Objectives : This study was performed in order to investigate an immediate improvement effect of nasal obstruction after having patient with chronic rhinitis use nasal spray in nasal cavity after distilling Korean medicine, satisfaction for its fragrance and irritation and its effect continuance time. Methods : A questionnaire was performed for an immediate therapeutic effect of nasal spray 1, 2 and 3 weeks later after using spray by targeting 13 patients who used Korean medicine distillate spray for over 3 weeks among the patients who visited Sangji University Korean Medicine Hospital and whose symptoms were determined as chronic rhinitis and for whom Korean medicine distillate spray was prescribed. 3 weeks later after using spray, a questionnaire was performed for fragrance, irritation and continuance effect of Korean medicine. Immediate therapeutic effect being felt right after spraying was also surveyed and symptom scores was expressed from 10 to 0 and on the assumption that nasal obstruction symptom just before spraying was 10 points, symptom score after spraying was surveyed. In case of evaluation of satisfaction, satisfaction for fragrance and irritation of nasal spray was evaluated by scale based on full score of 5 point from 'very satisfied=5', 'satisfied=4', 'average=3', 'unsatisfactory=2' and 'very unsatisfactory=1', respectively. Effect continuance time after spraying was surveyed by dividing it into within 5 minutes, within 5-10 minutes, within 10-30 minutes and over 30 minutes. All the data was statistically analyzed by Friedman Test that is non-parametric test of Paired t-test and descriptive statistics. Results : Total surveyed patients were 13 persons including 6 males and 7 females and total average age was represented to be $27.1{\pm}17.7$ years old. Score of immediate nasal obstruction improvement effect at 1st week was $6.3{\pm}2.4$ points, at 2nd week $5.7{\pm}2.5$ points and at 3rd week $5.5{\pm}2.5$ points and when comparing 1st week, 2nd week and 3rd week statistically, p value was 0.047<0.05 and from this, it could be seen that the longer spray was used, the more was improvement effect represented with slight significance. In case of fragrance and irritation, both of its score was represented to be high as average $4.0{\pm}1.08 $points and average $4.4{\pm}0.8$ points, respectively. Effect continuance time below 10 minutes was represented in 8 persons who accounted for 61.5%. Conclusions: Immediate improvement effect of nasal obstruction being felt by the patients by using Korean medicine nasal spray could be confirmed and by having the patients use such spray for 3 weeks continuously, it could be realized that such effect was sustained and satisfaction for fragrance or irritation of Korean medicine nasal spray was significant. However, rather short sustained time was considered to be unsatisfactory and this shortcomings is required to be improved in the future.

Statistical control charts are useful tools to monitor and control the manufacturing processes and are widely used in most Korean industries. Many Korean companies, however, do not always obtain desired results from the traditional control charts by Shewhart such as the $\bar{X}$-chart, $\bar{X}$-chart, $\bar{X}$-chart, etc. This is partly because the quality charterstics of the process are not distributed normally but are skewed due to the intermittent production, small lot size, etc. In Shewhart $\bar{X}$-chart. which is the most widely used one in Kora, such skewed distributions make the plots to be inclined below or above the central line or outside the control limits although no assignable causes can be found. To overcome such shortcomings in nonnormally distributed processes, a distribution-free type of confidence interval can be used, which should be based on order statistics. This thesis is concerned with the design of control chart based on a sample median which is easy to use in practical situation and therefore properties for nonnormal distributions may be easily analyzed. Control limits and central lines are given for the more famous nonnormal distributions, such as Gamma, Beta, Lognormal, Weibull, Pareto, Truncated-normal distributions. Robustness of the proposed median control chart is compared with that of the $\bar{X}$-chart; the former tends to be superior to the latter as the probability distribution of the process becomes more skewed. The average run length to detect the assignable cause is also compared when the process has a Normal or a Gamma distribution for which the properties of X are easy to verify, the proposed chart is slightly worse than the $\bar{X}$-chart for the normally distributed product but much better for Gamma-distributed products. Average Run Lengths of the other distributions are also computed. To use the proposed control chart, the probability distribution of the process should be known or estimated. If it is not possible, the results of comparison of the robustness force us to use the proposed median control chart based oh a normal distribution. To estimate the distribution of the process, Sturge's formula is used to graph the histogram and the method of probability plotting, $\chi$$^2$-goodness of fit test and Kolmogorov-Smirnov test, are discussed with real case examples. A comparison of the proposed median chart and the $\bar{X}$ chart was also performed with these examples and the median chart turned out to be superior to the $\bar{X}$-chart.

