Purpose: This study systematically examined the concept of digital selling readiness of salespeople. Additionally, this study empirically confirms the sequential mediating roles of digital literacy and salesperson self-efficacy in the impact of digital selling readiness on customer-oriented behavior. Research design, data, and methodology: We collected data from salespeople at a Bank and Financial Service firm in South Korea. A total of 254 salespeople were invited to participate, with 154 surveys returned. After removing the questionnaires with missing values, 150 complete surveys were employed for the analysis. Results: The empirical analysis indicates that digital selling readiness positively affects digital literacy. Digital literacy, in turn, is positively associated with self-efficacy, leading to increased customer-oriented behaviors among salespersons. This study also confirms the sequential mediating effects of digital literacy and self-efficacy in the impact of salespeople's digital selling readiness on customer-oriented behavior. Conclusions: Our research deepens the understanding of how digital selling readiness fosters customer-oriented behavior through the sequential mediating effects of digital literacy and self-efficacy. This study extends the previous model by sequentially involving digital literacy and self-efficacy to better understand the psychological processes of digital selling. The results highlight the role of digital selling readiness in preparing salespeople for digital sales.

This study examined the effects of perceived discrimination on multicultural adolescents regarding feelings of This study examined the direct effect of socially prescribed perfectionism on interpersonal anxiety in upper elementary school students and the sequential mediating effect of dichotomous thinking and rejection sensitivity on this relationship. The sample comprised 306 upper elementary school students (grades 4 to 6; 149 boys, 48.7%) in Seoul, Incheon, and Busan. The Data were collected through an online self-report questionnaire completed by the participants and analyzed using SPSS version 27.0 and MPlus version 8.7 software. The analyses revealed three key findings. First the direct effect of socially prescribed perfectionism on interpersonal anxiety was not statistically significant. Second dichotomous thinking mediated the relationship between socially prescribed perfectionism and interpersonal anxiety, whereas rejection sensitivity did not. Finally, socially prescribed perfectionism influenced interpersonal anxiety through the sequential mediation of dichotomous thinking and rejection sensitivity. In conclusion, although socially prescribed perfectionism does not directly influence interpersonal anxiety, children may experience interpersonal anxiety in situations involving dichotomous thinking due to socially prescribed perfectionism, leading to rejection sensitivity. These findings suggest that interventions for interpersonal anxiety in upper elementary school students should focus on psychological problems attributed to socially prescribed perfectionism.

Objective: To evaluate the effect of clear aligner treatment and differential sequence distalization of maxillary posterior teeth on anchorage loss in the upper incisors (U1s). Methods: This study used lateral cephalometries and digital models of 12 patients treated with 33% sequential distalization (group 1, mean age: 22.9 ± 0.7 years, five males, seven females) and 12 treated with 50% sequential distalization (group 2, mean age: 25.83 ± 0.5 years, three males, nine females) acquired before and after distalization of upper second premolars (U5) and upper first molars (U6) and upper second molars (U7). The amount of distalization was determined as 2.5 mm in both the groups. Independent Samples t test was used to compare normally distributed parameters. Mann-Whitney U and Wilcoxon tests were used to compare parameters that were not normally distributed. Results: In both groups, the posterior teeth significantly moved by tipping distally and the U1s were displaced anteriorly. Increase in maxillary posterior transverse width (P < 0.001) and distopalatal rotation were observed in U5, U6, and U7 after distalization. It was also observed that U1 was significantly more proclined (1.82°; P < 0.001) and protruded (0.62 mm; P < 0.001), and the overjet (0.45 mm; P < 0.001) increased more in group 1 than in group 2. Conclusions: After sequential distalization of maxillary posterior teeth, more anchorage loss was observed in the anterior region in group 1 than in group 2.

The current paper was conducted to unravel the influence of affect induction as a background emotion in the process of cognitive task to judge the degree of sequence in groups with or without anxiety symptoms. Four types of affect induction and two sequential task types were used as within-subject variables, and two types of college students groups classified under the Beck Anxiety Inventory (BAI) as a between-subject variable were selected to determine reaction times involving sequential judgment among the lexical relevance information. DmDx5 was used to present a series of stimuli and elicit a response from subjects. Repeated measured ANOVA analyses revealed that reaction times and error rates were significantly larger with anxiety participants compared to the normal group regardless of affect and task types. Within-subject variable effects found that specific affect type (sorrow condition) and number-related task type showed a more rapid response compared to other affect types and magnitude-related task type, respectively. In sum, these findings confirmed the difference in tendency with reaction time and error rates that varied as a function of accompanying affect types as well as anxiety level and task types suggesting the that underlying background affect plays a major role in processing affect-cognitive association tasks.

The objective of this study was to evaluate the effects of sequential applications of ${\varepsilon}$-polylysine (EPL) or lauramide arginine ethyl ester (LAE) sprays followed by an acidic calcium sulfate (ACS) spray on inoculated chicken carcasses to reduce Salmonella (Salmonella enterica serovars including Salmonella typhimurium and Salmonella enteritidis) contamination during 6 days of storage ($4.4^{\circ}C$). Secondly, reductions of the resident microflora were studied on uninoculated chicken carcasses following the sequential application of the treatments, chilling and 10 days of storage at $4.4^{\circ}C$. The treatment of Salmonella inoculated carcasses with 300 mg/L EPL followed by 30% ACS (EPL300-ACS30) sprays reduced Salmonella counts initially by 1.5 log cfu/mL and then by 1.2 log cfu/mL (p<0.05) following 6 days of storage at $4.4^{\circ}C$. Likewise, 200 mg/L LAE followed by 30% ACS (LAE200-ACS30) treatment reduced initial Salmonella counts on poultry carcasses by 1.8, 1.4 and 1.8 log cfu/mL (p<0.05), respectively, after 0, 3, and 6 days storage. Immediately after the treatments, EPL300-ACS30 and LAE200-ACS30 both reduced Escherichia coli counts significantly by 2.6 and 2.9 log cfu/mL, respectively. EPL300-ACS30 and LAE200-ASC30 were effective in lowering psychrotroph counts by 1 log cfu/mL on day 10 when compared to the control and distilled water treatments. This study demonstrated that EPL300-ACS30 and LAE200-ACS30 were effective in reducing Salmonella on inoculated chicken carcasses both after treatment and during the storage at $4.4^{\circ}C$ for up to 6 days. In addition, reductions in psychrotroph counts indicated that these treatments might have the potential to increase the shelf-life of poultry carcasses.

