Exploring the distant universe by observing various astronomical objects and extending knowledge on the cosmos by applying human intuition and reasoning to observations are astronomers' professional activity. Astronomers are the people born under a lucky star since this elegant and beautiful job is their the only duty. Being in the 21st century we astronomers now know that galaxies are holding evolving stars and gas, and distribute in the infinite spacetime in an interesting way revealing the secrets of the beginning of the universe. Cosmic structures such as galaxies, large-scale structures, and cosmic microwave background fluctuations are also the tracers of the expansion of space and the invisible components of the energy contents of the universe. Unlike the past century we are in a situation where integral knowledge on various cosmic structures as well as that on a variety of observational and analysis tools are available to everyone and often required for our special mission. However, my experience made me think that accumulating critical questions on nature driven by curiosity is vital for researchers and far more important than absorbing knowledge from others and books. Transforming one's own question marks to acclamation marks is the reward of our life. That is THE fun.

Recently, a lower levels space has turned into a mediating space where people can experience urban spaces directly and it has revitalized communication between the city and company and also it has changed itself newly. In addition, this space which is connecting interior and exterior spaces of company's buildings can attract people living in the downtown as shock-absorbing and transitional space and it is getting more important part in urban context these days. Through case studies of corporate office space planning characteristics derived lower levels and to provide direction for the lower levels of the corporate office space planning purposes of the present study. Therefore, I establish the concept of the public good corporate office space and transition space, the concept of transition through the first Theoretical Methods. I investigate the properties of the transition area is used as the target for completion of the current construction culture destination since 2000, winning the corporate office, I have been talking about the characteristics of the corporate office along the lower part of the last PPS assessment criteria to apply to the building. PPS by applying an assessment factor can be derived for building enterprise case studies and analysis of the results the following conclusions about the use of publicity and transition space. First, lower levels of corporate office space had been applied to the use and activity in a very important project characteristics. Second, corporate office space, lower levels of access and linkages are important. Finally, in terms of public characteristics transition space is a important characteristic for low-rise space of headquarter buildings.

현대 사회는 다양한 정보 기술들이 유기적으로 연결되고, 커뮤니케이션 테크놀러지의 급속적인 발전으로 인해 뉴 미디어의 디지털화가 이루어짐에 따라 고도의 정보화 사회가 현실화되었다. 이러한 디지털 미디어 중에서도 웹의 등장은 가히 혁명적인 사건이라 할 수 있다. 단순히 텍스트만으로 구성된 서비스를 제공했던 웹에서 이용자나 사용자에게 이미지와 오디오, 동영상 등을 전달할 수 있는 웹의 발전은 새로운 경험을 제공하게 된 것이다. 이러한 발전이 가능하였던 것은 웹이 다양한 미디어를 리미디에이션 하는 것이 가능한 미디어적 특성을 가지고 있기 때문이다. 신문이나 잡지 등의 인쇄매체부터 TV, 오디오, 영화 등의 음향, 영상매체에 이르기까지 다양한 미디어들이 웹에 의해서 차용, 경쟁, 개선, 공격, 흡수의 형태로 리미디에이션 됨에 따라 우리는 각 미디어들의 특성을 웹이라는 한 가지 매체를 통해 누릴 수 있게 되었다. 본 연구는 미디어의 리미디에이션에 대한 이론적 고찰을 중심으로 웹디자인에서의 리미디에이션에 대한 사례연구를 통해 이의 효용성을 파악하여, 효과적인 표현방법을 모색하고 향후 리미디에이션의 발전 방향에 대해 연구하였다.

A control rod drive mechanism(CRDM) is a reactor regulating system, which inserts, withdraws or maintains a control rod containing a neutron absorbing material within a reactor core to control the reactivity of the core. The top-mounted CRDM for Jordan Research and Training Reactor(JRTR) with 5 MW power has been designed and fabricated based on the HANARO's experience through KAERI and DAEWOO consortium project. This paper describes the performance qualification test results to demonstrate the operability of a prototype and four production CRDMs during the reactor lifetime. The driving performance, the drop performance and the endurance tests for CRDM are carried out at a test rig simulating the actual reactor conditions. A vibration of internal components due to the coolant flow is also measured using a laser vibrometer. As a result, the CRDMs are driven having a good driving performance without a malfunction between command and output signals for the stepping motor. Also, the pure drop time and the impact acceleration are within 0.72 s and 4.2 g to meet the design requirements, and the vibrational displacement of control rod is measured as maximum $5.2{\mu}m$.

소셜 네트워크 게임(SNG)은 기존의 경영 시뮬레이션 장르에 소셜 네트워크의 접목으로 특히 많은 여성 유저에게 환영받고 있다. 따라서 SNG의 플레이 동기나 구체적인 몰입 요소, 특히 게임 속 공간 꾸미기 콘텐츠에 초점을 맞춘 연구의 필요성이 대두되었다. 본 연구는 SNG의 공간 꾸미기 콘텐츠 이용 경험과 구체적 이용 동기에 관한 연구이다. SNG를 이용하는 유저의 태도를 관찰하고, 이를 Q 방법론을 통해 유형화하였다. 또한 SNG의 공간 꾸미기를 이용하는 유저의 구체적 동기를 분석하였다. 연구 결과, 대다수의 유저들이 SNG의 사회적 교류 요소보다도 공간 꾸미기 콘텐츠에 몰입하며 게임의 지속적 이용에 영향을 미치는 것으로 확인되었다. 이런 몰입 현상은 유저의 자기표현 욕구와 관련되어 있다는 사실을 증명하였다.

The covid 19 pandemic led to an economic collapse and multiple impacts upon Argentina's labour dynamics. As well as in other parts of the region, falls in employment rates (both due to an increase in unemployment and significant withdrawals from the labour force) were combined with wage reductions for those who were able to keep their jobs. Thus, two important processes for the labour market complimented each other: a structural shock associated with a tasks automation as a reorganisation and substitution of factors, with a cyclical recession caused by the pandemic. The international experience shows the amplifying impact the latter has on the former, generating long-term consequences mainly in routine-intensive jobs. However, the knowledge-intensive services sector appears to be the most capable of cushioning the recessionary shock (both in terms of wages and labour absorption), even with nuances within the sector depending on the extent of the shutdown measures and its capability to switch to remote work. Finally, the task approach is decisive in capturing the ability to adapt both the cyclical and structural processes, absorbing a large part of the explanatory potential that sectoral classifications tend to bring about.
