This study was carried out to obtain a basic data on the production of the Nd-Fe-B system rare earth anisotropic bonded magnet by R-D & HDDR process. The reduction reaction of Nd$_2$O$_3$by metallic Ca and the diffusion reaction of Nd into Fe-B alloy powder were investigated for the production the Nd-Fe-B alloy powder. We concluded that a proper quantity of metallic Ca was about 1.3 times of theoretical equivalent from the yields of Nd and B after the R-D reaction at 100$0^{\circ}C$ for 1h. In the XRD analysis the diffusion reaction of Nd into the center of Fe-B alloy powder for the completed homogenization was required through about 45min at 110$0^{\circ}C$ for the R-D reaction, and also the maximum efficiency on the yield of Nd was obtained with such a condition. Residual Ca and oxygen contents of the final powder sample after washing were detected in 0.17wt% and 0.42wt% by ICP and oxygen analyzer, respectively.

Dong-a Ilbo tried to assume leadership of opinion in preceding the movement against the trusteeship as a mouthpiece for the Han-Min Party. Dong-a Ilbo was to try to promote the atmosphere of anti-trusteeship=anti-communism=anti-Soviet Union, distorting the decision of a conference of three foreign affairs ministers in Moscow. It was not an incorrect report, but the false report. As a result, the formula of an anti-trusteeship=anti-Soviet Union=anti-communism=patriotism, and a pro-trusteeship=pro-Soviet Union=pro-Communism=traitor was formed. And the important problems of land reform and pro-Japanese‘ clearance were missing. Historically, political newspapers had appeared in the periods of very important political change. Political newspapers played a role as mouthpiece for political party or group. Dong-a Ilbo was such a political newspaper. It was that Dong-a Ilbo tried to change the social atmosphere in preceding the movement against the trusteeship as a mouthpiece for the Han-Min Party. And history was distorted.

The purpose of this study is to examine whether the social capital supported by social enterprises play a role in ensuring self-sustaining and sustainable growth, and to examine whether the mediating effect of social capital have a central effect on social performance. The results of this study are as follows: Innovation and orientation-to-social-value of social entrepreneurship have positive effects on structural capital, and positive influence on cognitive capital and relational capital, but innovation only has no effect. In addition, social entrepreneurship is partially mediated by structural capital. In the mediating effect between social entrepreneurship and cognitive capital, only the risk-taking and the orientation-to-social-value have a partial mediation effect on cognitive capital. However, only the initiative of relational capital was found to have a full mediating effect. And social capital has a positive effect on social performance as a whole. In conclusion, considering that the realization of economic purpose and other social purpose of social enterprises will help to develop and create jobs in the local community, and that they are engaged in business activities in a poor management environment, to provide policy support for inducing high value-added industries through industry-specific collaborations.

