Traditional department stores have been struggling to attract customers for several years. Many retail stores have closed in recent years, even before the COVID-19 pandemic. The reinvention of in-store shopping value and experience is imperative to attract customers and reinvigorate retail business. The purpose of this study was to discover which in-store components can improve customer experiences and loyalty while also identifying dissatisfaction issues in consumer experiences in department stores. The data was collected from two consumer groups-luxury department store (Selfridges) customers and mid-market department store (Debenhams) customers-to identify the types of value and experiences they seek most often. The findings showed that to enhance their store patronage, Debenhams should reposition their brand image in a way that allows customers to connect with their self-image and lifestyle by improving efficiency and convenience and prioritizing the utilitarian and social value types. By contrast, Selfridges should enhancetheir store atmosphere, visual merchandising and sensory experiences by maximizing slow retailing experiences and emphasizing the aspirational self-concept image for symbolic and hedonic value. This research uncovered the existence of numerous overlappingvalue dimensions, each of which contributed to the enhancement of the others. Several young customers expressed their support for ecologically responsible, cost-effective second-hand luxury products. Instead of focusing merely on conventional value dimensions, department retailers should determine how environmental and ethical objectives can be fulfilled. This study explained how department stores can craft their in-store environments to appeal to their customers' preferred value types to ensure success in a competitive market.

Attention is a fundamental aspect in the cognitive process of human. Cognitive system of human body requires to focus on selected information among a vast amount of information from sensory organs. It has widely studied that various environmental factors affected the level of attention; however, few researches have aimed to the effect of direct cryotherapy. In this research, level of attention was studied comparing sub-indexes of FAIR test between groups with different duration of direct cryotheapy to the back of neck. FAIR test is a evaluation tool for visual attention consisting of three sub-indexes. Selective attention, accuracy of attention, and persistence of attention can be independently analyzed by FAIR test. In the analysis of selective attention, cryotherapy for 5 to 20 minutes showed higher result than cryotherapy for 40 minutes. In the analysis of persistence of attention, cryotherapy for 5 to 15 minutes showed higher result than cryotherapy for 40 minutes. Overall, selective attention and persistence of attention turns out to be maximized between 5 to 20 minutes of cryotherapy and tends to decrease afterwards. However, accuracy of attention does not seem to be affected by the duration of cryotherapy. Correlation between selective attention and the skin temperature by cryotherapy tends to be negative supporting the findings by ANOVA and post-hoc test. Correlation between persistence of attention and the skin temperature showed similar results.

3D printing technology enables the production of creative and personalized food products that meet consumer needs, such as an attractive visual appearance, fortification of specific nutrients, and modified textures. To popularize and diversify 3D-printed foods, an evaluation of the printing feasibility of various food pastes, including materials that cannot be printed natively, is necessary. Most animal resources, such as meat, milk, and eggs, are not inherently printable; therefore, the rheological properties governing printability should be improved through pre-/post-processing or adding appropriate additives. This review provides the latest progress in extrusion-based 3D printing of animal resource-based inks. In addition, this review discusses the effects of ink composition, printing conditions, and post-processing on the printing performance and characteristics of printed constructs. Further research is required to enhance the sensory quality and nutritional and textural properties of animal resource-based printed foods.

연구배경 : 호흡곤란은 호흡기질환 환자의 가장 흔한 주소이나 이를 감지하는 정확한 기전은 아직 잘 알려져 있지 않다. 폐질환에서 호흡곤란의 심한 정도와 치료에 대한 반응을 측정하는 데 있어 객관적인 폐기능을 이용하여 왔으나 호흡곤란은 폐 환기능 뿐 아니라 심장, 폐질환, 심인적 요인 등을 반영한 복합적인 증상이므로 주관적으로 측정하는 호흡곤란지수(dyspnea index)를 사용하여 이러한 증상의 정도를 양적으로 측정하는 것도 유용할 것으로 생각된다. 방법 : 증상이 기관지천식 환자를 대상으로 Visual Analogue Scale(VAS) 및 Borg Scale Dyspnea Index (BSDI)와 Spirometry를 검사전 휴식상태, methacholine 유발검사에서 양성을 나타내었을 때, 기관지확장제 투여후 각각 측정하였다. 결과 : 1) 기저상태와 Methacholine 및 기관지확장제 투여후 시행한 폐기능검사 결과와 VAS 및 BSDI 간 상관관계는 없었다. 2) FEV1, FVC 및 MMFR 변화량과 VAS 및 BSDI 변화량 간에도 상관관계는 없었다. 3) 천식의 증상호소가 경미한 환자군이 증상호소가 심한 환자군 보다 methacholine 및 기관지확장제 투여 후의 VAS 및 BSDI의 변화가 더 컸다. 4) 호흡곤란지수중 VAS이 BSDI 보다 조금 큰 수치 및 변화량을 보였으며 두 지수 간의 상관관계를 볼 수 있었다(R=0.82). 결론 : 기관지천식 환자에서 기저상태 및 Methacholine 유발검사시에 객관적인 폐기능 검사 수치의 유의한 차이가 없음에도 불구하고 주관적인 호흡곤란지수는 변화하는 경향을 보였으며, 이는 경중 천식군에서 더욱 뚜렷하였다. 호흡곤란지수는 환자 간의 비교척도로는 사용될 수 없으나 한 환자에서 경과관찰이나 치료효과를 판정하는데에 spirometry와 함께 중요한 지표가 될 것으로 생각된다.

