Purpose: This study aims to determine the impact of helicopter parenting and respectful parenting on medical students’ mindset, grit, self-directedness, and college adjustment. Methods: This study constructed a hypothetical model based on the relationship between helicopter parenting, respectful parenting, mindset, grit, self-directedness, and college adjustment. It set up a structural model to test the fit of the model based on empirical data. The significance of the mediating effects of the paths was tested using multiple mediation analysis. Results: The fit of the initial measurement model did not meet the goodness-of-fit acceptance criteria; therefore, revised models were established. The revised models all showed good fit indices, and the overall path coefficients were significant. Helicopter parenting and respectful parenting are inversely correlated and affect the mindset of medical students, which, in turn, affects their adjustment to college through grit and self-directedness. The results of the multimodal effects of each pathway showed that helicopter parenting negatively affects college adjustment, while respectful parenting has a positive mediating effect on college adjustment. Conclusion Parenting attitudes have a significant impact on medical students’ mindset, grit, and self-direction, which affects their college adjustment. Parents need to respect their children’s autonomy and independence and avoid excessive interference.

Carcinoma of the parathyroid gland is rare, comprising only 0.1% to 5% of all patients with primary hyperparathyroidism. It presents with severe hypercalcemia, bone disease, palpable neck mass, renal involvement and etc. Since the initial operation offers the best chance for cure, preoperative localization and intraoperative recognition of parathyroid cancer are essential. Recently parathyroid imaging has been described with 99mTc-sestamibi as an alternative to 201Tl. This newer agent has many physical and dosirnetric advantages and represents higher detection sensitivity than 201Tl-99mTc subtraction scan. We experienced a 41-year-old man presenting with recurrent hyperparathyroidism in spite of 2 previous operations. In preoperative localization, there was no abnormal uptake in 201Tl-99mTc subtraction scan but 99mTc-sestamibi scan revealed metastatic foci on right cervical area. He was successfully treated with modified radical neck dissection.

PURPOSE: There is no established formula for estimating renal depths in Korean. As a result, we undertook this study to develop a new formula, and to apply this formula in the calculation of glomerular filtration rate (GFR). MATERIALS AND METHODS: We measured the renal depth (RD) on the abdominal CT obtained in 300 adults (M:F=167:133, mean age 50.9 years) without known renal diseases. The RDs measured by CT were compared with the estimated RDs based on the Tonnesen and Taylor equations. New formulas were derived from the measured RDs in 200 out of 300 patients based on several variables such as sex, age, weight, and height by multiple regression analysis. The RDs estimated from the new formulas were compared with the measured RDs in the remaining 100 patients as a control. In 48 patients who underwent Tc-99m DTPA renal scintigraphy, GFR was measured with three equations (new formula, Tonnesen and Taylor equations), respectively, and compared with each other. RESULTS: The mean values of the RDs measured from CT were 6.9 cm for right kidney of the men (MRK), 6.7 cm for left kidney of the men (MLK), 6.7 cm for right kidney of the women (WRK), and 6.6 cm for left kidney of the women (WLK). The RDs estimated from Tonnesen equation were shorter than the ones measured from CT significantly. The newly derived formulas were 12.813 (weight/height)+0.002 (age)+ 2.264 for MRK, 15.344 (weight/height)+0.011 (age)+0.557 for MLK, 12.936 (weight/height)+ 0.014 (age)+1.462 for WRK and 13.488 (weight/height)+0.019 (age)+0.762 for WLK. The correlation coefficients of the RD measured from CT and estimated from the new formula were 0.529 in MRK, 0.729 in MLK, 0.601 in WRK, and 0.724 in WLK, respectively. The GFRs from the new formula were significantly higher than those from the Tonnesen equation significantly, which was the most similar to normal GFR values. CONCLUSION: We generated new formulas for estimating RD in Korean from the data by CT. By adopting these formulas, we expect that GFR can be measured by the Gates method accurately in Korean.

PURPOSE: This study compared fracture strength and fracture modes between metal wire reinforcement and glass fiber reinforcement in repaired maxillary complete denture. MATERIALS AND METHODS: In this study, fracture was reproduced on center of maxillary complete dentures and the denture was repaired with auto-polymerizing resin. The experimental groups (n = 10) were subjected to the following condition: without reinforcing material (control group), reinforcing with metal wire (W group), reinforcing with glass fiber pre-impregnated with light-curing resin (SES MESH, INNO Dental Co., Yeoncheon, Korea, G group). The fracture strength and fracture modes of a maxillary complete denture were tested using Instron test machine (Instron Co., Canton, MA, USA) at a 5.0 mm/min crosshead speed. The flexure load was applied to center of denture with a 20 mm diameter ball attachment. When fracture occurred, the fracture mode was classified based on fracture lines. The Kruskal-wallis test and the Mann-whitney U test were performed to identify statistical differences at alpha=.05. RESULTS: W group showed the highest value of fracture strength, there was no significant difference (P>.05) between control group and G group. Control group and W group showed anteroposterior fracture mainly, group W showed adhesive fracture of denture base and reinforcing material. CONCLUSION: In limitation of this study, the glass fiber did not improve the fracture strength of repaired maxillary complete denture, and adhesive failure was occurred along the lines of glass fiber.
