The death from suffocation due to the gas from various disaster is frequent very and it occurs. Specially only from the company which treats the gas and only the enterprise which maintains the gas the many greeting accident occurs. Also accidents could occur when working around the toxic gas without one's noticing Therefore a development of the portable gas ditectoror is very essential. Specially with development of design and the new product of the electric chemical sensor might help reducing the many accidents. From the side which protects a worker's life, it isn't just simple equipment but also it must be connected directly to life saving is very important. Therefore, the key technical contents of development must be focused on sensor which is simple and easy to carry and able to detect varieties of toxic gas. So, this study is about the product design which is simple and easy to carry and to use.

In order to calculate the Crop Water Stress Index (CWSI), it is necessary to collect weather data (air temperature, humidity, wind speed and solar radiation) and canopy temperature. However, it is not always available to have necessary data sets for CWSI calculation. Therefore, this study was aimed to develop an easy and simple CWSI equation (CWSI_EE) using only two data, air and canopy temperatures. Infrared sensors and weather sensors were installed on apple and peach trees and nearby a study area and every ten-minute data were collected from June to October in 2018 and 2019, respectively. A relationship between air-canopy temperature difference and CWSI was statistically analyzed and used to develop CWSI_EE using the three dimensional Gaussian model. The performance of CWSI_EE against original CWSI showed R² and NSE to 0.780 and 0.710 for apple trees and R² and NSE to 0.884 and 0.866 for peach trees. This study found that the level of crop water stress could be easily calculated using CWSI_EE with only air and canopy temperature data.

In this paper, we propose a Model Driven Development using UML(Unified Modeling Language) in an efficient Combat System Software development methods. UML is managed by the OMG (Object Management Group) as a Unified Modeling Language. Recently, In developing the software for the system, development time is contrary to a short, while it must meet a number of requirements of our customers. If you develop a non-efficient software early, the structure of the software become more complex in proportion to the number of requirements. As a result, a serious problem in the system, such as an increase in defective products due to the lowering of the reliability and communication problems between the developer has occurred. To overcome those problems, the aim of this paper is to develop a reusable high efficient Combat System Software by applying Model-Centric Development (Not Code-Centric Development). If Combat System Software development method using the UML proposed in this paper is used, easy communication among developers can help reduce the serious errors in systems. Also, it has the advantage that the future needs of software maintenance/repair become easy by using high readability object Model.

In this paper, we try to explore basic factors that defines easy-to-learn programming language and easy-to-learn development environments for novice students who have not been exposed to computer programming language education. For these purpose, we investigate and analyze computer programming languages that are widely used in industrial environments, and present the summary and analyzed results. From the experimental results, most novice programmers understand computer programming languages in terms of procedural programming languages rather than in terms of functional programming languages or object oriented programming languages. Furthermore, we have found that, for effective education of basic level programming languages, factors of development environments are much more important than factors of programming paradigms that the computer programming languages are based on.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

지리정보시스템은 다양한 학문 분야와 여러 전문 기술을 필요로 하는 복합적인 소프트웨어 시스템이므로 일반적인 시스템에 비하여 개발 과정의 복잡도가 높고, 개발된 시스템의 사용자 인터페이스나 수행 연산을 이후에 변경하기가 쉽지 않다. 그러므로 이미 개발된 지리정보시스템이 존재하여도 상이한 응용 분야에 사용될 목적으로 다른 지리정보시스템을 구축하고자 할 경우 이의 대부분을 재개발하여야 하는 경우가 많다. 즉, 이미 개발된 지리정보시스템에 대한 이후의 재사용이 용이하지 않다. 따라서 개발된 기존 지리정보시스템의 기능을 재사용할 수 있도록 하여 이를 바탕으로 다양한 응용 분야의 지리정보시스템을 용이하게 구축하고자 하는 연구의 필요성이 제기된다. 본 논문은 클라이언트 중심 웹 지리정보시스템의 구조를 기반으로 하여, 응용 웹 지리정보시스템의 구축을 용이하게 할 목적으로 웹 지리정보시스템 프레임워크를 설계하고 구현한다. 프레임워크는 클래스(class), 객체, 모듈 등과 같이 재사용 가능한 단위로 이루어진 소프트웨어 라이브러리를 의미한다. 제안하는 웹 지리정보시스템 프레임워크는 기본적인 웹 지리정보시스템의 기능과 수행 구조를 제공하여 웹 지리정보시스템 개발자로 하여금 응용 분야에 필요한 연산과 사용자 인터페이스만을 추가하여 다양한 응용 분야의 요구 조건을 만족하는 응용 웹 지리정보시스템을 용이하게 구축할 수 있도록 한다. 이는 또한 웹 브라우저가 지원하는 기존의 개발 환경을 통하여 이루어지므로 기존의 웹 어플리케이션 개발 도구를 그대로 사용할 수 있다.

The aim of the study is to develop a jean jacket and pants of easy-to-move for schoolgirls of 11 years old. The research was carried out as follows; 1. Using a manufacturer's pattern, a jean jacket and pants were made. 2. Based on the survey of 108 schoolgirls, interviews with 4 designers of children's wear, and wearing test, three trial garments were developed. -Certain areas such as knee, elbow, and hip should be altered to have better extensibility. -The weight of the garment would be better to be reduced. 3. Three trial garments were developed using following techniques, which were found in fashion magazines for kids very often. -Alter the location and the shape of the seam line so that the areas mentioned above can adjust the movement of the body better. -Match stretchable material at the areas which require better extensibility. -Use various trimmings to make the garment more size adaptable and easy-to-move. 4. These garments were tested by 26 schoolgirls, and they answered the questionnaires focused on the design preference and easy-to-move. 5. From the results of the wearing test of three trial garments, more effective techniques were selected. Using these techniques, prototype garment was developed. The prototype garment was approved by the wearing test of 26 schoolgirls.
