The aim of this study was to provide practical information regarding career exploration to dental hygiene students. This study interviewed 15 senior dental hygienists (graduates of Y University Dental Hygiene program) who have worked in non-clinical fields for about three months from January 14, 2014 to April 28. The most frequently mentioned pieces of information that the senior dental hygienists wanted to convey to dental hygiene students were as followed. Contrary to popular belief, clinical experience was also required in non-clinical fields as the importance of clinical experience was quite often and widely emphasized and applied in such fields. High academic excellence and clinical performance were expected of junior dental hygienists and the senior dental hygienists expressed their hope for their juniors to pioneer new fields and areas of work that a dental hygienist can do. Most of the senior dental hygienists pointed out that to develop technical tools for career exploration as early as possible, such as during undergraduate years and to think about which career path to take, whether it is clinical or academic were significantly important factors for desirable career outcomes. Based on the results of this study, undergraduate dental hygiene students should be provided with opportunities to consider and explore various career paths during their undergraduate years and to communicate with their seniors for hands-on experience-based advices. This would in turn broaden each student`s perspective beyond their knowledge or thought about the professional filed of dental hygiene. It was found that the majority of the senior dental hygienists agreed that their clinical experience was the source of their self-competence as a dental hygienist. Our study could be utilized as a valuable resource for future dental hygienists who wish to work in non-clinical fields.

In spite of the seriousness of smoking harm has been developed these days. the increase of national smoking rate and that the people in the twenties are especially leading the rise of national smoking rate is an important issue of national health. Smoking of the university students can occur health problem and cause loss of manpower and expenses in their social activity period. So then the actual state for prevention of smoking and development of a program to prohibit smoking has to be seized urgently and starting with the study of the realities of university students, the effort to find a related fluent of smoking has to be studied. Related to this, the purpose of this study is to seize the general characteristics of smoking university students and to find out the relationship between perceived stress and smoking status among smoking university students. In addition, by collating the relationship between perceived stress and smoking status among smoking university students we have the purpose to furnish the basal data of stress care, the best way to cope with stress through group training and the plan for nursing implementation to decrease the smoking rate. For this study, a survey was conducted for 204 smoking university students of 13 universities in Seoul from 9th of May to 16th of May, 2003. The collected data was analyzed by t-test, Pearson Correlation and ANOVA in the statistical packages SPSS/PC. Major findings of this study are as follows; 1. Of the 204 respondents 85.4% of them were male and 14.6% of them were female. The average age of the sample was 23.19 years old and 41.8% of them were in senior, 21.4% in junior, 16.9% in sophomore, 19.9% in freshman grade. The major motivation to start smoking was 'because of curiosity'(33.8%) and the first smoking experience was at 'senior high school' (41.9%) and at 'college' (41.9%). 2 The highest scored stress factor of smoking university students were stresses about school work. 3. 72.7% had experience to quit smoking at least one or more times. Most of the reason to keep on smoking was 'short will to quit'(51.0%) and the smoking place was usually at 'school' (41.4%). Most respondents for the number ofsmoking friends were '5 people and above' (73.2%). 4. There was a negative relationship between the general characteristics and the entire perceived stress, however, there was a positive relationship between the general characteristics and the perceived stress in 4 categories which is 'sex distinction', 'major of study', 'residence form' and' inmate'. 5. There was a negative relationship between the general characteristics and the entire smoking status, however, there was a positive relationship between the general characteristics and the smoking status in 2 categories which is 'presence of hobby' and 'number of smoking friends'. 6. There was a negative relationship between the perceived stress and the smoking status. Through this study we have seized the relationship between the general characteristics, perceived stress and the smoking status of smoking university students. There was a positive relationship between some of the general characteristics with the perceived stress and the smoking status of smoking university students. Also there was a negative relationship between the perceived stress and the smoking status.

Background: We investigated the prevalence of latent tuberculosis infection (LTBI) among the health care workers (HCWs) and analyzed its risk factors in South Korea. Methods: A standard questionnaire regarding the baseline demographics and risk factors for LTBI was given to each participant and tuberculin skin test (TST), QuantiFERON-TB GOLD In-Tube (QFT-GIT) assay, and chest radiography were performed. Results: A total of 493 participants, 152 (30.8%) doctors and 341 (69.2%) nurses were enrolled in eight tertiary referral hospitals. The mean age of the subjects was 30.6 years old, and 383 (77.7%) were female. Of the 152 doctors, 63 (41.4%) and 36 (23.7%) were positive by TST and by QTF-GIT, respectively, and among the 341 nurses, 119 (34.9%) and 49 (14.4%) had positive TST and QFT-GIT results, respectively. Overall, the agreement between the two tests was 0.22 by the chance corrected proportional agreement rate (kappa coefficient) in 493 subjects. Experience of working in tuberculosis (TB)-related departments was significantly associated with positive LTBI test results by QFT-GIT assay, not by TST. In multivariate analysis, only age was independently associated with increased risk of a positive TST result, while age and experience of working in TB-related departments (odds ratio, 2.29; 95% confidence interval, 1.01-5.12) were independently associated with increased risk of a positive QFT-GIT result. Conclusion: A high prevalence of LTBI was found among South Korean HCWs. Considering the association between the experience of working in TB-related departments and high risk of LTBI, QFT-GIT may be a better diagnostic test for LTBI than TST in HCWs.

