본 연구는 장애인 활동보조인 구인·구직에 관련된 인력 및 채용정보를 각각 제공하고 이를 바탕으로 최적의 구인자와 구직자가 결정되어 주기적 서비스뿐만 아니라 일회성 서비스의 매칭이 원활하게 이루어질 수 있는 비대면 플랫폼을 제안하였다. 기존의 장애인 활동보조서비스 구인·구직 방식은 수요자가 활동서비스를 요청하면 제공기관 담당자가 기관소속 활동보조인을 배정하는 일방적 방향의 매칭방식으로 이루어지고 있어 구인·구직자의 선택권은 매우 취약하다고 할 수 있다. 장애인 활동보조인의 구인·구직 플랫폼은 사용자를 구분하여 장애인 또는 장애인가족(구인자)과 장애인 활동보조인(구직자) 인터페이스로 분리되어 로그인이 가능하다. 각자의 조건에 맞는 구인과 구직을 검색하여 채팅기능을 통해 실시간 양방향 의사정합 방식의 매칭이 이루어지고, 활동보조서비스가 완료되면 구인·구직자는 각자의 입장에서 서비스 후기 및 평가를 작성할 수 있는데 이는 다음 구인·구직자의 매칭 결정에 중요한 요소로 작용할 수 있다. 실시간 양방향 의사정합 방식의 매칭 플랫폼은 단기 또는 일회성 활동보조가 필요할 때 서비스를 제공받기 어려운 사각지대를 최소화하는데도 도움이 될 것이다.

최근 대학교육은 교육 패러다임의 변화와 함께 학습자 중심의 교육 모델을 강조하고 있다. 본 연구는 대학 강의평가의 개방형 응답을 토픽 모델링으로 분석하여 학생들의 다양한 의견을 탐색하고 교육의 질을 향상시키는데 목적이 있다. 이를 위해 비수도권 대학의 2017년부터 2022년까지 강의평가 결과를 바탕으로 총 45,001개의 개방형 응답을 전공과 교양으로 구분하여 단문에 최적화된 BTM(Biterm Topic Modeling) 분석을 진행하였다. 분석 결과 전공 강의는 "비대면 수업경험에 대한 태도", "질문과 토론에 대한 태도", "출석과 성적평가에 대한 태도", "실습활동 및 발표에 대한 태도", "소통과 협업에 대한 태도"로 구분되었고, 교양 강의는 "비대면 수업경험에 대한 태도", "성적 및 평가에 대한 태도", "출석 및 수업계획서에 대한 태도", "학문적 지식과 흥미에 대한 태도", "소통과 질문에 대한 태도"로 구분되었다. 학생들의 다양한 피드백을 분석한 본 연구결과를 토대로 전공과 교양 강의의 특성을 비교하고 강의개선 및 학습경험을 향상시키는데 도움이 될 수 있는 인사이트를 얻을 수 있을 것이다.

Prymnesium patelliferum was collected from Hwajinpo, South Korea in November 2002. This is the first record of P. patelliferum in Korea waters. The characteristic shape of P. patelliferum was that of a rice grain. Cells were sub spherical or elongate, and sometimes slightly compressed. The motile cells of P. patelliferum (8-10 ㎛ long, 5-6 ㎛ broad) prossessed two equal or sub equal flagella(10.5-13 ㎛) and a short non-coiling haptonema (3-5 ㎛). The cell was covered by two layers of organic scales, which were important taxonomic characteristics. Internal scales were a narrow inflexed rim on the distal face, a thickening central and radial fibrillar pattern. External scales were very similar to internal scales with relatively tall upright rims. The ridges were in quadrants with 11-12 ridges per quadrant.

A "failure point informing device" is that if a accident of short or ground occurs in electric railway it inform us of the distance to accident point. SeoulMetro, KRRI, 2ISYS have developed this device and installed in line no.4 substation Iy-Chon, Sam-Gakgi to test its performance. A line resistance will be measured to test this device in November.

