Objective: In this study, a questionnaire survey was conducted for doctors and patients to obtain basic data necessary for the development of an integrated medical system for idiopathic pulmonary fibrosis (IPF). Methods: Questionnaires were developed separately for doctors and patients through an expert group meeting. The survey subjects were recruited online and offline, and finally, responses from 231 doctors and 59 patients were used for statistical analysis. Results: The most important parts in the treatment of IPF for both doctors and patients were the "improvement of respiratory symptoms," "improvement of quality of life," and "prevention of disease progression." Antifibrotic agents were prescribed at a high rate, and 100% of the specialists in Western medicine (WM) and 45.8% of patients reported experiencing side effects. As for the additional payment costs that patients considered as affordable for an integrated medical system, "under 50,000 won (about 38$)" was reported the most in both doctor and patient groups. With regard to the reasons for their reluctance to recommend an integrated medical system for IPF, specialists in WM responded highly to "uncertain evidence for treatment effectiveness." Regarding complementary and alternative medicine therapies that can be beneficial in patients with IPF, "lifestyle management," "diet management," "herb," "relaxation therapy," and "psychotherapy" were ranked high in both doctor and patient groups. Conclusions: In this study, a questionnaire survey on IPF was conducted to review actual treatment status, analyze shortcomings, and identify considerations for the development of an integrated medical system for IPF in the future.

In this study, two types of thick steel plates are prepared by controlling carbon equivalent and nickel content, and their microstructures are analyzed. Tensile tests, Vickers hardness tests, and Charpy impact tests are conducted to investigate the correlation between microstructure and mechanical properties of the steels. The H steel, which has high carbon equivalent and nickel content, has lower volume fraction of granular bainite (GB) and smaller GB packet size than those of L steel, which has low carbon equivalent and nickel content. However, the volume fraction of secondary phases is higher in the H steel than in the L steel. As a result, the strength of the L steel is higher than that of the H steel, while the Charpy absorbed energy at -40 ℃ is higher than that of the L steel. The heat affected zone (HAZ) simulated H-H specimen has higher volume fraction of acicular ferrite (AF) and lower volume fraction of GB than the HAZ simulated L-H specimen. In addition, the grain size of AF and the packet sizes of GB and BF are smaller in the H-H specimen than in the L-H specimen. For this reason, the Charpy absorbed energy at -20 ℃ is higher for the H-H specimen than for the L-H specimen.

The current-voltage modeling plays an important role in characterizing photovoltaic systems. A solar cell has a nonlinear characteristic with various parameters influenced by the external environments such as the irradiance and the temperature. In order to accurately predict current-voltage characteristics at low irradiance, the artificial neural networks are applied to effectively quantify nonlinear behaviors. In this paper, a multi-layer perceptron scheme that can make accurate predictions is employed to learn complex formulas for large amounts of continuous data. The simulated results of artificial neural networks model show the accuracy improvement by using MATLAB/Simulink.

인구정책의 통치성 분석 : 저출산 정책과 가족계획사업 비교

이 연구는 2000년대 중반 한국의 저출산 정책이 반대 목표로 추진된 1960년대 가족계획사업과 유사한 통치 원리로 작동하고 있다는 문제의식에서 출발하였다. 연구는 이를 규명하고자 사례연구 방법론 절차에 따라 저출산 정책 자료를 분석하여 가족계획사업과 비교하였다. 분석 결과는 다음과 같다. 첫째, 두 정책에는 인구를 국가 위기로 정의하고, 선진국과의 비교를 정당화 근거로 활용하는 발전주의 통치성이 작동하고 있었다. 또한 두 정책은 출산을 비롯한 재생산을 여성이 전담하는 가부장제 안에서 여성을 정책 대상으로 설정하였다. 둘째, 두 정책은 정책 목표에 맞게 특정한 사고와 행동 양식을 유도하고 정당화하는 통치 기술을 활용하였다. 구체적으로 홍보와 교육을 통해 혼인, 출산과 관련한 가치관과 규범의 변화를 유도하였고, 의료서비스, 주거, 세금, 노동시장 정책 등 광범위한 분야에서 출산과 단산에 대한 직간접적인 유인책을 도입하고 변형하였으며, 법률, 행정, 지식 생산을 정책 정당화를 위한 근거로 적극 활용하였다. 마지막으로 두 정책은 성장하는 국가와 정상가족의 존속이라는 정책 목적이 유사했으나 가족계획사업 당시 가정 내 재생산 역할을 전담한 여성이 저출산 정책 시기에는 재생산과 동시에 생산의 역할도 수행하도록 기대되었다는 점에서 개인에 대한 정책 목적은 구분되었다. 연구 결과를 종합하면 저출산 정책에는 가족계획사업 당시의 문제 정의, 통치 기술, 목적이 유사하게 작동했다. 즉 두 인구 정책에는 국가의 지속적 발전을 위해 정상가족 내 여성의 출산이 조절되어야 하는 가부장적 발전주의 통치성이 연속적으로 작동하고 있었다. 이 연구는 인구정책을 오랜 기간에 걸친 통치의 연속선 하에서 이해함을 통해 정책에 대한 이해를 보다 확장했다는 점에서 의의가 있다. 그러나 두 정책을 단면적으로 분석하였으므로 정책에 영향을 미치는 환경과 맥락을 충분히 고려하지 못했다는 점이 한계이다. 이를 위해서는 이해관계자, 자본, 과학 기술 등 두 정책 요소 간의 연속성에 대한 후속 연구가 필요하다. This study started from the question that Low fertility rate policy in mid-2000s operates with a similar governing principle to 1960s Family Planning Program (FPP) promoted in opposite goals. To clarify this, the study analyzed the low fertility policy according to the case study methodology and compared it with FPP. The results are as follows. First, developmental governmentality was working in both policies that defined the current population as a national crisis and used the comparison with developed countries for justification. In addition, the patriarchy set women as the target of the policy in responding to different problems. Second, two policies utilized governing technology that induces and justifies specific thoughts and behaviors to achieve goals. Specifically, through advertising and education, they induced changes in values and norms related to marriage and childbirth. Direct and indirect incentives for childbirth and birth control in various fields such as medical services, housing, tax, and labor market were operated. Law, administration, and knowledge production were actively used for justification. Finally, two policies were similar in terms of ‘developing country’ and ‘normal family’. However, the purpose of policy for individuals was different because women in charge of reproductive roles were now expected to play role in both reproduction and production. To summarize, problem definition, governing technologies, and purpose worked similarly in two policies. In other words, patriarchal developmental governmentality, in which fertility of women in normal families must be controlled for the continuous development of the country, was continuously operating. This study set the current policy under the continuity of population governmentality over a long period of time. However, since two policies were analyzed cross-sectionally, the environment and context affecting the policies were not sufficiently considered. To demonstrate this, following studies are needed on the continuity between policy elements such as stakeholder, capital, science and technology.

