  • The machine-to-machine (M2M) communication is featured by tremendous number of devices, small data transmission, and large uplink to downlink traffic ratio. The massive access requests generated by M2M devices would result in the current medium access control (MAC) protocol in LTE/LTE-A networks suffering from physical random access channel (PRACH) overload, high signaling overhead, and resource underutilization. As such, fairness should be carefully considered when M2M traffic coexists with human-to-human (H2H) traffic. To tackle these problems, we propose an adaptive Slotted ALOHA (S-ALOHA) and time division multiple access (TDMA) hybrid protocol. In particular, the proposed hybrid protocol divides the reserved uplink resource blocks (RBs) in a transmission cycle into the S-ALOHA part for M2M traffic with small-size packets and the TDMA part for H2H traffic with large-size packets. Adaptive resource allocation and access class barring (ACB) are exploited and optimized to maximize the channel utility with fairness constraint. Moreover, an upper performance bound for the proposed hybrid protocol is provided by performing the system equilibrium analysis. Simulation results demonstrate that, compared with pure S-ALOHA and pure TDMA protocol under a target fairness constraint of 0.9, our proposed hybrid protocol can improve the capacity by at least 9.44% when ${\lambda}_1:{\lambda}_2=1:1$and by at least 20.53% when ${\lambda}_1:{\lambda}_2=10:1$, where ${\lambda}_1,{\lambda}_2$ are traffic arrival rates of M2M and H2H traffic, respectively.

  • This study investigates the relationship between human resource capacity and financial and non-financial performance. We examine the previous studies on human resources and corporate performance, the performance factors of SMEs, financial performance and non-financial performance. Based on this research, model and research hypothesis were set up. According to study result, CEO's competency influences on both of non-financial and financial performances. The period of CEO's experience in one industry positively effects on filing number of intellectual properties(IPs). Firm's basic competency positively effects on non-financial performance but has meaningless impact on financial performance. The extent of education and experience of executive managers positively influences on filling number of IPs. The extent of education and experience of R&D personnel also positively effects on technology innovation output. Executive managers specialties may influence on long term performance but are identified that those have no influence on financial performance.

  • Tapeworms of the genus Spirometra are pseudophyllidean cestodes endemic in Korea. At present, it is unclear which Spirometra species are responsible for causing human infections, and little information is available on the epidemiological profiles of Spirometra species infecting humans in Korea. Between 1979 and 2009, a total of 50 spargana from human patients and 2 adult specimens obtained from experimentally infected carnivorous animals were analyzed according to genetic and taxonomic criteria and classified as Spirometra erinaceieuropaei or Spirometra decipiens depending on the morphology. Morphologically, S. erinaceieuropaei and S. decipiens are different in that the spirally coiled uterus in S. erinaceieuropaei has 5-7 complete coils, while in S. decipiens it has only 4.5 coils. In addition, there is a 9.3% (146/1,566) sequence different between S. erinaceieuropaei and S. decipiens in the cox1 gene. Partial cox1 sequences (390 bp) from 35 Korean isolates showed 99.4% (388/390) similarity with the reference sequence of S. erinaceieuropaei from Korea (G1724; GenBank KJ599680) and an additional 15 Korean isolates revealed 99.2% (387/390) similarity with the reference sequences of S. decipiens from Korea (G1657; GenBank KJ599679). Based on morphologic and molecular databases, the estimated population ratio of S. erinaceieuropaei to S. decipiens was 35: 15. Our results indicate that both S. erinaceieuropaei and S. decipiens found in Korea infect humans, with S. erinaceieuropaei being 2 times more prevalent than S. decipiens. This study is the first to report human sparganosis caused by S. decipiens in humans in Korea.

