In this study, FLUENT v.16.1 was used to investigate the compressible flow generated by the supersonic jet spewed from a high pressure tube. As the boundary condition for CFD (Computational Fluid Dynamics) analysis, the inlet temperature of air was constantly 300 K and the variation of JPR (Jet Pressure Ratio) were 5, 50, 100, 150 and the variation of tube diameter were 10, 20, 30 cm. As a result, it was confirmed that the effective range was increased as the JPR was higher, but it was confirmed that the effective range was lower than the JPR rise, and that the effective range was increased as the diameter was larger. Therefore, it is found that the tube diameter is more sensitive than the JPR among the influence factors of jet, and if the result of this study were reflected in the design of high pressure system, it will contribute to the design of the system for preventing the second accident.

For the purpose of developing Korean Herbalogy with the plants of Lauraceaewhich grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigated and the results obtained as follows: 1. There were totaled to 8 genera and 20 in Korea and among them medicinal plants are 5 genera, 10species, some 50% in total, but the number of species may be added because of the similiar plants. 2. According to sum of 20 species in Lauraceae family, they were classified into Lindera genera 7, Cinnamomum genera 3. Thus it was noticed that Lindera genera was the main kind in total. 3. According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Lauraceae family were classified as Radix 3, Foilum 4, Fructus 4, Cortex 5. So Cortex is 50% of all and it is the most applied in the clinical treatments. 4. According to nature and flavour of medicinal plants, they were classified into warmth 15; pungent taste 18 thus it was noticed that warmth and pungent taste is the main in nature and flavour of medicinal plants 5. According to meridian tropism of herbs they were classified into liver meridian 6, stomach meridian 6, spleen meridian 5 thus it was noticed that liver meridian and stomach meridian is the main kind 6. According to the Properties and Principal curative action, they were classified into drugs for expelling wind 10, drugs for relieving pain 11. Thus it was noticed that drugs for relieving pain was the main kind 7. It was researched that toxic drugs include minor toxin were 2 kinds From this result, it was revealed that Cortex was the main kind in the plants for medical purpose of Lauraceae. And toxic plants was slightly poisonous that it will be used for clinical treatments more easily. It is considered that many experiments and clinical approaches must be continued to use Lauraceae plants widely.

For the purpose of developing Korean Herbalogy with the plants of Rosaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigated and the results obtained as follows: 1. There were totaled to 36 genera and 262 in Korea and among them medicinal plants are 27 genera, 117species, some 44% in total, but the number of species may be added because of the similiar plants. 2. According to sum of 262 species in Rosaceae family, they were classified into Agrimonia genera 3, Potentilla genera 26, Prunus genera 48,pyrus genera 17, Rosa genera 24, Rubus genera 28, Sorbaria genera 17, Spiraea genera 20. Thus it was noticed that Prunus genera was the main kind in total. 3. According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Rosaceae family were classified as Herba 24, Radix 43, Foilum 31, Fructus 48, Semen 11, cortex 14, Lignum, Ramulus;12 each Flos 3, pericarpium 3, resina 2, the others 6. so Fructus is 24% of all and it is the most applied in the clinical treatments. 4. According to nature and flavour of medicinal plants, they were classified into balance 84, warmth, heat; 44 each, cold, cool; 35 each bitter taste 79, sweet taste 74, sour taste 61 thus it was noticed that balance and bitter taste is the main in nature and flavour of medicinal plants 5. According to meridian tropism of herbs they were classified into liver meridian 50 lung meridian 28, stomach meridian 22, spleen meridian 20, heart meridian 19 thus it was noticed that liver meridian is the main kind 6. According to the Properties and Principal curative action, they were classified into drugs for treating detoxicant 72, drugs for treating febrifugal 55, drugs for invigorating blood circulation 53, drugs for removing dampness 46, drugs for expelling wind and drugs to stop bleeding 38 each, drugs to cure tramatic swelling and drugs for relieving pain 36 each. Thus it was noticed that drugs for treating detoxicant and febrifugal was the main kind 7. It was researched that toxic drugs include minor toxin were 10 kinds From this result, it was revealed that Fructus was the main kind in the plants for medical purpose of Rosaceae. and toxic plants was slightly poisonous that it will be used for clinical treatments more easily. It is considered that many experiments and clinical approaches must be continued to use Rosaceae plants widely.

For the purpose of developing korean herbalogy with the plants of Epilobiaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroghly investigated and the results obtained were as follow: 1. There were totaled 29 species in Korea and among them medicinal plants are 12 species may be added because of the similiar plants. 2. According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Epilobiaceae family were classified as Herba 10, Radix 3, Semen 1. Thus it was noticed that the Herba were main kind. 3. According to sum of 29 species in Epilobiaceae family, they were classified into Epilobium genera 16, Circaea genera 6, Oneothera genera 3, Fuchisia genera 2, Ludwigia genera 2. Thus it was noticed that Epilobium genera was the main kind, same 55% in total. 4. According to nature and flavour of medicinal plants, they were classified into warmth and heat:3, cold and cool:11, balance 7. Thus it was noticed that cool and cold is the main in nature and flavour medicinal plants. 5. Comparing to whole medicinal plants 12 kinds, toxic drugs include minor toxin were 2 kinds, 7% of the whole. From this result, It was revealed that the plants for medical purpose in Epilobiaceae was 41% kinds of whole, herba and radix were abundunt, toxic plants were so rare that it will be used for clinical treatments more easily. It is considered that clinical experiments and approaches should be continued to use Epilobiaceae plants widely.

Paragonimiasis is an infectious disease caused by ingestion of freshwater crab, crayfish, or shrimp infested with Paragonimus metacercariae. Here, we report a case of extrapulmonary paragonimiasis presenting as an abscess in the abdominal cavity. A 54 year old woman presneted, compaining of severe abdominal pain. Her abdominal CT showed an abdominal abscess with peripheral rim enhancement and central hypodensity core on omentum and terminal ileum. We decided to perfom a diagnostic laparoscopic exploration for acute abdominal pain. During surgery, we saw a living adult worm in the abscess pocket. We diagnosed paragonimiasis and treated with Praziquantel. This case was confirmed by biopsy and micro-ELISA test.
