A total of 48 different volatile oils were identified form P. brevitarsis larvae by gas chromatography/mass spectrometry (GC/MS). Acids (48.67%) were detected as the major group in P. brevitarsis larvae comprising the largest proportion of the volatile compounds, followed by esters (19.84%), hydrocarbons (18.90%), alcohols (8.37%), miscellaneous (1.71%), aldehydes (1.35%) and terpenes (1.16%). The major volatile constituents were 9-hexadecenoic acid (16.75%), 6-octadecenoic acid (14.88%) and n-hexadecanoic acid (11.06%). The composition of fatty acid was also determined by GC analysis and 16 fatty acids were identified. The predominant fatty acids were oleic acid (C18:1, 64.24%) followed by palmitic acid (C16:0, 15.89%), palmitoleic acid (C16:1, 10.43%) and linoleic acid (C18:2, 4.69%) constituting more than 95% of total fatty acids. The distinguished characteristic of the fatty acid profile of P. brevitarsis larvae was the high proportion of unsaturated fatty acid (80.54% of total fatty acids) versus saturated fatty acids (19.46% of total fatty acids). Furthermore, small but significant amounts of linoleic, linolenic and γ-linolenic acids bestow P. brevitarsis larvae with considerable nutritional value. The novel findings of the present study provide a scientific basis for the comprehensive utilization of the insect as a nutritionally promising food source and a possibility for more effective utilization.

Hyelim Oh,Animesh Animesh,Alain Pinsonneault 한국경영정보학회 2019 한국경영정보학회 학술대회논문집 Vol.2019 No.11

This paper examines how the wisdom of crowds can be leveraged in crowdsourced ideation-based product innovation where individual consumers co-create value together with firms. Specifically, we examine how the distribution of contribution equality (DCI) mediates the effect of interdependence on ideation project success. To address the research question we collected data from Quirky platform, which leverages the crowd in the ideation phase of new product development. The analysis of Quirky’s product co-development project affiliation networks (i.e., a two-mode network constructed from inventor and co-inventor collaborations) shows that the mechanism through which interdependence affects the outcome and find that (long-tail) distributional pattern of contribution inequality mediates the relationship between interdependence and crowdsourcing performance, such that higher is DCI, lower is project success. This study provides practical implications for crowdsourcing platform designers by demonstrating the importance of guiding and managing project team composition in crowdsourced ideation projects.

Characterization of carbon nanofiber (CNF)/polymer composite coated on cotton fabrics prepared with various circuit patterns

Hyelim Kim,이선희 한국의류학회 2018 Fashion and Textiles Vol.5 No.1

Fabric heating elements with carbon nanofiber (CNF)/Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) composite coated cotton fabrics were prepared with various circuit patterns with the aim of providing more flexible and uniform heating performance compared to conventional fabric heating elements. To investigate the properties of the fabric heating element according to the pattern condition, patterns consisting of 3, 5, and 7 horizontal lines, i.e., P3, P5 and P7, were respectively used; and subsequently, vertical lines were added to the horizontal lines, i.e., 2P3, 2P5 and 2P7, respectively. P0 was used as the referencesample. P0 showed a surface resistance of 1.2 × 103 Ω/sq at a current of 0.85 A and an electric heating temperature of 76.9 °C. P3 and 2P3 showed better electrical and electric heating properties than other samples, showing surface resistance values of 1.0 × 103 and 1.2 × 103 Ω/sq at the current values of 0.20 and 0.25 A, and surface temperatures of 71.8 and 75.7 °C, respectively. Although the currents applied to P3 and 2P3 were lower than that applied to P0, the electrical heating properties were modified to be similar. In terms of mechanical properties and water repellency, it was shown that the coated fabrics had higher values compared to the uncoated fabric. It was thus suggested that a small amount of CNF/PVDF-HFP composite can be used to manufacture an electric heating element with excellent performance.

Nutrition Intervention through Interdisciplinary Medical Treatment in Hospice Patients: From Admission to Death

( Hyelim Kang ),( Yu Jin Yang ),( Juyeon Park ),( Gyu Jin Heo ),( Jeong-im Hong ),( Hye-jin Kim ) 한국임상영양학회 2018 Clinical Nutrition Research Vol.7 No.2

