Beetles belonging to the families Scolytidae, Platypodidae, Bostrichidae, and Lyctidae intercepted from imported timbers at Busan port were investigated from March 1 to November 30 in 2000. In addition, hosts imported country were examined. A total of 52 species of within 23 genera was intercepted from nineteen species of timbers or logs from fifteen countries. In Scolytidae, 35 species of 16 genera in three subfamilies were identified 12 species in Xyleborus, 6 species in Ips, 3 species in Trypodendron, 2 species in Arixyleborus, and 12 species of all different genera including Alinphagous. Scolytidae were intercepted from 16 species of timbers in 13 genera imported from 11 countries. The highest beetles were intercepted from Malaysian lauan. In Platypodidae, 9 species of one genus (Platypus) were intercepted from 6 species of timbers in 4 genera imported from 6 countries including Australia. The highest numbers were intercepted from Malysian lauan. In Bostrychidae, 5 species of 4 genera in two subfamilies were intercepted from 6 species of timbers in 4 genera imported from four countries. In Lyctidae, Trogoxylon sp., Minthea sp., and Minthea rugicollis were intercepted from 3 species of timbers in 2 genera imported from 3 countries.

This study provides product survey data for the development of medical compression stockings. An investigation analyzed imported medical compression stockings of 40 brands from 6 countries sold in the Korean market, such as Jobst$^{(R)}$, Therafirm$^{(R)}$, Rxtar$^{(R)}$, Varicoin$^{(R)}$, and Sheer&Soft (USA), Sigvaris Venosan$^{(R)}$ 4000 (Switzerland), Best$^{(R)}$ and Segreta$^{(R)}$ (Italy), Venex$^{(R)}$, Star cotton, Doktus$^{(R)}$, Maxis$^{(R)}$, Maxis$^{(R)}$ Cotton, Lastofa$^{(R)}$, and Memory Aloe Vera (Germany), and Gunze (Japan), Venos and Yolanda (Taiwan). The main fibers of compression stockings were nylon and spandex; in addition, the fiber content was different by country and brand. The number of compression classes of imported products was USA (5), Italy (5), Germany (4), Switzerland (3), Japan (3), and Taiwan (3). For basic body measurements, USA and Swiss brands used ankle circumference, calf circumference, thigh circumference, calf length, and thigh length. Italian brands used height and weight, and Japanese brands used height and hip circumference. German brands used subdivided circumferences such as ankle circumference, calf circumference, knee circumference, middle thigh circumference, and thigh circumference.

Total fatty acid compositions, total content of crude fat, saturated, unsaturated and trans fatty acid content were studied in children's favorite foods such as hot dog, chicken popcorn, fried potato, snack and cookies, and imported biscuit. The samples were obtained from various stores in Daejeon. After fat extraction, methylation was carried out to analyze the fatty acid compositions by gas chromatography. The results showed that content of the trans fatty acid per 100 g of the hot dog, chicken popcorn, fried potato, snack and cookies, and imported biscuit were 0.02~0.03 g, 0.05~0.08 g, 0.02~0.05 g, 0.02~0.27 g, and 0.05~0.83 g, respectively. The highest content of saturated fatty acid (66.24%) was observed in the imported biscuit among the 20 analyzed samples.

Up to date several mycoviruses including Lentinula edodes Spherical Virus (LeSV) have been reported. As fungal virus was spreaded by infested hypae and spores it could be important to use virus-free spawns to eradicate the mushroom virus disease in the culture farm. We tested the imported spawns of Lentinula edodes by PCR whether LeSV was infested them or not. The primer set targeting the RdRp gene of LeSV was prepared based on partial sequence of the LeSV genome. The RT-PCR analysis showed that 87 among 88 imported spawns of L. edodes were infested by LeSV.

