The paper will investigate the chances of progress in the peace process in Middle East. Robert Hazo's 1993 article mainly argued the Palestinians and Syrian problems. He saw that these two problems are one of the key issue that current Middle East problem which involves Israel. The key tenants of his argument will be dissected to assess whether this view holds true in the light of developments in the Middle East in the intervening years. The Arab-Israeli struggle remains one of the most intractable in history. In 1993 Robert Hazo concluded that 'the conflict is a terminal struggle'. This paper investigates his analysis in light of progress or lack of in the intervening period and against the contemporary strategic environment. It uses information presented in academic, government, newspaper and world wide web articles to conclude that Hazo's assessment remains valid. While the various talks since 1993 combined with the potential benefits the United States, Israel and Syria could gain from a settlement proffer hope, the issue of 'right of return, borders and Jerusalem are unlikely to be bridged in the near future.

This study aims to identify the representation of migrants in the English-language media during the Brexit campaign period. For the purpose of this study, the methodological tool of corpus-assisted discourse studies(CADS) was employed and a collection was compiled of articles mentioning Brexit in British, American, Canadian, and Australian media from April 15 to June 22, 2016 in order to compare their portrayals of migrants. To examine how IMMIGRANT, MIGRANT, and REFUGEE are represented in the media, their collocates were analyzed by MI score and categorized by social actor categorization(Van Leeuwan, 1996). The results show that IMMIGRANT is related to collocates that refer to legal status and provenance, MIGRANT associated with economic terms, and REFUGEE relates to terms expressing quantities. The results also reveal that migrants are frequently depicted by functionalization, classification, and appraisement categorization and are more negatively portrayed in British and American media. This paper claims that corpus-assisted linguistic analysis of words enables one to identify salient linguistic patterns or lexical choices in the discourses about a particular phenomenon or group of people.

Recently, there is a growing interest in network anomaly detection technology to tackle unknown attacks. For this purpose, diverse studies using data mining, machine learning, and deep learning have been applied to detect network anomalies. In this paper, we evaluate the decision tree to see its feasibility for network anomaly detection on NSL-KDD data set, which is one of the most popular data mining techniques for classification. In order to handle the over-fitting problem of decision tree, we select 13 features from the original 41 features of the data set using chi-square test, and then model the decision tree using TensorFlow and Scik-Learn, yielding 84% and 70% of binary classification accuracies on the KDDTest+ and KDDTest-21 of NSL-KDD test data set. This result shows 3% and 6% improvements compared to the previous 81% and 64% of binary classification accuracies by decision tree technologies, respectively.

In this paper, an antenna applicable to WLAN and WiMAX frequency bands is designed, fabricated, and measured. The proposed antenna is designed to have two branch strip line in the patch plane and a rectangular slit in the ground plane based on microstrip feeding for triple band characteristics and added a vertical strip in the ground plane to enhance impedance bandwidth characteristics. The proposed antenna is designed on a substrate with a relative permittivity of 4.4, a thickness of 1.0 mm, and has a size of $18.0mm(W1){\times}37.3mm$ (L4+L5+L7). From the fabricated and measured results, impedance bandwidths of 480 MHz (2.32 to 2.80 GHz) for 2.4/2.5 GHz band, 810 MHz (3.22 to 4.03 GHz) for 3.5 GHz band, and 1,820 MHz (5.05 to 6.87 GHz) for 5.0 GHz band were obtained based on the impedance bandwidth. Measured 3D pattern and gains are displayed.

