Failure situations occur frequently in the industry, and the existing 2D-based manual for this purpose is not intuitive to understand and it is difficult to immediately interact with maintenance experts. In this paper, we propose a technology that enables workers to perform maintenance in real time with the help of experts without restrictions in time and place based on augmented reality when a failure situation occurs at a remote location. A local virtual human-based expert diagnoses a failure situation based on an adapted panoramic image of a remote failure situation while wearing an HMD headset, and gives instructions to a remote operator. In addition, in an augmented reality (AR) environment in a remote location, for the interaction between the operator and the expert, the HMD's microphone is used to create the expert's hand as well as verbal communication. You can use to point or draw a picture. If this technology is used, it is possible to overcome the limitations of the existing 2D-based manual, and to provide assistance in performing maintenance smoothly remotely even if an expert does not directly visit a remote location.

A need for considering effective human resources management, in addition to the social aspect of foreign workers, has been rising as the number of foreign workers increased. This study was designed to figure out effective ways to manage foreign workers. By examining an effect of acculturation and organizational fairness on the organizational commitment of foreign laborers and moderating effects of social support, this study aims to improve their commitment, sense of belonging, and loyalty to the company. The results are as follows. Acculturation and organizational fairness has a positive effect on organizational commitment. To be specific, distribution impartiality has the strongest influence on normative commitment, and interactional justice has an effect on emotional commitment and continuous commitment the most, and a partial effect on the moderating effects of social support. Therefore, to improve productivity of foreign laborers, organizational commitment of foreign workers should be reinforced and to achieve this, acculturation and organizational fairness need to be enhanced, and there should be measures to strengthen social support for them.

이 논문은 촉각 가상 환경(Haptic Virtual Environment)에서 촉각(haptic) 데이터를 촉각 데이터 특성에 맞추어 네트워크에 적응적이고 효율적으로 전송할 수 있는 전송 알고리즘을 제안한다. 촉감 상호작용 측정을 위해 네트워크 햅틱 협업 응용을 작성하였고 지연, 지터, 손실에 따른 변화를 분석하였다. 이를 바탕으로 네트워크 트래픽에 적응할 수 있는 알고리즘을 구성하였다. 손실되거나 지터의 영향을 받은 패킷에는 간단한 선형예측 방법을 사용하여 보상하여 손실과 지터로 인한 오차를 줄였다. 이는 심각한 손실이나 지터에 의해 떨림 현상이 나타나는 햅틱 장치의 문제점을 개선하게 되었다. 또한 네트워크 협업에서 지연이 발생할 때 나타나는 클라이언트들 사이의 비동시성을 해결하기 위하여 완충시간을 두었다. 지연이 큰 클라이언트는 버퍼를 사용하지 않고 실시간으로 처리하고, 지연이 적은 클라이언트는 버퍼를 사용하여 전송받은 좌표를 완충시킨 후에 처리하는 방법을 사용하여 클라이언트들 사이의 햅틱 렌더링을 동기화 하였다. 제안된 알고리즘은 다양한 네트워크 상황에서의 협업에서 개선된 결과를 보였다. 이를 바탕으로 향후 선형예측 방법을 다양하게 적용시키고 서버와 클라이언트 사이의 동기화를 구현하는 알고리즘을 작성할 것이다. 본 논문은 다양한 네트워크 상황 에서 햅틱 데이터를 전송하고 처리하는 연구의 기초자료가 될 수 있을 것이다.

The aim of this study was to investigate the conditions and strategies of interaction for the school adjustment for the early entrance students of science academy for the gifted. To know their concerns and process of school adjustment, we interviewed six early entrance gifted students of the science academy and two gifted students preparing for their early entrance with a semi-structured questions. Using the grounded theory, a paradigm model was organized and a core category was abstracted through the open, axial, and selective coding. Based on the open coding analysis, 75 concepts, 21 sub-categories, and 10 categories were derived. In the axial coding, the paradigm model was organized by the link between 10 categories derived from open coding. Through the selective coding, this study discovered the core category about early entrance student's school adjustment was overcoming difficulties by using academic, social, and emotional strategy for school adjustment. Through this, we understand the school adjustment process of the students of early entrance to science academy for the gifted.

Efficient production of antigen specific cytotoxic T cells is critical for appropriate adoptive immune response. In vitro culture and expansion of human T lymphocyte clones are very sophisticated and subtle procedure in immune cell therapy and hard to control. Therefore, many groups devoted their efforts to manipulate artificial antigen presenting cells (aAPCs) that can induce T cell activation and clonal expansion. To mimicking of natural antigen-presenting cells, aAPCs encompass basic signal molecules required for T cell activation: MHC:antigen complexes, co-stimulatory molecules and soluble immune modulating molecules. Orchestrated organization of these molecules is important for efficient T cell activation. Here, we discuss how those molecules have been incorporated in several aAPC models, but also how physical properties od aAPC are important for interaction with T cells.

