The purpose of this study is to offer a holistic description of the role demanded of costume designers to provide qualitative improvement of costume designs for small- and medium-sized musicals. The study accomplishes this by analyzing the relationship between the play and costume design in musicals and also by examining the process and environments in which costumes of small-sized theater companies' original musicals are produced. The methods of study are empirical research of literature related to dress, stage art, and culture & arts from both domestic and foreign publications; research of visual materials related to plays; and production and analysis of theatrical performances in which the researcher has participated as a costume designer. The results of the study are as follows. First, professionalism of the play and visual perfection of the work may be enhanced by costume designers actively participating in meetings with staff from each field of the play. Second, by taking advantage of the unique aspects of the work environment of small-sized theater companies' small- and medium-sized original musicals, such as harsh situations of regular and periodical meetings with all staff member, the designer may consider the director's intentions and concepts of the play, but should display more creative and autonomous design abilities. Third, because the costume designers of small- and medium-sized original musical plays are given a small budget and short production periods, the ability to systematically manage budget and production periods and the ability to flexibly handle unexpected incidents during the play is essential.

Purpose: This study was conducted to compare clinical outcomes and treatment-related toxicities after stereotactic body radiation therapy (SBRT) with two different dose regimens for small hepatocellular carcinomas (HCC) ${\leq}3cm$ in size. Materials and Methods: We retrospectively reviewed 44 patients with liver-confined HCC treated between 2009 and 2014 with SBRT. Total doses of 45 Gy (n = 10) or 60 Gy (n = 34) in 3 fractions were prescribed to the 95% isodose line covering 95% of the planning target volume. Rates of local control (LC), intrahepatic failure-free survival (IHFFS), distant metastasis-free survival (DMFS), and overall survival (OS) were calculated using the Kaplan-Meier method. Results: Median follow-up was 29 months (range, 8 to 64 months). Rates at 1 and 3 years were 97.7% and 95.0% for LC, 97.7% and 80.7% for OS, 76% and 40.5% for IHFFS, and 87.3% and 79.5% for DMFS. Five patients (11.4%) experienced degradation of albumin-bilirubin grade, 2 (4.5%) degradation of Child-Pugh score, and 4 (9.1%) grade 3 or greater laboratory abnormalities within 3 months after SBRT. No significant difference was seen in any oncological outcomes or treatment-related toxicities between the two dose regimens. Conclusions: SBRT was highly effective for local control without severe toxicities in patients with HCC smaller than 3 cm. The regimen of a total dose of 45 Gy in 3 fractions was comparable to 60 Gy in efficacy and safety of SBRT for small HCC.

The purpose of this study is to examine the effect of small group inquiry activities using IIM on the science process skills and scientific attitudes of students in higher elementary grades. To verify research problems, the subjects of this study were fifth-grade students selected from two classes of an elementary school located in Busan : the research group was composed of thirty students who participated in small group inquiry activities using IIM teaching model situation, and the other was composed of thirty students(comparative group) who participated in a teacher map- based learning situation. For six weeks, the small group inquiry activities using IIM were executed in the research group, while the teacher-map based instruction was conducted in the comparative group Test showed the following results: First, the research group showed a significant improvement in their science process skills compared to the comparative group. Second, the research group did not show a significant improvement in their scientific attitudes compared to the comparative group. In conclusion, small group inquiry activities using the IIM teaching model was more effective than the teacher map-based teaching model on science process skills. However, since the study has a limit on the object of the study and the applied curriculum, the additional studies need to be conducted with an extended comparative group and curriculum.

Purpose: This study aimed to evaluate the usefulness of the needle aspiration alternative to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage. Methods: From January 1998 to June 2008, we retrospectively reviewed 38 children treated with needle aspiration as management with suppurative cervical lymphadenitis instead of open surgical drainage. Results: All 38 children underwent only 1 puncture. Two patients (5.2%) out of 38 patients experienced reformation of an abscess and all recovered completely after re-treatment with antibiotics. Minor complications were detected in 2 patients (5.2%). One complication originated from remnant necrotic tissue and the other involved formation of a small scar in two patients, which resolved spontaneously. There were no major complications. Conclusion: Needle aspiration can be a simple, safe, and effective alternative procedure to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage.

Objectives : The purpose of this study was to examine the effects of Alisma canaliculatum Extract (ACE) on pacemaker potentials of small and large intestinal interstitial Cells of Cajal (ICC) in mice. Methods : We used enzymatic digestions to dissociate the ICC in the small and large intestine in mice. The whole-cell patch-clamp method was used to record pacemaker potentials in ICC. Results : 1. The ICC generated the pacemaker potentials in small intestine in mice. ACE (0.1-1mg/ml) induced membrane depolarization and decreased frequency with concentration-dependent manners. 2. Pretreatment with a Ca²⁺ free solution, Na⁺ 5 mM solution or 2-APB, a nonselective cation channel blocker, stopped the small intestinal ICC pacemaker potentials. In the case of Ca²⁺-free solution, Na⁺ 5 mM solution or 2-APB, ACE had no effects on the membrane depolarizations in small intestinal ICC. 3. The ICC generated the pacemaker potentials in large intestine in mice. Membrane depolarization appears regularly in the small intestine, but irregularly in the large intestine. ACE induced membrane depolarization (0.1-1mg/ml) and increased frequency (0.1-0.5mg/ml). 4. Pretreatment with a Ca²⁺ free solution, Na⁺ 5 mM solution or 2-APB, stopped the large intestinal ICC pacemaker potentials. In the case of Ca²⁺-free solution, Na⁺ 5 mM solution or 2-APB, ACE depolarized the membrane depolarizations in large intestinal ICC. 5. In mice, intestinal transit rate (ITR) values were dose-dependently decreased by the intragastric administration of ACE. Conclusions : These results suggest that ACE can regulate the pacemaker activity of ICC and the reaction by ACE is different from the small and large intestinal ICC, and the control of the intestinal motion by ACE may be caused by many complex processes.

