The seedlings of the scallop, Patinopecten yessoensis, which were collected in April 1980, April 1981 and May 1981, and the grown-up scallops collected in the sea bottom in November 1979, were reared by hanging method up to the July 1981. The growth of the seedlings collected in April 1980 was greatly affected by the time of the seedling collection, manipulation of the net cage, density in the net cage and the annual water temperature fluctuation. The scallops reared from the spat collected in April 1980 reached the sizes of 0.33 mm, 1.23 mm, 29.34 mm and 59.59 mm in shell length in 40,75, 285 and 450 days respectively. Since then, growth rate was determined as follows based on the age estimated by the year rings on the shell:84.96mm in 19 months, 99.3mm in 31, 112.3mm in 37 and 113.64mm in 43 months. The meat and the adductor muscle weight increased with the shell length. The meat weight roached about 15g when the shell length was 60-70mm and about 94.13 g when 130-140mm, and the adductor muscle weight reached about 4.89 g when the shell length was 60-70 mm and about 39.59g when 120-130 mm. But the growths of the meat and the adductor muscle weight were in stagnancy after scallops reached 125 mm in shell length.

This study was introduced the short-term effectiveness of Oriental medicine treatment for lumbar disc herniation inpatients. We selected 208 inpatients with a magnetic resonance imaging(MRI)-confirmed lumbar disc herniation since June 2012 until August 2012. Their demographics characterisitics, numeric rating scale(NRS) and Oswestry back-related disability index(ODI) for low or leg pain, lumbar flexion and extension angle were assessed at baseline and when discharged from the hospital. When it measured the straight leg raisingscale(SLR), the low side of the angle was examined. Treatment every patient has received as follow; herbal medicine, bee venom, acupuncture and physical examination, spinal manipulation. NRS of low back pain and leg pain and ODI is $5.6{\pm}2.3$, $4.9{\pm}2.8$ and $45.5{\pm}20.0$, respectively at baseline and $2.8{\pm}1.8$, $2.7{\pm}1.9$ and $27.2{\pm}14.1$, respectively when discharged from the hospital. range of motion(ROM) of lumbar flexion and extension angle and SLR is $70.0{\pm}27.1$, $15.4{\pm}7.2$ and $61.3{\pm}23.0$ respectively at baseline and $80.5{\pm}16.9$, $18.25{\pm}4.1$ and $73.2{\pm}14.0$, respectively when discharged from the hospital. It shows that statistically significant improved(P<0.001). Furthermore, regarding patient satisfaction with the treatment, excellent(33.7%), good(55.4%), normal(10.4%), poor(0.5%), it suggests that most patients(89%) satisfied with the treatment.

Using barrier membrane, guided bone regeneration(GBR) and guided tissue regeneration(GTR) of periodontal tissue are now widely studied and good results were reported. In bone regeneration, not all cases gained good results and in some cases using GTR, bone were less regenerated than that of control. The purpose of this study is to search for the method to improve the success rate of GBR and GTR by examination of the cause of the failure. For these study, rats and beagle dogs were used. In rat study, 5mm diameter round hole was made on parietal bone of the rat and 10mm diameter of bioresorbable membrane was placed on the bone defects and sutured. In 1 ,2, 4 weeks later, the rats were sacrificed and Masson-Trichrome staining was done and inspected under light microscope for guided bone regeneration. In dog study, $3{\times}4mm^2$ Grade III furcation defect was made at the 3rd and 1th premolar on mandible of 6 beagle dogs. The defects were covered by bioresorbable membrane extending 2-3mm from the defect margin. The membrane was sutured and buccal flap was covered the defect perfectly. In 2, 4. 8 weeks later. the animals were sacrificed and undecalcified specimens were made and stained by multiple staining method. In rats. there was much amount of new bone formation at 2 weeks. and in 4 weeks specimen, bony defect was perfectly dosed and plenty amount of new bone marrow was developed. In some cases, there were failures of guided bone regeneration. In beagle dogs, guided tissue regeneration was incomplete when the defect was collapsed by the membrane itself and when the rate of resorption was so rapid than expected. The cause of the failure in GBR and GTR procedure is that 1) the membrane was not tightly seal the bony defects. If the sealing was not perfect, fibrous connective tissue infiltrate into the defect and inhibit the new bone formation and regeneration. 2) the membrane was too tightly attached to the tissue and then there was no space to be regenerated. In conclusion, the requirements of the membrane for periodontal tissue and bone regeneration are the biocompatibility, degree of sealingness, malleability. space making and manipulation. In this animal study. space making for new bone and periodontal ligament, and sealing the space might be the most important point for successful accomplishment of GBR and GTR.

Meridian massage is originated from oriental medical manipulation, and it has been mainly applied to as pain and paralysis. The purpose was to develop new method of nursing care for help hemiplegic patients to recover their functions of upper limbs and to reduce depressions. This study was carried out between 8, March, and 8, June, 2000 and the subjects of the study were .60 hemiplegic stroke patients who were participants at a hospitalized in K oriental medical center. The experimental group(30) and the control group(30) were assigned by means of participation order. The experimental group took meridian massage on affected upper limb for 10 minutes daily for 2 weeks. We evaluated muscle power and endurance with band from AVIVA corp.; range of motion with goniometer; shoulder pain with visual analogue scale; swelling with Jeweiers ring measurement of Dirette; depression with self-rating depression scale translated into Korean by Yang(1982). Data were analyzed by SPSS PC and the results are described below. The experimental group showed better muscle power and endurance than control group. Range of motiont of affected shoulder improved significantly in experimental group. Also, the experimental group showed less shoulder pain, hand edema, depression than control group. In this study, we observed that meridian massage is an effective nursing care in improving the function of upper limb and managing depression of stroke patients.

