전화면접을 개별직접면접에 대한 매력적 대안이 될 수 있지만 두 가지 자료 수집방식에서 동일한 결과를 얻을 수 있는지에 대하여는 많은 의문이 제기되어 왔다. 이러한 의문에 대답하기 위해서는 i)전화면접에 대한 피면접자의 선호도, 면접의 속도, 개방질문에 대한 응답의 상세성, 미응답 항목의 비율 등 직접효과 ii) 통계적 추정량 iii) 면접자의 차이와 자료수집양식 등의 관점에서 경험적 문헌검토를 하였다. 이러한 차이는 전화면접에 대한 사회적 소망성 효과, 서베이 질문에 대한 인지능력 및 양식효과와 면접자 효과로 설명될 수 있다.

We studied the human visual performance with PDP and LCD to clarify the relationships between viewer preference and chromatic adaption. In this paper, optical performance of the display is measured mechanically based on standard. The human visual performance about the display color image quality trough optical process is represented numerically based on CIECAM02. By comparing these results with the result of the questionnaire, performance of the display can be evaluated in detail.

추천시스템은 사용자의 과거 구매행동을 통해 향후 구매할 것이라고 예상되는 제품을 자동으로 검색하여 추천해준다. 특히 전자상거래 기업의 상품추천시스템은 일대일 마케팅의 대표적 실현수단으로 가치가 있다. 하지만, 전통적인 추천시스템, 특히 학계 및 산업계에서 가장 널리 사용되고 있는 전통적인 협업필터링 기법은 단일차원의 '종합 평점'만을 고려하여 추천결과를 생성하도록 설계되어 있어, 사용자들의 정확한 니즈를 이해하고 대응하는데 근본적인 한계가 있다. 최근에는 전자 상거래 기업들도 고객들로부터 보다 다각화된, 다기준 방식으로 피드백을 받고 있다. 특히 다기준 평점은 정량적으로 입력되는 정보이므로 상대적으로 분석 및 처리가 용이하다는 장점이 있다. 그러나 다기준 평점 역시 사전에 정해진 기준에 대해서만 사용자의 피드백이 이루어지기 때문에, 보다 상세하게 사용자의 의견을 이해하여 추천에 반영하는 데에는 한계가 있다. 이에 본 연구는 다기준 평점 정보와 선택적 협업필터링의 서로 다른 접근방법을 통해 도출된 추천결과를 종합하여, 최종적으로 추천 대상리스트를 산출할 수 있는 하이브리드 기술을 제안한다. 본 연구에서 제안한 연구모형의 유용성을 검증하기 위해, 식음료점(식당, 카페 등)에 대한 실제 이용자를 대상으로 온라인 설문을 통해 종합 평점과 다기준 평점을 수집하였으며, 데이터를 학습용과 검증용으로 구분하여 학습시키고 성과를 평가하였다. 이 기법은 결합 함수 기반 접근법과 사용자마다 구매의사결정의 체계가 다르다는 전제하에, 사용자들을 유형화하고, 유형에 따라 정보원을 선택적으로 활용하는 협업필터링 알고리즘을 활용했다. 실험결과, 제안 알고리즘을 통한 추천 방법이 단일 차원을 고려하는 전통적인 협업필터링과 비교해 더 우수한 예측정확도를 나타냄을 확인했다. 아울러, 본 연구가 제안하는 다기준 평점과 선택적 협업필터링 알고리즘을 종합하여 추천하는 방법이, 단순히 다기준 평점을 고려했을 때 보다 통계적으로 유의한 수준의 정확도의 개선이 이루어짐을 확인할 수 있었다.

This study examines the actual conditions of toddler playwear preference survey for design and function. The study develops proper indoor and outdoor playwear for toddlers based on the analysis. A survey of 200 parents with toddlers between 2 and 6 years old and 120 teachers was conducted to find the conditions and needs for playwear along with the necessary design elements. Second, 6 designs including 3 designs for indoor playwear and 3 designs for outdoor playwear were made. These designs emphasized on soil contamination part, color, pattern, form, material, detail, and fasteners. Art play and cooking play are considered for indoor playwear and ways to decrease contamination on sleeve hem, elbow, chest, and knee were determined through the use of yellow, green, and blue colors. Applying a character and separate top with sleeves were determined. Light with breathable and waterproof fabric was determined. The correct amount of Velcro fasteners or buttons was determined for front fastening in addition a pocket was considered necessary as a detail part. The common design for both boys and girls along with a proper design for diverse play were determined. For outdoor playwear, water play, sand play, movement play, and ecology experience are considered and ways to decease contamination on hip, sleeve hem, and knee should be applied to the design as determined through the use of yellow, green, blue, and red colors. The demands for pattern, form, material, and details were similar to indoor playwear. Zipper and buttons for front fastening were determined. These final 6 playwear designs are presented using CAD WALK DESIGNWARE.

