Recreation forests are in the spotlight as the place for personality development, mind and body comfort, companionship, and environment education in forests and valleys. Visitors to recreation forests have been on the increase along with booming in recreation forest building since 1988. Recreation forests are being categorized according to some features such as regional and environmental condition. Recreation forests, however, have not met the expectations of some visitors who want to take a rest with calmness due to the influence of the 5-day-work-week system, increasing interest in rest, leisure, and well-being, and users converge during weekends, summer, and the tourist season. In order to improve visitors' satisfaction efficiently, this study surveyed the level of satisfaction in each cluster based on the precedent study which had classified 85 national or public recreation forests in Korea into clusters. Questionnaires were distributed properly to each cluster and, of the 1,132 questionnaires collected, 1,015 were valid and used for analysis. Reliability of questionnaires and statistical validity of the model were verified. As a result, there are meaningful differences in the ranking of independent variables which affect the level of satisfaction according to clusters. Variables in rest and fatigue recovery have the strongest influence on the level of satisfaction in the clusters of potential factor, internal activation factor, and mixed potential capacity factor. In the use performance and visiting condition factor cluster, appropriateness of visit cost is most influential and, in the education cluster, connectivity with tourist attractions around it is most affective. These results can provide priority in services and maintenance of recreation forests for improving the level of satisfaction and differentiate the distribution of resources according to clusters.

The purpose of this study was to prevent excessive use of fluorine toothpaste. To comparatively evaluate the amount used of the fluorine toothpaste in children from 3 to 6 years old, the toothpaste amount was compared according to toothbrush size and toothpaste squeezing method targeting 84 children in 5 child care centers where were located in Hongseong-gun, Chungnam. The toothpaste amount was compared with a method of squeezing to pea-size and a method of smear on toothbrush, targeting 141 students for the Dept. of Dental Hygiene, who are actually carrying out oral health education to targeting children. The statistical analysis was used SPSS 14.0 K for Windows program(Copyright(c) SPSS Inc.). The following results were obtained. 1. The amount of fluorine toothpaste squeezed on toothbrush for children was 0.29 g. The amount of fluorine toothpaste squeezed on toothbrush for adults was 0.34 g. It was surveyed to use the less amount of toothpaste when squeezing to smaller toothbrush (p<0.05). 2. The amount that children aged 3-6 squeezed as the method of squeezing commonly at ordinary times was 0.31g. The amount that was squeezing to pea-size was 0.21 g. The amount that was squeezed by using smear method was measured to be 0.26g. Less amount of fluorine toothpaste was used with the method of squeezing to pea-size and smear method rather than a method of squeezing commonly at ordinary times(p<0.05). 3. As a result of surveying the students of the department of dental hygiene, the amount of having squeezed to pea- size was 0.23 g. It was surveyed to be 0.15 g when having used the smear method. Thus, it was surveyed to use the less amount of toothpaste when using the smear method(p<0.05). 4. Using smaller toothbrush, the amount used of fluorine toothpaste can be reduced. Both smear method and the method of squeezing to pea-size are available for minimizing careless fluorine intake by less used amount of fluorine toothpaste.

The aim of this study was to investigate the oral health problems among type 2 diabetes patients and suggest basic data for the promotion of their body and oral health by emphasizing the correlation between hemoglobin A1c and subjective oral health status. For 174 patients with type 2 diabetes and who were older than 40 years old, the questionnaire and measurement of hemoglobin A1c were conducted from January 9, 2012 to March 9, 2012. The results of the study were as follows. 1. They tended to be most aware of the following; 'inflammation on the oral mucosa' and 'pain on the oral mucosa' among the symptoms of oral mucosa, 'gum bleeding when brushing teeth' among the symptoms of periodontal disease, and 'feels dry in general' among the symptoms of xerostomia. 2. The patients with longer duration of diabetes showed greater recognition with regards to the symptoms of oral mucosa disease, periodontal disease, and xerostomia (p<0.05). 3. The group with regular meal showed lower level of hemoglobin A1c (p<0.001). 4. The level of hemoglobin A1c was higher in the group that recognized 'burning sensation', 'gum bleeding', 'gum recession' and 'bad breath' (p<0.05) as well as in the group that responded 'get up at night to drink' among the symptoms of xerostomia (p<0.05). Especially the symptoms of periodontal disease were revealed to be a factor that showed the 3rd strongest correlation with hemoglobin A1c.

