To determine patterns of preference for and consumption of milk and milk products in Seoul city, a study was conducted of 724 girls and 587 boys ranging in age from elementary school to collage level, from July to August, 1974. Findings are summarized as follows: In general, milk and milk products were liked by both children and adults. A contrasting low tendency to purchase such products was due to socioeconomics, habitual, and educational factors, as well as a lack of adequate nutritional information, especially with regard to milk. Knowledge of the value of milk as a source of calcium was lacking, especially among boys. The majority of homemakers understood that milk was nutritious, but not specifically as the best source of calcium for their families. Milk, especially in beverage form, was commonly regarded as food for the infant and small child. Grandparents would not drink it. Such a beliefe is similar to that found in under-developed or developing nations. The need for nutrition education must be emphasized. Milk and milk products are expensive foods, particularly for the low income family; but even in higher income levels, consumption was limited. Milk was consumed mostly by the younger family members, less by the older. Among the children, preference, knowledge, and concern with the nutritional value of milk increased with age of subjects. It is presumed that awareness improved with increasing length of school education. Greater frequency of milk intolerance was found with decreasing age of respondents: about 10 percent had some form of milk intolerance. This percentage will be found to be much higher in villages where milk is less familiar. This study indicated that respondents liked ice cream best of all the milk products. For beverage, they preferred cider and cola in summer, coffee and milk in winter. Smaller families consumed more milk than larger families. Household consumption of condensed milk was very low, mostly as coffeemate. Among households interviewed, as many had regular as irregular delivery of dairy milk. Average consumption ranged 0.5 to 1.5 Hop. Engel indices of these families ranged 20 to 60. Use of milk at home was very simple. Not many methods of preparation were found. The milk was used mostly as beverage. In order to improve the nutritional level of Korean children and adults who especially need additional calcium, milk and milk products are recommended as the best source of calcium. Nutrition education of children and their parents should receive greater emphasis.

The seasonal variations of chemical composition of jujuba leaf were studied by analyzing general composition, amino acid composition, fatty acid composition, mineral, phenol, condensed tannin, flavonoid contents. Fresh jujuba leaf contained 4.42~6.31% protein and 4.31~5.71% fat on wet basis. Jujuba leaf was rich in aspartic acid, glutamic acid and leucine, but methionine was a limiting amino acid. Four kinds of free sugar, i.e. glucose, fructose, sucrose and maltose were found in jujuba leaf. The contents of fructose and glucose increased during growth, while the contents of disaccharides, sucrose and maltose, decreased. The main fatty acids of the leaf were palmitic acid, linoleic acid, stearic acid and oleic acid. Jujuba leaf was rich in K, Na and Ca, however, the amounts of Fe, Mn and Cu were low. The contents of Ca and Na increased during growth but the content of Mg decreased. The content of total phenolic compound was 0.83~0.89% and the content of condensed tannin was 0.40~0.45%. Two major flavonoids such as rutin and isoquercitrin were detected and their contents were 103.8~125.2mg/kg and 26.2~40.0mg/kg, respectively.

Although exogenous protease enzymes have been used in poultry diets quite extensively, this has not been the case for pig diets. In general, due to their better gut fermentative capacity and longer transit time, pigs have greater capacity to digest dietary proteins than poultry. However, in early-weaned piglets, the stress brought about by weaning adversely affects the digestion of dietary proteins. Therefore, a study was conducted to determine the effects of a commercial protease enzyme in weanling pigs. Indices of growth, nutrient digestibility, blood profiles, fecal microflora, fecal gas emission and fecal scores were measured during the study. A total of 50 weanling pigs ($6.42{\pm}0.12kg$) at 28 d of age were randomly assigned to receive 1 of 2 dietary treatments: i) control diet (corn-soy based) with no supplemental protease (CON), and ii) control diet+200 g/ton protease (PROT) for 42 d. A completely randomized design consisting of 2 treatments, 5 replicates, and 5 pigs in each replicate was used. Growth performance in terms of body weight ($27.04{\pm}0.38kg$ vs $25.75{\pm}0.39kg$; p<0.05) and average daily gain ($491{\pm}7.40g$ vs $460{\pm}7.46g$; p<0.05) in PROT fed pigs were increased significantly, but gain per feed ($0.700{\pm}0.01$ vs $0.678{\pm}0.01$; p>0.05) was similar between treatments at d 42. Relative to CON pigs, PROT fed pigs had increased (p<0.05) apparent total tract digestibility ($84.66%{\pm}0.65%$ vs $81.21%{\pm}1.13%$ dry matter and $84.02%{\pm}0.52%$ vs $80.47%{\pm}1.22%$ nitrogen) and decreased (p<0.05) $NH_3$ emission ($2.0{\pm}0.16ppm$ vs $1.2{\pm}0.12ppm$) in the feces at d 42. Except for a decreased (p<0.05) in blood creatinine level, no differences were observed in red blood cell, white blood cell, lymphocyte, urea nitrogen, and IgG concentrations between treatments. Fecal score and fecal microflora (Lactobacillus and E. coli) were also similar between CON and PROT groups. Overall, the supplementation of protease enzyme in weanling pigs resulted in improved growth rate and nutrient digestibility. Exogenous protease enzyme reduced fecal $NH_3$ emission, thus, potentially serving as a tool in lowering noxious gas contribution of livestock production in the environment.
