The use of ultrasonography has recently been increasing in musculoskeletal diagnosis or intervention treatment. Ultrasound guided procedure offers a reliable alternative to fluoroscopy or computed tomography for lumbar medial branch block, facet joint block and peripheral nerves of lower extremity. Further, there is no exposure to radiation and additional equipment necessary for the protection against radiation is required. And ultrasound guided procedure needs smaller space than fluoroscopy guided procedure with real time images in the outpatient department. This article reviews ultrasound guided procedure at lumbar vertebra and peripheral nerves of lower extremity.

Applying Reinforcement Learning in everyday applications and varied environments has proved the potential of the of the field and revealed pitfalls along the way. In robotics, a learning agent takes over gradually the control of a robot by abstracting the navigation model of the robot with its inputs and outputs, thus reducing the human intervention. The challenge for the agent is how to implement a feedback function that facilitates the learning process of an MDP problem in an environment while reducing the time of convergence for the method. In this paper we will implement a reward shaping system avoiding sparse rewards which gives fewer data for the learning agent in a ROS environment. Reward shaping prioritizes behaviours that brings the robot closer to the goal by giving intermediate rewards and helps the algorithm converge quickly. We will use a pseudocode implementation as an illustration of the method.

Despite considerable commitment to the application of action learning as an organization development intervention, no identified systematic investigation of action learning practices has been reported. Based on a systematic literature review, the purpose of this paper is to identify whether researchers strike a balance between action and learning in their studies of action learning. Research findings in this study included: (1) only 32 empirical studies were found from the electronic database search; (2) based on the hypothesized continuum of Revans' original proposition of balancing action and learning, the author categorized 32 studies into three groups: action-oriented, learning-oriented, and balanced action learning; (3) there were only nine studies on balanced action learning among 32 empirical studies, whose insights included an effective use of project teams, applications of action learning for organization development, and key success factors such as time, reflection, and management support; (4) case study was among the most frequently used research method and only six quality studies met key methodological traits; and (5) therefore, more rigorous empirical research employing quantitative methods as well as case studies is needed to determine whether researchers strike a balance between action and learning in studies on action learning.

The purpose of this study was to compare the anxiety, sexual attitudes, and sexual behavior according to smartphone use and contacts with obscene materials. 110 university students surveyed demographic characteristics, smartphone use, contacts with obscene materials, anxiety, sexual attitudes, and sexual behavior, and analyzed 102 questionnaires except missing and incomplete responses. The collected data were analyzed by independent t-test or chi-square test. Men were significantly more likely to have contacts with obscene materials, sexual attitudes, and sexual behavior than the women (p<.05). In type of residence, boarding room or lodging was significantly higher at time of smartphone use, anxiety, and sexual behaviors than the home (p<.05). There was no difference in variables according to religion (p>.05). There was no difference in variables according to the level of academic achievement (p>.05). Time of smartphone use over 3 hours was significantly higher for contacts of obscene materials, anxiety, and sexual attitudes and behaviors than less 3 hours (p<.05). Higher levels of time of contacts with obscene materials were significantly higher in anxiety and sexual behaviors than lower level (p<.05). The results of this study can be used as a basis for the development of intervention programs for those who are experiencing excessive smartphone use and contacts with obscene materials.

Purpose: The purpose of this study was to examine the effects of the systematic breathing exercise program on recovery of patients with pneumothorax. Methods: An nonequivalent interrupted time-series control group posttest design was used. Participants were 40 inpatients (Experimental Group; 20, Control Group; 20) at the one University Hospital in U city. The systematic breathing exercise program including education on deep breathing exercise using incentive spirometry, Range of motion (ROM) exercise in shoulder joint, walking exercise and feedback were provided to the experimental group, while the control group carried out deep breathing exercise using incentive spirometry. The duration of chest tube insertion, duration of hospitalization, and frequency of analgesics use were measured. The data were analysed by a SPSS/WIN program. Results: The duration of chest tube insertion and duration of hospitalization in the experimental group were significantly shorter than the control group. However, there is no difference of the frequency of analgesics use between the experimental group and control group. Conclusion: The result showed that the systematic breathing exercise program was effective to improve recovery of patients with pneumothorax. This program can be applied in hospitals for patients with pneumothorax as one of the nursing intervention modalities.

