  • A new species of Neosartorya was recovered during investigation of the fungal community in soil samples collected from different locations in Korea; Neosartorya aureola KNU14-7 was isolated for the first time from field soil in Korea and identified based on the internal transcribed spacer region of rDNA and morphological characteristics. The species has not been officially reported from Korea and we report it here with description and figures.

  • We report on the development of ferronematic liquid crystals, new materials that consist of a dilute suspension of ferroelectric particles in a nematic liquid crystal host. The particles share their ferroelectric properties with the nematic liquid crystal and impose a spontaneous dielectric polarization of about 10 nC/$cm^2$ to the entire medium, typical for many ferroelectric liquid crystals. As expected, these new materials have enhanced dielectric anisotropy and are sensitive to the sign of an applied electric field. The potential of their use in a number of devices are discussed.

  • Phosphate glasses were prepared by melting quenching process, and glass formation and dissolution properties were studied. The glass forming region in the $K_2O-CaO-P_2O_5$ system is quietly agreed with the report by Mazurin OV et al. with $M_2O-M'O-P_2O_5$ system (M : monovalent cation, M'divalent cation). Conditionally these glasses have solubility from absorbing the moisture or water and then release elements with trace elements, and the thermal and chemical properties were controllable by the $CaO,\;K_2O,\;P_2O_5$ contents. In the abnormal glass properties, this paper showed the possibility the present glasses can be a good candidate for one component of the slow released agriculture fertilizer.

  • Transverse mandibular deficiency has a many problem in growing patients. Therefore, Mandible symphysis widening is recommended. A new surgical technique has been developed to widen the mandible. The purpose of this study is to report the effect of mandibluar symphyseal distraction osteogenesis by use of bone-borne type distractor. The surgical procedure was accomplished under general anaesthesia with step-line osteotomy. Bone-borne type distractor was used to generally widen the mandible. The expansion achieved in the mandible was 8.31mm at the device, 6.32mm at the canines, 4.06mm at the first molars. The symphyseal distraction gaps were bridged by new bony regeneration. Mandibular symphseal distraction osteogenesis increased mandibular arch width, stabilized occlusion, and corrected dental crowding.

  • Generation of hydrogen and oxygen gas from water is mostly accomplished by electrolysis. In this report, a scheme is presented regarding the gas generation based on plasmolysis. Unlike electrolysis water dissociation by electrical discharge (plasmolysis) requires a high voltage to cause either electron emission or electron capture, and subsequent ionization of involved molecular species. When electrical discharge is initiated between electrodes separated by water-vapor interface, a very large electric field(~100kV/cm) is developed at the tip of the electrode placed in the vapor phase. It is found that the efficiency of plasmolysis depends on the polarity of the electrode placed in the vapor phase. Also presented is the scheme of hydrogen and oxygen generation by such electrical discharge.

  • It is very important that we try to keep our traditional historical assets in the original form for a long time. Seoggur-Am has a very long and old history of about 1200 years. Yet, for the past several years there are many factors ruinning this historical treasure. Recently, specialist are new scientifically examining Seoggur-Am and evaluating its current condition, If you only judge these historical assets from the exterior structural environmental approach your scientific conclusion will not be complete. No one has studied Seoggur-Am from the viewpoint of indoor environmental climate. Therefore, I have surveyed and prepared a report of investigation as well as countermeasure so to understand the impact of indoor environmental climate on Seoggur-Am. The purpose of this paper is to first survey the existing research data based on exterior structural environment. Secondly, closely evaluate the new data of Seoggur-Am from the viewpoint of indoor environmental climate.

  • We report twenty eight ichneumonid species new to Korea. These species belong to seven subfamilies. Among them five subfamilies, Diacritinae Townes, 1965, Microleptinae Townes, 1958, Orthocentrinae F$\ddot{o} $rster, 1869, Orthopelmatinae Schmiedeknecht, 1910, Phrudinae Townes and Townes, 1949, are newly introduced to Korean fauna. All specimens are based on the insect collection of animal systematic laboratory at the Yeungnam University Gyeongsan Campus. Photographs of habitus of newly recorded subfamilies, diagnosis of 28 species and host information are provided.

  • Xanthid crabs, decapod crustacean, with the black coloured fingers, are easily found under rocks or stones in the intertidal or subtidal zones. Two xanthids, Etisus laevimanus Randall, 1840 and Paraxanthias elegans (Stimpson, 1858), were newly reported in Korean waters as part of continuous taxonomic studies on crabs. The genus Paraxanthias Odhner, 1925 was also reported for the first time in Korea. Of these, the examined specimen of P. elegans showed eight feathery hairs on the subdistal tip of the first gonopod, which differs from the description of Dai and Yang at 1991. Here, the descriptions and illustrations of these species are provided. Korean Xanthoidea currently consists of 30 species belonging to 25 genera.

  • A licensing approach for new fuel design is propose. It includes the possible licensing options to be taken according to the level of significance of design changes. This approach can be applied on legal grounds of the AEA, Article 44.3 and Article 21, but implies that the related ERAEAs should be revised or other alternative regulatory guidelines should be prepared. However, it is not intended to invoke additional requirements but rather to streamline and formulate the current practice by using one of supplementary provisions of the AEA, Article 104.2 which is recently enacted for approval of the technical report on a special topic.

  • Exposure of the cardiac pacemaker is still a difficult problem associated with high morbidity. Grossly infected pacemaker systems had been required removal and insertion of a new system. It would highly desirable to develop a new method that could salvage an exposed well functioning unit because cardiac pacemaker is very expensive. We have experienced one patient with exposed well functioning cardiac pacemaker, which was relocated to contralateral subpectoral pocket and healed without complication. This relocation of the pacemaker to subpectoral pocket is less simple, expensive and should be considered as an alternative to complete replacement of unit.
