The purpose of this study was to find out what changes in weight bearing in the both upper extremities occurred in response to Asymmetrical Tonic Neck Reflex by rotation of head in the quadruped position. The subjects for the study were 80 children (44 male, 44 female) who were neurologically normal. They were divided into two groups $6\~7$ year olds and $8\~9$ year olds. Paired t-test was applied as a atatistical method at the 0.01 level of significance. The results of this study are as follows; 1. In the neutral position of head, there was mort weight bearing on the left hand than the right in both of the two groups(p<0.01). 2. When the head was rotated to the right or left passively, there was more weight bearing on the hand of side to which the face was rotated(p<0.01). 3. When the head was rotated to the right or left actively, there us also more weight bearing on the hand of side to which the face was rotated(p<0.01). Therefore, it is possible to un Asymmetrical Tonic Neck Reflex to increase body weight for muscle strengthening in children with weakened muscles of the upper extremities. further studies are required for confirmation of these findings.

Caprine arthritis encephalitis (CAE) virus is a causative agent of caprine arthritis-encephalitis. In our previous study we reported a prevalence of CAE. In this study, we described the further detailed pathological features of CAE and examined the detection of virus by in situ hybridization (ISH). Histopathologically, interstitial pneumonia and bronchopneumonia in lung, focal inflammation in mammary glands, perivascular cuffing in brain, arthritis, and focal necrosis, mild steatosis, inflammatory cell infiltration of liver were noted. CAEV proviral-DNA was identified by nested polymerase chain reaction (PCR) in blood cells, brain, synovial fluid, and lymph node. Confirmation by nested PCR involved amplification of a 296 bp ($1^{st}$ PCR) and 185 bp ($2^{nd}$ PCR) fragments corresponding to a conserved region on the gag gene of CAEV. Positive ISH signals were detected in the brain and liver. In conclusion, significant histopathological findings included parenchymal infection in various organs, including the lung, liver, brain, joint, and mammary gland were noted in the CAEV infected dairy goat. ISH can help confirm the diagnosis of CAE in formalin-fixed samples.

Even though driving under the influence of drug (DUID) is a worldwide problem, we, Korea has no regulation system yet except for alcohol, and there are little cases reported related to DUID. In order to investigate the type of abused drugs for drivers in Korea, we tried to analyze controlled and non-controlled drugs in alcohol-positive blood samples. 275 whole bloods, which were positive for alcohol on the roadside test, were collected from the police for two months ($Nov.{\sim}Dec.$ 2006). The analytical strategy was constituted of three steps: First, alcohol in blood samples were confirmed and quantified by gas chromatography. Second, controlled drugs were screened by $Evidence_{investigator}\;^{TM}$ (Randox, U.K.) as preliminary test. It was based on immunoassay by biochip array analyzer. Nine groups of drug abuse were screened: amphetamines, methamphetamines, cannabis, cocaine, opiates, barbiturates, methadone, benzodiazepines I (oxazepam) & II (lorazepam). Finally, confirmation of these drugs was performed by GC-MS. Blood samples were extracted by solid-phase extraction by $RapidTrace^{TM}$ (Zymark, U.S.A.). After trimethylsilyl (TMS) derivatization, eluates were analyzed to GC-MS. Total 49 drugs were investigated in this study including controlled drugs, antidepressants, 1st generation antihistamines, dextromethorphan, nalbuphine, ketamine, etc. For rapid detection, we developed the automated identification system. It was made up a new software, "DrugMan", modified Chemstation data analysis menu and newly developed macro modules. A series of peak selection, identification and reporting of the results were performed automatically by this system. Concentrations of alcohol in 275 blood samples were ranged from 0.011 to 0.249% (average, 0.119%). Among 149 blood samples, just six samples (4.0%) were showed positive results to the immunoassay: one methamphetamine and five benzodiazepines group I. By GC-MS confirmation, only benzodiazepines were detected and methamphetamine was not detected from immunoassay positive blood sample. Besides these drugs, 5 chlorpheniramines, dextromethorphan, diazepam, doxylamine, ibuprofen, lidocaine and topiramate were also detected in whole bloods by GC-MS. Conclusively, the frequency of drug abuse for Korean drivers was relatively low. There was none case which illegal drug was detected. However these results were limited to alcohol positive blood samples, so it is necessary to analyze more samples including alcohol negative blood.

Purpose: The authors have experienced various lesions that simulate ganglion of the foot on the ultrasonography. The purpose of this study is to evaluate ultrasonographic findings of soft tissue lesions, which were interpreted as ganglion but confirmed as different lesions in the foot. Materials and Methods: We reviewed a database of patients with ganglion on the ultrasonography from two different institutions. There were 109 patients who underwent both ultrasonography and surgical confirmation. Twenty one lesions were identified, of which initial interpretation on the ultrasonography included ganglion which pathology revealed to be different lesions. All images were evaluated by one musculoskeletal radiologist, regarding size, margins, internal echogenicity of lesions, and presence of posterior enhancement. Results: Of 21 lesions, there were 6 fibrous tumors including fibroma, giant cell tumor of tendon sheath, and fibromatosis, 3 hemangiomas, 2 epidermal inclusion cysts, 2 chondromas, 2 angioleiomyomas, 1 trichilemal cyst, 1 neurofibroma, 1 granular cell tumor, 1 neurilemmoma, 1 neuromyxoma, and 1 nodular hidradenoma. Mean size of the lesion was 1.1 cm. Margins were smooth in 10, mild lobulation in 8 and marked lobulation in 3 lesions. Lesions were hypoechoic in 16, anechoic in 4 and isoechoic in 1 case. Posterior acoustic enhancement was definitely present in 5 lesions. Conclusion: On the ultrasonography, various soft tissue lesions of the foot may be confused with ganglion. During surgical resection care should be given even to a simple ganglion as it might turn up to be a solid lesions such as fibrous tumors.

