  • This paper tried to examine the effect of the policy on companies' CSR activities and what kind of a role does CSR have in determining Customer Loyalty in Indonesia. This paper is divided into two parts, the first part is designed to find out whether the Indonesian government law has successfully made the companies perform better CSRs. We do this by using the ICGC Index of the companies registered and comparing their scores before and after the implementation of the policy. We will then use the paired sample t-test to find out if there is an increase in the overall scores of the companies and/or only the natural resource-related companies. The result showed an upward trend in the ICGC scores for all the companies which the Indonesian government law is intended to. In the second part, Manfred Schwaiger's components and parameters of corporate reputation was referred and used on Indonesian customers. We asked participants whether they think natural resource-related companies perform better CSRs and then we also tried to find out what factors really affect their loyalty towards companies or brands by conducting Multiple Regression Analysis. From the 4 factors that we have prepared, which consist of Performance, CSR, Quality and Attractiveness, Quality is the most influential towards determining our survey participants' Customer Loyalty. Surprisingly, CSR is insignificant in directly influencing Customer Loyalty. But, our research did find out that CSR does moderate Quality and Performance in their relationship with Customer Loyalty. Meaning that CSR has no effect in a direct relationship but it can increase the effect of Quality and Performance in determining Customer Loyalty. Unfortunately, CSR has no moderating effect in increasing the effect of Attractiveness towards Customer Loyalty.

  • Objective : The aim of this study was to evaluate the outcomes of the GnRH antagonist (Cetrotide) minimal stimulation protocol comparing with GnRH agonist combined long step down stimulation protocol in PCOS patients. Materials and Method: From Apr 2001 to May 2002, 22 patients (22 cycles) were performed in controlled ovarian hyperstimulation using by GnRH antagonist and GnRH agonist for PCOS patients. GnRH antagonist (Cetrotide) combined minimal stimulation protocol was administered in 10 patients (10 cycles, Study Group) and GnRH agonist long step down stimulation protocol was administered in 12 patients (12 cycles, Control Group). We compared the pregnancy rate/cycle, total FSH (A)/cycle, Retrieved oocyte/cycle, the incidence of ovarian hyperstimulation syndrome, multiple pregnancy rate between the two groups. Student-t test were used to determine statistical significance. Statistical significance was defined as p<0.05. Results: Group of GnRH antagonist (Cetrorelix) minimal stimulation protocol produced fewer oocytes (6.4 versus 16.3 oocytes/cycle) using a lower dose of FSH (22.2 versus 36.1 Ample/cycle) and none developed OHSS and multiple pregnancy. Although the trends were in favour of the GnRH antagonist (Cetrorelix) protocol, the differences did not reach statistical significance. This was probably due to small sample size. Conclusion: The use of GnRH antagonist reduce the risk of ovarian hyperstimulation and multiple pregnancy. We suggest that GnRH antagonist might be alternative controlled ovarian hyperstimulation method, especially in PCOS patients who will be ovarian high response.

  • The purposes of this study were to measure the service mind and customer orientation of employees and to identify the effect of service mind on customer orientation in elementary school foodservices. The questionnaires were distributed to foodservice employees of the 19 elementary schools, but collected from 12 schools in Gwangju, Gyeonggi. The statistical data analysis was completed using SPSS (ver. 18.0) for the independent sample t-test, ANOVA, Cronbach's alpha, principal component analysis, hierarchical & K-means cluster analysis, Pearson' correlation analysis, and multiple regression analysis. Foodservice employees highly rated their service mind (3.94 out of 5 points), especially their perceptions on the importance of service (4.13 points). The effort to provide service was significantly different depending on the serving place (P<0.05). Employees had a high level of customer orientation (4.02 points), which was significantly influenced by age, position, or career (P<0.05), and cook license (P<0.01). As a result of cluster analysis for service mind, employees were divided into two groups: a low-service mind group (cluster 1) and a high-service mind group (cluster 2). Cluster 2 had a significantly higher overall customer orientation than cluster 1 (P<0.001). The pride in providing services (${\beta}$=0.390, P<0.01) and the perception of the importance of services (${\beta}$=0.297, P<0.05) showed a significant and positive effect on customer orientation.

