Every year the number of the elderly increases in Korea thanks to the improvemen of social and economical levels and the development of medicine. However, many problems such as insufficent care and the isolation of the elderly have been commonplace. This trend exists not only because of increased lifespan but also the changing social structure of the nuclear family. Accordingly, inspite of the development of medicine, geriatric diseases including circulatory diseases are increasing in proportion of elderly population, as well as the severity. Therefore, it is important to emphasize that health care programs provide the best possible health care and functional capacities in terms of healthy elderly lifestyles. Especially, the phenomena of aging and geriatric diseases taking place with the elderly naturally are affected by lifestyle and the drastic changes in exercise patterns. This study aims to improve geriatric health by introducing a rhythmic movement program for the elderly to estabilish a health-promoting self-care system and by developing quality of life, perceived health status, their physical and physiological functions and emotional state. The theoretical framework used in this dissertation is derived from the Health-Promoting Self-Care System Model (Simmons, 1990), which integrates the Self-Care Deficit Nursing Theory (Orem, 1985), the interaction model of Client Health Behavior (Cox, 1982) and the Health Promotion Model (Pender, 1987). As a quasi-experimental design, the nonequivalent control group pretest-posttest design is utilized for this study. The subjects of this study consist of 64 people, over 65 years old who live in 2 nursing homes for the aged located in S city , Kyong-gi province and volunteered for this study from July, 12, 1999 to September, 17, 1999. They are divided into two groups：33 in the experimental group and 31 in the control group. The experimental group particpated in the Rhythmic Movement Program at the nursing home, which was comprised of 45 minutes a session, 5 sessions a week during 9 weeks. In order to measure the results of the Rhythmic Movement Program, aspects of perceived health status, balance, flexibility, grip strength, leg strength, heart rate, blood pressure, depression, anxiety and the quality of life were measured before and after participating in the Rhythimic Movement Program for the experimental group after 9 weeks, as well as the control group. The collected data were processed by SPSS PC+ and analyzed by the X2 test, t-test, ANCOVA and the Pearson Correlation Coefficient. The results of this study are as follows: 1. The perceived health status conditions in the experimental group show statistically significant improvement when compared to the control group (F=17.51, p=.000). 2. The physical and physiological functions, that is, balance (F=17.51, p=.000), flexibility (F=8.01, p=.006), grip strength (F=3.21, p=.018) and leg strength (F=25.78, p=.000) in the experimental group are higher than the control group. The vital signs, that is, the number of heart rate (F=.022, p=.884), systolic pressure (F=1.73 p=.193), and diastolic pressure (F=2.74, p=.103) in the experimental group compared to the control group decreased, but doesn't show statistically significant differences. Immune responses (F=5.13, p=.003) showed statistically significant increases in the experimental group when compared to the control group. 3. The emotional state are improved, that is, degree of depression (F=11.56, p=.001) and degree of anxiety (F=9.14, p=.004) in the experimental group showed statistically significant decreases. 4. The quality of life in the experimental group (F=3.03, p=.037) showed statistically significant differences compared to the control group. 5. The observations of the relationships among the perceived health status, emotional state , the quality of life, the relationships between the perceived health status, the degree of depression (r=-.653, p=.000) and the degree of anxiety (r=-.786, p=.000) were in contrary propotions, while the relationships between the perceived health status and the quality of life (r=.234, p=.008) were in direct propotion. In conclusion, the Rhythmic Movement Program used in this study for geriatric nursing care is simple and safe for application to the elderly and shows significant effects by implementing 5 sessions a week for 9 weeks. The Rhythmic Movement Program improves the quality of life, maintains as well as improves the physical and physiological fuctions and emotional state, therefore this program is strongly recommended for positive applications for independant geriatric nursing health care.

