This study was conducted to investigate the possibility of replacing imported Timothy hay (TH) with domestic Italian ryegrass silage (IRGS) as a horse feed considering feed quality, nutrient digestibility and feed price. Two experimental diets (TH and IRGS) were fed to six-headed Thoroughbred (body weight, 475.7±33.3kg) of the Korea Racing Authority of Wondang Stud Farm. The 3 head animals were assigned to Control group (TH) and Treatment group (IRGS), respectively. The nutrient digestibility was determined by the total collection method. IRGS is enough for using as a horse feed because its Relative feed value(RFV) was higher than TH and its fermentation quality is suitable for horses. Although no difference was observed in nutrient digestibility, Total digestible nutrients(TDN), and Digestible energy(DE) between Control and Treatment group (p>0.05), the fact that price of IRGS was much lower (53.7~62.4%) than that of TH indicates IRGS has competitive advantage over TH as a horse forage feed. The present study indicates that IRGS can be fully replaced with TH due to its superior economic value even though the similarity of its nutrient digestibility, TDN, and DE to TH.

Objectives: The purpose of this study was to discover the changes in obesity prevalence and dietary habits in Korean adults residing in various residential areas during the last 10 years. Methods: Data on Korean adults aged 19 years and above was obtained from the 4th (2007-2009) and the 7th (2016-2018) Korea National Health and Nutrition Examination Survey. The subjects were classified into metropolitan (4th: n=5,977, 7th: n=6,651), urban (4th: n=4,511, 7th: n=5,512) and rural (4th: n=3,566, 7th: n=2,570) based on their residence. The general characteristics, nutrient intake, intake amount, food groups, and healthy dietary factors were analyzed. The association between residential areas and obesity prevalence were analyzed by multiple logistic regression. Results: In urban and rural areas, the obesity rate increased in the 7th survey compared to the 4th survey, excluding the metropolitan area. The carbohydrate intake decreased, and lipid intake increased in the 7th survey compared to the 4th survey. Over the same period, the intake of cereals and vegetables decreased, and the intake of meat and processed foods increased. Rural residents had a higher intake of cereals and vegetables, and a lower intake of milk and processed foods than those in metropolitan areas and urban residents. The proportion of subjects who practiced a healthy diet increased in the 7th survey compared to the 4th survey. In the 4th survey, there was no relationship seen between the prevalence of obesity and the subject's residential area, but in the 7th survey, the odds ratio of obesity was higher in rural areas than in the metropolitan areas, confirming the regional gap (OR: 1.16, 95% CI=1.00-1.36, P=0.044). Conclusions: This study showed that the obesity prevalence increased in rural residents compared to metropolitan residents, indicating a gap between the regions. The nutrient intake and intake of food groups changed in the 10 years under consideration, and there were differences seen between regions. Therefore, it is necessary to formulate a policy that will reduce obesity prevalence and health inequalities between regions.

Objective: The aim of the study is to analyze female adult's body shape characteristics and to provide the basic information for clothing manufacturing. Background: The comparative study among the age groups is very fundamental to understand the body characteristics of each subjects group. Therefore, comparison of body measurements in age groups was applied in this study. Method: The study was fulfilled by the comparison between the data of the $5^{th}$ Anthropometry of Size Korea (2004) and the $6^{th}$ Anthropometry of Size Korea(2010). The subjects were 2,213 female adults aged 20~59 of the 5th Size Korea anthropometric survey and 2,025 female adults aged 20~59 of the 6th Size Korea anthropometric survey. Results: The differences indicated the decreased values in widths, depths, girths regarding the torso region and BMI. "Head height to Stature ratio" decreased significantly in the 6th data, on the other hand, "Crotch height to Stature ratio" increased in the 6th data. Through the distribution characteristic of the age groups by Stature groups, it was convinced that 160cm stature group is the most frequent among all age groups of the 6th Size Korea. Conclusion: As a summary, the meaningful differences were showed between the 5th anthropometric data and the 6th data. According to the 6th Size Korea, the distribution tendency of obesity is very similar to the 5th Size Korea data. But the percentage of obese women declined significantly. Application: These findings from the study can be utilized women's wear design and construction that reflect body characteristics.

The 6th industrialization, which is the policy strategy to combine the 1st, 2nd, 3rd agro-food industries in order to create synergy effects, is one of the most important policy strategies for the Korean government. Local governments as well as the central government, especially the Ministry of Agriculture, Food and Rural Affairs, have introduced various specific programs for the 6th industrialization. Among them, the 6th industry antenna shops located in Cheonan and Daejeon which were introduced by the Chungcheongnam-do Provincial Government to offer a better market place for 6th industry producers. However, few studies have been conducted to evaluate the performance of 6th industry antenna shops. The purpose of this paper is to analyze consumers' satisfaction of 6th industry antenna shops through survey and econometric modeling and to present some implications of the better operation of the 6th industry antenna shops. The results of the studies in this paper present some of the following findings: first, the overall level of satisfaction towards 6th industry antenna shops is high but consumers still claim some problems. Second, products which are sold at 6th industry antenna shops have important problems, including high prices and deficient product variety. Third, if these problems were fixed, the operation of 6th industry antenna shops would be successful and contribute to the development of 6th industrialization in Korea.

