In this paper, we have proposed on the Matching Table of 'Type of If Business - Class of IT Techniques' to train If manpower as an educational-industrial cooperation. The Type of If Business(TITB) are classified according to ${\triangle}$IT Services, ${\triangle}$IT Devices, and ${\triangle}$Software & Computer related Services which are guided by KAIT(Korea Association of Information & Telecommunication). The Class of IT Techniques(CITT) are brought from IITA(Institute for Information Technology Advancement). We have suggested on the element techniques from the Class of If Techniques(CITT) according to the Type of IT Business(TITB) and proposed an educational-industrial cooperation program to line up 'Type of IT Business(TITB) - Class of IT Techniques(CITT) - University(Department/Major)'. The deduction process of the core education program is presented to show the educational-industrial cooperation between company(Type of IT Business : Digital Contents Development Service) and university(Major of Multimedia & Contents) in the Busan area. The Matching Table of 'Type of IT Business(TITB) - Class of IT Techniques(CITT)' varies as the way of classification according to IT Business and IT Techniques. The research on the real and exact Matching Table of 'Type of IT Business(TITB) - Class of IT Techniques(CITT)' is necessary for educational-industrial cooperation by the trends of techniques and the changes of IT market share.

The market trends of automatic meter reading associated with smart water meters were investigated. Also, recent developments and field applications of key technology for automatic meter reading associated with smart water meters were analyzed. Smart water meters have been manufactured mostly in United States and Europe and have been expanded their business to Asia. Integrated water management system combining with the additional functions such as real-time consumption metering, cost notification, water conservation, leak detection, water quality monitoring, and flow control have been operated in automatic meter reading. Both water quality and quantity data measured from smart water meters and sensors were transferred to data concentration units through neighborhood area network, and then were transferred to integrated server through wide area network. The data transfer methods were determined by comprehensively considering urban scale, density of smart water meters, power supply and network topologies. Common data collection methods such as fixed network to data concentation units, vehicles drive by, people walk by, and drone fly by have been applied. The automatic meter reading associated with smart water meters are spread throughout the world, and both water and energy savings result in saving the money and reducing the greenhouse gases emission.

Since the 1990s, the notion of governance has been introduced as an alternative way of understanding the new trend of public administration. Then, it was followed by the emergence of the concept, e-governance (electronic governance) with the development of information and communication technologies. E-governance means an approach to understanding how to manage state affairs. It emphasizes the notion of governance where various actors (government-market-civil society, etc.) adjust and cooperate through mutual collaborative network, not a unilateral decision-making form of government, in order to solve common problems. It also carries the notion of 'electronic' in the sense that it operates on the basis of utilizing information and communication technology (ICT). This study systematically attempts to analyze research trends and methodologies of e-governance in major Korean journals and proceedings in the field of public administration and policy studies over the last 15 years. Some of the findings are worth noting: first, e-governance studies in Korea are in large measure concentrated on the government-centered perspective. Also, past studies tend to focus on problem-solving by suggesting policy alternatives. Past studies, thus, seem to pay relatively less attention to explanation of the phenomena through rigorous analysis. Under the circumstances, this review is expected to shed light on some of conceptual or methodological issues related e-governance studies, thus, to provide significant implications for future research of e-governance.

In the light of real situation of Korean timber resources, it is no wonder that Korean economy depends on a lot of imported timber, however, we only need to draw attention how have they kept the balance of payment in the field of forest products trade for the last few decades, until the second oil crisis in 1979. Afterwards, the gap between imports and exports of forest products in terms of value has been widened so far, on account of various reasons inside and outside. However, according to national economic policy to drive more active exportation, new policy and strategy to expend world market of forest products urgently expectable in order to shorten the gap between imports and exports of forest products in the future. On the other hand, the current timber importation policy should be reconsidered, not only to support optimum domestic timber price level so as to compensate timber producers' cost but also to make suitable economic environment to induce new investments in the field of private forestry sector.

