This study is carried out to examine the effect of applying Feldenkrais method, elastic band training and combined training on trunk muscle. The subjects of this study were 32 modern dance majors and they were divided into four groups which consists of 8 peoples each, Feldenkrais method group(modern dance + Feldenkrais method), elastic band training group(modern dance + elastic band training), combined training group(modern dance + Feldenkrais method + elastic band training), and control group(modern dance). Measurement variables which are trunk muscle were measured before training, and after 4 and 8 weeks training and the results are as follow: In the left muscle strength change at Centaur 0°, Feldenkrais method group, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and combined training group had significant increase after 8 weeks training. In the left muscle strength change at Centaur 45°, Feldenkrais method group and combined training group showed significant increase after 8 weeks training compared to before training and after 4 weeks training. Also elastic band training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and elastic band training group significantly increased after 8 weeks training compared to before training. In the left muscle strength change at Centaur 90°, Feldenkrais method group and combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group showed significant increase after 4 and 8 weeks training compared to before training, and elastic band training group significantly increased after 8weeks training compared to before training. In the left muscle strength change at Centaur 135°, there was no significant changes. In the right muscle strength change, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the left muscle strength change at Centaur 180°, combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, combined training group showed significant increase after 4 and 8 weeks training compared to before training. From above results, applying 8 weeks regular program of Feldenkrais method, elastic band training and combined training to modern dance majors showed positive changes on improvement of trunk muscle strength and physical strength. Also this study implemented to verify the effects of trunk muscle strength and body balance through supplementary training program, and showed the effects in the training group and control group after 8 weeks trunk muscle strengthening program. Feldenkrais method, elastic band training and combined training are very effective to improve trunk muscle strength of modern dance majors so that continuous implementation and application of these effective training program shall be provided for strengthening trunk muscle.

It is necessary to accurately predict converter losses for optimized design of a high-power DC-DC converter. The losses of switching devices and inductor among the elements of the converter take significantly greater proportion. The current ripple will be determined by the size of the inductance and this inductance value varies depending on the DC amount of inductor current. As the inductance changes according to load current, the change influences not only the inductor loss itself but also the total converter loss. In this paper, for more accurate design of a bi-directional DC-DC converter for 30㎾-class energy storage system, more accurate computational model is proposed considering inductance variation according to the load current change. The inductance changes using variable magnetic cores are verified and converter efficiency is tested through simulations and experiments.

Background/Aims : This study was designed to determine the effect of hepatic fibrotic severity on pharmacokinetics of propranolol in CC1q - treated rats. Methods - 1 mL/kg of 10% CC14 in olive oil was injected intramuscularly to rats twice weekly for 4, 6, 8 and 10 weeks, respectively (n=6). Control (n=6) was a sham - injected equal dose of olive oil for 10 weeks. After intravenous bolus injection of 2 mg/kg propranolol to rats, the serum propranolol concentrations were analyzed for 4 hours at various time points by a HPLC - fluorimetric system, and pharmacokinetic parameters such as Co, MRT, AUC, Vdss, tl/2(p) and CLp were determined. Then, a small amount of hepatic tissue was obtained and subjected to determination of the hepatic 4 - hydroxyproline content, which confirmed the hepatic fibrotic severity. Results : The serum concentrations of propranolol at 0.5, 1, 2 and 4 hours were significantly increased in CC1q-treated rats (p$lt;0.01). In proportion to the duration of CC4 treatment, Co and AUC were significantly increased, and Vdss and CLp were significantly decreased (p$lt;0.001). But MRT and t1/2(β) were not significantly changed. The hepatic 4 -hydroxyproline content was gradually increased in CC4-treated rats (p$lt;0.001). Conclusion - Gradual changes in pharmacokinetic parameters of propranolol were seen to be dependent on the hepatic fibrotic severity. We suggest that gradual dosage modification, according to their hepatic fibrotic severity, is necessary for many drugs administered to patients with chronic liver disease.(Korean J Hepatol 2001;7:181-188)

김명,김기훈,김주영,하현철,안명수,김장민,조향훈,정명섭,장인엽 朝鮮大學校 附設 醫學硏究所 2005 The Medical Journal of Chosun University Vol.30 No.2

