Purpose - The purpose of this study is to investigate the effect of model attractiveness on brand attitude and purchase intention, and examine whether product-model match-up plays a moderating role in the relationship between model attractiveness and brand attitude and purchase intention. The model attractiveness is consist of psychological and physical attractiveness of the model. The authors investigate how product-model match-up influence the strength of the relationship between model attractiveness - brand attitude and purchase intention. The purpose of this is to test whether product-model match-up influence the form and effectiveness of a model attractiveness on brand attitude and purchase intention and suggest the effective and efficient methods in the model selection strategies to increase advertising effectiveness based on the results of this study. Research design, data, and methodology - The experimental design for this study was the between subject design based on 2 group of the psychological attractiveness(high vs. low) × product-model match-up(high vs low) and 2 group of the physical attractiveness(high vs. low) × product-model match-up(high vs low). And a preliminary investigation was conducted to develop experimental stimuli through manipulation check to enhance the external validity of experimental research. The attractiveness of the model and product-model match-up are independent variables and manipulative variables in presentation of experimental stimuli. The self-administered methode experiment was conducted on 300 subjects in four groups constructed according to the independent variables. Result - The findings provide partial support for a moderator for product-model match-up on the model attractiveness - brand attitude and purchase intention. First, the influence of psychological attractiveness and physical attractiveness on brand attitude and purchase intention was shown significant. Also, it was found that the average value of brand attitude and purchase intention according to psychological attractiveness was significantly higher than the average value of brand attitude and purchase intention according to physical attractiveness in additional analysis. Second, the average value of brand attitude and purchase intention were higher when product - model match-up was high in both high and low psychological attractiveness and physical attractiveness of the model. However, in the case of psychological attractiveness, the correlation effect with product - model match-up was significant, but in the case of physical attractiveness, it was not significant. Conclusions - The results of this study suggest that the attractiveness factor should be considered in selecting the ad model by verifying the effect of the attractiveness of the model on the advertising effect. In particular, this study has great significance both academically and practically in terms of suggesting such implications that the advertising effect of psychological attractiveness and physical attractiveness may be different depending on the product type by additional analysis.

현대인들은 의식적 혹은 무의식적으로 많은 광고에 노출되고 있다. 이에 기업에서는 매력적인 모델을 광고에 사용함으로써 자사의 광고에 소비자들의 주목도를 높이려는 것이 일반적인 경향이다. 의류의 경우, 소비자는 주로 잡지, 신문, 카탈로그, TV 광고 등의 마케터 주도적 정보원을 통해 정보를 수집하는 것으로 나타나, 마케터가 제시하는 광고가 의류 소비자의 구매행동에 영향을 미친다는 것을 알 수 있다. 따라서 본 연구에서는 의류광고에 사용되는 모델이 소비자에 의해 의류광고에 적합하다고 판단되어지는 경로를 이론적으로 도출하고 이를 실증적으로 검증하였다. 그 결과, 모델의 매력도 차원에는 '관능성'과 '귀염성', 두 차원이 존재하며, 이 차원은 각각 다른 경로로 의류광고 적합도를 향상시키는 것으로 나타났다. 관능성은 '모델답다', '전형적인 모델이다'로 여겨지는 '모델 전형성'을 통해 의류광고 적합도를 향상시키며, 귀염성은 모델 전형성을 거치지 않고 의류광고 적합도에 직접적으로 영향을 미치는 것으로 나타났다. 이러한 결과는 기업이 의류모델을 선정함에 있어 유의한 시사점을 제공한다.

In this paper, we report the development of two DEM (digital elevation model) generation algorithms over urban areas from an IKONOS stereo pair. One ("EpiMatch") is originally developed for SPOT images and modified for IKONOS images. It uses epipolar geometry for accurate DEM generation. The other is based on graph-cut algorithm in 3D voxel space. This algorithm is believed to work better on height discontinuities than EpiMatch. An IKONOS image pair over Taejon city area was used for tests. Using ground control points obtained from differential GPS, camera model was set up and stereo matching applied. As a result, two DEMs over urban areas were produced. Within a DEM from EpiMatch small houses appear as small "cloudy" patches and large apartment and industrial buildings are visually identifiable. Within the DEM from graph-cut we could achieve better height information on building boundaries. The results show that both algorithms can generate DEMs from IKONOS images although more research is required on handling height discontinuities (for "EpiMatch") and on faster computation (for "Graph-cut").

