This research aimed to analyze the quality of center-based infant/toddler programs in Korea. Scale for infant and toddler programs divide accreditation standards into 4 areas(physical environment, curriculum, health care, management system) with 60 standards. Standards can be divided into basic criteria and general criteria. The subjects are 149 day care centers(44 infant day care centers and 105 day care centers), and raters(teachers or principal) assessed the quality of each item on a 5-point Likert scale. The results of this study are as follows: 1) Self-evaluation result have marked 3.67 as average(range : 2.32~4.90), which barely meets basic criteria level. 2) Physical environment area has received worst score(3.41) and Health care area has received best score(3.92). 3) Each standard's score indicate the quality of infant/toddler care program: Feed care(4.29), Affectionate teacher-infant interaction(4.14) were highly rated while Nature environment/anmal/plant(2.75) and Teacher's facilities(2.74) were rated low. 4) Some variation factors showed differences in the qualitative level; number of child, education level of principal.

Ripe fruit of pepper (Capsicum annuum) showed resistance to Colletotrichum gloeoporioides, but unripe fruit was susceptible. We previously isolated the PepTLP gene that induced in both unripe and ripe fruit by fungal infection and wound, and only in ripe fruit by jasmonic acid (JA) treatment. To examine further regulation of PepTLP, the action of specific agonist and antagonists of known signaling effector on the .PepTLP expression by fungal infection, wound, and JA was investigated. A similar dephosphorylation event negatively activated all the PepTLP expression in the ripe fruit by fungal infection, wound, and JA. The induction of PepTLP expression by wound is differentially regulated via phosphorylation and dephosphorylation step during pre- and post-ripening, respectively. In addition, the induction of PepTLP expression in the ripe fruit by wound and JA is differentially regulated via dephosphorylation and phosphorylation step, respectively. Only both wound and JA treatment has synergistic effect on the PepTLP expression in the unripe fruit. Both SA and JA treatments on the unripe fruit, and both wound or JA and SA on the ripe fruit could not do any effect on the expression of PepTLP. These results suggest that the induction of PepTLP expression is differentially regulated via complex regulatory system against fungal infection, wound, and JA treatment during pre- and post-ripening of pepper fruit.

Liquefied Natural Gas(LNG) continues to attract modern gas industries as well as domestic markets as their main energy source in the recent years. This is mainly because LNG is inherently cleaner and more energy efficiency than other fuels. Offshore LNG production plant is of interest to many oil producing companies all over the world. This article discuss about the production process encountered while developing such a production facility. Typical offshore oil and gas processing required for oil stabilization and other optional units that can be added to the facilities. The production process can broadly be divided into five major units namely, (i) Oil Stabilization unit, (ii) Gas Treatment unit, (iii) Methane Recovery unit, (iv) Distillation unit and (v) LNG Liquefaction unit. The process simulation was carried out for each unit with a given wellhead composition. The topside facilities of offshore LNG production plant will be very similar to the process adopted in offshore processing platform along with the typical onshore LNG production plant. However, the process design problems associated with FPSO motion to be taken care of while developing floating LNG production plant.

Objectives : This study was intended to reveal the chemical profiles of aerial(leaf, stem) and underground(rhizome, radix) parts of wild ginseng, and to investigate their anti-aging effects on human skin cells. Methods : Wild ginseng, estimated for over 20 years, was divided into the aerial and underground parts. Total phenolic contents of each extracts were measured using a Folin-ciocalteu method. The contents of 18 amino acids, 8 minerals and 27 ginsenosides were determined by GC-FID, ICP-MS and LC-MS, respectively. The anti-aging effects, including the radical scavenging activity, the activation of mitochondrial function on human fibroblasts, and the proliferation activity on human keratinocyte progenitor cells, for the whole plant and underground part of wild ginseng were evaluated. Results : The total phenolic acids, amino acids, and minerals in the aerial part were more than twice as high as in the underground part. Compared to the cultivated ginseng root, there were various types of ginsenosides in both parts of wild ginseng, and the total amount was more than twice as high. In particular, the aerial part significantly contained ginsenoside F1, F2, C-Mc1, and C-O, and the distinctive patterns that distinguish each parts of wild ginseng from the cultivated ginseng root were derived. The whole plant and underground part of wild ginseng exhibited significant antioxidant effect(14.3-45.6%), activation of mitochondrial membrane potential(105.5-120.1%), and cell proliferation(112.1-125.4%). Conclusions : The entire plant and underground part of wild ginseng are high value-added plants and have beneficial effects on skin anti-aging properties through its abundant metabolites.

Advanced Pressurized Reactor 1400(APR1400), which is a standard evolutionary advanced light water reactor(ALWR), has been developed from 1992 as one of long-term Government Project(G-7). The APR-1400 is designed to operate at the rated output of 4000MWt to produce an electric power output of around 1450MWe. Due to the increased electric power, In Nuclear Power plant huge quantities of heat are generated in the thermo-dynamic process used for producing electrical energy. So, There is considerationly additional cooling, Heat transfer area and increased cooling water of Heat Exchanger which take care of the different smaller cooling duties within the nuclear power plant. We review applying to PRE instead of Shell-and-Tube Heat exchanger. In this paper, we describe the major design features of PRE, Comparison between a PHE and a Shell-and-Tube Heat Exchanger, and then Applicability of Plate Heat Exchanger in Nuclear Power Plant Component Cooling water systems.
