This case study investigated the effects of sensory integration therapy on social behaviors and feeding of children with intellectual disabilities who lack sensory processing abilities. The study was conducted done from September to December, 2016, and an ABA(two sessions, nine sessions, two sessions/total 13 sessions) design was used among Single Subject Research Design. Nine sessions of sensory integration program were conducted for 50 minutes each, and Wilbarger's Protocol was employed 2-3 times per day. To understand children's basic development levels, observation evaluation of each area and social maturity scale were conducted in the early stage. To Understand the children's sensory processes ability, a Sensory Profile(SP) was developed, while the activities of daily living and task performance ability scale were evaluated using the Functional Independence Measure for children(WeeFIM) and Canadian Occupational Performance Measure(COPM), respectively. Search behavior and feeding, which are social behaviors of children, were evaluated through observation. The results showed that the sensory integration program improves social behaviors of children and enables them to eat. The children's feeding was stable from the 5th session after the intervention, and the search behaviors started to change from 3 weeks after the intervention and became stable after 7 weeks. These results indicate that the sensory integration program is effective in mediating difficulties that children with intellectual disabilities who lack sensory processing ability experience in daily living.

Although Gamma Knife irradiates much more radiation in a single session than conventional radiotherapy, there were only a few studies to measure absolute dose of a Gamma Knife. Especially, there is no report of application of International Atomic Energy Agency (IAEA) TRS-398 which requires to use a water phantom in radiation measurement to Gamma Knife. In this article, the authors reported results of the experiments to measure the absorbed dose to water of a Gamma Knife Model C using the IAEA TRS-398 protocol. The absorbed dose to water of a Gamma Knife model C was measured using a water phantom under conditions as close as possible to the IAEA TRS-398 protocol. The obtained results were compared with values measured using the plastic phantom provided by the Gamma Knife manufacturer. Two Capintec PR-05P mini-chambers and a PTW UNIDOS electrometer were used in measurements. The absorbed dose to water of a Gamma Knife model C inside the water phantom was 1.38% larger than that of the plastic phantom. The current protocol provided by the manufacturer has an intrinsic error stems from the fact that a plastic phantom is used instead of a water phantom. In conclusion, it is not possible to fully apply IAEA TRS-398 to measurement of absorbed dose of a Gamma Knife. Instead, it can be a practical choice to build a new protocol for Gamma Knife or to provide a conversion factor from a water phantom to the plastic phantom. The conversion factor can be obtained in one or two standard laboratories.

This study examined the effects of laughter therapy in the elderly with degenerative arthritis who had joint pain, joint dysfunction, and depression. Through a single-blind, randomized assignment, an experimental group of 26 subjects and a control group of 26 subjects were recruited among the elderly with degenerative knee arthritis, who were over 65 years of age. From January 8 to March 11 of 2019, a total of 16 laughter therapies were administered two times a week, 60 minutes per session, in eight weeks. The pain threshold (p=.012) and joint function status (p<.001), which represents the pain, joint stiffness, and physical function, and depression (p<.001), in the experimental group improved after the eight weeks laughter therapy compared to the control group. Laughter therapy is a therapeutic intervention that can be delivered through physical or intellectual activities. This therapy is a non-invasive procedure and has the advantage that nurses can practice easily with a little training. It can be used as an intervention within community and clinical settings to relieve pain and improve depression in the elderly with arthritis.

Web search behavior has evolved. People now search using many diverse information devices in various situations. To monitor these scattered and shifting search patterns, an improved way of learning and analysis are needed. Traditional web search studies relied on the server transaction logs and single query instance analysis. Since people use multiple smart devices and their searching occurs intermittently through a day, a bundled query research could look at the whole context as well as penetrating search needs. To observe and analyze bundled queries, we developed a proprietary research software set including a log catcher, query bundling tool, and bundle monitoring tool. In this system, users' daily search logs are sent to our analytic server, every night the users need to log on our bundling tool to package his/her queries, a built in web survey collects additional data, and our researcher performs deep interviews on a weekly basis. Out of 90 participants in the study, it was found that a normal user generates on average 4.75 query bundles a day, and each bundle contains 2.75 queries. Query bundles were categorized by; Query refinement vs. Topic refinement and 9 different sub-categories.

