  • The principal objective of was to assess the effects of herb extracts on the antioxidant activity and quality characteristics of Maejakgwa. The total phenolic and flavonoid contents were found to be the highest by a significant degree in the rosemary, lavender, thyme, lemon balm and olive samples, in order. With regard to electron donating ability, increasing concentrations of added herbs resulted in a more significant rise in the DPPH radical scavenging effect in a range of concentrations of between $100{\sim}1000{\mu}g/m{\ell}$. In particular, the rosemary, lavender, and thyme samples were shown to be lower in antioxidant activity than ascorbic acid, but higher than a-tocopherol, thus the antioxidant activities detected in the rosemary, lavender, and thyme samples were considered to be excellent. With regard to reducing ability, increases in the concentration of added herb extract resulted in significant growth. However, the anti-oxidative activity detected in the rosemary extract was indicated to be superior even to that of $\alpha$-tocopherol when added to concentrations of $500{\sim}1,000{\mu}g/m{\ell}$. In our assessment of external appearance, color, flavor, texture, and overall quality, the highest preference was seen in the control group and in the group with 2% added rosemary extract. The lowest score was earned in the group with a 5% addition of rosemary. The functional ingredients and antioxidant activities of the samples were excellent. Our results appear to indicate that rosemary has some value as a natural antioxidant that can prevent oxidation in food.

  • The purpose of this study was to research the effects of socio-demographic factors and values in each group on satisfaction with life by categorizing the activity types of the elderly into volunteer work and economic activities. The subjects of this study were 60 years an old higher. The questionnaires were categorized depending on activity types and collected. The voluntary work group consisted of 201 people (76 males, 36.8% and 125 females, 62.2%), The economic activity group consisted of 219 people (127 males, 58.0% and 92 females, 42.0%). The SPSS 14.0 Windows program was used to analyze data. Frequency, average, standard deviation, factor analysis, Pearson correlation coefficient, t-test, One-Way ANOVA analysis, and hierarchical multiple linear regression were analyzed. The major findings of this study indicate that the elderly in the voluntary work group have a high collectivism value, higher income earned by performing economic activities, and good cognitive health affected by a high satisfaction with life. From these research results, it was proved that a collectivism value is a common factor that affects satisfaction with life in both of the economic activity group. Those who were older had a traditional collectivism value. The voluntary work group showed a stronger collectivism value and higher satisfaction with life than the economic activity group. Thus, the diverse types of voluntary work should be developed and a systematic system should be established as methods for improving quality of life and satisfaction.

  • The provision of information on the profitability and efficiency during the transition from growing rice to substitute crops is an essential task for the proliferation and settlement of the production adjustment system. First, the profitability of the soybean + barley cropping system was analyzed. The average income of the farms with the soybean + barley cropping system surveyed was 868,000 Won, with an income proportion of 55.1%. With earned income that is approximately 1.7 times higher than that of growing only rice, it is determined to be more profitable. Then, the efficiency of the farms was analyzed through DEA analysis. The efficiencies of the farms were found to include the CCR model (0.927815) and the BCC model (0.97544). It was also found that there are 10 CCR and 14 BCC results with an efficiency value of 1. With an efficiency value of more than 0.9 on average, it can be deemed as efficient management in general. In addition, by presenting a proposal for the improvement of inefficient farms, the target value was provided in order for inefficient farms to become efficient farms.

  • This study is aimed to analysis the fishery consciousness of the fishermen in Kyungbuk province. an issue for the study may be used on activating device of fisheries high school. So, the data were collected from a fishermen living at the city of Pohang in Kyungbuk province. The treatment of materials are classified by age, level of a school career and by working career. This research evaluated percentage to the frequency of responses to each question and carried out $\chi^2$. The statistically signigicant level account for p<.05 and made use of SPSS 10.0. The conclusion of study were as follows; First, fishermen have little understanding for fishery consciousness, therefore there was needed public activities and life long education. Second, in order to solve the difficulties of fisheries villages, governmental financial support have to be presented, It is showed that economically, culturally, and financially, govermental policy should be devised for the purpose of emerging from backwardness of fisheries villages. Third, large portions of economic value should be allocated to fisheries villages by improving fisheries structure. Actually, lower incomes haves have burdened fisheries villagers with more debts. More years of being engaged in fisheries have resulted in more debts. People in fisheries villages regarded incomes as the most important among factors in their selecting fisheries as a job. If they earned more money in fisheries village than in metropolises, people on fisheries villages would choose the fisheries an their jobs. Naturally, there will prove to be an increase of number of persons engaged in fisheries. Also, thinking of fisheries as dangerous and heavy should be corrected into the new image by improving work environments and mechanization.

  • For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

  • The Office of Korean National Railroads announced a design competition for Kwangyang Station and sought design proposals in October of 2002. The authors collaborated on a landscape design for Kwangyang Station and earned first prize in the competition. The Office decided to construct outdoor public spaces of Kwangyang Station for railroad users, visitors and staff, and local residents. The landscape design covers the following: site inventory and analysis; integration of design program and site analysis; evaluation of design concept; selecting a winning design alternative; schematic design including circulation form and spatial form; and design development including subarea design. In the design process, the authors focused on the integration and interpretation of site conditions as related to the Kwangyang Station building. They also collectively analyzed and considered the physical development of the outdoor spaces of Kwangyang Station. The following are some of the major areas in the design of the outdoor spaces of Kwangyang Station: 1) a plaza for waiting, 2) an entry area for passengers, 3) a train cafeteria, 4) a cultural plaza, 5) an image wall, and 6) a symbolic pond. The plaza for waiting is created as a place for users to wait and rest. The entry area for passengers provides an area for pedestrians approaching, passing and strolling. The train cafeteria features trains, lawns, grasses and trees. The cultural plaza is a main area representing the regional characteristics of Kwangyang. This plaza also provides an area for various public events. The image wall is meant to be an exhibition space for displaying the advancements of Korean National Railroads in sculptural image forms. The symbolic pond consists of an area with symbolic water features and several sculptures with artistic value. In the authors' design, the outdoor spaces of Kwangyang station are created as a new type of public realm with function, regional quality, original identity, cultural context, symbolic meaning and images, and beauty. The designed spaces would be one of the most representative places of interest and attraction in Kwangyang.

  • Recently, in Korea, a few construction companies have been tried to develop a management system, which is able to integrate schedule and cost. In spite of these attempts, however, advanced management techniques can be hardly applied under the BoQ based management system. In order to improve these problems, many studies have been peformed, but yet could not overcome practical limitations. Besides, the application of historical data is below the level since it is so difficult to accumulate and feed-back historical data under the unique character of construction industry. Consequently, lots of time and effort have being wasted to establish control criteria. The newly generated Information is not systematically managed as well. Therefore, this study suggests Integrated Construction Management System complemented the existing practical problems.
