Under the inhumane oppression of imperialism, the Third World's political violence has been often represented as an immediate and explosive one with an instant, concentrated visibility. Yet the ecological and psychological exploitation of the Third-World countries by empires, as Rob Nixon insists, shows the relative invisibility of slow violence. This paper is to reveal this slow violence of the marginalized areas symbolized as the lowland. Although Arne Naess' deep ecology promotes the inherent worth of living beings regardless of their instrumental utility to human needs. this paper deals with three postcolonial ecological textbooks which criticize the white-centered deep ecology: Amitav Ghosh's The Glass Palace, Jhumpa Lahiri's The Lowland, and Barbara Kingsolver's The Poisonwood Bible. Through postcolonial critical study, this paper finds out that all these three works have some themes in common. First, these postcolonial works assume a shape of family saga which is parallel to the slow violence of ecological and psychological plundering of empires in the postcolonial countries. Second, like the mangroves which have a tenacious hold on life, these postcolonial people rather overcome the heterogenic challenge with the sturdy and tough mind than defeated. Third, the native people's ethics of earth functions as the stronghold for their respectable lifestyle in their indigenous historicity. Finally, as a big fat brother, the Americanized globalization or neoliberalism is warned as the neocolonialism which is often shown as the disguised pattern of greenwashing. Namely, the people's self-enhancement is always prior to the imperialistic development or neoliberalism in the postcolonial ecological texts which sharply contrast the native's life consciousness and the empire's development theory.

The aim of this study was to develop a Dietary Education Program focused on Slow Life (DEPSL) and verified its effectiveness in elementary school children using the extended Theory of Planned Behavior (TPB). The DEPSL was developed effectively according to the systematic program development model, ADDIE. The developed DEPSL was applied to the Education group (EDU), which was total of 130 students aged 12-13 in an elementary school by trained instructors for five weeks. The control group (CON) composed of 100 students of the same age was not given any dietary education. Pre- and post- questionnaires were collected from the students in both groups to compare the change in students' dietary life during educational intervention between EDU and CON. EDU showed significant positive effects in all extended TPB variables (p< .01), but CON showed a significant difference only in the 'knowledge' and 'behavior intention' (p< .05). In addition, the extended TPB model verified its conformity to determine if the effect of education leads to a change in the children's behavior. In conclusion, the DEPSL has a positive impacts on dietary life in school children. Nevertheless, further research will be needed to develop various and specialized dietary education programs with different level of grades in other school areas.

Objectives: To determine the actual revolutions per minute (rpm) values and compare the cyclic fatigue life of Reciproc (RPC, VDW GmbH), WaveOne (WO, Dentsply Maillefer), and TF Adaptive (TFA, Axis/SybronEndo) nickel-titanium (NiTi) file systems using high-speed camera. Materials and Methods: Twenty RPC R25 (25/0.08), 20 WO Primary (25/0.08), and 20 TFA ML 1 (25/0.08) files were employed in the present study. The cyclic fatigue tests were performed using a dynamic cyclic fatigue testing device, which has an artificial stainless steel canal with a $60^{\circ}$ angle of curvature and a 5-mm radius of curvature. The files were divided into 3 groups (group 1, RPC R25 [RPC]; group 2, WO Primary [WO]; group 3, TF Adaptive ML 1 [TFA]). All the instruments were rotated until fracture during the cyclic fatigue test and slow-motion videos were captured using high-speed camera. The number of cycles to failure (NCF) was calculated. The data were analyzed statistically using one-way analysis of variance (ANOVA, p < 0.05). Results: The slow-motion videos were indicated that rpm values of the RPC, WO, and TFA groups were 180, 210, and 425, respectively. RPC ($3,464.45{\pm}487.58$) and WO ($3,257.63{\pm}556.39$) groups had significantly longer cyclic fatigue life compared with TFA ($1,634.46{\pm}300.03$) group (p < 0.05). There was no significant difference in the mean length of the fractured fragments. Conclusions: Within the limitation of the present study, RPC and WO NiTi files showed significantly longer cyclic fatigue life than TFA NiTi file.

Global population is expected to reach nine billion in 2050 and the total demand for food is expected to increase approximately by 60 percent by 2050 as compared to 2005. Therefore, it is important to increase crop production in order to meet the global demand for food. Slow release fertilizers have been developed and designed in order to improve the efficiency of fertilizers. Mineral-based slow release fertilizers are useful because the minerals have a crystalline structure and are environmentally friendly in a soil. This review focuses on slow release fertilizers based on montmorillonite, zeolite, and layered double hydroxide phases as a host for nutrients, especially N. Urea was successfully stabilized in the interlayer space of montmorillonite by the formation of urea-Mg or Ca complex, $[(Urea)_6Mg\;or\;Ca]^{2+}$ protecting its rapid degradation in soils. Naturally occurring zeolites occluded with ammonium nitrate and potassium nitrate by molten salt treatment could be used as slow release fertilizer because the occlusion process increased the capacity of zeolites to store nutrients in addition to exchangeable cations. Additionally, surface-modified zeolites could also be used as slow release fertilizer because the modified surface showed high affinity for anionic nutrients such as nitrate and phosphate. Moreover, there were attempts to develop and use synthetic layered double hydroxide as a carrier of nitrate because it has positively charged layers which electrostatically bond nitrate anions. Kaolin was also tested by combining with a polymer or through the mechanical-chemical process for slow release of nutrients.

