  • This study evaluated the bactericidal effect of 10 sanitizers and disinfectants such as ethanol (75 and 95%), iodine (15 and 25 ppm), chlorine (100 and 200 ppm), quaternary ammonium, acid, hydrogen peroxide, and peroxide acetic acid against V. parahaemolyticus. Ten strains of V. parahaemolyticus isolated from Korean foods and 4 strains of standard V. parahaemolyticus were compared for efficacies of various sanitizers and disinfectants by EN 1276 method based on quantitative suspension test. Ethanol (75 and 95%), 25 ppm of iodine, 100 ppm of quaternary ammonium, 145 ppm of hydrogen peroxide and acid showed more than $5log_{10}CFU/mL$ reduction in both clean and dirty conditions. Tests result of chlorine (100 ppm) showed more than $5log_{10}CFU/mL$ reduction in clean condition. Iodine (15 ppm) showed more than $5log_{10}CFU/mL$ reduction except 4 isolated and 1 standard V. parahaemolyticus in clean condition. iodine (15 ppm) also showed under $5log_{10}CFU/mL$ reduction $(0.93{\sim}3.73log_{10}CFU/mL)$ in dirty condition. Eleven hundred ppm of hydrogen peroxide was evaluated as weak sanitizer and disinfectant due to their $0.99{\sim}4.79log_{10}CFU/mL$ reduction on both clean and dirty conditions. Consequently, ethanol, iodine (25 ppm), chlorine (200 ppm), quaternary ammonium, acid and peroxide acetic acid were thought to be effective sanitizer and disinfectant against V. parahaemolyticus.

  • This study was conducted to evaluate the daily intakes of propyl gallate, EDTA (ethylenediamine tetra acetate), and erythorbic acid for average consumers by age group and the intake of high consumers ($95^{th}$ percentile) in Korea. The average intake of EDTA was $1.14{\mu}g/kg{\cdot}bw/day$, and 0.0% of the ADI (acceptable daily intake) established by JECFA (Joint FAO/WHO Expert Committee on Food Additives). The $95^{th}$ percentile intake of EDTA was $141.24{\mu}g/kg{\cdot}bw/day$ (5.6% of ADI). The average intake of erythorbic acid was $16.93{\mu}g/kg{\cdot}bw/day$, and the 3-6 year-old group had the highest consumption ($58.43{\mu}g/kg{\cdot}bw/day$), which was <1.0% of the ADI established by the EU (European Union). The $95^{th}$ percentile intake of erythorbic acid was $1,320.31{\mu}g/kg{\cdot}bw/day$ and 22.0% of the ADI. In conclusion, daily intakes of propyl gallate, EDTA, and erythorbic acid in Korea were at safe levels in all age groups and also in high consumers.

  • The 6th Worldwide Air Transport Conference was held in Montreal in March 2013 under the auspices of ICAO. This conference, which has been held every ten years, is dealing with virtually every issue of international air transport, and aiming at updating ICAO policy in order to ensure long-term growth of international civil aviation. Last conference which took place in 2003 focused on the liberalization of air transport, and the 6th conference shifted its focus from whether to push for liberalization, to how to implement it. The main agenda items for the 6th conference was liberalization, safeguards, ownership, fair competition, airports and air navigation facilities, charges, and ICAO policy. The liberalization, and in particular progressive liberalization has been a main theme over the past decades. In the process leading to liberalization, there needs to be the expansion of market access, easing regulation on ownership and control of airlines. Furthermore, the provision of enough infrastructure such as airport and air navigation facilities may be contributing factor to remove impediments to liberalization. However, out of concern as for undermining interests of consumer and the weak, when liberalization is proceeding in a sudden and radical manner, there should be safeguards so as to ensure market participation by developing countries, consumer protection, and economical and transparent decision on taxes and charges. Fair competition which differs from promoting competition in the market, is a policy in order to protect the weak players and consumers from monopoly and oligopoly. The Korean delegation submitted 3 WPs (WP/85, 86 and 87) and 1 IP, and presented WPs, at the conference, which were a lot compared with previous occasions. A paradigm shift was emphasized to expedite the process of liberalization at the 6th conference. The reality is that with many previous recommendations to stress the importance of liberalization, and to urge States to change their attitudes, the pace of the liberalization has been very slow and staggering. The liberalization of air transport will contribute to the growth of air transport and related industry, to create new employment, promoting tourism and regional development, and further to facilitating mutual understanding and exchange, which will also lead to making a barrier-free world. In this context, it is expected that the next conference will also evaluate the on-going process of liberalization.

