We hypothesized that the unsaturated fatty acid palmitoleic acid (POA) could promote the expression of adipogenic/lipogenic genes in bovine skeletal muscle satellite cells (BSCs). The BSCs were cultured in a growth medium containing 10% fetal bovine serum. When the cells reached 80%-90% confluence, we used the differentiation medium with 5% horse serum for differentiation for 96 h. The differentiation medium contained 50 µM, 100 µM and 200 µM POA. Control BSC were cultured only in differentiation media. Compared with the control BSC, the POA BSC significantly up-regulated the expression of paired box 3 (Pax3) and paired box 7 (Pax7) and down-regulated myogenin gene expression (p < 0.01), which indicates a depression in muscle fiber development. However, all POA treatments up-regulated the expression of the adipocyte transcription factors peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer-binding protein alpha and beta (C/EBP α and C/EBP β), and other genes (p < 0.01) and increased the expression of PAT-family proteins and the concentration of adiponectin in the media. These results indicate that POA can convert part of BSCs into adipocytes.

A field determination method for small D-T neutron source yield based on the oxygen prompt gamma rays was established. A neutron-gamma transport equation of the determination device was developed. Two yield field determination devices with a thickness of 20 mm and 50 mm were made. The count rates of the oxygen prompt gamma rays were calculated using three energy spectra processing approaches, which were the characteristic peak of 6.13 MeV, the overlapping peak of 6.92 MeV and 7.12 MeV, and the total energy area. The R-square of the calibration curve is better than 94% and the maximum error of the yield test is 5.21%, demonstrating that it is feasible to measure the yield of D-T neutron source by oxygen prompt gamma rays. Additionally, the results meet the requirements for field determination of the conventional D-T neutron source yield.

The barren ground is an abnormal phenomenon of coastal ecosystem in which seaweeds, are destroyed and mostly replaced by the coralline algae containing the calcium carbonate components. To restore the seaweed forest, We have exerted an effort in the local areas, Samchuck, Korea, where barren phenomena are profound. Two methods of seaweed forest construction developed in the present study are underwater longline and seed transplantation for the brown seaweed Costaria costata, a fast growing edible seaweed. The sizes of C. costata attached on the underwater longline were $96.7{\pm}2.2mm$ of blade length and $83.6{\pm}7.7g$ of blade weight in April. Thereafter the sizes declined from May. Similar pattern was obtained from in the transplantation method with maxima of $90.4{\pm}15.8mm$ and $70.1{\pm}31.7g$ for blade length and weight, respectively in April. It appeared totality maturation from two methods in May. This maturation time is the same like that of wild C. costata.

본 연구의 목적은 한국과 중동지역의 국가간의 무역을 증대하기 위하여 한국과 중동의 무역패턴을 분석하는데 있다. 이를 위해 중동시장 현황을 조사하였다. 그리고 한국과 중동의 무역집중도와 무역특화도를 산출하여 한국과 중동의 무역 구조를 분석하였고 이를 통해 현재의 무역이 어떻게 진행되고 있는지를 파악하고 발전가능성이 있는 품목군을 도출하였다. 또한 이들 품목들 가운데 우리나라의 대중동지역 수출 활성화를 할 수 있는 품목군을 찾고 신시장 개척 및 미래성장동력을 제시하고자 하였다. 이를 통해 상품교역을 진흥하기 위한 방안으로 FTA체결과 현지 문화에 대한 이해를 늘리고 진출 시 빠른 적응을 위한 지원 프로그램과 전문 인력 양성이 필요하다고 판단된다. 본 연구는 이란의 경제제재 해제와 함께 찾아온 새로운 중동 붐을 적극적으로 활용하여 새로운 성장동력을 찾는데 이바지 하고자 하였다.

The study was designed to test anti-platelet effect and find out anti-platelet mechanism of extract from Gamisopunghwalheol-tang in vitro. The extract was investigated for the inhibition against the aggregation of human platelet suspensions induced from collagen by aggregometer. And also the extract was investigated for the inhibition against the aggregation of human platelet suspensions who is taking aspirin or clopidogrel induced from collagen by aggregometer. In collagen-induced platelet aggregation test, the extract significantly inhibited collagen-induced platelet aggregation in a concentration-dependent manner(p<0.05). The extract significantly inhibited collagen-induced platelet aggregation of human platelet who is taking aspirin or clopidogrel ing 0 mg/ml concentration(p<0.05). And the extract inhibited more ingpatients who is taking aspirin. These results show that the extract from Gamisopunghwalheol-tang has anti-platelet aggregation effect.

The investigation for the species composition and catch in the deep East Sea was carried out with commercial trawlers from 2004 to 2006. The catches were 6,043kg and were composed of 43 species with 34 hauls between 250m and 1,030m in depth. The principal species caught were Allolepis hollandi, red crab (Chionoecetes japonicus), Careproctus rastrinus, Argis lar, Chionoecetes opilio, Malacocottus gibber, Petroschmidtia toyamensis, Pandalus eous Makarov, and Dasycottus setiger. The rate of discarded catches in situ was about 50%. The diversity indexes of 2005 and 2006 were 1.152 and 0.878, respectively, and the evenness indexes at those years were 0.752 and 0.583, respectively, which implied one dominant species caught in 2006.

Heritage has entered the center stage of public diplomacy in East Asia. Competition to claim and interpret memories of World War II in East Asia has driven campaigns to list heritage items with UNESCO. State and non-state actors aim to use heritage listings to present a particular view of the war and related history to domestic and international audiences. This paper highlights the role of heritage soft power in East Asia's "memory contests" by examining the promotion of dissonant modern heritage in UNESCO's heritage programs. It conceptualizes heritage designation as a soft power resource in East Asia and presents a conceptual framework for understanding the hegemonic competition over the "memory regime" that emerged from the structural change in East Asia's regional order. It then uses this framework to analyze the processes by which state and non-state actors promote and/or object to UNESCO recognition of their sites and documents as heritage of outstanding universal value or world significance. The elements of this process are illustrated with case studies of two very different pieces of heritage, Japan's "Sites of the Meiji Industrial Revolution" and China's "Documents of Nanjing Massacre," which were enshrined as significant world heritage in 2015. While state and non-state actors in East Asia are increasingly recognizing the utility of heritage as a soft power resource for advancing specific historical narratives to an international audience, a backlash movement from civil society groups and governments in other countries prevents a purely unilateral interpretation. As a result, the utility of heritage soft power in this context must be significantly qualified.

The role of nodal station No. 14v (along the superior mesenteric vein) in lymphadenectomy for distal gastric cancer remains elusive. A 73-year-old woman underwent endoscopic submucosal dissection for gastric cancer, and was referred to our division for additional surgery because of pathologically non-curative resection. A laparoscopic distal gastrectomy with D1+ dissection was performed, with a final diagnosis of pT1bN1M0, Stage IB (2 nodal metastases to No. 6). Four months post-surgery, abdominal computed tomography revealed a 14-mm solitary nodule along the superior mesenteric vein. The lesion was excised and pathologically identified as a lymph node metastasis. Adjuvant chemotherapy with tegafur-gimeracil-oteracil potassium (S-1) was administered for the metastasis. Presently the patient survives without recurrence, 5.5 years after the second operation. Our findings suggest that there is lymphatic flow from the No. 6 to the No. 14v nodal station. Some patients with a No. 6 metastasis may benefit from a No. 14v lymphadenectomy, even in early-staged disease.
