Objective:In this study, we designed working clothes for livestock farmers to wear in spring and autumn to improve their work efficiency, conducted a physiological test on their performance, and evaluated their comfort. Background: In recent years, livestock farming in Korea has expanded, yet farmers' safety and sanitation levels remain low in hazardous environments that include organic dust, toxic gas, and heat stress, as well as the risk of accidents. Furthermore, most livestock farmers wear ordinary or dust-resistant clothes that are unsuitable for rearing livestock and compromise their safety and health. Thus, it is important to design specialized working clothes for livestock farmers that are comfortable and that minimize their health and safety risks. Method: To this end, we examined the literature on livestock (poultry, swine, and cattle) farmers' safety and sanitation issues, designed appropriate working clothes, and tested them in terms of sensory feel, physiological response, and subjective comfort. Results: The respondents expressed satisfaction with the new working clothes. The results of a physiological test showed a decline in temperature and humidity inside the clothes, a lower pulse rate, and a lower oxygen intake compared to the measurements taken when famers wore their previous working clothes. This indicates a fall in heat stress and fatigue, which was mostly consistent with the results of the assessment of subjective comfort. Conclusion: The results of the analysis show an improvement in the comfort of the new working clothes compared to the dust-resistant clothes that are widely worn. Based on this study, the new working clothes need to be further tested and evaluated to improve the design. Application: This study is expected to contribute to designing better working clothes for livestock farmers.

Objectives: Kinesiology tape (KT) creates a pulling force on the skin, thus improving blood and lymph flow by alleviating hemorrhage and congestion of lymphatic fluid. The authors hypothesized that the use of KT could be beneficial for the management of complications after head and neck surgery and designed this study to evaluate the effects of KT on swelling, pain, and trismus after enucleation of mandibular dentigerous cysts with third molar extraction. Materials and Methods: Forty patients who underwent enucleation of a dentigerous cyst with extraction of the mandibular third molar were selected. The patients were randomized into two groups (n=20 each): a KT group, where KT was applied after surgery in addition to basic postoperative care, and a control group, where patients received basic postoperative care without KT application. Swelling, pain, and trismus were evaluated before surgery (T0) and on postoperative days 1 (T1), 2 (T2), and 3 (T3). Cyst volume, gauze weight for assessing bleeding, and operation time were recorded. Results: There was a significant difference between the two groups in the change in swelling up to T1 and the change in swelling between T1 and T2. The maximum swelling in the KT group was significantly less than that in the No-KT group and maximum swelling appeared faster in the KT group than in the No-KT group. Both groups showed a mild pain response but there was no significant difference between the two groups. There was no significant difference on interincisal distance change between the two groups. There were no correlations between cyst volume, bleeding, operation time, and maximum swelling. Conclusion: KT can effectively manage facial swelling after oral and maxillofacial surgeries such as cyst enucleation and third molar extraction, thus improving postoperative patient satisfaction levels and quality of life.

Family instability has a negative effect on not only an individual household but also the society. The government continues to operate family support centers as a countermeasure to family instability issues. A healthy and multicultural family support center is considered an effective support system that extends from a family unit to the local community. In this study, the satisfaction and demand levels of each center, located in Seoul and Incheon, were examined with respect to items such as operation contents, physical space, and organizational structure. The results showed that various efforts for creating a family-friendly community were implemented in healthy family support centers and multicultural family support centers. It was found that the center organizers and operators focused more on software and programs than on the physical environment. There was mostly a shortage of physical and environmental space. This space shortage limited the planned and ongoing activities in terms of the residents' self-directed participation and space formation for a family-friendly educational culture. Therefore, it was necessary to set up the space-related criteria for each center in order to solve this environmental issue. We identified the baseline data of the criteria for a center's physical and spatial design and size. In particular, it was suggested that a more strategic physical and spatial design is needed to achieve an integral and effective operation for the connection of the family with the local society.

The purpose of this study was to identify egocentrism, self-consciousness, and body cathexis between Boys' and Girls' high school students. It helps us to understand them. Also we investigated the correlation between psychological characteristics and clothing behavior of high school students. The questionnaire were administered to 630 boys' and girls' high school students living in Jinju, Gyeongnam, and the data were analyzed by Frequency, Factor Analysis, Pearson's Product Moment Correlation, ANOVA, Multiple Regression Analysis and Duncan test. Egocentrism of high school boys and girls showed middle levels of mean and distribution, and sympathy was the highest at coeducation high School whereas a sense of justice was the highest at boys' high school. Self-consciousness was high level at both boys' and girls' high school, but public self-consciousness was higher than personal one. Both of them were higher in girls' than in boys'. Also body satisfaction was a little high and boys satisfied with their faces, busts, and whole body more than girls. There were significant differences among dressing for others, clothing interest, psychological dependence, exhibition except conformity. Girls have dressing for others, clothing interest, and exhibition more than boys. There were significant positive correlations among dressing for others, clothing interest, psychological dependence, and conformity whereas exhibition was negatively related to clothing behavior. Public self-consciousness, appearance, and popularity were the most influential variables to dressing for others. Also gender was proved to be one of the most influencing factors on students' clothing behavior.

Product developers nowadays must consider not only the technological satisfaction of consumers but their affective needs as well. These affective needs are greatly affected by the appearance and performance functions of the product, which are simply called in this study appearance-based affection and performance-based affection. This study examined these two affective factors that must be considered while designing mobile phones. Extracted relationship between the two factors was processed in five steps. The first step includes gathering potential affective expressions that are needed to evaluate the levels of consumer's affection for mobile phone design in the pool of adjectives. In the second step, a simple frequency analysis was done from a consumer survey to extract frequently used affective expression. The third step was to extract primary tasks for mobile phones and to perform an experiment or a survey for the evaluation of mobile phones using those tasks. Representative affective factors were then extracted in the fourth step based on factor analysis. Finally, using ANOVA, the extracted representative affective factors were prioritized to draw a relationship between appearance-based affection and performance-based affection. The result of this study suggests each of appearance-based affections and performance-based affections that should be considered in designing mobile phones.

