The purpose of this study is to provide basic data for the development of UV protection products using natural materials. The research method is investigation and analyzation of the current status of the domestic and foreign industries, natural material research trends, and patent status of skin care-related sunscreen. As the result of the study, the U.S. market for sunscreen is the largest one, accounting for about 21% of the world, and the Chinese market is rapidly growing. The top four major types of functional cosmetics in Korea are complex functional products, followed by wrinkle improvement, sunscreen and whitening, and both the global and domestic markets continue to grow continuously. Over the past decade, research trends in natural sunscreen materials have shown that Scutellaria baicalensis, Humulus lupulus L., licorice, Finger root, Green tea, lespedeza cuneata extracts are effective, and in addition, they are also effective in photo-aging, antioxidant, anti-inflammatory, antibacterial, whitening, and wrinkle improvement. The patent registration status is on the rise and the ingredients were secured from plants and seaweeds. As the conclusion of this research, It is expected that natural UV protection material will be able to be used as multi-functional cosmetics material by developing safe and proven natural materials in line with future global trends.

최근 딥테크 및 글로벌 스타트업들의 기술경쟁력 제고를 위한 국가적 지원이 증대함에 따라 원천기술을 보유한 기술창업 건 수역대급으로 증가하고 있는 추세이다. 기술 기업들은 사업의 다각화 및 글로벌 진출에 유리하다는 장점이 있으나, 이들의 전략 성공을 위해서는 체계적인 인큐베이팅 및 자금유치는 필수적이라 할 수 있다. 본 연구는 첨단 가술스타트업의 투자유치성과에 중요하게 여겨지는 요인들이 IT 및 BT 산업별로 어떻게 다르게 영향을 미치고 있는지를 연구하는 목적으로 하고 있다. 선행연구에 따르면 기술 스타트업에 대해서는 그들이 보유한 기술 역량(특허), 창업자/팀의 능력, 제휴 등을 중요한 자원으로 보고 있으며, 이는 기업의 퀄리티를 차별화하는 신호로 작용하여 투자유치에 긍정적 영향을 미치는 것으로 나타났다. 본 연구에서는 국내 기술 스타트업의 산업별 차이에 따라 기술 스타트업의 특성이 투자유치성가에 미치는 영향을 비교분석하고자 한다. 본 연구는 2022년 기준 서울시 창업지원시설에 입주한 스타트업 122개사를 대상으로, 전 산업을 대상으로 한 회귀분석모델과 글로벌 산업기술 분류 기준에 따라 구분된 BT 및 IT 산업만을 대상으로 한 회귀분석 모델을 설정하여 연구목적을 규명하고자 한다. 본 연구 결과는 국내 기술스타트업의 투자유치 의사결정에 대한 실증분석을 통하여 기존 이론을 검증하였다는 것에 의의가 있으며, 산업별로 투자유치에서 중요하게 고려하는 요소들이 다르게 작용할 수 있음을 밝히고 산업별 특성에 따라 투자유치 시 실질적으로 필요한 요소들을 제시한다는데 실무적인 시사점을 지니고 있다.

Academia and research institutes mainly use qualitative methods that rely on expert judgments to understand and predict research trends and science and technology trends. Since such a technique has the disadvantage of requiring much time and money, in this study, science and technology trends were predicted using keyword network analysis. To that end, 13,618 AI (Artificial Intelligence) patent abstracts were analyzed using keyword network analysis in three separate lots based on the period of the submission of each abstract: analysis period 1 (January 1, 2002 - December 31, 2006), analysis period 2 (January 1, 2007 - December 31, 2011), and analysis period 3 (January 1, 2012 - December 31, 2016). According to the results of frequency analyses, keywords related to methods in the field of AI application appeared more frequently as time passed from analysis period 1 to analysis period 3. In keyword network analyses, the connectivity between keywords related to methods in the field of AI application and other keywords increased over time. In addition, when the connected keywords that showed increasing or decreasing trends during the entire analysis period were analyzed, it could be seen that the connectivity to methods and management in the field of AI application was strengthened while the connectivity to the field of basic science and technology was weakened. According to analysis of keyword connection centrality, the centrality value of the field of AI application increased over time. According to analysis of keyword mediation centrality during analysis period 3, keywords related to methodologies in the field of AI application showed the highest mediation value. Therefore, it is expected that methods in the field of AI application will play the role of powerful intermediaries in AI hereafter. The technique presented in this paper can be employed in the excavation of tasks related to regional innovation or in fields such as social issue visualization.