  • In this study, the Inter-Korea Fisheries Cooperation Project was divided into four categories: North Korea's Fisheries Infrastructure Development Project, Fisheries Cooperation Project, Human Exchange Project, and North Korea Fisheries Investment Project. First, North Korea's fisheries infrastructure development projects include North Korea's fisheries resource research project, it's fisheries resource development project, and joint enforcement on illegal operation of Chinese ships. Second, fisheries cooperation projects include the operation of the North-South common fish area in the West Sea, the fishing project in North Korea's East sea, and the import of North Korean seafood. Third, human exchange projects include training of aquaculture technicians in North Korea, technology transfer and training of fishing vessels, and boarding of North Korea's fisherman in Korean fishing vessels. Fourth, North Korea's fisheries investment projects include aquaculture facilities and aquaculture feed support, aquatic product processing facilities and technology transfer, and fishery equipment support. However, as international sanctions are maintained in the international community to North Korea, Inter-Korea Fisheries cooperation, however, should be promoted according to the level of easing of international sanctions as international sanctions are maintained in the international community to North Korea. First, North Korea's fisheries resource research project, North Korea's fisheries resource creation project, joint enforcement on illegal operation of Chinese ships, and operation of the common fish area in the West Sea can be promoted if international sanctions are maintained at present, promote North Korea's fisheries resource research project. Second, boarding of North Korean's fisherman in Korean fishing vessels, conducting the fishing project in North Korea's East sea, and importing North Korean seafood can be aided if commercial transactions are possible with North Korea. Third, South Korea will support aquaculture facilities and aquatic feed, fisheries processing facilities and technology transfer, fishery equipment support, training of fisheries and aquaculture technicians, fishery fishing technology transfer, and training of fisherman when a comprehensive economic cooperation project is possible with North Korea.

  • Since environmental problems were globalized, discussions on 'Sustainable Development' started from Rio Declaration on Environment and Development(Rio Agenda 21). In Korea, the idea of 'Green Growth' was introduced and generalized since the celebration speech made on 8.15(Independence Day of South Korea) on 2008. And Low Carbon- Green Growth Basic Law was established on 2010. There are 3 strategies and 10 sub-tasks to achieve green country-traffic and green revolution of life. Family resource management is capable of changing life style from energy wasty to ecologically green. The value of family resource management plays a critical role in changing the lifestyle through influencing the goal and standard setting. So, this study is aimed to suggest the green value and green way of life from the perspective of family resource management. Results are as follow. First, the green value is to change from 'material-oriented' to 'people-oriented'. The 'material-oriented value pursues pleasure from possessing, but the 'people-oriented' value pursues pleasure from being itself. Second, the change from the value of 'human-mastery of the nature' to the value of 'mother -nature' is necessary. The value of 'human-mastery of the nature' seeks pleasure from the velocity and tangible outcome. But the value of 'mother- nature' seeks pleasure from the time to relax and slow way of life. 'Third, the change from the value of 'individualism' to the value of 'community sprit' is necessary. Individualism focuses on man's achievement, which may fall into family egoism. And the green way of life suggests the change from 'results-oriented' to 'enjoy the process itself", from 'consumption' to 'ecological restoration' and from 'work to home and then home to community'.

  • This paper aims to suggest a policy for biological resource based on a comprehensive understanding on biological resources. Biological resources are different from traditionally recognized viable organisms (Biodiversity) in ecosystems. Biological resources are culturable and replicable resources of living organisms such as tissues, cells and genes. Moreover, biological resources include human-derived biological materials. Biological resources is not simply a matter of science and technology. Biological resources should be dealt with as national resources. There are many international issues regarding biological resources, such as intellectual property rights (IPRs), safety on handling and distribution, material transfer agreements (MTAs) for mutual benefits and biological standards. Ethical debates are also being raised because biological resources are related with human-derived biological materials. Every nation has tendency to adopt its government policies to strengthen its sovereignty on biological resources and international cooperation. In addition, international linkages are essential for providing enhanced worldwide accessibility to biological resources. Japan has shown several international initiatives in the field of biological resources. Korea has just begun to design appropriate policies for the use and R&D of biological resources. Therefore, this paper suggests the following needs: 1) policy at the national level beyond the interests of researchers, 2) inter-ministerial coordination across government ministries, 3) expansion of scope and size of each BRC (Biological Resource Centers), and 4) building networks and systems such as national information center, representative centers by field, and each BRC.

  • The damage caused by natural and human disasters has been increasing year by year. While the damage from these disasters are unavoidable, reduction of damage level by proper establishment of control measures could be sufficiently achievable. Disaster prevention resources include resources introduced in the event of disaster, such as human, materials, equipments and facilities. Rapid yet proper inputs of these resources are the key factor to minimize any damages from the disaster. Currently, however, the standard and/or criteria for mobilization of the disaster prevention resources have not yet systematically established. Therefore, proper resource management as well as efficient resource input has not been in place. This research is an early stage construction of efficient mobilization resources, which had been irregularly loaded and applied before. Also this study has tried to provide a classification rule for efficient disaster prevention resource management and mobilization, and indeed, provide a foundation for efficient resource management system.
