This study analyzed and compared characteristic of vegetation structure in Bonghwa mountain, the base Mt. outside urban area, and Hakseoung neighborhood park, Ilsan neighborhood park and Musil neighborhood park, disconnected residual Mt. inside urban area of Wonju. Regarding vegetation of urban forest in Wonju, Quercus mongolica forest and Robinia pseudo-acacia forest were widely distributed in the base Mt. outside urban area. Quercus acutissima forest and Robinia pseudo-acacia forest were widely distributed in the disconnected residual Mt. inside urban area. Forests in both areas were managed as part of forest management campaign. Analysis on importance value of a community classified by DCA and DBH class categorized communities into three groups according to the expected ecological succession. Community B was the one to be maintained as Pinus densiflora community. Community A, D and d were expected to be maintained as Quercus spp. Community. Community C, E, F, e, f and g were classified as exotic plant community. Ecological succession was suspended in both base Mt. outside urban area and disconnected residual Mt. inside urban area. However, importance value of Quercus spp. which appeared in the understory layer and shrub layer and their DBH class showed that the potential for ecological succession of exotic plant community was higher in base Mt. outside urban area than disconnected residual Mt. inside urban area. According to the analysis on number of species and individuals and species diversity, understory and shrub layer were reduced due to Forest Management campaign and plant species which appear at an earlier stage of succession varied as time went by since the campaign began. Species diversity comparison between natural and artificial forest showed no clear difference in both base Mt. outside urban area and disconnected residual Mt. inside urban area due to man-made disruption such as thinning and brush cutting. Six communities in base Mt. outside urban area had 17.76~52.22% of similarity index. Four communities in disconnected residual Mt. inside urban area showed 13.34~37.01% of similarity index, which was lower than base Mt. outside urban area. Among naturalized plants, Tupatorium rugosum and Phytolacca americana appeared more in disconnected residual Mt. inside urban area.

Family Restaurant is a service business of a kind. The role of service operator is to improve a sales of service goods through maximizing the service value with customer satisfaction at the moment of MOT(moment of truth). Family Restaurant come to the great growth on the face of it. In future, it will place emphasis more and more on not hardware but software including service quality. The purpose of this study, therefore, is to research the effect on service quality of the job satisfaction of Family Restaurant's service staff. Data was collected from the employee who are working at Family Restaurant located in Taegu. The empirical research has been done over 50days from 1April, 2004 to 20May, 2004. In conclusion of empirical analysis, 4 hypotheses were significant among 7 hypotheses suggested in this study. The research showed as follows : First, the organic trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed positive influence on job satisfaction. Second, the personal trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed positive influence on service quality. Third, the official trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed negative influence on job satisfaction. Fourth, the organic trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed positive influence on service quality. Fifth, the personal trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed negative influence on service quality. Sixth, the organic trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed negative influence on service quality. Seventh, the job satisfaction of Family Restaurant service staff showed positive influence on service quality. Besides, the critical points of this study are as follows; First, we designated the subject of research to the employee of Family Restaurant only. Second, multi-situations(time, holiday) which can happen as service was offered, wasn't concerned. Third, as service quality was estimated by general service quality, the research in future should subdivide service quality more. I, finally, applied the pervious researches on job satisfaction and service quality in the employee of Family Restaurant. To extend more this research model in future, the variables like customer satisfaction should be added.
The Korea Food and Drug Administration (KFDA) revised the Health Functional Food Act in 2008 and extended the form of health functional foods to general food types. Therefore, this study was performed to investigate consumers' perceptions of the expanded form of health functional food and to predict consumption patterns. For this study, 1,006 male and female adults aged 19 years and older were selected nationwide by multi-stage stratified random sampling and were surveyed in 1:1 interviews. The questionnaire survey was conducted by Korea Gallup. The subjects consisted of 497 (49.4%) males and 509 (50.6%) females. About 57.9% of the subjects recognized the KFDA's permission procedures for health functional foods. Regarding the health functional foods that the subjects had consumed, red ginseng products were the highest (45.3%), followed by nutritional supplements (34.9%), ginseng products (27.9%), lactobacillus-containing products (21.0%), aloe products (20.3%), and Japanese apricot extract products (18.4%). Opinions on expanding the form of health functional foods to general food types scored 4.7 points on a 7-point scale, showing positive responses. In terms of the effects of medicine-type health functional foods versus generic health functional foods, the highest response was 'same effects if the same ingredients are contained' at a rate of 34.7%. For intake frequency by food type, the response of 'daily consistent intake' was 31.7% for capsules, tablets, and pills, and 21.7% for extracts. For general food types, 'daily consistent intake' was 44.5% for rice and 22.8% for beverages, which were higher rates than those for medicine types. From the above results, consumers had positive opinions of the expansion of health functional foods to generic forms but are not expected to maintain accurate intake frequencies or amounts. Thus, continuous promotion and education are needed for proper intake of generic health functional foods.

