Background and objective: Recent urban agriculture meets the needs of urban residents that safety and avoids using chemical pesticides. This study was conducted to identify various factors of companion planting affecting the growth of cherry tomatoes, which will promoting urban agriculture by improving socioeconomic satisfaction with gardening activities through quality. Methods: Four types of companion plants such as marigold, zinnia, spearmint and basil, that have a companion effect with growth, sugar content, and vitamin C content. We obtained the mean and standard deviation and tested the significance at a 95% confidence level (p < .05) with Duncan's multiple range test after one way ANOVA and MANOVA. Results: Compared to monoculture of cherry tomatoes, the plant growth in the treatment plots with companion planting showed a significant increase overall(p < .05), but there wasn't interaction effect among companion plants, planting ratio and type. As for the absorption of inorganic components, the companion planting showed better absorption than monoculture of cherry tomatoes, as favorable growth, and there was an interaction effect among the individual factors. The sugar content was higher than the standard sugar content of 5.8 brix in both the treatment plots at the control, and vitamin C content was higher than the control at 26.27mg/100g in all treatment plots, but there wasn't statistically significant difference. The soil pH in the cultivation plot ranges from 5.5 to 9.0 and was weakly alkaline in all treatment plots except zinnia, showing low contents of phosphoric acid, exchageable potassium, calcium and magnesium. Conclusion: This study was conducted to analyze various factors such as the growth of cherry tomatoes, contents of inorganic components, sugar content and vitamin C content of fruits, and soil analysis according to companion plants, planting type, and planting ratio. We will study sugar content by measuring the change in growth every phase of fruits.

Disabled elderly faced with disability and the aged problems at the same time. So, this research creates two research questions and examines. First research question is how nine dimensions of daily life satisfaction according to gender difference. Second research question is how the factor of daily life satisfaction by gender difference. The data is sixty-five disabled elderly, 386 among Panel Survey of Employment for the Disabled(PSED, 2008). The methods of analysis for identifying research questions is t-test and multiple linear regression. The result of analysis on first research question, the gender difference six dimensions among nine dimensions of daily life satisfaction come out statistically significant. And The result of analysis on second research question, come out statistically significant, too. Socioeconomic status: the lower class, physical condition: bad health, chronic disease is or not, family and other people's social supports, disability: serious turn out to be factors in common. It has been suggested social policies from the results of studies that the provision of health support policy and program, enlarge assistance on daily life, support system on serious disabled elderly. On the other hand, analysis showed that distinctive factors between disabled elderly man and woman was age and education level. In other words, disabled elderly woman come out into the open that the more grow old, the less daily life satisfaction low, while disabled elderly man appeared higher daily life satisfaction in case of junior and senior high school graduate than uneducated.

This study sought to verify and examine the factors that influence social capital on social economy awareness. To summarize the results of the study, the results are as follows. As a result of analyzing the impact of social capital on social economy awareness, norms (t=3.228, p<.01) and participation (t=3.057, p<.01) had a significant impact on social economy awareness. In other words, the better the norms are observed and the higher the participation, the more influence it has on social economy awareness. Based on these results, the following implications were drawn. First, 'norms' refer to rules or standards that community members must adhere to within society, and these norms play a role in regulating the behavior of individuals and promoting social cooperation. Through this, it is believed that a strong normative system can have a significant impact on the way people participate or cooperate in social economy activities. Second, 'participation' is an indicator of how actively an individual or group participates in social activities. People with high levels of participation through social capital will have a high level of understanding of social economy awareness and will be able to act effectively. These results show that in previous studies, the better the norms were observed and the more trust and networks were strengthened, the higher the awareness of social economy. In contrast, in this study, norms and trust were found to have an effect, but the network did not, showing a difference from the results of previous studies, so repeated research is expected to be necessary in the future. Considering the results above, strengthening and developing the elements of social capital such as norms and participation can have a positive impact on overall socioeconomic awareness and development.

