Big Data environment is established by accumulating vast amounts of data as users continuously share and provide personal information in online environment. Accordingly, the more data is accumulated in online environment, the more data is accessible easily by third parties without users' permissions compared to the past. By utilizing strategies based on data-driven, firms recently make it possible to predict customers' preferences and consuming propensity relatively exactly. This Big Data environment, on the other hand, establishes 'Dataveillance' which means anybody can watch or control users' behaviors by using data itself which is stored online. Main objective of this study is to identify the relationship between Dataveillance and users' online privacy protection behaviors. To achieve it, we first investigate perceived online service efficiency; loss of control on privacy; offline surveillance; necessity of regulation influences on users' perceived threats which is generated by Dataveillance.

In this paper, we design and implement a parallel programming environment using graphicial user interface. Parallel program must be written according to the characters of various hardwares or programs. So it is difficult to write the parallel program. In this paper, we design and implement a parallel programming environment which solved this problem. The traditional parallel compiler provides the parallel information in the text environment. But this paper provides the parallel information using graphicial user interface so that the user may use it more easily. This parallel environment provide functions such as, data dependence analysis, CFG, HTF, and loop transformation.

Through the courses of industrialization, speedy growth and pluralism. The problems about the environment- friendly structures have become very important problem. Especially, it is getting highly appear to the expectation about the environment friendly buildings in Kangwon-do where has greacefully clean environment. The guide line for Kangwon-do can be arranged to the following through the varity analysis, outside enviroment, color, construction materials, outside design etc the guide line for Kangwon-do can be arranged as to the followings. It appears to be suitable to country houses in kangwon-do that is made of timber or red-bricks with green half circled roof and give a sense of warmth and soft. but the coastal area village is appeared wave style roof with orange color and surrounded by natural building stones or a line- plastered wall making complicated.

An issue of globalized and competitive business environment is a transformation of manufacturing strategy for rapidly product development. To copy with these trends, building up a market from various product is becoming conspicuous the core strategy of manufacture. Therefore, it is increasing of necessity for the environment of collaborative product development. As a part of corresponding for these demands, we propose the method that allows easy and rapid integration of legacy resources within the company and between departments. The proposed framework can easily construct a distributed environment for collaborative design between departments in the companies. It was implemented using CO/sup TM/ based on DOME (Distributed Object-based Modeling Environment) that is knowledge based engineering solution.

Re-consultation on Marine Environment Impact Assessment (MEIA) says that business operators are then licensed back from the disposition authorities undergoing a consultation process to change business plans. Marine Environment Management Act has provisions(Article 94) with respect to a case where the scale of business, the period of business, reflects the basic plan, including a plan to change a variety of reasons. But increasingly diverse types of businesses and projects which are the subject of MEIA, As it appears that the vulnerability issues and the problem of the re-consultation. In this study conducted an analysis of the literature review and comment on the re-consultation report four years. In addition, it presents a check to the problem through concrete examples related to the re-consultation and proposes improvement measures.

I introduce the Flexible Dam Operation (FDO) and some of sediment control techniques In dams which are implemented as trials to avoid or reduce environmental impact of dams on the downstream reaches. The FDO is a dam management method to improve river environment in the downstream reaches by means of the flushing flow, the maintenance flow and so on utilizing a vacant portion of capacity for flood control without interrupting prime flood control function during the rainy/typhoon season. It Is suggested by the guideline of the FDO that EDO should be implemented regularly after the trial for about three years. The basic conception of the FDO is described here. The example of excavation of deposited sediments in check dams and placement of sand ana gravel immediately downstream of the dams and the example of coordinated sediment flushing are described as some of sediment control techniques in dams. Now they are at the stage of experiment and trial. Therefore, it is important to increase examples and establish the technical methodology and the environmental evaluation method for them.

In this study, we compared and analyzed the Arduino-based IoT coding environment, which is most frequently used in OSHW, and the microbit-based IoT coding environment developed and spread in the UK. The results show that a microbit-based educational environment can offer a variety of benefits. Although the basic problems are defined and compared, many differences occur. Microbit-based environment has less overhead than Arduino-based environment, which is effective for IoT coding education.

Fatigue crack growth behaviour of Ti-6A-4V alloy is investigated in air and salt solution environment at room temperature and $200^{\circ}C$. Fatigue crack growth rate is blown to be fast for the formation of corrosive product in hot salt environment. For the effect on corrosion fatigue crack growth behaviour of region II. fatigue crack growth rate in atmosphere had a little gap to both case, $200^{\circ}C$ and room temperature. However, it showed very fast tendency in salt corrosive atmosphere, and it was remarkably accelerated in $200^{\circ}C$ temperature salt environment. When $\Delta$K was approximately 30MPa(equation omitted), fatigue crack growth rate had a little difference between at room temperature and at $200^{\circ}C$ high temperature, however in case of salt corrosive environment the room temperature was 3.5 times Inter and $200^{\circ}C$ high temperature for 16 times than air environment respectively.

It is known that slab thermal storage which uses concrete slab as thermal material is effective in the load leveling and using the nighttime electric power. The temperature distribution is not constant in plenum in thermal storage time by beams, ducts such as several factor. It is considered that this fact will effect on efficiency of thermal storage and indoor thermal environment. The purpose of this paper is to examine the thermal environment inside plenum. A macro model was made for the analysis of indoor thermal environment as the first step. The flow rate distribution and temperature distribution of object room model was examined by use of basic equations such as airflow by the pressure difference between unit cells, heat flow by air and heat transfer.

In order to keep the school's environment safe and clean, it needs to have a regular control system. There are limits to the student's abilities on keeping the school safe and clean, therefore cleaning professionals and specialized companies are needed as well. In case of financial program, principals or chief administrations are in charge of school building's environmental management. And it might cause poor efficiency and imbalance of distributing works on business in their charge and there are limits to keep the school's environment. This paper prepares alternatives of effective school building managements to solve these problems.