Since 2010, Korea's overseas construction orders have seen dramatic fluctuations. I propose causes and remedies for the industry as a whole. Orders have recorded an annual average of $63.8 billion dollars from 2011 to 2014, reaching its highest at $71.6 billion dollars(2010) which marked the peak of Korea's overseas construction. However, due to a decline in international oil prices, starting in the last half of 2014, Korea's overseas construction orders have followed suit recording $46.1 billion dollar in 2014, $28.2 billion dollars in 2016, and $29.0 billion dollars in 2017. Facing uncertainty in Korea's overseas construction market, caused by continued slow growth of the global economy, Korean EPC contractors are at a critical point in regards to their award-winning capabilities. Together with declining oil prices, the challenges have never been bigger. To mitigate the challenges, I would suggest policy direction as a way to grow and develop the overseas construction industry. Proper counterplans are needed to foster Korea's overseas construction industry. Forecasting total order amount for overseas construction projects is essencial. Analyzing contract award & tender structure and its changing trends in both overseas and world construction markets should also be included. Korea has great potential and global competitiveness. These measures will serve to enhance Korea's overall export strategy in uncertain overseas markets and global economy.

Since unloaded Q-value of a high-temperature superconductor(HTS) filter is very high, a bandpass filter(BPF) and a lowpass filter(LPF) with an increase of pole numbers can be fabricated without an increase of an insertion loss(IL) ; recently a 70-pole BPF is developed in USA. They have an abrupt skirt property and an excellent attenuation level for out-of band. Moreover, they can be miniaturized when lumped element resonators or the slow-wave characteristic are used. Technology of fabricating a HTS epitaxial film as well as a film of a 4 inch area also makes the planar type filter with a various structure and an enhanced power handling capability possible. Recently, the HTS filter subsystems composed of a planar-type HTS filters, a GaAs-based LNA and a mini-cryocooler are developed. The extended receiver front- end subsystems for mobile radio communications decrease the noise-figure level of the communication system and the frequency interference interacted adjacent bands, and increase the efficiency of frequency and the capacity of communication system. In this paper, theory for developing the HTS filter, its kinds, its design rules, its characteristics are reviewed. The feature of the research and market trends related to the HTS filter systems for the receiver front-end subsystem of mobile base station are surveyed.

According to UPOV (International Union for Protection of New Varieties of Plants), mushroom spawn market have to be opened by the year 2009. Number of commercial strains distributed by the year 2005 were 179 of 24 species of edible and medicinal mushrooms. Only nine strains of oyster mushrooms were registered as protected variety, which is not compatible with those recorded in other advanced countries. Meaning of spawn in broad sense contains commercial strains. Development of commercial strains faces two main problems in Korea : One is the complicated genetic patterns and sexuality of mushroom species, and the other is expensive experimental equipments and fruiting body growing houses. Resolution of these problems leads to development of mushroom strains. This could be achieved as follows; genetic resources collection and assessment, molecular characterization of useful genetic characters, development of new commercial strains by hybridization using typical genetic resources, strengthening of breeding research using "Mushroom Breeding Group", management of spawn research company by consortium, foundation of mushroom general industry, promotion of consumption, and upgrade of competition ability for other countries. These points are under discussion.

Hollow-fiber membranes, is one of the new technologies that is growing rapidly in the past few decades. In addition, separation membranes using polymer materials, have attracted attentions in various fields including gas separation, fuel cells, water treatment, wastewater treatment, and organic separation. Nanofiltration (NF) membranes having the separation characteristics in the intermediate range between ultrafiltration and reverse osmosis (RO) membranes for liquid separation, with relatively low investment cost and operating pressure lower than that of RO membranes, have high permeance and rejection performance of multivalent ions as well as organic compounds of molecular weight between $200{\sim}1000gmol^{-1}$. In this paper, we would like to review the research trends on the various structure control and characterization of NF hollow fiber membranes with respect to materials and the methods of preparation (phase inversion method and interfacial polymerization method). Currently, most of NF membranes have been manufactured by plate and frame types or spiral wound types. But hollow fiber types have delayed in commercial products, because of the weak strength when to produce on the basis of the existing materials, therefore the development of new materials or improvement of existing materials will be needed. If improving manufacturing technology is available, hollow fiber types will replace spiral wound types and gradually show a higher market share.
