TDR(Tear Down & Redesign)means that renounce the past resolutely, from a white paper condition, let's change directions. That is, let's redesign from the basic of the establishment of the construction process. Through the switchover the conception, innovate totally the whole existing processes. TDR is the best core innovation activity. The ultimate aim of the TDR activity induces the employees to do more productive business and obtain excellent results in the future by solving the problems, which are the nonproductive business in the business process on the objective view, the business that customers don't recognize the value, the same old practice of business, and the unsettled business from the restriction of resources. By organizing the related to workers of those business, they can solve the problems for 3-4months by full time working This paper inquires what are the obstruction factors on the process of executing TDR activity. Through the search of the reformation plan for the improvement of immersion degree, it presents some methods to be successful business.

Government-sponsored Research Institutes (GRIs) have made a great contribution to the development of Korea's Science and Technology (S&T). However, recently, GRIs are facing the challenge of many problems, for instance, absence of reasonable strategies, insufficient resources, and so on. Therefore, many GRIs are required for solving these problems by enhancing their strategic management capabilities. For this purpose, this paper suggests a Strategic Management Audit Model for Korean GRIs. The concept of Strategic Management Audit Model has not been widely adopted in Korean GRIs. In this paper, we suggest GRI-specific Strategic Management Model and apply it to Korea Basic Science Institute (KBSI), which is under the Korea Research Council of Fundamental Science and Technology (KRCF). Based on our strategic management audit, we propose several potential strategies for Korean Basic Research Institutes (KBSI). Our model and its implications will also be helpful for other Korean GRIs.

The number of industrial Internet of Things (IoT) users is increasing rapidly. Lightweight block ciphers have started to be used to protect the privacy of users. Hardware-oriented security design should fully consider the use of fewer hardware devices when the function is fully realized. Thus, this paper designs a lightweight block cipher IIoTBC for industrial IoT security. IIoTBC system structure is variable and flexibly adapts to nodes with different security requirements. This paper proposes a 4×4 S-box that achieves a good balance between area overhead and cryptographic properties. In addition, this paper proposes a preprocessing method for 4×4 S-box logic gate expressions, which makes it easier to obtain better area, running time, and power data in ASIC implementation. Applying it to 14 classic lightweight block cipher S-boxes, the results show that is feasible. A series of performance tests and security evaluations were performed on the IIoTBC. As shown by experiments and data comparisons, IIoTBC is compact and secure in industrial IoT sensor nodes. Finally, IIoTBC has been implemented on a temperature state acquisition platform to simulate encrypted transmission of temperature in an industrial environment.

BACKGROUND/OBJECTIVES: Petasites japonicus Maxim (P. japonicus) has been used as an edible and medicinal plant and contains many bioactive compounds. The purpose of this study is to investigate the effect of P. japonicus on osteogenesis. MATERIALS/METHODS: The leaves and stems of P. japonicus were separated and extracted with hot water or ethanol, respectively. The total phenolic compound and total polyphenol contents of each extract were measured, and alkaline phosphatase (ALP) activity of each extract was evaluated to determine their effect on bone metabolism. To investigate the effect on osteoblast differentiation of the aqueous extract of P. japonicus leaves (AL), which produced the highest ALP activity among the tested extracts, collagen content was measured using the Sirius Red staining method, mineralization using the Alizarin Red S staining method, and osteocalcin production through enzyme-linked immunosorbent assay analysis. Also, real-time reverse transcription polymerase chain reaction was performed to investigate the mRNA expression levels of Runt-related transcriptional factor 2 (Runx2) and Osterix. RESULTS: Among the 4 P. japonicus extracts, AL had the highest values in all of the following measures: total phenolic compounds, total polyphenols, and ALP activity, which is a major biomarker of osteoblast differentiation. The AL-treated MC3T3-E1 cells showed significant increases in induced osteoblast differentiation, collagen synthesis, mineralization, and osteocalcin production. In addition, mRNA expressions of Runx2 and Osterix, transcription factors that regulate osteoblast differentiation, were significantly increased. CONCLUSIONS: These results suggest that AL can regulate osteoblasts differentiation, at least in part through Runx2 and Osterix. Therefore, it is highly likely that P. japonicus will be useful as an alternate therapeutic for the prevention and treatment of osteoporosis.

