Fast inspection of solder ball bumps in ball grid array (BGA) is an important issue in the flip chip bonding technology. Particularly, semiconductor industry has required faster and more accurate inspection of micron-size solder bumps in flip chip bonding, as the density of balls increase dramatically. In this paper, we describe an inspection approach of BGA balls by using 5-step ring illumination device and normalized cross-correlation (NCC) method. The images of BGA ball by the illumination device show unique and distinguishable characteristic contours by their 3-D shapes, which are called as "iso-slope contours". Template images of reference ball samples can be produced artificially by the hybrid reflectance model and 3D data of balls. NCC values between test and template samples are very robust and reliable under well-structured condition. The 200 samples on real wafer are tested and show good practical feasibility of the proposed method.

For the molecular detection of Sweet potaio feathery mottle virus (SPFMV) from diseased sweet potato plants, reverse transcription and polymerase chain reaction (RT-PCR) was performed with the use of a set of virus-specific primers to amplify an 816 bp product. The viral coat protein gene was selected for the design of the primers. No PCR product was amplified when Turnip mosaic virus, Potato vims Y or Cucumber mosaic virus were used as template in RT-PCR with the SPFMV-specific primers. The lowest concentration of template viral RNA required for detection was 10 fg. The vim was rapidly detected from total nucleic acids of leaves and roots from the virus-infected sweet potato plants as well as from the purified viral RNA by the RT-PCR. Twenty-four sweet potato samples were selected and analyzed by RT-PCR and restriction fragment length polymorphism (RFLP). RFLP analysis of the PCR products showed three restriction patterns, which resulted in some point mutations suggesting the existence of quasi-species for the vims in the infected sweet potato plants.

데이터베이스와 연동하는 웹 응용에 대한 수요가 비즈니스를 포함하는 모든 분야에서 급속히 증가하고 있다. 그러나 급증하는 수요에 비해 웹 응용의 작성 및 유지.보수에 많은 시간과 노력이 소요되고 있다. 본 논문에서 소개하는 웹 데이터베이스 응용 자동 생성기 WebGen은 웹 응용에 필요한 폼들과 이 폼들을 통해 이루어지는 질의에 대해 데이터베이스와 연동하여 처리하는 웹 스크립트들을 자동 생성하는 소프트웨어 도구다. WebGen은 웹 응용 개발자가 작성하는 구성파일(configuration file)에 정의된 선언적인 내용을 스크립트의 기본 원형인 내장된 템플릿(template)에 반영하여 5개의 웹 스크립트들(Search, Select, Edit, Information, Action)을 생성한다. Action 스크립트를 제외한 나머지 스크립트들은 사용자 인터페이스로 각각 해당되는 웹 폼을 생성한다. 따라서 웹 응용 작성을 위한 시간과 노력을 크게 줄여 웹 응용의 생산성을 향상시킨다. 상용 웹 응용 생성기들과 달리, WebGen은 독립적인 템플릿을 기반으로 하기 때문에 버전 관리가 용이하고 한 폼에 표현 가능한 정보도 관심의 대상인 엔티티 외에 이 엔티티와 직.간접적으로 연관된 모든 엔티티들을 포함한다.

The coat protein (CP) gene of Apple mosaic virus (ApMV), a member of the genus Ilarvirus, was selected for the design of virus-specific primers for amplification and molecular detection of the virus in cultivated apple. A combined assay of reverse transcription and polymerase chain reaction (RT-PCR) was performed with a single pair of ApMV-specific primers and crude nucleic acid extracts from virus-infected apple for rapid detection of the virus. The PCR product was verified by restriction mapping analysis and by sequence determination. The lowest concentration of template viral RNA required for detection was 100 fg. This indicates that the RT-PCR for detection of the virus is a 10$^3$times more sensitive, reproducible and time-saving method than the enzyme-linked immunosorbent assay. The specificity of the primers was verified using other unrelated viral RNAs. No PCR product was observed when Cucumber mosaic virus (Cucumovirus) or a crude extract of healthy apple was used as a template in RT-PCR with the same primers. The PCR product (669 bp) of the CP gene of the virus was cloned into the plasmid vector and result-ant recombinant (pAPCP1) was selected for molecule of apple transformation to breed virus-resistant transgenic apple plants as the next step. This method can be useful for early stage screening of in vitro plantlet and genetic resources of resistant cultivar of apple plants.

