Objective : This study aims to identify the effect of an occupational therapeutic intervention program including horticultural therapy on cognition and daily living performance of the elderly with dementia. Methods : For the purpose, the study measured the changes before and after the therapy, targeting sixteen women with dementia who were living in nursery facilities. We used MMSE-K to analyse the cognition, and evaluated daily living performance using K-MBI(p<.05). Results : The results of the study were presented as follows: 1. To identify changes of MMSE-K before and after the therapy between the control and test groups. As a result, it was discovered that MMSE-K of the control group was $16.25{\pm}1.38$ before the therapy and $16.00{\pm}.92$ after the therapy, which indicated no significant differences, but MMSE-K of the test group was $16.00{\pm}1.51$ before the therapy and $17.87{\pm}1.35$ after the therapy, which was statistically significant (p<.05). 2. To identify changes in daily living performance(K-MBI) between the two groups before and after the therapy, and it was discovered that scores of the control group were $74.00{\pm}1.30$ before the therapy and $74.25{\pm}1.16$ after the therapy, which showed no significant difference, but those of the test group were $73.75{\pm}1.28$ before the therapy and $76.37{\pm}1.30$ after the therapy, which was statistically significant(p<.05). Conclusion : Based on the results above, it was demonstrated that the an occupational therapeutic intervention program including horticultural therapy had a positive effect on cognition and daily living performance of elderly women with dementia and it is suggested that the results can be used as basic data for clinical intervention of the elderly with dementia.

In this study, we investigated factors for affecting pneumothorax in percutaneous needle aspiration biopsy of lung lesions. This research were conducted at University Hospital in Daejeon from August 2007 to May 2008. Total 104 patients between the ages of 25~85 who had focal lung lesions were grouped in terms of the tumor location, tumor size, depth of lesion, gender, age, biopsy time, and the number of biopsies. Then, their correlations with pneumothorax were studied. The incidence of pneumothorax according to the positions showed 27.3% in the right lower lobe, 24.3% in the right upper lobe, 15% in the left lower lobe and 12% in the left upper, respectively. In addition, the incidence by lesion size showed 24.0% in 0~2.0 cm, 18.2% in 2.1~4.0 cm, above 20.0% in 4.1 cm respectively. The probabilities of pneumothorax was 6.7% at 0 cm depth of lesion, 24.2% at 0.1~2.0 cm and greater than 26.8% at 2.1 cm. By gender differences, we found that probability of incidence of pneumothrax is 21.7% for male and 17.1% for female. According to age, pneumothorax occurred in 25% in the group of less than 40-years-old, 11.7% in 41~50 years, 14.3% in 51~60 years, 24.1% in 61~70 years old and 24.1% in over 70 years. According to the time of biopsy, the incidence of pneumothorax was 3.8% from 0 to 10.0 minutes, 18.9% from 10.1 to 20.0 minutes and 40% more than 21 minutes.

Helicobacter pylori is now recognized as causative agent of chronic gastritis and peptic ulcer, and strongly associated with development of gastric carcinoma. With development of sensitive and specific serologic tests to identify individuals infected with Helicobacter pylori, the epidemiologic study of this diseases has been investigated. But it's transmission route is not established, yet. The purpose of this study is to measure the prevalence of Helicobacter pylori infection in healthy children and young adults and to evaluate related factors for Helicobacter pylori infection in Korea. The seroprevalence of Ig G antibodies to Helicobacter pylori was determined using a Enzyme Linked Immunosorbent Assay and we obtained the information, such as demographic characteristics, monthly household income, numbers of family members in the house, numbers of persons using same room, type of house, and type of drinking water through the questionnaire survey. The observed overall seropositivity rate was 25.7%. The rate is increased progressively from 5.8% in the age group $1\sim3$ years to 44.4% in the age group $20\sim29$years($\chi^2$ for trend, p<0.001). Especially, the rate increased steeply from 6.5% in the age group $4\sim6$ years to 20.8% in the age group $7\sim9$ years, and this suggested that elementary school age was the major acquisition time of Helicobacter pylori infection. In multivariate logistic regression model, age, numbers of family members in the house, and type of house was statistically significant variables for Helicobacter pylori infection. Each odds ratio(93% CI) were as follows; base to age group $1\sim9$ years, age group $10\sim19$ years $3.6(2.0\sim6.4)$, age group $20\sim29$ years $7.3(4.1\sim13.1)$ and base to group of $1\sim3$ family members, group of $4\sim5$ family members $2.1(1.1\sim4.0)$, group of 6 or more family members $2.7(1.3\sim5.4)$ and base to apartment, single and multihouse $1.9(1.1\sim3.5)$. Sex, monthly household income, numbers of persons using same room, and type of drinking water was not statistically significant for Helicobacter pylori infection.

