PURPOSE: The purpose of this study was to investigate osteoporosis knowledge, health beliefs, and influencing factors on health behaviors among female college students. METHODS: Using the Osteoporosis Quiz, the Health belief Scale, and the Health Behavior Questionnaire, data were collected from 314 female college students from 4 universities located in Chungcheong providence. RESULTS: The mean scores of knowledge and health belief were 12.7+/-3.81 and 90.9+/-12.66, respectively. There was a statistically significant correlation between osteoporosis knowledge and health belief (p<.001). Also, a statistically significant correlation was found between health belief and health behavior (p<.001). According to the regression model, knowledge, perceived benefit, perceived barrier, family history of osteoporosis, and health interest explained 6.7% of total variance in health behavior. CONCLUSION: Female college students should be taught to be aware of the importance of proper dietary intake and regular exercise as a way to maintain or promote the health of their bones so that they can prevent osteoporosis.

OBJECTIVES: This study was carried out to determine nutritional status of elderly patients in a long-term care hospital according to meal type and eating ability. METHODS: Subjects were 47 female patients aged over 65 (79.3 +/- 7.1 years) who resided in a long-term care hospital in Seoul. Thirty seven patients who ate diet orally were grouped according to meal type (27 general diet and 10 soft diet) and eating ability (26 eating by oneself and 11 eaten with help) and 10 were on tube feeding. Nutritional status was determined by food consumption and mid-arm circumference. RESULTS: The mean adequacy ratios (MARs) of 12 nutrients (protein, calcium, phosphorus, zinc, vitamin A, vitamin B1, vitamin B2, vitamin B6, niacin, folic acid, vitamin C) were 0.687 for general diet, 0.565 for soft diet, 0.680 for eating by oneself and 0.677 for eaten with help, which were significantly lower than 0.982 for tube feeding (p < 0.05 or p < 0.01). The patients on tube feeding had significantly lower % arm circumference compared to those who ate general diet (84.0% vs. 95.4%, respectively, p < 0.05). Nutrients intakes, nutrient adequacy ratio (NAR) and index of nutritional quality (INQ) were not different between meal types as well as eating ability. The most insufficiently consumed nutrients by the patients on diet were folic acid, vitamin B2, and calcium (NAR 0.334~0.453, 0.515~0.539, and 0.516~0.533, respectively). CONCLUSIONS: The results suggested that regardless of meal type or eating ability, the subjects who were on diets in this study might have inadequate intake of folic acid as well as vitamin B2, and calcium, which need to be reflected on menu planning. The measurement of mid-arm circumference presented more risk of malnutrition of patients on tube feeding than those on diets, despite apparently better nutrient consumption.

PURPOSE: This study is to analyze the effects of medical students’ social support and career barriers on career exploration behavior mediated by career decision-making self-efficacy. METHODS: We applied the t-test to investigate the difference among the variables based on gender and admission types. Also, we performed path analysis to verify the effect of perceived career barriers and social support on career exploration behavior with career decision efficacy as a mediator. RESULTS: First, we noted statistically significant gender and admission type difference in social support, career barriers and career exploration behaviors. Second, social support and career barriers were found to influence career exploration behavior as a mediating variable for career decision-making self-efficacy. CONCLUSION: Social support and career barriers as perceived by medical students influenced their career exploration behavior, with their decision-making self-efficacy serving as a full mediator. Therefore, this study has educational implications for career program development and educational training for career decision-making self-efficacy.

Diabetes is often not diagnosed until complications appear, and approximately 30% of people with diabetes may be undiagnosed. Also, complications of diabetes have become a leading cause of impairment of life quality. Therefore efficient approaches to diagnosing diabetes should be developed. The most widely used test for diagnosis of diabetes includes fasting plasma glucose (FPG) and the oral glucose tolerance test(OGTT). The international expert committee has recently recommended the use of HbA1C assay to diagnose diabetes, with a threshold of > or = 6.5%. In 2010, the American Diabetes Association (ADA) adopted the proposal and it became part of the diagnostic criteria of diabetes in the 2010 Clinical Practice Recommendations. Previously, HbA1C had been used primarily to monitor glycemic control among individuals with diabetes. However, over the last decade, the HbA1C measurement has become standardized, facilitating its recognition as an acceptable diagnostic method for diabetes. And several practical considerations favor the use of HbA1C in diagnosing diabetes. The HbA1C does not require the patient to be fasting, can be done at any time that a visit is scheduled, is simpler to perform than the 2 hr OGTT, and is less dependent on the patient's health status at the moment of the blood draw. Also HbA1C is less sensitive to several preanalytical variables, and biological variability is lower than that of both 2 hr post-load glucose and FPG. However, this advantage must be balanced by the low sensitivity of HbA1C, the limited standardization of HbA1C in certain regions, the incomplete correlation between HbA1C and glucose, and risk of misdiagnosis in patient with increased red blood cell turnover, end stage renal disease, with certain forms of hemoglobinopathies.

