본 연구는 한국인의 삶의 균형을 측정하는 도구를 개발하기 위해 Matuska(2012)의 Life Balance Inventory를 번안 및 수정하여 20세-49세 경제활동 인구를 대상으로 한국형 삶의 균형 척도를 타당화하였다. 연구 1에서는 대학생과 직장인 305명(표본 1)을 대상으로 번안한 원척도 문항에 대한 예비검사를 실시하였다. 탐색적 및 확인적 요인분석 결과 원척도가 제시한 건강, 관계, 정체성, 도전의 4요인에서 보다 세분화된 9개의 요인으로 나타났다. 연구 2는 표본 1과 유사한 성격을 지닌 대학생과 직장인 310명(표본 2)를 대상으로 본 검사를 실시하였다. 확인적 요인분석 결과는 예비검사의 결과와 동일하게 9개의 요인구조가 적절한 것으로 나타났다. 구체적으로 원척도의 건강영역은 기본적 삶유지 요인, 관계영역은 안정적 관계와 새로운 관계 요인, 정체성영역은 개인적 성장과 사회적 성장 요인, 도전영역은 역량개발, 탐험, 취미 그리고 자기표현의 요인으로 세분화되어 나타났다. 준거타당도는 주관적 안녕감, 자율성 기본심리욕구, 삶의 의미발견, 삶의 만족도, 스트레스로 검증하였다. 본 연구는 삶의 균형을 연구할 수 있는 측정 도구를 한국형으로 타당화하여 우리사회에 중요한 화두인 균형있는 삶의 국내 연구 확산을 가능하게 한 의의가 있다. This study aimed to validate the Korean Life Balance scale using Matuska’s (2010) Life Balance Inventory among 20-50 years old who actively engage in economic activities. In Study 1, we performed exploratory and confirmatory factor analyses with 305 college students and employees (Sample 1) after translating and revising the original scale items in Korea. As result, a 9 factor model was supported. The 9 factor model was corresponded with the original 4 factor model. In Study 2, we cross-validated the result of study 1 with 310 college students and employees (Sample 2). A confirmatory factor analysis confirmed the 9–factor model from study 1. The criterion-related validity was confirmed: the Korean Life Balance Scale was positively correlated with subjective well-being, autonomy basic psychological need, found of meaning in life, and life satisfaction. These findings suggest that the Korean Life Balance scale is a reliable and valid measure for assessing life balance in Korea.

Benign prostatic hyperplasia (BPH) and sexual dysfunction are prevalent in men as aging. Moreover, medical treatment for BPH may be associated with sexual dysfunction, and some men, after medical treatment with alpha-blocker or 5-alpha reductase inhibitor, experience sexual problems. Therefore, this article summarized the influence of BPH medication on male sexual function.

With increased use of abdominal imaging studies, the diagnosis of kidney cancer has shifted toward early diagnoses of renal masses. Most of those tumors are small in sized. Treatment decision making for small renal tumors are challenging clinical problem, especially in elderly and unfit patients. Significant proportion of these small renal masses (SRMs) are benign tumors or low-grade renal cell carcinomas, with relatively indolent biologic and clinical behavior. According to the evidence suggests, percutaneous needle biopsies to clarify the pathological diagnosis of a renal mass as an aid to clinical decision making should be considered more frequently, especially in SRMs.

The purpose of this study was to examine the effects of 16 weeks of combined exercise training on daily living fitness, vascular elasticity, and blood components in elderly women with type 2 diabetes mellitus (DM). Subjects in combined exercise training group (EX: n=13) participated in combined exercise training 30-40 min/session, 4 sessions/wk for 16 weeks, whereas subjects in control group (CON: n=13) were asked to maintain their normal life pattern during the same intervention period. Main results of the present study were as follows: 1) Percent body fat and fat mass decreased significantly in the EX, and there was a significant interaction between group and test in fat-free mass. 2) Arm curl, chair stand, one leg with eyes opened, functional reach, tandem test, 10m walking, and VO2max improved significantly in the EX, and there were significant interactions between group and test in chair sit-and-reach and up & go. 3) No significant changes were shown in all variables regarding vascular elasticity, and diastolic blood pressure increased significantly in the EX. 4) TG decreased significantly in the EX, and there was a significant interaction between group and test in LDL-C. 5) There were significant interactions between group and test in fasting plasma insulin and HOMA-IR. It was concluded that 16 weeks of combined exercise training would be beneficial for improvement of body composition and physical fitness as well as for preventing senile deterioration of blood lipid profiles and insulin resistance in elderly women with type 2 DM.

