Software compliance is an essential process when Open Source Software is included in software development to avoid such as license violation issue. However, analyzing quite big software which involves many developers requires enormous time and hard difficulty. To resolve these kinds of problem, SPDX formalizes and standardize the metadata about the software package. When the use of SPDX is activated, software package analysis would be simple and could contribute fair Open Source Software distribution. In this paper, we develop blockchain based SPDX distribution platform which fulfills the requirement of SPDX lifecycle to provide SPDX database which does not depend on particular centralized service but serve as distributed ledger and control by user's certification and their purpose. Moreover, to contribute invigoration of blockchain based SPDX distribution platform, we develop SPDX document generation plug-in for integrated development environment such as Visual Studio.

In this paper, we describe the design and performance of a prototype multi-rotor unmaned aerial vehicle( UAV) platform featuring an inertial measurement unit(IMU) based autonomous-flying for use in bluetooth communication environments. Although there has been a fair amount of study of free-flying UAV with multi-rotors, the more recent trend has been to outfit hexarotor helicopter with gimbal to support various services. This paper introduces the hardware and software systems toward very compact and autonomous hexarotors, where they can perform search, rescue, and surveillance missions without external assistance systems like ground station computers, high-performance remote control devices or vision system. The proposed system comprises the construction of the test hexarotor platform, the implementation of an IMU, mathematical modeling and simulation in the helicopter. Furthermore, the hexarotor helicopter with implemented IMU is connected with a micro controller unit(MCU)(ARM-cortex) board. The micro-controller is able to command the rotational speed of the rotors and to get the measurements of the IMU as input signals. The control simulation and experiment on the real system are implemented in the test platform, evaluated and compared against each other.

Background: An independent medical examination (IME) is a critical process for awarding reparation for injury. However, conducting an IME in pain medicine is very difficult, not only because pain is a subjective symptom, but also because there are no proper objective methods to demonstrate it. This study was conducted to compare IME reports and the court decisions on the disability status of the patients. Methods: We analyzed 79 IME reports and 25 corresponding court decisions on the disability status of patients. The diagnoses, causal relationships between the patients' status and the trauma, McBride's degree of disability, the American Medical Association's impairment ratings, the estimated annual cost for future treatment, and the necessity of care-giving were compared and analyzed. Results: The diagnoses in the 79 cases were complex regional pain syndrome (CRPS) type I (58 cases), CRPS type II (7 cases), peripheral neuropathy (5 cases), myofascial pain syndrome (4 cases), herniated intervertebral disc (2 cases), and fibromyalgia (1 case). The types of accidents were road traffic accidents (50 cases), military injuries (14 cases), industrial accidents (11 cases), and others (4 cases). The IME reports and the court decisions stated considerably different McBride's degrees of disability (P = 0.014). However, there was no significant difference in the estimated cost for future treatment between the IME reports and the court decisions (P = 0.912). Conclusions: IME reports should be accurate, fair, and based on objective findings. Feedback on IMEs from the court decisions is helpful for reference use.

Background: Millard's rotation-advancement repair, which is used by many surgeons, can make a natural philtral column, but most surgeons use a modification of the rotation-advancement flap. The purpose of this article is to introduce a modification utilized by the authors and to provide detailed surgical procedure. Methods: We retrospectively reviewed 82 patients' medical records and presented surgical technique and outcomes. The main features of the authors' strategy are emphasizing horizontal length of the lip, orbicularis oris muscle duplication for improving the definition of the philtral column, overcorrection of domal portion than the non-cleft side in order to compensate for the recurrence during growth. Two judges rated two times the appearance of the patients' nose and lip using Asher-McDade aesthetic index. Intra- and interobserver reliabilities were determined using Cohen's kappa statistics. Results: All patients recovered eventually after surgery; however, two patients have a minor complications (wound infection in one patient, wound disruption due to trauma in the other patient). The improvement of the aesthetic results can be achieved with this modified Millard technique. Total mean scores of the Asher-McDade index was 2.08, fair to good appearance. The intraobserver reliabilities were substantial to almost perfect agreement and the interobserver reliabilities were moderate to almost perfect agreement. Conclusion: We modified Millard method for repair of complete unilateral cleft lip. The surgical outcomes were favorable in long-term follow-up. We hope our technique will serve as a guide for those new to the procedure.

