The purpose of this study is to express visual and functional diversity through modifiable design, and to suggest a methodological model. With this view, this study was aimed to departmentalize the case of knitwear in modifiable design of clothes and propose the possibility of variable knit fashion through make the most of knit's characteristics. Four wearable physical clothes using the most of flexible knits' characteristics were made for this study based on the modifiable design on the expressive tendency and analysis of plasticity. The following results were obtained. First, as modifiable knit design can create effects of several dresses in visual aspect and functional aspect, so it has practicality and functionality. Because modifiable clothes required wearer's participation, this have amusement that give enjoyment and freshness to wearer. Second, in mode of wearing, flexibility of knit is suitable character to open & close and change of wearing position. In manipulation, a prearranged plan for line of clothes and good choice of subsidiary materials are important. Third, the characteristics of knits allow using and mixing with different pattern and materials on the two sides of the same cloths except for the some of the parts. Moreover, there is no unraveled thread on the part of knits margin against woven, so it has the broad applicable range for the changeable design. Finally, the form and function, a prearranged plan for modifiable design of clothes have all contributed in creating new structure and patterns in design.

The modifiable design of clothes is significant in that a single garment can be presented in various ways and can be modified by user adjustments as well different kinds of figurative beauty can be expressed through the garment. This study departmentalized the case of knitwear in the modifiable design of clothes to propose a possibility of a variable knit fashion that makes the most of the knit characteristics. This study investigated precedent research, arranged general terms, created fundamental notions, found the background of the advent, and located specific characters in the modifiable design as well as arranged a concept, type, structure, and traits for the knit. The following results were obtained through this study. First, the modifiable design of the clothes can express the change of the silhouette and the change of the item itself or a change in the item according to the change in the mode of wearing, manipulation, and technology. Second, the results show that modifiable knit designs by open & close are mostly used according to manipulation and have no existence in this study according to the technology. Third, there was a noticeable appearance of a modifiable knit design from 2002 to 2004. However, it was increased again in 2009 after a steady decrease in 2005 and 2008. Finally, it can create effects in several dresses in the visual aspect and functional aspect.

This paper deals with the personal computer based design for the sequential machines. Most part of sequential machine design have been implemented by using general purpose microprocessors in order to obtain the specific unctions required for their system. But, they have some difficulties in design stages. Knowledge of systems design method and high technology are basically applied to all the design stages.. Therefore ready made microcomputer system for personal use, personal computer, can be transformed to sequential machines by using the corresponding softwares and built-in personal computer input/output ports. Following the state transition diagram or table, we can obtain the ROM type of sequential machines directly and need not to design input/output interface except actuators and samplers because of capability of personal computer. Our main purpose of this design method are quick, flexible, reliable, modifiable circuit design of the sequential machines. In this paper, we use APPLE-II plus personal computer as target machine.

Objectives: To estimate the proportion of liver cancer cases and deaths due to infection with hepatitis B virus (HBV), hepatitis C virus (HCV), aflatoxin exposure, alcohol drinking and smoking in China in 2005. Study design: Systemic assessment of the burden of five modifiable risk factors on the occurrence of liver cancer in China using the population attributable fraction. Methods: We estimated the population attributable fraction of liver cancer caused by five modifiable risk factors using the prevalence data around 1990 and data on relative risks from meta-analyses, and large-scale observational studies. Liver cancer mortality data were from the 3rd National Death Causes Survey, and data on liver cancer incidence were estimated from the mortality data from cancer registries in China and a mortality/incidence ratio calculated. Results: We estimated that HBV infection was responsible for 65.9% of liver cancer deaths in men and 58.4% in women, while HCV was responsible for 27.3% and 28.6% respectively. The fraction of liver cancer deaths attributable to aflatoxin was estimated to be 25.0% for both men and women. Alcohol drinking was responsible for 23.4% of liver cancer deaths in men and 2.2% in women. Smoking was responsible for 18.7% and 1.0%. Overall, 86% of liver cancer mortality and incidence (88% in men and 78% in women) was attributable to these five modifiable risk factors. Conclusions: HBV, HCV, aflatoxin, alcohol drinking and tobacco smoking were responsible for 86% of liver cancer mortality and incidence in China in 2005. Our findings provide useful data for developing guidelines for liver cancer prevention and control in China and other developing countries.

