To evaluate iron nutritional status of female college students, fasting blood samples were taken from 76 female students of Kangnung National University. Hemoglobin(Hb), hematocrit(Hct), serum iron(Fe), total iron binding capacity(TIBC) and serum ferritin concentrations were measured and transferrin saturation was calculated. Mean values for Hb, Hct, Fe, TIBC, TS and serum freeitin were 13.64+/-1.42g/dl, 40.99+/-4.31%, 103.0+/-33.3 microgram/dl, 395.3+/-9.07 microgram/dl, 26.58+/-9.07%and 26.76+/-17.5ng/ml, respectively. Prevalence of iron deficiency greatly varied by indices from 6.8% when judged by Hct to 26.0% by serum ferritin concentration. The Hb concentration was positively correlated with hematocrit (r=0.5402), serum iron(r=0.2819) and transferrin saturation(r=0.2777)(p<0.05). on the other hand, serum ferritin concentration showed significantly negative correlation with TIBC(r=-0.3196). Two-day dietary intake records were collected from subjects to estimate mean daily iron intake and bioavailability of dietary iron. Mean daily intake of iron was 13.15 mg and heme iron intake was 0.83 mg which was 6.4% of total iron intake. Total absorbable iron calculated by the method of Monsen was 1.27 mg and bioavailability of dietary iron was 9.6%. In the light of high prevalence of iron deficiency based of serum ferritin concentration and low bioavailability of iron in the diet, guidelines about diet should be made to increase the content and bioavailability of iron in the diet if female college students.

The Korean Journal of Sports Medicine 2023;41(1):27-35
Purpose:
This study aimed to investigate the association between sedentary behavior and generalized anxiety disorder (GAD) according to changes in physical activity after coronavirus disease 2019 (COVID-19) in Korean adolescents.
Methods:
This study included 52,723 South Korean middle and high school students who had obtained a complete Korea youth risk behavior survey, 2021. To identify the association between sitting time and GAD (GAD-7 scale≥10), odds ratio (OR) and 95% confidence interval (CI) were calculated using complex sample logistic regression analysis (p<0.05).
Results:
After adjusting for confounding variables, higher sitting time was associated with higher GAD risk (OR [95% CI]: 5–10 hours, 1.15 [1.04–1.27]; 10–15 hours, 1.23 [1.12–1.35]; ≥15 hours, 1.28 [1.15–1.43]). In adolescents whose physical activity has not changed or has increased after COVID-19, as the sitting time increased, the OR (95% CI) of GAD increased (5–10 hours, 1.15 [1.02–1.31]; 10–15 hours, 1.20 [1.07–1.35]; ≥15 hours, 1.35 [1.17–1.54]). But, not in adolescents whose physical activity has decreased after COVID-19.
Conclusion
We observed the independent associations between sedentary behavior and GAD, and sedentary behavior and GAD are associated by change in physical activity after COVID-19 among adolescents. Therefore, in the pandemic era reducing sedentary behavior and increasing physical activity is necessary for adolescents to enhance mental health and decrease the case of GAD.

Objectives:
:This study aimed to examine the mediating effect of sleep quality and interpretation bias for ambiguity in the relationship between hopelessness and suicidal ideation in psychiatric patients.
Methods:
:A total of 231 psychiatric outpatients and inpatients completed the Beck Hopelessness Scale, Pittsburgh Sleep Quality Index, Ambiguous/Unambiguous Situations Diary-Extended Version, and Ultra-Short Suicidal Ideation Scale. Data analysis was conducted using regression analyses and bootstrap sampling.
Results:
:The results of this study showed that hopelessness had a direct effect on suicidal ideation, and that sleep quality and interpretation bias for ambiguity mediated the association between hopelessness and suicidal ideation. Moreover, there was a significant double mediating effect of sleep quality and interpretation bias for am-biguity on the relationship between hopelessness and suicidal ideation.
Conclusions
:These results suggest that it is important to consider both sleep quality and interpretation bias for ambiguity to prevent hopelessness from leading to suicidal idea. These results suggest that considering both sleep quality and interpretation bias for ambiguity may be important in preventing hopelessness from leading to suicidal ideation.

The Korean Journal of Sports Medicine 2023;41(4):216-224
Purpose:
Our primary aim was to elucidate the association between relative grip strength levels and the risk of developing diabetes, utilizing longitudinal data.
Methods:
A total of 1,935 participants in this study comprised general adults aged 51 to 81 years, who had engagedin the survey both in 2013–2014 and during the subsequent follow-up in 2019–2020. The criteria for diagnosingdiabetes included receiving a diabetes diagnosis and treatment. grip strength was converted into relative grip strength by dividing it by body mass index. To validate the relationship between the interaction of relative grip strength and resting heart rate and its impact on risk of developing diabetes, a proportional hazards Cox regression model was used.Subsequently, we computed the hazard ratio (HR) and 95% confidence interval (CI) for risk of developing diabetes.
Results:
After adjusting for various confounding variables, we observed a significant 46% reduction in the risk of developing diabetes in the high relative grip strength group compared to the low relativegrip strength group (HR,0.54; 95% CI, 0.36–0.80). However, upon additional adjustment for waist circumference, no significant findings couldbe yielded. Furthermore, we found significant differences the relationship between relative grip strength, resting heart rate, and the risk of developing diabetes among different groups.
Conclusion
This study investigates the relationship between relative grip strength and incidence of diabetes, attributed to the accumulation of body fat. Notably, both resting heart rate and relative grip strength emerge as predictive indicators for assessing the risk of diabetes development.

