Purpose: The purpose of this study was to analyze the clinical results after Steindler flexoplasty. Materials and Methods: We analyzed 6 cases who had nearly normal finger and wrist joint flexion function, but could not flex elbow joint actively because of upper arm type brachial plexus injury. We performed operation during the period from February 1997 to July 2003. There were 5 males and 1 female with mean age of 28 years (range: $19{\sim}51$ years) when Steindler flexoplasty was done. The average follow-up period was 3 years 11 months (range: 12 months${\sim}$7 years 4 months). We assessed active range of motion of elbow joint, muscle power and elbow function by Mayer & Green grade scale at last follow-up. We assessed how much they were favorable for Steindler flexoplasty and had improvement of upper extremity function and correction of deformity. Results: Postoperative, flexion range of elbow joint improved to average $111.7^{\circ}$ (range: $90{\sim}130^{\circ}$). $25.8^{\circ}$ (range: $15{\sim}45^{\circ}$) in flexion contracture and $16.6^{\circ}$ (range: $10{\sim}35^{\circ}$) in pronation contracture were remained. Range of motion of elbow joint improved to average $85.3^{\circ}$ (range: $45{\sim}105^{\circ}$). Flexion power of elbow joint improved to Grade 5 in all cases. Postoperatively on Mayer & Green grade scale, there were excellent in 3 cases(50%), good in 2 cases(33.3%), fair in 1 case(16.7%). On patient's own assessment of functional improvement, there were excellent in 4 cases(66.6%), good in 1 case(16.7%) and fair in 1 case(l6.7%). Conclusion: Steindler flexoplasty can reserve good clinical results with being improved to active flexion of elbow joint in cases who have functional hand and wrist, but paralysis upper arm muscle in brachial plexus injury.

The goal of this study was to investigate the effects of a newly developed functional food containing Bacillus polyfermenticus (BP) and other physiologically active materials on the antioxidant system and the process of colon carcinogenesis in male F344 rats. Following a one-week adaptation period, the rats were divided into 3 groups and fed either a high-fat, low-fiber diet (control and DMH groups), or a high-fat, low-fiber diet supplemented with B. polyfermenticus ($3.1{\times}10^8\;CFU/day$) and other physiologically active materials (chitosan, chicory, ${\alpha}$-tocopherol, and flavonoids) (DMH+BP group). One week after the initiation of the diets, 2 groups of rats were subjected to six weeks of treatment with 1,2-dimethylhydrazine (DMH, 180 mg/kg BW, s.c.). The dietary treatments remained consistent throughout the entire experimental period. Nine weeks after the initial DMH injection, the rats supplemented with B. polyfermenticus had significantly lower numbers of aberrant crypt foci than those in the DMH group. Injections with DMH resulted in significantly higher leukocytic DNA damage and plasma lipid peroxidation levels, as well as in a lower plasma total antioxidant potential. These effects were reversed following supplementation with B. polyfermenticus and other physiological materials. Our results indicate that a functional food containing B. polyfermenticus exerts a protective effect on the antioxidant system and on the process of colon carcinogenesis, thereby suppressing the development of preneoplastic lesions.

Childhood Cancer Foundation of ROC(CCFROC) has been founded since 1982. Its goal is to provide comprehensive care for cancer children and their families. And in turn, under the provision of good and complete care, they can be back to the school and society. To achieve this goal, it needs to get every body's effort of the society together. The foundation has been founder under this concept and tried to fulfil this task. The first step is to educate the public to know that childhood cancer can be cured and the process of treatment is long and expensive. In order to reach this life-saving procedure, campaigns for raising money is most important thing. Then, pediatric hematologists / oncologists try to organize study group, named Taiwan Pediatric Qncology Goupp(TPOG), to make treatment protocols for childhood cancers. Its primary purpose is to increase the cure rate to prove the earlier the diagnosis and treatment, the better the prognosis. The second step is to provide full support of medical expenses and further to give help for emergent need to living. Through the varieties of active exercises of cancer children or families, foundation provides opportunities for them to share the experience during the different periods of diseases. The third step is to extend the scope of training activities for many kinds of personnel who devote to the care for cancer children. On the other hand, it promotes the cooperation or communication with international organizations and sets up recreation playing ground in the communities. The aim is to provide a comprehensive and integrated care for cancer children during their education, breeding and even accomplishment period. Besides the financial support of medical care, it provides social services to give psychological support for children and their families, to strengthen doctor-patients or doctor-families relationship. The foundation provides the mourning religious activities to cherish the memory of their children who passed away and to comfort their sadness. Since the childhood cancer is curable, its treatment should be active, comprehensive and it needs to provide to all cancer children without exception. Indeed, the work of CCFROC should be changed according to the environment and different time period. But, it needs the full support from the society. We hope the scope and content of the work will be more extended and its achievement will be better than now in the future.

