Clothing for hospitalized patients is very important because they wear it while they suffer from various kinds of pain and treatments. Therefore, the clothing for patients has to be comfortable and functional as well as well designed. Also correct sizes, suitable materials and convenient fastening devices are features to be considered for proper patient's clothing. However the currently used patient's clothing is provided without sufficient considerations for patient's needs, and is more concerned with price competitiveness. The purpose of this survey was to find out which design and functional features of patient's clothing are favored by patients, doctors and nurses. The results will be useful to develop improved patient's clothing. Based on the results, the following suggestions for improved patient's clothing are made. 1. Gender differentiation and a greater variety of size codes are required for better fit. 2. Depending on various treatments, different functional design features have to be applied. 3. Aesthetic needs should be satisfied for the psychological comfort of patients. 4. Materials should be selected considering required physical properties such as washing duration, dimensional stability and contaminant prevention.

This clinical report presents conservative and esthetic ceramic veneer treatments without tooth reduction. Patients' benefit from avoiding invasive procedure is discussed in terms of biologic price. The margin is placed not only at the cervical area, but also at any place on the tooth where additive volume increase is required. Techniques to camouflage the margin is described where contact lens effect is difficult to achieve. Proper case selection would be imperative to avoid periodontally hazardous restoration.

A FCM with locational price and regional information between locations are proposed in this paper. Any point in a networked system has its own values indicating the physical characteristics of that networked system and regional information at the same time. The similarity measure used for FCM in this paper is defined through the system-wide characteristic values at each point. To avoid the grouping of geometrically distant locations with similar measures, the locational information are properly considered and incorporated in the proposed similarity measure. We have verified that the proposed measure has produced proper classification of a networked system, followed by an example of a networked electricity system.

Consumers have more choices for apparel products as e-shopping grows. This study examines the importance of apparel product attributes and classifies online apparel buyers into groups based on product attribute evaluation in various choice sets. For the empirical research, the online survey was conducted and Latent Gold Choice 4.0 was used for the choice-based conjoint analysis. Five consumer segments are found based on the choice selection of product attributes. The importance of product attributes (online shopping mall, brand, price, and style) and the preference of each product attribute level were different across segments. This research improves the knowledge of the purchasing behavior of online apparel buyers and provides proper attribute combinations of apparel e-shopping for each consumer segment.

Polystyrene foam is easily melted and vapoured by heat, has a proper quality in the pattern manufacturing and has a low price. The objective of this study is to develop a rapid prototyping method fur polystyrene foam pattern manufacuring to use the eliminative pattern casting (EPC). Applying fur the rapid prototyping concept reversely, the unnecessary part of section is vapored away by heat source of laser beam. In order to examine the applicability between laser beam process and polystyrene foam material, the basic experiments such as hole, line, plane and contour process are carried out. With these results, various three-dimensional shape patterns are made and this rapid prototyping tool for polystyrene foam manufacturing.

To get the items that a buyer wants in Internet auction. he must search for the items through several auction sites. When the bidding starts, he(the buyer) needs to connect to these auction sites frequently so that he can monitor the bid stats and re-bid. A reserve-price auction reduces the number of connections, but this limits the user's bidding strategy. Another problem is equity between the buyer and the seller. Both the buyer and the seller should profit together within proper limits. In this paper, we propose an auction agent system using a collaborative mobile agent and a brokering mechanism called MoCAAS (Mobile Collaborative Auction Agent System), which mediates between the buyer and the seller and executes bidding asynchronously and autonomously. This reduces connection costs. offers more intelligent bidding and solves the equity problem.

Direct-drive SCARA-type industrial robots are increasingly used in the assembly process of small mechanical parts as well as electronic components, which uses direct-drive (DD) motors instead of reduction gear-type conventional motors for the actuators of manipulator arms. There are many advantages in using DD motors for robots, such as no backlash, low friction, high mechanical stiffness capability for fast and precise arm control, and high repeatability of positioning. However, there exist a number of difficulties which must be overcome to ensure proper construction and operation; increasing effects of load veriation and nonlinear and coupling dynamics, severe vibration caused by resonance of the manipulator components and low mechanical damping, etc. In order to handle these difficulties, lots of efforts have been made such as reduction of the arm inertia and elimination of the resonance, Performance evaluation of a recently developed, domestic DD robot shows that it works excellently compared with conventional robots. It, however, requires proved reliability and price competitiveness against its foreign counterparts.

There are an electronic and a manual type in Bidet. The electronic bidet has some advantages. it supplies multiple functions and is up easily. However, it has frequent defects and a high price. The manual bidet is not need to supply electric and is cheaper than the electronic type. However, it is needed to supply hot water and is hard to set up. In order to solve these defects, this study designed a bidet heating unit using an electric instantaneous water heating method. To get a proper heating elements, experiments were performed about a Ni-Cr heater and a film heater.

Optimizing morphology of the front surface with three dimensional structures (3D) in solar cell is essential element for not only effectivelight harvesting but also carrier collection and separation without the cost burden in process. We designed a three-dimensionally ordered front surface with wet chemical etching. Wet chemical etching is a proper way to have three dimensional structures. The method efficiently transmits the incident light at the front surface to a Si absorber and has competitive price in manufacturing when comparing with reactive ion etching (RIE) to have three dimensional structures. This indicates that optimized front surface with three dimensional structures by wet chemical etching will bring effective light management in solar cells.

Historically, the name and scopes of Agricultural Engineering have changed considerably affected by many factors including global trend of Agricultural Engineering. There were times when this education program became unpopular but then again regained in the aftermath of economic crises. The afterward national policy has given big opportunity to resources based developments. Even though agriculture has shown its capability in maintaining local community to support their lives during the time of crises, the global markets have become the real threats. The challenge of Indonesian Agricultural Engineers now is how to produce agricultural commodities in any kind of forms but cheaper than the international price. Agricultural Engineering Education has to find a proper role of contribution to solve these problems. And, the education system of Agricultural Engineering itself has to be upgraded to some extend to anticipate changes of the global trends.