The effects of insulin and exercise on glucose uptake of skeletal muscle were investigated in soleus muscle isolated from low dose streptozotocin induced diabetic rats in vitro. Glucose uptake was assessed by measuring $^3H$-methylglucose uptake in vitro. Basal glucose uptake in diabetes was reduced by approximately one-third of the control value($5.6{\pm}0.73{\mu}Mol$/g/20min. in diabetes versus $8.4{\pm}0.77$ in control, P<0.01). There was also a significant decrease(P<0.01) in glucose uptake of diabetes at physiologic insulin concentration ($200{\mu}IU$/ml) by 40% ($6.1{\pm}1.20$ versus $10.0{\pm}0.81$). Furthermore, maximal insulin($20000{\mu}IU$/ml)-stimulated glucose uptake was 36% lower in diabetes as compared with control($7.3{\pm}1.29$ versus $11.4{\pm}1.29$, P<0.01). In contrast, exercise(1.0km/hr, treadmill running for 45min.) effect on glucose uptake was so dramatic in diabetes that glucose uptake at basal state was 8.4+1.09 and insulin stimulated-glucose uptake were $10.2{\pm}1.47$ and $11.9{\pm}1.64$, in 200 and $20000{\mu}IU$/ml added insulin, respectively. These results suggest that insulin insensitivity develops in skeletal muscle after 2 weeks of streptozotocin-induced diabetes, but these insensitivity was recovered significantly by single session of running exercise.

Objective : The purpose of this study was to investigate the effect of brain-timing training using an Interactive Metronome (IM) on the reading abilities of children with low brain-timing abilities. Methods : A single-group pretest and posttest (retrospective study) were conducted in 8 children whose timing abilities were lower than that for their age average and who were trained from 2019 to 2021. Brain-timing training was conducted 2 or 3 times per week, with 70 sessions in total and 40-50 minutes per session, depending on the developmental characteristics of the child. Changes in brain-timing ability before and after the training were measured using the IM Long-Form Assessment (LFA), and reading ability was measured using the Basic Academic Skills Assessment:Reading (BASA:R). Results : On the basis of the results of the brain-timing ability evaluation using the LFA, the reaction times of all the children during motor tasks were decreased, resulting in statistically significant improvements in their brain-timing abilities (p < .05). Moreover, the raw scores in the BASA:R reading and fill-in-the-blank tests were significantly improved (p < .05). Conclusion : This study is meaningful in that it presents a clinical basis for brain-timing training to improve the reading abilities of children.

Objective : The purpose of this study was to analyze group programs for the elderly living in communities and to provide basic data for applying effective occupational therapy programs for the elderly in the community. Methods : From January 2009 to December 2019, articles on group programs for the elderly in the community were searched for in the NDSL, DBPia, Riss, and PubMed databases. Based on the inclusion and exclusion criteria, a total 16 out of the 147 identified studies were selected and analyzed. This review analyzed the characteristics of the participants, contents of the group program, session and duration of the intervention, outcome measures, and effect of the group program. Results : Single group pre-post test studies with evidence level III were most common (8, 50.0%), and five (31.3%) of the studies were conducted on the community-dwelling elderly. Across all the 16 studies, there were 10 types of group programs, and the most frequently used was an exercise group program (25.0%). According to the analysis of the group program period, sessions and time, the intervention period was most commonly 12 weeks (37.5%), with 8 sessions or 12 sessions (25.0%). The intervention time in the group program was most commonly 60 minutes (43.8%). Conclusion : This study can be used as a basis for the development of effective group programs for the elderly and patients with dementia in community-based long-term care services.

This study investigated the effects of a client-centered vocational rehabilitation program on vocational basic ability, vocational performance ability, and vocational adjustment ability to improve the job competency of adolescents with cerebral palsy. This study was conducted using a multiple intermittent baseline design between the behaviors of individual research subjects from March 19 to August 27, 2018. The subjects for this study were three adolescents with cerebral palsy who were attending special schools in B County in A Province. The intervention program was performed for 40 minutes every Monday and Wednesday, and the vocational basic ability, vocational performance ability, and vocational adjustment ability of the subjects were measured after each session based on the intervention step. As a result, the client-centered vocational rehabilitation program improved vocational basic ability, vocational performance ability, and vocational adjustment ability required by the targeted job for each subject. Therefore, the client-centered vocational rehabilitation program of this study is proposed as a vocational rehabilitation program because it has had a positive effect on job competency by improving the vocational basic ability, vocational performance ability, and vocational adjustment ability of adolescents with cerebral palsy.