Among anti-seismic technologies, base isolation is a very effective means of mitigating damage to structural and nonstructural components, such as equipment. However, most seismic isolation systems are designed for mitigating only horizontal seismic responses because the realization of a vertical isolation system (VIS) is difficult. The difficulty is primarily due to conflicting isolation stiffness demands in the static and dynamic states for a VIS, which requires sufficient rigidity to support the self-weight of the isolated object in the static state, but sufficient flexibility to lengthen the isolation period and uncouple the ground motion in the dynamic state. To overcome this problem, a semi-active VIS, called the piezoelectric inertia-type vertical isolation system (PIVIS), is proposed in this study. PIVIS is composed of a piezoelectric friction damper (PFD) and a leverage mechanism with a counterweight. The counterweight provides an uplifting force in the static state and an extra inertial force in the dynamic state; therefore, the effective vertical stiffness of PIVIS is higher in the static state and lower in the dynamic state. The PFD provides a controllable friction force for PIVIS to further prevent its excessive displacement. For experimental verification, a shaking table test was conducted on a prototype PIVIS controlled by a simple controller. The experimental results well agree with the theoretical results. To further investigate the isolation performance of PIVIS, the seismic responses of PIVIS were simulated numerically by considering 14 vertical ground motions with different characteristics. The responses of PIVIS were compared with those of a traditional VIS and a passive system (PIVIS without control). The numerical results demonstrate that compared with the traditional and passive systems, PIVIS can effectively suppress isolation displacement in all kinds of earthquake with various peak ground accelerations and frequency content while maintaining its isolation efficiency. The proposed system is particularly effective for near-fault earthquakes with long-period components, for which it prevents resonant-like motion.

The Mural Tomb of Xu Xianxiu(AD 571), a high ranking official in Northern Qi period, is located in Taiyuan, Shanxi province, China. Despite having been raided, it was still discovered to contain over 530 pieces, such as artifacts and murals, in excellent state of preservation. These murals are noteworthy for their high level of detail compared to other murals from the same era, and are important for understanding the historical context of active East-West and Han-Hu cultural exchange in the $6^{th}$ to $7^{th}$ century. The murals of Xu Xianxiu's tomb depict round-collared and narrow-sleeved garments as well as straight collared robes typical of the Xianbei tribe's attire. Notable are the ermine fur overcoat and a headwear with flares on the left and right thought to be unique to the Xianbei. The wife and female servants show female attire of the Xianbei at the time; this attire can be characterized by narrow-sleeved long gowns and asymmetrical flying-bird buns. Despite the anti-Han policy of Northern Qi, influences such as the right sided gathering of the robes and embellished hair styles remain. The procession also depicts the three-cornered headdress and long-tailed hood of the Xianbei men, which have been recorded in documents. The large rounded pearl pattern containing the palmette, the divine animal, and bodhisattva's head motifs show the influence of the Western China [Xi'yu]. Considering that Northern Qi had more active interactions with the three ancient kingdoms of Korea than with the Southern Kingdoms[Nanchao], the findings of this study call for further research on the correlation between the attire of ancient Korea and Northern Qi.

PURPOSE. This study was designed to investigate the maintenance of teeth and implants in patients with viral liver disease. MATERIALS AND METHODS. 316 patients without any significant systemic disease were selected as a control group. Liver disease group was consisted of 230 patients. Necessary data were collected using clinical records and panoramic radiographs. Then, the patients were subdivided into 2 groups based on the type of active dental therapy received before maintenance period (Pre-Tx). Analysis for finding statistically significant difference was performed based on the need for re-treatment of active dental therapy (Re-Tx) and change in the number of teeth (N-teeth) and implants (N-implants). RESULTS. Comparing to control group, the patients with liver disease showed higher value on N-teeth, N-implants, and Re-Tx. Statistically significant differences were found on N-teeth (P=.000) and Re-Tx (P=.000) in patients with non-surgical Pre-Tx. Analysis based on severity of liver disease showed that N-teeth and Re-Tx were directly related to severity of liver disease regardless of received type of Pre-Tx. Significant differences were found on N-teeth (P=.003) and Re-Tx (P=.044) in patients with non-surgical Pre-Tx. CONCLUSION. In this study, it was concluded that liver disease might influence the loss of teeth and cause the relapse of dental disease during maintenance period in patients. A significant positive relationship between tooth and implant loss and severity of liver disease seems to exist.

We investigated the gametogenic cycle and spawning seasons of the male Chlamys (Azumapecten) farreri nipponensis by qualitative and quantitative analyses, and also the size at 50% of group sexual maturity was calculated by the data of first sexual maturity. In this study, the male gametogenic cycle of this species by qualitative analysis was divided into five successive stages: early active stage (January to March), late active stage (March to April), ripe stage (April to August), partially spawned stage (July to September), and spent/inactive stage (August to January). The male gametogenic cycle showed similar patterns with monthly changes in the gonadosomatic index and condition index. Particularly, spawning in male scallop occurred once a year from July to September, unlike the spawning period of this species (from June to August) reported by the previous researchers. In quantitative statistical analysis using an image analyzer system, the patterns of monthly changes in the percent (%) of the areas occupied by spermatogenic stages to the testis areas in males showed a maximum in June, and then sharply dropped from July to September, 2006. From these data, it is apparent that the spawning season of C. (A.) farreri nipponensis occurred once per year from July to early September, indicating a unimodal gametogenic cycle during the year. Shell heights at 50% of group sexual maturity (RM50) fitted to an exponential equation were estimated to be 49.90 mm in males (considered to be one year old), and it was 100% for male scallops over 61.0 mm (considered to be two years old).

