Objective : This study was conducted to examine self-selected goals and the outcome measures used in the Cognitive Orientation to daily Occupational Performance (CO-OP) approach for Developmental Coordination Disorder. Methods : Studies published from January 2012 to October 2022 in the PubMed, Embase, ScienceDirect, Cochrance Library databases were searched. Keywords used for search were ('developmental coordination disorder' OR 'DCD') AND ('Cognitive Orientation to daily Occupational Performance' OR 'Cognitive Orientation to Occupational Performance' OR 'CO-OP'). Among 211 searched studies, 7 selected studies that match the thesis of this study were analyzed. Results : The selected studies showed a relatively high level of evidence overall, including two randomized experimental studies, one non-random two-group study, three non-random one-group studies, one single-subject study. The self-selected goals preference of the children was high in the order of play, education, and daily life activities. Most of applicable sessions were conducted 10 times during a 1-h period, and intervention effects showed positive outcomes on the occupation performance motor domain. To measure the effectiveness of CO-OP, the improvement of occupational performance was evaluated using Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS), and the improvement of motor skills was evaluated using Movement Assessment Battery for Children (M-ABC). Conclusion : This study is expected to be used as basic clinical data when applying the CO-OP approach to Developmental Coordination Disorder.

Although atypical sensory processing is a core feature of autism spectrum disorder (ASD), there is considerable heterogeneity among ASD individuals in the modality and symptoms of atypical sensory processing. The present study examined visual processing of children with ASD, focusing on the complexity and orientation of visual information. Age- and -IQ-matched Korean children (14 ASD and 14 typically-developing (TD) children) received an orientation discrimination task involving static spatial gratings varied in complexity (simple versus complex) and orientation (horizontal versus vertical). The results revealed that ASD children had difficulty perceiving complex information regardless of orientation, whereas TD children had more difficulty with vertical gratings than horizontal gratings. Thus, group-level differences between ASD and TD children appeared greater when gratings were presented horizontally. Unlike ASD adult literature, however, ASD children did not show superior performance on simple gratings. Our findings on typical and atypical processing of ASD children have implications for both understanding the characteristics of ASD children and developing diagnostic tools for ASD.

Objectives : The purpose of this study is to evaluate the effects of Needle-Embedding Therapy on dementia patients. Methods : We recruited 3 dementia patients who have been experiencing memory disorder and orientation disorder. The patients had been evaluated with Mini-Mental State Examination-K (MMSE-K), Global Deterioration Scale (GDS) and Clinical Dementia Rating (CDR). The patients were treated with herbal medication (Sunghyangjunggi-san) and acupuncture. After 15 days, the patients were added to Needle-Embedding Therapy. We measured MMSE-K, GDS and CDR for every 15 days. The effects of additional Needle-Embedding Therapy were compared with the effects of acupuncture and herbal medicine. Results : After Needle-Embedding Therapy was added, Patients' memory and orientation have been improved and the score of MMSE-K ascended. The grade of GDS and CDR were maintained or decreased. Conclusions : This study suggests that Needle-Embedding Therapy is significantly effective on Dementia patients.

Objective : To present effects of depression, optimism and gratitude on suicidal ideation of patients with depressive disorders. Methods : Using analyses of covariance (ANCOVA), scores on the Beck Depression Inventory (BDI), Life Orientation Test-Revised (LOT-R), and Gratitude Questionnaire (GQ-6) were compared between depressive disorder patients with higher and lower levels of suicidal ideations. A linear regression model was fitted to detect independent correlates for suicidal ideations. Results : Significantly greater level of depression and lower level of gratitude were characterized by depressive disorder patients with higher level of suicidal ideations. The fitted regression model presented that depression and gratitude were independent correlates for suicidal ideations in patients with depressive disorders. Conclusion : Our findings suggest that gratitude may be associated with lowering the level of suicidal ideation in patients with depression.

Objective : This study aimed to provide an overview of task-oriented approaches for children with developmental coordination disorder, including its definition, diagnosis, causes, and assessment, through a literature review. Subject : Eighteen international articles published between January 2000 and September 2023 were analyzed to explore the intervention strategies of Neuromotor Task Training (NTT) and Cognitive Orientation to daily Occupational Performance (CO-OP). The objectives of the interventions mentioned in the reviewed articles were categorized according to the criteria of the Occupational Therapy Practice Framework-4 (OTPF-4). The results showed that NTT more frequently set goals in the area of client factors, while CO-OP set goals only in the area of occupation. This difference in goal setting can be explained by the strategy differences between the two interventions. Conclusion : A broader and deeper understanding of strategies for interventions with task-oriented approaches to developmental coordination disorder can increase awareness of the disorder and provide a more solid basis for evidence-based practice.

Economic burden of work-related musculoskeletal disorder(WMDs) is increasing. Known causes of WMDs include improper posture, repetition, load, and temperature of workplace. Among them, improper postures play an important role. A smart sensor called SensorTag is employed to estimate the trunk postures including flexion-extension, lateral bend, and the trunk rotational speeds. Measuring gravitational acceleration vector in the smart sensor along the tri-orthogonal axes offers an orientation of the object with the smart sensor attached to. The smart sensor is light in weight and has small form factor, making it an ideal wearable sensor for body posture measurement. Measured data from the smart senor is wirelessly transferred for analysis to a smartphone which has enough computing power, data storage and internet-connectivity, removing need for additional hardware for data post-processing. Based on the estimated body postures, WMDs risks can be conviently gauged by using existing WMDs risk assesment methods such as OWAS, RULA, REBA, etc.

