Nara Jeong,Sanghui Kang,Deugsoo Ahn 전북대학교 휴양및경관계획연구소 2016 휴양및경관연구 (J East Asian Landscape Studies) Vol.10 No.4

The goal of this master plan is to revitalize the local economy and provide local citizens with a place for leisure activities by transforming the magnificent pine forestscape at Geumam neighborhood park into a tourism resource. The present study has analyzed and synthesized the natural and human environments of the target site, which is located in Noam-dong, Namwon-si, in Jeollabuk-do. This master plan has adopted a motto, “engage five senses in pine trees; entertain five senses for fine life”, to express its philosophy of how to utilize the resources of pine trees. To this end, the present study has specified the suggested contents based on literature review of the studies on pines. Beyond an ordinary theme park, this master plan has been designed to create a central space that connects many rural village forests located in Namwon. In this master plan, main facilities have been suggested: the pine exhibition/experience hall, where visitors can appreciate and experience various materials related to pines; and the pinewood cabin, which is built with huge pine trunks, providing multiple functions as a space for rest and recreation ; the healing forest, which utilizes the existing pine forest; the pine sculpture garden; and the pine poem garden. In addition, the present study suggests two representative tourism resources of Namwon as symbolic elements: the herbs and royal azaleas of Mt. Jiri. unique hands-on pine experience activities available at these spaces have been proposed in two categories: festival programs and year-round programs.

Nara Jeong,Seungwon Han,Kwangjin Kim,Youngbin Jung 전북대학교 휴양및경관계획연구소 2018 휴양및경관연구 (J East Asian Landscape Studies) Vol.12 No.4

The purpose of this study is to establish how community garden spaces should be used to restore communities engaged in village-rehabilitation projects. To achieve this purpose, we have analyzed the perceptions of local residents conducting a town-development project. The community reviewed the benefits of having a garden to improve the residents’ quality of life and comfort. Given the role of gardens in revitalizing communities, it is necessary to build spaces where residents can relax and enjoy community life. Those who participated in this study hoped that their community garden would provide shade and relaxation, a children’s play area, green spaces, and places for conversation. The space and facilities provided by community gardens vary, in accordance with the expectations and needs of each community. It is therefore inappropriate to apply uniform garden designs to all community gardens. Between 20% and 25% of a community garden should be allocated to each of the following: community space, ornamental space, and space for relaxation. As plants that provide shade and help to maintain the ecosystem are strongly preferred in community gardens, all plants should be chosen for their environmental benefits and functionality, rather than aesthetics. Residents may be willing to participate in a range of activities, including community events, the cultivation of plants, and garden management. Towns must therefore set up programs to support these activities. It is essential to continue studying and investigating the formation of community spaces and facilities, reflecting the characteristics of each community.

This study was analyzed the image and satisfaction degree of forests and their healing perception effect in both physical and emotional aspects according to the type of forest. The type of forests in this study included Chamaecyparis obtusa forest, Quercus serrata forest and Pinus densiflora forest, and the selection areas with a single forest physignomy were selected and evaluated. The evaluation was performed by 60 subjects at each forest. Chamaecyparis obtusa forest was evaluated to have a pleasant, comfortable and friendly image, Quercus serrata forest was estimated to have a plain but stable and open image, and Pinus densiflora forest was evaluated to have a beautiful, pleasant and natural image. The image structure of forest is classified into factors including orderliness, amenity, singularity and emotion. For the satisfaction level of forest, Quercus serrata forest showed the highest satisfaction level. The satisfaction level regarding the Chamaecyparis obtusa forest, Quercus serrata forest, and Pinus densiflora forest was influenced by orderliness, orderliness and singularity and amenity respectively. In all forests, the subject perceived the healing effect of improvement in physical and emotional aspects, and especially, the perception on the healing effect in an emotional aspect was high. The satisfaction level regarding the forest and the perception of the healing effect in an emotional aspect showed a positive relationship.

Comparative Analysis of the Long-term Management Plan of Natural Parks - A Focus on Jeollabuk-do Provincial Parks -

Nara Jeong,Sanghui Kang,Deugsoo Ahn 전북대학교 휴양및경관계획연구소 2018 휴양및경관연구 (J East Asian Landscape Studies) Vol.12 No.4

