Cosmetics is the product of culture that developed with the history of human civilization, and the cosmetics industry has made rapid progress in keeping with human desire for beauty and longing. In this study, preservative components essential for the safety and usefulness of cosmetics are currently used as solvents and moisturizers, and 1,2-hexanediol and octanediol components, which are reported to have no skin irritation even if the content is high, are compared to phenoxyethanol, which uses them as existing preservatives. To check the content of the preservatives substitute ingredient. Experimental formulation was applied to sheet mask formulation, hydrogel formulation and cream formulation. In conclusion, as preservative-free formula, 1,2-hexanediol 3.0%, octanediol 0.7% for cream type and octanediol 0.7% for sheet mask formula can be used. Also it would be possible to apply 1,2-hexanediol 2.0%, 2.5% and 3.0%, octanediol 0.3%, 0.5%, and 0.7% in general bacteria and yeast except fungi.

In modern society, economic growth and wealth of middle class nuclear families raised standards of living and concerns about qualities of consumption. Since child rearing in nuclear families is major concerns for them, spaces designed for children are emerging in commercial, cultural and entertainment spaces. However, not enough consideration is given to residential spaces where preschool children spend the most time. In preschool age, surrounding environment plays a very important role for children, interacting with them, facilitating balanced physical and mental development. This study aims to identify what elements preschoolers dream and desire in their residential space. During a class, seven years old children were told to freely draw a dream house they want to live in. In total 18 drawings by children, elements were categorized into natural, commercial, cultural, sports, entertainment amenities, decorative elements, and others, and their frequencies were analyzed. As a result, the demands for natural elements like gardens where they can personally grow fruits, vegetables, or flowers were the highest. The second highest demand were sports and entertainment amenities like swimming pools, trampolines, soccer fields. To summarize, dwelling needs of preschoolers in their sketches were high in natural elements, sports and entertainment amenities.

Influence of lighting on crime prevention is controversial, but many studies found increased lighting significantly reduced fear of crime. Since fear of crime in neighborhood is related to general well-being and reduction of physical activities of residents, it is crucial to increase the perceived safety in terms of the quality of urban life. However, the influence of various lighting characteristics on the perceived safety is largely unknown and evidence is trivial and weak. This study reviewed extensive researches regarding the influence of lighting on perceived safety in pedestrian environment, and tried to analyze the needs of research with the rapid change and development in lighting industry. This study selected 42 related articles through systematic review process, and categorized them into the groups according to the variables, types of environment, fields of research, methodologies, and objectives. Secondly, through empirical researches, the interaction between perceived safety and lighting characteristics(illuminance, uniformity, spectrum, color rendering, color temperature, distribution, etc.) is discussed. Experimental researches reveal the evidence that there is a limit of sufficient brightness for perceived safety, and within a certain effective spectrum the perceived safety can be enhanced using less energy. Further research is needed for LED light source considering mesopic vision, which is differed from traditional high intensity discharge lamps and measurement methods based on photopic vision. Also, perception of dynamic lighting should be studied with the development of intelligent road lighting control system. These findings can be a new standard for socially acceptable and effective public lighting to compromise the conflict between energy reduction and the perceived safety. Intervention studies show that it is not just quantitative ‘brightness’ that heighten the perceived safety, but it is a ‘message’ that the streets and districts are well-managed by local communities, which means aesthetic qualitative lighting design well-matched to each sites is also important.

The awareness of the nutrition labeling of 82 food producers and 668 government officials was assessed and compared, from May to June in 1994, to that of consumers. Compared to 82.4% of cosumers, 48.1% of producers and 47.8% of officials answered that nutrition labeling is necessary. 48% of producers expected a modest food price rise, but 70% thought food sales would not be affected with nutrition labeling. While being worried about the regulatory difficulties and the increased work load given the inadequate implementation of the current food labeling system due to insufficient personnel, 50.2% of officials wanted the new nutrition labeling system to be introduced within $1{\sim}2$ years. Contrary to the general dissatisfaction with the system and the lack of confidence in it on the part of consumers, producers thought that they currently provide sufficient food information for consumers, and that consumers had much confidence in it. Producers and officials were more found worried about consumers' inadequate understanding and inactive use of the system in contrast to the widespread and welcome support on the part of consumers. But it was fully agreed by all that education and awareness is crucial for the successful implementation of nutrition labeling system.

본 연구는 공개공지의 유형과 범죄두려움 영향 요인과의 관계를 파악하고, 이를 통해 공개공지에서의 범죄두려움을 개선하기 위한 방안을 알아보고자 하는 것이다. 이를 위해서 범죄 취약계층인 20~30대 여성을 대상으로 개인의 범죄두려움 정도와 범죄두려움 영향요인에 대한 인식, 그리고 대상 공개공지에서 느끼는 범죄두려움을 조사하였고, 이를 통해 다음과 같은 결론을 제시하고자 한다. 첫째, 공개공지의 유형(개방형 vs. 폐쇄형)에 따라 범죄두려움 영향요인 및 범죄두려움 정도에 차이가 있다. 둘째, 공개공지의 유형에 따라 범죄안전성 향상을 위한 환경 조성 시 시간 요인에 대한 판단을 다르게 하여야 한다. 셋째, 폐쇄형 공개공지는 공개공지 내부의 공간 구성 및 시설물의 특성에 따른 접근이 필요하다. The purpose of this study is to investigate how the type of public space affect fear of crime. For this purpose, I investigated fear of crime , disorder and ‘social control’ and asked about direct ‘fear of crime’. The results of this study are as follows. First, depending on the type of public space (open type vs. enclosed type), there is a difference in the level of fear of crime and factors affecting fear of crime. Second, depending on the type of public space, the decision on the time factors when creating an environment for improving crime safety should be different. Third, the enclosed public space requires access according to the characteristics of the space configuration and facilities inside the public space.
