Background: The introduction of Drug Eluting Stents (DES) decreased the number of patients referred for coronary artery bypass grafting (CABG). The impact of DES on CABG (Step 1) was studied and compared with the 1-year outcome after CABG with DES (Step 2). Material and Method: Surgical results for patients who underwent off-pump CABG (OPCAB) before the introduction of DES(n=298) were compared with those who underwent OPCAB after the introduction of DES (n=288) (Step 1). Postoperative 30-day and 1-year results were also compared between the patients who underwent percutaneous coronary intervention (PCI) using DES (n=220) and those who underwent OPCAB (n=255) (Step 2). Result: Since the introduction of DES, the ratio of CABG versus PCI decreased. In the CABG group, the number of high risk patients such as elderly patients (age 62 vs. 64, p=0.023), those with chronic renal failure (4% vs. 9%, p=0.021), calcification of the ascending aorta (9% vs. 15%, p=0.043), or frequency of urgent or emergent operations (12% vs. 22%, p=0.002) increased. However, there were no differences in the cardiac death and graft patency rates between the two groups (step 1). During the one-year follow up period, the rate of target vessel revascularization (12.3% vs. 2.4%, p<0.001) and major adverse cardiac events (MACE: death, myocardial infarct, TVR) were higher in the DES than the CABG group (13.6% vs 4.3%) (stage 2). Conclusion: Introduction of DES decreased the number of patients referred for surgery, and increased the comorbidity in patients who underwent CABG. DES increased the rate of target vessel revascularization, and the occurrence of MACE during the 1-year follow-up. However, there was no difference in the incidence of myocardial infarction and cardiac death between the two groups.

The purpose of this study was to determine pattern of the stress perceived by stroke patients over time. The ultimate goal of the research is to provide data to help nurses to design the plan of nursing care of the stroke patients both in the hospital and at home. A total of 57 admitted stroke patients were collected from one general hospital in Seoul from June, 12 to September, la, 1993. The data were collected for three phases(within one week after leaving the hospital). The tools for this study, three scales were used ; Stress scale developed by the investigator. Constitution classifing scale designed by Kho(1984), and Self-care measuring scale by Kang(1984). Data were analyzed in four steps using statistical analysis. First, demographic data were determined by descriptive statistics. Second. the pattern of stress perceived by stroke patients across three phases was measured using repeated measures ANOVA. Third, stress of stroke patients classified by constitution, paralyzed area. and attack frequency were measured using ANOVA or t-test, and the pattern of stress by group over time was determined using paired t-test in post hoc test. Fourth. Pearson correlation coefficients were calculated to determine the relationship between the stress and self-care activities. The results of this study are ; 1. The pattern of stress across three phases ; There was a decrease of the stress across three phases. In general. psychological stress as the highest among three phases(F=36.92. P=.000). There was a statistically significant difference of the physical stress(F=34.55, p=.000), the psychological stress (F=15.49, p=.0005) and the social stress (F=24.71. p=.000) among three phases. There was a statistically significant difference of the stress between the first phase (on admission) and the second phase(before leaving the hospital) and was a decrease of the stress (t =6.36. p=.000). 2. The pattern of stress of stroke patients classified by constitution across three phases ; Stroke patients classified as So-Eum perceived the highest stress among three groups(Tae-Eum, So-Eum. So-Yang). There was no statistically significant difference of stress according to the constitution of stroke patients among three phases. Hence. stress was not influenced by the constitution of stroke patients, but there was a statistically significant difference of stress over time. 3. The pattern of stress of stroke patients classified by the paralyzed area across three phases ; Right paralyzed stroke patients perceived higher stress than left paralyzed stroke patients. There was, however, no statistically significant difference of stress between two groups except 2nd phase. There was no statistically significant difference of the perception of stress bet ween the right and left paralyzed stroke patients. 4. The pattern of stress of stroke patients classified by the frequency of the relapse of the disease across three phases ; Stress was higher in stroke patients who had the relapse of the disease twice more than the first time. There was, however, no statistically significant difference of stress between two groups. There was no statistically significant difference of stress of stroke patients according to the relapse of the disease among three phases. Hence, stress was no influenced by the relapse of the disease. 5. The relationship between the stress and self-care activities ; There was a negative relationship between the stress and self-care activities each phase(on admission, r= -.1563 ; before leaving the hospital, r= -.4030 ; after leaving the hospital, r= -.5291). Hence, the higher the self-care activities, the lower the stress. This study has three important findings. First finding was that psychological stress perceived by stroke patients was the highest among three phases. The second finding was that factors such as the constitution, the paralyzed area, and the relapse of the disease did not have an influence on the stress perceived by stroke patients across three phases(on admission, before leaving the hospital, after leaving the hospital). There was a statistically significant decrease of the stress perceived by stroke patients across three phases. The third finding was that there was a negative relationship between the self-care ability and stress. In this study, these findings have implications for nursing care for the rehabilitation of stroke patients and suggest the need of nursing intervention to promote the self-care ability and to support the psychological self-esteem of stroke patients.

