As the public becomes concerned with looking younger and healthy, aesthetic considerations will become more relevant to dental treatment planning. The purpose of this study was to evaluate the relationship between interdental papilla existence and the distance from contact point to interdental alveolar crest in the maxillary anterior dentition of korean. Fifty-nine Korean adult consist of adults. 34 males and 25 females participated in the study. Papilla Index(PI) was recorded. The distance between contact point and interdental alveolar crest was measured by sounding with Williams probe. Measurement were carried out in 257 maxillary anterior interproximal area. The results showed that mean PI was 1.95 and mean distance between contact point and interdental alveolar crest was 5.07mm. The correlation between the papilla index and distance was negative and statistically significant(r=-0.819; p=0.000). A high negative correlation existed between PI and distance from contact point to alveolar crest. When the distance between contact point and alveolar crest was 4mm, the papilla got lost on a half of all cases. When the distance was 5mm, the papilla was present almost 11%. When the distance was 6mm, the papilla was present 4%. When the distance was 7mm or more, the papilla was lost in all cases.

Purpose: The purpose of this descriptive study was to examine the knowledge, attitudes and prevention behavior to AIDS of nurses. Method: The subject of this study were 217 nurses in Busan. Data was analyzed by using descriptive statistics, t-test, ANOVA, Pearson's correlation, and Scheffe's test. Results: Total knowledge of AIDS(mean score was 6.71 out of 12) was average. Total attitudes of AIDS(mean score was 13.16 out of 25)was average. Prevention behaviors were above average(mean score was 57.63 out of 75). According to the results of analyzing the difference between general characteristics of the subject and AIDS related knowledge, attitudes and prevention behaviors, a significant difference was present with religion(p<.05) in attitudes score; with age(p<.001), marital status(p<.001), education level(p<.05), position(p<.05) and clinical experience(p<.05) in prevention behaviors. According to the results of analyzing the difference between AIDS related characteristics of the subject and AIDS related knowledge, attitudes and perceived behaviors, a significant difference was present with experience in taking care of HIV/AIDS patients(t=2.19, p<.05) in attitudes score; and experience in HIV positive after care(t=-2.64, p<.01) and general nursing training about AIDS(t=2.23, p<.01). There was a positive correlation among knowledge score and attitudes score(r=.170, p<.05). Conclusion: These findings suggested that AIDS education and training programs should be developed and run for nurses. Expecially, health education related with AIDS is needed in young and less experienced nurses. In following such a program, there will be greater compliance with prevention behaviors. Furthermore, it is necessary to provide work-related guidelines regarding AIDS for nurses.

Second-order rate constants (k$_{Nu–}$) have been measured for nucleophilic substitution reactions of Y-substituted phenyl benzoates (1a-i) with butane-2,3-dione monoximate ($Ox^-\;an\;\alpha$-nucleophile) and Z-substituted phenoxides in 80 mol% H$_2$O/20 mol% DMSO at 25.0${\pm}$0.1$^{\circ}C$. Hammett plots correlated with ${\sigma}^o$ and ${\sigma}^-$ constants for reactions of 1a-h with Ox$^–$ exhibit many scattered points. In contrast, the Yukawa-Tsuno plot results in a good linear correlation with ${\rho}_Y$ = 2.20 and r = 0.45, indicating that expulsion of the leaving group occurs in the rate-determining step (RDS). A stepwise mechanism with expulsion of the leaving-group being the RDS has been excluded, since Y-substituted phenoxides are less basic and better nucleofuges than Ox$^–$. Thus, the reactions have been concluded to proceed through a concerted mechanism. Ox$^–$ is over 10$^2$ times more reactive than its reference nucleophile, 4-chlorophenoxide (4-ClPhO$^–$). One might suggest that stabilization of the transition-state (TS) through intramolecular general acid/base catalysis is responsible for the ${\alpha}$-effect since such general acid/base catalysis is not possible for the corresponding reactions with 4-ClPhO$^–$. However, destabilization of the ground-state (GS) of Ox$^–$ has been concluded to be mainly responsible for the ${\alpha}$-effect found in this study on the basis of the fact that the magnitude of the ${\alpha}$-effect is independent of the nature of the substituent Y.

The purpose of this study was to examine the knowledge and attitude of breast feeding and to explore the predictive variables for the intention of breast feeding of mothers. One hundred and thirty-five mothers who delivered at the D University hospital during the period of May to June in 1996 comprised the sample. Data were collected by questionnaire methods before discharge at the hospital. Data were analyzed using percent, 1-test, and logistic regression. The results were as follows : 1. During their pregnancy, majority of mothers (74.8%) got the breast feeding information. Information sources were book (34.5%), family and relatives(32.4%), mass media(24.3%), and professionals such as nurses and doctors (8.8% ). The frequently reported sources of most encouragement for breast feeding were mother in law(20.7%) and baby's father (11.1% ). 2. The mean score of the items of Knowledge and Attitude toward Breast Feeding Scale were 42.56 (SD=5.47) and 39.07(SD=5.15) , representing positive attitude toward breast feeding. The correlation between knowledge and attitude score was significant(r 〓.54, p<.001). Knowledge of breast feeding were significantly different between breast feeding intention group (including partial breast feeding) and artificial feeding intention group(t=2.79, p<.01) 3. Logistic regression analysis revealed that feeding method in the hospital, delivery type, knowledge toward breast feeding, disease related to pregnancy, complication related to delivery, and educational level of mother were predictives of the intention of breast feeding. 4. The most frequently rated reasons for the plan for mixed feeding were concern about insufficient milk (37.9%) and work(27.6%), The major reasons for plan for artificial milk feeding were having premature baby(25.9%) and maternal health problems including infection(14.8% ) and drug use due to chronic illness (14.8%). From the result of the study, it is recommended to develop supportive nursing intervention strategy to promote breast-feeding intention and practice. The intervention could be more effective to begin early in pregnancy and include teaching for breast feeding skills as well as information provision for positive attitude formation.