Research has been conducted to examine the effects of mechanical and sound characteristics of fabrics on affective quality. The present study developed the Affective Quality Evaluation and Estimation System for Textiles (AQEEST) with distinguished features that can be effectively used in the affective research of fabric frictional sound. The AQEEST consists of three subsystems (affective quality evaluation, affective quality estimation, and audible distance estimation subsystems) and each subsystem consists of three to four modules (e.g., evaluation condition setup, evaluation experimentation, and textile database management modules) depending on its functional requirements. The affective quality evaluation subsystem was designed to help administer an experiment in a systematic manner and present acoustic and visual stimuli simultaneously in various gait conditions (walking, jogging, and running) to mimic a more realistic situation of textile frictional sound production. Next, the affective quality estimation subsystem was designed to estimate the sound characteristics, affective qualities, overall psychological satisfaction, and reference cluster of a textile using its mechanical and/or sound characteristic information. Lastly, the audible distance estimation subsystem was designed to estimate the just noticeable sound pressure levels and audible distances of a textile for various gait conditions using its mechanical characteristic information. The AQEEST can be upgraded by accommodating more affective quality study results for various textiles.

Quality has been a key issue to manufacturers. Many distinguished scholars have defined quality with profound insight. Korean firms struggle to make better products to fulfil requirements and satisfy customers. Korean industries have implemented quality management from Japan in early 70s. Statistical quality control, QCC (Quality Control Circle), and total quality management have also been introduced in succession. Chief executive officers, managers, and field employees have been aware of the importance of quality since then. This quality movement force workers to improve quality. They have to maintain the quality of products and compete with foreign products. Korean industries were able to compete with foreign industries in price. However, Korean firms now have to compete in quality as well as price. ISO (International Organization for Standardization) was established and industries around world have started to implement standardized systems depending on their need. ISO 9000 has continuously been revised and firms around world started to register a ISO 9000 certificate. Today's quality competitiveness gets more deeply involved. KSA (Korean Standard Association) have launched QCAS (Quality Competitiveness Assessment System) since 1997. Up until now recent status of QCAS have been reported but the characteristics of QCAS results have not been analyzed. In this article we examine the QCAS results of 41 firms in 2014. QCAS consisted of 13 subsections : strategy and management system, organization culture and development of human resource, information management, quality system, customer satisfaction, management achievement, TPM, logistics, product development and technology, PL, QCC, SQC/SPC, and reliability. We performed one way ANOVA to discover the difference among the levels of firm size, business type, and quality hall of fame using the total scores of 13 subsections resulted from QCAS. We also analyzed the scores of 13 individual subsections of QCAS to see if there is any differences based on firm size and business type. We interpret the results and implication of analysis and finally draw a conclusion.

Recently, the rapidly growing new generation of renewable energy projects has emerged as an artificial building that creates a mix of natural environments and disruption to the environment. It serves as a quality inhibitor for rural landscapes and implies the absence of favorable rural landscape. Therefore, the study looked at the color scheme of residents, visitors, and experts in the village, which changed the color of the landscape, and analyzed the color scheme of residents, visitors, and experts. In order to do so, the village was divided into three types and conducted a survey by the general public and experts. In the case of the survey, residents of the three districts (Yeoju, Dam yang, Jeju) were surveyed for 210 residents, and the survey conducted a survey and analysis of 30 people in the area. As a result, both the general public and experts recognized the color change in the energy business, which resulted in the identification of associations and colors of the village. In addition, the recognition and satisfaction of the current situation showed that the education programs for the public were more important than the professionals, as the public show ed low levels of public awareness. Based on this research, we expect to be able to utilize the plan as a guideline for the project of installing solar panels, which is expected to be implemented in the beginning of the project, and can be used as a guideline for the establishment of the solar panels.

본 연구는 커뮤니케이션 능력이 자율성, 관계성, 그리고 생활만족도를 매개로 자기제시 성향에 미차는 영향을 구조방정식 모형을 통해 검증하였으며, 나아가 각 변인들 간의 관계가 남녀 집단에서 어떠한 차이를 보이는지를 분석하였다. 전체집단에 대한 가설모형의 적합도는 높게 나타났으며 잠재평균분석 결과 관계성은 여성이 남성에 비해 높은 것으로 밝혀졌다. 또한, 커뮤니케이션 능력과 자기제시 성향의 인과구조는 성별에 따라 차이가 존재하는 것이 발견되었다. 남녀 비교를 위해 다집단 분석을 실시한 결과, 여성 집단의 경우 커뮤니케이션 능력이 높을수록 자기제시 성향이 높았다. 남성 집단에서는 자율성과 생활만족도가 자기제시 성향에 부적인 영향을 미쳤고 관계성이 자기제시 성향에 정적인 영향이 있는 것으로 드러났다. 이를 통해 커뮤니케이션 능력과 자기제시 성향은 단순한 인과적 관계를 가질 뿐 아니라, 남성의 경우에는 개인의 내재적 동기에 의해서 상호작용 방식이 달라진다는 잠을 알 수 있다. 한편, 잠재변인 간의 구조적 관계는 관계성이 자기제시 성향에 영향을 미치는 경로를 제외하고는 남녀 집단에서 동일하게 나타났다.
