Menopausal symptoms can persist or worsen even years after menopause and affect women's quality of life. We investigated whether menopausal symptoms were alleviated through a marine healing program and if sea mustard intake additionally benefits these symptoms. A total of 42 menopausal women self-selected to participate as the marine (n = 22) or city group (n = 20). The marine group participated in a 5-day marine healing program consisting of a balanced diet, exercise, and mind-body practices using ocean resources. The city group continued one's daily routine without any intervention. Within the marine group, participants were randomly assigned to consume sea mustard (Undaria pinnatifida) (15.4 g dry weight/day; n = 11) or control (n = 11). Changes in menopausal symptoms were measured using the Menopause Rating Scale (MRS) before, immediately after, and 2 weeks after the end of the marine healing program. The city group completed the MRS at baseline and on day 20. Within subject differences of menopausal symptoms between baseline and immediately after the marine healing program were assessed using paired t-test. Intervention effects were assessed by mixed analysis of variance. Somatic, psychological, and urogenital symptoms were immediately alleviated after the marine healing program. No effect of sea mustard was detected in the marine group. After 2 weeks, the effect of marine healing persisted in physical and mental exhaustion only. A 5-day integrated marine healing program, but not additional sea mustard intake, temporarily alleviated menopausal symptoms. The reduction in physical and mental exhaustion after marine healing can be maintained for 2 weeks.

본 연구는 국내외 에너지 절감 프로그램에서 사용자의 에너지 절감 행동을 유도하는 9 가지 요소(Yun et al.) 중 보상(Reward) 요소의 적용 수준이 미비함을 발견하였다. 보상 전략의 적용을 높이고 적절히 활용하기 위해 보상 요소에 초점을 맞춘 이 논문은 마케팅에서 다뤄지는 고객보상프로그램을 기준으로 하여 실용적, 쾌락적 보상유형과 즉시, 지연의 보상 시점을 새롭게 정의한다. 재정의된 보상 유형과 보상 시점에 따라 국내외 에너지 절감 프로그램의 사례 조사 및 분석을 통해 현 프로그램의 보상 요소의 적용 현황을 살펴보았다. 그 결과, 보상 시점으로는 사용자의 에너지 사용량과 노력이 축적되어 보상되는 지연 보상이 대체로 사용되었고, 보상 유형으로는 실용적 보상과 쾌락적 보상이 적절히 혼합된 형태로 제공되는 것이 대부분이었으나 모든 사례에서 쾌락적 보상을 제공하고 있었다. 이러한 연구 결과는 에너지 절감행동 유도를 위한 보상프로그램 설계의 이론적 기틀을 제시한다. 그러나 보상 유형과 시점을 더 세부적으로 나눠 연구를 진행할 수 있는 가능성이 있어 후속 연구로는 최종 목표 중간에 보상물을 제공하는 중간 보상에 대한 연구와 에너지 절감행동이 이루어지지 않았을 때 제공하는 부정적 보상을 통해 지속적인 에너지 절감 행동을 위한 프로그램 전략을 제시하는 연구가 필요하다. There is a study that the application of reward factor is incomplete in the domestic and foreign energy savings program among the 9 factors that promotes the user behavior level in energy savings program, proposed by Yun(2013). So, we redefine hedonic, utilitarian reward and immediate, delayed reward by customer reward program dealt in the marketing field. Through the case studies and analysis of energy saving program, this study recognizes the application of reward types in the current program. As a result, in the rewarding time factors, the accumulated reward that provides compensation after the program is over, are used. And among the types of reward properties, utilitarian and hedonic types were mostly provided together, but hedonic reward type was given in every case study. The result of the study proposes a theoretical foundation to promote user energy saving action, in the designation of reward program. But, the research of middle reward and negative reward should involve the follow-up study.

Yun Ki Wook,Kyung Min Kim,Ye Kyung Kim,Min Sun Kim,Hyuktae Kwon,Mi Seon Han,Hyunju Lee,Eun Hwa Choi 대한의학회 2021 Journal of Korean medical science Vol.36 No.5

Considering the mild degree of coronavirus disease 2019 (COVID-19) in children and the enormous stress caused by isolation in unfamiliar places, policies requiring mandatory isolation at medical facilities should be reevaluated especially given the impact of the pandemic on the availability of hospital beds. In this study, we assessed the usefulness of facility isolation and the transmissibility of severe acute respiratory syndrome coronavirus 2 by infected children to uninfected caregivers in isolation units at a hospital and a residential treatment center in Seoul during August-November 2020. Fifty-three children were included and median age was 4 years (range, 0–18). All were mildly ill or asymptomatic and isolated for a median duration of 12 days. Thirty percent stayed home longer than 2 days before entering isolation units from symptom onset. Among 15 uninfected caregivers, none became infected when they used facemasks and practiced hand hygiene. The results suggest children with mild COVID-19 may be cared safely at home by a caregiver in conditions with adherence to the preventive measures of wearing facemasks and practicing hand hygiene.

