Puopose : Exposure to dietary phytoestrogens such as genistein during early childhood is a growing public health concern. We examined the effect of early exposure to genistein on sexual maturation in immature rats. Methods : Weaning (3wk-old) Sprague-Dawley female rats were assigned to three groups (n=6 for each): fed by high dose of genistein (100 mg/kg/d), low dose of genistein (10 mg/kg/d) and control group. First vaginal opening (VO) day was observed. Structural alterations in the ovary and uterus were assessed by histologically. Expression of genes of $ER{\alpha}$, $ER{\beta}$, and progesterone receptor (PR) in the ovary and uterus were investigated by RT-PCR. Results : High genistein group had earlier VO than control and low genistein group. Graafian follicles and corpora lutea were observed from the ovary of genistein-treated groups, while primary, secondary follicles and small atretic follicles were observed in the control group. Hypertrophy of luminal and glandular uterine epithelia were found in the genistein-treated groups while poor development of gland and fewer myometrial cell layers were evident in control group. In ovary, the transcriptional activities of $ER{\alpha}$ and $ER{\beta}$ were higher in high genistein group than in controls. In uterus, the transcriptional activities of $ER{\alpha}$, $ER{\beta}$ and PR were higher in low genistein group than in controls. Conclusion : Acute exposure to genistein during the prepubertal period could activate the reproductive endocrine system resulting in the early onset of puberty in female rats. Further clinical investigation on the effect of genistein on the sexual maturation in children is warranted.

In this study, we carried out a survey on the degree of recognition for the brand of the Korea Institute of Geoscience and Mineral Resources (KIGAM) to contribute to reestablishing the status and role of KIGAM as an institution that people proud of by effectively delivering KIGAM's various research activities and achievements to people. About 49.9% of external publics recognized that there was relevance between research achievements of geo-technology and national brand. On the contribution of research achievements of geo-technology to promoting Korea's power of science and technology, 42.3% gave positive answers. On research achievements of mineral resources technology, just 14.4% replied they saw such results. As alternatives to promote the degree of recognition for brand, we suggested development of beneficial message, operation of brand management committee, promotion of involvement of research achievements of mineral resources technology about people-friendly subjects, development and distribution of "board game for education on mineral resources technology" for youths, activation of location PR, activation of online Q&A bulletin board, finding out star researchers, and president's PI activities.

The main objective of this paper is to perform an empirical analysis on the relationship between various marketing activities and financial performance of Korean hospitals. A survey was conducted through structured questionnaire for 495 hospitals, and data from 218 hospitals were utilized in the final anaylsis.(response rate: 44%) Survey items include general characteristics of the hospitals(size, type, location), degree of competition, financial performance. marketing organization! budget, and level of various marketing activities in service development, access improvement, promotion, and pricing. We examine descriptive statistics of the response scores on marketing activities to evaluate the current status of marketing management of Korean hospitals, compare the results across hospital size, type and location, and perform regression analysis to investigate the relaionship between marketing and financial performance. Major findings are as follows: 1) About 46% of the responding hospitals have marketing departments although they are named as 'planning' or 'PR' departments, and the marketing budget on average represents 1.74% of the total expenditures. 2) Average level of marketing activities is calculated to be about 3.32 on 5-point scale, meaning that Korean hospitals implement their marketing programs 'somewhat actively'; however, the scores on the areas of marketing plannning and strategy are relatively low. 3) Large hospitals tend to be more active in marketing than small hospitals, and public hospitals' activities in marketing are not lower compared to private hospitals. 4) Level of overall marketing activities is positively related with financial performance measured by various finacial indicators except for profitability, implying that marketing is successful in revenue generation but needs to be more cost-effective. Also, when the marketing variables are separately included in the regression, no significant relationship is found, which means that various marketing activities are more effective when they are collectively implemented.

