본 연구는 노인의 신체적 활동 및 사회적 활동을 장려하며, 나아가 노인의 건강과 정신적 건강을 제고할 수 있는 물리적 환경을 분석하는데 그 목적이 있다. 본 연구의 방법은 설문조사 및 구조방정식모형을 활용한 통계분석이다. 설문조사는 서울의 종로구, 동작구, 구로구, 광진구, 강서구에 거주하는 60세 이상 노인들을 대상으로 하여 총 500명을 대상으로 일대일 면접조사를 실시하였으며, 설문응답자의 주소를 중심으로 반경 500m의 물리적 환경과 이들의 사회적 활동, 신체건강 및 정신건강의 관계를 구조방정식 모델을 이용하여 분석하였다. 분석 결과, 근린의 물리적 환경이 노인의 신체적 활동을 장려하는 역할을 할 수 있음을 확인하였으며, 나아가 이러한 신체적 활동이 노인의 건강 상태를 제고할 수 있는 것으로 나타났다. 우선, 근린의 보행환경이 양호한 곳에서 노인들의 경로당 및 복지관 이용과 같은 표현활동이 장려되었으며, 동창회나 향우회와 같은 지역 기반의 연고집단활동이 장려되었다. 반면, 대중

Sex steroids influence the maintenance and growth of muscles. Decline in androgens, estrogens and progesterone by aging leads to the loss of muscular function and mass, sarcopenia. These steroid hormones can interact with different signaling pathways through their receptors. To date, sex steroid hormone receptors and their exact roles are not completely defined in skeletal and smooth muscles. Although numerous studies focused on the effects of sex steroid hormones on different types of cells, st

Our results suggest that resuming TNFi therapy in patients following adequate TB treatment is safe, even before completion of TB treatment.

Magnetic skyrmions are stable spin textures with quasi-particle behavior and attract significant interest in fundamental and applied physics. The metastability of magnetic skyrmions at zero magnetic field is particularly important to enable, for instance, a skyrmion racetrack memory. Here, the results of the nucleation of stable skyrmions and formation of ordered skyrmion lattices by magnetic force microscopy in (Pt/CoFeSiB/W)_<i>n</i> multilayers, exploiting the additive effect of the

Intrauterine insemination (IUI) is a widely used fertility treatment for couples with male and/or non-male factor infertility and is a relatively simple and inexpensive procedure. When used for unexplained infertility, IUI combined with ovarian stimulation increases the pregnancy rates, but evidence does not support this to be true when applied for male factor infertility. Recently, the revised World Health Organization laboratory manual for semen criteria provided a new insight for practical gu

The expression profile of microRNA (miRNA) in uterine leiomyoma (UL) cells is different from that in normal uterine myometrial (UM) cells. The effect of UL cells on uterine receptivity might vary according to their ability to distort the uterine endometrial cavity. However, the variation in miRNA expression profiles between endometrial cavity-distorting leiomyoma (ECDL) and endometrial cavity non-distorting leiomyoma (ECNDL) cells remains unknown. This study aimed to elucidate whether the expres

In vitro culture of ovarian follicles is a promising bioengineering technique for retrieving fertilizable oocytes from preserved ovarian tissues of cancer survivors. However, current in vitro follicle culture techniques are labour-intensive and of low efficiency, as only single follicle culture (SFC) has been possible to date. The present study investigated the feasibility of multifollicular cluster culture (MFCC) system using angiotensin II receptor (ATII-Rc) analogues. Ovarian pre-antral folli

Abstract The switching of magnetization via spin‐orbit torque has attracted much attention because of its fast switching and low power consumption. Numerous studies have focused on increasing the conversion efficiency from charge to spin current and out‐of‐plane magnetization cases. Recently, there have been reports on the fast and deterministic switching of in‐plane magnetization devices. It is reported that an in‐plane spin‐orbit torque (SOT) device can archive the oscillation, precession, and

The filamentous fungus Aspergillus nidulans primarily reproduces by forming asexual spores called conidia and produces the mycotoxin sterigmatocystin (ST), the penultimate precursor of aflatoxins. It has been known that asexual development and ST production are tightly co-regulated by various regulatory inputs. Here, we report that the novel regulator AslA with a C₂H₂ domain oppositely regulates development and ST biosynthesis. Nullifying aslA resulted in defective conidiat
