The purposes of this study were to identify the household's financial status by life cycle stage and no analyze contributing factors to financial planning for retirement preparation among Korean marred couples. For these purpose, 2074 married couples those being under 55 and having either single earner or dual earners were selected, and total sample was divided into three stages; young-aged(＜35), middle-aged(35-44) & old-aged(45-54). Statistics were frequencies, means, percentile, and logistic analysis. The results were as follows. First, old-aged had higher level of total income, total expenditure and total assets than either young-aged or middle-aged. In addition, households those holding private pensions were likely to have higher total income, total expenditure and total assets than those owning no private pension. while middle-aged had a highest total debts. Second, gini coefficients of total income and total expenditure between three aged groups were similar, but old-aged had the highest gini coefficient of total assets and total debts. In particular, gini coefficients of total assets and total debts of households those having no private pension were greater than those holding private pensions. third, contributing factors to private pension ownership of young-aged were family & household-related factor and financial factor, middle-aged's factors were household head's characteristics and financial factor. Also, old-aged's factors were household head's characteristics, family & household-related factor and financial factor.

This study was conducted to investigate the changes in contents of total flavonoid and total polyphenol of three leafy vegetables, spinach(Spinacia oleracea L.), chard(Beta vulgaris L.), whorled mallow(Malva verticillata L.) by various blanching times. Total flavonoid and total polyphenol contents of spinach were 21.01 and 25.58 mg/g, those of chard were 26.02 and 35.14 mg/g, and those of whorled mallow were 16.80 and 19.94 mg/g, respectively. Total flavonoid and total polyphenol contents of chard were the highest among the leafy vegetables. Total flavonoid and total polyphenol contents of leafy vegetables were decreased according to blanching time. Especially, total flavonoid content of chard showed significant loss of $15-30\%$ by blanching time. Total polyphenol content of whorled mallow showed loss of $37-39\%$, but the decrease was not significant.

In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxauiol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

The main purpose of this article is for deriving functions related to the prediction of the closure of the hospitals, and finding out how the discriminant functions affect the closure of the hospitals. Empirical data were collected from 3 years financial statements of 41 private hospitals closed down from 2000 till 2006 and 62 private hospitals in business till now. As a result, the functions related to the prediction of the closure of the private hospital are 4 indices: Return on Assets, Operating Margin, Normal Profit Total Assets, Interest expenses to Total borrowings and bonds payable. From these discriminant functions predicting the closure, I found that the profitability indices - Return on Assets, Operating Margin, Normal Profit Total Assets - are the significant affecting factors. The discriminant functions predicting the closure of the group of the hospitals, 3 years before the closure were Normal Profit to Gross Revenues, Total borrowings and bonds payable to total assets, Total Assets Turnover, Total borrowings and bonds payable to Revenues, Interest expenses to Total borrowings and bonds payable and among them Normal Profit to Gross Revenues, Total borrowings and bonds payable to total assets, Total Assets Turnover, Total borrowings and bonds payable to Revenues are the significant affecting factors. However 2 years before the closure, the discriminant functions predicting the closure of the hospital were Interest expenses to Total borrowings and bonds payable and it was the significant affecting factor. And, one year before the closure, the discriminant functions predicting the closure were Total Assets Turnover, Fixed Assets Turnover, Growth Rate of Total Assets, Growth Rate of Revenues, Interest expenses to Revenues, Interest expenses to Total borrowings and bonds payable. Among them, Total Assets Turnover, Growth Rate of Revenues, Interest expenses to Revenues were the significant affecting factors.

This study was conducted longitudinally following the total nitrogen , total lipid, and lactose concentrations and their factors on concentrations of energy-yielding nutrients in human milk from 2-5 days to 12 weeks postpartum of 45 lactating Korean mothers. All samples were from well-defined subjects. And uniform collection procedures were used . Total nitrogen concentration of milk decreased significantly from 385mg/이 at 2-5 days to 201mg/dl at 12 weeks postpartum. Total lipid concentration increased from 1.98g/dl at 2-5 days to 3.09g/dl at 12 weeks postpartum. However, there was a large variation in the concentration of total lipids. Lactose concentration increased signifciantly from 6.53g/dl at 2-5 days to 7.48g/dl at 12 weeks. Total nitrogen concentration in milk was positively related to pregnancy weight gains at 2 and 6 weeks postpartum. Total lipid concentration was positively related to infant birth weight : however, it was negatively related to the maternal weight loss. In addition, total lipid concentration was positively related to parity and maternal percentage body fat at 12 weeks postpartum. Milk lactose concentration was positively related to parity at 2 weeks postpartum.

