<P>This study aimed to investigate the quality of fresh noodles prepared using insoluble dietary fiber-enriched fractions (IEF) recovered from kimchi by-products (KBP) and common wheat flour, instead of semolina. Four samples (NICO, NIC2, NIC4, and NIC6) were prepared using common wheat flour mixed with different ratios of IEF (0 g/100 g; 2 g/100 g; 4 g/100 g; 6 g/100 g, respectively); Semolina pasta (SMP) was prepared as control. With increasing IEF ratios, cooking loss and swelling indexes increased significantly (p < 0.05). SEM images showed continuous and clear air pockets that were observed in NIC2 and SMP, whereas a loose protein network and big air pockets were observed in NIC4 and NIC6. After addition of IEF, L*, a*, and b* of samples decreased in all samples. Hardness of all samples in TPA was not statistically different regardless of the addition of IEF to common wheat flour. NIC2 showed the highest overall acceptability in sensory evaluation, while hardness, texture, color, taste, and flavor decreased in higher than 2 g/100 g (p < 0.05) IEF. Based on these results, fresh noodle using 2 g/100 g IEF from KBP and common wheat flour showed a great possibility to replace semolina pasta. (C) 2017 Elsevier Ltd. All rights reserved.</P>

In order to determine the changes in pH, water holding capacity(WHC) and tenderness of chicken meat during the postmortem storage, the breast and leg muscles were obtained from Rhode Island Red Chicken of 2, 6 and 18 months old send stored at 4℃ for 7 days postmortem. The results obtained were as follows: 1) The pH was not significantly affected by the difference of muscle position and chicken ages. However, the pH was rapidly decreased in the early storage period up to 8 hours afterslaughtering, but this trend was reversed at 48 hrs and the pH change was not recognized from 48 hours up to 168 hours of postmortem storage. 2) The WHG of the muscles of 2-month chicken was significanttly higher than that . of 18-month chicken. The WHC was not affected by the muscle positions but storage period caused considerable changes in the WHC up to 8 hours postslaughtering. 3) The tenderness of the muscles of 18-month chicken was significantly lower than that of 2-, and 6-month chicken. The tenderness was not significantly different between muscle positions but significantly decreased up to 8 hours postslaughtering and increased gradually thereafter.

<P>The chemical and ultrastructural properties of cell walls were investigated to determine the effect of dilute acid pretreatment on the hydrolysis of lignocellulosic biomass. Confocal Raman microscopy was used to gain a clear understanding of how dilute acid pretreatments destroy lignocellulosic cell walls. Total fermentable sugar (glucose and xylose) was high in oxalic acid hydrolysate (26.18 g/L) compared to that in sulfuric acid hydrolysate (24.34 g/L). Chemical composition of the pretreated biomass differed slightly according to the acid catalyst used. Oxalic acid pretreatment was effective for enzymatic hydrolysis, with 29.46 g/L of total fermentable sugar after 96 h. Optical microscopy showed that dilute acid pretreatment significantly changed cell wall structure, and broken and crushed cell walls could be clearly seen during pretreatment. Based on confocal Raman peak intensity, the ratio of lignin/cellulose [I(1600)/I(900)] was low for oxalic acid-pretreated biomass compared to sulfuric acid-pretreated biomass. (C) 2016 Elsevier Ltd.

Sixteen piston core samples collected from the Heuksan Mud Belt on the southeastern inner shelf of Korea were analyzed to characterize sediment property and distribution in relation to interpreted seismic units. The results from seven of 16 cores are presented in this study using core locations along a seismic track line. Variations in physical properties with depth gradually increased and/or decreased, depending on the characteristics of the specific property. Property patterns are primarily the result of dewatering caused by compaction and/or consolidation. Significant variations in depth are due to differences in sediment texture. In particular, core P03 is largely composed of sandy sediments below 170 cm. All core data come from three specific seismic Units: I, IIa and IIb, in descending order. The seismic patterns that define these units are interpreted as related to the rate of sea-level change during transgressions and depositional processes during the Holocene. Regionally, the variation of physical properties along the seismic profile is likely to reflect the relative characteristics of the seismic units. Unit I is characterized by low shear strength/wet bulk density and high porosity. Unit IIa appears to have higher shear strength than Units I and IIb. Unit IIb shows high wet bulk density and velocity. These observations suggest that the physical properties are mainly controlled by depositional processes related to sea-level change. Clay fabric analysis that uses a scanning electron microscope for two core samples shows the change of particle arrangement due to compaction caused by overburden loading with burial depth. In the upper part of the core, edge-to-edge and edge-to-face contacts dominate. In contrast, face-to-face contact characterized by the well-oriented arrangement of clay particles frequently occurs in the lower parts of the cores, indicating sediment compaction or initial consolidation caused by overburden pressure.

