Ensuring timely ovulation concerning the service is valuable. A satisfactory conception rate can be achieved by making sure that ovulation occurs within 7-18 hours after artificial insemination (AI). Delayed ovulation is one of the disturbances commonly encountered in repeat breeding animals. Although demanding research, many studies have not been conducted. Therefore, we aimed to examine the relation between ovulation confirmation and conception rate in dairy cattle. The research findings showed that the signs of true estrus were bred 12 hours after the onset of estrus by AI in cattle. Also, the performance of AI on ovulation was confirmed by the presence of fluctuant Graafian follicles through rectal palpation. From the results, we confirmed that cow encountered delayed ovulation were bred again. The Conception rate in cows with confirmed ovulation was 51.9%, while for those without confirmed ovulation were 33.3%. In conclusion, the results indicate that ovulation confirmation will likely increase conception rate.

Due to fierce competition, many domestic fashion businesses are suffering difficulty in securing and maintaining customers. Accordingly, fashion companies are devoting all their energy to secure customers by using high quality and diverse strategies for distribution and promotion, and to secure loyalty by satisfying customers with the offer of excellent service. Thus, it is very important to provide systematic service recovery strategy available for handling service failure effectively. Therefore, the purpose of this study is comprehensively analyzing influences of expectation dis-confirmation and perceived justice for service recovery upon consumers' satisfaction and loyalty. The findings are as follows. First, as for the service failure that customers experienced, the more consumers who expect it to be recovered led to the higher formation of expectation-compensation dis-confirmation. Second, it was indicated that the higher seriousness in service failure that customers experienced led to the lower satisfaction and loyalty to service recovery. Third, as a result of examining influence of expectation-compensation dis-confirmation for service-failure recovery upon consumer satisfaction and loyalty, the customers who showed more positive dis-confirmation to expectation-compensation were indicated to form the more satisfaction and loyalty. Fourth, as a result of examining the influence of the perceived justice in the process of service-failure recovery upon customer satisfaction, all in 3 dimensions of justice had effect on customer satisfaction.

오래된 증거의 문제는 가설이 제안되기 이전에 이미 알려진 증거는 그 가설을 입증할 수 없다는 문제를 제기한다. 오래진 증거의 문제는 베이즈적 입증 개념에 심각한 문제를 제기하는데 그것은 관련 학자들의 많은 노력에도 불구하고 여전히 미해결의 상태로 남아있다. 이 글의 목적은 오래된 증거의 문제가 베이즈적 입증 개념에 대한 심각한 오해에서 비롯되었다는 점을 보임으로써 그 문제를 해결하는 것이다. 먼저 논의의 출발점인 오래된 증거의 문제가 분석되고 이어서 베이즈주의자들이 그 문제를 해갈하기 위해서 제안한 두 가지의 대표적 입장이 비판적으로 검토된다. 이러한 과정을 통하여 오래된 증거의 문제에 대한 기존의 논의들에서 공통적으로 발견되는 오해, 즉 설명과 예측의 맥락에서 나타나는 입증의 비대칭성이 무시되는 현상이 지적된다. 마지막으로 입증의 비대칭성을 이용하여 두 종류의 구별되는 베이즈적 입증 개념이 제시되고 오래된 증거의 문제에서 가정된 입증은 진정한 입증이 아니라는 점이 주장된다.

This study examined the customers' perception on Home Meal Replacement (HMR) products. Specifically, there were three research objectives: 1. to identify the customers' HMR purchase patterns and preference of HMR product development; 2. to identify the attributes of the HMR products that the customers perceive; and 3. to examine the customers' level of expectation-confirmation toward HMR product attributes according to the demographic characteristics. This study employed a self-administered survey that was distributed online from November 21~24, 2017. The sample of the study was the customers who had purchased HMR products in the six months prior to taking the survey. A total of 553 respondents completed the survey, which was used for data analysis. The results revealed the customers' HMR purchase patterns. The major HMR product type of purchase was ready to heat (52.6%), while the main reason for purchasing HMR products was convenience (83.2%). For the differences in the level of expectation-confirmation toward HMR products in accordance with the demographic characteristics of customers, the results indicated that there was a difference in the expectation-confirmation level according to age, whereas the respondents aged 29 and under showed a significantly higher level of time-saving for the preparation and ease of cooking (P<0.05) than the other age groups. In addition, there was a significant difference in the expectation-confirmation level for saving meal preparation time (P<0.05) and convenience (P<0.01) among the customer's occupation. These findings can provide the basis for a strategy for developing HMR products reflecting the rapidly changing customers' needs. HMR products should be developed according to the specific target market, as the study indicated that the respective customer segmentation resulted in a difference in their expectation toward HMR products.

본 연구는 형사사법판단 분야에서 광범위하게 판단 오류를 발생시키는 확증편향이 고의성 판단에 어떠한 영향을 미치는지 확인하기 위해 수행되었다. 이를 위해, 사건 가해자 및 피해자의 도덕적 특성을 다르게 조합한 중상해 사건과 사망 사건에서 확증편향이 고의성 판단에 영향을 미치는 심리적 기제를 확인하였다. 연구 결과, 참가자들은 사건 가해자와 피해자 모두 나쁜 사람들이 연루된 사건을 더 전형적인 범죄사건이라고 지각했고, 이러한 전형적인 범죄사건의 가해자에게 더 높은 고의성을 부여하였다. 특히, 확증편향이 높은 사람들은 더욱 범죄사건에 대한 고정관념과 일관된 방향으로 사건 가해자의 고의성을 높게 판단하는 것으로 나타났다. 그런데, 심각한 범죄사건에서는 이러한 확증편향의 조절효과가 사라지고 범죄의 전형성 효과만 나타나는 경향이 있었다. 마지막으로, 본 연구의 의의와 함께 고의성 판단을 왜곡시키는 편향을 감소시킬 수 있는 방안에 대해 논의하였다.

Purpose: The purpose of this study is to examine the factors that influence the pre-use expectation and the continuous usage intention of the OTT services. Methods: For empirical analysis, the survey for this study was administered with many anonymous people who had previously used any of the OTT services and valid 192 data were analyzed by SPSS and PLS-SEM. Results: The results of this study are as follows. Personalization and understandability in the information quality didn't significantly affect confirmation. Ease of use and search of the system quality significantly affected confirmation. Also, it was found that content diversity, content recency, and content playfulness as the characteristics of the content quality significantly affected the expectation confirmation. OTT service fees also significantly affected the expectation confirmation. It also significantly affected perceived usefulness and satisfaction. Finally, satisfaction positively influenced the continuouse intention to use. Conclusion: The findings of this empirical analysis shows that the specific characteristics related to the relationship of expectation confirmation, perceived usefulness, satisfaction, and continuous usage intention with respect to OTT services through the Post Acceptance Model (PAM). Because system quality, content quality, and service fees meeted users' expectations, OTT services need a strategy that can boost the users' positive perceptions or experiences by reinforcing these three factors.
