  • Mutant rice cv. Goami2 (G2) and Baegjinjoo (BJJ) derived from a high-quality japonica rice cv. Ilpumbyeo (IP) were extruded under different feed moisture (20 and 30%) and barrel temperature (90, 110, and $130^{\circ}C$). Increasing feed moisture at fixed barrel temperature increased extrudate density (ED) in IP and BJJ. Whereas, G2 showed a varied ED depending on extrusion conditions; increasing barrel temperature decreased the ED of G2 extrudate with low feed moisture, but increased with high moisture. Results indicated a positive barrcl temperature effect on volume expansion in IP and G2, but a negative effect on 811, probably due to shrinkage of expanded products containing low-amylose contents. A significant increase of water absorption was found in G2 and BJJ extruded flour, while an increase of water solubility in those from IP. Non-digestible carbohydrates measured by total dietary fiber (TDF) indicated that extrusion increased slightly TDF in IP and BJJ extrudates, but decreased in G2 products, which might be variety-dependent.

  • Interest in and study on 3 dimensional pictures has been continued since visual media showing moving images was invented. From simple anaglyph wearing glasses to hologram making perfect 3 dimensional objects by recording phase data of reflected light, as well as amplitude and wave, speed and scope of technical development are quicker and wider, respectively. However, despite such development of technology, there is still lack of study on aesthetical, industrial and contents developing area, except for technology of 3 dimensional images. Unlike the interest in 3 dimensional images, even a theoretical frame for the approach to theoretical areas of 3 dimensional images has not been established. Especially, few experiment and study on directing aesthetics have been conducted, with exception of areas in entertainment documentaries for 3 dimensional feeling or some latest 3D animations. As a result, this study will try to find alternatives to directing aesthetics of realistic 3 dimensional movies to be developed in future by studying directing grammar and aesthetics of digital 3 dimensional movies and finding and analyzing difference between 3 dimensional images and 2 dimensional images drawn on the plane.

  • It is not easy to access to the required data from the Web by using search engines because there are too many data selected and they do not provide enough information related to the corresponding data. Metadata is data about data. It includes information about data itself and contents of data as well. Users can acquire enough information about the corresponding data and access to the required data exactly using metadata, and therefore the data usability will be increased. In this paper, several metadata technologies and metadata models that are already in process of standardization or adopted as standards are analyzed, and the SeriCore Metadata Model for documents such as papers, project reports, technical reports, abstracts, and manuals, and graphic images that are in the field of science technologies on the Web is proposed. The SeriCore Metadata Management System that can generate, store, and retrieve metadata effectively is designed and implemented based on the SeriCore Metadata Model.

  • Due to the expandability of smartphone, the mobile application market is growing explosively. However, as happens in other digital contents markets, piracy of mobile applications is prevalent. This study investigated the effects of behavioral factors on smartphone application piracy. The research model consists of factors from the theory of planned behavior model - subjective norms, attitudes toward piracy and perceptions of behavioral control. In addition, perceived consequences, past behavior and habit was included. The past behavior of PC software piracy was a meaningful predictor of habit, and habit was found to influence significantly the smartphone piracy intention. The result also shows that perceived benefit had significant effect on attitude, but both perceived legal and technical risk were not significantly related to attitude. Implications for research and practice are discussed.

  • Objectives : A survey was conducted to investigate oral health belief and education awareness of oral health of workers in the workplace and to obtain the basic data necessary to promote their oral health and design an oral health education program. Methods : This study conducted a self-administered survey. Results : The following conclusion was made. For oral health beliefs based on the type of work that the workers did, workers in production and technical services had more benefits than those in other fields(security, guard, etc.), and workers on night duty had more oral health hygiene problems than that of regular day-time workers. The longer the period of service was, the more sensitive and serious the workers were and the less beneficial the work was; workers working for eight hours or less had higher levels of importance than those working for ten hours. They were well aware of the need for oral health education but were less aware of the need for an oral health room. Conclusions : It is necessary to emphasize oral health beliefs when developing an oral health education program that promotes oral health for workers in the workplace. If an oral health education program attempts to reflect the concerns of workers in the workplace and provides preferred contents and methods on oral health education, the program is expected to promote the active and positive participation of the workers.

