In a situation where the importance of eco-friendly fashion is growing, this study adds to the needed research by analyzing consumption value satisfaction factors, brand image, and repurchase intentions of eco-friendly fashion products. During the investigation, the impact of gender was also accounted for to establish an effective marketing strategy. In June 2024, 250 surveys were evaluated from domestic consumers with experience purchasing eco-friendly fashion products. Descriptive statistical analysis, factor analysis, reliability analysis, and regression analysis were performed. Five factors were measured to determine satisfaction with the consumption value of eco-friendly fashion products: emotional value, functional value, social and situational value, passive value, and rare and eco-friendly value. Empirically subdividing satisfaction with eco-friendly fashion as recognized by consumers reveals meaningful findings about consumption value. Among the factors of consumption value satisfaction with eco-friendly fashion products, functional value, social and situational value, and rare and eco-friendly value all positively affected repurchase intention. The consumer’s gender also made a difference in satisfaction. Considering these results, the marketing effect of eco-friendly fashion can be increased. This study will be able to increase the ESG management effect of fashion companies. By performing ESG management, the fashion industry can achieve social and environmental responsibility along with sustainable growth.

This study was aimed to determine the effects of grow media on the mineral contents of the leaves and growth characteristics of strawberry grown under aquaponics system in a plant factory. For aquaculture, 12 fish (Cyprinus carpio) (total weight, 2.0 kg) were raised in an aquaponics tank (W 0.7 m × L 1.5 m × H 0.45 m, 472.5 L) filled with 367.5 L of water at a density of 5.44 kg·m-3 and total 34 of strawberry seedlings were transplanted in the pots filed with 200 g of orchid stone, hydroball or polyurethane sponge in the growing bed (W 0.7 m × L 1.5 m × H 0.22 m) laid out with holly acrylic sheet (140×60 mm, Ø80) on the top of the system. The pH and EC of the aquaponic solution was ranged from 7.6 to 4.9 and 0.24－0.91 dS·m-1, respectively. The concentration of NO3-N was about 28% lower than that of the hydroponic standard solution, and K, Fe and B were 10, 27 and 3.8 times lower, respectively; however, the mineral contents of strawberry leaves were in the appropriate ranges with lower contents in the leaves grown with sponge media. The organic content (OM), nitrogen (N), phosphorus (P), and potassium (K) of the sludge were 61.5, 5.72, 8.92, and 0.24%, respectively. The leaf area, leaf number, and dry and fresh weights of shoot at 81 DAT were significantly higher in the hydroball, and the average number of fruits per plant was significantly higher in both the orchid stone and hydroball. There was no significant difference in the fresh and dry weights of fruits. Integrated all the results suggest that the orchid stone and hydroball media are more effective to utilize nutrients in solid particles of aquaponic solution, compared to the polyurethane sponge.

This study addresses the lack of comprehension data in second language acquisition research by focusing on English existential there-constructions (ETCs) with a locative extension (e.g., there is an X on the Y). The post-copular noun X used in the present study consisted of two types: actual and nonsense. Participants included 40 native speakers, as well as 40 advanced and 40 intermediate Korean learners of English, who completed an online picture selection task. In one picture, X was placed on the nearby Y; in another picture, X was placed on the far Y. The choice of both pictures was the correct response because ETCs are used to describe the existence of something regardless of its distance. There was a statistically significant relationship between English proficiency and the interpretation of ETCs. However, there was no relationship between the noun type and the interpretation of ETCs. In the Korean English curriculum, the distinction between expletive there and locative there must be emphasized.

