  • This study was carried out to investigate the morphological development of the tongue in the 60-, 90- and 120-day-old fetuses and neonates of Korean native goats by light microscopy. In 60-day-old fetuses, the tongue tissues were differentiated into epithelium, lamina propria, and muscle layer. The primordia of filiform, conical, lentiform, fungiform, and vallate papillae appeared by this time, and rudiments of taste buds were observed in the epithelia of the primordia gustatory papillae. The dorsal lingual epithelia were PAS positive. Collagenous fibers and blood vessels were present in the lamina propria. In 90-day-old fetuses, the gustatory glands were moderately positive for PAS and muscle fibers, and connective tissues were developed. In 120-day-old fetuses, many taste buds were observed in the gustatory papillae. The muscle bundles, collagenous fibers, blood vessels and gustatory glands were well developed. In neonates, over 40 taste buds were found in a transverse section of the vallate papillae. Muscle layers, blood vessels, collagenous fibers and gustatory glands were very well developed.

  • The skin of the eel goby, Odontamblyopus lacepedii, consists of epidermis, dermis and subcutis. The epidermis has three layers: the outermost layer, middle layer and stratum germinativum. The outermost layer is composed of polygonal cells or rather flattened cells, and mucous gland cells of acid mucopolysaccharides. The middle layer consists mainly of swollen small or voluminous epidermal cells and shows a web-shaped structure. The thickness of the epidermis depends on the various sizes and the number of layers of the swollen cells. Well-developed lymphatic spaces containing lymphocytes exist in the stratum germinativum and small scales are embedded in the dermis. A large number of blood capillaries are present just below the basement membrane, and a definite area giving AB and PAS positive was present between the basement membrane and scales, Taste buds ave distributed on surface of the epidermis at intervals. Considering the structural features of the skin, it may be considered that O. lacepedii is more likely to be related to cutaneous respiration as a dual respiratory system.

  • Histological observations of the barbels of torrent catfish (Amblycipitidae) in Korea are reported. The bullhead torrent catfish (Liobagrus andersoni) and Korean torrent catfish (L. obesus) have eight obvious barbels in two pairs each on the maxilla and mandible. Each barbel is composed of an epidermis, dermis, and central cartilagerod. The epidermis of the maxillary and mandibular barbels of the bullhead torrent catfish is thicker than that of the Korean torrent catfish (P<0.05) and is formed of stratified epithelium that contains many cutaneous taste buds and a few small club cells. There are many taste buds on the upper part of each barbel. The dermis consists of loose connective tissue fibers that enclose blood vessels and bundles of nerve fibers. The barbels of these fish can be categorized into stiff and flexible types and are accessory, feeding, and sensory structures. Our results validate the barbels as gustatory receptor organs for these fishes.

  • As people know how to brew a wine from fruits and cereals, they continued to develope various wines good to their taste. Korean wines are also ones made from cereals and they have long been eager to improve the delicate taste. They used to drink Takju, raw rice wine, made from nonglutinous rice and Nuruk, a kind of yeast starter. During Koryo Dynasty, Soju a liquor was imported from Won(the Chinese dynasty). Nowadays this traditional folk wine, which had been developed variously and drunk all over the country, is decreasing year after year. The purpose of this study was to review on the wines ; its kinds, raw materials, brewing method, manufacturing utensils, measuring units and devices and the terms for wine making based on 20 documents published in 1600, in the middle of Yi dynesty. The results of review were as follows. 1. There were 121 kinds of wines at that time in Korea. 2. Among the raw materials for wines, major materials were glutinous rice, nonglutinous rice, wheat flour, wheat, mung bean, and black soybean. And minor materials were pepper corn, Lycium chinenisis, cinnamon, pine needles, pine nuts, jujube, mugwort leaves, lotus leaves, pine corn, pine bud, chrysanthemum, pine flowers, honey, Acanthopanox seoultenses, bamboo-root, marrowbone of blak cow, sweet flag, Ciprus noblis, Saurea lappa, honey suckle, Tricho santhes, azalea, the leaves of the paper mulberry, and bark of chungum tree. 3. There were several kinds of wines such as a wine without using Nuruk, a wine made from glutinous rice, nonglutinous rice, or glutinous and nonglutinous rice with flour. 4. There were several brewing methods for wines such as a wine boiled with ring rice cake, a wine brewed with loaves of rice cake, a wine brewed with hard boiled rice, a wine brewed with rice gruel, and a wine brewed with powdered rice gruel. 5. There were 23 kinds of utensils including measuring devices for weight and volume.

  • Objectives Children's unique taste bud often gives them difficult time to take oriental medicines. To overcome, survey was conducted focusing on useful and practical tips on how to take them. Methods The survey was carried out by posting mail questionnaire. Target clinics for the survey were selected by the internet search engine, Google, Daum, and Naver, and typing in "oriental treatment + pediatrics", "pediatrics + oriental medicine", "pediatric oriental clinic". 24 clinics were searched, but they were further narrowed down to the specialized pediatric oriental clinics. Also, total of 38 inquiry leaflets were distributed to 14 University Oriental Hospitals. Results If children refuse to take the medicine, mixture with sweeteners can be prescribed for them. Among them, oligosaccharide is the most recommended followed by sugar and honey. To avoid rejection to medication, use of different formulation, such as distillation medicine, soft X-Section, granulated medicine, and character printing can be used. Conclusions The most effective method is to investigate the mixture first, and then the alternative formulations.

