Objectives : There has been gradually increasing concern about the adverse health effects of electromagnetic radiation originating from cell phones which are widely used in modern life. Cell phone radiation may affect human health by increasing free radicals of human blood cells. This study has been designed to identify DNA damage of blood cells by electromagnetic radiation caused by cell phone use. Methods : This study investigated the health effect of acute exposure to commercially available cell phones on certain parameters such as an indicator of DNA damage for 14 healthy adult volunteers. Each volunteer during the experiment talked over the cell phone with the keypad facing the right side of the face for 4 hours. The single cell gel electrophoresis assay (Comet assay), which is very sensitive in detecting the presence of DNA strand-breaks and alkali-labile damage in individual cells, was used to assess peripheral blood cells (T-cells, B-cells, granulocytes) from volunteers before and after exposure to cell phone radiation. The parameters of Comet assay measured were Olive Tail Moment and Tail DNA %. Results : The Olive Tail Moment of B-cells and granulocytes and Tail DNA % of B-cells and granulocytes were increased by a statistically significant extent after 4-hour use of a cell phone compared with controls. Conclusion : It is concluded that cell phone radiation caused the DNA damage during the 4 hours of experimental condition. Nonetheless, this study suggested that cell phone use may increase DNA damage by electromagnetic radiation and other contributing factors.

Purpose: Romberg's disease manifests as progressive hemifacial atrophy of the skin, soft tissue and bone, which usually begins in the first or second decade of life. When present, atrophy may originate from the cutaneous stigmata and may become so sharply delimited by the midline. Methods: A 10-year-old girl, who had suffered from right mandibular area atrophy for 3 years, visited us and was diagnosed with Romberg's disease. The depressed lesion of the face was augmented successfully using a deepithelialized groin free flap. The superficial circumflex iliac vessels were used as the donor pedicle and the facial artery and vein were used as the recipient vessels. Results: After surgery, the flap survived well and she was satisfied with the result. Although there are various methods of facial augmentation using free flaps, this flap has some advantages. First, there is a considerable amount of fat tissue components for augmentation. Second, flap elevation with thinning is possible. Third, the donor site can be hidden. Conclusion: The groin dermo-fat free flap is a good method for the facial augmentation of Romberg's disease.

Objectives : The purpose of this study was to examine the oral health knowledge and actual oral health care of the selected subjects, their decision making about prosthetic treatment, the state and characteristics of their prosthetic treatment and their satisfaction with prosthetic treatment in an attempt to provide some information on the improvement of the quality of life related to oral health and the promotion of oral health. Methods : The subjects in this study were 250 people who received education in two different lifelong education institutions in the city of Busan. After a survey was conducted from May 23 to June 15, 2011, the answer sheets from 217 respondents were analyzed. Results : 1. As for the general characteristics of the respondents, the men(52.1%) outnumbered the women. Those who were in their 60 and up(47.5%) made up the largest age group, and the married people(65.4%) outnumbered the unmarried ones. By occupation, the company employees(20.3%) made up the biggest group. By education, the greatest group was high-school graduates(36.1%). By monthly mean income, the biggest group gained an income of 2.01 million won or more(36.9%). As to medical security, community-based insurance was most prevailing (36.9%). In terms of health promotion, the largest group worked out to stay fit(52.4%). 2. Regarding oral health knowledge, they had a good knowledge about the cause of dental caries(56.7%), but they weren't well aware of the right time for regular dental checkup(47.9%). In relation to oral health care, regular scaling wasn't prevailing(16.9%). 3. Regarding connections between the general characteristics and satisfaction with prosthesis, the less-educated respondents expressed significantly more dissatisfaction(p=0.015). By monthly mean income, those who had a smaller income were dissatisfied in general(p=0.028). Conclusions : The findings of the study illustrated that it's required to spread awareness of the importance of oral health among people in general, and that differentiated incremental oral health care should be provided for different age groups. In order to raise the satisfaction of patients with prosthesis, how to relieve their pain and anxiety and how to adjust prosthetic treatment cost properly should carefully be considered. In addition, the government should take measures to offer assistance for the low-income classes in preparation for an increase in the elderly population.

