Acetoin (AC) is a volatile platform compound with various potential industrial applications. AC contains two stereoisomeric forms: (3S)-AC and (3R)-AC. Optically pure AC is an important potential intermediate and widely used as a precursor to synthesize novel optically active materials. In this study, chiral (3R)-AC production from meso-2,3-butanediol (meso-2,3-BD) was obtained using recombinant Escherichia coli cells co-expressing meso-2,3-butanediol dehydrogenase (meso-2,3-BDH), NADH oxidase (NOX), and hemoglobin protein (VHB) from Serratia sp. T241, Lactobacillus brevis, and Vitreoscilla, respectively. The new biocatalyst of E. coli/pET-mbdh-nox-vgb was developed and the bioconversion conditions were optimized. Under the optimal conditions, 86.74 g/l of (3R)-AC with the productivity of 3.61 g/l/h and the stereoisomeric purity of 97.89% was achieved from 93.73 g/l meso-2,3-BD using the whole-cell biocatalyst. The yield and productivity were new records for (3R)-AC production. The results exhibit the industrial potential for (3R)-AC production via whole-cell biocatalysis.

The purpose of this study is to investigate mothers' beliefs regarding children's literacy development and self-reported home literacy practices with their children. The instrument used for this study measured mothers' beliefs toward the whole language approach against the traditional approaches in children's literacy development. The total number of 340 mothers participated in this study who are sending their children to daycare centers of kindergartens in Seoul and its suburban area. Mean, Standard Deviation, frequency, Spearman's rho, and Kendall's tau were employed to analyze the data. The results showed that mothers' beliefs on the whole language approach have relationships with their home literacy practices, and their demographic characteristics - such as mothers' education, their spouses' education, and income - were also related with mothers' beliefs. The results of this study explore the inter-relationship of mothers' beliefs with home literacy practices, and also the importance of mothers' belief system on children's literacy learning at home.

This study compared levels of whole grain consumption-related predisposing, reinforcing, and enabling factors according to socio-demographic variables, and examined how these factors are associated with whole grain consumption frequency among Korean adults. A survey questionnaire was administered to a convenience sample of adult males and females aged 20~59 years (n=300). The questionnaire included questions on predisposing, reinforcing, and enabling factors in relation to whole grain consumption as well as a brief whole grain food frequency questionnaire. Female subjects showed a significantly higher level of negative beliefs on health nutrition taste texture while showing a significantly lower level of social support compared to that of males. The age group of 40~59 years showed a significantly higher social support level than the age group of 20~39 years. Results from multivariate regression analyses showed that different combinations of predisposing, reinforcing, and enabling variables were significant in predicting whole grain consumption frequency according to sex and age. The study findings can be used for developing specific target-oriented nutrition intervention programs for promotion of whole grain intake among Korean adults.

Objective: During the physical therapy education, if we can understand the student's attitude then we can make valuable suggestions with respect to the teaching in the universities and professional employment in the country. The aim of the current study is to develop a questionnaire to test the physical therapy students' attitudes towards their education and profession and to test its test-retest reliability and content validity. Design: Cross-sectional study. Methods: A total of 47 physical therapy students who were in their final year were randomly selected to participate in the study. After the making of the questionnaire, it was given to 6 professional experts teaching in the field of physical therapy to obtain their responses for each question with a 5-point Likert scale grading. Their answers were used in making the content validity of the questionnaire. Afterwards, the physical therapy students were asked to fill the questionnaire. Instrument reliability and test-retest reliability were also assessed by having the students complete the questionnaire after one month of taking the questionnaire. Results: The content validity index was 0.71 for the whole scale and values of individual subdivisions were ranging from 0.69 to 0.75. Instrument reliability measured by Cronbach's alpha coefficient was 0.86 for the whole scale and subdivision values were ranging from 0.32 to 0.86. Test-retest reliability was assessed by intraclass correlation coefficient, which was 0.71 for whole scales and subdivision values were ranging from 0.38 to 0.70. Conclusions: This questionnaire, which assesses the physical therapy student attitude towards their education and profession, has good content validity, instrument reliability, and test-retest reliability.

Given the importance of algebra in the early grades, this paper analyzed the contents of whole numbers and their operations from the perspectives of generalized arithmetic. In particular, the focus of analysis was given to the properties of 0 and 1, those of operations such as commutativity, associativity, and distributivity, and the relations between operations. As such, this paper analyzed in detail how such properties and relations were introduced and expanded across different grades. It is expected that many issues in this paper will serve basic information to develop instructional materials in a way to fostering students' algebraic thinking in the elementary grades.

Background: During hot environment work tasks with whole-body enclosed anti-bioaerosol suit, the combined effect of heavy sweating and exhaled hot humid air may cause the N95 medical respirator to saturate with water/sweat (i.e., water-blocking). Methods: 32 young male subjects with different body mass indexes (BMI) in whole-body protection (N95 medical respirator + one-piece protective suit + head covering + protective face screen + gloves + shoe covers) were asked to simulate waste collecting from each isolated room in a seven-story building at 27-28℃, and the weight, inhalation resistance (R_f), and aerosol penetration of the respirator before worn and after water-blocking were analyzed. Results: All subjects reported water-blocking asphyxia of the N95 respirators within 36-67 min of the task. When water-blocking occurred, the R_f and 10-200 nm total aerosol penetration (P_t) of the respirators reached up to 1270-1810 Pa and 17.3-23.3%, respectively, which were 10 and 8 times of that before wearing. The most penetration particle size of the respirators increased from 49-65 nm before worn to 115-154 nm under water-blocking condition, and the corresponding maximum size-dependent aerosol penetration increased from 2.5-3.5% to 20-27%. With the increase of BMI, the water-blocking occurrence time firstly increased then reduced, while the R_f, P_t, and absorbed water all increased significantly. Conclusions: This study reveals respirator water-blocking and its serious negative impacts on respiratory protection. When performing moderate-to-high-load tasks with whole-body protection in a hot environment, it is recommended that respirator be replaced with a new one at least every hour to avoid water-blocking asphyxia.
