The objective of this study is to investigate various jobs and foodservice environments, as well as work performances of school foodservice dietitians and nutrition teachers in accordance to the years of service in Daejeon and Chungnam provinces. A survey was conducted among school foodservice dietitians and nutrition teachers; a total of 415 from selected elementary, middle and high schools in the areas. In this study, we surveyed the participants and analyzed the current state of general characteristics, status of their job environments and foodservice environments by frequency, and the averages and differences in work performance with regard to 12 work parts and 57 works using one-way ANOVA and Duncan's multiple range test according to the years of service. Six parts among 12 work parts were significantly different in work performance according to the years of service. The 6 work parts were menu (nutrition) management, utensil recovery and management, sanitation management, foodservice administration & evaluation, dietary habit guide, and other works. The 11-15 years group ranked as the top on the total score and means of work performance. While the 16-years or more group, 6-10 years group, and under 5 years group followed consecutively. Correlation analysis between job or foodservice environments and work performances showed that work performances of school dietitians were mostly influenced by employment status, education level, and annual salary among the variables of job or foodservice environments. Other works, dietary habit guides and menu management were mostly influenced by variables of job and foodservice environments.

The study was conducted to investigate the effects on environmental factors on the reproductive performance of Korean native cattle based on the data from 13, 588 records which were surveyed from 1983 to 1992. The results obtained in this study are as follows; 1. Mean performaces of the reproductive traits were 510.2days for the age at 1st service, 525.0days for the age at 1st conception, 808.7 days for the age at 1st calving, 102.5 days for the days to 1st conception postpartum and 388.6 days of the calving inverval. The cows of Chunbuk province were tended to be bred and calved at younger age and showed shorter calving interval than those of other provinces. 2. The effect of birth year was significant for the reproductive performances, especially, in 1986~1987 when the cattle prices dropped sharply and reproductive performances were poor. 3. The times of 1st service and 1st conception of heifers calved in spring tended to be delayed. Days to 1st conception postpartum, calving interval and days to 1st service postpartum of cows calved in fall were shorter than other calving season's cows. 4. Days to 1st conception postpartum, calving interval and days to 1st service postpartum of cow's were shortened and gestation length was prolonged as the number of parity increases.

Purpose: The purpose of this study is to confirm that multichannel distribution strategies may be used for cultural and artistic products such as musicals, just as for general consumer goods, through a case study on the distribution strategy for a musical title. In addition, a distribution strategy for cultural and artistic products is proposed based on the analysis of the case. Research design, data, and methodology: Qualitative research methods, such as case study research and in-depth interviews, were used in this study. Results: The case study of the Korean musical Myeongdong Romance confirmed that multichannel distribution strategies may be used for musicals, including performances at theaters, Naver TV screenings (a service linked to an Internet portal), LGU+ screenings (an IPTV and OTT media service), DVD releases, and screenings of recordings of Romance Hall performances. Conclusion: For cultural and artistic products such as musicals, distribution channels can be diversified to incorporate the simultaneous use of multiple channels. New cases involving other cultural and artistic products and services to which this distribution strategy is applicable may be identified, and the strategy may be implemented along with new technologies to reduce costs further.

Conventional X-band marine radar has been used as one of the effective tools for collecting and retrieving ocean surface information parameters for three decades. Several wave information extracting algorithms have been designed in such a way that they can be utilized for efficiently estimating sea surface wave parameters such as current velocities, wave direction, significant wave heights in VTS (Vessel Traffic Service). However, their performances are still restricted. For the purpose of overcoming the performance limits, in this paper, first the conventional algorithms are analyzed and their performances are compared, and then a new control algorithm is proposed. Furthermore, we try to improve the estimation performances of typical wave parameters including wave directions and significant wave heights by introducing linear regression model in the process of computing wave information extraction. Through several simulations with the X-band radar images, it is shown that the proposed method is very effective in estimating the wave information compared to the real measured buoy data.

In this paper, a procedure is proposed to optimize bogie suspension parameters in view of minimizing wheel wear produced by curve negotiation, though meeting stability requirements. The problem is dealt with in the form of a constrained minimization problem, in which wheel wear evaluated over a given service scenario is introduced as the cost function to be minimized, and the requirements on vehicle stability are formulated in terms of constraints. The procedure is applied to the case of a non-powered passenger car for high-speed service, and the results obtained are discussed. It is shown that long wheelbase bogie may provide better overall performances than bogies having comparatively short wheelbase. Furthermore, a sensitivity analysis is performed, to define the effect on the optimization results of improving the performances of the yaw dampers in the bogie and of using a different wheel profile.

