행복은 인간이 추구하는 최고의 가치이자 선이다. 그러나 오늘날의 경영환경은 직원들에게 점점 더 많 은 자원을 요구하여 그들의 행복추구를 방해한다. 자원보존이론과 긍정정서의 구축 및 확장이론에 의하 면, 개인의 행복은 그들이 소유하고 있거나 획득할 수 있는 자원량에 비례하게 된다. 본 연구는 심리적 웰빙이라는 개념을 통해 조직 구성원의 행복을 살펴보고자 한다. 이 연구에서 저자는 먼저 심리적 웰빙의 정서적 측면과 자아실현적 측면을 구분한 다음, 목표 상황에 따라 이러한 측면이 어떻게 변화하는지 살펴 본다. 목표설정이론에 근거하여 목표달성을 위해 자기규제를 할 경우 이를 통해 자아실현적 측면의 심리 적 웰빙을 증진할 수 있지만, 동시에 상실되는 자원을 통해 정서적 웰빙이 침해될 수 있다. 목표가 불명확 할 경우 목표달성가능성이 줄어들어 개인은 회피적 자기규제를 통해 자원손실을 줄이게되고 이를 통해 정서적 웰빙을 보호하지만 자아실현적 웰빙은 감소할 수 있다. 본 논문은 또한 상사근접관리로 인한 강제 적 규제상황을 가정하여 조절효과를 확인하였다. 12개 조직의 데이터를 수집하여 통계적으로 검증하였다. 그 결과 목표의 난이도와 모호성은 직원의 자기조절 전략을 통해 심리적 웰빙을 변화시키며, 이러한 경향 은 상사근접관리에 의해 조절되는 것으로 나타났다. 그리고 심리적 웰빙의 이 두 가지 측면이 갖는 이론 적 및 실무적 시사점에 대해서도 논하였다.

Background: The hip muscle plays various roles. Several types of functional performance tests are used for the assessment of patients with various lower extremity injuries. Hip muscle functions are important to test the performance of maintaining the spine, pelvic, and leg during bridging exercise. We designed a novel functional performance test tool, which we named close kinetic chain dynamic lower extremity stability (CKCLE) test to assess hip muscle functions. Objects: The purpose of this study was to determine the relationship between CKCLE test and hip extensor, external rotator, and abductor strengths. Methods: Twenty-two subjects were recruited in the present study (13 males and 9 females). The hip extensor, external rotator, and abductor muscle strengths were measured using a Smart KEMA strength sensor. When the examiner said “Go”, the subject performed the CKCLE test by moving one leg from the floor and touching the opposite knee and then return to the floor while maintaining the bridging position. The subjects attempted as many “touches” as possible in the allotted time (20 seconds) during the maximal tests. The correlation between the hip muscle (extensor, external rotator, and abductor) strength of the supporting leg and the number of CKCLE tests performed in 20 seconds was determined using the Pearson correlation. Results: Hip extensor (r = 0.626, p < 0.05), hip external rotator (r = 0.616, p < 0.05), and hip abductor muscle strengths (r = 0.475, p < 0.05) positively correlated with the number of CKCLE tests performed. Conclusion: We designed a CKCLE test and found that performance in the test correlated with hip extensor, external rotator, and abductor muscle strengths. The result suggests that the CKCLE test can be applied as a performance test to assess the functions of the hip extensor, external rotator, and hip abductor muscles.

본 연구는 항해사가 근접상황에서 심리적 충돌의 두려움으로 당황하여 규정된 충돌 회피조치를 수행하지 못하는 인적오류 상황을 연구하였다. 연구 목적은 선박 간 근접상황에서 항해사의 인적특성 요인인 승선경력, 면허등급, 연령요인이 충돌위험도에 미치는 영향을 규명하는 것이다. 본선과 상대선박 간 네 가지 대표적인 근접상황의 충돌침로에서 항해사가 지각한 충돌위험도 값을 측정, 정량화된 데이터를 얻기 위하여 시뮬레이터를 이용하여 충돌위험도 측정실험을 설계하고 두 척의 선박이 거리 2.5해리에서 충돌상황까지 상호 10 노트의 속도로 접근할 때 본선의 30명의 항해사의 심장박동변이를 측정하여 항해사가 지각한 충돌위험도 측정데이터를 확보하였다. 측정 값에 대한 다중회귀분석 결과 항해사의 승선경력과 면허등급 요인은 충돌위험도에 부(-)의 영향을 미쳤고, 연령은 영향을 미치지 않았다. t-검정 결과 승선경력≤4년인 항해사는 승선경력≥5년인 항해사 보다 충돌위험도 값이 유의미하게 높았고 면허등급 요인은 4 ~ 6급 그룹이 2 ~ 3급 그룹보다 충돌위험도 값이 유의미하게 높게 나타났다. 본 연구결과는 충돌위험경보시스템 개발에 적용될 수 있을 것이다.

PURPOSES : The purpose of this study is to estimate the reduction of traffic noise in a double-layered specific porous pavement based on the traffic speed variation. METHODS : The close-proximity method was used in noise measurement, and the running speed was measured at 10 km/h and from 50 to 80 km/h. RESULTS : From the quantitative analysis, it was found that the double-layered porous pavement reduced by 9.4 dB (A) on the average and 9.16 dB (A) at a 95% confidence level. CONCLUSIONS : The use of porous pavements have been recommended to minimize traffic noise. In this study, it is quantitatively demonstrated that the double-layered porous pavement can reduce the traffic noise by more than 9.0 dB(A).

