Sustainability index was calculated to determine the best management for rice productivity under long-term inorganic fertilizer management's practices. It is based on nutrient index, microbiological index and crop index related to sustainability as soil function. Indicators for calculating sustainability index were selected by the comparison of soil properties and rice response in paddy soil with fertilization. Total twenty two indicators were determined to assess nutrient index, microbiological index and crop index in order to compare the effect of different fertilization. The indices were applied to assess the sustainability with different inorganic fertilizer treatments such as control, N, NK, NP, NPK, NPK+Si, and NPK+Compost. The long-term application of compost with NPK was the highest sustainability index value because it increased nutrient index, microbial index and crop index. The use of chemical fertilizers resulted in poor soil microbial index and crop index, but the treatments like NP, NPK, and NPK+Si were maintained sustainability in paddy soil. These results indicate that application of organic and chemical fertilizer could be a good management to improve rice sustainability in paddy soil.

사회인프라 시설로 분류되는 LID(Low Impact Development) 시설은 지속적 유지 및 관리를 통하여 경관지속성과 기능지속성을 유지할 수 있다. LID 기법은 자연기반해법이기에 잡초, 폐기물 및 식생관리를 통하여 지속가능성을 확보할 수 있다. LID 시설은 도시에 분산적으로 설치되며 유지관리가 단순하기에 시민들의 참여를 통한 관리가 가능하다. 따라서 본 연구는 LID 시설의 현장조사를 통하여 LID 시설의 지속가능성에 영향을 주는 유지관리 인자를 도출하고 시민들의 참여도를 조사함으로써 유지관리에 대한 방안을 제시하고자 수행되었다. LID 시설의 경관지속성은 폐기물, 잡초관리가 중요한 인자로 도출되었으며, 기능지속성은 고사체 원인규명 및 관리와 적용토양과 식물종 선정이 중요한 인자로 도출되었다. 시민들은 LID 시설의 확대 및 관리, 조례제정 및 범국민 운동 참여 등에 대한 설문조사에서 모두 80% 이상의 높은 동의를 보였다. 일자리와 연계된 LID 관리 참여의향은 약 64%로 나타나 LID가 취약계층의 일자리가 될 수 있는 가능성을 보였다. LID의 유지관리는 비전문가도 쉽게 수행할 수 있기에 시설별 적은 비용으로 시민들의 참여를 유도할 수 있다. 시민들이 참여하는 유지관리 비용은 지자체의 LID 적용을 통해 저감된 사회인프라 관리비용과 정부의 사회복지 예산을 적용할 수 있을 것이다.

In Korea, which has three sides of the sea, various waterfront spaces are being developed and developed along with various coastal landscapes. However, there are a lot of cases that do not consider the regional characteristic of the coast or the characteristic of the coastal landscape. In many cases, the street facilities cause the landscape degradation and the use inconvenience because of incongruity with the scenery, aging and lax management. Therefore, it is necessary to reflect the specificity of the coastal landscape in planning and directing the street facilities, harmonizing with the surrounding natural environment, and consideration of sustainability. However, there is no research or planning index for sustainable street facilities considering the coastal characteristics. Therefore, this study suggests plan elements to improve the sustainability of the street facilities on the shore and proposes them as basic plan elements, and suggests what kind of improvements should be made to improve the sustainability of coastal facilities in Korea. Based on the plan elements derived from the plan, we checked the problems and complementary points of coastal street facilities in Korea by analyzing the current status of the street facilities around the Jeju Island beach from a sustainable point of view, and suggested plan indicators that should be supplemented to improve sustainability. We surveyed the street facilities such as walkway blocks, benches, pagoda, drinking fountain, trash cans, bicycle shelters, fences, guide maps, streetlights, and shower rooms in 10 beaches in Jeju Island. This study analyzed the sustainability characteristics of the each factor of these facilities by surveying the reflectivity of the 23 plan indicators from the six aspects derived from the sustainability planning factor as conformity, partial reflection, non - reflection, and nonconformity. The results of the analysis showed that the functional aspect was the highest with 68.3%, the material aspect (53%), the landscape aspect (22.3%), the productive aspect (14.7%) and the morphological aspect (12.2%), and maintenance / management (10.6%). In addition, the facilities with the lowest fitness in each aspect are bicycle shelter in landscape aspect, bicycle storage box and trash can in form aspect, shower room in material aspect, trash can in functional aspect, showroom, guide maps and drinking fountain in product aspect, showroom In maintenance aspect. In order to improve the sustainability of coastal facilities in the future, it is necessary to complement the administrative and landscape aspects. In coastal facilities, it is necessary to consider the sustainability planning index, especially for showers, taking into account the specificity of beaches. Consideration should be given to various aspects of sustainability for bike shelters and trash facilities. Through this study, we have proposed the plan elements to systematize, supplement, and improve the planning index for sustainability improvement in coastal facilities planning.