For the first time Pb, Ni, and Cu nanocomposites were synthesized by versatile solution combustion synthesis using Aloevera extract as a reducing agent, to study the potential applications in X-ray/gamma, neutron, and Bremsstrahlung shielding. The synthesized Lead-Nickel-Copper (LNC) nanocomposites were characterized by PXRD, SEM, UV-VIS, and FTIR for the confirmation of successful synthesis. PXRD analysis confirmed the formation of multiphase LNC NCs and the Scherrer equation and the W-H plot gave the average crystal sizes of 19 nm and 17 nm. Surface morphology using SEM and EDX confirmed the presence of LNC NCs. Strong absorption peaks were analyzed by UV visible spectroscopy and the direct energy gap is found to be 3.083 eV. Functional groups present in the LNC NCs were analyzed by FTIR spectroscopy. X-ray/gamma radiation shielding properties were measured using NaI(Tl) detector coupled with MCA. It is found to be very close to Pb. Neutron shielding parameters were compared with traditional shielding materials and found LNC NCs are better than lead and concrete. Secondary radiation shielding known as Bremsstrahlung shielding characteristics also studied and found that LNC NCs are best in secondary radiation shielding. Hence LNC NCs find shielding applications in ionizing radiation such as X-ray/gamma and neutron radiation.

Bangladesh that is known as the poorest country of the world has the large land of fertile soil and very good environment to live, even though we think she may be very bad to live. People being habituated to that good environment, the population explosion made the people to be starven, but the treatment has been simple support without deep analysis of the root of poverty. As the result it is general that the poverty is severer and severer in spite of continuous support. For the last century Korea changed from the country of poverty and despair to that of development and hope, to be model mid vision of under development countries including Bangladesh. At this point it is necessary to look back the way of development to help them to solve their poverty problem. That is the goal of this project, and this thesis is the result of it. It is evaluated for the 1st 5 years work of the project to apply the result to the next 5 years plan. This project had been proceeded from 1. Jul. 1990 to 30. Jun. 1995 at Chilmari area of Bangladesh, with teaching and training to wake up the mentality of the people, demonstration farming and cooperative association. It was proceeded as the Agriculture project of KDAB(Korean Development Association in Bangladesh, an NGO registered to Bangladesh) supported by Good Neighbors, KOICA and many churches and individuals. Especially the teaching and training work was proceeded as the branch of the Canaan Farmer`s School of Korea with instruction and support. After the basic survey for project, the confirmation of working place and the preparation of training facility, 10 times of long term training(3 months worse, boarding) was completed, with many times of short term training, informal training, demonstration farm, various demonstrating works. The results of the work are understanding of the not of problem by participatory observation, making plan to solve it, getting the trust from the people and beginning the practical work with the trainees for development of economy and living situation. The biggest problem of Bangladesh is being understood losing the desire to solve the poverty problem and the self-confidence to be able to do it. It is the conclusion that after solving the problem of thought and mentality, the education, technology and money can be effective for development. So the 1st 5 year project is evaluated as the basic work to analyse the root of problem, to chance mentality of people and to search income source. The next goal is to promote practical living level of people. For that it is necessary to develope die mentality of people including responsibility and self-confidence by teaching and training, to educate cooperative association and technology for economical development, to proceed integrated rural development work with economical development, educational improvement and reformation of environment. It is very important result that they decided to grow poultry for main economical source of Chilmari area, to do economical development work by joint operation of poultry through cooperative association.

Objectives : The purpose of this study is to investigate the effect of mixed pharmacopuncture of $Jungsongouhyul$ and $Cervi$ $Pantotrichum$ $Cornu$ on low back pain patients. Methods : 83 patients with Low back pain who were treated in Dept. of Acupuncture and Moxibusion, Dongshin University Hospital in Suncheon from Sep. 1st, 2010 to August 31th, 2011, were divided into two groups. One group (52 patients) was treated with conservative treatments (acupuncture, herb med, cupping therapy and physical therapy) and mixed pharmacopuncture of $Jungsongouhyul$ and $Cervi$ $Pantotrichum$ $Cornu$ theraphy (PG) and the other group (31 patients) was treated with conservative treatments alone(NPG). To estimate the effects of treatments, visual analog scale(VAS) and Oswestry disability index(ODI) were checked. Results : 1. In VAS, both of PG and NPG shows statistically significant improvement rate after 3rd treatment and 5th treatment. 2. In ODI, both of PG and NPG shows statistically significant improvement rate after 3rd treatment and 5th treatment. 3. In comparing VAS of PG and NPG, there was more significant improvement in PG than NPG after 3rd treatment and 5th treatment. 4. In comparing ODI of PG and NPG, there was more significant improvement in PG than NPG after 3rd treatment but no significant improvement between PG and NPG after 5th treatment. Conclusions : According to the study, it is thought that mixed pharmacopuncture of $Jungsongouhyul$ and $Cervi$ $Pantotrichum$ $Cornu$ theraphy is effective to low back pain patients, and further study is needed for the confirmation of the effect of mixed pharmacopuncture of $Jungsongouhyul$ and $Cervi$ $Pantotrichum$ $Cornu$.
