In this study, I analyzed the inducing and hindering factors of online shopping malls on browsers in the process of browsing fashion products in online shopping malls. In-depth interviews were conducted by presenting browsing-related questions to women in their 20s and 50s who are interested in browsing fashion products online. Based on the answers of the interviewees, using grounded theory, we analyzed and presented six factors such as price factor, promotion factor, purchase review factor, visual information factor, product information factor, and service factor. Based on inducing and hindering factors to browsing analyzed in this study, a strategy to design a browsing environment in terms of shopping malls was suggested, which will be helpful for practical strategies and marketing in related industries. Basic data will be presented in a thesis on a new type of shopping mall browsing environment related to the rapidly developing information and communication technology. In addition, the negative emotions experienced in relation to the detrimental factors of shopping malls in the browsing process are expected to be helpful in researching fashion product browsing related to consumer psychology.

In the design process that focuses on problem solving, in general, two or three barriers to design creativity appear at the same time and are linked to increase difficulty. Because the design problem always arises in unusual, unique, weird, and difficult to define, it is not possible to extract the correct answer through the formula and the answer is always plural. This study aims to present solutions and prove their effectiveness as a follow-up study that seeks to overcome the representative obstacles to design creativity discussed in the previous study. To this end, a qualitative study was conducted to find solutions to the obstacles suggested in the previous study and to devise key solutions(creativity development cards). At the same time, a quantitative research methodology using experiments and statistical analysis was adopted. After grasping the core characteristics of an object using the creativity development card, it was able to approach the creative solution by utilizing the reductive analysis of the original such as transformation of the core characteristics, reconsideration of essential problems and intentional differentiation. As a result, it was confirmed that the proposed solutions were effective not only as a method of overcoming the barriers to design creativity, but also in improving creativity.

객체지향 패러다임에서 응집도가 높은 클래스들은 단 하나의 데이터 요소만이 정의되고 모든 메소드(또는 연산)들이 그 데이터 요소 상에서 수행되거나, 메소드와 데이터 요소간에 최대연결이 이루어진 클래스이다. 따라서 데이터 요소의 증가와 최대연결을 저해하는 연산들은 클래스의 응집을 저해하는 주 요인들이다. 본 연구에서는 이러한 저해요인들에 근거하여, 응집도에 관한 우리의 직관과 더욱 일치하는 측정을 할 수 있는 새로운 클래스 응집도 척도인 CM(Cohesion Metric)을 제안하였다. 본 연구에서는 응집도를 저해하는 요인의 식별을 위해 참조 그래프(reference graph)를 이용하고, 참조 그래프의 분석을 기초로 하여 클래스의 응집도를 측정하였다. 또한 제한된 CM 측정값이 응집도 척도가 만족해하는 특성들을 만족함을 보였고, 기존 응집도 척도들과의 비교평가를 통해서 CM이 기존의 척도들보다 향상된 측정을 제시함을 보였다.

This study was conducted to investigate the effect of pyroligneous acids on urea hydrolysis for the purpose of inhibiting ammonia volatilization during urea fertilizer application. Different types of synthetic urease inhibitors have been searched and developed, but their use is limited due to varying inhibition effects on soil urease, and environmental problems. In this study, the effect of pyroligneous acids, a natural substance, on urea hydrolysis in soil was evaluated by analyzing inhibition of urease activity. Pyroligneous acids inhibited plant urease and microbial urease activity, as well as soil urease with various urease complex. In addition, pyroligneous acids exhibited non-competitive urease inhibition effect through urease kinetics and inhibited urea hydrolysis in the soil. This study showed that pyroligneous acids treatment with urea fertilizer decreases the loss of urea fertilizer, improves the efficiency of nitrogen application on plant and reduces the amount of nitrogen fertilizers applied in soil.

평택 당진항은 지난 1996년 3대 국책항만 및 5대 국책개발사업에 선정된 이래 단기간 내 급속한 항만성장을 이룬 결과 지난 10년전과 비교하여 선석규모는 약 3.2배 증가하였으며, 지속적인 항만개발계획에 따라 2030년까지 총 92선석을 개발할 예정이다. 이러한 항만규모의 증가와 함께 선박입출항 및 화물처리실적 또한 2015년도 기준 전국 5위의 규모로 성장하였다. 하지만 항만의 수심, 항로폭, 정박지 규모 등 선박통항을 지원하는 기반시설의 개발은 상대적으로 부족하여 통항안전의 저해요소로 작용하는 바 이러한 항로와 정박지를 중심으로 선박통항안전에 부정적 영향을 끼치는 요소를 분석하고 그에 따른 개선방안을 모색해보았다.

모바일 디바이스가 기존이 PC 시장규모를 압도하면서 기하급수적으로 많은 모바일 앱이 출시되고 있다. 수많은 모바일 앱 중에서 사용자들은 배우기 쉽고, 직관적으로 사용하기에 용이한 모바일 앱을 선택하려는 경향을 보인다. 그러나 모바일 앱 사용성의 중요성이 증대됨에도 불구하고 모바일 앱에서의 사용성에 대한 연구는 미미한 실정이다. 현 GUI 사용성 테스트는 많은 시간이 소요되고 주관적인 평가에 의존하는 단점이 존재한다. 본 논문은 사용자들이 앱을 조작하는 터치 입력 데이터를 기반하여 EFSM(Extended Finite State Machine)에 인자를 추가한 형태로 모델링 후 개발자의 예상 시나리오와 비교하여 GUI 사용성 저해요소를 검출하는 기법을 제안하고 있다. 이와 같은 반-자동화된 방법을 통해 모바일 앱 상에서의 사용성을 측정할 수 있다. 제안된 기법을 구현한 도구의 구조를 설명하고 사용성 저해 요소 검출하는 과정을 기술하였다.

Lack of lysosomal fusion with symbiosomes in symbiont-bearing Amoeba proteus may be due either to the presence of a component in the symbiosome membrane or to the absence of a component needed in the fusion process. Using monoclonal antibody as a probe, lipopolysaccharides were identified as symbiosome-membrane components contributed by symbionts and were found to be exposed on the cytoplasmic side of the membrane. In order to test whether lipopolysaccharides may play a role in the prevention of lysosome-symbiosome fusion, the antilipopolysaccharides antibody was microinjected and processed for double immunostaining in conjuction with anti-lysosome antibody as a lysosome-fusion indicator. Microinjection of the anti-LPS antibody caused symbiosomes to fuse with lysosomes, suggesting that X-bacterial lipopolysaccharides could be 'fusion-preventing' factors.

After the introduction of the design VE system in 1990s, based on the legal system has made a rapid growth. Also It is evaluated as qualitative growth. Despite this growth, VE effort can cause the occurrence of the risk. In this paper carried out to hindrance factor that decrease the productivity in VE phase for strategy to improve the utilization of basic data.