2020년 국제조세 분야 판례 회고

박지원(Park, Jiwon) 한국국제조세협회 2021 조세학술논집 Vol.37 No.2

2020년 대법원은 룩셈부르크 집합투자기구가 조세조약상 거주자이자 이자 및 배당 소득의 수익적 소유자로서, 한-룩 조세조약 제28조의 조약 적용제외 대상에도 해당하지 않으므로 국내법인들로부터 수령한 소득에 대하여 조세조약상 제한세율을 적용받을 수 있다고 판시하였다. 카지노 고객 모집 알선 용역을 제공하는 필리핀법인의 국내 고정사업장의 존부와 관련하여서는, 대법원은 동 법인의 국내 고정사업장이 존재하나, 국내 카지노 운영 법인으로부터 받은 수수료 전액이 국내 고정사업장에 귀속된다고 볼 수 없다고 보아 과세처분을 취소하였다. 마지막으로 무수익 자산의 매입에 따른 부당행위계산 부인 적용시 자산의 취득일로부터 매입대금 회수시까지의 매입대금에 대한 인정이자 상당액을 익금산입하는 것이 타당하다고 판단하였다. 본고에서는 위 각 대법원 판결의 요지 및 의의에 대하여 살펴본다. In 2020, the Korean Supreme Court ruled that a Luxemburg investment vehicle, as the ‘resident’ and ‘beneficial owner’ of dividends and interest as set forth in the Korea-Luxembourg Tax Treaty and not subject to exemption according to Article 28 of the same treaty, is eligible for lower treaty tax rates on income received from Korean companies. In a separate case, regarding whether permanent establishment (“PE”) exists for a Filipino company providing agency services for casino customers, the Supreme Court cancelled the tax assessment in question, on the grounds that even though a PE of the Filipino company exists in Korea, the entire income it received from the Korean casino running company cannot be allocated to that PE. Finally, the Supreme Court decided that when applying repudiation of a wrongful calculation on the purchase of unprofitable assets, the deemed interest on the purchase price from the date of purchase until the date of its redemption should be included in the income.

To stably operate EMS(Energy Management System) that systematically manages energy in the building, there is a need for predicting energy consumption and production in advance. In this study, we used hourly observed meteorological data from January, 2018 to December, 2020 provided by the Seoul branch of the Korea Meteorological Administration. The solar altitude data are calculated through the solar angle calculator provided by One Energy. The collected data are converted into available data set by data processing strategy. The correlation analysis between each meteorological data type and solar radiation after one hour proceeded to select the input parameters on the developed model. Selected meteorological data sets are used in the learning stage of the developed LSTM structure prediction model. The predictive performance of each model were analyzed through MAE(Mean Average Error), NMBE(Normalized Mean Bias Error), CV(RMSE)(Coefficient of Variation of Root Mean Square Error), R²(Coefficient of Determination) and computational time. The model with a window size of 24 was selected by performance evaluation criteria. Valid predictive performance of solar radiation after one hour in Busan was derived also from the selected model.
