현재 세계적으로 식품환경은 엄청난 변화의 과정을 겪고 있다. 이러한 변화는 우리가 생각하는 것 이상을 뛰어넘고 있다. 문제는 무엇을 하느냐가 아니라, 방식인 것이다. 어떻게 하느냐에 따라서 1차 산업인 쌀 한 가마니의 부가가치를 상상할 수 없는 단계가지 높일 수 있는 것이다. 이는 농업을 뜻하는 애그리컬쳐(Agriculture)의 의미가 바뀌어 가고 있다는 것이다. 특히 우리나라는 세계화 농업, 선진화된 글로벌 농업을 인식해야만 한다. 이에 본고에서는 (주)샘터사에서 펴낸 '글로벌 스탠더드'CEO 6인조의 조언 중 (주)하림 김홍국 회장의 선진화된 글로벌 농업에 대한 이야기를 들어본다

The relationship between the properties of two kinds of calcined cokes and graphitized forming bodies were examined. The microstructures of the forming bodies are already determined to some degree at the stage of baking. Calcined cokes as well as baked forming bodies using the same coke as filler were heat treated at various temperatures and their structural and properties changes with heat treated temperature were studied. The transition in properties changes with heat treatment in forming bodies were observed around $2000^{\circ}C$. The characteristics of the finial graphite bodies are strongly dependent on the properties of the raw material cokes.

오늘날 세계 70여개 병원에서는 '헬프 메이트'라는 이름의 시중꾼 로봇들이 병원 복도를 굴러 다니면서 엘리베이터를 호출하고 음식을 운반하고 있다. 스웨덴에서는 장비메이커 일렉트로룩스사가 날씬한 둥근모양의 로봇 진공소제기를 생산 실험하고 있다. 미국 워싱턴 DC소재 스미소니언박물관의 몹시 붐비는 전시장에서 '미네르바'라고 불리는 안내 로봇이 방문객들을 안내하고 있다. 사람들이 길을 막으면 눈산을 찌푸리면서 비켜달라는 표정을 짓는다. 이런 실용로봇의 등장은 인조인간사회라는 새로운 시대의 개막을 마침내 예고하는것일까?

The number of patients with coronary artery disease and peripheral vascular disease are increasing, and the need of small diameter vessel is also increasing. We developed small diameter artificial vessel and experimented in vivo. We got allogenic valve from mongrel dogs, and removed all cells from the allogenic valve. Then, we seeded autologous bone marrow cells onto the decellularized scaffold. After implantation of artificial vessel into the canine carotid artery, we performed angiography regularly. In case of vessel occlusion or at 8 weeks after operation, we euthanized dogs, and retrieved the implanted artificial vessels. Control vessels were all occluded except one (which developed aneurysmal dilatation). But autologous cell seeded vascular graft were patent by 4 weeks in one, by 6 in one and by 8 weeks in two. Histologic examination of patent vessel revealed similar structure to native artery. Tissue-engineered vascular graft manufactured with decellularized allogenic matrix and autologous bone marrow cells showed that tissue engineered graft had similar structure to native artery.

Li-SGICs as a anode of lithium ion battery were synthesized by high-pressure method as a function of the Li-contents. The characteristics of these prepared compounds were determined from the studies with X-ray diffraction method and differential scanning calorimeter (DSC) analysis. From the results of X-ray diffraction, it was found that the lower stage intercalation compounds were formed with increase of Li-contents. The mixed stages in these compounds were also observed. In the case of the $Li_{30;wt%}$-SGIC, the compounds in the stage 1 structure were formed predominantly, but the structure of only pure stage 1, due to the structural defect of synthetic graphite, was not observed. The enthalpy and entropy changes of the compounds could be obtained from the differential scanning calorimetric analysis results. From the results, it was found that exothermic and endothermic reactions of Li-SGICs are related to thermal stability of lithium between artificial graphite layers.

Electrode surface reaction on three carbon materials(glassy carbon, synthesized graphite, graphite foil) in 0.5 M K2SO4 electrolyte is investigated by impedance spectroscopy during anodic polarization. The double layer capacitance of the graphite foil electrode is relatively higher than that of other two materials. The change of capacitance parameter C due to chemical adsorption on glassy carbon and synthesized graphite(PVDF graphite) is observed in 0.5 M K2SO4 solution at anodic polarization. In general, the faradic impedance on glassy carbon depends on anodic polarization, and the change of impedance parameter on graphite foil at anodic polarization is not remarkable, because this reaction is controlled by field transport.

This study investigated the conceptual constructs of ethical consumption beliefs and their impacts on the consumer attitudes toward eco-friendly faux leather apparel goods. The mediating roles of perceived consumer effectiveness and apparel environmental knowledge were examined in this research. A survey was conducted on female consumers between the ages of 20 and 50; subsequently, 300 responses were analyzed. The results of this study were follows: 1) The results of factor analysis and the reliability test on ethical consumption beliefs clearly showed factorial structures that include Social Responsibility, Eco-friendly Consumption, Animal Welfare, and Individual Enhancement. 2) The results of the mean scores of ethical consumption beliefs showed that respondents tended to consider Social Responsibility more important than the other three factors. Ethical consumption beliefs showed a significantly positive influence on consumer attitudes toward eco-friendly faux leather apparel products; in addition, Social Responsibility had the highest effect on product attitudes among the four factors of ethical consumption beliefs. 3) The perceived consumer effectiveness and environmental knowledge of apparel had important medicating roles in the relation-ship between ethical consumption beliefs and attitudes towards eco-friendly faux leather apparel products. This study highlighted a potential marketability of eco-friendly faux leather apparel products and that ethical consumption beliefs, perceived consumer effectiveness, and apparel environmental knowledge should be promoted among consumers to increase favorable attitudes towards these products.

K-SGICs(synthetic graphite intercalation compounds) were synthesized in a modified two-bulb pyrex tube. The pressure in the two-bulb tube was maintained at approximately $10^{-3}$ torr for the reaction of potassium and graphite. Deintercalation process of the K-SGlCs obtained by the modified method was heat-treated by keeping in liquid paraffin between $25^{\circ}C$ and $1400^{\circ}C$. The thermal stability and the temperature dependence of the K-SGICs were characterized using differential scanning calorimeter(DSC) analyzer. Enthalpy and entropy for K-SGIC formations were calculated by confirming the deintercalation and thermodynamic exothermic reactions depending on the various temperatures. The structure changes and thermal stability of K-SGICs during the deintercalation reaction of potassium ions and the interlayer spaces of the synthetic graphite were identified by X-ray diffraction(XRD).

Difficulty in exposing anastomotic sites is a frequently encountered problem during surgical repair of a distal aortic arch aneurysm via median sternotomy or lateral thoracotomy. Endovascular repair has th limitation that it usually requires surgical rerouting of some of the brachiocephalic branches in order to get sufficient length for proximal fixation of the stent-graft. To take advantage of each approach, we fixed the distal end of the prosthetic graft by means of a pre-mounted metallic stent instead of performing conventional surgical anastomosis during the repair of distal arch aneurysms with using median sternotomy and hypothermic circulatory arrest. We report here on our experience with such 3 patients.
