Culture and art can be said to be an important medium that enhances people's creativity and satisfies our desire for cultural experience as well as emotional cultivation. These arts and culture are spreading all over the world through Hallyu, etc. to this day, and it is naturally positioned as an industry that creates the highest added value. However, rapid industrialization and development of industrialization also provided many negative causes, such as damage to nature due to the decline of factories and equipment industries, pollution and damage to the surrounding environment due to the use of fossil fuels. Therefore, in this study, we investigated the factors necessary for improving the image of the local community and maximizing tourism classes by actively utilizing the idle space abandoned due to industrialization and industrialization as a complex space for culture and art. As a result, empirical analysis was conducted through a total of six factors excluding typology through factor analysis. The results showed that reliability, certainty, and empathy had a positive effect, but responsiveness did not. In addition, the economic effect was found to have a positive effect on customer satisfaction.

This study analyzes the impact of the experiences of elderly using social welfare organizations in socio-economic deprivation on their relational aggression damage experiences, and verifies the mediating effects of rejection sensitivity. For data collection, 275 of 290 questionnaires, excluding 15 questionnaires with inadequate responses, were used for the final analysis. The SPSS and AMOS programs were used for data analysis through the following procedures. The analysis showed that socio-economic deprivation experiences, relational aggression damage experiences, and rejection sensitivity were higher for the groups of male elderly, higher age, education above college, absence of spouse, and longer institutionalization. The size of indirect effect (${\beta}=.32$) was larger than that of direct effect (${\beta}=.14$), signifying that the indirect impact through rejection sensitivity was larger than the impact of socio-economic deprivation on the experiences of damage by relational aggression. With the above findings, this study makes practical suggestions for institutional measures to reduce the elderly's relational aggression damage experiences and rejection sensitivity and programs on socio-economic deprivation, etc.

대한민국은 2017년 이후 저출산·고령화사회로 진입하였고 생산가능인구가 감소함에 따라 노동생산성이 낮아지고 있으며, 여성의 경력단절 문제가 심각한 사회문제로 대두되고 있다. 정부에서는 여성가족부와 고용노동부가 함께 여성의 경력단절 예방과 해결을 위해 다양한 지원창업과 경제활동을 장려하고 있지만 현실에서의 재취업장벽과 열악한 노동환경, 일과 가정의 양립 문제 등으로 인해 경력단절 여성들 특히, 고스펙·고학력의 여성들은 취업이 아닌 창업을 선택하고 있으나 창업의 성공률은 그다지 높지 않아 다양한 대비책이 요구되는 실정이다. 여성 기업가는 창업부터 성장하기까지 수많은 위험요소에 노출되어 있으며 이러한 위험요소를 체계적으로 관리하고 극복하는 노하우를 쌓아 잘 활용하였을 때 경제활동의 핵심주축으로 성장할 수 있으며 창업이라는 혁신적이고 생산적인 활동으로 전환해 일자리 창출 및 기업의 혁신과 나아가서는 국가경제발전에 기여할 수 있는 토대가 될 수 있다. 본 연구의 목적은 여성의 기업가정신이 창업성과에 미치는 영향을 실증 분석하는데 있다. 경력단절여성 창업자를 대상으로 기업가정신이 창업성과에 미치는 영향과 회복탄력성이 조절효과를 갖는지 여부를 확인하고자 하였다. 여성기업가 특유의 소비자의 욕구를 세심하고 활동적으로 파악하여 생활밀착형 아이디어가 풍성면모와 창조적인 아이디어를 갖고 적극적으로 실행해보고자 하는 진취적인 성향과 회복탄력성이 창업성과에 영향을 미칠 것이라는 상황에 초점을 두고 연구모형을 설정하였다. 이를 위해, 기업가정신의 구성요소를 '혁신성', '진취성', '위험감수성'을 독립변수로 구성하였고, 창업성과의 주요구성요소인 '재무성과', '비재무성과'를 종속변수로 설정하였다. 또한 회복탄력성을 조절변수로하는 연구모형을 상정하였고 이는 여성의 기업가정신과 창업성과의 관계에서 회복탄력성의 조절효과여부를 확인하여 여성의 기업가정신교육과 회복탄력성의 중요성을 밝히고 활성화를 목적으로 하고 있다. 본 연구는 여성의 기업가정신이 창업성과에 긍정적 영향을 미친다는 것을 규명했다는 점에서 시사점을 갖는다. 심각한 사회문제로 떠오르고 있는 여성의 경력단절 문제를 해소하기 위해 향후 중소벤처기업부 및 여성가족부, 고용노동부 등에서는 여성창업자를 대상으로 체계적인 기업가정신교육과 회복탄력성에 관한 교육을 시행할 것을 제언한다.

Economic feasibility is one of the most important factors in energy production from regenerative biomass. From the aspect, biogas from anaerobic digestion of wastewater sludge is regarded as the most economical because of its cheap substrate and additional income from the disposal of waste sludge. Sludge hydrolysis has been regarded as the rate limiting step of anaerobic digestion and many sludge pre-treatment technologies have been developed to accelerate anaerobic sludge digestion for enhanced biogas production. Various sludge pre-treatment technologies including biological, thermo hydrolysis, ultrasonic, and mechanical methods have been applied to full-scale systems. Sludge pre-treatment increased the efficiency of anaerobic digestion by enhancing hydrolysis, reducing residual soilds, and increasing biogas production. This paper introduces the characteristics of various sludge pre-treatment technologies and the energy balance and economic feasibility of each technology were compared to prepare a guideline for the selection of feasible pre-treatment technology. It was estimated that thermophilic digestion and thermal hydrolysis were most economical technology followed by Cell rupture$^{TM}$, OpenCEL$^{TM}$, MicroSludge$^{TM}$, and ultrasound. The cost for waste sludge disposal shares the biggest portion in the economic analysis, therefore, water content of the waste sludge was the most important factor to be controlled.

