This study examined green consumption behavior according to the lifestyles of college students. The data were collected from 314 college students in Yeungnam region by a self-administered questionnaire. Frequencies, Cronbach's alpha, factor analysis, cluster analysis, chi-square tests, one-way analysis of variance, Duncan's multiple range tests, Pearson's correlation analysis, and multiple regression analyses were conducted by SPSS Windows V.18.0. According to the result of factor analysis, lifestyles were categorized into six factors: thrift-saving type, enthusiastic activity type, brand ostentation type, freedom-seeking type, material oriented type, and practice-seeking type. Cluster analysis showed respondents belonged to one of four groups: thrift practice group, indifference group, freedom-seeking group, and material ostentation group. The levels of green purchase behavior, green usage behavior and green disposal behavior of the respondents was not high. The thrift practice group showed higher levels of green purchase behavior, green usage behavior, and green disposal behavior. Finally, according to multiple regression analyses, environmental consciousness, knowledge about green consumption, lifestyle groups were the significant factors affecting green consumption behaviors. These results imply that green consumption education for college students should be activated to induce green life.

The purpose of this study was to investigate how the financial satisfaction of housewives was related with the financial condition of households and the performance evaluation of household financial management behavior. In order to examine this relationship, internet questionnaire survey was conducted with 598 housewives. Results showed that household income and monthly debt repayment had only indirect effects on the financial satisfaction while monthly saving had both of the direct and indirect effects. It indicates that financial satisfaction level varies with the perceived performance of financial management behavior even though they have the same level of financial resources. Specifically, the division of financial roles and problem solving style between husband and wife affected the financial satisfaction of housewives.

Conventional traffic assignment techniques usually do not consider traveler's route choice behavior affected by hierachicla strucfture in urban highway system. This study realizes the route choice behavior such that travelers tend to choose more higher level of highway rather than lower level of highway for longer trops. Otherwise, for shorter trips, travelers tend to choose lower level of highway unless they can get sufficient travel time saving by using mojor arterial street or freeway (higher level of highway). Therefore, this study suggests a traffic assignment technique incorrporating route choice behavior related to hierachical highway structure by introducing some perception costs to generalized cost function such as perceptional preference measureemnt for higher level higheay and perceptional penalty when changing to different level of highway. Through simulation analysis, it is shown that the simulation results with the new traffic assignment echnique can be different a lot from the results with the convential method.

The response to climate change of international air transport industry might be initiated by ICAO's CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) which will impact on international airlines' flight operation behavior in the future. Though the airlines' efforts to reduce fuel consumption has been a major issue in economics of aviation industry, the improvement of fuel efficiency in flight operation will have additional impact on their profitability by introducing carbon emission cost. The fuel consumption in flight operation will be somewhat influenced by pilots' technical action for maneuvering aircraft during flight operation. This study will investigate pilots' behavior on decision for tactical aircraft control for mission flight. The data will be collected by the survey through sample pilots asking about their intention and perception on fuel savings during flight operations. The data will be analyzed by AHP process and the study will find out the elements and factors influencing pilots' behavior on technical decision of flight and their weights on fuel saving effects.

The purpose of this study is to investigate dining out behavior of college student living in jeju. The data obtained from 533 questionnaires returned by college student. 36.9% of students indicated over-eating, 27.2% did skipping meal, 14.8% did unbalanced diet, and 11.3% did indulging in hot and spicy food as dietary problems of food habits. Many students consumed 5,000-10,000 won/one time. In the breakfast 63.6% of students did not eat out, in the lunch only 10.5%, and in the dinner only 1.7% did not. The students ate out to take a meal in the breakfast, to meet their friends in the lunch, and to meet their friends and to haute social meeting in the supper. They considered intake nutrition and time saving in the breakfast when they ate out. But in the lunch they had various purposes- intake nutrition, time saving, making with relationships, and enjoying taste of foods. In the supper two-thirds of students considered promoting friendship. The satisfaction of eating out was different significantly from types of living and length of mealtime.

This analytical study was carried out to make quality and productivity up in designing the frame-type furniture with semi-rigid joint by understanding the mechanical and structural behavior of the joint and by evaluating the validity of application of the time-saving Finite Element Method to its structural analysis. Slope deflection equation for rigid joint was modified to describe the moment-rotation behavior of semi-rigid joint and the joint stiffness factor(Z) could be calculated to lessen the experimental expense. It was proved that Finite Element Analysis with imaginary elements having equivalent MOE to the semi-rigid joint could be the alternative method for the structural analysis of the frame-type furniture, comparing the internal rotation of the 2-dimensional beam-to-column model with two-pin(wooden dowel) from the finite element method with other available theoretical and experimental rotation value.

Cast-forging process has a lot of advantages in terms of saving materials along with enhancement of mechanical properties. Therefore, this process has been taken as one of candidate process to manufacturing automotive suspension parts. Since most of cast-forging parts are made with using Al-Si alloys of high castability, the mechanical properties largely depends on the primary ${\alpha}$ and eutectic Si particles. During hot forging step these microstructural features evolve with strain increment. In the present study, the mechanical property evolution was investigated in terms of microstructual evolution with strain. Specially, fracture behavior of A356 alloy was studied to find out how to improve the mechanical properties.