This study was carried out to investigate the level of total glucosinolates in different parts (outer and inner part) of fresh, salted Chinese cabbage ($Brassica$ $campestris$ L. ssp. $Pekinensis$) and Kimchi at different harvesting periods (June-July, August-September, October-November, December-April, and May). For determination of total glucosinolates, Chinese cabbage was used for analytical sample preparation, provided with an anion exchanges column and measured by UV-visible Spectrophotometer. The fresh Chinese cabbage (FCC) that was harvested in June-July contained the highest level of total glucosinolates and was higher in outer part than inner part in all harvesting periods. The salted Chinese cabbage (SCC) that was harvested in May contained the lowest level of total glucosinolates. Total glucosinolates level of SCC in outer part was higher in June-July and August-September. The manufactured Kimchi (K) using harvested Chinese cabbage in June-July and August-September contained the highest level of total glucosinolates while that harvested in May contained the lowest level. The level of total glucosinolates in different parts was higher in inner part than outer part in all harvesting periods except for May. In all harvesting times, the level of total glucosinolates of FCC was higher than processed Chinese cabbage (SCC and K). Based on these results, levels of total glucosinolates are influenced by harvesting periods, parts and processing conditions of Chinese cabbage.

Let ${\kappa}$ be a positive integer and let G be a simple graph with vertex set V(G). A function f : V (G) ${\rightarrow}$ {-1, 1} is called a signed total ${\kappa}$-dominating function if ${\sum}_{u{\in}N({\upsilon})}f(u){\geq}{\kappa}$ for each vertex ${\upsilon}{\in}V(G)$. A set ${f_1,f_2,{\ldots},f_d}$ of signed total ${\kappa}$-dominating functions of G with the property that ${\sum}^d_{i=1}f_i({\upsilon}){\leq}1$ for each ${\upsilon}{\in}V(G)$, is called a signed total ${\kappa}$-dominating family (of functions) of G. The maximum number of functions in a signed total ${\kappa}$-dominating family of G is the signed total k-domatic number of G, denoted by $d^t_{kS}$(G). In this note we initiate the study of the signed total k-domatic numbers of graphs and present some sharp upper bounds for this parameter. We also determine the signed total signed total ${\kappa}$-domatic numbers of complete graphs and complete bipartite graphs.

To clarify the safety of both total and near-total thyroidectomy, and to guide a selectionof an adequate type of surgical treatment of thyroid diseases, 192 consecutive total or near-total thyroidectomy cases were reviewed. They were divided into two groups: ont, the total thyroidectomy group(Group T,N=111) and the other, the near-total thyroidectomy group (Group NT, N=81). In both groups, complication rates, associations of complication rates with extents of surgery and stage of lesion were observed. Complication rate was significantly higher in Group T (53.6% vs 12.3%, p<0.05). But the rate of permanent complications such as permanent hypoparathyroidism and recurrent laryngeal nerve injury was remarkably low(4.5% in Group T, 6.0% in Group NT) and shows no significant difference in both groups. There was no permanent complication in cases where any type of neck dissection had not been performed regardless of the type thyroidectomy. But among whom underwent central compartmental neck dissection(CCND) and functional neck dissection(FND), 4(4.4%) and 4(6.4%) cases showed permanent complications. There was no statistical significance in differences between Group I and NT. In cases who underwent concomittant classical radical neck dissection(RND), 3(25.5%) showed permament complications. In this subgroups, complications were significantly higher in Group T(p<0.005). Complications were also directly related to the stage of the lesion. Only one patient showed permanent complication in 74 intracapsular lesions but 9 permanent complications were observed in 118 advanced lesions. We could clarify both total and near-total thyroidectomy were safe operations and the complications were related to accompanying neck dissections and the disease status rather than total or near-total thyroidectomy itself. Thus, we think that for the cases where higher complication rates are expected, such as locally advanced thryoid cancers or the cases which required wider neck dissection, the near-total thyroidectomy would be a preferrable method.