The demand for hospice services as well as for ‘well-dying’ of terminal patients is increasing as patient financial burden is decreasing due to National Health Insurance coverage for hospice care. Hospice institutions utilize interdisciplinary teams comprising doctors, nurses, dietitians, and other health staffs to provide comprehensive patient management. This report examined the nutritional status of a hospice patient from admission to death as well as the nutrition management of this patient in the hospice ward through nutrition interventions performed by a dietitian in the interdisciplinary team. The patient in the present case was a 74-year-old man diagnosed with pancreatic head cancer who died after 26 days of hospice care following transfer from the general ward. During hospice care, the dietitian monitored the patient's nutritional status and performed 8 nutrition interventions, but his oral intake decreased as the patient's symptoms worsened. The average energy intake rates were 30% and 17% of required rates for oral and artificial nutrition, respectively. In line with a report suggesting that the main focus of nutrition in palliative care should be on improving the quality of life and reducing worry in patients, rather than aggressive nutritional management, there is a need for nutrition interventions that are personalized to individual patients by monitoring progress and offering continuous counseling from the time of admission. In addition, further studies such as comparative analysis of nutritional management in Korean hospice ward will be needed for better nutrition management for terminally ill patients.

Horizontal Movement in Korean Traditional Music : Analysis of Sngkn Kim’s Taegŭm Quartet 20064 8)

Hyelim Kim 이화여자대학교 음악연구소 2016 이화음악논집 Vol.20 No.2

본 논문은 한국전통음악의 현대화 작업에 집중한 한국 작곡가 김승근의 작품 분석을 기반으로 하였다. 이 작곡가는 학창 시절 한국 전통 관악기인 대금을 배운 경험을 바탕으로 일찍이 연주자의 관점에서 음악창작을 하는 데에 관심을 기울여 왔다. 연주 경험을 통해 배운 전통 음악을 최대한 존중한 창의적 해석은 그의 작품에서 두드러지게 나타나는 특징이다. 김승근의 작품 ≪대금 사중주 2006≫은 한국 전통 곡인 ≪수제천≫에서 요소를 담아왔다. 그는 본인의 곡 안에서 평행하게 움직이는 악기군과 각각의 악기를 통해 보여지는 세밀한 음색과 음고의 변화는 ≪수제천≫에서 보여지는 선율에 영감을 받아 작곡하였다고 주장한다. 본 논문은 김승근의 ≪대금 사중주 2006≫을 한국전통 음악을 기반으로한 또 다른 작곡가인 윤이상의 곡과 비교 하여 분석해보고자 한다. 윤이상(1\917–1995)은 독일에 상주하면서 ‘아시아의 소리’를 현대 음악을 통해 재현해 내었다는 명성을 지니고 있는 세계적인 작곡가이다. ≪대금 사중주 2006≫은 ≪수제천≫이 가지고 있는 전통적인 개념을 기반으로 구조로서의 거시적 요소와 선율을 구성하는 미시적 요소로 이루어져 있다. 윤이상의 작품의 경우 김승근 작곡가의 미시적 요소의 대칭되는 부분으로서 주요음(Haupttön)이 쓰였다. 윤이상 작품에서 보여지는 거시적 장치로서의 수직적인 화음 구성은 유럽 아방가르드 음악의 영향을 받은 것으로써 각각의 악기 군이 가지고 있는 평행적 운동을 강조한 김승근의 작품과는 대조된다. 김승근은 선율의 수평적 운동이야 말로 한국 전통 음악이 가지고 있는 특징 중 하나라 주장하며 자신의 특성을 규정한다. 더불어 그는 한국 전통 음악의 새로운 응용은 직접적으로 배운 경험을 바탕으로 한, 음악적 뿌리에 대한 심도 있는 이해를 기반으로 이루어져야 한다는 사실을 작품으로 증명해 준다. This paper will analyse a Korean composer who is devoted to new music for Korean traditional music, Sngkn Kim (b.1967). The composer had also studied the taegŭm (Korean transverse flute) and has developed an understanding of the performer’s perspectives on music making. The intimate relationship between musicians and music opened his eyes to the contexts within which performances actually takes place. His composition, Taegŭm Quartet 2006 (2006), draws on elements from the traditional piece, Sujech’ŏn, dating from the Chosŏn dynasty (1392–1910). The concept of time in the piece, particularly interested him; slow tempos allowed the parallel movement of instrumental clusters which had formed through subtle changes of timbre and pitch. I will compare the Taegum Quartet 2006, with Sujech’ŏn as a historical source and with Isang Yun’s compositions. Isang Yun (1917–1995), was the most famous Korean composer of the post-war generation. Yun, who studied Western art music and settled in Germany, gained an international reputation as a composer who created an Asian ‘tone’. Taegŭm Quartet 2006 uses the philosophical foundation of Sujech’ŏn, as it connects melodic components with the overall structure of the entire piece. The Haupttön (main tones) technique of Isang Yun can also be applied on the larger scale. However, Yun’s perception on the vertical movement of harmonic structures is based on the European avant-garde and this challenges horizontal movements of individual tones. Sngkn Kim is critical of Yun’s ideas on the movement of tones, which he felt were detached from the traditional sounds that form their essence. To Kim, then, the most important factor is a proper understanding of the original context. Korean traditional music must rely on individuals who are willing to accept the tradition as a whole by learning it first-hand, not as fragmented components that assist with some other ideology.