Changes of Calbindin D-28k- and c-fos-immunoreactivities in the superior collicuclus after Eye Enucleation. Objective and methods: Calcium-binding proteins (CBPs) play an important role in the protection, differentiation and reorganization of the central nervous system. The effects of neonatal retinal deafferentation on a CBPs, calbindin D-28k were examined immunohistochemically in the superficial layer of the rat superior colliculus. Also early gene familly c-fos was examined to evaluate the neuronal characteristics in the superior colliculus after monocular enucleation. Results: On the experimental side of superior colliculus, the number of calbindin D-28k-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. Appearance of c-fos-like immunoreactivity was represented much more in the ipsilateral superior colliculus than contralateral side within 24h after eye enucleation. Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of calbindin D-28k and c-fos expression.

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).

Aims: Hypoxia enhances lipid droplets accumulation by HIF-dependent mechanism, leading to intra-tumoral fatty metamorphosis which is one of the characteristics of early-stage hepatocellular carcinoma (HCC). We investigated whether lipids and lipids-induced exosomes released from HCC cells can induce a tumor-promoting phenotype. Methods: Human HCC cell lines (Huh-7, SNU-761, and SNU-3058) were incubated with oleic acid (OA) or control vehicle. The released exosomes were isolated, quantified, and applied to HCC cells. Results: Incubation of Huh-7 and SNU-761 cells with OA increased proliferation and migration of cells in a fatty-acid binding protein 3 (FABP-3) dependent manner, whereas SNU-3058 cells did not respond to OA. Furthermore, OA upregulated FABP-3 mRNA expression in Huh-7 and SNU-761 cells, whereas its expression in SNU-3058 cells did not change. OA enhanced release of exosomes from Huh-7 and SNU-761 cells, and exosomes collected form these cells upregulated proliferation and invasion of cells. However, this was not observed in SNU-3058 cells. Exosomes released from OA-treated cells were reduced by the inhibition of rho-associated, coiled-coil-containing protein kinase 1 (ROCK1) or FABP-3. Conclusions: These findings suggest that lipids induce release of exo-somes containing unique cargoes from HCC cells in a FABP-3 dependent manner, which may induce the progression of HCC.

인구통계학적 특성 및 한옥 경험에 따른 한옥이미지와 행동의도 차이 분석

장영화(Young Hwa Chang),김은주(Eun Ju Kim) 한국관광연구학회 2014 관광연구저널 Vol.28 No.5

The study aims to investigate the image of Hanok, the traditional Korean house, and see a gap between the image of Hanok and behavioral intention of people depending on their experience of Hanok. The result shows that people have different ideas about functionality and symbolism of Hanok depending on their gender and symbolism of Hanok differs depending on the region it is located. As a result of investigating the changes of image and behavioral intention for Hanok after visiting it the image people have for Hanok do not change. But when it comes to behavioral intention people tend to revisit Hanok, stay overnight or live in it as they visit it more often. It has been found in the study that the image of Hanok is influenced only by gender and region but not by most of demographic factors. This means that it is possible to promote Hanok without identifying its target market. That most of the behavioral intention gets stronger as the frequency of visiting Hanok increases shows it is necessary to develop active contents to attract people and let them have a positive image of Hanok. The fact that how people feel about Hanok puts an influence on the image of Hanok suggests that positive image of Hanok related to emotion can lead to change people’s intention in the end.

이영주 ( Young Ju Lee ),심창환 ( Chang Hwan Sim ),전순실 ( Soon Sil Chun ) 한국식품영양학회 2009 韓國食品營養學會誌 Vol.22 No.4

