One of the most difficult tasks in pavement management information systems is establishing the links between performance measures of a structure and the design and construction inputs. In-situ pavement performance can be considered a response variable to many project input variables, such as design, construction, and traffic loading effects. If we are to fully understand the component of pavement performance and specify the inputs through design and construction specifications to achieve that performance we must develop quantitative relationship between input and response variables through a scientific, fully integrated Pavement Performance Analysis System (PPAS). Hence, the objective of this study is to design a database model required for developing an effective database template that will allow analysis of pavement performance measures based on design and construction information linked by location. In order to select the most appropriate database model, a conceptual database model (Entity Relationship Model) and dimensional model, which is believed to be the most effective modeling technique for data warehouse project, are designed and compared. It is believed that other state highway agencies could adopt the proposed design strategy for implementing a PPAS at the discretion of the state highway agencies.

A design pattern is a general reusable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Moreover, the name of pattern itself also can be a kind of common language among developers and patterns can be easily imported to various applications demanding similar requirements. In this paper, we present models of CBTC onboard system which follows ERTMS/ETCS specifications and present patterns applied to our system.

A geometric kernel is the library of core mathematical functions that defines and stores 3D shapes in response to users'commands. We developed a light geometric kernel suitable to develop CAD/CAM application systems. The kernel contains geometric objects, such as points, curves and surfaces and a minimal set of functions for each type but does not contain lots of modeling and handling functions that are useful to create and maintain complex shapes from an idea sketch. The kernel was developed on MS-Windows NT using C++ with STL(Standard Template Library) but it is compatible with UNIX environments. This paper describes the structure of the kernel including several components: base, math, point sequence curve, geometry, translators. The base kernel gives portability to applications and the math kernel contains basic arithmetic and their classes, such as vector and matrix. The geometry kernel contains points, parametric curves, and parametric surfaces. A neutral fie format and programming and document styles are also presented in this paper.

Glucagon-like peptide 2 receptor, a GPCR, binds with the glucagon-like peptide, GLP-2 and regulates various metabolic functions in the gastrointestinal tract. It plays an important role in the nutrient homeostasis related to nutrient assimilation by regulating mucosal epithelium. GLP-2 receptor affects the cellular response to external injury, by controlling the intestinal crypt cell proliferation. As they are therapeutically attractive towards diseases related with the gastrointestinal tract, it becomes essential to analyse their structural features to study the pathophysiology of the diseases. As the three dimensional structure of the protein is not available, in this study, we have performed the homology modelling of the receptor based on single- and multiple template modeling. The models were subjected to model validation and a reliable model based on the validation statistics was identified. The predicted model could be useful in studying the structural features of GLP-2 receptor and their role in various diseases related to them.

In this paper, we propose a new method of reconstructing the hand models for individuals, which include the link structure models, the homologous skin surface models and the homologous tetrahedral mesh models in a reference posture. As for the link structure model, the local coordinate system related to each link consists of the joint rotation center and the axes of joint rotation, which can be estimated based on the trajectories of optimal markers on the relative skin surface region of the subject obtained from the motion capture system. The skin surface model is defined as a three-dimensional triangular mesh, obtained by deforming a template mesh so as to fit the landmark vertices to the relative marker positions obtained motion capture system. In this process, anatomical dimensions for the subject, manually measured by a caliper, are also used as the deformation constraints.

인터넷 상에서의 다양한 멀티미디어 응용 및 정보 서비스의 요구가 급증하게 되고, 이에 따른 효율적인 운영 및 서비스에 대한 표준 기술의 개발 또한 활발히 진행되게 되었다. 이에 1998년 W3C(World Wide Web Consortium)에서 웹 기반 동기화 된 멀티미디어 통합 언어인 SMIL이 제안되었다. 선언적 마크업 언어인 XML(eXtended Markup Language)에 기반을 둔 SMIL은 웹 상에서의 멀티미디어 프리젠테이션을 위한 다양한 기능들을 제공하지만, SMIL 또한 HTML(HyperText Language)과 같은 태그 기반 마크업 언어이므로 각 태그의 사용법을 숙지하여 텍스트 편집기를 이용한 비효율적인 저작에 치중되어 있었다. 이에 SMIL 응용업무에서의 효율적 활용을 위한 SMIL 전용 저작도구의 필요성이 대두되었고, 국내외에서의 활발한 연구 개발이 진행되고 있다. 본 논문에서는 UML(Unified Modeling Language) 표기법에 기반 한 객체지향 모델링 툴을 사용하여 체계적인 소프트웨어 설계에 따른 SMIL 저작도구를 구현하였다. 템플릿 기능의 지원으로 효율적이고 편리한 SMIL 컨텐츠 생성을 위하여 인턴넷 망(network)의 대역폭에 따른 저작이 가능하도록 구현되었으며, 미리 보기 기능을 활용한 멀티미디어 데이터의 직관적이 운영을 지원하도록 구현하였다.