Background: The DR-$70^{TM}$ immunoassay is a newly developed cancer diagnostic test which quantifies the serum fibrin degradation products (FDP), produced during fibrinolysis, by antibody reaction. The purpose of this study was to evaluate the potential of DR-$70^{TM}$ Immunoassay in screening malignant tumor. Methods: Sample subjects were 4,169 adults, both male and female, who visited the health promotion center of a general hospital from March 2004 to April 2005 and underwent the DR-$70^{TM}$ immunoassay test and other tests for cancer diagnosis. The patient group was defined as 42 adults out of the sample subjects who were newly diagnosed with cancer during the same time period when the DR-$70^{TM}$ immunoassay test was performed. Final confirmation of a malignant tumor was made by pathological analysis. Results: The mean DR-$70^{TM}$ level was $0.83{\pm}0.65{\mu}g/ml$ (range: 0.00 (0.0001)${\sim}7.42{\mu}g/ml)$ in the control group (n=4,127) as opposed to $2.70{\pm}2.33{\mu}g/ml$ (range: $0.12{\sim}9.30{\mu}g/ml)$ in the cancer group (n=42), and statistical significance was established (p<0.0001, Student t-test). When categorized by the type of malignant tumor, all cancer patients with the exception of the subgroups of colon and rectal cancer showed significantly higher mean DR-$70^{TM}$ levels compared with the control group (p<0.0001, Kruscal-Wallis test). The receiver operating characteristic (ROC) curve analysis revealed ${\geq}1.091{\mu}g/ml$ as the best cut-off value. Using this cut-off value, the DR-$70^{TM}$ immunoassay produced a sensitivity of 71.4%, a specificity of 70.1%, a positive predictability of 69.4%, and a negative predictability of 69.2% (1). Conclusion: A significant increase in the mean DR-$70^{TM}$ value was observed in the cancer group (thyroidal, gastric, breast, hepatic and ovarian) com pared with the control group. In particular, the specificity and sensitivity of the DR-$70^{TM}$ immunoassay was relatively high in the subgroups of breast, gastric, and thyroidal cancer patients. There is need for further studies on a large number of malignant tumor patients to see how the DR-$70^{TM}$ level might be changed according to the differentiation grade and postoperative prognosis of the malignant tumor.
