The prototype biofilter was constructed in Suwon campus of Seoul National University and monitored for temperature and treatment efficiencies during a two-year programme. During the winter, daily influent wastewater temperature averages $7.7C^{\circ}$; without heating in 2000 experiment, the treatment efficiencies for BOD and SS droped down to 88.7% and 68.4%, respectively. However, as increased the influent wastewater by installting a heater tank before the biofilter tank in 2001 at the same period ($Feb.\;9{\sim}Mrach\;30$) of 2000 experiment, average daily influent temperature which was $7.2C^{\circ}$ increased to over $18.2C^{\circ}$. As a result, effluent quality remains excellent through the winter and even the post winter with BOD and SS values close to less than 10 mg/L. Nitrification follows temperature patterns. However, there was no improvement of treatment efficiency in total nitrogen (T-N) was observed by increasing temperature.

Anterior crossbite is a common malocclusion in the early deciduous dentition. Even today, many these malocclusion patients are not treated until the mixed or permanent dentition. And the purpose here is to emphasize the need for early diagnosis and possible treatment for these anterior crossbite malocclusions and their associated facial patterns. Case histories of 4 patients selected from the author's practice are presented. Different methods of treatment are evaluated. Some improvement was achieved in all patients from an early interceptive regimen, although ultimately corrective orthodontic treatment may still be needed in some. It is concluded that early interception of deciduous anterior crossbite malocclusion should by attempted in patients ; there should be no delemma in reaching such a decision. And it is essential for diagnosis and treatment to determine exact variations in growth when some appliance are used, it is recommended that growth-related records be made as early as possible.

Autism is a life-long neurodevelopmental disorder characterized by qualitative abnormalities in reciprocal social interactions and patterns of communication. Patients with autism are difficult to manage during dental treatment. Thus they need special consideration like physical restraint, conscious sedation or general anesthesia. A 5-year-old male dental patient with autism was reffered to dental treatment under conscious sedation using intramuscular midazolam that creats anterograde amnesia. Dental procedure using midazolm which cause anterograde amnesia can be effective treatment strategy in autism patient.

In the paper, with corrosion velocity measurement and metallographic observation on specimens after sulfuric acid/ferric sulfate boiling experiment, intergranular corrosion tendency of the new type ultra low carbon stainless steel developed by ourselves which experienced solution treatment at different temperatures was evaluated. A VHX 500 super depth field tridimensional microscope was used to observe corrosion patterns on the sample surfaces. The depth and width of grain boundary corrosion groove were measured by the tridimensional microscope, which indicated that the corrosion degrees of the samples which received solution treatment at different temperatures are quite different. Transgranular corrosion at different degree occurred along with forged glide lines. After comparison it was proved that the stainless steel treated at $1100^{\circ}C$ performs very well against intergranular corrosion.

An experimental investigation with diode laser system was carried out to study the effect of surface heat treatment on the die materials(SM45C, SKD11, SK3). The surface heat treatment characteristics of the laser beam are evaluated using hardness tests, optical microscopy, X-ray diffraction and energy dispersive X-ray spectroscopy(EDS). Results indicated that the beam size, focal length, feed rates are changed surface hardened characteristics. SM45C is higher hardness than other materials and composed to martensite grain at hardened zone, whereas other materials(SKD11, SK3)are low hardness than expected and composed to austenite and allayed martensite at hardened zone. The intensive X-ray diffraction patterns of (110)-(200)-(211) is detected hardened surface and the hardened surface distributed plenty of carbon density than metal zone.

Metaplastic breast cancer (MBC) is a rare type of breast carcinoma, characterized by various combinations of mesenchymal, adenocarcinoma and other epithelial components. MBC often manifests as a large mass, with low axillary lymph node involvement and poor prognosis. Knowledge and treatment patterns about MBC demographics, presentation and tumor characteristics are very limited. In clinical practice, MBC is usually treated based on the guidelines developed for infiltrating ductal carcinoma (IDC). The ideal treatment paradigm for MBC is unknown due to its low incidence and pathological variability, so potential predictors of treatment efficacy need to be explored. This review summarizes the current models and strategies for MBC according to the published literature.

A Circulating Fluidized-Bed (CFB) with an internal nozzle and a partition wall was proposed. The technique of fluidization is related to operations first used commercially in the fields of metallurgical and mechanical engineering such as the heat treatment of metals and power station combustors. In the modified CFB, an internal nozzle and a partition wall were additionally set in the main bed. This cold mode CFB apparatus made of acrylic resin; the main bed is 1,500mm high and 100mm in the inner diameter, the internal nozzle is 130mm high and 10mm in the inner diameter, and the partition wall is 7mm thick and 100mm in the diameter. Glass beads of $89{\mu}m$ in the mean diameter were employed as bed materials.

Purpose : The purpose of this study was to investigate the effect of mat activities in PNF on improvement of balance performance in stroke patients. Methods : Included 12 persons with stroke who were living in the community. They participated in exercise class for 60minutes duration three times a week for 6 weeks. Mat activities in PNF program was modified PNF patterns and techniques on various posture. Balance indexes were measured at pre-treatment, post-treatment and follow-up by K.A.T.3000. Results : Balance index scores had larger improvements after 6 weekends of treatment(p<.05) than pre-treatment, also follow-up test(p<.05). Conclusion : The result of this study showed that PNF mat activities intervention can improve balance performance in disabled persons after stroke.

Microglia are the confined immune cells of the central nervous system (CNS). In response to injury or infection, microglia readily become activated and release proinflammatory mediators that are believed to contribute to microglia-mediated neurodegeneration. In the present study, inflammation was induced in the immortalized murine microglial cell line BV-2 by lipopolysaccharide (LPS) treatment. We firstly performed phosphoproteomics analysis and phosphoinositide lipidomics analysis with LPS activated microglia in order to compare phosphorylation patterns in active and inactive microglia and to detect the pattern of changes in phosphoinositide regulation upon activation of microglia. Mass spectrometry analysis of the phosphoproteome of the LPS treatment group compared to that of the untreated control group revealed a notable increase in the diversity of cellular phosphorylation upon LPS treatment. Additionally, a lipidomics analysis detected significant increases in the amounts of phosphoinositide species in the LPS treatment. This investigation could provide an insight for understanding molecular mechanisms underlying microglia-mediated neurodegenerative diseases.

Objectives The purpose of this study is to figure out the tendency of the commonly-used-pattern-identification and treatment for Hyperhidrosis by reviewing Korean clinical studies. Methods 18 articles which were published from August, 2004 to December, 2018. were obtained from the National discovery for science leader (NDSL), Research information sharing service (RISS), and Oriental medicine advanced searching integrated system (OASIS) by using keyword 'hyperhidrosis'. Results The most commonly-used-pattern-identification were the patterns with 'Heart' and 'Spleen-stomach'. Hyungbangsabaek-san and Taeeumjowi-tang were the most frequently used herbal medicine. The most common acupoints was LI4. The most common method of assessment was VAS. Conclusions This study identifies the most common pattern identification and treatment for hyperhidrosis. Developing systematic standards of pattern identification and treatment can be possible with further studies.
