The purpose of the study was to investigate jean consumption among middle-aged Korean women and the characteristics of consumers as potential jean consumers. The data were collected from the survey of 238 Korean women aged 45 to 64 years old. The respondents prefer outlet store to other retail outlets and wear jeans mainly for travel, grocery shopping, and outing. The main reason for not wearing jeans is body change, which leads to poor fit in abdomen and waist area. The sample was clustered into two groups based on interest in jeans: high-interest and low-interest group. From the examination of group differences, the high-interest group rated conformity/brand reputation, scarcity, and attractiveness of appearance significantly higher compared to the low-interest group among the five clothing benefits pursued. No difference was found in obesity and body satisfaction. Group differences were found in recent purchase, price, number of jeans owned, and frequency of wearing jeans. The results suggest the characteristics of the potential jean market among middle-aged women in Korea. Implications are discussed.

A wide range of IoT applications use information collected from networks of sensors for monitoring and controlling purposes. However, the frequent appearance of fault data makes it difficult to extract correct information, thereby sending incorrect commands to actuators that can threaten human privacy and safety. For this reason, it is necessary to have a mechanism to detect fault data collected from sensors. In this paper, we present a trend-adaptive multi-scale principal component analysis (Trend-adaptive MS-PCA) model for data fault detection. The proposed model inherits advantages of Discrete Wavelet Transform (DWT) in capturing time-frequency information and advantages of PCA in extracting correlation among sensors' data. Experimental results on a real dataset show the high effectiveness of the proposed model in data fault detection.

The purpose of this study is to investigate trends of characteristics and changes in the field of marine/naval/underwater military science and technology in Korea. This study analyzed the keywords that appeared in marine/naval/underwater section of the "Journal of the Korean Military Science and Technology" during the period, 1998~2012. One hundred and seven articles were analyzed by keywords in English. Four hundred and fifty four keywords in English were analyzed by appearance frequency. Finally those results of source literatures and keywords were compared with each other and a better direction for the future of the field with further studies was suggested.

The purpose of this study was to identify aesthetic concepts of‘Sarangbang’furniture during the Yi-dynasty period and aesthetic descriptions indicating each concept expressed by experts in traditional furniture. The furniture selected for the study includes desks, table bookcases, document and stationary boxes (mungab), letter holders (Kobi) and inkstone boxes (younsang) with lacquer and oil finish on. The respondents were 72 traditional furniture experts; researchers collectors, sellers and artists related to period furniture. The important points of aesthetic descriptors were collected 123 from related literature. From experts' answers, 47 representative descriptors were selected. Data were analyzed with the SPSS using frequency, Percentage mean, factor analysis, t-test and C2. The results were as follows; 1. The aesthetic concept of sarangbang furniture during the Yi-dynasty can be categorized into 9 aspects; appearance of beauty, stability the interior space, naturalness, nobleness/harmony of lines, detail/refinement, simplicity, diversity solidity and surface division. 2. The characteristics of the Korean traditional furniture can be described using 47 descriptors explaining 9 concepts mentioned above.

The hemoglobin phenotypes and the gene frequencies of 223 Cheju native horses were studied by starch gel electrophoresis. The results obtained were as follows: 1. In the hemoglobin phenotypes, three phenotypes, HbAA, HbAa and Hbaa, which were controlled by two allelic genes. $Hb^A$ and $Hb^a$, were observed and their frequencies of appearance were 65.47%, 30.04% and 4.48% respectively. 2. The distribution of gene frequency was calculated as 0.805 in $Hb^A$ and 0.195 in $Hb^a$.

The purpose of this study was to develop wool knitted Jacket pattern suited for Middle-aged women's body shape. The usable data of first and second wearing test were coded for further statistical analysis including descriptive statistics(frequency and one way- ANOVA test, Student-Newman-Keuls Multiple Range Test) by using SPSSWIN 12.0. The results were as follows: 1. It was found that first evaluation for the appearance test on fitness, pattern B were better than the rest of them. 2. It was found that second evaluation for the test, jacket B with milano were better than the rest of them. Therefore, it should be designed as possible as considering the physical characteristics of knitted materials. 3. It was found that third evaluation for the test, it is necessary that knitted jacket follow a similar size tolerance such as a woven jacket.

In this paper the vibrational behavior of a multi-packet blade system having a cracked blade is investigated. Each blade is assumed as a slender cantilever beam. The coupling stiffness effect that originates from either disc flexibility or shroud is considered in the modeling. Hybrid deformation variables are employed to derive the equations of motion. The flexibility due to crack, which is assumed to be open during the vibration, is calculated basing on a fracture mechanics theory. In the paper, the results of the change in modal parameters due to crack appearance are presented. The influence of the crack parameters, especially of the changing location of the crack is examined.

Localized fat and cellulate have not only esthetic but health problem, they are treated by surgical or non-surgical method. There are elecro-acupuncture, ultrasound, radio frequency, endermologie, mesotherapy, and carbon dioxide therapy in prevalent non-surgical treatments. We reviewed the studies on them to analyze their seicntific evidence. The studies are not many. They reported good results of circumference loss or appearance improvement of histologic change but most of them have poor study design. Before marketing or using these modalities, it is ontcal to evaluate to their effectiveness through strict and scientific clinical trials.

The catalase phenotypes and the gene frequencies in erythrocyte of 223 Cheju native horses were studied by starch gel electrophoresis. The results obtained were as follows: 1. In the catalase phenotypes, three phenotypes, CatF, CatM and CatS, which were controlled by two allelic genes, $Cat^F$ and $Cat^S$, were observed and their frequencies of appearance were 24.21%, 47.53%, and 28.25% respectively. 2. The distribution of gene frequency was calculated as 0.480 in $Cat^F$ and 0.520 in $Cat^S$.

The study is to find out any significant relations in clothing behaviors according to attitudinal body image and plastic surgery attitude. The sampling method was a convenient sampling, and the subjects were 190 male and 160 female students in Daejeon. The survey was conducted from June 20 to July 15, 2008. The data were analyzed by the frequency analysis, Cronbach' ${\alpha}$, factor analysis, t-test and variance analysis. The subjects who pay much attention to weights and appearances have a positive attitude to plastic surgery. As they concern their body weights and appearance, they have high exhibition of clothing. Those who think their body as being attractive have been more interested in clothing and fashion. The subjects who have positive attitude for plastic surgery are more interested in clothing and fashion, showing higher conformity of clothing.
