Purpose: This cross-sectional study was carried out to identify factors influencing the health-related quality of life according to socioeconomic level during early adolescence. Methods: Participants were 617 middle school students in $1^{st}$ and $2^{nd}$ grade. All measures were self-administered. Data were analyzed using SPSS 21.0 program and factors affecting the health-related quality of life were analyzed by t-test, ANOVA, Duncan test, Pearson's correlation coefficient, and multiple regression analysis. Results: According to the level of Family Affluence Scale (FAS), 19.1% of the participants were in the high class, 66.5% in the middle class, and 14.4% in the low class. We have found statistically significant differences among the high, middle, and low classes regarding the health-related quality of life, health perception, resourcefulness, family function, and social capital. The most influential factors of the health-related quality of life were found to be resourcefulness, family function, and social capital in the high and the middle class. Conclusion: The implication of this study is that it is important for the Education Ministry and middle school teachers to help adolescents develop internal coping resources as well as to develop school-curriculums considering social values and norms related to social capital in order to improving their health-related quality of life.

After introducing tyrosine kinase inhibitors (TKIs) as promising treatments for radioactive iodine refractory advanced thyroid cancer patients, we more often meet patients with TKI-related hormone and electrolyte imbalances in clinics. Hypocalcemia associated with TKI is associated with an imbalance in calcium-vitamin D metabolism. TKI-related hypothyroidism is related to the metabolic rate of thyroid hormones. The two side effects usually occur in the early stages of TKI treatment, and if the imbalance is corrected appropriately, the effects are minor, but in severe cases, the TKI should be discontinued. The authors reported a case of severe hypocalcemia and thyroid dysfunction after TKI treatment. A 56-year-old man suffered from symptomatic hypocalcemia during TKI treatment, which was resolved after he stopped taking the TKI medication. Although calcium and vitamin D replacement have increased, hypocalcemia was recurred and TKI treatments have been permanently stopped due to serious weight loss in grade 3. After the interruption, his calcium levels normalized.
This paper dealt with a statistical analysis for evaluating the creep crack growth rate (CCGR) for Modified 9Cr-1Mo (ASTM Grade 91) steel. The CCGR data was obtained by the creep crack growth (CCG) tests conducted under various applied loads at $600^{\circ}C$. To obtain logically the B and q values used in the CCGR equation, three methods such as the least square fitting method (LSFM), the mean value method (MVM) and the probabilistic distribution method (PDM) were adopted and their CCGR lines were compared, respectively. In addition, a number of random variables were generated by using the Monte Carlo simulation (MCS), and the CCGR lines were predicted probabilistically. It was found that both the B and q coefficients followed a 2-parameter Weibull distribution well. In the case of the ranges of 10-90% for the probability variables, P(B, q), the CCGR lines were predicted. Fractographic study was conducted from the specimen after the CCG tests.
Purpose: This study aims to identify gender-based differences in factors related to smartphone overdependence among middle school students. Methods: The subjects of the study were middle school students who participated in the 16th Korea Youth Risk Behavior Survey (2020). Frequency analysis, the Rao-Scott χ2 test, and multiple logistic regression were performed using SPSS 27.0. Results: Identified risk factors were grade level, self-reported health, self-reported happiness, loneliness, smoking, drinking, poor sleep quality, physical activity, and generalized anxiety disorder, which were commonly found in all participants. Additionally, stress was found related only in boys, while the residential area and depression showed associations only in girls. In particular, the more severe was the level of generalized anxiety disorder, the higher was the risk ratio of the high-risk group, compared to the potential-risk group. Conclusion: Based on the findings of the study, a customized strategy that considers gender differences should be developed in order to prevent smartphone overdependence in middle school students.

This study aimed to analyse the initial results of five patients with symptomatic osteochondral lesions (OCL) and femoroacetabular impingement (FAI) who were treated successfully with osteochondral autologous transfer (OAT) and femoral neck osteochondroplasty (OCP) through surgical dislocation of the hip. Five patients with FAI and OCL of the femoral head who underwent surgery between 2015-2018 were studied retrospectively. All patients had a grade IV OCL, and the median defect size was 2 cm2 (interquartile range [IQR], 2-2). At the final follow-up, the modified Harris hip score showed a median value of 94 (IQR, 91-95) (P=0.04). Pain evaluation using the visual analogue scale showed a median value of 1 (IQR, 1-2) (P=0.04). Adequate graft union and healthy formation of the chondral surface were observed by magnetic resonance imaging. Although the procedure is demanding, the combination of OAT and femoral neck OCP appears to be an effective alternative in young patients.

