심상훈련이 아시아 여자 운동선수의 특수한 생리학적 지표에 미치는 영향, 운동과학, 제8권 제2호, 283-298, 1999. 탁구, 조정, 그리고 펜싱을 하는 8명의 홍콩 여자 선수들은 개별화된 심상훈련 프로그램에 8개월동안 참가했다. 이 프로그램은 상담과 이미지 트레이닝을 포함하고 있다. 이 프로그램의 효과를 테스트하기 위해 Procomp Computer Biofeedback System과 생리학적 지수들이 사용되어졌다. 그리고 이 프로그램은 eletromyography(EMG) of forehead, 손가락의 skin conductance(SC), 손바닥 중앙의 skin temperature(ST), 손가락의 blood volume pressure(BVP), 그리고 심박수(HR)를 포함하고 있다. 이러한 결과는 실험이후에 가장 낮은 이마쪽 EMG나 HR(b/min) 값은 이완(p <.05)상태에서 실험 이전의 값보다 낮았다. 실험 이후 가장 높은 이마쪽 EMG와 HR(b/min)는 심상상태에서 실험이전의 값보다 더 높았다. 이완 상태에서의 가장 낮은 EMG와 심상 상태에서의 가장 높은 EMG사이에 실험이후 차이값은 33.6V로써 이는 실험전 8.22V보다 높은 것이었다. 이완상태에서의 가장 낮은 HR과 심상시 가장 높은 HR간의 실험후 차이값은 39.2b/min까지 기록되었는데, 이는 실험전의 24.2b/min보다 훨씬 높은 것이었다(p<.01). 이완 상태에서의 가장 낮은 SC와 심상시의 가장 높은 SC 사이의 실험후 차이간은 1.81V를 기록하였는데, 이는 실험전 0.41V보다 훨씬 높은 것이었다(p<.01). ST(C)와 BVP(%)는 같은 경향을 보였으나 그 차이는 통계적으로 유의한 값을 나타내지 않았다. 이러한 변화는 심상훈련 이후에 심리적 기능의 향상을 제시하였다. EMG, SC값과 HR값은 이완 상태에서 낮거나 일정하였고, 심상을 하고 있는 상황에서는 유의하게 증가를 하였는데 이것은 뇌를 자극하는 두 가지 변화를 나타내었다. EMG, SC 그리고 HR 이 세가지의 지표는 정신 훈련을 하는 동안 동시에 변하였으며, 특히 시청각 자극이 주어졌을 때는 더욱 많이 변하였다. 이 연구는 EMG, SC, 그리고 HR이 선수들의 정신상태 및 정신 훈련의 효과를 검증하는데 있어서 ST나 BVP보다 더욱 효과적이라는 것을 제시하여 주었다. The Effects of Mental Training on Specific Physiological Indices of Elite Asian Female Athletes. Exercise Science, 8(2): 283-298, 1999. Eight elite female athletes from Hong Kong in the sports of table tennis, rowing and fencing participated in an 8-month mental training program which was quite individualized. The program included consultation talk and relaxation-imagery training. A Procomp Computer Biofeedback System and 6 physiological indices were used to test the effects of the program, including electromyography (EMG) of forehead, skin conductance (SC) of finger, skin temperature (ST) of center of palm, blood volume pressure (BVP) of finger and heart rate (HR). The results showed Vat the lowest values of forehead EMG (v) and HR (b/min) during the post-experiment were lower than those of pre-experiment in the condition of relaxation (p<.05). The highest values of forehead EMG (v) and HR (b/min) of the post-experiment were higher than those of pre-experiment in the condition of imagery (p<.05). The difference value of post-experiment between the lowest EMG during relaxation and the highest EMG during imagery reached 33.6v, which was much higher than 8.22v of pre-experiment (p<.05). The difference value d post-experiment between the lowest HR during relaxation and the highest HR during imagery reached 39.2 b/min, which was much higher than 24.2 b/min of pre-experiment (p<.01). The difference value of post-experiment between the lowest SC during relaxation and the highest SC during imagery reached 1.81v, which was much higher than 0.41v of pre-experiment (p<.01). The ST (C) and BVP (%/) showed the same trends, but the difference did not reach statistical significance. These changes suggested the improvement of psychological skill after mental training. The values for EMG, SC and HR were lower and stable in the condition of relaxation and significantly increased in the condition of imagery, which indicated two-way changes of arousal in the brain. Three indices of EMG, SC and HR changed synchronously during mental training practice, especially when audio and visual stimuli were given. This study suggested that EMG, SC and HR were more effective than ST and BVP in terms of evaluating athletes' mental state and testing effects of mental training.

