Almost of alternate computer access devices which assist people with disabilities to utilize the computer connected to computer by some cables or installed in as a S/W program. These devices have some spatial limitations to the people with disabilities, it can't guarantee the free and diverse access to the computer. For these reasons, in this paper, an Android-based mouse program for alternative computer access was developed. A people with physical disabilities who has some limitation of hand movements can use it in anywhere and anytime using only the fine motor skill of the upper limbs. The developed device recognizes the user's point touch and transforms it into the location of mouse cursor. The location information transferred to the computer via Bluetooth communication module equipped in smart devices. Also the group scanning method which can reduce the user's fatigue degree was employed and click, double click, drag & drop functions by hand's movements were equipped. The developed device will help the people with disabilities to use computer with brief touch and convenient operation without spatial limitation.

Tracheostomy may be used to assure airway protection in various clinical situation. It, as a known operation, has a history spanning 2000 years. The first clear account of a successful tracheostomy was recorded in 1546 by Brasavola. Until 1718 the term "bronchotomy" was used to describe the procedure. Heister then introduce the term "tracheotomy and this was later adopted and popularized by Trousseau about 1830. The term "tracheostomy" appeared in medical literature after 1820 and the two terms "tracheostomy" and "tracheotomy" are used interchangeably today. Indications include relief of upper airway obstruction, facilitation of pulmonary toilet, diminution of dead space and need for prolonged mechanical ventilation. The extent of indication of tracheostomy has a tendency to increase, thus oral and maxillofacial surgeons have some opportunities to face a situation that require tracheostomy. So, we reported retrospective study of 31 cases of tracheostomy patient in oral and maxillofacial surgery with reference review to reveal the significance of surgical skill and management capability of emergercy state maxillofacial surgery patients.

The survival of patients with gastric cancer is improved by early diagnosis and surgical treatment. However, there is no established treatment for locally recurrent cancer or cancer arising at an anastomotic site after total gastrectomy; further, most surgeons are reluctant to resect this type of cancer because of frequent systemic metastasis and there are few competent surgeons who have the skill to perform such an operation. We have experienced recurrent cancer at an anastomotic site after total gastrectomy: one patient had recurrent cancer and two patients had metachronous cancer. All these patients were operated on and the patients were discharged without any complications. All of them are alive at the time of this report. In some cases, good results could be expected for operating on recurrent cancer of an anastomotic site after previous total gastrectomy. So, we present here our experience along with a review of literatures.

IR(Institutional Repository) is an indispensable instrument for not only long time preservation of intellectual products but also for shifting commercial publishing company-dominated academic communication stream. In Korea, dCollection project of Ministry of education, science and technology has contributed on immediate, integrated circulation of distributed research products. dCollection is already one of the few integrating instrument for distributed academic resources, but it has not been university's voluntary instrument to announce their research accomplishments and to realize open access. On the other hand, Japanese government has promoted universities' IR operation through "Next generation infrastructure construction project." Even though distributing speed is relatively low, each university made ripe operating skill by their selves and realize its own purpose. This study comparatively analyzed policy and current status of Institutional Repository in Korea and Japan from various viewpoints. And also it proposed directions of development about Korean Institutional Repositories.

A track circuit has used stably more than 100 years for detecting train position, but solution of track circuit sort circuit incapacity due to a rust is necessary for side line in station yard, coast line and level crossing for conventional line in rural line. Domestically, Axle Counter System(ACS) has partially used for Hot Box System for high speed line and turnout for CBTC system. In contrast, most of countries has used ACS not only trunk line but also rural line and its application has increased for metro, electric car and industrial railway. In this paper, we has verified the operating status of ACS which installed with existing track circuit through log analsis to implement pilot application in mail track and turnout in station yard. And interface test with interlocking system has conducted at Obong shunting yard, as well as Cheongju station and has analyzed test result. Based on a test result, we made fail safe design, manufacturing skill and established system requirement specification for the smooth operation and maintenance.

A large number of MJO skill metrics and process-oriented MJO simulation metrics have been developed by previous studies including the MJO Working Group and Task Force. To assess models' successes and shortcomings in the MJO simulation, a standardized set of diagnostics with the additional set of dynamics-oriented diagnostics are applied. The Global Coupled (GC) model developed for the operation of the climate prediction system is used with the comparison between the GC2 and GC3.1. Two GC models successfully capture three-dimensional dynamic and thermodynamic structure as well as coherent eastward propagation from the reference regions of the Indian Ocean and the western Pacific. The low-level moisture convergence (LLMC) ahead of the MJO deep convection, the low-level westerly and easterly associated with the coupled Rossby-Kelvin wave and the upper-level divergence are simulated successfully. The GC3.1 model simulates a better three-dimensional structure of MJO and thus reproduces more realistic eastward propagation. In GC2, the MJO convection following the LLMC near and east of the Maritime Continent is much weaker than observation and has an asymmetric distribution of both low and upper-level circulation anomalies. The common shortcomings of GC2 and GC3.1 are revealed in the shorter MJO periods and relatively weak LLMC as well as convective activity over the western Indian Ocean.
