The purpose of this study was to identify factors affecting the mental health of female middle school students living in rural areas. The study period was from March 14 to 25, 2022, and was conducted with 239 female middle school students attending three middle schools located in G district. The collected data were analyzed using descriptive statistics, t-test, Pearson's correlation, and multiple regression. As a result of the study, significant influencing factors on the subject's mental health were living with both parents (β=.12, t=2.50, p =.013), past subjective mental health status (β=.15, t=2.83, p=.005), subjective physical health status (β=-.21, t=-3.94, p<.001), loneliness (β=.22, t=4.23, p<.001), and severity of insomnia (β=.36, t=6.55, p<.001), and these variables showed 46% explanatory power for mental health. Through this study, further research is needed to specify the causal relationship between living with both parents, past mental health status, physical health status, loneliness, and severity of insomnia and intervention strategies for the mental health of female middle school students considering these variables.

The purpose of this study is to obtain information necessary for the development of patient clothes that can reduce physical fatigue of caregivers by quantitatively measuring the muscle load and fatigue. The patient clothes used in this study can be broken down into three types: A type (back center zipper open suit), B type (top-to bottom separated patient clothes), and C type (front zipper open suit). The EMG measurement sites are as follows: hand muscle (brachioradialis), upper arm (biceps, triceps), shoulder (anterior deltoid, medial deltoid, posterior deltoid, upper trapezius), and waist (erector spinae); additionally, the EMG signals were measured. Through this experiment, muscle load, muscle energy consumption, and muscle fatigue generation tendency were analyzed. The results of the study revealed that the C type patient clothes required the most strength in the muscles of the shoulders, upper arms, hands, and back when being put on and taken off compared to other patient clothes. The A type clothes required a relatively large force in opening the zipper. In terms of muscle energy consumption, B type generally called for more strength when it came to the zip-up and putarmsup motions. With regard to the cover the body and put legs/hips up motions, C type used the highest amount of muscle energy, whereas A type used relatively little energy. In terms of the occurrence of muscle fatigue during the putting on and taking off of the patient's clothing, there was a difference in the area and degree of muscle fatigue in the A, B, and C types, and there was also a tendency for muscle fatigue to occur when performing repetitive movements.

기존의 전동휠체어를 사용하는 약자 또는 중증 장애인 등 지체(肢體)가 불편한 사람들이 휠체어 사용 시 생기는 문제점을 해소할 목적으로 시작되었다. 이는 전동휠체어가 보행 기구임에도 자동차에 준하는 교통사고에 대해 무방비하게 노출되고, 중증 장애인에 대한 이동권 보장이 아직 미흡하여 생기는 문제이다. 따라서 본 연구에서는 이러한 문제로 인한 불편함을 해소하고자 아이트래킹을 이용한 스마트 전동휠체어 기술을 적용하고자 한다. 루게릭병 등으로 인해 지체(肢體)의 움직임에 제한이 있는 사람들에게 보호자가 밀어주는 휠체어에 의존하는 것이 아닌 Eye-Tracker를 이용한 시선 추적(Eye-Tracking) 기술로 휠체어 동작이 가능하다. Web-Cam과 라즈베리 파이를 통해 얻은 전·후·좌·우의 영상정보를 디스플레이 화면에 송출한다. 그 후 Eye-Tracking 기술을 이용해 디스플레이 화면에 표시된 전·후·좌·우 이동에 관한 UI(User Interface)룰 사용자가 송출된 영상을 보면서 눈의 움직임만으로 선택해 휠체어의 방향을 제어한다. 또한 전동휠체어의 조작 실수로 다른 행인 또는 장애물과 충돌하는 문제점을 초음파 센서를 이용하여 일정 거리 내에 사물이나 사람이 있을 경우 디스플레이 화면에 경고표시 및 경고음, 각 초음파 센서 위치에 맞는 LED작동으로 사용자들에게 추돌 위험경고와 함께 장애물의 위치파악이 가능하도록 한다. 따라서 스마트 전동휠체어를 통하여 수동적인 움직임이 아닌 능동적이고, 초음파 센서로 인해 안전한 이동이 가능하게 한다.

