A characteristic of subtropical zones region MK-T2 compares with an gaeryangppong, and the 9-10 schedule the times when a leaf blooms to are fast, and ratio that a branch edge by the colds becomes lean showed 5.7%, and a growth of the new branch which went out delivers 67.2 cm, mulberry loaves of the new branch which went out, and 18.6, a form of a leaf is the 1.10 that length of a leaf grew more a bit than width of a leaf up. Thickness of a leaf is $228.2{\mu}m$, and an area is more similar than gaeryangppong as $225.6cm^2$. in plant taxonomy, the hair whom the style exists short with 0.7 mm, and go to the pistil head inside so as to be rare is distributed, and belong to Dolichostylae Pubescentes. The new branch cutting which executed without remedy processes was independent of a thickness of a case branch, and the form and 100% root was said, and an gaeryangppong compared with the fact that 10% root went out of 15 mm ideal, and was excellent very, and looked, a root went out a root the soil and water, all showed a characteristic to go out at central of a branch bases at 45% ratio. Length was 24.6 mm, and were water rate 78.8%, and mulberry of MK-T2 was carrying together sweetness and acidity to pH 4.7 while, besides, arrival was 19.21 Brix%. A larva period and pupa ratio, cocoon thickness ratio are almost similar to gaeryangppong, or weight of one cocoon, cocoon thickness, 20,002 cocoon quantity shows some results to drop, and be soft of a leaf, and feed value certifications are comparatively top-ranking. As a result of having analyzed amino acid of the 3rd day of 5th silkworm larva which bred to MK-T2, a collation absorbing an gaeryangppong went, and looked, but compared with a collation in case of tests to eat MK-T2, and looked, and the lie collations were not detected a difference at Leu, but MK-T2 tests were detected mutual almost similar amino acid creation. medical efficacy of the 3rd day of 5th silkworm larva ethanol extract which bred to MK-T2 and black results, histologic a case did not appear at HE dyeing about the kidney organization which extracted form the rats which ate a silkworm ethanol extract and dyeing all chemical organization immunity, and one step protein revelation became lower with almost unidentified levels.

The pharmacological efficacy of Protaetia (P.) brevitarsis larvae has been described in the Dongui Bogam. It is believed that the larvae are particularly useful for hepatic disorders. However, natural aversion has made it difficult to consume these larvae as food. Thus, we sought to make an eatable form of the larvae by establishing optimal conditions for larvae preparation. Larvae were selectively bred, sterilized, and a powder of larvae generated by freeze-drying. Afterward, the CellTiter $96^{(R)}$ AQueous Non-Radioactive Cell Proliferation Assay (MTS) with the RAW 264.7 cell line was used to validate the safety of the powder as a food ingredient. We determined that oak sawdust sterilized by water vapor for 5 minutes could be used for larvae feed, and a feeding for 3~5 days followed by a fasting for 3 days were optimal conditions for larvae preparation. In addition, sterilization of larvae at $115^{\circ}C$ and $0.9kgf/cm^3$ (to avoid contamination of pathogenic bacteria and fungi) was successfully applied in the production of edible powder from P. brevitarsis. The optimized processes established in our experiments can be used in the industrial production of P. brevitarsis as a food ingredient.

In trying to predict the effect of genetics on the broiler in the year 2000, this is a relatively short period of time as far as broiler genetics in concerned. Modern broiler genetics started around 1945 and tremendous gains when made in past 35 years. Futher improvements on broiler will depend on the evolution and revolution: 1. Evolution: (1) Growth rate has been made 4-5% per year. (2) Feed conversion has improved approximately 1% per year. (3) Abdominal fat is becoming a major complaint in broiler. (4) Because of the changing life-style, broiler meat sales in the future will be more and more in cut-up form. (5) Breeding for stress resistance and selection for docile temperament can be important in order to funker improve fled efficiency. (6) In female parent stock, reproduction characteristics are in many can negatively correlated with the desired broiler traits. (7) Egg production and hatchability in moot commercial parent nod m at a fairly high level. (8) In male parent stock, the heavier and mon super-meat-type male lines are desired to Product better broilers. 2. Revolution: Trying to forecast revolutionary change in broiler genetics is highly speculative, as sudden change are aften unpredictable. (1) Species hybridization, such as a turkey-chicken cross (2) Biochemical tools, such as blood typing. (3) Mutation breeding by radiation or chemical mutagentia. (4) Broiler breeding would be to change the phenotypic appearance by single gene, such as naked, wingless. (5) Changes in production techniques. such as growing in cage or growing in filtered air positive pressure houses.

