<P><B>Objectives</B></P><P>Poststroke emotional incontinence (PSEI) has been associated with serotonergic dysfunction. Polymorphisms of serotonin transporter (5‐HTT) and serotonin 2a receptor (5‐HTR2a) genes may regulate serotonergic signaling at brain synapses, and this study was to investigate associations with PSEI in an East Asian population.</P><P><B>Methods</B></P><P>In 276 stroke cases, PSEI was diagnosed by Kim's criteria. Covariates included age, gender, education, history of depression or stroke, current depression, and stroke severity and location. Genotypes were ascertained for 5‐HTT gene‐linked promoter region (5‐HTTLPR), serotonin transporter intron 2 variable number tandem repeat, 5‐HTR2a 1438A/G, and 5‐HTR2a 102 T/C. Associations with PSEI were estimated by using logistic regression models, and gene–gene interactions were investigated by using the generalized multifactor dimensionality reduction method.</P><P><B>Results</B></P><P>PSEI was present in 37 (13.4%) patients. The 5‐HTT gene‐linked promoter region <I>s</I>/<I>s</I> genotype was independently associated with PSEI.

Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.

The total hydrocarbon distribution of oil products obtained from the pyrolysis of four kinds of mixtures of polyethylene-polystyrene waste has been studied by multidimensional chromatography(high performance liquid chromatography followed by capillary gas chromatography)/mass spectrometry. Saturated, unsaturated and aromatic hydrocarbons in oil products were selectively pre-separated according to structural groups by HPLC and the weight fraction of each group was estimated by analysis of each component using GC-FID response factors. The hydrocarbon distribution of aliphatic fraction consists of C_5 to C_25 saturated and unsaturated hydrocarbons. And that of aromatics fraction consists of benzene, toluene, xylene, styrene, propenyl benzene, naphthalene, and some of derivatives. Pyrolysis temperature did not affect the ratio of total weight fraction of aliphatic over aromatic hydrocarbon distribution in case of PS only and PE-PS mixtures (1:1 and 1:4 wt. ratio) as a feed while affected the ratio of total wt. fraction in case of PE only. The optimal temperature for the maximum oil production was 600℃ for pyrolysis of PS and 1:1 and 1:4 mixtures of PE and PS. The optimal condition for aromatic recovery was 600℃ with 1:1 mixture of PE and PS. In this condition, aromatic was produced up to 90% of total oil product. The maximum yield of toluene, xylene, styrene, and propenyl benzene were 8.6, 8.9, 51.0 and 7.4% of feed for pyrolysis PS at 700℃, respectively. However, only 1.3% naphthalene was recovered at 700℃ with 1:1 PE:PS(by wt.).

Recently, a quantity of medical waste has been increased according to the expansion of medical facilities caused by rising in living standard and in need for a healthy life. The status of medical waste management is, however, still in an infant stage, Incineration has been proven to be an effective technology of reducing volume, mass and toxicity of medical waste. There are few medical waste incinerators in Korea, but most are not even operated properly. And pathogen's release and emission of various air pollutants can affect the public directly because most medical waste incinerators are located in the crowded area. To assess the release potential of pathogenic bacteria from biomedical waste incinerator, the incinerator is spiked with 3.70 x 10의9승 spores of Bacillus stearothermophilus that are poured on crumpled newspaper in plastic bags and are burned with routine waste. The experimental result of air emission, the total destruction efficiency of surrogate bacteria was99.9957%. SO₂ and NOx emission are lower than emission standards. But higher value of CO emission are made with three times.

Medical waste has been regulated legally by "Isolated and related medical waste treatment rule" enacted in 1981. Recently, quantity of the medical waste has been increased according to the expansion of medical facilities caused by rise in living standard and usage of non-recyclable medical instruments. The management of medical waste still is not well established because of insufficient recognition in hospital, small scale of medical waste treatment industry and deficiency of treatment facilities, In this study, an improvement strategy of medical waste management system in Seoul city was established by considering present collection system and introducing the possibility of exclusive medical waste incinerator. For doing this, EPA's WRAP program was used to obtain an optimum solution that can minimize cost of the collection and the treatment of medical wastes. Therefore new collection system was proposed to minimize collection distance, costs and the risk of secondary infection. This study also proposed an optimal site and needed capacity for exclusive medical waste incinerator and the market opportunity of exclusive medical waste incineration enterprise.

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).

Grid computing is an emerging technology that promise to unify resources and computing power in many organizations together. It couples a wide variety of geographically distributed computational resources, and presents them as a unified integrated high-end computer. The Globus Resource Allocation and Management(GRAM) service provides for the management and remote execution of jobs defined using a standard Resource Specification Language(RSL) requested by client in grid environment. However, Currently the GRAM has very limited functionality to support for applications that required special execution environment. Here, we provide a proposal for Execution Environment Information interacted with broker to support the GRAM's special execution environment.
