Purpose: The purpose of this study is to investigate the current state of the home-based cancer patient management project of public health centers throughout the country. The results of the investigation is employed to identify obstacles to the execution of the program and, finally, to develop an efficient management program of home-based cancer patients. Methods: Data on the home-based cancer patient management project were collected and analyzed through visiting interviews or telephone interviews with 225 public health centers throughout the country for six months from July to December, 2006. Results: Obstacles to the present execution of the home-based cancer patient management project were identified. Some of them are : (1) patients' low trust in cancer patient management by local health centers, (2) absence of programs customized to local communities, (3) lack of personnel and vehicles for home-based cancer patient management, (4) lack of education program for personnel in charge of home-based cancer patient management, (5) problems in public health doctors, weak connection to private medical institutions, (6) absence of medical institutions and hospice facilities for cancer patients, and (7) non-standardized volunteer workers, so on. Considering all these problems, some effective management methods are proposed. The basic concept is to keep the autonomy and variety of the local helath centers. And based on this concept, three models of (1) public health center controlled model, (2) medical institutions and hospice facilities-entrusted model and (3) medical institutions and hospice facilities-cooperative model are developed. Conclusion: By adopting an adequate model among proposed three models, the public health centers are expected to achieve an efficient utilization of material resources and manpower. In addition, by inventing their own programs that are proper for the local societies, they can improve the home-based cancer patient management.

Twelve bottom sediments and three cores were collected in Juam reservoir for a study on transportation, which was controlled by particle grain size (2mm-200{\mu}m,\;200-100{\mu}m,\;100-50{\mu}m,\;50-20{\mu}m,\;<20{\mu}m), and vertical distribution of heavy metals. Sediment cores were sliced into 2 to 5 cm intervals to measure heavy metal concentrations in interstitial water and sediments with depth. Pb isotopic compositions of core samples were determined to calculate sedimentation rate. Regardless of sampling sites, levels of heavy metals and trace elements in bottom sediments are nearly constant with mean values of $14.9\;{\mu}g/g\;for\;As,\;0.81{\mu}g/g\;for\;Cd,\;30.7{\mu}g/g\;for\;Cu,\;34.7{\mu}g/g\;for\;Ni,\;63.3{\mu}g/g\;for\;Pb\;and\;87.9{\mu}g/g\;for\;Zn$. In general, Cu, Pb, Zn, Wi, and Cr in fraction of $<20{\mu}m$ exhibit the highest concentration, but content of As is the highest in grain size of $2\;mm-200\;{\mu}m$ and $200-100\;{\mu}m$. Fe and Mn occur as the dissolved compositions of the highest concentrations in interstitial waters and increase in their concentrations toward lower part of cores. On the contrary, concentrations of Zn and Cu show the highest value in the uppermost part in cores, suggesting these elements are released from reductive dissolution of hydroxides and oxidation of organic matters under different redox conditions. The highest accumulations of Cu, Ni, Pb, and Zn contents in the sediment cores are observed at 0-4 cm layers, and concentrations of Cu and Pb are especially high, implying these heavy metals are originated from anthropogenic sources. The apparent sedimentation rate estimated using unsupported $^{210}Pb$ is 0.91 cm $year^{-1}$, corresponding about 10 cm sedimentation in total depth since construction of Juam dam. These results will provide available information for management of bottom sediment in Juam reservoir.