A goby, Synechogobius hasta (Temminck et Schlegel) was studied to investigate the food consumed and the biological change of the food organisms, and the fish were sampled from the closed tributary and the lower Part of the Naktong River, near Pusan, during the period from November of 1967 to December of 1968. The fish were sampled from four stations (Fig. 1), the total number of fish being 1,295 and they were grouped and analysed monthly. The content of the alimentary canal was analysed in three categories according to modified Nilsson's method (Dahl 1962) with a slight alteration: 1) The number of each item of stomach contents was counted and the percentage of each item in proportion to the total number of food organisms is indicated by the letter 'N' representing numerical percentage in Table 2. 2) The percentage of fish which contained any items of food organisms in proportion to the total number of fish caught in a given season is indicated by the letter 'O' representing frequency of occurrence. 3) Dominant groups of food items were selected and the percentage of the number of each dominant item in proportion to the number of the food organisms belonging to the dominant groups is indicated by the letter 'D' representing dominance. All food organisms were classified in 50 food item categories and then they were grouped in 13 main groups (Fig. 2-1), and they were further divided into 1) obligatory bottom animals, 2) organic drifts and 3) actively swimming forms; according to the conditions of the animal communities within the habitat. Since the majority of its food was composed of the obligatory bottom animals ($94.6\%$), the fish appeard to be a typical bottom feeder. And the dominant food organisms of the fish is generally determined by the local composition of the benthic fauna within the fish habitat. And their seasonal rhythm occurs among the food organisms in the stomach by the biological interaction. Locality variation in the population of the same food organism occurs due to the difference of food organisms in the habitat of the fish at Seonam and Garak, and at Seongsan and Hadan the condition of the niche for the fish in the both regions seems to be the same since the composition and the seasonal variation of the organisms were the same. The results may be summarized as follows: 1) The goby mainly feed on the animals of bottom fauna, and the food organisms are deter-mined by the food compositions within the habitat. 2) Seasonal variation of the stomach content shows the seasonal rhythm due to the biological variation of the population and their interaction. 3) The goby shows no preference on specific food, and the food is composed of a variety of animals. 4) Major food items of the goby are Polychaeta, Palaemon modestus, Isopoda, Gammaridea, Insecta (nymphs and larvae), Ilyoplax deschampsi, and Paratye compressa. 5) Logitudinal succession oil the population of the food organisms is apparently recognized within the community of Seongsan, Garak and Seonam. 6) The goby begins to descend toward the estuary and sea around April when the water temperature reaches $20^{\circ}C$, and they begin to return to river waters in September.

This paper analyzes the cases where the hotels have increased their services and enhanced their work process through IT solutions to cope with computerization globalization. Also the cases have been studies where national hotels use the CRM solution internally to respond effectively to customers requests, increase customer analysis, and build marketing strategies. In particular, this study discusses the introduction of the CRM solutions and CRM sales business and marketing services using a process for utilizing the presumed, CRM by introducing effective DEA(Data Envelopment Analysis). First, the comparison has done regarding the relative efficiency of L Company with the CCR model, then compared L Company's restaurants and facilities' effectiveness through BCC model. L Company reached a conclusion that it is important to precisely create and manage sales data which are the preliminary data for CRM, and for that reason it made it possible to save sales data generated by POS system on each sales performance database. In order to do that, it newly established Oracle POS system and LORIS POS system concerned with restaurants for food and beverage as well as rooms, and made it possible to stably generate and manage sales data and manage. Moreover, it set up a composite database to control comprehensively the results of work processes during a specific period by collecting customer registration information and made it possible to systematically control the information on sales performances. By establishing a system which unifies database and managing it comprehensively, impeccability of data has been greatly enhanced and a problem which generated asymmetric data could be thoroughly solved. Using data accumulated on the comprehensive database, sales data can be analyzed, categorized, classified through data mining engine imbedded in Polaris CRM and the results can be organized on data mart to provide them in the form of CRM application data. By transforming original sales data into forms which are easy to handle and saving them on data mart separately, it enabled acquiring well-organized data with ease when engaging in various marketing operations, holding a morning meeting and working on decision-making. By using summarized data at data mart, it was possible to process marketing operations such as telemarketing, direct mailing, internet marketing service and service product developments for perceived customers; moreover, information on customer perceptions which is one of CRM's end-products could feed back into the comprehensive database. This research was undertaken to find out how effectively CRM has been employed by comparing and analyzing the management performance of each enterprise site and store after introducing CRM to Hotel enterprises using DEA technique. According to the research results, efficiency evaluation for each site was calculated through input and output factors to find out comparative CRM system usage efficiency of L's Company four sites; moreover, with regard to stores, the sizes of workforce and budget application show a huge difference and so does the each store efficiency. Furthermore, by using the DEA technique, it could assess which sites have comparatively high efficiency and which don't by comparing and evaluating hotel enterprises IT project outcomes such as CRM introduction using the CCR model for each site of the related enterprises. By using the BCC model, it could comparatively evaluate the outcome of CRM usage at each store of A site, which is representative of L Company, and as a result, it could figure out which stores maintain high efficiency in using CRM and which don't. It analyzed the cases of CRM introduction at L Company, which is a hotel enterprise, and precisely evaluated them through DEA. L Company analyzed the customer analysis system by introducing CRM and achieved to provide customers identified through client analysis data with one to one tailored services. Moreover, it could come up with a plan to differentiate the service for customers who revisit by assessing customer discernment rate. As tasks to be solved in the future, it is required to do research on the process analysis which can lead to a specific outcome such as increased sales volumes by carrying on test marketing, target marketing using CRM. Furthermore, it is also necessary to do research on efficiency evaluation in accordance with linkages between other IT solutions such as ERP and CRM system.

