Gasoline that meets the quality standards is distributed in Korea. However, consumers who use toluene or solvent mixed with gasoline have appeared due to rising crude oil prices and for the purpose of tax evasion. Gasoline quality standard is enacted by the domestic and international research reference. A wrong fuel can influence automobile performance or environmental issue. Thus, empirical data from this issue is necessary. Therefore, this research observed catalyst influence by gasoline property change and inspect influence of environment. In this study, fuel property evaluation, lean-burn evaluation, and real vehicle exhaust emission test were performed. In the result of fuel property, the fuel "A" was measured to be up to 27% less octane than the normal gasoline and the distillation property was measured 24% higher than normal gasoline. In the test result of single cylinder engine lean-burn test, the fuels "A" and "B" show torque value 20% less than the normal gasoline. As a result of vehicle test using the catalyst, the fuel "A" was increased more than the normal gasoline with 83% THC, 1,806% CO and 128% NOx, and the fuel "B" was increased more than normal gasoline with 1.6% THC, 391% CO and 142% NOx.

The purpose of this study is to find out the factors that explain the sense of touch and preference of man-made leather. Date base of descriptors for man-made leather was collected by interviewing 50 consumers, 33 different kinds of commercial man-made leathers(synthetic leather and artificial leather) were assessed subjectively by 605 consumers using the 9-point scale of 34 pairs of bipolar descriptors based on the data base. Subjective ratings were analyzed by principal axis factoring with varimax rota-tion. The sense of touch of man-made leather is explained by five factors ; surface property stretchiness thickness& weight thermal property(warmth & coolness) and moisture property (sticky & clingy). The difference in the sense of touch of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leather is explained by three factors ; surface property stretchiness and quality. Higher preference is found in man-mad leather of better quality touch and softness.

This study was conducted to improve sensory quality of Jokbal (Korean Pettitoes) made from frozen pig feet by addition of herbal mixture (glasswort, raspberry and Sansa powders). After adding herbal mixture, lipid oxidation (2-thiobarbituric acid values, TBARS), sensory property, and textural property were determined. Herbs were individually added into cooking soup at concentration of 6% (low concentration treatment, LCT) or 12% (high concentration treatment, HCT) of raw pig feet. Refrigerated pig feet were used as control. Thawed feet without any herbal mixture were used as freezing treatment (FT). TBARS in LCT or HCT were lower than that in FT, and showed the similar to that in Control. Addition of the herbal mixture was effective in improving the flavor and textural property of thawed feet by inhibiting lipid oxidation and protein denaturation in a dose-dependent manner.

While the pavement design is based on mechanical property such dynamic elastic modulus, the quality of highway subgrade during construction is controled by the optimum moisture content(OMC) and maximum dry density(${\gamma}$$\_$dmax/). However, since the quality control based on the OMC and maximum dry density does not consider the mechanical characteristics, there is a conceptional gap between design and PMS(pavement management system). Therefore, it is necessary to develope a new qualify control system using mechanical property for highway construction in more rational way. To achieve this goal, it is planned to perform various laboratory tests to collect mechanical properties of subgrade soil samples from several highway construction sites and to propose the relationship between dry unit weight (or OMC) and mechanical parameters. In this paper, the experimental data so far obtained are presented and analyzed. In addition, further research plan is presented and discussed.

Technology-oriented national R&D programs produce intellectual property as their final result. Patents, as typical industrial intellectual property, are therefore considered an important factor when evaluating the outcome of R&D programs. Among the main components of patent evaluation, in particular, the patent right quality is a key component constituting patent value, together with marketability and usability. Current approaches for patent right quality evaluation rely mostly on intrinsic knowledge of patent attorneys, and the recent rapid increase of national R&D patents is making expert-based evaluation costly and time-consuming. Therefore, this study defines a hierarchy of patent right quality and then proposes how to quantify the evaluation process of patent right quality by combining text mining and regression analysis. This study will contribute to understanding of the systemic view of the patent right quality evaluation, as well as be an efficient aid for evaluating patents in R&D program assessment processes.

Though the physical environment of life through technological evolution has rapidly improved, the quality of life due to a variety of undesirable environmental issues has been seriously damaging. This study has tried to suggest the positive & sustainable direction of space design which can contribute to improving the quality of human lives by reviving 'place property' which a site itself has, trying to analyze the recycling space which the sustainability has been applied to in a true sense. For this cause, we've tried to draw four 'methods of realizing place property' such as meeting a site, understanding a site, finding the identity of a site, and adding novelty to a site through advanced research. I've tried to suggest the design direction for reviving space which can relieve the artificial aspect of design with pursuing the co-existence with nature on the foundation of realizing 'place property' through case analysis selected on the basis of this, and can express the 'sustainability' through environment-friendly space structures & high efficiency of its function.
