가뭄은 가장 심각한 기상 재해 중 하나로 농업 생산, 사회경제 등 다양한 분야에 영향을 미친다. 국내의 경우 광주·전남지역이 1990년대 이후 30년 만에 제한 급수 위기에 처하는 역대 최악의 가뭄으로 지역민들은 심각한 피해가 발생하였다. 유럽의 경우 2022년 당시 500년 만에 찾아온 가뭄으로 인해 3분의 2에 해당하는 지역이 피해를 입었으며, 미국 서부 지역은 2000년부터 2021년까지 1200년 만에 가장 극심한 대가뭄을 겪은 것으로 나타났다. 지구온난화에 따른 기후변화로 인해 가뭄의 빈도와 강도가 증가함에 따라 피해도 커질 것으로 예상된다. 가뭄의 부정적인 영향으로 인해 정확하고 신뢰할 수 있는 가뭄 예측 기술이 필요하다. 본 연구에서는 가뭄예측을 위한 입력변수로서 GPM IMERG (The Integrated Multi-satellitE Retrievals for GPM) 강수량 자료와 NOAA에서 제공하는 8가지 북반구 대기패턴 자료 간의 상관성을 분석하였다. 입력변수 간의 상관성과 중장기 가뭄 예측을 위하여 딥러닝 모델 중 시계열 데이터에서 높은 예측 성능을 보이는 LSTM(Long Short Term-Memory)을 적용하여 가뭄을 예측하고자 한다.

This study was carried out to understand the stand structure based on the compositional characteristics of natural deciduous forest dominated by Quercus species, which will provide with fundamental ecological and silvicultural information for effective forest management. Of two tracts selected from the Seoul National University Research Forests, one is located in Kwangju-Gun Kyunggi-Do, and the other in Kwangyang-Gun Chollanam-Do. Point-quarter sampling method w-as employed to survey woody vegetation confined to larger than 6cm in DBH. The numbers of sample points were 152 and 187, in Kwangju-Gun and Kwangyang-Gun, respectively. Comparative analysis for two forest tracts was made as follows ; 1) species composition by calculation of importance values ; 2) number of stems per hectare for major tree species ; 3) species diversity for the forests in two locations ; 4) inter-species association based on $X^2$ test. The relative dominate of Quercus speices showed 88% at Kwangju-Gun, Kyunggi-Do and 50% at Kwangy-ang-Gun. Chollanam-Do. Such high dominance occurred due to high importance values of Quercus variahilis and Q. mortgolica in both locations. Quercus serrata showed low value at Kwangju-Gun. Kyunggi-Do whereas Q. acutissirna, Q. dentata and Q. aliena did none at Kwangyang-Gun. Chollanam-Do. The species diversity and evenness in oak communities exhibited 0.82 and 0.61, respectively at Kwangju-Gun. Kyunggi-Do, while those did 1.09 and 0.73 at Kwangyang-Gun, Chollanam-Do. Therefore, it was considered that Ku-angju-Gun region was disturbed severely by human activities but Kwangyang-Gun region eras less disturbed. Frequent appearance of Carpinus and Acer species indicates increase in diversities and better development of succession at Kwangyang-Gun region.

Objectives: This study investigated the relevance of dietary behavior and oral management for oral heath in adults to extend the recognition of the importance of food intake in oral health and to provide basic information for oral health management. Methods: A survey and clinical assessment were conducted for 119 adults over 20 years of age. The chi-square test and logistic regression analysis were carried out using SPSS Statistics 20.0. Results: Gingivitis was influenced less when ham and sausage in the sub-area of meat, fish, egg, and bean were consumed once a week rather than the cases when consumed rarely (3.47 times) or when consumed two times or more a week (7.87 times) (p<0.05). Periodontitis was influenced more in the groups of 30s and 40s age than in that of over 50 years of age (14.97 times, 7.73 times) and in the group without drinking experience than in group with that (4.17 times) (p<0.05). Conclusions: The results verified the close relationship between food intake frequency and oral health in patients with periodontitis and gingivitis. Thus, it would be necessary to study the relationship between dietary behavior and oral health continuously.

