This paper's purpose is to get hold of the recent research trend by analyzing the variables uesd in startups related papers. The startups related papers in this paper are the papers which include 'startups' in the title of the registered papers from the year 2013 to the year 2020. This study's analysis methods are text-mining of all variables and text-network analysis of affected variables. Visualizing tool for network analysis is Gephi. The result of variables' analysis is as follows. First, independent variables consist mainly of variables about startups' internal factors and outside environment, but due to startups' features like early stage company's features, innovative features, most of variables are about enterprise internal competitiveness, marketing 4P strategy, entrepreneurship, coopreation method, transformational leadership, enterprise features, lean startup strategy, enterprise internal communication, value orientation, task conflict, relationship conflict, knowledge sharing, etc. Second, dependent variables are mainly about outcome, and are classified into financial performance and non-financial performance by overall concept. In other words, startups related papers have higher interest in non-financial performance, like management performance, team performance, SCM performance as well as financial performance like sales quantity owing to startups' immaturity in getting good financial performance. Through this study we can find out as follows. Although there are not many officially registered papers dealing with startups, those papers include various themes about stratups. For example, there are trendy themes like lean startups strategy, crowdfunding, influencer and accelerator, etc.

The proportion of apartment housing has been increased to solve the housing problems resulted from rapid growth in urban population and urban economy. With the increase in apartment's proportions and the concern about quality of housing, the contractors have made efforts to satisfy the customers in improving the quality of housing. Despite these efforts, the conflicts between the contractor and the customers are getting serious. Also the disputes and the litigation of defect are increasing because of the contractor's negative treatment and inadequate countermeasure. In this study the defect lawsuits which bring actions against the contractors are collected and analyzed. And then the strategic countermeasures are proposed according to the classifying the type of defect and size. The suggested countermeasure model before the defects are resulted is expected to contribute in developing the contractors strategies to reduce the conflicts against customers.

This thesis analyzes the backgrounds of the third offset strategy of the US Department of Defense. The key technology areas to be developed and the implications of the 3rd strategy are also examined. The potential great powers, China and Russia have catched up with US in the certain areas of military technologies. The technological superiority of US military is found to have been eroded. The US DOD needs a new defense policy called the 3rd offset strategy to meet this new challenge. The 5 basic technology areas were identified; learning machines, human-machine collaboration, machine-assisted human operations, human-machine combat teaming, and autonomous weapons. The 3rd offset strategy should be managed not to move to the new arms race with rivalries. The defense acquisition system also needs to be improved for the smooth flow of the advanced commercial technologies to the defense sector. Korea needs to figure out the possible technologies of co-research and development with US.

Giving behavior promotes social solidarity and lessens social deprivations by voluntary practices to make better communities. Despite the increasing trend of giving in terms of participation and amount in Korean society, the giving culture has deeply rooted in charitable emotion based on compassion, still far from social solidarity. This paper attempts to identify giving behavior by investigating its characteristics and changes in its motives from the compassion-based social welfare to social responsibility and community solidarity, centering around 'Yellow envelope campaign' started in 2014 to support the living expenses and cost of litigation for the fired workers of Ssangyong Motors. By employing questionnaire survey and in-depth interview, it analyzes the horizontal relationships, reciprocal responsibility, social capital, and pursuit for conflict solution. Even though the campaign didn't change our society as a whole, but it cast the social questions on the birth of social empathy and solidarity.

The purpose of this study is to resolve the factors that affect happiness levels and l Considering the increasing importance of maintaining and developing the careers of working mothers, this study sought to analyze the effect of the meaning of work (MOW) and child-based self-worth (CBSW) on the work-family interface and career commitment. This is the first exploratory study to examine MOW and CBSW as resources for working mothers. For 10 days, starting August 18, 2020, 309 working mothers were asked to complete a questionnaire commissioned by a professional research institute, and 250 valid samples were then analyzed. The analysis found, first, that MOW had statistically significant positive effects on work-family enrichment and family-work enrichment and a negative effect on work-family conflict. Second, CBSW had a positive effect on work-family and family-work conflicts. Third, work-family enrichment had a positive effect on career commitment, while work-family conflict had a negative effect on career commitment. Finally, the mediation effects of the three paths were determined: MOW→work-family enrichment→career commitment; MOW→family-work enrichment→career commitment; CBSW→work-family conflict→career commitment. These results suggest that, to better manage the career commitment of working mothers, attention should be paid to the MOW, CBSW, and work-family interface.

