본교에서 강의실, 회의실 등 공용공간을 사용하기 위해서는 사용자가 수기로 양식을 작성하여 제출하고 담당자가 처리해야 한다. 이 방식은 사용자가 사용하고자 하는 공간의 예약 현황을 확인할 수 없고, 사용신청 과정에서 직접 담당자를 찾아가야 한다는 불편함이 따른다. 본 연구에서는 이러한 불편함을 개선하기 위하여 마이크로 서비스 아키텍처 기반의 공간 예약 웹서비스를 구현한다.

본 논문에서는 최근 들어 본격적인 연구개발이 활성화되고 있는 무선 데이터 통신서비스를 근간으로 한 미세정보 감시 시스템(RMIMS: radio interfaced micro information monitoring system or MICROS: micro information and communication remote object-oriented system)에 대한 QoS(quality of service, ex: packet loss)를 보장하는 새로운 움직이는 다중 기지국(multiple IS-MMBS) 서비스 방법을 제안하였다. MMBS 서비스 지역에서 실시간 트래픽 형태의 RMIMS 터미널 응용서비스가 발생하거나 서비스 지역에 배치되는 RMIMS 터미널 수의 증가 또는 높은 전송대역폭을 요구하는 RMIMS 응용서비스 등으로 인하여 하나의 IS-MMBS 만으로는 기 서비스 중인 RMIMS 터미널 및 신규RMIMS 터미널에 대한 패킷 손실 여부 같은 QoS를 만족하는 서비스가 불가능한 경우가 발생한다. 이러한 경우에 다중 IS-MMBS을 이용하여 RMIMS 터미널의 QoS를 보장하는 MMBS 서비스를 제공할 수 있다. 제안한 다중 IS-MMBS 서비스 모드는 RMIMS 클러스터링 방법과 MMBS 세그먼트(segment) 방법에 따라 터미널 분할방법(terminal segment method), 영역 분할방법(region segment method ), 응용서비스별 분할방법(application based segment method), 트래픽 타입별 분할방법(traffic type based method), 중첩 분할방법(overlapping segment method), 복합 분할방법(hybrid segment method)으로 분류 제안하였다.

The advanced technology of micro-machining is starting to penetrate our lives. This technology, with which it is possible to make micro-structures by means of processing on the order of nm (micrometer = 1/1,000 mm) or less, is realizing machines that were only part of our wildest imagination. However, the fact is that many issues remain in the quest for a variety of applications. With the advent of computing technologies, information technologies, and telecommunications technologies, we foresee the need for new approaches in design, process, and the use of materials, technologies, and people in a globalized manufacturing enterprise. A new thinking paradigm is needed to focus on quality of service on the products we design and manufacture. Factories in different regions need to be co-ordinated through use of the state-of-the-art information on productivity, diagnostics, and service evaluation of manufacturing systems could be shared among different locations and partners. In this research, We develope the internet based Diagnosis system for micro machining and evaluate its characteristics by using mechatronic sensor like Dynamometer, acoustic emission, Acceleration sensor, micro phone, vision, infra-red thermometer.

As the DT of micro businesses emerges as an important task, the government is also promoting support projects such as policy establishment and micro business education. This study aims to develop a new index (checklist) that can objectively measure the level of digital literacy required for DT in the tertiary industry, which accounts for the largest share of micro business owners. In this study, indicators were derived through review of existing studies and FGI, and the validity and reliability of Likert 5 were measured for decision makers in the tertiary industry. In the field of digital literacy for micro business owners, a total of 22 indicators were developed, largely composed of basic technology environment competency, information utilization competency, information dissemination and production capability, and mind recognition capability. This study has academic significance in that it can contribute to accurately understanding the digital capabilities of micro business owners by developing a digital literacy index for micro business owners, a specific group lacking in research.

There are continuos tendencies toward that foreign tourists increase. Since 55% of them visit Korea without data communication for saving the communication costs, they can not utilize a variety of O2O services through QR/NFC/Beacon. There have been some researches to provide a smart map service based on the micro webpage technology even without data communication. But, they do not suggest how the templates are retrieved into their smart-phones. In this paper, we describe a mobile tourist information system for those who have no data communication. We utilize the micro webpage technology to develop a system for market promotion, shopping goods, and tourist maps. What matters in the micro webpage techniques is that the templates should be already downloaded to the users' smart phones before using it. The preceeded research did not mention the problem. We suggest a scheme that tourists obtain the tremplates in the information offices on the spot through Wi-Fi. We describe the details of the system, and evaluate the data overhead of templates and the time to be downloaded. We show that the overheads are endurable, which means that the system would be working well.

Objectives: This study was conducted to identify the job characteristics and health status of sales and service workers at micro-enterprises. Methods: Multivariate analyses were conducted using data on respondents to the 5th Korean Working Conditions Survey who were business owners (7,572 persons) or employees (3,317) working in sales or service positions at micro-enterprises. Results: Among those analyzed, business owners were found to experience worse health conditions than employees. Business owners also differed from workers in terms of job characteristics. More than employees, they engaged in tiring or painful postures that negatively affected subjective health condition, experience of muscle pain, and experience of depression or anxiety. While employees' health was negatively affected by dealing with angry customers, the health status of business owners was negatively affected even by dealing with ordinary customers. Conclusions: These results show that the owners of micro-enterprises were in a more vulnerable state of health rather than their employees. In order to address this, it is necessary to correct work posture and reduce the stresses that come from customers.

Semi-micro-HPLC using a column-switching technique was developed for simultaneous determination of vitamin A and E contents in infant formula. Vitamin A and E were extracted by PDA - HPLC with reversed phase column using organic solvent and their contents in Certified Reference Material (CRM) and infant formula were determined and compared with hydrolysis method and rapid extraction. Developed method has many advantages of simple and rapid sample preparation and simultaneous determination of vitamin A and E by micro-HPLC using reversed phase column.

Recently Micro-blog service is used quickly in our life with dissemination of Smart-phone. This study performed based on a view that there is a difference of user's intention to reuse Web-blogs & Micro-blogs. This study also based on the existing motive theory for using which considers five factors-information, entertainment, interaction, personalization, and convenience. The AMOS structure equation used for the analysis of users' revisit intention. The results of the study shows that Micro-blogs are influenced by entertainment, personalization, and convenience. On the other hand, Web-blogs are influenced by entertainment, and personalization.

Background: We measured the weight characteristics, intercellular space volume as a proportion of root volume, and quantities of the functional component in Angelica gigas Nakai, collected from four cultivation areas in Pyeongchang, including Tapdong-ri and SangjinBu-ri, and tested the results for correlations. Methods and Results: Dry weight was the highest in the Tapdong-ri group ($13.37{\pm}0.13g$) and the lowest in the SangjinBu-ri group ($11.90{\pm}0.57g$). The percentage of intercellular spaces within the roots, determined by micro-CT camera, was the highest in the Tapdong-ri group ($6.44{\pm}0.76%$) and the lowest in the SangjinBu-ri group ($9.01{\pm}2.15%$). The quantity of functional components were the highest in the Tapdong-ri group ($116.13{\pm}9.53mg/g$) and the lowest in the SangjinBu-ri group ($99.77{\pm}23.23mg/g$). Conclusions: The dry weight of A. gigas significantly correlated with the volume and percentage of intercellular space. An increase in the dry weight resulted in a negative correlation between the volume and ratio of the intercellular spaces. The volume of intercellular space correlated negatively with levels of the functional components, this was significant in the case of the nodakenin, decursin and decursinol angelate content (p < 0.016).
