목적 : 본 연구는 현재 임상에서 사용되는 재질 방식으로 제작된 청색광 차단 렌즈의 광 투과율을 측정하여 특 성을 분석하였다. 방법 : 상측정점굴절력이 0.00 D인 일반 코팅 렌즈(CCL), 재질 방식의 청색광 차단 렌즈(BML)를 굴절률 1.56, 1.60 및 1.67, 코팅 방식의 청색광 차단 렌즈(BCLa, BCLb) 및 착색 방식의 청색광 차단 렌즈(BTL)를 굴절률 1.60 으로 각각 수집하여 광 투과율을 측정하였다. 결과 : BML은 굴절률이 증가할수록 광 투과율 및 분포 면적이 감소 후 더 증가하였으나 통계적으로 유의한 차 이가 나타나지 않았다(p＞0.050). 또한, BML의 청색광 차단 효과는 CCL보다 높은 것으로 나타났지만, 다른 제조 방식인 BTL, BCLa 및 BCLb 보다는 낮은 것으로 나타났다. 결론 : 재질 방식의 청색광 차단 렌즈를 권유함에 있어서, 착용에 보다 적합한 대상의 선별 및 사용 디스플레이 조건을 모두 고려하는 세심한 노력이 필요하다.

In order to provide priorities of the factors affecting the introduction of Smart Factory, This study reconstructed the factors and calculated the priorities through AHP (Analytic Hierarchy Process). The first layer of the hierarchy have 4 factors; productivity increase, brand image improve, marketing improve, cost reduction. The second layer of the hierarchy have 3 factors belong to the first layer, so the total number of second layer is 12. We divided the characteristics of enterprises into type of manager and age. The C.R. (consistency ratio) values of the respondents were found to be less than 0.1 and were judged to be a 'reasonable test'. As a result, the weights of the higher layer and the lower layer were obtained respectively, and then the weights of the higher layer and the weights of the lower layer were multiplied to obtain the total weights. Unlike previous studies that only surveyed factors that companies consider when introducing smart factory, (1) weighing and prioritizing factors were achieved. There are differences in priorities, (2) smart factory can be studied with the type of manager and firm age. When establishing policies, it is a practical implication (3) to assess its strategy not only for government officials but also for executives.

공공정원이 현대도시의 새로운 영역으로 등장하며 시민가드너 양성교육이 확대되는 현상에 주목하여, 시민가드너 교육 참가자, 참여의향자, 일반시민으로 집단을 구분하여 도시정원에 대한 이미지와 효과 및 공동체성을 분석하여 다음과 같은 결과를 도출하였으며, 교육 의의 및 활성화 방안을 함께 고찰하였다. 24개 형용사 어의구별척도를 이용한 도시정원 이미지 평가 결과, 자연과의 관계를 나타내는 “친숙한, 정서적인” 등의 어의변수와 정원활동에 대한 태도를 나타내는 “상호교류적인, 적극적인”, 그리고 공간적 평가와 관련된 “확장적인, 자율 적인” 이미지에서 상대적으로 높은 평가치를 보였다. 교육참 가자는 “자율적인, 지속적인” 등의 어의변수를 높게 평가하여, 도시정원의 형태나 디자인보다는 유지관리와 지속성을 중시함을 알 수 있었다. 주성분분석에 의한 요인분석 결과로부터 교육참가자 집단의 요인적재값을 중심으로 요인별 특성을 파악하면, 잠재적(Potential) 차원의 1 요인은 “도시정원의 공공적 역할과 공동체성”, 평가적(Evaluative) 차원의 2 요인은 “공공조경으로서의 차별성”, 활동적(Active) 차원의 3 요인은 “미적 체험성”으로 명명할 수 있었다. 도시정원 효과에 대해 교육 참가자일수록 사회적, 환경적 측면을 중요하게 인식하고 있었고, 공동체의식지표 평균값(3.4)은 잠재참가 집단(3.31)과 일반시민 집단(2.69)에 비해 높게 나타났다는 점에서 공공성 인식 상의 차이를 볼 수 있었다. 시민가드너 교육이 정원식물 지식 습득의 의미를 넘어 평생교육이나 공동체 활동으로 인식 된다는 점에서 지속가능성을 위한 교육의 체계화 필요성을 확인할 수 있었다.

This paper is a follow up to the previous study which reveals that smartphone users are divided into three subcategories according to their usage characteristics. In this paper, these groups are called as ‘general’, ‘entertainment’, and ‘work-assistant’, taking into account their respective characteristics. The ‘general’ is a group whose smartphone usage characteristics are not focused on a specific purpose, the ‘entertainment’ is focused on music, internet, SNS, picture, and e-banking, and the ‘work-assistant’ is on work, GPS, diary. Inter-relation between the importance and satisfaction for the purchase determinants to the groups is investigated. In addition, Kano analysis of quality attributes is also performed, which includes quality type, satisfaction/dissatisfaction index, and PCSI (Potential Customer Satisfaction Improvement) index. The analysis result are as follows. Firstly, inter-relation between importance and satisfaction differs by user group. ‘Internet’, ‘Ease of use’, and ‘Performance’ purchase determinants are evaluated as competitive determinants in ‘work-assistant’ user group. Secondly Kano quality types of quality characteristics also differs by user group. ‘Application’ was classified as an attractive (A) types to ‘entertainment’ group and so on. ‘Internet’ ‘Failure/Bug’, ‘Touch response rate’ and ‘Charging’ are located in ‘Nice’ Region of S-PCSI Diagram and have to be considered as strategic quality characteristics. The results of this study is expected to give some helps in establishing a customer tailored quality strategy.

Google Trends is a useful tool not only for setting search periods, but also for providing search volume to specific countries, regions, and cities. Extant research showed that the big data from Google Trends could be used for an on-line market analysis of opinion sensitive products instead of an on-site survey. This study investigated the market share of tumor necrosis factor-alpha (TNF-α) inhibitor, which is in a great demand pharmaceutical product, based on big data analysis provided by Google Trends. In this case study, the consumer interest data from Google Trends were compared to the actual product sales of Top 3 TNF-α inhibitors (Enbrel, Remicade, and Humira). A correlation analysis and relative gap were analyzed by statistical analysis between sales-based market share and interest-based market share. Besides, in the country-specific analysis, three major countries (USA, Germany, and France) were selected for market share analysis for Top 3 TNF-α inhibitors. As a result, significant correlation and similarity were identified by data analysis. In the case of Remicade’s biosimilars, the consumer interest in two biosimilar products (Inflectra and Renflexis) increased after the FDA approval. The analytical data showed that Google Trends is a powerful tool for market share estimation for biosimilars. This study is the first investigation in market share analysis for pharmaceutical products using Google Trends big data, and it shows that global and regional market share analysis and estimation are applicable for the interest-sensitive products.
