  • Recently in the Mongolian wireless marketplace, many E-commerce companies have been making considerable investments in the technological development of M-commerce, taking competitive advantage of new business possibilities offered by Internet-based wireless technologies. In the Mongolian wireless marketplace, this new mobile environment opens the door for new and exciting market opportunities in mobile services and applications. In the near future, these companies will be looking toward M-commerce services as a supplemental source of revenue in the mobile marketplace. This paper examines the roles of M-commerce in the consumers' in order to promote the consumers' loyalty in the booming M-commerce. This paper contains theory that focuses on the basic concepts of the M-commerce environment, its wireless network technologies, and its applications infrastructure. Upon searching for references to assist us in establishing a market hypothesis, we discovered that few comprehensive studies on consumer perspective and behavior related to M-commerce services actually exist in the literature. In the area of M-commerce, many companies neglect the consumer perspective, concentrating only on technological factors only when formulating their market strategies. And, due to technological blindness, many companies were not able to succeed in end-user E-commerce services. Given that fact, this paper formulates a consumer-centric research model. In order to prove the research model, we chose the survey method which allows for the collection of large amounts of data from a sizeable population in a highly economical way. Through the survey, this paper defines consumer's attitudes towards M-commerce services by identifying potential Business-to-Commerce(B2C) applications and its primary target groups in terms of gender and age, and by investigating whether consumers recognize the value proposition of M-commerce applications and services. As shown in the data analysis and results, this research concludes that M-commerce development in Mongolia is still at its infancy, and that the implementation of M-commerce depends not only on technological progress, but also on consumer attitudes and their willingness to adopt M-commerce services. As well, other complex cross-cultural factors-socially, economically, culturally, et cetera-enter strongly into the equation.

  • The purpose of this study was to assess the prospective teachers' perception of food risk with the goal of providing the ways to improve their knowledge and perception of food risk. A self-administered questionnaire was developed and offered to 307 freshman and sophomore in an elementary teacher-cultivating university located in Seoul. The collected data were analyzed in terms of frequencies, cross tabulation analysis, t-test and ANONA with a deviation level of 5% using SPSS 15.0. The results of this research were as follows: 'Taste' was identified as an important factor for purchasing food (54.4%), and 'Manufacture date/expiration date' (67.0%) was checked first before food was purchased. The respondants viewed food additives (66.8%) followed by environmental contaminants (17.6%) as the most dangerous factors for food consumption. Even though they did not know the actual level of risk these factors posed to food, they still perceived them as dangerous. Most of them did not have any educational experiences on food risk, and if any, their sources of information were TV (46.6%) and the internet (19.5%). And, they did want to have information on food risk through TV, radio (41.1%) and the internet(16.4%). Based on the above results, the subjects who have great potential to influence children appeared not to have sound knowledge or a balanced perception of food risks. Therefore, systematic educational opportunities for prospective teachers should be provided to promote food risk communication.

  • 태양면의 교란으로 야기되는 지구근방 우주환경의 변화는 인류에게 막대한 사회경제적인 손실을 유발하므로 이를 예측하는 것은 매우 중요한 일이다. 본 연구에서 도입한 자기폭풍 예보코드는 이러한 변화양상을 지자기활동지수인 AE 및 Dst, 극관횡단전위차, 극지방전리층에서 소모되는 에너지 그리고 여기에 수반되는 열권의 온도상승 등의 형태로 예보하도록 고안되었다. 본 예보코드는 플레어 관측으로부터 태양풍 그리고 행성간자기장을 예측하는 부분과 추정된 태양풍파라미터로 표현되는 태양풍-자기권상호작용함수인 $\varepsilon$으로부터 상기 물리량들은 추정하는 부분으로 나누어져 있다. 1993년 11월 초에 발생한 자기폭풍에 이 예보코드를 적용하여 그 결과를 일본인공위성인 Geotail에 의한 태양풍관측결과와 지자기관측소에서 얻은 지자기 활동지수들과 비교하였다. 비록 많은 부분에서 아직 개선되어야할 여지가 발견되었지만 태양 플레어로 야기되는 지구근방 우주환경에 교란상태를 예측하는데 근사적이지만 본 예보모델이 사용될 수 있음을 확인하였다.

  • The conceptual site model (CSM) is used as a key tool to support decision making in risk based management of contaminated sites. In this work, CSM was applied in Jeonju Industrial Complex where site investigation for groundwater contamination was conducted. Site background information including facility types, physical conditions, contaminants spill history, receptor exposure, and ecological information were collected and cross-checked with tabulated checklist necessary for CSM application. The CSM for contaminants migration utilized DNAPL transport model and narrative CSMs were constructed for source to receptor pathway, ecological exposure route, and contaminants fate and transport in the form of a diagram or flowchart. The component and uncertainty of preliminary CSM were reviewed using the data gap analysis while taking into account the purpose of the survey and the site management stage at the time of the survey. Through this approach, the potential utility of CSM was demonstrated in the site management process, such as assessing site conditions and planning follow-up survey work.

