The purpose of this study was to examine the effects of facing plan on store image and preference of young casual fashion store. The subjects were 545 male and female university students in Chungnam province. The measuring instruments were 7 stimuli manipulated by facing plan, an important VMD element, and self-administrated questionnaire consisted of store image, store preference and subject's demographic characteristics. The data were analyzed by t-test, ANOVA and Duncan's multiple range test, using SPSS program. The results were as follows. First, facing type significantly affected consumer' store image; folded type had more neat and elegant image than other facing types, and face out type had most comfort image, whereas sleeve out type had discomfort image. Second, arrangement of facing types also affected store image; style arrangement had more sophisticated image than color arrangement in sleeve out type, and vertical and horizontal arrangement had more neat, sophisticated, attractive and comfort image than separate arrangement in folded type. Third, facing type affected store preference; folded type showed higher store preference than sleeve out type. Forth, arrangement of folded type affected store preference; vertical and horizontal arrangement showed higher store preference than separate arrangement. Fifth, store image and preference were different by subject's sex; male subjects perceived style arrangement as more elegant, characteristic and attractive image, and showed higher store preference than female subjects on separate arrangement of folded type.

The semi-solid casting will have a higher internal integrity, mechanical properties and dimensional accuracy than the conventional castings. This process can reduce the manufacturing costs and finished weight for critical components. The semi-solid casting are capable of greater dimensional repeatbility, this supplies considerable savings when extensive machining, salvage and scrap are key variables in the current automotive product. One of the most important factor regarding the semi-solid die casting process are the reheating method of the raw materials to the semi-solid state. Therefore, in this present work, the horizontal type induction heating system to obtain the optimal reheating conditions suitable for semi-solid die casting process was designed and manufactured. And the microstructure of reheated materials was investigated.

In the present paper, the hydrodynamic properties of a Rahmen type flexible porous breakwater with dual fixed pontoon system interacting with obliquely or normally incident small amplitude waves are numerically investigated. This system is composed of dual vertical porous membranes hinged at the side edges of dual fixed pontoons, and a submerged horizontal membrane that both ends are hinged at the steel frames mounted pontoons. The dual vertical membranes are extended downward and hinged at bottom steal frame fixed into seabed. The wave blocking and dissipation mechanism and its effects of permeability, Rahmen type membrane and pontoon geometry, pretensions on membranes, relative dimensionless wave number, and incident wave headings are thoroughly examined.

In this study, the idea of damping force linearly proportional to horizontal isolation displacement is implemented into sloped rolling-type bearings in order to meet different seismic performance goals. In addition to experimentally demonstrating its practical feasibility, the previously developed analytical model is further modified to be capable of accurately predicting its hysteretic behavior. The numerical predictions by using the modified analytical model present a good match of the shaking table test results. Afterward, several sloped rolling-type bearings designed with linearly variable damping force are numerically compared with a bearing designed with conventional constant damping force. The initial friction damping force adopted in the former is designed to be smaller than the constant one adopted in the latter. The numerical comparison results indicate that when the horizontal isolation displacement does not exceed the designed turning point (or practically when subjected to minor or frequent earthquakes that seldom have a great displacement demand for seismic isolation), the linearly variable damping force design can exhibit a better acceleration control performance than the constant damping force design. In addition, the former, in general, advantages the re-centering performance over the latter. However, the maximum horizontal displacement response of the linearly variable damping force design, in general, is larger than that of the constant damping force design. It is particularly true when undergoing a horizontal isolation displacement response smaller than the designed turning point and designing a smaller value of initial friction damping force.

Casing Oscillator is a construction machine that used to insert casings which is based on construction of a building or bridge into the ground. The purpose of using casing supports a pile or in case when heavy loads and moments happens. It is very important that the casings are retaining perpendicular to sea level regardless of the slope of the ground. So it requires that Casing Oscillator keep horizontality. But, it was useless a horizontal control without another heavy equipment. Tornado is a type of Casing Oscillator to advance. It controls horizontality with 4 cylinders. Those cylinders controlled by high-speed solenoid valves. This paper represents horizontal control of the Tornado using Kinematics. First. the horizontal control simulated by AMESim, which is simulation tool. then it compared with experimental results.

