In this paper, we propose an algorithm for memory optimization to apply deep learning to PC. The proposed algorithm minimizes the memory and computation processing time by reducing the amount of computation processing and data required in the conventional deep learning structure in a general PC. The algorithm proposed in this paper consists of three steps: a convolution layer configuration process using a random filter with discriminating power, a data reduction process using PCA, and a CNN structure creation using SVM. The learning process is not necessary in the convolution layer construction process using the discriminating random filter, thereby shortening the learning time of the overall deep learning. PCA reduces the amount of memory and computation throughput. The creation of the CNN structure using SVM maximizes the effect of reducing the amount of memory and computational throughput required. In order to evaluate the performance of the proposed algorithm, we experimented with Yale University's Extended Yale B face database. The results show that the algorithm proposed in this paper has a similar performance recognition rate compared with the existing CNN algorithm. And it was confirmed to be excellent. Based on the algorithm proposed in this paper, it is expected that a deep learning algorithm with many data and computation processes can be implemented in a general PC.

Background: This study was conducted in order to elucidate the effects of docetaxel on the growth of peroxiredoxin 1 (Prx1) knockdown A549 xenograft tumors and further tested the role of Prx1 as a predictor for how a patient would respond to docetaxel treatment. Methods: Effects of docetaxel on the growth of scrambled- and shPrx1-infected A549 xenograft tumors in nude mice were measured. Moreover, immunohistochemical expression of Prx1 was evaluated in paraffin-embedded tissues from 24 non-small cell lung cancer patients who had received docetaxel-cisplatin regimens as a first-line treatment. Results: Docetaxel treatment in Prx1 knockdown xenograft tumor resulted in reduced tumors growth compared with other groups. Prx1 knockdown increased the production of cleaved caspases-8 and -9 in the control itself compared to scramble tumors. Moreover, docetaxel treatment in Prx1 knockdown tissue led to an increased protein band. Phosphorylated Akt was found in Prx1 scramble tissues. Phosphorylated FOXO1 was detected in the docetaxel treatment group. On the other hand, Prx1 knockdown completely suppressed the Akt-FOXO1 axis. The median progression-free survival (PFS) of patients with low Prx1 expression was 7 months (95% confidence interval [CI], 6.0-7.7), whereas the median progression-free survival of patients with high Prx1 expression was 4 months (95% CI, 4.0-5.0). However, high Prx1 expression was not associated with decreased PFS (p=0.114). Conclusion: Our findings suggest that elevated Prx1 provides resistance to docetaxel treatment through suppression of FOXO1-induced apoptosis in A549 xenograft tumors, but may not be related with the predictive significance for response to docetaxel treatment.

This paper describes a model identification method that has been applied to a commercial 12-inch RTP (rapid thermal processing) equipment with an ultimate aim to develop a high-performance advanced controller. Seven thermocouples are attached on the wafer surface and twelve tungsten-halogen lamp groups are used to heat up the wafer. To obtain a MIMO balanced state space model, multiple SIMO (single-input multiple-output) identification with highorder ARX models have been conducted and the resulting models have been combined, transformed and reduced to a MIMO balanced state space model through a balanced truncation technique. The identification experiments were designed to minimize the wafer warpage and an output linearization block has been proposed for compensation of the nonlinearity from the radiation-dominant heat transfer. As a result from the identification at around 600, 700, and $800^{\circ}C$, respectively, it was found that $y=T(K)^2$ and the state dimension of 80-100 are most desirable. With this choice the root-mean-square value of the one-step-ahead temperature prediction error was found to be in the range of 0.125-0.135 K.
