Hornbeam trees(Carpinus laxiflora BL.) are growing in Korea and have good characteristics such as relatively high density, fine texture, split- resistance, and white colour. However, they have seldom been used as manufacturing materials This study was carried out to evaluate the possibility of using hornbeam wood as bent, wood furniture materials. Softening methods were steaming and micro-wave heating. The specimens of $15{\times}15{\times}350mm$ were used green or air-dried, and were steamed at $100^{\circ}C$ for 20min, or microwave heat ed f or 60 seconds. The bending processing conditions are showed in Table 3. The minimum solid-bending radii of air-dried wood were 40mm for steaming and 200mm for micro-wave heating, respectively. And that of green wood were 40mm for micro-wave heating. In conclusion, both of the steamed wood and micro-wave heated green wood showed very good solid bending processing properties, but micro-wave heated air-dried wood were not sufficient for bent-wood furniture.

Objectives: To inform a clinical case of a refractory levator ani syndrome, that was improved by treatments of traditional Korean medicine (TKM). Methods: A 55-years old female had complained severe anorectal pain which didn't respond to Western medicine therapeutics during 5 months including 45-day hospitalization. Whereas the symptom was rapidly resolved by the treatment in a Korean medicine hospital, and the clinical outcome was monitored. Result: There was no abnormality explaining the anorectal pain from blood tests, gastrointestinal endoscopy, sonogram and computed tomography for abdomen and pelvis. The patient was diagnosed with a levator ani syndrome. Based on the typical feature of tenderness of lower abdomen as well as beating sign around belly, an herbal drug, Shihogayonggolmoryo-tang (柴胡加龍骨牡蠣湯) was prescribed. In addition, the warm acupuncture at BL 31 to BL 33 and moxibustion on lower abdomen were given to the patient. The anorectal pain was radically reduced from treatment 7-day, and it almost disappeared within treatment 25-day. Conclusion: This case report would provide information for the potential of TKM therapies focused on the refractory levator ani syndrome which no satisfactory therapy exist.

In this paper, we propose a fast intra prediction mode selection method in Scalable Video Coding(SVC) which is an emerging video coding standard as an extension of H.264/Advanced Video Coding(H.264/AVC). The proposed method decides a candidate intra prediction mode based on the characteristic of macroblock smoothness. Statistical analysis is applied to computing that smoothness in spatial enhancement layer. We also propose an early termination scheme for Intra_BL mode decision where the RD cost value of Intra_BL is utilized. Compared with JSVM software, our scheme can reduce about 55% of the computation complexity of intra prediction on average, while the performance degradation is negligible; For low QP values, the average PSNR loss is very negligible, equivalently the bit rate increases by 0.01%. For high QP values, the average PSNR loss is less than 0.01dB, which equals to 0.25% increase in bitrate on average.

Objectives : The aim of this study was to investigate the mechanism and the clinical significance of prohibition of acupuncture of LI4 and SP6 during the period of pregnancy. Methods : It was investigated the prohibition of acupuncture during the period of pregnancy based on the literature reviews. Previous studies identified the acupuncture treatment of animal and clinical studies during the period of pregnancy and labor in China Academic Journal(CAJ). These papers were classified and investigated to clarify the rationale of the prohibition of acupuncture during the period of pregnancy. Results and Conclusions : The contraindicated points during the period of pregnancy are Hapgok (LI4), Samumgyo (SP6), Songmun (CV5), Kwanwon (CV4), Sosang (LU11), Chium (BL67), Kollyun (BL60). The uterine contraction can be induced by the stimuli of Hapgok (LI4) via endocrine system and Samumgyo (SP6) via nervous system. Both Hapgok (LI4) and Samumgyo (SP6) also can be used in various diseases such as induction of abortion, facilitation of parturition, stabilization of embryos, cross birth and so on.

Objectives : To investigate the effects of Cornu cervi parvum pharmacopuncture with regard to the blood picture and antioxidative activity in rats. Methods : Sprague-Dawley rats were divided into 3 groups (n=5 each) and were treated with Cornu cervi parvum pharmacopuncture every other day for 2 weeks. The groups are classified as follows; normal control without treatment (control group), Cornu cervi parvum pharmacopuncture at CV4 (CV4 group), and Cornu cervi parvum pharmacopuncture at BL23 (BL23 group). Thereafter, the blood and liver samples were obtained for blood analysis and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activity measurement. Results : Cornu cervi parvum pharmacopuncture groups showed higher values of red blood cell count and plasma cell volume compared with those of the control (p<0.05). However, hemoglobin level showed no significant differences among groups. With regard to the blood picture, plasma concentration in total protein and albumin showed no significant differences in pharmacopuncture groups, while higher ratio of albumin/globulin was observed in CV4 group. White blood cell counts and its composition showed no significant differences among groups. Pharmacopuncture groups showed higher values in SOD, CAT, and GSH-Px activities compared with those of control group. Conclusions : Cornu cervi parvum pharmacopuncture alleviates oxidative activities in rats.

