This study examined preschoolers' compliance and noncompliance as it related to maternal behavior, child gender and age, and social context. The subjects were 213 preschool children in Seoul. Data were collected via questionnaires reported by mothers and teachers. The results of correlation analysis and a series of repeated measures ANOVA revealed that mothers' coercive parenting was associated with lower committed compliance and ignorant noncompliance. It was also found that the 5-year-olds studies showed higher committed compliance in moral situations whereas the 6-year-olds showed higher situational compliance in conventional situations. Noncompliance was more common among the 5-year-olds than the 6-year-olds. It was also found that girls exhibited higher compliance than boys in both moral and conventional contexts. The results were discussed in terms of a developmental perspective.

화이트 밸런스를 유지해야 하는 이유는 입력 이미지의 컬러 밸런스와 동질의 화질 유지를 위하거나, 혹은 이미지를 개선할 때 화질 균일 성을 유지하기 위함이다. 그러나 기존 컬러 개선 방식들은 화이트 밸런스 보존에 관계없이 컬러 개선이 이루어지기 때문에 컬러 개선 전과 후의 화이트 밸런스가 다르게 나타난다. 이 논문에서는 색 순응 변환을 이용하여 화이트 밸런스를 보존하면서 자연스러운 컬러 이미지 개선 및 컬러 측정 알고리즘을 제안한다. 그 결과는 제안된 알고리즘은 Color Naturalness Index 와 Color Colorful Index 라고 풀리는 객관적 방법뿐만 아니라 주관적인 방법 에서도 개선됨을 확인하였다. 알고리즘의 복잡도는 낮으므로 현실 어플리케이션에서도 유용하게 이용될 것이다.

Control of a biped robot which has compliant ankle joints is dealt in this paper. Simulated version of a human ankle joint is built using springs and mechanical constraints, which gives a flexibility of joint and compliance against the touching ground. The biped robot with compliant ankle joints proposed here gives a good contact between its sole and the ground and makes foot landing soft. As a result, installing force sensors for measuring the center of gravity of the biped becomes easier. A motor to drive an ankle joint is not needed which makes legs light. However, the control problem becomes more difficult because the torque of the ankle joint to put the biped in a desired walking gait cannot be provided from the compliant ankle joint. To solve this problem, we proposed a dynamic gait modification method by adjusting the position of a hip joint. Simulation results for the mathematical model of the SD-2 biped in the Ohio State University are given to show the validity of the proposed controller.

In this paper, compliant motion control of a manipualator in manipulator is proposed by using the self-tuning adaptive controller. Compliant motion is needed in order to applicated to complicated and accurate fields such as assembly operation in which several parts are matched. For a control method of compliant motion hybrid control is used so forces and position control are proposed selectively through a closed feedback loop. By contacting with environment, the uncertainties higher. Self-tuning controller which adapts to variable dynamic response is applied to compliant motion control in order to satisfy the desired operation. The applicability of the suggested algorithm was confined by simulation of the contour tracking task of four joint manipulator.

This paper presents the attitude control of the double inverted pendulum with compliant joint. The biped robot with compliant ankle joint instead of a motor have a good contact between it's sole and ground in the uneven ground. The compliant ankle joint proposed here is composed of springs and mechanical constraint. The lower link is hinged on the plate to free for rotation in the vertical plate. The upper link is connected to the lower link through a DC motor. The DC motor is used to control the posture of the pendulum by adjusting the position of the upper link. The algorithm for controlling a proposed inverted pendulum is nonlinear feedback controller. Simulation with mathematical model are conducted to show the validity of the proposed controller.

Treatment-resistant schizophrenia (TRS) has been defined as the persistence of positive symptoms despite two or more trials of antipsychotic medication of adequate dose and duration. TRS is a serious clinical problem and occurs in approximately 30% of patients with schizophrenia. It is important that patients who do not adequately respond to antipsychotics be reevaluated to exclude or address causes other than non-responsiveness to medication, that is, the possibility of pseudo-resistance. In particular, non-adherence to oral antipsychotic treatment should be monitored to rule out pseudo-resistant cases of TRS. Moreover, patients with TRS who take their medication as required may have subtherapeutic antipsychotic plasma levels, secondary to pharmacokinetic factors. In this paper, we review the concept and exclusion of pseudo-resistance, especially owing to non-adherence or pharmacokinetic factors, and present methods to enhance drug adherence.

In general, control performance of the active control system is superior to that of the passive control devices. However, the active system require a large amount of external energy to operate the actuators. Semi-active control systems maintain the reliability of the passive control systems while taking advantage of the adjustability of the active control system. In this research, a semi-active orificed fluid damper having the capacity of about 2 tons was designed and fabricated. It is a two-stage damper with normally open solenoid valve. A series of tests was performed to grasp its performance characteristics. It was also applied to a 6-story steel structure subjected to random and seismic excitations for the confirmation of its validity on structural vibration absorption.

