Vingroup JSC (formerly Technocom) was founded in Ukraine in 1993 as an instant noodle factory. Since then, the Group has expanded into many other industries, placing tourism and hospitality as their first stepping-stone, then venturing into retail, real estate, education, and recently shifting towards a promising industrial and technology industry. Vingroup has now become the largest conglomerate in Vietnam in terms of market capitalization (VnExpress International, 2019). Having established a solid foundation in the Vietnamese market, Vingroup is eyeing the new promising yet challenging international market, with its competitive advantage in industrials and technology. Standing at a crucial juncture in its ascent, the conglomerate must implement a comprehensive and long-term strategy to reach its next milestone. In 2016, Vingroup primarily focused on four main business segments, encompassing property, hospitality - entertainment, consumer retail, and social infrastructure services. Over the course of two decades, Vinpearl and Vincom have grown into the market-leading hospitality and shopping malls brand in Vietnam. The brands’ establishment coincided with the flourishing economy of the country in the early 2000s, therefore, quickly achieved market dominance. Having such favorable conditions, the Group continued its expansion and investment in other backboned industries, which has reaped correspondingly fruitful results. The key success factors of Vingroup lies in an entrepreneurial mindset, speed, perfectionism and discipline, and last but not least, the national spirit. These traits have allowed the Group to unleash its potential capabilities and go beyond all boundaries. Both small-and-medium-sized companies and big firms can take Vingroup as a lesson for their strategy and corporate culture so that they can lead successful and sustainable growth in today’s competitive market.

Objective: To evaluate the causes and treatments of patients with malignant central airway obstruction (CAO). Subjects: 37 patients were diagnosed with malignant CAO at Respiratory Center of Bach Mai Hospital. Methods: Retrospective and Prospective, descriptive study. Results: Average age was 53.8 ± 13.1 years. CAO occurred mainly in the 45-59 age group and in men more than women. No significant differences between the number of patients with cancer originated from in (group 1) and out (group 2) of the airway with regard to the number of patients, degree of stenosis and location of stenosis. In group 1, NSCLC accounted for the majority. In group 2, squamous-cell esophageal carcinoma had the highest proportion. The prevalence of patient having treatment was higher than not having treatment statistically. In the treatment group, the number of participants undergoing a combination of airway stent insertion and balloon dilatation was predominant. There were no significant differences in causes or locations or degrees of stenosis respecting treatment modalities. Participants having comfort after treatment accounted for the majority. In no treatment group and treatment group, cumulative proportions surviving were 0% (at 11th month) and 44.3% (at 9th month), respectively. The survival time in the treatment group (15.1 ± 3.4 months) was statistically longer than in no treatment group (4.4 ± 1.9 months) (p = 0.031). Conclusions: Causes of malignant CAO are varied and induce a variety of location and degree of stenosis, thereby leading to diverse treatments. Clinicians need to consider having appropriate treatments for patients to increase their comfort and survival time.
Feasibility study of ultra-low NOx Gas turbine combustor using the RML combustion concept
Tien Giap Van,Jeong Jae Hwang,Min Kuk Kim,안국영 대한기계학회 2016 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.30 No.12
A new combustion concept, the so called RML, was investigated to validate its application as a gas turbine combustor for combustor outlet temperatures over 1973 K. The feasibility study of the RML combustor was conducted with zero dimensional combustion calculations. The emission characteristics of RQL, LEAN, EGR and RML combustors were compared. The calculation results showed that the RQL combustor has lower NOx emissions than the LEAN at high outlet temperature. NOx emissions of the RML combustor at equivalence ratio of the rich chamber of 2.0 can be reduced by 30 % compared with the EGR combustor, and lower than the RQL combustor at a combustor outlet temperature over 1973 K. However, the CO emissions of the RML combustor were higher than those of the LEAN and EGR combustors. Also, the possibility of applying the RML combustor to gas turbines was discussed considering residence time, equivalence ratio of the rich chamber and recirculation rate. Although further research to design and realize the proposed RML combustor is needed, this study verified that the RML concept can be successfully used in a gas turbine combustor.

사과는 타가수분 작물이어서 사과원의 안정적인 결실을 위해서는 자가불화합성 유전자형이 다르고, 주 품종과 친화성이 있는 품종을 혼식하여야 한다. 주 품종에 비해 개화가 빠른 품종을 수분수로 심어야 하지만, 수분수로 활용하는 품종의 꽃피는 시기에 대한 정보는 부족하여 수분수 선정에 어려움이 있다. 사과 개화기에 저온이 상습적으로 내습하는 지역에서는 만개가 아주 빠르거나 개화가 늦은 품종의 도입이 바람직하나 품종의 개화 관련 정보가 없다. 사과 주요 품종의 생물계절 조사를 통해 후지를 기준으로 개화 순서를 확인할 수 있었다. 사과 수분수 선정 시 자가불화합성 유전자형뿐만 아니라 주 품종에 비해 개화가 빠른 품종을 선택해야 한다. 개화가 아주 빠른 품종으로는 홍로와 선홍, 개화가 빠른 품종으로는 썸머프린스, 시나노골드, 루비에스, 아리수, 감홍 품종이 있다. 후지와 비슷한 품종으로는 쓰가루, 썸머킹, 황옥이 있으며, 후지보다 개화가 늦은 품종은 피크닉 뿐이었다. 피크닉은 후지 품종에 비해 개화가 늦어 수분수로는 부적합 하나, 개화가 늦어 늦서리 상습지에는 저온피해를 회피할 수 있는 품종이다. 썸머킹은 중심화 개화에서 만개기까지의 기간이 짧아, 인공수정 기간이 짧은 품종이다. 개화기간은 홍로, 루비에스, 썸머프린스가 14일로 길고, 후지는 12일이다. 사과 대목에 의한 개화차이는 없는 것으로 나타났다. 사과 주요 품종의 개화 특성 정보제공으로 농가의 품종 및 수분수 선택 자료로 활용할 수 있으며, 저온상습지에 만기개화품종 선택으로 농가의 기상재해를 회피할 수 있을 것이다.
