This study cheked on the general tendency of the value consciousness of working teenagers about family life and how it was affected by demographic and psycho-social variables. In that way modern korean family life making trouble with the traditional family relationship can comprefhensively be understood. And this study 500 copies of the questionnare were given to them and 478 copies were for use in the final information of analysis. Data was analyzed by frequency distribution percentage mean Pearson's product-moment correlation analysis and stepwise multiple regression analysis. The results are summarized as follows. 1) The value consciousness of working teenagers about family life shows a modern tendency on the whole 2) The value consciousness about family relationship comparatively shows a traditional tendency.

The purpose of this study was to explore a typology of leisure participation, investigate determinants of leisure participation types, and analyze differences in life satisfaction by the types of leisure participation of the elderly. The data source for this research was the 2014 Time Use Survey conducted by the Korea National Statistical office (KNSO). The statistical methods for the analysis were mean, standard deviation, ANOVA, Duncan test, cluster analysis, and logistic regression analysis. Leisure participation were classified into five types based on five categories; social activities, religious activities, media, sports, time-spending activity. The five types were named "general", "insufficient", "religious oriented", "media oriented", and sports oriented" type. Gender, health condition were identified as important determinants for the types. Life satisfaction was different according to leisure participation type of the elderly. Religious oriented type showed the highest score of life satisfaction and media oriented type showed the lowest.

Fracture analysis and remaining life prediction has been carried out for aluminium alloy (Al 2014A) plate panels with concentric stiffener by varying sizes and positions under fatigue loading. Tension coupon tests and compact tension tests on 2014A have been carried out to evaluate mechanical properties and crack growth constants. Domain integral technique has been used to compute the Stress intensity factor (SIF) for various cases. Generalized empirical expressions for SIF have been derived for various positions of stiffener and size. From the study, it can be concluded that the remaining life for stiffened panel for particular size and position can be estimated by knowing the remaining life of corresponding unstiffened panel.

In this paper, we investigate the various opportunities of women informatization, which we believe to be major contributors for the high quality of life for women. We first justify various efforts for women informatization, which needs to be based on the analysis of the problems and the status quo. We have also examined the related government policies and programs as well as the programs of non-profit organizations for woman, and identified key problems areas. Integrating the results from this analysis, we have developed the vision and the framework for women informatization. We also give a list of strategic alternatives for improving quality of life through informatization, and promoting full-time housewives to become aggressive information users, information producers and information specialists. We use the expert Delphi method and fish-bone chart analysis to generate the priorities of specific tasks and target-based strategies for successful implementation of women informatization. We conclude this paper with various recommendations for empowering women to enjoy high-quality living through the process of informatization.

This paper presents about the analysis on cost factor reduction using the life cycle cost model for motor block in the KTX-1. Until now, most life cycle cost of the system as a whole that has been studied. but in case of railway industry part, LCC studies are needed on the subsystem like a propulsion control system because subsystems are developed continuously localization. Therefore, In this paper presents cost breakdown structure for life cycle cost (LCC) estimation for localization development of propulsion control system (Motor Block) in high speed railway vehicle (KTX-1). Also to analysis LCC on motor block, it was analyzed physical breakdown structure (PBS) and preventive cost on propulsion control system in view of maintenance cost. Based on this, we describe life cycle cost on motor block of KTX-1.

Power transformers are the most important facilities in the substation of electrical power, yet they do not have the efficient operating life characteristics which are the important elements of repairing and maintenance in regional conditions. This paper describes the statistical analysis of operating conditions and troubles on transformers for the operating life assessment using Statistical Analysis System programs, Hazard method and Weibull distributions. We analyze transformers in several methods, and compares correlation relationship of operating life and troubles. Therefore, this study will be the useful basic operating life prediction technique of power transformers in the future.

The purpose of this study was to identify the preference of interior design, design style and color, according to consumers' life style. Data were collected from March 7th. 2002. to March 22nd. 2002 using the questionnaire. The subjects were 228 adults and frequency, percentage, mean, cross tab, F-test, factor analysis, and cluster analysis were used for data analysis. The major results of this study were: 1) The types of life style were 3: regular family oriented type, progressive fashionable type, and conservative self-manageable type. 2) This study revealed relative difference in design style and color preference according to consumers' life style. Therefore, the type of life style could be used as powerful variable in interior design and marketing of allied industries.

The assemblies of our partial genomic sequence data of Sphingomonas chungbukensis DJ77, with the total size of 877,928 bp, was done by TIGR Assembler. The total size of our current obtained contigs was about 0.73 Mb. A comparative genome analysis between our uncompleted genome and the other completed genomes was performed by taking advantage of the availability of multiple complete genomes in COGs database (Clusters of Orthologous Groups of proteins) to produce the genomic prediction of our S. chungbukensis DJ77. This analysis based on homologues search among completed genomes provides good initial step to our better assigning putative function to predicted coding sequences.

The purpose of this study was to determine the effect of expansion joint spacing (slab size) on the life cycle costs of owning Portland Cement Concrete (PCC) airfield pavements. Previous research has shown that slab size has a statistically significant impact on pavement performance. A probabilistic life cycle cost analysis was performed to determine if the effect of slab size on pavement performance would affect the total cost of ownership of PCC pavements. Data from 48 Pavement Condition Index (PCI) inspections of military and civilian airfields were used to develop probability-of-distress-by-condition curves, which were then used to develop probabilistic cost-of-repair-by-condition curves. A present worth life cycle cost analysis was then performed for various slab sizes, using construction costs, rehabilitation costs, and maintenance costs. Maintenance costs were determined by assuming a condition deterioration rate appropriate for each slab size and applying the cost-by-condition curves. The probabilistic cost-of-repair-by-condition curves indicated that smaller slabs are more expensive to repair on a unit cost basis. Life cycle cost analysis showed that larger slabs have a higher total cost of ownership than smaller slabs due to a faster rate of deterioration.

Venturia nashicola is a fungal pathogen causing scab disease in Asian pears. It is particularly important in the Northeast Asia region where Asian pears are intensively grown. Venturia nashicola causes disease in Asian pear but not in European pear. Due to the highly restricted host range of Venturia nashicola, it is hypothesized that the small secreted proteins deployed by the pathogen are responsible for the host determination. Here we report the whole genome based phylogenetic analysis and predicted secretomes for V. nashicola isolates. We believe that our data will provide a valuable information for further validation and functional characterization of host determinants in V. nashicola.