The Ecosystem and Nature Map (ENM) is basic map for current status of natural resources. The map has been offered information to ecological conservation and restoration, as well as to land use planning and policy making. The map composed of 794 sheets in 1:25,000 scale classifies total areas into three grade zones (1st, 2nd and 3rd grade zones) and separately managed zone. In 2005, the first draft Ecosystem and Nature Map was prepared by the second National Ecosystem Survey. It was opened for the people to search and appeal. So 1,419 cases of public appeals on the first draft Ecosystem and Nature Map were submitted in 2005. After partial revision, the first Ecosystem and Nature Map was announced in 2007. The second draft Ecosystem and Nature Map was prepared by the third National Ecosystem Survey and opened to public in 2012. As a result, 1,263 cases of public appeals were submitted in 2012. Since the first announcement of the Ecosystem and Nature Map in April 2007, 182 cases of public appeals on the Map were submitted until December 2013. Among them, 159 cases were announced with revision. According to the first Ecosystem and Nature Map announced in 2007, graded areas covered 7.5% in the 1st grade zone, 39.2% in the 2nd grade zone and 44.7% in the 3rd grade zone of the national land area, respectively. In the second draft Ecosystem and Nature Map in 2012, areas of the 1st grade zone and the 2nd grade zone were 9.2% increased 1.7 percentage points and 45.5% increased 6.3 percentage points, and areas of the 3rd grade zone were 36.6% decreased 8.1 percentage points. Among areas of the 1st grade zone, Gangwondo occupies 54.3% in 2007 and 47.6% in 2012. Gangwondo consists of the highest percentage of the 1st grade zone and the smallest of the 3rd grade zone. Seoul has the highest percentage of the 3rd grade zone. There were the highest increase of the 1st grade zone in Gyeongsangbukdo and the highest decrease in Jeollabukdo and Seoul. Vegetation is the most important evaluation factor to determine the grade of the Ecosystem and Nature Map.

For more efficient and proactive safety control of imported food, new trend in U.S. is emerging, which assesses the food safety control systems of exporting countries using Systems Recognition Assessment Tool and helps ensure safety of imported foods. This study examines trends in development and application of assessmemnt tool and country assessment reports in U.S. where an active discussion on this issue is in progress. The expert interviews were also conducted. U.S. Systems Recognition Assessment Tool was developed by FDA to recognize the potential value in leveraging the expertise of foreign food safety systems and help ensure safety of imported food. The tool is comprised of ten standards and provides an objective framework for determining the robustness of trading partners' overall food safety systems. Using its own tool, the U.S. FDA conducted a preliminary assessment of the food safety control systems of New Zealand and Canada. According to the U.S.-New Zealand and the U.S.-Canada assessment reports, the overall structure of the systems was similar between the countries. In summarizing the opinions of experts, such a trend in National Food Safety Control System Assessment may be utilized in the sanitary assessment and the control of imported food border inspection frequency before importing food. It would contribute to more effective distribution of national budget and increased public trust. Additionally, international collaboration as well as securing of qualified experts and sufficient budget appear to be crucial to further increase the utility of National Food Safety Control Systems Assessment. In conclusion, firstly, it is critically important for the competent authority of South Korea to proactively respond to international trend in National Food Safety Control System Assessment by identifying the details of its background, assessment purpose, core assessment elements, and assessment procedures. Secondly, it is necessary to identify and complement the weaknesses of Korea's food safety control system by reviewing it with U.S. Systems Recognition Assessment Tool. Thirdly, by adapting the assessment results from imported countries' food safety control systems to the imported food inspection intensity, the resources previously used in inspecting the imported food from accredited countries can be redistributed to inspecting the imported food from unaccredited countries, and it would contribute to more efficient imported food safety control. Fourthly, the competent authority of South Korea should also consider developing its own assessment tool designed to reflect the unique characteristics of its food safety control system and international guidelines.

It has been 10 years since the facility modernization projects of traditional markets was rigorously undertaken. Although more than 835 traditional Korean markets nationwide have already completed these projects, there does not exist a specific set of standards of installation, future maintenance, and management. As a result, the complaints made by civil stakeholders in accordance of the actual facility installation caused problems and delays of related projects. In addition, while some local governments secured and implemented their own differing standards, others have not yet established their own separate standards for maintenance and management. Specifically, 694 traditional markets nationwide were supported for the cost of installing arcades by 2010. For the short period of time after the arcade-supported projects were deployed, the number of the traditional markets had been rapidly growing as a prime example of the facility modernization projects. The arcade facilities are being planned and installed merely for screening the rain or the sun. Without fundamental data for the newly landscaped environments or information on the actual conditions of usage and assessment, there is a lack of comprehensive approaches that could possibly organize the public environments. Furthermore, the amount of support needed for repairs, maintenance, and management from the central and local governments is gradually increasing. Thus, it becomes both crucial and necessary to complement the current set of standards. The purpose of this study is to examine the actual conditions of usage, maintenance, and management among those traditional market facilities that were installed with the supports of the facility-modernization projects, especially for arcades. This will be carried out through investigating the local problems, issues, and considering international case studies. The results of this study will provide measures for effective and efficient installation and management of traditional market arcades. Improvements in the use of public resources could be directed towards transforming public business, as well as public enhancement and functional maintenance and reinforcement. Under this condition, the arcade is not a simple area to avoid rain or sunlight; it becomes a public space. It is highlighted that the arcade should establish its public business not only to activate markets but also to refine street environments and revitalize local communities. A more specific way to improve is introduced through systematic supplementation. This is needed to attract effective participation from local residents and is done so by conducting a fair procedure from the first stage of business and by providing guidelines for establishing arcades as public facilities. The study points out to the problem of merchants-centered plans and street use. It presents the need to expand to involve residents and customers. Given that the arcade is a public facility and merchants' ability to maintain it is limited, manuals and systems for its maintenance needs to be introduced through multi-party agreement of merchants, government, residents and customers.