Purpose - Our primary goal of this study is to investigate the positive relationship between female managers' self-determined motivations (i.e., RAI: relative autonomy index) and job performances with the mediation of their job creativity in service industries. This study also examines the moderating role of creative efficacy on the relationship between female managers' self-determined motivations and creativities. Finally, based on mediation and moderation hypotheses, we also tested moderating effect of creative efficacy on the mediation effect of job creativity. Research design, data, and methodology - Drawing on SDT(Self-determination theory) and COR(conservation of resources) theories, we developed three research hypotheses. Service female managers from a several service organizations(i.e. banking, retailing, and restaurant/hospitality service) in South Korea were surveyed using self-administered instrument for data collection. A total of 331 usable questionnaires were obtained after list-wise deletion. To test reliability and validity of measurement model, we employed the CFA(confirmatory factor analysis) using M-plus 8.1 Software. Also, internal consistency was tested by Cronbach's α. We, furthermore, used the SPSS PROCESS MACRO 2.16, which was suggested by Hayes (2013; 2015), to test mediation, moderation, and moderated mediation. Results - Our results revealed that self-determined motivation and job performance were positively and fully mediated by job creativity. Furthermore, the positive relationship between female managers' self-determined motivations and job creativities was stronger when their creative self-efficacies were high than when it was low. In addition, female managers' creative self-efficacies also amplified the positive relationship between their self-determined motivations and job performances with the mediation of job creativity. Conclusions - Our research empirically elaborated the previous model of self-determined motivation and manager/female creativity literature by presenting the findings that female managers' self-determined motivations significantly influence their job performances via job creativity and that creative self-efficacy effectively strengthen these positive impacts. Also, our research offered new insight for practitioners (i.e. top service managers) by suggesting that they may enhance female service managers' job performance if they pay more attention to employee creativity in service marketing.

본 연구는 교육대학교에서 1학기 동안 '과학교과교재연구 및 지도법'을 수강한 3학년 예비 초등교사 162명을 대상으로 생명영역 탐구 수행 경험이 과학자에 대한 이미지와 과학 교수 불안에 미치는 영향을 알아보았다. 수업은 3~4명이 한 조로 구성되어 10개의 실험 주제 중 한 주제를 선택하여 직접 탐구한 후 그 결과를 동료 예비교사들 앞에서 발표하는 형식으로 진행되었다. 초등 예비교사들의 과학자에 대한 특성에 대한 견해를 조사한 결과 탐구 수행 경험 전후에 관계없이 과학자를 신중하고, 지적 수준이 우수하며, 창의적이고, 근면하다고 생각한 반면, 예술적이고 종교적이라고 여기지는 않는 것으로 나타났다. 특히 지적능력이 우수한, 창의적인, 개방적인, 활발한, 책임감 있는 특성에 대해서는 탐구 수행후 더욱 긍정적인 반응을 보였다. 또한 초등 예비교사들의 과학자 그리기에서 나타난 과학자의 활동 유형은 탐구 수행 후 '실험활동'이 가장 많이 증가하였으며, 활동장소로는 활동유형과 관련된 '실험실'이 가장 많았다. 이이서 초등 예비 교사들의 탐구 수행 경험 전후의 과학 교수 불안을 확인해 본 결과, 과학지식, 탐구 수업 준비, 탐구 수업 운영, 모든 영역에서 통계적으로 유의한 차이를 보였다. 이는 탐구 경험이 과학 교수에 대한 자신감을 갖게 하는데 긍정적인 영향을 미치는 것으로 해석할 수 있었다.

This study is to examine the factors that influence the performances of service quality in university hospitals by investigating systematically the condition of service quality. A synthesis of the health care quality is conducted to identify physical quality, operating process quality, and human resources quality that relate to both the overall satisfaction and intention of revisit. Based on the proposed hypotheses, the relationships between the service quality factors and performance are examined using data collected from 167 patients in three hospitals, Korea. Reliability and validity tests are performed for examining its relationship with service quality in health care systems. Total eight independent variables with respect to three service quality levels and two dependent variables for performance are identified for relationships between service quality and performance in health care systems. The results provide health care managers with a managerial insight to the planning function of performance with service quality in health care systems as well as other operations (business, government, or other service organizations) systems. Implication of the study for theory, future studies, and practices are discussed.
