  • As a demand for an automobile increases, air pollution and a problem of the energy resources come to the fore in the world. Consequently, governments of every country established ordinances for green-house gas reduction and improvement of air pollution problem. Especially, as international oil price increases, engine using clean energy are being developed competitively with alternative transportation energy sources development policy as the center. Bio ethanol, one of the renewable energy produced from biomass, gained spotlight for transportation energy sources. Studies are in progress to improve fuel supply methods and combustion methods which are key features, one of the engine technologies. DI(Direct Injection), which can reduce fuel consumption rate by injecting fuel directly into the cylinder, is being studied for Green-house gas reduction and fuel economy enhancement at SI(Spark Ignition). GDI(Galoine Direct Injection) has an advantage to meet the regulations for fuel efficiency and $CO_2$ emissions. However it produces increased number of ultrafine particles, that yet received attention in the existing port-injection system, and NOX. As fuel is injected into the cylinder with high-pressure, a proper injection strategy is required by characteristics of a fuel. Especially, when alcohol type fuel is considered. In this study, we tried to get a base data bio-ethanol mixture in GDI, and combustion for optimization. We set fuel mixture rate and fuel injection pressure as parameters and took a picture with a high speed camera after gasoline-ethanol mixture fuel was injected into a constant volume combustion chamber. We figured out spraying characteristic according to parameters. Also, we determine combustion characteristics by measuring emissions and analyzing combustion.

  • Prisons are mostly filled with social deviants and like other correctional institutions, deserve organized information (provision) centers such as library. A study on library resource needs and accessibility by prison inmates was conducted at Kuje prison, Abuja and Kaduna prison, Kaduna, Nigeria, both of which have functional libraries. A sample of 898 inmates was randomly selected from all the convicted inmates in the two prisons. A total of 106 inmates were selected from Kuje prison and 792 from Kaduna prison. A well-structured questionnaire was used to collect data from the inmates. All the 898 inmates responded. A total of 786 (87.9%) males and 112 (12.4%) females were involved in the study. With regards to the educational level attained by the inmates, 347 (38.6%) had Junior Secondary School Certificate while 323 (30.0%) had Senior School Certificate both accounting for 74.6% of the sampled population. In areas of information needs, 94.5%, 96.1%, 98.7%, 99.4%, 100%, and 100% of the respondents indicated that information on current affairs, survival and coping, educational support, legal aid, skill acquisition, and health, respectively were highly needed by the inmates. Out of the 12 information resources listed, only newspaper, novel, handbook and manual, and bulletin were readily accessible with percentage accessibility of 60.7, 7.8, 6.8, and 1.9, respectively. One major reason adduced by the respondents for limited access to information resources was the very strict rules and regulations in the prison. Providing more library resources and granting the inmates more access to the library would assist in character reformation and rehabilitation of the inmates.

  • The purpose of this study is to discuss Joseon dynastyis first perspective on the Western-style Court Costume which was newly introduced to Joseon through the problems receiving the credential that Japan had sent in new style. For this study, the records of Joseon and Japan at that period have been analyzed. The followings are the results of this research; First, a critical argument on the Western-style Court Costume occurred just before the Port Opening because whether wearing a western costume was the key factor in Joseon dynastyis receiving the credential that Japan had send in new style. Second, Japan received western costume as its domestic courtesy system by establishing the Court Costume of Civil servants in 1872 and consequently Japan established new ceremony procedure of western-style bow in 1875. Third, Joseon dynasty officially opposed to the Western-style Court Costume when Japan sent the credential, because the western costume selected by Japan had beenregarded as that of western barbarian at that time in Joseon. Accordingly, it seems reasonable that before the introduction of western costume into Joseon dynasty, an open-door policy for the West had been a prior settlement for Joseon dynasty regardless of the details of Western-style Court Costume. And also, the pride of civilization of Joseon dynasty, which has been used to express Joseon dynastyis identity as Joseon-centrism, had to be converted before the open-door policy. Ultimately, it could be inferred that the reception of the Western-style Court Costume had been raised as the political and diplomatic problems in the circumstances when the submissive relationship in the traditional Eastern- Asia had been forced to be converted to modern sovereign international relationship.

