  • This study examines the dietary life, weight control, perceived body image, self-esteem, and eating disorder of female college students residing in Korea and China. With approval by the IRB of Pusan National University, a survey was conducted in Korea and China. A total of 574 subjects participated in the survey, and they were divided into three groups: 153 Korean female college students residing in Korea (KSK), 180 Chinese female college students residing in Korea (CSK), and 241 Chinese female college students residing in China (CSC). The group of underweight subjects far exceeded the overweight and obese groups, but there was no significant difference (p<0.05). The CSC group showed the highest food intake frequency and eating habit scores, and the KSK group, the lowest (p<0.05). However, the KSK group showed the highest daily life habit score, followed by the CSK and CSC groups, in that order. All groups showed high weight control experience rates mainly for losing weight. In particular, the KSK group showed a much higher rate than the CSC and CSK groups. All groups wanted much thinner body shapes than their actual shapes, resulting in high percentages of body image dissatisfaction. The KSK group showed a higher self-esteem score than the CSC group. The average EAT-26 score was similar across the three groups, but the percentage of eating disorders was much higher in the KSK group than in the CSC and CSK groups.

  • Objectives : The current study investigated the risk of smartphone addiction among children and adolescents with or without attention-deficit hyperactivity disorder (ADHD), risk of depression, anxiety, and self-esteem using the Smartphone Addiction Scale Proneness, Kovac's Children's Depression Inventory, State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale, commonly used in clinical medicine. Methods : Ninety five students with ADHD who visited psychiatry outpatient clinics completed the questionnaire. At the same time, 592 middle and high school students living in a similar area regardless of ADHD diagnosis, completed the questionnaire as control subjects. Results : Overall, 40.0% of 95 ADHD and 12.8% of 592 control subjects were classified as the smartphone addiction proneness group, 26.3% of the ADHD subjects and 8.3% of the control group were classified as the depression group, and 32.6% of the ADHD subjects and 16.2% of the control group were classified as the anxiety group. Significant differences were observed between the two groups. Conclusion : The results of this study suggest that ADHD subjects are more prone to smartphone addiction, becoming depressed or anxious than those in the control group. From this study, we could suggest that students with ADHD are more easily affected by smartphone addiction than normal control subjects. In addition, we might understand how some psychiatric problems like depression, anxiety, and low self-esteem are related to ADHD and smartphone addiction.

  • 지금까지 자영업은 노동시장연구에서 배제되거나, 연구가 수행되더라도 자영업 결정요인을 중심으로 이루어졌다. 그러나 자영업자는 일을 하면서도 빈곤위험에 크게 노출된 집단이다. 그럼에도 자영업자의 경제적 심각성에 주목한 논문은 드물다. 이에 본 연구는 한국복지패널을 통해 자영업자의 취업빈곤실태와 취업빈곤에 영향을 미치는 요인을 분석하였다. 분석결과 첫째, 자영업자의 빈곤율이 임금근로자보다 평균 3.2배 높다. 특히, 임시일용직의 빈곤위험이 높지만, 자영자의 빈곤율도 높다. 둘째, 자영업자의 빈곤정도는 임금근로자보다 더 심각하다. 셋째, 자영업자가 취업자 가운데 차지하는 비중은 24%이지만, 빈곤층 가운데 차지하는 비율은 53%에 이른다. 취업빈곤층의 절반이 자영업자로 구성된 것을 알 수 있다. 넷째, 로지스틱 회귀분석결과, 상용직에 비해 임시일용직과 자영자의 빈곤위험이 유의하게 높게 나타났다. 임시일용직뿐 아니라, 자영자 역시 주된 정책대상으로 관심을 기울여야 함을 말해준다. 다섯째, 고졸이하 중고령층 자영업자, 그리고 서비스업에 종사하는 중고령 자영업자의 취업 빈곤율이 다른 집단보다 더 높은 것으로 나타났다. 이들에 대한 정책개입이 시급한 것으로 볼 수 있다.

  • The purpose of this study was to identify the effect of providing toothbrushing by professionals as part of oral hygiene education for the elderly. We randomly visited 12 centers in the metropolitan city and analyzed the data of 114 participants among 310 early registrants aged >65 years, who participated in the study at all 3 time points. The subjects were categorized into an experimental group (odd-numbered visits) and a control group (even-numbered visits). Oral hygiene practices were provided for both experimental and control groups, but professional toothbrushing was performed in a different manner in the experimental group. Differences in plaque index (PI) according to the subjects' general characteristics and oral health status were assessed using the t-test, and the effect of PI difference between the experimental and control groups was assessed by repeated measure two-way analysis of variance. A stepwise multiple regression analysis was used to analyze factors affecting the PI. At baseline, the mean overall PI was 61.82. In both experimental and control groups, the PI significantly reduced from the baseline (p<0.01). At 5 weeks, the experimental group showed a decrease of 27.16 points from the baseline, and the 10-week PI was similar to the 5-week PI. The control group showed a decrease of 14.87 points from the baseline, and the PI increased by 5.74 points at 10 weeks. PI-related factors were gender and self-xerostomia. The PI was lower in the female group and the group with self- xerostomia (p<0.01). It is important to select an appropriate method to educate elderly subjects on proper removal of dental plaque and to habituate correct behavior, which requires inclusion of a direct toothbrushing intervention by a specialist.

