Purpose: The purpose of this study is to compare the mother's rearing attitude and communication between mobile phone addiction group and non-addiction group in middle school students. Methods: A cross-sectional descriptive study was performed with 574 students from 3 middle schools (1 boy school, 1 girl school, 1 coeducation school) at G-city in Gangwon Province. The data was collected from the 10th to 24th of July in 2010. Statistical analysis of the results was carried out by means, frequencies, chi-square, t-test and multiple regression with SPSS/WIN 18.0 program. Results: There were significant differences in mobile phone addiction group and non-addiction group in regard to sex, school year, grades, mother' age, purpose of mobile phone use, activity after school, phone bill per month. Also There were significant differences in mother's rearing attitude and mother's communication between two groups. Conclusion: Mobile phone addiction among students is not serious, however, possibility of becoming an addict still remains. This study suggests that we have to educate them about proper mobile phone use in advance to prevent them from becoming a mobile phone addict in early stage. Therefore, we need to develop an educational program to prevent mobile phone addiction.

Objective: To compare the blood glucose levels, insulin concentrations, and insulin resistance during the two phases of the menstrual cycle between healthy women and patients with premenstrual syndrome (PMS). Methods: From January of 2011 to the August of 2012, a descriptive cross-sectional study was performed among students in the School of Medicine of Jahrom University of Medical Sciences. We included 30 students with the most severe symptoms of PMS and 30 age frequency-matched healthy controls. We analyzed the serum concentrations of glucose, insulin, and insulin resistance by using the glucose oxidase method, radioimmunometric assay, and homeostasis model assessment of insulin resistance equation, respectively. Results: No significant differences between the demographic data of the control and PMS groups were observed. The mean concentrations of glucose of the two study groups were significantly different during the follicular and luteal phases (p=0.011 vs. p<0.0001, respectively). The amounts of homeostasis model assessment of insulin resistance of the two study groups were significantly different in the luteal phase (p=0.0005). Conclusion: The level of blood glucose and insulin resistance was lower during the two phases of the menstrual cycle of the PMS group than that of the controls.

Purpose: The purpose of this study was to examine quality of life with patients in 12 months after coronary artery bypass graft surgery, compared with general population. Method: A cross-sectional comparative study was designed. Study participants were 90 adults who had undergone CABG surgery (n=45) in experimental group and general population (n=45) in control group. The subjects were asked the questionnaire (SF-36, Short Form-36) regarding the quality of life. The data were analyzed by the SPSS 13.0 program including frequency, percentage, $x^2$ test, t-test and One-Way ANOVA. Results: There were no significant differences in the quality of life between two groups including physical functioning (t=-.938, p=.351), role-physical limitation (t=-.322, p=.748), bodily pain (t=-.938, p=.351), general health (t=-.1418, p=.888), vitality (t=-.816, p=.417), social functioning (t=.720, p=.474), role-emotional limitation (t=-.710, p=.479), mental health (t=-.431, p=.667). Conclusion: Even though patients in experimental group had operation experience, the quality of life examined on the time of 1 year after bypass surgery is similar in that of general population. We suggest the study change the design as examination of quality of life before and after coronary artery bypass graft surgery.

Objective: The purpose of this study was to examined the kinematic relationship and differences through the range of motion (ROM), muscle activity, and vertical ground reaction force (VGRF) during forward and backward lunge movements, which are effective in improving muscle strength and balance ability of the lower extremities, and to provide clinical information on more efficient lunge movements. Design: Cross-sectional study Methods: Fifteen adult males who met the selection criteria were tested for their dominant feet.Forward and backward lunges were then performed, and the ROM, muscle activity, and VGRF were measured for kinematic analysis during the lunge movement.The differences betweenthe forward lunge and backward lunge intervention were examined using a paired t-test. Results: A significant increase in the ROM of the knee and ankle was observed during the forward and backward lunges (p<0.05). In addition, in terms of the muscle activity, the peak values of the vastus medialis oblique (VMO) and VGRF also showed a significant increase in the forward lunge compared to the backward lunge (p<0.05). Conclusions: This study showed an increase in VGRF peak value, knee and ankle ROM, and VMO muscle activity during forward lunge. Based on these results, it is considered necessary to apply differently depending on the direction of progress in consideration of the musculoskeletal situation and physical ability during the lunge movement.

