Yacht is operated by wind-driven thrust on the saii, but also experiencing the side force. Thus the keel attached on the bottom of main hull prevents it from flowing sideway. Since the keel affects the stability and thrust of yacht, its selection is one of the most important factor in design. In the present paper the correlation between yacht hull and keel was investigated. through comparison of forces measured at various combinations of heeling and leeway angles with and without keel. Keel-only test was also performed to find out the drag and lift characteristics of keel itself. finally three different types of keel, i.e. fin keel, bulb keel and winglet keel were tested to compare their advantages and drawbacks.

골판지조합은 지난 7월13일 농산물품질관리원장에게 "농산물포장용 골판지상자 중량 허용오차 기준 제안"을 하였다. 이번 제안은 농림수산식품부 산하 농산물품질관리원원에서 운영하고 있는 농산물포장 표준규격에서 중량 표시규격은 있으나, 이에 대한 허용오차에 대한 명확한 기준이 없어 실제 거래관계에서 혼선이 야기되고 있으며, 골판지포장은 수분함량 및 평량 허용오차 등으로 인해 동일한 원지배합이라 할지라도 다소의 중량차이가 발생할 수 있고, 또한 KS 표준규격상 라이너, 골심지에 대한 평량 허용차가 ${\pm}4%$, 외부포장용골판지의 수분함량 허용오차가 $10{\pm}2%$임을 감안해서, 현재 명확치 않은 중량 허용오차 기준을 ${\pm}5%$로 개정하는 것이 상당하다는 판단을 골판지포장기업 35개사를 대상으로 설문조사한 자료를 바탕으로 보고서를 작성하여 함께 제출하였다.

Objectives: This experimental study has been done to compare the Os Draconis composition before and after using processing method. Os Draconis has a quality for calming the liver meridian function and relaxation the mind. Methods: I studied the Os Draconis and processed Os Draconis by vinegar to compare the compositions and its' character. Results: Os Draconis is not a dinosaur's bone fossil but a mammal's bone fossil which has a Calcite mineral, an Apatite mineral, $SiO_2\;Al_2$ O, etc. Os Draconis contains a main ingredients CaO>50.00%. Processed Os Draconis which is heated and soaked in vinegar changes to weak condition Conclusion: Os Draconis is supposed to be a mammal's bone fossil. Some Os Draconis has a radioactive substance like a U, Th so we pay heed to deal with it in a medical clinic.

A new novel Whipping Factor is proposed as a measure of the ship damage potential due to an underwater explosion bubble pulse. The factor was derived from the relationships among the charge weight, its depth and the fluid acceleration due to pulsating gas bubble. From the whipping response analyses for three uniform Timoshenko beams with similar characteristics of real naval surface ships, we have confirmed the maximum bending moment responses of beams due to whipping are almost same if the applied whipping factor is constant regardless of the charge weights and depths, which could validate the proposed whipping factor.

Objective: The aim of this study was to evaluate the effects of Gyejigamchoyonggolmoryeo-tang on facial flush. Methods: Facial flushwas evaluated using photographs and questionnaires. The (VAS) and investigator's global assessment were used to measure the improvement in facial flush symptoms. Results: The visual findings were. The VAS score decreased from 10 to 0 after administration of Gyejigamchoyonggolmoryeo-tang for 40 days. In addition, accompanying symptoms such as neck pain, palpitation, and insomnia were improved. These results indicated that Gyejigamchoyonggolmoryeo-tang was effective for emotional facial flush. Conclusions: This study shows the effective treatment of facial flush using Gyejigamchoyonggolmoryeo-tang based on the provisions of the Shanghanlun disease pattern identification diagnostic system.

Body scales directly exposed to external environments can be an important factor to understand various characteristics of a species such as habitat features, life history and basic ecology. In this study, we compared size and morphology of dorsal, outermost dorsal, keeled dorsal and ventral scales of total nine snake species in Korea; Oocatochus rufodorsatus, Elaphe dione, Rhabdophis tigrinus, Amphiesma vibakari, Dinodon rufozonatum, Hierophis spinalis in the Colubridae and Gloydius ussuriensis, G. brevicaudus, G. saxatilis in the Viperidae. The morphological characteristics of the scales seem to well reflect foraging modes and moving activity of both families. Uniquely D. rufozonatum had a diamond shape dorsal scale and had the greatest and smallest value of the ratio of width/length of dorsal and ventral scales, respectively. O. rufodorsatus, D. rufozonatum and H. spinalis did not have keeled dorsal scales and E. dione had keel on the few of dorsal scales. In addition, morphological characteristics of scales of three viper species were closely consistent with previously known phylogenetic relationships.

Morphological characters of inflorescence, spikelet, rachilla, glume, lemma and palea about 17 taxa of Korean Poa L. were investigated to evaluate their taxonomic significances. The bulbil present or not, inflorescence shape, callus shape of lemma and surface shape of palea were thought to be the subgenus characters. The keels shapes of palea, the number of lower glume, lateral nerve shape of lemma were thought to be the section characters. The number of floret, rachilla present or not, the number of lower glume, nerve shape of glume, surface shape of lemma were thought to be the species characters. Consequently, 17 taxa of the Korean Poa L. is classified into 3 subgenus (Ochlopoa, Stenopoa, Stenopoa), 7 section(Arenariae, Ochlopoa, Homalopoa, Poa, Pandemos, Tichopoa, Stenopoa). 6 taxa, P. ullungdoensis, P. takeshimana and P. matsumurae, P. nipponica, P. radula, P. viridula, not included in the existing classification system, were suggested to their taxonomic category in infragenic rank, and P. nemoralis, had been included in section Stenopoa of subgenus Stenopoa, was proposed to move to section Poa of subgenus Poa. P. ullungdoensis, reported as new species in 1955, was grasped its taxonomic identity.

The osteological characters of Aphyocypris chinensis of subfamily Leuciscinae were examined and the systematic position of this species is discussed through comparison with other species of subfamilies Leucisicinae and Cultrinae. Numbers of the dorsal an danal fin ray, having no symphyseal knob and barbels and separation between dermosphenotic and supraorbital, are in acord with those of subfamily Leuciscine, and the abdominal keel and trigemino-facial nerve foramen of the prootic are more closely related with those of subfamily Cultrinae. But several diagnostic characters detected only in this species are as follows ; 4 infraorbitals, the shape of ethmoid, 5-6 hypurals, the broad orbital width, having no extrascapular, incomplete lateral line and considerable small size.

This study was done to investigate the effect of SHCG on hypertension in spontaneous hypertensive rats. SHR was sensitized and challenged with Sihogayonggolmoryeotanghabcheongsimyeonjaemgagambang (SHCG) for 4 weeks. The 3 groups have 6 rats, respectively. Experimental group was treated with 56.7 mg/kg of SHCG orally and control group was treated with 56.7 mg/kg of normal saline instead. SHCG significantly showed safety against cytotoxicity on hFCs and toxicity in the liver. SHCG significantly decreased the blood pressure and the heart rate. SHCG significantly decreased the levels of aldosterone. SHCG significantly decreased the levels of dopamine, norepinephrine, and epinephrine. SHCG significantly decreased the levels of potassium and chloride. SHCG significantly decreased the levels of uric acid and creatinine. These results suggest that SHCG might be hopeful in treatment of hypertension.
