  • In this paper, experiments to develop working clothes and evaluated, including the current and material-improved working clothes in relation to physiological functionality measurement. Experiments were conducted on subjects after wearing working clothes in an climate chamber, and the thermo-physiological response, such as human body temperature, micro-climate within the clothes, blood pressure, heart rate were measured. In this manner, the physiological functionality of improved working clothes was compared with that of current working clothes and evaluated. The summary of obtained results is as follows: For physiological functionality evaluation through material-improved working clothes, P working clothes showed significantly lower rectal temperature than C working clothes. For mean skin temperature, P's skin temperature was significantly higher than C's in the second half of the experiment. P working clothes's temperature around the thighs in Micro climate was significantly lower than that of the C working clothes. Also, humidity within the clothes showed similar trends. During the exercise period, C working clothes showed higher blood pressure than P, but P showed higher heart rates than C. Also, the oxygen uptake amount was higher in C than P during the exercise period, it explains that the energy consumption amount of P working clothes was smaller than that of C working clothes. Of the subjective evaluation, for temperature sensation, workers wearing P working clothes felt cooler. For humidity, C working clothes showed more humidity. For comfort, P working clothes were better, and for sense of fatigue, workers felt less tired wearing P working clothes. From results above, we can see that physiological functionality improved in the material-improved working clothes in the working clothes for construction site workers. The improvement of working clothes through functionality improvements not only will provide personal pleasantness to constriction site workers, but will also generate efficiency and productivity improvements at construction sites. All in all, the continuous study of functionality improvements in working clothes taking into consideration the human body's physiological responses is required.

  • To develop a new functional fruit wine, quality characteristics and physiological functionality of wild grape wine (WGW) were investigated and compared with that of foreign grape wine (FGW). Ethanol contents of WGW was 11.0%, similar to that of FGW(10.6%), but total acidity(0.67%) and total anthocyanin content($A_{520}$: 0.32) of WGW were higher than those of FGW(0.4%, 0.22). Antioxydant activity and SOD-like activity of WGW which is related in anti-aging functionality were 93.6% and 53.0%, respectively, higher than those of FGW(85.9%, 42.5%). from this results, we concluded domestic wild grape wine is very excellent functional fruit wine.

  • A new health paradigm may be evolving that would place emphasis on the positive aspects of diet, identifying components that are physiologically active and that contribute to the prevention of disease onset. It has been increasingly difficult to evaluate the impact of new bioactive materials and food products on the well being of society. Thus, testing systems for both health function and toxicity have become very elaborate, complex, and interrelated, making their interpretation difficult and open to controversy. To select the proper starting materials, to screen the appropriate health functionality and to determine the efficacy of product, a reliable, reproducible, sensitive and predictive assay is required. Particularly, in uitro assay is the first stage in preclinical test on physiologically active materials and have many advantages in terms of time, cost and convenience. However, several factors as well as some limitations should be considered in this assay system. This presentation, therefore, will address the use of in uitro assays for evaluating physiological functionality of foods coupled with general consideration.

  • To develop a new Gugija(Lycium chinensis Mill) product having increased value, the physiological functionality of various commercial Gugija products were investigated. In addition, an in vivo study was performed using spontaneous hypertensive rats(SHR) to examine the anti-hypertension effects of products. The results showed that antioxidant activity was highest in the methanol extract of Gugija leaf pickle(97.7%), and anti-hypertensive angiotensin I -converting enzyme(ACE) inhibitory activity was 80.4% in Gugija doenjang(soybean paste) water extract. Anti-cholesterolemia HMG-CoA reductase inhibitory activity was highest in the methanol extract of Gugija rice cake(66.1 %). However, SOD-like activity was below 30% in most products; and fibrinolytic activity was not detected or was very weak. Ultimately, we selected Gugija tea and Gugija wine as superior anti-hypertensive Gugija products, and subsequent in vivo testing was performed using SHR, comparing the tea and wine to Gugija fruit. Among them, the Gugija fruit demonstrated the best anti-hypertension effects in SHR.

  • The purpose of this study is to examine the functionality with material-improved working uniform(protocol, P) and current working uniform(control, C). Movement functionality evaluation of material-improved working uniform was carried out through sensory evaluation of working uniform. And Oxygen uptake was explored to different working uniform(P, C) in relation to a physiological functionality measurement. The results have been shown as follows: It was found that the workers feel uncomfortable with the parts of the wrist, the back width, the shoulder seam and the side in the current working uniform when they move their arms up and down, but the inconvenience has been reduced in the material-improved working uniform. And It was found that the workers feel uncomfortable with the parts of the back width, the wrist and the side seam of the jacket, and the waist, the hips and the thigh of the trousers in the current working uniform when they move their waist, but the inconvenience has been reduced in the material-improved working uniform. In the current working uniform, it was also found that they feel uncomfortable with the parts of the horse riding position in which they stand straight in their slightly bended knees, with the parts of the hips, the side seam, the thigh and the knees when they crouch down, and with the parts of the hips and the thigh when they put one of their legs onto a higher place. However, the inconvenience was reduced in the material-improved working uniform. Oxygen uptake, which was measured to assess physiological dressing functionality, was found to be higher when people work in an uncomfortable uniform than when they work in a uniform of better functionality by an increase in metabolic rate, which can be a cause of workers' inefficiency of fatigue.

  • Alcohol fermentation conditions for the production of plum wine were investigated and further, sensory evaluation and physiological functionalities of the plum wines were also determined and compared with those of plum liquors made by soaking plums in a mixture of commercial soju and 10% sugar for 15, 30, 60 and 120 days. Ethanol was produced maximally when 5% Saccharomyces cerevisiae was added to red plum juices and fermented at 25$^{\circ}C$ for 5 days. Angiotensin-converting enzyme inhibitory activity and fibrinolytic activity of the red plum wine were better than those of the plum liquors. However, the antioxidant activity, the SOD-like activity and the tyrosinase inhibitory activity of the plum liquors were better than those of the red plum wine. On comparing the red plum wine and the various kinds of plum liquors, the red plum wine was shown to be more acceptable by sensory evaluation.
