With the increasing diversification and complexity of urban regeneration projects in Korea, the role of intermediary support organizations has become increasingly emphasized. Among them, Urban Regeneration Centers (URCs) serve as pivotal institutions that connect local governments, residents, and experts, thereby playing a central role in determining the effectiveness of urban regeneration policies. However, many URCs are constrained by short-term operational structures, unstable staffing systems, and a lack of continuity in project implementation, which collectively hinder their organizational sustainability. This study aims to explore a sustainable operational model from a mid- to long-term perspective by conducting an empirical analysis of the Cheonan Urban Regeneration Center. Utilizing qualitative methodologies including in-depth interviews, a Delphi survey, and comparative case analysis, the study comprehensively examines key factors such as organizational structure, human resource management, financial stability, and potential for functional expansion. The findings indicate that functional specialization, establishment of a stable staffing system, integrated organizational restructuring, and legal-institutional reinforcement through transformation into a public foundation are essential conditions for sustainable operation. Based on these results, the study provides policy implications to support the institutionalization and strategic advancement of Urban Regeneration Centers nationwide.

This paper has suggested the national living safety crisis as the new field of the national crisis and emergency management and proposed its operating strategy. Because we, Korean people, have faced the various new types of crises increasingly, for example, harmful food and drug, dangerous traffic accidents, and lots of risks in the school. So, as the developed countries established the safety mechanisms for their people, we have to prevent and prepare for the living safety crisis and accidents. This article divided the national living safety crises into four types(type 1, 2, 3, 4) according to the two criteria; both the responsible subject for the safety(individual, society) and the scope of occurrence and damage(narrow scope, middle range & wide scope). This study proposed the realization of the safety in the usual life as a vision of the newly suggested national living safety sector and the advanced safety management system in the usual life as a strategic goal for achieving the vision. For our safe living conditions, the following directions are needed; improving the legal institution and the administrative system, training the specialist, institutionalizing the safety budget, establishing the networks among the related organizations, distributing the safety management manual, and forming the safety culture and consciousness, etc.

본 연구는 세무상 정보인 이월결손금(NOL)의 크기와 법인세율의 인하가 경영자의 이익조정에 미친 영향을 분석하였다. 먼저 법인세율 인하시 기업의 이익조정 행위를 관찰한 결과, 이익기업과 손실기업이 다른 의사결정을 한 결과를 보였다. 전체 기업에서는 음(-)의 이익을 조정하였으나, 이익기업에서는 양(+)의 이익조정을 하였다. 이러한 결과는 전체기업은 조세비용최소화를 위한 의사결정을 하였으나 이익기업은 비조세비용의 감소를 위한 의사결정을 한 결과이다. 둘째로 이월결손금의 크기에 따른 경영자의 이익조정 행위를 관찰한 결과, 이월결손금이 있는 이익기업의 경우에는 양(+)의 이익조정을 하여 이월결손금이 경영자의 이익조정에 중요한 영향을 미치는 변수가 될 수 있음을 확인하였다. 이월결손금의 경우에 전체기업을 대상으로 한 경우에는 음(-)의 이익조정을 하여 개별기업의 특성에 따라 다른 의사결정을 하고 있음을 알 수 있었다. 셋째로 법인세율 인하와 이월결손금을 동시에 고려할 경우, 법인세율 인하를 이용하고자 하면 음(-)의 이익조정을 할 것이고 이월결손금을 이용하고자 하면 양(+)의 이익조정을 할 것인데, 실증결과 전체기업의 경우 이월결손금에 더 큰 비중을 두어 의사결정을 하여 양(+)의 이익조정을 한데 비하여 이익기업의 경우 전체기업과 달리 법인세율 인하에 반응하여 음(-)의 이익조정을 하였다. 본 연구는 법인세율 인하에 따라 경영자가 어떻게 이익조정을 할 것인지에 대한 일관된 결론이 없는 상태에서 실증분석의 축척된 결과를 제시하고, 손실기업이 포함된 경우에 손실기업의 특성상 전체 기업과 다른 이익조정을 할 가능성이 있음을 제시하였다. 또한 이월결손금의 유무나 이월결손금의 공제여부가 아닌 이월결손금 자료를 직접 수집하여 이월결손금의 크기에 따른 경영자의 이익조정을 분석하였다는 점에서도 공헌점이 있다. 그리고 본 연구는 선행연구에서 시도하지 않았던 법인세율 인하와 이월결손금을 동시에 고려한 경영자의 이익조정을 분석하였다는 의의가 있다.