In the present society, our current technology associated with bakery industry has been improved as much as technical development can get abreast of the Western one where the bread has originated and has been awarded and ranked in the highest level of many bakery or pastry competitions. In these trends, many people are running for high value added business such as bakery industry and bakery $caf{\acute{e}}$, etc. with big interest. However, high labor cost of technician and difficulties in human resource management become obstruction factors in the growth of the bakery industries. Therefore, in this paper, the designed system for both dividing and rounding dough quickly and exactly at the same time was studied. The main function of this system is to divide the original dough into 3 tracks and then, to place 4 doughs in the inner track, 12 doughs in the mid track, 20 doughs in the outer track, totally 36 doughs in a routine. It takes much energy because 36 doughs can be completed in a routine. Therefore, this system uses hydraulic pressure and a 0.75Kw induction motor is used for dough rounding. This system can make primarily fermented dough into 36 divided doughs very quickly and exactly on a guide panel at the desired weight by dividing it within 1-9 seconds and by rounding each within 1-9 seconds. This system is very effective in bakery industry to minimize labor cost and it is expected to supply more hygienic products to the customers.
The purpose of this study was to monitor and compare the contamination levels of heterotrophic bacteria and pathogenic bacteria (total coliforms, Escherichia coli O157:H7, Salmonella spp., Vibrio parachaemolyticus, Staphylococcus aureus and Bacillus cereus). The samples collected at fish farms located in the Jeju-island were investigated from March to August in 2006. The contamination levels of S. aureus, B. cereus and Salmonella spp. ranged $0-3.3{\times}10^2 CFU/ml,\;0-2.2{\times}10^2 CFU/ml\;and\;0-5.1{\times}10^1CFU/ml$, respectively, and 85% of moist pellet feeds were contaminated with S. aureus, B. cereus and total coliforms. But total coliforms and E. coli O157:H7 were not detected in oliver flounder (Paralichthys olivaceus). For the production of safe oliver flounder (Paralichthys olivaceus), education of sanitation for employees, control of fish feed, and continuous monitoring for microorganism will be required.
The purpose of this study was to investigate the effects of demographic characteristics such as gender, marital status, age, educational level, job and monthly income on the preferred menu classified by type of food, food material, cooking method, taste and food temperature. A survey was performed from the 5th to 10th of January, 2013 among consumers in such places as coffee shops and subway stations located in Daegu and Gyeongbuk region, and finally 307 data sets were used for analysis. The results of analysis showed that the strongest effects of demographic characteristics were observed in preferred menu classified by type of food(i.e. Korean, Western, Chinese, Japanese, buffet, herbal and instant foods), and the differences by marital status, age, educational level, job were statistically significant. In particular, the married consumers tended to prefer Korean and herbal foods, while the unmarried ones preferred western, Chinese, buffet and instant food. Moreover, the younger ones tended to prefer western, Chinese, buffet and instant foods, while the older ones preferred to eat Korean food. The younger unmarried ones liked beef and pork dishes, while the married ones over their forties tended to prefer vegetable dishes. The consumers less than or equal to their thirties tended to prefer roasted and fried foods compared to ones over their thirties.

