Carbon dioxide, included in the flue gas from the combustion of fossil fuel, was known as a representative green house gas and various removal and utilization technologies of it has been studied for the prevention of global warming. This study was performed as an effort to find out a method to reuse carbon dioxide separated from flue gas by magnetite powder. Magnetite powder was synthesized using various oxidizers and alkalinity controlled aqueous solutions of $FeSO_4{\cdot}7H_2O$ and NaOH at 50, 80, 90, $100^{\circ}C$ and analyzed by XRD and SEM. The analysis results showed that magnetite powder synthesized at higher alkalinity and temperature had crystalline spinel and cubic structure. The reduction by hydrogen and the oxidation by carbon dioxide of synthesized powder were studied by TGA. The results showed that magnetite powder synthesized at low alkalinity and temperature was non-cubical amorphous but crystalline and cubical at high alkalinity and temperature. Comparing magnetite powders synthesized using oxidants(air and oxygen) and nitrogen, magnetite powder using more oxygen containing oxidant synthesized more crystalline magnetite powder. The experimental results of redox reaction of the synthesized magnetite powder showed that the reduction by hydrogen and the oxidation by carbon dioxide were seldom observed below $400^{\circ}C$ and observed well at $500^{\circ}C$. Magnetite powder synthesized at $100^{\circ}C$ and alkalinity(molal concentration ratio of $FeSO_4{\cdot}7H_2O$ to NaOH) of 2.0 using $O_2$ showed the highest reduction of 27.15 wt％ and oxidation of 26.73 wt％, especially at reaction temperature of $500^{\circ}C$.

The aim of the present study was undertaken to investigate the association between diagnostic indices of metabolic syndrome(MetS) with carotid intima-media thickness using ultrasonography. The participants in the study were 315 male employees without carotid atherosclerosis and other cardiovascular disease. This study was approved by the Institutional Review Board of Occupational Safety and Health Research Institute. Written informed consent for the participants in this study was obtained from all individuals. Anthropometric parameters and biochemical characteristics were done using each specific equipments and the NCEP-ATP III criteria were used to define MetS. They were examined by B-mode ultrasound to measure the carotid intima-media thickness(carotid IMT) at the near and far walls of common carotid and bifurcation(bulb). The mean carotid IMT was $0.739{\pm}0.137\;mm$ and it's thickness significantly increased with the increase in age. Also, amounts of systolic and diastolic blood pressure, triglyceride and fasting glucose were significantly increased with the increase in age. Carotid IMT were significantly correlated with BMI(r=0.170, p=0.004), systolic(r=0.148, p=0.011) and diastolic blood pressure(r=0.123, p=0.036) and HDL-cholesterol(r=-0.164, p=0.005). On multiple logistic regression analysis for the diagnostic indices of MetS, carotid IMT were significantly associated with blood pressure(OR=4.220, p<0.01) and MetS(OR=1.301, p<0.05). The results indicate that blood pressure and MetS are important risk factors for carotid atherosclerosis.

The occurrence of acute respiratory infections caused by the influenza virus are particularly high during the winter season in Busan, Korea. In 2004 and 2005, a study of the rate of occurrences of the influenza virus was conducted. The results reveal that in 2004, of the 1,869 people with an acute respiratory infection that 154 (8.2%) people were infected by the influenza virus. In 2005, of the 1,579 people infected with an acute respiratory infection that 19 people (1.2%) were infected with the influenza virus. The study shows a decrease in the numbers of an influenza virus infection from 2004 to 2005. Data was collected by inspecting throat swabs and nasal discharge from those with an acute respiratory infection. Further inspection of the throat swab and nasal discharge from the infected individuals during 2004 and 2005 study show the occurrence of the different types of influenza virus in the population: 6 cases (3.5%) of influenza type A/H1N1, 129 cases (74.5%) of A/H3N2, and 38 cases (22.0%) of type B. The study conducted in 2004 and 2005 reveal that children between the ages of two and five were more likely to be infected than any other age group. In the study, about 62.2% of the infected individuals were between two and five years old. The detection rates between males and females are similar. However, it is notable that females are slightly more likely to develop an acute respiratory infection caused by the influence virus compared to their male counterparts.

