  • This study focused o investigating the variables dauther-in-law and mother-in=-law's subjective household crowding. And which is the best index among space per person, persons per room, and the number of family members was the next issue. the results of this study were as follows. 1. Variables that effected on the dauther-in-law's subjective household crowding were expectation about the number of rooms, the educational level of the dauther-in-law, duration of marriage, educational level of mother-in-law, space per person. In the case of mother-in-law, these were duration of marriage, space per person, expectation about the number of rooms, educational level of mother-in-law. 2. The best objective household crowding index was the space per person. Finally we need to look at the suv-dimension that composed of subjective household crowding of the old.

  • Business Information Systems are strategic applications to achieve companies' goals and innovation. This idea make companies invest their time and budget in the Information Systems. However, it is difficult to forecast effects of the investment in Information Systems and it causes hesitation of making decision. Thus, I researched a case so that I could forecast the effect of the information systems using AHP(analytic hierarchical process). In this study, I approached this matter with three views such as intelligence(review of prior literature), design(methodology development), and application. This study is significant in terms of practicality rather than theoretical dimension. Particularly, I suggested a way of quantifying in monetary value the quality aspects through inverting qualitative facts to quantitative facts and calculated the investment feasibility with it.

  • In a previous paper, the characteristics of ECC (earth continuity conductor) have been analysed for reducing the level of induced sheath voltage considering the dimension and position of ECC, the spacing between ECC and three phase cables, and the use of two ECC conductors at the single point boned section of underground power cable system. From these results, the study conditions for optimal installation has been selected such as installation section, conductor size and etc. In this paper, 5 cases which are set by possible installation conditions are tested based on previous research results. Finally, the optimal installation method of ECC is selected on underground power cable systems.

  • This paper presents a LTCC Balun-BPF, which is a BPF(bandpass filter) with a Balun in a single LTCC chip for the direct interface with a MIC chip having balanced inputs. The physical dimension of the designed Balun-BPE is $2.4{\times}2.0{\times}0.88m^3$ and the used dielectric constant ${\varepsilon}_r$ is 36. A Balun of three-lines structure with striplines and a BPF of comb-line structure was combined into the Balun-BPF. The simulated result shows 4.8dB of insertion loss, $178{\sim}179$ degree of the phase imbalance, 14dB of the return

  • The aim of this paper was to investigate images of neighborhood parks and pergola facilities. 280 individuals responded to the 19 semantic differential pollar terms for all four parks. A 7-point semantic differential scale was used. Results from the data analysis suggest several important findings; 1. Mean scores were significantly different in most of S.D.scales according to park and pergola facilities types. As compared with park, S.D.scales values of pergola varied with its visual identity in the spatial composition of park. 2. Data from the factor analysis revealed that four dimensions appeared for all park and pergola types : "Evaluation ", "Potentiality", "Variety", and "Familiarity". 3. In terms of the "Familiarity" dimension, Omok park and its pergola were viewed a ssignificantly more familiar than any of the other three areas. 4. Parks were perceived more positive than pergolas images in the dimensions of "Evaluation ", "Variety", and "Familiarity". 5. Regression analysis showed that "Evaluation "and "Variety" dimensions were mainly related to visual preference.

  • The characteristics of eddy current sensor has been analyzed by using numerical analysis which is performed by modeling eddy current sensor and analytic object into three-dimension axis-symmetry in this paper. The eddy current sensor is modeled as cylindrical shape with variation of inside and outside diameter and frequency range between 1[kHz] and 1[MHa] for numerical analysis. The value of impendence on eddy current sensor depending on frequency variation was calculated through numerical analysis. The characteristics of eddy current sensor can be studied by normalized impendence which is gained from the calculated impendence. Therefore, sensitivity of eddy current sensor depending on frequency, inside and outside diameter can be known by investigating diameter of half circle impendence and its locus.

  • The objects of the nature have three dimensional (3-D) parameters. The 3-D profiles are embedded on the photographs and microscopic images. To understand 3-D configuration, stereo pair image with thick section is frequently employed. The perception of 3-D images is possible with the aid of stereoscopic glasses, although the expert can perceive 3-D images without the glasses. Anaglyphic stereo images are constructed by various softwares from commercial and freeware. Here we would like to present an easy anaglyphs construction method with Adobe $Photoshop^{(R)}$ based on tilting paired images from high voltage electron microscope. The anaglyphic stereo images constructed revealed the same 3-D perception with conventional stereoscopy. We could zoom in/out the anaglyph image digitally to investigate the detail configuration by real time. This method is expected to contribute to understanding complex structures 3 dimensionally.

  • The purpose of the study is to understand the newer and more direct design techniques, and to provide information to exert creativity in designing. The headdress, one of dress items, was selected so that the change might be investigated in designs and production methods. A headdress was manufactured on the basis of literature review and portrait analysis. The target period of the study was limited to Henry Ⅶ and Henry Ⅷl(1485∼l547) when gable headdress was put on. The details and the patterns of gable headdress were identified for the selected gable hood to be manufactured. It was not possible to get the same dress material, so a similar one was made as in the pictures. The same was done to the color. Putting the focus of the study on the reproduction of the figure in the portrait, some dimension were measured in bodily proportion and patterns were made by three-dimensional cutting. As results, some dimensions used in the manufacture had some limits.

  • A three dimension(3D) link analysis is peformed considering multipath effects caused by a reflected signal and the difference angle between the antenna bore-sight and Line-Of-Sight(LOS). In addition, a direction of a receive antenna is determined for a receiver to get maximum signal strength in a telemetry situation. For a fixed receive antenna, the angle is determined to maximize the average Carrier to Noise Ratio(CNR) over the interested part of a trajectory. For a tracking antenna, the angle at every position is selected to give maximum CNR or to direct the boresight to the flying projectile.
