This study examines household expenditure patterns for single-parent families to better understand the decision-making process and to consider the appropriateness of the decisions on monetary allocation. This study investigates the household expenditure patterns and the determinants of expenditure patterns for single-father families as compared to those for single-mother families. A series of analyses of the data, which was gathered from the 2015 Single-parent Family Survey on household expenditures, were conducted. The results show that there are differences in the household expenditure volumes and patterns between single-father families and single-mother families. Differences in the categories of expenditure and variations in the share that was allocated for each expenditure category in single-father families as compared to in single-mother families were both statistically significant. Disparities were found in seven categories of household expenditure between single-father families and single-mother families. The amount allocated from total expenditures for each expenditure category was also significantly different between single-father families and single-mother families in regards to clothing, home equipment, housing, water/light/heat costs, transportation, and telecommunication. The determinants of the total household expenditure for single-parent families were age, level of education, number of family members, public transfer, household income, assets, and debt.

A new product development is critical to the growth and success of most business firms. Increasingly, the new product development is recognized as an essential component of the corporate plan. But, relatively few research investigations have focused on the elements of a new product development strategy and its performance results. This study aims to identify the patterns of new product development strategy which business firms adopt, and its performance results. To identify these patterns and results, 268 firms in four industries known to be active in new product development were selected as a matter of convenience, and surveyed by the questionnaire and interviews. The questionnaire is composed of 67 strategy variables, 8 performance variables, and other variables. To analyze the data from samples, various statistical methods such as factor analysis, Pearson correlation analysis, sluster analysis, and one-way ANOVA were employed. This analysis brought forth the following major findings: First, three new product development strategy patterns were identified. Each strategy pattern was proved to be different from the others in terms of group of strategy elements that were adopted. Second, the new product development strategy was closely linked to its performance. Third, the difference of performance results among strategy groups in each industries was rather significant, however, the performance difference among industries in each strategy group was less significant.

The purpose of this study is to offer suggestions to help immigrated youths of multicultural families become successful members of Korean society while preparing to enter schools or becoming involved in social activities. The study examined the following three issues using grounded theory: (1) the characteristics of cultural adaptation for immigrated youths of multi-cultural families; (2) their acculturation processes; and (3) their different patterns of acculturation experience. The process of acculturation involves (1) feeling timid, (2) feeling regretful and angry, (3) looking around and making an attempt, (4) feeling difficulty and feeling left out, (5) accepting reality and seeing Korea in a positive light. The core of acculturation among the immigrated youths of multicultural families is a limited living in an unfamiliar culture. Five acculturation patterns were found in the current study: (1) Someone who is actively striving for future dreams; (2) someone who adjusts himself/herself to circumstances without plans; (3) someone who passively makes an effort; (4) someone who accepts reality to continue education; and (5) someone who temporarily stays for financial reasons.

The research developes short-run standardized control charts(SSCC) and short-run acceptance control charts(SACC) under the various demand patterns. The demand patterns considered in this paper are three types such as high-variety and repetitive low-volume pattern, extremely-high-variety and nonrepetitive low-volume pattern, and high-variety and extremely-low-volume pattern. The short-run standardized control charts developed by extending the long-run ${\bar{x}}$-R, ${\bar{x}}$-s and I-MR charts have strengths for practioners to understand and use easily. Moreover, the short-range acceptance control charts developed in the study can be efficiently used through combining the functions of the inspection and control chart. The weighting schemes such as Shewhart, moving average (MA) and exponentially weighted moving average (EWMA) can be considered by the reliability of data sets. The two types according to the use of control chart are presented in the short-range standardized charts and acceptance control charts. Finally, process capability index(PCI) and process performance index(PPI) classified by the demand patterns are presented.

This study determined the influence of personality patterns on marital adjustments mediated by communication effectiveness for 298 international marriages in South Korea. The results are as follows: (a) The mediator effects of personality patterns and communication effectiveness on the marital adjustment of international marriages were found to be significant; in addition, a mediator path with marital adjustment as a dependent variable was verified. (b) The extroversion, agreeableness, and openness of husbands were found to have a positive effect on their communication and marital adjustment in regards to the personality patterns of international. (c) Conscientiousness was identified as the only factor that affects the marital adjustment of a wife in regards to personality patterns. The implications of this study will be discussed in the conclusion part.

In this paper, multiplhase only filter(MPOFs) are designed using simulated annealing algorithm. These filters have excellent recognition characteristics for similar patterns or rotated patterns and enhance optical efficiency as well as spatial-bandwidth product by deleting mirror image. As the result of computer simulation to certify recogntion characteristics of similar patterns, simulated annealing-MPOF(SA-MPOF) has superior discrimination and higher correlation peak values than cosine binary phase only filters(CBPOF) and simpulated annealing-BPOF (SA-BPOF). THe filter having training process for rotated patterns of arbitraty possible angle can overcome that phase only filter(POF) and CBPOF can't recognize rotated input patterns.

The present study investigated the sleep patterns 1-to 3-year-old children and examined whether their sleep patterns would predict their early adjustment to daycare centers. The participants were 239 young children attending daycare centers in Seoul. The data on children's sleep patterns were collected by parent report. Children's adjustment to daycare was assessed by daycare providers' reports. The data were analyzed by means of Chi-square test, t-test, Pearson's correlation, ANOVA and discriminant analysis. The results were as follows: Children from dual-earner families had shorter nocturnal sleep duration than those from single-earner families. There was no significant relation between daytime sleep duration and sleep-onset time at night. It was found that children who go to bed earlier were more likely to get sufficient sleep without nocturnal wakefulness. Age and total sleep duration were seen to be significant variables when it came to discriminating between the adjustment versus maladjustment groups.
