In this paper, we propose a new logging and recovery scheme that is suited for the high-performance transaction processing system base on flash memory storage. The proposed scheme is designed by considering flash's I/O characteristic of asymmetric costs between page update/read operations. That is, we substitute the costly update operation with writing and real-time usage of snapshot log, which is for the page-level physical redo. From this, we can avoid costly rewriting of a dirty page when it is evicted form a buffering pool. while supporting efficient revery procedure. The proposed scheme would be not lucrative in the case of HDD-based system. However, the proposed scheme offers the performance advance sush as a reduced number of updates and the fast system recovery time, in the case of flash storage such as SSD (solid state drive). Because the proposed scheme can easily be applied to existing systems by saving our snapshot records and ordinary log records together, our scheme can be used for improving the performance of upcoming SSD-based database systems through a tiny modification to existing REDO algorithms.
Even though "An Outpost of Progress" and Heart of Darkness were based upon Joseph Conrad the sailor's same experience in Congo Free State, their narrative strategies are quite different. The realistic representation of "An Outpost of Progress," with which Conrad was not satisfied at all, was converted into the modernistic narrative strategy of Heart of Darkness so that the sympathetic power of the story should be improved. The conservative value system of realism is expressed by the omniscient author in "An Outpost of Progress," whereas the frame narrator of Heart of Darkness is proved to be an unreliable one whose norms and behavior are not in accordance with the implied author. The glorious history of the British Empire, which was proudly presented by the frame narrator at the beginning of Heart of Darkness, was strongly opposed by Marlow, another narrator, who said that the British Empire had been "one of the dark places of the earth" when ruled by the Roman Empire. The feeling of the frame narrator was uneasily changed into the gloomy mood when he described the Thames as the flow which "seemed to lead into the heart of an immense darkness" at the end of Heart of Darkness. Similar to the straightforward narrative strategy of representation in "An Outpost of Progress," the realistic approach of Part I in Heart of Darkness is considered by Conrad as insufficient to reveal the darkest truth of imperialism, which was declared by Kurtz as "The Horror! The Horror!" Thus Conrad uses the Chinese-box structure, in which Kurtz' episode is enveloped by Marlow's tale which is enclosed by the frame narrator's story, in order to penetrate into the mind of ordinary readers in the novelist's age of New Colonialism, while attacking the ideology itself of imperialism instead of critisizing its inefficiency and individualism.
It is common to say that Korean journalists' professionalism including the public broadcaster KBS is immature. This study used the Q methodology to explore the subjectivity that KBS reporters and citizens have formed about reporters' occupational achievements. we tried to find out the background and reasons of the subjective dimensions of journalists regarding the immature state of Korean journalists' professionalism. Under a condition for sorting of 'a reporter most likely to be promoted', using 95 statements related to the reporter's occupational achievements, 30 KBS reporters, 10 university students who were eager to be a journalist, and 40 ordinary people of various ages, a total of 80 participants took part in the Q sorting. A total of 3 Q factors were extracted, then analyzed in detail into a total of 6 reporter types divided into (+) and (-) sub types for each factor. As a result, six types of perceptions and attitudes were named as 'a professional reporter','a schemer reporter','an organizational loyalty reporter', 'a passionate reporter','a careerist reporter', and 'a reliable worker'. This study can be meaningful in that it further deepened and expanded the existing researches concerning Korean journalist's professional identity.
Purpose: The paper aims to: 1) identify the reasons for the low usage of recycled paper in domestic workplaces and the premature state of recycled paper industry; 2) assess the environmental effects of replacing domestically consumed copy papers with recycled papers; and 3) suggest ways in which the recycled paper industry can expand in South Korea. Method: Questionnaire survey with cluster sampling is used to identify the attitudes and behavior with respect to recycled copy paper, the results of which are analyzed using SPSS. The environmental effect of replacing copy papers with recycled paper is assessed through the Life Cycle Assessment approach and Paper Calculator V4.0. Result: While the respondent's experience in using recycled copy paper was relatively low, they tend to acknowledge the need for its use and show relatively high satisfaction with the quality of the recycled paper. The environmental benefits of replacing ordinary copy paper with 40%+ recycled paper under the 10% market share increase scenario amounts to 60,000 tons of CO2 emissions reductions. Conclusion: The results from the attitude survey and market research, five approaches to improving the recycled copy paper market are suggested.

