  • 금속이행이란 소모성 전극을 이용한 arc 용접에서 금속이 용융된 와이어로부터 모재로 이동하는 현상을 말하며 넓게는 용적의 이행 뿐만아니라 스패터등과 같은 불필요한 이행까지로 포함하는 의미이다. 용접시 스패터와 흄(fume)발생, 용입형상, 용접자세, 용융지안정성 및 용접부의 기계적 성질 등이 금속이행형태에 의해 많은 영향을 받기 때문에 효과적인 용접을 위해서는 이 금속 이행 형태를 적절히 조절해야 한다. 이를 위해서는 금속이행형태, 금속이행기구, 금속이행에 미치는 여러 가지 변수 등에 대하여 아라야 할 필요성이 있으며, 이러한 필요성 때문에 많은 사 람들이 오래 전부터 금속이행현상에 관한 연구를 수행하여 왔다. 그러나 용적이 고온이 arc속에 서 짧은 시간내에 고속으로 이행하기 때문에 금속이행현상의 연구에는 많은 어려움이 있으며, 현재까지도 정확한 금속이행현상에 관한 이론은 밝혀지지 않고 있다. 따라서 금속이행에 관해서 는 앞으로도 많은 연구가 필요하며 본 해설은 현재까지 연구발표된 금속이행에 관한 자료들을 종합정리하였다.

  • This study analyzed problems of operating performance bond for public works and derived some suggestions for improvement. The Contract Law for Government Owner requires to submit performance bond which guarantees performing the construction contractor pays back compensation money when the obligation is not executed. Currently, first bid eligibility for participation is exactly required for executing company of performance bond obligation, not considering volume, technical level, and special type of remaining works. In collaboration contract, if guarantee accident occurs, it is obliged for remaining collaboration contractors to be qualified to fulfill the whole contract. This study proposes following improvement plan to solve problems of current performance bone in public works. Firstly, qualification criteria must be deregulated exceptionally for selecting proper contractor, which executing performance bond obligation, considering progress and characteristics of remaining works. Secondly, In collaboration contract, the prerequisite of remaining contractors' should be deregulated as 'implementation requirement of the remaining works'from'implementation requirement of the whole work'. Finally, defect responsibility should be included in liabilities of performance bond by specifying that owner or guarantee agency bear them.

  • It is expected reasonably that firms are likely to be motivated to engage in cooperate social responsibility(CSR) more effectively and efficiently in order for sustainable growth when partnerships on supply chain are willing to embrace the initiative for CSR actively rather than a firm's effort. Given that this is a SCM(Supply Chain Management) approach to CSR, the SC-CSR(Cooperate Social Responsibility in Supply Chain), which encourage all partners on supply chain to apply it, can provide larger social impact. This study is to verify the effect of SC-SCR on the willingness to initiate CSR in small and medium-sized enterprises. As a result of empirical analysis, the application of SC-SCR has positive effect on the willingness of small and medium-sized enterprises to initiate social responsibility by promoting the situational needs. This results indicates that helping firms observe ISO 26000, the recognized international standard for CSR, the motivation for SCR can be reinforced by making partners on supply chain respect CSR.

  • Migration of low molecular weight components from expanded polystyrene (ESP) to distilled water was measured at different temperature conditions. Overall migration and specific monomer migration were measured. Diffusion model based on Fick's law was used to determine the apparent diffusion coefficients at various experimental conditions. The overall and specific migration levels were estimated to give some practical implications for regulatory guideline development and safe package design. Diffusion coefficients for overall migration in KMnO$_4$ oxidizable extractives and specific migration of styrene monomer from ESP at 6$0^{\circ}C$ were 0.030 and 6.8${\times}$10$^{-5}$ $\textrm{mm}^2$/h, respectively. Their temperature dependence could be explained by Arrhenius equation with respective activation energies of 80.5 and 98.6 kJ/㏖. Experimental conditions ensuring desired migration level were suggested for reliable examination of migration from the packaging material. Some explanatory estimations of migrations were given for some typical conditions of potential usages.

  • The purpose of this study was to identify blood and body fluids exposure, and factors influencing compliance with standard precautions among nurses. Participants consisted of 144 nurses in three general hospitals located in C province. Data were collected using a questionnaire that consisted of awareness, compliance, safety environment and attitude toward standard precautions. A total of 40.3% of participants had been injured by syringes or sharp tools that had already been used for patients within the last 1 year 1.01 times. Moreover, 22.9% of participants had been exposed to blood and body fluid of patients 1.06 times within the last 1 year. The mean score for compliance with standard precautions was lower than its awareness. There was a significant correlation between compliance and awareness and a safe environment. Multiple regression revealed an adjusted $R^2$ of 0.166 with the awareness score serving as the major predictor variable for compliance of standard precautions. Therefore, it is necessary to develop strategies to apply to systemic and continuous education regarding standard precautions and to foster a safe environment to enhance nurses' compliance with standard precautions.

  • The migration potential of volatile organic solvents widely employed in the printing process of food packaging was investigated by using a closed experimental system, which contained a food sample and a paper sheet spiked with the contaminant solvents. The studied organic compounds included toluene and p,m,o-xylene which are relatively highly volatile. Typical food samples of caramel, beef jerky and butter were selected based on their chemical composition and were assigned to the migration system at 10, 25 and 4$0^{\circ}C$. The equilibrated migration level was very high with almost complete transfer in the butter with high fat, while caramel of high carbohydrate content and beef jerky of high protein showed migration degree of 37∼56% and 37∼77%, respectively. Temperature did significantly influence the migration on beef jerky with higher level at higher temperature. There was no difference in the migration level among the solvents.

  • This study was a descriptive investigation to identify the influence of nurses' moral sensitivity and safety of their environment on compliance with standard precautions. Participants consisted of 214 nurses in one general hospital and data were collected using a questionnaire that consisted of moral sensitivity, safety of environment and compliance with standard precautions from 1-15 August 2017. Data were evaluated by the independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. The mean scores of moral sensitivity, safety of environment and compliance with standard precautions were 5.05, 5.76 and 4.50, respectively. Moreover, compliance with standard precautions was significantly positively correlated with moral sensitivity and safety of environment. Additionally, multiple regression revealed an $R^2$ of 0.253 with the department (ER, ICU), age and safety environment serving as the major predictor variables for compliance with standard precautions. However, the influence of moral sensitivity on compliance was not identified. Therefore, to increase compliance with standard precautions among nurses, it is necessary to provide continuous educational programs for new nurses, customized programs considering departmental characteristics and administrative support of institutions to enhance safety of the environment.