Earthworm casting was the natural fertilizer that contained high concentrations of nutrients such as nitrogen, phosphate and potassium and of over $10^8$ CFU/ml of microorganisms. Greater than 80% of feed was excreted through the fermentation by the intestinal enzyme, after worm had eaten feeds such as fallen leaves and rotten roots under the ground. Also, the soil structure of casting was known to be very efficient in the aspects of the porosity, the water permeability, and deodorizing activities. In this research, the biofilter packed with a biomedia made of casting and waste polyurethane foam, a binder, which helped to improve the durability and perpetuity of casting, was investigated to degrade malodorous hydrogen sulfide gas. The biomedia had no need of extra supply of nutrients and of microbial inoculations. On the beginning of the operations, it showed 100% removal of hydrogen sulfide gas without lag phase. At SV of 50 $h^{-1}$, hydrogen sulfide gas from the outlet of the biofilter was not detected, when inlet concentration increased to 450 ppmv. After that, removal efficiency decreased as increasing inlet hydrogen sulfide concentration. Hydrogen sulfide removal was maintained at almost 93% until inlet concentration was increased up to 950 ppmv, at which the elimination capacity of $H_2S$ was 61.2 g $S{\cdot}m^{-3}{\cdot}h^{-1}$. Maximum elimination capacity guaranteing 90% removal was 61.2, 65.9, 84.7, 89.4 g $S{\cdot}m^{-3}{\cdot}h^{-1}$ at SV ranging from 50 $h^{-1}$ to 300 $h^{-1}$, but was 59.3 g $S{\cdot}m^{-3}{\cdot}h^{-1}$ at SV of 400 $h^{-1}$. The results calculated from Michaelis-Menten equation revealed that $V_m$ increased from 66.04, 88.96, 117.35, 224.15, to 227.54 g $S{\cdot}m^{-3}{\cdot}h^{-1}$ with increasing space velocity in the range of 50 $h^{-1}$ to 400 $h^{-1}$. However, saturation constant$(K_s)$ decreased from 79.97 ppmv to 64.95 and 65.37 ppmv, and then increased to 127.72 and 157.43 ppmv.

This study was undertaken to determine the effects of diet supplementation with complex probiotics (CPB), on growth performance, nutrient digestibility, blood metabolites, noxious gas, and fecal microflora in weaning pigs. On the basis of body weight, a total of 234 weaned pigs (Landrace×Yorkshire×Duroc, 6.14±0.78kg) were randomly allotted to 3 treatments and 6 replicates (13 pigs per pen). The experimental diets were fed in a meal form for 28 days (days 0-14, PhaseI, and days 15-28, PhaseII). The dietary treatment groups were as follows: T1 (basal diet), T2 (T1+0.13% CPB) and T3 (T1+0.25% CPB). The CPB supplement contained Bacillus subtilis 1.0×10⁶ CFU/g, Enterococcus faecium 1.0×10⁶ CFU/g, Saccharomyces cerevisiae 1.0×10⁶ CFU/g, Bacillus licheniformis 3.0×10⁸ CFU/g, and Bacillus polyfermenticus 3.0×10⁸ CFU/g. Pigs fed the T3 diet showed an increase (p<0.05) in the overall average daily gain and average daily feed intake, increased (p<0.05) crude protein digestibility in PhaseI, and greater (p<0.05) dry matter and gross energy digestibility in PhaseII. Supplementation of CPB had no effect on the blood profile. Furthermore, pigs fed the T3 diet had lower (p<0.05) NH₃ emission and overall count of fecal Clostridium spp. In conclusion, we believe that CPB supplementation has a beneficial effect on growth performance, nutrient digestibility, noxious gas, and fecal microflora in weaning pigs.

