작가의 내러티브 창작을 지원하는 다양한 프로그램들은 일반적으로 작가에게 필요한 정보의 관리와 상업적으로 성공한 내러티브 텍스트에 대한 분석에 주목한다. 이러한 관점에서는 내러티브 창작 과정에서의 독자의 역할이 간과된다. 작가는 독자의 반응이나 기대를 예상하여, 이를 충족시키거나 배반하면서 내러티브를 구성한다. 사건 전개에 따른 독자의 이해도를 확인하고 이를 적절히 조절하는 작가의 활동은 내러티브 전체의 미학적 완성도와 연관되어 있다. 본 논문에서는 서사학의 내러티브 구조 모델과 인지과학의 ‘사건 색인 상황모델’을 이론적 근거로, 독자의 이해와 관련된 내러티브 텍스트의 특성을 시각적으로 확인하고 조절할 수 있는 창작 지원 시스템 설계를 제안한다. 먼저 사건을 기본 단위로 하여 그 속성을 설정하고 내러티브의 두 시간 축에 배열할 수 있는 프레임워크를 설계하였다. 이를 바탕으로 내러티브의 의미적 일관성과 독자의 이해에 영향을 미치는 다섯차원의 연속성을 시각화하고 독자의 인지적 복잡도를 정보처리 요구량으로써 제시하였다. A variety of writing support systems focus on the information management or the feature analysis of the commercially successful narrative texts. In these approaches, the reader’s role in the narrative creating process is overlooked. During a writing work, an author anticipates reader’s response or expectation to the narrative and he/she organizes the narrative either along or against the prediction about readers. Controlling the reader’s comprehension by unfolding events influences aesthetic quality of the narrative. In this paper, we propose a writing support system to visualize and adjust the characteristics of a narrative text related to the reader’s comprehension based on narrative structure model and event-indexing situation model. Firstly, we designed the interactive framework to create events as the primary units of story and arrange them into both story- and discourse-time axes. Using this organization of events, we visualize the continuity in five situational dimensions and the complexity as a measure of information processing needs, which affect the reader’s understanding and the semantic consistency of the narrative.

Hyun Joo Kim,Hyuktae Kwon,Seung-Won Oh,Cheol Min Lee,Hee-Kyung Joh,Youngju Kim,Yoo-Jin Um,Sang Hyun Ahn 대한가정의학회 2015 Korean Journal of Family Medicine Vol.36 No.5

Background: Postmenopausal osteoporosis is a common disease which can cause various morbidity and economic burden. Lactation is known to cause a decline in bone mineral density (BMD), but there are controversies on whether decreased BMD is fully recovered after lactation and whether lactation duration has an influence on postmenopausal BMD. This study was conducted to see whether breastfeeding is associated with postmenopausal bone loss using a highly representative sample of Korean population. Methods: Retrospective cross sectional study was done using data collected from Korea National Health and Nutrition Examination Survey V. The study outcome was BMD measured with dual-energy X-ray absorptiometry and divided into 2 groups: normal or low BMD (T score<-1), and breastfeeding duration was categorized into 4 groups (never, 1st, 2nd, and 3rd tertile). Logistic regression analysis was done to examine the association between lactation duration and BMD. Results: Among 1,694 postmenopausal women (mean age, 63.5±9.1), 85.71% were in low BMD group. Compared to never breastfeeding group, postmenopausal women with longer than 79 months of breastfeeding duration are more likely to have low BMD (adjusted risk ratio [ARR]=1.24; 95% confidence interval, 1.17 to 1.32). As the duration of breastfeeding increases, ARR and risk difference for low BMD also increases (P for trend=0.008). Conclusion: The study results showed that total breastfeeding duration was associated with postmenopausal low BMD. All women planning on breastfeeding should be aware of its risks and should take adequate dietary calcium and vitamin D before, during, and after breastfeeding.