This study was conducted to evaluate the effects of an abdominal obesity management program on dietary intake, stress index, and waist to hip ratio (WHR) in abdominally obese women. The subjects were 195 adult abdominally obese women (WHR ${\geq}$ 0.80) who had been participating in a nutrition education (total of nine times) and dietary habits and life style modification programs (total of six times) for 12 weeks. The abdominal obesity management program focused on the nutrition provided by breakfast, lunch, and dinner, proper dietary habits, and practices to improve life style. The subjects were divided into a WHR decrease group and a WHR increase group according to changes in the WHR. Daily nutrient intake was assessed with a 3-day food record, body measurements and blood vessel age, stress index, and a health index that were measured at baseline and after 12 weeks. After the intervention, weight, waist circumference, hip circumference, WHR, and body mass index (BMI) decreased significantly in the WHR decrease group. Energy intake increased from 1486.2 kcal to 1541.4 kcal with a significant improvement in nutrient density for animal protein, total fat, animal fat, fiber, calcium, phosphorus, zinc, vitamin $B_6$, vitamin C, vitamin E, and saturated fatty acids in the WHR decrease group. Additionally, dietary diversity increased significantly in the WHR decrease group compared to that in the WHR increase group. The WHR decrease group showed a significant improvement in the stress and health indices. Changes in WHR were correlated with changes in nutrient intake (animal protein, total fat, animal fat, plant fat, fiber, calcium, iron, potassium, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, and folate) and medical index profiles (stress and indices) adjusted for age, birth status, baseline BMI, and baseline WHR. These results show that an abdominal obesity management program was effective not only for reducing the WHR but also to improve dietary intake and the stress index in abdominally obese women.

This study aims at providing basic data to objectively evaluate the areas suitable for reintroduction of the species of Asiatic black bear (Ursus thibetanus) in order to effectively preserve the Asiatic black bears in the Korean protection areas including national parks, and for the species restoration success. To this end, this study predicted the potential habitats in East Asia, Southeast Asia and India, where there are the records of Asiatic black bears' appearances using the Maxent model and environmental variables related with climate, topography, road and land use. In addition, this study evaluated the effects of the relevant climate and environmental variables. This study also analyzed inhabitation range area suitable for Asiatic black and geographic change according to future climate change. As for the judgment accuracy of the Maxent model widely utilized for habitat distribution research of wildlife for preservation, AUC value was calculated as 0.893 (sd=0.121). This was useful in predicting Asiatic black bears' potential habitat and evaluate the habitat change characteristics according to future climate change. Compare to the distribution map of Asiatic black bears evaluated by IUCN, Habitat suitability by the Maxent model were regionally diverse in extant areas and low in the extinct areas from IUCN map. This can be the result reflecting the regional difference in the environmental conditions where Asiatic black bears inhabit. As for the environment affecting the potential habitat distribution of Asiatic black bears, inhabitation rate was the highest, according to land coverage type, compared to climate, topography and artificial factors like distance from road. Especially, the area of deciduous broadleaf forest was predicted to be preferred, in comparison with other land coverage types. Annual mean precipitation and the precipitation during the driest period were projected to affect more than temperature's annual range, and the inhabitation possibility was higher, as distance was farther from road. The reason is that Asiatic black bears are conjectured to prefer more stable area without human's intervention, as well as prey resource. The inhabitation range was predicted to be expanded gradually to the southern part of India, China's southeast coast and adjacent inland area, and Vietnam, Laos and Malaysia in the eastern coastal areas of Southeast Asia. The following areas are forecast to be the core areas, where Asiatic black bears can inhabit in the Asian region: Jeonnam, Jeonbuk and Gangwon areas in South Korea, Kyushu, Chugoku, Shikoku, Chubu, Kanto and Tohoku's border area in Japan, and Jiangxi, Zhejiang and Fujian border area in China. This study is expected to be used as basic data for the preservation and efficient management of Asiatic black bear's habitat, artificially introduced individual bear's release area selection, and the management of collision zones with humans.