Purpose: The purpose of this study was to assess the effect of the proprioceptive neuromuscular facilitation (PNF) relaxation technique (hold relax; HR, contract relax; CR) and static stretch (SS) on hamstring flexibility and vertical jump performance in healthy adults over a four-week period. Methods: Twenty-four healthy adults volunteered to participate in PNF and static stretch sessions. The subjects were divided into three groups as follows: 8 subjects in the SS group, 8 subjects in the HR group, and 8 subjects in the CR group. In the HR and CR groups, contractions lasted 15 seconds per trial and consisted of 5 sets of 15 seconds of hamstring contraction immediately followed by 15 seconds of passive static hamstring stretching. For the static group, the participants were asked to stretch by hanging a leg over a table for 30 seconds. Subjects in all groups performed the exercises three days per week for 4 weeks. The active straight leg raising (ASLR) test, active knee extension (AKE) test, and vertical jump test were performed before the intervention and after 1, 2, and 4 weeks. Results: The SS, HR, and CR techniques effected positive improvement in hamstring flexibility and vertical jump performances but neither of the stretching methods had any statistically significant different effects according to group, although there were interactions (between group and time) in the ALSR group from 1 week to 2 week and in the AKE test from pretest to 1 week. Conclusion: Based on the results of the current study, SS, HR, and CR were shown to affect hamstring flexibility and vertical jump performance in healthy adults. In particular, it was determined that within a short period, hamstring flexibility could be attributed more to CR than to SS.

PURPOSE: This study was conducted to identify a more effective intervention in sling and resistance exercise for chronic low back pain patients. METHODS: Seventy (70) subjects were randomly divided into the sling group (SG) and resistance exercise group (REG). Muscular activity of the internal oblique (IO), external oblique (EO), rectus abdominis (RA), and pelvic rotation angle during active straight leg raise (ASLR), a pressure pain threshold (PPT) and a visual analog scale (VAS) were measured. Sling and resistance exercises were conducted for 12 weeks. Intermediate measurements were taken after 8 weeks and final measurements were taken after 12 weeks. RESULTS: Both groups showed significantly decreased RA muscle activity and significantly increased IO muscle activity (p<.05). Additionally, EO muscle activity was significantly decreased in the REG, but significantly increased in the SG (p<.05), while the pelvic rotation angle and VAS were significantly decreased in the SG (p<.05). The pressure pain threshold was significantly increased in both groups (p<.05). CONCLUSION: Based on the results of this study, a 12-week intervention seems to be effective at improving back pain in both groups. However, a lower VAS was seen in the sling group after 8 weeks of intervention. Therefore, it is recommended that the sling be applied first when establishing a chronic back pain treatment program to shorten the treatment period and reduce the pain period.

Phenological events of four Rhododendron tree species (viz. R. arboreum, R. arboreum ssp. delavayi var. delavayi, R. barbatum and R. kesangiae) was monitored in temperate mixed broad-leaved forests of Arunachal Pradesh, India. Phenological events like flower bud formation, flowering, fruit setting, fruit maturing, seed dispersal, leaf bud formation, leaf flushing, and leaf shedding were recorded. Indices i.e., phenophase sequence index (PSI), active phenophasic period of the species (APS) and index of reproductive/vegetative activity (RVA) were also calculated. Present study revealed that bark consistency, growth form and leaf pattern of the studied species have showed variations among the species. Rhododendron species exhibited the phenological events overlapping with other phenophases. The peak flower bud formation was observed during the winter; R. arboreum ssp. delavayi var. delavayi start flowering from December, while the flowering in rest three species exhibited during February to April. Fruit setting occurred during summer to autumn while fruit maturation revealed peak during November. Leaf bud formation illustrated two peaks in April and May, leaf flushing exhibited peak in June, while leaf shedding peaked during October to November. Active phenophasic period of the species were found 12 months, which revealed that species engage in various phenophase activities throughout the year. Phenophase sequence index ranged between 0.8 to 0.9 (PSI ${\geq}0.6$), signifies that species have a sequential arrangement of phenophases. Index of reproductive/vegetative activity of the species exemplified >1, indicate that the reproductive phenophases were dominance over vegetative phenophases. The study have provided substantial insight on the life cycle events of Rhododendron species and ecological approaches for further scientific study with recent climate change and effective management and conservation.
