This research would be the first step toward in the long processes of proton technology industrial cluster development by focusing on the region's readiness and acceptability of the proton technology project. As is shown in our questionnaire survey, the top priorities needed to consider for the Proton Technology project are found to be job creation (mean 3.74), regional economic development (mean 3.72), industry infrastructure(3.54), institution for science and education(3.53), economic inequalities(3.33), tourism industry revitalization(3.20). For public servants top priorities in order found to be regional economic development, job creation, industry infrastructure, institution for science and education, economic inequalities, tourism industry revitalization. Universities' priorities in order found to be job creation, regional economic development, institution for science and education, industry infrastructure, economic inequalities, tourism industry revitalization. The mean reliability score for the each party was found to be mayor((3.04), citizens(2.99), province(2.97), private corporation(2.96), and universities((2.93). Of particular note, the mean score except the mayor were all below median (3.00). province(3.24), city council member(3.20), public employees (3.09), private corporation(3.03), nonprofit organization (2.97), mass media (2.96), citizens(2.96), and universities(2.89). The universities and colleges also should revise their strategic plans and thus restructure their internal academic programs, and must develop their own collaborative programs with Proton Engineering Frontier Project, related industries, city, and other government units. Not only educating, training, and providing top-notched man powers to the proton technology industries will be one of their primary missions.

We report a chronic cerebral paragonimiasis from a 41-year-old Korean man who complains a headache and weakness of left motor neuron components. Magnetic resonance images of the brain revealed conglomerates of multiple ring-like enhancements in tempore-occipital and frontal lobes of the right hemisphere. An intradermal test for paragonimiasis westermani was positive. The patient was born near an endemic area of paragonimiasis and used to eat boiled or grilled freshwater crayfish in his childhood. Nodules in the brain were resected through craniotomies. The eggs of P. westemani were identified pathologically and parasitologically in the calcified necrotic lesions. Examinations on sputum and fecal specimens for the eggs of P. westemani were shown to be negative and a chest radiograph was normal. It is presumed that the brain lesions were formed by P. westemani approximately 30 years ago.

This study aims to establish a landscape plan that can preserve the identity of the region while meeting the unique functions related to land use of the Saemangeum agricultural land. In addition, it was intended to prepare a mid- to long-term landscape plan basic concept for the formation and management of the Saemangeum agricultural land landscape. Therefore, in this study, landscape management by type for processing/storage facilities, production/processing facilities, complex/sales facilities, and research/experimental facilities for facilities scheduled to move in after setting the direction and five strategies for landscape management considering the specificity of agricultural land direction was set. In addition, the landscape management direction for 6 common landscape elements such as buildings, open spaces, advertisements, colors, public facilities, and night scenery was also presented. In particular, Agroworks, Agro City, and Agro Town, which are important landscape areas, are landscape-focused management areas, and the landscape management direction for the area has been established. This study is considered to have great utility value when setting landscape standards for public or private buildings and infrastructure, development projects, etc. to be moved in prior to establishing a landscape plan for agricultural land. It is expected that it can be used as a basis for deliberation and review of the landscape standards derived from this study in the future landscape-related licensing for agricultural land.

Background: Hepatitis B virus (HBV) infection is one of the worldwide public health problem affecting about 300 million people. The envelope protein of HBV consists of three components known as preS1, preS2, and S antigen. According to the recent study, anti-HBs Ab showed effective neutralization ability against HBV from chronic hepatitis B and liver transplant patients, suggesting the possible development of therapeutic antibody. Methods: Spleen cells immunized with S antigen of HBV were fused with myeloma cell line to obtain HBsAg specific monoclonal antibodies. High affinity antibodies against HBsAg (adr, ad and ay type) were selected by competitive ELISA method. Nucleotide sequence of the variable regions of monoclonal antibodies was analyzed by RT-PCR followed by conventional sequencing method. Results: We produced 14 murine monoclonal antibodies which recognize S antigen of HBV. Two of them, A9-11 and C6-9 showed the highest affinity. The sequence analysis of A9-11 revealed that variable regions of the heavy chain and light chains are members of mouse heavy chain I (B) and light chain lambda 1, respectively. Likewise, the sequence analysis of C6-9 revealed that variable regions of the heavy chain and light chains are members of mouse heavy chain II (B) and light chain kappa 1, respectively. Neutralization assay showed that A9-11 and C6-9 effectively neutralize the HBV infection. Conclusion: These results suggest that A9-11 and C6-9 mouse monoclonal antibodies can be used for the development of therapeutic antibody for HBV infection.

