Purpose: The purpose of this study was to determine the sexual knowledge, and sex education perception and current status of the parents of preschoolers. The objective was to analyze the relationship between sexual knowledge and sex education demands of parents. Method: The method used in this study was a descriptive correlationstudy. The subjects were 278 parents of 3-to-6 year old children in 5 kindergartens located in Seoul. Data were analyzed using frequency, percentage, average, standard deviation, t-test, ANOVA, Scheffe test, and correlation using the SPSS 20.0 program. Result: The results of this study were the following: 1.There was no significantdifference in the sexual knowledge between the father and mother of preschoolers (Father 20.76, Mother 20.73). According to the findings, sexual knowledge was higher when both father and mother were older (P=.005). Similarly, when the economic level of the father and mother was high, sexual knowledge was also high (P=.030). 2.Concerning sexual education perception, it was found out that both father and mother thought that sex education was necessary. 3.In terms of sex education, a significant difference was noted. Mothers conducted sex education more often than fathers (Fathers, 46.7% Mother, 60.3%). Both the father and mother thought that providing sex education would be best in Grades 1-2, especially for ages 6-7. 4.When asked about the demands for sex education in terms of the physical, social, and living aspects, living aspect was the highest demand. It was revealed that both fathers and mothers were aware of the need for sex education, and when parents hadmore sexual knowledge, they would demand more sex education. Accordingly, there was a correlation between parent’s sexual knowledge and demand for sex education (r=.202, p=.001). Conclusion: Since the age,knowledge, education and economic levels of parents were different, it was necessary to develop sexeducation programs in accordance with their levels. In this way, preschooler parents would be able to teach sex education appropriate to their children’s level.

A new thermotropic liquid crystalline copolyester(TLCP) was synthesized by condensation polymerization of 2,6-naphthalene dicarbonyl chloride with the corresponding diol having a tetramethylene and a hexarnethylene group. The blends of the TLCP with PEN were prepared by the coprecipitation from a common solvent. The TLCP and blends (2, 5, 10 and 20wt% TLCP) were characterized in terms of their thermal, mechanical properties and morphology. The TLCP in the melt state showed nematic mesophase identified by thread-like optical texture. The glass transition temperature (T_(g)) and cold crystallization temperature (T_(c)) of PEN in the blends decreased with increasing the content of TLCP and the TLCP acted as anucleating agent for the matrix polymer. Interfacial adhesion between the TLCP and PEN seemed to be poor. The modulus of TLCP/PEN blends was enhanced as the TLCP content increased.

Background: Sclerostin is a secreted Wnt inhibitor produced almost exclusively by osteocytes, which inhibits bone formation. Aromatase inhibitors (AIs), which reduce the conversion of steroids to estrogen, are used to treat endocrine-responsive breast cancer. As AIs lower estrogen levels, they increase bone turnover and lower bone mass. We analyzed changes in serum sclerostin levels in Korean women with breast cancer who were treated with an AI. Methods: We included postmenopausal women with endocrine-responsive breast cancer (n=90; mean age, 57.7 years) treated with an AI, and compared them to healthy premenopausal women (n=36; mean age, 28.0 years). The subjects were randomly assigned to take either 5 mg alendronate with 0.5 μg calcitriol (n=46), or placebo (n=44) for 6 months. Results: Postmenopausal women with breast cancer had significantly higher sclerostin levels compared to those in premenopausal women (27.8±13.6 pmol/L vs. 23.1±4.8 pmol/L, P<0.05). Baseline sclerostin levels positively correlated with either lumbar spine or total hip bone mineral density only in postmenopausal women (r=0.218 and r=0.233; P<0.05, respectively). Serum sclerostin levels increased by 39.9%±10.2% 6 months after AI use in postmenopausal women; however, no difference was observed between the alendronate and placebo groups (39.9%±10.2% vs. 55.9%±9.13%, P>0.05). Conclusion: Serum sclerostin levels increased with absolute deficiency of residual estrogens in postmenopausal women with endocrine-responsive breast cancer who underwent AI therapy with concurrent bone loss.

Extensive selection works on wild yeasts of fruits were carried cut to obtain strains which are applicable to apple wine making. Among the total number of 1,358 yeast strains which were isolated from various fruit samples collected from the vicinity of Daejeon and other regions of Korea, the strains SH-49, SH-129 and SH-338 were found to be useful. Then experiments on their morphological and physiological characteristics, and on the aspects of practical use in apple wine making were proceeded. The results obtained were as follows: 1. The strains SH-49 and SH-129, particularly SH-49, were appeared to have good fermentation ability, tolerance to sulfur dioxide and to produce fine quality of apple wine. 2. Apple wines made by using the strain, SH-49 and SH-129 contained less amount of total acids than those by other strains. 3. Apple wines of SH-49 and SH-129 were clarified rapidly during the primary fermentation period, and their absorbancy at 430 nm after 45 days of storage were approximately half of others. 4. Apple wine of SH-338 contained higher amount of residual sugar and its quality was superior to others. It is considered that this strain could be used in the production of apple wine of a characteristic quality. 5. The strains SH-49 and SH-338 were identified as a Saccharomyces cerevisiae according to Taxanomic Study of Yeasts by Lodder, however, classification of SH-129 was suspended for further study.

A series of wholly aromatic polyesters with side chains were synthesized by solution polycondensation from 2,5-dialkoxyterephthaloyl chlorides with the corresponding diol. The polymers showed the schlieren textures which is indicative of a nematic phase above their melting temperature. The inherent viscosities (η_(inh)) measured at 35℃ in phenol/p-chlorophenol/1,1,2,2-tetrachloroethane were 0.56-0.98 dℓ/g. The glass transition temperature (T_(g)) and melting temperature (T_(m)) decreased with increasing the length of the alkoxy side chain. Initial decomposition temperatures in TGA occurred at 338 ~ 363℃ in N₂ gas and thermal stability of polymers decreased with increasing the length of the side chain.

Background/Aims: Urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been recently discovered and validated as sensitive biomarkers that can predict stage 2 or 3 acute kidney injury (AKI) development in high-risk patients. We aimed to assess whether these biomarkers could predict adverse outcomes and renal recovery in established AKI patients. Methods: This was a single-center study prospectively enrolling 124 patients diagnosed with AKI. TIMP-2, IGFBP7, neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule 1 (KIM-1) levels were measured at the time of diagnosis and the predictive performance of short-term outcomes and renal recovery was assessed. Results: Patients were divided into 4 quartiles according to the initial urinary TIMP-2/IGFBP7 levels. Stage 3 AKI (odds ratio [OR], 17.86), classified by the Kidney Disease Improving Global Outcomes (KDIGO), as well as the third and fourth quartiles of TIMP-2/IGFBP7 (OR, 5.75 and 44.98, respectively), were found to be independent predictors of renal replacement therapy at the time of AKI diagnosis. In addition, KDIGO stage 3 AKI (OR, 2.468) or the third of fourth quartiles of urinary TIMP-2/IGFBP7 (OR, 1.896 and 3.622, respectively) were also found to be useful in predicting nonrecovery of renal function. In a separate analysis of patients with renal recovery at discharge, initial urinary TIMP-2/IGFBP7 or urinary IGFBP7 at discharge could also predict new-onset or progressive chronic kidney disease (CKD). Conclusions: In AKI patients, urine TIMP-2/IGFBP7 could serve as a biomarker for predicting adverse outcomes, renal recovery, or the development and progression of CKD.
