In the Part I, the three dimensional model testing with NNW deep water wave direction gave the results such that the occurrence of breaking waves over the peak of Ear-Do caused very small wave height at the structure position. But the measured wave forces were rather greater than the calculated forces based on deep water wave height. Furthermore, It was also perceived that the time series of the forces looked like corresponding to the case that waves were superimposed by an unidirectional current. In the present Part II, the current is presumed to be a flow secondly induced by breaking waves, and an extensive study to clarify the current in a quantitative sense is performed through numerical analysis and hydraulic experiment. The results showed that a strong circulation can surely occur in the vicinity of the structure due to radiation stress differentials given by the breaking waves. It was also recognized that the velocity of the induced current varied with the magnitude of energy dissipation rate introduced in the numerical analysis. The numerical analysis was tuned adjusting the dissipation rate so that the calculated wave field could closely match with the experimental results of Part I. The fluid force (in prototype) for the optimal match showed approximately 2.2% increased over the calculated value based on the deep water wave height (24.6m) whereas the force corresponding to the average of the experimental values showed the increase of about 13.0%.

The objectives of this experiment was to evaluate the effect of seeding and transplanting date on yield and quality of rapeseed experiment were conducted in the research field of Chungcheongnam Do(Taejun) Agricultural Research and Extension Services with Yudal, one of the rapeseed cultivar of different growth characteristics among the six treatments were examined and recorded. Results showed that yield components such as plant height, length of ear and pod, number of branches and pods and percentage of pod setting and seed set were highest at the plot with direct seeding in Sep. 10. In this treatment yield of seed, 1,000 grains weight and weight of $1{\ell}$ were highest. On the basis of vegetative and yield parameter of direct seeding in Sep. 10 was the best sowing date of rapeseed crop in Chungcheongnam Do region of Korea. Experiments were conducted in the research field of Chungcheongnam Do(Taejun) Agricultural Research and Extension Services with Yudal variety, which showed different growth characteristics. Yield components such as plant height, length of ear and pod, number of branches and pods and percentage of pod setting and seed set were highest at the plot with direct seeding in Sep. 10. Yield of seed, 1,000 grains weight and weight of $1{\ell}$ were highest at the direct seeding in Sep. 10. Judging from the results reported above, seemed to be direct seeding in Sep. 10.

Sopung-san(SPS; prescription No. DO27), a herbal medicine prescribed by oriental hospital of Daegu fanny University, has been used as cure for pruritus and psoriasis. To evaluate anti-inflammatory effect of Sopung-san, we treated Sopung-san extract in animal model system induced contact hypersensitivity. Contact hypersensitivity, a local inflammatory response of the skin, was induced by 1% DNCB on the right ear of BALB/C mouse. Sopung-san was prepared as water extract and administrated everyday for 2 weeks per oral. A right ear of mouse was potently swelled by 1% of DNCB treatment, but a mouse ear thickness was significantly reduced by Sopung-san after 2 weeks. treatment. Sopung-san reduced IgG in serum obtained from blood of 1 % DNCB-treated mouse. IgE in serum was not changed by DNCB and/or Sopung-san treatment. $IL-1{\beta}$ and IL-6 from ear tissue were significantly increased by DNCB, Dut were not reduced by Sopung-san. From these results, anti-inflammatory effect of Sopung-san, especially reduction of ear swelling, might be partly due to reduction of IgG in serum.

Our previous report demonstrated that certain flavonoid aglycones such as apigenin (flavone), quercetin, morin (flavonols), and biochanin A (isoflavone) showed in vivo antiinflammatory activity via topical and oral routes of adminstation. As a continual study, the various flavonoid glycosides have been evaluated in mouse ear edema assay using archidonic acid or croton-oil as a inflammagen. Flavonoids were orally administered (2 mg/mouse) and ear edema inhibition was measured. Significant antiinflammatory activities were found esepcially in flavone and flavonol glycosides (15-29% inhibition) although the flavonoid derivatives tested showed less antiinflammatory activity than hydrocortisone or indomethacin. Chalcone and flavanone derivatives were not significantly active. And in general, flavonol glycosides of kaempferol-type were found to have a higher oral antiinflammatory activity than that of flavonol glycosides of quercetin-type in mice.

Background: Lobular keloid appears to be a consequence of hypertrophic inflammation secondary to ear piercings performed under unsterile conditions. We wish to understand the pathogenesis of lobular keloids and report operative outcomes with a literature review. Methods: A retrospective review identified 40 cases of lobular keloids between January, 2005 and December, 2010. Patient records were reviewed for preclinical factors such as presence of inflammation after ear piercing prior to keloid development, surgical management, and histopathologic correlation to recurrence. Results: The operation had been performed by surgical core extirpation or simple excision, postoperative lobular compression, and scar ointments. Perivascular infiltration was noted in intra- and extra-keloid tissue in 70% of patients. The postoperative recurrence rate was 10%, and most of the patients satisfied with treatment outcomes. Conclusion: Histological perivascular inflammation is a prominent feature of lobular keloids. Proper surgical treatment, adjuvant treatments, and persistent follow-up observation were sufficient in maintaining a relatively low rates of recurrence.

Chronic headache is one of the most common symptoms of outpatients. There are many approaches to treat chronic headache, but it is difficult to be resolved completely. So analgesics-addicted patients are increased in numbers. Acupuncture and ear-acupuncture have been used for relief headache. But it is not sufficient to compare the effect of acupuncture on several chronic headache groups. Thus we investigate the effect of acupuncture and ear-acupuncture on several chronic headache groups and analgesics-abused groups. We researched 36 patients who were treated at Department of Acupuncture & Moxibustion, Kyung Hee Medical Center from August 1998 to July 1999. The chronic headache patients were classified into tension-type headache group, migraine group and unclassified headache group by Guide of IHS. Each group was treated with acupuncture and ear-acupuncture. The effect was assessed through questionnaires and self-rating headache index.

Objective : This study was designed to find out whether placebo auricular acupuncture is able to be constituted as an appropriate control group for needle insertion to Korean. Methods : We performed a randomized controlled, single-blind study(n=48) comparing subjective evaluations of needles insertion and avoidance of needles insertion. Both ears were needled concurrently, one real acupuncture(needle insertion) and the other placebo acupuncture(avoidance of needle insertion with blunt tip). Subjects then completed a questionnaire rating the intensity of five sensations in each ear, and also attempted to identity which ear received placebo and which ear received real acupuncture. Results : As for the effects of real and placebo acupuncture on each item(Warmth, Fullness, Pain, Activity, Radiating), real acupuncture was significantly warmer, fuller, more painful than placebo acupuncture. In particular, the real acupuncture only in experienced acupuncture recipients was significantly warmer, fuller, more painful than placebo acupuncture. About the ability to differentiate real and placebo acupuncture, 54.2 percent correctly identified which ear received real acupuncture and which ear received placebo acupuncture. However, the ability to differentiate real and placebo acupuncture for naive and experienced acupuncture recipients was not significantly different. Conclusions : Most of the subjects(Korean) identified which ear received placebo and which ear received real acupuncture. We found that this placebo auricular acupuncture is not able to be applied to Korean, in particular for experienced acupuncture recipients. Further study is needed for new placebo auricular acupuncture or racial difference between American.
