Purpose: This study conducted a concept analysis of rejection sensitivity using the Walker and Avant method, to clarify its defining attributes, antecedents, and consequences. So, this contributes to a deeper understanding of its role in interpersonal relationships. Methods: Walker and Avant’s framework, this concept analysis included a thorough literature review across multiple disciplines. The literature was extracted from databases such as PubMed, Web of Science, CINAHL, and RISS. Results: Rejection sensitivity is a psychological construct encompassing several attributes, including rejection expectation, perception of rejection, and reaction to perceived rejection. This trait is influenced by various antecedents, including early life experiences, attachment style, and cultural factors. The consequences or events associated with rejection sensitivity span multiple domains and can significantly affect an individual’s life. Conclusion According to interpersonal psychology and attachment theory, problem behavior in adolescents is a state of unsatisfied affection for parents and a response to feelings of unacceptance. Rejection sensitivity is particularly important in the Korean culture because of cultural factors.

Almost all colorectal carcinomas have been thought to develop from pre-existing adenomas. However, some colorectal carcinomas can arise directly from normal flat mucosa, and usually form infiltrative mass at the early stage. The carcinogenesis of this infiltrative carcinoma may be different from the well-known adenoma-carcinoma sequence, which usually forms a polypoid mass. The purpose of this study is to investigate the different expression of various oncogenes in polypoid carcinoma and infiltrative carcinoma. We performed immunohistochemical staining on p53, bcl-2, c-erbB-2 and MIB-1 in 29 polypoid carcinomas arised from adenomas, and 21 infiltrative carcinomas. The average tumor size of infiltrative carcinomas (5.5 cm) was larger than that of polypoid carcinomas (3.1 cm), and the polypoid carcinomas were differentiated more than the infiltrative carcinomas. The results of p53, bcl-2, c-erbB-2, and MIB-1 antisera immunoreactivity in the polypoid carcinoma were 79%, 17%, 21%, and 100%, and those in the infiltrative carcinoma were 71%, 29%, 29%, and 100%, respectively. However the diffuse positivities of p53 and MIB-1 antisera were slightly higher in the infiltraive carcinomas (62%, 76%) than in the polypoid carcinomas (55%, 41%) (p=0.63, 0.01). And the results of p53 and c-erbB-2 immunoreactivity in the adenomas were 52% and 17%, respectively, which is significantly lower than that in the polypoid carcinoma(p=0.03, 0.74). The immunoreactivty of bcl-2 in the adenoma was 72%, which was significantly higher than that in the polypoid carcinoma (17%) (p<0.01). In summary, we did not show the significant difference in expression of p53, bcl-2, c-erbB-2, and MIB-1 proteins between polypoid and infiltrative carcinomas. However, the tendency of infiltrative carcinomas having a more aggressive nature suggests another carcinogenetic mechanism is involved in the colorectal carcinogenesis.

OBJECTIVES: This study explored socioeconomic disparities in Korea using health insurance type as a proxy during the ongoing coronavirus disease 2019 (COVID-19) pandemic. METHODS: We conducted a retrospective cohort study using Korea’s nationwide healthcare database, which contained all individuals who received a diagnostic test for COVID-19 (n=232,390) as of May 15, 2020. We classified our cohort by health insurance type into beneficiaries of the National Health Insurance (NHI) or Medicaid programs. Our study outcomes were infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and COVID-19-related outcomes, a composite of all-cause death, intensive care unit admission, and mechanical ventilation use. We estimated age-, sex-, and Charlson comorbidity index score–adjusted odds ratios (aORs) with 95% confidence intervals (CIs) using a multivariable logistic regression analysis. RESULTS: Of the 218,070 NHI and 14,320 Medicaid beneficiaries who received COVID-19 tests, 7,777 and 738 tested positive, respectively. The Medicaid beneficiaries were older (mean age, 57.5 vs. 47.8 years), more likely to be males (47.2 vs. 40.2%), and had a higher comorbidity burden (mean CCI, 2.0 vs. 1.7) than NHI beneficiaries. Compared to NHI beneficiaries, Medicaid beneficiaries had a 22% increased risk of SARS-CoV-2 infection (aOR, 1.22; 95% CI, 1.09 to 1.38), but had no significantly elevated risk of COVID-19-related outcomes (aOR 1.10, 95% CI 0.77 to 1.57); the individual events of the composite outcome yielded similar findings. CONCLUSIONS As socioeconomic factors, with health insurance as a proxy, could serve as determinants during the current pandemic, pre-emptive support is needed for high-risk groups to slow its spread.

