Generalized anaphylaxis is a most dramatic and acutely life-threatening allergic reaction. Most fatalities from anaphylaxis occur within the first 30 minutes postantigenic exposure. The mechanism of generalized anaphylaxis is the reaction of IgE antibodies to an allergen that causes the release of histamine, bradykinin, and others. These chemical mediators cause the contraction of smooth muscles of the respiratory and intestinal tracts, as well as increased vascular permeability. Four major clinical symptoms are recognized: skin reactions, smooth muscle spasm (gastrointestinal and genitourinary tracts and respiratory smooth muscle), respiratory distress, and cardiovascular collapse. Epinephrine is the drug of choice for the management. Its syrnpathomimetic effects directly counteract most aspects of the attack. Respiration must be immediately supported by the establishment of a patent airway along with artificial ventilation. The circulation should be supported and the existing hypotension overcome by placing the victim in a position to allow gravity to aid venous return and by administering intravenous fluids, vasopressors, and corticosteroids. When an imperceptible pulse is evident, external cardiac compression must also be instituted. This is a case report of anaphylactic shock care during general anesthesia, possibly due to penicillin, pancuronium and others.

Purpose: The purpose of this study was to integrate and synthesize findings from qualitative studies exploring male students' experiences of adapting to nursing education programs so as to obtain further understanding of the phenomenon. Methods: The meta-synthesis process was primarily guided by Noblit and Hare's approach, which consists of four stages including searching, appraisal of an individual study's quality, data extraction for analysis, and meta-synthesizing the results. Results: Findings from the literature reviewed were synthesized into six themes: 1) extraordinary choice based on job stability and gender scarcity; 2) unexpected feeling of marginalization as minority far apart from the mainstream; 3) assimilation and negotiation for relational adaptation through perspective shift; 4) fortifying the vision and identity as nursing students by meaning making for adapting to the nursing major; 5) mutual support among colleague male students; and 6) serving in the military as way of hiding out and achieving maturation. Conclusion: The findings illustrate that nursing education programs need practical changes promoting male students' adaptation to the program itself as well as preparation to be a professional nurse in the future.

An efficient method of extraction for carotenoids in Rhodotorula glutinis KCTC 7989 was developed. Major carotenoids produced were identified as torularhodin of 61.7%, $\beta$-carotene of 28.8%, and torulene of 9.5%. HCI treatment, as a pretreatment on cell, was necessary to carry out together with thermal treatment unlike DMSO pretreatment. The choice of solvent had an important effect on the composition of carotenoids extracted: benzene and chloroform were effective for the extraction of torularhodin, especially. However, diethyl ether was most effective for the extraction of total carotenoids. Freeze dried type cells showed high efficiency value for the extraction of carotenoids, in compared with dried and wet type cells.

This study was conducted to investigate the eating out behavior and its factors in restaurant selection by students in Incheon area. Self administered questionnaires were collected from 297 students. Statistical data analysis was completed using a SPSS v. 10.0 program. The results are summarized as follows: The average age, weight, height, BMI and male and female students were $24.31,\;67.96\cal{kg},\;174.93\cal{cm},\;22.17\;;\;20.55,\;51.99\cal{kg},\;165.44\cal{cm},\;19.00$ reflectively. About $54.2\%$ of male students and $38.0\%$ of female students responded to eat out at least once a day. And lunch was most frequent meal for eating out. About $57\%$ of students responded to have eat at restaurants around campus, and $19.5\%$ of students used the university foodservice system. Korean-style food was most favorite dish when they ate out. Major source of restaurants information was recommended action by friends or family. But the use of internet or magazine was negligible. The factor of restaurants choice was in order 'taste', 'price', 'atmosphere' and 'hygienic'.

The purpose of this study was to examine the actual state of cooking wine usage, and analyze the relationship between the attributes of cooking wine and demographic characteristics. The major findings of this study are as follows. First, the origin and correct choice of cooking wine were significantly related to hotel type, restaurant type and career. Second, the importance of the taste and aroma of a cooking wine, which are intrinsic attributes in the evaluation of a wine, had significant relationships with all the demographic variables whereas the importance of purchase cost and label information of the cooking wine only exhibited a significant correlation with career (p<0.05). Third, 53.7% of the respondents used cooking wine based on recipes, while the rest used it by rule of thumb. These results between restaurant type were significantly different (p<0.05). For the results of this research to be of more use, further research should be conducted on the functional aspects of cooking wine and their effects on cooking. In addition, further systematic research should be performed on the functional and sensory effects of a variety of wine tastes and aromas on cooking.