This study was performed to investigate the effect of germinated Ilpum rough rice extract on blood glucose in C57BL/KsJ-db/db mice. The mice were divided into several groups: normal control (NC), diabetic control (DC), those fed with 0.25% germinated Ilpum rough rice extract (DM-0.25%GIRRE), those fed with 0.5% germinated Ilpum roughrice extract (DM-0.5%GIRRE) and those fed with 1% germinated Ilpum rough rice extract (DM-1%GIRRE). After 8 weeks of treatment, body weight, water intake, and diet intake of the DM-1%GIRRE group were significantly lower than the other DM groups. Blood glucose levels of the DM-1%GIRRE group were significantly lower compared to the DC group. Fasting blood glucose HbA1c level and total glucose tolerance test were significantly lower in the DM-1%GIRRE groups compared to the DC group. There was no significant difference in serum insulin level among each group. Therefore, the results of this study demonstrate that germinated Ilpum rough rice extract alleviates many of the symptoms of diabetes in genetically obese mice and may offer a possibility as a therapeutic supplement for the normalization of blood glucose levels in humans with hyperglycemia. It may also have beneficial effects in patients with non-insulin-dependent diabetes mellitus.

The Present study was attempted to investigate the Possibility of modification of functional properties of the rice flour by crosslinking proteins using microbial transglutaminase (mTGase) derived from a variant of Streptoverticillium sp. MTGase was added at various levels (3,000, 5,000, 7,000 and 10,000 ppm) during making noodles mixed with the rice flour. Mixograph and farinograph showed that imported wheat flour (IWF) had strong dough stability, while the rice flour showed very weak dough strength. However addition of mTGase (3,000, 5,000 and 7,000 ppm) resulted in improvement of dough stability of the rice flour. Texture profile analysis (TPA) results indicated that most of texture parameters (gumminess, chewiness and hardness) of cooked noodles prepared from the rice flour were significantly lower than those of noodles prepared from IWF. However, by addition of mTGase (at the levels of 3,000, 5,000, 7,000 ppm) dough stability and all the TPA values and sensory score (at the level of 7,000 ppm mTGase) on chewiness and hardness of cooked noodles made with $30\%$ rice flour were improved significantly. These results suggest that dough stability and texture of rice noodles as well as sensory characteristics could be improved by addition of mTGase to the rice flour.

A mechanically pressed juice of Bokbunja (Rubus coreanus Miq.) extract was prepared using 70% ethanol solution. The extract was subjected to gamma-irradiation treatment (20 kGy) and investigated for its change of color and biological activities. Hunter $L^*$ values of the irradiated Bokbunja extract were increased in comparison with the non-irradiated extracts, and the $a^*\;and\;b^*$values decreased by the irradiation treatment. The content of the total phenolic compounds in the non-irradiated and irradiated extracts were 58.4 and 56.5 mg/g, respectively. The 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activities of non-irradiated and irradiated extracts at a 250 ppm level were 80% and 79%, respectively. Lipid oxidation was retarded by addition of Bokbunja powder. Nitrite scavenging activity was the highest in the Bokbunja powder at pH 1.2 and the effect was not changed by irradiation. The Bokbunja powder showed antimicrobial activity against Salmonella Typhimurium and Bacillus cereus. However, irradiation of Bokbunja did not affect any physiological functions (p>0.05). A Salmonella mutagenicity assay indicated that the irradiated Bokbunja extract did not show any mutagenicity. Therefore, Bokbunja extract could be used in various applications as a functional material, such as ingredients of food and cosmetic, compositions with functions.