The purpose of the present study was to compare the long-term management objectives, policy objectives, implementation plans, and detailed plans of four provincial parks established in 2013 using various analysis frameworks. Through this, the study aimed to identify the characteristics of the management plan and extract the implementation plan important to each park by analyzing the priorities in the detailed plan. The long-term management objectives of most parks were to maintain recreational functions by utilizing all the resources of the park, rather than merely preserving the ecosystem. From an ecological perspective, information on major plants and legal protection species are included for most parks, and geological and topographic features considered a major resource. For sustainable forests, it is important to induce the dispersion of concentrated use space. Efficient management systems are distinctively differentiated among the parks. For regional revitalization, the management of programs to link provincial parks and their surrounding areas has become most important. From an ecological perspective, priorities differed for the parks according to their ecological characteristics. For sustainable forests, Moaksan Provincial Park prioritized the visitor reservation system related to the overall park, while the other three parks prioritized alleviating the concentrated use of specific areas. From an efficient management perspective, Daedunsan Provincial Park prioritized aspects related to the cableway. Maisan Provincial Park prioritized inducing the linkage between the use of natural and cultural resources, and Seonunsan Provincial Park prioritized establishing an ecological and cultural commentary operating system. For the base-type leisure activity space, Moaksan Provincial Park prioritized the systematic management and operation of the pilgrimage route, Maisan Provincial Park the connection between the Maisan geography and residents’ income, and Seonunsan Provincial Park providing a space for ecological education.

Release of Sr From Sr-Coprecipitated Calcite Under Various Environment Conditions

Nara Jeong,Wooyong Um 한국방사성폐기물학회 2022 한국방사성폐기물학회 학술논문요약집 Vol.20 No.2

Concrete is used as the main engineering barrier in low and intermediate level radioactive waste disposal facilities. As the time passed, the radionuclides stored in repository may contact with groundwater and leak into the ecosystem through the rock media. In this process, the radionuclides can react with calcite via sorption or coprecipitation, because calcite is the major mineral of concrete. Under the various background conditions in repository, frequent dissolution-precipitation reactions can happen. Dissolution of Sr-coprecipitated calcite may be different from that of SrCO3(s) which can mislead the safety performance of radioactive Sr and the estimate of Sr mobility based on the solubility of SrCO3(s). Strontium is not only one of the fission products but also emits beta rays with a long half-life almost 29 years. The strontium may be released or retarded by the dissolution-precipitation reactions in repository. In this study, the dissolution of Sr-coprecipitated with respect to calcite was tested in various environment conditions. The Sr-coprecipitated calcite, (Sr,Ca)CO3(s) was synthesized by coprecipitation method in alkaline condition. The 250 mL of 0.1 M of CaCl2 solution was mixed with 250 mL of 1.14 mM SrCl2·6H2O solution. Then, independently prepared 500 mL of 0.1 M Na2CO3 solution was mixed with the mixed solution of CaCl2 and SrCl2. The precipitates could be made and they were aged for 3 days at room temperature. Then, the supernatant was separated by the centrifugation and the solid at the bottom was dried in an oven at temperature 80°C. After that, the Srcoprecipitated calcite powder was washed using the DI water several times and dried again before use. Characterization of solid powder was conducted by XRD and SEM, and the ICP-MS and ICP-AES were used to analyze the concentrations of Ca and Sr. The batch dissolution experiment was conducted with a solid-to-solution ratio of 10 g/L groundwater in polyethylene tubes. The oxidative groundwater was synthesized by simulating the chemical composition of KAERI Underground Research Tunnel (KURT) DB-3 groundwater. Different temperatures and pHs were prepared and tested for the release of Sr and Ca from the coprecipitated (Sr,Ca)CO3(s) to compare the results with the release of Sr and Ca from SrCO3(s) and CaCO3(s), respectively. Such as, these results will be used to provide better understanding of Sr release and mobility in various repository environments.

Downregulation of PyHRG1, encoding a novel secretory protein in the red alga Pyropia yezoensis, enhances heat tolerance

Narae Han,Jiwoong Wi,Sungoh Im,Ka-Min Lim,Hun-Dong Lee,Won-Joong Jeong,Geun-Joong Kim,Chan Song Kim,Eun-Jeong Park,Mi Sook Hwang,최동욱 한국조류학회I 2021 ALGAE Vol.36 No.3

An increase in seawater temperature owing to global warming is expected to substantially limit the growth of marine algae, including Pyropia yezoensis, a commercially valuable red alga. To improve our knowledge of the genes involved in the acquisition of heat tolerance in P. yezoensis, transcriptomes sequences were obtained from both the wild-type SG104 P. yezoensis and heat-tolerant mutant Gy500. We selected 1,251 differentially expressed genes that were up- or downregulated in response to the heat stress condition and in the heat-tolerant mutant Gy500, based on fragment per million reads expression values. Among them, PyHRG1 was downregulated under heat stress in SG104 and expressed at a low level in Gy500. PyHRG1 encodes a secretory protein of 26.5 kDa. PyHRG1 shows no significant sequence homology with any known genes deposited in public databases to date. However, PyHRG1 homologs were found in other red algae, including other Pyropia species. When PyHRG1 was introduced into the single-cell green alga Chlamydomonas reinhardtii, transformed cells overexpressing PyHRG1 showed severely retarded growth. These results demonstrate that PyHRG1 encodes a novel red algae-specific protein and plays a role in heat tolerance in algae. The transcriptome sequences obtained in this study, which include PyHRG1, will facilitate future studies to understand the molecular mechanisms involved in heat tolerance in red algae.

