Kang, Minjung. 2018. “Functions of I mean in American Talk Shows”. The Sociolinguistic Journal of Korea 26(2). 63~84. This paper aims to find out roles of the discourse marker I mean in American talk shows. Ten interviews from six talk shows were analyzed for the investigation and the results indicate that there are some unique functions of I mean which do not seem to be mentioned in early studies: counter-accounting and footing shift functions. This study suggests that the counter-accounting function of I mean can appear in utterance-initial position when the interviewee does not agree with what the interviewer has mentioned. Also, the interviewee can use I mean as a footing shift marker to switch stances from an informative one to an entertaining one (or vice versa). Since these two functions seem to be connected to the institutional settings and goals of talk shows, it is crucial to study functions of I mean in accordance with types of institutional talk.

Several joining methods involving resistance welding, laser welding, ultrasonic welding and mechanical joining are currently applied in manufacturing lithium-ion batteries. Cu and Al alloys are used for tab and bus bar materials, and laser welding characteristics for these alloys were investigated with similar and dissimilar material combinations in this study. The base materials used were Al 1050 and oxygen-free Cu 1020P alloys, and a disk laser was used with a continuous wave mode. In bead-on-plate welding of both alloys, the joint strength was higher than the strength of O tempered base material. In overlap welding, the effect of welding parameters on the tensile shear strength and bead shape was evaluated. Tensile shear strength of overlap welded joint was affected by interfacial bead width and weld defect formation. The tensile-shear specimen was fractured at the heat affected zone by selecting proper laser welding parameters.

The use of light-weight Al alloys in the automotive industry is increasing to meet requirements for fuel efficiency and emission reduction. Joining Al alloy to the conventional steel sheet is also very important issue with the increased use of Al alloy, and several joining processes have been introduced to enhance joining strength between dissimilar metals. This paper deals with a galvanic corrosion in the dissimilar metal joining. Salt spray tests up to 2000 hours were conducted on a self-piercing rivet, spot welded, adhesive bonded and weld-bonded joints, and cross-sections and tensile shear strength according the salt spray duration were analyzed at every 500-hour. Self-piercing rivet joint had relative low initial strength but the joint strength did not change regardless of the salt spray duration. The strength of other joints (spot welded, adhesive bonded and weld-bonded joints) decreased with the increase of salt spray duration and the corrosion behaviour of each joint was discussed.

국제적인 금융위기가 연달아 발생하면서, 금융리스크관리의 중요성이 어느 때보다 더 커지고 있다. 금융리스크관리의 주요 현안 가운데 하나는 리스크를 어떻게 측정할 것인가이며, 가장 널리 사용되고 있는 방법이 Value at Risk(VaR)이다. 금융자료가 최근 시장에서처럼 두꺼운 꼬리를 갖는 분포를 보일 때, 우리는 극단치 이론을 이용하여 VaR를 측정하는 방법을 고려할 수 있다. 이 논문에서는 꼬리가 매우 두꺼운 분포를 갖는 자료를 적합시킬 때 많이 사용되는 Peaks over Threshold(POT)를 이용하여 VaR를 측정하는 방법을 연구하였다. POT를 이용하기 위해서는 우선 일반화 파레토 분포(GPD)의 모수를 추정해야 하는데, 여기서 우리는 KOSPI 5분 자료를 이용하여 추정된 VaR의 성능을 살펴봄으로써 세 가지 다른 모수추정 방법을 비교하였다. 또한, Normal Inverse Gaussian(NIG) 분포에서 자료를 생성하여 두 가지 다른 모수추정 방법을 비교하기도 하였다. 이러한 비교를 통하여 KOSPI 수익률 자료의 첨도가 매우 큰 경우에는 최근 제안된 모수추정 방법들이 최대가능도 추정법에 비해 월등히 나은 성능을 보임을 알 수 있었고, 모의실험 자료에서도 같은 결과를 확인하였다. The importance of financial risk management has been highlighted after several recent incidences of global financial crisis. One of the issues in financial risk management is how to measure the risk; currently, the most widely used risk measure is the Value at Risk(VaR). We can consider to estimate VaR using extreme value theory if the financial data have heavy tails as the recent market trend. In this paper, we study estimations of VaR using Peaks over Threshold(POT), which is a common method of modeling fat-tailed data using extreme value theory. To use POT, we first estimate parameters of the Generalized Pareto Distribution(GPD). Here, we compare three different methods of estimating parameters of GPD by comparing the performance of the estimated VaR based on KOSPI 5 minute-data. In addition, we simulate data from normal inverse Gaussian distributions and examine two parameter estimation methods of GPD. We find that the recent methods of parameter estimation of GPD work better than the maximum likelihood estimation when the kurtosis of the return distribution of KOSPI is very high and the simulation experiment shows similar results.

