A 6-year-old, spayed female Cocker Spaniel was presented with generalized seborrhea sicca. Initially gallbladder mucocele (GM) was suggested by high liver enzyme activities and a stellate pattern in ultrasonography. There were no responses during 16 months of medical treatments for GM. Hormonal assay and histopathological findings were consistent with a diagnosis of hypothyroidism. Levothyroxine therapy led to rapid resolution of dermatologic, serum chemical and ultrasonographic abnormalities. This report describes serial changes of skin lesions, serum chemistry and ultrasonography in a dog with concurrent GM and hypothyroidism following treatment of hypothyroidism.

An 18-year-old, neutered female, Yorkshire terrier was presented with abdominal mass. Large abdominal mass was located in right 4th and 5th mammary glands. Surgically excised mammary mass was submitted for histological evaluation. Microscopically, multifocal to confluent neoplastic foci were existed from superficial dermis to subcutis. Several different growth patterns such as comedo, solid, cribriform, and micropapillary were present in the neoplastic foci. Large neoplastic mammary ducts showed great invasive tendency to adjacent tissues. Many superficial lymphatic plexuses and dermal lymphatics contained numerous neoplastic cell emboli. Because comedo pattern was demonstrated by more than 50% of the neoplastic cell population, we confirmed this case as mammary comedocarcinoma according to recent classification of canine mammary tumors.

Paper sludge ash, blast furnace slag, fine powder quicklime, anhydrous gypsum, and fly ash as the main ingredients were prepared to suit the salty soils of marine soils. The solidification component is a kind of recycled ceramic, and CaO plays an important role in solidification. The neutralization time after solidification was about 2 weeks, and the compressive strength was about 12N/mm2 in the mortar test after one week incubation with standard yarn. This is about 14 times stronger than the solidifying agent used in the metropolitan area. As a result of applying plate load test to saltous marine soils, we obtained the yield load that can pass the large scale even after 5 days. In the uniaxial compressive strength test, shear strength of about 300 kPa was obtained after 5 days. It will be useful for supplementing the soft ground in the area where marine reclamation is much like the Incheon area.

Corrosion of rebars can occur if there are cracks, moisture and availability of oxygen or carbonation proceeds, chloride penetrates and diffuses in concrete. Once rebars in concrete corrodes, subsequently accompanied with scaling, spalling in concrete cover. As a result of them, the RC structure is seriously deteriorated. In this study, theoretical review and experiments for cathodic protection(CP) have been performed to control corrosion of rebars in concrete contained chlorides and pre-crack. For CP the impressed current system was applied, the protection effect was investigated when rebars was directly contacted with salt water due to crack and open to much chlorides in concrete. In order to investigate the effect of protection, when CP was energized for 1 year, half-cell potential, potential-decay with current density, corrosion ratio, etc. were measured. With the cathodic protection by impressed current system, the depolarized values of all specimen were met NACE Standard, the effect of 34~84% of the ratio of corrosion area and 84~86% of cross-section reduction were calculated.

Preparation of ferrocyanide-anion exchange resin and adsorption test of the prepared resin on the Cs$^{+}$$ion were performed. Adsorption capability of the prepared resin on the Cs$^{+}$ion in the simulated citric acid based soil decontamination waste solution was 4 times greater than that of the commercial cation exchange resin. Adsorption equilibrium of the prepared resin on the Cs$^{+}$ion reached within 360 minutes. Adsorption capability on the Cs$^{+}$ion became to decrease above the necessary Co$^{2+}$ion concentration in the experimental range. Recycling test of the spent ion exchange resin by the successive application of hydrogen peroxide and hydrazine was also performed. It was found that desorption of Cs$^{+}$ion from the resin occurred to satisfy the electroneutrality condition without any degradation of the resin.

Procrastination is an irrational choice to delay high-priority work in order to avoid its unpleasantness, despite the fact that the negativity will not cease if the work still remains undone. We hypothesized that (1) people underestimate the future negativity (i.e., delay neutralization) and (2) in order to complete work in a timely manner, one should project oneself into the future so as to recognize that the negativity associated with an activity does not diminish over time. Especially, negative future thinking that is unrelated to the consequence was hypothesized to reduce delay neutralization of negativity. In the present study, undergraduate students made a series of choices between delayed-but-longer and immediate-but-shorter assignment by employing an inter-temporal choice paradigm. We tracked how positive and negative episodic future thinking influenced the degree to which negativity is neutralized over time (Experiment 1). Following this, we confined the experimental condition to negative thinking about the future (Experiment 2). Participants neutralized negativity involved in assignment as a function of time, suggesting that procrastination arises from the delay neutralization of the negativity. Critically, such neutralization was significantly reduced when participants imagined a negative future event, but this did not occur when they imagined a positive future event (Experiment 1), or when participants did not think about the future (Experiment 1, 2). Our findings suggest that, prior to making a decision between work and indulgence, imagining negative future events can be an effective way to reduce the neutralization of delayed negativity and, in turn, procrastination.

A 12-year-old intact male, Alaskan Malamute dog, which lives in the countryside, was presented with inflammation and pain around perineal areas. Thorough examination revealed maggots and punched-out round holes lesion around the perineal region. Complete blood counts (CBC) and serum biochemical examinations showed no remarkable findings except mild anemia and mild thrombocytosis. The diagnosis was easily done, based on clinical signs and maggots identification. Cleaning with chlorhexidine, povidone-iodine lavage and hair clipping away from the lesions were performed soon after presentation. SNAP 4Dx Test (IDEXX Laboratories, Westbrook, ME, USA) was performed to rule out other vector-borne diseases since the ticks were found on the clipped area and vector-borne pathogens. The test result was negative. The dog in this case was treated with ivermectin (300 mcg/kg SC) one time. Also, treatments with amoxicillin clavulanate (20 mg/kg PO, BID) was established to prevent secondary bacterial infections. Then, myiasis resolved with 2 weeks and the affected area was healed.

A 12-year-old spayed female, Golden Retriever presented with dyspnea and lethargy of 3 months duration. Pericardial effusion and cardiac mass were identified on echocardiography. Pericardiectomy and mass resection were performed for treatment of pericardial effusion and histopathological analysis was conducted for the definitive diagnosis. The mass was diagnosed as hematoma with mainly erythrocyte, fibrin and many of neutrophils based on microscopic description. Severe purulent pericarditis thickened by inflammatory cells and reactive fibrous tissue were identified, but not diagnosed as neoplasm. This is the first case report in veterinary literature of a dog with pericardial effusion caused by cardiac hematoma.
