Grapefruit seed extract powder (GFSEP), which was made with grapefruit seed extract and calcium carbonate, was investigated to retard the fermentation rate. The mixing ratios of GFSEP to salted Chinese cabbage were 0.1, 0.3 and 0.5％. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured during fermentation at 10$^{\circ}C$. pH and reducing sugar content of control and kimchi sample with 0.1％ GFSEP showed decreases until 10 days, and then attained to stabilized levels. Kimchi samples with 0.3％ and 0.5％ GFSEP maintained a higher pH and reducing sugar content, while microbial load was lower than others. Based on the pH and tit ratable acidity, kimchi samples with GFSEP prolong the shelf life about 3～10 days.

In an attempt to test the storage life of late maturing-medium grapes, Sheridan, Tano Red and Muscat Bailey A cultivated widely in Korea, were selected as test samples. These grapes were treated with SO2 gas and packed with polyethylene film, then stored at 0$^{\circ}C$ under 90% RH. Total weight decreased with the storage days and the loss extent of Sheridan was the least. Abnormal grapes increased along with the storage days and occurred rapidly after 90% days. After 135 days, these were produced as the following order. Sheridan < Muscat Bailey A < Tano Red. The external appearances were deteriorated with the storage days. After 135 days, these indices of Sheridan, Muscat Bailey A and Tano Red wen 6.3, 5.0 and 1.7, respectively, showing the most satisfactory result from Sheridn. Water content decreased along with the storage days. The soluble solids content and the proportionality of sugar to acids increased with the storage days, however the titratable acidity decreased. Considering these results, the storage lifes were excellent by the order Sheridan, Muscat Bailey A and Tano Red.

The antimicrobial properties of methanolic extract (PML) from Prunus nune byproducts after liquor manufacturing weremeasured using various putrefactive and food spoilage microorganisms. PML showed remarkable antimicrobial effects against various putrefactive and food spoliage microorganisms when used at 500g/mL. The antimicrobial properties were stable for 30 min at 100C and at pH 3 11. PML seems to be a natural antimicrobial agent with high effectiveness, and shows both thernal and pH stability. In addition, the mode of antimicrobial action suggests that the active components may synergistically perturb microbial membrane functions.

This study attempted to examine the profitability and marketing costs of seed potato under contract farming system of BADC (Bangladesh Agricultural Development Corporation) with the help of primary and secondary data. Total 45 contract farmers were randomly selected. Attempts were made to calculate costs, returns and profitability of seed potato production under contract farming system, and to identify marketing channels of seed potato. The field level data were collected by a farm survey during the months of April 2005 through direct interviews with contract farmers and registered dealers using a structure survey questionnaire. The results showed that the gross return per hectare was Tk. 252,464 for all categories of farms. Cost of seeds, fertilizers, pesticides, irrigation and human labor were critical inputs for profitability of seed potato. Cobb-Douglas production function analysis was used to determine the effects of the key variables to seed potato production under contract farming system. The elasticity of seed potato production was at 0.727 for all categories of farms. The findings exhibited that the summation of elasticity of different inputs for seed potato production was less than one, implying that the production function exhibited decreasing returns to scale. Registered dealers and Upazila Sales Centers were involved in seed potato marketing formed a straightforward marketing channel. The total marketing costs of registered dealers were Tk. 759.49 per ton of seed potato. The net marketing margin of registered dealers was estimated at Tk. 465.51 per ton of seed potato. The selected contract farmers and registered dealers faced a number of problems and some of recommendations were suggested.

The oriental melon poses challenges in terms of long-term storage and distribution. Addressing these issues requires an extension of the storage life through appropriate processing. In this study, pretreated hot-air dried oriental melon slices (steamed and freeze-thawed) were prepared, and their physicochemical and organoleptic properties were examined. The control group (CON) consisted of hot-air dried oriental melon slices without pretreatment, while the steamed group (STG) and freeze-thawed group (FTG) consisted of hot-air dried oriental melon slices pretreated using steaming and freeze-thawing methods, respectively. The moisture contents detected in the CON, STG, and FTG groups ranged from 15.96% to 27.30%, with variations of 7.53 to 8.40 °Brix for the soluble solid contents. The CON group showed the highest Hunter color value for lightness (L^*) and the lowest value for redness (a^*). The texture profile analysis revealed the highest hardness and chewiness in the order of STG > CON > FTG. Considerable differences were observed in springiness and adhesiveness in the FTG group compared to the other groups. The organoleptic evaluation showed that the CON group had the highest sensory scores for overall preference. These findings indicate that the properties of hot-air dried oriental melon slices were influenced by physical pretreatments and that manufacturing these slices without pretreatment is the most effective method in terms of processing simplicity and cost efficiency.

