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.

박지원,이종환,Park, Jiwon,Lee, Jonghwan 한국반도체디스플레이기술학회 2022 반도체디스플레이기술학회지 Vol.21 No.3

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.

박지원(Park, Jiwon),Brad Shuck,김우철(woocheol kim) 중앙대학교 한국인적자원개발전략연구소 2021 역량개발학습연구 Vol.16 No.4

지난 20년간 HRD분야에서 직원몰입 변인이 크게 주목을 받으면서 다양한 직원몰입 개념적 정의의 혼용, 적합한 측정도구 선정 등 HRD 실무자들은 실질적으로 직원몰입을 조직에 적용하는데 있어서 어려움에 직면하였다. 이에 본 연구에서는 직원몰입 측정도구가 심리측정학 측면에서 어떠한 요인들이 포함되어 구성되었는지, 또한 측정도구들 간 실질적 측정의 신뢰성 및 타당성이 어떠한지 살펴보고자 하였다. 이를 위해 현재 HRD분야에서 가장 빈번하게 활용되는 세 가지 측정도구(UWES-9, JES, EES)를 선정하여 구조방정식을 통한 모델 평가 및 비내포모델 비교방법을 활용하여 측정도구를 분석하였다. 또한 각 측정도구와 직무성과와의 관계를 분석하여 한국 조직의 맥락에서 업무 성과를 실질적이고 타당하게 예측하는지를 분석하였다. 연구목적 달성을 위해 국내 다양한 기업조직에서 근무하는 정규직 종업원 600명으로부터 수집한 데이터를 사용하여 분석하였다. 연구결과, 한국 조직 맥락에서 EES와 JES가 직원몰입을 측정하거나 직무성과와의 관계를 예측함에 있어 측정모델과 구조모델이 모두 통계적으로 유의한 것으로 나타났다. 나아가 모델의 간명성 관점에서는 비내포모델 비교결과 EES가 선호될 수 있는 것으로 나타났다. 이러한 결과를 바탕으로 HRD분야의 이론적·실천적 함의를 기술하였으며, 또한 연구의 한계점을 토대로 향후 연구에 대한 제언을 기술하였다. As employee engagement has received increasing attention in the HRD field over the last two decades, HRD practitioners have faced challenges related to engagement including measurement selection, meaning, and definitional muddling. Thus, in this study, we performed model evaluation of three unique engagement measures (i.e., the UWES-9, JES, and EES). We also compared them one another using a non-nested model comparison approach to understand how each might perform psychometrically and then paired each measure of engagement with job performance to better understand how each would perform as a tool for predicting that outcome. The data collected among 600 full-time employees working in Korean organizations were employed. The results showed that the EES and JES were feasible and valid for measuring employee engagement as well as for predicting job performance. In addition, the investigation of the best fitting model through the comparison of parsimony fit indices indicated that EES and its relationship with job performance can be preferred in Korean organizational settings. Based on the results, theoretical and practical implications for human resource development, limitations, and recommendations for further research are discussed.

인구정책의 통치성 분석 : 저출산 정책과 가족계획사업 비교

박지원(Jiwon Park),김창엽(Chang-yup Kim) 한국보건사회학회 2021 보건과 사회과학 Vol.- No.58

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.