The purpose of this study was to investigate the preference on Korean food and the nutritional knowledge of the college students. Self-administrated questionnaires were completed by 556 college students majoring food-related subjects in Kangwon-do area. The results were as fellows : 1. Male subjects liked meat (Calbi, Bulgogi, Seolungtang) and female subjects liked Kimchi and soybean soup. Both genders, however, disliked seasoned vegetables. 2. In the frequency of taking, Kimchi had the highest rank followed by Bibimbab and Seolungtang in higher order. 3. The first choice of both family and friends eating out was Korean foods. 4. The top two reasons for selecting Korean foods were their deliciousness and availability in higher order. 5. According to this study, the establishment of standardized recipe and the different way of facing Korean foods of individuals (Koreans) are promptly required for the globalization of Korean foods. 6. The nutritional knowledge of the subjects were limited and restricted to simple facts regardless of their major.

The aim of this study is to find the key elements for the successful introduction of a Cyber University (CU) in Korea. Since information technology (IT) has dramatically changed our lives it is inevitable for education to follow suit. The old education system was based on the following principle, of a teacher physically interacting with his or her pupils at a school. However, this is set to become infinitely more flexible with the freedom of choice given to the pupil who are now able to adopt, beyond barriers of time and space what, and how they study. All this will be made possible with the use of IT. The essentials for the CU would be a positive and flexible education paradigm, also able to satisfy students with a totally new system of education that replaces physical interaction with virtual interaction. Another point that needs to be taken into account is the number of potential students, their expectations and needs. And any national or international restrictions need to be addressed. One major hurdle for the acceptance of a CU in Korea is the vast difference between its conservative culture and directness of Western culture. Despite this, it will soon become imperative for Korea that she embraces the rapidly changing attitudes and requirements in order for the survival of the nation and an individual.

In the more than 100 genome wide association studies (GWAS) conducted in the past 5 years, more than 250 genetic loci contributing to more than 40 common diseases and traits have been identified. Whilst many genes have been linked to a trait, both their individual and combined effects are small and unable to explain earlier estimates of heritability. Given the rapid changes in disease incidence that cannot be accounted for by changes in diagnostic practises, there is need to have well characterized exposure information in addition to genomic data for the study of gene-environment interactions. The case-control and cohort study designs are most suited for studying associations between risk factors and occurrence of an outcome. However, the case control study design is subject to several biases and hence the preferred choice of the prospective cohort study design in investigating geneenvironment interactions. A major limitation of utilising the prospective cohort study design is the long duration of follow-up of participants to accumulate adequate outcome data. The GWAS paradigm is a timely reminder for traditional epidemiologists who often perform one- or few-at-a-time hypothesis-testing studies with the main hallmarks of GWAS being the agnostic approach and the massive dataset derived through large-scale international collaborations.

When cells are stimulated by growth factors, they make a critical choice in early G₁ phase: proceed forward to S phase, remain in G₁, or revert to G₀ phase. Once the critical decision is made, cells execute a fixed program independently of extracellular signals. The specific stage at which the critical decision is made is called the restriction point or R-point. The existence of the R-point raises a major question: what is the nature of the molecular machinery that decides whether or not a cell in G₁ will continue to advance through the cell cycle or exit from the cell cycle? The R-point program is perturbed in nearly all cancer cells. Therefore, exploring the nature of the R-point decision-making machinery will provide insight into how cells consult extracellular signals and intracellular status to make an appropriate R-point decision, as well into the development of cancers. Recent studies have shown that expression of a number of immediate early genes is associated with the R-point decision, and that the decision-making program constitutes an oncogene surveillance mechanism. In this review, we briefly summarize recent findings regarding the mechanisms underlying the context-dependent R-point decision.

There are flourishing studies in the acceptance or usage of information systems literature. Most of them have taken the pro - acceptance view. Undesirably, information technologies often provoke users' reactance or resistance. This paper explores one of the negative reactions -psychological reactance. The present paper studies the effects of the users' perception of threatened freedom and personalization degree on intention to use recommendation services. High personalization can be a major motivation for users to accept recommendation systems. However recommendation services are a two-edged sword, which not only provides users the efficiency of decision making but also poses threats to free choice. When people consider that their freedom is reduced or threatened by others, they experience the motivational state to restore the freedom. This motivational state must be considered in understanding usage of information systems, especially personalized services which are designed for persuasion or compliance. This paper empirically investigates the effect of personalization and the psychological reactance on the intention to use information systems in the personalized recommendation context. Users' perception of personalization increases the usefulness of recommendation service while their perception of threat to freedom reduces the intention to use personalized recommendation service. Findings and implications are discussed.
