Meal menus were developed and applied for rural elderly of Gangwon and Chungnam areas at agricultural off-season. Amounts of the major nutrients of carbohydrate, protein, lipid, and calorie considered in the menu based on the dietary reference intakes(DRI) of the elderly aged over 65 years were 97.5g, 22.5g, 13.3g, and 600kcal, respectively. In Chungnam, softness and overall acceptance of rice in menu 4, consisted of cereals and rice, kimchi stew with tuna, pan-fried bulgogi mushroom, seasoned dropwort carrot, kimchi, and banana, scored the highest values of 8.5 out of 9.0point hedonic scale (p<0.05). In Gangwon, soup and side dish of menu 3 (rice, frozen pollack pot stew, meatball fried in egg, seasoned sea lettuce, and banana) scored significantly the highest of all (p<0.05). Overall acceptance of all the menus were high over 7.8 without significance in Chungnam. Overall acceptance of the menu 3 scored significantly the highest with value of 8.5 and menu 4 (rice, spicy chicken soup, seasoned bean sprouts, broiled brown seaweed trunk, kimchi, tomato) had significantly the lowest value with value of 7.8 in Gangwon(p<0.05). The total leftover volume of menu 4 was significantly the highest with score of 56g and the menu 4 showed the highest unit cost of 2,900won in Chungnam. However, the total leftover volume of all menus did not show significance ranging from 9g to 19g in Gangwon.

This study was conducted to find out the optimum container for increasing acclimatization rate of in vitro mass propagated plantlets of Ever-bearing strawberry (Fragaria ${\times}$ ananassa Duch.) via bioreactor. Four types of containers were used such as transparent plastic container (TPC), plug tray (PT), I-pot (IP), and black vinyl pot (BVP). Number of date maintaining soil water content above 10% was five days in TPC, three to four days in BVP, two days in PT, and one day in IP. Survival rate of plantlets was 80% in BVP, 70% in TPC, 55% in IP, and 15% in PT. In TPC, growth increment of plantlets was the greatest among all the tested containers and the lowest in IP. Numbers of runner per plant were 3.3 in BVP, 2.9 in TPC, 1.6 in PT, and 1.2 in IP. Total cost was 44,405,300 won/10 a in BVP, resulting in reducing more 6,659,400 won/10 a than IP's (51,064,700 won/10 a). Around 102,718 plants/10 a were produced by using BVP, suggesting that 30,265.1 plants/10 a more could be produced than IP (72,452.9 plants/10 a). Production cost per plant was 432.3 won in BVP, resulting in reducing 272.5 won than IP's (704.8 won). As a result, BVP was appropriate for acclimatization of in vitro plantlets through bioreactor system.

This study was conducted to identify the problems in the medical aid program by reviewing the medical care utilization pattern of the beneficiaries. The data were abstracted from the monthly bills and vouchers for medical care of the whole benefi챠aries(17,527) in Gyeongsan Gun submitted by the physicians to county government for the period of 1 calendar year from October 1981 to September 1982. The number of medical aid beneficiary accounted for 12.7% of the total county population, a higher proportion than the national average-9.5%. Monthly primary care utilization rate per 100 beneficiaries was 9.3 persons with 14.0 visits and 42.9 medication days. for the 2nd and 3rd care, there were 1.7 admissions and 9.3 OPD visits per 100 beneficiaries per year. The beneficiaries of the first class medical aid program had a higher utilization rate of both the primary and secondary/tertiary care facilities. Females utilized more the primary care facilities than males while males utilized more the secondary/tertiary care facilities than females. A significantly lower utilization rate was observed in January than in the other months and this was seemed due to the renewal process of the medical aid certificate. Among 1,931 patients utilized the 2nd/3rd care facilities 84.4% was out-patients and the lowest ratios were in the minor specialties including ENT, ophthalmology, dermatology and urology. The average hospital days per in-patient were 21.2 days and OPD days per out patient were 4.7 days. The average hospital days for a psychiatry in-patient was 74.4 days which was the longest average hospital days among all the specialties. Average medical care cost per beneficiary in a year was W9,821:W24,240 for the 1st class and W7,464 for the 2nd class. The medical care cost for the primary care per patient was W3.901 and W840 per day compared with W49,875 per patient and W5,822 per day for the secondary/tertiary care. From the findings of this study following recommendations were made to improve the medical care program: 1) The renewal process of the medical care certificate should be expedited. 2) Minor specialty clinics should be designated as the primary medical care facility for the medical aid program to reduce the expenses by absorbing more patients referred to the secondary/tertiary care facilities directly. 3) The medical care cost for the primary care facility should be escalated to reduce the differential between the primary and secondary/tertiary care facilities.

