  • Ankylosis of joint is defined as limited movement due to infection, trauma, or surgical procedure. A 59-year-old female with a chief complaint of limited movements during mouth opening had a positive history of trauma to her right TMJ area about 5 years ago. From that time, progressive mouth opening limitation and intermittent pain have occurred. At the time of admission the patient showed mandibular deviation to the right side during mouth opening, with a maximum opening limited to 5 mm. On plain radiographs, right condylar enlargement and joint space reduction by newly formed bony tissues were observed. CT scans showed right condylar enlargement, cortical sclerosis, and thickening of the condyle, articular fossa and articular eminence.

  • In labor-intensive enterprise, such as garment factory, assembly line is widely used as a manufacturing process for reducing costs and production time. However, for the sake of the various working capacity of worker, idle or delay may happen and influence the rear processes. If these unforeseeable delay happened continuously, it may influence the whole manufacturing process and a model, which is called limited-cycle model with multiple periods (LCMwMP), is assumed to evaluate the influence risk. In order to minimize the risk, the assignment of the workers is focused on. In this paper, we deal with an assembly line as LCMwMP model when two kinds of workers exist, whose efficiency is assumed to two different groups. We consider an optimization problem for finding an assignment of workers to the line that minimizes total expected risk, which is exchanged to expected cost by reset model of LCMwMP. First, reset model as a simple model of LCMwMP is introduced. Then, some hypotheses of the rules of the optimal worker assignment are proposed and some numerical experiments are researched assuming the processing time as Erlang distribution. Finally, the other rules on other certain conditions are discussed.

  • Repacked mobile apps constitute about 78% of all malware of Android, and it greatly affects the technical ecosystem of Android. Although many methods exist for repacked app detection, most of them suffer from performance issues. In this manuscript, a novel method using the Constant Key Point Selection and Limited Binary Pattern (CKPS: LBP) Feature extraction-based Hashing is proposed for the identification of repacked android applications through the visual similarity, which is a notable feature of repacked applications. The results from the experiment prove that the proposed method can effectively detect the apps that are similar visually even that are even under the double fold content manipulations. From the experimental analysis, it proved that the proposed CKPS: LBP method has a better efficiency of detecting 1354 similar applications from a repository of 95124 applications and also the computational time was 0.91 seconds within which a user could get the decision of whether the app repacked. The overall efficiency of the proposed algorithm is 41% greater than the average of other methods, and the time complexity is found to have been reduced by 31%. The collision probability of the Hashes was 41% better than the average value of the other state of the art methods.

  • Purpose: This is a phenomenological study to describe the experiences of nursing students on home visiting nursing service as a community nursing practice. Method: Individual interviews were conducted on subjective experiences of 17 nursing students. Data were analyzed through Colaizzi's method in which meaningful statements were extracted and these were clustered into 6 themes. Result: The nursing students started practice with anxiety and expectation at the same time. They were frightened at the clients' inferior environment and their level of loneliness. They also felt pity and experienced complicated feelings for the clients. However, the home visiting practice was a chance for them to discard prejudice on the clients. Positive experiences on visiting nursing practice reported by the nursing students included lively interactions between nurses and the clients, and variable provision of primary nursing care. However, facts such as much limited visiting time, non-professional and limited scope of practice were reported as negative experiences. They felt both worthiness of the home visit service and restricted self-capability at the same time through the practice. They also felt sorry for the clients because the home visit services were carried out during limited time period. Regardless of this, the home visit experience provided them an opportunity of self-growth. This self-growth includes increased awareness of issues for elderly, building of self-identity as a nursing student, self-reflection, and realization of the value of family. Conclusion: This study may provide data for better understanding of nursing students experiences of home visiting nursing services. However, more study on the barriers of their community health practice is needed in the future. Moreover, it is needed to establish desirable practice environment through the collaborative relationships between the university and staffs in the public health center.

