Currently, urban mobility is rather two-dimensional: Connections between transportation solutions like elevators, escalators, moving walks, and metro stations are static. In the future, urban mobility will require a holistic view: Seamless transportation, enabled by innovative IoT technology, is a necessity. A dialogue between the city, its buildings and transportation systems, considering the specific needs and preferences of each and every citizen, must be adopted. Travelling through the city will become a lot more individualized, interactive and customized to specific requirements.

The purpose of this study was to identity the relationship of clothing involvement, consumer characteristics, and clothing buying behavior of college female students in China. A questionnaire was developed to measure clothing involvement, materialism, conspicuous consumption, reference group influence, clothing purchasing modes, fashion information sources. The questionnaire was administered to 390 college female students in Dandong of china. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were as follows: 1. Subjects were divided into low clothing involved and high clothing involved groups according to the level of clothing involvement. 2. Three dimensions of materialism were derived by factor analysis such as Happiness-pursuing, Life-centered, and Sucess-symbolic. And three dimensions of conspicuous consumption and reference group influence were derived by factor analysis such as luxury oriented, Status symbolic, Brand-name oriented, and Comparative, Informational, Normative exactly. Clothing purchasing motives and fashion information sources were factor analysed as Social and Individual mole, and Printed & Electric-wave media, Marketer managed, Personal exactly. 3. There were significant differences between high involved and low involved consumers in consumer characteristics and clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about materialism especially in Happiness-pursuing about conspicuous consumption in status symbolic and about influence of reference group in comparative. The high involved consumers put more importance than low involved consumer individual motive as clothing purchasing motive, and marketer managed in clothing fashion information. The high invoked consumers showed more importance than low invoked consumers about evaluating attributes of product, and about store patronage criterion.

Tidal channel development is influenced by sediment type, grain size, composition and tidal current. Tidal channels are usually characterized by channel development, density and shape. Quantitative analysis of tidal channels using remotely sensed data have rarely been studied. The objective of this study is to quantify tidal channels in terms of fractal dimension and compare different inter-tidal channel patterns. For the fractal analysis, we used Box counting method which had been successfully applied to streams, coastlines and others linear features. For a study, the southern part of Ganghwado tidal flats was selected where is famous for high dynamics of tidal currents and vast tidal flats. This area has different widths and lengths of tidal channels. IKONOS and Komsat-2 MSC images were used for extracting tidal channels, and the Box counting method was applied to obtain fractal dimensions (D) for each tidal channel. Yeochari area possesses channels with linear pattern and less dense development and accordingly show low D values ranging from 1.037 to 1.038. On other hands, area (near Donggumdo and Yeongjongdo ) of dendrites channel pattern and dense development resulted in high D values from 1.2057 to 1.2667. Also, area possesses channels with linear pattern had low density about $18{\sim}24%$. Area of dendritic channel pattern had high density about $34{\sim}69%$. The difference of fractal dimensions about 0.2 according to channel development in tidal flats is relatively large enough to use as an index for tidal channel classification. Also, area where channels showed linear pattern had low density about $18{\sim}24%$. Area of dendritic channel pattern had high density about $34{\sim}69%$. Using fractal dimension and density, it would be possible to quantify the tidal channel development in association with surface characteristics.

The study examined evaluated the sanitation management state of the high school foodservice operations, as measured by temperature, humidity and airborne bacteria concentration in functional areas and further identified their relationships. Data were collected from 26 high school foodservices in Gyeonggi Province. Statistical analyses were conducted with the SPSS program using descriptive analysis and spearman's correlation. The sanitation management performances in high school foodservice scored 86.85 out of 100 points and showed higher scores in the dimensions of preparation and storing management (17.85/20 points), operation management (17.78/20 points), and cooking utensil management (17.62/20 points), while the dimensions of cross contamination management as well as personal hygiene management needed action plans for prompt improvement. The airborne bacteria concentration was highest in the dining area (179.2 CFU/plate), and requiring action plans for improvement. The relative humidity in functional areas ranged from 66.5% in the receiving area to 74.4% (dish-washing area) and the temperature of the preparation area showed an average of $25.1^{\circ}C$ with the highest of $35.4^{\circ}C$ in the dish-washing area. In terms of the relationships among airborne bacteria, temperature, and humidity, the concentration of airborne bacteria was negatively correlated with and temperature in the dish-washing area (r= -0.693, P<0.05), and no other significances were shown in the other areas.

