  • The purpose of this study was to examine the effects of chemical finishes on performance characteristics of microfiber blend fabrics. A 60% polyester microfiber /40% cotton blend woven fabric was finished by ten chemicals: three silicone softeners, one fluorochemical, and their mixtures. Performance characteristics examined were fabric hand attributes. Fabric hand was evaluated by instrumental measures using Kawabata KES-F system instruments. Silicone-only finishes did not change the bending properties significantly from those of the control fabric. The fluorochemical-only finish made the fabric stiffer and crisper. When the two chemicals were mixed they tended to offset this adversary effect. Most of the chemical finishes made the surface finer and smoother. Fluorochemical-only finish improved fabric strength. Likewise, dimethylpolysiloxane silicone improved fabric strength. Amino-functional hydrophilic and diamino-functional silicone softeners, on the other hand, reduced fabric strength. However, when mixed with the fluorochemical, the adversary effect was diminished.

  • 계기에 의한 진도산정은 보통 PGA와 진도와의 경험적인 관계식으로부터 계산되어 왔다. 그러나 일본 기상청은 지진에 의한 피해의 정도는 관측된 PGA보다는 진도와 상관이 더 크다는 점에 착안하여, 지진 계측기에 의해 실시간으로 진도를 산정(JMA 계측 진도)함으로서 지진재해를 좀 더 정확히 평가하는 방안을 채택하고 있다. 이 연구의 목적은 국내에서의 JMA 계측진도의 실제적인 활용방안을 제시하는 것이다. 한반도는 강진의 발생빈도가 낮기 때문에 사용할 수 있는 강진자료가 충분치 않다. 따라서 한반도의 지진원 특성과 감쇠특성에 맞는 강진동을 추계학적인 방법으로 합성하였다. 이러한 방법으로 합성된 강진자료에 대하여 JMA 계측진도를 포함한 6개의 공학적 지진동 상수들을 계산하였다. 다음으로 계산된 상수들 사이의 경험적인 관계식을 결정하였으며, 이 상수들을 몇 개의 그룹으로 분류하기 위한 군집분석을 수행하여 지진동 상수들을 분류하였다. 그 결과, JMA 가속도 ($a_0$)는 스펙트럼 진도와 유사한 그룹으로 분류되었으며, CAV(Cumulative Absolute Velocity)와는 비교적 관계가 먼 그룹으로 나타났다. JMA 계측진도는 지진재해 평가에 있어서 다른 하나의 평가척도로서 사용이 기능할 것으로 생각된다. 한편 지진재해의 예측에 활용이 가능한 PGA와 $a_0$에 대한 감쇠식이 모멘트 규모와 진원거리의 함수로 유도되었다.

Apparel manufacturers and distributors in China participated in the study. Random sampling method was used to collect the data. Data from 173 questionnaires were used for the statistical analysis. Descriptive analysis, factor analysis, Cronbach's alpha coefficient, t-test, and regression analysis were conducted. Two factors of private Guanxi were classified(i.e., affective Guanxi, instrumental Guanxi). Three factors of organizational relationship type were identified(i.e., opportunistic relationship, cooperative relationship, vertical relationship). The results indicated that distributors regarded affective Guanxi as important more than manufactures and employees regarded affective Guanxi and instrumental Guanxi as important more than presidents. Distributors regarded cooperative relationship as important more than manufactures. Employees regarded organizational relationship as important more than presidents. Affective Guanxi positively affected on cooperative relationship and vertical relationship but negatively affected on opportunistic relationship. Instrumental Guanxi positively affected on opportunistic relationship and vertical relationship. The result of this study may give valuable information to retail merchandisers and strategists who participated in fashion business in China.

  • Purpose : The aim of this study was to investigate the differences in sociodemographic characteristics, instrumental activities of daily living (IADL), and healthcare needs among disabled persons with and without language disorder. Methods : Using raw data from the National Survey of the Disabled Person (2017), this study compared 6,320 disabled persons without language disorder and 229 disabled person with language disorder among 6,549 persons with disabilities. The dependent variables included sociodemographic characteristics, IADL, and healthcare needs. Results : People with language disorder were younger (p<.001), illiterate (p<.001), and had higher family income (p=.003) than people without language disorder. In addition, people with language disorder had a higher disability grade than people without language disorder (p<.001), and the percentages of brain injury, hearing impairment, and intellectual disability were higher among type of disability (p<.001). People with language disorder showed significantly higher dependence on all items of IADL than people without language disorder (p<.001). As the first-ranked healthcare need, people without language disorder had the highest percentage of "chronic illness management," and people with language disorder had the highest percentage of "disability management" (p<.001). Conclusion : The findings of the current investigation suggest that health care services are needed to improve IADL in people with language disorder and that the development of a disability management program for people with language disorder is required.

  • Instrumental neutron activation analysis was used to measure the concentrations of 27 elements associated with respirable particulate matter (PM10) that were collected from the Third and Fourth Industrial Complex Area of Daejeon City. The distribution patterns of elements were clearly distinguished with their concentrations varying across more than four orders of magnitude. The mean for Al were recorded to be the highest value of 1,527 $ng/m^3$, while that for In showed the lowest value of 0.1 $ng/m^3$. If compared in terms of enrichment factors, it was found that certain elements (e.g., As, Br, Cl, Cr, I, In, Sb, Se, and Zn) are enriched in PM10 samples of the study site. The results of factor analysis indicated six factors with statistical significance, which may exert dominant controls on regulating the elemental concentration levels in the study area.

  • Purpose: This is a descriptive survey research study that identifies the intrapersonal, interpersonal, and organizational and community factors affecting the instrumental activities of daily living (IADL) in community-dwelling seniors. Methods: The study used data from a 2017 national survey of senior citizens, and includes 10,299 subjects aged 65 years or more. Complex sampling was performed to increase accuracy of the population, and hierarchical logistic regression was performed to identify the factors affecting IADL in seniors. Results: Amongst the organizational and community factors, we determined that the number of health centers, welfare facilities for senior citizens, hospital beds, and community sport facilities affected IADL in seniors, even after adjusting for intrapersonal and interpersonal factors. Conclusion: Helping seniors to maintain IADL independence for a longer duration is essential for their physical and social independence. Therefore, when establishing and developing policies for health promotion programs, efforts should be undertaken to actively reflect the level of IADL functions, and to create an accessible health and medical welfare environment by considering characteristics of senior citizens for operating programs.
