Next Generation Open-Source Big Data Analytics... 2014-02-13
Writer: admin


On February 5th, Seoul National University announced that back in January, Department of Computer Science and Engineering Professor Byung-Gon Chun, Microsoft, and research teams at UCLA co-developed an open-source big data analytics stack REEF (Retainable Evaluator Execution Framework).


REEF is the next-generation resource manager similar to Apache YARN, Apache Mesos, Google Omega, and Facebook Corona which provides a centralized control plane abstraction which can be utilized to create a decentralized data plane for big data systems. Unlike traditional data-processing systems, which are built around a single programming model and a runtime engine, REEF allows for a distributed data analysis environment by reusing a variety of data-processing tasks for multiple higher-level applications.


Therefore, REEF applications allow for easier development of new data processes which can conveniently utilize existing frameworks. In addition, different data processing frameworks are integrated in order to optimize workflow for data processing operations, reduce data center costs, and shorten the overall analysis time.


Professor Byung-Gon Chun stated, “REEF is a big data analytics platform which significantly improves the efficiency of the analysis of big data. Active research can be performed to develop future big data analytic platform.”


REEF (www.reef-project.org) is licensed under Apache License Version 2.0 of the Apache Software Foundation and can be obtained on Github.


Professor Chun received his bachelors from the Department of Computer Science and Engineering at Seoul National University, masters at Standard University, and his doctorate at University of California at Berkeley. Professor Chun worked at Intel, Yahoo, and Microsoft, and last year returned to Seoul National University as an assistance professor.


<Figure Description>
This figure shows the REEF analytics stack in comparison to YARN and Hadoop (pre-YARN) analytics stacks. The REEF analytics stack focuses on organizing data processing tasks in a library form so that the higher-level applications can reuse the accomplished tasks (machine learning) and allow an integrated environment capable of processing a wide variety of applications.

Seoul National University College of Engineering Department of Material Science and Engineering Professor Byungwoo Park

 

 

On February 2nd, Professor Byungwoo Park, Department of Material Science and Engineering at Seoul National University, and Dr. Cheon Jung Kim, UC Berkeley, were able to drastically improve the performance of lithium batteries by utilizing a solid-phase reaction in order to evenly coat Li4Ti5O12  (LTO) with graphene.

 
When LTO cathode electrode is compared with conventional cathode electrode, LTO cathode electrode is observed to have a higher charge and discharge rate, therefore increasing the efficiency of batteries and is acknowledged by major companies and research labs as the next generation cathode material.  But due to low electrical conductivity, there were issues with commercialization. 


Professor Park said, “By coating the LTO material with a conductive material, the initial rapid reaction of lithium ions induces the non-conductive properties of the LTO,” and stated, “with this innovative research, advances in lithium battery recharge rates have been greatly increased and can be applied to many devices such as mobile phones, laptops, and electric cars.” 


Researchers were inspired by the properties of graphene, a next generation material, and decided to apply it to the LTO material.  By coating titanium-oxide with graphene-oxide, then mixing with the lithium precursor, the mixture is treated at a high temperature which reduces the graphene oxide.  This technique successfully synthesizes the graphene-coated LTO. 

 

Portions of this study was funded by the National Research Foundation of Korea and the United States Department of Energy.  This study was published as the cover story in the latest edition of Journal of Materials Chemistry A. 


The negatively charged graphene-oxide coats the positively charged P25 (titanium dioxide) through electrostatic attraction and then is mixed with Li2CO3 and heat treated in order to synthesize the graphene-wrapped LTO. 
Graphene is a two dimensional crystalline allotrope of carbon in a densely packed sp2-bonded atomic-scale hexagonal pattern.

Seoul National University Technology, Management, Economics and Policy Program professor Jina Kang co-authored a research paper with Samsung SDS Goon Ho Park Ph.D which was selected as one of the Top 4 research papers in 2013 from a well-known business journal on January 20th. 


Professor Kang’s team was nominated for the Tudor Rickards and Susan Moger Best Paper Award of 2013 in the Creativity and Innovation Management journal with their paper on “Alliance Addiction: Do Alliances Create Real Benefits?”. 


The Creativity and Innovation Management journal is a famous European journal published by CINet (The Continuous Innovation Network) and is highly regarded by the Social Sciences Citation Index (SSCI).  Every year, through strict evaluation, the Creativity and Innovation Management journal selects four research papers out of thirty candidates to receive the Tudor Rickards and Susan Morger Best paper Award. 


Professor Kang’s research paper observed the negative symptoms of an enterprise level coorporation.  Professor Kang stated, “generally, a cooperation between two companies is viewed in a positive manner.  However, this study reveals the other side.  As a company becomes addicted to the advantages of cooperative strategies, the innovation capacity is impacted negatively.”