This study examines the correlation between the characteristics of sustainable slow design, The outcome derived from the pro-environmental consciousness in fashion design, and the trends of modern fashion design. The conclusion of this study is as follows. First, slow design for sustainability shows an environmental consciousness and stresses the ethical aspects of fashion design that take into account the wellbeing and sustainable development of human society. It also focuses on the continuos present in which the consistent pace of life endures, rather than pursuing speedy changes of fashion by titillating desire. Second, the five characteristics of slow design have been extracted from the analysis of the examples of fashion industry and other fashion-related areas. They are sustainability, recyclibility, handicraft, naturalness, and simplicity. Third, these characteristics of slow design have much to do with modern fashion genres. For instance, classical style fashions such as Chanel suit and Burberry coat have the same qualities of sustainability, while at the same time the Vintage fashion, which reinterprets the fashions from bygone eras in modern style, has the tendency of recyclibility, and the Hippie style, a resurrection of hand-touch spirit that emerged as a secondhand style expressionism resisting uniform mass production, has not only the quality of handicraft but also recyclibility.

Slow Bee Paralysis Virus (SBPV) is a pathogenic virus against honeybee and bumblebee, causes the death of adult bee by paralyzing the fore-leg of bee. In this study, for rapid detection of SBPV from bumblebee, SBPV-specific Ultra-rapid Reverse transcription PCR was developed. After optimizing of SBPV-specific Ultra-rapid PCR, the existence of $1.0{\times}10^8$ SBPV-specific DNA molecules could be recognized in 3 minute and 35 seconds. Even $1.0{\times}10^1$ molecules of SBPV-specific DNA could be measured with quantitative manner. Meanwhile, from both imported bumblebee and bumblebee produced in Korea, SBPV were detected using proposed method. In the laboratory as well as in the field, SBPV-specific Ultra-rapid Reverse transcription PCR would be applied and might be expected as useful tools at production of bumblebee or inspection for the import and export system of bumblebee.

Korean culinary culture is traditionally studied through the analysis of foods ingested. However, this study attempts to dialectically reinterpret Korean culinary culture through its relationship to Korean literature. In our study we consider culinary culture prior to the development of scientific techniques and economic growth related to food as "dietary lifestyle of the innocent world" and time since then as "the dietary lifestyle of the experience world". The former represents a simple means of survival without food processing (the "slow food" world), while the latter represents the "fast food" or processed food culture as a modern concept. People living in the age of economic growth and overflowing individualism have lacked an organic life and an opportunity to commune with nature. As a result, they have returned to values of the past, seeking the "slow food" culture to benefit their individual health. A series of return processes, however, were transformed into "the dietary life style of the higher innocence," called "a well-being dietary life style" involving a new healthy conception passing through the dietary life style of the experience world. Therefore, the purpose of this study is to investigate the dietary lifestyles of the "innocent" world and the "experience" world based on dialectic concepts. Individual concepts of "thesis" and "antithesis" are applied, as well as the developmental concept of "synthesis" for the way both symbolic worlds changed to "the dietary lifestyle of the higher innocence" and formed complementary relationships to each other.

This study was conducted to investigate the physiological characteristics and to isolate plasmid DNA of R. japonicum strains. The results obtained were as follows; Strains S117, S118, 005, 011 and DY-1 were slow-growers and showed alkaline reaction, whereas strains S110, S111, S114, S116, S120 and 010 were fast-growers and produced acid reaction in YEM broth. All the fast- and slow-growing R. japonicum showed gram negative and formed mucous white colony on agar plate. After 7 days, the colonies of the fast-growers were between 2.0 and 4.0mm in diameter, whereas those of slow-growers were approximately between 0.5 and 1.5mm. The fast-growers were uniformly sensitive to the pH of 4.5 and tolerant of the pH of 9.5, whereas the reverse was found for the slow-growers. All the fast-growers were able to grow in the presence of 2% NaCl however the slow-growers were not grown. All the microorganisms grew rapidly in simple mineral salt medium containing as the sole source of carbon. Starch was rarely utilized. All the fast-growers utilized sucrose. The slow-growing R. japonicum strains examined usually contained 1 to 3 plasmid DNA ranging between 15Kb and 250 Kb, whereas the fast-growing R. japonicum strains contained 1 to 3 plasmid DNA ranging from 20 Kb to 250Kb.

The purpose of this paper is to present a specific set of home teaching methods in hopes to prevent slow learner of the elementary mathematics. This paper deals with the number and operations, one of five topics in the elementary mathematics A survey of two hundred elementary school teachers was made to see the teacher's opinions of the role of home studying and to concretize the contents of the research topics. There were asked which is the most essential contents for the concrete loaming and which is the most difficult monad that might cause slow leaner. And those were found to be; counting, and arithmetic operations(addition and subtraction) of one or two-digit numbers and multiplication and their concepts representations and operations(addition and subtraction) of fractions. The home teaching methods are based on the situated learning about problem solving in real life situations and on the active teaming which induces children's participation in the process of teaching and learning. Those activities in teaching each contents are designed to deal with real objects and situations. Most teaching methods are presented in the order of school curriculum. To teach the concepts of numbers and the place value, useful activities using manipulative materials (Base ten blocks, Unifix, etc.) or real objects are also proposed. Natural number's operations such as addition, subtraction and multiplication are subdivided into small steps depending upon current curriculum, then for understanding of operational meaning and generalization, games and activities related to the calculation of changes are suggested. For fractions, this paper suggest 10 learning steps, say equivalent partition, fractional pattern, fractional size, relationship between the mixed fractions and the improper fraction, identifying fractions on the number line, 1 as a unit, discrete view point of fractions, comparison of fractional sizes, addition and subtraction, quantitative concepts. This research basically centers on the informal activities of kids under the real-life situation because such experiences are believed to be useful to prevent slow learner. All activities and learnings in this paper assume children's active participation and we believe that such active and informal learning would be more effective for learning transfer and generalization.