With a substantial rise in divorce rates since the mid 1990s, single-parent households are increasing rapidly in Korea. Often it is believed that children in single-mother households suffer the most economically and socially with the marital disruption of the parents. This study hypothesizes that in Korea the socioeconomic status of single-father households may be lower than that of single-mother households mainly because low-income divorced women are not able to form their own households with children. The analysis is based on two sub-samples from the 2% sample of the 2005 Census, one, with children 12 years old or younger and, the other, with divorced mothers of children of the same ages. The findings support the hypothesis that previously-married single fathers show the lowest educational and occupational status among 6 groups of parents: fathers and mothers from two-parent families, fathers and mothers from married but spouse-absent families, and previously-married single fathers and mothers. Divorced mothers'likelihood of living apart from their children has a strong negative association with their educational attainment, with the highest likelihood among women of middle school or lower education and the lowest likelihood among women with college education. Although single mothers comprise a larger percentage of single-parent households, single-father households demonstrate a particular vulnerability with their weak socioeconomic status.

현재 우리사회에서 보 차도용 콘크리트 블록은 흔하게 볼 수 있는 토목 자재중 하나이다. 보 차도용 블록의 패턴은 흔히 2가지에서 5가지 색상을 배치하며 미적 효과를 위하여 디자인된다. 그러나 바닥에 적용되는 보 차도용 블록은 색상 배치를 통한 조경미 창출 외에도 패턴디자인을 통해 방향을 제시하거나 홍보성, 경고성 등의 문구를 담을 수 있고 그 시각적 효과가 뛰어나 기능적인 면에 대한 관심도 커져 가고 있다. 또한 특정한 장소를 필요로 하지 않고 한번 설치되면 외부요인에 의해 디자인이 변하지 않는 특성에 따라 그 효과가 경제적이며 적용성이 뛰어나다. 이러한 패턴디자인을 통한 효과를 분석하여 국내패턴디자인의 개선 방향을 모색하고 더 나은 부가가치를 창출하고자 한다.

배에서는 부식과 쇠모 현상이 해상 상태와 주변 환경에 의해 성장하게 되면 파구가 생기면서 이로 인해 해난 사고의 원천적인 원인이 된다는 사실을 여기서 예를 들어서 기술했다. 이런 이 유로부터 어떤 방법을 사용하든 간에 배의 방식에 관한 배려가 충분히 이루어져야만 하겠으며 그리고 배에서 방식에 대해 어느 정도의 Cost가 들었는가가 배의 경제적인 가치를 좌우한다고 본다. 즉 배에서는 반드시 신조시에는 충분한 방식 대책을 강구를 해서 적절한 보수 관리를 행 하는 방법이 초기 투자액을 확보하는 것보다도 안정성에 부가해서 경제적으로도 상당히 유리하 다는 사실이 상기의 사실로부터 알 수가 있다. 방식 시방도 경년의 열화 현상으로 인해서 산만 해짐이 상당히 큰데 이것도 취항후의 방식 관리에 의존케 되지만 신조시의 방식 검사의 중요성을 충분히 인식하는 것이 매우 중요하다. 그리고 '개발중인 방법'은 일반적인 방법이 아니기 때문에 앞으로 많은 연구가 있어야 하겠다.

This study is focused on confirmation of the usefulness of EVA through the empiritical test of it which is used in practical business as the new performance measures of the VBM(value based management). The results of test are as followed : We could confirm the possibility that the EVA per share could be used as the useful performance measure as it shows the positive relation with the stock prices. The explanatory power showed especially higher than any other cases if the EPS shows positive and the EVA per share shows positive. When we interpret this study, we must keep in mind that the magnitude of the EVA is very different from by organs of publication in our country. Accordingly, the study to confirm the usefulness of EVA must be basically limited. Therefore, to get the useful result through the study related with the EVA, the publication of the trustful EVA must be proceeded by unified standard.

For a successful construction project, systematic and objective decision-making is a prerequisite from the planning and designing stages. However, previous LCC analysis methods have focused only on simple cost savings and the accompanying economic efficacy while missing the environmental aspects of a structure. Although recently, a new approach of integrated $CO_2$ analysis has been introduced, which is more advanced than the existing simple LCC methods, it is difficult to collect all of the data necessary for each evaluation item since the product-specific cost is not presented under the LCC. In this research, cost evaluation items were selected by relatively high weights and items with heavy influence over a decision-making process in order to suggest an LCC-LCA integrated analysis model that is useful in comprehensively assessing the economic cost and environmental cost throughout the whole life cycle of a structure. The developed LCC-LCA integrated analysis model was applied to actual practices and compared with previous methods to test the model's effectiveness.

This study empirically investigates the possible negative relationship between the number of job offers and the job satisfaction in the Korean labor market, using the Korea Labor Income Panel Study, where the number of job offers of young workers are collected in the third wave. Results show that the number of job offers is negatively related to every year job satisfaction, this effect is smaller for higher earning and older individuals, and there is a gender heterogeneity. We discuss that having more job offers does not necessarily increase the workers' utility, which is a general monotonic assumption in the traditional economics. We suggest that having a large number of job offers allowing them to choose the best option can be inefficient itself, and therefore it is better to focus on qualitative matching rather than increasing just the absolute number of job opportunities.