  • Purpose - With growing competition in the service distribution industry, the importance of managing customer complaints has increased. If firms handle customer complaints effectively, they can strengthen customer loyalty and repurchase intention. Many studies have focused on customers expressing complaints, yet research on silent customers is scant. This study focuses on two types of complainers and non-complainers. In other words, this study is to examine the value of voice complaint intention and no-action intention. This study also investigates how perceptual and relational factors affect complaint intention. Research design, data, and methodology - This study was carried out using the survey with undergraduate students who have faced a service failure in a retail store(fast foods, electronics, apparel). And if such complaint were to occur again, respondents were asked about any possible action they would take. 300 questionnaires were distributed and a total of 279 respondents provided complete and usable data. The sample consisted of 158 males(56.6%) and 121 females(43.4%). The structural equation modeling analysis was used for the hypothesis test. Results - The results are as follows. First, attitude toward complaining, likelihood of successful complaint, and ease of complaint were positively related to voice complaint intention. Second, attitude toward complaining, likelihood of successful complaint, and ease of complaint were negatively related to no-action intention. Third, commitment was positively related to voice complaint intention but didn't have a significant negative impact on no action. Forth, voice complaint behavior reduced switching intention and no-action intention enhanced switching intention. Conclusions - The findings of this study confirm the value of complaint behavior and show voice complaint intention and no-action intention should be managed differently. Voice complaint intention is evaluated positively because it reflects customers' concerns about the company, while no-action intention is evaluated negatively. Attitude toward complaing is the most effective in increasing voice complaint intention and likelihood of successful complaint is a major factor in reducing no-action intention. Also, in explaining switching intention, voice complaint intention plays a more important role than no-action intention.

  • Statement of problem. Fracture of the tooth-colored superstructure material is one of the main prosthetic complications in implant-supported prostheses. Purpose. The purpose of this in vitro study was to compare the fracture strength between the cement-retained implant-supported metal-ceramic crowns and the indirect composite resinveneered metal crowns under the vertical compressive load. Material and methods. Standard implants of external type (AVANA IFR 415 Pre-mount; Osstem Co., Busan, Korea) were embedded in stainless steel blocks perpendicular to their long axis. Customized abutments were fabricated using plastic UCLA abutments (Esthetic plastic cylinder; Osstem Co., Busan, Korea). Thirty standardized copings were cast with non-precious metal (Rexillium III, Pentron, Walling ford, Conn., USA). Copings were divided into two groups of 15 specimens each (n = 15). For Group I specimens, metal-ceramic crowns were fabricated. For Group II specimens, composite resin-veneered (Sinfony, 3M-ESPE, St. Paul, MN, USA) metal crowns (Sinfony-veneered crowns) were fabricated according to manufacturer's instructions. All crowns were temporary cemented and vertically loaded with an Instron universal testing machine (Instron 3366, Instron Corp., Norwood, MA, USA). The maximum load value (N) at the moment of complete failure was recorded and all data were statistically analyzed by independent sample t-test at the significance level of 0.05. The modes of failure were also investigated with visual analysis. Results. The fracture strength of Sinfony-veneered crowns ($2292.7{\pm}576.0N$) was significantly greater than that of metal-ceramic crowns ($1150.6{\pm}268.2N$) (P < 0.05). With regard to the failure mode, Sinfony-veneered crowns exhibited adhesive failure, while metal-ceramic crowns tended to fracture in a manner that resulted in combined failure. Conclusion. Sinfony-veneered crowns demonstrated a significantly higher fracture strength than that of metal-ceramic crowns in cement-retained implant-supported prostheses.
