As the global uncertainty of manufacturing has increased and the quality problem has become global, the recall has become a fatal risk that determines the durability of the company. In addition, as the convergence of PSS (product-service system) product becomes common due to the development of IT convergence technology, if the function of any part of hardware or software does not operate normally, there will be a problem in the entire function of PSS product. In order to manage the quality of such PSS products in a stable manner, a new approaches is needed to analyze and manage the hardware and software parts at the same time. However, the Fishbone diagram, FTA, and FMEA, which are widely used to interpret the current quality problem, are not suitable for analyzing the quality problem by considering the hardware and software at the same time. In this paper, a quality risk assessment model combining FTA and FMEA based on defect rate to be assessed daily on site to manage quality and fishbone diagram used in group activity to solve defective problem. The proposed FTA-FMEA based risk assessment model considers the system structure characteristics of the defect factors in terms of the relationship between hardware and software, and further recognizes and manages them as risk. In order to evaluate the proposed model, we applied the functions of ITS (intelligent transportation system). It is expected that the proposed model will be more effective in assessing quality risks of PSS products because it evaluates the structural characteristics of products and causes of defects considering hardware and software together.

The population of domestic companion animals is estimated to be about 10 million now. In recent years, the domestic pet market has been launching a wide range of products and services for high quality, smart and well-being. As a result, the market size will increase from 900 billion won in 2012 to 2.3 trillion won in 2016, which has more than doubled in five years. The industry expects to reach 6 trillion won by 2020, expecting 3 trillion won this year. In particular, domestic dogs and cats market is estimated at 275.5 billion won, accounting for 19% of the domestic animal market and 1.425 billion won for the world market. However, despite the growing market for companion animals products, unfortunately the import dependence on related industrial goods is still high and the quality of service is very low. Unlike Europe and the United States, 90% of companion animals are housed in apartments, often causing problems in the health and safety of companions and companions. The purpose of this study is to develop a smart house for companion animals with environmental friendliness and AI function that can be won in competition with products of developed countries. The results of this study are expected to contribute to the creation of a new value - added base for the related industries through the strengthening of the competitiveness of the related SMEs and further the effect of employment increase and import substitution.

This study was conducted to investigate the suitability of frozen oysters as a raw material for the preparation of seafood products by measuring the concentrations of harmful microorganisms and chemicals in thawed flesh. The microbial concentrations in thawed oysters were 2.3-5.0 log CFU/g for viable cell counts, not detected (ND)-1.0 log CFU/g for coliform bacteria, and ND for Escherichia coli and pathogenic bacteria such as Staphylococcus aureus, Salmonella spp., Listeria monocytogenes, Vibrio parahaemolyticus, Enterohemorrhagic Escherichia coli (EHEC), and Clostridium perfringens. In frozen oysters, the heavy metal concentration for viable cell counts was ND-0.030 mg/kg, for lead was ND-0.393 mg/kg, and for cadmium was 0.021-0.597 mg/kg. Benzo(a)pyrene, shellfish poison (paralytic shellfish and diarrhetic shellfish poisons), and radioactivity were not detected in the thawed oysters. These results suggest that frozen oysters can be safely used as a raw material for the preparation of seafood products.

This study was performed to reuse the dyeing wastewater sludge treated by Fenton process through the solidification/stabilization technique. To solidify the dyeing sludge the industrial by-products such as blast furnace slag, fly ash and waste sand with cement were used. The laboratory scale and pilot scale test were conducted at room temperature to make construction brick which has high compressive strength and low leaching of heavy metals. The experimental results showed that blast furnace slag and fly ash could be used instead of cement and the products satisfied the regulation of Korean Standards. The blast furnace slag increased the compressive strength and the optimum ratio of slag/dyeing sludge on dry basis was found 0.4. The solidifying agent of SB series could increase rapidly the compressive strength and the optimum ratio of solidifying agent/sludge on dry basis was 0.26 at which the strength was two times compared with non-added condition. The portion of waste and industrial by-products in matrix was over 80%. From the pilot test the optimum pressure in molding was 100kg/$\textrm{cm}^2$ at which the compressive strength was over 100kg/$\textrm{cm}^2$. And the strength increased continuously to 160kg/$\textrm{cm}^2$ until 120 days curing time due to pozzolanic reaction. When SB-20 as a solidifying agent was used, the unconfined compressive strength of dyeing sludge could be obtained 110kg/$\textrm{cm}^2$ which satisfied the regulation of cement brick in Korea Standard(KS).