The study attempts to examine the degree of cognition and demand on health promotion center of oriental nursing. It puts unique nursing intervention using traditional health promotion connected with oriental medicine to practical use for residents' health promotion and prevention of disease. With the study design of cross-sectional descriptive study, 516 residents who live in 26 Dongs, Dongdaemoon-gu were selected. The tool of study consists of 30 questions which the study team made for the degree of cognition and demand on health promotion center of oriental nursing. Cronbach's $\alpha$ in the degree of cognition was .8028. Collection of research data had been done from October 1 to October 30, 1999 with help of Dongdaemoon-gu office after pretest from 20 residents. Collected data were analyzed into the number and percentage in the characteristic of a subject and connected with demand on the establishment of center, the mean and the standard deviation in the degree of cognition and F-tests in the difference of the degree of cognition by characteristics. The results were as follow; 1) The characteristic of subject of this study was male 50.6%, and average age was 38.5 years old and 30-39 years old occupied the highest percentage with 31.6%. The married were 71.8%, over high school graduates was 85.6%, monthly income from 500 thousand won to 2 million won was 86.1%. 50.8% was the type living with parents, children and sibling. 2) When they were sick, the institution which residents used at first was a pharmacy(69.2%) and hospital(27.5%), but oriental medicine hospital was just 1.4%. As for subjective health condition, 82.5% answered over average, and 28.7% answered that they had chronic illness such as arthritis, chronic digestion problem, hypertension and so on. As for information collection on health, mass communication(34.9%) and medically concerned people(28.1%) occupied relatively high rate. Free health diagnosis system(36.8%) and establishment of health promotion center(31.5%) among welfare programs that residents want to enjoy were high ranked. The rate using a special institution for health was 17.8%, and among these institutions, the rate using aerobic exercises, health center(7.0%) and steamed room(5.4%) was high. Besides, other institutions such as breathing at the abdomen, finger-pressure therapy, meridian massage, foot massage, and so on were being used. 3) As the average of the degree of cognition on health promotion center of oriental medicine was 2.92, the degree of cognition was medium. The description, "health promotion center of oriental medicine is necessary for health keeping of healthy people, including people who have a problem in health" showed the highest degree of cognition(3.04, ${\pm}0.64$). 4) As for the intention on using health promotion center of oriental nursing, 61.4% said "yes", "no" was just 1.4%. The services that people relatively high wanted to be served from the center were measures reducing stress(68.0%) (relaxation therapy, meditation, breathing at the abdomen and so on), acupuncture(66.5%), finger-pressure(61.6%), moxibustion(57.6%), meridian massage(44.2%), postpartum care(40.3%) and so on. 5) As for the degree of cognition on the establishment of health promotion center of oriental nursing by characteristics of subject, there was significant difference(F=4.03, p=.046) between male(3.01) and female(2.91). But there was no significant difference by age, marital status, level of educational achievement and monthly income. As the above result, cognition on the establishment of health promotion center of oriental nursing was relatively low because people were not familiar with about the health promotion center of oriental nursing yet. However once the center will be established, the degree of demand on the center will be relatively high. So positive advertisement will be necessary, and the management of useful programs will be also required in order to make people recognize the advantage when they actually will use the center. On the other hand, as the subject of the study consists of many young people of below 30, the health problem came to be low. And in the case of sampling, the study using random sampling that can represent population will be required.