본 실험은 카네이션의 경정배양을 통한 기내증식체계를 확립하고 기내증식과정 중 발생하는 투명묘의 발생을 억제하기 위하여 실시하였으며, 발근과 순화과정을 통합함으로써 그에 따르는 경비와 노동력을 절감할 수 있는 방안을 마련하는 한편, 기내에서 얻은 묘를 직접 재배에 이용할 수 있는 방법을 개발하기 위하여 실시하였다. 경정배양에서 생존율은 Benzyladenine (BA) 또는 Kinetin (KI) 0.1㎎/ℓ 첨가한 모든 배지에서 80%이상이었으나 그 이상의 농도에서는 농도가 증가할수록 생존율이 감소하였으며, Naphthaleneacetic acid (NAA) 또는 Indoleacetic acid (LAA) 0.1㎎/ℓ 혼합첨가시에는 2.0㎎/ℓ까지는 농도에 관계없이 모든 처리구에서 생존율이 75%이상이었다. 경정배양에서 얻은 신초의 증식배양에서 LAA나 NAA의 첨가에 관계없이 KI보다 BA를 첨가하면 신초발육이 더 좋았다. MS배지의 무기염류를 4배로 첨가한 4MS배지에서는 신초가 모두 고사하였고, 1 MS배지에서 신초의 발육이 가장 좋았다. Sucrose 무첨가 배지에서 신초의 발육이 가장 좋았다. Sucrose 무첨가 배지에서 신초의 발육은 거의 이루어지지 않았고, sucrose 20㎎/ℓ첨가배지에서 신초의 발육이 가장 좋았다. 한천보다 겔라이트 첨가배지에서 신초의 발육이 좋았다. 배지 pH는 5.0에서 신초의 발육이 가장 양호하였다. 투명화묘의 발생은 경정배양과 계대배양 전과정에서 발생하였고, 한천 또는 겔라이트의 농도를 높여주었을때에 억제되었다. 발근 및 순화단계에서 신초의 발육과 근형성은 sand, vermiculite배지에서 보다 perlite배지에서 더 좋았다. This study was carried out to establish a system for clonal multiplication and preventing vitrification in shoot tip culture of carnation. Combining the two steps of rooting and acclimatization, it may possibly reduce the cost and save the labor for clonal propagation. In addition, the plantlets raised by this one step rooting and acclimatization could be directly transferred to soil. The survival rate was over 80% in the media containing 0.1㎎/ℓ benzyl-adenin (BA) or kinetin (KI), but decreased as the concentration increased. When auxins were added in combination with cytokinins, the survival rate was over 75% regardless of the cytokinin concentration up to 2.0㎎/ℓ. When the in vitro shoots were subcultured, shoot development was better in the media containing BA than those containing KI regardless of addition of indoleacetic acid (LAA) of α-naphthalene acetic acid (NAA). Shoot development was the best in the standard MS medium(1xMS), while all the shoots on the medium containing 4 times the inorganic salts of MS medium(4xMS) died. Shoot development in MS medium free of sugar was not noticed. The MS medium containing 20g/ℓsucrose resulted in the best shoot growth. Shoot development was better on the media containing gelrite than those containing agar. The MS medium at pH 5.0 favored the shoot development. Vitrification of shoots occurred during the initial shoot culture as well as during the subculture of the in vitro shoots, but it was suppressed when the concentration of gelrite or agar in the media was increased. As the substrate for rooting and acclimatization of the in vitro shoots, perlite was better than sand or vermiculite.

Background/Aims: Westernization in many Asian countries have changed lifestyles and diets, so once rare diseases have now become prevalent. The aim of this study is to investigate the changing pattern of digestive and liver disease in Korea, from 1990 to 2006. Methods: We extracted data specific gastrointestina (GI) disease based on the International Classification of Diseases code from the in-patients records at the Kangnam St. Mary`s Hospital in 1990, 1996 and 2006. This hospital is a tertiary-care hospital in Seoul, Korea, which has a capacity of 800 beds. Results: The admission rate for GI disease increased between 1990 and 2006. Overall in-patients were 1,623 persons in 1990, 2,368 persons in 1996 and 4,166 persons in 2006. The mean age of in-patients increased as time went by. A stomach cancer was the most common diagnosis during all periods, but its prevalence has decreased. Colon cancer ranked the 7th in 1990, but markedly increased and now ranks the second. The third was a hepatocellular carcinoma. The bile duct and gallbladder cancer, pancreas and esophageal cancer ranking followed with little interval change. In cases of cancer patients, a regular admission dramatically increased for chemotherapy. The number of patients admitted with pre-malignant neoplasm of stomach and colon increased remarkably with the development of endoscopy. The liver transplant, inflammatory bowel discase, and reflux esophagitis emerged form mid-1990s with greater frequencies, yet much below the levels found in the West. The admission rate for peptic ulcer, especially ulcer bleeding remained relatively stable, despite a decreased rate for ulcer perforation. Liver cirrhosis, hepatitis, cholelithiasis with cholecystitis-cholangitis, appendicitis, hemorrhoid and gastritis all decreased. Conclusions: The stomach cancer is the leading cause of admission, despite a recent decline. Colon cancer showed a marked rise. The liver transplant, inflammatory bowel disease and reflux esophagitis were new diagnosis with an increased tendency.

