This study, that is made by an on-the-spot survey and a library survey, is aimed at finding some problems in the recognition regarding public library users and suggesting the clue to solve the problems revealed in the way of having compared with 'Book-Room' and Public Library. Poor material was always a troublemaker in this study. Especially the part of 'Book-Room' phenomenon is wholly dependent upon a field survey, that is, interview with a 'book-room' clerks, gathering the advertising leaflets, a close observation on 'Book-Room', etc. There are little printed materials, much less precedent research theses. In the other parts of this paper, there are needed good statistical materials, but the nortion presented in the public library user statistics-for example pupil, students, housewives, old men, the generality of people, etc.- is so vague that it is insufficient and unhelpful for this study. In my judgment, with all these limitations, this article gets some results as follows : 1. 'Book-Room' is the cultural organization which is being operated by, for, of the community inhabitants and it takes on the character of movement - labor movement, cultural movement, and community movement. 2. The pioneer of the Book-Room is 'Yangso Hyupdong chohap' (which means good book- cooperative association) lasted from 1978 to the next year. 3. 'Arom'(means learning) Book-Room is the first real Book-Room at Seomyon district in Pusan established in 1987. 4. Book-Room can be classified by its character as 'Labor BookRoom' and 'Cultural Book-Room'. There are 10 Labor BookRooms and 4 Cultural Book-Rooms in Pusan. 5. Labor Book-Rooms organized themselves to 'Labor Book-Room conference'. 6. Book-Rooms have done their best to extort the needs and interests of the community inhabitants, but relatively public libraries do not, hence the majority of residents are neglected from the public library service. This is at Book-Rooms' back to have been spread so quickly. 7. There is a very large gap between the component ratio of community inhabitants by class and that of public library users by same criterion, that is, in the case of the former, the labor class goes beyond a half point, in the latter, the majority of public library user is composed of students and housewives. 8. Researchers and librarians have concentrated their attention and effort not upon whole residents in community but upon existing users at present time. They do not try to develope potential users. So, researchers' and librarians' recognition regarding the public library users needs to be changed. 9. The concept of 'core-user' may be the key to solve the problems related with public library users. For the purpose of ensuring the 'core-user', it is necessary to study the community and inhabitants.

Recently, a smart farm technology is drawing attention as an alternative to the decline of farm labor population problems due to the aging society. Especially, there is an increasing demand for automatic harvesting system that can be commercialized in the market. Pre-harvest crop detection is the most important issue for the harvesting robot system in a real-world environment. In this paper, we proposed a real-time tomato instance tracking algorithm by using deep learning and probability models. In general, It is hard to keep track of the same tomato instance between successive frames, because the tomato growing environment is disturbed by the change of lighting condition and a background clutter without a stochastic approach. Therefore, this work suggests that individual tomato object detection for each frame is conducted by YOLOv3 model, and the continuous instance tracking between frames is performed by Kalman filter and probability model. We have verified the performance of the proposed method, an experiment was shown a good result in real-world test data.

Using the first wave of the Korean Longitudinal Study of Ageing, this research examines the effect of elderly parent's financial structure on private income transfers from their adult children. The results show that low income elderly households are more likely to receive income transfers from their children. Generally, Korean elderly households were found to have very low liquidity in their asset structure, as the average household holds over 90% of their assets in real estate. However, it seems that the parents' potential income based on their real estate assets is unimportant in determining children's transfer decisions. Rather, the parents' labor income is found to be a key factor in children's income transfer decisions.

As a decrease in labor became a serious issue in the manufacturing industry, smart factory technology, which combines IT and the manufacturing business, began to attract attention as a solution. In this study, we have designed and implemented a real-time remote management system for smart factories, which is connected to an IoT sensor and gateway, for plastic manufacturing plants. By implementing the REST API in which an IoT sensor and smart gateway can communicate, the system enabled the data measured from the IoT sensor and equipment status data to the real-time monitoring system through the gateway. Also, a web-based management dashboard enabled remote monitoring and control of the equipment and raw material processing status. A comparative analysis experiment was conducted on the suggested system for the difference in processing speed based on equipment and measurement data number change. The experiment confirmed that saving equipment measurement data using cache mechanisim offered faster processing speed. Through the result our works can provide the basic framework to factory which need implement remote management system.

It takes lots of time and labor if a worker have to measure the water quality at a certain but designated time every day in an un-automated aqua farm. In addition, if the equipment is soaked in the sea water consistently, it will be contaminated by diverse floating matters and barnacles, and it often becomes mal-functional within 2~3 months. Therefore, we need to develop a system with which the sensed data could be checked in real time and operated automatically, while preventing the contamination of the sensor, a crucial component for water quality measuring equipment, as much as possible, and increasing the replacement cycle. We have developed a non-cleaning water quality measuring equipment and its software which are used in the fishery household of offshore aqua farms. By providing the workers with a mobile application which has a function of monitoring the water quality in real time, they can check the situation directly without going to the fishery household.