Nara Jeong,Myeongil Jeong,Seungwon Han,Jaesoon Kim 전북대학교 부설 휴양및경관계획연구소 2015 휴양및경관연구 (J East Asian Landscape Studies) Vol.9 No.3

본 연구는 주택정원을 조성하는데 필요한 기초자료를 얻기 위하여 정원을 소유하고 있는 도시민과 소유하지 않은 도시민들의 정원 이용 행태와 선호에 대한 인식을 분석하고자 하였다. 전국 대도시의 농업기술센터에서 도시농업 및 정원 관련 교육이나 프로그램에 참여하는 도시민 508명을 대상으로 실시하였다. 실제 정원 소유 집단의 정원 규모는 넓지 않으며 무소유 집단 또한 소규모의 정원을 가꾸길 희망하고 있다. 정원을 이용하는 목적으로 두 집단 모두 휴식, 먹거리 재배, 마음 안정을 추구하고 있다. 하루 중 정원에서 소요하거나 소요하고 싶은 시간은 30분에서 2시간 정도로 분석되어 일상생활의 여가시간 중 정원 활동이 차지하는 비중이 적진 않다. 정원 소유 집단은 식물(나무)가꾸기, 텃밭가꾸기, 휴식 등의 이용행태를 보이며 무소유 집단 또한 이러한 행태를 희망하고 있다. 이는 이용 목적과 비슷한 경향으로 도시민들은 식물, 나무, 텃밭 등의 정원을 가꾸고 정원에서 휴식을 취하길 기대하고 있는 것으로 사료된다. 정원 조성 시 고려해야 할 사항으로 그늘 바람에 의한 쾌적함, 환경오염에 대한 완충이나 정신적 위안을 포함하는 건강함, 자연성, 아름다움을 중시하였다. 정원에서 식재공간, 휴게공간, 텃밭, 다목적공간 등을 선호하였다. 응답자들은 정원에 그늘을 제공, 계절별 꽃 감상, 열매를 제공할 수 있는 식물, 아름다움 형태 등의 식물 도입을 선호하였다. 정원 관리에 있어서 병해충 및 식물을 비롯한 체계적인 정원 관리방법이 문제가 될 수 있으므로 이를 위한 정원 관리 교육이 진행될 필요가 있다. 또한 정원 소유 집단은 병해충 방제, 식물 전정 및 정지, 식물 파종 및 식재 방법 등 실제적인 교육을 요구하였으며 무소유 집단은 정원 조성방법, 총괄적 관리방법 등에 관한 교육을 선호하여 수요자의 요구에 맞도록 정원 교육이 이루어져야 할 것이다. This study acquired basic data on the requirements for beginning home gardening by analyzing the level of awareness of gardening behaviors and preferences of both urbanites who do and not own gardens. The study participants were 508 urbanites who participate in urban farming, garden-related education, or programs at agricultural technology centers in major metropolitan areas in Korea. It was found that the gardens owned by the garden-owner group were not very large, and the non-owner group expressed a desire to own small-sized gardens. Both groups stated that their purposes for owning or wanting to own a garden included relaxation, growing food, and relaxation. The garden-owner group demonstrated usage behaviors associated with plant care, vegetable-garden care, and relaxation, while the non-owner group expressed their desire to use their gardens for the same purposes. The behaviors of both groups matched their stated purposes of garden usage. Aspects of gardening that were considered important included naturalness, aesthetics, amenity of being sheltered from the sun and wind, health benefits (such as being safeguarded from pollution), and emotional comfort. Gardens were preferred as spaces for planting, relaxing, vegetable growing, and multi-purpose uses. The respondents also favored plants that provide shade, seasonal flowers to admire, and fruit and plants that are aesthetically pleasing. Systematic management methods (including plant pest control) should be taught for garden management. Moreover, the garden-owner group required education regarding pest control, training and pruning, and planting methods, whereas the non-owner group preferred education on garden development and comprehensive care methods. Therefore, garden education must be imparted based on user needs.

