In this study was the stoker incinerator system with SNCR(Selective Non-Catalytic Reduction). While this system was favored with the view of the possibility of the reducing waste volume and recovery of waste heat, it also has a disadvantage, that is, the need for the second to treat dust, HCl, CO, etc. So far, even though a great deal of research had been done, the study on heat-flow analysis with reduction model and NO reduction with SNCR had not been investigated enough. The temperature distribution in the system and excess amount of oxygen influence the efficiency of NO reduction, resolution in the production, resolution in the production of NO at 1700K and the temperature range of 1200-1250K when the highest NOx reduction efficiency occurred. Hence, this study was focused to flow mixing pattern and NOx reduction efficiency as the flue gas velocity, NH3 injection velocity, particle size and particle density.
Appetite Suppressor Induced Psychosis
Soon-Jai Kwon,양종철,박태원,정영철 대한정신약물학회 2010 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.8 No.3
Amphetamine analogues are widely prescribed for the treatment of obesity; their therapeutic mechanisms are appetite suppression and sympathomimetic effects. However, due to their structural similarities to amphetamine, patients who take appetite suppressants may experience psychotic symptoms such as hallucinations or paranoid mental states. We report on a patient who had been taking the appetite suppressant, phentermine for 2 years and experienced a sudden onset of psychotic symptoms. She had no past history of psychiatric treatment and no familial history of psychiatric illness. She experienced continuous auditory hallucinations and paranoid delusions, without disordered thinking, and significant negative symptoms. She stopped taking medication immediately following the onset of symptoms, which lasted for about 10 days thereafter. This case illustrates that phentermine,the most commonly prescribed appetite suppressant, can cause psychotic symptoms; warnings about these possible side effects should be made explicit to all those considering the use of appetite suppressants.

PERFORMANCE ANALYSIS FOR H.264 VIDEO CODING
Jai-jin Jung,Soon-kak Kwon 한국멀티미디어학회 2007 한국멀티미디어학회 국제학술대회 Vol.2007 No.-
The international video coding standard H.264 / MPEG-4 part 10 aims at having significant improvements in coding efficiency, and error robustness in comparison with the previous standards such as MPEG-2, H.263, MPEG-4 part 2. This paper presents the performance comparison among the video coding algorithms. The performance comparisons show that H.264 can achieve a coding efficiency improvement of about 1.5 times or greater for each test sequence related to multimedia, SDTV and HDTV.

We report a case of AIDS-related Kaposi's sarcoma in a 47-year-old male. He was diagnosed as HIV-positive 3 years ago. He developed two asymptomatic purple-colored papules on the nose and right elbow. The histopathological finding showed abnormally proIiferated and dilated vessels, vascular slits, spindle shaped cells, and extravasated erythrocytes. In immunohistochemical studies, the cryptic vessels was positive with CD34, but negative with factor XIIIa and factor VIII-related antigen, Human herpesvirus-8 was found by PCR. We think that this is the first reported case of AIDS-related Kaposi's sarcoma in Korean dermatologic literature.
Inheritance of Tolerance of Maize Inbreds to Exserohilum turcicum in North Korea

Exserohilum turcicum is considered serious destructive disease of maize (Zea mays L.) in North Korea. This study aimed to understand genetic inheritance and combining ability of newly bred lines of maize tolerant to E. turcicum by diallel crosses. Three diallel sets for two different ecological regions and one agronomic trait; eastern (E), northern (N) and stay green (SG) involving 29 inbred lines were tested in eight locations of 2000 and 2001. E. turcicum infections were under natural conditions, respectively. Lines used were selected for high yield potential in test crosses with good agronomic traits and tolerance to biotic and abiotic stresses. Selection for race specific high resistance to biotic stresses was avoided to select quantitatively inherited genes. Host plant responses to E. turcicum were rated on a scale of 1 (highly tolerant) to 9 (highly susceptible). Highly significant variations were recorded in all trials. General combining ability (GCA) mean square was roughly twice that of specific combining ability (SCA). The genotype (G) by environment (E) interaction was highly significant. The overall results of genetic studies in three diallel sets show that genetic control for inbred tolerance to E. turcicum is polygenic and quantitatively inherited. New inbreds; E-3, N-1 and SG-4 confer better tolerance to E. turcicum than the widely used inbreds; Mo17, and B73. Proper use of genetic information from this study shall increase of corn production under high E. turcicum infection in the Far Eastern Regions of Korea and China.
