The distance fmm skin to the lumber epidural space was measured in 60 male patients receiving epidural analgesia. The mean distance was found to be 4.45cm. The epidural depths were identified most frequently at 4.0 to 4.5cm deep and over 90% of total cases were less than 5.5cm deep. The epidural depths had correlations with weight and PI(P $lt; 0.001), but not correlated with height.

Atopic dermatitis (AD) is a chronic inflammatory skin disease, and its prevalence is increasing. AD usually elicits skin barrier dysfunction, dry skin and itching. As the mechanisms of AD remain unknown, there is an urgent need to find effective therapies. Because of the diversity and complexity of marine environments, the discovery of drugs from marine organisms as novel therapeutic agents for human diseases has seen renewed interest. Dihydroaustrasulfone alcohol (WA-25), the synthetic precursor of austrasulfone, which is a natural product isolated from a Formosan soft coral, has been shown to possess many therapeutic effects in our previous studies. However, the detailed mechanisms and therapeutic effects of WA-25 on AD are incompletely understood. We performed in vitro and in vivo studies to examine the effects of WA-25 on AD. We showed that WA-25 blocks inflammation and oxidative stress. Simultaneously, we also found that WA-25 reduces the AD scores and AD-induced transepidermal water loss (TEWL), scratching behavior, and alloknesis. WA-25 is more effective in cases of AD than are the drugs that are currently used clinically. Importantly, we also found that when nucleophosmin (NPM) was inhibited or when its expression was reduced, the anti-inflammatory and anti-AD effects of WA-25 were blocked. These data suggest that NPM plays dual roles in inflammation and AD. Overall, these results suggest that WA-25 is a potential anti-inflammatory and AD therapeutic agent that is modulated by NPM.

3,4-Dihydroquinazoline 1 as T-type calcium channel blocker was in vivo evaluated against A549 xenograft in BALB/c-nu Slc mice, which exhibited 54% tumor growth inhibition through oral administration of 8 mg/kg of body weight and was slightly less active than doxorubicin (68%). In addition, this compound was also profiled for its acute toxicity to ICR mice to afford oral LD50 value of 1,038 mg/kg of body weight.
End-to-end Service Assurance in 5G Crosshaul Networks
Che-Chun Teng,Mei-Chun Chen,Min-Han Hung,Hong-Jie Chen 한국통신학회 2020 한국통신학회 APNOMS Vol.2020 No.09
More and more telecom operators around the world began to build and to deploy fifth-generation (5G) mobile networks. With the advent of 5G service scenarios, it brings new challenges and increases the complexity of management. To deliver good quality of experience of these 5G applications for customers, service assurance is important. In this paper, we propose an end-to-end service assurance solution for 5G crosshaul networks. The 5G crosshaul network architecture consists of fronthaul, midhaul, and backhaul networks. Our solution deployed in 5G trial network in Chunghwa Telecom in Taiwan. The solution focus on slicing service assurance and synchronization monitoring. Besides, our solution adjusts most of network management in the operation support system (OSS) to apply to 5G crosshaul network. Our goal is to provide stable 5G transport network and to assure quality of experience for customers.

By applying a magnetic field perpendicular to GaAs/AlGaAs two-dimensional electron systems (2DESs), we study the low-field Landau quantization when the thermal damping is reduced with decreasing temperature. Magneto-oscillations following the Shubnikov-de Haas (SdH) formula are observed even when their amplitudes are so large that the deviation to such a formula is expected. Our experimental results show the importance of the positive magneto-resistance to the extension of the SdH formula under the damping induced by the disorder.

Health benefits of evidence-based biophilic-designed environments: A review
Shih-Han Hung,Chun-Yen Chang 인간식물환경학회 2021 인간식물환경학회지 Vol.24 No.1
Background and objective: People-nature experiences, which suggest that humans seek connections between nature and other forms of life, were presented by biologist E. O. Wilson in 1984. Biophilic design attributes support environments that can improve human connections to nature. A significant amount of literature on environmental psychology provides empirical evidence that nature benefits humans, and that practical landscape and built environments can be designed to link humans and nature (e.g., the 14 biophilic design patterns). To date, however, there has been no well-done research on reviewing the health benefits of biophilic design. Methods: The paper provides a narrative review on biophilic design and human health. The scope of this article is limited to biophilic-design books and peer-review articles related to “biophilic design,” “evidence-based,” “benefits,” “health,” rather than an attempt to identify universal issues with biophilia hypothesis. Results: A total of 45 papers were included in our review, which was related to the top five biophilic design patterns and design: the presence of natural images, the presence of plants, visual and non-visual connections to nature, and material connection with nature. These studies were related to physiology and psychology through direct or indirect connections with nature and experiences in space and place. Conclusion: This study presents two important comparisons of the empirical research on biophilic design and human health that can explain the relationship of people-nature experiences to biophilic design and human health and provides insights into related researches and recommendations for future application of our findings.
Where Are Landscape Designers' Spatial Abilities in the Brain? An fMRI Study
Shih-Han Hung,Chia-Yi Huang,Tsung-Ren Huang,Shih-An Tang,Yu-Ping Tsai,Chun-YenChang 인간식물환경학회 2023 인간식물환경학회지 Vol.26 No.5
Background and objective: To effectively understand and communicate their work, landscape designers should possessexcellent spatial abilities. Neurological methods have confirmed that activation of the occipital lobe, parietal cortex, andprefrontal cortex affect the judgment of space; however, few studies have measured spatial abilities in landscape design. This study aimed to identify the potential role of various brain regions during spatial interpretation processes by landscapedesigners, particularly the effect of stimulating the frontal lobe on enhancing design capabilities. Methods: This study tested the spatial abilities of landscape designers when transforming a planar drawing into a sectionaldrawing and the brain regions activated in this process. The subjects were asked to identify the correct option whenmatching given section lines in a planar drawing. The correct answer rate and response time were used to score brainactivation during spatial task processes. A total of 16 valid subjects were divided into high- and low-accuracy groupsaccording to the correct answer rate. Results: The results for the high-accuracy group showed that the left inferior frontal gyrus was activated during spatialdesign tasks. In contrast, the findings for the low-accuracy group revealed that the left middle occipital gyrus was activatedfor processing visual information. Conclusion: The findings suggest that the frontal lobe plays a role in allowing landscape designers to make planar tocross-sectional inferences via mental rotations and categorical spatial relations. The findings offer implications forlandscape designers in stimulating the frontal lobe and enhancing their design capabilities.

Leiomyosarcoma is an uncommon tumor which arises from various sites including uterus, stomach, retroperitoneum, superficial soft tissues, bladder, kidney, and lung. Primary hepatic leiomyosarcoma is a very rare tumor and fewer than 70 cases of primary hepatic leiomyosarcoma have been reported since the first publication in Japan. And there was only one case report of cutaneous metastasis from hepatic leiomyosarcoma. We recently experienced a case of primary hepatic leiomyosarcoma presenting as subcutaneous palpable mass. Herein we report this case with a review of literatures. (Korean J Gastroenterol 2005;46:233-236)