BACKGROUND/OBJECTIVES: A number of studies examined secular trends in blood lipid profiles using time series data of national surveys whereas few studies investigated individual-level factors contributing to such trends. The present study aimed to examine secular trends in dietary and modifiable factors and hyper-LDL-cholesterolemia (HC) prevalence and evaluate their associations using time series data of nationwide surveys. SUBJECTS/METHODS: The study included 41,073 Korean adults aged ≥ 30 years from the 2005, 2007-2009, 2010-2012, 2013-2015, and 2016 Korea National Health and Nutrition Examination Surveys. Stepwise logistic regression analysis was performed to select significant factors associated with HC, which was defined as serum LDL cholesterol levels ≥130 mg/dL. RESULTS: The following factors showed a positive association with HC (P < 0.05): for men having higher body mass index (BMI), being married, having an office job, and consuming higher dairy and vegetable oil products; for women having higher age or BMI, having no job or a non-office job, not in a low-income household, and consuming higher dairy products. In the given model, the 2016 survey data showed that a 2 kg/㎡ reduction in BMI of obese persons resulted in a decreased HC prevalence from 30.8% to 29.3% among men and from 33.6% to 32.5% among women. CONCLUSIONS: Based on these findings, it is suggested that primary prevention programs should advocate having proper BMI for Korean adults with a high-risk of HC. However, whether discouraging consumption of dairy and vegetable oil products can reduce HC prevalence warrants further studies with a prospective longitudinal design.

This study is including the independent project, "building children's library of the town" that is conducted by a local resident. The study object is the contents of the "design workshop for library planning" and the general process during one year since the opening. This study is delivering "information of children's library" through the work-shop and is conducting the role of a professional space planner by measuring the blueprint. Thus, the study could be conducted with synthetic viewpoint on each library. The followings are the results from the study. First, there were various space operations and a variety of programs in the case library that is independently managed. This is directing to "the constructive and active space usage" by the users and finally results in positive circulation. Secondly, there is a change through the process of execution and operation in the library construction plan. There are needs for the flexible space expansion and adjustment, modifiable furniture layout and design and various keeping areas because there is on-going tendency of corresponding space change. The third, the author could draw more practicable consideration points for space planning by looking at the trend of space change in Transactionist viewpoint. Thus, this study is very meaningful in terms of planning of sustainable public areas.

A method, termed as the substructural sensitivity synthesis method, which utilizes the computational merits of the component mode synthesis technique is proposed to calculate design sensitivity of modal parameters of substructurally combined structures. In this method, the sensitivity analysis is combined with component mode synthesis thchnique. thus the degrees of freedom of a combined structure can be dramatically reduced. Free-interface mode method including the residual attachment modes among the component mode synthesis methods is used to calculate the modal sensitivity of the combined structure. For the design sensitivities of modal properties of structure, the Nelson's method, which is exact solving method is used. It is shown that the modal sensitivities of the entire structure can be obtained by synthesizing the substructural modal data, and the sensitivities of the modal data about the design variables of modifiable substructure. Using the proposed method, the final degrees of freedom of entire structure can be remarkably reduced to calculate the modal parameter sensitivities. With a structure composed of beams and plates, as an example, the sensitivities of the eigenvalues and eigenvectors obtained by this proposed method were compared with the exact solutions in terms of accuracy.

Relaxed Static Stability(RSS) concept has been applied to improve aerodynamic performance of modern version supersonic jet fighter aircraft. Therefore, the flight control systems are necessary to stabilizes the unstable aircraft and provides adequate handling qualities. The initial production flight control system are verified by flight test and it's always an elements of danger because of flight-critical nature of control law function and design error due to model base design method. These critical issues impact to flight safety, and it could be lead to a loss of aircraft and pilot's life. Therefore, development of an easily modifiable RFCS(Research Flight Control System) capable of reverting to a PFCS(Primary Flight Control System) of reliable control law must be developed to guarantee the flight safety. This paper addresses the concept of SSWM(Software Switching Mechanism) using the fader logic such as TFS(Transient Free Switch) based on T-50 flight control law. The result of the analysis based on non-real time simulation in-house software using SSWM reveals that the flight control system are switching between two computers without any problem.
