  • The mutual inductances between power line and communication line above ground are studied in this paper. A long power line is discussed and the terminal effect above ground is taken into account. By applying Carson's method, the analytical solution to mutual inductances is derived and numerically evaluated. The analytical solutions derived in this paper are valid for both oblique and parallel proximity between power and communication lines, and the numerical results are compared with previous published results.

  • This study was conducted to reproduce the four-piece bodice pattern of a ladies' costume of the 1890's for Korean women in their twenties with a standard body type and average size. Eighteen four-piece bodice patterns of the ladies' costume of the 1890's were collected and drawn to actual size. The front width of the bodice was wider than the back width. The front bust line of the bodice was wider than the sum of the back bust line, the side back bust line and the under-arm gore bust line. The front waist line of the bodice was wider than the sum of the back waist line, the side back waist line and the under-arm gore waist line. The angles of the two waist darts of the bodice were very big but the legs of the dart were too short. The center front line of the bodice was oblique and curved. The angle of the back shoulder line of the bodice was bigger than the angle of front shoulder line. The shoulder seam line of the bodice was not placed on the top of the shoulder but behind the shoulder. The pattern characteristics of the bodice created a woman's silhouette that emphasized the volume of the bust, a chicken breast and a slim waist. The study pattern which had the characteristics of the four-piece bodice of the 1890's was designed like for Korean women in their twenties who have a standard body type and an average size through modifications based on the evaluation of two dressing occasions. The study pattern was evaluated to have the silhouette of the 1890's and to fit Korean women.

  • In the present study, oblique L-shaped monopole slot antenna with broadband characteristic is newly proposed. For bandwidth enhancement as well as size reduction, L-shaped slot with two open-terminations on the ground edge is used. The lower part of L-shaped slot comprises oblique form for bandwidth enhancement in low frequency band, whereas its higher part comprise tapered form for its enhancement in high frequency band. The short-circuit terminated microstrip line which is generally known to be more useful for bandwidth enhancement than open-circuit termination is used. The measured impedance bandwidth($S_{11}{\leq}-10dB$) and gain of the fabricated antenna have been observed to be 4.72 GHz (2.28~7 GHz) and more than 3dBi over the passband respectively.

  • QUICKER scheme has several attractive properties. However, under highly convective conditions, it produces overshoots and possibly some oscillations on each side of steps in the dependent variable when the flow is convected at an angle oblique to the grid line. Fortunately, it is possible to modify the QUICKER scheme using non-linear and linear functional relationship. Details of the development of polynomial upwinding scheme are given in this paper, where it is seen that this non-linear scheme has also third order accuracy. This polynomial upwinding scheme is used as the basis for the SHARPER and SMARTER schemes. Another revised scheme was developed by partial modification of QUICKER scheme using CDS and UPWIND schemes(QUICKUP). These revised schemes are tested at the well known bench mark flows, Two-Dimensional Pure Convection Flows in Oblique-Step, Lid Driven Cavity Flows and Buoyancy Driven Cavity Flows. For pure convection oblique step flow test problem, QUICKUP, SMARTER and SHARPER schemes remain absolutely monotonic without overshoot and oscillation. QUICKUP scheme is more accurate than any other scheme in their relative accuracy. In high Reynolds number Lid Driven Cavity Flow, SMARTER and SHARPER schemes retain lower computational cost than QUICKER and QUICKUP schemes, but computed velocity values in the revised schemes produced less predicted values than QUICKER scheme which is strongly effected by overshoot and undershoot values. Also, in Buoyancy Driven Cavity Flow, SMARTER, SHARPER and QUICKUP schemes give acceptable results.

