A Multi-Vision needs an image adjust of each product to make the same picture quality for all products when it's installed. Owing to this reason need individual control. This document request indivisual control method for each product with the Remote controller. To realize this method need make Set ID and Picture ID on the UI and need daisy chain of cable to connect Remocon code(IR Signal) In to Out, After allocation the Set ID for each product. Picture ID of the product which want to change picture quality make equal to Set ID. And the product which is same Set ID and Picture ID is only controlled through decoding of Remocon code to Scaler.

This paper studies a method for making more efficient classification rules in the ID3 using the rough set theory. Decision tree technique of the ID3 always uses all the attributes in a table of examples for making a new decision tree, but rough set technique can in advance eleminate dispensable attributes. And the former generates only one type of classification rules, but the latter generates all the possibles types of them. The rules generated by the rough set technique are the simplist from as proved by the rough set theory. Therefore, ID3, applying the rough set technique, can reduct the size of the table of examples, generate the simplist form of the classification rules, and also implement an effectie classification system.

A stochastics process $X = {X(t) : t \in T}$, with an index set T, is said to be infinitely divisible (ID) if its finite dimensional distributions are all ID. An ID process X is said to be a stochastic integral process if $X = {X(t) : t \in T} =^D {\int f_td\Lambda : t \in T}$ where $f : T \times S \to R$ is a deterministic function and $\Lambda$ is an ID random measure on a $\delta$-ring S of subsets of an arbitrary non-empty set S with the property; there exists an increasing sequence ${S_n}$ of sets in S with $U_n S_n = S$. Here $=^D$ denotes equality in all finite dimensional distributions.

Firstly, this dissertation suggests the tag ID transfer method using two-dimensional arrangement. Secondly, provide better and stable security system compare to existing one by transferring tag; ID using established two-dimensional arrangement. Thirdly, provide operating module, which possible to descramble two-dimensional arrangement, with a character set when descrambling in a tag and a server. Lastly, suggest safe key transfer using a character set and two-dimensional arrangement. In order to embody suggested system and assess, transferred two-dimensional arrangement several times to carry out the experiment. Confirmed that it is impossible for suggested system to decode key patterns compare to existing RFID systems.

We propose a Z-HBT line coding for a LED-ID system. Z-HBT line coding is defined as follows. First, we apply half bit transition to one bit. Second, we decode encoded bits using difference of bit transition level in one bit duration. As a result, we obtain advantages about synchronization problem and noise effect mitigation at the receiver. We set up outdoor the LED-ID simulation environment. At simulation results, we show 2-3dB gain as compared with existing line coding schemes. The results of the paper can be applied to design and implementation of LED-ID systems for indoor wireless multimedia services.

For stable silkworm breeding and high-quality sericulture product production, the detection of Pebrine disease in silkworm eggs is critical. Current diagnostic methods can be timeconsuming and complex. This study aimed to develop a simplified and rapid diagnostic method using loop-mediated isothermal amplification (LAMP) technology to detect pebrine infection in silkworm mother moths. Eight primer candidates targeting the ribosomal gene region of microsporidia were designed and evaluated for specificity and detection sensitivity. A simplified nucleic acid extraction method was established, and isothermal amplification was performed using the selected primers. Of these, primers ID30 and ID45 showed no polymerization, while ID5, ID18, and ID76 exhibited nonspecific reactions, making them unsuitable. Primers ID1, ID6, ID45, and ID82 successfully amplified DNA only in the presence of pebrine, with ID82 demonstrating the best reproducibility and sensitivity, detecting as low as 2.5 pg/ul of DNA through electrophoresis and 5 pg/ul via a colorimetric change with phenol red. The entire process, from nucleic acid extraction to detection, was completed within 60 min. The use of the ID82 primer set in LAMP technology offers a promising and efficient approach for the rapid diagnosis of pebrine disease, potentially enhancing quality control in sericulture.

Chikungunya fever is an arboviral disease caused by the Chikungunya virus (CHIKV). The disease has similar clinical manifestations with other acute febrile illnesses which complicates differential diagnosis in low-resource settings. We aimed to develop a rapid test for CHIKV detection based on the nucleic acid lateral flow immunoassay technology. The system consists of a primer set that recognizes the E1 region of the CHIKV genome and test strips in an enclosed cassette which are used to detect amplicons labeled with FITC/biotin. Amplification of the viral genome was done using open-source PCR, a low-cost open-source thermal cycler. Assay performance was evaluated using a panel of RNA isolated from patients' blood with confirmed CHIKV (n = 8) and dengue virus (n = 20) infection. The open-source PCR-NALFIA platform had a limit of detection of 10 RNA copies/ml. The assay had a sensitivity and specificity of 100% (95% CI: 67.56% - 100%) and 100% (95% CI: 83.89% - 100%), respectively, compared to reference standards of any positive virus culture on C6/36 cell lines and/or qRT-PCR. Further evaluation of its performance using a larger sample size may provide important data to extend its usefulness, especially its utilization in the peripheral healthcare facilities with scarce resources and outbreak situations.

본 논문은 IEEE 802.11 네트워크 환경에서 MN(Mobile Node)이 핸드오버를 수행하기 전에 미리 이동 정보를 예측함으로써, 유연하게(Seamless) 서비스를 계속 받을 수 있는 예측 방법을 제안한다. 특히, MN이 속한 AP(Access Point)가 중첩된 상황에서 발생할 수 있는 여러 가지 문제점을 해결한다. MN은 이동성 패턴 레코드를 저장하고, 또한 각 이웃 AR(Access Router)은 AP의 AP-ID(BSSID, Basic Service Set ID)와 채널을 저장한다. MN이 AP의 영역의 경계를 벗어나기 전, 새로운 AP로부터 AP-lD를 획득하면, MN이 저장하는 이동성 패턴 레코드에서, AP-ID와 맞는 정보를 비교하여 확률이 높은 AP를 선택한다. 이러한 정보를 PAR(Previous Access Router)에게 정보를 보내어 신속하게 새로운 링크에서 서비스를 받을 수 있음으로써 손실.지연을 최소화 할 수 있다.

In this paper, we design and implement a product information guidance system Based on BLE beacons. This system is designed to provide various functions such as contactless entrance service through mobile ticket, seat guidance service, event push service, content push service, and public service. This system consists of three modules: a beacon recognition module, a server linkage module, and a content transmission module. The beacon recognition module implements a function of transmitting a specific ID of a nearby beacon when a customer with a smartphone approaches the available service area. The server linkage module recognizes the beacon ID value, transfers it to the server, and implements the function to check the location of the server having the ID. The content transmission module implements a function of transmitting event or service information set at a corresponding location to a smartphone. The beacon-based product information guidance system implemented in this paper has the advantage of being able to quickly and easily implement various product information guidance systems.

In the present paper, we prove common fixed point theorems for single-valued and set-valued occasionally weakly compatible mappings in Menger spaces. Our results improve and extend the results of Chen and Chang [Chi-Ming Chen and Tong-Huei Chang, Common fixed point theorems in Menger spaces, Int. J. Math. Math. Sci. 2006 (2006), Article ID 75931, Pages 1-15].