중국출신 결혼이주여성의 의사결정 공정성인식과 성역할태도가 부부관계만족도에 미치는 영향

Objectives: This study examined the effects of perceived equity in decision-making and gender role attitudes on marital satisfaction among Chinese-Han and Korean-Chinese migrant women. Methods: Data were drawn from the ‘National Survey on the Multi-Cultural Families in 2015’ and 1,350 Chinese migrant women born after 1979 under the implementation of “one child policy” were selected. Chi-squared test, t-test, and multiple regression analysis were performed for analysis. Results: There were differences between Chinese-Han and Korean-Chinese in marital satisfaction and perceived equity in decision-making. For Chinese-Han, ‘balanced group (perceived fairness in decision-making)’ showed higher marital satisfaction than ‘underbenefited group (husband is more dominant in decision-making)’. For Korean-Chinese, there was no significant difference between the groups. Conclusions: This study found how the perception of equity in decision-making would affect the quality of international marriage relationship. Especially, for Chinese-Han women, the equity plays an important role in marriage relationship.

Objectives: This study aimed to examine how mothers’ acculturation affected their children’s learning activity adaptation and how mothers’ educational involvement in home, public educational support and private tutoring mediated the association. Methods: Data were drawn from the 2016 Multicultural Adolescents Panel Study (MAPS). Among the total 1,635 multicultural adolescents, those in the 3rd year of middle school who had foreign mother and Korean father were selected. A frequency analysis, multiple regression analysis, logit regression analysis and hierarchical multiple regression were performed. Results: A direct effect and an indirect effect of foreign mothers’ acculturation on the adaptation of multicultural family adolescents’ learning activities were verified. Mothers’ Korean proficiency was directly associated with the adaptation of adolescents' learning activities, and that the mediating effect of mothers’ educational involvement in home and the relationship between mothers’ Korean proficiency and the adaptation of learning activities was found. Private tutoring mediated the relationship between the acculturative stress and the adaptation of adolescents' learning activities but had no direct effect of acculturative stress on the adaptation of adolescents learning activities. Conclusions: The results imply that although foreign mothers’ insufficient Korean proficiency has a negative effect on adolescents’ adaptation of learning activities, foreign mothers’ educational involvement in home and private tutoring can improve multicultural family adolescents’ adaptation of learning activities.

본 연구는 공급사슬 재무 메커니즘의 한 형태, 즉 한국 정부에 의해 촉진된 대·중소기업 간의 협력 추진 전략이 운전 자본 개선의 측면에서 (특히 중소기업에 대해) 효과가 있는지를, 대기업 공급자들로부터 직접 수집된 자료를 통하여 분석하였다. 기업 고정 효과 모형을 이용하여 얻은 실증적인 분석 결과는, 독립 기업에 비해, 대기업의 공급자가 기업의 운전 자본 조건을, 운전자본비율, 또는 현금화 사이클 양 측면에서 모두 개선하는 것을 나타내었다. In this paper, we examine whether a special form of SCF mechanism, the one promoted by Korean government through its large firms/SMEs cooperation promotion strategy, has real effects in terms of working capital improvement (especially for SMEs) using a hand collected sample of suppliers for large companies. After controling for potential endogeniety problems by utilizing firm fixed effect model, our empirical results show that compared to standalone firms, being supplier for large companies will improve firm``s working capital condition, either for working capital ratio or for Cash-to-Cash Cycle. And the improvement degree is both statistically and economically significant.

In this paper, we provide a comprehensive quantitative analysis of the dynamic competition/cooperation relationships among major ports in Korea and China. Utilizing time series models, the analysis shows that competition/cooperation equilibrium relationship does not stand in the Korea/China ports relationships in the long run, Korean ports generally have competitive relationships with their Chinese counterparties in the long-run. But in the short-run, the competition/cooperation relationships are mixed. While most Korean-Chinese port pairs have complementary relationship in the short-run, there are a non-trivial proportion of cases in which they react competitively.

White light emitting diodes(LEDs) with good color rendering indices(CRI) and high luminous efficiencies by the encapsulation of mixed and double-deck phosphors

Shang-Hui Yang,Jian-Shian Lin,Fuh-Shyang Juang,Ding-Chin Chou,Ming-Hua Chung,Chen-Ming Chen,Lung-Chang Liu 한국물리학회 2013 Current Applied Physics Vol.13 No.5

In this paper, white light emitting diodes (LEDs) with good color rendering indices (CRI) and high luminous efficiencies have been fabricated by the encapsulation of mixed and double-deck phosphors. Experimental results revealed that white LEDs with the encapsulation of double-deck phosphors exhibited better CRI and higher luminous efficiencies than those with the encapsulation of mixed phosphors because no secondary excitation took place. The hue, CRI, and luminous efficiencies of white LEDs with double-deck phosphors under 200 mA were CIEx,y =(0.357, 0.348), 90, and 62.3 lm/W,respectively while the hue, CRI, and luminous efficiencies of white LEDs with mixed phosphors under 200 mA were CIEx,y = (0.366, 0.354), 89, and 56.5 lm/W, respectively.
