컴퓨터와 네트워크의 보급이 일반화되면서 인터넷을 통한 정보 전달이 일상 생활처럼 되고 있다. 또한 인터넷, 무선통신, 그리고 자료교환에 대한 증가로 인해 다른 사용자와 접속하기 위한 방식은 빠르게 변화하고 있다. 그러나 이러한 전자메일에도 많은 문제가 존재한다. 기존의 전자메일은 간단한 방법으로 내용을 열람하거나 변조할 수 있어 중요한 정보나 사생활 노출의 위험에서 벗어날 수 없다. 이러한 데이터에 대한 보안이 기대에 미치지 못하고 있기 때문에 암호학적으로 강력한 전자메일 시스템의 개발이 시급하다. 본 논문에서는 기본적인 정보보호 서비스 외에 기존의 전자메일 시스템에서는 제공되지 않는 배달 증명 및 내용 증명 기능을 제공하고 자바 암호 API를 사용하여 안전한 키 교환이 가능하도록 하였다.

Purpose: The present study aims to identify research trends on diabetes mellitus (DM) self-management intervention, suggesting directions for follow-up studies through a scoping review. Methods: This study conducted the scoping review process outlined by Arskey and O' Malley using the JBI (Joanna Briggs Institute) template. The databases used were Riss, Kiss, NDSL, KMbase, Google Scholar. This study searched the literature published between January 2011 and November 2021 by entering keywords related to DM self-management. Results: Thirty-five studies were selected for analysis. The period for 24 articles was 12 weeks or longer. The interventions consisted of education, exercise, counseling, and coaching. Not all studies applied the theory of behavior change. Fourteen studies included three factors relating to behavioral, cognitive, emotional, and blood sugar changes to measure effectiveness, while ten studies included all four factors. Most interventions were effective both in DM self-management and self-care. Further, the intervention persistence effect of each study varied. Conclusion: While research on DM self-management intervention has been conducted at domestically and abroad, this decreased during COVID-19 pandemic. This study suggests the importance of systematically developing effective necessary optimal DM self-management interventions that can change behaviors to prevent diabetic complications and improve quality of life.

Purpose - With the improvement of people's living standards, traveling abroad has become a common way for people to release the pressure of life and work. In economics, this kind of way can affect the international trade. Because of this background, this paper sets BRICS countries as an example to explore the impact of cross-border tourism on bilateral trade. Research design, data, and Methodology - The annual time series data sets form 1998 to 2016 are used to perform an empirical analysis under a series of econometric approaches such as the Phillips-Perron test and the Engle-Granger two-step test. In this paper, the cross-border tourism and the bilateral trade will be used to conduct an empirical analysis based on the econometric approaches to analyze the impact of cross-border tourism on bilateral trade. Results - The finding of this paper show that there is a long-run relationship between cross-border tourism and bilateral trade in this sample. Moreover, the cross-border tourism is the Granger causality of bilateral trade. Namely, the cross-border tourism can promote the development of bilateral trade. Conclusions - In short, the evidences that this paper presents show that the cross-border tourism is a driving factor that impacts the bilateral trade in the sample of BRICS countries.

The purpose of this study is to understand the characteristics and improvements of Korean foods by using the ISA (Importance Satisfaction Analysis) targeting Korean students in international schools in the Seoul Metropolitan area. It also analyzes the difference in the importance and satisfaction of Korean foods, and to provide basic data for developing various healthy diets which are suitable for target students. Target groups are 7 to 12 graders which consist of 62 male students and 42 female students, and most of them had lived in the United States with duration of staying abroad from 1 year to less than 3 years and duration of attending schools from 1 year to less than 2 years. Most of their family structures are the nuclear family, and most of their fathers work in management positions and mothers are mostly full-time housewives. The most favored and consumed food is fruits and the least favored is seaweeds. Perceptions regarding Korean foods are mainly positive and more female students than male students consider Korean foods as well-being foods. The important factor for choosing Korean food is the flavor, and the highest satisfaction lies in the cleanliness of food and tableware, and food temperatures appear to be less important than other factors regarding both importance and satisfaction aspects. The flavor turns out to be the most influential when consuming Korean foods, and information on Korean foods is mostly acquired from advices of those around and through words-of-mouth, and many comments point out that the levels of sanitation should be improved. The result of ISA regarding determinant factors in choosing Korean foods by Korean students in international schools shows that efforts for aggressive improvements should be made in areas for 'the amount of food', 'the price of food', and 'the curiosity on food'.

Introduction. Cardiovascular disease has the potential to lead to sudden in-flight incapacitation and permanent grounding. The aims of this study are to examine the relationships between lifestyle, job stress and blood lipid levels of male aircrew personnel of a Korean airline and to identify which factors influence their hyper-lipidemia. Methods. Two hundred sixteen male aircrew personnel completed a questionnaire by self-report and consented to participate in the study. The questionnaire collected data related to job stress, life style, serum cholesterol levels and general characteristics of the aircrew. The cholesterol levels of the subjects were collected from their most recent health check-up records. Subjects were divided into two groups (the desirable group and the risk group) based on their serum cholesterol level, 200 mg/dl. Results. Mean age and marital status were significantly different between the two groups. More subjects in the risk group had habits of eating high lipid foods, while more subjects in the desirable group exercised more frequently than the risk group. In logistic regression analysis, after controlling age and marital status, types of working situation (domestic duty or international duty, odds ratio=.390, p=.018), diet (odds ratio=.429, p=.037), and exercise (odds ratio=.320, p=.055) were influencing factors on aircrew's serum cholesterol lev-els. Conclusions. The cholesterol level of aircrew personnel is closely related to their lifestyle, such as lipid diet and exercise. The type of work situations, e.g. staying in an airplane for long periods of time or staying abroad, may influence these diet patterns and exercise habits.
