This study examined the effective uses of an ecosystem service value assessment in the fields of rural planning and development through archiving and reviewing/analyzing existing concepts, evaluation methods and prior examples of Ecosystem services. Based on land cover analysis, this study evaluated the usability changes in the ecosystem service value for a period spanning 1975 to 2000. The results from the countrywide data survey (with an exception of Jeju island) showed a 33.15% decrease in ESV by 2000. The total ESV represented 5,385 million USD in 1975, and 3,600 million USD in 2000 of the study area. In addition, the ecosystem service value with a scale of metro cities and provinces was also examined. The ESV of most regions decreased by 2000, but Daejeon and Kyeongnam, and Kyeongbuk provinces increased. The trends of year to year changes in the ESV were very diverse throughout the country. Jeonnam showed the smallest decrease, 747 million USD, which is 59% of the ESV in 1975. Nevertheless, the despite the regional differences in available natural resources, the natural resource assets value is ultimately determined by rural development policies and regional economic attributes. Therefore, an ecosystem service must be considered as an important criterion for rural planning and development policy.

Balloon flower (Platycodon grandiflorum) is a kind of mountain herbs whose roots have restorative properties and the cultivating acreage of balloon flower has been steadily increasing in Korea. More frequent rain and high amount of rainfalls as a result of climate changes predisposed balloon flower to the outbreaks of root rot at high-density cultivation area in recent years. Root crowns were usually discolored into brown to blackish brown at first and the infected plants showed slight wilting symptom at early infection stage. Severely infected roots were entirely rotted and whole plants eventually died at late infection stage. The overall disease severities of root rot of balloon flower were quite variable according to the surveyed fields in Jeonnam, Gyeongnam and Jeju Provinces, which ranged from 0.1% to 40%. The root rot occurred more severely at the paddy or clay soils than the sandy soils and their severities were much higher at lowland than upland in the same localty. The disease increased with aging of the balloon flower. The causal fungi were identified as Fusarium solani and F. oxysporum on the basis of their mycological characteristics. The optimum temperature ranges of their mycelial growths was found to be $24^{\circ}C$. The pathogenic characters of F. solani and F. oxysporum treated by artificial wounding inoculation on healthy roots of balloon flower revealed that F. solani was more virulent than F. oxysporum. This study identified the causal agents of root rot of balloon flower as Fusarium solani and F. oxysporum, probably for the first time.

Korean traditional house has inherented construction characteristics that contain human requirements with the adaptation to nature's order. As for traditional buildings, there are a lot of facilities like palaces, Buddhist temples, Confucianism architectures, government facilities, etc. Among them, housing construction is not only closely connected to our lives, but also plays an important role to connect our lives from the past to present. The master room in a traditional korean house is responsible for playing a center role of the residential life which implies the traditional values responsible for multi-functions and it is also the sphere of the living space. Therefore, this thesis considers the residential environmental adjustment method and the behaviors centered around the main buildings of Jeonnam Province. And also investigates the main reason for windows and doors formation. From this, we would like to further evaluate the master room life, and the inner space constructions following the spacial and organizational analysis of windows and doors. We would like to analyze the space organization methods, environmental adjustment methods and the usages of traditional buildings. Using the modern interpretation as basis, we would like to use the foundation materials to reflect single family housing plans.

The purpose of this study is to examine the middle aged social preparation for later life and to explore the effect of social activities and social relationships on social preparation for later life. This research is also focused on gender differences in social activities, social relationships and social preparation for later life. The survey data was gathered from 424 middle aged citizens who live in the Gwangju & Jeonnam area, using a structured questionnaire. The statistical methods used for data analysis were descriptive statistics, cross tables, t-test, correlations, and hierarchical regression with SPSS win 18.0 program. The major findings of this study are as follows: Most of the respondents perceive an importance of social activities and social relationships. Middle aged women enjoy leisure activities such as learning and religious activity more than men. Middle aged men engage in hobby activities more than women. And most of respondents perceive they are making an effort to keep a relationship with spouses, family & friends. The results show that there are no differences in social preparation for later life between gender groups, but the variables which have an effect in social preparation for later life are different between gender groups. Social activities and Social relationships play an important role in social preparation for later life of Middle aged men and women. At the same time, Social activities and Social relationships have more positive effect on the social preparation of women. Implications of the results are discussed.