Ralstonia solanacearum Type III Effectors with Predicted Nuclear Localization Signal Localize to Various Cell Compartments and Modulate Immune Responses in Nicotiana spp.

Hyelim Jeon,Wanhui Kim,Boyoung Kim,Sookyeong Lee,Jay Jayaraman,Gayoung Jung,Sera Choi,Kee Hoon Sohn,Cé,cile Segonzac 한국식물병리학회 2020 Plant Pathology Journal Vol.36 No.1

Ralstonia solanacearum (Rso) is a causal agent of bacterial wilt in Solanaceae crops worldwide including Republic of Korea. Rso virulence predominantly relies on type III secreted effectors (T3Es). However, only a handful of Rso T3Es have been characterized. In this study, we investigated subcellular localization of and manipulation of plant immunity by 8 Rso T3Es predicted to harbor a nuclear localization signal (NLS). While 2 of these T3Es elicited cell death in both Nicotiana benthamiana and N. tabacum, only one was dependent on suppressor of G2 allele of skp1 (SGT1), a molecular chaperone of nucleotide-binding and leucine-rich repeat immune receptors. We also identified T3Es that differentially regulate flg22-induced reactive oxygen species production and gene expression. Interestingly, several of the NLS-containing T3Es translationally fused with yellow fluorescent protein accumulated in subcellular compartments other than the cell nucleus. Our findings bring new clues to decipher Rso T3E function in planta.

Characterization of embroidered textile-based electrode for EMG smart wear according to stitch technique

Hyelim Kim,Soohyeon Rho,Daeyoung Lim,Wonyoung Jeong 한국의류학회 2023 Fashion and Textiles Vol.10 No.1

This study fabricated and evaluated the textile-type electrodes for application to smartwear that can measure surface electromyography(sEMG). It was manufactured by lock stitch(LS) and moss stitch(MS), and the stitch distance was prepared as 1, 2, or 3 mm. The surface and compression property was measured by using the Kawabata evaluation system, and the sheet resistance and skin-electrode impedance were analyzed. The coefficient of friction(MIU) of the MS was larger than that of the LS. On the other hand, the geometrical roughness(SMD) showed a smaller value. When the same load was applied, the compressive range of the MS was larger than the LS. When it was manufactured as a leg sleeve and worn, the conductive path could be increased as the loops made of conductive yarn become flat as the loops adhere to the skin by the pressure of clothing. Accordingly, the skin-electrode impedance decreased by increasing the area in contact with the skin. As the results of the RMS(root-mean-square), the LS was higher than the MS in a stable. Nevertheless, the SNR(signal-to-noise ratio) value was lower than that of the MS because movement generated noise during operation. Therefore, more stable signal acquisition is possible when applying MS. It is expected that could be applied to producing smartwear for sEMG measurements with superior sEMG signal acquisition performance while having a softer touch and flexibility.

Prevalence and Incidence of Neuromyelitis Optica Spectrum Disorder in Korea: Population Based Study

HYELIM LEE,Jae Young Kim,Jin Myoung Seok,Yoon-Ho Hong,Nam Gu Lim,신하영,Byung-Jo Kim,황순영,민주홍,김병준 대한의학회 2020 Journal of Korean medical science Vol.35 No.17

Background: Although neuromyelitis optica spectrum disorder (NMOSD) is known to be a rare disease, its prevalence and incidence have not yet been studied in Korea. We performed a population-based study to examine the prevalence and incidence of NMOSD in Korea using data from the Korean National Health Insurance (NHI) claims database. Methods: Data from 2013 to 2017 were obtained, with a washout period set as 2013 and 2014. The prevalence and incidence of NMOSD in 2016 and 2017 were calculated using population census data. Subjects were divided into 5 groups at 15-year intervals, depending on the age at which the diagnostic code was entered. The relative risk (RR) for each age group was compared with the oldest (≥ 60 years) age group. Results: The overall prevalence was estimated to be 3.36 and 3.56 per 100,000 individuals, with an incidence of 0.41 and 0.65 per 100,000 individuals-year in 2016 and 2017, respectively. The mean age was 43.08 (standard deviation, 14.56) years, and the ratio of male to females was 1:4.7. The incidence was higher in female individuals aged between 30 and 59 years (RR, 2.8–3.05; P < 0.05). Conclusion: Nationwide prevalence of NMOSD in Korea was 3.36 and 3.56/100,000 and its incidence was 0.41 and 0.65/100,000-year in 2016 and 2017 respectively.
