This research aims to analyze rational decision behavior in different stages of purchasing for consumers buying household appliance goods and deals with differences in socio-demographic features and relevant variables among completely rational, intermediatedly rational, and irrational groups as well as variables differentiating those groups. First, one third of purchasers for Kimchi refrigerators was the rational consumer while a half of purchasers for side-by-side refrigerators and washing machines was. Second, there was no significant differences in satisfactions levels after purchase between rational and irrational groups among purchasers of side-by-side refrigerators but between completely and intermediately rational groups in the case of Kimchi refrigerators. Rational groups of consumers for Tromm washing machines rely on various places for purchase and also show the high level of intention for repurchase. Third, in studies of variables differentiating rationality in purchase behavioral patterns of consumers, rational choices turn out to prevail (1) among purchasers of married, college graduated, employers, and high income in the case of side-by-side refrigerators, (2) among buyers of male, old-aged, college graduated, non-employers, low, income, and hurrying to purchase in the case of Kimchi refrigerators, and (3) among buyers of old-aged, high income, not hurrying to purchase, and visiting numerous stores in the case of Tromm washing machines.

This study was intended to grasp the actual condition of adult women's wearing foundation garments for the Korean adult women in their 20s to 40s. For this purpose, questionnaire research was conducted for 639 adult women in their 20s to 40s living in Seoul and Kyonggi Province. As for the reason for the purchase of foundation garments, It was found that the highest proportion of the responding adult women would buy brassieres when they were needed because the old ones were threadbare, followed by the purchase of brassiere when they caught their eyes in shopping around. As for the reason for the purchase of girdles, the highest proportion of the responding adult women could buy girdles when they were needed because their old ones were wornout, and next when bargain sale began at the department store or the large shopping center. The highest proportion of the responding adult women thought the source of information on foundation garments as the window display, followed by magazine. The adult women in their 30s collected information on foundation garments through the window display when buying brassieres or girdles. As for the product evaluation criteria of foundation garments, the highest proportion of the responding adult women thought highly of the feeling of wear in brassieres and girdles, followed by dimensions in brassieres and bodily correctability in girdles. As for the place of buying brassieres or girdles, the responding adult women showed it to be the department store. followed by the discount store and the well-known agency.

The most tunnel damage such as cracks or leakage which exist in tunnel lining commonly, is caused by the cavities where exist behind the tunnel lining, through the tunnel safety inspections. These cavities were analysed to affect a stability of a running-tunnel seriously. This study is on the development of the controlled low-strength and flowable filling material which is able to apply to the cavity behind the tunnel lining. The major materials of backfilling developed are a crushed sand and a stone-dust which exists as a cake-state and is a by-product obtained in the producting process of aggregate. It is conformed with the design standard to the physical characteristics of backfilling. The backfilling material developed is designed to reduce the fair amount of cement. According to the designed compound ratio, it is carried out the laboratory tests such as a compressive strength and a chemical analyses and is applied to dilapidated old tunnel for an application assessment.

Cementifying fibroma is an odontogenic tumor of periodontal ligament origin, consisting of a proliferation of fibrous tissue that forms cementum. Cemento-ossifying fibroma, cementifying fibroma and ossifying fibroma are difficult to distinguish on clinical and radiographic exmination, and on histopathology. However, when the calcified product is represented by ovoid or curvilinear deposits, the lesion is often referred to as cementifying fibroma. Cementifying fibromas of the jaws are well-circumscribed, generally slow-growing lesions. Although most lesions appear to be limited to the tooth-bearing areas, a few have extended into the angle-ramus area or encroached on the maxillary sinus. Radiographically, the cementifying fibroma could present as a radiolucent, radiopaque or mixed density lesion, depending on the degree of maturity. We have observed two cases of cementifying fibroma occurred in the left maxillary premolar-molar area of 38-year-old woman and 35-year old man. We obtained that two cases were shown the followed results; 1. Clinically, main clinical symptom was facial swelling and pain at palpation 2. Radiographically, well-circumscribed radiolucent lesion and radiolucent lesion with radiopaqu e foci were seen on the left maxillary premolar-molar areas. Loss of lamina dura and root resorption or divergency were also seen. 3. Histopathologically, many cementum-like calcifications were observed in the hypercellular connective tissue.

