Purpose: This study was conducted to develop a predictive model for happiness of students in general high schools.The study was based on the theory of happiness integration and the literature review. Methods: Data were collected using a convenience sample of 231 first and second grade students in five general high schools in D city and K Province. The exogenous variables were optimism as personality factors, parenting attitude, academic stress and friend’s support as happiness. The endogenous variables were self-esteem and resilience as mediating variables, and happiness of students in general high schools. Data collection was done from March 14 to March 28, 2019. The AMOS 22.0 and SPSS programs were used to verify the validity of confirmatory factor analysis and hypothesis models. Results: The factors that have the greatest influence on happiness of high school students are self-esteem and resilience. The explanatory power of happiness by these variables was 98.1%. The individual mediating effect and double mediation effect of these variables were found to be significant. Conclusion As student's optimistic personality, parent's positive parenting attitude, and friend’s support improve student's self-esteem and resilience, ultimately positively affecting high school students' happiness, so it is necessary to consider these factors and try to develop a happiness improvement program.

PURPOSE: The purpose of this study was to investigate hemato-oncology patients' discomfort and bleeding in relation to the bedrest time after bone marrow examination. METHODS: A descriptive correlational study was conducted. The data were collected using self-report questionnaire from total of 131 patients who underwent bone marrow examination from January 2017 to September 2017. Data were analyzed with descriptive statistics, Wilcoxon Signed-rank test, McNemar's test and logistic regression. RESULTS: The level of discomfort after 4 hours of bedrest was significantly higher when compared to 2 hours of bedrest(p<.001). The occurrence of bleeding after 2 hours of bedrest was significantly higher than 4 hours of bedrest(p<.001), however the degree of bleeding was slight. No bleeding occurred in 84% of the patients after 2 hours of bedrest. CONCLUSION: The results of this study demonstrated that shortening the bed rest time after bone marrow examination was helpful in improving the patient's well-being. Bedrest time could be shortened according to the site of bone marrow examination and patient's condition.

BACKGROUND AND PURPOSE: Visual assessment of medial temporal-lobe atrophy (MTA) has been quick, reliable, and easy to apply in routine clinical practice. However, one of the limitations in visual assessments of MTA is the lack of widely accepted age-adjusted norms and cutoff scores for MTA for a diagnosis of Alzheimer's disease (AD). This study aimed to determine the optimal cutoff score on a T1-weighted axial MTA Visual Rating Scale (VRS) for differentiating patients with AD from cognitively normal elderly people. METHODS: The 3,430 recruited subjects comprising 1,427 with no cognitive impairment (NC) and 2003 AD patients were divided into age ranges of 50–59, 60–69, 70–79, and 80–89 years. Of these, 446 participants (218 in the NC group and 228 in the AD group) were chosen by random sampling for inclusion in this study. Each decade age group included 57 individuals, with the exception of 47 subjects being included in the 80- to 89-year NC group. The scores on the T1-weighted axial MTA VRS were graded by two neurologists. The cutoff values were evaluated from the area under the receiver operating characteristic curve. RESULTS: The optimal axial MTA VRS cutoff score from discriminating AD from NC increased with age: it was ≥as ≥1, ≥2, and ≥3 in subjects aged 50–59, 60–69, 70–79, and 80–89 years, respectively (all p < 0.001). CONCLUSIONS: These results show that the optimal cutoff score on the axial MTA VRS for diagnosing of AD differed according to the decade age group. This information could be of practical usefulness in the clinical setting.

Immediate-type hypersensitivity responses to systemic corticosteroids are rare despite their widespread use. It is still controversial whether the responses rarely occur or are underdiagnosed in clinical settings. Many cases probably remain underdiagnosed because the symptoms often mimic symptoms of underlying diseases. This case report describes a 73-year-old man who had immediate hypersensitivity reactions after intravenous administration of hydrocortisone, which was primarily intended to prevent hypersensitivity reactions to contrast media. Whole body rash with pruritus developed shortly after the steroid injection. Since the patient already experienced rash and itching sense after contrast media and antihistamine injection, we conducted skin testing to figure out which drug triggered the hypersensitivity reactions. Intradermal skin tests revealed a positive response to hydrocortisone sodium succinate, which suggested his hypersensitivity reactions were developed by hydrocortisone. Being a common therapy for allergic reaction, corticosteroids themselves are rarely suspected of causing hypersensitivity reactions. Considering there is no typical symptom or standard diagnostic test, awareness of corticosteroid hypersensitivity reactions is of importance to make the diagnosis.

OBJECTIVES: This research was carried out to identify the synergistic effect of dexmedetomidine and ketorolac on neuropathic pain alleviation. METHODS: The anti-allodynic effect of intrathecal dexmedetomidine and ketorolac was investigated in rats after L5 spinal nerve ligation (SNL). Mechanical allodynia was assessed using Von Frey filaments. Every day for 3 consecutive days, beginning on the 10th day after SNL, behavioral tests were carried out at 1, 2, and 4 hr after drug injection. RESULTS: Significant increases in ipsilateral paw withdrawal thresholds (PWTs) were observed 1, 2, and 4 hr after drug injection in the groups of rats which received intrathecal injection of either dexmedetomidine (group D) or ketorolac (group K), compared to group S (P < 0.05). And group DK, which received simultaneous intrathecal injection of both dexmedetomidine and ketorolac, showed statistically significantly higher ipsilateral PWTs than groups D and K, which received only one of them (P < 0.05). CONCLUSIONS: The results of this research demonstrated the anti-allodynic effect of dexmedetomidine and ketorolac on neuropathic pain induced by SNL in rats. They also suggest that synergistic analgesia can be induced by the simultaneous injection of dexmedetomidine and ketorolac, and that combination therapy is an effective approach to treating chronic neuropathic pain syndrome.

Here, we report the poisoning case of 10 cows. Several distinct clinical signs such as convulsion, excessive salivation, circling, lateral recumbency, and death were observed. Necropsy and histopathological examination did not reveal any significant abnormal findings. Moreover, no bacteria or viruses were detected in tissue, blood, and feeding food. However, endosulfan was detected from the stomach contents and microbials. Our results strongly suggest that death of cows may be closely associated with endosulfan poisoning.

Soft fibromas are benign fibrous tissue tumors of the dermis. In general, they appear as small, soft, pedunculated or sessile tumors and they are mostly located on the axillae, lateral neck and inguinal region. Although large sized soft fibromas may occur in the groin or upper thighs, and especially in patients with diabetes, they rarely exceed 2 cm in size. We report herein a case of multiple giant soft fibromas, including an unusually huge, giant lesion in the labium majus of a healthy, middle-aged woman, and such fibromas on the labium majus are very rare.

BACKGROUND: To standardize renal biopsy reporting and diagnosis, The Renal Pathology Study Group of the Korean Society of Pathologists (RPSKSP) has developed a renal pathology reporting format for the native and allograft kidney. METHODS: A consensus checklist of a provisional renal biopsy format was sent to all members of the RPSKSP. Feed back opinions regarding the practical application of the checklist to the diagnostic work were received. RESULTS: Kidney biopsies require three essential examinations: by light microscopy, immunofluorescence (IF), and electron microscopy (EM). A final report of a renal biopsy should include information on specimen adequacy and a description of the morphologic change using a systematic semiquantitative method for each of the compartments, with optional separate IF and EM reports. CONCLUSIONS: A standard renal biopsy report format is important in establishing clinicopathologic correlations, making reliable prognostic considerations, comparing the findings in sequential biopsies and evaluating the effects of therapy.