Purpose: The purpose of this study was to analyze the research papers published in three nursing journals to suggest the direction for Journal of Korean Oncology Nursing (JKON). Methods: To compare JKON with Journal of Korean Academic Society of Nursing Education and Cancer Nursing, all the research papers published in those three journals, 2010 were reviewed using an analysis criteria developed by the researchers, focusing on type of research, characteristics of authors and subjects, research design, data collection and analysis methods, sample size estimation, and ethical considerations regarding data collection. Results: JKON lacked research papers which were supported by research funds, produced by multidisciplinary teams, addressing cancer survivors or patients with metastatic cancers, and written in qualitative methodologies. However, JKON showed higher ratio of research papers than the other two journals which were adapted from thesis or dissertations, describing sample size estimation process precisely, and participating subjects diagnosed with various cancers. Conclusion: The study found out that JKON is presenting well the area of oncology nursing in Korea and also has several weak points that need to be improved. The study therefore suggested several recommendations for the JKON to take the professional and global leader roles.

Objectives: This study was performed to assay the effect of neodymium oxide on the generation of reactive oxygen species and DNA oxidative damage by intratracheal instillation. Methods: Two groups of rats were exposed to neodymium oxide($Nd_2O_3$) via intratracheal instillation with doses of 0.5 mg and 2.0 mg, respectively. At two days and at 12 weeks after exposure, the contents of neodymium oxide in the lung, liver, kidney, heart and brain, leukocyte, olive tail moment, ROS, RNS, lactate dehydrogenase, albumin, cytokine and MDA from BALF were measured. Results: Neodymium oxide contents in the liver, kidney, heart, and brain were detected at less than $1{\mu}g/g$ tissue concentration. However, in the lungs at four weeks the highest amount were detected and then found to be drastically reduced at 12 weeks. ROS and RNS in bronchoalveolar lavage increased in concentration dependently at two days, four weeks and 12 weeks after neodymium oxide instillation. However, ROS and RNS decreased with the passage of time. At two days the total number of WBC in BALF in the high concentration group was significantly increased, and at four weeks the total number of WBC were significantly increased in the low and high concentration groups(p<0.01). At two days after exposure, the LDH of the low and high concentration groups was significantly increased. At 12 weeks, only the LDH of the high concentration group was significantly increased compared to in the control group(p<0.01). As a result of Comet assay, after two days, damage to the DNA of the low and high concentration groups was observed. Conclusions: Intratracheal instillation of neodymium oxide induces the generation of ROS and DNA damage in rats.

Objectives: This study was performed to produce data on the pulmonary toxicity of neodymium oxide($Nd_2O_3$) by intratracheal instillation. Methods: Two groups of rats were exposed to neodymium oxide by intratracheal instillation with doses of 0.5 mg and 2.0 mg, respectively. At two days, four weeks and 12 weeks after exposure, body weight change, organ weight change and histopathological change were observed. At 12 weeks after exposure, lung function change was measured. Results: The body weight of rats in the high concentration group decreased after 12 weeks by 4-5% compared with the control group. At four weeks and 12 weeks after the administration of neodymium oxide, the absolute weight of the lungs of the high concentration group were significantly increased when compared with the control group(p<0.05). At 12 weeks after the injection of neodymium oxide, breath frequency and respiratory minute volume were increased, but inhalation time and expiratory time were decreased. Bronchiolar epithelial hyperplasia, alveolar type II cell hypertrophy/hyperplasia and foreign body granulomatous inflammation were observed in the high exposure group. Conclusions: Body weight decrease, lung absolute weight and breath frequency increase, and pathological lung change were all observed. We found that pulmonary toxicity of neodymium oxide nanoparticles by intratracheal instillation could be confirmed.

This study investigated and tested the overall level of dietary habits and health status/health management of the residents in a rural area. The interview survey was performed in March 2004 with a structured questionnaire to 510 residents who lived in Muan-Gun of Jeonnam province. The questionnaire was the abridged Scale of Dietary Habits and Health Status which surveys the morbidity, subjective health status, health management, and health examination. The Chi-squire method was used for some of the cross-sectional data. The 510 adult respondents were composed of 61.2% male and 38.3% female. In regularity of meal time, 56.3% of the subjects had a meal regularly(eating time), while 73.5% had a balanced diet(eating number). The habit of regular meal time was significantly higher in old people than in young people. The majority of the subjects had an appropriate meal amount. Unbalanced diet was higher in young people than in old people. 51.4% had the dining out and was significantly higher in younger people than in old people. In other questions, 60.7% of the subjects took a snack, 77.3% were under regular health management, and 49.6% had health examination. A minority of the respondents (31.3%) had disease, while 13.5% chronic disease, and 17.8% had acute disease. The level of dietary habits and general characteristics were positively correlated with each other, as were habits and health status. These results suggest the need for nutritional education programs directed at young people with a special emphasis on regularity of meal time. unbalanced diet, dining-out and a snack.
