This study aims to present ways to enhance the stabilization of electronic medical records, ensure the commitment to filling in information of the medical record and improve the overall quality Electronic Medical Record(EMR) information. For that purpose, the present state of the incomplete record rate and the doctor's satisfaction in Electronic Medical Record(EMR) have been surveyed by comparing and analyzing Paper-based Medical Record(PMR) and Electronic Medical Record(EMR). The survey was conducted on 31 doctors in charge of EMR system and each PMR and EMR inpatients were collected for a period of 5 months and analyzed. The results showed that the doctor's satisfaction level was higher for EMR, and the rate of incomplete record appeared to be lower in EMR in departments of both internal and external medicine. In this context, it can be said that the higher efficiency of EMR helped accomplish the increase in commitment to completing medical record information and improve the quality of the data.

Key agreement protocol is a fundamental protocol in cryptography whereby two or more participants can agree on a common conference key in order to communicate securely among themselves. In this situation, the participants can securely send and receive messages with each other. An adversary not having access to the conference key will not be able to decrypt the messages. In this paper, we propose a novel identity-based authenticated multi user key agreement protocol employing a symmetric balanced incomplete block design. Our protocol is built on elliptic curve cryptography and takes advantage of a kind of bilinear map called Weil pairing. The protocol presented can provide an identification (ID)-based authentication service and resist different key attacks. Furthermore, our protocol is efficient and needs only two rounds for generating a common conference key. It is worth noting that the communication cost for generating a conference key in our protocol is only O($\sqrt{n}$) and the computation cost is only O($nm^2$), where $n$ implies the number of participants and m denotes the extension degree of the finite field $F_{p^m}$. In addition, in order to resist the different key attack from malicious participants, our protocol can be further extended to provide the fault tolerant property.

Usually, partailly balanced incomplete block design have been used a parametric design that make blocks of complete diallel cross. For that we use triangular PBIBD as parametric design, we have to find triangular PBIBD with corresponding parameters. Using the theorem that dual design of balanced incomplete block design with special parameters becomes triangular PBIBD, we can design block complete diallel cross without finding new triangular PBIBD. In this paper, we provided the plan and design satisfying such block complete diallel crosses.

This paper deals with a method for intrablock anlaysis of balanced incomplete block designs on the basis of projections under the assumption of mixed effects model. It shows how to construct a model at each step by the stepwise procedure and discusses how to use projection for the analysis of intrablock. Projections are obtained in vector subspaces orthogonal to each other. So the estimates of the treatment effects are not affected by the block effects. The estimability of a parameter or a function of parameters is discussed and eigenvectors are dealt for the construction of estimable functions.

This study was prepared to optimize $\alpha$-azuki bean powder content by sensory evaluation method when manufacturing bread with added $\alpha$-azuki bean powder. These sensory characteristics were designed to investigate sensory evaluation about appearance, color, texture, taste and overall acceptability of small red bean bread by balanced incomplete block design. According to evaluated mean of adjusted treatments, appearance was represented high value in bread with added 3% and 6% $\alpha$-azuki bean powder than bread without $\alpha$-azuki bean powder. Bread without $\alpha$-azuki bean powder was revealed maximum sensory score value of color among whole treatments and vread with added 6% $\alpha$-azuki bean powder was revealed second highest sensory value. As $\alpha$-azuki bean powder content increased, sensory score of texture, taste and overall acceptability increased. and bread added 12% $\alpha$-azuki bean powder revealed maximum sensory score. On the results of this research about sensory characteristics for manufacturing bread with added $\alpha$-azuki bean powder, bread with added $\alpha$-azuki bean powder was considered optimum when12% $\alpha$-azuki bean powder was added wheat flour because of highest score of texture, taste and overall acceptability in spite of lower score of appearance and color.

