This study was carried out to investigate the intake patterns of health food according to the kind of disease of the elderly aged over 60 years living in the Chuncheon area. This study was conducted by using a questionnaire from December 1999 to the March 2000. The data was analyzed using a SPSS program. The results were summarized as follows : The poorer the self- perceived health condition, the lower the level of activity of daily living(ADL) and instrumental activities of daily living(IADL) were the higher. the frequency score of health food intake. The incidence of disease, such as arthritis(44.7%), hypertension(18.8%), digestive diseases(17.1%), diabetes(10.5%) were found to be higher. than other chronic diseases among the elderly. The frequency score of health food intake was not significantly different according to self-perceived health status, disease status, or the level of ADL and IADl.. The must important source of information for health food intake was the recommendation of friends and relatives(68.7%). Twenty eight point two percent of the elderly considered health foods to be effective, however 8.3% of the elderly considered them to be ineffective. The elderly with chronic diseases had taken health floods in the descending order of neuralgia-arthritis, hypertension, digestive disease, diabetes. The elderly with digestive diseases, diabetes, renal disease, neuralgia- arthritis and respiratory disease were inclined to habitually take health floods once or twice per year. Intake of Korean traditional folk food was as high as intake of registered health food and Chinese tonic medicine. The most frequently taken health food was tonic medicine, which is fo11owed by pumpkin, ginseng products, herbal tea formula with black goat, deer antler and Kye-so-ju. Intakes of health food such as tonic medicine, blood of the deer, royal jelly, aloe were found to be higher among the elderly with chronic diseases such as diabetes, hypertension, and digestive disease. However, intakes of ginseng products, deer antler, pumpkin, herbal tea formula with black goat and Kye-so-ju were found to be higher among the healthy elderly. The elderly with neuralgia-arthritis had taken sixteen kinds of health foods. From these results, a wide consumer education program should be developed to convince people of the importance of well-balanced diet and to choose proper health foods according to the elderly's health conditions. Also, comprehensive and scientific research into Korean traditional folk foods are needed for the correct use.

This study inferred the ecology of habitat use of the wild boars (Sus scrofa) in Yeongwol Hanbando wetland through DNA analysis using non-invasive samples of hairs. From November 2018 to May 2019, hair samples were collected from rubbing trees and hairtraps within the Hanbando wetland (2.772 ㎢). We extracted DNA from the hair samples and conducted PCR to verify the species and identify sex of the individuals. In addition we analysed 6 microsatellite markers to identify individuals and genetic relationship among the pairs of individuals. A total of 16 boar hairs were sampled, which turned out to be from 10 individual (7 females and 3 males) boars. We found that 9 pairs, out of 45 possible pairs, were most likely to be relatives. The result from kinship data and the location of the sampled hairs suggest that wild boars in this area live as family groups that consist of a mother and her offspring, which is consistent with known habits of wild boars. It is needed to include more samples and microsatellite markers for better precise estimation of kinship among the boar individuals.

The current traffic accident reduction procedure in economic feasibility study does not consider the characteristics of road and V/C ratio. For solving this problem, this paper suggests methods to be able to evaluate safety of each road in construction and improvement through developing accident Prediction model in reflecting V/C ratio Per road types and traffic characters. In this paper as primary process, model is made by tke object of urban roads. Most of all, factor effecting on accident relying on road types is selected. At this point, selecting criteria chooses data obtained from road planning procedure, traffic volume, existence or non-existence of median barrier, and the number of crossing point, of connecting road. and of traffic signals. As a result of analyzing between each factor and accident. all appear to have relatives at a significant level of statistics. In this research, models are classified as 4-categorized classes according to roads and V/C ratio and each of models draws accident predicting model through Poisson regression along with verifying real situation data. The results of verifying models come out relatively satisfactory estimation against real traffic data. In this paper, traffic accident prediction is possible caused by road's physical characters by developing accident predicting model per road types resulted in V/C ratio and this result is inferred to be used on predicting accident cost when road construction and improvement are performed. Because data using this paper are limited in only province of Jeollabuk-Do, this paper has a limitation of revealing standards of all regions (nation).

Vegetation composition and structure of forest community around Mt. Kumbong, Uiseong-Gun, Korea, were studied using a qualitative and a quantitative approach. Vegetation types and various ecological characteristics including constancy classes, relative coverage, species diversity and interspecific similarity of the major component species were analyzed. Seventy relatives were sampled in $100 m^2$ plots. Forest communities were grouped into mountain vegetation and lower-valley vegetation. The former were divided into 3 communities (Quercus mongolica, Quercus variabilis and Quercus dentata communities). The latter was an Acer mono community. Vegetation units were classified into ten groups. Woody vegetation coverage was $50\~65\%$. The lower-valley vegetation type showed from $2.06\pm0.25\;to\;2.31\pm0.26$ in the species diversity. The species showing interspecific similarity over 0.5 with Quercus mongolica appeared to be Pinus densiflora, Quercus dentata and Tilia amurensis in the tree and subtree layer, and Lindera obtusiloba, Fraxinus sieboldiana, Carex humilis and Carex siderostica in the shrub and herb layer, The species showing higher interspecific similarity with Acer mono were Cornus controversa and Ulmus davidiana in the tree and subtree layer, and Philadelphus schrenchkii and Aristolochia manshuriensis in the shrub and herb layer.

