近年,韓国経済は,中国経済の成長鈍化に伴う世界的な不況が懸念されている中で,その経済成長率の下落が危惧されている。いわゆる「チャイナ・ショック」による世界的な不況の兆しが,韓国経済のあらゆる部門において露呈し,その影響は拡大しつつある。第2次大戦後の日本経済の高度経済成長を追いかけるように,「ハンガン(漢江)の奇跡」ともいわれた高度経済成長を成し遂げてきた韓国経済の成長は,近年,その成長の勢いを失いつつあるのではないかという状況が続いている。本稿では,近年における韓国経済の成長率鈍化とそのパターンの変化に注目して,戦後から最近に至るための成長を振り返ることによって,成長パターンの変化がいつからであったのか,そして,その変化の背景にはどのような要因があるのかについて,主としてマクロ的な視点,つまり国民所得統計データから探ってみることを目的とする。

In this study, Ni-doped MoS<inf>2</inf>was grown by chemical vapor transportation. Photoconductivity results reveal that Ni-doped MoS<inf>2</inf>has an obvious doping level of 1.2 eV and an electrical conductivity of σ ≅ 9.92 × 10<sup>−7</sup>S cm<sup>−1</sup>at room temperature, which is lower than that of undoped MoS<inf>2</inf>(σ ≅ 7.913 × 10<sup>−5</sup>S cm<sup>−1</sup>) owing to the impurity state caused by Ni atoms. Hall effect measurement results indicate that Ni-doped MoS<inf>2</inf>sample is of the n-type and has a higher resistance and a lower mobility than undoped MoS<inf>2</inf>. We further fabricated undoped and Ni-doped MoS<inf>2</inf>photodetectors to understand the operation characteristics of MoS<inf>2</inf>-based photodetectors. Persistent photoconductivity shows that both rise and fall times decreased from 0.33/0.68 to 0.14/0.43 s as Ni atoms were doped in MoS<inf>2</inf>PDs. This work shows that Ni atoms could cause small lattice imperfections to form trap states leading to high resistance, low mobility, small activation energy and short decay time. Therefore, doping Ni atoms in MoS<inf>2</inf>is beneficial for the application of photodetectors.

The present study aimed to investigate the technical feasibility of percutaneous endoscopic mini-hemilaminectomy via a uniportal approach, and to evaluate the possibility of decompression and endoscopic examination of the thoracic and lumbar spinal canals in small dogs during such procedures. Fresh canine cadavers of mixed-breed dogs (n=7) were used in this study. Following injection of a barium and agarose mixture (BA-gel) to stimulate intervertebral disc herniation, percutaneous endoscopic mini-hemilaminectomy was performed using a lateral approach to the thoracic and lumbar vertebrae. BA-gel was removed to decompress the spinal cord using an elevator and rongeurs after mini-hemilaminectomy. Pre and post-operative computed tomography (CT) scans were obtained to evaluate surgical outcomes. Intra-operative complications, incision length, and procedure time were recorded. All procedures were completed with clear visualization of the spinal cord and floor of the spinal canal. The mean total operating time was 58.00 ± 18.06 min. Lengths of incision were under 1 cm in all dogs. Intra-operative complications included iatrogenic nerve root injuries caused by the micro-rongeur in two dogs. CT imaging revealed that removal of BA-gel resulted in sufficient spinal cord decompression. Our findings indicated that percutaneous endoscopic thoracolumbar mini-hemilaminectomy is feasible for spinal cord decompression and allows for adequate observation of the spinal canal. Thus, this technique may be an alternative surgical option for treatment of thoracolumbar disk disease in dogs.