The ginsenoside content was compared with wild simulated ginseng (Panax ginseng) collected every season at 11 wild simulated ginseng plantations in Korea. As a result, the total saponin of 7 years old wild simulated ginseng showed the highest content of 4.5% in spring sampling wild simulated ginseng, 2.0% in summer sampling wild simulated ginseng, 1.2% in winter sampling wild simulated ginseng and 1.0% in autumn sampling wild simulated ginseng. And also, the total saponin of 10 years old wild simulated ginseng showed the highest content of 3.9% in spring sampling wild simulated ginseng, summer sampling wild simulated ginseng (1.8%), winter sampling wild simulated ginseng (1.6%) and autumn sampling wild simulated ginseng (0.6%). Therefore, the total saponin of spring sampling wild simulated ginseng was about 4.5 - 6.5 times higher than that of autumn sampling wild simulated ginseng regardless of cultivation period.

The exchange of parameterized feature-based CAD models is important for product data sharing among different organizations and automation systems. The role of feature-based modeling is to gonerate the shape of product and capture design intends In a CAD system. A feature is generated by referring to topological entities in a solid. Identifying referenced topological entities of a feature is essential for exchanging feature-based CAD models through a neutral format. If the CAD data contains the modification history in addition to the construction history, a matching mechanism is also required to find the same entity in the new model (post-edit model) corresponding to the entity in the old model (preedit model). This problem is known as the persistent naming problem. There are additional problems arising from the exchange of parameterized feature-based CAD models. Authors have analyzed previous studies with regard to persistent naming and characteristics for the exchange of parameterized feature-based CAD models, and propose a solution to the persistent naming problem. This solution is comprised of two parts: (a) naming of topological entities based on the object spore information (OSI) and secondary name (SN); and (b) name matching under the proposed naming.

This study utilizes a S-O-R model to investigate the effects of apparel product presentations using a 3D avatar model in Internet fashion malls for pleasure(emotional state) and approach behavior. We chose a 3D avatar model to present a fashion product in this study. The model walked for about one minute on stage; subsequently, respondents completed a questionnaire after they viewed it. The questionnaire consists of telepresence, pleasure and approach behavior. Respondents are limited to females 20s and 30s years old who have purchased fashion products in an Internet mall and are highly interested in fashion products. A total of 226 samples were used for the final analysis. Cronbach's alpha, correlation analysis, confirmatory factor analysis, and structural equation modeling were utilized in this study. The results are as follows. First, telepresence has a significant influence on pleasure; subsequently, pleasure influenced consumer approach behavior. Second, telepresence positively influenced the approach behavior (directly and indirectly). This verified the effectiveness of a 3D avatar model using S-O-R. A 3D avatar model can be a strategic alternative in the fiercely competitive Internet shopping sector.

The purpose of this study was to analyze the in vivo amalgam corrosion products qualitatively. 30 molars with large, intact amalgam restorations were selected. All the restorations were more than 5 years old. Twenty of the removed amalgams were embedded in acrylic resin block. The exposed surfaces of fifteen embedded amalgams were polished by amalgam polishing kit, and the rest were observed without polishing. The remaining 10 amalgams were fractured centrally and perpendiculary to the occlusal surface with a wire-cutter. After all specimens were cleaned ultrasonically in distilled water, each surface was examined under S.E.M. and E.D.A.X. (Energy Dispersive Micro X-ray Analyzer) to determine the morphology and chemical nature of the corrosion products. The following results were obtained: 1. The surfaces of the unpolished amalgam restorations were covered with thin amorphous layer of Sn-Ca-P-S complex with numerous cracks. 2. In the conventional amalgams, the major corrosion products were Sn-Cl phases however, tin oxide phases were also observed. 3. Only tin oxide phase was identified in the high copper amalgam, but it was less frequently observed than in the conventional amalgam. 4. It was easier to observe the corrosion product morphology in the fractured surfaces than in the polished ones. The morphologies of the corrosion product crystals looked like a stack of slightly bended plates in the Sn-Cl phases and polyhedra or polygonal prisms in the tin oxide phases.
