The Act on the Promotion of Mobility for the Transportation Vulnerable stipulates that the transportation vulnerable should be able to enjoy convenience when using public transportation. However, this law is not being implemented properly enough to bring up a petition saying, "Please allow the visually impaired to take a bus." Even if you try to use a call taxi for the disabled instead of public transportation, you have to apply and wait two to three hours. Therefore, this paper aims to design and implement systems for the vulnerable and their guardians, such as increasing the opening time of the ticket gate more than usual if the cane rings a notification on the bus and subway station designated using Bluetooth. Accordingly, it is expected to bring about effects such as the availability of public transportation, economic savings, safety guarantees, and prevention of missing children for the vulnerable.

The most common cause of foot drop is lumbar degenerative disc herniation, particularly at L4/5. We present a rare case of spinal cord injury accompanied by a thoracolumbar lesion that presented with bilateral foot drop. A 69-year-old male patient presented with sudden-onset severe bilateral leg pain and bilateral foot drop. Radiologic findings revealed T12 spondylitis compressing the conus medullaris. He had undergone vertebroplasty for a T12 compression fracture after a fall 6 months before. A physical examination showed bilateral foot drop, paresthesia of both L5 dermatomes, increased deep tendon reflex, and a positive Babinski sign. An acute bilateral L5 root lesion and a conus medullaris lesion were suspected based on electromyography. A surgical procedure was done for decompression and reconstruction. After the operation, bilateral lower extremity muscle strength recovered to a good grade from the trace grade, and the patient could walk without a cane. The current case is a very rare report of bilateral foot drop associated with T12 infectious spondylitis after vertebroplasty. It is essential to keep in mind that lesions of the thoracolumbar junction can cause atypical neurological symptoms. Furthermore, understanding the conus medullaris and nerve root anatomy at the T12-L1 level will be helpful for treating patients with atypical neurological symptoms.

A 6-year-old intact male Cane Corso dog weighing 40 kg with a 2-month history of dysuria, dyschezia, anorexia, intermittent panting, and penile discharge presented to the Veterinary Medical Teaching Hospital of Jeju National University. Examination revealed a giant paraprostatic cyst (PPC) that occupied a large part of the abdomen and caused displacement of organs. Radiography, ultrasound, and computed tomography (CT) scans confirmed that the PPC had spread to the pelvic regions. Subtotal resection was performed, leaving two sites with PPC remnants. One site was the prostate gland, which communicated with, and adhered to, the PPC; the other site was the pelvic region, where the PPC had spread. The reason for leaving two remnants was that an anatomical approach for complete resection was difficult, and to avoid complications associated with prostatic urethra damage. Routine omentalization and castration were performed. Partial cystectomy was performed because of the presence of a diverticulum-like lesion in the ventral part of the urinary bladder. The patient's clinical symptoms, including dysuria, completely resolved, and voluntary urination was possible 1 day post-operatively. Histopathological examination revealed osseous metaplasia of the PPC. The patient was well-managed and had no post-operative complications or recurrence until day 180 of follow-up.

A 67-year-old female patient diagnosed with acute transverse myelitis visited our hospital in February 2023. Consultation papers indicated that she was diagnosed with acute transverse myelitis and that she complained of quadriparesis and numbness in both hands and feet. However, her spine magnetic resonance imaging (MRI) did not clearly indicate that she suffered from acute transverse myelitis. She was then sent to a high-level hospital and diagnosed with Guillain-Barre Syndrome through electromyography, cerebrospinal fluid test, and spine MRI. On March 2023, she visited our hospital again, still complaining about weakness in both hands and inability to walk. She was treated with Korean medicine, including acupuncture, electroacupuncture, pharmacopuncture, and herbal medicine such as Yanggyeoksanhwatang and Sipimijihwang-tanggami. After three months, she was discharged on cane walking. The manual muscle test (MMT) grade of her upper limbs increased from 3-/3-/3-/3- (shoulder/elbow/wrist/fingers) to 4/4/4/3+, and the MMT grade of her lower limbs increased from 2/2/2/2 (pelvis/knee/ankle/feet) to 4/4/4-/4-. Her numbness in both feet disappeared, and her numbness in both hands decreased from a numeric rating scale of 7 to 2. No adverse events were reported during treatment. This case implies the therapeutic potential of Korean medicine for Guillain-Barre Syndrome, especially for those who had delayed diagnosis and missed the opportunity to get plasma exchange.

The development of sustainable smut management techniques requires an understanding of the impacts of smut on sugarcane growth and the relationships between smut intensity and meteorological variables, varieties, and crop types. Thus, assessments were made with the objectives to 1) determine the effect of smut on the above-ground growth of sugarcane, and 2) quantify the association of smut with weather variables, varieties and crop types. The effect of smut on above-ground growth was assessed in six fields planted with NCo 334 (wider coverage) having 6 months of age in Fincha and Metehara fields in 2021. Data on above-ground growth were taken from 20 randomly selected smut-affected and healthy stools from each field. Besides, 6 years' data (2015 to 2021) on the numbers of smut-affected stools and smut whips of 79 fields were collected. Furthermore, 10 years' (2011 to 2021) weather data were acquired from the sugar plantations. The results demonstrated reduction in the above-ground growth of sugarcane in the range of 18.39% and 73.42% due to smut. In addition, weather variables explained about 68.48% and 66.58% of the variability in the number of smut-affected stools and whips respectively. Smut intensity increased with crop types for susceptible varieties. The tight association between the smut epidemic and crop types, varieties, and weather, implied that these parameters must be carefully considered in management decisions. Continuous monitoring of smut disease, meteorological variables, varieties, and crop types in all the sugarcane plantations could be done as a part of integrated smut management in the future.

