  • In this study, the impact of sand and weathered granite soil is analyzed by changing the internal temperature from $20^{\circ}C{\sim}70^{\circ}C$C by installing a heating coil inside the triaxial cell. To check the effect on weathered granite soil due to increase of temperature and number of heating-coiling cycles are analyzed by measuring the temperature by using thermometer installed inside the triaxial cell and due to that deviator stress also occurred during the consolidated undrained test. To analyze the effect of weathered granite soil with change of temperature during undrained testing. The deviator stress and pore pressure is measured. As a result, pore pressure increases and the deviator stress decreases with rise of temperature.

  • The year 2010 has been regarded as a year of China's assertive diplomacy. A series of China's behavior--including China's critical reaction to the U.S. for its sales of weapons to Taiwan, the Dalai Lama's visit to President Obama, China's arbitrary designation of 'core interests' over the South China Sea, China's inordinate reactions to the sinking of the Cheonan and Yeonpyeong bombardment, and China's activities in the Senkaku/Diaoyu island areas--has served as the witnesses to China's assertive diplomacy in 2010. The major causes of China's assertive diplomacy can be summed up by three factors: potential power transition from U.S. to China; emerging China's nationalism; and the recession of the Tao Guang Yang Hui as a diplomatic principle. But a majority of Western sinologists claim that China's assertive diplomacy is defensive in terms of its character. China's neighboring states, however, perceive its assertive diplomacy as diplomatic threat. Due to these states' geographical proximity and capability gaps with China, these neighbors experience difficulties in coping with China's behavior. In particular, China's coercive economic diplomacy, in which China tends to manipulate the neighbors' economic dependency on China for its diplomatic leverage, is a case in point for China's assertive diplomacy. China's assertiveness seems to be continued even after the inauguration of Xi Jinping government. Although the Xi government's diplomatic rhetorics in "New Type of Great Power Relationship" and the "Convention for Neighboring States Policy" sound friendly and cooperative, its subsequent behavior, like unilateral announcement of Chinese Air Defense Identification Zone (CADIZ), does not conform with its rhetoric. Overall, China's assertiveness has been consolidated as a fashion of its diplomacy, and it is likely to continue in its relations with neighbors. As a neighboring state, the ROK should approach to it with more balanced attitude. In addition, it needs to find out a new diplomatic leverage to deal with China in accordance with its security environment, in which China plays a growing role.

  • With trend of container ships becoming larger and faster, the environment surrounding ports in North-East Asia is rapidly changing. Korea's largest port of Busan processed more than 10 million 20- feet equivalent containers in 2003, surpassing the 10-million TEU mark for the first time in its three decades of operation. However, the Port of Busan , the world's third-largest port in 2002, was eclipsed by Shanghai since July in 2003. The first massive strike of truckers crippled the Korea's logistics system in May and in September, the Port of Busan suffered from the second strike of truckers and damage by a powerful typhoon. By contrast, the port of Shenzhen in China increased its container-processing volume by 39.9 percent to 10.65 million TEU in 2003, and Shanghai, which passed Busan in terms of container volume in the middle of last year, further consolidated its position as the world's No. 3 port with an annual volume of 11.28 million TEU. After all, Busan recorded an annual container volume of 10.40 million TEU, slipping to fifth in rankings in 2003 and Busan's bid to become a Northeast Asian hub has suffered a further setback as these chinese ports overtook the port of Busan. But the port of Busan is located in the main trunk liking North America, Europe and South-East Asia. Once the project of Busan Newport is accomplished and the railway between South and North Korea is connected to TCR and TSR, the Port of Busan will have the most potential to become the international logistics center as the starting point of the land and sea routes encompassing all over the world.

