Objectives : To review RCTs on acupuncture treatment for low back pain in order to establish a standard acupuncture treatment model in treating low back pain. Methods : RCT articles on traditional acupuncture treatment for low back pain were searched through online database. Study Quality was assessed using the FEAS. Results : Ten out of the one hundred six articles searched were reviewed. Among the ten articles reviewed, six articles compared acupuncture treatment with no treatment or non-penetrating sham acupuncture. All six articles concluded significantly positive effect of acupuncture compared to the control. Conclusions : The ideal acupuncture treatment model for low back pain was obtained as follows. A sterile disposable stainless steel(0.30mm${\times}$40mm) should be inserted to more than six acupuncture points on the BL, GV and GB meridians such as $BL_23$, $BL_25$, $BL_40$, $BL_60$, $GV_4$ and $GB_30$. Sparrow pecking method to obtain 'de-qi' is recommended and repeated stimulation during the 20 minute retention time is necessary. Ideal treatment frequency would be more than one a week for about 7 weeks.

Metastasis is one of the hallmarks of malignant neoplasms and is the leading cause of death in many cancer patients. A major challenge in cancer treatment is to find better ways to specifically target tumor metastasis. In this study, the anti-metastatic potential of the methanolic extract of Rhizophora apiculata (R.apiculata) was evaluated using the B16F-10 melanoma induced lung metastasis model in C57BL/6 mice. Metastasis was induced in C57BL/6 mice by injecting highly metastatic B16F-10 melanoma cells through the lateral tail vein. Simultaneous treatment with R.apiculata extract (10 mg/kg b.wt (intraperitoneal) significantly (p<0.01) inhibited pulmonary tumor nodule formation (41.1 %) and also increased the life span (survival rate) 107.3 % of metastatic tumor bearing animals. The administration of R.apiculata extract significantly (p<0.01) reduced biochemical parameters such as lung collagen hydroxyproline, hexosamine, uronic acid content, serum nitric oxide (NO), ${\gamma}$-glutamyl transpeptidase (GGT) and sialic acid levels when compared to metastasis controls. These results correlated with lung histopathology analysis of R.apiculata extract treated mice showing reduction in lung metastasis and tumor masses. Taken together, our findings support that R.apiculata extract could be used as a potential anti-metastasis agent against lung cancer.

A design method of fuzzy modeling is presented for the model identification of route choice of traffic problems.The proposed fuzzy modeling implements system structure and parameter identification in the eficient form of""IF..., THEN-.."", using the theories of optimization theory, linguistic fuzzy implication rules. Three kinds ofmethod for fuzzy modeling presented in this paper include simplified inference (type I), linear inference (type 21,and proposed modified-linear inference (type 3). The fuzzy inference method are utilized to develop the routechoice model in terms of accurate estimation and precise description of human travel behavior. In order to identifypremise structure and parameter of fuzzy implication rules, improved complex method is used and the least squaremethod is utilized for the identification of optimum consequence parameters. Data for route choice of trafficproblems are used to evaluate the performance of the proposed fuzzy modeling. The results show that the proposedmethod can produce the fuzzy model with higher accuracy than previous other studies -BL(binary logic) model,B(production system) model, FL(fuzzy logic) model, NN(neura1 network) model, and FNNs (fuzzy-neuralnetworks) model -.fuzzy-neural networks) model -.

