This study was conducted to reduce sodium (Na) intake and to establish healthy dietary lifestyles of children. To achieve these goals, we searched, collected, and analyzed the materials related to the Na education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers discussed to figure out major topics, objectives, and detailed contents and activities appropriate for Na intake reduction. Also a survey was done on the sodium intake and nutrition knowledge of the elementary students. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children's textbooks and teacher's guidebooks. Considering the different cognitive development stages of junior and senior elementary students, we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of Na, Na in food, Na in life and are composed of 6 units in total. To help teachers understand and instruct, teacher's guidebook contains an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children's Na consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children's nutritional education in the field.

The aim of this study was to investigate the conditions and strategies of interaction for the school adjustment for the early entrance students of science academy for the gifted. To know their concerns and process of school adjustment, we interviewed six early entrance gifted students of the science academy and two gifted students preparing for their early entrance with a semi-structured questions. Using the grounded theory, a paradigm model was organized and a core category was abstracted through the open, axial, and selective coding. Based on the open coding analysis, 75 concepts, 21 sub-categories, and 10 categories were derived. In the axial coding, the paradigm model was organized by the link between 10 categories derived from open coding. Through the selective coding, this study discovered the core category about early entrance student's school adjustment was overcoming difficulties by using academic, social, and emotional strategy for school adjustment. Through this, we understand the school adjustment process of the students of early entrance to science academy for the gifted.

Contemporary lectures in undergraduate engineering courses typically focus on teaching major technical knowledge-based theories in a limited time. Therefore, most lectures do not allow the students to gain understanding of how the theories are applied, especially in Naval Architecture and Ocean Engineering departments. Shipyards require students to acquire practical ship design skills in undergraduate courses. To meet this requirement, two lectures are organized by the authors; namely, "Planning Procedure of Naval Architecture & Ocean Engineering" (PNAOE) and "Innovative Ship Design" (ISD). The concept of project-based and collaborative learning is applied in these two lectures. In the PNAOE lecture, sophomores receive instruction in the designing and building of model ships, and the students' work is evaluated in a model ship contest. This curriculum enables students to understand the concepts of ship design and production. In the ISD lecture, seniors learn how to develop their creative ideas about ship design and communicate with members of group. They are encouraged to cooperate with others and understand the ship design process. In the capstone design course, students receive guidance to facilitate understanding of how the knowledge from their sophomore or junior classes, such as fluid mechanics, statics, and dynamics, can be applied to practical ship design. Students are also encouraged to compete in the ship design contest organized by the Society of Naval Architects of Korea. Moreover, the effectiveness of project-based and collaborative learning for enhancing interest in the shipbuilding Industry and understanding the ship design process is demonstrated by citing the PNAOE and ISD lectures as examples.

We have prepared amide dendrons having alkyl peripheral units and various focal moieties through a convergent synthetic approach. The amphiphilic properties, due to hydrophilic amide branches and the hydrophobic peripheral units, provide an opportunity for the amide dendrons to self-organize in water. The dendritic architecture itself is also one of the critical factors in the self-organization of the amide dendrons in water. In particular, function-alization was performed at the focal point to elucidate the relationship between the focal functionality and the self-organized structures of the dendritic building blocks in the aqueous phase. The dendron having a short poly(ethylene glycol) monomethyl ether (MeO-PEG) unit (M$\_$n/ =750) as the focal moiety formed a vesicular organization in water. As the size of the hydrophilic focal MeO-PEG increased to M$\_$n/ =2,000 and 5,000, the self-organized structures became rod-type and spherical micelles, respectively. Our observation of multiple morphologies for amide dendrons is in good agreement with previous reports that indicated that the micellar structures changed from vesicles to rod-types and then to spheres upon increasing the size of the hydrophilic moiety of the amphiphiles.

Shipyard design and equipments layout problem, which are directly linked with the productivity of ship production, is an important issue serving as reference data of production plan for later massive production of ships. So far in many cases, design of a shipyard has been relying on the experienced engineers in shipbuilding, resulting in sporadic and poorly organized processes. And thus, economic losses as well as trials and errors in that accord have been pointed out as inevitable problems. This paper extracts a checklist of major elements to fine tune the shipbuilding yard designing process and the input/output data based on the simulation based shipbuilding yard layout designing framework and methodology proposed in existing researches, and executed initial architecture to develop software that integrates all the relevant processes and designing tools. In this course, both user request and design data by the steps are arranged and organized in the proposed layout design template form. In addition, simulation is done based on the parent shipbuilding process planning and scheduling data of the ship product, shipbuilding process and work stage facilities that constitute shipbuilding yard, and design items are verified and optimized with the layout and equipment list showing optimal process planning and scheduling effects. All the contents of this paper are based on simulation based shipbuilding yard layout designing methodology, and initial architecture processes are based on object oriented development methodology and system engineering methods.