Background: Coronavirus disease 2019 (COVID-19) is generally asymptomatic or mild in otherwise healthy children, however, severe cases may occur. In this study, we report the clinical characteristics of children classified as critical COVID-19 in Korea to provide further insights into risk factors and management in children. Methods: This study was a retrospective case series of children < 18 years of age classified as critical COVID-19. Cases were identified by the Korea Disease Control and Prevention Agency surveillance system and medical records were reviewed. Critical COVID-19 was defined as cases with severe illness requiring noninvasive (high flow nasal cannula, continuous positive airway pressure, or bilevel positive airway pressure) or invasive mechanical ventilation, extracorporeal membrane oxygenation (ECMO) or continuous renal replacement therapy (CRRT), between January 20, 2020 and October 7, 2021. Results: Among 39,146 cases diagnosed with COVID-19 in subjects < 18 years of age, eight cases (0.02%) were identified as critical COVID-19. The median age was 13 years (range 10 month–17 years) and male-to-female ratio was 1:1. Three children had underlying diseases; one child has asthma and major depressive disorder, one child had LennoxGastaut syndrome and one child had mental retardation and was newly diagnosed with type 2 diabetes mellitus with the diagnosis of COVID-19. Among the eight children, seven were obese (body mass index range [BMI] median 29.3, range 25.9–38.2, weight-for-length > 97% for infant) and one was overweight (BMI 21.3). All patients had fever, six patients had dyspnea or cough and other accompanied symptoms included sore throat, headache, lethargy and myalgia. Radiologic findings showed pneumonia within 1–8 days after symptom onset. Pneumonia progressed in these children for 2–6 days and was improved within 5–32 days after diagnosis. Among the eight critical cases, remdesivir was administered in six cases. Steroids were provided for all cases. Inotropics were administered in one case. Six cases were treated with noninvasive mechanical ventilator and three required mechanical ventilator. One case required ECMO due to acute respiratory distress syndrome. All cases were admitted to the intensive care unit and admission period ranged from 9–39 days. Among all critical COVID-19 cases < 18 years of age, there were no fatal cases. Conclusion: To develop appropriate policies for children in the COVID-19 pandemic, it is important to monitor and assess the clinical burden in this population.

전현주 ( Hyunju Jun ),이영훈 ( Young Hoon Lee ),윤진영 ( Jinyoung Yun ),허정 ( Jung Hur ) 한국산업조직학회 2020 産業組織硏究 Vol.28 No.4

국제 무역이 급증하면서 전통적인 제조업 생산 단계에서 벗어나 고부가가치 업무에 더 집중하는 다국적 무공장 기업(factoryless goods producer, FGP)이 생겨났다. 본 연구는 공간모형(spatial model)을 이용해 2008~2014년 기간동안 우리나라 도소매 산업 내 FGP의 타기업에 대한 생산성 파급효과를 분석한다. 주요 결과로는 첫째, 동일 산업 내 기업간 네트워크 효과가 존재한다는 것을 보였다. 둘째, FGP가 동일 산업의NFGP(비FGP)에 양의 유의미한 영향을 끼쳤다. 셋째, FGP는 동일 산업의 NFGP에 영향을 받지 않았다. 넷째, NFGP의 매출액 크기가 클수록 FGP의 파급효과가 더 크게 나타났다. 본 연구는 지난 2010년 전후로 인해 발생한 우리나라 도소매 산업의 주요 성장의 요인으로 FGP와 같은 혁신기업의 역할이 있었음을 밝혔다는데 그 의의를 갖는다. With the rapid increase in international trade, multinational factoryless goods producers (FGP) have emerged and they focus on high value-added service activities moving away from the traditional manufacturing stage. This study analyzes the spillover effect of the FGP on other firms’ productivity in wholesale and retail industries of Korea during the period of 2008~2014 using a spatial model. Main findings are as follows. First, there was a network effect between firms in a same industry. Second, FGP had a significantly positive effect on NFGP (non-FGP) in a same industry. Third, FGP was not affected by NFGP in the same industry. Fourth, the larger the sales of NFGP, the greater the spillover effects of FGP was. This study reveals that the activity of innovative firms such as FGP was an important factor in the growth of the wholesale and retail industry during the period of 2008~2014 in Korea.