This research was carried out to determine the performance rate of health related practices, to measure the agreement between morbidity by doctor's diagnosis and morbidity by subject' self-reported and the degree of association between health related practices and morbidity rate by doctor's diagnosis, to identify their effects on morbidity among rural area populations. The data were gathered by volunteer residents (over the age of 20) of Haman Myeon, Haman Gun, Kyeongsangnam Do in Korea, from June 10, 1993 to June 12, 1993 (369 male and 516 female). Face to face interview, lab, chest P-A, EKG and physical examination were completed. Descriptive statistics, agreement analysis and multiple logistic regression procedures were employed for analyses. The results of the study were summarized as follows : 1) Age adjusted morbidity rates by doctor's diagnosis and self-reported were 38.5% (male:37.3%, female:36.5%), 26.4% (male:33.3%, female:27.5%), respectively. Kappa coefficient between morbidity by doctor's diagnosis and morbidity by self-reported was 0.21 (male:0.21, female:0.22). 2) The frequency of disease by doctor's diagnosis was as follows: hypertension(15.3%), gastritis (9.6%), diabetes mellitus (8.5%), live. disease (8.1%), and degenerative arthritis (6.2%) in the study population. 3) Order of health practice performance rate was as follows: Males-normal body weight (62.1%), non-heavy alcohol consumption (57.5%), 7-8 hours of sleeping (50.1%), non-smoking (21.7%), and exercise (19.8%). Females- non-heavy alcohol consumption (97.3%), non-smoking (84.7%), normal body weight (57.8%), 7-8 hours of sleeping (45.0%), and exercise (9.9%). 4) There was no significant relationship between health related practice and morbidity except exercise among health related practices. 5) Health related practice index which was recategorized by high, medium, and low had effects on the probability of developing morbidity.

This study is designed to support the development and the teaching of revised curriculum of 2007 "Technology & Home Economics" by investigating the actual condition and the necessity of education for elderly housing education. Questionnaire survey was conducted with 488 high school students in Gyeongnam in 2008. The data analyzed by descriptive statistics, t-test, One-way ANOVA, Duncan's multiple range test by using SPSS 14 program. The results showed that most of the students were dissatisfied with their middle school education of elderly housing due to the lack of interesting and practical contents. Thus, various teaching-learning methods where student can experience and experiment is needed. Also, the students demanded more of factors of elderly housing, spacing plan, elderly welfare service and less of three-generation housing and senior housing in their elderly housing education. The needs of education contents differed among students depending on variables such as sex, graduated middle school, household income, dwelling space and length of residential years. Therefore, revised 2007 curriculum of "Technology & Home Economics" should include required contents in related chapters. Because there are significant differences among textbooks about elderly housing, further attention needs to be paid to the new textbooks in order to include education contents evenly. At the same time, teachers should organize their teaching contents considering the divergence of variables. The effect of elderly housing education will be maximized if the revised curriculum consists of more experimental activities such as elderly simulation in the local community.