  • To investigate the change of perception after weight management education in elementary, middle and high school students, a survey was conducted. Same questionnaire was administered twice, before and after weight management education, to 426 students at 9 schools in Seoul area. The mean height, weight and body mass index were 145.5$\pm$8.0cm, 40.0$\pm$8.3kg, 18.6$\pm$3.0 for elementary school students, 160.1$\pm$5.2cm, 50.2$\pm$7.3kg, 19.5$\pm$2.4 for middle school students, and 162.2$\pm$5.0cm, 52.2$\pm$6.4kg, 19.8$\pm$2.3 for high school students, respectively. Before education, their preferred weight and perceived healthy weight was 35.4kg and 37.0kg among elementary school students, 44.8kg and 46.5kg among middle school students, and 47.3kg and 48.9kg among high school students, respectively. Differences between their present body weight and their preferred weight and/or perceived healthy weight appeared to be 4.5kg and 2.9kg in elementary school students, 5.6kg and 4.0kg in middle school students, and 5.1kg and 3.3kg in high school students, respectively. After administering education, the differences decreased to 2.5kg and -0.2kg in elementary school students, 4.2kg and 2.7kg in middle school students, and 4.3kg and 2.0kg in high school students, respectively (p<0.01). And their perception on own body shape was investigated using 5 point scale ('too lean' to 'too fat', 1 to 5) before and after education. The mean values changed from 3.1 to 2.8 in elementary school students, from 3.3 to 3.0 in middle school students, and from 3.4 to 3.2 in high school students (p<0.01). Their satisfaction with own body weight was monitored using 5 point scale ('very satisfied' to 'very unsatisfied', 1 to 5), also. The mean values changed from 3.0 to 2.7 in elementary school students, from 3.6 to 3.2, in middle school students, and from 3.8 to 3.4 in high school students (p<0.01). In the evaluation of their nutrition knowledge about weight control using 10 item quiz, before and after education, the mean quiz score was changed from 6.3 to 7.0 in elementary school students, from 7.0 to 7.9 in middle school students, and from 7.5 to 8.1 in high school students (p<0.01). In summary, nutrition education on weight management improved the subject's perception on perceived healthy weight and own body shape, and satisfaction with present body weight. This result suggests that nutrition education program should incorporate strategies to change incorrect beliefs and knowledge regarding weight control. Onto this, weight control education for students should start from their early age, be repeated periodically and consistently, and focus on the harmful effects of excessive weight loss and information on the practical and scientific ways of weight management.

  • The influence of different storage temperature and packaging methods on plain dried anchovy were investigated. When plain dried large anchovy (DLA) was stored at $-20^{\circ}C, 5^{\circ}C and 2^{\circ}C$, the lipid oxidation was rapidly progressed with the increased temperature. When DLA was stored at $25^{\circ}C and 5^{\circ}C$, peroxide value (POV) reached to maximum on 4 days and 20 days, respectively, while POV increased progressively during storage at $-25^{\circ}C$. The degree of lipid oxidation was progressed the fastest in DLA packed in polyethylene film, followed by packing with oxygen absorber and packing in vacuum. The fatty acid composition of total lipid in DLA revealed $52.3{\%}$ in polyenes, $29.2{\%}$ in saturates and 1$8.5{\%}$ in monoenes, and the major fatty acids were 22 : 6, 20 : 5, 16 : 0, 16 : 1 and 18: 1. Saturates were increased with the rise of storage temperature and prolonging the storage period, while polyenes were decreased. The changes of fatty acid composition was retarded at lower temperature. And the changes of fatty acid composition were the lowest in DLA by vacuum packing, followed by packing with oxygen absorber and packed in polyethylene film. The contents of highly unsaturated fatty acid of polyenes were decreased remarkably in proportion to the progress of lipid oxidation, while saturates were increased.

  • In order to resolve the problem of change in global climate which is worsening as days go by and to preemptively cope with strengthened restriction on carbon emission, the government enacted 'Framework Act on Low Carbon Green Growth' in 2010 and selected green technology and green industry as new national growth engines. For this reason, the necessity to use the un-utilized waste heat across the whole industrial system has become an issue, and studies on and applications of recycling in the agricultural and fishery fields such as cultivation of tropical crops and flatfishes by utilizing the waste heat and thermal effluent generated by large industrial complexes including power plants are being actively carried out. In this study, we looked into the domestic and overseas examples of having utilized waste heat abandoned in the form of power plant thermal effluent, and carried out economic efficiency evaluation of sturgeon aquaculture utilizing thermal effluent of Yeongwol LNG Combined Cycle Power Plant in Gangwon-do. In this analysis, we analyzed the economic efficiency of a model business plan divided into three steps, starting from a small scale in order to minimize the investment risk and financial burden, which is then gradually expanded. The business operation period was assumed to be 10 years (2012~2021), and the NVP (Net Present Value) and economic efficiency (B/C) for the operation period (10 years) were estimated for different loan size by dividing the size of external loan by stage into 80% and 40% based on the basic statistics secured through a site survey. Through the result of analysis, we can see that reducing the size of the external loan is an important factor in securing greater economic efficiency as, while the B/C is 1.79 in the case the external loan is 80% of the total investment, it is presumed to be improved to 1.81 when the loan is 40%. As the findings of this study showed that the economic efficiency of sturgeon aquaculture utilizing thermal effluent of power plant can be secured, it is presumed that regional development project items with high added value can be derived though this, and, in addition, this study will greatly contribute to reinforcement of the capability of local governments to cope with climate change.