Objective: We have studied the effects of acupuncture and low level He-Ne laser therapy(LLLT) at $SI_3$, $BL_{40}$ on the tibial, sural nerve injury due to sports-damage or traffic accident and L5 spinal nerve ligature model like general herniation of nucleus pulposus(HNP) in a rat of neuopathic pain. Methods: A model of neuropathic pain was made by injuring tibial nerve and sural nerve while common peroneal nerve was maintained. Also, it was made by isolating left 5th lumbar spinal nerve. Three weeks after the neuropathic surgery, acupuncture and LLLT was injected at $SI_3$,$BL_{40}$ one time a day for one week. LLLT was divided three groups, that is LLLT-1(5mW), LLLT-2(10mW) and LLLT-3(30mW). After that, we examined the withdrawal response of neuropathic rats' legs by Von frey filament and acetone stimulation. And also we examined c-Fos, Nocieptin and KOR-3 in the midbrain central gray of neuropathic rats. Results: As we have observed the effect of mechanical allodynia, LLLT-3 group were diminished on 4 day, 5 day, 6 day and 7 day in the resection model compared with control model, LLLT-1 group were diminished on 5 day, LLLT-2 group were diminished on 3 day and 6 day, LLLT-3 group were diminished on 3 day, 4 day, 5 day, 6 day and 7 day in connected model compared with control group. As we have observed the effect of cold allodynia, LLLT-3 group were diminished on 7 day in the resection model compared with control model, LLLT-1 group were diminished on 6 day, 7 day, LLLT-3 group were diminished on 7 day in connected model compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, LLLT-3 were diminished in resection model compared with control group, LLLT-1 group were diminished in connected model compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, resection model were not increased compared with control group, LLLT-1 group and LLLT-3 group were increased in connected model compared with control model. As we have observed the effect of activity of KOR-3 in the central gray part, resection model were not increased compared with control group, LLLT-3 group were increased in connected model compared with control model. Conclusions: We have noticed that LLLT-1 and LLLT-3 group have more controllable effect than acupuncture group. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin and KOR-3 have effectively to control pain. Therefore We have to follow up about that.

Objectives : This research was performed to investigate the effects of Hwangryunhaedok-tang decoction and Hwangryunhaedok-tang Pharmacopuncture at BL10 on cognition and memory impairment in a mouse dementia model induced by scopolamine. Methods : Fifty ICR mice were divided into 6 groups : Normal group (n=5), Control group (n=9), Positive control group for pharmacopuncture group (n=9, Donepezil 0.75 mg/kg), Positive control group for oral administration group (n=9, Donepezil 5 mg/kg), Pharmacopuncture group (n=9, Hwangryunhaedok-tang Pharmacopuncture undiluted solution 10 ml/kg), and Oral administration group (n=9, Hwangryunhaedok-tang 200 mg/kg). For a mouse dementia model, 1 mg/kg scopolamine was intraperitoneally administered to ICR mice. Hwangryunhaedok-tang pharmacopuncture was administered on BL10 for 4 weeks at intervals of 2 days. Hwangryunhaedok-tang decoction was given orally for 4 weeks every day. Morris water maze and passive avoidance test were conducted followed by measurement of acetylcholine concentration, acetylcholinesterase activity, and the amount of BDNF and p-CREB in the brain. Results : 1. In the Morris water maze test, the time spent staying around the platform significantly increased in the pharmacopuncture group and oral administration group than in the control group. 2. In the passive avoidance test, the time spent in the bright room significantly increased in the pharmacopuncture group and oral administration group than in the control group. 3. The level of acetylcholine in brains increased in the pharmacopuncture group and oral administration group than in the control group. Also, the activity of acetylcholinesterase decreased in the pharmacopuncture group and oral administration group than in the control group. 4. The expression of BDNF and p-CREB decreased in the control group, but increased in the pharmacopuncture group and oral administration group. Conclusions : These results suggest that Hwangryunhaedok-tang decoction and Hwangryunhaedok-tang pharmacopuncture at BL10 may have cognition and memory-enhancing effect in scopolamine-induced dementia in ICR mice via controlling the content of acetylcholine and the activity of acetylcholinesterase, and activating BDNF and p-CREB.

Currently, NFTs have no dominant application except for the proof of ownership for digital content, and it also have small liquidity problem, which makes their price difficult to predict. Real estate usually has very high barriers to investment due to its high pricing. Real estate can be converted into NFTs and also divided into small value fungible tokens (FTs), and it can increase the the volume of the investor community due to more liquidity and better accessibility. In this document, we implement and design a system that allows ordinary users can invest on high priced real estate utilizing Black Litterman (BL) model-based Portfolio investment interface. To this end, we target a set of real estates pegged as collateral and issue NFT for the collateral using blockchain. We use oracle to get the current real estate information and to monitor varying real estate prices. After tokenizing real estate into NFTs, we divide the NFTs into easily accessible price FTs, thereby, we can lower prices and provide large liquidity with price volatility limited. In addition, we also implemented BL based asset portfolio interface for effective portfolio composition for investing in multiple of real estates with small investments. Using BL model, investors can fix the asset portfolio. We implemented the whole system using Solidity smart contracts on Flask web framework with public data portals as oracle interfaces.