Bechhofer and Tamhane(1981) developed a theory of optimal incomplete block designs for comparing several treatments with a control. This class of designs is appropriate for comparing simultaneously $p{\geq}2$ test treatments with a control treatment (the so-called multiple comparisons with a control (MCC) problem) when the observations are taken in incomplete blocks of common size $K{\<}p+1$. In this paper we want to extend to partially BTIB designs with two associate classes for the MCC problem. We propose a new class of incomplete block designs that are partially balanced with respect to test treatments. Because the class of designs that we consider is larger than the class of designs in Bechhofer and Tamhane and provides us with designs that improve on the optimal designs in their class. We shall use the abbreviation PBTIB to refer to such designs. We study their structure and give some methods of construction. Also we describe a procedure for making exact joint confidence statements for the MCC problem in PBTIB Designs with two associate classes. We study Optimality, Admissibility considerations in PBTIB designs with two associate classes.

This paper discusses how to use projections for the analysis of data from balanced incomplete block designs. A model is suggested as a matrix form for the interblock analysis. A second set of treatment effects can be found by projections from the suggested interblock model. The variance and covariance matrix of two estimated vectors of treatment effects is derived. The uncorrelation of two estimated vectors can be verified from their covaraince structure. The fitting constants method is employed for the calculation of block sum of squares adjusted for treatment effects.

Objective : This study is performed to evaluate the procedural complications, aneurysm occlusion rate, and mid-term outcome of endovascular treatments in intracranial aneurysms. Methods : We retrospectively investigated 135 patients with 161 cerebral aneurysms who were treated by endovascular means at our institute from March 1999 to December 2004. We statistically analyzed overall outcome, occlusion rate, and occurrence of complications according to the location, size, rupture history, and neck size of aneurysms. Results : Forty-nine patients [36.3%] had experienced acute intracranial or extracranial complications related to the procedure. Among these, there were 13cases of perforation of the aneurysm, 9 of local vasospasm, 8 of thromboembolism, 4 of coil migration, 3 of occlusion of parent vessels due to coil protrusion, and 1 of seizure. Extracranial complications occurred in 14cases including alopecia [9cases], femoral artery thrombosis [2cases], acute renal failure [2cases], and hypovolemic shock [1case]. One hundred twenty-six aneurysms [78.3%] had complete occlusion of the aneurysm and 35 [21.7%] incomplete occlusion at 6months angiographic follow-up. Postembolization clinical follow-up ranged from 1 to 60months [mean, 14.2months]. Seven of the 161 aneurysms underwent additional embolization and 2 incomplete embolized aneurysms required subsequent surgery. Conclusion : The procedural complications and incomplete occlusion rates are substantial. Therefore, endovascular treatment needs close and continued neurosurgical and neuroradiological concerns for the therapy of intracranial aneurysms.

In this paper we introduce a new circle detection algorithm for occluded on/off pupil and iris boundary extraction. The proposed algorithm employs 7-step processing to detect a center and radius of occluded on/off eye images using the property of the chords. The algorithm deals with two types of occluded pupil and iris boundary information; one is composed of circle-shaped, incomplete objects, which is called occluded on iris images and the other type consists of arc objects in which circular information has partially disappeared, called occluded off iris images. This method shows that the center and radius of iris boundary can be detected from as little as one-third of the occluded on/off iris information image. It is also shown that the proposed algorithm computed the center and radius of the incomplete iris boundary information which has partially occluded and disappeared. Experimental results on RGB images and IR images show that the proposed method has encouraging performance of boundary detection for pupil and iris segmentation. The experimental results show satisfactorily the detection of circle from incomplete circle shape information which is occluded as well as the detection of pupil/iris boundary circle of the occluded on/off image.

This study analyzes the problems of fire qualification information websites and job search websites due to incomplete information in the job search process and suggests an improvement plan. It has been confirmed that the main reason for the cost of job searching is incomplete information required for a job search and job search through existing analysis. As a result, it is suggested to construct a smooth information system for economic entities and to provide easy access to information by mitigating the incompleteness of information. Based on this, analysis of the problems of Korean qualifications in the firefighting realm reveals that there is a qualification holder information and a job information site, and a qualification holder management system is established but only information of either qualification acquisition information or employment information is provided. In addition, it is easy to access information through a qualification acquisition information and employment information site via the Internet, but there are inconveniences that qualification acquisition information and employment information are dualized. In order to improve this, it is necessary to build a new customized integrated qualification management system that covers existing Q-net qualification acquisition information and worknet employment information.
