Purpose: Many people recognize the fact that women are basically poor at financial and retirement planning. A small number of scholars have explored the factors and situations that influence the level of awareness of pre-retirement women and men with regards to planning for their retirement years. In most developing countries, including Malaysia, there are more men in the younger segment of the population and more women in the older segment, since women tend to live longer than men due to having jobs of relatively lower risk, their behaviors, and activities. Research design, data and methodology: Given that it is hard to predict whether they will be healthy in old age, women may require additional resources to obtain the care and assistance that they need. The transition from career life into retirement is a long process for people to go through. Some may be able to prepare for the next stage of life, and some may not be able to prepare due to personal reasons. Planning for future retirement is important because it will affect the quality of a woman's life after a certain age. Results: Without proper planning, women may face financial instability, depression, and poor psychological well-being. However, many women are unaware of their financial status or do not know their family's financial status, such as tracking the main income, budget, and expenses, financial commitments and have no proper record of assets owned, loans owed, or updated loan balances. Conclusions: The findings of this research have led to the conclusion that pre-retiree women are likely to regard their retirement savings as sufficient without realizing that they should have at least several types of savings instead of just one, and the grave consequences of not having any savings at all for their retirement years.

This study aims to examine individual perceptions and lived experiences of the Net generation of student teachers and the previous generation of teachers about their technology use in education. The participants of this study include 106 pre-service teachers and 50 in-service teachers from one teacher education university in Korea. Employing a mixed methodology, we first empirically examined the participants' perceptions toward multiple variables related to technology use in education, namely (a) past ICT experiences in schools, (b) personal computer use, (c) constructivist belief, (d) computer efficacy, (e) attitude toward computer in education, and (f) prospective computer use. In addition, we conducted face-to-face interviews with selected participants for the in-depth investigation of their lived experiences about technology use, beliefs, and attitude. Results indicate that there are significant differences between in-service and pre-service teachers in their prior experiences with technology in schools. However, the pre-service and in-service teachers did not differ significantly in their beliefs, attitude and other technology-related variables, which may indicate the danger of generational determinism in the Net Generation debate. The analysis of interview narratives revealed two major themes about the interplay of one's agency and structural changes in the participants' lived experiences with technology use in education: (a) transition from negative past experiences to opportunities for positive computer use, and (b) attitudes formation and change through apprenticeship experiences and structural influences. In conclusion, this study suggests that the Net Generation debate should move beyond dichotomous or techno-centric thinking. There is a critical need to pay more attention to develop deeper understandings of the fundamental diversity existing within the generation itself. Implications for teacher education are also discussed.

비디오 요약의 첫 걸음은 샷(shot) 변환의 검출이다. 이러한 샷 변환은 점진적인 변환과 급진적인 변환이 있다. 지금까지 급진적인 샷 변환은 이미 주어진 한계치나 연속된 두 프레임의 이미지에 기반을 둔 거리를 이용하여 검출하였고 점진적 변환 또한 일반적으로 한계치를 이용하여 검출하였다. 그러나 한계치에 따라 그 결과가 확연히 달라지고 또한 그 한계치를 정하는 것도 어려운 문제이다. 이 논문에서는 이런 문제의 해결과 MPEG 압축 비디오 상에서 점진적 변화의 검출뿐만 아니라 분류를 해결하는 방법을 제시하였다. 논문에서는 한계치를 사용하지 않은 은닉 마르코프 모델과 MPEG의 근사 DC 값을 이용하여 보다 빠르고 정확한 결과를 얻도록 하였다. 그리고 히스토그램의 차이뿐만 아니라 매크로 블록 (macro block)의 차이라 불리는 새로운 척도를 도입하여 보다 정확한 값을 얻도록 하였다. 은닉 마르코프 모델은 샷, 페이드(fade), 디졸브(dissolve), 컷(cut) 등의 4개의 상태를 갖게 하고 학습은 Baum-Welch 알고리즘으로 필요한 변수들을 추정하였다. 그리고 특정 벡터에 Viterbi 알고리즘을 적용하여 원하는 상태를 얻을 수 있다. 대부분의 실험 결과를 보면 새로 제안한 척도를 사용한 방법이 히스토그램의 차만을 이용한 방법보다 더 좋은 결과를 나타내었으며 이산적 마르코프 모델보다 연속적 마르코프 모델이 좋은 결과를 보여준다.

