The aim of this study was to investigate the factors affecting earth science problem-solving performances of elementary school pre-service teachers. The participants of the study were 81 students attending an elementary school teacher education university. The instruments of the study were paper-and-pencil tests, questionnaires, and interviews. The tests mainly measured the participants' problem solving abilities in the motions of the moon and the planets. Correlation and multiple regression techniques were used for data analysis. The results demonstrated that the pre-service teachers' problem solving abilities were low. Problem-solving performances were affected by the procedural knowledge, the participants' perception of the past earth science performance, self-efficacy, and the prerequisite declarative knowledge. Contrary to our expectation, the spatial visualization ability was not found to be related to the problem-solving performances. Implications of the study are drawn, and suggestions are made for further research.

This study shows the effect of inventory policy change from supplier-based to customer-based. We focus on the service level, cost, and information distortion of the Military Supply Chain(MSC) with System Dynamics. We design MSC model according to field practician interviews by using Vensim. The simulation makes a comparison between supply-based inventory policy performances and order-based inventory policy performances. In order to evaluate the MSC performances, we measure the accumulation of backlog(service level), supply chain cost, and order percentage overshoot(information distortion). The results show that 1) changing inventory policy from supplier-based to end customer order-based gets a good customer service, reduces MSC cost, and prevents information distortion, 2) changing inventory policy from supplier-based to immediate customer order-based reduces a small amount of MSC cost and deteriorates customer service, and 3) supply level is main factor for MSC performances improvement. This study implicates the policy change makes a improvement of MSC performance without introducing information system.

In the paper, we analyze the performances of random access channels in multi-service multi-user OFDMA systems. The resource of the random access channels in OFDMA systems is the nubmer of available sub-channels and PN-codes. For given available sub-channels and PN-codes. we analyze the performances of the random access channels of OFDMA systems according to three resource allocation methods (resource full sharing, resource partial sharing, resource partition) in tenus of the access success probability, the blocking probability, the access delay and the throughput of each service class. Further, we find the feasible region of the access probability of each service class in which the allowable minimum access success probability, the allowable maximum blocking probability and the allowable maximum access delay are satisfied. The results also can be utilized to find proper region of the access probabilities of each service class for differentiated quality of service(QoS)s, and for the system operations.

This empirical research examined the effects of organizational service orientations on business performance since the service orientations had been considered very importantly for delivering excellent service quality in many studies. The purpose of this study was to investigate the relationships among service orientations, customer orientations, employees' job satisfactions and business performance in medical service organizations. A model and hypotheses on the basis of this model were developed. And data from employees in medical service organizations were collected using questionnaires. Respondents were asked to related variables of their organizations. A total of 217 questionnaires collected were used to test hypotheses. The results obtained were as follows; first, service orientation factors had a positive significant effect on customer orientations, employees' job satisfactions and business performances. Second, employees' job satisfaction had a positive significant effect on their customer orientations. Third, customer orientations and employees' job satisfactions had a positive significant effect on business performances. Thus, it is advisable for managers or operators to emphasize service orientations in medical service organizations. This study is specific to ambulatory service in a medical service organizations, so generalizing the results to other area may not be possible. Although this study may help to guide the roles of service orientations, customer orientations, employee satisfactions and business performances in medical service organizations, future studies should consider other relative variables.

Perception of outsource workers among Incheon Int'l airport employees was reviewed about the service performances of winning the ASQ awards in 11 consecutive years. 85% of Incheon airport operating authority(Incheon International Airport Corp.) and its outsource companies employees was composed of outsource workers. Thus, their thoughts might represent the overall perception of airport operating authority employees. The perception on the service performances of winning the ASQ awards was analyzed by researchers using attribution theory model. It is useful to apply attribution modeling in order to analyze the causal relationships among variables. Attribution is the process by which individuals explain the causes of behavior and events. Attribution theory is the study of models to explain those processes. According to empirical analysis, it was found outsource workers attributed the excellent service performance of Incheon airport to such an internal factor as service competence. However it was also implied they attributed to such external factors as the positive relationship and institutional support from airport and government authorities.

The study was undertaken to investigate the validity of milk urea concentration as an index of the reproductive performances in crossbred Karan-Fries (Holstein Friesian${\times}$Tharparkar) cows under farm condition. Milk urea was analysed in noon milk samples (1200 to 1300 h) to interrelate with the interval from parturition to first service, number of insemination per conception, first service conception rate and service period. Milk progesterone (P4) was analysed in noon milk samples on the day 1, 10, 20 and 30 post insemination to study the effect of milk urea concentration on early embryonic mortality. The interval from parturition to first service was found significantly (p<0.01) higher ($77.2{\pm}5.5$ days) when milk urea concentration was ${\geq}63.4mg/dl$. The average milk urea concentrations (mg/dl) were found $42.1{\pm}2.5$, $47.9{\pm}1.5$ and $50.3{\pm}3.1$, respectively in cows that conceived at $1^{st}$, $2^{nd}$ and $3^{rd}$ insemination. However, the variation was not statistically significant. The first insemination conception rate was found significantly (p<0.05) higher (68.8%) when milk urea level was ${\leq}32.4mg/dl$. The service period was found significantly (p<0.05) higher ($125.4{\pm}8.8$ days) when milk urea concentration was ${\geq}45.1mg/dl$. The milk P4 level indicated that the cows, those were detected as non-pregnant on day 60 post insemination were initially pregnant but the pregnancy was terminated sometime during the day 30 to 60 post insemination. The study indicates that the milk urea values may be used as an index of reproductive performances in dairy herd when individual animals are not being monitored for nutritional status. The altered milk urea values may be utilised by the farmers as ready reference to rectify the protein and energy nutrition in cows to achieve the better reproductive performances in herd.
