Olive flounder (Paralichthys olivaceus) is the major mariculture fish in Korea. The annual aquaculture production of olive flounder in Korea during the period of 2003 was 300,000 ton (2002 Statistics, Ministry of Maritime Affairs & Fisheries, Korea Government). Anesthetics is very necessary in aquaculture to minimize stress and damage during harvesting, grading, transportation, spawning induction and handling to fish. In the present study, isoeugenol as new anesthetic in marine fish, especially olive flounder, was examined to know the efficacy and proper concentration. As a result, olive flounder adult was exhibited sedation at 5 ppm at 10 and $15^{\circ}C$, and 7.5 ppm at $20^{\circ}C$, respectively. Anesthesia was required at least 10, 7.5 and 10 ppm at $10^{\circ}C$, $15^{\circ}C$ and at $20^{\circ}C$, respectively. In case of fry, the effect of sedation was observed from 2.5 ppm at $10^{\circ}C$ and 5 ppm at 15 and $20^{\circ}C$, respectively. Anesthesia was observed from 2.5 ppm at $10^{\circ}C$, 5 ppm at 15 and $20^{\circ}C$, respectively. In acute toxicity test, it was impossible to explore $LD_{50}$ with the concentration of isoeugenol adult at $15^{\circ}C$ used, but over immersion volume of 15 ppm at $15^{\circ}C$ was observed mortality in fry. Based on the present study, isoeugenol was identified as a safe and active anesthetic to olive flounder.
As the population is getting older, medical expenses amount of the whole is keep increasing. So, the pressure of the finances, Health Insurance, Medical Care Assistance Act and etc, is getting higher. The share of healthcare-expense is increasing due to elderly illness. And it became a social problem; we analysed present state of senior healthcare in South Korea-looked into current laws and policies, and found problems. We tried to suggest improvements that drew from the current state of foreign country senior healthcare of those problems. For the result, we found the problem in relevant-law system of senior healthcare guarantee. In this study, we proposed the ways to qualitatively upgrade of medical standard that considered on elderly' features: the strengthened guarantee for healthcare, financial secure for long-term convalescence benefit, linking and functional reinforcement for elderly welfare and long-term convalescence insurance, the solution for overlapped laws about convalescence in long-term convalescence insurance and elderly welfare, a betterment of grading, and a home service consolidation. We need to secure right amount of emergency medical service budget, and effective management system for the improved level of senior severely emergency medical service. Furthermore, we suggested that South Korea needs to legislate [The Law for Senior Medical Secure] to respond to rapidly increasing senior healthcare fee.

The industrial development of Goryeong County was started by the operation of the Ssangrym Agro¬industrial complex in the 1980s. As of 2m3, there are 6 industrial complexes in Goryeong County which account for 80 percent of total employment and 67 percent of total production outPuts in local manufacturing. The local manufacturing industries grew steadily before the 1997 financial crisis which resulted in industrial decline and have shown again a growing tendency since 2000. In this period of growth, manufacturing outPuts are increased and the industrial structure are improved, while employment and value added are in stagnation. The major industrial agglomerations are based in Gaejin-Myun, Dasan-Myun and Ssangrym-Myun, all of which are those in which the agro-industrial complex is operated. More than half of local manufacturing finns are those which came to move in from other regions, looking for cheap labour forces, agglomeration of the related finns and the easy accessibility to transport and communication. However, such local advantages are increasingly losing due to the shortage of labour forces and the lack of industrial networks. Some policy agendas can be suggested as follows. First of all, industrial policy should attempt links with the building-up of the Daegu Technopolis and the up-grading of the local industrial structure towards the knowledge-based industries. Secondly, the local government should make efforts to establish the innovation supporting system for local firms and the industrial and residential basis.
The purpose of this study is to analyze factors affecting a grade maintenance of long-term care service users. Using 2008-2014 long-term care raw data of National Health Insurance Service(NHIS), the predictors were examined through the logistic regression by long-term care beneficiaries of grade. The results showed that there are differences by 3 factor groups and grade groups(1-3 grade). In socio-demographic factors, in the 1, 3 grade, Individuals 64 or younger presented a much higher probabilities of the grade maintenance than those 85 and over. In the 3 grade, people of living alone, resident of rural area presented a much higher probabilities of the grade maintenance than others. In disease factors, In the 1 grade, people with dementia presented a much higher probabilities of the grade maintenance than other 2, 3grades. In the 2 grade, people with stroke, fracture presented a much higher probabilities of the grade maintenance than others. In the 3 grade, people with cancer presented a much higher probabilities of the grade maintenance than others. In service factors, In the 2, 3grade, people having more renewal numbers presented a much higher probabilities of the grade maintenance than others. In the 1 grade, people who use facility benefits for more days presented a much higher probabilities of the grade maintenance than others. In the 2 grade, people who use in-home benefits for more days presented a much higher probabilities of the grade maintenance than others. Based on the finding of study, implications and future research directions were discussed for policy considerations.

