In this paper, I analyze the difficulties of web service development education for non-IT majors through the Q&A of students posted in the k-mooc lecture, and propose methods to improve them. Through Q&A analysis, it was confirmed that non-majors mainly had difficulties in using unfamiliar tools, cost of cloud service, setting up server environment, and writing code while taking web service development courses. To solve this problem, I propose a method to reduce the server cost problem and the complexity of the server environment by using BaaS(Backend as a Service), which is one of the cloud service models. It also shows that it is possible to reduce the length of code that needs to be written at once by using the React library to modularize long code into smaller units. Finally, I propose an improvement plan that even non-IT majors can easily learn by implementing a web application that works by using the design output obtained by using Figma.

Personal information is defined information related to users' privacy data. It can be verified information through social security number, image, and means relating to individual can verify. Such personal information is in accordance with the privacy act in law for the collection and usage in enterprises and institutions. However, it can be induced privacy problem when it is exposed information without attention. This user's inadvertent disclosure of personal information has occurred due to social engineering and intelligent cyber-crime occurred in order to solve these problems. A variety of protection solutions for personal information have been developed. Web privacy filtering firewall and solutions related with server have been developed among developed many solutions, web privacy filtering and firewall solutions is proposed in this paper.

As developers and testers today we all suffer from increasing project complexity, the risks of late defect discovery, repetitive manual processes, and the risk of release delays. In this paper, we introduce an effective framework for automated testing to help solve such problems. Those that are new to testing do not need to delve into complex automation tools or test scripts. This framework helps automate the distribution, execution and results analysis of test cases. It also aids communication among the various stakeholders, using tables for representing tests and for reporting the results of automatically checking those tests. This paper describes the practices and benefits of using the proposed framework.

In this paper, a web-based automatic transcription component is designed and implemented for mechanical conversion of revised Korean-to-Romanization notation rule. Specially. we proposes system architecture and algorithms that transcript Korean to Roman automatically after transliterate Korean to phonetic symbol applying phonological principles. The components operate under the web server's script mechanism. and the dictionary for exceptional usage is designed as an accessorial function supported either operating at web server internally or externally. The overall system architecture is presented by UML. specification and pseudo code. The proposed architecture can be implemented in encapsulated service by object oriented component and that can be easily adapted and modified on the internet environment and this system may have many advantages to improve efficiency, library reuse. extensibility at software development.

Algorithm visualization is useful for program testing, debugging and evaluating, as well as visual aids in education. When teaching algorithms and data structures, showing exact behaviors by graphics or animation is more suitable than just explaining them. Current systems for algorithm animation are limited to a couple of specific applications and need a special environment. In the proposed system, programmer writes source program in C and animator embeds visualization scripts in the appropriate location of the program. Then user can get an animation code in form of SVG and see a graphical representation on the web browser. Generated SVG animation code is platform independent and can also interact with other XML applications or HTML.

Java 플랫폼 기반의 스크립트 언어인 Groovy는 GroovyMarkup을 이용하여 컴포넌트 및 콘테이너, 객체가 중첩된 구조로 이루어져 있는 GUI 프로그램을 간결하고 쉽게 작성할 수 있다. 본 논문에서는 GroovyMarkup을 확장해 고성능의 GUI 프로그램을 구현할 수 있는 SWT Builder를 구현하였다. 본 논문에서 구현한 SWT Builder의 성능 및 기능 평가를 위해 기존에 구현된 SWT Builder, Swing Builder와 비교하여 실험하였다. 테스트 한 결과, 구현한 SWT Builder는 GUI 구성 시간에 있어 기존 SWT Builder보다 1.4배 더 빠른 속도를 가진다. 또한 기능 부분에서는 Factory 클래스 소스 코드의 자동 생성, 클래스 기능 문서 자동 생성 등 으로 프로그래머에게 더 많은 편의성을 제공한다.

