To determine the medicinal properties of Pleurotus cornucopiae and Safflower Oil (PS), the osteoblast effect was investigated. PS can prevent estrogen deficiency-induced bone loss. It was taken the measurements of biochemical factors such as serum osteocalcin, alkaline phosphatase, IGF-1, and bone status. Forty adult female Sprague-Dawley rats were randomly assigned to four equal groups for 12 weeks of treatment: (1) sham operation (SHAM) + vehicle; (2) ovariectomy (OVX) + vehicle; (3) OVX + 17β-estradiol (25 μg/kg); (4) OVX + PS (300 mg/kg/d, PO). At the end of the experiment, bone turnover, and trabecular microarchitecture were assessed by micro-computed tomography (micro-CT), and histopathology, respectively. Ovariectomized rats experienced remarkable increases in global volumetric bone density, and trabecular microarchitecture deterioration. These OVX-induced pathological changes are reversible in that most of them could be mostly corrected upon 17β-estradiol treatment. PNS treatment significantly prevented bone mass loss and microarchitecture deterioration. Moreover, PS enhanced osteoblast activity but suppressed osteoclast turnover, as evidenced by decreased levels of serum C-terminal telopeptides of type I collagen and elevated levels of alkaline phosphatase. PS mitigates estrogen deficiency-induced deterioration of trabecular microarchitecture.

In this research, we have calculated characteristics of wave-piercing high-speed planing hull, by using a RANS solver and overset grid method, for comparing with experimental measurements of that and simulating with several appendages, since the computed results of commercial CFD code look reasonable for the prediction of the performances of planing hulls on calm water in planing conditions. As a result, it is confirmed that the dynamic instability phenomena in pitch and heave motions (porpoising) occurred after a certain FnV, and effectively suppressed using some of appendages, especially the 0.5L spray rail is suppressed to 24-55 % in the pitch motion and 33-55 % in the heave motion. In spray phenomenon, 1L hard chine suppress spray effectively and it is effective to set the angle of appendages to be less than 0° in order to suppress wave.

The purpose of this research aims to reveal how radish kimchi (Jong-ga) differs in Jong-ga recipes and old cookbooks. To accomplish this, old cookbooks ( Soowoonjabbang , Jusiksiui , Eumsikbangmunnira , Siuejunsuh , Banchandeungsok , and Buinpilji ) were reviewed and 8 Jong-ga recipes (Seogye Park Se-dang from the Bannam Park clan Jong-ga, Myungsukgong from the Changnyeong Jo clan Jong-ga, Nampa Park Jae-gyu from the Milyang Park clan Jong-ga, Geunggudang Kim Joong-jeung from the Gwangsan Kim clan Jong-ga, Dongchundang Song Jun-gil from the Eunjin Song clan Jong-ga, Myeongjae Yun Jung from the Papyung Yun clan Jong-ga, Daeseunggong Ryu Cha-dal from the Munhwa Ryu clan Jong-ga, Inmukjae Son Sung-jeung from the Milseong Son clan Jong-ga) from five areas were reviewed. We classified the radish kimchi into five categories, radish kimchi, Dongchimi, kkakdugi, Seokbakji and Nabak kimchi and other kimchi. According to old cookbooks, most kimchi was made with radish, cabbage, cucumber, pear, yuju, fish meat, and salt. Modern Jong-ga is made of seasoned radish, sticky rice paste, seafood, sugar, powdered pepper, fish sauce and salt. This study helps to understand notable clans’ cultures via their recipes for kimchi.

식물추출물로부터 보다 안전하고 효과있는 새로운 tyrosinase 저해제를 개발하기 위한 연구의 일환으로 먼저 기존의 spectrophotometric assay를 개선한 새로운 TLC 검색방법을 사용하여 여러 식물추출물을 검색한 결과 백자인의 메탄올추출물이 강한 tyrosinase 저해활성을 갖고 있음을 알 수 있었다. 따라서 백자인의 메탄올추출물로부터 tyrosinase 저해제를 분리하기 위하여 먼저 탈지 메탄올추출물을 에테르, 에틸아세테이트
