본 연구는 Duncan-Johnson과 Donchin(1979)과 Soskins, Rosenfeld와 Niendam(2001)의 연구를 부분적으로 확장한 것으로, EEG를 측정할 때 사용하는 고역통과필터의 값이 P300의 파형에 미치는 영향을 관찰하였다. 시각자극을 이용한 세자극 오드볼 과제를 수행하는 동안 뇌파를 측정하였으며, Fz와 Pz에서 측정한 뇌파를 0.01Hz, 0.3Hz와 1.0Hz의 고역통과필터를 사용하여 여과시켰다. 0.3Hz의 고역통과필터를 사용한 경우에는 P300 진폭이 크게 감소하지 않았지만, 1.0Hz의 고역통과필터는 P300의 진폭을 크게 감소시켰다. 0.01Hz의 고역통과 필터를 사용한 경우에는 P300 이후 부적 정점이 나타나지 않았으며, 0.3Hz와 1.0Hz의 고역통과필터를 사용한 경우에는 P300 이후 부적 정점이 관찰되었다. 비목표자극과 표준자극에 대한 P300의 진폭을 변별할 때에는 0.3Hz 고역통과필터와 정점-정점 P300 측정치를 사용하는 것이 0.01Hz나 0.3Hz, 1.0Hz 고역통과필터와 기저선-정점 측정치를 사용하는 것보다 더 효율적인 경향이 있었으며, 1.0Hz의 고역통과필터를 사용한 경우에는 정점-정점 P300 측정치가 기저선-정점 P300 측정치보다 더 유용한 경향이 있었다.

The purpose of this study was to observe street fashion, to determine preferred design of jean and to analyze preferred jean styling based on types of jean pants design, toward 20s to 30s women. We observed outfits of jean styles on the street using photography method and conducted a survey to 400 females to get information of consumers. Four hundred questionnaires were analyzed using SPSS. As a result of street research, the majority of people were wearing jean pants with T-shirts, sandal/high heel shoes and totes. The results of market research showed that preferred jean styles were significantly associated with age and marital status. Preferred color of jean pants was also significantly associated with age variable. Current popular jean style was a skinny style. We evaluated results of styling with different jean pants, creating five different images. There was a significant relationship between age/marital status and styling image in different jean styles. In a bootcut style, age variable was significantly associated with different styling images. Generally, most of people responded cute/casual image styling was the best for the bootcut style. In skinny pants, there was a significant association between a residence area and a styling image. Modern/chic image styling with skinny pants was the most favored one. In cropped jean pants, marital status was significantly associated with styling image created. We realized that we can create different images through a styling.

북한의 풍력발전 가능성을 조사하기 위한 첫 단계로 북한 지역에서의 30년 동안의 27개 지점의 지상관측자료 중 풍속과 풍향 자료를 이용하여 이 지역에서의 기후학적 바람 자원을 분석하였다. 바람자원 분석을 위해 풍속의 확률 밀도함수를 Weibull 함수로 가정하여 접근하였다. 지표로부터 50 m 고도에서 연중 평균 풍속이 4.0 m/s 이상인 지역은 대체적으로 개마고원 지역과 황해도 해안 지역이었다. 이 지역들은 비교적 바람 자원이 풍부한 것으로 나타났다. 풍속이 5 m/s 이상을 유지하는 지속시간이 가장 긴 계절은 봄이었고, 짧은 계절은 여름이었다. 관측 지점 중 장진과 양덕이 지속시간이 가장 길고 평균 풍속도 가장 큰 곳이었다.

This study investigates H-shaped houses in 1930s and examines the characters and meanings of Kim, Jong-Ryang`s H-shaped houses as a new trial to urban Hanok of those days. He, who was concerned about the housing problem of Seoul, made an attempt to make various types of dwellings. Among them, this study focuses on Japanese-Korean Style H-shaped houses in Samcheong-dong. As the alternative housing type against other urban Hanok of Seoul in 1930s, the H-shaped houses of Kim, Jong-Ryang had characters as follows : 1) H-shaped house has two special characters. First, the whole space of a single house can be divided into a left region and a right region. Second, it can be divided to a front region and a rear region. In his H-shaped houses, the left/right division was expressed as folding of space-layers in parallel with urban streets. The front/rear division was used as classification of main-living space and sub-living space. 2) KJR`s H-shaped Japanese-Korean Style houses were proved to be designed as urban housing against the extreme housing shortage of Seoul in 1930s. 3) His houses however were not accepted broadly as a urban house type because the construction cost of those was higher than an average and the element of Japanese style house was not adapted to Korea. Kim, Jong-Ryang`s trial is valuable because it was the rare case of realization of many discourses as defects of existing house type. With more rigorous investigations on KJR`s experiment in modern house type, we could understand the housing condition of Seoul in 1930s and modern urban houses more than before.

