Various commercial collagen mixtures aimed at improving the quality of meat products are available, but the optimal composition is unclear. This study aimed to compare the functional properties, including physicochemical characteristics and lipid oxidative stability, of loin ham marinated with three commercial collagen mixtures sold as food additives. The addition of collagen mixtures led to significant increases in the moisture content, water holding capacity (WHC), cooking yield, and instrumental tenderness, regardless of the type of collagen mixture. In particular, meat samples containing collagen mixture C showed the highest (p<0.05) WHC and tenderness among all groups. Furthermore, collagen mixture B induced increases (p<0.05) in pH values in both raw and cooked samples. The $a^*$ values of samples with collagen mixtures were lower (p<0.05) than those of samples without collagen mixtures. All collagen mixtures effectively improved oxidative stability during 7 days of storage at $4^{\circ}C$. The samples containing collagen mixture B had the lowest lipid oxidation (p<0.05) among groups. These results indicated that collagen mixture C could be used in injection brine to enhance the quality characteristics of meat products, particularly the WHC and tenderness. Collagen mixture A could be used for meat products with high fat contents based on its ability to improve lipid oxidative stability during long-term storage.

This study investigated and compared chemical properties and biological activities of four commercial sikhae products (three flat-fish, Pleuronectes herzensteini, Sikhae: product A, B, C; one Alaska pollack, Theragra chalcogramma, Sikhae: product D) and Alaska pollack Sikhae (product E). Total acidity, amino nitrogen, salinity and pH in all products were in ranges of $0.47-1.93\;g\%$, $145.94-204.81\;mg\%$, $3.40-4.00\%$ and 4.38-5.55, respectively. All products showed antimicrobial activities against Bacillus ceraus subtilis, B. cereus, Staphylococcus aureus, Listeria monocytogenes, Vibrio parahaemolyticus, except for Salmonella typhimurium. Particularly the activities were more effective with gram positive bacteria than gram negative bacteria. Antioxidative $(EDA_{50};\;14.20\;mg/mL)$ and Fibrinolytic (0.95 plasmin unit/mL) activities of product E were much stronger than commercial Sikhae products (EDA50; 18.87-34.60 mg/mL and 0.69-0.85 plasmin unit/mL).

상업 시설에는 다양한 상품을 진열하고 판매되고 있어 다양한 상품들 중 특정한 상품을 홍보하기가 매우 어려운 것이 현실이다. 그렇기 때문에 대부분의 진열된 상품의 정보를 홍보하기 위해서는 인쇄물이나 판매사원에 의존하는 경향이 크다. 따라서 매장에서 사용하고 있는 디스플레이를 활용하여 인터렉티브한 사용자 인지 정보를 기반으로 광고/홍보 영상 표출의 구현을 목적으로 두고 있으며, 상업 시설에서 판매/전시되고 있는 특정한 상품을 고객 접점에서 명확한 상품 및 컨텐츠를 홍보하길 원하는 제조업체 또는 광고업체에게 매우 유용하게 활용될 수 있는 기술이라고 판단된다. 본 연구에서는 일반 디스플레이가 아닌 투명 디스플레이를 활용하여 광고 영상과 제품의 결합을 통해 광고효과를 극대화하고 사용자 감응형 센서를 적용하여 사용자 인지 유무에 따른 인터렉티브한 서비스를 제공할 수 있도록 사용자 지향형 영상 표출 기술을 구현하였다. 이 기술 연구를 통해 다양한 상업시설에서 광고/홍보효과를 극대화할 수 있는 새로운 방향을 제시하였다.

본 연구에서는 다양한 고추 가공품의 capsaicinoids 함량을 분석하고 분석 방법을 검증하고자 하였다. 본 연구에서는 역상 HPLC를 이용하여 고춧가루 및 고추 가공품의 capsaicin과 dihydrocapsaicin의 함량을 분석하였다. 연구 결과 고춧가루 및 고추 가공품의 capsaicin 함량은 0.21~78.24 mg/100 g이었으며 dihydrocapsaicin 함량은 0.20~38.82 mg/100 g으로 나타났다. 고추장, 초고추장, 쌈장, 소스류에 비해 고춧가루의 capsaicin과 dihydrocapsaicin의 함량이 높게 나타났다. Capsaicinoids의 분석방법을 검증하고자 정밀도, 정확도, 특수성을 분석하였다. 그 결과 회수율은 90% 이상이 었으며 재현성과 반복성의 CV%는 5% 이하로 우수하게 나타났다. 전반적으로 분석 방법의 검증 parameter들은 우수하였다.

