  • During our previous studies on the relationship between nutrient requirements of S. hygroscopicus C9 and rapamycin biosynthesis, we developed chemically-defined media containing among other nutrients, aspartic acid, arginine, histidine, or ammonium sulfate. However, these media (“Cheng et al. medium” and “Lee et al. medium”) showed very slow growth characterized by a very long lag phase of growth. In an attempt to develop a chemically-defined or semi-defined medium to support more rapid growth and increased cell production, we have carried out studies to shorten the lag phase. Of the various additives tested, vitamin-free casein acid hydrolysate was the most significant by shortening the lag phase by 2-3 days. Mixtures of amino acids failed to replace casein acid hydrolysate. The active principle passed through an ultrafilter with a molecular weight cutoff of 1,000 and thus may be a peptide. The present work has yielded a semi-defined medium which should be useful for further growth studies on S. hygroscopicus C9.

  • The export is an important economic growth strategy in South Korea. South Korea is strongly dependant on external trades. Bilateral trade between China and South Korea has been grown rapidly in recent years. The China is now Korea's first-largest trading partner. Thus, the Korea-China Free Trade Agrement (FTA) in South Korea's trade operations is very important. A discussion of Korea-China bilateral FTA commenced in 2004 November. This paper is to recognize the phenomenon of major issued fields in the Korea-China FTA such as a manufacturing, agriculture, customs and seek a negotiation strategy that are summarized as follows. In terms of trade based on manufacturing, it is necessary to divide into a private, general reduction and priority reduction item to recognize whether it is complementary or competitive on the specific industry in the FTA negotiation by using an index regarding supplement and competition of these two countries. In particularly sensitive agricultural field, FTA should be progressed gradually after giving a certain period of time of grace period on the basis of various flexible tariff systems in order to minimize agriculture damage as a result of the rapid growth from import of Chinese agricultural goods.

  • This study investigates the effect of shareholders' rights, disclosure, and transparency on firm value. This study also investigates whether corporate social responsibility (CSR) is pure moderation or quasi moderation in the effect of shareholders' rights, disclosure, and transparency on firm value. This study's novelty is building a model framework to increase firm value and the role of CSR in increasing firm value. This study used secondary data provided by Indonesia, Malaysia, and Thailand Stock Exchanges. The sample of this study is 142 companies with four years of observations from 2012-2015. Firm value is measured by Tobin's Q. While shareholder's rights, disclosure, and transparency are measured using the ASEAN scorecard. The analysis method used in this study is a fixed effect model using a panel data approach. The result of this study shows that shareholders' rights have a significant positive effect on firm value. However, disclosure and transparency do not affect firm value significantly. In comparison, the CSR disclosure has a moderation effect on the relationship between shareholders' rights and firm value. The CSR disclosure does not have a moderation effect on the relationship between disclosure and transparency and firm value.

  • Even though gratitude is considered as an important virtue to possess for successful adulthood, little is known about what cultivates gratitude and its benefits associated with psychological well-being among adolescents. By examining gratitude as a daily mood, this study asked (1) whether adolescents' daily grateful mood varied as a function of daily parental emotional support and (2) whether adolescents' psychological well-being varied as a function of daily grateful mood within person across seven days. The sample consisted of 70 adolescents in 8th grade recruited from a public middle school. Participants completed daily diary checklists online each evening for seven days. On days when adolescents perceived greater parental emotional support from mother or father than they typically did during the week, they rated their grateful mood to be higher than other days. With more emotional support from father, adolescents reported more grateful mood not only on that day, but also the following day. While this result highlights the important role that parents play in adolescents' experience of grateful mood, emotionally supportive behaviors of fathers appear particularly promising for cultivating gratitude. Further, daily grateful mood on a given day accounted for the significant variance in adolescents' psychological well-being not only on the same day, but also the following day. Research and practical implications of the results are discussed.

  • The thermal, mechanical, and neutronic performance of the metal alloy fast reactor fuel design complements the safety advantages of the liquid metal cooling and the pool-type primary system. Together, these features provide large safety margins in both normal operating modes and for a wide range of postulated accidents. In particular, they maximize the measures of safety associated with inherent reactor response to unprotected, doublefault accidents, and to minimize risk to the public and plant investment. High thermal conductivity and high gap conductance play the most significant role in safety advantages of the metallic fuel, resulting in a flatter radial temperature profile within the pin and much lower normal operation and transient temperatures in comparison to oxide fuel. Despite the big difference in melting point, both oxide and metal fuels have a relatively similar margin to melting during postulated accidents. When the metal fuel cladding fails, it typically occurs below the coolant boiling point and the damaged fuel pins remain coolable. Metal fuel is compatible with sodium coolant, eliminating the potential of energetic fuel-coolant reactions and flow blockages. All these, and the low retained heat leading to a longer grace period for operator action, are significant contributing factors to the inherently benign response of metallic fuel to postulated accidents. This paper summarizes the past analytical and experimental results obtained in past sodium-cooled fast reactor safety programs in the United States, and presents an overview of fuel safety performance as observed in laboratory and in-pile tests.