In horizontal cells (HCs) that were freshly dissociated from goldfish retina, two types of voltagedependent calcium currents ($I_{Ca}$) were recorded using a patch-clamping configuration: a transient type current and a sustained type current. The cell was held at -40 mV, and the prepulse step of -90 mV was applied before command pulse between -65 and +55 mV. The transient $Ca^{2+}$ current was activated by depolarization to around -50 mV from a prepulse voltage of -90 mV lasting at least 400 ms and reached a maximal value near -25 mV. On the other hand, the sustained $Ca^{2+}$ current was induced by pre-inactivation for less than 10 ms duration. Its activation started near -10 mV and peaked at +20 mV. $Co^{2+}$ (2 mM) suppressed both of these two components, but nifedipine ($20{\mu}M$), L-type $Ca^{2+}$ channel antagonist, blocked only the sustained current. Based on the activation voltage and the pharmacolog$I_{Ca}$l specificity, the sustained current appears to be similar to L-type $I_{Ca}$ and the transient type to T-type $I_{Ca}$. This study is the first to confirm that transient type $I_{Ca}$ together with the sustained one is present in HCs dissociated from goldfish retina.

Four types of horizontal joint were tested to investigate the difference with regards to the compressive behavior and strength. These include wedge-type joints (i)with and (ii)without transverse reinforcement against splitting failure of the panel concrete, and wedge-type joints (iii)with different widths of joint concrete (6cm vs 8cm) and (iv)closed platform joint. It was shown that the compressive strength of wedge-type joint is about 10% higher than that of closed-type (platform) joint. But the effect of transverse reinforcement and joint concrete widths on the strength of the joints turned out be negligible. Also, the moduli of elasticity in panel and joint are compared and the equivalent moduli of the whole wall are derived.

V type suspension string sets prevent instabilities from swing motion by the horizontal angle and by wind pressure. These installation conditions are controled mainly 3 items - normal swing angle by horizontal angle of line, unusual swing angle by strong wind, minimum vertical loads. We calculated and analysed that factors for the 765kV transmission line condition. And we were tested swing characteristics of V-string sets in real size test situation. So, we find to installation condition for the V type suspension string sets. This results will be used to design of V type suspension string set and to decision of the installation condition.

Grain yields of errect-leaved corn hybrids were reported to be increased as planting density(PD) increased compared to those of horizontal leaf type hybrids. This trial was conducted to investigate the difference between errect and horizontal-leaved hybrids in response to different PD. Grain yields of both type hybrids were decreased at the highest PD, however, that of horizontal-leaved hybrid, Ga209 ${\times}$ Ki14A, was decreased more than errect-leaved hybrids which indicated varietal difference in response to PD. Responses to PD for days to tasseling, plant height, ear height, and leaf angle were not significant, also, PD ${\times}$ hybrid interactions were not observed. Yield components were decreased as PD increased and there were no PD ${\times}$ hybrid interactions for these characters. Leaf angle was negatively correlated with grain yield and yield components except for kernel weight.

In this paper, the discharge image of NO particles wire-cylinder type electrode in the discharge reactor where AC dielectric barrier type corona discharge occurred and horizontal and vertical signal intensity at each flourescence emission during discharge and the horizontal and vertical signal strength of NO particles at flourescence emission wavelength band[236[nm], 247[nm]], were measured were measured by ICCD Camera. In addition discharge images and signal intensities in accordance with discharge time were measured to figure out the discharge mechanism. It was found that the strongest horizontal and vertical signal intensity of NO particles were observed at 247[nm] band, but no big difference in the horizontal and vertical signal intensity in accordance with discharge time was seen. In particular, the phenomenon image occuring inside the discharge reactor and wavelength ware able to be carried based on the measured data.