Drought risk is expected to increase as the frequency, intensity, and duration of droughts increase due to climate change. Drought risk is related to not only hydro-meteorological factors, but also water supply and demand. Recently, along with climate change, socioeconomic factors have also been recognized to increase drought risk. Therefore, it is necessary to outlook the drought risk considering various conditions for coping with future extreme droughts in a timely manner. In addition, considering various drought scenarios help reduce the uncertainty in future drought outlook. In this study, drought scenarios considering climate change scenarios, population, and water demand were created to outlook drought risk for 160 administrative districts in Korea, then new levels of drought risk were assigned based on the results of drought risk outlook to suggest drought management measures. The results showed that the drought risk will increase in the future in 2020, 2025, and 2030, compared to past. Especially the drought risk is likely twice as high in 2030 under the baseline and high scenarios. Applying the drought outlook results from this study to the new methodology for setting the risk levels shows that most regions are in Response (V) in 2020 and 2030 for baseline and high scenarios.

The main purpose of this study is to examine the effect of the family instability on the elderly suicide and to examine the change over time. An analytical model of causal structure was set up with residence, family instability and socioeconomic level as explanation variables for this study. The cause of death statistics and micro-data from the vital statistics for 1995, 2000 and 2005 were used. Family instability was measured through divorce, and the rate of elderly(male and female) suicide as well as the suicide rate of the elderly and those in their 20-50's was used for this analysis to examine the effect of divorce. This study hypothesized about family instability and elderly suicide through a literature review. This paper presents maps of the suicide rate by using GIS, and then ANOVA and regression analysis are carried out to verify a difference in the elderly suicide rate affected by residence and divorce. Divorce rate appears in most areas with a high level centering around metropolises except the central inland area. The rate of elderly suicide which stayed in only specific regions with a high level has increased as time went by, and the graph leveled high in most regions except the southwestern coast. In addition, the elderly suicide rate was increased rapidly in rural areas for the most recent 10 years. This shows the seriousness of problems of the aged in rural areas. Through the periods of economic crisis, a sudden increase in divorce causes family instability, which increase the suicide rate increasing. Divorce affects the elderly suicide rate and the 20-50s' suicide rate in the same way, and the stronger effect goes to the elderly rather than those in their 20-50s'. Regarding elderly suicide, the divorce has a different effect by gender, affecting males more than females. With these facts, we can draw the conclusion that family instability has the most significant effect on elderly males' suicide.

This study aims to enhance the family-friendliness of the region by examining the relationship between family relations and the community environment, and objectively comparing the local environment surrounding the family. To this end, we reviewed the areas of socio-cultural and economic sectors that affect the family relationship satisfaction, and in particular, analyzed the trend of changes in regional index by utilizing the Korean Family Happiness Composite Index (KFHCI) developed as a community indicators. This index utilizes community indicators published in the National Statistical Portal's "e-Region indicators," and these variables are related to family relationship satisfaction. Therefore, this study compared the seven areas of the Family Happiness Composite Index (Population Family, Health Culture, Education, Income Consumption, Employment Labor, Housing Transportation, Environment and Social Integration) by region, and examined the trends for 10 years. According to the study, the average score of KFHCI's entire region was rising from 2008 to 2018. Overall, the community environment that affects family relationship satisfaction is also improving. The regions belonging to the upper level were Jeonnam, Gangwon, Chungnam, Jeonbuk, and Gyeongbuk. Areas belonging to the lower level are Seoul, Busan, Daegu, Incheon, and Gwangju. In almost sectors, the lower-level regions did not have sufficient physical infrastructure compared to population density and over-density, and improved little by little, but not enough to reflect the needs of local people and improve the quality of life. In the future, we should develop more regular and complementary indicators to develop customized policies for each region that can improve the quality of family relationships. It will also be necessary to study the impact of each index field when a socioeconomic crisis occurs due to social disasters, and try to change indicators

Objective : The aim of this study was to investigate the care burden and life quality in family caregivers of community-dwelling patients using home mechanical ventilator(HMV) in Yeognam region. Methods : Survey performed to family caregivers of the patients using HMV in Yeognam region, Korea. The questionnaire is composed with patient care and the burden on caring. Korean version of Short Form Zarit Burden Interview(K-ZBI-12) and 3-Level version of EuroQol-5 Dimension applying Korean weight(KEQ-5D-3L) were also investigated. Statistical significance was accepted for p<.05. Results : A total 98 out of 150 questionnaires were analyzed. The K-ZBI-12(33.08±10.34) had a correlation with KEQ-5D-3L(0.71±0.25) negatively(p=.038). Patients' age, duration of HMV, financial burden and professional caregivers' care time had correlations with K-ZBI-12 positively(p<.05). KEQ-5D-3L correlated duration of HMV negatively(p=.017). Invasive ventilator group had lower KEQ-5D-3L than the non-invasive ventilator group(p=.008). K-ZBI-12 was lower in more than one caregiver care of patients than in one(p=.001). Conclusion : This study revealed high care burden and low quality of life in family caregivers of the patients with HMV in Yeongnam region, Korea. Efforts are needed to continually identify the needs of patients and their families, and the socioeconomic support and medical services associated with HMV.