To investigate effect of on sexual maturation in spotted seabass, Lateolabrax maculatus the sexual maturation, photoperiods were established to natural photoperiod, 9L:15D, 11L:13D, 13L:11D and 15L:9D. After rearing for 90 days from August 11 to November 10, gonadosomatic index (GSI) and hormones were analyzed. In the female, GSI was $1.07{\pm}0.09%$ in the natural photoperiod, $1.93{\pm}0.06%$ in 9L:15D, while the GSI of male was $0.75{\pm}0.05%$ in the natural photoperiod, $1.89{\pm}0.12%$ in 9L:15D and $0.22{\pm}0.05%$ in 15L:9D and the lowest in 15L:9D, respectively. The blood estradiol (E2) of female was $226.0{\pm}13.6pg/ml$ in the natural photoperiod, and the highest value of $296.3{\pm}15.0pg/ml$ in 9L:15D. The male $17{\alpha}20{\beta}OHP$ was similar to the female with $196.3{\pm}17.0pg/ml$ in the natural photo period and $133.0{\pm}15.5pg/ml$ in 9L:15D. The testosterone (T) of male was $259.3{\pm}33.1pg/ml$ in the natural photoperiod, but the hightest value of $370.5{\pm}27.5pg/ml$ in 9L:15D. These results provide basic information from sexual maturation of spotted seabass.

Heavy mineral provide an important information for sediment provenance as well as a potential submarine mineral resources. We compared the heavy mineral characteristics between Southeastern Yellow Sea Mud (SEYSM) and Southwestern Cheju Island Mud (SWCIM) surface sediments. We separated heavy minerals from 28 surface sediments in each mudbelt, and then carried out stereo-microscopic, field-emission scanning electron microscopic, energy dispersive spectroscopic and electron probe microanalysis to characterize the type, abundance, mineralogical properties and distribution pattern of heavy mineral. Amphibole and epidote, which are two major heavy minerals, account for more than 70% of total heavy minerals. Zircon and sphene contents are more abundant in SEYSM, whereas apatite and rutile contents are more abundant in SWCIM. Monazite only occurs in some area of SEYSM. Sphene and monazite content decrease to the south in SEYSM. Both garnet-zircon index (GZi) and rutile-zircon index (RuZi) are low in SEYSM but high in SWCIM. Amphiboles in SEYSM primarily correspond to hornblende, however those in SWCIM represent variable composition from pargasite, tshermakite, hornblende to tremolite. Garnets in SEYSM have high Mg and low Ca, but those in SWCIM have low Mg with variable Ca. Different heavy mineral characteristics between SEYSM and SWCIM suggests that sediments in each mudbelt have different provenances. Although this study implies that SEYSM sediment may mostly come from nearby Korean western rivers such as the Keum and Han rivers, this study does not suggest any idea of the source area of SWCIM sediment. Further study is needed to interpret the provenance and transportation mechanism of mudbelt sediments through the heavy mineral research for the river sediments flowing into the Yellow Sea and much more marine sediments.

