There are futures, options as derivatives in our capital-market including KOSPI200 futures and options. Unfortunately linked-manipulations between stock tradings and derivatives tradings happen too often. It is able to distinguish linked-manipulations from faked-normal stock tradings using some criterias ; real purposes of tradings, rationals manners or not, the scales of profits. These acts of unfair trades are increasing in our capital market and especially the occurrences of new type of unfair trades cast attentions on same fields for example manipulations disguising hedge in option trades etc. Crimes in manipulations fields are developing without halts. In order to cope with its revolutions, we should make clear standards to distinguish linked-manipulations from faked-normal stock-tradings by searching same case studies.

In this study, agronomic characteristics and fatty acid composition of 121 flax (Linum usitatissimum L.) germplasms were analyzed. The flax germplasms had a fairly short growth period of 75-95 days. The plant height at maturity varied from 52 to 124 cm. The flower color varied from white to lilac and even purple. Early flowering flax germplasms had white flowers and were resistant to lodging. In early flowering flax germplasms, all agronomic characteristics, including growth period, plant height, branch number per plant, stem diameter, number of capsules per raceme, seed number per capsule, 1000-seed weight, and seed yield, were decreased. The average fatty acid composition of 121 flax germplasms comprised palmitic acid (5.3%), stearic acid (4.3%), oleic acid (29.7%), linoleic acid (13.1%) and linolenic acid (46.4%). The total content of unsaturated fatty acids ranged from 84~94% with an average of 88%. Among the fatty acids, linolenic acid (omega-3) content was the highest with a range of 36~54%. In five selected flax germplasms (Hollandia 1803, Red son, C & F Res Br 1767, Wiera, and Ireland 1657) with high linolenic acid (≥51%), total lipid and protein contents were 30~36% and 5.4~6.9%, respectively. Overall, flax can practically be adoptable into cropping systems in South Korea and utilized as a scenery crop, since flax has a short cultivation period with diverse flower colors.

Ninety ducks (one-day-old Pekins, 45 males and 45 females) were used to evaluate the effects of supplementing diets with Houttuynia cordata powder on the fatty acid profiles of duck breast meat. The ducks were allotted to one of the three treatment diets using a completely randomized design, each treatment-group containing three replicate pens with ten birds each (five of each gender). The experimental diets were: 1) Control (basal diet), 2) T1 (Control+ 1% Houttuynia cordata) and 3) T2 (Control+2% Houttuynia cordata). In spite of significant difference, the addition of Houttuynia cordata resulted in higher unsaturated fatty acid and lower saturated fatty acid contents than in the Control group. However, no remarkable difference was observed between 1% and 2 % Houttuynia cordata groups for fatty acid profiles.

Regional air quality regulation is a system that allows the Minister of Environment to designate the local area as air quality control region where the concentrations of air pollutants are exceeding the environmental standards, and the local governments that administrate the regulated area have to develop and practise a plan for reducing the air pollutants. From the data observed yearly by the monitoring stations in 8 provincial cities with more than 0.5 million people was judged the compliance with air quality standards in each municipality for the period of 2003 to 2013. As the result of investigation on air pollutants concentrations of each city, it was found that there was no station that exceeds the ambient air quality standards of CO, SO2 and 24-hour NO2. But all municipalities exceeded the standards of 8-hour O3, annual and 24-hour PM10, and therefore 8 municipalities can be designated to be under the local air regulation. For the annual NO2 were the monitoring sites necessary requirements for designation of the air quality regulation region in Cheongju, Cheonan, Daejeon and Gwangju area. Incase of 1-hour O3, some of stations in Pohang, Cheongju, Cheonan and Changwon area were over the designation standards for the air quality control region.