The effect of Acibenzolar-S-methyl (ASM) and Rahnella aquatilis Ra39 against apple fire blight disease caused by Erwinia amylovora were tested as a possible alternative to streptomycin. In vitro studies, no inhibition effect against the pathogen was found when ASM was tested. Under greenhouse conditions, application of R. aquatilis Ra39 with the highly susceptible M26 rootstock resulted in a marked disease suppression. Application of ASM and strain Ra39 caused a high decrease of the disease, 82% and 58% respectively; this was correlated with a reduction of the growth of the pathogen within host plants up to 64% and 49.5% respectively. Further studies in the field under artificial infection condition during full bloom revealed that application of ASM and R. aquatilis Ra39 with Gala variety resulted in a control effect up to 21 and 29% respectively. In physiological studies, enhanced activities of PR-proteins (chitinase and $\beta$-1, 3-glucanase) were detected, which are well known as biochemical markers for systemic acquired resistance. Application of ASM to apple shoots caused the highest chitinase activity followed by strain Ra39. The enzyme activity was increased after 2, 4 and 6 days from application. In addition, ASM-treatment caused the higher $\beta$-1, 3-glucanase activity than strain Ra39. Maximum enzyme activity was recorded after 6 days from application and then decreased after 8 and 10 days from application.

Interleukin-32 (IL-32) induces a variety of proinflammatory cytokines and chemokines. The IL-32 transcript was reported originally in activated T cells; subsequently, it was demonstrated to be abundantly expressed in epithelial and endothelial cells upon stimulation with inflammatory cytokines. IL-32 is regulated robustly by other major proinflammatory cytokines, thereby suggesting that IL-32 is crucial to inflammation and immune responses. Recently, an IL-32$\alpha$-affinity column was employed in order to isolate an IL-32 binding protein, neutrophil proteinase 3 (PR3). Proteinase 3 processes a variety of inflammatory cytokines, including TNF$\alpha$, IL-$1{\beta}$, IL-8, and IL-32, thereby enhancing their biological activities. In the current study, we designed four PR3-cleaved IL-32 separate domains, identified by potential PR3 cleavage sites in the IL-32$\alpha$ and $\gamma$ polypeptides. The separate domains of the IL-32 isoforms $\alpha$ and $\gamma$ were more active than the intrinsic $\alpha$ and $\gamma$ isoforms. Interestingly, the N-terminal IL-32 isoform $\gamma$ separate domain evidenced the highest levels of biological activity among the IL-32 separate domains.

The synthesis and characterization of ${K_3[Ru(C_2O_4)3]{\cdot}4H_2O\;(C_2O_4}^{2-}$ = oxalato anoin) complex are described, and its redox properties (in buffer solution of pH = 12) have been investigated. This complex is used for in situ generation of oxoruthenates complexes which have been characterized by electronic spectroscopy. Reaction of ${K_3[Ru(C_2O_4)3]{\cdot}4H_2O$ with excess ${S_2O_8}^{2-}$ in molar KOH generates trans-${[RuO_3(OH)_2]^{2-}/S_2O_8}^{2-}$ reagent while with excess ${BrO_3}^-$ in molar $Na_2CO_3$ generates ${[RuO_4]^-/BrO_3}^-$ reagent. Avoiding the direct use of [$RuO_4$] the organic-soluble $(n-Pr_4N)^+[RuO_4]^-$, (TPAP) has been isolated by reaction of $K_3[Ru(C_2O_4)3]{\cdot}4H_2O$ with excess ${BrO_3}^-$ in molar carbonate and n-$Pr_4$NOH. In a mixture of $H_2O/CCl_4$ ruthenium tetraoxide can be generated by reaction of $K_3[Ru(C_2O_4)3]{\cdot}4H_2O$ with excess ${IO_4}^-$. The catalytic activities of oxoruthenates that have been made from $K_3[Ru(C_2O_4)3]{\cdot}4H_2O$ towards the oxidation of benzyl alcohol, piperonyl alcohol, benzaldehyde and benzyl amine at room temperature have been studied.