The purpose of this retrospective study was to evaluate the effects of diagnostic sonography in pediatric patients with inguinal hernias. The patients were classified into two groups. Group A included the patients who had been operated upon for inguinal hernia in 1980's, when diagnostic sonography was not available. Group B included the patients, operated upon for inguinal hernia from 2001 to 2002, when inguinal sonography was employed to detect potential bilateral hernias. The age distribution, sex ratio, laterality, bilaterality, and concomitant symptoms were compared between group A and group B. There were 296 cases in group A and 377 cases in group B. The prevalent age group was from 1 to 5 years. There was no difference in age group distribution between both groups. The male to female ratio was 5.3:1 in group A and 3.5:1 in group B. The ratio of unilateral to bilateral hernia was 5:1 in group A and 3:1 in group B. In cases with a unilateral hernia, the ratio of right to left was 1.5:1 in group A and 1.8:1 in group B. In cases with bilateral hernia, the simultaneous bilateral hernia was 33 cases (67.4 %) in group A and 75 cases (80.6 %) in group B. The sequential bilateral hernia was 16 cases (32.7 %) in group A and 18 cases (19.4 %) in group B. Although the ratio of bilateral hernia was increased in group B, the portion of the sequential bilateral hernia was significantly decreased in group B. In conclusion, there were no differences in the age distribution and the laterality between group A and B. The ratio of female patients and the incidence of bilateral hernia were increased in group B even though the portion of the sequential bilateral hernia was decreased. This result shows that the preoperative inguinal sonography in unilateral hernia with potential bilateral hernia is useful in early detection of the sequential contralateral hernia.

This study proposes a new method of multiple homographies estimation between two images. With a large proportion of outliers, RANSAC is a general and very successful robust parameter estimator. However it is limited by the assumption that a single model acounts for all of the data inliers. Therefore, it has been suggested to sequentially apply RANSAC to estimate multiple 2D projective transformations. In this case, because outliers stay in the correspondence data set through the estimation process sequentially, it tends to progress slowly for all models. And, it is difficult to parallelize the sequential process due to the estimation order by the number of inliers for each model. We introduce a guided sequential RANSAC algorithm, using the local model instances that have been obtained from RANSAC procedure, which is able to reduce the number of random samples and deal simultaneously with multiple models.

The final goal for an orthognathic surgery is a functional and esthetic achievement based on occlusion theory. All the dental treatment should be done with the occlusion in mind, though, they tend to be ignored with no good reason. We cannot think of occlusion without temporomandibular joint because it is the first clue to define an occlusion. As normal occlusion comes from the central tendency of distribution of population, we can get it by examining the population that closely meet the criteria of ideal occlusion. To perform proper occlusal function and to maintain the stability after treatment, the case must be finished in normal occlusion closer to ideal one. Our aim is to achieve the ideal occlusal scheme like the mutually protected occlusion with the best masticatory efficiency and the stability. The facial esthetics are influened by culture, race and the time in which human live. While the occlusal function rarely changes as time goes by, esthetics tend to do from one country to another. Orthodontists and maxillofacial surgeons should have solid sets of treatment goals to achieve the best facial esthetics and the ideal occlusion dictated by the joint. Doing orthognathic surgery, two factors aforementioned should be taken into account to establish the Surgical Treatment Objectives(STO). The doctors who are planning orthognathic surgery need to have a very logical and systematic thought process to make STO. The author examined 28 selected beautiful Korean female adults with normal skeleton with normal occlusion and analyzed the hard and the soft tissue relationship into five parts : dentomaxillary relationship, intermaxillary relationship, posture to hard tissue relationship, facial balance, and posture to soft tissue relationship. This study presents a sequential flow of diagnosis and treatment planning especially for surgical patients and it also can be applied to the nonsurgical patients.

Vitamin D plays a major role in bone metabolism, and its deficiency has an impact on fracture risk and healing. Low vitamin D levels are a cause of poor bone mineralization and have been associated with a significantly higher risk of physeal injury in children. This paper presents a case of a 13-year-old boy with a vitamin D deficiency, who sustained multiple sequential epiphyseal injuries at various areas. This report suggests that vitamin D deficiency is not only a significant cause of the clinical disease itself, but also an important factor affecting the successful recovery of injuries.

This study aims to identify the employment path of vocational instructors using sequential analysis. By grasping the employment path in detail, the study presents implications for implementing support measures for systematic preparation for employment. In particular, the study presents the relationship of the vocational instructor's employment path in stages through frequency analysis, conversion probability analysis, significance test, and conversion status diagram of each employment path. For the analysis, the survey results of the vocational instructors working at private vocational training institutions were used. In conclusion, (i) as for the frequency of past experience for employment as a vocational instructor, the share of work experience, teaching training, and teaching experience was large. (ii) In the employment path stage, work experience, teaching training, and teaching experience had the greatest influence on the transition to the later stage. (iii) The prominent employment path for vocational instructors was "work experience-teaching experience-teaching training." Based on the conclusions, the study proposes a plan for systematic employment of vocational instructors.
