MPEG-I is actively working on standardization on the coding of immersive video which provides up to 6 degree of freedom (6DoF) in terms of viewpoint. 3DoF+ video, which provides motion parallax to omnidirectional view of 360 video, renders a view at any desired viewpoint using multiple view videos acquisitioned in a limited 3D space covered with upper body motion at a fixed position. The MPEG-I visual group is developing a test model called TMIV (Test Model for Immersive Video) in the process of development of the standard for 3DoF+ video coding. In the TMIV, the redundancy between a set of input view videos is removed, and several atlases are generated by packing patches including the remaining texture and depth regions into frames as compact as possible, and coded. This paper presents an atlas generation method that removes small-sized blocks in the atlas for more efficient 3DoF+ video coding. The proposed method shows a performance improvement of BD-rate bit savings of 0.7% and 1.4%, respectively, in natural and graphic sequences compared to TMIV.

At the Seoul first slaughter house, 2,964 heads of swine were examined for the infection and distribution of Cysticercus tenuicollis. The results were summarized as follows. 1. The Cysticercus tenuicollis were detected from 106 heads of swine and the infection rate were 3.58 percent. 2. Incidence at each province were 5.7% in Jeon-ra-puk Do, 4.4% in Chung-cheong-nam Do, 3.83% in Kyong-sang-nam Do, 3.57% in Jeon-ra-nam Do, 2.52% in Kang-won Do, 1.75% in Kyong-sang-puk Do, and Kyong-gi Do and Seoul City were not recognized. 3. The monthly variation of the infection of Cysticercus tenuicollis were not found nearly through a year. 4. The usual habitat of Cysticercus tenuicollis were recognized the omentum and liver, but unusually one case was found around the rectum.

This paper give further assessment on the original DoP-CPD classification scheme. This paper provides some additional comparative study on the DoP-CPD with H/A/alpha classifier in terms of multi look effects and classification performances. The statistics and multi looking effects of the DoP and CPD were analyzed with measured polarimetric SAR data. DoP-CPD is less sensitive to the number of averaging pixels than the entropy-alpha technique. A DoP-CPD diagram with appropriate boundaries between six different classes was then developed based on the data analysis. A polarimetric SAR image DoP-CPD classification technique is verified with C-band polarimetric RADARSAT-2 images.

Hyperadrenocorticism (HAC) is a common endocrinopathy among dogs that causes multisystemic signs. This study was conducted to evaluate cardiocirculatory, biochemical, and hemostatic parameters in dogs with HAC at diagnosis, in addition to verifying whether abnormal parameters could be controlled by initial treatment with trilostane. Fifteen dogs with HAC were assessed by systolic blood pressure measurement, electrocardiography, Doppler echocardiography, serum concentration of troponin I, and biochemical and hemostatic profile at diagnosis and after trilostane therapy. Unlike biochemical parameters, hemostatic and cardiocirculatory parameters were not significantly influenced by the onset of treatment. The authors believe that clinical treatment with trilostane for 3 to 4 months might not be sufficient for the stabilization of cardiocirculatory abnormalities such as hypertension. Therefore, dogs with HAC must receive cardiocirculatory monitoring at diagnosis and during drug treatment.

Although a variety of preparation methods for DoS attacks and DDoS attacks are presented, it is still being exploited, the vulnerability with networks and protocols. In particular, When was built environment that can be used anywhere in the Internet, Internet of Things is entering era. Thus, the conventional computer, as well as household appliances, etc. DoS attack targets or are likely to do the attacker role is increasing. In this paper, we first find out about the type and characteristics of DoS attacks. Open source operating system, Linux has iptables that packet filtering tool and firewall programs. Using iptables to set the policy ruleset against DoS attacks.

The simple imcroprocessor device was provided for the control of dissolved oxygen(DO) level. The DO analog signal output from fementer was used as a measurement variable and the agitation speed of fermenter was used as a manipulatio variable. Agitation speed was manipulated to maintain DO level above 10% of saturation condition during cell growth period with microprocessor. Since the experimental resultsshowed that the DO level was maintained above 10% and agitation speed was inverse proportional to DO level ithis simple control device can be used for the DO control of fermenter.

To investigate the effects of the dissolved oxygen concentration (DO) on Scope for growth (SFG) of the manila clam, Ruditapes philippinarum, we measured $LC_{50}$, filtration, respiration, ammonia excretion, and assimilation rates under $23\pm0.5^{\circ}C$ as a function of DO. The $LC_{50}$ of DO for R. philippinarum, was 2.4 mgDO $L^{-1}$. With decreasing DO, filtration and respiration rates of R. philippinarum decreased, while ammonia excretion rate increased, The assimilation rate was $68.2\%$ at 6.5 mgDO $L^{-1}$, decreased to $29.8\~39.3\%$ at 3.5 mgDO $L^{-1}$. R. philippinarum had positive SFG's at the $DO{\geq}2.5mgDO\;L^{-1}$.

Pleurotus eryngii has recently become a major cultivated mushroom; it uses tetrapolar heterothallism as a part of its reproductive process. Sexual development progresses only when the A and B mating types are compatible. Such mating incompatibility occasionally limits the efficiency of breeding programs in which crossing within loci-shared strains or backcrossing strategies are employed. Therefore, understanding the mating system in edible mushroom fungi will help provide a short cut in the development of new strains. We isolated and identified pheromone and receptor genes in the B3 locus of P. eryngii and performed a functional analysis of the genes in the mating process by transformation. A genomic DNA library was constructed to map the entire mating-type locus. The B3 locus was found to contain four pheromone precursor genes and four receptor genes. Remarkably, receptor PESTE3.3.1 has just 34 amino acid residues in its C-terminal cytoplasmic region; therefore, it seems likely to be a receptor-like gene. Real-time quantitative RT-PCR (real-time qRT-PCR) revealed that most pheromone and receptor genes showed significantly higher expression in monokaryotic cells than dikaryotic cells. The pheromone genes PEphb3.1 and PEphb3.3 and the receptor gene PESTE3.3.1 were transformed into P5 (A3B4). The transformants were mated with a tester strain (A4B4), and the progeny showed clamp connections and a normal fruiting body, which indicates the proposed role of these genes in mating and fruiting processes. This result also confirms that PESTE3.3.1 is a receptor gene. In this study, we identified pheromone and receptor genes in the B3 locus of P. eryngii and found that some of those genes appear to play a role in the mating and fruiting processes. These results might help elucidate the mechanism of fruiting differentiation and improve breeding efficiency.

A rapid, sensitive and selective liquid chromatography-tandem mass spectrometric (LC/MS/MS) method for the determination of eupatilin in human plasma was developed. Eupatilin and internal standard, (S)-[N-3-(4-(2-(1-methyl-5-tetrazolyl)-pyridine-5-y1)- 3-fluorophenyl)-2-oxo-5-oxazolidinyl]methyl acetamide (DA-7867) were extracted from human plasma by liquid-liquid extraction and analyzed on a phenyl-hexyl column with the mobile phase of acetonitrile-ammonium formate (10 mM, pH 3.0) (60:40, v/v).