  • Much efforts have been made to improve the training education system for last decades. however, it still leaves much room form improving the system. The reason for this is that the have been many changes in given educational conditions, national and international, and that there existed the lack of training facilities on shore and the limits of capacity on the training ship. The existing program adopts a straight-through system of which the course has to be completed at same time, and also forces students to study the course, disregarding their aptitude for sea life. Consequently, the program resulted in frustrating the learning desire of some students and, as a consequence, in deteriorating the quality of the entire training education. This paper aims to develop an efficient training program including curriculla by the literature survey and the teaching and sea experiences on the training ship "HANBADA" and merchant ships, where the authors have been for many years. Compared with the existing one, the new training model suggested in this paper has some advantages as follows : First, the new model adopts multi-state system which consists of various short-term training courses according to each purpose. This system will be helpful for student to find their aptitude for sea life earlier and to understand classes of major subjection shore. Second, the model includes new curriculla which consist of core subjects (for example, navigation, marine operation, marine transportation, watch keeping and nautical English for deck cadets and internal and external combustion engine, auxiliary machinery, electric and electronics and engine maintenance for engine cadets), by incorporating existing 20 subjects in 5 subjects. These curriculla may contribute to embodying the characteristics of training education where the above mentioned subjects must be linked with each other. In order to implement this new training model efficiently and effectively, the following prerequisties must be prepared : $\circled1$ The contents of each subject included in the new model should be systematically developed. $\circled2$ The educational schedule should be adjusted according to the new model.new model.

  • Masan barber was situated in S.Korean southern central coast. And it is contributing greatly in S.korea's economy development to international trading port of Heaven's blessing that possess natural, geographical situation. Also, because there are Masan free tax area and chanwon heavy industrial complex, sachon air industrial complex etc. on back, it is important permanency in our country. Specially, because inland transport routes such as southern highway, Guma highway and national road system are developed well, the importance is very high. Masan harbor 1899.05.01 be that opened, the 1st and 2nd (central pier) was build 1938∼1944 year, and the 3rd pier was 1973∼1978 year. the 4th pier was 1974∼1983 year, 5th pier was 1984∼1988, 6th pier (west pier) was 1985∼1992 year. it was developed over 100 years. But, it did great many harbor and bay development of last 100 yens but research about coastline change and seashore reclamation is insufficient. Therefore, this research executed research about coastline change of Masan bay of last 100 years, In this study, we analyzed aerial photographs and tide data for the past 100 years using digital aerial photo analysis and GIS techniques for each 3-year interval. We abstracted beach DEM (digital elevation model) and ortho aerial photographs, and conducted a space analysis. As a result, we were able to identify changes in the area As a result, we drew 10 years cycle coastline change of Masan bay. and we can detect bay coastal line change and calculate refill rate.

  • Purpose - Semiconductors are a significant export item for Korea that is expected to continue to contribute significantly to the Korean economy in the future. Thus, the semiconductor industry is a critical component in the 4th Industrial Revolution and is expected to continue growing as the non-face-to-face economy expands as a result of the COVID-19 pandemic. In this context, this paper aims to empirically investigate how semiconductors are imported and exported in Korea from a global supply chain perspective by analysing import and export data at the micro-level. Design/methodology - This study conducts a multifaceted analysis of the global supply chain for semiconductors and related equipment in Korea by examining semiconductor imports and exports by semiconductor type, year, target country, mode of transportation, airport/port, and domestic region, using import/export micro-data. The visualisation, flow analysis, and Bayesian Network methodologies were used to compensate for the limitations of each method. Findings - Korea is a major exporter of semiconductor memory and has the world's highest competitiveness but is relatively weak in the field of system semiconductors. The trade deficit in 'semiconductor equipment and parts' is clearly growing. As a result, continued investment in 'system semiconductors' and 'semiconductor equipment and parts' technology development is necessary to boost exports and ensure a stable supply chain. Originality/value - Few papers on semiconductor trade in Korea have been published from the perspective of the global supply chain or value chain. This study contributes to the literature in this area by focusing on import and export data for the global supply chain of the Korean semiconductor industry using a variety of approaches. It is our hope that the insights gained from this study will aid in the advancement of SCM research.