  • The rapid digitalization across all aspects of society since 1990 led to the digitalization of cartoons. As the medium of cartoons moved from paper to the web, a powerful visual culture emerged. An encounter between cartoons and multimedia technologies has helped cartoons evolve into a video culture. Today cartoons are no longer literate culture. It is critical to pay attention to cartoons as an "expanded fest" and as visual and video culture with much broader significance. In this paper, the investigator set out to diagnose the current position of cartoons changing in the rapidly changing digital age and talk about future directions that they should pursue. Thus she discussed cases of changes from 1990 when colleges began to provide specialized education for cartoons and animation to the present day when cartoon and Multimedia Comics fests exist in addition to the digitalization of cartoons. The encounter between new technologies and cartoons broke down the conventional forms of cartoons. The massive appearance of artists that made active use of new technologies in their works, in particular, has facilitated changes to the content and forms of cartoons and the expansion of character uses. The development of high technologies extends influence to the roles of appreciators beyond the artists' works. Today readers voice their opinions about works actively, build a fan base, promote the works and artists they favor, and help them rise to stardom. As artist groups of various genres were formed, the possibilities of new stories and texts and the appearance of diverse styles and world views have expanded the essence of cartoon texts and the overall cartoon system of cartoon culture, industry, education, institution, and technology. It is expected that cartoons and Multimedia Comics will continue to make a contribution as a messenger to reflect the next generation of culture, mediate it, and communicate with it. Today there is no longer a distinction between print and video cartoons. Cartoons will expand in every field through a wide range of forms and styles, given the current situations involving installation concept cartoons, blockbuster digital videos, fancy items, and characters at theme parks based on a narrative. It is therefore necessary to diversify cartoon and Multimedia Comics education in diverse ways. Today educators are faced with a task to bring up future generations of talents who are capable of leading the culture of overall senses based on literate and video culture by incorporating humanities, social studies, and new technology education into their creative artistic abilities.

  • This study was carried out to investigate the effects of jujube extracts on intestinal microflora, along with their antioxidant activities, according to extraction method. The antimicrobial activities of the extracts were measured using the agar diffusion method with a jujube extract concentration of 50 mg/mL. Neither the first nor second jujube extracts were inhibitory against the tested intestinal bacteria. However, water extracts of jujube significantly enhanced the growth of lactic acid bacteria, especially Bifidobacterium bifidum and Bifidobacterium adolescentis. Total phenol compounds and flavonoid compounds were higher in the 1st than in the 2nd water extracts. The EDA values of both water and ethanol extracts increased in proportion to the extract concentration. The 1st water extract showed the highest value among all the others, which was 85.60% at the concentration of 0.05 mg/mL. Furthermore, the 1st water extract showed stronger antioxidant activity than the other samples with an activity of 679.91 mg AA eq/g. These results support the potential use of jujube water extracts as a functional food component and a valuable resource for the development of nutraceutical foods, to increase the growth of Bifidobacterium spp. in the human intestine.