많은 소비자들이 가치지향적인 의사결정을 할 때 제품의 품질을 매우 중요한 요소로 생각하며, 제품구매시 불완전한 정보 상황에서 빈번히 제품품질의 지표로서 가격을 이용한다고 한다(Peterson & Wilson. 1985). 이와 관련하여 시장에서의 실제 가격과 객관적 품질과의 관계를 분석하여 소비자의 효율성을 파악한 연구가 각국에서 이루어져 왔으나, 패션제품에 관한 가격과 객관적 품질과의 관계에 관한 연구는 국내 외적으로 매우 미흡한 실정이다. 따라서 본 연구의 목적은 1990년대 한국과 미국 패션시장의 가격과 객관적 품질간의 상관관계를 비교 분석함으로써 양국 패션제품의 품질수준을 비교해 보 는데 있다. 본 연구의 결과를 통해 가격이 제품품질의 지표가 될 수 있는가를 파악할 수 있을 것이다. 이를 위해 본 연구에서는 다음과 같은 연구문제를 설정하였다. 첫째, 한국과 미국 패션제품 시장의 가격과 품질의 상관관계는 전체적으로 어떠한 차이가 있는가\ulcorner 둘째, 한국과 미국 패션제품의 가격과 객관 적 품질의 상관관계가 패션산업범주에 따라 어떠한 차이가 있는가\ulcorner 마지막으로, 본 연구의 결과와 같은 제품의 품질에 대한 정보탐색으로부터 얻을 수 있는 한국과 미국 소비자의 구매이득은 어느 정도인가\ulcorner 본 연구를 위한 내용분석에 이용된 자료는 양국의 소비자의 권익보호를 위한 중립적 정보원에서 발간하고 있는, 한국의 <소비자 시대>와 미국의 에 개 재 된 1990년부터 1999년까지 의 상품비교테스트 정보중에서 패션제품군에 관련된 자료를 토대로 하였다. 수집된 자료는 한국의 36개 패션제품군, 470개 제품과, 미국의 40개 패션제품군. 692개의 패션 제품이었으며, 패션산업범주는 여성복, 남성복, 유니 섹스 의류, 스포츠 의류, 유.아동복, 언더웨어. 잡화. 제화류, 침장류, 섬유직물, 화장품. 학생복 등 11 가지 산업범주로 분류하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 한국과 미국 패션제품의 지난 십년간의 가격 과 품질의 상관관계는 매우 약한 정(+)의 상관을 가지고 있었다. 한국패션제품의 전체 서열상관계수의 평균은 0.091이었고, 미국의 상관계수 평균은 0.192였 다. 상관계수의 수치만으로 볼 때 한국보다는 미국 패션제품의 가격과 품질간의 상관관계가 조금 높게 나타났으나, 양국간 통계적인 차이는 없었다. 또한, 한국 패션제품의 경우에는 제품군의 가격대별 상관관계를 살펴보았는데, 그 결과 1만원 미만의 저가 제품군과 330만원이상의 고가의 제품군의 경우 부(-)의 상관계수를 나타냈다. 둘째. 1990년대 한국과 미국 패션시장의 가격과 품질간의 상관계수의 범위는 제품군별. 산업범주별 로 상이한 분포를 보이고 있었다. 패션제품군별로 보 면, 한국의 경우는 가장 높은 '여행용가방(r = 0.707)' 에서 가장 낮은 '자외선 차단화장품(r = -0.58)'까지, 그리고 미국 패션제품군의 상관계수의 범위는 '팬티 스타킹'의 0.820에서 '남성용 런닝슈즈'의 -0.472까지의 분포를 나타냈다. 마지막으로, 제품의 가격과 품질에 대한 정보를 소비자가 알 경우 얻을 수 있는 소비자의 구매이득 을 추산한 결과 패션제품시장에서 완전한 품질정보를 가지고 있다고 가정한 '현명한 사람'은, 최고가격의 제품만을 구입한다고 가정한 '부유한 사람들'의 구입방식에 비해 최고 좋은 품질의 상품을 총 지불액의 비율로 보아, 한국의 소비자는 약 50% 정도를, 미국의 소비자는 약 91%나 되는 액수를 절약하여 구매할 수 있는 것으로 나타났다. 이상의 본 연구의 결과를 종합하여 볼 때 한국과 미국 모두 제품군별, 그리고 산업범주별로 상관관계가 차이를 보이고 있어, 양국의 소비자들이 패션제품 의 품질을 평가함에 있어 오로지 가격에 대한 정보만을 이용하는 것은 위험하고 비합리적인 구매의사 결정이라고 볼 수 있다. 따라서 소비자가 좀 더 합리적인 구매의사결정을 하여 재정적 손실을 막기 위해서는 가격과 품질에 관한 신뢰있는 정보의 탐색이 반드시 필요하다고 본다.

This study aim to analyze the effect of the technology support program satisfaction on below ICT Small and Medium-sized Enterprises(below SMEs)'s technological performance. For the empirical analysis, we used the data collected from ICT SMEs technology support program conducted by ETRI - a government funded research institute. Among 153 beneficiaries, 141 companies participated in the survey and we used 102 of them for our analysis. Then, we used the mediation regression analysis. In our research model, we set the program satisfaction as a independent variable, the amount of technology support as a mediator variable and the technological performance as a dependent variable. Results show that program satisfaction has positive and significant impact on both amount of technology support and technological performance and amount of technology support has complete mediation effect on product innovation while has partial mediation effect on technological innovation. Our findings imply that more ICT SMEs technology support programs that satisfying the beneficiaries should be developed until the rest of ICT SMEs could become the hidden champions.

