There are technological, operational and environmental constraints at tactical edge, which are disconnected operation, intermittent connectivity, and limited bandwidth (DIL), size, weight and power (SWaP) limitations, ad-hoc and mobile network, and so on. To overcome these limitations and constraints, we use service-oriented architecture (SOA) based technologies. Moreover, the operation environment is highly dynamic: requirements change in response to the emerging situation, and the availability of resources needs to be updated constantly due to the factors such as technical failures. In order to use appropriate resources at the right time according to the mission, it needs to find the best resources. In this context, we identify ontology-based mission service model including mission, task, service, and resource, and develop capability-based matching in tactical edge environment. The goal of this paper is to propose a capability-based semantic matching for dynamic resource allocation. The contributions of this paper are i) military domain ontologies ii) semantic matching using ontology relationship; and (iii) the capability-based matching for the mission service model.

Background: Head and neck cancer (HNC) is the ninth most common cancer worldwide, and has a poor 5-year survival rate averaging 50%, which has not changed for decades. A high prevalence of HNC has been reported in the southwestern region of Saudi Arabia, as compared to other areas of the country. However, data in regards to HNC are scattered and not well documented. Thus, the aim of this systematic review was to gather all available and updated important information regarding HNC in Saudi Arabia, and highlight the gaps of knowledge in our country with regard to this disease. In addition, suggestions of solutions to overcome the current status and improve our future standard of care to fight HNC are also highlighted. Materials and Methods: The electronic databases PubMed and Google Scholar using English-language literature were used for this systematic review, using specific inclusion and exclusion criteria and keywords. The search was performed in April 2016 and updated in June 2016. Results: Our search revealed twenty-one studies that fulfilled our inclusion and exclusion criteria and that were conducted in Saudi Arabia. These studies investigated different aspects of HNC, including prevalence, risk factors, biomarkers, and assessed knowledge and awareness of both public and practitioners with regard to HNC. Conclusions: This review uncovered a big gap in our epidemiological data in cancer information in general, and head and neck cancer in particular. In addition, a lack of knowledge and awareness of both the public and health care practitioners hinders the early diagnosis of disease and negatively impact the prognosis, treatment and outcome. The Ministry of Health in Saudi Arabia should develop a more systematic way and adapt policies to gather cancer information in general, and head and neck cancer in particular, from all governmental and private sectors from all over the kingdom, and develop educational programs to raise the knowledge and awareness of HNC in the country.

The convergence of telecommunications and broadcasting is representative of many innovative technologies in the digital environment. It has recently been emphasized as an alternative solution to overcome the on-going saturation of the telecommunications and broadcasting markets. Despite this effort, however, growth of the market and its related services cannot reach prior expectations due to lack of understanding on the real user-end. Telecommunications technology used to serve its instrumental purpose and broadcasting services usually support entertainment functions which in themselves have an inherent value. Our research questions what factors influence users' attitude and decision-making when it comes to using telecommunications-broadcasting convergence services. The research model of this paper proposes intrinsic motivator focusing on hedonic value, extrinsic motivator having utilitarian values, and perceived control as internal and external conditions. To verify our model empirically, we selected the DMB technology which is a good example of distinctive telecommunications-broadcasting convergence service.

How to facilitate Integrated Marketing Communication (IMC)? An approach to answer this question is to identify an organization's internal and external barriers to IMC and then to resolve them. Eight dimensions emerged from the factor analysis of the barrier items: organizational structure problem, department ego, lack of database, difficulty in analyzing effectiveness, lack of perception on consumer-oriented communication, increasing dependency on an agency, lack of agencies' expertise on IMC, and fear of budget reductions. With regression analyses, this study found that 'organizational structure problem' and 'lack of perception on consumer-oriented communication' were negatively related to IMC and that 'department ego', 'lark of perception on consumer-oriented Communication', 'organizational structure problem', and 'fear of budget reductions' were negatively related to the expectation of IMC usefulness. The findings indicate that organizations surveyed stay at a low level of IMC and urgently needs to resolve internal barriers rather than external ones in order to enhance IMC.

This paper is studied on the effect of the bolt joint stiffness on the Thrust Measurement Stand(TMS). TMS is a test stand for thrust performance of the propulsion system, which depends on two factors: The $1^{st}$ is the parallel degree between directions of the thrust vector and action lines of the corresponding measuring load cells for the vector, and the $2^{nd}$ is the orthogonality between action lines of the measuring load cells. Therefore, it is essential to maintain the original shape of the TMS under operating conditions. In this paper, it is examined how the geometric tolerance of the bolt joints and threads of the load cell trains affect the performance of the TMS. Also, some techniques to overcome related problems are proposed.