본 연구는 2020년 5월부터 10월까지 4대강 사업의 하나로 준공된 8개의 낙동강 보 구간에 서식하는 저서성 대형무척 추동물의 생물다양성 변화와 군집분석을 수행하였으며, 2010년부터 2020년까지 약 10년간의 저서성 대형무척추동물 주요 분류군에 대한 변화상을 분석하였다. 조사결과 저서성 대형무척추동물은 총 3문 5강 18목 52과 83속 97종 128.1개 체/m2가 출현하였으며, 오염지표생물인 깔따구류(Chironomidae sp.)와 실지렁이류(Tubificidae spp.)가 전체적으로 우점하였다. 군집분석결과 우점도지수는 평균 0.62±0.20이고 다양도지수는 1.87±0.63로 낙동강 보 상류에서 가장 안정적으로 분석되었다. 낙동강 보 중앙부에서는 실지렁이가 우점하였으며, 칠곡보와 강정고령보에서 가장 불안한 군집구조가 나타났다. 군집안정성 분석결과 상대적 회복력과 저항력이 높은 특성군I이 높게 나타났으며, 저항력과 회복력이 낮은 특성군III이 소수 분포하는 것으로 나타나 현재 낙동강 보 구간의 군집은 매우 불안한 상태로 분석되었다. 섭식기능군에서는 잡아먹는무리가 비교적 높게 출현하였고, 썰어먹는무리, 모아먹는무리, 걸러먹는무리는 낮게 나타났 다. 서식기능군에서는 굴파는무리와 기어오르는무리가 우세하게 출현하여 대부분 용존산소가 낮은 정수생태계에서 출현하는 기능군들이 많이 분포하고 있는 것으로 나타났다. 주요 법적보호종으로는 상주보와 낙단보에서 멸종위기야생 생물 II급인 노란잔산잠자리(Macromia daimoji)가 분포하고 있는 것으로 확인되었다. 과거부터 10년간의 분석결과 종수와 개체수는 댐 공사 직후에는 증가하였지만, 2016년 이후부터 급감하면서 다시 안정화되고 있는 것으로 나타났다. 우점종으로는 깔따구류가 모든 지점에서 우점하는 것으로 나타났으며, 현재 약 50% 수준의 비율로 유지되고 있는 것으로 나타났다. EPT 그룹은 2011년을 기점으로 대폭 감소하였으며, 이중 강도래목과 날도래목은 회복하지 못하는 것으로 분석되었다. 오염지표생물인 실지렁이류는 2012년 공사 완료 후 증가 추세를 보였으며, 2015년과 2020년에 개체수가 폭발적으로 증가하였다. 멸종위기야생생물 I급으로 지정된 귀이빨대칭이(Cristaria plicata)는 2011년 합천창 녕보에서 출현 후 관찰되지 않았으며, 멸종위기야생생물 II급인 노란잔산잠자리는 2015년까지 7개의 구간에서 드물게 확인되었으나 현재 분포 서식처가 급격히 줄어든 것으로 확인되었다.

Supply chain management can be defined as an information system that connects the inside and outside of a company. Its purpose is to systematically and strategically manage the flow of information, resources and services to improve the long-term performance of the entire organization, including individual companies connected to the supply chain, and the quality of service provided to customers. The ultimate goal of SCM is to create synergy through organic integration of supply and demand based on cooperation and collaboration with stakeholders in the supply chain. This study is based on the hypothesis that the company's management performance will improve as the level of SCM improves. Most of the previous studies dealt with the relationship between corporate performance and SCM in the IT area. In this study, research was conducted through human capacity with IT system. The causal relationship was demonstrated, and there was a difference in the perception of the results of this study depending on whether or not smart factories were consulted in the era of the 4th Industrial Revolution. There is a need to examine the links between management's value chain and its causal relationship.

To analyze the synergistic effects of applying lavender aroma to a footbath, we analyzed the EEG and emotional responses of footbath, lavender inhalation, and lavender footbath in women in their 30s. Foot baths reduced wave activation, wave and wave inactivation, and SEF50 and SEF90. The foot bath activated waves by about 66% compared to the background EEG, and reduced SEF50 and SEF90 by 0.43 Hz-0.68 Hz and 3.7 Hz, respectively. Lavender inhalation activated α, β, and γ waves at a concentration of 1% or more, and inactivated θ waves. As the concentration of lavender inhalation increased, α waves increased and β and γ waves decreased. Lavender foot bath activates θ waves and α waves, and inactivates β waves and γ waves. Compared with the background EEG, the lavender foot baths reduced SEF50 and SEF90, which are the median frequencies of EEG power, 0.5 Hz and 3.4 Hz, respectively. Lavender showed a positive emotional response when applied to inhalation and foot bath. Lavender showed a positive emotional response when applied to inhalation and foot bath. When the lavender was inhaled at the concentration of 1~10% and the lavender foot bath was applied, the average preference index (API) showed 0.64~0.66 and 3.6 ± 0.6, respectively. Lavender oil has a greater synergistic effect on emotional reactions when applied to an aromatherapy bath than by inhalation. Lavender decreased SEF50 and SEF90 as the API increased. A lavender footbath was superior to lavender inhalation in both emotional and EEG responses, and was more relaxed and calming than a footbath. These results suggest that the aroma foot bath method, in which lavender is applied to a footbath, is more effective in terms of providing relaxation and calming than a footbath or lavender inhalation aromatherapy.

The purpose of this study is to investigate the effects of oxides (caryophyllene oxide, eucalyptol and linalool oxide), one of the major ingredients of essential oils, on odor intensity, electroencephalography (EEG) response and emotional response. The subjects were women in their twenties. Inhalation concentrations of oxides were varied from 0.01 to 10%, and EEGs were collected by Quantitative EEG. The odor intensity and average preference index (API) of the oxides were ranked in the order of eucalyptol > linalool oxide > caryophyllene oxide. Eucalyptol is a refreshing and pleasant substance that activates the brain (activation of β and γ waves and spectral edge frequencies (SEF50 and SEF90)). Linalool oxide has a calm and soft substance (activation of θ, inactivation of α, β, and γ waves) at a low concentration (<0.1%), and a fresh smell at high concentration (inactivation β and activation of θ and γ). Caryophyllene oxides were evaluated as a substance that is comfortable, soft, calm and sedating, which deactivates the brain (activation of α, inactivation of β and γ). Oxide materials showed a positive correlation between the odor intensity and the SEFs. Each of the oxides showed unique characteristics in the areas of odor intensity, emotional response, API, and EEG. These results give us a better understanding of the properties of the pure materials that make up a fragrance, and provide useful information for the manufacture of fragrance products or aroma oil blends with enhanced specific functions.