Purpose: The purpose of the present study was to investigate needs and satisfaction on the medical services of cancer patients in Jeju Special Self-Governing Province. Methods: Total 174 cancer patients, who visited at the clinic of Jeju National University Hospital, submitted informed consent and participated in this study from July 13 to July 30, 2009. Self questionnaire was used and data were analyzed with Kolmogorov-Smirnov test, Mann-Whitney U test, ANOVA, and Kruskal-Wallis test. Results: Participants expressed the needs of most economical support (3.38 out of 4), followed by counseling of treatment plan (3.22), information of disease (3.07), and disease management except cancer (2.97). Participants were satisfied most with religious counseling (3.41), followed by nursing service support (3.39), employment counseling (3.26), and counseling for family or interpersonal relationships (3.26). The satisfaction of economical support was the lowest (1.98). Satisfaction of men was higher than women, and needs in patients who were living with children was the highest. Patients who were living alone or with children showed the lowest satisfaction about the medical services. There were no significant differences in the general characteristics, however, participants who were older than 60 years of age or had higher income showed lower needs and higher satisfaction. There were no significant differences in the medical characteristics, however, thyroid cancer patients and patients who were treated with radiation therapy or transarterial embolization showed low satisfaction. Conclusion: Cancer patients seemed to need more economical support, information of treatment or disease, and symptom management. Furthermore, there were various needs about the services, depending on family formation or economical support of patients. Therefore, it is certain that patients who were suffering from other cancers, except the 5 major cancers, needed more services. In conclusion, continuous and systemic policy to consider patient's characteristics and needs are needed in community as well as health care system.

The purpose of this study was to investigate the effect of the type and measurement location of a fabric strain gauge sensor on the detection performance for respiratory signals. We implemented two types of sensors to measure the respiratory signal and attached them to a band to detect the respiratory signal. Eight healthy males in their 20s were the subject of this study. They were asked to wear two respiratory bands in turns. While the subjects were measured for 30 seconds standing comfortably, the respiratory was given at 15 breaths per minute were synchronized, and then a 10-second break; subsequently, the entire measurement was repeated. Measurement locations were at the chest and abdomen. In addition, to verify the performance of respiratory measurement in the movement state, the subjects were asked to walk in place at a speed of 80 strides per minute(SPM), and the respiratory was measured using the same method mentioned earlier. Meanwhile, to acquire a reference signal, the SS5LB of BIOPAC Systems, Inc., was worn by the subjects simultaneously with the experimental sensor. The Kruskal-Wallis test and Bonferroni post hoc tests were performed using SPSS 24.0 to verify the difference in measurement performances among the group of eight combinations of sensor types, measurement locations, and movement states. In addition, the Wilcoxon test was conducted to examine whether there are differences according to sensor type, measurement location, and movement state. The results showed that the respiratory signal detection performance was the best when the respiratory was measured in the chest using the CNT-coated fabric sensor regardless of the movement state. Based on the results of this study, we will develop a chest belt-type wearable platform that can monitor the various vital signal in real time without disturbing the movements in an outdoor environment or in daily activities.

