Background: Occupational pesticide exposure is a potential risk for respiratory health effects. Most clinical studies on pesticide exposure were related to acute exposure, and only a few studies on chronic exposure have been conducted. This study investigated the chronic respiratory health status and the chronic effects of occupational pesticide exposures of farmers in Gyeonggi-do. Methods: Surveys and pulmonary function tests were conducted on 1,697 farmers in 16 regions of Gyeonggi-do. The structured questionnaire included demographic characteristics, medical history, recent respiratory symptoms and diseases, and work-related conditions, and was conducted through one-on-one interviews. The prevalence of respiratory diseases was compared by the odds ratios (ORs) at 95% confidence intervals (CIs) estimated by logistic regression analysis. Additional multivariate logistic regression analysis was also conducted. Results: Pesticide work groups showed significant association with an obstructive pattern in the lung function test (unadjusted OR, 2.38; 95% CI, 1.17–5.52). Selected work-related variables of pesticide exposure were ‘start age,’ ‘cumulative duration,’ ‘mixing pesticides,’ and ‘protection(goggle).’ The obstructive pattern of lung function test showed significant associations with mixing pesticides (OR, 2.30; 95% CI,1.07–5.46), and protection (goggle) use (OR, 0.34; 95% CI, 0.12–0.79). Conclusions: Mixing two or more pesticides showed a significant association. Wearing goggles can be seen as an indicator of awareness of the protective equipment and proper wearing of protective equipment, and loss of pulmonary function can be prevented when appropriate protection is worn.

Mitophagy : Therapeutic Potentials for Liver Disease and Beyond
Sooyeon Lee,Jae-Sung Kim 한국독성학회 2014 Toxicological Research Vol.30 No.4
Mitochondrial integrity is critical for maintaining proper cellular functions. A key aspect of regulating mitochondrial homeostasis is removing damaged mitochondria through autophagy, a process called mitophagy. Autophagy dysfunction in various disease states can inactivate mitophagy and cause cell death, and defects in mitophagy are becoming increasingly recognized in a wide range of diseases from liver injuries to neurodegenerative diseases. Here we highlight our current knowledge on the mechanisms of mitophagy, and discuss how alterations in mitophagy contribute to disease pathogenesis. We also discuss mitochondrial dynamics and potential interactions between mitochondrial fusion, fission and mitophagy.

According to the development of information technology (IT) and new media, customers’ needs have changed to seek not only high quality goods but also a differentiated service in retail stores (Lee & Shin, 2011). For this reason, fashion retail stores started to provide an interesting service by setting up an IT machine or a gadget in the stores. Thereby, customers can get the information or have a special experience while they shop fashion goods. IT shopping service is defined as using technology in retail stores to enhance interaction between retailers and customers. Retailers have tried several types of IT shopping services, which offer information or experience with a high or low level of technology. Informative IT shopping service provides various and useful information, which is related to each product such as size, color, contents, stock, location and fashion styling. Retailers use experiential IT shopping service as an emotional appeal that gives direct experience to customers in some way or other such as watching or acting in a virtual situation. Also, as technology develops, IT shopping services are embodied with diverse technology that are simple or complexity. Some are easy to use with one button and shows 2D images only, but some have a lot of contents such as video clips, SNS share service, showing 3D images, and implementing augment reality. We saw customer responses on the attributes of IT shopping service (informative vs. experimental) x technology level of IT shopping service (high vs. low) x fashion innovativeness/technology innovativeness (high vs. low) This study aims to see the effect of the attributes of IT shopping service and the level of technology on procedure satisfaction and outcome satisfaction, and the moderating effect of perceived enjoyment and perceived complexity. Furthermore, this study will see whether these effects affect visit intention. In this study, the experimental design was adopted as the main methodology, and a total of four stimuli types were selected: 1) informative x high technology 2) informative x low technology 3) experiential x high technology 4) experiential x low technology. The common element, which all types of stimuli have, is a digital touch screen since it is a general equipment nowadays, and the common fashion good for all types is a black blazer. The type of informative service only has the information (size range, color assortment, contents, stock) about selected fashion good with its image. High technology in informative service shows the image with 3D simulation that can help to see 360° of the blazer, and styling tips including a video clip. Moreover, it helps to share the information with friends via SNS. Low technology in informative service only shows a front side of the blazer and presents a store map for customers to find a product they want to try. The types of experiential service draw customer participation providing a picture of customers that are trying on clothes. Experiential service use augment reality (AR) as a high technology and take the back side of customers picture as low technology. For the manipulation check, 18 graduate students in total viewed for each type, and the total sample comprises 387 college students via survey instrument. All hypotheses were tested using AMOS and SPSS 18.0. The main findings of this study are as follows: depending on type of the attributes of IT shopping service and the level of technology affect perceived enjoyment and perceived complexity differently, and there were significant mediating effect of perceived variables toward IT shopping service on procedure satisfaction, outcome satisfaction, and visit intention. Implications for usefulness and role of the IT shopping service in fashion retail stores are provided. And also, limitation of this study and future study are suggested.

Sooyeon Lee,Jiyoung Yoon 한국조리학회 2024 한국조리학회지 Vol.30 No.2
The purpose of this study is to enhance the quality of franchised restaurant service by reducing potential service failure based on the risk priority of service failure. Failure mode and effect analysis (FMEA) was adopted to either address service failure or to improve the overall service quality in franchised restaurants. In addition, the study bolsters the analysis with fuzzy inference, a solid mathematical inference system when it comes to utilizing experts evaluation, thus reducing the linguistic ambiguity inherent in experts risk assessment and eliciting the objective risk value of each service failure mode. 70 respondents who have at least two years work experience as a manager in a franchised restaurant were only eligible to participate in the research. Fuzzy Logic Toolbox on MATLAB was used for fuzzy inference and determination of the risk priority. The results provided the risk priority of each service failure mode. The highest risk of service failure modes were ‘foreign substance contaminants in served food (7.40)’, ‘unfriendly employees (7.32)’, and ‘unclean tableware (7.17)’, with fuzzy value of more than 7. In contrast, ‘restaurant interior that does not match brand image (3.47)’, ‘lack of variety in the menu (3.72)’, ‘absence of background music (3.93)’, ‘absence of wait guidance (3.97)’ were classified as the lowest risk among the failure modes. The study expects several theoretical and practical contributions by applying the mathematical cognitive model in service failure analysis and suggesting a solution to prevent service failures.
