  • Objectives: The purpose of this study was to verify the relationships among nursing work environment, job satisfaction, organizational commitment, and retention intention, as well as to clarify the factors that affect nurses' retention intention. Methods: The study included 163 nurses working in three general hospitals located in B city. Data were collected by a survey using self-administrated questionnaire and analyzed using the SPSS software. Results: The participants expressed a moderate level of retention intention. There were significant differences in retention intention by income (t=-2.13, p=.034) and intention to work (F=9.86, p=.001). The factors influencing retention intention were organizational commitment (${\beta}=.28$, p=.001), job satisfaction (${\beta}=.25$, p=.001), nursing work environment (${\beta}=.23$, p=.004), plan to work period (${\beta}=.13$, p=.027). These factors explained 55.3% of retention intention (F=41.079, p<.001). Conclusions: The findings showed that nursing administrators should develope programs that promote internal satisfaction for new nurses and strive to improve the human and physical aspects of the nursing work environment for career nurses.

  • Eight male cattle of Local Yellow breed with an average live weight of 121 kg and an average age of 18 months were used to evaluate the effects of different levels of sun-dried cassava foliage supplementation (Manihot esculenta) on intake, digestibility and N retention. Rice straw ad libitum and para grass (Brachiaria mutica) at 1% DM of BW comprised the basal diet. The study was arranged as a $4{\times}4$ double Latin square design, with cassava foliage contributing 0, 0.8, 1.6 or 2.4 g CP/kg BW. The cattle selected cassava leaves in preference to petioles. Petiole intake decreased from 64 to 48% of offered petioles when the cassava foliage proportion increased from the lowest to the highest level. The cattle consumed all the leaves at the two lower levels of cassava foliage inclusion and 91% at the highest level. Rice straw intake decreased significantly as the level of cassava foliage increased. Intake of DM, OM, NDF, and ADF increased significantly with increasing intake of cassava foliage. Daily DM intake per 100 kg BW increased from 2.7 to 3.2 kg with increasing cassava foliage intake. No effect on CP digestibility was detected when the level of cassava foliage increased. Digestibility of DM, OM, NDF and ADF was significantly higher in the group fed no cassava foliage than in the other groups. N retention increased from 16 to 28 g/d with the first level of cassava foliage inclusion, but levelled out at the two highest levels. N excretion increased in both faeces and urine as a response to higher intake of cassava foliage. Maximum N retention occurred when 40% of total N intake came from cassava foliage (equivalent to 1.3 g CP/kg BW).

  • Customer population management models can be classified into three categories: the first category includes the models that analyze the customer population at cohort level; the second one deals with the customer population at aggregate level; the third one has interest in the interactions among the customer populations in the competitive market. Our study proposes a model that can analyze the dynamics of customer population in consumer-durables market at aggregate level. The dynamics of customer population includes the retention curves from the purchase or at a specific duration time, the duration time expectancy at a specific duration time, and customer population growth or decline including net replacement rate, intrinsic rate of increase, and the generation time of customer population. For this study, we adopt mathematical ecology models, redefine them, and restructure interdisciplinary models to analyze the dynamics of customer population at aggregate level. We use the data of previous research on dynamic customer population management at cohort level to compare its results with those of ours and to demonstrate the useful analytical effects which the precious research cannot provide for marketers.

  • This paper discusses the 3-level charge pumping (CP) method in planar-type Silicon-Oxide-High-k-Oxide-Silicon (SOHOS) and Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) devices to find out the reason of the degradation of data retention properties. In the CP technique, pulses are applied to the gate of the MOSFET which alternately fill the traps with electrons and holes, thereby causing a recombination current Icp to flow in the substrate. The 3-level charge pumping method may be used to determine not only interface trap densities but also capture cross sections as a function of trap energy. By applying this method, SOHOS device found to have a higher interface trap density than SONOS device. Therefore, degradation of data retention characteristics is attributed to the many interface trap sites.

  • This research was carried out to determine the effect of dietary calcium(Ca) levels(low : 0.29, medium : 0.65 and high : 1.07%) on the digestibility, excretion and retention of nitrogen(N) phosphorus (P) in pigs fed diets supplemented with phytase(750U/kg). Twelve growing-finishing pigs(average body weight: 35kg) were divided into 3 groups and these pigs were reared in metabolism cage. After 10 days adaptation period, N and P balance experiments were carried out for 4 days. The results were summarized as follows ; 1. The High-Ca group was lower than the others in digestibility of P(Low-Ca and Medium-Ca group). 2. The amount of daily excretion of urinary N were 19.6g in Low-Ca group and 16.7g in high-Ca group. The High-Ca group was the lowest(22.71%/d) in the total N excretion. 3. The High-Ca group was the highest and the Low-Ca group the lowest in fecal P excretion. The urinary P excretions per day were 1.90g in Low-Ca group and 0.04g in High-Ca group. The medium-Ca group showed the lowest total P excretion(4.57g/d). 4. The N retention of the High-Ca group(20.50g) was greater than that of the Low-Ca group and Medium-Ca(5.02)g was the highest and the Low-Ca groups(3.92g) was the lowest in the P retention. These results indicate that dietary Ca level was an important factor influencing N and P utilization in pigs.

