Mungyung area has contributed to korean industrial development with its abundant natural resources. However, the change of industrial structure caused the decrease of the number of mines in Mungyung and it resulted in the economic depression in that area. Recently. the economic growth of Mungyung is attempted by developing the distribution center of agricultural products and the resort complex using beautiful natural environment such as the film setting of 'Taejo Wang - gun' and hot spring in good quality. In this article I survey the foreigners aware of the principle products of this district and their intention of purchasing the products using local speciality. I also make confectionery experiments on the basis of the survey and develop various confectionery using principle products of Mungyung.

Most warranty studies assume that the usage intensity is the same for all buyers. However, in real life the usage intensity varies across the population of buyers. In the general case, one can divide the population into $\kappa$ categories. This has implications for manufacturers of products. Should a manufacturer produce one product and offer different warranties for the $\kappa$ groups or produce different products (one for each group) and offer the same warranty. A warranty cost analysis is needed to choose between these options. The analysis complicated by factors such as adverse selection , buyers attitude to risk and the price structure. In this paper we develop models to study the expected warranty cost for products with free replacement warranty with varying usage intensity. Numerical examples are presented.

Due to the increasing demand for convenience and simplicity, Home Meal Replacement (HMR) has become a key trend in the food service industry. This study researched the current consumer trend and analyzed the national and international HMR product trend, aiming to find useful insights for the field. Results showed that in order to expand the HMR market demand, it is possible to consider diversifying the product category by making customized premium products, such as products for the elderly, infants, patients, and sports players, or products with enhanced nutritional fortification. From the industrial aspect, centralization through Central Kitchen (CK) and implementation of the scientific and advanced ISO and HACCP system are necessary. Lastly, to develop high value-added HMR products, it is deemed essential to utilize the so-called 'food tech', the technology which integrates core technologies of the fourth industrial revolution into the food industry.

This survey reports on the extensive examination of the qualify of 14 jogging and tennis shoes separately, availavable in the domestic market, Both jogging and tennis shoes were catagorised in two groups, namely the general goods(less expensive ones) and the exclusive goods(expensive models). The detailed classification are shown below; The domestic products meet the general purpose just as that of the foreign products. Due to the adhesion technology, the domestic tennis shoes consist of rubber sole with natural leather upper;In fact, the desirable combination, as foreign products, must be polyurethane/natural leather. The expensive models were heavier than the less expensive ones. The greater weight difference of right and left shoes are shown in the expensive models than that of the less expensive ones. The moisture absorption ratio of the expensive model is far superior in comparison with the less expensive model. The reason is identified by the material supplyed to produce the expensive model consisted of the natural leather and proper parts. The abrasion resistance of the expensive models were excellent that of the less expensive ones, because the rubber soles were showed the properties better than polyurethane sole which was used in the less expensive model.

본 논문은 마크업방정식을 설정하여 8개 제조산업의 산업별 마크업을 추정한 다음, 자기회귀시차모형을 추정하여 마크업의 요소가격탄력도를 산업별로 추정하였다. 또한 산업의 특성을 반영하는 산업의 자본집약도와 수입중간재비중을 고려하여 생산요소가격이 마크업을 결정하는 중요 변수임을 밝히고 있다. 분석결과 수입중간재비중이 높은 기계 전자 운송, 화학제품 그리고 금속제품산업에 있어서 마크업의 수입물가지수탄력도는 각각 -1.025, -0.176, -0.260으로 추정되었으며 자본집약적인 산업인 화학제품, 금속제품 그리고 기계 전자 운송의 경우, 이자율탄력도는 각각 -0.165, -0.147 그리고 -0.210으로 나타났다. 따라서 마크업의 주요 결정요소는 생산요소가격 그리고 산업의 특성을 반영하는 자본집약도와 해외중간재 비중이라 할 수 있다. 분석결과는 산업의 자본집약도가 클수록 그리고 해외중간재 비중이 큰 산업일수록 이자율과 수입물가지수의 변동은 산업별 마크업을 결정하는데 있어서 더욱 큰 영향을 주었음을 밝히고 있다.

본 연구에서는 각종 산업부산물(플라이애시 2종, 페트로 코크스 연소 유동층 보일러 애시 및 고로 슬래그 미분말)을 활용한 싱크홀 복구용 경량 충전재 제조에 관한 연구를 수행하였다. 이를 위해 혼합물 실험계획법을 적용하여 산업부산물의 배합비에 따른 혼합 원료 물성(압축강도) 거동을 검토하였고, 상용프로그램인 MINITAB을 사용하여 통계적 분석을 하였다. 산업부산물의 배합조건별 압축강도는 고로 슬래그 미분말에 강한 의존성을 나타냈으며, 압축강도(3일 재령)는 고로 슬래그 미분말 사용량에 3~11MPa 수준이며, 유동층 보일러 플라이애시의 사용은 압축강도 발현에 미치는 영향이 가장 적은 것으로 평가되었다. 그리고 혼합물 실험계획에 따른 원료 배치 1조건에 대해서 기포 콘크리트를 제조하여 압축강도와 투수계수를 측정하였으며, 이때 부피비중 0.9~1.0, 겉보기 기공률은 30~50% 수준, 압축강도(3일 재령)는 1~2MPa 수준, 투수계수는 $10^{-2}{\sim}10^{-3}cm/sec$ 수준이다.

This study aims to solve environmental problems by reducing complex degradation and recycling industrial waste by utilizing waste fibers and blast furnace slags, which are industrial by-products. In addition, it is intended to secure long-term durability to reduce cracks. To this end, the disadvantages of fiber-reinforced concrete are to solve the problem of lowering liquidity and ensuring curing time, and to find the optimal combination when waste fibers and blast furnace slag are used together.

Dodecanol에 ethylene oxide(EO)와 isopropylene oxide(PO)를 각각 5, 10몰 씩 부가하고, EO 부가물에는 PO를 PO 부가물에는 EO를 또 다시 5, 10몰 씩 부가시킨 다음 클로로술폰산으로 황산화시켜 8종의 음이온계면활성제를 합성하였다. 8종의 sodium poly(oxyethylene, oxyisopropylene) dodecyl ether sulfate에 대한 EO 및 PO의 부가를 확인하기 위하여 고성능액체크로마토그래피, 프로톤핵자기공명스펙트럼, 히드록시기값, 적외선스펙트럼을 사용하였다. 그리고 황산화를 확인하기 위하여 스펙트라와 Epton법을 이용하여 EO 및 PO 분자수를 확인하였다. 이 결과 황산화 반응의 최종 생성물의 수율은 90~96%로써 비교적 높게 얻을 수 있었다.

Technology opportunity discovery (TOD) based on technological capability is a process which identifies new product and technology items that can be developed by utilizing or improving a firm's existing products or technologies. By taking into consideration the investment risk of R&D and its practicality, developing technological capability-based TOD methodology is considered to be important for both business and research. To this end, we propose a technological capability-based TOD method and its system using TOD knowledge base. The method can support four types of TOD cases, which are based on a firm's existing technologies and products, and TOD knowledge base is developed by using function information extracted from patent documents. In this paper, we introduce the overall framework of the method and provide application examples on the four TOD cases using the prototype system.
