Kindergarten Teacher’s Knowledge of Enterobiasis in Korea  [PDF]
Dong-Hee Kim, Hak-Sun Yu
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.44038
Abstract:

Previous reports have suggested that the environment of day care centres is a crucial factor in the development of enterobiasis. There is a lack of data regarding a teacher’s knowledge about enterobiasis although kindergarten teachers have the greatest influence on a child’s habits because the child spends a lot of time with them and because they manage the child’s physical environment. The focus of the present study was to evaluate the kindergarten teacher’s level of knowledge regarding enterobiasis. The cross-sectional survey is with 287 kindergarten teachers from 36 kindergartens in Korea. The level of knowledge regarding Enterobius vermicularis infection was measured using questionnaires. The percentage of correct answers to questions testing knowledge of enterobiasis ranged from 23.7 percent to 99.3 percent. The average score for the section on knowledge of enterobiasis was 7.85 (possible range: 0-12). The question enterobiasis occurs through contaminated water had the least correct answer rate (23.7%). The findings of this study suggest the need for increasing the kindergarten teacher’s knowledge regarding enterobiasis. Educational programs for kindergarten teachers will have a long-term impact on the prevalence of this infection.

Investigations on Structural Safety of Office Room Based on Fire Simulation and Transient Heat Transfer Analysis  [PDF]
Ah Young An, Eun Mi Ryu, Hee Sun Kim
World Journal of Engineering and Technology (WJET) , 2014, DOI: 10.4236/wjet.2014.23B004
Abstract:

This study aims at investigating heat propagations inside the structural members due to fire using fire simulation and transient heat transfer analysis. Toward that goal, fire simulation and transient heat transfer analysis for a 5-story building are carried out sequentially using Fire Dynamics Simulator (FDS) and ABAQUS 6.10-3, respectively. As results from fire simulation, temporal temperature information is obtained depending on various locations of the building, which is used as boundary condition for the structural elements generated in transient heat transfer analysis. Predictions from the transient heat transfer analysis show that the structural members are exposed spatially non-uniform temperatures which can cause significant eccentric deformation and aceleration of structural damages.

A response to Steubing et al., "Effects of systematic phonics instruction are practically significant": The origins of the National Reading Panel.
Gregory Camilli,Sun Hee Kim,Sadako Vargas
Education Policy Analysis Archives , 2008,
Abstract: A recent article by Stuebing, Barth, Cirino, Francis and Fletcher critiqued the findings of Camilli, Vargas, and Yurecko (2003) and Camilli, Wolfe, and Smith (2006). With a methodological argument, they attempted to resolve the conflict between these studies and the original report Teaching Children to Read (National Reading Panel, 2000). In response, it is argued that three issues must be considered in a fair assessment of the NRP report—program labels or bins, alternative bins, and the role of literacy activities in reading instruction. In this light, three hypotheses ventured by Stuebing et al. are analyzed. It is concluded that the argument by Stuebing et al. does not reveal flaws in the original NRP report by Camilli et al. (2003), though some points of agreement are acknowledged.

Health (Health) , 2018, DOI: 10.4236/health.2018.101011
Abstract: Measuring intrinsic hip external rotator strength (ER) without compensatory pelvic motion and activation of the sartorius is important for preventing or rehabilitating lower extremity injuries. However, the optimal method for measuring intrinsic hip ER muscle strength while minimizing compensatory pelvic motions and activation of the sartorius is unclear. The purpose of this study is to compare measurements of hip ER strength, compensatory pelvic motion, and sartorius activation in the sitting, prone, and sidelying positions. Thirty-one healthy subjects (16 males and 15 females) were recruited for this study. Hip ER strength, pelvic kinematics, and sartorius muscle activation were measured during maximal isometric contraction of the hip ER in the sitting, prone, and sidelying positions. Hip ER strength was measured using a load-cell-type strength-measurement sensor. Pelvic kinematics was measured using an electromagnetic motion-tracking sensor. Electromyography was used to measure sartorius muscle activity. Data were analyzed using one-way repeated-measures analysis of variance. The result showed that hip ER strength and sartorius muscle activation were significantly lower in the sidelying compared with the sitting and prone positions (p < 0.01). Pelvic anteroposterior tilting was significantly greater in the sitting compared with the prone and sidelying positions (p < 0.01). Pelvic rotation differed significantly among positions (p < 0.01). Pelvic lateral tilting was significantly greater in the prone compared with the sitting position (p < 0.017). Compensatory pelvic motion and sartorius muscle activation were lower when hip ER strength measurements were made in the sidelying position. Therefore, the sidelying position is effective for measuring selective intrinsic hip ER strength.
Efficient Text Extraction Algorithm Using Color Clustering for Language Translation in Mobile Phone  [PDF]

Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.32031
Abstract: Many Text Extraction methodologies have been proposed, but none of them are suitable to be part of a real system implemented on a device with low computational resources, either because their accuracy is insufficient, or because their performance is too slow. In this sense, we propose a Text Extraction algorithm for the context of language translation of scene text images with mobile phones, which is fast and accurate at the same time. The algorithm uses very efficient computations to calculate the Principal Color Components of a previously quantized image, and decides which ones are the main foreground-background colors, after which it extracts the text in the image. We have compared our algorithm with other algorithms using commercial OCR, achieving accuracy rates more than 12% higher, and performing two times faster. Also, our methodology is more robust against common degradations, such as uneven illumination, or blurring. Thus, we developed a very attractive system to accurately separate foreground and background from scene text images, working over low computational resources devices.

Hee Kyung Lim, Ha Young Song, Dal Rye Kim, Jeong Ho Ko, Sun Ah Lee, Kee-In Lee, In Taek Hwang
Advances in Chemical Engineering and Science (ACES) , 2015, DOI: 10.4236/aces.2015.51004
Abstract: An alternative path for the preparation of triacetylcellulose (TAC) from unrefined biomass Palm Empty Fruit Bunch (EFB) has been found with environmental benefits. The method comprises separation and regeneration of cellulose from lignocellulosic biomass dissolved in ionic liquid BMIMCl, and also modification of cellulose to TAC. The triacetylcellulose with a degree of substitution of 2.93 was obtained by the reaction of acetic anhydride at 55C with drastically reducing number of steps currently required to produce this derivative from raw materials itself. TAC was characterized using NMR analysis. The triacetate cellulose is typically used for the creation of fibers and film base.

International Journal of Mathematics and Mathematical Sciences , 2001, DOI: 10.1155/s0161171201006627
Abstract: We introduce a new notion, called a Q-algebra, which is a generalization of the idea of BCH/BCI/BCK-algebras and we generalize some theorems discussed in BCI-algebras. Moreover, we introduce the notion of “quadratic” Q-algebra, and show that every quadratic Q-algebra (X;∗,e), e∈X, has a product of the form x∗y=x−y

Sun Hee Kim,Hua Fei Lu,Conrad C. Alano
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0014731
Abstract: Sirtuins (Sirt), a family of nicotinamide adenine nucleotide (NAD) dependent deacetylases, are implicated in energy metabolism and life span. Among the known Sirt isoforms (Sirt1-7), Sirt3 was identified as a stress responsive deacetylase recently shown to play a role in protecting cells under stress conditions. Here, we demonstrated the presence of Sirt3 in neurons, and characterized the role of Sirt3 in neuron survival under NMDA-induced excitotoxicity.
A multilevel analysis of social capital and self-reported health: evidence from Seoul, South Korea

International Journal for Equity in Health , 2012, DOI: 10.1186/1475-9276-11-3
Abstract: We conducted a cross-sectional survey from December 2010 to April 2011 in Seoul, South Korea. The target population included respondents aged 25 years and older who have resided in the same administrative area since 2008. The final sample for this study consisted of 4,730 respondents within all 25 of Seoul's administrative areas.In our final model, individual-level social capital, including network sources (OR = 1.23; 95% CI = 1.11-1.37) and organizational participation (OR = 2.55; 95% CI = 2.11-3.08) was positively associated with good/very good health. Interestingly, the individual × area organizational participation cross-level interaction was negatively associated with good/very good health (OR = 0.40; 95% CI = 0.32-0.50), indicating that in areas with higher organizational participation, individuals with high organizational participation were less likely to report good/very good health when compared to low organizational participation individuals.Our study provides evidence that individual-level social capital is associated with self-reported health, even after controlling for both individual and area-level confounders. Although this study did not find significant relationships between area-level organizational participation and self-reported health, this study found the cross-level interaction for social capital. Hence, in areas with lower organizational participation, the probability of reporting good/very good health is higher for individuals with high organizational participation than individuals with low organizational participation. This study, albeit tentatively, suggests that policy makers should focus upon social capital when making policies which aim to enhance one's health.It has been widely acknowledged that places where people live are a crucial factor for individual health [1-3]. Previous studies have been focused on various physical aspects of places (e.g., environmental pollution) [4]. Other than these factors, there is a growing body of evidenc
