As South Korea rapidly enters a super-aged society, various improvements are being explored in response to a shrinking population and aging demographics. This study aims to explore the activation characteristics of age-friendly streets designed to foster community among the elderly. The research involved an examination of the sense of place and overall classification characteristics of streets, focusing on their interactive features. Following this, attributes related to the elderly were identified using the WHO’s Age-Friendly Cities Guide and an analysis of sector-specific indicators influenced by elderly contact. This led to the identification of five key characteristics: functionality, aesthetics, commercial viability, cultural relevance, and policy. The scope and methodology of the study involved a comparative analysis using these characteristics, focusing on the ‘Rakhee Street’ pilot project and the ‘Walkable Street’ in Yeokchon-dong, Seoul, which has a high elderly population ratio. The analysis identified a significant need for functional aspects to achieve age-friendly elements. These efforts could serve as a basis for future strategies to create age-friendly streets and broadly contribute to the revitalization of streets.

This study aimed to determine the optimal disinfection method and temperature for germinating ‘Namdo’ garlic bulbils in order to use the garlic shoots as a new leafy vegetable. Two different disinfection methods utilizing either NaOCl or ultralviolet (UV) treatments were evaluated by measuring the germination rate of bulbils and the frequency of infection events. The NaOCl method involved treatments with NaOCl concentrations ranging from 0% to 4% for different periods from 15 up to 60 minutes, whereas under UV treatments only the irradiation time was varied. Germination rates of bulbils were assessed after soaking in 2.0% NaOCl and incubation at three different temperatures: 20, 25, or 30°C. Varying the bulbil soaking period did not result in different germination rates, however, it did reduce the infection frequency, with more extended soaking periods resulting in fewer infection events. Comparative analysis of all different parameter combinations revealed that the highest germination rate was observed when bulbils were incubated in 2.0% NaOCl for 45 min or in 3% of NaOCl for 30 min. Irradiation with UV light for 4 hours resulted in the highest germination rate among the irradiation durations, albeit the germination rate was reduced compared to the NaOCl-mediated disinfection method. Temperature was negatively correlated with germination rate, while more infection events observed at higher temperatures, with 20°C being the optimal temperature. We suggest incubation of ‘Namdo’ garlic bulbils in either 2.0 or 3.0% NaOCl solution with more than 30-min soaking time followed by incubation at 20°C to achieve the highest germination rate with low occurrence of infection events.

