The aim of the present study is to compare the vowel formants between generations in Daegu dialect. 20 Daegu dialect speakers were participated in this study; 10 were in their 40's, the other 10were in their 20's. As a result, the distance of /ㅣ/ and /ㅐ/, and, /ㅡ/ and /ㅓ/ in 20's is further than 40's, while the distance of /ㅗ/ and in 20's is closer than 40's. It seems reasonable to conclude that vowels in Daegu dialect change to have their own stable space, but /ㅗ/ and /ㅜ/ does not.

본 연구는 한국이 투자대상국인 OECD국가를 대상으로 외국인직접투자에 영향을 주는 요인을 파악하기 위하여 현지국과 투자국의 문화 거리와 부패인식지수의 차이를 활용하여 외국인직접투자에 영향을 주는 요인을 규명하였다. 연구결과 문화적 차원과 부패인식지수에 따라 외국인직접투자에 차이가 나타나는 것을 살펴볼 수 있었다. 문화적 성향에 따라 외국인직접투자가 증대될 수도 감소될 수도 있으며, 부패인식지수가 높을수록 투자가 활발하게 이루어졌다. 외국인직접투자에 영향을 주는 요인에 있어서 현지국과 투자국사이의 권력거리가 작을수록, 개인주의 대 집단주의 거리가 클수록 투자건수와 규모가 증대되는 것으로 나타났으며, 투자국의 부패인식지수가 높을 때 외국인직접투자가 증대되는 것으로 나타났다. 본 연구결과를 통하여 문화와 부패인식정도가 무역거래에 영향을 줄 수 있음을 확인함으로써 무역거래시 교역당사자간의 문화적 성향과 문화적 거리를 고려하여야 하며, 공공부패 등을 비롯한 사회적 변수를 적절하게 관리함으로써 무역 및 경제성장에 영향을 줄 수 있다는 시사점을 제시하였다.

The ventilation efficiency of clothing was investigated by a trace gas method using a manikin wearing an impermeable overall under an isothermal condition, where the ventilation occurred only through the openings by diffusion. The ventilation patterns were different for each part of the body. The ventilation efficiency in the clothing microenvironment of the arm and the leg greatly depended on the distance from each opening when the wrist- or the ankle-opening was opened. When both side of wrist- or ankle-openings were opened to provide the opening area double respectively, the ventilation efficiency did not correspondingly increase twice, as compared one side opened. Even though it as certainly affected by the opening area, the ventilation efficiency was more significantly influenced by the position of openings.

This study was intended to identify the desired image and fabric preference of woman college student for apparel and the relationship between these variables. Data were collected by questionnaire distributed to 260 woman college students through August to September of 2000. After eliminating incomplete questionnaires, 236 were analyzed. The most desired image was neat, and the most preferred fabric was natural fiber textile in fiber contents and light and soft in fabric sensation. The avoided image was masculine, and the negative sensation was heaviness. As a result of factor analysis, 7 factors -cute, intellectual, animate, neat, mature, sporty, sexy- were determined in image. And 8 factors -soft, durable, flat, rigid, light, bulky, heavy, pliable- were determined in fabric sensation. These factors explained large percentage of variance respectively. Multidimensional scaling was employed to analyze the relationship between desired image and fabric preference. Two dimensions were accepted to interpret the relationship. One of the results showed the closeness among the natural fiber textile, lightness, durability and natural image. And the short distance among the blended textile, elasticity, warmness and sporty image was presented.

The purpose of this study is to analyze hydraulic characteristics of surface irrigation in a paddy field of direct seeding culture. Field experiment was performed in the paddy field of ridge direct dry seeding. Simulation by a numerical model was also accomplished with the data obtained from the field experiment. The model was developed by one dimensional zero-inertia equation and finite difference method. From the result of the field observation, the furrows of the experimental field were found to have various geometric characteristics. Advance distance and time were measured both in the field and by the model simulation for various furrow lengths and irrigation discharges. Roughness coefficients of each furrow were also estimated by the model.

In this paper, we present the study on the proposed design of a real-time transmission of a video from the drone to broadcasting station (OBVan) by using F8L10D-N LoRa Module. Nowadays, LoRa technology is proved to be the mass of low cost, long range machine-to-machine connectivity. Particularly in the field of broadcasting and communication system, F8L10D-N LoRa RF Module spread spectrum technology with long transmission distance and strong penetrative ability that is double stronger than traditional FSK as well as PSK modulation scheme.

Clothing ventilation was investigated using a manikin wearing an impermeable overall under an isothermal condition, in which the ventilation occurred only through the openings. The ventilation volume was estimated by both microenvironment volume and ventilation rate, where, the microenvironment volume was measured by an air subsitution method and the ventilation rate by a trace gas method. Microenvironment volume of the experimental garment was about 21.0 liters. Even though it was certainly affected by the distance from the opening, the ventilation rate was more significantly influenced by the opening area and the shape of air layer in the clothing. The volume of air exchange in the clothing microenvironment was affected greatly by the microenvironment volume and the opening area, and it was different for each part of the body with bigger air exchange volume in the microenvironment of the leg as compared to that of the arm.

This paper is concerned with the development of the silk trade and in particular with silk-ikat production. Early origins are explained and issues relating to the development of long-distance trade are discussed. The principal trading participants are identified and the focus is turned to silk-ikat production in Central Asia. It is recognised that the vast bulk of trade, along what became known as the 'Silk Route' (or 'Silk Road'), did not involve straight-forward or direct exchange between powers to the far east of the route and powers to the far west, but rather was done in stages between adjacent or not too distant locations. Diffusion of ideas was not therefore immediate and operational at one eastern or western extreme of a trading network but, rather, was a gradual process influencing adjacent participants, at stages between the geographic extremes over a long period of time.

An image hash, a discriminative and robust summary of an image, should be robust against quality-preserving signal processing steps, while being pairwise independent for perceptually different inputs. In order to improve the hash matching performance, this paper proposes a probabilistic dissimilarity matching. Instead of extracting the binary hash from the query image, we compute the probability that the intermediate hash vector of the query image belongs to each quantization bin, which is referred to as soft quantization binning. The probability is used as a weight in comparing the binary hash of the query with that stored in a database. A performance evaluation over sets of image distortions shows that the proposed probabilistic matching method effectively improves the hash matching performance as compared with the conventional Hamming distance.
