Dan(緞) is satin damask. It was a newly popularized fabrics in the Joseon Period and is one of main traditional fabrics at present. The purpose of this study is to suggest a theoretical basis to name Dan(緞) remains properly by comparing and analyzing the name, pattern, usage, feature, length and width, value of Dan(緞) recorded on documents made at the end of the Joseon Period. The results of this study are as follows. 1. The kinds of Dan(緞) recorded on documents made at the end of the Joseon Period are various. Among fabrics named Dan(緞), were not only silk fabrics but also cotton fabrics, woolen fabrics, mixture fabrics with silk and cotton, and mixture fabrics with cotton and wool. 2. Some newly revealed patterns in the case of Dan(緞) are as follows. The shape of Byeolmun(別紋) is assumed to have originated from that of character symbolizing the Royal Family and developed into a variety of circular ones of dragon, phoenix, flower, or character. O-ho-ro-mun(五葫蘆紋) was five-gourd-shaped patterns that form a circle, turning their narrow mouth to the center, and vines between each two gourds. 3. When considering the usages of Dan(緞), Dan(緞) was used for various detailed usages according to their kinds. But it was't mostly used for underwear. 4. Features have been examined are Godan(庫緞), Mobondan(模本緞), Handan(漢緞), Daedan(大緞), Yangdan(洋緞), Waedan(倭緞), and Geumdan(錦緞). 5. The length and the width of 1 Pil(疋) silk fabrics are various. It is normal for the width being different, but for 1 Pil(疋)'s length being different is very unusual. The width of Dan (緞) was about 47-76.20cm, it was wider than Ju(紬), Cho, Gyeon(絹), Sa(紗), Ra(羅) and Reung(綾). 6. As for the value of each fabric per $10,000cm^2$, Dan(緞) was the most valuable silks at that time. Among them the most valuable Dan(緞) was Udan(羽緞).

For two input-protection schemes suitable for RF ICs utilizing the thyristor and diode protection devices, which can be fabricated in standard CMOS processes, we attempt an in-depth comparison on HBM ESD robustness in terms of lattice heating inside protection devices and peak voltages developed across gate oxides in input buffers, based on DC, mixed-mode transient, and AC analyses utilizing a 2-dimensional device simulator. For this purpose, we construct an equivalent circuit for an input HBM test environment of a CMOS chip equipped with the input ESD protection circuits, which allows mixed-mode transient simulations for various HBM test modes. By executing mixed-mode simulations including up to six active protection devices in a circuit, we attempt a detailed analysis on the problems, which can occur in real tests. In the procedure, we suggest to a recipe to ease the bipolar trigger in the protection devices and figure out that oxide failure in internal circuits is determined by the junction breakdown voltage of the NMOS structure residing in the protection devices. We explain the characteristic differences of two protection schemes as an input ESD protection circuit for RF ICs, and suggest valuable guidelines relating design of the protection devices and circuits.

In case of current South Korea, the rapid graying is in the progress. Because of it, the increase of elders who live alone causes variety of social, economic and national problems. Especially in the modern city, the health care, safety and maintenance of pleasant and joyful life of elders who live alone are being a big social issue. Even though practical services have been tried at the whole of government approach, the detailed alternatives are insufficient to improve the daily life support and service to approach the information. This research suggests the "ELA Service Model" which actively improves the easy access to information and corresponds to condition and circumstance of elders for providing the ICT-base Elderly Living alone care service. It is a step self-life support service based on fundamental desire of elders which resolves the problem and contributes to establish the active and balanced policy to the elderly.

This paper preliminarily investigates the effectiveness of various control systems, such as passive, active, semiactive and hybrid control, for seismic protection of cable-stayed bridges by examining the ASCE first generation benchmark problem for a cable-stayed bridge. This benchm.0.00000ark problem considers the cable-stayed bridge that is scheduled for completion in Missouri, USA In 2003. Seismic considerations were strongly considered in the design of this bridge due to location of the bridge and its critical role as a principal crossing of the Mississippi River. Based on detailed drawings of this cable-stayed bridge, a three-dimensional linearized evaluation model has been developed to represent the complex behavior of the bridge. A set of eighteen evaluation criteria has been developed to evaluate the capability of each control system. In this study, four passive control systems, one active control system, two semiactive control systems and three hybrid control systems are considered. Numerical simulation results show that all the control systems are effective in reducing the responses of the benchmark cable-stayed bridge under the historical earthquakes. To get good performance, however, the passive control systems need quite large control forces compared to other control systems. The simulation results also demonstrate that the passive, semiactive and hybrid control systems are robust to the stiffness uncertainty of the structure. Therefore, the semiactive and hybrid control systems are more appropriate in real applications for full-scale civil infrastructures.