This study is carrying out a before and after experiment design for the non-equal comparative group to identify the effects of the breast self-examination education on breast self-examination participant education compliance and health promotion in women. The subject of this study was 58 women residing in Chungju. Their age ranged from 20 to 40. These women were not pregnant or did not breast feed, as well as they did not have any breast disease, at the time of survey. They were available for the response to the questionnaires, and understood the purpose of this study. They also agreed to participate in the study, and responded to the 3rd time questionnaires to the end. Thus, brochures and lectures were provided side by side to a group of 19 of those women, and only brochures were provided to another group of 39 of those women. With regard to education, a brochure and a program using a breast model were applied. Then, the frequency of the breast self examination compliance, breast self examination capability and the relations between the breast self examination and activities to promote health were measured, before the education, after 4 weeks of education and after 12 weeks of education. Before education and after 4 weeks of education. I collected the questionnaires myself visiting them, and after 12 weeks of education, the questionnaires were collected by mail. In relation to the study tool, the breast self examination activity was measured by two measuring tools: breast self examination activity frequency and breast self examination compliance capability. As for the frequency, the number of self examination for the period of 3 months, before the questionnaire survey, was measured in the form of self report. In relation to the tool to measure the breast self examination capability, the BSEPRI tool, which was developed by Wood in 1994, was used. Here, as the score was higher, the capability was indicated to be higher. The translated and revised version of Health Promoting Lifestyle Profile II (Walker, Sechrist & Pender. 2002) was used as a tool for health promotion. As the measured score was higher, the health promoting activity was indicated to be higher. The results of this study were as follows: 1. As a result of checking the breast self examination compliance frequency between the experiment group that received the breast self examination participant education and the comparative group that did not receive the education, there was a significant difference in interaction between groups by time, as time passed by. 2. As a result of checking the breast self examination compliance capability between the experiment group and the comparative group, there was a significant difference in interaction between groups by time, as time passed by. 3. As a result of carrying out a repetitive measurement analysis, between the experiment group that received the breast self examination education and the comparative group that did not receive the education, which was carried out to validate the hypothesis that the former would have higher health promoting activities than the latter, there was no significant difference after the breast self examination education was conducted.

All diets were based on feeds of fattening period pigs(LY x D, ca. 90 kg) with six treatments, which were the control, containing 5% beef tallow(C), 3% beef tallows and 2% perilla seeds oil(T1), 250 ppm vit. E(${\alpha}$-tocopheryl acetate) in T1(T2), 3% beef tallow and 2% squid viscera oil(T3), 250 ppm vit. E in T3(T4), and 3% beef tallow and 2% CLA(T5), respectively. Produced porks and their carcass characteristics were as follows. The daily gain of pigs was higher in T2 and 73 than any other treatments(p<0.05). Its T2 and T3 was 3.71 and 3.80 respectively, however, there was no significance in feed intake. The highest back fat thickness was shown in control group on market weight, while there was no significant difference on their initial weight. Loin-eye muscle area did not show any significant difference on initial weight and on market weight, however, its T5 was about twice as large as T2's. Content of triglyceride in blood was high in control group as compared to others; especially, the values for T3, T4 and T5 were significantly low(p <0.05). There was no significant difference in total cholesterol contents, and the ratio of HDL cholesterol/total cholesterol was higher in vit. E treated samples than untreated sample. Atherogenic index was high in sample with T3 and low in sample with T2. The perilla seed oil, squid fish oil, and vit. E decreased atherogenic index. Dressing percentage, back fat thickness, and grade did not show any significant difference(p >0.05); however, T2, C and T3, T1 and T5 showed 4.67, 4.29, 4.00 respectively, in grades.

This study was designed to standardize recipe and analyze the nutrients of Aguyjjim (stewed angler), a kind of native local foods in Busan. The results of this study are summarized as follows. The form of angler and its way to catch for a bait were recorded in Jasanobo, but the recipe was not written. While angler was used as manure or feed once, it was boomed for Aguyjjim since 80's, accredited as high-quality fish and protein-rich food. The standard recipe of Aguyjjim was prepared (through 3 times experimental cooking), being based on the recipe of cookbooks and restaurants. Then standard recipe was subjected to sensory evaluation. All sensory properties (appearance, smell, texture etc.) of Aguyiiim were evaluated as “like slight S, moderately”in hedonic scale. Energy per 100 g of the Aguyjjim was 89 kcal. It contained protein (10.7 g), fat (1.3 g), fiber (2.6 g), Ca (45 mg), Fe (1.3 mg) and so on. Amino acid is mainly comprised glutamic acid and aspartic acid. Free amino acid contents such as asparagine, glutamic acid, taurine were high. Fatty acid primarily consisted of unsaturated fatty acid like oleic acid, linoleic acid. Traditional foods are based on that of local foods. However, there has been little study looking into the recipes and nutritional value of local foods. Aiming at development of traditional food, the present study offered the standard cuisine of Aguyiiim that is a kind of local foods in Busan. In addition, it presented the composition of nutrients, amino acids and fatty acids. This data would be helpful for houses, restaurants and food service facilities to revive the local foods.