In present paper, we examined the flayer constituents and functionality of two stage enzyme hydrolysates (TSEH) of purplish clam and oyster, and also examined reappearance of oyster flavors through repreparation of individual flayer constituents. Total free amino acid contents in TSEH was $1943.0mg\%$ for purplish clam and was $5066.2 mg\%$ for oyster, respectively, Major free amino acids in purplish clam extracts were taurine, glutamic acid, glycine, alanine, Iysine and arginine, and in oyster extracts were taurine, asparagine, glutamic acid, valine, leucine, alanine, Iysine and arginine. As for nucleotides and related compounds, AMP was the principal component though small amounts in TSEH of purplish clam and oyster, and also contents of TMAO, total creatinine, and betaine were $41.2 mg\%,\;35,9 mg\%$ and $220.9 mg\%$ for that of purplish clam and $3.51 mg\%,\;33.4 mg\%$ and $380.9 mg\%$ that of oyster, respectively. The major inorganic ions in TSEH of both samples were Na, K, P, Cl and $PO_4$, and major non-volatile organic acid was succinic acid. The TSEH of purplish clam and oyster revealed very higher inhibition effect ($84.1\%,\;77.0\%$) in ACE inhibition than that ($0\~44.7\%$) of water and autolytic extract. A synthetic oyster extract prepared from pure chemicals on the basis of the analytical data on the TSEH, satisfactorily reproduced the taste of the natural extract except for a slight lack of mildness and odor. From the omission test the major taste compounds of oyster extract were free amino acid and inorganic ions. The quaternary ammonium bases, nucleotides and related compounds seemed to net an auxiliary role in taste of that.

The concept of national security and the fundamental system for crisis management have departed from traditional methods and the importance of a national critical infrastructure crisis management has been emphasized. A national critical infrastructure crisis means a situation where human resource, material and functional system that may have a material effect on the critical functions of the government, the vitality and integrity of society, national economy and the safety of the public becomes disabled due to causes such as terrorism or major disasters. Although North Korea had been subject to numerous rounds of negotiations and sanctions as it continually developed nuclear weapons since the 1960s, it has also showed off its nuclear armaments through successful nuclear testings and missile launches. As the development and threat of North Korea's weapons of mass destruction becomes more noticeable and the range of its risk expands, this study focuses on the potential for an absence of leadership for national crisis management where the country's leadership, which should serve the critical role and function of handling national crises, becomes completely destroyed by the unexpected initial attacks by North Korea. As a result, the purpose of this study is to propose safety measures for the country's leadership in preparation for North Korea's threat of nuclear weapons by examining the concept and degree of risk of weapons of mass destruction with a focus on nuclear weapons, analyzing the substance of the threat of North Korean nuclear weapons and evaluating such threat. In conclusion, first, to ensure the normal functioning of a national crisis management system in the event of a national crisis, we must seek safety measures that conform to the scope and succession order of the leadership of the national crisis management for an Enduring Constitutional Government (ECG) and the Continuity Of Operations (COOP). Second, in the event of a national ceremony, the gathering of the country's leadership all together in an open place should be avoided. In unavoidable circumstances, the next in rank that will act on behalf of the current leader should be designated and relevant safety measures should be taken. Third, during time of peace, in preparation for national crises, the scope of protection for the country's leadership should be prescribed and specific security and safety measures should be implemented. Fourth, the succession order for acting president in the case of the death of the president pursuant to Articles 71 and 26(1) of the National Government Organization Act should reconsidered to see whether it is a reasonable provision that takes into consideration a national crisis management that corresponds to the threat of North Korean nuclear weapons and weapons of mass destruction. Pursuant to the Basic Guidelines for National Crisis Management set out under Presidential Directive No. 229, the Korean government is currently operating a case-by-case "crisis management standard manual" and its sub-manuals and has also prepared the Presidential Security Service's security and safety measure regulations regarding the acting president. Therefore, the Korean government should actualize the above points in the case-by-case crisis management standard manual and security and safety measure regulations regarding the acting president to implement and legislate them.

