This study conducted surveys on perception and utilization of Korean soybean paste targeting 493 women from their 20s to 60s residing in Daegu. Most subjects married (75.3%), were part of a nuclear family (84.8%), had more than a high school diploma (95.8%), had a career (47.9%), lived in an apartment (68.4%), had a total household income of 5 million won or more (38.1%), and had monthly food expenses more than 0.5 million won and less than 1 million won (42.2%). Regarding perception, 'rich nutrition' was the most commonly held perception in subjects in their 60s (4.4), followed by 'good taste' in subjects in their 40s (4.3). Regarding reasons for consumption 'healthy' was highest in subjects in their 60s (47.3%) and 40s (45.6%) and 'delicious' in subjects in their 20s (56.1%). Regarding how to make it, subjects in their 60s responded 'know for sure' (57.1%), while only 2% of 20s responded the same. Subjects in their 50s and 60s had a higher ratio of answering 'know' while 20s and 30s 'don't know', For preparation methods, subjects in their 20s (53.1%) and 30s (41.4%) answered 'buy at the market', subjects in their 40s (68.9%) 'get from family or relatives' and subjects in their 60s (47.3%) 'make by one's own'. For preservation method, subjects in their 20s and 30s answered 'preserve in refrigerator', the 60s tend to answer 'preserve in jangdokdae'. Buying at the market was most common in subjects in their 20s (36.1%) and 30s (28.5%) and the reason was 'convenient' (39.6%). The place of purchase was 'in large supermarket or department store' (78.5%). For the future consumption pattern, 'increase in consumption of commercialized product (44.0%)', subjects in their 60s answered 'keep making at home' while subjects in their 30s and 40s answered 'keep making at home or buying product half and half'. According to the above study results, women living in Daegu region were aware of excellence of traditional soybean paste. However, due to changes in residential circumstance and lack of knowledge about the recipe, they did not make. They receive soybean paste t from family, relatives or bought in the market, which indicates the continuous decrease in home-made soybean paste. Therefore, due to the expanding social participation of women, the product market is expected to increase. I think it is important to develop traditional commercial soybean paste in the traditional way to improve the traditional flavors.

The platform concept has been used for business operations in various forms: product platforms, transaction platforms and industry platforms. All these platforms have common characteristics of having 'core' that is reused frequently and 'peripherals' that are less reusable and changed often. Companies use platforms to enable efficient development and creation of product family, transactions and innovation. These platforms provide new opportunities for many small and medium-sized companies (SMEs) by bringing changes to traditional industrial structures focused on the products rather than platforms. The service robotics industry in South Korea is mainly composed of technology-intensive SMEs due to its small market size. Although these SMEs succeed in developing technologies, they have difficulties creating and expanding markets to sell products. Thus, this study addresses the characteristics and problems of the South Korean service robotics industry and analyses how ROBOPRINT, one of the SMEs in the service robotics industry, successfully creates and continuously expands the service robot market by adopting platform concept. The results indicate that ROBOPRINT has been applying two types of platforms: product and transaction platforms. First, ROBOPRINT created art robots that were apartment mural service robots. Rather than selling art robots, the company developed various robots such as painting robots, building exterior wall-cleaning robots by reusing the core technology of the robots. The company also developed various robots according to the buyers request. In addition, the company used the robots to directly provide apartment mural services for customers. This mural service has been extended into various areas, not only in apartments but also in soundproof walls, underground passages, and retaining walls. Besides, ROBOPRINT added new services continuously by developing technologies such as virtual reality. Second, ROBOPRINT mediated mural service buyers and mural designers. This platform reduced buyers' workload, which necessitates requesting mural services to ROBOPRINT and searching for mural designers. For designers, this opened up new opportunities to participate in the mural business. The platform attracted both mural buyers and designers who were scattered before. Finally, ROBOPRINT seeks to expand the platform's scope to outside company. To share internally reused ROBOPRINT's technology with other companies, the company participated in Daegu city's 'New Technology Platform Industry'. Furthermore, ROBOPRINT is trying to share the service platform by leasing robots to other companies. This allows external agents to develop technologies and provide services by reusing resources from ROBOPRINT. This study contributes to existing theories by showing that SMEs continuously create and expand markets by building various platforms. Moreover, it provides useful implications for practitioners by describing the firm's specific platform-building strategy.

