본 연구는 밀원식물인 아까시나무의 적지적수 조림을 위해 임지생산력을 나타내는 지위지수를 도출하고, 지위지수에 어떠한 입지환경인자가 영향을 미치는 지를 수량화이론 I방법으로 구명하고자 수행되었다. 분석에 사용된 자료는 6차 국가산림자원조사와 1/5,000 산림입지토양도 상의 임령, 우세목 수고 및 각종 입지환경인자였다. 6차 국가산림자원조사에 의한 우리나라 아까시나무 임분의 지위지수는 평균 14였으며, 범위는 8에서 18 사이에 있는 것으로 분석되었다. 그리고 지위지수에 영향하는 입지환경인자는 모암, 기후대, 토양성질, 국소지형과 해발고였으며, 수량화이론 I방법을 적용한 추정모델의 적합도는 33%였다. 이 추정모델의 적합도는 낮으나 1% 수준에서 유의성이 인정되어 지위지수와 입지환경인자 간의 상호 연관성을 설명할 수 있었다. 지위지수와 입지환경인자 간의 수량화 분석 결과, 모암은 변성암, 화성암이, 기후대는 온대중부지역 이상에서, 토성은 식양토, 미사질양토가, 국소지형은 산복 지역에서 높은 점수를 갖는 것으로 나타났다. 임지생산력(지위지수)에 영향하는 입지환경인자 각각의 편상관을 분석한 결과, 산림 내 토양의 성질과 해당 입지의 해발고에 대한 편상관계수가 0.4129, 0.4023으로 각각 나타나, 이들이 가장 영향력이 높은 인자임을 알 수 있었다.

More than 1 billion mobile apps (smartphone applications) have been released worldwide. Competition among developers of apps that are available in app stores has intensified because of increasing demand. App icons with an appealing design can instantly increase attention. Miryoku Engineering methods were used and combined with the Kansei interface model to examine the relationship between attractive icons and users. The evaluation grid method (EGM) is a qualitative method that was used to evaluate the icons, and Quantification Theory Type I is a quantitative method that was used to analyze the influence of design elements in icons. Eight attractive factors of app icons were determined using EGM, and six specific factors were identified using questionnaires. The quantitative results indicated that user cognition and emotion were influenced by the various design elements. The impact on the attractive factors of a single design element differed among users with diverse backgrounds. App icons were assessed on the basis of aesthetics to identify attractive factors and thereby assist designers in understanding and implementing design elements and improving the overall visual appeal of their apps. The result of this investigation is crucial to the presentation of app icons in online app stores.

This study aims to suggest basic materials to develop an emotional font for future Hangeul font development plan by investigating emotional reaction displayed through the subjects and by quantifying its contribution of the stimulation elements causing such reaction. For this, a survey of 150 university students who are currently enrolled in the College of Design was conducted in order to analyze correlation between 30 emotional words extracted from the Hangeul font and the selected 36 sample fonts. The combined data was described with the two dimensional dispersion using the quantification theory type III. The analysis found out that the Hangeul font forms the x-axis showing "soft(dynamic).hard(static)" and the y-axis showing "modern(light).classic(heavy)”. Specifically, there exist emotional groups such as "archaic","masculine","feminine","negative", and "modern static"on each axis. In addition, to extract the casual relationship between the value of emotional reaction and its stimulation elements quantitatively, the author indicated the emotional words of each axis and the total value of equivalent five emotional word groups as the standard variance and the constituent of Hangeul font as the independent variable, and then the quantification theory type I was used to analyze the physical elements of the Hangeul font. As a result, "the centerline of gravity(base line)" and "thickness variance of a stroke" on the two axes, and "the centerline of gravity(base line)" and "decoration" among the five groups were identified as the most influential elements that affect the emotional reaction of the subjects.

Kansei design knowledge acquisition stage is a crucial stage in kansei designing process and kansei engineering (KE) methodology. In kansei engineering methodology, it is essential to extract design knowledge or rules on relationships between customer's kansei and product design element. We attempt to construct a more powerful melted for extracting the design rules from kansei expremental data. We constucted a kansei experiment concerning color kansei evaluation, and analyzed the sane data by both conventional quantification theory type I and rough set theory. Finally, we compared the effectiveness of both methods for extracting rules and examined the extensions of rough set theory in kansei engineering.

