  • This study explored all domestic and international theories for maintenance and health enhancement of an old and big tree, and carried out the anatomical survey of the operation part of the tree toward he current status of domestic surgery and the perception survey of an expert group, and drew out following conclusion through the process of suggesting its reform plan. First, as a result of analyzing the correlation of the 67 subject trees with their ages, growth status. surroundings, it revealed that they were closely related to positional characteristic, damage size, whereas were little related to materials by fillers. Second, the size of the affected part was the most frequent at the bough sheared part under $0.09m^2$, and the hollow size by position(part) was the biggest at 'root + stem' starting from the behind of the main root and stem As a result of analyzing the correlation, the same result was elicited at the group with low correlation. Third, the problem was serious in charging the fillers (especially urethane) in the big hollow or exposed root produced at the behind of the root and stem part, or surface-processing it. The benefit by charging the hollow part was analyzed as not so much. Fourth, the surface-processing of fillers currently used (artificial bark) is mainly 'epoxy+woven fabric+cork', but it is not flexible, so it has brought forth problems of frequent cracks and cracked surface at the joint part with the treetextured part. Fifth, the correlation with the external status of the operated part was very high with the closeness, surface condition, formation of adhesive tissue and internal survey result. Sixth, the most influential thing on flushing by the wrong management of an old and big tree was banking, and a wrong pruning was the source of the ground part damage. In pruning a small bough can easily recover itself from its damage as its formation of adhesive tissue when it is cut by a standard method. Seventh, the parameters affecting the times of related business handling of an old and big tree are 'the need of the conscious reform of the manager and related business'. Eighth, a reform plan in an institutional aspect can include the arrangement of the law and organization of the old and big tree management and preservation at an institutional aspect. This study for preparing a reform plan through the status survey of the designated old and big tree, has a limit inducing a reform plan based on the status survey through individual research, and a weak point suggesting grounds by any statistical data. This can be complemented by subsequent studies.

  • Purpose: We performed this study to evaluate reliability on interpretation of three phase bone scintigraphy (TPBS) in patients with post-traumatic complex regional pain syndrome (PT-CRPS). Methods: Based on International Association for the Study of Pain guideline in 1994, 34 patients with PT-CRPS were selected for this study. Two nuclear medicine physicians evaluated identical TPBS according to the uptake pattern, extent and intensity of the lesion, and their agreements (kappa values) were analysed. The final diagnosis based on arbitrary criteria of each physician were compared with those obtained by the criteria for PT-CRPS established in this study, which are hyperactivity on all phases (criteria 1), hyperactivity of whole joints on delayed phase (criteria 2), and hyperactivity of either whole or FDGal joints on delayed phase (criteria 3). Results: Intra-observer agreements were good for uptake pattern, intensity, and extent on TPBS. Inter-observer agreements were also good, except extent on blood pool phase (0.55). The inter-observer agreements on final diagnosis improved when criteria 1-3 were applied (0.77-0.88), compared to when physician's own criteria were used (0.63). Those also improved from 0.29 to 0.47-0.82 for acute stage, and from 0.37 to 1.0 for chronic stage. The sensitivities of chronic stage were relatively lower to those of acute stage. Conclusions: Inter-observer's variations in diagnosis of the patients with PT-CRPS using TPBS were observed. These results were attributed to different criteria set by observers. In order to improve agreement on interpretation of TPBS, common positive criteria should be established, especially considering uptake pattern and clinical stages.

  • First, the average scores of personal financial management ability in the college students' financial management attitude were 72.24 for male and 71.65 for female, so that male students showed a little higher score than female. College students who had an experience of opening a bank account and who kept a record of spending revealed higher scores. Those whose parents were elementary or middle school graduates unfolded the highest score, 73.67, and the lowest score, 63.35, from those whose parents had M.A. or Ph.D. The average scores of personal financial management ability in the college students' financial management knowledge indicated almost no difference with 63.26 for male and 63.35 for female. Only whether they had an experience of opening a bank account, keeping a record of spending, or a credit card revealed score differences. Depending on the students' majors, there were also score differences. Students from engineering department came up with the highest score, an average of 66.88, and students from art & physical education department with the lowest score, 53.39, in the financial management knowledge. The personal financial management ability in the college students' financial management function showed that the score of male students was a little higher than that of female, 64.26 versus 63.58. Students who kept a record of spending and whose parents' income was between three million won and four million won marked the highest score, an average of 65.26, and students whose parents' income was below two million won marked the lowest score, an average of 60.43, in the college students' financial management function. There were score differences in the college students' financial management function depending on the students' majors. Students from engineering department came up with the highest score, an average of 69.67, and students from public health department with the lowest score, 63.21.

