This paper formalizes a special type of social networking knowledge, which is called "workflow performer-role affiliation networking knowledge." A workflow model specifies execution sequences of the associated activities and their affiliated relationships with roles, performers, invoked-applications, and relevant data. In Particular, these affiliated relationships exhibit a stream of organizational work-sharing knowledge and utilize business process intelligence to explore resources allotting and planning knowledge concealed in the corresponding workflow model. In this paper, we particularly focus on the performer-role affiliation relationships and their implications as organizational and business process intelligence in workflow-driven organizations. We elaborate a series of theoretical formalisms and practical implementation for modeling, discovering, and visualizing workflow performer-role affiliation networking knowledge, and practical details as workflow performer-role affiliation knowledge representation, discovery, and visualization techniques. These theoretical concepts and practical algorithms are based upon information control net methodology for formally describing workflow models, and the affiliated knowledge eventually represents the various degrees of involvements and participations between a group of performers and a group of roles in a corresponding workflow model. Finally, we summarily describe the implications of the proposed affiliation networking knowledge as business process intelligence, and how worthwhile it is in discovering and visualizing the knowledge in workflow-driven organizations and enterprises that produce massively parallel interactions and large-scaled operational data collections through deploying and enacting massively parallel and large-scale workflow models.

The fuel cell system is environment-friendly and energy efficient system. Especially, the fuel cell cogeneration systems providing heat and electricity to buildings have been developed and applied to a lot of sites in the world to cope with the global warming and $CO_2$ emission problem. This paper presents the result of study on the economic evaluation with super-micro fuel cell (SMFC) cogeneration system by varying the floor area ($132m^2{\sim}331m^2$) of the house, whose system capacity ranges from 0.10 kWe to 0.50 kWe. The electricity demand, heat demand, saved energy cost, and the simple pay-back period have been simulated for the various capacities of fuel cell cogeneration system. As a result, this study suggests the fuel cell system's capacity decision strategy for a given house area. Contrary to conventional design assumptions, the smaller capacity fuel cell cogeneration system is appropriate for the house of large floor area to defense the progressive electricity tax, and the larger capacity fuel cell cogeneration system is appropriate for the house of small floor area to sell the electricity.

The Korean Government has recently prepared the comprehensive five-year basic plan (2006-2010) to deal with low fertility and population ageing. The basic plan aims at recovering the fertility rate to the appropriate level and improving the social and economic systems in preparation for the aged society. The main objective of this study was to examine the effects of fertility policies on childbirth by birth order. The data came from 1,729 adults who gave birth to babies in 2007 and 991 adults as the control group. The serial logistic regression analyses revealed that establishing the health and nutrition system for maternity and children, and expanding of tax and social insurance benefit were effective policy measures to increase childbirths of first children, while the policy measures establishing the health and nutrition system for maternity and children, supporting for daycare and pre-school education, and work-life balance were effective to childbirths of second or third children in 2007. However, the policies of supporting for costs of test-tube baby and expanding childcare infra didn't have any significant influences on childbirths in 2007. The implications of study results were discussed.

This paper studies a series of capital market promotion policies Korea pursued over a 30-year period during its development era (1960s - 1980s). The purpose of this paper is twofold. The first purpose is to understand the policy approaches Korea took, and the second is to extract lessons that can benefit policymakers in the developing world, where capital market promotion is an important policy goal. There are two key features of Korea's capital market promotion policies. First, the government was actively involved, sometimes indirectly by giving tax incentives to encourage IPOs. However, in other times, it was directly involved by giving IPO orders and threatening those that did not comply. No stock exchange in a developed country has ever experienced such government involvement. Combined with rapid economic growth, this interventionist approached allowed the Korean stock market to experience phenomenal growth over a short period of time. Second, the capital market promotion policies had multiple objectives. One was to mobilize domestic capital for economic development. Another was to lower firms' debt-to-equity ratios. Most interestingly, however, the Korean government wanted to popularize stock ownership, thereby allowing ordinary Koreans to share in the fruits of economic growth.

In commercial combustion systems, heavy oil is one of main hydrocarbon fuel because of its economical efficiency. Regarding heavy oil combustion, due to increasing concerns over environmental pollutants such as carbon monoxide, unburned hydrocarbon and nitrogen oxides, development of low pollutant emission methods has become an imminent issue for practical application to numerous combustion devices. Also a great amount of effort has been tried to developed effective methods for practical using of biomass. It is also an important issue to reduce carbon tax. In this paper, an experimental study has been conducted to evaluate the effect of biomass reburning on NOx formation in a heavy oil flamed combustion furnace. Experiments were performed in flames stabilized by a multi-staged burner, which was mounted at the front of the furnace. Experimental tests were conducted using air-carried rice husk powder and LNG as the reburn fuel and heavy oil as the main fuel. The paper reports data on flue gas emissions and temperature distribution in the furnace for several kinds of experimental conditions. NOx concentration in the exhaust has decreased considerably due to effect of reburning. The maximum NOx reduction rate was 62% when the rice husk was used by reburn fuel, however it was 59% when the LNG was used by reburn fuel. The result shows the positive possibility of biomass reburning system for optimal NOx reduction.

The main aim of the study is to test a house pricing model by combining hedonic and asset-based pricing models. An understanding of the relationship between house pricing and its return (the rental income) helps to establish houses as a significant asset class. The model tested the relationship between house pricing (dependent variable) and the house attributes (independent variables) derived from Freeman's framework of housing attributes. This study uses a large data-set of 1,899 sample of new, high-end houses purchased between 2016 and 2019 collected from the national capital region of India (Delhi-NCR). The algorithm was built in R-Script, and stepwise multiple linear regression was used to analyze the model. The analysis of the model proves that the three significant variables, namely, carpet area, pay-off, and annual maintenance charges explain the price function. Further, the model is statistically fit. The major contribution of the study is to understand the key factors and their influence on the house pricing. The model will be helpful in risk assessment in the housing investment and enhance the chances of investment. Policy-makers can use information about the underlying valuation drivers of the house prices to stabilize the market and also in framing the tax policies.

우리나라의 부동산가격공시제도는 건설교통부의 공시지가 및 주택가격공시제도, 행정자치부의 시가표준액, 국세청의 기준시가로 나뉘어져 있다. 토지와 건물이 시장에서 일체로 거래되고 있음에도 불구하고, 담당기관들은 토지와 건물을 분리하여 평가 과세하고 있다. 한국의 부동산가격공시제도의 근본문제는 여기에서 시작된다. 2005년 주택가격공시제도가 도입되었으나 근본적인 문제점은 여전히 해결되지 않은 채 남아 있다. 근본적인 해결책을 찾기 위하여, 국가는 모든 토지와 건물의 가격을 일괄평가하여 공시하는 방향으로 현행 부동산가격공시제도를 개선해나가야 한다.
