This research is in search of the new criteria of market segmentation for Korea motorcar market. This market was usually segmented by price and basic demographics such as age, education and job and so on. In order to develop new criteria, we discuss also about some traditional segmentation methodologies and propose more effective method for this type of approach. Main topic of this research are as follows; We develop criteria which are made up of a lifestyle and demographics both. Quantitative criteria were mainly used up to the present, for it is easy to interpret and recalcurable. We are tring to mix quantitative and qualitative criteria instead, for this is more implicable and suggestive, besides also remeasurable. Using these types of segmentation criteria, we found 3 sub market segmentations such as 1. mental value oriented group which is mainly originated from white color, 2. conservative value oriented group which is mainly originated from housewives, 3. modern and new generation value oriented group which is mainly originated from specialists. Each group has different needs for car, we can build totally new market segmentation strategy for Korea motorcar market. This fact itself also suggestive in view of a concrete market analysis. We develop each group's ideal car concept positioning. Compared with old existent market segmentation, this type of approach based on lifestyle and demographics will give an intuition that is qualitatively more affluent and quantitative more stable.

여름이 다가오면 물놀이를 가는 인원이 많이 증가할 수밖에 없고 물놀이를 하다 보면 피치 못하게 인명사고가 날 수도 있다. 이러한 인명사고는 어린이들에게 더욱 쉽게 발생하기 마련이다. 고로, 어린이들의 물놀이 안전사고를 예방하기 위하여 아두이노를 활용한 스마트 어린이용 구명조끼를 제작하여 안전한 물놀이 문화 정착과 어린이들의 물놀이 안전사고를 예방할 수 있다. 본 논문에서는 아두이노를 이용하여 어린이용 스마트 구명조끼를 설계하고 구현하였다. As summer approaches, the number of people going to the water will inevitably increase, and playing in the water can inevitably lead to casualties. These casualties are more likely to occur in children. Therefore, in order to prevent children"s water safety accidents, smart children"s life vests using Arduino can be manufactured to establish a safe water play culture and prevent children"s water play safety accidents. In this paper, a smart life jacket for children was designed and implemented using Arduino.

Background: Postoperative urinary retention (POUR) is a common complication after total knee arthroplasty (TKA) and associated with the use of anticholinergics. The introduction of sugammadex has decreased perioperative use of anticholinergics. Since anticholinergics may influence the detrusor muscle, the purpose of this study was to compare incidence of POUR between sugammadex and anticholinergic use for reversal of muscle relaxant. Methods: This study was a retrospective cohort study in a university-affiliated hospital. A total of 571 patients who underwent TKA between 2015 and 2016 with an American Society of Anesthesiologists class ≤ 3 were included in this study. Patients who received sugammadex (group S, n = 208) were compared to those who received glycopyrrolate with pyridostigmine (group C, n = 363) for reversal of neuromuscular blockade. The primary outcome was the incidence of POUR. Secondary outcomes were hospital length of stay (HOS) and daily residual urine drained from intermittent catheterization. Demographic, intraoperative, and laboratory data were collected. Results: The incidence of POUR was significantly lower in group S compared to group C (36.1 vs. 48.8%, P = 0.003). On post-operative day (POD) 0, there was no significant difference in the residual urine volume between the two groups. However, from POD 1 to POD 4, the residual urine volume was significantly lower in group S compared to group C. There was no significant difference in HOS between the two groups. Conclusions: The use of sugammadex was associated with a lower incidence of POUR by avoiding glycopyrrolate in patients underwent TKA.

This study intends to suggest the marketing strategy plan based on the understanding of the elements that influence consumers` motivation of selecting a beauty shop by investigating the effect of esthetic desire and consumer culture on the motivation of selecting a beauty shop. To perform this study, 314 questionnaires were distributed from December 20, 2012 to January 27, 2013, targeting customers who use beauty shops located in Gyeonggi, Pocheon, Uijeongbu for practical survey, and final 294 sets were used as analysis data. Frequency analysis, factorial analysis, reliability analysis, and multiple regression analysis were implemented on the collected data by using SPSS 20.0 statistics program. The results according to study subjects of this study are as follows. First, to investigate demographic characteristics of research subjects, most of them are in the income around KRW 1,000,000∼2,000,000 monthly average and the housewives in their 40·s having high school diploma. Second, as the result of investigating the dimension of esthetic desire of research subjects, 5 elements, e.g. appearance improvement type, refreshing oneself type, change seeking type, emotion satisfaction type, and indifference type, were deducted. Third, as the result of investigating the dimension of consumer culture of research subjects, 3elements, e.g. conspicuous consumption, premeditated consumption, and economizing consumption were deducted. Fourth, as the result of investigating the motivation dimension of choosing a beauty shop on research subjects, 3 elements, e.g. shop environment, shop reputation were deducted. Fifth, as the result of investigating the effect of esthetic desire on the motivation of choosing a beauty shop, statistically meaningful affirmative effect appeared. Sixth, as the result of investigating the effect of consumer culture on the motivation of choosing a beauty shop, statistically meaningful affirmative effect appeared. Salon marketing strategies considering esthetic desire and consumer culture can be suggested as follows. First, in order to secure customers` parking convenience, it is necessary to build a business cooperative relationship with neighborhood business street which has a wide and pleasant parking space. Second, new customer creation can be expected through word of mouth effect by making distinct features in rest space. Third, it is necessary to establish a system to minimize customers` waiting time. These marketing strategies are considered to be able to secure advantages in customer acquisition, and it is hopeful that the research on the understanding of elements that influence the motivation of choosing a beauty shop are to be performed from various angles.