During the autumn of 1990 , we had investigated the clinical featuresw and followed the change in the direct immunofluorescent antibody(IFA) titers in 28 children with scrub typhus who resided in or near Chinju, Korea. All the children except one were diagnosed by the peak IFA titers of 1:160 or higher. The results were as follows: 1) The clinical features of our children were not different, to a large degree, from those of adults ever described in Korea literatures. But the frequence rates of skin rash, eschar and conjunctival injection were higher, those of proteinuria and hematuria were lower than those in adults and the characters of rash in our children were also quite different(faces were frequently the first site of eruption and even palms and soles were involved occasionally, initial bright red color of rash was changed into brown color during the acute phase). 2) IFA titers rose rapidly during the 2nd or 3rd week of illness and then formed plateau. When we suggest IFA titers of 1:180 or higher as the diagnostic criteria, the seropositivity of our children was 5/7(75%) in the 1st week and over 95% in the 2nd through 5th week of illness, and suggest IFA titers of 1:160 or higher,then the seropositivityin the 1st, 2nd and 3rd through 5th week were 3/7(43%), 23/31(74%) and over 95%,respectively. 3) IFA titers in 6-8 months after disease onset were 1:80(13 children) or 1:20( 7 children), and in one and half year (our longest follow-up period), 1:20 (3 children) showing that IFA lasts longer than one and half year after sickness. 4) From the above data (3) and the fact that majority of cases of scrub typhus occur in the autumn season in Korea, IFA titers of 1:40-1:160 should be used as the diagnostic criteria in order to distinguish between the present and past infections.

This experiment was conducted to find out the adequate foliar spraying of PP_333 solution and fertilizer level of soybean. The concentration of the PP_333 solution were two, ficve and eight percent and spraying time was 25th day after seeding. The fertilizer level were three, standard, increasing 50% and 100% more than standard level. The fertilizer application method was basal dressing with total amounts. PP_333 treatment showed shorten_culm length in every plot but decreased capsule No. per plant. This results would be increased lodging resistance from the stormy rain period of flowering time of soybean. But seed yield of soybean decreased compare with check plot because of decreasing of capsule No. per plant. Fertilizer response showed not significant difference on different fertilizer level. Adequate concentration of PP_333 was expected five percent when yield and shorten_culm length of soybean were reasonable.

This study was carried out to study effects of the addition level of acetamide and non-permea-ble cryoprotectants(Ficoll, sucrose) in VS(20% glycerol + 10% ethyleneglycol) and equilibration time on the survival of vitrified mouse morulae. The results are summarized as follows: 1. When 10, 15 and 20% of acetamide were added to the new vitrification solution(20G 10E), FDA-scores of embryos were 4.4(control), 4.4(10%), 3.6(15, 20%), respectively. The addition of acetamide did not affect the survival of forzen-thawed morulae. 2. The survival between 5 min(3.5) and 10 min(4.6), 10 min(4.6) and 20 min(3.2) of equili-bration in 10% sucmse, and 20 min(3.2) and 5 min(4.0), or 10 min(4.3) in 20% sucrose was sig-nificantly different(P<0.05). The highest survival(4.6) was obtained in mouse morulae equilibrat-ed in VS(2OG10E) containing 10% sucrose for 10 minutes. 3. FDA-score of morulae frozen in the new vitrification solution containing 0, 10, 20 and 30% Ficoll was 4.5, 4.2, 4.4 and 4.6, respectively and had no significant effect among concentrations of Ficoll. The development rate after culture(24h) was 89%(20% Ficoll) and 93% (30% Ficoll), respectively.
