  • 변동성이 심한 증권 데이터의 특성 상 데이터의 다양한 요소에서 장애 상황이 발생한다. 따라서 실시간 대용량 데이터 처리 과정에서 발생할 수 있는 다양한 서비스 장애 요인들을 식별하고, 이를 신속하게 대응하기 위한 효율적인 실시간 모니터링 시스템 구축이 필요하다. 본 연구는 국내 증권사로 송신되는 해외 선물옵션 및 주식 데이터를 이상치 탐지 알고리즘인 Isolation Forest 를 통해 데이터의 이상치를 판단하고 알림 신호를 발생시키는 시스템을 제안한다.

  • This paper attempts to explore the place of human and disability rights from the perspective of Social Welfare within the context of the UN Disability Rights Convention of 2006. The overall discussion is focused especially upon the situations of human and disability rights in the Democratic People's Republic of Korea (North Korea) as it is being challenged to drastically address the issues of human rights in general, and disability rights in particular. The UN Disability Rights Convention challenges every ratified State party to commence legal reforms, legal harmonization, and policy and program developments to implement the Convention. Both North and South Korea are not exceptions to this. Even without drawing upon the UN's the Commission of Inquiry on Human Rights in the Democratic People's Republic of Korea, the dire situation of human rights in North Korea is well documented. However, this paper does not assume South Korea's human rights are any way superior to that of North Korea. This paper spells out areas for further action common to two Koreas and to any other nations for that matter. Apart from the general discussion on disability rights, the distinctive contribution of this paper lies in the fact that it has endeavored to draw upon any latest information and data on North Korea. It relied on various sources from UN and also from North Korea itself. One can note that North Korean disability authorities are making strenuous efforts to improve human rights of persons with disabilities in their desires to seek assistance from outside. It also shows an enormous need for international cooperation in seeking financial and material supports. This paper notes the latest political development between North and South Korea in taking "phased" steps for peace and stability as a positive sign for North and South Koreans' DPOs collaboration under the banner of International Cooperation of the article 32 of the UN Disability Rights Convention. More critically, this paper points to the further need to improve the overall data bases to ensure balanced legal reforms, policy developments and sharpen the areas of international collaboration.

  • 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.

  • The aim of this study was to evaluate the effects of 40% sucrose replacement with oligosaccharides (fructo- orisomalto-) in sponge cakes. The 18 female college students were divided into two groups; fructooligosaccharide sponge cake group (FOS) and isomaltooligosaccharide sponge cake group (IMOS). In each group, the subjects received 50 g/d of sponge cake which contained about 8 g oligosaccharides for 2 weeks. The results were as follows: (1) Frequency of stool evacuation tended to increase after 1 week and significantly increased after 2 weeks in both groups. (2) Shape and color of stool did not change in FOS group but the IMOS group showed significant improvement. (3) The stool amounts per defecation were not significantly different in both groups. (4) The time of defecation decreased 50% after 1 week in FOS group and tended to decrease gradually in IMOS group. (5) Consistency of stool was significantly decreased after 1 week in both groups and continuously decreased until 2 weeks. (6) Effort for evacuation and comfort feeling after evacuation were significantly improved only in IMOS group after 2 weeks. (7) Gastrointestinal complaints concerning diarrhea, abdominal pains, nausea, flatulence, loss of appetite and weight and bloating were apparent. The symptoms such as abdominal pains, flatulence, and bloating in FOS group lasted for 2 weeks. However, the complaints appeared only during two or three days in IMOS group. In conclusion, our results suggest that isomaltooligosaccharide was more effective than fructooligosaccharide for preventing constipation because isomaltooligosaccharide worked safely in gastrointestinal lumen.

  • Nowadays the numbers of the disabled and elderly have been increasing, and the development of adaptive clothing for these people is in demand. The purpose of this study was to give ideas and solutions for the special needs clothing design. The knowledge of medical situation of the individuals with special needs has been examined and factors affecting adaptive clothing were suggested. Twenty-one web sites were investigated and the most practical, functional, fashionable adaptive clothes were suggested by items. Construction and location of openings, number and type of fastenings, and design of garments for comfort and ease of movement were carefully considered in these clothes. Better appearance through improvement of clothing will help these people to believe that they have worth in the sight of others and in their own view of themselves. Disabled and elderly can obtain the quality of life, maintain the dignity, and make the access to the world a little bit easier by solving the particular clothing problems with all these convenient as well fashionable adaptive clothing.

  • 현재 스마트폰이나 태블릿PC 등의 터치화면 상에서 사용되는 한글 입력 방식은 qwerty, 나랏글, 천지인 등 시각 정보를 기반으로 만들어진 가상 키보드들이 사용되고 있다. 이는 시각에 문제가 없는 일반인 사용자에게는 효율적인 방식이지만 시각 장애인(시력장애, 시야 결손장애)들에게는 불편한 점이 있다. 이 문제를 개선하기 위하여 터치화면 상에서 손동작을 기반으로 한 한글 입력 방식을 제안한다. 이 방식은 사용자가 직접 기준 위치를 정하여 사용하므로 시각 정보가 제한된 상황에서도 입력할 수 있다. 또한, 이 방식은 사용자가 쉽게 배울 수 있도록 설계되었다. 모음 입력은 사용자가 쉽게 연상 되는 동작에 할당하였고, 자음 입력은 빈도수를 고려하여 자주 사용되는 자음은 편하게 움직일 수 있는 검지와 중지의 움직임에 주로 할당하였다.

  • 기존 블록체인 기술을 활용해 새로운 비즈니스 모델을 개발 및 투자하려는 기업들의 관심이 높아지고 있으나, 낮은 확장성으로 인해 기존 블록체인 기술만으로는 시장에서 활용되기 어렵다. 블록체인의 낮은 확장성을 해결하기 위해 검증된 참여자만 참여하는 프라이빗 블록체인과 프라이빗 블록체인 고속화를 위한 관련 연구가 같이 진행되고 있다. 삼성의 넥스레저는 하이퍼레저 패브릭의 다중 버전 동시성 제어(MVCC) 충돌로 인한 낮은 TPS 문제를 해결하기 위해 Accelerator를 추가하여 고속화를 진행하였다. 하지만 모든 트랜잭션을 수집하여 처리하는 방식인 Accelerator는 중앙화로 인해 악의적인 공격 타깃이 되어 단일 장애 지점 문제가 발생할 수 있으며, 공격으로 인해 위조되거나 분실된 데이터는 검증 없이 블록체인 블록에 반영되고, 한번 반영된 데이터는 수정이 어렵다. 본 논문에서는 이와 같이 프라이빗 블록체인 고속화 상황에서 발생할 수 있는 단일 장애 지점 문제를 해결하기 위해 CMT와 사기증명 기반의 고속화 하이퍼레저 패브릭 시스템을 제안했으며, 제안한 시스템을 구축하고 성능 테스트를 통해 CMT 하이퍼레저 패브릭 시스템 성능이 99.58% 유지됨과 사기증명이 가능함을 확인하였다.

  • The purpose of this study is to explore an effective learning process by applying PBL to the subject of welfare theory for the disabled. To this end, 'Welfare Measures for the Severely Disabled in the Situation of COVID-19' was conducted as a class on the welfare of the disabled. A total of 20 students participated in the PBL class, and data were collected and analyzed through individual learning activities, group learning activities, evaluation papers, and reflection journals. The analysis results showed the effectiveness of the PBL class in the learners' problem-solving ability, self-directed learning ability, critical thinking ability, and cooperative learning ability. Based on the results of this study, a method for applying problem-focused learning (PBL) to social welfare subjects was suggested.
