This research shows how fashion curation service consumers (both fashion and image consultants) reveal different aspects towards a preferred image type among the correlation of fashion curation service usage motivation and fashion shopping propensity. These preferences also included the purchase intentions for fashion display service products. This study surveyed 300 men and women between the ages of 20-30 who were the main consumers of fashion curation services. 'Convenience, fashion trend, and exploratory' increased purchase intentions for fashion shopping propensity, 'information search for utility, entertainment, and personal expression' increased purchase intentions for fashion curation services and 'brand identity, consumer lifestyle, and product information' increased factors for the fashion curation service preferred image type. Consumer preferences varied according to different fashion curation service image type; however, all consumer group syndicated a difference in fashion curation service actions. For instance, fashion curation service consumers preferred a consumer lifestyle image, convenience, hedonic shopping orientation, and personal expression motivation had a positive influence on product purchase intention. However, the shopping orientation of 'fashion trend, practical information exploration, and entertainment motivation' had an optimistic influence on product purchase intentions for fashion curation service consumers who preferred a brand identity image and a product information image.

Genome-wide Association Study of Susceptibility Loci for Self-Reported Atopic Dermatitis and Allergic Rhinitis in the Korean Population

김지우,Kim Min Jae,Paik Kyungho,Kim Bo Ri,Choi Chong Won,Na Jung Im 대한피부과학회 2024 Annals of Dermatology Vol.36 No.2

Background: Allergic diseases include atopic dermatitis (AD) and allergic rhinitis (AR), which are chronic, relapsing inflammator y disorders of the skin or mucosa that usually accompany immunoglobulin E-mediated immune responses. They are complex, multifactorial diseases with an etiology involving interactions between genetic and environmental factors. Objective: We performed a genome-wide association study (GWAS) to identif y single nucleo- tide polymorphisms (SNPs) associated with allergic diseases in the Korean population. Methods: A total of 8,840 samples were obtained from the Korean Association Resource Consortium dataset of the Korean Genome and Epidemiology Study Ansan-Anseong cohort. The allergic disease phenotype was determined based on self-reported physician diagnoses. After quality control, 8,823 subjects with 877,242 variants remained for the final analysis. The GWAS was performed using logistic regression analysis in an additive model adjusted for age and sex. Results: A total of 636 patients with allergic disease and 8,176 controls were analyzed. Three SNPs were associated with allergic disease at a level of genome-wide suggestive significance (p<1.0×10−5) in the Korean population: rs7275360, located in neural cell adhesion molecule 2; rs698195; and rs3750552, located in family with sequence similarity 189, member A2. These polymorphisms were on chromosomes 21q21.1, 7q31.1, and 9q21.12, respectively. Conclusion: We identified 3 novel SNPs significantly associated with allergic diseases in the Korean population. Further research is required to confirm the association between these novel SNPs and allergic disease in the Korean population and in other ethnicities.

흙의 종류와 다짐과의 상관관계

Compaction is defined as increasing soil densities. The main purposes of compaction are to reduce ground settlement by increasing the shear strength of soils and prevent water infiltration through earth dams by reducing permeability of soils. It is known that the efficiency of compaction is related to soil properties. Therefore, to understand the relationship between soil properties and compaction behavior is very important to compact ground efficiently. Compaction tests are performed to investigate the relationship between soil properties and compaction behavior for seven types of soils. Coarse grained soils are compacted well compared to fine grained soils according to compaction tests. Coarse grained soils with less clay contents and fine grained soils with high sand contents and low plasticity indices show higher compaction efficiency. The results obtained from this research can be used to improve the efficiency of compaction in the field.

