This study was carried out to investigate antioxidative properties of various extracts and antibrowning effects of extracts in apple slices were investigated by ΔE value and PPO relative activity. Apples were cut into 1.5 ㎝ thickness and they were dipped in 1% extract solutions(OW: water extracts of onion, OE: 80% EtOH extracts of onion, AW: water extracts of apple, AE: 80% EtOH extracts of apple, MW: water extracts of mandarin orange peel, ME: 80% EtOH extracts of mandarin orange peel) for 1 min. OW showed higher than the other treatments for total phenolic contents(94.35 ㎎/g), PPO inhibition(74.00%). And the highest DPPH free radical scavenging activity(40.27%) measured in ME. ΔE value of apple slices dipped in MW was 2.37 whereas ΔE value of apple slices dipped in AW was 12.12. These results suggest that onion and mandarin orange peel extracts should be a potential source for controlling browning during storage of apple slices.

The aim of this study is to make an active provision against the change of the modern society, regarding the consumption propensity and to establish a foundation for house planning and design through the analysis and materialization of the concrete patterns of consumption. This study consists of two stages ; the first stage deals with the analysis of the housing environment and its lifestyles, the second stage analyzes the characteristics of housing patterns of the aged, apart from the first stage. This study analyzes the characteristics of housing life and ,especially regarding the aged. It summarizes as follows ; Firstly, the Koreans' housing type hierarchically includes owning, leasing, and monthly renting- based on the family income. The increase of income alone makes it difficult for lower income class people to own their houses. Therefore, it is necessary to give them a financial assistance. Secondly, to increase the number of families who have their own houses, the housing financial loan system should be changed. Thirdly, it would be more efficient to stabilize the policy of rent and low the rent to ease overcrowded housing. Lastly, it is required to improve the quality of housing life for the aged, including the size and type of housing.

A 66-year-old man visited author's institute complaining of the swelling on the submandibular gland area. Clinically, the exophytic mass penetrated the skin of the submandibular area. On MRI, the lesion occupied the left submandibular space and extended downward, protruding exterior to the subcutaneous fat layer, but the center of the lesion was located on the side of the skin and the growth exterior to the skin was prominent. Demarcation of the lesion and the submandibular gland was unclear. Histopathologically the epithelial nests and keratin production were seen, then the biopsy result was squamous cell carcinoma. The stroma of lesion showed a myxoid characteristic and some ducts showed metaplasia of the ductal cells, which suggested the gland-origin carcinoma. However, lots of keratin production and carcinomatous change of cells continuous to the normal epithelium of the skin, the skin-origin carcinoma invading into the submandibular gland area could not be excluded.

Purpose: To determine the clinical and radiological feature of peripheral osteoma of the mandible (POM) in a Korean population and to compare with previous reports. Materials and Methods: Sixteen cases of POM found in 15 Korean patients who visited Seoul National University Dental Hospital between 1980 and 1998 were reviewed to determine their clinical and radiological features. Results: The 15 patients, five males and ten females, ranged in age from 22 to 69 years, with a mean age of 40.7 years. Six POMs were located on the buccal side of the mandibular body and five on the lingual aspect of the mandibular body and five on the lower border of the mandible. The duration of the lesion ranged between 1 and 10 years. The size of the lesions, in their great diameter, ranged from 6 to 26 mm, with a mean of 14.1 mm. Six POMs were pedunculated, nine sessile, and one bell-shaped. Eleven POMs were compact types and five were cancellous ones. Conclusion: The clinical and radiological features of these Korean series were broadly consistent with those of non-Korean populations reported previously. The principal difference was that all POMs under 35 year-old age were compact types.(J Korean Oral Maxillofac Radiol 1999;29:523-532)

The purpose of this study was to observe the Art-Deco style art and hair-style. Art-deco design, which was popular in the 20th century, especially in the 1920s and 1930s, actively absorbed new forms, materials, and aesthetic values that come from technological developments and bridged the tradition to new pupblic culture. Art-Deco style art showed abstract and geometrical decoration tendency to meet modern concept and sense. The over all study on back grounds of Art-Deco style and its art works made possible to figure out the summary on formative characteristics of the style such as simplicity, exoticism, vivid colors, and functionalism. These findings suggest that hair styles borrow its characteristics or image from the past style to create new styles. It was found in the development of new hair styles that patterns or geometric motive appearing the Art-De´eco style are the source of rich design.

Objective: The Lispro insulin has faster onset of effects and shorter duration than the human regular insulin, an analog of human insulin. The differences in the pharmacodynamics between the two types of insulin in the continuous subcutaneous insulin infusion(CSII) with insulin pump for treating the Korean Type 2 DM patients were analyzed. The effects on the regulation of blood sugar, the amount of insulin injected, and the frequency of hypoglycemia were compared between the lispro insulin and the regular human insulin. Method and Material: One hundred and three Korean Type 2 DM patients were randomly divided into two groups, 49 Lispro insulin and 54 Regular insulin.(Table 1) Both groups were treated for 14 days. Also at a set time before meal, insulin was injected as bolus, using a portable insulin pump, in both groups, 15 minutes before for lispro insulin and 30 minutes before for human insulin The HbA1C, C-peptide, AC/PC, height and weight were measured for each patients at the time of admission. The peripheral blood sugar level and insulin injection profile were recorded 7 times per day for each patients. Results: After treating for 7 days and 14 days, the blood sugar level normalized in both groups. There weren't any significant differences in blood sugar levels in both groups at point of the study, and also there weren't any differences in the frequency of hypoglycemia. In order to maintain the normalized blood sugar level, the lispro insulin group had higher total daily insulin requirement than the regular insulin group after 14 days of treatment (0.90±0.35 vs 0.73±0.39u/kg/day, p<0.05) This difference is probably due to the difference in basement insulin requirements rather than prandial insulin requirements (0.32±0.1 vs 0.43± 0.09u/kg/day, p<0.001). Discussion: In the hospitalized Korean Type 2 DM patients with CSII treatment, continuous subcutaneous insulin infusion therapy using lispro insulin has convenience in usage compared to the regular insulin. However, there were not any differences in the blood sugar levels. Also lispro insulin requires more insulin in order to maintain normal blood sugar level, which is probably due to the increase in the basal requirement. Also there were not any difference in the frequency of hypoglycemia.