The purpose of this study is to investigate how contemporary college students perceive destroying living things. In Study 1, an attempt was made to make a scale incorporating factor analysis of various items concerning destroying lives. The result extracted three subscales: "brutal destruction for play", "destruction for human living", and "destruction for educational practice". In Study 2, we examined relationships between the three subscales and student past experiences. Results showed that the three subscales had correlations with "wild play experience" and "experience of gathering food". In Study 3, the scale of destroying lives was completed, and the correlation with human living experience and their sense of life value were investigated. The results showed that experience of keeping a pet worked negative toward "brutal destruction" and "dissection". Also, "field play experiences" and "experiences in home" worked positive toward "dissection".

Systematic representation of alkaloid biosynthetic pathways based on ring skeletons has been proposed because the skeleton nucleus of an alkaloid is the main criterion for determination in biosynthetic pathways. So the idea of ring skeletons was extended to apply classification of alkaloid compounds based on ring skeletons and to systematize alkaloid compounds and to examine the performance of this approach to predict biosynthetic pathways based on module elements. We constructed a 2-dimensional binary matrix corresponding to 2546 SRS and 478 pathway-known alkaloid compounds. Here, if ith substring skeleton is present in a target compound, the ith element was set to 1; otherwise, the ith element was set to 0. Relationship of alkaloid compounds with biosynthetic pathways are examined based on the dendrogram produced by Ward clustering method to the matrix. Of 12,243 alkaloid compounds accumulated in KNApSAcK Core DB (http://kanaya.naist.jp/knapsack_jsp/top.html), 3,124 compounds (25.5 %) correspond to the pathway-known ring skeletons (187 ring skeletons), but the remaining 9,119 (74.5%) compounds do not. By examining the sub-ring skeleton similarity of the remaining compounds, it might be possible to obtain clues of pathway information and systemization of all alkaloid compounds. Therefore, the present work focuses on comprehensive systematization of the alkaloid compounds and construction principles of ring skeletons in alkaloids based on subring skeleton profiling.

Platelet-rich plasma (PRP) has an important role in musculoskeletal surgery; however, it has been underutilized for accelerating the healing of abdominal wall defects in veterinary practice. Therefore, the aim of this study was to evaluate the use of commercial polyester/cotton fabric (Damour) as a new composite mesh for the repair of experimentally induced abdominal wall defects in canine models, and to investigate the possible role of PRP for improving such repair and reducing allied complications. For this purpose, abdominal wall defects were created in 24 healthy mongrel dogs and then repaired with mesh alone (control group) or mesh and allogenic PRP (PRP group). Dogs were euthanized after 2 or 4 months for gross examination of implantation site, detection of adhesion score and hernia recurrence. Moreover, tissue samples were collected for histological and gene expression analyses for neovascularization, collagen formation and tissue incorporation. Hernia recurrence was not recorded in PRP-treated dogs that also displayed significantly more neovascularization and less severe adhesion to the underlings (1.08 ± 0.51) in comparison to control group (2.08 ± 0.99). Histological and molecular evaluation confirmed the gross findings that collagen deposition, new vessel formation, and overexpression of angiogenic and myofibroplastic genes (COL1α1, COL3α1, VEGF and TGFβ1) were observed more frequently in the PRP group, at both time points. In conclusion, we found that addition of allogenic PRP to Damour mesh enhanced neovessel formation, and increased tissue deposition and incorporation, with subsequent reduction of peritoneal adhesion and recurrence rate.

[Purpose] This study systematically reviewed the antalgic effects of non-invasive physical modalities (NIPMs) on central post-stroke pain (CPSP). [Subjects and Methods] Clinical studies were sought on September 2015 in 10 electronic databases, including Medline and Scopus. The searching strings were “central pain and stroke” and “treatment, and physical or non-pharmacological”. The inclusion and exclusion criteria were set for screening the clinical articles by two reviewers. Pain scores on visual analog scale in an article were used as the outcome measure for resulting judgment. The NIPMs intervention summarized from the eligible articles was rated from Levels A to C according to Evidence Classification Scheme for Therapeutic Interventions. [Results] Over 1200 articles were identified in the initial searches and 85 studies were retrieved. Sixteen studies were eligible and judged. Caloric vestibular stimulation (n=3), heterotopic noxious conditioning stimulation (n=1), and transcutaneous electrical stimulation (n=1) were rated below Level C. Transcranial direct current stimulation (TDCS; n=2) and transcranial magnetic stimulation (TMS; n=9) were rated as Level B. [Conclusion] The findings suggest that TMS and TDCS were better than other treatments for CPSP relief but the studies were of insufficient quality.