최근 증가하고 있는 기후변화에 의해 설계빈도를 상회하는 강우의 발생빈도가 증가하고 있으며, 이로 인한 도시유역의 내수범람 피해가 증가하고 있다. 도시유역에서 발생하는 침수 피해의 경우 인적 물적 자원이 집중되어 있는 도시의 특성으로 인해 침수로 인한 직접적 피해 규모가 상당할 뿐만 아니라 침수 발생 후 세균 및 박테리아에 의해 발생하는 수인성 전염병의 유행 등과 같은 2차적 피해 또한 심각한 사회적 비용을 초래할 수 있어 도시유역의 침수 피해를 저감시키기 위한 대책이 절실히 요구되어지고 있다. 도시유역의 침수를 예방하기 위한 대책은 구조적 비구조적 대책으로 구분되어 질 수 있으며 구조적 대책의 경우 침수 피해 예방에 직접적인 효과를 낼 수 있다는 장점이 있으나 대규모 사업예산 및 사업 기간으로 인해 직접적 효과를 보기까지 상대적으로 긴 시간이 필요할 뿐만 아니라 사업 진행 중 대상지역 거주민들의 민원으로 인한 갈등 조정 등으로 인해 사업실행에 어려움을 겪고 있다. 이러한 측면에서 비구조적 대책의 일환인 수치해석을 통한 침수피해 재현 및 침수원인 파악을 통한 구조개선 제안은 구조적 대책의 단점을 보완할 수있는 좋은 대안이 될 수 있다. 도시유역의 경우 비도시유역과 대조적인 차이점으로는 높은 비율의 불투수층, 복잡한 지형, 다수의 인공 구조물 및 배수관망 시스템 등을 들 수 있으며, 침수해석 모형의 정확도를 높이기 위해서는 복잡한 지형의 효율적인 처리가 무엇보다 중요하다. 일반적으로 이용되는 2차원 침수해석 모형들은 직교구조 격자 또는 비구조 격자를 이용하여 지형을 묘사하고 있으며 DEM 자료를 직접 사용하는 직교구조 격자의 경우 지형 데이터 생성이 상대적으로 쉽다는 장점이 있으나 복잡한 지형을 표현하기 위해서는 불필요한 지역까지 높은 해상도를 이용해야 하며 이로 인하여 모의시간이 지나치게 길어지는 문제점이 발생한다. 비구조 격자의 경우 상대적으로 복잡한 도시 유역을 잘 묘사할 수 있다는 장점이 있으나 격자망 생성에 필요한 데이터가 많고 격자망 생성에 지나치게 많은 시간과 노력이 소요된다는 단점이 있다. 따라서 본 연구에서는 위에서 언급한 두 가지 방법의 장점만을 취할 수 있도록 메쉬 세분화 기법을 이용한 2차원 침수해석 모형을 개발 하여 복잡한 지형은 고해상도 메쉬를 이용하여 보다 자세히 묘사하고 상대적으로 복잡하지 않은 지형은 저해상도 메쉬를 이용하여 계산시간을 단축시킬 수 있도록 하였다. 수치해석 기법으로는 엇갈림 격자를 이용하는 Leap-Frog 기법과 유한차분 (Finite difference Method)기법을 이용하였다.

Band Wittgenstein is a relatively band-shaped team since Shin Hae-Chul's previous big band "Next." The album, which features Shin Hae-Chul's unique lyrics and specific concepts, is also similar to the Next albums. However, there is a difference in sounds used on the album that are properly fused sampling based work and computer music. This album is a low-budget home recording album produced at a total cost of 3 million won. Shin Hae-Chul was in charge of the main vocals and programming, and all of the works were done together by the band members. In this album, Shin Hae-Chul focused on teamwork rather than producing his own music. The low budget could have been a constraint on music production, but it must be highly appreciated for it being a novel attempt. Musicians who create music always create conflicts between their favorite music and popular ones. However, without creative efforts, there is no evolution or development in the music industry. It is clear that constant changes can continue to develop musical ability, which leads to the development of Korean pop music.

We paid attention to the fact that a project will always tend to increase in size even if its scope is narrowing. The complexities and multidisciplinary aspects of projects require that the many parts should be put together so that the prime objectives- performance, time, and cost- are met. These aspects lead to the use of teams to solve problems that used to be solved by individuals. Firstly, We surveyed the design companies and their clients on the design projects, and categorized the design task into 5 phases, that are marketing, planning, idea development, presentation, and follow-up. Among the phases, the presentation has the most difficult task, longest processing time, and highest cost, whereas idea development phase has relatively low cost, longer processing time, and more difficult task. Most of the companies used to be faced several bottlenecks on their design projects - time control, budget control, and resource control. Secondly, for improving the project managing process, we adopted that dividing and analyzing the sub critical paths may help in the effective managing.(Badiru, Adedeji B., 1995) Some critical paths require almost as much attention as the critical path since they have a high potential of becoming critical when changes occur in the network. Therefrom we suggest the Total task weight(Gt) as a management formula for the design project management.${Gt=\mathrm{T}\ast\leftthreetimes\ast1/100}$<\TEX> ( Gt = Total task weight, mathrm{T} = Task Weight, \leftthreetimes= Criticality ) Thirdly, In order to support to managing for the design projects, we set up an application system, which is graphically planning and implementing a complex undertaking. It is helpful to make the control of a project easy. The DPMS(Design Project Management System), which has two sub system. One is Project Screening System(PSS), and another Project Managing System(PMS). In PMS, we divided the design project into three modules; Project Planning, Project Implementation, and Project Evaluation. As a result, the DPMS will contribute to supply the control of a project easily and effectively. Also teams are used for making decisions and taking action with the DPMS. But we need to get further studies on the relationships between the whole project and its tasks.