  • This study was carried out to investigate the management and support system affecting to the occupational health nursing services(OHNS) provided in group occupational health agencies(GOHA). Questionnaire was developed and distributed to 82 nurses who were working in GOHA and who agreed to participate in the survey. The results were as follow: 1. OH nurses responded were mostly in the age of twenty to thirties(89%), married(73.7%), technical college graduates(88.9%), worked in hospital(85.4%) and participated more than 1 year in group occupational health services (96.3%). 2. Fifty eight point four percent of the OH nurses worked in number of workplace more than 30 to less than 60 in the OHNS form. The figure of workplaces undertaken by nurses was ranged greatly from 9 to more than 100. Number of employees who cared by nurses were mostly under 5,000 peoples in 93.3%. The types of industry was mostly manufacturing and located in the order of factory complex area, suburban, urban and others. 3. Most OH nurses(87.8%) were fully involved in the OHNS for the SSE. Their working days to visit SSE was 5 days per week(77.8%) and one day in the GOHA at 41.3%. 4. The OH documents using by nurses were found in more than 23 different types. However, they were largely summarized in the types of 'Workplace Health Management Card', 'Personal Health Counselling Card', 'Daily Health Management Report', 'Visiting List of Workplace' and 'Sick Employee List'. 5. The items of laboratory test provided by GOHA were mostly achieved in the purpose of basic health examination. They were used to be the blood pressure check(98.8%), blood sugar test (98.8%), urine sugar and protein(91.4%), SGOT and SGPT(85.3% each), cholesterol (82.9%), hepa vaccine immunization(82.9%), r-GPT(81.7%), hemoglobin(79.3%) and triglyceride(75.5%). 6. The OH nurses(92.7%) followed the work pattern to visit the GOHA before and after small-scale enterprises(SSE) visit by car driven by nurses in 74.3%. They were payed by GOHA for transportation fees in certain amounts. However, nurse is the main person(75.0%) who covers up in case of traffic accident. If the GOHA has no transportation regulation for the formal workplace visit, data showed that nurses had been responsible to take charge(31.7%). 7. The personnel manager who takes in charge for nursing services was 'nurse' in 61.7% and 41.2% worked as the final decision maker related to nursing work. The OH nurses' opinions about factors affecting to the management were classified in the four areas such as 'Nature(Quality) of health professional'. 'Content of OHNS', 'Delivery system of the GOHS', and 'Others'. The factors were indicated highly in 'Authority as health professional', 'Level of perception of director on the OH' and 'Physical work condition for OHNS'. The things that this study suggests in the recommendation would be summarized in such as the management and supporting system working for SSE in the OHNS is necessary to reform thoroughly. The reconsidered aspects might be in the matters of number of workplaces undertaken by nurses, development of effectively practical health documents, preparation for guideline of the laboratory test in the workpleces, establishment of convenient and encouraging support system and cooperation between other health professionals with respect and skill.

  • The home health care industry has grown rapidly and can be expected to continue to grow in the foreseeable future. Home health care refers to the practice of nursing applied to clients with a health condition in the clients place of residence. clients and their designated care givers are the focus at home health nursing practice. The goal of care is to initiate. manage and evaluate the resources needed to promote the clients optimal level of well-being and function. Nursing activities necessary to achieve this goal may warrant preventive maintenance and restorative emphases to prevent potential problems from developing. Many project program were suggested home health care model for Korea's health care system and policy direction for expansion and establishment of home health care .But the aim of this paper is to provide on overview for theoretical frame work in home health care. Theories and conceptual frameworks or models are important nursing because they define and guide the boundaries of professional practice and identify key nurse-patient-caregiver relationships that emerge with caring. Following is the research with an investigation of the literature review in the University of Arizona international medline database, In conclusion, are as followers: First, many nursing theorists have had a tremendous impact on nursing practice. the following highlights those nursing theorists that are particularly helpful in understanding home health care. 1. Florence Nightingale : Our earliest theoretical legacy. Nightingale's believes are reflected in basic infection control practice such as hand washing and infectious waste disposal and are key nursing interventions in home care. 2. Martha Roger's :Science of unitary human beings theory. Rorger's believed that the focus of shared. non invasive healing modelities is the human environmental field rather than direct physical care. These modelities continue to evolve as our awareness (reflecting greater diversity, faster rhythms, motions, and ways of knowing) transcends time and space, allowing individuals to get in touch with their integral nature of unbroken wholeness. On people as ever changing energy fields have special relevance in home care especially with hospice and palliative care applications. 3. Madeline Leininger's; Transcultural nursing theory. Home care nurses move through a variety of communities and often care for patients from different cultural back grounds. Therefore Leininger's work has a good that with home care because home care nursing practice is very culturally focused. 4. Dorothea Orem's : Self care deficit theory. Orem's theory views care as something to be performed by both nurses and patients. The role of the nurse is to provide education and support that help patients acquire the necessary activities to perform self-care. Orem's theory is foundational to have care because it begins to truly acknowledge the role of the patient in managing his or her own health. which is referred to as self-care. 5. Margaret Neuman's; Health as expending consciousness theory. Neuman believes that health compasses disease and reflects an underlying pattern of person-environment interaction. A key application of 'Neuman's work to home care is for nurses to understand that health and illness do not necessarily exist at opposite ends of a continuum. 6. Jean Watson's: Theory of human caring. Watson's theory of human caring in nursing proposes human caring as the moral ideal of nursing. Nurses participate human caring to protect, enhance and preserve humanity by assisting individuals to fing meaning in illness. pain and existence and to help others gain self knowledge. self control. and self healing such thinking lends richness to theory development. as well as clinical practice in home care. Second, Robin Rice : Dynamic self determination for self care. (A theoretical framework for home care) Dynamical self determination for self care can be useful to home care nurses in a variety of ways. As research tool it can be reflected in the interview process when the home visit. The home care nurse's role is that of facilitator of patient self-determination for self care through numerous strategies. including patient education and case management.