Feasibility and Effectiveness of a Ring-Type Blood Pressure Measurement Device Compared With 24-Hour Ambulatory Blood Pressure Monitoring Device

Huijin Lee,Sungjoon Park,Hyuktae Kwon,Belong Cho,Jin Ho Park,Hae-Young Lee 대한심장학회 2024 Korean Circulation Journal Vol.54 No.2

Backgrounds and Objectives: This study aimed to evaluate the applicability and precision of a ring-type cuffless blood pressure (BP) measurement device, CART-I Plus, compared to conventional 24-hour ambulatory BP monitoring (ABPM). Methods: Forty patients were recruited, and 33 participants were included in the final analysis. Each participant wore both CART-I Plus and ABPM devices on the same arm for approximately 24 hours. BP estimation from CART-I Plus, derived from photoplethysmography (PPG) signals, were compared with the corresponding ABPM measurements. Results: The CART-I Plus recorded systolic blood pressure (SBP)/diastolic blood pressure (DBP) values of 131.4±14.1/81.1±12.0, 132.7±13.9/81.9±11.9, and 128.7±14.6/79.3±12.2 mmHg for 24-hour, daytime, and nighttime periods respectively, compared to ABPM values of 129.7±11.7/84.4±11.2, 131.9±11.6/86.3±11.1, and 124.5±13.6/80.0±12.2 mmHg. Mean differences in SBP/DBP between the two devices were 1.74±6.69/−3.24±6.51 mmHg, 0.75±7.44/−4.41±7.42 mmHg, and 4.15±6.15/−0.67±5.23 mmHg for 24-hour, daytime, and nighttime periods respectively. Strong correlations were also observed between the devices, with r=0.725 and r=0.750 for transitions in SBP and DBP from daytime to nighttime, respectively (both p<0.001). Conclusions: The CART-I Plus device, with its unique ring-type design, shows promising accuracy in BP estimation and offers a potential avenue for continuous BP monitoring in clinical practice.

Vascular Overload Index Predicts Cerebral Small Vessel Disease in a Neurologically Healthy Population

Ki-Woong Nam,Hyung-Min Kwon,Jin-Ho Park,Hyuktae Kwon 대한신경초음파학회 2021 대한신경초음파학회지 (JNN) Vol.13 No.2

Background: Arterial stiffness has been suggested as one of the major pathological mechanisms of cerebral small vessel diseases (cSVDs). In this study, we confirmed this hypothesis by evaluating the association between vascular overload index (VOI), which is a physiologically good indicator of arterial stiffness, and cSVD. Methods: We evaluated participants who visited Seoul National University Hospital Health Promotion Center for health check-ups between 2006 and 2013. VOI was calculated by the following formula: VOI (mmHg)=1.33×systolic blood pressure -0.33×diastolic blood pressure-133.3. cSVDs were measured including white matter hyperintensity (WMH), lacunes, and cerebral microbleeds (CMBs). We quantitatively measured the WMH volume and rated the presence and number of lacunes and CMBs qualitatively. Results: A total of 3,231 participants were evaluated (mean age 57±9 years, male sex 53.9%). In multivariable linear regression analysis, VOI was significantly associated with WMH volume after adjusting confounders (β=0.004, 95% confidence interval=0.002–0.006). VOI also showed a close association with lacunes in multivariable logistic regression analysis (adjusted odds ratio=1.01, 95% confidence interval=1.00–1.02). There was no statistical association with CMBs. In subgroup analysis according to the presence of hypertension, VOI was closely associated with WMH volume/lacunes only in patients without hypertension. In patients with hypertension, these statistical associations disappeared. Conclusion: A high VOI was associated with cSVD in a neurologically healthy population, especially in patients without hypertension. This marker of arterial stiffness could be convenient and useful predictor of cSVD.

Impact of Visceral Obesity on the Risk of Incident Metabolic Syndrome in Metabolically Healthy Normal Weight and Overweight Groups: A Longitudinal Cohort Study in Korea

Yoon Hye Lee,Jiyong Park,Seran Min,Oklim Kang,Hyuktae Kwon,Seung Won Oh 대한가정의학회 2020 Korean Journal of Family Medicine Vol.41 No.4

Background: Although both obesity, measured by body mass index, and visceral obesity are known to be major risk factors of metabolic syndrome and its components, there have been debates on the relative contribution of general obesity and visceral obesity to the development of metabolic syndrome. Methods: We performed a large longitudinal cohort study of 3,093 subjects (age range, 18–65 years) who were metabolically healthy and had a normal weight who received health screenings over a 3-year follow-up period. Cox proportional hazards models were used to estimate the adjusted hazard ratios (HRs) and 95% confidence intervals (CI) for incident metabolic syndrome and its components per sex-specific 1-standard deviation (SD) increase in visceral adipose tissue (VAT) and body mass index. Results: Both obesity and visceral obesity increased the risk of incident metabolic syndrome, but when HR was compared per sex-specific 1-SD, visceral obesity appeared to confer more risk than simple obesity. The HR for 1-SD of body mass index was 1.19 (95% CI, 1.07–1.32; P=0.001) in men and 1.29 (95% CI, 1.10–1.52; P=0.002) in women, while the HR for 1-SD of VAT was 1.29 (95% CI, 1.15–1.44; P<0.001) in men and 1.50 (95% CI, 1.28–1.75; P<0.001) in women. Conclusion: Visceral obesity and obesity were longitudinally associated with an increased risk of incident metabolic syndrome among metabolically healthy adults, and visceral fat accumulation appears to be better predictor of metabolic syndrome.

