The Article 17 (1) of the Medical Service Act states that no one but medical doctor, dentist or herb doctor shall prepare medical certificate, post-mortem examination, certificate or prescription. Though medical certificate, post-mortem examination or certificate is a private document issued by doctor personally, it is accepted as reliable as public document. Therefore, for medical certificate, post-mortem examination or certificate, unlike other private document to guarantee authenticipy of the content, the Article 233 of the Criminal Act states the Crime of Issuance of Falsified Medical Certificates. In other words, the Criminal Act Article 233 states that If a medical or herb doctor, dentist or midwife prepares false medical certificate, post-mortem examination or certificate life or death, one shall be punished by imprisonment or imprisonment without prison labor for not more than three years, suspension of qualifications for not more than seven years, or a fine not exceeding thirtht million won. The subject of the Crime of Issuance of Falsified Medical Certificates is only a medical or herb doctor, dentist or midwife and the eligibility requirements are specified in the Medical Service Act. Medical certificate is the medical document to be issued by medical doctor to certify the health status and show the Jugdement about the result of the diagnosis, Post-mortem examination is the document to be listed by medical doctor to confirm medically about human body or dead body, and Certificate life or death is a kind of medical certificate to verify the fact of birth or death, the cause of death, such as Birth Certificate, Certificate of Stillbirth or Certificate of Dead Fetus. To constitute the crime of Issuance of Falsified Medical Certificates, it is necessary for the contents of the certificate to be substantially contrary to the truth, as well as it is needed the subjective perception that the contents of the certificate are false. The Supreme Court Decision 2004DO3360 Delivered on March 23, 2006 declared that although the Defendant did not MRI scan, etc. for precise observation about the disability status of Mr Park, it was difficult to believe that the contents of the Disability Certificate of this case were contrary to the objective truth or the defendant had perception that the contents of the certificate were false. I don't agree with the Supreme Court Decision, because the Supreme Court confirmed the decision by the court below despite the Supreme Court should have made the court below retry the reason why the Defendant did not MRI scan, etc. for precise observation about the disability status of Mr Park.

This study was carried out to measure and analyze the vibration levels and modes produced by a hopper type feeder used at laying hen farms, to prevent the vibration resonance and to reduce the vibration of the hopper type feeder (6-tier). The most vibration in a layer house were produced by hopper type feeder as shown the previous study. According to the measurement results, the ratio of transmissibility was as high as 100-638% for natural frequency of 170 Hz or less. And vibration simulations were taken by the results of vibration mode analysis and the weakest points to vibrations were determined accordingly. Then measurement and analysis were taken for those points. The quantities of vibration were 4.6354-4.9118 g($g=9.81^m/s^2$) by axis. In this study, it was found that hopper type feeder generated vibration as much as to influence the ratio of laying eggs of layer. And by the analysis of vibration on the weakest points, design methods and equipment were suggested for isolating/reducing of vibration by each axis.

Since 1992, the sixth national curriculum introduced the policy of school based curriculum development(SBCD) and required all the public elementary schools to develop their own curriculum for the gifted children in their schools. However, in spite of the fact that this curriculum policy for the gifted children has the history of 15 years until now, the current state of its implementation seems to be unsatisfactory. The major reason for that seems to be due to the reality that the schools have not had the theoretical basis for the curriculum development for the gifted children. In this vein, the researcher presented the theoretical SBCD model for the gifted children in elementary schools under the assumption that the model should suit the identity of elementary education, so that the gifted education in the elementary school can be implemented in its own form and adequacy. Based on the identity of elementary education, the model was developed by reformulating three component models of VanTassel-Baska's ICM: content model, process-product model, and epistemological model. The major feature of the researcher's model is to adapt and adjust the three component models differently according to the age level from the first to sixth graders in the elementary school. The model can be used not only as a general model for the talent pool of the school but also as an individual model for a specific gifted child by taking his special needs and characteristics into account. The model is a theoretical one based on the curriculum models for the gifted which were presented by several scholars in the area of G/T education, and it needs to be validated empirically in the future.

At present, the number of local governments using the Traffic Information Center are increasing and drivers are utilizing its traffic information from VMS installed on roads in cities. However, the cases of the user's utility of VMS about urban roads with special characteristics different from expressways and urban highways haven't been evaluated so far. Because VMS is a medium installed from a budget to provide traffic information, it is necessary to evaluate and manage the efficiency of users. This study judged that the efficiency of the drivers using VMS of urban roads most influences the duty on alternative route information provision so that it established its evaluation criteria. In addition, it needs to raise its value by many drivers' observation of VMS. Therefore, in case of the same conditions, the installation location of VMS should be a road section with much traffic volume so its the evaluation criteria was established. At present, the study results can be utilized to raise the user's utility of VMS installed in the urban roads.

