The present study was carried out to evaluate the physiological effects of seaweed supplementation on blood glucose levels, lipid profile, and antioxidant enzyme activities in subjects with type 2 diabetes mellitus. Subjects were randomized into either a control group or a seaweed supplementation group. Pills with equal parts of dry powdered sea tangle and sea mustard were provided to the seaweed supplementation group three times a day for 4 weeks. Total daily consumption of seaweed was 48 g. We found that total dietary fiber intake was 2.5 times higher in subjects receiving seaweed supplementation than in the control group. Accordingly, fasting blood glucose levels (p<0.01) and 2-hour postprandial blood glucose measurements (p<0.05) were decreased significantly in those ingesting seaweed. Furthermore, the serum concentrations of triglycerides were decreased and high-density lipoprotein cholesterol was increased significantly in seaweed supplement group (p<0.05). However, the concentrations of total cholesterol and low-density lipoprotein cholesterol were not affected by seaweed supplementation. The level of thiobarbituric acid reactive substances in erythrocytes was significantly lower with seaweed supplementation compared to controls (p<0.05). Catalase and glutathione peroxidase activities with seaweed supplementation were higher than the controls (p<0.05), but superoxide dismutase activity was not affected. We, therefore, conclude that ingestion of seaweed influences glycemic control, lowers blood lipids, and increases antioxidant enzyme activities.

Purpose: The effects of aroma massage on pain, activities of daily living, and fatigue were investigated in the patients who have knee osteoarthritis. Method: A quasi-experimental design with non-equivalent control group pretest-posttest measures was used. Twenty one and twenty subjects were included in control and experimental group, respectively. Subjects in experimental group had aroma massage which used lavender, chamomile, and ginger oil on painful knee. They were encouraged to implement aroma massage at least two times a day for 2 weeks. Subjects in the control group had conventional oil massage implementing by exactly same method as did in the experimental group. GRS(graphic rating scale), Korean version of WOMAC (Western Ontario and McMaster) osteoarthritis index, and MAF(multidimensional assessment of fatigue) were used to measure the outcome variables such as pain, activities of daily living and fatigue, respectively. Results: After 2 weeks, those in the experimental group reported significantly less pain and fatigue and better activities of daily living than those in the control group. Conclusion: Based on these results, aroma massage could be recommended as a self managed intervention for the patients with knee osteoarthritis.

This report is intended to describe as brief as possible the result of study on purity of the Korean Bee Honey. Purity of bee honey was measured by scaling the enzyme activities of two different honey groups: such as, the standard group and control group each including the samples of honey originated from the resource of acarcia, chestnut or miscellaneous origin. The samples of honey were collected from different sources: to wit, honey belonging to the standard group were collected from the township of Seoboo, Yangju county, Kyunggido province, Korea, while honey belonging to the control group were collected from the street side shops, market or the companies producing the secondary food from honey. The results of this study were summarized as follow: 1. It was found that honey belonging to the standard group contained less moisture than those belonging to the control group. Republic of Korea Ministry of Health and Social Affairs Food Control Regulation stipulates that honey must contain moisture less than 20%. The samples of' both groups contained moisture more than 20%, although honey belonging to the control group were relatively more so than honey belonging to the standard group. 2. Honey belonging to the standard group were found stronger in sugar reduction activities than those belonging to the control group. It was also noted that honey of acracia origin was strongest in reduction activities of the three different origin in the same group. 3. $\alpha$-Amylase and $\beta$-amylase were discovered to have activated more strongly in honey belonging to the standard group than those belonging to the control group. The enzyme activitie, varied depending on the origin of plant where honey comes from. For instance, honey of miscellaneous origin indicated the strongest activities in $\alpha$-amylase while honey of chestnut origirt indicated strongest in $\beta$-amylase.

