To reduce labor market discrimination, there are lively discussions about the role of extant labor regime based on labor unions. It includes both the critical perspective on extant labor movement and the necessity of new actors for resolving discriminations within labor market. Among new actors, the present study focuses on contingent labor centers. Specifically, we have investigated on the development and identity of contingent labor centers as coalition of local government-labor organization. The core content of this study is to reconstruct the activities and strategies of contingent labor centers throughout the longitudinal approach. From many evidences, we can confirm that contingent labor centers have evolved via three phases such as differentiation, de- politicizing, and networks. This finding also provides insights about inside relationships between contingent labor centers and outside tensions between contingent labor center and extant labor organizations. We finally discuss on the theoretical implications of contingent labor center as new actor for contingent worker movement.

Lessons Learned(LL) is a military term defined as all activities that promote future development by finding problems and need improvement in education and reality in the field of warfare development. In this paper, we focus on presenting actual examples and applying AI analysis inference techniques to solve revealed problems in promoting LL activities, such as long-term analysis, budget problems, and necessary expertise. AI legal advice services using cognitive computing-related technologies that have already been practical and in use, were judged to be the best examples to solve the problems of LL. This paper presents intelligent LL inference techniques, which utilize AI. To this end, we want to explore theoretical backgrounds such as LL analysis definitions and examples, evolution of AI into Machine Learning, cognitive computing, and apply it to new technologies in the defense sector using the newly proposed L²-OODA ensemble algorithm to contribute to implementing existing power improvement and optimization.

The duplex system has been considered as an important slip-transfer mechanism to evaluate the evolution of orogenic belts. Duplexes are generally found in the hinterland portion of fold-thrust belts and accommodate large amounts of total shortening. Thus, understanding its geometric and kinematic evolution can give information to evaluate the evolution of the entire orogenic belt. Duplexes are recognized as closed-loop thrust traces on map view, indicating higher connectivity than imbricate fans. As originally defined, a duplex is an array of thrust horses which are surrounded by thrust faults including the floor and roof thrusts, and imbricate faults between them. Duplexes can accommodate regional layer-parallel shortening and transfer slip from a floor thrust to a roof thrust. However, an imbricate fault is not the only mean for layer-parallel shortening (LPS) and displacement transfer within duplexes. LPS cleavages and detachment folds can also play the same role. From this aspect, a duplex can be divided into three types; 1) fault duplex, 2) cleavage duplex and 3) fold duplex. Fault duplex can further be subdivided into the Boyer-type duplex, which was firstly designed duplex system in the 1980s that widely applied most of the major fold-thrust belts in the world, and connecting splay duplex, which has different time order in the emplacement of horses from those of the Boyer-type. On the contrary, the cleavage and fold duplexes are newly defined types based on some selected examples. In the Korean Peninsula, the Yeongwol area, the western part of the Taebaeksan Zone of the Okcheon Belt, gives an excellent natural laboratory to study the structural geometry and kinematics of the closed-loops by thrust fault traces in terms of a duplex system. In the previous study, the Yeongwol thrust system was interpreted by alternative duplex models; a Boyer-type hinterland-dipping duplex vs. a combination of major imbricate thrusts and their connecting splays. Although the high angled beds and thrusts as well as different stratigraphic packages within the horses of the Yeongwol duplex system may prefer the later complicate model, currently, we cannot choose one simple answer between the models because of the lack of direct field evidence and time information. Therefore, further researches on the structural field investigations and geochronological analyses in the Yeongwol and adjacent areas should be carried out to test the possibility of applying the fold and cleavage duplex models to the Yeongwol thrust system, and it will eventually provide clues to solve the enigma of formation and its evolution of the Okcheon Belt.

소셜벤처는 기존의 일반적인 벤처기업과 달리 기술, 경영 혁신 등의 방법으로 경영 활동을 수행하는 기업 형태에 사회적 가치를 추구해야 하는 기업 형태를 결합한 조직이다. 소셜벤처에게는 창업 초기의 전략 수립과 이에 따른 비즈니스 모델 설정이 일반 벤처보다 더 어려울 수밖에 없는데 이는 소셜벤처들이 경제적 가치 추구와 함께 사회적 가치를 동시에 추구해야 하는 소셜벤처만의 이중적인 사업 목적을 가지고 있기 때문이다. 이런 이중적인 사업 목적을 달성하기 위한 새로운 또는 효과적인 사업 전략의 필요성이 대두되고 있으며, 관련 그룹들을 플랫폼에 모아 네트워크 효과를 창출하고 새로운 기업생태계를 구축하는 플랫폼 전략(Platform Strategy)이 주목된다. 본 논문에서는 국내 소셜벤처중에 점프!라는 기업의 사례를 주목하게 되는데 이 회사는 2011년 5월에 창업한 이래 현재까지 지난 7년동안 사업의 내용과 규모를 확장하면서 지속적인 성장을 이루어 냈기 때문이다. 그런데 이러한 성장의 배경에는 타 소셜벤처가 시도하지 않았던 플랫폼 전략을 시도하여, 다양한 참여자들을 유인하고, 이들이 새로운 혁신과 성장을 리드하였다는 것이 큰 작용을 했다는 사실이 존재한다. 본 논문을 통해 소개되는 소셜벤처 점프!의 창업과 성장 사례를 통해서 소셜벤처에게 창업 초기부터 플랫폼 전략을 적용하는 것이 지속 가능한 성장에 유의미한 효과를 발생시키는지를 알아보고 기업생태계를 넘어 사회전체적인 생태계를 통한 사회적 대공진화를 논의해 보고자 한다.