Since mine wastes were merely dumped in the mine waste dump, they have produced acid mine drainage (AMD). Therefore, main objective of this study was to evaluate the effect of coal combustion products (CCPs) on heavy metal stabilization and detoxification for mine wastes. Total six treatments for incubation test were conducted depending on mixing method (completely mixing and layered). Also, lysimeter experiment was conducted to examine efficiency of polyacrylamide (PAM) on reduction of mine wastes erosion. Result of incubation test showed that concentrations of soluble aluminium (Al) and iron (Fe) in leachate decreased compared to control. The lowest soluble Al and Fe in leachate was observed in 50% mixed treatment (14.2 and $1.03mg\;kg^{-1}$ for Al and Fe respectively) compared to control treatment (253.0 for Al and $52.6mg\;kg^{-1}$ for Fe). The pH of mine wastes (MW) and leachate increased compared to control after mixing with CCPs and ordered as control (MW 6.4, leachate 6.3) < 10% (MW 7.7, leachate 7.1) < 20% (MW 9.0, leachate 7.8) < 30% (MW 9.5, leachate 8.3) < 40% (MW 9.9, leachate 8.5) < 50% (MW 10.5, leachate 8.6). Application of PAM, both in liquid and granular type, dramatically decreased the suspended solid (SS) concentration of CCPs treatments. Reduction of SS loss was ordered as MW70CR30L ($24.4mg\;L^{-1}$) > MW70CR30LPL ($6.7mg\;L^{-1}$) > NT ($3.1mg\;L^{-1}$) > MW70CR30M ($1.6mg\;L^{-1}$) > MW70CR30MPL ($1.1mg\;L^{-1}$) > MW70CR30PGM ($0.7mg\;L^{-1}$) > MW70CR30LPG ($0.5mg\;L^{-1}$) > MW70CR30MPG ($0.4mg\;L^{-1}$). Overall, application of CCPs can be environmental friendly and cost-effective way to remediate coal mine wastes contaminated with heavy metals. In addition, use of PAM could help to prevent the erosion coal mine wastes in mine waste disposal area.

This study was conducted to estimate the effect of dietary alfalfa meal on the contents of egg yolk cholesterol, the levels of egg yolk pigmentation and the performance of laying hens. Alfalfa meal which was alternated wheat bran was supplied 0, 3.5 and 7%, respectively. Total 192 brown laying pullets of 47 weeks old were randomly assigned to the wire cages from July 23 to October 7, 1991 for 10 weeks. The results obtained were summarized as follows ： 1. The egg production was highest at 3.5% alfalfa meal level during the entire period. But there was no significant difference among treatments. 2. Egg weight increased in treatments 3.5 and 7% alfalfa meal supplementation significantly. (P<0.01). 3. Even though there was no significant difference, the daily egg mass was the highest at 3.5% of alfalfa meal level. 4. Daily feed intake was the highest at 3.5% of alfalfa meal level. However, feed conversion rate was the lowest among treatments. 5. The feed cost per kg egg mass in the treatment of 3.5% alfalfa meal was significantly lower than the other treatments. (P<0.05). 6. Shell thickness and shell weight in terms of egg shell quality were increased as the levels of alfalfa meal were increased. But there was no significant difference among treatments. 7, The egg yolk Pigmentation was improved significantly as the level of alfalfa meal was increased (P<0.01). 8.899 yolk cholesterol contents were decreased in the treatments of 3.5 and 7% alfalfa meal supplementation compared with those in the treatment of wheat bran only(P >0.05). The results of this study indicate that 3.5% alfalfa meal level was most effective and economical in laying hen.