This study investigated differences or similarities of infant rearing practices in Korea, Hong Kong and the United States and in young mothers and grandmothers generations. The silbjects were young mothers(YM) with babies from 2 to 2.5 years and their mothers or mothers-in-law(GM) in Korea(YM=118, GM=118), Hong Kong(YM= 126, GM=78) and the United States(YM= 105, GM= 105). The subjects answered questionnaires on infant rearing practices that were constructed by child study specialists in Korea, Hong Kong and the United States. Statistical analyses were by frequencies, percentages, and $\chi$$^2$ The results of this study were as follows. 1. Kum-Jut was used to announce giving birth to relatives and neighbors only in Korea. Mothers in Korea were more helped in their recovery by their mother or mother-in-law than their husband, but the opposite was the case in Hong Kong and the United States. Most Korean mothers ate special foods after giving birth, but mothers in Hong Kong and the United Slates didn't. Mothers in Korea were more likely to avoid contact with strangers for a given period of time than mothers in Hong Kong and the United States. The babies in Korea were more often named by grandparents than by parents, but most of the babies in Hong Kong and the United States were named by parents. The greater part of babies in Korea didn't have childhood names or nick names, but most babies in Hong Kong and the United States did. 2. Mothers in Korea were more likely to give a banquet, exercise Dol Jab le, share foods with neighbors, and take souvenir pictures on the baby's first birthday than mothers did in Hong Kong and the United States. Most mothers in Korea tended to think that their baby's fiyst birthday was more meaningful than the other birihdays, but most mothers in Hong Kong and the United States didn't. 3. Some differences between young mothers and grandmothers generations in infant rearing practices were found in each culture.

The purpose of this study is to determine the clinical nurses' knowledge of DM and diabetes patient education aptitude so as to provide a basis for clinical nurse training with respect to diabetes patient education program. The data has been collected through the questionnaires of 42 items from the Knowledge on DM and each 16 item from the Importance on the elements of diabetes patient and the Recognition for clinical nurses, respectfully. 166 nurses from a general hospital who had participated in clinical nurse training in Sep. 28 and Oct. 4, 2001 were subject to respond the questionnaires. Analysis has been done by using statistical method such as percentage, average, standard deviation, t-test, ANOVA, Duncan test and Pearson correlation coefficients. The findings are as follows: 1. Clinical nurses' knowledge levels of diabetes 1) The average level of nurses' knowledge about diabetes is 29.37 (right answer- finding rate: 70%), which is intermediate. 2) Amongst the nurses classified by their knowledge levels about diabetes, the group with less than one year career and that with more than 5 year careers are found to have higher knowledge levels. The item with the highest right answer-finding rate was 'Please find the wrong out of the following examples about foot care'. Meanwhile, the item with highest incorrect answer-finding rate was 'what does blood sugar control aims for amongst gestational diabetes?'. 2. Clinical nurses' importance and perception levels of educational training about diabetes 1) There were no differences amongst nurses' importance level about diabetes. 2) Nurses usually had high scores(4.30) in terms of the items related to the importances about educational training. 3) There were quite high recognitions of general characteristics and symptoms about diabetes, amongst the nurse cohorts working more than one year and less than 5 years, and over 5 years, the group belonging to the internal department, that having the previous experiences of dealing with diabetes, and that having their diabetic relatives and other close people. Meanwhile, strangely, the group who identified themselves as 'not good at treating diabetes' had a high recognition level of educational training about diabetes. 3. Relationship between knowledge levels and importance & perception levels of diabetes 1) The higher knowledge about diabetes nurses had, the more importance they recognized. 2) It is found that there was no relationship between knowledge and perception of diabetes. 3) The more importance about diabetes nurses had, the higher perception they obtained. In conclusion, there is an urgent need for systematic educational programs about diabetes including technical aspects, in order to upgrade and improve nurses knowledge levels. In addition, re-educational training should be provided at regular intervals. Further, we believe the nurses with high knowledge about diabetes and interests in the provision of educations for patients can be far more confident, and in return, patients can have better self-management about diabetes obtained through educations. Based on the above-mentioned findings, we would like to make the suggestion: re-evaluation about nurses' knowledge and cognition levels should be carried out after job training programs about diabetes.