Purpose: Peripheral neuropathy accompanied by sensory disturbance, such as limb paralysis and hemiplegia, is mainly caused by acute disseminated encephalomyelitis (ADEM). This case study aimed to determine the effect of ankle strengthening exercises that use proprioceptive neuromuscular facilitation (PNF) on the gait, balance, ankle-control ability, and sit-to-stand ability on a patient with ADEM. Methods: A 10-year-old male with quadriplegia and ankle-control impairment participated in this 4-week training intervention. The patient, diagnosed with ADEM, was treated with ankle strengthening exercises that used PNF. Results: The patient demonstrated improvements in balance, ankle-control ability, sit-to-stand ability, and gait performance. Outcome measures (manual muscle test, modified Ashworth scale, sensory assessment, coordination assessment, Berg balance scale, 5 time sit-to-stand test, and 10 m walk test) were taken before and after the training program. Conclusion: The results of this case suggest that an ankle strengthening exercise that uses PNF can improve the gait, balance, ankle-control ability, and sit-to-stand ability in patients with ADEM. In ADEM, the initial treatment is important, and the use of ankle strengthening exercises with PNF could lead to meaningful results. However, there is limited research due to an insufficient number of cases. In the future, more patients will need to be studied.

This study aims to assess the knowledge of teachers working with students with autism spectrum disorder (ASD) regarding applied behaviour analysis (ABA). The study was concerned with teachers' knowledge of ABA, its application in the classroom, barriers to its use and desired training opportunities and/or resources to enhance teacher application of ABA strategies in the classroom. Data were collected via an online survey completed by 190 teachers with students diagnosed with ASD in British schools. The results revealed overall knowledge of ABA strategies for classrooms, with only some teachers uninformed about the broad use and some key elements, and general familiarity with skills crucial for applying ABA. Actual knowledge of ABA was found to be high. In terms of application of ABA, the majority of the teachers employed a wide range of known strategies. A number of barrier to the application of ABA were noted including a lack of knowledge and training, a lack of administrative support and a lack of time and physical resources. Theoretical knowledge is crucial for practical applications; however, practical training was found to be important to ensure intervention efficacy.

Background: This study uses the relevance index to understand the condition of regional medical service use for cardiovascular surgery and to identify the medical service use imbalance between regions. Methods: This study calculated the relevance index of 16 metropolitan cities and provinces using resident registration address data from the Ministry of Government Administration and Home Affairs and the 2010-2014 health insurance, medical care assistance, and medical benefits claims data from the Health Insurance Review and Assessment Service. We identified developments over the 5-year time period and analyzed the level of regional imbalance regarding cardiovascular surgery through the relative comparison of relevance indexes between cardiovascular and other types of surgery. Results: The relevance index was high in large cities such as Seoul, Daegu, and Gwangju, but low in regions that were geographically far from the capital area, such as the Gangwon and Jeju areas. Relevance indexes also fell as the years passed. Cardiovascular surgery has a relatively low relevance index compared to key types of surgery of other fields, such as neurosurgery and colorectal surgery. Conclusion: This study identified medical service use imbalance between regions for cardiovascular surgery. Results of this study demonstrate the need for political intervention to enhance the accessibility of necessary special treatment, such as cardiovascular surgery.

This study aims to investigate the factors that may influence mobile dependence among school-aged children (7-9 years old), a growing social issue. Understanding the causes of mobile dependence is crucial as it can significantly impact school adaptation among these children. Given that children in this age group are greatly influenced not only by their individual characteristics but also by environmental factors, particularly parental influence, this research focuses on examining the psychological state of parents (e.g., parental stress, depression), parental ambivalence towards mobile use, and parental intervention in mobile use. The study was conducted through surveys at two different points in time. The results indicate that parental stress affects parental depression, ambivalence towards mobile use, parental intervention, and ultimately the mobile dependence of school-aged children, which in turn impacts their school adaptation. Through this study, we were able to verify the mechanisms by which parental stress and psychological attitudes toward mobile use influence mobile dependence and school adaptation in school-aged children.

Object : The relationships between the TSQ(Time structure questionnaire) and Well-being were examined. Methods : TSQ and questionnaire about Well-being were executed for 223 university students from April 26th to May 7th, 2010. The questionnaire adapted the item of the TSQ and Korean WHOQOL-BREF, SWLS(Satisfaction with Life Scale), LSES(Life Satisfaction Expectancy Scale), SHS(Subjective Happiness Scale). The questionnaires were distributed directly to the participants. Relativity between the TSQ and questionnaire about Well-being were analyzed using Pearson's correlation analysis. Results : As a result of the relationship between the TSQ and questionnaire about Well-being, overall there was a positive correlation. TSQ(sense of purpose, structured routine, persistence, past orientation) and questionnaire about Well-being showed a statistically significant correlation(p<.05). Conclusion : A structured time use and well-being by investigating the relationship, we were able to see the importance of time management. Currently, clinical occupational therapy focused on performance components, in future, intervention of personal time management to help make ones live well-being.