일본 외무성 홈페이지를 살펴보면 독도의 옛 이름 송도(松島)가 왜 울릉도의 옛 이름 죽도(竹島)로 부르게 되었는지를 자세히 설명하고 있는데 이 논리에는 무주지 선점 법리가 이용되고 있다. 1876년 블라디보스토크 영사관을 통해 제출된 ‘송도개척건의(松島開拓之 議)’의 송도(松島)는 ‘일본 땅’ 송도(松島)라는 이름을 차용한 것으로 이를 적용해 해군성은 울릉도를 송도(松島)로 명기하였다. 당시 해군성은 울릉도에 소속 불명확한 1도 2명의 이름을 붙여 조선의 범위에서 제외시키고 군함으로 민간인들을 실어 날랐다. 그리고 1881년 조선정부에 발각되자 일본 외무성은 1880년까지 명칭 혼란이 발생하는 과정에서 민간인이 침입했다고 변명하였다. 이러한 수법은 일본의 영토 침탈 수법으로 독도의 편입과정도 이와 동일하다. 1900년 러시아가 울릉도를 점거하자 일본은 일본어민이 어로 활동 중 ‘발견’했다고 유포하면서 관 주도하에 계획적으로 ‘발견’한 독도를 선점하였고 민간인을 동원한 영토 편입은 ‘영유 의사의 재확인’이라고 주장하고 있다. 자료 조작과 왜곡을 일삼는 일본은 국제법상의 무주지 선점 법리로 자신들의 침탈을 정당화하고 있지만 1875년 블라디보스토크 영사 세와키 히사토 ｢블리디보스토크 견문록｣에는 이러한 일본의 영토 침략 사실을 여실히 증명하고 있었다.

2005년 유기성폐기물의 직매립이 금지되었다. 또한 유기성폐기물의 해양배출 기준 강화에 따라 2013년부터 음식물류폐기물의 해양배출이 금지되었다. 국내 2013년 음식물류폐기물 발생량은 전체 생활폐기물 중 26.0%인 12,501 톤/일 규모로 배출되고 있으며, 처리량은 2012년 대비 약 58.4%로 매년 급증하고 있다. 최근 음식물류폐기물의 처리방안으로 바이오가스화가 주목받고 있다. 정부는 “폐자원 및 바이오매스 에너지대책 실행계획”(환경부 2009) 등을 바탕으로 바이오가스화 시설의 신규 설치 및 운영을 추진하고 있다. 바이오가스화 시설의 신규 건설이 본격적으로 이루어지는 반면, 운전 효율성은 운전 및 유지관리 미숙, 계절별 영향 등으로 인하여 처리기준에 미치지 못하는 시설이 다수인 실정이다. 본 연구에서는 실제 운영 중인 A지역의 음식물류폐기물 바이오가스화 시설을 대상으로 계절별 산발효조의 정밀모니터링 및 시설 운영인자를 조사･분석하여 계절별 산발효조 상태에 따른 혐기소화조의 운전효율성을 평가하고자 하였다. 산발효조의 현황을 파악하기 위하여 봄, 여름, 가을에 걸쳐 휘발성지방산, 영양물질, CODcr 등의 정밀모니터링을 실시하였다. 또한 해당 시설의 바이오가스 생산량, 휘발성지방산 등과 같은 운영 자료는 2014년 3월부터 2015년 4월까지 약 1년 동안의 데이터를 바탕으로 월별 평균 값을 도출하였다. 분석결과와 운영 자료를 비교·분석한 결과, 여름철 온도의 상승의 영향으로 산발효조 내부에서 음식물류폐기물이 더욱 활발히 분해되어 휘발성지방산의 농도가 증가하였다. 이에 따라 여름철 산발효조의 영향으로 메탄생성율 및 바이오가스의 메탄 함량(%)이 저하되는 경향을 보였다. 특히 메탄생성율은 여름철(6~8월) 30.0~41.03 m³ CH4/tonFWL, 여름을 제외한 다른 계절의 경우 38.6~51.6 m³ CH4/tonFWL로 계절에 따른 차이를 나타내었다.

Nonalcoholic fatty liver disease (NAFLD) is a kind of liver inflammation caused by an accumulation of fat in the liver. Patients with NAFLD have an increased risk to develop liver fibrosis, which leads to cirrhosis. To investigate hepatoprotective effects of Agrimonia eupatoria L (A. eupatoria), oleic acid-induced NAFLD in HepG2 cells was used and A. eupatoria was fractionated with ethanol (EtOH), n-hexane, dichloromethane (CH2Cl2), ethyl acetate (EtOAc), n-butanol (BuOH), and H2O. Cells treated with the EtOAc fraction showed the highest lipid accumulation inhibiting effect. A. eupatoria also suppressed triglyceride accumulation and inhibited expression of lipid marker gene, such as a peroxisome proliferator activated receptor γ (PPAR-γ). Moreover, another marker, mRNA expression level of peroxisome proliferator activated receptor α (PPAR-α) was significantly increased by in a dose-dependent manner. These results suggest that A. eupatoria is a potent agent for the treatment of NAFLD.