The purpose of this study was to examine the views of dental hygiene students about the possible countermeasure of domestic hospitals for the opening of the medical market. The subjects in this study were 269 dental hygiene sophomores, juniors and seniors at two different colleges in the region of Busan. The findings of the study were as follows: The opening of the medical market and views of possible countermove, whether they agreed to that or not made a statistically significant difference to their opinions on the necessity of customer-oriented marketing strategy(p=0.023), analysis of foreign medical markets/attempt to make inroads into the markets(p<0.000) and the improvement of the quality of medical services/the diversification of the services(p=0.025). As to an intention of going to a foreign hospital, they had a statistically significantly different intention about whether to go to a foreign hospital regardless of medical bills(p<0.000), whether to consult a doctor in a foreign hospital after going to a domestic hospital first (p<0.000), whether to consider the distance between their houses and a foreign hospital(p=0.05) and whether to take considerations on the assistance of an interpreter(p=0.023). In regard to preference for foreign hospitals, American hospitals ranked first(41.9), followed by Australian hospitals(19.9) and Canadian ones(14.2).

This study was conducted to investigate the role of drinking pattern in the relationship of alcohol consumption by face-to-face interview in rural elderly(n=994) aged 60~64 in Dalsung County, April to September in 1996. Pattern of alcohol drinking included drinking status, alcohol drinking at the morning without breakfast, average drinks per day, frequency of drinks per month, quantity of alcohol drinking, kind of preferred alcoholic beverage and duration of alcohol drinking. Blood pressure was measured once in each subject using a portable automatic sphygmomanometer. Difference in means of systolic blood pressure, alcohol drinking status, alcohol drinking at the morning without breakfast, and kind of alcoholic beverage were statistically significant before adjusting covariates, but alcohol drinking status and alcohol drinking at the morning without breakfast were statistically significant after adjusting covariates. And difference in means of diastolic blood pressure, kinds of alcoholic beverage was statistically significant before adjusting covariates, but no variables was significant after adjusting covariates. Model I multiple regression for systolic blood pressure that included average drinks per day as the variable of drink pattern, age, educational attainment and, previous history of cardiovascular disease were statistically significant, and multiple regression for diastolic blood pressure, educational attainment, BMI, and previous history of cardiovascular disease were statistically significant. Model II multiple regression for systolic blood pressure that included drinking patterns variables except average drinks per day, previous history of cardiovascular disease were statistically significant. However, multiple regression for diastolic blood pressure, no variables were significant. So, inconsistent with prior research, a positive relationship was not found between average drinks per day and diastolic and systolic blood pressure. The effect of alcohol drinking patterns on blood pressure has public health as well as clinical relevance. The study should be replicated to determine the reliability of our findings.

Objectives: Colorectal cancer is one of the major cancers in South Korea. We described the time trends in colorectal cancer incidence in Daejeon, a metropolitan city, and Chungcheongnam-do (Chungnam), a rural province, South Korea. Methods: Using the databases from the Daejeon Cancer Registry (DCR) and the Chungnam Cancer Registry (CCR), age-standardized (to world standard population) rates for incidence (ASRW) were calculated. Average annual percent change (AAPC) was assessed as a trend indicator. The completeness (such as the mortality/incidence ratio) and validity (such as the death certificate only %, microscopic verification %, primary site uncertain %, and age unknown %) were analyzed to examine the data quality of DCR and CCR. Results: Incidence of colorectal cancer showed increasing trend in both sexes. Over the years 2000-2012 in Daejeon, ASRW was increased significantly from 37.2 to 51.7 per 100,000 person-years (AAPC, 3.9%) among men and from 17.1 to 28.4 (AAPC, 3.9%) among women, respectively. In Chungnam, ASRW was also increased from 29.8 to 50.1 per 100,000 person-years (AAPC, 5.1%) among men and from 15.9 to 26.6 (AAPC, 3.2%) among women, respectively. The AAPC for colon cancer was greater than rectal cancer in both Daejeon and Chungnam. The trend of rectal cancer incidence was differ by sex (AAPC in men vs women, 2.7% vs 1.7% in Daejeon; 3.5% vs 0.8% in Chungnam). Indices of completeness and validity showed that the quality control of DCR and CCR was adequate to describe the trends of ASRW. Conclusions: Both Daejeon and Chungnam have had a rapid increase in colorectal cancer incidence. Monitoring and intervention are required on the risk factors which may contribute to this trend.

