Stockigt sizing test, which is readily affected by individual tester's bias as well as testing conditions in recognizing red coloration, had to be modified to improve its reliability and reproducibility. The novel testing system with the automatic recognizing program of red coloration was developed with the auxiliary equipments including an automatic liquid dispenser and a specimen shifter. The analysis program used a hue value of a droplet image in recognizing a point of time on red coloration instead of RGB values that are not similar to human perception of color. Hue was more sensitive in recognizing the red coloration of a droplet than the other two factors, Saturation and Value. During the test, the program records the time consumed up to a specific hue value of a droplet on a specimen. Differently from the conventional test, the automatic test could obtain a reliable and reproducible sizing degree with a minor error. Furthermore, the Stockigt sizing degree measured by the automatic system showed great correlations with contact angle and Hercules sizing degree. It means that such great correlations will contribute to the development of an integrated measuring system capable of predicting contact angle, surface tension, surface energy and Hercules sizing degree of paper and paperboards through the Stbckigt sizing test. It was meaningful to note that the automatic system for Stbckigt sizing test might be able to used to predict contact angle, Hercules and Cobb sizing degree, based upon the high correlation coefficients.

Objective: The aims of this study were to assess the direction and degree of lip-line cant in Korean adult orthodontic patients and to identify the effects of sex and age on changes in the cant severity. Methods: In this cross-sectional retrospective study, lip-line cant was measured in the frontal photographs of 585 Korean patients (92 men and 493 women) aged 18-48 years. The outcome variables (direction and degree of lip-line cant) were assessed in terms of predictor variables (sex, age, sagittal skeletal relationship, and menton deviation angle). Results: The direction of lip-line cant did not differ according to sex, age, or skeletal classification. Patients had $1.6^{\circ}$ of lip-line cant on average before orthodontic treatment. Middle-aged adults displayed a significant trend toward a lower degree of lip-line cant compared to younger adults (p < 0.01). Multiple linear regression analysis showed that the degree of lip-line cant was weakly negatively correlated with age (p < 0.001). Conclusions: While the direction of lip-line cant did not differ according to the parameters explored here, the degree of cant was correlated with age in adults, independent of menton deviation. Specifically, middle-aged adults tended to display significantly lower degrees of lip-line cant than did younger adults.

타이틀시퀀스에서 활용된 물질은 영화의 스타일과 내용을 포괄적으로 내포하고 있다. 그러므로 어떤 물질을 선택하는가에 따라 정서적 표현의 효과가 달라질 수 있다. 이에 따라 최근 20년간의 영화 타이틀시퀀스 42편을 수집하여 소재를 분류하고 기호학사각형을 이용해 물질의 범주를 정의하였다. 물질도의 강약을 검증하기 위해 설문하여 3단계의 물질도를 구분하고 영화의 장르에 따라 어떤 범주의 물질성이 활용되었는지 조사하였다. 분석 결과 물질성은 장르의 구분 없이 내용에 따라 선택되었으나 물질도의 차이는 있었다. 강한 물질도는 스릴러와 SF.미스테리 장르에서 사용되었고, 중간 물질도는 전반적으로 활용되나 특히 드라마 장르와 액션에서 활용되었다. 약한 물질도 또한 다양한 장르에서 활용되었으나 특히 공포, SF 미스테리 장르에서 활용되었다. 본 논문은 영화를 상징적으로 시각화하는 타이틀시퀀스 제작에 있어 물질의 선택에 의한 표현 방법 연구를 제안하였다는데 의의가 있다.

This study was conducted to compare the awareness, satisfaction, and usage patterns of female-consumers for food-nutrition labeling in Busan. The survey was conducted from April 15 to June 10, 2018 by questionnaire. Degree of perception of food-nutrition labeling was higher among individuals in their 30s, 40s and 50s than those in their 20s, 60s and 70s. The score of verification degree was highest among respondents in their 40s and lowest among those in their 20s and 70s. Degree of demand of individuals in their 70s was lower than that of those in their 60s. Degree of reliability of individuals in their 30s, 40s and 50s was higher than that of those in their 20s, 60s, 70s. Satisfaction degree did not differ significantly among groups. Overall the most common reason to review food labeling was 'to confirm expiry date' (30.8%). Among those in their 20s, the main reason for reviewing nutrition labeling was 'weight control', while it was 'nutrients' among those in their 30s, 40s, 50s, and 60s, and 'health improvement' among those in their 70s. Additionally, 51.3% of the subjects reported that the major reason for difficulty understanding the labeling was 'small letter, various form'. The demand for nutrient contents was highest in sodium. Age was negatively correlated with perception of food-nutrition labeling, demand, need for education and publicity, and nutrition knowledge (P<0.01), whereas it was positively correlated with dietary attitude (P<0.01). There was a strong correlation between demand for food-nutrition labeling and the need for education and publicity regarding food-nutrition labeling (r=0.546). Therefore, education materials and improvement plans based on age should be developed and implemented to inspire individuals to choose more nutritious food and develop a healthy dietary life.

