일반적으로 혼자서 보내는 시간이 많을수록 외로움 수준이 높은 경향이 나타난다. 그러나 홀로 있을 때, 즉 사회적으로 고립되었을 때 외로움을 경험하는지 여부는 사람마다 다르다. 본 연구에서는 홀로 많은 시간을 보내는 사람 중, 누가 외로움을 경험하는지를 예측하는 요인으로 권력감(sense of power)의 역할을 알아보았다. 연구 1은 대규모 설문 조사 연구 자료를 이용하여 사회적 시간이 적은 사람들의 외로움을 예측하는 요인을 알아보았다. 판별분석 결과, 권력감이 사회적 활동 시간이 적은 사람들을 높은 외로움과 낮은 외로움 집단으로 판별하는 요인임을 검증하였다. 연구 2는 실험을 통해 권력감의 수준을 조작하여 높은 권력감과 낮은 권력감 집단으로 나누었다. 이후 홀로 있음을 점화한 뒤, 외로움과 소속감 상실의 여부가 권력감 조건에 따라 달라지는지 분석하였다. 그 결과 권력감이 높으면 사회적 외로움을 적게 경험하고 소속감 상실이 완충되는 인과관계를 확인하였다. 현대 사회는 일인 가정이 많아지고 코로나로 인해 사회적 만남이 제한됨으로써 외로움에 취약한 환경에 처한 개인이 전례 없이 많다. 본 연구는 이러한 현 상황에서 외로움 완화의 요인으로써 상황의 변화보다는 개인의 내적 심리적 측면에 주목하였다는 점에서 의의를 지닌다.

Background: This study was conducted to examine the effect of application of trampolin training elderly women by position sense of knee joint and balance. Methods: Ten subjects with elderly women were randomly assigned to trampolin training group (n=5) or control group (n=5). Experimental group received for 15 minutes three times during 4 weeks. Outcomes was made using One-Leg Stance Test, Time Up and Go Test and position sense of knee joint. Assessment was before training and one week, two week, three week after training. Results: Applied to the trampolin training group showed significant differences in all tests and for the interaction between time and group (p<.05). Conclusions: Those results indicate that trampolin training is effective in elderly women to promoting a position sense of knee joint and balance ability.

This paper describes the development of 5.15ns 32kb asynchronous CMOS SRAM using 0.6.mu.m CMOS technology. The proposed high speed embedded SRAM is realized with optimized control circuit and sense amplifier at a power supply of 3V. Using proposed control circuit, the delay time from address input to wordline 'on' is reduced by 33% and mismatch-insensitive sense amplifier can sense a small difference of bit-line voltage fast and stably.

Purpose: This study was conducted to compare pain, sense, bleeding, and hematoma that patients feel depending on the process of eliminating air of pressure band that was applied to patients after percutaneous coronary intervention (PCI) through radial artery. Methods: It was a nonequivalent control group pretestposttest design to compare pain, sense, bleeding, and hematoma by amount and time of eliminating air of pressure band after PCI through radial artery. Results: On arrival at Coronary Care Unit, meaningful difference didn't exist between pain and sense, however, after two hours of starting eliminating air, the points of pain and sense were meaningfully low (p<.001). Also, there was meaningful difference in reciprocal action between group and time (p<.001). Conclusion: After PCI, the conclusion showed there is positive effect in decreasing wrist pain and sense without any influence of bleeding by eliminating air from patients' pressure bands.

When grasping a movable object or making an object move, humans feel kinesthetic sense. The kinesthetic sense is the human sense that the human feels in response to the motion acted on him. The objective of the paper is to transform the kinesthetic sense associated with the human arm into the quantified data that are useful from the engineering viewpoint. A 2-dimensional motion generator composed of two linear motors was developed to provide various motion patterns. It can change its stiffness and damping values on the real-time basis by properly regulating the force generated by the linear motors. Based on Taguchi method, the most dominant factors to affect the kinesthetic sense were investigated. Also, a reference function adequate to quantify the kinesthetic sense was found. Based on this function, the effects of changes in stiffness and damping on the kinesthetic sense were investigated. Various tests show that the damping is a more dominant factor than the stiffness in forming the kinesthetic sense.