Surface Solar Insolation is important for vegetation productivity, hydrology, crop growth, etc. In this study, Surface Solar Insolation is estimated using Multi-functional Transport Satellite (MTSAT-1R) in clear and cloudy conditions. For the Cloudy sky cases, the surface solar insolation is estimated by taking into account the cloud transmittance and multiple scattering between cloud and surface. This model integrated Kawamura's model and SMAC code computes surface solar insolation with a 5km ${\times}$ 5km spatial resolution in hourly basis. The daily value is derived from the available hourly Surface Solar Insolation, independently for every pixel. To validation, this study uses ground truth data recorded from the pyranometer installed by the Korea Meteorological Agency (KMA). The validation of estimated value is performed through a match-up with ground truth. Various match-up with ground truth. Various match-up window sizes are tested with 3${\times}$3, 5${\times}$5, 7${\times}$7, 9${\times}$9, 10${\times}$10, 11${\times}$11, 13${\times}$13 pixels to define the spatial representativity of pyranometer measurement, and to consider drifting clouds from adjacent pixels across the ground station during the averaging interval of 1 hour are taken into account.

본 논문은 대학 졸업생의 숙련 불일치 문제에 대한 분석의 일환으로 임금으로 대표되는 노동시장성과에 대해 전공-직업 일치의 시각에서 접근한 것이다. 실증 분석에 있어서는 선행연구들에서 자주 제기되었던 표본선택편의 문제를 명시적으로 분석 과정에 반영하였고, 분석의 편의상 이항변수로 취급되었던 전공직업일치 변수도 설문조사가 제공한 다항선택변수로 설정하여 분석하였다. 특히 1982년, 1992년, 2002년 세 코호트에 대한 조사 결과를 활용하여 비교적 장기간에 걸친 노동시장의 구조적 변화도 고려하고자 하였다. 실증분석 결과, 전공일치 직업선택에 따른 표본선택편의와 전공직업일치의 임금효과를 확인할 수 있었다. 또 전공직업일치 정도와 비례해 임금프리미엄도 체증하고, 특히 전공계열별 분석을 통해 사회 계열, 공학 계열, 자연 계열에서 전공과 직업이 일치한 경우 상대적으로 높은 임금을 확인할 수 있었다. 그러나 전공 계열별로 선택편의의 영향에 차이가 있음도 볼 수 있었다. 또 1982년, 1992년, 2002년을 비교하면 1992년에 전공직업일치 경향은 급격히 낮아졌고 1992년과 2002년의 차이는 오히려 크지 않아 이 같은 숙련 불일치 현상이 상당히 오래 전부터 진행되어 온 현상임을 확인할 수 있었다.

A simplified modeling approach of forced vibration for occupied car seats was demonstrated by using a mathematical model presented in 'Free Vibration of Car seat and Mannequin System' nonlinear and linear equations of motions were rederived for forced vibration and the transfer function was used to calculate the frequency response function. The experimental apparatus were set up and hydraulic shaker was used to obtain the system responses. Through the tests mannequin's head had a lot of problems and the responses with a head and without a head were measured. To explore the effects of linear dampings and friction moments at the joints linear analyses were performed. New sets of linear spring and damping coefficients and torsional dampings at the joints were calculated through parameter study to match up with experimental results. Good agreement between experimental and simulation frequency response estimates were obtained both in terms of locations of resonances and system deflection shapes at resonance indicating that this is a feasible method of modeling seated occupants.

This paper addresses a numerical simulation of the flow and heat transfer in a simplified model of helically coiled tube steam generator using a general purpose computational fluid dynamic analysis computer code. The steam generator model is comprised of a cylindrical shell and helically coiled tubes. A cold feed water entered the tubes is heated up, evaporates. and finally become a superheated steam with a large amount of heat transferred continuously from the hot compressed water at higher pressure flowing counter-currently through the shell side. For the calculation of tube side two-phase flow field formed by boiling, inhomogeneous two-fluid model is used. Both the internal and external turbulent flows are simulated using the standard k-e model. The conjugate heat transfer analysis method is employed to calculate the conduction in the tube wall with finite thickness and the convections in the internal and external fluids simultaneously so as to match the fluid-wall-fluid interface conditions properly. The numerical calculations are peformed for helically coiled tubes of steam generator at an integral type pressurized water reactor under normal operation. The effects of tube-side inlet flow velocity are discussed in details. The results of present numerical simulation are considered to be physically plausible based on the data and knowledge from previous experimental and numerical studies where available.

Armed aircraft of a basic trainer class installs external stores under wing box by using pylon and performs an operation such as weapon delivery and jettison, and should be designed to withstand all kinds of loads applied to external stores. The static strength test of pylons and wing box was performed to assess the static strength of pylon and their support structures for substantiation. Based on the test, the structures were verified to fully satisfy a given design requirement. In this paper, methods of test load generation of wing box and pylon, evaluation of test result data and design result of test set-up were presented. Comparing the FEM analysis with the same test data can lead to good match and reasonable deviation between both. Finally, based on the test and the analysis, the static strength of test article was substantiated and the reliability and effectiveness of analysis math model were obtained.