Objectives: This study was conducted to suggest the way to improve the tobacco control program of public health centers in Korea. Methods: A survey with a self-administered questionnaire was conducted among 246 persons in charge of tobacco control work in public health centers nationwide in December, 2006. Frequency analysis was performed with a final sample of 212 respondents with SPSS 12.0 for Windows. Results: The duration of engagement in tobacco control work was less than 3 years among 86.7% of respondents, and 87.3% of respondents had other duties besides tobacco control. Almost all public health centers conducted a campaign with posters or leaflets, and smoking prevention education among adolescents. The actual priority for programs was based on the community diagnosis in only 33.5% of the cases. Only 1.9% of respondents complained lack of budget, on the other hand, 44.7% of respondents appealed insufficient number of personnel. The route of knowledge and skill was largely dependent on self-learning or information from colleague. Collaboration with other related department was done well in 39.5% of the cases. The majority of respondents was satisfied with the general support from central government. Conclusions: To improve the tobacco control program of public health centers, it is needed the reinforcement of capacity and specialty among personnel, priority setting and performance of programs based on the scientific evidence, induction of community participation, utilization of community human resources, development of education and training course for practical skill, effective networking among departments.

Resale price maintenance has long been employed in book distribution, perhaps longer than for any other product. Another unusual practice in the book trade that has proven to be quite durable in spite of its substantial cost in real resources is the returns policy. Publishers typically grant the right to return unsold books within a stipulated time for full credit against future orders. This paper investigates the functions and effects of resale price maintenance in the book trade, and argues that resale price maintenance and returns are substitute methods of providing the same economic function. Resale price maintenance can be used to compensate booksellers for initially stocking books with uncertain prospects and for providing a conduit through which manufacturers acquire information about consumer demand (market testing services). Permitting the return of unsold books for full credit places a floor under retail prices and transfers a considerable portion of the cost of introducing a new product line back to the publisher. Both reflect publishers' needs to have their books displayed. In the U.S. returns privileges were first proposed in 1913, roughly coincident with the Macy decision outlawing RPM. Publishers slowly granted return privileges, which become nearly universal by 1970. The decline in margins in recent years has been accompanied by an increase in returns as the return policy served to substitute for lost margins on successful titles as a methods of compensating full-line booksellers. In contrast, returns privileges are unusual in countries where price maintenance in books has been practiced. These observations are consistent with our analysis. In Korea, resale price maintenance of books is practiced under an exception to Korean antitrust law. The availability of effective price maintenance is likely to reduce the use of returns programs. Since consumers prefer to obtain books at outlets where they know the books are likely to be stocked rather than taking a chance on stores that carry a more limited line, it also provides a strong incentive for booksellers to expand. But the privilege of resale price maintenance should be confined to books which publishers want to be price maintained. Resale price maintenance and returns system differ in the transactions costs associated with inventory holding, and publishers' judgement on the comparative advantage of the two schemes should be honored. Publishers should also remain free to authorize sales at discount at any time not to impair the ability of booksellers to dispose of product variants that prove unpopular.

Benign prostatic hyperplasia (BPH) is a highly prevalent, age-related disorder in men which place a considerable burden on health care resources worldwide. While BPH and hypertension are apparently diverse disease processes, they have some features in common(e.g. underlying etiology of the sympathetic nervous system). The purpose of this study is to estimate the prevalence of lower urinary tract symptoms using I-PSS(international prostate symptom score) and to investigate the association of hypertension with I-PSS. This study was carried out to 390 men(40~86 year old) at 3 Myun in Chungju City from July to August, 1997. Subjects answered on questionnaire for I-PSS and were checked age, education, marital status, annual income, blood pressure. The mean age of subjects was 59.8 year old. The mean of I-PSS were increased by age decades(40~49, 50~59, 60~69, 70~86) and it's scores were 4.4, 7.0, 8.2, 12.3 respectively. Strong correlations were observed between the I-PSS and the QUL(quality of life)(P=0.0001). I-PSS(mean-value) were 7.85 in hypertensive group and 8.39 in normotensive group but there was no statistically significance between the two groups(P>0.05). The proportion of mean scoring greater than 8 was 42.5%. There have been reports of association between lower urinary tract symptoms and hypertension, but there was no consistent suggestion that such an association could be casual. The need for high-quality epidemiological information and consequent increased prospects for prevention is obvious.