  • Objectives: Immunization is considered one of the most successful and cost-effective public health interventions protecting communities from preventable infectious diseases. The Korean government set up a dedicated workforce for national immunization in 2003, and since then has made strides in improving vaccination coverage across the nation. However, some groups remain relatively vulnerable and require intervention, and it is necessary to address unmet needs to prevent outbreaks of communicable diseases. This study was conducted to characterize persistent challenges to vaccination. Methods: The study adopted a qualitative method in accordance with the Consolidated Criteria for Reporting Qualitative Research checklist. Three focus group interviews were conducted with 15 professionals in charge of vaccination-related duties. The interviews were conducted according to a semi-structured guideline, and thematic analysis was carried out. Data saturation was confirmed when the researchers agreed that no more new codes could be found. Results: A total of 4 main topics and 11 subtopics were introduced regarding barriers to vaccination. The main topics were vaccine hesitancy, personal circumstances, lack of information, and misclassification. Among them, vaccine hesitancy was confirmed to be the most significant factor impeding vaccination. It was also found that the factors hindering vaccination had changed over time and disproportionately affected certain groups. Conclusions: The study identified ongoing unmet needs and barriers to vaccination despite the accomplishments of the National Immunization Program. The results have implications for establishing tailored interventions that target context- and group-specific barriers to improve timely and complete vaccination coverage.

  • Recommendaton: These are the highlights of the findings of the Timber Consumption Survey carried out by the Project in 1966, and covering consumption for the period from 1961 to 1965. The survey was oriented towards consumption for structural, commercial and industrial purposes and existing estimates for local (village-level) consumption as fuel and the like were adopted. A full report on the survey was submitted to the Bureau of Forestry in 1966. Long-term Trends: After allowance for anticipated population increase, this ten year's increase in industrial wood consumption represents a gain of about 30% in per capita consumption (from 0.0913 cu.m. per capita to 0.118 cu.m. per capita). This is only about half the expected general economic growth of about 75% (7% per annum). It is therefore likely (a) that the 1975 estimate is conservative, (b) that the consumption demand beyond 1975 may be expected to build up at a greatly increased rate. Estimated income elasticity coefficients are high, and with expected ir,creases in prosperity and population, the consumption is expected to rise to 10 million cu. meters by the year 2,000. Consumption Pattern: The breakdown of industrial consumption (1965) is given in Table 4-2, showing sawnwood consumption as the most important in 1965. The upward trend in all sectors over the 1961-65 period is expected to continue. The general consumption pattern is expected to change through 1975 with a sharp increase in the relative importance of pulp products (to 30% of total consumption) offset by declining relative importance of sawlogs. The following recommendations follow from the study: (i) Industrial forests. - A programme of establishment of consolidated industrial forests should be initiated as a matter of urgency. (ii) Fuelwood forests - Properly sited, protected and managed fuelwood forest, worked on a 20-year rotation, should be established as a nation wide basis. (iii) Hardwood utilization - Detailed investigations are required into the use of indigenous hardwoods for the pulp, particle board and hardboard industries. (iv) Mining timber - Preservation treatment of all mining timber should be enforced by law. (v) Sawmills - Licencing restrictions should be enforced to reduce the number of small, inefficient sawmills. b. Extension work should be undertaken bv government to improve sawmilling practices.

  • Objectives: Eight constitution medicine (ECM), which was first introduced in 1965, has been further developed and refined over the decades, and has consolidated its foundation through many studies on theories, diagnosis and clinical application. However, there have been few reviews on dissertations of ECM. In this study, we reviewed previously published studies related to ECM. Methods: We reviewed a total of 55 ECM-related studies published from 1965 to 2010 found on PubMed and various domestic Oriental medicine journals. Each thesis was classified as a theoretical, diagnostic, or remedy-related study. Results: 1. In the review of theoretical studies, shortly after ECM's introduction in 1965 by Kwon, the authors found studies on constitutional diseases, diets and food table which helped establish the background of ECM. ECM has further developed by comparing its theories with Sasang constitutional medicine, Huang-di-nei-jing, Saam, and Taegeuk acupuncture theories. 2. Research on diagnosis has been focused on its objectivity and accuracy. Constitution could be diagnosed by pulse-taking. To compensate for the lack of accuracy innate in pulse-taking, the Eight Constitution Questionnaire has been invented. 3. Remedies can be largely divided into acupuncture and diet. There were case studies comparing treatment effect of ECM acupuncture to other treatments. Diet related studies were carried out in the fields of immunology and nutrition. Conclusions: The authors reviewed studies that contributed to improved understanding of theories and clinical implications of ECM. Although there were various approaches to its theoretical and clinical grounds, more clinical research is needed. There is also a need to evaluate the accuracy of the experts' diagnoses of the constitution. The relationship between the diet and constitution also needs further research.

