  • A type of symbiosis was previously described from nature in which the gametophytes of Laminariales were endophytic in filamentous red algae. Here we reconstruct this symbiosis for the first time in laboratory culture using zoospores of the kelp, Undaria pinnatifida, and the red alga, Aglaothamnion oosumiense. Zoospores of U. pinnatifida readily attached to A. oosumiense. In 48 h these spores germinated and the initial germ tube penetrated into the host cell wall leaving only an empty zoospore wall outside the host. Within ten days, four to five-celled endophytic gametophytes were present. Zoospores of Laminaria religiosa which were also inoculated into cultures of A. oosumiense rarely attached to the red alga and never became endophytic. Within ten days the free-living gametophytes of L. religiosa on cover slips became fertile and produced young sporophytes. These observations demonstrate the ability of U. pinnatifida to become endophytic, and show differences in host specificity among kelp species.

  • An aberrant right subclavian artery is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention. Ligation of the aberrant artery through a left thoracotomy has been advocated as the operation of choice. If development of vertebrobasilar insufficiency is anticipated, division and ligation of he aberrant artery and its anastomosis to the right common carotid artery or aortic arch are performed at a second operation. Experience with successful surgical treatment of a patient with an aberrant subclavian artery is described. A right thoracotomy incision was utilized for division of the subclavian artery and for reestablishment of arterial continuity with Dacron graft. Postoperative arteriography demonstrated a good reconstruction and normal blood flow was established to the right upper extremity.

  • As the Korea Sports Council and The Korean Olympic Committee (KOC) were integrated in June 2009, the Amended Articles expunged the applicable provisions of the e Korea Sports Arbitration Committee (KSAC), which was established in Markch 2006. To successfully host international sports events, such as 2014 Incheon Asian Games and PyeongChang 2018 Winter Olympics, the Korea Sports Arbitration Committee (KSAC) must be restored immediately. In this sense, this thesis places emphasis on the necessity of precise legal basis with the purpose of the revitalization of sports dispute settlement as well as the enhancement of the Korea Sports Arbitration Committee.

  • Patients with severe mental challenges are often subjected to extensive dental problems. Their impaired communication and lack of cooperation unable to receive timely dental treatments, which deteriorates their adverse oral conditions. In spite of a limited time frame, well-planned comprehensive treatments can be delivered in an one-day operation setting under general anesthesia. This multidisciplinary treatment regimen primarily comprises of single-visit endodontics, direct bonded restoration, periodontal treatment, and surgical extraction. Further, one or two additional visits for prosthetic procedures are able to accomplish functional reestablishment and esthetic enhancement. This article discusses on clinical managements for severely mentally challenged patients under a single-day operation.

  • Survey shows that temperature accounts for 90.6% of dissatisfaction in general hospital environment. In order to improve this situation, operation and thermal data of S hospital collected in 2006 are analyzed. The objective of this study is to find optimum fiducial temperature that minimizes occupants' complaints using 6 sigma method.

  • Purpose: To ensure good quality munitions, we require quantitative risk management and optimal risk management of system characteristics. Methods: Failure mode and effects analysis (FMEA) is a widely used technique to assess or to improve reliability of products at early stage of design and development. Traditionally, the prioritization of failures for corrective actions is performed by developing a risk priority number (RPN). Results: This paper reestablishes an effective methodology for prioritization of failure modes in FMEA procedure. Revised evaluation criteria of RPN are devised. Conclusion: To verify the proposed methodology, it is applied to RPN evaluation for K21 infantry combat vehicle.

Effectiveness and Balance of Compulsory and Voluntary Safety Certification of Industrial Machines and Devices (산업용 위험기계·기구 의무 및 임의 안전인증의 효과 및 균형)

  • This study first focuses on the quantitative evaluation of both compulsory and voluntary safety certification of industrial machines and devices. Based on the results of statistical analysis, effectiveness of those safety certifications were confirmed. In order to reduce both the frequency and the strength of industrial accidents associated with industrial machines and devices, major target of safety regulations needs to be shifted from users to manufacturers. Adjustment of industrial machines and devices which are subject to compulsory safety certification and implementation of risk assessment are further suggested. As for the voluntary certification, reestablishment of the concept of voluntary safety certification and balance between compulsory and voluntary certifications is discussed. Voluntary safety certification is further suggested as a mean to manage safety of industrial machines and devices which are not subject to any safety regulations.

  • The surgical treatment of annuloaortic ectasia falls into two basic categories, depending on the management of the coronary artery ostia and the sinus of Valsalva. The conventional method, first suggested by Groves, Wheat and their associates, employs a supracoronary graft for the treatment of aneurysm and conventional valve replacement. A more radical approach, that of Bentall and DeBono, uses a valve conduit from the aortic annulus to the distal extent of the aneurysm. This latter technique requires reimplantation of the coronary artery ostia for reestablishment of coronary artery blood flow. Recently we experienced a case of annuloaortic ectasia to which we applied the Bentall operation with the good postoperative result, and now we report this with literature review.

  • An aniline-utilizing microorganism identified as a species of Pseudomonas was isolated from soil contaminated highly with aniline and urea-herbicide. This strain was able to utilize aniline as the sole source of carbon and energy, and was shown to harbor a single large plasmid mediating the aniline assimilation. Subsequent plasmid-curing of this bacterium resulted in the abolishment of the aniline utilizing phenotype and the loss of catechol-C2,3O-oxygenase. The reestablishment of the plasmid, denoted pB10, in cured Pseudomonas sp. via filter surface mating, resulted in restoration of the aniline assimilation abilities and enzyme activity.

  • Following the emergency work in Fukushima Daiichi nuclear power plant, more attention was paid for the radiation protection of workers working under severe accident condition. The protection procedure for the emergency workers, including the on-site emergency center, the seismic isolated building and the reestablishment of the radiation protection framework were analyzed to investigate drawbacks and deficiencies which led to adverse effects on the emergency planning and on emergency workers' health and comfort. Those drawbacks were identified and studied, and then suggestions were made to enhance the emergency working condition to avoid any future problems during severe accident emergency work and management.
