이유빈,이상훈 한국협동조합학회 2022 韓國協同組合硏究 Vol.40 No.1

Traditional marketing has been developed for corporative centre but as the market environment changes, the role of consumers is becoming more important. In other words, consumer has changed from passive role for ‘buying’ to partner with corporative for ‘co-producing’, and furthermore, active role for value-seeking. The purpose of this study is to confirm that the mechanism of jointly creating new values through the participation and cooperation of various stakeholders is more sustainable and valuable. For this, our research analyzed the Korea’s representative consumer co-operatives and service dominant logic (SDL) was applied as an analysis frame. SDL is a process in which new values sought by consumers are created through the participation and cooperation of various stakeholders centered on consumers in the value chain. The key factors are operant resources, self participation, horizontal collaboration. As a result of case analysis, three key factors of SDL were continuously identified in the process of the development of consumer co-operatives. In addition, it was found that various stakeholders, centered on consumer co-op members, strengthened cooperation for a common value whenever the co-operative faces a crisis or the size of the organization expands. We expect that SDL will be developed as a useful framework that can support the changed consumer-oriented marketing paradigm. 전통적인마케팅은 기업을 중심으로 발전해왔으나 시장환경이 변하면서 소비자의 역할이 중요해지고 있다. 이에 따라 마케팅은 과거 수동적 소비자중심의 마케팅에서 능동적 소비자중심, 더 나아가 가치추구 소비자중심 마케팅으로 변화하고 있다. 본 연구는 소비자를 중심으로 다양한 이해관계자들의 참여와 협력을 통해 공동으로 창출되는 가치가 지속가능한 경쟁우위를 창출할 수 있다는 것을 확인하고자 하였다. 이를 위해 한국의 대표적인 소비자생협을 대상으로 사례분석을 실시하였고 서비스중심논리(SDL)를 분석틀로 적용하였다. 서비스중심논리는 사용자를 중심으로 다양한 이해관계자들의 참여와 협력을 통해 공동으로 창출되는 프로세스를 말하며, 그 핵심요인은 능동적 자원, 자발적 참여, 수평적 협력이다. 사례분석 결과 소비자조합이 발전하는 과정에서 서비스중심논리의 핵심요인 3가지가 지속적・반복적으로 확인되었으며, 조합이 위기에 직면하거나 조직규모가 확장되는 시기마다 소비자조합원을 중심으로 다양한 이해관계자들(actors)이 공통된 하나의 가치를 위해 협력을 강화하는 모습을 확인할 수 있었다. 향후 서비스중심논리가 소비자중심의 변화된 마케팅패러다임을 뒷받침해줄 수 있는 유용한 틀로서 발전될 수 있기를 기대한다.

Background: We assessed the myocardial infarction (MI), stroke, and all-cause death risks during follow-up according to the low-density lipoprotein cholesterol (LDL-C) levels among older adults.Methods: The Korean National Health Insurance Service datasets (2002 to 2020) were used for this population-based cohort study. The hazards of MI, stroke, and all-cause mortality during follow-up were analyzed according to LDL-C level in individuals aged ≥65 years without baseline cardiovascular diseases (<i>n</i>=1,391,616).Results: During a mean 7.55 years, 52,753 MIs developed; 84,224 strokes occurred over a mean 7.47 years. After a mean 8.50 years, 233,963 died. A decrease in LDL-C was associated with lower hazards of MI and stroke. The decreased hazard of stroke in lower LDL-C was more pronounced in statin users, and individuals with diabetes or obesity. The hazard of all-cause death during follow-up showed an inverted J-shaped pattern according to the LDL-C levels. However, the paradoxically increased hazard of mortality during follow-up in lower LDL-C was attenuated in statin users and individuals with diabetes, hypertension, or obesity. In statin users, lower LDL-C was associated with a decreased hazard of mortality during follow-up.Conclusion: Among the elderly, lower LDL-C was associated with decreased risks of MI and stroke. Lower LDL-C achieved by statins in the elderly was associated with a decreased risk of all-cause death during follow-up, suggesting that LDL-C paradox for the premature death risk in the elderly should not be applied to statin users. Intensive statin therapy should not be hesitated for older adults with cardiovascular risk factors including diabetes.

이유빈,김혜원,이정국,Kang Dongwoo,김규리,Jin Sang-Man,김재현,전홍진,Hur Kyu-Yeon 대한당뇨병학회 2024 Diabetes and Metabolism Journal Vol.48 No.1

Background: The effects of psychotic disorders on cardiometabolic diseases and premature death need to be determined in Asian populations.Methods: In this population-based matched cohort study, the Korean National Health Insurance Service database (2002 to 2018) was used. The risk of type 2 diabetes mellitus (T2DM), acute myocardial infarction (AMI), ischemic stroke, composite of all cardiometabolic diseases, and all-cause death during follow-up was compared between individuals with psychotic disorders treated with antipsychotics (<i>n</i>=48,162) and 1:1 matched controls without psychiatric disorders among adults without cardiometabolic diseases before or within 3 months after baseline.Results: In this cohort, 53,683 composite cases of all cardiometabolic diseases (during median 7.38 years), 899 AMI, and 1,216 ischemic stroke cases (during median 14.14 years), 7,686 T2DM cases (during median 13.26 years), and 7,092 deaths (during median 14.23 years) occurred. The risk of all outcomes was higher in subjects with psychotic disorders than matched controls (adjusted hazard ratios [95% confidence intervals]: 1.522 [1.446 to 1.602] for T2DM; 1.455 [1.251 to 1.693] for AMI; 1.568 [1.373 to 1.790] for ischemic stroke; 1.595 [1.565 to 1.626] for composite of all cardiometabolic diseases; and 2.747 [2.599 to 2.904] for all-cause mortality) during follow-up. Similar patterns of associations were maintained in subgroup analyses but more prominent in younger individuals (<i>P</i> for interaction <0.0001) when categorized as those aged 18–39, 40–64, or ≥65 years.Conclusion: Patients with psychotic disorders treated with antipsychotics were associated with increased risk of premature allcause mortality and cardiometabolic outcomes in an Asian population. This relationship was more pronounced in younger individuals, especially aged 18 to 39 years.