Planning for Mother’s Garden of Memory in Seoul Garden Festival

Nara Jeong,Myeongil Jeong 전북대학교 휴양및경관계획연구소 2016 휴양및경관연구 (J East Asian Landscape Studies) Vol.10 No.2

A garden festival is characterized by its nature as a garden exhibition event. The Seoul Garden Festival was held to expand garden culture, increasing citizens’ quality of life, and also to achieve urban regeneration through discovery and development of features of various gardens in Seoul. Mother’s Garden of Memory is based on the motif of the gardens tended by mothers in the past, and inspires recollection of related memories and stories. Gardens tended by mothers in the past can be encountered today in everyday life as practical living gardens. Facilities and suitable space sizes for a living garden were selected based on previous research results. The exhibition garden was designed to include a fruit tree hill, medicinal plant/herb garden, and butterfly garden in its planting space; a vegetable garden in its multi-purpose space and production space; a pond in its waterscape space; and a seating wall in its resting space. Additionally, the garden’s plants consisted primarily of species that were suitable for the characteristics of each space, could be tended practically, and could be accessed easily. Finally, a garden management plan was established to provide a model for living gardens, ensuring that these gardens could be continuously sustained.

Analysis on the Residents’ Consciousness and Importance of Resources for Rural Development Direction

Nara Jeong,Soyoung Lee 전북대학교 휴양및경관계획연구소 2017 휴양및경관연구 (J East Asian Landscape Studies) Vol.11 No.3

This study analyzes residents’ views on rural resources and facilities necessary for rural resource development. The data utilized for the analysis is a questionnaire targeting local residents living in Yuchon-ri, Musu-ri, Yudeung-myeon, Sunchang-gun, and Jeollabuk-do. The analysis methods used herein include multi-attribute utility theory, to assess the importance of community resources; variance analysis to determine the importance of developmental directions; and multiple response and cross-analysis to analyze the facilities required for each project. The results are as follows: “Seomjin River”, “specialized crops”, “Oktaek creek”, and the “bike lane along Seomjin River” were rated highly as community resources. Respondents evaluated the developmental directions in descending order of importance, i.e., “cultivating specialized crops”, “fostering environmentally-friendly agriculture”, “processing agricultural specialty products”, “improving rural landscapes”, “revitalizing rural tourism and hands-on experiences” and “ameliorating living environments”. Regarding facilities required for each project respondents prioritized “expanding basic living grounds”, the establishment of “health care maintenance facilities” and the “expansion and paving of village roads”. Also frequently requested were “facilities for increasing local incomes”, the “direct transaction of agricultural products”, “facilities for processing agricultural specialty products” and “establishing a distribution system for agricultural specialty products”. Many respondents also expressed their need for “sales facilities” and “facilities for hands-on experiences” in order to “revitalize rural tourism”. With respect to facilities for “ameliorating local landscapes” respondents wished to “establish community symbolic structures”, “plant roadside trees”, “revamp vacant or deserted properties” and “tidy up the areas surrounding community centers.” Needs were identified such as “education for local residents”, “community leader- fostering training”, and “taking tours of advanced areas” in order to “enhance the capabilities of local areas”, Given such analysis results, it can be seen that local residents place greater emphasis on the rural resource developments whereby they can better increase their revenues. Respondents would like the developmental directions from which they can create value related to producing, processing, and experiencing specialty crops. In order to set the direction for the development of these rural, future research must meticulously examine the resources scattered through rural and create measures that can be directly linked to rural household incomes and regional revenues.

Comparison of Characteristics of Rural Landscape Plan in Rural Village Development Project - Focused on the Sunchang-gun -

Nara Jeong 전북대학교 휴양및경관계획연구소 2018 휴양및경관연구 (J East Asian Landscape Studies) Vol.12 No.3

The present study analyzes a case of a rural village development project to identify characteristics of rural landscape plans. The results of the analysis revealed that in the initial stage, rural landscape plans focused on renovating the livingscape, which included walls, vacant houses, and roofs. Beginning in 2010, landscape improvement projects were divided into areas such as the livingscape, and the village landscape, which included the natural landscape, ecological environment, and urban landscape, and planned to preserve the agricultural landscape and enhance under-developed landscapes. According to an analysis of the Sunchang-gun (a county in Jeollabuk-do, South Korea) area development project, the landscape improvement project was planned as a way of formation a new landscape. This indicates that the project was more focused on creating a new specialized landscape consisting of different areas, than it was on improving and maintaining the existing landscape. The livingscape, among all other components of the rural landscape, was addressed the most frequently by landscape projects, which placed emphasis on improving the landscape of the living environment, not the overall landscape of rural villages. Landscape improvement projects implemented tasks to highlight distinctive characteristics of the target area. For instance, the creation of a themed rest area or characteristic streetscape were treated with importance in all areas. However, landscape projects do not significantly contribute to shaping the overall rural landscape, as they focus on separate facilities instead of considering the overall rural landscape. Given that landscape projects constitute the only landscape-related effort in an area or village, they should be more heavily emphasized in rural village development projects.
