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.

2.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.

3.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.

Journal of Korean Academy of Nursing Administration 2021;27(5):390-398
Purpose:
The purpose of this study was to identify the relationship between career management, organizational justice, and job rotation attitude among tertiary hospital nurses.
Methods:
A cross-sectional descriptive design was used. The participants were 195 nurses with more than one year of experience working at tertiary care hospitals.Data was collected with self-reported questionnaires from April to May 2018. Data was analyzed using SPSS Statistics version 25.0 for windows including descriptive statistics, bivariate analysis, and multiple regression analysis.
Results:
The mean score of career management of participants was 3.14±0.49 (range 1~5), organizational justice was 2.95±0.53 (range 1~5), and job rotation attitude was 4.02±0.97 (range 1~7). There were significant positive correlations among the participants' career management, organizational justice, and job rotation attitude. 37% of job rotation attitude was explained by position, organizational justice, career management, and the frequency of job rotation experience in the regression model.
Conclusion
This study provided the empirical evidence that it is necessary to improve the perception of organizational justice, and to establish a systematic job rotation in order for nurses to positively recognize job rotation.

Journal of Korean Medical Science 2014;29(4):576-580
Owing to the rarity of the disease, epidemiologic information on achalasia is limited. This study aimed to investigate the epidemiology and treatment patterns of achalasia in the population of Korea using a national healthcare database. The diagnostic code K22.0 of the International Classification of Diseases was used to identify cases of achalasia between 2007 and 2011. Treatment modalities for achalasia were identified using the electronic data interchange codes Q7642 or Q7641 for balloon dilation and QA421 or QA422 for esophago-cardiomyotomy. A total of 3,105 patients with achalasia (1,447 men; mean age, 52.5 yr) were identified between 2007 and 2011, indicating a prevalence of 6.29/100,000 (95% confidence interval [CI], 4.94-7.66) during this 5-yr period. A total of 191 incident cases of achalasia (82 men; mean age, 49.5 yr), which were not diagnosed as achalasia in the previous 4 yr, were detected in 2011, indicating an incidence of 0.39/100,000 (95% CI, 0.15-0.63) for that year. During the study period, balloon dilation therapy was performed a total of 975 times in 719 patients, and surgical esophago-cardiomyotomy was performed once per patient in 17 patients. This is the first population-based epidemiologic study of achalasia in Korea.

Korean Journal of Blood Transfusion 2017;28(1):49-57
BACKGROUND: Red blood cell (RBC) transfusion is one of the major treatments for correcting anemia, but its use should be carefully considered because of adverse transfusion reactions and inappropriate usage. Therefore, individual health care facilities have self evaluated their use of transfusion in an attempt to decrease unnecessary procedures. In this study, we evaluated the differences in the minimum hemoglobin (Hb) trigger for RBC transfusion among clinical departments in Severance Hospital. METHODS: We analyzed the electronic medical records of RBC transfusion episodes that were conducted at a Hb level above 8 g/dL from July 2014 to September 2015. We classified these data by clinical department, and considered the overall medical conditions of the patients. The minimum Hb trigger level in this study was defined as the lowest Hb level within 24 hours prior to RBC transfusion. RESULTS: A total of 4,953 RBC transfusion episodes that were conducted at Hb levels above 8 g/dL were analyzed over that period. In general, the minimum Hb trigger level was higher in the operation group than the hemorrhage group. When compared among clinical departments, the department of orthopedic surgery, neurosurgery, rehabilitation medicine, and anesthesiology showed high levels of minimum Hb trigger equal to or greater than 10 g/dL. CONCLUSION: The minimum Hb trigger level differed among clinical departments, with the operation group showing a much higher level of minimum Hb trigger. We hope that these data will be practically applied to establish plans and strategies for managing the appropriateness of RBC transfusions in Korea. In addition, continuous evaluation and transfusion education for clinical departments should be performed.

Annals of Surgical Treatment and Research 2016;90(4):183-193
PURPOSE: To determine CD133+ cells defined as cancer stem cells (CSCs) in colon cancer, we examined whether CD133+ clones in HCT116 demonstrate known features of CSCs like sphere-forming ability, chemodrug-resistance, and metastatic potential. METHODS: Magnetic cell isolation and cell separation demonstrated that <1% of HCT116 cells expressed CD133, with the remaining cells being CD133- clones. In colon cancer cells, radioresistance is also considered a CSC characteristic. We performed clonogenic assay using 0.4 Gy γ-irradiation. RESULTS: Interestingly, there were no differences between HCT116 parental and HCT116 CD133+ clones when the cells comprised 0.5% of the total cells, and CD133- clone demonstrated radiosensitive changes compared with parental and CD133+ clones. Comparing gene expression profiles between sphere-forming and nonforming culture conditions of HCT116 subclones by whole RNA sequencing failed to obtain specific genes expressed in CD133+ clones. CONCLUSION: Despite no differences of gene expression profiles in monolayer attached culture conditions of each clone, sphere-forming conditions of whole HCT116 subclones, parental, CD133+, and CD133- increased 1,761 coding genes and downregulated 1,384 genes related to CSCs self-renewal and survival. Thus, spheroid cultures of HCT116 cells could be useful to expand colorectal CSCs rather than clonal expansion depending on CD133 expressions.

OBJECTIVES: The purposes of this study were to examine the predictive validity of the Cubbin and Jackson pressure ulcer risk assessment scale for the development of pressure ulcers in intensive care unit (ICU) patients retrospectively and to evaluate the reusability of Electronic Medical Records (EMR) data. METHODS: A retrospective design was used to examine 829 cases admitted to four ICUs in a tertiary care hospital from May 2010 to April 2011. Patients who were without pressure ulcers at admission to ICU, 18 years or older, and had stayed in ICU for 24 hours or longer were included. Sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve (AUC) were calculated. RESULTS: The reported incidence rate of pressure ulcers among the study subjects was 14.2%. At the cut-off score of 24 of the Cubbin and Jackson scale, the sensitivity, specificity, positive predictive value, negative predictive value, and AUC were 72.0%, 68.8%, 27.7%, 93.7%, and 0.76, respectively. Eight items out 10 of the Cubbin and Jackson scale were readily available in the EMR data. CONCLUSIONS: The Cubbin and Jackson scale performed slightly better than the Braden scale to predict pressure ulcer development. Eight items of the Cubbin and Jackson scale except mobility and hygiene can be extracted from the EMR, which initially demonstrated the reusability of EMR data for pressure ulcer risk assessment. If the Cubbin and Jackson scale is a part of the EMR assessment form, it would help nurses perform tasks to effectively prevent pressure ulcers with an EMR alert for high-risk patients.