People want to watch a sports game which cannot anticipate the result until the end of the game. Sometimes, however, excessive tension of contest lowers the interest of audience. Vast amount of existing researches have focused on finding explanation about what makes a difference of the preference level of suspense among sports fans and where is the optimal level of suspense. We apply Expected Utility Theory and Prospect theory to illustrate the expected utility of sports spectators. According to our findings, if someone someone who is satisfied more when the cheering team wins, he or she may prefer lopsided match than close match. And fans who support winning team, which means team which wins often, prefer lopsided match to close match because they forecast their team will win more than fans who support losing team, which means team which loses often. We manipulate the level of satisfaction when the cheering team wins (S) and subjective forecasted probability of win before the game (Q) of respondents and measure the utility of them toward difference game aspect (P) to verify our hypothesis. This study was carried out to investigate how the satisfaction of sports spectators will change according to the change of the game aspect. In particular, research model was set up using the Expected Utility Theory and Prospect Theory of economics. The use of economics models to explain sports consumer behavior is different from that of previous studies, and consumers' prior expectations can affect the current game viewing based on Prospect Theory is another contribution of this research.

At the end of the twentieth century the decline of the domestic knitting craft was of paramount concern to the yarn companies and retailers that served this market sector. As demand reduced in the UK so did the number of specialist retailers. This was as detrimental to the yarn companies as it was to the craft. Research undertaken in 1999 by the author suggests that it is probably true to say that the knitting craft was at that point in time at its lowest point of popularity throughout the entire twentieth century. Throughout the twentieth century in the UK the popularity of crafts as domestic leisure pursuits fluctuated. Increased interest is reported to be primarily related to economic recession, where necessity is identified as being the greatest motivation for craft engagement; and craft engagement declines when the economy is more buoyant. There is evidence to support claims that the popularity of crafts in general experienced rise and fall throughout the 20th century correlating with times of austerity during economic downturns, thus suggesting that crafts were still largely taken up then as a necessity which could be contested. This paper reports briefly on the reasons behind the rise and fall of the hand knitting craft’s popularity throughout the last century in the UK before focusing on the latter decades in order to expose the factors related to the more serious decline of the craft in the 1990s. It discloses the perceptions of the craft at the end of the century and provides the foundation for the next stage of the research project which will involve an investigation of the craft in the early decades of the twentieth-first century. The paper draws predominantly on company and trade reports such as Keynote and Mintel and on previously unpublished survey materials from the late 1990s that were designed to explore the state of the hand knit craft at the close of the twentieth century.

This study attempts to investigate the impact of pollution by VOCs at schools located around Shihwa national industrial complex. Schools around the Shihwa national industrial complex were divided into two categories based on location, with five schools located near the industrial complex and five schools located near housing development. Samples of the indoor air and the outdoor air were collected from each classified school and analyzed to evaluate the impact of the industrial complex on each school through a comparison and to find the correlation between them. In combination with this, this study attempted to conduct comparative evaluations of the schools in which there might be relatively higher indoor air pollution since new construction and extension or remodelling had recently been carried out with other schools. The samples collected from 10 places in total were analyzed, using GC/MS. TVOCs, and individual component of VOCs, were detected in the schools near shihwa national industrial complex at higher levels than in the schools nearby housing development. TVOCs were detected at the schools in the industrial complex st levels of 166.5 μg/m3, that is, about 1.5 times higher than the level detected at the schools outside the industrial complex. TVOCs were found in the indoor air of the schools that had been extended or remodelled less than 3 years ago at levels of 188.8 μg/m3, while in schools where more than 3 years had passed since extention or remodelling they were found at levels of 97.5 μg/m3, meaning they were about 1.9 times higher in schools in the first 3 years.

Close binary stars are so close that one component has an effect on the evolution of the other. But how do they form and evolve? This is an unsolved problem. One speculation is that the binary is a part of a hierarchical triple and its orbit shrinks due to interaction with the third component. Therefore, searching for and investigating tertiary components, especially close-in ones, in close binary stars are important for understanding their origin, as well as to test theories of star formation and stellar dynamical interaction.

Due to the lack of an accretion disk in a polar (magnetic cataclysmic variable, MCV), the material transferred from the secondary is directly accreted onto the white dwarf, forming an accretion stream and a hot spot on the white-dwarf component. During the eclipses, different light components can be isolated. Therefore, the monitoring of eclipsing polars could provide valuable information on several modern astrophysical problems, e.g., CVs as planetary hosting stars, mass transfer and mass accretion in CVs, and the magnetic activity of the most rapidly rotating cool dwarfs. In the past five years, we have monitored about 10 eclipsing polars (e.g., DP Leo and HU Aqr) using several 2-m class telescopes and about 100 eclipse profiles were obtained. In this paper, we will introduce the progress of our research group at YNOs. The first direct evidence of variable mass transfer in a CV is obtained and we show that it is the dark-spot activity that causes the mass transfer in CVs. Magnetic activity cycles of the cool secondary were detected and we show that the variable mass transfer is not caused by magnetic activity cycles. These results will shed light on the structure and evolution of close binary stars (e.g., CVs and Algols).

AC PDP의 Vt 폐곡선 측정에 의하여 개방형 유전체 구조에서 방전 전압과 내부 벽전압 등의 방전 특성이 종래의 구조와 비교되어 조사되었다. 개방형 유전체 구조는 상판 전극사이의 유전체를 없애서 유지 전극간의 방전이 더욱 쉽게 발생하도록 하는 구조이다. 개방형 유전체 구조에서 상판의 두 전극인 주사와 유지전극 간 방전 개시전압이 종래의 구조와 다르기 때문에 종래의 기입파형을 포함한 초기화 파형도 수정되어져야 한다. Vt 폐곡선 분석에 기초하여 개방형 유전체 구조에 적합한 수정된 구동파형이 제안되었고 42인치 AC PDP에서 실험되었다.
