  • The purpose of this study was to explore to what extent mothers and fathers differ in their disciplinary practices and to examine the relationships between quality of life and the parental disciplinary practices. The subjects of this study consisted of 220 parents(220 mothers and 220 fathers) of 5-6 years of children in Pusan. Descriptive analysis, correlation analysis, t-tests were used for data description and analysis. The major results were as follows: 1. There was a positive relationship between perceived quality of life by fathers and perceived quality of life by mothers. 2. There was a difference between fathers and mothers in relation to perceived quality of life. Fathers perceived their quality of life more highly than did mothers. 3. There were positive relations between parental educational level, household income and quality of life. 4. There were differences between fathers and mothers in relation to disciplinary practices. Fathers exhibited more effective disciplinary practices(including less overreactiveness and less verbosity) than did mothers. 5. There were no relations between parental educational level and disciplinary practices, but household income was only related to maternal disciplinary practices. 6. There were positive relations between quality of life and disciplinary practices. The higher parents perceived their quality of life, the more parents exhibited effective parental disciplinary practices.

  • This study deals with the petrographic examination of aggregates(ASTM C 295) which is one of the methods to diagnose the quality of aggregates for concrete artifacts. A number of examinations including size and sieve analysis, test on the coating material, description of the weathering and contamination condition, petrographic description, and qualitative and quantitative analyses on the rocks and minerals potential to alkali-aggregates reactivity are carried out to examine the quality of aggregates. Petrographic description method examined on the fluvial aggregates from Maewhacheon A, B area, Uljin-gun, Kyungnam province shows that weathering grade ranges from F(fresh) to WS(slightly weathered) and coating material and contamination are not in a harmful condition. The weight percentage of the alkali-aggregates reactive minerals or structurally unstable rocks of the aggregates from study area covers 26% and 19% of all aggregates, respectively. So it is necessary to further identify their quality through the chemical(ASTM C 289) and mortar-bar method (ASTM C 227).

  • The purpose of this study was to standardize ingredients used by school foodservices. This study analyzed the current notation of ingredients in used by used in school foodservices through the NEIS system employed by school foodservices of elementary schools through high schools in South Korea. Specifically, this study suggests systemized standardization of ingredient classification and quality attributes of at school foodservices by applying a case study analysis. The findings from the case analysis of the Electronic Procurement System operator are as follows. Classifications for ingredients of the NEIS system used by school food services consisted of included food group, food name, detailed food name, and description. Classification was not clearly divided between the classification scheme and the attribute system. Therefore, food group, food name, and product information of each food should be categorized as the classification scheme, whereas the detailed food name (excluding product information) and description should be standardized as the attribute system, which is composed of required attributes, recommended attributes, and other attributes. This study suggests that system standardization should be carried out in the field of school foodservices, as advancements between distributors and school food service providers could affect food ingredient quality. Thus, standardization can influence purchase and distribution in many ways.

  • Korean auxiliary verbs are often used in Korean sentences in spite of the small number of the auxiliary verbs, However. the incorrect processing of the verbs concept leads to the poor translation quality. To solve the problems of the auxiliary verb processing. the paper proposes a description of the auxiliary verbs based on Conceptual Graph (CG), For the description of the auxiliary verbs within CG. we first collect 40 Korean auxiliary verbs and example sentences from papers and a Korean dictionary, Next, we perform the analysis of the Korean auxiliary verbs through a classification: perfective, progressive, benefactive, attemptive, emphatic, desirable, retentive, and presumptive. Then we depict the eight meanings based on CG. In the experiment. the paper implements the program that translates sentences included in the auxiliary verbs into CG and explains the experimental results.

  • The quality characteristics and antioxidant activity of Tteokbokkidduk alone or supplemented with 3%, 6%, 9%, and 12% wheat bran powder were assessed, to increase use of the wheat bran by-product of wheat milling. The moisture content, pH, and starch elution of Tteokbokkidduk increased with increasing wheat bran powder, while the water absorption rate did not. The L color value decreased and the a and b values increased with increasing wheat bran powder. Scanning electron microscopy of Tteokbokkidduk prepared with 0% and 3% wheat bran powder revealed uniform pore size distribution. In terms of texture profile analysis, hardness and chewiness increased, while cohesiveness decreased with increased content of wheat bran powder. Acceptance was highest for samples with 6% wheat bran powder. Quantitative description analysis (QDA) revealed increased brownness, roughness, nutty, bitterness, astringency, savory character, and hardness, and decreased adhesiveness, springiness, and chewiness with increased wheat bran powder. Principal component analysis (PCA) revealed highest overall acceptance of samples prepared with 6% wheat bran powder, reflecting the relatively low values of detrimental sensory characteristics. Antioxidant activities of Tteokbokkidduk increased as wheat bran powder content increased. The addition of 6% wheat bran powder resulted in excellent Tteokbokki in terms of acceptance, quality, and antioxidant activity.