The research team analyzed 1036 results from corporate alliances and have observed that companies who repeatedly utilized cooperation strategies reduced their innovation capabilities.  The repeated use of the cooperation strategy by the decision-making management results in ineffective resource distribution which negatively affects the company as a whole.  Because majority of these studies emphasize the positive aspects of a cooperation strategy, Professor Kang’s study has become a landmark study. 


Professor Kang graduated from the Department of Business Sciences from KAIST and received her MBA from Wharton School of University of Pennsylvania and has completed her doctorate in Business Administration from Anderson School of UCLA.  Professor Kang is the Director of Korean Society of Strategic Management, The Korean Society of Innovation Management and Economics, and is a board member of the Inspiring Insight in Business Society organization.  Her major areas of research are in business strategy and technology management. 


Goon Ho Park graduated from the College of Material Sciences and Engineering at Seoul National University and completed his doctorate in innovation through cooperation strategy.  Currently, Soon Ho Park Ph.D works at Samsung SDS as a consultant on the Technology Strategy team.

On January 20th, Seoul National University’s Department of Material Sciences and Engineering professor Euijoon Yoon and research professor Kundo Lee collaborated with Oxford University in England to expand the potential application of a new graphene material. 


This research showed the corners of graphene as a pure carbon structure instead of other elements.   This expands upon the possible uses of graphene such as gas sensors, energy converters, energy deposits, and applications in DNS analysis.   


Graphene is a two-dimensional carbon structure with high electrical conductivity properties and is extremely malleable.  In particular, the edges of the graphene structure shows interesting magnetic properties which can be used in next-generation devices. 


Unfortunately, application limit of graphene depends on the level of impurities present in the edges.  Seoul National University research professor Kundo Lee said, “Originally, there was a major challenge in the manufacturing process with other elements binding to the edge of the graphene, but this research shows the ability to add the desired elements into the graphene directly which can be applied in various applications.” 

The Seoul National University research team collaborated with the Oxford University research team by performing the molecular dynamic computer simulations while the Oxford University research team performed the high-resolution electron microscopy experiments, which proved a clean structure manufacturing process for graphene. 


This study was sponsored by the National Research Foundation of Korea and the Ministry of Education.  The results were published in the January edition of Nature’s sister publication, Nature Communications.

Love Charcoal Distributed for a Warmer Winter 2014-01-13
Writer: admin

Electrical and Computer Engineering performs community service in the summer and in the winter.  This community service event marks the fifth consecutive seasonal event, third annual event for winter. 

 

Charcoal was distributed to seniors who live alone in the Guhyeo 2-dong, Songpa-gu.  This year, with help from the Red Cross organization, a total of 50 undergraduate and graduate students, faculty, teachers, and professors were led by Professor Suhwan Kim. 

[Photo: Group Photo Before Volunteering]


The “Love Charcoal” event ran on the snowing morning from 9:00 to 12:00 on December 19th, 2013.  Due to the light snowing that morning, several volunteers were worried of the weather.  But as the volunteers donned their work gloves, rubber gloves, raincoats, and masks provided by the Red Cross, they were prepared for the hard work. 

[Photo: Students helping each other prepare]


After preparations, the volunteers arrived at the first home.  After unloading the trucks, the volunteers helped move the charcoal to the desired area.  Originally, the volunteers expected long distances to distribute the charcoal.  Fortunately, because the volunteers only had to travel short distances, the task became much easier. 

[Photo: Professor Suhwan Kim Advising other Volunteers]


Professor Kim advised the volunteers that the first and last individuals in the delivery line would have the most difficult tasks.  Due to the narrow storage space, the last volunteer had a difficult time stacking each charcoal briquette and later ended up with an aching back.  However, the volunteers endured the hardships and quickly continued to stack the charcoal briquettes. 

 

After storing the first home, the volunteers ventured to the second home without rest.  As the volunteers began storing the charcoal in the second home, the stacks of charcoal almost collapsed.  Fortunately, one of the volunteers was able to prevent the collapse and only a single charcoal briquette fell. 

[Photo: All the volunteers storing charcoal at the last home]


All the volunteers gathered together for the final home, due to the long distance from the trucks to the storage area.  Even though the distance was quite far, all the volunteers applied their “know-hows” from the other homes to smoothly and effectively finish the final home. 

 

After finishing the last home, the department provided lunch for all the volunteers.  As the volunteers were enjoying their lunch, they reflected on how there were more seniors to help than expected, but helping them all were not as difficult as expected. 

 

Generally, most individuals utilize their time for themselves and do not volunteer their time to help others.  Therefore, the department organized this volunteering event and taught the students the meaning of volunteering.  As alumni, friends, and families, it is highly recommended to take the time to volunteer.
