This study gave an insight into senior life plans and life satisfaction of the middle aged employee over 45 and under 60 years of age, listed in the KLIPS data for 2001 (4th year) and 2008 (11th year), so as to grasp levels of senior life plans of the middle aged employee as well as the longitudinal and short term effects of senior life plans on life satisfaction. The study findings showed as follow: First, For the period of years, the middle aged employees' health got worse and jobs got instable. Second, economic and physical senior life plans of the middle aged employee turned out below an average of three points which means preparations made below the normal level, whereas senior life plans in terms of relation and leisure and social activities came out with more than an average of three points, respectively, which means preparations made above the normal level. Third, as a result of looking into longitudinal effects of the 2001 senior life plans on life satisfaction, the level of senior life plans for leisure and social activities got higher, life satisfaction stayed higher in the year of 2001. In 2008, however, the higher level of economic plans for senior life came out with a higher rate of life satisfaction. From a short-term perspective, therefore, leisure and social activities to enjoy life impose a great impact on life satisfaction, whereas from a long-term viewpoint economic plans for senior life is regarded to be of greater importance.

An experimental study was conducted to evaluate the effect of freezing-thawing and air pollutants on the weathering of $TiO_2$ loaded granite. And the granite was coated with $TiO_2$ catalyst and tested. After freezing-thawing and air pollutants experiments the mineral compositions of the granite surface were lower then that of the fresh granite. Density of the weathered granite was steadily decreased from $2.60g/cm^3\;to\;2.55{\sim}2.56g/cm^3$, but absorption ratio and porosity were slightly increased. From these results, it was expected that granite could be weathered by freezing-thawing md air pollutants. In the case of $TiO_2$ was coated to the granite, the compressive strength and absorption ratio were slightly enhanced compared to the $TiO_2$ non-coated granite. Therefore, the $TiO_2$ coating method tested in this study considered to be a viable method to assist in the conservation of granite from environmental contaminants.

Resveratrol is a phytoalexin found in grapes, red wine, and berries. Resveratrol has been known to have many beneficial health effects, such as anti-cancer, neuroprotective, anti-inflammatory, and life-prolonging effects. However, relatively little is known about the effects of resveratrol on the regulation of ligand-gated ion channels. We have previously reported that resveratrol regulates subsets of homomeric ligand-gated ion channels such as those of 5-$HT_{3A}$ receptors. The ${\gamma}$-aminobutyric $acid_C$($GABA_C$) receptor is mainly expressed in retinal bipolar cells and plays an important role in visual processing. In the present study, we examined the effects of resveratrol on the channel activity of homomeric $GABA_C$ receptor expressed in Xenopus oocytes injected with cRNA encoding human $GABA_C$ ${\rho}$ subunits. Our data show that the application of GABA elicits an inward peak current ($I_{GABA}$) in oocytes that express the $GABA_C$ receptor. Resveratrol treatment had no effect on oocytes injected with $H_2O$ or with $GABA_C$ receptor cRNA. Co-treatment with resveratrol and GABA inhibited $I_{GABA}$ in oocytes with $GABA_C$ receptors. The inhibition of $I_{GABA}$ by resveratrol was in a reversible and concentration-dependent manner. The $IC_{50}$ of resveratrol was $28.9{\pm}2.8{\mu}M$ in oocytes expressing $GABA_C$ receptor. The inhibition of $I_{GABA}$ by resveratrol was in voltage-independent and non-competitive manner. These results indicate that resveratrol might regulate $GABA_C$ receptor expression and that this regulation might be one of the pharmacological actions of resveratrol on the nervous system.

