Purpose: This study was done to evaluate the validity of the Korean - Child Development Review in screening children with developmental risks. Method: The participants in the study were 172 children aged 6-75 months old and their parents. Data were collected by questionnaire or interview. Korean Denver II and Bayley test were administered with K-CDR for validation of children who were referred for developmental assessment at D University Hospital or public health center. The data were analyzed using correlation, $X^2$ test, and cross tab analysis. Results: There was a significant relationship between the K-CDR and Korean Denver II. The correlation coefficients were .42 to .61 by developmental sector. The sensitivity and specificity of K- CDR were .84 and .66 respectively when "abnormal" with MDI of Bayley test defined as lower than 85 the score which was used as a diagnosis of developmental delay. The responses to 6 questions for parents showed significant differences according to 3 groups by developmental state. Parents of children in the developmental disability group more frequently checked problems from the 26 problem checklist about their children's development and behavior. Conclusion: The results show that K-CDR is valid and has good sensitivity and moderate specificity in screening developmental delay.

Background: The main purpose of this study was to know the educational environment on physical therapists who were working at clinical field after graduation. Methods: The subjects of this study were 241 therapists who took and OMPT or PNF course at Seoul, Incheon and Kyounggido. The data were collected during April to June 2012. The data were analysis by SPSS PC by cross-tab, mean, percentage. Results: The general characteristics of physical therapists who took post-graduate education: female (56.0%), 1-3 years clinical experience (41.5%), 25-29 years old (46.5%). The main reason to take post-graduate educational program was to learn more high quality therapeutic skills for the patients treatment (88.4%). But the condition of environment wes poor such as they pay all of expenses by themselves (54.9%), not permit to take international post-graduate educational program (77.2%). Conclusions : For the better post-graduate educational environment for the physical therapists, it needs systemic plan and sequential strategy with passion for the future.

Manufacturing a multi-layered tablet such as Xatral XL$^{(R)}$ is more complex and expensive than monolayered tablets, but mono-layered tablets may have less favorable release properties depending on the pharmacodynamics and pharmacokinetics of the active ingredient. We therefore sought to develop a monolayer tablet with a similar dissolution profile to the commercial alfuzosin sustained-release triple layered tablet (Xatral XL$^{(R)}$). We prepared four different mono-layered alfuzosin tablets with different concentrations of hydroxypropyl methycellulose and PVP K-90. Fomulation III with alfuzosion/mg-stearate/ HPMC/ PVP K-90 (10/5/110/95 mg/tab) has a similar dissolution rate to Xatral XL$^{(R)}$, with a similarity factor score of 81.4. However, the swelling and erosion rates of the two formulations were different, and NIR analysis showed differences in the mechanisms of drug release. Thus, although formulation III and Xatral XL$^{(R)}$ show similar dissolution rates, the mechanisms of drug release are different.

In this study optimal analysis of pipe network was performed using linear and non linear analysis method for complex real pipe network system of Mungyeong water purification field system which consists of 70 nodes and 86 elements. From the examination result of total flow which is distributed to each pipe, it is found that KYPIPE2 Model supplies less amount than NLAM. It is known that dynamic water level and pressure head of KYPIPE2 Model and NLAM are nearly in accordance with each other from each method of the pipe network analyses, and appeared that both methods of analysis shows high reliable result since the distribution of dynamic water level for every node is the short range of EL. 205.0m~EL. 210.0m besides the pressed dynamic water level. The analysis results of pressure in the methods of pipe network analysis for KYPIPE2 Model and NLAM are similar and it is satisfactory result that the pressure distributions of the tab water design criterion of 5.0kgf/cm$^2$ besides the small part of highland.

Bioequivalence (BE) test of biphenyl dimethyl dicarboxylate (DDB) tablets was performed. Normal healthy male volunteers (n = 20) were randomly divided into 2 groups, and reference $(Nissel{\circledR})$ and test $(Livital{\circledR})$ tablets of DDB $(25mg{\times}8\;Tab.\;= \;200\;mg)$ were given orally by balanced two-period cross-over design. The serum concentration was determined by high performance liquid chromatography. The pharmacokinetic parameters, AUC, $C_{max}$, and $T_{max}$ obtained after drug administration were statistically analyzed. Statistical evaluation of the data involved an analysis of variance (ANOVA) for cross-over design. The results were within 20% differences of mean value in AUC, $C_{max}$, and $T_{max}$ between reference and test tablets. The results of ANOVA showed no significant differences for "between group or subject" and "period". The test tablet was bioequivalent with the reference tablet in the AUC, $C_{max}$, and $T_{max}$.

The feeding effects of Herba hottuynia extracts on the lipids profiles and the content of TAB-reactive substances were evaluated in rats fed a high cholesterol diet. Hot water or ethanol extracts of the dried leave were evaporated and lyophilized . The experimental animals wer edevided to four groups and fed the following diets for 4 weeks : BAsal (cholesterol-free diet), CHOL(cholesterol-enriched diet),CW (cholesterol plus water extract) and CE(cholesterol plus ethanol extract). Dietary cholesterol increased significantly the activities of serum GOT and GPT, but the extracts feeding (0.5% of diet) did not influence the activities induced by dietary cholesterol. Although dietary cholesterol increased significantly the concentrationof serum andliver cholesterol, it tended to decrease the concentation of serum triglycerides. CHolesterol feeding had a lowering effect on the lipid peroxidation value of serum, but not inliver.Furthermore, the extracts feeding, especially water extract, decreased markedly the liver peroxidation value. The results suggest that Houttyunia cordata extracts have an in vivo antioxidant effect, judged from the TBA value in the liver rats fed a high cholesterol diet.

This study was conducted to obtain a better understanding of American green tea consumers for increasing Korean green tea sales in the US market. In doing so, this study investigated green tea choice attributes of US consumers and segmented them based upon their perceptions about important attributes of green tea. A factor-cluster segmentation approach was used for this study. An exploratory factor analysis identified five green tea choice motives: 'Sensory', 'Diet', 'Price', 'Health', and 'Brand'. Based upon these five choice attributes, cluster analyses classified all respondents into four homogeneous subgroups: 'Highly motivated', 'Taste/Price oriented', 'Health oriented', and 'Brand oriented'. Cross-tab tests proved that green tea consumption and purchasing patterns were significantly different among the four clusters. In particular, two cluster groups representing 'Highly motivated' and 'Health oriented' groups were found to offer the most utility for further American green tea market segmentation research. Findings show that American green tea consumers include a wide range of age groups and they usually buy green tea at grocery markets. Managerial implications for all cluster groups based upon their unique characteristics are provided. Korean green tea companies can apply these findings in order to develop more effective and efficient marketing strategies to attract American consumers to buy more Korean green tea.

This study is conducted to find out whether companies which use electronic commerce for their business are collecting the least personal information. of consumers that are necessary for providing electronic commerce services to consumers. Investigators visited website of 799 electronic commerce companies, and checked out the personal informations of consumers that were asked when they join the site as a member. The collected data were analyzed with frequency, percentage, and cross-tab analysis using SPSS program. Generally most electronic commerces required more personal information of consumers than necessary for providing their services to consumers. These phenomena are partly due to the fact that regulations regarding consumer privacy in electronic commerce are advisory rather than mandatory at present. Therefore, it is suggested that mandatory regulation which makes companies poot their identification within a certain area of their web page has to enforced for the protection of consumer privacy in electronic commerce. And it would be more efficient if consumers are consistently educated about self protection guideline regarding personal information in using electronic commerce in addition to a mandatory regulation.