One of the most important factor of esthetic prosthesis is the color of the teeth. Zirconia is produced in the process of design, milling, coloring, drying, and sintering. The effect of the drying degree of zirconia colorant on the color tone is examined. For the experiment, a total of 45 zirconia specimens(15 for each) were fabricated by using cad/cam system. The zirconia specimens(L block(LAZOR), Z block(Zircos-E block posterior), A block(AlphaZ)) were then subjected to zirconia sintering in accordance with the manufacturer's instructions, using a chemical coloring agent to Non-drying(0sec), intermediate (10sec), and completely dried (10min) temperature holding times. The color tone was measured using a spectrophotometer. The results were analyzed with a One-way analysis of variance and the Tukey post-hoc test (${\alpha}=.05$) The $L^*$ values of L, A specimens, $a^*$ values of A specimens, and $b^*$ values of Z specimens were not statistically different according to the degree of drying (p>0.05), While the $L^*$ value of Z specimen, $a^*$ value of L, Z specimen, $b^*$ values of L, A specimens were statistically different according to the degree of drying(p <0.05). In conclusion, the drying of zirconia colourants improves zirconia brightness and increases the optical properties of the enamel.

Quantitative HPLC analysis for the determination of in herbal liquid preparations was improved from the general test method besides the Korean Pharmacopeia. Good chromatographic separation of samples containing parabens, interferences, and other pharmaceutical excipients was effectively achieved by using acetonitrile water (containing 1% glacial acetic acid) mixture (30:70 v/v) as mobile phase. To monitor preservatives (benzoic acid, parabens, sorbic acid, dehydroacetic acid, and their salts) in herbal liquid preparations, a group of 47 samples was divided into two different group: preservative labeled group and unlabeled group. From the results, the contents of preservatives in 31 samples of preservative labeled group fell under KFDA regulations, and the contents of dehydroacetic acid in 6 samples of preservative labeled group were not followed by KFDA regulations. Preservatives were detected in 3 samples out of 10 samples in preservative unlabeled group.

While depressives tend to be preoccupied with their own grief and the negative aspects, they might lack the capacity to interact with outside world. With the intention to determine whether depressives might have certain characteristics regarding empathic behavior, as behavior is highly based on responsiveness to others, we examined the relationship between emotional empathy and depression. In addition, we examined the mediating effect of self-criticism on the relationship between emotional empathy and depression. Data was collected from 146 online university students and analyzed using the correlation and multiple regression model. Results showed that perspective taking, which is the cognitive aspect of empathy, was negatively correlated with depression. Concerning the emotional aspects of empathy, both empathic responding and empathic concern were negatively correlated with depression, while personal distress was positively correlated with depression. Regression results, which set the empathy related variables as predicting variables, found perspective taking decreased depression, and personal distress enhanced depression. In addition, personal distress showed significant enhancing effect on depression and was completely mediated by self-criticism. With the result, implications and limitations of this study were discussed.

The purpose of this study was to examine how a leader's organizational citizenship behavior (OCB) affects subordinates' interpersonal citizenship behavior (ICB) and job stress levels. A leader's OCB involves taking-charge behavior, loyal boosterism, and the industry. We hypothesized that leader-member exchange (LMX) would mediate the relationship between leader's OCB and subordinates' ICB and job stress level. We tested the model using a sample of 293 employees from different organizations from September 2019 until November 2019. We conducted confirmatory factor analyses of the variables and analyzed the data by using structural equation modeling. We also conducted a CFA to assess the fit of a three-factor model for the leader's OCB items. Empirical findings show that LMX fully mediated the effect of leader's OCB on employees' ICB and job stress level. Leader's OCB had a positive effect on LMX. Moreover, LMX had a positive effect on employees' ICB but had a negative effect on job stress. We found support for our hypotheses that leader's OCB is positively related to ICB but negatively related to job stress, and this relationship is mediated by LMX. We discuss limitations, implications for practice, and future research.

Whereas the early financial information technology invested a large amount of investment on developing and adopting its own new systems. it is now focusing on reducing expenses and improving internal efficiency but applied for securing a company's competitive advantage considering the long term strategic level. As relevant researches, studies on information system quality and performance are actively going on. In previous research, the relations of the influence on the financial performance by information system quality or absorption capacity have been reviewed. In other words, the information system quality and absorptive capacity, respectively, in the position of the independent variables have been studied as a factor to have a significant effect on financial performance while the research on the relationship between these two variables is lacking. Thus, in this researches, quality of financial information systems and the absorptive capacity, respectively, as independent variables and parameters on the mediating effect on the financial performance were researches. As a result, quality of financial information systems showed a positive effect on the performance of company, the absorption capacity was perfect to play the role of mediating one. However, absorptive capacity as an independent variable has a positive impact on financial performance, but the quality of financial information systems as a parameter was not affected in any manner.