This study was carried out to investigate the effects of wormwood (Artemisia sp.) addition on the growth performance, nutrients utilization and abdominal fat deposition of broiler chickens. Two hundred twenty five and two-day old Arboracre strain male commercial broiler chicks were distributed to 5 treatments with wormwood supplementation levels; C(O%), $T_1$ (1%), $T_2$ (3%), $T_3$ (5%), and $T_4$ (10%) and with 3 replications each with 5 birds for five weeks. Body weight gain during the experiment was improved in $T_1$ (1723.0g) compared with that of $T_3$ (1557.7g) and $T_4$ (1450.7g) (P<0.05). Feed intake was significantly (P<0.05) increased as the levels of wormwood addition increased (C: 2653.8g, T1: 2852.0, $T_2$: 2900.3, $T_3$: 2900.7g, T4: 2954.7g). Feed conversion rate (feed/gain) was significantly (P<0.05) increased as the levels of wormwood addition increased (C: 1.55, $T_1$: 1.66, $T_2$: 1.70, $T_3$: 1.86, $T_4$: 2.04). The days reaching to 2.0kg of body weight were expected to be 43.2 days in control, whereas those of group T1 were reduced to 42.6 days by 0.6 day from control. Nutrient utilization and abdominal fat deposition in the experiment were significantly decreased (P<0.05) and small intestine contents in the broilers was significantly increased (P<0.05) as the levels of wormwood addition increased. Therefore, although there was no significant improvement for the performance of broiler chickens with the dietary supplementation of wormwood meal, less than 1% addition of wormwood to broiler diets might have beneficial for human health by reducing the abdominal fat deposition of the broiler chicknens.

This study was designed obtain and early detection the workers exposed to excessive copper dust and also to present biological exposure index. The exposed group consisted of 62 male workers at the metallurgy workplaces. To evaluate the degree of individual exposure the copper dust, each personal air sampling was collected. Biological exposures in the exposed group was quantified for the blood and urine copper levels using flameless atomic absorption spectrophotometer. The control group consisted of 70 male adults with the history of nonexposure to copper by the inhalation occupationally. The average concentration of copper in blood and urine of the exposed group was $49.44{\pm}8.90(29.05-80.63){\mu}g/dl$, $39.99{\pm}11.04(29.62-80.63){\mu}g/l$ respectively. The average concentration of air borne copper was $0.48{\pm}0.31(0.03-1.18)mg/m^3$. The average concentration of blood and urine copper in the control group was $42.93{\pm}5.84(25.05-57.85){\mu}g/dl$, $33.02{\pm}13.38(12.00-82.05){\mu}g/l$ respectively. The difference observed in the average concentration of blood and urine copper of the exposed and control groups was statistically significant seperately (blood copper, p<0.05 ; urine copper, p<0.05). The relationship between the individual exposure concentration of air borne copper and the concentration of the blood and urine copper was statistically significant, respectively (blood copper, r=0.54, p<0.05 ; urine copper, r=0.37, p<0.05). The relationship between the working duration and the concentration of blood and urine was not statistically significant respectively (blood copper, r=0.14 ; urine copper, r=0.12). The relationship between the age and the concentration of blood and urine copper was statistically not significant respectively (blood copper, r=013 ; urine copper, r=-0.06). The relationship between blood and urine copper concentration in the exposed group was statistically significant (r=0.62, p<0.05), and the relationship between blood and urine copper concentration in the control group was also statistically significant (r=0.39, p<0.05).