The $12^{th}$ rib syndrome is a disease that causes pain between the upper abdomen and the lower chest. It is assumed that the impinging on the nerves between the ribs causes pain in the lower chest, upper abdomen, and flank. A 74-year-old female patient visited a pain clinic complaining of pain in her back, and left chest wall at a 7 on the 0-10 Numeric Rating scale (NRS). She had a lateral fixation at T12-L2, 6 years earlier. After the operation, she had multiple osteoporotic compression fractures. When the spine was bent, the patient complained about a sharp pain in the left mid-axillary line and radiating pain toward the abdomen. On physical examination, the $10^{th}$ rib was not felt, and an image of the rib-cage confirmed that the left $10^{th}$ rib was severed. When applying pressure from the legs to the $9^{th}$ rib of the patient, pain was reproduced. Therefore, the patient was diagnosed with $9^{th}$ rib syndrome, and ultrasound-guided $9^{th}$ and $10^{th}$ intercostal nerve blocks were performed around the tips of the severed $10^{th}$ rib. In addition, local anesthetics with triamcinolone were administered into the muscles beneath the $9^{th}$ rib at the point of the greatest tenderness. The patient's pain was reduced to NRS 2 point. In this case, it is suspected that the patient had a partial resection of the left $10^{th}$ rib in the past, and subsequent compression fractures at T8 and T9 led to the deformation of the rib cage, causing the tip of the remaining $10^{th}$ rib to impinge on the $9^{th}$ intercostal nerves, causing pain.

The fused thoracic vertebra and deformity of the lumbar vertebrae in the female Thoroughbred horse were observed macroscopically. The 11th and 12th thoracic vertebrae (T) were partially fused. They were composed of three parts between the spinous process of the 11th and 12th T, left and right caudal articular processes of the 11th T, and left and right cranial articular processes of the 12th T. The vertical surface of cranial articular process of the 11th T and left mamillary process of the 12th T were absent. The left caudal part of the transverse process of the 12th T and left costal fovea of the transverse process of the 12th T were severely deformed. On the other hand, the left transverse process of the first lumbar vertebra (L) was a typical rib-like transverse process and two times longer than the right transverse process of the 2nd L. The right transverse process of 4th L has an oval concave facet on the medial part of caudal border for articulation with the right transverse process of 5th L; the latter has a corresponding convex facet on the medial part of the cranial border in the right transverse process of the 5th L.

Purpose: Previous studies have suggested that BDNF has a role in plasticity and survival following spinal cord injury and treadmill exercise increases BDNF levels in the normal brain and spinal cord. We attempted to determine whether swimming exercise improve motor function following experimental contusive spinal cord injury and whether motor outcome is associated with BDNF expression. Methods: Thirty six Sprague-Dawley rats (weight, 250 to 300 g) were divided into control (n=18) and experimental swimming group (n=18). Spinal cord injury was produced using NYU-spinal impactor at the eleven thoracic levels in both groups. Swimming exercise started $7^{th}$ day from SCI operation, lasted 5 min per day, 5 days a week for 4 weeks and then exercise times a day were increased in one number to each week. Motor functional recovery was determined by the Basso-Beattie-Bresnahan (BBB) locomotor rating scale, modified inclined board plane test, histological findings, H&E and BDNF expression observed at $1^{th}$, $3^{rd}$, $7^{th}$, $14^{th}$, $21^{st}$ and $28^{th}$day after injury. Results: 1. The BBB scores were higher in experimental group than control group at $14^{th}$, $21^{st}$ day (left hind limb) and at $21^{th}$ day (right hind limb) (p<0.05) after injury. 2. The inclined board plane test were significantly greater in experimental group than control group at $7^{th}$ day (p<0.05), $14^{th}$ and $28^{th}$ day (p<0.01) after injury. 3. The BDNF expression was severe revealed in experimental group than control group at $7^{th}$, $14^{th}$ and $28^{th}$ day after injury. Conclusion: This study suggests that swimming applied from the early phase after spinal cord injury be beneficial effects in motor functional recovery.

As the test results for surface color, dyeing durability, antibiosis of cotton fabrics and silk fabrics dyed with Agastache rugosa extract, the following conclusions were obtained. The surface color of all the dyed fabrics was confirmed mostly as a GY system. As the result of chrominance(${\Delta}E_{ab}$) measurement, in the case of cotton fabrics the dyed fabrics treated with $Al_2(SO_4)_3$ mordant showed the highest value and in the case of silk fabrics the non-mordant dyed fabrics showed the highest value. The dyeing durability of test fabrics dyed with Agastache rugosa extract are as follows. As the test results of colorfastness to laundry for cotton dyed fabrics, the discoloration degree showed 1st-2nd grade and the contamination degree showed 4th-5th grade. As the test result of colorfastness to dry cleaning for silk dyed fabrics, the contamination degree showed from 1st to 3rd-4th grade. As the test results of colorfastness to acid artificial perspiration, the discoloration degree showed from 1st to 3rd-4th grade and the contamination degree showed from 3rd to 4th-5th grade. As the test results of colorfastness to alkaline artificial perspiration, the discoloration degree showed from 1st to 4th grade and the contamination degree showed from 3rd to 4th-5th grade. The colorfastness to sunlight showed from 1st to 2nd grade. The colorfastness to rubbing showed from 3rd to 4th-5th grade in dry process and from 2nd-3rd to 4th-5th grade in wet process. As the test results of antibiosis, the decrease rate of germs to virus Klebsiella pneumoniae and Staphylococcus aureus showed at least more than 99% after the wash of 10 times. As the test results of antifungal activity to mycete Trichophyton mentagrophytes and Aspergillus niger, the both cotton and silk dyed fabrics didn't gain the significant antifungal effect.