Protein phosphatase manganese dependent 1D (PPM1D) is one of the Ser/Thr protein phosphatases belongs to the PP2C family. They play an important role in cancer tumorigenesis of various tumors including neuroblastoma, pancreatic adenocarcinoma, medulloblastoma, breast cancer, prostate cancer and ovarian cancer. Even though PPM1D is involved in the pathophysiology of various tumors, the three dimensional protein structure is still unknown. Hence in the present study, homology modelling of PPM1D was performed. 20 different models were modelled using single- and multiple-template based homology modelling and validated using different techniques. Best models were selected based on the validation. Three models were selected and found to have similar structures. The predicted models may be useful as a tool in studying the pathophysiological role of PPM1D.

The gasdermins are a family of recently identified pore-forming effector proteins that cause membrane permeabilization and pyroptosis, a lytic pro-inflammatory type of cell death. A role in the regulation of cell proliferation and/or differentiation is suggested by the differentiation status-specific expression of gasdermin proteins in epithelial tissues. One of the GSDM protein is Gasdermin A (GSDMA), which decreased in stomach and esophageal cancers, suggesting a tumor suppressor role. GSDMA receptor antagonists have been researched as potential treatments for inflammatory diseases and baldness. GSDMA's significance in a wide range of disorders makes it an important therapeutic target. As a result, homology modelling of the GSDMA receptor was undertaken in the current study using the crystal structures of Mus musculus (GSDMA3), Human gasdermin D (GSDMD), and Murine gasdermin D (murine GSDMD). The best model was chosen based on the validation results after 20 models were developed utilising single template-based approaches. The generated structures can be used for further binding site and docking studies in the future.

Currently, generative artificial intelligence is a hot topic around the world. Generative artificial intelligence creates various images, art, video clips, advertisements, etc. The problem is that it is very difficult to verify the internal work of artificial intelligence. As a requirements engineer, I attempt to create a toon image by applying linguistic mechanisms to the current issue. This is combined with the UML object model through the semantic role analysis technique of linguists Chomsky and Fillmore. Then, the derived properties are linked to the toon creation template. This is to ensure productivity based on reusability rather than creativity in toon engineering. In the future, we plan to increase toon image productivity by incorporating software development processes and reusability.

본 논문은 한옥 설계 지원 시스템을 개발함에 있어서 부재의 수를 획기적으로 줄이면서 한옥을 설계할 수 있는 효과적인 부재 표현방식을 제안하고자 한다. 한옥은 규모, 지붕의 모양, 공포의 유무 등에 따라 다양하게 분류할 수 있으며 결구방식 및 연결부재에 따라 부재의 수가 매우 다양하다. 이러한 다양한 부재를 모두 설계하게 되면 설계 시에 부재의 사용과 취급이 어려워진다. 이러한 문제를 해결하기 위해서 전남 표준한옥올 중심으로 한옥의 목구조 방식을 체계적으로 분석하고 특성이 비슷한 부재들을 모아서 하나의 템플릿으로 설계하여 다양한 형태의 유사부재들을 속성 값에 따라 자유롭게 생성할 수 있도록 객체지향 방식의 표현기법을 사용한다. 제안된 방식은 객체지향 방식의 부재를 표현함에 있어서 연결 부재간의 상관관계를 부재와 부재간의 관련 파라미터들 사이의 결합규칙을 적용함으로써 설계의 오류를 최소화 하도록 지원할 수 있다.