This study examined the anti-diabetic effect of a silkworm extract in C57BL/6J mice, an ob/㏈ model, fed a high fat diet for 8 weeks. The body weight was not significantly different with the silkworm-extract supplement, nor did food intake and body weight gains also did not differ significantly among the high-fat diet groups. However, the water intake by the silkworm-extract supplemented groups increased significantly compared with that by the distilled-water supplement group, nonetheless, the FER did not differ significantly. For all groups, the blood glucose increased the most after 30 minutes and yet returned to a fasting level within 90 minutes. The fasting time and resulting glucose tolerance for the silkworm-extract supplemented groups were significantly decreased compared to that for the high fat diet with distilled water supplement group, while the level of blood glucose in silkworm-extract supplemented groups was significantly decreased compared with than in the diabetic control group. The HbA1c and insulin levels were no different among the groups. The sucrase and lactase activities in the proximal small intestine were significantly decreased in the silkworm-extract supplement groups compared to that in the diabetic control group. There was no significant difference in the glycogen contents in the liver and muscle among the groups. In conclusion, it was found that the silkworm-extract supplement repressed the disaccharidase activity in the small intestines mucosa of the C57BL/6J mice.

Objectives : The purpose of this study was to investigate how Rhei Radix et Rhizoma affects on insulin resistance and adipose tissue inflammatory response in high fat diet induced obese C57BL/6 mice. Methods : Obesity was induced in C57BL/6 mice by high fat diet for 12 weeks. Models were divided into 3 groups (n=6) of normal diet, high fat diet (HFD), and high fat diet with Rhei Radix et Rhizoma and investigated for 12 weeks. We measured body weight, FBS and oral glucose tolerance test (OGTT), serum insulin, homeostatic model assessment-insulin resistance (HOMA-IR), weight of liver and epididymal fat pad. Inflammatory markers such as adipose tissue macrophage (ATM), tumor necrosis factor-${\alpha}$ and interlukin-10 and CD68 of epididymal adipocyte were determined to evaluate the effect of Rhei Radix et Rhizoma on adipose tissue inflammation. Results : Compared with the HFD group, we observed loss of body weight and epididymal fat pad weight, improvement of glucose level and HOMA-IR, reduction of ATM and gene expression of TNF-${\alpha}$, CD68 in the high fat diet with Rhei Radix et Rhizoma group. Conclusions : This study suggests that Rhei Radix et Rhizoma has effects on insulin resistance and adipose tissue inflammatory response in high fat diet induced obese mice.

NDM hair tonic is composed of several plant extracts which are known to be used in oriental medicine. This study was carried out to investigate the effect of NDM hair tonic on hair regrowth in an alopecia model of C57BL6 mice. Hair of six-weeks old mice were trimmed by electric clippers and electric shavers, so as not to damage the skin. The next day, mice without visible scraches were selected, randomized and separated in groups of 6 mice. There were four experimental groups including saline (negative control), 50% ethanol (vehicle control), 3% minoxidil (MXD), and NDM tonic. The test compounds were topically treated with 0.15 $m\ell$ per mouse per day for 2 weeks. The hair regrowth was determined photographically and histologically and the quantity of endocrine factors, IGF-1 and TGF-$\beta$, in the skin of mice was measured by PCR. No clinical signs were found in all animals. The topical treatment of NDM tonic for 2 weeks to dorsal skin accelerated hair regrowth faster than either the controls or MXD treatment. The NDM tonic treatment also promoted hair follicle development and elongation as compared with the controls or MXD treatment. Both NDM tonic and MXD treatment significantly increased the expression of IGF-1 and TGF-$\beta$ in the skin of C57BL6 mice as compared with the controls (p<0.05). These results suggest that NDM tonic has a hair growth activity and be useful for the treatment of baldness or alopecia.