  • Purpose: The purpose of this study was to exam me the effects of aquatic exercise on pain, fatigue, body composition, physical fitness and psychological variables in women with arthritis. Method: With a quasi-experimental design, 37 women who had arthritis were assigned into an experimental group (n=19) or a control group (n=18). Aquatic exercise consisted of one hour of exercise in water, two days per week, for six weeks and a self-help process. Measures included physiologic and psychological variables before and after the exercise. Data was analyzed with the SPSS WIN using descriptive statistics, t-test, and ANCOVA. Result: The mean age of the subjects was 59 years in the experimental group and 52 years in the control group. Pretest scores in outcome variables were similar in both groups except BMI and body fat(%). After controlling for age, shoulder flexibility scores in the experimental group improved more than the control group (Rt: F=10.58, p=.003; Lt: F=5.91, p= .02; Waist: F=4.95, p= .03). Depression scores in the experimental group decreased (F=12.96, p= .001), and self efficacy and quality of life improved more than the others (F=5.07, p= .03; F=6.9l, p= .01). Conclusion: Aquatic exercise can improve waist flexibility and shows consistent findings of improved shoulder flexibility and psychological function in women with arthritis.

  • PURPOSE. The purpose of this study is to evaluate if pre-treatment with desensitizers have a negative effect on microtensile bond strength before cementing a restoration using recently introduced self-adhesive resin cement to dentin. MATERIALS AND METHODS. Thirty-five human molars' occlusal surfaces were ground to expose dentin; and were randomly grouped as (n=5); 1) Gluma-(Glutaraldehyde/HEMA) 2) Aqua-Prep F-(Fluoride), 3) Bisblock-(Oxalate), 4) Cervitec Plus-(Clorhexidine), 5) Smart protect-(Triclosan), 6) Nd:YAG laser, 7) No treatment (control). After applying the selected agent, RelyX U200 self-adhesive resin cement was used to bond composite resin blocks to dentin. All groups were subjected to thermocycling for 1000 cycles between $5-55^{\circ}C$. Each bonded specimen was sectioned to microbars ($6mm{\times}1mm{\times}1mm$) (n=20). Specimens were submitted to microtensile bond strength test at a crosshead speed of 0.5 mm/min. Kolmogorov-Smirnov, Levene's test, Kruskal-Wallis One-way Analysis of Variance, and Conover's nonparametric statistical analysis were used (P<.05). RESULTS. Gluma, Smart Protect and Nd:YAG laser treatments showed comparable microtensile bond strengths compared with the control group (P>.05). The microtensile bond strengths of Aqua-Prep F, and Cervitec Plus were similar to each other but significantly lower than the control group (P<.05). Bisblock showed the lowest microtensile bond strength among all groups (P<.001). Most groups showed adhesive failure. CONCLUSION. Within the limitation of this study, it is not recommended to use Aqua-prep F, Cervitec Plus and Bisblock on dentin when used with a self-adhesive resin cement due to the decrease they cause in bond strength. Beside, pre-treatment of dentin with Gluma, Smart protect, and Nd:YAG laser do not have a negative effect.

  • Objective: The aim of this randomized controlled clinical trial was to compare oral health-related quality of life (OHRQoL) of patients treated with conventional, active self-ligating (ASL), and passive self-ligating (PSL) brackets in different therapeutic phases. Methods: Sixty patients (mean age 18.3 years; 29 males and 31 females) requiring orthodontic treatment were randomly and equally assigned to receive conventional (Victory Series), ASL (In-Ovation R), or PSL (Damon 3MX) brackets. OHRQoL was measured with a self-administered modified 16-item Malaysian version of the Oral Health Impact Profile for immediate (soon after the visit) and late (just before the subsequent visit) assessments of the bonding and activation phases. Data were analyzed with the Kruskal-Wallis and chi-square tests. Results: The PSL and ASL groups showed more immediate and late impacts in the bonding phase, respectively; the conventional group was affected in both the assessments. The first activation phase had similar impacts in the groups. After the second activation, the conventional group showed more immediate impacts, whereas the PSL and ASL groups had more late impacts. The commonly affected domains were "physical disability," "functional limitation," "physical pain," and "psychological discomfort." No significant differences in the prevalence and severity of immediate and late impacts on OHRQoL of the patients were noted in any therapeutic phase. Conclusions: No bracket system seems to ensure superior OHRQoL. This information could be useful for explaining the therapeutic phases, especially the initial one, and selecting the optimal bracket system based on the patient's preference.

  • PURPOSE: Proprioceptive Neuromuscular Facilitation (PNF) has been shown to improve body function and activity/participation in people with functional dysfunctions. This study evaluates if active exercise using theraband in PNF pattern may induce similar benefits as exercise using manual PNF pattern performed by physiotherapists on promoting mobility, balance and fear of fall in community-dwelling elderly. METHODS: Twenty-three community-dwelling elderly with independent activities of daily living were recruited and randomly allocated into either PNF group - exercise in PNF pattern by trained physiotherapists or Theraband-PNF (T-PNF) group - exercise using theraband in PNF pattern, for an hour, twice weekly for 4 weeks. Functional outcomes such as Timed Up and Go test, Elderly Mobility Scale, Berg balance scale, functional reach and subjective measures including fear of fall (FOF) scale, bodily pain in visual analogue scale were measured pre and post-program. RESULTS: Twenty-one participants completed the program. PNF group demonstrated significant within-group improvements in all subjective measures and objective measures. Similar within-group improvements were demonstrated in all outcome measures except FOFS in T-PNF group. However, no between-group differences were found in any of the outcome measures. CONCLUSION: Comparable improvements in functional outcomes in community dwelling elderly were demonstrated in both groups. As manual PNF exercise traditionally need clinicians' contact and feedback on patient which limit the training to be carried out extensively in community setting. The current findings suggest that exercise using theraband in PNF pattern is feasible to be adopted as self-practice exercise for community-dwelling elderly to induce beneficial effects on functional outcomes.
