A Korean seasoned meat product, seasoned bulgogi was developed in processing and packaging for improved convenience and extended shelf life. The optimal process conditions were found to consist of aging for $20{\sim}30$ hours at $5^{\circ}C$ and air heating for 20 minutes at $210^{\circ}C$ Aging of 24 hours could attain soft texture with little change in pH, color and total aerobic bacterial count. Appropriate drip level could be achieved at air heating of 20 minutes at $210^{\circ}C$, while the air heating at $180^{\circ}C$ could not give suitable level of texture. Modified atmosphere packaging of 60% $CO_2$ and 40% $N_2$ could preserve the product significantly better compared to control of air package and vacuumed package.

Beverage industry is the largest in the domestic packaging market. Usually, beverage is packed in palstic, glass, can and paper bags. However, the cost of these packaging methods are very high and the recycling are not easy to handle. Pouch packaging method is one of the packaging method to solve the drawbacks of former beverage containers. The pouch packaging methods are difficult to control, it requires a number of processes. A vertical form-fill-seal machine which is self-developed is the capable of processing in a single apparatus. In this paper, in order to develop a pouch equipment, the structure analysis was carried out for the main unit. The stress and deformation of feed unit which removes the air inside the pouch while feeding down has been analyzed. It receives the greatest impact from the rolling part. And also, the sealing unit has been analyzed. The analysis result shows that the stress and the deformation was slight to be applicable to the actual system.

In order to obtain basic data on the shelf life of Epimedii Herba (EH), a physicochemical characteristics including weight loss rate, loss on drying, ash, acid-insoluble ash, and quantitative determination were evaluated to compare the data by packaging methods including general (G), general + silica gel (GS), alumium (AL), and alumium + silica gel (ALS) packaging and storage periods (0-66 months). All physicochemical analyzes were conducted using the method of "The Korean Pharmacopoeia (KP) 9^th edition". As a result, weight loss rate (%), loss on drying (%), ash (%), acid-insoluble ash (%) of EH according to the packaging methods and storage periods were -0.27-4.73%, 3.06-9.35%, 5.48-7.37%, and 0.45-0.99, respectively. In the quantitative analysis of icariin, the marker compound of EH using high-performance liquid chromatography, the initial content was 0.44% at 0 month in all packaging methods. After that, the result of analyzing the content of icariin every 6 months was detected 0.44-1.18%. All of the above results satisfied the acceptance criteria for loss on drying, ash, acid-insoluble ash, and quantification contained in the KP. This study can be used as a basic data for establishing the packaging method and shelf life of EH.

This study was carried out to measure and analyze the storage condition, distribution route, and packaging method of four selected agricultural products(small tomato, cabbage, peach, and carrot) in the cold chain system. It was shown that dew-forming phenomenon by fruits and vegetables deteriorates the agricultural product quality and physical properties of corrugated fiberboard box during the cold chain system. The compressive strength deterioration in corrugated fiberboard boxes was much greater for single wall(SW) corrugated fiberboard containers than for double wall(DW) in low temperature-high humidity condition. To reduce the deterioration of box and dew-forming phenomenon, water-repellency treatment should be over $R_6$. However, water-resistant treatment of corrugated fiberboard containers would be effective under high relative humidity conditions more than 75% RH. It was suggested that functional corrugated fiberboard box packaging would be an optimum method to reduce the deterioration of agricultural products quality by. It was also achieved controlling the relative humidity and temperature during the storage and physical distribution process.

본 연구는 천적 곤충을 운송하는 동안 제품의 품질을 유지할 수 있는 포장 표준화 방안을 마련하고자 수행되었다. 먼저 4개 업체의 천적 제품 유통 현황을 분석한 결과, 평균 배송 소요시간인 36 ~ 48시간동안 평균 25.6℃(최저온도: 18.1℃, 최고온도: 30.7℃)를 유지하는 것을 확인하였다. 계절별 최적의 포장방법을 구축하기 위하여 0 ~ 30℃ 범위에서 5℃ 간격으로 7개의 외부온도조건을 설정하였다. 또한 보냉제의 취급방법별 내부온도 유지성능평가를 실시해 14건의 포장조합을 도출하였다. 도출한 포장조합을 외부온도조건에 맞춰, 포장 후 12시간 이내의 직접 배송 또는 36 ~ 48시간이 소요되는 일반 배송기간 동안 최소한의 에너지로 천적의 생존을 유지할 수 있는 발육영점온도에 근접한 3.0 ~ 9.9℃로 유지할 수 있는 포장조합을 제시하였다.

The ultrasonic bonding method and its feasibility are investigated in this work for joining the micro components and MEMS packaging. The ultrasonic bonding process is analyzed using a lumped mode, and preliminary experiments using the eutectic solder and copper pin were carried out to verify possibility to MEMS packaging. The ultrasonic bonding process appears to be adequate for MEMS packaging by providing localized heating at the selected area. Microscopic behavior of the bond joint through ultrasonic vibration needs further investigation.

Processing steps such as washing and cutting, involved in preparing fresh-cut produce causes tissue damage, leading to rapid quality deterioration. Major defects of fresh-cut produce are discoloration, softening, off-odor development, and microbial growth. Packaging of fresh-cut produce has been changed to reduce these quality problems. Flexible packaging film is widely used to pack fresh-cut produce. Vacuum packaging was the popular packaging method in the beginning of fresh-cut industry in Korea. Vacuum packaging creates high $CO_2$ and low $O_2$ levels to control browning of fresh-cut produce. However, these conditions induce some visual defects and off-odor development. Discoloration problem was also found when fresh-cut produce was packaged with conventional packaging film or plastic tray. Modified atmosphere (MA) packaging is effective for prolonging shelf-life of fresh-cut produce by decreasing $O_2$ and increasing $CO_2$ concentration in the package. Retail MA packaging using different oxygen transmission rate (OTR) film and micro-perforated film has started to be applied to fresh-cut produce in Korea. Proper MA package design that provides optimum range of $O_2$ and $CO_2$ partial pressures is one of the major challenges in the industry. An initial package flushing with $N_2$ or an low $O_2$/high $CO_2$ atmosphere is also used to more rapidly establish steady-state MA condition. Film OTR and $O_2$ flushing affects the fermentative volatile production, off-odor development, electrolyte leakage, discoloration, $CO_2$ injury, microbial population of fresh-cut produce. There is also a demand for convenient packaging to attract consumers. Rigid fresh-cut produce container for retail market has increased since the packaging provides excellent protection from physical damage during transport. Rigid tray used as actual serving vessel for the consumer is increasing in Korea. The tray with flexible lid to wrap or seal fresh-cut produce is more and more gaining popularity. Further practical technology to control quality change and microbial growth for each fresh-cut product has been studied since various fresh-cut items were required. The fresh-cut industry also focuses on searching for more convenient and environmentally friendly packaging.

The method to characterize the fresh produce respiration was presented with possible application of modified atmosphere package design. Particularly the respiration model based on enzyme kinetics was introduced as function of oxygen and carbon dioxide concentrations. The method to estimate the equilibrated package atmosphere for any package conditions was presented by incorporation of $O_2$ and $CO_2$ permeabilities of the packaging film. Temperature dependences for fresh produce respiration and gas permeation were given by Arrhenius equation and then used to analyze the effect of temperature on the package atmosphere. An example analysis was presented for better understanding of the concept.