The purpose of this descriptive study was to identify the homecare needs of patients with cancer and to provide a basis of interventions. One hundred and two patients at one general hospital in Gyeongnam responded to a questionnaire developed on the basis of care needs perceived by nurses caring for hospitalized patients with cancer. The questionnaire was a Likert type 5 point scale with 56 items on five need categories ; 1) informational 2) physical care : 3) emotional care 4) socioeconomic care and 5) special care needs. Internal consistency of this questionnaire was Cronbach's $\alpha$=.9101 for total items. The data was collected from March 1st to May 31th, 1998, by two graduate nurses. In the data analysis, mean & standard deviation were calculated to identify the degree of care need of each item, and the t-test & ANOVA were done to determine the effects of patients' demographic background on their care needs. The findings are summarized as follows ; 1) The mean score of total of need items was 3.048. Of the four need categories the highest score was informational at 3.4, followed by emotional care, 3.063, physical care, 2.623, and socioeconomic care, 2.599. 2) In the informational need category there were four subcategories with 19 items. Medication and pain control had the highest score, 3.755 ; second was diet and exercise, 3.613 ; third was disease and treatment process, 3.337 ; and last was personal hygiene and infection prevention at 2.687. 3) In the physical care need category there was nine items, IV infusion for nutrition and management of treatment complication was above 3.2 points and the remaining items were in the 2.847-2.070 score ranges. 4) In the emotional care need category there were seven items. The highest need was in support for relationships with health personnel, 3.673. The need for support of religions beliefs and support for having a religion were low at about 2 points. 5) In the socioeconomic care need category there were six items. Support for medical insurance expansion and financial support were above 3 points. Legal support and support for caring of children were low in the care needs. 6) In the special care need category the there were 15 items. Informational need about immunization and informational need about effects of disease on growth and development were high, above 4.1 points. Need for decubitus care and prevention, sitz bath and incontinence care were low, below 2 points. 7) There were significant differences in degree of care need according to admission rate, education level, marital status, religion and caregiver's religion. In conclusion, homecare needs perceived by hospitalized patient's with cancer was moderate, but informational need was higher than direct care need, leading to the conclusion that the provision of sufficient information to patients with cancer at discharge is needed. Nursing interventions should be developed considering the patient's background.
The purpose of this study was to estimate the forecast of bed demand for institutional long-term care for the elderly persons in Taegu Metropolitan City. The study subject was the total 1,877 elderly persons over age 65 living in Taegu.

Extracellular matrix(ECM) is known to function as a reservoir of endogenous growth factors, can be an effective delivery system of growth factor that easily lost bioactivity in solution. Fibrillar collagens like type I collagen, are the major constituent of the ECM and structural protein of bone. Also, it can be a scaffold for osteoblast migration. The purpose of this study was to compare the effects of absorbable Atelo-collagen Sponge($Teruplug^{(R)}$) insertion in tooth extraction sites on periodontal healing of the mandibular second molar after the extraction of the impacted third molar. The study population comprised 31 cases who had been scheduled for surgical removal of impacted mandibular third molars. All patients were in good general health and were not using any medication that would influence wound healing after surgery. In 15 cases control group, none was inserted into the tooth extraction site. In 16 cases experimental groups, $Teruplug^{(R)}$ was inserted into the tooth extraction site. We evaluated tooth mobility, pocket depth, gingival margin level preoperatively and 1 week, 2 weeks, 4 weeks, and 3 months postoperatively. The change was compared with two groups using Mann-Whitney test. The results were as follows. 1. There was no significant change of tooth mobility on both groups. 2. There was tendency of decreasing of previous pocket depth causing tooth extraction on both groups. 3. On gingival margin level, there was various change according to initial swelling and loss of attachment on both groups. 4. There was tendency of decreasing of gingival margin level on both groups because of removal of inflammation and decreasing of previous pocket depth. 5. There was large change of pocket depth on buccal middle, distal, lingual distal area because of tooth extraction and bone reduction. Compared with the control group and experimental group, we observed significant difference during some periods. The results of this study suggest that absorbable atelo-collagen sponge($Teruplug^{(R)}$) is relatively favorable bone void filler with prevention of tissue collapse, food packing and enhance periodontal healing.

We studied 1809 oral cancer patients who visited and were treated in 2002 at the 148 institutions certified as training facilities by the Japanese Society of Oral and Maxillofacial Surgeons, which is composed of 39 dental university hospitals, 44 medical university hospitals, 64 general hospitals, and 1 unknown institution. The patients consisted of 1071 (59.2%) males and 738 (40.8%) females (male:female ratio, 1.45:1), who had a mean age of 65.2 years old. The tongue (40.2%) was the most common site affected, followed by the gingiva (32.7%), buccal mucosa (10.1%), and oral floor (9.0%). There were 6 cases of intraoral multiple cancer. In histopathological examinations, squamous cell carcinoma (88.7%) was the most common type found, followed by adenoid cystic carcinoma (2.1%), and mucoepidermoid carcinoma (1.7%). In addition, non-epithelial tumors comprised 1.8%, among which malignant melanoma was the most common type. Cases classified as T2N0 were the most common (32.1%), followed by T1N0 (21.4%), T4N0 (8.0%), and T2N1 (7.6%). Distant metastasis occurred in 17 patients (1.0%). The sizes of the non-epithelial malignant tumors ranged from 1.0 to 7.0 cm, with a mean size of 3.7 cm.
