Purpose: The purpose of this study is to extend the knowledge about the textbook, Public Health Nursing Textbook (in Korean, Gongjungwisaeng Kanhohak) which is published in 1933 by the Nurses' Association of Korea. Methods: Public Health Nursing Textbook was investigated from the cover page to the last page and compared with two original books and other nursing books published in modern Korea. Results: Public Health Nursing Textbook was the forth published Korean nursing textbook and the first published Korean public health nursing textbook. Rosenberger, a missionary nurse from USA, Lee Keumjeon, Korean public health nurse who studied in Canada, and other Koreans were in charge of translation, etc. It is a user - friendly book written mainly in Korean (Hangul) with Chinese characters and included the English table of contents, preface and back cover. Most of its contents were extracted and translated from two original books, one is Public Health Nursing by Mary Gardner and the other is Personal Hygiene Applied by Jesse Williams. It is worth noting that the book not only introduced the public health nurses's activities across the country, but also focused on the information necessary for common health problems at that time. Conclusion: From the Public Hygiene and Nursing, it can be seen that public health nurses had been independently educated since Imperial Japan's colonial period, and public health nursing was growing as a independent field in Korea.

This study performed microbiological hazards analysis in raw food materials, cooking processes, kitchen staff, utensils, and the environment in order to obtain contamination levels of S. aureus in school foodservice operations. S. aureus was not detected in cooked foods offered by the foodservice operations; however, it was found in raw food materials prior to cooking. In the case of vegetables, S. aureus was detected in washed mung bean sprouts, parboiled mung bean sprouts, and bellflower roots both before and after disinfection, at levels of 2.2, 1.0, 1.0, and 1.0 log CFU/g, respectively. For processed foods, S. aureus was detected in one sample of packaged bean curd as well as in mung bean jelly cake at the level of 1.5 log CFU/g. For meat products, S. aureus was detected in beef brisket and chicken at levels of 2.3 and 1.3 log CFU/g, respectively. To determine microbiological hazard data for the hands and gloves of cooking personnel, the staff members were divided into two groups: a group presenting Enterobacteriaceae or coliforms, and another group presenting neither Enterobacteriaceae nor coliforms. The results showed that S. aureus was detected on the hands of staff in each group at levels of 2.0 and 2.1 log CFU/hand, respectively, and at 1.8 and 0.0 log CFU/hand on the gloves of staff in each group, respectively. Among kitchen utensils, as an environmental factor in school foodservice operations, S. aureus was detected on meat knives, mixing bowls, and dish cloths at levels exceeding 1.0 log CFU/hand.

하수관거는 생활환경의 개선, 공중위생, 침수방지 공공수역의 수질보전 및 건전한 물 순환 등을 구축하기 위하여 반드시 필요한 도시기반시설이다. 이러한 하수관거는 시가지의 하수를 배제, 처리하여 공공수역의 수질을 보전함으로서 생활환경을 개선하고, 우수를 신속히 배제함으로써 도시재해를 방지하는 등 2가지 기능을 갖고 있다. 지금 현 상 하수도 시스템은 우수, 하수나 둘 다 무조건 하수처리장으로 유하하여 처리하는 실정이다. 이러한 시스템에서는 평상시에는 문제가 없으나 강우 시에 한 번에 많은 우수가 하수 처리장으로 유하되어 하수 처리장의 처리 능력이 초과 되어 오히려 역효과를 일어 날 수 있고, 하수처리를 할 때 필요한 세제 및 재료들이 추가로 더 사용되기 때문에 정부의 국고 낭비가 되고 있는 실정이다. 그래서 본 과제에서는 이러한 단점을 보완하기 위하여 수 처리를 위한 다목적 컨트롤러 시스템을 설계 및 제안한다. 그 결과, 하수관거의 유량 및 수질을 검사 하여 하수일 경우에는 하수처리장으로 유하하고, 깨끗한 수질일 경우에는 바로 공공수역과 하천으로 흘려보내어 하수 처리장의 불필요한 처리능력에 대해 감소시킬 것이다. 추가로 각 디바이스에서 유 무선 통신으로 인한 디바이스에 대한 모니터링이 가능하고 데이터베이스에 항상 저장하기 때문에, 디바이스에 대한 관리가 쉬워지며, 관리에 대하 관리비를 줄 일 수 있기 때문에 1석 2조의 효과를 거 둘 수 있을 것이다.

Protective efficacy of trivalent Salmonella inactivated vaccine containing Chlorhexidine-inactivated S. Enterltidis (SE), S. Typhimurium (ST), and S. Gallinarum (SG) strains, was evaluated in this study. A total of 70 brown nick layers were divided into 7 groups, A to G, containing 10 hens per group. All hens in groups B to D were intramuscularly immunized with approximately 7×10⁸ cells (3×10⁸ cells of SE+1×10⁸ SE+1×10⁸ cells of ST+3×10⁸ cells of SG) of the trivalent vaccine in 0.5 mL of PBS. All chickens in groups E to G were injected with sterile PBS. All hens of groups B and E, groups C and F, and groups D and G were orally challenged with approximately 2 ×10⁹ CFU of wild-type SE, ST, and SG, respectively. Serum IgG titers and CD3⁺CD4⁺ T-cells, and CD3⁺CD8⁺ T-cells levels of groups B to D significantly higher than those of group A. In addition, all animals in groups A to C, E and F showed no clinical symptoms and survived after the virulent challenges, whereas one chicken in group D died and all chickens in group G died following the challenge. The protection against wild-type SE and ST in liver, spleen, cecum, and cloaca of groups B and C chickens was significant effective as compared with those in groups E and F. These indicate that the trivalent inactivated vaccine can be an effective tool for prevention of Salmonella infections by inducing robustly protective immune responses and cellular immune response in chickens.

