The objective of this study was to clarify how distance from place of residence to the nearest specialist cancer hospital affects the survival of lung cancer patients and the treatment received. For all patients diagnosed with lung cancer in the Aomori cancer registry database for the period from 2009 to 2011 (n=3,986). The distance to the treating hospital was measured as the straight line from a person's place of residence, and compared with findings from the Ederer II method for calculating relative survival. Information on treatments given was obtained by data extraction. We defined a hospital having respiratory medicine as specialist, while all private hospitals and clinics were included in the general category. Patients attending specialist hospitals numbered 2,548 (67.0%), and those treated at general institutions were 1,255 (33.0%). The patients who had the lowest relative survival with localized lesions lived <20 km from general hospitals and clinics. With more advanced stages, relative survival of those living <20 km from a specialist hospital was the lowest. Although the survival rate was not affected by the distance between place of residence and hospital, even when patients are diagnosed at a localized stage at a general hospital or clinic within 20 km from their home, they did survive longer in comparison with patients diagnosed at a specialist hospital.

The use of biogas is an industrially necessary means to achieve resource circulation. However, since biogas obtained from waste frequently causes corrosion in pipes, it is important to elucidate corrosion mechanisms of the pipes used for biogas transportation. Recently, corrosion failure occurred in a pipe which supplied for the biogas at the speed of 12.5 m/s. Pinholes and pits were found in a straight line along the seamline of the pipe. By using corrosion-damaged samples, residual thickness, microstructure, and composition of oxide film and inclusion were examined to analyze the cause of the failure. It was revealed that the thickness reduction of biogas pipe was ~0.11 mm per year. A thin sulfuric acid film was formed on the surface of the interior of a pipe due to moisture and hydrogen sulfide contained in a biogas. Near the seamline, microstructure was heterogeneous and manganese sulfide (MnS) was found. Pits were generated by micro-galvanic corrosion between the manganese sulfide and the matrix in the interior of the pipe along the seamline. In addition, microcracks formed along the grain boundaries beneath the pits revealed that hydrogen-induced cracking (HIC) also contributed to accelerating the pitting corrosion.
This experiment was conducted to investigate the effect of the cysteine and glutathione on the motility index and morphology of human spermatozoa at the sperm processing in vitro. After treating the sperm with medium containing cysteine and glutathione, we measured the motility index and morphology at 0.5 h and 24 h. 1. Following the sperm culture for 0.5 h after treating the sperm with the medium containing 0, 1, 5, 10 mM cysteine, curvilinear velocity (VCL) was significantly (p<0.05) higher in control than that in all treatments. And straight-line velocity (VSL) was high at 1 mM and average path velocity (VAP) was low at 5 mM and 10 mM. But the motility (MOT) and morphology (NOM) were not different between control and all treatments. Following the sperm culture for 24 h, the MOT was significantly high in treatment groups (58.9, 74.4 and 62.3%), compared with that in control(28.7%) and the VCL was also high in treatment groups (31.4, 37.9, and 34.0 ${\mu}{\textrm}{m}$/s), compared with that in control (21.3 ${\mu}{\textrm}{m}$/s). The VSL (18.4, 21.7, and 18.9 ${\mu}{\textrm}{m}$/s) was significantly higher than control (10.7 ${\mu}{\textrm}{m}$/s) and the VAP (20.3, 24.7, and 21.4 ${\mu}{\textrm}{m}$/s) in treatments was also compared with that in control (12.6 ${\mu}{\textrm}{m}$/s). The NOM was not difference between control and treatments. 2 Following the sperm culture for 0.5 after treating the sperm with the medium containing 0, 1, 5, 10 mM glutathione, the MOT, VCL, VSL, VAP, and NOM were not different between control and treatments. Following the sperm culture for 24 h, the MOT was higher in treatment groups (82.9, 83.6, 83.4%) than in control (51.1%) and the VCL was higher in treatment groups (50.9, 51.3, and 49.4 ${\mu}{\textrm}{m}$/s) than control (34.1 ${\mu}{\textrm}{m}$/s). The VSL was also higher in treatment (17.1 ${\mu}{\textrm}{m}$/s) and the VAP was also higher in treatment groups (30.1, 32.5, and 29.7 ${\mu}{\textrm}{m}$/s) than in control (19.8 ${\mu}{\textrm}{m}$/s). The NOM was not different between control and treatments.
The objective of this study was to see if fairly simple magnetic nano-particle treatment enhances boar semen qualities. Boar semen samples were prepared from the swine AI center and samples were divided by 4 different motility groups (1, >90%; 2. 80~90%; 3. 70~80%; 4. <70%) using computer assisted sperm analysis (CASA) evaluation. Boar semen was extended using BTS extender and same number of magnetic nano-particles as total number of spermatozoa in each sample was treated for 20 min and collected for 5 min at room temperature. Sperm qualities such as motility and viability were evaluated by the CASA before and after treatment. Sperm abnormality and degree of agglutination were also evaluated under the microscopic examination before and after treatment. There were significant changes (p<0.05) on sperm motility from all 4 different groups in the average of 7.11% after treatment. The enhancement of sperm motility changes was more clear in the groups of lower sperm motile groups (<70% and 70~80%; 19.12±1.08% and 5.67±0.71%, p<0.05). The sperm motility character in terms of curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP) and linearity (LIN, %) showed also similar pattern but motility enhancement wear more clear in below 70% motile group. Average sperm viability was increased to 4% by magnetic nano-particles (p<0.05). The percentage of sperm abnormality was also reduced significantly (p<0.05) to the range of 3.7~4.5% before after treatment. The degree of sperm agglutination was also reduced in lower motility groups by the magnetic nano-particle purification.