This study has attempted to determine the micro-discourse from blogs as personal media that reflect citizens' actual opinions of the Seoul Forest without intervention of experts. Furthermore, a qualitative research method discourse analysis was selected to analyze the micro-discourse regarding the Seoul Forest in a time series. The extracted samples of blogs by year were intended to identify the comment section of the process of change and the discursive structure. The results are as follows; first, from the beginning of the development of the Seoul Forest to the present, it is divided into four chronological periods along with individuals' micro-discourse with social changes. During the beginning of the development of the Seoul Forest, the social discourse was formed, and in the next period, the micro-discourse was developed with a more emotional and complex discourse. In the formative period, four or five years later, the discourse reflected the civic consciousness of development more than ever, showing the diversity of participation in the program at the Seoul Forest. In the growth period, as the users' experiences had been accumulated, the users started writing about the role of the Seoul Forest in their own words. This can also be called place discourse. From the individuals' micro-discourse, this study shows the discourse structure of how individuals think about the Seoul Forest in each period. Unlike the experts, the micro-discourse contains specific daily interactions, experiences, and the stories of individuals who actually use the parks. It also shows how users reproduce and understand the space. In this respect, this is the most significant finding of this study. Based on this research, this study has demonstrated that the emotional description of a place that actually functions as a discourse about city parks, and confirms that blogs could be used as a space to form discourse and as a research tool to read the trends. In accordance with these results, this study has described not only the discourse of experts, but also how the discourse of individuals' comments can be an important part of the discourse of modern urban parks.

This research is a descriptive correlation research to examine the relationship among stress, coping behaviors, and perceived social support in school-age children. Students in third, fourth, and fifth grades at one elementary school in A metropolitan city were included for this research. A researcher of the study visited the elementary school and obtained appropriate approval to conduct this survey. Then, a total of 481 students answered the questionnaire; finally, the questionnaires of 409 students were analyzed after excluding 72 questionnaires due to unreliable responses. Descriptive statistics, T-test, ANOVA, and Pearson's correlation were used to analyze the collected data with SPSS 13.0. In the stress scores, academic stress was associated with the highest score ($9.30{\pm}4.41$). With respect to stress coping behaviors, lower-grade students showed to have significantly higher scores in coping behavior of pursuing social support than higher-grade students (F=3.181, p=.043); male students had higher scores in aggressive coping behavior than female students (t=-3.399, p=.001). Perceived social support scores were higher in the following order: family members ($33.01{\pm}7.61$), friends ($28.43{\pm}7.89$), and teachers ($25.71{\pm}6.30$). Female students had higher scores in perceived social support from friends (t=3.842, p=.000) and teachers (t=3.037, p=.003) than the male students. As the stress scores increased, passive coping behaviors (r=.410, p=.000) and aggressive coping behaviors (r=.445, p=.000) have been significantly increased. As perceived social support is higher, active coping behaviors (r=.455, p=.000) and coping behaviors to pursue social support (r=.429, p=.000) were significantly increased. Therefore, we can conclude that stress management is very significant for children. It would be necessary to develop nursing intervention programs in order to reduce the aggressive and passive coping behaviors of children and encourage perceived social support.

Purpose: This paper aims to examine the subjective structures and types of school age children's perception of death through an investigative study on their perception of death in order to provide a basic material for them to understand death, and develop and carry out an effective death education program. Methods: The study method used the Q Methodology which can investigate the subjective structures and types of school age children's perception of death. For Q-population, 20 school age children were used as subjects for neutral interviews and open surveys, and through documentary research, a total of 132 statements were collected, For Q-samples, 23 statements (Q-samples) were derived through a non-structural method. P-samples were 31 school age children (8-13 year olds), Q-sorting was carried out using Q-cards, and the collected data was analyzed using the PC QUANL program. Results: As a result of the study, children's perception of death was divided into five types. The first type was functional type, characterized by prominent subjective perception regarding the elements of death, such as non-reversibility, universality, non-functionality, and causality. The second was after-life type, characterized by a strong, focus on life after death in one's perception of death, and it included children with Christian background and those who had experienced death in their immediate family. The third was religious type, characterized by a strong belief in being able to still watch over one's family and friends after one's death, resulting in a positive faith in the after-life. The fourth was fearful type, characterized by a deeper fear of death in comparison to other types. The fifth was realistic type, characterized by a strong and positive assent to the perception of good death. Conclusion: The significance of the results of this paper's study to Nursing is as follows. In terms of understanding the subjectivity of school age children's perception of death in nursing practice, and understanding the compositional elements of death presented with strong emphasis in existing literature and studies, the results will expand these understandings and allow us to understand the level of perception in school age children regarding the definition of death, after-life, and good death, be utilized as useful material in developing an effective death education program for them according to their type characteristics, and become the fertilizer for enabling the children to live a proper life and preventing the tendency to make light of death that occur in adolescence and the spread of suicides. In terms of nursing theory, the description and examination of the subjective structures and the characteristics of the different, types of school age children's perception of death can be utilized as useful material for building a model of school age children's perception of death, and be further used for teaching respect for life. In terms of nursing research, the results can contribute to research describing the effects of nursing intervention strategies and developing tools for providing psychosocial nursing in terms of giving school age children a positive perception of death according to their types as well respect for life.

