김찬양,신효근,홍기환,김연희,김현기 全北大學校 語學硏究所 1994 어학 Vol.21 No.-

The methods of the Computed Tomograph and the High-speed Speech analysis system were used for the comparative study of French and Korean oral vowels. Three male native speackers of French and three Korean speakers were selected for these articulatory and acoustic characteristics. The speech materials were the simple French oral vowels / i, e, ε, a, u, o, ??, a / and the Korean oral vovels / i, e, ε, a, w, u, o /, respectively. The results of these studies are as follows : (1) In the case of articulation, the aperture of Korean closed front unrounded vowels is larger than that of French vowels and the Korean back closed vowel /u/ and the half-closed vowel /o/ did not show significant differences with the corresponding French high vowel /i/. But the aperture of the Korean half-open vowel /??/ is smaller than that of French vowel and in this case, the place of articulation for Korean vowel /??/ is more advanced than that of French vowel /??/ (2) By means of spectrographic analysis of the French and Korean vowels, the first formant of the Korean high vowel /i/ is higher than that of French high vowel /i/. This means that the aperture of the Korean high vowel is larger than that of French high vowel. The second formant of French back vowels are lower than those of Korean back vowels. This result shows that the projection of French back vowels is greater than that of Korean back vowels.

이 연구의 목적은 유산소 운동과 저항 운동에 따른 비만 노인여성의 IGF-1, 인슐린 저항성, β-세포 기능 및 PTH에 미치는 영향을 분석하고자 실시하였다. 운동 집단은 유산소 운동(n=10), 저항 운동(n=10), 대조군(n=10)으로 무작위 배정하여 집단 별 동일 시점에서 시작해 일 60분씩 주 3일, 12주간 실시하였으며, 대조군의 경우 동일 기간 주 3회 미만의 가벼운 걷기 외 격렬한 운동은 제안하였다. 연구 결과, 체중은 대조군에서 유의하게 증가하였고(p<.05), 유산소 운동 집단에서 유의하게 감소하였다(p<.05). 골격근량은 저항 운동 집단에서 유의하게 증가하였으며(p<.01), 체지방률은 집단과 시기에 따른 상호작용 효과가 나타났고(p<.001), 집단 내 차이검정 결과 대조군에서 유의하게 증가하였으며(p<.05), 유산소 운동(p<.01)과 저항 운동(p<.001)에서 유의하게 감소하였다. IGF-1의 변화는 집단과 시기에 따른 상호작용 효과가 나타났고(p<.01), 유산소 운동(p<.05)과 저항 운동(p<.01) 집단에서 유의하게 증가하였다. 인슐린 저항성은 집단 간 사후검정 결과 유산소 운동(p<.05)과 저항 운동(p<.05)에서 대조군보다 유의하게 감소한 것으로 나타났다. PTH의 변화는 집단과시기에 따른 상호작용 효과가 나타났으며(p<.01), 집단 내 차이검정 결과 유산소 운동(p<.05)과 저항 운동(p<.01) 집단에서 유의하게 감소하였다. 이상의 결과를 종합해 보면 유산소 운동과 저항 운동은 비만 노인여성의 체지방 감소 및 골격근량 증가 뿐만 아니라 성장호르몬의 향상과 인슐린 저항성 감소 및 PTH 감소 효과를 통해 노인의 대사성 질환 및 만성 질환을 예방하는데 효과적인 비약물적전략이 될 것으로 생각된다. The purpose of this study was to analyze the effects of aerobic and resistance exercise on IGF-1, insulin resistance, β-cell function and PTH in obese elderly women. Participants were randomly assigned to three groups: aerobic exercise(AE=10), resistance exercise(RE=10), and a control group(Con=10). All groups started their interventions simultaneously and engaged in exercise sessions three times a week for 60 minutes per session for a duration of 12 weeks. The result of this study, the weight significantly increased in the control group(p<0.05) and significantly decreased in the AE(p<0.05). Skeletal muscle mass significantly increased in the RE(p<0.01). The body fat showed significant interactions between groups and time(p<0.001) and significantly decreased with AE(p<0.01) and AE(p<0.001). IGF-1 showed a significant interaction between groups and time(p<0.01) and significantly increased in the AE(p<0.05) and the RE(p<0.01). Insulin resistance significantly decreased in both the AE(p<0.05) and the RE(p<0.05) compared to the Con, as revealed by post-hoc. PTH showed a significant interaction between groups and time(p<0.01) and significantly decreased in the AE(p<0.05) and the RE(p<0.01). The results suggest that AE and AE not only lead to a reduction in body fat and an increase in skeletal muscle mass in obese elderly women but also have beneficial effects on improving growth hormone levels, reducing insulin resistance, and lowering PTH levels. Therefore, they are considered effective non-pharmacological strategies for preventing chronic diseases in the elderly women.