France is known to be making particular efforts to maintain its traditional urban architectural culture by diverse measures including the implementation of urban policies. However, France is facing up to the need to pursue modern urbanization in keeping with the requirements of the current times. Thus, this paper examines with what priority France is attempting to reflect in its current urban policies its determination to retain its urban architectural tradition and to recreate its capital city of Paris as a future European hub city. To that end, the paper first seeks to analyze Paris' policies for urban architecture from diachronic perspectives in a bid to determine Paris' urban architectural culture. Second, the study attempts to examine within the purview of the paradigm of contemporary urban architectural designs how Paris is pursuing the two conflicting purposes of the preservation of tradition and modern urbanization through the Paris Local Urbanization Plan (or Plan Local d'Urbanisme [PLU]). First, the findings indicate that Paris is applying the principle of a sustainable development plan in all fields of environment, economy and society. In terms of environmental sustainability, Paris is trying to improve the life quality of its citizens through the establishment of efficient mass transportation systems and the expansion of its green belt areas. In terms of social sustainability, Paris is implementing policies to ensure social diversity through housing policies. Also, in terms of economic sustainability, Paris is trying to expand employment and bolster its urban functions by conserving commercial activities and developing peripheral urban areas. Second, the findings indicate that Paris' policy of recovering its traditions takes priority over that of creating a sustainable city.

This study investigated laundry behavior. laundry awareness. clothing behavior for environment preservation of university students living at dormitory and relationship among the students' backgrounds. above three aspects. The survey data were collected from the students at Korea National University of Education located in Chung-Buk on November, 2003. The results showed that the laundry awareness of university students living at dormitory was relatively high, but the students' actual laundry behavior was unscientific and according to customs leading to waste of various resources and water pollution. The students' clothing behavior for environment preservation occurred very rarely. Female students and the students had laundry education were superior to laundry awareness and laundry behavior. Therefore, it will be necessary to develop and enforce laundry education program which is not just providing knowledge of laundry but improving power of practical application to real life situation for university students who might be one of family members in immediate future.

The digital archives of E-culture, E-government, E-learning, and E-business have grown by leaps and bounds worldwide during the last several years. While we have invested significant time and effort to create and maintain those archives, we do not have the ability to make digital records generated by the processes all available across generations of information technology, making it accessible with future technology and enabling people to determine whether it is authentic and reliable. This is a very serious problem for which no solutions have been devised yet. This paper discusses practical technologies for digital archives and preservation to succeed, and describes a general framework of the life cycle of information to address this important problem so that we may find reasonable ways to preserve digital records that can be analyzed and evaluated in quantitative measures and incremental manners.

In recent years, there has been an interest to use Moringa oleifera as the natural coagulant due to cost, associated health and environmental concerns of synthetic organic polymers and inorganic chemicals. However, it is known that M. oleifera as the natural coagulant is highly biodegradable and has a very short shelf life. This research was carried out to investigate the effects of storage temperature, packaging methods, and freeze-drying on the preservation of M. oleifera seeds powders. Non freeze-dried M. oleifera was prepared into different packaging namely open container, closed container and vacuum packing, whilst, freeze-dried M. oleifera was stored in closed container and vacuum packing. Each of the packaging was stored at room temperature ($30\;to\;32^{\circ}C$) and refrigerator ($4^{\circ}C$). The turbidity removal efficiencies of stored M. oleifera were examined using jar test at monthly interval for 12 months. The results indicated that non freeze-dried M. oleifera kept in the refrigerator ($4^{\circ}C$) would preserve its coagulation efficiency. In addition, closed container and vacuum packing were found to be more appropriate for the preservation of non freeze-dried M. oleifera, compared to open container. Freeze-dried M. oleifera retained its high coagulation efficiency regardless the storage temperature and packaging method for up to 11 months. Besides, higher increment in zeta potential values for water coagulated with freeze-dried M. oleifera indicated the higher frequency of charge neutralization and better coagulation efficiency of freeze-dried M. oleifera, compared to non freeze-dried seeds. As a coagulant, M. oleifera did not affect the pH of the water after treatment.
