Effect of root-knot nematode (Meloidigyne sp.) 1 infection on the growth and quantity of the inorganic substances in 6 year-old ginseng (Panax ginseng C.A. Meyer) was investigated. Naturally infected 6 year-old ginseng roots were grouped into 3 such as healthy, moderate, and heavy according to the degree of the nematode infection. The roots were sampled in the middle of October, 1980 for chemical analysis. Growth of roots in terms of fresh weight, dry weight, length and diameter was greatly reduced by the nematode infection. The content of inorganic substances was different among the various parts of ginseng roots and according to gall index. Phosphorous and nitrogen contents of the healthy ginseng roots were tend to higher than those of the infected ones, whereas calcium was high in infected roots in the order of heavy, moderate, and healthy. Content of the other inorganic substances was highest in the moderately infected roots, and lowest in the heavy one.

This study examined the effect of waiting in a service queue on the evaluation of service quality focused on its overall process, mediators and moderators The conceptual model of this paper integrates key variables derived from previous studies of consumer waiting behavior. Data obtained from actual customers in service queue at a hospital was used to test the theoretical framework. First, results from the path analysis confirm that negative affect and acceptability of the wait function as mediators in the process that the perceived duration of the wait affects customer's evaluation of overall service quality. Second, the analysis of the data, with the use of moderate regression shows that disconfirmation of wait time expectations, transaction importance, stability of wait time and wait environment work as moderate variables for the relationship between perceived duration of wait and negative affect. For the relationship between perceived wait time and acceptability of the wait, on the other hand, only transaction import ante shows a significant effect as a moderator.

The COVID-19 pandemic has ushered in a new era of untact and we are quickly adapting to this untact era. In the current situation where it is difficult to contact each other face-to-face, Virtual Reality (VR) is an opportunity factor for indirect tourism and a good alternative to viewing cultural heritage. This study showed that the effects of experience economies such as entertainment experience, aesthetic experience, escapist experience, and spiritual experience on VR content satisfaction. Furthermore, we examined whether consumers' perceived risks to COVID-19 moderate the relationship between experience economy and satisfaction. This study investigated 149 people who experienced VR content about Jerusalem. The results have shown that entertainment experience and aesthetic experience have a positive effect on the satisfaction with the VR content. Furthermore, perceived risks about COVID-19 have been shown to moderate the effects of aesthetic experience and spiritual experience on satisfaction. Finally, we provided implications based on our findings.

This study investigates whether foreign investors' behavior is involved in firm-specific investor sentiment. Because the mixed role of foreign investors on investor sentiment formation seems to exist in the Korean stock market, it needs to examine the moderate or incremental effect of foreign investors on the stock price crash risk which is due to investor sentiment. The analysis results using Korea Stock Exchanges - listed firms for the period of 2011-2019 show the increased future stock price crash risk which is attributable to high investor sentiment is mitigated for firms with the high foreign ownership, indicating the moderate effect. This study expands the literature on the foreign investors' behavior in the Korean stock market, by showing foreign investors are not involved in firm-specific investor sentiment, which improves market's efficiency in the Korean stock market. Also, the paper is valuable to the academic and practice field in that the findings shed light on the foreign investors' mitigating role in stock price crashes in the behavioral finance perspective.

Background: Fearful and anxious patients who find dental treatment intolerable without sedative and analgesic support may benefit from moderate sedation. Target controlled infusion (TCI) pumps are superior to bolus injection in maintaining low plasma and effect-site concentration variability, resulting in stable, steady-state drug concentrations. We evaluated the safety and efficacy of moderate sedation with remifentanil and propofol using TCI pumps in non-hospital dental settings. Methods: A prospective chart review was conducted on 101 patients sedated with propofol and remifentanil using TCI pumps. The charts were completed at two oral surgeons and one general dentist's office over 6 months. Hypoxia, hypotension, bradycardia, and over-sedation were considered adverse events and were collected using Tracking and Reporting Outcomes of Procedural Sedation (TROOPS). Furthermore, patient recovery time, sedation length, drug dose, and patient satisfaction questionnaires were used to measure sedation effectiveness. Results: Of the 101 reviewed sedation charts, 54 were of men, and 47 were of women. The mean age of the patients was 40.5 ±18.7 years, and their mean BMI was 25.6 ± 4.4. The patients did not experience hypoxia, bradycardia, and hypotension during the 4694 min of sedation. The average minimum Mean Arterial Pressure (MAP) and heartbeats were 75.1 mmHg and 60.4 bpm, respectively. 98% of patients agreed that the sedation technique met their needs in reducing their anxiety, and 99% agreed that they were satisfied with the sedation 24 hours later. The average sedation time was 46.9 ± 55.6 min, and the average recovery time was 12.4 ± 4.4 min. Remifentanil and propofol had mean initial effect-site concentration doses of 0.96 µ/.ml and 1.0 ng/ml respectively. The overall total amount of drug administered was significantly higher in longer sedation procedures compared to shorter ones, while the infusion rate decreased as the procedural stimulus decreased. Conclusion: According to the results of this study, no patients experienced adverse events during sedation, and all patients were kept at a moderate sedation level for a wide range of sedation times and differing procedures. The results showed that TCI pumps are safe and effective for administering propofol and remifentanil for moderate sedation in dentistry.

Object: This study investigated the effect of self-esteem on depression through family relations satisfaction and tested whether working types would moderate such associations. Method: The subjects were 2,145 elderly who are healthy enough to work and were selected for the ninth Korean Welfare Panel Study. The resulting data were analysed by using the statistical program SPSS 2.1 with reference to steps for testing mediation by Baron and Kenny, moderated mediation by Heyes. Results: Self-esteem has both direct and indirect significant effects, revealing that family relations satisfaction fully mediates the effects of coping strategies of family conflict on depression. From the working types, self-employed/employer and unpaid family worker, moderate the indirect effect of self-esteem on depression through family relations satisfaction. Conclusions: In practical intervention of elderly depression reduction, efforts to increase family relations satisfaction is effective when it is difficult to us address satisfaction. Moreover, we have to provide intervention for elderly with work in context of relationship of individual and familial factor.

Objective: This study aimed to investigate the effect of micro-osteoperforations (MOPs) on external apical root resorption (EARR) during the initial orthodontic alignment phase of maxillary anterior crowding. Methods: Thirty patients (25 females, 5 males; mean age, 22.66 ± 3.27 years) who presented with moderate crowding of the upper labial segment and underwent extraction-based fixed appliance treatment were recruited. They were randomly allocated to receive adjunctive therapy with MOPs (n = 15) or treatment with fixed appliances only (control group; n = 15). EARR was measured from long-cone periapical radiographs taken at the start and the sixth month of treatment. A correction factor for the enlargement difference was used to calculate EARR. Data were analyzed with descriptive statistics and repeated-measures analysis of variance. Results: The mean root lengths of 168 teeth were measured and showed no statistically significant difference (p > 0.05) after six months of fixed appliance treatment in the MOP (mean difference [MD] = 0.13 mm; 95% confidence interval [CI] = -0.10-0.35) and control group (MD = 0.14 mm; 95% CI = -0.10-0.37). Most of the roots in the MOP and control groups (42.86% and 52.38%, respectively) showed only mild resorption. Less than 8% of the roots in both groups (7.14% in the MOP group and 4.76% in the control group) showed moderate resorption. Conclusions: Acceleration of orthodontic tooth movement with adjunctive MOPs therapy during the alignment phase does not exacerbate EARR in patients with moderate crowding of the upper labial segment in comparison with controls.