Burst-Polling-Based Dynamic Bandwidth Allocation Using Adaptive Minimum Guaranteed Bandwidth for EPONs

Lim, Wansu,Yun, Changho,Yang, Yeon-Mo,Lee, Hyunju,Kim, Kiseon IEEE 2009 Journal of optical communications and networking Vol.1 No.7

<P>The enhanced burst-polling dynamic bandwidth allocation (EBDBA) method is proposed to support broadband access networks based on quality of service for Ethernet passive optical networks (EPONs). EBDBA adaptively increases or decreases the minimum guaranteed bandwidth of the three traffic clasess¿expedited forwarding (EF), assured forwarding (AF), and best effort (BE) traffic¿according to the requested bandwidth of an optical network unit. Therefore, network resources are efficiently utilized and adaptively allocated to the three traffic classes for unbalanced traffic conditions. Simulation results using OPNET show that EBDBA outperforms conventional bandwidth allocation schemes in terms of the average packet delay (it decreases the maximum performance range to 68%) and the network throughput (it increases the maximum performance range to 20%) at a given offered load of 1.2.</P>

Objective: The primary goals of the present study were to assess intellectual function in participants with schizophrenia or bipolar disorder (BD) and to investigate the relationships between cognitive decline and the severity of each type of psychopathology. Methods: The present study included 51 patients with schizophrenia and 42 with BD who were recruited from the psychiatry outpatient clinic of Jeju University Hospital between March 2011 and March 2014. The Korean Wechsler Adult Intelligence Scale (K-WAIS) was administered to each of the 93 participants, and they were categorized into two groups based on their current intelligence quotient (IQ) and their estimated premorbid IQ: severely impaired group (SIG) and mildly impaired group (MIG). The Minnesota Multiple Personality Inventory (MMPI) and the Brief Psychiatric Rating Scale (BPRS) were used to assess psychopathology. Results: The SIG schizophrenia participants exhibited significantly higher scores on the frequent (F) and schizophrenia (Sc) subscales of the MMPI, but significantly lower scores on the correction (K) and psychopathic deviate (Pd) subscales compared with the MIG schizophrenia participants. Furthermore, the BPRS scores were significantly higher in the SIG schizophrenia participants relative to the MIG schizophrenia participants. The SIG BD participants had significantly higher F, masculinity-femininity (Mf), paranoia (Pa), and Sc but significantly lower Pd scores compared with the MIG BD participants. Conclusion: The present findings revealed a significant discrepancy between the estimated premorbid levels of cognitive function and current cognitive function in participants with schizophrenia or BD. Moreover, this discrepancy was correlated with severity of psychopathology in both groups.

본 연구에서는 과학교육에서 그 동안 주목받지 못했던 과학언어 및 과학용어에 대한 연구를 체계적으로 수행하기 위한 목적으로 지난 20년간의 과학교과서 텍스트를 한 자리에 모아 과학교과서 말뭉치를 구축함으로써 다각도로 분석 가능한 형태의 언어 자원을 생성하였다. 말뭉치 구축 대상 자료는 6차 교육과정, 7차 교육과정, 2009 개정 교육과정의 초등학교에서부터 고등학교까지 모든 과학교과서를 수집하고 이 가운데 두 개의 출판사에 해당하는 132권에 대한 말뭉치를 구축하였다. 원시말뭉치, 형태주석 말뭉치, 용어주석 말뭉치의 총 3단계로 구축하였다. 최종적으로 구축된 과학교과서 말뭉치를 K-STeC(Korea - Science Textbook Corpus)이라 명명하였다. K-STeC은 과학용어에 대한 의미 구분과 분야가 표지된 의미 주석 말뭉치로서 교육과정, 과목, 학년, 출판사의 서지 정보와 대단원, 중단원, 소단원의 단원 정보, 페이지, 문장번호의 위치 정보와 함께 본문, 탐구활동, 참고자료, 제목 등의 텍스트 구조 정보를 메타정보로 마크업 하였다. 총 3년여에 걸친 연구 기간 동안 언어정보학, 컴퓨터공학, 과학교육학의 세 분야 전문가들의 노하우를 융합하여 새로운 연구 방법을 창출하였고, 다수의 전문 인력들이 투입되어 노동집약적 결과물을 내었다. 본 원고에서는 전체적인 연구 절차와 방법을 조망함으로써 새로운 연구 방법론 및 결과물을 소개하고 향후 과학언어 연구의 발전 가능성 및 결과물의 활용방안에 대해 논의하였다. In this study, the texts of science textbooks of the past 20 years were collected in order to systematically carry out researches on scientific languages and scientific terms that have not been noticed in science education. We have collected all the science textbooks from elementary school to high school in the 6th curriculum, the 7th curriculum, and the 2009 revised curriculum, and constructed a corpus comprising of 132 textbooks in total. Sequentially, a raw corpus, a morphological annotated corpus, and a semantic annotated corpus of science terms, were constructed. The final constructed science textbook corpus was named K-STeC (Korean Science Textbook Corpus). K-STeC is a semantic annotated corpus with semantic classification and classification of scientific terms, together with meta information of bibliographic information such as curriculum, subject, grade, and publisher, location information such as chapter, section, lesson, page, and sentence, and structure information such as main, inquiry activities, reference materials, and titles. Throughout the three-year study period, a new research method was created by integrating the know-how of the three fields of linguistic informatics, computer science and science education, and a large number of experts were put in to produce labor-intensive results. This paper introduces new research methodologies and outcomes by looking at the whole research process and methods, and discusses the possibility of future development of scientific language research and how to use the results.
