This study was carried out to determine the effect of the duration of chilling treatment and the lifting time of bulbs on growth of Lilium Oriental hybrids for product of cut flower in the type of forcing or semiforcing culture in Korea. "Casablanca", "Acapulco" and "Le Reve" in lilium Oriental hybrids were used in these experiment and carried out from 1999 to 2000 in Iksan, Korea. The bulbs for experiment were lifted on August 27, September 27 and October 27 and the all of them were chilled at 5±1℃ for 0,8,10,12 weeks. Development of the bulbs lifted on October 27 was superior than that of lifted bulbs on August 27 in the three cultivars. The bulbs lilted lately and chilled for a long time were sprouted more earlier and grown faster. In order to increase bulb sprouting until 100%, the duration of chilling treatment of bulbs was need for 12 weeks on August 27, 10 weeks on September 27 and above 8 weeks on October 27. The flowering according to the duration of chilling treatment and the lifting time of bulbs was same above. Consequently, the bulbs should be chilled at 5±1℃ for chilled for 10 weeks at late September and 8 weeks in producted bulbs at late October in earlyㆍMidseason variety fur product of cut flower hut bulbs of late variety should be chilled for 12 weeks at late September and 10 weeks at late October.

정보통신의 발전은 경제 구조에 많은 변화를 가져왔으며, 향후에도 많은 변화를 예고하고 있다. 가장 대표적인 것은 경제 흐름의 근간이라 할 수 있는 유통의 변화이다. 이것은 통신망 위에 구축되는 가상의 공간에서 이루어지는 유통을 지칭하는 것으로, 빠른 속도로 발전하고 있다. 이러한 빠른 발전에도 상품데이터베이스를 구성하는 것에는 매우 불합리한 비효율성이 존재한다. 상품데이터베이스 구성의 가장 큰 비효율은 싸이트들이 개별의 데이터베이스를 구성한다는 것이다. 이런 문제를 해결하기 위해 시멘틱웹의 RDF(Resource Description Framework)언어를 이용하여 웹 온톨로지를 구성하여 공급자와 판매자간 상품 데이터를 공유하게 된다면, 전자상거래에서 상품데이터베이스 구성의 비효율성을 제거 할 수 있다. 따라서 본 논문에서는 RDF의 소개와 RDF 웹 온톨로지 편집기를 제작하고, 구성된 RDF를 참조하여 간단한 쇼핑몰을 구성하여 온톨로지를 통한 데이터의 효율적 상호운영성(Interoperability)을 증명하여, 현재 제안되고 있는 상품 카탈로그 분야의 발전에 기여하고자 한다. IT development has brought about many changes in an economic structure, and will bring about many changes in the future. The most representative thing is the change of distribution which is a basis of the economic flow. It means a distribution an a virtual space built through communication network. It has rapidly developed. However, building the product database by each site for numberless products is very unreasonable simple repeating process. To solve this problem, if the product data is shared between a supplier and seller through the web ontology by using the Semantic Web RDF (Resource Description Framework) language, an efficiency of e-commerce will be created. Accordingly, the study is intended to prove an efficient interoperability of data through ontology by introducing the RDF, fabricating the RDF web ontology editor, and building a simple shopping mall through organized RDF, and to contribute to a development of currently-proposed product catalog field.

Properties analyses and treatment characteristics of waste slurry discharged in the wetted flue gas desulfurization process using Mg(OH)₂as a absorbent were investigated. Aeration and coagulation test were carried out to evaluate variation of some factors such as COD, SS, T-N, etc. related to waste slurry treatment. The hydraulic retention time(HRT) and coagulant dosage rate were applied as operating variables in experiment. As experimental results, the reduction effects of COD, SS in aeration test were distinct, due to oxidation of SO₃ and floc, formation of suspended solids. It was also found that the reduction efficiencies of SS and T-P in coagulation test are higher than 90%.

The dosimetric system consisting of parallel plate type of air-filled ionization chamber and charge-to-voltage converter was designed to do daily constancy check of the high energy photon beam of Clinac 1800C linear accelerator(Varian Co., Pola Alto, California, USA). The ionization chamber was fabricated using acrylic plate for the chamber medium and printed circuit board for electrical configuration. The sensitive volume of the chamber was 1.6cc. High voltage generator was fabricated using the conventional 9V batteries to apply the high voltage(300V) to the electrode of the ionization chamber. Also the charge-to-voltage converter was designed to collect the electrons produced in the ionization chamber cavity. The output reading was converted into the digital signal using the commercially available digital multimeter to produce four-digit readings. The major parameters of the chamber characteristics such as reproducibility. linearity. leakage current. zero drift. timer error. dose-rate effect and polarity effect etc. were measured. These data were comparable to those of the QA-purpose dosimetric system commercially available in the market. Also this dosimetric system can be extended to do the flatness/symmetry check of the photon as well as the constancy check of the various electron beams for the purpose of outputs as well as energy measurements.

