  • This paper describes the political and technical trends of foreign 10 countries advanced in solar energy field. In the trend analysis, a couple of statistical data and related references were compared. As a result, all of the advanced countries mentioned in this paper have their own PV policy strategies and regulatory frameworks to strengthen their stable market structures and have financially supported by various types of incentives and tariff systems. It was confirmed that the political basis and technical regulations including electrical safety have to be prepared as soon as possible at both national and rural level in this country.

  • In this thesis considering the problems shown in the usage of interlining of clothes and in the process of sewing the breaking away strength which is meant by adhesion is analysed by experimennt in which Polyamide content is dealed with at the 5 level to raise the adhesive strength by using the one-sided non woven adhesive interlining made in this country as the samples. After examing the optimum in the process of Cotton and polyester fabrics and adhered fabrics practical for blouse and jacket and analysing the breaking away strength the wanted property of matter and the change with the repeated laundry We reach at the following results. 1. The adhesive strength of the two adhered fabrics were strongly appeared in order of cotton>polyester. 2. The order of the breaking away strength by the interlinings of adhesive fabrics was A5> A4> A3> A2> A1. 3. The breaking away strength of the two adhered fabrics was weakened by the repeated laundry and the breaking away phenomena were fewer under the most suitable conditions than the various conditions.

  • As 10th energy consumption country in the world, it is very important to educate the importance of the energy to the elementary school students. The purpose of this class is to let the pupils understand the mechanisms and performances of tidal power generation as a renewable energy application system. To satisfy the educational goals, a lecture material and a simple type of tidal power generator kit is developed. As the survey result after lecture and experiments which include assembly and test, 'Well understood' is marked as 90% among 58 elementary students, and moreover 70% among them feel to participate in higher level course. This project shows the possibility and effect of the renewable energy education course as a service engineering, which is managed and carried out by undergraduates for pupils under the professor's guide.

  • Recently, Increase of energy consumption is continued accordingly because economy is constant growth. so we need long term of energy supply stability and develop new energy source. The effort of environmental improvement is necessary and our country has to educe conservatory gas in these situation, our energy policy is summarized that minimizes energy consumption and uses kinds of energy source. This paper studied some effort of stability that distributed generation put in electric system through line fault, sudden load change. And then this paper calculated penetrated level of distributed generation in system transient stability.

  • Port in Northern Vietnam has been playing an important role in the logistics system the country. In recent years, the cargo throughput of the region, especially, containerized cargo has increased gradually. There are totally 11 container terminals in Northern Vietnam, concentrating in Haiphong city and Quang Ninh province. Despite of increasing demand, the competition among the terminals is becoming more and more critical. The paper, firstly, summarizes factors impacting the market share of the terminals before reveal the correlation between given factors and annual container throughput. Factor analysis will be then applied to evaluate the level of terminals' logistics infrastructure. For the conclusion, strategic thinking of terminals' logistics competitiveness will be contributed to related organizations.

  • According to the reports by the OECD and UN in 2012, Korea is evaluated highly of its enthusiasm and level of education compared to other evaluation indices. This result implies that Korea has much more interest in education than other countries. In reality however, the nation does not provide an adequate condition in other aspects such as the quality of life of citizens and its educational environment. For this reason, our country currently promotes and operates various policies and environmental improvements in an effort to coincide with the timely demands and to cope up with the advanced educational system. Researches in particular are being implemented on Korea's current educational policies by specialists related to their specific fields. This study is to understand the periodic trends of the educational facilities according to the specialist-oriented articles and apply it as a basic resource to the future researches on the corresponding field.

  • A few recent international surveys reported that Korea ranks the top with respect to the high-speed information and communication network subscription per 100 people in the world. Such infrastructure has been bringing about broad changes in Internet service for both business and individual users. By conducting a questionnaire survey on a moderate size of sample proportional to the population of each region across country, we try to analyze what factors might explain the level of Internet service satisfaction with respect to security, searching, and convenience dimensions. According to the test results, several factors such as sex, age, kind of network lines, usage frequency, e-mail usage, e-shopping, online problem experience might explain the different levels of Internet service satisfaction in the high-speed Internet network. This study might shed a guidance to scholars conducting Internet-related studies and practitioners who plan information policies and business strategies.

  • This paper shows the latest trend of coping plan for mitigating lightning damage in advanced countries. The mitigation measures were investigated in following fields: the organization of government and warning system, education and publicity, support program and concerned service. In results of investigations, the USA and Japan have been organized with the latest technology of warning system and the effective management of organization. So government-level mitigation measures based on the small-scaled lightning warning system need to be considered for reducing the damage of lightning in our country.