The purpose of this study was to identify the degree of sexual adjustment and quality of life in married men with spinal cord injuries and to furnish primary data to sexuality rehabilitation nursing practice which can lead to ideal sexual life and quality of life those men with SCI. Seventy married men with SCI were conveniently sampled in Kwangju, Suncheon, Mokpo and Seoul for responding the questionnaire, which was based on this research. With the research scale, SIS (Sexual interest and satisfaction) by Siosteen et al.(1990) and SB(Sexual behaviour) by Kreuter et al.(1996) were used for the measurement of sexual adjustment. And, for measuring quality of life was used SCI QL-23(Spinal cord injury of life-23) scale by Lundqvist et al.(1997). Data were collected from January 20 to March 20, 1999, using a structured questionnaire. A hundred volumes of questionnaire were used. and 85 volumes were collected, 70 volumes were used as research data after excluding 15 volumes unsuitable to data analysis. The obtain data were analysed using percentage, t-test, ANOVA, Duncan test, and Pearson's correlation by SAS PC+ program. The results were as follows: 1. The mean score of sexual interest and satisfaction of the subjects was 8.42. out of 18. The ways of their sexual behavior after spinal cord injuries were embracing and caressing (62.9%), kissing(58.6%), caressing breast with hands (55.7%), caressing breast with hands (52.9%), caressing genitals with hands (37.2%), caressing genitals with mouth(30.0%) and sexual intercourse (18.6%). The mean score of quality of life was 52.53 out of 100. 2. Age(F=3.24, p=.045) and caregiver (F=4.02, p=.022)were major variables which reveals significant differences in terms for sexual interest and satisfaction. The later results on Duncan's test showed that subjects who were in their 30s or 40s were significant higher than subjects whose age were in their 50s in their sexual interest and satisfaction. Also subjects with their spouse's care or mother's care were higher than those with other's care. 3. Subjects with incomplete paraplegia were higher than those with the complete paraplegia in sexual interest and satisfaction (F=3.01, p=.036). 4. Variables that showed the significant differences in the quality of life were education(t=2.860, p=.007) and period of marriage(t=2.125, p=.037). and occupational status(t=-2.161, p=.034). High school graduates, those who married before spinal cord injuries and those who didn't have occupation were higher than the other subjects. 5. Variables that revealed significant differences in the quality of life were time passage after spinal cord injuries(F=8.72, p=.001) and injured level of spinal cord(F=3.32, p=.042). Duncan's test showed that subjects who had lived for less than 4 years were higher those with time passage of 5-9 years and 10 years. Also subjects with lumbar injuries were higher than those with thoracic injuries in terms of quality of life. 6. There was negatively correlated between sexual interest and satisfaction and quality of life(r=-.256, p<.05). As a result of these findings sexuality rehabilitation for individuals with SCI was very important issue for their quality of life. Thus, registered nurses who care clients with SCI should activily participate in the client's sexual needs. Also, various sexual behaviors as well as sexual intercourse should be encouraged for the sexual adjustment of client's with SCI.

Objectives : This study was to provide normative data of Korean version of DSI(K-DSI), a sensitive measure of relatively minor stressors that could be administered daily. Methods : K-DSI was administered in 524 adults, age of 19 or over, daily for 1 week. On the seventh day, Becks Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI), and Social Readjustment Rating Scale(SRRS) were also given to test the convergent validity. Analyses(ANOVA or t-test) were conducted to examine the potential effects of demographic variables on K-DSI score. Internal consistency for reliability and Pearson's corelation coefficient with BDI, STAI, SRRS for convergent validity were computed. Percentile scores were calculated for daily and weekly K-DSI Event, Impact and I/E Ratio scores. Results : K-DSI scores in women were higher than those in men. According to age and educational level, the younger and the higher educational level the normative groups were, the higher were K-DSI scores. Among the 5 categories of the inventory, the category of cognitive stressors was highest. Internal consistency of K-DSI(Cronbach's $\alpha$) was .99. Daily and Weekly events and impacts scores were significantly correlated with the scores of State-Trait Anxiety Inventory, Social Readjustment Rating Scale, and Beck Depression Inventory. 75 percentile scores of the daily/weekly Events, Impacts, and I/E ratio were 17/118 - 124, 57/368 - 389 and 3.48 - 3.49/3.47 - 3.48 respectively. And 95 percentile scores of daily/weekly Events, Impacts, and I/E ratio were 57/151- 161, 405/1038 - 1122, and 4.72 - 4.86/4.46 - 4.56 respectively. Conclusion : Reliability and validity of K-DSI were tested satisfactorily. Authors presented the normative data of K-DSI for Koreans. K-DSI could be a useful measure in clinical settings or researches to assess the minor stressors frequently experienced in everyday life.

