  • Reverse osmosis technology is being used on large scale for treatment of ground water, brackish water, wastewater and sea water. The most challenging issue in RO process is carbonate scaling which is directly linked with the efficiency and economy. Considering the natural phenomena of carbonate scaling different adaptations have been made to control scaling on the surface of RO membrane including acid dosage and antiscalant addition. As carbonate scaling is directly related with pH level of feed water, present study describes an experimental approach to reduce scaling on RO membrane by lowering the feed water pH by purging $CO_2$. In this comparative study four different conditions including control process (without any scale inhibitor), with dosage of antiscalant, with purging of $CO_2$ and with co addition of antiscalant and $CO_2$ in a feed stream line; it was established that $CO_2$ is a better appliance to reduce carbonate scaling on the membrane surface by reduce pH of feed stream. It was also observed that $CO_2$ and antiscalant mutually function better for scale control.

  • This study was aimed at ultrafiltration (UF) as a pretreatment before reverse osmosis (RO) within the scheme of hybrid reverse osmosis-multistage flush (RO-MSF) desalination. Seawater at elevated temperature (after MSF heat-exchangers) was used as a feed in this process. The pretreatment system was represented as a set of functionally-linked technological segments such as: UF filtration, backwashing, chemical- enhanced backwashing, cleaning, waste disposal, etc. The process represents the sequences of operating cycles. The cycle, in turn, consists of the following unit operations: filtration, backwashing and chemical-enhanced backwashing (CEB). Quantitative assessment was based on the following indicators: normalized permeability, transmembrane pressure, specific energy and water consumption, specific waste generation. UF pre-treatment is accompanied by the following waste streams: $W1=1.19{\times}10$ power of $-2m^3$ (disposed NaOCl with 0.0044% wt.)/$m^3$ (filtrate); $W2=5.95{\times}10$ power of $-3m^3$ (disposed $H_2SO_4$ with 0.052% wt.)/$m^3$(filtrate); $W3=7.26{\times}10$ power of $-2m^3$ (disposed sea water)/$m^3$ (filtrate). Specific energy consumption is $1.11{\times}10$ power of $-1kWh/m^3$ (filtrate). The indicators evaluated over the cycles with conventional (non-chemical) backwashing were compared with the cycles accompanied by CEB. A positive impact of CEB on performance indicators was demonstrated namely: normalized UF resistance remains unchanged within the regime accompanied by CEB, whereas the lack of CEB results in 30% of its growth. Those quantitative indicators can be incorporated into the target function for solving different optimization problems. They can be used in the software for optimisation of operating regimes or in the synthesis of optimal flow- diagram. The cycle characteristics, process parameters and water quality data are attached.

  • In order to understand Changeologically on the meaning of FCST's TMJ (temporo-mandibular joint) treatment procedure, Yi, Shike, Bi, Gen trigrams concerning the jaw and change by treatment were analyzed from the viewpoint of semiotic context of hexagon and holistic interpretation on disease. Yi is meant by jaw but actually indicates mouth made by maxilla and mandible, and it's characters are related with nourishing by aliment and words. But when we eat and speak in the daily life, jaw does not nourish properly it's own body by bad habit or postures. For the treatment of this ill state, there needs punishment and correction symbolized with Shike. Shike has fourth nine meaning obstacles between the two strong lines in the upper and lower end, and so it has the function of mastication and get rid of the fourth nine metaphorically indicating subluxation of axis using CBA and auxiliary measures of four movement or laughing methods. Bi expresses the achievement and effects of consecutive mastication process implicating normalized manifestation of jaw and its linked spinal function. Gen symbolizes removing selfish motive or partiality in advance and reaches the best state of the saint righteously self-nourishable human being.

