Many agile practices have been suggested for software development flexible enough to adapt to a rapidly changing environment. However, too many agile practices hinder computer engineers from deciding which agile practices are suitable for a given project. They need guidelines of the benefits an agile practice provides for a project, and how many of its benefits are effective. Therefore, this study investigates IT experts' perspectives on each agile practice's effectiveness in their projects using a repertory grid technique. Based on an analysis of data collected from 23 Korean IT experts about 33 agile projects, we elicit 361 cognitive effects categorized into 30 benefits using content analysis. Next, we identify agile practices that are primarily used and recognized as positive and further examine what benefits many agile practices usually bring. Finally, we evaluate the level of benefits overall that each agile practice provides.

To develop a monitoring method for soil microbial communities in rice paddy fields, we used terminal restriction fragment length polymorphism (T-RFLP) to compare soil bacterial community structure in rice paddy fields experiencing different management practices: organic practices, conventional practices without a winter barley rotation, and conventional practices with a winter barley rotation. Restriction fragment length profiles from soils farmed using organic practices showed very different patterns from those from conventional practices with and without barley rotation. In principal component analyses, restriction fragment profiles in organic practice samples were clearly separated from those in conventional practice samples, while principal component analysis did not show a clear separation for soils farmed using conventional practices with and without barley rotation. The cluster analysis showed that the bacterial species compositions of soils under organic practices were significantly different from those under conventional practices at the 95% level, but soils under conventional practice with and without barley rotation did not significantly differ. Although the loadings from principal component analyses and the Ribosomal DNA Project II databases suggested candidate species important for soils under organic farming practices, it was very difficult to get detailed bacterial species information from terminal restriction fragment length polymorphism. Rank-abundance diagrams and diversity indices showed that restriction fragment peaks under organic farming showed high Pielou's Evenness Index and the reciprocal of Simpson Index suggesting high bacterial diversity in organically farmed soils.

Recent research on quality management systemically explored the use of quality management practices and performance. The consequences of using quality practices have not been consistently confirmed despite an increasing number of published empirical studies. The results of empirical studies of quality practices and performance are mixed. This study examines which quality management practices indicate high-, medium-, and low-performance under the TQM framework using MANOVA and multiple discriminant analysis (MDA). To measure quality management practices, this study used the Malcolm Baldrige National Quality Award (MBNQA) framework. Based on a survey of 490 suppliers from eleven different industries in Korea, the results revealed that the high performing group surpasses the medium and low performing groups in process management, employee empowerment, employee education and training, and employee satisfaction. Furthermore, the high and medium performing groups exceed the low performing group in human resource planning and evaluation, strategic deployment, leadership system, and senior executive leadership.

Purpose: This study investigated the practices of preventing infectious diseases by daycare center teachers. The focus was on the mediating effects of self-efficacy in the relationship between communication skills and practices of preventing infectious diseases. Methods: This study used a descriptive correlational design. The participants were 164 daycare center teachers. Hierarchical regression was used to test the mediating effect of self-efficacy in the relationship between communication skills and practices of preventing infectious diseases. Data were analyzed using the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and hierarchical regression. The mediation effect was analyzed using an SPSS Macro program, PROCESS. Results: Significant relationships were found between communication skills and practices of preventing infectious diseases (β=.19, p<.001), self-efficacy and practices of preventing infectious diseases (β=.59, p<.001), and communication skills and self-efficacy (β=.27, p<.001). Self-efficacy had a significant mediating effect (β=.17, 95% confidence interval=0.07~0.29) on practices of preventing infectious diseases. Conclusion: In order to improve practices of preventing infectious diseases among daycare teachers, it is necessary to develop and apply interventions and methods that can increase effective communication skills and self-efficacy.

Within the field of international adoption, little research has examined the involvement of fathers in cultural socialization practices. Using secondary data analysis with a sample of 332 international adoptive fathers and mothers, the present study examined international adoptive fathers' cultural socialization practices and compared these practices with those of international adoptive mothers. The results indicated that 1) family cultural socialization practices mainly engaged in by fathers were those that require little to no integration with people of the children's race and/or ethnicity, and 2) fathers' awareness or practices were found to be similar to those of mothers. This study illustrates the importance of continuing research on fathers' beliefs, attitudes, and practices in relation to the race and birth culture of their internationally adopted children.