We are suggesting a new index to represent the performance of PDP, such as Specific Performance Index (SPI) that includes luminous efficacy and panel reflectance. High Xe gas mixture and low panel capacitance are well known as key factors to improve luminous efficacy of PDP [1]. However, higher driving voltage and longer discharge time lag is an obstacle when applying these technologies. Modified cell design, new materials and driving waveform enable us to overcome these obstacles. High efficient phosphor is also a key material to improve luminous efficacy. Phosphors coated with pigment are used to reduce panel reflectance. High performance 50-inch HD PDP with luminous efficacy of 2.3 lm/W has been developed.

Road signs are guide facilities for road users, and the Ministry of Land, Infrastructure and Transport has established and operated a system to enhance the convenience of managing these road signs. The role of road signs will decrease in the future autonomous driving, but they will continue to be needed. For the accurate mechanical recognition of texts on road signs, automatic road sign recognition equipment has been developed and it has applied image-based text recognition technology. Yet there are many cases of misrecognition due to irregular specifications and external environmental factors such as manual manufacturing, illumination, light reflection, and rainfall. The purpose of this study is to derive location-based destination names for finding misrecognition errors that cannot be overcome by image analysis, and to improve the automatic recognition of road signs destination names by using Levenshtein similarity verification method based on phoneme separation.

While many factors could be mentioned to the rapid development of Israel for the last 50 years, it could not be overemphasized the critical role of large scale influx of Jewish immigrants not only in the process of achieving national independence but to the development of modernization. It is well known that mass influx of people in a relatively short period of time may cause serious social problems in various areas such as housing shortage, increasing crime rate, etc. Nontheless, Israel is avidly recognized as a country that successfully overcome such problems by means of creating systematic social integration systems and practicing various adaptation assistance programs for new immigrants. This study was concerned with such a successful social adaptation-assistance programs of Israel for large scale immigrants those who came from all over the world with different socio-economic background. In order to answer the research questions, following two areas of topics were researcher`s main concern. First, organizational structure and functions of the Ministry of Immigrant Absorption of Israel and Jewish Agency that are primarily responsible for the economic, occupational, social, and cultural integration of immigrants during their first three years (five years for housing-aid) in Israel. Second practical adaptation assistance programs such as direct absorption basket, Ulpan, Aliyah 2000, special projects of Keren Hayesod and two of Aliyah Absorption Centers are examined. And lastly some of implications and suggestions are provided in the conclusion section in relation with social adaptation-assistance and integration of reunified Korea, especially from the point of North Koreans.

In response to complexity and diversity of a social phenomenon, the dispute also is various, therefore can not be settled efficiently by means of court adjudication to which applies a law strictly. To overcome such problems we are going to seek to make use of arbitration. According to Korean Arbitration Act Art. 3 (1), any dispute in private laws would be the object of arbitral proceedings. It could be the object of arbitral proceedings that disputes which are capable of a settlement by arbitration. It is a matter for debate that disputes containing punitive damages may be resolved by arbitration. This problem is concerning the arbitrability of the subject-matter of a dispute. To offer some solution to these issues, it is necessary to inquire into the nature of punitive damages. the policy and function of alimony, the fair apportionment of a loss. Moreover, international relations formed with international transactions should be considered. Punitive damages would be the object of arbitral proceedings as the dipute in private laws. When punitive damages pursue only punishment in the domestic arbitration that there is not foreign factors, arbitral tribunal could not make arbitral award containing punitive damages. However, if punitive damages are admitted under the rules applicable to substance of dispute, and there is the arbitration agreement in which is implied that the parties agree to submit to an arbitral award, arbitral tribunal could make arbitral award containing punitive damages in international arbitration. When it is questionable whether it is offend against our public policy or not, that we accept the effect of arbitral award containing punitive damages, and we admit the enforcement of it, we have to take the nature of punitive damages, the policy and function of alimony, the fair apportionment of a loss and the stability of international transactions into consideration.

This paper reviews the problems and opportunities of Japanese newspaper industry. In the focus are particularly issues related to causes of the crisis and reacting strategies overcoming the crisis. To answer the questions, we conducted in-depth interviews with top-level managers of major newspaper companies in Japan. Secondary data were gathered to complement the interview. Top managers mainly perceived the causes of the crisis as young readers' alienation from newspaper due to the change of media environment and structural factors such as increasing production/distribution costs and diminishing appeals for advertisers. They are implementing several strategies to overcome this crisis - developing newspaper content for young readers; packaging customized on-off line advertisement; extending news distribution via online and mobile platforms; diversifying business into diverse sectors such as real-estate; enhancing brand equity of newspaper; and collaborating with rival newspaper companies in operating news site and joint printing/distribution. Lessons from the case of Japanese newspaper industry may be useful starting points for the Korean newspaper companies agonizing for diminishing circulation and advertising revenues.