The purpose of this study was to analyze an experience of sexual traffic victims and contribute for its formation of theory based on the results. A method of study was performed by using grounded theory method of Strauss and Corbin(1988). Through the results of study, one hundred and five concepts and thirty five subcategories and seventeen categories were deducted. 'destroy of mind and body' from the central phenomenon. The core category of experience of escaping from prostitution was presented by 'return of ordinary life recovered from destroy of life 'and the process of escaping from prostitution was presented in order of 'destroy of mind and body step', 'abandonment step', 'recovery of will step', 'challenge of adaption of ordianry life step'. In the study, it followed that an independent their own will of a sexually exploited women play an important role for a successful escaping from prostitution.

This study investigated the effect of student-perceived teacher's calling on student's well-being and the mediating effects of student-perceived emotional support and adaptive cognitive emotion regulation strategies. We analyzed data from 494 high school students in South Korea by using structural equation modeling. The results showed that student-perceived emotional support from the teachers mediated the relationship between student-perceived teacher's calling and adaptive cognitive emotion regulation strategies. Also, adaptive cognitive emotion regulation strategies mediated the relationship between student-perceived emotional support and student's well-being. Furthermore, student-perceived emotional support and adaptive cognitive emotion regulation strategies sequentially mediated the indirect positive relationship between student-perceived teacher's calling and student's well-being. Based on these results, implications and recommendations for future research are discussed.

육제품 제조용 starter culture에 대한 연구는 기초과학을 바탕으로 관련 미생물의 생리대사 특성은 물론 이들의 환경적응성이나 상업적인 생산공정개발에 이르기까지 상당한 발전을 거듭해 왔다. 특히, 최근에 와서 유전공학의 응용으로 starter균주의 대사능력을 조절할 수 있고 생물학적 안전성을 쉽게 검증할수 있을 뿐만 아니라 원하는 활력을 안전하게 보존할 수 있도록 하는 연구도 진행되고 있다. 미생물의 생육환경인 육의 발효과정에 대한 연구를 통하여 육제품 starter culture개발의 근간이 되는 지식을 얻게 되었으며 어떤 요인이 발효과정중 starter 균주의 대사능력과 성장에 영향을 주는지 또한 발효과정중 starter culture간의 상호작용 및 starter와 윈래 혼합육에 존재하는 균들사이에서 일어나는 상호작용에 관한연구, 나아가서는 Bacteriocine과 Bacteriophage가 육제품제조에서 어떤 의미를 갖고 있는지 등에 관한 연구도 활발히 이루어지고 있다. 특히 이런 연구결과들을 통하여 이들 starter의 실제 상업적인 이용에 있어 원료육이나 부재료, 향신료의 선정은 물론 제조 공정을 제어하여 제품의 안전성을 기대할 수 있을 뿐만아니라 하나의 starter culture로 여러 종류의 발효sausage를 제조하여도 제품마다 최상의 능력을 발휘할 수 있는 새로운 균주의 개발에도 기여할 수 있다. 스타타컬쳐에 대한 연구상황은 균주별로 다르나 유산균에 대하여 가장 많이 연구되어 있고 Micrococci에 대한 연구도 상당히 진전되어 있다. 특히할만한 점은 아시아의 발효생선이 육제품 발효에 이용되는 Staphylococcus carnosus종의 habitat로 밝혀진 것이다. 뿐만 아니라 곰팡이 균주도 실제 praxis에 적합하게 개발시킬수 있다. 따라서 앞으로 발효육제품제조에 있어 starter culture가 갖는 의미는 매우 중요하며 특히 짧은 숙성기간을 거치는 발효소시지의 제조에 있어서는 필수불가결한 공정의 한 분야로 자리잡게 될 것이다.

The development of IT increases the importance of understanding of IT-driven ecosystems. Platform business is the representative business model in the era of innovative IT-based businesses. However, it lacks the review research that entails ecosystem perspectives from traditional disciplines in which the perspective of ecosystem had been applied. Further most of platform research have focused on the comparison between ecosystems as a whole rather than exploration on complementors in the ecosystem who are selected and survive and, in turn, contributed to maintain the ecosystem to compete with other ecosystems. The current study listed highly cited papers from economics, sociological ecology, socio-technical ecology, organization studies, and marketing research which have cumulated research on ecosystems. And the three most critical features that determine the success of complementors, which are competition, relationality, and adaptability. Present study showed how the features were explained by each perspective from the different disciplines.
