Plasma is 4th state of matters, which consists of electrons, neutral, and ionized particles. In biomedical research, cold plasma, which is generated in atmospheric condition, has been applied to disinfect microorganisms such as bacteria and yeast cells. Because of its low temperature condition, the heat-sensitive medical device can be easily sterilized by the cold plasma treatment. In recent years, the effects of plasma on mammalian cells have arisen as a new issue. Generally, plasma induces intensity dependent necrotic cell death. In this research, we investigate the feasibility of cold plasma treatment for cancer therapy by conducting comparative study of plasma effects on normal and cancer cells. We use THLE-2 (human liver normal cell) and SK-Hep1 (human liver metathetic cancer cell) as our target cells. The needle type of cold plasma is generated by the Helium plasma device. Two types of cells have different onset plasma conditions for the necrosis, which may be explained by difference in electrical properties of these two cell types.

본 연구에서는 소프트웨어 제품을 개발하는 과정에서 보증기간을 고려하여 사용자에게 인도하는 시기를 결정하는 방출시기에 관한 모형의 비교 연구이다. 실증 비교 결과 지수화 소프트웨어 신뢰성장모형에서는 보증기간이 증가함에 따라 초기에는 최적방출시기가 증가했으나 점차 거의 유사한 방출시기를 나타내고 있으며 이와 반대로 불완전한 디버깅 소프트웨어 신뢰성장 모형에서는 초기에는 최적방출시기가 감소하였으나 보증기간이 길수록 소폭 증가하는 패턴을 보이고 있으며 제안된 극값모형은 점차적으로 증가하는 형태를 가진다는 결론을 도출 할 수 있다. 이러한 연구결과를 통하여 소프트웨어 개발자들은 보증기간과 방출최적시기의 관계를 파악함으로서 소프트웨어 개발 시 사전정보로 활용 할 수 있으리라 사료된다.

The purpose of this study was to examine the effects of science-based STEAM on creative thinking and creative personality. For this study the 3 grade, 2 class was divided into a research group and a comparative group. The class was pre-tested in order to ensure the same standard. The research group had the science class with science-based STEAM, and the comparative group had the class with teacher centered lectures for 5 months. The science-based STEAM was focused on finding stories in lifes, composition of knowledge, completion of knowledge. The results of this study are as follows. First, science-based STEAM was effective in creative thinking. Second, science-based STEAM was effective in creative personality. Also, after using science-based STEAM was good reaction by students. As a result, the elementary science class with science-based STEAM had the effects of developing creative thinking and creative personality. it means the science class with creative personality has potential possibilities and value to develop creative thinking and creative personality.

The accelerated convergence of automobiles and ICT has led to an increase in in-vehicle electronic devices designed to enhance the safety and convenience of drivers. Consequently, the information presentation on in-vehicle display systems for drivers and passengers need to be taken into account in order to guarantee driving stability while satisfying the needs of UX-based design users. This study compared and evaluated requirements for information items shown on in-vehicle displays regarding driving safety and convenience by groups according to driving career. A total of 38 information items related to safety and convenience that can be displayed while driving and pulling over were collected. Their level of necessity was tested and evaluated by 234 drivers. Using the results, we conducted a comparative analysis on the requirements for information presentation on in-vehicle display systems by groups according to driving career.

This research is aimed to examine the differences through comparative analysis of the Earth Science contents in the science textbooks between Korea and DPRK. The contents of level and scope in science textbooks between Korea and DPRK are analysed by TIMSS frameworks. The results of this research are as follows : 1. The science textbooks of DPRK is lower in quality of paper, printing to that of Korea, and the illustrations, editing design in the textbooks of DPRK are fewer, monochromic and monotonous while those in Korea. 2. The contents of Earth Science in DPRK's science textbooks rank 37.0%, but those of Korea's science textbooks rank 25.5% of the whole textbooks. The learning units related to Earth Science are generally similar to the level and scope in science textbooks between Korea and DPRK. The type of inquire activities in the textbooks of DPRK largely takes on the model experiment, and it was shown that the number of experiments directly made by children is very small compared to Korea' textbooks. 3. There are lots of differences in Earth Science learning terms and predicates used in the textbooks between Korea and DPRK.

As social media are emerging as essential communication channels for corporates in all areas, luxury jewelry brands have implemented enhanced strategies for brand story videos by creating brand channels on YouTube. In this study, a comparative analysis of the videos made available by Cartier and Tiffany&Co. on their YouTube Brand Channels was conducted, with the aim of identifying their strategic characteristics. The research method encompassed, both literature review and empirical investigations. A quantitative analysis was conducted by means of the 'HEART' model, a type of luxury jewelry brand story, and the following common strategic elements were identified. First, in their brand story videos both brands focus primarily on 'theme'. Second, 'relationship' and 'artisanship' are emphasized in addition to 'theme'. Third, the videos incorporate high level aesthetics to stimulate the fantasies and dreams of their audiences. The strategic differences between the brands are as follows. : First, 'artisanship' is given the greatest significance along with 'theme' in Cartier videos, while 'relationship' has prime significance in Tiffany&Co. videos. Second, a difference between a European approach and an American approach towards luxury brand building is evident, with Cartier hosting exhibitions while Tiffany&Co. provides gala videos instead.