This study was carried out on thirty men to define the association of inflammatory markers with physiological factors on one-time aerobic exercise (for 15 min. Post-exercise interleukin-6 (IL-6), mean corpuscular hemoglobin concentration (MCHC), heart rate (HR), systolic blood pressure (SBP), and pulsatility and resistance index of middle cerebral artery (PI and RI, respectively) levels were elevated compared to those measured pre-exercise. Total leukocyte and platelet counts, high-sensitivity C-reactive protein (hs-CRP), free radical (FR), and low density lipoprotein cholesterol (LDL) levels tended to decrease after exercise. Pre-exercise IL-6 levels were positively correlated with pre-exercise SBP levels, while post-exercise IL-6 level was positively correlated with post-exercise PI and RI levels. Post-exercise, hs-CRP levels were negatively related to SBP and HR. Pre-exercise, FR levels were positively associated to SBP, DBP, and HR. Post-exercise FR levels were negatively related to the post-exercise blood flow velocity in middle cerebral artery. Pre-exercise erythrocyte indices (RBC, MCV, MCH, and MCHC levels) were in inverse proportion to pre-exercise IL-6 levels. Post-exercise FR levels were inversely related to post-exercise total leukocyte, lymphocyte, monocyte, and MCH levels. Pre-exercise $Mg^{++}$ levels were in inverse proportion to pre-exercise IL-6, hs-CRP, or FR levels. These findings suggest that one-time aerobic exercise offers a significant relationship between inflammatory markers and some biochemical markers or electrolytes. Further studies need to be carried out for investigation of differences between genders or age groups following one-time or regular aerobic exercise.

It was main objectives to find the learners characteristics and educational effects of cyber agricultural technology courses in RDA. For the research, it was followed by literature reviews and internet based survey methods. In internet based survey, two staged stratified sampling method was adopted from cyber training members database in RDA along with some key word as open course or certificate course, and enrollment years. Instrument was composed through literature reviews about cyber education effects and educational effect factors. And learner characteristics items were added in survey documents. It was sent to sampled persons by e-mail and 316 data was returned via google survey systems. Through the data cleaning, 303 data were analysed by chi-square, t-test and F-test. It's significance level was .05. The results of the research were as followed; First, the respondent was composed of mainly man(77.9%), and monthly income group was mainly 2,000,000 or 3,000,000 won(24%), bachelor degree(48%), fifty or forty age group was shared to 75%, and their job was changed after learning(12.2%). So major respondents' job was not changed. Their major was not mainly agriculture. Learners' learning style were composed of two or more types as concrete-sequential, mixing, abstract-random, so e-learning course should be developed for the students' type. Second, it was attended at 3.2 days a week, 53.53 minutes a class, totally 172.63 minutes a week. They were very eager or generally eager to study, and attended two or more subjects. The cyber education motives was for farming knowledge, personal competency development, job performance enlarging. They selected subjects along with their interest. A subject person couldn't choose more subjects for little time, others, non interesting subject, but more subject persons were for job performance benefits and previous subjects effectiveness. Most learner was finished their subject, but a fourth was not finished for busy (26.7%). And their entrying behavior was not enough to learn e-course and computer or internet using ability was middle level as software using. And they thought RDA cyber course was comfort in non time or space limit, knowledge acquisition, and personal competency development. Cyber learning group was composed of open course only (12.5%), certificate only(25.7%), both(36.3%). Third, satisfaction and academic achievement of e-learning learners were good, and educational service offering for doing job in learning application category was good, but effect of cyber education was not good, especially, agricultural income increasing was not good because major learner group was not farmer, so they couldn't apply their knowledge to farming. And content structure and design, content comprehension, content amount were good. The more learning subject group responded to good in effects, and both open course and certificate course group satisfied more than open course only group. Based on the results, recommendation was offered as cyber course specialization before main course in RDA training system, support staff and faculty enlargement, building blended learning system with local RDA office, introducing cyber tutor system.
