This study aimed to investigate the influence of Astragalus membranaceus (AM), Adenophora triphylla (AT), and Ulmus pumila (UP) extracts on the quality traits, palatability, and storage stability of sous-vide (SV) cooked chicken breasts. Chicken breasts were marinated in AM, AT, or UP extracts for 1 h, and then consistently cooked at a constant temperature of 60℃ for 2 h. SV cooked chicken breasts with the UP extract exhibited lower lightness and higher yellowness values on the surface region compared to those with the AM and AT extracts (p<0.05). The control and UP groups displayed a similar overall visual acceptability (p>0.05), although the UP group had lower color acceptability (p<0.01). The UP group also had higher flavor and lower off-flavor intensities compared to the control group (p<0.05), although similar scores were observed in tenderness attributes and juiciness among the groups (p>0.05). Owing to these results regarding overall sensory acceptability, samples from the UP group were more preferred by the trained panelists compared to samples from the control group (p<0.001). On 14 d of cold storage, all the groups with herbal medicinal extracts exhibited a lower concentration of thiobarbituric acid-reactive substances than the control group (p<0.05), and the AT and UP groups showed lower values compared to the AM group due to their higher flavonoid contents (p<0.001). Therefore, meat marination with herbal plant extracts before SV cooking can be effective for enhancing the overall quality of SV cooked chicken breast.

Objectives The objective of this study was to assess the effectiveness of acupotomy for carpal tunnel syndrome. Methods Based on seven domestic and foreign databases. We analyzed the randomized controlled trials using acupotomy for carpal tunnel syndrome. The treatment group was treated with acupotomy and the control group was no restrictions on treatment methods. Results In this study, the effect of acupuncture treatment for carpal tunnel syndrome was investigated. Each study reported that acupotomy could be an effective treatment for carpal tunnel syndrome. However, as a result of meta-analysis of Levine carpal tunnel syndrome questionnaire scores, visual analog scale, and sensory nerve conduction velocity, the results were more clinically significant than those of the control group. Due to the small number of randomized controlled trial studies and the nature of acupotomy treatment, blinding of interventions was impossible, resulting in a high risk of bias. Conclusions In this regard, it is thought that well-planned randomized controlled studies on patients with carpal tunnel syndrome are needed in the future to secure the clinical evidence for acupotomy treatment.

메타버스의 시대가 다가옴에 따라 해결해야 하는 난제가 있다. 그 중 '사이버 멀미'는 VR 기술이 주목받기 시작한 2016년부터 현재까지 VR의 대표적인 문제점이다. 감각 갈등이론에 따르면 멀미는 지각되는 운동 방향 정보와 기댓값이 같지 않을 때 유발한다. 본 논문은 뇌인지와 사이버 멀미의 상관관계에 대해 이론적으로 탐구하고, 이를 바탕으로 사용자의 몰입도가 멀미 증상에 미치는 영향에 관하여 연구하였다. SSQ 실험을 통해 카메라의 회전 값이 시청자의 사이버 멀미 증상을 악화시킨다는 점과 시청자가 해결해야 할 시각적·변속적 미션을 줌으로써 게임의 몰입도를 높여 사이버 멀미를 완화할 수 있다는 사실을 입증하였다. 본 연구는 VR 리듬 게임인 "beatale"을 개발하는 과정 중 사이버 멀미 문제를 해결하고자 진행되었으며, 해당 프로젝트 개발뿐만 아니라 향후 VR 콘텐츠 제작 시 사이버멀미를 개선하기 위한 기반이 될 것으로 기대된다.

Convergence, a universal phenomenon in modern society, takes place in various ways throughout society, and the concept of convergence can also be observed in fashion shows. The concept of convergence is actively emerging in terms of fashion show directing. The purpose of this study is to suggest the development of fashion show directing by analyzing the convergence characteristics of fashion show directing through a Louis Vuitton fashion show, and to provide data on convergence in fashion shows. The object of the study is the women's Paris Pret-a-porter and women's cruise collection presented at the Louis Vuitton fashion show. The research method integrated the criteria for analysis and the characteristics of fashion show production through previous studies and a literature review. The characteristics of convergence production in Louis Vuitton fashion shows were identifeid through literature and visual data. In this study, the convergence of the Louis Vuitton fashion shows were divided into four categories: genre integration, sensory synesthesia, perspective diversification, and media scalability. First, the integration of genres enhanced the brand image and effectively conveyed the concept of the show. Second, the synesthesia of the senses expanded communication with the audience and increased the audience's immersion. It has also become a new way to experience fashion shows in person. Third, the diversity of perspectives changed and diversified the way audiences experienced fashion shows. Fourth, the scalability of the media means various ways in which the audience can experience fashion shows. Through this, it is possible to effectively convey information and experiences about fashion shows to the audience.