코로나19 이후의 러시아 소비시장 트렌드: 저가시장 확대 및 온라인 활성화

박지원 ( Park Jiwon ) 한국외국어대학교(글로벌캠퍼스) 러시아연구소 2020 슬라브연구 Vol.36 No.4

코로나19의 확산은 글로벌 원자재 가격을 하락시키면서 러시아 경제에 부정적인 영향을 미치고 있다. 산업생산이 둔화되고 실업이 확산되면서 향후 저소득층이 증가할 것으로 보이며 이러한 상황은 당분간 지속될 것으로 예상된다. 저소득층의 증가는 소비시장에서 저가 중심의 시장을 확대시킬 것인데 러시아 내에서 그동안 시장 점유율을 높여왔던 창고형 초저가 할인매장과 유통의 자체라벨브랜드 등의 성장이 더욱 탄력을 받을 것으로 보인다. 코로나19로 인해 온라인 시장의 성장도 두드러지게 나타날 것으로 예상된다. 온라인 시장의 성장은 최근 모바일 중심의 접속 및 결제편의성 향상과 배송 편의성이 빠르게 개선되면서 촉진되었다. 비대면 트렌드가 강화됨에 따라, 러시아 기업들은 온라인 관련 인프라에 투자를 지속하고 있으며 온라인 시장 활성화에 선순환을 일으킬 것으로 보인다. The spread of Corona 19 is negatively affecting the Russian economy while lowering global raw material prices. As industrial production slows and unemployment spreads, the number of low-income groups is expected to increase in the future, and this situation is expected to continue for the time being. The increase in the low-income bracket will expand the low-cost market in the consumer market, and the growth of warehouse-style ultra-low-priced discount stores and distribution self-label brands, which have been increasing their market share in Russia, is expected to gain further momentum. The growth of the online market is also expected to be noticeable due to the Corona19. The growth of the online market has been fueled by the recent rapid improvement in mobile-oriented access and payment convenience and delivery convenience. With the strengthening of the untact trend, Russian companies are continuing to invest in online-related infrastructure and are expected to create a virtuous cycle in revitalizing the online market.

비대면 플립러닝의 효과에 대한 탐색 연구: 학습자 경험 및 인지된 학습성과 분석

박지원 ( Jiwon Park ),박민주 ( Min Ju Park ) 한국실천공학교육학회 2021 실천공학교육논문지 Vol.13 No.2

COVID-19로 인해 대학도 비대면 교육이 진행되고 있다. 이에 플립러닝 적용하고 있는 수업의 경우에도 비대면 체제로 전환하여 운영이 되고 있으나, 새로운 형태의 비대면 플립러닝 수업 방식에 대한 사례 및 효과에 대한 탐색 연구는 아직 부족한 실정이다. 이에 본 연구에서는 비대면 플립러닝 교수 전략의 효과를 살펴보기 위해, FGI 및 설문을 통해 학생들의 학습 경험을 분석하고 교과목 목표 달성 수준을 확인하여, 궁극적으로 효과적인 비대면 플립러닝 수업을 위한 시사점을 제공하고자 하였다. 연구결과, 학습자들은 대체로 비대면 플립러닝 수업방식에서 퀴즈, 팀활동, 그리고 교수자의 질의응답 및 피드백 등 상호작용 측면에서 긍정적으로 평가를 하였으며, 사전-사후 학습 달성 정도의 변화에서도 유의한 차이를 보여주었다. 이러한 연구결과를 바탕으로 시사점을 논의하였다. As universities have operated non-face-to-face semesters due to COVID-19, although instructors applying flipped learning to their classes also have changed it into non-face-to-face ways, there is still a lack of exploratory research on effectiveness of the new form of flipped learning. In this study, we explored the effectiveness of the non-face-to-face flipped learning by analyzing students’ earning experiences throughout FGI and survey. By doing so, we sought to provide in-depth insights for successful implications of non-face-to-face flipped learning classes ultimately. The findings showed that many learners positively evaluated non-face-to-face flipped learning in terms of interactions, including quizzes, team activities, and interpersonal interactions (e.g., Q&A, feedback) with professors in non-face-to-face flipped learning classes. The result of the survey also showed significant differences in the pre-posttest regarding learner’s perceived learning achievement. Based on these findings, the implications were discussed.

메커니즘 디자인을 활용한 배 의무자조금 거출기준 분석

The voluntary check-off program for pears in Korea has been in operation since 2004. However, its operation has not reached its full capacity since it collects check-off indirectly from cooperatives, not directly from individual farmers. To enhance the collection and operational efficiency, a mandatory check-off program has been proposed. However, if an enforcement mechanism to prevent farmers from free-riding and a proper level of willingness-to-pay to induce farmers to pay are not devised, the mandatory program will fail. To design an efficient collection mechanism, willingness-to-pay for the check-off has been sur-veyed first. In the survey, it was found that farmers have incentives to lie about their true willing-ness-to-pay and to free-ride. This cheating behaviors make the above maximum collection infeasible. To control the cheating behaviors of the farmers and to design an incentives and participation com-patible check-off collection mechanism, the mechanism design in game theory has been used. According to the mechanism designed, the optimal unit check-off levels are KRW9.79/box for ‘per box’ design and KRW0.28/wrapper for ‘per wrapper’ design. Thus, the total check-offs are estimated to be KRW222million with participation rate of 73% for ‘per box’ program and KRW365million with participation rate of 75% for ‘per wrapper’ program. Thus, ‘per wrapper’ mechanism is found to be more appropriate with larger amount of total check-off and higher participation rate.
