Abdominal compartment syndrome (ACS) is a life-threatening disorder caused by rapidly increasing intra-abdominal pressure. ACS can result in multiorgan failure and carries a mortality of 60~70%. The treatment of choice in ACS is surgical decompression. There are very few reports of ACS and experience in Korea. We report 12-year-old male patient who developed an abdominal compartment syndrome due to traffic-accident-induced retroperitoneal hematomas, Which was successfully treated by performing a bedside emergency surgical decompression with open linea alba fasciotomy with intact peritoneum. When patients do not respond to medical therapy, a decompressive laparotomy is the last surgical resort. In patients with severe abdominal compartment syndrome, the use of a linea alba fasciotomy is an effective intervention to lower intra-abdominal hypertension (IAH) without the morbidity of a laparotomy. Use of a linea alba fasciotomy as a first-line intervention before committing to full abdominal decompression in patients with abdominal compartment syndrome improves physiological variables without mortality. Consideration for a linea alba fasciotomy as a bridge before full abdominal decompression needs further evaluation in patients with polytrauma abdominal compartment syndrome.

The purpose of this study was to explore the meaning and essence of experience of family members as care-givers of terminally ill cancer patients at hospice wards. This study was based on the Giorgi phenomenological method, which describes the experiences about the family caregivers. We had in-depth interview with spouses and orthogonal families of nine terminally ill cancer patients. Results were drawn into 13 essential themes, 45 sub themes, and 122 main points. The essential themes are as follows: "cling of life", "bed-keeper", "sacrifice of care", "physical and mental exhaustion during care process","feeling of love and hatred", "avenge on a patient", "self-condemnation", "futility after exhaustion", "consolation of other caregivers", "utmost efforts in resignation", "freedom from suffering", "paradoxical blessing of cancer", "introspected revolution", and "preparation of a dignified death". Implications and limitations are discussed based on study results.

Chemical homogeneity and dispersoid formation in mechanically alloyed Al-Ti composite metal powders were investigated in order to fabricate the high temperature Al-Ti alloys. The homogeneity of composite particles was able to be obtained by MA milling time more than 10 hours with the milling velocity of 400 rpm. The amounts of titanium, carbon and oxygen elements in MA Al-Ti alloys by chemical analysis were 8.2, 1.135 and 0.233 wt.%, respectively. The amount of carbon analyzed corresponds to 90 pet. of carbon contained the PCA of stearic acid. TEM analysis has revealed the presence of the rounded $Al_3Ti$ dispersoids with the size of 250nm and the $Al_4C_3$ dispersoids of cylindrical shape with a size of 50nm in thickness and 150nm in length. Also, the some rounded $Al_2O_3$ dispersoids with a size of about 20nm were found in grain boundaries as well as in matrix.

The use of welding process has been increased for manufacture of machine, bridges, ships, gas facilities and so on together with development of welding technique. Accordingly, it has been needed to develop the welding methods considering higher productivity and safety design for manufacture of their welding structures. In this study, it was studied basically on characteristics of fatigue strength and fatigue life in full penetrated cruciform fillet weld zone in relation to material thickness, welding passes, loading direction and notch radius of toe zone. Most of fatigue failure occurred in toe zone of cruciform fillet weld joint. Fatigue strength and fatigue life are under the influence of stress concentration due to notch radius and flank angle of toe zone. The metal of toe zone annealed and diffused by multi-layer welding and acicular ferrite structure formed by the result improved fatigue strength and fatigue life.

Effects of reaction conditions such as power input and feeding time and feeding mode of reactants on the reaction crystallization of lanthanum oxalate in semi-batch reactor were investigated experimentally. Even though the crystal size distribution of lanthanum oxalate was always monomodal, its mean crystal size was significantly varied with the reaction conditions. As the power input and reactant feeding rate increased, the mean crystal size was reduced and the relative induction time was prolonged. The mean crystal size produced in oxalic acid feeding mode was smaller than that in lanthanum chloride feeding mode, but the trend of the relative induction time with the feeding mode was reverse to that of the mean crystal size. The crystal morphology of lanthanum oxalate, which was produced within the ranges of the reaction conditions in our experiment, was maintained as a needle shape.

The work has been carried out for the development of antifungal antibiotics possessing curative effect in the control of sheath blight disease of rice plant. Soil samples were collected from over 1600 spots throughout the country. More than 1300 specimens which seem to be the genus Streptomyces were isolated from the soil samples. Screening procedures consist of respective processes by four steps. Those are growth inhibition test in liquid culture, paper disk method, dendroid test and green house test. 102 isolates appeared to be active against Pellicularia sasakii when all specimens isolated were examined by the first growth inhibition test. Finally a strain of Streptomyces forming strong antifungal substances against P. sasakii was selected from a soil sample of Mt. Soyo, Kyeongi Province. Antifungal substances formed by the strain were isolated and purified from the culture broth and examined for antimicrobial activities as to be specific against fungi but not active on bacterial growth.

The redox properties of a homogeneously-precipitated $TiO_2$ rutile powder with a BET surface area of ~$200 m^2$/g, consisting of an acicular primary particle, were characterized using photocatalytic reaction in aqueous 4-chlorophenol, Cu-EDTA and Pb-EDTA solutions under ultraviolet irradiation, compared to those of commercial P-25 X$200 m_2$ powder with a spherical primary particle as well as home-made anatase $TiO_2$ powder with ~$200 m^2$/g BET surface area. Here, the anatase powder also includes mainly the primary particles very similar to the acicular shapes of the rutile $TiO_2$ powder. The rutile powder showed the fastest decomposition rate and the largest amount in the photoredor, compared with the anatase or P-25 powder, while the anatase powder unexpectedly showed the slowest rate and the smallest amount in the same experiments regardless of almost the same surface area. From results, the excellent photoredox abilities of this rutile powder appears to be due to specific powder preparation method, like a homogeneous precipitation leading to direct crystallization from the solution, regardless of their crystalline structures even when having the similar particle shape and surface area.