The culture media for Mycobacterium tuberculosis (MTB) were contrived from both egg-based and agar based ingredients. In 1903, Dorset introduced the first egg-based medium. It was followed by the invention of Lowenstein-Jensen and Ogawa media that contain whole eggs as nutrient and malachite green to inhibit the growth of contaminants. These media have been used worldwide for their usefulness and inexpensiveness. However they have a fundamental disadvantage that the cultivation time for mycobacterial growth takes more than 4 weeks. In 1947, Dubos introduced the first agar medium and followed by the invention of the 7H10 by Middlebrook and Cohn. A powder base of these media contains agar, combination of seven salts, L-glutamic acid, pyridoxine, biotin, and malachite green. This requires the addition of the oleic acid, albumin, dextrose, and catalase (OADC) growth supplement. BACTEC MGIT960 has recently been introduced for rapid cultivation of MTB, which is fully automated liquid culture system with modified 7H9 broth. Agar-based medium developed by Middlebrook has a number of advantages over egg-based medium. One of them is transparency, which enables earlier detection of growing colonies. The major disadvantages of agar media are the high cost of OADC and the need for a CO2 incubator. In conclusion, there is a need for a new agar medium, which can be produced at a lower cost and earlier growth detection. In this review, we introduced the growth promoting factors which can be used as an alternative new growth supplement, cAMP and resuscitation-promoting factor (Rpf). These factors may abrogate a lag in adaption of the bacilli in culture media.

PURPOSE: The purpose of this study was to explore the experiences of nursing college students who attended delivery practices at midwifery clinic. METHODS: This was a qualitative study using focus groups. Data were collected by group interviews with a total of 12 students who observed natural childbirth at midwifery clinic. Data were analyzed through Colaizzi's method in which meaningful statements were extracted. RESULTS: The meanings of experiences were identified five theme clusters from thirteen themes and thirty-one sub-themes. The five theme clusters were 'ultimate process of natural childbirth', 'allowed birth', 'role recognition of the midwife', 'positively changed perception', and 'barriers'. CONCLUSION: This study showed that observation of delivery at midwifery clinic was helpful for nursing students in terms of positive impression about natural childbirth with maternal and baby being centered. Nursing students expressed value and concern about delivery at midwifery clinic. Further in-depth study of natural childbirth in terms of husband and family perspective is required. For quality improvement of maternity nursing care, natural childbirth process needs to be included in nursing care at hospitals as well as students' clinical practicum.

PURPOSE: Troglitazone (TRO) is a peroxisome proliferator-activated receptor gamma (PPARgamma) agonist. TRO has antiproliferative activity on many kinds of cancer cells via G1 arrest. TRO also increases Cu2+/Zn2+-superoxide dismutase (CuZnSOD) and catalase. Cell cycle, and SOD and catalase may affect on radiation sensitivity. We investigated the effect of TRO on radiation sensitivity in cancer cells in vitro. MATERIALS AND METHODS: Three human cervix cancer cell lines (HeLa, Me180, and SiHa) were used. The protein expressions of SOD and catalase, and catalase activities were measured at 2-10 microM of TRO for 24 hours. Cell cycle was evaluated with flow cytometry. Reactive oxygen species (ROS) was measured using 2',7'-dichlorofluorescin diacetate. Cell survival by radiation was measured with clonogenic assay. RESULTS: By 5 microM TRO for 24 hours, the mRNA, protein expression and activity of catalase were increased in all three cell lines. G0-G1 phase cells were increased in HeLa and Me180 by 5 microM TRO for 24 hours, but those were not increased in SiHa. By pretreatment with 5 microM TRO radiation sensitivity was increased in HeLa and Me180, but it was decreased in SiHa. In Me180, with 2 microM TRO which increased catalase but not increased G0-G1 cells, radiosensitization was not observed. ROS produced by radiation was decreased with TRO. CONCLUSION: TRO increases radiation sensitivity through G0-G1 arrest or decreases radiation sensitivity through catalase-mediated ROS scavenging according to TRO dose or cell types. The change of radiation sensitivity by combined with TRO is not dependent on the PPARgamma expression level.

PURPOSE: This study aimed to examine the factors associated with behavior that reduces exposure to environmental hormones among nursing students.METHODS: Data were collected from 160 nursing students in D and B cities, using self-report questionnaires. Data were analyzed using SPSS 22.0, and the analyses included descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient test, and stepwise multiple regression.RESULTS: Behavior that reduces exposure to environmental hormones differed significantly in terms of the participants' knowledge about environmental hormones. Behavior that reduces exposure to environmental hormones was negatively correlated with knowledge of environmental hormones, attitude towards pro-environmental behavior, and environmental self-efficacy; these factors were significant predictors of behavior that reduces exposure to environmental hormones, and accounted for 27.0% of the variance.CONCLUSION: Environmental self-efficacy was identified as the most significant factor affecting behavior that reduces exposure to environmental hormones in nursing students. Therefore, it is necessary to develop programs to improve pro-environmental behavior and environmental self-efficacy in nursing students.

Increased anterior teeth mastication following posterior teeth loss leads to greater anterior occlusal force. It may cause greater attrition of anterior teeth, traumatic force occlusion (TFO), also often followed by antagonist extrusion and occlusal disharmony. This clinical report describes the treatment for a 67-year-old female patient diagnosed with loss of both maxillary and left mandibular posterior teeth, severe attrition of maxillary and mandibular anterior teeth and extrusion of multiple teeth. A diagnostic cast was mounted on articular in centric relation (CR) position to evaluate vertical dimension (VD) and interspace. To provide adequate space for the prosthetic reconstructions, VD was increased by 3 mm on the anterior pin. And then diagnostic wax-up was completed upon that VD. Wax-up was converted to provisional restorations and verified in the patient's mouth and the final restorations were delivered. Clinical follow up examination held 3 months after temporary restoration owing to changes in vertical dimension revealed proper function in mastication without evidence of temporo-mandibular joint (TMJ) disorders. This clinical report presents successfully restoring severe attrition case with increasing vertical dimension resulting in satisfaction in esthetics and function.