The purpose of this current study was to examine the effects of nutrition and food safety management support by the Center for Children's Foodservice Management (CCFSM) in foodservice facilities for children in the Ulsan area. From December 2014 to July 2015, the status of nutrition practices and hygiene practices was assessed by dietitians using nutrition and hygiene practice checklists. The subjects of study were 48 institutional foodservice facilities for children. Some nutrition practice items showed significant increases in average scores of 'using CCFSM menus (P<0.001), revising menus (P<0.05), and reconfirm menus (P<0.01)' from pre-support to post-support. Regarding hygiene practices, some items between pre-support to post-support showed significant increases in average scores of 'having equipment for hand washing & disinfecting' (P<0.01), 'wearing disinfected clothing for kitchen hygienically' (P<0.05), 'proper sterilization' (P<0.05), 'recording the origin of ingredients' (P<0.01), 'use of different knives/cutting boards' (P<0.05), and 'an appropriate thawing process' (P<0.05) from pre-support to post-support. Based on the above results, we found that nutrition and hygiene management support by CCFSM in foodservice facilities for children had a positive influence on status of some nutrition and food safety practices.

This study investigated the relationships between parental child-rearing practices in early childhood and the perceived self-efficacy of college students. Subjects were 322 students attending 4-year universities. The sample was 66.1% female and had a mean age of 19.9 years. Research was conducted using questionnaires and descriptive analysis, correlation analysis, t-tests were used for data description and analysis. The major findings were as follows: 1) The difference between boys and girls in terms of parental child-rearing practices perceived by children was found. Girls perceived their parents’child-rearing practices as being more positive in early childhood than those of boys. 2) The difference between male and female students in terms of the level of the self efficacy was not found. 3) The difference between paternal and maternal child-rearing practices perceived by children was found. Children perceived maternal child-rearing practices as being more positive in early childhood than paternal child-rearing practices. 4) Parental child-rearing practices in early childhood was rebated to the self-efficacy of college students. Children who perceived their parents’child-rearing practices as being more positive in early childhood had a higher level of self-efficacy. The results support the importance of parental child-rearing practices in early childhood on the developmental pathways of children.

Objectives: This study aims to identify self-resilience factors that drive right dietary and food safety practices in middle school students. Methods: Data was collected from 438 middle school students in Daegu using a self-administered questionnaire in December, 2013. The questionnaire consisted of 81 items with the following categories: general information, self-resilience, right dietary and food safety practices. Statistical analyses to determine frequency, average, ANOVA, factor analysis, reliability analysis, and regression analysis were performed using SPSS 21. Results: The results of factor analysis indicated that self-resilience was classified into challenge, adaptability, patience and achievement needs, and right dietary practices were sub-grouped into family meals, experience of dietary life, eco-friendly, balanced food, economy and bad food control, and food safety practices consisted of management of bacteria, hand washing and eating off a plate, safety food and food purchasing. The score of right dietary and food safety practices showed significant differences by sex, grade, and school achievement (p < 0.05). The economy factor of right dietary practices was significantly affected by the management of bacteria (p < 0.001), hand washing and eating off a plate (p < 0.001), safety food (p < 0.01), food purchasing of food safety practices (p < 0.05). The challenge factor of self-resilience significantly affected family meals, experience of dietary life, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and safety food (p < 0.05). The adaptability factor of self-resilience was associated with factors such as eco-friendly, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and food purchasing (p < 0.05). Conclusions: This study suggests that dietary education programs for middle school students could incorporate food safety practices, and self-resilience such as challenge, adaptability, patience and achievement needs to be effective.

This primary purpose of this study was to analyze relations between child temperament and parental disciplinary practices. The subjects were 220 mothers and 220 fathers of kindergarten children. Child temperament was assessed using Colorado Childhood Temperament Inventory and parental disciplinary practices were measured by Parenting Scale. Resets indicated that (1) Fathers recognized their male children's temperament as more soothable and less emotional than those of female children whereas mothers recognized their male children's temperament as more active than those of female children. (2) Fathers recognized their children's temperament as more active than did mothers, but mothers recognized their children's temperament as more soothable than did fathers. (3) Children who were more sociable, less emotional, more sootable, and had longer attention span and persistence were related to more effective patemal disciplinary practices. (4) Children who were less emotional and had longer attention span and persistence were related to more effective maternal disciplinary practices. (5) Paternal disciplinary practices were explained by children's emotional temperament, whereas the best predictors of maternal disciplinary practices were children's emotional temperament and attention span and persistence.

The extent to which farmers use the recommended husbandry practices by farmers raising goats in southern Thailand was investigated. Base-line data was collected by interviewing 297 farmers and the constraints to the use of recommended husbandry practices were examined for these farmers in the Chana district, Songkhla province of southern Thailand. The number of farmers using the various recommended husbandry practices was low. An extension program is needed to encourage the use of recommended goat husbandry practices in target areas of southern Thailand to provide a better understanding of the most effective goat husbandry practices.