水越伸は,その著書『メディアの生成』のなかで,無線電話という新しい技術がラジオ放送という新しいメディアに結実していく過程を多面的に記述した。そこにおいては,新しいメディアは,まずは既存のメディアの延長上でとらえられ,社会的に共有される。しかしながら,それが展開されるうちに,当初のビジョンは実態とのズレを生じる。そして,そのズレを原動力として,新しいメディアの生成が導かれる。本稿では,水越のこの観察を紹介するとともに,それが新しい秩序(思想,理論,様式,など)の生成機構に関して高い一般的意義を有すること,とりわけ自然科学における基本理論の形成過程ときわめてよく対応することを示した。また,このような創造過程に関わる日本社会の問題点を論じた。Shin Mizukoshi described in his book, "Formation of Media" (in Japanese, Tokyo, 1993), the detailed process that a new technology, wireless telephone, developed into a new medium, radio broadcasting. In this process, the new technology was first accepted in the framework of the existing media, and shared in the society. However, in the development process, the first vision about the technology showed inconsistencies with the actual situation, which drove the technology into the formation of the new medium. The present paper shows the general significance of Mizukoshi's observation, in particular its great similarity with the process of the formation of fundamental theories in sciences. The problems of Japanese society concerning such creation processes were also discussed.

The atypical cutaneous tumor of a 9-year-old mixed breed female dog was examined. The tumor was well-demarcated and histologically composed of a trichoblastic area, tricholemmal area and apocrine glandular area. Neoplastic cells in trichoblastic area and tricholemmal area had PAS-positive granules in the cytoplasm and were positive for pan-cytokeratin, cytokeratin 5/6, 14 and 19 and p63. Neoplastic cells in trichoblastic area were also positive for cytokeratin 15 and CD34. Neoplastic cells in apocrine glandular area were positive for pan-cytokeratin and cytokeratin 7, 18 and 19. Myoepithelial cell proliferation with osteocartilaginous metaplasia was observed in this area. Since neoplastic cells showed multiphenotypic differentiation for hair follicles and apocrine glands, the present case was diagnosed as a cutaneous mixed tumor.

Background: Fifteen 3-styrylchromones were subjected to quantitative structure?activity relationship (QSAR) analysis based on their cytotoxicity, tumor selectivity and anti-HIV activity, in order to explore their biological activities. Materials and Methods: Cytotoxicity against four human oral squamous cell carcinoma (OSCC) cell lines and three human oral normal cells was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. Tumor-selectivity was evaluated by the ratio of the mean CC50 (50% cytotoxic concentration) against normal human oral cells to that against OSCC cell lines. Anti-HIV activity was evaluated by the ratio of CC50 to EC50 (50% cytoprotective concentration from HIV infection). Physicochemical, structural and quantum-chemical parameters were calculated based on the conformations optimized by the LowModeMD method followed by the density functional theory (DFT) method. Results: All 3-styrylchromone derivatives showed moderate-to-high tumor selectivity. Especially, compounds that have a methoxy group at 6-position of the chromone ring and hydroxyl group at 4'-position of phenyl group in styryl moiety [11] showed the highest tumor-selectivity. On the other hand, their cytotoxicity against normal cells showed good correlation to the descriptors that reflect hydrophobic interaction and molecular shapes. Conclusion: Multivariate statistics with chemical descriptors for the location of substituted group, molecular shape and electrostatic interaction may be useful for designing the most favorable compound with higher tumor selectivity.
