산성주석도금욕중에서의 C - Dip package 상의 Tin - bridge 형성기구와 그의 억제법 ( 2 )

酸性光澤 주석 鍍金시 C-Dip package에 사용된 PbO-ZnO-B₂O₃系 solder glass 表面上의 Tin-bridge 形成機構를 說明코저 하였다. 豫備處理用 酸溶液에 의해서 形成된 solder glass 表面의 反應生成物이 陰極還元을 하므로서 Tin-bridge가 形成함을 알았으며 '또한 이 Tin-bridge를 形成할 수 있는 鍍金溶 條件을 변경시키므로서 Tin-bridge 形成의 內容을 說明할 수 있다. solder glass의 特性을 검토하므로서 과산화수소 용액에 의한 Tin-bridge 形成을 抑制할 수 있다. We investigate the mechanism of a tin-bridge formation on the solder glass surface during acid bright tin plating of a C-Dip package. In the PbO-ZnO-B₂O₃ system under study, the formation is found to be primarily due to the cathodic reduction the glass surface. And these sulfates, mainly PbSO₄, are shown to be the products of a precleaning with acids. The bath conditions are varied to see their effect on the tinbridge formation. We find that the formation can be avoided by pretreating the glass surface with oxyful. Possible mechanisms for this are discussed.

Primary lymphoma of the thyroid is a relatively rare malignant tumor of the thyroid. It is known to be frequently associated with Hashimoto's thyroiditis. In Korea, a few cases of primary lymphoma of the thyroid have been reported and most of these cases were in the stage I E or II E. Recently, we experienced a case of the primary thyroid lymphoma, stage IV E associated with Hashimoto's thyroiditis in a 70-year-old woman who presented with dysphagia and dyspnea due to rapidly enlarging neck mass. She was treated with combination chemotherapy(cyclophosphamide, adriamycin, vincristine and methylprednisolone) and local radiotherapy and achieved partial response with resolution of dysphagia and dyspnea(J Kor Soc Endocrinol 9: 390-394, 1994).
Considerations of Sustainable High-rise Building Design in Different Climate Zones of China
Wan, Kevin K.W.,Chan, Man-Him,Cheng, Vincent S.Y. Council on Tall Building and Urban Habitat Korea 2012 International journal of high-rise buildings Vol.1 No.4
Buildings, energy and the environment are key issues that the building professions and energy policy makers have to address, especially in the context of sustainable development. With more tall buildings constructed in China, the impact on energy consumption and carbon emission would be great from buildings (2% increase of carbon dioxide annually between 1971 and 2004). The imperative was to investigate the building energy performance of high-rise in different climate zones and identify the key design parameters that impose significantly influence on energy performance in sustainable building design. Design implications on glazing performance, sizing of the ventilation fans, renewable energy application on high-rise building design are addressed. Combination of effective sustainable building design strategies (e.g., building envelope improvement, daylight harvesting, advanced lighting design, displacement ventilation, chilled ceiling etc.) could contribute more than 25% of the total building energy consumption compared to the international building energy code.
EXPLORING THE PSYCHOLOGICAL IMPACTS OF SERVICE RECOVERY STRATEGIES ON POTENTIAL CUSTOMERS
Elisa K. Chan,Lisa C. Wan,Maggie Y. Chu 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07
Service recovery strategies have been examined for their effectiveness in compensating for the customer’s loss and in restoring customer satisfaction. Current research on service recovery has largely focused on the customer involved. For instance, the most common recovery strategies hotels used for the guest involved are compensatory (e.g., discount), corrective (e.g., correction), and personal response (e.g., apology). Service recovery research suggest that, while corrective responses are viewed by customers as the minimal action, both apology and compensation have been shown to be effective in increasing customer satisfaction (e.g., Goodwin & Ross, 1992). Due to the prevalence of online reviews, our understanding of service failure and recovery must expand beyond the customer involved to include potential customers who are searching online. The difference between the customer involved and the potential customer is that while the focal customer suffered an economic or psychological loss, the potential customer has not. Past studies suggest that this difference may change the attribution tendency of potential customers (e.g., Wan, Chan, & Su, 2011). Consequently, one can expect that potential customers may use different criteria in assessing recovery strategies. For instance, in line with the equity theory which posits that people in general seek fairness in social interactions (Blodgett et al., 1997), potential customers might be more concerned about justice rather than the compensation. From the company’s perspective, in order to recover effectively from a service failure, it must know whether what works for the customer involved would also work for potential customers. The current research provides evidence that potential customers’ reaction to an online review and a hotel reply is contingent on the perceived similarity between this potential customer and the focal guest (i.e., the customer involved in the incident that the review describes), the type of hotel reply (i.e., no reply, apology, and explanation with no apology). Moreover, results suggest that the psychological mechanism that underlies this relationship is not due to negative emotions but a sense of vulnerability.