2009 Tax reform includes a reduction of corporate tax rate and an extension of the period during which you can deduct the net operating losses. Tax reform has a direct impact on the taxable income and tax paid. However, Because taxable income is calculated by adjusting accounting profit, Executives have an incentive to tax minimization by adjusting the accounting profits. But, Firms may not even exist depending on the nature of the company’s profit that aims to minimize the tax adjustment. This study was a departure from the question whether or not managers to achieve tax minimization strategies in accordance with the tax revision. This study analyzes the effects of tax information (net operating losses (“NOL” hereafter) and reduction of corporate tax rate) on earning management. This study first shows the regression results that deduction of corporate tax rate has significant effect on earnings management while profit firms has a positive relation and all company have negative relation between these two variables, which implies that (i) the managers of profit firms have a decision for lowering nontax expenses (ii) the managers of overall firms follow the strategy to minimize tax burden. Because loss firms don’t use net profit as a measure of executives’ evaluation, the executives of profit firms compared with the executive of loss firms are more sensitive to the non-tax costs. Previous studies was no consistent conclusions. In other words, when the corporate tax rate is lowered, we could not make a definite conclusion due to the difference in the results of the empirical test. It is shown that the difference in the results of the empirical test is due to the fact that the characteristics of the individual firms. Furthermore, it is shown that NOL amount has significant effect on earnings management. Profit firms has a positive relation and all company have negative relation between these two variables, which implies that NOL amount has an important role to decide the tax strategy against the variation of regulation circumstances. It shows that Profit firms that have more NOL do earning management a lot more because of effect which reduces tax paid. But, loss firms that have bigger amount of NOL want to occur more loss. Because Possibility that gains occur will be high later although loss more occur in this year. It is also shown that the difference in the results of the empirical test is due to the fact that the characteristics of the individual firms. Finally, it is shown that in case of considering both the tax rate and NOL amount, the firms which have bigger amount of NOL make an earnings management in upper way, however, which have lower amount of NOL make an earnings management in under way. Profit firms select tax strategy that use the reduction of tax rate and all firms select tax strategy that use NOL. This result implies between tax variables, firms choose the strategy differently following their own purposes. It is important that this study has tried to analyze an earning adjustment considering both the reduction of corporate tax rate and NOL at the very frist. Previous studies don’t analyze simultaneously tax rate and NOL. It is also shown that the difference in the results of the empirical test is due to the fact that the characteristics of the individual firms. This study was present repetitive results of empirical analysis whether or not Executives adjust the accounting profits when the corporate tax rate was lower. These repetitive results give a confidence about the relation of reduction of tax rate and earning management. On the other hand, this study had a contribution about NOL studies. We were collected directly NOL data and was extended the target year of the study. Previous studies have estimated NOL instead of collection data by hand. These contributions in spite of this study have limitations. Measure of earnings adjustment measure used as the dependent variable in this study, the problem of measurement error has been mentioned in several studies. There was a limit, however, because of the firm's earnings are made in a variety of ways, from the steps of the present study not only can be used.

최근 청소년범죄의 흉포화와 저연령화에 대응하기 위해 법무부에서는 2022년에 촉법소년 나이 하한을 주 내용으로 하는 법무부 소년범죄대책을 발표하는 등 다양한정책적 변화를 모색하고 있다. 그러나 그 내용을 살펴보면 소년범죄문제 해결을 위한 미시적인 대책에 그치고 소년사법정책의 전반적인 시스템의 변화를 통한 근본적인 관리 방안에 대한 논의는 다소 부족한 것으로 보인다. 한국의 경우 소년 사범의더 효과적인 관리를 위해서 소년사법 관리에 관한 통합시스템의 구축을 통해 보다근본적으로 소년범죄에 대응하는 방안을 모색해볼 필요가 있다. 이를 위해 1998년 영국 정부에서 소년범죄자 효과적인 관리 방안으로 도입된YJS(Youth Justice Service)가 소년범죄와 관련된 각종 지표에서 긍정적인 결과를 보여 주목할 필요가 있다. 소년범죄 문제가 날로 심각해지고 있는 현시점에서 영국의운영체계를 살펴보고 한국에의 도입 가능성과 구체적인 방안을 살펴볼 필요성이 있다. 물론 정부 조직의 운영체계나 사회·문화적 차이로 인하여 제도 자체를 그대로도입하는 데에는 한계가 있겠지만, 한국적 상황에 맞는 시스템의 변화나 구체적 프로그램의 운영형태 중 도입 가능한 부분을 세밀히 살펴보고 적용 필요성을 살펴보는과정이 꼭 필요하다고 본다. 이 논문은 YJS의 탄생배경과 구체적인 운영방식을 살펴보고 한국적 상황에 적용 가능성을 모색하는 것이 목적이다.