The nutritional status is important for the physical and mental development of children. Children should have sufficient nutrient intake, specially for the developmentally disabled children. In spite of the importance not much research has been done for their food habit and nutritional status. In this study, nutritional status of the disabled children were examined, the number of children studied is 50 children in Seoul between 5 to 6 years old, of whom 11 were austism, 5 were mentally retarded children and 8 were down\\`s syndrome. In order to get the data questionnaires about the food habit and other related factors, and two days food records were used. Their mean height was 108.8$\pm$21.0cm and their average weight was 19.5$\pm$4.6kg. The proportion of study subject with problems of the food habits was 36%, without keeping the regular meal time was 16%, and having snacks 2-4 time daily was 56%. They chose confectionery and fruits as their favorite snacks. The proportion of study subject with the sensitivity to the food colors and smells when they ate was 54%, unskilled using spoon and fork was 58%, and having medications was 20%. When we asked them whether their parents used the food as compensation means or not, 32% of them said that they did it often or sometimes. For the nutrient intake, energy was 1,703 $\pm$ 511kcal, carbohydrate was 242.5 $\pm$ 69.3g, protein was 61.3 $\pm$ 17.5g, lipid was 50.0 $\pm$ 24.4g. As the nutrient intake, it was compared with RDA. The intake of vitamin A and calcium were below RDA. Intake of protein was more than 150% of RDA. The proportion of subject with more than 125% of RDA was 72% for the phosphorus, 62% for the protein, 60% for the Vitamin A and calcium were below 0.75 and that of the others was above 0.75. The mean adequacy ratio(MAR) was 0.88. As we sum up the results of the research, the developmentally disabled children were shorter and lighter than the reference, were having medications, had excessive appetites, and had unbalanced diets. Also they had the bad food habit. As for the nutritional intake, vitamin A and calcium intake were a little less than RDA, and protein and phosphorus intake were too much. With the results of the above research for the disabled children, we can conclude that there are need to take some necessary measures for those children. To establish some programs measures for their better food environment, it is thought that much more research should be done in the future. (Korean J Nutrition 34(2) : 188-197, 2001)

The purpose of this study is to have a preliminary study in order to identify changes in occupational performance skills and visual perception of patients with mild dementia, who have been provided with a group occupational therapy program, within community day-care center. The subjects of this study were 9 people with mild dementia living in a community. The period of administration was for 60 minutes per session three times a week during four weeks. We assessed their visual perception function(MVPT) and occupational performance(AMPS). One group pre-post test design was implemented as an experimental study to compare the results between before and after applying the group occupational therapy program within sensory, physical, creative activity. While a statistically significant difference between before and after the program of motor skills(occupational performance skill) is not shown, the visual perception function and occupational performance of patients with mild dementia improved significantly after receiving occupational therapy program(p<0.01, p<0.05). Therefore, it is possible to conclude that the group occupational therapy program is helpful to manage the occupational performance skills and visual perception of patients with mild dementia in community day-care center.

This historical research was conducted to analyze and categorize the titles which were presented in the journal, The Korean Nurse, from August 1962 to October 1995. Titles which were published with the purpose of educating graduate nurses and to update 0 their nursing knowledge to improve professional practice were included. There were 348 articles published from the beginning of publication in August, 1962 to October, 1995. All of the journals were reviewed except nine missing journals which were not available in any library. According to the characteristics of the articles in the periodical, the articles were divided into three periods. In each of the three peroids there were five categories: Subject, Clinical Practice, Fundamentals of Nursing Science, Nursing Administration, Others. These categories were adopted from Kim's(1994) division system which was developed to analyze nurse's insurance education program. The special feature peroid was from August, 1962 to December, 1974. In this period the articles were presented in an unorganized manner in the area of special feature or main issue. The largest area was the subject category(44%). The second largest area wes the fundamental of nursing science category(31%). From May, 1975 to December, 1977, the articles with the educational purposes were published in a designated area called continuing education. This period was labelled as the continuing education period. Among the published articles in this period, 45% focused on the subject category and 45% on the fundamentals of nursing science category. In this period the articles were focusing on nurses 'work in specific areas such as industry, nurses' aid schools, and nursing administration, articles on physical assessment first started to appear. The written continuing education period was from January 1978 to October, 1995. All the educational articles published in this area were analyzed and categorized into five areas as for the other periods. 48% of the articles focused on the subject category. In the mid-eighties, the term nurse specialist first.appeared and ten years later in 1990, the titles were subdivided into more specific titles, such as, home nursing, industrial nursing, emergency nursing, 23% were in the fundamental nursing science category and they dealt with nursing process, nursing theories, theory development. For the content analysis, three articles, one from each period, dealing with cardiovscular diseases were selected for comparsion. First, the special feature period, the title of the article was on diet therapy for cardiovascular disease patients, but instead the content was about rest, hygiene, medication, observation. They recommended rings to prevent bed sores, which is now considered as a cause for bed sores. In the continuing education period, the content was more focused on rehabilitation rather than general nursing .care. It became more specific, systematic, and organized compared with the special feature period. In the written continuing education period, the focus was on rehabilitation, not broadly, but very specifically on exercise. The further research on the content analysis is recommended along with a comparison of the trends in the Journal of Nurses Academic Society.