The bio-telemetry technologies, that use the wireless miniaturized telemetry module implanted in the human body and transmits several biomedical signal from inside to outside of the body, have been expected to solve the problem such as the patient's inconvenience and the limit for diagnosis. In the case of transceiver system using the wireless RF transmission method, the method of three-dimensional localization for implantable miniaturized telemetry module is necessary to detect the exact position of disease. A new method for three-dimensional localization using small loop antenna in the implantable miniaturized telemetry module was proposed in this paper. We proposed a method that can accurately determine the position of telemetry module by analyzing the differences in the strength of signal, which is received at each of the small size RF receiver array installed on the body surface.

Recently, the necessity of open spaces is increased greatly in the city. But in many reasons, open spaces are diminishing gradually in the existing cities. It is more difficult to keep that space because of expensive land price, and the interests between the neighbors. To solve this problem, the local governments tries to change the street system more convenient to the pedestrian by adapting no vechile street system during some specific time. In this point of view, the street which include fence of school, house, and apartment can be the open space. Especially, removal of the school fence can be a useful solution providing open spaces to small cities suffering from lack of open spaces. In this researching background, several schools in Wonju were selected in this research, some has already been opened, and others yet. Opinions of students, presidents of these schools, and citizens are surveyed about removal of fence. In the basis of this result, we deduce problems followed by removing the fence, and reflect it in the plan of opening the fence to present the guidance to cross over the functional limitation of the fence and use it as a open space.

Objective : This retrospective study investigated the clinical and angiographic characteristics of ruptured true posterior communicating artery (PCoA) aneurysms in comparison with junctional PCoA aneurysms presenting with a subarachnoid hemorrhage. Methods : The medical records and radiological data of 93 consecutive patients who underwent three-dimensional rotational angiography and surgical or endovascular treatment for a ruptured junctional or true PCoA aneurysm over an 8-year period were examined. Results : The maximum diameter of the ruptured true PCoA aneurysm (n=13, 14.0%) was significantly smaller than that of the ruptured junctional PCoA aneurysms (n=80, 4.45±1.44 vs. 7.68±3.36 mm, p=0.001). In particular, the incidence of very small aneurysms <4 mm was 46.2% (six of 13 patients) in the ruptured true PCoA aneurysm group, yet only 2.5% (two of 80 patients) in the ruptured junctional PCoA aneurysm group. Meanwhile, the diameter of the PCoA was significantly larger in the true PCoA aneurysm group than that in the junctional PCoA aneurysm group (1.90±0.57 vs. 1.15±0.49 mm, p<0.001). In addition, the ipsilateral PCoA/P1 ratio was significantly larger in the true PCoA aneurysm group than that in the group of a junctional PCoA aneurysm (mean PCoA/P1 ratio±standard deviation, 2.67±1.22 vs. 1.14±0.88; p<0.001). No between-group difference was identified for the modified Fisher grade, clinical grade at admission, and 3-month modified Rankin Scale score. Conclusion : A true PCoA aneurysm was found to be associated with a larger PCoA and ruptured at a smaller diameter than a junctional PCoA aneurysm. In particular, the incidence of a ruptured aneurysm with a very small diameter <4 mm was significantly higher among the patients with a true PCoA aneurysm.

Gamisamgibopae-tang (GMSGBPT) is a traditional Korean medicine, which has been used for patients suffering from a lung disease in Oriental medicine. In the present study, we examined the biochemical mechanisms of apoptosis by GMSGBPT in NCI-H460 and A549 human non-small-cell lung cancer cell lines. It was found that GMSGBPT could inhibit the cell proliferation of A549 cells in a concentration-dependent manner, however GMSGBPT did not affect the cell proliferation of NCI-H460 cells. Apoptotic cell death in A549 cells were detected using DAPI staining and annexin V fluorescein methods. The induction of apoptotic cell death by GMSGBPT was connected with a down-regulation of anti-apoptotic Bcl-2 and Bcl-xL expression, and proteolytic activation of caspase-3 and caspase-9 in A549 cells. However, GMSGBPT did not affect the levels of pro-apoptotic Bax and Bad expression, and activity of caspase-8. GMSGBPT treatment also concomitant degradation and/or inhibition of poly (ADP-ribose) polymerase (PARP), ${\beta}$-catenin, phospholipase C-1 (PLC${\gamma}$1) and DNA fragmentation factor 45/inhibitor of caspase-activated DNase (DFF45/ICAD). Taken together, these findings suggest that GMSGBPT may be a potential chemotherapeutic agent for the control of human non-small-cell lung cancer cells and further studies will be needed to identify the active compounds that confer the anti-cancer activity of GMSGBPT.