This study has a purpose to provide information to help develop nursing intervention for demented elderly staying at home. For this purpose I analysed the relationship of patients' disturbing behaviors with their demographic and social characteristics, premorbid personality, and present environmental characteristics through questionnaire survey on their family members. The survey was performed through direct interview, telephone contact. and mail in the regions of Pusan and Gyeongnam. Among family members contacted. 112 ones made an appropriate response to the survey. The statistical package SAS was utilized for descriptive statistics, correlation coefficients, stepwise multiple regression, and cluster analysis. The results of the study were as follows: 1) Demographic and social characteristics of the patients surveyed are female 81.3%, average age 81.4 years, lack of schooling 83.0%, spouse dead 73.2%, having no other disease 58.9%, average duration of dementia 3.8 years, no medical treatment for dementia 84.8%, good married life 40.2%, and primary care given by daughter-in-law 49.1%. 2) Aggressive Psychomotor Behavior(APB) was observed in a way statistically meaningful in case that primary care was given by daughter-in-law, while Nonaggressive Psychomotor Behavior(NPB) was in case of good married life and primary care given by other than daughter-in-law and spouse. Verbally aggressive behavior (VAB) was observed in groups of female, spouse dead, bad married life, and daughter-in-law's primary care. As for Passive Behavior(PB), it was observed in case that patients had educational background of not less high than middle school and that they were having medical treatment. Functionally Impaired Behavior(FIB) was observed in age group of 60-69 and more than 90, in patients' group having no other disease, and in case that the duration of dementia was not less than 5 years. 3) Premobid Neuroticism(N) showed positive correlation with APB and VAB, while Openness (O) did negative correlation with PB. Agreeableness (A) was proved to have positive correlation with PA and FIB, but to have negative correlation with APB and VAB. In addition, Conscientiousness(C) showed negative correlation with APB and VAB. 4) The worse the psychosocial environment was, the more NPB and VAB were observed. 5) APB was explained 24% by C and primary care-giver, while NPB was explained 28% by psychosocial environment, having other disease or not, and married life. VAB was explained 40% by A. sex, and married life. On the other hand PB was explained 33% by O, A. N, and having medical treatment or not. But any significant factor was not found to explain FIB. 6) A cluster analysis was performed on disturbing behaviors of demented elderly staying at home. It enabled to regroup the demented elderly in 5 patterns: high scored in NPB, high scored in FIB. high scored in NPB and VAB, moderately scored in most disturbing behaviors, and low scored in all areas. In conclusion, disturbing behaviors of demented elderly not only reflect their premorbid personality in the past, but also are affected by their present psychosocial environment. Therefore, it is necessary to encourage and respond them with understanding their disturbing behaviors in relation to their past premorbid personality. In addition, it is important to provide them better psychosocial environment in order to reduce their disturbing behaviors.

Korea's national income statistics have been compiled by the Bank of Korea since 1953. However, there is a break in the time series. The current time series (1970 onward) is based on the '1993 SNA (System of National Accounts)' suggested by the UN, and the previous time series (1953~1970) was based on the '1953 SNA'. The difference between the previous and current time series is 4.8% in 1970 when the two series overlap. The difference is even greater in terms of comparisons across industries. In addition, it has now become even more difficult to connect the current and the previous time series because, in 2009, the Bank of Korea introduced a chain weighted method for calculating the current time series (1970 onward). Under the chain weighted method, the time series underwent substantial modification; for instance, the economic growth rate during 1970~2005 is 0.9%p higher than the rate under the general method. This paper applies chain weighted values and the '1993 SNA' to the previous time series (1953~1970) by utilizing various national account manuals published by the UN and previous Korean input-output tables in order to calculate a long term time series from 1953 to 2010 based on the same criteria as the current time series (1970 onward). In the revised time series, it appears that 1953 GDP at current basic prices is 3.5% higher and the growth rate for the period of 1953~1970 is 1.5%p higher each year than under the previous time series. Under the revised time series the size of the Korean economy as of 2010 is 50-fold bigger than that of 1953. In terms of industries, manufacturing and SOC show significant expansion whereas the extent of that of the service industry is relatively small.