Objectives: This study aimed to investigate the changes in the eating habits and lifestyle of middle-aged women in Gwangju during the COVID-19 pandemic. Methods: A total of 428 middle-aged women aged between 40 and 60 participated in a survey relating to general information, food and lifestyle, health functional food, and menopausal symptoms. The correlation between the variables was analyzed. Results: In the positive habits, the intake of nutritional supplements for immunity enhancement increased the most, followed by the use of media to learn healthy eating tips, and diets including healthy food. Negative habits increased in the order of frequency of taking delivery orders, levels of stress or anxiety, and time spent sitting or watching movies. In the case of recommended foods, the intake increased the most in the order of eggs, fruits, vegetables, milk/dairy products, and seaweed. Non-recommended foods increased in the order of meat, bread, rice, and noodles. The awareness of health functional foods was in the increasing order of interest, knowledge, consumption experience, and purchase amount. The type of health functional food intake was in the increasing order of probiotics, multivitamin and mineral supplements, vitamin C, collagen, and omega-3. Menopausal symptoms were in the increasing order of bone and joint pain, poor sleep quality, emotional ups and downs, loneliness, and feeling of emptiness. In the correlation of major variables, positive habits showed a significant positive correlation with recommended food intake and the recognition of health functional foods. Negative habits showed a significant positive correlation with non-recommended food intake and a significant positive correlation with menopausal symptoms. Recommended food intake showed a significant positive correlation with health functional food recognition and intake and menopausal symptoms. Conclusions: This study suggests that it is necessary to establish social measures to reduce the negative effects of the COVID-19 pandemic on middle-aged women and to ensure effective self-management through a healthy lifestyle since the pandemic has a long-term impact.

Objectives: This paper aimed to provide an in-depth analysis of the factors influencing the dietary habits of male and female workers at a facility in Gwangju and their awareness of the same. Methods: A total of 32 workers were divided into eight groups based on work type, gender, and age, and focus group interviews (FGIs) were conducted. The FGIs included cognitive, behavioral, and environmental questionnaires based on dietary habits and the social cognitive theory. The interviews were analyzed by subject and sub-subject using audio recordings and transcriptions. Results: Male workers in the concerned company favored meat while female workers preferred vegetables, yet by and large, the preferences were irregular. Male workers living alone frequently ate ready meals and female workers often skipped meals. An analysis of the factors influencing the study subjects' dietary habits from the cognitive, behavioral, and environmental perspectives showed that the main factors negatively affecting their dietary habits were shiftwork, living alone, and drinking. Workers were unaware of these factors and their poor eating habits. Instead, male workers complained of poor cooking skills, while female workers complained of loneliness. Workers thus appeared to need the support of nutrition education and a counseling assistant to cope with this situation. Conclusions: The study identified the fact that the absence of nutrition education left the workers unaware of their poor eating habits. The workers would need counseling and support to help them build healthy dietary habits. It would also be necessary to focus on raising the workers' cognitive awareness of dietary habits and enhancing their behavioral ability to cope with bad eating habits through nutrition education that reflects the reality of their situation.

Regional communities have recently tried to change themselves in order to cope with rapidly changing circumstances. Giving attention to their strategic responses as well as consequences as a result of their countermeasures, this study attempts to suggest a theoretical framework to analyze the process of locality reconstruction in a dynamic and comprehensive way. To achieve this purpose, after figuring out the previous studies' methodological and theoretical limitations, we suggest that locality should be understood as a outcome of the mutual interactions between local, state, and global scale networks.

The dual purposes of this study were to investigate footwear worn by college students who have become spoilt for choice in apparel & shoes, and point out the problems of their shoe-wearing habbits. The survey was administered in October, 2010 to 600 college residents in Kwangju-Jeonnam area and the results are as follows. Firstly, the most frequently worn footware by males were sneakers, followed by dress shoes and oxford shoes. Females followed a similar trend with sneakers being the most frequently worn, followed by high heeled shoes, flat shoes, wedge high heeled shoes and chucker boots. Secondly, both male and female students thought that the most comfortable and favorable shoes for them were sneakers and the most uncomfortable ones were high-heeled shoes and sandals. They thought chucker boots were both fashionable and comfortable. Thirdly, the degree of unsatisfaction for shoes was relatively high and the influencing factors for unsatisfaction were uncomfortable soles, aches around the toes and a frontward leaning posture of the body, etc. Finally, 87% of the female subjects who had experience wearing high-heeled(over 7cm height) shoes showed a significant increase in foot disorders than those who had never worn high-heeled shoes. According to the results, it is necessary to educate proper selection and wearing of footwear in order to prevent foot disorders and maintain overall health of the body.