  • The government real estate policy has repeatedly relaxed and reinforced controls under the mutually contradictory targets. Switching over the supporting policy after the IMF crisis to the regulating policy from 2003, the government housing policy began to generate ill effects due to various regulations. This stud carefully investigates and statistically tests the transmissions of variations in the housing prices between the metropolitan areas in the early stage of the preceding administration, under the effect of the supporting scheme, and those in the late stage, under the effect of the restricting scheme. The distinctive feature between the two periods is found to be much simplified interrelationships of the price variations in the latter period. Consolidated leading role of capital sphere, by concentrated economic strength, suggest the obvious imbalance between variations in the metropolis housing prices.

  • Purpose: Immediate loading of dental implants has been proved to be feasible in partially edentulous jaws. The purpose of this retrospective investigation was to assess the feasibility of immediately loading dental implants in fully edentulous jaws. Methods: A total of 24 patients aged between 53 and 89 years received a total of 154 implants in their edentulous maxillae or mandibles. Among the implants, 45 were set in fresh extracted sockets and 109 in consolidated alveolar bones. The implants were provisionally managed with chair-side made provisional resin bridges and exposed to immediate loading. Implants were followed up for 1-8 years, including radiographic imaging. Marginal bone levels were evaluated based on radiographic imaging. Results: A total of 148 out of the 154 implants survived over the follow-up period of 1 to 8 years, giving a survival rate of 96%. The time or region of the implantation, the pre-implant augmentation, and the length and diameter of the implants had no statistically significant influence on the survival or the success rate. The marginal bone level remained stable with only minimal loss of 0.3 mm after 60 months of loading. Conclusions: Within the limitations of this study, immediate loading is feasible for dental implants in edentulous jaws.

  • Concerning this nation's M&A system, it is expected that standards of limitation on ownership is considerably modified and alleviated. This would allow companies to freely merge with each other, raising the efficiency of the whole national economy and ultimately benefiting all economic subjects. Another goal of business merger lies in adjusting net income or reducing tax amount. The income and the amount are to be financially reported. If merger between companies does not create any synergy effect, but just contributes to net income increase or tax reduction for the purpose of the parties' financial reporting, it might distort a rational distribution of wealth over all facets of economy. Merger whose goal is to create the most desirable synergy effect should be positively encouraged, but that whose goal lies in tax avoidance needs to be strongly restricted. Thus the purpose of this study was to find how to improve this nation's merger-related taxation system. For the purpose, this researcher investigated problems of existing tax supports to merger, which meets related taxation requirements, especially in terms of liquidation income, appraisal profit from merger, fictitious dividend and requirements for taxation. Among the problems, the study found, the biggest thing was that liquidation income or deficit carried forward, if any, is subject to be prior deducted from surplus, so the income is likely to generate. To raise the consistency of this nation's taxation on business restructuring, existing local systems in regard to merger, division, investment in kind and dividend-exclusion method need to be reconsidered following the introduction of consolidated taxation system.

  • To identify the cause of the error and maintain the health of system, an administrator usually analyzes event log data since it contains useful information to infer the cause of the error. However, because today's systems are huge and complex, it is almost impossible for administrators to manually analyze event log files to identify the cause of an error. In particular, as OpenStack, which is being widely used as cloud management system, operates with various service modules being linked to multiple servers, it is hard to access each node and analyze event log messages for each service module in the case of an error. For this, in this paper, we propose a novel message-based log analysis method that enables the administrator to find the cause of an error quickly. Specifically, the proposed method 1) consolidates event log data generated from system level and application service level, 2) clusters the consolidated data based on messages, and 3) analyzes interrelations among message groups in order to promptly identify the cause of a system error. This study has great significance in the following three aspects. First, the root cause of the error can be identified by collecting event logs of both system level and application service level and analyzing interrelations among the logs. Second, administrators do not need to classify messages for training since unsupervised learning of event log messages is applied. Third, using Dynamic Time Warping, an algorithm for measuring similarity of dynamic patterns over time increases accuracy of analysis on patterns generated from distributed system in which time synchronization is not exactly consistent.