DRAM에서 셀 파라메터들의 확률 분포를 고려하여 데이터 보유 시간에 대한 분포 특성을 계산하였다. 셀 파라메터와 셀 내부 전압의 과도 특성으로부터 데이터 보유 시간의 식을 유도하였다. 접합 공핍 영역에서 발생하는 누설 전류의 분포 특성은 재결합 트랩의 에너지 분포로, 셀 캐패시턴스 분포 특성은 유전체 성장에서 표면 반응 에너지의 분포 특성으로, 그리고 sense amplifer의 감도를 각각의 독립적인 확률 변수로 보고, monte carlo 시뮬레이션을 이용하여, 셀 파라메터 값들의 확률적 분포와, DRAM 셀들의 데이터 보유 시간에 대하여cumulative failure bit의 분포함수를 계산하였다 특히 sense amplifier의 감도 특성이 데이터 보유 시간 분포의 tail bit에 상당히 영향을 미침을 보였다.

In this paper, a multi-time programmable (MTP) cell based on a $0.18{\mu}m$ bipolar-CMOS-DMOS backbone process that can be written into by using dual pumping voltages - VPP (boosted voltage) and VNN (negative voltage) - is used to design MTP memories without high voltage devices. The used MTP cell consists of a control gate (CG) capacitor, a TG_SENSE transistor, and a select transistor. To reduce the MTP cell size, the tunnel gate (TG) oxide and sense transistor are merged into a single TG_SENSE transistor; only two p-wells are used - one for the TG_SENSE and sense transistors and the other for the CG capacitor; moreover, only one deep n-well is used for the 256-bit MTP cell array. In addition, a three-stage voltage level translator, a VNN charge pump, and a VNN precharge circuit are newly proposed to secure the reliability of 5 V devices. Also, a dual memory structure, which is separated into a designer memory area of $1row{\times}64columns$ and a user memory area of $3rows{\times}64columns$, is newly proposed in this paper.

A novel self-reference sense amplifier with parallel reading during writing operation is proposed. Read access time is improved compared to conventional self-reference scheme with fast operation speed by reducing operation steps to 1 for read operation cycle using parallel reading scheme, while large sense margin competitive to conventional destructive scheme is obtained by using self-reference scheme. The simulation was performed using standard $0.18{\mu}m$ CMOS process. The proposed self-reference sense amplifier improved not only the operation speed of less than 20 ns which is comparable to non-destructive sense amplifier, but also sense margin over 150 mV which is larger than conventional sensing schemes. The proposed scheme is expected to be very helpful for engineers for developing MRAM technology.

In this paper, we analyzed the effect of a training system for improving equilibrium sense. This training system consists of an unstable platform, a force plate, a computer, and training programs. Using the system with training programs, we performed various experiments to train the equilibrium sense of fifteen subjects. To evaluate the effect of the training system, we measured the time a subject maintains a focus, the moving time to the target, and the absolute deviation of the trace. We analyzed these parameters obtained before and after the training using paired-samples T-test. The results showed that the subjects experienced a distinctive enhancement of their equilibrium senses through the training using our system.

This study is aimed to identify the expression and the sense of time in contemporary architectural space. And to classify the system and elements of Zeitlichkeit in the contemporary architectural design. The concept of time can be divided into two meaningful perceptions. Those are the concept of realistic time and the concept of subjective time. These tendencies of theories of architectural space has borrowed from innovations in the sciences, and the whole idea of space-time within art and architecture. Those notions developed through the researches of Bauhaus, Postmodernism, Landscape architecture, Digital Architecture and so forth. The result of this study is that the concepts of time are one of the most important strategies of architectural design and have the various languages which there was not in the past. At the point of the transformation in contemporary architecture, the The concepts of space-time are classified into those from the orders of form and space, from dynamic of the image in the dissolution of architectural form, from traces and steps of movement in dynamic form, and from the systems of commands in the digital softwares. As such, Zeitlichkeit in contemporary architecture means that the architecture moves from the construction of the sensual design elements into Art of life through events and contents which human can experience and recognize. These theories and researches reveal that contemporary architectural movements insert the meaningful stories into architectural space through programs and diagrams.
