Purpose: This study examined the characteristics of preparation to perform activities of suicide prevention according to professional type. Methods: A structural survey was conducted from Dec. 10, 2012 to Jan. 4, 2013 for 355 participants working at suicide prevention institutions in S city. The data were analyzed in terms of frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 18.0. Results: Self-evaluation knowledge of characteristics was a significant distance depending on education and economic status. Participants were classified according to four groups based on professional type; public health nurse, social worker, fire officer, and administrative staff. Significant differences in experiences in suicide, the several items of self-evaluation knowledge, and the preparation to perform activities of suicide prevention were observed according to professional type (p<.05). Correlation among the experience, self-evaluation knowledge and preparation to perform activities of suicide prevention showed a positive correlation in public health nurse, social worker, and administrative staff (p<.05). In all professional types, the variable that predicted preparation to perform activities of suicide prevention was self-evaluation knowledge (p<.001). Conclusion: Tailor-made suicide prevention programs that affect changes in preparation to perform activities of suicide prevention should be developed by professional types.

Background: Tobacco use among adolescents is a major public health concern, and identifying predictors of smoking is necessary for planning prevention programs. The present study examined the relationship between refusal self efficacy, self esteem, smoking refusal skills and water pipe (hookah) smoking among Iranian male adolescents. Materials and Methods: A cross-sectional study was conducted with 380 Iranian male adolescents aged between 15-19 years selected by multistage sampling. The participants completed an anonymous, voluntary, self-report questionnaire. Variables independently associated with water pipe (WP) smoking were identified by multiple logistic regression analysis. Results: The mean age of the participants was $16.7{\pm}1.3$ years. The prevalence of WP smoking was 17.3%. Logistic regression analysis revealed that knowledge (OR=0.56; 95% CI: (0.37-0.79), attitude (OR=0.69; 95% CI: (0.52-0.89), self esteem (OR=0.67; 95% CI: (0.55-0.82), smoking refusal skills (OR=0.73; 95% CI: (0.55-0.87), and self efficacy (OR=.82; 95% CI: (0.61-0.93) were all signifcant prediting facotrs for adolescents WP smoking. Conclusions: The findings have implications for public health interventions. Indeed, self efficacy and smoking refusal skills should be considered when developing tailored measures for the prevention of WP smoking among adolescents.

Objective : A variety of approaches are needed to solve high suicide rates in Korean society. Although suicide prevention education has been provided for the public and suicide risk groups in Korea, a systematic discussion of simple, effective suicide prevention guidelines for the general public has yet to be made. Self-help guidelines for suicide prevention, which can help prevent suicide in at risk individuals, will be developed through expert questionnaires. Methods : In order to develop the draft guidelines, suicide prevention self-help phrases were gathered and compiled from homepages and publicity materials of domestic and international suicide prevention and related organizations. A panel of 16 suicide prevention experts conducted primary and secondary surveys using the Delphi method, which derives results from consensus among expert groups. The validity and appropriateness of the guidelines was analyzed using content validity ratios (CVR). Results : Of 33 candidate phrases selected for the suicide prevention guidelines, 9 showed high CVR after the secondary Delphi round. The highest level of support with total agreement was given to 'Do not be alone, stay with someone'. However, more than half of the panelists evaluated 14/27 of the primary Delphi round and 12/26 of the secondary Delphi round phrases as invalid. The researchers completed 10 self-help guidelines for suicide prevention, after eliminating 1 redundant phrase and including 2 additional phrases that showed relatively high CVR. Conclusion : We have developed 10 self-help guidelines for suicide prevention through the consensus of experts. Further studies on the effects of the guidleines relative to suicide rates are needed after widespread dissemination.

본 연구의 목적은 넘어짐 예방 운동이 여성노인의 체력, 자세, 낙상효능감에 미치는 영향을 규명하는 것이다. 연구 대상은 65세 이상의 여성노인 30명을 대상으로 하였으며, 그 중 14명은 운동집단, 16명은 비교 집단으로 하였다. 넘어짐 예방운동 프로그램은 탄성밴드를 이용한 다방향 근력 근지구력, 파워 운동, 자세 정렬 운동과 한국무용 동작을 접목한 다방향 동적균형, 협응력 운동으로 구분하였고 총 12주간, 주 2회, 각 60분으로 진행하였다. 운동 프로그램 전후의 체력, 자세, 낙상 효능감을 측정하여 비교하였다. 연구 결과 운동 집단은 악력을 제외한 근지구력, 심폐지구력, 유연성, 평형성, 협응력에서 유의하게 증가하였고, 자세는 상체 기울기를 제외한 어깨 기울기, 견갑골 기울기, 골반 기울기, 종골각 기울기, 다리길이 차이가 유의하게 감소하였다. 낙상 효능감 점수는 운동 집단에서는 증가하고 비교 집단에서 감소하였으나, 모두 통계적으로 유의하지는 않았다. 그러므로 넘어짐 예방운동은 체력 향상과 자세교정에 효과적이라는 결론을 내릴 수 있다. 그러나 악력(근력)을 증가하는 것과 상체기울기를 교정하는 운동프로그램의 보완이 필요하다.