Objectives : The purpose of this study was to analyze dental records performed through a dental hygiene process and provide basic data on clinical training education for dental hygienists. Methods : The dental hygiene records of 440 senior dental hygiene students in Y University from March 2005 to September 2008, were examined. The needs of the clients confirmed by the dental hygiene diagnosis was based on Human Need Theory. The client's needs and the number of visits were analyzed according to the general characteristics(gender, age). The contents of the dental hygiene implementation performed according to the needs were divided into dental hygiene care and oral health education. The dental hygiene evaluation was classified into 'Met of Goal', 'Partially Met of Goal', and 'Unmet of Goal' according to the dental hygiene diagnosis. Data analysis was performed for the Frequency statistics and a Fisher's exact test using SPSS 12.0K for Windows. Results : 1. The clients were mostly aged in their 20's(307 clients). 2. The dental hygiene care usually performed was 'Scaling' and 'Recommendation to visit a dental clinic', and the education performed was 'How to brush teeth'. The implementation result from the need to Freedom of Stress was as simple as 'Be careful when treating' and 'Explanation of medical treatment and tools'. 3. The dental hygiene evaluation showed a higher met rate in the field of education than in that of the dental hygiene care. The reason for unmet the goal was 'Lack of the client's efforts and they didn't visit dental clinic'. Conclusions : The search for a range of clients for dental hygiene process should be made through effective connections between the local community institutions and schools. It was suggested that they should be strength the practical exercises for clients suffering dental anxiety and stress in dental treatments. In addition, education and attempts to motivate the clients should be performed according to their characteristics.

Objectives : The purpose of this study was to investigate regional commitment index(RGI) of hospital in Korea, and the relationship RGI and hospital characteristics, such as foundation, region, size. Therefore, we are to suggest fundamental information to make and evaluate healthcare resource policy in hospital- and government-level. Methods : The 'Patient Survey 2002(administered by Ministry of Health and Social Welfare(MOHW)' was analyzed. We selected the patient data of the hospitals above 100 beds. Then, we calculated the RGI, number of same cases divided by all cases in each hospital. By using SPSS/win ver 14.0, statistical analysis such as t-test, ANOVA, correlational and regression analysis was carried out. Results : The results are as follows. 1. Overall mean and standard deviation of RGI were revealed as 0.805${\pm}$0.225 in inpatients, and 0.871${\pm}$0.184 in outpatient. The median of inpatients' and outpatients' RGI were 0.890 and 0.933. The RGI of inpatients of private hospitals were revealed significantly higher than that of the public(public: 0.727, private: 0.822). However, outpatients' RGI was not revealed as significantly different. 2. The RGI of general specialty hospitals were significantly lower than others, therefore we could think that more inpatients and outpatients of general specialty hospitals flowed in from others province or metropolitan cities than other hospital types. 3. The RGI of hospitals holding above 400 beds were significantly lower than others in inpatients and outpatients. 5. The RGI of hospitals were significantly different among sixteen province and metropolitan cities. The RGI inpatients of Gwangju and Daejon metropolitan city were lowest sub-group(0.659, 0.664), and the RGI inpatients of Jeju was revealed as highest, 0.979. 6. Available beds, total doctors, and total employees were negatively correlated with RGI of inpatients and outpatients. 7. The significant influencing factors to RGI of inpatients and outpatients were appeared samely such as available beds, wide healthcare region, hospital size, and foundation type. Conclusions : It is considered that RGI of hospital represent competitive power in healthcare market. Also, the competitive advantage and quality of hospital clustered by characteristics could made out by RGI. Therefore, the results of this study would be useful to develop and evaluate hospital policy of individual hospital or local government.

Porcine reproductive and respiratory syndrome (PRRS) is characterized by reproductive failure in sows and respiratory distress in all age pigs. Porcine respiratory disease complex (PRDC) is a disease caused by opportunistic bacterial infection secondary to a weakened immune system by a preceding respiratory infection. In this study, we tried to compare the immune responses in PRRS and PRDC groups to clearly characterize the disease severity. Eighty-five pigs were infected with various Korean field PRRS virus strains. Infected animals were classified into PRRS (n=32) and PRDC (n=53) groups based on lung lesions such as interstitial pneumonia, suppurative pneumonia, and pleuropneumonia. The immune cell population of bronchoalveolar lavage cells (BALc) was evaluated on 14 and 28 days post infection (dpi) and PMBC cytokine expression was measured on 0, 3, 7, 14 dpi to investigate early inflammatory reactions. Pulmonary lesion severity was negatively correlated with alveolar macrophage (AM) in both PRRS and PRDC groups on 14 and 28 dpi. AM in BALc was less populated in PRDC group on 28 dpi compared to PRRS group. AM in BALc was significantly less populated in PRDC group on 28 dpi compared to 14 dpi. In addition, cytotoxic T lymphocyte (CTL) in BALc was higher populated in PRDC group on 14 dpi and 28 dpi compared to PRRS group. In the case of PBMC cytokine TNF-α, IFN-α, IL-1β, IFN-γ, FoxP3, and IL-2, the PRRS group showed higher expression than the PRDC group on 7 dpi, 14 dpi, 7 dpi, 14 dpi, 14 dpi, and 14 dpi, respectively. On the other hand, in the case of IFN-β, IL-6, IL-8, IL-4, and IL-17, the PRDC group showed higher PBMC cytokine expression at 14 dpi, 7 dpi, 14 dpi, 3 dpi, and 3 dpi, respectively, than the PRRS group. Based on these results, our study could characterize differential immune responses in pigs with PRRS or PRDC.