In the present study, we investigated the effect of 70% EtOH extract from Hippophae Rhamnoides L. leaves (HRL) on the anti-obesity effect in 3T3-L1 cells. The effects of HRL on lipid accumulation in 3T3-L1 cells were examined using Oil Red O staining. In addition, we examined the gene expression levels by using RT-PCR and western blot. The results of this analysis showed that 100 ㎍/㎖ HRL significantly increased the inhibition of lipid accumulation by 82.25%; significantly decreased the mRNA expression of sterol regulatory element binding protein-1c (SREBP-1c), peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer binding proteins α (C/EBPα), and fatty acid synthase (FAS) in 3T3-L1 cells as well as the stimulated protein expression of AMP-activated protein kinase (AMPK); and suppressed the expression level of PPARγ. These results suggest that HRL can prevent adipogenesis through activation of AMPKα and inhibition of adipogenesis transcription factors.

본 연구에서는 연화 열수 및 에탄올 추출물의 3T3-L1 지방세포 분화 및 ROS생성 저감효과를 구명하기 위하여 3T3-L1 전지방세포 분화과정 중 연화 열수 및 에탄올 추출 물에 의한 지방축적과 ROS 생성을 관찰하였다. 연화 열수 및 에탄올 추출물은 XTT assay에서 100, 200 및 400 μg/mL 농도에서 세포 독성을 보이지 않았다. 지방세포 분화 중 세포 내 지방축적 및 ROS 생성량을 비교한 결과, 연화 열수 및 에탄올 추출물을 처리한 지방세포의 경우 지방축적량과 ROS 생성량 모두 유의적으로 억제되는 것으로 나타났다. 특히 연화 열수 및 에탄올 추출물을 처리함으로써 지방세포 분화와 관련된 전사인자인 PPARγ, C/EBPα 및 aP mRNA의 발현을 유의적으로 감소시켰으며, ROS의 생성과 관련이 있는 주요 유전자인 NOX4 및 catalase의 유전자발현 또한 유의적으로 감소하였다. 이 결과를 통해 연화 열수 및 에탄 올 추출물이 3T3-L1 지방세포 내 중성지방의 축적 억제 효과와 더불어 ROS 생성 억제에 효과적으로 작용함을 확인 하였다. 따라서 연화 열수 및 에탄올 추출물은 비만과 같은 대사증후군 관련 질환의 개선을 위한 천연물 기능성 소재로 의 활용이 기대된다.

Background : This study was carried out to investigate the changes to fatty acid, mineral, and ginsenosides contents in ginseng seed when they were stratified for different length of time and to determine whether variety had any effects on the changes. The aim was to improve the ginseng seed stratification process. Methods and Results : The ginseng varieties used were Geumpoong, Chunpoong, Yunpoong, and K-1. Stratifying periods treated on ginseng seed were 0, 20, 40, 60, 80, and 100 days. The main fatty acids of ginseng seed were oleic acid (C18 : 1, n9c) with a content of 78.40 - 79.20% followed by linoleic acid (C18 : 2, n6c). The main mineral in the seeds was potassium (K), at 1208.2 - 1337.6 ㎎/100 g. The main ginsenosides in ginseng seed were ginsenoside Re and Rb1. Increasing the length of the stratification periods led to increases in oleic acid content (60 - 80 days), however after this the content declined. In contrast, linoleic acid content fell as the stratification period increased. K, P, Mg, Ca and Na content rose as the stratification period increased. The ginsenoside Re content of Chunpoong and K-1 cultivar seeds also rose as the stratification period increased which meant that total ginsenoside content increased. However, ginsenoside Re content rose in Geumpoong and Yunpoong seeds, but total ginsenoside content decreased as the stratification period increased. Conclusions : Some beneficial compound in ginseng seed rose as the stratification period increased. Therefore, ginseng seed stratification could improve the food value of ginseng.