Objectives: Eight Constitution Medicine (ECM) categorizes individuals into eight constitutions based on physiological differences in organ relations and recommends different diets for different constitutions. This study presents a preliminary analysis of the effect of following constitutional food regimens on quality of life and health outcomes for different constitutions. Methods: This cross-sectional, comparative study used subjects recruited from Essen University Hospital Traditional Chinese Medicine Center in Germany. From a convenience sample of 243 Germans, those in the groups Hepatonia/Cholecystonia (n = 95) and Pulmotonia/Colonotonia (n = 26) were analyzed for health outcomes in relation to their dietary habits of either including or avoiding meat. Health outcomes were measured with SF-36, self-reported survey. Results: The two groups had no significant differences in the health outcomes of SF-36. However, subjects in Hepatonia/Cholecystonia who had followed their dietary habit for more than 20 years had significantly better scores on general health, social functioning, mental health, emotional role functioning, and mental component scores than those in Pulmotonia/Colonotonia, regardless of their meat intake. Conclusions: This study established initial groundwork for considering patients' constitutions when evaluating health outcomes and their relation to diet. Further studies are warranted on the effects of regulating food intake according to individual constitution.

Purpose: This study was conducted to compare the characteristics of organizational structure and occupational satisfaction among nurses in general hospital and small to medium-sized hospital and to investigate the affecting factors on their occupational satisfaction. Methods: The study was based on the cross-sectional descriptive survey. A self-report questionnaire was used to collect data from 343 nurses between June and July, 2010. Data were analyzed by ${\chi}^2$-test, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and multiple regression using the SPSS/WIN 14.0 program. Results: Hierarchical structure was dominant in general hospital whereas relationship was highly valued in small to medium-sized hospital. Occupational satisfaction was positively correlated with work environment built on relationship, innovation and tasks. Factors significantly influencing on occupational satisfaction in general hospital included innovative work environment, nurses' income and their health status ($R^2$=40.3%). For the small to medium-sized hospital, they included innovative work environment, satisfaction in life, tasks and professionalism ($R^2$=40.4%). Conclusion: Organizational structure, especially innovative work environment and relationship-oriented attitude had a significant influence on nurses' occupational satisfaction. Therefore, nursing administrators have to develop and consider organizational structure to improve occupational satisfaction.

A cephalometric radiographic cross sectional comparative study was undertaken to investigate craniofacial growth in cleft lip and palate individuals. The material for this study consisted of 43 subjects with operated cleft lip and palate.(29 males, 14 females). The range of age was from 6 years to 12 years. The roentgenocephalometric values of cleft individuals were compared with values of normal individuals reported by Lee. The following conclusions were obtained; 1) The pattern of cranial base of the cleft subjects was almost the same as that previously reported for the normal individuals. 2) Anterio-posterior length of the mandible did not show any significant difference but in the cleft subjects, that of the males was larger than that of the females. 3) The maxilla of the cleft subjects was very retruded and showed very concave profile. 4) Gonial angle of the cleft subjects was very high, especially in the female clefts. 5) The height of ramus was very poor in the cleft subjects. 6) The facial length was almost the same, but the facial depth of the cleft subjects was smaller than that of the normal individuals. 7) Maxillary and mandibular incisors were severely retroclined. 8) The range of values in the cleft subjects was very variable and the female clefts showed more distured growth than the male clefts.

The aim of the present study was to compare measurement precisions of the Oswestry Back Pain Disability Questionnaire (ODQ) and a computer adaptive testing (CAT) method. The ODQ has been regarded as one of the most reliable condition-specific measure for back pain for decades. Cross-sectional study was carried out with two independent convenient samples from two out-patient rehabilitation clinics for back pain ($n_1=42$) and non-back pain group ($n_2=42$). Participants were asked to fill out the ODQ and CAT of International Classification of Functioning, Disability and Health-Activity Measure (ICF-AM). A series of Rasch analyses were performed to calculate person ability measures. The CAT measures had greater relative precision in discriminating the groups than did the ODQ measure in comparisons of the relative precision. The CAT measure appears to be more effective than did the ODQ measure in terms of measurement precision. By administering test items calibrated in a way, CAT measures using item response theory may promise a means with measurement precision as well as efficiency.

Purpose: This study examined differences in perceptions and intention to report on elder abuse between nurses and elderlies. Methods: A cross-sectional survey design was used. The participants were 301 nurses and 326 elderlies (>60 years) living in Seoul. Data were collected by convenience sampling. The research instrument utilized in this study to measure perceptions and intention to report were 11 of 12 scenarios adapted by Yoo & Kim from Moon and Williams(1993). Data were analyzed with descriptive statistics, t-test, Chi-Square and Pearson's correlation. Results: The mean score of perceptions on elder abuse was 3.11 for nurses and 2.98 for elderlies. The most severely perceived type of abuse was sexual abuse, followed by physical abuse, neglect, financial abuse, and emotional abuse. Statistically significant group differences were evident in perceptions of elder abuse in six of the scenarios and in all scenarios for intention to report. Conclusions: Differences in perceptions and intention to report on elder abuse between nurses and elderlies should be considered in developing effective measures in prevention and intervention of elder abuse.