Schedule management of construction work is important in order to complete construction projects within a given period of time. As activities increase and relations become more complex, schedule management software becomes increasingly necessary. To address this, attempts are being made to incorporate web-based ICT (information and communications technology) in construction project management. This research proposed a method to manage construction schedules via web pages using Flash. The interactive and graphic property of Flash enables a field manager to manage schedules easily and efficiently. A prototype was implemented using Flash and Action Script, and it was applied to a sample network in a web page.

WebShell is a web script file created by a hacker to remotely commands to a web server. The hacker can bypass the security system using the web shell, access the system, control the system such as file modification, copying and deletion, install malicious code in the web source code, attack the user's PC, And so on. There are many types of WebShell attack, but we study about attacks on PHP and JSP based web server which are used as representative ones. And we propose the method of web page management, method of development, and several other methods. By using these countermeasures, it is possible to effectively prevent damage caused by WebShell attacks.

2018 년 평창 동계올림픽부터 우리나라 사람들이 컬링이라는 종목에 큰 관심을 갖기 시작하였다. 하지만 이 종목을 직접 체험하거나 경기를 보기 위해서는 빙판이 있어야 하는 특수성과 비싼 장비, 찾아보기 힘든 경기장 등 여러 열악한 조건들 때문에 결국 올림픽 시즌에만 반짝 관심을 가졌다가 시들어버렸다. 이를 해결하기 위해서 우리는 Unity 라는 게임 엔진을 사용하여 사람들이 쉽게 접할 수 있는 컬링 게임을 제작하였다. 실제 컬링을 게임으로 만들기 위해 컬링에 필요한 도구들을 이미지로 제작하여 Unity 내부에서 저장 후 오브젝트에 입력하였고 물리 법칙을 구현하기 위해 Unity 상에서 방향, 세기, 속도, 충돌들을 프로그래밍하였으며 대한컬링연맹에 나와있는 컬링 경기 규칙서를 활용하여 게임에 적용하였다. 또한 컬링의 진행이 현실적인 운동과 비슷하게 하기 위하여 스크립트 안의 충돌 및 마찰 관련 계수를 조절하였고 이를 이용하여 반복한 결과값들을 수치화 하여 그래프로 작성해보았다. 추가적으로 컬링 게임의 점수판과 카메라 시점 등을 통해서 게임 사용자가 게임 진행에 있어서 도움이 되는 부분을 구현하였고 현실성을 위하여 Arduino 를 이용한 게임 패드를 제작하여 직접 게임하는 듯한 느낌을 들도록 하였다. 최종적으로 게임을 이용하여 컬링에 대한 이해도가 증가하고 사람들이 컬링이라는 비인기 종목에 한 걸음 더 접근할 수 있게 되고, 스포츠발전에 조금이나마 기여할 수 있게 될 것이다.

정지궤도 위성을 제외한 대부분의 저궤도 위성 및 심우주 관측용 위성은 임무를 수행하면서 하루동안에도 제한된 시간동안만 지상국과의 통신이 가능하다. 따라서 위성 운영에 고수준의 자율적 제어기능이 요구된다. OBCP(On-Board Control Procedures)는 별도로 개발된 언어로 작성한 작은 용량의 스크립트 프로그램을 통해 위성을 제어하는 기능을 제공한다. 이러한 방법을 통해 지상관제 시에 위성의 임무수행동안 수행되어야 하는 다양하고 복잡한 운영 시퀀스를 용이하게 준비하고 업로드할 수 있다. OBCP는 위성비행소프트웨어와는 분리된 별도의 서브시스템으로 수행되기 때문에 새로운 위성운영 프로시져의 생성을 위해 위성비행소프트웨어의 수정, 재검증, 코드업로드 등의 절차가 요구되지 않으며 지상에서 개발 및 검증시험을 완벽하게 수행할 수 있다. 본 논문에서는 기존의 저궤도 관측위성에서 사용되었던 위성의 자율적 제어 시퀀스 기능과 OBCP의 기능을 비교하여 설명하고, 실제 Herschel and Plank 위성에 활용된 예를 통해 OBCP의 개념 및 설계 방안에 대하여 소개한다.
