A 3 year-old female Afghan hound came to the Veterinary Referral Hospital of the College of Veterinary Medicine, Seoul National University for artificial insemination (AI) with frozen semen. In order to inseminate, semen was frozen in USA 3 years ago. Frozen semen was sent by air from Santiago to Seoul for AI. The stud died 2 years ago, so we could only use a limited amount of frozen semen in that estrus cycle. The number of total motile spermatozoa was $59.4{\times}10^6$and the total volume was 1.2 ml. The frozen spermatozoa were thawed in $70^{\circ}C$ water for 8 sec, which were then deposited at the bilateral uterine horns by a surgical method. The number of corpus luteum was 6. Sixty days after artificial insemination resulted in the birth of 4 puppies, all of which are alive and healthy.

A 5-year-old female lion-head rabbit weighing 2 kg was brought to a local animal hospital with hematuria. Radiography showed a mass in the uterus, which was removed by ovariohysterectomy. Macroscopic examination showed several masses in both uterine horns. These masses, which invaded the deep uterine walls, were firm to the touch, and their cut surfaces were greyish-white in color. Histopathologically, these masses were nonencapsulated and were composed of spindle cells arranged in cellular, large interlacing bundles or streams. The tumor cells had elongate nuclei with prominent nucleoli, granular chromatin and eosinophilic cytoplasm. Moderate anisocytosis and anisokaryosis were observed. Severe and extensive inflammation and necrosis were present within the masses. Immunohistochemically, the neoplastic cells were positive for vimentin, desmin, and α-smooth muscle actin, but negative for cytokeratin. These uterine masses were diagnosed as leiomyosarcoma. To our knowledge, this is the first report of a uterine leiomyosarcoma in the rabbit in Korea.

An 8-months-old young Maltese bitch was presented for investigation of anorexia and occasional vomiting. The body weight was 2 kg. Abdominal sonography demonstrated abnormal enlargement of uterus. The dog had been clinically and pathologically examined. Also, ovariohystectomy was performed. Staphylococcus aureus was identified in the pus-like materials of the uterine lumen. This case was confirmed as pyometra induced by Staphylococcus aureus. Gross examination of the dissected uterus revealed enlarged uterine horn, which had yellowish or brownish pus-like materials in the lumen. Also, there was several segments formation between the enlarged areas of left and right uterine horns. Histopathologically, endometritis and necrosis were present in uterine wall. The bitch made a complete recovery following an ovariohystectomy. This case was spontaneous pyometra induced by Staphylococcus species. On our knowledge, this is a very rare report of pyometra occurrence in young dog and Staphylococcus species-induced pyometra. This study may provide a valuable data on the study of canine pyometra.

The purpose of this paper is to understand the ethnic characteristics of official uniforms of Qing(淸)) by comparing the rank systems of official uniforms of Ming(명(明)) and Qing(淸)) dynasties. As research documents, Dai-Ming-Huidian(大明會典)) and Qing-Huidian-Tu(淸明會圖)) have been used. This research shows that there are many traditional characteristics of Manchurians (滿族)) in the official uniforms of Qing(淸)) dynasty. The characteristics are as follows: First, Qing dynasty made their own official uniform based on the traditional Manchurians(滿族)) costume, and added rank system on it. Second, Qing dynasty used the animal's leather as the material of official uniforms and distinguished the level of the uniforms according to the rerity value of rareness, color, and warmth of the leather. Third, Qing dynasty used pearls produced in Manchuria as the highest level, as opposed to jades and rhinoceros horns of Ming. Fourth, Qing dynasty eliminated the animal's rank system of twelve patterns which had been used for whole history of China, but the Emperor is the only man who is able to use twelve patterns. Qing dynasty made her own pattern system of standstill/moving dragons and standstill/moving pythons. Fifth, Qing dynasty used the rank system by colors in the order of yellow, red, and blue consistently over various official uniforms, while Ming used different color orders for different uniforms.

Ultrasonic transmitter used for scale prevention in boiler or heat exchanger is composed of the magnetostrictive material which transforms electric energy into ultrasonic wave and the horn which amplifies generated ultrasonic wave and transfers it into medium loaded. In this paper, we have performed the shape design for magnetostrictive material and analyzed a few type of horns which amplify generated ultrasonic wave and found each solution theoretically. Final length of the horn has been determined by measuring the sound pressure in medium between theoretical value and experience data. At last we have given the results of our study for the effects of ultrasonic wave irradiated by manufactured ultrasonic transmitter on preventing scale deposition on test pipe under the similar condition to boiler.

