Interneuron diversity is one of the key factors to hinder understanding the mechanism of cortical neural network functions even with their important roles. We characterized inhibitory interneurons in layer II/III of the rat primary visual cortex, using patch-clamp recording and confocal reconstruction, and classified inhibitory interneurons into fast spiking (FS), late spiking (LS), burst spiking (BS), and regular spiking non-pyramidal (RSNP) neurons according to their electrophysiological characteristics. Global parameters to identify inhibitory interneurons were resting membrane potential (>-70 mV) and action potential (AP) width (<0.9 msec at half amplitude). FS could be differentiated from LS, based on smaller amplitude of the AP (<∼50 mV) and shorter peak-to-trough time (P-T time) of the afterhyperpolarization (<4 msec). In addition to the shorter AP width, RSNP had the higher input resistance (>200 $M{Omega}$) and the shorter P-T time (<20 msec) than those of regular spiking pyramidal neurons. Confocal reconstruction of recorded cells revealed characteristic morphology of each subtype of inhibitory interneurons. Thus, our results provide at least four subtypes of inhibitory interneurons in layer II/III of the rat primary visual cortex and a classification scheme of inhibitory interneurons.

We prove that if a $weak^*$-measurable function f defined on a finite measure space into a dual Banach space is separable-like, then for every measurable set E, the $weak^*$ core of f over E is the $weak^*$ convex closed hull of the $weak^*$ essential range of f over E.

The purpose of this study was to compare the dietary habit and nutrient intakes of Korean farmers according to their different family patterns and farming types. Food and nutrient intakes were obtained by food frequency method. The subjects(male 35%, female 65% : mean age, $48{\pm}11 years)$ were compared 46% of nuclear family, 59% of 3-4 person of family size ; 50% of middle-scale farming ; 54% of rice farming. Sixteen percent were over 60 years old group. In aspects of dietary habit, farmers of medium size farming and 10-20 years of farming experience frequently skipped meals. But their appetite was better than small farm famers. Dinner irregularity was more frequent in their group of 3-4 person families. The numbers of food intake were significantly different according to family pattern. Nuclear family groups consumed more kinds of foods. The mean energy intake was 2000Kcal/day, with PFC ratio of 19 : 16 : 65. The energy and nutrient intakes showed the same tendency as the food variety. Intakes of calcium and iron were lower than the Korean RDA. Families with over 5 people consumed higher amounts of protein and minerals. Intakes of thiamin, niacin, and vitamin E were better in large families and large-scale farming groups. As compared with the PMS ratio, the level of monounsaturated fatty acids as higher than saturated FA. The lipid intake was also better in large families and large-scale farming. The results suggest that dietary habit and nutrient intakes were different by family pattern and farming types.

<P><I>Actinobacillus succinogenes</I>, which is known to produce large amounts of succinate during fermentation of hexoses, was able to grow on C<SUB>4</SUB>-dicarboxylates such as fumarate under aerobic and anaerobic conditions. Anaerobic growth on fumarate was stimulated by glycerol and the major product was succinate, indicating the involvement of fumarate respiration similar to succinate production from glucose. The aerobic growth on C<SUB>4</SUB>-dicarboxylates and the transport proteins involved were studied. Fumarate was oxidized to acetate. The genome of <I>A. succinogenes</I> encodes six proteins with similarity to secondary C<SUB>4</SUB>-dicarboxylate transporters, including transporters of the Dcu (C<SUB>4</SUB>-dicarboxylate uptake), DcuC (C<SUB>4</SUB>-dicarboxylate uptake C), DASS (divalent anion : sodium symporter) and TDT (tellurite resistance dicarboxylate transporter) family. From the cloned genes, Asuc_0304 of the DASS family protein was able to restore aerobic growth on C<SUB>4</SUB>-dicarboxylates in a C<SUB>4</SUB>-dicarboxylate-transport-negative <I>Escherichia coli</I> strain. The strain regained succinate or fumarate uptake, which was dependent on the electrochemical proton potential and the presence of Na<SUP>+</SUP>. The transport had an optimum pH ~7, indicating transport of the dianionic C<SUB>4</SUB>-dicarboxylates. Transport competition experiments suggested substrate specificity for fumarate and succinate. The transport characteristics for C<SUB>4</SUB>-dicarboxylate uptake by cells of aerobically grown <I>A. succinogenes</I> were similar to those of Asuc_0304 expressed in <I>E. coli</I>, suggesting that Asuc_0304 has an important role in aerobic fumarate uptake in <I>A. succinogenes</I>. Asuc_0304 has sequence similarity to bacterial Na<SUP>+</SUP>-dicarboxylate cotransporters and contains the carboxylate-binding signature. Asuc_0304 was named SdcA (<U>s</U>odium-coupled C<SUB>4</SUB>-<U>d</U>i<U>c</U>arboxylate transporter from <I><U>A</U></I>. <I>succinogenes</I>).</P>