  • Using the $Methionine-2-C^{14}$, the metabolism of methionine to the experimental rats on rice diet was studied comparing with that to the rats on stock diet in this paper. The National Institute of Health strain of weaning albino rats were housed into the individual cages deviding into 2 groups, the rice diet (RD) group and the stock diet (SD) group, and fed on rice diet and stock diet respectively for 10 weeks. On the day of experiment, the rats were parenterally administered. the $methionine-2-C^{14}$ solution after fasting over night. And then the rats were sacrificed by ether anesthesia by time being of one, three, six, and twelve hours each and the organs, pituitary gland, pancreas, spleen, liver, and kidney, were taken out for the determinations of radioactivities. And also the excretion of radioactivities through urine were determined by time being. The radioactivities were determined by Autoscaler SC-51 using the planchets. The results of radioactivities of urine excretion were shown at table 3 and the results of radioactivities distibutions in the organs by time being after parenteral administration of $methionine-2-C^{14}$ were shown table 4 in the original paper. According to the results, the following are summarized; 1. The growth experiment result of rats on. rice diet and stock diet were same as shown by the previous workers indicating significant growth inhibition at the rice diet group. 2. Due to the result of radioactivity excretion through urine after administration of $methionine-2-C^{14}$, it might he considered that methionine in the rice diet seems to be limited. However, it seems to be not 주 mostly limited. 3. And due to the results of radioactivity distribution in the organs by time being, the radioactivity in the liver tissue showed appearently higher readings at this methionine study compared with the results at the lysine study shown by HAW and his co-worker. This might be interpreted, though it is not clear, that liver might require methionine as a deficient amino acid at the tissue because methionine is limited at the rice diet.

  • Due to advance in multimedia applications and integrated Internet services, the optical access networks have been actively studied. In particular, Ethernet passive optical network (EPON) has received much attention due to high bandwidth provision with low cost. In EPON system, the data transmission is carried out in two directions: downstream (from OLT to ONU) and upstream (from ONU to OLT). The downstream data is broadcasted to every ONUs, while the upstream data is point-to-point transmitted between each ONU and OLT, where the uplink is shared by all ONUs in the form of TDMA. The bandwidth allocation algorithm is required to efficiently manage the bandwidth on the uplink. The limited algorithm was proposed to enhance the capability of dynamic bandwidth allocation. In this paper, we propose the adaptive limited algorithm to enhance the shortcomings of limited algorithm. The adaptive limited algorithm enhances the dynamics on bandwidth allocation, and at the same time controls the fairness on packet delay. Through the computer simulations, it is shown that the adaptive limited algorithm achieves high dynamic on bandwidth allocation, maintains a good fairness on packet delay between ONUs, and keeps the fairness on the bandwidth on the demand basis.

  • In this paper we develop an exponentialization procedure for the modelling of open FMS networks with general processing time at each station and limited buffer size. By imposing a reasonable assumption on the solution set, the nonlinear equation system for the exponentialization procedure is formulated as a variational inequality problem and the solution existence is examined. The efficient algorithm for the nonlinear equation system is developed using linearized Jacobi approximation method.

  • This paper describes the procedure of getting information about auto-tuning of PID regulator by the injection of high step input, called limited input, during a transient time of control. The key point is that system identification and control could be continuously executed. This means that the system information obtained by limited input despite of system uncertainty can be continuously applied to the PI regulator. Simulation and experiment result of brushless DC motor system having monotone increasing step response demonstrate the usefulness of proposed auto-tuning algorithm.

  • As the interest for esthetic restoration is increasing, the usage of composite resin is increasing. The usage of composite resin is not limited to anterior teeth but is spreading to posterior area using direct & indirect methods. Generally, dual or chemical cure resin cement has been used for setting composite or porcelain inlay restoration. However, chemical cure resin cement has limited working time and it's difficult to remove excess cement from the tooth and the restoration. The dual cured composite is also difficult to remove from the tooth surface.(omitted)