The potato tuber moth (PTM, Phthorimaea operculella (Zeller)) is a serious pest of potato (Solanum tuberosum L.) plants in the field in regions with warm temperate to tropical climates, and of tubers stored under ambient temperatures post-harvest. Although PTM can be a minor to serious pest depending on the area and year, this pest is getting more and more serious to potato fields in Korea according to accidental surveys. Son (1979) represented 12.5℃ of average annual temperature as northern limit of distribution where corresponding to Youngdeog, Dalseong, Boseong and Jindo regions. Soon after, Choi and Park (1980) reported that the northern limit of PTM distribution coincided with -8℃ isotherm for average annual minimum temperature of January. In recent years, concerns on PTM occurrence and damage to potato are increasing due to climate change resulted in global warming. We carried out an extensive survey of PTM distribution using sex pheromone traps at 24 sites across the nation in 2009. As a result, we confirmed that the northern limit of PTM distribution climbed to southern Gyeonggi and middle Gangwon regions from Gyeongbuk and Chungbuk regions indicated by Choi and Park (1980). Hereafter, we are trying to investigate why drastic going northward of PTM happened in Korea. Here is one presumption that a sudden rise in average temperature has occurred during 30 years, from 6.34℃ in 1973 to 7.62℃ in 2007, especially around Daegwallyeong area where is a typical highland with 800 m high.

At the end of April, 2009, the number of mobile phone users reached about 46 million in Korea. Consequently, the mobile shopping market is growing rapidly, and fashion products are one of the most concerned categories in mobile shopping market. In the meantime, the growth rates of domestic fashion industry and fashion retail market are forecasted very slow. In this situation, however, the growth rate of on-line shopping market including internet shopping, TV home shopping, and mobile shopping is estimated more than 12% per year until 2010. Particularly, mobile shopping area is forecasted the most rapid growing field. The objective of this study were to confirm the factors which had influences on mobile fashion shopping and to examine the effects of these factors affect the attitude toward mobile fashion shopping and the using intention of mobile fashion shopping. With the results, marketing strategies for mobile fashion shopping companies would be proposed. Date were gathered from 125 respondents of 20's and 30's females and were analyzed by AMOS 7.0. The key points of the results are; 1) The 5 factors of instant access, individualization, amusement, usefulness and ease of use which extracted from preceding researches were confirmed as the characteristics of mobile fashion shopping, 2) among these factors, amusement and usefulness had positive influences on the attitude toward mobile fashion shopping, 3) reliability on mobile fashion shopping didn't had an influence on the attitude toward mobile fashion shopping significantly, but had a positive influence on the using intention of mobile fashion shopping directly, and 4) the attitude toward mobile fashion shopping affects using intention of mobile fashion shopping positively. With these results, mobile fashion shopping companies can establish marketing strategies from various angles.

Fe-Cr steels are the most promising candidate for interconnect in solid oxide fuel cells. In this study, an effective, dense and well adherent (LaSr)(CrCo) [LSCC] coating layer was produced onto 430 stainless steel (STS-430) by atmospheric plasma spraying and the oxidation behavior as well as electrical properties of the LSCC coated STS-430 were investigated. A significant oxidation of pristine STS-430 occurred at in air environment, leading to the formation of and scale layer up to after 1200h, and consequently increased an area specific resistance of . Although the plasma sprayed LSCC coating contained the characteristic pore network, the coated samples presented apparent advantages in reducing oxidation growth of STS-430, resulting a decrease in oxide scale thickness of at after 1200h. The area specific resistance of the LSCC coated STS-430 was much reduced to after exposure at for 1200h, compared to that of the pristine STS-403.
