Objectives: A hospital is a complex building that serves many different purposes. It has a major impact on patient's well-being as well as on the work efficiency of the hospital staff. Thermal comfort is one of the major factors in indoor comfort. The purpose of this study was to determine thermal comfort in various locations in a hospital. Methods: Various indoor environmental conditions in a general hospital were measured in February 2014. The predicted mean vote (PMV) and carbon dioxide ($CO_2$) concentration were measured simultaneously in the lobby, office, restaurant, and ward. Results: The ward was the most thermally comfortable location (PMV=0.44) and the lobby was the most uncomfortable (PMV = -1.39). However, the $CO_2$ concentration was the highest in the ward (896 ppm) and the lowest in the lobby (572 ppm). The average PMV value was the most comfortable in the ward and the lowest in the lobby. In contrast, for concentration of carbon dioxide, the highest average was in the ward and the lowest in the lobby. Due to air conditioner operation, during operating hours the PMV showed values close to 0 compared to the non-operating time. Correlation between PMV and $CO_2$ differed by location. Conclusion: The PMV and concentration of carbon dioxide of the hospital lobby, office, restaurant and ward varied. The relationship between PMV and carbon dioxide differed by location. Consideration of how to apply PMV and carbon dioxide is needed when evaluating indoor comfort.

Purpose: This study was conducted to present the levels of self-compassion, active coping, passive coping, and compassion fatigue and satisfaction, and explore the influence of self-compassion, active coping, and passive coping on compassion fatigue and satisfaction among nurses working at veterans’ hospitals. Methods: A correlational study design was used. The respondents were 148 staff nurses who had worked for more than a year in the general ward of four veterans’ hospitals in Korea. Data were collected from March to April 2019 via a self-administered questionnaire. Results: The respondents’ mean age was 31.49±6.85 and clinical experience 8.82±6.67 years. While compassion fatigue was significantly higher in nurses having veterans in the family (t=-2.59, p=.010), compassion satisfaction was significantly higher in those aged 41 and above (F=4.18, p=.018), married (t=-2.38, p=.018), having a higher monthly income (t=-2.59, p=.010), and having a hobby (t=-3.34, p=.001). There was a significant relationship between compassion fatigue and satisfaction (r=.21, p=.010). Regression analysis showed that the compassion fatigue score was higher when nurses had veterans in the family(β=.21, t=2.68, p=.008), with a 4.8% explained variance. Nurses engaging in more active coping (β=.34, t=3.70, p<.001) and less passive coping (β=-.24, t=-2.89, p=.004), and having a hobby (β=.19, t=2.50, p=.013) reported higher levels of compassion satisfaction. Conclusion: More active coping and less passive coping impacted compassion satisfaction significantly. Thus, there is a need to provide support to nurses so that they can utilize effective ways of coping with stress to improve their compassion satisfaction.

Background: The development of technology can be beneficial for the life and health of human society. Crowdsourcing refers to drawing upon a large pool of individuals in order to seek services, ideas, or other contributions. With the development of information communication technology, crowdsourcing is able to provide powerful results in environmental health research. Methods: We searched 'crowdsourcing' and 'citizen science' for keywords related to the environmental health field and only selected journal articles and conference proceedings material, such as research reports and WHO reports. Results: This paper reviewed environmental health research using crowdsourcing. Examples of such research based on crowdsourcing included practices in environmental disasters, noise monitoring, global positioning system (GPS) technology, smart phones, attached portable devices and information delivery by web. Crowdsourcing methods can provide notably distinct approaches for future environmental health research. However, it is also important to protect personal information whenever crowdsourcing is applied to data generation and information dissemination. Conclusion: We expect that this review may provide useful information for the development of new environmental health research methods using crowdsourcing and citizen science.

