  • Energy obtained by grazing cattle in oil palm plantations is usually used for maintenance of body functions, the construction of body tissues and pregnancy, the synthesis of milk and the conversion to mechanical energy used for activities such as walking, eating and others. In this study, attempt was made to estimate metabolizable energy (ME) requirement of grazing cattle. Models of ME requirement (MER) for maintenance, gain, pregnancy, lactation and activities were developed. ME system and units were used because of wide recognition. Estimation of ME intake in grazing cattle was expressed as MEVI = $14.58{\times}VI{\times}DMD$, and under grazing condition MEVI = $MER_i$. MER was expressed as a function of net energy(NER, MJ) required for the i'th body function. Coefficient of efficiency for conversion of ME into net energy(ki) was adopted from literatures. Quantifying of ME requirement for Kedah-Kelantan cattle under grazing condition was made by using equation MERM = NEM / kn. The estimated values of MER for Kedah-Kelantan cattle is quite reasonable if compared with other estimates as reported in literatures from stall-fed animals. Dynamic MER models for grazing herd was developed in order to estimate ME requirement for maintenance and productions. These ME requirement models can be used for prediction of energy utilization pattern of the herd in the grazing systems.

  • Melittin (ME), a linear 26-residue non-cell-selective antimicrobial peptide, displays strong lytic activity against bacterial and human red blood cells. To design ME analogue with improved cell selectivity, we synthesized a melittin diastereomer (ME-D) with D-amino acid in the leucine zipper sequence (Leu-6, Lue-13 and Ile-20). Compared to ME, ME-D exhibited the same or 2-fold higher antibacterial activity but 8-fold less hemolytic activity. Circular dichroism analysis revealed that ME-D has much less $\alpha$-helical content in $\alpha$-helical content in the presence of zwitterionic EYPC/cholesterol (10 : 1, w/w) liposomes compared to negatively charged EYPE/EYPG (7 : 3, w/w) liposomes. The blue shift of the fluorescence emission maximum of ME-D in zwitterionic EYPC/cholesterol (10 : 1, w/w) liposomes was much smaller than in negatively charged EYPE/EYPG (7 : 3, w/w) liposomes. These results suggested that the improvement in therapeutic index/cell selectivity of ME-D is correlated with its less permeability to zwitterionic membranes.

  • This study researchers the libretto and the original novel of the opera to propose fashion styles and stage costumes for the opera, "La $boh\grave{e}me$." This article studied the meanings of the $boh\grave{e}me$ in the 1830's France and the characteristics of the $boh\grave{e}me$ that appeared in the original novel, "$Sc\grave{e}nes$ de la vie de $boh\grave{e}me$." The characteristics of bohemian fashion styles in the $Sc\grave{e}nes$ de la vie de $boh\grave{e}me$ were not normal, not related with trends, and not new. Before presenting the new fashion styles, this study examined the stage costume problems of La $boh\grave{e}me$ with five existing performance materials. In conclusion, this study proposed new stage costume designs that reflect more dramatic fashion expressions of the characters, expression on the passage of time, and contemporary fashion records.

  • J2ME mobile programs have been widely used as mobile devices like mobile phones become popular. Efficient use of resources in mobile programs is very important because mobile programs are executed in mobile environment with insufficient resources. Moreover, most J2ME programs are event-driven, so effective event handling is important for reliability and efficient use of resource. In this research, we develop a dynamic event analysis system, which can show event handling in real-time. In this system, users can trace only interesting events by selecting some options, and can get event profile after execution.

  • This study was conducted on wine consumers to explore their behavioral characteristics concerning their drinking frequency of wine, wine selection factors, and difficulties in selecting wines. Data were collected during February 19th 2014 to April 20th 2014. Respondents were students who were taking classes about wine at a University located in the Gyeonggi-do area. Prior to the analysis, wine consumers were classified based on frequency of consumption: those who consumed wine less than once a month were classified as "Tell me consumers", whereas those who consumed wine once or more a month were classified as "Engage me consumers." The wine selection factors of the two groups were as follows: 'label aspect', 'taste and aroma', 'use purpose', and 'price and recommendation'. Regarding 'label aspect' and 'use purpose', there were significant differences between the two groups. Regarding difficulties in selecting wines, "Tell me consumers" mentioned the following: 'experience', 'price', and 'food pairing'. "Engage me consumers" mentioned the following: 'ability to identify new wines' and 'tastes of others who drink with or oneself'. Classifying domestic wine consumers and their behavioral features of drinking frequency of wine can be used for market segmentation of wine consumers.

