This study was carried on the preferences for food intake pattern of Korean industrial workers. The survey was conducted from Feb 17, to March 31, 1992 by questionnaires which was composed of 21 items. The subjects of this study were composed of 426 clerical workers, and 439 physical workers. The results were obtained as follows. 1. In the educational background, clerical workers was almost of highschool or collage graduates, and physical workers was almost of highschool graduates. Marginal food cost of per person for lunch a day was from 500 Won to 1,000 Won. They replied that amount of staple food and side dishes were appropriate, and the type of preferable foods was Korean style cooked rice. Also it was known that physical workers thought their nutritive condition more badly than that of clerical workers. So the physical workers considered their health very much when they had meal. It was represented that unbalanced diet, without diet and drinking alcohol effected badly to food intake and taste of food was the most important point in food intake. 2. Preferences for staple foods; Cooked rice was preferred the most by the subjects. Cooked rice with redbean was preferred by clerical workers and cooked rice with soybean was preferred by physical workers and cooked rice with soybean was preferred by physical workers. Also clerical and physical workers liked Kalkooksoo (hot noodle), Nangmyun (cold noodle), bread, vegetable bread and disliked Sphagetti, Ramyun (Instant noodle) in same rate. In the next, cooked rice covered with raw fish pieces (Sushi) was preferred by clerical workers and Mandu-kook was preferred by physical workers. Also they disliked Curriedrice and Hashrice in same pattern. 3. Preference for side-dishes; The Acceptances for side-dishes were high soybean paste soup (clerical workers:43.7%, physical workers:34.4%), Kim chi stew, fried potatoes, crab steaming (37.8%, 36.9%), broiled fish (34.6%, 33.9%), fried green pepper, Ham, Chinese cabbage Kim chi, and pickled garlic by clerical and physical workers all together. But in clerical workers, Wooghugi beef-rib tang, Deodeok muchim, spinach namul, beef jangjeorim, fried shrimp were shown to have high preference in physical workers, beef-rib tang, wild onion and shepherd's purses muchim, soybean sprout, fish jeorim, fried sweet potatoes were high preference. 4. Preference of Snacks; The preferences for snacks were high in strawberry (clerical:36.3%, physical:34.3%), milk (49.9%, 44.4%), waxy rice Doek (30.7%, 30.2%), coffee (40.1%, 38.9%) by two groups in same order.

The Jindo dog is a Korean natural monument and is recognized by the Fédération Cynologique Internationale. A prominent feature is the diverse coat color within the breed. To analyze the genetic basis of variation in the Jindo coat color, we sequenced the protein-coding regions of the melanocortin 1 receptor gene (MC1R). The MC1R coding sequence was determined from 154 dogs in five breeds (Jindo, Labrador Retriever, English Springer Spaniel, Belgian Malinois, and German Shepherd). To confirm the genetic structure of sampled populations, we tested for Hardy-Weinberg equilibrium (HWE) and computed $F_{st}$ The sample populations did not significantly deviate from HWE. $F_{st}$ was 0.02 between white and fawn Jindo dogs; this was lower than $F_{st}$ between breeds. Six single nucleotide polymorphisms (SNPs) were detected in the MC1R coding region. Among the six SNPs, five were non-synonymous (S90G, T105A, Q159P, M264V, and R306ter) and one was synonymous SNP (Y298Y). From the SNPs, we predicted four haplotypes (H1, H2, H3, and H4) for Jindo MC1R. Jindo dogs had different haplotypes corresponding to different coat colors. H1 was frequently observed in white Jindo dogs with an odds ratio of 5.03 (95% CI: 2.27-11.18, p<0.0001), whereas H2 and H4 were observed only in fawn Jindo dogs. Our findings indicate that SNP haplotype can influence coat color. Knowledge of MC1R haplotypes can help discriminate white and fawn coats in Jindo dogs. We hope this report will trigger more research into the genetics of this traditional Korean dog and will be a reference for dogs of Asian origin. Also, our results will provide a useful genetic marker for Jindo dog breeders who have selected for specific colors.

