The purpose of this study was to examine the correlation of oral health behavior, oral health state and PHP in an effort to facilitate the promotion of oral health and improve oral health care. The subjects in this study were patients who got a scaling at the oral hygiene practice lab in the department of dental hygiene in S college dental clinic from September 5 to December 1, 2007. The collected data were analyzed with SPSS WIN 12.0 program. The findings of the study were as follows: 1. The younger patients had a smaller number of FT index, and the older patients excelled the younger ones in oral health behavior involving the use of oral hygiene supplies, regular visit to dental clinics and dietary control. 2. The patients got 2.62 out of possible five points on oral health behavior, which indicated that their oral health behavior wasn't good enough. Those whose oral health behavior was better had a smaller number of DT index and a larger number of FT index. A better oral health behavior led to a lower PHP index. 3. There was a negative(-) interrelationship between oral health behavior and DT index, and oral health behavior had a positive(+) correlation with FT index. The oral health behavior had a negative(-) correlation to PHP index, which showed that a better oral health behavior led to a lower PHP index. The above-mentioned findings seem to suggest that oral health behavior is one of integral factors to affect oral health status and PHP index, and the kind of oral health education that could change oral health care attitude should be provided during scaling practice after grasping the actual oral health behavior of patients.

The purpose of this study was to examine the business awareness of dental coordinators and preferred working condition according to educational period, to suggest what improvements should be made. A survey was conducted for a year and four months from March 2007 to June 2008, and the collected data were analyzed, which made use of ${\chi}^2$(Chi-square) test, t-test. The findings of the study were as follows: 1. In regard to preferred conditions of employment, a dental hospital (42.0%) was most preferred by the incumbent dental hygienists investigated, followed by a dental clinic(29.4%). The largest number of the students who took dental coordinator courses had a liking for a dental hospital(41.9%), followed by university hospital and general hospital(29.0%)(p<0.001). 2. As for perception of dental coordinator, all the dental hygienists were aware of that occupation, and most of the students(81.9%) were cognizant of it(p<0.001). Concerning the necessity of that occupation, the students who felt the need for that(94.8%) outnumbered the dental hygienists who did(85.2%)(p<0.05). 65.9 percent of the dental hygienists and 84.5 percent of the students looked upon a dental hygienist as the best occupation that also could serve as a dental coordinator(p<0.01). 3. Concerning a favorite type of work including an official title, the dental hygienists wanted to work as the chief of counseling section the most(34.1%), and the largest group of the students hoped to become a section chief or team leader(35.2%). In regard to the most integral field of work, the dental coordinators(51.1%) and students(65.8%) attached the most importance to counseling(p<0.05). 4. The dental hygienists were better gratified than the students in every regard(p<0.001). The former($4.00{\pm}0.41$) looked at that occupation in a better way than the students($3.81{\pm}0.50$) as well(p<0.01). The abovementioned findings suggested that it would be advisable to provide dental hygienists with a certain level of a clinical career with education in order to ensure the success of dental coordinator education.

The home nursing care system is an integral part of the health care delivery system in order to meet the various needs of consummer, in particular, early discharge patient from the hospital, patient with long term care needed and the elderly. To find out the cost of home nursing care services, the home nursing care records of patients registered by home nursing care units established in public hospital with 150beds during the period of 1996 - 1997 were analyzed. The subjects were 102patients, 45 of male patients and 57 of female patients, those who live in a rural area in Kymiggi - Do The results obtained are as follows : 1. The male patients accounted for 44.1% of the total, with 45cases : group aged 60 years and more was the largest group, accounting for 79.5%. 2. The most frequent disease revealed was the osteoporosis which constitute 35.3% of the total registered patients, followed, in order, by malignant tumor, cerebrovascular disease. 3. It revealed that the cost per visit for the male was 47,764won ; the female, 46,078 won per visit. Noteworthy the cost per visit was high in the older patient. It was clearly that the gender, years of age and the cost per visit were statistically significant at 0.01 level and 0.05 level. 4. The cost per visit for the non complicated disease was slightly higher than the complicated disease, but it is not statistically significant, the cost per visit by type of disease varied, the cost per visit for COPD was the highest, followed, in order, by in malignant tumor, cancer, diabetes, osteoporosis etc. 5. It revealed that home nursing care cost for a eligible disease for home nursing care was less than the cost for hospitalization of the same disease, therefore, we expect that the home nursing care is cost efficiency. In conclusion, the home nursing care costs are needed to analyze further in comparison with the hospitalization costs for a certain disease.

