In orthodontic view points, there were a few attempts to describe on the mandibular rest position with roentgenocephalometric studies for the persons with malocclusion. The purpose of the present study was to evaluate and interpret the difference in each of the Angle's classification of the malocclusion. The author has selected 115 malocclusion patients of the both sexes as subjects, whose dental ages were from III A. Two lateral cephalometric head films were taken mandible at rest and with the teeth in occlusion utilizing the Broadbent-Bolton cephalometer. Their linear and angular measurements were made directly. The author obtained the following results: 1) The change in the incisal overbite was of $-2.32\~-3.36mm$, and the overjet decreased similiarly in each class of the malocclusion. 2) The range of free-way space was of $1.97\~3.56mm$, and showed prominent in the Angle's class III malocclusion. 3) In the rest position, the mandible showed backward displacement, and it was prominent in the Angle's class III malocclusion. 4) In the change of Ar-Gn, the class I and II showed more increase of distance-than the class III. 5) In the change of ${\angel}SNL_1L_1'$, the class III showed smaller angle than the class I and II. 6) There was no significant difference between the male and female in each class of the malocclusion.

The current from the feed motor of a machine tool contains substantial information about the machining state. There have been many researches that investigated the current as a measure for the cutting forces. However it has not been reported that indirect measurement of the cutting forces from the current of the feed motor at rest is possible. The cutting force normal to the machined surface influences the machined surface of the workpiece, which makes it necessary to estimate this force to control the roughness of the machined surface. But the unpredictable behavior of the current prevents applying the current to prediction of the cutting state. In this paper, empirical approach was conducted to resolve the problem. Also parametric adaptive and fuzzy logic control strategies are applied to the force regulation problem. As a result, the current is shown to be related to the accumulation of the infinitesimal rotation of the motor, and besides the unpredictable behavior of the current is shown to be caused by the relationship. Subsequently the relationship between the current and the cutting force is identified, and it is presented that control of machined surface using the current of the feed motor at rest is possible.

Purpose: The aim of study was to identify the effects of exercise on the relief of low back pain in patients on absolute bed rest after TAE. Method: A nonequivalent control group pretest-posttest design research design was used. The participants were 43 patients who had received TAE in a university hospital; patients in the experimental group (21) received both exercise therapy and general post-op nursing care and in the control group (22) only the latter. The exercise program used in this study was modified from exercise for post CABG to exercise for post TAE, which deflect the movement of thigh in which the catheter was inserted, the lumbar region of the back and pelvis. Results: First, Low back pain scores in the experimental group were lower than the control group. Second, The first dose of analgesics in the experimental group was delayed compared to the control group. Third, There was no significant difference in bleeding complications between the experimental group control groups. Conclusion: The results suggest that the exercise program used in this study is effective for relief of low back pain in patients on absolute bed rest after TAE.

This study examined the work time, work posture, and work intensity for the actual measurement step in forest road the design work that was being carried out. The measurement of the forest road was being carried by a team of three workers and a team of four workers. The examination of work time found that the measurement of 1km took about 8 hours for the four-worker team and 12 hours for the three-worker team. The examination of work intensity found that the energy metabolic rates of the three-worker team were lower than four-worker team. Because their energy consumption per minute decreased as their work time and rest time increased. Furthermore, when appropriate rest time was applied according to work time, the energy metabolic rate decreased and the work intensity became lower. The four-worker team was more advantageous from the time and cost aspects of the forest road measurement work. Furthermore, as the rest time was very low compared to the work time, more efficient forest road measurement work would be possible if the work intensity was lowered by considering the rest time when calculating the standard work time.

The objective of this study was to investigate the physical work capacity and rest allowance for Korean males and females. Eleven males and 13 females participated in the study as subjects. An ergometer exercise test and a treadmill exercise test were conducted to measure oxygen consumption rates. The PWC values of Korean males and females were 2605.62ml/min and 1853.01ml/min in the cycle ergometer test, respectively, and 2872.10ml/min and 2057.91ml/min in the treadmill test. The PWC values of Korean females were about 70% of Korean males. The PWC values of Korean females were74.36%-78.79% of western males in the treadmill test. and 88.66%-89.32% of western males in the ergometer test. The PWC values of Korean females were 81.34%-82.98% of western females in the treadmill test, and 87.11% of western femaleles in the ergometer test. And, the results of this study showed that the rest allowance should be determined separately for male and female because of the difference in physical work capacity.

Most of conventional DSS's(Digital Signage Systems) have been built based on LAMP framework. Recent researches have shown that MEAN or MERN stack framework is simpler, more flexible, faster and more suitable for web-based application than LAMP stack framework. In this paper, we propose a design and implementation of MEARN (ME(A+R)N) stack-based real-time digital signage system, MR-DSS, which supports handing real-time tasks like urgent/instant messaging, system status monitoring and so on, efficiently in addition to conventional digital signage CMS service tasks. MR-DSCMS, CMS of MR-DSS, is designed to provide most of its normal services by REST APIs and real-time services like urgent/instant messaging by Socket.IO base under MEARN stack environment. In addition to architecture description of components composing MR-DSS, design and implementation issues are clarified in more detail. Through experimental testing, it is shown that 1) MR-DSS works functionally well, 2) the networking load performance of MR-DSCMS's REST APIs is better compared to a well-known open source Xibo CMS, and 3) real-time messaging via Socket.IO works much faster than REST APIs.
