Automobile manufacturing companies should provide the products and service that can satisfy consumers who usually want various kinds of automobiles. This paper studied the relations among several demographic characteristics(gender, age, occupation, income) of consumers and automobile's attributes(engine performance, engine displacement, price, maintenance expenses, color, etc.) and preferred automobile(kind, size, company, price). For the relation research we established a model and related hypotheses and used a questionnaire survey, where 350 subjects were questioned. After the analysis, many statistically significant results are obtained : consumer's gender has relations with the preference for engine performance, engine displacement, price, color, and design; age has relations with the preference for engine displacement, maintenance expenses, free checking during A/S period, etc., occupation has relations with the preference for engine performance, engine displacement, price, maintenance expenses, fuel efficiency, etc. : income has relations with the preference for engine performance, engine displacement, price, maintenance expenses, mileage, reputation of car manufacturing companies, etc.; price and fuel efficiency has relations with the preference for car manufacturing companies. These results suggest the consumer-oriented sales of automobiles and are expected to be helpful for the effective strategy development of automobile marketing.

This study provides information for the design of pediatric inpatient uniforms with functionality and aesthetic beauty through a questionnaire-survey of the conditions of providing, wearing, preferences and improvement requirements for pediatric inpatient uniforms. As a result of the survey, intravenous injections were mostly given on the back of the hand, and the method of changing uniforms after intravenous injections was (in most cases) to pass the injection bottle through a sleeve or pant leg while the needle is inserted. The respondents answered that the sleeve length and pant length did not match. As a result of the preference of the pediatric inpatient design survey, respondents indicated they preferred pajama type, yellow color and medium size animal patterns. A similar ratio of set-in and raglan with no collar but with 3/4 length sleeve of round neck, front end, sleeve top opening, button closing and two pockets were preferred for shirts; however, a 3/4 length with rubber string on the waist, no opening and inner opening were preferred at the same ratio for pants. As for the method to adjust the length to assign functionality to pediatric inpatient uniforms, the most preferred sleeve was a roll-up sleeve with a strap and the most preferred pants were length adjusted pants that used a strap for both shirts and pants with a both sides strap. In addition, the majority of the respondents answered that a hand wrapper that protects the injection location during intravenous injections needs be developed. As for the development type, a half glove type and glove type were preferred in sequential order.

The purpose of this study was to evaluate the color image of the natural-dyed silk fabrics. The dye was extracted from pine needle by boiling pine needle with ethanol at $78^{\circ}C$ for 3hours and distilled water at $100^{\circ}C$ for 2hours. The 100% silk fabric was dyed of extract in pH 5 at $90-100^{\circ}C$ for 1 hr. As mordants used were compounds of Al, Sn, Fe, and Cr, color image of pine-needle dyed silk fabrics was classified into 5 factors (pure, gentle, sophisticate, comfortable, pastorale) and the factor pure is most important one of those. Most cheerful image in pure factor was from the fabrics dyed with ethanol extract and then, none and Cr mordanting. Dignified image was from the fabrics dyed with ethanol extract and then, Cu or Fe mordanting. In production, products dyed with ethanol extracts was preferred to those dyed with distilled water extracts. Color image and preference of the silk fabrics dyed with pine needles extracted was affected by extraction solvents and mordants.

Preferred combinations of illuminance and color temperature of lighting depend on daily living activities. We investigated whether the illumination stimuli of LED lighting can enhance attention and relaxation level by controlling color temperature and illuminance level according to activities. Illuminations and color temperatures of LED flat panels are controlled in accordance with activities such as office work and resting. The attention and relaxation level under the task specific lightings are compared with those under normal lighting condition. Single channel EEG signals from the NeuroSky's Mindset are used to estimate attention and relaxation level of human subjects under different lighting conditions. Experiment results show that high color temperature with high illuminance of LED lightings (6600K, 800lx) shows improved attention level compared with conventional lighting conditions (4000K, 500lx).

