The Alibaba Company, founded by Mayun in 1997, captured no.1 position in the global electronic commerce industry in 2016. Logistics strategy and paying system of the firm have greatly contributed to its success. The study aims not only to investigate the entrepreneurship of Mayun to inspire Korean youths with it, but also to help Korean E Commerce industry with logistics strategy of the Alibaba Group. The study adopts the management history approach through a literature survey on life time story, management philosophy of Mayun. Results from a study on Ma Yun's entrepreneurship style showed certain key characteristics: a global mindset, marketing and advertising proficiency, patriotism, a challenging spirit, and creativity. Alibaba's logistics system has greatly contributed to the success of the company's E commerce trade so far. However, some things are left to be desired in the following areas: logistics management system, logistics contract unit price, competitiveness in warehousing compared to rival Chinese companies, and last mile delivery.

Oogenesis process of ovary produces a lot of undifferentiated cells. Especially, the radiation exposure of early immature cells in the process of growth to oocyte causes serious disabilities. This study examined the radiation damage mechanism of undifferentiated cells and organelles in oogenesis process, and the radioprotection after injection of alliin. The ultrastructure after 7Gy X-ray irradiation on the white rat was observed in the experiment. The results is as follows. It was observed that the nucleus membrane of an oogonium was damaged and vacuolated in the several parts after 15 days of irradiation. The damage of mitochondria membrane and flow in cytoplasm after 20 and 30 days was found in the oogonium. After 40 days observation, peroxidation of fat droplets was found and organelles were tangled each other in ovary tissue. The partial damage of nuclear membrane in oogonium past 15 days after injection of alliin was found, but decreased remarkably. Mitochondria, Golgi body, and rough endoplasmic reticulum were also clearly observed, therefore, radioprotection effects in alliin was confirmed partially.

알리바바는 단기간에 세계 최고규모의 전자 상거래 기업으로 성장하였다. 어떻게 그렇게 단기간에 그것도 인터넷이 그렇게 완비되지 않은 중국에서 출발하여 세계적 기업으로 알리바바가 성장할 수 있었을까? 이 문제에 대한 답을 구하고자 한다. 알리바바는 개방형 혁신을 통한 세계 최고수준의 창조적인 전자 상거래 비즈니스 모델을 단기간에 완비하여 갔다. 아울러, 개방형 혁신이 초래하는 복잡성이라는 비용, 즉 기업을 와해하는 원심력을 강력한 새로운 중국 기업 문화 "마윈식 소비자 신뢰 관씨 문화"를 구축하여 극복하여 왔다. 본 연구는 알리바바의 역동적인 개방형 혁신의 과정의 창발성과 그 과정에서 발생하는 원심력과 복잡성을 억제하는 새로운 관씨 문화, 제도, 및 리더십의 지속적인 강화 과정을 분석한다.

Platelets originating from Megakaryocyte are sensitive to radiation along with white blood cells, and thus these platelets are used as an index of radiation hazard as they decrease in advance. Thus, when there is a scarcity of platelets, dot hemorrhage occurs and it leads to decrease of blood corpuscle and a decline in immunity. In particular, when 4~6 Gy whole body irradiation is received, after three weeks, the platelets will decrease to the lowest level, which can be a cause of death by bleeding and anemia. Therefore, this study tried to identify the mechanism of platelet damage and protection effect. The protection substance used in the experiment is Alliin, which is a component of garlic, and it was observed by an Transmission Electron Microscope(TEM) after its injection to the rat's tail vein. In the study, it was found that the cell membrane was severely damaged in a 10-day progressed platelet organ after receiving 5 Gy irradiation. It billowed as balloon-like figure and the glycocalyx became hyperplasia. The minute organ was damaged to the point that it was beyond recognition in a 20-day progressed platelet organ after receiving irradiation, and the cytoplasmic contents were exposed to epilepsy parts and outrageously damaged. Furthermore, the form of granules could also not be observed. A hole was formed in the middle, and the damaged organ was found in a 30-day progressed platelet. However, the form of granules was consistently maintained in the experiment group injecting Alliin, as with the control group, and there was no damage to the cell membrane recognized. Thus, it was possible to verify the effectiveness of radiation protection of the platelet when Alliin was injected to the blood vessel.

Liver tissue damage by a radiation exposure caused a jaundice and ascitic fluid e form harden atrophy. The reason for this lies in morphological damage of a liver cells. This study tried that observe damage mechanism of the cell organelles. It was especially observed mitochondria, endoplasmic reticulum and nuclear membrane associated with energy metabolizable. also, This study had with a radio-protector development research at the same time. Radio-protector was used to alliin that has an blood flow increase. Cell observation make used of transmission electron microscope(TEM). The result of an experiment, 7Gy of whole body irradiation was caused an inflammation in cell organelles and hypertrophy of the nucleus membrane. After 20 days, The hepatocyte has been observed in a damaged membrane on peroxisome, mitochondria and vacuole of the cell organelles. After 30 days, The hepatocyte has been observed in disconnected ribosomes on a rough endoplasmic reticulum. There was looked a giant lipoblast. There was clearly normal observed a mitochondria and nucleus membrane in the hepatocyte after alliin injection. aslo, It was no damaged the nucleus membrane. therefore, It was identified portion a radio-protector effect from alliin.