In response to the increasing brutality and lower age of onset in juvenile crime, the Ministry of Justice announced the “Juvenile Crime Countermeasures” in 2022, with the primary focus on lowering the age threshold for juveniles, among other policy changes. However, a closer examination of the content reveals that these measures remain largely micro-level responses to juvenile crime, falling short of a broader discussion on fundamental management approaches through systemic reform of the juvenile justice policy as a whole. In the case of Korea, there is a pressing need to explore more fundamental approaches to addressing juvenile crime through the establishment of an integrated management system for juvenile justice. Youth Justice Service (YJS), introduced by the British government in 1988 as an effective approach to managing juvenile offenders, has demonstrated positive outcomes. At a time when juvenile crime is becoming an increasingly serious issue, it is necessary to examine the operational framework of the United Kingdom and explore the feasibility and specific measures for its introduction in Korea. While there are inherent limitations to adopting the system due to differences in governmental structures and socio-cultural contexts, it is essential to carefully identify which aspects of the system’s design or specific program operations are adaptable to the Korean context. The purpose of this paper is to examine the background of the YJS’s establishment and its specific operational mechanisms, and to explore the possibilities of applying them to the Korean context.

Optimal feeding strategies in bioreactor operation of Scutellaria baicalensis G. plant cell culture were investigated to maximize the production of flavone glycosides by using a structured kinetic model which can predict culture growth and flavone glycosides synthesis in a rigorous, quantitative manner. For the production of baicalin and wogonin-7-0-GA, the strategies for glucose feeding into Scutellaria baicalensis G. plant cell culture were proposed based on the model, which are a periodic fed-batch operation with maintenance of cell viability and of specific production rate respectively, and a perfusion operation with maintenance of specific production rate for baicalin and wogonin-7-0-GA. Simulation results showed that the highest volumetric concentration of flavone glycosides was obtained in a periodic fed-batch operation with maintenance of cell viability among all the suggested strategies. In the periodic fed-batch operations, the higher volumetric production of flavone glycosides was achieved compared with that in the perfusion operation. It can be concluded that a periodic fed-batch operation with maintenance of cell viability would be the optimal and practical operating strategy of Scutellaris baicalensis G. plant cell culture for the production of flavone glycosides.

Increasingly in both South Korea and the United Kingdom, the public themselves feel a need to prevent from crimes because of declining police resources. Police is finding it difficult to meet the demands of the public in terms of crime and fear of crime prevention and the provision of a visible uniformed presence. To better respond to these needs private security firms have filled the gap in large private spaces such as shopping malls, hospital, residential complexes. Particularly, security officers at shopping mall also have a vital role in crime prevention and dealing with anti-social behaviours. This study presents the comparative study of the contribution of private security in private spaces in the two countries. This study will also investigate how the policing agents actually do on a day-to-day to deal with anti-social behaviours and crime in two different sites. In order to find out these issues, this study adopted qualitative research methods using in-depth interviews, observations and documentary research. As a result, the two case study sites have some different working strategy but both sites need more investment in increasing number of security officers, up to dated CCTV cameras, equipment and education.

In recent times, an obvious strategy in liner shipping markets that has come to the fore is slow steaming. Nowadays, most liner shipping companies have decelerated the voyage speed to 15-18 knots on major routes, and some leading liner shipping companies have a plan to reduce it to below 15 knots. Slow steaming is helpful in reducing the operating cost and the amount of greenhouse-gas emissions on a single vessel with lower fuel consumption. However, it also creates various negative effects such as the opportunity cost, additional fixed costs and an in-transit inventory cost on a loop. Hence, the net operating cost on a loop is changing dynamically due to the changes of voyage speed based on various slow steaming effects. The aim of this study is to analyze the slow steaming effects in the liner shipping, and to find the best voyage speed that minimizes the operating cost on a loop. Moreover, this study suggests the recommendable strategy for liner shipping companies. To achieve the aim of this study, a simulation model has been designed using System Dynamics.