Recent studies have demonstrated that smoking may be one of the most significant risk factors in the development and progression of periodontal disease. Reports have indicated that smoking causes gingival blood flow to be decreased. However, studies on the effects of smoking on gingival blood flow have yielded contradictory results. The purpose of the present study was to determine the effect of smoking on gingival blood flow. One hundred volunteers(fifty non-smokers and fifty smokers) with good general and periodontal health, aged twenties(non-smoker : 22-29 years, mean=25.36, smoker : 23-29 years, mean=26.64) were selected. Laser Doppler flowmetry (floLAB, Moor Instruments Ltd., England) was applied to measure the gingival blood flow of interdental papilla, marginal gingiva, attached gingiva and alveolar mucosa of left and right upper lateral incisors. In smokers, following an overnight abstinence from smoking, gingival blood flow was measured before smoking, immediately after smoking, 1-, 2-, 3-, 4-, 5- and 6- hour after smoking from 9 a.m. to 3:30 p.m. The difference of blood flow in each tissue of non-smokers and that of each measuring time and each tissue of smokers were statistically analyzed by one way ANOVA and Tukey test. And the difference of blood flow between smokers and nonsmokers in each tissue was statistically analyzed by t-test. The results were as follows : 1. Mean blood flow was highest in alveolar mucosa, followed by interdental papilla, attached gingiva and marginal gingiva in both smokers and nonsmokers. There was a statistically significant difference in each tissue(p<0.05) . 2. There was no consistent result between mean blood flow before smoking in smokers and that of nonsmokers in each tissue. 3. There was a statistically significant difference between gingival blood flow at measuring time point and gingival blood flow of smokers in each tissue(p<0.05). The present study suggested that smoking could alter the gingival blood flow, thus might be partly contributed to periodontal destruction.
This study evaluated the effects of chronic ethanol consumption and/or taurine supplementation on hepatic total, phospholipid fatty acid composition and the metabolism of rats fed one of three purified liquid diets for 8 weeks. the rats followed either the control diet (CD, ethanol-free and taurine-free diet); ethanol diet (ED, CD+ 50g ethanol/L) or ethanol-taurine diet (ETD, ED+3.75g taurne/L). Chronic ethanol consumption and/or dietary taurine supplementation were associated with altered hepatic total and phospholipid fatty acid composition. compared to the values for the control rats, ED or ETD significantly decreased the percentage of total monounsaturated fatty acids ($\Sigma$MUFA), and increased the percentage of total polyunsaturated fatty acids ($\Sigma$PUFA) of hepatic total lipids(p〈0.01). Percentages of 14:0(P〈0.01) and 16:0(p〈0.001) were sigificantly lower, and those of 18:0(p〈0.01), 20:0(p〈0.001), 20:3$\omega$6(p〈0.01) and 22:4$\omega$6(p〈0.01) in hepatic total fatty acid compositions were oserved in rats fed ETD versus those fed ED or ETD. No significant differences in hepatic total fatty acid compositions were observed in rats fed ETD versus those fed ED. Percentages of 24:0(p〈0.01), 16:1(p〈0.05), 20:1(p〈0.01), 18:2$\omega$6(p〈0.01) and 18:3$\omega$3(p〈0.05) in hepati phospholipids were significantly higher, and those of 14:0(p〈0.01), 16:0(p〈0.001), 20:3$\omega$3(p〈0.05) in hepatic phospholipids were significantly higher, and those of 14:0(p〈0.01), 16:0(p〈0.001), 20:3$\omega$3(p〈0.001), 22:6$\omega$3(p〈0.001) and $\Sigma$$\omega$3(P〈0.001) were significantly lower in rats fed ED or ETD compared to the values for the control rats. The Δ5 desaturation index(20:3$\omega$6⇒20:4$\omega$6) and elongation index (20:5$\omega$3⇒22:5$\omega$3) of hepatic phospholipid index (20:3$\omega$6⇒20:4$\omega$6) and decreased Δ4 desaturation index (22:5$\omega$3⇒22:6$\omega$3) compared to the values for the ED rats. These changes in hepatic fatty acid composition induced by chronic ethanol consumption and/or taurine supplementation might be associated with the modulations of physical properties of the hepatic cell membrane and its sensitivity to peroxidation damage.