본 연구는 경관선호에 관한 평가방법을 서술적으로 구명하면서 기존의 경관선호에 관한 평가방법이 자연적 요소를 많이 포함한 경관의 평가출 정착히 하는데 따르는 문제점을 제시하고 경관의 우연적 국면에 따라 경관선호의 우연성(Contingency in Landscape Preference)을 개관하면서 경관평가의 우연성(Contingency in Landscape Evaluation)에 의한 우연적 경관평가방법(Contingent Approach in Landscape Evaluation)의 가능성을 시사했다. 최근까지의 경관평가방법을 크게 분류하면 총체적(Universal) 접근방법, 개성적(Idiosyncratic) 접근방법, 조화적(Contrastic) 접근방법 등으로 나눌 수 있다. 그런데 경관성에서의 우연성을 강조함 으로써, 앞의 세방법만을 가지고서는 경관의 실체 파악이 어렵기 때문에 새로운 방법이 강구되어야 한다. 이의 한 대안으로 경관선호에 대한 평가를 우연적 접근방법으로 해결함으로써 평가영역과 평가요소를 확장시킬 수 있다. 따라서 수학적 매트릭스가 가능하다는 시사를 본 연구에서 구시하면서 새로운 평가방법으로 우연적 경관평가방법을 제시했다. 우연적 경관평가방법은 우연적 경관성에 의한 심미성을 고려하여 종합적으로 분석할 수 있으나 우연적 영역을 의도적으로 설정하지 않는 한 현실적으로 재정적 흑은 시간적 제약성을 지니고 있다. 그러나, 경관선호의 정도에 관한 평가보다는 경관의 본질을 구성하는 모든 요소를 고려한 평가가 경관선호평가에 대한 종합성을 반영할 수 있다. 경관평가의 모호성에도 불구하고 경관의 본질은 우연성에 의존한다고 본다면 우연적 경관평가방법은 크게 무리가 없다. 결국 경관은 생명성을 지니고 있기 때문에 현상으로만 볼 것이 아니라 동시적이면서 산재적 이며 상황적 다양성으로 간주해야 하며 고러란 관점을 강조한 것이 우연적 경관선호 및 경관평가에 대한 접근이라 할 수 있다.도 나타났다. 직업간의 유의성은 학생과 타 직업간에 나타났다. 직업간의 유의성은 학생과 타 직업간에 현격하게 나타났으나, 개인차를 나타내는 속성적 변수는 상호보완적인 변수기능을 수행하고 있기 때문에 다양한 행동의 설명력있는 이유로 볼 수 없다.때로는 민담에서도 풍수가 주제가 되는 경우가 있고, 일반적으로는 역사적 사실이나 인물을 통하여 취락민이지녀온 자연요소에 대한 인식관 또는 그러한 생활에서 나타나는 윤리관 등이 암암리에 표현되기도 한다. 민담을 통하여 우리는 주민들 의식 속에 남아있는 취락의 중요한 요소나 장소들을 찾아볼수 있고 더불어 이들을 중심으로 이루어 졌을지도 모를 생활모습들을 생각해볼 수 있다. 이러한 것들은 $\ulcorner$순응$\lrcorner$의 다른 일면 또는 때에 따라서는 극히 의도적인 $\ulcorner$표현$\lrcorner$적인 한 면모 - 그 대표적인 경우로 정원을 구성하는데 개재된 인간의 의미는 무언가를 표현 또는 표출하고자 함에 있다는 점 -라 볼수도 있을, 예로써 성리학적 사고관념으로써 집과 정사 그리고 주변 경관을 자신의 내적본직 또는 윤리적 영역으로 삼아 묘사.표현.구체화 시켜가기도 한다. 최소한 동족부락의 한두 예들에서 그러한 $\ulcorner$표현$\lrcorner$적 의도에 의한 경관구성의 일면을 확인할수 있지만 엄밀히 생각하여 보면 이러한 예의 경우도 최락의 총체적인 외형은 마찬가지로 $\ulcorner$순응$\lrcorner$의 범위를 벗어나지 않는다. 그렇기 때문에도 $\ulcorner$순응$\lrcorner$과 $\ulcorner$표현$\lrcorner$의 성격과 형태를 외형상으로 더욱이 공간상에서는 뚜렷하게

Objectives: Nasal continuous positive airway pressure (nCPAP) is the treatment of choice and has been shown to reduce the frequency of nocturnal respiratory events, improve sleep architecture, and decrease daytime sleepiness in patients with obstructive sleep apnea syndrome (OSAS). However, little is known about the compliance of nCPAP treatment in Korea. Our objective was to look into the nCPAP compliance and examine the factors influencing it. Methods: We reviewed the records of one hundred and twenty consecutive patients with OSAS referred for nocturnal polysomnography with nCPAP pressure titration during the period of January 1995 through April 1999 to the Seoul National University Hospital. We performed a telephone interview and obtained data from eighty-three patients. Results: In sixty patients who had accepted nCPAP treatment, twenty-six patients (43.3%) were still using nCPAP device, while thirty-four patients (56.7%) stopped using it. Fifteen patients (25%) were using nCPAP device everyday. In thirty-four patients who discontinued nCPAP use, twenty-five patients (73.5%) did within the first three months, and thirty-one (91.2%) within the first year. Significant predictor of long-term nCPAP use was the presence of subjective daytime sleepiness before nCPAP application. Conclusions: Long-term compliance with nCPAP treatment appears to be associated with the presence of subjective daytime sleepiness before nCPAP application. Long-term compliance with nCPAP may be mostly predicted from the usage pattern within the first three months of use.

This study analyzed the impact of family firms and their characteristics on how they use debts to analyze the decision-making process of Korean family firms. For analysis, we classified the characteristics of family firms into three categories, through the influence of the relationship between the lack of funds and net debt issuance, which was confirmed as the 'packing order theory' of family firms. There was a total of 4,503 enterprises in the Korean Exchange (KRX). The period of analysis was 10 years, between 2004 and 2014. To summarize, Shyam-Sunder and Myers (1999) validated the packing order theory by presenting a model of family businesses that showed greater applicable to higher packing order theory than a model of non-family businesses. Moreover, the results also confirmed the application of the packing order theory by the family stronger corporate governance and ownership structure. The ownership and governance characteristics of the ruling family has also shown the applicability of higher packing order theory.