This study investigates the fabrication of core-sheath nanocomposite fibers by locating germanium (Ge) and silicon dioxide (SiO₂) nanoparticles selectively in the sheath layer by co-axial electrospinning. Co-axially spun fibers were prepared by electrospinning a pure PVA solution and Ge/SiO₂/PVA solution as the core and sheath layer respectively. Core-sheath nanocomposite fibers were electrospun under a variety of conditions that include various feed rates for the core and sheath solutions voltages and concentric needle diameters in order to find an optimum spinning condition. Ge/SiO₂ nanocomposite fibers were also prepared by uni-axial electrospinning to compare fiber morphology and nanoparticle distribution with core-sheath nanofibers. Using scanning electron microscopy transmission electron microscopy and energy dispersive X-ray analy-sis it was demonstrated that the co-axial approach resulted in the presence of nanoparticles near the surface region of the fibers compared to the overall distribution obtained for uni-axial fibers. The co-axially elec-trospun Ge/SiO₂/PVA nanofiber webs have possible uses in high efficiency functional textiles in which the nanoparticles located in the sheath region provide enhanced functionality.

This investigation aims to identify the roles of the discourse marker ja in home shopping discourse. In 12 excerpts of home shopping discourse, ja has been found 8 6 times, used as a marker of adding more information, changing a subject, starting a new topic, focusing and suggesting. The analysis showed that the adding more information function, which is the most frequently used one (35 times), and the suggesting one were newly found in this type of discourse and directly related to the characteristic of the discourse: show hosts tend to provide as much information about the product as possible and to justify the consumption by suggesting various reasons. In addition, cases in which ja was used more than two times by one speaker were often found, which is connected to the fact that it is necessary to keep consumers attention for the purpose of selling products. Also, guests who occasionally appear to help the hosts never used ja, which is because only show hosts have the power to control the discourse. In the process of switching the topic (e.g. price, composition, product features, or rushing comments), ja was used as a subject-changing marker second most frequently (29 times), especially when making rushing comments. These findings turn out to be closely related to the distinctive features of home shopping discourse, demonstrating the importance of studying discourse markers within the context of institutional discourse.

The purpose of this research is to identify a general tendency of Burnout and a Inter-organization relationship among work experienced kindergarten teachers. Additionally, it lies to investigate how Burnout affects the Inter-organization relationship within the organization. For this purpose, 204 kindergarten teachers were surveyed from December 20, 2016 to January 15, 2017. Descriptive statistics quantity, Correlation analysis and hierarchical regression analysis have been adopted for data analysis using SPSS WIN 21.0 program according to the research questions. The results of the study are as follows. Firstly, Burnout appeared in the following order, administrative work pressure, a sense of crisis towards teacher s authority and skepticism about teaching. Relationships among work experienced teachers appeared to be the highest with peer groups within the organization. However, the relations with their principal of their kindergarten are relatively low. Secondly, it appears that there is a negative correlation between Burnout and relationships of work experienced teachers in kindergarten. Lastly, Burnout of experienced teachers show relative influence on human relations; inability is the highest and then skepticism about teaching follows. These results will provide a basis for work experienced teachers to reduce their Burnout in the early childhood educational field and maintain a desirable teaching career through balanced relationship.