Objective: To conduct a simulation study to determine whether artificial intelligence (AI)-aided mammography reading can reduce unnecessary recalls while maintaining cancer detection ability in women recalled after mammography screening. Materials and Methods: A retrospective reader study was performed by screening mammographies of 793 women (mean age ± standard deviation, 50 ± 9 years) recalled to obtain supplemental mammographic views regarding screening mammography-detected abnormalities between January 2016 and December 2019 at two screening centers. Initial screening mammography examinations were interpreted by three dedicated breast radiologists sequentially, case by case, with and without AI aid, in a single session. The area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and recall rate for breast cancer diagnosis were obtained and compared between the two reading modes. Results: Fifty-four mammograms with cancer (35 invasive cancers and 19 ductal carcinomas in situ) and 739 mammograms with benign or negative findings were included. The reader-averaged AUC improved after AI aid, from 0.79 (95% confidence interval [CI], 0.74-0.85) to 0.89 (95% CI, 0.85-0.94) (p < 0.001). The reader-averaged specificities before and after AI aid were 41.9% (95% CI, 39.3%-44.5%) and 53.9% (95% CI, 50.9%-56.9%), respectively (p < 0.001). The reader-averaged sensitivity was not statistically different between AI-unaided and AI-aided readings: 89.5% (95% CI, 83.1%-95.9%) vs. 92.6% (95% CI, 86.2%-99.0%) (p = 0.053), although the sensitivities of the least experienced radiologists before and after AI aid were 79.6% (43 of 54 [95% CI, 66.5%-89.4%]) and 90.7% (49 of 54 [95% CI, 79.7%-96.9%]), respectively (p = 0.031). With AI aid, the reader-averaged recall rate decreased by from 60.4% (95% CI, 57.8%-62.9%) to 49.5% (95% CI, 46.5%-52.4%) (p < 0.001). Conclusion: AI-aided reading reduced the number of recalls and improved the diagnostic performance in our simulation using women initially recalled for supplemental mammographic views after mammography screening.

Objectives: This study investigates the impact of M&L psychotherapy on an adolescent with anxiety disorders transitioning into adulthood, using a retrospective mixed-method approach. Methods: An adolescent with Diagnostic Statistical Manual of Mental Disorders (DSM)-5-diagnosed anxiety disorders underwent combined treatment with M&L psychotherapy and complex Korean medicine therapy over a period of approximately two years. Patient records tracked the diagnosis, treatments, and progress. In-depth interviews were also conducted. The study used a convergent parallel mixed-method approach, integrating quantitative analysis from psychological assessments, including the State-Trait Anxiety Inventory (STAI-X), the Core Seven Emotions Inventory-short form (CSEI-s), and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), with qualitative analyses of traditional Korean medicine counseling session notes, interviews, and other qualitative psychological assessments. Results: State anxiety decreased from 40 to 36, and trait anxiety decreased from 42 to 34. MMPI-2 L scale scores decreased slightly to 64T, whereas S scale scores increased to 62T, and FRS scores decreased to 70T from an initial score of 78T. Qualitative analysis revealed an increase in the MMPI-2 Es scale, identified as "subjectivity." Joy (喜) emerged as the highest emotional profile score in the CSEI-S. Scores for anger (怒), thought (思), fear (恐), and fright (驚) decreased, indicating improved negative emotions. Qualitatively, expressions of determination to "move forward" and "strengthen the mind" were noted, suggesting enhanced "lower danjeon (下丹田)." Conclusions: Integrating traditional Korean medicine treatment with M&L psychotherapy for a vulnerable adolescent with anxiety disorders demonstrated efficacy. Further research is warranted to substantiate the effectiveness of M&L psychotherapy and advocate for its wider adoption in mainstream practice.