In accordance with the trend for cooperation of related company, BOM (Bill of Materials) has become an important factor in the manufacturing of production. BOM manages a various basic information of design, production, and process and so on. Especially, automobile industries are related to many company, they build a cooperative system from the communication of information. In this study, we have analyzed a BOM structure of a well-used automobile part industry and proposed a structure of engineering BOM, manufacturing BOM, process BOM for cooperative environment. A proposed various BOM structure are flexible in responding to the situation of structure alternations for automobile part. And also they include in environment factors. It is expected that these BOM structure will be used to basic template in automobile part industry which could be loaded with cooperative hub-system.

Three compounds, 5-(acetoxymethyl)-5-(hydroxymethyl)-3-tetradecyl-2,5-dihydro-2-furanone (3), 5-(acetoxymethyl)-5-(hydroxymethyl)-3,3-dihexyltetrahydro-2-furanone (4) and 5-(acetoxymethyl)-5-(hydroxymethyl)-3,3-dioctyltetrahydro-2-furanone (5), were designed and synthesized as surrogates of the ultrapotent DAG analogue, 5-(acetoxymethyl)-5-(hydroxymethyl) 3-[(Z)-tetradecylideneltetrahydro-2-furanone (1), a compound that showed high affinity for PKC-$\alpha$ ($K_1$=35 nM) in a competition binding assay with [$^3H$-20]phorbol-12,13-dibutyrate (PDBU). In an attempt to overcome the problem of generating geometrical E- and Z- isomers, as encountered with 1, the double bond was moved to an endocyclic location as in 3, or an additional alkyl chain was appended to C3 to give the corresponding 3,3-dialkyl saturated lactones (4 and 5). The lactone was constructed from glycidyl-4-methoxyphenyl ether in 5 steps. The target compounds showed reduced binding affinities for PKC-.alpha. with $K_{i}$ values of 192 nM (3), 4,829 nM (4), and 2,812 nM (5), respectively. These results indicate that constrained DAG analogues having a tetrahydro-2-furanone template are effectively discriminated by PKC-(X in terms of the direction of the long alkyl chain connected to the 3-position.n.

It is possible to design dental prosthesis in harmony with the patient's face and functional pathway using virtual patient created by integrating 3D diagnostic data such as intraoral scan, facial scan and jaw motion data. Also, esthetic teeth-gingiva relationship can be obtained, and post-surgical gingival outline can be predicted by using CAD software designed 3D surgical template during gingivectomy procedure. In this case report, 3D diagnostic data was collected from patients in need of esthetic anterior restoration, integrated on CAD software and applied to virtual articulator. Treatment outcome was simulated by creating virtual patient with dynamic occlusion. Esthetic anterior fixed restoration was fabricated by applying 3D surgical template designed on CAD software to gingivectomy procedure. To make sure that anterior guidance was formed in harmony with the patient's function pathway, occlusion was assessed following every step. The results were both functionally and esthetically satisfying.

This paper presents a well-designed templating system for CMS web Publication using XML/XSL technology. The primary motivation is the need of Web CMS to separate content from layout and logic. Our system provides GUI XSLT editor (x-editor) to create and modify XSLT stylesheet documents easily. These documents are used to add "layout" and "look and feel" information to XML document which contains content and functionality. The modified XML document is processed by XML-template engine to produce dynamic or static web sites.

In this paper, discrete-time cellular neural networks are designed in order to function as associative memories by using Hebbian learning rule and non-cloning template. The proposed method has a very simple structure to design and to learn. Weights are updated by the connection between the neuron and its neighborhood. In the simulation, the proposed method is applied to the classification of a traffic sign pattern.

워크플로우 시스템에서 워크플로우 프로세스에 관한 정의 정보는 일반적으로 데이터베이스에 저장되고 워크플로우 엔진은 이 데이터베이스로부터 필요한 정보를 인출하여 사용하게 된다. 엔진이 데이터를 검색하는 방법은 데이터베이스의 구조와 엔진의 구조에 따라서 매우 다양하다. 그 방법 중 하나로 워크플로우 엔진이 프로세스 정의가 저장된 데이터베이스를 직접 접근하여 원하는 정보를 가져올 수도 있으나 엔진과 데이터베이스 사이에 인터페이스를 두고서 간접적으로 접근하는 것은 많은 이점을 제공한다. 본 논문에서는 이러한 접근 방식의 이점 및 그 구현 기법에 관하여 ICU/COWS 라는 분산 워크플로우 시스템을 대상으로 논의한다.