Using the nodY::lacZ fusion system in Bradyrhizobium japonicum USDA 110, 22 flavonoids, which have structurally different features, were tested to define the role of the substituted functional groups as an inducer or inhibitor for the nod gene expression. A functional ,group of 4'-OH on the B-ring and the double bond between 2-C and 3-C on the C ring were required to induce the nod gene expression in B. japonicum USDA 110. In the case of isoflavones, the 4'-methoxyl group, which blocks the open 4'-OH functional group, did not significantly lower inducing activity, as compared with isoflavones with 4'-OH. However, all flavonols tested, which have a 3-OH functional group on the C-ring, did not induce, but inhibited the nod gene expression. Flavone, 7-hydroxyflavone, and kaempferol (5,7,4'-trihydroxyflavonol) at $1\;{\mu}M$ concentration significantly inhibited the nod gene expression induced by 7,4'-dihydroxyflavone. However, 7-hydroxy-4'-methoxyflavone at $1\;{\mu}M$ concentration showed a synergistic effect with genistein and 7,4'-dihydroxyflavone on the induction activity.

Purpose: Consumers' experience of functional attributes is remembered, and the experience lowers the cost of consumers' input from their point of view and reduces uncertainty. It also plays an important role in consumers' positive emotions and responses. Accordingly, if information search costs are reduced in terms of the costs perceived by consumers about restaurants, a strategy differentiated from other companies can be established. Therefore, this study investigated the effect of functional congruence of restaurant stores on information search cost reduction, positive/negative emotions, and loyalty. Research Design, Data, and Methodology: This study investigated functional congruence, information search cost reduction, and positive/negative emotions. The structural relationship between loyalty was analyzed. To verify this, a research hypothesis was established based on previous studies and a research model was constructed. The questionnaire items were modified and used according to the current study, based on previous studies. The data were collected using the questionnaire method from 187 people who had dining out experience. Frequency analysis was performed to confirm demographic characteristics. Reliability, convergent validity, and discriminant validity of the collected data were verified. The research model was analyzed with a structural equation modeling (SmartPLS 4). Results: The findings show that functional congruence had significant positive effects on information search cost reduction and positive emotion, but no significant effect on negative emotion. Information search cost reduction had significant positive effects on positive emotion/negative emotion but did not significantly affect loyalty. Lastly, both positive and negative emotions had significant positive effects on loyalty. Conclusion: Based on transaction cost theory, this study found how functional congruence and information search cost reduction influence consumers' emotions. The functional attributes of restaurants were perceived by customers as information, thus uncertainty was decreased. Finally, appropriate management strategies and implications of functional congruence and information search cost in the restaurant were suggested.

일본 신도시는 1980년대 후반 자족성 강화를 위한 복합다기능화 정책이 추진되었음에도 불구하고 최근 초기개발지구를 대상으로 급격한 고령화와 시설 노후화에 따른 도시쇠퇴 문제가 대두되고, 이에따라 비영리법인을 중심으로 도시재생활동이 추진되고 있다. 아울러, 사업이 진행중인 지구는 택지처분 지난에 따른 낮은 인구정착율 문제가 지적되고 있다. 과연 이러한 현상이 신도시의 일반적인 문제이며, 일본 신도시의 복합다기능화 정책은 실패한 것일까? 신도시의 지속가능성을 위하여 어떠한 정책이 유효할 것인가? 이 점에 착안하여 본 연구는 자족성과 소셜믹스를 중심으로 동경권 대규모 신도시의 지속가능성을 고찰하였다. 본 연구를 통하여 본 동경권 신도시는 일부 쇠퇴지역이 존재하나 전체적으로는 타지역에 비하여 고령화율이 낮고, 인구가 증가하고 있음을 알 수 있었다. 하지만, 자족성지수로 살펴본 신도시는 자족성이 점차적으로 증가하고 있음에도 불구하고 주변교외지역 보다 높다고 보기 어려워 신도시 자체의 복합다기능화 정책의 한계가 나타났다. 또한, 신도시의 소셜믹스 평가결과 연령과 직업분포 등의 다양성이 낮게 나타났으며, 지구레벨의 다양성 분석결과 주택의 형태와 소유관계가 거주민의 연령과 직업의 편중에 영향이 있었다. 이러한 분석결과를 토대로 본 연구는 신도시의 지속가능성을 높이기 위하여는 도심 접근성, 주변산업과의 연계성을 고려한 입지선택이 매우 중요하며, 계획단계에서 거주민의 다양성을 증가시킬 수 있는 소셜믹스 계획이 필요하다고 판단하였다.

With increasing global interest in environmentally friendly materials and the consequent rise in demand, there is a growing need for alternatives to synthetic fibers, which can cause skin diseases and other side effects. The fashion industry is emphasizing material sustainability owing to concerns about increasing carbon emissions. Moreover, consumers express a strong desire for ecofriendly and sustainable materials. Therefore, clothing brand companies are developing eco-friendly products to enhance their corporate image. Hemp fibers are recognized for their functionality and are utilized as crucial materials in the development of eco-friendly products by global fashion companies. In this study, we produced socks that effectively improve foot health using hemp stem bark extract fibers and demonstrated the positive efficacy of natural fibers through functional and wearability evaluations. Hemp stem bark extract fibers showed 99.9% antimicrobial effectiveness against bacteria responsible for sweat-induced bacterial proliferation and odor, when blended with lyocell fibers and woven into fabric to manufacture socks. Wearability evaluations of these terry cloth socks confirmed a reduction in foot odor and fatigue among the participants with a consumer satisfaction of 4.63/5. These findings confirm the effectiveness and positive impact of the natural antimicrobial properties of hemp fibers and terry cloth structure in improving foot health.