Recently many Korean large-sized construction companies as well as specialty contractors have been expanding their business in the overseas market to mitigate impacts from long-term stagnation in the domestic market. Such as a result, it has been arisen as a major issue that contractors effectively manage the delays which have been commonly faced with in international mega-projects. Therefore it can be said that the ability of the delays management leads a success of project. This paper presents a review of literature for delay analysis methods such as time impact analysis(TIA) and raises practical problems to rationally substantiate the duration of extension of time(EoT) in international mega projects which have wide scope of works as well as complicated and detailed contract baseline programs by taking theoretical approaches. We suggest the two improvement concepts to substantiate the EoT claims which are effectively applicable to practical projects. The first is to sort out dominant delays among numerous delays in advance of applying a delay analysis. The second is to set up the delay sections with the advanced concept for analysing delays' effects by TIA. This study performed a case study on an actual international mega-project. to confirm the effectiveness of improvement concepts that this practical approach is applicable for the assessment of EoT. In conclusion, this paper supposes to provide practitioner in charge for an EoT claim with an advanced substantiation methodogy when they not only analyse the construction delays by using TIA, but also negotiate with stakeholders about with the assessment of EoT.

The objective of this paper is to think about what structural reforms of the Korean government S&T development management system might be. Korean society is currently experiencing a drastic socio-economic transformation. The results of this transformation should be reflected on the determining process of the directions and breadths of structural reforms of government S&T development management system. Because the government system design will be based on the premises of socio-economic conditions under which administrative activities perform and also this socio-economic changes can influence on changes of the premises of government management system design. Moreover, S&T development management system is a subsystem of government system so that the directions of structural reform of those subsystems should be considered in the broad framework changes in the development management system of the government. For the last forty years, the Korean government S&T development management system has been based on the premises including transformation from an agrarian society to an industrial society, authoritarianism and centrally controlled institutions, and exteremely small portions of private investments for science and thechonology R & D of the total. Recently, however, the premises of Korean government S&T development management system have rapidly changed. the characteristics of these changes are including tranformation from an industrial society to a knowledge and information intensive society, globalization, localization, and relatively large portion of private investments for science and technology R & C of the total. The basis of government reforms in Korea was the realization of the performances and values through the enhancement of national competitive capacity, attainment of lean government, decentralization and autonomy. However, the Korean government has attached a symbolic value of strategic organizations representing strong policy intentions of government for the science and technology based development. Most problems associated with the Korean government S&T development management system have grown worse during 1990s. Many people perceive that considerable part of this problem was generated because the government could not properly adapt itself to new administrative environment and the paradigm shift in its role. First of all, the Korean government S&T development management system as a whole failed to develop an integrated vision under which processes in formulating science and thechology development goals and developing consistent government plans concerning science and technology development are guided. Second, most of the local governments have little organizational capacity and manpowers to handle localized activities to promote science and technology in their regions. Third, the measure to coordinate and set priorities to invest resources for the development of science and technology was not effective. Fourth, the Most has been losing its reputation as the symbol of ideological commitment of the top policy maker to promote science and technology. Various ideas to reform government S&T development management system have been suggested recently. Most frequently cited ideas are as follow : (ⅰ)strengthen the functions of MoST by supplementing the strong incentive and regulatory measures; (ⅱ)create a new Ministry of Education, Science & Technology and Research by merging the Ministry of Education and the MoST; (ⅲ)create a new Ministry of Science & Technology and Industry ; and(ⅳ)create a National Science and Technology Policy Council under the chairmanship of the President. Four alternatives suggested have been widely discussed among the interested parties and they each have merits as well as weaknesses. The first alternative could be seen as an alternative which cannot resolve current conflicts among various ministries concerning priority setting and resource allocation. However, this alternatives can be seen as a way of showing the top policymaker's strong intention to emphasize science and technology based development. Second alternative is giving a strategic to emphasize on the training and supplying qualified manpower to meet knowledge and information intensive future society. This alternative is considered to be consistent with the new administrative paradigm emphasizing lean government and decentralization. However, opponents are worrying about the linkages and cooperative research between university and industry could be weakening. The third alternative has been adopted mostly in nations which have strong basic science research but weak industrial innovation traditions. Main weakness of this alternative for Korea is that Korean science and technology development system has no strong basic science and technology research traditions. The fourth alternative is consistent with new administrative paradigms and government reform bases. However, opponents to this alternative are worried that the intensive development of science and technology because of Korea's low potential research capabilities in science and technology development. Considerning the present Korean socio-economic situation which demands highly qualified human resources and development strategies which emphasizes the accumulations of knowledge-based stocks, I would like to suggest the route of creating a new Ministry of Education, Science & Technology and Research by intergrating education administration functions and science & technology development function into one ministry.

