This study aimed to apply a methodological approach, 'social network analysis' to a case study for the understanding of relational structure among stakeholders related to green tourism development. By doing so, this study argued that it is important to identify stakeholder's network structure to help green tourism planners develop collaborative relationship among stakeholders. This study identified the stakeholders regarding a community-based festival development in the southern area of Korea, and investigated two types of networks among them: decision-making power relational and intimate network. Interviewer-administrated survey and in-depth interview were employed for data collection. The data was analyzed by SPSS (version 10.0) and Net-MinerII (version 2.5.0), and by constant comparison method. The result revealed that low different groups of the stakeholders were separated in the intimate networt and that the festival organizational body was not connected with other stakeholders in the decision-making power relational network. The existence of separated groups and weak relationship among the stakeholders appeared to relate to age-group differences, and different views on the festival between the stakeholders.

초고령화된 한국 농촌에서 다양한 교육 및 직업 배경을 가진 중장년층 귀농인구의 유입은 고령화 문제에 대한 대안의 하나로 부각되고 있다. 본 연구는 농가 고령화에 대한 귀농인구의 잠재적인 기여도 측면에서 귀농인구의 지역별 유입 유출 패턴을 분석하였다. 분석에는 로그선형모형과 총합레퍼런스코딩을 사용하였고, 분석자료는 통계청의 2013년 귀농 통계이다. 분석결과에 의하면, 귀농인의 절반 정도가 수도권에서 비수도권 지역으로 이주한 인구이고, 이들을 제외하면 귀농인의 대부분은 원 거주지가 있던 도 내에서 이동하고 있다. 귀농인의 귀농 전 대비 귀농 후 지역 내 오즈비(odds ratio)는 지역별로 차이가 있으며, 귀농인의 성별과 연령에 따라서도 지역별 유입 유출패턴이 다르다. 이는 귀농인 유입의 긍정적 효과를 높이기 위해서는 지자체별 차이를 반영한 특화된 정책이 필요하다는 것을 의미한다.

기존 스마트팜 기술은 수요자 중심이 아닌 대량 생산을 목적으로 시스템화 되어왔다. 이는 고령화에 따른 실질적 농촌 환경에 적용되기에는 경제적인 측면 등의 많은 문제점이 있다. 본 연구에서는 농촌 지역 인구의 고령화로 인한 적용성을 전제로 스마트팜 기술을 적용하고자 한다. 뜨거워지는 폭염으로 인해 일반적인 온실재배시설의 농작물들은 일소 피해와 시들어 말라가는 경우가 많았다. 피해를 최소화하기 위해서는 온습도 환경을 조절해주거나 차광막을 설치해주어야 한다. 하지만 현재 농촌의 작업자들 나이가 점점 증가하고 있고, 홀로 농사를 짓는 고령자가 대다수여서 많은 일을 혼자 감당하기에는 어려움이 많다. 그리고 신체가 연약한 사람들의 경우, 무거운 짐을 옮기다가 자칫 안전사고로 이어질 위험이 있다. 본 논문은 이러한 문제점들을 개선하고 예방하기 위해 기존의 스마트팜 온실 내부에 작업자를 추종하는 소형 스마트 차량을 적용한 '자동 운반 기능이 가능한 스마트팜' 기술을 제안한다. 기존의 스마트 온실 환경제어 기능을 수행하며, 고랑마다 레일을 설치하고 작업자를 추종하는 차량이 있는 스마트팜이며, 어플리케이션을 통해 직접 온실과 차량을 원격으로 수동 제어할 수 있다.

Objectives: This study was performed to understand pregnancy, delivery, and infant rearing knowledge and educational need of marriage immigrant women to be utilized as a basic data for developing a suitable educational program. Methods: The subject of the study was composed of one hundred twenty two married immigrant women who live in South Korea. The method used in determining the population was the convenience sampling method. The data were gathered by means of personal interviews using questionnaires. Results: The mean score of pregnancy and delivery knowledge was 3.35, educational need was 3.64 out of 5, and infant rearing knowledge was 3.16, educational need was 3.66 out of 5. The pregnancy and delivery knowledge of the subject showed significant differences based on their present residential location and presence of children and their educational need varies according to their country of origin. The infant rearing knowledge on the other hand, showed notable differences according to presence of children while homeland and existence of children were the two major factors that greatly influenced the significant variation for educational need. Conclusions: The score of pregnancy, delivery and infant educational need were higher than knowledge. The score of pregnancy, delivery, and infant rearing educational need garnered similar results. Thus it is suggested that further researches should be conducted for the development, application, and verification of pregnancy, delivery, and infant rearing education programs that consider knowledge and educational need of immigrant married women in South Korea.