The demand of ubiquitous home network system is rapidly increasing in Korea as each construction enterprise makes a huge effort to introduce it to apartment complex. However, the design of home network system is rather technology oriented than the customer focused. Lack of knowledge about customer needs is an obstacle in spreading the ubiquitous home network system to the market regardless of technology development. In this paper, we propose a HCSI(customer satisfaction index for home network system) using an SEM(structural equation model) where structural relationship among several factors influential on users' satisfaction is considered. This model enables to calculate the satisfaction index for target customer group so that one can provide necessary feedback information for improvement of the home network system used for each group.

This study aimed to seek a method capable of hedging a rising risk of housing rent price by introducing derivatives with the target of Korean housing rent markets. The research model used in this thesis progressed a research by applying a futures contract method with the target of the rent price of major apartments in Gangnam and Gangbuk Regions of Seoul. As an analysis result, the rent price of all complexes has risen during its analysis period, so it could be confirmed that the CRB future index was also risen according to this. Finally, it was confirmed that the rising risk of the rent price can be hedged through a purchase position of futures. But, as the difference between rent price variation and CRB future index variation occurs, it appeared that 100% of hedge is difficult. However, it is judged that if considering that a method capable of hedging the rising risk of the existing rent price was nonexistent, the hedge trading effect utilizing the CRB future index on the rent price will be meaningful.

The purpose of the study was to supply the demand prediction of housing market with useful information by identifying housing preferences as housing norms of family levels. The survey uses questionnaires which are delivered to the 329 households who live in more $66m^2$-less than $99m^2$(2 0pyoung) or more $99m^2$-less than $132m^2$(30 pyoung) multi-family dwellings in Ulsan. The frequency test, t-test, factor analysis and One-Way analysis were used for the analysis of the results. more than half of households have held house-moving plan within 3 years. most of them have desired to live at the high-rise apartment in Nam-Ku area and have wanted wide size through an average of $3.3m^2$(10 pyoung) than present house size. It was revealed that the characteristics of moving behaviors, residential areas and housing preferences were significant variables which affected to housing satisfaction.

A drill & blasting method using explosives is the most efficient way to break the rock in the urban projects. However, the blasting method cause vibration, noise and fly-rock as blast pollutions so that blasting wroks are restricted by adjacent structures such as apartment and residence houses. To conduct blasting works at near structures, the numbers of blast-holes a blast and the size of the blast are limited by kinds of detonators and initiation methods. So, the production rate is reduced and the construction period should be increased. Therefore, in this case the deck-charge blasting methods using available detonators in domestic market were designed and evaluated in order to confirm the application possibilities in specific urban sites.

Given importation of After-Sale System, we may assume that it comes to be changed on housing industry Construction companies have applied installment sale to fund of building, but now they have to take it upon themselves to borrow from PF(Project Financing) on the banking system. The purpose of this study is to assume the change and influence in the construction fund after adopting After-Sale system and suggests the appropriate strategy in PF for providing fund. Construction Companies can produce their Profits by concentrating on reconstruction part especially in the metropolitan area. And They make their own brands and have their competitive power. In this housing market, if After-sale system comes publically, there will be big changes. Until now many companies have no difficulties in making funds to manage construction activity. But After-sale system gives difficulties to many companies. Therefore they have to prepare their own funds under their responsibilities from banks of Project financing.

In response to the economic depression, the demand for fixed rent income has increased according to the easing construction regulations. it caused indiscriminated investment to stakeholders. This leads to oversupply in the multi-family Housing market and increases unsold housing and vacancy rates except specific area such as Gangnam-gu.In order to solve this issue, although studies on the optimization price of apartment houses has been conducted, the study is insufficient regarding on residential officetel. Therefore, the objective is to suggest a basic study on optimal price estimation model development by using probabilistic forecasting method in planning phase. To achieve the objective, first, variables are defined such as expenses, financial costs, income, etc. Second, causal loop diagram is suggested. Third, basic optimization prices estimation model is developed. In the future, this study can be used as one of decision making tools in planning phase of officetel development projects.