When cavity floor is near the pulp, polymerization of light-activated restorations results in temperature increase. This temperature increase cause by both the exothermic reaction process and the energy absorbed during irradiation. Therefore instating base is required. Most frequently used insulating base is glass ionmer. The purpose of this study was to evaluate intrapulpal temperature changes of glass ionomer according to various curing intensity and curing time. Caries and restoration-free mandibular molars extracted within three months were prepared Class I cavity of 3$\times$6mm with high speed handpiece. 1mm depth of dentin was evaluated with micrometer in mesial and distal pulp horns. Pulp chambers were filled with 37.0$\pm$0.1$^{\circ}C$ water to CEJ. Chromium-alumina thermocouple was placed in pulp horn for evaluating of temperature changes. glass ionomer material was placed in 2mm. total curing time was 40s: continuous 40s, intermittent 20s, intermittent 10s. Glass ionomer material was cured with 300mW/$\textrm{cm}^2$, 550mW/$\textrm{cm}^2$ light curing unit. The results were as follows : 1. Temperature in pulp increased as curing unit power is increased. 2. Temperature in pulp more increased continuous emission than intermittent emission.

Character Design in Animation is usually used to get probability visually with unity between appearance and feature of character. Especially the horn of Japanese robot animation is not only the one of the feature of the genre but also shows difference between eastern and western culture. It is not difficult to find a case as the horned robot design, otherwise Nagai Go's comics like "Mazinger Z", "Getter Robo" "UFO Robot Grandiger" dedicated to set a horned design as a pattern. In the Nagai Go's work, horn is not only an ornament but also is used as a tool which reveals violent human nature.

Storytelling, a medium that arouses the customers' purchasing need by playing on their emotions, is the best content that can be used as it can increase the value of goods using information. This paper's significance is that it suggests cultural products that can be used by using Baeke relic Jinmyosu (Guard Animals) as a motif. The purpose was to present the possibility of high value-added cultural products using storytelling techniques. This study developed storytelling by adding the meaning of Jinmyo and Beoksa, who calm protected their masters from evil forces with horns and wings, and has the meaning of ascending into heaven and guiding the soul on the right path. That image gives a glimpse of originality and differentiation to Baekje. This study proposed 4 cultural products as 'Keeper Stone Mason' and 4 'Stone Mason Teller.' The proposed cultural products can help to give correct awareness of Baekje culture through a correct understanding of the historical significance of the Baeke relic, Jinmyosu. Moreover, it will help promote the originality and excellence of Baekje culture around the world by enhancing the value of Baekje culture. This study is expected to be used as a guideline for further research on developing cultural products that can create added value in various fields.

An abnormal shape of Bathyraja brachyurops was first reported from the catch of a bottom trawl in the southwest Atlantic Ocean in June 2022. Both pectoral fins of the specimen did not fuse with the head, resulting in a horn-like structure separated from the sides of the eyes. Analysis of mitochondrial DNA cytochrome c oxidase subunit I sequences showed that our specimen was perfectly matched to Bathyraja brachyurops registered with the National Center for Biotechnology Information. Our specimen possessed the following morphological features: a pair of flexible but elongated and pointed horns on the head; rough dorsal disc, densely covered with numerous small denticles on the head, anterior margin of pectoral fins and median line of the disc; a thorn between the first and second dorsal fins; and a pair of large ocelli at the base of pectoral fins. Unlike the normal B. brachyurops, our specimen had a slender clasper and no nuchal thorns, which may be related to the morphological abnormality. The horn-like structure on the head may be owing to the lack of fusion between the pectoral fins and head during early embryonic development.

Objective : Lumbar disc herniation can induce sciatica by mechanical compression and/or chemical irritation. The aim of this study was to compare the effects of GCSB-5 (Shinbaro$^{(R)}$) and NSAIDs on pain-related behavior and on the expressions of microglia, astrocytes, CGRP, TRPV1, IL-6, and CX3CL1 in a rat model of lumbar disc herniation. Methods : 112 male Sprague-Dawley rats underwent implantation of nucleus pulposus to a dorsal root ganglion (DRG). Rats were divided into five groups as follows; a saline group (the vehicle control group) (n=27), a 10 mg/kg aceclofenac group (the aceclofenac group) (n=22), and 100, 300 or 600 mg/kg GCSB-5 groups (the GCSB-5 100, 300, or 600 groups) (n=21 for each group). Rats were tested for mechanical allodynia at 3 days after surgery and at 1 day, 3 days, 7 days, 14 days, 21 days, 28 days, 35 days, 42 days, 49 days, and 56 days after treatment commencement. Immunohistochemical staining of microglia (Iba1), astrocytes (GFAP), CGRP, and TRPV1, and PCR for IL-6 and CX3CL1 were performed on spinal dorsal horns and DRGs at 56 days after medication commencement. Results : After 56 days of GCSB-5 300 administration, mechanical withdrawal thresholds were significantly increased (p<0.05), and immunohistochemical expressions of Iba1, GFAP, CGRP, and TRPV1 were reduced than other groups, but this difference was not statistically significant. Conclusion : These results indicate GCSB-5 reduces mechanical allodynia and downregulates neuroglial activity and the expressions of CGRP and TRPV1 in the spinal segments of a rat model of lumbar disc herniation.