Objective: The purpose of this study was to investigate how light touch with a finger affects balance ability when a posture is maintained in the condition of visual information blockage and to provide a fundamental material for developing balance ability in the process of rehabilitation treatment. Design: Cross-sectional study. Methods: The study subjects were 17 healthy men and women in their twenties and thirties who were studying at S University in Seoul. The system was comprised of an equilateral triangular force platform. Subjects were asked to step on the foot position of the force platform (Good Balance, Finland) barefooted for 30 seconds, with eyes closed, hands hanging down loosely, and feet comfortably apart. It was connected to a laptop by using Bluetooth technology. An experiment was conducted in the following three circumstances: 1) no-touch trial, 2) light touch to the back (T7 area), and 3) light touch to the middle finger of the left hand. Each subject was given a 10-minute break between consecutive measurements. The experimental circumstances were performed randomly. Anteroposterior sway (APSV), mediolateral sway velocity (MLSV), and velocity moment (VM) were measured. Results: The APSVs (mm/s) were $9.32{\pm}3.37$ and $5.45{\pm}2.98$; the MLSVs (mm/s), $6.39{\pm}3.35$ and $3.31{\pm}2.48$; and VM ($mm^2/s$), $17.13{\pm}11.75$ and $6.76{\pm}8.31$ in the first and second experimental circumstances, respectively. APSV, MLSV, and VM values were significantly improved with the 1) no-touch trial and 2) light touch to the back trail conditions compared with the 3) light touch to the middle finger of the left hand condition (p<0.05). Conclusions: This study revealed that the balance ability for maintaining a body posture was influenced more by light touch to the back (T7) than by light touch with the sensitive fingertip and body sway diminished after visual information was blocked.

Objective: We investigated visual marbling level (VML) influence on pork loin physicochemical traits, consumer palatability responses, VML liking, purchase intent, and their relationships. Methods: For each of five slaughtering dates, at 24-h postmortem, nine paired Duroc castrated male boneless Longissimus dorsi (LD) muscles were categorized into low (LM, score 1 to 2, n = 3), medium (MM, score 3 to 4, n = 3), and high (HM, score 5 to 6, n = 3) VML. Meat physicochemical quality traits and consumer responses (n = 389) on palatability and VML liking, and purchase intent were evaluated. The experiment was in randomized complete block design. Analysis of variance, Duncan's multiple mean comparisons, and correlation coefficients were determined. Results: VML correspond to crude fat (r = 0.91, p<0.01), but both were reversely related to moisture content (r = -0.75 and -0.91, p<0.01, respectively). As VML increased, ash (p<0.05) and protein (p = 0.072) decreased, pH and $b^{\star}$ increased (p<0.05), but drip, cooking (p<0.05) and thawing (p = 0.088) losses decreased. Among treatments, muscle fiber diameter, sarcomere length, total and insoluble collagen contents, $L^{\star}$, and $a^{\star}$ did not differ (p>0.05). Compared to the others, HM had lower collagen solubility percentage (p<0.05), but similar (p>0.05) Warner-Bratzler shear force (WBSF). No differences (p>0.05) were found in juiciness, overall flavor, oiliness, and overall acceptability, but HM was more tender (p<0.05) than the others. Based on VML, consumers preferred MM to HM (p<0.05), while LM was similar to MM and HM (p>0.05). Corresponding to VML preference (r = 0.45, p<0.01), consumers (83%) would (p<0.01) definitely and probably buy MM, over LM (74%), and HM (68%), respectively. Conclusion: Increasing VML in pork LD altered its chemical composition, slightly increased pH, and improved water holding capacity, thereby improving its tenderness acceptability. Marbling might reduce chewing resistance, as lower collagen solubility in HM did not impact tenderness acceptability and WBSF. While HM was rated as most tender, consumers visually preferred and would purchase MM.
