Middle-aged women, who are rising as the main consumers of modern society spare no cost in health care and enjoying cultural activities along with various changes in life styles. They are active in self-realization and taking care of their appearances, and the lifestyle changes of middle-aged women who prefer fashion of young and trendy sensibilities are becoming a important theme in the media such as dramas. The middle-aged women in dramas have social positions and economic power who contribute to the completion of the drama as a main character, and so their fashion styles are receiving attention. Also, they play the role of providing trend information and various fashion information, which even leads to sales of these fashion products. Hence, this study aims to derive design formative characteristics and fashion styles that current middle-aged consumers prefer and provide basic data for promoting the growth of the Korean fashion industry by analyzing the fashion styles in accordance with the life styles of middle-aged women in dramas who are becoming admired by middle-aged women. The analysis of the fashion of middle-aged female characters in dramas allows to examine the fashion styles per various situations in accordance with the life styles of middle-aged women, and furthermore in the domestic and foreign fashion industry, arranges an opportunity to form a new market for potential fashion exports aimed at foreign consumers who view Korean dramas.

The purpose of this research was to compare the effects of Danjeon Breathing exercise and walking exercise on physical fitness of middle-aged women. The Danjeon breathing exercise group(20) took health management counseling and performed an eighty-minute Danjeon breathing exercise three times a week for 12 weeks while the walking exercise group(25) took health management counseling and performed a walking exercise seven hours per week for 12 weeks. The control group(20) received only health management counseling. $VO_2max$, back strength, flexibility, balance, power and agility were measured using the Health Management System developed by the Korea Physical Science Institution. The collected data were analyzed by using the SPSS PC program and $x^2$, ANOVA, repeated measures of ANOVA and LSD. The result of this study are as follows: 1. There were significant differences on back strength, flexibility, agility and power among Danjeon breathing exercise group, walking exercise group and control group. The degree of back strength, flexibility and power of the Danjeon breathing exercise group was higher than that of the walking exercise group and the control group. The degree of agility of the walking exercise group was lower than that of the control group. 2. There were no significant differences on $VO_2max$ and balance among Danjeon breathing exercise group, walking exercise group and control group. In conclusion, Danjeon breathing exercise improves back strength, flexibility and power than walking exercise and walking exercise improves agility than Danjeon breathing exercise.

Purpose: This study was conducted to identify the relationship of health status, aging anxiety, social networking, generativity, and happiness and to investigate the main factors influencing happiness of late middle-aged adults. Methods: The study collected data from a total of 153 middle-aged men and women aged 50 to 64 years old from a consumer panel of Macromill-Embrain, the biggest online survey provider in Korea. The data were analyzed using descriptive statistics, Pearson's correlation coefficient and a stepwise multiple regression using the SPSS 22.0 program. Results: The subjects' happiness mean score was 16.17±9.29. Statistically significant differences in happiness were found according to education (F=4.38, p=.014), economic status (t=5.13, p<.001), and religion (t=2.18, p=.031). Happiness was correlated significantly with health status (r=.41, p<.001), aging anxiety (r=-.62, p<.001), family support (r=.43, p<.001), friend support (r=.36, p<.001) and generativity (r=.63, p<.001). The factors influencing happiness of late middle-aged adults were generativity (𝛽=.37, p<.001), aging anxiety (𝛽=-.35, p<.001), family support (𝛽=.20, p<.001), and economic status (𝛽=.13, p=.033). The explanatory power of the model was 58.0%. Conclusion: This study will be used as basic data when developing a nursing intervention program for successful aging by identifying factors that affect the happiness of late middle-aged adults.