The purpose of this study was to investigate the preoperative anxiety of surgical patients and to observe the effects of an experimental nursing process on the incidence of vomiting, the number of analgesics used and the voiding ability of surgical patients within a 48 hour postoperative period and also the number of postoperative days in the hospital. This study me based on a sample of 51 patients who were scheduled for abdominal surgery. They were assigned alternately to experimental and control groups. Patients assigned to the experimental group were given nursing care by the writer, using an experimental nursing process. This is a process directed toward helping the patient obtain a suitable psychological state for surgery. This process was performed by use of the following steps: 1. The nurse approached the patient with interest and concern, and observed the patient's behavior to determine the presence of anxiety. 2. The nurse explored further to find out what was causing the anxiety and what was needed too relieve it. 3. The nurse listened carefully lo the patient. 4. The nurse gave an opportunity for expression of individuality. 5. The nurse showed friendliness and reassured the patient 6. The nurse gave instruction about deep berating, turing and coughing and gave an explanation of routine preoperative preparation which decreased the unknown and so decreased the patient's anxiety- The findings of this study are as follows: 7. The investigation of preoperative anxiety through observing and interviewing revealed patients were concerned about the following: a. Length of stay in the hospital 69.7% (31 cases) b. Condition unimproved o. worse 48.,8% (30 cases) c. Postoperative pain and discomfort .56.8% (29 cases) 2. The results of the study regarding the four hypothesis were as follows: a. Preoperative psychological care not reduce the number of analysis needed during the 48 hour period following surgery. b. Preoperative psychological care did not reduce the Postoperative incidence of vomiting c. Preoperative psychological care had no influence on voiding ability following surgery. d. Preoperative psychological care significantly reduced the number of postoperative days in tile hospital. The experimental nursing process proved to be successful in decreasing the length of postoperative hospitalization (improving rate of healing). This study has demonstrated further that the relief of anxiety (emotional distress) is part of the nurse's professional role. In order to be sure psychological care is given it is important to make a nursing care plan which .includes a plan for the psychological care needed by the patient. As this care is given it can be charted off by each nurse just as medication and treatments are checked after they are given.
Orientation data of discontinuities are of paramount importance for rock slope stability studies because they control the possibility of unstable conditions or excessive deformation. Most orientation data are collected by using linear sampling techniques, such as borehole fracture mapping and the detailed scanline method (outcrop mapping). However, these data, acquired by the above linear sampling techniques, are subjected to bias, owing to the orientation of the sampling line. Even though a weighting factor is applied to orientation data in order to reduce this bias, the bias will not be significantly reduced when certain sampling orientations are involved. That is, if the linear sampling orientation nearly parallels the discontinuity orientation, most discontinuities orientation data which are parallel to sampling line will be excluded from the survey result. This phenomenon can cause serious misinterpretation of discontinuity orientation data because critical information is omitted. In the case study, orientation data collected by using the borehole fracture mapping method (vertical scanline) were compared to those based on orientation data from the detailed scanline method (horizontal scanline). Differences in results for the two procedures revealed a concern that a representative orientation of discontinuities was not accomplished. Equal-area, polar stereo nets were used to determine the distribution of dip angles and to compare the data distribution fur the borehole method versus those for the scanline method.

This paper proposed a mobile multicast technique to satisfy end-to-end QoS for various user requirements in mobile network environment. In order to provide seamless mobility, fast handoff technique was applied. By using L2 mobile trigger, it was possible to minimize remarkable amount of packet loss by delay occurred during handoff. To provide efficient multicast, concept of hierarchy was introduced to Xcast++, which results in a creation of HXcast++. HXcast++ optimized transfer path of multicast and reduced expensive multicast maintenance costs caused by frequent handoff. Suggestion of GMA (Group Management Agent) mechanism allows joining to group immediately without waiting IGMP Membership query during handoff. GMA mechanism will minimize the delay for group registration process and the resource usage due to delay of withdrawal process. And also use of buffering & forwarding technique minimized packet loss during generation of multicast tree. IntServ/RSVP was used to provide End-to-End QoS in local domain and DiffServ was used in global domain. To minimize reestablishment of RSVP session delay, extended HXcast++ control messages ware designed to require PATH message. HXcast++ proposed in this thesis is defined as multicast technique to provide end-to-end QoS and also to satisfy various user requirements in mobile network environment.