  • Broadband Internet has proven to be vital for economic growth in developed countries. Developing countries have implemented several initiatives to increase their broadband access. However, its full potential can only be realized through adoption and use. With lower-middle-income countries accounting for the majority of the world's unconnected population, this study employs the theory of planned behavior (TPB) to investigate users' intentions to adopt broadband. Rural Tanzania was chosen as a case study. A cross-sectional study was conducted over three weeks, using 155 people from seven villages with the lowest broadband adoption rates. Non-probability voluntary response sampling was used to recruit the participants. Using the TPB constructs: attitude toward behavior (ATB), subjective norms (SN), and perceived behavioral control (PBC), ordinal regression analysis was employed to predict intention. Descriptive statistical analysis yielded mean scores (standard deviation) as 3.59 (0.46) for ATB, 3.34 (0.40) for SN, 3.75 (0.29) for PBC, and 4.12 (0.66) for intention. The model adequately described the data based on a comparison of the model with predictors and the null model, which revealed a substantial improvement in fit (p<0.05). Moreover, the predictors accounted for 50.3% of the variation in the intention to use broadband Internet, demonstrating the predictive power of the TPB constructs. Furthermore, the TPB constructs were all significant positive predictors of intention: ATB (β=1.938, p<0.05), SN (β=2.144, p<0.05), and PBC (β=1.437, p=0.013). The findings of this study provide insight into how behavioral factors influence the likelihood of individuals adopting broadband Internet and could guide interventions through policies meant to promote broadband adoption.

  • Background: Since cervical cancer can be prevented and controlled through human papillomavirus (HPV) vaccination, it is important to train health care providers and provide them with appropriate knowledge. This study aimed to understand the level of HPV related knowledge among medical students and correlates in Southwest China in order to address any potential gap in their knowledge base. Methods: We conducted a cross-sectional survey among medical students in six selected universities across Southwest China based on a pretested questionnaire regarding HPV infection, cervical cancer, and HPV vaccines. Results: We successfully surveyed 1, 878 medical students, of whom 32.1% were males and 67.9% were females. Their mean age was 20.8 (standard deviation: 1.3) years. 91.8% of them were ethnic Han Chinese, and 43.8% were students in clinical medicine. While 76.5% had heard of HPV only 48.8% knew that the prevention of cervical cancer was possible through HPV vaccination. Only 42.9% of the male and 49.2% of the female students correctly answered over 10 out of 22 questions on HPV related knowledge. Female students appeared to know more about HPV and HPV vaccination (OR: 1.39; 95% CI: 1.11-1.75). In addition, the student knowledge improved with the grade (p<0.001). University courses were the most selected source of knowledge about HPV vaccination (66.4%). 83.6% of males and 91.4% of females were willing to have more HPV related education by experts (p<0.001). Only 10.1% of the students acknowledged that people had asked for their advice regarding HPV vaccination. Conclusions: Our survey indicates that medical students from Southwest China have poor knowledge of HPV and HPV vaccination, but are willing to receive more relevant information. Targeted education should be incorporated into school courses to inform these future health care providers and ensure success of programs for cervical cancer control and prevention.

  • 본 연구의 목적은 연쇄방화범과 단순방화범의 사회경제적 특징, 범죄현장에서의 행위적 특징 등에서 어떤 차이점이 발견되는지를 살펴보고 이를 토대로 공경비와 민간경비 차원에서의 방화예방책을 논의하는 데 있다. 연구에 사용된 데이터는 경찰청에서 운영 중인 과학적 범죄분석시스템(SCAS) 자료를 기본으로 하였으며, 수사종합검색시스템(CRIFISS), 범죄정보관리시스템(CIMS) 자료를 보충적으로 활용하였다. 구체적으로 2000년 초부터 국립과학 수사연구소 범죄분석실과 경찰청 범죄행동분석팀에서 합동으로 실시한 전국의 주요 방화사건 중 기소 전 경찰 수사단계에서의 피의자에 대한 면접자료 160건을 연구분석 자료로 사용하였다. 연쇄방화범과 단순방화범의 행위적 특성에 대한 교차분석결과 다른 독립변인들에 비해 가장 뚜렷한 차이점이 발견되었다. 즉 연쇄방화범은 피해장소나 피해대상을 노상이나 무작위 장소의 쓰레기나 적치물을 이용하여 방화하는 경향이 높으며, 그런 장소에서 쉽게 구할 수 있는 종이류를 사용하며, 사전에 방화도구를 준비하지 않고, 현장에서 바로 입수 할 수 있는 것들을 사용하는 경향이 있었다. 또한 범죄 후 사법기관에 검거될 수 있다는 두려움이 단순방화범에 비해 훨씬 약하기 때문에 방화 후 현장을 조작하지 않을 가능성 높고, 도보로 현장을 빠져 나오는 경향이 높았다. 또한 방화의 원인이 흥분이나 현실불만일 가능성이 높기 때문에 방화 피해자와 비면식일 가능성이 높고, 흥분이나 현실불만을 고취시키기 위해 음주상태에서 방화사건을 저지를 가능성이 높은 것으로 나타났다. 이 연구는 방화범에 대한 문헌연구가 아닌 경찰청이 보유한 실증적, 경험적 자료를 사용했기 때문에 향후 방화범죄에 대한 연구와 공경비와 민간경비 강화의 모델 구축에 중요한 토대가 될 수 있는 의미 있는 연구결과를 발견했다는 점에서 연구의 중요성이 부각될 수 있을 것이다.