  • The reaction rates of 4-X-2,6-dinitrochlorobenzenes (X = $NO_2$, CN, $CF_3$) with Y-substituted benzylamines (Y = p-$OCH_3$, p-$CH_3$, H, p-Cl) in MeOH-MeCN mixtures were measured by conductometry at $25^{\circ}C$. It was observed that the rate constant increased in the order of X = $NO_2$ > CN > $CF_3$ and in the order of Y = p-$OCH_3$ > p-$CH_3$ > H > p-Cl. When the solvent composition was varied, the rate constant increased in the order of 100% MeOH < 50% (v/v) MeOH-MeCN < 100% MeCN. These results may be ascribed to the formation of hydrogen bonds between the alcoholic hydrogen and nitrogen of benzylamines in groud state (GS). We conclude that the reaction takes place via $S_NAr$ base on the transition state parameters ${\rho}x$, ${\rho}Y$, $\beta_{nuc}$, and solvent effects.

  • The solvolysis of substitued phenacyl tosylates was studied in binary solvent mixtures of methanol-acetonitrile and methanol-acetone at 55$^{\circ}C$. Except for m-nitrophenacyl tosylate, the rate constants were increased with both of electron-donating substituents and electron-withdrawing ones and its rate constants were the largest in the binary solvent mixtures of 90% MeOH-10% MeCN. The results show that the reactions were changed with dissociative $S_N2$ mechanism judging from the magnitude of 1/m values going from the electron-withdrawing group to the electron-donating one of the substrate. And above results were consisted with the account for the PES model and QM approach.

  • Emission of methyl bromide (MeBr) from soil was implicated in stratospheric ozone depletion. To determine multi analysis of alternatives fumigants for MeBr, this paper describes the methods of analysis in water and soil. The MeBr, methyl iodide (Mel), propargyl bromide (PBr), cis 1,3-dichloropropene (cis 1,3-D), trans 1,3-dichloropropene (trans 1,3-D) and chloropicrin(CP) are separated on the base line on GC-ECD at three column of AT+DB+DB (90m) with temperature programing of $35^{\circ}C{\rightarrow}110^{\circ}C$ on GC-ECD. The relative retention time for MeBr, Mel, PBr, cis 1,3-D, trans 1,3-D and CP is 1.0, 1.4, 2.3, 3.2, 3.6 and 3.7, respertively. The detection limit for MeBr, Mel, PBr, cis 1,3-D, trans 1,3-D and CP is 469 pg, 5 pg, 21 pg, 79 pg, 101 PE and 5pg, respectively. Recovery of MeBr Mel, PBr, cis 1,3-D, trans 1,3-D and CP in water added 150 ppm fumigants were 81%, 96%, 95%, 97%, 98% and 99%, respectively. Recovery of MeBr, MeI, PBr, cis 1, 3-D, trans 1,3-D and CP in soil added 150ppm fumigants were 56%, 84%), 85%, 81%, 87% and 88%, respectively.

  • This paper proposes a magnetoelectric (ME) composite transducer structure consisting of a magnetostrictive H-type Fe-Ni fork substrate and piezoelectric PZT plates. The fork composite structure has a higher ME voltage coefficient compared to other ME composite structures due to the higher quality (Q) factor. The ME sensitivity of the fork structure reaches 12 V/Oe (i.e., 150 V/cm Oe). The fork composite with two PZT plates electrically connected in series exhibits over 5 times higher ME voltage coefficient than the output of the rectangle structure in the same size. The experiment shows the composite of a Fe-Ni fork substrate and PZT plates has a significantly enhanced ME voltage coefficient and a higher ME sensitivity relative to the prior sandwiched composite laminates. By the use of a lock-in amplifier with 10 nV resolution, this transducer can detect a weak magnetic field of less than $10^{-12}$ T. This transducer can also be designed for a magnetoelectric energy harvester due to its passive high-efficiency ME energy conversion.

  • Purpose : The purpose of this study was to investigate the coincidence between keywords of Journal of the Korean Society of Physical Medicine (JKSPM) and MeSH terms, a controlled vocabulary used in MEDLINE. Methods : A total of 838 keywords used in 252 papers of JKSPM from Vol.1, No.1, 2006 to Vol.7, No.1, 2012 were compared with MeSH terms. All of keywords are classified to three large categories; complete coincidence, incomplete coincidence, and complete incoincidence. Results : The keywords in complete coincidence category were 183(21.8%), the keywords in incomplete coincidence category were 378(45.1%), and the keywords in complete incoincidence category were 277(33%). The most used keyword in complete coincidence category was 'stroke' and in complete incoincidence category was 'balance'. The most used keyword matching entry terms in incomplete coincidence category was 'elderly'. Conclusion : The rate of complete coincidene of keywords with MeSH terms was not higher than the rates of incomplete coincidence and complete incoincidence. It is necessary to understand MeSH terms more accurately and specifically. The JKSPM should ask the authors to use MeSH terms as keyword when they submit the paper.