This study is aimed at examining the ethical values of EMT students. The results below are based on the revised questionnaires, which can be applicable to EMT from the original questionnaires developed by Lee(1990), with a sample of 124 students consisting of 63 first and 61 second year students, conducted November 2-8, 2001. Data were analyzed using SPSS in terms of means, standard deviations, t-test, ANOVA, Pearson's correlation coefficient. The results are as follows: 1. In the area of Human life, all subjects showed utilitarian disposition. All respondents perceived the item "When patients recognizing there is no hope for survival ask for euthanasia, it is ethically right to accommodate their opinions." as the most utilitarian item, whereas they perceived the item "When an hopeless patient is on cardiac arrest, it is ethically right to do CPR as the most deontoogical item. 2. In the area of patient relationship, all students of two groups took on deontoogical characteristics, but there were no statistically significant differences between two groups. All students perceived an item "EMT have to keep it secret if patients disclose their suicide intentions and ask for absolute secrecy" the most utilitarian item, whereas they perceived an item "Even though patients act and speak in a very rude manner, EMT people should do their best to provide care for patients." as the most deontoogical item. 3. In the area of task relationship, first year students perceived an item "Given time limitations, it is ethically right to give priority to the patients who can be rehabilitated over the patients who can't be fully recovered." as the most utilitarian item, whereas second year students perceived an item "Under no circumstances should any placebo be administered to patients." as the most utilitarian item. All students perceived an item "When EMT students see an unconscious person lying in the street, they have to give him/her emergency treatment." as the most deontoogical item. 4. In the area of coworker relationship, all students of two groups took on deontoogical disposition, but there were no significant differences between two groups. All students of two groups perceived an item "Suppose you are regarded as the person who would be promoted. However, you think that your coworker is more competent than you. In that case you should tell your supervisor about your coworker." as the most utilitarian item. First year students perceived an item, whereas second year students perceived an item "When you observe coworkers' misconduct at work, it is ethically right to ignore their misdeeds." as the most deontoogical item. 5. This study demonstrated that for the first year students, there is a correlational relationship between areas of human life and task relationship, and between areas of task relationship and coworker relationship, whereas for the second year students, there is a correlational relationship between areas of human life and task relationship. 6. In areas of human life and task relationship, there are significant differences according to attitudes toward EMT and attendance at ethics training sessions. In the area of coworker relationship, there are significant differences according to religion, attendance at ethics training sessions, and a code of ethics. Recommendations for future research, 1. Sample items to measure ethical values and the instrument tailored to the needs of EMT should be developed. 2. A longitudinal study to track ethical value changes according to the amount of work experience is needed. 3. A code of ethics and/or ethics training, which could apply in actual situations, should be implemented.