Lab-scale experiments have been carried out to investigate the effect of F/R ratio of ASBR (Anaerobic Sequencing Batch Reactor) process on the removal of the organic matters in ammonia stripped swine wastewater. Three ASBR inoculated with sludge mixed with granular sludge of UASB (Upflow Anaerobic Sludge Blanket) and anaerobic digested sludge of municipal wastewater treatment plant were operated. Ammonia stripped swine wastewater was used as influent. Prior to conducting the experiments with varied conditions, the effect of increasing organic loading rate from 2.34 to $5.79gTCOD_{Cr}/L$-day at a fixed F/R ratio of 0.1 on the organic removal efficiency has been studied during start-up period. As the result of the experiment, under the condition of varied organic loadings, less than $4.14gTCOD_{Cr}/L$-day, the removed efficiency $TCOD_{Cr}$ of the ASBR process is 83% resulted from the mean value of effluent $TCOD_{Cr}$, 9,125 mg/L during the start-up period. Then ASBRs were operated with F/R ratio of 0.024, 0.303 and 0.91 respectively. Organic loading rate was increased from 4.56 to $15.43gTCOD_{Cr}/L$-day to investigate the effects of F/R ratio and organic loading rate on the organic removal efficiency. As the result of the experiment, less than $6.23gTCOD_{Cr}/L$/L-day, F/R ratio haven't an effect on the organic removal efficiency and the mean removal efficiency of TSS, $TCOD_{Cr}$ and $SCOD_{Cr}$ was about 80%, 86% and 78% at the all of F/R ratio. But as organic loading rate was increased from 8.54 to $12.04gTCOD_{Cr}/L$-day at the F/R ratio of 0.024, the removal efficiency of $SCOD_{Cr}$ decreased from 71% to 63%. The range of decreased removal efficiency of $SCOD_{Cr}$ at the F/R ratio of 0.024 was much more higher than at the F/R ratio of 0.303, 0.91. Thus, as organic loading rate was increased, ASBRs were operated with high F/R ratio to obtain high removal efficiency.

Eleven herbicides were treated in soybean fields of Dukso and Yeoncheon in Gyeonggi province. These herbicides were classified by two-dimensional ordination analysis based on important values of the weed flora which were obtained after application of herbicides. Weed community types were E. crus-galli(56%)-D. adscendens (14%) -C. album (10%)-P. oleracea (8%) and P. oleracea (58%)-E. crus-galli (29%) -A. mangostanus (5%) -D. adscendens (3%), respectively. From soybean field at Dukso, 11 weed community types or 11 herbicide groups were obtained. And at Yeoncheon, 9 weed community types or 9 herbicide groups were classified. At treated blocks with clomazone and bentazon, C. amuricus and E. crus-galli dominated respectively. And at treated blocks with quizalofop, haloxifop and alloxydium, P. oleracea dominated remarkably. The herbicides classification by the two-dimensional ordination analysis could be used more effectively to selecting herbicides for reciprocal and systematic weed control than by similarity analysis.

This experiments was conducted to investigate the dormancy of Eleocharis kuroguwai tuber in the earth and the influence of seeding time and depth on the emergence of Eleocharis kuroguwai. The tuber of Eleocharis kuroguwai on underground was formed the most amount between 10cm and 15cm layer and formed the second a lot of tuber in the soil layer between 5cm and 10cm, the third between the surface of the earth and 5cm, the least between 15cm and 20cm. The total mean emergence of tuber was 78%, and the dormant tuber was approximately 22% of total tuber formed during a year in the earth. The distribution of dormant tuber under the ground was about 42% between 15cm and 20cm, 39% between 10 cm and 15cm, 14% between 5cm and 10cm, and 5% between the surface of the earth and 5cm. The dormancy percent of tuber formed at each soil layer was about 60% between 15cm and 20cm, 21% between 10cm and 15cm, 12% between 5cm and 10cm, and 7% between the surface of the earth and 5cm. The emergence days of the tuber seeded at low layer was short, and the emergence rate was high, The tuber was formed much more on seeding at May 30th than June 30th.
