With the growing popularization of small crafts, the accidents that happen among such crafts are also drawing increasing attention, according to the marine accident data released by the Japan Coast Guard. In order to prevent possible navigation accidents, the authors considered that besides sharing information from land by the coast office broadly, man- agers on land can also watch out and give appropriate advice for operators in crafts one-to- one. This paper discusses the technical issues of developing virtual globe-based （Google Maps/Earth geographic information system （GIS）） 3D visualization stand-alone software for small craft navigation assistance in the aim to facilitate the safety and sufficiency of small crafts in the near sea. The system was developed using web services and object-oriented programming disciplines to support the integration of a virtual global framework, GPS, and real-time imaging data. The authors have also developed data processing programs that are glued together with C# language, JavaScript language, National Marine Electronics Association （NMEA） instance data, and keyhole markup language （KML） data. Experiments for evaluating the framework have been made around the near coastal area. The perfor- mances and deficiencies are discussed in this paper. In order to evaluate the validity of the performance and the functionality of the system, authors conducted a questionnairesurvey among third year students of the Voyage Course at Kobe University. The evaluation of the system suggests valuable potential for the small craft navigation assistance system.

AIM To investigate the possible involvement of transient receptor potential vanilloid 1(TRPV1) in maturation of enteric glial cells(EGCs).METHODS Immunohistochemical and immunocytochemical techniques were used to analyze EGC markers in myenteric plexus(MP) as well as cultured MP cells and EGCs using TRPV1 knockout(KO) *** We detected TRPV1-immunoreactive signals in EGC in the MP of wild-type(WT) but not KO mice. Expression of glial fibrillary acidic protein(GFAP) immunoreactive signals was lower at postnatal day(PD) 6 in KO mice, though the difference was not clear at PD 13 and PD 21. When MP cells were isolated and cultured from isolated longitudinal muscle-MP preparation from WT and KO mice, the yield of KO EGC was lower than that of WT EGC, while the yield of KO and WT smooth muscle cells showed no difference. Addition of BCTC, a TRPV1 antagonist, to enriched EGC culture resulted in a decrease in the protein ratio of GFAP to S100 B, another EGC/astrocyte-specific marker. CONCLUSION These results address the possibility that TRPV1 may be involved in the maturation of EGC, though further studies are necessary to validate this possibility.

引入厚度偏差Δd,修正了薄膜透射率表达式.基于Ag/AAO纳米有序阵列复合结构实验透射光谱(500—2700nm)的两条极值包络线,定义了一个优化函数,结合最优化数值算法尝试确定具有较强吸收的Ag/AAO纳米有序阵列复合结构的等效光学参量.由此计算了该结构的等效折射率n、等效消光系数k、平均等效厚度-d以及厚度偏差Δd.该方法对Ag/AAO纳米复合结构平均等效厚度的相对计算误差仅为0.3%,与实测厚度基本一致,且Ag/AAO纳米复合结构的模拟透射谱与实验透射光谱在500—2700nm波段范围内相符.这表明该计算方法可有效确定Ag/AAO纳米复合结构的等效光学参量,并与实验结果是自洽的.

＜正＞Uveitis and intraocular inflammation （Ⅱ） sometimes run a chronic course with recurrence. Visual prognosis is poor if correct diagnosis and proper management are not done. It is well known that the etiology and cause differ from one population to another. Therefore, it is important for us Asian to know what are the major uveitis entities in Asian populations.
