This study aims to explore the combinations of services and technologies for academic libraries to use based on librarians' perception and establish effective service strategies accordingly. The literature review facilitated an understanding of Fourth Industrial Revolution technologies impacting the libraries. We discovered how technologies are transforming library services. We analyzed the academic library services to categorize their service structure. The survey revealed the necessity of introducing technology for each service category and the appropriate automation levels of services based on the perception of librarians. The survey results identified nine prioritized combinations of academic library services and technologies. Based on the analysis, we proposed the service-technology strategies for each category. This study has significance in exploring the potential for introducing and utilizing new technologies to enhance academic library services and exploring ways to combine services and technologies based on the common opinion of librarians.

The present paper examined the stress and ADL (activities of daily living) index in relation to the characteristics of the elderly in nursing homes. For this study, questionnaires were given to 110 seniors in the N-district of Seoul, and S-myeon, Hoengseong-gun, Gangwon Province from May 1 to September 30, 2013. For data analysis, t-test, correlation analysis, and multiple regression analysis were performed using the SPSSWIN18.0 program. The analysis of actual proof was made at a significance level of 5 percent. The findings from the analyses were as follows: first, the relocation syndrome into nursing homes has a positive correlation with the stress of deficient family visits in the category of daily stresses; second, depression has a positive correlation with the stresses of deficient private time and space and deficient family visits in the category of daily stresses; third, weight control has a positive correlation only with the stress of deficient private time and space in the category of daily stresses, whereas a nutrition deficiency has positive correlation with the stress of deficient family visits in the category of daily stresses. These findings may serve as ground source data for establishing policies regarding the stresses in relation to the characteristics and ADL index of the elderly in nursing homes.

For many years, $NO_2$ has been regarded as one of the elements among indoor air pollutants of urban homes, leading to increased public concerns on this gas. For the purpose of preparing the fundamental data for the evaluation and control of health effect relevant to $NO_2$ levels, authors measured the indoor (kitchen, living room, bed room) and outdoor $NO_2$ levels categorized by the type of house(apartment, detached dwelling) and cooking fuel(L.P.G., briquette) in the winter and summer, and surveyed the variables(kitchen ventilation, family size, parental smoking) may effect the indoor $NO_2$ levels. The level of $NO_2$ was measured by Palmes tube, and this survey was carried out at 110 homes in the Pusan area from October 1984 to September 1985. The obtained results were as follows: 1) The mean indoor and outdoor $NO_2$ level in winter and summer, respectively, was $0.029{\pm}0.012$ ppm and $0.022{\pm}0.012$ ppm in the kitchen, $0.022{\pm}0.009$ ppm and $0.018{\pm}0.010$ ppm in the living room, $0.017{\pm}0.008$ ppm and $0.016{\pm}0.010$ ppm in the bed room, and $0.021{\pm}0.007$ ppm and $0.016{\pm}0.007$ ppm outdoors. 2) In the category of the type of house and cooking fuel, the highest mean indoor and outdoor $NO_2$ level in the winter was in apartments using briquettes, and in the summer. the highest level was in apartments using L.P.G. 3) In the category of the type of house, the mean indoor and outdoor $NO_2$ level in the winter and summer was higher in the apartment group compared to detached dwelling. 4) In the category of the type of cooking fuel, the mean indoor and outdoor $NO_2$ level in the winter was higher in the briquette group, and in the summer, the L.P.G. group was higher. 5) In the category of the kitchen ventilation, family size, parental smoking and asthma attack history of children, there was an insignificant difference in the indoor $NO_2$ levels.

In many areas of technology there are machines and systems controllable in up to six degrees of freedom. Helicopters and underwater vehicles, industrial robots are among the first representatives of this category. They need six degrees of freedom in order to move and orient within their workspace. An even broader and more explosively growing area is 3D computer graphics and virtual environment. In this work, functions of 3D input device are described and two types of commercial 3D input device are presented. Then, a preliminary experiment of a low cost 6 axis force/moment sensor is presented that can also be sued as a 3D input device. A low cost force/moment sensor and its application in robot teaching experiment is described. It computes the direction of 3 components of the force and 3 components of the moment applied by human holding the sensor by hand. The concept is shown by an experiment where the tool position and orientation of a robot in 3 dimensional space is controlled by the proposed sensor.

A life cycle impact assessment was applied in an industrial waste incineration plant to evaluate the direct and indirect environmental impacts based on toxicity and non-toxicity categories. The detailed life cycle inventory of material and energy inputs and emission outputs was compiled based on the realistic data collected from a local industrial waste incineration plant, and the Korean life cycle inventory and ecoinvent database. The functional unit was the treatment of 1 tonne of industrial waste by incineration and the system boundary included the incineration plant and landfilling of ash. The result on the variation of the impact by the unit processes showed that the direct impact was decreased by 79.3, 71.6, and 90.1% for the processes in a semi dry reactor, bag filter, and wet scrubber, respectively. Considering the final impact produced from stack, the toxicity categories comprised 91.7% of the total impact. Among the toxicity impact categories, the impact in the eco-toxicity category was most significant. A separate estimation of the impact due to direct and indirect emissions showed that the direct impact was 97.7% of the total impact. The steam recovered from the waste heat of the incineration plant resulted in a negative environmental burden.

From the viewpoint of applications to manufacturing, data mining is a useful method to find the meaningful knowledge or information about states of processes. But the data from manufacturing processes usually have two characteristics which are multicollinearity and imbalance distribution of data. Two characteristics are main causes which make bias to classification rules and select wrong variables as important variables. In the paper, we propose a new data mining procedure to solve the problem. First, to determine candidate variables, we propose the multiple hypothesis test. Second, to make unbiased classification rules, we propose the decision tree learning method with different weights for each category of quality variable. The experimental result with a real PDP (Plasma display panel) manufacturing data shows that the proposed procedure can make better information than other data mining procedures.

The purposes of this study are to compare data for work-related musculoskeletal disorders(WMSDs) between Korea and USA, and to investigate status of WMSDs for industrial safety managers. The first part of this study was based on statistical data annually published by Minister of Labor of Korea and Bureau of Labor Statistics of USA. The latter was performed by using questionnaire survey for industrial safety managers in two regions. The results showed that the WMSDs incidence rate was significantly lower in Korea than in USA, and that there is big difference in the distribution of occupational illness by category of illness between Korea and USA. The questionnaire survey revealed that knowledge level about WMSDs was significantly affected depending upon corresponding companies' location and size, and that the low back pain was the most prevalent illness among varying WMSDs symptoms, followed by tendonitis/tenosynovitis, carpal tunnel syndrome, and tennis elbow. Based on this study, it is recommended that the future education/training for WMSDs focus on their preventative measures, methods/tools for identifying their risk factors, and diagnostic criteria for judging suspicious symptoms for industrial accidents, and that the governmental policy for WMSDs be changed towards financial supporting for preventive facilities, establishing objective diagnostic criteria and training for WMSDs.