  • The radish skin and radish greens (mucheong) are an edible part of the radish. But they are removed before eating the radish and used as a byproduct or an animal feed material because of their tough and rough texture. This study was conducted to investigate the effect of supercritical heat-treated radish-extract on UV-induced Hos: HRM-2 wrinkled mouse animal model on anti-aging wrinkles. Supercritical heat-treated radish-extract was applied on the back of seven-weeks old HRM-2 mice. The effect of HRE on skin thickness, elasticity and wrinkle formation of the mice was observed by using UVB lamp to induce melanogenesis and wrinkle formation. As the result, increased depth of wrinkles was observed in the negative control group in comparison to the normal group. In contrast, decreased depth of wrinkles was observed in the radish-extract-free group compared to the negative control group. In the study of the effect of radish-extract on wrinkle-formation related gene expression and protein what protein expression, MMP-2 and MMP-2 gene expression significantly increased in the negative control group compared to the normal group. The gene expression reduced independence to the mass of radish-extract treated. Similar to quantitative results of mRNA expression, the expression of MMP-2 protein increased as a result of UVB-irradiation. The MMP-2 expression was inhibited in dependence to the mass of radish-extract treated. In conclusion, the supercritical heat-treated radish-extract has an effect on improving skin wrinkles not only when it is applied to the skin but also when orally ingested. Thus, it can be effectively used as a composition to health functional products. Thereafter, we can also conclude that radish, a food that does not show any side-effects even upon long-term intake, can reduce wrinkle formation as well as improve skin elasticity when taken regularly for a long period.

  • Background: Although pulmonary tuberculosis (TB) is a respiratory disease, the presence of Mycobacterium tuberculosis (Mtb) DNA or Mtb itself has been reported in the peripheral blood (PB) of several patients with pulmonary TB. Additionally, it was recently announced that active pulmonary TB patients donated PB, and that this blood was then transfused to other individuals in Korea. Methods: Sixty-nine patients with bacteriologically-confirmed pulmonary TB (35), non-tuberculous mycobacterial (NTM) lung disease (6), and other lung diseases (28) were enrolled in this study, which was conducted to determine if Mtb DNA could be detected in the PB by PCR. In addition, 10 pulmonary TB patients with high-burden bacilli were also enrolled in this study for the culture of Mtb in PB. Results: PCR detected the presence of Mtb in 22.8% (8/35) of the pulmonary TB patients, in 16.7% (1/6) of the patients with NTM lung disease, and in none of the patients with other diseases (0%). In addition, no Mtb was cultured from the PB of the 10 pulmonary TB patients. Conclusion: Although Mtb DNA was detected in the PB of some patients with pulmonary TB, viable Mtb was not isolated from the PB of those patients, which indicates that patients that viable Mth may not be transmitted via trasfusion of blood of pulmonary TB patients.

