In this paper, I propose the effects of food therapy on subjects' health and happiness. The result has come out that food therapy enhances subjects' multi-dimensional health(medical, functional, self-evaluative) and their happiness. The participants were 230 adults over 30 years old living in Seoul and Gyeonggi district. To examine the effect of food therapy, the study sampled 220 questionnaire out of 230. By the non-equivalent control group design, the health levels were measured in three concepts: medical dimension, functional dimension and self-evaluative dimension. The results are as follows: First, participants who had taken food therapy for 3 months have been enhanced in their subjective and functional health level. Their subjective health enhanced from $2.80{\pm}.44$ to $4.07{\pm}.27$ (p=.000). And their functional health enhanced from $.92{\pm}.07$ to $.94{\pm}.07$(p=.035). Second, participants' happiness has enhanced significantly. Cognitive happiness enhanced from $3.39{\pm}.50$ to $3.84{\pm}.44$(p=.000). And emotional happiness enhanced from $2.76{\pm}.44$ to $3.07{\pm}.34$(p=.000). With this results, in case that people apply food therapy based on Yaksun, they are able to expect their enhancement of health level and happiness. Therefore study shows that Food therapy helps people to pursue their health and happiness improvement and suggest valuable information of a way to enhance quality of life.

The configuration design of a mechanical product can be efficiently performed when it is based on the functional modeling. There are methodologies, which decompose function from the abstract level to the concrete level and match the functions to physical parts. But it is difficult to carry out an innovative design when the function is matched only to a pre-detined part. This paper describes the configuration design process of a mechanical product with a design expert system, which uses function taxonomy and TRIZ theory. The expert system can propose a functional modeling of a new part. which is not in the existing parts list. The abstraction levels of design knowledge are introduced, which describe the operation of mechanical product in the levels of abstraction. This is the theoretical background of using knowledge of function and TRIZ for configuration design. The expert system is adequate to control this design knowledge. which expresses knowledge of functional modeling, mapping rules between functions and parts, selection of parts, and TRIZ theory. The hierarchy of functions and machine parts are properly expressed by classes and objects in the expert system. A design expert system has been implemented for the configuration design of a train bogie, and a new brake system of the bogie is introduced with the aid of TRIZ's 30 function groups.

In this paper, we present a SystemC model of a 32-Bit RISC core wi)ich is based on the ARMTTDMI architecture. The RISC core model was first modeled in C for architecture verification and then refined down to a level that allows concurrent behavior lot hardware timing using the SystcmC class library. It was driven in timed functional level that uses handshake protocol. It was compiled using standard C++ compiler. The functional simulation result was verified by comparing the contents of memory, the result of execution with the result from the ARMulator of ADS(Arm Developer Suite).

Requirements engineering is an important phase in a system's life cycle. It is important to perform it correctly. The increasing complexity of systems makes requirements engineering activities more difficult. Non-functional requirements are drivers to emerge how much emergent system properties to aim for success. All functional requirements may be satifsfied, but if the level of desired non-functional requirements are overlooked, the system development will fail. There is growing awareness of the importance of defining non-functional requirements early in the process among the requirements engineering (RE) community. This paper propses a SysML based approach for non-functional requirements to identify and specify very early in the process or requirements engineering.

Amongst various analytic methods of internal structure of city, the factor analysis method which uses O-D matrix data has some merits and characteristics compared to other methods. 1) It is possible to find one certain interaction and flow pattern between traffic zones with in a city through reanalyzing O-D data which is too complex to grasp specific meaning or pattern of flow systems. 2) It can be easily visualized the traffic flow pattern by using adequate graphic techniques, and also can clarify the functional areas whose interaction linkages are significantly strong enough between each other. In this study, the taxi traffic O-D data between 42 traffic zones in Kwang-ju city was reanalyzied by varimax rotated factor analysis methods. As a result, four factors that have significant level factor loading (over 0.5 ) and factor score (over 1.0) were sorted out. so to speak four different functional areas were clarified in Kwang-ju city, of the West, the East, the south, and the North functional areas whose interaction linkages are significantly strong enough between each other. In the study, the taxi traffic O-D data between 42 traffic zones in Kwang-ju city was reanalyzied by varimax rotated factor analysis methods. As a result, four factors that have significant level factor loading (over 0.5) and factor score 9over 1.0) were sorted out. so to speak four different functional areas were clarified in Kwang-ju city, of the West, the East, the South, and the North functional area, then these four functional areas are almost coincided with citizen's general conception of community division and administrative district. Accordingly the factor analysis methods using traffic data seems to proved to be very accurate and useful analytic instruments for analyzing flow pattern and clarifying functional areas of city, and believed to provide basic informations and criteria for practical urban land use planning and transportation planning.