The guidelines for the district unit planning(DUP) of detached houses in the area of Misagangbyeon-City (MISA) do not consider the characteristics of the region. Therefore, this study was conducted to analyze the relationship between the blocks and parking lots of the detached houses area. The research results can be summarized as follows: 1) Detailed design guidelines are provided for apartment homes in MISA, but not for detached houses. 2) Apartment home and multi-family house parking lot equivaluation calculations exist in the DUP guidelines, however there are no regulations related to detached houses and the problem of parking for these residents is worsening which causes tension. 3) The DUP guidelines stipulate that the outer wall material of multi-family houses must be glass, however this is a dangerous material for use on the first floor, because cars that park close to this wall. 4) There is a significant risk to elementary and kindergarten students who must walk along the road in the inner blocks where cars are driving quickly. 5) There are a number of issues involved when planning parking lots without considering the characteristics of the area. The local government uses the traditional parking lot codes without considering the current regional characteristics, whereas the number of cars has dramatically increased. 6) The pedestrian mall is not currently being used for pedestrians, because it is full of parked cars due to the lack of parking space.

We are seeing a shift of the focus of information service from system-centered(data-centered or intermediary-centered) a n.0, pproach to user-centered a n.0, pproach. Sense-making theory is one of the user- centered a n.0, pproaches. This study focused on user-centered information service paradigm concepts of Dervin's sense-making theory and interpreting sense-making theory in the practical context of library services. The sense-making theory is basically a cognitive a n.0, pproach to information-seeking, in that it recognizes information as something that involves internal cognitive processes. The user of information becomes the focus in this sense-making model. The sense-making theory sees information as subjective, situational, and cognitive. It focuses on understanding information within specific contexts and on understanding how information needs develop and how they are satisfied. It regards the user not as a passive receive of external information but as the center in a active, ongoing process of change. It related to the information needs of users. Dervin's method for studying information needs employs the 'situation-gap-use' metaphor. All information needs stem from a discontinuity or 'gap! in one's knowledge. Dervin believes that information needs can be addressed by understanding the process that each individual goes through in experiencing a gap, in trying to resolve it, and in gaining something (especially new knowledge) from the experience. Sense-making is a process; 'sense' is the product of this process. Sense includes 'knowledge'. However, it includes a host of other subjective factors that reflect an individual's interpretations of a situation including intuitions, opinions, hunches, effective responses, evaluations, questions, etc. For several reasons, however, difficulties are encountered if one attempts a more substantial assessment of the theory. First, it has not yet crystallized into a well-defined theory. Secondly, though the theory has aroused general interest, e.g. within LIS, detailed discussion of its strong and weak points is still lacking. A third source of difficulty is that the basic assumptions of the theory have been explicated metaphorically. If sense-making theory is to be really useful, it needs to be interpreted for library settings. But we have found no attempt to construct an information service based on the theory. Because the research tradition is still relatively young, there are many unanswered questions connected, e.g. with the design of information systems. In any case, e.g. intermediary access systems would be more efficient and effective it their planning could be founded on the user-centered a n.0, pproach.

Recently, existing river improvement methods for flood control purpose have changed into nature friendly river improvement methods and the efforts to improve the river environment including river restoration have been made, and close-to-nature river improvement and nature friendly river restoration are actively conducted all over the country. In the present situation where various revetment methods are used after the introduction of the concept of close-to-nature river improvement, the environmental characteristics of rivers need to be considered to apply more suitable revetment methods. Therefore, as a precedent study for the development of revetment evaluation techniques and methods for close-to-nature river improvement, the present study suggested evaluation techniques using detailed survey items through field survey. Evaluation items of hydraulic stability consist of mode of streamline, stream bed gradient, flow velocity and tractive force ratio and those of environmental efficiency consist of revetment of vegetation, state of river water, land use of the terrace land on the river, vegetation and materials of the terrace land on the river. Each item was graded with the point 1 through 5. Hydraulic stability and environmental efficiency was evaluated by the points which were averaged in each items. As the result of the application of the proposed evaluation technique, it was found that a number of existing revetments excessively focus on hydraulic stability with little consideration about environmental term. It is expected that the proposed technique in the present study can be used as a base for providing guidelines to construct the design and construction of revetments in the future.