이 논문에서는 개체에 대한 신뢰도를 계산하기 위해 여러 가지의 평가기준을 이용하고, 또한 다른 개체들로 부터의 추천정보를 이용하는 신뢰모델에 대해서 제안한다. 제안한 모델에서는 개체의 신뢰도를 개체가 주어진 상황에서 만족스러운 결과를 낼 기대값으로 정의한다. 다른 개체와 상호작용이 일어날 때마다 각 평가기준에 빠른 평가결과가 얻어진다고 전제하는 상황에서 적용되는 신뢰 모델이다. 제안한 모델에서는 신뢰정보가 요구될 때 우선 결과확률 분포와 개체의 평가결과에 대한 선호도를 고려하여 각 평가기준에 대한 만족정도를 계산한때, 이렇게 계산된 만족정도 값들은 각 평가기준의 중요를 반영하여 하나의 신뢰값으로 결합된다. 이때 추천 정보도 신뢰값에 함께 결합되는 모델이다.

The purpose of this study is to compare the difference between Beijing and Seoul in women's winter street fashion, and suggest strategic methods to improve new competitiveness of the Korean fashion industry. The research was conducted by literature review and empirical research and photographs of winter street style were directly taken by a digital camera from December 28, 2008 to January 8, 2009. The survey was made at 9~11 A.M., 12~1 P.M., and 3~5 P.M. during midweek and weekend. Then 530 photographs(265 each city) of women of the 20s and 30s were selected by random sampling and five fashion professional including this researcher classified styles in accord with majority opinion on careful investigation. The results of comparing the 2008 winter street fashion in Beijing and Seoul show the highest frequency of easy casual style. In detail, while high frequency was found in romantic, classic, feminine, and romantic casual style in Seoul, easy casual and character casual style was prevalent in Beijing. The same frequency of sport casual style illustrates no differences between two cities. Unlike the prediction of the fashion industry that the preference of sport casual style would be increased under the influence of the Beijing Olympics 2008, high preference of easy casual reflects that Chinese women were more sensitive to the changes of their consumption trend. In clothing color, the achromatic color was prevalent in street style in Seoul, whereas multi-color were preferred in Beijing, suggesting a great difference. In the case of accessories, both areas preferred a tot bag but Beijing women preferred active shoulder bag and cross bag in sport casual style. Seoul women preferred pumps and sneakers, whereas Beijing women liked boots of different length according to style.

The purpose of this study is to determine how the people's view on afterlife affects their perception about shrouds. As part of analytical research, the survey was carried out to take a look at the basic thoughts that average persons have on afterlife. This paper also performed the survey on what the shroud reminds the subjects of. Specifically, the questionnaire survey was conducted to see what the people think the necessity and appropriate cost of shroud and see if they have any plan to get it provided in detail. Data from this work were statistically processed and empirically analyzed. Findings of this study can be summarized as follows. As to the funeral methods, the subjects in this work preferred cremation to burial. It was found that they recognized shrouds as necessary, but they did not have a thought in a serious manner that the suit for the dead would affect the repose of the dead and guide his or her soul to the heaven. Those respondents did not have any immediate plan to purchase shrouds, either. However, they considered the price of shroud as most important when they might come to choose the garment. With regard to the quality, it turned out that they preferred the domestic shrouds whose material are natural to those from foreign country. Also, they opted for such a kind whose shape is not so different from that of casuals they would usually wear and whose color is same to the main material of the original garment. The common material preferred most by the subjects was a hemp. The subjects' view of afterlife was not greatly related not only to how much they recognized shrouds as necessary but also to their preference for materials and patterns. On top of this, their unique taste for particular types of shroud was found to be significantly dependent on whether their view of afterlife is positive or negative, whether they firmly believe in afterlife, whether they take the absolute predestination and whether they accept the prayer-effect relationship in terms of psychology.