The purpose of this study was to examine the comparison of physique with physical fitness according to TBS (Talented-Educational in Sport) program by H University in 2009-2011. For this study, 668 elementary students (2009: 297, 2010: 194, 2011: 177 or 1st: 506, 2nd: 104, 3rd: 58) were collected who aged 7 to 13 living in Seoul and Gyeonggi area. The subjects were measured on physique variables (5) and physical fitness variables (7). Mean comparisons (ANOVA) were conducted for each gender in order to compare the mean differences among attendance number. For association analysis, Pearson correlation coefficient was used to find association between the physique and physical fitness variables. Some physical fitness variables (sit up, half squat jump, side step, standing long jump, flexibility in male children; sit up, half squat jump, side step in female children) increased significantly in the attendance number but the physique variables did not. The results show that TES program was effective on the physical fitness variables (muscle endurance & agility) in sports talent children.

Purpose : The purpose of this study was to analyze the prehospital care report prepared by EMS squads of 119 center in Gyeonggi area and to identify the status of prehospital care activities, problems and improvement possibilities of the emergency care. Method : Five hundred copies of prehospital care report prepared by EMS squads in thirty-eight 119 centers under 18 fire stations in Gyeonggi area from March to April in 2008 were randomly chosen for the analysis. Data abstracted according to the purpose of the study were input and the analysis of prehospital care activities were performed using SPSS-WIN(ver. 16) statistics package. Results : 1. Total 500 cases of prehospital emergency care activities were reviewed. By sex, females were 219 (43.8%) and males were 281 (56.2%). The places of reporting were home (57.8%). According to the type of emergency, 281 cases (56.2%) were caused by disease and 291 (43.8%) were from other causes such as traffic accidents or incidental injuries. 2 The average time needed for the 119 EMS squad to arrive at the scene after being reported was 7.29 minutes. The time used at the scene for the emergency care was 7.3 minutes in average and the time to arrive at the hospital was 25.4 minutes in average. 3. In patient evaluation, in 68% of the cases more than two vital signs were measured at one time and emergency patients were 31%, and non-emergency patients were 69%. 4. In one EMS activity, average 2.15 cases of emergency care were provided to a patient. The cases where two kinds of emergency care were given were 14.4%, which is the most frequent cases. When reviewing the details of the emergency cares given to the patient including multiple cares, trivial cards (taking it easy and giving comfort) were the most frequent one as 40.6% and the medical direction of the doctor was given in only one case out of 500 cases. 5. In patient evaluation and emergency care, vital signs were provided to emergency patients at significantly higher rate comparing to the non-emergency patients. The number of emergency care performance was significantly higher in emergency cases. In emergency dispatch, the cases that EMT (1st class) was on board was 86.2%. When comparing the cases when the 1st class EMT was on board and otherwise, the cases with the presence of 1st class EMT showed more vital signs were detected but there was no significant difference in the number of emergency cares provided. Conclusion : It seemed that the on-scene emergency care did not satisfy the expectations. So it is necessary to enforce the cooperation between the elements, the qualifications of the 119 EMS squads and to improve the prehospital working environment in order to provide the better medical service at any time.

A self-administered questionnaire survey and face-to-face interviews were conducted on 150 local residents belonging to seven villages, 160 visitors and 86 experts in order to analyze the attitudes of groups of local residents, visitors as well as experts toward the development plan of Sobaeksan Jarak-gil. Reliability analysis and one-way ANOVA were performed on the data collected by a questionnaire survey using IBM SPSS Statistics 20.0 after coding. The Duncan Test was conducted as a post-hoc test. Based on the analytical results, in economic terms, the expert group expected an increase in income, improvement in living standards and increase in expenditure for the maintenance of local infrastructure. In environmental terms, the visitor group was highly concerned about the disruption of the local natural environment and ecosystem, destruction of local properties and landscape, increase in water/soil/air pollution and increase in solid waste and noise. In social and cultural terms, the expert group had higher expectation for excavation of traditional cultural properties, instillation of local patriotism and pride, and the visitor group was highly concerned about a rise in crime, destruction of indigenous culture/increase in imitations, and induction of conflicts between residents. It is estimated that these results will be used as basic data for establishing the development plan of the mountainous ecological trail reflecting opinions of various groups.
