The complex formation from Zn(II) ion and 2-(2-hydroxyethylamino)-2-(hydroxymethyl)-1,3-propanediol (Monotris), Bis(2-hydroxyethyl)imino-tris(hydroxymethyl)methane(Bistris) in aqueous solution at $25^{\circ}C$ and at an ionic strength of 0.10 M have been studied potentiometrically. For the Zn(II)-Monotris system, in the Monotris (L) complex $ZnL^{2+}$, one of the hydroxyl oxygen atoms as well as the amine nitrogen of the ligand are coordinated. In basic media, the coordinated hydroxyl group is deprotonated. For the Zn(II)-Bistris system, in the Bistris(L) complex $ZnL^{2+}$, two of the hydroxyl oxygen atoms as well as the amine nitrogen of the ligand are coordinated. In basic media, one of the coordinated hydroxyl groups is deprotonated. In very high basic media, an additional hydroxyl group undergoes deprotonation. The equilibrium constants for the formation of $ZnL^{2+}$, $ZnLH_{-1}{^+}$, $ZnLH_{-2}$, $Zn_2L_2H_{-2}{^{2+}}$ and $Zn_2L_2H_{-3}{^+}$ have been determined.

P2Y receptors are metabotropic G-protein-coupled receptors, which are involved in many important biologic functions in the central nervous system including retina. Subtypes of P2Y receptors in retinal tissue vary according to the species and the cell types. We examined the molecular and pharmacologic profiles of P2Y purinoceptors in retinoblastoma cell, which has not been identified yet. To achieve this goal, we used $Ca^{2+}$ imaging technique and western blot analysis in WERI-Rb-1 cell, a human retinoblastoma cell line. ATP ($10\;{\mu}M$) elicited strong but transient $[Ca^{2+}]_i$ increase in a concentration dependent manner from more than 80% of the WERI-Rb-1 cells (n=46). Orders of potency of P2Y agonists in evoking $[Ca^{2+}]_i$ transients were 2MeS-ATP>ATP>>UTP=${\alpha}{\beta}$-MeATP, which was compatible with the subclass of $P2Y_1$ receptor. The $[Ca^{2+}]_i$ transients evoked by applications of 2MeS-ATP and/or ATP were also profoundly suppressed in the presence of $P2Y_1$ selective blocker (MRS 2179; $30\;{\mu}M$). $P2Y_1$ receptor expression in WERI-Rb-1 cells was also identified by using western blot. Taken together, $P2Y_1$ receptor is mainly expressed in a retinoblastoma cell, which elicits $Ca^{2+}$ release from internal $Ca^{2+}$ storage sites via the phospholipase C-mediated pathway. $P2Y_1$ receptor activation in retinoblastoma cell could be a useful model to investigate the role of purinergic $[Ca^{2+}]_i$ signaling in neural tissue as well as to find a novel therapeutic target to this lethal cancer.

A survey on the preference of kimchi and actual amounts of kimchi intake conducted from july to october 1999 to get basic information needed for the augmentation of kimchi intake. Total 1,241 of women and men aged $10{\sim}60$ in kyung-nam area participated in this survey. Except people aged $20{\sim}30$, all of subjects, especially in people aged 60 and over, liked fresh prepared kimchi best, and then fermented kimchi. But all of subjects disliked over fermented kimchi.(p<0.001) And women$(4.3{\pm}0.9)$ liked better fresh prepared kimchi than men$(4.2{\pm}1.0)$, men$(4.0{\pm}0.9)$ liked better fermented kimchi than women$(3.9{\pm}1.1)$.(p<0.05) In subjects aged above 40, as age grow up, the preference of fermented kimchi and over fermented kimchi grew lower. All of subjects best liked chinease cabbage kimchi, and then chonggak kimchi, kakdugi, yeulmu kimchi, dongchimi in order. And women liked better nabag kimchi, yeulmu kimchi, sesame leaf kimchi, bek kimchi, cucumber kimchi, godulppegi kimchi than men and men liked better chinease cabbage kimchi, kakdugi, dongchimi than women.(p<0.05) People aged $10{\sim}20$ and above 60 disliked chonggag kimchi. The preference of kakdugi were high in people aged $10{\sim}20$, but as age grow up, the preference of kakdugi became lower.(p<0.001) The preference of nabak kimchi and dongchimi with juice were significantly high in people aged 60 and over but people aged $10{\sim}20$ disliked. Also subjects aged $10{\sim}20$ disliked significantly yeulmu kimchi, sesame leaf kimchi, green onion kimchi, bek kimchi, cucumber kimchi, mustard leaf kimchi and godulppegi kimchi and subjects aged $20{\sim}30$ disliked significantly yeulmu kimchi, mustard leaf kimchi, godulppegi kimchi(p<0.001). But subject aged 30 and older liked all kinds of kimchi. The amounts of kimchi intake in Kyung-nam area were same level of average amount(100g) of korean intake but the amounts of kimchi intake of men$(106.4{\pm}74.0)$ were more than women$(96.9{\pm}69.5)$(p<0.05)

A survey on the preferences and notion about kimchi and kimchi products was conducted from july to october, 1999 to investigate basic information for increasing the consumption of kimchi for sale. 1,241 subjects of women and men aged 10 to 60 in Kyung-nam area participated in this survey. Most of the subjects made kimchi by themselves at home but this rate of making kimchi at home became lower than past, so increment of consumption of kimchi for sale will be expected in the future. When the people buy kimchi, they considered taste first, and then hygiene, nutrition in order. When they purchase kimchi, more men (69.1%) than women(56%) considered taste, but more women(36.1%) than men(20.6%) considered hygiene first. Subjects aged 30 or older groups considered more the hygiene of kimchi than the subjects of $10{\sim}20$ age groups did.(p<0.05) And people of household income over 3 million wons considered more hygiene than people of below 1 million wons income group did. People liked manufactured kimchi the packed with whole or partly transparent material in order to observe the contents.(p<0.05) They liked better kimchi packed with bottle(46.1%) and vinyl(39.6%) than plastic(14.3%) and this tendency was more in the subjects of women(49.8%) and over 30 age groups.(p<0.05) They prefered $200{\sim}500g$ packing unit of kimchi whether the family size were big or small. Among the processed kimchi products, men liked better a rice covered up with kimchi, a pot stew with kimchi or a soup with kimchi, On the other hand, women liked better a dumplings with kimchi, a grilled food with kimchi, a pizza with kimchi.(p<0.05) Subjects aged 10 to 20 years old liked all kinds of kimchi products, but people aged 40 or older disliked them.(p<0.001)

This study aimed to provide basic data on health promotion programs to prevent cardiocerebrovascular Disease by identifying knowledge, attitude and self-efficacy. Data were collected from 198 middle-aged adults in S-city. The data analysis was analyzed with technical statistics and t-test, ANOVA, Pearson's correlation coefficient. There were significant differences in knowledge depending on the age, education level, monthly income and there were significant differences in attitude depending on the education level and monthly income. There were also significant differences in self-efficacy between gender. The correlation analysis also showed a significant correlation between knowledge of cardiovascular disease and attitudes toward prevention(t=.45, p<.001). In other words, the higher your knowledge of cardiovascular disease, the more positive you are about preventing it. Therefore, it is necessary to develop education and mediation programs that can form a positive attitude toward preventing cardiocerebrovascular disease and to develop programs that enhance the self-efficacy of middle-aged men.