Purpose: The purpose of this study was to identify the patterns of activities of daily living (ADL) functional status and to examine the relationships between sense of coherence(SOC), depression, and uncertainty in gynecologic cancer patients who were receiving chemotherapy. Method: A prospective, longitudinal design with repeated measures was utilized. Women reported depression, SOC, and uncertainty at the beginning of the first cycle of chemotherapy, and they recorded ADL functional status everyday for two consecutive treatment cycles. the The instruments used were the Karnofsky Performance Status Index, Orientation to Life Questionnaire, Beck Depression Inventory, and Mishel Uncertainty in Illness Scale-Adult Form. Result: Data from 42 women showed that the ADL functional status during the second cycle was better than that of the first cycle with significant improvement each week. However, it did not completely recover to the baseline level even three weeks after the treatment ended in both cycles. SOC was correlated with depression(r=-.64, p<.001) and uncertainty(r=-.62, p<.001). Uncertainty was related to depression (r=.66, p<.001) and to functional status during the second cycle(r=-.45, p<.05), while the scores of the functional status during the two cycles were not related. Conclusion: Changing patterns and level of functional status during the treatment phase would be useful information for cancer patients to prepare coping strategies for positive health outcomes.

Purpose: The purpose of this study was to identify the factors that influence the functional status of patients with heart failure. Method: A descriptive, correlational study design was used. The participants in this study were 260 patients with heart failure who were admitted at Y University and U University in Seoul, Korea. Between September 2005 and December 2005 data was collected by an interview using a questionnaire and from medical records. The Functional status was measured with KASI. Physical factors (dyspnea, ankle edema, chest pain, fatigue, and sleep dysfunction), psychological factors (anxiety and depression), and situational factors (self-management compliance and family support) were examined. Result: In general, the functional status, anxiety, depression, self-management compliance, and family support was relatively not good. The level of fatigue was highest and the level of ankle edema was lowest for physical symptom experiences. In regression analysis, functional status was significantly influenced by dyspnea(23%), age(13%), monthly income(7%), fatigue(3%), ankle edema(2%), depression(1%), and length of stay in the hospital(1%). These factors explained 50% of the variables in the functional status. Conclusion: These results suggest that psycho-physiological symptoms management should be a focus to improve the functional status in patients with heart failure.

Multi-functional weirs has been installed in four rivers are hydraulic structures across the river. The structures were divided into movable and fixed weirs. Hence, riverbed-level variation and sediment transport can be varied due to water gate operation. In this study, the long-term riverbed-level variation of Geum river basin due to water gate operation of multi-functional weirs was studied. Result of this study shows that the variation of thalweg elevation was greater than the variation of annual average riverbed elevation due to multi-functional weirs construction and water gate operation. Maximum riverbed degradation of thalweg elevation that occurred was 2.79m and riverbed aggradation was 1.90m. Maximum riverbed degradation of the annual average riverbed elevation that occurred was 2.16m and riverbed aggradation was 1.24m. Analysis result of flood stage by the variation of riverbed-level shows that flood stages were increased in majorities area. The maximum increase in the value of flood stage was 2.23m. For this reason, flood stages can be greater than the freeboard of the levees. Therefore, we should consider the water gate operation of multi-functional weirs when planning and managing sediment in the river. We are expecting to use the result of this study in river planning for river management and selecting the river regime.
