The purpose of this study is to develop a bodice pattern drafting method for Korean elderly women over sixty years old on the basis of their physical characteristics which differ from those of adult women. The study is composed as follows; 1. One hundred and five elderly women were measured on 20 items. Twenty-five items including 20 measured items and 5 calculated items were analyzed statistically. 2. A new method was developed based on the results of data analysis. Basic shells constructed from the patterns were examined through three fitting tests for completion. 3. The sensory evaluation was applied to evaluate the new pattern for elderly women by comparing it with the conventional pattern for adult women. A five-point rating scale was developed for the evaluation. According to a statistical analysis of the result of the 20 items on the questionnaire, all the items showed significant differences (a$\leqq$0.01) between the two, with the new pattern having higher scores.

The 2018 local elections completely upended the composition of Busan's city council, with the council membership changing from being solidly and consistently conservative to being over 80% liberal. What explains this anomalous outcome? While existing literature suggests the outcome of the 2018 city council elections was the consequence of a combination of structural and strategic factors, such as the decline of regional voting, we argue that the individual-level evaluation of President Moon Jae-in is one of the primary factors driving this result. Although coattails effects are commonly considered in concurrent national legislative elections, the Presidentialized and nationalized politics of Korea makes it possible for Presidential elections to affect local elections as well. We assess our explanation through an analysis of repeated cross-sectional survey data collected just before the 2018 local elections. The results of the analysis show that support for the Democratic Party is very strongly predicted by individual-level evaluation of President Moon. When considered in the context of the timing of presidential and local elections, the results suggest that Presidential coattail effects are capable of destabilizing established political patterns, such as regional voting, if perhaps only in a sporadic and idiosyncratic fashion, depending on whether or not local elections are held early on in a President's term.

Generally, cosmetic creams have been used to moisturize and smooth human skin. Recently, people concerns about the creams released with natural flavors and its functionality. This study focused to assess the psychophysiological effects of creams with 5 natural flavors such as patchouli oil, frankincense, sandalwood oil, none and newly developed S6. Initially, we have performed subjective evaluation for 100 female subjects aged 20 to 30 from Daejeon, South Korea. The results showed the most preferred flavor was S6 condition. Second, physiological evaluations for 20 female subjects were measured with EEG, ECG and GSR. In EEG analysis, the alpha ratio was confirmed to appear higher in each condition. The statistical analysis shows that significantly largest effect at S6 condition($p$ <0.05). The result from ECG and GSR measurements also shows the same trend. Third, skin conditions were measured when using S6. As a result, the skin temperature, humidity and skin movement speed were increased with S6 condition. The moisturizing and elasticity effects were confirmed.

This study suggests an effective online guide for foreign teachers who want to teach English in Korean schools. When designing this guide for overseas applicants, there should be a consistent analysis to reflect the process of the system. Thus, this paper provides an analysis and results for an integrated online guide to increase the efficiency based on the pedagogical framework for analysis of the 'ADDIE' model (Analyze, Design, Development, Implementation, and Evaluation). The number of job applicants who wish to teach English in Korea is growing rapidly because Korea is one of the fastest growing economies in the world and the 'Korean Wave' has especially been experiencing significant changes with the development of social network services and digital technologies. As a result, overseas applicants' expectations regarding Korea when they are seeking information and applying is very high, but the aspects of the procedure provided by the government are somewhat disappointing. The paper presents customer needs and specific recommendation for each step of the application process to improve the guide's effectiveness.