최근 코로나 바이러스 감염증(COVID19)의 확산으로 다양한 분야에서 대면으로 이루어지던 일상에 대한 변화가 요구되면서 빠른속도로 다양한 활동이 비대면 방식으로 전환되거나 새로운 비대면 활동 방법을 검토하고 있다. 하지만 기존 대면 방식의 활동을 단순히 디지털 기술을 이용해 비대면화하는데 한계가 존재하며 이는 역설적으로 그간 디지털을 중심으로 해결책을 제시해온 UX 디자인 분야에서 두드러지게 나타나고 있으며 협업을 강조하는 UX 디자인 특성에 기인한다. 특히 UX 디자인 분야에서 이해관계자의 의견을 수집하고 아이디어를 도출하는 등 생산적 활동 방법인 워크숍 활동에서 소통과 협업 측면에서 원활한 진행이 어려울 것으로 보인다. 이러한 필요성에 따라 UX 디자인 분야에서 워크숍 활동을 특징을 파악하고 워크숍 활동의 주요 행동에 대해 효과적으로 비대면 전환할 수 있는 방안을 제시하고자 한다. 그 과정에서 닐슨노먼그룹이 정의한 UX 디자인 분야의 워크숍 활동 유형 중 아이디어 생산 및 발산과 수렴 활동이 활발하게 일어나는 디자인 워크숍 유형을 대상으로 하여 표준 프로세스를 도출하였다. 표준 프로세스에 워크숍 활동을 촉진할 수 있는 방법론과 소통 및 디자인 활동 협업을 위한 비대면 서비스를 조합하여 비대면 워크숍 활동을 구성하는 프레임워크를 개발하고 다양한 워크숍 유형에 대응하여 비대면화를 위한 적용 가능성과 효용성을 확인 하였다. 본 연구 결과를 바탕으로 UX 디자인 워크숍 활동에 대해 효율적인 비대면 전환과 워크숍 활동을 통한 이해관계자들의 협업 측면에서 활용을 기대한다.

In the present investigation, a high precision thermal imprint system for micro ceramic products was developed and the net-shape manufacturing of multi-layer ceramic reflector for LED (Light Emitting Diode) was conducted with a precision metal die. Workpiece used in the present investigation were the multi-layer laminated ceramic sheets with pre-punched holes. The cavity with arbitrary angle was formed on the circular and rectangular holes of the ceramic sheets. During the imprinting process, the ambient temperature of the imprint system was kept over the transition temperature of the ceramic sheet and then rapidly cooled. The results in this paper show that the present method can be successfully applied to the fabrication of very small size hole array for ceramic reflector in a one step operation.

During high speed economic growth period in Korea, our society has focused it's energy on the economic and social development based on the strategy of demolition and destruction of all our natural and man-made environment. In progress with that trend, our small cities in Korea also have just followed the metropolitan physical development pattern and considered that imitation of those metropolitan cities' or western cities' changes be the same meaning of "modernization". Therefore, our valuable urban and architectural heritages have been constantly destructed and that situation has been same in Anseong. Now in the new trend of environmentally sustainable urban design and at the new millenium period, we have to focus our attention on the retaining strategy of city's historicity as a city planner or an architect, and the first step for this strategy shall be to clarify the transition process of urban structure, especially of C.B.D. area of small cities since pre-industrial period.

Demographic transition drives changes in consumer demand for food products. This study examines how rising incomes and population trends affect spending on food purchased for home. The objective of this study is to characterize the relationships between selected socio-demographic factors and food selection among South Korean households. Panel data from Rural Development Administration (RDA) in South Korea in 2010 was used (n=971). Household food purchases were classified into one of the five food groups from Composition of Foods of RDA. Multiple regression analysis was used to analyze the effects of household size and income based on the expenditure share on each food group. All statistical analyses were performed using SAS/ PC version 9.3. Results show that household socio- demographic characteristics have a strong influence on food purchasing, with the purchase of vegetables and fruit, and processed food and pre-packaged being particularly sensitive.

We have examined the effect of ball-milling on the superconducting properties of $MgB_2$ doped with C. The ball-milling of pre-reacted $MgB_2$ powder was carried out in dry or wet state using C or diethylenetriamine ($C_{4}H_{13}N_3$) as additives. The diethylenetriamine, whose chemical formula contains no oxygen, was chosen to avoid an excess oxidation during doping. The superconducting transition temperature (Tc) of the ball-milled or doped $MgB_2$ powders was only slightly smaller than that of undoped $MgB_2$. The critical current density (Jc) of the highly ball-milled $MgB_2$ was higher than that of C-doped $MgB_2$. The addition of diethylenetriamine was detrimental to Jc, although Tc was almost unchanged.
