This study seeks the countermeasures for the successful organization of the social welfare labor union after examining social welfare workers' cognizance about a labor union and analyzing the major factors affecting their participation in a labor union. An analysis of social welfare workers' cognizance about the social welfare labor union. demonstrates that (1) most social welfare workers have positive opinions about a labor union organization and the participation in a labor union, (2) a great part of workers prefer forming a labor union and a professional organization together in relation to the organization of social welfare workers, and (3) the effective strategies for the organization of a labor union are in the order of the uplift of social welfare workers' consciousness, the constitution of the basic organizations which propel the formation of a labor union, and the preparation of policy countermeasures which attain the supports of clients and citizens. An analysis of factors affecting the participation in a labor union shows that the attitude toward the participation behavior (positive results), subjective norm (specific individuals), subjective norm (social constituent members), and perceived behavior control in the analysis model, male, lower position in officers, and lower educational attainment in democratic characteristics, and lower democratic and professional managements in officers and longer working hours in labor environmental conditions affect positively the participation in a labor union. These results suggest several assignments for the successful organization of the social welfare labor union. First the activities that make social welfare workers recognize the beneficial results bringing about by the participation in a labor union need to be carried out, second strategies that persuade the influential individuals to supports the participation in a labor union need to be developed, third activities that make the social constituent members understand the ethical, professional, and non-productive characteristics of social service works not to be confronted with the organization of a labor union should be pursued, fourth the organizational environments in which social welfare workers can freely participate in a labor union according to their intentions need to be made up, fifth the policy countermeasures which attain the support of social welfare workers, clients and citizens should be developed and carried out, and finally the basic organizations that effectively propel the formation of a labor union need to be constituted.

Background : Particulate matters (PM) when inhaled is known to induce pulmonary diseases including asthma and chronic bronchitis when inhaled. Despite the epidemiological proofevidence, the pathogenesis of PM-related pulmonary diseases is unclearremain poorly understood. Methods : Primary alveolar macrophages were harvested from the SPF and inflammatory rats by bronchioalveolar lavage (BAL). The cultured primary alveolar macrophages were treated with the medium only, PM only ($5{\sim}40{\mu}g/cm^2$), LPS (5ng/ml) only, and PM with LPS for 24 and 48 hours. The level of secreted nitric oxide (NO) was assayed from the cultured medium by using the Griess reaction. The cultured cells were utilized for the western blotting against the inducible nitric oxide synthase (iNOS) proteins. Immunocyto- chemical staining against the iNOS and NT-proteins were performed in cells that cultured in the $Lab-Tek^{(R)}$ chamber slide after treatments. Results : The PM that utilizein this experiments induced NO formation with iNOS expression in the cultured SPF and inflammatory rats alveolar macrophages, by itself. When the cells were co-treated with PM and LPS, there was a statistically significant synergistic effect on NO formation and iNOS expression over the LPS effect. The cells from the sham control showed minimal immunoreactivity for the NT-proteins. Significantly higher quantities of NT-proteins were detected in the PM and PM with LPS co-treated cells than from the sham control. Conclusion : Increased iNOS expression and NO formation with increased NT-proteins formation might be involved in the pathogenesis of PM-induced lung injury.

This experiment has investigated suitable methods to improve precision water content monitoring of coconut coir substrates to control irrigation by frequency domain reflectometry(FDR) sensors. Specifically, water content changes and variations were observed at different sensing distances and positions from the irrigation dripper location, and different spaces between the FDR sensors with or without noise filters. Commercial coconut coir substrates containing different ratios of dust and chips(10:0, 7:3, 5:5, 3:7) were used. On the upper side and the side of the substrates, a FDR sensor was used at 5, 10, 20, 30cm distances respectively from the irrigation dripper point, and water content was measured by time after the irrigation. In the glass beads, sensors were installed with or without noise filtering. Closer sensing distance had a higher water content increasing rate, regardless of different coir substrate ratios. There were no differencies of water content increasing rates in 10:0 and 3:7 substrates between the upper side and the side. Whereas, 7:3 and 5:5 substrates showed higher increasing rates on the upper side measurements. Substrates with higher ratios of chip(3:7) had lower increasing rates than others. And, with noise filters, the exatitude of measurement was improved because the variation and deviation were reduced. Therefore, in coconut coir with FDR sensors, an efficient water content measurment to control irrigations can be achieved by installing sensors closer to an irrigation point and upper side of substrates with noise filters.