키스 쟈렛(Keith Jarrett)의 음악을 통해 본 현대 재즈의 위상에 대한 고찰

전윤한(Jeon, Yoon han) 한국문화산업학회 2015 문화산업연구 Vol.15 No.2

100여 년 전 미국에서 태동한 재즈는 그동안 상업적, 대중적 측면에서 의미를 가지는 음악장르의 하나로 성장해 왔다. 그럼에도 불구하고 여전히 그 정의나 위상에 대해서는 의견이 분분하다. 가장 큰 이유는 상대적으로 짧은 역사에도 불구하고 다양한 음악 장르와 교류해 오면서 형식적 측면에서 너무나 다양한 스펙트럼을 가져온 것에 있다고 볼 수 있다. 본 연구는 현재까지 여전히 음악활동을 하고 있는 키스 쟈렛이라는 재즈 뮤지션의 음악세계를 통해 현대 재즈의 위상에 대한 특징을 살펴보는 것이다. 이를 위해 그의 음악적 변천사를 검토하였으며, 가장 큰 특징으로서 그의 즉흥연주와 공간적 확장성에 대해 알아보았다. 키스 쟈렛으로 대표되는 지난 반세기간의 재즈는 현실을 표현해 내고자 하는 뮤지션으로서의 예술적 욕망을 보다 자유롭고 다양한 형식으로 분출하고자 하는 재즈 뮤지션들의 노력이 집적되어 온 것이며, 이러한 다양한 실험적 정신과 실천들은 여전히 진행 중인 것으로 보인다. 또한 단순히 형식적인 측면에서의 변화를 뛰어 넘어, 시장 혹은 연주자 자체의 세계화를 통해 현대 재즈는 새롭게 진화하고 있는 것으로 보인다. Jazz which was originated in the United States almost 100 years ago, has grown and expanded in terms of commercial and popular aspects. There is, however, a great diversity of opinion howyou define its status. Themain reason could be that it has developed and experienced toomuch wide spectrum as far as its musical forms are concerned, while it has interacted with other genre of music despite relatively short history. This study attempts to verify the features of modern, so called contemporary jazz by investigating the musical perspectives of Keith Jarrett, an eminent figure of jazz who still leads this genrewith great popularity. Changes and transition of hismusical world are reviewed and, his improvisation style and spatial expandability of hismusical practice are particularly examined. This study argues that contemporary jazz has been formed by accumulating every efforts of jazz musicians such as Keith Jarrett, who have endeavored to express their artistic impulse in a more free and honest way as musicians. Which experimental spirits and practices are still progressing. In addition, besides its formal transition, contemporary jazz has been evolving toward a newstage through geographical globalization ofmusical performers aswell as itsmarket. 100여 년 전 미국에서 태동한 재즈는 그동안 상업적, 대중적 측면에서 의미를 가지는 음악장르의 하나로 성장해 왔다. 그럼에도 불구하고 여전히 그 정의나 위상에 대해서는 의견이 분분하다. 가장 큰 이유는 상대적으로 짧은 역사에도 불구하고 다양한 음악 장르와 교류해 오면서 형식적 측면에서 너무나 다양한 스펙트럼을 가져온 것에 있다고 볼 수 있다. 본 연구는 현재까지 여전히 음악활동을 하고 있는 키스 쟈렛이라는 재즈 뮤지션의 음악세계를 통해 현대 재즈의 위상에 대한 특징을 살펴보는 것이다. 이를 위해 그의 음악적 변천사를 검토하였으며, 가장 큰 특징으로서 그의 즉흥연주와 공간적 확장성에 대해 알아보았다. 키스 쟈렛으로 대표되는 지난 반세기간의 재즈는 현실을 표현해 내고자 하는 뮤지션으로서의 예술적 욕망을 보다 자유롭고 다양한 형식으로 분출하고자 하는 재즈 뮤지션들의 노력이 집적되어 온 것이며, 이러한 다양한 실험적 정신과 실천들은 여전히 진행 중인 것으로 보인다. 또한 단순히 형식적인 측면에서의 변화를 뛰어 넘어, 시장 혹은 연주자 자체의 세계화를 통해 현대 재즈는 새롭게 진화하고 있는 것으로 보인다.