Chiffon cakes with 2, 4, 6, 8, or 10% of mulberry powder were made. Specific gravity and batter stability of chiffon cake batter were measured. And moisture content, color, height, weight, texture of chiffon cakes were measured. Consumers also evaluated the chiffon cakes for their liking. Specific gravity of control batter was 0.5 and there were no significant differences between control and chiffon cakes with 2, 4, 6, and 8% of the mulberry powder. The sample with 10% mulberry powder had specific gravity of 0.64 and it was significantly higher compared to the control. Stability of the batters were measured using Turbiscan and the control was the least stable whereas the batter with 2% mulberry powder was the most stable. The moisture content and weight of the cake did not differ between the control chiffon cake and cakes with mulberry powder. The height of the cake was the highest for the control cake at 7.56cm, but the differences between control, and samples with 2, 4, 6, and 8% mulberry powder were not significant. The sample with 10% mulberry powder had lower height of 6.55cm. `L`, `a`, and `b` values of crust decreased significantly with increased content of mulberry powder. Crumb color(`L` and `b` values) decreased as mulberry powder content increased, while the `a` value increased. Hardness significantly decreased as mulberry content increased. However, fracturability and springiness did not differ between control and sample cakes. Resilience of the control and sample cakes prepared with 2% mulberry powder were lowest, and resilience increased significantly as the amount of mulberry powder increased beyond 4%. Control cake was preferred overall by consumers, while the color, softness, and flavor of mulberry powder prepared cakes(particularly 2% powder) were specifically preferred. Mulberry flavor and astringency increased as the amount of mulberry powder increased, while sweetness did not change. The intensity of the egg flavor significantly decreased as the amount of mulberry powder increased. Intensity ratings of off-flavor did not differ among control and sample cakes. We recommend the addition of 2~6% mulberry powder to the recipe for chiffon cake.

본 연구는 심리전문가 수련생을 대상으로 전문가로서의 성장을 목적으로 심리도식치료 및 수용전념치료에 기반한 집단상담 프로그램 개발을 위한 예비연구를 실시하고 그 효과성을 검증하고자 하였다. 이를 위하여 프로그램 개발에 관한 모형을 통해 관련 변인과 총 18회기의 내용을 개발하고 내용타당도를 검증하였으며, D지역 심리전문가 수련생 7명을 대상으로 해당 프로그램을 실시한 후 대응표본 t검증과 효과크기(Cohen’s d)를 산출하여 효과성을 검증하였다. 그 결과, 자기성찰(t=-2.04, df=6, p=.04), 정서인식의 명확성(t=-3.16, df=6, p=.01), 정서적 안정성(t=2.81, df=6, p=.01)이 통계적으로 유의미한 변화를 나타내었으며, 자기수용은 유의미한 수준의 변화를 나타내지는 않았지만(t=-.1.34, df=6, p=.11), 효과크기는 중간수준임으로 나타나(d=-0.50) 더 많은 대상자들을 상대로 실시할 경우, 통계적으로 유의미한 결과를 산출할 가능성이 있음을 확인하였다. 본 연구는 심리도식치료와 수용전념치료를 적용한 집단상담 프로그램을 통하여 심리전문가 수련생들에게 교육분석에 필요한 내용을 체계적으로 제공하고 그 효과성을 검증하였다는 점에서 의의가 있다. 본 예비연구에서 효과성이 검증되었으므로 향후 프로그램의 완성도를 높인 후, 비교집단을 활용한 무선 통제집단연구나 종단연구 등을 통하여서도 반복적인 효과성 검증을 할 것을 제안하였다. The purpose of this study is to develop and verify the effectiveness of group counseling program, based on the Schema Therapy(ST) and the Acceptance-Commitment Therapy(ACT), for the growth of psychological professional trainees. For this purpose, psychological professional trainees(n=7) were surveyed, and research participants were selected. Based on program development model, this study conducted content validity verification, conducted a paired samples t-test, and calculated effect size (Cohen s d) to verify the effectiveness of the 18 session program. As a result, introspection (t=-2.04, df=6, p=.04), clarity of emotional recognition (t=-3.16, df=6, p=.01), and emotional stability (t=2.81, df=6, p=.01) showed statistically significant changes. Although acceptance (t=-1.34, df=60, p=.11) did not show a significant change, its effect size being middle level(d=-0.50) indicates that if the test is conducted in a larger sample, a statistically significant outcome could result. This study is meaningful in that it verified the effectiveness of a systematic expert training program that applies the ST and the ACT. Since the program’s effectiveness has been verified in this preliminary study, it is suggested that a controlled or longitudinal study should be conducted to re-verify the effectiveness of this program.