A novel strategy based on a zero common mode voltage pulse-width modulation (ZCMV-PWM) technique and zero-sequence circulating current (ZSCC) feedback control is proposed in this study to eliminate ZSCCs between three-level neutral point clamped (NPC) voltage source inverters, with common AC and DC buses, that are operating in parallel. First, an equivalent model of ZSCC in a three-phase three-level NPC inverter paralleled system is developed. Second, on the basis of the analysis of the excitation source of ZSCCs, i.e., the difference in common mode voltages (CMVs) between paralleled inverters, the ZCMV-PWM method is presented to reduce CMVs, and a simple electric circuit is adopted to control ZSCCs and neutral point potential. Finally, simulation and experiment are conducted to illustrate effectiveness of the proposed strategy. Results show that ZSCCs between paralleled inverters can be eliminated effectively under steady and dynamic states. Moreover, the proposed strategy exhibits the advantage of not requiring carrier synchronization. It can be utilized in inverters with different types of filter.

국내의 많은 대학들은 매년 교육전산망에서 망 서비스 업자를 공개 입찰로 선정한 결과에 따라 교내망을 자신에 맞게 다양한 방법으로 외부망과 연결시키고 있다 그런데 이들 중 특히, 여러 외부망을 연동시키는 대학에서는 연동 비율에 따라서 전산망 운영 방식을 결정하는데 있어 보다 복잡한 문제에 부딪치고 있다. 따라서 이러한 대학들은 자신의 전산망 운영 방식을 보다 적합하게 결정할 수 있는 지원체계가 시급하다. 본 논문은 전국의 대학전산망 운영자를 대상으로 한 트래픽 관리에 대한 설문조사를 바탕으로 하여 회선 이용율에 기반한 트래픽 효율성을 분석하였다. 그리고 이를 이용하여 두 사업자를 동시에 채택하고 있는 대학의 효율적인 외부망 연동 전략 방안을 제시한다.

Each university in Korea has connected its campus network to outer network with a variety methods since every year KREN adopted an open bid in selecting a network service company. In particular many universities connected two or more outer networks have faced more complex decision problems about their network operations due to the intricacy of the networks. So, those university needs the system which helps the managers to select the optimum operating method for their campus networks. In this paper, campus network traffic efficiency based on utilization was analyzed using the manager's answers to the questions for traffic management. And, by the result of analysis, the link strategy to outer networks was suggested for the universities running simultaneously two outer networks.

This paper proposes a maximum torque operation strategy for the direct torque control of a surface-mounted permanent-magnet synchronous motor (SPMSM). The proposed method analyzes the available operation region of the stator flux of the SPMSM under voltage and current constraints. Based on this analysis, the optimal stator flux trajectory that yields the maximum torque is obtained across the entire operation region, including constant torque and constant power regions. The proposed strategy is also applicable in the flux-weakening region II operation of the SPMSM, which has no speed limit. The validity of the proposed method is verified through experiments conducted on an 800 W SPMSM drive system.

Recreation forests are in the spotlight as the place for personality development, mind and body comfort, companionship, and environment education in forests and valleys. Visitors to recreation forests have been on the increase along with booming in recreation forest building since 1988. Recreation forests are being categorized according to some features such as regional and environmental condition. Recreation forests, however, have not met the expectations of some visitors who want to take a rest with calmness due to the influence of the 5-day-work-week system, increasing interest in rest, leisure, and well-being, and users converge during weekends, summer, and the tourist season. In order to improve visitors' satisfaction efficiently, this study surveyed the level of satisfaction in each cluster based on the precedent study which had classified 85 national or public recreation forests in Korea into clusters. Questionnaires were distributed properly to each cluster and, of the 1,132 questionnaires collected, 1,015 were valid and used for analysis. Reliability of questionnaires and statistical validity of the model were verified. As a result, there are meaningful differences in the ranking of independent variables which affect the level of satisfaction according to clusters. Variables in rest and fatigue recovery have the strongest influence on the level of satisfaction in the clusters of potential factor, internal activation factor, and mixed potential capacity factor. In the use performance and visiting condition factor cluster, appropriateness of visit cost is most influential and, in the education cluster, connectivity with tourist attractions around it is most affective. These results can provide priority in services and maintenance of recreation forests for improving the level of satisfaction and differentiate the distribution of resources according to clusters.

In this paper, we have developed an hourly operating strategy for Direct load control (DLC) considering the efficiency of DLC program and increasing the utility of DLC resource. According to the operating code for DLC, the DLC center should curtail the load for 4 hours when the control notification has been enforced. Since the above strategy may limit the participation of entities, who intend to take part in the DLC program, the new strategy to mitigate the above limitation is required. In this paper, we have developed the operating strategy of DLC program and the mechanism to apply the proposed strategy in the DLC center. The proposed strategy makes the important role from the view of guaranteing the effective alternative raising the participation and avoiding the penalty of the entities.