의료 서비스의 실패 상황에서 서비스 회복 보상과 진정성이 서비스 이용 행동에 미치는 영향

강민정 ( Kang Minjung ),한상린 ( Han Sang-lin ),백민선 ( Baek Min Seon ) 한국소비자학회 2019 소비자학연구 Vol.30 No.6

본 연구는 의료 서비스의 실패 상황에서 의료 서비스 제공자가 제시하는 서비스 회복 보상과 진정성이 서비스 이용자의 이용 행동에 미치는 영향에 대하여 연구하였다. 의료 서비스는 고객의 건강 및 생명과 직접적인 관련이 되어 전문적인 서비스 수행이 필요하며, 고객은 서비스 실패 시 심각성을 크게 느낄 것이다. 그리고 서비스가 고객의 신체를 통해 이루어지기 때문에 서비스 제공자와의 접촉 빈도가 매우 높고, 고객은 서비스 제공자의 진정성에 대해 민감하게 느낄 것이다. 또한 고객의 건강 및 질병의 수준에 따라 서비스 제공자에 대한 의존도가 높아질 것이다. 이로 인해 다른 환대 서비스와는 달리 서비스 실패 시 서비스 회복 보상에 대한 선호와 서비스 제공자의 진정성에 대해 어떻게 인식하는가에 대한 연구가 필요하다고 판단하여 본 연구를 진행하였다. 분석결과 서비스 회복 노력 중 사과 및 자세한 설명만 몰입(감정적, 계산적, 규범적 몰입)에 정(+)의 영향을 미치는 것으로 나타났다. 또한 서비스 제공자의 진정성은 고객지향적 진정성만이 몰입(감정적, 계산적, 규범적 몰입)에 정(+)의 영향을 미치는 것으로 나타났다. 따라서 본 연구의 이론적인 관점의 시사점은 첫째, 서비스 실패 시 의료 서비스 기관에서 제공하는 서비스 회복 보상과 의료 서비스 제공자의 진정성 중 고객의 장기적인 거래 관계를 형성하는데 중요한 변수를 찾아냈다는 점이다. 둘째, 조사 대상을 다른 의료 서비스 연구에서 주로 볼 수 있는 서비스 접점에서 실패(예약, 대기 시간이 길어짐 등)가 아닌 의료 시술 및 수술을 받은 후 실패를 경험한 고객을 선정하였다는 점은 의료 서비스논문에서의 기여점이라고 볼 수 있다. 실무적 관점에서의 시사점은 의료기관에게 의료서비스 실패를 경험한 고객에게 제공해야할 마케팅 전략을 도출하였다는 점이다. The rapidly aging population, rising income levels and growing interest in well-being are changing the perception of quality of life, healthy life, and the importance of the medical service industry. As a result, market of medical service becomes more competitive. The independent variables consist of the monetary reward, the apologies and the details of explanation as a sub-directional variables. The authenticity is composed of 3 dimensions including service provider, service process, and customer-orientation. The intermediate variable is the commitment which has been reviewed by affect, continuity, a normative approach. It was selected the repurchase intention and the word of mouth as the sub-ordination variable. The definition of the failure for medical service meant dissatisfaction after the surgery or the treatment. The research has been executed toward the person who felt dissatisfaction after medical service. From the theoretical point of view of this study, the hypothesis test showed that only apology and detailed explanations among the sub-directional of service recovery efforts had positive effects on commitment(affective, continuous, normative commitment). In addition, only customeroriented authenticity, a subparameter of authenticity, has a positive effect on commitment (affective, continuous, normative commitment). The normative commitment effects on the verbal intention in the aspect of positive, the intention of verbal is supposed to effect on the intention of re-using significantly. The practical view of this study has been that apologies and detailed explanations are important recovery rewards for service customers who experience medical service failures during marketing activities to attract customers of the medical institution. It also suggests that customer-oriented authenticity rather than authenticity of service personnel or service processes is a key factor in the long-term relationship that can be shaped by the customer's desire to find and provide what services they need.