  • This study was carried out to evaluate the effect of vitamin $B_{6}$ intake by normal term delivery pregnant women on the concentration of vitamin $B_{6}$ in the material plasma, the umbilical cord plasma, and the placental tissue. Dietary intake data were obtained from a semi-quantitative frequency questionnaire. The daily mean energy and protein intakes were 2189.5 kcal (93.2% of RDA) and 79.3 g (113.3% of RDA), respectively. The average daily vitamin $B_{6}$ intake was 1.7 mg (91.4% of RDA) for the pregnant women. Their main sources of vitamin $B_{6}$ were cereal & starch (50%), and vegetables & fruits (33%). The pyridoxal phosphate (PLP) concentration of the maternal plasma, the umbilical cord plasma, and the placenta were 16.7 $\pm$ 4.1 nmol/1, 61.3 $\pm$ 19.8 nmol/l and 898.6 $\pm$ 159.2 ng/g, respectively. The PLP level was the highest in the placenta. The PLP level of the maternal plasma was significantly lower than the of the umbilical cord plasma (p < 0.001). The PLP level of maternal plasma correlated positively with that of the placenta (p < 0.0001) and the umbilical cord plasma (p < 0.05). Also the PLP level of the placenta correlated positively with that of the umbilical cord plasma (p < 0.05). These findings indicate that the vitamin $B_{6}$ nutritional status of the fetus is affected by placental vitamin $B_{6}$ levels, and that the placental vitamin B$_{6}$ levels reflect the maternal vitamin $B_{6}$ status. The umbilical cord plasma PLP level showed a positive correlation with the gestational length (p < 0.05). A negative association was observed between the PLP level showed of the umbilical cord plasma and the pregnancy weight gain (p < 0.03). The results suggest that the transfer of PLP from maternal plasma to the placental tissue could be an active transport, white the transfer of PLP from the placenta to the fetus is by means of simple diffusion. Thus, neonatal vitamin $B_{6}$ nutrition is influenced by the maternal nutritional status.

  • The purpose of this study was to compare the anthropometry, blood pressure, blood lipid levels, and nutrient intakes in three groups: a group with an impaired fasting blood glucose (IFG) condition (62 males and 30 females); a group with normal blood glucose (73 males and 50 females); and a group with diabetes mellitus (DM) (79 males and 49 females). In male subjects, body mass index (BMI) and obesity index values were significantly higher in the IFG group than in normal and DM groups, but waist/hip ratio (WHR), systolic blood pressure, and diastolic blood pressure were not significantly different from those of the DM group. In female subjects, there was no difference in body weight, BMI, obesity index and WHR values between the IFG and the DM groups. The prevalence of obesity in the IFG group (males 43.6%, females 76.7%) was the highest among the three groups. The percentage of high SBP (40.0%) and high DBP (52.0%) in male subjects of the IFG group was significantly greater than in the DM group or the normal group. In the male subjects, the serum triglyceride concentration was significantly higher in the DM group than in the normal and IFG groups. There was no difference in various nutrient intakes(energy, carbohydrate, protein, fat, calcium, iron, vitamin A and cholesterol) among the three groups. In male subjects, the percentage of energy intake from alcohol was higher in the IFG group (7.0%) than that of the normal (4.5%) and the DM (5.6%) groups. The fasting blood glucose level had a positive correlation with WHR, TG, the athrogenic index and LDL-cholesterol/HDL-cholesterol. This study suggested that the IFG group had a higher obesity index, BMI, blood pressure and serum lipid levels (TG, cholesterol) than the normal or the DM group; furthermore, the IFG group had higher levels of alcohol intake and habits of taking unbalanced diets. Therefore, guidelines for IFG group should emphasize weight control, diet therapy, physical activities and regular balanced diets, in order to prevent diabetes in this group.

  • Peroxisome proliferator activated receptor (PPAR)-$\alpha$ of three PPAR subtypes ($-\alpha,\;-\beta/-\gamma,\;-\delta$), which are members of the nuclear hormone receptor superfamily of ligand-activated transcription factors, plays a key role in lipoprotein and glucose homeostasis. A variation in the PPAR-a gene expression has been suggested to influence the development of metabolic syndrome through alterations in lipid concentrations. The aim of our study was to investigate the association between the PPAR-a and metabolic syndrome among South Korean. A total of 542 health screen examinees were enrolled in this study who were examined in Kosin University Gospel Hospital from December, 2004 to July, 2005. The height, weight, waist circumference, and systolic and diastolic blood pressure of the subjects were examined and fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride were measured by-sampling in venous blood. The metabolic syndrome was defined as the presence of three or more of the following : waist circumference men ${\geq}90cm$, women ${\geq}80cm$, blood pressure ${\geq}130/85mmHg$, fasting glucose ${\geq}110mg/dL$, HDL cholesterol men <40 mg/dL, women <50 mg/dL, triglyceride ${\geq}150mg/dL$. The blood pressure, fasting glucose, HDL cholesterol, triglyceride were evaluated by using the criteria of NECP ATP III and waist circumference was assessed by using the criteria of WHO Asia-Western Pacific. And the author compared the frequency of the PPAR-$\alpha$ mutation of L162V ($C{\rightarrow}G$ variant in exon 5) in a sample of 542 subjects with and without the metabolic syndrome by polymerase chain reaction allele-specific oligonucleotide (PCR-ASO) method. One (0.2%) hetero-isotype among high risk of metabolic syndrome was identified. The values of waist circumference, body mass index and low density lipoprotein cholesterol of the mutant were 100 cm, 28.6 $kg/m^2$ and 120 mg/dL, respectively. Although the author failed to see significant association between the presence of the PPAR-$\alpha$ L162V polymorphism and metabolic syndrome, one PPAR-$\alpha$ L162V polymorphism in metabolic syndrome patients was found.

