Current statistics reveal remarkable prolongation of the average longevity in this country for the past decade. Welfare of the aged is no longer sole concern of the person or/and family. but has aroused social concern on the community and national level. This study was designed to assess social, economic and emotional needs of the aged. and to identify problems they are confronting. Data were gathered through questioning 273 subjects living in Seoul from July 25, to August 31. 19 80. Frequencies and percentile scores were analysed to describe the fact. and the significance of int or-variable differences was tested by Chi-square method. Results are : 1. Majority of the subjects (male : 65.38%). (female : 62.13%)“talk about past experiences”to re-collect their past days, the difference between male and female respondents was not significant. 2. Except few who earn their pocket money (4.21%). majority were doing household errands (34.52% ) and looking after their garnd children (29.26 ％）. Main sources of their pocket money revealed to be their children (84.02%) and their own savings (24.64% ). Except few (15％）engaged with social activities directly or indirectly. leisure hours are spent in chatting with aged neighbors (44.81%). Highest in the rank order on the joyous moments for the aged revealed to be when the members of family living apart paying a visit (male : 37.5%, female : 63.72%)difference of male and female was significant ( P<0.05). Among female respondents. significant difference between age group was revealed (p<0.05). 3. Majority prefered sin91e houses (84.30% ). as residential environment. the suburban (36.26% ) area was the filet in the rank order : difference between age group and the educational status were not significant. Majority of respondents revealed to have their own room in the house. The first preference was given to live with their children (68.86%). Memory of the past (37.36% )revealed to be the highest in the rank order among the reasons why they dislike moving the house. 4. Majority favored current welfare benefts provided for the old age. however. the ideal way to live at their old age they responded was to live on their own savings (50.54%). 5. Majority revealed to be daunted occasionally (62.27%) by not being less active (34.16%) socially and by poor physical health(29.75%). Male and female differ in the causes of loneliness significantly (P <0.001) : retirement (37.89%) in ale and helpessness (43.05%) in female revealed the highest in the rank order. Majority talk over their feelings with aged neighbors to overcome the loneliness. 6 Majority were in favor of planting and looking after pet animal in the house. however. male and female differ in the kind significantly (p <0.001), 7. Majority think about death and dying occasionally or more (84.11% ). Many of the respondents believes in the life after life (53.49%) : female revealed to be significantly higher (p <0.01). and subjects with christian belief were significantly higher than non-christians (P<0.001). Attitude towards death and dying differs significantly between male and female (P <0. 001) and between christians ans and nonchristians (p <0.001). Highest preference was given to simple funeral (69.85%). Precious heritage that they would pass on to their descendants was onoscience and ethical value(57. 51%) : christian response as the first value was christian belief (52.38%).

Whole and stem-off cherry tomatoes were packaged using perforated films(LF05, LF10, LF20, and LF40). Gas composition(ethylene, $O_2$, and $CO_2$), firmness(compression and penetration force), color, brix degree, acidity, and total microbial counts were assessed during storage at $10^{\circ}C$ and 85% relative humidity. Gas composition varied with film gas permeability, indicating that modified atmospheric(MA) conditions were achieved. Firmness fell during storage; samples packed using LF05 showed the lowest firmness, corresponding to low gas transmission conditions. L(lightness) and a(redness) values respectively decreased and rose slightly with increasing storage time, but the b(yellowness) values fell notably. Film permeability significantly affected acidity and soluble solid levels. When LF40 packaging was used, acidity and brix scale changes were similar to those seen after PET container packaging. Total microbial counts increased with time after packaging in most films, and pretreatment differences were not significant. Microflora varied between stem on/off tomatoes. Skin wrinkling and juice appearance were common in tomatoes stored in PET containers and LF films of low gas permeabilities(LF05, LF10, and LF20). White molds were partially found on stem-on tomatoes stored using packaging systems. When film packagings were compared, LF40 was optimal, permitting minimal pretreatment yet offering maximal sanitation.

This study was carried out to estimate the effects of preservatives (alcohol, adipic acid) and heat treatment $(40^{\circ}C,\;60^{\circ}C)$ for the prolongation of shelf-life on low-salt Kimchi. Low-salt Kimchi was prepared with salt replacements (NaCl 50%, KCl 36%, $MgSO_4$ 10%, $CaSO_4$ 3%, glutamic acid 0.2%). Chemical characteristics and microbiological parameters were monitored during fermentation at $20^{\circ}C$. When three kinds of preservative which were alcohol 2.0%, adipic acid 0.1% and their mixture were added to low-salt Kimchi, shelf-life of them were prolonged. To extend the shelf-life of low-salt Kimchi, when the heat treatment at $40^{\circ}C$ and $60^{\circ}C$ were tried, heat treatment at $60^{\circ}C$ was superior than at $40^{\circ}C$. In sensory evaluation of low-salt Kimchi, the control was showed the best quality in the overall acceptability. And low-salt Kimchi treated at $40^{\circ}C$ showed the most similar characteristics to the control Kimchi.

Objectives : Dementia has rapidly increased with the prolongation of life expectancy and aging in Korea. This study was conducted to estimate the prevalence of, and find related factors for, dementia in an urban elderly population, using a newly developed screening method. Methods : Seven hundred and six people, aged over 65 years-old, in Dong district of Gwangju, Korea, were recruited using stratified cluster sampling, and completed Korean version of Geriatric Mental State Schedule B3 (GMS B3-K), the Korean version of the Community Screening Interview for Dementia (CSID-K) and modified 10 word list-learning from the Consortium to Establish a Registry of Alzheimer's Disease (CERAD). Dementia was diagnosed by an algorithm derived from all three of these measures. Results : The crude and age adjusted prevalence rates of dementia were 13.0 and 11.5%, respectively. Age, education, marital status and a history of cerebrovascular disease were identified as factors related with dementia. Conclusions : The new instrument, using the GMS B3-K, CSID-K and modified 10 word list-learning from the CERAD, was considered effective as a community screening and diagnostic tool for dementia. The results of this study can also be used to develop a community-based prevention and management system for dementia in the future.