The purpose of this study was to classify the consumption values of 20's and 30's female consumers, identify the differences among the consumption value groups, and analyze purchase behaviors of imported fashion luxury brands according to the consumption value types. The subjects were 518 women who purchased luxury bags. The results of the study were as follows. First, as a result of cluster analysis to classify the consumption values of 20's and 30's female consumers, 4 groups were identified as "rare and emotional pursuit group", "functional pursuit group", "fashion pursuit group", and "social and conspicuous pursuit group". Second, 4 groups showed different luxury bag purchase behaviors, such as purchase motivation, purchase selection criteria, information source, purchase frequency, purchase cost of one time, purchase cost of year, the number of possession, purchase place, and store selection criteria. Third, rare and emotional pursuit group ranked the first in terms of product, price, and store satisfaction. Therefore, consumption values were identified as the important factor suggesting purchase behaviors of female consumers in 20's and 30's.

This study aims to examine the consumer preference for packaged bean curd that takes a growing public interest. Specifically, this study tried to examine which is more important - the place of origin of the raw bean or the environmental-friendliness of the raw bean. Surveys were conducted to obtain information, such as the consumer evaluation for food safety on imported food products from China and the consumer perception of Chinese organic food products, Using the binary probit model, the relationship between consumer's choice of packaged bean curd and potentially important factors that can affect the consumer's choice was analyzed. A summary of this research and some policy implications follow. The results of this study can be used as the basic guideline as to how to extend the safety of imported food products, in general, and how to further develop the packaged bean curd industry in Korea, in particular.

This study was carried out to discriminate Hanwoo from the milking and hybrid cattle by detection of MC1R gene related to bovine hair color. One hundred sixty six samples were collected from the abattoir (n = 106) and local market (n = 60). The beef from abattoir were originated from Hanwoo (n=27), Holstein (n=29), Hybrid (n=45) and imported cattle (n=5), respectively. The beef from market consisted of Hanwoo (n=36), Holstein (n=7) and imported ones (n=17). Commercialized screening kit (Kogenebiotec, Korea) was used for MC1R gene analysis. As a result, Hanwoo was discriminated from Holstein. However, 9 of 45 hybrid and 11 of 22 imported beef samples were indistinguishable from Hanwoo. It could be explained by second generation of crossing of Hanwoo with Holstein or the cattle with silver or yellow hair. This results suggest that additional tests as well as MC1R gene detection be needed to confirm Hanwoo beef among cattle beef.

The geographical origin of Tricholoma matsutake mushrooms was studied using near-infrared spectroscopy. Modified partial least-square regression analyses were used to discriminate geographical origin. Two-hundred fifty-six of 259 actual domestic Tricholoma matsutake were classified as domestic produce, Sixty of 81 actual imported mushrooms were correctly classified as imported, while the other 21 imported from North Korea were not clearly classified. The accuracy of geographical origin discrimination was 92.94% The correlation coefficient, standard error of calibration, and standard error of prediction from modified partial least-square regression analysis were 0.84, 15.10% and 18.30% respectively.

The practicality of utilizing chitosan as a natural antimicrobial compound to reduce soybean sprout rot was tested. Domestic and imported soybean seeds were soaked for 6 hours in solutions containing different levels of chitosan and acetic acid (glacial), and cultured at $25^{\circ}C$ for 6 days. In case of domestic seeds, soaking with 1,000ppm chitosan increased germination percentage, hypocotyl thickness, total length, and fresh weight of sprouts by 4%, 5%, 2%, and 1%, respectively. The total sprout yield was increased by chitosan in a concentration-dependent manner in that 1,000ppm chitosan resulted in 8% increment of total yield (7.47kg sprouts/kg seed). Chitosan significantly reduced sprout rot percentage to 7.0% compared to control (13.8%), and consequently enhanced marketable sprout yield by 39%. Compared to domestic seeds, the imported soybean seeds exhibited very low germination percentage regardless of chitosan treatments. Chitosan, nevertheless, consistently induced yield increment and rot decrement in imported soybean sprouts. Although 100ppm acetic acid was effective in reducing sprout rot percentage down to 11.8%, its yield-increasing effects were not as prominent as chitosan. In conclusion, soaking soybean seeds with chitosan seems to be a practical method to enhance the efficiency of soybean sprout production.