The objective of this study is to simulate valve flow coefficient and flow characteristics such as velocity and pressure distribution for butterfly valve. The size of the valve used in this study is 125A. The range of the valve opening angle was α=15°∼70°, and it was changed by 5°. At the range of α=15°∼30°, the valve flow coefficient K_v gradually increased, and after α=30°, it increased rapidly. In the range of α=20°∼70°, the pressure change in the -2.9cm∼+2.9cm region in the pipe greatly depended on the opening angle and the position within the pipe. However, after +2.9cm, the pressure at the rear end of the valve was shown to depend only on the opening angle. At α=20°, Vortex shedding occurred for the first time at time t=0.25sec and continuously occurred in rear end of the valve over time. After α=45°, in the flow pattern at the rear end of the valve, the upward flow at the lower end of the valve and the flow at the upper end met each other to form a mixed flow. This flow phenomenon was shown to form a more intense mixed flow in the rear end region as the opening angle increased. Vortex flow occurred for the first time at α=15°, and the opening angle increased, the occurrence and disappearance of this flow phenomenon occurred periodically according to the certain flow region. The pattern of the pressure distribution in the region at the rear end of the valve showed a tendency to agree well with the results of the vorticity distribution.

A Case Giving Proof of Pathogenesis of Abdominoscrotal Hydrocele: A Case Report

양희조,손명원,김두상 순천향대학교 순천향의학연구소 2021 Journal of Soonchunhyang Medical Science Vol.27 No.2

An abdominoscrotal hydrocele (ASH) is an uncommon condition characterized by cystic mass that occupies the scrotum and abdomen. The characteristic aspect is the presence of two hydrocele sacs in the abdominal cavity and the scrotum, and compression of one side causes enlargement of the other side, thereby connecting the two sacs. There are several hypotheses regarding the occurrence of ASH. However, the evidence of the hypotheses is lacking. The patient was a 52-year-old male. During observation of the right inguinoscrotal hydrocele, the patient complained of a palpable mass lesion on the right lower quadrant of the abdomen. Physical examination revealed ASH that occurred with the growth of the inguinoscrotal hydrocele. This was further confirmed by sequential imaging test thereby proposing the verification of cephalad extension of hydrocele. The surgical excision was recommended and inguinal exploration was performed under general anesthesia. No evidence of relapse was observed during the 2-year follow-up period after surgery. The present case proves the cephalad extension of hydrocele among other hypotheses on the etiology of ASH.

Objective To identify predictive factors for favorable outcomes after surgical treatments that were performed by beginner urologists in patients with benign prostate hyperplasia (BPH), we retrospectively evaluated outcomes after holmium laser enucleation of the prostate (HoLEP) and transurethral resection of prostate (TURP) that were performed by two young urologists. Methods Of 80 patients who were treated with HoLEP or TURP, 31 (HoLEP) and 36 (TURP) patients who were followed up for 3 months were enrolled in this study. Preoperative and perioperative variables were evaluated to identify predictive factors for favorable outcome after surgical treatment for BPH. Results At 3 months postoperative after HoLEP or TURP, the median decrease in International Prostate Symptom Score (IPSS) was 13.0. Patients whose IPSS decreased by over 13 points were categorized into a favorable response group after HoLEP or TURP. Univariate and multivariate logistic regression analyses were performed to identify predictors of favorable outcomes at 3 months after HoLEP or TURP, and the preoperative IPSS was identified as an independent predictor for favorable outcomes. Conclusion When young urologists plan to perform surgical treatment for BPH, they should consider that the severity of symptoms is the most important factor for favorable outcomes. The type of surgical modality for managing BPH is less important.