A case of right-sided infective endocarditis in a 22-year-old male with ventricular septal defect of perimembranous type, right ventricular(RV) infundibular and pulmonic valve stenosis was reported. The vegetations were found on the mural endocardium of RV infundibulum and pulmonic valve. Streptococcus viridans was identified in 5 consecutive blood cultures, Pulmonary embolism and septic infarction in the lung was associated with systemic embolization, which was manifested by left renal infarction. The RV infundibular stenosis was due to anomalous muscle bundle at the proximal portion. Therefore, we thought that the mechanism of RV infundibular vegetation was probably due to 'Venturi effect and turbulence'. Several clinical features which were found in this case were also reviewed.

OBJECTIVE: The aim of this study was to assess the relationship between disease progression and expression of c-erbB-2 and S-100 protein positive dendritic cells in Cervical cancer. STUDY DESIGN: Tissues were analyzed from 100 patients. Each of them had invasive carcinoma(44), microinvasive(12), CIS(33), CIN(II) before treatment, c-erbB-2 oncoprotein expression and S-100 protein positive dendritic cell were confirmed by immunohistochemical staining. (Avidin-biotin complex method) RESULTS: C-erbB-2 immunostaining was significantly associated with disease progression (p<0.05). In case of CIN I, there was not noted stained specimen but in case of invasive carcinoma, 24 cases of stained specimen were noted. S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.(p>0.05) CONCLUSIONS: According to our results, c-erbB-2 is possible factor in Carcinogenesis of cervical carcinoma with progression of it. and S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.

PURPOSE: The Purpose of this research was to develop the integrative exercise program for the elderly. METHOD: The first step was to survey the elder's health status and general health problems. The second step was to design the exercise type, intensity, time and frequency. RESULT: 1. Elders who implement the integrative exercise program had weaker health status, lower physical performance and more depression than any other places. 2. The integrative exercise program developed the preparation stage composed of stretching and Yudongkong-Ki exercise, the central stage was composed of range of motion exercise, muscle strength exercise and aerobic exercise with favorite and popular Korean music. The finishing stage was composed of joint rounding and Yudongkong-Ki exercise. The exercise intensity was RPE(rating perceived exertion) 10-11, maximal pulse rate 40-60%, duration started from 20min to 50min and frequency is 2-3times/wk. CONCLUSION: The integrative exercise program developed by the researcher is tailored exercise that is more applicable to individual cases in community settings. Eventually, the program is safely applicable to the elders, and is expected to improve the elders' physical function and quality of life.

BACKGROUND: The dose-responses of neuromuscular blocking agents may be influenced by many factors including age and inhalation anesthetics. This study was designed to determine the dose-response relationships of a new, short-acting muscle relaxant, mivacurium during nitrous oxide-halothane or nitrous oxide-enflurane anesthesia in two age groups, infants and 1 to 6 years old preschool children. METHODS: Neuromuscular blockade was monitored by recording the accelerographic activity of the adductor pollicis muscle resulting from supramaximal stimulation at the ulnar nerve at 2 Hz for 2 seconds at 10-second intervals. To estimate dose-response relationships, 24 infants or children of two anesthetic subgroups for each age group received single bolus doses of 45~100 g/kg of mivacurium. The ED50 and ED95 were estimated from linear regression plots of log-dose vs probit of twitch depression. The lag time, onset time and maximal depression of twitch height for the selective medium dose were mesured. RESULTS: The ED50 and ED95 for the infants group were 38.2 and 53.3 g/kg during halothane anesthesia, and 29.8 and 48.6 g/kg during enflurane anesthesia, respectively. And, those for preschool children group were 49.4 and 90.7 g/kg during halothane anesthesia, and 32.3 and 81.4 g/kg during enflurane anesthesia, respectively. There was a parallelism of the dose-response curve between halothane and enflurane anesthesia in either age group. Also, there was statistically significant difference in the maximal twitch depression for the selective medium dose of mivacurium between halothane and enflurane anesthesia in either group. CONCLUSIONS: The potency of mivacurium during enflurane anesthesia is higher than that during halothane anesthesia in infants and preschool children, and during either inhalation anesthesia the dose of mivacurium is less required in infants than preschool children.