Objective: The purpose of this study is to evaluate the usefulness of infrared thermography in patients with carpal tunnel syndrome by comparing with electrodiagnostic and ultrasonographic findings. Method: From January 2014 to October 2017, electrodiagnosis, ultrasound, and digital infrared thermal image (DITI) of unilateral carpal tunnel syndrome diagnosed in a single hospital were retrospectively analyzed. The subjects with bilateral symptoms of carpal tunnel syndrome, peripheral vascular disease, diabetes, thyroid disease, fibromyalgia, rheumatic disease, systemic infection, inflammation, malignant tumor, and other musculoskeletal disorders such as finger osteoarthritis, peripheral neuropathy, cervical radiculopathy, and the previous history of surgery were excluded. Results: Of 53 patients diagnosed with carpal tunnel syndrome, 11 were male and 42 were female. The visual analogue scale was 4.9 ± 1.9, and the duration of symptom was 11.8 ± 12.5 months. There was no statistically significant difference in the body surface temperature between the unaffected and affected sides. The severity of symptoms, electrodiagnostic findings, and cross-sectional area of the median nerve significantly correlates to each other. The temperature difference between the second fingers of the affected and unaffected sides showed a weak correlation with the amplitude of sensory nerve action potential and onset latency of compound muscle action potential, when there was no significant correlation with the other parameters. Conclusion: The difference in temperature on the surface of the body, which can be confirmed by DITI, is little diagnostic value when DITI is performed in unilateral carpal tunnel syndrome patients, especially when compared with ultrasonography.

Purpose: Gestational nutrition has an impact on the growth and development of the fetus. Choline (C) and docosahexaenoic acid (DHA) are important and essential nutrients for humans that play a role in the structural integrity of the membranes as well as signalling. C is used in the synthesis of phosphatidylcholine, and cell membranes are highly enriched with DHA. The dietary intake of C or DHA during pregnancy directly influences fetal development. Currently, there is no evidence to prove the effectiveness of the combined dietary supplementation of both C and DHA during gestation on developmental outcomes in the offspring. Methods: The current study was designed to assess the physical, sensory, and motor development of rat pups born to mothers supplemented with C and/or DHA during the entire gestational period. Pregnant rat dams were divided into the following five groups: Normal control (NC), Saline control (SC), Choline (C), DHA, and Choline+DHA (C+DHA). The NC dams did not receive any supplementation during the entire gestation period. The experimental groups were supplemented with Saline, C, and/or DHA, respectively, during the entire gestation (E0 to delivery). Results: Rat pups (n = 6/group) exposed to combined C and DHA showed significant improvement in birth weight, fur development, eye-opening as well as weight gain on the 7th, 14th, and 21st postnatal day and pinnae detachment (assessed from birth to postnatal day 21) when compared with age-matched NC, SC or C or DHA pups. Further, significant reflex responses were observed in visual placing and bar holding of pups exposed to both C and DHA, whereas the differences in surface righting, negative geotaxis, and grasping reflexes were not significant between the groups. Conclusion: Gestational supplementation of both C and DHA rather than either of them alone is better in enhancing developmental outcomes in rat pups.

This study aims to compare and evaluate the usability of domestic and overseas XR devices. With the recent release of 'Apple Vision Pro', interest in the XR field is increasing rapidly. XR devices are being used in various fields such as defense, medical care, education, and entertainment, but the evaluation system for evaluating usability is still insufficient. Therefore, this study aims to derive improvements in domestic equipment through comparative evaluation of usability for two HMD-type devices and one glasses-type device that are released. In order to conduct the study, 20 participants in their 20s to 30s who were interested in XR devices and had no visual sensory organ-related disabilities were evaluated by wearing VR equipment. As a quantitative evaluation, electromyography through an EMG sensor and the device and body temperature of the device through a thermal imaging camera were measured. As a qualitative evaluation, the safety of wearing, ease of wearing, comfort of wearing, and satisfaction of wearing were evaluated. As a result of comparing the usability of the devices based on the results, it was confirmed that domestic HMD-type device needs improvement in the strap part.

