  • Purpose: The purpose of this study was to explore adult diabetics' eating styles and factors which influence them. Method: The study adopted an ethnographic method based on a perspective which views the eating style as a cultural phenomenon. Data was collected through a personal interview, participant observation, and documented materials from Oct.2001 to Sept. 2002. In this study, fifteen adult diabetics, with an average age of 57, participated. Data analysis was done by the Spradley's taxonomic analysis technique. Result: The patients' eating styles were rooted in their viewpoint on illness as well as the meaning of food. Eating styles were classified into 4 types: Pathology-centered, symptom-centered, need-centered, and role-centered. Conclusion: A conventional approach to the treatment and management of diabetes did not consider the patient's inner world which may play an important role in the successful management of the disease. We found that it was critical for health care personnel to understand patients' values, beliefs and their way of life in order to facilitate the most successful self-care diet.

  • The core issue of ethical problem solving in engineering is to understand what exactly happened and to define its nature. Problems often arise mostly in morally complex situations. Traditional philosophical theories usually focus on extreme conflicts of interest and suggest moral theory-centered problem solving methods. However, these methods are not only difficult to specifically apply to real situations, but also are likely to fail to deal with actual moral issues in engineering fields. This study aims to develop more desirable ethical problem solving methods, based on STS (Science and Technology Studies) and engineering ethics combined. First, we have examined the engineering ethics with implications of an STS perspective, then have analyzed traditional ethical problem solving methods in a critical point of view. This study will suggest a new ethical problem solving method named Matrix Guide, based upon those analyses. Specifically, this study classifies four stages of problem definition, analysis, solving, and feedback. Here, we focus on how to combine technological and non-technological factors in each stage, when we are facing morally complex situations in engineering sectors.

  • The epidermal growth factor receptor (EGFR), a member of the ErbB family (EGFR, ErbB2, ErbB3 and ErbB4), plays a crucial role in regulating various cellular responses such as proliferation, differentiation, and survival. As a result, aberrant activation of EGFR, mostly mediated through different classes of genomic alterations occurring within EGFR, is closely associated with the pathogenesis of numerous human cancers including lung adenocarcinoma, glioblastoma, and colorectal cancer. Thus, specific suppression of oncogenic activity of mutant EGFR with its targeted drugs has been routinely used in the clinic as a very effective anti-cancer strategy in treating a subset of tumors driven by such oncogenic EGFR mutants. However, the clinical efficacy of EGFR-targeted therapy does not last long due to several resistance mechanisms that emerge in the patients following the drug treatment. Thus, there is an urgent need for the development of novel therapeutic tactics specifically targeting mutant EGFR with the focus on the unique biological features of various mutant EGFR. Regarding this point, our review specifically emphasizes the recent findings about distinct requirements of receptor dimerization and autophosphorylation, which are critical steps for enzymatic activation of EGFR and signaling cascades, respectively, among wildtype and mutant EGFR and further discuss their clinical significance. In addition, the molecular mechanisms regulating EGFR dimerization and enzymatic activity by a key negative feedback inhibitor Mig6 as well as the clinical use for developing potential novel drugs targeting it are described in this review.

  • Purpose: The purpose of the study was to understand and describe health-related experience of women with physical disabilities, using feminist qualitative approach. Methods: Eight women with physical disabilities participated to the study. Their mean age was 43, ranging from 39 to 67 years old. The data were collected by individual in-depth interviews and all interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed using traditional qualitative content analysis from a feminist perspective. Results: Six major categories emerged from the data. Category 1: "Isolation and alienation from the world.", Category 2: "A distorted self-image of physically disabled body.", Category 3: "Difficulties due to a fixed gender role.", Category 4: "Constant suffering from chronic pain.", Category 5: "Health problems that they have to endure by themselves.", Category 6: "Sublimation through self-reliance." The results of the study show how Korean women with physical disabilities suffer from social stigma, indifferences, and discriminations and struggle to survive in these unfriendly surroundings. Conclusion: The results of the study would help health professionals in designing effective intervention to improve health and to empower women with physical disabilities by providing deep understanding and critical insights of those women.