The purpose of this study was to classify the financial strategies in elderly households. The data of 4,577 households with all ages and 1255 elderly households is from the Korean Labor and Income Panel Study(2000, 2003). The data were analyzed by various statistical methods such as frequency, mean-test, Duncan's multiple range test, k-mean cluster analysis and logistic regression. Findings were as follows; First, the classified household financial strategy types were Residual(44.3%), Financial Assets(24.0%), Informal Institutional(19.7%), Diversified Portfolio(7.6%), Real Estate(4.5%). Second, the criteria of classification of the financial strategies were relative, not absolute. Third, households(both elderly households and all households) that employed a diversified portfolio strategy had the greatest net wealth.

This paper deals with the expert system for power system recognition of energized and deenergized system using circuit breaker information. The basic idea is isolating the system with the system matrix representing the system configuration and the states of the circuit breakers. The knowledge base is composed of these isolated systems and decision rules. The isolated system with the sources is recognized as the energized system and the system without the source as the deenergized system. The rules use the system matrix and the the inference scheme is simplified in a great deal. Above all, the overall searching labor of the rules is independent on the system size and it is possible to expand into the real system and the real time restoration can be carried out easily. The expert system is written in PROLOG.

본 논문은 헤겔이 말한 노동(勞動, Arbeit)의 개념이 인간 실존에 내재한 무한성 구현의 근본 기재라는 이론에 착안하여 삼계를 상생(相生)으로 소통시킨 증산(甑山)의 천지공사(天地公事)를 노동의 개념으로 해석하는 것을 목적으로 한다. 헤겔이 주체의 자유와 해방의 가능성을 노동에서 찾고 있다는 점에서 인간의 몸으로 강세한 절대자 증산이 지향한 음양합덕(陰陽合德)·신인조화(神人調化)·해원상생(解冤相生)·도통진경(道通眞境)의 사상을 근거로 하여 천지공사를 노동의 개념으로 해석하였다. 이 논문에서 주목할 점은 절대자(絶對者)에게 노동이 발생하는 사태의 의미를 파악하는 것이다. 노동은 실존계의 인간에게 발생하는 개념이다. 이념계와 자연계 사이 즉 천지 사이에 있는 인간이 무한(無限)과 유한(有限)을 이어 구체적인 산물(産物)을 만들어내는 일이 노동이다. 근대적 의미의 노동은 수동적 활동이 아닌 주체적 활동이며 주체가 자신을 무한성을 향해 확장하는 행위이다. 이러한 노동이 절대자에게 발생하는 시점으로부터 실존에 대한 무한성 구현을 향한 형이상학적 패러다임의 변혁이 시작된다. 절대자의 노동 발생의 시점이 곧 우주 변혁의 시점인 것이다. 이러한 절대자의 노동 발생은 분열에서 통합이라는 천지인(天地人) 삼계(三界)의 상생적 소통을 통한 삼계의 질적 균등성을 형성한다. 부동의 원동자로서 초월적 세계에서 현상 세계를 수직적으로 조화(造化)한 구천대원조화주신(九天大元造化主神)에게 노동이 발생하는 것은 그가 실존(實存)의 위치로 하강하여 삼계에 절대성을 전이(轉移)하여 통일(統一)하는 것으로 이어진다. 따라서 절대자로서의 상제에게 노동은 곧 실존의 자격으로 인세에 행한 직접적 소통이자 그들과의 합일(合一)이며 천지공사가 바로 절대자의 그러한 실존적 노동에 해당하는 것이다.

건설 프로젝트 내의 작업의 반복성에 주목하여 건설산업에의 학습곡선효과 적용에 관한 연구가 꾸준히 이루어졌다. 그러나 충분한 반복 작업을 가지는 초고층 프로젝트에서 학습곡선효과가 실제로 발생하는가에 대한 논란은 지속되고 있다. 이에 관해 기존의 연구들은 실제 건설 현장의 작업 생산성 데이터 분석을 통해 효과의 유무를 검증하였으나 작업 생산성의 향상 여부에만 초점을 맞추고 있을 뿐, 효과가 발생하는 과정에 관한 연구는 이루어지지 않았다. 이에 본 연구는 초고층 프로젝트에서 학습곡선효과가 발현되는 과정에 영향을 미치는 요인들을 분석하여 그 효과를 상쇄시키는 요인들을 찾고, 이를 반영한 작업 생산성 산정 모델을 제시하고자 한다. 이를 통해 기존의 이론을 보완하고 건설산업에서의 학습곡선효과 이론을 재정립하는 데 기여할 수 있다.
