The objective of this study was to explore the role of familiarity in cross-cultural product perception and perception changes according to food systems (hot sauce and spicy-chicken) in Korean and US consumers. Free choice profiling was conducted by Korean and US consumers on four spicy-chicken samples made using four hot sauce samples. Half of the hot sauce samples were selected to be more familiar to US consumers and vice versa to Korean consumers. A previous study that investigated cross-cultural perceptions of the same four hot sauce samples in US and Korean consumers was incorporated in this study. For distinct sample differences, US and Korean consumers perceived products similarly. However, for less obvious differences, flavor familiarity seemed to affect consumers' product perceptions. In addition, product perceptions changed more dramatically according to food systems for familiar samples in each country. The findings of this study show that consumers' product perception can be affected by flavor familiarities.

The purpose of this study is to identify selection attributes, functional benefits, psychological benefits, and values according to crossover shopping patterns (showrooming and webrooming). To achieve objectives of this study, a survey was designed based on the means-end chain theory, using the in-depth laddering technique and APT laddering technique which understanding the linkage of A(attributes)-FB(functional benefits)-PB(psychological benefit)-V(value). These two laddering techniques were used to construct a hierarchical value map (HVM) by linking selection attributes, functional benefits, psychological benefits, and value levels. The selection attribute items that showrooming shoppers consider important are 'price conformity', 'product information', 'product variety', and 'delivery service'. Functional benefit items were 'free purchase', 'economic benefit', 'communication', 'safety', and 'accurate Information', and psychological benefit items were 'convenience', 'relaxation', 'pleasure', 'rational consumption', and 'stability'. Finally, the value items were 'self-satisfaction', 'abundant life', 'achievement', 'happiness', and 'reasonable life'. Next, the selection attribute items that webrooming shoppers consider important are 'price conformity', 'product information', 'product variety', 'AS', 'shopping atmosphere', and 'seller service'. Functional benefit items were 'free purchase', 'economic profit', 'expression opinion', 'safety', and 'accurate information', and psychological benefit items were 'convenience', 'relaxation', 'rational consumption', and 'stability'. Finally, the value items were 'self-satisfaction', 'abundant life', 'happiness', and 'reasonable life'.

Pb-free wave soldering process of AC Adapter was implemented by six sigma method using Sn-Cu-Ni type solder. The solder joint appearance, microstructural change, a lift-off phenomenon and reliability were evaluated through thermal shuck test. $(Cu,Ni)_6/Sn_5$-type intermetallic compound of which thickness is about 5 $\mu\textrm{m}$ was found at solder joint between Sn-Cu-Ni solder and copper land. After applying the thermal shock test of as-soldered product up to 750 cycles, no crack was fecund at the solder joint. The newly developed product was superior to conventional one in terms of productivity and reliability.

This study was undertaken to evaluate the antioxidant potential of A. lanata on oxalate mediated free radical toxicity in ethylene glycol induced calcium oxalate urolithic rats. Calcium oxalate (CaOX) stone was induced by 0.75% ethylene glycol in drinking water for 28 days. From $29^{th}$ day onwards, the CaOX urolithic rats were treated with A. lanata aqueous suspension (2,000 mg/kg body weight/dose/day) orally for another 28 days. At the end of experimental periods the animals were sacrificed, samples were collected and analyzed the lipid peroxidation product, protein oxidation product, enzymatic and non-enzymatic antioxidants in normal and experimental groups. Lipid peroxidation and protein oxidation products were significantly elevated while enzymatic and non-enzymatic antioxidant levels were significantly decreased in ethylene glycol induced CaOX urolithic rats when compared with control rats. The above alterations were reverted to near control in rats treated with aqueous suspension of A. lanata. This study suggests that A. lanata could prevent the free radical formation from calcium oxalate urolithiasis in rats and protecting the renal cells from oxidative injury.

Recently, various plastics are used for improvement of reliability and thermal stability of electronic goods. But, it is difficult to choose suitable balance of grade resin to each other product property. Selection of high efficiency resin is becoming inescapable circumstance according to change of reflow temperature of product and development of product following to lead free. Using a inexpensive and reasonable resin, that sustain a uniform performance of product quality. It is make a robust product and increase a company's competitive power. Hereupon, I introduce example that use ESPI methods of thermal deformation analysis of product using in our company product. I try to refer to a structural weak point detection of real time measurement of electronic parts instead of mechanical and chemical measurement of specimen type.

The effects of time delay between a video signal and a current signal applied to velocity modulation coil on free-spot movement and beam size were measured and analyzed quantitatively in this study. The result shows that it is the most important to avoid signal mismatching in order to achieve the optimal velocity modulation performance.

In order to contribute to trial of the ocean weather forecasts, we have developed new generation sea surface temperature. It is clod free, high-spatial resolution daily SST product, which enables us to follow the movements of SST patterns relating to the oceanic variations. The product is produced through an objective analysis merging various infrared and microwave SST products.

At present, Electronic industries push ahead to eliminate the Pb(Lead) -a hazardous material-from all products. Especially, we have performed to select the optimum standard composition of lead free alloy for the application to products for about 3 years from 2000. These days, we have the chance for applying to the mass-production. This project constructed the system for applying the lead free solders on consumer electronic products, which is one of the major products of the LG Electronics. To select the lead free solders with corresponding to the product features, we have passed through the test and applied with Sn-3.0Ag-0.5Cu alloy system to our products, and for the application to the high melting temperature composition, we secured the thermal resistance of the many parts and substrate and optimized the processing conditions. We have operated the temperature cycling test and the high temperature storage test under the standards to confirm the reliability of the products. On these samples, we considered the consequence of our decision by the operating test. For the long life time of the product, we have operated the temperature cycling test at $-45^{\circ}C\;-\;+125^{\circ}C$, 1 cycle/hour, 1000 cycles. Also we have tested the tin whisker growth about lead free plating on lead finish. We have analyzed with the SEM, EDS and any other equipment for confirming the failure mode at the joint and the tin whisker growth on lead free finish.

Serum is a potential source of bacterial, mycoplasmal and viral contamination, and it has a possibility of the introduction of serum proteins, prion and pyrogens into the final vaccine product. For porcine Rotavirus vaccine production, it is necessary to develop serum free medium which do not cause those problems. A new serum free medium was developed for porcine Rotavirus vaccine based on DMEM, and the performance of developed serum free medium was evaluated in terms of Vero cell growth and Rotavirus vaccine production. The cell density, gown in serum free medium developed, was similar with that in serum supplemented medium. Also, it was higher than that in other commercially available serum free medium. The productivity of Rotavirus vaccine using serum free medium developed and optimum production strategies will be also discussed.

Due to the recent growth of die/mold machining industry, demands for the high-precision and the high0quality of die product are increasing rapidly. Free surfaces of die/mold are often manufactured using the ball-end milling process. It is difficult to find the cutting condition of the ball-end milling process due to the free form machining for the various tool paths on inclined surface.