Purpose : The purpose of this study was to investigate economic anxiety, self-efficacy, and financial stress levels in middle-aged male and identify factors affecting financial stress and provide baseline data for the development of nursing interventions to reduce financial stress in middle-aged male. Methods : Participants were 91 middle-aged male who live in Seoul and Gyeonggi Province. The data collection period was from April 1, 2020, to May 1. In this study, the questionnaire of economic anxiety, self-efficiency, financial stress was used. The data were analyzed by average, standard deviation, minimum, maximum correlation and regression using SPSS version 21.0. Results : In this study, the financial stress of middle-aged male affected economic anxiety with significant results (β=.628, p<.001). The absolute model's explanatory power was 36.8 % (adjusted R2=.368), indicating that economic anxiety affects financial stress levels in middle-aged male (F=27.151, p<.001). Conclusion : This study shows that economic anxiety affects financial stress. Based on the research results, basic data for the development and application of nursing programs to reduce financial stress were presented in consideration of the economic anxiety of middle-aged males. Therefore, there is a need for mediation to help middle-aged men positively recognize real-life situations and changes in society. Such mediation involves the development and application of educational and counseling programs that can reduce financial stress and economic anxiety in middle-aged men.

과학이 발전하면서, 인류가 사용할 수 있는 에너지의 종류도 점점 늘어나고 있다. 이들 대부분이 환경을 오염시키는 에너지이기 때문에 이 에너지를 계속 쓴다면, 환경오염이 점점 더 심각해질 것이다. 그러므로 본 논문에서는 환경을 덜 오염시키는 수력발전을 이용하여 발전하는 방법을 연구하고자 한다. 그 결과, 배수구에 장착사여 오폐수를 이용해 발전하는 수력발전기를 만들었다. 본 연구를 통하여 각 가정이나 저개발 국가에서 이 발전기를 사용할 수 있다는 점이 성공적이다.

본 연구에서는 설문조사를 통해 중학생들의 도형표현도 인지 능력을 알아보려 했다. 분석 결과 3가지 사실을 확인할 수 있었는데, 우선 과소추정 경향은 지수함수로 나타나며, 선기호, 사각기호, 원기호, 입체기호 순으로 과소추정 정도가 증가하였다. 둘째, 범례의 수(3, 5, 7개), 범례 표현방법(나열, 포섭), 기호 크기 척도 체계(비례적, 심리적)에 따라 기호의 크기가 상이하게 인지되고 있음을 확인하였다. 마지막으로 범례에 비해 기호의 크기를 과대추정 하는 경향이 있었고, 1학년과 3학년의 기호 인지 능력에서는 차이를 보이지 않았다.

$DF_{21}$ diesel locomotive was designed to satisfy the requirement of Kunming Meter track and the 2Co self-guided radial bogie was used to suit the complex curve track. There are totally 12 locomotives was served on the track. The first two locomotives were devotion running on the track since April 2003, the wheel tread splling was occurred on the middle wheel set of the two locomotives after running nearly 150 thousands km on the track of the two locomotives at August 2004. The dynamic analysis was carried out to find the reason. The wheel set longitudinal vibration resonance phenomenon was existed on the locomotive dynamic performance, and this was caused by the too big longitudinal stiffness of the journal box bar on the middle wheel set. Wheel set longitudinal vibration resonance maybe an important reason of lead to wheel tread spalling. The corresponding mend methods were put forward from the point of view of wheel set longitudinal vibration resonance. All the wheel tread of the 12 locomotives on the middle wheel set were in good condition and not occurred the wheel tread spalling after the mend till December 2007 after 350 thousands km were finished. The mechanism of the wheel tread splling and corresponding mend method was discussed in detail in this paper.

연구대상으로 삼은 중형 전기추진 무인기는 무게 18.5 kg, 날개 길이 6.4 m급의 저속 장기체공형으로 태양전지, 연료전지, 배터리를 전력원으로 사용한다. 이륙시간에 따라 태양전지의 에너지 총량이 달라지므로 체공을 최대화하기 위한 최적의 이륙시간을 선정해야 한다. 이를 위해 전압매칭을 통해 각 전력원을 선정하여 모델링을 수행하였으며 단품 성능시험을 통해 검증 후 시뮬레이션을 수행하였다. 이륙시간이 오전 6시, 오전 2시일 때 각각 최대 37.5시간, 최소 27.6시간동안 전력공급이 가능하였다. 배터리 SOC의 사용범위를 25~80%로 제한하도록 연료전지의 작동을 제어할 경우 각각 0.31시간, 0.63시간동안 더 전력공급이 가능하며 각 전력원은 최적 운전점에서 작동함을 확인하였다.