2010년과 2011년의 관측시즌에 총 23일의 BVR 측광 관측을 통하여 처음으로 얻은 2세트의 BVR 광도 곡선을 분석하였다. 새로운 두 세트의 BVR 광도곡선은 제1식과 제2식의 깊이가 거의 비슷하지만, 식바깥 부분에서 관측 시즌에 따라 서로 다른 모양의 잘 발달된 파형 모양을 보인다. 이는 BD And가 흑점이 활동이 매우 심한 짧은 주기의 RS CVn형 식쌍성임을 나타내는 것이다. 우리의 극심시각을 포함한 모든 극심시각을 분석하여 BD And의 공전주기가 규칙적으로 변하는 것을 발견하였다. 이 변화를 보이지 않는 제3천체에 의한 광시간 효과로 가정하여, 궤도이심율이 0.83이며, 9.15년의 주기를 가진 광시간 궤도를 결정하였다. Wilson-Devinney 쌍성 모형을 이용하여 흑점과 제3광도를 고려한 두 세트의 광도곡선 해를 산출하였고, BD And의 절대량을 구하였다. 식바깥의 파형 모양의 변화는 주성의 표면에 매우 큰 두 개의 흑점과 그 위치와 이동으로 잘 설명되며, 전체 광도의 약 15%에 해당되는 제3광도가 검출되었다. 주기연구에서 구한 제3천체의 궤도요소와 제3광도의 결합으로 제3천체의 질량과 궤도경사각을 유추하였다. BD And의 성분별의 평균 나이가 등연령 곡선으로부터 태양과 비슷한 4.6${\times}$109년으로 산출되었다. BD And를 포함하여 현재까지 알려진 짧은 주기의 RS CVn형 쌍성들의 H-R도가 항성진화 경로와 함께 제시되며, 그 천체물리학적 의미를 살펴본다.

Recently, Economic spaces around the world have changed dynamically. Creative arts and cultural actors have begun to emerge in old industrial neighborhoods of major metropolitan cities. These new actors can be seen as creative actors in arts and culture, as well as non-economic actors that have been somewhat overlooked in the traditional approaches of economic geography. They contribute to overcoming regional economic crisis, as these actors bring a particular deviant and creative atmosphere in the neighborhood. Especially, informal gatherings of artistic communities play a pivotal role in knowledge platforms for dynamics of knowledge creation and creativity, which has a significant effect on shaping a creative milieu in the initial stage of formation of a regional ecosystem. In this regard, this paper will investigate the fundamental mechanisms and driving forces of urban spatial restructuring through a case study of the creative arts and cultural ecosystem in Seongsu-dong, Seoul, Korea. Thus, the main purpose of this study is to identify the formation process and key drivers behind the development of the early arts and cultural ecosystem in Seongsu-dong from an evolutionary perspective.

Landscapes and gardens have emerged as an important medium of practice in contemporary cities. Among them, this paper examines the city through the frame of gardens. This is because gardens are being reconceptualized as a medium of activity for urban residents and have become an important subject of action in urban regeneration and the creation of urban villages. From this perspective, this paper examines and proposes an "integrated garden city theory" as a landscape theory suitable for the contemporary era by focusing on the urban structure and the behavior of urban residents through the medium of gardens, as well as the process and results. This is both a process and a result of looking back at the evolution of landscape for over a century and rethinking the identity of landscape. We first examined garden city theory, noting that Ebenezer Howard and Frederick Law Olmsted's positions on the relationship between gardens and cities were not so different, and that "working and responsive landscapes" were fundamental to cities and the beginning of landscape theory. We also examine how their ideals have not been fully realized in cities over the past century, but the prototype of gardens based on traditional garden culture is now being formed in East Asian cities, and the evolution of landscape theory in response. The conclusion is that a new version of the garden concept should be reestablished as a living infrastructure in our cities, and a new garden city theory is needed to make it work. To this end, each chapter examines three arguments, as follows First, the values of gardens and East Asian garden cultures in contemporary cities are shaped by the themes of community and integrity. Second, Korean communality, represented by apartments, is expressed through gardening and requires the reconciliation of city and life and the role of landscape architecture as a specialized field to support it. Third, we examine and consider an integrated garden city theory as a theory of practice in which city-based, everyday life, and garden mediums, i.e., city, life, and garden, are organic, based on an oriental view of nature. As a result, it is confirmed that contemporary gardens and cities are looking for important elements and values that still need to be rediscovered in East Asian landscape and garden cultures. Although the proposal of an integrated garden city theory cannot guarantee the continuation of landscaping, it can be an opportunity for all fields related to cities, not just landscaping, to collaborate and consider garden cities. Through this, it is hoped that "the concept of garden and city suitable for metropolitan or dense cities, ways to spread and support garden culture based on community, evolution of landscape theory/design theory suitable for lifestyle and terrain conditions, search for sustainable/resilient garden city theory that can respond to climate change, and establishing a new role for landscape in the 21st century" will be seriously considered.