Background and Purpose: Episodic memory is a system that receives and stores information about temporally dated episodes and their interrelations. Our study aimed to investigate the relevance of episodic memory to time perception, with a specific focus on simultaneity/order judgment. Methods: Experiment 1 employed the simultaneity judgment task to discern differences in time perception between patients with mild cognitive impairment or dementia, and age-matched normals. A mathematical analysis capable of estimating subjects' time processing was utilized to identify the sensory and decisional components of temporal order and simultaneity judgment. Experiment 2 examined how differences in temporal perception relate to performance in temporal order memory, in which time delays play a critical role. Results: The temporal decision windows for both temporal order and simultaneity judgments exhibited marginal differences between patients with episodic memory impairment, and their healthy counterparts (p = 0.15, t(22) = 1.34). These temporal decision windows may be linked to the temporal separation of events in episodic memory (Pearson's ρ = -0.53, p = 0.05). Conclusions: Based on our findings, the frequency of visual events accumulated and encoded in the working memory system in the patients' and normal group appears to be approximately (5.7 and 11.2) Hz, respectively. According to the internal clock model, a lower frequency of event pulses tends to result in underestimation of event duration, which phenomenon might be linked to the observed time distortions in patients with dementia.

이 연구는 애니메이션의 재미가 어떻게 구성되는지를 이론적으로 검토하고 조작화 한 후, 애니메이션의 재미를 강화시켜 줄 수 있는 구조를 제안한다. 그리고 제안한 재미모델을 검증하여 애니메이션의 재미가 어떠한 방식으로 작동하고 있는지를 살펴보는데 의미가 있다. 재미에 대해 이론적으로 검토한 결과 애니메이션의 재미는 감각적 재미, 인지적 재미, 심리적 재미로 구성된다고 조작화할 수 있었다. 감각적 재미는 시각, 청각등의 감각적 정보를 통해 유발되는 재미로, 감각적 재미에 직접 영향을 주는 요소로는 이미지, 사운드, 움직임이 있다. 인지적 재미는 감각적으로 지각된 자극을 자신이 가지고 있는 지식을 동원하여 능동적으로 추론하고 해석하여 얻어지는 재미로 스토리를 인지적 재미의 요소로 보았다. 심리적 재미는 관객이 애니메이션을 관람할 때 발생하는 심리적 정체를 해소함으로써 재미를 경험하는 심리적 감정 상태로 동일시나 낯섦의 재미로 구성된다. 애니메이션의 재미를 구성하는 감각적 재미, 인지적 재미, 심리적 재미가 서로 어떠한 영향을 미치는 가에 대해 연구모델을 검증한 결과, 감각적 재미가 인지적 재미와 심리적 재미를 강화시킨다는 것을 알 수 있었다. 물론 인지적 재미도 심리적 재미를 강화시키는 것으로 나타났으나, 감각적 재미가 인지적 재미보다 두 배 이상 심리적 재미를 강화시키는 것으로 나타났다. 또한 감각적 재미가 심리적 재미에 영향을 미칠 때 인지적 재미가 매개변수로서 간접효과를 나타내고 있음을 알 수 있었다. 따라서 감각적 재미는 심리적 재미에 직접적으로도 영향을 주지만 인지적 재미를 통해서 더욱 강화된다는 것을 보여주고 있다. 애니메이션의 재미란 감각적 재미와 인지적 재미, 심리적 재미가 하나로 융합되어 작용할 때 경험되어지는 것이다. 따라서 어느 한 재미요소만을 부각시킨 애니메이션은 관객에게 사랑받기 어렵다. 애니메이션의 재미요소인 스토리, 이미지, 사운드, 움직임의 조화로운 결합을 통해 재미감정을 유발시켜 심리적으로 재미있게 만드는 일이 중요하다.