This paper presents study on technological forecasting of Next-Generation Display technology. Next-Generation Display technology is one of the emerging technologies lately. So databases on patent documents of this technology were analyzed first. And patent analysis was performed for finding out present technology trend. And the forecast for this technology was made by growth curves which were obtained from forecast models using patent documents. In previous study, Gompertz, Logistic, Bass were used for forecasting diffusion of demand in market. Gompertz, Logistic models which were often used for technological forecasting, too. So, two models were applied in this study. But Gompertz, Logistic models only consider internal effect of diffusion. And it is difficult to estimate maximum value of growth in two models. So, Bass model which considers both internal effect and external effect of diffusion was also applied. And maximum value of growth in Gompertz, Logistic models was estimated by Bass model.

기술추세분석(trend analysis)이나 특허분석(patent analysis) 등과 같이 객관적 자료를 이용하는 여타 기술예측방법과 달리, 델파이 방법은 해당 분야에 대한 전문가들의 식견(또는 주관적 평가)을 예측의 유일한 원천으로 하고 있다는 점에서 예측결과에 대한 신뢰도 분석을 강하게 요구하고 있다. 이러한 점에 착안하여 본 연구에서는 최근에 실시된 산업기술예측(1998) 자료를 이용하여 델파이 방법을 이용한 기술예측의 신뢰도 분석을 실시하였다. 이러한 분석은 전문가들의 예측결과에 대해 내적 일관성의 유지 여부와, 전문도가 상이한 집단간에 예측 결과의 차이가 있는지 여부를 중심으로 이루어졌으며 그 결과는 다음과 같다. 첫째, 응답 결과에 내적 일관성이 있는지 여부를 검정한 결과 생물·정밀화학분야를 제외한 모든 분야에서 일관성을 지니고 있는 것으로 나타나고 있다. 두번째, 전문도가 높은 응답자들일수록 자신의 예측결과를 확신하고는 있으나, 전문도가 낮은 응답자들에 비해 예측결과에 이견이 큰 것으로 분석되었으며, 마지막으로 전문도가 높은 응답자들과 그렇지 않은 응답자들 사이에 기술과제의 예상 실현시기에 대해서는 거의 차이가 없는 반면, 합의(consensus)의 정도는 큰 차이가 있는 것으로 나타났다. 이러한 분석결과는 델파이 방법을 이용한 기술예측을 설계하는 데 있어 몇가지 시사점을 제공하고 있다. 첫번째로 기술예측시 전문가들의 예측결과에 대해 내적 일관성이 존재하는 지 여부를 검증할 수 있도록 예측과정을 설계하는 것이 바람직하다는 것이다. 이러한 설계과정은 델파이 방법이 예측결과를 검증할 만한 객관적인 장치를 지니지 못하고 있다는 점에서 더욱 필요하다고 하겠다. 두번째는 정보로서의 가치가 큰 전문도가 높은 응답자들의 예측결과를 활용하기 위해서는, 예측결과에 대한 이들의 합의(consensus)의 정도를 높일 수 있는 방안이 마련되어야 한다는 것이다. 델파이의 최종 라운드가 진행된 이후 이들에 대해서만 추가적인 라운드를 실시하거나, 예측과정에서 이들에게 관련 정보를 제공하는 것도 하나의 대안이 될 수 있을 것이다.

In this review, the use of air bubbles in the pharmaceutical and cosmetic formulations was discussed. The foam bubbles show different characteristics depending on the foaming agents and foam generating devices. The foam bubbles are generated in the form of dispersion of gas bubbles in a solvent. The assessment of stability and rheological properties of bubbles are the starting point for the formulation to be used. Pharmaceutical and cosmetic uses of bubbles are substantially growing, and the foam formulations of drugs can be used for rectal, vaginal, and dermal symptoms. The foam formulation is used in hair mousse, makeup foundation, and sunscreen cosmetics in basic cosmetics. Recently, a lot of studies and patents have been filed in stabilization of active ingredients and delivery of the active ingredient in terms of foam formulations. In the future, foam formulations are expected to be used as novel cosmeceutical formulations.