Recently the tourism industry has achieved rapid growth and thus stands out as a means for the improvement of international payments and the acquirement of foreign currency. In particular, the hotel and major tourist travel industries have been developed for the inducement of foreign tourists. However, the manu-facturing and sales indust\ulcornerries of tourism folklore haven't developed. The reason is that the endeavor to attract tourists has been more emphasized than the development of tourism folklore which includes chief shopping items and indust-rialization. Tourism folklore plays a great role not only as material evidence of a tourist's visit to a country or region but also as a gift and a souvenir. Also it represents the image and the degree of the industrial development of the nation, so it should be congruent with the nature and the images of the region. Nevertheless, our tourism folklore has been merely mass produced by specific companies that do not represent the region's image and nature in their products. Tourism folklore development can raise the image of Choongnam and serve as a catalyst to induce tourists. Also, it can be an avenue for com$$\mu$ity publicity and industrialization. Thus, this study has examined and analyzed original products made with textiles and metal materials whether can be developed into tourism folklore. Also this study presents the example of developed tourism folklore works in a foreign country. It tries to give the unique symbolic image of Choongnam by developing the original products with Choongnam' s own materials. However, this study has shown that the actual conditions of tourism folklore development in Choongnam are seriously inferior to other industries. The producers are limited. Moreover, the product items are coarse. Many problems are being brought up which should be improved. Hereafter, to develop Choongnam's own tourism folklore, it should be carried out with financial and political support from the government, design development by industrial circles, professional design training and marketing research by the sellers.

In the industry, due to the carbon dioxide gas produced during cement production is increasing, research on recycling by-products has been actively conducted. In the industrial by-products, the high calcium fly ash(HCFA) produced by the blast-furnace in the circulating fluidized bed combustion method has a high ratio of CaO and CaSO4. In view of this, the purpose of this is to use high calcium fly ash(HCFA) as a stimulant in blast furnace slag powder and use it as a cement substitute. As a result, it is judged that the substitution ratio of HCFA should be 15% or less. In addition, although durability and strength are relatively lower than of OPC, it is considered that it can be utilized as an environmentally building material.

Fashion luxury products, which used to mean high-quality, handcrafted not-so-trendy items, are nowadays regarded as expensive fashion merchandise produced under the name of imported well-known brands. People cunsuming fashion luxury products distinguish themselves from other people according to the luxury fashion brands they are using, and as a result, advertisements of fashion luxury products are taken as a kind of international language. The purpose of this study is to point out the socio-cultural meanings of consuming fashion luxury products, by analyzing images shown in advertisements of fashion luxury products focusing on women's images. To do so, this study is based on general theoretical background on fashion, consumer culture advertising and analysis advertisements of fashion luxury products shown in fashion magazines in recent three years. The result of this study is as follows; The images of the advertisements of fashion luxury products could be categorized as (1) elegance, (2) kitsch and (3) fetish. Elegance is a taste of high society, aesthetically chic and feminine. Fashion luxury products, which are merchandise of extravagance, dignity, refinement, feminity and harmony, exhibit high-quality grace through their advertisements. Kitsch represents the vulgar and popular images of trivial commodities of industrial society. In the advertisement of fashion luxury product, it is shown as inappropriateness, excessiveness, stereotyped pleasantness, exaggeration an playful satisfaction. Finally, fetish images represent erotic or perverted sexuality, based on psychoanalytic fetishism which objects are regarded s substitute of sexual orgasm. The advertisements of fashion luxury product are characterized as (1) popularization of luxury, (2) objectification of sex and body, and (3) re-aestetification of anti-aesthetics. The asvertisements of fashion luxury products are actually targeted to the middle class with successful career women's images. They objectify female bodies through fetishistic images. Also, the deviant subcultural style, represented a new kind of cultural capital, is now reproduced as a new commodity aesthetics.
