  • The aim of the study was to evaluate the performance of 3 calibration methods, modified partial least squares (MPLS), local PLS (LOCAL) and artificial neural network (ANN) on the prediction of chemical composition of forages, using a large NIR database. The study used forage samples (n=25,977) from Australia, Europe (Belgium, Germany, Italy and Sweden) and North America (Canada and U.S.A) with information relative to moisture, crude protein and neutral detergent fibre content. The spectra of the samples were collected with 10 different Foss NIR Systems instruments, which were either standardized or not standardized to one master instrument. The spectra were trimmed to a wavelength range between 1100 and 2498 nm. Two data sets, one standardized (IVAL) and the other not standardized (SVAL) were used as independent validation sets, but 10% of both sets were omitted and kept for later expansion of the calibration database. The remaining samples were combined into one database (n=21,696), which was split into 75% calibration (CALBASE) and 25% validation (VALBASE). The chemical components in the 3 validation data sets were predicted with each model derived from CALBASE using the calibration database before and after it was expanded with 10% of the samples from IVAL and SVAL data sets. Calibration performance was evaluated using standard error of prediction corrected for bias (SEP(C)), bias, slope and R2. None of the models appeared to be consistently better across all validation sets. VALBASE was predicted well by all models, with smaller SEP(C) and bias values than for IVAL and SVAL. This was not surprising as VALBASE was selected from the calibration database and it had a sample population similar to CALBASE, whereas IVAL and SVAL were completely independent validation sets. In most cases, Local and ANN models, but not modified PLS, showed considerable improvement in the prediction of IVAL and SVAL after the calibration database had been expanded with the 10% samples of IVAL and SVAL reserved for calibration expansion. The effects of sample processing, instrument standardization and differences in reference procedure were partially confounded in the validation sets, so it was not possible to determine which factors were most important. Further work on the development of large databases must address the problems of standardization of instruments, harmonization and standardization of laboratory procedures and even more importantly, the definition of the database population.

  • This study evaluated the standardization of the outpatient management process in several regions of South Korea. The hospital workers in the administration department of the different medical institutions that are registered with the Korean Hospital Association were surveyed. These institutions can be standard hospitals or hospitals greater in size. A summary of the research results are as follows. There was no significant correlation in their registration procedures in relation to the institution's founder, number of sickbeds, number of staff employed in the administration department, and average number of outpatients per day. On the other hand, the prepayment of medical fees occurred more frequently when the number of sickbeds was larger. In addition, there was no large difference in their appointment procedures in relation to those features. Nevertheless, the prepayment of medical fees accounted for 11.8 % of the entire payment in institutions with less than five hundred beds, while fifty percent of the payment was made in advance in larger institutions with five hundred or more beds. From this research, there was only a small difference among the institutions' outpatient management, but a notable difference was observed in their electronic data processing systems and facilities. Therefore, more financial support should be generated for the implementation of a more integrated process. As a follow-up study, to provide patients with quality medical services, it will be necessary to apply the standardized procedure to an actual medical institution and analyze the expected effect.

  • This paper describes a method of AAL(SSCOP) protocol conformance testing and its result analysis in ATM network. Terminal equipment(TE) that implements protocols for connecting ATM network shall be verified if appropriately implement by conformance testing. The protocol specifications and the testing methodology are recommended or standardized by international standardization organization(ITU-T, ISO, etc.). The ATM AAL (SSCOP) protocol which selected for describing conformance test procedure is standardized in ITU-T Q.2110 and ATM Forum UNI 3.1 which are same in contents. Also Testing standard like ATS for SSCOP is specified in ATM Forum 95-1459R2. Construction of conformance testing environment is necessary to coordinate in relations with standards, then testing must beexecuted at that environment and the results from the test system analyzed. For this, it is necessary to select any test case from standard for testing and to make ETS. The ETS is proted on the test system and conformance testing will execute on that system. Finally the result from the test system is to analyze. This conformance testing procedure is applicable to the same other test cases in SSCOP and protocols in any communcation networks.

  • With the development of information and communication technology, hospitals that electronically process and manage medical information of patients are increasing. However, if medical information is processed electronically, there is still room for infringing personal information of the patient or medical staff. Accordingly, in 2017, the International Organization for Standardization (ISO) published ISO TS 25237 Health Information - Pseudonymization[1]. In this paper, we examine the re - identification process based on ISO TS 25237, the procedure and the problems of our proposed method. In addition, we propose a new processing scheme that adds a re-identification procedure to our secure differential privacy method [2] by keeping a mapping table between de-identified data sets and original data as ciphertext. The proposed method has proved to satisfy the requirements of ISO TS 25237 trust service providers except for some policy matters.

  • This paper is a study of TPS Migration to a multi-purpose ATS which is used for functional testing of Avionics parts. The dedicated ATS used for the performance test of avionics parts has a lot of difficulties in domestic MRO companies that carry out maintenance of high-level avionics ranging from tens of thousands won to several hundreds of billions won. For this reason, in this paper, I have studied the procedure of TPS migration to use the wire-harness in generators used in A aircraft, which is a maintenance product using a dedicated ATS, as a general-purpose ATS. Through the proposed study, We confirmed the 100% performance verification after the TPS migration from the proprietary to the general purpose. It is possible to expand infinitely through the standardization of the procedure.

  • This essay talks about research of robust design for quality improvement of production procedure of Wet Etchant. It suggested the optimum design method in consideration of specific capability value that is the way to maximize the quality of product in the production system by using Daguchi parameter design method while finding factors affecting product quality with analysis of production system of product A from producer D. Also, it set long term of 6months as noise factor and let it to be the robust design that can find the optimum condition of control factor that is dull to the changes of each month, that is the change in noise factor. The control factor which affects the product quality is decided as combination method, temperature of raw material, combination time and as there are too many possibilities for combination methods, we performed 4 methods first based on previous research data then derived three ways with product that passed SPEC and set as the factor. As a result of application of optimum production procedure suggested in this essay to the actual production process with its standardization, there was a effect of drop of more than 10particles in comparison to the particle number of previous product and also it brought the effect that resulted the stable number of particle of under 30 that is what the client company suggested.

  • To prove the integrity of digital evidence on the investigation procedure, the data which is using the MD 5(Message Digest 5) hash-function algorithm has to be discarded, if the integrity was damaged on the investigation. Even though a proof restoration of the deleted area is essential for securing the proof regarding a main phase of a case, it was difficult to secure the decisive evidence because of the damaged evidence data due to the difference between the overall hash value and the first value. From this viewpoint, this paper proposes the novel model for the mobile forensic procedure, named as "E-Finder(Evidence Finder)", to ,solve the existing problem. The E-Finder has 5 main phases and 15 procedures. We compared E-Finder with NIST(National Institute of Standards and Technology) and Tata Elxsi Security Group. This paper thus achieved the development and standardization of the investigation methodology for the mobile forensics.

  • It is desirable that implementation assessment (IA) should be carried out efficiently in order to make successful progress of Total Maximum Daily Load (TMDL) in watershed management. There are many difficulties in the process of the implementation assessment because of the early stage in the application of TMDL in Korea. This study reviewed the present status of IA and proposed the methodology of its improvement such as flexible application of TMDL ledger, and standardization of assessment index and criteria. The deficient time for assessment period could be corrected by the consideration of the post-procedure after the submission of IA report.