  • The influence of carrier solutions on particle retention was studied by varying surfactants and ionic strength in flow field-flow fractionation. Experiments were made with five different submicron polystyrene latex standards at three different types of surfactants and seven different ionic strengths. Departures in particle retention from the general theory were observed. At low ionic strength, it is shown that migrating sample zone is clearly lifted away from the ideal equilibrium height and that the repulsive interaction dominates between the particle and the channel wall. As ionic strength increases up to a certain level, particle retention becomes closer to the general theory. Further increase in ionic strength is shown to prolong the retention. An optimum regime of ionic strength is also suggested with the proper choice of surfactants.

  • Thirty six barrows with an initial body weight of 28 kg were used to determine the effect of two dietary Se sources and a wide range of Se levels encompassing 0.3, 1.0, 3.0, 5.0, 7.0, and 10.0 mg/kg Se. The organic Se form was a Se-enriched yeast product, whereas the inorganic Se source was sodium selenite. The experiment was a $2{\times}6$ RCB design conducted in three replicates. Each barrow was placed in an individual metabolism crate and provided their dietary treatment and water on an ad libitum basis for a minimum 2 wk period, whereupon feed intake was adjusted to a constant intake within replicate at approximately 90% of intake for a 4 d adjustment period. Urine and feces were subsequently collected for a 7 d period and analyzed for Se and minerals. The results demonstrated that urinary Se was approximately 25% higher when pigs were fed sodium selenite (p<0.01), whereas fecal Se was lower by 25% (p<0.01). Se retention tended to be higher when organic Se was provided (p>0.15). Urinary Se increased as dietary Se level increased for both Se sources but increased more and at a high rate when sodium selenite was fed resulting in an interaction response (p<0.01). Fecal Se increased linearly as the dietary level of both Se sources increased, but the fecal Se from organic Se increased at a faster rate resulting in an interaction response (p<0.01). Se retention increased linearly (p<0.01) as dietary Se increased for both Se sources. The apparent digestibility of Se increased by Se level when pigs were fed sodium selenite, but not when the organic Se source was provided resulting in an interaction response (p<0.05). Retention of consumed Ca, Zn increased when pigs were fed organic Se (p<0.05) whereas P and Na retention were higher when the inorganic Se was provided. Mineral retention was not affected by dietary Se level except P. These results suggest that Se excretion by urine was the main route of excretion when pigs were fed sodium selenite but the fecal route when Se-enriched yeast was provided. The excretion of Fe, Zn, Mn, and Cu via urine and feces was not affected by high dietary Se level or dietary Se sources.

  • Effect of modified atmosphere packaging conditions on quality changes of dry jujube was investigated. Dry jujubes with moisture content of 26.7% were packaged in PET/Al/PE film pouches with modified atmospheres. The tested packages include those with normal air, vacuum, CO2 flushing, N2 flushing and O2 scavenger. Packages were stored at 25$^{\circ}C$ for 6 months, during which ascorbic acid concentration, browning level, titratable acidity and surface color were measured. Generally modified atmosphere packages could improve quality retention of dry jujubes except that vacuum package resulted in large surface color change. CO2-flushed package showed the best quality retention of high ascorbic acid content and low browning during 112 days, but caused high amounts of ascorbic acid destruction and browning in longer storage. In all the modified atmosphere packages titratable acidity reached a maximum followed by decline and subsequent rise, while it increased linearly with time in normal air package. Considering ascorbic acid retention browning level and surface color changes during 112 days, the packages of CO2 flushing and N2 flushing were better than others.

  • This study empirically examines the synergy effect of a corporate-level loyalty program on customer equity (CE) known as the lifetime value of current and future customers (Blattberg et al. 2009). A corporate-level loyalty program refers to a company-wide integration loyalty program at the corporate-level in which subsidiaries (multi-divisions) participate as program members. It does not merely examine whether there is an integration effect of a corporate-level loyalty program from the CE perspective, but it provides practical implications for a firm's strategic focus by identifying which value creation channels (i.e., acquisition, retention, and cross-selling), brand characteristics (i.e., size of the customer base before integration, diversity of products, and sales channel type), and consumer characteristics (i.e., customer relationship stage, transaction amount before integration, transaction period, and number of purchased brands) are affected the most by the synergy effect.