This study was conducted to examine the effects of dietary Mogchotan(the mixture of charcoal and pyroligneous acid, 80:20, w/w) supplementation on fattening performance, fatty acid composition and the physico-chemical characteristics of meat in pigs. The present study was also stressed to investigate the possibility of industrial utilization of charcoal and pyroligneous acid as a livestock feed additive. Weight gain and feed conversion in pigs fed the Mogchotan supplemented diet were higher than those of the control group. In fatty acids composition, palmitic acid(C16:0) contents of Mogchotan treatment groups were lower than that of control group. However, Mogchotan supplementation increased C16:1, C18:0, C18:1, C18:2 and C18:3 contents when compared with control group pigs. Also, Mogchotan supplementation groups decreased saturated fatty acids level than control group. On the other hand, Mogchotan supplementation showed higher unsaturated fatty acids value, especially polyunsaturated fatty acids value compared to control group. The carcass pH of pigs fed the Mogchotan tended to be higher than control, but was not significantly different. The water holding capacity was significantly higher in pigs fed the 3.0% Mogchotan-supplemented diet than those of other treatment groups(p<0.05). Altogether, it has been suggested that dietary $1{\sim}3%$ of Mogchotan supplementation improved the fattening performance and meat quality in pigs.

his experiment was carried out to evaluate the effects of nitrogen top dressing levels on the growth, feed value, and anthocyanin content for developing functional feed of colored barley. A colored barley cultivar, Boanchalbori, was tested in this experiment. Nitrogen top dressing levels was six (0, 20, 40, 60, 80, 100%) and top dressing time was a regeneration time. In case of productivity, heading data was get behind and dry matter rate was significant decreased with higher nitrogen top dressing levels (p<0.05). Fresh yield, dry matter yield and TDN yield was increased with higher nitrogen top dressing levels, but not significant. In case of feed value, crude protein content was significant increased with higher nitrogen top dressing levels (p<0.05), and higher in the order of spike, whole and leaf culme of the plant. Percent NDF and ADF was decreased with higher nitrogen top dressing levels in leaf culme, but no difference in spike and whole (p<0.05), and higher in the order of leaf culme, whole and spike of the plant. TDN was increased with higher nitrogen top dressing levels in leaf culme, but no difference in spike and whole (p<0.05), and higher in the order of spike, whole and leaf culme of the plant. Total anthocyanin content was significant decreased with higher nitrogen top dressing levels in leaf culme and whole (p<0.05), and higher in the order of leaf culme, whole and spike of the plant. Specially, cyanidin-3-glucoside (C3G), delphinidin (Del), malvidin-3-glucoside (M3G) and malvidin (Mal) show a significant decrease. So there are an accumulation of anthocyanin in the culm, and standard nitrogen top dressing levels dressing on the regeneration time for produces high anthocyanin content of the colored barley.

Myelophycus simplex Papenfuss is distributed over the northern Pacific and southern coast of Korea, and is a member of the brown algae family. The objective of this study was to investigate the effect of M. simplex methanol extract on adipocyte differentiation and adipogenesis in 3T3-L1 preadipocytes. Treatment with M. simplex methanol extract significantly suppressed terminal differentiation of 3T3-L1 preadipocytes in a dose-dependent manner, as confirmed by a decrease in lipid droplet content observed by Oil Red O staining. Also, the M. simplex methanol extract significantly suppressed the triglyceride content of 3T3-L1 preadipocytes in a dose-dependent manner. Treatment with 300 and $500{\mu}g/ml$ of M. simplex methanol extract caused a 42% and 76% reduction in lipid droplet content, respectively. In order to understand the anti-adipogenic effects of M. simplex methanol extract, the changes in the expression of several adipogenic transcription factors, including peroxisome proliferator-activated receptor (PPAR) ${\gamma}$-cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding protein (C/EBP) ${\alpha}$ and ${\beta}$, were investigated using immunoblotting. M. simplex suppressed the expression of $PPAR{\gamma}$, $C/EBP{\alpha}$, and $C/EBP{\beta}$ proteins compared with control. Therefore, the results of this study suggest that M. simplex methanol extract inhibits adipocyte differentiation and thus may have applications as a potential source for an anti-obesity functional food agent.