Despite recent breakthroughs in deep learning and computer vision fields, the pixel-wise identification of tiny objects in high-resolution images with complex disturbances remains challenging. This study proposes a modified U-net for tiny crack segmentation in real-world steel-box-girder bridges. The modified U-net adopts the common U-net framework and a novel Self-Attention-Self-Adaption (SASA) neuron as the fundamental computing element. The Self-Attention module applies softmax and gate operations to obtain the attention vector. It enables the neuron to focus on the most significant receptive fields when processing large-scale feature maps. The Self-Adaption module consists of a multiplayer perceptron subnet and achieves deeper feature extraction inside a single neuron. For data augmentation, a grid-based crack random elastic deformation (CRED) algorithm is designed to enrich the diversities and irregular shapes of distributed cracks. Grid-based uniform control nodes are first set on both input images and binary labels, random offsets are then employed on these control nodes, and bilinear interpolation is performed for the rest pixels. The proposed SASA neuron and CRED algorithm are simultaneously deployed to train the modified U-net. 200 raw images with a high resolution of 4928 × 3264 are collected, 160 for training and the rest 40 for the test. 512 × 512 patches are generated from the original images by a sliding window with an overlap of 256 as inputs. Results show that the average IoU between the recognized and ground-truth cracks reaches 0.409, which is 29.8% higher than the regular U-net. A five-fold cross-validation study is performed to verify that the proposed method is robust to different training and test images. Ablation experiments further demonstrate the effectiveness of the proposed SASA neuron and CRED algorithm. Promotions of the average IoU individually utilizing the SASA and CRED module add up to the final promotion of the full model, indicating that the SASA and CRED modules contribute to the different stages of model and data in the training process.

Purpose: The purpose of this study was to analyze addiction prevention related content shown in middle school text books. Methods: Using a combination of the terms "addiction", "drug", "medicine", "personal preference", "smoking", "drinking", "sex", "misuse" or "abuse" as key words, the researchers screened the table of contents of 23 randomly selected middle school textbooks from the 2009 curriculum. Finally 13 textbooks (physical education=10, health=3) were selected for this study, and analyzed using Krippendorff's contents analysis. Results: Through indepth discussion and investigation of the relevant textbooks, content related to addiction prevention included material addiction (77.8%) and behavioral addiction (22.2%). The construction of addiction prevention in middle school textbooks included understanding addiction, rejection of peer temptation, and empowerment of self-control. Conclusion: When developing an intervention for addiction prevention that targets middle school students, education with accurate addiction information must be considered so that the students have the correct knowledge about addiction and addiction prevention. Additionally, the ability to reject peer temptation when invited to act upon related addiction behaviors should be treated seriously. The empowerment of self-control is also important, and can be promoted through strengthening self-regulation competence.

Purpose: Our research project aimed at presenting midwifery student self-assessment of performing the role of breast cancer prevention educator. Materials and Methods: Investigations were carried out in 2011 at the Medical University of Lublin in Poland, and Katolieke Hogeschool of Kortrijk in Belgium, after obtaining approval of the ethical committee of Polish Midwives Association (III/EC/2011/PMA). The project involved a total of 155 midwifery students, made up of 95 from Poland, and 60 from Belgium. Relations between opposing characteristics were tested with Chi-square ($x^2$) test for independent traits. To assess the dependence relation between the examined variables Pearson's corrected coefficient was used. Data base and statistics were carried out with computer software STATISTICA 9.0 (StatSoftPoland). Conclusions: Student knowledge on prevention against breast cancer was unsatisfactory. The students place of residence determined their self-estimation of personal knowledge of breast cancer prevention and diagnosing methods to assess the incidence of the disease, this knowledge being better with the students of Lublin. Better self-estimation in the students of Lublin of their personal knowledge on factors rising the risk of breast cancer, such as alimentation method, application of oral contraceptives and breast feeding was found than in Belgian students.