Scale insects heavily damaged many agricultural crops and trees in urban and forest areas. This study was conducted to carry out alternative control methods for environmentally friendly control of scale insects. Hot water extract of Quisquali indica produced high mortality against the black pine bast scale, Matsucoccus thunbergianae in previously experiment. Methanol extract obtained from fruit of Q. indica was successively fractionated using hexane, chloroform, ethyl acetate, buthanol and water which were examined by exposing for their insecticidal activity against four Cocoidea species (Eriococcus lagerstroemiae, Ceroplastes japonicus, Crisicoccus pini and Planococcus citri) in laboratory. Hexane fraction gave the highest insecticidal activity against scale insect pest. GC-mass analysis confirmed that the main compounds of Q. indica were alpha-pinene, methyl palmitate, eugenol, methyl myristate, phthalic acid mono(2-ethylhexyl)ester and palmitic acid. Among those compounds, ${\alpha}$-pinene was included 10 hexane subfractions. $LC_{50}$ of ${\alpha}$-pinene was 0.0114 ppm against 2nd instar of E. lagerstroemiae. These results suggest that Q. indica extracts might be used as an alternative control agent of scale insects.

This study intends to find efficient support methods for small and medium-sized businesses (SMBs) especially in the increasingly important mobile sector. We investigated regarding perceptions of mobile sector-specific support programs and their current state of usage, and perceptions of the new mobile market and the present conditions of each stage of production based on analysis of a survey that included 204 respondents in each SMB to achieve this goal. Concretely, detections through this research were the reasons for non-selection of support businesses, the future prospective mobile business area, the company's own first-preference item and the reason for the preference, plus new mobile areas of willingness to apply the company's own product and its own first-preference item, and the reason for the preference. In addition, we found out covering costs and revenue size of the maximum-revenue product for each stage (from the first to the fourth stage), the kind of a product's execution method connected to the product (e.g. self-production, outsourcing to another company to produce a product), and the execution method for pre-products. We can suggest a policy regarding efficient support alternatives for SMBs related to the mobile sector thanks to these findings.

Geoturism has been discussed from multiple perspectives in geomorphology and geology as well as tourism domain since 2000. As of May 2013, 172 academic papers and reports on Geoturism have been published in domestic journals. Themes of these researches can be categorized into 6 topics: resource development (i.e. natural resource development, cultural resource development, development of geopark), conservation and management, geoturist, local resident participation and public relations marketing, political approaches. Resource development among those topics has been treated the most: development and utilization of important geomorphological and geological landscape resources, storytelling development about cultual resources, contents development for geopark. On the whole, it is significant that geotourism is actively discussed in geography domain such as geomorphology rather than in geology domain. Up to date, those topics have also been treated only in certain academic areas. In the future researches, efforts for the balance among those topics and creating new themes from various research areas is necessary. Moreover, community networking among locals-municipalities-academia is also necessary to increase local participants.

The purpose of this study is to improve the quality of white pan bread by adding polymannuronic acid, an excellent rheological properties material which has the high blood control function in seaweeds, to flour. To investigate the rheological properties appropriate to the making of white pan bread, amylograph, farinograph, extensography were done adding polymannuronic acid(0%, 1%, 3%, and 5%) to flour. The gelatinization condition between flour and compositic flour, amylogram was done. The result was that the gelatinization temperature in flour(100%) was $61.0^{\circ}C$, as polymannuronic acid rate was increased by 1%, 3%, 5%, thetemperature was all the same, $63.5^{\circ}C$. The maximum viscocity temperature of flour(100%) was $92.0^{\circ}C$. that of flour added polymannuronic acid (1%) $92.5^{\circ}C$, those of flour added polymannuronic acid (3%, 5%) unchangeable. $\alpha$ -amylase activity degree, maximum viscocity was that flour(100% was 525 BU, flour added polymannuronic acid (1%) 498 B.U, flour added polymannuronic acid (3%) 385B.U, flour added polymannuronic acid (5%) 360 B.U, highly decreased. Farinograph was done, as the additional quantity of polymannuronic acid increase(1%, 3%, 5%), water absorption rate increase much more thin the control. As the additional quantity of polymannuronic acid is added from 1% to 3%, development time of dough was increase, but one added 5% was decreased. In case of extensograph was done, resistance of dough increased but extensibility is decreased, so R/E value increased.
