Objectives: In this paper, the survey on internet usage patterns of health consumers was conducted and analyzed in order to determine internet health information assessment criteria for providing correct consumer health information on web-sites. Methods: By using a survey questionnaire with 16 questions on general information and 20 questions on internet health information, data were collected from September 16 to 25, 2005 from 476 participants through an internet web site, http://www.hp.go.kr. Frequency analysis, t-test, and multiple regression were used in order to analyze the difference in assessment criteria, factors influencing assessment criteria, factors influencing user satisfaction, etc. Results: General characteristics of the study population were: the persons over age 40 were the smallest age group; women were accounted for 74.2%; and the persons with average income were the largest income group; and the persons with average health status were the largest health group. Most widely used health information were: exercise, disease, and diet, in order. There was significant difference(p=.001) in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. There was no significant difference in other assessment criteria. We also found that contents of websites and easy to use were more important factors than elucidation of information providers and information sources including speciality of information in quality assessment criteria of internet health information. Discussion and Conclusion: Results of this paper were compared with the previous studies from the literatures. Contrary to the previous studies in the literature, there was significant difference in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. In order to apply the study results to develop health contents for consumer, there is a need for further upgrade the proposed assessment criteria based on expert opinion.

It is widely observed in the Korean broadcasting production industry that unfair trade practices occur either when the drawing up a contract is ill-timed, when the contract's stipulations do not adequately cover possibilities in reality, or when the contract is simply breached. In particular, the most prevalent cause of the breach of contracts lies in the broadcasting production practices. Hence, systematic efforts should be made to improve the daily practices of the production industry by ensuring that the whole production process is carried out by contract. In order to achieve this, the following are suggested: i) A preliminary contract is to be made prior to the main one. ii) A standard production contract, which can be used as a template for other sub-contracts such as writing contracts, acting contracts, employment contracts, and so on, needs be introduced. iii) The standard contract should stipulate the obligations of the personnel from broadcasting companies, the recognition of the rights of production companies that created formats, and the boundary of the autonomy that production companies can exercise during production, in particular. iv) Prohibitive provisions are to be introduced into the Broadcasting Law in order to limit the causes for unfair trade practices.

CIMT(Constraint Induced Movement Therapy) is to improve the function and use of damaged upper limbs by not only confinement of unaffected limbs' exercise but also inducement of affected limbs' one. The purpose of the study is to verify the effect of CIMT by means of motor behaviour test and immunohistochemistry, using animal models. This study was analyzed using 40 male Sprague-Dawley rats as the experimental groups and 40 ones as the control groups. The rats were divided into two random groups : one group as an experimental group which was operated on under anesthesia and removed somatomotor regions with CIMT and the other as the control group without CIMT.Postural Reflex Test, Beam Walking Test, Limb Placement Test and Immunohistochemistry were run on the day 1, 3 , 7 and day 14 following surgery to each 10 rat. As a result, this study demonstrates that CIMT might be an effect method to verify the plasticity of central nervous system as motor behaviour test made all high scores (p<.05) and BDNF was high too in experimental groups.

Diabetes is a type of metabolic disease presented by high blood sugar and that leads to significantly decrease the quality of life causing various symptoms. It is essential to manage a systematic menu for preventing such diabetes even though there are some ways for it including diet, physical exercise, medicinal prescription, and so on. This study proposes a smart phone based personalized menu management system for achieving the systematic diabetes management. At the present time almost menu systems for diabetes patients are subjectively prescribed by dietitians or doctors and that does not reflect current situations and personal preferences. The system proposed in this study provides the menu for diabetes patients according to season, weather, time, and personal preferences. In particular, the recipe and personalized menu for patients can be provided without limiting any time and location based on smart phone services, and its menu can easily be changed or selected by the phone.

Exercise such as walking is helpful to manage one's own weight and to counter life habit diseases such as obesity. Calorie consumption is usually calculated based on the distance walked. One way to measure the distance is by using steps and stride length. Most pedometers, including some applications in smart devices, are inaccurate, because they use a common value as the average stride length, even though each person has a different stride length. Moreover, the stride length differs depending on the walking pace, which will further increase the error. To address this, in this paper, I classify paces into three categories. Following that, I introduce a customized measurement of stride length, which is calculated based on the stride length corresponding to each pace category after obtaining x, y, z values from a 3-axis accelerometer in the smart device. In addition to this, I developed an application running on the smart device designed for the proposed measurement of stride. I have conducted three experiments for the assessment of the proposed measurement. In conclusion, I confirmed the effectiveness of this system.

This study has a purpose to devise an education program in relation to Gerontology and geriatrics applicable to Korean nurses through literature review and analysis of education programs utilized by the Geriatric Education Centers (GECs) of USA. Educational contents on gerontology and geriatrics are very diverse in precedent literatures. The education programs of GECs for health care personnel are equally very diverse. Among educational contents, subjects considered important are age-related changes, health problems of the aged, pharmacology, death, fall and osteoporosis, delirium, dementia, depression, urinary incontinence, communication with elderly. Methods used in education program are mainly seminar, workshop and lecture through internet. In addition, case study, small-group discussion and conference are also adopted. The program proposed in this study for nurses in relation to gerontology and geriatrics consists of 32 hours' education; 6 hours for age-related changes, 10 hours for health problems of the elderly, 14 hours for health problems in old age and 2 hours of communication technique. Educational method proposed is to utilize lecture through internet, direct education, workshop, practical exercise, case study and role play in parallel. This study proposed an education program on the basis of precedent literature and the program of GECs. Therefore, it is desirable to develop in the future more practical education program applicable to and required in practicing fields. Of course, this development needs to be based on nurses' educational needs by field in relation to gerontology and geriatrics.

The inhibitory effect of IgY against Vibrio parahaemolyticus and Vibrio vulnificus responsible for seafood-borne diseases was investigated in this study. Water-soluble fractions (WSF) of protein containing IgYs were isolated from the egg yolk of hens initially immunized with formalin-inactivated V. parahaemolyticus or V. vulnificus. Protein, total and specific IgY contents of the WSF were determined. The inhibitory and protective effects of IgYs on the growth of V. parahaemolyticus and V. vulnificus were assayed in liquid medium and in mice. IgYs showed high affinity to their corresponding antigens with high titer from day 28 onwards. Protein contents and total IgY concentrations remained stable throughout the immunization period, whereas specific IgY concentrations increased steadily and reached a plateau at day 49. Specific IgY powder (150 mg/ml) significantly inhibited further multiplication of both V. parahaemolyticus and V. vulnificus in liquid medium as compared with the control IgY. The bacteria count in mice feces was lower in mice pretreated with specific IgYs than in those pretreated with PBS or control IgY. Higher survival of mice was observed in the experimental groups pretreated with either anti-V. parahaemolyticus (75% survival) or anti-V. vulnificus (87% survival) IgYs, compared with those in the control groups pretreated with PBS or nonspecific IgY. All mice in the control groups died within three days after bacteria inoculation; hence, the protective effect of specific IgYs against infection caused by V. parahaemolyticus and V. vulnificus was demonstrated.