Objectives The objective of this study is to investigate the application of Sifeng point (EX-UE 10) in children and to make suggestions for domestic research and clinical application by reviewing relevant randomized controlled trials. Methods Eight electronic databases including English, Chinese, Korean databases were comprehensively searched for randomized controlled trials evaluating the effects of Sifeng point in children up to May 2, 2018. We extracted the year of publication, country, target diseases or symptoms, location of Sifeng, acupuncture method; such as acupuncture tool and depth of insertion, and frequency, number, and duration of the treatment. Results Fifty studies were included for analysis. All the included studies were conducted in China, and studies were published from 1962 to 2017. The most frequent target symptom was anorexia (46%). In addition, Sifeng point was used for digestive diseases or symptoms such as diarrhea, constipation, and mesenteric lymphadenitis, as well as respiratory diseases or symptoms such as cough, cold, acute bronchiolitis, recurrent respiratory tract infections, bronchopneumonia, and asthmatic bronchitis. Also, allergic diseases such as chronic urticaria, and other variety of symptoms such as malnutrition, fever, and iron-deficiency anemia were treated with the Sifeng point. The location of Sifeng points was inconsistent, and the most common location of the Sifeng point was the midpoint of transverse creases of the proximal interphalangeal joints of the index, middle, ring and little fingers (84.2%). The most commonly used acupuncture tool was three-edged needle (40.9%). All included studies have the method of squeezing out blood or mucus from the Sifeng points. The treatment was mostly conducted once per week (35.4%), mostly repeated for 4 times (32.6%). The most common treatment duration was 4 weeks (18.6%). Conclusions We could identify acupuncture method and various indications for the Sifeng points treatment. Based on this study, there is a need for the clinical application and related researches on the Sifeng points in children in Korea. In addition, the treatment location of Sifeng point should be standardized.

Background: Prostatitis, one of the most common diseases of the prostate, is a complex disease with various clinical features. This study aims to analyze the utilization and prescribing patterns of antibiotics in Korean patients with prostatitis between 2008 and 2015. Methods: We used the National Health Insurance Database complied from the Health Insurance Review and Assessment Service (HIRA). The outcomes included the number of claims, number of patients, medical cost, and length of stay for each year. In addition, the prescribing patterns of antibiotics, including fluoroquinolone, and low-dose use of ciprofloxacin and levofloxacin were investigated. Results: The total number of patients and medical cost increased by 9.5% and 51.7% from 2008 to 2015, respectively. Most prostatitis patients were classified as chronic prostatitis patients. The prescribing proportion of antibiotics for chronic prostatitis outpatients decreased from 71.0% to 66.9% from 2008 to 2015, and fluoroquinolone accounted for more than half of the total antibiotics. Over 80% of prescription of levofloxacin and ciprofloxacin was identified to be for low-dose use. Conclusion: Most of the patients with prostatitis experienced pain relief and condition improvement after antibiotic treatment; however, chronic prostatitis and chronic pelvic pain syndrome recur easily. Therefore, active disease management and further studies are needed to enhance our understanding of effective treatment for prostatitis.

Objectives We aimed to examine health-related economic analysis of available interventions on idiopathic short stature (ISS). Methods Eight studies were reviewed from English, Korean, and Chinese databases which were published up to December 24, 2020. Effectiveness, utility, and cost data were extracted from the studies and descriptive analysis of the individual studies was conducted Results Five studies were chosen. In the two economic evaluation studies, the incremental cost-effectiveness ratio (ICER) of growth hormone (GH) treatment was presented by performing cost-effectiveness analysis based on the deterministic decision tree approach for the GH and untreated group. Final adult height and direct medical costs were analyzed as effectiveness and cost outcomes. In 1 review article, an ICER of GH was presented based on systematic review on the effects of the GH treatment. In the two clinical trials, the effectiveness and cost of the 12 months Oriental medicine combination treatment were presented in comparison with the GH treatment alone. There were no literatures that provided utility data of available intervention on ISS. Conclusions The results of this study will be used as basic data for the economic analysis of Oriental medicine treatment on ISS in the future.