Objective : Postpartum depression(PPD) was known to be caused by many factors including various psychosocial risk factors. This study was performed to identify the psychosocial risk factors for ppd, preliminarily in Korea. Methods : A group of 119 postpartum women, each of whom was at 6 to 8 weeks after delivery was identified at the time when they visited to the child health clinic or postnatal check-up clinic. The risk factors were surveyed by the self-reported questionnaire. The items of questionnaire were consisted of known risk factors in other studies and other possible stress-related factors. PPD was assessed by the Edinburgh Postnatal Depression Scale(EPDS) and the degree of postpartum depression was determined by its score. Results : 16 women(13.45%) in the high risk group were diagnosed as PPD among the 119 women. Risk factors including past experience of depressive symptoms and low level of marital satisfaction were founded more frequently in women in the high risk group than in the low risk group. The score of EPDS was significantly high in the group who experienced depressive symptoms in the past, anxiety or depression during pregnancy, stressful life event during the period of recent pregnancy and postpartum, and who had low level of marital satisfaction. There was a positive correlation between age and the score of EPDS. However, the postpartum depressive symptoms were not influenced by the level of education, job, retirement due to pregnancy and delivery, wanted or unwanted pregnancy, delivery method, feeding method, the hospitalization of infant, expected and real gender of infant. Conclusion : These results suggest that PPD is quite frequent at postpartum period. Various risk factors contribute to the development of PPD. If clinicians pay attention to the risk factors of PPD and give appropriate psychiatric intervention to the mothers during pregnancy and postpartum, it will be easy for the clinicians to recognize and treat PPD in the early stage.

Impervious covers(IC) are artificial structures, such as driveways, sidewalks, building's roofs, and parking lots, through which water cannot infiltrate into the soil. IC is an environmental concern because the pavement materials seal the soil surface, decreasing rainwater infiltration and natural groundwater recharge, and consequently disturb the hydrological cycle in a watershed. Increase of IC in a watershed can cause more frequent flooding, higher flood peaks, groundwater drawdown, dry river, and decline of water quality and ecosystem health. There has been an increased public interest in the institutional adoption of LID(Low Impact Development) and GI(Green Infrastructure) techniques to address the adverse impact of IC. The objectives of this study were to construct the modeling site for a samll urban watershed with the Storm Water Management Model(SWMM), and to evaluate the effect of various LID techniques on the control of rainfall runoff processes and non-point pollutant load. The model was calibrated and validated using the field data collected during two flood events on July 17 and August 11, 2009, respectively, and applied to a complex area, where is consist of apartments, school, roads, park, etc. The LID techniques applied to the impervious area were decentralized rainwater management measures such as pervious cover and green roof. The results showed that the increase of perviousness land cover through LID applications decreases the runoff volume and pollutants loading during flood events. In particular, applications of pervious pavement for parking lots and sidewalk, green roof, and their combinations reduced the total volume of runoff by 15~61 % and non-point pollutant loads by TSS 22~72 %, BOD 23~71 %, COD 22~71 %, TN 15~79 %, TP 9~64 % in the study site.

Purpose: Regardless of treatment, brain metastases are associated with a poor prognosis. We aimed to investigate the clinical characteristics of cancer patients with brain mestastases they after admission into a hospice unit and knowing they have received appropriate hospice and palliative care. Methods: We retrospectively reviewed the medical records in 40 cancer patients with brain metastases they after admission into a hospice unit from March in 2003 to March in 2005. Results: There were 20 males (50%) and 20 females (50%), and the median age of the patients was 64 years. The most common cause of brain metastases was lung cancer (22 patients, 55%), followed by stomach cancer (5, 13%) and breast cancer (3, 8%). Sixteen patients (40%) have never been teated and 20 patient have received the chemotherapy for the primary cancer. The most common symptom of cancer patients with brain metastases is headache (12 patients, 30%), followed by mental change (10, 25%), focal weakness (9, 23%) and convulsion (4, 10%). The most prevalent cause for admission was mental change (13 patients, 33%), followed by pain (9 patients, 23%). The reasons for hospice and palliative care were through recommendation of physician (1 patient, 3%), patient and family self (14, 35%) and the others (25, 62%). Twenty five of the others has been referred to hospice and palliative care during conservative management after referral and enrolled at hospice unit. The median hospitalization was 19 days and median survival in hospice and palliative care was 41 days. The median survival was 87 days from the day when the cancer patients have been diagnosed as brain metastases to death. Conclusion: The duration of hospice and palliative care was not enough to care the cancer patients with brain metastases. We suggest physicians, patients and family need the education and promotion for effective hospice and palliative care.

