This study examined the effects of a dual-task virtual reality program on the cognitive function and EEG for patients with mild cognitive impairment. A dual-task virtual reality program was performed in the experimental groups while conventional occupational therapy was carried out in the control group for 30 minutes per session, which was done five days per week for 6 weeks. The results were as follows. First, the memory of the cognitive function and balance was improved significantly in the experimental group with the dual-task virtual reality program compared to the control group with the traditional occupational therapy. Second, EEG was also increased significantly in the experimental group compared to the control group. The results of this study suggest that the dual-task virtual reality program was an effective treatment method for the elderly with mild cognitive impairment and would be a cornerstone of basic data that will be helpful to those suffering from a range of diseases.

This study conducted systematic review and meta-analysis to analyze the effectiveness of a dual-task for cognitive function in patients with MCI in Korea. A search was conducted using eight databases, and the search terms were MCI, cognition, and dual task. This study includes RCT and nonRCT published from January 2013 to July 2023. A total of 682 studies were searched, and 8 studies that fulfilled the inclusion and exclusion criteria were finally analyzed. Methodological quality was assessed with the RoB, RoBANS. The meta-analysis used CMA 4.0 ver. As a result of the analysis, the overall effect size of the dual task was medium effect size. The effect size according to the outcome variables was large for orientation and executive function, and medium effect size for global cognitive function, visuospatial function, memory, and attention. As a result of analysis according to the intervention period, the effect was greater when applied for 4 to 8 weeks, and the effect size was larger when applied for 24 to 30 sessions. This study presented clinical evidence on the effectiveness and application method of a dual-task applied to improve cognitive function in patients with MCI.

The core technologies of the current transport network are OAM and protection switching to meet the sub-50ms protection switching time via a path redundancy when a link or node failure occurs. The transport networks owned by public network operators, central/local governments, and major enterprises are individually configured and managed with service resiliency in each own protected sub-network. When such networks are cascaded, it is also important to provide a node resiliency between two protected sub-networks. However, the linear protection switching in packet transport networks, such as MPLS-TP and Carrier Ethernet, does not define a solution of dual node interconnection. Although Ethernet ring protection switching covers the dual node interconnection scheme, a large amount of duplicated data frames may be flooded when a failure occurs on an adjacent (sub) ring. In this paper, we suggest a dual node interconnection scheme with linear protection switching technology in multiple protected sub-networks. And we investigate how various protected sub-network combinations with a proposed linear or ring protection process impact the service resiliency of multiple protected sub-networks through extensive experiments on link and interconnected node failures.

The systems associated with the ESS never stop. It runs 24 hours everyday. The system must be managed to run. The ESS system should perform normally even if the power IT equipment fails or communication failure occurs. Therefore, there is a need for a system that actively addresses, manages and controls the high precision power data of the ESS, even if a variety of failures occur. I would like to propose a power management communication unit to cope with the occurrence of communication failure. This paper also includes an integrated management system that can perform micro grid site management, maintenance and monitoring for the ESS system connected with the solar power generation facility.

주의력결핍 과잉행동장애는 미국에서 약 200만 명의 어린이에게 나타나는 심각한 만성 신경행동학적 장애이다. 주의력결핍 과잉행동장애 치료의 중심은 약물요법이다. 그러나 현재 환자의 약 30%는 주의력결핍 과잉행동장애를 적응증으로 갖도록 허가된 의약품들을 사용해도 적절한 치료효과를 얻지 못하고 있는 상황이다. Modafinil은 methylphenidate나 amphetamines와 같은 각성제와는 다른 약리학적 기전으로 중추신경계를 항진시킨다. 본 연구는 modafinil의 주의력결핍 과잉행동장애 치료효과에 대한 최신 지견을 얻고자, 1990년부터 2010년 3월까지 MEDLINE에 등재된 논문을 ADHD와 Modafinil이라는 MeSH terms로 검색하여 추출한 자료 중에서 대조군이 사용된 무작위 배정 및 이중맹검 임상연구 사례만을 선별하여 임상적 유용성을 평가하였다. 현재 modafinil은 주의력결핍 과잉행동 장애 치료제로 허가된 의약품은 아니지만 최근 여러 국가에서 시행된 연구들은 modafinil이 안전하고 효과적인 주의력결핍 과잉행동장애 치료제일 수 있다는 결과를 보여주고 있다.

