최근 스마트폰과 같은 다양한 애플리케이션을 사용할 수 있는 모바일폰의 유행에 힘입어 모바일 애플리케이션 수요가 폭발적으로 증가하고 있고, 이에 따라 모바일 애플리케이션에서에 품질의 중요성도 점차 커지고 있다. 하지만 모바일 애플리케이션은 다양한 플랫폼이나 모바일폰의 제약사항에 따라 플랫폼이나 디바이스 장치 간의 호환성이 떨어지는 특성을 가짐으로써, 다른 플랫폼에서 애플리케이션을 재사용하기 위해서 해당 플랫폼이나 모바일폰의 제약사항에 따라 다시 개발해야하는 제약을 가진다. 따라서, 본 논문에서는 모바일 애플리케이션을 타 플랫폼에서 재사용하기 위해, 이식할 때 발생할 수 있는 문제를 확인하고 그에 따른 기존 모바일 애플리케이션에 이식의 편이를 확인할 수 있는 이식성 품질 평가 기법을 제안한다. 이에 따라 제안한 이식성의 편이를 나타내는 이식성 점수를 확인함으로써 모바일 애플리케이션이 타 플랫폼에 이식될 때 발생할 수 있는 문제점을 확인하고 이에 따른 재개발 가능 여부와 노력 정도를 확인할 수 있는 근거가 될 수 있을 것으로 기대된다. 또한 이를 모바일 애플리케이션의 설계부터 고려한다면 다양한 모바일 플랫폼에 좀 더 쉽게 이식할 수 있는 품질 좋은 모바일 애플리케이션을 개발할 수 있는 방법이 될 수 있을 것으로 기대된다.

In this paper, we implemented a safety navigation mobile application that converged AtoN information and location-based services. When application user uses the smartphone's GPS sensor to transmit the user's vessel location data to the data server, the user receives information of which its providing range is considered, such as stored AtoN data, neighboring vessels information, danger area, and weather information in the server. Providing information is sorted based on the smartphone's direction and inclination and it will be also delivered via wireless network (5G, LTE, 3G, WiFi). Additionally the application is available to implement other functions such as information provision through voice and text alarming service when the user's vessel is either approaching or entering the danger area, and an expanded information provision service that is available in shadow area linking with data-storing methods; other linkable data such as weather and other neighboring vessels will be applied based on the lasted-saved data perceived from the non-shadow area.

This study was carried out to use efficiently forest resources through the survey of analysis of consciousness for the application of other use following quarrying. The application types of other use following quarrying were 366 people (49.5%) for forest recreation, 164 people (22.2%) for facility application, 117 people (15.8%) for vacation facility, and 93 people (12.6%) for tree planting types. According to the test of independence between facility utility types and gender, male preferred the leisure facility type, but female preferred the forest recreation type. The tree planting type was not related to the gender, but male preferred facility application types. Also, female preferred a static use type such as recreation and walking, while male preferred a dynamic use type such as the leisure and facility application types. According to the test of independence between facility application and occupation types students and company employees preferred the leisure facility type, while school faculty and staff, self employees, and housewives preferred the forest recreation type. Public servants preferred tree planting and facility application types. The sojourn time was the overnight and 6-8 hours in the leisure facility type, within 4 hours in the forest recreation and tree planting types, and 6-8 hours in the facility application types. Other use plans of the quarry site following quarrying will be needed to establish quarry facility application models with consideration for visitor's preferences.

Smart application is developed in this paper by using an android-based platform to automatically determine the human emergency state (Lifesaver) by using different technology sensors of the mobile. In practice, this Lifesaver has many applications, and it can be easily combined with other applications as well to determine the emergency of humans. For example, if an old human falls due to some medical reasons, then this application is automatically determining the human state and then calls a person from this emergency contact list. Moreover, if the car accidentally crashes due to an accident, then the Lifesaver application is also helping to call a person who is on the emergency contact list to save human life. Therefore, the main objective of this project is to develop an application that can save human life. As a result, the proposed Lifesaver application is utilized to assist the person to get immediate attention in case of absence of help in four different situations. To develop the Lifesaver system, the GPS is also integrated to get the exact location of a human in case of emergency. Moreover, the emergency list of friends and authorities is also maintained to develop this application. To test and evaluate the Lifesaver system, the 50 different human data are collected with different age groups in the range of (40-70) and the performance of the Lifesaver application is also evaluated and compared with other state-of-the-art applications. On average, the Lifesaver system is achieved 95.5% detection accuracy and the value of 91.5 based on emergency index metric, which is outperformed compared to other applications in this domain.

Fisheries Act is to provide for scope of application as follows : (1) Except as provided otherwise, the provisions of this act shall not apply to any waters other than a public one. (2) If waters other than a public one are connected to and integrated with the latter, the provisions of the act shall apply to the former. This paper aims to analyze these Fisheries act.

The differential response of soybean cultivars with or without sulfur (S) application was observed under fold conditions. Plant biomass decreased by sulfur deficiency but the reduction was less in Bragg variety about 26 % relative to the control than other ones over 45%, probably due to less reduction in loaves and pods. The photosynthetic rate of Bragg cultivar was also unaffected by the absence of sulfur application while it depressed in other lines. Soybean cultivars were compared in terms of storage protein, protein quality and biomass production by application of sulfur nutrition. The storage protein concentration tended to decrease without sulfur application in all the cultivars, however the differential response of protein quality only by 11S/7S ratio to sulfur nutrition status was observed: For instance, Bragg cultivar had higher biomass and protein production but protein quality decreased at sulfur deficiency. On the other hand, biomass and protein production in other cultivars remained louver at sulfur deficiency but protein quality differed genetically in spite of sulfur nutrition status. These results suggest that the response of soybean to sulfur nutrition is controlled by genotypic difference and sulfur supply status.

Recently days, High Accelerated Life Test of electrical and electronic parts is increasing its importance. This study set the hypothesis to develop the method that was analysis and application of HALT for the automotive electrical and electronic parts, it used Arrhenius's Model and Eyring's Model, and ESS theory. Validity of application is proved by other test data. Especially, this study emphasis on utility of acceleration to temperature, humidity, voltage, mechanical stress and other stress. In this study set the pattem of practical application. Therefore, this study emphasis on the application of the HALT and the use of other parameter by acceleration reliability test data. The result of this study is as follows. 1) There is relationship between molar weight and material constant. 2) Characteristic of material is operating acceleration factor as well as parts failure factors. Of course, according to the characteristic of material, activation energy is often more important than molar weight. But it will be defined by more testing and improvements in practical application.

In this paper, we propose a hybrid multi.system-on-chip (H-MSoC) architecture that provides a high-flexibility system in a rapid development time. The H-MSoC approach provides a flexible system-on-chip (SoC) architecture that is easy to configure for physical- and application-layer development. The physical- and application-layer aspects are dynamically designed and modified; hence, it is important to consider a design methodology that supports rapid SoC development. Physical layer development refers to intellectual property cores or other modular hardware (HW) development, while application layer development refers to user interface or application software (SW) development. H-MSoC is built from multi-SoC architectures in which each SoC is localized and specified based on its development focus, either physical or application (hybrid). Physical HW development SoC is referred to as physical-SoC (Phy-SoC) and application SW development SoC is referred to as application-SoC (App-SoC). Phy-SoC and App-SoC are connected to each other via Ethernet. Ethernet was chosen because of its flexibility, high speed, and easy configuration. For prototyping, we used a LEON3 SoC as the Phy-SoC and a ZYNQ-7000 SoC as the App-SoC. The proposed design was proven in real-time tests and achieved good performance.