Purpose: The Molybdenum which is the raw material of $^{99}Mo-^{99m}Tc$ generator is produced from the nuclear reactor. However, output has dwindled as the two nuclear reactors supplying the bulk of radioactive material-one in Chalk River, Ontario and the other in Petten, the Netherlands-have been closed for repairs or maintenance. This resulted in the enhancement of its price. So $^{99}Mo-^{99m}Tc$ generator using$(n,{\gamma})^{99}Mo$ is developed by Korea Atomic Energy Research Institute (KAERI). Medicinal availability of this generator is evaluated in this study. Materials and Methods: The radioactivity of $^{99m}Tc$ eluted in generator 1, 2 and 3 unit developed by KAERI was measured. The quality control test of generator such as appearance test, pH test, LAL test, sterility test, chemical impurity (Al) test and radiochemical purity test were performed. Planar and SPECT/CT image sof SD rat (6 weeks, Female) at 2 hr after injection of $^{99m}Tc-HDP$ (hydroxymethylenediphosphonate) (TechneScan HDP, Malinckrodt Medical, Dutch) and $^{99m}Tc-DPD$ (diphosphono-1, 2-propanedicarboxylicacid) (TECEOS, CIS bio international, France) which were labeled with $^{99m}Tc$ eluted in KAERI and commercial generator (40.5 GBq, Malinckrodt Medical, Dutch) using SPECT/CT camera (Symbia, Siemense, Germany) were obtained respectively. Results: The mean radioactivity of $^{99m}Tc$ elution generator 1unit was 4.18 GBq (113 mCi), generator 2 unit was 4.73 GBq (128 mCi) and generator 3 unit was 3.33 GBq (90 mCi). All quality control tests were within normal limit except pyrogentest. Pyrogen test was positive. Planar and SPECT/CT images of rat injected $^{99m}Tc-HDP$ which was labeled with $^{99m}Tc$ eluted in commercial generator show increased uptake in bone, stomach and bowl. Planar images show increased uptake in liver and bone in case of $^{99m}Tc-DPD$. However, images of rat injected $^{99m}Tc-HDP$ and $^{99m}Tc-DPD$ which were labelled $^{99m}Tc$ eluted in KAERI generator show increased uptake in bone, liver and spleen. Conclusion: If shortcoming is removed such as pyrogen and liver appearance, domestic role as an alternative generator is thought to be able to fill and to secure the national medical service by supplying $^{99m}Tc$ when the supply of $^{99m}Tc$ be comes short.

The purpose of this study was to examine the reality of inservice education provided to members of Korean Dental Hygienists Association, the state of relevant academic conferences, and the perception of the members about inservice education and academic conference. It's basically meant to help boost their participation in inservice education and their satisfaction with it, and to show some of the right directions for that. The subjects in this study were dental hygienists who attended a symposium on July 1, 2006. After a survey was conducted, the answer sheets from 489 participants were analyzed, and the findings of the study were as follows: 1. General hospitals and university hospitals made up the largest group(91.4%) that gave a monthly leave of absence, and the second largest group was dental hospitals(75.4%), followed by dental clinics(58.3%) and public dental clinics(48.0%). The most common closing time in dental clinics and dental hospitals was 5 p.m., and that was 12 p.m. in general hospitals and university hospitals. The dental hygienists in public dental clinics didn't work on Saturdays. By type of workplace, treatment was the most common duty for the dental hygienists in dental clinics and dental hospitals to perform, and those who worked at general hospitals, university hospitals and public health clinics were in charge of extensive range of jobs. 2. The rates of the dental hygienists who took that education stood at 94.9% in public dental clinics, 78.7% in dental hospitals and 75.3% in dental clinics, general hospitals and university hospitals. Regarding how many marks they got on an yearly basis, those who got eight marks or more made up the largest group(55.6%), followed by four marks or more(11.8%), six marks or more(3.4%), and two marks or more(1.5%). As for the usefulness of inservice education for their job performance, the largest number of the dental hygienists(40.8%) found it to be helpful, and the second greatest group(37.5%) considered its effectiveness to be so-so. The third largest group(8.4%) found it to be of great use, and the fourth biggest group(4.2%) considered it to be of no service. The fifth biggest group(l.3%) thought it was absolutely useless. By type of workplace, the workers in dental clinics, dental hospitals, general hospitals and university hospitals wanted the most to learn how to take care of clinical work(acquisition of up-to-date technology), and those in public health clinics hoped the most to learn about public dental health. By type of workplace, the workers in dental clinics had their sight set on self-development the most, and the dental hygienists in dental hospitals, general hospitals, university hospitals and public health clinics were most in pursuit of acquiring new knowledge. By type of workplace, the specific given conditions at work were most singled out by the dental clinic workers as the reason, and the dental hospital employees pointed out time constraints the most. The dental hygienists in general hospitals and university hospitals cited time constraints and financial burden the most, and the public health clinic personnels mentioned inaccessibility of a place for inservice education as the reason. 3. The public health clinic workers participated in academic conferences the most(90.8%), followed by the general and university hospital personnels(68.8%), dental hospital employees(65.6%) and dental clinic workers(65.5%). By type of workplace, the public health clinic workers(73.5%) expressed the most satisfaction, followed by the general and university hospital employees(67.7%), dental clinic workers(62.3%) and dental hospital personnels(54.1%). By type of workplace, the employees of dental clinics, dental hospitals, general hospitals and university hospitals preferred Saturdays, and the public health clinic workers had a liking for weekdays. As for a favored place, hotels were most preferred, followed by university hospitals, general hospitals, college lecture rooms, district halls and local public institutions. Hotels were most favored regardless of the type of workplace. 4. Regarding outlook on inservice education, they had the highest opinion on the facilities and given conditions of lecture rooms($3.41{\pm}0.83$), followed by the professionalism of lecturers($3.34{\pm}0.83$), procedures of receipt and attendance confirmation($3.34{\pm}0.83$) and class size($3.13{\pm}0.89$). On the contrary, they took the most dismal view of the inaccessibility of a place of inservice education($2.08{\pm}0.92$), followed by limited opportunity and limited date for that education($2.51{\pm}0.99$), extra financial burden($2.53{\pm}1.18$) and high tuition fee($2.57{\pm}0.96$).

