(Background and Purpose) A study of antecedents related to corporate buildings shows that a variety of studies have been conducted on the floors lower than the lobby. Therefore, identifying motives behind visits in utilizing the office building as a place for communication with the public is an important starting point for understanding and predicting public behavior. This study examines the effect on the formation of corporate image by eliciting the motivation behind the public’s visit-related keywords in the shared space of the corporate office building through text-manning. (Method) The scope of the study was to analyze the shared space inside and outside corporate offices that were opened to the public, and the selection of analysis companies was made by selecting AmorePacific and Naver, the top two companies of keyword, using Texstorm to analyze consumer responses. The research methods included first, considering corporate image, space in corporate office building, motivation for visit and satisfaction theoretically through prior study and literature. Second, investigating and analyzing public reactions through social network-oriented text-manning. Third, deriving results from the analysis regarding the motivation behind public visits. (Results) First, AmorePacific’s Building and Naver’s Library can be inferred as the keywords of attraction and interest for each company that the public now considers a key element of the destination-related decision. Second, both companies can be inferred by visiting the office building as a venue for appointments and meetings. Third, the use of food and beverage space at destination can be inferred through the keywords, caf‰ and taste house.” Naver, on the other hand, is seen as a customer’s need because the keyword for the restaurant was derived even though there are no restaurants available to the public in its office building, which could not meet public expectations and desires. Fourth, both companies have come up with the keyword, free and are expected to have a positive impact on customer satisfaction through free content, and direct experience through keywords, review, recommendation, and share will have a significant impact on the formation of potential consumers’ corporate image. (Conclusion) The public recognized the private space of a company as a space of culture and rest, and at a time when emotions were valued, it was an effective means of improving the corporate image. In other words, an entity can significantly influence the formation of a consumer’s corporate image by emphasizing the attractiveness of the destination that is a pull factor and by making efforts to meet the expectations of the customer, an internal and emotional aspect of the push factor, while opening up the office building’s shared space.

(Background and Purpose) Identifying consumer behavior is an important starting point in understanding and predicting consumers in an online environment that is becoming more competitive. Therefore, analyzing online consumers’ consumption experiences and deriving implications by identifying their inner psychological factors is the objective herein. (Method) The scope of research is analyzed with domestic consumer’s social media online consumption experience data. The first research method proceeds with online consumption experience, consumption value, and risk factor theoretical considerations. Second, the framework of key text analysis and text mining through big data research methods are presented. Third, through analysis results, we identify the psychological factors affecting online consumption behavior and derive implications. (Results) First, the consumer values that affect online consumption behavior are largely divided into functional and emotional factors: from a functional perspective the benefit factors are classified as satisfactory information, convenience, and cost-saving, while the risk factors are classified as product-related risks and internet media transaction risks. Second, consumers were understood to purchase online due to the benefits of satisfactory information and cost-savings on online platforms. However, there was a high desire to solve the uncertainty felt by consumers during the purchasing stage, and that uncertainty was solved through satisfactory information. Third, the greater the satisfactory information value, the more they prefer information through human exchanges. Information through human exchange builds trust in consumers. Thus, when trust is broken, consumers think that they have suffered damage. Furthermore, it may have a negative impact, on the company such as losing loyal customers or having bad online reviews, which can lead to a bad reputation for it. Fourth, consumers who value experience are going to feel greater risks over value in online consumption, thereby finding it difficult to purchase. Therefore, it is understood that consumers will prefer a brand the official website of which guarantees high-quality products as well as professional customer service for exchange or refund. Fifth, consumers with greater cost-saving values are going to feel more satisfaction when purchasing online and are more likely to write positive reviews. Last, consumers with greater convenience values are going to find the efficiency of information-searching and cost-saving more important. When there is too much information released for the products, customers may have a hard time making their decision. In this case, brand power can be a huge factor influencing buying. (Conclusions) Through analysis, we were able to see the importance of efficient consumption, brand image, and information through human exchange. Moreover, the expected value losses and the uncertainty of value in the limitations of the online environment will negatively affect online consumption, psychological satisfaction, and brand image.

(Background and Purpose) Understanding environmental changes and analyzing changes in public perception of the consumption space for the development of offline space-oriented industries is an important starting point to comprehend public consumption behavior and predict changes in related industries. Therefore, in the context of the COVID-19 pandemic, text mining was used to determine changes in public perception of the consumption space. Based on this, the purpose of this study was to derive the role and implications of the offline space-oriented industry ahead of the post-COVID-19 era. (Method) Text mining was performed using Textom to analyze public perception of the consumption space. Data collection was conducted throughout the first and second half of 2020, when deterioration and mitigation were repeated in terms of timing; the changes in public perception were derived from a comparative analysis that was conducted on the collected data. (Results) First, although there was a concern regarding the overall atmosphere of society, the public’s flexible response was based on quickly adapting to the sudden changes caused by COVID-19. Second, four attributes of the consumption space were not removed or added, and only detailed objectives could be seen to change. As can be seen from these results, future spaces need to flexibly change their purpose and structure. Third, the word offline did not disappear in the data from the second half of 2020. Through this, even if the COVID-19 situation worsened toward the second half of 2020, the public's desire for, and the necessity of, offline spaces remained. In addition, digital technology was developed to communicate online, but as offline exchanges and face-to-face contact were restricted, the public’s overall level of depression increased. Fourth, based on the difference between physical and psychological consumption keyword clusters in the first and second half of 2020, we found that the longer the COVID-19 situation goes on for, the more people look for offline-oriented consumption spaces for internal or surrounding consumption. (Conclusions) Exchange and communication are expected to be an area that cannot be replaced or resolved online, which is expected to be an important keyword for the changing offline space-oriented industry. Therefore, it is necessary to flexibly change the purpose and structure of the space in line with the rapidly changing environment, and a strategic approach to exchanges and communication in offline-centered consumption spaces is needed.