  • 본 연구는 사이버윤리와 관련된 2002년부터 2012년까지의 국내 연구들을 메타 분석하였다. 가장 연구가 활발한 연구 분야는 교육학분야로 나타났고, 그 외의 분야로는 법학, 신문방송학, 철학, 사회복지학, 사회학, 행정학, 경영학, 심리학 순이었다. 사이버 윤리는 각 전공분야별로 중점적인 연구 영역이 다르게 나타났다. 사이버연구 분석결과 사이버 공간의 특수성을 반영한 윤리이론 개발이 미흡하고, 대부분의 연구들이 기존의 윤리 철학적 범주를 벗어나지 못하는 경향을 보이는 것이 문제점으로 지적된다. 사이버윤리에 대한 연구의 경향이 추상적인 도덕규범 정립에 그치는 것도 문제점으로 볼 수 있다. 또한 새롭게 등장하는 정보인권에 대한 인식 또한 부족하여 실천적 생활윤리에 관한 연구가 미흡하였다. 향후 연구에 있어서 사이버 공간의 정보인권적 윤리의식이 제고되어야 하고, 학제간의 융합적인 연구의 필요성도 요청된다.

  • Outcome-Based education (OBE) is reviewed from the institutional perspective. The demand for and international trends in OBE are briefly examined and several term related to OBE, especially educational objective and program outcomes (POs), are introduced. It is stressed that systems for continuous quality improvement and quality assurance should be established to ensure the maintenance of the OBE system. Because the criteria for accreditation contain a criterion regarding the quality assurance related to program outcomes, several critical issues are considered regarding the POs themselves and the reduction of the POs. The core value of OBE is not only to provide appropriate education services to students to prepare them with the minimum skills and abilities for advancing their professional service, but also to guarantee the quality of graduates. In addition, the educational program should be continuously improved by employing the evaluation results acquired during the operation of the OBE systems. It is certain that an OBE system is one important aspect of student-centered education.

  • Purpose: This paper uses the resource-dependency theory to present the case of the Pakistan sugar industry to highlight how the industry uses a strategic alliance to gain a powerful bargaining position over its critical dependencies. The case of the Pakistan sugar industry is well-known and it is common knowledge that the alliance or the cartel within it is responsible for frequent price hikes and sugar supply shortages in the country. Research design, data and methodology: We use a case study, qualitative document analysis design to trace how the alliance overcomes its various dependencies, and in doing so, how does it harm various stakeholder interests. Results: This paper finds that the sugar industry alliance maintains its bargaining power by manipulating sugar supply through horizontal alliances, political affiliations, underselling and under-reporting sugar stocks, purchasing sugarcane from the black market, and by gaining billions of rupees in export subsidies by hoarding stock and using its political connections. Conclusion: The paper concludes by providing a summary of the measures which the government has taken to curb this anticompetitive conduct; the most important of which is the removal of protectionist measures for sugar trade and allowing market forces to control the demand and supply of sugar in the local market.

  • With the rapid development of the Internet, online shopping has grown so fast that almost any good or service can be sold online today. The popularity and rapid growth of e-commerce signal a huge market opportunity for e-retailers. From the organizational perspective, it is necessary to evaluate and explore what drives customers to buy their products or to use their services. This study, therefore, aims to explain the online purchase intention and its determinants of Vietnamese customers for cosmetics and personal care products. Quantitative data was collected from an online survey conducted among university students, then was put into SPSS and AMOS for further analysis. Descriptive statistics, Cronbach's alpha test, exploratory factor analysis (EFA), regression analysis, and SEM were used to examine data from 434 valid answers. The research findings reveal that four factors positively affect purchase intention: Shopping enjoyment has the most significant impact, followed by trust, benefit, and website quality. On the other hand, perceived risk negatively influences purchase intention. While the cosmetics and personal care industry is thriving with a huge number of producers and consumers throughout the world, this study contributes to the existing literature in terms of capturing customers' needs and developing effective strategies to attract more online users.