  • Fragaria ${\times}$ ananassa (Duch.) cultivars, 'Wongyo 3 115' a nd 'Wongyo 3 116', we re bre d as a n inte rme diate parent l ine using heterosis of $F_1$ hybrids in octoploid strawberry. These two new cultivars were developed as inbred lines ($S_9$ generation) propagated from both seed and runners/stolons. 'Wongyo 3115', an inbred line derived from the 'Benihoppe' cultivar, has a semi-upright plant shape showing a vigorless growth habit, weaker than the original 'Benihoppe' cultivar; it has early flower bud differentiation and produces 10 flowers per cluster when grown from healthy seed. 'Wongyo 3115' has low yields of conical type fruit with pink colored skin; average fruit weight is approximately 11 g. The important characteristic of 'Wongyo 3115' is its excellent fruit firmness, firmer than the original variety. 'Wongyo 3116', an inbred line derived from the 'Doyonoka' cultivar, has an upright plant shape, vigorless growth habit, weaker than that of the original 'Doyonoka' cultivar; it has early flower bud differentiation and produces 8 flowers per cluster when grown from healthy seed. 'Wongyo 3 116' has oblate type fruits with red skin and an ave rage weight of approximately 12 g. The important characteristics of 'Wongyo 3116' are excellent fruit shape and higher yield than other inbred lines, although it produces small fruits compared to the original cultivar. Both cultivars have excellent taste, high sugar/acid ratio, and good texture. In regards to disease and pest resistance, 'Wongyo 3115' and 'Wongyo 3116' have a tendency to be sensitive to powdery mildew, anthracnose and the two-spotted spider mite.

  • The morphological development of lingual papillae in fetuses between 60, 90, 120 days gestation and neonates of Korean native goat were investigated by scanning electron microscopy. In 60 day old fetuses, the primordia of lingual papillae were observed on the dorsal surface epithelium and those of papillae were primordial fungiform, vallate and conical papillae. The many of microridges and microplicae were observed on the surface of those epithelial cells. In 90 day old fetuses, the rudiment of lentiform and filiform papillae were appeared. There were microplicaes on the surface of the conical papillae epithelium. In the 120 day old fetuses, the lingual papillaes were well developed. The taste bud were opened on the top of vallate papillae that were compactly many of short microvilli. Moreover, secondary papillae partially were observed on top of vallate papillae. In neonate, the fungiform, vallate and lentiform papillae were similar to the adult lingual papillae, but filiform and conical papillae were different from the mature lingual papillae. The outline of filiform papillae were irregularly in indented, but those of conical papillae were regularly. The diameters of filiform, fungiform, conical, vallate and lentiform papillae were about 80~100, 190~250, 230~470, 360~670 and $730{\sim}1,140{\mu}m$, respectively. The height of filiform and conical papillae were about $130{\sim}140{\mu}m$ and $145{\sim}250{\mu}m$.

  • The flat-headed goby, Luciogobius guttatus, inhabits tidepools and river mouths, and stays under stones on the dried bottom for the duration of the low tide. To know the relationship of its respiration and habit in this fish, the epidermis of five appendages was observed. The epidermis has three layers: the outermost layer, middle layer and stratum germinativum. The outermost layer is composed of polygonal cells or rather flattened cells, and mucous cells. The unicellular mucous cells showing acid mucopolysaccharides are 11.1 to $16.1{\mu}m$ in mean height and in one or two rows. The middle layer consists mainly of large epidermal cells that are swollen by adjacent epidermal cells and arranged in a web-shaped structure. The swollen cells are 12.3 to $15.2{\mu}m$ in mean height and arranged in one to 11 layers. Since the swollen cells occupy the entire height of the epidermis, the epidermis is thick. A large number of blood capillaries are present just below the stratum germinativum. Taste buds are distributed at intervals on the surface of the epidermis. Based on these epidermal strucures, it is likely that L. guttatus utilizes cutaneous respiration in a dual respiratory systems.

  • A new cultivar 'Daewang' strawberry was developed by the National Institute of Horticultural & Herbal Science for forcing culture in 2010. The cultivar 'Daewang' was originated from the cross between 'Maehyang', a high firmness cultivar and 'Wongyo 3111', a high sugar content in 2006. The cultivar shows erect plant type, vigorous growth habit, early flower bud differentiation with 12-15 flowers per cluster from planting on healthy nursery. Fruits of 'Daewang' are conical type having a bright red skin color, and 16-17 g in an average weight. 'Daewang' is suitable for forcing culture as time required for dormancy breaking ranged between 50 and 100 hours. This cultivar has excellent taste for high sugar/acid ratio as sugar content of $11.1^{\circ}Brix$, acidity of 0.39% with abundant texture and can be harvested by late spring because the fruit firmness of 'Daewang' was $18.2g{\cdot}mm^{-2}$ that was about $7.9g{\cdot}mm^{-2}$ higher than $10.3g{\cdot}mm^{-2}$ of 'Akihime' cultivar. But although total yield is not significantly different from 'Akihime' cultivar, its marketable yield is remarkably higher than that of 'Akihime' cultivar. Disease and pest resistance of 'Daewang' have a tendency to sensitive powdery mildew, anthracnose and spotted spider.