수중 발열을 위한 Glass/Mo/ZnO/Glass 구조의 박막형 발열체 연구

김지우,최두호 한국마이크로전자및패키징학회 2022 마이크로전자 및 패키징학회지 Vol.29 No.1

In this study, we demonstrated an eco-friendly thin-metallic-film-based heater which can be operated in water. Based on the materials stability, Mo was selected as the heating element to secure long-term stability. Using a magnetron sputtering, 40 nm-thick Mo layers were deposited onto a glass substrate, followed by the deposition of 60-nm-thick ZnO layer to prevent oxidation during the heater fabrication process. Then, PVB (Polyvinyl Butyral) was applied on top of ZnO layer and an additional glass substrate was placed, which were heated at 150oC for 2 hr. The PVB was cured with strong adhesion by the processing condition. We operated the Glass/Mo/ZnO/Glass heater in water, and it was shown that the water temperature reached 50oC within 2 minutes, with a minimal resistance change of the heater. Finally, the heaters exhibit a semi-transparency, and this aesthetic advantage is expected to contribute to the added value of the heater. 본 연구에서는 보일러 등에 적용을 하기 위하여 물속에 담군 채 가열할 수 있는 친환경 박막형 히터에 대한 결과를 보고한다. 장수명을 확보하기 위하여 소재 안정성이 높은 Mo 박막(40 nm)을 마그네트론 스퍼터법을 이용하여Glass 기판상에 증착하였으며 후속 공정 진행 시 Mo 박막의 부식을 방지하기 위하여 상부에 ZnO 박막 (60 nm)을 형성하였다. 이후 투명 접착성을 가지는 PVB (Polyvinyl Butyral)를 이용하여 ZnO 박막 상부에 또 다른 Glass기판을 올려두고 열풍건조기 내에서 150oC의 온도에서 2시간동안 PVB를 경화시키며 접착시켜 Glass/Mo/ZnO/Glass 구조의 수중 히터를 완성하였다. 이렇게 제작한 발열체를 수중에 담근 후 발열 시 물의 온도가 2분 내 50oC까지 상승되는 것을 확인하였으며 미미한 수준의 저항증가가 발생하며 구조적 안정성 또한 확보되었다. 인가 전압의 세기에 따라 발열체의 온도가 제어되기 때문에 보일러에 적용할 때 사용자가 설정하는 온도를 용이하게 제어할 수 있을 것이라 기대된다. 마지막으로, 본연구에서 제작한 박막형 히터는 반투명의 특성을 가져 심미성을 부여할 수 있어 제품의 부가가치를 더욱 높일 수 있을것으로 기대된다.

The purpose of this study was to investigate the effect of robot-assisted upper limb rehabilitation training on hand and upper limb function in children with Moya-Moya disease. The intervention method used InMotion®RM, an upper limb-assisted rehabilitation robot, and the evaluation was conducted once each pre- and post-assessment, and the treatment was conducted 10 times for 30 minutes, a total of 12 sessions. The functional movement of the upper limb and hand was evaluated using the Jebsen-Taylor Hand Function Test and the program inherent in the InMotion®RM. The results were compared through a visual analysis using tables and graphs. After the training, the Jepson-Taylor Hand Function Test score improved in all areas, compared to the baseline. Evaluation using the program inherent in InMotion®RM showed improvement in the smoothness, accuracy, efficiency, and stability of upper limb movement. The results of this case study suggest that robot-assisted upper limb training is applicable to children with Moya-Moya disease and that it has a positive effect on improving the function and stability of the upper limb. In the future, more research subjects will be needed to study the method and effectiveness of robot-assisted upper limb training through group research. 목적: 본 연구는 모야모야병(MoyaMoya Disease) 아동에게 로봇 보조 상지 재활 훈련이 손과 상지 기능에 미치는영향에 대해 알아보고자 하였다. 방법: 본 연구는 모야모야병으로 인해 상지의 운동기능에 저하가 있는 아동을 대상으로 한 사례 연구(case report) 이다. 중재방법은 상지 보조 재활 로봇인 InMotion®ARM 을 사용하였으며, 중재 전과 후에 평가를 각 1회 실시하고치료는 30분씩 10회로 총 12회기 시행되었다. 상지 및 손의 기능적 움직임은 젭슨-테일러 손기능 평가도구(Jebsen - Taylor Hand Function Test)와 InMotion®ARM에 내재 된프로그램으로 평가를 실시하였다. 결과의 분석은 표와 그래프를 통한 시각적 분석을 통해 결과를 비교하였다. 결과: 로봇 보조 상지 훈련을 시행 전에 비해 중재 후에는상지의 기능적 움직임과 손기능을 젭슨-테일러 손 기능 평가도구로 측정한 결과, 모든 영역에서 점수가 향상되었다. InMotion®ARM에 내재 된 프로그램을 통한 평가 결과 상지 움직임의 부드러움, 정확도, 움직임의 효율성, 안정성이향상되었다. 결론: 본 사례 연구를 통해서 로봇 보조 상지 훈련이 모야모야병 아동에게 적용 가능성을 확인하였고, 상지의 기능과안정성 향상에 긍정적인 영향을 미치는 것을 확인하였다. 향후에는 더 많은 연구 대상자에게 그룹 연구를 통해 로봇보조 상지 훈련의 방법과 효과에 관한 연구가 필요하겠다.