The present study was aimed to investigate the effect of intraperitoneal bupivacaine instillation on postoperative pain after laparoscopic ovariohysterectomy (LOHE) in dogs. Twelve female German shepherd dogs (17-30 kg) were divided into two groups. The treatment group received 4.4 mg/kg of instilled intraperitoneal bupivacaine diluted to 0.25% with an equivalent volume of saline after pneumoperitoneum, but the control group received 1.76 ml/kg of 0.9% saline. Two blind observers measured the extent of dog's pain and sedation by using dynamic interactive visual analogue scale (DIVAS) preoperatively and 0.5, 1, 2, 4, 6, and 12 h postoperatively. At each designated time, blood cortisol, glucose, and creatine kinase (CK) concentrations were also measured. Based on the repeated-measures ANOVA, there were significant differences in time-dependent postoperative changes in patterns of DIVAS-pain score between two groups. In addition, the treatment group had significantly lower DIVAS-pain scores at 1, 2, 4, and 6 h postoperatively compared to the control group. DIVAS-sedation score and biochemical measures including cortisol, glucose, and CK did not show any significant differences between two groups. No complications associated with bupivacaine administration were observed. Thus, instilled bupivacaine intraperitoneally may be an effective method on relieving behavioral expressions associated with postoperative pain after laparoscopic ovariohysterectomy in dogs.

Related to the situation on the Korean Peninsula, by North Korea's threat of war the tension escalates and serious crisis continues. The purpose of this study is to evaluate the subjective perception which the residents of South Korea feel about North Korea's threat of war through a Q methodological analysis framework. In the result of the study, for the North Korea's threat of war the South Korean's recognition type is analyzed into four type such as 'non-reactive', 'fearreactive', 'psychological anxiety' and 'cynical ignorance type'. First, the No. 1 type 'non-reactive' does not empathize with North Korea's threat of war itself, and second type 'fear-reactive' have uneasy feeling like that 'What would happen as things go' and feel a sense of crisis about the North Korea's threat of war. The third type 'psychological anxiety' is type which feels that due to North Korea's threat of war inter-Korean relations is in the crisis. Finally the fourth type 'cynical ignorance' think that North Korea's threat of war is bluffing and also North Korea is like a shepherd boy. The reason to apply Q-methodology in this study is to make it possible to a more in-depth approach to subjective perception and threat of psychological meaning for the threatening message of study participants.

In continuation of the previous $studies^{2{\sim}3)}$, the folate activity levels in 226 Korean food items were determined by a modified microbiological assay with Lactobacillus casei. There was a large variation in folate activity between the different food groups as well as between each individual food. There was also a wide variation in the biologic availability of folate in foods and the different forms of the folate with different foods in varying amounts. Data showed that almost always, foods cooked and/or processed were lower in folate activity than fresh or raw food and the amount of the loss varied greatly in each food. In calculating dietary intake, total rather than free folate activity levels should he used. In addition, loss of folate activity during cooking and processing of foods should be considered as a major concern for appraising diets and food supplies. Among all assayed food items, including Part $I^{2)}}$ and $I^{3)}$, yeast 2800. ug total per 100g the highest folate level. Soybean, spinach, Shepherd's purse and liter of beef and pork had over 100 ug total per 100 g folate activity. Folate ranging over 50 ug total per 100 g was found in all dried legumes, nuts and seeds assayed, Garland Chrysanthemum, leek, mugwort, wafer cress, asparagus, e99 folk and beef kidney. Wheat, sweet Potatoes,dried fungus, green onion, hotrod pepper, lettuce, radish and some fermented soybeen products had considerably higher folate content ranging around 40 ug total per 100 g. Substantial amounts of folate were not found in many food groups, and among specific groups, in part in starch, sweets, fruits, meat, fish, milk, and cooked and processed foods. Soused fish, oils and fats, beverages, liquor and seasonings, other than fermented soybean products, had almost no folate.

The number of abandoned dogs is increasing with the worsening of the economy and the rising of feed value. It was becoming a serious social problem because of the disease transmission and destruction of natural ecosystems by abandoned dogs been wild animal. In order to solve these problems, companion dogs necessary to secure its own genetic information and to establish the systematic tracking system. Using multiplex-PCR method with 27 microsatellite marker (MS marker) divided 3 set, various alleles occurring to 6 dog breed (Labrador Retriever, German Shepherd, English Springer Spaniel, Belgian Malinois, Jindo Dog, PoongSan Dog) make use of markers to determine allele frequency and heterozygosity. MS marker FH2834 and FH2790 have only two allele and most were found in 13 alleles at FH3381 and FH3399. Average heterozygosity of MS marker is 0.534 and especially, heterozygosity represented the highest value of 0.765 at FH3381. So, it was recognized appropriate allele frequency for individual identification and paternity diagnosis in companion dogs. Using multiplex-PCR method with MS marker, various alleles occurring to dog breed make use of markers to deter mine individual identification and paternity diagnosis, traits associated biomarkers and breed-specific marker for faster, more accurate and ways to reduce the analysis cost. Based on this result, a scientific basis was established to the existing pedigree data by applying genetics additionally. Animal registration system is expected to be conducted nationwide in future. The method expects to very useful this system.

