The purpose of this study was to evaluate the effects of container types on seedling growth of Betula costata, Liriodendron tulipifera, Fraxinus rhynchophylla, Fraxinus mandshurica, Zelkova serrata, and Ulmus parvifolia in the container nursery system. We used three container types [20 cavities (150 seedlings/$m^2$-400 mL), 24 cavities (200 seedlings/$m^2$-320 mL), and 35 cavities (260 seedlings/$m^2$-240 mL)] and measured root collar diameter (RCD), height, biomass, seedling quality index (SQI), and root density. The root collar diameter, height, biomass, SQI, and root density of seedlings were the highest at 20 cavities/tray in all six species because this container type has the largest volume and lowest seedling density. However, F. rhynchophylla growth at both 20 and 24 cavities/tray, Z. serrata growth at both 24 and 35 cavities/tray and B. costata growth at all sizes were not significantly different. As expected, container volume was positively correlated with RCD, height, and biomass of five species except for Z. serrata, but seedling density negatively did. Based on these results, 20 cavities/tray are optimal for L. tulipifera, F. mandshurica, and U. parvifolia, 20 or 24 cavities/tray for F. rhynchophylla, 24 or 35 cavities/tray for Z. serrata, and 35 cavities/tray for B. costata, respectively. Usage of optimal container will make us get good quality seedlings as well as reduction of production costs in the container nursery.

우리의 뇌가 위치한 머리에도 많은 경락이 흐르고 중요한 혈자리들이 자리잡고 있다. 뇌호흡을 잘 하기 위해서는 머리에 있는 혈로 숨쉬는 법을 익히는 것이 중요하다. 머리혈로 숨쉬기는 짧은 시간에 기운을 많이 받을 수 있는 아주 기초적인 수련법이다. 그러기 위해서는 우선 머리의 혈자리 이름을 외워두고 정확한 위치를 알아두는 것이 의식을 집중하는데 도움이 된다.

Purpose : Arterial blood gas analysis is frequently performed in neonatal intensive care unit (NICU) to evaluate ventilation and the metabolic state of critically ill infants. In occasions when umbilical arterial catheterization is not available, frequent arterial puncture is mandatory. This requires some technical skill and may occasionally have side effects. So we studied the validity of capillary blood gas analysis which can be performed conveniently compared with arterial blood. Methods : Twenty-four neonates admitted to NICU during April to Aug. 2001 were studied. They were more than two weeks old without indwelling arterial catheters. Thirty-six times, simultaneous arterial, and capillary blood gases were drawn by puncture and the pH, $pCO_2$ and $pO_2$ of each sample was measured. Blood pressure and body temperature was checked before sampling to rule out impaired peripheral circulation. Capillary blood was collected from warmed heels. Results : There was a strong correlation between capillary and arterial pH(r=0.91, P<0.05). The absolute value of the difference between arterial and capillary pH was less than 0.05. Also capillary $pCO_2$ showed correlation with arterial $pCO_2$(r=0.77, P<0.05). Despite a statistically significant correlation between capillary and arterial $pO_2$(r=0.68, P<0.05), the absolute value of the difference was more than 10 mmHg in 92% of cases. Conclusion : Capillary blood gases accurately reflected arterial pH and $pCO_2$ and showed a relative correlation with $pO_2$. Capillary blood gas analysis can be a useful alternative to arterial blood when continuation of the umbilical arterial catheter is no longer available.

Weathering hollows which develop on various rocks are the terrain whose lithological characteristics and formation of the bed rock is under active discussion. The shore in Dapyeong-ri, Sacheon-si has alternation of strata of pelite and sandstone, and the weathering hollows develop on the shore platform and the sea cliff where sandstone is exposed. To analyze the development characteristics of weathering hollows by development of joints, interpenetration of veins and physical and chemical features of the stone, the study conducted a topographic investigation, XRD analysis and an observation using a polarizing microscope. As the result of the investigation and analysis, tafoni and gnamma are spread in the same area and new tafoni is being formed as the existing weathering hollows are destroyed by the expansion and growth of the joint. The vein, which was found to be a quartz vein, may accelerate the development of weathering hollows combining with the joint but may also hamper their growth if the veins are penetrating perpendicularly. It is generally known that weathering hollows develop regardless of the type of rocks, however, the analysis on the lithological features show that the development is limited on the fractured and broken rocks.