Purpose: The purpose of this study was to correlate the degree of sonographic medial meniscal extrusion with MRI and arthroscopic findings. Materials and Methods: Out of these 32 patients, with medial meniscal tear who went on arthroscopic surgery, 14 patients had the medial meniscal tear and 18 patients had both lateral and medial meniscal tear. The extent of meniscal extrusion without meniscal tear was assesed in 24 patients who did not show meniscal tear on MRI. The extent of meniscal extrusion was measured between tibial medial joint line (excluded osteophyte) and the outer margin of the medial meniscus. Kellgren-Lawrence grading scale was assessed in plain X-ray image and the location of lesion was assessed during arthroscopic surgery. We also measured the extent of meniscal extrusion on MRI and sonography respectively, and compared each other. Results: There was significant difference between patients with medial meniscal tear and both lateral and medial meniscal tear, patients with medial meniscal tear, patients with both medial and lateral meniscal tear, patients without meniscal tear (P value<0.05). Conclusion: The Meniscus tear must be considered when sonography shows the meniscal extrusion more than 5 mm in length.

Objective : The aim of this study is to assess the ability of the CPT test to dignosis radiculopathy in Korean with NeuvalTM CPT database. Method : Electrical stimulation(at 2000, 250, and 5Hz) using Neurometer was applied to the 19 patients who felt back and sciatic pain with herniated intervertevral disc(HIVD) of L-spine, dignosisd by lumbar CT or MRI, and the 33 patients who felt only back or hip or leg pain without HIVD, stenosis, spondylolisthesis which causing radiculopathy. The test sites were toe1, toe3 and toe5 related to L4, L5 and S1 nerve roots. Results : The mean values of the CPT of HIVD group was stiatically lower than LBP group at toe1-250Hz, toe3-2000Hz, 250Hz and toe5-250Hz, 5Hz. The grading CPT score of HIVD group was stastically higher than LBP group at the toe3(L5). The VAS of HIVD group was stastically higher than LBP group. Conclusion : These results suggest that the CPT test can be a valuable testing for diagnosing radiculopathy in Korean. In using CPT test further study is needed for the diagnosis and evaluation of sensory nerve dysfunction in the musculoskeletal disease.

Objectives : The purpose of this study is to investigate the effect of cervical Chuna treatment for Bell's palsy. Methods : We investigated 30 patients with Bell's palsy who had visited at Department of Acupuncture & Moxibustion, of Korean Medicine Hospital Dong-Eui University from June $1_{st}$, 2013 to April $15_{th}$, 2014. Subjects were randomly divided into two groups. Group A(experimental group) was treated by Korean-Western combination treatment with Cervical Chuna treatment and group B(control group) was treated by Korean-Western combination treatment without it. The cervical Chuna treatment was done twice a week, for a total of 8 times. We evaluated the change of each group by using Yanagihara's unweighed grading system. Results : Yanagihara's score in group A was significantly improved during each period from the first visit to four weeks later. However, Yanagihara's score in group B was significantly improved except during first week. The improvement of Yanagihara's score in group A is higher than group B during every period. And significant differences were shown after two weeks from the first visit between the two groups. Conclusions : These results suggest that cervical Chuna treatment may be effective for Bell's palsy.