Safety of reclaimed wastewater irrigation needs to be evaluated to promote public health. Quantitative microbial and toxic risk assessment was conducted to identify the level of risk for farmland workers who use reclaimed wastewater and groundwater in Jeju island. Microbial risk through inhalation and ingestion exposure was below acceptable level (less than $10^{-3}$) of $7.07{\times}10^{-6}$ for reclaimed wastewater and $9.99{\times}10^{-8}$ for groundwater irrigation worker. Aggregate exposure risk of Ni, As and Cu was most contributable to overall risk in both reclaimed wastewater and groundwater irrigation plot. High cumulative exposure risk was estimated through non-dietary soil ingestion and dermal contact of soil, due to the high concentration of As, Cu and Ni in farmland soil. Overall toxic risk was $2.68{\times}10^{-4}$ for reclaimed water and $2.39{\times}10^{-4}$ for groundwater irrigation, which could not meet acceptable toxic risk level of $10^{-6}$. Further efforts, such as provide personal protective equipments or public health education, need to be implicated to reduce adverse health risk.

As a basic life-supporting infra in modem life, road should carry out various functions; transport, public linear network service, open activity space. Case study villages were divided into plan-based improved one(3 subtypes) and not one(4 subtypes). On total 21 case study villages($3{\times}7$ subtypes), questionnaire surveys were performed. Villagers' satisfaction level to road conditions in the plan-based improved villages showed much higher than not improved ones, which means that improvement of village roads be a vital subject in level-up of quality of rural life. Traffic function of village roads was responded as a principal one, while other various functions as between-villagers communication, car-parking and accommodation of public utilities were also required. In this viewpoint, village roads should be multi-purposedly developed in future. So, it was concluded that the road improvement strength would vary with geographical and topographical conditions of each village. Although villagers' unsatisfaction level on road service was very high, their demand level of and supporting will toward road improvement works have continuously increased, so, it would be considered to be the very time that full-fledged village road improvement policy be initiated.

The Korea Environmental Impact Assessment (EIA) system was introduced in 1977 through the Environmental Conservation Act. It has progressed through many laws and regulations promoting the balance between development and conservation, and functioning as a Preventitive environmental policy. Despite the efforts to minimize environmental damage from development and to uplift social awareness of environmental preservation, deficient impartiality and objectivity in completing and investigating environmental assessments, there have continously existed conflicts among related stakeholder, neglecting arrangements and ineffectiveness of public participation. This research present EIA obstacles and analyzes the overall status of the EIA through surveys from related experts. On the basis of this research, the actual complications regarding the developer, public participation, examiner and consultant are brought about. Also, remedies are proposed to ensure effective EIAs and restore confidence in them.

Design of secure and efficient public-key encryption schemes under weaker computational assumptions has been regarded as an important and challenging task. As far as ElGamal-type encryption schemes are concerned, some variants of the original ElGamal encryption scheme based on weaker computational assumption have been proposed: Although security of the ElGamal variant of Fujisaki-Okamoto public -key encryption scheme and Cramer and Shoup's encryption scheme is based on the Decisional Diffie-Hellman Assumption (DDH-A), security of the recent Pointcheval's ElGamal encryption variant is based on the Computational Diffie-Hellman Assumption (CDH-A), which is known to be weaker than DDH-A. In this paper, we propose new ElGamal encryption variants whose security is based on CDH-A and the Elliptic Curve Computational Diffie-Hellman Assumption (EC-CDH-A). Also, we show that the proposed variants are secure against the adaptive chosen-ciphertext attack in the random oracle model. An important feature of the proposed variants is length-efficiency which provides shorter ciphertexts than those of other schemes.

This study was conducted to investigate provider's behavior change after releasing the information on the Cesarean section rate. Claims data filed at the National Health Insurance Corporation was used for this analysis and the focus of this study was the change of cesarean rate after the public disclosure of information. Average rates of the year 1999 and 2000 were compared, on the institutional basis, and range and coefficient of variation were estimated. For the last decade, Cesarean section rate has been increased dramatically. Clinical or demographic factors could not adequately explain the increase. Instead, nonclinical factors, such as financial incentive, physician's convenience, practice characteristics, etc., were more significant in explaining the increasing rate. Providers' behavior was significantly affected by the public release of information: after the release, average rate was decreased by 10.2%, and variations were also decreased. In particular, the extent of decrease was explained mainly by nonclinical factor rather than clinical ones. The results suggest that disseminating practice information to providers and consumers could contribute to reducing unnecessary medical service.

This study examined how middle-aged jobholders anticipate their living after retirement, how they plan their post-retirement financial welfare and what attitude they have towards old age. The data came from 290 middle-aged male and female people in Incheon, Suwon and Cheongju city and were analyzed to find the differences among public planned pension types, such as the National Pension System (NPS), the Government Employee Pension Corporation (GEPC), and the Korea Teachers Pension (KTP). The major results were as follows: First, the expected income level after retirement in GEPC members was the highest and the lowest in KTP members. Second, the expected living period after retirement is the main criteria used when determining the amount of money needed for old age. Third, KTP members were of the most inferior at financial planning and practice, especially self-reflection of their expending behavior, thrift and saving practice for old age.