Objectives : As medical science develops, survival rate of cancer patients rises. Therefore, psychologic understanding and improving quality of life in cancer patients is getting greater significance. The Object of this study is to investigate sociodemographic and clinical characteristics, psychopathology, self esteem and quality of life in cancer patients and to provide useful information for therapeutic approach to cancer patients. Methods : The subjects were 41 patents who had been treated by radiotherapy and 20 normal people. Sociodemographic information and clinical characteristics of cancer patients were investigated, and SCL-90R for psychopathology, Rosenberg Self-esteem Scale for self esteem, WHOQOL-BREF for quality of life were administered to subjects. The results of both groups were compared and analysed, and correlation between variables were evaluated. Results : 1) The tendency of Somatization, obsession-compulsion, depression, anxiety, hostility, phobia, psychosis in cancer group were higher than normal group. Especially, somatization and anxiety in cancer group were significantly higher than normal group. 2) Self esteem and quality of life in cancer group were significantly lower than normal group. 3) No significance were found in comparison of psychopathology, self esteem and quality of life according to sociodemographic variables. Among clinical characteristics, higher somatization was shown in case of more weight loss, and higher somatization and lower quality of life was shown in the presence of pain. 4) Higher anxiety was significantly associated with lower self esteem, and Higher somatization and anxiety was significantly associated with lower quality of life. Conclusion : Cancer patients had various kinds of psychopathology, low self esteem and low quality of life. In particular, somatization and anxiety, self esteem and pain were found to be important factors to quality of life of cancer patients. Therefore, management of psychopathology, improving self esteem, pain control is necessary to improve quality of life in cancer patients.

Purpose: The purpose of the study was to identify the nutrition knowledge, dietary attitudes of guardians, and nutritional status of infants and toddlers as well as the relationships between these variables. Methods: The participants were selected among applicants for low-income family financing provided by the government and included 115 infants and toddlers as well as their guardians. Demographic data, nutrition knowledge, dietary attitudes, and nutrition intakes were assessed using a self-administered questionnaire, biochemical examination, and 24 Hour-Recall method. Results: The score for guardians' nutrition knowledge was 12.97 points of a possible 15, and the score for dietary attitudes was 53.38 points of a possible 75. The nutrition knowledge and dietary attitudes showed significant differences by education level (p < 0.05) and family structure (p < 0.05). Energy intakes of subjects aged 6 ~ 24 months and over 25 months were lower than the DRI for Koreans. The intakes of carbohydrates, protein, and fat of subjects aged 6 ~ 24 months and over 25 months showed no significant differences by level of nutrition knowledge or dietary attitudes. The intake of Ca of subjects aged over 12 months showed significant differences by level of nutrition knowledge (p < 0.05). The intakes of Thiamin of subjects aged 6 ~ 11 months and P of subjects aged over 12 months showed significant differences by level of dietary attitudes (p < 0.05). There was a small positive correlation between education level and nutrition knowledge as well as between dietary attitudes. Nutrition knowledge showed a positive correlation with dietary attitudes. There was a positive correlation between nutrition knowledge and Ca, Riboflavin, as well as Vit C levels. Conclusion: Therefore, it is necessary to consider an educational program for increasing the practical application of knowledge to nutrition management for improvement of nutrition intake in infants and toddlers.