  • The updated International Standard Banking Practice(ISBP), International Chamber of Commerce Publication No. 745, was published to bring its contents in line with UCP 600. The ISBP 745 has dealt with A-Q that are commonly arising in the credit transactions and also explains in detail some of the articles of UCP 600 with the proper interpretation. The updated version ISBP 745 involved aligning it with UCP 600, making certain technical adjustments in expression of words such as "in conflict" instead of "inconsistent", etc. Despite the updated ISBP 745, there remains a question. Where the words "from" or "after" are used in regard to something other than a period of shipment or the maturity date of drafts, there is no guidance from the UCP as to its meaning. The party concerned in credit transactions is also required to have a full understanding of ISBP 745 and the articles of UCP 600 in order to acquire the documents preparation and examination facilitating the parties to minimize discrepancies.

  • Specialty contractors are in charge of the actual construction work and managing many work force in construction sites. The effective educational program for specialty contractors' employees is essential to improve the competitiveness of construction industry. However, there is no in-depth research on training programs for their management or technical staff. Therefore, this study proposes a framework of educational program for the specialty contractors' employees in order to enhance their competence. An extended review of literature related the educational program was carried out to understand the concept, structure, and element of the education system. A questionnaire survey for specialty contractors' employees was performed to investigate the status and problems of educational programs as well as the their educational needs. Based on the survey, the demand-oriented education programs is required to meet the needs of specialty contractors' employees. The framework of demand-oriented education programs for specialty contractors' employees consists of training contents, training type and method, training hour.

  • Objective: This study aims to introduce the bridge resource management (BRM) training courses implemented in Korea and to analyze their effectiveness in several views. Background: BRM training will be a mandatory course for crew members of ships from 2017. At this stage, it is needed to check if the BRM training courses implemented until now was effective to the Korean maritime safety and to investigate if there are more effective training methods. Method: The effectiveness of BRM training intervention in Korea was compared with that of the other countries, using Kirkpatrick's (1976) training evaluation framework. Kim (2012)'s data on the BRM training effectiveness were re-analyzed in order to check if the effects of BRM training are dependent on the bridge work experience. Results: Many BRM training courses has been opened in Korea. However, the methods to assess BRM training effects used in Korea focused on the survey of subjective satisfaction level, not investigating trainees' attitude and behavior change. On the other hand, the effectiveness of BRM training was higher to the bridge officers with long work experience than with shorter work experience. Conclusion: The contents of BRM training should be changed to effectively apply to the context of the real-world exercise and be differentiated depending on the work experience. Research on the methods to measure the BRM training effectiveness is also more required. Application: The results of this study will aid to develop the BRM training courses for bridge officers of ships in the BRM training institutions.

  • This paper has surveyed above all what the patients call for physically, psychologically, and socially and researched how the ministers have acknowledge on cancers, their patients and hospice by means of enquete. To the difficulty the pastors should give their hands. This study researched what thoughts and behaviors the ministers actually had by the method of questionnaire. It was done from October 20, 1997 through December 10, 1997 on seven thousand of questionnaire paper of which 149 given back on the line of post or firsthandly were analyzed. The questioness consisted of 141 men(94.6%), 8 women(5.4) and 104 pastor on appentice(69.8%). There were 58 questionees(38.9%) who were hospitalized of their own diseases, and 121 questionees(81.3%) who had cancer patients hospitalized among their church people, relatives, or friends. Most of all the questionees(79.9%) had not any experience, such as they took some instruction about cancer patients. 72.5% of all the questionees had not ever served patients around them. The followings are the contents of the enquete: the questionees' view to chronic patients and death, where they put the priority in the case of that they look after patients who are under terrible pain ahead of death, what they think of such a situation as a patient has no technical possibility to be recuperated, why they think pastors do not like to visit chronics, which therapy they choose, whether they mainly control their pain or they do their best in order to heal their diseases, how much the questioned ministers know hospice, where and how they get the information on it, how much important role they play in the hospice team, whether the volunteers for hospice have not worked on account of pastors' misunderstanding to hospice service, whether the ministers want to take part in hospice service with their church people or not, and so forth. Suggestion: First, the education and P.R. about hospice are requested for the ministers. Second, the ministers must participate in hospice activities actively. Therefore the ministers and the churches must firsthandly take part in hospice activities beyond the education only and the raising of the recognition to them.