Now that fiscal soundness is increasingly important influenced by the euro area fiscal crisis, early budget execution has been under the spotlight as a tool for economy control, other than typical expansionary method, such as supplementary budget. Basically, early budget execution is a fiscal policy instrument that reponses to economic fluctuations through modifying the inter-temporal allocation of fiscal expenditure within budget, without affecting fiscal soundness. This study empirically examines how effective the intert-temporal reallocation of fiscal expenditure is in economy control. Using Korea's Consolidated Fiscal data, the size of inter-temporal reallocation of fiscal expenditure is defined as changes of fiscal expenditure for one year excluding seasonal factors and used to explain real economic growth rate, a dependent variable. The result shows that the macroeconomic effect of the inter-temporal reallocation turns out meaningful in general, though some policy time lag exists. Meanwhile, a simulation using macroeconomic model finds that overall effect on economic growth is not large because increase in fiscal expenditure allocation at a certain point of time is canceled by the opposite direction within the same fiscal year. However, the inter-temporal reallocation is found to reduce volatility of key macroeconomic variables so as to contribute to partially stabilizing macroeconomy. In particular, such effect of economic stabilization seems to be highly apparent at the time of financial crisis, but not very noticeable in normal economic cycle.

On the point of data quality management, data quality is influenced by quality policy, quality organization, business process, and business rule. Business rules, guide of data manipulation, have effects on data quality directly. In case of building an integration database among distributed databases, defining business rule is more important because data integration needs to consider heterogeneous structure, code, and data standardization. Also data value has various figures depended on data type, unit, and transcription. Finally, database structure and data value problem have to be solved to improve data quality. For handling them, it is needed to draw database integration model and cleanse data in integrated database. NTIS(stands for National science and Technology Information Service) has an aim to serve users who need all information about national R&D by internet, and for that aim, it has a integrated database which has been made with several database sources. We prove that database integration model and data cleansing are needed to build a successful integrated database through NTIS case study.

This study examined the effects of the concentration variation of the silyl hydride (Si-H) functional group in polymethylhydrogen siloxane cross-linker and the vinyl-functional group in silicone prepolymer on the physical properties of the dental polyvinylsiloxane impression materials (PVS). When the SiH/Vinyl ratio was 1.6 (Group $\underline{C6}$ containing ${\underline{C}}ross$-linker $\underline{6}$ parts), the setting rate was too slow even though their tensile strength was the highest within the tested groups. When the SiH/Vinyl ratio was 3.2 (Group C12), the setting rate was too fast to allow appropriate working time even though their mechanical properties were good. The C14 group showed rather lower tensile strength compared to the groups having lower cross-linker contents. Notably, too much incorporation of cross-linker, like C16 group, induced delay of the setting, by which the mechanical and manipulation properties were detrimentally affected.

We examine how women entrepreneurs in contents business experience work/family role conflict and then reveal what kind of conflict management strategies they adopt in varying external and internal conditions. A critical problem faced by female entrepreneur is the tension that exists between their personal lives and business role. This tension is viewed as a form of inter-role conflict in which the role pressure from work and family competes for women's limited time and energy. First, we probe the content and nature of work- family role conflict on the part of female entrepreneurs. Second, we closely look at the three strategies of work/family role manipulation. Family role reduction strategy, work role reduction strategy, and work/family role sharing strategy are identified. Third, we discuss how the choice of the three strategies is affected by internal family salience and the external resources including spouse, family, and financial resources.

Purpose: We examined patients to evaluate the clinical results of traumatic metacarpophalangeal(M-P) dislocations of the thumb, uncommon and irreducible. Materials and Methods: In 11 traumatic M-P dislocations of the thumb, the types of dislocations were 10 dorsal and 1 volar dislocations resulted from the impacted and hyperextended forces on thumb. Authors evaluated the possibility of closed reduction, the anatomical structures interfering with closed reduction, and the surgical approaches. Results: Eight cases were treated with open reduction through volar approach and two cases were treated with closed reduction. Joint fusion was done with a plate in a chronic case. Initial closed reduction was attempted in all cases, but succeeded in only 2 cases because the interposed ruptured volar plate, the flexor pollicis brevis tendon and ulnar sesamoid bone at the volar side of the M-Pjoint were the obstacles to reduce. The metacarpal head was caught in button-hole slit between theflexor pollicis brevis and the ruptured volar joint capsule in all cases. Conclusion: Similar with the M-P joint dislocations of other fingers, the dorsal complex M-P dislocations of the thumb due to hyper extension are unusual and can't easily be reduced by closed manipulation. It is necessary to pay attention to the ruptured volar plate, capsule, the subluxated portion ofthe sesamoid and flexor pollicis brevis as interfering structures.