In order to screen natural inhibitor of tyrosinase which catalyzes an enzymatic browning of some foods and in vivo synthesis of melanin, inhibitory effect of 129 edible plants and 15 chemical compounds on the in vivo melanin synthesis by mushroom tyrosinase was analyzed. Among leafy vegetables tested, radish bud, red chicory, Shepherd's purse and small green onion were found to have more than 50% tyrosinase inhibition effect in the descending order. Chinese radish and garlic in root vegetables, and nameko, shiitake and oyster mushroom in mushrooms, and teas showed also more than 50% inhibition effect. Among fruit vegetables tested, red pepper, Chinese quince and avocado were found to have more than 50% tyrosinase inhibition effect, while fruits generally showed low inhibitory effect. Medicinal plants which inhibit tyrosinase more than 50% were mume fructus>cinamomi ramulus>rubi fructus>mori cortex>biotae orientalis folium>puerariae radix, and herbs with more than 50% inhibitory effect were allspice>clove>mustard. In some chemical compounds tested, 4-hexylresorcinol, L-cysteine, glutathione, sodium bisulfite and kojic acid showed powerful inhibition effect on mushroom tyrosinase.

This study attempts to redefine the concept of 'fairness' of Korean public broadcasting and tries to build a new model for evaluating the fairness of Korean public broadcasting. The author insists that the fairness in public broadcasting consists of binary components of the public and rightful reporting, and views that the public reporting represents of neutralness, balance and impartiality while the rightful reporting represents of factuality, multiplicity and the protection of social minorities. The author suggests that two criteria of the public and rightful reporting results in four models of 'shepherd', 'acrobat', 'tribune', and 'trumpeter' in accord with its focus on the public and the rightful reporting. Survey toward the professionals in public broadcasting in academia was conducted and addressed the fact that Korean public broadcasting is close to the trumpeter model with some feature of acrobat.

Procedures for Dietary Fiber(DF) determination were applied to some common vegetables. The samples selected in this study were: Radish(Leaf), Chinese cabbage, Spinach, Shepherd's purse, Red pepper(Leaf), Perilla(Leaf), Soybean(Leaf) and Cabbage. DF was analyzed by the method of detergent fractionation. Values for NDF, ADF, Lignin, Hemicellulose, Cellulose were obtained. NDF for most samples was $12.9{\sim}27.4%$, except Soybean(Leaf) (41.9%), ADP was $7.7{\sim}16.9%$. Lignin was around $1.0{\sim}2.1%$; Red pepper (Leaf) (7.6%), Perillar(Leaf) (5.7%), Soybean(Leaf) (4.2%) were exceptions. $Hemicellulose(NDF{\sim}ADF)$ was about $2.9{\sim}12.0%$, except Soybean(Leaf) (25.0%). $Cellulose(ADF{\sim}Lignin)$ was $6.3{\sim}13.0%$. This paper describes two properties of the fiber of commonly eaten vegetables; Water-Holding Capacity(WHC) and Density. The capacity of the ADP to hold water was estimated. The WHC measurements differed from 6.6g per g of ADP for Red pepper(Leaf) to 10.4g per g of ADP for Radish(Leaf). Radish(Leaf), Soybean(Leaf) had the greatest WHC whereas Red pepper(Leaf), Perillar(Leaf) had the least. Two types of density determinations are shown. Direct (non-packed) values largely correspond with bulk(packed) density.

The objective of this study was to know the herbicidal activity of the essential oil from amyris (Amyris balsamifera). In a seed bioassay experiment, the amyris essential oil inhibited the growth of rapeseed (Brassica napus) by fifty percent at 8.8 ${\mu}g\;g^{-1}$. And in a greenhouse experiment, sorghum, barnyard grass and Indian jointvetch, which was applied in above-ground parts, with the amyris essential oil at 4,000 ${\mu}g\;ml^{-1}$ showed visual injuries of 90, 70, and 70, respectively (0, no damage; 100, total damage). However, soil application of the essential oil did not show such herbicidal injuries. In a field experiment, foliar application of the amyris essential oil at 5% controlled effectively weeds such as barnyardgrass, shepherd's purse, and clover in 24 hours. Our results indicated that the amyris essential oil had herbicidal activity. To understand the composition of the amyris essential oil, the oil was analyzed by gas chromatography-mass spectometry with solid-phase micro-extraction apparatus. There were 15 organic chemicals in the oil and the major constituents were calarene, elemol, ${\gamma}$-eudesmol, curcumene, ${\beta}$-sesquiphellandrene, zingiberene, selina-3,7(11)-diene, 1,3-diisopropenyl-6-methyl-cyclohexene, ${\beta}$-bisabolene, and ${\beta}$-maaliene. Overall results suggest that the amyris essential oil had a herbicidal activity with fast, contact, and non-selective mechanism.