Fastener tapes are widely used as auxiliary materials in textile products, and military textiles products are also applied. However, in Korea, the HL3-WA class of KS K 1309 was applied to military uniforms without consideration of the operating environment. Instead of adopting the standard of initial strength for Korean military uniforms, the US military applied the value after 3 washings, and presented different properties according to the items. Also in Japan, the standard was applied differently according to products in general clothing. The purpose of this study in to examine the quality level of fastener tapes used for military materials. The changes of tensile shear strength and peel strength of military and commercial fastener tape were studied after washing. As a result, the initial strength of the current military fastener tapes was higher than commercial one, but the strength retention rate was rapidly decreased as the number of washing. So it was confirmed that the decrease in strength was relatively lower than commercial one. It is necessary to improve the durability by adjusting the adhesive strength to suit the purpose of the product, and it is necessary to consider the priority of maintaining the durability according to the initial performance and repeated use according to the use environment, respectively.

In this study, effect of freezing and cryogenic crushing on physico-chemical characteristics of sardine, pollack and sqiud representative for domestic frozen fishery products was investigated and some product using them was tried to be prepared. Dehead and viscerated, washed fishes were subjection to freezing without air circulation and liquid N2 gas at -20$\^{C}$,-40$\^{C}$ and -80$\^{C}$, and then frozen fishes were crushed by hammermill, masscolloider and the product was stored added with anti-freeze such as sorbitol, phosphates, starch and egg Powder, qualify of frozen squid surimi was not changes during 70 days at below -20$\^{C}$ . The results of quality characteristics and sensory evaluation of patties and nugget which made from shattered squid and pollack were similar to commercial products in flavor, color and texture, but sardine meat was inferior to commercial products in flavor and color.

Graphite is well known as a material which has high-temperature thermostable property, chemical resistance against acid and alkaline state also is very easy to environment. Nowadays the need of graphite product is increasing rapidly because of its advantages. In this paper, the mechanical property of newly developed graphite products with high density is investigated with especially in compression test. I introduced the graphite specimens for this study by NGF method with two expandable graphite and compared to the specimens of commercial graphite sheet from expanded graphite which made by the rolling process. I investigated the characteristics of these materials by measuring specific weight, hardness, compressive strength and investigating structures by SEM, It is verified that the graphite products with NGF method has superior properties for using gasket materials than that of commercial graphite sheet.

Isothiazolinone derivatives are widely used in consumer products as disinfectants or preservatives, but there are growing concerns about their impact on human health. Therefore, rapid screening of these biocides is very important for proper control and regulation of potentially hazardous substances. To this end, low-temperature plasma (LTP) ionization mass spectrometry (MS) was investigated to demonstrate its potential for direct and selective analysis of isothiazolinones from sprayed aerosol samples. Benzisothiazolinone (BIT) was clearly identified from a commercial fabric deodorant using LTP ionization MS and MS/MS. LTP allowed selective ionization of BIT directly from the simply sprayed aerosol sample and illustrated its potential for fast screening without sample pre-treatments. Selective nature of LTP ionization, on the other hands, implicates use of LTP ionization MS as a general screening method for specific groups of hazardous chemicals in commercial products.

The use of plastics in our everyday lives have been drastically increased during the last few decades. However with the usage of commercial plastic products there is a possibility of microplastic consumption, due to the fragmentation of the products. Additionally, the potential for microplastic ingestion may also be increased by using damaged products. Hence, the current study was conducted to understand the potential release of micro/nano plastics and organic matter from damaged teabags. To check the leakage tendency, the amount of damage to the tea bags from 1-10 cm were tested along with temperatures of 25-70℃, and exposure times from 5 min to 1 hr was tested. Release of fibrous micro/nanoplastics, and organic leachate from the damaged teabags were observed to understand the outflow conditions. Results showed that with the increased degree of damage, temperature, and exposure time increased the release of fiberous matter, where the increase of temperature, and exposure time increased organic leachate. Additional analysis confirmed the leachate of nylon polymers into the heated water.