Purpose:
The purpose of the present study was to investigate the relationship between changes in sitting time (ST) with the risk of developing metabolic syndrome.
Methods:
This study examined 2,814 adults aged 40 to 69 years who participated in the Korean Genome and Epidemiology Study, a community-based cohort study, for a total of 10 years. Changes in ST were assessed using the results obtained from physical activity questionnaires completed during the baseline and follow-up surveys. The diagnosis of metabolic syndrome was classified according to the criteria established by the International Diabetes Federation. We conducted survival analysis by the multivariate extended Cox regression model. The significance level for all analyses was set at p< 0.05.
Results:
We compared the newly ST group with ST less than 7 hours in the baseline and more than 7 hours in the first follow-up to the consistently non-ST group with ST less than 7 hours in both the baseline and the first follow-up. In this comparison, we found that the hazard ratio (HR) for the incidence of metabolic syndrome increasedby 33% (HR, 1.33; 95% confidence interval [CI], 1.02–1.74) for changes in total daily sedentary time and by 47% (HR, 1.47; 95% CI, 1.13–1.92) for changes in weekday sedentary time in the newly ST group.
Conclusion
Changes in ST are associated with the risk of developing metabolic syndrome. These findings can serve as fundamental data for further research on the relationship between changes in ST, and the occurrence of metabolic syndrome.
7.Resin bonded fixed prosthesis for single tooth restoration: A case report.
The Journal of Korean Academy of Prosthodontics 2017;55(3):325-330
In the case of single tooth replacement, a fixed prosthesis or a dental implant is the treatment option commonly selected as first choice. However, any amount of sound tooth structure should be removed to prepare the abutment teeth for full coverage retainer. The adjacent tooth damage can be avoided placing a dental implant. However, depending on the patient's oral condition and any other circumstances, it may be impossible or delayed. In this case resin bonded fixed partial denture was selected as an alternative that can restore single tooth loss without much tooth structure removal to the young patients and the patients with gingival recession. We report these patients were satisfied with esthetic and function.

8.Assessment of the Intake and Availability of Dietary Iron and Nutrition Knowledge in Pregnant Women.
Korean Journal of Community Nutrition 1998;3(1):53-61
This study was designed to estimate mean daily iron intake and its bioavailability and to assess nutrition knowledge for 144 pregnant women in the last trimester. Serum ferritin concentration was analyzed to estimate their iron stores. Dietary intakes of iron(heme iron and nonheme iron), the amounts of MPF(meat, poultry and fish) and ascorbic acid were assessed by modified 24-hr recall method. The food frequency questionnaire was used to assess subjects usual food consumption patterns. The mean value of serum ferritin was 21.3+/-15.3ng/ml and 26.4% of the pregnant women had a serum ferritin level<12ng/ml(i.e. depleted iron stores). The mean daily intake of total orin in the pregnant women was 56.5%(17.0 mg) of RDA and heme iron intake was 0.94 mg which was 5.5% of total iron intake. Total absorbable iron calculated by the method of Monsen was 2.41 mg and bioavailability of dietary iron was 2.41%. Food frequency test score of meats group was positively correlated(r=0.443) with the bioaavailability of dietary iron. The mean score on the nutrition knowledge test of subjects was 12.76(out of a possible 20 points). These results indicate that the nutritional iron status may be improved by increasing either the amount of iron in the diet or its availability.

Korean Journal of Rehabilitation Nursing 2012;15(2):117-125
PURPOSE: The purpose of this study was to develop and validate of a knowledge scale for lymphedema in patients with breast cancer. METHODS: 34 preliminary items were made according to literature review, then verified content validity, construct validity, and reliability of the scale. 28 items among them were confirmed through content analysis by 4 experts. After a preliminary test, a survey for 156 breast cancer patients was performed for confirming construct validity and reliability. The data were analyzed using factor analysis, independent t-test, and KR-20. RESULTS: This scale had 28 items consisting of 2 categories: prevention and self-care of lymphedema. Construct validity was confirmed by known-group technique because there were some categories consisted of just one or two items, and some mismatches between categories and items in factor analysis. Women who were educated about lymphedema scored significantly higher than women who had not (t=-3.92, p<.001). Reliability was appropriate (KR-20=.81). A percentage of correct answers was 74.6%, but it was from 31.8% to 96.1%. CONCLUSION: The study shows that this scale is reliable and valid to measure the knowledge of lymphedema. This scale can be effective to assess and educate the patients with breast cancer.

10.Research Trends and Prospects of Medical Anthropology: Concepts and Their Intersection with History of Medicine
Korean Journal of Medical History 2020;29(3):903-958
This study explores the history of research in Medical Anthropology by examining key concepts in the field with a focus on their relevance with findings from the field of History of Medicine. The concepts discussed in this paper are Medical Pluralism, Social Suffering, Biopolitics, and Care. Since concepts internalize the ethnographic gaze, what this paper aims is to trace the development of the gaze on a historical axis. Although concepts come from a specific historical period, they are by no means exclusive to it, as they are revisited again and again through various discourses. In other words, the insight that the previous meaning of a concept has grasped is instilled into the revisited concept. In this way, concepts engage in historical communication, create intersections with the interests of History of Medicine. By discussing these intersections with each concept, this paper suggests the complementary roles of the two fields and their approach to historical events and phenomena.