<P>Automated irrigation systems based on soil moisture sensor measurements can reduce water and fertilizer use while adequately meeting plant water requirements. In this study, the effects of substrate volumetric water content (θ, v/v) on the flowering of 17-month-old <I>Doritaenopsis</I> Queen Beer ‘Mantefon’ (from the time of deflasking) were examined. The plants were transplanted in plastic pots (10.5 cm width × 9.5 cm height) filled with sphagnum moss and the θ of sphagnum moss was maintained at 0.2, 0.3, 0.4, or 0.5 m<SUP>3</SUP>·m<SUP>−3</SUP> using an automated drip irrigation system. Plants grown at a θ threshold of 0.2 m<SUP>3</SUP>·m<SUP>−3</SUP> had thinner leaves and lower SPAD value than those grown at higher θ thresholds. The net CO2 uptake of the uppermost fully expanded leaf increased with increasing θ between 0.2 and 0.4 m<SUP>3</SUP>·m<SUP>−3</SUP>, but there was no significant difference in the net CO2 uptake between plants grown at 0.4 and 0.5 m<SUP>3</SUP>·m<SUP>−3</SUP> thresholds. The number of flower buds at the time of the first open flower was lower in plants grown at θ thresholds of 0.2 and 0.3 m<SUP>3</SUP>·m<SUP>−3</SUP> as compared with that in the plants grown at 0.4 and 0.5 m<SUP>3</SUP>·m<SUP>−3</SUP> thresholds. Early flower abscission, flower bud dropping, and flower senescence during the 2 weeks after flowering occurred in 55% and 30% of the plants at 0.2 and 0.3 m<SUP>3</SUP>·m<SUP>−3</SUP> thresholds, respectively, whereas plants at θ thresholds of 0.4 and 0.5 m<SUP>3</SUP>·m<SUP>−3</SUP> had negligible flower abscission. Although vegetative growth parameters were similar among θ thresholds of 0.3 m<SUP>3</SUP>·m<SUP>−3</SUP> or higher, plants grown at a θ threshold of 0.3 m<SUP>3</SUP>·m<SUP>−3</SUP> produced fewer flowers than those grown at 0.4 and 0.5 m<SUP>3</SUP>·m<SUP>−3</SUP> thresholds. During the 83-day experimental period, the system irrigated the plants ≈0.79, 1.93, 2.46, and 2.84 L/pot at θ thresholds of 0.2, 0.3, 0.4, and 0.5 m<SUP>3</SUP>·m<SUP>−3</SUP>, respectively. Overall, 0.4 m<SUP>3</SUP>·m<SUP>−3</SUP> was considered to be an optimal threshold θ level for producing high-quality <I>Doritaenopsis</I> Queen Beer ‘Mantefon’ during the flowering period with most efficient water use.</P>

The purpose of this study was to compare dietary behavior and food intake in relation to physical complaints, such as farmer' syndrome(FS) and gastro-intestinal(GI) problem among Korean farmers. The questionnaire was composed of 24 Cornell Medical Index (CMI), 8 farmers' syndrome, and 5 GI problem questions. Food intake data was gathered by the semi-quantitative food frequency method. The subjects(male 226, female 415) who had FS and Gi problem were 12./8% and 8.3%, respectively. The physical complaints were higher in female and the elderly group. In the FS group, lower activity was seen that in normal groups. The lower health status and fatigues were found in the physical complaint groups. Dietary behavior showed low appetite in the physical complaint group, irregular lunch in FS, and irregular breakfast in GI problem group. Changes in dietary behavior were shown in the aspects of lower amount of intake quantity(40.8%), lower consumption in fat(32.8%) and salty(38.8%) foods, and diverse food items(47.8%). Quantity of food consumed was significantly different withing groups with FS. Kinds of food consumed, intake of protein source foods, milk and calcium and total animal foods were lower in the FS group. But milk and calcium source food and all animal food intakes were higher in the GID problem group. The results suggest that dietary behavior and food intake differ within the group of physical complaints.