Exercise-induced increase of BDNF decreased TG and glucose in obese adolescents

( Yeong Geun Kim ),( Hyun Jun Kim ) 한국운동영양학회 2013 Physical Activity and Nutrition (Phys Act Nutr) Vol.17 No.3

e purpose of this study is to investigate the effects of exercise on body composition, blood lipids, BDNF, FGF and IGF-1in obese adolescents. The subjects of this study were 16 boys, who were divided into combined exercise group (EG, n = 8) and control group (CG, n = 8). The exercise program was conducted for 50-60 minutes per day, four times a week, for a 12-week period. We measured body composition (Weight, body fat mass, body fat percentage and lean body mass), lipid (TC, TG, Glucose, HDL-C,LDL-C), BDNF, FGF and IGF-1. The comparisons of mean differences before and after the intervention between group, weight (p < .05), BMI (p < .05), Glucose (p < .05) of EG decreased more significantly than CG. And the BDNF (p < .05) was more significant increased than CG. FGF and IGF-1 of EG increased more than CG. The change in BDNF after 12 weeks of exercise program had a reverse correlation with TG (r = -.770, p < .001) and Glucose (r = -.537, p < .05). The IGF-1 change at 12 weeks of exercise program is found to have a reverse correlation with percentage of body fat (r = -.525, p < .05), TC (r = -.520, p < .05), and Glucose (r = -.612, p < .05). It was found that increased BDNF after exercising influences the decrease in TG and Glucose. It is probably because increased BDNF after exercising oxidizes the glucose and TG to increase body temperature and oxygen and energy consumption. These data indicate that 12 weeks of exercise program decreased BMI and increased concentrations of BDNF in the serum.

Kim, Je-Won,Son, Chang-Sik,Jang, Yeong-Geun,Choe, In-Hun,Park, Yeong-Gyun,Kim, Yong-Tae,Ambacher, O.,Ctutzmann, M. Materials Research Society of Korea 1999 한국재료학회지 Vol.9 No.1

The room temperature optical transmission spectra of GaN /InGaN/GaN single quantum wells (SQW) and InGaN/GaN heterostructures grwon by low pressure metalorganic chemical vapor deposition have been measured. The dependence of the absorption edges of the GaN/InGaN/GaN SQW on the well width has been determined from the transmission spectra. The result shows that the absorption edge of GaN/InGaN/GaN SQW shifts towards lower energy as increasing the well width. The dependence of the absorption edges of the InGaN/GaN heterostructures on InN mole fraction has also been determined from the transmission spectra. The result is compared with calculated values obtained from Vegards's laws. Our result shows a good agreement with the calculated values.

Kim, Yeong Eun,Ryu, Jina,Kim, Jun Tae,Suh, Seokjin,Hong, Geun-Pyo,Ko, Sanghoon 한국식품과학회 2018 Food Science and Biotechnology Vol.27 No.2

The aims of the present study were to prepare different-sized red ginseng powders and investigate the particle size effect on the release property of ginsenosides in in vitro digestion conditions. Ultrafine powder showed bimodal particle size distribution with a large peak at around $100{\mu}m$ and small peak at around $10{\mu}m$, differently from fine powder showing unimodal distribution at $100{\mu}m$. The specific surface areas of fine- and ultrafine powders were $48.72{\pm}6.41$ and $86.74{\pm}5.96m^2/g$, respectively. Time-dependent release property of the powders in the simulated gastrointestinal fluids was determined by quantifying ginsenoside Rg1 released. The initial and final concentrations of ginsenoside Rg1 released was higher in ultrafine powder than fine one. It is expected that particle size reduction and corresponding increase in the specific surface area have a potential to improve the release of ginsenosides in the gastrointestinal tract and enhance the chances to be absorbed in human body.

Kim, Hong-Kook,Choe, Yeong-Ho,Kim, Geun-Seop,Kim, Ha-Young,Kim, Byeong-Soo The Korean Society of Veterinary Service 2018 韓國家畜衛生學會誌 Vol.41 No.3

Red ginseng marc is a by-product of Korean red ginseng (panax ginseng CA Meyer) and contains ginsenoside which has pharmacological effects. The Korean red ginseng marc was fermented with Bacillus subtilis (RGMB). This study was carried out to investigate the RGMB effect on swine immunity. The variation of ginsenoside depending on the RGMB fermentation time was analyzed. Swine (Landrace${\times}$Yorkshire) were divided into control group (basic diet) and RGMB group (RGMB 1% diet). One percent RGMB was fed to the RGMB group for 28 days. The biochemical parameters, cytokine and immunoglobulin were analyzed. For 48 hours of fermentation on RGMB, ginsenoside Rb1 had increased 180.94%, Rg3 235.85%. Rg1 wasn't detected before fermentation, but was detected after 48 hours of fermentation. The RGMB had effect of deceasing initial AST concentration $79.33{\pm}12.85U/L$ to $54.00{\pm}14.46U/L$ in final and was significantly lower (P<0.05) than control in final. In final RGMB had significantly lower (P<0.05) ALT concentration of $48.57{\pm}8.26U/L$ comparing with control group of $65.43{\pm}10.31U/L$. RGMB had the effect of significantly decreasing (P<0.05) $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration of $2.44{\pm}1.31ng/mL$, $0.71{\pm}0.36ng/mL$ and $0.51{\pm}0.21ng/mL$. The IgA concentration had significantly increased (P<0.05) in RGMB group of $0.56{\pm}0.06mg/mL$ in final. These results demonstrate that RGMB has effect of increasing immunity and practicable to use as feed additives on swine.