Ten middle-aged women who support their biological parents have been interviewed to investigate their experiences of caregiving their parents. As a qualitative research method, data were collected through in-depth interviews and analyzed by Colaizzi's phenomenological method. Consequently 244 meaningful sentences were selected from the collected interview data and then were sorted into 67 meaningful sentences and, consequently into 9 sub-themes. Finally four high-level themes are wrapped through the summarizing process. The first theme is motivation of caregiving. Inevitable cases are most common for caregiving their biological parents. And, general responsibilities to their parents are also deduced as a motivation of caregiving. The second theme is a psychological phenomenon of middle-aged women while they provide consistent caregiving their biological parents even though they have some troubles with their parents. The third theme is meaning of caregiving. For some women, caregiving their biological parents is their own happiness and gratitude such as lifelong gifts. The final theme is influence of caregiving. Further understanding their parents, and more distinct prospecting their future lives are unexpected fruits from the caregiving their biological parents.

The purpose of this study is to investigate factors affecting turnover intentions of rehabilitation specialists by using data on the "improvement of labor conditions and human rights of rehabilitation Specialist" which was conducted both in 2016 and in 2017. The turnover intention of the rehabilitation specialists was analyzed with personal factors, job-related factors, and factors related with client violence, discrimination, and burnout. Among these factors, variables of wage satisfaction, job satisfaction, and client violence have statistically significant effect on the turnover intention of rehabilitation specialists. While the variables of wage satisfaction and job satisfaction are likely to decrease the turnover intention of rehabilitation specialists, the variable of client violence significantly increase the turnover intention of rehabilitation specialists. The results of this analysis implies that the labor conditions including salary, the work environment for the rehabilitation specialists, and client education should be improved and strengthened to decrease the turnover intention of the rehabilitation specialists.

In this paper, we propose an ordering chatbot that can process multiple keywords based on recursive slot-filling method. In general, in case of an order service using chatbots, the whole order process is performed only according to the sequence defined by the developer. That is, among all the information needed for the whole order process, only one input can be processed at one time. In order to reduce processing step for the order, we propose a recursive slot-filling method which fills out multiple slots per one time by extracting multiple keywords. First, a keyword array for the order is created according to the order related information. Next, from the input sentence of a user, multiple keywords is extracted. Corresponding slots for a keyword array will be filled with the extracted keywords. Finally, recursive routine will be executed to fill out all the blank in the keyword array. The usability and validity of the proposed method will be shown from the implementation of a smartphone application.

The embryonic development and hatchability of the artificially fertilized eggs of convict grouper (Hyporthodus septemfasciatus) ♀${\times}$giant grouper (Epinephelus lanceolatus) ♂ (CGGG) were compared to those of the maternal pure species (convict grouper ♀${\times}$♂, CG) to establish a novel grouper hybrid for aquaculture industry. The fertilized eggs were divided into nine 5-L beakers (3,000~5,000 eggs/beaker) filled with UV sterilized seawater and incubated at a temperature range of $23.5{\sim}24.8^{\circ}C$ (32.1~32.8 psu). The percentages of fertilization and hatching of CGGG were $69.4{\pm}1.5%$ and $59.0{\pm}5.1%$, respectively and were significantly lower than those of CG (p<0.05). The CGGG proceeded normal embryonic development similar to that of CG, but showed an irregular cleavage, immature embryonic body and spinal deformity in hatched larvae. The incubation time from fertilization to hatching of CGGG was 31 hrs, which was approximately 2 hrs slower than that of CG. Our study provided the possibility of mass production of grouper hybrid CGGG larvae.

The purpose of the paper is to suggest the empirical evidences for the effects of factor prices on the export performance in the Korean manufacturing industries during the period 1975:1-2016:4. The paper is to set up the error correction model derived from the autoregressive distributed lag scheme and to estimate the factor price elasticities of export in the 8 manufacturing industries. The real wage, interest and import price index elasticities of export all were estimated to be statistically significant at 1% level in the most industries with showing negative signs as expected. And the real wage elasticity proved to likely be smaller as the industries become more capital-intensive while the import price index elasticity tended to become larger in industries with larger ratio of imported intermediate goods to output. The empirical results suggest that the declines in input factor prices since the foreign exchange crisis in the end of 1997 have positive effects on the export performance in the Korean manufacturing industries.