Objectives: Hypertension is the most important risk factors for the cerebrovascular diseases, and also for coronary heart diseases, it is therefore very important that the people have a knowledge on nature of hypertension and it's high risk in order to prevent and detect the hypertension as early as possible. Methods: This study was done to find out the knowledge on hypertension of 434 parents of elementary school students from Kimjae city, Jonbuk province, they were parents in grade 4, 5 and 6 attending two elementary schools. The survey took 10 days from November 20 to November 30, 2003. Results: first, The highest correct answer(94.5%) was "obesity is risk factors for hypertension", followed by "hypertension is closely related with hereditary factors(91.0%) and "high sodium intake is associated with high blood pressure"(85.7%). The lowest correct answer(77.4%) was the classification of blood pressure level between normal and high. Second, Rate of blood pressure measurement for fathers was 53.7% and 54.8% in mothers. Awareness of own blood pressure by fathers was 84.1 %, while 91.1% by mothers. Third, According to blood pressure level reported by parents, fathers with normal blood pressure was 59.2%, high normal blood pressure was 12.2%, while hypertension was 28.6%. It revealed that prevalence of hypertension of fathers was higher than mother (normal: 74.5%, high normal: 7.7%, hypertension: 18.2%). Conclusions: From the results of this study, it is important to strengthen the health education about hypertension for community people and also school students.
Purpose: This analysis was to compare the result of radiation alone and chemoradiation in cervical cancer in terms of response, survival, failure, and complication. Materials and Methods: A retrospective analysis of 135 cervical cancer patients treated with definitive radiotherapy from November 1985 to December 1991 was performed. Fifty-six patients were treated with radiation alone and 79 patients were treated with cisplatin-based chemotherapy plus radiation. Follow-up period ranged from 5 to 105 months with a median 47 months. According to the FIGO classification, the patients were subdivided into 18 $(13.3\%)$ stage IB, 7 $(5.2\%)$ stage IIA, 97 $(71.9\%)$ stage IIB, and 9 $(6.7\%)$ stage IIIB. Results: A complete response was noted in 51 patients $(91.1\%)$ of the radiation alone group, and 68 patients $(86.1\%)$ of the chemoradiation group. There was no statistical difference in complete response rate between the two groups. Overall survival rate at 5 years was $73.3\%$. According to stage, overall survival rates at 5 years were $88.9\%$ in stage IB, $85.7\%$ in stage IIA, $73.8\%$ in stage IIB, and $37.5\%$ in stage IIIB, respectively. According to treatment modality, overall survival rates at 5 years were $81.9\%$ in the radiation alone group, $67.0\%$ in the chemoradiation group (p=0.22). Disease-free survival rate at 5 years were $70.4\%$ in the radiation alone group. $68.5\%$ in the chemoradiation group (p=0.85) Locoregional control rates at 5 years were $76.1\%$ in the radiation alone group, $73.8\%$ In the chemoradiation group (p=0.70). Distant disease-free survival rates at 5 years were $83.9\%$ in the radiation alone group, $90.3\%$ in the chemoradiation group (p=0.59). Treatment-related bone marrow suppressions were noted in 3 $(5.4\%)$ patients of the radiation alone group, 14 patients $(17.7\%)$ of the chemoradiation group (p(0.05). Grade 2 vesical complications were noted in 14 patients of the radiation alone group. and 10 Patients of the chemoradiation group. Grade 2 rectal complications were noted in 2 patients of the radiation alone group, and 3 Patients of the chemoradiation group. One case of rectal perforation was noted in the chemoradiation group, and grade 2 small bowel obstructions were noted in 2 patients of the radiation alone group. There were no statistical differences in the incidence of vesicar, rectal, and small bowel complicaions between the two groups. Conclusion: No statistical difference was found between the radiation alone group and the chemoradiation group in terms of response, survival, and failure. but the incidence of bone marrow suppression was higher in the chemoradiation group.