Exposure of high concentration of ground-level ozone (GLO) can trigger a variety of health problems including chest pain, coughing, throat irritation, asthma, bronchitis and congestion. There are substantial human and animal toxicological data that support health effects associated with exposure to ozone and associations have been observed with a wide range of outcomes in epidemiological studies. The aim of the present study is to estimate the spatial distributions of GLO using geostatistical method (ordinary kriging) for assessing the exposure level of ozone in the eastern part of Texas, U.S.A. GLO data were obtained from 63 U.S. EPA's monitoring stations distributed in the region of study during the period January, 2012 to December, 2012. The descriptive statistics indicate that the spatial monthly mean of daily maximum 8 hour ozone concentrations ranged from 30.33 ppb (in January) to 48.05 (in June). The monthly mean of daily maximum 8 hour ozone concentrations was relatively low during the winter months (December, January, and February) and the higher values observed during the summer months (April, May, and June). The higher level of spatial variations observed in the months of July (Standard Deviation: 10.33) and August (Standard Deviation: 10.02). This indicates the existence of regional variations in climatic conditions in the study area. The range of the semivariogram models varied from 0.372 (in November) to 15.59 (in April). The value of the range represents the spatial patterns of ozone concentrations. Kriging maps revealed that the spatial patterns of ozone concentration were not uniform in each month. This may be due to uneven fluctuation in the local climatic conditions from one region to another. Thus, the formation and dispersion processes of ozone also change unevenly from one region to another. The ozone maps clearly indicate that the concentration values found maximum in the north-east region of the study area in most of the months. Part of the coastal area also showed maximum concentrations during the months of October, November, December, and January.

In ordinary modern wester expression 'the Renaissance' was used to denote the impact made by dead Hellenism civilization in western Christendom, particularly Italian literary and artistic movement at Northern and central Italy in the late medieval period. However, A.J. Toynbee examined the renaissance from the different aspect of view. In his great work "A Study of History" in vol. IX, he succeeded in establishing the theory of historic civilization encounters in space and in time; and in time, civilization of the present and the past or between dead and infant successor contacts on the analogy of parenthood and sonship in the relation of A n.0, pparentation-and-Affiliation. The distinguished his view of 'Renaissance' was illustrated in the sense of encounters between a grown-up civilization and the 'ghost' of its long-dead predecessor. The renaissances (by the process of evocation of ghost of its parent society) has not only one single aspect of literary and artistic field but also in politics, law, science and philosophy, languages and literatures and visual arts, and religion. The main theme of this study is to examine the development of libraries and its historical meaning through Toynbee's literary renaissance. His renaissance of Languages and Literatures has three typical steps: They are: 1st step-to restive the dead literature's remains: 2nd step-to remaster their meaning: 3rd step-to reproduce them in counterfeits... Through its first and second steps, collecting and editing, annotating by compiling an anthology, thesaurus, lexicon or encyclopedia, and in its third step publishing mostly imitation of classics took place. Toynbee depicted the five outstanding eminent representatives of literary renaissance who had a n.0, ppeared on the state of history down to the time of writing. They are: Assurbanipal, Constantine prophyrogenitus, Yung Lo, K'ang Hsi, and Ch'ien Lung and the last four had all been emperors of imperia rediviva. As the result of the examination of these five emperors with three steps of literary renaissance, the common result may be summarized as follows: 1. Those emperors of imperia rediviva interested in intellectual work and study, they also were deeply involved in collecting classics in an ostensible reason. 2. There were strong political intention of collecting materials as an a n.0, ppeasement policy of civilization by transferring scholars energies to an intellectual field. 3. Under the rulers of a resuscitated universal state, the literary renaissance were a product of political plane and that the total size of collection and work were huge. 4. Since there were strong exercise of sovereign power, an active censorship by distortion and elimination was inevitable. 5. There existed newly developed strained atmosphere between grown-up and long-dead parent civilization, whenever the book collection movement had occurred. 6. Over adhesion to the parent civilization caused imitation of classic work and the creative activities were stagnated.stagnated.