The soil moisture has an important effect on growth and development of highbush blueberry (HB), mainly because the root system, devoid of root hairs, is superficial. Moreover, the texture and organic matter content of Korean soil is different from the main producing counties, such as USA and Canada. To facilitate the growth and development of HB and long-term maintenance of productivity, the research related to soil moisture condition in Korea should be the priority. This study was performed to investigate the growth properties of the HB in various soil moisture conditions in order to determine the irrigation trigger point and optimum soil water potential. The texture of soil used in this experiment was loam. For the experiments, the soil was mixed with peatmoss at a rates 30% (v/v). Irrigation was scheduled at -3, -4, -5, -8, -15 and -22 kPa soil water potential then investigated leaf macronutrient, bush growth, and fruit properties. The leaf K content of HB showed the same trend in the soil water potential, but Leaf P and Mg content was highest in -5 and -22 kPa, respectively. The productivity and growth amount of HB showed the peak at the range of -4~-8 kPa as normal distribution pattern, and greatly decreased at above -15 kPa. Total dry weight and Cane diameter were highest at -4 kPa, plant width, fruit weight and yield were highest at -5 kPa, and plant height, cane number and shoot tension were highest at -8 kPa. Soluble solids content showed same trend in the soil water potential, but titratable acidity, anthocyanins and total polyphenols were not significantly different. Therefore, the optimal soil water potential for the development and a maximum production of HB were a range of -4~-8 kPa, and the recommended ideal irrigation trigger point was within -15 kPa.

To evaluate the effect of fiber sources on chewing activity, five sheep were consecutively fed diets containing 45% of a fiber source selected from 7 tested fiber sources of alfalfa hay cube(AHC), corn cob (CC), corn silage(CS), cotton seed hull(CSH), peanut hull(PHL), rice straw(RS) and sugarcane bagasse (SCB). Number of chew showed significantly higher value in CC(p<0.001) then other sources. RS and CC had highest(p<0.01) rumination times of 352 and 367 min/d, respectively. CC also showed the highest number of chew per kg NDF intake(p<0.01), but rumination time per kg NDF intake showed no difference except CSH(p<0.001). These results suggest that chewing activities were greatly affected by the fiber sources, and therefore it should be accounted in the formulation for ruminant feed.

The possibility of using rice gruel compared to that of the cane molasses as a source of readily fermentable energy for a urea supplemented straw diet has been studied. Twelve native growing bulls of $237{\pm}8.7kg $ live weight and months old were randomly allocated to three treatments fed solely rice straw enriched with : (1) 3% urea (US), (2) 3% urea + 15% molasses (UMS) and (3) 3% urea + 30% rice gruel (UGS). The feeding trial continued for sixty days. Organic matter (OM) intake was significantly (p < 0.05) higher in the UMS ( $64g/kg\;W^{0.75}/d$) followed by UGS ($53g/kg\;W^{0.75}/d$) and US ($49g/kg\;W^{0.75}/d$). Estimated (from digestible OM intake) metabolizable energy (ME) intake were 396, 348 and $301kJ/kg\;W^{0.75}/d$ for UMS, UGS and US respectively. The maintenance (i.e., no change in live weight) ME intake calculated to be $308{\pm}7.4kJ/kg\;W^{0.75}/d$. Urinary purine derivatives excretion was nonsignificantly higher in the UMS (51.73 mmol/d), followed by UGS (42.53 mmol/d) and US (35.26 mmol/d). The estimated microbial N (MN) yield were 21.10, 14.00 and 11.60 g/d for UMS, UGS and US respectively. For each MJ increase in ME intade, MN yield increased by $1.29{\pm}0.134g$. Observed live weight changes during the experimental period were 292, 125 and -19 g/d respectively for UMS, UGS and US. It was concluded that supplementation of readily fermentable N (urea) alone was not enough to optimize the rumen function and a source of readily fermentable energy was required. Rice gruel was less effective than molasses as fermentable energy source to remove a restriction on voluntary intake and provide less amino acids of microbial origin for absorption from the small intestine, Thus more substrate for protein synthesis and gluconeogenesis were available for growth in the molasses than the rice gruel supplemented animals. However, in situation where molasses is not available or costly, rice gruel does appear to have a place as readily fermentable energy source on a urea supplemented straw diet.

In order to produce clear and favorable citrus wine from Citrus unshiu produced in Cheju island, chemical and microbiological processes for alcoholic fermentation were investigated. The ratio of pressed juice passed below 100 mesh sieve and peel of mandarin orange were 55.9% and 25.6% respectively. Orange juice for fermentation source contained 8.85% total sugar, 1.43% total acid and 0.056% volatile acid. Pressed juice was adjusted to 24 degree Brix with cane sugar, and was fermented at $20^{\circ}C$ for one month. Starter screened and selected was Saccharomyces cerevisiae IAM 4274. As principal fermentation proceeded for one week, suspended solids began to precipitate slowly after then. After fermentation, clear citrus wine consisted of about 8 degree Brix residual sugar, $13.3{\sim}14.4%$ ethanol, $0.78{\sim}1.11%$ total acid, $0.05{\sim}0.07%$ methanol and $2.25{\sim}3.29%$ extract, was obtained. Color, flavor and taste of citrus wine found good with panel test. Citrus wine which was treated with fungal enzyme derived from Aspergillus niger CCM-4 was cleared much faster, and could be filtered more rapidly than the untreated. The enzyme-producing strain was isolated from field soil of Cheju island and identified.
