Since the inauguration of Defense Acquisition Program Administration(DAPA) in 2006, the national defense core technology research & development business has not only pertained to the weapons systems development but also to the improvement of the national science & technology capability via the acquisition of cutting-edge technologies. Furthermore, it has been closely related to the promotion of the defense industry and the mutual improvements of defense and civil technologies. The cyber warfare weapon system, a newly added national defense weapon system field since 2015, has become a promising weapon system branch for improving the national defense power as well as the national defense industry as shown in the case of Israel. By utilizing the existing result of the national defense core technology level, in order to establish the direction of technology planning of the cyber warfare weapon system, this paper analyzes the technology level and features of the cyber warfare weapon system in various aspects via comparisons with other weapons systems. The result of these analyses shows that the cyber warfare weapon system possesses a relatively high technology level due to the technology accumulation in the civilian sector while the relatively slow inclusion to the national weapons systems and the lack of the correspondence case regarding aggressive cyber responses in the defense sector yields a relatively low national rank. However, the technological gap between South Korea and the most advanced country in the field of cyber warfare technology is analyzed to be among the lowest, which indicates that with efficient and effective pursuits in terms of pthe weapons systems acquisitions as well as the core technologies research & development business, an outstanding cyber warfare capacity can be obtained in a short time.

Flash storage devices are very popularly used in portable devices such as cell phones, PDAs and MP3 players. As technology is improved, users want much bigger and faster storage system. Paradoxically, people have to wait more and more time proportionally to the capacity of their storage devices when these are trying to be recovered after file system crash. It is serious problem because booting time of devices is dominated by crash recovery of flash file system. In this paper, we design a crash recovery mechanism, named 'Working Area(WA hereafter)' technique, which has bounded crash recovery execution time. With WA technique, write operations to flash memory are only performed in WA. Therefore, by simply scanning the latest WA. We can recover a file system crash because every change for flash memory is occured only in latest WA. We implement the WA technique based on YAFFS2 and evaluate by comparing with traditional techniques. As a result, WA technique shows that its crash recovery execution time is 25 times faster than Log-based Method when we use 1 gig a bytes NAND flash memory in worst case. This gap will be futher and futher as storage capacity grows.

The SNS(Social Network Service or Social Network Sites), the concept which came along with the Web2.0 is on-line service which focuses on building social network communities of people which used to be established off-line. Foreign SNS sites such as Facebook, MySpace and Twitter and domestic SNS sites such as Cyworld, Me2Day are getting popularity continuously and became one of the most important application in internet environments. Since these SNS sites have the purpose of providing infrastructure which enable all the people to share his/her interests with all the other people, it is necessary to appraise whether these sites provide convenient interfaces with proper accessibility to handicapped people and old people who are considered having difficulties in using internet. Web accessibility refers to the practice of providing equal access to people of all abilities and disabilities. If the web accessibility of a SNS site is so low that handicapped people and old people cannot use it properly, those gaps between user groups may become social problems. Therefore, the paper appraised web accessibility of Facebook and Cyworld using automatic tool, KADO-WAH 2.0 and Standard guideline, WCAG 2.0 and suggested the improvement opportunities based on the results of the appraisal.

Due to the rapid development of medical information, vast amounts of medical data are accumulating, and such medical data is highly likely to be used as an important data for solving the aging population and the rapid rise in medical cost. Especially in Korea, there are resident registration numbers and computerized usage data for all citizens, so it can be superior to other countries in terms of medical infrastructure that can utilize big data. The purpose of this study was to analyze the factors affecting the mortality and death rate of Gangwon using the Big Data and the National Statistical Office data centered on Kangwon province. As a result of analysis, major variables related to the mortality rate of Gangwon were hospital infrastructure utilization rate, income level, aging population and population density. Therefore, inequalities due to income disparities and insufficient local medical infrastructures were affecting the local mortality rate, and policy support was needed to improve the local hospital infrastructure and income level. The results of this study were meaningful in that medical big data were used to analyze the deaths of people in Gangwon, and the causes of the deaths were analyzed through various social indicators and correlation analysis.

