The purpose of this study was to investigate the effect of household characteristics on household expenditures on wedding, funeral, ancestor worship, and 60th birthday anniversary. Data for this study were from the 1996 Annual Report on the Family Income and Expenditure Survey. OLS regression analysis was used to identify the effect of household characteristics on money spent on family ceremony expenditures. The household income, age of head, education of head, and family size were all significant factors for understanding family ceremony expenditures. The results also indicated that additional income from wife's labor force participation was associated with lesser expenditures on family ceremony, while business income, asset income, and transfer income had no effects on this category. The effect of the third quarter of 1996 was significant on family ceremony expenditures, indication that households spent significantly less for this category in the summer than did in the winter, holding other factors constant.

For an odd prime p and integer n, m and k such that n=(2m＋1)ㆍk, a new family of p-ary sequences of period p$^{n}$ -1 with optimal correlation property is constructed using the p-ary Helleseth-Gong sequences with ideal autocorrelation, where the size of the sequence family is p$^{n}$ . That is, the maximum nontrivial correlation value R$_{max}$ of all pairs of distinct sequences in the family does not exceed p$^{n}$ 2/ ＋1, which means the optimal correlation property in terms of Welch's lower bound. It is also derived that the linear span of the sequences in the family is (m＋2)ㆍn except for the m-sequence in the family.

Internalizing and externalizing behavior problems may be more common in children with disability families but rarely known is the magnitude of the problem and the risk factors compared to those in children with non-disability families. This study was undertaken to examine if socio-economic factors, parental health, and family functioning affect children's internalizing and externalizing behaviors differently between two comparison groups. The research literature on childhood behaviors was briefly reviewed. The data was derived from the Mental Health of Children and Young People in Great Britain, 2004. Regression analyses provide evidence that the family type, economic status, and income level are uniquely associated with an increased risks of internalizing or externalizing behavior problems in children with disability families, whereas sex, age, family size, parental health, and family functioning factors have similar impacts on the child's internalizing or externalizing variances between two groups. Intervention is desirable to address the concerns influencing internalizing and externalizing performances among children with disability or non-disability families.

The purpose of the study was to analyze the family structure in rural Korea systematically and comprehensively according to the broad concept. The data was collected from 810 rural households by interview method with questionnaire. For the analysis, family structure was divided into aspects of static structure and dynamic structure. The static structure was constructed by two components of demographic structure and typological structure. The dynamic structure was also constructed by three components of decision making structure, role structure, and dynamic relationship structure of family members. In demographic structure, family size was 4.1 persons, families, with more female were 35.2%, and families with elder husband than wife were 82.5%, In the typological structure, nuclear family type with two-generation was predominant. In dynamic structure, role structure was autonomic type while conjugal power structure was compounded type with autonomic, syncratic, and husband-dominant type.

The purpose of this study was to explore the degree of the stress from the family resources management according to objective resources and to investigate the relative importance of the variables which affect the stress from the family resources management in housewives. The subjects of this study were 565 married women who lived in apartment in Taegu. A questionnaire was used as survey method. The data was analyzed by means of factor analysis, t-test, ANOVA, Scheffe test and multiple regression analysis. The main findings were as follows First there was significant difference in the degree of the stress from the family resources management according to the objective resource. Second, the stress from the family resources management were more affected by perceived adequacy resource, the passive coping style, size of apartment than other variables.

The purpose of this article is, first, to argue that the fertility cannot be reduced rapidly through widerspread diffusion of contraceptive practices which has been the main drive of the national policy in population control, because there involves the inescapable externalites in procreation, second, family sizes tend to be larger because of the financial externalities arising from government subsidies to families with children, and finally, the decreasing relative risk aversion of households with wealth may induce the poor to have large family sizes.

A new marine sponge in the family Tethyidae, Tethya uljinensis n. sp. was collected from Uljin, Korea in 2007. Halicometes koreana in the family Tethyidae was redescribed. Tethya uljiensis n. sp. is closely to Tethya simi. in skeletal structure and spicule composition. But, it differs in the size of spicules(stronyloxea) and shape of oxyaster.

The purpose of this study is to understand the factors that influence residents' satisfaction with their housing. Resident's satisfaction is mainly influenced by two factors - one that pertains to housing and the other as per characteristics of the individual. Housing-related factors include housing types, housing tenure types, and size of floor space. Individual-related factors include household income, size, and education level. This study shows how both factors influence residents' satisfaction. Residential satisfaction is affected by the type of housing tenure (own, chonsei and monthly rent) and housing (detached housing, apartment and multi-family housing). Residential satisfaction of home owners is greater than that of chonsei renters or monthly renters. Residential satisfaction of chonsei renters is greater than that of monthly renters. Satisfaction of apartment residents is far greater than that of detached housing residents or multi-family housing residents. There is no difference in residential satisfaction between detached housing and multi-family housing residents. As total household labor income, household member, and residential area increase, residential satisfaction increase. Residential satisfaction of countryside residents is greater than that of metropolitan residents.

New family of frequency hopping patterns with long period and good Hamming autocorrelation and Hamming crosscorrelation properties which can be used for frequency hopped multiple access communication systems is introduced. Period of frequency hopping patterns is qk-1, the alphabet size of frequency hopping patterns is q, and the size of family of frequency hopping patterns is q, where k is arbitrary integer and q is power of prime number. The maximum value of out-of-Phase Hamming autocorrelation function of any frequency hopping pattern and Hamming crosscorrelation function of any two frequency hopping patterns in the family is qk-1, which corresponds to optima1 Hamming correlation properties. And the average number of hits per q*q square in one frequency hopping pattern and its time shifted version or two frequency hopping patterns in the frequency hopped multiple access communication systems is less than 1.

This study has been performed to analyze size and deficit problem of residential space in later life. In this study, 216 Koreans aged 50 to 79 were surveyed for their current residential space ad family related items such as age, marital status, living arrangement, birth order, and housing status. The results are drawn as follows: 1. The space size significantly fluctuates by marital status, number of generations living together, tenure, and structure type; For example, use of indoor area per person ranges from 7.01 pyoung for three-generation households to 19.53 for one-generation households. 2. s for space deficit, very old widowed females, 60's living in rented or multi-family housing units, and those living in three generations are high risk groups of the space deficit below 7 young per person. In this study, further researches are recommended as follows; Regarding the highest risk group of space deficit, life styles causing space-related conflicts should be studied, and accordingly proper welfare services for the causal life styles be offered. Housing maintenance & utility costs be investigated and guidelines should be proposed for any surplus groups among the 60's, so that their space surplus can be reduced by suitable adjustment process.