The goal of this research was to identify problems associated with the management of nutrition support team (NST) in hospitals in Korea. Management status of NST in the hospitals was surveyed over the phone or interviewed by visit during August 2007. NST in foreign countries was collected by reference search and websites in the internet. Survey analysis also was performed during March, 2007 with forty-one medical staff in a university hospital located in Jinju, Kyungsangnamdo. Korean Society for Parenteral and Enteral Nutrition (KSPEN) was organized in 2001 and currently has thirty-three member hospitals with on-site NST as of August, 2007. Most of the member hospitals were big hospitals with more than 500 beds and were organized within five years. The most significant problem identified was the shortage of nutrition specialists exclusively involved in the NST. Survey analysis revealed that more than half of medical staff prescribed parenteral nutrition based on their own nutrition requirement calculation rather than consultation with NST. It appears that status of NST management of hospitals in Korea are considered to be at beginner stage and therefore, needs more aggressive advertising activity to increase consultation usage by medical staff.

The purpose of this study is two-fold. One is to provide the teachers of Home Economics with the basic reference data of the relevance between Home Economics and other subjects taught in the middle schools for the purpose of bringing out more efficient classroom teaching. The other is to help the teachers, the textbook writers, and the curriculum reformers improve the curricula of the middle school on the basis of this research. The conclusions drawn from this study are as follows: 1) The units of Human Development and Family Relationship should be taught with reference to Korean Language, Ethics, and Music. 2) The unit of Adolescence Development is dealt with in Physical Education and in Ethics as well, which seems to indicate that there was no interdisciplinary consideration and cooperation before/when the curricula were made. 3) The unit of Nutrition which appears in the first grade in Home Economics has a close relationship with the unit of Morphology and Physiology of Animals which appears in the second grade in Natural Science. It is thought that the interdisciplinary themes ought to be organized cooperatively among subjects for efficiency of study. 4) Since the unit of Clothing is not dealt with in the other subjects, ti can be developed in Home Economics on its own. 5) As the unit of Housing is closely related to Technology, it should be taught on the basis of Technology. 6) The textbooks of all subjects should be written based on the interdisciplinary research and cooperation. They should be organized in order not to overlap or repeat the same topic in the same level if it is not necessary.

Shipbome Automatic Identification System (AIS) will be an important manne equipment used for identification, surveillance and communication in the 21st century, which is currently being researched in developed countries. A technical scheme of AlS is proposed in this paper. The main component of the AlS is a broadcast transponder, and the core technology is a VHF radio data link with high capacity, named STDMA (Self-organized Time Division Multiple Access). The ships installed the AlS, which will automatically and periodically broadcast their positions and identities in the marine VHF channels, can be displayed on a screen of an ECDIS on board or in VTS centers. The AlS is able to support not only broadcast service but also point-to-point communication service. This paper presents the configuration, operation principle and functionality of the AlS as well as the scenario of STDMA. In addition, the standardization work of AlS in IMO is introduced in this pauer, too.

In this paper, the reduction amount of CO2 due to the virtual international video-conference organized by ITU in order to reduce the greenhouse gas (GHG) is calculated. The comparison is made with the case of off-line conference. In the symposium organized by ITU, "The power of ICTs to save The planet", held on September 2009 the participants were highly encouraged to attend the symposium through video-conferencing for the reduction of GHG. As a result, 46 foreign participants and 16 among 170 domestic participants have attended at virtual video-conference, which resulted in about 94.7 ton of CO2 emission reduction. This international symposium firstly tried in conjunction with online and off-line has drawn a big attention in the aspect of global warming. Definitely such ITU's trial will make significant impacts on the holding of other international symposiums and forums.

The purpose of this study is to develop and operate a curriculum which is able to connect a vocational high school to a general high school. That curriculum makes it possible to meet the necessity of accepting the learning rights for the students of a small scale school located in a rural community. And also, it is able to broaden the implementation of the elective-centered curriculum in the $7^{th}$ curriculum. So, We developed a connected curriculum model which fulfills to the utmost the requirement of a few students who want to go to a collage after finishing vocational high school and who want to get a job after finishing general high school in a electing their subjects and then operated it with student's moving to the connected schools on a Saturday. In this study, we got the results as follows: First, we prepared the curriculum environments which can accept the learning-demands of students in a small scale school located in a rural community. To do so, we publicized the curriculum of a vocational high school connected to that of a general high school, made questions, and organized the committee of students, parents and teachers and so on. Second, we organized and implemented the connected curriculum so that a small number of students could learn the subjects they demands. So, a small number of the vocational high school students could have learned the 'Math I' and 'English Conversation' which were not allowed in their school. And also, a small number of the general high school students who hope to have an occupation after graduation could have learned 'Web Design' subject. Third, we examined the problems and presented the solving methods according to organizing and implementing the connected curriculum. So we could have served as an aid on building up the foundation of the generation of the elective-centered curriculum.