Following recent advanced industrialization, the amount of polyurethane to use as thermal insulating materials, upholstery, mattresses and packing materials in automotive and furniture industry is increasing world-widely, and the number of polyurethane-producing worker will be increased. Because the numerous organic solvents are used in polyurethane-producing factory, the workers in this work site is exposed to many organic solvents. Of the organic solvents, Toluene Diisocyanate(TDI) has many hazardous effects to human. The effects of TDI on human are the irritation to respiratory mucosa and gastrointestinal symptoms. Conjunctival irritation, dermal inflammation (redness, pain, vesicular formation) and gastrointestinal symptom(nausea, vomiting. abdominal pain) are reported just after short-term exposure of TDI. TDI is known to give rise to bronchial asthma, as the immune disorder. And because of strongly volatile characteristics of TDI, it is suggested as a more injurious material to human health, especially human immune system, than other organic solvents. Bronchial asthma inducing mechanism of TDI is not clearly known, but on the analogy of TDI induced symptoms and recent studies, early-onset asthma is type I hypersensitivity reaction mediated by immunoglobulin E(IgE), and late-onset asthma is maybe type III hypersensitivity reaction by circulating IgG. And we know that the complicated human immune function is likely to move in such that mechanisms, there are not studies on immune indices evaluating the bronchial asthma-related immune function. The evaluation of change patterns of humoral immunity including IgE and IgG and cellular immunity including T-helper cell. T-suppressor cell and T-cytotoxic cell will be helpful to evaluate exposure degrees and prognosis in TDI exposed workers. Because TDA(toluene diamine) as a biological exposure index of TDI becomes the focus of interest, we know that a study on the correlation between urinary TDA and air TDI and immunological indices will make a contribution to biological effect monitoring indicies. We examined human immunity indicators such as WBC, %Lymph (percentile of Lymphocyte in WBC), %T-cell(percentile of T-lymphocyte in total lymphocyte). CD4, CD8, C3, C4, IgA, IgG, IgM, IgE in peripheral blood to evaluate the health hazard of the TDI-exposed workers. And we examined TDA to evaluate correlation between exposure and effect. Total 90 subjects was selected, 45 workers who worked in the polyurethane-producing factories as an exposed group, and 45 cases who were office workers(10 cases), other blue collors(27 cases), and medical college students(8 cases) as a control group. And the results were as follows; 1. The logarithm of IgE-Log10(IgE)±SD-in peripheral blood of a exposed group was significantly higher than a control group, 2.22 ±0.62 in case group compared with 1.98±0.53 in control group. (p<0.05) 2. IgA and IgM in the polyurethane-producing workers were 261.02±83.12㎎/㎗, 151.97 ±59.64 ㎎/㎗, respectively, and 292.77±100.45, 179.17±100.78 in control group. IgA and IgM was slightly lower in polyurethane-producing group than control.(p>0.05) 3. WBC, %Lymph. %T-cell, C3, C4, CD4, CD8, CD4/CD8 ratio and IgG in case group were 6.391.1 ea/㎖, 37.53 %, 59.54 %, 76.68 ㎎/㎗, 0.76×10(9) ea/L, 0.63×10(9) ea/L, 1.39, and 1606.29 ㎎/㎗, respectively, and 6,974.7 ea/㎖, 35.12 %, 59.64 %, 71.95 ㎎/㎗, 33.94 ㎎/㎗, 0.80×10(9) ea/L, 0.61×10(9) ea/L, 1.39, and 1581.51 ㎎/㎗ in control group. There was no statistical significance between two groups.(p>0.05) 4. In the comparison of each other companies, average of individual urinary TDA in polyurethane paint manufacturing companies is higher than that of polyurethane sponge foaming companies. And, the concentration of 2.6-TDA which is a metabolite of well-vaporized 2.6-TDI is higher than that of 2.4-TDA in the polyurethane sponge foaming companies. But, the concentration of 2.4-TDA which is a metabolite of illvaporized but well skin-absorbed 2.4-TDI is higher in polyurethane paint manufactures. 5. There were no statistical significance in the correlations between individual urinary TDA and immunologic indices.
