With the expansion in the use of DC power systems and increased need for system maintenance, the development of measurement devices for maintenance requires high stability. Of the different kinds of DC current measurement devices, the single-shot measurement device causes the input signal of the current measuring unit to initially generate a high inrush current. The high inrush current flows into the signal processor of the meter, shortening the life of the internal fuses and causing failure. Therefore, in this study, the I²t value for increasing the durability of the fuse is designed using the available wire diameter. Operating characteristics for 210~400% over-current of the rated current, which is relatively low over-current, are realized by the plating of low melting tin metal. As a result, a method of designing a fuse element for a DC power supply, which improves the safety of the DC current measurement device by blocking the failure caused by the inrush current, is presented.

Objectives : This study analyzed domestic case reports of syndrome differentiation and herbal medicine treatment for tic disorder published from 2000 to 2018 and aimed to seize the latest trend of Korean herbal medicine treatment according to syndrome differentiation. Methods : We searched herbal medicine treatment of tic disorder through five major Korean academic literature databases; NDSL, KTKP, KISS, RISS, DBPIA. Results : 12 articles were included in this study from 49 articles. These studies were analyzed by year, evaluation criteria, Korean treatments, treatment effects, syndrome differentiation, herbal medication, duration of medication, and type of herbal medicine. Treatment results were assessed by YGTSS. Most cases accompanied Korean integrative treatments and only one case report used herbal medicine alone. Most common type of syndrome differentiation for patients was spleen. Duration of medication varied according to each case and decoction was the most used type of herbal medication. Conclusions : It has been reported that herbal medicine treatment according to the syndrome differentiation could be effective in treating tic disorder. This study suggests that additional studies will be required to justify classification of syndrome differentiation and the sole effectiveness of herbal medicine on tic disorder.

Fresh water is very unevenly distributed on Earth. As global warming intensifies, fresh water is becoming increasingly scarce, posing a serious threat to the worlds sustainable development. In response, the United Nations has identified freshwater scarcity as SDG-6 to be addressed. Collecting water from the atmosphere is being discussed worldwide as a technology that can solve this problem, called Atmospheric Water Generation(AWG). In this paper, we looked at AWGs patent application trends by country, technology, and applicant with patent analysis. In addition, based on the core patents selected by technology through quantitative and qualitative evaluation, we looked at AWG characteristics, patent application trends, and technology changes by technology. AWG has been applied in various structures so that it can be applied in various situations. In order to maximize condensate production over time, it was found that various principles were applied for equipment or systems with material and performance development applied. Through this paper, we hope that AWG technology will be actively developed in Korea by raising awareness of AWG to companies and researchers in related fields.

119구급대원의 정신과적 응급환자 대응실태와 개선방안

이예지(Ye-Ji Lee) 국립소방연구원 2020 소방안전연구 Vol.1 No.1

오늘날 정신건강 문제는 흔한 질병이 되고 있으며 사회적 관심도 높아지고 있다. 이에 본 연구는 국내 119구급대원의 정신과적 응급환자 대응실태를 파악하여 개선방안을 제시하고자 했다. 119구급활동일지 분석과 119구급대원 대상 설문조사를 실시한 결과 119구급대원은 정신과적 응급환자를 대응하는 순간부터 병원에 도착하여 인계하는 모든 과정에서 어려움을 겪고 있었다. 이를 개선하기 위해서는 첫째, 응급위기개입서비스를 활성화하고 119구급대원과 경찰관의 교육과 훈련이 필요하다. 둘째, 자·타해 위험이 있는 정신과적 응급환자는 경찰의 구급차 동승 의무화와 119구급대원의 신체 구속을 법적으로 명시해 119구급대원의 안전을 확보해야 한다. 셋째, 정신과적 응급환자를 위한 유휴 병상 확보와 병원의 적극적인 협조가 필요하다. 넷째, 추가 손상이 없는 정신과적 응급환자의 단순 이송은 자가용 등의 다양한 이송수단을 활용한다. 마지막으로 지역 내 경찰, 병원, 소방 관계기관의 협력을 통해 위기사례를 공유하여 한국형 응급개입모델개발을 지속해야 한다. The increase in mental health issues in recent years has increased social interest in mental illnesses. The purpose of this study is to identify the status of 119 paramedics practices regarding response to psychiatric emergency patients and suggest ways to improve them. For this study, Seoul s 119 first aid log in 2019 were analyzed, along with a survey of 119 paramedics working in Seoul. The findings show that the 119 paramedics surveyed experience difficulties throughout the entire process, from their first encounter with psychiatric emergency patients to their arrival at, and transfer to, the hospitals. Improvements on these issues require efforts in five areas. First, emergency crisis intervention service should be reinvigorated. In addition, 119 paramedics and police officers need regular training on how to handle psychiatric patients. Second, when transporting a psychiatric emergency patients who may harm themselves or others, the mandatory accompaniment of police officers and the restraint of paramedics should be specified in the law. Third, hospitals needs to provide full cooperation and secure hospital beds for psychiatric emergency patients. Fourth, in the case of transferring psychiatric patients without severe damage should be carried out with modes of transportation other than the ambulance, including private cars. Finally, the police, hospitals and firefighting agencies within each region should work together to share their experience with crisis response, thereby continuing the efforts to develop Korean-style emergency crisis intervention models.