"Great things in business are never done by one person; they're done by a team of people." By Steve Jobs, 2003. As define by Linda Naiam - Creativity is the act of turning new and imaginative ideas into reality. Creativity involves two processes: thinking, then producing. Innovation is the production or implementation of an idea. If you have ideas, but don't act on them, you are imaginative but not creative. So in order to maintain the pace with the changing business scenario and coping with the competition Innovation and Creativity is considered a mandatory tool for a business to exist and grow in market. Whether a company is Employee centric or Business centric Innovation and creativity has to have its space in order to keep a business ahead of others in the Market. Also it's not just the competition which has led to the Innovation and Creativity in Business practices it's also the demanding chunk of consumers and customers who are aware and prefer maximum choices before making a final deal. Another reason as to why there is a change in business practices is the globalization of businesses where you need to rope in the Innovative ideas to launch and sustain in new market. There had been tremendous shift in business practices but to give a room to innovative ideas and implement that creativity need ample to space and vision along with an attitude where in you can resist for getting an immediate results from innovative business practices. Corporate Creativity is characterized by the ability to perceive the world in new ways, to find hidden patterns, to make connections between seemingly unrelated phenomena, and to generate solutions. Generating fresh solutions to problems, and the ability to create new products, processes or services for a changing market, are part of the intellectual capital that give a company its competitive edge. Creativity is a crucial part of the innovation equation. The innovation and creativity is not limited to any area of business, it can start from your waiting lounge to your board room meeting depending upon how the things are perceived and implemented for the betterment of people and business. The purpose of this research is to understand the latest creative business approaches and practices that organizations are following to be different from their competitors. Also this shift from generic business practices to the Innovative and Creative approach seems to take the business into new world. This approaches means starting from the bottom of the Pyramid and finally touching the pinnacles in Innovation and creativity. The paper will discuss on the various areas of business where in innovative approaches can be roped in and sets new bench mark altogether in the business arena.

Vitis amurensis Rupreche, a sort of grape, grows naturally in Asian countries. It is known for important biological effects such as antioxidation, anti-inflammation, neuroprotection, and angiogenesis inhibition. Although its root is used as a traditional folk medicine in Korea, the root's biological activities are poorly studied. In the present study, the effects of V. amurensis root methanol extract (VARM) and its solvent fractions on adipocyte differentiation and adipogenesis in 3T3-L1 preadipocytes were investigated. The VARM significantly suppressed adipocyte differentiation, lipid accumulation, and the triglyceride (TG) content of 3T3-L1 preadipocytes in a dose-dependent manner, without cytotoxicity. To identify active molecules, the VARM was fractionated with a series of organic solvents including dichloromethane ($CH_2Cl_2$), ethyl acetate (EtOAc), and n-butanol (n-BuOH). All the fractions also showed inhibition of lipid accumulation in the 3T3-L1 preadipocytes. The $CH_2Cl_2$ fraction showed the most powerful anti-obesity effect through the modulation of cytidine-cytidine-adenosine-adenosinethymidine (CCAAT)/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), $C/EBP{\beta}$, peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) gene and protein expression. Oleanolic acid was one of the main active compounds involved in the anti-obesity activity of the V. amurensis root. These results provide important new insight into the potential potent anti-adipogenic effect of the V. amurensis root and illustrate that one of the main compounds involved in this effect is oleanolic acid.

It is well known that compensation satisfaction of employees is closely related to work attitude, job commitment, and employees'intentions to stay on the job. These known facts can also be applied to the professionals engaged in science & technology as well. Many studies have concluded that the Korea's losing competitiveness in the area of science & technology was mainly attributed to the distorted compensation system. In this vein, this paper identifies the potential determinants that affect the compensation satisfaction of S&T professionals, and to empirically examines the determinants influences on job commitment and intention to stay. This was done by acquiring data from S&T professionals currently being employed in firms, universities, and institutions. Consequently, for professionals engaged in science & technology, the compensation satisfaction was demonstrated to be largely influenced by job accomplishment, monetary compensation, and social compensation in order. In conclusion, to improve compensation system for S&T professionals, firstly, it is recommended to enhance job accomplishment by endowing more discretionary authority to conduct research. Secondly, the relatively lower-valued labor forces in S&T area will necessitate more economic support and compensation. Finally, the social compensation should be strengthened by not only ameliorating social status, but also improving labor liquidity and job security.