There are few factors like a due date observance of the customer's order, reducing the manufacturing lead time, and minimizing the inventory investment to successfully run the manufacturing system. It is difficult for corporation and a person concerned to be offered indicators to achieve few factors mentioned above from complex manufacturing systems having much fluctuations. Simplified-DBR based on TOC(Theory of Constraints) is a management paradigm which can offer indicators to effectively face with fluctuating market's needs when market's demand is smaller than a capacity of manufacturing system. This paper is offering a core indicator and management model which is needed to successfully run the manufacturing system for corporation and a person concerned who have short experience and knowledge and newly construct Sinplified-DBR manufacturing system. Thus, this paper provides a systemic guidance in the offered model through the simulation.

In the situation where there should be a gap between the design environments of 2D drawing and 3D BIM modeling, it is unavoidable aspect to face confusion caused by parallel usage of both technologies unless the project delivery systems are entirely upgraded to 3D. Therefore, it is critical to make efforts to minimize this confusion. Meanwhile, detailed drawings have very important roles in the construction process because they do not only concretely express construction methods for a given design plan but also provide basis for quantity takeoff and construction cost estimation etc. This paper suggests a plan to standardize detailed information based on BIM standard framework in order to make BIM realize the information. In the short term, this plan provides improved environment where both BIM and CAD technologies can be applied and, in the long term, it provides bases for BIM to replace CAD technology.

The Avengers film produced by Marvel Comics shows visual effects that were impossible to produce in the past. Companies that produce film special effects were initially equipped with large personnel and equipment, but technology is gradually evolving to be feasible for smaller companies that do not have high-priced equipment and a large workforce. The development of hardware and software is becoming increasingly available to the general public as well as to experts. Equipment and software which were difficult for individuals to purchase before quickly popularized high-performance computers as the game industry developed. The development of the cloud has been the driving force behind software costs. As augmented reality (AR) performance of mobile devices improves, advanced technologies such as motion tracking and face recognition technology are no longer implemented by expensive equipment. Under these circumstances, after implementing mobile-based facial capture technology in animation projects, we have identified the pros and the cons and suggest better solutions to improve the problem.

The concrete structures possessing good structural integrity can face durability problems due to deteriorations of concrete structures under various environmental conditions. The durability problems weaken the structural integrity in the long run. Especially, the excessive use of sea sand causes serious reinforcement corrosion and carbonation in concrete structures. An accelerated test is often used to predict deterioration as a qualitative measure, but without long term exposure test results or understanding of the relationship between the accelerated test and the long term exposure test, the accelerated test result alone can not be used effectively as a quantitative measure. In this paper, a methodology is proposed to predict the long term deteriorations, based on the result of the short-term accelerated test, of concrete containing different contents of chloride ions. Then, the correlation between two results on the steel corrosion ratio and the carbonation depth is analyzed for concrete with different chloride contents.

Among accessaries, headwear is important to protect one's face and head from the sun, wind and cold. This study was performed to provide fundamental data on college female students' head shape by classifying their head shapes and by analyzing the characteristics of each head shape in order to improve the fitness of headwear. The subjects were 193 Korean college female students. The subjects were directly measured anthropometrically and indirectly analyzed photo-graphically. By direct and indirect measurement, 5 factors were extracted through factor analysis and those factors comprised 76.34% of the total variance. 3 clusters as their head shape were categorized using 5 factor scores by cluster analysis. Type 1 was characterized by long head type and having smallest head thickness and head girth. Type 2 had average size and the most round-head type. Type 3 was characterized by short head type and the largest head thickness and head girth.

This study researchs forms of Egyptian religious dress for studying formation-process of religious dress and its ornament. The study goes abreast literature and the very spot's materials also divides god's dress, priest's. Ancient an egytian worshiped mainly animals, step by step animal's humanization. So gods were expressed animal's face and human's body. Egypt god's costume is 1st, to take off upper hament and wear loin cloth on trousers 2nd only to wear short sheath skirt. 3rd to wear shout sheath skirt and to skirt and to wear loin cloth on there 4th to cover whole body and to open hand like mummy. Egype goddess' costume is largely to wear long sheath skirt up to the ankle and we can see selkit goddess's figure that wearing kalasiris after new dynesty. Priest had been a bald head and worn loin cloth and surrounded leopard's skin on there, but after the period of empire, worn a wig and worn less stoically. Also god had hung the lion's tail at symbol of the dignity and priest had put on sandals for a ceremony.