This study was conducted to investigate the effects of mixed-sowing of legume forage and applying of cattle manure on the productivity of organic rye to provide dairy farmers with safe organic feeds. Also the present study aimed to evaluate optimal applying level of cattle manure and carrying capacity of Korean native cattle (Hanwoo) per unit area. The amount of crude protein was significantly higher in the mixed-sowing of legume forage (average 760~786 kg/ha) than in the single-sowing of rye (average 353 kg/ha) (p<0.05). The mixed-sowing of forage peas and the single-sowing of rye tended to improve by increasing the level of nitrous fertilization rather than the fertilization treatment. The amount of crude protein on the rye according to the mixed-sowing of legume was significantly higher in the mixture (average 8.29~9.90%) than in the single (average 4.93%) (p<0.05). The comparison by the level of nitrogen fertilization indicated signifi-cantly high for the rye in 50 kg N/ha than in fertilization treatments (p<0.05). Total digestible nutrients (TDN) amount in the single-sowing of rye was average 46.86% and has lower than average 49.96~50.12% of the mixed-sowing of legume, and especially the mixed-sowing of forage pea was the highest with 54.55% in 150 kg N/ha for the level of nitrogen fertilization (p<0.05). The breeding ability of annual organic livestocks per unit area according to the feed value of rye presented significantly higher ability in the mixed-sowing of legume (3.72~4.12 heads) than the single-sowing of rye (average 2.26 heads) (p<0.05). By summarizing above results, the mixed-sowing of legume is required to improve the productivity and the feed value of rye for increasing organic livestock breeding ability in southern area of Gyeongbuk regions, and the study for identifying the appropriate fertiliza-tion level using livestock excretions is further necessary.

Soybean is one of the important food crop around the world. Especially in East Asia, it is the main ingredient for traditional food like soy sauce and soy paste. The double cropping system including soybean following onion, Chinese cabbage, and potato is widely adopted in Southern region of Korea. In this system, sowing date of second crop (soybean) can be delayed depending on first crops’ growth period and weather condition. When planting date is delayed it is known that soybean yield is declined because of shorter vegetative growth period and earlier flowering induced by warm temperature and changes in photoperiod. The objective of this study was to determine soybean growth and yield responses as plant populations at late planting date. Field experiment was conducted at Department of Functional Crop, National Institute of Crop Science, RDA located in Miryang, Gyeongsangnam-Do for two years (‘13-’14) in upland field with mid-late maturity cultivar Daewon. A split-plot block design was used with three replications. Main plots were three sowing dates from June 20 to July 20 with 15 days intervals, and subplots were 4 levels of planting densities. Data of maturity (R8) was recorded, yield components and yield were examined after harvesting. Experimental data were analyzed by using PROC GLM, and DMRT were used for mean comparison. Optimum planting population for maximizing soybean yield in late planting which compared with standard population. In mid-June planting, higher planting density causes increased plant height and decreased diameter which lead to higher risk of lodging, however, reduced growth period due to late planting alleviated this problem. Therefore higher seeding rates can provide protection against low seedling emergence caused by late planting in this region.

This study was carried out to investigate the effects of Salvia plebeia R. Br. ethanolic extract with differentaspects (stem/leaf and whole plant) on differentiation and lipid accumulation in 3T3-L1 preadipocytes. The morphologicalchanges and the degrees of lipid accumulation in 3T3-L1 cells were measured by Oil Red O staining and intra-cellular trig-lyceride (TG) assay. The mRNA expressions of special peroxisome proliferation activated receptor- genes (PPAR), CCAAT/enhancer-binding protein (C/EBPα), fatty acid synthase (FAS) and lipoprotein lipase (LPL) were detected by reverse tran-scriptase polymerase chain reaction (RT-PCR). The 50% ethanolic extracts (100μg/mL) of stem and leaf (SALE) and 30%ethanolic extracts (100g/mL) of whole plant (SAE) from Salvia plebeia R. Br. were significantly attenuated lipid accumula-tion during adipogenesis in 3T3-L1 cells. Ethyl acetate-soluble fractions (50μg/mL) significantly inhibited lipid dropletaccumulation in 3T3-L1 cells. In addition, SALE induced down-regulation of specific adipogenic transcriptional factors (C/EBPα and PPARγ) and target genes (FAS and LPL) during adipogenesis. Salvia plebeia R. Br. may be used as a safe and effi-cient natural substance to manage obesity.