Purpose - As an important participant in the financial markets, the commercial bank will be impacted by the interest rate marketization. Owing to the special condition of China, this paper tries to explore the impact of operating mechanisms between interest rate marketization and the profitability of the commercial Bank. Research design, data and methodology - This paper applies time series data from 2005 to 2016. Due to the short period of time series, autocorrelation often occurs. Therefore, the fully modified least squares(FMOLS) will be used to conduct an empirical analysis. The reason is that it can move off the autocorrelation between variables and disturbance term. And FMOLS also can make estimated cointegrating parameters closed to normal distribution. More importantly, in order to avoid spurious regressions, the Augmented Dickey-Fuller Test will be used to verify the stationarity of all variables. The total return of asset is treated as the profitability of commercial bank. The net interest spread is treated as a measurement of interest rate marketization. Both are regarded as dependent variables. The non-interest income or gross revenues and impaired loans or gross loans are treated as independent variables. The sixteen representative listed commercial banks are divided into three categories (state-owned, share-holding and city-owned) to conduct an estimation. Results - Via empirical analysis, the findings show that the net interest spread has a positive effect on the profitability of the commercial bank. More specifically, 1% increase in the net interest spread will lead 0.157% increase in the profitability of state-owned commercial bank, 0.269% increase in the profitability of share-holding commercial bank and 0.263% increase in the profitability of city-owned commercial bank. If regarding the sixteen listed commercial city as a whole, 1% increase in the net interest spread will lead 0.267% increase in the profitability of the commercial bank. Conclusions - As the interest rate marketization, the importance of interest rate on the profitability of commercial bank has become more and more significant. The empirical evidences also prove that the net interest spread can bring about the change of the commercial bank's profitability. Therefore, policy-makers of commercial banks should fully understand the operating mechanism between them.
This study aims at exploring the employment experiences of people with psychiatric disabilities who look for job and work at workplace through deeply searching that of people with psychiatric disabilities from the point of their view. So this research shows how their employment experiences appears in our country and also what kind of meaning that gives to people with psychiatric disabilities. The Main question of this study is what the meaning and essence of employment experiences of people with psychiatric disabilities is. The qualitative research method was taken for widely understanding and lively writing employment experiences of people with psychiatric disabilities in the connection of their lives. Especially, it was set that phenomenological research methods introduced by Colaizzi's, which can be used for understanding the essential meaning of the experiences of research participants. The major themes could be analyzed as "Entering a narrow door", "Being raised on an unfamiliar stage", "Confusing in the fast world", "Enduring", "Adjusting to an ordinary life", and "Taking a step forward admitting their limitation". These are connected not in the state of independence state but dependence according to time flow. In this study the people with psychiatric disabilities in relation to employment are compared to salmons running back in a wild river. People with psychiatric disabilities have power through running back in their employment and lives like a long river. Even though there are difficulty things, they actively try to flow together with other people as mature people in our society. This research helps to make strategies of employment supports for people with psychiatric disabilities through their employment experiences.
Since the Hwang scandal, the South Korean state has expressed often-conflicting interests of encouraging stem cell research and the IVF industry to save the country and introducing the ethical regulation in conformity with "Global Standard." As the tightening ethical regulation of stem cell research has enervated the field of human Embryonic stem cell(hESC) research, somatic stem cells (re-)emerged as an alternative savior that could rescue the future of research communities, bio-industry, practicing doctors, patients and the nation itself from the crisis. The recent literature on Korean biotechnology, however, mainly focus on hESC and relatively little attention has been given to the rapidly growing field of research on somatic stem cells like hematopoietic stem cells(HSCs) or Adipose derived stem cells(ASCs). While the hESC therapy is often regarded as experimental and ethically controversial, the HSCs or Mesenchymal stem cell(MSC) therapies have already made their ways into people's everyday life through market without much public discussion. Many ordinary people in South Korea are familiar with the story of patients who survived leukemia with the HSCs treatment; the number of doctors who are actively marketing the ASCs therapies is on the rapid increase; the concept of cosmetic products made from ASCs is gaining popularity among consumers. In this context, this article argues that the current ethical debates solely focusing on hESC or on the state policy and research regulation are too limiting to fully illuminate the politics of stem cell technologies in South Korea.
According to Neo-liberalism, the privatization of social security systems is pivotal for a country's economic growth and the wellbeing of its people, because such systems hinder the full operation of the market, eventually leading the national economy to collapse. The Chilean case of pension privatization is often cited as a good evidence for the Neo-liberal argument. Neo-liberalists say that Chile has experienced a rapid economic growth and retirees have enjoyed a much more pension payment since the national pension system was successfully privatized in 1981. The primary purpose of this article is to provide a critical review on the results of the Chilean pension privatization reform implemented in 1981. This study is intended to give an objective understanding of the reform because the existing evaluations, particularly those from the neo-liberalism, over-emphasize the bright sides of the reform. for this purpose, this article will pay a particular attention to the change in the level of pension payment after the reform. The conclusion of this study is that, contrary to the argument of Neo-liberalism, the pension reform has lowered the level of pension payment and, compared to the old public pension, has made the lives of ordinary retirees less secure. Reorganization of the social security system is more desirable than privatization as a remedy for the current problems of the welfare state.