소비자 선호의 만족은 제품의 성공의 중요한 열쇠이다. 그렇기 때문에 디자인 관리자들은 소비자선호에 대해 면밀한 검토를 통해 수익성 있는 제품 디자인을 개발하려고 노력한다. 이러한 선호 디자인제품과 디자인 요소간의 영향에 관련한 연구들이 꾸준히 연구되어 왔으나 기존 연구들을 살펴보면 대다수의 연구에서는 개별제품에 대한 선호되는 디자인요소만을 다루고 있어 선호되는 디자인에 있어서 제품군별 연관성 및 차별성을 파악하지 못하고 있다는 한계점이 있었다. 따라서 본 연구는 여러 제품군들 간의 디자인요소와 소비자 선호와의 관계를 살펴 공통적인 선호 디자인요소와 개별 제품군에서만 선호되는 차별적인 선호 디자인 요소를 찾아 이를 통해 디자이너나 디자인 관리자에게 성공적인 제품 개발의 가이드라인을 제공하는데 목적이 있다. 이를 위해 본 연구에서는 휴대용 전자기기 중 전자사전, 노트북, 휴대폰, MP3플레이어를 대상으로 4개 제품에 대한 공통의 선호 디자인요소와 각각 제품별 선호 디자인요소를 분석해보았다. 이를 위한 분석 방법으로, 4개의 개별 제품군에서 공통적으로 디자인요소가 선호에 미치는 영향은 계층적 회귀분석을 사용하여 분석하였고, 개별 제품군에서 디자인 요소가 제품 선호에 미치는 영향은 회귀분석을 사용하였다. 분석결과에서, 이 4가지 제품군의 공통 선호 디자인요소 분석에서는, 전체바디타입은 영향을 미치지 않고, 전체 바디 컬러가 흰색일 경우 재질은 금속재질일 경우 광택이 경우 선호했고, 개별 제품군별 선호디자인요소의 경우, 전자사전의 경우, 바디형태가 타원형일수록, 컬러가 블랙일 경우, 노트북의 경우 개별선호 디자인요소와 공통 선호 디자인요소가 같으며, 휴대폰의 경우 재질이 플라스틱일 경우, MP3 플레이어의 경우 바디형태가 직사각형이고, 재질이 플라스틱이 선호되는 것으로 나타났다. 본 연구는 다양한 제품군에 있어서 선호에 영향을 미칠 수 있는 디자인요소를 분석함으로써 제품군별 공통의 선호 디자인요소와 개별 제품별 선호 디자인요소를 파악하여 디자이너에게 제품 개발시 좀 더 명확하고 합리적인 디자인적 시사점을 제시할 수 있다는 측면에서 의의가 있다고 할 수 있다.

Analysis of design preference to Korean and Chinese casual style were made targeting Chinese female students in Korea. The following conclusion was derived from the result of final 300-copy survey data, using SPSS 18.0 program. The data were analyzed by frequency, t-test, chi-squre independence test, ANOVA and Scheffe test. Firstly, when comparing change of design preference before the stay in Korea with after the stay in Korea, the biggest change in their preference was character casual style, while the least change was easy casual wear. In terms of duration of stay in Korea, the biggest change was from the group of over 3 years, and in the order of the group of 1-3years, and then lastly less than 1 year, which suggests that the longer the duration of stay, the bigger the change. When comparing preferred clothing color before the stay in Korea with after the stay in Korea, both before and after the stay in Korea had the highest preference for achromatic colors. The frequency of change was mostly from achromatic color to other colors. In the preferred clothing pattern, 'plain' was their favorite one before the stay in Korea, while it turned to 'nature pattern' after the stay in Korea, followed by 'plain' one. In the textiles, the most preferred one was 'cotton', before and after the stay in Korea. However, their preference for cotton was lower after their stay in Korea than before the stay in Korea, and instead there was more preference for 'silk', 'synthetic fiber', and 'other' sources.
