health status. The most commonly used OTC drug category was antipyretic-analgesics (n=104, 53.3%), and the most commonly used ingredient was acetaminophen (n=67, 64.4%). The biggest motivation for taking OTC drugs was suggestion by pharmacists, reported by 55.6%. After reviewing each patient's prescription drugs and OTC drugs, 14 patients (36.8%) of 38 patients using prescription drugs were taking drug combinations with potential for clinically significant interactions. The concomitant use of OTC drugs with prescription drugs may lead to increased potentially harmful interactions. Conclusion: It is suggested that health-care professionals should be more aware of the potential and possible interactions and take into better account their patients' OTC drug use.

This study examines the determinants of emergency care utilization and equity of access to care in elderly Koreans. Based on the data from the 2014 Korea Health Panel Survey, descriptive and logistic regression analysis was performed. The sample for this study was 1,313 individuals who participated in interviews. Predisposing factors such as age, sex, and education were significant determinants of emergency care utilization. Differences in need do not fully account for the original differences observed between subgroups of older Koreans. Health status was important determinant of older Koreans using emergency care services. Spending medical expense did not ameliorate the subgroup differences in the use of emergency care services. Nonetheless, spending medical expense remains a particularly important predictor of emergency care utilization. Health care reforms in Korea should continue to concentrate on insuring effective universal emergency care, implying that all older Koreans with need receive effective coverage. Future study is also needed to understand the access barriers that may exist for the selected demographic subgroups, i.e., those over 75, women, less educated persons, and those with higher medical expense.

This study is to describe morphological linear anomalies manifested in the geomorphological landscapes of Woongcheon river-basin, situated in the western ends of Charyong Mountainous Range, and to elucidate their morphotectonic significance. The order of decreasing valley scale in the study area is NE-SW, NNE-SSW, NNW-SSE, N-S, and E-W series. The valleys of NE-SW lineament appear as the largest in the study area, having piedmont slope, terraces, low-relif hills. NNE-SSW lineament cross obliquely the geomorphological elements of the precedent lineament. NNW-SSE, N-S and E-W lineament cut the forms of higher orders showing NE-SW and NNE-SSW lineament. Scale of the linear valleys is not correlated with the order of streams. It is paradoxal that great valleys are not associated with the rivers of highest order. It owes to adaption of regional discharge system along the valleys exploiting the fracture resulted from succeeding tectonic accidents.

One of the serious modern environmental problems is pollution caused by highly toxic pesticides. Only small amounts of applied pesticides reach their target, and the rest ends up in soil and water. Chlorpyrifos is a toxic, broad-spectrum organophosphate insecticide. In humans, chlorpyrifos inhibits acetylcholinesterase (AChE) in the peripheral and central nervous system, and particularly in children, small amounts of this pesticide cause neurotoxic damage. As the toxic effects of chlorpyrifos and its persistence in the environment require its removal from contaminated sites, it is essential to study the biological diversity of chlorpyrifos-degrading microorganisms. In this study, we sought to determine the chlorpyrifos-degrading ability of the bacterial strain Ochrobactrum intermedium PDB-3. This strain was isolated from soil contaminated with various pesticides and identified as PDB-3 based on morpho-cultural characteristics, MALDI-TOF MS, and 16S rRNA. Studies were conducted for 30 days in sterile soils containing initial concentrations of 50, 75, 100, and 125 mg/kg of chlorpyrifos. To determine the degradation of chlorpyrifos, a liquid culture of the strain was added to the soil at three optical densities: 0, and after 24 and 48 h (OD = 0.03, 0.2 and 0.32). Using GX-MS, we determined that chlorpyrifos was converted to 3,5,6-trichloro-2-pyridinol (TCP). We also found that with increasing optical density, rapid degradation of the initial concentration of chlorpyrifos occurred. Sterile soil without strain PDB-3 was used as a control sample.