Objectives: A hospital is a complex building that serves many different purposes. The indoor environment in a hospital plays a major role in patient well-being and the work efficiency of the hospital staff. This study was conducted to evaluate overall comfort in two major hospitals over the course of one year. Methods: Various indoor environmental conditions were measured in two general hospitals for one year (April 2014 to April 2015). Monitoring alternated between the hospitals at one month per respective monitoring session. The indoor air temperature, relative humidity (RH), mean radiant temperature and air velocity were measured in order to calculate the predicted mean vote (PMV). Carbon dioxide concentration, noise level and illumination level were concurrently measured and applied to the overall IEQ acceptance model for the hospitals (IEQh). Results: The IEQh at the two general hospitals was different at five spaces within a building. The IEQh for summer and winter were significantly different. Real-time IEQh demonstrated that indoor comfort was affected by the hospital s operating hours due to operation of the HVAC system. The percentage of indoor comfort in the hospitals was higher using PMV than IEQh. Conclusion: IEQh in the hospitals was different at locations with different purposes. Indoor comfort assessment using IEQh was stricter than with PMV. Additional research is needed in order to optimize the IEQh model.

The purpose of this research is to know the effects of audio-visual fairy tale program on linguistic Intelligence of elderly people. AV(audio-visual) program is using visual images to maximize the effect of tracing an image in the brain. Sound effect with images which is not only another a means of communication helps elder to remember and concentrate on the linguistic intelligence program but also make them feel familiar of the program. The age between sixties and eighties is ideal for this inquiry. Episode 1 is consisted of twenty-four basic words which help elders who have a low level of education. Episode 2 is consisted of advance task compare to Episode 1 using some of difficult vocabulary or complicated story. Episode 3 is consisted of the question can be inferred by the memory from Episode 1 and Episode 2. Two types of test programs which are AV program and Audio program are applied to elders what for knowing which one is more effective their linguistic intelligence. Both test programs categorized by immediate recall delayed recall story-multiple choice and vocabulary-multiple choice. As the result of the tests according to the statistic AV program was more effective and efficient than the Audio program and AV program made elders were encouraged. AV program is effective and efficient method to improve linguistic intelligence for seniors. From now on this hypothesis needs to verify more with a systematic approach and develop more AV programs to maximize efficiency of Linguistic Intelligence for elderly people. 본 연구는 영상 프로그램의 극대화된 표상작용 효과를 통해 뇌에 강도 높은 잔영을 남겨 노인인지능력 향상에 도움을 주고자 하는 의도에서 시작되었다. 노인들에게 언어인지 검사를 시행할 경우 검사 자체에 거부감을 나타내는 경우가 있는데 영상과 음향전달방식이 가지는 복합성이 기억력과 집중력에 도움을 줄 뿐만 아니라 노인인지검사에서도 거부감을 주지 않는 방법일 것이라는 가정 하에 연구를 시작하였다. 연구대상은 60세에서 80세 사이의 노인들로 구성되었고 무학력 노인들도 쉽게 접하고 기억 할 수 있는 전래동화로 구성된 에피소드-1과 그보다 어렵고 이야기 흐름과 어휘들을 기억하기 쉽지 않은 에피소드-2 그리고 에피소드-1과 에피소드-2 를 듣고 나서 유추 결말을 이끌어 낼 수 있는 에피소드-3로 구성하였다. 검사프로그램을 영상검사프로그램과 음성검사프로그램으로 분류하여 노인들이 어느 것을 쉽게 오래 인지를 할 수 있는지 즉각회상 지연회상 이야기재인 단어재인으로 나누어 실험하였다. 그 결과 노인언어인지 검사에서 영상이 음성보다 노인들에게 효율적이고 기억에 강하게 남는다는 것을 알 수 있었으며 진전되는 인지 검사에서 노인들이 자신감을 갖고 임할수 있다는 것과 인지향상에 효과적이라는 것이 입증되었다. 향후에는 이 같은 효과를 극대화 할 수 있는 프로그램 콘텐츠를 심도 있게 개발하는 것이 과제이며 나아가 다양한 영상 프로그램을 영상치료사 노인 상담사 노인 특수치료사 노인 전문 교육가 등이 활용 할 수 있는 방안 역시 고찰되어야 할 것이다.