  • The objective of this study was to investigate the current status of calcium fortification in processed foods for obtaining basic data on nutrition fortification policy and nutrition labeling, Surveyed samples were the products fortified wish calcium among processed products sold in department store and large mart in Seoul from Aug. 1998 to Aug. 1999. But supplementary health food or special nutritious food and weaning food and infant formula were excluded from them. We examined the kinds and numbers of added nutrients except calcium and the amounts of calcium per 100 g product and nutrient labeling of calcium-fortified foods. Surveyed products were 81 foods and they were grouped in grain products, milk and milk products, processed meat and fishes, ramyuns, retort pouch foods, fruit juice and drinks. and others. Calcium fortification was found in wide food groups, especially in snack foods and carbonated beverages. In relation to surveyed products, most of them were fortified with only calcium. The number of added nutrients in the product were relatively various in comparison with each food groups. In addition to calcium, the most frequently added nutrient was DHA, and were followed vitamin, mineral, oligosacchride, fiber, etc. This result showed that the kind(s) and the number(s) of nutrient added to product did not consider nutrition balance of calcium-fortified foods. Units of calcium content were decided by companies, therefore consumers confused labelled content with mouth dose of calcium and the comparison of the amounts added calcium among products was difficult. The amounts of calcium in products were from 16.4 to 1226 mg Per 100 and from 2.5 to 27.6% RDA (recommended daily allowance) per serving size. The amounts of calcium in many products were less than 10% RDA per serving size, whole appraisal about fortified content was needed. And for nutrient labeling on calcium, they used various term whether it is approved by law or not.

  • This survey was conducted from June 2004 to August 2004, through questionnaires given to 432 women aged ranging from 20 to 50 years, who were living in the Seoul metropolitan area. The questionnaires were designed to determine the physique, level of obesity and dieting survey as well as to uncover which diets were in fashion and their satisfaction degree. Dieting-related knowledge and dieting side effects were also investigated. The results were as follows: In dieting survey, as the age increased, dieting for health reason (52.3%) increased, whereas that for aesthetic reasons (32.6%) decreased (p<0.05). The most effective methods of dieting were exercise (50.2%) and diet (45.0%) regimens. In regards to exercise frequency, 46.5% for none, 23.5% for 1-2 times a week, suggesting that most respondents do not practice exercise for dieting purposes (p<0.05). Major source for dieting was shown to be obtained from relative family or friends (31.7%), newspapers or magazines (29.3%) and internet (14.9%). As the age decreased, information from the latter increased, whereas that from TV program (21.2%) decreased (p<0.05). Reasons for excess weight were bad eating habits (39.6%), lack of exercise (38.3%), pregnancy and childbirth (10.6%). In fad dieting, while organic foods and aerobic exercises scored the highest satisfaction degree among diet and exercise regimens, on the other hand, sauna, steam baths and high temperature half-immersion baths scored the highest among surgery and other special therapies. As the age increased, the satisfaction degree for organic foods such as organic vegetable and high functional boiled cooked rice increased (p<0.05). As the age increased, scores on dieting-related knowledge decreased. Side effects of dieting included dizziness 06.2%) fatigue (15.1%) indigestion/constipation (11.1%) physical weakness 00.5%), loss of concentration (7.8%), dry skin (7.4%) loss of motivation (6.7%). The above results showed that attitude toward dieting among adult women varied with age and in light of the well-being trend, organic foods and aerobic exercises scored the highest satisfaction degree through all age.