Married women who follow occupations have remarkably increased. Economic-activies married women[EAMW] have experienced a great degree of role confilcts as the results of that they should play the role of wage workers and do duty as household affairs as well as raise children. To understand problems of EAMW and to make alterniative plans for EAMW, the daily life actives of EAMW should be examined. This study attempts to understand the daily life activites of EAMW. To obtain the goal this research generalizes the daily life actives of EAMW. classifies the patterns the activites, and analyzes the activites in the micro-level. The acivites of EAMW mainly consist of formal business and household affairs. The spatial bounds of activities are influenced by weekdays and holidays. During the weekday their activities are mainly found around residences and/or work places; while, during the weekend, they are discovered around residences and/or around residences or relatives who take care of their children. EAMW move longer distance rather than a full-time housewife; however, the activites of EAMW are residential orientation like those of full-time housewives. The role conflicts of EAMW are mainly from social cultural structure, the distance between workplace and residence, and the location of public service institutes.

For the identification of the Jeju black cattle, Hanwoo and imported beef, we performed a multiplex polymerase chain reaction (PCR) associated with microsatellite (MS) and melanocortin 1 receptor (MC1R) gene. The MC1R gene plays an important role in regulation of the melanin synthesis within mammalian melanocytes. MC1R encoded by extension (E) locus was almost fixed with recessive red e allele in the Hanwoo. We estimated that the specific genotypes ($E^+/E^+$, $E^+/e$) of MC1R gene were characteristic genotypes of Jeju black cattle. But the PCR products resulted from using the MC1R gene derived primers only are not sufficient to identify Jeju black cattle from other relatives. We performed two times of successive multiplex PCR to provide a more accurate result for the identification of Jeju black cattle. The results suggest that two types of successive multiplex PCR methods using MC1R gene and Microsatellite derived primer set will be more useful to identification of Jeju black cattle, Hanwoo and imported beef.

This study examined the satisfaction of the married women from aged 20s through 50s with well-being oriented foods, considering the importance of each subordinate field and verifying the differences between the groups according to socio-demographic factors, purchase behavior factors, and well-being oriented dietary life factors, followed by an analysis of the relative influence of those relevant factors. A preliminary survey was conducted from January 4th-11th, 2009 to check if there were any problems or misunderstood parts before the main survey. After the preliminary study was conducted, certain problems were adjusted and supplemented, and then the main survey was conducted for twenty-three days, from January 4th to February 5th, 2009. The summaries of this study are as follows: First, in the view of the purchase behavior, the mainly purchased well-being oriented foods were farm products, and the leading purpose of the purchase was for the parents and the children. It was shown that 30% or more of the information sources on well-being oriented foods were families, relatives and neighbors. More than 66% of the purchasing was done at wholesale marts and the topped purchasing frequency was from 5 to 6 per month. More than 71% of payments for well-being oriented foods were \50,000~100,000 per month. More than 51% of the respondents answered that the proper price of well-being oriented foods was 1.2 times to 1.5 times of that of other foods. Second, the satisfaction of the well-being oriented foods was ranked as 3.21 to 3.28 out of 5, and varied with the usages and the methods of weights. Investigating the satisfaction with each subordinate field, the satisfaction with price was shown to be low. The satisfaction with the assortments of foods and the satisfaction with the therapeutic degree by thorough investigation and management of foods were also relatively low. Third, well-being oriented dietary behavior was shown to be characterized by two factors, through factor analysis in this study. One was an eco-friendly oriented behavioral factor and the other was a health oriented selective factor. Fourth, the stepwise multiple regression analysis results investigating the relative influence of the factors effecting satisfaction with well-being oriented foods showed that the top ranked factor affecting total satisfaction was eco-friendly oriented behavioral factor, followed by education level and purchasing sites, especially of consumer groups.

Proteolytic bacteria were isolated from Myeolchi-jeotgal and Saeu-jeotgal using high-salt-content media and their growths in the media containing 25% NaCl were monitored to draw the role of bacteria in the ripening of jeotgal. The most populous genus in Myeolchi-jeotgal detected on agar media with 15% NaCl was Bacillus and its relatives, while the most populous in Saeu-jeotgal was Staphylococcus. Among the isolates, Virgibacillus halodenitrificans from Myeolchi-jeotgal and Halobacillus trueperi from Saeu-jeotgal showed proteinase activities. The species from Myeolchi-jeotgal showed proteinase activity on the agar media with 8% NaCl were similar to those isolated from the media with 15% NaCl. The dominant of Myeolchi-jeotgal isolated at the 15% NaCl concentration may be involved in the proteolysis. The proteolytic species from Saeu-jeotgal on the agar media with 8% NaCl were the genera Bacillus, Salinicoccus, and Salimicrobium those were not the dominants at 15% NaCl condition. The dominant isolates from Saeu-jeotgal on agar media with 15% NaCl may not be involved in the proteolysis of Saeu-jeotgal. Vb. halodenitrificans and Staphylococcus equorum, the dominant species from Myeolchi-jeotgal and Saeu-jeotgal, showed growths at the nutrient broth containing 25% NaCl. They may play a significant role in the ripening of jeotgal and have a high possibility to be used as the starter.