Objective: In vitro fertilization (IVF) and a prolonging the time of culture may be helpful in establishing a viable pregnancy through a selection effect. Some embryos do not develop beyond the 4-cell stage and some may not develop to the blastocyst stage. We have evaluated the safety of SET and the outcomes of pregnancy. Methods: Sperms were treated with Ham's F-10 supplemented with 10% human follicular fluid (hFF). oocytes or fertilized oocytes were cultured in Dulbecco's Modified Eagle Medium (DMEM) with 10% or 20% hFF respectively. Up to five oocytes were inseminated with approximately 200,000 sperm cells/2 ml in each well. Fertilization was examined in the following morning and fertilized oocytes were co-cultured until embryo transfer. Vero cells for co-culture were prepared in Tissue Culture Medium - 199 (TCM-199) with 10% fetal bovine serum. At the two to four cell and blastocyst on day 2 and day 5, embryo and blstocyst grading were evaluated. Pregnancy rate was determined after transfer of human embryos at the two to four cell stage on day 2 (Group I) or subsequent transfer of embryos on day 2 and at the blastocyst stage on day 5 (Group II). For statistical analysis, Student's t-test and Chi-square (${\chi}^2$_test) were used. Results were considered statistically significant when p value was less than 0.05. Results: No differences was found in the fertilization between Group I (81.0%, 98/121) and Group II (81.8%, 180/220). In case of cleavage rate, no difference was found in Group I (95.9%, 94/98) and Group II (97.8%, 174/178). However, the rate of-clinical pregnancy was significantly higher (p=0.014) in Group II (66.7%, 12/18) than in Group I (26.3%, 5/19). Conclusion: The results of this study showed that SET is safe and effective, and significantly increases the pregnancy rate.

Postharvest nut quality, and changes of soluble solids content and kernel hardness during cold storage in 13 Korean prevailing chestnut cultivars were investigated to establish the chestnut grading and standardization for marketing and processing industry. Chestnut quality attributes such as nut weight, soluble solids content, kernel hardness, % with the pericarp split, and % of polyembryonic nuts were measured from 2001 to 2005. There were significant difference among cultivars in quality characteristics, and also annual variation within same cultivar, corresponded to the high genetic and environmental variability. During cold storage at $2^{\circ}C$ for 16 weeks, remarkable changes in soluble solids content were observed, and Isseumo showed the highest increase of 8% at 16 weeks of cold storage compared with postharvest. In case of most cultivars except early ripening cultivars, soluble solids content of chestnut increased until 12 weeks during cold storage, followed by decreased gradually thereafter. Kernel hardness of most cultivars except lshizuchi during cold storage increased slightly, but it was not statistically significant. This work would be a useful reference to the quality of each chestnut cultivar for the growers and breeders alike.

In this study we tried to develop a biological method for evaluating environment using the potter wasps as an indicator. Wasp species in family Eumenidae, were collected from 13 locations including agricultural area using nest trap. The wasps collected were classified and selected candidate species as an environmental evaluation indicator. Seven species were collected and the Anterhynchium flavomarginatum was the most dominant species. The number of the nest of potter wasps was 12.8/m both in the non-fertilizer and the non-pesticide areas and 7.2/m in the general agricultural areas. The number of nests was 13.4/m in the location where the Degree of Green Naturality (DGN) was high (4.28) and it was 1.2/m where the DGN was low (1.00), suggesting that the index of both richness and diversity tend to increase in locations with more nests. Based on these results, A. flavomarginatum, Orancistrocerus drewseni (Saussure), Isodontia nigellus and Chalicodoma sculpturalis were selected as indicator species for the evaluation of environment including agricultural ecosystem. And a standard for grading an environment (I to IV) was made based on the occurrence, the total number of nesting and the species diversity of potter wasps.