Objective: A prediabetes hemoglobin A1c (HbA1c) level of 5.7%-6.4% is considered a risk factor for diabetes mellitus and cardiovascular disease (CVD) in the USA. In this study, we assessed the HbA1c and visceral fat levels as CVD risk factors in health check-up examinees who were not yet diagnosed with diabetes. Methods: Totally, 507 study subject were categorized as per criteria of the American Diabetes Association, depending on whether the HbA1c level was ${\geq}5.7%$ or <5.7%. Lipid levels, blood pressure, BMI (kg/$m^2$), total abdominal, and visceral fat levels were measured by computed tomography. Results: The mean of HbA1c in the male group was larger than the mean in the female group and their values were, respectively, $6.03{\pm}0.82%$ and $5.88{\pm}0.72%$(p<0.05). Only the mean values of age and visceral fat area were different between $HbA1c{\geq}5.7%$ and <5.7% in both male and female group(p<0.05). Visceral fat levels were significantly associated with HbA1c in the group of HbA1c ${\geq}5.7%$ (odds ratio=1.005, 95% CI 1.002~1.008). Conclusions: Visceral fat levels were significantly higher and correlated with the group which HbA1c level is ${\geq}5.7%$. This finding suggests that subjects who have high levels of HbA1c should be carefully monitored during prediabetes and should have chance to have health education programs.

Objectives: Pregnant women in rural areas do not have access to sufficient obstetric services in their own communities due to the shortage of obstetricians. Therefore, most of these women must seek obstetrician outside of their communities. The purpose of this study was to investigate the relationship between obstetric complications and accessibility to local obstetric care in Korea. Methods: This study was an ecological study in which the unit of analysis was an administrative district. Using Korea National Health Insurance Corporation data, the total number of deliveries and the delivery proportion within and outside of the community from 2001 to 2008 were calculated for 232 administrative districts nationwide. Three outflow levels were categorized based on each district's out-of-community delivery proportion: high outflow (upper one third), moderate outflow (middle one third), and low outflow (lower one third). In addition, three obstetric complication rates (the rate of complications following abortion, ectopic and molar pregnancy, the abortion rate, and the eclampsia rate) were calculated for the 232 districts. One-way ANOVA and multivariate linear regression were used to evaluate obstetric complications among the three outflow levels. Results: The high outflow districts had higher rates of eclampsia and complications following abortion, ectopic, and molar pregnancy compared to the other districts (ANOVA, p<0.05). However, there was no significant difference in the abortion rate among the three groups. Multiple linear regression analysis showed that high outflow districts were statistically significant in the rate of complications following abortion, ectopic and molar pregnancy and eclampsia rate after adjusting for local tax per capita (p<0.01). Conclusion: These results indicate that poor access to local obstetric care correlate with poor obstetric outcomes (delayed or excessive bleeding, embolism, genital tract or pelvic infection, shock or other complications following abortion and ectopic or molar pregnancy, or eclampsia).

