Purpose: This study was to identify the effects of aroma inhalation therapy on heart rate variability and anxiety in the context of urodynamics study. Method: The data were collected from 64 patients who were receiving urodynamics at the C University Medical Center in Seoul, 23 in the experimental group, 22 in the placebo group and 19 in the control group. In the experiment, the subjects of the experimental group inhaled a mixture of lavender and bergamot for 5 min, the subjects of the placebo group inhaled geranyl acetate oil for 5 min and the subjects of the control group relaxed for 5 min. The instruments used in this study included the state anxiety inventory and heart rate variability. Result: The score of state anxiety was no significant differences between the three groups after aroma-inhalation. Also, the sympathetic nerve activity and parasympathetic nerve activity was no significant differences between the three groups after aroma-inhalation. Autonomic nerve balance was maintained significantly in the experimental group as compared to the control groups after aroma-inhalation. Conclusion: The aroma inhalation therapy was very effective in balancing the autonomic nervous system in the patients undergoing urodynamic study.

The purpose of urodynamic investigation is to determine information on the function of the urinary system. One of the most frequently used measurement procedures in urodynamics is filling and voiding cystometry using invasive method. But in this method transurethral catheter is use and it makes patients uncomfortable. The aim of this study was to implement the system that could evaluate the function of urinary tract with noninvasive and comfortable method. Therefor in this study, a sensor and measuring system were implemented to measure uroflow, urophonography and noninvasive bladder pressure signal during urination for diagnosing the LUTS(lower urinary tract symptoms) using noninvasive method. The implemented system compose of the sensor parts, signal conditioning parts, system control parts using FPGA and PC monitoring program. For the evaluation of the implemented system, the simulation of system's control part was performed and the model system for the lower urinary system was designed. From the evaluation of the model system, the mean error rate of the uroflow measurement part was 1.08% and coefficient of variation was 1,48. And the mean error rate of the noninvasive bladder pressure measurement part was 2.41% and coefficient of variation was 2.81. urophongraphy signal analysis was accomplished in a time domain and frequency domain. Average RMS power was used in a time domain analysis, and MF was used in a frequency domain analysis. From the evaluation of the model system average RMS power and MF was dependent on the occlusion degree significantly and median frequency range of $60{\sim}160Hz$ was correlated with the occlusion.

Urodynamic study system is widely used for neurogenic bladder patients in various clinical setting. Generally they include 2 pressure sensors from bladder and rectum, and 1 EMG sensor. The rectal pressure catheter is often the source of data error because of gas passage and the fall out of the catheter from anus, and source of discomfort in ambulatory urodynamic system. This study is to design and calibrate the ambulatory digital urodynamic study system that can discard the rectal pressure catheter, which can make patients more comfortable and doctors can get more physiologic data. As a first step, we compared our new system with Dantec $Duet^{(r)}$ urodynamic system (Dantec, Denmark) and wanted to see the possibility of our new system.

이 연구의 목적은 전통적으로 남성 주도적인 전문직 진출을 희망하는 여대생(이 연구에서는 법률가 및 의사직, 이하 비 전통적인 여성이라 부름)과 전통적으로 여성 주도적인 전문직 진출을 준비중인 여대생 (이 연구에서는 교사 및 간호사직, 이하 전통적으로 여성 이라 부름)을 구분 할수 있는 개인의 성격 및 가족환경의 특성을 검토하는 것이었다. 남성 주도적인 전문직에 진출을 준비하거나 그 분야에 종사하는 여성들의 특성에 대한 연구가 많이 발표되었으나 그 특징들의 중요성이 상대적으로 얼마나 비중이 있는지는 연구되어 있지 않다. 발단론적 환경이론(Developmental-Contextualism)과 직업 발달에 대한 역동적 상호관계 모델(Dynamic Interaction Model)이 본 연구의 이론적 체계를 이루고 있다. 이 연구에 포함성의 위치, 심리적 남성특성, 출신가정의 사회경제수준, 그리고 부모의 뒷받침과 이해였다. ANOVA 결과에 의하면 비전통적인 여성들이 자아존중감, 학교성적 성취도, 내적 통제성, 심리적 남성특성, 그리고 출신가정의 사회경제수준 면에서 전통적인 여성에 비해 훨씬 높은 수준을 나타내었다. 단계적 분별 분석 (Stepwise Discriminant Analysis) 결과에 따르면, 심리적 남성 특성, 내적 통제성, 학교성적 성취도, 그리고 출신가정의 사회경제수준이 위 두집단의 여성들을 분별하는 가장 뛰어난 특성들이었으며 전체 표본의 76.99%가 이 요인들에 의해 정확하게 분류되었다. 이 연구의 결과를 토대로 볼 때, 역동적 상호관계모델은 여성의 직업발달을 연구하는데 있어서 이론정립과 검사에 유효한 도구로 보이며, 이 연구에 포함한 변수들은 비 전통적인 여성들의 특성을 정확하게 묘사하는데 상당한 공헌을 하고 있었다. 마지막으로, 비전통적인 여성들의 직업발달을 연구하는데 있어서 "능력특성군(Competency-related traits)"의 변수들을 좀 더 정확하게 분류할 필요가 있으며, 이 변수들과 여성의 직업발달의 관계를 자세히 연구할 필요가 있다고 본다.요가 있다고 본다.

Leigh syndrome is a rare progressive neurodegenerative mitochondrial disorder with clinical and genetic heterogeneity. Recently, balletic IARS2 variants have been identified in a number of patients presenting broad clinical phenotypes from Leigh and West syndrome to a rare syndrome CAGSSS characterized by cataracts, growth hormone deficiency, sensory neuropathy, sensorineural hearing loss, and skeletal dysplasia syndrome (OMIM#616007). We describe a child with Korean Leigh syndrome with urologic manifestations resulting from a compound heterozygote mutation in IARS2. A 5-year-old girl visited the emergency room with a complaint of abdominal pain accompanied by abdominal distension. Abdominal-pelvic CT showed a markedly distended urinary bladder without definite obstructive lesions. She was diagnosed with neurogenic bladder dysfunction based on a urodynamic study. She had global delayed development due to neurologic regression after 6 months of age and a history of bilateral cataract surgery at the age of 2 years. Her brain magnetic resonance imaging showed symmetrically increased signal intensities in the bilateral putamen and caudate nuclei with diffuse cerebral atrophy. No gene variants were identified through whole-mitochondrial genome analysis. Whole exome sequencing was performed for diagnosis, and compound heterozygous pathogenic variants were identified in IARS2: c.2446C>T (p. Arg816Ter) and c.2450G>A (p. Arg817His). To the best of our knowledge, this is the first case report of bladder dysfunction manifestation in a patient with IARS2-related Leigh syndrome. Thus, it broadens the clinical and genetic spectrum of IARS2-associated diseases.
