Objective : Children with autism spectrum disorder (ASD) commonly suffer from feeding disorders. Major feeding problems include mealtime behavior problems, picky eating, and a lack of food variety can lead to nutritional problems, developmental and social limitations, and stress for the caregivers. A review of the latest literature was conducted to gain an in-depth understanding of assessment tools for feeding disorders in children with ASD. Method : This study analyzed assessments to identify feeding problems in ASD based on previous studies searched through keywords such as ASD, ASD feeding problem, and ASD feeding evaluation. Results : The ASD feeding disorder assessment was divided into direct and indirect assessments. Indirect assessment, in which caregivers measure a child's situation using questionnaires, is mainly used. The assessment of feeding disorders in children with ASD was divided into 1) mealtime behavior, 2) sensory processing, 3) food consumption, and 4) others. Conclusion : As the main feeding disorder characteristics of children with ASD are very diverse, a comprehensive evaluation is necessary but is still limited. Swallowing rehabilitation experts, such as occupational therapists, should apply comprehensive assessment tools based on a basic understanding of the feeding problems, behaviors, and sensations in ASD.

The effects of coagulants on the microorganisms when they are injected directly into the biological treatment facility for T-P removal have been easily observed from the results of past experiments. As such this study is set out to derive the effective plans for the coagulant dosage by analyzing the effects of the injected coagulant on the microbial activity during the chemical treatment for T-P removal. The research methods entailed the assessment of removal efficiency of T-P according to the coagulant dosage while changing the molar ration between Alum and influent phosphorus. At the same time Specific Oxygen Uptake Rate (SOUR) according to the coagulant dosage was measured. SOUR was used as a method for indirect assessment of the microbial activity according to the coagulant dosage. The results from the study showed that with the increase in the alum dosage, the removal efficiency T-P tended to increase. On the other hand, the increase in coagulant dosage resulted in the decrease in SOUR, which indicates the decrease in the microbial activity. Such reduction in the activity could be explained by the increase in the concentration of removal efficiency of $TBOD_5$. Based on experiment results from the study, it is determined that coagulant dosage affects the microbial activity. Moreover, the indirect assessment on the microbial activity using SOUR is considered possible.

Purpose: This study aimed to develop a model that describes factors influencing meaning in life among the middle-aged in Korea, and to verify the appropriateness of the model. Methods: The participants were 424 middle-aged residents of Daegu city, Korea. The data were collected through a structured questionnaire from October 4 to 30, 2010 and analyzed using SPSS/WIN 18.0 and LISREL 8.30. Results: Reported life satisfaction and religion had observed to have a significant direct effect on meaning in life, and coping behavior and self-esteem exhibited significant direct and indirect effect. In addition, depression, economic status, and life stress had a significant indirect effect on meaning in life. Life satisfaction was the most influential factor, and all of these variables explained 53% of the variances in meaning in life among the middle-aged. Conclusion: The findings from this study add to the body of knowledge about the factors that influence meaning in life and need further study. The variables in this study could be used as part of the assessment of the middle-aged.

A man is a component of a large system how complex it may be so that human performance which can influence on the system safety should be included in system safety assessment. Meanwhile, human performance can vary over time due to lots of factors. Among them, stress is an indirect factor that may cause human error which can result in industrial accidents. To assess stress level of human workers, not a few assessment tools have been developed. However, it can be questionable to utilize them for human performance anticipation because they were mainly developed with the viewpoint of mental health, though stress assessment can be also required in the safety aspect. Therefore, this study aimed to survey the possibility of their application with safety purpose. About 10 kinds of work stress tools were collected and analyzed with reference to assessment items, assessment and analysis methods, and follow-up measures. The results showed that most tools focused their weights on Demands, Supports, and Relationships, in sequence. However, they, except only one tool developed by the Japanese researchers, merely advised to set up counterplans in PDCA cycle or risk management activities. In consequence, application of stress assessment tools mainly developed for mental health seemed impractical for safety purpose with respect to human performance anticipation so that it was concluded that development of a new assessment tools aimed to human performance variation and accident prevention would be inevitable.