The grafting of a kidney has been found to be the best medical treatment for patients who have renal insufficiency failure, but the patients still have experienced much trouble and apprehension. This study was done to further nursing theory developing for patients who have has a kidney graft from another person. The research method followed grounded theory methodology of Strauss and Corbin. The subjects were three female and four male patients. This study done befween Oct. 1997 and Mar. 1998. All of the subjects were interviewed by the author. Interview were done by the long interview technique and observation. In the process of data analysis, 'heart-boiling' was found to be the core phenomenon. The results were composed to 101 concepts. These concepts were grouped into nineteen categories, and then to twelve categories. There were 12 super-class categories as follows ; 'pain', 'heart-boiling', 'experience of dialysis', 'term of admission to a hospital', 'support of other person', 'dependence on God', 'direction', 'negative reaction', 'positive reaction', 'comfortable', 'lacking', 'acceptance'. In this process, 14 hypotheses were derived from the categories as follows ; (1) The more experience with dialysis that the patients have, the stronger the heart-boiling will tend to be. (2) The less experience with dialysis the patients have, the weaker the heart-boiling will tend to be. (3) The longer admission to hospital the patients have, the stronger the heart-boiling will be. (4) The shorter the admission to hospital the patients have, the weaker the heart-boiling will be. (5) The weaker the intense-grief is, the more positive the reaction to heart-boiling the patients wll have. (6) The stronger the intense-grief is, the more negative the reaction to heart-boiling the patients will have. (7) The stronger the support of other persons that the patients have, the more positive the reaction to heart-boiling the patients will have. (8) The weaker the support of other person that the patients have, the more negative the reaction to heart-boiling the patients will have. (9) The stronger the dependence on God that the patients have, the mure positive reaction to heart-boiling the patients will have. (10) The weaker the dependence on God that the patients have, the more negative reaction to heart-boiling the patients will have. (11) The more positive thoughts that the patients have, the more positive reaction to heart-boiling the patinets will have. (12) The more negative thoughts that the patients have, the more negative reaction to heart-boiling the patients will have. (13) The more positive reaction the patients have, the more free from heart-boiling the patients tend to be. (14) The more negative reaction the patients have, the less free from heart-boiling the patients tend to be. From the analysis of observed data and comparing each class, I concluded that there are four formula relation types between reaction of patients and heart-boiling. (1) If patients have the experience of dialysis, have a long term admission to hospital, are strong in heart-boiling, depend on God, have positive thoughts and another's strong support, they experience release by positive reaction to the intense-grief. (2) If patients have the experience of dialysis, have a short term admission to hospital, are weak in heart-boiling, do not depend on God, have negative thoughts, and have few supports from others, they experience attachment to heart-boiling though a negative reaction. (3) If patients have the experience of dialysis, have a long term admission to hospital, are strong in heart-boiling, do not depend on God, and have negative thoughts, they experience attachment to heart-boiling through negative reaction in spite of support from another. (4) If patients have the experience of dialysis, have a long term admission into hospital, are strong in heart-boiling and satisfaction is low, but they have positive thoughts, then they experience acceptance and harmony through the positive reaction to heart-boiling. The results of this study are expected to help the way nurses care for patients who have had a kidney graft from another.

Background : The purpose of this study was to analyze the smoking habits in patients with lung cancer and identify any difference of prevalence according to histologic types of lung cancer. Methods : The data were calculated by total amounts of tar and nicotine inhaled during the whole lifetime according to variation of smoking habit. This study was to investigated any difference of prevalence in lung cancer according to smoking habits. The subjects comprised 150 lung cancer cases and 300 hospital control cases that were matched by age and sex. Smoking habits during the whole lifetime were surveyed by standardized questionnaire. Odds ratios were estimated by unconditional logistic regression analysis. Results : There were 104 male and 34 female lung cancer cases. By histologic type, there were 53 cases of squamous cell carcinoma, 67 of adenocarcinoma and 30 of small cell lung carcinoma. The differences between lung cancer cases and controls according to smoking habits were total duration of smoking, total pack years of smoking and number of cigarettes smoked per day during the previous two years. The odds ratio were higher in Kreyberg I, but not in Kreyberg II, for the longer duration of smoking, the greater total pack years of cigarettes consumed, the more cigarettes smoked per day during the previous two years, the longer duration on non-filter smoking, the earlier life cases who began to smoke, and the higher amounts of calculated total tar and nicotine inhaled over the whole lifetime. When we added grade of inhalation to calculation of amounts of tar and nicotine inhaled over the lifetime, the odds ratios of total inhalation amounts of tar and nicotine were as high as those the without them. Conclusions : This study reconfirmed that smoking habits were strongly associated with lung cancer and that there were different associations between smoking habits and histologic types of lung cancer. In particular, calculations of total tar and nicotine amounts inhaled over the whole lifetime were calculated for the first time in trials from lung cancer epidemiologic studies.