The purpose of this study is to analyze the heating and cooling energy demand according to the thermal performance changes in building envelope by retrofits. Previous study’s result showed that the annual total energy consumption decreased as the envelope thermal resistance improved, but the cooling energy use increased when window and wall is replaced with latest standard. This is because the high internal heat gain level of the school buildings and the internal heat cannot escape through window and wall when the envelope thermal performance is improved. In order to verify this assumption, the changes of thermal performance according to the envelope changes were analyzed by simulation. As a result, the cooling load increased with the improvement of the thermal performance of building envelope in old school buildings because of the higher internal heat generation level in school buildings.

배당소득 증대세제 및 기업소득 환류세제가 상장기업의 배당정책에 미치는 영향:도입 첫 해의 효과를 중심으로

이예지(Ye Ji Lee),최기호(Kiho Choi) 한국조세연구포럼 2021 조세연구 Vol.21 No.4

[연구목적] 본 연구는 기업이 배당소득 증대세제(이하, 배당세율 인하세제) 및 기업소득 환류세제가 도입된 첫 해인 2015년에 배당을 증가시켰는지를 실증분석하였다. [연구방법] 배당세율 인하세제를 적용받기 위해서는 기업의 3개년 배당성향 평균이 시장평균보다 50%(120%) 이상이면서 현금배당증가율이 10%(30%) 이상이어야 한다. 이에, 본 연구는 기업의 배당성향이 시장평균보다 50% 미만 집단, 50~120% 집단, 120% 이상 집단으로 구분하여 각각의 집단별로 동 제도에 대한 영향이 다른지를 분석하였다. 기업소득 환류세제의 경우 환류세를 부담하지 않기 위해 배당을 증가시켜야 하는 유인이 높은 기업일수록 2015년에 현금배당을 증가시켰는지를 분석하였다. 본 연구는 2015년을 분석대상연도로 하고 435 기업 표본을 이용하였다. [연구결과] 분석결과, 50~120% 집단은 2015년에 현금배당증가율을 유의하게 증가하였지만 50% 미만, 120% 이상 집단 간에는 유의한 차이가 발견되지 않았다. 또한 환류세 부담을 줄이고자 배당을 증가시킬 유인이 높은 기업일수록 2015년에 현금배당이 증가하였다. [연구의 시사점] 본 연구는 기업소득 환류세제 및 배당세율 인하세제의 효과가 처음으로 시행된 해에 배당세금이 기업의 배당정책에 영향을 미친다는 결과를 제시하였다는 점에서 의의가 있다. [Purpose] We examine whether firms increase dividends for 2015 fiscal year, the first year of introduction of the dividend boosting tax(DBT) and corporate earnings circulation tax(CECT) policy. [Methodology] To be subject to DBT, corporate three-year average dividend payout ratio must be 50%(120%) or higher than the capital market average, and the cash dividend growth rate must be 10%(30%) or higher. Considering this, we divide our sample into three groups with dividend payout ratio of less than 50% of capital market average(DIV50%), more than 50 and less than 120%(DIV50%-120%), and more than 120%(DIV120%). And we investigates whether the impact of this tax policy varies by group. In addition, we expect that firms with higher incentive to increase dividends not to pay CECT taxes increase dividends for 2015 fiscal year. To test hypotheses, we use 435 firms in 2015. [Findings] We find that DIV50%-120% group significantly increase cash dividends for 2015 fiscal year, but there are no significant differences between DIV50% and DIV50%-120%. Also, firms with having possibility of paying CECT taxes significantly increase cash dividends for 2015 fiscal year. [Implications] Overall, our results imply that the new dividend tax polices have an influence on corporate dividend decisions.
