This study intended to determine how price-ending types used for menu products affected consumers' price evaluation and value perception and such behavioral intentions as purchase intention and search intention. The collected data went through statistical processing, including frequency analysis, factor analysis, T-test and ANOVA using an $SPSS/PC^+$ 12.0 statistical package. The results can be summarized as follows: First, as for differences in internal reference price by ending, internal reference price was lower if menu ending was an odd number than it was an even number, which indicates that consumers tend to consider the price of the menu products to be lower if the ending of menu products is an odd number. Second, menu price-ending was found to have significant differences on consumers' purchase intention, search intention, and value perception. But the results of two-way ANOVA showed that price ending by restaurant types had no effect on consumers' search intention and restaurant type. This study suggested a desirable external reference price-ending type for menu products as one of sales promotion strategies to menu products planners and drew up a concrete plan to determine which price-ending type is useful by consumers' personal properties.

Packaging is thought to contribute to the consumers' purchasing choice of the powdered infant formula products. In Asian market, the products of international and local brands are competing. Evaluation and analysis of food package functions for a variety of brand products will be helpful for the innovative packaging development. Thus, the packaged products of powdered infant formula were collected in Chinese, Indonesian and Korean supermarkets as a typical Asian market and examined in terms of main food packaging functions. Metal cans were the most dominant type of big size package (800-1000 g) while flexible bags were often the common one of medium size (400 g). In general, convenience function was provided in forms of easy opening device and portioning take-out spoon. Information on primary and secondary shelf lives was given besides nutritional facts and use instruction for communication function. The combination of $N_2$ and $CO_2$ was usually employed to protect powdered infant formula in rigid packages, whereas only $N_2$ was used to protect product in most flexible packages.

The work focuses on the development of a Cu lead-frame with a single-sided adhesive tape for cost reduction and reliability improvement of LOC (lead on chip) package products, which are widely used for the plastic-encapsulation of memory chips. Most of memory chips are assembled by the LOC packaging process where the top surface of the chip is directly attached to the area of the lead-frame with a double-sided adhesive tape. However, since the lower adhesive layer of the double-sided adhesive tape reveals the disparity in the coefficient of thermal expansion from the silicon chip by more than 20 times, it often causes thermal displacement-induced damage of the IC pattern on the active chip surface during the reliability test. So, in order to solve these problems, in the resent work, the double-sided adhesive tape is replaced by a single-sided adhesive tape. The single-sided adhesive tape does net include the lower adhesive layer but instead, uses adhesive materials, which are filled in clear holes of the base film, just for the attachment of the lead-frame to the top surface of the memory chip. Since thermal expansion of the adhesive materials can be accommodated by the base film, memory product packaged using the lead-flame with the single-sided adhesive tape is shown to have much improved reliability. Author allied this invention to the Korea Patent Office for a patent (4-2000-00097-9).

The brand sound of vehicle diesel engine is recently one of the important advantage strategies in the automotive company. Because various noise components masked under high frequency level can be audible in quieter driving situation. Many researches have been carried out for subjective and objective assessments on vehicle sounds and noises. In particular, the interior sound quality has been one of research fields that can give high quality feature to vehicle products. Vehicle interior noise above 500 Hz is usually controlled by sound package parts. The materials and geometries of sound package parts directly affect on this high frequency noise. This paper describes the sound quality evaluation method for the vehicle diesel engine noise to establish objective criteria for sound quality assessment. Considering the sensitivity of human hearing to impulsive sounds such as diesel noise, the human auditory mechanism was simulated by introducing temporal masking in the time domain. Furthermore, each of the human auditory organs was simulated by computer codes, providing reasonable analytical explanations of typical human hearing responses to diesel noise. This method finally provides the sound quality index of vehicle diesel engine noise that includes high frequency intermittent offensive sounds caused by impacting excitations of combustion and piston slap.

This study analyze the willingness to pay for customized agricultural products to diabetes. For this purpose, a survey was carried out for patients with diabetes 212 patients. The main results are as follows. First, the survey found that the interest in health and food was found to be very high in 93.9 % and 85.9 % respectively. This means that there is sufficient market potential if customized food and diets for diabetes are developed. Second, the Logit analysis showed that influential factor for the willingness to pay for a customized diet. The higher the risk, the better the health outcomes, the higher the likelihood that the higher the level of income, the more likely it is to purchase a product for a diabetic food package. Third, the average amount of willingness to pay for the customized food for diabetes patients was 7,823.5 won and the truncated average value was 6,953.3 won.
