Objectives: A salmonellosis outbreak occurred within a community of Gyeongju residents who ingested catered food from a wedding in June 2009. We aimed to epidemiologically investigate the probable vehicle of the infection. Methods: We conducted a retrospective cohort study on 34 local residents who ingested the wedding food. Results: Among the 34 residents, 31 (91.2%) reported symptoms of infection after eating the food. Among all of the wedding foods, pan-fried foods were highly associated with the diarrheal attack rate. On bacteriological examination, Salmonella species were detected in the pan-fried foods among the leftover foods and in 17 of the 31 stool specimens from the cases. There were five different types of pan-fried foods, but the onset of symptoms was independent of the ingredients used. We found that the pan-fried food was prepared at a food store in Seoul and that eggs were a common ingredient. Conclusions: The major cause of the salmonellosis in this population was presumed to be the pan-fried food prepared with contaminated eggs. These food items might have been partially undercooked because of their irregular shape, which allowed the Salmonella species to survive and multiply before ingestion.

Purpose: The purpose of this study is to analyze health status of women working in traditional marketplace and their needs for public healthcare services. Methods: A descriptive survey of 500 women working at three traditional marketplaces was conducted. Results: street vendors' health status were much poorer than store merchants'. Furthermore, psychosocial factors like job stress and depression were increased in street venders. Thus, the public healthcare programs required by them included exercise programs (28.2%) and health checkup (26.8%). In addition, 31.2% of the participants reported that they needed visiting nursing care services. The rate of occupational health and safety or employment insurances was as low as 10.8%. Conclusion: Effective interventions including psychosocial factors for women workers at traditional marketplaces need to be developed based on these results. Also, it is recommended that public health care services such as outreach services and visiting nursing care services for women working at traditional marketplaces be provided. Furthermore, institutional provisions such as insurances for protecting these vulnerable groups' health are needed.

Purpose - This paper aims to examine several time series models to predict sales of department stores and discount store markets in South Korea, while other previous trial has performed sales of convenience stores and supermarkets. In addition, optimal predicted values on the underlying model can be got and be applied to distribution industry. Research design, data, and methodology - Two retailing types, under investigation, are homogeneous and comparable in size based on 86 realizations sampled from January 2010 to February in 2017. To accomplish the purpose of this research, both ARIMA model and exponential smoothing methods are, simultaneously, utilized. Furthermore, model-fit measures may be exploited as important tools of the optimal model-building. Results - By applying Holt-Winters' additive seasonality method to sales of two large-scale retailing types, persisting increasing trend and fluctuation around the constant level with seasonal pattern, respectively, will be predicted from May in 2017 to February in 2018. Conclusions - Considering 2017-2018 forecasts for sales of two large-scale retailing types, it is important to predict future sales magnitude and to produce the useful information for reforming financial conditions and related policies, so that the impacts of any marketing or management scheme can be compared against the do-nothing scenario.

This paper aimed to investigate the influence of consumer lifestyle on consumer selection of bakery cafe attributes. Data were collected through a self-administered questionnaire by 403 random consumers between the ages 20s and 30s in several bakery cafes in Seoul and Gyonggi area. Different methods of statistical analysis had been used such as frequency analysis, factor analysis, k-means clustering analysis, cross tabulation, one way ANOVA and Duncan's multiple range test with SPSS for Window 13.0 package. First, when analyzing the 16 questions of comsumer lifestyles, four factors were extracted: 'dining out-oriented factor', 'achievement-oriented factor', 'brand-oriented factor', and 'health-oriented factor'. Second, the respondents were divided into three groups by k-means cluster analysis: no interest group, dining-out & value oriented group, and health-brand oriented group. Third, consumer's bakery cafe attributes were categorized into five factors including 'food', 'convenience and image', 'store promotion', 'positive dining experience', and 'menu & merchandises'. Finally when analyzing the differences in the selection of bakery cafe attributes according to consumer's lifestyles, it showed a significant differences.

Data were collected through focus group interviews. Eleven females in their 20s and 30s, who have extensive experience in reading consumer reviews posted on online apparel stores, participated in the study. The consumer review information considered important by participants is the information related to seven product attributes (size, fabric, design, color, sewing, price, and country of origin), seven benefits (functional, financial, esthetic, emotional, social, utilitarian benefits, and product value compared to price) of the apparel product and four store attributes (return/refund, delivery, reputation/credibility, and customer service). The findings from the study can serve as an important tool in developing survey questions in order to evaluate the quality of consumer review information and help online retailers plan methods to improve the quality of reviews.

The Purpose of this research was to propose positioning strategies of urban park (UP) based on the assessment of location characteristics at cheongju city. To do that, this research found out urban park service area (UPSA) using GIS network analysis and built socio-economic attribute database, UP map, and other public service thematic maps such as public transportation, education, child-care, and convenience services. And this research analyzed spatial and attribute data using Pearson's correlation analysis, multiple linear regression, and binary logistic regression methods. As a result of this analysis, 1) the nearer neighborhood park and children's park, the higher land price and assumption income level (AIL). 2) children's parks were closed to living convenience facilities such as bank, hospital, and convenience store. 3) land price, AIL, population, and other public services level (PSL) in UPSA were higher than that of non-UPSA. 4) The higher land price, AIL, population, and other PSL, the higher urban park service level.

냉동 저장온도에서 비동결 상태로 액란을 저장할 수 있는 방법을 연구하기 위하여 cryoprotectants를 첨가하거나 papain으로 처리하여 $-15^{\circ}C$에서 저장하면서 품질변화를 조사한 결과는 다음과 같다. Cryoprotectants로는 제품의 향미를 고려하여 fructose와 glucose를 45 : 55로 혼합하여 사용하는 것이 좋고, whole egg나 난황을 $-15^{\circ}C$에서 비동결 상태로 저장하는데 필요한 cryoprotectants의 농도는 각각 70.3%와 45.2%이었다. 그리고 액란에 cryoprotectants를 첨가하여 저장하면 gel화를 효과적으로 방지할수 있었으며, gel화가 발생한 액란에서는 consistency의 증가, 단백질 침전도의 증가 및 미세구조의 파괴를 볼수 있었다. 액란에 0.15%.papain을 처리한 후 냉동온도에서 저장하면 액란의 gel화를 상당히 방지할 수 있었다.

네트워크 기반 단말 정보 식별 도구는 일반적으로 포트 스캔을 사용해 네트워크 단말들의 정보를 탈취하고 취약점을 찾아낸다. 특히 Shodan과 Censys는 네트워크 기반 단말 정보 식별 도구를 이용하여 광범위한 단말 정보를 탈취하여 데이터베이스에 저장한 후, 이를 사용자에게 제공한다. 이 정보는 누구나 확인할 수 있기 때문에 사이버 공격에 악용될 수 있다. 따라서 네트워크 단말 정보 탈취 방지가 필요하며, 이를 위해서는 스캔 도구가 사용하는 스캐닝 방법을 알아야한다. 하지만 Shodan과 Censys가 사용하는 스캐닝 방법은 잘 알려져 있지 않다. 따라서 본 논문에서는 Shodan과 Censys의 스캐닝 방법을 추정해 모델링하고 성능을 분석하였다.
