The Korean Demilitarized Zone (DMZ) has the great ecosystem as all the artificial activities in DMZ have been prohibited over half a century. The ecosystem should be conserved even after the reunification of Korea and hence the conservation plan should be established not after the reunification but before it. It requires a considerable budget to conserve DMZ, considering management of ecology resource, recovery, and research. The objective of this paper is to analyze a fund-raising measure for DMZ conservation, using economic incentives mechanism when multiple developers participate in the auction to get the right to develop North Korean regions, have private information about their sunk costs and pay a part of their profits for the fund. First, we analyze the real option model to decide the optimal investment time. Second, we construct the auction for bidders not to misrepresent their private information, based on Bayesian Nash equilibrium.

This study estimates the financial value of return on investment (ROI) of research funds. Four simulation estimations are employed to measure ROI finance value that considers the outputs, outcomes, impacts and total ROI from the allocation input received. Research outputs, outcomes, and impacts can be quantitatively measured based on improvements to existing systems. In terms of input, the Malaysian government has allocated MYR301,350,000 for fundamental research in the 2021 budget compared with 2019, up 9.5 percent from 2019. It brings up the question: To what extent does the input of research funds allocated by the government yield a good return in outputs, outcomes, and impacts to the academic community, society, and country? The result of total ROI shows around MYR7 return is generated by researchers for each Malaysian ringgit channeled by the funder. More specifically, for a research project, it is more difficult to produce impacts and outcomes compared to research outputs. The positive return is evidence that all the allocated funds are beneficial to the stakeholders. The government can apply this approach in calculating ROI for evaluation and fund allocation to universities. Furthermore, the positive financial value of research output, outcome, and impact automatically contribute to a positive innovation environment in Malaysia.

With the rapid development of oil and chemical industry in the late 20C, massive transportation of oil by oil tanker vessel has grown and it caused the big oil pollution accidents. When oil spill from the oil tanker, damages reach into the astronomical figures in economically and damages affect wide area and many people with break the balance of ecosystem. Recently in Korea, the oil pollution accidents has occurred frequently as growing of oil consumption and it caused large-scale damages to the victim. Oil pollution in Korean offshore takes not only korean fishermen from their life ground and break the ecosystem but it takes too much time and money to recover. To minimize oil pollution damages, it is necessary to make pre-caution effort as a ship owner and relevant government bodies should endeavor to prevent from more damages. But once oil pollution accidents occurs in territorial sea, compensation for victim fishermen is very important. But it is true that compensation is not paid to victim smoothly. So this study aims at the problems of oil pollution compensation to the Korean victim and find the best way to get reasonable compensation.

Venture capital invests the necessary capital and supports management and technology in promising small and medium-sized venture companies in the early stages of start-up with promising technology and excellent manpower. It plays a role as a key player in the venture ecosystem that realizes profits by collecting the investment through various means after growth. Venture capital's job is to recruit various investors(LPs) to invest in small and medium-sized venture companies with growth potential through the formation of venture investment funds, and to collect investment as companies grow, distribute and reinvest. The main tasks of venture capitalists, which play the most important role in venture investment, are finding promising companies, corporate analysis and evaluation, investment screening, follow-up management, and investment recovery. Venture capital's success indicators are fund formation and return on investment, and venture capitalists are rewarded with annual salary, performance-based incentive, and promotion with work performance such as investment, exit, and fund formation. Compared to the recent rapidly growing venture investment market, investment manpower is insufficient, and venture capital is making great efforts to foster manpower and establish infrastructure and systems for long-term service, but research has been conducted mainly from a quantitative perspective. Accordingly, this study aims to empirically analyzed the impact of investment experience, delegation of authority, job fit, and peer relationships on fund formation and return on investment according to the characteristics of the venture capital industry. The results of these empirical studies suggested that future venture capital needs a job environment and manpower operation strategy so that venture capitalists with high job fit and investment experience can work for a long time.

The purpose of this study was to provide guidelines for the remodeling understanding the needs of apartment housing residents. In order to achieve our goal, questionnaire surveys were used. We sampled the questionnaire surveys of the households in Seoul whose apartments had been more than ten years and recently remodeled. The materials collected by a questionnaire survey were analyzed by examining the frequency, percentage on the SPSS/PC+ Statistics package. The results of the questionnaire survey were as follows: (1) Residents tend to demand better environment than an economics benefits from remodeling. (2) Residents wanted to have organized the remodeling group that can help to solve the problems concerning profit and loss among residents. (3) Residents wanted to be supported by government, expand loans from monetary organizations, and have a reserve fund for the remodeling.

Two field test installations are discussed. In the first one a new ammonia sensor and an accurate ventilation rate sensor are combined. They are installed in the exhaust chimney in a ventilated pig house. The relative humidity and the room temperature are measured as well. In the second one, an in situ NH$_3$longrightarrowNO converter with subsequent NOx analyser is also being added for accurate ammonia measurement . In this way , the continuous measurement of the total NH$_3$emission can be obtained , the performance of the NH$_3$ sensor can be evaluated, and the ammonia reduction techniques can be tested. The outputs of measurement are fed into a data acquisition system then to a PC in the laboratory. There has been realised the first test installation with which research on the new ammonia sensor is carried out. The primary research results are presented.

This work was designed for the Green Fund Aid 2004 of Korea Forest Service. It won the prize and has been constructed. We can have an opportunity to play a leading role in improving partnership with participation of local communities, promoting environmental education, and enhancing the environmental quality by constructing biotops in urban areas where energy flow in the ecosystem is not balanced. This design includes 'citizen participation process' and 'local community partnership' that is expected to promote local community participation in the process of design. This work suggests that biotope construction with citizen involvement and community partnership plays an important role not only in design items but also in the revitalization of local community. This sort of design process could not be fully achieved without cooperation with stakeholders - environmental specialists, local authorities, relevant societies, schools, teachers, parents of students.

It is not the time when foodservice operations in Korea envy worldwide foodservice operations. For our foodservice operations to survive unlimited competition we do not wait for strong brand to be made, but make a worldwide brand through systematic tactics and strategy. To be a worldwide first-class foodservice operation we have to make first-class food products and a first-class brand accordingly. Brand has a power to lighten the future of a company and is in the limelight as a being to be attracted an attention from an invisible being. Brand is considered as a means to all the foodservice operations which invests enormous fund and time, and is appeared as a powerful weapon. It is not too much to say that 21st century is a marketing era centering on a brand. But this brand may be changed its property by various environment and changes. On the other hand it may be disappeared. Therefore more attention must be paid continuously about strategic actions to manage the brand. Now all companies can't promise to succeed without a powerful brand. The fact is that a worldwide brand to be made and developed is necessary. Also If not to do so it is very difficult to survive permanently.

A new simple relation for the estimation of modal correlation coefficients is presented. It is obtained from the decomposition of covariances of modal responses into background and resonant contributions, as it is commonly done for the variances. Thanks to appropriate assumptions, the modal correlation coefficients are estimated as weighted sums of two limit values, corresponding to the background and resonant responses respectively. The weighting coefficients are expressed as functions of the background-to-resonant ratios, which makes the proposed formulation convenient and easily accessible. The simplicity of the mathematical formulation facilitates the physical interpretation. It is for example proved that modal correlation coefficients can be non negligable even in case of well separated natural frequencies, which is sometimes unclear in the litterature. The new relation is mainly efficient in case of large finite element models. It is applied and validated on a finite element buffeting analysis of the Viaduct of Millau, the highest bridge deck ever built so far.