This study was conducted to inquire about the view on childrearing of university women for the purpose of building up the positive parent- child relationship and setting up preliminary parenting education program. The subjects were 137 university women who were freshmen to junior in one women's university in Seoul. Using the self-report questionnaire, data were collected from December in 1998 to March in 1999 and the contents which subjects wrote down were categorized by content analysis method. The results were as followed: 1. The age range of subjects were 20-22 years and main rearer was her mother(71.5%) 2. The view of subjects were revealed by 374 statements and then tied together 34 themes: 'exemplary parent model as a guider'(8.6%), 'determination for oneself' (8.0%), 'expression of love'(6.2%), 'humanity education'(4.8%), 'carrot and stick'(4.5%), 'respect of personality'(4.3%), 'sound living habit'(4.1%), 'conversation'(3.7%), 'regulation of greediness' (3.7%), 'supply of live experience'(3.7%), 'supply of broad and substantial vision'(3.5%), 'free choice'(3.5%), 'broad-mindedness'(3.5%), 'consideration'(3.0%), 'doing together'(3.0%), 'propriety education' (2.4%), 'pursuit of naturalness'(2.4%), 'looking for one's life'(2.4%), 'confidence'(2.1%), 'rearing by oneself'(2.1%), 'encouragement'(2.1%), 'cultivation of right sexual senses'(2.1%), 'desirable home environment'(1.9%), 'doing one's best'(1.9%), 'understanding'(1.6%), 'psychological intimacy'(1.6%), 'treat fair'(1.6%), 'pursuit of physical, psychological health' (1.6%), 'concerning'(1.3%), 'religious life'(1.3%), 'respect of individuality'(1.3%), 'cooperation' (1.1%), 'often-minded family'(0.8%), 'positive attitude'(0.8%). 34 themes were categorized by 12 categories once more: 'mature parenthood'(15.5%), 'acceptance' (11.5%), 'autonomy'(11.5%), 'pursuit of healthy life style'(9.4%), 'eagerness'(9.1%), 'making efforts'(8.8%), 'education'(8.8%), 'emotional bonding' (7.8%), 'respect'(7.2%), 'corporal punishment' (4.5%), 'supporting'(3.2%), 'composition of environment'(2.7%). In conclusion, we could expect that university women had a democratic view on childrearing with love and autonomy for a base. So we need to offer them nursing implementations such as preliminary parenting programs and parenting consulting in order to promote positive and interactional parent-child relationship by strengthening their desirable view on childrearing.

The Electro-Optical Camera (EOC) is a high spatial resolution, visible imaging sensor which collects visible image data of the earth's sunlit surface and is the primary payload on KOMPSAT-l. The purpose of the EOC payload is to provide high resolution visible imagery data to support cartography of the Korean Peninsula. The EOC is a push broom-scanned sensor which incorporates a single nadir looking telescope. At the nominal altitude of 685Km with the spacecraft in a nadir pointing attitude, the EOC collects data with a ground sample distance of approximately 6.6 meters and a swath width of around 17Km. The EOC is designed to operate with a duty cycle of up to 2 minutes (contiguous) per orbit over the mission lifetime of 3 years with the functions of programmable gain/offset. The EOC has no pointing mechanism of its own. EOC pointing is accomplished by right and left rolling of the spacecraft, as needed. Under nominal operating conditions, the spacecraft can be rolled to an angle in the range from +/- 15 to 30 degrees to support the collection of stereo data. In this paper, the status of EOC such as temperature, dark calibration, cover operation and thermal control is checked and analyzed by continuously monitored state of health (SOH) data and image data during the mission life of 3 years. The aliveness of EOC and operation continuation beyond mission life is confirmed by the results of the analysis.

이 글은 생명과학기술의 또 다른 그늘로서 유전자차별의 사회학적 함의를 조명하기 위한 것이다. 이를 위해 유전자차별과 관련된 주요개념과 세 가지 시각(예외주의, 표현주의, 인권적 담론)을 검토하고, 미국의 "유전자차별금지법(GINA)"과 우리나라 "생명윤리 및 안전에 관한 법"에 나타난 사회적 함의와 한계를 분석하였다. 또한 기존의 유전자차별에 대한 인식결과(차별인식, 차별경험, 차별의 두려움, 차별에 대한 대응)에 기반하여 향후 유전자차별의 연구 및 정책을 위한 몇 가지 함의를 제시하였다. 우선, 유전자차별에 대한 개념적 합의와 함께 인권주의 시각의 중요성이 요구된다. 둘째, 공적 영역뿐만 아니라 사적 영역에서의 차별에 대한 관심과 유전소인을 가진 인구집단의 시각을 반영한 연구가 필요하다. 셋째, 법제도적 장치뿐만 아니라 국민과 의료인들에게 유전자차별 의식을 고양하고, 유전소인을 가진 사람들을 위해 유전자차별의 두려움을 낮출 수 있는 심리사회적 대응방안이 개발되어야 한다.