  • In this paper, we conducted an empirical study to investigate whether Android app descriptions provide enough permission usages for measuring app quality in terms of human writing and consistency between code and descriptions. Android app descriptions are analyzed for various purposes such as quality measurement, functionality recommendation, and malware detection. However, many app descriptions do not disclose permission usages, whether accidentally or on purpose. Most importantly, the previous studies could not precisely analyze app descriptions if permission usages cannot be completely introduced in app descriptions. To assess the consistency between permissions and app descriptions, we implemented a state-of-the-art method to predict Android permissions for 29,270 app descriptions. As a result, 25% of app descriptions may not contain any permission semantic, and 57% of app descriptions cannot accurately reflect permission usages.

  • Gradually, there has been increase in the use of qualitative research methods in nursing research. Nursing scholars are using qualitative research methods to explore the essence of nursing and discover its meaning. However, there has been lack of standards for evaluating qualitative nursing research. Often nursing researchers are applying quantitative research evaluation standards to qualitative nursing research. Thus, there has not been any notable qualitative research done to date. In order to improve the quality of nursing research done to discover new knowledge for the nursing, & for development of nursing theory, criteria for critiquing qualitative research should be established. Therefore, this researcher introduced standards as criteria for critiquing qualitative research which are based on literature reviews and re search experiences. The suggested criteria are developed several question's as follows : 1) description of the research phenomena, 2) significance, 3) research purpose, 4) research question, 5) assumptions, 6) researcher's abilities, 7) selection of research samples, 8) data collection, 9) human subjects, 10) data analysis, 11) description of researcher's results, 12) literature review. Follow-up of concrete questions for each of the criterias have been developed.

  • The finite element mesh approach for tool surface description is applied effectively to analyze sheet metal stamping processes. To improve the mesh quality and the stability of the mesh generation process, a gybrid method based on the grid approach and the Delaunay triangulation is proposed in the present work. In the present study, a general method for the mathematical description of arbitrarily shaped tool surface is proposed by introducing the parametric surface approach. A polynomial function employed to describe the base parametric surface and the boundary curves are defined to describe arbitrary three-dimensional trimmed surfaces. To verify the validity of the proposed method, automatic mesh generation is carried out for some shosen complicated parts including actual automotive panel.

  • In this paper, power quality analysis system is proposed where voltage or current waveforms are nonsinusoidal. The proposed system relies on the FFT algorithm to compute real and reactive power. The advantage of system is that harmonic analysis is carried out on a period of the input signal. The proposed system is based on FFT processor which is designed using VHDL(Very high-speed integrated circuit Hardware Description Language). In the design of FFT processor, radix- $2^2$ is adopted to reduce several complex multipliers for twiddle factor. Complex multiplier is implemented as only shifters and adders. Therefore, the system is able to have both high hardware efficiency and high performance.

  • Purpose: The aim of this study was to develop and to analyze the task of gerontological nurse practitioners (GNPs) in Korea. Methods: The definition of GNP and job description was developed based on developing a curriculum (DACUM) by 7 panels who have experienced in DACUM analysis and gerontological nursing. One hundred sixty nurses who were working at long term care facilities were participated. The questionnaire included frequency, importance, and difficulty of duties, tasks, and task elements. The data were collected in November 2006, analyzed by descriptive statistics. Results: The job description of GNPs in Korea revealed 5 duties, 23 tasks, and 86 task elements. On the all five duties, the highest duty in frequency and in importance was professional nursing care ($3.25{\pm}0.35$, $3.49{\pm}0.29$). But the highest duty in difficulty was research ($3.24{\pm}0.46$). 'Prevent health problem ($3.42{\pm}0.43$, $3.56{\pm}0.33$)', 'Teach other staffs ($2.83{\pm}0.77$, $3.39{\pm}0.43$)', 'Develop the evidence-based standards ($2.43{\pm}0.76$, $3.22{\pm}0.43$)', 'Develop the self ($2.81{\pm}0.65$, $3.26{\pm}0.42$)', and 'Participate the team activities' were the highest score in frequency and in criticality of tasks. 'Provide emotional support to older adults and families ($3.16{\pm}0.41$)', 'Counsel older adults and their families ($3.14{\pm}0.49$)', 'Do clinical research ($3.32{\pm}0.49$)', 'Quality insurance ($3.25{\pm}0.49$)', and 'Build collaborative system ($3.18{\pm}0.47$)' were perceived the most difficult tasks. Conclusion: The political efforts for the legislation of role and task of GNPs were needed.