Two Antihistamines, terfenadine and astemizole have been withdrawn from major markets for the reason that these durgs have been reported to induce QT interval prolongation associated with the onset of Torsades do Pointes (TdP), resulting in a life-threatening ventricular arrhythmia. In this study, we investigated effects of diphenhydramine on electrocardiograms and hemodynamic parameters in conscious telemetered dogs. We validated and defined the sensitivity of the test system by monitoring basal parameters and using positive control substance, terfenadine. Single administration effects were tested during 24 hours for each test drug at dose 1 mg/kg, 10 mg/kg, 30 mg/kg, 100 mg/kg. We monitored QT, QTc, heart rate, blood pressure and body temperature after administering test drugs. In conscious telemetered dogs, diphenhydramine significantly prolonged $QT\;(6.8\%\;of\;basal)\;and\;QTc\;(7.8\%\;of\;basal)$ at 100 mg/kg. Other parameters were not affected significantly. These findings suggest that antihistamines could induce important clinical relevance for patients taking excessive dosages of conventional antihistamines and those at risk of developing cardiac arrhythmias. Future studies that include other antihistamines and other classes will be necessary to predict the torsadogenic risk of drugs in humans.

Precooling and improved packing of mushrooms were investigated with a view to prolonging their freshness. Harvested mushrooms were precooled by forced air cooling and then packed in an EPS container. Mushrooms were transported to customers by insulated truck and stored at either $10^{\circ}C\;or\;25^{\circ}C$. Conventionally packed mushrooms in cartons were also examined as controls. Mushroom respiration rate slowly fell 2- to 3-fold upon precooling. Weight loss was decreased by precooling and the use of the insulated pack. Also, the L-value of the mushroom surface remained high with precooling, and mushroom elongation was less than in the control. Summer market life was extended to 3-4 days (from 1-2 days) by the improved distribution method.

Objectives: The purpose of this study is reporting the possibility of the treatment of metastatic brain tumors with allergen removed Rhus verniciflua Stokes (aRVS) after gamma knife radiosurgery. Methods: A patient with lung cancer felt a headache about one year after conventional therapies, and metastatic brain tumors were diagnosed. He received gamma knife radiosurgery twice but refused to get more conventional therapies afterwards. So he has been treating with aRVS since then. Results: During 143 weeks of administration of aRVS, the size of brain masses has decreased continuously without extracranial metastasis and the patient has maintained a good performance status. Conclusions: This report suggests that aRVS may play a therapeutic role in the treatment of metastatic brain tumors. Further studies will be needed to determine the effect of aRVS on metastatic brain tumors.

Osteoporosis is a rising problem, as the older age population is increasing due to prolongation of life. Genetic and environmental factors play key roles in bone metabolism, and diet is also an important factor. We investigated the relationship among factors affecting bone mineral density (BMD), including daily food intake and nutrient intake in men aged >50 years. Seventy-eight men, who visited the health promotion center at one of the university medical centers, were divided into normal and osteopenia groups according to their BMD. The body weight of the normal group was significantly higher than that of the osteopenia group. The osteopenia group showed significantly higher carbohydrate intake and lower calcium and vegetable calcium intake compared to those in the normal group. Lumbar spine BMD was negatively correlated with energy, fat, vitamin B1, and sodium intake in the normal group. Additionally, femoral neck BMD was negatively correlated with total animal protein, energy, protein, fat, phosphorous, iron, animal iron, potassium, vitamin B1, B2, B6, and niacin intake. Lumbar spine BMD was positively correlated with fruit, calcium, vegetable calcium, animal calcium, and vitamin C intake in the osteopenia group. Femoral neck BMD was negatively correlated with meat, dairy product, total animal protein, plant protein, animal protein, vitamin A, and cholesterol intake. A stepwise multiple regression analysis revealed that several dietary factors affected BMD, including energy, fat, vitamin B1, B2, B6, niacin, sodium, protein, iron, animal iron, phosphorous, potassium, and animal protein in the normal group and zinc, calcium, vegetable calcium, animal calcium, vitamin C, fruit, protein, animal protein, meat, dairy product, carbohydrates, cholesterol, vegetables, mushrooms, and seasonings in the osteopenia group. These results indicate that adequate nutrient intake plays an important role maintaining optimum bone health in middle aged men.

The health benefits of friendly bacteria first came to the attention of the general public in 1908, when Dr. Elie Metchnikoff, a Russian biologist, wrote The Prolongation of Life. The longevity may be, in part, due to the antioxidative ability of lactic acid bacteria. However, the antioxidative effect of lactic acid bacteria has been reported only recently. Many kinds of reactive oxygen species can be formed in the human body and in food system, oxidative stress plays a significant pathological role in human disease. Antioxidants are effective for the reduction of oxidation induced by oxygen radicals by scavenging reactive oxygen species. Various synthetic and natural antioxidants have been reported, but there are doubts about the safety and long term effects on health. Antioxidants from natural sources are likely to be found more desirable. An elevated scavenging ability of reactive oxygen species would be a good property for commercially applied lactic acid bacteria. Antioxidant supplement or food containing antioxidants would be greatly applied for the reduction of oxidative damage for human body, and lactic acid bacteria are potentiated candidates for the production of functional foods or natural antioxidant supplements.