Background: The aim of this study was to compare the fatty acid composition, antioxidant activity, and the content of two major phenolic acids, caffeic and rosmarinic acids, of 45 Perilla accessions collected from Russia. Methods and Results: A total of 45 accessions of the genus Perilla were used in this study. The antioxidant activities of these accessions were analyzed using a spectrophotometer, and their caffeic and rosmarinic acid contents were determined using a reversed-phase ultraperformance liquid chromatography (UPLC) system. The Perilla seed oil was recovered using hexane in a soxhlet extraction method. The fatty acid compositions were analyzed using a Shimadzu QP2010 gas chromatography-mass spectoroscopy system. The results showed that accessions IT226732 and IT274300 had the highest content of caffeic and rosmarinic acid, respectively. A cluster analysis based on antioxidant assay results and concentration of phenolic acids led to the categorization of Perilla accessions into three major groups. The accessions in Group I were characterized by higher caffeic and rosmarinic acid content and antioxidant activity, compared to the accessions in the other two groups (p < 0.05). The total oil content ranged between 28.39 and 46.89%. The compositions of oleic, linoleic, and linolenic acid ranged from 11.83 to 19.55%, 11.92 to 16.71%, and 59.19 to 67.28%, respectively. Conclusions: The results of this study indicated that accessions IT274300, IT226732, IT274293, IT235818, and IT235820 could be used as a source of functional materials.

We analyzed the potential for joint utilization of Visible Infrared Imaging Radiometer Suite (VIIRS) satellite imagery Normalized Difference Vegetation Index (NDVI) in crop assessment, considering the aging of MODerate resolution Imaging Spectroradiometer (MODIS) satellites. Over 11 years from 2012 to 2022, we examined the characteristics of NDVI changes in corn and soybean cultivation areas in Illinois, USA. VIIRS and MODIS satellite imagery NDVI exhibited a high correlation coefficient of over 0.98. However, during periods of rapid crop growth or decline, VIIRS NDVI showed values approximately 0.12 to 0.14 higher than MODIS. Estimating crop anomaly classes based on NDVI, we observed similar trends in corn and soybean crop anomaly classes in 2018 and 2019. However, in 2022, there appeared to be a significant divergence in crop anomaly classes, suggesting the need for further investigation. The correlation coefficients between MODIS and VIIRS satellite imagery NDVI and corn and soybean yields were consistently high, exceeding 0.8, indicating the potential for quantity estimation using both MODIS and VIIRS satellite imagery. Specifically, for VIIRS NDVI, excluding the increasing trend in crop quantity estimation for soybeans enhanced the correlation, and compared to MODIS, it showed a consistently high correlation with quantity from approximately 16 days earlier, indicating the potential for early estimation.

In order to clearly define and understand an essential meaning on a growing number of immigrant women with an experience of being in pregnancy and childbirth, who married to men living in rural community in Korea, our study has been carried out with a phenomenological research method. Basic information collection was implemented by doing multiple in-depth interviews in being recorded with nine immigrant women married to the men, and also analyzed by the phenomenological method of Colaizzi. As the result of the study, the switchover in their life on the course to adaptation or transition to Korean life with experience of being pregnant and delivery generally classified into up to four categories and nine subjects. The four categories come out with "expectation of unknown world/country", "being experienced of new challenge", "feeling happiness going through anguish of hear" and "expectation/hope with her giving birth to a baby-transition in her life". Thus, the result of this study is intended to understand their difficulties likely caused or felt in adaptation to Korea life and culture, and to provide solutions or information of a program for their being actively adapted that may help get them easily assimilated into Korean life and culture.

Purpose: The purpose of this study is to compare the clinical features and complications of snake bite patients in urban and rural areas. Methods: A retrospective study was conducted on patients over 18 years of age who were hospitalized for snake bites from January 2013 to December 2019. Patients were categorized into urban and rural groups according to their respective locations at the time of the snake bite and the clinical characteristics and complications of the two patient groups were researched and compared. Results: Of the 77 snake bite patients, 44 patients were categorized into the rural group (57.1%). The rura1 group showed significant differences in old age (p=0.011), delayed hospital visits (p=0.010), far hospital distance (p<0.001), high local effect score (p<0.001), high traditional snake-bite severity grading scale (p=0.008) and use of large amounts of antivenins (p=0.026). There was a significantly higher incidence of acute kidney injury (p=0.030), rhabdomyolysis (p=0.026), and coagulopathy (p=0.033) in the rural group as well as a longer hospitalization period (p<0.011). Conclusion: Snake bites that occurred in rural areas resulted in patients with more complications compared to urban areas due to farther distances from hospitals, causing a delay in antivenom treatment.