Korea has set up a radiation emergency planning zone based on the 「Act on Physical Protection and Radiological Emergency」 to protect residents living near nuclear power plants in the event of nuclear disasters. Little research has been conducted on the appropriateness of existing nuclear evacuation facilities because of a general lack of interest in nuclear accidents. This research addresses this gap by analyzing the location adequacy of evacuation facilities in Busan's emergency protection planning area based on vulnerable populations and accessibility analyses. The Gijang-gun which has the greatest risk, shows that only 4.05% of the total urban area was included in the evacuation service area within 5 minutes while only 36.93% of Geumjeong-gu and 37.23% of Haeundae-gu were included in the evacuation-enabled area. In addition, evaluation facilities in the elderly population hotspots were lacking, and there was a wide gap between dongs within the same Gu. Thus, additional evacuation facilities need to be designated and installed considering the spatial equity between areas and safety of both the public and vulnerable populations.

The sudden emergence of China as a superpower in world politics and economics is apparently a big surprise. This, however, is not an unusual incident. As far as the Chinese are concerned, they say that China is simply running almost the same track that its neighboring countries. In the recent years, a number of experts and scholars have expected that the emergence of China as a great economic power will be argued as a major issue in world politics and economics. So its economic progress will require experts and scholars to watch carefully how China is going to change. It certainly has created an atmosphere that most of the world leaders, experts and scholars are very concerned about China's remarkable performance in its economics and then willing to accept China's rapid growth as an urgent matter. Many experts and scholars began to analyze carefully the factors that have contributed to the rapid growth. Foreign direct investment (FDI), import-export, and economic reform were then listed as the most important factors. As a result, philosophy of economics, analytical economics, and economics are immediately needed for China who is at the moment very anxious to sustain the stable and continuity of rapid economic growth. But unfortunately China does not even recognize the reason why they need to adopt these economic concepts and methods.

This paper analyzes which of the military sub-fields has an effect on a soldier's evaluation of South and North Korean military power. There are three objectives of this paper. First, it is to analyze whether the South is superior to the North in the overall military power and military sub -fields, without the presence of the US armed forces in South Korea. Second, it is to assess which of the military sub-fields influences the overall evaluation of military power through a regression analysis. Finally, it is to look at whether the professional soldiers have a motivational bias, due to an argument that the military personnel tend to exaggerate the inferiority of their own military power to get more budget for defense construction. Research in 2002 and 2003 tell us that South Korean military power is slightly inferior to North Korea's. However, research in 2005 shows that military power of South and North Korea is almost equal. The sub-fields in which South Korea is superior are in the order of War Sustainability, Information Warfare, Air Force, and Navy. North Korea is regarded to be superior in the fields of Atomic Biological Chemical Warfare Capability, Special Force, Reserve Mobilization, and Army. The higher ranked soldiers tend to evaluate that the North is superior to the South.

Scholarly monographs have been a main vehicle for knowledge representation and transfer as well as an important research outcome. University presses have long been considered as the last bastion for scholarly monographs that have low commercial prospect. Until now there has not been a systematic data analysis regarding scholarly monograph production by university presses in Korea. In this paper, we collected bibliographic records of university presses' monograph publications between 1950 and 2015 using the National Library of Korea's online catalog system. A total of 21,015 records were used in the analysis. In particular, for monographs published between 2001 and 2015, we categorized them into scholarly monographs and non-scholarly monographs. University presses' publishing showed sharp increase during the 1990's but is in decline after its peak in 2005. University presses seem to have engaged in publishing more non-scholarly monographs than scholarly monographs by a ratio of 6:4. Large university presses in size seem to produce higher proportions of scholarly monographs than smaller presses. In terms of authoring types, single authorship accounts for the highest proportion and on the increase. However, edited books are losing ground as translated books seem to hold steady. Monographs in social sciences have been published more frequently than any other subject areas as there seem to be significant discrepancies among subject areas in terms of the scholarly monograph proportion.