Accidents at construction sites have a very high rate of fatalities due to the nature of being prone to severe injury patients. In order to reduce the mortality rate of severely injury patients, quick response is required, and some systems that detect accidents using AI technology and cameras have been devised to respond quickly to accidents. However, since existing accident detection systems use only a single camera, there are blind spots, Thus, they cannot detect all accidents at a construction site. Therefore, in this paper, we present the system that minimizes the detection blind spot by using multiple cameras. Our implemented system extracts feature points from the images of multiple cameras with the YOLO-pose library, and inputs the extracted feature points to a Long Short Term Memory-based recurrent neural network in order to detect accidents. In our experimental result, we confirme that the proposed system shows high accuracy while minimizing detection blind spots by using multiple cameras.

This study aimed to investigate the relationship between overt and covert characteristics of stuttering. This study included 10 adult participants who stutter. To analyze the overt characteristics, stuttering frequency, duration of stuttering moments, concomitant behaviors, and total score were scored based on the Stuttering Severity Instrument-Fourth Edition (SSI-4). Additionally, the modified Erickson scale of communication attitudes (S-24) and the Overall Assessment of the Speaker's Experience of Stuttering for Adults (OASES-A; general information, reactions to stuttering, communication in daily situations, quality of life, and total score) were used to determine the covert characteristics. Correlation analyses showed no significant association between the overt and covert variables. However, there were significant correlations between the scores on the S-24 and the OASES-A. These findings support the perspective that the overt characteristics of stuttering do not predict the covert characteristics, and vice versa. Therefore, when evaluating and intervening with adults who stutter, it is important to consider these characteristics separately.

Ischemic stroke is one of the manifestations of reversible cerebral vasoconstriction syndrome (RCVS). Many precipitants and associated disorders of RCVS have been suggested. However, few case reports have indicated an association between anemia and RCVS. Here, we report a case of a 66-year-old female with severe iron deficiency anemia (IDA), who presented with ischemic stroke and cerebral vasoconstriction, which gradually improved with conservative treatment. High-resolution vessel wall magnetic resonance imaging findings and reversibility suggested the possibility of RCVS. In patients with RCVS and ischemic stroke, IDA should be considered. Prompt management should be delivered to prevent disease progression and recurrence.

병원은 다양한 의료서비스를 제공하기 위해 의료기관 별 운영 전략에 따라 각기 다른 방식으로 운영된다. 특히 종합의료시설은 중증도가 높은 환자를 대상으로 수술이나 입원 등의 의료서비스를 효율적으로 제공하고자 그에 따른 운영 전략이 상이하다. 이러한 병원의 운영방식에 의해 결정되는 건축 역시, 건립 시기, 유형, 중증도에 따른 병원의 규모 등에 따라 시설 수준의 차이가 나타나며 이는 최근 정부에서 요구되는 제도 및 정책의 수용 여부를 결정짓는 중요한 요인이 되기도 한다. 최근 의료법은 기존 의료시설뿐만 아니라 신규 의료시설에 대한 설치 및 운영기준이 강화 추세에 있고, 서울시 또한 공공의료 확충을 위해 감염관리시설이나 필수의료시설 설치를 위한 용적률 인센티브 정책을 추진 중이다. 병원 운영 환경이 상이함에 따라 종합의료시설 설치 및 운영에 대한 인센티브제도의 적용 기준을 일괄적으로 적용하기에는 어렵다. 그러나 공익을 위해서 종합의료시설 인센티브제도를 지속 가능하게 운영하기 위한 객관적이고 합리적인 기준은 반드시 필요하다. 공공의료 기능 확충을 위한 서울시 종합의료시설 지구단위계획 수립·운영 기준은 공공과 민간이 모두 만족하는 의료환경 구축을 위해 매우 깊은 고민이 필요했다. 본 논설은 서울시 공공필요의료시설 확충 제도의 주요 내용과 공공필요의료시설 설치 및 운영 기준에 관해 소개하고자 한다. 특히 기준의 주요 내용을 정립하게 된 배경과 이유 등을 설명하여 본 제도의 의의를 정확히 전달하고 향후 보완해야 할 부분들을 검토하고자 한다.