본 연구는 잎마늘 생산을 위한 마늘 주아의 최적 주아 크기와 재식밀도를 알아보기 위함이다. 첫번째 실험에서 0.2g 이상의 주아를 대주아로, 이하를 소주아로 나눈 후 대주아는 13,680bulbils/㎡와 18,240bulbils/㎡, 소주아는 18,240bulbils/㎡와 22,800bulbils/㎡의 재식밀도로 치상하였다. 발아율, 초장과 총 수확량을 측정하였다. 두번채 실험에서, 200립의 박피된 주아의 길이, 폭, 생체중과 건물중는 발아시, 발아기와 발아율의 상관를 분석하기 위해 측정되었다. 첫번째 실험에서, 발아율은 대주아에서 가장 높았다. 잎마늘 재배를 위해 재식밀도18,240bulbils/㎡가 가장 높은 발아율 때문에 가장 적당한 재식밀도였다. 수확량의 경우 생체중과 건물중 모두 대주아가 소주아에 비해 2.8배 가량 높은 것을 알 수 있었다. 주아의 형태적 특성과 생체중과 건물중 및 폭 간은 정의 상관을 보였다. 또한 발아율은 생체중과 폭간의 정의 상관을 보였다. 그리고 발아시와 발아기는 생체중과 폭 간의 부의 상관을 보였다. 그럼으로, 결론적으로, 적정 재식밀도는 18,240bulbils/㎡의 재식 밀도와 0.2g 이상의 주아 크기였다. 그러나, 더 두껍고 두 무거운 주아가 더 높은 더 빠른 발아율을 이끌 수 있다. The objective of this study was to find out the most optimal bulbil size and planting densities of garlic bulbils to germination for production of leaf garlic. In the first this experiment, the bulbils classified by the size of bulbil to Big (>0.2) and Small (≤0.2), were planted at 13,680 bulbils/㎡ and 18,240 bulbils/㎡ (Big), 18,240 bulbils/㎡ and 22,800 bulbils/㎡ (Small), respectively. The germination rate, plant height and total yield were measured. In the second experiment, length, width, fresh weight and dry weight of 200 garlic bulbils were measured to analyze the correlation of days to first germination, T50 and germination rate. In the first experiment, the germination rate showed the highest at Big bulbils. The density of 18,240 bulbils/㎡ was the most suitable for cultivation because of the highest germination rate. In the case of yield, it was found that both of the fresh weight and the dry weight of Big bulbil was 2.8 times heavier than Small bulbil. Therefore, Big bulbil with the density of 18,240 bulbils/㎡ was the most suitable for cultivation because of the highest yield. The correlation between each factor of morphological characteristics had a positive correlation between fresh weight, dry weight and width. Also, the germination rate had a positive correlation with fresh weight and width. And, days to first germination and T50 had a negative correlation with fresh weight and width. In conclusion, the optimal planting density is 18,240 bulbils/㎡ and the optimal size of bulbil was 0.2g or more. However, thicker and heavier bulbils could lead to higher and faster germination.

전윤한(Yoon-Han Jeon),황윤식(Yun-Sik Hwang),박흥석(Heung-Seok Park),김인수(In-Soo Kim) 한국생산제조학회 2015 한국생산제조학회지 Vol.24 No.4

In this study, the linear quadratic Guassian loop transfer recovery (LQG/LTR) control technique was combined with an integrator and applied to an inchworm having piezoelectric actuators for precise motion tracking. The piezoelectric actuator showed nonlinear response characteristics, including hysteresis, due to its ferroelectric characteristics and the residual displacement phenomenon. This paper proposes a feedback control scheme using the LQG/LTR controller with an integrator to improve the ability to track the response to complex input signals and to suppress the phenomenon of hysteresis and residual vibration. Experimental results show that the developed feedback control system for an inchworm can track the various motion contours quickly without residual vibration or overshoot.

Antihypertensive effects of ethanol extracts of Aralia elata (Miq.) Seem. (AE) were investigated in spontaneously hypertensive rats (SHR). SHR aged 14 weeks were treated for 8 weeks with AE (10 or 50 mg/kg/day) or amlodipine besylate (Am; 10 mg/kg/day) orally. Hypertension results in injury to several organs and can produce a significant increase in malondialdehyde (MDA) content as a result of lipid peroxidation and endothelial dysfunction. In this study, oral administration of AE and Am significantly reduced systolic blood pressure, organ weight index, and MDA content in tissues but increased significantly the plasma nitrite and nitrate concentrations. The endothelium-dependent relaxant activities of acetylcholine ($10^{-10}-10^{-3}M$) in norepinephrine (NE)-precontracted aorta were increased in AE- and Am-treated rats. Particularly strong endothelium-dependent relaxant activities were observed in AE-treated (50 mg/kg) rats. The endothelium-independent relaxant activities of sodium nitroprusside ($10^{-10}-10^{-3}M$) in NE-precontracted aorta were not changed. The results of this study suggest that AE has both antihypertensive and end-organ protective effects in SHR.
