덕진산성은 고구려에 의해서 처음 축조된 성벽을 통일신라시대에 여러 차례 이상 수축하였고, 이후 필요에 따라 조선시대까지 사용된 것으로 확인되었다. 대략적인 시기를 살펴보면 초축은 삼국시대 말 즉, 6~7세기대로 추정되며, 축성주체는 고구려일 가능성이 높다. 또한 그 공간적 범위는 내성 전역에 해당할 것으로 판단된다. 이와 관련된 근거로 고구려에 의해 축조된 토축부[치3]에서 출토된 장동호와 시루편, 그리고 주변에 위치한 호로고루와 보루들의 축조시점, 그리고 자연과학적 분석결과 등을 들 수 있다. 이후 7세기 후반에 이르러 통일신라에 의해 1차성벽[석축부]이 축조된 것으로 보인다. 그리고 2개의 치와 치 기저부 강화를 위해 설치한 기단보축은 8세기대에 축조되었으며, 마지막으로 9세기대에 이르러 전면 가공한 화강암제 성돌을 이용하여 2차성벽을 축조한 것으로 판단된다. 한편 치3에서 확인된 치 기단보축의 축조수법이 주변에 위치한 고구려 보루[무등리 2보루, 홍련봉 2보루]의 축조수법과 매우 유사한데, 이는 고구려 멸망 후 고구려의 축성기법이 유입된 것으로 이해할 수 있다. 이후 조선시대에 들어 내성의 성벽을 기저부로 활용하여 외성을 축조하였으며, 외성문지 토축부와 내ㆍ외성의 연접된 토축부에서 고려~조선시대 기와편과 백자편이 출토되어 편년에 좋은 근거가 되고 있다. 그러나 아직까지 외성에 대한 초축시기나 축성주체, 그리고 동파리보루와 덕진산성과의 관계는 명확히 단정하기 어려운 상황으로 장기적이고, 체계적인 후속조사가 이루어지면 좀 더 구체적인 면모가 밝혀질 것으로 기대된다. 특히 덕진산성 내성과 관련된 문지, 집수지, 건물지 등에 대한 종합적인 조사가 실시되어야 할 것으로 판단된다. The rampart of Deokjinsanseong fortress(德津山城) which had been first constructed by Goguryeo was repaired several times during the United Silla period, and it was found that it was used till the Joseon dynasty as occasion demanded. To examine the approximate periods, it is assumed that it was first built at the end of the period of the Three States, that is, the 6th to 7th century, and it is very likely that Goguryeo was the subject of the construction. In addition, it is judged that its spatial range may be the entire area of the inner castle. The grounds for this include jars with a long body (jangdongho) and steamers (siru) excavated from crenellated wall (chi) 3 of the parts constructed with earth, built by Goguryeo, the period of the construction of Horogoru Castle and forts that are located around it and the results of a natural scientific analysis. Later, it seems that, entering the late 7th century, the parts constructed primarily with rocks of the rampart was built by the United Silla dynasty. In addition, it is judged that foundation subwall (gidanbochuk) installed to reinforce two crenellated walls and their base was constructed in the 8th century, and in the 9th century, the rampart was constructed secondarily, using fully processed granitic castle rocks. In the meantime, the method of the construction of the foundation subwall of the crenellated wall found in crenellated wall (chi) 3 is very similar to that of the Goguryeo forts located in the surrounding areas (Fort2 in Mudeung-ri and Fort2 in Hongryeon- bong), and this can be understood that after the fall of Goguryeo, its fortification was introduced. Later, in the Joseon dynasty, the outer castle was constructed, using castle wall of the inner castle as the base, and in the parts constructed with earth in the outer castle and the parts constructed with earth in the part where the inner castle and outer castle are connected, fragments of roofing tiles and white white porcelain of the Goryeo to Joseon dynasty were excavated, which become nice grounds for chronological recording. However, it is still difficult to clearly predicate the period of the first construction of the outer castle, the subject of the construction, and the relationship between Dongpa-ri fort and Deokjin mountain fortress, and it is expected that more concrete aspects will be revealed if long-term and systematic investigations are carried out. Especially, it is judged that comprehensive investigation on gate ruins, water catchment ruins and building sites related to the inner castle of Deokjin mountain fortress should be conducted.

This study targets to estimate the performance of an organic Rankine cycle (ORC) power generation system using dual expanders by simulation and experiment. The ORC system is composed of two scroll expanders installed in parallel, a hydraulic diaphragm type pump to pressurize the working fluid, two plate heat exchangers for the evaporator and condenser. The two scroll expanders were converted from two oil-free air scroll compressors with same specifications, and were tested in the ORC loop with R245fa. The heat source temperature was controlled up to 150 °C by the 150 kW-class electric water-heater. In order to evaluate the static performance of the system, efficiencies and shaft powers for both single and dual operation mode were carried out. The maximum isentropic efficiency of each expander was measured about 70 %, and the shaft power was reached to about 3 kW at the turbine inlet temperature of 140 °C. Moreover, the performance characteristics of the dual parallel expanders ORC system with regards to various heat source conditions will be addressed.

The necessity for diagnosis and management of pipes has emerged as the issue since contamination of water supply due to corrosion of pipes. Although inspection has been performed with industrial endoscopes, the method has limits for full diagnosis of pipes due to lack of working range. As a solution for this problem, a locomotive mechanism for a microrobot with endoscope functions is proposed. In the proposed locomotive mechanism, it has band-type legs actuated by the synchronized motion of a linear actuator and a moving cylinder. To verify the feasibility for the locomotive mechanism, velocity along a sloped path and thrust generated in a vertically arranged pipe have been analyzed by performing an experiment in a transparent acrylic pipe which has a diameter of 16㎜. The proposed locomotive mechanism is not only applicable to inspection of small pipes in diameter but also expected to move in human digestive organs.
The Impact of Customer-Centric Strategy for Brand Creation
Hyunjun Park(박현준) 융복합지식학회 2018 융복합지식학회논문지 Vol.6 No.2
This research investigates how the brand of a company is vital for sustainability and growth. Typically, companies follow the market trend to produce products by analyzing the market only. However, this approach can have short-term profitability. On the other hand, the customer-centric strategy can create a brand where customers are aware and can trust a specific company because of their specific brand entity. Thus, this paper will focus on the customer needs as a priority instead of following the market trend. Moreover, it produces products that can benefit the customer instead of creating a better product to gain market share. Therefore, this research paper explored a cosmetic company called Pinkwonder which have successfully utilized and applied the customer-centric strategy from the beginning and created an organic cosmetic brand where the customers can trust. Currently, the organic cosmetic industry is trendy and attractive industry, especially in South Korea. Thus, there are many different competitors with various organic products to match and follow the current market trend. Therefore, these companies have followed the market trend and have obtained some of the market shares. This paper will explore the differences and importance in brand creation for growth and sustainability between the market trend follower versus customer centric-strategy. Also, it will attempt to discover that the customer-centric strategy may be more viable and sustainable in the long-term.
