The purpose of this study was to examine a path model that investigated the relations among socioeconomic variables. financial management and financial satisfaction of urban households. for this purpose conceptual framework based on the system theory of family resource management was suggested. Data were collected from questionaire with 254 financial managers who were residents of Seoul. The major findings of this study were as follows: (1) The variables that effected financial satisfaction directly ere financial knowledge monthly saving amounts the gap between the level and standard of living and financial implementing. The financial planning effected indirectly on financial satsfaction through financial implementing. (2) The findings of this study provided support for a systems approach to family financial management. There result indicated that it is the combined effect of inputs and throughputs that effects the output of financial satisfaction.

Among the various models proposed for the description of semi-rigid connection behavior, Kinney's fixity facto. (=f) definition is adopted. If one follows this definition, f=1.0 signifies a completely fixed connection and f=0.0, the frictionless hinge. Kim's new slope-deflection equations based on the Kinney's fixity factors are the principal idea of this paper. Proposed finite element program also includes the effect of axial shortening of column, which is neglected in the stress analysis of frame leg conventional slope-deflection method. For the economic design, especially for the saving of beam weight in the high-rise office buildings or apartment houses, the proposed method can be applied.

The 40th Annual Southern Arizona Regional Science and Engineering Fair was analyzed in terms of contents of exhibits and research methods. Elementary school students like to choose first, biology; secondly. physics; thirdly, chemistry; fourthly. consumer science; fifthly, S.T.S; sixthly. earth science area topics. Chemistry area topics are 20 %, which are much more than rates appeared in American elementary science textbooks. Elementary school students like topics such as pollutions, energy saving materials and characteristics/selection of products required in every-day life. In the most preferential area, biology, students do experiments or survey about plants growth, microbiology, learning/behavior of animals, health/exercise, which are reconcile with the analysis of American elementary science contents.

Process contract has received considerable attention in silk degumming processes because of its critical role in quality assurance. In degumming, process exhibits shrinkage of high twisted yarn and lot-varying behavior, thus increasing the difficulties of reduction by conventional means. This necessitates the application of a package that adapts to changing degumming process, and a new approach involving package degumming is proposed. The gains of this process are prevent of shrinkage by package winding, which is simplified by reduced soft-winding or re-twisting process. The approach is expected to achieve high quality results in conventional process due to its feature of demage by tension and rubbing. Therefore package degumming has many merits such as reduce of pilling and shrinkage, production expenses saving by process contract are expected of the simplified degumming process.

To achieve rapid developments and ensure competitiveness, cost saving, digital manufacturing is essential in die shops. Digital Manufacturing is a technology to facilitate effective product developments and agile productions by digital environments representing the physical and logical schema and the behavior of real manufacturing system including manufacturing resources, processes and products. For applying digital manufacturing to die shop, engineering information managements of products, manufacturing process and resources are needed. In this paper proposes and implements, PLM approach for achieving engineering collaborations in engineering activities. We suggest detail procedures, some examples and considerations of PPR managements in die shop.

The purpose of the thesis is to develop simulation program for forecasting of optical connector. So we can achieve the time and the money saving for making the optical connector. Optical performance (insertion loss) of optical connector mainly relies on 3 misalignment factors-ferrule factor due to mis-manufacture from design, auto-centering effect that is fiber behavior phenomena between hole and fiber, fiber misalignment factor. Simulation use experimental data with auto-centering effect and fiber factor and use pseudo data with ferrule through random number generation because it is developing stage. In this study we a, pp.y kernel density estimation method with experimental data in order to know whether it belong to or not specific parametric distribution family. And we simulate to forecast insertion loss of optical multifiber connector under specific design model using nonparametric bootstrap resampling data and parametric pseudo samples from uniform distribution. We obtain the tolerance specifications of misalignment factors satisfying not exceed in maximum 1.0dB and choose optimal hole diameter.

This study examined how middle-aged jobholders anticipate their living after retirement, how they plan their post-retirement financial welfare and what attitude they have towards old age. The data came from 290 middle-aged male and female people in Incheon, Suwon and Cheongju city and were analyzed to find the differences among public planned pension types, such as the National Pension System (NPS), the Government Employee Pension Corporation (GEPC), and the Korea Teachers Pension (KTP). The major results were as follows: First, the expected income level after retirement in GEPC members was the highest and the lowest in KTP members. Second, the expected living period after retirement is the main criteria used when determining the amount of money needed for old age. Third, KTP members were of the most inferior at financial planning and practice, especially self-reflection of their expending behavior, thrift and saving practice for old age.

This is an empirical research on the effect of the product placement advertisement on the consumption behavior of college students. A structured survey to 342 students in and near Seoul shows that life style of the students significantly matters to the effect. That is, beauty-oriented students are more sensitive to the PPL than other student groups (i.e., career-oriented, saving-oriented, leisure-oriented, or freedom-oriented students). On the other hand, the freedom-oriented students are not sensitive to the PPL at all. Some statistical methods including factor analysis and multiple regression analysis were employed in order to get those results.

The effects of fillers on the wet end dewatering and paper properties were investigated in order to confirm the possibility that the fillers can be used as a means for saving energy in papermaking process. The performance of GCC, PCC and talcs were evaluated. The dewatering in wire and wet press was improved by the increase of filler addition, but it was observed that the dewatering behavior was depended by the filler characteristics. PCC was superior to other fillers in the bulk, opacity, air permeability and stiffness while the lowest tensile and burst index were obtained. We found that the response on the wet end dewatering and paper properties were affected greatly by the filler characteristics including particle shape and size.

The purpose of this study is to analyze the ultimate strength and behavior of triangular and rectangular frames in steel towers. Investigations of collapse mechanism including local and global failures of partial frame are carried out through finite element analysis and small scaled experiments. Ultimate strength and deformation are investigated in case of shape variations with change of the interior and exterior frames. The efficiency of rectangular frame saving sub-brace members are verified with comparisons of the ultimate strength of triangular frames.