To find out the actual status of treatment of physically handicapped who were stayed of home, 320 physically handicapped persons were selected among total 6,264 physically handicapped registered in Taejon city, surveyed from January 1st to March 30, 1997. Following are the results ana lysed of collected data from 201 samped persons. 1. For the cause of physically handicapped, 36.3% was congenital, 26.9% was cerebralvascular acciednt(CVA). and 14.9% was infectious diseases and others in that orders. The must frequest cause of below 20 years age group was congenital cause, but that of $20{\sim}30$ years age group and $40{\sim}50$ years age group were accident and CVA repectively. 30.0% of respondents caused by infection and others earned household living expenses. Household living expenses were higher among the respondents caused by congenital cause but those were lowest in the accidental couse group. Handicap durations were longer in the accidental cause group and infections and others group than the congenital cause group and CVA group. 2. 54.7% of studied handicapped were under treatment. But 36.3% of them were stopped treatment, and 8.9 % of them answered not treated. Most handicapped, coused by congenital and CAV, were under treatment, but most of them caused by accidental and others were stopped treatment. 3. For the medical facilities, 54.5% of them utilized welfare facility, but 25.5% utilized general hospital and 20.0% of them utilized oriental medical hospital and health centers. Congenital cause group frequently selected welfare facility for the treatment facility. But accidental cause group frequently seleced general hospitals and CVA gruop frequently selected oriental medical hospital and others. The medical cost of welfare facility, oriental medical hospitals and others were lower than that of general hospitals. 4. The proportions of under treatment were higher among yonger age higher monthly living expenses group shorter handicapped duration groups, congenital cause group and handicap grade II group. But that of stop treatment were higher among congenital cause group, infectious and others cause group, and handicap grade I & then III group. 5. For the feelings satisfacion about medical treatment, only 35.3% of under treated group responed satisfation. 55.5% of them responded so-so, but 9.1 % responed dissatisfaction. The proportion of satisfaction was higher among shorter handicap duration group.

This study investigates the differences among residental areas in the health, standard of living, and social relationships of female elderly living alone. The total of 501 subjects(185 from rural areas, 159 from fishing communities, 77 from the islands, and 80 from urban areas) were questioned from May to July, 2006. The research area was confined to Chungcheong Province. The female elderly living alone of this study were an average of seventy-three years old, had a low cost of living, and received little formal school education. Over sixty percent(60.3) of them lived on less than thirty dollars a month which was the recognized Korean poverty level in 2006. The female elderly living alone were evaluated as being in good health, but they themselves perceived their health as being poor. Observed by residential areas, the subjects in urban areas were lower in ADL, and both the urban dwellers and the islanders appeared to be higher in their satisfaction with medical services as compared to those in rural areas and fishing communities. The fishing villagers showed the lowest standard of living for female elderly living alone. The analysis of social relationships as seen in the different residental areas revealed that the female elderly living alone g in urban areas tended to be receiving social supports rather than providing for others, and subjects living in fishing areas and the islands proved to be relatively higher in the exchange of social supports. In relation to offspring, the female elderly living alone in urban areas had a lower frequency of meeting with their children and also a lesser degree of intimacy with them because they lived at a distance. On the other hand, subjects living in rural areas and fishing communities had a higher frequency of meeting with their children and a greater degree of intimacy with them even if they lived at a distance. The study also showed that the female elderly living alone in the islands had a higher frequency of once meeting per three week with their offspring and a higher degree of intimacy with them because they all live in the same islands. In conclusion, the subject living in urban areas appeared to be isolated from their offspring as compared to the other seniors in the study. The female elderly living alone in urban areas suffered from an insufficient network of relatives and neighbors, and they experienced a poor quality of relationships to their offspring. Almost all of the lone seniors in the study had a low score in social activities; however, the female elderly living alone in urban areas revealed a higher level of participation in volunteer activities, group activities, and educational activities. Nevertheless, the lone seniors living in urban areas were not satisfied with their participation in social activities. The subjects living in rural in fishing communities and the islands showed more participation in money-making activities. This study suggests that the policies for female elderly living alone should reflect the differences of regional characteristics.

Purpose: The purpose of this study was to evaluate the diagnostic accuracy of X-rays in patients with acute traumatic vertebral fractures visiting the emergency department and to analyze the diagnostic value of X-rays for each spine level. Methods: We retrospectively analyzed basal characteristics by reviewing medical records of 363 patients with adult traumatic vertebral fractures, admitted to the emergency center from March 1, 2014 to February 28, 2017. We analyzed spine X-rays and magnetic resonance imaging (MRI) scans to determine distribution according to the vertebral level, and we evaluated the efficacy of X-rays by comparing discrepancies between X-rays and MRI scans. Results: For a total of 363 patients, the mean age was 56.65 (20-93) and 214 (59%) were males. On the basis of X-rays, 67 cases (15.1%) were of the cervical spine, 133 cases (30.0%) were of the thoracic spine, and 243 cases (54.9%) were of the lumbar spine. In particular, the thoracolumbar region (T11-L2) was the most common, with 260 cases (58.7%). In X-rays, fractures were the least in the upper thoracic region (T1-T3), whereas MRI scans revealed fairly uniform distribution across the thoracic spine. Sensitivity of X-rays was lowest in the upper thoracic spine and specificity was almost always greater than 98%, except for 94.7% in L1. Positive predictive value was lower in the mid-thoracic region (T4-T9) and negative predictive value was slightly lower in C6, T2, and T3 than at other sites. Diagnostic accuracy of X-rays by vertebral body, transverse process, and spinous process according to fractured vertebral structures was significantly different according to vertebral level. Conclusions: Diagnostic accuracy of X-rays was lower in the upper thoracic region than in other parts. Further studies are needed to identify better methods for diagnosis considering cost and neurological prognosis.