The main purpose of this research is to examine what are the factors that affect consumer attitude by the types of clothing window display, and find if there is any difference by gender of consumer group. Total 357 data from random sample of 347 adults(156 male and 191 female) who were between 19 to 49 years of age were analyzed. Sources for the sample were companies and apartment complexes and several colleges in Seoul and Chonan to diversify by such demographics as age and social status. Factors were measured by respondents' rating of 9 statements using a 5-point Likert-type scale. SPSS(Statistical Package for Social Science) Version 10.0, is used for factor analysis in order to comprehend the factors of consumer attitude and Cronbauch's ${\alpha}$ in order to measure the credibility of questions in each factor. The main findings are as follows: First, three dimensions of consumer attitude to two types of window-display of product centered display and image centered display were identified as interest, information, and impression and theses are same to both male and female consumer group. Second, for both male and female consumer group, three dimensions of consumer attitude toward two types of window-display were same, however, included sub categories in each dimension showed a little difference. In product centered display, both male and female consumer group showed high interest in the sub categories of 'fashion' and 'informations related to the product' and they were considered same factor. Otherwise, In image centered display, two sub categories of 'having some interests in the display' and 'recognize the display that projects the image or impression of clothing well' were showed high relationship each other and they were also considered same factor. Third, Cronbauch's ${\alpha}$ of three dimensions of consumer attitude demonstrated high credibility from 0.75 to 0.91. Mean score of subcategories of attitudes toward the type of display by the gender of consumer showed high scores of 'interest' and 'impression' categories in image centered display and showed high scores of 'information' category in product centered display for both gender.

The purpose of this study is to find out the level of digital stress that people experience and to investigate the effects of socio-economic variables on that. To collect data, structured questionnaire was developed and 1,200 questionnaires were distributed through internet. There were 2 dimensions in this study to examine digital stress. First dimension was about the devices themselves: computers and the other digital goods. Second dimension was about the time digital stress occurring in consumers' decision-making process: purchasing and using. Based on Yeo&Kim(2004), sub-dimensions of purchasing and using aspects were chosen. 5 sub-dimensions in purchasing side were new technology, cost, variety of alternatives, warranty service, and informational problem 6 sub-dimensions in using field were mal(or impaired)-functioning. physical aspects, immaturity in use, pressure to use, addiction to use, and informational problem. As independent variables, sex, age, educational level, digitalization acceptability and computer usability were used. The overall level of digital stress was around the average point which was not as high as expected. Digital stress of purchasing was higher than that of using. First, in purchasing aspects, the level of digital stress was relatively high in cost, variety of alternatives and warranty service. Hence, clear communications with consumers about the distinctive aspects and cost of digital devices in market are needed. Secondly, in using side, mal-functioning and physical aspects were relatively more powerful stressors. In the other words, the more serious problems were not from the characteristics of individual consumers but from those of products. Producers should put their best efforts to reduce imperfection (defectiveness) and develop user-friendly digital devices. Also, users' individual efforts to overcome the problems that can be solved privately are necessary. Finally, it was discovered that sex and computer usability were very important variables on digital stress. To extend computer usability of consumers and get over digital illiteracy, it is essential to expand the paths to give chances for people to contact with computers and other digital goods. Still there are lots of people whore computer-illiterate or low-skilled at computers. In policies or educational programs made by government, communities, or schools, more attention should be paid to the digitally vulnerable groups.

데이터베이스 질의 최적화기는 가장 효율적인 실행계획을 구하기 위해서 질의의 선택율을 추정한다. 일반적으로 애트리뷰트들은 서로 독립적이지 않기 때문에 여러 개의 애트리뷰트를 가지는 질의에 대해서는 다차원 선택을 추정 기법이 필요하다. 대부분의 상용 데이터베이스에서는 히스토그램이 계산 오버헤드가 많지 않고 작은 에러율로 데이터 분포를 를 근사 시킬 수 있기 때문에 실용적으로 많이 사용되고 있다. 그러나 여러 개의 애트리뷰트를 가진 다차원 지?l의 경우에서는 차원이 높아 질수록 에러율을 낮추기 위해 많은 저장 공간을 필요로 하기 때문에 히스토크램 방법이 적합하지 않다. 이 논문에서는 다차원 선택을 추정을 위한 새로운 기법을 제안한다. 다차원 공간에서 크기가 작은 히스토그램 버켓을 많이 만들고 이 버켓의 정보를 DCT로 압축하여 선택을 추정에 사용함으로써 에러율을 작게 하고 저장 공간의 사용량도 줄인다. 폭 넓은 실험 결과는 본 논문에서 제시한 방법들의 타당성과 이점을 확인시켜 준다.