Nucleic acid and protein biosynthese of the glucose-bleached Chlorella cells in relation to the process of the chloroplast reformation were traced, by measuring the changes in the amounts of cell constituents and nuclease activities of the cells during the greening process. The contents of RNA and protein of the glucose-bleached cells decreased significantly, shile the contents of nucleotides and amino acids of the cells increased to compared with those of the control, showing that the biosynthetic activities of RNA and protein of the cells were inhibited severely in the glucose-bleaching process. In the early greening process of the glucose-bleached Chlorella cells the contents of RNA and protein of the cells increased significantly, while the contents of nucleotides nad amino acids of the cells increased to compared with those of the control, showing that the biosynthetic activities of RNA and protein of the cells were inhibited severely in the glucose-bleaching process. In the early greening process of the glucose-bleached Chlorella cells the contents of RNA and protein of the cells increased significantly wihout any increase in the chlorophyll contents showing that the massive biosynthese of RNA and protein proceed prior to the chlorophyll bioynthesis in the cells. The phosphate contents in the DNA fraction of the glucose-bleached cells decreased, but the contents of acid-insoluble polyphosphate increased to compared with those of the control in the early greening porcess, exhibiting that the incorporation of the phosphorus from acid-insoluble polyphosphate into DNA was retarded. In the greening process of the glucose-bleached cells the ribonuclease nad deoxyribonuclease activities of the cells decreased to compared with those of the control, although the initial activities of the both enzymes in the cell were far great compared with the control. Although the initial phosphate contents in the lipid fraction of the glucose-bleached Chlorella cells were more great than the control, the phosphate contents in the lipid fraction of the cells decreased in the early greening process to compared with control, and then increased in the late developmental stages in which massive chlorophyll biosynthesis occured.

To increase antioxidant activity and physicochemical quality characteristics, four kinds of berries (blueberry (BEB), blackberry (BKB), cranberry (CNB), raspberry (RSB)) with antioxidant activities were used to replace beet (B) in existing ABC juice. In the experimental group, the pH was decreased while the content of soluble solids was increased significantly. Total polyphenol content was significantly increased in all experimental groups compared to that in the control group. The control group had the lowest polyphenol content at 14.723 ㎍ GAE/g, whereas the blackberry replacement group had the highest polyphenol content at 67.12 ㎍ GAE/g. The total flavonoid content was the lowest in the control group at 8.98 ㎍ QE/g but the highest in the blackberry group at 50.47 ㎍ QE/g. All experimental groups showed significantly higher antioxidant activities than the control group. DPPH & ABTS radical scavenging activities were the lowest in the control group at 15.69% and 19.55%, respectively, but the highest in the blackberry group at 48.24% and 59.43%, respectively. SOD-like activity was also the lowest in the control group at 14.12%, but the highest in the blackberry group at 48.18%. When comparing experimental groups, antioxidant activities (DPPH, ABTS, SOD) and antioxidant components (total polyphenols and total flavonoids) were in the order of BKB > CNB > RSB > BEB > Control. In conclusion, the new ABC juice containing four types of berries is enriched in antioxidants with significantly improved antioxidant activities and physicochemical quality characteristics.

A common control model used to implement computer integrated manufacturing(CIM) is based on the hierarchical decomposition of the shop floor activities, in which supervisory controllers are responsible for all the interactions among subordinates. Although the hierarchical control philosophy provides for easy understanding of complex systems, an emerging manufacturing paradigm, agile manufacturing, requires a new control structure necessary to accommodate the rapid development of a shop floor controller. This is what is called autonomous agent-based heterarchical control. As computing resources and communication network on the shop floor become increasingly intelligent and powerful, the new control architecture is about to come true in a modern CIM system. In this paper, heterarchical control is adopted and investigated, in which a controller for a unit of device performs three main functions - planning, scheduling and execution. Attention is paid to the planning function and all the detailed planning activities for heterarchical shop floor control are identified. Interactions with other functions are also addressed. In general, planning determines tasks to be scheduled in the future. In other words, planning analyzes process plans and transforms process plans into detailed plans adequate for shop floor control. Planning is also responsible for updating a process plan and identifying/resolving replanning activities whether they come from scheduling or execution.