Dental fear is one of the main barriers to the use of dental services, leading patients to avoid periodical dental check-ups or treatments, thus making oral health worse, and sometimes becoming the reason that dental professionals fail control the behavior of patients. Therefore, a dental fear must be controlled carefully in order to promote oral health and effective dental treatment. This study was taken from 313 people 13 to 18 year olds to measure their levels of dental fear. After analyzing the characteristics of dental fear and its related factors, as well as other factors which influence dental fear, we acquired the following results. 1. The level of dental fear was high, compared with advanced countries with relatively good oral health. 2. The strongest physiological response experienced during a dental treatment was the tension of muscles. These dental fears were mainly related to anesthetic needles and drills. 3. Levels of dental fear became higher, the number of times for the dental services utilization had reduced, avoid regular dental examination and perceived oral disease symptoms increased. 4. One of the biggest influences on dental fears turns out to be direct painful experiences and beliefs about dentists.
This experiment was conducted to investigate the changes of rate of infected common scab and yield characteristics of fall potato(Solanum tuberosum L.) where green manual crops had been previously cultivated, crushed and tilled and P\ulcornerE transparent vinyl film had been mulched and tunneled to solar heating of soil from May 21. 1998 to July 28. 1998. The total yields of green manual crops which had been previousely cultivated were as followed order : pioneer 855F(64.3MT/ha), soybean(25.0MT/ha), red clover and orchardgrass. The average below-ground temperature at the depths of 5, 10 and 20cm were 54, 45 and 44$^{\circ}C$ during the mulching period, respectively The rate of infected area per potato tuber of common scab decreased by solar heating the soils with mulching after the soybean and red clover cultivation as with previous croppings. Plant height, SPAD(soil plant analysis development) reading, fresh weight of stems, and fall potato's tuber yields tended to increase by the cultivation of green manual crops and mulching of P\ulcornerE film. Fall potato's tuber yields were remarkably affected in the plot of soybean, red clover and pioneer 855F+cultivation of fall potato. T-N, K and Ca contents of fall potato(stem and tuber) also tended to increase by the cultivation of green manual crops and mulching of P\ulcornerE film. T-N, K and Ca contents of soil tended to increase after the cultivation of green manual crops and mulching of P\ulcornerE film and then reduced to contents of soil before green manual planting after potato harvesting.
Four low fat ground beef groups containing 10% fat plus 0, 5, 10 and 20% additional cooked old rice and a control ground beef containing 30% fat were prepared. Various sensory characteristics and instrumental textures were measured in order to determine the acceptability of low fat ground beef and to find out the most appropriate level of addition of cooked old rice as a fat replacer. Ground beef containg 10% fat had higher flavor and firmness scores than any other ground beef groups. Ground beef with 10% fat plus 5% cooked old rice had higher flavor, particle size, firmness and overall acceptability scores but lower juiciness and tenderness scores than ground beef with higher amount of cooked old rice (10 and 20%) and ground beef with 30% fat. Ground beef containing 10% fat plus 10 and 20% cooked old rice had higher juiciness, tenderness, particle size and overall acceptability scores but lower flavor and firmness scores than any other ground beef groups. Ground beef with 30% fat had higher flavor, juiciness, tenderness and firmness scores but lower particle size and overall acceptability scores. Conclusively, ground beef with the fat content reduced to 10% plus 5 or 10% additional cooked old rice as fat replacer still possessed the desirable sensory and instrumental texture properties.
Jeungpyun has a unique sponge-like texture and sour taste imparted by the lactic acid and alcohol that are produced by the addition of Takju(turbid rice wine) as a starter. Its consumption, however. has been decreased due to the long preparation time, the difficulties in quality control and the offensive odor derived from the Takju. The present study was carried out in order to shorten the preparation time and to improve the quality of Jeungpyun. To achieve the objectives an appropriate commercial lactic acid starter was selected and a cofermentation system with yeast was developed. A starter containing Lactococcus lactis, Lactococcus cremoris and Lactococcus diacetylactis was selected based on the acid production rate and the quality of the produced sour taste. It took 3 hr for the lactic acid fermentation of rice slurry. The optimum addition levels of the lactic acid starter and yeast were 0.45% and 0.60%, respectively. The lactic acid fermented rice slurry was mixed with the rice slurry separately fermented for 2 hr by yeast, and cofermented for another 1 hr before steaming. Jeungpyun Prepared by the developed method was superior in quality to that Prepared by conventional method using Takju. The developed method reduced the preparation time more than 50% compared with the conventional method.
