A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

In this paper, a theoretical analysis of zero-voltage-switching inverter with each capacitor in parallel with each switching device is presented along with experimental results. The proposed inverter offers both zero turn-on and zero turn-off switching losses, yielding high efficiency at high frequencies. In addition, the soft switching method reduces switching noise associated with the high frequency ringing and high voltage stress at the switching instants. Also, the equivalent circuit of a matching transformer converted primary to secondary side and normalized parameter for generally description are introduced to the estimation of the proposed circuit. A 1KW class-D inverter was built and tested. The theoretical results are in good agreement with the experimental ones. ZVS can be achieved above the resonant frequency and in a limited range of the load resistance. The proposed circuit is considered to be useful for induction heating applications.

This plan of rural housing-development is to present a new orientation for the residential culture that can meet the shifting demands of modern people as their attitudes toward naturalistic life. In this plan, sites of possible, a new housing complex is designed to supplement the site partition problem of existing housing complex by using attractiveness that the site has as a residence environment in housing planning. The conclusion can be summarized as follows. 1. Currently, most residential developments on slopes are planned with excessive slope cutting or filling on existing natural slopes rather than utilizing existing contours. In consideration of this, this proposed plan uses the existing contours of the slope to the maximum capacity in site planning. 2. The majority of the home site buyers are between the ages 30's to 50's of middle to high level incomes. Reflecting the financial needs of these families, home construction was planned by using building methods that require lower costs. 3. Reflected open-space furtherance maximum at design of community equipment for party's offer to sale in lots persons, from site purchase recognition of construction to in package sale in lots way select. 4. Considered to preserve existing natural-food life in way financial world stroke maximum, and accomplish creation with existing vegetation. Also, did planting considering privacy, and considered vegetation's environment adaptation degree because using midland style vegetation. 5. Garden wished to offer an opportunity that can make by oneself directly depending on each fondness and character to tenants. If is this intuition, wished to design, and maintained spur of housing development because housing development uses maximum natural history style comparing with other power jars all. Also, because considering people who move in housing-development, designed, and tried to make housing-development that want to live most offering the convenience.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Process characterization of waste plastics pyrolysis in a bench scale fluidized bed test unit was investigated. Feasibility of commercial scale process such as proper feeding system and reaction control ability were analysed and confirmed based on the reaction characteristics varying with the plaxtics and system assemblies. Eight pure or waste plastic samples were collected from the industrial waste plastics generation source in Korea. Selected samples were HDPE, LDPE autobovile interior, XLPE electric wire coat, synthetic rubber, EVA shoe sole, PS(monomer and styrofoam) and ABS. The pattern of decomposition reflected composition and molecular structure of plastics. Decomposition of polyolifin produced linear paraffinic and olefinic compounds. Recovery of styrene monomer and aromatic compounds were attained from the phrolysis of PS and ABS. However, secondary reaction was monitored was monitored even from the pyrolysis of aliphatic samples of XLPE and EVA.