This study investigated the convergence of the QEEG and mood state changes in healthy females from teens to twenties on the inhalation of jasmine oil in different concentrations (0.01~100%). Brain activity upon stimulation by different concentrations was analyzed based on the RPVs and CVB, representing a rate of change compared with the background QEEG. The emotions elicited through jasmine were evaluated on a 20-point scale. The result of this evaluation showed that jasmine deactivated fast alpha but activated theta. In addition, it provided evidence for changes in the frequency band according to concentration. As concentration increased, the effect of alpha inhibition decreased, while the effect of inhibition of the high frequency band (20~50 Hz) increased. SEF50 and SEF90, which indicate the state of arousal, decreased as the jasmine concentration increased. Furthermore, it was assessed as having a pleasant, feminine, fresh and soft odor. Therefore, this study suggested that the inhalation of jasmine oil affected brain wave activities and mood states.

목 적: 크로마젠 렌즈의 색상별 시감투과율과 색상에 따른 근거리 시력과 선명도를 측정하여 비교 연구하기 위함이다. 방 법: 8가지 색상을 가진 크로마젠 렌즈의 분광투과율을 Shimadzu사의 UV-VIS Spectrophotometer(UV-2450)를 사용하여 측정한 후 380~780nm의 가시광선 전 영역에 대한 시감투과율을 구하였다. 대전 소재 K대학교 대학생 중에서 원거리 양안 교정시력이 1.0이상이 나오는 학생 총 30명 대상으로 800lux의 조명에서 40cm 근거리용 스넬렌 E시표를 이용하여 색상별 근거리 시력을 측정하고 가장 선명도가 좋은 색상과 가장 선명도가 떨어지는 색상을 선택하여 색상별 분포를 알아보았다. 결 과: 시감투과율은 Yellow 69.9%, Blue 69.1%, Violet 68.4%, Pink 63.5%, Aqua Blue 63.2%, Orange 61.5%, Magenta 52.2%, Green 46.2% 로 나타났다. 크로마젠 렌즈를 착용한 상태에서 Yellow와 Blue에서 가장 높은 시력이 측정되었고, Green과 Magenta에서 가장 낮은 시력이 측정되었다. 선명도가 가장 높은 색상으로는 Blue(30%)가 가장 많이 선택되었고, 선명도가 가장 낮은 색상으로는 Magenta(26.7%)로 많이 선택되었다. 결 론: 시감투과율이 높은 색상일수록 근거리 시력과 선명도가 우수하였다. 따라서 렌즈의 색상 선택 시시감투과율이 시력에 미치는 영향을 반드시 고려해야 할 것이다. 색상의 비교 분석에 따라 적절한 색상을 선택해야 한다.

Although neutrophils function in both defense and tissue destruction, their defensive roles have rarely been studied in association with periodontitis. We hypothesized that periph¬eral neutrophils are pre-activated in vivo in periodontitis and that hyperactive neutrophils would show enhanced phago-cytic ability as well as an increased production of reactive oxygen species (ROS). Peripheral blood neutrophils from patients with aggressive periodontitis and age/gender¬matched healthy subjects (10 pairs) were isolated. The levels of CD11b and CD64 expression on the neutrophils and the level of plasma endotoxin were determined by flow cytometry and a limulus amebocyte lysate test, respectively. In addition, neutrophils were subjected to a flow cytometric phagocytosis assay and luminol-enhanced chemilumines¬cence for non-opsonized Fusobacterium nucleatum in parallel. The neutrophilsfrom most patients expressed increased levels of both CD11b and CD64. In addition, the plasma from these patients tended to contain a higher level of endotoxin than the healthy controls. In contrast, no differences were found between the two groups with regard to phagocytosis or ROS generation by F. nucleatum. The ability to phagocytose F. nucleatum was found to positively correlate with the ability to produce ROS. In conclusion, peripheral neutrophils from patients with aggressive periodontitis are hyperactive but not hyperreactive to F. nucleatum.

Schizophyllum commune belongs to Schizophyllum, Schizophyllaceae, Agaricales, Agaricomycetes and Basidiomycotatina. The morphological shape of S. commune was similar with the cap, fan and hair. As for the sensory evaluation, chewness was not good for human's sensory. The major useful component was identified schizophyllan from S. commune extract. Schizophyllan has a great potential for developing medical supplies and functional foods. In our study, we carried out to internal transcribed spacer regions(ITS) for the specimens systematically. Also, we found out the optimal growth conditions of different temperature and media for S. commune cultivation. As the results of these test showed that when we compare with PDA, MCM and ME1 medium, we confirm that optimal temperature is 35℃ in MCM and ME1 medium. And optimal media of growth condition is ME1 and MCM.
