Changes in eating culture patterns has been observed among modern Koreans from seeking out traditional types of eating out restaurant to the modern, luxurious, and hybrid food. This study aimed to investigate the patterns of eating out and preference of food in Pusan National University (PNU) area, representing typical Patterns of eating out in Pusan. Data revealed that the most popular places in which the subjects visited were Korean traditional restaurants and snack bars. The names of the places were in trendy style of Korean connotation, with Intention to appeal to the new generation. The interviewee reported that decision making on choice of plates were made by taste, price, and service in that order. The frequency of eating out was once In two or three days, Korean traditional restaurants, noodle shops, and restaurants of offering fusion food being the Place of choice. Preferred reasons for the PNU area were reported to be low price, followed by variety of food offered and geographical accessibility to the places. Most of the interviewees in the area were satisfied with the taste of food and service quality. A list of food they were willing to introduce to oversea foreigners included raw fish, Dongrae Pajon, Pulgoki, Kimchi and dog soup in that sequence. The results of survey indicator that changes in the eating out environment in Pusan were improvement of service quality, development of new recipes, improvement of hygiene standards and development of area-specific food. The results may also act as a guide in changing the eating out environment and developing tourism in Pusan.

Currently a KTX train of 20-car formation is 388m long and carries 931 passengers including one captain and three crews which is quite a few to cover the lengthy service area and many customers. On the other hand, if a passenger wants to talk to an attendant, he has to wait for an attendant passing by his/her seat or walk to an intercom which is placed at every other car. Any of these choices is inconvenient. So, in this paper, we presented a system design for developing an audio/visual communication system for a passenger and an attendant. The system was analyzed and designed according to the Object-Oriented methodology with UML (Unified Modeling Language). Based on a problem statement, a Use-case Diagram, Sequence Diagrams, Class Diagram, State Charts, collaboration Diagram were generated. The design will be used in system implementation to a HEMU-400X test train and to be tested.

This study investigated the effect of young children's interaction with a teacher and computer environments on their development of representational competence cf replay, the children's ability to construct and reconstruct actions. A pretest-posttest design with one experimental group and one control group was used; quantitative analyses, including interview assessments and coded observations of children's work in the context of educational interventions were supplemented by qualitative analyses of this work. Thirty-nine children (2-5 years of age) were randomly assigned to either an experimental or control group. The educational intervention provided to the experimental group involved a sequence of twenty sessions incorporating a series of three computer environments. A teaching strategy, based on Vygotsky's Zone of Proximal Development (ZPD) and Sigel's distancing theory, was used to mediate children's interaction with these computer environments. Results indicated that children's representational competence kept developing and reached a higher stage and the educational intervention fostered the development of representational competence, with strong evidence of near transfer but no evidence of far transfer. These results suggest that representational competence is a teachable concept and that a complex mediating structure allows children to reconstruct their previous experiences and apply them to problem situations.

The typical Critical Path Method (CPM) leaves it to the construction managers to overcome two problems in developing networks. First, the construction manager needs to prepare information on the type of activities and their precedence relations in order to develop a network schedule. Second, he or she can include space information into the network schedule such as the locations where the activities take place, only with difficulty. These two problems make it difficult for an inexperienced person to create a network. The purpose of this paper is to provide construction managers with set equations of creating a network schedule for multiunit projects. A space-resource combined network creation are presented in this paper, which includes equations for generating a list of required activities, their precedence relations, and information on their location. Information on the space (location) and the resource is the required data for this method. Based on this information, this method divides a project into a number of activities so that each activity contains the information on the location where the activity takes place and the principal resource required for that activity. Precedence relations are then obtained from the sequence of space and resource. This method has the potential to reduce human efforts in scheduling activities.

In the case of developing the real-time system using object-oriented method, k the problem of the timing constraints is certainly considered. we propose the method of modeling the object-oriented real-time system using the OMT methodology and the SDL. And we also present the predictable time table that reflects the constraints of real-time system into dynamic model of OMTs and the predicatable time formula of the sequence, repeat, and parallel routine. The proposed method is applied to the estimate of the maximum process time of the ATMs(Automatic teller machines) and is used to specifying the functional specification for the user interface of the ATMs using the SDL syntax and the object interaction graph.

Unlike RNA interference, whose usage is limited to eukaryotic cells, Peptide Nucleic Acid (PNA) technique is applicable to both eukaryotic and prokaryotic cells. PNA has been proven to be an effective agent for blocking gene expressions and has several advantages over other antisense techniques. Here we developed a parallel computing software that provides the ideal sequences to design PNA oligos to prevent any off-target effects. We applied a new approach in our location-finding algorithm that finds a target gene from the whole genome sequence. Message Passing Interface (MPI) was used to perform parallel computing in order to reduce the calculation time. The software will help biologists design more accurate and effective antisense PNA by minimizing the chance of off-target effects.

This paper describes a research work of developing an automated progressive design system for manufacturing the product with multi processes such as piercing, bending, and deep drawing. An approach to the system for progressive working is based on the knowledge-based rules. Knowledge for the system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system consists of three main modules, which are shape treatment, strip layout, and die layout modules. Based on knowledge-based rules, the system is designed considering several factors, such as material and thickness of a product, piercing, bending and deep drawing sequence, and the complexities of the blank geometry and punch profiles. It generates the strip layout drawing for an automobile product. Die design for each process is carried out through the die layout module from the results of the strip layout module. Results obtained using the modules enable the designers for manufacturing products with multi processes to be more efficient in this field.

Tomato yellow leaf curl virus (TYLCV), a member of the genus Begomovirus, is responsible for one of the most devastating viral diseases in tomato-growing countries and is becoming a serious problem in many subtropical and tropical countries. The climate in Korea is getting warmer and developing subtropical features in response to global warming. These changes are being accompanied by TYLCV, which is now becoming a large problem in the Korean tomato industry. The most effective way to reduce damage caused by TYLCV is to breed resistant varieties of tomatoes. To accomplish this, it is necessary to establish a simple inoculation technique for the efficient evaluation of resistance to TYLCV. Here, we present the rolling circle amplification (RCA) method, which employs a bacteriophage using phi-29 DNA polymerase for construction of infectious TYLCV clones. The RCA method is simple, does not require sequence information for cloning, and is less expensive and time consuming than conventional PCR based-methods. Furthermore, RCA-based construction of an infectious clone can be very useful to other emerging and unknown geminiviruses in Korea.

A new murine TGF-$\beta$ family member, myostatin(growth/differentiation factor-8) is expressed specifically in developing and adult skeletal muscle and may be a negative regulator of skeletal muscle development. This study aims at characterization and identification of genomic organization of chicken myostatin gene. In thi study, we identified the genomic organization and sequence of chicken myostatin gene. Results of RT-PCR and Northern blots from various tissues showed different mRNA expression levels in developmental stages of chick embryos and demonstrated strong expression of myostatin mRNA in skeletal muscle. These facts suggest that chicken myostatin gene would play an important role not only in skeletal muscle cell but also in other tissues.