CuInSe2 단일전구체에서 스퍼터링된 박막의 광학적, 구조적 및 전기적 특성평가

정채환(Jeong, Chaehwan),김새록(Kim, Saerok),김진혁(Kim, Jinhyeok),김광복(Kim, Kwangbok) 한국신재생에너지학회 2010 한국신재생에너지학회 학술대회논문집 Vol.2010 No.06

Cu(In,Ga)Se2 (CIGS)박막태양전지는 간단한구조와 가격경쟁력 및 고효율화 가능성에 대한 기대감에 의해 많은 연구가 수행되어오고 있다. 특히 높은 흡수계수와 적절한 밴드갭, 큰 결정크기와 같은 물질의 특성들이 장점으로 작용하고 있기 때문이다. 또한 CIGS박막태양전지는 다른 태양전지에 비해 광열화가 적다는 장점도 가지고 있다. CIGS 박막은 CuInSe2내의 In 사이트에 Ga을 도핑함으로서 형성이 되는데 그때의 밴드갭은 약 1.4eV이며 이를 형성하기 위해 많은 방법들이 제안되고 있는데, CIGS박막 형성 시 가장 중요시 여겨야 될 인자는 구성원소로부터 최적화된 조성비를 찾는 것이다. 이러한 관점에서 볼때 evaporation법이나 sputtering법같은 진공방식의 공정법이 비진공방식에 비해 최적의 조성비를 찾는 것이 수월할 것으로 생각된다. selenization을 하기전에, 동시증착이나 다층박막형성을 통해 Cu-In-Se의 조합이 일반적으로 이루어진다. 어떤방법이든 Se의 부가적인 공급이 이루어지는데 시작 전구체의 조합에서 그 해법을 제시하는 것에 대한 논의가 많이 부족한 현실로서, CuInSe2의 단일전구체에 의한 박막형성과 특성평가에 대해 구체적인 논의가 필요하다. 본 실험에서는 Cu-In-Se 전구체를 CuInSe2 단일 타겟에서부터 RF 마그네트론 스퍼터링법을 이용하여 박막증착을 하여 Se의 Rapid Thermal Process(RTA)법을 통해 Se이 순차적으로 공급되었다. 이때 형성되는 박막의 태양전지 흡수층 적용을 위한 광학적, 전기적 및 구조적에 대한 논의된다. Soda lime glass(SLG)와 Corning 1737 유리를 기판으로 하여 아세톤-에탄올을 이용, 초음파세척을 실시하였다. 스퍼터 공정을 하기전에 흡착된 물분자를 제거하기 위하여 약 30분간 120?C로 열을 가해주었으며, 공정을 위한 총 아르곤 가스의 양은 약 50sccm이며 이때의 공정압력은 20mtorr로 고정하였다. 우선 RF power와 기판온도에 따른 단일전구체 형성을 관찰하기 위하여 각각 30~80W, RT~400?C로 변화를 주어 박막을 형성한 후 모든 sample에 대하여 500?C분위기에 effusion cell을 이용하여 Se 분위기에서 결정화를 실시하였다. 샘플의 두께는 Surface profiler로 측정하였고 단면은 전자주사현미경으로 관찰되었다. 동시에 SEM이미지를 통하여 morphology와 grain size 및 EDX를 통하여 조성분석을 하였다. 밴드갭, 투과율 및 흡수계수는 UV-VIS-NIR분광분석법을 통하여 수행되었으며, 전기적 특성분석을 위해 4-point-probe와 Hall effect측정을 수행하였다. 공정변수에 따른 단일타겟으로 얻어 결정화된 CuInSe2박막의 자세한 결과와 논의에 대하여 발표한다.

본 연구는 2013년 영남대학교 융항협 디자인대학육성사업의 일환으로 포항시청 테라노바팀과 연구 개발한 `접근 유도를 위한 보행 네트워크 구축에 관한 연구`의 진행과정과 디자인 제안에 대해 정리하였다. 이를 통해 특정지역에 대한 접근유도를 위한 보행 네트워크 개발에 있어 개념의 도입과정과 보행 네트워크 구축에서 고려되어야 할 부분과 진행과정 전반적인 이해를 돕고자 한다. 본 연구에서는 포항시를 대표하는 중심상권인 중앙상가 실개천거리에서 도심해수욕장인 영일대해수욕장 일대까지 방문객들의 동선을 유도하여, 집중된 관광 인프라를 주변 지역으로 분산시킬 수 있는 방안을 제시하였다. 이를 통해 방문객들이 다양한 체험과 관광을 즐길 수 있도록 하며, 각 거점별 디자인 방안을 마련하여 포항시만의 정체성을 찾고 도시 품격을 높일 수 있도록 하였다. The concerned study reviewed a process and a design proposal of a `project on securing of pedestrian network for approach guidance` which had been conducted in cooperation with Team Terranova as a part of a project to promote an integrated design college of Yeungnam University in 2013. In doing so, the study improved the general understanding of relevant fields on how to deal with the concepts and other matters to be considered to secure the pedestrian network when the fields try to develop the pedestrian network for the approach guidance in a specific area. The study proposed an idea to disperse the concentrated tourism infrastructures into other adjacent areas by guiding traffic lines of visitors from Street Silgaecheon of Central Shopping Mall, the greatest business district in Pohang, to Yeongil Beach, one of the beaches in Pohang. Design plans for each area that the study has proposed will provide visitors with chances to enjoy even more various experiences and attractions while taking the class of the city up to another level, helping Pohang finally find its own identity.