Background : Alcoholic ketoacidosis(AKA) is a metabolic disturbance that is caused by prolonged and excessive alcohol consumption. Though the prognosis is reportedly good, its outcome is unclear in some cases that are combined with multi-organ failure. There are few reports of an analysis of cases admitted to an intensive care unit(ICU) Method: Cases of AKA admitted to the ICU over the last 5 years were retrospectively analyzed. Severe AKA was characterized by multi-organ failure that required treatment in an ICU Results : All patients were males with a history of excessive alcohol consumption. Five of them (50%) mainly complained of gastrointestinal symptoms (nausea, vomiting, diarrhea), showing metabolic acidosis with an increased asmolar and anion gap. Rhabdomyolysis with acute renal failure was the most common combined organ failure. Mechanical ventilation was performed in 80%. Six patients died and 4 patients survived. In the surviving patients, the arterial blood gas analysis(ABGA) was normalized within 12 hours after admission. Conclusion : In severe AKA patients, rhabdomyolysis with acute renal failure was the most common complication. The mortality rate was high and death from shock occurred within 3 days.

Background : To characterize the clinical features and determine the prognostic factors of severe community-acquired pneumonia. This study is the first of its kind in Korea. Methods : Recruited were 40 patients diagnosed as severe community-acquired pneumonia in Hallym University Hospital from January 1, 1989 through July 31, 1996. Patients were analysed retrospectively for age, sex, underlying disease, respiration rate, hypoxemia, requirement of mechanical ventilation, involvement on chest radiograph, shock, and the serum concentration of BUN and albumin. All parameters were compared between survived and dead group. Results : Male to female ratio was 2.07 : 1. The mean age was $63.1{\pm}17.5$years(range 25~90years) with 65% of patients aged equal to or more than 60. The major underlying diseases were old pulmonary tuberculosis(12.5%), chronic obstructive pulmonary disease(7.5%), bronchial asthma(5%), bronchiectasis(2.5%), and diabetes mellitus(22.5%). Microbiologic diagnosis was made in 26 out of 40 patients(65%). The most common causative organism was S. pneumoniae(17.5%, 7/40) followed by S. aureus(15.0%, 6/40), K. Pneumoniae(12.5%, 5/40), M. tuberculosis(7.5%, 3/40), H. influenzae(2.5%, 1/40), coagulase negative staphylococcus(2.5%, 1/40), P. aeruginosa(2.5%. 1/40), E. cloaceae(2.5%, 1/40), and E. coli(2.5%, 1/40). M. pneumoniae was detected in no patient. The most frequent drugs administered in single or combination therapy were aminoglycosides(75%, 30/40), second- and third-generation cephalosporin(40%, 16/40 and 27.5%, 11/40), macrolides(27.5%, 11/40), and amoxicillin/clavulanic acid(22.5%, 9/40). Of the 40 patients, 14 died of severe community-acquired pneumonia(37.5%). Among them, seven patients (50%) expired within 72h of hospital arrival. According to multivariate analysis, mortality was significantly associated with requirement of mechanical ventilation, bilateral pulmonary involvement, and serum albumins$\leq$3.0g/dl. Conclusion : An understanding of the clinical characteristics and prognostic factors in severe community-acquired pneumonia identified in this study will optimize therapeutic approach in this disease and help decreasing its notorious mortality rate.