  • Background Hypothenar free flaps (HTFFs) have been widely used for reconstructing palmar defects. Although previous anatomical and clinical studies of HTFF have been conducted, this technique still has some limitations. In this study, we describe some tips for large flap design that allows for easy harvesting of HTFFs with minimal donor site morbidity. Methods A total of 14 HTFF for hand defect reconstruction were recorded. The oblique flap was designed in the proximal HT area following relaxed skin tension line along the axis between fourth web space and 10 mm ulnar side of pisiform. A flap pedicle includes one or two perforators with ulnar digital artery and HT branch of basilic vein. In addition, innervated HTFF can be harvested with a branch of ulnar digital nerve. Electronic medical records were reviewed to obtain data on patients' information, operative details, and follow-up period. In addition, surgical outcome score was obtained from the patient, up to 10 points, at the last follow-up. Results Mean harvest time was 46 minutes, and two perforators were included in 10 cases. The mean flap area was 10.84 cm2. There were no problems such as donor site depression, scar contracture, keloids, wound dehiscence, numbness or neuroma pain at donor sites, and hypersensitivity or cold intolerance at flap site, either functionally or aesthetically. Conclusion Palmar defect reconstruction is challenging for hand surgeons. However, large HTFF can be harvested without complications using the oblique axis HTFF technique. We believe our surgical tips increase utility of HTFF for palmar defect reconstruction.

  • The purpose of this study was to investigate the normal range of condylar movement of normal adults. The author has observed roentgenographic images of four serial positions of condylar head taken by modified transcranail lateral oblique projection. The serial positions are centric occlusion, rest position, 1 inch open position and maximal open position. The results were obtained as follow; 1. Inter-incisal distance was 46.85㎜ in maximal open position. 2. The length between the deepest point of glenoid fossa and summit of condylar head in rest position was wider than that in centric occlusion by 0.8㎜. 3. In 1 inch open position, condylar head moved forward from the standard line in 12.64㎜ of horizontal direction and moved downwards from the standard line in 1.84㎜ of vertical direction. 4. In maximal open position, condylar head moved forward from the standard line in 19.06㎜ of horizontal direction and moved downwards from thestanard line in 0.4㎜ of vertical direction. 5. In centric occlusion, the width between glenoid fossa and margin of condylar head was greater in the posterior portion than in the anterior portion by 0.4㎜. 6. Except for the estimated figures of 1 inch open position, all of the estimated figures was greater in male than in female.

  • In this paper, we studied the configuration and depth measurement method of the crack in the interior of solid with scanning laser acoustic microscope. Precision measurement method of crack depth is required in SLAM because that system reconstructs the shadow image to the transmission coefficient. We proposed this method that used geometrical structure to the shadow area of SLAM images obtained from oblique incidence and the mode conversion of ultrasound in specimen and then experimented it. For this experiment, we fabricated various specimens which had the vertical line-crack with different depth and made the wedge as 20$^{\circ}$ for oblique incidence. Experimental results showed that the shadow area of SLAM images were proportional to the depth of crack. Measured depth error to the crack was less than 6% compared with practical crack depth.

  • A single serranid specimen of Epinephelus radiatus was collected by a hook for the commercial longline fisheries occurred near Marado, Jeju Island, Korea. The present specimen was characterized by five irregular dark brown bands passing downward and forward from upper edge of body, scales in longitudinal row 107, and pored lateral line scales 55. This species is easily distinguishable from the morphologically similar Korean serranid species of E. poecilonotus based on band patterns on body. That is, the former has five irregular oblique dark-edged brown bands, and the latter has several long horizontal bands on lateral body. We propose a new Korean name, "Ma-ra-bari," for Epinephelus radiatus.

  • As regards of designing, I chose a simple wall design of repeating pattern of vertical windows, rather than making the building as a glamourous obzet. This kind of approach was intended to pursue strong image of construction company, interchanging and communicating with its confused surrounding. Therefore, I boldly removed parts that I considered needless from the facade, and used simple and easy words clearly implying the organization. Lobby is the face of the building, but since the space is deep and narrow and the reality of lease should be considered, there was limit to give original image to the lobby. Instead, high ceiling is the biggest feature of this space. Doorae Engineering-Construction Corp. is young and energetic company. I wanted to highlight the young and energetic image of the company by crossing tore oblique piece of boards. This doesn't just has a simple function as ceiling, but also work as a major subject in the space. In addition of this powerful space of oblique lines, indirect lighting is used to emphasize the character of territory, continuity and deepness of the space. Character of territory that divides main and supplementary function and main and supplementary moving line is expressed by flow of dimension, and continuity and deepness of space is emphasized by indirect lighting flowing linearly through the crack between the ceiling and the wall.