Background: Despite the excellent early results after the repair of congenital bicuspid aortic valve (BAV) disease, the mid-term durability of the repaired valve has still controversies. Material and Method: To evaluate the mid-term results of BAV repair, retrospective review of medical records and echocardiographic data were done. Between 1994 and 2003, twenty-two patients underwent reparative procedure for either regurgitant or stenotic congenital bicuspid aortic valve (BAV). Result: Mean age was $41\pm14$ years with male predominance (Male=17, Female=5). The pathophysiologies of the BAV were regurgitation-dominant in 20 (91%) and stenosis-dominant in 2 (9%) cases. Various repair techniques were used for raphe, prolapsed leaflet, thickened leaflet, and commissures; 1) release of raphe in 19 (86%), 2) wedge resection and primary repair in 11 (50%), pericardial patch reinforcement after plication of the leaflet in 6 (27%), and plication of the leaflet in 3 (14%), 3) slicing of thickened leaflet was used in 12 (55%) cases, 4) commissuroplasty in 8 (36%), and commissurotomy in 6 (27%) cases. There was no in-hospital mortality. During the mean follow-up of $38\pm17$ months, one patient underwent aortic valve replacement after developing acute severe regurgitation from dehiscence of the suture on postoperative 2 months. New York Heart Association functional class was improved from $1.9\pm0.6$ to $1.2\pm0.5$ (p<0.01). Left ventricular end-systolic and diastolic dimension (LVESD/LVEDD) were also improved from $45\pm9$ and $67\pm10$ to $37\pm10$ and $56\pm10,$ respectively (p<0.01). The grade of aortic regurgitation (AR) was improved from preoperative $(3.1\pm1.2)$ to post-bypass $(0.9\pm0.7).$ However, the grade at last follow-up $(1.7\pm1.1)$ was deteriorated during the follow-up period (p<0.01). Freedom from grade III and more AR at one, three, and four year were 89.7%, 89.7%, and 39.9% respectively. Conclusion: Midterm clinical result of the BAV repair was favorable. But, the durability of the repaired valve was not satisfactory.
[ $\underline{Purpose}$ ]: To evaluate the outcome and prognostic factors of postoperative radiotherapy in endometrial carcinoma. $\underline{Materials\;and\;Methods}$: From September 1991 to August 2003, 76 patients with endometrial carcinoma received postoperative adjuvant radiotherapy after hysterectomy at Asan Medical Center. Stage was classified as FIGO I in 41 (53.9%), II in 12 (53.9%), and III in 23 (30.3%). Histologic grade 1, 2 and 3 were in 29 (38.2%), 20 (26.3%), and 27 (35.5%) respectively. Forty two patients received both external beam radiation therapy (EBRT) and intracavitary radiation (ICR), 34 patients were treated with EBRT or ICR alone. EBRT dose was 50.4 Gy, ICR was performed in $4{\sim}6$ fractions with $4{\sim}5\;Gy$ per fraction. Median follow-up period was 51 (range $5{\sim}121$) months. $\underline{Results}$: Five-year overall survival was 89.6%. In univariate analysis, statistically significant factors to overall survival were FIGO stage, lymph node metastasis and histologic grade. In disease free survival, FIGO stage, lymph node metastasis and lymphovascular invasion were significant prognostic factors. Recurrence was seen in 11 patients. Of these, systemic failure was in 10 patients. There were no moderate to severe complications after radiation therapy. $\underline{Conclusion}$: The outcome of postoperative adjuvant radiotherapy in endometrial carcinoma was good. Main pattern of failure after postoperative radiotherapy was distant metastasis. So, adjuvant chemotherapy may help in improving outcome. Further study on chemotherapy in combined with postoperative radiotherapy will be needed, especially for patients with high risk factors such as high FIGO stage, lymphovascular invasion, and high histologic grade.
Background: Mitral valve repair rather than replacement for mitral regurgitation (MR) offers a number of well-accepted benefits. However, the surgical results of repair for mitral valve endocarditis remain largely unknown. Material and Method: Fourteen patients who underwent mitral valve repair for MR caused by mitral valve endocarditis from April 1995 through October 2001 were reviewed retrospectively. There were 9 male patients and mean age was 32$\pm$10 years. Four patients had previous embolism and 2 had active infections. The grade of MR were III in 6 patients and IV in 8. Operatively, mitral annuloplasty was performed in 12 patients and various valvuloplasty techniques were applied in all patients. One patient had immediate valve replacement due to residual MR after weaning of cardiopulmonary bypass. Result: There was no early operative death. Early postoperative transthoracic echocardiography revealed no or grade I of MR and no or mild mitral stenosis in 13 patients. After the mean follow-up of 36 months, there was no late death, and no or grade I of MR in 11 patients (84.6%) and no or mild mitral stenosis in 12 patients (92.3%). Reoperation required in one patient (7.1%). The cumulative freedom from recurrent MR and valve-related reoperation at 5 years were 91$\pm$9% and 75$\pm$22%, respectively. Conclusion: This study suggests that mitral valve repair for mitral regurgitation caused by endocarditis offers good early and intermediate survival and functional improvement without reinfection, and it is an attractive alternative to valve replacement in selective patients with bacterial endocariditis.