This study was conducted to assess the effects of nutrition label education in children. The students of three randomly selected sixth-grade classes at an elementary school participated, were classified into a control group, an indirect (written message to parents) education group, and a direct (teaching children) education group. Nutrition label education was conducted in the latter two groups but not in the control group. There were no significant differences between pretest and posttest scores for nutrition knowledge or in the dietary attitudes of the control group and indirect education group. Improvements in test scores for nutrition knowledge and dietary attitudes were observed only in the direct education group. There were significant positive changes in the indirect and direct education groups, such as selecting snacks (cookies) by considering the fat content. Moreover, after the lessons, the percentage of children who chose white milk (regular milk, calcium-enriched milk, and low-fat milk) significantly increased in the direct education group. This study suggests that conducting nutrition label education helps children improve their nutrition knowledge and leads to positive changes in dietary attitudes and eating behaviors. In particular, a direct nutrition education method is more effective than an indirect method such as a written message to parents. Therefore, it is suggested that systematic and constant 'nutrition label education' be performed by nutrition teachers in elementary schools to establish healthy eating habits based on choosing nutritious snacks and processed foods.

Objective: To assess the role of arterial spin-labeling (ASL) perfusion MRI in identifying cerebral perfusion changes after indirect revascularization in children with moyamoya disease. Materials and Methods: We included pre- and postoperative perfusion MRI data of 30 children with moyamoya disease (13 boys and 17 girls; mean age ± standard deviation, 6.3± 3.0 years) who underwent indirect revascularization between June 2016 and August 2017. Relative cerebral blood flow (rCBF) and qualitative perfusion scores for arterial transit time (ATT) effects were evaluated in the middle cerebral artery (MCA) territory on ASL perfusion MRI. The rCBF and relative time-to-peak (rTTP) values were also measured using dynamic susceptibility contrast (DSC) perfusion MRI. Each perfusion change on ASL and DSC perfusion MRI was analyzed using the paired t test. We analyzed the correlation between perfusion changes on ASL and DSC images using Spearman's correlation coefficient. Results: The ASL rCBF values improved at both the ganglionic and supraganglionic levels of the MCA territory after surgery (p = 0.040 and p = 0.003, respectively). The ATT perfusion scores also improved at both levels (p < 0.001 and p < 0.001, respectively). The rCBF and rTTP values on DSC MRI showed significant improvement at both levels of the MCA territory of the operated side (all p < 0.05). There was no significant correlation between the improvements in rCBF values on the two perfusion images (r = 0.195, p = 0.303); however, there was a correlation between the change in perfusion scores on ASL and rTTP on DSC MRI (r = 0.701, p < 0.001). Conclusion: Recognizing the effects of ATT on ASL perfusion MRI may help monitor cerebral perfusion changes and complement quantitative rCBF assessment using ASL perfusion MRI in patients with moyamoya disease after indirect revascularization.

This study proposes an operational method of typhoon risk assessments in Korea, using Statistical analysis and probabilistic description of typhoon at a site. Two alternative simulation and fitting methods are discussed to predict the probabilistic typhoon wind speeds by indirect methods. A Commonly used indirect method is Russell's procedure, which generates about 1,000 Simulation data for typhoon winds, statistically evaluate the base-line distribution, and then fits the results to the Weibull distribution based on probabilistic description of climatological Characteristics and Wind field model of typhoon at a site. However, an alternative procedure proposed in this Paper simulates extreme typhoon wind data of about 150~200 years and directly fits the generated data to the Weibull distribution. The computational results show that the proposed simulation method is more economical and reasonable for typhoon risk-assessment based on the indirect method. And using the proposed indirect method, the probabilistic design wind speed for transmission towers in typhoon-prone region along the South-Western coast is investigated.

Subjective voice evaluation is necessary and important to assess the voice disorders in addition to objective voice evaluation. Subjective voice evaluation is divided into examiner and examinee subjective voice assessment. The examiner assessment represents perceptual judgment to the patient's voice such as GRBAS scale, Buffalo voice profile, consensus auditory perceptual evaluation of voice (CAPE- V) and so on. The examinee assessment consists of indirect method including voice handicap index (VHI), voice outcome survey (VOS), voice symptom scale (VoiSS), voice related quality of life (V-ROQL) and direct method which is called patient's self-subjective voice rating. This review article describes a general rule, advantages and pitfalls about GRBAS scale, VHI and patient's self-subjective voice rating which are presently most representative voice assessment tools.