Dental prosthetic restoration shows a big difference of cost per itemized unit depending on the size of dental labs, facility standard, manpower, and performance. Even the same dental labs have distinctive cost according to manufacturing performance, inflation, and the number of workers. However, in apite of such a change of circumstances, it appears to be quite stable in the relative cost per itemized unit unless the manufacturing trend of particular item changes dramatically. Therefore, if the relative number of cost per itemized unit, which is produced by costing, is indicated, we are able to utilize it effectively as a standard wage estimate. If the wage of dental prosthetic restoration is determined on the basis of cost, it is desirable that the relative value of cost and that of wage are identical. But, by means of comparative analysis, since the relative value of wage reveals mostly lower than that of cost depending on an item, it is considered that the wage is not reflecting the cost approproately. Due to the subdivision and the profession of medical technology, the new development of wage items for dental prosthetic restoration is required. This means that the need for the establishment of new wage items should be presented as the general concept of dental prothetic restroation changes and the level of pathologic technology increases. The current wage structure has differences in the degree of difficulty accroding to unit items and in the cost factors. Nevertheless, the differences are not reflected enough to the wage, so there is potential to lower the medical quality through the use of low-proce materials to avoid the increase of cost and the work process which skips a manufacturing step. The new items of dental prosthetic restoration also increases, but the development of proper numerical value system is not supported. Thus, the right proce is set mostly by applying to the wage of a similar item. Since most wages are established by an individual agreement between the dental clinic institute and the dental labs, the propriety of wage level lacks. Therefore, it is urgent to provide and promote the system of a fair work charge by a standard cost which can be applied to all medical institute.

Purpose: We reconstructed the skin defect of lower legs exposing muscles, tendons and bone with fasciocutaneous sural artery flap and report our cases. Materials and Methods: Between March 2005 and September 2006, 8 cases of skin defect were reconstructed with fasciocutaneous sural artery flap. Defect site were 4 case of ankle and foot and 4 cases of lower leg. The average defect size was $4{\times}4\;cm^2$. There were 5 men and 3 women and mean age was 52.2 years. We evaluated the viability of flap, postoperative complication, healing time, patient's satisfaction. Results: There was no flap failure in 8 cases. But recurrent discharge in 2 cases was healed through several times adequate debridement and delayed suture without complication. Flap edema may be due to venous congestion was healed through leg elevation and use of low molecular weight heparin. Mean time to heal the skin defect was 4 weeks. No infection and recurrence in follow up period. Cosmetic results as judged by patients were that 5 cases are good and 3 cases are fair. Conclusion: Sural artery flap is good treatment method among the numerous methods in the cases of skin defect, with soft tissue exposed, which is not covered with debridment and skin graft. Sural artery flap is useful method for the skin defect of lower legs because it is simple procedure, has constant blood supply and relatively good cosmetic effect.

There are two concepts of division: measurement division and partitive or fair-sharing division. Students are expected to understand comprehensively division algorithm in both contexts. Contents of textbooks and teachers' guidebooks should be suitable for helping students develop comprehensive understanding of algorithm for whole-number division in both contexts. The results of the analysis of textbooks and teachers' guidebooks shows that they fail to connect two division contexts with division algorithm comprehensively. Their expedient and improper use of two division contexts would keep students from developing comprehensive understanding of algorithm for whole-number division. Based on the results of analysis, some ways of improving textbooks and teachers' guidebooks are suggested.

A arrival of u-teaming paradigm requires many u-teaming system and model that is varied and support to distance education, Accordingly, the distance education system in u-learning environment has attracted a fair amount of critical attention. However there remain many questions, as yet unresolved, such as it is difficult to maintain interaction between tutor and learner, the construction of system is a great expense to them, a tutor, who manages the system, lacks technologic background, in most current distance education system. To solve these problem, some preliminary observations have to be made first: to keep teaming process in situation that it is unconnected with tutor, to construct the system economically, and to make to be easy-to-use. Therefore, in this paper, we develop the 'Intelligent U-Learning System using Cyber Tutor', which includes the conception of u-learning such as mobility, immanency, supports to keep learning without real tutor by cyber tutor, and removes technological and economical costs, verify the validity.