The purpose of this study was to evaluate the usefulness of dental hygiene education curriculum such as oral prophylaxis, preventive dentistry, public oral health, oral health statistics, oral health education in the public oral health service performance. Questionnaire survey was posed to 96 dental hygienists working in health centers and health sub-centers. The relativity among frequency of task, usefulness, importance, and reinforcement of the education curriculum in the health centers, and the effect of current dental hygiene education curriculum on public oral health service were studied. The results were follows; 1. Sealant was performed the most frequently in the health centers and health sub-centers, and it was also the most useful content in the education curriculum. And the tooth brushing method was considered the most important in the curriculum. Therefore, oral health education was considered as factor which required the most reinforcement. However, the issues of school water fluoridation and water fluoridation in the public oral health were barely brought up as a matter of subject. 2. In the relationship between the frequency of task and the usefulness of curriculum, it showed that the more frequency of task was more useful. In the relationship between importance and reinforcements of curriculum, it showed that the more importance of the education curriculum requires more reinforcement. And more frequently performed task should be more strengthened. 3. According to the education course hours, current education curriculum course hours were 532.4 hours, which is 42.9 hours more spent than the original curriculum guideline. Lecture hours were 205.4 hours, which is 50.6 hours less, and the practice hours were 327 hours, which is 93.5 hours more than the original curriculum guideline. 4. Because of the insufficient course hours of curriculum compared to the frequency of the task, the oral health education, oral prophylaxis, and preventive dentistry should be reinforced more than now. But the oral health statistics and public oral health curriculum were not only emphasized, but also any reinforced compared to other tasks.

The purpose of this study was to examine the awareness of dental hygienists about on-the-job training in public health sector in an effort to stir up their on-the-job training(OJT) and to facilitate the planning of successful educational programs. A survey was conducted nationwide for two months in October and November 2006, and the answer sheets from 811 dental hygienists were analyzed. The findings of the study were as follows: 1. 40.7 percent of the dental hygienists investigated never underwent OJT geared toward public officials, which wasn't linked to oral health. 2. As for the experiences of professional oral health education(or OJT) as members of local public dental clinics by service term, 64.9 percent of the dental hygienists who had worked for less than 10 years never received that kind of education, and 70.5 percent of those with a 15-year or more career received that education just once(p<0.05). The dental hygienists who received that education viewed it favorably, as they found that to be conducive to their job performance. In the event of those who didn't receive that education, a lack of chance to do that was the most common reason. 3. In regard to motivation of receiving professional oral health education(or OJT), the largest rate of the dental hygienists who stood at 71.9 percent received that education voluntarily in pursuit of self-development and better job performance. The training programs provided by the oral health division of the Ministry for Health, Welfare and Family Affairs were excluded in this study. As to educational spending by the dental hygienists or their employers over the past two years, 56.9 percent paid 100 thousand to less than 500 thousand won. 46.6 percent never paid for that, and about 15.5 percent received education at their own expenses. Concerning the form of OJT, lectures were provided to 50.3 percent. 4. The dental hygienists who worked in local public health clinics hoped for more intensive and better education and training related to oral health projects.

The purpose of this study was to investigate the distribution of microorganisms and the degree of contamination in the air of the dental clinics and to offer basic data as to the contamination of medical equipment and the prevention of the clinics. With this in mind, the researcher gathered air samples from the waiting rooms and medical offices of nine dental clinics in the city of J, South Korea with the use of a method of natural inattention and an air sampler and cultivated the samples on the plain table and drew from it bacteria falling and separated and sorted out the colony with the help of ATB and detected the distribution of the germs. The results are following, The number of bacteria falling in the air of the dental clinics was less than 10(CFU/Plate) with the exception of one dental clinic. This implies that they fit in with standards for hygiene. The number of bacteria falling in the air of the medical offices was less than 10(CFU/Plate) with the exception of one dental clinic. This implies that they fit in with standards for hygiene. The survey on the detection of staph. aureus reveals that all the dental clinics with the exception of B dental clinic proving to be positive had non-pathogenic staphylococci detected. The survey on the detection of pathogenic gram negative bacilli indicates that all the dental clinics but one were none detected. The survey on the distribution of germs shows that germs in 7 out of 9 dental clinics were none detected, and that they in four out of 9 waiting rooms were none detected. All the germs detected in the others were mostly non-pathogenic. The study shows that all the subject dental clinics but one were hygienically controlled and that there was a difference in accordance with cleaning and sterilization. This means that dental clinics should be equipped with systematic programs for cleaning and sterilization designed to prevent infection.

The World Health Organization(WHO, 1998) and the United States Environmental Protection Agency (USEPA, 1992) recommended $2{\mu}\;guranium/{\ell}$ in drinking water as a guideline. The Korea Institute for Environmental Research recently reported that the radioactive pollution in ground water was almost negligible In Korea$(1999\~2002)$. Cs were cast into beads(2mm in wet form) and treated with hexamethylene diisocyanate for stability in acidic aqueous solution through cross-linking of the beads surfaces. The removal study was carried out in a static batch system and a flow system. In the static system, a certain amount of sample water was confined in a vessel and beads(dry weight 0.5g) were packed into it in order to adsorb uranium for a certain period of time. Afterwards the remaining uranium in water vessel was determined by inductively coupled plasma mass spectrometry. The effective pH range was 4 to 8. The smaller the size of beads, the better the removal efficiency. Furthemore, the lower the flow rates, the higher the removal efficiency. The results showed that chitosan beads can be effectively used for the removal of uranium contained in water.