This study aimed to compare effectiveness of fluorescent reagents for enhancing blood such as acid yellow 7, rhodamine 6G, eosin Y. AY7 and eosin Y have been introduced in Korea as fluorescent reagents for enhancing blood, but not rhodamine 6G. In this study, researchers photographed when each reagents gave the most effective results. Consequently, rhodamine 6G was superior to the others. Eosin Y enhanced bloody fingermarks weakly compared to AY7 and rhodamine 6G. Furthermore, the more depletion trials were done, the less effectiveness were shown. Therefore, researchers recommended that crime scene investigators try to use rhodamine 6G fluorescent reagents for enhancing blood.

Purpose : Although neonatal pulmonary hemorrhage is rare, it is associated with high mortality. We aimed to evaluate the risk factors associated with pulmonary hemorrhage in preterm infants and to describe the clinical course, including neonatal morbidity, of infants who developed pulmonary hemorrhage. Methods : We performed a retrospective case-control study of 117 newborn infants aged less than 37 gestational weeks admitted to the neonatal intensive care unit of Daegu Fatima Hospital between January 1995 and December 2008. Control group infants without pulmonary hemorrhage were matched according to the gestational age, duration of mechanical ventilation, and birth weight range (${\leq}100g$). Pulmonary hemorrhage was defined as the presence of hemorrhagic fluid in the trachea and severe respiratory decompensation. Results : Pulmonary hemorrhage occurred in 17 cases of very low birth weight infants (VLBW; birth weight < 1,500 g; median age, 3 days) and 22 cases of low birth weight infants (LBW; $1,500g{\leq}$ birth weight < 2,500 g; median age, 1 day). Antenatal maternal glucocorticoid treatment significantly reduced the incidence of pulmonary hemorrhage in VLBW infants. Low APGAR score (${\leq}3$ at 1 min) and acidosis at birth were associated with significantly high incidence of pulmonary hemorrhage in LBW infants. Conclusion : Antecedent factors and timing of pulmonary hemorrhage of LBW infants were different from those of VLBW infants. The mortality rates of VLBW and LBW infants were 88.2% and 45.5%, respectively. Pulmonary hemorrhage was the principal cause of death in 66.6% VLBW infants and 40.0% LBW infants.

In this study, functionality of products of silkworm hemolymph fermented by Bacillus species was studied such as cell viability, antioxidant effect, and inhibitory effect on tyrosinase activities. A matured silkworm hemolymph was degraded by fermentation with Bacillus subtilis 10854 and Bacillus amyloliquefaciens M27. Especially, proteins of matured silkworm hemolymph were degraded to 3,000 Da by fermentation with B. amyloliquefaciens M27. Cell viability for MTT assay was higher than PBS in hemolymph and fermented hemolymph. A DPPH free radical scavenging activity of fermented hemolymph was as higher as Vitamin C and dependent on sample concentrations. Thus, these results suggest that degraded hemolymph fermented by B. amyloliquefaciens M27 may have antioxidant properties as a material for cosmetics.

Lueco-crystal violet(LCV) is a very effective reagent used to enhance bloodstain. However, when the LCV is treated to the bloody fingerprint, the bubbling occurs, so that the minutiae and features of the fingerprint can be damaged. In this study, we studied a method to reduce the bubbling of LCV. As a result, the most effective method for reduction bubbling and enhancement bloodstain was to treat ethanol-based aminotriazole(AT) solution before LCV treatment.