김찬양 한국문화융합학회 2022 문화와 융합 Vol.44 No.2

Musical and K-POP aim to express emotions that cannot be conveyed through languages to the public through dance. This study aims to investigate whether the two genres can convey messages by expressing various meanings in numerous dance moves. Bob Fosse’s musical Pippin ’s typical scene has the point of agreed with two other choreographer and I had at the moment. BTS’ song Blood sweet tears contains movements of hand, arms, with upper body and legs, pelvis foots, knees lower body, using whole upper and lower body together subdividing three sections in dance. I precisely study and target it. As a result, Musical and K-POP has same purpose in the performing emotional expresses but, in the same motion showing different usages in the stories. It follows time and space limitation indeed. Nevertheless, in both genre body motions in dance still expresses. As a framed by limitation of times and spaces in this study. Style of dance will changes and turning by cultures or era. Technic of story telling in Musical adopted to K-POP genre in today. Much more public culture developing as second language study needed. Study of dance in time is truly meaningful for aiming.

In this study, shear fracture specimens are designed using finite element analyses for the characterization of ductile fracture criteria of metal sheets. Many recently suggested ductile fracture criteria require experimental fracture data at the shear stress states in the model parameter identification. However, it is challenging to maintain shear stress states in tension-based specimens from the initial yield to the final fracture, and the loading path can be different for the different materials even with the same shear specimen geometries. To account for this issue, two different shear fracture specimens for low ductility/high ductility metal sheets are designed using the sensitivity tests conducted by finite element simulations. Priorly mechanical properties including the Hosford-Coulomb fracture criterion of the aluminum alloy 7075-T6 and DP590 steel sheets are used in the simulations. The results show that shear stress states are well-maintained until the fracture at the fracture initiation points by optimizing the notch geometries of the shear fracture specimens.

Effects of Si and Sn Contents and Heat-Treatment Temperature on the Corrosion Behavior of AISI 439 Ferrite Stainless Steel

김찬양,김도형,정원섭 대한금속·재료학회 2022 대한금속·재료학회지 Vol.60 No.1

This study was conducted to evaluate the corrosion resistance and optimize the heat-treatment process of AISI 439 ferrite stainless steel silicon and tin alloys with reduced chromium. The microstructure of the specimens and deposition under each condition were analyzed. The production of oxide films was compared based on the thickness of the film and the change in the contents of each element. In addition, electrochemical analyses of each heat-treatment condition was used to quantitatively compare corrosion resistance and passive film stability based on the relative chromium, silicon, and tin contents. It was found that the addition of silicon and tin compensated for the decrease in corrosion resistance induced by the chromium reduction. The addition of the two elements inhibited iron (Fe) oxide production in the surface oxide film, thereby improving the corrosion resistance of the material and improving the stability of the passive film. Moreover, the SiO2 and SnO2 layers inhibited the production of Fe oxide and contributed to the stability of the film along with Cr2O3, the main component of the passive film. However, when the heat treatment temperature increased above a specific temperature, the oxide inhibitory effect of the two elements was relatively offset. Nevertheless, further research to optimize the content of the three elements will help develop materials with superior mechanical properties and corrosion resistance.

다각적사례를 통해본 k-pop댄스의 독자적 존재가능성 연구

김찬양,장소정 국제문화기술진흥원 2023 The Journal of the Convergence on Culture Technolo Vol.9 No.6

K-POP plays a key role in the Korean Wave and is becoming more popular over time. In K-POP, K-POP dance plays an important role in increasing public interest and support and reflects the taste of the audience according to the rapidly changing times. In addition, it has a variety of unique choreography forms, such as point choreography and dance that is perfectly in sync associated with the lyrics of the song, so it has sufficient possibility to raise its status independently. In order to examine the fact that K-POP dance is not an element included in K-POP, this researcher tried to investigate the case of interest in -K-POP dance in various ways and to clarify the meaning of the existence of K-POP dance once again. K-POP dance is gaining international interest and support through the mass media through various examples, raising the awareness of choreographers. In addition, <Cover Dance> created the integration of various races and ages. It also continues to help the country’s economic growth while expanding to education. It also serves as a cultural notification in that it promotes Korean culture and manners along with -K-POP dance. However, this researcher emphasizes that for the continuous growth and independence of K-POP dance in the future, a program to cultivate systematic educators are needed, and the efforts of K-POP dance educators and choreographers are needed accordingly.
