Although shoes industry in Korea is superior in global competition in terms of material, parts, and developmental ability, it has declined due to the lack of design in consideration of OEM production and marketing ability. Shoes industry in Korea has aimed at making inroad to North American market centered with the United States, but it has not focused on Europe market that much. However, as Europe transformed into EU, which is a large economic community, European market is being considered as a great potential for Korean shoes industry, which we can never neglect of. So far, there have been researches of marketing strategic methods to make inroad to the United States and South-East Asian markets, but there has been almost no marketing approach to European shoes market. Therefore, in this study I prepare strategic marketing plans for Korean shoes enterprises to make inroads to European markets, so that they can enter the market successfully, and this is the purpose of this study. In case that Korean shoes industry makes inroads to European market, there are important terms to examine. The strategic terms for consideration to examine are as follows. First, shoes companies such as Nike and Adidas are aware of India. Turkey, and Rumania as new footholds for production, as they have accounted continuous wage claim and labor dispute. Especially Turkey and Rumania are expected to have much competitive strength in price, as they are expected countries for joining EU. Second, we need to shift our understanding of the importance of design for European shoes market. We should pay close attention to the fact that the role of leading companies is to design. Third, Germany, England, and Italy have global-level of specialize institutions and organizations for shoes education and have been succeeded in knowledge industrialization. Fourth, we should consider that the concepts for shoes are changing from innovation in production to in products. Fifth, we should develop specialized concept centered in individualized categories. Sixth, we should open up new markets actively by connecting large shopping centers and multi-shops. Seventh, we should look for the opportunities to expand market through the utilization of BIFOS. Lastly, we should expand our support for opening up markets and participating fairs in foreign countries.

The data retention characteristics depending on neighbor cell's threshold voltage (Vt) in a multilevel NAND flash memory is studied. It is found that a Vt shift (${\Delta}Vt$) of the noted cell during a thermal retention test is increased as the number of erase-state (lowest Vt state) cells surrounding the noted cell increases. It is because a charge loss from a floating gate is originated from not only intrinsic mechanism but also lateral electric field between the neighboring cells. From the electric field simulation, we can find that the electric field is increased and it results in the increased charge loss as the device is scaled down.

Objective: The objective of this study was to evaluate the effect of sodium diacetate (SDA) on fermentation profile, chemical composition and aerobic stability of alfalfa (Medicago sativa L.) silage. Methods: Fresh alfalfa was ensiled with various concentrations of SDA (0, 3, 5, 7, and 9 g/kg of fresh forage). After 60 days of the ensiling, the samples were collected to examine the fermentative quality, chemical composition and aerobic stability. Results: The application of SDA significantly (p<0.05) decreased silage pH with the lowest value in silage with 7 g/kg of SDA. The proliferations of enterobacteria, yeasts, molds and clostridia were inhibited by SDA, resulted in lower ethanol, propionic and butyric acid concentrations and dry matter loss in SDA treated silages than control. The increasing SDA linearly decreased free amino acid N (p<0.001), ammonia N (p = 0.018) and non-protein N (p<0.001), while linearly increased water soluble carbohydrate (p<0.001) and peptide N (p<0.001). It is speculated that SDA accelerated the shift from homofermentative to heterofermentative lactic acid bacteria during the silage fermentation, indicated by lower lactic acid production in SDA-9 than SDA-7 silages after 60 days of ensiling. Alfalfa silages treated with SDA at 7 g/kg had highest Flieg's point and remained stable more than 9 d during aerobic exposure under humid and hot conditions in southern China. Conclusion: SDA may be used as an additive for alfalfa silages at a level of 7 g/kg.

The main purpose of this investigation is to make up for the limitations of parcel addressing and to seek the application plan of cadastral triangulation point to effective installation of national index numbers. The test-bed has been constructed at the mountainous area located in Nowon-gu, seven cadastral triangulation points within the test-bed was directly applied to this investigation. Each points have been firstly converted from a plane rectangular coordinates to a single plane rectangular coordinates (UTM-K). To verify positioning results achieved from these points, a single plane rectangular coordinates through the Network-RTK was considered. With regards to verification result, maximum coordinate shift was revealed by 6 cm, this level of difference can be satisfied to Article 7, paragraph 2 "the regulation for National Index Number". This means that coordinate transformation applied with cadastral triangulation points can achieve the sastisfied result without local surveying. And also, remarkable effects have been created in terms of financial effectiveness and safe preservation of cadastral triangulation points due to the omission of local surveying.

As one of solutions to pursue the efficient use of spectrum resource, we proposed the methodology for the co-channel multi-site radar operations with the synchronous GPS clock. The proposed algorithm, based on a quasi orthogonal property, find a candidate set of the time shifted linear frequency modulation(TSLFM) signals with the minimum acceptable level of the correlation among selected TSLFM signals. To check suggested algorithm, numerical analysis for several radars operating in the same channel with a sawtooth waveform has been performed by using range-Doppler processing for the given system parameters, and computational results are presented and examined in terms of range profile and doppler shift for a targets with velocity and distance. Simulated results have a good agreement with assumed target distance and its velocity, within the error of resolution.

This study was done to identify the influence of emotional labor, job stress and burnout on somatization of nurses live in convergence era. The participants were 387 nurses in D hospital. The average mean score for emotional labor was 3.25, occupational stress was 3.60, burnout was 3.10, and somatization was 2.18. For relations with general characteristics, there was a statistically significant difference in somatization according to age, marital status, educational level, work unit, total clinical career, present department career, position, monthly salary, shift and job satisfaction. Somatization was found to be in a significant positive correlation with emotional labor, occupational stress and burnout. As a result, factor influencing somatization was burnout. This predictor accounted for 29.6% of variance in somatization. The findings of this study showed that burnout was major influencing factor on somatization of nurses. Therefore, it is necessary to develop strategies that can reduce somatization by controlling burnout.

In this paper, we propose an excellent ultrasonic transceiver system based on a QPSK modulation technique for underwater communication. The transmitter sends a still image at the level of 187dB re $1{\mu}Pa/V@1m$ through a power amplifier by driving an ultrasonic sensor. The receiver performs digital conversion at the 100kHz sampling frequency, demodulation and decoding process for the image sent from the transmitter through the underwater communication. We have shown that the processed image at the receiver is almost the same as the orignal one. The maximum detection distance of the system proposed in this paper is approximately 1.17km. To cope with the difficulties of transmission loss, this paper proposes, implements and analyzes important parameters of sensors and circuits used in the system. Most of the underwater communication has focused on the transmission of audio signal, but this paper suggests an efficient underwater communication system for still image transmission.

Canine pyometra generally occurs in intact female dogs of more than four years of age. However, in rarely cases, pyometra can occur in young bitches. In the present report, two cases of pyometra in thirteen and eighteen months of age were presented. In both cases, absent of vaginal discharge represented that both patients had closed-cervix pyometra and diagnosis was somewhat complicated. In complete blood count, elevated level of leukocyte with left shift was found in both cases. Serum chemistry analysis showed elevation of alkaline phosphatase in both cases. Additionally, mild elevation of aspartate transferase and total protein were also found in $2^{nd}$ case. Radiographic and ultrasonographic findings show the enlargement of uterus and accumulation of fluid contents inside the uterine lumen. Ovariohysterectomy followed by antibiotics and anti-inflammatory drugs for post-surgery medication was performed for treatment. After a week, both patients fully recovered. To reduce mortality of pyometra in young intact female dogs, radiography or ultrasonography should be indicated immediately in the bitches showing severe infectious inflammation.