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.

Discrepancy between Self-Reported and Urine-Cotinine Verified Smoking Status among Korean Male Adults: Analysis of Health Check-Up Data from a Single Private Hospital

Youngju Kim,Yoon-Jung Choi,Seung-Won Oh,Hee-Kyung Joh,Hyuktae Kwon,Yoo-Jin Um,Sang Hyun Ahn,Hyun Joo Kim,Cheol Min Lee 대한가정의학회 2016 Korean Journal of Family Medicine Vol.37 No.3

Background: Enquiry into smoking status and recommendations for smoking cessation is an essential preventiveservice. However, there are few studies comparing self-reported (SR) and cotinine-verified (CV) smoking statuses,using medical check-up data. The rates of discrepancy and under-reporting are unknown. Methods: We performed a cross-sectional study using health examination data from Healthcare System GangnamCenter, Seoul National University Hospital in 2013. We analyzed SR and CV smoking statuses and discrepancies betweenthe two in relation to sociodemographic variables. We also attempted to ascertain the factors associated witha discrepant smoking status among current smokers. Results: In the sample of 3,477 men, CV smoking rate was 11.1% higher than the SR rate. About 1 in 3 participantseither omitted the smoking questionnaire or gave a false reply. The ratio of CV to SR smoking rates was 1.49 (95%confidence interval [CI], 1.38–1.61). After adjusting for confounding factors, older adults (≥60 years) showed an increasedadjusted odds ratio (aOR) for discrepancy between SR and CV when compared to those in their twentiesand thirties (aOR, 5.43; 95% CI, 2.69–10.96). Educational levels of high school graduation or lower (aOR, 2.33; 95%CI, 1.36–4.01), repeated health check-ups (aOR, 1.45; 95% CI, 1.03–2.06), and low cotinine levels of <500 ng/mL(aOR, 2.03; 95% CI, 1.33–3.09), were also associated with discordance between SR and CV smoking status. Conclusion: Omissions and false responses impede the accurate assessment of smoking status in health check-upparticipants. In order to improve accuracy, it is suggested that researcher pay attention to participants with greaterdiscrepancy between SR and CV smoking status, and formulate interventions to improve response rates.

Association between Nutrition Label Reading and Nutrient Intake in Korean Adults: Korea National Health and Nutritional Examination Survey, 2007-2009 (KNHANES IV)

Min-Gyou Kim,Seung-Won Oh,Na-Rae Han,Dong-Ju Song,Jae-Yean Um,Su-Hyun Bae,Hyuktae Kwon,Cheol-Min Lee,Hee-Kyung Joh,홍성우 대한가정의학회 2014 Korean Journal of Family Medicine Vol.35 No.4

Background: Nutrition labels provide various information on the nutrient contents of food. However, despite the recent increase in the interest in dietary intake and expansion of related policies, studies on the association between nutrition label reading and dietary intake are lacking in Korea.Methods: This study analyzed the 2007–2009 KNHANES (Korean National Health and Nutrition Examination Survey) data. To examine macronutrients and micronutrients intake according to nutrition label reading, analysis of covariance was used. Multiple logistic regression analysis was also used to examine the association between adherence to dietary reference intake and nutrition label reading.Results: Nutrition label reading was significantly high among women, youth, and those with high education and high household income. Nutrition label reading was associated with higher intake of calcium and vitamin C in men and the lower intake of calorie, carbohydrates and higher energy ratio of protein in women. Additionally, male nutrition label readers were associated with adherence to dietary reference intake of fiber (odds ratio [OR], 2.00; 95% confidence interval [CI], 1.23 to 3.26) and calcium (OR, 1.26; 95% CI, 1.03 to 1.54). In women, there were no significant differences in the adherence to the dietary reference intake in fat, fiber, sodium, potassium, and calcium according to the nutrition label reading.Conclusion: In men, nutrition label reading was associated with healthier intake of several micronutrients, although this was not observed in women. Consideration for clearly reporting vulnerable micronutrients in nutrition labels is necessary.