Objectives: This cross-sectional study aims to investigate the prevalence and factors relating to handwashing with soap among Korean adults. Methods: Study subjects consist of 755 adults who have been contacted in September 2013 via telephone surveys. The data collected has been analyzed using descriptive statistics, a chi-square test and a logistic regression analysis. A primary purpose is to understand the prevalence of handwashing with soap more than 8 times daily and for 30 seconds per wash among adults. Independent variables include socioeconomic levels, the participants' perception and knowledge of handwashing and their educational experiences relating to handwashing. Results: The overall percentile of people who wash their hands with soap 8 time per day for 30 seconds or more per wash was 16.0%, which is 121 people out of 755 study subjects. In univariate analysis, age, education levels, monthly average income, handwashing habits, perceptions relate to the importance of handwashing, self-assessment of handwashing, environment of public toilet, and the completion of handwashing education shows significant result. Significant differences also appear (p<0.05) in logistic regression analysis on binary variables. There is a strong correlation between daily frequency of handwashing and willingness to wash hands while outside. For example, people who wash their hands very often while outside are 2.24 times (95% C.I. 1.29-3.87) more likely to practice handwashing with soap 8 times per day for 30 seconds or more per wash than those people who only intermittently wash their hands while outside. Furthermore, people with general unwillingness to wash their hands while outside are 4.61 times (95% C.I. 1.22-3.28) less likely to practice handwashing with soap 8 times per day for 30 seconds or more per wash than those with general willingness. Conclusions: This study has been carried out to identify the decision factors in practicing handwashing with soap for Korean adults. In univariate analysis, age, education level, monthly average income, handwashing habits, handwashing self-assessment, public toilet environment, completion of handwashing education and so forth have been identified to be the decision factors. This study result shows that the overall level of cleanliness of public toilet perceives to be poor and it suggests that the environment of public toilet needs to be enhanced. As the handwashing habits and handwashing-self assessment have been identified to be the significant decision factors for handwashing, there search and approach in these factors need to be developed further.

It is generally agreed that the country's population will grow up to the level of 52 million by the year of 2000 and that due the active growth of industry, urbanization and road constructions, sizable portion of existing arable lands will be utilized for other purposes than agriculture in near future. From 1966 to 1977, it was estimated that, the average annual conversion of arable lands to other uses, was 12,909 ha. If this trend persists, it is predicted that from 1978 to 1991 when the 6th Five Years Economic Development Plan will terminate, approximately 181,000 ha of arable lands will be converted for other uses again. On the other hand, it is certain that the increased population (39 million in 1981, 45 million in 1991, 52 million in 2001) and the changes in food pattern along with the enhancement of living standards will bring about the phenomenal increase in demands for not only the staple food but also the livestock products such as meat, milk and eggs, vegetables and fruits. These future increased demands for various foods, naturally mean the increased needs for the expansion of arable lands at the same time. It is predicted that, if more activities than present scale are not taken for the expansion of arable lands, the national food self sufficiency level will drop from 79% in 1977 down to 62% in 1991. To meet the increased food demands in future, there are several ways and means. These will include the increased land use intensity, elevation of unit area yield levels, minimization of conversion of arable lands to other uses and expansion of arable lands through the reclamations of idle hillside lands and tidal lands. Among these, the expansion of arable lands through reclamations of idle hillside lands and tidal lands are more positive measures to cope with the increased production of foods in future. The reclamation of hillside lands demands more attention because it needs more advanced technologies in agronomical and engineering aspects, larger scale fundings and integrated socioeconomic considerations. In agromical aspects, the thechniques for early improvement of chemical and physical properties of soils, proper soil conservation measures and rational cropping systems are of particular importance. As to the financial supports to encourage the farmings in hillside land, much bold fund inputs are essential for the construction of roads, installation of irrigation and drainage facilities, soil conservation mechanisms, which will ensure the stabilized farming with reasonable incomes in the newly reclaimed lands.