Purpose : Fluorescence in situ hybridization (FISH) on uncultured amniotic fluid cells offers the opportunity for rapid screening of aneuploidies and has become an integral part of the current practice in many clinical cytogenetics laboratories. Here, we retrospectively analyzed the results of interphase FISH in 943 amniotic fluid samples and assessed the efficiency of FISH for rapid detection of aneuploidies. Methods : Interphase FISH for chromosome 13, 18, and 21 was performed in 943 consecutive amniotic fluid samples for rapid diagnosis of aneuploidies referred from 2004 to 2006. Karyotypes from standard cytogenetic analysis were compared to the FISH results. Results : A total of 45 chromosomal rearrangements (4.8%) were found after conventional cytogenetic analysis of the 943 amniotic fluid. After exclusion of known familiar chromosomal rearrangements and inversions (2.1%, 20/943), 2.7% (25/943) were found to have chromosomal abnormalities. Of this group, 0.7% (6/943) were chromosomal abnormalities not detectable by FISH and 2.0% (19/943) were numerical abnormalities detectable by FISH. All 14 cases of Down syndrome (Classic type, 13 cases; Robertsonian type, 1 case) and 5 cases of trisomy 18 were diagnosed and detected by FISH and there were no false-positive or -negative results (specificity and sensitivity=100%). Conclusion : The present study demonstrates that FISH can provide a rapid and sensitive clinical method for prenatal identification of chromosome aneuploidies. However, careful genetic counseling is essential to explain the limitations of FISH, including the inability to detect all chromosomal abnormalities and the possibilities of uninformative or false-negative results in some cases.

Tidal flats have been regarded to carry out transformation and removal of land-derived organic matter, and this purifying capability of organic matter by tidal flats is one of very important reasons for their conservation. However, integral biogeochemical studies on production and decomposition of organic matter by benthic microbes in tidal flats have been absent in Korea, although the information is indispensable to quantification of the purifying capability. Our major goals in this multidisciplinary research were to understand major biogeochemical processes and rates mediated by diverse groups of microbes dominating material cycles in the tidal flats, and to assess the contribution of benthic microbes to removal of organic matter and nutrients in the tidal flats. Our study sites were Ganghwa and Incheon north-port tidal flats that had been regarded as naturally well reserved and organically polluted, respectively. Our research group measured over 3 years primary production, biomass and community structure of primary producers, abundance and production of bacteria, enzyme activities, distribution of protozoa and protozoan grazing rates, rates of denitrification and sulfate reduction, early sediment diagenesis, primary production and respiration based on oxygen microelectrode. We analyzed major features of each biogeochemical process and their interactions. The results are compiled in the following articles in this special issue: An (2005), Hwang and Cho (2005), Mok et at. (2005), Na and Lee (2005), Yang et at. (2005), and Yoo and Choi (2005).