Purpose : The system to refer terminally ill patients to palliative or hospice care which ultimately give them emotional, psychological, and social support hasn't been fully developed and organized yet in Korea. The controversies concerning the current referral system are being analyzed to present the improvements. Methods : The questionnaires were asked to be filled out by family members of the 76 patients by phone interview, who were referred from the Seoul National University Hospital between April, 2001 to March, 2002. They were referred to the 35 palliative and hospice care-giving institutes and hospitals which were given questionnaires by mail. Results : Of the 76 patient's family members, 47 family members accepted to answer the questionnaire. The first thing that influence to family to determine the referral of patient was solicitation of doctors or nurses (44%). And they were influenced by allowance for the other things such as convenience of patients (32%), convenience of caring family members (24%). In the course of determining of referred institutes, responders had considered at first their dwelling area, and then fame of institutes, the place which patent had wanted to spend last hours or which is suitable for patient's funeral service, and their financial condition. Thirty-eight the 47 responders answered that they had experienced difficulties in referral procedure. The worst among difficulties was unwanted discharge, and followings were lack of information about the referred institutes, concern about patient's suffering, resistance of patient and opposition of other family members, etc. Although they expressed dissatisfaction in referral procedure, most of them answered they had been satisfied with hospice care at referred institute after referral. Merits of referral which responders counted were patient's peace, caring family's comfort and reduced cost in order. Of the 35 referred institutes, 24 institutes' staffs responded mail questionnaires and sent to us in return. Except one responder, the rest approved the referral system and thought that referred patients had been satisfied with their hospice care. And they claimed that systemic support of the government is definitely necessary. The most difficult thing which responders experienced in care of referred patients was lack of information about patients. Besides, there were patient's financial problems, lack of understanding about their institutes of patients or family, and inconvenience of terminal cancer patient's pain control. Conclusion : The development and support of the organized referral system is needed to alleviate the troubles which patients, family members, and palliative or hospice institutes and hospitals have to face through the procedure of the referral.

Purpose: This study was a part of a drive to develop a community health center-based hospice management model which is concerned with hospice care at a community health care setting and available resources of the local community. Methods: Development of a community health center-based hospice management model involved evaluation of existing hospice-related research, including literature review, and research on hospice facilities at the study site, as well as evaluation of model operation. The latter involved community health center-based hospice test operation, and evaluation of test operation by a research team, including of a nursing professor majoring in hospice care and staffs from a community health center in Busan metropolitan city, regional cancer center, and regional terminal cancer patient medical institute. The study was conducted in the 2008 calendar year. Results: The community health center-based hospice management model provides service linked with local community resources, focusing on the local community health center. Financial and administrative assistance is provided by the regional cancer center, with collaboration from academic health care professionals who guide the operation management. The community health center hospice nurse in consultation with a visiting nurse team registers terminally-ill cancer patients and, after assessment, the hospice team prioritize hospice care during team meeting. Care is delivered by staffs and volunteers. Conclusion: The developed community health center-based hospice operation management model maximally utilizes available community health resources to produce qualitative improvement of regional health and welfare policy through improving the lives of home-based cancer patients and their family who are in medical blind spot.