An area's topography refers to the shape of the earth's surface, described by its elevation, slope, and aspect, among other features. The topographical conditions determine energy flowsthat move water and energy from higher to lower elevations, such as how much solar energy will be received and how much wind or rain will affect it. Another common factor, the topographic wetness index (TWI), is a calculation in digital elevation models of the tendency to accumulate water per slope and unit area, and is one of the most widely referenced hydrologic topographic factors, which helps explain the location of forest vegetation. Analyses of topographical factors can be calculated using a geographic information system (GIS) program based on digital elevation model (DEM) data. Recently, a large number of free open source software (FOSS) GIS programs are available and developed for researchers, industries, and governments. FOSS GIS programs provide opportunitiesfor flexible algorithms customized forspecific user needs. The majority of biodiversity in island areas exists at about 20% higher elevations than in land ecosystems, playing an important role in ecological processes and therefore of high ecological value. However, island areas are vulnerable to disturbances and damage, such as through climate change, environmental pollution, development, and human intervention, and lacks systematic investigation due to geographical limitations (e.g. remoteness; difficulty to access). More than 4,000 of Korea's islands are within a few hours of its coast, and 88% are uninhabited, with 52% of them forested. The forest ecosystems of islands have fewer encounters with human interaction than on land, and therefore most of the topographical conditions are formed naturally and affected more directly by weather conditions or the environment. Therefore, the analysis of forest topography in island areas can be done more precisely than on its land counterparts, and therefore has become a major focus of attention in Korea. This study is focused on calculating the performance of different topographical factors using FOSS GIS programs. The test area is the island forests in Korea's south and the DEM of the target area was processed with GRASS GIS and SAGA GIS. The final slopes and TWI maps were produced as comparisons of the differences between topographic factor calculations of each respective FOSS GIS program. Finally, the merits of each FOSS GIS program used to calculate the topographic factors is discussed.

This study examined the effects of balance taping therapy on improving knee pain and the obstacles to daily activity in rural elderly women. The research design was a quasi-experimental research using a non-equivalent control group pre-test and post-test design. The data were collected from January 19th to April 14th, 2017. The research subjects included female elderly over 65 years old who visited 12 senior centers located at Y city in rural areas. The participants were composed of 26 people in the experimental group and 28 people in the control group. Data were collected before and 24 hours after balance taping therapy, and the pain and obstacles to daily activity were measured. The collected data were analyzed using the PASW Statistics 23 Program, which included a $X^2-test$, Shapiro-Wilk test, and Mann-Whitney U test. After the intervention, significant differences were observed in the knee pain (Z=-6.658, p<.001) and obstacles to daily activity (Z=-3.466, p=.001). With regard to lower domain variables of the obstacles to daily activity, significant differences in standing up (Z=-2.860, p=.004), daily activity (Z=-2.629, p=.009), walking (Z=-3.868, p<.001), and dressing up (Z=-2.049, p=.040) were observed between the two groups. On the other hand, there were no significant differences in grip (Z=-.542, p=.588) and arm stretching (Z=-.416, p=.678). In conclusion, applying balance taping to rural elderly women clearly decreases the level of knee pain, reduces the obstacles to daily activity, and improves their quality of life.
