This study was conducted with the aim of verifying the effects of restaurant video taping and job communication drawing board production activities on cooking job skills of high school students with intellectual disabilities. The study participants consisted of three students with intellectual disabilities enrolled in the high school course of a special school, and the experimental environment consisted of a kitchen in the restaurant and a classroom in the special school. For the research design, the technique of multiple probe design across subjects according to a single subject research was used. The intervention program consisting of independent variables was applied as a linkage procedure in which study participants videotaped the kitchen's environmental facilities, tools, materials, and staff perform cooking job skills and then taped data from the classroom scene on a job communication drawing board. Cooking job skills consisting of dependent variables are defined as the performance of research participants cooking gimbap directly in the kitchen of the restaurant. As a result of the study, it was found that participants effectively acquired, maintained, and generalized cooking job skills through intervention programs.

In the midst of going through a non-face-to-face society, most of human activities narrowed down to the platform, restrictions on external activities are bringing the internal scalability of digital technology. Metaverse is virtually shifting reality and increasing the possibility of utilization in various areas. However, researches linked to the educational effects of metaverse, especially students with disabilities, are still an unknown area that lacks exploration. This paper focuses on the fact that metaverse-education is widening educational fields that meets the various needs of disabled students to realize social good and inclusive education, and communication effects such as resolving barriers to interaction are prominent. As a research method, examining literature research papers linked to AR/VR, metaverse with communication skills, interviews, articles, and columns by experts, and policy suggestions and implications for the special education was conducted. Although the limitations of research are confirmed, significant results are found on inclusive education, which provides educational maximizing effects and realizing human rights through direct immersive experience reflecting the Cone of Experience Theory. Hopefully follow-up studies on meta-edu for disabled students will be carried out in the future, and various interdisciplinary discussions are needed to carefully observe inclusive policies and benefits so that the socially vulnerable are not excluded from technologies in ICT society.

The purpose of this study is to analyze the TPACK differences between pre-service and in-service teachers in China, and determine demographic influence variables on the differences between them. The participants of this study were 567 teachers, including 335 pre-service teachers and 232 in-service teachers from Ningxia, China. The results are as follows: First, The in-service teachers in the seven areas of TPACK scored higher than those of pre-service teachers; Second, The comparison of the average difference between teacher division and gender shows that the two factors have an interactive effect on TK. This study is meaningful because it compared the TPACK differences between pre-service and in-service teachers, and found out the effect of gender interaction on the differences in China; It provides practical suggestions for improving the TPACK ability of Chinese teachers. Finally, the discussion was conducted based on the results, and a follow-up study was suggested.

It has not been long since the current form of PDA began to be used widely. The PDA, which first came out in a recognizable form in the market a decade ago, multiplying the number of users, has recently been developed in various forms. It began to make cutting-edge technology available in PDA, and to be subdivided into various forms appropriate for special purposes, which reflected the recent intense competition in the market. It included the function of mobile phone, in tandem with the original function of PDA, by which it brought about other synergy effects and corresponded with the purpose more solidly. Due to these recent changes, PDA has had a dramatically increasing number of users, as well as the wider scope of usage and practical application by introducing new technology. However, research is required in the fields of basic usage and interface. It is important to recognize that PDA is an apparatus that stores for the users contents and information suitable for them, and that responds to them in case of need. PDA therefore needs to convey what the users require more easily and speedily without errors, and to provide them with appropriate information and contents. This paper examined the extent to which the interface of PDA including the input of contents required by the user would be efficient by questionnaires. In addition, alternatives concerning a general application environment of PDA were suggested based on the result of this survey.

The future population of Korea is expected to reach the second highest level in the world by 2060 for the elderly. It is because of the rapid development of low fertility and medical technology. The burden of society for the elderly is expected to increase steadily. The elderly person firstly appears functional disorder. They have low ability in memory and in cognitive will be. Their activities are therefore limited. And economic production capacity is sharply reduced. Self-sufficiency is a difficult situation. They need help in economic and social aspects. Products for them need research and development. The elderly have a Mild Cognitive Impairment(MCI) stage with poor cognitive abilities. It is effective to combine pharmacological and non-pharmacological treatment methods for people with mild cognitive impairment. The effects of non-pharmacological treatments on music have been proven. This paper is a study on the appearance from the viewpoint of design in the development of ancillary instruments using music therapy techniques with Digital Convergence. For this study, we investigated the preference for external appearance of mild cognitive impairment. Two times surveys were conducted. As a result, the design of home care product for the hard cognitive impaired was different from that of a conventional game machine or set top box. It should be designed according to the user's special circumstances. They are memory and cognitive abilities. Products that meet physical and mental changes must be developed.

Produced by steaming mature silkworms, HongJam is a natural functional food with various health-promoting effects. The current standard HongJam production protocol involves freezing and freeze-drying steamed mature silkworms for convenient long-term storage and/or selling it to customers. However, freeze-drying HongJam requires a range of processes and costs, which have contributed to its high resale value. In this study, we found that the cost of manufacturing HongJam powder could be reduced by homogenizing steamed mature silkworms using a high-speed blender and digital homogenizer, followed by spray drying. After the homogenized HongJam solution was digested by directly adding food-graded proteases, food-graded protease-digested homogenized HongJam solution was spray-dried. Food-graded digested protease or non-digested homogenized HongJam solutions could be used to produce food for special medical use for patients with general or specific diseases. This more efficient HongJam processing protocol proposed in this study can facilitate the development of sericulture farms and related industries by reducing the production costs of HongJam and its associated products.