Background: The prevalence and incidence of type 1 diabetes mellitus (T1DM) in all age groups and the prevalence of metabolic syndrome in patients with T1DM in Korea were estimated. Methods: The incidence and prevalence of T1DM between 2007 and 2013 were calculated using the Korean National Health Insurance Service (NHIS) datasets of claims. Clinical characteristics and prevalence of metabolic syndrome in individuals with T1DM between 2009 and 2013 were determined using the database of NHIS preventive health checkups. Results: The prevalence of T1DM in Korea between 2007 and 2013 was 0.041% to 0.047%. The annual incidence rate of T1DM in Korea in 2007 to 2013 was 2.73 to 5.02/100,000 people. Although the incidence rate of typical T1DM was highest in teenagers, it remained steady in adults over 30 years of age. In contrast, the incidence rate of atypical T1DM in 2013 was higher in people aged 40 years or older than in younger age groups. Age- and sex-adjusted prevalence of metabolic syndrome in patients with T1DM was 51.65% to 55.06% between 2009 and 2013. Conclusion: T1DM may be more common in Korean adults than previously believed. Metabolic syndrome may be a frequent finding in individuals with T1DM in Korea.

Objectives The purpose of this study is to investigate the current status of registration of interventional studies focusing on children and adolescents in South Korea and the status of Korean medicine interventional studies through Clinical Research Information Service (CRIS). Methods CRIS was used to search interventional clinical researches which were registered from May, 2010 to October, 2018. Key words of ‘child’, ‘children’, ‘adolescents’, ‘infant’, ‘toddler’, ‘elementary school student’, ‘middle and high school’, ‘middle school student’, and ‘high school student’ were used. Results A total of 37 intervention clinical studies were selected. To identify the trends, years of registration in the CRIS, intervention types, disease categories, recruitment status, phase, institutions responsible for the research, consent, compensation and safety investigation were analyzed. Conclusions This study shows the current state of registration of interventional studies in children and adolescents in Korea. Since interventional studies in children and adolescents are essential for providing safe and effective treatment, further interventional studies, Korean medicine interventional studies and ethical considerations are needed.

본 연구는 공학이 내재된 환경에서 이루어지는 대수 교육이 공학만 사용한 환경에서 이루어진 대수 교육보다 효과적이기 위해 공학 환경에서 암산과 지필계산의 역할, 대수연산 결과를 손으로 기록하는 등 절차를 반복하는 것의 가치, 핵심적인 대수 기능의 가치, 즉 테크닉 지식에 대해 새롭게 조명해보았다. 이를 기초로 하여 대수 교육에 있어 수학적 개념과 테크닉 지식 발달을 위해 공학을 어떻게 사용해야 하는지에 초점을 둔 CAS 기반형 과제를 설계하였다. 본 연구는 앞으로 대수 교육에 있어서 과제 설계 및 워크시트 개발에 있어서 바람직한 방향을 제시할 것이다.

Glycemia according to the Use of Continuous Glucose Monitoring among Adults with Type 1 Diabetes Mellitus in Korea: A Real-World Study

이유빈,Minjee Kim,김재현 대한당뇨병학회 2023 Diabetes and Metabolism Journal Vol.47 No.3

Background: We explored the association between continuous glucose monitoring (CGM) use and glycemia among adults with type 1 diabetes mellitus (T1DM) and determined the status of CGM metrics among adults with T1DM using CGM in the real-world.Methods: For this propensity-matched cross-sectional study, individuals with T1DM who visited the outpatient clinic of the Endocrinology Department of Samsung Medical Center between March 2018 and February 2020 were screened. Among them, 111 CGM users (for ≥9 months) were matched based on propensity score considering age, sex, and diabetes duration in a 1:2 ratio with 203 CGM never-users. The association between CGM use and glycemic measures was explored. In a subpopulation of CGM users who had been using official applications (not “do-it-yourself” software) such that Ambulatory Glucose Profile data for ≥1 month were available (n=87), standardized CGM metrics were summarized.Results: Linear regression analyses identified CGM use as a determining factor for log-transformed glycosylated hemoglobin. The fully-adjusted odds ratio (OR) and 95% confidence interval (CI) for uncontrolled glycosylated hemoglobin (>8%) were 0.365 (95% CI, 0.190 to 0.703) in CGM users compared to never-users. The fully-adjusted OR for controlled glycosylated hemoglobin (<7%) was 1.861 (95% CI, 1.119 to 3.096) in CGM users compared to never-users. Among individuals who had been using official applications for CGM, time in range (TIR) values within recent 30- and 90-day periods were 62.45%±16.63% and 63.08%±15.32%, respectively.Conclusion: CGM use was associated with glycemic control status among Korean adults with T1DM in the real-world, although CGM metrics including TIR might require further improvement among CGM users.