The present study was performed to elucidate the therapeutic effect by aquapuncture with bee-venom (apitoxin) for treatment of canine pyoderma. The total 8 dogs with pyoderma were divided into 2 groups as control (antibiotics group: 4 dogs) and experimental groups (apitoxin group: 4 dogs). Antibiotics group was treated with bathing and antibiotics, while apitoxin group was treated with bathing and aquapuncture with apitoxin at Fei Shu (BL13), Wei Zhong (BL40), Da Zhui (GV14), Zu San Li (ST36), He Gu (LI04), Qu Chi (LI11), and San Yin Jiao (SP06). Based on the results of changes in clinical symptoms, total leukocyte counts, neutrophil/lymphocyte ratios and histopathological findings, antibiotics and apitoxin groups were all effective for treatment of canine pyoderma, and significant differences were not detected between the groups. It was suggested that apitoxin might be used as an alternative method to antibiotics for treatment of canine pyoderma.

This work aims to obtain basic information for seed propagation of Hydrangea serrata for. acuminata. The germination percentage of the seeds taken on 15 November, 30 December, and 23 January was $90.0{\pm}4.16%$, $84.4{\pm}5.52%$, and $88.9{\pm}2.40%$, respectively. This suggest that seeds of Hydrangea serrata for. acuminata are non-dormant seeds. The optimum temperature for germination was $25^{\circ}C$ and light was necessary. Most of the growth parameters (shoot and leaf length, stem diameter, root length, no. of roots, T/R ratio, and fresh and dry wts.) were significantly greater at $25/20^{\circ}C$ and $25^{\circ}C$ than at the other temperatures. Low T/R ratio at relatively cool temperatures (15 and $20^{\circ}C$) was caused by suppressed top growth. In light quality treatment, red light (RL) significantly enhanced stem elongation. The greatest photosynthetic pigments (total chl, chl a/b, and carotenoid) were observed in seedlings grown in blue light (BL), followed by seedlings grown in RL+BL. When blue light was added, higher pigment contents were found. Effect of plug cell size (50, 72, 128, 162 and 200 cells) on the growth of seedlings was investigated. The highest top growth was observed in seedlings grown in 50 cell trays, followed by seedlings grown in 72, 128, 162, and 200 cell trays. However, there was no significant differences between 162 and 200 cell trays. Especially, smaller size leaves were observed in seedlings grown in smaller cell trays (lower volume and high plant density).

Background: Minor histocompatibility HY antigen, as a transplantation antigen, has been known to cause graft rejection in MHC (major histocompatibility complex) matched donor-recipient. The aim of our study is to investigate the role of male antigen (HY) disparity on MHC matched pancreatic islet transplantation and to examine the mechanism of the immune reaction. Methods: Pancreatic islets were isolated and purified by collagen digestion followed by Ficoll gradient. The isolated islets of male C57BL6/J were transplanted underneath the kidney capsule of syngeneic female mice rendered diabetic with streptozotocine. Blood glucose was monitored for the rejection of engrafted islets. After certain period of time, tail to flank skin transplantation was performed either on mouse transplanted with HY mismatched islets or on sham treated mouse. The rejection was monitored by scoring gross pathology of the engrafted skin. Results: HY mismatched islets survived more than 300 days in 14 out of 15 mice. The acceptance of second party graft (male B6 islets) and the rejection of third party graft (male BALB/c islets) in these mice suggested the tolerance to islets with HY disparity. B6 Skin with HY disparity was rejected on day $25{\pm}7$. However, HY mismatched skin transplanted on the mice tolerated to HY mismatched islets survived more than 240 days. Tetramer staining in these mice indicated the CTL recognizing MHC Db/Uty was not deleted or anergized. Conclusion: The islet transplantation across HY disparity induced tolerance to HY antigen in C57BL6 mouse, which in turn induced tolerance to HY mismatched skin, which otherwise would be rejected within 25 days. The MHC tetramer staining suggested the underlying mechanisms would not be clonal deletion or anergy.

Objectives The objective of this study was to contribute to the development of pharmacupuncture for obesity treatment by reviewing the studies of pharmacupuncture experimentations and clinical trials. Methods We searched the papers with keywords of 'obesity' and 'pharmacupuncture' in the search site, RISS, Oriental medicine advanced searching integrated system(OASIS), Korean traditional knowledge portal, the society of Korean medicine for obesity research, Korean pharmacupuncture institute, the Korean academy of oriental rehabitation medicine and Korean acupuncture & moxibustion society. Results 1. We reviewed 37 articles searched. 27 articles(73.0%) were animal experimentations, 5 articles(13.5%) were cell experimentations, 4 articles(10.8%) were clinical trials and 1 article(2.7%) was study analysis. 2. The herbs, using for animal experimentations, were atratylodes japonica, coix lachrymajobi, ephedra sinica, crataegus pinnatifida, wild ginseng and etc. Acupucture points were joksamni(ST36), zhongwan(CV12), gansoo(BL18), pungnyung(ST40), umnungchon(SP9), bisu(BL20), gokji (LI11), cheun-chu(ST25) and etc. 3. For cell experimentations, preadipocytes and adipocytes performed on cell cultures with using rats, 3T3-L1 preadipocytes and porcine skin including fat tissue were treated with fel ursi, bovis calculus, ephedrae herba, spirodelae herba, wild ginseng. 4. For clinical trials, Sangsik no.1, Bigiheo, ephedra, green tea and sweet bee venom were injected at the region where a lot of fat like zhongwan(CV12), xiawan(CV10), kwanwon(CV4), cheun-chu(ST25) and thigh. Conclusion Through animal and cell experimentations and clinical trials, the treatment of obesity using local acupuncture therapy was effective. For clinical use, however, it is considered that animal and cell experimentation and clinical trial's connection using one kind of herb and studies about more clinical trials and associated side effects are needed.