Evaluation model for damage consciousness was established through the survey of 2,210 residents' consciousness on aircraft noise near Taegu Airport. There were none who replied that the level of the aircraft noise was as los as it was quiet. 77(3.5%) people replied the noise was normal, and 2,133(95.5%) people said it was noisy. As to the period of time when the aircraft noise occurred, 51%, 97%, 86%, 0.6% of the residents pointed out the morning time, the day time, the evening time, and the night time, respectively. Because of aircraft noise, 73%, 88%, 70%, 77%, 78%, and 33% of the residents felt it disturbing indoor conversation, telephoning, watching TV or listening to the ratio, reading or meditating, working, sleeping, and studying, respectively. It was examined that the bad effects of aircraft noise on the health were severe : 43% of the resident said they experienced embarrassment. 52% astonishment, 66% absence of mind, 61% heart-beating. 77% headaches, 78% earache, and 93% displeasure. For the survey of the residents' damage consciousness about aircraft noise, the level of aircraft noise was set as an objective variable, and gender, age, occupation. Education, the type of house, the structure of windows, the consciousness of settlement in the district, and the period of residence were set as explanatory variables. And the quantification theory I was applied to the analysis. The most influencing factor of the damage consciousness on aircraft noise was the education, the second occupation, the third age, the forth the consciousness of settlement, the fifth the period of residence, the sixth gender, the seventh the type of house, and the least influencing factor among them was the structure of windows. These findings will be a useful guideline when the government seeks to set up policies which will help solve the resident's noise problems near Taegu Airport.

The purpose of this study was to draw application elements of housing interior design according to user-oriented sensibility types. The sensibility evaluation experiments were conducted to target the general user 118 people using the sensibility evaluation tool for housing interior space. The results of the analysis were as: To produce the 'cozy' space, the colors and materials giving soft and natural feeling should be used. For the 'practical' space, type of ceiling and window that give the visually open feeling, the user-oriented furniture arrangement that allows using the space efficiently. For the 'cheerful' space, the simple and natural effects should be produced by using closed space that stable. For the 'traditional' space, the natural fishing material having rough texture should be used. For the 'unique' space, the space contained the dynamic feeling by the diagonal or vertical line and the graphic expression in the wall. For the 'congenial' emotional space, basic is the symmetric, stable and simple space. On the other hand, for the material, small size, natural texture or typical and soft materials should be used. For the 'sensuous' space, the dynamic and vertical sense of space should be expressed by the type of ceiling. The most important elements for the space of 'gorgeous' sensibility, is the color.

본 연구는 전국 난대상록활엽수종의 조림지에 대한 생육환경 및 입지환경 특성과 활착률간의 관계특성으로부터 조림적지 의사결정 기초자료를 제공하고자 하였다. 1997년부터 후박나무(Machilus thunbergii), 구실잣밤나무(Castanopsis sieboldii) 등 난대상록활엽수 10종의 신규 조림지 180ha의 148개 조사구에 대한 활착률을 모니터링 한 결과 평균 활착률은 67.0±26.9%이었다. 활착률 편차가 크게 나타난 원인은 조림 적지에 관한 실증적 현지 검증이 부족한 상황에서 다양한 입지를 대상으로 시험 조림이 이루어진 결과로 판단된다. 각 조사구별 11개 생육환경 및 입지환경 특성, 조림전후 강수 등의 정성적 설명요인과 활착률의 정량적 요인 간의 관계특성으로부터 수량화 이론 I에 따른 활착률에 대한 기여도를 분석한 결과, 조림지 상층임분 울폐도, 풍노출도, 조림 전 누적 강수량, 경사도 등의 순으로 높게 나타났다.

In Japan, deodorizing airflesheners are very popular to make air flesh by deodorizing odor in rooms, toilet as well as inside a car. There are in different features in deodorizing material of Gel and Liquid, in a shape of bottle from tall to low height, in bottle color and so on. These different features will influence the customer's feeling to the products of deodorizing airfleshener. This paper deals with the psychological evaluation of the features of deodorizing airfleshener on the SD scale with kansei words. The evaluated data were analyzed by Quantification Theory Type I that leads to the relational rules between the product feature and the kansei words. The beautiful and graceful kansei consists of low height, middle width deformed round shape, but easy operational feature is based on tall shape design. These results are helpful to develop a new product of deodorizing airfleshener.