This exploratory research investigated the factors that influence foreign tourists' decision to use dental services in Thailand. The questionnaire was used to collect data from foreign tourists who used dental services in a hospital or dental clinic in Thailand. Data from 233 respondents completed questionnaires were analyzed using frequency distribution, percentages, mean, and standard deviation. The findings revealed that respondents were most likely to be Asian (54.5%) followed by European (33.9%), females (64.8%) aged between 26-35 years (39.1%), business owners (45.9%), and came to Thailand with friends (47.6%). Regarding travel purposes and contact with dental services, most of them travel for pleasure (52.89%) and contact the clinic directly through the Internet(63.95%) The health/medical services used included health check-up (34.48%), dental services (29.22%), and day spa/massage (23.23%). The dental treatment that respondents had completed or planned to do included dental check-up (29.87%), tooth cleaning (26.68%), and tooth whitening (11.41%). Based on the influence of $_7P$ factors towards the respondent's decision to use the dental service, it was found that the average mean score range from 4.33-4.15 which were at the high to the very high level of influence to their decisions. The people factor had the highest average mean score (mean 4.33, SD= 0.604)followed by the price factor (mean 4.32, SD= 0.651), which both had the highest level of influence. The physical evidence factor had the lowest mean score (mean 4.15, SD+0.752) which was at the high level of importance. It should be noted that the factor concerning the modern technology and dental equipment (mean 4.33, SD=0.606) and factor on the quality of service (mean 4.43, SD= 0.598) had the highest mean score followed by the total cost of the trip including services being reasonable (mean 4.37, SD=0.582). Regarding the country factor, it was found that this factor also had highest influence level (mean 4.30, SD=0.67) and affordability had the highest mean score (mean 4.39, SD=0.614).

Objective: Substituting starch with digestible fiber (dF) can improve digestive health of rabbits and reduce costs. Therefore, it is necessary to develop a criterion for dF and starch supply. Effects of the dietary dF-to-starch ratio on pellet quality, growth and cecal microbiota of Angora rabbits were evaluated. Methods: Five isoenergetic and isoproteic diets with increasing dF/starch ratios (0.59, 0.66, 0.71, 1.05, and 1.44) were formulated. A total of 120 Angora rabbits with an average live weight of 2.19 kg were randomly divided into five groups with four replicates. At the end of 40 day feeding trial, cecal digesta were collected to analyse microbiota. Results: The results showed that the dF/starch ratio had linear effects on pellet variables (p<0.01). When the dF/starch ratio was 1.44, the pellets had the lowest powder and highest durability. The dF/starch ratio had unfavorable linear effects on growth variables (p<0.001). When analyzed by quadratic regression, the optimal dF/starch ratios for average weight gain and feed/gain were 0.59 and 0.74, respectively. There were differences in wool yield, fiber length and fiber diameter caused by the dF/starch ratio (p<0.05), and the dF/starch ratios that ranged from 0.66 to 1.06 were appropriate for good results. The cecal microbiota operational taxonomic unit (OTU) number index in the 1.05 dF/starch treatment was higher than that in the 0.66 and 0.71 dF/starch treatments. The higher dF/starch ratio resulted in a higher cecal microbiota OTU number index (p<0.05). The proportion of Ruminococcus in the 0.71 dF/starch treatment was higher than that in the 0.59 dF/starch treatment (p<0.05) Conclusion: The most suitable dF/starch ratio for feed pellet quality is 1.44, and for rabbit growth the optimal range of ratios is from 0.59 to 0.74. With combination of the wool growth, output cost, and cecal microbiota, we suggest that a dietary dF/starch ratio ranging from 0.74 to 1.06 is optimal.