Recently, as demand of video processor unit rapidly increases, excellent quality of the video has been required. However, generally, video data occurs the quick flame of video due to various external causes in process of acquisition, treatment, and transmission, and major cause of the quick flame of the video is known as the noise. There are various kinds of noise, which are added to the video, AWGN is a typical one. Thus, this thesis suggested algorithm that treats in three methods by scale of the edge through using edge information of local masks. In case that edge pixel is big, it applied spatial weighting according to equation of straight line about direction of edge pixel. In case that edge pixel is middle, it suggested algorithm with spatial weighting filter and average filter, and for the smooth territory, it suggested algorithm that treats with average filter.

In this study, we carried out the each lines of section, using GC (green silicon carbide) whetstone, the SCM415 material which separated by after and before heat treatments process, in 3+2 axis machining centers for integrated grinding after cutting end mill works, the spindle speed 8000 rpm and feed rate 150 mm/min. For the analysis of the centerline average roughness (Ra), we measured by 10 steps stages. Using Finite element analysis, we found the result of the load analysis effect of the assembly parts, when applied the 11 kg's load on both side of the ATC (Automatic tool change) arm. The result is as follows. For the centerline average roughness (Ra) in the non-heat treatment work pieces, are appeared the most favorable in the tenth section are $0.510{\mu}m$, that were shown in the near the straight line section which is the smallest deformation of curve. In addition, the bad surface roughness appears on the path is to long by changing angle, the more inclined depth of cut, because the chip discharging is not smoothly.
Cryopreservation protocols induce partially irreversible damage to mammalian sperm plasma membranes. Previous studies have indicated that adding cholesterol to the plasma membrane, as cholesterol-loaded-cyclodextrins, improves cryosurvival of sperm. Therefore, the purpose of this study was to determine if treating sperm of Markhoz bucks with cholesterol-loaded-cyclodextrins (CLC) (0, 0.75, 1.5, 2.25 and 3 mg/ml diluted $240{\times}10^6$ sperm/ml) in Tris-citric acid-glucose diluents with and without egg yolk (containing 5% glycerol) would improve the post-thaw sperm quality. The motion characteristics were evaluated with a Computer Assisted System Analyzer (CASA); acrosome integrity and vitality were measured with the triple-stain technique. Samples were recovered before and after freezing by means of putting straws into $37^{\circ}C$ water for 30 sec and then parameters were assessed. The results showed that the treatments significantly affected motility, progressive motility, recovery rate, curvilinear velocity, beat cross frequency, live sperm with reacted acrosome, live sperm with unreacted acrosome, dead sperm with reacted acrosorne, and dead sperm with unreacted acrosome during freezing (p<0.05). However; no significant differences were found for average path velocity, straight line velocity, amplitude of lateral head displacement, straightness and linearity (p>0.05). The best results were observed for extender containing 2.25 mg/ml ($240{\times}10^6$ sperm/ml) CLC supplemented with 2.6% egg yolk. In conclusion, the findings of this study indicate improved Markhoz sperm viability and motility following treatment in the presence of egg yolk.

A 6-month-old thoroughbred filly foal had torticollis and circled towards the right side. A local veterinarian treated her twice using dexamethasone for 1 week but there was little clinical improvement. Needles were inserted into Ting points of both hind limb and one ocular acupoint (shang jiao area from GB01). Injection acupuncture (dexamethasone, twice/week) was used at GV16, GB20, BL10 and LU07, for the neck and head. Acupoint GB34 was added to those points at session 4. In addition, a trigger point in the left neck was injected with 0.2 ml ($200{\mu}g$ of apitoxin) of bee-venom diluted with 1 ml of 2% lidocaine from session 1 to session 3. At session 2, the symptoms had ameliorated a little. At session 3, they were much improved; the right ear was completely normal and the neck could be moved about 60% of normal range. At session 4, nodding was possible and stiffness of the neck was much improved, having returned to about 80% of normal range. Three days after session 4, the symptom of torticollis had disappeared completely and the foal could walk in a straight line. In conclusion, the present patient was a case with equine torticollis which showed favourable therapeutic response by combination of needle-acupuncture plus injection-acupuncture with dexamethasone and apitoxin.
Eutectic high chromium cast irons containing 17%Cr and 26%Cr were produced for this research by making each of them solidify unidirectionally. Abrasion wear test against SiC or $Al_2$O$_3$bonded paper was carried out using test pieces cut cross-sectionally at several distances from the chill face of castings. The wear resistance was evaluated in connection with the parameters such as eutectic colony size($E_w$), area fraction of boundary region of the colony($S_B$) where comparatively large massive chromium carbides are crystallized and, average diameter of chromium carbides in the boundary region($D_c$). The wear rate($R_w$), which is a gradient of straight line of wear loss versus testing time, was influenced by the type and the particle size of the abrasives. The $R_w$ value against SiC was found to be larger than that against A1$_2$O$_3$under the similar abrasive particle size. In the case of SiC, the $R_w$ value increased with an increase in the particle size. The $R_w$ value also increased as the eutectic colony size decreased, and that of the 17%Cr iron was larger than that of the 26%Cr iron at the same $E_w$ value. Both of the $S_B$ and $D_c$ values were closely related to the $R_w$ value regardless of chromium content of the specimens. The $R_w$ values of the annealed specimens were greater than those of the as-cast specimens because of softened matrix structures. As for the relationship between wear rate and macro-hardness of the specimens, the hardness resulting in the minimum wear rate was found to be at 550 HV30.