The ultimate goal of this research is to develop a botanical biofiltration system that combines a green interior, biofiltering, and automatic irrigation to purify indoor air pollutants according to indoor space and the size of biofilter. This study was performed to compare the stability of air flow characteristics and removal efficiency (RE) of fine dust within a wall-typed (vertical) botanical biofilter depending on humidifying cycle and to investigate RE of volatile organic compounds (VOCs) by the biofilter. The biofilter used in this experiment was designed as an integral form of water metering pump, water tank, blower, humidifier, and multi-level planting space in order to be suitable for indoor space utilization. As a result, relative humidity, air temperature, and soil moisture content (SMC) within the biofilter showed stable values regardless of three different humidifying cycles operated by the metering pump. In particular, SMCs were consistently maintained in the range of 27.1-29.7% during all humidifying cycles; moreover, a humidifying cycle of operating for 15 min and pausing for 45 min showed the best horizontal linear regression (y = 0.0008x + 29.09) on SMC ($29.0{\pm}0.2%$) during 120 hour. REs for number of fine dust (PM10) and ultra-fine dust (PM2.5) particles passed through the biofilter were in the range of 82.7-89.7% and 65.4-73.0%, respectively. RE for weight of PM10 passed through the biofilter was in the range of 58.1-78.9%, depending on humidifying cycle. REs of xylene, ethyl benzene, total VOCs (TVOCs), and toluene passed through the biofilter were in the range of 71.3-75.5%, while REs of benzene and formaldehyde (HCHO) passed through the biofilter were 39.7% and 44.9%, respectively. Hence, it was confirmed that the wall-typed botanical biofilter suitable for indoor plants was very effective for indoor air purification.

In the Soviet Union School health services are provided as an integral part of the health care delivery system, which is under the Ministry of Health. This paper presents an overview of the Soviet Union's health care delivery system, the model for the delivery of school health service, the role and training of school personnel involved in school health services and implications the Soviet model may have for the countries. 1. School health services are a part overall Soviet health system under the Ministry of Health. 2. Municipal and rural health departments implement programs at the local level. Diagnosis and treatment are conducted through "polyclinics" that are outreach divisions of a district hospital. 3. Education institutions for the development of health manpower, including medical schools and nursing schools, are under the Ministry of Health, as are medical and scientific search institutes.

In the past twenty years, there has been a rapid increase in the volume of traffic in Korea due to the Korean great growth of the Korean economy. Since transformation provides an infrastructure vital to economic growth, it becomes more and more an integral part of the Korea economy. The importance of coastal shipping stands out in particular, not only because of the expansion limit on the road network, but also because of saturation in the capacity of rail transportation. In spite of this increase and its importance, coastal shipping is falling behind partly because it is givenless emphasis than ocean-going shipping and other inland transportation systems and partly because of overcompetition due to excessive ship tonnage. Therefore, estimating and planning optimum ship tonnage is the first take to develop Korean coastal shipping. This paper aims to estimate the optimum coastal ship tonnage by computer simulation and finally to draw up plans for the ship tonnage balance according to supply and demand. The estimation of the optimum ship tonnage is peformed by the method of Origin -Destimation and time series analysis. The result are as follows : (1) The optimum ship tonnage in 1987 was 358, 680 DWT, which is 54% of the current ship tonnage (481 ships, 662, 664DWT) that is equal to the optimum ship tonnage in 1998. this overcapacity result is in excessive competition and financial difficulties in Korea coastal shipping. (2) The excessive ship tonnage can be broken down into ship types as follows : oil carrier 250, 926 DWT(350%), cement carrier 9, 977 DWT(119%), iron material/machinery carrier 25, 665 DWT(117%), general cargo carrier 17, 416DWT(112%). (3) the current total ship crew of 5, 079 is more than the verified optimally efficient figure of 3, 808 by 1271. (4) From the viewpoint of management strategy, it is necessary that excessive ship tonnage be reduced and uneconomic outdated vessels be broken up. And its found that the diversion into economically efficient fleets is urgently required in order to meet increasing annual rate in the amounts of cargo(23, 877DWT). (5) The plans for the ship tonnage balance according to supply and demand are as follows 1) The establishment of a legislative system for the arrangement of ship tonnage. This would involve; (a) The announcement of an optimum tonnage which guides the licensing of cargo vessels and ship tonnage supply. (b) The establishment of an organization that substantially arrangement tonnage in Korea coastal shipping. 2) The announcement of an optimum ship tonnage both per year and short-term that guides current tonnage supply plans. 3) The settlement of elastic tariffs resulting in the protect6ion of coastal shipping's share from other tonnage supply plans. 4) The settlement of elastic tariffs resulting in the protection of coastal shipping's share from other transportation systems. 4) Restriction of ocean-going vessels from participating in coastal shipping routes. 5) Business rationalization of coastal shipping company which reduces uneconomic outdated vessels and boosts the national economy. If we are to achieve these ends, the followings are prerequisites; I) Because many non-licensed vessels are actually operating and threatening the safe voyage of the others in Korea coastal routes, it is necessary that those ind of vessels be controlled and punished by the authorities. II) The supply of ship tonnage in Korean coastal routes should be predently monitored because most of the coastal vessels are to small to be diverted into ocean-going routes in case of excessive supply. III) Every ship type which is engaged in coastal shipping should be specialized according to the characteristics of its routes as soon possible.