Magnetic properties and crystal structures of (Fe1-XCoX) Pt (X = 0, 0.2, 0.4, 0.5, 0.6, 0.8 and 1.0) ternary thin films were investigated. The order-disorder phase transformation of FePt thin films during annealing was also studied by x-ray diffraction and M ssbauer spectroscopy. The magnetic thin films were deposited on glass substrates using a dc sputtering method and were subsequently annealed at 400~$700^{\circ}C$ in a high vacuum. The as-deposited films exhibited a high degree of the <111> preferred orientation and the preferred orientation was not destroyed even after the subsequent post annealing. The coercivity of the ($Fe_xCo_{1-x}$) Pt thin films annealed at $700^{\circ}C$ showed a minimum value at the equiatomic composition of the Fe and Co atoms. The ordered structure of the FePt alloy was thought to have formed from the disordered structure by an inhomogeneous process, which was confirmed by the asymmetric peak shapes and M ssbauer spectra.

This study simulates the flexural behavior of ultra-high-performance fiber-reinforced concrete (UHPFRC) beams reinforced with steel and glass fiber-reinforced polymer (GFRP) rebars. For this, micromechanics-based modeling was first carried out on the basis of single fiber pullout models considering inclination angle. Two different tension-softening curves (TSCs) with the assumptions of 2-dimensional (2-D) and 3-dimensional (3-D) random fiber orientations were obtained from the micromechanics-based modeling, and linear elastic compressive and tensile models before the occurrence of cracks were obtained from the mechanical tests and rule of mixture. Finite element analysis incorporating smeared crack model was used due to the multiple cracking behaviors of structural UHPFRC beams, and the characteristic length of two times the element width (or two times the average crack spacing at the peak load) was suggested as a result of parametric study. Analytical results showed that the assumption of 2-D random fiber orientation is appropriate to a non-reinforced UHPFRC beam, whereas the assumption of 3-D random fiber orientation is suitable for UHPFRC beams reinforced with steel and GFRP rebars due to disorder of fiber alignment from the internal reinforcements. The micromechanics-based finite element analysis also well predicted the serviceability deflections of UHPFRC beams with GFRP rebars and hybrid reinforcements.

High school and college students majoring in dance have different types of stress because of their different circumstances and goals. The purpose of this study was to investigate the relation between multidimensional perfectionism and eating disorder in high school and college students who are majoring in dance. Questionnaires for eating disorder (Eating Disorder Inventory-2(EDI-2) made by Garner (1990) and adapted by Lee (1998)) and multidimensional perfectionism (Multidimensional Perfectionism Scale(F-MPS) made by Frost (1990) and translated by Hyun (1992) were utilized after the sentences in the questionnaires were partially revised and (rendered more appropriate for?) the purpose of this study. The questionnaires were completed by all of the subjects (n=250), but 32 of them were excluded due to insincere answers. Thus, a total of 218 questionnaires were analyzed using SPSS version 21.0. The results showed that the students with a higher education level and who were more career oriented were more likely to suffer from multidimensional perfectionism and eating disorder. In addition, multidimensional perfectionism (concern about mistakes, constant personal and parental expectation) resulted in the development and maintenance of eating disorder for the students majoring in dance. In conclusion, higher education level and greater career orientation induce greater stress in dance major students and cause them to have an incorrect physical image. Thus, these factors may cause higher psychological pressure leading to multidimensional perfectionism and eating disorder. Therefore, these students need to know how to correctly manage their body weight and how to prevent eating disorder.

This study was to know the influence of familial environment and moral development on conduct disorder. Subjects were composed of 47 male and female patients with conduct disorder(patients group), 113 general male and female students(normal group), and 173 juvenile prisoners(JP group). The Korean Form of the Family Environment Scale(FES) was used to assess the family environment of the subjects and the Korean Defining Issues Test(DIT) was used to assess the moral development. Conduct disorder was diagnosed with the DSM-III-R criteria for conduct disorder. The influence of familial environment and moral development on conduct disorder was analyzed with ANOVA and the differences among groups were verified with Scheffe test. There was no difference in the socioeconomic status and the physical abuse by the parents among the three groups. But the rates of divorce or separation of the parents were significantly highest in the JP group and higher in the patients group than in the normal group. Especially the subjects of the JP group experienced the divorce or separation of their parents during the preschool or the elementary school periods. In regard to the family environment, there was no difference among the three groups in the Subscales of Expressiveness, Independence, Intellectual-cultural orientation, Moral-religious emphasis, Organization, and Control. ‘Cohesion Subscale’ was significantly higher in the normal group than in the JP group. ‘Conflict Subscale’ was significantly higher in the JP and patients groups than in the normal group. ‘Achievement orientation Subscale’ was significantly lower in the JP group than in the patients and normal groups. ‘Activerecreational orientation’ was significantly lower in the normal group than in the JP and patients groups. In gegard to the moral developmental stage, the lower moral developmental step was higher in the JP and patients groups than in the normal group. The higher steps were significantly higher in the normal group than in the JP group. There was no significant correlation between the degree of ‘Moral-religious emphasis Subscale’ and the moral development. The clinical implication and limitation of present study were listed and discussed.