  • The current study was conducted to investigate the relationship between stress related gene and meat quality in pigs. A total number of 212 three-way cross bred (Landrace-$Yorkshire{\times}Duroc$) and 38 Duroc were sampled from the Korean pig industry to determine genotype frequency of porcine stress syndrome (PSS) and heat shock protein 70 kDa (HSP70) genes and their relationship with carcass traits and longissimus meat quality. Screen of HSP70 was performed by the single strand conformation polymorphism (SSCP) technique. Based on the analysis of restriction fragment length polymorphism (RFLP) in ryanodine receptor 1 (RYR1) gene, genetic disorder of PSS was related to a mutation at $18,168^{th}$ (C to T) of exon 17. There was no significant difference in ultimate meat pH and backfat thickness between HSP70 K1-AA type and -BB type in pure Duroc breed. In Landrace-$Yorkshire{\times}Duroc$ (L-$Y{\times}D$) cross bred pig, our results indicated that HSP70 derivate type in Duroc had a limited effect on backfat thickness, but L-$Y{\times}D$ type had a noticeable linkage with HSP70 K1-AA and K3-AB. This tendency was also observed in hot carcass weight where HSP70 K1-AA and K3-AB resulted in heavier weight with 86.3 kg compared to HSP70 K1-AB and K3-BB of 74.3 kg. Results imply that stress related HSP70 genotype has a potential association with backfat thickness and carcass weight.

  • 목적: ACOVE project에서는 말기 치료의 질 평가를 위한 임상질지표를 개발하였다. 그러나 말기 치료에 대하여 의료전문가들의 의견을 반영하여 만든 임상질지표와 보호자들의 의견은 실제로 다를 수 있다. 따라서 호스피스 치료 질에 대한 보호자들의 인식 정도를 파악하기 위해 본 연구를 시행하였다. 방법: 2009년 7월부터 10월까지 총 4개월간 경북대학교 병원과 대구 보훈병원의 호스피스 병동에 입원해 있는 환자의 보호자를 대상으로 익명의 횡단면 질문지 조사(cross-sectional anonymous questionnaire)를 시행하였다. 총 120명을 선정하고 이 중 모든 질문에 성실히 답한 69명을 최종대상자로 하였다. 통계분석은 SPSS WIN ver. 14.0을 이용하여 independent t-test와 Pearson's chi-square test를 시행하였다. 결과: 좋은 임상질지표 중 가장 동의율이 높은 항목은 '완화의학 팀이나 완화의학 전문가에 의한 의학적 진찰'과 '가족들이 지켜보는 앞에서의 임종' 이었으며 이 항목들은 88.4%의 보호자가 동의하였다. 반면에 낮은 동의율을 보인 항목은 '환자와 심폐소생술에 대해 논하는 것' 으로 15.9%가 동의하였다. 나쁜 임상질지표 중 동의율이 높은 항목은 '낙상이나 욕창이 발생하는 것은 바람직하지 않다' 라는 항목이었으며 94.2%의 보호자가 동의하였고 가장 낮은 동의율을 보인 것으로는 '병원에서 임종하시는 것은 바람직하지 않다'라는 항목으로 11.6%가 동의하였다. 그리고 동의를 많이 한 그룹일수록 여자의 비율, 환자가 자신의 예후를 인지한 비율, 경제 수준이 높은 사람의 비율이 높았다. 결론: 본 연구에서는 이전 여러 연구에서 임상질지표로 권유되어진 항목들에 대한 보호자들의 동의율이 낮은 항목들이 있었으며 일부 항목들의 동의율과 보호자들의 특성이 관련이 있었다.