The transmissible spongiform encephalopathies (TSEs) disease group are fatal neurodegenerative disorders affecting a wide range of hosts. The group includes kuru and Creutzfeldt-Jakob disease (CJD) in humans, scrapie in sheep and goats and Bovine spongiform encephalopathy (BSE) in cattle. The exact nature of the infectious agent involved in the transmission of these diseases remains controversial. However, a central event in their pathogenesis is the accumulation in infected tissues of an abnormal form of a host-encoded protein, the prion protein (PrP). Whereas the normal cellular protein is fully sensitive to protease ($PrP^{sen}$), the disease-associated prion protein ($PrP^d$) is only partly degraded ($PrP^{res}$), its amino-terminal end being removed. BSE was first reported in the mid-80s in the UK. Ten years later, a new form of human prion disease, variant CJD (vCJD) developed in the wake of the BSE epidemic, and there is now strong scientific evidence that vCJD was initiated by the exposure of humans to BSE-infected tissues, thus indicating a zoonotic disease. However, the ban on the feeding of animal-derived proteins to ruminants, and the apparent lack of vertical transmission of BSE, have led to a decline in the incidence of the disease within cattle herd and therefore, an assumed decreased risk for human contacting vCJD. The origin of the original case(s) of BSE still remains an enigma even though three hypotheses have been raised. Hypotheses are i) sheep- or goat-derived scrapie-infected tissues included in meat and bone meal fed to cattle, ii) a previously undetected sporadic or genetic bovine TSE contaminating cattle feed or iii) originating from a human TSE through animal feed contaminated with human remains. A host cellular membrane protein ($PrP^C$), which is abundant in central nervous system tissue, appear to be conformationally altered in the diseased host into a prion protein ($PrP^{Sc}$). This $PrP^{Sc}$ is detergent insoluble and partially protease-resistant ($PrP^{res}$). The term $PrP^{res}$ is normally used to describe the protein detected after protease treatment, in techniques such as Western immunoblotting, and enzyme-linked immunosorbant assay using fresh/frozen tissue. Immunohistochemistry may performed with formalin-fixed tissues. Also, clinical signs of the BSE are one of the major diagnostic indicators. Recently, atypical forms (known as H- and L-type) of BSE have appeared in several European countries, Japan, Canada and the United States. An unusual case was also reported in a miniature zebu. The atypical BSE fall into two groups based on the relative molecular mass (Mm) of the unglycosylated $PrP^{res}$ band relative to that of classical BSE, one of the higher Mm (H-type) and the other lower (L-type). Both types have been detected worldwide as rare cases in older animals, at a low prevalence consistent with the possibility of sporadic forms of prion diseases in cattle. This raises the unwelcome possibility that vCJD could increase in the human population. Now, active surveillance program against BSE is going on in Korea. In regional veterinary service lab, ELISA is applied to screen the BSE in slaughter and confirmatory tests by Western immunoblotting and immunohistochemisty are carried out if there are positive or suspect in the screening test. Also, the ruminant feed ban is rigorously enforced. Removal of specified risk materials such as brain and spinal cord from cattle is mandatory process at slaughter to prevent the infected material from entering the human food chain.

Jeju Special Self-Government Province adopted an autonomous police system for the first time since 60 years in Korean police. The purpose of autonomous police system is to offer a police service to be suitable in regional conditions. But Jeju autonomous police system for nearly one year after adoption is criticized to be established on the ground of political reason but not local decentralization. Actually Jeju autonomous police has not a clear cut jurisdiction and operation scope because of the jurisdiction duplication between national and autonomous police. The original task is confined on environment and sightseeing so on given to administration police for local self-government. So criminal investigation authority on general crimes is not to Jeuju autonomous police on account of special judicial police. First, it is the structural rationalization of Jeju autonomous police system. It speaks that Jeju provincial police bureau and police station have to be as national police institution, on the other hand, patrol district station and police box have to be as autonomous police institution. Of course, functional division has to be followed. National police performs managing all the assembly and demonstration by the management law on assembly and demonstration including the suppression against any large scale demonstration and disturbance, also the investigation on serious crimes just as international crimes and broaden area crimes including all the felony. Together national police performs the duty concerned to all the foreign affairs and national securities in along with the investigation on traffic accidents. On the other hand, autonomous police performs the function for citizen's life safety as crime prevention and the enforcement on the violation against police operation law, together the traffic management and the regulation on traffic violations. and the investigation on minor crime as simple violence or petty larceny including the management on local big events. Second, the budgetary of autonomous police is rationalized by the share of budgeting between Korean government and Jeju special self-government province. Third, urgent arrest authority on general crime and the rights of claims for the summary trial on minor crimes are given to autonomous police. Of course, this problem is resolved naturally in case of giving the investigation rights to autonomous police on minor crimes.