It is very important to make shorter and healthier pot plants with increased numbers of branch at a growing stage before short-day exposure. Especially light and nutrient conditions directly affect the growth and quality of the plants as described above. In this study, the effects of nutrient strength and light intensity on the nutrient uptake and growth of young Kalanchoe plants (Kalanchoe blossfeldiana 'Marlene') during this growth stage were investigated. The plants were grown under two radiation integral (15.8 and 7.9 $mol{\cdot}m^{-2}{\cdot}d^{-1}$, PPF) and three EC (0.8, 1.6 and 2.4 $dS{\cdot}m^{-1}$) conditions. Leaf area, fresh weight, dry weight and number of branch were higher at a higher PPF, and this tendency was more evident at an EC above 1.6$dS{\cdot}m^{-1}$. The plants became higher at a lower PPF. When the EC was at 0.8 $dS{\cdot}m^{-1}$, the plants did not grow so healthy regardless of PPF conditions. EC decrement in the nutrient solution was increased with increase of nutrient strength. With growth stage, the nutrient uptake was increased with increases of nutrient strength and PPF. At a higher PPF, $NO_3-N,\;K^{+}\;and\;Ca^{2+}$ were much more absorbed, and especially the uptake of $K^{+}$ was 1.1 to 1.5 times greater than that or $NO_3-N$. From the results, the EC needed above 1.6 $dS{\cdot}m^{-1}$ during the seedling stage in order to make more healthy Kalanchoe plants having more leaf area, fresh weight, dry weight and number of branches under adequate light conditions.

The burden of addressing the damage and financial losses caused by disaster events falls primarily on local governments. Given this reality, preparing for disasters and assessing the effects of disaster management would be more effective if both were carried out at the local level. However, disaster management in South Korea is realized at the national level, revolving around the central government. The Ministry of Public Safety and Security, which was newly established after the sinking of MV Sewol, was criticized for failing to carrying out its role as a "disaster control tower" in dealing with the earthquakes near the city of Gyeongju in 2016. The criticism, as well as deep anxiety concerning the ministry's ability to effectively respond to disasters, means that there is a need for a practical alternative plan to the current method of dealing with disasters. As such, there is an increasing call to re-examine the role of the police force, which played an integral part in past disaster response efforts, in future disaster events. Among the various activities the police force performs, this study focused on one particular role and function of the police, namely community policing. Specifically, this study examined community policing within the context of local governments. The primary purpose of community policing is crime prevention. But the police must respond to citizens' expectations and desires that the police expand the scope of its role. Thus, to maximize public safety and order, the police must be actively engaged in conducting disaster response activities. Hence, this study concentrated on the measures, including community policing, that need to be taken to enable the police to respond rapidly and effectively to disaster events, thereby minimizing losses, and to contribute meaningfully to disaster recovery efforts. Because community policing requires public cooperation, community-oriented disaster response and disaster management are closely examined. This study basically seeks to expand the scope of community policing to strengthen disaster safety. Furthermore, this study aims to assert that disaster safety can be promoted by establishing a cooperation system between the police and private security; changing how the role of community policing in disaster response activities is perceived; increasing professional manpower and establishing a comprehensive and independent department dedicated to disaster-related matters; and merging consultative organizations into one organization. Additionally, this study states that an integrated CCTV platform and police cars on disaster prevention patrol duties would enhance the capability of the police to respond to disasters and perform their community policing activities.