New diamide chiral stationary phases of four systematically substituted optically active N-(N-benzoyl-L-amino acid)-anilide synthesized from L-valine, L-leucine, L-isoleucine, and L-phenylalanine were described. The behaviors of these diamides as optically active stationary phases for the separation of N-trifluoroacetyl-D,L-amino acids were examined with respect to separation factors(${\alpha}$) and thermodynamic properties of interaction. The separation of twelve N-trifluoroacetyl-D,L-amino acid isopropyl esters were improved by the order of N-(N-benzoyl-L-leucyl)-anilide>N-(N-benzoyl-L-isoleucyl)-anilide>N-(N-benzoyl-L-valyl)-anilide>N-(N-benzoyl-L-phenylalanyl)-anilide. Eight amino acid derivatives with non-polar R-group and threonine, serine, aspartic acid, and glutamic acid enantiomers were separated on N-(N-benzoyl-L-leucyl)-anilide as chiral stationary phase with good separation factor between 1.07-1.25. The separation factors decreased with respect to increasing column temperature. Possible working temperature of diamide phase was between $130-190^{\circ}C$ for N-(N-benzoyl-L-phenylalanyl)-anilide and $130-180^{\circ}C$ for other three diamide phases. The differential Gibb's free energy (${\Delta}{\Delta}G$) of enantiomers was in the range of -100--180 cal/mol for ten amino acids and -40--60 cal/mol for alanine and aspartic acid.

The aims of this study were to investigate the correlation between the electromyographic (EMG) activity of the abductor hallucis (AbdH) and the amount of pressure measured by a pinch gauge (PG), and to compare the EMG activity of AbdH and the pressure measured by the PG during short foot (SF) exercise in subjects with pes planus and in subjects with a neutral foot alignment. Fourteen subjects were recruited for this study (pes planus group=7; neutral foot alignment group=7). A surface EMG was used to collect AbdH activity, and a PG was positioned under the first metatarsophalangeal joint to measure the pressure produced by the first metatarsal head during the SF exercise. The AbdH activity and the pressure measured by the PG showed a positive good correlation (r=.80, p<.05). The EMG activity of the AbdH and the pressure measured by the PG were significantly lower for subjects with pes planus than for subjects with a neutral foot alignment (p<.05). Based on these findings, the PG can be recommended as an effective instrument for evaluating the performance of the AbdH. It may also be beneficial for monitoring how well the SF exercise is performed, and for providing visual feedback to patients with pes planus during SF exercise in a clinical setting.

Objectives : This study was to examine the social value of dental hygienists, their values about the health system and the relationship of all the related variables. Methods : The subjects in this study were 205 dental hygienists who worked in dental clinics and hospitals on Seoul. A survey was conducted from August 12 to October 15, 2010. The questionnaire consisted of nine items about general characteristics, two items about social values and 11 about values of the health system. The items related to social values and values of the health system were prepared by translating the items used in David et al's study, and the Cronbach alpha coefficient of those items respectively 0.80 and 0.76. Results : The dental hygienists got 3.94 in social values, which was above the average. In terms of values about the health care system, their values of the treatment delivery system(3.92) rated highest, followed by values of patient rights(3.79) and values of institutional restrictions(3.25). Their socal values had a closest positive correlation to their values of the treatment delivery system, and their values of patient rights had a strong positive correlation to those of the treatment delivery system and was positively correlated to those of institutional regulations as well. And there was a positive correlation between their values of the treatment delivery system and institutional regulations(r=.276). Conclusions : The above-mentioned findings illustrated that the social values of the dental hygienists had a positive correlation to their values of the health system. Therefore the kinds of educational programs that help dental hygienists to build their social values and values of the health system should be developed to improve their job efficiency as oral health experts.

In the present work, we have studied low temperature sintering and microwave dielectric properties of $ZnAl_2O_4$-zinc borosilicate (ZBS, 65ZnO-$25B_2O_3-10SiO_2$) glass composites. The focus of this paper was on the improvement of sinterability, low dielectric constant, and on the theoretical proof regarding of microwave dielectric properties in $ZnAl_2O_4$-ZBS glass composites, respectively. The $ZnAl_2O_4$ with 60 vo1% ZBS glass ensured successful sintering below $900^{\circ}C$. It is considered that the non-reactive liquid phase sintering (NPLS) occurred. In addition, $ZnAl_2O_4$ was observed in the $ZnAl_2O_4$-(x)ZBS composites, indicating that there were no reactions between $ZnAl_2O_4$ and ZBS glass. $ZnB_2O_4\;and\;Zn_2SiO_4$ with the willemite structure as the secondary phase was observed in the all $ZnAl_2O_4$-(x)ZBScomposites. In terms of dielectric properties, the application of the $ZnAl_2O_4$-(x)ZBS composites sintered at $900^{\circ}C$ to LTCC substrate were shown to be appropriate; $ZnAl_2O_4$-60ZBS (${\varepsilon}_r$= 6.7, $Q{\times}f$ value= 13,000 GHz, ${\tau}_f$= -30 ppm/$^{\circ}C$). Also, in this work was possible theoretical proof regarding of microwave dielectric properties in $ZnAl_2O_4$-(x)ZBS composites.