High blood pressure is an important determinant of the incidence of coronary heart disease, stroke, congestive heart failure, renal failure, and peripheral vascular disease. Recommendations for control of high blood pressure emphasize lifestyle modification, including weight control, reduced sodium intake, increased physical activity. Subjects who were normotensive (n=19, $47.2\pm9.0$ y, BP l16/81 mmHg) ,treatment hypertensive (n=33, $54.2\pm6.9$ y, BP 132/85 mmHg) and non-treatment hypertensive (n=14, $50.1\pm11.0$ y, 149/94 mmHg) recruited. Anthropometric assessment (height weight waist circumference, hip circumference, fat$\%$, fat mass, and lean body mass) and dietary assessments (using 3-days food records, daily nutrient intakes were inuysed by CAN PRO 2.0 were carried out. Blood and 24-hour urine were collected). Test of recognition for salt taste threshold were performed. In non-treatment hypertensive male subjects, weight, $\%$IBW, BMI, and waist circumference were significantly higher than those of normotensive and treatment hypertensive subjects (p<0.05) .Food habits were not significantly different among the three groups. Intakes of vitamin A, vitamin B,, and vitamin B, were significantly higher in normotensive group (p<0.05). Intakes of sodium and salt taste recognition threshold were the highest in normotensive group and the lowest in treatment hypertensive group (p<0.05). Blood levels of lipids and minerals were not significantly different among the three groups. Urinary calcium level of normotensive group were significantly higher than that of treatment hypertensive and non-treatment hypertensive groups (p<0.05). These results indicate that continuous management of hypertension by drug and non-drug treatment affects salt taste recognition threshold and reduced the consumption of sodium. However, dietary sodium intake exceed recommended sodium intake to prevent and treat hypertension. It is necessary to develop the lifestyle modification program that may have beneficial effects on hypertension treatment.

The main character of the Korean diet has been found to be low in protein both quantity and quality and high in carbohydrate. The purpose of this survey was to study the amount of salt intake related to the dietary pattern in Korea. The nutrition survey was conducted in a mountainous farming area located in Auhchun-ri, Gaebuk-myon, Changsoo-gun, Chunbuk Province, February 14-19 in 1973 (7 days). The precise weighing method was used in evaluating the kinds of foods and nutrients intake for 24 households during a three day period. The physical examinations were performed by a doctor on 120 persons and a detailed biochemical test on both blood and urine was made on 42 persons over 40 years old. The results obtained are summarized as follows: (1) Average nutrients intake of an adult per day: calorie intake was 2,446 Cal and its components-protein(61.1g) was 10 percent, fat(12.9g) was 5 percent and carbohydrate(521g) contributed 85 percent of the total calories. Other nutrients-calcium (443mg), thiamine(1.09mg), riboflavin (0.90mg), niacin (14.4mg) and vitamin C (63.2mg) were lower than the recommended daily allowance but vitamin A(2,083 I.U.), iron(11mg) and phosphorous(998mg) were slightly higher than that. (2) To evaluate the nutritional deficiences, clinical examinations were conducted. Angular stomatitis was present in 16.7 percent of those examiners. No edema was found. The rate of osteoarthritis, hepatomegaly diseases appeared in 20 percent of the total subjects and the symptoms appeared highest among those Iron 50 to 59 years old. (3) The following chemical components of blood serum were analyzed and found to be within the normal range: glucose, blood urea nitrogen, uric acid, total protein, albumin, globulin, bilirubin, total cholesterol, inorganic phosphate, alkaline phosphatase, sodium, potassium, chloride, calcium and lecithine dehydrase. One case of each of the following were found: hyperglycemia, hypocholesterolemia, renal problem, hypoproteinaemia and diabetes mellitus, and two persons were classified as showing hypoglycemia and hyponaturemia. (4) The sodium content in urine was 199.6 mEq/L, potassium content was 24.6 mEq/L. The sugar, pH and specific gravity in the urine was shown to be normal.

The purpose of this study was to identify the effects of an exercise program for lumbar stabilization on static and dynamic balancing and gait of stroke patients. The subjects were 27 stroke patients, who were divided into an experimental group(n=14) and a control group(n=13). The exercise was conducted for 30 minutes a day, four times a week, and for six weeks. The variables included static and dynamic standing balance and gait, which were verified before and after the lumbar stabilization exercise. Using the IBM SPSS(19.0 version), data were analyzed with t-test and two-way ANOVA to validate the differences before and after the experiment and between the groups. The significance level was set at α = .05 and the results of this study are as follows. First, statistically significant differences were found in the static standing balance after the exercise (P< .05). Second, there were statistically significant differences in the dynamic standing balance after the exercise (P< .05). Third, statistically significant differences were found in the gait of the patients after the exercise (P< .05). In addition, the interactions between the two groups showed significant differences. These results suggest that stroke patients need a variety of lumbar exercises and that the lumbar stabilization exercise can improve physical treatment and health of the patients, having positive effects on their quality of life. Further studies are necessary to explore the applications of various lumber exercises.