The purpose of this study was to examine the residents' opinions on the degree of importance, and satisfaction with, the managerial service of multi-family housing. Residents' participation in managerial activities was also examined, because residents' opinions should be taken into serious consideration in order to improve the efficiency of housing management. Research methods used in this study were survey, field study, and content analysis of professionals' opinions. Survey data of 520 residents who live in multi-family housing were analyzed by means, frequencies, correlation, chi-square tests, t-tests, one-way ANOVA, post-hoc estimation (Scheffee test), and regression. The major findings of this study were as follows: First, many residents were dissatisfied with the quality of managerial service, but they thought that managerial services were very important. For example, they thought that safety inspection of the playground was very important, yet the current level of service was not satisfactory. Second, the characteristics of residents that determined the degree of residential satisfaction were income the location of the residence, and degree of participation in the community events. Third, the residents generally did not want to participate in the managerial services and community programs through such activities as participation in resident committee. In order to improve the housing management efficiency, residents' participation is critical. Some participants in this study pointed out that the details of management service and future plans need to be made public. New management models need to be developed to promote residents' participation and increase their satisfaction in the management.

We conducted this study to compare the awareness and attitude of Busan housewives about consuming marine products. The survey was conducted from April 10 to May 31, 2019 by using a questionnaire. The degree of preference of seafood was higher among individuals in their 40s than those in the other age groups. Among the women in their 30s, 40s, 50s and 70s, the reason for liking seafood was 'taste', and for those in their 60s it was 'nutrition'. Overall the most common reason for disliking seafood was the 'fishy smell (37.4%)'. Conception degree of nutritive value of seafood was higher among individuals in their 30s and 40s than that for those individuals in their 50s, 60s and 70s. As for the price of seafood, the wives over 40s thought seafood was more expensive than did those wives in their 30s. The younger the individuals were, the lower was the perceived degree of safety was 49.8% of the subjects reported that the main concern for purchase was 'freshness'. The perceived degree of safety for imported seafood was better for the wives in their 60s and 70s than that for those wives in their 30s, 40s and 50s. The confidence level for local Korean seafood was higher for the wives in their 60s than that for the wives in their 50s. The degree of preference for seafood was moderate overall, except for Jellyfish. Age was positively correlated with conception for safety and dietary attitude (P<0.01), whereas age was negatively correlated with monthly food expenditure, nutrition knowledge and intake requirements (P<0.01). Preference for seafood was positively correlated with conception for safety (P<0.05), nutrition knowledge (P<0.05), dietary attitude (P<0.01), awareness for nutritive value (P<0.01) and intake requirements (P<0.01). Laws and regulations should be reinforced in order to promote eating more seafood and periodic research to determine the actual amount of consumed seafood and people's preferences should be conducted.

Purpose - This paper examines how corporate social responsibility of the Korean retail industry affects the degree of asymmetric information. Recent theories predict that a firm's active engagement in socially responsible activities lowers the degree of asymmetric information of the firm. Research design, data, and methodology - This paper uses the sum of environmental and social scores (ES), published by the Korean Corporate Governance Service in order to proxy the degree of socially responsible management practices of Korean retail firms. This paper uses the ordinary least square method to investigate the above predictions. The publicly traded Korea retail firms listed in the Korean Exchange are analyzed from 2011 to 2016. To measure the degree of asymmetric information, this paper adopts the analyst dispersion and price impact measures. Results - This paper shows that the ES score has significantly positive relationships with these two measures of information asymmetry. The environmental score seems to increase the analyst dispersion measure and the social score appears to raise the price impact measure mores significantly. Conclusions - The results do not support the prior theory expecting a negative relationship between corporate social responsibility and the degree of asymmetric information. Environmental and social scores are found to affect the measures of information asymmetry differently.

The purpose of this study was to understand the preference of fashion materials according to the degree of consciousness and satisfaction of body. A survey was conducted using the randomly selected 439 woman students in the twenties. The consciousness variable had three levels which were lean, medium, and obese shape for each whole, upper and lower body with self-consciousness. Also, satisfaction variable had three levels which were satisfying, average, and unsatisfying group. We analyzed the data using analysis of correlation, crosstabulation analysis, and analysis of variance including Duncan multiple test. The results were as follows: 1) There was the positive correlation between height, leg, and arm length, and each variable, and the negative correlation between back, hip, thigh, waist, lower leg, ankle, and upper arm, and each variable. Also, we could observe the pattern that the larger the head or the more the weight was, the lower the satisfaction of body was. 2) There were no strong correlation between breast and hand size and each variable. From the crossed classification, we could observe the trend that the smaller the breast was, the lower the satisfaction of body was. 3) There were the strong correlation between whole and upper body in consciousness degree and between whole and lower body in satisfaction. 4) The consciousness of the whole body was shown lean shape 23.4%. medium shape 49.2%, and obese shape 27.2%. For the satisfaction degree of the whole body, satisfaction was shown 6.8%, average 41.7% and unsatisfaction 51.4%, so the satisfaction group is very small. 5) From the analysis for the consciousness degree of the whole body, the preferred fashion materials were polyester and acetate in casual wear, linen, polyester, acryl, T/W, and polyurethan in formal wear, and cotton, nylon, TIC, and T/W in sports wear. There was significant difference in casual wear, formal wear, and sports wear, but, not in underwear and accessories among he consciousness groups. 6) From the analysis for the satisfaction degree of the whole body, the preferred fashion materials were linen, silk, and acetate in casual wear, cotton in underwear, polyurethane in formal wear, and nylon in sports wear. There was the significant difference in casual wear, underwear, formal wear and sports wear, but, not in accessories among the satisfaction groups.