  • This study evaluated the ecotoxicological properties of livestock waste water treated by a LID (Low Impact Development) system, using a mixture of bio-reeds and bio-ceramics as suitable bed media for a subsequent treatment process of a livestock wastewater treatment plant. The relationship between the pollutant reduction rate and the ecotoxicity was analyzed with the effluents from the inlet pilot plant, with vegetated swale and wetlands and the batch type of an infiltration trench. Each pilot plant consisted of a bio process using bio-reeds and bio-ceramics as bed media, as well as a general process using general reeds and a bed as a control group. The results indicated that, after applying the HRT 24 hour LID method, the ecotoxicity was considerably lowered and the batch type pilot plant was shown to be effective for toxicity reduction. The LID method is expected to be effective for water quality management, considering ecotoxicity by not only as a nonpoint source pollution abatement facility but also, as a subsequent treatment process linked with a livestock manure purification facility. It is necessary to take the LID technic optimization study further to apply it as a subsequent process for livestock wastewater treatment.

  • An integrated sewer management system was developed for the analysis of sewer flow and for optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue in order to construct user-friendly management system. The developed system was applied to a residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of developed system, and the modeling of sewer flow was implemented using RUNOFF, EXTRAN, TRANSPORT in SWMM. This system is now in the process of connection to the management system of watershed and surface environment in order to develope an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer line and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for optimal management, but also for decision support system to examine the efficiency of planning and implementation of sewer projects.

  • Parkinson's disease (PD) is a common neurodegenerative disorder characterized by a progressive loss of dopaminergic neurons in the substantia nigra. While its precise etiology is unknown, such factors as oxidative stress, impairment of mitochondrial respiration, excitotoxicity and inflammation may play roles in its pathogenesis. Although the role of apoptosis in the process of dopaminergic neuronal death has been highlighted in studies using postmortem brains and experimental models of PD, other evidence implicates both apoptosis and non-apoptotic death in PD.

  • Objectives :The Korean Medical concept Gak-Gi(脚氣) is understood as being identical to Beriberi and Vitamin B1 deficiency, without the necessary investigation that is required in such identification. Therefore this study aims to systematically compare these two concepts for thorough investigation. Methods : Research was carried out in two directions. First, the cause, symptoms, treatment principles of Gak-Gi(脚氣) in the medical texts were analyzed. Second, the process of the Beriberi theory development and its identification with Gak-Gi(脚氣), medical information on Beriberi, and the basis of various diseases that have been linked to Gak-Gi(脚氣) were studied. Results of the two directions were used to compare Gak-Gi(脚氣) and Beriberi. Results : Gak-Gi(脚氣) and Beriberi overlap in many aspects. However, unlike Beriberi which is understood as nutrient deficiency essentially, Gak-Gi(脚氣) can be caused by exterior pathogens such as wind toxin, while its different manifestations and treatment principles cannot be fully explained by nutrient deficiency. Conclusions : Gak-Gi(脚氣) could be understood as a type of syndrome in which causes and symptoms are connected, where symptoms start in the legs, moving upwards. It cannot be identified with Beriberi, which has been interpreted as a single disease.

  • The virtual patient dataset is a collection of diagnostic data from various sources acquired from a single patient into a coordinate system of three-dimensional visualization. Virtual patient dataset makes it possible to establish a treatment plan, simulate various treatment procedures, and create a treatment planning delivery device. Clinicians can design and simulate a patient's smile on the virtual patient dataset and select the optimal result from the diagnostic process. The selected treatment plan can be delivered identically to the patient using manufacturing techniques such as 3D printing, milling, and injection molding. The delivery of this treatment plan can be linked to the final prosthesis through mockup confirmation through provisional restoration fabrication and delivery in the patient's mouth. In this way, if the diagnostic data superimposition and processing accuracy during the manufacturing process are guaranteed, 3D digital smile design simulated in 3D visualization can be accurately delivered to the real patient. As a clinical application method of the virtual patient dataset, we suggest a decision-making method that can exclude occlusal adjustment treatment from the treatment plan through the digital occlusal pressure analysis. A comparative analysis of whole-body scans before and after temporomandibular joint treatment was suggested for adolescent idiopathic scoliosis patients with temporomandibular joint disease. Occlusal plane and smile aesthetic analysis based on the virtual patient dataset was presented when treating patients with complete dentures.