The purpose of this study was to explore the meaning of work between Asian Americans and white Americans living with mental illness. Employment is important for recovery of Asian Americans with mental illness. However, little is known about reasons of low participation and completion rates on recovery and employment services for Asian Americans with mental illness. Although few studies have suggested that exploring cultural difference is a key to understand these issues, no study have explored how their culture influences a viewpoint on work. Therefore, a study to explore the meaning of work and influences of culture on work is required. This study used both quantitative and qualitative methods. An Internet version of world of work survey was developed based on results of study by Millner(2015) and cognitive interview. The survey was conducted from May to August 2015 and 91 people living with mental illness completed the survey. T-test was used for analyzing qualitative data and researchers analyzed qualitative data. Asian Americans showed higher preference for employment and have more difficulty at workplace and in receiving recovery and vocational services. The findings from this study can inform the development of recovery-oriented employment for people living with mental illness from diverse ethnic groups.

In order to prevent recidivism of ex-offenders, this paper needs to provide various ways of helping out-of-pocket-survivors adapt to the local community. One of solutions is the employment link through appropriate vocational training. A recent study from the US Department of Justice found that about 60% of ex-offenders unemployed for one year after their release. In such a situation, the employment possibility of ex-offenders with disabilities may even lower, so called "Dual Barriers". The purpose of this study is to present strategies to reduce the recidivism rate and increase the employment possibility of ex-offenders with disabilities presenting the cases in in the United States through literature reviews related.

It is hard to understand the coexistence of giftedness and disorder in an individual, but the twice-exceptional is widely recognized now. Gifted autistic spectrum disorder is one of its subtypes in which giftedness exists with autistic spectrum disorder (ASD) simultaneously. Like other constructs including giftedness, the nature of gifted ASD has not been understood in a fundamental and wholistic manner. This paper suggests a cognitive mechanism of gifted ASD based on the integrated model of human abilities(Song, 2009; Song & Porath, 2005), which explains how giftedness coexists with ASD and interacts with each other, producing the characteristics of gifted individuals with ASD. According to the suggested mechanism, the excessive growth of mental spaces in the brain may cause ASD. The over-grown mental spaces result in excessively strong short-term sensory memory and better facility of processing, promoting internal cognitive activities on one hand, but relative lack of cognitive activities in the real world space results in ASD symptoms on the other hand. The cognitive structure of gifted ASD students also contributes to the presentation of giftedness in specific domains. This study suggests that gifted individuals with ASD need to be discouraged from fully engaging in domains they are interested in or the most confident of, rather to be encouraged to invest their giftedness to overcome their ASD symptoms. This study also provides new perspectives on theoretical and educational approaches for gifted ASD.

연축성 발성장애(spasmodic dysphonia)는 아직까지 그 원인을 정확히 밝혀내지 못하고 있는 만성적인 발성장애로 과거에는 경직성 발성장애(spastic dysphonia)로 불리던 질환이다. 연축성 발성장애는 두 종류 즉, 내전형(adductor)과 외전형(abductor)으로 나누어지며 이중 내전형이 대부분이다. 외전형 연축성 발성장애는 발성도중에 성대가 갑자기 불수의적으로 외전되면서 음성이 중단되므로 원활히 대화하기가 힘든 질환이다. 이러한 질환은 국소적 근긴장이상(fecal dystonia)의 일종이다. 현재까지 연축성 발성장애의 치료법으로 사용되고 있는 것으로는 언어치료, botulium 독소주입술, 편측반회후두신경절 단술, 반회후두신경분쇄술, 상후두신경절단술, 갑상연골성형술, implantable stimulator 등이 있다. 연축성 발성장애 환자에 $Botox^{circledR}$ 주입에 관한 보고는 주로 내전형에 대해서만 보고되고 있으며 외전형에 대하여 보고된 예는 매우 적다.
