This study was conducted to estimate the effects of self-care program on knowledge and symptoms related hypertension self-care and physiological index in essential hypertensive patients aged between 35-74 year. The subjects for the experiment group and the control group of this study were 70 men and women selected through random sampling from adults at Sangju Red Cross Hospital in Gyeongsanbuk-do, and the experiment was carried out during the period from the 15th of September to the 30th of April in 2002. This study measured systolic and diastolic blood pressure (SBP, DBP, the mean value of the two measures) and total cholesterol (TC) and surveyed the subjects' diet and life style in relation to hypertension using a self-report questionnaire. In order to study the significance of the effects of self-care program, the author carried out t-test, paired t-test, ANCOVA, chi-square analysis and effectiveness index (EI) analysis. Results of the study are as follows: The experiment group got higher mean scores than the control group in the degree of low sodium intake and the degree of high calcium and high potassium intake, and the difference was statistically significant(P<0.05). The effectiveness index of the self-care program in smoking was 0.797 at the 1st posttest and 0.601 at the 2nd posttest, and in physical activities 0.600 at the 1st posttest and 0.849 at the 2nd posttest. The rate of regular antihypertensive drugs intake of the experimental group was higher than that of the control group. and the effectiveness index of the self-care program was 0.715. The mean score of the systolic blood pressure of the experimental group was lower than that of the control group, and the difference was statistically significant(P<0.05). In conclusion, these findings support usefulness of self-care programs in reducing systolic blood pressure and in promoting self-care related to diet and life style for treating and preventing hypertension.

This study was performed to investigate effects of raw sea tangle products on idiopathic constipation. A total of thirty-eight women participated voluntarily in this study. They were placed into one of four groups by their total colonic transit time (TCTT) to make the four groups have the same TCTT. In the first trial, the subjects in Control group were fed 3 times of 150 mL of mineral water per day for 2 weeks, those in +Control group were fed a kind of stool softener as well as the same mineral water for 3 times, those in STT group were fed 3 times of 150 mL of sea tangle tea and those in STB group were fed 3 times of 150 mL of sea tangle beverage. After 6 weeks, a second trial was performed for another 2 weeks. Although the TCTT of the group exposed to of KolomarkTM was not significantly reduced, the subjects in STT group answered that their evacuation activities were significantly improved; evacuation frequency was increased, stool hardness was reduced, evacuation straining was lessened, stool amount was increased, incomplete sense of evacuation was lessened, and major evacuation time was improved like those in +Control group. The results imply that it is worthy to develop some products of raw sea tangle such as STT, which are effective in treating or preventing constipation.

Phenolic antioxidants are effective stabilizers that provide excellent long-term heat stability by preventing thermo-oxidative degradation during processing and service life. However, under a selected set of circumstances, certain types of phenolics have been susceptible to discoloration due to prolonged storage in an environment containing oxides of nitrogen. It is investigated that the effect of addition of secondary antioxidant and chemical structure of primary antioxidant on discoloration of amorphous poly-${\alpha}$-olefin (APAO), which is especially prone to be decomposed in high processing temperature. From the result, it is concluded that a higher level of steric hindrance of phenolic antioxidant provided by long alkyl chain allows a more enhanced synergic effect with secondary antioxidant.

The antioxidant and neuronal cell-protective effects of hot water extract from commercial buckwheat tea (CBTE) were evaluated. The 2,2'-azino-bis(3-ethyl-benzthiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, ferric reducing antioxidant power (FRAP), and malondialdehyde (MDA) inhibitory effect of the CBTE increased in a dose-dependent manner. The Intracellular reactive oxygen species (ROS) accumulation that resulted from hydrogen peroxide ($H_2O_2$) treatment more significantly decreased when CBTE was present in the media than when the PC12 cells were treated only with $H_2O_2$. In the neuronal cell viability assay using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazoliumbromide (MTT), the aqueous extracts showed a protective effect against $H_2O_2$-induced neurotoxicity, and the lactate dehydrogenase (LDH) release into the medium was also inhibited by CBTE. The total phenolics of CBTE was 9,608.10 mg/100 g, and the major phenolic compounds were rutin (13.42 mg/100 g) and quercitrin (0.90 mg/100 g). These data suggested that CBTE, including the aforementioned phenolics, may be useful in reducing the risk of neurodegenerative disease.

This study examines the removal effects of solvents which were applied on three adhesives and three filling materials for ceramics. The chosen materials are Cemedine C, Loctite$^{(R)}$ 401$^{TM}$, Araldite Rapid Type, plaster of paris, CDKI 520A+B, Araldit$^{(R)}$ SV427-2+HV427-1. For the first examination, each different materials were soaked into different solvents, and then the soften level were compared by compressive pressure. The result of the first exam showed that Cemedine C was dissolved easily in acetone. Furthermore Araldite, CDK and SV427 were soften efficiently by Dichloromethan, Tetrahydrofuran and DMX(Dichloromethan+Methanol+Xylene). However, Loctite and plaster were not able to make sample for the first test. Therefore, the second test carried on only. The second examination, chosen effective solvents from the first test were applied with two different methods; soaking and saturated atmosphere. Almost every sample could removed by soaking method in ten minutes, and saturated atmosphere method needs 24 hours for the safety.

The purpose of this paper is to analyze the effect of government R&D subsidies on business performance of SMEs in the field of Land, Infrastructure, and Transport. To this end, based on domestic and foreign literature, the performance derived through R&D was classified as primary and secondary parameters, and the commercialization program operated by the government was set as a moderating variable. Regression analysis, double mediation analysis, and moderated mediation effect analysis were used to confirm the effect of government R&D subsidy on project performance and process. As a result of this study, it was confirmed that government R&D subsidies have a significant effect on corporate management performance, and it was confirmed that the primary performance such as papers and patents and the secondary performance such as prototypes and legislative revisions have a double mediating. In addition, when the commercialization program was applied to the first and second parameters, it was confirmed that it played a moderated mediating effect. The results of this study are expected to be used when establishing government R&D support plans to expand business performance and economic effects in the future.

Master packaging system consists of an inner individual package and secondary outer package. During the stages of chilled transport and distribution, the combination of primary individual package and secondary package was used to maintain a modified atmosphere for shiitake mushrooms. During the retail stage at higher temperature ($25^{\circ}C$), the primary individual package was exposed to display conditions after dismantling of the secondary packaging. The master packaging system was constructed to contain eight individual $30-{\mu}m$ thick polypropylene film bags of 500 g shiitake mushrooms inside a $40-{\mu}m$ low-density polyethylene bag. Carbon dioxide absorbent material [$Ca(OH)_2$] and/or moisture absorbent (superabsorbent polymer) were designed in their required amounts based on respiration characteristics and then applied to the outer secondary packaging in sachet form. Gas concentration of the packaging, temperature, and humidity were monitored throughout transport and storage. The quality of shiitake mushrooms was measured at the retail stage to determine the packaging effect. During the distribution stage of 108 h, $O_2$ and $CO_2$ concentrations in the master packaging system were maintained at 9~11% and 1~4% in the inner packaging, respectively, which are good for quality preservation. Compared to the control, the master packaging with $CO_2$ and/or moisture absorbents improved mushroom preservation and particularly reduced decay.
